Are we dealing with new products resulting from technological change? If so, how will the new products impact the economic structure? One source of new technology is the search for increased economic efficiency and a sincere desire to reduce the cost that the society has to pay for the availability of goods. Whether the purpose of the technology is to improve its effective use of available natural resources or to increase or alter the supply of available resources, it will impact what people buy, what they choose to do with their time, what jobs are lost due to changes in the overall economic mix, and possibly the price of other goods that compete with the technologically changed function for raw materials, labor, and the limited capital resources that are available. As a secondary effect, how will the new technology create changes in unrelated or distantly related markets? The computer was a fantastic new technology. Indeed, it still is. The changes that have taken place in the business world reach far beyond the immediate impact anticipated. On the surface, it was not difficult to realize that the computer would affect the market for mechanical devices designed to do tasks that a computer does, such as adding machines, typewriters, or even automatic mechanical control mechanisms.

The Yellow Wallpaper And The Lottery Essay - 847 Words

In modern society, most traditions are viewed as customs that unify people, strengthening relationships between family, friends, and community. In contrast, Shirley Jackson and Charlotte Perkins Gilman blatantly exhibit how outdated traditions in history have severed relations amongst people, acting as divisive forces rather than unifying practices. In â€Å"The Yellow Wallpaper† and â€Å"The Lottery†, old traditions of the societies in the stories incite conflict amongst the characters, negatively influencing relationships between and within characters. In both short stories, it is evident that aged traditions possess the capability to construct barriers between the strong bonds existent in families. Traditions have the ability to turn†¦show more content†¦Her unforeseen actions are due to the rest care tradition, which has progressively worsened her mental state and caused her to overlook her role as a caring wife in desperation to escape the imprisonment of the tradition. As witnessed from the two short stories, conflicts arise amidst families due to the events of old traditions, establishing a divide between family members that is difficult to overcome once constructed. While outdated traditions obtain the ability to negatively impact the relationships between characters, they are also capable of creating internal conflicts within a character. In both texts, readers witness the effect traditions have on one’s morality, mental mind, and sense of identity. The occurrence of atrocious, old traditions plays a significant role in corrupting one’s morals, inducing conflict with a character’s past values. This is clearly exhibited when â€Å"Mrs. Delacroix selected a stone so large she had to pick it up with both hands† (51). The ritual itself of hurling stones at another human is a demoralizing act that should not be justified by society, and reveals her iniquitous and immoral traits as she lacks awareness of her dehumanizing actions amidst participating in the ceremony. Mrs. Delacroix picks a colossal stone amongst a variety of possible sizes, demonstrating her loss of morals and redefined focus on the power she obtains from t his abhorrent tradition.

Body Alterations Free Essays

Cosmetic surgery is the most common kind of plastic surgery nowadays. It consists on medical practices intended for enhancing one’s appearance, maintaining it or embellishing it beyond an average level toward an esthetic ideal. Tattoos, piercings and any other ornaments are applications that also take the human’s body as their final object. We will write a custom essay sample on Body Alterations or any similar topic only for you Order Now In his essay â€Å"The Body Jigsaw†, Philippe Liotard states that cosmetic surgery and body alterations stand at opposite sides. In the following, I’m going to take a position relatively to the above statement, before analyzing the situation in my home society, Lebanon. First of all, Liotard believes that body modifications are ways that one can use in order to look different from the common mass. For him, it is as expression of â€Å"refusal to comply with social norms† (Liotard, 264). So far, it’s true that having a foreign tattoo or a piercing in a society that doesn’t originally apply them commonly makes a person looks out of the box. Moreover, different combinations of body alterations emphasize the uniqueness of each individual and reflect a mixture of cultures. On the opposite side, cosmetic surgery can be applied for several reasons. One of them is looking for example as a certain idol, celebrity or any public figure. This aim is becoming very redundant between women who seek having this actress’ nose or that singer’s lips. From this way of thinking, we can say that cosmetic surgery promotes a kind of stereotype. For that, the uniqueness of each individual is abolished. For this way of interpretation, I stand on the same shore as the author. Moving to my home society, views and opinions concerning both â€Å"alternative† body alterations and cosmetic surgery vary a lot. There’s no single common way of handling these applications. In fact, some alterations are rejected while others can be tolerated. For most Lebanese, a familiar thought is that piercing as well as others body ornaments or some techniques are not manly. For that, a man with a pierced ear is subject to negative connotations. On the other hand, tattoos for instance are accepted to a certain extend. Concerning cosmetic surgery, we encounter three main categories of opinions. There are some people who completely support these surgeries whereas others reject them completely while some have intermediate views. As far as I’m concerned, I don’t mind people having a tattoo even though I won’t do it. I personally believe that the decision of having a permanent tattoo is based on mood or temporary convictions that can collapse with time. On the contrary, I’m not against having a temporary one. Also, about cosmetic surgeries, I support them when they aim to correct an inborn defect or an accidental one. A personal experience I had was when I broke my nose and the only solution was having a surgery to repair the bad appearance caused by the accident. On the opposite side, I disapprove plastic surgeries when they are applied just to have someone else’s nose, lips†¦ To sum up, I agree that cosmetic surgery and â€Å"alternative† body alterations are philosophical antonyms even though they both affect the body. And, like in everything else, the best use of body alterations relies in moderation. As a Lebanese proverb says: â€Å"Every excess means less† Works Cited Liotard, Philippe. â€Å"The Body Jigsaw†.

Electricity Essay Research Paper WHAT IS ELECTRICITYElectricity free essay sample

Electricity Essay, Research Paper WHAT IS ELECTRICITY Electricity is a signifier of energy. That # 8217 ; s because we can utilize electricity to make things for us, like run machines and computing machines. Electricity besides can be transformed into other types of energy such as heat or visible radiation and is used to heat our places, light our metropoliss and towns and power the computing machines we are utilizing. Electricity is the type of energy that is unseeable. It # 8217 ; s made of traveling negatrons that are so little and travel so fast that we can non see them. The electricity that GPU provides travels through the wires you see on tall poles and towers around your town or metropolis. Sometimes they go down in a fenced-off country that is full of big metal boxes, tonss of electrical wires, equipment and other material. These countries are called substations, and they change the power of electricity is before it gets to your place. Electricity is the motion of one million millions of negatrons. Electrons are one constituent of an atom. Atoms are the basic edifice blocks of all affair and are comprised on protons and neutrons in add-on to negatrons. The protons and neutrons of an atom are housed in the Centre of an atom called the karyon. Electricity is a phenomenon that is a consequence of the being of electrical charge. The theory of electricity and its inseparable consequence, magnetic attraction, is likely the most accurate and complete of all scientific theories. The apprehension of electricity has led to the innovation of motors, generators, telephones, wireless and telecasting, X-ray devices, computing machines, and atomic energy systems. Electricity is a necessity to modern civilisation. How is Electricity Produced? Electricity is a secondary beginning of energy that is created at a generating works. At the bring forthing station, primary beginnings of energy, which include coal, oil, gas, H2O, and air current, are converted to steam. This steam provides the power to turn the blades of a device known as a turbine. The steam turning the blades of a turbine is like the air current turning the blades of a windmill. The mechanical power created by the steam turning the turbine turns the shaft. The shaft so turns the generator. A generator contains a magnet surrounded by a spiral of wire. The motion of negatrons is called electric current. Electric Charge Amber is a xanthous, semitransparent mineral. Equally early as 600 BC the Greeks were cognizant of its curious belongings: when rubbed with a piece of pelt, amber develops the ability to pull little pieces of stuff such as plumes. For centuries this strange, incomprehensible belongings was thought to be alone to amber. Two thousand old ages subsequently, in the sixteenth century, William Gilbert proved that many other substances are electric ( from the Grecian word for gold, elektron ) and that they have two electrical effects. When rubbed with pelt, brownish-yellow acquires pitchy electricity ; glass, nevertheless, when rubbed with silk, acquires vitreous electricity. Electricity repels the same sort and attracts the opposite sort of electricity. Scientists thought that the clash really created the electricity ( their word for charge ) . They did non recognize that an equal sum of opposite electricity remained on the pelt or silk. In 1747, Benjamin Franklin in America and William Watson ( 1715-87 ) in England independently reached the same decision: all stuffs possess a individual sort of electrical # 8220 ; fluid # 8221 ; that can perforate affair freely but that can be neither created nor destroyed. The action of rubbing simply transfers the fluid from one organic structure to another, electrifying both. Franklin and Watson originated the rule of preservation of charge: the entire measure of electricity in an insulated system is changeless. Franklin defined the fluid, which corresponded to vitreous electricity, as positive and the deficiency of fluid as negative. Therefore, harmonizing to Franklin, the way of flow was from positive to negative # 8211 ; the antonym of what is now known to be true. A subsequent two-fluid theory was developed, harmonizing to which samples of the same type attract, whereas those of opposite types repel. Benjamin Franklin ( 1706-90 ) was an American pressman, writer, philosopher, diplomat, scientist, and discoverer. ( The Bettmann Archive ) Lightning Franklin was acquainted with the Leyden jar, a glass jar coated inside and outside with tin foil. It was the first capacitance, a device used to hive away charge. The Leyden jar could be discharged by touching the inner and outer foil beds at the same time, doing an electrical daze to a individual. If a metal music director was used, a flicker could be seen and heard. Franklin wondered whether lightning and boom were besides a consequence of electrical discharge. During a electrical storm in 1752, Franklin flew a kite that had a metal tip. At the terminal of the moisture, carry oning hemp line on which the kite flew he attached a metal key, to which he tied a nonconductive silk twine that he held in his manus. The experiment was highly risky, but the consequences were unmistakable: when he held his brass knuckss near the key, he could pull flickers from it. The following two who tried this highly unsafe experiment were killed. The Electrical Force It was known every bit early as 1600 that the attractive or abhorrent force diminishes as the charges are separated. This relationship was foremost placed on a numerically accurate, or quantitative, foundation by Joseph Priestley, a friend of Benjamin Franklin. In 1767, Priestley indirectly deduced that when the distance between two little, charged organic structures is increased by some factor, the forces between the organic structures are reduced by the square of the factor. For illustration, if the distance between charges is tripled, the force decreases to one-ninth its former value. Although strict, Priestley # 8217 ; s cogent evidence was so simple that he did non strongly recommend it. The affair was non considered settled until 18 old ages subsequently, when John Robinson of Scotland made more direct measurings of the electrical force involved. Coulomb # 8217 ; s Law The Gallic physicist Charles A. de Coulomb, whose name is used as the unit of electrical charge, subsequently performed a series of experiments that added of import inside informations, every bit good as preciseness, to Priestley # 8217 ; s cogent evidence. He besides promoted the two-fluid theory of electrical charges, rejecting both the thought of the creative activity of electricity by clash and Franklin # 8217 ; s single-fluid theoretical account. Today the electrostatic force jurisprudence, besides known as COULOMB # 8217 ; S LAW, is expressed as follows: if two little objects, a distance R apart, have charges p and q and are at remainder, the magnitude of the force F on either is given by F = Kpq/rr, where K is a changeless. Harmonizing to the International System of Units, the force is measured in Newtons ( 1 Newton = 0.225 pound ) , the distance in metres, and the charges in C. The changeless K so becomes 8.988 billion. Charges of opposite mark attract, whereas those of the same mark repel. A C C is a big sum of charge. To keep a positive C ( + C ) 1 metre off from a negative C ( Degree centigrade ) would necessitate a force of 9 billion Newtons ( 2 billion lbs ) . A typical charged cloud about to give rise to a lightning bolt has a charge of approximately 30 Cs. Electric Potential Because of an accident the 18th-century Italian scientist Luigi Galvani started a concatenation of events that culminated in the development of the construct of electromotive force and the innovation of the battery. In 1780 one of Galvani # 8217 ; s helpers noticed that a cleft toad leg twitched when he touched its nervus with a scalpel. Another helper thought that he had seen a flicker from a nearby charged electric generator at the same clip. Galvani reasoned that the electricity was the cause of the musculus contractions. He erroneously thought, nevertheless, that the consequence was due to the transportation of a particular fluid, or # 8220 ; carnal electricity, # 8221 ; instead than to conventional electricity. Experiments such as this, in which the legs of a toad or bird were stimulated by contact with different types of metals, led Luigi Galvani in 1791 to suggest his theory that carnal tissues generate electricity. ( The Bettmann Archive ) The Battery In experimenting with what he called atmospheric electricity, Galvani found that a frog musculus would jerk when hung by a brass hook on an Fe lattice. Another Italian, Alessandro Volta, a professor at the University of Pavia, affirmed that the brass and Fe, separated by the damp tissue of the toad, were bring forthing electricity, and that the toad # 8217 ; s leg was merely a sensor. In 1800, Volta succeeded in magnifying the consequence by stacking home bases made of Cu, Zn, and moistened pasteboard severally and in so making he invented the battery. A battery separates electrical charge by chemical agencies. If the charge is removed in some manner, the battery separates more charge, therefore transforming chemical energy into electrical energy. A battery can impact charges, for case, by coercing them through the fibril of a light bulb. Its ability to make work by electrical agencies is measured by the V, named for Volta. A V is equal to 1 J of work or energy ( 1 J = 2.78/10,000,000 kilowatt-hours ) for each C of charge. The electrical ability of a battery to make work is called the electromotive force, or voltage. The first electric battery, known as the Gur heap, was invented in 1800 by Alessandro Volta ( 1745-1827 ) . Voltaic piles consisted of a stack of jumping phonograph record of Zn and Cu or Ag separated by felt soaked in seawater. They provided, for the first clip, a simple beginning of stored electrical energy that didn # 8217 ; t trust on mechanical agencies. ( The Bettmann Archive ) The Capacitor Another device capable of electrical work is the capacitance, a descendent of the Leyden jar, which is used to hive away charge. If a charge Q is placed on the metal plates the electromotive force rises to amount V. The step of a capacitance # 8217 ; s ability to hive away charge is the electrical capacity C, where C = Q/V. Charge flows from a capacitance merely as it flows from a battery, but with one important difference. When the charge leaves a capacitance # 8217 ; s plates, no more can be obtained without reloading. This happens because the electrical force is conservative. The energy released can non transcend the energy stored. This ability to make work is called electric potency. A type of preservation of energy is besides associated with voltage. The electrical energy gettable from a battery is limited by the energy stored in chemical molecular bonds. Both voltage and electric potency are measured in Vs, and, unluckily, the footings electromotive force, possible, and voltage are used instead slackly. For illustration, the term battery potency is frequently used alternatively of voltage. Voltage Whether as an voltage or an electric potency, electromotive force is a step of the ability of a system to make work on a unit sum of charge by electrical agencies. Voltage is a better-known measure than electric field. For case, electromotive forces measured in an electrocardiogram extremum at 5 mVs ; many are familiar with the 115-volt potency of a house. The possible between a cloud and the land merely before a typical lightning bolt is a lower limit of 10,000 Vs. Sometimes high electromotive forces are needed. For case, the negatron beams in telecasting tubings require more than 30,000 Vs. Electrons # 8220 ; falling # 8221 ; through such a possible range speeds every bit high as one-third the velocity of visible radiation and have sufficient energy to do a topographic point of visible radiation on the screen. Such high potencies may be developed from lower jumping potencies by utilizing a transformer. By draging places on a rug on a dry twenty-four hours, an electric potency of more than 20,000 Vs can be developed, ensuing in a flicker. Electric Current An electric charge in gesture is called electric current. The strength of a current is the sum of charge go throughing a given point ( as in a wire ) per second, or I = Q/t, where Q C of charge base on balls in t seconds. The unit for mensurating current is the ampere or amp, which equals 1 coulomb/sec. Because it is the beginning of magnetic attraction as good, current is the nexus between electricity and magnetic attraction. In 1819 the Danish physicist Hans Christian Oersted found that a compass acerate leaf was affected by a current-carrying wire. Almost instantly, Andre Ampere in France discovered the magnetic force jurisprudence. Michael Faraday in England and Joseph Henry in the United States added the thought of magnetic initiation, whereby a altering magnetic field produces an electric field. The phase was so set for the embracing electromagnetic theory of James Clerk Maxwell. The fluctuation of existent currents is tremendous. A modern electrometer can observe currents every bit low as 1/100,000,000,000,000,000 A, which is a mere 63 negatrons per second. The current in a nervus urge is about 1/100,000 As ; a 100-watt visible radiation bulb carries 1 A ; a lightning bolt extremums at about 20,000 As ; and a 1,200-megawatt atomic power works can present 10,000,000 As at 115 V. Most stuffs are dielectrics. In them, all negatrons are bound in single atoms and do non allow a flow of charge unless the electric field moving on the stuff is so high that breakdown occurs. Then, in a procedure called ionization, the most slackly bound negatrons are torn from the atoms, leting current flow. This status exists during a lightning storm. The separation of charge between the clouds and the land creates a big electric field that ionises the air atoms, thereby organizing a carry oning way from cloud to land. Resistance Although a music director permits the flow of charge, it is non without a cost in energy. The negatrons are accelerated by the electric field. Before they move far, nevertheless, they collide with one of the atoms of the music director, decelerating them down or even change by reversaling their way. As a consequence, they lose energy to the atoms. This energy appears as heat, and the sprinkling is a opposition to the current. In 1827 a German instructor named George Ohm demonstrated that the current in a wire increases in direct proportion to the electromotive force V and the cross-sectional countries of the wire A, and in reverse proportion to the length I. Because the current besides depends on the peculiar stuff, Ohm # 8217 ; s jurisprudence is written in two stairss, I = V/R, and R = pI/A X the electric resistance. The measure R is called the opposition. The electric resistance depends merely on the type of stuff. The unit of opposition is the ohm, where 1 ohm is equal to 1 volt/amp. Certain stuffs, such as lead, lose their opposition about wholly when cooled to within a few grades of absolute nothing. Such stuffs are called superconductors. Substances have late been found that become ace conductive at much higher temperatures. The resistive warming caused by negatron sprinkling is a important consequence and is used in electric ranges and warmers every bit good as in incandescent visible radiation bulbs. In a resistance the power P, or energy per second, is given by P = ( I squared ) R. Speed of Electricity As negatrons bounciness along through the wire, the general charge impetus constitutes the current. The mean, or impetus, velocity is defined as the velocity the negatrons would hold if all were traveling with changeless speed analogue to the field. The impetus velocity is really little even in good music directors. In a 1.0-mm-diameter Cu wire transporting a current of 10 As at room temperature, the impetus velocity of the negatrons is 0.2 millimeter per second. In Cu, the negatrons seldom drift faster than one hundred-billionth the velocity of visible radiation. On the other manus, the velocity of the electric signal is the velocity of visible radiation. This means that, at the velocity of visible radiation, the remotion of one negatron from one terminal of a long wire would impact negatrons elsewhere. For illustration, see a long, inactive cargo train, with the autos stand foring negatrons in a wire. Because the yokes between autos have play in them, the galley is affected a short piece after the engine begins traveling. During this clip the engine moves frontward a short distance. The signal stating the galley to get down moves rearward rapidly, going the length of the train in the same clip it takes the engine to travel frontward a metre or so. Similarly, the negatron impetus velocity in a music director is low, but the signal moves at the velocity of visible radiation in the opposite way. Electrical Theory of Matter The possibility that electricity does non dwell of a smooth, uninterrupted fluid likely occurred to many scientists. Even Franklin one time wrote that the # 8220 ; fluid # 8221 ; consists of # 8220 ; atoms highly sub tile. # 8221 ; However, a great trade of grounds had to be accumulated before the position was accepted that electricity comes in bantam, distinct sums, looking non at all like a fluid when viewed microscopically. James Clerk Maxwell opposed this atom theory. Toward the terminal of the 1800s, nevertheless, the work of Sir Joseph John Thomson ( 1856-1940 ) and others proved the being of the negatron. The Electron Thomson had measured the ratio of the electron # 8217 ; s charge to its mass. Then in 1899 he inferred a value for the electronic charge itself by detecting the behaviour of a cloud of bantam charged H2O droplets in an electric field. This observation led to Millikan # 8217 ; s Oil-Drop Experiment. Robert Millikan, a physicist at the University of Chicago, with the aid of his pupil Harvey Fletcher, sought to mensurate the charge of a individual negatron, an ambitious end in 1906. A bantam droplet of oil with an surplus of a few negatrons was formed by coercing the liquid through a device similar to a perfume atomiser. The bead was so, in consequence, suspended, with an electric field pulling it up and the force of gravitation drawing it down. By finding the mass of the oil bead and the value of the electric field, the charge on the bead was calculated. The consequence: the negatron charge vitamin E is negative and has the value e = 1.60/10,000,000,000,000,000,000 C. This charge is so little that a individual Cu penny contains more than 10,000,000,000,000,000,000,000 negatrons. Robert Millikan ( 1868-1953 ) won the 1923 Nobel Prize in natural philosophies for his work on the simple electric charge and on the photoelectric consequence. He besides did much work on cosmic beams, which he named. He is seen here ( right ) in his cellar with his helper and his self-recording electroscope. Under Millikan # 8217 ; s leading the California Institute of Technology rapidly developed into one of the foremost scientific centres in the universe. ( The Bettmann Archive ) Millikan besides found that a charge ever appears to be in exact whole number multiples of plus or minus vitamin E ; in other words, the charge is quantized. Other simple atoms discovered subsequently were besides found to hold a charge of plus or minus e. For illustration, the antielectron, discovered in 1932 by Carl David Anderson of the California Institute of Technology, is precisely the same as the negatron, except that it has a charge of +e. Atomic Structure Bulk affair is usually impersonal. The inclination is for every positive proton in an atom to be electrically balanced against a negative negatron, and the amount is every bit close to zero as anyone has been able to mensurate. In 1911, Ernest Rutherford proposed the atomic atom. He suggested that negatrons orbit a positively charged nucleus less than 1/100,000,000,000,000 metres in diameter, merely as planets orbit the Sun. Rutherford besides suggested that the karyon is composed of protons, each holding a charge +e. This position of affair, still considered correct in many ways, established the electrical force as that which holds an atom together. After Rutherford presented his atom, the Danish physicist Niels Bohr proposed that the negatrons have merely certain orbits about the karyon, that other orbits are impossible. Quantum Theory Early on in the twentieth century the quantum theory was developed. Harmonizing to this theory, the negatron is a smeared cloud of mass and charge. In some state of affairss the negatron cloud might be so little that the atom appears to be much like the bantam, charged marble of earlier positions. In other state of affairss, such as when the negatron is in an atomic orbit, the cloud is many times larger. In 1963, Murray Gell-Mann and George Zweig of the California Institute of Technology proposed a theory harmonizing to which the electronic charge vitamin E might non be the cardinal charge after all. In their theory, heavy atoms such as protons and neutrons consist of assorted combinations of atoms called quarks. One quark is supposed to hold charge ( -1/3 ) vitamin E and another ( -2/3 ) e. This theory has prompted a major hunt for quarks. Bron: 31e

Latin America Affected by Illegal Drugs

Latin America is the region worse affected by illegal drugs. Countries such as Mexico and Uruguay act as producers and suppliers of a number of illicit drugs to the international illegal drug market. The aggressive war on drugs waged by the Latin American states has failed to yield significant results and the drug problem continues to plague the region.Advertising We will write a custom essay sample on Latin America Affected by Illegal Drugs specifically for you for only $16.05 $11/page Learn More This has led to radical actions being proposed by Latin American leaders. Uruguay’s president Josà © Mujica has proposed for a government regulated and controlled marijuana market while Mexican President Felipe Calderon has called for a new way to reduce trafficking considering the fact that developed countries have been unable to reduce their consumption of illegal drugs. President Calderon argued that criminal networks had massive resources due to the lack of international action by the drug consuming countries to tackle the issue (UN General Debate, 2012). Both leaders contend that legalization of drugs might be the solution to the drug problems that has plagued Latin America for decades. The argument made by the Latin American leaders fails to consider the adverse effects of drugs on the user. Drug use results in physical and mental effects and increases instances of violence. The UAE is strongly against illegal drugs and harsh penalties are imposed on individuals possessing or trafficking these drugs. This stringent approach is based on the understanding that drugs threaten social stability by promoting violence and making people economically inactive. The UAE perspective would therefore be against the proposed legalization of drugs since such measures would result in more harm than good. This argument is supported by Yacoubian (2007) who reveals that heavy marijuana use impairs a person’s ability to form memories and it might result in acute psychosis. Making the drug legal as the Uruguayan president proposes would result in more people suffering from the adverse mental and physical effects associated with drug use. Another argument made is that legalizing drugs such as Marijuana would have the positive effect of reducing trafficking. The Uruguayan president argues that legalization would give government greater control on the product, which would make it safer for the user while at the same time making the role of traffickers’ obsolete (Cave, 2012).Advertising Looking for essay on international relations?

Get your first paper with 15% OFF Learn More While this might be the case, marijuana is mostly a get way drug and most users move on to harder drugs such as heroin and cocaine. Making the drug legal would therefore lead to a significant increase in the number of people who are addicted to hard drugs. The UAE perspective would be against such a move since increased drug use is an undesirable outcome for the nation. The international community must take decisive action to tackle the issue of illegal drugs. However, this action should not be legalizing the consumption of currently illegal drugs. If the leaders in Latin America are earnest about their efforts to reduce drug trafficking, they should concentrate on eradicating corruption among local authority officials and improve the economic standards of their citizens. These are the two factors that have guaranteed the survival of drug cartels and traffickers and dealing with them will significant reduce the drug problem in the region. In the mean time, the leaders should adopt the UAE approach that views drugs as an ill to be eradicated at all costs for the good for the society. References Cave, D. (2012).

Hoi Polloi

Hoi Polloi Hoi Polloi Hoi Polloi By Maeve Maddox A reader has asked me to write about the word hoi polloi: I get so tired of intelligent people using this to mean the exact opposite. Hoi polloi is an English word that derives from a Greek phrase meaning â€Å"the many† or â€Å"the majority [of citizens].† Its English meaning is â€Å"the masses† or â€Å"the general public.† It’s often used in the pejorative sense of â€Å"the vulgar, unthinking masses.† The error the reader has in mind is the spreading tendency of many speakers (including intelligent ones) to use hoi polloi as if it means, â€Å"the social elite† or â€Å"influential rich people.† For example, So it’s official: Hollywood’s hoi polloi (e.g. Miramax movie mogul Harvey Weinstein) are coming out against firearms ownership and swearing off movies that rely heavily on gunplay. As Harvey Weinstein has a net worth of $200 million, the writer apparently believes that hoi polloi means â€Å"influential rich people.† In ancient Greek, hoi polloi meant â€Å"the many.† Its complementary term was hoi oligoi, â€Å"the few.† The term reflected a fact of social and political division. From the Greek word oligoi, we get the English word oligarchy, â€Å"government by a small group of people.† Classical scholar John Dryden introduced the expression into English in 1668. For him, the hoi polloi were people who lacked literary discernment. The expression quickly became a useful way for speakers to distinguish â€Å"Us† from â€Å"Them.† Because â€Å"Us† is always more educated and informed than â€Å"Them,† hoi polloi came to mean â€Å"the uneducated majority† or â€Å"the great unwashed, vulgar, unthinking public.† Nowadays, although political power still belongs to the hoi oligoi, the hoi polloi are better educated than they were in Dryden’s time, and they don’t like being called hoi polloi. They also possess a power that earlier generations lacked: the power to redefine words. One factor contributing to the association of hoi polloi with â€Å"snooty rich people† could be the similarity with â€Å"hoity toity,† an expression that conveys contempt for someone seen as â€Å"putting on airs.† The two expressions are often juxtaposed for humorous effect, as in the title of the Roseanne episode called â€Å"Hoi Polloi Meets Hoiti Toiti† (Roseanne, Season 9, Episode 8). In this episode, Roseanne and her family visit â€Å"uppity-high-society people† on Martha’s Vineyard. Although wealthier and more refined in manners and speech than the Conners, the wealthy Wentworths are clearly their moral inferiors. Note: Roseanne is a television comedy series featuring a working class family, the Conners, who are portrayed as being vulgar in speech and manners, but morally superior to better-educated, more affluent characters they encounter. Another factor contributing to the shift in meaning of hoi polloi may be that the referent is not always clear from context. For example, in a Three Stooges episode called â€Å"Hoi Polloi,† a well-dressed man bets a colleague that he can take a man from â€Å"the lowest strata of society† and turn him into a gentleman. He experiments with the Stooges. He fails to civilize them, but the fancy people descend to the Stooges’ brutish behavior. At episode end, Moe looks disdainfully at the crowd of elegantly dressed men and women who are slapping, punching, and gouging one another and says, â€Å"This is our punishment for associating with the hoi polloi.† New meanings of hoi polloi include, â€Å"people who are not like us,† â€Å"people we don’t like,† and simply, â€Å"people who don’t know what we know.† For example, in a forum for equestrians, a member referred to people who are ignorant of the rules of dressage as â€Å"the hoi polloi.† The definition of hoi polloi in The Urban Dictionary indicates the aversion in which this word is held: hoi polloi: A stupid term used by pseudo intellectuals with unjustified superiority complexes. Many bloggers ridicule speakers who precede hoi polloi with the definite article: Clearly Lois is using words though ignorant of their meaning. â€Å"Hoi† is the definite article, meaning â€Å"the†. When the uneducated Lois says â€Å"the hoi polloi† she is saying â€Å"the the many†. She makes a fool of herself on many levels. Dryden knew that â€Å"hoi† means â€Å"the† in Greek. He even wrote the expression in Greek letters, confident that his target audience could read it. However, because he was using the word in an English sentence, he introduced it with the English definite article: â€Å"If by the people you understand the multitude, the ÃŽ ¿Ã¡ ¼ ± πΠ¿ÃŽ »ÃŽ »ÃŽ ¿Ã¡ ½ ¶.† Suggesting that English speakers who say â€Å"the hoi polloi† are â€Å"ignorant† may bathe critics in feelings of superiority, but the criticism is itself a sign of absurd pedantry and, dare I say, ignorance of how language works. Many English words incorporate a foreign element that means the without raising questions of tautology. For example, the al in algebra, alchemist, and Alcatraz â€Å"mean† the in Arabic. No one suggests that writing â€Å"the alchemist† is the same thing as writing â€Å"the the chemist.† As far as I know, no one ridicules people who refer to the La Brea tar pits in Los Angeles for â€Å"really† saying â€Å"the the tar tar pits.† (La and Brea are Spanish for the and tar.) Hoi polloi is an English word in transition. English speakers will determine whether the word retains the meaning of â€Å"the masses,† morphs into a term for â€Å"snooty rich people,† or falls to the wayside along with other words that usage has voted out as being culturally offensive.

Constructivism and Teaching English Assignment Example | Topics and Well Written Essays - 3000 words

Constructivism and Teaching English - Assignment Example Although constructivism might provide a model of knowing and learning that has important implications for classroom practices, it does not translate neatly into a set of pedagogical practices. The implementation of the constructivist approach is still worth discussion and clarification. This paper will highlight challenges associated with implementing constructivism in teaching English to speakers of other languages. Much writing has been done about theories of constructivism and the connection to superior learning results; however, there is no "consolidated" discussion of the foundations, results, and practical issues of constructivism. According to Marlowe and Page (1998), even when teachers recognise the value of and want to use constructivist approaches in their classrooms, their efforts often produce less than what they expected. There have been attempts to make constructivism operational so that classroom teachers can more rapidly apply constructivist theory to practice. The pr oblem is that the application of constructivism in classrooms is "neither widespread nor systematic". Constructivist propositions can seem fairly simple but hundreds of observations of and questions from pre-service and in ¬ service teachers over the past 10 years show that they are not. Teachers and administrators who already work with constructivist reform initiatives need guidelines to help with the implementation. Moreover, development of a constructivist view of learning as a basis for instruction implies fundamental changes.

Developmental Timeline Essay Example | Topics and Well Written Essays - 500 words

Developmental Timeline - Essay Example The final stage is the formal operational stage and this stage goes from the age of 12 and ends at death. In this stage, children can think articulately about concrete objects and they have a strong sense of reasoning. There are also substages to these stages. The first substage to the sensorimotor stage is from the ages of birth to one month and it occurs through reflexes like grasping and sucking. In this stage knowledge is acquired through these reflexes. Substage 2 happens from the ages of 1 to 4 months. Reflexes are organized into larger more complex behaviours where behaviours like grabbing a rattle to suck occurs. Substage 3 occurs from the ages of 4 to 8 months where repetition of actions causes pleasing or interesting things to happen as in the case of banging a rattle. Substage 4 occurs from the ages of 8 to 12 months. This occurs when objects can be imagined with the mind even when they are out of sight. Substage 5 occurs from the ages of 12 to 18 months where an object is used in a variety of ways. For example, banging a spoon against a high chair.

Stages of Child Language Acquisition

Stages of Child Language Acquisition A child starts to communicate with those around him/her since birth, although in the first few months this communication occurs on a non-verbal level. However, as a child develops physically, he/she gradually acquires language skills. Overall, child language acquisition begins from phonological development and proceeds to syntactic and semantic development. The aim of the present essay is to analyse three major stages of the first language acquisition (phonological, syntactic and semantic). Although linguists and other scholars have agreed in opinion that language is a process of acquisition (rather than the process of learning), they provide contradictory theories of child language acquisition (Cole Cole, 1996). Among the most famous theories are a reinforcement theory, an imitation theory, a critical-age theory and an analogy theory. Despite the fact that all these theories present a valid explanation of language acquisition, certain problems occur when they are applied to practic e. The most likely interpretation of phonological, syntactic and semantic development of a child is provided by imitation and analogy theories; hence, these theoretical concepts are employed for the analysis. According to these theories, the process of child language acquisition is aimed at adjusting to adults’ speech that has its rules and structures. As acquisition of language is a rather intricate process, a child only listens to adults’ speech in the first few months. Actually, in this period a child is involved in the process of language perception rather than the process of language production (See Table 1). However, as a child reaches the age of 6 months, he/she starts to pronounce various sounds (Fee, 1995). At first a child pronounces vowel sounds and further he/she manages to unite vowels and consonants (e.g. sa, da, ma, ba, di, ti, gu, etc.). At approximately 8 months a child constantly repeats syllables (e.g. ba-ba-ba or di-di-di) and by 12 months he/she successfully combines these syllables into a simple word (e.g. â€Å"mama†, â€Å"papa† or â€Å"baba†). It is significant that child’s pronunciation of sounds also reflects intonation and stress; according to Echols and Newport (1992), through these patterns a child makes an attempt to impart certain meaning or reveal his/her emotions . This babbling is the initial step in child’s phonological development (Macken, 1995); the true phonological skills are exposed by a child at approximately 1.4 years (though even at the age of 0.4 – 0.9 months a child already has some phonological abilities, as he manages to recognise native and non-native speech). At this time a child demonstrates comprehension of the relation between sounds and meanings; moreover, he/she starts to identify phonemic differences in adult speech. In the process of sound production a child certainly makes pronunciation mistakes that linguists regard as phonological deviations. Generally, phonological deviations are divided into two basic categories: substitution errors and syllable errors (Bankson Bernthal, 1998). Further, these categories are divided into several sub-categories, including weak syllable deletion, final consonant deletion, consonant cluster reduction, velar fronting, palatal fronting, stopping, gliding of liquids, word final devoicing, etc. Due to an immature speech apparatus, some sounds are more complex for child’s pronunciation than others; for instance, such consonant sounds as â€Å"l† and â€Å"r† are learned by a child later than sounds â€Å"p† and â€Å"m†, because the former sounds are phonetically similar, while the latter sounds are different. As a result, a child substitutes voiceless sounds with voiced sounds (e.g. â€Å"gap’ instead of â€Å"cap† or â€Å"tad† instead of â€Å"dad†); it is context sensitive voicing. The second deviation is word final devoicing; it is a process when final voiced consonants are substituted with voiceless consonants (â€Å"dad’ is pronounced as â€Å"dat†). A child may also employ final consonant deletion, pronouncing â€Å"co† instead of â€Å"cow† or â€Å"pin† instead of â€Å"pink†. Velar fronting (e.g. â€Å"tiss† instead of â€Å"kiss†) and palatal f ronting (e.g. â€Å"sake† instead of â€Å"shake†) are used by a child, because it is easier for him/her to pronounce consonants that are at the front of the mouth and teeth. Other phonological deviations include weak syllable deletion (â€Å"pape† instead of â€Å"paper†), consonant harmony (â€Å"goggy† instead of â€Å"doggy), cluster reduction (â€Å"tool† instead of â€Å"stool†), stopping (â€Å"pan† instead of â€Å"fan†) and gliding of liquids (â€Å"wat† instead of â€Å"rat). In reality, as Maye, Werker Gerken (2002) demonstrate in their research, a child perceives accurate phonemic contrasts, but he/she is unable to produce correct sounds until a proper age. Moreover, unlike adults, an infant may even distinguish foreign phonemic contrasts from native contrasts; due to this ability a child who is adopted in a foreign country may easily acquire language of his/her parents. At the age of 3-4 years most children learn to rightfully pronounce all sounds, eliminating the majority of phonological deviations. However, some children may continue to employ these deviations in their speech; specialists regard these children as individuals with certain phonological disorders that may have a detrimental effect on their reading skills (Ingram, 1989). When a child learns how to pronounce simple words, he/she proceeds to combine known words into small utterances. In this respect, a child acquires syntactic skills that are usually developed in two stages: the holophrastic stage and the two-word stage. During the holophrastic stage (between 0.9 and 1.0 years) a child forms one-word utterances with a certain intonation. In general, these utterances are composed of either verbs or nouns, while adjectives and other parts of speech are acquired by a child afterwards. In fact, it is rather difficult for adults to interpret child’s one-word sentences, as, for instance, â€Å"book† may mean that he/she wants his/her parents to read a book or that he/she sees a book or that he/she does not like this book. The situation is even more complicated when a child pronounces a phrase without intervals. According to O’Grady (1997), â€Å"many children initially treat what’s that? look at that, come here, and similar expre ssions as single units that are linked holistically to a particular situational context† (p.13). In other words, if a child hears phrases that are somehow stressed, he/she may extract them from the rest of speech and use them as a single entity, making no pauses among words. In the two-word stage (1.5-2.0 years) a child creates two-word sentences that are pronounced with single intonation and start to reflect the first semantic relations, for instance, â€Å"baby read† or â€Å"sit table† (Pinker, 1994). In general, these utterances are categorised as follows: 1) Noun Utterances: My apple, His Daddy. 2) Verb Utterances: Me play, Girl sing. 3) Questions: Mom read? Baba go? 4) Negatives: Not eat, No shirt. As the examples show, though these sentences are not grammatically right yet, they are constructed in a right order (Ingram, 1989). By the age of 2-3 years a child easily produces several thousand syntactic utterances, and the major stress in these utterances is placed on the word that provides more information (e.g. â€Å"Mummy COME† or â€Å"MUMMY come†). Initially, these sentences lack such function units as â€Å"on†, â€Å"the† or â€Å"of† and such inflections as â€Å"-s†, â€Å"-ing† or â€Å"-ed† (hence, child’s speech at this stage is usually regarded as â€Å"telegraphic speech†), but gradually a child includes negations, passives, comparatives, relative clauses and conjunctions in his/her sentences. In some cases a child may use right patterns and wrong patterns in one sentence, for instance, I reading and Mama is cooking. Such a combination reveals that a child knows certain grammar patterns, but he/sh e has not mastered them yet. However, if an adult uses these patterns incorrectly, he/she will obviously point at the mistake. As a child acquires knowledge of such a pattern as â€Å"-ed†, he/she usually turns to overregularisation, that is, a process when all verbs become regular in child’s speech (e.g. â€Å"goed† or â€Å"spended†). This overregularisation can be explained by the fact that a child acquires a language in certain patterns and, as he/she learns the pattern (e.g. â€Å"mama helped† or â€Å"baba claimed†), he/she applies this pattern to other verbs, including irregular verbs. It is certainly easier for a child to apply â€Å"-ed† to all verbs than to memorise all irregular verbs and differentiate regular verbs from irregular verbs. As the time passes, a child learns to change the wrong verb form for a right form. In addition, he/she gradually acquires knowledge of definite and indefinite articles, plural nouns, linkin g verbs and possessive cases. However, even when a child acquires knowledge of all these rules and patterns, he/she may still be unable to form complex utterances; consequently, a child may turn to the repetition of certain phrases to fill gaps in his/her speech. Finally, as a child manages to create simple sentences, he/she acquires semantic skills (approximately 3.0 years). As word acquisition intensifies, a child collides with a necessity to form semantic patterns; above all, a child uses those content categories that refer to objects, events and humans, although usage of these categories greatly depends on social, cultural and linguistic aspects. However, in all cultures a meaning that a child puts into a certain object or an utterance differs from a usual adult speech. As Harris (1990) states, young children â€Å"are able to express complex meanings, although these meanings are concerned with the current interests and needs, rather than abstract concepts or events that are distant in terms of time or space† (p.4). If a child mainly interacts with his/her peers, then he/she adjusts language to this childish realm. As a rule, a child employs either overgeneralisation or underextension when he/she creates semantic patterns. As for the first process, a child provides a word with more meanings than the word has; for example, he/she may apply the word â€Å"fox† to different animals. In the case of underextension, a child uses fewer meanings than a word has in a usual vocabulary; for example, he/she may associate a word â€Å"arm† only with a mother who touches him/her. In other instances a child fails to recognise a word. Besides, if a child can not find an appropriate word during speech, he/she may devise completely new words with new meanings. However, as a child grows and interacts with people in different situations, he/she learns more meanings of words and utterances (Beals Tabors, 1995). This especially regards interactions with adults; as adult speech is more sophisticated, a child memorises unknown patterns and then employs them in his/her speech. Hence, as a child acquires words and phrases with a profound semantic content, he/she gradually eliminates less semantically valid patterns. According to Frawley (1992), a child’s early semantic patterns reflect the following semantic categories: Agent and Action Cat run Agent and Object Girl doll Entity and Locative Baba far Attribute and Entity Wet hair Agent and Location Mother bath Action and Recipient Give birdie Possessor and Possession Papa pen But as a child shapes linguistic skills (3.5–4.0 years), he/she starts to employ more semantic categories, such as number, time, colour, substance, shape, position, etc., for instance, â€Å"Mummy and I went to a playground†, â€Å"My doll cries and I calm her† or â€Å"I give it to you†. Mastering the major concepts of grammar/meaning relations, a child manages to gradually employ complex grammar patterns: negatives: shouldn’t, needn’t, couldn’t; when-questions (as well as what and why): When do you go? tag-questions: You will go with me, will you? be + verb + -ing: Is Mummy Cooking? compound utterances: Papa is working and I am playing. if sentences: I will do if I wish. Thus, analysing child language acquisition, the essay suggests that from 6 months to 4-5 years a child gradually acquires phonological, syntactic and semantic skills. Although every child develops individually, language acquisition reflects common stages of speech perception and production. Some researchers (e.g. Pinker, 1994; O’Grady, 1997) claim that syntactic and semantic development of a child occurs simultaneously. The fact is that meanings of some verbs can not be understood by a child merely from a context; it is the knowledge of syntactic patterns that provides a child with an opportunity to rightfully uncover the meaning of these verbs. Whether this viewpoint is valid or not, it is absolutely clear that while a child has inborn abilities for language, he/she needs specific social environment to acquire it. This became especially obvious with a discovery of Amala and Kamala, the feral children who were brought up with wolves and could not speak at all. Such findings ce rtainly refute an innate hypothesis and reveal that linguistic skills of a child are formed by and within society. Table 1. Stages of Child Language Acquisition* Phonology From birth to 0.5 years – perception of adult speech; 0.6 years – pronunciation of the first sounds (vowels → consonants → vowels + consonants); 0.8 years – repetition of syllables and recognition of phonemic differences; 1.0 year – understanding of the relation between sounds and meaning; Use of phonological deviations: 1.4 years cluster reduction 2 years – weak syllable deletion initial consonant deletion final consonant deletion 2.0-3.0 years – palatal fronting velar fronting stopping gliding of liquids Syntax 0.9–1.0 years – â€Å"the holophrastic stage† – formation of one-word utterances; 1.5-2.0 years – â€Å"telegraphic speech†, formation of two-word utterances; 2.0–3.0 years – overregularisation of grammar Semantics 3.0 years – application of meaning to language patterns and grammar structures; Use of either overgeneralisation or Underextension Use of the following semantic categories: 1) Agent and Action 2) Agent and Object 3) Entity and Locative 4) Attribute and Entity 5) Agent and Location 6) Action and Recipient 7) Possessor and Possession 3.5-4.0 years – knowledge of complex grammar patterns: negatives; when-questions; tag-questions; be + verb + -ing; compound utterances; if sentences * The ages of child’s language development are approximate; the data in this table are generalised, while every child acquires phonological, syntactic and semantic skills on an individual basis. However, such a generalisation is important, as it allows specialists to reveal any deviations from the normal development of children. Bibliography Bankson, N. Bernthal, J.

But recently, linguists and researchers have recognised a great variety of semantic roles (or theta roles) that provide valid information as to grammar/meaning relations (Cutrer, 1993). According to Payne (1997), a semantic role is a specific role that is classified in accordance with its meaning and is performed by a participant with regard to the principal verb of an utterance. In other words, semantic roles provide an opportunity to identify either similarities or dissimilarities of verb’s meanings in sentences. Actually, some semantic roles are regarded as principal, while others are thought to be less crucial for a linguistic analysis. But, as Langacker (1991) points out, â€Å"there is no unique or exclusive set of role conceptions. Those cited as archetypal are analogous to the highest peak in a mountain range: they coexist with others that m ay be significant despite their lesser salience† (p.237). The major semantic roles include Agent, Patient, Instrument, Theme, Cause, Experience, Goal, Benefective (or Beneficiary), Source, Location, Temporal and Path (Jackendoff, 1990; Dowty, 1991). According to Van Valin (1999), semantic relations may be also divided into two groups: the first group includes the usual semantic roles, such as Agent, Patient, Theme, etc., while the second group includes merely two semantic roles – Actor and Undergoer. The roles of the second group are usually referred to as semantic macroroles. Although this categorisation is not universally accepted, nevertheless, it is employed by researchers for a profound investigation of grammar/meaning relations. In the present analysis the classification of Jackendoff (1990) and Dowty (1991) is used. Let’s start from the following examples: Teddy killed the deer with a hunting rifle. A hunting riffle killed a deer. A deer was killed. In the first sentence Teddy performs a semantic role of an Agent, while in grammatical relations Teddy is a Subject. For all that, Teddy is associated with a hunting rifle by means of a grammar/meaning relation of a â€Å"kill† event. In the second sentence a semantic role of a Hunting Riffle is an Instrument, but in grammatical relations it is a Subject. Finally, in the third sentence a Deer appears in a semantic role of a Patient, while in grammatical relations it is again a Subject. Actually, if two participants are involved in an action of a sentence, a grammar/meaning relation is considered to be asymmetric. For instance, in the sentence Jimmy touched Marry two participants are involved in the action, but they perform various roles. Jimmy is a person who starts the action, thus, he is an Agent, while Marry is a person who is influenced by Jimmy’s action and she is a Patient. In this context, an Agent performs a conscious segment of a particular action and a Patient unconsciously responds to this action. As the above example demonstrates, an Agent should necessarily be alive, as it starts an action; however, this attribute is not ascribed to a Patient that is influenced by an action either in a direct or indirect way. There are some English sentences, where only an Agent is presented, such as Steven took a two-week holiday. Although this sentence differs from the previous utterance, both examples belong to a â€Å"do† category. But there are other categories of events, and sometimes it is really difficult to identify the right category (Frawley, 1992). The fact is that English sentences may reflect many similar features, but, despite these similarities, they may reveal various events and different semantic roles. For instance, in the sentence Peter heard a noise, Peter is a participant, but unlike prior examples, Peter does not appear as an Agent, because he is not an initiator of the action, he is an Experiencer. Therefore, such sentences may be attributed to an â€Å"experi ence† category. However, sentences that belong to this category may pose certain problems, as they may demonstrate different peculiarities of events, changing semantic roles in utterances. For example, in the sentence Ann looked at Ted, Ann is an Agent of the action, though she is also an Experiencer (similar to Peter from the previous example). Ann consciously pays heed to something, while Peter is unconscious of his action. Both sentences look similar, but peculiarities of events and semantic roles are different in these utterances. The second complexity that may occur in the process of analysis refers to the second participant of the discussed sentence. While in sentences with a â€Å"do† category the second participant is a Patient, because it is influenced by the Agent’s act, in sentences with an â€Å"experience† category the second participant (e.g. Ted) is not a Patient, as it is not influenced by the Agent’s act. As the above sentence shows , Ted is necessary for better understanding of the event; hence, he may be considered as a Theme of an action. But some utterances in this category have neither an Agent nor a Patient, though at the first sight it is easy to make a mistake. For example, in the sentence Danny loves Mag there are no agents or patients, as Danny does not perform any action and Mag is not explicitly or implicitly influenced by this action (probably she does not even know of Danny’s feelings). In this utterance Danny is an Experiencer, while Mag is a Theme. Unlike semantic roles, grammar roles can be identified more easily; in the discussed sentence Danny is a subject and Mag is an object. In fact, one grammar constituent may have a number of semantic roles; for example, a subject may involve an Experiencer, an Agent, a Patient, while an object may include a Theme, a Patient, an Instrument, etc. Thus, semantic roles provide more accurate and profound information as to the meaning of an utterance than grammar roles; however, both grammar roles and semantic roles are crucial for linguistics. In addition to the mentioned categories, there is also a â€Å"happen† category that is rather facile. For instance, the sentence My car is broken has one participant that is explicitly influenced by an action; that is why this participant (My car) is a Patient (there is no Agent in this utterance). Unlike a â€Å"happen† category, a so called â€Å"information transfer† category may pose certain difficulties for those who analyse semantic roles. In the sentence Jerome informed Timmy of a conference there are two participants – Jerome and Timmy. But while Jerome is an Agent of the occurred event, Timmy is not a Patient, as one may consider, taking into account the previous examples. In this utterance Timmy is a Recipient, and a Patient is absent in this sentence – neither Timmy nor information can be regarded as a Patient, because information is not directly or indirectly influenced by Timmy or by the transfer. In this regard, information in the discussed utterance is a Theme of the event. Overall, in all mentioned examples nouns and adjectives refer or point at a particular event; however, there are also sentences, where these parts of speech pay heed to a specific state instead of an event. Such utterances relate to a â€Å"be† category. For instance, in the sentence Viola is healthy again, Viola is a Participant that also appears as a Theme. In this utterance the state of Viola is determined by the adjective â€Å"healthy†, but not by a verb (as in the prior examples). Therefore, â€Å"healthy† fulfils a predicative role, unlike verbs in preceding sentences that fulfil an attributive role. Sentences in this category may also reflect temporal relations, like in the following utterance: Garry is in front of Nick. In this sentence there are two participants that certainly appear in temporal relations; undoubtedly, if the sentence is changed for Nick is behind Garry, the relations between Nick and Garry will not be altered. In this respect, both participants perform the role of a Theme in the sentence. In view of all observed examples, it is obvious that participants may fulfil either a central role or a marginal role in the action; that is, a division is made between the principal and secondary participants. For instance, in the sentence Nelly embraced Steve before the guests, Nelly is the principal participant, an Agent, while Steve is the secondary participant, an Instrument with the help of which Nelly fulfils the action. Even if an Agent is absent, as in the sentence A stone broke the fence, there is a supposed Agent and an Instrument. Moreover, if two participants are mentioned in a sentence, the secondary participant may perform a role of a Beneficiary, as in the following example: Mommy did homework for Sally. In this utterance Sally is a Beneficiary, as another person (his Mommy) does homework for him. Therefore, the analysed sentences demonstrate that each semantic role may reflect different properties, and identification of these properties may be rather problematic in t he process of analysis, resulting in frequent confusions. Table 2 below epitomises the observed semantic roles, their major functions and possible problems. Table 2. Major semantic roles Semantic role Function Possible confusions / problems Agent The principal participant (always animate) that starts an action An Experiencer may be wrongly regarded as an Agent But: An Agent consciously fulfils an action, while An Experiencer is not consciously involved in the action’s fulfilment Patient The principal participant (either inanimate or animate) that is influenced by an event In certain cases a Patient may perform a role of an Agent This occurs in instances that signify moves; that is, when a participant simultaneously performs an action and is influenced by it Instrument The secondary participant with the help of which an Agent fulfils an action If there are both an Agent and a Causer in a sentence, it may be difficult to rightfully identify instruments of an Agent and a Causer The instrument for a Causer is an Agent An Agent possesses other instruments Theme The principal participant that does not induce an event and is not influenced by it In the case of temporal relations there are usually two themes, instead of one Experiencer The principal participant (always animate) that does not explicitly fulfil an action; instead, it undergoes a certain state (or an event) As an Experiencer is influenced by a state (or an event), it may be confused with a Patient or even with an Agent (when an action coincides with experience) Beneficiary The secondary participant (always animate) that make gains from a certain event A Beneficiary should not be confused with a Patient that is the principal participant Recipient The objective (always animate) of an event that is connected with a transfer A recipient may perform a role of an Agent in such a sentence as â€Å"Father took a strange envelop from Jack† As is shown in Table 2, there are no definite borders among semantic roles; actually, every role may perform different functions in a sentence (Parsons, 1990), and the lack of an integrated structure complicates the analysis. The occurred intricacies can be explained by the fact that any semantic category is based on concepts of subjectivity rather than concepts of objectivity (Knott Sanders, 1998). For example, the word bookcase consists of certain letters and sounds, so it can not be attributed merely to an object. As words and meanings are acquired from a particular social, cultural and linguistic realm (Peregrin, 2003), the relations among all parts of speech are casual, but not natural. Therefore, semantic categories differ not only among members of various societies, but also among people of the same society. For instance, in two utterances Julia prepared bath for Jill and Julia prepared Jill a bath there are certain semantic roles that may be interpreted either as similar or as different. In the first utterance Julia is an Agent and Jill is a Recipient, while in the second utterance

International Development in Developing Countries Essay -- Developing

International Development in Developing Countries â€Å"†¦increasing international trade and financial flows since the Second World War have fostered sustained economic growth over the long term in the world’s high-income states. Some with idle incomes have prospered as well, but low-income economies generally have not made significant gains. The growing world economy has not produced balanced, healthy economic growth in the poorer states. Instead, the cycle of underdevelopment more aptly describes their plight. In the context of weak economies, the negative effects of international trade and foreign investments have been devastating. Issues of trade and currency values preoccupy the economic policies of states with low-income economies even more than those with high incomes because the downturns are far more debilitating.1† The topic that I have selected for my chapter evaluation essay is that of â€Å"Economic Development†. This paragraph above is the best summary of the chapter’s contents. In this chapter the author discusses the influence of development on the three worlds of countries. These worlds are benchmarks set to assess countries economic states relative to each other. When looking through the topic of development, two drastically different ways to assess it arise. The majority of the western world looks at development in terms of per capita GNP. This means each country is evaluated on a level playing field, comparing the production of each country in economic value. Opposite this style of evaluation is that of the alternative view, which measures a country’s development on its ability to fulfill basic material and non-material needs. Cultural ties are strong in this case as most of the population does not produce for wealth but merely survival and tradition. Throughout the chapter the text exerts more emphasis on the economical evaluation of a country's development rather than the alternative method. It begins to branch off quickly into the classification of countries deriving new topics all relating back to the economical approach. Beginning this discussion is the topic of underdevelopment. Many factors can lead to the underdevelopment of a country. The most common sign of underdevelopment is that of a â€Å"Dual Economy†, this takes place when a â€Å"small modern elite and middle class make up about 20-30% of a country’... ...an overabundance of information all applicable to the topic. My feeling was that such an overwhelming load of facts and systems directed me away from the most important facts of the chapter. Its imperative that the student understands the small scale relationship to economic development. Therefore my attempt was to highlight the main topics of the chapter and relate them to the reader to provoke intrest and thought towards many of these important life changing situations that occur everyday. If one can see past all the theories primarily and see the cause and effects behind them, they’re appreciation for the ideas stated in the theories. Bibliography: 1.
