The 1990&#039 / s witnessed the emergence of Constructivist approach in the International Relations theory. Constructivism rejecting the rationalist precepts of Neo-Realism and Neo-Liberalism brought a sociological point of view to the world politics mentioned the role of ideational factors in the constitution process of interests and identities. Constructivism assumes that there is a mutual constitution process between states and normative structures in which states internalized existing international societal norms with efforts of international non-state actors seen as active teachers guiding states to initiate policies that are congruent with international civilized norms of behaviour. Today human rights are defined as civilized normative patterns. At this point five phase spiral model reveals itself and introduces explanations for how states understand, interpret and internalize international human rights norms. The model assumes that target state&#039 / s identity, interest and behaviors are influenced by international human rights norms as it progresses through the model&#039 / s five phased spiral process. The model in this process emphasizes roles and efforts of international organizations. v This work assesses the usefulness of the five phase spiral model and Constructivism as an explanation of the changes in the Turkish government&rsquo / s human rights practices. As case study effect of the European Union over normative transformation in the field of human rights in Turkey will be given. The thesis bringing criticisms to the model&rsquo / s assumptions in Turkey case will assert that Turkey, from the 1980 Military intervention to the end of 2007 has made progressive steps in line with the phases mentioned in the spiral model.

本研究主要探討的是國際標準化商品的製造業者如何從事產品創新，特別是針對一個企業銷售的產品就是標準化的完成品，最典型的例子，就是台灣佔有亞太最大產能的影音DVD光碟片製造業。差異化是企業提升競爭力的主要手段，也是經常被企業採用的競爭策略。一個企業可以尋求差異化的空間顯然和自己產品或服務被標準化的程度有關。產品「被標準化」的程度越高，除了創意越容易受限，組織出現「核心僵固」的情形可能也越嚴重。 本研究延續組織知識創造學說「知識螺旋」理論的精髓，提出「創新螺旋」策略規劃程序的理論模型架構，「創新螺旋」模型是一個以產品創新為主軸的策略規劃程序，以行銷導向創新策略為其核心。行銷導向的創新是一個企業核心能耐經組織內部「共同化」，「外化」訴諸市場，再與市場需求「結合」串連，「內化」為企業策略的過程，意謂著企業核心價值與市場價值缺口產生共鳴的「知識螺旋」。「創新螺旋」模型描述企業應以「市場價值、創造價值、核心價值」做為產品創新的核心概念，以「創新是兩種看似不相干的事物將其成功結合」的中心思想，同時秉持「創新來自邊陲的精神」，尋求產品創新上的突破。 一般而言，國際標準規格的制訂是由大國大廠所主導，技術開發首動者的效益來自參與規格制訂及日後商品上市後收取的龐大權利金。一般小廠小國，市場影響力小、技術開發資源有限，不易參與規格角力的競賽，更遑論發揮舉足輕重的影響力，這是一個殘酷的國際現實。因此小廠小國的標準化商品的製造業者，如何從事產品創新就是本研究所要探討的課題。本研究探討的個案公司以「創新螺旋」策略規劃程序的理論模型做為其產品創新的藍本，檢視在此情境下的台灣影音DVD碟片的製造業者，在產品創新過程遭遇到的困境及其突圍的方式。本研究同時觀摩比較其他國際級的競爭同業，如何發揮其地理環境上的優勢及本身的核心能耐，在次世代藍光DVD來臨之繼，創造更有利的競爭條件。 / This thesis aims to study how to do the product innovation under the condition as the core product or service of one corporate is an international standardized end product. The typical example is such as the video DVD disc manufacturers in Taiwan, who own the major market share in the world wide total throughput. From the strategic point of view, “differentiation” has been widely used to build up a corporate core competency. However, the limitation for one corporate to do the product differentiation is corresponding to its product status being standardized. The higher standardized condition on product it is, the more limitation on creation it will be. It also will cause the organization to be inflexible, furthermore becomes stubborn. Generally speaking, international standard has been formulated by the strong or big countries and international corporate. The first mover advantage to develop the product should be as a format creator and as a licenser in the long run as into the commercialized phase. On the other hand, usually, for the small companies or countries, it has less technology resource and marketing power to influence the standard formation. Under such kind of situation, is there any chance for the small companies to do the product innovation? This is the main topic for the thesis to investigate. This research extends the organization knowledge creativity theory by Nonaka (1995) as the “Spiral of Knowledge” to a new model as “Spiral of Innovation”, which presents the sequence of strategy formation in term of product innovation. Marketing-oriented product developing pattern is the main pursuit of the “Spiral of Innovation”. The first step, through the ”socialization” inside the corporate, the common understanding of the corporate standing position can be created. As for product developing, targeting to find out the customers need or the lack in the marketing, those finding should be put into the step as “externalization”. After that, through “combination” of marketing need and corporate competency, the systematic concept can be developed. The final step, all the above can be converted into the organization function inside corporate, which is called as “internalization”. “Spiral of Innovation” theory states, for a corporate, it takes the “marketing value, creating value and corporate core value” as the core product developing concept. The innovation can be simply interpreted as “the success to combine two dissimilar or irrelevant matters”. Innovation usually generates from that being lack of concern or attention. This research studies the case, Taiwan No.1 video DVD disc manufacturer, which implements the “Spiral of Innovation” model as the framework of its product developing strategy formation. It shows the dilemma the corporate faces in the effort for product differentiation and those attempts it took for breakthrough. It also compares the product developing strategy with some other key and leading players from USA, Europe and Japan. From innovation point of view, those companies intend to exploit their advantage from location and core competency to find out the optimal position for the coming next generation high density DVD era.

Aerospace Engineering / The aim of this thesis is to explore the high strain rate behavior of metallic specimens using electromagnetic inductive loading as the means to inflict the required high strain rate deformation on laboratory scale specimens, allowing for controlled, repeatable experiments to be performed. Three separate experiments were designed and performed, using helical and spiral coils as the sources of radial and unidirectional loading. The first experiment evaluated the effect of applying a polymer coating on 30.5 mm diameter, Al 6061- O tube samples, in two lengths, 18 and 36 mm. The expanding tube experiment was used to apply a radial loading on the specimens and record the event. Several optical techniques were then used to evaluate the behavior of the samples. Coatings of polyurea and polycarbonate were used. It was observed that the polycarbonate coating seemed to have a more profound effect on the behavior of the metal, by applying a larger restraining pressure on the tube surface during the expansion process, and thereby modifying the stress state of the specimen. The second experiment looked to design an experimental arrangement to test the plane strain, high strain rate behavior of Al 6061-O tubes of different lengths. A 112 mm long solenoid was designed and manufactured, and testing was performed on 30.5 mm diameter Al 6061-O tubes in lengths of 50, 70 and 90 mm. It was observed that the coil behaved similar to shorter ones at low voltages and that the longer the specimen used, the more its deformation path approached a plane strain condition. Finally, a third experiment was performed to develop an experiment to accelerate a plate to high linear velocities, as a means to evaluate the use of a flat spiral coil as the driver for future experiments based upon electromagnetic inductive loading. A prototype coil was manufactured and installed into a converted expanding tube experimental setup. Three samples were tested in several sizes, and materials: aluminum and steel. Speeds in the range of 45 to 251 m/s were obtained, validating the apparatus as a viable method to provide a unidirectional loading. / text

Since the 30's and Edwin Hubble's famous classification, galaxies are usually separated in twogroups : the late-type galaxies (LTGs) and the early-type galaxies (ETGs). The LTGs family ismainly made of spiral galaxies (S) while the ETGs family is composed of elliptical (E) and lenticular(S0) galaxies. A morphological study of all these galaxies revealed that around 60% of LTGs and45% of S0 present a bar. It has also been shown that, in the local Universe, galaxies fall into twobig groups : the blue cloud mostly populated by LTGs and the red sequence mainly made of ETGs.Several mechanisms are responsible for this distribution and the secular evolution is obviously animportant one to examine, sepcially in the context of bars, as an important number of studiesshowed the importance of bars in the dynamics and evolution of a galaxy.The goal of my thesis is to study the importance of the formation and ensued bar-drivenevolution influence on ETGs evolution. In that context, I have performed N-body simulations ofbarred (and unbarred) galaxies in order to investigate the following issues.First of all, I focused on the influence of a bar in a galaxy when modelling it with a dynamicalmodel assuming an axisymmetric mass distribution. As these kinds of models allow to determine themass-to-light ratio M/L, thus the dynamical mass of an observed galaxy, but also its inclinationand its anisotropy, it is important to evalute the consequence of the presence of a bar on theseparameters. I have shown that, depending on the galaxy inclination and the bar position angle,M/L is most of the time biased and overestimated, and this can be up to 25%. The size andstrength of the bar also seem to be important factors but a deeper study has to be done to quantifythis preliminary result.In a second step, I have studied the role of bars on the mass and metallicity redistributionsin a lenticular galaxy. I confirmed that the presence of a bar, due to its influence on its hostsystem dynamics, flattens pre-existing metallicity gradients. Moreover, I showed that the degree offlattening and the position of affected regions are directly correlated with the bar structure and thelocation of the dynamical resonances. Nonetheless, this dynamical effect cannot explain the varietyof observed ages and metallicity gradients. The consequences of a barred gravitational potentialon the gas dynamics and the stellar formation should therefore be investigated. This is the topicof the last set of numerical simulations produced which will allow to better understand the globalinfluence a bar has on the secular evolution of ETGs.

The construction of the Canadian Pacific Railway (CPR) was not a conquest of man over nature as some historians have suggested and the driving of the last spike did not cement that victory. By studying the CPR from an environmental perspective, it becomes obvious that the relationship between the people and the environment in the mountains was two-fold: workers had an effect on the environment through fires, deforestation, excavation, and blasting, and the environment likewise had an effect on workers through the hardships of weather, challenging terrain, avalanches, and floods. Shortcuts, such as steep grades and wooden bridges, taken by the CPR throughout construction to save money and time, as well as the poor route choice, had unintended consequences for the operation of the railway. Massive deforestation and fires had repercussions for the watershed of the eastern Rocky Mountains and the choice of Rogers Pass meant that the CPR had to deal with numerous avalanches and deep snow. Steep grades and lines that were easily flooded or open to avalanches resulted in the deaths of numerous workers and expensive repairs to engines and the track. The construction of the CPR also had a notable impact on western Canada as it opened up the land to tourism, settlement, agriculture, and the lumber and mining industries. In building and operating the line, the CPR had to learn to adapt to the environment in order to carry out repairs quickly and get trains through.

By using Lyapunov exponents, bifurcation diagrams, and trajectories in the phase-space, to numerically characterize the dynamics of the model in a parameter plane, we show that it presents typical periodic structures embedded in a chaotic region, forming spiral structures that coils up around a focal point while period-adding bifurcation take place. / Nesse trabalho investigamos planos de parâmetros construídos para um conjunto de três equações diferenciais ordinárias, autônomas, não lineares de primeira ordem com dez parâmetros que modela uma cadeia alimentar tritrófica. Usamos expoentes de Lyapunov, diagramas de bifurcação, e curvas no espaço de fase para caracterizar numericamente a dinâmica do modelo em um plano de parâmetro e, mostramos que este apresenta estruturas periódicas típicas em meio à regiões caóticas, formando espirais que se enrolam ao redor de um ponto focal ao passo que surgem bifurcações de adição de período.

Esta dissertação apresenta modelagem matemática e um método de solução numérica para problemas de conformação eletromagnética de chapas metálicas finas circulares utilizando uma bobina em espiral plana. O método foca especificamente o cálculo do campo eletromagnético gerado pela bobina e análise do circuito que modela o sistema de estampagem eletromagnética. A bobina plana é aproximada por círculos concêntricos carregando a corrente de descarga dos capacitores. Os cálculos das correntes induzidas e perfil da força eletromagnética na chapa e acoplamentos magnéticos entre a bobina e chapa metálica são realizados para o instante inicial, antes da deformação plástica da chapa. O método utiliza a lei de Biot-Savart, sendo que a solução das integrais obtidas para indução magnética é realizada através de métodos numéricos, considerando as simetrias do problema. Para verificação da modelagem matemática, da solução numérica e comprovação da viabilidade técnica deste processo, um dispositivo de estampagem eletromagnética foi desenvolvido e diversos experimentos foram realizados com chapas de alumínio. Os parâmetros investigados foram a espessura da chapa a ser deformada e a influência da presença de vácuo na cavidade da ferramenta. Os resultados experimentais demonstram concordância com os resultados da modelagem proposta. A presença de vácuo também demonstrou um incremento na deformação da chapa. A rotina desenvolvida no software Matlab fornece informações importantes para o processo e permite que se faça ajustes no dispositivo. / This dissertation presents a mathematical model and numerical method to solve the problems of electromagnetic forming of thin circular metal sheets by using a flat spiral coil. The method focuses specifically on the calculation of the electromagnetic field generated by the coil flat and circuit analysis modeling system electromagnetic forming. The flat coil is approximated by concentric circles carrying a discharge current of capacitors. The calculations of induced currents and profile of the electromagnetic force on the plate and magnetic coupling between the coil and sheet metal are made to the initial time, before the plastic deformation of the plate. The method uses the law of Biot-Savart, and the solution of the integral obtained for magnetic induction is performed by numerical methods, considering the symmetries of the problem. To verify the mathematical model, the numerical solution and proving the technical feasibility of this process, a electromagnetic forming device was developed and several experiments were made with aluminum plates. The parameters investigated were the thickness of the plate to be deformed and the influence of the vacuum in the cavity of the tool. The experimental results show agreement with the results of the proposed model. The presence of vacuum also showed an increase in the deformation of the plate. A routine developed in software Matlab provide important information for the process and allow to make adjustments on the device.

Summaries in Afrikaans and English / Outcomes-Based Education forms the foundation of South Africa's revised national education curriculum, known as The Revised National Curriculum Statement Grades R-9. The Van Hiele Model, developed for the teaching and learning of geometry, has already been used successfully in the school curricula of the Netherlands and Russia. Strong support for this theory exists in leading countries like America and Europe. This study has investigated the possible relationship between the Van Hiele theory and the "Revised National Curriculum Statement Grades R-9" and through critical evaluation found a great compatibility between them. Both are giving strong support for the spiral approach to mathematics education. It is recommended that all geometry learning programmes and teaching units be moulded on the Van Hiele Model. / Suid-Afrika se hersiene nasionale onderwyskurrikulum, die "Revised National Curriculum Statement Grades R-9" word deur uitkomsgebaseerde onderwys gefundeer. Die Van Hiele Model vir die onderrig en leer van meetkunde, is suksesvol in skoolkurrikula van Nederland en Rusland toegepas en geniet wye steun in lande soos Amerika en Europa. Hierdie navorsing het die moontlike verband tussen die Van Hiele raamwerk en die nuwe kurrikulum ondersoek en deur kritiese evaluering baie sterk versoenbaarheid tussen die "Revised National Curriculum Statement Grades R-9" en die Van Hiele Model gevind.
