The essay will examine the role of the stress hormone cortisol, the level of which rises during REM sleep, and which impairs interactions between the neocortex and hippocampus. This is relevant because episodic memory is stored in the neocortex, while semantic memory is stored in the hippocampus. The essay will examine how the content of dreams in all stages fits in with the argument that the neoc ortex, which stores episodic memory, actively consolidates memory during non-REM sleep, while the hippocampus, which stores semantic memory, actively consolidates memory during REM sleep. For the most part, this large body of research provides a compelling argument for the proposition that sleep plays a role in memory consolidation and that dreaming is a by-product of this process. However, this view is not universally accepted. Therefore, this essay will also examine the criticisms of this theory, particularly in relation to the apparent lack of positive findings in some studies as well as issues with the methodology used by many of theShow MoreRelatedStephen P.

The Constitution fails to meet the needs of a rapidly changing society Free Essays

When the Constitution was written by the ‘Founding Fathers back in 1787, they intentionally made it so that it could survive over time. They made it flexable so because they envisaged that there were problems that they could not forsee in the future, these are things such as the Depression of the late twenties and early thirties. ‘The Framers’ intended for the amendment process to be the main way of updating the constitution and through time this has been evident. We will write a custom essay sample on The Constitution fails to meet the needs of a rapidly changing society or any similar topic only for you Order Now An important part of a democratic government is the accountability of those in power, in recent times we have seen the system in America fail, in part this may be due to the fact that the constitution may be outdated. During Bill Clintons’ second term of office there were a number of scandals that rocked the White House, the first being the Paula Jones affair. During a hearing about the Paula Jones affair Clinton stated that he had not had â€Å"sexual relations† with Monica Lewinsky, this turned out to be a lie and Congress attempted to impeach him. The impeachment failed due to the wording of the constitution as it was based on the fact that they believed he had committed ‘a high crime or misdemeanour’ but Clintons’ lawyers asked for a definition of this and Congress could not give one. This shows that the wording of the constitution was outdated or the constitution was badly worded. There was also a lack of accountability during the Watergate scandal as President Nixon was able to escape with no punishment even though he was part of a conspiracy to commit a felony, all charges against Nixon were dropped by his successor Gerald Ford due to the fact that Presidents have the power to withdraw charges against anybody in America. This shows that there is an essential part of the democratic process missing due to flaws in the constitution. When the constitution was first written in 1787 there was a strong possibility of war, so when the founding fathers drew up the constitution they added in an article which said that all people have the right to bear arms. This article has been problematic ever since. Within the last decade there have been many high profile shootings in schools such as Columbine, this has led to a stronger fight against the gun laws. There are those such as the National Rifle Association who say that that right can not be taken away from them as it is one of their constitution rights but there is a problem with that as within the preamble there is the mention of insuring domestic tranquillity, can this be done when there are children who can gain easy access to guns, there are also the problems with the number of deaths due to gun crimes, the right to life is also mentioned in the constitution. The flexibility of the constitution is crucial to its longevity as if it was too rigid it would not have lasted, there may be the problem though that it is too flexible. Over the years there hav been many changes in the federal system, most notably the introduction of Roosevelts ‘New Deal’ which saw the power shift more towards the central government, then there was the move back through presidents such as Nixon and Reagan. During this time the efficacy of the government could be questioned as we saw with the ‘Appropreations Crisis’ in 1995, during this time government was shut down for two weeks this was ineffect shutting down the country as federal run services such as the postal service were also closed. A solution was found to stop that happening again, that arrived in the form of the ‘Line Item Veto’, this gave the President the power to remove unsuitable sentences or paragraphs from a bill. Eighteen months after its introduction it was scrapped as the Supreme Court ruled it unconstitutional as it gave too much power to one person. Many considered this as a mistake as it made the legislative process faster as it saved the bill being sent back to Congress. This shows that there is room for improvement within the constitution. Through time the main way to update the constitution has been through the Amendment process. As society and its ideals has changed so has the Constitution, when society started to object to slavery and racism the constitution began to follow, the same with womens rights. There are other problems as I have already mentioned the constitution still protects the pro-gun lobby as it is stated in the constitution that all citizens shall bear arms, after a number of atrocities and the significant rise in gun crime, society is begininng to object but still there is no movement on any new amendments in regards to gun laws. The lack of movement may be due to the constitution being outdated but it may also be due to the power that the NRA and other pro gun groups have but we have seen great trides taken through time such as the moves against racism. The constitution was based on what was happening in the eighteenth century and what the ‘Framers’ envisaged would happen in the future, but there would seem to be the ability within it, due to its flexibility, to change with modern society. Through time we have seen how society has changed and not far behind is the constitution due to the amendment process.

Promotional car brochure stand for a car company Essay Example For Students

Promotional car brochure stand for a car company Essay I have to design a temporary promotional car brochure stand for a car company. There are many important features that need to be included in the design. Â  Needs to attract the attention of potential customers because otherwise they might go to a rival and purchase off them. I will do this by using vibrant colours that stand out like black yellow, or black sliver; this can make the stand look expensive. The stand will also have to with stand testing of dropping brochures into the stand and any other ware an tare that might occur. This is because people may put back brochures and they dont care if they drop them in so it has to with stand the tests. The brochure stand that I will produce will be sturdy and not cheap, otherwise it wont attract customers. The brochure stand is an important feature to the car market as it can help sell the brochures so that there are more potential customers. Therefore the design must be aesthetically pleasing. Â  I will use the information I get from my questionnaires to develop my ideas to create the best idea for my final design. Must be made of suitable material because there would be no point making it out of Titanium when it would look as good and cost less with aluminium that can also be recycled. Should be a seasonable size because if its too tall people wouldnt be able to reach it and too small and there is a danger of it getting stolen or crushed. Blend in well with the environment because it would not look nice if you had e. g. a land rover stall with wood and mud and then the brochure stand was shinny metal it would look wrong. Â  Must be able to stand upright on a flat surface so that it does not fall over.
