Essa produção global aumentou aproximadamente 40% ao ano no início da década passada. Esses grandes conjuntos de dados que podem ser capturados, comunicados, agregados, armazenados e analisados, também chamados de Big Data, estão colocando desafios inevitáveis em muitas áreas e, em particular, no campo Machine Learning. Algoritmos de Machine Learning são capazes de extrair informações úteis desses grandes repositórios de dados e por este motivo está se tornando cada vez mais importante o seu estudo. Os programas aptos a realizarem essa tarefa podem ser chamados de algoritmos de classificação e clusterização. Essas aplicações são dispendiosas computacionalmente. Para citar alguns exemplos desse custo, o algoritmo Quality Threshold Clustering tem, no pior caso, complexidade O(�������������5). Os algoritmos hierárquicos AGNES e DIANA, por sua vez, possuem O(n²) e O(2n) respectivamente. Sendo assim, existe um grande desafio, que consiste em processar grandes quantidades de dados em um período de tempo realista, encorajando o desenvolvimento de algoritmos paralelos que se adequam ao volume de dados. O objetivo deste trabalho é apresentar a paralelização do algoritmo de hierárquico divisivo DIANA. O desenvolvimento do algoritmo foi realizado em MPI e OpenMP, chegando a ser três vezes mais rápido que a versão monoprocessada, evidenciando que embora em ambientes de memória distribuídas necessite de sincronização e troca de mensagens, para um certo grau de paralelismo é vantajosa a aplicação desse tipo de otimização para esse algoritmo. / Earlier in this decade there were about 5 billion phones in use generating data. This global production increased approximately 40% per year at the beginning of the last decade. These large datasets that can be captured, communicated, aggregated, stored and analyzed, also called Big Data, are posing inevitable challenges in many areas, and in particular in the Machine Learning field. Machine Learning algorithms are able to extract useful information from these large data repositories and for this reason their study is becoming increasingly important. The programs that can perform this task can be called classification and clustering algorithms. These applications are computationally expensive. To cite some examples of this cost, the Quality Threshold Clustering algorithm has, in the worst case, complexity O (n5). The hierarchical algorithms AGNES and DIANA, in turn, have O (n²) and O (2n) respectively. Thus, there is a great challenge, which is to process large amounts of data in a realistic period of time, encouraging the development of parallel algorithms that fit the volume of data. The objective of this work is to present the parallelization of the DIANA divisive hierarchical algorithm. The development of the algorithm was performed in MPI and OpenMP, reaching three times faster than the monoprocessed version, evidencing that although in distributed memory environments need synchronization and exchange of messages, for a certain degree of parallelism it is advantageous to apply this type of optimization for this algorithm. / 1757857

Främlingskap och annanhet i Diana Gabaldons Främlingen : - En kvalitativ studie ur ett postkolonialt perspektiv

Pehrsson, Amanda January 2022 (has links)
Den här uppsatsen analyserar Diana Gabaldons skönlitterära verk Främlingen. Syftet är att med en kvalitativ textanalys och närläsning analysera hur främlingskap och annanhet gestaltas i boken utifrån ett postkolonialt perspektiv. Annanhet och främlingskap gestaltas genom benämningar gentemot varandra eller inom den egna grupptillhörigheten. Uppsatsen berör hur verket kan kopplas till Skolverkets (2019) ämnessyfte kring litterära föreställningsvärldar i arbetet med litterära diskussioner utifrån Judith A. Langers (2017) perspektiv. Ett postkolonialt perspektiv med fokus på främlingskap kan användas i litterära diskussioner för att vidga elevers föreställningsvärldar där romanen kan analyseras ur ett annat perspektiv än endast utifrån en given genre.

Baumrind's Authoritative Parenting Style: A Model for Creating Autonomous Writers

Payne, Rachel Page 15 March 2013 (has links) (PDF)
Though Quintilian introduced the term in loco parentis in his Institutio Oratoria by suggesting that teachers think of themselves as parents of a student's mind, composition scholars have let parenting as a metaphor for teaching fall by the wayside in recent discussions of classroom authority. Podis and Podis have recently revived the term, though, and investigated the ways writing teachers enact Lakoff's "Strict Father" and "Nurturing Mother" authority models. Unfortunately, their treatment of these two opposite authority styles reduces classroom authority styles to a mutually exclusive binary of two less than satisfactory options. I propose clinical and developmental psychologist Diana Baumrind's taxonomy of parenting styles as the ideal way to reform our thinking as a field about the authority model we should adopt in our writing classrooms. While Baumrind includes the inferior models Podis and Podis work from in her authoritarian and permissive parenting styles, she found that the authoritative style, which is both strict and nurturing, promises the best results for parenting children: autonomy and academic achievement. By applying her descriptions of authoritative parents and the outcomes for their children to the practices of composition instructors and their students, I reveal how useful Baumrind's taxonomy of parenting styles could be for a field that often uses nuanced terms for authority without either clearly defining them or backing claims with replicable, aggregable, data-driven (RAD) research. If our field chooses to adopt Baumrind's terminology and definitions, then, we will be able to communicate about classroom authority in terms anchored in a coherent paradigm and garner more respect for our field as we probe the outcomes of Baumrind's authoritative parenting style as a college composition teaching style through our own empirical research.

Belief And Christmas: Performing Belief And The Theory And Practice Of Christmas Performance

Nicely, Brenna 01 January 2013 (has links)
In the United States, Christmastime has become a time of tension between the holy ideals of family togetherness, childhood innocence, and goodwill towards men and commercial idolatry. Christ and Santa Claus are pitted against each other in the war on Christmas between religion and secularism instead of feasting together on ham and figgy pudding in the traditional fashion. While many would agree that the everyday realities of the Christmas season do not often live up to the ideals imposed upon the holiday, few are able to tell why this is so or even trace the roots of their discontent. In an exploration of the unique anomaly of the hierosecular American Christmas, I propose that the unique systems of Christmas belief extend beyond the usual boundaries of sacred and secular to create a complex web of different beliefs that are performed together to create the unique feeling of Christmas. From a performance theory perspective, I use performance as both traditionally theatrical and as a paradigm for understanding and expressing belief in an effort to explore the essential but elusively defined cultural signifiers of the American Christmas. Through a series of case studies focusing on various traditions of Christmas performance, I apply the performance theories of Diana Taylor, Patrice Pavis, Victor Turner and others to such Christmas staples as Charles Dickens’ A Christmas Carol and Tchaikovsky’s The Nutcracker. In doing so, I propose different points for viewing Christmas and introducing new points of inquiry for questioning the meaning of Christmas, belief, and performance

Estudio de dos experiencias ganadoras del III Concurso Nacional Experiencias Exitosas en Educación Inclusiva 2010

Saavedra Nuñez, María Elena De Los Milagros, Ortega Ordinola, Leidy Diana, Hernández Raffo, Angela 21 August 2014 (has links)
Nuestra investigación, desde el marco de las políticas educativas orientadas a la población peruana con discapacidad, analiza a través de dos casos ganadores, la implementación del “III Concurso Nacional de Experiencias Exitosas en Educación Inclusiva” - 2010, el cual viene dándose por sexto año consecutivo dentro de las actividades realizadas con motivo de la Campaña de Sensibilización y Movilización por la Educación Inclusiva ejecutada por el Ministerio de Educación (MED) a través de la Dirección General de Educación Básica Especial (DIGEBE). Dada la situación de vulnerabilidad de las personas con discapacidad, consideramos conveniente investigar lo avanzado en la implementación de la política educativa dirigida a este sector de la población, dada la importancia de la educación como medio para el desarrollo integral de las personas. Por ello el objetivo central de nuestra investigación es el siguiente: Describir y analizar los factores intervinientes en la práctica docente inclusiva en los dos casos ganadores del III Concurso Nacional de Experiencias Exitosas en Educación Inclusiva – 2010, contrastando los discursos y las prácticas de los docentes y actores involucrados, a fin de elaborar recomendaciones que permitan fortalecer el proceso de educación inclusiva de alumnas y alumnos con necesidades educativas especiales asociadas a discapacidad. En ese sentido, la estructura de la presente investigación es la siguiente: En el primer capítulo presentamos el contexto, la problemática de la educación inclusiva, los objetivos y las hipótesis de la investigación. En el segundo capítulo desarrollamos el marco teórico que sustenta la educación inclusiva para estudiantes con discapacidad. En el tercer capítulo explicitamos la metodología empleada. En el cuarto capítulo, realizamos una breve descripción de cada uno de los casos estudiados en esta investigación. En el quinto capítulo presentamos los hallazgos a los cuales arribamos. Finalmente, en el sexto capítulo, exponemos las conclusiones y las recomendaciones producto de la investigación realizada, las cuales esperamos sean de utilidad para próximas experiencias de educación inclusiva a favor de estudiantes con discapacidad. Se ha comprobado que una actitud positiva de los docentes hacia el proceso de educación inclusiva genera una mejor disposición para educar a estudiantes con NEE asociadas a discapacidad. Asimismo, verificamos que la utilización de estrategias inclusivas innovadoras dentro del aula mejora el proceso de enseñanza –aprendizaje de los estudiantes con NEE asociadas a discapacidad. Finalmente, identificamos que el trabajo coordinado entre el equipo SAANEE, el docente y la comunidad educativa, los padres de familia y la comunidad en general garantiza que el proceso de educación inclusiva tenga buenos resultados. No obstante, en las experiencias estudiadas también se detectó que existen ciertas dispedagogías por parte de los docentes que influyen negativamente en el éxito del proceso inclusivo. / Tesis

So?lo cuento con mi lengua: Hablas pol?ticas y campos en disputa en Tributo del Mudo, de Diana Bellesi, y La Bandera de Chile, de Elvira Hern?ndez

Cossio Arredondo, Germ?n January 2008 (has links)
Tesis para optar al grado de Mag?ster en Estudios Latinoamericanos / El presente ensayo empieza con una confesi?n: la necesidad de declarar que la escritura que se despliega en este trabajo posee una mirada estr?bica; por un lado, este ensayo despliega sus l?neas descriptivas sobre Tributo del mudo, texto po?tico escrito en 1982, por la poeta argentina Diana Bellesi (1946); por otra parte, la atenci?n tambi?n va a recaer sobre otro texto de poes?a, titulado La Bandera de Chile, escrito en 1981, pero publicado con posterioridad, por la poeta chilena Elvira Hern?ndez (1951). Si bien nuestra escritura ir? privilegiando el an?lisis de un texto por sobre otro, incluso separados por cap?tulos independientes, advertimos de entrada que en cada an?lisis rondar? el esp?ritu de la letra del otro texto po?tico, produci?ndose una contaminaci?n intertextual ah? donde centremos nuestra investigaci?n, defraudando a aquel lector que busca en esta escritura una separaci?n tan total como as?ptica de cada texto estudiado. No ha podido ser de otra forma, es m?s, ha sido totalmente conciente y program?tico en tanto hemos querido no s?lo abordar cr?tica y descriptivamente cada uno de estos textos sino adem?s hacerlos dialogar entre s?, entendiendo que di?logo implica establecer sus diferencias as? como explicitar aquellos aspectos que tienden a compartir, en lo textual y contextual. Convergencias y querellas que permiten la emergencia de perspectivas que en general son veladas a la cr?tica cuando ?sta se esmera en no querer salir de la letra misma.

Down to earth : changing attitudes towards nature as reflected in the work of Jenny Cullinan, Lynne Hull and the candidate.

Miller, Diana Mary. January 2001 (has links)
The central purpose of this dissertation is to discuss different ways in which land and the broader natural environment has been used as a vehicle or medium in art-making, with a specific focus on the works of Jenny Cullinan and Lynne Hull and the candidate. The work centres on artworks that are in the landscape, of the landscape, in the earth, of the earth or predominantly concerned with ecological issues and the inter-relatedness of all living systems. It is argued that artworks included under the general appellation land or environmental art may be widely divergent in character, notwithstanding threads of commonality and convergence. In addition, the often fluid or ambiguous nature of the terminology associated with this area of investigation has necessitated some definition of key terms. / Thesis (M.A.)-University of Natal, Pietermaritzburg, 2001.

Fantomen: Från ungkarl till hemmaman : Genuskonstruktioner i äventyrsserien Fantomen av Lee Falk

Hjelm Sandqvist, Carl January 2013 (has links)
In this essay I analyse the constructions of gender in the series The Phantom by Lee Falk. I apply David Tjeders readings of the bourgouise masculinity, its sensitive character and great risk of falling into unmanliness, when discussing The Phantom’s masculine development. I have analysed three adventures of The Phantom from the years 1937, 1977 and 1996, all authored by original creator Lee Falk. I argue that The Phantom increases his use of violence, therefore risking a loss of character. The stories re-establishes his masculinity by portraying the villains more monstrously. My thesis is that The Phantom's need  to maintain a bourgeouis masculinity ceases as the popular culture has developed new masculine ideals.

Variability of unit flexural bond strength and its effect on strength in clay brick unreinforced masonry walls subject to vertical bending

Heffler, Leesa January 2010 (has links)
Masters Research - Master of Philospohy (MPhil) / It has been shown that masonry material properties, in particular, unit flexural bond strength (ft), vary significantly throughout masonry structures, despite the fact that often only one type of brick and mortar are used. Unit flexural bond strength was previously identified as one of the most important material parameters contributing to the strength of clay brick unreinforced masonry (URM) walls in flexure. It was the objectives of this research, in the context of clay brick URM walls subject to vertical bending, to examine how unit flexural bond strength varied spatially in a clay brick URM wall, determine a best fit probability distribution function which can describe expected variability in unit flexural bond strength and determine how this variability and other factors affect wall behaviour and failure load using 3D non-linear finite element analysis (FEA). It was hoped that modelling a full sized clay brick URM wall subject to vertical bending using a 3D non-linear FEA model would more accurately predict wall failure load (compared to current analytical methods) and allow the examination of crack pattern development as the wall progresses to failure upon being laterally loaded. The first part of the research project was to conduct an experimental program to examine unit-to-unit spatial strength correlation within six full sized clay brick URM walls and to characterise a unit flexural bond strength probability distribution. It was observed that although weak correlation in unit flexural bond strength exists in some courses and between courses, these locations were difficult to predict and didn����t follow any particular pattern relating to for example, mortar batch. Therefore, although somewhat counter-intuitive, the results indicate that statistically significant correlation between adjacent unit flexural bond strengths is not likely to be observed. It was also observed that clay brick wall unit flexural bond strengths obtained for all of the walls tested best fit a truncated Normal probability distribution. Strength of the brick/mortar interface appeared to be governed by factors relating to workmanship (and therefore mortar quality and moisture content), weather (which can affect material characteristics like brick suction rate) and inherent material variability. It would appear that brick suction rate can significantly affect the overall strength of a URM wall. v Stochastic analysis was conducted for walls with and without uncorrelated spatial variability in unit flexural bond strength and associated tensile fracture energy (GfI ). It was found that the TNO DIANA 9.2 FEA package could be used to implement spatial variability of various material parameters and reasonably accurately model failure of clay brick URM walls in vertical bending. From the non-linear FEA model development stage, it was observed that because the brick/mortar bond has significantly more strength capacity in compression, it appears that the lateral load resistance of the wall comes from a combination of the ability of the brick/mortar bond to tensile soften while providing significant compressive resistance at the compressive edge. It was found for a spatial stochastic analysis with spatial variability in bond strength (referred to from now on as a spatial stochastic analysis), with COVs of 0.1, 0.3 and 0.5, that COV of wall failure loads were relatively small, being 0.02, 0.04 and 0.06 respectively. For the non-spatially varying stochastic analysis with fully correlated bond strength (now referred to as non-spatial stochastic analysis), with COVs of 0.1, 0.3 and 0.5, COV of wall failure loads were 0.07, 0.20 and 0.32 respectively. For the spatial stochastic analysis, it was found that with a bond strength COV increase from 0.1 to 0.5 the mean wall failure load dropped from 2.25 kPa to 2.0 kPa (an 11% reduction). Despite the relatively small drop in magnitude of the mean wall failure load with increase in bond strength COV, the mean wall failure loads were statistically different to one another. For the non-spatial stochastic analysis, mean failure load stayed relatively constant at 2.24-2.25 kPa. These results could be explained by examining the 3D wall progression to failure. For walls with spatial variability in bond strength, it is expected that wall failure load COVs would be smaller because those walls would consistently be composed of smaller valued bond strengths which would consistently contribute to weakness in the wall. For the non-spatial wall simulations, this effect would not occur as failure load is determined by one uniform weak or strong bond strength. It was proposed that failure of a clay brick URM wall is not governed by one course only cracking, but rather, instability in the wall is governed by several courses in the vicinity of locations of large bending moment. It was shown that various current stochastic approximations which employ a unit failure hypotheses in combination with a linear/elastic approximation for first cracking load all underestimated wall capacity significantly. The reason for this is suggested as being vi because all hypotheses only assume failure is governed by one course and linear/elastic theory only considers the tensile capacity of a joint and neglects strength capacity available as a result of joint tension softening and the resistance to failure provided by compressive strength on the compression side of the wall. The hypotheses also don’t take into consideration factors which affect overall wall bond strength mean which result from influences such as workmanship, weather and material variability factors, such as (for example), variation in brick suction rate due to weather conditions which can make the overall strength of the wall stronger or weaker. Based upon a comparison in wall failure load COV for the spatial and non-spatial stochastic wall analysis results, a more realistic approach for future modelling attempts of spatial variability in masonry material properties is suggested. This would address the issue of external factors such as workmanship and weather on the overall strength of the wall, as well as the inherent bond strength variability due to material variability. For walls with spatial variability in bond strength, upon examination of numerous wall simulation results, several crack patterns were witnessed and are discussed.
