Offenders and E-Learning - a literature review on behalf of Becta
This literature review has been prepared by the Hallam Centre of Community Justice at Sheffield Hallam University, on behalf of Becta. The literature review provides a summary of existing research and knowledge relating to e-learning in the offending learning sector with a view to developing a range of e-maturity indicators across the sector. The review also highlights linkages with current Government policy in relation to offender learning and skills
Mental Health And The Role Of The States
Researchers from the State Health Care Spending Project -- a collaboration between The Pew Charitable Trusts and the John D. and Catherine T. MacArthur Foundation -- sought to better understand the country's mental health challenges and, in particular, the states' role in addressing them. The project found that:In 2013, approximately 44 million adults -- 18.5 percent of the population 18 and older -- were classified as having a mental illness. Of these, 10 million had a serious mental illness. The rate of serious mental illness varied from state to state.In 2009, the most recent year for which national mental health data are available, 22 billion (15 percent) in 2009. This total does not include state and local Medicaid expenditures. Counting those contributions brings total state and local spending up to $35.5 billion (24 percent).This report is intended to help federal, state, and local policymakers working to address the country's mental health challenges to better understand their prevalence, treatment, and funding trends
Performance of Network and Service Monitoring Frameworks
The efficiency and the performance of anagement systems is becoming a hot
research topic within the networks and services management community. This
concern is due to the new challenges of large scale managed systems, where the
management plane is integrated within the functional plane and where management
activities have to carry accurate and up-to-date information. We defined a set
of primary and secondary metrics to measure the performance of a management
approach. Secondary metrics are derived from the primary ones and quantifies
mainly the efficiency, the scalability and the impact of management activities.
To validate our proposals, we have designed and developed a benchmarking
platform dedicated to the measurement of the performance of a JMX manager-agent
based management system. The second part of our work deals with the collection
of measurement data sets from our JMX benchmarking platform. We mainly studied
the effect of both load and the number of agents on the scalability, the impact
of management activities on the user perceived performance of a managed server
and the delays of JMX operations when carrying variables values. Our findings
show that most of these delays follow a Weibull statistical distribution. We
used this statistical model to study the behavior of a monitoring algorithm
proposed in the literature, under heavy tail delays distribution. In this case,
the view of the managed system on the manager side becomes noisy and out of
date
