heart failure is common in patients with chronic renal disease, either as a complication of renal failure or from shared risk factors, or is the major cause of death in patients on dialysis. at present, end stage renal disease (esrd) patients who have systolic heart failure are considered high-risk for surgery; and nephrologists and cardiologists are reluctant to refer these patients for kidney...

The Initial Screening Tool (IST) has been developed to enable Planners to assess the potential risk to ground and surface water due to remobilisation of contaminants by new developments. The IST is a custom built GIS application that improves upon previous screening tools developed by the British Geological Survey (BGS) through the inclusion of 3-D geological data and an enhanced scoring method...

Imagine the economy and society of a completely digitized media world in 2015. To predict such a world is difficult or rather impossible. Peer-to-peer systems such as Kazaa give an impression of how fast millions of users are able to threaten conventional ways of distribution and inflexible royalty systems. Traditional forecast methods cannot cope with such fast changing and highly uncertain en...

Color is undeniably important to object representations, but so too is the ability of context to alter the color of an object. This study examined whether canonical knowledge about typical color or contextual knowledge about scenario-specific color plays a central role in object representation. Participants performed a modified Stroop task that asked them to name the color of a target word (typ...

The operational environment of the Information and Communication Technology (ICT) industry is in continuous change due to factors like rapid technological development, uncertain economic development and unpredictable consumer behaviour. Consequently, also the skills needed in the ICT industry are changing. Therefore, the quantitative and qualitative demand of ICT professionals in the future is ...

Agency theory has long been a stalwart of IS research and is one of the most commonly used lenses to study the relationship between a principal and an agent. The Theory of Relationship Constraints (TRC) has recently been recommended as an informationoriented alternative to agency theory. TRC suggests that three attributes (i.e., the level of information asymmetry, levels of tacit and explicit k...

This paper discusses a methodological framework for systems thinking and modelling interventions. The methodology includes five major phases: problem structuring; causal loop modelling; dynamic modelling; scenario planning and modelling; and implementation and organisational learning. These phases each involve a number of steps. However, each systems intervention does not require all the phases...
