In this sense the problem of search was: What are the links between attitudes towards geometry, confidence in problem-solving geometric and knowledge reporting and procedural relating to the geometry flat? Due to this problem have been worked four issues of research on the inquiry. They are: 1) Is there a relationship between the attitude on the geometry and the thorough of geometric knowledge?; 2) Is there a relationship between confidence in problem-solving geometric and knowledge in geometry?; 3) Is there a relationship between confidence in problem-solving geometric and attitude on the geometry?, and 4) What ate the main difficulties faced by prospective teachers of Mathematics to solve problems involving geometric concepts such as congruency and similarity of triangles, the rectangle and triangle and metric relations in the triangle rectangle; area and equivalence of triangles? Participants in search were 71 students of a course in Bachelor of Mathematic from a Public University of São Paulo State. For data collection were used various instruments, among them: scale of attitudes towards geometry, 3 proof of knowledge of flat geometry with descant issues, 3 trust tests related to evidence of knowledge of plane geometry and a questionnaire for information. The analyses data showed correlation of attitude with regard to the geometry with the overall performance in tests of geometric knowledge and confidence with the overall solution of geometric problems. There were significant differences in the gender factor, and that both, the attitudes as the confidence and performance were more positive for the male participants in relation to female participants. On the performance... (Complete abstract click electronic access below) / Mestre

Para alcançar meu propósito, trilho um percurso que revê leituras que a crítica operou dos referidos livros sempre as inquirindo , problematiza os conceitos de ficção, realidade e História em suas implicações com a linguagem e, por fim, estuda as marcas do gênero romance e, particularmente, o papel da personagem de ficção (como individualidade ou como grupo) nessa esfera. Ainda que os dois textos literários sejam postos frente a frente em mais de um momento, não é aos referenciais da Literatura Comparada que eu me volto com maior constância; antes, às propostas de ISER (2002; 1997) para o estudo da ficcionalidade e de LUKÁCS (2000) e de BAKHTIN (1978) para o romance. Desprezando a eleição de fundamentos homogêneos para a discussão levada a cabo, recorro a vários teóricos e comentadores para embasar a minha própria visão das questões que abordo. Também fugindo à convencionalidade, analiso os romances pari passu às reflexões teóricas, o que, calculo, oferece maior organicidade à tese. Ao termo de minha investigação, foi possível perceber que (a) sendo o romance um gênero caracteristicamente multifacetado, é um instrumental de diversa cepa que fornece bases mais pertinentes ao seu inquérito, sempre com ênfase na inscrição histórica dos discursos; (b) os comentários que os autores literários emitem sobre as respectivas composições podem ser tomados como ponto de partida para a análise dos textos, mas, jamais, como referência inelutável; (c) tanto em Tortilla Flat como em Esteiros e por motivações distintas , a presença de um suposto protagonista coletivo não é capaz de lenificar o papel desempenhado pelos indivíduos ficcionais

The study addresses the problem, already identified in 1986 by Msimang that definitions such as Bascom's (1965) fail to differentiate clearly between historical narratives and legends. To evolve a more accurate definition, this study considers two Sepedi dramas: Make's Sello sa Tonki le Pere and Moloma's Marangrang (1972). The qualitative approaches (explain, interpret and compare) used in this study show that legends and historical dramas/narratives can be investigated by comparing them to identify differences between these genres. A narratological model suggested by Marggraff (1994) is used, considering three strata (layers) of a text: content, plot and style of writing. The topic, theme and atmosphere are explored, in that order, in the selected texts. The analysis suggests that the differences between a legend and a historical drama/novel arise from two elements: characters and their actions. In a legend, there are three important pillars: the exposition, the body and the conclusion. The exposition of a legend has five formulaic features: Kgalekgale [long, long ago ], Keleketla [Give us more!], E rile e le nonwane [It is a tale ], and a reference to the narrator (Nonwanenonwane!) and the listeners (Keleketla!). Some sentences/phrases are repeated slightly or without a reply. The action ends with a concluding formula: Se seo sa mosela seripa! [That is the end of the tale]. The action focuses on a main character, and there may be some repetition of actions (a cycle). The time technique may be used. There is often symbolism. Other features include a song (repeated several times), which brings pleasure and/or pride, and sometimes sorrow. A song may play a role bigger than the narrative. The presence of these factors suggests a legend rather than a historical narrative. The investigation shows that Make does not follow these rules for a legend, but elides actions he thinks the audience/reader already knows, inviting the audience/reader to participate in the narration. That implies that both the narrator and the audience know the 'rules' of a legend Make seems aware that the exposition and conclusion of a legend are based on the use of repetition of formula (a clause, sentence or sentence cluster). In legends, the characters tend to be flat (not rounded) they are interpreted focusing on one idea only (using a phrase or short sentence), which is not a complete depiction of the character. Often the author exaggerates to create humour. This study confirms that flat characters are typical of legends, adding to the artistic structure of this genre. Make successfully uses three techniques (the cycle and journey techniques, and symbolism) in constructing Sello sa Tonki le Pere. A cycle is visible in the repetition of the prosecution of Tonki and Pere to illuminate their case, strengthening and simplifying the sentencing of those animals. Make compares life to a linear journey with a beginning (birth) and a conclusion (death). The phases of the journey symbolise stages of a human life. Make used animals as symbolic characters in this drama to represent real people. Tonki and Pere represent criminals. Kgomo and Nku fight for justice for those mistakenly judged guilty of witchcraft, and they represent the accused. Tau's household represents the capital (Judgement), while Kubu's household represents medicine. A legend should end with a concluding formula: 'Mpho se seo sa mosela seripa!', showing readers/listeners that they can relax, as the narration/fable has come to an end. Make does not use this formula, but ends his fable with 'Pula! Pula! Pula!!'. To explore the structure of a historical drama/narrative, Maloma's drama Marangrang was considered, focusing on the exposition, development, climax and denouement of the drama. In the exposition of Marangrang conflict between Mapulana's children Lethoke, T iane and Madikgake (Mokone of Ma a) who argue over traditional healing (and bravery). This plot suggests the presence of the shadow technique (a shadow focuses on the actions of a character which are similar to actions of another character to be introduced later in the play) (Mojalefa, 1997:35). As a traditional healer Lethoke is a shadow for Marangrang; he stands for Marangrang's actions. By contrast, Madikgake stands for all the tribes. This foreshadows conflict between Marangrang and the Bakgatla, Ma abela, Magolego, Mphahlele tribes. This conflict appeals to the audience/readers, who want to unravel these issues/themes. / Dissertation (MA)--University of Pretoria, 2016. / African Languages / MA / Unrestricted

A MC1R nonsense mutation, R306ter, has been shown to cause a completely yellow coat color in flat coated retriever. A c.916C>T change in the single exon MC1R gene leads to a change from arginine amino acid to a premature stop codon (R306ter). Using DNA sequencing, the polymorphism was found, and genotype and allele frequencies were determined for a selected set of 50 dogs. The frequency of the heterozygous genotype E / e and the undesirable recessive allele e was higher in the selected group in the Czech Republic than we expected.

This is Part B of the Thesis. / <p> The design and performance of a flat emitting ring on-axis electron gun suitable for use in a small reflected beam accelerator was investigated. The design constraints include a low emittance (approximately 5π cm mrad), and a small beam size with a focus approximately 13 cm from the emitting surface.</p> <p> A suitable geometry was determined theoretically and was tested with a dispenser cathode. A beam with a focus at 12.7 ± 1 cm and an emittance of approximately 7π cm mrad was obtained. However, the dispenser cathode response time to heater current changes is too large for the required gun current control.</p> <p> Experiments were done to study the mechanical and thermal properties of flat emitting foil rings, since a directly heated foil has a fast response time. Two foils were tested: 1.27 x 10^-3 cm thick tungsten and 4.57 x 10^-4 cm thick tantalum. The present simple design requires impractically thin foils (≤ 0.25 microns thick) to reach emission temperatures at feasible heater currents.</p> / Thesis / Master of Engineering (MEngr)

<p> Hierarchical leadership structures were once the primary paradigm for leadership in the church. In a contemporary world where culture has shifted and the rise of the scepticism of authority has eroded hierarchies, the church must embrace a new paradigm. Flat leadership is a structure that is being embraced in both the secular world and the church. In this thesis we interpret the shifts in culture and how they have altered the landscape of leadership. We also assess flat leadership as an effective approach to leadership in response to our shifting culture.</p> <p> Flat leadership is a biblical approach to leading. This thesis will engage with Scripture and highlight its support for leading through a sharing of power and authority. Finally, we offer some thoughts on how to begin to move churches from hierarchies to flat structures. Flat leadership represents a Biblical approach to church organizational structures. Utilizing this approach can help churches avoid many of the common pitfalls of ministry and can promote healthier structures for congregational life to thrive.</p> / Thesis / Master of Theological Studies (MTS)

This thesis concerns flat knots and their properties. We study various invariants of flat knots, such as the crossing number, the u-polynomial, the flat arrow polynomial, the flat Jones-Krushkal polynomial, the based matrices, and the φ-invariant. We also examine the behavior of these invariants under connected sum and cabling. We give a matrix-based algorithm to calculate the flat Jones-Krushkal polynomial. We take a special interest in certain subclasses of flat knots, such as almost classical flat knots, checkerboard colorable flat knots, and slice flat knots. We explore how the invariants can be used to obstruct a flat knot from being almost classical, checkerboard colorable, or slice. We show that any minimal crossing diagram of a composite flat knot is a con- nected sum, and we introduce a skein formula for the constant term of the flat arrow polynomial. A companion project to this thesis is the interactive website, FlatKnotInfo. It provides a curated dataset of examples and invariants of flat knots. It also features a tool for searching flat knots and another tool that crossreferences flat knots with virtual knots. FlatKnotInfo was used to develop many of the results in this thesis, and we hope others find it useful for their research on flat knots. The Python code for calculating based matrices and flat Jones-Krushkal polynomials is included in an appendix. / Dissertation / Doctor of Philosophy (PhD)
