The objective of the article is to examine the way in which social work in Ireland evolved from practices of philanthropy in the late 19th century to a distinct professional strategy in the present. Results: The results of archival research show that philanthropy in Ireland was provided almost exclusively by religious organizations and was constructed within a discourse of sectarianism and rivalry between the two main denominations, Catholic and Protestant, up to the 1960s. It is only in the past 30 years that social work has become firmly established as a secular strategy. Conclusions: It is concluded that although social work is now clearly distinct from voluntary and religious-based social work practices, some of its present principles and practices remain continuous with its historical antecedents.

The aim of this article is respond to some of the issues addressed by Powell (1998). It focuses on his consideration of the role and task of social work within a changing society. I argue that, before postulations about the future role of social work in Ireland can be made, consideration of its current nature and the form of its discourses are necessary. I then go on to critique Powell's analysis of social work in the context of concepts such as empowerment, participation and prevention and argue that, by failing to consider the necessarily regulatory and centralized nature of much of Irish social work currently, such an analysis remains merely rhetorical. Powell's reference to the Irish Association of Social Workers' Code of Ethics (1995) as evidence of social work entering a period of reflexive modernity is also examined. The article concludes with a call for a move away from utopian speculation within Irish social work discourse towards a more realistic and constructive analysis of both the future potential and the limitations of Irish social work, given its spatial and discursive constraints.

For many decades it has been assumed that an adsorbate centered above a metal surface and with a net negative charge should increase the work function of the surface. However, despite their electronegativity, N adatoms on W{100} cause a significant work function decrease. Here we present a resolution of this anomaly. Using density functional theory, we demonstrate that while the N atom carries a negative charge, of overriding importance is a reduction in the surface overspill electron density into the vacuum, when that charge is engaged in bonding to the adatom. This novel interpretation is fundamentally important in the general understanding of work function changes induced by atomic adsorbates.
