Introduction
Since the 1980s there have been major policies and projects for the redevelopment of Dublin Docklands. These projects were mainly aimed at profitable development of office, commercial and residential space, without a sound plan that would preserve the identity or community of the area. The recent shift in policies and urban design principles in the Dublin Docklands Area Master Plan 2008 shows that policy makers have acknowledged that mistakes were made in the last decades of the 20th century. The current map of the Dublin Docklands Area Master Plan 2008 gives us useful information about these changes. The Ringsend/ Irishtown area, which has kept a great part of its urban form and community identity throughout centuries, is described as an ‘area of protection of residential and services amenities’ (DDDA, 2008, map A). Meanwhile, the area of the Grand Canal Docks, recently developed, is described with the objective ‘to seek the social, economic and physical development or rejuvenation
within an area of mixed use of which residential and enterprise facilities would be the predominant uses’ (DDDA, 2008, map A). This classification shows that recent development has been unable to achieve the cohesion and complexity of existing neighbourhoods, revealing flaws not only in policy, but also in the built environment and approaches to urban design.
The shift towards the consideration of more community participation reveals a need to understand the tradition and past of these communities, while the urban fabric of small plots in the existing neighbourhoods, therefore, seems to have a very important role in the conservation of identity of place and providing the opportunity for difference within regularity. On the other hand, the new fabric of residential block developments in the docklands denies the possibility of developing a sense of community, and by providing only regularity, does not leave space for difference.
This paper will address questions related to urban morphology and town analysis in the case of Ringsend and Irishtown. This will provide a tool to learn from the past and perhaps find new models of development that might be less detrimental for the heritage of cities and urban communities. One of the ideas of this paper is to adhere to the new tendency in conservation policies to provide a broader analysis of urban areas, not only considering individual monuments in cities, but also analysing the significance of urban morphology and intangible heritage. It forms part of an OPW Post- Doctoral Fellowship in Conservation Studies and Environmental History.1 Research has been carried out in different areas of urban history of Dublin’s southern waterfront, including infrastructure history and a thorough analysis of the letters of the Pembroke Estate of the 19th century, which included the areas of Ringsend and Irishtown. However, this paper focuses on the study of urban form of the area and its significance to Dublin’s heritage.

Laser driven proton beams have been used to diagnose transient fields and density perturbations in laser produced plasmas. Grid deflectometry techniques have been applied to proton radiography to obtain precise measurements of proton beam angles caused by electromagnetic fields in laser produced plasmas. Application of proton radiography to laser driven implosions has demonstrated that density conditions in compressed media can be diagnosed with million electron volt protons. This data has shown that proton radiography can provide unique insight into transient electromagnetic fields in super critical density plasmas and provide a density perturbation diagnostics in compressed matter.

Rising levels of urban deprivation and a perception that poverty has become more concentrated in such areas and has taken on a qualitatively different character have provoked a variety of popular and academic responses. The potentially most fruitful set of hypotheses focuses on the unintended of weak labour force attachment and social isolation is perceived to lead to behaviour and orientations that contribute to a vicious circle of deprivation. In examining the value of this conceptual framework in the Irish case we proceed by measuring directly the social-psychological factors which ave hypothesized to mediate the 'underclass' process.
A significantly higher level of poverty is found in urban public-sector tenant households. This finding cannot be accounted for entirely by socio-demographic differences. It is the assessment of this net or residual effect that is crucial to an evaluation of vicious circle explanations. Controlling for the critical social-psychological factors we found that net effect was reduced by less than a quarter and concluded that the remaining effect is more plausibly attributed to the role of selection than to underclass processes. Analysis of the changing relationship between urban public-sector tenancy and poverty provides support for this interpretation.
For the main part the distinctiveness of social housing tenants is a consequence of the disadvantages they stiffer in relation to employment opportunities and living standards. Ultimately it is these problems that policy interventions, whatever the level at which they take place, must address.
