BACKGROUND Recent research has shown evidence of disproportionate time allocation for patient communication during multidisciplinary rounds (MDRs). Studies have shown that patients discussed later during rounds receive lesser time. OBJECTIVE The aim of our study was to investigate whether disproportionate time allocation effects persist with the use of structured rounding tools. METHODS Usi...

OBJECTIVE We developed a theoretically based taxonomy for classifying shared cognition breakdowns related to teamwork which contribute to fratricide incidents. BACKGROUND Fratricide on the battlefield is an inescapable cost of war. A number of technological advancements have been made in terms of combat identification systems to reduce the risk of these incidents. However, fratricide continue...

The LL anczos method for solving systems of linear equations is based on formal orthogonal polynomi-als. Its implementation is realized via some recurrence relationships between polynomials of a family of orthogonal polynomials or between those of two adjacent families of orthogonal polynomials. A division by zero can occur in such recurrence relations, thus causing a breakdown in the algorithm...

A descriptive analysis, to investigate the potential risk factors that might have contributed to the increased incidence of bovine tuberculosis (BTB) herd-breakdowns in the reference area of Co. Donegal during the fifth year of the four-area project (FAP), was performed. Seventy two different herds were restricted for BTB during the FAP; 10 of these herds were restricted twice, resulting in a t...

This paper deals with the performance analysis of multiple server retrial queueing systems with a finite number of homogeneous sources of calls, where the heterogeneous servers are subject to random breakdowns and repairs. The requests are serviced according to Random Selection and Fastest Free Server disciplines. The novelty of this investigation is the introduction of different service rates ...

This paper analyzes the portfolio decision of an investor facing the threat of illiquidity. In a continuous-time setting, the efficiency loss due to illiquidity is addressed and quantified. For a logarithmic investor, we solve the portfolio problem explicitly. We show that the efficiency loss for a logarithmic investor with 30 years until the investment horizon is a significant 22.7% of current...

In this paper, we apply and compare two generalized estimating equation approaches to the analysis of car breakdowns data in Mauritius. Number of breakdowns experienced by a machinery is a highly under-dispersed count random variable and its value can be attributed to the factors related to the mechanical input and output of that machinery. Analyzing such under-dispersed count observation as a ...

This paper analyzes an M/M/2 queueing system with two heterogeneous servers. Both servers goes on vacation when there is no customers waiting for service after this server 1 is always available but the other goes on vacation whenever server 2 is idle. The vacationing server however, returns to serve at a low rate as an arrival finds the other server busy. The system is analyzed in the steady st...

Services play a vital role in economies of nations and in world commerce. An economy cannot operate without the services provided by service firms. In its turn, a service firm cannot survive without a sound competitive strategy. Management of service systems is a continuous challenge, due to the dynamic and random nature of the service environment. The theory of waiting lines provides insight a...
