Inappropriate prescribing (IP) is a common and serious global healthcare problem in elderly people, leading to increased risk of adverse drug reactions (ADRs), polypharmacy being the main risk factor for both IP and ADRs. IP in older people is highly prevalent but preventable; hence screening tools for IP have been devised, principally Beers' Criteria and the Inappropriate Prescribing in the El...

Distributed systems desire to construct a random overlay graph for robustness, efficient information dissemination and load balancing. A random walk-based overlay construction is a promising alternative to generate an ideal random scale free overlay in distributed systems. However, a simple random walk-based overlay construction can be affected by node churn. Especially, the number of edges inc...

In this study, the author describes the nature and occurrence of knowledge-construction links (KCLs) in 3 6th-grade classrooms that varied in degree of learner centeredness. KCLs are operationalized as prior learning that students bring to their current classroom experiences and include school and nonschool experiences. They are hypothesized to facilitate a knowledge-construction process that v...

We view planning as a search through a space of plan models. A plan model consists of a partial description of a course of action (a plan) and a set of decision models that support analysis of the plan. In this framework, model building is focussed on the development of techniques to support the incremental evaluation and construction of plans. There are special problems associated with plannin...

Selective induction techniques perform poorly when the features are inappropriate for the target concept. One solution is to have the learning system construct new features automatically ; unfortunately feature construction is a diicult and poorly understood problem. In this paper we present a deenition of feature construction in concept learning, and ooer a framework for its study based on fou...

This paper presents a mechanism in developing work-rest schedules for construction labors. Two objectives are balanced in the optimization processes. These objectives include minimizing the time for completing jobs as well as minimizing total extra energy that labors expend due to inappropriate work assignment which forces labors to working longer than maximum acceptable work duration. Experime...
