Psychology - Learning essays

Psychology - Learning essays There are many different kinds of ways that people and animals learn. People can adjust the way they learn to the different situations in which they are learning and what they have to learn. One form of learning is known as conditioning. Conditioning emphasises the relationship between stimuli and responses. The two types of conditioning found are Classical conditioning and Operant conditioning. Learning may occur in different ways. Psychologists have distinguished between different types of learning, these being Observational Learning and Insight Learning. Classical conditioning refers to a simple form of learning, which occurs through the repeated association of two or more different stimuli. Learning is only said to have occurred once a particular stimulus always produces a response which it did not previously produce. Classical conditioning involves an unconditioned stimulus and an unconditioned response, aswell as a conditioned stimulus and a conditioned response. The unconditioned stimulus is any stimulus, which consistently produces a naturally occurring, automatic response. The unconditioned response is a reflexive and involuntary response, which occurs as a result of the unconditioned stimulus. The conditioned stimulus is the stimulus that is neutral at the beginning of the conditioning process and does not produce the unconditioned response. But through repeated association with the conditioned stimulus, triggers the same response as the unconditioned stimulus. The conditioned response is the learned response that is b rought forth by the conditioned stimulus. The conditioned response occurs after the conditioned stimulus has been associated with the unconditioned stimulus. An example of classical conditioning is when a person walks past a certain house each day and every time is attacked by a large dog. They then associate that house with the dog and avoid walking past there again. In this example the ...

Mahdist War and the Siege of Khartoum

Mahdist War and the Siege of Khartoum Siege of Khartoum - Conflict Dates: The Siege of Khartoum lasted from March 13, 1884 to January 26, 1885, and took place during the Mahdist War (1881-1899). Armies Commanders British Egyptians Major General Charles Gordon7,000 men, 9 gunboats Mahdists Muhammad Ahmadapprox. 50,000 men Siege of Khartoum - Background: In the wake of 1882 Anglo-Egyptian War, British troops remained in Egypt to protect British interests. Though occupying the country, they allowed the Khedive to continue overseeing domestic affairs. This included dealing with the Mahdist Revolt which had commenced in Sudan. Though technically under Egyptian rule, large parts of Sudan had fallen to Mahdist forces led by Muhammad Ahmad. Considering himself the Mahdi (the redeemer of Islam), Ahmad defeated Egyptian forces at El Obeid in November 1883 and overran Kordofan and Darfur. This defeat and the deteriorating situation led to Sudan being discussed in Parliament. Assessing the problem and wishing to avoid the cost of intervention, Prime Minister William Gladstone and his cabinet were unwilling to commit forces to the conflict. As a result, their representative in Cairo, Sir Evelyn Baring, directed the Khedive to order the garrisons in Sudan to evacuate back into Egypt. To oversee this operation, London requested that Major General Charles Chinese Gordon be placed in command. A veteran officer and former governor-general of Sudan, Gordon was familiar with the region and its peoples. Leaving in early 1884, he was also tasked with reporting on the best means for extracting the Egyptians from the conflict. Arriving in Cairo, he was re-appointed Governor-General of Sudan with full executive powers. Sailing up the Nile, he arrived at Khartoum on February 18. Directing his limited forces against the advancing Mahdists, Gordon began evacuating women and children north to Egypt. Siege of Khartoum - Gordon Digs In: Though London desired to abandon Sudan, Gordon firmly believed the Mahdists needed to be defeated or they could overrun Egypt. Citing a lack of boats and transport, he ignored his orders to evacuate and began organizing a defense of Khartoum. In an effort to win over the citys residents, he improved the justice system and remitted taxes. Recognizing that Khartoums economy rested on the slave trade, he re-legalized slavery despite the fact that he had originally abolished it during his earlier term as governor-general. While unpopular at home, this move increased Gordons support in the city. As he moved forward, he began requesting reinforcements to defend the city. An initial request for a regiment of Turkish troops was denied as was a later call for a force of Indian Muslims. Increasingly agitated by Gladstones lack of support, Gordon began sending a series of angry telegrams to London. These soon became public and led to a vote of no confidence against Gladstones government. Though he survived, Gladstone steadfastly refused to become committed to a war in Sudan. Left on his own, Gordon began enhancing Khartoums defenses. Protected to the north and west by the White and Blue Niles, he saw that fortifications and trenches were constructed to the south and east. Facing the desert, these were supported by land mines and wire barriers. To defend the rivers, Gordon retrofitted several steamers into gunboats which were protected by metal plates. Attempting an offensive near Halfaya on March 16, Gordons troops faltered and took 200 casualties. In the wake of the setback, he concluded that he should remain on the defensive. Siege of Khartoum - The Siege Begins: Later that month, Mahdist forces began to near Khartoum and skirmishing commenced. With Mahdist forces closing in, Gordon telegraphed London on April 19 that he had provisions for five months. He also requested two to three thousand Turkish troops as his men were increasingly unreliable. Gordon believed that with such a force, he could drive off the enemy. As the month ended, the tribes to the north elected to join with the Mahdi and cut off Gordons lines of communication to Egypt. While runners were able to make the journey, the Nile and telegraph were severed. As enemy forces surrounded the city, Gordon attempted to convince the Mahdi to make peace but with no success. Siege of Khartoum - Fall of Khartoum: Holding the city, Gordon was able to somewhat replenish his supplies by raiding with his gunboats. In London, his plight was played up in the press and eventually, Queen Victoria directed Gladstone to send aid to the beleaguered garrison. Acquiescing in July 1884, Gladstone ordered General Sir Garnet Wolseley to form an expedition for the relief of Khartoum. Despite this, it took a substantial amount of time to organize the needed men and supplies. As the fall progressed, Gordons position became increasingly tenuous as supplies dwindled and many of his more capable officers were killed. Shortening his line, he constructed a new wall inside the city and tower from which to observe the enemy. Though communications remained spotty, Gordon did receive word that a relief expedition was en route. Despite this news, Gordon greatly feared for the city. A letter that arrived in Cairo on December 14 informed a friend, Farewell. You will never hear from me again. I fear that there will be treachery in the garrison, and all will be over by Christmas. Two days later, Gordon was forced to destroy his outpost across the White Nile at Omdurman. Made aware of Gordons concerns, Wolseley began pressing south. Defeating the Mahdists at Abu Klea on January 17, 1885, the men met the enemy again two days later. With the relief force approaching, the Mahdi began planning to storm Khartoum. Possessing around 50,000 men, he ordered one column to wade across the White Nile to attack the citys walls while another assaulted the Massalamieh Gate. Moving forward on the night of January 25-26, both columns quickly overwhelmed the exhausted defenders. Swarming through the city, the Mahdists massacred the garrison and around 4,000 of Khartoums residents. Though the Mahdi had expressly ordered that Gordon be taken alive, he was struck down in the fighting. Accounts of his death vary with some reports stating he was killed at the governors palace, while others claim he was shot in the street while trying to escape to the Austrian consulate. In either case, Gordons body was decapitated and taken to the Mahdi on a pike. Siege of Khartoum - Aftermath: In the fighting at Khartoum, Gordons entire 7,000-man garrison was killed. Mahdist casualties are not known. Driving south, Wolseleys relief force reached Khartoum two days after the citys fall. With no reason to remain, he ordered his men to return to Egypt, leaving Sudan to the Mahdi. It remained under Mahdist control until 1898 when Major General Herbert Kitchener defeated them at the Battle of Omdurman. Though a search was made for Gordons remains after Khartoum was retaken, they were never found. Acclaimed by the public, Gordons death was blamed on Gladstone who delayed forming a relief expedition. The resulting outcry led his government to fall in March 1885 and he was formally rebuked by Queen Victoria. Sources: BBC. General Charles Gordon.

Main Responsibilities in the Nursing Profession Essay

Main Responsibilities in the Nursing Profession - Essay Example In 2008, the National Survey of Registered Nurses conducted research and found out that over 3 million nurses were registered. There are only 2.6 million nurses who have been employed out of the 3 million registered nurses. Out of these 2.6 million which is an equivalent of 84%, 50.0% are nurses prepared from Baccalaureate programs, 36.1% from Associate Degree programs while 13.9% were from Diploma Nursing Programs. The NCLEX-RN licensing examination is taken by those who are to be recognized as certified nurses. Robert Wood Johnson Foundation made a proposal in a report. This report on The Future of Nursing suggested that 50.0% of BSN should be increased to 80%. Many types of research have also been conducted, and the findings reported that BSN in most care centres has realized a reduced rate of mortality deaths. American Organization of Nurse Executives called for all nurses to undergo the Baccalaureate programs. This program is to make them competent enough to handle the challengi ng task ahead of their careers. The U.S Army requires nurses that are competent specifically with a degree in baccalaureate nursing so that these nurses can be given the position of a commissioned nurse. A study was conducted showing that a large number of people preferred nurses who were trained for the duration of four years and over. It is only fair that the life of a patient is entrusted on a competent nurse. This paper will explore the difference in competencies that are notable between associate-degree nurses and nurses who have been prepared at the Baccalaureate-degree level in nursing. Baccalaureate nursing program is inclusive of all the course work that is taught in diploma and associate degree level. The four-year training they go through is seen in the care they extend to patients. Baccalaureate nurses are taught on theoretical and practical aspects. These theories incorporate the various fields outside medicine. Nursing knowledge includes theories in humanities, science s, as well as, Biblical concepts.

Ancient Art: How It Affects Society Today Essay

Ancient art has a timeless value on how it affects society today. In order to interoperate each work of art, an individual must have a full knowledgeable concept of how to define each piece. This essay defines each the Mona Lisa created by Leonardo Da Vinci and the Venus de Milo sculpted by Alexandros of Antioch. It defines the form, subject matter, and content for both pieces. The comparison between both pieces is very much different in concepts, but the meaning of both, hold so much of value is very similar by level of representation. Ancient Art Art within itself defines who we are as individuals through the way we express our; feelings, emotions, expressions, and things we create. Looking at the â€Å"Mona Lisa† created by Leonardo Da Vinci, this was certainly a masterpiece that captured the eyes of many through its meaning and design. In a resemblance to art, the â€Å"Venus de Milo† created by Alexandros of Antioch, was a spectacular sculpture that was dated back to 100BC and speaks too many about its characteristic. There are many different aspects to define each artwork such as; the form, subject matter, and its content. Relating art to its time is a crucial aspect to know and understand what possessed meaning during that time. The form of the work is a very crucial aspect to apply when looking at art work. The Mona Lisa is a two-dimensional oil painting on a panel of wood. The painting technique Leonardo da Vinci used was called sfumato (the Italian word for smoke) which involves using several translucent layers of color to produce depth in the painting. I t is still unknown how Leonardo applied the paint as there is no obvious evidence of brush strokes or use of fingers. As for the Venus de Milo, it was a three-dimensional sculpture created out of Italian marble which is a hard stone that has a fine grain which allows for it to be carved with a high degree of detail. According to Lee (2013), â€Å"The Venus de Milo was carved from at least six to seven blocks of Parian marble: one block for the nude torso, another block for the draped legs, another block apiece for each arm, another small block for the left foot, another block for the inscribed plinth and finally the separately carved herm that stood beside the goddess.† Obviously the two differ in many different perspectives. First, sculpting and painting are two different forms of art but the intensive meaning behind both of them represent how much impact art has on society. The material and techniques varied in many different aspects as well and the color, whereas marble wasn’t available in different color schemes. The subject matter behind each piece was a representational outlook for highly respected and loved individuals. From what an individual can gather immediately looking at the Mona Lisa is that, from the sad expression on her face shows meaning behind her life. As for the Venus de Milo, individuals could gather it was someone of value in that era of time. Each with a powerful meaning behind each, but for those who know very little about art could not literally depict what it was actually representing. The content to these two masterpieces are very significant in meaning. The Mona Lisa Possessed a very interesting meaning behind the painting. The name of which the Mona Lisa was given was from Lisa del Giocondo, the wife of a wealthy Florence businessman. In modern Italian, â€Å"mona† means â€Å"my lady† or â€Å"madam,† so the title means â€Å"Madam Lisa†. According to Gwen Bruno (2009), â€Å"the portrait really represents the former Duchess of Milan, Isabella of Aragon and that her sad expression is due to her unhappy marriage.† The sculpture of Venus de Milo is the representation of the Greek goddess of love and beauty, is meant to be the depiction of pure beauty and perfection, (Mike De Rose, 2008). The action and modernized drapery give the Venus great nobility of a goddess. According to Mike De Rose (2008), â€Å"the Venus de Milo represents the girl that this man can never have, and acts as a fantasy for him. When Dario writes â€Å"in the impossible embrace of the Venus de Milo†, he is portraying how it would be impossible to hold or even touch this girl.† The time periods from which these were created were of substantial value to those of its time. The Mona Lisa more accurately fits the description of so by customs and values during that time. The Venus de Milo was more theory opposed to a literal value because she was of creation. Both of the timeless pieces of art will forever hold their value and meaning and will always be cherished. References * Gwen Bruno. (2009). â€Å"What Does the Mona Lisa Represent?† Demand Media Inc.

Cognitive Behavioral Therapy For Insomnia - 2852 Words

Cognitive Behavioral Therapy for Insomnia Bobbi Marie Pollard Loyola University Chicago School of Social Work Abstract Cognitive behavioral therapy for insomnia is a recent framework developed to address the dysfunctional cognitions and behaviors that contribute to poor sleeping patterns. Insomnia often presents as a comorbidity to a medical or psychiatric disorder, but may also be an isolated diagnosis. According to research studies, benzodiazepine-receptor agonists (BzRAs) and cognitive behavioral therapy (CBT) are the two most effective therapies for treatment and management of insomnia. And while both treatments are beneficial for short-term management of insomnia, CBTi produces long-term sustained benefits with no side effects thus being more advantageous that prescription drug use only. CBTi involves five components: stimulus control, sleep restriction, relaxation training, cognitive therapy and sleep hygiene education. Because CBTi is a fairly new approach, trained professionals may be difficult to find; creative delivery of therapy through telephone or Skype appointments may be necessary. Ke ywords: insomnia, sleep, cognitive, behavioral, CBTi, sleep therapy Insomnia Insomnia is the most common sleep disorder.
