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.

Cumulus momentum fluxes in cloud-resolving model simulations of toga-coare

O objectivo deste trabalho científico é o estudo do transporte vertical de momento linear horizontal (CMT) realizado por sistemas de nuvens de convecção profunda sobre o oceano tropical. Para realizar este estudo, foram utilizadas simulações tridimensionais produzidas por um modelo explícito de nuvens (CRM) para os quatro meses de duração da campanha observacional TOGA COARE que ocorreu sobre as águas quentes do Pacífico ocidental. O estudo foca essencialmente as características estatísticas e à escala da nuvem do CMT durante um episódio de fortes ventos de oeste e durante um período de tempo maior que incluí este evento de convecção profunda. As distribuições verticais e altitude-temporais de campos atmosféricos relacionados com o CMT são avaliadas relativamente aos campos observacionais disponíveis, mostrando um bom acordo com os resultados de estudos anteriores, confirmando assim a boa qualidade das primeiras e fornecendo a confiança necessária para continuar a investigação. A sensibilidade do CMT em relação do domínio espacial do model é analisada, utilizando dois tipos de simulações tridimensionais produzidas por domínios horizontais de diferente dimensão, sugerindo que o CMT não depende da dimensão do domínio espacial horizontal escolhido para simular esta variável. A capacidade da parameterização do comprimento de mistura simular o CMT é testada, destacando as regiões troposféricas onde os fluxos de momento linear horizontal são no sentido do gradiente ou contra o gradiente. Os fluxos no sentido do gradiente apresentam-se relacionados a uma fraca correlação entre os campos atmosféricos que caracterizam esta parameterização, sugerindo que as formulações dos fluxos de massa dentro da nuvem e o fenómeno de arrastamento do ar para dentro da nuvem devem ser revistos. A importância do ar saturado e não saturado para o CMT é estudada com o objectivo de alcançar um melhor entendimento acerca dos mecanismos físicos responsáveis pelo CMT. O ar não saturado e saturado na forma de correntes descendentes contribuem de forma determinante para o CMT e deverão ser considerados em futuras parameterizações do CMT e da convecção em nuvens cumulus. Métodos de agrupamento foram aplicados às contribuições do ar saturado e não saturado, analisando os campos da força de flutuação e da velocidade vertical da partícula de ar, concluindo-se a presença de ondas gravíticas internas como mecanismo responsável pelo ar não saturado. A força do gradiente de pressão dentro da nuvem é também avaliada, utilizando para este efeito a fórmula teórica proposta por Gregory et al. (1997). Uma boa correlação entre esta força e o produto entre efeito de cisalhamento do vento e a perturbação da velocidade vertical é registada, principalmente para as correntes ascendentes dentro da nuvem durante o episódio de convecção profunda. No entanto, o valor ideal para o coeficiente empírico c*, que caracteriza a influência da força do gradiente de pressão dentro da nuvem sobre a variação vertical da velocidade horizontal dentro da nuvem, não é satisfatoriamente alcançado. Bons resultados são alcançados através do teste feito à aproximação do fluxo de massa proposta por Kershaw e Gregory (1997) para o cálculo do CMT total, revelando mais uma vez a importância do ar não saturado para o CMT.

Coupling anchovy eggs and hydrodynamic model as an assessement tool for estuarine ecohydrological management

Nitrate and urban waste water directives have raised the need for a better understanding of coastal systems in European Union. The incorrect application of these directives can lead to important ecological or social penalties. In the paper this problem is addressed to Ria Formosa Coastal Lagoon. Ria Formosa hosts a Natural Park, important ports of the southern Portuguese coast and significant bivalve aquaculture activity. Four major urban waste water treatment plants discharging in the lagoon are considered in this study. Its treatment level must be selected, based on detailed information from a monitoring program and on a good knowledge of the processes determining the fate of the material discharged in the lagoon. In this paper the results of a monitoring program and simulations using a coupled hydrodynamic and water quality / ecological model, MOHID, are used to characterise the system and to understand the processes in Ria Formosa. It is shown that the water residence time in most of the lagoon is quite low, of the order of days, but it can be larger in the upper parts of the channels where land generated water is discharged. The main supply of nutrients to the lagoon comes from the open sea rather than from the urban discharges. For this reason the characteristics and behaviour of the general lagoon contrasts with the behaviour of the upper reaches of the channels where the influence of the waste water treatment plants are high. In this system the bottom mineralization was found to be an important mechanism, and the inclusion of that process in the model was essential to obtain good results.

Disparity energy model with keypoint disparity validation

A biological disparity energy model can estimate local depth information by using a population of V1 complex cells. Instead of applying an analytical model which explicitly involves cell parameters like spatial frequency, orientation, binocular phase and position difference, we developed a model which only involves the cells’ responses, such that disparity can be extracted from a population code, using only a set of previously trained cells with random-dot stereograms of uniform disparity. Despite good results in smooth regions, the model needs complementary processing, notably at depth transitions. We therefore introduce a new model to extract disparity at keypoints such as edge junctions, line endings and points with large curvature. Responses of end-stopped cells serve to detect keypoints, and those of simple cells are used to detect orientations of their underlying line and edge structures. Annotated keypoints are then used in the leftright matching process, with a hierarchical, multi-scale tree structure and a saliency map to segregate disparity. By combining both models we can (re)define depth transitions and regions where the disparity energy model is less accurate.

A disparity energy model improved by line, edge and keypoint correspondences

Disparity energy models (DEMs) estimate local depth information on the basis ofVl complex cells. Our recent DEM (Martins et al, 2011 ISSPlT261-266) employs a population code. Once the population's cells have been trained with randorn-dot stereograms, it is applied at all retinotopic positions in the visual field. Despite producing good results in textured regions, the model needs to be made more precise, especially at depth transitions.

Enterprise architecture model: an approach proposition. A case study of information systems in the hospitality industry

This paper discusses the role of enterprise architecture representation, in the context of ERP (Enterprise Resource Planning) information systems, as an instrument for an organization to reflect on itself and develop its business strategies and respective alignment with Information Systems. The paper proposes a representation model of enterprise architecture, as a tool for recommending good practices, and it emerges from a case study undertaken in the context of and investigation on advantages and limitations of ERP systems in the hospitality industry. The proposed approach is also inspired on other academic or market propositions suitable for the objectives of the investigation. It consists on a set of items representing the steps that must be taken by top managers and IS managers.

Good Practice in EU Public Service Media and Contemporary Practice in Jordan: A Comparative Analysis

UNESCO Amman Office Foreword: UNESCO Amman office is pleased to publish a comparative analysis between good Public Service Media (PSM) practices in Europe and the contemporary practice in Jordan. The study is part of the Support to Media in Jordan project, funded by the European Union, aiming to increase media freedom, media independence and journalistic professionalism in Jordan. The state owned broadcaster, Jordan Radio and Television (JRTV), has informed, entertained and educated Jordanians for decades. JRTV reaches almost every corner of the Kingdom and has the potential to serve all Jordanians with balanced, impartial and accurate news and programmes relevant to their day-to-day lives.Based on this potential there has been a long standing ambition to transform the JRTV from a state broadcaster to a public service broadcaster; from a TV and radio that predominately serves the state, to a broadcaster that serves the public and is independent from the Government of the day. This ambition is expressed also in the Support to Media in Jordan project, agreed between the Government an the EU, under which UNESCO has been asked to produce two studies: The comparative PSM analysis and a broader media landscape assessment based on UNESCO’s Media Development Indicators (MDI’s). The Jordanian MDI assessment was carried out by a team of national and international researchers during the first six months of 2015, and builds on the rich flora of recent studies on the Jordanian media landscape, as well as on original research. The study is available in Arabic and English. Professor Naomi Sakr carried out the comparative PSM analysis parallel to the MDI study, and in close cooperation with the MDI research team and UNESCO Amman office.

Using a cohesive damage model to predict the tensile behaviour of CFRP single-strap repairs

This work addresses both experimental and numerical analyses regarding the tensile behaviour of CFRP single-strap repairs. Two fundamental geometrical parameters were studied: overlap length and patch thickness. The numerical model used ABAQUS® software and a developed cohesive mixed-mode damage model adequate for ductile adhesives, and implemented within interface finite elements. Stress analyses and strength predictions were carried out. Experimental and numerical comparisons were performed on failure modes, failure load and equivalent stiffness of the repair. Good correlation was found between experimental and numerical results, showing that the proposed model can be successfully applied to bonded joints or repairs.

Bertrand model under incomplete information

We consider a Bertrand duopoly model with unknown costs. The firms' aim is to choose the price of its product according to the well-known concept of Bayesian Nash equilibrium. The chooses are made simultaneously by both firms. In this paper, we suppose that each firm has two different technologies, and uses one of them according to a certain probability distribution. The use of either one or the other technology affects the unitary production cost. We show that this game has exactly one Bayesian Nash equilibrium. We analyse the advantages, for firms and for consumers, of using the technology with highest production cost versus the one with cheapest production cost. We prove that the expected profit of each firm increases with the variance of its production costs. We also show that the expected price of each good increases with both expected production costs, being the effect of the expected production costs of the rival dominated by the effect of the own expected production costs.

International Stackelberg model with tariffs

This paper analyses the effects of tariffs on an international economy with a monopolistic sector with two firms, located in two countries, each one producing a homogeneous good for both home consumption and export to the other identical country. We consider a game among governments and firms. First, the government imposes a tariff on imports and then we consider the two types of moving: simultaneous (Cournot-type model) and sequential (Stackelberg-type model) decisions by the firms. We also compare the results obtained in each model.

Data analysis applied to the evaluation of a technological nature teaching model as a regional development tool

This paper presents the creation and development of technological schools directly linked to the business community and to higher public education. Establishing themselves as the key interface between the two sectors they make a signigicant contribution by having a greater competitive edge when faced with increasing competition in the tradional markets. The development of new business strategies supported by references of excellence, quality and competitiveness also provides a good link between the estalishment of partnerships aiming at the qualification of education boards at a medium level between the technological school and higher education with a technological foundation. We present a case study as an example depicting the success of Escola Tecnológica de Vale de Cambra.

Mathematical model for HIV dynamics in HIV-specific helper cells

In this paper we study a delay mathematical model for the dynamics of HIV in HIV-specific CD4 + T helper cells. We modify the model presented by Roy and Wodarz in 2012, where the HIV dynamics is studied, considering a single CD4 + T cell population. Non-specific helper cells are included as alternative target cell population, to account for macrophages and dendritic cells. In this paper, we include two types of delay: (1) a latent period between the time target cells are contacted by the virus particles and the time the virions enter the cells and; (2) virus production period for new virions to be produced within and released from the infected cells. We compute the reproduction number of the model, R0, and the local stability of the disease free equilibrium and of the endemic equilibrium. We find that for values of R0<1, the model approaches asymptotically the disease free equilibrium. For values of R0>1, the model approximates asymptotically the endemic equilibrium. We observe numerically the phenomenon of backward bifurcation for values of R0⪅1. This statement will be proved in future work. We also vary the values of the latent period and the production period of infected cells and free virus. We conclude that increasing these values translates in a decrease of the reproduction number. Thus, a good strategy to control the HIV virus should focus on drugs to prolong the latent period and/or slow down the virus production. These results suggest that the model is mathematically and epidemiologically well-posed.
