Load sharing in cluster service provision

The factors that are driving the development and use of grids and grid computing, such as size, dynamic features, distribution and heterogeneity, are also pushing to the forefront service quality issues. These include performance, reliability and security. Although grid middleware can address some of these issues on a wider scale, it has also become imperative to ensure adequate service provision at local level. Load sharing in clusters can contribute to the provision of a high quality service, by exploiting both static and dynamic information. This paper is concerned with the presentation of a load sharing scheme, that can satisfy grid computing requirements. It follows a proactive, non preemptive and distributed approach. Load information is gathered continuously before it is needed, and a task is allocated to the most appropriate node for execution. Performance and reliability are enhanced by the decentralised nature of the scheme and the symmetric roles of the nodes. In addition, the scheme exhibits transparency characteristics that facilitate integration with the grid.

Finance for water and sanitation as a public service

Drawing on empirical evidence gathered through the PSIRU database, this contribution aims at addressing the potential of public finance to enhance the provision of water supply and sanitation as a public service. It highlights the problems associated with (and the disappointing results obtained from) resort to Private Sector Participation and private finance, both historically and in the last 15-20 years, in developed and developing countries. It also addresses the advantages of using public finance as a more cost-effective and equitable instrument to achieve developmental objectives such as the expansion of service coverage and development of water and sanitation infrastructure. The potential of public operations in maximising developmental impact from the social, economic and environmental points of view is then explored referring to specific examples from a variety of countries and regions. These include the in-house restructuring of public operations to enhance transparency, accountability and effectiveness, as well as the use of Public-Public Partnerships (PUPs) to build capacity. Attention is devoted to the specific financial requirements of expanding sewerage services at global level to achieve MDGs or broader developmental goals. These requirements are revisited in light of a regional breakdown of coverage gaps, available resources and development aid flows. These findings challenge the established view among international and bilateral agencies that expanding sewerage services in developing countries is excessively costly and should be abandoned as a priority because unaffordable. This contribution draws on a number of PSIRU Reports, and particularly the following. - http://www.psiru.org/reports/2008-03-W-sewers.pdf - http://boell-latinoamerica.org/download_es/agua08_privatizacion_LA_2007.pdf - http://boell-latinoamerica.org/download_es/agua08_agua_un_servicio_publico.pdf - http://www.psiru.org/reports/2006-03-W-investment.pdf All PSIRU Reports are accessible at http://www.psiru.org/publicationsindex.asp.

Are adolescents/young people and their families getting the best service when being cared for by young adolescent student nurses?

The purpose of this presentation is to highlight issues that exist for student nurses who embark on a career in children's nursing at a very young age and subsequently find themselves in a situation where they are expected to deliver high quality care to young people and their families. An introductory sentence indicating the purpose of the presentation: Currently in the UK under the Making a Différence Curriculum (DOH 1999) students can enrol on a single registration programme for Children's Nursing as young as 17.5 years. Children are admitted to hospital onto the children's wards between the ages of 0-16 years (occasionally older). Using Viner's (2003) définition of adolescence as being that period between the ages of ten and twenty-five years when biopsychosocial maturation leads to functional independence in adult iife demonstrates the possibility that both the patients and the nursing students could be undergoing very similar transitional experiences. Historically, in the 1940-50's children were admitted to childrens wards between the ages of 2-12 years. Nurse education at that time tended to be undertaken for first or second level registration in the first instance, followed by post-registration training for specialist areas. Subsequently, the phenomenon of adolescent paediatric nursing students being required to care for adolescents and their families on the children's wards did not exist some 60 years ago. A brief description of the highiights of the présentation: This présentation will focus on adolescent transitions with particular reference to issues that could arise when young students are required to care for young people and their families, particularly when there is a diagnosis of self harm or substance abuse. A summary of findings and/or other relevant information: Preliminary findings have indicated that very young student nurses find caring for adolescents to be particularly challenging. Health issues pertinent to young people appear to présent particular challenges for the students which raises questions in respect of the quality of care that the young people and their families may receive. A conclusion and implications: The following need to be further explored: i) Support within the clinical areas and adequate de-briefing strategies, ii) The efficacy of single registration to children's nursing, iii) Young people and their family's perception of the quality of care they receive from very young students.
