In this paper, we attempt to invent a new way to understand risk, measure it, and weigh its consequences. We attempt to design a rational process for risk-taking; a process that gives the system dynamicist the ability to define what may happen in the future and then to choose among alternatives. The two conventional ways to use optimization in system dynamics models are historical data fitting ...

Assessments are common in undergraduate classrooms, with formats including multiple-choice and open-ended (in which the students must generate their own answers) questions. While much is known abou...

INTRODUCTION The inefficacy of clinical skill education during the clerkship has been reported in several studies. The present study was conducted to evaluate the competency of medical students in performing several clinical skills through an Objective Structured Clinical Examination (OSCE), aiming to evaluate the quality of the existing curriculum in the clerkship phase. MATERIAL AND METHODS...

Background: Tincture of opium (TOP) is currently used for maintenance therapy in treatment of opioids addiction. It contains ethanol. The present study was conducted to assess the increase in blood alcohol concentration (BAC) in its users; a process which may interfere with breath-alcohol test performed by law enforcement or traffic police. Methods: A total of 143 individuals were selected rand...

Psychology (ABSTRACT) This study examined test-taking attitudes and response distortion on a personality test. Consistent with our hypotheses, applicants were found to have significantly more positive test-taking attitudes and exhibit a greater degree of response distortion as compared to incumbents. In addition, test-taking attitudes were significantly associated with response distortion. Howe...

The random generation of coherent solitary waves from incoherent waves in a medium with an instantaneous nonlinearity has been observed. One excites a propagating incoherent spin wave packet in a magnetic film strip and observes the random appearance of solitary wave pulses. These pulses are as coherent as traditional solitary waves, but with random timing and a random peak amplitude.

A trial is reported in which RAMC staff working in a dressing station and wearing full NBC Individual Protective Equipment (IPE), attempted to take pulse and blood pressure (BP) readings on casualties similarly clad. These basic parameters however, were obtained from only half the casualties, the time taken to obtain them was prohibitive and the blood pressures were inaccurate. Certain remedies...
