An Occurrence at Owl Creek Bridge by Ambrose Bierce Essay

An Occurrence at Owl Creek Bridge by Ambrose Bierce - Essay Example As the time ticks, Farquhar wafts into a dream-like state where there is no limitation of time. The author compares his situation to that of a ‘vast pendulum’ which swings uncontrollably. The space in which Farquhar delves is an intermediary between life and death, a world that is bound by its unknown rules. There is a very thin boundary between illusion and reality and till the end of the story readers think of Farquhar’s illusion as reality. He is desperate to see his wife and children again and in his desperation his mind creates a different world that can provide him an escape from this predicament. The story makes it clear that to a certain degree, the nature of time is subjective. During the brief time interval between Farquhar’s fall and death, the time dilates and slows down to allow for the events to take place as the mind wishes. He evades bullets, cannons, soldiers and makes a tiring journey to see his family. But just when he is about to embrace his wife, a white flash of light brings him back to reality and his neck breaks (Bierce, 2010).

Answer the Questions - Assignment Example Random error occurs within the experiment itself. Bias is systematic errors in an epidemiologic study that brings an incorrect estimate of the connection between exposures and outcomes. Bias can be divided into categories that is the selection, and information bias. Selection bias occurs when selection into a study gives results that are different from what is expected if the entire population was involved (McDaniel and Roger, Pp 15). If an individual involves the whole population and collects accurate data, then an individual could compute the correct association. If sampling is not represented by outcome distribution of the whole population, the measures of connection will be biased. A typical example is a jar filled with marbles of 500 red and 500 blue that are mixed randomly. If a person pulls out 50 at random, he is likely to get 25 red and 25 blue. It is also possible to get 27 red and 23 or 29 blue and 21 red. An individual can also get 40 red or 10 blue, which is highly unlikely because each is likely to be proportioned (McDaniel and Roger, Pp 35). This is a form of random error. Systematic error might occur when the blue marbles are near the top, and the reds are at the bottom. When an individual pulls from the top, he is likely to get 37 blues and 13 red because an individual is not getting a sample that represent the whole jar. Behaviour targeting is the act of targeting users based on their behaviour of using the internet. This behaviour is used to target online ads, but the techniques can also be used to target products. Behavioural targeting is used to target the people that matter most. Behaviour targeting only needs to give the audience the right information and the message they need. It divides users according to the content they watch on the sites (McDaniel and Roger, Pp 56). They are also targeted with a message that is appropriate to that segment. Behaviour targeting is deployed in two ways, which are on-site and network targeting.
