The Langmuir probe as a diagnostic of the electron component within low temperature laser ablated plasma plumes

A Langmuir probe has been used as a diagnostic of the temporally evolving electron component within a laser ablated Cu plasma expanding into vacuum, for an incident laser power density on target similar to that used for the pulsed laser deposition of thin films. Electron temperature data were obtained from the retarding region of the probe current/voltage (I/V) characteristic, which was also used to calculate an associated electron number density. Additionally, electron number density data were obtained from the saturation electron current region of the probe (I/V) characteristic. Electron number density data, extracted by the two different techniques, were observed to show the same temporal form, with measured absolute values agreeing to within a factor of 2. The Langmuir probe, in the saturation current region, has been shown for the first time to be a convenient diagnostic of the electron component within relatively low temperature laser ablated plasma plumes.

An Inconvenient Truth: Barriers to Truth Recovery in the Aftermath of Institutional Child Abuse in Ireland

Contemporary settled democracies, including the United States, England and Wales and Ireland, have witnessed a string of high profile cases of institutional child abuse in both church and state settings. Set against the broader literature on transitional justice, this analysis argues that there are significant barriers to truth recovery within the particular context of historical institutional abuse by the clergy in the Republic of Ireland. In the main, I argue that the frameworks of the inquiries and commissions into historical institutional child abuse are not conducive to truth recovery or the search for justice in dealing with the legacy of an abusive past. It is the church-state relationship which makes the Irish situation noteworthy and unique. The Catholic Church and child care institutions are especially self-protective, secretive and closed by nature and strongly discourage the drawing of attention to any deficiencies in organisational procedures. The nature of the public inquiry process also means that there is often a rather linear focus on accountability and apportioning blame. Collectively, such difficulties inhibit fuller systemic investigation of the veracity of what actually happened and, in turn, meaningful modification of child care policies. The article concludes by offering some thoughts on implications for transitional justice discourses more broadly as well as the residual issues for Ireland and other settled democracies in terms of moving on from the legacy of institutional child abuse.

A normative approach to the criminalisation of cartel activity

Although cartel behaviour is almost universally (and rightly) condemned, it is not clear why cartel participants deserve the full wrath of the criminal law and its associated punishment. To fill this void, I develop a normative (or principled) justification for the criminalisation of conduct characteristic of ‘hard core’ cartels. The paper opens with a brief consideration of the rhetoric commonly used to denounce cartel activity, eg that it ‘steals from’ or ‘robs’ consumers. To put the discussion in context, a brief definition of ‘hard core’ cartel behaviour is provided and the harms associated with this activity are identified. These are: welfare losses in the form of appropriation (from consumer to producer) of consumer surplus, the creation of deadweight loss to the economy, the creation of productive inefficiency (hindering innovation of both products and processes), and the creation of so-called X-inefficiency. As not all activities which cause harm ought to be criminalised, a theory as to why certain harms in a liberal society can be criminalised is developed. It is based on JS Mill's harm to others principle (as refined by Feinberg) and on a choice of social institutions using Rawls's ‘veil of ignorance.’ The theory is centred on the value of individual choice in securing one's own well-being, with the market as an indispensable instrument for this. But as applied to the harm associated with cartel conduct, this theory shows that none of the earlier mentioned problems associated with this activity provide sufficient justification for criminalisation. However, as the harm from hard core cartel activity strikes at an important institution which permits an individual's ability to secure their own well-being in a liberal society, criminalisation of hard core cartel behaviour can have its normative justification on this basis.

Early diagnosis improves survival in kidney cancer

Kidney cancers account for 2-3% of all adult malignancies in the UK. Men are predominantly affected by renal cancer with an average age at diagnosis of 64 years. Renal (or clear) cell carcinoma (RCC) accounts for 90% of kidney cancers. Early diagnosis improves survival with five-year survival rates for renal cancer of 70-94% for localised tumours in the UK. RCC should be suspected in the presence of localising symptoms such as flank pain, a loin mass or haematuria; constitutional upset including weight loss, pyrexia and/or night sweats; or with unexplained laboratory tests. Smoking, obesity and hypertension are the most important and most common risk factors. Environmental exposure to asbestos, cadmium and trichloroethylene are less common risk factors. Patients on chronic dialysis and renal transplant recipients are at increased risk of RCC in their native kidneys. If kidney cancer is suspected on history, physical examination or initial screening tests then a red flag ultrasound examination of the renal tracts should be requested. Dipstick urinalysis is of great value as asymptomatic haematuria may be the only abnormal test in the presence of non-specific symptoms such as weight loss or loin pain. Visible or non-visible haematuria, in the absence of proteinuria, suggests an underlying structural abnormality is present in the kidneys, ureters or bladder. Surgical removal of RCCs, where feasible, may result in cure in up to 40-60% of cases. Individuals too frail for major surgery may benefit from thermal ablation and cryotherapy. Agents that target the VEGF and mTOR pathways are considered first line in the treatment of metastatic RCC. Sunitinib, recommended by NICE, is administered orally and acts by inhibiting the VEGF receptor.

Demersal fish biodiversity: species-level indicators and trends-based targets for the Marine Strategy Framework Directive

The maintenance of biodiversity is a fundamental theme of the Marine Strategy Framework Directive. Appropriate indicators to monitor change in biodiversity, along with associated targets representing "good environmental status" (GES), are required to be in place by July 2012. A method for selecting species-specific metrics to fulfil various specified indicator roles is proposed for demersal fish communities. Available data frequently do not extend far enough back in time to allow GES to be defined empirically. In such situations, trends-based targets offer a pragmatic solution. A method is proposed for setting indicator-level targets for the number of species-specific metrics required to meet their trends-based metric-level targets. This is based on demonstrating significant departures from the binomial distribution. The procedure is trialled using North Sea demersal fish survey data. Although fisheries management in the North Sea has improved in recent decades, management goals to stop further decline in biodiversity, and to initiate recovery, are yet to be met.

Learning curves, taking instructions, and patient safety:using a theoretical domains framework in an interview study to investigate prescribing errors among trainee doctors

ABSTRACT:

Beyond the boundaries in the island of Ireland

The review essay opens with positive attributes of Ireland but then considers that the island has been subject to centuries of bitter dispute and unrest. The historical background to this is outlined, particularly the interactions between Ireland and its neighbouring island, Great Britain, which dominated Irish affairs. One policy adopted by the British was to encourage migration of Protestants into the largely Catholic island in the vain hope that this would reduce unrest. The
two islands were then united from 1801 as the United Kingdom of Great Britain and Ireland but demands from indigenous Irish Catholics for independence continued, resisted by the Protestant minority who wished to remain inside the UK. After the Great War a solution was imposed that granted most of Ireland independence but left the largely Protestant northeast corner within the UK as Northern Ireland. Reaction to and life with the Irish border are considered and the paper concludes with musings about its future.

ENVIRONMENTAL LIMITS ON THE NONRESONANT COSMIC-RAY CURRENT-DRIVEN INSTABILITY

We investigate the so-called nonresonant cosmic-ray streaming instability, first discussed by Bell (2004). The extent to which thermal damping and ion-neutral collisions reduce the growth of this instability is calculated. Limits on the growth of the nonresonant mode in SN1006 and RX J1713.7-3946 are presented.

Learning transfer in multinational companies:Explaining inter-organisation variation

This article addresses the extent to which multinational companies (MNCs) in Ireland deploy practices aimed at the transfer of learning in their operations and the factors explaining inter-organisation variation in so doing. Using data from 260 MNCs, we find that comparatively large numbers of firms deploy practices to transfer learning in their Irish operations. Most notably, we find that almost half of all MNCs have a formal policy on organisational learning, while more than six in every ten MNCs in Ireland utilise three or more learning transfer mechanisms. In investigating inter-organisation variation with respect to these, we test a number of hypotheses involving nationality, sectoral, MNC (e.g. organisation structure) and HR factors. Our results show that the presence of international HR structures is a significant factor in explaining learning transfer in MNCs. We also find support that employment size, sector and integration between the MNC's global operations are useful variables in explaining variation in the deployment of practices on learning transfer in MNCs. © 2009 Blackwell Publishing Ltd.

Understanding how HR systems work: the role of HR philosophy and HR processes

Despite the proliferation of studies of HR systems, there are still substantial gaps in our understanding
of how such systems actually work. This article, by focusing on the neglected areas of HR philosophy
and HR processes in the composition of HR systems, and by using a qualitative, employee-centred
approach in the collection and analysis of data, provides new insights into the working of HR systems.
Using data from interviews with 56 knowledge workers employed in the information and
communications technology sector in Ireland and the UK, we explore employee-level reactions to two
different types of HR systems. We highlight the various ways in which HR processes interact with HR
practices and the different outcomes that may result, and we identify the key role of HR philosophy in
HR system operation.

Clinical Characteristics of Reticular Pseudodrusen in the Fellow Eye of Patients with Unilateral Neovascular Age-Related Macular Degeneration

Purpose: To describe associations between reticular pseudodrusen, individual characteristics, and retinal function.

Design: Cohort study.

Participants: We recruited 105 patients (age range, 52–93 years) who had advanced neovascular age-related macular degeneration (AMD) in only 1 eye from 3 clinical centers in Europe.

Methods: Minimum follow-up was 12 months. The eye selected for study was the fellow eye without advanced disease. Clinical measures of vision were distance visual acuity, near visual acuity, and results of the Smith-Kettlewell low-luminance acuity test (SKILL). Fundus imaging included color photography, red-free imaging, blue autofluorescence imaging, fluorescein angiography, indocyanine green angiography, and optical coherence tomography using standardized protocols. These were used to detect progression to neovascular AMD in the study eye during follow-up. All imaging outputs were graded for the presence or absence of reticular pseudodrusen (RPD) using a multimodal approach. Choroidal thickness was measured at the foveal center and at 2 other equidistant locations from the fovea (1500 μm) nasally and temporally. Metrics on retinal thickness and volume were obtained from the manufacturer-supplied automated segmentation readouts.

Main Outcome Measures: Presence of RPD, distance visual acuity, near visual acuity, SKILL score, choroidal thickness, retinal thickness, and retinal volume.

Results: Reticular pseudodrusen was found in 43 participants (41%) on 1 or more imaging method. The SKILL score was significantly worse in those with reticular drusen (mean score ± standard deviation [SD, 38±12) versus those without (mean score ± SD, 33±9) (P = 0.034). Parafoveal retinal thickness, parafoveal retinal volume, and all of the choroidal thickness parameters measured were significantly lower in those with reticular drusen than in those without. The presence of RPD was associated with development of neovascular AMD when corrected for age and sex (odds ratio, 5.5; 95% confidence interval, 1.1–28.8; P = 0.042). All participants in whom geographic atrophy developed during follow-up had visible RPD at baseline.

Conclusions: Significant differences in retinal and choroidal anatomic features, visual function, and risk factor profile exist in unilateral neovascular AMD patients with RPD compared with those without; therefore, such patients should be monitored carefully because of the risk of developing bilateral disease.

Recessionary Bundles: HR Practices in the Irish Economic Crisis

The HR practices adopted by firms in response to the current deep and prolonged recession have received little attention in the literature. There are reasons for supposing that firms will adopt HR practices in bundles in responding to the recession in order to benefit from technical and behavioural complementarities. Drawing on a nationally representative survey, the article investigates the bundles of HR practices adopted by firms during the Irish recession and examines influences on the bundles that are evident. The article contributes to HRM theory by testing different views on HR bundles likely to be adopted in recessionary conditions and by moving beyond the prevailing focus in HRM on HR bundles adopted by firms in steady-state business conditions.

“Bound in darkness and idolatry”? Protestant working class underachievement and Unionist hegemony

Over the past decade or more there has been a growing concern at the levels of educational underachievement within loyalist working-class areas of Northern Ireland. The inability of both educational and social policy initiatives over the past decade to improve the situation in any meaningful way has raised important questions concerning how the problem can be tackled more effectively. Placing the issue within the theoretical framework of Gramsci’s hegemony, this paper argues that there is a need to better understand the historical nature of the problem and to recognise the political and social forces that have shaped its existence. It argues that there is a need to move away from explaining Protestant underachievement simply by the availability of jobs in Ulster’s industrial past and to place its roots in the complex battle for social, political, and economic power since the 1801 Act of Union.
