The move from cash to accruals accounting by many governments is viewed as an aspect of an ongoing New Public Management agenda designed to achieve a more business-like and performance-focused public sector. Proponents argue that accruals accounting provides more appropriate information for decision makers and ultimately leads to a more efficient and effective public sector. The transition from cash to accruals accounting for UK central government departments was announced in the early 1990s and was embedded within approximately ten years. At that time there were clear indications that analogous changes, following a similar timeline, would occur in the Republic of Ireland (RoI). In reality, the changes were significantly less extensive. Utilising document analysis and interviews with key actors, this paper considers why a functioning accruals system was established in the UK whereas in the RoI the change to accruals accounting was a ‘road not taken’.

A single layer, frequency selective surface based, sub-millimeter wave transmission polarizer is presented that converts incident slant linear 45° polarization into circular polarization upon transmission. The polarization convertor consists of a 30 mm diameter 10 thick silicon reinforced metalized screen containing 2700 resonator cells and perforated with nested split ring slot apertures. The screen was designed and optimized using CST Microwave Studio and predictions were validated experimentally by transmission measurements over the 250-365 GHz frequency range. This frequency range is used for remote environmental monitoring and 325 GHz represents a molecular emission line for H2O. The results obtained show good agreement between measured and modeled predictions. The measured 3 dB axial ratio bandwidth was 11.75%, measured minimum Axial Ratio was 0.19 dB and the measured insertion loss of the single layer screen was 3.38 dB

The EU’s Peace programmes in Ireland have promoted the cross-border activity of Third sector groups. Potentially, such activity gives substantive meaning to regional cross-border governance and helps to ameliorate ethno-national conflict by providing positive sum outcomes for ‘post-conflict’ communities. The paper mobilizes focused research conducted by the authors to explore this potential. It finds that while regional cross-border governance has indeed developed under the Peace programmes, the sustainability of the social partnerships underpinning this governance is uncertain and its significance for conflict resolution is qualified by difficulties in forming a stable power-sharing arrangement at the political elite level.

This paper examines the impact of minimum wages on earnings and employment in selected branches of the retail-trade sector, 1990-2005, using county-level data on employment and a panel regression framework that allows for county-specific trends in sectoral outcomes. We focus on specific subsectors within retail trade that are identified as particularly low-wage. We find little evidence of disemployment effects once we allow for geographic-specific trends. Indeed, in many sectors the evidence points to modest (but robust) positive employment effects. (C) 2009 Elsevier B.V. All rights reserved.

Accounting in the UK charity sector has changed massively over the last 25 years, with various stakeholders influencing what has occurred. Using insights from stakeholder theory, and interviews with a number of key actors, this article focuses on the influence of one definitive stakeholder – government – in developing a regime of quality accounting and reporting in the sector. In particular, the evolution of the Statement of Recommended Practice for charities is explored. It is argued that a much tighter and more meaningful regime of accounting and reporting has been encouraged by government, amongst other stakeholders, and this has led to a more accountable and healthier charitable sector.
