In this paper, we provide alternative measures of the brain drain by defining skilled immigrants as those arrived in the receiving country after age 12, 18 or 22. We use data on age of entry collected in a sample of OECD countries and then estimate the age-of-entry structure in the remaining host countries. The corrected brain drain rates are obviously below the global rates calculated in Docquier and Marfouk (2006). 1 [less ▲]

Although signal transducer and activator of transcription 1 (STAT1) mediated regulation of p53 transcription and apoptosis has been previously reported, modulation of other members of the p53 family of transcription factors remains poorly understood. In this study, we found that STAT1 and TA-p73 can interact directly and that p73-mediated Bax promoter activity was observed to be reduced by STAT1 expression in a p53-independent manner for which STAT1 Tyrosine-701 and Serine-727 are key residues. This study presents the first report physically linking STAT1 and TA-p73 signalling and highlights the modulation of the Bax promoter in the context of IFN-gamma stimulation. [less ▲]

This research report discusses the workplace-based methodological design and selected findings of my PhD research on the attitudes and behaviours of non-Māori New Zealanders towards the Māori language. A participant recruitment approach at nine white-collar workplaces in Wellington was used to attempt to access non-Māori participants with a range of attitudes towards the Māori language. Although this workplace-based design was mainly intended to facilitate access to a range of participants, the data collection also resulted in a number of findings relating to Māori language in the workplace in particular. This report discusses a selection of these findings, including the association between participants’ workplaces and their attitudes towards the Māori language, participants’ stated behaviours towards the Māori language at work (including pronunciation of Māori words, using Māori words and phrases, and responding to the use of Māori by others) and participants’ views on how their workplace environment constrains and/or fosters their Māori language use.

We present Raman spectroscopy measurements on single- and few-layer graphene flakes. By using a scanning confocal approach, we collect spectral data with spatial resolution, which allows us to directly compare Raman images with scanning force micrographs. Single-layer graphene can be distinguished from double- and few-layer by the width of the D' line: the single peak for single-layer graphene splits into different peaks for the double-layer. These findings are explained using the double-resonant Raman model based on ab initio calculations of the electronic structure and of the phonon dispersion. We investigate the D line intensity and find no defects within the flake. A finite D line response originating from the edges can be attributed either to defects or to the breakdown of translational symmetry. [less ▲]

The aim of this paper is to offer new risk indicators that enable one to classify securities of a portfolio according to their risk degrees. These indexes are issued from a new method of the covariance decomposition based on the Shapley Value. The risk indicators are computed via the well-known Gini coefficient, which is viewed as a new risk measure and compared with the traditional measures related with the modern theory of portfolio. These indicators yield suitable information, which could be used by private or institutional investors to trade strategies on market portfolio. [less ▲]

Small-angle neutron scattering has proved to be a valuable technique for probing precipitates in steels. The investigated sample is thereby exposed to a large magnetic field and is assumed to consist of a single domain with all the magnetic moments perfectly aligned with the external field. In this situation the dominating magnetic scattering contrast is expected to stem from the differences between the magnetization values of matrix and particles. However, the present work shows that strong additional scattering can be present which is due to spin misalignment. The effects of this spin-misalignment scattering are discussed as being exemplary for differently heat-treated martensitic steel samples. It is revealed that the amount of spin-misalignment scattering is very sensitive to the applied heat treatment and is most pronounced in the as-quenched condition. In particular, when considering nuclear scattering curves the influence of spin-misalignment scattering may be very large and must not be neglected. [less ▲]

We analyze imperfect competition in dynamic environments where firms use rivalrous but nonexcludable industry-specific capital that is provided exogenously. Capital depreciation depends on utilization, so firms influence the evolution of the capital equipment through more or less intensive supply in the final-goods market. Strategic incentives stem from, (i) a dynamic externality, arising due to the non-excludability of the capital stock, leading firms to compete for its use (rivalry), and, (ii) a market externality, leading to the classic Cournot-type supply competition. Comparing alternative market structures, we isolate the effect of these externalities on strategies and industry growth. [less ▲]

This paper is the first attempt to assess the impact of official FOREX interventions of the three major central banks in terms of the dynamics of the currency components of the major exchange rates (EUR/USD and YEN/USD) over the period 1989-2003. We identify the currency components of the mean and the volatility processes of exchange rates using the recent Bayesian framework developed by Bos and Shephard (2006). Our results show that in general, the concerted interventions tend to affect the dynamics of both currency components of the exchange rate. In contrast, unilateral interventions are found to primarily affect the currency of the central bank present in the market. Our findings also emphasize a role for interventions conducted by these central banks on other related FOREX markets. [less ▲]
