In this thesis I explore the emergence of the Christian triad with reference to two contemporary movements: Middle Platonism and Gnosticism. The earliest Christian writer to enumerate the three constituents of what would become the Christian Trinity is Justin. In addition to his three extant works, Justin’s triadology can be diagnosed from those he directly influenced – Tatian and Athenagoras – who I have (somewhat artificially) grouped under the heading the “school of Justin”. The ontological triad adopted by these Christian thinkers is compared with the triads of Middle Platonism and Gnosticism, both in terms of their structure and in terms of the function and ontological status of the individual constituents of these triads. In this thesis I propose that a liturgical triad of primitive Christianity, the trine baptismal formula, was conflated by the “school of Justin” with the ontological triad of Middle Platonism, resulting in three referents of the baptismal formula being embued with new functions and ontological status. Whilst emerging as a hierarchical triad, the logic of Platonic ontology when combined with Christian tradition required the sharp distinction between God, as Being, and all other things resulting in a Christian triad that was also a unity. This new triad became fixed as a central tenet of Christianity. I find no plausible connection between any known Gnostic triad and the triad of the “school of Justin”. There is some interaction between Gnostic and Platonic thought during this period. It is possible that the Triple-Powered One pre-empted the Being-Mind-Life triad of Neoplatonism.

M.A. / Any organization or structure over time has a historical background, a reason for existence, and an objective. In this sense PAGAD is no exception. The aim of the following discussion is to place the establishment of PAGAD within a broader historical and ideological context. This section will be discussed under the following headings: Broad historical context. The objective of this heading is to state clearly that the establishment of PAGAD was not an one time only decision taken by a few disillusioned members of the community in the Western Cape. Indications are that the establishment of anti-crime forums had been present since the 1950s, each with different members, but always with the same purpose and goals. The main objective of this section is to indicate to the reader that the establishment of PAGAD had had a historical development. Fight against crime as explanatory condition. On the basis of the above-mentioned historical development, this section will be focussing on the socio-economical conditions prevailing in the Western Cape, in order to explain the development of so-called popular justice organizations. Ideological context of the rise of People Against Gangsterism and Drugs. The name of the organization already puts it against the background of tenn "popular justice". This section will attempt to put PAGAD in the framework of Muslim politics in the Western Cape. Division in PAGAD. This section will be focussing on the split in PAGAD during September 1996, on the ground of the ideological divisions in the Muslim community in the Western Cape. Although the split in the ranks of PAGAD occurred very early in the existence of the organization, it is very important to take notice of it, as the split was a result of the manifestation of ideological differences. There will be continuous reference to the said split in the cause of this case study as it altered PAGAD's objectives as well as its modus operandi. Relationship between PAGAD and Qibla and the strategy and objectives of Qibla. The objective of this section is to look into Qibla as such and to study Qibla's alleged role in the actions of PAGAD. Discussion on the aforementioned should not be seen as isolated from each other, but that it should be interpreted as a totality.

This thesis documents a collection of experimental investigations in which a differentially-heated annulus was used to investigate the effects of topography on the atmospheric and oceanic circulation. To this end a number of experiments were devised, each using a different topographic base to study a different aspect of the impact of topography, motivated by the most notable outstanding questions found in a review of the literature, namely exploring the effects of topographic resonance, blocking via partial barriers, and azimuthally differential-heating via thermal topography. First of all, whilst employing sinusoidal wavenumber-3 topography to extend the experimental parameter space of a similar study, namely Read and Risch (2011), a new regime within a region of structural vacillation was encountered. Denoted as the ‘stationary-transition’ regime, it featured periodic oscillations between a dominant stationary wavenumber-3 flow and axisymmetric or chaotic flow. An investigation into topographic resonance followed, keeping the wavenumber-3 base, but with a sloped lid to add a beta effect to the annulus. This acted to increase the occurrence of stationary waves, along with the ‘stationary-transition’ regime, which was discovered to be a near-resonant region where nonlinear topographic resonant instability led to a 23 to 42 ‘day’ oscillatory structure. The base was then replaced with an isolated ridge, forming a partial barrier to study the difference between blocked and unblocked flow. The topography was found to impact the circulation at a level much higher than its own peak, causing a unique flow structure when the drifting flow and the topography interacted in the form of an ‘interference’ regime at low Taylor Numbers, as well as forming an erratic ‘irregular’ regime at higher Taylor Numbers. Lastly, this isolated ridge was replaced by flat heating elements covering the same azimuthal extent, in order to observe whether thermal topography could be comparable to mechanical topography. These azimuthally-varying heating experiments produced much the same results as the partial barriers study, despite the lack of a physical peak or bottom-trapped waves, suggesting that blocking is independent of these activities. Evidence of resonant wave-triads was noted in all experiments, though the component wavenumbers of the wave-triads and their impact on the flow was found to depend on the topography in question.

A teoria da perturbação baseada em múltiplas escalas temporais é usada neste trabalho para estudar as interações não lineares entre ondas na atmosfera no contexto das equações primitivas no plano beta-equatorial em coordenadas isobáricas. As ondas equatoriais de Rossby, mista Rossby-gravidade, gravidade-inerciais e Kelvin, com diferentes estruturas verticais, são obtidas como soluções de ordem dominante. A partir da condição de solvabilidade do problema de ordem superior, foi obtido um modelo assintótico reduzido que governa a interação fracamente não linear entre as ondas numa determinada tríade ressonante. A conservação da energia total para a solução de ordem dominante do modelo de equações original implica que a soma dos coeficientes de interação numa tríade ressonante qualquer deve ser nula. Usando um método gráfico, foram encontradas algumas tríades ressonantes envolvendo ondas baroclínicas equatorialmente confinadas e ondas de Rossby barotrópicas possuindo significativa influência em médias e altas latitudes. Duas tríades ressonantes receberam especial atenção devido ao significativo acoplamento entre os modos e à possível relação desses modos com alguns aspectos observados acerca dos fenômenos de baixa freqüência na atmosfera. A primeira tríade é composta por uma onda de Rossby barotrópica possuindo o segundo modo meridional interagindo ressonantemente com uma onda mista de Rossby-gravidade com a estrutura vertical do primeiro modo baroclínico, ambas possuindo o mesmo número de onda zonal, por meio de um modo geostrófico zonalmente simétrico (k = 0) possuindo a mesma estrutura vertical da onda mista e o modo meridional n = 1. A segunda tríade é constituída por uma onda mista de Rossby-gravidade com número de onda-2, uma onda de Kelvin com número de onda-1, ambas associadas ao primeiro modo baroclínico, e uma onda de Rossby barotrópica com número de onda-3 e modo meridional n = 2. A integração das equações reduzidas para essas duas tríades ressonantes mostra que para as amplitudes iniciais dos modos caracterizando magnitudes típicas de anomalias atmosféricas observadas, os modos na primeira tríade, em geral, trocam energia na escala intra-sazonal, enquanto os modos na segunda tríade trocam energia na escala intra-sazonal ou numa escala semi-anual, dependendo da amplitude inicial do modo de Rossby barotrópico. São discutidas as implicações dos resultados para a dinâmica da interação trópicos-extratrópicos na escala de baixa-freqüência do espectro dos movimentos atmosféricos. / The asymptotic perturbation theory based on multiple scales in time is used to investigate the nonlinear interactions among equatorial waves in an equatorial beta-plane adiabatic primitive equation atmospheric model in isobaric coordinates. The equatorial Rossby, mixed Rossby-gravity, Kelvin and inertio-gravity waves, with several vertical structures, are obtained as the leading-order solution. From the solvability condition of the problem, a reduced model governing the weakly nonlinear interaction of the waves in a particular resonant triad was obtained. The total energy conservation of the leading-order solution of the original model equations implies that the sum of the coupling coefficients in any resonant triad must be zero. Using a graphical approach, we determined some resonant triads involving equatorially trapped baroclinic waves and barotropic Rossby waves having large mid-latitude amplitude. Two particular interactions deserve special attention because of their strong coupling and their possible relation to observed features in the atmospheric circulation. One is characterized by a first baroclinic mode structure mixed Rossby-gravity wave interacting with a barotropic Rossby wave with the second gravest meridional mode, both having the same wavenumber, through a zonally symmetric geostrophic mode with the same vertical structure as the Yanai wave and having the n = 1 meridional mode. The other triad is composed of a zonal wavenumber-1 Kelvin wave, a zonal wavenumber-2 mixed Rossby-gravity wave, both with the first baroclinic mode vertical structure, and a barotropic zonal wavenumber-3 Rossby wave having the second gravest meridional mode. The barotropic Rossby waves in these two triad interactions have significant projection onto middle and higher latitudes. The integration of the triad equations for these particular interactions shows that, for the initial mode amplitudes characterizing typical magnitudes of atmospheric flow perturbations, the modes in the first triad usually exchange energy on intraseasonal time-scales, while the modes in the second triad exchange energy on either intraseasonal or semi-annual time-scale, depending on the initial condition. The implications of the results for the dynamics of tropics-extratropics interaction on low-frequency time-scales are discussed.

O crescimento do uso dessa fonte desenvolveu uma indústria na Europa e nos Estados Unidos para atender à demanda desses mercados precursores. Na última década, o Brasil, juntamente com a China e a Índia, vem investindo na geração eólica, e destacando-se no cenário mundial. A implantação de parques eólicos acontece por meio de projetos interorganizacionais (PIOs), envolvendo atividades compartilhadas entre empresas com interesses e capacidades diferentes em um ambiente de riscos e incertezas. Esta pesquisa propõe-se a contribuir com a temática ainda nova dos PIOs da indústria eólica, tendo sustentação nos progressos recentes do conhecimento sobre redes e propriedades estruturais. O objetivo principal é compreender as implicações das propriedades estruturais das redes estabelecidas no contexto dos PIOs de geração de energia eólica para seu gerenciamento. Estudos recentes têm adotado a perspectiva de redes para a compreensão e o aprimoramento das relações nos PIOs. Nesses estudos, os PIOs são entendidos como uma rede de atores interdependentes que pode ser detalhada a partir de suas propriedades estruturais em vários níveis. O mapeamento da rede, sua análise e caracterização a partir de múltiplos níveis iluminam questões até então complexas para o desenvolvimento dos parques eólicos. A introdução do nível triádico permitiu novas visões aos aspectos estruturais e posicionais dos atores. As redes são um fenômeno relativamente recente, e o campo de estudos ainda se ressente com a falta de pesquisas que abordem as estruturas relacionais entre os atores. A utilização conjunta de abordagens quantitativas, com a adoção da Análise de Redes Sociais, e qualitativas, com a realização de entrevistas semiestruturadas, possibilitou incorporar diferentes (e complementares) perspectivas de análises ao fenômeno. Em termos acadêmicos, uma das contribuições da pesquisa foi o desenvolvimento de um conceitual teórico para as propriedades estruturais dos PIOs em vários níveis, reforçando o poder explicativo da estrutura frente ao dos atributos individuais dos atores. Outra contribuição foi a identificação de relações e papéis-chave para a estruturação de modelos de gestão mais efetivos. Relações informais, invisíveis nas redes de fornecimento e contratos, acontecem dentro de uma lógica cooperativa, e são importantes na coordenação do projeto. Em termos gerenciais, as contribuições centraram-se na compreensão da estrutura relacional dos PIOs, de seu funcionamento, e em aspectos relacionados às implicações das propriedades estruturais para seu gerenciamento. A composição e organização dos PIOs foi revelada assim como a importância da cooperação ou de uma estrutura relacional que estimule a cooperação entre os participantes do projeto. / One of the priorities of sustainable world agenda is promoting the use of renewable energy sources, like wind power. The growth of this source developed an industry in Europe and in the United States to supply the demand of these precursors markets. Recently (in the last decade), Brazil along with China and India has been investing in wind generation and emerging on the world scenario. The deployment of wind farms happens through inter-organizational projects (IOPs), involving shared activities among companies with different interests and capabilities in an environment of risks and uncertainties. This research aims to contribute to the still new topic of the wind industry IOPs, having support in recent progress of knowledge on networks and structural properties. Its main goal is to understand how the characteristics of networks established in the context of wind power generation IOPs affect the development of Brazilian initiatives. Recent studies have adopted social networking perspective for understanding and improving relations in IOPs. In these studies, IOPs are understood as a network of interdependent actors that can be detailed from their structural properties at various levels. Network mapping, analysis and characterization from multiple levels shed light to issues hitherto complex for the development of wind farms. The introduction of the triadic level, still little explored in studies of interorganizational networks, enables new visions to actors structural and positional aspects. The networks are a relatively new phenomenon, and the field of study still resents the lack of research that address the relational structures between the actors. The joint use of quantitative approaches, with the adoption of social network analysis, and qualitative, based on semi-structured interviews, made it possible to incorporate different (and complementary) analysis perspectives to the phenomenon. In academic terms, one of the research contributions was the development of a theoretical framework for the structural properties of IOPs on many levels, reinforcing the explanatory power of the structure over the individual attributes of the actors. Another result was the identification of relations and key roles for structuring more effective management models. Informal relations, invisible in supply and procurement networks, happen within a cooperative logic and are important in coordinating the project. In managerial terms, the contributions focused on understanding the relational structure of the IOPs, their operation, and issues related to the implications of the structural properties to its management. The composition and organization of IOPs was revealed as well as the importance of cooperation or of a relational structure that encourages cooperation between project participants.

The differentiation between functional areas is necessary for organizations to be able to meet the challenges posed by the environment. This same differentiation, however, requires the functional integration for organization can operate to achieve their goals and use their resources efficient. This paper uses the perspective of triads, an approach of Social Psychology that studies groups of subjects for the analysis of phenomena associated with the relationships between functional areas of an organization. This approach has been used recently in the study of the relationship between organizations in supply chains. Multiple case studies was conducted in three industrial companies in the region of Uberlandia (MG) and six categories of phenomena that help to understand the relationship between functional areas were identified: Urgency, Capacity vs. Demand, Motivation, Challenge and Respect. Existing theories that adopt the perspective of triads, the Theory of Balance of Heider, Theory of Structural Holes, by Simmel and Theory of Coalitions by Caplow were also used for data analysis. Seven propositions were made regarding the phenomena associated with functional integration from the perspective of triads that can contribute to future studies in this research field. / A diferenciação entre as áreas funcionais é necessária para que as organizações sejam capazes de enfrentar os desafios impostos pelo ambiente. Essa mesma diferenciação, no entanto, exige a integração interfuncional para que a organização consiga operar de forma a atingir seus objetivos, utilizando seus recursos de forma eficiente. Este trabalho utiliza a perspectiva de tríades, uma abordagem da Psicologia Social que estuda grupos de indivíduos, para a análise dos fenômenos associados aos relacionamentos entre as áreas funcionais de uma organização. Essa abordagem tem sido recentemente utilizada no estudo do relacionamento entre organizações nas cadeias de suprimentos. Foi realizado um estudo de múltiplos casos em três empresas industriais da região de Uberlândia (MG) e a partir dos dados foram identificadas seis categorias de fenômenos que ajudam a compreender o relacionamento entre as áreas funcionais: Urgência, Capacidade versus Demanda, Motivação, Desafio e Respeito. As teorias existentes que adotam a perspectiva de tríades, a Teoria do Equilíbrio de Heider, a Teoria dos Buracos Estruturais, de Simmel e a Teoria das Coalizões, de Caplow também foram utilizadas para a análise dos dados. Foram feitas sete proposições a respeito dos fenômenos associados à integração interfuncional a partir da perspectiva de tríades que podem contribuir com estudos futuros neste campo de pesquisa. / Mestre em Administração
