Does emotional resilience enhance foster placement stability? A qualitative investigation.
No full textFrequent changes of foster placement are known to have a detrimental effect on the long-term well-being of cared for children. Foster carers who take on children with challenging behaviours have to draw on resources, both internal and external, to help them build and maintain a relationship with the child that will last. Not all foster carers are successful in this regard. The aim of this qualitative study was to explore the role that the emotional resilience of foster carers plays in promoting placement stability.
Seven foster carers, who had a track-record of stable placements (according to national criteria) with children exhibiting challenging behaviours, were recruited from a Local Authority in the North East of England. They attended a focus group and one-to-one interview. Verbatim transcripts were subjected to an inductive grounded theory analysis.
Three potential underlying constructs, namely emotional resilience, interpersonal characteristics and external factors, were found to emerge from the data and identified as likely to influence foster placement outcomes. These data provide a springboard for further quantitative investigation with the potential to screen prospective carers to identify those best suited to ‘difficult’ placements in order to maximise success for the benefit of all concerned
Views of children and young people in foster care survey: education
No full textThis paper explores the educational experiences of children and young people living in foster care in Queensland. Findings are drawn from the responses of 845 children and 1180 young people to the 2011 Views of Children and Young People in Foster Care survey, which is a rich source of information about children’s and young people’s attitudes towards and perceptions of their own education. Findings relate to educational status, key markers of educational disadvantage including suspensions and exclusions, and specific problems children and young people experience at school, as well as children’s and young people’s enjoyment of school and aspirations for the future. Information about educational support, including Educational Support Plans and support provided by Child Safety Officers and Community Visitors are also presented. Where relevant, comparisons are made between the 2011 survey results and prior surveys conducted in 2006, 2007 and 2009. Relationships between key educational measures as well as relationships to other important measures of health and placement stability are also explored.
The findings suggest that children and young people continue to experience educational disadvantage, including high rates of suspension and exclusion and a range of problems at school including problems with schoolwork, bullying and behaviour and that these difficulties can be exacerbated by the child protection system, for example, through placement instability. However, there are reasons for optimism. Children and young people are overwhelmingly likely to report that they enjoy school, expect to complete Year 12 and that their teachers generally like their schoolwork. Furthermore, over time, the proportions of young people reporting that they have an Educational Support Plan have grown, and, importantly, they are more likely to report that these plans are helpful. Analyses in relation to a number of educational variables reveal that young people with a plan they consider to be helpful fare better. Children and young people were also positive about the important role that CSOs and CVs are able to play in supporting their education.
While educational disadvantage is an enduring problem, the survey findings provide evidence of progress in key areas and suggestions for how continued improvements may be made

Continuous metadata flows for distributed multimedia
No full textThe practical use of temporal multimedia has increased markedly in recent years as enabling technologies for the distribution and streaming of media have become available. As a part of this trend, hypermedia systems and models have adapted accordingly to incorporate such distributed multimedia for presentation. Structured interpretation of information has long been a fundamental feature of both open hypermedia systems and knowledge systems. Metadata, in its many forms, has become the cornerstone for providing this structured knowledge above and beyond basic data and information. This thesis presents the rationale and requirements for continuous metadata, which supports the metadata accompanying distributed multimedia throughout the lifecycle of streamed media, from generation, through distribution, to presentation. Throughout this process it is the temporal and continuous nature of the metadata which is paramount. A conceptual framework for continuous metadata is proposed to encapsulate these principles and ideas. Continuous metadata and the associated framework enable the development, in particular, of real-time, collaborative, semantically enriched distributed multimedia applications. Experience building one such system using continuous metadata is evaluated within the framework. An ontology is developed for the system to enable the collation, distribution, and presentation of structure aiding navigation of multimedia, and it is shown how continuous metadata utilising the ontology can be distributed using multicas

Research Agenda for the Semantic Grid: A Future e-Science Infrastructure
No full texte-Science offers a promising vision of how computer and communication technology can support and enhance the scientific process. It does this by enabling scientists to generate, analyse, share and discuss their insights, experiments and results in a more effective manner. The underlying computer infrastructure that provides these facilities is commonly referred to as the Grid. At this time, there are a number of grid applications being developed and there is a whole raft of computer technologies that provide fragments of the necessary functionality. However there is currently a major gap between these endeavours and the vision of e-Science in which there is a high degree of easy-to-use and seamless automation and in which there are flexible collaborations and computations on a global scale. To bridge this practice–aspiration divide, this report presents a research agenda whose aim is to move from the current state of the art in e-Science infrastructure, to the future infrastructure that is needed to support the full richness of the e-Science vision. Here the future e-Science research infrastructure is termed the Semantic Grid (Semantic Grid to Grid is meant to connote a similar relationship to the one that exists between the Semantic Web and the Web)
Evaluating Research Impact through Open Access to Scholarly Communication
No full textScientific research is a competitive business – in order to secure funding, promotion and tenure researchers must demonstrate their work has impact in their field. To maximise impact researchers undertake high priority research, aim to get results first, and publish in the highest impact journals. The Internet now presents a new opportunity to the scholarly author seeking higher impact: s/he can now make their work instantly accessible on the Web through author self-archiving. This growing body of open access literature (coupled with new publishing models that make journals available for-free to the reader) maximises research impact by maximising the number of people who can read it, and making it available sooner. Open access also provides a new opportunity for bibliometric research. This thesis describes the relatively recent phenomenon of open access to research literature, tools that were built to collect and analyse that literature, and the results of analyses of the effect of open access and its effect on author behaviour. It shows that articles self-archived by authors receive between 50-250% more citations, that rapid pre-printing on the Web has dramatically reduced the peak citation rate from over a year to virtually instant and how citation-impact – now widely used for evaluation – can be expanded to include a new web metric of download impact
