Abstract (sommario):

The SVI implied volatility model is a parametric model for stochastic implied volatility.The SVI is interesting because of the possibility to state explicit conditions on its parameters so that the model does not generate prices where static arbitrage opportunities can occur. Calibration of the SVI model to real market data requires non-linear optimization algorithms and can be quite time consuming. In recent years, methods to calibrate the SVI model that use its inherent structure to reduce the dimensions of the optimization problem have been invented in order to speed up the calibration. The ?first aim of this thesis is to justify the use of the model and the no static arbitrage conditions from a theoretic point of view. Important theorems by Kellerer and Lee and their proofs are discussed in detail and the conditions are carefully derived. The second aim is to implement the model so that it can be calibrated to real market implied volatility data. A calibration method is presented and the outcome of two numerical experiments validate it. The performance of the calibration method introduced in this thesis is measured in how big a fraction of the total market volume the method manages to ?t within the market spread. Tests show that the model manages to ?t most of the market volume inside the spread, even for options with short time to maturity. Further tests show that the model is capable to recalibrate an SVI parameter set that allows for static arbitrage opportunities into an SVI parameter set that does not.
SVI-modellen är en parametrisk modell för stokastisk implicit volatilitet. Modellen är intressant då det har visat sig möjligt att ställa upp villkor på dess parametrar så att priser den genererar för köp- och säljoptioner är fria från statiskt arbitrage. För att kalibrera SVI-modellen till marknadsdata krävs olinjär optimering, vilket i en implementering kan vara tidskrävande. På senare tid har kalibreringsmetoder som använder den inneboende strukturen i SVI-modellens parametrisering för att reducera dimensionen på optimeringen tagits fram. Den här uppsatsen har två syften. Det första är att berättiga SVI-modellen och villkoren för eliminering av statiskt arbitrage. Detta görs med en genomgång av den underliggande teorin. Viktiga satser av Kellerer och Lee presenteras, bevisas och diskuteras. Det andra syftet är att konstruera en kalibreringsmetod som möjliggör anpassning av SVI-modellen till marknadsdata och implementera denna. Utfallet av två numeriska experiment validerar kalibreringsmetoden. Kalibreringsmetodens prestanda mäts i hur stor del av marknadsvolymen som SVI-modellen lyckas anpassa inom spridningen av priser på marknaden. Tester visar på att kalibreringsmetoden lyckas anpassa den största delen av priserna innanför spridningen. Vidare tester visar att kalibreringsmetoden klarar av att omkalibrera SVI-modellen så att en parametermängd som till en början ger statisk arbitrage omvärderas till en parametermängd som är fri från statiskt arbitrage.

Abstract (sommario):

To understand and model the dynamics of the implied volatility smile is essential for trading, pricing and risk management portfolio. We suggest a linear Kalman filter for updating of the Stochastic Volatility Inspired (SVI) model of the volatility. From a risk management perspective we generate the 1-day ahead forecast of profit and loss (P\&L) of option portfolios. We compare the estimation of the implied volatility using the SVI model with the cubic polynomial model. We find that the SVI Kalman filter has outperformed the others.

Abstract (sommario):

Nondestructive evaluation techniques were employed to fully characterize three 2.3L camshafts tested in an engine simulator for an equivalent of 100,000 miles. Optical microscopy, acoustic microscopy (SAM), and profilometry were used to characterize wear and fatigue, crack depth, and surface roughness, respectively. Results show cracking to occur mainly in the opening ramp of the most abusively ground cam lobes. No clear evidence was found for subsurface cracking at depths as great as 200 mm from the lobe's surface. Profilometry results show no evidence of any major tribological effect due to the sliding friction of the follower. Fractography studies show a difference between fracture surfaces among the cracks examined; straight cracks exhibit features resembling fatigue propagation, while fracture surfaces from pitted cracks show a more brittle behavior. Small grinding cracks (approximately 300 mm in length) were found in the opening ramps of the most abusively ground lobes prior to testing. Knoop and Nanoindenter microhardness indicate a near-surface rehardening for the most abusively ground lobe (confirmed by metallography), and temper burn for the remaining lobes. X-ray residual stress results made in the opening ramp of the tested lobes show evidence of residual stress relaxation. X-ray line width data as a function of depth does not correlate with residual stress.

Abstract (sommario):

In this thesis will the question of how to construct implied volatility surfaces in a robust and arbitrage free way be investigated. To be able to know if the solutions are arbitrage free was an initial investigation about arbitrage in volatility surfaces made. From this investigation where two comprehensive theorems found. These theorems came from Roper in \cite{Roper2010}. Based on these where then two applicable arbitrage tests created. These tests came to be very important tools in the remaining thesis.The most reasonable classes of models for modeling the implied volatility surface where then investigated. It was concluded that the classes that seemed to have the best potential where the stochastic volatility models and the parametric representation models. The choice between these two classes where concluded to be based on a trade-off between simplicity and quality of the result. If it where possible to make the parametric representation models improve its result the best applicable choice would be that class. For the remaining thesis was it therefore decided to investigate this class. The parametric representation model that was chosen to be investigated where the SVI parametrization family since it seemed to have the most potential outside of its already strong foundation.The SVI parametrization family is diveded into 3 parametrizations, the raw SVI parametrization, the SSVI parametrization and the eSSVI parametrization. It was concluded that the raw SVI parametrization even though it gives very good market fits, was not robust enough to be chosen. This ment that the raw SVI parametrization would in most cases generate arbitrage in its surfaces. The SSVI model was concluded to be a very strong model compared to the raw SVI, since it was able to generate completely arbitrage free solutions with good enough results. The eSSVI is an extended parametrization of the SSVI with purpose to improve its short maturity results. It was concluded to give small improvements but with the trade of making the optimization procedure harder. It was therefore concluded that the SSVI parametrization might be the better application.To try to improve the results of the SSVI parametrization was a complementary procedure developed which got named the calibrated SSVI method. This method compared to the eSSVI parametrization would not change the parametrization but instead focusing on calibrating the initial fit that the SSVI generated. This method would heavily improve the initial fit of the SSVI surface but was less robust since it generated harder cases for the interpolation and extrapolation.
I det här examensarbetet undersöks frågan om hur man bör modellera implied volatilitetsytor på ett robust och arbitragefritt sätt. För att kunna veta om lösningarna är arbigtragefria börjades arbetet med en undersökning inom arbitrageområdet. De mest heltäckande resultatet som hittades var två theorem av Roper i \cite{Roper2010}. Baserat på dessa theorem kunde två applicerbara arbitragetester skapas som sedan kom att bli en av hörnstenarna i detta arbete. Genom att undersöka de modellklasser som verkade vara de bästa inom området valdes den parametriseringsbeskrivande modellklassen. I denna klass valdes sedan SVI parametriseringsfamiljen för vidare undersökning eftersom det verkade vara den familj av modeller som hade störst potential att uppnå jämnvikt mellan enkel applikation samt bra resultat. För den klassiska SVI modellen i SVI familjen drogs slutsatsen att modellen inte var tillräcklig för att kunna rekommenderas. Detta berodde på att SVI modellen i princip alltid genererade lösningar med arbitrage i. SVI modellen genererar dock väldigt bra lösningar mot marknadsdatan enskilt och kan därför vara ett bra alternativ om man bara ska modellera ett implied volatilitetssmil. SSVI modellen ansågs däremot vara ett väldigt bra alternativ. SSVI modellen genererar komplett aribragefria lösningar men har samtidigt rimligt bra marknadspassning. För att försöka förbättra resultaten från SSVI modellen, var en kompleterande metod kallad den kalibrerade SSVI metoden skapad. Denna metod kom att förbättra marknadspassningen som SSVI modellen genererade men som resultat kom robustheten att sjunka, då interpoleringen och extrapoleringen blev svårare att genomföra arbitragefritt.

Abstract (sommario):

Syftet med denna studie är att undersöka vad som händer när ett läromedel i kursen Svenska 1 ändras och anpassas till kursen Svenska som andraspråk 1. I undersökningen har granskats huruvida innehållet i de båda läromedlens kapitel om språksociologi motsvarar intentionerna i det centrala innehållet. Dessutom har de innehållsliga och formmässiga förändringar SVE-boken genomgått för att bli SVA studerats. Genom närläsning av de bägge kapitlen har innehåll och språklig form granskats, och fynden har kategoriserats och analyserats. De viktigaste resultaten är att stoffet i läromedlen motsvarar det centrala innehållet relativt väl, men att det finns en avsevärd skillnad i innehållet mellan de båda bokversionerna. Språket har när SVE blivit SVA vid enstaka tillfällen förenklats, vilket gett innehållsliga skillnader, men har i övrigt inte ändrats i någon väsentlig grad.

Abstract (sommario):

Depression is a significant public health problem for young adults of college age, and negative life events exacerbate risk. Not all individuals who experience negative life events, however, report depressive symptoms, perhaps owing to protective characteristics. We examined one such characteristic, trait hope, a goal-oriented construct, as a potential moderator of the association between negative life events and depressive symptoms in an ethnically diverse sample of 386 college students. In support of our hypotheses, negative life events were significantly associated with greater levels of depressive symptoms, and higher levels of hope attenuated this relationship, such that those with greater hope reported fewer depressive symptoms related to potentially traumatic events. The moderating effect of hope did not differ across ethnic groups. Our findings have implications for managing the sequelae of negative life events, including depression. Cognitive–behavioural interventions tailored to help young adults identify and attain important life goals might help to overcome psychopathology associated with life stress.

Abstract (sommario):

I dagens läroplan för grundskolan (Lgr 11) finns syftesbeskrivningar för de naturOrienterande (NO) ämnena som säger att eleverna ska utveckla kunskaper och redskap för att formulera och granska information och andras argument samt ta ställning i frågor som rör ämnen med naturvetenskapligt innehåll. Detta är formuleringar som speglar det man i dag anser att NO-undervisningen ska ge de elever som går ut grundskolan. I det här arbetet har elever i slutet av högstadiet fått argumentera kring användandet av genmodifierade grödor (Genetically Modified Organism, GMO). Detta är ett exempel på så kallade Samhällsfrågor med Naturvetenskapligt Innehåll (SNI) och den här typen av samhällsfrågor har lyfts fram som ett sätt att arbeta med de formuleringar som nu finns i läroplanen. Syftet med den här studien är att undersöka högstadieelevers användning av argument i en naturvetenskapligt grundad diskussion och hur användningen av SNI i undervisningen kan hjälpa elever att utveckla sin argumentationsteknik och sitt intresse för naturvetenskap. Elevernas argumentation kring frågan om GMO har analyserats utifrån en analysmodell som är utvecklad för granskning av argumentation om SNI. Den här studien har funnit att användandet av SNI fungerar väl för att testa delar av läroplanens kunskapskrav men att det kräver noga förberedelser och att övningarna är väl uppbyggda.

Abstract (sommario):

The design and implementation of a synthesizable model of the Serial Communication Interface and Synchronous Serial Interface, which constitutes the Port C of Motorola DSP56002 is presented in this report. They serves as a full duplex serial interface to other DSPs, processors, codecs, digital-to-analog and analog-to-digital converters and other transducers. The SCI block is able to handle a data rate of 5Mbps in Synchronous mode and 625Kbps in asynchronous mode for a 40MHz clock. It supports five word formats including a multidrop mode for multiprocessor systems. SSI provides a data rate of 10Mbps for the same 40 MHz clock. The design includes a programmable on-chip or external baud rate generator/interrupt timer for the SCI and a clock generator and frame Sync generator for the SSI.

The thesis focus on arriving at a full functional description of individual blocks included with Port C from the data sheets and product users manual. From this operational description a behavioural model was developed. The structure and implementation is based on the Motorola DSP56002 with additional support for a variable data-width. The model is written completely in behavioural VHDL with a top-down approach and the model was verified and validated.

Testo completo

Abstract (sommario):

L'intégration monolithique des composants de puissance se justifie par la réduction des coûts de fabrication et par l'amélioration des performances des dispositifs électroniques de puissance en termes de fonctionnalités et de fiabilité. Pour l'heure, ce domaine de l'électronique de puissance ne concerne que les applications faible et moyenne puissance. En effet l'isolation entre les différentes fonctions électriques demeure l'aspect le plus pénalisant en ce qui concerne la fiabilité de ce type de composant. Dans cette étude nous nous proposons de caractériser deux types d'isolation. Notre travail porte tout d'abord sur l'interaction puissance-commande entre un nouveau composant de puissance à grille isolée bidirectionnel en tension, le MBS (Mos Bidirectional Switch), et sa commande intégrée. Il s'agit alors de montrer les limites de l'isolation par jonction PN lorsque le niveau de tension atteint quelques centaines de volts (600 V). Des modèles sont développés pour permettre de comprendre les phénomènes de génération des perturbations durant les différents régimes de fonctionnement de l'interrupteur de puissance. Dans un second temps, nous nous intéressons à l'étude des interactions entre composants de puissance au travers de la caractérisation de l'isolation diélectrique des composants sur SOI (Silicon On Insulator). Nous déterminons alors le couplage capacitif qui existe entre deux caissons d'isolation et qui peut conduire à un déclenchement parasite des composants réalisés à l'intérieur. Enfin l'ensemble de notre réflexion sur les performances des deux types d'isolation est synthétisée dans un bilan comparatif, dont l'objectif final est de mieux cerner les domaines d'applications de ces deux choix technologiques.

Abstract (sommario):

This thesis focuses on the translation of six picture books that challenge and subvert – each one in its peculiar way – typical stereotypes found in Children’s Literature. I think that stereotyping is an all-important theme in picture books because these books are the ones that will introduce children to literature and young readers have the right to find in it every kind of model. Showing children a variety of characters that reflects the multiple forms of reality will allow them to choose which kind of person to be. In my opinion, this freedom is much needed especially here, in Italy, in this moment of history. This work also studies the stereotypes that have appeared – and are still present, to some extent – in Children’s Literature, the ways in which they are dangerous for young readers, and how they have changed over time. I centered my research on three major themes that have been subject to stereotyping: race, disability and gender. I searched for the right books to translate paying attention not only to the themes they focused on but also to how they dealt with such themes, the tone of each picture book and, obviously, its quality. The selection resulting from my research reflects a diverse world and a celebration of difference. Before actually translating them, I engaged in a deep analysis of their structures, themes and meanings, so that I would be able to enter the ‘world’ of the book and to understand its ‘secrets’ better. This analysis proved to be fundamental during the translation phase and allowed me to make conscious translation choices that I have explored in the part dedicated to the commentary of the translation.

This book contains the design for a vacation house. This house is situated on the south facing slope of Lone Mountain in Gallatin County, Montana and receives heavy snowfall each year. This project was primarily explored through model making and focused on the relationship of different materials to one another and the spaces those materials can create. The contrast between concrete and wood best shows the dynamic use of materials in the house. The final design of the house evolved through the way different elements and materials responded and interacted with one another.

Abstract (sommario):

Skönlitteratur ska inkluderas i alla SVA-kurser (1, 2, 3) på gymnasiet enligt Gy11. Syftet med denna uppsats är att undersöka vilken roll SVA-lärarstudenter tycker att skönlitteraturen bör ha i SVA-undervisningen. Uppsatsen ämnar svara på vilken funktion studenterna tycker att skönlitteraturen fyller i SVA-undervisningen, hur de ser på skönlitteraturens plats i styrdokumenten och även hur SVA-lärarutbildningen har förberett dem för framtida skönlitterär undervisning i SVA. Metoden för studien är kvalitativ intervju, dels genom fokusgruppintervju och dels genom uppföljande individuella intervjuer. Informanterna är sex SVA-lärarstudenter på ämneslärarprogrammet på Uppsala universitet. Resultatet visade att informanterna menar att skönlitteratur kan bidra till språkutveckling, identitetsskapande och omvärldskunskap och därav bör ha en given plats i SVA-undervisningen. Däremot upplever informanterna sig mindre väl förberedda inför att undervisa om skönlitteratur i SVA, då deras egen SVA-lärarutbildningen innehåller för lite skönlitteraturundervisning och för liten praktisk anknytning.

Many large coal mining operations in Australia rely heavily on the rail network to transport coal from mines to coal terminals at ports for shipment. Over the last few years, due to the fast growing demand, the coal rail network is becoming one of the worst industrial bottlenecks in Australia. As a result, this provides great incentives for pursuing better optimisation and control strategies for the operation of the whole rail transportation system under network and terminal capacity constraints. This PhD research aims to achieve a significant efficiency improvement in a coal rail network on the basis of the development of standard modelling approaches and generic solution techniques. Generally, the train scheduling problem can be modelled as a Blocking Parallel- Machine Job-Shop Scheduling (BPMJSS) problem. In a BPMJSS model for train scheduling, trains and sections respectively are synonymous with jobs and machines and an operation is regarded as the movement/traversal of a train across a section. To begin, an improved shifting bottleneck procedure algorithm combined with metaheuristics has been developed to efficiently solve the Parallel-Machine Job- Shop Scheduling (PMJSS) problems without the blocking conditions. Due to the lack of buffer space, the real-life train scheduling should consider blocking or hold-while-wait constraints, which means that a track section cannot release and must hold a train until the next section on the routing becomes available. As a consequence, the problem has been considered as BPMJSS with the blocking conditions. To develop efficient solution techniques for BPMJSS, extensive studies on the nonclassical scheduling problems regarding the various buffer conditions (i.e. blocking, no-wait, limited-buffer, unlimited-buffer and combined-buffer) have been done. In this procedure, an alternative graph as an extension of the classical disjunctive graph is developed and specially designed for the non-classical scheduling problems such as the blocking flow-shop scheduling (BFSS), no-wait flow-shop scheduling (NWFSS), and blocking job-shop scheduling (BJSS) problems. By exploring the blocking characteristics based on the alternative graph, a new algorithm called the topological-sequence algorithm is developed for solving the non-classical scheduling problems. To indicate the preeminence of the proposed algorithm, we compare it with two known algorithms (i.e. Recursive Procedure and Directed Graph) in the literature. Moreover, we define a new type of non-classical scheduling problem, called combined-buffer flow-shop scheduling (CBFSS), which covers four extreme cases: the classical FSS (FSS) with infinite buffer, the blocking FSS (BFSS) with no buffer, the no-wait FSS (NWFSS) and the limited-buffer FSS (LBFSS). After exploring the structural properties of CBFSS, we propose an innovative constructive algorithm named the LK algorithm to construct the feasible CBFSS schedule. Detailed numerical illustrations for the various cases are presented and analysed. By adjusting only the attributes in the data input, the proposed LK algorithm is generic and enables the construction of the feasible schedules for many types of non-classical scheduling problems with different buffer constraints. Inspired by the shifting bottleneck procedure algorithm for PMJSS and characteristic analysis based on the alternative graph for non-classical scheduling problems, a new constructive algorithm called the Feasibility Satisfaction Procedure (FSP) is proposed to obtain the feasible BPMJSS solution. A real-world train scheduling case is used for illustrating and comparing the PMJSS and BPMJSS models. Some real-life applications including considering the train length, upgrading the track sections, accelerating a tardy train and changing the bottleneck sections are discussed. Furthermore, the BPMJSS model is generalised to be a No-Wait Blocking Parallel- Machine Job-Shop Scheduling (NWBPMJSS) problem for scheduling the trains with priorities, in which prioritised trains such as express passenger trains are considered simultaneously with non-prioritised trains such as freight trains. In this case, no-wait conditions, which are more restrictive constraints than blocking constraints, arise when considering the prioritised trains that should traverse continuously without any interruption or any unplanned pauses because of the high cost of waiting during travel. In comparison, non-prioritised trains are allowed to enter the next section immediately if possible or to remain in a section until the next section on the routing becomes available. Based on the FSP algorithm, a more generic algorithm called the SE algorithm is developed to solve a class of train scheduling problems in terms of different conditions in train scheduling environments. To construct the feasible train schedule, the proposed SE algorithm consists of many individual modules including the feasibility-satisfaction procedure, time-determination procedure, tune-up procedure and conflict-resolve procedure algorithms. To find a good train schedule, a two-stage hybrid heuristic algorithm called the SE-BIH algorithm is developed by combining the constructive heuristic (i.e. the SE algorithm) and the local-search heuristic (i.e. the Best-Insertion- Heuristic algorithm). To optimise the train schedule, a three-stage algorithm called the SE-BIH-TS algorithm is developed by combining the tabu search (TS) metaheuristic with the SE-BIH algorithm. Finally, a case study is performed for a complex real-world coal rail network under network and terminal capacity constraints. The computational results validate that the proposed methodology would be very promising because it can be applied as a fundamental tool for modelling and solving many real-world scheduling problems.

Abstract (sommario):

Streamciphers are common cryptographic algorithms used to protect the confidentiality of frame-based communications like mobile phone conversations and Internet traffic. Streamciphers are ideal cryptographic algorithms to encrypt these types of traffic as they have the potential to encrypt them quickly and securely, and have low error propagation. The main objective of this thesis is to determine whether structural features of keystream generators affect the security provided by stream ciphers.These structural features pertain to the state-update and output functions used in keystream generators. Using linear sequences as keystream to encrypt messages is known to be insecure. Modern keystream generators use nonlinear sequences as keystream.The nonlinearity can be introduced through a keystream generator's state-update function, output function, or both. The first contribution of this thesis relates to nonlinear sequences produced by the well-known Trivium stream cipher. Trivium is one of the stream ciphers selected in a final portfolio resulting from a multi-year project in Europe called the ecrypt project. Trivium's structural simplicity makes it a popular cipher to cryptanalyse, but to date, there are no attacks in the public literature which are faster than exhaustive keysearch. Algebraic analyses are performed on the Trivium stream cipher, which uses a nonlinear state-update and linear output function to produce keystream. Two algebraic investigations are performed: an examination of the sliding property in the initialisation process and algebraic analyses of Trivium-like streamciphers using a combination of the algebraic techniques previously applied separately by Berbain et al. and Raddum. For certain iterations of Trivium's state-update function, we examine the sets of slid pairs, looking particularly to form chains of slid pairs. No chains exist for a small number of iterations.This has implications for the period of keystreams produced by Trivium. Secondly, using our combination of the methods of Berbain et al. and Raddum, we analysed Trivium-like ciphers and improved on previous on previous analysis with regards to forming systems of equations on these ciphers. Using these new systems of equations, we were able to successfully recover the initial state of Bivium-A.The attack complexity for Bivium-B and Trivium were, however, worse than exhaustive keysearch. We also show that the selection of stages which are used as input to the output function and the size of registers which are used in the construction of the system of equations affect the success of the attack. The second contribution of this thesis is the examination of state convergence. State convergence is an undesirable characteristic in keystream generators for stream ciphers, as it implies that the effective session key size of the stream cipher is smaller than the designers intended. We identify methods which can be used to detect state convergence. As a case study, theMixer streamcipher, which uses nonlinear state-update and output functions to produce keystream, is analysed. Mixer is found to suffer from state convergence as the state-update function used in its initialisation process is not one-to-one. A discussion of several other streamciphers which are known to suffer from state convergence is given. From our analysis of these stream ciphers, three mechanisms which can cause state convergence are identified.The effect state convergence can have on stream cipher cryptanalysis is examined. We show that state convergence can have a positive effect if the goal of the attacker is to recover the initial state of the keystream generator. The third contribution of this thesis is the examination of the distributions of bit patterns in the sequences produced by nonlinear filter generators (NLFGs) and linearly filtered nonlinear feedback shift registers. We show that the selection of stages used as input to a keystream generator's output function can affect the distribution of bit patterns in sequences produced by these keystreamgenerators, and that the effect differs for nonlinear filter generators and linearly filtered nonlinear feedback shift registers. In the case of NLFGs, the keystream sequences produced when the output functions take inputs from consecutive register stages are less uniform than sequences produced by NLFGs whose output functions take inputs from unevenly spaced register stages. The opposite is true for keystream sequences produced by linearly filtered nonlinear feedback shift registers.

Abstract (sommario):

Den första juli 2007 kommer en ny transporträttskonvention att träda i kraft. Konventionen förbereds av FN-organet UNCITRAL och avser behandla internationella transporter, där hela eller största delen av transporten sker till sjöss. De multimodala transporterna – alltså de där mer än ett transportsätt används i en transportkedja – ökar stadigt i omfattning och behovet av en harmonisering av internationella transporter är stort. Eftersom UNCITRAL:s konvention ämnar omfatta även till internationella sjötransporter anslutande landtransporter är ett av uppsatsens syften att undersöka hur omfattande denna multimodalitet är. En annat syfte med uppsatsen är att utreda huruvida multimodala transporter kan anses utgöra ett transportsätt sui generis. I uppsatsen kommer en fiktiv transport från New York till Oslo, via Rotterdam och Göteborg, att företas och analyseras. Inom ramen för exempeltransporten presenteras de regler som är aktuella om transporten företas idag och de regler som blir aktuella på transporten när UNCITRAL:s konvention trätt ikraft.

Abstract (sommario):

Our governing documents give teachers guidelines as to how to carry out their task in the classroom. To guide a learner requires knowledge, not only about the policy of our governing documents but also skills to see the connection between the teacher's task and its practical implementation. By studying learners' experiences of teaching contexts, I have been able to evaluate how the teaching methods live up to the intentions of the national governing documents in Sweden. My study is based partly on a survey that I completed and partly on the theory of Dialogicity. Here I saw clear connections between my informants' experiences of verbal exercises in the teaching and the theoretical background I have chosen for my study, Dialogicity. I have presented and analyzed the verbal exercises in four differentiated contexts. My results show how the concepts surrounding Dialogicity can be interpreted and put into practice in our educational work. The findings of my study argue for a pedagogy based on a holistic approach to learning. The results of this study suggest a need for a deeper consideration of the relationship between our theories, our steering documents and our actual work in the classroom.

Syftet med den här uppsatsen är att ta reda på och beskriva på vilket sätt och hur medvetet undervisande lärare arbetar med interaktionen lärare/– elev och interaktionen elever emellan vid val av klassrumsaktiviteter, samt hur dessa val ter sig i praktiken. Metoden som används är en kvalitativ intervju med fyra Sfi-lärare som arbetar med olika kurser på en och samma skola samt klassrumsobservationer av lärarnas undervisning i deras egna grupper. Resultatet av studien visar att lärarna har en intention att arbeta utifrån interaktionens roll i andraspråkinlärningen och andraspråkundervisningen och använder sig av arbetssätt som främjar interaktionen mellan lärare och elever men även elever emellan. Flera av de aktiviteter som lärarna använder i sin undervisning, särskilt de som utförs i smågrupper, bidrar till en kreativ språkanvändning och en naturlig kommunikation trots att de sker i en institutionell samtalsmiljö. Slutsatsen som dras är att interaktionen inte syns i de flesta lärarnas lektionsplanering. Interaktionen visar sig dock tydligt under klassrumsarbetet. Lärarnas sätt att interagera med eleverna utifrån frågornas slag, IRF-sekvenser och lärarnas språkanpassning varierar beroende på deltagarnas nivå. Även lärarnas val av klassrumsaktiviteter förändras. Det förekommer fler aktiviteter mellan deltagare i grupper som är på mer avancerad nivå än i grupper på en lägre nivå.

Quérini, Nicolas. "De la connaissance de soi au devenir soi : Platon-Nietzsche". Thesis, Strasbourg, 2020. http://www.theses.fr/2020STRAC019.

Testo completo

Abstract (sommario):

Tout en critiquant la morale occidentale ancrée selon lui dans la sentence delphique « Connais-toi toi-même», Nietzsche développe pour sa part un impératif qui est, selon nous, le prolongement naturel et nécessaire d'un « Connais-toi toi-même » bien compris. C'est donc à partir de l'injonction à devenir soi qu’il opère la critique de la morale issue elle-même de l’invitation à la connaissance de soi. Il ne s’agit toutefois pas de rabattre l’éthique nietzschéenne du devenir-soi sur la façon dont on peut comprendre ce syntagme chez Platon. L’usage qu’en propose Nietzsche est bien, selon nous, tout à fait singulier. On ne saurait nier, cependant, qu’il n’est pas non plus sorti du néant et que Nietzsche tire d’abord des enseignements de Pindare, réinterprétant lui-même la sentence delphique, lorsqu’il écrit « Deviens tel que tu as appris à te connaître ». Nous pensons donc que Nietzsche récupère la formule de Pindare par delà Platon pour critiquer ce dernier et, à travers lui, toute la philosophie qui a fait de la connaissance de soi le départ de l'éthique. Mais nous voudrions donc également essayer de rendre justice à Platon, puisque sa philosophie libère en réalité la possibilité de devenir ce que l’on est
While criticizing the Western morality anchored, according to him, in the Delphic sentence “Know yourself”, Nietzsche develops for his part an imperative which is, in our opinion, the natural and necessary extension of the self-knowledge. It is, therefore, from the injunction to become oneself that he operates the criticism of morality itself resulting from the invitation to self-knowledge. It is not, however, a question of reducing the Nietzsche an ethics of becoming-self to the way in which one can understand this syntagm in Plato. The use that Nietzsche proposes of it is indeed, in our opinion, quite singular. It cannot be denied, however, that it also did not come out of nothing and that Nietzsche first draws lessons from Pindar, who reinterprets himself the Delphic sentence, when he writes “Becomeas you have learned to know youself”. We therefore think that Nietzsche recovers Pindar’s formula beyond Plato, to criticize the latter and, through him, the whole philosophy which made self knowledge the departure of ethics. But we would therefore also try to do justice to Plato, since his philosophy actually frees the possibility of becoming ourself

Abstract (sommario):

Cette thèse retrace les étapes de la création d’un dispositif projectif permettant d’explorer le soi-archaïque d’un sujet adulte. Son élaboration est le fruit de plusieurs recherches antérieures auprès de diverses populations : sujets adultes ne présentant pas de pathologie reconnue, jeunes adultes psychotiques et/ou états-limites, sujets adultes paraplégiques. Le dispositif créé pour ces recherches a évolué pour devenir un outil d’exploration et de médiation utilisé depuis plusieurs années dans le cadre de mes prises en charges thérapeutiques, auprès de patients souffrants majoritairement de troubles narcissiques identitaires.Des photographies de l’espace, pour la plupart prises par le CNRS ou la NASA avec différents télescopes sont utilisées comme support projectif. Avec ces photographies, l’impact esthétique est indéniable. « Que représente pour vous l’univers ? » : L'utilisation de photographies de divers objets célestes comme support projectif pour répondre à une question latente sur la subjectivité mobilise la pensée en images et vient questionner le sentiment de soi actuel et archaïque. Ces photographies offrent une figuration de vécus originaires, métaphores cosmiques déjà remarquées dans la littérature psychanalytique (Anzieu et les signifiants formels, Aulagnier et le trou noir de la psyché…), elles favorisent une mise en scène imagée des interactions précoces.Le dispositif de l’EPSA est un « attracteur » sollicitant la projection d’un "incréé", d’une expérience en souffrance de symbolisation. La malléabilité de l’EPSA permet au sujet de la mettre en forme, raconter l’histoire de ce qu’il ne connait pas de lui et qui le hante. Le sujet projette dans l’EPSA une ambiance psychique, trace d’un soi-émergent dans un fonctionnement parfois en souffrance, où apparaissent des « processus » de transformation.L’EPSA permet d’explorer les capacités réflexives du sujet : Capacités du sujet à élaborer ou non un conflit esthétique, la gestion et l’expression de ce conflit. Capacités à « raisonner » affectivement, à être en contact avec ses émotions, à les éprouver. Se sentir, se voir, « dire » ses émotions. (Trois « degrés » de symbolisation).La maturité du soi archaïque et son expression (maturité affective du sentiment de soi) peut se définir ainsi : la tolérance et l’acceptation des affects, émotions, sentiments… provoqués par les conflits à se penser sujet. La capacité à ne pas être « débordé » affectivement sans trop d’évitement et d’inhibition. L’élaboration psychique et verbale de ces conflits (le partage et la communication avec autrui).L’EPSA permet ainsi d’observer chez l’adulte des troubles liés aux premiers stades de développement : le traitement de l’affect, les interactions précoces, les troubles dus à des déficiences dans l’accordage… L’EPSA est un outil d’exploration de certains processus importants dans la construction de la subjectivité, et permet d’affiner notre regard clinique concernant les troubles identitaires narcissiques, état-limites, pathologies de la dépendance…La passation de l’EPSA, en proposant au sujet de rapporter ses impressions, favorise un travail de mise en forme et de mise en mots. C’est un espace créatif, de trouvé/créé. Un dispositif symbolisant et de partage et rencontre. Il est un objeu, un support thérapeutique. Finalement, l’EPSA est un miroir de soi, et aussi un outil de « transformation », de symbolisation
This thesis traces the steps of creating a projective device for exploring the self-archaic of an adult subject. Its development is the result of several former studies from various groups: adult subjects with no pathology recognized, young psychotic adults and/or borderlines, and adult paraplegic subjects. The device created for this research has evolved into an exploration and mediation tool used for many years as part of my therapeutic group of patients, mostly suffering from identity narcissistic disorders.Photographs of space, mostly taken by the CNRS or NASA with different telescopes, are used a carrier. With these photographs, the visual impact is undeniable. "What does the Universe mean to you?": The use of photographs of various celestial objects as projective medium to respond to a latent question about subjectivity, mobilizes thinking in images and comes to question the sense of self, archaic and current. The photographs offer a representation of native experiences, cosmic metaphors already presented in the psychoanalytic literature (Anzieu and formal signifiers, Aulagnier and the black hole of the psyche... These favor an imaged scene of early interactions.The EPSA device is an "attractor" seeking the projection of an "uncreated" image, an experience in default of symbolization. The EPSA malleability allows the patient to put into shape the uncreated, to tell the story of what he does not know of himself and that haunts him. The subject projects into the EPSA a psychic atmosphere, a trace of an emerging self with an operation that is sometimes problematic, in which appears "processes" of transformation.EPSA explores the reflexive capacities of the subject: the subject ability to be able to develop or not an aesthetic conflict, management and expression of conflict. It is also explores the ability to "reason" emotionally, to be in touch with his emotions, to experience them, to feel oneself, to see oneself, and "to express" his emotions (Three "degrees" of symbolization).The maturity of the archaic self and its expression (emotional maturity of the sense of self) can be defined as the tolerance and acceptance of affects, emotions, and feelings... caused by conflicts to think about oneself. In this way, the subject avoids being "overwhelmed" emotionally and inhibition. The mental and verbal elaboration of conflicts provides for sharing and communication with others.EPSA allows us to observe in adults the relationship in the early stages of development disorders: treatment of affect, early interactions, and disorders due to deficiencies in the tuning... EPSA is an exploration of an important tool in the construction of subjectivity processes, and refines our clinical look on narcissistic identity disorders, borderline condition, and disease of addiction...The EPSA device, which proposes the patient to imagine his impressions, enables the patient to put words to his thoughts. It is a creative space in which we found and create. A symbolizing device which encourages sharing and meeting. It is an "objeu", a therapeutic carrier. Finally, EPSA is a mirror of oneself, and also a tool of "transformation" of symbolization

I studien undersöks svensklärares val av undervisningsmetoder och innehåll vid arbetet med skönlitteratur i kurserna Svenska 1–3, SVA 3 och SFI kurs D. Studien ämnade att svara på hur lärarna motiverar didaktiska val utifrån skolans uppdrag, vilka val lärarna gör kopplat till elevernas måluppfyllelse och utbildningsform samt hur läraren implementerar elevinflytande och medbestämmande vid skönlitterära inslag i svenskundervisningen. För att besvara frågeställningarna genomfördes tretton tematiserade kvalitativa intervjuer med verksamma svensklärare och svaren har sedan diskuterats ur ett sociokulturellt perspektiv med fokus på den proximala utvecklingszonen. Studiens resultat visar att styrdokumenten anses vara svårtolkade och frasen skönlitteratur och andra typer av texter har tolkats på flertalet olika sätt. Det resultaten visar är att eleverna inte ges likvärdig tillgång till skönlitterära texter i svenskundervisningen och att det främst beror på lärarens tolkning av styrdokumenten eller på grund av att läraren anser att eleverna, som främst företräds av studerande på yrkesprogram, anses vara för lässvaga. De övergripande resultaten visar att elever på yrkesförberedande program möts av för låga förväntningar i undervisningen i kurser som avser Svenska vilket resulterar i att en av fyra yrkeselever riskerar att inte nå måluppfyllelse i kursen Svenska 1 vilket går i linje med resultat från Skolverks kvalitetsgranskningar.

Abstract (sommario):

In this Ph.D. dissertation we deal with the issue of the regularity and the estimation of probability laws for diffusions with non-globally smooth coefficients, with particular focus on financial models. The analysis of probability laws for the solutions of Stochastic Differential Equations (SDEs) driven by the Brownian motion is among the main applications of the Malliavin calculus on the Wiener space: typical issues involve the existence and smoothness of a density, and the study of the asymptotic behaviour of the distribution’s tails. The classical results in this area are stated assuming global regularity conditions on the coefficients of the SDE: an assumption which fails to be fulfilled by several financial models, whose coefficients involve square-root or other non-Lipschitz continuous functions. Then, in the first part of this thesis (chapters 2, 3 and 4) we study the existence, smoothness and space asymptotics of densities when only local conditions on the coefficients of the SDE are considered. Our analysis is based on Malliavin calculus tools and on tube estimates for Itô processes, namely estimates on the probability that an Itô process remains around a deterministic curve up to a given time. We give applications of our results to general classes of option pricing models, including generalisations of CIR and CEV processes and Local Stochastic Volatility models. In the latter case, the estimates we derive on the law of the underlying price have an impact on moment explosion and, consequently, on the large-strike asymptotic behaviour of the implied volatility. Implied volatility modeling, in its turn, makes the object of the second part of this thesis (chapters 5 and 6). We deal with some questions related to the issue of an efficient and economical parametric modelisation of the volatility surface. We focus on J. Gatheral’s SVI model, first tackling the problem of its calibration to the market smile. We propose an effective quasi-explicit calibration procedure and display its performances on financial data. Then, we analyse the capability of SVI to generate efficient time-dependent approximations of symmetric smiles, providing the corresponding numerical applications in the framework of the Heston stochastic volatility model.

Abstract (sommario):

Primate lentiviruses (PLVs), including human immunodeficiency virus type 1 (HIV-1), HIV type 2 (HIV-2), and the simian immunodeficiency viruses (SIVs), cause persistent lifelong infections despite the presence of virus-specific adaptive immune responses. The target of antibodies is the viral envelope glycoprotein (Env), which is expressed on the surface of virions and infected cells as a trimer of gp120:gp41 heterodimers. SIV env sequence variation arising from evasion of antibodies is well established and closely mimics the pattern observed in HIV-infected human patients, yet despite the experimental advantages of the macaque model, the viral dynamics during acute and early infection leading to escape within env have not been well defined. To examine the evolutionary dynamics of SIV env during early infection (< 6 months post-infection), we obtained longitudinal plasma samples from a small cohort of SIVmac251-infected rhesus macaques. We deep-sequenced the env gene from longitudinal samples spanning acute and early infection (2-29 weeks post-infection) from four SIV-infected rhesus macaques and the inoculum (a swarm stock of uncloned SIVmac251) that was used to infect the cohort (by repeated low-dose challenge). Using high-resolution next generation sequencing (NGS), we captured a population bottleneck at the point of transmission from the stock into each animal, tracked the subsequent emergence of Env diversity from the initially homogeneous population, and correlated changes with the onset of Env-specific antibodies. We identified a pattern of common substitutions, insertions, and deletions in env of animals with antibody responses, which repeatedly emerge in SIV-infected primate hosts, and found that adaptive changes clustered within short regions of the V1 and V4 loops of gp120. Surprisingly, we found multiple large in-frame deletions in V4 emerge to become dominant in the viral population in two animals with detectable antibody responses to Env. Furthermore, we developed a novel deep sequencing based viral fitness assay (Fit-Seq) and measured the relative fitness of several key in vivo antibody escape adaptations. Using Fit-Seq, we found that Env adaptations in V1 and V4 that confer antibody escape had no associated fitness costs in the absence of antibody, but rather, replicated to the same level as SIVmac239 WT. Surprisingly, we also found that Fit-Seq was able to detect antibody-mediated neutralization of SIVmac239 even in cases where activity was undetectable by standard neutralization assays. Our observation of reproducible patterns of Env variation clustered in V1 and V4, together with measurements of relative fitness, suggest that antibody responses can select for mutations that confer viral escape yet have little or no associated replicative fitness cost in the absence of antibody, even while providing a clear fitness advantage in the environment of constant antibody selection encountered in vivo. Thus, sites that can change with little or no impact on relative fitness may have evolved as an immune evasion mechanism to facilitate rapid and early escape from Env-specific antibody.

Abstract (sommario):

I studien undersöks hur svensklärare bedömer samt hur de resonerar kring sva-elevers språk och stil i det nationella provets skriftliga delprov på gymnasiet. Följande två frågeställningar har ställts: Hur bedömer sve-lärare sva-elevers texter utifrån kriteriet “språk och stil” - individuellt och i en sambedömning? Hur resonerar bedömarna? Utgångspunkten har varit att gruppindelning av elever med ett andraspråk är svårt och att det finns olika inriktningar eller diskurser (Hedman & Magnusson, 2018) inom forskningsfältet svenska som andraspråk som har olika lösningar på hur ämnet skall organiseras. En annan utgångspunkt för undersökningen är att språksyn är avgörande för hur sva-elevers språk bedöms och tidigare forskning har bl.a. visat att andraspråkselever förfördelas i ett skolsystem där inlärarspråk bedöms utifrån standardsvenska normer.En arrangerad bedömning har genomförts där två lärare i sve1 bedömt sex redan bedömda texter, skrivna av elever i sva1. Lärarnas bedömning och resonemang kring bedömningen har spelats in i s.k. Think Aloud Protocols vars innehåll sedan analyserats och kopplats till språksyn och de olika sva-diskurserna.Resultatet av studien är att alla sva-texter förutom en får ett lägre betyg med bedömningskriterierna för sve1 än med dem för sva1. Ingen text får högre betyg än E och två texter underkänns, en av dessa med betyget A i sva1. Texterna får också högre betyg på delaspekten stil än på delaspekten språk. Lärarna är samstämmiga i sina bedömningar och reagerar på samma feltyper i sva-elevernas texter. Avvikelser som noteras av lärarna och som påverkar bedömningen negativt är framförallt formfel, ordföljdsfel och brister i ordförråd. Sammantaget menar bedömarna att elevtexterna, pga dessa språkfel, har svårt att uppnå betygskriteriernas krav i sve1 om att i huvudsak följa skriftspråkets normer. Vidare upplever lärarna rättningen som mentalt krävande men visar samtidigt prov på förståelse för andraspråksvarieteten. Undersökningen visar att till syvende och sist är det betygskriterierna som är det största hindret mellan elevtexten och ett högre betyg än E. Resultaten i studien pekar också mot att om gymnasiets sva-kurser skall modifieras eller eventuellt smälta samman med kursen svenska bör en sådan kursändring föregås av noggranna avväganden. Annars riskerar sva-eleverna att missgynnas utbildnings- och betygsmässigt.

Abstract (sommario):

The thesis is an ethnohistorical study of one major pilgrimage site in Sri Lanka, known as Sri Pada (Adam’s Peak), where hundreds of thousands of pilgrims annually visit to worship the sacred footprint where is looted in the mountain top temple. This sacred footprint has different sacred connotations for Sri Lanka’s major religious groups (Buddhists, Hindus, Muslims and Catholic). However, this pilgrimage site, which was considered a multi-religious site until the turn of the twentieth century, has now been constructed or ordered into an ethnic majoritarian Buddhist space. My thesis, therefore, concentrates in part on the historical process which has led to the construction of the pilgrimage site as a Buddhist space, and then locates this process within the wider context of the rise of Sinhala Buddhist nationalism in Sri Lankan. My work highlights the powerful role pilgrimage can play in particular religious discourses and the manner it legitimates certain ways of envisaging power and relationships of domination at particular conjunctures, which is clearly apparent in the contemporary Sinhala Buddhist cultural nationalism in Sri Lanka. This thesis is divided into three interconnected parts. The first part considers ‘knowledge production’ about Sri Pada while the second part explores the major competing discourses that have been arisen during its political and religious history. The final part is mainly focused on the style of religiosity and the social composition of pilgrims, and explores social factors in the practices of worship. One chapter deals with the style of “official” Buddhist religiosity found at this centre and two further chapters look at devotional and expressive forms of religiosity of pilgrims, which is oriented to the Buddha rather than the gods and as such is markedly different from that documented by anthropologists working in other parts of the island. The final chapter investigates links between devotional styles and the shifting socio-political contexts. The documentation of the prevailing styles of religiosity at Sri Pada enable me to show on one hand how such religiosity further undermines the broadly Weberian antinomies that have dominated the anthropology of Buddhism in Sri Lanka, and on the other hand the intensity or scale of Buddhicization of the historically viewed ‘sacred site’.

Abstract (sommario):

La littérature et la psychanalyse entretiennent des liens aussi inéluctables qu'énigmatiques. Freud le premier s'est attaché à montrer ce qui, de l'entreprise d'écriture, pouvait permettre de comprendre les faits psychanalytiques, d'en comprendre les mécanismes et de les illustrer. Il a tiré de nombreux enseignements des pratiques artistiques, particulièrement des oeuvres littéraires et, après lui, le recours aux oeuvres d'art a permis de repérer des enjeux difficiles voire impossibles à repérer dans le seul champ de la clinique. De leur côté, les écrivains se sont emparés des concepts et des méthodes psychanalytiques pour nourrir leur perpétuelle quête d'une plus grande connaissance de soi quand il ne s'agissait pas, pour eux, de faire de l'écriture une arme contre la mort. Ce travail interroge ce qui motive un individu à passer à l'acte d'écrire, d'où procède ce désir et comment, par quels procédés il le met en oeuvre. Si l'écriture peut, à l'occasion organiser le discours analytique, celui-ci a incontestablement bouleversé les codes artistiques, et ce, dans le domaine littéraire en particulier. L'écriture, en mobilisant les processus inconscients et grâce aux résonances qu'elle laisse se déployer permet, par des voies qui lui sont propres, d'aller aux sources de l'inconscient. C'est dans l'élaboration de formes nouvelles que ceux qui nous intéressent sont parvenus à façonner, à cerner, ce qui, de leur identité faisait défaut à leur propre compréhension et à leur appréhension du réel
Literature and psychoanalysis hold together links so inevitable as enigmatic writers. Freud was the first to show and illustrate how the writing process could make understand the psychoanalytic facts and their mechanisms He learned a lot from artistic practices, particularly in literature; and after him, the use of literature allowed the identification of issues in the clinical field, which were likely to be then transferred to the medical practice. From their side, the writers have taken the psychoanalytic concepts and approaches to enrich and feed their perpetual quest for an always-greater self-knowledge. Most have even used writing as a weapon against death. It seemed interesting to us to test some artworks in terms of analytical thinking. Therefore the following essay asks the question on what motivates an individual to get involved in writing, where does the desire, often a matter of survival, come from, and how does he proceed to achieve that. If writing can occasionally organize the analytic discourse, it is undeniable that it has profoundly affected the artistic codes, and in particular in the field of literature. Writing process, through mobilization of unconscious processes and resonances it leaves, enables, by way of its own, to go to the sources of the unconscious. It is in the development of new forms of interest that the studied writers were able to shape, identify which of their identity aspects was lacking in their own understanding of reality
