Adolf Hitler :: essays research papers

EARLY YEARS Adolf Hitler was born in Austria, on the 20th of April 1889. His father was a customs officer and his mother a peasant girl, he was a poor student who never completed high school. He lived in Vienna until 1913 and lived off his orphans pension and money from pictures he drew. He read a lot of books and began to develop anti-Jewish and antidemocratic beliefs, a like to outstanding individuals and a dislike for ordinary working people. In World War I Hitler, who was in Munich, volunteered in the *Bavarian army. He proved to be a dedicated and courageous soldier but he was never promoted beyond private first class. After Germany’s defeat in 1918 he returned to Munich staying in the army till 1920. His commander then made him an educational officer with the permission to justify his charges against pacifist and democratic ideas. In September 1919 he joined the nationalist German Workers party and in April 1920 he went on to work full time for the party that had changed its name to the National German Workers (nazi) party. In 1921 he was elected party chairman with very dominating powers. RISE TO POWER Hitler after organizing many meetings, terrorizing political rivals spread his racial hatred and soon became an important part in Bavarian Politics, and was assisted by his high officials and businessmen. In November 1923 he led an uprising against the Weimar Republic but without military support his rebellion failed and as the organizer he was sentenced to five years in prison, of which he served 8 months and was then released as the result of a general amnesty. He then rebuilt his party without interference from the government in December 1924. When the Great Depression struck in 1929 his theory of it as a Jewish plot to make Germany a communist country was accepted by many Germans, he then promised a stronger country with many jobs and national glory, he attracted millions of voters and Nazi representation in Germanys parliament rose from 12 seats to 107 in just 2 years. During the next two years the nazi party kept expanding and benefiting from the growing unemployment, fear of e veryone becoming an equal (communism) and the shyness of his political rivals. GERMANY’S DICTATOR When Hitler established himself as a dictator thousands of anti-Nazis were hauled off to concentration camps and all public knowledge was kept quiet. An Enabling Act passed by a passive legislature allowed him to modify the government system and judiciary, replace all labour unions with one Nazi controlled German Labour Front, and ban all political parties except his own.

Outline and Evaluate Research Essay

Many eyewitnesses are called to testify because they have witnessed a crime, accident or incident. The anxiety if this may cause an affect on the reliability of their EWT. There are two main issues in this question: firstly the prediction of the Yerkes Dodson Law that as arousal increases, then so does performance weather spotting, stage performance, or memory encoding, up to an individual optimum level. However, after this optimum level it is suggested that the performance of the individual will decline, this could be triggered by terror. This theory was supported by Deffenbacher et al’s research. The second issue is the â€Å"weapons focus effect†; In Easterbrook’s research he predicted that attention will narrow to the source of the threat e.g the knife the man is holding therefore peripheral detail is lost e.g the details of the perpertrator’s face. This was supported by Loftus’s laboratory studies in an artificial environment using film and sli des, using independent groups design, where a control conditions showed the participants a similar scene without weapons. In the first group they had a scene which they believed to be a real life violent crime involving a weapon, results showed that the participants remembered the knife in great detail but no other features, such as the perpetrator’s face clothing etc. However the participants in the control conditions witnessed the same person but only in a peaceful situation and the participants were able to recognise the man when given 50 photos. When we examine real life eye witness testimony recall however, there is excellent recall of detail, and the weapons-focus effect was not supported. Yullie and Cutshall (1986) conducted a natural experiment on 13 out of 21 bystanders who had witnessed a violent shooting 4-5 months previously. There recall was detailed and accurate and they were resistant to leading questions months after the event. Therefore, this suggest that bystanders had reached the optimum level ( Yerkes Dodson Law) when they they witnessed the death of the robber who had previously wounded the owner in Vancouver gun shop before the owner killed him. Weapon focus did not influence witness recall. Therefore we need to examine witnesses to the violent crime who faced a weapon rather than a bystander to confirm the effect of weapon focus shown by Loftus. The natural experiment conducted by Christanson and Hubinette (1993) in Sweden re-interviewed 58 witnesses (customers and bank tellers) to bank robberies that occurred around Stockholm in one year. Those witnesses who faced the weapon (bank  tellers) they had better recall and accuracy of the event after a period of time rather than the bystanders. Optimum arousal is suggested but weapon focus is challenged. The ecological validity of this evidence is high although the participants cannot be randomly assigned to the experiment and there is no control condition as there would be in a laboratory experiment. However, Laboratory experiments lack the intense arousal of a real crime so the supposed weapons effect may be the effect of distinct and unexpected events distracting participants to the unusual element in the familiar. A strong point of Loftus’s field experiment and supports the weapon focus effect; is that it has ecological validity and comparison to the control condition provide strong support. A criticism is the inability of researchers fro randomly allocate participants in this study to experimental and control conditions to control individual differences.

Formula for Ammonium Hydroxide

Ammonium hydroxide is the name given to any aqueous (water-based) solution of ammonia. In pure form, it is a clear liquid that smells strongly of ammonia. Household ammonia usually is 5-10% ammonium hydroxide solution. Other names for ammonium hydroxide are: Ammonia (e.g., household ammonia) [versus anhydrous ammonia]Aqueous ammoniaAmmonia solutionAmmonia waterAmmonia liquorAmmonical liquorSpirit of Hartshorn Chemical Formula of Ammonium Hydroxide The chemical formula of ammonium hydroxide is  NH4OH, but in practice, ammonia deprotonates some of the water, so the species found in solution are a combination of NH3,  NH4,, and OH− in water. Ammonium Hydroxide Uses Household ammonia, which is ammonium hydroxide, is a common cleaner. Its also used as a disinfectant, food leavening agent, to treat straw for cattle feed, to enhance tobacco flavor, to cycle an aquarium without fish, and as a chemical precursor for hexamethylenetetramine and ethylenediamine. In the chemistry lab, it is used for qualitative inorganic analysis and to dissolve silver oxide. Concentration of Saturated Solution Its important for chemists to realize the concentration of a saturated ammonium hydroxide solution decreases as temperature increases. If a saturated solution of ammonium hydroxide is prepared at a cool temperature and the sealed container is heated, the concentration of the solution decreases and ammonia gas can build up in the container, potentially leading it to rupture. At a minimum, unsealing the warm container releases toxic ammonia vapors. Safety Ammonia in any form is toxic, whether it is inhaled, absorbed through the skin, or ingested. Like most other bases, its also corrosive, which means it can burn skin or damage mucous membranes, such as eyes and the nasal cavity. Its also important to refrain from mixing ammonia with other household chemicals because they may react to release additional toxic fumes.
