BACKGROUND Using a large cohort of western Canadian sawmill workers (n = 28,794), the association between psychosocial work conditions and attempted and completed suicide was investigated. METHODS Records of attempted and completed suicide were accessed through a provincial hospital discharge registry to identify cases that were then matched using a nested case control method. Psychosocial wo...

With the growth in customers’ demand diversification, mixed-model U-lines (MMUL) have acquired increasing importance in the area of assembly systems. There are generally two different approaches in the literature for balancing such systems. Some researchers believe that since the types of models can be very diverse, a balancing approach without simultaneously sequencing of models will not yield...

The so-called P ¤ model is frequently used or referred to in discussions of monetary targeting. This gives the impression that the P ¤ model might provide some rationale for monetary targeting or for the monetary reference value used by the Eurosystem. The P ¤ model implies that in‡ation is determined by the level of and changes in the “real money gap” (the deviation of current real balances fr...

TCP was designed for wired networks and the sender assumes that packet loss is an indicator of network congestion, but this assumption may not apply to Mobile Ad hoc Networks (MANETs). In Mobile Ad Hoc networks, performance of the standard TCP is significantly degraded due to characteristics of MANET such as route failures due to node mobility and link errors. In this paper, the authors investi...

It is an essential demand to establish an effective financial risk early-warning system for financial security. But some factors have a lagging effect on financial risk. So this paper aims to construct a reasonable and practical indicator system for financial risk early-warning. First, determine the explained variables of the indicator made up by Chinese financial stress index. Second, confirm ...

Industrial systems require reliable components. The interactions among components affect the system reliability. In this study, the electrical power system Robustness is evaluated among its sensitivity to potential changes in the intrinsic parameters. Reliability represents a state indicator. In this work, highlights are made on the importance of Maintenance in Sustaining the QoS of a System. S...

Carsharing is one of the effective ways to relieve the problems of traffic jams, parking difficulties, and air pollution. In recent years, the numbers of carsharing services and their members have remarkably increased around the world. The project of electric carsharing in Shanghai, called EVCARD, has also developed rapidly with very large demand and supply. Aiming to determine the optimal loca...

erythropoietin. Transferrin saturation is a good indicator of the current balance of supply and demand of plasma iron, although it is an inadequate indicator of the amount of iron stored. In addition, Bainton and Finch showed that once the transferrin saturation falls below 16% iron supply for erythropoiesis may be inadequate.4 Our data also suggest that, during treatment with erythropoietin, m...

This paper describes sensitivity indicator method to identify weakest bus of the system. It also describes method of calculating the amount of reactive power to be injected at the load bus to avert the voltage instability as the load on the load bus increases. In this paper IEEE-57 BUS system has been considered. First, the weakest bus is identified using sensitivity indicator method. Then Load...
