background: we presumed that the surgeon himself has an impact on the results after coronary artery bypass grafting (cabg) as there is no unique protocol for the discharge of post-operative cardiac patients at our institution. therefore, we examined whether the surgeon himself has an impact on the intensive care unit (icu) stay of isolated cabg patients. methods: we prospectively studied a tota...

the aim of present study was to determine the impact of two different icu management model, open and semi closed, on resources utilization in intensive care unit.retrospective cohort analysis using data from hospital database was applied to compare the effect of icu management model on icu length of stay and bed disposition of 1064 patients admitted to the general icu of imam khomeini hospital ...

background: asthma is a common condition in general medical practice, and it accounts for about 1% of all ambulatory hospital visits. nowadays, hospitalization rates for asthma have actually been increased in some demographic subgroups despite recent advances in treatment. understanding the underlying factors that contribute to hospitalization and especially duration of the hospitalization of a...

Industrial ecology has mainly been concerned with improving the efficiency of production systems. But addressing consumption is also vital in reducing the impact of society on its environment. The concept of sustainable consumption is a response to this. But the debates about sustainable consumption can only really be understood in the context of much wider and deeper debates about consumption ...

BACKGROUND Early discharge after childbirth is widely reported. In this study the authors examined trends in maternal length of hospital stay in Canada from fiscal year 1984-85 through fiscal year 1994-95. They also examined variations in length of stay in 1994-95 in most of the Canadian provinces and the territories. METHODS Epidemiologic analyses of the temporal and geographic variations in...

This paper describes a method that predicts which trades players execute during a winlose game. Our method uses data collected from chat negotiations of the game The Settlers of Catan and exploits the conversation to construct dynamically a partial model of each player’s preferences. This in turn yields equilibrium trading moves via principles from game theory. We compare our method against fou...

In this paper we study a simple learning paradigm for iterated normal form games in an evolutionary context. Following the decision theoretic concept of satisscing we design players with a certain aspiration level. If their payoo is below this level, they change their current action, otherwise they repeat it. We consider stochastic generalizations of this win stay { lose shift principle that av...
