decreases or when target width increases movement time is shorter (Fitts‚ 1954). Fitts found that the relationship between amplitude and width was given by the equation: MT= a + b[log2(2A/W)]. The empirical constants a and b represent the y-intercept and the slope (Schmidt & Lee‚ 2011). The purpose of this laboratory was to investigate the linear relationship between the index of difficulty and movement time. Furthermore‚ the target width-amplitude relationship was observed. The goal was to determine

A Case Study on Cost Estimation and Profitability Analysis at Continental Airlines Francisco J. Román Introduction In 2008‚ the senior management team at Continental Airlines‚ commanded by Lawrence Kellner‚ the Chairman and Chief Executive Officer‚ convened a special meeting to discuss the firm’s latest quarterly financial results. A bleak situation lay before them. Continental had incurred an operating loss of $71 million dollars—its second consecutive quarterly earnings decline that year

Observation on U.S. Treasury Yields Date: Oct 10‚ 2012 Introduction In this paper‚ we establish three regression models on U.S. Treasury yields with two different maturities: three-month and one-year. Model 1 is to interpret the relationship between unemployment rates and the risk-free rates‚ which we choose the three-month T-bill interest rates. Model 2 is to evaluate the movement of short-term interest rates under pure expectation theory and liquidity premium theory as well as to compare

Specify the components of a regression model that can be used to estimate a demand equation. 4. Interpret the regression results (i.e.‚ explain the quantitative impact that changes in the determinants have on the quantity demanded). 5. Explain the meaning of R2. 6. Evaluate the statistical significance of the regression coefficients using the t-test

Objective The objective of this experiment was to find the focal length of two converging lenses separately and also to find the focal length of combination of two converging lenses. Another objective was to study the image formed by a converging lens plus diverging lens. Background This experiment focused on a simple lens system. A simple lens is a piece of glassware that is spherical on one side and flat on another side‚ or spherical on both sides. There are two different types of lenses

First‚ it is assumed that individuals can rank their preferences for alternative bundles of goods and services. Consider a world in which only two goods X and Y are available. Suppose that a consumer is confronted with the following combinations of those two goods: Bundle C 4 units of X 4 units of Y The ability
