37 We discuss behavioral studies directed at understanding how probability 38 information is represented in motor and economic tasks. By formulating the behavioral 39 tasks in the language of statistical decision theory, we can compare performance in 40 equivalent tasks in different domains. Subjects in traditional economic decision-making 41 tasks often misrepresent the probability of rare eve...

There are problems with the adoption and use of many organizational implementations of Web-Based Education (WBE). This paper puts forward the view that the problems stem from a misfit between the development methodologies commonly used to implement these systems and the context in which they are being applied. This misfit contributes to a number of the problems and shortcomings faced with imple...

• In many areas of application, a typical requirement is to estimate a high quantile χ1−p of probability 1−p, a value, high enough, so that the chance of an exceedance of that value is equal to p, small. The semi-parametric estimation of high quantiles depends not only on the estimation of the tail index γ, the primary parameter of extreme events, but also on an adequate estimation of a scale f...

stressful life events may play an important role in coronary heart disease and sudden cardiac death. this study was performed to compare the frequency of stressful events and mental strain in patients with acute myocardial infarction (mi) and normal population. a case-control study was performed on 50 survivors of mi and 50 controls with no evidence of cardiovascular disease, matched by age, ge...

To a great extent, the usefulness of a formal model of a software process lies in its ability to accurately predict the behavior of the executing process. Similarly, the usefulness of an executing process lies largely in its ability to fullll the requirements embodied in a formal model of the process. When process models and process executions diverge, something signiicant is happening. We are ...

Shiraz, with its historical background, known as the capital of the Persian culture, once experienced a boom of international culture-led events using outdoor spaces as event venues. However, its outdoor vibrancy has withered gradually, and the use of public places as venues declined. Despite the existing dilemmas, a new wave of public place reclamation has created a strong trend towards using ...

AbstractObjectives: Understanding the nature and types of stressful events in life of school age children. Method: In this qualitative study, using an open interview, the description of stressful life events by 29 schoolchildren in Tabriz, Iran, were recorded and analyzed. Results: 223 stressful events derived from the interviews, were classified into 17 basic categories. In the end, four theme...

  We report on an experimental comparison of the characteristics of quark-induced jets based on an analysis of jet events selected from hadronic events at c.m. energy of 60 GeV in e+e- annihilations. The triangle plot shows that the majority are two-jet events. The three-jet events are also present but not as many as two-jet events. The mean transverse momentum is larger for three-jet events th...

After extreme events such as floods, thunderstorms, blizzards and hurricanes there will be devastating effects in the distribution networks which may cause a partial or complete blackout. Then, the major concern for the system operators is to restore the maximum critical loads as soon as possible by available generation units.  In order to solve this problem, this paper provides a restoration s...
