The models we discussed are models that are linear in parameters; variables Y and Xs do not necessarily have to be linear The price elasticity of demand~the log-linear models The rate of growth~semilog model Functional forms of regression models which are linear in parameters, but not necessarily linear in variables:

The surplus amino acids in animals can be completely oxidized or converted to other storable fuels Amino acids in excess (from diet, protein turnover) can neither be stored, nor excreted, but oxidized to release energy or converted to fatty acids or glucose. Animals also utilize amino acid for energy generation during starvation or in diabetes mellitus

Motivation DESCRIBE the three distinct components of motivation. IDENTIFY the need levels in Maslow's hierarchy. EXPLAIN Alderfer's ERG Theory. COMPARE motivators and hygiene factors DISCUSS the factors that reflect a high need for achievement. DEFINE the key terms in expectancy theory. DISTINGUISH between inputs and outputs in equity theory

In lecture D9, we saw the principle of impulse and momentum applied to particle motion. This principle was of particular importance when the applied forces were functions of time and when interactions between particles occurred over very short times, such as with impact forces. In this lecture, we extend these principles to two dimensional rigid body dynamics. Impulse and Momentum Equations Linear Momentum In lecture D18, we introduced the equations of motion for a two dimensional rigid body. The linear momen- tum for a system of particles is defined

In this lecture, we will revisit the principle of work and energy introduced in lecture D7 for particle dynamics, and extend it to 2D rigid body dynamics. Kinetic Energy for a 2D Rigid Body We start by recalling the kinetic energy expression for a system of particles derived in lecture D17

In this paper we discuss the role of the media in pressuring corporate managers and directors to behave in ways that are \socially acceptable. Sometimes this coincides with shareholders' value maximization others not. We provide both anecdotal and systematic evidence that media affect companies' policy toward the environment and the amount of corporate resources that are diverted to the sole advantage of controlling shareholders. Our results have important consequences for the focus of the corporate governance debate and for the feasibility of reforms aimed at improving corporate governance around the

An accelerometer is a device used to measure linear acceleration without an external reference. The main idea has already been illustrated in the previous lecture with the example of the boy in the elevator. Clearly, if we know the weight of the boy when the acceleration is zero, we can determine from the reading on the scale the value of the acceleration. In summary, the acceleration will produce an inertial force on a test mass, and this force can be nulled and measured with precision. Below we have sketch of a very simple one axis accelerometer

Numerous empirical studies have demonstrated that asset prices react rapidly, if at all, to news published in the mass media. In many cases, the information has been discounted and prices have already moved upon primary publication through news wires, press releases or firm announcements. Any remaining information is usually quickly priced in after

Interest groups seek to influence economic activity through public and private politics. Public politics takes place in the arenas of public inst it utions, whereas private politics takes place out side public inst itutions oft en in the arena of public sentiment. Private politics refers to action by interest groups directed at private parties, as in the case of an activist group launching a campaign against a firm
