Study made of thin-walled pipe response to turbulent fluids

Report summarizes the experimental and theoretical data on the vibrational response of thin-walled pipe sections to the wall pressure field applied within them by a fully developed turbulent fluid flow. The predicted responses were in good agreement with previous data obtained

Employment and Life-Satisfaction: Insights from Ireland

Mainstream neoclassical economics takes it as given that the consumption of goods and services (output) is positively related to well-being. Work (labour-input) is assumed to be negatively related to well-being at the margin and so is only undertaken in exchange for payment. This view has been challenged for decades in the psychology and sociology literature and results suggests that employment status (especially unemployment) has profound effects on well-being, even at the margin. It is surprising then that several labour force status categories have been under researched in the literature to date. In this paper, using a sample of Irish adults carried out in 2001, we extend the current literature to examine the impacts of additional labour force status categories on life-satisfaction based on International Labour Organisation (ILO) classifications. These include part-time employment, disconnection from the labour force and being disabled, unable to work. Additionally, we expand the analysis of unemployment in the happiness literature and examine if the effects of unemployment and part-time employment on life satisfaction are conditioned by gender. Insights show that being part-time employed has a significant negative effect on life satisfaction, particularly for males. Being unemployed is found to have a significant negative effect on well-being, independent of gender and income, but no such effect is found for the local unemployment rate.

A Study of the Administrative Standards and Practices in Ten Small Eastern Nebraska Schools

This study was undertaken to determine the character of the administrative standards and practices in the small school system. More specifically, the problems involved were: 1. standards and practices of the superintendent as established by the board of education; 2. standards and practices of the board of education to the public; 3. the relationship of the board of education the public; 4. the relationship of the superintendent to the public; 5. the relationship of the board of education to the staff; and 6. the relationship of the superintendent to the staff

Residential home heating: The potential for air source heat pump technologies as an alternative to solid and liquid fuels

AbstractInternational commitments on greenhouse gases, renewables and air quality warrant consideration of alternative residential heating technologies. The residential sector in Ireland accounts for approximately 25% of primary energy demand with roughly half of primary home heating fuelled by oil and 11% by solid fuels. Displacing oil and solid fuel usage with air source heat pump (ASHP) technology could offer household cost savings, reductions in emissions, and reduced health impacts. An economic analysis estimates that 60% of homes using oil, have the potential to deliver savings in the region of €600 per annum when considering both running and annualised capital costs. Scenario analysis estimates that a grant of €2400 could increase the potential market uptake of oil users by up to 17% points, whilst a higher oil price, similar to 2013, could further increase uptake from heating oil users by 24% points. Under a combined oil-price and grant scenario, CO2 emissions reduce by over 4 million tonnes per annum and residential PM2.5 and NOX emissions from oil and peat reduce close to zero. Corresponding health and environmental benefits are estimated in the region of €100m per annum. Sensitivity analyses are presented assessing the impact of alternate discount rates and technology performance. This research confirms the potential for ASHP technology and identifies and informs policy design considerations with regard to oil price trends, access to capital, targeting of grants, and addressing transactions costs

Rethinking functional outcome measures: the development of an upper limb test to assess basal ganglia dysfunction

The basal ganglia is implicated in a wide range of motor, cognitive and behavioural activities required for normal function. This region is predominantly affected in Huntington’s disease (HD), meaning that functional ability progressively worsens. However, functional outcome measures for HD, particularly those for the upper limb, are limited meaning there is an imperative for well-defined, quantitative measures. Here we describe the development and evaluation of the Moneybox test (MBT). This novel, functional upper limb assessment was developed in accordance with translational neuroscience and physiological principles for people with a broad disease manifestation, such as HD. Participants with HD (n=64) and healthy controls (n=21) performed the MBT, which required subjects to transfer tokens into a container in order of size (Baseline Transfer), value (Complex Transfer) with and without reciting the alphabet (Dual Transfer). Disease specific measures of motor, cognition, behaviour and function were collected. HD patients were grouped into disease stage, from which, discriminative and convergent validity was assessed using Analysis of Variance and Pearson’s correlation respectively. Manifest HD participants were slower than pre-manifest and control participants, and achieved significantly lower MBT total scores. Performance in the Complex Transfer and Dual Transfer tasks were significantly different between pre-manifest and stage 1 HD. All MBT performance variables significantly correlated with routinely used measures of motor, cognition, behaviour and function. The MBT provides a valid, sensitive and affordable functional outcome measure. Unlike current assessments, MBT performance significantly distinguished the subtle differences between the earliest disease stages of HD, which are the populations typically targeted in clinical trials

Domestic energy e$ciency in Ireland: correcting market failure

Abstract If the bene"ts of domestic energy eciency are so great, why are they not reaped in actuality and what can be done about it? This paper deals with these crucial questions. It is based on the "ndings of a recent comprehensive study evaluating the costs (labour and materials) and bene"ts (energy cost savings, environmental bene"ts, including reductions in emissions of CO , NO V , SO and PM , comfort gains and mortality and morbidity impacts) to Irish society of bringing the entire housing stock up to the latest Building Regulations. The reasons for the lack of take-up of energy-conservation measures are discussed. The paper formulates policy proposals to address the impediments to e!ective action in the market for domestic energy eciency. The various policy instruments available to overcome these barriers are outlined. Past performance, citing speci"c exemplars, both from abroad and from experience in Ireland, is reported. The "nal section suggests a mix of policy instruments to assist the realisation of the potential bene"ts of the energy-conservation programme. The principal initiatives recommended include the provision of a combination of grants to low-income households and a clear State-led information campaign explaining the bene"ts of conserving energy to the householder

Are you feeling lucky?:lottery-based scheduling for public displays

Scheduling content onto pervasive displays is a complex problem. Researchers have identified an array of potential requirements that can influence scheduling decisions, but the relative importance of these different requirements varies across deployments, with context, and over time. In this paper we describe the design and implementation of a lottery-based scheduling approach that allows for the combination of multiple scheduling policies and is easily extensible to accommodate new scheduling requirements
