Debt Portfolio Optimization at the Swedish National Debt Office: : A Monte Carlo Simulation Model / Skuldportföljsoptimering på Riksgälden: : En Monte Carlo-simuleringsmodell

Greberg, Felix January 2020 (has links)
It can be difficult for a sovereign debt manager to see the implications on expected costs and risk of a specific debt management strategy, a simulation model can therefore be a valuable tool. This study investigates how future economic data such as yield curves, foreign exchange rates and CPI can be simulated and how a portfolio optimization model can be used for a sovereign debt office that mainly uses financial derivatives to alter its strategy. The programming language R is used to develop a bespoke software for the Swedish National Debt Office, however, the method that is used can be useful for any debt manager. The model performs well when calculating risk implications of different strategies but debt managers that use this software to find optimal strategies must understand the model's limitations in calculating expected costs. The part of the code that simulates economic data is developed as a separate module and can thus be used for other studies, key parts of the code are available in the appendix of this paper. Foreign currency exposure is the factor that had the largest effect on both expected cost and risk, moreover, the model does not find any cost advantage of issuing inflation-protected debt. The opinions expressed in this thesis are the sole responsibility of the author and should not be interpreted as reflecting the views of the Swedish National Debt Office. / Det kan vara svårt för en statsskuldsförvaltare att se påverkan på förväntade kostnader och risk när en skuldförvaltningsstrategi väljs, en simuleringsmodell kan därför vara ett värdefullt verktyg. Den här studien undersöker hur framtida ekonomiska data som räntekurvor, växelkurser ock KPI kan simuleras och hur en portföljoptimeringsmodell kan användas av ett skuldkontor som främst använder finansiella derivat för att ändra sin strategi. Programmeringsspråket R används för att utveckla en specifik mjukvara åt Riksgälden, men metoden som används kan vara användbar för andra skuldförvaltare. Modellen fungerar väl när den beräknar risk i olika portföljer men skuldförvaltare som använder modellen för att hitta optimala strategier måste förstå modellens begränsningar i att beräkna förväntade kostnader. Delen av koden som simulerar ekonomiska data utvecklas som en separat modul och kan därför användas för andra studier, de viktigaste delarna av koden finns som en bilaga till den här rapporten. Valutaexponering är den faktor som hade störst påverkan på både förväntade kostnader och risk och modellen hittar ingen kostnadsfördel med att ge ut inflationsskyddade lån. Åsikterna som uttrycks i den här uppsatsen är författarens egna ansvar och ska inte tolkas som att de reflekterar Riksgäldens syn.

Předpovídání výnosové křivky na trhu s ropou pomocí neuronových sítí / Forecasting Term Structure of Crude Oil Markets Using Neural Networks

Malinská, Barbora January 2015 (has links)
This thesis enhances rare literature focusing on modeling and forecasting of term structure of crude oil markets. Using dynamic Nelson-Siegel model, crude oil term structure is decomposed to three latent factors, which are further forecasted using both parametric and dynamic neural network approaches. In-sample fit using Nelson-Siegel model brings encouraging results and proves its applicability on crude oil futures prices. Forecasts obtained by focused time-delay neural network are in general more accurate than other benchmark models. Moreover, forecast error is decreasing with increasing time to maturity.

City regeneration and the making of an urban experience : The Nelson Mandela bridge as sculpture

Stevens, Cheryl 20 October 2008 (has links)
“Nation building without city building is a senseless exercise” - Tomlinson et al (eds.) 2003: x. What is the nation in the 21st century and how is it represented in the urban built environment? This question underlies an anthropological investigation into the meanings of the Nelson Mandela Bridge project - a simulacrum for the making of a particular Johannesburg experience. The multi-million Rand fantasy of the urban imagineers showcases a post-apartheid inner city revival through the personification of a mayoral dream for a world-class city. The city’s textured socio-cultural and political-economic urbanity, its haphazard mining town origins and the aggressive apartheid urban politics, filter into its post-apartheid urban reconfiguration. The artful juggling of socio-cultural, political and economic elements launches the project as physical and symbolic entry-point into a new urban and historical era – a new urban frontier. The project’s technological innovation and slick excesses mirrors 21st century capitalist thinking – a packaging of local experiences into a marketable landscape commodified for moneyed consumption and participation. The privatisation of public space through modes of urban gentrification elicits elitist urban engagement in a partitioned and generic urban space. The latter conflicts with the project’s official branding as: “[being]‘for the good of all’. This research interrogates the adaptation of international best practices, the machinations of trans-nationalism in setting up urban experiences that contest individual constitutional and democratic rights. Contrasted here are the un-narrated voices of the city’s dark underbelly, the uncertainties of a marginalized majority struggling for a meagre existence in the inner-city in the face of the grand-scale urban regeneration project.

[en] NELSON RODRIGUES CONFESSIONS/FICTIONS / [pt] CONFISSÕES/FICÇÕES DE NELSON RODRIGUES

TIAGO LEITE COSTA 18 September 2007 (has links)
[pt] Este trabalho consiste numa análise das Confissões de Nelson Rodrigues, crônicas de costumes escritas na passagem da década de 1960 para 1970 e reeditadas recentemente em três coletâneas: O óbvio ululante, A cabra vadia e O reacionário. O propósito da dissertação é, a partir da leitura das crônicas, fazer emergir o personagem/narrador Nelson Rodrigues que trabalha na fronteira da ficção e da confissão. Narrador que cria outros personagens a partir das figuras públicas do Brasil daquele momento. Caberá verificar, então, como Nelson Rodrigues ficcionaliza a si próprio e aos outros protagonistas da década de 1960/70. / [en] This piece of work consists of an analysis of Nelson Rodrigues` Confessions, custom chronicles written in the passage from the 1960`s to the 1970`s and recently reedited in three compilations: O óbvio ululante, A cabra vadia, O reacionário. The purpose of this dissertation is to make emerge, from the reading of chronicles, the character/narrator, Nelson Rodrigues, who works on the thin line between fiction and confession. A narrator who creates other characters from the image of Brazilian public figures of the time. It will hence rest to verify how Nelson Rodrigues fictionalizes himself and other protagonists of the 1960`s and 70`s.

[en] NELSON RODRIGUES MEETS MANUEL BANDEIRA IN THE OBSESSIVE MEMORIES OF RUA ALEGRE / [pt] O ENCONTRO DE NELSON RODRIGUES E MANUEL BANDEIRA NAS LEMBRANÇAS OBSESSIVAS DA RUA ALEGRE

ANDRE COLSON SCORZA 17 August 2004 (has links)
[pt] Através do diálogo da obra rodrigueana com a de Manuel Bandeira, desafia-se a quebrar alguns preconceitos que povoam a recepção dos escritos de Nelson Rodrigues. O escritor releu a realidade de uma maneira bem própria, mas sem jamais deixar de mostrar a verdade ou, se preferirem dizer, A vida como ela é... A linha tênue entre o real e a ficção, o jornalismo e a literatura é o que dá toda a peculiaridade de sua criação; o real vira jornal, que é ficcionalizado virando crônicas, que viram contos, que viram teatro, que vira romance, que torna a ser teatro de novo. A temática sexual é central na obra rodrigueana, no entanto seu discurso é sempre em defesa do amor. Sendo a poesia de Bandeira uma busca apaixonada, a obra de Nelson Rodrigues também o é, ao representar a incessante busca do ser humano pela realização de seu erotismo; desse modo, conseguiu realizar na prosa tudo aquilo que Manuel realizara na poesia. / [en] Through the dialogue between the writings of Nelson Rodrigues and Manuel Bandeira`s poetry, an attempt is made to overcome some of the prejudice that marks the reception of Nelson Rodrigues`s work. Rodrigues reread reality on his very own way, but never failing to show the truth, or A vida como ela. (Life As It Is). The subtle line between the real and the fictional, journalism and literature, is the hallmark of his work; reality turns into news copy, which is ficcionalized into crônicas, which are made into short stories, which turn into plays, which turn into novels, which turn back into plays. The sexual motif is central in Rodrigues`s work, but his discourse is always a defense of love. If Bandeira`s poetry is a passionate search, so is Rodrigues`s writing, as it represents human beings` unceasing search for erotic gratification; in this way he achieved in prose everything that Manuel had done in poetry.

We aim to understand how a built text, called a second hand corpus, can apply linguistic clues that are typical of orality, and become a reality mimesis, without, however, reproduce it. Based on these concerns, we aim to answer: are there expressive oral marks at the play A falecida by Nelson Rodrigues? For that, we take, as parameters, the Sociolinguistic theoretical fundaments, the Conversation Analysis and the Speech Analysis. We assume that exist, in literature, some authors that are concerned about elaborate texts that aims to reproduce the naturalness of real dialogues. To achieve this spontaneity, however, these authors believe in a language with real syntactic-speech and morpholexicals features typical of orality. When we refer to the first features, we are concerned, at the tragedy A falecida, about the composition and the length of the sentences; the linguistic exchange among the participants of the interaction; the construction mode of the speech; the lack of time for planning and replanning the speeches, and other features. When we analyze the morpholexicals features, we are concerned about finding, at the written play, some marks recurrent in oral texts, like slangs, diminutive, hyperbolic constructions, phonetic transcriptions, and so on. Guided by theoretical concepts developed throughout the work, and submitting our conjectures to the analysis of the excerpts from the play A falecida, selected among so many others texts of the author, due his constant concern to portrait daily life, with its prose and its oral manifestations, we find, at the play, a lot of typical oral traces and observed that this kind of mark in a built text, when used conscious or unconsciously may help in the construction of a lot of implicit messages (or metamessages) / Este trabalho estuda as marcas de oralidade e a manifestação das metamensagens na tragédia carioca, A falecida, de Nelson Rodrigues, a fim de compreender se esse texto literário pode fornecer-nos marcas linguísticas capazes de funcionar como estratégias interacionais. Buscamos entender como um texto construído, um chamado corpus de segunda mão, consegue empregar indícios linguísticos típicos da oralidade a ponto de se tornar uma mimese da realidade, sem, contudo, ser uma reprodução exata desta. Com base nessas inquietações, propusemo-nos a responder: existem marcas orais expressivas na peça A falecida de Nelson Rodrigues? Para isso, tomamos, sobremaneira, como parâmetros, os fundamentos teóricos da Sociolinguística, da Análise da Conversação e da Análise do Discurso. Partimos do pressuposto de que existem, na literatura, alguns autores que se preocupam em elaborar textos que visem a reproduzir a naturalidade dos diálogos reais. Para conseguir essa espontaneidade, entretanto, esses autores apostam em uma linguagem com características sintático-discursivas e morfolexicais típicas da oralidade. Quando nos referimos às primeiras características, levamos em consideração, na obra A falecida, a composição e o tamanho das sentenças; a troca linguística entre os participantes da interação; o modo de construção do discurso, tanto pelo falante como pelo(s) ouvinte(s); a falta de tempo para o planejamento e o replanejamento das falas, entre outros fatores. Quando analisamos as características morfolexicais, preocupamo-nos em encontrar, na peça escrita, algumas marcas recorrentes em textos orais, tais como as gírias, os diminutivos, as construções hiperbólicas, as transcrições fonéticas, entre outros. Pautando-nos nos conceitos teóricos desenvolvidos ao longo do trabalho e submetendo nossas conjeturas à análise de trechos retirados da peça A falecida, selecionada em meio a tantas outras escritas pelo autor, devido à sua constante preocupação em retratar o cotidiano, com seu prosaísmo e suas manifestações orais, localizamos, na peça, muitos índices tipicamente orais e observamos que esse tipo de marca em um texto construído, quando usado de forma consciente ou quando empregado inconscientemente pode auxiliar na construção de muitas mensagens implícitas (ou metamensagens)

Besides that, it's a way to provide the members of a community different acts and behavior, considering the functioning and the established rules for the social group in which they are inserted. The objective of this work is to verify the present characteristics on the interacional process between the characters of the play Os sete gatinhos and the elements that compete for the establishment of relations on linguistic interaction, so present on spoken language, pointed out on a theater text. The present study begins from a small sample of international elements in the play and showing how the characters face the problems, for example, the use of pronouns, the "ready sentences" and the relations of knowledge that each one introduces, the diminutive and the intentionality that the use of this words can suggest in the context; the choice of a slang vocabulary and a lot of relations possible among the speakers that feel the need to preserve the face in front of these situations. The emotions, feelings and opinions present on the character's conversations reflect, in the text, marks of the speech / A linguagem tem como principal função transmitir informações entre os interlocutores. Além disso, é uma forma de propiciar aos membros de uma comunidade diferentes atos e comportamentos, levando-se em consideração os funcionamentos e regras estabelecidas pelo grupo social em que estão inseridos. O objetivo deste trabalho é verificar as características presentes no processo interacional entre as personagens da peça Os sete gatinhos e os elementos que concorrem para este estabelecimento, marcados em um texto teatral. O presente estudo parte de uma pequena amostra de elementos interacionais presentes na peça no intuito de demonstrar como as personagens se posicionam diante das estratégias no momento da conversação. Para isso, alguns elementos foram destacados, como por exemplo, o uso dos pronomes, as frases formulaicas (frases feitas) e as relações de conhecimento que cada uma apresenta, os diminutivos e a intencionalidade que o uso dessas palavras pode sugerir no contexto, a escolha de um vocábulo gírio e as muitas possibilidades de relações entre os interlocutores que sentem a necessidade de preservar a face diante de uma situação. As emoções, os sentimentos e as opiniões presentes nas falas das personagens refletem, no texto, marcas da oralidade

It is intended to characterize the scripted text from the uniqueness of the word to the three-dimensionality of the performance of the word theater, covering many arts in staging: the dialogue, song, dance, music, painting, lighting, etc. In the multiplicity of the scene, we highlight the character and his dialogic speech to achieve the reading of the state of the dramatic hybris, combining actor and spectator by catharsis of passions. Following the thesis Sabato Magaldi (1962), we set the comparison between the tragedy of Racine and the one of Nelson Rodrigues, showing the tragic axis, between reason and passion, the intrigue of the characters in an act of interpretive and analytical approach between the classical and the modern. The difference between both is recognized by the "way" the director leads passion by mediating the dialog of the characters and by mirroring the tragic model of Phèdre of Racine. The recognition achieved by means of dialog has provided a methodological support and reconceptualization of the word rectified on the border of literary language and the performing language of the modern tragic drama of Rodrigues / O objetivo desta dissertação é reconhecer o conceito de trágico e seu papel literário no roteiro teatral de Toda nudez será castigada (1965), do dramaturgo brasileiro Nelson Rodrigues. Pretende-se caracterizar o texto roteirizado a partir da unicidade da palavra à tridimensionalidade da performance da palavra teatral, abrangendo muitas artes na encenação: o diálogo, o canto, a dança, a música, a pintura, a iluminação, etc. Na multiplicidade da cena, destacamos a personagem e sua fala dialógica para alcançar a leitura do estado de hybris dramático, conjugando ator e espectador pela catarse das paixões. Seguindo a tese de Sábato Magaldi (1962), marcamos o confronto entre a tragédia de Racine e a de Nelson Rodrigues, evidenciando o eixo trágico, entre a razão e a paixão, na intriga cruzada das personagens, em ato de aproximação analítica e interpretativa entre o clássico e o moderno. A diferença entre ambos é reconhecida pelo modo como o diretor conduz a paixão pela mediação do diálogo dos personagens e pelo espelhamento aplicado do modelo trágico de Fedra de Racine. Sua resultante nos revelou o modo da transformação do papel do trágico na representação da arquipalavra cultural e social no teatro moderno de Nelson Rodrigues. O reconhecimento alcançado pela via da dialogicidade nos propiciou o suporte metodológico e a reconceituação da palavra reificada na fronteira da linguagem literária e da linguagem performática do teatro trágico moderno rodriguiano

Imagem, narrativa e subjetividade: an?lises pol?tico-afetivas em personagens dos filmes de Nelson Pereira dos Santos

In this way, a film analysis are developed based on the political-affective aspects of the characters of the films Rio, Zona Norte (1957) and Boca de Ouro (1962) by the director Nelson Pereira dos Santos . The political is treated in cinema from the perspective of Alain Badiou (2004), due to the fact that the characters manifest themselves politically in forms of resistance of dominations of their affections. With this assumption, it is aimed to reflect on how the characters Esp?rito and Boca de Ouro produce political-affective involvements in their daily lives. For that, a theoretical framework is composed especially by Jacques Ranci?re (2012), Sigfried Kracauer (2001) e Gilles Deleuze (1985). The analysis show that the political-affective of the characters is formed through fields of force produced by image-narrative interaction. In other words, in one way the image reveals forms of resistance, and the narrative reveals subjections, in another hand the narrative produces senses of resistance and the image reveals stabilization in forms of affective transformation of the characters. / Esta disserta??o prop?e-se a investigar as rela??es entre imagem, narrativa e o pol?tico por meio da subjetividade. Desse modo, s?o realizadas an?lises f?lmicas dos aspectos pol?tico-afetivos em personagens dos filmes Rio, Zona Norte (1957) e Boca de Ouro (1962), do diretor Nelson Pereira dos Santos. O pol?tico ? tratado no cinema na perspectiva de Alain Badiou (2004), para quem os personagens manifestam-se politicamente nas formas de resist?ncia ?s domina??es de seus afetos. Com esse pressuposto, procura-se refletir como os personagens Esp?rito e Boca de Ouro produzem envolvimentos pol?tico-afetivos em seus cotidianos. Para isso, mobiliza-se um quadro te?rico composto especialmente por Jacques Ranci?re (2012), Sigfried Kracauer (2001) e Gilles Deleuze (1985). As an?lises mostram que o pol?tico-afetivo dos personagens ? formado atrav?s de campos de for?as produzidos pela rela??o imagem-afeto-narrativa. Ou seja, ora a imagem revela formas de resist?ncia, e a narrativa, sujei??es, ora a narra??o produz sentidos de resist?ncia e a imagem revela estabiliza??es nas formas de transforma??o afetiva dos personagens.
