– The Constant Gardener In the article “The Constant Gardener: What the Movie Missed” by Sonia Shah‚ she talks about the issues and concerns of new drugs being tested on people in developing countries such as Latin America‚ Eastern Europe‚ Asia and Africa. In Shah’s essay she brings up two convincing arguments against these experiments. One argument Shah speaks on is that in the movie The Constant Gardener the seriousness of the possible danger in these experiments is not well depicted. She argues

Remarks before starting the analysis of the dataset Purpose of the case We have to study three competitors (Dubuque‚ Ball Park‚ Oscar Mayer) in the market of the hot dog. We want to know the impact of the variation of the price of one competitor (Ball Park) on the market share of another competitor (Dubuque). Origin of the dataset The dataset comes from "a scanner study conducted at grocery stores located in the western suburbs of Chicago". So we know that the data don’t represent the entire

Report: Calculating the Spring Constant and Verifying that Energy is Conserved Within a System Abstract: An experiment was conducted to determine the spring constant of a spring in the cart by measuring the force required to compress a spring as well as the distance the spring compressed relative to the equilibrium position. A cart was placed onto a slanted track and speed and force censors were used to record appropriate data. The spring constant was determined by substituting

The coefficient measure the change in sigma given one unit change in year‚ holding all other factors constant. The third coefficient measure the interaction term between Dr and t. Thus‚ for countries before trade liberalization (D=0) the model become The coefficients and represent the intercept and the slope for

variables it is necessary to keep all the other possible variables constant throughout the experiment. 3.1 Length calculation In this experiment the same beam is used throughout and the centrally applied point load is kept constant. Thus keeping all possible variables other than the deflection y and the span L constant we may investigate the relationship between y and L. Let yLn where n is to be found Then y = k•Ln where k is a constant Taking logarithms: log y = n log L + log k which is in the

How to Work with Dummy Independent Variables Chapter 8 is devoted to dummy (independent) variables. This How To answers common questions on working with and interpreting dummy variables. Questions: 1) How to include dummy variables in a regression? 2) How to interpret a coefficient on a dummy variable? 3) How to test hypotheses with dummy variables and interaction terms? 4) How to create a double-log functional form with dummy variables? 5) How to interpret a coefficient on

hanging at the end. After the spring constant of 9.0312 N/m was measured‚ equations were used to determine a calculated frequency‚ that being 7.252 Hz. Four trials—each with a different sized‚ same massed object—took place where the object was pulled and allowed to rise and fall‚ while a sonic ranger motion sensor graphed the object’s position. The graphs created were transferred into Igor Pro‚ where a non-linear fit was created. From this fit‚ the damping constant of the object’s motion was given
