Imaging the brain: visualising “pathological entities”? Searching for reliable protocols within psychiatry and their impact on the understanding of psychiatric diseases

Given that visualisations via medical imaging have tremendously increased over the last decades, the overall presence of colour-coded brain slices generated on the basis of functional imaging, i.e. neuroimaging techniques, have led to the assumption of so-called “kinds” of brains or cognitive profiles that might be especially related to “non-healthy” humans affected by neurological, neuropsychological or psychiatric syndromes or disorders. In clinical contexts especially, one must consider that visualisations through medical imaging are suggestive in a twofold way. Imaging data not only visually render pathological entities, but also tend to represent objective and concrete evidence for these psychophysical states in question. This article aims to identify key issues in visually rendering psychiatric disorders via functional approaches of imaging within the neurosciences from an epistemological point of view.     

A noise estimation method for corrupted correlated data

Data acquisition, both in time and in spatial domains, in many cases yields observations with a measurement error. The identification of such a component, that masks the phenomenon under study (signal), must be carried out before the model of interest is specified. The objective of the paper is to propose an estimator for the parameters of an additive noise and compare it with existing methods by applications to both simulated and real data sets.     

Practices of Engagement: Comparing and Integrating Deliberation and Organizing

The purpose of this article is to provide a comparison of institution-based community organizing and deliberative practices and to demonstrate how these are complementary approaches for civic engagement. In contrast to older typologies describing these two approaches oppositionally, we seek to reveal a shared democratic ethos and propose greater collaboration between action-oriented organizers and deliberative advocates. The article also identifies where deliberative and organizing practices diverge and proposes a model for how the two approaches can be integrated for mutual benefit.
