Spin-Transfer Torque Magnetic Random Access Memory (STT-MRAM) is a promising emerging memory technology for on-chip caches. It has low read access time and leakage power. Unfortunately, however, STT-MRAM suffers from its long write latency high energy consumption. This paper proposes cache management technique called Proactive Invalidation (PROI) that proactively invalidates dead blocks in adva...

The sustainable management of coastal natural resources inevitably involves identifying stakeholder conflicts and developing planning processes that prevent these conflicts from becoming intractable disputes. This study links environmental conflict to specific areas within a large ecological system. Specifically, we use Geographic Information Systems (GIS) to map potentially competing stakehold...

BACKGROUND Emerging environmental pressures resulting from climate change and globalization challenge the capacity of health information systems (HIS) in the Pacific to inform future policy and public health interventions. Ciguatera, a globally common marine food-borne illness, is used here to illustrate specific HIS challenges in the Pacific and how these might be overcome proactively to meet ...

The Semantic Web has opened new horizons in exploring Web functionality. One of the many challenges is to proactively support the reuse of digital artifacts stored in repositories all over the world. Our goal is to contribute towards this issue, proposing a mechanism for describing and discovering artifacts called Digital Content Components (DCCs). DCCs are self-contained stored entities that m...

Climate change and mitigation policies adopted by a locality indelibly impact urban form, landscape, and economy. The Cities for Climate Protection (CCP) has become a dominant movement organizing the localities to proactively address climate change. This study examines metropolitan area commitment to the CCP. Geographic information systems (GIS) and statistical techniques are used to analyze me...

This paper reports on the development of a wearable system using wireless biomedical sensors for ubiquitous healthcare service provisioning. The prototype system is developed to address current healthcare challenges such as increasing cost of services, inability to access diverse services, low quality services and increasing population of elderly as experienced globally. The biomedical sensors ...

Unsolicited commercial emails (UCE, spam) are currently being fought using reactive methods, filtering being the most common. Reacting means to be always one step behind. So the focus on fighting spam should be on prevention. Current proposals focus on fixing SMTP's lack of authentication, but introduce two major problems: First of all current attempts break existing functionality and, second, ...

These words, spoken in 1867 by the British Prime Minister Benjamin Disraeli, can equally apply to components of the broader society in the 21st Century. The observation is particularly appropriate for health information management and for the theme of this issue of the Journal (the changing health information service [HIS] work environment) and reflected in many of the papers included in the Is...
