This fact combined with ... of the forests in the Pacific Northwest have already been harvested. In order to protect the current owl population, the remaining forests would have to be preserved, but this would have a serious negative economical effect.

- 264: The Mind, Music, and Behavior
- ... many of the subjects reported that they felt pleasantly relaxed or comfortable… Music may evoke more organized mental activities which result in subjectively comfortable feelings." The white noise in the experiment produced an even greater effect; the volunteers were so relaxed that many felt drowsy and soporific. This sleepy effect can be explained by the monotonous characteristics of white noise, in contrast to the variations in tone and melody of normal music. Furthermore, the researchers found, based on the EEGs, that while listening to music ... no music played in the background. When the test subjects were asked to repeat the words a few days later, either the same music or a different background was present. The researcher noticed a "facilitative effect of providing the same [musical] context." Similar research has been done on CDM. CDM stands for context-dependent memory, which is the principle that "changing the context or environment in which material was originally ...
- 265: Andy Warhol And Pop Art
- ... automobile accidents. To most, it seemed as if the media were relating this as a warning. To Warhol, this was a "goal to be met." Also, Warhol was obsessed with the way vulgarity looses its effect after view multiple times. This is the reason that he multiplied car accident pictures many times. Many of his famous works, such as Car Crashes, Race Riots, Electric Chair, Suicides and Tuna Fish Disasters were ... screen method. In retrospect, the rubber stamp method he was using to repeat images over and over (a Warhol trademark) suddenly seemed to homemade-- he wanted something stronger that gave more of an assembly line effect. The silk-screening method was done by taking a photograph and transferring it in glue to silk, and then rolling ink across the silk so that the ink permeated only certain spots in the silk ... would produce a work without color first. Then, he would observe the work and think for days what the color should be used. Many times, color was applied by airbrush later to achieve an overlay effect. For the most part, his color schemes were bright. He also used a dot-matrix technique that spread color out by means of a tiny dot pattern. This was achieved through the silk-screening ...

Social Deconstruction Whichever determinant one believes to have the greater influence on intelligence, it is undeniable that the other still plays a part. Therefore, the environment in which we are raised has a direct effect on the type and the degree of intelligence we may develop, the only ambiguity is how large or small this effect might be. Even if only 30% of the variation in intelligence is attributable to environmental factors, this effect should still be detectable. Victoria J. Molfese, Lisabeth F. DiLalla, and Debra Bunce from Southern Illinois ...

The other elements that can have an effect on a wave are the tides, and also the surface of the ocean floor of which the wave is breaking over. To start with the tides effect the level of the water, and some ...

- ... opening of "Fiesta, 1980." Yunior’s narratives contain Spanish words an average of about every other sentence.

Yunior’s defense, but through language style rather than blatant statements. Yunior’s narration, besides being a political one, also appears very negative, but also extremely personal. His voice is conversational, which has a powerful effect: …trooped back into the living room with their plates a-heaping and all the adults ducked back into the living room, where the radio was playing loud-ass bachatas. (Drown, 37) In the above quote ... Diaz, having established a "close relationship" between reader and narrator, expects the reader to experience all of this simultaneously with Yunior. The reader suffers a let down in discovering Yunior’s unhappiness. Diaz creates the effect with language to contrast the reader’s disappointment with Yunior’s. Once again regarding Diaz’s language style, vulgarity and blatant phrases as well as cultural references add to the power of the story: ...
