The following article was published by Reuters and contains a serious methodological flaw. "WASHINGTON (Reuters) -- Brain scans show that the brains of people who are lying look very different from those of people who are telling the truth‚ U.S. researchers said on Monday. The study‚ using functional magnetic resonance imaging or fMRI‚ not only sheds light on what goes on when people lie but may also provide new technology for lie-detecting‚ the researchers said. "There may be unique areas

an exposure to fertilizer. By changing the independent variable (whether or not the plant was planted with fertilizer)‚ you are testing to see how the dependent variable would change (the growth of plants). In order to assure that there is no experimental error‚ a control must be kept to produce the most accurate data on what effect fertilizer has on plant growth. Although many environmental factors could be tested‚ such as the amount of sunlight exposed to or the amount of water given‚ some of the

Prevent Medical Errors One in seven Medicare patients in hospitals experience a medical error. But medical errors can occur anywhere in the health care system: In hospitals‚ clinics‚ surgery centers‚ doctors’ offices‚ nursing homes‚ pharmacies‚ and patients’ homes. Errors can involve medicines‚ surgery‚ diagnosis‚ equipment‚ or lab reports. They can happen during even the most routine tasks‚ such as when a hospital patient on a salt-free diet is given a high-salt meal. Most errors result from

Controls: Respirometer with only beads in it because it does not undergo any respiration Approach Two sets of three respirometers will be assembled during this lab exercise. Each set will be incubated at a different temperature. One respirometer will contain germinated seeds‚ one will contain a mix of non-germinating seeds and glass beads‚ and a third will contain

Lab #5: Refraction of Light Theory: Refraction can be defined as the bending of a wave when it enters a medium which causes it to have some reduced speed. In terms of light‚ refraction occurs when the ray passes through some medium which slows its speed; such as water or glass. In this instance the ray tends to bend towards the normal of the medium. The amount of bending or refraction which occurs can be calculated using Snell’s Law (). Objective: To measure the index of refraction of Lucite

5.5 Experimental Setup We here briefly describe the classification algorithms applied‚ the BBC forum dataset [112] used and the performance evaluation measures used to analyze the results. 5.5.1 Classification Algorithms For classification task‚ in this module‚ we used the four classification algorithms of Support Vector Machine‚ Decision Tree‚ Naïve Bayes and Logistic Regression provided in ODM[107]. As discussed earlier that it is used for data mining tasks in a number of existing research works[108-110]

methods are experimental and correlational. Many researchers use both methods to find outcome of their research. They may explore different avenues of an approach to gain the results they want. We will be describing the two methods and finding out which one is best. The definition of the experimental method is a scientific method message to confirm cause-and-effect relationships by introducing independent variables and observing their effects on dependent. “An example of experimental method‚ suppose

Medical Errors Medical errors are avoidable negative effects of care‚ which can be harmful to a patient. These errors can vary from giving the wrong treatment to a disease‚ injury‚ syndrome‚ behavior‚ or infection a patient might have. Nurses play one of the most important roles in the avoidance of occurring medical errors. By doing their job correctly they can prevent the errors from happening and potentially hurting or killing a patient. Decimal errors‚ trailing zero errors and abbreviation errors
