Miller (1956) summarized evidence that people can remember about seven chunks in short-term memory (STM) tasks. However, that number was meant more as a rough estimate and a rhetorical device than as a real capacity limit. Others have since suggested that there is a more precise capacity limit, but that it is only three to five chunks. The present target article brings together a wide variety o...

There are compelling similarities in the caregiving functions of good clinicians and good parents. Both clinicians and parents function best in a supportive environment. Yet many clinicians do not feel supported. They are under relentless pressure to find ever-briefer forms of treatment for all individuals, regardless of the individual's symptoms or circumstances. This pressure is especially di...

During long-term memory formation, cellular and molecular processes reshape how individual neurons respond to specific patterns of synaptic input. It remains poorly understood how such changes impact information processing across networks of mammalian neurons. To observe how networks encode, store, and retrieve information, neuroscientists must track the dynamics of large ensembles of individua...

Accurate estimation of link quality is the key to enable efficient routing in wireless sensor networks. Current link estimators focus mainly on identifying long-term stable links for routing, leaving out a potentiality large set of intermediate links offering significant routing progress. Fine-grained analysis of link qualities reveals that such intermediate links are bursty, i.e., stable in th...

Changes in demographics and in the operating environments of acute care hospitals have resulted in the development of new geriatric service products. Presented in this article is a framework for describing the variety of new services in terms of sponsor goals and core activities. Five broad types of geriatric service developments are described: geriatric medical care, post-acute care, transitio...

The purpose of this column is fo discuss innovafions and quality improvement efforts in a variety of long-term care seffings. These issues are of importance to healthcare professionals, as our nation faces the burgeoning growth of the aging population, creating increased demand for improved and innovative long-term care services. This column is coordinated by Marilyn J. Rantz, PhD, RN, FAAN, NH...

consequent difficulty living independently, living in the community requires not only medical and support services, but also housing. All too often, however, housing sponsors and long-term care providers operate in isolation, leading at best to frustration on the part of individuals, who must piece together workable housing and service arrangements, and at worst to otherwise avoidable instituti...
