Gender Equity as Policy Paradigm in the Irish Educational Policy Process
The construct of policy paradigm is used to analyse how the proposition that Irish education is a gendered phenomenon has been conceptualized, communicated, reflected in educational policy and acted upon in practice. Intersubjectivity is conceived as a realm of political action in education and the article seeks to excavate it more comprehensively than its usual âglossedâ treatment in educational policy analysis through the schematisation of the construct of policy paradigm. The gender equity paradigm is analysed in terms of this schematisation highlighting its construction, dominion, systematisation, response to counter interpretations of gendered education and possibilities for change.
Genetic Analysis of Irish Populations of Phytophthora Infestans
End of Project ReportPhytophthora infestans (Mont.) de Bary, the causal agent of potato late blight is
best known for its role in the great Irish famine of 1845-1849 which resulted in the
deaths of over 1 million people. Since then, the disease has become established in
all potato growing countries and is the most important pathogen of potatoes
worldwide. The appearance of resistance to the phenylamide fungicides in the late
1970âs indicated that populations of P. infestans were changing. An antiresistance
strategy was developed for growers in an effort to reduce the spread of
resistant strains. Subsequently the A2 mating type of the fungus was discovered in
1989 promoting fears that a super strain of the fungus could evolve through sexual
reproduction. Populations of the fungus have been monitored from 1981 to 1998
for levels of phenylamide resistance and since 1988 for the A2 mating type.
Physiological race surveys were conducted in 1983 and 1996. Prior to the 1980s
no reliable methods were available for adequate identification of genotypes.
Development of molecular markers specific to P. infestans has made this possible
and a survey was conducted on isolates from the 1996 population.
Results confirm that the anti-resistance strategy for phenylamide based fungicides
has been effective in preventing the build up of metalaxyl resistant populations of
P. infestans. During the 1990âs the distribution of phenylamide resistance has
remained stable at about 50% of crops tested compared to a high of over 80 % in
1981. The level of A2 in the population has also fallen from a high of 35% of
isolates tested in 1989 to a static level of 3-4 % in the 1990âs. Physiological race
composition has become much more complex since 1983 and 16 different
physiological races were found in Ireland in 1996. The population was dominated
by race 3.4.7.10.11 which accounted for over 54% of isolates tested. This change
has taken place without a corresponding change to varieties with a complex Rgene
base.
Twelve different genotypes of the fungus were uncovered using the multilocus
probe RG57. Races of the fungus were independent of genotype. One particular
genotype IE-2 was predominantly associated with phenylamide resistance. The
low population diversity discovered suggests that sexual reproduction between A1
and A2 types has not been a major factor in disease epidemiology to date. Super
strains similar to those identified in the USA could not be confirmed.
The overall level of variation in the Irish isolates of Phytophthora infestans would
confirm that the population has become progressively more diverse during the last
forty years. However, the population is much less complex than that found in the
highland tropics of central Mexico.Teagasc Walsh Fellowship Programm
Characterization of AbiR, a novel multicomponent abortive infection mechanism encoded by plasmid pKR223 of Lactococcus lactis subsp. lactis KR2
The native lactococcal plasmid pKR223 encodes two distinct phage resistance mechanisms, a restriction and modification (R/M) system designated LlaKR2I and an abortive infection mechanism (Abi) which affects prolate- headed-phage proliferation. The nucleotide sequence of a 16,174-bp segment of pKR223 encompassing both the R/M and Abi determinants has been determined, and sequence analysis has validated the novelty of the Abi system, which has now been designated AbiR. Analysis of deletion and insertion clones demonstrated that AbiR was encoded by two genetic loci, separated by the LlaKR2I R/M genes. Mechanistic studies on the AbiR phenotype indicated that it was heat sensitive and that it impeded phage DNA replication. These data indicated that AbiR is a novel multicomponent, heat-sensitive, 'early'- functioning Abi system and is the first lactococcal Abi system described which is encoded by two separated genetic loci.Facultad de Ciencias ExactasCentro de InvestigaciĂłn y Desarrollo en CriotecnologĂa de Alimento
STOPP/START criteria for potentially inappropriate prescribing in older people: version 2
Purpose: screening tool of older peopleâs prescriptions (STOPP) and screening tool to alert to right treatment (START) criteria were first published in 2008. Due to an expanding therapeutics evidence base, updating of the criteria was required. Methods: we reviewed the 2008 STOPP/START criteria to add new evidence-based criteria and remove any obsolete criteria. A thorough literature review was performed to reassess the evidence base of the 2008 criteria and the proposed new criteria. Nineteen experts from 13 European countries reviewed a new draft of STOPP & START criteria including proposed new criteria. These experts were also asked to propose additional criteria they considered important to include in the revised STOPP & START criteria and to highlight any criteria from the 2008 list they considered less important or lacking an evidence base. The revised list of criteria was then validated using the Delphi consensus methodology. Results: the expert panel agreed a final list of 114 criteria after two Delphi validation rounds, i.e. 80 STOPP criteria and 34 START criteria. This represents an overall 31% increase in STOPP/START criteria compared with version 1. Several new STOPP categories were created in version 2, namely antiplatelet/anticoagulant drugs, drugs affecting, or affected by, renal function and drugs that increase anticholinergic burden; new START categories include urogenital system drugs, analgesics and vaccines. Conclusion: STOPP/START version 2 criteria have been expanded and updated for the purpose of minimizing inappropriate prescribing in older people. These criteria are based on an up-to-date literature review and consensus validation among a European panel of experts

Prescriber implementation of STOPP/START recommendations for hospitalised older adults: a comparison of a pharmacist approach and a physician approach
Background: Two randomised controlled trials (RCTs) conducted simultaneously in the same Irish university teaching hospital have shown that provision of Screening Tool of Older Personsâ Prescriptions (STOPP)/Screening Tool to Alert doctors to Right Treatment (START) recommendations to attending prescribers by a physician or a pharmacist can reduce in-hospital adverse drug reactions (ADRs) in older adults (â„â65 years). The aims of this study were to compare the prescriber implementation rates of STOPP/START recommendations between the physician approach and the pharmacist approach in these two RCTs and to provide a narrative summary of the comparable clinical outcomes. Methods: Data were extracted from the two RCT published papers and their associated computerised databases to calculate the percentage prescriber implementation rates for the STOPP/START recommendations. The Chi-square test was used to quantify the differences in prescriber implementation rates, with differences considered statistically significant where pâ<â0.05. Results: Prescriber implementation rates of the STOPP and START recommendations made by the physician were 81.2% and 87.4% respectively, significantly higher than those made by the pharmacist (39.2% and 29.5% respectively), pâ<â0.0001. A greater absolute risk reduction in patients with ADRs was shown with the physicianâs intervention compared to the pharmacistâs intervention (9.3% vs 6.8%). Conclusion: This study shows that the methods of communication and the medium through which the STOPP/START recommendations are delivered significantly affect their implementation. Non-implementation of some pharmacist-delivered recommendations may be contributing to preventable ADRs in older adults. Thus, future research should aim to identify the factors influencing prescriber implementation of pharmacist recommendations in order to inform the design of more effective pharmacist interventions in optimising older patientsâ pharmacotherapy

11 C-Metomidate PET/CT is a useful adjunct for lateralization of primary aldosteronism in routine clinical practice.
OBJECTIVE: To describe clinical practice experience of 11 C-Metomidate PET/CT as an adjunct to adrenal vein sampling (AVS) in the lateralization of aldosterone-producing adenomas (APA) in primary aldosteronism (PA). CONTEXT: Accurate lateralization of APA in the setting of PA offers the potential for surgical cure and improved long-term cardiovascular outcomes. Challenges associated with AVS, the current gold standard lateralization modality, mean that only a small proportion of potentially eligible patients currently make it through to surgery. This has prompted consideration of alternative strategies for lateralization, including the application of novel molecular PET tracers such as 11 C-Metomidate. DESIGN: Clinical Service Evaluation/Retrospective audit. PATIENTS: Fifteen individuals with a confirmed diagnosis of PA, undergoing lateralization with 11 C-Metomidate PET/CT prior to final clinical decision on surgical vs medical management. MEASUREMENTS: All patients underwent screening aldosterone renin ratio (ARR), followed by confirmatory testing with the seated saline infusion test, according to Endocrine Society Clinical Practice Guidelines. Adrenal glands were imaged using dedicated adrenal CT. 11 C-Metomidate PET/CT was undertaken due to equivocal or failed AVS. Management outcomes were assessed by longitudinal measurement of blood pressure, ARR, number of hypertensive medications following adrenalectomy or institution of medical therapy. RESULTS: We describe the individual lateralization and clinical outcomes for 15 patients with PA. CONCLUSION: 11 C-Metomidate PET/CT in conjunction with adrenal CT and AVS provided useful information which aided clinical decision-making for PA within a multidisciplinary hypertension clinic
Cost-effectiveness analysis of a physician-implemented medication screening tool in older hospitalised patients in Ireland
Background: A recent randomised controlled trial conducted in an Irish University teaching hospital that evaluated a physician-implemented medication screening tool, demonstrated positive outcomes in terms of a reduction in incident adverse drug reactions. Objective: The present study objective was to evaluate the cost effectiveness of physicians applying this screening tool to older hospitalised patients compared with usual hospital care in the context of the earlier randomised controlled trial. Method: We used a cost-effectiveness analysis alongside a conventional outcome analysis in a cluster randomised controlled trial. Patients in the intervention arm (nâ=â360) received a multifactorial intervention consisting of medicines reconciliation, communication with patientsâ senior medical team, and generation of a pharmaceutical care plan in addition to usual medical and pharmaceutical care. Control arm patients (nâ=â372) received usual medical and pharmaceutical care only. Incremental cost effectiveness was examined in terms of costs to the healthcare system and an outcome measure of adverse drug reactions during inpatient hospital stay. Uncertainty in the analysis was explored using a cost-effectiveness acceptability curve. Results: On average, the intervention arm was more costly but was also more effective. Compared with usual care (control), the intervention was associated with a non-statistically significant increase of âŹ877 (95% confidence interval â âŹ1807, âŹ3561) in the mean healthcare cost, and a statistically significant decrease of â 0.164 (95% confidence interval â 0.257, â 0.070) in the mean number of adverse drug reaction events per patient. The associated incremental cost-effectiveness ratio per adverse drug reaction averted was âŹ5358. The probability of the intervention being cost effective at threshold values of âŹ0, âŹ5000 and âŹ10,000 was 0.236, 0.455 and 0.680, respectively. Conclusion: Based on the evidence presented, this physician-led intervention is not likely to be cost effective compared with usual hospital care. To inform future healthcare policy decisions in this field, more economic analyses of structured medication reviews by other healthcare professionals and by computerised clinical decision support software need to be conducted
Recent developments in German corporate governance.
This paper provides an overview of the German corporate governance system. We review the governance role of large shareholders, creditors, the product market and the supervisory board. We also discuss the importance of mergers and acquisitions, the market in block trades, and the lack of a hostile takeover market. Given that Germany is often referred to as a bank-based economy, we pay particular attention to the role of the universal banks (Hausbanken). We show that the German system is characterised by a market for partial corporate control, large shareholders and bank/creditor monitoring, a two-tier (management and supervisory) board with co-determination between shareholders and employees on the supervisory board, a disciplinary product-market, and corporate governance regulation largely based on EU directives but with deep roots in the German codes and legal doctrine. Another important feature of the German system is its corporate governance efficiency criterion which is focused on the maximisation of stakeholder value rather than shareholder value. However, the German corporate governance system has experienced many important changes over the last decade. First, the relationship between ownership or control concentration and profitability has changed over time. Second, the pay-for-performance relation is influenced by large shareholder control: in firms with controlling blockholders and when a universal bank is simultaneously an equity- and debtholder, the pay-for-performance relation is lower than in widely-held firms or blockholder-controlled firms. Third, since 1995 several major regulatory initiatives (including voluntary codes) have increased transparency and accountability
