On Necessary and Sufficient Conditions for Preserving Convergence Rates to Equilibrium in Deterministically and Stochastically Perturbed Differential Equations with Regularly Varying Nonlinearity
This paper develops necessary and sufficient conditions for the preservation
of asymptotic convergence rates of deterministically and stochastically
perturbed ordinary differential equations with regularly varying nonlinearity
close to their equilibrium. Sharp conditions are also established which
preserve the asymptotic behaviour of the derivative of the underlying
unperturbed equation. Finally, necessary and sufficient conditions are
established which enable finite difference approximations to the derivative in
the stochastic equation to preserve the asymptotic behaviour of the derivative
of the unperturbed equation, even though the solution of the stochastic
equation is nowhere differentiable, almost surely
The nature of practitioner research: critical distance, power and ethics
Researching within one’s place of practice allows the researcher to have the unique position of knowing the participants and the research context. The relationship the participants have with the researcher will impact upon the disclosure of information differently than research conducted by someone outside the area of practice. This can be a benefit and a drawback for the participants, the area of practice and the researcher. However, as is demonstrated within this paper, the role the researcher adopts throughout the process of gathering information is not always clear. As a student on the Doctorate of Education programme myself, the nature of practitioner research and the complexities of this type of research is of great interest to me. Beginning to develop my own research project through this taught programme has allowed an opportunity to think through these challenges and wrestle with the complexity and contradiction, dilemma and incongruity which emerges from being a researching practitioner. Within this piece it is suggested that these quandaries can be considered from the perspective of critical distance, relationships and power and ethical considerations. The idea of considering these conflicts reflexively will be explored here. Although this discussion was not based on empirical research findings as such, it is anticipated that this piece will further the understanding of practitioner research in higher education from the position of being a student and through scholastic analysis of the Ed D programme providing a particular perspective on the nature of research
Using change management theory to implement the international classification of functioning, disability and health (ICF) in clinical practice
Practice Evaluation
The success of the International Classification of Functioning, Disability and
Health (ICF) depends on its implementation in practice. This article describes
an evaluation of the introduction of the ICF framework into an occupational
therapy service. Reflections from the working party responsible for its
introduction were related to change management theory. The experiences
throughout the implementation project could be mapped to an eight-stage
process of creating major change (Kotter 1996). The working party concluded
that the explicit use of and closer adherence to change management theory
could enhance the uptake of the ICF in clinical practice. Further exploratory
research is required to support these reflections
Quantum Errors and Disturbances: Response to Busch, Lahti and Werner
Busch, Lahti and Werner (BLW) have recently criticized the operator approach
to the description of quantum errors and disturbances. Their criticisms are
justified to the extent that the physical meaning of the operator definitions
has not hitherto been adequately explained. We rectify that omission. We then
examine BLW's criticisms in the light of our analysis. We argue that, although
the approach BLW favour (based on the Wasserstein 2-deviation) has its uses,
there are important physical situations where an operator approach is
preferable. We also discuss the reason why the error-disturbance relation is
still giving rise to controversies almost a century after Heisenberg first
stated his microscope argument. We argue that the source of the difficulties is
the problem of interpretation, which is not so wholly disconnected from
experimental practicalities as is sometimes supposed.Comment: AMS latex, 29 page
