Article Review on Technology in Education Assignment

Article Review on Technology in Education - Assignment Example Videoconferencing at present is a medium for learning partnerships both in the local scene and in the international setup. Reynard (2012) cited â€Å"the inclusion of video increases the sense of presence,† and considers this as a means of collaboration. This educational tool has evolved in the recent years to include media tools, such as chat, as well as interactive whiteboards, which increase the exchange of ideas and resources alike, taking learning and the accumulation of knowledge to new heights (Reynard, 2012). This promotes access to what is otherwise accessible – locations which are commonly not that open to the public and expert educators who are too geographically distant; in reference to inaccessible locations, virtual tours are utilized (Reynard, 2012). Another advantage of this modern day educational tool is that it can make available the unavailable, such as classes not normally offered in the school, or those beyond the normal hours of school, which would be highly advantageous for those who are not able to avail of normal class hours (Reynard, 2012). Another important benefit of videoconferencing is that it helps students go the extra mile – tutoring and enrichment activities online, in real time, and without geographical constraints (Reynard, 2012). ... Furthermore, technology like videoconferencing may bridge the gap between different cultures as it provides worldwide reach to all students; this would yield better-informed students and well versed in aspects in which traditional students are not due to limited access to resources. There would be constant updates of any advancement or modification in education across the globe, as this education tool goes beyond geographical boundaries. In the future, students would be more interested and involved to learn as videoconferencing offers them interactive learning. It would give new meaning to the term – experience – since this teaching strategy would make the learners feel as if they are in that particular scenario, hence, making them believe like it was their own personal experience. There would probably be an increase in the number of students, as those who do not have the luxury of time could avail of such dynamic and effective education made very convenient to them sin ce it is not bound by normal school hours. Personal Opinion: How Technology will Shape Education in the Future Technology is evolving, as it is used in the field of education, so will the latter evolve, as well. Education will be better, as technology will constantly upgrade, so will the skills of the students. Thus, to keep up with complex learning needs brought about by modernized educational tools utilized by students, educators will adapt to such modernity. They will be well equipped with modern strategies to address learning needs. In the process, education will reach new heights. The standard of education would be further uplifted, producing more competitive

Rear Window Assignment Example | Topics and Well Written Essays - 250 words

Rear Window - Assignment Example The principal themes in Rear Window are voyeurism and the care for another person, in this case the person living in the apartment building opposite the rear window of James Stewarts place who got murdered. People should ideally not bother themselves with affairs of their neighbors and should mind only their own business but a broken leg left the principal actor played by James Stewart with nothing to do but sit the whole day in his apartment. There are three different analytical points (perspectives) to view this film and these are voyeurism, patriarchy, and feminist theory. Voyeurism is depicted by actor James Stewart as he spends all day watching his neighbors, in effect spying on them. A patriarchal approach is also a viable perspective because most of the human relationships shown in the film were about male and female relationship with the male always aiming for dominance. Feminism is also used because the women in the film were either mistreated or treated without respect at all or were generally put in a not flattering light for the movie audience. In the movie, the girlfriend of Stewart named Lisa was shown as a sexual object for the fantasy of male viewers; Lisa was obsessed with style and fashion to the point of narcissism (McCabe 25). The film maintained its ability to create fear and panic because the auteur Hitchcock understood very well the human psychology of the fear of getting murdered, the attractions of voyeurism, and the overall portrayal of most human relationships in everyday events. Its film director allowed the audience, in a sense, to know in advance what will happen next. A lack of special effects used in modern films allowed Rear Window to showcase the talents of a real auteur who can manage to bring a story to the audience without use of special effects. Sigmund Freud is mentioned frequently with Rear Window because of the meaning of his

Two Main Types Of Cells In Nervous System Biology Essay

Two Main Types Of Cells In Nervous System Biology Essay There are two main types of cells in the nervous system. These two types are neurons and neuroglia. A neuron is a nerve cell that transmits impulses of the nervous system. Three main parts make up a neuron: cell body, axon, and dendrite. The cell body of a neuron contains the nucleus and cytoplasm. The axon conducts impulses away from the cell body and is away from the cell body a single slender projection from the cell body. A dendrite sticks out off the cell body. It is shaped somewhat like a tree branch. Neuroglia is a type of connective tissue that supports the neurons. Neuroglia protects the nervous system instead of conducting impulses. Neuroglia use a process called phagocytosis to get rid of any unwanted substances. Neuroglia come in three types; astrocytes, microglia, and oligodendrocytes. Astrocytes are cells that possess many processes for attachment. Astrocytes are more plentiful than any other neuroglia, and are only present in the central nervous system. Astrocytes combined with the walls of a blood capillary, prevent harmful substances from passing from the blood to the brain. Microglia have branch like processes protruding from their bodies. The purpose of microglia is to remove debris, waste products, and pathogens from nervous tissue. Microglia increase in number when there is an injury or infection of the tissue. Oligodendrocytes have processes that protrude from their body and coil around axons. Oligodendrocytes main purpose is to be an electrical insulator and help speed the conduction of nerve impulses. #2 The peripheral nervous system contains twelve pairs of cranial nerves and thirty-one pairs of spinal nerves. The peripheral nervous system transmits sensory and motor impulses to and from the central nervous system and other parts of the body. The peripheral nervous system (PNS) is made of nerves. According to Comprehensive medical Terminology 3rd Edition by Betty Davis Jones, A nerve is a cord like bundle of nerve fibers that transmits impulses to and from the brain and spinal cords to other parts of the body. A nerve is macroscopic (i.e., able to be seen without the aid of a microscope). A ganglion is a knot like mass of nerve cell bodies located outside the CNS. The peripheral nervous system also has afferent and efferent nerves. Afferent nerves are sensory nerves that carry impulses from the body to the central nervous system. Efferent nerves are motor nerves that carry impulses from the central nervous system to the muscles and glands. Efferent nerves make the organs respond to a command by completing an action. There are two smaller nervous systems within the PNS called the somatic nervous system and the autonomic nervous system. The main difference between the somatic and autonomic nervous system is that the somatic nervous system is under voluntary control of the skeletal muscle contractions and the autonomic nervous system operates under involuntary control of the smooth and cardiac muscle as well as glandular activities and secretions. #3 The two main components of the central nervous system are the spinal cord and the brain. There is a protective membrane that surrounds the contents of the central nervous system. The membrane is made up of connective tissue called meninges as well as cerebrospinal fluid. The meninges are made up of three layers of membranes. The first layer is the dura mater. The dura mater is a tough white connective tissue. The second layer of the meninges is the arachnoid membrane. The arachnoid membrane is a thin layer of strands that connect to the innermost layer of meninges. The third layer is the pia meter. The pia meter is bound tightly to the surface of the CNS contents. #4 The brain, one of the organs found in the central nervous system can be divided into four sections. The first section is the cerebrum. The cerebrum controls consciousness, memory, sensations, emotions, and voluntary movements. The second section is the cerebellum. The cerebellum maintains muscle tone and coordinates normal movement as balance. The third section of the brain is the diencephalon which contains the thalamus, and the hypothalamus. The thalamus receives sensory stimuli and relays them to the cerebral cortex. The hypothalamus activates, controls, and integrates the peripheral autonomic nervous system, processes, and some sensory functions like body temperature, sleep, and appetite. The fourth and final section of the brain is the brain stem. The brain stem serves as a pathway for conduction of impulses between the brain and spinal cord. It controls such vital functions as respiration, blood pressure, and hear rate. (Davis Jones, 2008) #5 There are many pathological conditions that one may come across. Following will be a list of the just a few along with a description and treatment options for each. Anencephaly is where a child is born without a brain and spinal cord. It is a congenital disorder. A child born with this disorder cannot live. Anencephaly can be detected during pregnancy by the use of amniocentesis or ultrasonography. Carpal Tunnel Syndrome is pain caused by pinching or compressing of the median nerve. Inflammation and swelling of the tendons is what causes the pinching or compression. The pain of Carpal Tunnel Syndrome is the worst during the night. The inflammation associated with Carpal Tunnel Syndrome is caused by repetitious overuse of the fingers, hands, or wrists. There is a treatment for Carpal Tunnel Syndrome which includes taking anti-inflammatory medication, applying splints, attending physical therapy, and stopping the overuse. If these actions do not fix the problem, surgery may be necessary to relieve the pressure. A cerebral contusion is a bruise of the brain tissue that appears when the brain strikes the inner skull. Cerebral contusions cause swelling of the brain. Symptoms consistent with a cerebral contusion are combativeness, increased intracranial pressure, and altered levels of consciousness. Treatments for cerebral contusions are close observation, hospitalization, maintain cerebral perfusion, and administer corticosteroids, and osmotic diuretics. A headache or cephalagia is another pathological condition. Cephalagia is chronic to acute pain in the cranial cavity. A headache may be the result of a disease or other condition, but may also be benign. Treatment for headaches includes taking a mild analgesic. Petit mal seizures are a type of seizure where there is a sudden short time of unconsciousness. Unconsciousness associated with petit mal seizures last only a few seconds. Signs of a petit mal seizure are blank facial expression or repeated blinking for a short time. Most people suffering from petit mal seizures are small children prior to puberty. Peripheral neuritis is inflammation of one or more peripheral nerves. Other disorders are associated with peripheral neuritis such as trigeminal neuritis, Bells palsy, and carpal tunnel syndrome. Each disorder produces unique symptoms and has different treatments. Neuroblastoma is a malignant tumor in the sympathetic nervous system. Neuroblastoma occurs in the adrenal medulla and usually spreads to the liver, lungs, lymph nodes, and bone. Parkinsons disease is a slow deterioration of the nerves in the brain stems motor system. Signs and symptoms associated with Parkinsons disease are stooped posture, bowed head, shuffling gait, expressionless face, muffled speech, and difficulty swallowing. Treatment for Parkinsons disease is drug therapy, controlling the symptoms, and physical therapy. A surgical technique called a pallidotomy is sometimes used, but is not always successful. Shingles is a viral infection in adults who have had chicken pox. Shingles causes inflammation of the spinal or cranial nerve pathway. Symptoms commonly associated with shingles are server pain, fever, itching, GI disturbances, headache, general tiredness, and increased skin sensitivity. Treatment for shingles includes antiviral medications, analgesics, and corticosteroids. Spinal bifida cystic is a disorder in which the back part of one or more vertebrae is not normally closed. In this opening, cysts come through the fifth lumbar. There are tons of other pathological conditions a person may develop all of which have different symptoms, effects, and treatments.

Pushkins The Queen of Spades Essay -- Pushkin Queen of Spades Essays

Pushkin's The Queen of Spades French connoisseurs already know Pushkin's The Queen of Spades in Mà ©rimà ©e's translation. It might appear impertinent to offer now a new version, and I do not doubt that the earlier one will appear more elegant than this one, which has no merit other than its scrupulous exactness. That is its justification. A preoccupation with explaining and rounding off induced Mà ©rimà ©e to blunt somewhat the crystalline peaks of the tale. We have resisted adding anything to Pushkin's clean and spare style, with its slender grace, which hums like a taut string. When Pushkin writes: Herman quivered like a tiger, Mà ©rimà ©e adds: ... lying in wait. When he has Lisaveta bend over a book, Mà ©rimà ©e says gracefully. This charming writer thus marks his own manner, and if some criticize his dryness it is clear here that the criticism is ill-founded, or, at least, that only by comparison with the lush style of the writers of his period can Mà ©rimà ©e's style seem so unadorned to us. The clarity of Pushkin, on the other hand, chafes him, and nothing shows that better than a study of this translation. Poets, Pushkin wrote, often sin by neglect of simplicity and truth; they pursue all manner of external effects. The pursuit of form sweeps them toward exaggeration and bombast. He criticized in Hugo, whom he admired, an absence of simplicity. Life is lacking in him, he wrote. In other words, truth is absent. The strangeness of most Russian writers, including the greatest among them, often baffles the French reader, and indeed, sometimes repels him; but I confess that it is the absence of strangeness in Pushkin that confounds me. Or at least what baffles me, is to see that Dostoevsky, that genius so prodigi... ...offers us geniuses like Shakespeare, Cervantes, Schiller. But show me, even one among them all, who possesses to the same degree as Pushkin the capacity for universal comprehension. And again: Pushkin was the only one among the poets who succeeded in assuming the soul of other poets. But according to Dostoevsky it is to his profoundly Russian character that Pushkin owes his universality, for the mission of each Russian is doubtless a universal mission. ... To become truly a Russian, he adds, to become completely Russianmeans to feel oneself brother to all men. The Queen of Spades, that brief masterpiece, offers us an excellent example of the admirable poetic qualities of Pushkin and his gift for self-effacement. Work Cited Gide, Andre.

Major Political Parties in the United States

Today, the politics of the United States government is controlled by two dominant political parties: the Republican Party and the Democratic Party. These two political parties dominated US politics from 1860 to the present. This is not to say that the US electoral system does not allow the existence of a multiple party system. It should be noted that the development of a two-party system in the United States was due perhaps to the relative contradiction of ideology and platforms of government between these two parties.US voters historically perceived this difference as necessary because of the need to maximize the saliency of political choice. When one set of policies failed, the voters had the option of voting the policies of the other party. This is called polarization. Hence, an understanding of the ideology of each political party is needed. In 1854, anti-slavery politicians met at Ripon, Wisconsin to form the Republican Party. After a year, the party grew rapidly displacing the Whig Party as the primary opposition party to the Democratic Party.In 1859, it nominated Abraham Lincoln as president in the 1860 election. After the election of Abraham Lincoln, the party became a symbol of anti-slavery, and after the war, the period of Reconstruction. Early Republicans advocated the slogan ‘free labor, free land, and free men. ’ The Republican Party believed that class mobility is an important factor in economic development. According to Republican ideology, individuals have the right to determine their economic status, given economic circumstances. The party also advocated a countrywide redistribution of land.Early Republicans believed that giving away government-owned land would rapidly end slavery. From 1859 to 1865, the party was actively anti-slavery in the Western territories as a means to check the intentions of the Confederacy. After the Civil War, the party changed some of its political beliefs. It supported big businesses, the annexation of Hawaii, and generous pensions for Union veterans. With the rapid growth of the transportation and manufacturing sectors, the party advocated the implementation of a countrywide subsidy program and the imposition of higher tariffs on foreign goods.Today, the party advocates a Keynesian approach to economic development, emphasizing the need for the government to adjust its expenditures based on growth patterns. The party also supports lowering both the optimal tax rates and the general tariff rates as a means to boost the economy. Social welfare is deemphasized in present Republican ideology. The origin of the Democratic Party can be traced back to the party founded by Jefferson, Madison, and other politicians opposing the Federalists.The modern Democratic Party, however, was founded with the election of Andrew Jackson to the presidency. From 1860 to 1920, the party positioned itself to the left of the Republican Party on a number of economic, political, and social issues. The electio n of Woodrow Wilson revived the influence of the party in policy-making, after 30 years of political hibernation. In 1932, Franklin Roosevelt was elected president of the United States. His New Deal program increased the political base of the party, and became the economic framework of the US government until the 1970s.The ideology of the Democratic Party differs from that of the Republican Party in three respects. First, the party advocates social liberalism, emphasizing the institutionalization of affirmative action and social freedom. Second, the party believes in a free-enterprise system regulated by government intervention. Third, the party believes that the government should play a role in alleviating poverty and the use of progressive taxation. Democratic ideology asserts that ‘economic development is assumed to be a function of social progress. ’I learned that both the federal and state governments are governed by a system of checks and balances. The government is divided into three branches which are assumed to be equal in integrity and power. Both in federal and state governments, the legislatures act as the lawmaking body. The executive branch of government approves or vetoes legislations approved by Congress. The legislative branch approves the budget, reserves the right to declare war, and examines the operations of the government through committee hearings and investigations.These powers act as a check to the actions of the executive branch. The judicial branch of government reserves the power to examine the constitutionality of statutes passed by Congress. This is called ‘power of judicial review. ’ This power acts as a check to the legislative branch. It can also make recommendations to the federal government on issues of legality/constitutionality of specific government actions/policies. The members of the judicial branch are appointed by the president, with the concurrence of Congress.This serves as a check to the po wer of the judicial branch. Comments Regarding the Instructor, the Course, and Class Requirements The instructor is very efficient in giving information about the American government, pointing out salient issues and problems. The course is a good starting point towards a more deep and critical understanding of the history of the US government. Class requirements are by no means heavy. Much of the class requirements reflect the learning experience necessary for a full understanding of US politics and governance.

A detective story written by Conan Doyle Essay

Baskerville and his companions later on meet a friend, who tells the about a convicted murder called Seldon, escaping from prison and being loose upon the moor. Seldon is part of the atmosphere in Dartmoor. Seldon is described as being â€Å"fiendish† and having a heart full of â€Å"malignancy†, which links him to the Hound, a creature known to kill the Baskerville family. The hound is also loose in Dartmoor. The Hound and Seldon bring a menacing, and deadly atmosphere to Dartmoor. In the distance, clearly visible was a â€Å"mounted soldier† holding a â€Å"rifle†. The soldier is an example of the symbol used in the setting. Soldiers carrying rifles have connotations of dark, menace, and death. These descriptions together with the moor give a forbidding atmosphere, preparing readers for forthcoming, menacing events. Baskerville had travelled across Dartmoor, and now had an exterior view of Baskerville Hall. As he walked in he noticed the decaying gates made of granite. Granite has connotations of darkness, hard, and black, suggesting Baskerville has a dark decaying family. This is true, as he is the only Baskerville remaining. They later enter a tunnel, increasing the darkness of the atmosphere. â€Å"The house glimmered like a ghost†, suggests the supernatural, and death. This is symbolic for the death of those who lived in the house. The descriptive words â€Å"dark veil†, â€Å"dull light†, and â€Å"black granite† all indicate the darkness and gloominess of Baskerville Hall. This raises a sinister, forbidding, and menacing atmosphere. Baskerville adds to the frightening atmosphere by saying â€Å"its enough to scare off a man†. The walls of the rooms were made from age-blackened oak, which also suggests darkness, and adds to the menace of the atmosphere. Conan Doyle obviously intended the atmosphere of the book to be a menacing one, and he did an excellent job in my opinion. The excellent description of setting in his books is one of the reasons why his books are so popular.
