An integrated knowledge translation experience: Use of the Network of Pediatric Audiologists of Canada to facilitate the development of The University of Western Ontario Pediatric Audiological Monitoring Protocol (UWO PedAMP v1.0).

The goals of this project were: (1) to determine the important factors that influence implementation of evidence-based practice by Canadian audiologists; and (2) to utilize the knowledge-to-action process (Graham et al., 2006) during the development of a guideline for outcome measures to evaluate the auditory development and performance of young children who wear hearing aids, to facilitate clinical uptake and identify barriers to implementation (Bagatto, Moodie & Scollie, 2010; Bagatto et al., 2011; Bagatto, Moodie, Seewald, Bartlett, & Scollie, 2011; Moodie, Bagatto et al., 2011; Moodie, Kothari et al., 2011). Two projects (Chapters 3 and 4) included the participation of The Network of Pediatric Audiologists of Canada. The outcome measures guideline to evaluate the auditory development and performance of young children who wear hearing aids is called The University of Western Ontario Pediatric Audiological Monitoring Protocol (UWO PedAMP). This body of work includes a chapter on knowledge translation and how it can be used to promote the clinical implementation of evidence in audiology (Chapter 3). It also includes three studies: (1) an examination of factors influencing the use of evidence by Canadian audiologists [Chapter 2]; (2) an initial evaluation by the Network of Pediatric Audiologists of Canada of the individual components considered for inclusion in the UWO PedAMP [Chapter 4]; and (3) a final evaluation by the Network audiologists of the released version of the UWO PedAMP and associated training materials [Chapter 5]. Results of the first study indicated that Canadian audiologists rate themselves as competent in finding, evaluating and using research evidence to change practice. Their greatest barriers to evidence-based practice are related to time. By partnering with Canadian audiologists and using the knowledge-to-action framework to guide us (Chapter 4), we were successful in developing the UWO PedAMP guideline into what they rated as being a high-quality, systematic, hearing aid outcome evaluation tool that improves the quality and effectiveness of audiological care received by young children with hearing loss. The results presented in Chapter 5 indicated that the UWO PedAMP is appropriate for clinical implementation, and is recommended by these Canadian audiologists as preferred audiology practice

A critical review of audiological outcome measures for infants and children

Outcome evaluation is an important stage in the pediatric hearing aid fitting process, however a systematic way of evaluating outcome in the pediatric audiology population is lacking. This is in part due to the need for an evidence-based outcome evaluation guideline for infants and children with hearing loss who wear hearing aids. As part of the development of a guideline, a critical review of the existing pediatric audiology outcome evaluation tools was conducted. Subjective outcome evaluation tools that measure auditory-related behaviors in children from birth to 6 years of age were critically appraised using a published grading system (Andresen, 2000). Of the tools that exist, 12 were appraised because they met initial criteria outlined by the Network of Pediatric Audiologists of Canada as being appropriate for children birth to 6 years of age who wear hearing aids. Tools that were considered for the guideline scored high in both statistical and feasibility criteria. The subjective outcome evaluation tools that were ultimately chosen to be included in the guideline were the LittlEARS Auditory Questionnaire (Tsiakpini et al., 2004) and the Parents\u27 Evaluation of Aural/Oral Performance of Children (PEACH) Rating Scale (Ching & Hill, 2005b) due to the high grades they received in the critical review and their target age ranges. Following this critical review of pediatric outcome evaluation tools, the next step was for the Network Clinicians to evaluate the guideline (Moodie et al., 2011b)

Protocol for the Provision of Amplification

This Protocol addresses the provision of amplification (hereafter: \u27Amplification\u27) to infants and pre-school children who are receiving services from the Ontario Infant Hearing Program (IHP). Providing amplification includes the process of prescribing a hearing aid based on appropriate assessment information, verification that the specified acoustical performance targets have been achieved, fitting the device on the child, and evaluation of device effectiveness in daily life

Virtual QCD corrections to gluon-initiated diphoton plus jet production at hadron colliders

We present an analytic computation of the gluon-initiated contribution to diphoton plus jet production at hadron colliders up to two loops in QCD. We reconstruct the analytic form of the finite remainders from numerical evaluations over finite fields including all colour contributions. Compact expressions are found using the pentagon function basis. We provide a fast and stable implementation for the colour- and helicity-summed interference between the one-loop and two-loop finite remainders in C++ as part of the NJet library

Observation of Sommerfeld precursors on a fluid surface

We report the observation of two types of Sommerfeld precursors (or forerunners) on the surface of a layer of mercury. When the fluid depth increases, we observe a transition between these two precursor surface waves in good agreement with the predictions of asymptotic analysis. At depths thin enough compared to the capillary length, high frequency precursors propagate ahead of the ''main signal'' and their period and amplitude, measured at a fixed point, increase in time. For larger depths, low frequency ''precursors'' follow the main signal with decreasing period and amplitude. These behaviors are understood in the framework of the analysis first introduced for linear transient electromagnetic waves in a dielectric medium by Sommerfeld and Brillouin [1].Comment: to be published in Physical Review Letter

Protocol for the Provision of Amplification v 2023.01

This Protocol addresses the provision of amplification (hereafter: \u27Amplification\u27) to infants and children who are receiving services from the Ontario Infant Hearing Program (IHP). For the purposes of this protocol, providing amplification includes the processes of prescribing a hearing aid (air or bone conduction) and/or other hearing assistance technologies based on appropriate assessment information, verification that the specified acoustical performance targets have been achieved, fitting the device on the child, and ongoing evaluation of device effectiveness in daily life. Amplification within the IHP does not include the provision of cochlear implants
