The SCl’s method of obtaining comprehensive coverage of the literature has its foundation in Bradford’s Law (16.17). In general, this law states that a small percentage of journals account for a large percentage of the signiEcant articles in any given field of science. In support of this, a study of Physics Abstracts by Keenan and Atherton (18) shows that 50% of the items abstracted are taken f...

In asynchronous message-passing distributed systems prone to process crashes, a communication link is said δ-timely if the communication delay on this link is bounded by some constant δ. We study here in which way processes may approximate and find structural properties based on δ-timeliness (e.g., find δ-timely paths between processes or build a ring between correct processes using only δ-time...

Primary Care and Advanced Access For most patients, their primary care physician is their major access point into the health care system. Yet primary care practices often have long waits for appointments and may have difficulty in accommodating patients who have potentially urgent problems. As a result, patients experience delays in treatment and may be seen by someone other than their own phys...

An important element of the cost of distance is time taken in delivering final and intermediate goods. We argue that time costs are qualitatively different from direct monetary costs such as freight charges. The difference arises because of uncertainty. Unsynchronised deliveries can disrupt production, and delivery time can force producers to order components before demand and cost uncertaintie...

ABSTRACT This article aimed to examine the timeliness of goodwill impairment perceived by Brazilian capital market. Despite it being widely studied internationally, has not yet been empirically investigated in Brazil, given that previous studies focus on determinants this loss, its disclosure, or manager behavior. question is relevant primarily due context standardization International Accounti...

Events generated by the execution of a distributed system are related by causality and concurrency. While providing a means of reasoning about the relative occurrence of events, this partial order fails to represent the timeliness of occurrence. In this paper, we develop a novel means of assigning weights to events where the weights are reduced as the temporal proximity to an anchor event incre...

The intrinsic properties of Wireless Sensor Networks (WSN) such as their ad-hoc infrastructure, energy constraints, and limited availability of resources, constitute an unfavorable environment for end-to-end timeliness guarantees. Many existing solutions are based on a timeliness notion borrowed from real-time systems, which can only express strict end-to-end deadlines for individual messages. ...

Correctness of a real-time system depends on its computation as well as its timeliness. In recent years, research has been focusing on verifying the correctness of a real-time system during runtime by monitoring its runtime execution and checking it against its formal specifications. Such verification method is called Runtime Verification. While a few existing runtime verification tools verify ...
