Spatial Mobility Intentions, the Labour Market and Incapacity Benefit Claimants Evidence from Northern Ireland

The paper analyses the work-related spatial mobility intentions of incapacity benefit (IB) claimants in Northern Ireland using a new survey dataset. Greater understanding of the prospective mobility of benefit claimants contributes to debates about employability, inclusion in the labour market and arguments about spatial mismatch. The analysis finds that IB claimants are not markedly less mobile than other population groups; that mobility is shaped by age, level of qualification, illness type, ability to drive and motivation; and that geography is important in several ways. The paper concludes by arguing that limited spatial mobility is a good indicator of disadvantage and that spatial mobility should be placed nearer the centre of the design and delivery of labour market policy

On the mobility of a one-dimensional damped Frenkel-Kontorova chain: Commensurate versus incommensurate

The mobility of a one-dimensional damped Frenkel-Kontorova chain under a de driving force is studied numerically and analytically For the commensurate case, the particles in the chain me synchronized st high driving force. For the incommensurate chain, a single mode solution dominates st high mobility regime. We are able to calculate the mobilities for both the cases analytically, and a good agreement with numerical results is found. The mobility hysteresis for the incommensurate chain is explained by the existence of two branches of physical solutions, and transitions occur when one of them breaks up.

Intelligent demand response electric water heating to integrate wind power in Ireland

Dwindling fossil fuel resources and pressures to reduce greenhouse gas (GHG) emissions will result in a more diverse range of generation portfolios for future electricity systems. Irrespective of the portfolio mix the overarching requirement for all electricity suppliers and system operators is that supply instantaneously meets demand and that robust operating standards are maintained to ensure a consistent supply of high quality electricity to end-users. Therefore all electricity market participants will ultimately need to use a variety of tools to balance the power system. Thus the role of demand side management (DSM) with energy storage will be paramount to integrate future diverse generation portfolios. Electric water heating (EWH) has been studied previously, particularly at the domestic level to provide load control, peak shave and to benefit end-users financially with lower bills, particularly in vertically integrated monopolies. In this paper, a continuous Direct Load Control (DLC) EWH algorithm is applied in a liberalized market environment using actual historical electricity system and market data to examine the potential energy savings, cost reductions and electricity system operational improvements.
