Dramatic structure in the photodetachment of inner shells of negative ions: Li-

Deep inner-shell photodetachment of negative ions is shown to differ qualitatively and quantitatively from the corresponding process in neutral atoms and positive ions. As an example, calculations of the photodetachment of Li- out of the 1s shell, using an augmented R-matrix methodology, are presented and show numerous structures over a broad energy region including a new phenomenon: Auger decay of a shape resonance. Li- was selected because it is the simplest multishell negative ion and is amenable to experimental scrutiny.

A poética do sublime na teoria da tragédia de Friedrich Schiller

Em sua breve carreira filosófica, o poeta e dramaturgo alemão Friedrich Schiller (1759-1805) se apropriou do conceito kantiano do sublime, identificando-o ao trágico e à tragédia, manifestação artística que seria genuinamente regulada por princípios estéticos daquela ordem. Deste modo, buscamos neste trabalho relacionar o caráter subjetivo da experiência do sublime com as suas implicações de ordem prática para a arquitetura da tragédia, em especial as que dizem respeito à estrutura ideal do drama, intimamente vinculada à sua finalidade, que é a efetivação do efeito estético que lhe cabe por definição. Se, por uma via, o pensamento de Schiller caminha em direção ao desenvolvimento de uma concepção do trágico a partir de um dos conceitos fundamentais da estética moderna, por outra ele permanece atrelado à tradição aristotélica quando se concentra no estudo da tragédia enquanto gênero literário e busca por meio deste estudo estabelecer regras para a citação dramatúrgica. Assim, Schiller constrói uma poética do sublime, um programa de arte que inaugura um debate importante sobre o fenômeno do trágico na filosofia alemã. Mas, como pretendemos defender, é justamente a concepção do trágico forjada a partir de uma interpretação acentuadamente moral do sublime que torna o conteúdo de sua teoria da tragédia problemático, embora tal teoria seja a resposta encontrada por Schiller para perguntas ainda pertinentes. Afinal, por que nos entretêm assuntos trágicos?

Heróis a contrapelo: lampejos do gênio na escrita dos jovens Goethe e Schiller

O estilo de época Sturm und Drang, o primeiro movimento literário genuinamente alemão, surgido na segunda metade do século XVIII, possibilitou a emancipação literária da Alemanha e introduziu naquele país o conceito de gênio original. A partir da descoberta da obra do gênio inglês Shakespeare (possibilitada pelas traduções de Christoph Martin Wieland), os alemães se depararam com o modelo de revolução literária que necessitavam para instituir as bases da originalidade literária alemã. Pautando-se na estrutura dramática shakespeariana, Johann Wolfgang von Goethe e Friedrich Schiller elaboraram seus dramas de estreia, obras foco da presente pesquisa: Götz von Berlichingen e Os bandoleiros, respectivamente. O presente estudo propõe-se, por conseguinte, a analisar as obras supracitadas à luz da temática do gênio original. Mas, primeiramente, são observados os fatores (como a ascenção do romance inglês) e escritores (como Gothold Ephraim Lessing, Johann Jakob Bodmer, Johann Jakob Breitinger, Friedrich Gottlieb Klopstock, Johann Joachim Winckelmann, Wieland e Johann Gottfried von Herder) que colaboraram para a instituição da era genial na Alemanha

Ensaio sobre as imagens. A criação do roteiro de Blindness de Fernando Meireles, adaptado do romance: Ensaio sobre a cegueira de José Saramago para as telas de cinema

A dissertação se propõe a investigar as diferentes formas de estruturas narrativas para o desenvolvimento em um roteiro cinematográfico, adaptado de uma obra literária. Para este trabalho, vamos usar como corpus o romance Ensaio sobre a cegueira de José Saramago que foi adaptado pelo roteirista Don Mckellar, originando o filme dirigido por Fernando Meirelles, em 2008. A finalidade deste recorte é mostrar o processo de construção narrativa no audiovisual, tendo como base o livro. Nessa investigação, o suporte para análise do audiovisual será realizado com conceituados especialistas em roteiros cinematográfico como Linda Hutcheon, Robert Mckee, Jean-Claude Carriére, Flávio de Campos e David Howard. As possibilidades da criação do roteiro seguirão o mote em quatro divisões: narrativa, estrutura, ensaio sobre imagens e da palavra para imagem, procurando responder como a linguagem intervém no sentido da palavra para imagem e como ocorre o conceito de autoria nessa vertente da adaptação. A trama de Ensaio sobre a cegueira, traz elementos clássicos da estrutura dramática e amplia sua dimensão em relação ao conteúdo da estória na roteirização de Don Mckellar. Com esta pesquisa, esperamos contribuir para um melhor entendimento na construção e organização de um roteiro no processo de adaptação em si

Le Banquet de Platon : l'apologie d'Alcibiade ou les paradoxes d'Éros

Ce mémoire cherche à évaluer la culpabilité de Socrate face à l’échec et à la corruption d’Alcibiade, telle que la question se pose dans le Banquet de Platon. Il comprend quatre chapitres. Le premier démontre que le cadre dramatique lui-même fait occuper une place centrale à la vie et au déclin d’Alcibiade et au problème de la responsabilité de Socrate face aux accusations de corruption de la jeunesse qui ont pesé sur lui. Le deuxième chapitre interprète le discours d’Alcibiade comme une tentative de disculpation qui repose sur une critique acerbe du comportement de Socrate. Il se serait détourné de Socrate et de ses enseignements en raison de son ironie, de son arrogance et de son indifférence – de son hybris. Le troisième chapitre étudie le discours de Socrate sur l’accession à la beauté intelligible. Il expose la nature particulière de son éros, qui repose sur l’ironie et l’inversion des rôles comme moyens d’exhorter à la philosophie. Le quatrième chapitre pose la question de l’efficacité de ce type de pédagogie et de la responsabilité du philosophe vis-à-vis de ses disciples. L’étude conclut que l’amour et l’ironie de Socrate sont essentiellement des moyens d’inviter l’autre à se remettre lui-même en question et à prendre soin de son âme. Socrate n’est donc pas coupable d’avoir corrompu Alcibiade. La faute est entièrement celle du jeune homme. Il s’est montré incapable, par égocentrisme et fierté excessive, de réagir correctement à l’énigme posée par le comportement érotique de Socrate.

Vénus et Neptune en Crète : la fonction dramatique des divinités dans Idoménée de Danchet et Campra.

Ce mémoire porte sur le rôle des divinités dans la structure dramatique de la tragédie en musique Idoménée d’Antoine Danchet et d’André Campra, originalement créée en 1712 et remaniée en 1731. L’étude répond à des questions d’ordre structurel quant à l’évolution du genre et montre de quelle façon la représentation des dieux dans Idoménée est liée à une ouverture formelle qui annonce la disparition du prologue, puisque les divinités n’y sont plus confinées à une fonction de louange du roi, mais contribuent activement à lancer l’action dramatique dès cette partie liminaire de l’opéra. Par un bref aperçu historique de la tragédie lyrique et des traditions mythologiques se rapportant à Vénus et à Neptune, ce mémoire questionne la place de ces dieux dans l’univers des hommes, tel que l’envisage la tragédie lyrique, qui démontre, comme on le sait, une propension à unifier les mondes surnaturel et humain. Dans Idoménée, cette unification passe en grande partie par l’usage d’un prologue qui fait office de premier acte, en assurant aux divinités en question une fonction essentielle à la structure dramatique.

Ficción y periodismo audiovisual: Un primer plano a la fuga y muerte de Pablo Escobar Gaviria

La fuga y la muerte de Pablo Escobar fueron dos acontecimientos que contaron con un importante cubrimiento por parte de los noticieros CM& y NTC. Años después, la ficción, a través del cine y la televisión nacional, se encargó de representar ambos hechos (primero con la película Apocalipsur y luego con la serie El cartel). Al comparar las narrativas ficcionales con las periodísticas se encontró que la estructura dramática podía estar presente en ambas, tanto en las escenas de los dramatizados, como en las noticias. Sin embargo, se identificaron diferencias en cuanto a la omisión de personajes, las clases de montaje, los escenarios utilizados y en general la manera en que el contenido y la forma cambia en cada formato. Al final, es el pacto de veracidad, o de verosimilitud, lo que determina la relación entre el espectador y el producto audiovisual.

Trevor Griffiths' 'Absolute Beginners': socialist humanism and the television studio

This article examines how conventional studio production strategies were active in the construction of political meaning in the 1974 television play 'Absolute Beginners' written by Trevor Griffiths. Produced for the BBC anthology series Fall of Eagles, the play dramatises Lenin's involvement with the Russian Social Democratic Workers Party (RSDWP) and explores the contradictions between personal ethics and political necessity. Through close textual analysis and contextual discussion of other plays in the series, this piece demonstrates how shot patterns and spatial and performative devices in 'Absolute Beginners' supported the drama's socialist-humanist themes. Drawing on existing writing about the studio mode, it argues that the qualities of intimacy and presentational distance that it engendered were highly appropriate for the personal and the political dialectic in 'Absolute Beginners'. While using authorship as a convenient category for referring to the coherence of Griffiths' thematic concerns and dramatic structure during this period, the article complicates notions of the television dramatist as author by arguing for the importance of visual style and showing how 'ordinary' studio form was operational in the play's political meanings.

Filmmusikens betydelse : En receptionsstudie om hur musik i film bidrar till förståelse

This essay is about film music and how people react in a study where the music and picture comes from two different genres that both has unique conventions, of how the “standard” music ought to be composed. The purpose of this essay is mainly to try and get an understanding of film music’s importance in the movies dramatic structure, and how people react when the conventions of music is broken and two genres are combined into one.The questions that are to be answered in this essay are: *how could music as a tool change the character of a film? *How does the participants, of this inquire, experience the film depending on what music they hear? *And what is it that the participants think that the music brings to the movies narration?The method of this survey is based on a number of participants that have responded on questions of how they experienced the movie, both with music and without. This study has shown that when music and picture, which comes from different genres, interact with each other it tends to create comical features and a sense of that the music has an advantage in terms of the genre that people feel that the film has.

Plato's Cretan Colony: Theology and Religion in the Political Philosophy of the Laws

The Laws is generally regarded as Plato’s attempt to engage with the practical realities of political life, as opposed to the more idealistic, or utopian, vision of the Republic. Yet modern scholars have often felt disquieted at the central role of religion in the Laws’ second-best city and regime. There are essentially the two dominant interpretations on offer today: either religion supports a repressive theocracy, which controls every aspect of the citizens’ lives to such an extent that even philosophy itself is discouraged, or religion is an example of the kind of noble lie, which the philosopher must deceive the citizens into believing—viz., that a god, not a man, is the author of the regime’s laws. I argue that neither of these interpretations do justice to the dialogue’s intricately dramatic structure, and therefore to Plato’s treatment of civil religion. What I propose is a third position in which Plato both takes seriously the social and political utility of religion, and views theology as a legitimate, and even necessary, subject of philosophical inquiry without going so far as to advocate theocracy as the second best form of regime.

I conclude that a proper focus on the dialogue form, combined with a careful historical analysis of Plato’s use of social and political institutions, reveals an innovative yet traditional form of civil religion, purified of the harmful influence of the poets, based on the authority of the oracle at Delphi, and grounded on a philosophical conception of god as the eternal source of order, wisdom, and all that is good. Through a union of traditional Delphic theology and Platonic natural theology, Plato gives the city of the Laws a common cult acceptable to philosopher and non-philosopher alike, and thus, not only bridges the gap between religion and philosophy, but also creates a sense of community, political identity, and social harmony—the prerequisites for political order and stability. The political theology of the Laws, therefore, provides a rational defense of the rule of law (νόμος) re-conceived as the application of divine Reason (νοῦς) to human affairs.

'Scratch' locative audio drama - report to BBC executives on trial at BBC FreeThinking 2008

‘Scratch’ investigates the use of physical space as a representation of narrative and dramatic structure. An audio-drama, it is a world-first in being location-sensitive without being tied to any particular place (preceding attempts by others have emphasised location-specific aspects of the genre). Developed in collaboration with and part-funded by BBC Radio Drama, it builds on research undertaken for ‘Dragons’ (output 4). It uses pre-recorded audio on GPS-enabled mobile devices allowing sounds to be virtually attached to locations in an outdoor space. As participants move, they encounter scenes forming a coherent drama which behave differently if the same place is visited more than once. This translocational approach opens novel artistic possibilities exploited through team expertise in narrative, sound design and advanced interaction. It is also significant in the economics of broadcast media as a more viable proposition than the many experimental locative experiences which have been site-specific: this was of great interest to the BBC. The public performance selected for BBC FreeThinking, 1-2 September 2008 in Liverpool as part of European Capital of Culture was reported in a co-authored 2009 conference presentation at ISEA, Belfast, 26-29 August 2009 and in a co-authored short chapter in Spierling and Szilas (eds.) Interactive Storytelling, Springer 2008. Boyd Davis directed the project and devised and undertook the evaluation with 40 trial listeners, reporting to BBC executives (http://researchonline.rca.ac.uk/1000/) for whom a second trial was also run in London in 2009. The evaluation used interview, video observation and a questionnaire combining an open question at the beginning with more specific questions later, avoiding channelling respondents' reactions immediately after the experience into issues which might not be uppermost in their minds, while also yielding data capable of rigorous analysis. The evaluation was to provide feedback to the makers of the drama and to guide policy at the BBC. [287] Participants were recruited principally through the publicity for FreeThinking 2008 – mainly via the festival website. The average age of participants was 40. The gender of participants was 20 males, 17 females and 3 null returns. The evaluation strategy was to combine an open question at the beginning with more specific questions later. In this way we avoided channeling respondents' initial opinions immediately after the experience into issues which might not be uppermost in their minds, while also yielding data capable of rigorous analysis. The purpose of the evaluation was to provide guidance for ourselves as the makers of the drama and to guide policy at the BBC on locative and other interactive media. The responses are analysed in the report.

Structure and function of DsbA, a key bacterial oxidative folding catalyst

Since its discovery in 1991, the bacterial periplasmic oxidative folding catalyst DsbA has been the focus of intense research. Early studies addressed why it is so oxidizing and how it is maintained in its less stable oxidized state. The crystal structure of Escherichia coli DsbA (EcDsbA) revealed that the oxidizing periplasmic enzyme is a distant evolutionary cousin of the reducing cytoplasmic enzyme thioredoxin. Recent significant developments have deepened our understanding of DsbA function, mechanism, and interactions: the structure of the partner membrane protein EcDsbB, including its complex with EcDsbA, proved a landmark in the field. Studies of DsbA machineries from bacteria other than E. coli K-12 have highlighted dramatic differences from the model organism, including a striking divergence in redox parameters and surface features. Several DsbA structures have provided the first clues to its interaction with substrates, and finally, evidence for a central role of DsbA in bacterial virulence has been demonstrated in a range of organisms. Here, we review current knowledge on DsbA, a bacterial periplasmic protein that introduces disulfide bonds into diverse substrate proteins and which may one day be the target of a new class of anti-virulence drugs to treat bacterial infection.

Side Chain Structure Determines Unique Physiologic and Therapeutic Properties of norUrsodeoxycholic Acid in Mdr2(-/-) Mice

24-norursodeoxycholic acid (norUDCA), a side chain-modified ursodeoxycholic acid derivative, has dramatic therapeutic effects in experimental cholestasis and may be a promising agent for the treatment of cholestatic liver diseases. We aimed to better understand the physiologic and therapeutic properties of norUDCA and to test if they are related to its side chain length and/or relative resistance to amidation. For this purpose, Mdr2-/- mice, a model for sclerosing cholangitis, received either a standard diet or a norUDCA-, tauro norursodeoxycholic acid (tauro- norUDCA)-, or di norursodeoxycholic acid (di norUDCA)-enriched diet. Bile composition, serum biochemistry, liver histology, fibrosis, and expression of key detoxification and transport systems were investigated. Direct choleretic effects were addressed in isolated bile duct units. The role of Cftr for norUDCA-induced choleresis was explored in Cftr-/- mice. norUDCA had pharmacologic features that were not shared by its derivatives, including the increase in hepatic and serum bile acid levels and a strong stimulation of biliary HCO3- -output. norUDCA directly stimulated fluid secretion in isolated bile duct units in a HCO3- -dependent fashion to a higher extent than the other bile acids. Notably, the norUDCA significantly stimulated HCO 3- -output also in Cftr-/- mice. In Mdr2-/- mice, cholangitis and fibrosis strongly improved with norUDCA, remained unchanged with tauro- norUDCA, and worsened with di norUDCA. Expression of Mrp4, Cyp2b10, and Sult2a1 was increased by norUDCA and di norUDCA, but was unaffected by tauro- norUDCA. Conclusion:The relative resistance of norUDCA to amidation may explain its unique physiologic and pharmacologic properties. These include the ability to undergo cholehepatic shunting and to directly stimulate cholangiocyte secretion, both resulting in a HCO3- -rich hypercholeresis that protects the liver from cholestatic injury.

Effects of management and landscape structure on biodiversity in boreal agricultural farmland

Intensified agricultural practises introduced after the Second World War are identified as a major cause of global biodiversity declines. In several European countries agri-environment support schemes have been introduced to counteract the ongoing biodiversity declines. Farmers participating in agri-environment schemes are financially compensated for decreasing the intensity of farming practises leading to smaller yields and lower income. The Finnish agri-environment support scheme is composed of a set of measures, such as widened field margins along main ditches (obligatory measure), management of features increasing landscape diversity, management of semi-natural grasslands, and organic farming (special agreement measures). The magnitude of the benefits for biodiversity depends on landscape context and the properties of individual schemes. In this thesis I studied whether one agri-environment scheme, organic farming, is beneficial for species diversity and abundance of diurnal lepidopterans, bumblebees, carabid beetles and arable weeds. I found that organic farming did not enhance species richness of selected insect taxa, although bumblebee species richness tended to be higher in organic farms. Abundance of lepidopterans and bumblebees was not enhanced by organic farming, but carabid beetle abundance was higher in mixed farms with both cereal crop production and animal husbandry. Both species richness and abundance of arable weeds were higher in organic farms. My second objective was to study how landscape structure shapes farmland butterfly communities. I found that the percentage of habitat specialists and species with poor dispersal abilities in butterfly assemblages decreased with increasing arable field cover, leading to a dramatic decrease in butterfly beta diversity. In field boundaries local species richness of butterflies was linearly related to landscape species richness in geographic regions with high arable field cover, indicating that butterfly species richness in field boundaries is more limited by landscape factors than local habitat factors. In study landscapes containing semi-natural grasslands the relationship decelerated at high landscape species richness, suggesting that local species richness of butterflies in field boundaries is limited by habitat factors (demanding habitat specialists that occurred in semi-natural grasslands were absent in field margins). My results suggest that management options in field margins will affect mainly generalists, and species with good dispersal abilities, in landscapes with high arable field cover. Habitat specialists and species with poor dispersal abilities may benefit of management options if these are applied in the vicinity of source populations.

Structure and Bonding in Cyclic Isomers of B2AlHnm (n = 3−6, m = −2 to +1): A Comparative Study with B3Hnm, BAl2Hnm and Al3Hnm†

The structure, bonding and energetics of B2AlHnm (n = 3−6, m = −2 to +1) are compared with corresponding homocyclic boron, aluminum analogues and BAl2Hnm using density functional theory (DFT). Divalent to hexacoordinated boron and aluminum atoms are found in these species. The geometrical and bonding pattern in B2AlH4− is similar to that for B2SiH4. Species with lone pairs on the divalent boron and aluminum atoms are found to be minima on the potential energy surface of B2AlH32−. A dramatic structural diversity is observed in going from B3Hnm to B2AlHnm, BAl2Hnm and Al3Hnm and this is attributable to the preference of lower coordination on aluminum, higher coordination on boron and the higher multicenter bonding capability of boron. The most stable structures of B3H6+, B2AlH5 and BAl2H4− and the trihydrogen bridged structure of Al3H32− show an isostructural relationship, indicating the isolobal analogy between trivalent boron and divalent aluminum anion.
