Light and darkness in an Edwardian insitution for the insane poor - illuminating the material practices of the Asylum Age

Natural light and its provision within asylum and other buildings is a neglected aspect of the historical archaeology of institutions. An Edwardian asylum in the north of Ireland is analysed for the management of natural light through the siting of buildings, window design and placement of interior glazing. A close reading of selected contemporary literature relating to natural light is employed to assess the significance of light provision within institutions of this period and contemporary discourses are in turn illuminated by the material practices recorded in the case study.

Experimental measurements of the collisional absorption of XUV radiation in warm dense aluminium

The collisional (or free-free) absorption of soft x rays in warm dense aluminium remains an unsolved problem. Competing descriptions of the process exist, two of which we compare to our experimental data here. One of these is based on a weak scattering model, another uses a corrected classical approach. These two models show distinctly different behaviors with temperature. Here we describe experimental evidence for the absorption of 26-eV photons in solid density warm aluminium (Te≈1 eV). Radiative x-ray heating from palladium-coated CH foils was used to create the warm dense aluminium samples and a laser-driven high-harmonic beam from an argon gas jet provided the probe. The results indicate little or no change in absorption upon heating. This behavior is in agreement with the prediction of the corrected classical approach, although there is not agreement in absolute absorption value. Verifying the correct absorption mechanism is decisive in providing a better understanding of the complex behavior of the warm dense state.

The Un-Politics of New Public Management in Ireland

Many of the principles and indeed the rhetoric of New Public Management proved attractive to both politicians and senior bureaucrats across the developed world as a remedy for problems in policy processes. Ireland shares many features of its constitutional structures and political practices with Britain, Canada, Australia, New Zealand, all of them early and enthusiastic adopters of NPM. Some of the organizational and procedural changes in Irish public administration do indeed bear similarities to those we would expect to see as a result of adopting principles of NPM. However, we contend that surface impressions are misleading. Drawing on a time-series database of Irish state institutions, we show that organizational changes were not necessarily driven by NPM. The absence of strong political drivers meant that reform initiatives did not fundamentally alter the configuration of the Irish public administration. Many of the problems that NPM was intended to address are only now coming under scrutiny.
