▼ Service Oriented Applications (SOA) are designed and developed as a collection of interdependent models using the approach of Model Driven Architecture (MDA). Subsequent reuse of such models in different states of abstraction requires them to be modeled with orthogonal dimensions of variability. The key objective of adopting service orientation in application development is to maximize reuse of both strategic and operational type business functions. Such business functions are developed in the form of processes and services across multiple applications required for different usage contexts. This thesis presents a goal oriented methodological framework to address variability management in service oriented systems. Variability Management (VM) as a research field has received considerable academic as well as industry attention in the last few years. Most of the current approaches, associate variability tightly in the context of new system design and development. For example, the techniques for validating the readiness of existing software systems towards supporting variability has been mostly ignored. This can result in erroneous and redundant modifications. Therefore, there is significant research space that left to be convincingly covered to develop formal techniques for context-driven variant generation, goal-driven variant validation, identifying candidate variants from asset repositories and so on. Goal decomposition models are always found to be effective in capturing and relating requirements stated by different stakeholders of a business organization. A goal represents of intended operational states that an organization seeks to realize in a formalized approach. In this research work, goal is treated as a binding guidance for designing or adapting multiple variants associated with a process design. The aspect of goal preserving variations has not been addressed adequately in existing research on variability management. As a goal model efficiently captures multiple stakeholder expectations on a given system, it must be ensured that both the discovered and derived variants of a given system are goal preserving in nature. This requires the ability to formally reason the correlation and differentiation of such variants in terms of their semantic alignment with a given set of goal models. This thesis presents a novel framework that supports variability management in SOA-based systems. In particular, a formal mechanism called Goal Oriented Variability Management (GOVM) for reasoning, representing and realizing possible goal preserving variations for a given system is provided. It successfully demonstrates how semantically annotated process models in BPMN notation and goal models in UML notation can be leveraged in an integrated fashion. It also provides a lattice based algebraic approach to formally organize a collection of variants with or without partially ordered relationships (Containment, Composition, contextual, Dependency, goal alignment) between them.

▼ Land degradation, climate variability, socio-economic changes and population increase, are shrinking grazing lands making forage availability less predictable and affect the resilience of pastoralists communities. Interventions to improve pastoralists' resilience include the introduction of policies that offer pastoralists alternative sources of livelihood and encourage livelihood diversification that is climate-proof. Though viable, these interventions are not sustainable and often fail because they lack to embrace the needs, aspirations and preferences of these uniquely cultured communities. This research taps into the potential of range reseeding as an intervention that can rehabilitate degraded lands for profitable use ultimately improving their resilience to climate variability and other interrelated challenges by engaging in diverse income generating activities without having to change their culture which is entirely livestock based. This study uses two pastoral communities, the Tugen and the Njemps from Lake Baringo, Kenya to study the dynamics of range reseeding as pastoralists who own, manage and use reseeded fields. The study interviews 193 pastoralist households and determines characteristics of adoption of the range reseeding exercise, field use, herd characteristics and the challenges of the different localized geographical landscapes to these two communities. The results suggest that these communities are different in several ways. The Tugen community initially reseed more fields than the Njemps, but later, the Njemps reseed more fields and of larger sizes. The two tribes also differ in their field use with Tugen participating more in cutting thatching grass while the Njemps prefer to engage in fattening programs, two activities with varying levels of profitability. Each community also faces different sets of challenges based on their geographical landscapes. Invasive species and short term flooding is the greatest challenge among the Njemps, while insecurity resulting from resource based conflicts is common among the Tugens. The average survival rate for livestock following the 2019 drought was 75% with both communities having similar herd sizes per household. Through these findings, the study advocates for range reseeding to be replicated and up-scaled into other dry land counties of Kenya and Sub-Saharan Africa as a possible intervention to improve resilience to climate variability and a strategy for poverty alleviation. At the same time, it cautions on the importance of accounting for heterogeneity of communities that benefit from interventions.

Research Doctorate - Doctor of Philosophy (PhD)

The influence of low-frequency climate variability, as represented by the Inter-decadal Pacific Oscillation (IPO) and Pacific Decadal Oscillation (PDO), collectively known as Pacific Decadal Variability (PDV), has been explored in a wide collection of studies. Statistical characteristics of rainfall and streamflow, changes of drought, flood and bushfire frequencies have been found to be associated with PDV in some regions. PDV runs refer to periods during which a PDV index lies above (or below) some threshold. These alternating runs have been shown to be associated with predominantly dry (or wet) hydrological conditions in some regions. The goal of this thesis was to understand the statistical characteristics of PDV runs and assess the value of incorporating PDV information in urban water supply system decision making. In pursuit of this goal, this thesis had five objectives The first objective was to identify the regions in eastern Australia, both east and west of the Great Divide, where PDV significantly influences rainfall and streamflow. It was shown using relative differences that the Australian Water Availability Project (AWAP) gridded rainfall and streamflow product can produce largely unbiased estimates of PDV influence. Furthermore, this thesis showed that rainfall and streamflow over a large portion of eastern Australian are affected by PDV phases with relative differences in mean streamflow exceeding 50% over much of the study region north of Canberra. These regions can potentially benefit from PDV-informed water supply decision making. The remaining four objectives worked towards defining this benefit. Because of the limited instrumental record, there are many palaeo reconstructions of PDV indices from which PDV runs can be extracted. Using these reconstructions, two fundamental questions of hydrological importance were asked: are PDV wet and dry phases statistically different and have PDV phases been stationary over the last millennium? The results suggest that there is no substantial evidence to support the assumption that run lengths have statistically different distributions during positive and negative PDV phases. Analysis based on three millennium-long reconstructions suggests that it is more likely than not, that the PDV run length has been non-stationarity in the past millennium. PDV palaeo reconstructions are subject to reconstruction errors, both systematic and random. However, understanding the impact of such errors is limited by the fact that “ground truth” is only possible in the period where palaeoclimate and instrumental data overlap. To develop a deeper insight on the role of such errors, synthetic stochastic experiments were designed to simulate the effect on errors on reconstructed PDV indices and PDV runs. The results showed that reconstruction errors cause the PDV run length standard deviation to be overestimated, in some cases very substantially, with the autocorrelation of the errors having the most significant impact on this…

▼ Business processes have facilitated and enhanced management activities, being considered an instrument capable of approximating the strategic guidance and the people who execute their work to achieve organizational goals. In this scenario, continuous evaluation procedures, compliance with government regulations and industry standards, evolutions in the business domain, stakeholders’ needs, new technologies and economic factors related to globalization pressure are examples of aspects that can foster changes on business processes. The impact of this changing environment is the variation of business processes, in a phenomenon called business process variability. The objective of this research is, therefore, to aggregate relevant studies which address the context of this phenomenon. The studies’ selection was accomplished through a Systematic Literature Review, conducting automatic searches in a set of digital libraries and manual searches in leading conferences and journals in the fields of Business Process Management and Computer Science. In total, 13619 studies were retrieved, from which 80 were classified as relevant. This set of primary studies acted as sources of evidence for answering 3 research questions and their respectively subquestions. From the analysis performed, the study concludes that despite efforts in the literature for managing business process variability, this concept is not clear and well delimited, involving additional aspects and, hence, lacking a structured taxonomy. Contributions of the current work are: to provide valuable information with respect to the main notions in business process variability field and, possible types and inductors of process variability;to identify the main challenges faced by organizations when dealing with this phenomenon and; to examine a set of proposals for process variability management, investigating the existence of tool support and empirical evaluations carried out.

▼ This research investigated the physical and economic impact of incorporating tactical responses in risk management strategies in high performance dryland sheep production systems. An existing grazing sheep simulation model was used in the study. The model was extended by incorporating additional pasture, animal and management modules required in line with the objectives. Seven strategies (S) which differed in the pasture mixes utilised (either grass- or legume-based) and stock class utilised as flexibility options (cattle; grass-based system or old ewes; legume-based system), were evaluated at different stocking rates (SR; stock units (SU) per ha (SU ha 1)), with and without tactical adjustments to trigger soil moisture level (SML) in the top 25 cm soil. Strategy 1 simulated a conventional sheep farm with 13 paddocks of perennial grass:clover mix, 2 paddocks in forage crop (kale) and one paddock into lucerne; strategy 2 was similar to 1 but with 25.0% of the ewes replaced with equivalent cattle stock units; strategy 3 was similar 1 but with introduction of a 1st cycle ewe policy; strategy 4 was a combination of strategies 2 and 3; strategy 5 was similar to 3 but with introduction of 2 paddocks of switch pasture and 3 of lucerne; strategy 6 was similar to 4 but with introduction of 2 paddocks of switch pasture and 3 of lucerne; and strategy 7 was similar to 5 but with 5 paddocks of switch pasture and 4 of lucerne. Initially, each of the seven strategies was run at 10, 12, 14 and 16 SR resulting in a 2 factors (7S x 4SR) experiment but without incorporation of tactical adjustments to drop in target SML. In the subsequent analysis, each strategy was re-run with tactical adjustments to the SML target set at 10.0, 12.5 or 15.0% resulting in a 3 factors (7S x 4SR x 3SML) experiment. In general, lambing percentage was consistently higher in strategy 5 for all the SR considered when the opportunities of incorporating tactical responses in risk management strategies were ignored. However, following inclusion of tactical adjustments to climatic variability, the lambing percentage averaged 137.07% across all strategies and SR. Strategy 4 resulted in the highest meat yield and gross margin (GM) but trailed in wool yield. Results obtained in this study show that coefficients of variability (CV) for lambing percentage increased with increase in SR translating to increased risk with increase in SR in high performance dryland sheep systems. All strategies incorporating tactical responses were economically superior to those which did not. In some instances, the difference in GM between corresponding strategies with and without including tactical adjustment to climatic variability was as high as 39.65%. In all cases, corresponding risk management strategies incorporating tactical responses to climatic variability resulted in higher GM (P < 0.05) and lower risk (P < 0.05). The extra income derived from including tactical responses can be viewed as the cost to the farmer of basing choice regarding a management strategy on analysis…

▼ The Kentucky Division of Water indicates that agriculture is responsible for 55% of the Commonwealth’s assessed streams not supporting their designated uses. Riparian buffers reduce nonpoint source pollution in agroecosystems by storing and cycling nutrients, stabilizing streambanks, increasing infiltration, and storing water. Specific information regarding riparian buffer management is needed for land managers to maximize buffer effectiveness at reducing agricultural contaminants impairing water quality. Baseline soil properties (texture, pH, C and nutrients) of the riparian buffer surrounding a tributary of Cane Run Creek in Fayette County, KY were characterized prior to imposing three mowing regimes (intense, moderate, and no mow treatments) and one native grass regime. Measurements were made along parallel transects located 2-m and 8-m distances from the stream. Root biomass, aggregate distribution, and saturated hydraulic conductivity were measured along the 2-m transect in two consecutive years following treatment establishment. The 2-m transect soils had the highest C, pH, Ca, Zn, and sand content. The 8-m transect had the highest P, K, Mg, and clay content. Semivariogram analysis of C content indicated slight to moderate spatial dependency along the 2m transect and moderate to strong spatial dependency along the 8m transect. Root biomass increased with decreased mowing frequency at the surface depth after one year; the native grass treatment had significantly less root biomass in both years compared to mowing treatments. There was no significant treatment effect on aggregate size distribution at the surface depth in either year. Mean weight diameter and large macroaggregates decreased from 2011 to 2012. Vegetation treatment had no statistically significant effect on water stable aggregates or saturated hydraulic conductivity. Experimental semivariograms provided evidence of spatial structure at multiple scales in root biomass, aggregates, and soil C. Spatial variability occurred over a shorter lag distance in 2012 than 2011, suggesting an effect of imposed treatments slowly developing over time. This study provides important insights on riparian buffer soil properties, soil sampling strategies to detect spatial variability in riparian buffers, and length of time needed to assess effects of vegetation management regimes on riparian root biomass, soil aggregates, and hydraulic conductivity.

A irrigação tem a função de suprir adequadamente as demandas hídricas das culturas, para que estas expressem seu máximo potencial produtivo. Porém ocorrem variações no que diz respeito à relação solo, planta, atmosfera, que inferem de maneira a determinar diferenças nas produtividades das culturas, portanto, a utilização de tecnologias e equipamentos é fundamental para um bom manejo da irrigação. O objetivo deste trabalho foi de avaliar a viabilidade de implementação de um sistema com irrigação tipo pivô central na cultura da soja (Glycine max (L.) Merrill.) com o auxílio do irrigâmetro, e comparando o seu desempenho com o tanque classe A. O presente trabalho foi desenvolvido na Granja Boligom situada no município de Bossoroca RS, em uma área experimental de 31,17ha no período de janeiro a junho de 2010. A área experimental foi dividida em sete setores de aproximadamente 4,5 ha. A coleta das plantas foi realizada controladamente, dentro de cada setor, sendo coletadas vinte e cinco plantas, sempre as mesmas, para avaliar o seu desenvolvimento vegetativo e os componentes de produção. Foram medidos os parâmetros de crescimento e desenvolvimento, tais como, índice de área foliar (IAF) e altura de plantas em períodos quinzenais. Na colheita foram determinados os componentes de produção como número de plantas.m, número de vagens.planta-1, número de grãos.vagens-1, peso médio do grão, massa seca dos grãos.planta-1, massa seca do colmo.planta-1, massa seca das vagens.planta-1, massa seca total, índice de colheita e produção (kg.ha-1). O manejo de irrigação foi realizado com turno de rega estipulado pelo irrigâmetro. A lâmina de água foi aplicada igualitariamente em todos os setores, sendo esta realizada através do controle do irrigâmetro. Os arquivos com os pontos da área georreferenciada foram visualizados através de software ArcGIS versão 9.3, onde mapas de produtividade foram gerados por interpolação. As médias de produção dos diferentes setores foram submetidas à análise de variância e pelo teste de Tukey a 5% de probabilidade de erro. Conclui-se que houve diferença de lâminas de irrigação entre o irrigâmetro e tanque classe A, ocorreu variação na produção entre os setores, onde o setor 03 obteve a maior produção com 6713,25 kg.ha-1 e o setor 05 a menor com 5248,05 kg.ha-1.

▼ Best management practices (BMPs) aim to reduce bacterial loading caused by grazing cattle. Relatively little is known about the effectiveness of alternative shade, alternative water, rip-rap, and prescribed grazing as potential BMPs. Prescribed grazing evaluated how stocking rate affected bacterial loading. E. coli concentrations in runoff samples were compared between plots with various stocking rates. GPS collars were used to determine how a shade pavilion, water source, or rip-rap effected cattle distribution within a stream and riparian pasture by comparing time cattle spent at a location before and after implementing the BMPs. While plots were stocked or within 14 days of being destocked, E. coli concentrations were significantly higher than destocked pastures. No significant differences were observed between E. coli concentrations in runoff from heavily stocked, moderately stocked, or non-grazed pastures when pastures had been destocked for greater than 14 days. On average, the shade structure reduced cattle's dependence on riparian shade by 30%. The alternative water BMP did not reduce the amount of time cattle spent within the riparian zone; however, the study was limited to one trial. Riparian rip-rap trials were inconclusive; however, preliminary rip-rap trials showed 20 to 40 cm diameter rip-rap was effective at modifying cattle trough preference. Advances in microbial source tracking, specifically Bacteroides, have allowed better identification of bacterial sources. However, genetic variability within some Bacteroides sequences may undermine the accuracy of these molecular markers. Localized gene-copy curves were created from 12 bovine fecal samples from a single herd, and qPCR assays were used to determine if they better correlated Bacteroides and E. coli populations. Sequences were pyro-sequenced to see if mismatches occurred within primer/probe regions. Base-pair mismatches occurred, and affected qPCR efficiencies. Fecal pollution load estimations were overestimated by using sequences with more mismatches. Genetic diversity was observed within samples from all locations, and indicated genetic variability within Bacteroides populations occurs within a single location as much as between locations. Thus, creating standard curves for individual watersheds would not necessarily improve pollution load estimations.

▼ This research suggests two categories of carbon management methods to help control and reduce net CO2 emissions: increasing the efficiency of energy processes to reduce CO2 production and utilizing processes after CO2 production to reduce the amount of emission. Second chapter analyzes the use of remotely controllable household water heaters as a technique that can reduce the variability cost of wind power in the system. Produced wind power is variable and integrating large scale wind power with power system needs backup facility to keep the system reliable. Thus, variability of wind power imposes cost on the system which is called variability cost. Using a computational model, this research simulates a system of three elements: wind farm, household water heaters and grid (as power system) and suggests that using controllable water heaters as demand side management policy can help reducing variability cost of entire system. This chapter analyzes and compares three scenarios to show the effect of distributed thermal storage on variability of wind power. Third chapter develops a techno-economic model for assessment of industrial CO2 storage in Shale gas reservoirs. CO2 storage in underground deep formations can be a long-term efficient way for carbon management. In this method, CO2 needs to be captured from emitter (industrial plant), pressurized, transported with pipeline and then injected to the reservoir. CO2 sequestration for Enhanced Gas Recovery is technically feasible but its economic feasibility depends on many factors. This research has developed a techno-economic model, integrated with a reservoir simulation tool (SRM), to analyze costs associated with CO2 sequestration in Shale gas. Cost structure in techno-economic model has four parts (modules): Transportation, Injection, Production, and Post-Injection Site Care. Each module generates individual results and also contributes with other modules in producing overall results. Various scenarios defined and tested with the model to give a better understanding about sensitivity and importance of input parameters. Fourth chapter utilizes the upgraded version of techno-economic model to run stochastic, uncertainty, and sensitivity analysis. This chapter also studies the production and injection timing under uncertainty to find more efficient results. In addition to results in third chapter, subsurface and economic parameters have substantial impact on costs and revenue. Reservoir properties along with well characteristics determine CH4 production, CO2 injection, storage capacity, possible CO2 breakthrough in production and so on. Upgraded model has the capability of studying sensitivity of each single geologic property individually or any combination of them. Forth chapter will study the impact of influential variables to explore the sensitivity of outputs to major inputs.

▼ The conservation community is increasingly focused on managing nature explicitly for ecosystem services that provide benefits to humans, rather than for its intrinsic value. Though often debated, the consequences of conserving ecosystems for their services rather than for the explicit goal of biodiversity protection are not clear. While biodiversity can contribute to ecosystem services, this scientific link is fraught with uncertainty. How many and which species to protect is thus an important challenge for applied and theoretical environmental science, as well as new policy initiatives, such as the intergovernmental platform on biodiversity and ecosystem services (IPBES). My first chapter presents new theory to address the extent to which a goal of ecosystem service provision creates a significant economic incentive for biodiversity protection when facing uncertainty over how biodiversity produces services. I derive the level of biodiversity protection that maximizes ecosystem service provision under uncertainty and define a criterion that can be used to determine when managing for ecosystem services economically justifies broad-scale biodiversity protection. I illustrate the utility of this criterion, applying it to several ecosystem services across locations (pollination, wave attenuation, and carbon storage). Next my second chapter considers factors other than uncertainty that may increase alignment between management to obtain ecosystem services versus explicitly to conserve biodiversity. I find the objectives of conserving biodiversity and delivering ecosystem services align more frequently than would be predicted by considering only the known and direct contributions of abundant species to current ecosystem service provisioning. Specifically, I review existing literature on four factors that strengthen alignment, finding the following. First, the number of species that contribute significantly to services is much larger than many current estimates from observational studies. Second, coarse management actions to enhance ecosystem services, such as protecting a location or restoring a habitat type, can provide “incidental” conservation benefits at no additional cost. Third, managing for services should provide broader benefits to biodiversity by disproportionately protecting at-risk species if the species most at risk of local extirpation also contribute significantly to one or more services (i.e., rare or threatened species). Fourth, managing for even a single, relatively low value ecosystem service can have indirect benefits to biodiversity if the species that are significant to service provision have functional ecosystem roles that promote biodiversity (e.g., if they are habitat forming species or keystone predators). However, significant uncertainty remains, especially surrounding the service provisioning roles of the vast number of rare species in nearly every ecosystem. Finally, in my third chapter, I aim to reduce uncertainty about the role of biodiversity in the provision of a…

▼ Despite the extensive deployment of smart-meters (SMs) at the low-voltage (LV) level, which are either fully operational or will be in the near future, distribution network operators (DNOs) are still relying on a limited number of permanently installed monitoring devices at primary and secondary medium-voltage (MV) substations, for purposes of network operation and control, as well as to inform and facilitate trading interactions between generators, distributors and suppliers. Accordingly, improved and sufficiently developed models for the analysis of aggregate demands at the MV-level are required for the correct assessment of load variability, composition and time-dependent evolution, necessary for: addressing issues of robustness, security and reliability; accomplishing higher penetration levels from renewable/distributed generation; implementing demand-side-management (DSM) schemes and incorporating new technologies; decreasing environmental and economic costs and aiding towards the realisation of automated and proactive ''smart-grid'' networks. The analysis of MV-demand measurements provides an independent source of information that can capture network characteristics that do not manifest in the data collected at the LV-level, or when such data is restricted or altogether unavailable. This information describes the supply/demand interactions at the mid-level between high-voltage (HV) transmission and LV end-user consumption and opens possibilities for validation of existing bottom-up aggregation approaches, while addressing issues of reliance on survey-based data for technical and economic power system studies. This thesis presents improved and novel methodologies for the analysis of aggregate demands, measured at MV-substations, aimed at more accurate and detailed load profiling, temporal decomposition and identification of the drivers of demand variability, classification of grid-supply- points (GSPs) according to consumption patterns, disaggregation with respect to customer-classes and load-types and load forecasting. The developed models are based on a number of traditional and modern analytical and statistical techniques, including: data mining, correlational and regression analysis, Fourier analysis, clustering and pattern recognition, etc. The approaches are demonstrated on demand datasets from UK and European based DNOs, thus providing specific information for the demand characteristics, the dependencies to external parameters and to socio-behavioural factors and the most likely load composition at the corresponding geographical locations, while the approaches are also intendent to be easily adaptable for studies at equivalent voltage and demand aggregation levels.

▼ [EN] Model-Driven Development (MDD) promotes models as the cornerstone in the software development process, thereby displacing source code as the development process's main feature. Although this model-centric schema claims advantages over traditional software development (e.g., the code could be automatically generated from the models), it does not have the level of adoption that has been expected. The literature review reveals a broad agreement in the fact that end-users may develop and adapt systems themselves but the complexity in modeling standards and the lack of modeling skills prevents their active involvement in modeling tasks of existing MDD processes. To overcome this, end-users should be provided with different modeling languages that use concepts, which fit their particular skills, context and needs. This challenge is the main goal of this thesis, which is addressed by combining the End-user Development and the Model-Driven Development fields. This work starts with the involvement of end-users into the modeling tasks using a tool-supported visual modeling language that allows end-users to select and customize system features of pervasive systems using closer concepts for them. Afterwards, this thesis shows the necessity of enriching existing MDD processes for supporting the development of a new generation of software systems (e.g., smart health) that require expertise in a variety of domains. Consequently, different types of users (e.g., scientists, engineers and end-users) must actively participate in the description of model fragments that depend on their expertise using a different modeling language. Thus, users are able to collaborate to obtain a unified system description. At this point, it becomes necessary to provide mechanisms that transforms models fragments from one modeling language to another, delimits which model fragments are described by a different user, and integrates those model fragments. To provide this, the presented approach encompasses variability management in a novel way to enable collaborative modeling by supporting both the selection of model fragments of the system that may be described using a different modeling language, and the integration of those model fragments once they are described. Furthermore, interoperability mechanisms bridge two different modeling languages in a non-intrusive way with the structure of models by transforming the description of gaps. Thus, our proposal could enrich models of existing MDD processes with model fragments that have been described using a different modeling language, which could make users feel confident to adopt models for describing domain-specific content and could help to adopt MDD processes. The proposal has been validated in three case studies from different levels of complexity and domains: smart home systems, web information systems, and biomechanical protocols. The results have proven the applicability and feasibility of our approach to actively involve different types of users (end- users with software professionals,… Advisors/Committee Members: Fons Cors, Joan Josep (advisor), Valderas Aranda, Pedro José (advisor).

▼ Agriculture constitutes the largest economic sector and professional occupation in Chad, and is undergoing rapid changes due to processes of population increase, institutional reforms, conflicts in neighbouring countries, increasingly globalized trade networks, and environmental changes. But despite their importance for livelihoods and economic growth, the specific patterns and drivers of change in the agricultural sector are however poorly understood. This has mostly been a result of low data availability and a lack of comprehensive research programs to address the agricultural changes of various spatial scales. By analysing crop statistics on a level of detail that have not been done before, this thesis has been able to show how the agricultural production is changing over time and between the different administrative regions in Chad. In general it found that the harvested area has been increasing faster than the yield, and that a majority of the changes have happened under abrupt rather than gradual changes. By using this detailed understanding of the patterns of change, and by combining numerous kinds of relevant datasets on hydrology, demographics, international aid, market prices, conflicts, and agricultural practices, this thesis has evaluated potential factors of these changes with an extent and detail that have not been done before. This evaluation have showed that variations in hydrological conditions, market prices, and food security conditions can be linked to the variability in crop production. By looking at descriptions of livelihood conditions in agricultural areas, factors such as material and technical farm support have been linked to abrupt changes in the crop production for specific areas. Also, the differences in long term change between the administrative regions in Chad have been explained by differences in demographic factors and amount of international aid received. These and similar results are relevant to increase the understanding of how agricultural societies evolve in Chad, and how strategies and interventions can be developed to assist local communities in their objectives. More specifically, the results can be used to evaluate the effects of certain events or policies, and to improve seasonal predictions for crop production and food availability. Beyond Chad, the results and methods developed for this thesis are relevant for application in the wider Sahel, where the agro-ecological and institutional conditions share some key characteristics.

▼ This dissertation explores the service design antecedents and the performance outcomes of Service Improvisation Competence (Serv-IC) the ability of service employees to deviate from established processes and routines in order to timely respond to unexpected events, using available resources. Service operations and strategy research have strongly highlighted the importance of possessing flexibility in order to face the uncertainty derived from the interaction with the external environment (Tansik and Chase 1988, Eisenhardt and Tabrizi 1995, Brown and Eisenhardt 1998, Frei et al. 1999, Menor et al. 2001, Frei 2006). An important component of the ability of service rms to adapt to customer requests, expectations, and needs rests in the systemic ability of frontline employees to creatively adapt to the challenges posed by the constant struggle to satisfy customers. This dissertation is composed of three essays. In Essay 1, we build the theoretical framework necessary to advance a theory of Service Improvisation Competence, and we propose a nomological network that links service delivery design choices facility design, managerial practices, information distribution, and the procedures that regulate customer-contact to the development of a Service Improvisation Competence (Serv-IC). Furthermore, Essay 1 oers a causal theory of the effects of Serv-IC on service outcomes. Essay 2 builds on the theoretical foundations of Essay 1, as well as on previous empirical and theoretical work (Moorman and Miner 1998b, Weick 1998, Miner et al. 2001, Vera and Crossan 2005), and develops psychometrically sound measures of Service Improvisation Competence, using a survey of frontline hotel employees. In addition, in Essay 2 we operationalize and test a model of antecedents and outcomes of Serv{IC constructed on the theoretical framework proposed in Essay 1, using path analysis. We find that the development of a Service Improvisation Competence is the result of a holistic design process which takes into consideration simultaneously the different design elements presented in Essay 1. Employee empowerment plays a pivotal role in the enactment of a Service Improvisation Competence (Serv-IC), by fully mediating the relationship between strategic design choices and Serv-IC. We also confirm the insights of Mintzberg (1994), and show that an increase in scripting of the service encounter leads to a decrease in improvisation only up to a certain point, after which the increase in scripting becomes counterproductive to the end of standardization, and results in an increase in improvisation. In other words, the intended managerial goal of increasing the degree of scripting (increase in standardization) results in the opposite outcomes (increase in the amount of deviations from scripted behaviors). Essay 3 builds on the results of the previous essays and, applying econometrics methods to a survey of hotel managers, deepens our understanding of the differential effect of Serv-IC on the business… Advisors/Committee Members: Roth, Aleda V, Ozkan , Gulru, Mroz , Thomas A, Verma , Rohit.

As peculiaridades de cada paÃs levam Ã utilizaÃÃo de mecanismos variados de alocaÃÃo de recursos hÃdricos, nÃo havendo uma regra geral para a resoluÃÃo do problema de escassez de Ãgua. O conhecimento dos modelos experimentados internacionalmente, com a identificaÃÃo de suas respectivas vantagens e desvantagens, sÃo de grande utilidade. O objetivo principal da gestÃo dos recursos hÃdricos Ã satisfazer a demanda, considerando as possibilidades e limitaÃÃes da oferta de Ãgua. Entretanto, para isso, Ã necessÃrio o conhecimento de todos os aspectos hidrolÃgicos, climatolÃgicos e fÃsicos da regiÃo para realizar um planejamento adequado de oferta hÃdrica, alÃm do conhecimento da populaÃÃo e dos mÃltiplos interesses, para um bom dimensionamento da demanda. Entretanto, quando o sistema hÃdrico Ã alimentado por influxos espacial e temporalmente variÃveis, que Ã o que ocorre em regiÃes semiÃridas, a escolha de um modelo eficaz de gestÃo dos recursos hÃdricos torna-se ainda mais complexa, devido Ãs incertezas presentes na avaliaÃÃo dos futuros nÃveis de Ãgua. Nestes casos, as incertezas tÃm um importante papel na gestÃo dos recursos hÃdricos. Em busca de um estudo mais profundo da gestÃo dos recursos hÃdricos nessas regiÃes de alta variabilidade climÃtica, foram tomados como anÃlise os modelos aplicados no Nordeste Brasileiro e na AustrÃlia. O presente trabalho apresenta a semelhanÃa nas caracterÃsticas do clima dessas regiÃes, a semelhanÃa nos problemas enfrentados por cada uma delas e, finalmente, traÃa um paralelo, atravÃs da anÃlise e comparaÃÃo dos diferentes mÃtodos de gestÃo dos recursos hÃdricos disponÃveis.

The peculiarities of each country lead to the use of various mechanisms of water allocation. There is no general rule for solving the problem of water scarcity. Understanding the models experienced internationally, identifying their respective advantages and disadvantages are very useful. The main objective of water management is to attend the demand, considering the possibilities and limitations of water supply. However, for this, it is necessary to know all hydrological, climatological and physical aspects of the region to conduct a proper planning of water supply, beyond the knowledge of the population and the multiple interests, to a good demand sizing. However, when the water system is supplied by spatial and temporal variability of inflows, as in semiarid regions, the choice of an effective model for water management becomes more complex, due to the uncertainties presented in evaluating future water levels. In these cases, uncertainties have an important role in water resources management. In the matter of a deep study of water resources management in these regions of high climate variability, models applied in Northeast Brazil and Australia were used as analysis. This paper presents the similarity of climate aspects, the similar problems faced by each region, and finally draws a parallel comparing different methods of available water management.

▼ Agriculture-dependent societies invest in irrigation infrastructure to enhance water security for agricultural production and improve farmers' livelihoods in the face of hydroclimatic risks. While these investments have historically contributed to food security and economic growth, we have an incomplete understanding of their distributional impacts. We lack evidence of the dynamic outcomes of investments in irrigated agriculture in specific contexts with respect to uncertain hydrological cycles, policy impacts, and socio-economic poverty. This thesis addresses this gap by exploring how investments in irrigation infrastructure influence agricultural, poverty, and behavioural outcomes. To do so, it uses a ten-year World Bank funded programme to modernise irrigation infrastructure in the Indian state of Madhya Pradesh (MP) as a case study. The thesis builds upon prior work analysing the relation between infrastructure, water security, and the economy. In particular, it relates to the literature on: (1) the association between hydrological variability, rehabilitated irrigation infrastructure, and crop yields; (2) the distributional impacts of irrigation and links to poverty alleviation through well-being; and (3) the role of infrastructure and financial incentives in driving the irrigation choices of farmers. The overarching research question of the thesis is: do investments to modernise and rehabilitate irrigation infrastructure enhance outcomes related to agricultural water security in Madhya Pradesh? To answer this question, the thesis explores the impact of improved infrastructure by examining changes in crop yields, farmer well-being, and irrigation practices by taking into account contextual factors related to hydrological variability, crop price and subsidy policies, socio-economic characteristics of farmers, and social dynamics among farming communities. The thesis utilises a mixed methods approach combining analysis of rainfall anomalies at the district-scale supported by a cross-sectional survey of 918 farmers and consultations with stakeholders from government, donor, and farming communities. The results advance knowledge of the multiscale and multidimensional consequences of irrigation infrastructure investments with implications for water security. The thesis highlights that in the context of Madhya Pradesh: a) there is a positive correlation between infrastructure and crop yields in average rainfall areas and little to no effect of rehabilitation on yields in low or high rainfall areas after accounting for district-scale hydroclimatic variability; b) national food security policies such as the Minimum Support Price for cereal crops are strongly correlated with crop yields more so than hydrological factors; c) access to modernised surface irrigation is positively correlated with improvements in farmers' well-being, with evidence of higher gains among poorest segments of farming communities and where rainfall is low; d) in areas with improved irrigation canals there is reduced probability that farmers will…

Le processus de conception des BD ne cesse d'augmenter en complexité et d'exiger plus de temps et de ressources afin de contenir la diversité des applications BD. Rappelons qu’il se base essentiellement sur le talent et les connaissances des concepteurs. Ces bases s'avèrent de plus en plus insuffisantes face à la croissante diversité de choix de conception, en soulevant le problème de la fiabilité et de l'exhaustivité de cette connaissance. Ce problème est bien connu sous le nom de la gestion de la variabilité en génie logiciel. S’il existe quelques travaux de gestion de variabilité portant sur les phases physique et conceptuelle, peu se sont intéressés à la phase logique. De plus, ces travaux abordent les phases de conception de manière séparée, ignorant ainsi les différentes interdépendances.Dans cette thèse, nous présentons d'abord la démarche à suivre afin d'adopter la technique des lignes de produits et ce sur l'ensemble du processus de conception afin de (i) considérer les interdépendances entre les phases, (ii) offrir une vision globale au concepteur, et (iii) augmenter l'automatisation. Vu l'étendue de la question, nous procédons par étapes dans la réalisation de cette vision, en consacrant cette thèse à l'étude d'un cas choisi de façon à montrer : (i) l'importance de la variabilité de la conception logique, (ii) comment la gérer en offrant aux concepteurs l'exhaustivité des choix, et la fiabilité de la sélection, (iii) son impact sur la conception physique (gestion multiphase),(iv) l'évaluation de la conception logique, et de l'impact de la variabilité logique sur la conception physique (sélection des vues matérialisées) en termes des besoins non fonctionnel(s) :temps d'exécution, consommation d'énergie voire l'espace de stockage.

The evolution of computer technology has strongly impacted the database design process which is henceforth requiring more time and resources to encompass the diversity of DB applications.Note that designers rely on their talent and knowledge, which have proven insufficient to face the increasing diversity of design choices, raising the problem of the reliability and completeness of this knowledge. This problem is well known as variability management in software engineering. While there exist some works on managing variability of physical and conceptual phases, very few have focused on logical design. Moreover, these works focus on design phases separately, thus ignore the different interdependencies. In this thesis, we first present a methodology to manage the variability of the whole DB design process using the technique of software product lines, so that (i)interdependencies between design phases can be considered, (ii) a holistic vision is provided to the designer and (iii) process automation is increased. Given the scope of the study, we proceed step-bystepin implementing this vision, by studying a case that shows: (i) the importance of logical design variability (iii) its impact on physical design (multi-phase management), (iv) the evaluation of logical design, and the…

▼ The challenges of demand order management on the underlying Just in Time (JIT) approach need a long-term solution in order to reduce expenses and enhance supply chain performance. Demand management is a very important aspect of managing one’s organisation, especially in the presence of a volatile environment, full of competitors, global pressures and sustainability requirements. Thus, organisations are placed in a position where it has become necessary to implement strategies such as the JIT approach to meet demand with minimal resources and costs. Poor demand management decisions taken in forecasting therefore increase business risk and costs. The study aims to establish the effect of information sharing and collaborative forecasting within an organisation. The demand alignment may pose some problems leading to inefficiency in customer service, poor stock rotation and a high obsolescence rate aggravated by the diversity of products. Demand management sought the rapid and appropriate integration of the needs arising from the market in the direction of the suppliers in order to balance and strategically align demand with operational capacity along the supply chain. However, the concept of demand management is not yet understood by supply chain agents as the major cause of failure is accredited to not achieving chain coordination due to the poor understanding of demand leading to inadequate customer service, poor stock rotation and large obsolescence rates. The main aspects underpinning this study are: demand management; JIT; order fulfilment; information sharing; order synchronisation; and demand order variability and flexibility, and forecasting. The objectives of the study are: to determine the challenges of dynamic demand management under the JIT order fulfilment system; to establish the effects of information sharing and collaborative forecasting for efficient operational demand management; to explore the extent of demand order variability and flexibility on the underlying JIT system; and to analyse the role of order synchronisation fulfilment to facilitate the balanced alignment of demand and supply order management. The nature of this study suggests the use of an exploratory case study design to explore the dynamics of demand management with the JIT system employed by the organisation under study. A qualitative research approach was used in this study as it added more value when determining the issues faced in the organisation. The study was conducted in KwaZulu-Natal at the Durban head office. The sampling type employed was purposive sampling. The total sample size is three. Face-to-face semi-structured interviews were used as a means of data collection. Thematic analysis was used to analyse data in the primary qualitative research in this study. The findings of this study suggest that communication and real-time data are matters of concern. These factors contribute to the poor demand management in the organisation. The results indicate that improvements in these aspects are imperative to the success of… Advisors/Committee Members: Mbhele, Thokozani Patmond. (advisor).

▼ There has been an increasing interest in and need for the application of climate information to address societal issues. Partially arising from the increasing confidence in anthropogenic climate change (Stocker et al. 2013) and partially from increasingly complex and resource-limited conditions, climate impacts are now considered in fields as diverse as natural hazards, public health, and agriculture. This research looks to show the utility of existing data analysis and statistical tools in providing actionable information to decision makers. Though this information is relevant in a wide variety of locations and conditions, the focus of this research has been on producing information for applications in the developing world. Climate variability at multiple timescales can have an outsized impact in the developing world given the often limited infrastructure, and weaker social and economic institutions (Field et al. 2014). There is a need for tools and analyses that translate climate information at coarse space and time scales to local scales where decisions of resource management are made. Through climate diagnostics, precipitation associated with the West African and East African monsoons show variations both subseasonally and interseasonally over the 20th and early 21st centuries. While prominent events including a wet period in the middle of the 20th century and a drought in the late 20th century have been well documented, this research highlights how this interseasonal variability can be linked to changes in large-scale teleconnections. In examining these teleconnections this research also notes that these teleconnections have entered into a new epoch. Tools that translate this information to address local issues have been developed. In West Africa, a stochastic weather generator can simulate the weather variables required to assess livestock heat stress and offer a means of forecasting and spatial modeling. This information can provide pastoralists better information during their seasonal migration. In East Africa, an understanding of precipitation variability and its coupling with the Madden-Julian Oscillation can be used to improve the sub-seasonal to seasonal forecasts of precipitation which can be used to improve water management.

▼ The severe and sustained nature of the recent drought in the southwestern United States, coupled with a growing collection of scientific literature indicating that anthropogenic climate change will further dry the region, have raised considerable concern about the reliability of its water resources. Undoubtedly, climate change poses a significant threat to water supplies in the Southwest. However, relative to this long-term shift in basin yield, natural variability is likely to be the key driver of supply risk over, say, a 20 year horizon. Hence, the focus of this work is on the development of tools and strategies to address streamflow variability, at the decadal time scale, with application for improved water management in the Colorado River Basin. Streamflow simulation and disaggregation methods are first presented. These novel techniques offer the ability to simulate multi-site data at a variety of time scales – including daily, while also preserving non-stationary spectral properties seen in historic data. An analysis of Colorado River flow variability follows. Here, physical mechanisms are established for significant variability modes, and subsequently, links with large scale climate phenomena are proposed. Based on insight gained from the aforementioned work, a technique for decadal flow regime projections in the Colorado River Basin was established. The approach is demonstrated on paleo reconstructed data and then used to make actual future projections. Last, the Bureau of Reclamation Colorado River long-term planning model (CRSS) is used to assess adaptive operational policies. The objective is to improve Basin-wide supply reliability under various potential future hydrologic conditions, including climate change scenarios derived from downscaled general circulation model output. These policies were developed to reduce system losses and capitalize on information provided by flow regime projections. Results show that under the variety of hydrologic conditions notable savings are seen, which help to reduce overall system risk of shortage conditions.

▼ The number and complexity of the systems realizing the functionality of the machines in the automotive domain are growing. In this arises the need for a systematic way to manage their development. As the technologies advance, the vehicles introduce an increasing range of capabilities. However, they have similar functions, which have the potential to be reused. One of the widely used approaches that manages the commonality and variability of the development artifacts in a systematic manner is Product Line Engineering (PLE). Consequently, PLE reduces the time to market and the development cost. The machines, realized in the automotive domain, interact with their operators and the surrounding environment. Possible malfunctions of the machines may introduce a risk of accidents with fatal consequences. Therefore, the products should be analyzed, developed and managed in a safe manner and certified according to different relevant safety standards like ISO 15998, ISO 61508 and ISO 26262. There is a diversity of functions in a Product Line (PL). Some of them are mandatory for all machines and others are optional for some models. This gives the opportunity to combine the functions in multiple configurations. However, not all combinations are possible due to dependencies among the functions. Furthermore, the configurations should be valid from a safety perspective, and the developed products should satisfy the requirements identified during the safety analysis. The above mentioned factors emphasize the need for explicit representation of the systems' characteristics, such as commonality and variability, functional dependencies and quality attributes. The purpose of the current work is to find an efficient way to satisfy this need. The scope of our research is limited to the automotive domain. In order to gain familiarity with the state of practice, we collaborated with Volvo Construction Equipment (Volvo CE) as an industrial partner. In particular, we: conducted an informal interview study with the practitioners,analyzed the requirements management tool used in Volvo CE and studied products typical for the domain in detail,examined the deliverables defined in the related domain specific safety standards. We gained knowledge on how variability is managed in an industrial context today, which safety aspects need to be considered and how functional safety artifacts are managed with regards to variability. We synthesized the characteristics that are explicitly represented during the development and safety certification of the products in a safety-critical product line. We identified the challenges that the practitioners meet today and the areas that need to be improved. As a result, we formulated evaluation criteria for search and assessment of possible solutions. Subsequently we searched in the literature for different modeling techniques, that are able to respond to the industrial needs, and found the following to be relevant in our…

▼ Pacific salmon (Oncorhynchus spp.) production strongly influences the ecosystems, cultures and economies of the Northeast Pacific. Historical variability in population sizes is complex, reflecting natural and human drivers. The nature and extent of such ‘exogenous’ controls on salmon and their nursery ecosystems are poorly understood, a significant impediment to sustainable fisheries management. Novel applications of paleolimnology demonstrate that past sockeye salmon abundances and nursery system ecology can be reconstructed from lake sediments. This thesis focuses on employing these techniques to establish the forcing mechanisms underlying salmon population and ecosystem dynamics, and determine the effects and interactions of fisheries management. I provided the first reconstruction for a southern North American stock, which demonstrated the influences of both conspicuous (e.g. commercial fishery, main-stem damming) and uncertain human impacts (e.g. local damming) on endangered salmon declines. By reconstructing ecological variability at multiple trophic levels, I established that rehabilitative management (e.g. fish stocking) may have permanently altered nursery lake rearing capacity, a change potentially reinforced by recent atmospheric changes. This work highlights significant impediments to ongoing recovery efforts. I extended my analysis of salmon management by exploring the interactive impacts of exotic salmon stocking on a remote northern lake. I demonstrated the utility of long-term data in pre-emptively understanding the complex impacts of stocking by documenting the long-term trajectories in limnological conditions. Integrating modeling, limnological and paleolimnological analyses, I determined that climate change and salmon introductions compound to alter chemical, physical and biological lake variables, ultimately altering ecosystem structure and functioning. Finally I reconstructed salmon abundances over the past six millennia, the longest record and the first Canadian example to date, demonstrating salmon production is cyclical and far more variable than observed in the monitoring record. My analyses established that North Pacific salmon production is forced by ocean-atmospheric teleconnections ultimately linked to climatic variability in the tropical Pacific. Further analyses provided the first evidence for a possible solar forcing of Holocene salmon production on both orbital and higher frequency time scales. Cumulatively this research improves our understanding of the processes underlying variability in Pacific salmon and their natal ecosystems, important to ecologically-informed future management.
