An Introduction to Natural Experiment Studies

در دو سخن سردبیری شماره‌های قبل به مطالعات مداخله‌ای (Interventional and/or experimental studies) [1] و مطالعات نیمه تجربی (studies Quasi-experiment) [2] پرداختیم. همان جا، به این نکته اشاره کردیم که برای اندازه‌گیری کارآیی یک دارو، واکسن، برنامه بهداشت عمومی و متغیرهای دیگری از این دست، مطالعات مداخله‌ای بهترین گزینه هستند. تقسیم تصادفی و کورسازی از مؤلفه‌های اساسی یک مطالعه مداخله‌ای است [1]....

Introduction Jonathan McElroy November 6 , 2009

One of the main goals of Computer Science is to increase the ease of HumanComputer Interaction by creating systems that assist users by allowing them to perform tasks more intuitively. With the rate of computers complexity, speed and disk space have increased continuously in recent years combined with the increase in usage of digital documents, there has been a greater increase in the desire to...

For example Professor Paul Crutzen, who was awarded a Nobel Prize for his work in atmospheric chemistry, was actually an engineer and meteorologist by training. Many people working in the broad area of environmental chemistry are physicists,...

Genetic association studies test for a correlation between disease status and genetic variation to identify candidate genes or genome regions that contribute to a specific disease. A higher frequency of a singlenucleotide polymorphism (SNP) allele or genotype in a series of individuals affected with a disease can be interpreted as meaning that the tested variant increases the risk of a specific...
