Rheumatoid cachexia: what is it and why is it important?

Radiogenomics: what it is and why it is important.

In recent years, a new direction in cancer research has emerged that focuses on the relationship between imaging phenotypes and genomics. This direction is referred to as radiogenomics or imaging genomics. The question that subsequently arises is: What is the practical significance of elucidating this relationship in improving cancer patient outcomes. In this article, I address this question. A...

Wearable electroencephalography. What is it, why is it needed, and what does it entail?

The electroencephalogram (EEG) is a classic noninvasive method for measuring a person's brain waves and is used in a large number of fields: from epilepsy and sleep disorder diagnosis to brain-computer interfaces (BCIs). Electrodes are placed on the scalp to detect the microvolt-sized signals that result from synchronized neuronal activity within the brain. Current long-term EEG monitoring is g...

Workpractice Theory – What it is and Why we need it

This is an introduction to the panel “Workpractice Theory as Foundation for IS Research” on the ALOIS*2005 conference. It is also a position statement concerning workpractice theory. It describes the needs for a workpractice theory in information systems research. It describes briefly also the workpractice theory developed by Goldkuhl & Röstlinger. This is an example of a workpractice theory to...

Teacher agency: what is it and why does it matter?

The concept of teacher agency has emerged in recent literature as an alternative means of understanding how teachers might enact practice and engage with policy (e.g. Lasky, 2005; Leander & Osbourne, 2008; Ketelaar et al., 2012; Priestley, Biesta & Robinson, 2013).
