The Hawkesbury-Nepean River (HNR) system in South-Eastern Australia is the main source of water supply for the Sydney Metropolitan area and is one of the more complex river systems due to the influence of urbanisation and other activities in the peri-urban landscape through which it flows. The long-term monitoring of river water quality is likely to suffer from data gaps due to funding cuts, ch...

Social and cognitive psychology frames have dominated IS researchers’ attention in developing and applying theory to explain human behavior in the context of IS. However with a few exceptions, the information systems literature has largely ignored the possible explanatory power of evolutionary psychology. This is a major omission, particularly as Darwin argued that perception and cognition, are...

Organisations are faced with a number of challenges and issues in decentralised, multiple-server, physical, non-virtualized IT environments. Virtualization in recent years has had a significant impact on computing environments and has introduced benefits, including server consolidation, server and hardware utilization and reduced costs. Virtualization’s popularity has led to its growth in many ...

For a researcher in a field with high industrial relevance, retrieving and analyzing research papers and patents have become an important aspect of assessing the scope of the field. We propose a method for creating a technical trend map automatically from both research papers and patents. For the construction of the technical trend map, we focus on the elemental (underlying) technologies used i...

BACKGROUND Appropriate hand hygiene among health care workers is the most important infection prevention measure; however, compliance is generally low. Gain-framed messages (ie, messages that emphasize the benefits of hand hygiene rather than the risks of noncompliance) may be most effective, but have not been tested. METHODS The study was conducted in a 27-bed neonatal intensive care unit. W...

C-TREND: A New Technique for Identifying and Visualizing Trends in Transactional Data Gediminas Adomavicius, Jesse Bockstedt Department of Information and Decision Sciences Carlson School of Management University of Minnesota { [email protected], [email protected] } Last Modified: February 1, 2007 Abstract. We introduce C-TREND, a new temporal data analysis and visualization technique for rep...

The problem of estimating underlying trends in time series data arises in a variety of disciplines. In this paper we propose a variation on Hodrick–Prescott (H-P) filtering, a widely used method for trend estimation. The proposed !1 trend filtering method substitutes a sum of absolute values (i.e., !1 norm) for the sum of squares used in H-P filtering to penalize variations in the estimated tre...

Much research studies US inflation history with a trend-cycle model with unobserved components. A key feature of this model is that the trend may be viewed as the Fed’s evolving inflation target or long-horizon expected inflation. We provide a new way to measure the slowly evolving trend and the cycle (or inflation gap), based on forecasts from the Survey of Professional Forecasters. These fore...
