Tribute to A.L. Philpott
It is well known that for more than three decades, A.L. Philpott was an enduring political force in the General Assembly and a powerful influence in many aspects of life in Southside Virginia and beyond
Terry Miller and Mary DeArmond in a Joint Junior Recital
This is the program for the joint junior recital of Terry Miller and Mary DeArmond. Miller performed on the piano; DeArmond performed on the organ. The recital was held on December 6, 1973, in Michell Hall Auditorium
Sowing the Seeds of Trouble: An Historical Analysis of Compliance Structures In Child Welfare
Anitai Etzioni\u27s concept of compliance structures is used as a focus for historical analysis of the organizational structures through which chld welfare services have been offered in the U. S. This article shows how a dual compliance structure arose, both normative and coercive, but with more emphasis on the coercive. The expansion of public child welfare services since 1935, especially foster care and placement services rather than in-home services, has drawn public attention to widespread ineffectiveness. Stress and strain are particularly intense at the service delivery level. Yet the problems and social polices have not been analyzed in terms of building and useing congruent or consistent organizational compliance structures and services to implement then. The authors suggest that Etzioni\u27s organizational compliance theory may be a useful starting point for studying specific organizational responses to parental failure in order to clarify the existing confusion about organizational goals, means, and ends in child welfare
A feasibility study on 3D modelling of cardiac implants in children to improve outcomes in surgery
Objectives: It is both cost effective and practical to computationally model and simulate cardiac implants in a non-invasive environment to identify failure modes and optimise design. This will ultimately improve surgical outcomes faced by children from early implant failure. Methods: The geometries of 3 cardiac implants with increasingly complex features were captured using Agisoft Metashape, a photogrammetric processing software and converted to a 3D model. Anatomical geometries were segmented from a heart DICOM file using Mimics 22.0 and models generated to house the implants. Results: Preliminary surface capturing and modelling was carried out with a 33 mm mitral annuloplasty Dacron ring. Point clouds were successfully generated with high precision and tessellated to generate a 3D model. This was housed in an anatomical model of the mitral annulus and left ventricular outflow tract and computational fluid dynamics carried out using ANSYS 19R2. Blood was modelled during a systolic cardiac cycle as pulsatile and K-epsilon turbulent and Carreau models applied for non-Newtonian blood flow. Discussions: Through high resolution image capturing of the annuloplasty ring, surface features such as ribbing were possible to model. Work is ongoing to assess the feasibility of geometry capturing and computational analysis with a tilting disc and transcatheter aortic valve. Success in the use of these methods in this study will ensure transferability when modelling explanted cardiac implants to determine failure modes. Conclusions: The application of photogammetry to medical devices provides a cost effective and non-invasive method of analysing critical failure modes of implants that can be missed in patient scans. This will lead to device optimisation and will improve outcomes in paediatric cardiac surgery.

The impact of information and communications technology on teaching and design of flexible, online and distance education courses at Deakin University
This paper describes the use of an online learning environment which has been established for postgraduate students studying at Master’s level in Professional Education and Training Deakin University. A detailed evaluation of the use of computer conferences in an Open and Distance Education specialism was undertaken during 2000 as part of a CUTSD funded project, Learner Centred Evaluation of Computer Facilitated Learning Projects in Higher Education. As the Open and Distance Education specialism is being revised and new units are written, the information gathered in this evaluation is being integrated into the pedagogical planning and the technological decisions being made about the design of the new master’s program.</div
