Spatiotemporal multi-resolution approximation of the Amari type neural field model
Neural fields are spatially continuous state variables described by integro-differential equations, which are well suited to describe the spatiotemporal evolution of cortical activations on multiple scales. Here we develop a multi-resolution approximation (MRA) framework for the integro-difference equation (IDE) neural field model based on semi-orthogonal cardinal B-spline wavelets. In this way, a flexible framework is created, whereby both macroscopic and microscopic behavior of the system can be represented simultaneously. State and parameter estimation is performed using the expectation maximization (EM) algorithm. A synthetic example is provided to demonstrate the framework
Domestic Violence and Health Care: Opening Pandora¿s Box ¿ Challenges and Dilemmas
In this article we take a critical stance toward the rational progressive narrative
surrounding the integration of domestic violence within health care. Whilst changes in
recent UK policy and practice have resulted in several tangible benefits, it is argued that
there may be hidden dilemmas and challenges. We suggest that the medical model of care
and its discursive practices position women as individually accountable for domestic
violence-related symptoms and injuries. This may not only be ineffective in terms of
service provision but could also have the potential to reduce the political significance of
domestic violence as an issue of concern for all women. Furthermore, it is argued that the
use of specific metaphors enables practitioners to distance themselves from interactions
that may prove to be less comfortable and provide less than certain outcomes. Our analysis
explores the possibilities for change that might currently be available. This would
appear to involve a consideration of alternative discourses and the reformulation of power
relations and subject positions in health care
