Nilpotent Hessenberg varieties are a family of subvarieties of the flag variety, which include the Springer varieties, the Peterson variety, and the whole flag variety. In this thesis I give a geometric proof that the cohomology of the flag variety surjects onto the cohomology of the Peterson variety; I provide a combinatorial criterion for determing the singular loci of a large family of regular nilpotent Hessenberg varieties; and I describe the equivariant cohomology of any regular nilpotent Hessenberg variety whose cohomology is generated by its degree two classes.

Pre-harvest contamination of maize grain with aflatoxin is a chronic problem worldwide and particularly in the southeastern U.S. Aflatoxin is a mycotoxin produced by the fungus Aspergillus flavus, an opportunistic ear-rot pathogen of maize (Zea mays). Resistance to aflatoxin accumulation is heritable, and resistant germplasm-lines are available. These lines are derived from “exotic” genetic backgrounds and were released as sources of resistance, not parental inbreds. However, all current sources of resistance are quantitative, which complicates conventional efforts to introgress resistance alleles from unadapted but resistant donor lines to adapted but susceptible recipient lines. Mapping quantitative trait loci (QTL) and their linked markers enables targeted introgression of the desired alleles via marker-assisted selection. Quantitative trait loci were identified in two F2:3 mapping populations, derived from crossing resistant inbreds Mp715 and Mp717 to a common susceptible parent (Va35). The Mp715 x Va35 population was phenotyped for aflatoxin accumulation under artificial inoculation in replicated field trials at Mississippi State (MSU) in 2015 and 2016. The Mp717 x Va35 population was phenotyped at MSU and Lubbock, TX in 2016. Populations were genotyped using simple sequence repeat (SSR) and single nucleotide polymorphism (SNP) markers and linkage maps created in JoinMap4. To locate QTL, linkage maps, genotypes, and phenotypes were analyzed jointly in QTL Cartographer 2.5 using composite interval mapping (CIM) and multiple interval mapping (MIM) procedures. Five QTL with the beneficial allele contributed by Mp715 were identified during CIM in bins 5.01, 6.06, 7.03 10.04 and 10.05. Three QTL with the beneficial allele contributed by Mp717 were identified during CIM in bins 3.07/3.08, 7.02/7.03, and 10.05. In both populations, QTL were identified with the beneficial allele contributed by Va35. Those QTL did not co-locate across populations but four of the six were on chromosome 1. Significant QTL effects from CIM were used as the initial model terms in MIM, where all QTL effects were fit simultaneously and their gene-action and epistatic interactions estimated.

“Forget me not” is an introspective journey of what it means to belong to a place and can be seen as a process of dealing with the inevitable future of one day losing it. The eminent conditions of inland settlements in northern Sweden and the depopulation raises the question of what will be left behind?  The project explores how the inherent phenomenology of a rather inconspicuous place can be identified, explored, materialized and framed in order to convey its story- creating a memory that remains.  This report presents the true nature of the thesis and process. The theoretical framework on nostalgia, phenomenology of place, architecture and memories, and nostalgia support the work conducted in synthesis. The theoretical and practical explorations are interconnected and together they explore the notion of a particular place and how its characters (genius loci) can generate and inspire new ideas and architecture.

This dissertation focuses on examining the significance of the Qatar University campus as designed by its architect Kamal El Kafrawi. The study takes on a multi-perspective view. The underlying and unifying approach is based on Amos Rapoport's concept of the meaning of the built environment. Rapoport is an architect and scholar, and founder of the field of Environment-Behavior Studies (EBS). Rapoport's early work contrasts 'high culture' design by architects that tends to be self-referential with 'vernacular' buildings by non-architects that respond and speak directly to its users.1 However, I propose to consider El Kafrawi's approach as an exemplary case of bringing both of those aspects together to create an environment that allows buildings (primarily students and faculty) to unfold layers of meaningfulness that the architect intended through a very culturally-sensitive design. This study thus seeks to unearth the meanings associated with the various spaces of the campus areas as built by El Kafrawi and as perceived by its users. The purpose of the project is to find answers to the question, "In what ways and on what basis do people react with their environments, and what meanings and character do those environments develop?"2 Rapoport stresses the meaningfulness of an environment as a key factor that allows inhabitants to feel connected to a place. Author Norberg-Schulz conceptualizes the meaningfulness of the built environment through his theory of Genius Loci as a place with meaning, identity, and history providing a phenomenal or total architectural experience. As per the author, if we consider the physical and symbolic values of the environment, it leads to engagement of human senses at a holistic level - the constructing and construing of architecture. Rapoport outlines a direct approach for the analysis and study of a built environment starting with an assumption that social and cultural factors are the most influential in a built environment. Based on the same concept, the study will critically look at the built environment as designed by El Kafrawi, whether it provides a harmonious blend of culture, traditions, religion, and technology, and whether the amalgamation gives the campus a special meaning and character worthy of the concept of genius loci. Thus, the study aims to unearth the meanings of the thoughtfully designed campus buildings to expose the underlying meaningfulness of the built environment. Rapoport has conducted various studies on the relationships between culture and architecture, notably concerning the influence of environment and behavior, leading to finding the meanings of the environment. He has sought to construct a unified theory on this subject. Rapoport's methods and views will be utilized to identify and investigate the context of this relationship. Based on Rapoport's model, the study will use a three-step approach consisting of dismantling, analyzing, and synthesizing. Firstly, the concepts of culture and the built environment will be identified and dismantled into variables and components according to Rapoport's approach. Then the relationship of these variables with the components and the relationships between the components will be analyzed. Finally, the dismantled and analyzed variables will be gathered and synthesized. Their interrelationships and their ties will be established to understand the significant linkages between forms and their cultural contexts. Integrated with this methodology, the study will look at the meanings of individual design elements from various perspectives and then their integration as a whole to form the character of the built environment. / Doctor of Philosophy / This dissertation explores the Qatar University campus and its significance as designed by architect Kamal El Kafrawi, using a multi-perspective approach based on Amos Rapoport's concept of the meaning of the built environment. Rapoport's idea is that the true meaningfulness of a building is discovered through living with it. The study aims to show how 'living with' the Qatar campus allows inhabitants of the buildings (mainly students and faculty) to unfold layers of meaningfulness that the architect intended in the design of the campus through a very culturally-sensitive design. The study seeks to unearth the meanings associated with the various spaces of the campus areas as built by El Kafrawi and as perceived by its users. The purpose of the project is to find answers to the question, "In what ways and on what basis do people react with their environments, and what meanings and character do those environments develop?" Rapoport's methods and views will be utilized to identify and investigate the context of this relationship. The study will use a three-step approach consisting of dismantling of the designed spaces of the campus, analyzing them, and synthesizing the findings to understand the significant linkages between the designed forms and their cultural contexts. Integrated with this methodology, the study will look at the meanings of these design elements from various perspectives and then their integration as a whole to form the character of the Qatar UniversityCampus. Overall, the dissertation examines how the Qatar University campus reflects a fusion of both contemporary practices and traditional culture through El Kafrawi's approach, bringing together both aspects to create an environment that reflects the meanings and character of the built environment in a culturally-sensitive way. The study aims to contribute to the understanding of the relationship between culture and architecture and how this relationship can be utilized to create a meaningful built environment.

Cette thèse cherche à éclairer les représentations textuelles du « cauchemar », non pas considéré comme un mauvais rêve, mais comme un démon d'origine médiévale. Selon les sources, cet esprit envahit la nuit la chambre de ses victimes. Ensuite, il s'installe sur elles et oppresse leurs poitrines, en provoquant la paralysie, l'étouffement et même la mort des personnes endormies. Cet acte est un motif typique des traditions folkloriques européennes. Dans la tradition gréco-romaine, l' ephialtès et l' incubus semblent agir de la même manière. Notre étude se focalise sur les textes du Moyen Âge, où une abondance de textes divers (ecclésiastiques, littéraires et médicaux) témoigne d'une affinité entre les actions du cauchemar et celles d'un ensemble d'êtres fantastiques, comme les revenants, les elfes, les nains et les sorcières. A la lumière de ces premières constatations, cette étude examine les textes médiévaux en relation avec les traditions antiques, ainsi que les traditions qui apparaissent plus tardivement en Europe. La thèse contient trois parties: dans la première, elle met en évidence un démon -archétypique, qui révèle un substrat étymologique et descriptif commun dans les différents extraits étudiés. Sa relation avec le genius loci, dont le caractère est double, bienveillant et malveillant à la fois, a un intérêt particulier. Les sources dressent le portrait d'un cauchemar qui n'est pas seulement un être démoniaque. En effet, il s'agit également d'un être qui apporte des richesses dans la demeure et à ses habitants. Dans la deuxième partie, la relation du cauchemar avec certaines divinités nocturnes de nature dualiste est démontrée, ainsi que son lien avec les Douze Jours de Noël. Finalement, dans la troisième partie, la thèse étudie un lien général qui apparaît entre le cauchemar, la sorcellerie, le cheval, le carnaval et surtout le Double et les traditions extatiques - chamaniques européennes, afin de signaler en dernier lieu de quelle manière cette entité peut combiner des caractères multiples et différents. / The present Phd Thesis sets to shed light on the topic of the “nightmare”, considered not as a bad dream as it is commonly conceptualized, but instead as a demon of medieval origin. This spirit, said to intrude a room during the night hours, usually sits and exercises pressure on the chest of the alleged victim. This particular act, causing paralysis, drowning, and at times even death to the asleep, is a constant and common narrative motive in the folk stories of Europe. In the Greco-Roman tradition, the “ephialtes” and the “incubus” seem to function in a similar fashion. During the Middle Ages (the period which this study focuses on), an abundance of texts -ecclesiastical, literary, and even medical- suggests a close connection between the nightmare's actions and various super-natural beings, such as revenants, fairies, witches, elves, and dwarves. Drawing from this evidence, this study seeks to examine these texts' relation to the traditions of antiquity, along with the relevant traditions arising later across Europe. The Phd thesis is divided into three main sub-sections: the first part focuses on the relation between different variations of the appearance of an archetypal demon, as revealed by common etymological origins and similar actions. Furthermore, descriptions of the nightmare as a genius loci of two-fold nature, both benevolent and malevolent, are explored. Along with its depiction as a demonic being, the nightmare, is frequently presented as an entity offering treasures to the household and its inhabitants. The second part brings to the forefront nightmare's relation to certain nocturnal deities of dual nature, as well as to the holy season of the Twelve Days of Christmas. During the third and last part of the thesis, I scrutinize the relationship between the nightmare and the horse, the carnival, the witchcraft, and particularly the doppelgänger and the ecstatic-shamanistic practices of Europe.
