In Section 3, we analyze the case ofindirect government control, i.e., state subsidization of privately owned media. We endoge-nize government control in Section 4, asking when the government would choose to take overprivately owned media. Section 5 extends the model to multiple media outlets.
Small Angle Gradient Echo Methods. The gradient echo technique is generally used in combination with an RF excitation pulse that has a small flip angle of less than 90Ë. We will discover that the advantage of this is that it permits the use of shorter TR values and this, in turn, produces faster image acquisition.
An echocardiogram may utilize one or more of several special techniques: M-Mode echocardiography. This is the simplest type of echocardiography. It produces an image that is similar to a line tracing rather than an actual picture of heart structures.
