Identifying rent pressures [on housing market] in your neighbourhood: a new model of Irish regional rent indicators. ESRI WP567, June 2017
Since 2013, researchers in the Economic and Social Research Institute (ESRI)
have compiled a hedonic rental index for the Residential Tenancies Board (RTB). The
indicator estimates a standardised rental index on a national, Dublin and outside of Dublin
basis based on the 950,000 rental properties registered with the RTB. The provision in late
2016 of detailed geographical identifiers has enabled an alternative series of indicators to
be estimated. In particular, hedonic rental indicators for 137 local electoral areas (LEAs)
are now available on a quarterly basis from 2007 quarter 3 to 2016 quarter 4. By providing
a more accurate assessment of regional trends in rental supply and demand, the indicators
should enable a more precise implementation of policies in the rental market. They should
also serve as a proxy for measuring underlying economic activity in these regions on an
ongoing basis
Striving to Practice What We Preach: Academics reflecting on teaching reflective practice
That reflection is part of the HRD academics’ continuing professional development is a powerful rhetoric. But to what extent are we guilty of hypocrisy? Inspired by the title and theme of the conference ‘HRD: Reflecting upon the Past, Shaping the Future’ this paper seeks to make a critically reflective statement on our own practice as HRD academics teaching and researching reflective practice. Researching ‘practising what we preach’, in the context of reflective practice, raises difficult questions but offers the potential for valuable insight into the HRD academics’ professional practice
Oxidation mechanism in metal nanoclusters: Zn nanoclusters to ZnO hollow nanoclusters
Zn nanoclusters (NCs) are deposited by Low-energy cluster beam deposition
technique. The mechanism of oxidation is studied by analysing their
compositional and morphological evolution over a long span of time (three
years) due to exposure to ambient atmosphere. It is concluded that the
mechanism proceeds in two steps. In the first step, the shell of ZnO forms over
Zn NCs rapidly up to certain limiting thickness: with in few days -- depending
upon the size -- Zn NCs are converted to Zn-ZnO (core-shell), Zn-void-ZnO, or
hollow ZnO type NCs. Bigger than ~15 nm become Zn-ZnO (core-shell) type: among
them, NCs above ~25 nm could able to retain their initial geometrical shapes
(namely triangular, hexagonal, rectangular and rhombohedral), but ~25 to 15 nm
size NCs become irregular or distorted geometrical shapes. NCs between ~15 to 5
nm become Zn-void-ZnO type, and smaller than ~5 nm become ZnO hollow sphere
type i.e. ZnO hollow NCs. In the second step, all Zn-void-ZnO and Zn-ZnO
(core-shell) structures are converted to hollow ZnO NCs in a slow and gradual
process, and the mechanism of conversion proceeds through expansion in size by
incorporating ZnO monomers inside the shell. The observed oxidation behaviour
of NCs is compared with theory of Cabrera - Mott on low-temperature oxidation
of metal.Comment: 9 pages, 8 figure
