OER Evidence Report 2013-2014

The Open Educational Resources Research Hub (OER Research Hub) provides a focus for research, designed to give answers to the overall question ‘What is the impact of OER on learning and teaching practices?’ and identify the particular influence of openness. We do this by working in collaboration with projects across four education sectors (K12, college, higher education and informal) extending a network of research with shared methods and shared results. The project combines: – Targeted research collaboration with high profile OER projects – A programme of international fellowship – Global networking and expertise in OER implementation and evaluation – A hub for research data and excellence in practice This report is an interim review of evidence recorded against the key hypotheses that focus the research of the OER Research Hub project

Young children’s experiences of music and soundings in museum spaces: lessons, trends and turns from the literature

This article considers the value and role of early years music and sound activities in museum spaces – in relation to children themselves, as well as to their families and wider communities. The article reviews literature around early years music and sound activities; early childhood and the museum; and the use of music and sound in museum spaces – reflecting on reconceptualisation’s of the child within museum spaces and in relation to music and sound. In particular, the article highlights gaps in the literature that present an opportunity to explore the role of music and sound with young children (and particularly with so-called ‘hard-to-reach’ communities or families) within museums

Promises Made, Promises Kept: The Practical Implications of the Private Securities Litigation Reform Act of 1995

This Article suggests approaches that can be taken in addressing the pragmatic concerns of companies with regard to the Private Securities Litigation Reform Act of 1995. These concerns include what form companies\u27 disclosures should take in order to secure the protection of the safe harbor. They also include a need for concrete guidance on the day-to-day response to obligations that are newly required by this statute. Individual directors of companies have no blueprint as to how their boards should respond to this new legislation. This Article provides practical approaches for directors

Simulation of gain stability of THGEM gas-avalanche particle detectors

Charging-up processes affecting gain stability in Thick Gas Electron Multipliers (THGEM) were studied with a dedicated simulation toolkit. Integrated with Garfield++, it provides an effective platform for systematic phenomenological studies of charging-up processes in MPGD detectors. We describe the simulation tool and the fine-tuning of the step-size required for the algorithm convergence, in relation to physical parameters. Simulation results of gain stability over time in THGEM detectors are presented, exploring the role of electrode-thickness and applied voltage on its evolution. The results show that the total amount of irradiated charge through electrode's hole needed for reaching gain stabilization is in the range of tens to hundreds of pC, depending on the detector geometry and operational voltage. These results are in agreement with experimental observations presented previously
