The Bachelor of Learning Management (BLM) and education capability : why we do not prepare 'teachers' anymore.

This paper explains the underlying logic of a four-year pre-service preparation program, the Bachelor of Management (BLM). The program was designed for post-New Economy knowledge workers in education and training. Its intent is to graduate work-place ready and future-oriented 'learning managers' who have a particular skill in achieving student learning outcomes, rather than 'teachers'. A professional 'business-to-business' arrangement between the teaching profession and Central Queensland University's Faculty of Education and Creative Arts developed the BLM collaboratively in October 2000 and the program enrolled its first students in 2001. The BLM signals a definite shift in emphasis to that of the conventional B.Ed model of teacher education by its four knowledge domains: pedagogy, essential professional knowledge, futures and networks and partnerships. The paper describes how the BLM was developed, some of the major challenges to such innovation and reviews the core concepts of 'learning management' and 'portal task'

Ultrasonic Analytic-Signal Responses From Polymer-Matrix Composite Laminates

Ultrasound has been used to inspect composite laminates since their invention but only recently has the response from the internal plies themselves been considered of interest. This paper uses modeling techniques to make sense of the fluctuating and interfering reflections from the resin layers between plies, providing clues to the underlying inhomogeneities in the structure. It shows how the analytic signal, analyzed in terms of instantaneous amplitude, phase, and frequency, allows 3-D characterization of the microstructure. It is found that, under certain conditions, the phase becomes locked to the interfaces between plies and that the first and last plies have characteristically different instantaneous frequencies. This allows the thin resin layers between plies to be tracked through various features and anomalies found in real composite components (ply drops, tape gaps, tape overlaps, and out-of-plane wrinkles), giving crucial information about conformance to design of as-manufactured components. Other types of defects such as delaminations are also considered. Supporting evidence is provided from experimental ultrasonic data acquired from real composite specimens and compared with X-ray computed tomography images and microsections.</p
