There is limited research on the use of results-based management (RBM) in schools, therefore this study focussed on developing a sustainable and effective RBM model. The objectives of the study were to identify the obstacles encountered in implementing RBM in primary and secondary schools in the Goromonzi District, identify and describe the steps taken in developing and sustaining an effective RBM model, and to develop a sustainable and effective RBM model suitable for both Zimbabwean primary and secondary schools. A qualitative research method was used since the researcher’s interest was to gain insight into and understanding of school heads’ and teachers’ perceptions, concerns and experiences in their real world conditions when implementing RBM. The study covered ten purposely selected schools in the Goromonzi District. Semi-structured individual and focus group interviews were conducted with the school heads and teachers. To enhance the validity of the findings, this study adhered to ethical principles and techniques. The following salient findings that emerged from the study were that the school heads and teachers had a negative perception of IRBM because a top-down approach was used when it was introduced and the system was not customised since it was merely “imported” from a developed country whose context was different from the Zimbabwean socio-political and economic environment. There was also a serious dearth of financial resources to support the system and this affected the quality of RBM training negatively. The lack of funding also led to the non-payment of incentives for the staff with regard to implementing RBM. It was also indicated that the senior Ministry of Primary and Secondary Education officials showed a lack of commitment and support for RBM. To address the implementation challenges it was indicated that resources had to be mobilised to ensure the capacitation of school heads and teachers and also for incentivising them. Incentivising staff is critical for the successful implementation of RBM. It was also noted that there was a need to develop a results culture in schools and train school heads in change management. It was concluded that a home grown RBM model that was context sensitive to the Zimbabwean situation was required. As envisaged, the study resulted in the development of the three phased Zimbabwe results-based management practical model (ZRBMPM). The first phase addresses RBM implementing challenges and the second phase focusses on incentivising staff to promote the effective implementation of results management. The last phase entails the production of the results. / Educational Leadership and Management / D. Ed. (Education Management)

Using a purpose of collecting evidences that helped the comprehension of the focused process, the study hás analyzed three free software development projects from different characteristics and sizes. The study was guided by a theoretical-empirical approach, which beyond the literature review, looked forward to verify the coherence with the reality to create a knowledge base for the cooperated project model construction. The research was bases on structured interviews, using a pre-defined questionnaire and the result interpretation that was made with the analysis of the subjects behavior, systematically collected and revalued during the investigation process. The research results helped to build an applicable management model for this type of projects, thus new studies are suggested to supply adequate technical base for its implantation / As organizações estão vivenciando um momento de profundas transformações sociais e econômicas, proporcionadas principalmente pela possibilidade cooperação baseada nas tecnologias de informação e comunicação. Neste cenário, esta pesquisa tem como objetivo a criação de um modelo conceitual para gestão de projetos cooperados através do estudo de projetos em rede baseados no desenvolvimento de software livre. Com a finalidade de coletar fontes de evidência que auxiliassem na compreensão do processo focalizado, o estudo analisou três projetos de desenvolvimento de software livre de diferentes características e portes. A pesquisa utilizou uma abordagem empírica e teórica, na qual além da revisão de literatura sobre o assunto, procurou-se verificar a coerência com a realidade, para conceber um conjunto de informações que servissem de referência para a construção do modelo de gestão de projetos cooperados. O trabalho de pesquisa foi apoiado por entrevistas estruturadas, realizadas a partir de um questionário pré-definido e a interpretação dos resultados foi realizada na percepção dos significados dos comportamentos dos sujeitos, coletados sistematicamente e reavaliados durante todo o processo de investigação. Os resultados de pesquisa auxiliaram para construir um modelo de gestão aplicável a este tipo de projetos e desta forma sugerem-se novos estudos que aprofundem o tema, e que forneçam a base técnica adequada para sua implantação

As organizações desenvolveram recentemente novas práticas de gerenciamento de projetos, ditas ágeis e que convivem com as práticas anteriores, ditas direcionadas ao plano (Plan-driven). Ao invés de optar entre uma ou outra, vem ganhando força a ideia de combiná-las. Entretanto, a singularidade dos projetos torna difícil identificar a combinação de práticas mais apropriadas a cada caso. A presente pesquisa propõe uma ferramenta de configuração que relaciona as características e contexto de um projeto com práticas gerenciais, fundamentada em uma matriz morfológica e cujo propósito é apoiar a escolha de práticas e configuração de um modelo de gestão específico para o projeto. O estudo restringiu-se ao planejamento e controle do escopo e tempo em gerenciamento de projetos. A pesquisa iniciou com uma revisão bibliográfica sistemática para identificar ferramentas similares e modelos híbridos disponíveis na área de gerenciamento de projetos. Em seguida, compreendeu uma fase de proposição teórica da ferramenta e seu teste por meio de um estudo de caso em uma empresa de desenvolvimento de softwares, envolvendo desenvolvedores e gestores de projetos com experiência em gerenciamento ágil. A aplicação da ferramenta resultou em propostas diferentes para situações de projetos distintas. Uma análise das justificativas dos profissionais para as suas escolhas, mostrou que as experiências dos profissionais da organização, bem como suas preferências pessoais, influenciam as escolhas e não apenas o contexto do projeto. Há, portanto, indícios de que é viável optar por uma personalização para cada projeto, mas é importante investigar a experiência prévia e preferências dos profissionais de forma a aprimorar a ferramenta. A ferramenta proposta pode servir como referência para as empresas que desejam adequar modelos de gestão para seus diferentes tipos de projetos, combinando as práticas das diferentes abordagens de gerenciamento. O estudo também agrega ao desenvolvimento do tema de gestão hibrida na área de gerenciamento de projetos, trazendo uma inovação em relação as propostas encontradas na literatura. / Organizations have recently developed new project management practices, called agile and coexisting with previous practices, called Plan-driven. Instead of choosing between one and the other, the idea of combining them is gaining strength. However, the uniqueness of the projects makes it difficult to identify the most appropriate combination of practices to each case. The present research proposes a configuration tool that relates the characteristics and context of a project with management practices, based on a morphological matrix, and whose purpose is to support the choice of practices and configuration of a specific management model for the project. The study was limited to the planning and control of the scope and time in project management. The research began with a systematic literature review to identify similar tools and hybrid models available in the project management area. Then, it comprised a theoretical proposition phase of the tool and its test through the case study method in a software development company, involving developers and project managers with experience in agile management. The application of the tool resulted in different proposals for different project situations. An analysis of the professionals\' justifications for their choices showed that the experiences of the organization\'s professionals, as well as their personal preferences, influence the choices and not just the context of the project. There are, therefore, indications that it is feasible to choose a customization for each project, but it is important to investigate the previous experience and preferences of the professionals in order to improve the tool. The proposed tool can serve as a reference for companies that want to adapt management models to their different types of projects, combining the practices of the different management approaches. The study also adds to the development of hybrid management topic in the project management area, bringing an innovation in relation to the proposals found in the literature.

However, the recovery of the third type of waste, comprising the reject, is rare or, in the most of cases, non-existent. Recent studies show that domiciliary solid reject (DR), hospital solid reject (HR) and those from surveillance of illicit drug trafficking can be used in pyrolysis processes to obtain value-added co-products. In this context, this search presents the potential of generation of DR, HR e and those from surveillance of illicit drug trafficking in the 50 municipalities of the western Paraná mesoregion and proposes new management models aimed at their sustainable recovery. Therefore, the generating sources of the rejects were characterized and a prospective survey was conducted, whose quantitative values were obtained from correlations that depend on different variables, being the ones: the urban population and the number of hospital bed of each municipality; and the balance of drug carried out by the Superintendency of the Federal Police of Foz do Iguaçu in the period of 2011 to 2014. Through the assessment of current reject management models and the use of thematic maps, a subdivision of the municipalities in five HD and HR management regions is proposed. In each region, an anchor municipality would receive the installation of an DR screening and processing center and an HR processing center. Thus, the DR processing plant installed in the city of São Miguel do Iguaçu would be responsible for processing 17,60 tons per day; in Campo Bonito 15,58 tons per day; in Marechal Cândido Rondon 12,29 tons per day; in Iracema do Oeste 4,29 tons per day; and in Céu Azul 3,11 tons per day. The HR processing plant installed in the city of Campo Bonito would be responsible for processing 0.90 tons per day; in Marechal Cândido Rondon 0.75 tons per day; in São Miguel do Iguaçu 0.64 tons per day; in Iracema do Oeste 0.22 tons per day; and in Céu Azul 0.19 tons per day. For the management of reject from surveillance of illicit drug trafficking the search proposes the installation of a processing plant in the city of Foz do Iguaçu, with daily processing capacity of 0.10 tons per day. From this perspective, the rejects in study would be converted into raw material and the products of its recovery would return to the production cycle, generating economic, social and environmental positives impacts. / Técnicas de aproveitamento já vêm sendo empregadas para os resíduos sólidos do tipo orgânico e reciclável. No entanto, o aproveitamento do terceiro tipo de resíduo, composto pelo rejeito, é raro ou na maioria dos casos inexistente. Pesquisas recentes mostram que os rejeitos do tipo domiciliar (RD), hospitalar (RH) e aqueles provenientes da fiscalização do tráfico ilícito de drogas podem ser utilizados em processos pirolíticos para a obtenção de co-produtos de valor agregado. Nesse contexto, o trabalho apresenta o potencial de geração de RD, RH e aqueles provenientes da fiscalização do tráfico ilícito de drogas nos 50 municípios da mesorregião Oeste do Estado do Paraná e propõe novos modelos de gestão voltados ao seu aproveitamento sustentável. Para tanto, caracterizou-se as fontes geradoras dos rejeitos em estudo e conduziu-se uma pesquisa prospectiva, cujos valores quantitativos foram obtidos a partir de correlações que dependem de diferentes variáveis, sendo as principais delas: a população urbana e número de leitos disponíveis em cada município; e o balanço de apreensões de drogas realizadas pela Superintendência da Polícia Federal de Foz do Iguaçu no período de 2011 à 2014. Por meio da avaliação dos atuais modelos gestão dos rejeitos em estudo e da utilização de mapas temáticos, propõe-se uma subdivisão dos municípios em cinco regiões de gestão de RD e RH. Em cada região, um município âncora receberia a instalação de um centro de triagem e processamento de RD e um centro de processamento de RH. Assim, a usina de processamento de RD instalada no município de São Miguel do Iguaçu seria responsável pelo processamento diário de 17,60 t/dia; a de Campo Bonito 15,58 t/dia; a de Marechal Cândido Rondon 12,29 t/dia; a de Iracema do Oeste 4,29 t/dia; e a de Céu Azul 3,11 t/dia. A usina de processamento de RH instalada no município de Campo Bonito seria responsável pelo processamento diário de 0,90 t/dia; a de Marechal Cândido Rondon 0,75 t/dia; São Miguel do Iguaçu 0,64 t/dia; a de Iracema do Oeste 0,22 t/dia; e a de Céu Azul 0,19 t/dia. Para a gestão do rejeito proveniente da fiscalização do tráfico ilícito de drogas propõe-se a instalação de uma usina de processamento no município de Foz do Iguaçu, com capacidade de processamento diário de 0,10 t/dia. Sob a ótica dos modelos propostos, os rejeitos em estudo seriam convertidos em matéria-prima e os produtos do seu aproveitamento retornariam ao clico de produtos, gerando impactos econômicos, sociais e ambientais positivos.

The study employed a quantitative research method, which is descriptive in nature, to determine the role of Human Resource Management in supporting the strategic objectives of the Department of Environmental Affairs. This interest was explored with particular reference to the Environmental Programmes branch of the Department of Environmental Affairs. Data was gathered from senior, middle and junior managers through self-administered questionnaires and it was then analysed using statistical methods and graphs. The findings reveal that the role of Human Resource Management in supporting the strategic objectives of the Department of Environmental Affairs is not efficiently elevated or viewed to have any influence on the desired goals of the Department of Environmental Affairs. As a result, the Human Resource Management component is not considered a strategic partner. Furthermore, the senior, middle and junior managers know very little about the Human Resource Management strategy and there exists a lack of emphasis on the development and implementation of joint strategic human resource management plans between the managers and the Human Resource Management component. / Public Administration / M.P.A.

Increasing global mean temperature or global warming has the potential to affect the hydrologic cycle. In the 21st century, according to the UN Intergovernmental Panel on Climate Change (IPCC), alterations in the frequency and magnitude of high intensity rainfall events are very likely. Increasing trend of urbanization across the globe is also noticeable, simultaneously. These changes will have a great impact on water infrastructure as well as environment in urban areas. One of the impacts may be the increase in frequency and extent of flooding. India, in the recent years, has witnessed a number of urban floods that have resulted in huge economic losses, an instance being the flooding of Mumbai in July, 2005. To prevent catastrophic damages due to floods, it has become increasingly important to understand the likely changes in extreme rainfall in future, its effect on the urban drainage system, and the measures that can be taken to prevent or reduce the damage due to floods. Reliable estimation of future design rainfall intensity accounting for uncertainties due to climate change is an important research issue. In this context, rainfall intensity-duration-frequency (IDF) relationships are one of the most extensively used hydrologic tools in planning, design and operation of various drainage related infrastructures in urban areas. There is, thus, a need for a study that investigates the potential effects of climate change on IDF relationships. The main aim of the research reported in this thesis is to investigate the effect of climate change on Intensity-Duration-Frequency relationship in an urban area. The rainfall in Bangalore City is used as a case study to demonstrate the applications of the methodologies developed in the research Ahead of studying the future changes, it is essential to investigate the signature of changes in the observed hydrological and climatological data series. Initially, the yearly mean temperature records are studied to find out the signature of global warming. It is observed that the temperature of Bangalore City shows an evidence of warming trend at a statistical confidence level of 99.9 %, and that warming effect is visible in terms of increase of minimum temperature at a rate higher than that of maximum temperature. Interdependence studies between temperature and extreme rainfall reveal that up to a certain range, increase in temperature intensifies short term rainfall intensities at a rate more than the average rainfall. From these two findings, it is clear that short duration rainfall intensities may intensify in the future due to global warming and urban heat island effect. The possible urbanization signatures in the extreme rainfall in terms of intensification in the evening and weekends are also inferred, although inconclusively. The IDF relationships are developed with historical data and changes in the long term daily rainfall extreme characteristics are studied. Multidecedal oscillations in the daily rainfall extreme series are also examined. Further, non-parametric trend analyses of various indices of extreme rainfall are carried out to confirm that there is a trend of increase in extreme rainfall amount and frequency, and therefore it is essential to the study the effects of climate change on the IDF relationships of the Bangalore City. Estimation of future changes in rainfall at hydrological scale generally relies on simulations of future climate provided by Global Climate Models (GCMs). Due to spatial and temporal resolution mismatch, GCM results need to be downscaled to get the information at station scale and at time resolutions necessary in the context of urban flooding. The downscaling of extreme rainfall characteristics in an urban station scale pose the following challenges: (1) downscaling methodology should be efficient enough to simulate rainfall at the tail of rainfall distribution (e.g., annual maximum rainfall), (2) downscaling at hourly or up to a few minutes temporal resolution is required, and (3) various uncertainties such as GCM uncertainties, future scenario uncertainties and uncertainties due to various statistical methodologies need to be addressed. For overcoming the first challenge, a stochastic rainfall generator is developed for spatial downscaling of GCM precipitation flux information to station scale to get the daily annual maximum rainfall series (AMRS). Although Regional Climate Models (RCMs) are meant to simulate precipitation at regional scales, they fail to simulate extreme events accurately. Transfer function based methods and weather typing techniques are also generally inefficient in simulating the extreme events. Due to its stochastic nature, rainfall generator is better suited for extreme event generation. An algorithm for stochastic simulation of rainfall, which simulates both the mean and extreme rainfall satisfactorily, is developed in the thesis and used for future projection of rainfall by perturbing the parameters of the rainfall generator for the future time periods. In this study, instead of using the customary two states (rain/dry) Markov chain, a three state hybrid Markov chain is developed. The three states used in the Markov chain are: dry day, moderate rain day and heavy rain day. The model first decides whether a day is dry or rainy, like the traditional weather generator (WGEN) using two transition probabilities, probabilities of a rain day following a dry day (P01), and a rain day following a rain day (P11). Then, the state of a rain day is further classified as a moderate rain day or a heavy rain day. For this purpose, rainfall above 90th percentile value of the non-zero precipitation distribution is termed as a heavy rain day. The state of a day is assigned based on transition probabilities (probabilities of a rain day following a dry day (P01), and a rain day following a rain day (P11)) and a uniform random number. The rainfall amount is generated by Monte Carlo method for the moderate and heavy rain days separately. Two different gamma distributions are fitted for the moderate and heavy rain days. Segregating the rain days into two different classes improves the process of generation of extreme rainfall. For overcoming the second challenge, i.e. requirement of temporal scales, the daily scale IDF ordinates are disaggregated into hourly and sub-hourly durations. Disaggregating continuous rainfall time series at sub-hourly scale requires continuous rainfall data at a fine scale (15 minute), which is not available for most of the Indian rain gauge stations. Hence, scale invariance properties of extreme rainfall time series over various rainfall durations are investigated through scaling behavior of the non-central moments (NCMs) of generalized extreme value (GEV) distribution. The scale invariance properties of extreme rainfall time series are then used to disaggregate the distributional properties of daily rainfall to hourly and sub-hourly scale. Assuming the scaling relationships as stationary, future sub-hourly and hourly IDF relationships are developed. Uncertainties associated with the climate change impacts arise due to existence of several GCMs developed by different institutes across the globe, climate simulations available for different representative concentration pathway (RCP) scenarios, and the diverse statistical techniques available for downscaling. Downscaled output from a single GCM with a single emission scenario represents only a single trajectory of all possible future climate realizations and cannot be representative of the full extent of climate change. Therefore, a comprehensive assessment of future projections should use the collective information from an ensemble of GCM simulations. In this study, 26 different GCMs and 4 RCP scenarios are taken into account to come up with a range of IDF curves at different future time periods. Reliability ensemble averaging (REA) method is used for obtaining weighted average from the ensemble of projections. Scenario uncertainty is not addressed in this study. Two different downscaling techniques (viz., delta change and stochastic rainfall generator) are used to assess the uncertainty due to downscaling techniques. From the results, it can be concluded that the delta change method under-estimated the extreme rainfall compared to the rainfall generator approach. This study also confirms that the delta change method is not suitable for impact studies related to changes in extreme events, similar to some earlier studies. Thus, mean IDF relationships for three different future extreme events, similar to some earlier studies. Thus, mean IDF relationships for three different future periods and four RCP scenarios are simulated using rainfall generator, scaling GEV method, and REA method. The results suggest that the shorter duration rainfall will invigorate more due to climate change. The change is likely to be in the range of 20% to 80%, in the rainfall intensities across all durations. Finally, future projected rainfall intensities are used to investigate the possible impact of climate change in the existing drainage system of the Challaghatta valley in the Bangalore City by running the Storm Water Management Model (SWMM) for historical period, and the best and the worst case scenario for three future time period of 2021–2050, 2051–2080 and 2071–2100. The results indicate that the existing drainage is inadequate for current condition as well as for future scenarios. The number of nodes flooded will increase as the time period increases, and a huge change in runoff volume is projected. The modifications of the drainage system are suggested by providing storage pond for storing the excess high speed runoff in order to restrict the width of the drain The main research contribution of this thesis thus comes from an analysis of trends of extreme rainfall in an urban area followed by projecting changes in the IDF relationships under climate change scenarios and quantifying uncertainties in the projections.
