    An air force pilot draws on memories of home to help him complete a plane refueling task. Articles, stories, and other compositions in this archive were written by participants in the Mighty Pen Project. The program, developed by author David L. Robbins, and in partnership with Virginia Commonwealth University and the Virginia War Memorial in Richmond, Virginia, offers veterans and their family members a customized twelve-week writing class, free of charge. The program encourages, supports, and assists participants in sharing their stories and experiences of military experience so both writer and audience may benefit

    'I’m Glad to Know I’m Not Going Mad!': The Use of Videos of Authentic Classroom Practice to Prompt Collaborative Reflective Practice Among Second Level Modern Foreign Languages Teachers

    The aim of this publication is to present how Open Educational Resources (OERs) are being strongly promoted at all levels of education. This book presents a select number of case studies from contributors to the Irish National Digital Learning Resources (NDLR) service. The scarcity of inside views of real Irish classrooms and especially the dearth of video-based resources that depict these, coupled with increased expectations for teacher education providers to work together (DES 2011), were among the considerations that motivated and shaped the development of the project described in this chapter. Video Ideas in Teaching and Learning Languages (VITALL) is a collaboration between the Education Department in NUI Maynooth, the Professional Development Service for Teachers (PDST) and the Post-Primary Languages Initiative (PPLI). It seeks to address, in one initiative, our shared concerns in relation to the production and use of resources to support the professional development of second level modern language teachers in Ireland

    Thin-Film Sol-Gel as Controlled Delivery Platform for Neural Microelectrodes

    Long-term efficacy of neural implantation devices is a persisting challenge in neural engineering and rehabilitation. Upon implantation of a neural device, the foreign body response (FBR) is triggered and glial cells form a sheath around the electrode array. This sheath isolates the array from the rest of the brain both mechanically and electrically. Tetramethyl orthosilicate (TMOS), a thin-film polymer, has been shown to not negatively impact the impedance and charge-carrying capacity, as well as offer a controlled delivery method to deliver pharmaceuticals to mitigate inflammation without significant effect to device design. Using an in vitro protein delivery model to analyze the ability of multiple layers of TMOS to be used for protein delivery from both silicon wafers and microelectrodes, we evaluated the release kinetics and surface properties of the coatings. Through the wafer analysis, results reflect that adding a layer of TMOS significantly lowered ‘burst release’ of the protein, bovine serum albumin (BSA). Coating wafer with freshly-made TMOS prolonged the protein release period. Total protein released per number of coats had no linear correlation, possibly due to nonuniform thickness of coats or protein trapped between multiple layers. From these findings, we speculate the possibility of a gradual release model for the utility of TMOS-coated microelectrodes in neural devices

    Across-country genetic evaluation of meat sheep from Ireland and the United Kingdom

    Genetic evaluations in sheep have proven to be an effective way of increasing farm profitability. Much research has previously been conducted on producing within‐country genetic evaluations; however, to date, no across‐country sheep genetic evaluations have been produced between Ireland and the UK. The objective of the present study was to examine the feasibility of an across‐country genetic evaluation of live body weight and carcass composition traits for Texel sheep raised in Ireland and the UK. The benefit of genetic selection based on across‐country genetic evaluations, in comparison with within‐country genetic evaluations, was also quantified. Animal traits included early‐life and postweaning live body weights, and muscle and fat depth ultrasound measurements. Irish and UK data were combined, common animals with progeny with records in both countries were identified and a series of bivariate analyses were performed separately for each trait to produce across‐country genetic evaluations. Fixed effects included contemporary group, age at first lambing of the dam, parity of the dam (Ireland), dam age at lamb's birth (UK), a gender by age of the lamb interaction, a birth type by rearing type of the lamb interaction and country of birth of the lamb. Random effects included the animal additive genetic, dam maternal, litter common environment and residual effect. The model for postweaning weight, muscle depth and fat depth included only the animal additive genetic and litter common environmental random effects. Genetic correlations between the two countries ranged from 0.82 to 0.88 for the various traits. Across‐country breeding values were estimated for all animals and response to selection was predicted using the top 10 and top 20 sires in both within‐ and across‐country analyses for the two countries. Overall, results showed that rates of genetic gain could potentially increase from between 2.59% and 19.63% from selection based on across‐country genetic evaluations compared to within‐country evaluations alone. Across‐country evaluations are feasible and would be of significant benefit to both the Irish and UK sheep industries. In order to realize these potential gains though, there would need to be a switch in emphasis by sheep breeders towards using objective traits as their primary selection criteria
