Alice Catherine Evans service worker was protected by law. Alice became interested in the disease brucellosis and its relationship to fresh, unpasteurized milk. Alice's investigation focused on the organism "Bacillus abortus", known to cause miscarriages in animals. Alice learned that the microbe thrived in infected cows as well as animals that appeared healthy. The reports hypothesized that since the bacteria was found in cow's milk, a threat to human health was likely. Evans decided to investigate this; she wondered whether the disease in cows could be the cause of undulant fever in humans. She reported her findings to the Society of American Bacteriologists
Conflict procedure and contingent electric foot shocks." In order to operate the experiment, researchers build anxiety by electrical shocks on rats gradually through a training in serval week. This process was what researchers called Conflict Procedure. Conflict procedure The conflict procedure is an experiment often used in scientific research to quantify anxiety levels by measuring changes in punished/unpunished responding. It is often used to screen drugs for their potential to inhibit anxiety (anxiolytic potential). Some researchers from France have conducted an experiment on "Effects of Chronic Antidepressants in an Operant Conflict Procedure of Anxiety in the rat (1998)", "the aim of their
