Abiotic stress is a major constraint for crop productivity worldwide. To better understand the common biological mechanisms of abiotic stress responses in plants, we performed meta-analysis of 652 samples of RNA sequencing (RNA-Seq) data from 43 published abiotic stress experiments in Arabidopsis thaliana. These samples were categorized into eight different abiotic stresses including drought, heat, cold, salt, light and wounding. We developed a multi-step computational pipeline, which performs data downloading, preprocessing, read mapping, read counting and differential expression analyses for RNA-Seq data. We found that 5729 and 5062 genes are induced or repressed by only one type of abiotic stresses. There are only 18 and 12 genes that are induced or repressed by all stresses. The commonly induced genes are related to gene expression regulation by stress hormone abscisic acid. The commonly repressed genes are related to reduced growth and chloroplast activities. We compared stress responsive genes between any two types of stresses and found that heat and cold regulate similar set of genes. We also found that high light affects different set of genes than blue light and red light. Interestingly, ABA regulated genes are different from those regulated by other stresses. Finally, we found that membrane related genes are repressed by ABA, heat, cold and wounding but are up regulated by blue light and red light. The results from this work will be used to further characterize the gene regulatory networks underlying stress responsive genes in plants. / Master of Science / Abiotic stress is a major constraint for crop productivity worldwide.

The available sources on the dependency action in South Africa do not mention the presence or absence of traditional values. This study was prompted by a simple curiosity to discover the traditional legal values of the dependency action for loss of support. Accordingly, the study critically examines the action of dependants for loss of support and other related losses in South Africa, Botswana and Lesotho from an African perspective. It then compares this to its application in Australia, a country that is known for its recognition and inclusion of indigenous Australian customary law. The study recommends that traditional values should be preserved in the records of the legal system, as it might stimulate a discussion, which could lead to the culmination of a single dependency action tailored to fit the whole nation and all its different cultures and religions. / Private Law

Ausgehend von der Annahme, dass die Ostseeregion primär eine von Städten und urbanen Zentren geprägte Region ist, untersucht diese Studie die Entstehung und Entwicklung grenzüberschreitender Zusammenarbeit von Großstradtregionen im Ostseeraum. Auf der Grundlage poststrukturalistischer Forschungsansätze ergänzt durch Governancetheorien wird ein umfassendes theoretisches Instrumentarium erarbeitet, mit dem drei Fälle grenzüberschreitender Zusammenarbeit von Großstadtregionen aus der Ostseeregion untersucht werden. Die konzeptionelle Grundidee besteht hierbei darin, Vergleichbarkeit nicht durch die Anwendung vorher festgelegter Kriterien, sondern durch die Formulierung und Anwendung eines gleichbleibenden Katalogs offener Forschungsfragen herzustellen. Zunächst werden für diese Arbeit drei Einzelfallstudien zur Öresundregion, Göteborg-Oslo Region und der Euregio Helsinki-Tallinn erstellt. Dann werden in einer vergleichenden Gegenüberstellung Gemeinsamkeiten und Unterschiede erarbeitet und auf dieser Grundlage Faktoren, welche die Entstehung und Entwicklung grenzüberschreitender Zusammenarbeit begünstigen, abgeleitet. Darüber hinaus rückt das Ergebnis der Analyse drei weitere Aspekte für die Entwicklung grenzüberschreitende Zusammenarbeit in den Mittelpunkt, die in angewendeten theoretischen Ansätzen bisher unberücksichtigt geblieben sind, die aber erheblichen Einfluss auf die Entwicklung der einzelnen Region haben: geographische Lage, Timing und Marginalisierung. / Based on the assumption that the Baltic Sea Region is primarily composed of cities and urban areas, this study explores the evolution and development of the cross-border cooperation of large urban areas in the Baltic Sea Region. Using post-structuralist theoretical approaches supplemented with governance theory, the study develops a comprehensive theoretical tool for the analysis of three cases of cross-border cooperation of urban areas in the Balitc Sea Region. The conceptual idea was to safeguard comparability through the application of a common set of open research questions, rather than to apply a set of pre-given criteria. First, this piece of research provides the three single case studies of the Oresund Region, the Gothenburg-Oslo Region and the Euregio Helsinki-Tallinn. Then a comparative analysis elaborates on the commonalities and differences and derives supporting factors for cross-border cooperation based on that background. Finally, the comparative analysis also points to three additional relevant aspects for the development of cross-border cooperation that have not been included into the theoretical approaches but which had remarkable influence on the development of the single cases: geographical localisation, timing and marginalisation.

Esse estudo pretende contribuir para preencher uma lacuna referente à riquíssima teia cultural musical que integra o território brasileiro, bem como em material bibliográfico para professores e alunos do ensino regular.

Cette thèse propose des stratégies de gestion de l'énergie conçues pour un bus urbain électrique hybride. Le système de commande hybride devrait créer une stratégie efficace de coordination du flux d’énergie entre le moteur thermique, la batterie, les moteurs électriques et hydrauliques. Tout d'abord, une approche basée sur la programmation dynamique déterministe (DDP) a été proposée : algorithme d'optimisation simultanée de la vitesse et de la puissance pour un trajet donné (limité par la distance parcourue et le temps de parcours). Cet algorithme s’avère être gourmand en temps de calcul, il n’a pas été donc possible de l’utiliser en temps réel. Pour remédier à cet inconvénient, une base de données de profils optimaux basée sur DP (OPD-DP) a été construite pour une application en temps réel. Ensuite, une technique de programmation dynamique stochastique (SDP) a été utilisée pour générer simultanément et d’une manière optimale un profil approprié de la vitesse du Bus ainsi que sa stratégie de partage de puissance correspondante. Cette approche prend en compte à la fois la nature stochastique du comportement de conduite et les conditions de circulations urbaines (soumises à de multiples aléas). Le problème d’optimisation énergétique formulé, en tant que problème intrinsèquement multi-objectif, a été transformé en plusieurs problèmes à objectif unique avec contraintes utilisant une méthode ε-constraint afin de déterminer un ensemble de solutions optimales (le front de Pareto).En milieu urbain, en raison des conditions de circulation, des feux de circulation, un bus rencontre fréquemment des situations Stop&Go. Cela se traduit par une consommation d'énergie accrue lors notamment des démarrages. En ce sens, une stratégie de régulation de vitesse adaptative adaptée avec Stop&Go (eACCwSG) apporte un avantage indéniable. L'algorithme lisse le profil de vitesse pendant les phases d'accélération et de freinage du Bus. Une autre caractéristique importante de cet algorithme est l’aspect sécurité, étant donné que l’ACCwSG permet de maintenir une distance de sécurité afin d’éviter les collisions et d’appliquer un freinage en douceur. Comme il a été mentionné précédemment, un freinage en douceur assure le confort des passagers. / This PhD thesis proposes Energy Management Strategies conceived for a hybrid electrical urban bus. The hybrid control system should create an efficient strategy of coordinating the flow of energy between the heat engine, battery, electrical and hydraulic motors. Firstly, a Deterministic Dynamic Programming (DDP) based approach has been proposed: simultaneous speed and powersplit optimization algorithm for a given trip (constrained by the traveled distance and time limit). This algorithm turned out to be highly time consuming so it cannot be used in real-time. To overcome this drawback, an Optimal Profiles Database based on DP (OPD-DP) has been constructed for real-time application. Afterwards, a Stochastic Dynamic Programming (SDP) technique is used to simultaneously generate an optimal speed profile and related powersplit strategy. This approach takes into account a stochastic nature of the driving behavior and urban conditions. The formulated energy optimization problem, being intrinsically multi-objective problem, has been transformed into several single-objective ones with constraints using an ε-constraint method to determine a set of optimal solutions (the Pareto Front).In urban environment, due to traffic conditions, traffic lights, a bus encounters frequent Stop&Go situations. This results in increased energy consumption during the starts. In this sense, a relevant Eco Adaptive Cruise Control with Stop&Go (eACCwSG) strategy brings the undeniable benefit. The algorithm smooths speed profile during acceleration and braking phases. One more important feature of this algorithm is the safety aspect, as eACCwSG permits to maintain a safety distance in order to avoid collision and apply a smooth braking. As it was mentioned before, smooth braking ensures passengers comfort.

Die Dissertation besteht aus einem Einleitungsteil und drei empirischen Beiträgen. Die Einleitung gibt eine Einführung in das Themengebiet der Selbstwertschätzung und deren Erfassung mit indirekten Verfahren. Vor allem aber dient sie dazu, die empirischen Befunde der Beiträge zu integrieren. Die ersten beiden Artikel widmen sich der Überprüfung der psychometrischen Qualität indirekter Verfahren. Das Augenmerk des ersten Beitrags liegt auf der Prüfung, ob verschiedene indirekte Verfahren konvergieren und ob explizite und implizite Selbstwertschätzung korrespondieren, wenn implizite Selbstwertschätzung reliabel erfasst wird. Außerdem werden strukturelle Ähnlichkeiten der indirekten Verfahren in die Betrachtungen mit einbezogen. Der zweite Beitrag komplettiert die Untersuchungen zur Güte der Verfahren. Der Fokus dieses Beitrags liegt im Nachweis der prädiktiven Validität verschiedener indirekter Verfahren. Dabei werden Kriterien herangezogen, die nicht im Selbstbericht erhoben werden. Im Detail wird eine doppelte Dissoziation zwischen expliziter und impliziter Selbstwertschätzung geprüft. Der dritte Beitrag rundet diese Arbeit ab, da er sich auch einem anwendungsbezogenen Aspekt der Persönlichkeitspsychologie widmet. Untersucht wird der Zusammenhang zwischen defensiven Verhaltensweisen und Selbstwertdiskrepanzen, also der Kombination expliziter und impliziter Selbstwertschätzung. / The dissertation consists of an introduction and three empirical journal articles. The introduction gives the theoretical background about self-esteem and its assessment with indirect measures, and primarily, integrates the three journal articles. The first article investigates the reliability and convergent and discriminant validity of indirect measures of self-esteem. The second article complements the examination of the psychometric properties. It contributes evidence to the predictive validity of indirect self-esteem measures. With using non-self-reported criteria, a double dissociation between explicit and implicit self-esteem is tested. The third article brings into focus an applied aspect of personality psychology. It is analyzed how defensive reactions are related to self-esteem discrepancies, that are different combinations of explicit and implicit self-esteem.

Testing the Seams of the American Dream: Minority Literature and Film in the Early Cold War delineates the concept of the liberal tolerance agenda in early Cold War. The liberal tolerance message of the U.S. government, the Democratic Party, and others endorsed racial tolerance and envisioned the possibility of a future free from racism and inequality. Filmmakers in often disseminated a liberal message similar to that of the politicians in the form of “race problem” films. My shows how these films and the liberal tolerance agenda as a whole promises racial equality to the racial minority in exchange for hard work, patriotism, education, and a belief in the majority culture. My first chapter, “Washing White the Racial Subject: Hollywood’s First Black Problem Film,” performs a close reading of Arthur Laurents 1946 play Home of the Brave, which features a Jewish American protagonist, in conjunction with a reading of the 1949 film version, which has an African American protagonist. The differences between the two texts reveal the slippages in the liberal tolerance agenda and signal the inability of filmmakers to envision racial equality on the big screen. “The American Institution and the Racial Subject,” my second chapter, discusses the 1949 film Pinky as well as Américo Paredes’s George Washington Gómez and Monica Sone’s Nisei Daughter. All of these works suggests that the attainment of education promises entry into the mainstream by racial minorities, yet Paredes and Sone question this process by interpreting it as resulting in the dual segregation of their protagonists. My third chapter, “Earning and Cultural Capital: The Work that Determines Place,” looks at the promise that with hard work anyone can attain the American Dream. I show how the 1951 film Go for Broke!, Ann Petry’s The Street, and José Antonio Villarreal’s Pocho work to dispel this American myth. My final chapter, “The Regrets of Dissent: Blacklists and the Race Question,” examines the 1954 film Salt of the Earth alongside Chester Himes’s If He Hollers Let Him Go and John Okada’s No-No Boy to reveal the dangerous mixture of race and dissent in this era. / text

A wide literature of predominantly behavioural experiments that use Stimulus Response Compatibility (SRC) have suggested that visual action information such as object affordance yields rapid and concurrent activation of visual and motor brain areas, but has rarely provided direct evidence for this proposition. This thesis examines some of the key claims from the affordance literature by applying electrophysiological measures to well established SRC procedures to determine the verities of the behavioural claims of rapid and automatic visuomotor activation evoked by viewing affording objects. The temporal sensitivity offered by the Lateralised Readiness Potential and by visual evoked potentials P1 and N1 made ideal candidates to assess the behavioural claims of rapid visuomotor activation by seen objects by examining the timecourse of neural activation elicited by viewing affording objects under various conditions. The experimental work in this thesis broadly confirms the claims of the behavioural literature however it also found a series of novel results that are not predicted by the behavioural literature due to limitations in reaction time measures. For example, while different classes of affordance have been shown to exert the same behavioural facilitation, electrophysiological measures reveal very different patterns of cortical activation for grip-type and lateralised affordances. These novel findings question the applicability of the label ‘visuomotor’ to grip-type affordance processing and suggest considerable revision to models of affordance. This thesis also offers a series of novel and surprising insights into the ability to dissociate afforded motor activity from behavioural output, into the relationship between affordance and early visual evoked potentials, and into affordance in the absence of the intention to act. Overall, this thesis provides detailed suggestions for considerable changes to current models of the neural activity underpinning object affordance.

Based on the analyses of the social regulation carried out on the economy field and the political sociology and having as reference the methodological-theoretical frame developed by Marks and fertilized by Gramsci, it was aimed to understand the constitutional determinations of the organization of the school in cycles in Goiânia and questioned in which way they correspond to the processes of regulation of the educational policies or, in the other hand, they can mean a counterpoint to the hegemonic processes of regulation in progress. The investigation in local extent demanded, in addition to the bibliographic research, a process which involved document analysis, interviewing and applying questionnaires in 15 schools. The data obtained from the questionnaires received statistics treatment through the electronic program SPSS - Statistical Package for The Social Sciences. Taking the organization of the school in cycles as a policy in the strict meaning of the state s action, that is, as a policy of the government, it should be considered that it is also found, in higher or lower degree, submitted to the ways of regulation of the policies forged on the lato of the State s action. Thus, the organization of scholarity in cycles in Goiânia can be understood as a policy doubly delimited by regulating processes. As a counterpoint to the organizations in series model, the main changes instituted in the evaluation s extent refer to the variation on the meaning of failing and the introduction of alternatives as regrouping, mobility, rejoining groups or maintenance of some steps. Within the curriculum extent, the speech that it is necessary for the structure to be flexible seems widely absorbed and reaffirmed on the curriculum organized by objectives, by generating theme and work projects, among other methodologies adopted. Inserting new forms and mechanisms of control over the management and organization of work; the emphasis on collective work; the intensification, complexification and teachers work overload have resulted in demand for teachers increasingly more flexible and indicate changes in management and organization of work extents. The organization of schools in cycles in Goiania s educational public schools is a policy whose regulation was expressed by the contradictory movement of flexibilization, which included moments of deregulation/ regulation throughout the period examined. However, what has emerged is that the soothing of flexibilization has not ceased production processes that were made conventional by being called failure at school and for the reasons why more complex forms of social regulations are needed. / Vinculada à Linha de Pesquisa Estado e Políticas Educacionais do Programa de Pósgraduação em Educação da Universidade Federal de Goiás (UFG), esta tese analisa a organização da escola em ciclos em Goiânia à luz dos processos de regulação das políticas educacionais empreendidos no Brasil, particularmente a partir da década de 1990. Com base nas análises da regulação social realizadas no campo da economia e da sociologia política e tendo como referência o quadro teórico-metodológico desenvolvido por Marx e fertilizado por Gramsci, buscou-se apreender as determinações constitutivas da organização da escola em ciclos em Goiânia e interrogar em que sentido elas correspondem aos processos de regulação das políticas educacionais ou, se diferentemente disso, podem significar um contraponto aos processos hegemônicos de regulação em curso. A investigação em âmbito local demandou, além da pesquisa bibliográfica, um processo que envolveu análise documental, realização de entrevistas e aplicação de questionários em 15 escolas. Os dados obtidos dos questionários receberam tratamento estatístico por meio do programa eletrônico SPSS - Statistical Package for The Social Sciences. Ao tomar a organização da escola em ciclos como uma política no sentido stricto da ação estatal, ou seja, como uma política de governo, deve-se considerar que ela também se encontra, em maior ou menor grau, submetida às formas de regulação das políticas forjadas no sentido lato da ação do Estado. Neste sentido, a organização da escolaridade em ciclos em Goiânia pode ser compreendida como uma política demarcada duplamente por processos regulacionais. Contrapondo-se ao modelo de organização seriada, as principais mudanças instituídas no âmbito da avaliação referem-se à variação no significado da reprovação e à inserção de alternativas como reagrupamento, mobilidade, reenturmação ou retenção em algumas etapas. No âmbito do currículo, o discurso de que é necessário flexibilizar sua estrutura parece amplamente assimilado e reafirmado no currículo organizado por objetivos, por tema gerador e projetos de trabalho, dentre outras metodologias adotadas. A inserção de novas formas e mecanismos de controle sobre gestão e organização do trabalho; a ênfase no trabalho coletivo; a intensificação, complexificação e sobrecarga no trabalho dos professores têm resultado na demanda por um professor cada vez mais flexível e são indicativos de mudanças no âmbito da gestão e da organização do trabalho. A organização da escola em ciclos na rede municipal de educação de Goiânia é uma política cuja regulação foi expressa no contraditório movimento de flexibilização, que incluiu momentos de desregulamentação/regulamentação ao longo do período analisado. Entretanto, o que se depreendeu é que o paliativo da flexibilização não tem cessado os processos de produção do que se convencionou denominar de fracasso escolar e em razão do que são necessárias formas cada vez mais complexas de regulação social.
