The improvement of healthcare quality and patient safety is at its heart a social act. I am particularly aware of this each year when I attend the International Forum on Quality and Safety in Health Care. In March 2009 in Berlin, I spent one of the most pleasurable evenings I can remember in a restaurant with colleagues from the UK, Sweden, Spain, Australia, Netherlands, Italy and the USA—a gro...

safety issues have always been put forward as one of the major problems and primary concerns in construction industries in many countries. this paper will focus on the impact of safety training on safety climate and its relevant factors in two sites of a construction firm. the health and safety executive (hse) guide to safety climate tool that had been validated in iran was used to determine th...

in this paper, efforts are made to compare the safety of steel moment resistant frames designed according to different editions of the iranian code of practice for seismic resistant design of buildings. also, failure risk of a low and medium height frame which designed for high and low seismicity regions according to three editions of the code are evaluated. first, the testing cases were design...

We study a stochastic lead-time problem motivated by real world global shipping data. Replenishment quantities are generated by the Order-Up-To policy which aims to achieve a strategic availability target. We show that unlike the constant lead-time case, minimum safety stocks do not always lead to minimum costs under stochastic lead-times.

Recent models with liquidity constraints and impatience emphasize that consumers use savings to buffer income fluctuations. When wealth is below an optimal target, consumers try to increase their buffer stock of wealth by saving more, while, if wealth is above target, they increase consumption. This important implication of the buffer stock model of saving has not been subject to direct empiric...

The goal of this study was to carry out singleand multi-aspect ABC analyses in spare parts warehouse. Two cases were considered within the investigations. First case concerned stock with the required safety stock, whereas in the second case, safety stock was neglected. Comparison of the results for both analyses was to show how the level of safety stock impacts on selection of more profitable a...

We describe an implementation of an Oberon0 compiler using the techniques proposed in the CoCoCo project. The compiler is constructed out of a collection of pre-compiled, statically type-checked language-definition fragments written in Haskell.

This paper extends the idea of co-types (described in a companion paper) to include the concept of adjustment hierarchies. An adjustment hierarchy provides a parallel hierarchy to a subtyping hierarchy of a type being expanded by the co-type. This has a number of advantages including the predefinition of co-types for subtypes of an expanded type, and allowing automatic covariant adjustment of p...

We have constructed an explanation system for polymorphic types, motivated by analysis of human type explanations. Qualitative and quantitative comparison of human expert and our computer generated explanations of polymorphic type errors suggests that they are very similar.
