Animal behavior :: essays research papers

The study of animal behavior is Ethology. A large part of the studies have been conducted by Lonrenz and Niko Tinbergen who wanted to find out how animals saw the world.   Ã‚  Ã‚  Ã‚  Ã‚  For example, fishes. The male will protect its territory. They will become aggressive when they see the red belly of another fish. This reaction is innate or instinctive, it is automatic. An experiment was performed by placing a large red sheet of paper in the tank. This made the male fish aggressive. This aggressiveness is what will make the male more â€Å"fit† in order provide more sperm to the females. The red was the releaser/sign stimuli in this case.   Ã‚  Ã‚  Ã‚  Ã‚  If you take a chick for example, its mother will respond to sound instead of sight. When a chick is distressed and is placed in a sound proof container, the mother will not respond. However, when there is a physical barrier but not sound proof, the mother will respond to the chick’s cries. The releaser/sign stimulus is sound in this case. A bee will never see a white flower but instead it will see the â€Å"target’, which is the pollen.   Ã‚  Ã‚  Ã‚  Ã‚  Pheromones are not hormones. They are chemicals that are released outside of the animal, and have a scent that will give an effect. Therefore, pheromones can also be releaser/sign stimuli as well.   Ã‚  Ã‚  Ã‚  Ã‚  When a gull has captured a plentiful supply of fish in its neck, the baby will peck at its mother so the fish will be released for them to feed on. The baby gulls will respond to the back and forth swinging and the red dot on the mother’s beak.   Ã‚  Ã‚  Ã‚  Ã‚  When a releaser leads directly to behavior it is called a fix-action pattern. If an egg rolls out of a nest the mother will immediately try and recollect it. But if the egg is taken away the mother will still do it. This shows that once the switch is turned on it will continue. Fix action patterns can be learned by humans, and will soon become autonomic.   Ã‚  Ã‚  Ã‚  Ã‚  Usually hormones and timing will motivate animals and drive their behavior; timing through biological clocks, the animals circadium rhythms (approx 24hrs). This circadium rhythm may be altered by changing the animal’s environment. If a squirrel is put into the dark and exposed to artificial light, its cycle may shift. Each cell has a biological clock, which means each organ as well as the individual animal has one.

Nursing During Civil War Essay

The American Civil War occurred between 1861 and 1865. When the war began, there was no organized medical corps for either the Union Army or the Confederate Army. Up until then, nursing was still considered a â€Å"loose term† as far what a nurse is and does. There were no official nursing schools or professional trained nurses available. As newspapers wrote about the poor and unsanitary conditions that wounded solider were subjected to, hundreds of women volunteered to help provide assistance to the wound solders (Egenes). Make-shift hospital and clinics were created on the battlefield to care for the wounded. As a result of having no organized medical corps in the army, conditions at most of the hospitals were poor. More soldiers during this time died of complications other than battlefield wounds such as dysentery, small pox, and pneumonia. (Son of the South). Hospitals were overcrowded and nurses lacked adequate quality of food and water, clean clothing, sanitation equipment, and other medication supplies to properly provide care for the injured. Because of this, hospitals were breeding grounds for disease and death. During this time, army physicians did not favor female volunteer nurses, believing female nurses were inexperienced and disorganized. Several woman help elevate the status of nurses during the Civil War and on. One woman that did just that was Dorothea Dix. Dix was a school teacher that was appointed as the Superintendent of Army Nursing for the Union Army. Through her position she was able to help organized medical efforts, set standards for military nurses, and to lobby for medical supplies for the Union Army. Another woman that had an impact on nursing was Clara Burton, also known as â€Å"Angel of the Battlefield. After her father died, she began to collect supplies and provide care to the wounded at the front lines. As word around the army grew about her compassion and care, Burton began getting support for her cause and the nursing cause as a whole. After the war, she continued her efforts in nursing and eventually inaugurated a movement to gain recognition for the International Committee of the Red Cross by the United States government (Epler).

How do Hardy and Wordsworth explore The theme of Nature and Childhood? Essay

Nature is beautiful. This is views of people in the 18th century. Nature was loved and appreciated back in time, true life based poems were written about it, two of them were Thomas hardy & William Wordsworth. These two poets were in love with nature not only did they write about it they fell in deep love with nature that they expressed their feelings within their poetry to the world. There is a quote in Hardy’s poem â€Å"I could live on thus till end†, point is that he could live with/sacrifice all his life for nature, just like a man sacrifices his life to women when he takes a marriage vow quote is â€Å"until death do us part† this shows the personification from nature to a human being Whereas Wordsworth has a different way of expressing his feelings which is describing nature with obsession such as â€Å"Small circles glittering idly in the moon,† Hardy’s poem ‘Childhood among ferns’ shows six different sides to nature which are: Beauty (â€Å"ferns spread out luxuriantly†), power (â€Å"The rain gained strength†); it acts like a: parent (â€Å"tall ferns sheltered me†) and friend (â€Å"brought forth a sweet breath†), and also he is at one with nature. William and hardy use a wide range of punctuation and description for effect and also for description of their wonderful nature. This is a very strong quote showing the beautiful side of nature â€Å"The sun then burst, and brought forth a sweet breath†¦Ã¢â‚¬  this quote is a personification of a human breathing and usually its friends that are sweet to you so it is also showing 2 faces to nature the other side is power â€Å"burst† this is a very strong word to use to explain the power of nature which gives a dramatic effect clearly shown to the reader as in Wordsworth poem he also shows the power of nature in his words â€Å"with voluntary power instinct† as if using a lot of its own power is sounds like a lot of power is being used by nature on its own. Childhood is also exposed by both poets but in individual ways such a Hardy wishes to go back to his childhood whereas William just has memories on his childhood â€Å"A schoolboy traveller at the holidays† and Hardy’s quote showing the point is â€Å"making pretence I was not rained upon†. This is showing Hardy’s childish acts for example when a child is having fun in the rain he does not want to go in the house just the same Thomas is pretending that there is no rain because he is refusing to take cover. In the prelude the childish act that the schoolboy does is he finds a boat on his way and immediately starts to own the boat and call it his possession. â€Å"A skiff that to a willow tree was tied within a rocky cave, its usual home†¦discovered thus by unexpected chance,† and soon after â€Å"my little boat mov’d on†. The personification used in ‘The Prelude’ is the boat which he says â€Å"surely I was led by her†, the her is the boat and it also shows the relationship of nature, well usually at one glance her could be a mother which usually would be first thoughts, because a boy is usually only led one women; his mother. After Thomas Hardy expresses his feelings at the end he also wants to stay in his childhood and live with nature for the rest of his living life â€Å"Why should I have to grow to man’s estate, And this afar-noises World perambulate?†. This quote shapes the writer telling us that he still hasn’t left his childhood he wants old memories back and he still has as much love for nature as he did as a child. Thomas also ha a view that he is at one with nature, the last side of nature where quoted â€Å"I sat on† which also compare William Wordsworth where he is also at one with nature when â€Å"went heaving through the water like a swan†. William calls himself a swan, the way he pushed his boat with difficulty through the water on his journey.
