Adaptability in organisms and artifacts: A multi level perspective on adaptive processes

Abstract Adaptability to changing circumstances is a key feature of living creatures. Understanding such adaptive processes is central to developing successful autonomous artifacts. In this paper two perspectives are brought to bear on the issue of adaptability. The first is a short term perspective which looks at adaptability in terms of the interactions between the agent and the environment. The second perspective involves a hierarchical evolutionary model which seeks to identify higher-order forms of adaptability based on the concept of adaptive meta-constructs. Task orientated and agent-centered models of adaptive processes in artifacts are considered from these two perspectives. The former isrepresented by the fitness function approach found in evolutionary learning, and the latter in terms of the concepts of empowerment and homeokinesis found in models derived from the self-organizing systems approach. A meta-construct approach to adaptability based on the identification of higher level meta-metrics is also outlined. 2009 Published by Elsevier B.V.

Masks as self-study. Challenging and sustaining teachers’ personal and professional personae in early–mid career life phases

Drawing on previous research identifying how teachers’ capacities to sustain their effectiveness in different phases of their professional lives are affected positively and/or negatively by their sense of identity, this paper illuminates three early–mid career teachers’ self-study inquiries, centring on mask work. The creative development of individual masks discloses teachers’ complex, occasionally
dislocated narratives of personal/professional identity. Subsequent improvisation with their masks is shown to engage teachers emotionally with tensions and dissonances within and between their various personae and personal, professional and political contexts at each of their respective career life phases. Storylines ultimately become reframed and, in a number of instances, lay claim to reinvigorated commitment, self-determination and initiatives for change.
