conclusions considering that the most frequent reason for our urvs was patient-related factors, where all cases had left the cpu against medical advice (ama) during their first attendance, we recommend that further appropriate strategies be devised to prevent leaving against medical advice. results patient-related factors accounted for most 72 hours urvs (49%). multivariable analysis revealed t...

To support the effort to eliminate the Syrian Arab Republic chemical weapons stockpile safely, there was a requirement to provide scientific advice based on experimentally derived information on both toxicity and medical countermeasures (MedCM) in the event of exposure to VM, VX or VM-VX mixtures. Complementary in vitro and in vivo studies were undertaken to inform that advice. The penetration ...

The authors review the work of the previous Scientific Committee on Animal Health and Animal Welfare and the current European Food Safety Authority (EFSA) in providing scientific advice on the welfare aspects of animal transport and the impact of this advice on the European Union (EU) regulatory framework. Through its Protocol on the Protection and Welfare of Animals, the Treaty of Amsterdam ob...

We consider systems composed of a base system with multiple “features” or “controllers”, each of which independently advise the system on how to react to input events so as to conform to their individual specifications. We propose a methodology for developing such systems in a way that guarantees the “maximal” use of each feature. The methodology is based on the notion of “conflict-tolerant” fe...

Cumulative abnormal return (CAR) is estimated as long-term shareholder wealth of private placement, and we propose empirical evidence of the effect of private placement on long-term shareholder wealth. Private placement of listed firms has significantly positive effect on long-term shareholder wealth. Cumulative abnormal return are positively related with offer type of private placement at the ...

This paper represents a paradigm shift in what advice agents should provide people. Contrary to what was previously thought, we empirically show that agents that dispense optimal advice will not necessary facilitate the best improvement in people’s strategies. Instead, we claim that agents should at times suboptimally advise. We provide results demonstrating the effectiveness of a suboptimal ad...

Learning Communities is one approach in individuals to improve their skills and knowledge. Web based learning communities provide additional capabilities such as global distribution of participants and asynchronous participation. The learning process in such communities is flexible and distributed, but still uni-directional: knowledge, advices and support is transferred from professors to stude...

There is much interest in how to ensure that the results obtained from a simulation model are accurate. This paper considers this from the perspective of three main sources of inaccuracy: the modelling, the data and the experimentation. For each of these sources the causes of inaccuracy are discussed and some advice is given on how to overcome them. An illustrative model is used to quantify som...

Over the past decade, many profit-seeking technology firms voluntarily made their proprietary software open-source. In this paper, we study firm’s motivation of such voluntary open-source and its implications. Through analyzing the tradeoff between supply-side externality and demand-side appropriability, we identify the conditions under which firms will voluntarily open source. Our result highl...
