We propose to use objects as closures for behavior parameterization. In contrast to reuse by inheritance, they realize reuse by composition. Closures allow black-box behavior parameterization with encapsulated components, promote function reuse, allow calculations on demand, represent first-class behavior, i.e., feature protocol-, undo-, and persistence mechanisms, and can represent “businesstr...

In 1990, about 800,000 persons receiving payments from the Supplemental Security Income (SSI) program had their cases closed and their payments stopped. The most frequently cited reasons for these case closures were excess income and death. Of those cases closed for reasons other than death, about 43 percent eventually returned to payment status. This study presents an analysis of a 1-percent s...

Since 2008, government funding of the Health Service Executive (HSE) has decreased significantly. Our hospital, Cork University Hospital (CUH), implemented "cost saving" measures including scheduled operating theatre closures. We studied their affect on urological surgical activity at the hospital. A retrospective review was performed using theatre log books and theatre records to determine the...

Emergency visits are rising nationally, whereas the number of emergency departments is shrinking. However, volume has not increased uniformly at all emergency departments. It is unclear what factors account for this variability in emergency volume growth rates. The objective of this study was to test the association of hospital and population characteristics and the effect of hospital closures ...

Closure systems for personnel protection applications, such as protective clothing or respirator face seals, should provide effective permeation barrier to toxic gases. Currently available mechanical closure systems based on the hook and loop types (example, Velcro) do not provide adequate barrier to gas permeation. To achieve hermetic sealing, we propose a nonmechanical, nanoscopic molecular c...

Between 1 July 1970 and April 1971, in many hospitals in this country, there were outbreaks of nosocomial septicemia caused by Enterobacter cloacae of E. agglomerans (formerly Erwinia, herbicola-lathyri). All of these hospitals used infusion products manufactured by one company, Abbott Laboratories, and all affected patients had onset of septicemia while receiving the company's infusion product...

Rewriting is a computational process in which one term is derived from another by replacing a subterm with another subterm in accordance with a set of rules. If such a set of rules rewrite system has the property that no derivation can continue indeenitely, it is said to be terminating. Showing termination is an important component of theorem proving and of great interest in programming languag...
