Education For All

Thousands of books and articles have been written about survey methodology, but in case you don’t have hours to devote to becoming a guru, here are ten best practices to consider when building and distributing your survey. 1. Make Sure That Every Question Is Necessary You’re building your survey to obtain important insights, so every question in the survey should play a direct part. It’s best to plan your survey by first identifying the data you need to collect and  then  writing your questions. 2. Keep it Short and Simple Respondents are less likely to complete long surveys, or surveys that bounce around haphazardly from topic to topic. Therefore, make sure your survey follows a logical order and that it takes a reasonable amount of time to complete. 3. Ask Direct Questions Vague or poorly worded questions confuse respondents and make your data less useful. Strive for  clear and precise language  that will make your questions easy to answer...

Drug kinetics after multiple dosing Pharmacokinetics of multiple dose •      The purpose of the multiple dosing is to maintain a desired plasma level of drugs for long periods of time. •      The plasma level obtained from each succeeding dose is always higher than those obtained from the previous dose since some drug remains in the plasma when repeated doses are administered. • Since the rate of elimination is proportional to the amount of drug in the body, it increases with the increasing amount of drug until it approaches the rate of input (rate of input=rate of output). • At this point the amount reaches a plateau in the body. (Rate of input=rate of output). •      The main difference is the fluctuation in the plasma concentration due to multiple dosing. 2 •               Dosage regimen: – size of the drug dose – frequency o...
