Polymeric scaffolds used in regenerative therapies are implanted in the damaged tissue and submitted to repeated loading cycles. In the case of articular cartilage engineering, an implanted scaffold is typically subjected to long-term dynamic compression. The evolution of the mechanical properties of the scaffold during bioresorption has been deeply studied in the past, but the possibility of failure due to mechanical fatigue has not been properly addressed. Nevertheless, the macroporous scaffold is susceptible to failure after repeated loading-unloading cycles. In this work fatigue studies of polycaprolactone scaffolds were carried by subjecting the scaffold to repeated compression cycles in conditions simulating …

Embracing Complexity In Engineering Education: A Way Forward For Developing Intercultural Competency, Thomas Goldfinch
Faculty of Engineering and Information Sciences - Papers: Part A
towards engineering education that prepares graduates to work effectively across foreign cultures and customs1-3. The author argues that while this outward focus is important and necessary, there is also a need to focus on preparing graduates for cultural issues that will arise much closer to home. Identifying, and working with subtle cultural differences that can occur in workplaces, organizations and the community, where the population may initially appear monocultural, presents unique challenges. The way in which one assumes cultural uniformity in a given situation can contribute to the oversimplification of a problem, and subsequently the pursuit of ineffective solutions. In …

Understanding Indigenous Consultation And Engagement In Engineering Education, Thomas Goldfinch, Jade Kennedy
Faculty of Engineering and Information Sciences - Papers: Part A
BACKGROUND Higher education participation rates among Aboriginal and Torres Strait Islander people are significantly lower than for other Australians (Behrendt, Larkin, Griew, & Kelly, 2012). In addition, Indigenous Australian participation rates in engineering and other technology related fields are lower than for other fields such as law, health and education (DEEWR, 2008). This presents a substantial challenge for engineering education to increase participation rates among Indigenous Australians towards those of other Australians. Engineering schools and Industry have responded with an array of outreach, scholarship, and support programs which have taken small steps towards this (BHP Billiton, 2012; EAA, 2013; Rio …

Faculty of Engineering and Information Sciences - Papers: Part A
This chapter presents a background in cognitive processes such as problem-solving and analogical reasoning for considering modelling from an object-oriented perspective within the domain of requirements engineering. This chapter then describes a research project and the findings from a set of four cases which examine professional practice from perspective of cognitive modelling for object-oriented requirements engineering. In these studies, it was found that the analysts routinely built models in their minds and refined them before committing them to paper or communicating these models to others. The studies also showed that object-oriented analysts depend on analogical reasoning where they use past …
Ethics In Engineering: Student Perceptions And Their Professional Identity Development, Brad Stappenbelt
Ethics In Engineering: Student Perceptions And Their Professional Identity Development, Brad Stappenbelt
Faculty of Engineering and Information Sciences - Papers: Part A
Professional ethics instruction in engineering is commonly conducted by examining case studies in light of the code of conduct of a suitable professional body. Although graphical presentations of spectacular failures, sobering stories of the repercussions and the solid framework provided by the tenets of a code of ethics may leave a lasting impression, students generally gain their professional identity from relatives and colleagues. Their professional ethics tend to be mostly an extension of their personal ethics. Instruction on ethics generally serves only to reinforce students' inclination to act ethically and provides encouragement to act on these beliefs. In this study …
