The Promise of Peace:Revisiting the Northern Irish Model

The Northern Ireland peace process is often eulogized as a successful model of conflict transformation. Although the process exhibited many of the problems that beset other societies seeking to move from conflict to a negotiated peace (including disagreements over the functioning of institutions and the meanings of cultural symbols, unresolved issues relating to the effects of political violence on victims and survivors and society at large; and the residual presence of violent and political ‘spoiler’ groups), the resilience of political dialogue has proven remarkable.
This collection revisits the promise of ‘a truly historic opportunity for a new beginning’ a decade and a half on from the signing of the Belfast/Good Friday Agreement in 1998. The book will bring together academics from across a number of disciplines, including management and organizational behaviour, law, politics, sociology, archaeology and literature.

The different contributions aim to assess what impact it has made in the legal, policy, and institutional areas it specifically targeted: political reform, human rights and equality provision, working through legacies of the past (including police reform, prisoner release and victims' rights) and the building of new relationships within the island of Ireland and between Ireland and Britain. With the emergence of first-time voters who had no direct experience of the violence the book explores what the Agreement offers for future generations.

The book is the culmination of a 12-month research project sponsored by the British Academy and Leverhulme that addressed the following aspects of the peace process:
Peace walls: The euphemistically named peace walls remain one of the most visible reminders of Northern Ireland’s divisions and they are famously the only material manifestations of the conflict that have grown in number and extent since the 1998 Agreement. They were originally placed between antagonistic neighbouring communities – often at their request – at times of heightened tensions. Research under this theme explored the lack of ongoing engagement with their continuing presences, evolving meanings and impact on the communities that reside beside them needs to be overtly addressed.
Cultural division: Cultural differences have often been seen as lying at the heart of the ‘Irish problem’. Despite this, art and artists have increasingly been seen as having the potential to develop new discourses. Research explored the following questions: What role can the arts play in re-imagining the spaces opened up by the promises of the 1998 Agreement? What implication does the confrontation with the legacies of conflict have for artistic practices? What impact do the arts have on constructions of identity, on narratives of history, and on electoral politics?
Institutional transformation: This strand of research explored the significance of the process of organizational change which followed the establishment of the 1998 on political and other public policy institutions such as the police and prison services. It suggested that the experience and lessons learned from such periods of transition have much to contribute to how Northern Ireland begins to address political polarization in other areas of public service infrastructure, chiefly around the sectarian monoliths of education and housing.
Working through the past: ‘Legacy’ issues have gained increasing prominence since 1998: issues to do with public symbolism (particularly relating to the flying of flags and parading), defining victimhood, securing victims’ rights, recovery of the ‘disappeared’, reintegrating ex- prisoners back into society, and the possibilities for truth recovery and reconciliation have all acquired salient and emotive force. Although the 1998 Agreement promised to ‘honour the dead’ through a ‘new beginning’, it is increasingly unclear as to whether an agreed narrative about the past is possible – or even worthwhile pursuing. Research under this theme looked at the complex relationship between memory, commemoration and violence; how commemorative events are performed, organized, policed and represented. It also addressed the fraught issue of how to come to terms with Northern Ireland’s divided and bloodied past.

The editors are in the process of guiding contributors to adapt their papers, which were presented to a series of workshops on the above themes, to the purposes of the book. In particular, the contributors will be guided to focus on the related aims of assessing the extent of change that has occurred and providing an assessment of what remains to be done. To that end, contributors are asked to engage directly with the questions that close the ‘Introduction’, namely: To what extent has the ‘promise’ of the 1998 Agreement been fulfilled? To what extent has the 1998 Agreement given rise to forms of exclusion? To what extent has the 1998 Agreement shaped new forms of debate, dispute and engagement? In the absence of that guidance having been sent out yet, the outlines below are, for the time being, the abstracts of their original papers.

A imagem dos destinos turísticos de montanha: olhares dos residentes e dos turistas

No actual contexto de competitividade, os destinos turísticos podem diferenciar-se pela imagem que os turistas e residentes têm sobre eles enquanto espaços alternativos de lazer e turismo (Baloglu & Mangaloglu, 2001). A imagem dos destinos constitui um conceito central na literatura em turismo porque está fortemente relacionada com o comportamento dos residentes e dos turistas (Baloglu & McCleary, 1999). A imagem afecta o comportamento de escolha e avaliação do destino, da viagem e da participação e experiência turísticas (Echtner and Ritchie 1991; Lee & Lee, 2009). Por outro lado, os residentes têm, também eles, uma imagem sobre o local onde residem que pode e deve ser analisada, afectando, por sua vez, a percepção que os turistas têm desses espaços (Gallarza, Saura & García, 2001). Alguns destinos turísticos possuem características simbólicas que exercem forte influência na formação da sua imagem, como são o caso dos espaços de montanha. De facto, as montanhas constituem um dos mais profundos arquétipos da Humanidade simbolizando poder, liberdade e eternidade (Smethurst, 2000, p.36). As regiões de montanha têm-se tornado num dos mais atractivos destinos turísticos constituindo a sua procura, actualmente, 20% dos fluxos turísticos globais com 500 milhões de turistas anualmente (UNEP, 2002; Thomas et al., 2006). Mas até muito recentemente, os estudos sobre os espaços de montanha limitavam-se, maioritariamente, às suas características físicas, ecológicas e ambientais (Smethurst, 2000). Uma abordagem do ponto de vista do turismo de montanha, no contexto da imagem, pode revelar-se, assim, essencial. Neste contexto, o presente estudo pretende analisar, de uma forma holística e multidisciplinar, a imagem que os residentes e turistas têm dos espaços de montanha, bem como o respectivo gap. O objectivo central é construir uma escala MDI - Mountain Destination Image Scale - no sentido de medir os parâmetros da imagem do destino, incluindo factores cognitivos e afectivos e tendo em conta os grupos populacionais turistas e residentes. Com base numa extensa revisão da literatura em imagem dos destinos turísticos e nos significados sociais e culturais da montanha ao longo do tempo, e no âmbito do trabalho empírico realizado a 315 turistas e 315 residentes na Serra da Estrela (Portugal), Alpes (França, Áustria e Suiça) e Picos da Europa (Espanha), os resultados indicam que a escala multidimensional MDI integra cinco dimensões de imagem de montanha pelos turistas: (1) histórico-cultural, (2) natural/ecológica, (3) social e prestígio, (4) lazer e desporto e (5) afectiva; e três dimensões percepcionadas pelos residentes: (1) mística/sagrada, (2) histórico-cultural e (3) afectiva. A discussão é centrada nas implicações teóricas e práticas da escala MDI no planeamento, gestão e marketing dos destinos turísticos de montanha. São igualmente apresentadas as limitações do presente estudo e traçadas algumas linhas orientadoras para investigações futuras.

Sources, signification and genre stability in American Film Noir

O conceito film noir é manifestamente complexo de ser definido. Atendendo a que não existe um estudo verdadeiramente completo sobre a estilística do film noir, esta tese, inserida no âmbito dos Estudos Cinematográficos, pretende ser uma tentativa de exploração do conceito film noir e do género cinematográfico sob vários aspectos. Trata-se, no fundo, de uma forma de restabelecer este conceito descritivo americano, desde o início dos anos quarenta até finais dos cinquenta, através de um processo de análise iconográfica. Este projecto focaliza-se na seguinte questão de investigação: pode o film noir americano ser considerado um género cinematográfico enquanto tal? Numa primeira fase, analisam-se os contextos cinematográfico e social preexistentes no cinema noir de modo a compreender este fenómeno cinematográfico, enquanto uma extensão do movimento hard-boiled, uma cosmovisão subversiva que descaradamente se opõe aos mitos americanos da auto-promoção americana, que marcaram muitos filmes de Hollywood durante a época da Depressão. Depois, descrevem-se os movimentos culturais específicos, bem como os acontecimentos sociopolíticos da época, a psicanálise, o estruturalismo e a teoria de autor, que ajudaram a contextualizar os padrões do film noir e a forma como o conceito acabou por gradualmente penetrar na cultura americana. As películas a analisar concentrar-se-ão sobre símbolos visuais específicos e elementos cinematográficos (tais como os das técnicas de iluminação e fotografia), adoptando uma perspectiva semiótica. Através dos conceitos saussuriano de “signo” e de “ícone” perceiano, procuro demonstrar de que forma os símbolos em filmes noir constituem significados que são enfaticamente indexicais, isto é, de que maneira eles são transversais, passando de um símbolo para outro (ou evento), direccionando e coagindo a atenção do espectador. A tese conclui então que o filme noir não pode ser considerado e entendido como um género fílmico e que o seu estilo visual (o aspecto dominante do cinema noir) tem como propósito acentuar o desencanto sentido no rescaldo da guerra, representar os meandros da vida urbana americana e, principalmente, enfatizar a incerteza, a ansiedade e o lado obscuro da existência humana.

Regularity of Wiener-Hopf plus Hankel operators

In this thesis we consider Wiener-Hopf-Hankel operators with Fourier symbols in the class of almost periodic, semi-almost periodic and piecewise almost periodic functions. In the first place, we consider Wiener-Hopf-Hankel operators acting between L2 Lebesgue spaces with possibly different Fourier matrix symbols in the Wiener-Hopf and in the Hankel operators. In the second place, we consider these operators with equal Fourier symbols and acting between weighted Lebesgue spaces Lp(R;w), where 1 < p < 1 and w belongs to a subclass of Muckenhoupt weights. In addition, singular integral operators with Carleman shift and almost periodic coefficients are also object of study. The main purpose of this thesis is to obtain regularity properties characterizations of those classes of operators. By regularity properties we mean those that depend on the kernel and cokernel of the operator. The main techniques used are the equivalence relations between operators and the factorization theory. An invertibility characterization for the Wiener-Hopf-Hankel operators with symbols belonging to the Wiener subclass of almost periodic functions APW is obtained, assuming that a particular matrix function admits a numerical range bounded away from zero and based on the values of a certain mean motion. For Wiener-Hopf-Hankel operators acting between L2-spaces and with possibly different AP symbols, criteria for the semi-Fredholm property and for one-sided and both-sided invertibility are obtained and the inverses for all possible cases are exhibited. For such results, a new type of AP factorization is introduced. Singular integral operators with Carleman shift and scalar almost periodic coefficients are also studied. Considering an auxiliar and simpler operator, and using appropriate factorizations, the dimensions of the kernels and cokernels of those operators are obtained. For Wiener-Hopf-Hankel operators with (possibly different) SAP and PAP matrix symbols and acting between L2-spaces, criteria for the Fredholm property are presented as well as the sum of the Fredholm indices of the Wiener-Hopf plus Hankel and Wiener-Hopf minus Hankel operators. By studying dependencies between different matrix Fourier symbols of Wiener-Hopf plus Hankel operators acting between L2-spaces, results about the kernel and cokernel of those operators are derived. For Wiener-Hopf-Hankel operators acting between weighted Lebesgue spaces, Lp(R;w), a study is made considering equal scalar Fourier symbols in the Wiener-Hopf and in the Hankel operators and belonging to the classes of APp;w, SAPp;w and PAPp;w. It is obtained an invertibility characterization for Wiener-Hopf plus Hankel operators with APp;w symbols. In the cases for which the Fourier symbols of the operators belong to SAPp;w and PAPp;w, it is obtained semi-Fredholm criteria for Wiener-Hopf-Hankel operators as well as formulas for the Fredholm indices of those operators.

Design e avaliação de pictogramas farmacêuticos

A informação inerente aos medicamentos no processo de medicação e prescrição tem revelado insuficiências relativamente às necessidades do utilizador. Este projecto aborda essas dificuldades e procura contribuir, através do design e avaliação de pictogramas farmacêuticos, para um melhor acesso das pessoas à informação, oral e escrita, prestada por médicos, farmacêuticos e pela literatura inclusa dos medicamentos. Verificámos que, nos últimos 40 anos, se desenvolveram quase mil representações gráficas, provenientes de 20 países, sobre mensagens relativas a perigos, precauções e informações de como tomar o medicamento. Com base nesse conjunto mundial colectado, tão alargado e diversificado, procedeu-se à analise, agrupamento e comparação dessas representações com vista a apurar a diversidade gráfica e escrita das 75 mensagens farmacêuticas identificadas nesta investigação. Foi seguidamente consultada uma centena de profissionais de saúde dentro da área farmacêutica para selecção e definição da informação a ser projectada em pictogramas. Algumas das mensagens seleccionadas foram, por ordem de importância: “Não aplicar nos olhos”, “Não beber álcool enquanto estiver a tomar o medicamento” e “Guardar no frigorífico”. Foi concebido um sistema PictoPharma, bilingue (Português e Inglês), composto por 32 pictogramas farmacêuticos, com várias possibilidades cromáticas de acordo com as diversas aplicações para suportes de impressão e ecrã (Registo de Propriedade Industrial – marca e design). Embora o sistema projectado possa aumentar a capacidade de recordar as informações importantes pelas pessoas em geral, os públicos-alvo que mais beneficiarão com o sistema são: pessoas que apresentam especiais dificuldades de leitura - analfabetos, pessoas com nenhum conhecimento ou um conhecimento limitado da língua; pessoas com dificuldades para relembrar e / ou compreender o tratamento - população envelhecida, sob múltiplos tratamentos ou com menores capacidades intelectuais; pessoas que não falam a língua local ou são de uma cultura diferente - estrangeiros, turistas, imigrantes. Foram feitos testes de usabilidade com os públicos-alvo específicos, de forma a verificar a percentagem de compreensão dos pictogramas, sem a respectiva legenda e de acordo com as normas internacionais de normalização. Os resultados dos testes indicaram que metade do sistema atingiu os 100% de compreensão e a outra metade atingiu mais de 88%. O sistema PictoPharma criado caracteriza-se: pelo design gráfico no seu contraste visual e na possibilidade de leitura numa escala reduzida; pelo conceito de familiaridade gráfica representada no seu conjunto, de forma a tornar os pictogramas mais facilmente memorizáveis; pelo estudo feito para minimizar especificidades culturais visuais; pelas diversas aplicações possíveis na indústria; pelas direcções que aponta para futuras investigações sobre as escolhas visuais culturais inerentes a um projecto de design com este.

Grounding human vocabulary in robot perception through interaction

This thesis addresses the problem of word learning in computational agents. The motivation behind this work lies in the need to support language-based communication between service robots and their human users, as well as grounded reasoning using symbols relevant for the assigned tasks. The research focuses on the problem of grounding human vocabulary in robotic agent’s sensori-motor perception. Words have to be grounded in bodily experiences, which emphasizes the role of appropriate embodiments. On the other hand, language is a cultural product created and acquired through social interactions. This emphasizes the role of society as a source of linguistic input. Taking these aspects into account, an experimental scenario is set up where a human instructor teaches a robotic agent the names of the objects present in a visually shared environment. The agent grounds the names of these objects in visual perception. Word learning is an open-ended problem. Therefore, the learning architecture of the agent will have to be able to acquire words and categories in an openended manner. In this work, four learning architectures were designed that can be used by robotic agents for long-term and open-ended word and category acquisition. The learning methods used in these architectures are designed for incrementally scaling-up to larger sets of words and categories. A novel experimental evaluation methodology, that takes into account the openended nature of word learning, is proposed and applied. This methodology is based on the realization that a robot’s vocabulary will be limited by its discriminatory capacity which, in turn, depends on its sensors and perceptual capabilities. An extensive set of systematic experiments, in multiple experimental settings, was carried out to thoroughly evaluate the described learning approaches. The results indicate that all approaches were able to incrementally acquire new words and categories. Although some of the approaches could not scale-up to larger vocabularies, one approach was shown to learn up to 293 categories, with potential for learning many more.

An embodied approach to language: the role of bodily feedback in discourse processing

Theories of embodied cognition argue that language processing arises not from amodal symbols that redescribe sensorimotor and affective experiences, but from partial simulations (reenactments) of modality-specific states. Recent findings on processing of words and sentences support such a stance emphasizing that the role of the body in the domain of language comprehension should not be overlooked or dismissed. The present research was conducted to extend prior work in two important ways. First, the role of simulation was tested with connected discourse rather than words or sentences presented in isolation. Second, both “online” and “offline” measures of discourse comprehension were taken. In Experiments 1 and 2 participants’ facial postures were manipulated to show that preparing the body for processing of emotion-congruent information improves discourse comprehension. In Experiment 3 the direction of body posture was manipulated to show that implicit properties of simulations, such as spatial dimension or location, are at least somewhat involved in processing of large language segments such as discourse. Finally, in Experiments 4 and 5 participants’ body movement and body posture were manipulated to show that even understanding of language describing metaphorical actions physically impossible to perform involves constructing a sensorimotor simulation of the described event. The major result was that compatibility between embodiment and language strongly modulated performance effectiveness in experiments on simulation of emotion and metaphorical action. The effect of simulation on comprehension of discourse implying spatial dimension was fragile. These findings support an embodied simulation account of cognition suggesting that sensorimotor and affective states are at least partially implicated in “online” and “offline” discourse comprehension.

Readjusting our Sporting Sites/Sight: Sportification and the Theatricality of Social Life

This paper points out the potential of using sport for the analysis of society. Cultivated human movement is a specific social and cultural subsystem (involving sport, movement culture and physical culture), yet it becomes a part of wider social discourses by extending some of its characteristics into various other spheres. This process, theorised as sportification, provides as useful concept to examine the permeation of certain phenomena from the area of sport into the social reality outside of sport. In this paper, we investigate the phenomena of sportification which we parallel with visual culture and spectatorship practices in the Renaissance era. The emphasis in our investigation is on theatricality and performativity; particularly, the superficial spectator engagement with modern sport and sporting spectacles. Unlike the significance afforded to visualisation and deeper symbolic interpretation in Renaissance art, contemporary cultural shifts have changed and challenged the ways in which the active and interacting body is positioned, politicised, symbolised and ultimately understood. We suggest here that the ways in which we view sport and sporting bodies within a (post)modern context (particularly with the confounding amalgamations of signs and symbols and emphasis on hyper-realities) has invariably become detached from sports’ profound metaphysical meanings and resonance. Subsequently, by emphasising the associations between social theatrics and the sporting complex, this paper aims to remind readers of ways that sport—as a nuanced phenomenon—can be operationalised to help us to contemplate questions about nature, society, ourselves and the complex worlds in which we live.
