Clear hero and dark hero in the cinematographic narration

The role of the hero is changing, slightly irregular, but it’s purpose is constant. The line that separates good from evil is frequently so thin that sometimes the main hero can act in a negative way, casting doubts about his own nature in the pursuit of good. This paper aims to inquire into the character’s heroic condition showing two variations of this archetype in the context of postmodern cinema: the “clear hero”, and the “dark hero”. The former keeps the most traditional values of the hero, while the latter provides a dimension which distinguishes it from the previous one: his experience executing evil as a part of his process to heroici­ty. Postmodernity implies an ambivalence in the character’s identity which can be comparable to the hero’s role, and to his way of making good. The “clear hero” does not imply negative features in the active nature of the hero, whilst the “dark hero” does include them. Through the protagonists of Gladiator (Scott, 2000) and Batman Begins (Nolan, 2005) are offered both heroic perspectives based on a selection of their principal ac­tions which have been subjected to analysis according to some parameters: behavior, implication, and cause. The decisive action will also be signalized, according to the narration’s teleonomy in reason of the favorable or unfavorable sense for the hero. Finally, each character will be observed from its archetype. By analyzing their actions from these perspectives, we observe the clear hero and the dark hero as affordable categories for the heroic role.

Contrasting global genetic patterns in two biologically similar, widespread and invasive Ciona species (Tunicata, Ascidiacea)

Human-mediated dispersal interplays with natural processes and complicates understanding of the biogeographical history of species. This is exemplified by two invasive tunicates, Ciona robusta (formerly Ciona intestinalis type A) and C. intestinalis (formerly Ciona intestinalis type B), globally distributed and sympatric in Europe. By gathering new mitochondrial sequences that were merged with published datasets, we analysed genetic patterns in different regions, with a focus on 1) their sympatric range and 2) allopatric populations in N and S America and southern Europe. In the sympatric range, the two species display contrasting genetic diversity patterns, with low polymorphism in C. robusta supporting the prevalent view of its recent introduction. In the E Pacific, several genetic traits support the non-native status of C. robusta. However, in the NE Pacific, this appraisal requires a complex scenario of introduction and should be further examined supported by extensive sampling efforts in the NW Pacific (putative native range). For C. intestinalis, Bayesian analysis suggested a natural amphi-North Atlantic distribution, casting doubt on its non-native status in the NW Atlantic. This study shows that both natural and human-mediated dispersal have influenced genetic patterns at broad scales; this interaction lessens our ability to confidently ascertain native vs. non-native status of populations, particularly of those species that are globally distributed.

Commentary on the Statute of Monopolies 1624

Legislation restricting the monarch's ability to make monopoly grants in accordance with the royal prerogative, and providing a statutory basis for the patent system. The legislation established the basis upon which patents for "new manufacture[s]" might be granted to "the true and first inventor" of the same in furthering the interests of industry, the economy, and the state. At the same time, privileges concerning printing were left unaffected by the legislation, as were those for the manufacture of saltpetre or gunpowder and for the casting and making of ordnance (canons). In limiting the term of protection for future patents to 14 years while confining existing patents for the same to a period of 21 years, the legislation influenced the choice of the two copyright terms in the Statute of Anne 1710.

Fabrication and characterization of SSZ tape cast electrolyte-supported solid oxide fuel cells

A 10 mol%Sc₂O₃, 1 mol%CeO₂ stabilized-ZrO₂ (SSZ) powder was successfully prepared using the sol-gel method. Subsequent SSZ electrolyte pellets were prepared by tape casting technique and sintered at 1400 °C, 1450 °C, 1500 °C, 1550 °C and 1600 °C. These were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and electrochemical impedance spectroscopy (EIS). SSZ showed a pure cubic phase after sintering, the grain size of SSZ increased with the increase of sintering temperature. The SSZ sintered at 1550 °C showed the highest ion conductivity. The maximum power densities of Ni-SSZ/SSZ/La_0.8Sr_0.2MnO_3-δ (LSM)-SSZ single cells sintered at 1550 °C were 0.18, 0.36, 0.51 and 0.72 W cm^-2 at 650, 700, 750 and 800 °C, respectively. The polarization resistance (R_p) of the single cell attained 0.201 Ω cm² at 800 °C.

Rotary moulding of ceramic hollow wares

A novel processing method for the fast and economic production of hollow ceramic components has been developed by combining in situ coagulation moulding with a modified version of the technique of rotary moulding[Binner, J. G. P., Al-Dawery, I. A., Tari, G. and Yan, Y., Rotary casting technique. UK Patent application No. 0506349.0, March 2005], the latter being adapted from the polymer industry. The process was found to require a high solids content suspension, hence development work was performed in this direction though in the end a new, commercial suspension was utilised. Of the three forming routes of gel casting, direct coagulation casting and in situ coagulation moulding, the latter was found to be the most promising for the new process of rotary moulding of ceramics. Due to the low value of clay-based ceramics, a new low cost coagulant was identified and the effect of lactone concentration and temperature on setting time determined. Following substantial optimisation work, it was found that a two-speed approach to multi-axial rotation was the most successful; medium sized cream jugs could be produced in just 7 min. With respect to mould materials, the porous resin normally used for pressure casting of sanitary ware was found to be the best option, though since this is quite expensive conventional plaster-of-paris moulds were found to be a suitable material to enable companies, particularly SMEs, to become familiar with the technology whilst avoiding high costs for trials. The processed articles could be successfully fired and glazed using gas-fired kilns with no sign of any black cores. Major advantages of the process include the ability to precisely calculate the amount of ceramic slip required, eliminating either slip wastage or the need to pour used slip back into the virgin material as currently happens with slip casting. In addition, since the precursor suspension has a very high solids content, the time and energy required to dry the green product and associated moulds has been considerably reduced. © 2008 Elsevier Ltd.

Pyramus and Thisbe 4 You or a "Wondrous Strange" Tale of Contemporary Romanian Theatre

Like its title, Pyramus and Thisbe 4 You, Alexandru Dabija’s production at the Odeon Theatre, Bucharest, was a tongue-in-cheek invitation to the audience that at once aimed to tease past and recent Romanian endeavours and to tease out the stage potential a Shakespeare play holds today. My examination of the production re-constructs the local cultural contexts the production plays with and against, referring to the Romanian ways of making Shakespeare this production enters into dialogue with. Take 1, an all-female version casting the mature stars of the Odeon, I read against both Elizabethan all-male stage practice and Andrei Serban’s all-female Lear at the Bulandra (2008). Take 2, “an old device” (V.1.50): a teacher-student “devising” session at the Academy of Theatre and Cinema, I read against critics’ “more strange than true” (V.1.2) parlance on “theories of perception and reception” and against hi-tech Shakespeare dominating the Romanian stages in the first decade of the third millennium. Take 3, local political banter on ethnic discrimination, I read as “satire keen and critical” (V.1.54) on both communist censorship and the recent rise of nationalism in Romania. Take 4, a “cold” reading-cum-improvisation performed by the technical crew – this production’s mechanicals – I read as “palpable-gross play” (V.1.376) on both acting and spectating practices. What I argue in this article is that Dabija’s production goes beyond its local context and mores, and proposes a re-assessment of Shakespeare’s cultural currency in (European) Romania and Europe at large by exposing current tyrannies in Shakespeare studies: from translation and adaptation, through directing and acting, to viewing and reviewing.

The Elastic Octopus: A Catalogue of Failures for Disrupting Design Eduction

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.

The development of dynamic CFD model of the magnetic semi-levitation of liquid metals

In the casting of reactive metals, such as titanium alloys, contamination can be prevented if there is no contact between the hot liquid metal and solid crucible. This can be achieved by containing the liquid metal by means of high frequency AC magnetic field. A water cooled current-carrying coil, surrounding the metal can then provide the required Lorentz forces, and at the same time the current induced in the metal can provide the heating required to melt it. This ‘attractive’ processing solution has however many problems, the most serious being that of the control and containment of the liquid metal envelope, which requires a balance of the gravity and induced inertia forces on the one side, and the containing Lorentz and surface tension forces on the other. To model this process requires a fully coupled dyna ic solution of the flow fields, magnetic field and heat transfer/melding process to account for. A simplified solution has been published previously providing quasi-static solutions only, by taking the irrotational ‘magnetic pressure’ term of the Lorentz force into account. The authors remedy this deficiency by modelling the full problem using CFD techniques. The salient features of these techniques are included in this paper, as space allows.

Three-dimensional free surface modelling in an unstructured mesh environment for metal processing applications

In the casting of metals, tundish flow, welding, converters, and other metal processing applications, the behaviour of the fluid surface is important. In aluminium alloys, for example, oxides formed on the surface may be drawn into the body of the melt where they act as faults in the solidified product affecting cast quality. For this reason, accurate description of wave behaviour, air entrapment, and other effects need to be modelled, in the presence of heat transfer and possibly phase change. The authors have developed a single-phase algorithm for modelling this problem. The Scalar Equation Algorithm (SEA) (see Refs. 1 and 2), enables the transport of the property discontinuity representing the free surface through a fixed grid. An extension of this method to unstructured mesh codes is presented here, together with validation. The new method employs a TVD flux limiter in conjunction with a ray-tracing algorithm, to ensure a sharp bound interface. Applications of the method are in the filling and emptying of mould cavities, with heat transfer and phase change.

Shakespeare and the Re/Vision of Indian Heritage in the Postcolonial British Context

As part of the 2012 World Shakespeare Festival, the Royal Shakespeare Company staged a production of Much Ado About Nothing set in India. Shakespeare’s Messina in sixteenth century Italy was transposed to twenty-first century Delhi and with a company of actors who were all of Indian heritage. The casting of individual British Asian actors in mainstream UK productions of Shakespeare is no longer unusual. What was unprecedented here, however, was that not only was the entire cast ‘Asian’ but the director was not, as is standard practice, a leading member of the white British theatrical establishment. Instead the director, Iqbal Khan, is the son of a Pakistani father who migrated to England in the 1960s. I use the term ‘Indian heritage’ with great caution conscious that what began under the British Raj in nineteenth century India led through subsequent economic imperatives and exigencies, and political schism to a history of migratory patterns which means that today’s British Asian population is a complex demographic construct representing numerous different languages and cultural and religious affiliations. The routes which brought those actors to play imagined Indian Shakespeare in Stratford-upon-Avon in July 2012 were many and various. I explore in this chapter the way in which that complexity of heritage has been brought to bear on the revisioning of Shakespeare by British Asian theatre makers operating outside the theatrical mainstream. In general because of the social, economic and institutional challenges facing British Asian theatre artists, the number of independent professional companies is comparatively small and for the most part, their work has focused on creating drama which interrogates thorny questions of identity formation and contemporary cultural practices within the ‘new’ British Asian communities. Nevertheless for artists born and/or educated in the UK the Western classical canon, including of course Shakespeare, is as much part of their heritage as the classical Indian narratives and performance traditions which so powerfully evoke collective memories of the lost ‘home’ of their elders. By far the most consistent engagement with Shakespeare has been seen in the work of Tara Arts which was the first British Asian theatre company set up in 1977. The artistic director Jatinder Verma brings his own ‘transformed and translated’ heritage as an East African-born, Punjabi-speaking, English-educated, Indian migrant to the UK to plays as diverse as A Midsummer Night’s Dream, Troilus and Cressida , The Tempest and The Merchant of Venice. I discuss examples of Tara productions in the light of the way Shakespeare’s plays have been used to forge both creative synergies between parallel cultures and provide a means of addressing the ontological ruptures and dislocations associated with the colonial past.

Modélisation du comportement des bétons fibrés à ultra-hautes performances par la micromécanique : Effet de l'orientation des fibres à l'échelle de la structure

Cette thèse s’inscrit dans le contexte d’une optimisation industrielle et économique des éléments de structure en BFUP permettant d’en garantir la ductilité au niveau structural, tout en ajustant la quantité de fibres et en optimisant le mode de fabrication. Le modèle développé décrit explicitement la participation du renfort fibré en traction au niveau local, en enchaînant une phase de comportement écrouissante suivie d’une phase adoucissante. La loi de comportement est fonction de la densité, de l’orientation des fibres vis-à-vis des directions principales de traction, de leur élancement et d’autres paramètres matériaux usuels liés aux fibres, à la matrice cimentaire et à leur interaction. L’orientation des fibres est prise en compte à partir d’une loi de probabilité normale à une ou deux variables permettant de reproduire n’importe quelle orientation obtenue à partir d’un calcul représentatif de la mise en oeuvre du BFUP frais ou renseignée par analyse expérimentale sur prototype. Enfin, le modèle reproduit la fissuration des BFUP sur le principe des modèles de fissures diffuses et tournantes. La loi de comportement est intégrée au sein d’un logiciel de calcul de structure par éléments finis, permettant de l’utiliser comme un outil prédictif de la fiabilité et de la ductilité globale d’éléments en BFUP. Deux campagnes expérimentales ont été effectuées, une à l’Université Laval de Québec et l’autre à l’Ifsttar, Marne-la-Vallée. La première permet de valider la capacité du modèle reproduire le comportement global sous des sollicitations typiques de traction et de flexion dans des éléments structurels simples pour lesquels l’orientation préférentielle des fibres a été renseignée par tomographie. La seconde campagne expérimentale démontre les capacités du modèle dans une démarche d’optimisation, pour la fabrication de plaques nervurées relativement complexes et présentant un intérêt industriel potentiel pour lesquels différentes modalités de fabrication et des BFUP plus ou moins fibrés ont été envisagés. Le contrôle de la répartition et de l’orientation des fibres a été réalisé à partir d’essais mécaniques sur prélèvements. Les prévisions du modèle ont été confrontées au comportement structurel global et à la ductilité mis en évidence expérimentalement. Le modèle a ainsi pu être qualifié vis-à-vis des méthodes analytiques usuelles de l’ingénierie, en prenant en compte la variabilité statistique. Des pistes d’amélioration et de complément de développement ont été identifiées.
