Intercropping of winter maize with forage grasses have been studied because of its benefits in relation to biomass production per area. Objective of this study was to evaluate the interference of density Brachiaria ruziziensis cv. Common intercropped with the winter maize in grain yield, in dry mass and nutrients of forage. The experiment was conducted in soil characterized and Oxiol under conditions of degraded pasture in the Technical School Prof. Luíz Pires Barbosa Cândido Mota city (SP). The experimental desing was randomized blocks with five treatments and four replications. The treatments consisted of the population of B. ruziziensis 2.5; 5,0; 10,0; e 20,0 plants per linear meter and simultaneously sown between the lines of winter maize (0,90m). It was concluded that the values of agronomic evaluation of maize analyzed showed no interference of the treatments, only the height of attachment of spikes was affected by populations of B. ruziziensis; the intercropped presented B. Ruziziensis winter maize with increased grain yeld cereal with a population up to 9,5 plants per linear meter of forage; the total production of dry B. ruziziensis showed higher response to the population at the expense of desiccation in their time of physiological maturity of maize; the accumulation of macro and micronutrients in B. ruziziensis increased as function of the populations with the exception of potassium and iron. / Existe atualmente uma preocupação mundial com a sustentabilidade do agroecossistema, competitividade e viabilidade econômica das atividades agropecuárias. A consorciação do milho safrinha com gramíneas forrageiras tem sido objeto de estudos em decorrência de seus benefícios com relação à produção de fitomassa por área. O objetivo deste trabalho foi avaliar a interferência da densidade de plantas de Brachiaria ruziziensis cv. Comum em consórcio com o milho safrinha na produtividade de grãos, no acúmulo de massa seca e nutrientes dessa forrageira. O experimento foi conduzido em solo caracterizado como Latossolo vermelho eutroférrico em condições de pastagem degradada na Escola Técnica Prof. Luiz Pires Barbosa no município de Cândido Mota (SP). O delineamento experimental utilizado foi o de blocos ao acaso com cinco tratamentos e quatro repetições. Os tratamentos foram constituídos das populações de plantas de B. ruziziensis (2,5; 5,0; 10; e 20) plantas por metro linear semeadas simultaneamente e na entrelinha do milho safrinha (0,90 m). Conclui-se que os valores das avaliações agronômicas analisadas do milho não evidenciaram interferência dos tratamentos, somente a altura da inserção de espigas foi afetada pelas populações de B.ruziziensis; o consórcio de milho safrinha com B.ruziziensis apresentou incremento de produtividade de grãos do cereal com população até 9,5 plantas da forrageira por metro linear; a produção total de massa seca da B. ruziziensis apresentou maior resposta às populações por ocasião da sua dessecação em detrimento da época da maturidade fisiológica do milho; o acúmulo de macro e micronutrientes na B.ruziziensis aumentou em função das populações com exceção do potássio e ferro.

Syftet med den här uppsatsen är att undersöka hur karaktären Amy March porträtterats i olikaadaptioner av Little Women. Utifrån Eders karaktärsklocka med ett fokus på fiktiv existensoch symptom analyseras fyra versioner, de från 1933, 1949, 1994 och 2019. Genom att utgåfrån ett genusperspektiv undersöks även hur tiden varje adaption gjorts under formatkaraktären. Resultatet av analysen visar att de två tidigare adaptionerna följer merkonventionella genrekonventioner där Jo står i fokus. De två senare adaptionerna ger merplats åt Amy och ger en mer nyanserad bild av karaktären. Dessutom för de uppmärksamhetentill den verklighet som kvinnor levde i under 1800-talet och har tydliga feministiska budskap.

The purpose with this study is to examine the description of native Americans in two novels, Old Surehand part 1 and 2 by the German author Karl May. By using a postcolonial theory, descriptions of people from different Native American nations have been studied, to see how these are portrayed by May and if there are any differences between the descriptions of different nations. The results of this study have shown that the descriptions differ between different native American nations. The Apache are positively defined, and the narrated picturesare clearly influenced by the description of the figure Winnetou, the chief of the Apache and a good friend to the main character Old Shatterhand. Other nations can be narrated as enemies and as warlike. They become however more positively pictured when they create a contact with and befriend Old Shatterhand, where the Comanche Nation can be seen as such an example. The descriptions of the native Americans are focused on their looks and appearance,as well as their traits and qualities, and are often rendered stereotyped. Finally, it becomes clear that a postcolonial perspective emerges, in which characters aredivided into “the own” and “the others”. However, it is not uncommon for the maincharacter Old Shatterhand, to have a seemingly positive bias in reaching out to the Native Americans. When that occurs, he is actually acting against a post-colonial stance.

In response to Irish philosopher Richard Kearney’s recent proposal of a post-metaphysical re-imagination of God, the thesis asks how we may begin to reimagine the Christ-event, post-metaphysically. Specifically, it investigates the implications of such post-metaphysical thought for the theological categories of hamartiology and soteriology. Methodologically, the thesis proceeds from hermeneutical re-readings of biblical narratives and traditions. Via an archaeology of the biblical yetser, the concept of imagination is offered as a way to re-imagine sin and salvation. The Eden narrative is read within its ancient Near Eastern context, and the narratives of the Annunciation and Transfiguration also receives special mention, as well as the window that Song of Songs opens on the metaphor of the desire of God. What results from this approach is, first, yet another deconstruction of the Augustinian formulation of original sin, as well as an eschatological reinterpretation of the Christ event in terms of the messianic Kingdom of God. Christ, who submits his yetser to the will of the Father in an act of worshipful surrender, becomes the perfect embodiment of the Word of God to a humanity whose yetser is perpetually put in service of itself in an act of idolatry. The enabling of the Kingdom of God in Jesus, who embodies the human telos, captures the human imagination and transfigures humanity through the existential experience of transcendence which breaks into its concrete reality through the Christ-event and its retelling. In this way, realised eschatology is possibilised through the imagination. Christ as prototype of the divinely intended telos of humanity becomes an existential possibility via the transfiguration, enacted by the imagination. This enables humanity to become co-creators with God of a new creation, symbolised by God’s messianic Kingdom of love and justice. / Thesis (PhD)--University of Pretoria, 2016. / University of Pretoria Postgraduate bursary / Dogmatics and Christian Ethics / PhD / Unrestricted

This dissertation examines how Concord, Massachusetts became a heritage town in the nineteenth and early twentieth centuries. Concord-based authors (including Ralph Waldo Emerson, Nathaniel Hawthorne, Henry David Thoreau, and Louisa May Alcott) at once contributed to Concord’s attractiveness as a location and took advantage of the growing reputation and popularity of the town as a tourist site. Their writings, rooted in Concord, drew attention to the town and to themselves as authors within it, while also elevating the stature of American literature. Linking literature and site-building, Concordians encouraged contemporaneous sightseeing in a curated landscape. This sets the origins of tourism and site-building in Concord earlier than standard academic narratives of Progressive Era preservation in New England. The primary contribution of this interdisciplinary study is to trace the ways in which collective memory was fashioned for an audience of literary “arm-chair travellers” and then employed to endow private houses with literary and historical importance to national heritage, as public locations to be visited and preserved in Concord’s landscape. This work traces the development of spiritualized “places” in Concord from Revolutionary War monument-building to Emerson’s literary community investing the landscape with poetic associations, Hawthorne’s engagement of tourism as an appeal to readers, and George William Curtis’s efforts to market Concord as a national literary retreat. It further examines Thoreau’s literary career in relation to his interest in local history, tourism, and museum-building in his hometown. Finally, the popularity of Alcott’s Little Women boosted tourism in Concord, and the increase of visitors coincided with projects to memorialize Thoreau, Hawthorne, and the Transcendentalist movement in the landscape. These efforts culminated in the development of guide books and organized tours for visitors, and the emergence of a local souvenir industry. The study concludes with the institutionalization of historic house museums in the early twentieth century.

Der vorliegenden Studie Die dialektische Lebenskunst von Guy Debord, Verworfener & Kulturschatz liegt eine interdisziplinäre Untersuchung des Gesamtwerks jenes französischen Radikalen zugrunde. Debords kohärentes Bestreben hatte darin bestanden, zu einer Leidenschaft der Existenz zurückzufinden, wie sie als Grundlage zur Umwälzung des verarmten Alltagslebens dienen sollte. Zugleich Ehre und Pläsier war es ihm dabei, der „Gesellschaft des Spektakels“ - 1967 in einem strategisch eingesetzten ‚Theoriebuch‘ in Form von Zweckentfremdungen analysiert - zu schaden, wo er nur konnte. Kategorisierungsversuche seiner Tätigkeiten und Umtriebe ‚unterlief‘ der Wahlpariser regelmäßig. Lediglich den Einordnungen als Filmemacher und Enragé stimmte er zu. Interpretationsschwerpunkte liegen auf der Begutachtung von Bildmanifesten und Selbstporträts, wozu seine sieben Filme zählen. Im Rahmen eines an Gerald Raunig und Bazon Brock angelehnten Theoriedesigns, wird sein provokantes Vorgehen in neun Kapiteln (I – IX) als Gesamtkunst-Experiment und Lebenskunstwerk beschrieben. Fundamental ist hierbei das Diktum Brocks, dass ein Totalkunstwerk ein Postulat seiner eigenen Verwirklichung darstellt. Die Gliederung des Stoffes folgt dem romanhaften Werdegang eines Initiators zweier Avantgardeformationen sowie dem Vollzug einer ‚Überwindung‘ der Kunst in deren Reihen. Das Gravitätszentrum aller Aktivitäten und ein Scharnier der Abhandlung ist die klandestine Rolle, welche die Situationistische Internationale bei der Verwirklichung der Mai-Revolte 1968 in Frankreich spielte. / In its character the study Guy Debords Art of Living, Accursed Poet & Cultural Treasury is an interdisciplinary examination of this French radical’s strange and obscure ways. His coherent achievement may be judged as an approach to regain a lost passion of existence in order to revolutionize everyday life. Debord found pleasure and pride in his lifelong ambition to demolish the so-called “Socitey of the Spectacle”, which he analyzed in his infamous book by the same title, first published in 1967. Often quoted since, rarely described as the invention and event it was. Debord defended himself againt categorization. But he agreed on being titulated a filmmaker and enraged person in the tradition of a perverted French Revolution. Following a theory-design, paying references to Gerald Raunig and Bazon Brock, his provocative approach is discussed in nine chapters (I-IX). Baring in mind that – according to Brock – a total work is a postulate of its own realization. The script follows the novel-like progress of a co-founder and lustful destroyer of two avantgarde-troups. All of the group activities are gravitating around what happened in Paris at the heyday of May 68.

Le but de cette thèse est de présenter une vue d’ensemble du Traité constitutionnel européen, et d’apporter une explication quant à son rejet par une majorité d’électeurs français lors du référendum tenu le 29 mai 2005. Dans un premier temps, nous présenterons les fondements et principes de cette constitution, mais aussi certaines idées faisant débat au sein de l’Union européenne afin d’en comprendre les enjeux. Ensuite, nous considérerons des points de vue partagés ou divergents parmi les partis et les politiciens qui ont appelé à voter NON parmi la gauche, l’extrême gauche, la droite et l’extrême droite. Enfin, nous tâcherons de tirer des conclusions quant aux divers arguments afin de comprendre quels ont été les points communs de tous ces partis et les raisons principales de ce malaise créant finalement ce besoin d’unité nationale profonde parmi la population française.

Since the 1970s we have witnessed a flourishing of transitional justice efforts around the globe. Yet, the actual impact of transitional justice is in question. This study assesses the impact of transitional justice with a single-case study of South Korea, the May 18 Democratic Movement (5.18) case in particular. In addition to the impact assessment, my dissertation provides an explanation on how transitional justice mechanisms exert their impact. To assess the impact of transitional justice, the study examines three dimensions - civil-military relations, historical narratives and institutional safeguards against human rights violations – which are essential in deterring further human rights violations by states. After process tracing the evolution of each dimension for the last 36 years, the study finds that transitional justice in South Korea has had a positive impact on deterring human rights violations since the democratic transition: the impact on civil-military relations and historical narratives is strong and positive, and the impact on institutional safeguards is positive, but somewhat limited due to South Korea’s unique security circumstances. Although the implementation of transitional justice mechanisms was imperfect and their impact is limited in some domains, on balance, the benefits of pursuing transitional justice in the South Korean case outweighed any possible costs – benefits in terms of (1) strengthening civilian control over the military, (2) creating a new historical narrative that delegitimated human rights abuses, and (3) creating institutional safeguards against human rights violations. Despite the possible negative consequences, the South Korean experience suggests that if transitional justice is pushed by strong public demand and properly implemented (sequence, timing, etc.), it can actually be more profitable and fruitful in establishing a society in which human rights are well respected and protected. The study also finds that transitional justice is a long and non-linear process, and not only the outcome but also the process itself produces a positive impact. / 2025-11-30T00:00:00Z

We study the fluctuation effects in the seminal cyclic predator-prey model in population dynamics due to Robert May and Warren Leonard both in the zero-dimensional and two-dimensional spatial version. We compute the mean time to extinction of a stable set of coexisting populations driven by large fluctuations. We see that the contribution of large fluctuations to extinction can be captured by a quasi-stationary approximation and the Wentzel–Kramers–Brillouin (WKB) eikonal ansatz. We see that near the Hopf bifurcation, extinctions are fast owing to the flat non-Gaussian distribution whereas away from the bifurcation, extinctions are dominated by large fluctuations of the fat tails of the distribution. We compare our results to Gillespie simulations and a single-species theoretical calculation. In addition, we study the spatio-temporal pattern formation of the stochastic May--Leonard model through the Doi-Peliti coherent state path integral formalism to obtain a coarse-grained Langevin description, i.e. the Complex Ginzburg Landau equation with stochastic noise in one complex field. We see that when one restricts the internal reaction noise to small amplitudes, one can obtain a simple form for the stochastic noise correlations that modify the Complex Ginzburg Landau equation. Finally, we study the effect of coupling a spatially extended May--Leonard model in two dimensions with symmetric predation rates to one with asymmetric rates that is prone to reach extinction. We show that the symmetric region induces otherwise unstable coexistence spiral patterns in the asymmetric May--Leonard lattice. We obtain the stability criterion for this pattern induction as we vary the strength of the extinction inducing asymmetry. This research was sponsored by the Army Research Office and was accomplished under Grant Number W911NF-17-1-0156. / Doctor of Philosophy / In the field of ecology, the cyclic predator-prey patterns in a food web are relevant yet independent to the hierarchical archetype. We study the paradigmatic cyclic May--Leonard model of three species, both analytically and numerically. First, we employ well--established techniques in large-deviation theory to study the extinction of populations induced by large but rare fluctuations. In the zero--dimensional version of the model, we compare the mean time to extinction computed from the theory to numerical simulations. Secondly, we study the stochastic spatial version of the May--Leonard model and show that for values close to the Hopf bifurcation, in the limit of small fluctuations, we can map the coarse-grained description of the model to the Complex Ginsburg Landau Equation, with stochastic noise corrections. Finally, we explore the induction of ecodiversity through spatio-temporal spirals in the asymmetric version of the May--Leonard model, which is otherwise inclined to reach an extinction state. This is accomplished by coupling to a symmetric May-Leonard counterpart on a two-dimensional lattice. The coupled system creates conditions for spiral formation in the asymmetric subsystem, thus precluding extinction.
