For well over half a century, British TV drama production has both inherited from and aimed to appeal to nations and cultures beyond the UK, particularly the lucrative (yet notoriously tough) US TV market. However, in the context of mainstream American broadcasting, British-produced imports have never been anything more than a peripheral presence on US small screens. A currently prominent production strategy aiming to counter the mainstream US TV market's aversion to foreign-sourced drama, in an attempt to access prime-time broadcasting positions, is a process which can be labelled as UK-to-US TV drama ‘translation’: the ‘recreation’ of British-based dramas within an American cultural framework. Whilst the cultural reconfiguration of game show and reality/lifestyle TV formats has received heightened critical attention in recent years, investigation into the international translation of TV drama remains less developed. This paper investigates both the internal textual operations and the external production dynamics involved in the process of UK-to-US TV drama translation, drawing on direct interview material from industry professionals. The UK and US versions of the crime drama Cracker constitute the core translation case study, utilising the close analysis of text and production context as a lens through which to examine the mechanics of UK-to-US TV drama translation.

Crisis communication is a widely treated field. There are lot of works and guides which provide helpful information in order to face crisis situations successfully (Alcat, 2005, Benoit, 1997) and articles about case studies (Nespereira, 2014, Blaney y Benoit 2001). Nonetheless, most of times, these guides are focused on business or corporations (Abeler, 2010) and there are not such information about crisis communications in politics (Gaspar e Ibeas, 2015). The field is smaller if we speak about forgiveness as restoration image tool in politics (Harris 2006). Despite all, we live in “forgiveness era” as Krauze said (1998) where people demand to politicians to apologize when they have mistakes (Harris et al. 2006:716). So, we will try to make an approach to forgiveness in politics as a image restoration tool and analyze its capabilities in order to face crisis management.

Auctions have become popular as means of allocating emissions permits in the emissions trading schemes developed around the world. Mostly, only a subset of the regulated polluters participate in these auctions along with speculators, creating a market with relatively few participants and, thus, incentive for strategic bidding. I characterize the bidding behavior of the polluters and the speculators, examining the effect of the latter on the profits of the former and on the auction outcome. It turns out that in addition to bidding for compliance, polluters also bid for speculation in the aftermarket. While the presence of the speculators forces the polluters to bid closer to their true valuations, it also creates a trade-off between increasing the revenue accrued to the regulator and reducing the profits of the auction-participating polluters. Nevertheless, the profits of the latter increase in the speculators' risk aversion.

This paper provides the first investigation about bond mutual fund performance during recession and expansion periods separately. Based on multi-factor performance evaluation models, results show that bond funds significantly underperform the market during both phases of the business cycle. Nevertheless, unlike equity funds, bond funds exhibit considerably higher alphas during good economic states than during market downturns. These results, however, seem entirely driven by the global financial crisis subperiod. In contrast, during the recession associated to the Euro sovereign debt crisis, bond funds are able to accomplish neutral performance. This improved performance throughout the debt crisis seems to be related to more conservative investment strategies, which reflect an increase in managers’ risk aversion.

Cette thèse porte sur l’effet du risque de prix sur la décision des agriculteurs et les transformateurs québécois. Elle se divise en trois chapitres. Le premier chapitre revient sur la littérature. Le deuxième chapitre examine l’effet du risque de prix sur la production de trois produits, à savoir le maïs grain, la viande de porc et la viande d’agneau dans la province Québec. Le dernier chapitre est centré sur l’analyse de changement des préférences du transformateur québécois de porc pour ce qui est du choix de marché. Le premier chapitre vise à montrer l’importance de l’effet du risque du prix sur la quantité produite par les agriculteurs, tel que mis en évidence par la littérature. En effet, la littérature révèle l’importance du risque de prix à l’exportation sur le commerce international. Le deuxième chapitre est consacré à l’étude des facteurs du risque (les anticipations des prix et la volatilité des prix) dans la fonction de l’offre. Un modèle d’hétéroscédasticité conditionnelle autorégressive généralisée (GARCH) est utilisé afin de modéliser ces facteurs du risque. Les paramètres du modèle sont estimés par la méthode de l’Information Complète Maximum Vraisemblance (FIML). Les résultats empiriques montrent l’effet négatif de la volatilité du prix sur la production alors que la prévisibilité des prix a un effet positif sur la quantité produite. Comme attendu, nous constatons que l’application du programme d’assurance-stabilisation des revenus agricoles (ASRA) au Québec induit une plus importante sensibilité de l’offre par rapport au prix effectif (le prix incluant la compensation de l’ASRA) que par rapport au prix du marché. Par ailleurs, l’offre est moins sensible au prix des intrants qu’au prix de l’output. La diminution de l’aversion au risque de producteur est une autre conséquence de l’application de ce programme. En outre, l’estimation de la prime marginale relative au risque révèle que le producteur du maïs est le producteur le moins averse au risque (comparativement à celui de porc ou d’agneau). Le troisième chapitre consiste en l’analyse du changement de préférence du transformateur québécois du porc pour ce qui est du choix de marché. Nous supposons que le transformateur a la possibilité de fournir les produits sur deux marchés : étranger et local. Le modèle théorique explique l’offre relative comme étant une fonction à la fois d’anticipation relative et de volatilité relative des prix. Ainsi, ce modèle révèle que la sensibilité de l’offre relative par rapport à la volatilité relative de prix dépend de deux facteurs : d’une part, la part de l’exportation dans la production totale et d’autre part, l’élasticité de substitution entre les deux marchés. Un modèle à correction d’erreurs est utilisé lors d’estimation des paramètres du modèle. Les résultats montrent l’effet positif et significatif de l’anticipation relative du prix sur l’offre relative à court terme. Ces résultats montrent donc qu’une hausse de la volatilité du prix sur le marché étranger par rapport à celle sur le marché local entraine une baisse de l’offre relative sur le marché étranger à long terme. De plus, selon les résultats, les marchés étranger et local sont plus substituables à long terme qu’à court terme.

Elastic Octopus was inspired by a perceived increased reluctance in student attitudes towards taking risks and failure in design innovation. In particular, recent trends in funding and risk-aversion in earlier phases of education where failures are discouraged has limited the potential for ground breaking innovative thinking. This experimental design project was conceived to tackle the failure reluctance trend by developing a team based cross-disciplinary masters level design innovation studio module where students would succeed in relation to their capacity to demonstrate failure. Principally this involved creating a permission giving process where ambitious design experiments are developed in order to encourage the transgression of edges and boundaries. This was achieved by adapting a number of creative design methods including blue-sky thinking, back casting and design exorcisms to challenge and de-programme failure aversion. Succeeding through failure involved transitioning from meta-themes through to experimental contexts where failures could be attempted as a way of exploring the limits of technologies, structures, mental models, human engagement and other factors critical to success. We hope that insights gained from this disruptive educational module can offer unexpected benefits for students ranging from increased failure resilience, through to narrative generation and context forming skills while at the same time providing wider value in discussing how designers deal with failure.

Qui n'a jamais demandé à un jeune enfant: "Que feras-tu lorsque tu seras grand?", ou encore à une personne nouvellement rencontrée: "Que faites-vous dans la vie"? Faire quelque chose c'est travailler, avoir un métier, exercer une profession. Toute la jeunesse est axée sur l'éventualité d'un travail. L'âge adulte est "destiné" à s'acquitter, au sein de la société, à un rôle utile qui sera, nous l'espérons tous, valorisant. "Le travail c'est la santé!", comme le dit l'adage. Alors pourquoi ne pas faire quelque chose de beau, de grandiose? Au début de la vie de travail tous les espoirs sont permis. Quoi qu'il en soit, la vision sociale favorise tout de même les activités qui seront empreintes de productivité, d'utilité, de rapidité, etc. En fait, toute la vie est construite vers un devenir de travailleuse et de travailleur à part entière. Alors qu'advient-il lorsque nous nous retirons de la vie de travail? Que se produit-il lorsque la santé, l'esprit, la perte de motivations et d'intérêts et même la société font en sorte que la personne est classée "inapte à travailler''. Mais attention, l'utilisation du terme "inaptitude" ne signifie pas que la personne a perdu tous ses moyens, malgré que cela peut être le cas, mais plutôt qu'il est temps de se retirer, de laisser sa place "aux plus jeunes". La joie, la peine, l'euphorie, le désespoir sont autant d'émotions paradoxales que l'individu à la retraite peut ressentir. La vie de travail, presqu'adulée auparavant, est dès lors perçue soit avec du regret ou encore avec une libération de contraintes. La personne peut transposer son nouvel état comme à une rédemption ou, paradoxalement, comme un gouffre qui s'ouvre sous ses pieds. Dans un cas comme dans l'autre, cette dernière se retrouve trop souvent devant un fait accompli et elle ne sait trop comment "organiser'' son espace et son temps. Dès lors, comment compléter la transition du monde du travail vers celui de la retraite? Nous voulons par cet essai, bien modestement nous l'avouons, répondre à cette question. Comme professionnelle de l'orientation nous sommes sensible à la qualité de vie au travail de la personne. Cependant, nous ne croyons pas qu'il est possible de dissocier la vie professionnelle d'une personne de sa vie personnelle. Alors donc, nous sommes convaincue que les professionnelles et professionnels de l'orientation se doivent de lier les diverses facettes de la vie de leurs clientes et clients. Ceci s'avère encore plus vraisemblable lorsque l'objet de nos intérêts se portent sur le départ du monde du travail, c'est-à-dire la transition entre le travail et la retraite. C'est donc suite à de nombreuses lectures et de nombreux questionnements que nous suggérons un cheminement lors de cette transition. Tout d'abord nous examinons la vision sociale portée sur la retraite et comment cette dernière influence la vie pendant cette transition. Par la suite, nous établirons la problématique inhérente à cette traversée. Problématique pouvant paraître simple à première vue, mais qui est en fait un enchevêtrement de sentiments, d'émotions, de désirs et de buts individualisés permettant des regroupements certes, dans laquelle persiste une complexité issue de sa propre nature. Troisièmement, diverses théories du développement psychologique, psychosocial et vocationnel seront résumées pour nous permettre d'établir les assises de notre vision de la transition travail-retraite. Cette spécification rend possible l'établissement de la perception théorique de la vieillesse et du vieillissement et supporte les pensées pour éviter qu'elles ne deviennent que des idéologies. Les théories décrites nous amènent à en retenir une, celle de Bridges (1980), qui introduit les notions de deuil, de bilan et de projet. En effet, les périodes d'achèvement, de zone neutre et de commencement ou création sont, à notre avis, le coeur d'une transition comme celle de la retraite. Nous élaborerons plus longuement sur l'implication de ces phases pendant la transition et du rôle pour les conseillères et conseillers d'orientation, pour finalement présenter un programme préliminaire, servant d'assise à un programme de formation. Nous croyons que l'établissement des objectifs, du format, des séquences d'apprentissage, du matériel pédagogique, des méthodes et des stratégies d'évaluation peut être grandement utile pour toutes professionnelles ou pour tous professionnels désirant construire une situation éducative favorisant le passage du monde complexe du travail vers celui, souvent encore plus complexe, de la retraite.

A literacia financeira é uma questão que tem vindo a ganhar relevância nos últimos anos e preocupado os governantes e instituições financeiras a nível mundial. De uma forma geral, o nível de conhecimento financeiro dos indivíduos no mundo é baixo, mesmo em países cujos mercados e economia são desenvolvidos. Existem diferenças a nível da literacia financeira não só entre países, como também dentro dos próprios países. Ao longo dos anos, várias pesquisas indicam que existem fatores socioeconómicos e demográficos que condicionam o nível de literacia financeira e podem explicar as diferenças existentes. A educação financeira tem sido a estratégia usada pelos governos para aumentar o nível de conhecimento financeiro dos indivíduos. Contudo, as opiniões dos autores dividem-se, quanto à sua real eficácia, sendo que alguns consideram que esta não é a melhor alternativa a seguir. A literacia financeira exerce influência sobre o comportamento dos indivíduos. Além disso, o comportamento dos indivíduos é condicionado por enviesamentos cognitivos e emocionais (excesso de confiança, aversão ao risco,etc.) que os afasta da racionalidade completa defendida pelas Finanças Tradicionais. Assim, surge uma nova área de estudo - as Finanças Comportamentais. Como é já vasta a literatura que emergiu à volta desta temática, esta dissertação apresenta uma revisão da literatura sobre a literacia financeira, abordando os aspectos comportamentais bem como a questão da educação financeira e dos programas que têm sido conduzidos para a promover.

In the past decade, systems that extract information from millions of Internet documents have become commonplace. Knowledge graphs -- structured knowledge bases that describe entities, their attributes and the relationships between them -- are a powerful tool for understanding and organizing this vast amount of information. However, a significant obstacle to knowledge graph construction is the unreliability of the extracted information, due to noise and ambiguity in the underlying data or errors made by the extraction system and the complexity of reasoning about the dependencies between these noisy extractions. My dissertation addresses these challenges by exploiting the interdependencies between facts to improve the quality of the knowledge graph in a scalable framework. I introduce a new approach called knowledge graph identification (KGI), which resolves the entities, attributes and relationships in the knowledge graph by incorporating uncertain extractions from multiple sources, entity co-references, and ontological constraints. I define a probability distribution over possible knowledge graphs and infer the most probable knowledge graph using a combination of probabilistic and logical reasoning. Such probabilistic models are frequently dismissed due to scalability concerns, but my implementation of KGI maintains tractable performance on large problems through the use of hinge-loss Markov random fields, which have a convex inference objective. This allows the inference of large knowledge graphs using 4M facts and 20M ground constraints in 2 hours. To further scale the solution, I develop a distributed approach to the KGI problem which runs in parallel across multiple machines, reducing inference time by 90%. Finally, I extend my model to the streaming setting, where a knowledge graph is continuously updated by incorporating newly extracted facts. I devise a general approach for approximately updating inference in convex probabilistic models, and quantify the approximation error by defining and bounding inference regret for online models. Together, my work retains the attractive features of probabilistic models while providing the scalability necessary for large-scale knowledge graph construction. These models have been applied on a number of real-world knowledge graph projects, including the NELL project at Carnegie Mellon and the Google Knowledge Graph.

This PhD thesis contains three main chapters on macro finance, with a focus on the term structure of interest rates and the applications of state-of-the-art Bayesian econometrics. Except for Chapter 1 and Chapter 5, which set out the general introduction and conclusion, each of the chapters can be considered as a standalone piece of work. In Chapter 2, we model and predict the term structure of US interest rates in a data rich environment. We allow the model dimension and parameters to change over time, accounting for model uncertainty and sudden structural changes. The proposed timevarying parameter Nelson-Siegel Dynamic Model Averaging (DMA) predicts yields better than standard benchmarks. DMA performs better since it incorporates more macro-finance information during recessions. The proposed method allows us to estimate plausible realtime term premia, whose countercyclicality weakened during the financial crisis. Chapter 3 investigates global term structure dynamics using a Bayesian hierarchical factor model augmented with macroeconomic fundamentals. More than half of the variation in the bond yields of seven advanced economies is due to global co-movement. Our results suggest that global inflation is the most important factor among global macro fundamentals. Non-fundamental factors are essential in driving global co-movements, and are closely related to sentiment and economic uncertainty. Lastly, we analyze asymmetric spillovers in global bond markets connected to diverging monetary policies. Chapter 4 proposes a no-arbitrage framework of term structure modeling with learning and model uncertainty. The representative agent considers parameter instability, as well as the uncertainty in learning speed and model restrictions. The empirical evidence shows that apart from observational variance, parameter instability is the dominant source of predictive variance when compared with uncertainty in learning speed or model restrictions. When accounting for ambiguity aversion, the out-of-sample predictability of excess returns implied by the learning model can be translated into significant and consistent economic gains over the Expectations Hypothesis benchmark.

Virtual-build-to-order (VBTO) is a form of order fulfilment system in which the producer has the ability to search across the entire pipeline of finished stock, products in production and those in the production plan, in order to find the best product for a customer. It is a system design that is attractive to Mass Customizers, such as those in the automotive sector, whose manufacturing lead time exceeds their customers' tolerable waiting times, and for whom the holding of partly-finished stocks at a fixed decoupling point is unattractive or unworkable. This paper describes and develops the operational concepts that underpin VBTO, in particular the concepts of reconfiguration flexibility and customer aversion to waiting. Reconfiguration is the process of changing a product's specification at any point along the order fulfilment pipeline. The extent to which an order fulfilment system is flexible or inflexible reveals itself in the reconfiguration cost curve, of which there are four basic types. The operational features of the generic VBTO system are described and simulation is used to study its behaviour and performance. The concepts of reconfiguration flexibility and floating decoupling point are introduced and discussed.

The area of Notting Hill in west London has been subject to much media coverage in recent years, which, along with substantial gentrification, has given rise to an image of the area as the epitome of fashionable London. This study investigates the views of those marginal to gentrification and mediated representation on their feelings about the local area, its image and their changing neighbourhoods. Many participants in the research resented some of the more recent changes in Notting Hill and the area's representation in the media. However, in contrast to expectations, most of the more working-class respondents involved in the research did not articulate much emotional attachment to the area. They were more concerned with what might be termed the material aspects of life in Notting Hill: convenience, facilities, safety and so on. In contrast, the more middle-class respondents frequently spoke of their regret of the changes to the area, such as the loss of independent shops, and the reduction in diversity. Paradoxically, the loss of working-class landscapes seems a relatively middle-class worry. The symbolically important landscapes described by working-class respondents were related to more immediate, material issues, in which gentrification was only a relatively minor concern.
