Cyclic loss of open solar flux since 1868: the link to heliospheric current sheet tilt and implications for the Maunder Minimum

Open solar flux (OSF) variations can be described by the imbalance between source and loss terms. We use spacecraft and geomagnetic observations of OSF from 1868 to present and assume the OSF source, S, varies with the observed sunspot number, R. Computing the required fractional OSF loss, χ, reveals a clear solar cycle variation, in approximate phase with R. While peak R varies significantly from cycle to cycle, χ is surprisingly constant in both amplitude and waveform. Comparisons of χ with measures of heliospheric current sheet (HCS) orientation reveal a strong correlation. The cyclic nature of χ is exploited to reconstruct OSF back to the start of sunspot records in 1610. This agrees well with the available spacecraft, geomagnetic, and cosmogenic isotope observations. Assuming S is proportional to R yields near-zero OSF throughout the Maunder Minimum. However, χ becomes negative during periods of low R, particularly the most recent solar minimum, meaning OSF production is underestimated. This is related to continued coronal mass ejection (CME) activity, and therefore OSF production, throughout solar minimum, despite R falling to zero. Correcting S for this produces a better match to the recent solar minimum OSF observations. It also results in a cycling, nonzero OSF during the Maunder Minimum, in agreement with cosmogenic isotope observations. These results suggest that during the Maunder Minimum, HCS tilt cycled as over recent solar cycles, and the CME rate was roughly constant at the levels measured during the most recent two solar minima.

'Eden Cinema' by Marguerite Duras

Duras’s theatre work has been profoundly neglected by UK theatre academics and practitioners, and Eden Cinema has almost no performance history in Britain. My project asked three interconnected research questions: how developing the performance contributes to understanding Duras’s theatre and specifically Eden Cinema’s problems of performability; how multimedia performance emphasising mediated sound and the live body reconfigures memory, autobiography, storytelling, gender and racial identity; how to locate a performance style appropriate for Durasian narratives of displacement and death which reflect the discontinuous and mutable form of Duras’s ‘texte/film/théâtre’. Drawing on my research interests in gender, post-colonial hybridity and performed deconstruction, I focused my staging decisions on the discontinuities and ambivalences of the text. I addressed performability by avoiding the temptation to resolve the strange ellipses in the text and instead evoked the text’s imperfect and fragmented memories, and its uncertain spatial and temporal locations, by means of a fluid theatrical form. The mise-en-scène represented imagined and remembered spaces simultaneously, and co-existing historical moments. The performance style counterpointed live and mediated action and audio-visual forms. A complex through-composed soundscape, comprising voice-over, sound and music, became a key means for evoking overlapping temporalities, interconnected narratives and fragmented memories that were dispersed across the performance. The disempowerment of the mother figure and the silent indigenous servant in the text was demonstrated through their spatial centrality but physical stillness. The servant’s colonial subaltern identity was paralleled and linked with the mother’s disenfranchisement through their proxemic relationships. I elicited a performance style which evoked ‘characters’, whose being was deferred across different regimes of reality and who ‘haunted’ the stage rather than inhabited it. I developed the project further in the additional written outcomes and presentations, and the subsequent performance of Savannah Bay where problems of performability intensify until embodiment is almost erased except via voice.

I Fängelset : Regler och disciplinära åtgärder mot internerna på Falu fångvårdsanstalt under 1900-1905 och 1950-1955

Syftet med denna C-uppsats är att se vilka förändringar som ägde rum på Falu fångvårdsanstalt mellan två skilda perioder. Fokus ligger på de disciplinära åtgärder som vidtogs mot fångar som på något vis misskött sig på anstalten. Ena perioden är mellan 1900-1905 och den andra perioden är mellan 1950-1955. Under 1946 ägde en reformering av Svenska fångvården rum. Före detta år satt internerna isolerade i ensamceller och fick varken träffa eller språka med någon annan fånge under sin fängelsevistelse. Efter 1946 trädde reglementeringen i kraft där fångarna fick träffa varandra och samtala. Interner erhöll mer frihet än innan och den strikta ordning som funnits innan avtog så smått. Frågan som ställs i arbetet är vilka förändringar som går att finna före och efter 1946 års reglementering. Fången fick mer frihet efter detta år, men paradoxalt nog ökade skötsamhetsöverträdelserna efter 1946. De disciplinära åtgärderna fördubblades nästan i jämförelse med tidigare period. Det ökade förtroendet för internerna renderade i en högre grad av oordning på Falu fängelse och resultatet av undersökningen visar att det förekom fler förseelser 1950-1955 än 1900-1905. Källmaterialet till undersökningen består i huvudsak av förhörsprotokoll och straffjournaler från Falu fängelse för angiven tid, vilka har studerats på landsarkivet i Uppsala.

La formation d’une identité à l’intersection du genre, de l’ethnie et de la classe : Une analyse intersectionnelle de L’Amant de Marguerite Duras

Dans ce mémoire, nous nous sommes servies d’une méthode thématique pour faire une analyseintersectionnelle de L’Amant de Marguerite Duras. Le but était d’étudier la manière complexedont les différentes structures de domination interagissent l’une avec l’autre dans une sociétécoloniale. L’étude a été concentrée sur la recherche d’une identité personnelle effectuée par leprotagoniste féminin et nous avons voulu savoir comment cette recherche est influencée par lesstructures de genre, d’ethnie et de classe.Notre conclusion est que l’appartenance à la catégorie « blanche et pauvre » donne auprotagoniste un sentiment d’aliénation vis-à-vis de la communauté colonisatrice blanche. Cettealiénation l’aide à s’opposer à certaines normes, par exemple le manque de liberté sociale etsexuelle de la femme, en même temps que son comportement peut parfois être interprété commeune confirmation des rôles racistes existant dans la colonie. Néanmoins, nous voulons soulignerque c’est la façon dont l’amant chinois a été décrit qui est troublante, plutôt que lecomportement du protagoniste féminin.

La thématique de l’eau dans l’œuvre de Marguerite Duras

The aim of this thematic study is to examine how the water motif is used in Marguerite Duras’s literary work. The study shows that water has multiple functions in these texts: it is linked to major themes and creates an enigmatic atmosphere by its association with the unknown, the inexplicable and the unconscious. The strong presence of water in Duras’s texts is striking. References to the water element can be found in several titles throughout her career, from early works such as Un barrage contre le Pacifique (1950) to La mer écrite (1996), published just after her death. Almost all of her fiction take place near water – and the rain or the sound of waves serve as leitmotifs in specific novels. The water motif can play a metonymic as well as a metaphoric role in the texts and it sometimes takes on human or animalistic characteristics (Chapter 4). Several emblematic Durassian characters (e.g. the beggar-woman, Anne-Marie Stretter and Lol V. Stein) have a close relationship to water (Chapter 5). The water motif is linked to many major Durassian themes, and illustrates themes with positive connotations, for example, creation, fecundity, maternity, liberty and desire, as well as themes with negative connotations such as destruction and death (Chapter 6). A close reading of three novels, La vie tranquille (1944), L’après-midi de Monsieur Andesmas (1962) and La maladie de la mort (1982), shows that the realism of the first novel is replaced by intriguing evocations of the sea and the pond in the second text, motifs which resist straightforward interpretation. The enigmatic feeling persists in the last novel, in which the sea illustrates the overall sombre mood of the story (Chapter 7). Finally, the role of the water element in psychoanalytic theory is discussed (Chapter 8), and a parallel is drawn between the Jungian concept of the mother archetype and the water motif in Duras’s texts. The suggestion is made in this last chapter that water is used to illustrate an oriental influence (Taoist or Buddhist) of some of the female characters in Duras’s work.

"We Are All Homeless Wanderers". Transculturality and Modernism in the Works of Edith Södergran, Elias Canetti, Henry Parland and Marguerite Duras

This article investigates the notion of transculturality and applies it to four modernist authors of the 20th century: Edith Södergran, Elias Canetti, Henry Parland and Marguerite Duras. The concept of transculturality is used to reach a better – or at least different – understanding of the selected writers and their respective body of work.

As casas de Oscar Niemeyer - 1935-1955

A presente dissertação trata das casas projetadas pelo arquiteto Oscar Niemeyer, no período que compreende o início da sua carreira, em 1935, até a revisão autocrítica de 1955 – entre a Emergência e o final da Hegemonia da Arquitetura Moderna Brasileira. As 24 casas do período são apresentadas em ordem cronológica estudadas e analisadas individualmente, em paralelo ao conjunto de sua obra e considerando o contexto arquitetônico local e internacional. Contexto este especificamente representado pelos seus mestres confessos: Lucio Costa e Le Corbusier. As análises específicas de cada casa abordam: a sua motivação, o contexto histórico-cultural, os seus clientes, o lugar onde estão (ou estariam) e os seus aspectos compositivos, formais, funcionais e técnico-construtivos. O conjunto e contexto aparecem como suporte para a comparação, verificação de precedência, de influência, de renovação ou realimentação. Os resultados foram classificados, listados e quantificados afim de permitir futuros estudos sobre o tema. O trabalho procura também contribuir como meio de compilação, preservação e registro iconográfico desta parcela da obra de Niemeyer.

Government policy and private investment in Brazil (1955/82)

The questlon of the crowding-out of private !nvestment by public expenditure, public investment in particular , ln the Brazilian economy has been discussed more in ideological terrns than on empirical grounds. The present paper tries to avoid the limitation of previous studies by estlmatlng an equation for private investment whlch makes it possible to evaluate the effect of economic policies on prlvate investment. The private lnvestment equation was deduced modifylng the optimal flexible accelerator medel (OFAM) incorporating some channels through which public expendlture influences privateinvestment. The OFAM consists in adding adjustment costs to the neoclassical theory of investrnent. The investment fuction deduced is quite general and has the following explanatory variables: relative prices (user cost of capitaljimput prices ratios), real interest rates, real product, public expenditures and lagged private stock of capital. The model was estimated for private manufacturing industry data. The procedure adopted in estimating the model was to begin with a model as general as possible and apply restrictions to the model ' s parameters and test their statistical significance. A complete diagnostic testing was also made in order to test the stability of estirnated equations. This procedure avoids ' the shortcomings of estimating a model with a apriori restrictions on its parameters , which may lead to model misspecification. The main findings of the present study were: the increase in public expenditure, at least in the long run, has in general a positive expectation effect on private investment greater than its crowding-out effect on priva te investment owing to the simultaneous rise in interst rates; a change in economlc policy, such as that one of Geisel administration, may have an important effect on private lnvestment; and reI ative prices are relevant in determining the leveI of desired stock of capital and private investrnent.

A questão da qualidade do ensino nos planos oficiais de desenvolvimento da educação: 1955-1980

Este estudo trata da questão da qualidade do ensino, tal como ela se apresenta nos planos oficiais de desenvolvimento da educação, do período compreendido entre 1955 e 1980. O que se tentou buscar, durante todo o desenvolvimento do trabalho, foi o significado que a expressão melhoria da qualidade do ensino tomava no discurso oficial, procurando explicá-la do ponto de vista dos interesses das classes dominantes e, paralelamente, procurando perceber como as classes populares a entendiam no mesmo período. O estudo dos planos foi feito tendo presente que qualidade do ensino significa a prática pedagógica, desenvolvida nas escolas, capaz de dar aos alunos das classes populares a instrumentalidade necessária e a possibilidade de organização do conhecimento para que eles possam ter, efetivamente, participação no processo político do país, lutar pela superação de sua marginalização nas decisões políticas e buscar melhores condições de vida.
