Competitiveness Implications for Ireland of EU Enlargement
Ten states, primarily from Central and Eastern Europe, are likely to be admitted to the EU within the next few years. The present paper assesses the competitiveness implications of this enlargement for Ireland. Four specific topics are considered - the trade effects, the implications for Ireland?s ability to attract FDI, the likely levels of immigration from Central and Eastern Europe and its consequences, and the budgetary implications for the Irish Exchequer.
Soluble RAGE: a hot new biomarker for the hot joint?
The receptor for advanced glycation endproducts (RAGE) interacts with distinct ligand families linked to the inflammatory response. Studies in animal models suggest that RAGE is upregulated in the inflamed joint and that blockade of the receptor, using a ligand decoy soluble form of RAGE (sRAGE), attenuates joint inflammation and expression of inflammatory and tissue-destructive mediators. In this issue of Arthritis Research & Therapy, Rille Pullerits and colleagues reported that plasma levels of sRAGE were reduced in subjects with rheumatoid arthritis compared with healthy controls or subjects with non-inflammatory joint disease. These findings suggest the possibility that levels of sRAGE might be a biomarker of inflammation. Not resolved by these studies, however, is the intriguing possibility that endogenously higher levels of sRAGE might be linked to a lower incidence of arthritis or to the extent of inflammation. Nevertheless, although 'cause or effect' relationships may not be established in this report, fascinating insights into RAGE, inflammation and human arthritis emerge from these studies
eGovernment in Execution: Building Organizational Infastructure
This paper presents a sub-framework detailing critical aspects of organizational infrastructure for egovernment. According to an Accenture study performed in early 2001, Canada ranked first as a worldwide leader in e-government practices. However, the results of a survey of municipal e-government web sites in Canada illustrate how the absence of organizational infrastructure for egovernment has resulted in very little diffusion across the country. We speculate that excellence in e-government can only become widespread if formal organizational infrastructure with its accompanying diffusion networks and mechanisms are put in place
Seed Production and Resource Allocation in Three Cultivars of \u3cem\u3eAchnatherum Hymenoides\u3c/em\u3e, Nevada, USA
Plant production is partially determined by resource allocation among various organs (Monsi & Murata, 1970), however, studies on dry matter partitioning among different plant organs are scarce in general (Marceli, 1996), and lacking in Achnatherum hymenoides. This study compared dry matter production and partitioning among three commercial cultivars (Paloma, Nezpar and Rimrock) of A. hymenoides and identified growth and developmental characteristics that could indicate potential seed production. In addition, the relationship between an organ weight as a percent of total aerial plant biomass was assessed
Intermediate filament–membrane attachments function synergistically with actin-dependent contacts to regulate intercellular adhesive strength
By tethering intermediate filaments (IFs) to sites of intercellular adhesion, desmosomes facilitate formation of a supercellular scaffold that imparts mechanical strength to a tissue. However, the role IF–membrane attachments play in strengthening adhesion has not been directly examined. To address this question, we generated Tet-On A431 cells inducibly expressing a desmoplakin (DP) mutant lacking the rod and IF-binding domains (DPNTP). DPNTP localized to the plasma membrane and led to dissociation of IFs from the junctional plaque, without altering total or cell surface distribution of adherens junction or desmosomal proteins. However, a specific decrease in the detergent-insoluble pool of desmoglein suggested a reduced association with the IF cytoskeleton. DPNTP-expressing cell aggregates in suspension or substrate-released cell sheets readily dissociated when subjected to mechanical stress whereas controls remained largely intact. Dissociation occurred without lactate dehydrogenase release, suggesting that loss of tissue integrity was due to reduced adhesion rather than increased cytolysis. JD-1 cells from a patient with a DP COOH-terminal truncation were also more weakly adherent compared with normal keratinocytes. When used in combination with DPNTP, latrunculin A, which disassembles actin filaments and disrupts adherens junctions, led to dissociation up to an order of magnitude greater than either treatment alone. These data provide direct in vitro evidence that IF–membrane attachments regulate adhesive strength and suggest furthermore that actin- and IF-based junctions act synergistically to strengthen adhesion
Te Mata Ira: Guidelines for Genomic Research with Māori.: Te Mata Ira: Guidelines for Genomic Research with Māori.
Māori ethical frameworks recognise that all research in New Zealand is of interest to Māori and outline community expectations of appropriate behavior in research to deliver the best outcomes for Māori. Research contributes to the
broader development objectives of society. Ethics has a specific role in guiding key behaviours, processes and methodologies used in research.
This document outlines a framework for addressing Māori ethical issues within the context of genetic or genomic research. It draws on a foundation of mātauranga
(Māori knowledge) and tikanga Māori (Māori protocols and practices) and will be useful for researchers, ethics committee members and those who engage in consultation or advice about genomic research with Māori in local, regional,
national or international settings
Deceleration of a supersonic beam of SrF molecules to 120 m/s
We report on the deceleration of a beam of SrF molecules from 290 to 120~m/s.
Following supersonic expansion, the molecules in the (, )
low-field seeking states are trapped by the moving potential wells of a
traveling-wave Stark decelerator. With a deceleration strength of 9.6 km/s
we have demonstrated the removal of 85 % of the initial kinetic energy in a 4
meter long modular decelerator. The absolute amount of kinetic energy removed
is a factor 1.5 higher compared to previous Stark deceleration experiments. The
demonstrated decelerator provides a novel tool for the creation of highly
collimated and slow beams of heavy diatomic molecules, which serve as a good
starting point for high-precision tests of fundamental physics

A Bright, Slow Cryogenic Molecular Beam Source for Free Radicals
We demonstrate and characterize a cryogenic buffer gas-cooled molecular beam
source capable of producing bright beams of free radicals and refractory
species. Details of the beam properties (brightness, forward velocity
distribution, transverse velocity spread, rotational and vibrational
temperatures) are measured under varying conditions for the molecular species
SrF. Under typical conditions we produce a beam of brightness 1.2 x 10^11
molecules/sr/pulse in the rovibrational ground state, with 140 m/s forward
velocity and a rotational temperature of approximately 1 K. This source
compares favorably to other methods for producing beams of free radicals and
refractory species for many types of experiments. We provide details of
construction that may be helpful for others attempting to use this method.Comment: 15 pages, 14 figure
