Computers and Education :: Teaching

Computers and EducationComputers in education is such a massive topic. Students ingest been going to classes everyday since they were five years old. How much access did you have to computers in account school? How many of you started to use computer in grade one, two or up to now three? Most of my peers in the same age bracket may not have even touched a computer prior to reaching grade six. Currently students are getting access to computers at a younger age because the availability is becoming to a greater extent sizeable, theyre using them in their classrooms as well as taking classes to learn more information toward computer related subjects. Even though a lot of parents may think that little Johnnie or Susie could only learn Sex Ed from computers and the internet. Lots of parents contemplate the safety of their children when surfing the internet, believing that their kids testament get involved in some of the more damaging effects that they can be introduced over the interne t that they fail to notice the positive of it. victimization the help of a computer and the internet is constructive for students because it allows the students to give a more professional look to their homework, paper and labs. The internet offers students a vast imaging of areas that then can get hold of research and facts about their projects. The computer world is a growing industry. The capabilities of present day machines have grown so rapidly that students have access to numerous programs such as multimedia, internet, education CD and many, many more. Students have the opportunity to learn and to become more dynamic in their school work. Have fun on the computer and learning valuable skill that they will aid them to searching for and getting a crease in this computer operated world. Students are basically learning about computer from three different teaching methods such as correspondence over the internet, in class methods and the good old way of learning on your own a pproach which there is a lot of people out there in the world that has learn vast amounts of knowledge that will get them far in this computer world. Whether, its in the computer business or even another trade. The teaching methods has to chance and become more advance. Teacher have to keep there student active so there not bore. financial support them on their toes.

What is a cultural base? A cultural group refers to state of the same race or nationality who shargon the same values, beliefs, practices, goals and most likely, speak a common language. Members of a certain cultural group undersurface easily identify with each other as if they train a common heritage. Culture can refer to neither social Classes people be involved in nor the lifestyle they live but more importantly culture shows how people are different in many ways. Military, age and righteousness groups are the ones I consider myself a part of. The first group that has been valued by me and many other people is the military. They might not be everybodys favorite group , yet the things they have accomplished for the United States, and many other countries are quite significant. For hundreds of years the United States military members have sacrificed their lives for not only Americas freedom, but also for other countries that have suffered a crisis. The military is currently i nvolved in wars, humanitarian efforts, peacekeeping mission missions and as well as in state sponsored missions and country missions for natural disasters. Military members must be courages due to the risky situations they must endure. For instance, they must be willing to put their life on the line in order to save others. Heroism consists of many characteristics that most military members should have. Soldiers are willing to risk their lives to save their fellow soldiers or serve their country in a war no matter what that cost is. Most of these work force and women fought until they neither won nor got killed during a certain war. Even though many fallen soldiers havent been recognized for the achievements they made, they are still heroes in peoples perspective. I personally... ...lence, yet they dont know that unjustified violence, terrorism and the killing of innocent people are absolutely forbidden in Islam. Islam is a way of living life that is meant to bring peace and equ ality to a society. Therefore people should look deep in the religion and teach it before they judge on it based on peoples actions.

The Horrors of War in Wilfred Owens Poem, Dulce et Decorum Est Essay e

The Horrors of War in Wilfred Owens Poem, Dulce et Decorum Est From the earliest records of history, accounts of war incur been portrayed as valiant acts of heroism. Children and adults alike have gathered in concert to hear tales of war and its glory. From the stories of Alexander the Great to recent-day movies like Saving Private Ryan, war has been praised and exalted with words such as bravery, honor, and freedom. However, Wilfred Owens poetry Dulce et Decorum Est shows the ugly, horrible side of fighting. By use of gripping words and vivid descriptions, Owen paints incredible pictures of what World War I was really like. He snap away the glory and drama and reveals the real essence of fighting fear, torture, and death. No longer are we left with good feelings and pretty phrases like Liberty and arbitrator for all Instead, our hearts grieve over what these sol leavers had to suffer through. Every line of the poem rebuts the Roman poet Horaces quotation Dulce et decorum est pr o patria mori--It is sweet and becoming to die for ones country. The poem employs three different devices that work together to refute the belief that war is heroic and glorious the speakers descriptions, his similes, and his memories.First, the narrators descriptions are clear and effective, leaving no bitterness round what the soldiers had to endure with trenches and table mustard gas. The poem does non use vague descriptions such as It was terrible and horrible. Instead, the fifth and sixth lines read Men marched asleep. umteen had lost their boots / But limped on, blood-shod. All went lame, all blind. Right away, the reader can almost see the weary soldiers heading towards their distant rest. They are so weary that some are sleeping while... ...ys will be a terrible, terrible thing.In conclusion, Dulce et Decorum Est is a magnificent tapestry of poetry. By the speakers descriptions, similes, and memories, Owen weaves reality and memories together to create a masterpiece. Through the speaker, Owen seems to express his grief over those who have died fighting. He sees no glory in men dying horrible deaths from mustard gas, writhing with pain and agony. No, he does not feel that it is sweet or becoming to die for ones country. His opinion is expressed throughout the whole poem. Yet, his poem is not one of beauty. It has no pleasant words or pleasing sounds it does not bring good feelings or happy smiles. But it is one of truth, the truth about war.Works CitedOwen, Wilfred. Dulce Et Docorum Est.

Automobiles Essay -- Essays Papers Cars Driving Environment

Automobiles The invention of the automobile in the early 20th century has had an adverse affect on our environment. Our society has used engine room in order to advance the automobile to make it better and more efficient. The automobile industry knows what sells and they take advantage of that. With this growing technology to advance automobiles alike comes flaws. The biggest and most obvious flaw is pollution. Because of pollution, we find ourselves asking the question of whether this technology has helped our society more than it has hurt it. Automobiles are the cause of 60 percent of our radiate pollution today (Dewees 214). There are four main sources in which pollution comes from an automobile. The first, on a calefactory day the sun will light the gas tank of the car, this in turn causes vapors from the gasoline to leak from the fuel tank. Second, when the car is simply running the engine becomes hot and causes the engine and suck up system to release gasoline vapors. Third, after a car is turned off and parked, gasoline vapors continue to be emitted because the engine is still hot from running. And lastly, when you go to the gas station to refill your gas tank vapors are forced out of the tank into the air. Before we look at more or less alternative process to help reduce or eliminate automobile pollution, we should try to understand how this occurs. This form of pollution is a direct result of the combustion process, too known as exhaust, and from fuel being evaporated into the atmosphere. The next step is to get a better understanding of the combustion process. The gasoline that we use to put into our cars are made of a mixture of hydrocarbons, hydrogen and carbon atoms. When we put the gasoline into our car, what is supposed ... ...s, an alternative solution needs to be made. We need to stop smell at cost efficiency in this matter and decide what is more important, a healthy world to live in or a moth-eaten way to drive. WORKS CITED Alternatively Fueled Vehicles.

The Importance Of Wind Turbines Engineering Essay

With world-wide energy demands invariably on the rise, the demand for sustainable green energy beginnings is vent of all quantify to a greater extent of import. orbicular population growing and emerging developing states p childs played with an exhaustible supply and qualifyless addition in pecuniary entertain of the universe s fossil fuels is doing an increased involvement into alternate energy beginnings. Based on authorizeical ingestion of the universes fossil fuels an appraisal of the space of clip staying before each modesty runs out, taken from World Fossil Fuel Reserves and Projected Dep permition, Colorado River Commission of Nevada, March 2002, butt joint be seen in table 1.Fossil fuelEstimated aging ages left before complete exhaustionPetroleum98 old agesNatural gas166 old agesCoal230 old ages( table 1 )Even though these appraisals do nt take into history the find of new fuel militias and the outgrowth of new more efficient dodo fuel energy engineerings they st ill give a image of why investing and look into into sustainable engineerings is going of all time more extended and popular. solves show that in 2011 the planetary publicise live actor market grew by 20 % with a world-wide investing transcending 50 billion. ( Global Wind Energy Council, 2012 )Wind power engineering is quickly going one of the most popular alternate energy beginnings for several groundsIt is environmentally friendly and get out greatly adulterate down C dioxide emanationsContrary to popular belief, connoteder turbines be going more and more efficient at change overing energy and hence more cost effectualWind power unlike fossil fuels is an unlimited beginning of energy and is readily obtainable all around the universe.Low running costs one time wind turbines put up been set up and a comparatively little necessary work force compared with conventional energy engineerings.Much safer than dodo fuel combustion and atomic power workssHistory of origin ele ctric current turbinesWorlds have been tackling the power of the air current for 1000s of old ages. The earliest hint bathroom be dated as far back as 4000BC where the ancient Chinese began utilizing the air current to power canvass attached to their ships. Other than sailing, the air current has tranced much technological promotion. It has played an of import function in agribusiness, where windmills have been utilise to squelch grains and irrigate Fieldss.It was nt until the last 150 old ages that wind power has been used to change over kinetic energy into electricity. The first of all time mechanically ope treadd air current turbine in the universe was built in 1888 by Charles Brush. It consisted of receipts leaf brand names and was able to bring forth 12 KW of power used to bear down batteries. ( wind power coevals ) . But it was nt until ww1 and ww2 where air current turbines were used commercially as a beginning of energy ( strangely in Denmark as it was cut off from oil supplies from the remainder of Europe.After this period research and involvement in air current engineering was non preserve due to the belief that it was non cost effectual. Although there was small planetary involvement in air current engineering at this clip some research was still carried out by independent developers, most notably the design of the 200KW Gedser air current turbine in Denmark. This was a pioneering design consisting of three truehearted makes and flying tip interruptions and is mostly considered be the trademark of all modern twenty-four hours wind turbines.It was nt until the 1972 oil crisis that wind power began to come into fruition with Denmark and the USA pickings the manner in invention.Gedser air current turbine Denmark( hypertext transfer protocol //www.energimuseet.dk/ )Modern twenty-four hours wind turbinesModern twenty-four hours wind turbines differ greatly from Charles Brush s 144 leaf blade turbine both in aesthetics and public presentation , but the rule behind bring forthing electricity is the same. Aerodynamic lift forces caused by the air current blowing past the blades cause them to revolve a shaft and in bend power a generator which converts this mechanical power into electricity.CategorizationThe air current turbines can be split into two classsHAWT horizontal axis air current turbines, these are turbines which axis of whirligig motion are horizontal, and VAWTS perpendicular axis air current turbines, these are turbines which axis of rotary motion are perpendicular.There are advantages for utilizing either for case the VAWT in non wind sort orientated and does non aim to reside the way of the air current whilst HAWTS do, but HAWT s are much more economical and practical than VAWT s and besides produce more power. HAWT s are by far the most common constellation of air current turbine and therefore for the intent of this thesis merely HAWT will be discussed.Example of a typical HAWT Example of a typical VAWT ( hypertext transfer protocol //www.turbinesinfo.com/ ) ( hypertext transfer protocol //www.top-alternative-energy-sources.com/ )When planing a HAWT there are several factors which have to be taken into historyThe HAWT design can be split into four different subsystemsTurbine rotor subsystemPower-train subsystemNacelle subsystemTower subsystemTurbine rotor subsystemThe design of the rotor subsystem if oft considered the most of import, as it straight affects the cost, efficiency and public presentation of the air current turbine. When planing a rotor subsystems there are several facets which must be examinedShape of rotorFrom flying tip to root, the form of the rotor blade does non stay changeless. The tip of the blade is much narrower than the root. This is because of demand for the root to structurally back up the remainder of the rotor blade. Besides the farther off from the root the greater the additive fastness, purchase and the greater the part toward the blades rotation.Po wer= force ten velocity This mean that points nearer the shaft have less of an consequence on rotary motion, and hence time laging a thicker less aerodynamically efficient blade sleeve at this point will non hold every(prenominal) composition serious effects as it would at the tip.Unlike a typical aeroplane flying blade a air current turbine blade has a just sum of turn. Besides unlike an aeroplane wing, turbine blades undergo rotational motion doing this demand for greater turn. Turn of a turbine blade is when the tip is non parallel to the root. As mentioned before the tips of the blade have a greater additive velocity than closer towards the root, but the air current velocity along the full blade remains changeless. Due to the comparative velocity non staying changeless along the blade, holding the same slant of onslaught throughout would intend different points along the blade meeting the air current at sub-optimum angles of onslaught with hapless lift to drag coefficients. accordingly to do the angle of onslaught relation to the way of wind the same throughout the full blade, a turn angle must be implemented. ( wind turbine engineering, pg 53 )Number of bladesModern twenty-four hours HAWT most normally have merely two or three blades, although they would still work with a smaller or larger embark of blades, but these constellations are uncommon. It is mostly considered that three blade turbines are the most effectual with the best combination of balance, efficiency, and aesthetics.Blade pitchBlade pitch is the angle between the blade chord line and the plane of rotary motion. Pitch mechanisms allows for a manner to command the starting torsion, peak power, and halting torsion of the turbine ( Wind turbine engineering, pg 51 ) . to the highest degree big air current turbines have a pitch mechanism integrated into the design, but due to their cost some smaller turbines have heady pitch. Some wind turbines may besides hold tip interruptions. These halt the rotor rotary motion by turning the tip of the blades to right angles with the way of gesture, doing an addition in retarding force.Blade MaterialChoosing the right stuff for the design is of import, depending on the rotors size and design a stuff with equal strength, stiffness, weight and cost must be found.Early on air current turbine rotor blade designs consisted of wooden complexs and lightweight metals. Most wind turbines today use either fiberglass or plastic complexs for building due to their low costs, strength and weariness features. ( wind power, Paul gipe, pg 110 )Power train subsystemConsists of a series of mechanical and electrical constituents, to change over mechanical power caused from the rotor to electrical power. It includes low velocity and high velocity thrust shafts, a gear box, an electrical generator and a rotor brake every chip good as subsidiary equipment. ( wind turbine engineering, pg 52 ) . This is done by reassigning mechanical energy from the low velocity thrust shaft attached to the rotor, to a high velocity thrust shaft to power a generator.Nacelle subsystemThe nacelle is the lodging to all of the power train subsystems every bit good as the gaping systems. It must protect these systems from all conditions conditions every bit good as act a primary perfume way from the shaft to the tower. ( wind turbine engineering, pg 54 ) .The ability for a turbine to gape is of import. A turbine turned at 90 & A deg to the air current will bring forth no lift and hence no rotary motion, whilst if it is at 0 & A deg to the air current it will bring forth maximal sum of lift and maximal rotary motion. Yawing is of import in acquiring maximal power out of a air current turbine and horizontal gaping a twosome of grades to confront the air current will profit.Modern air current turbines have a yawing mechanism to let, non merely for the turbine to confront the air current but when in non in opeproportionn to confront 90 & A deg to the air current to halt rotary motion. ( wind turbine engineering, pg 54 )Tower subsystemThe tower raises the nacelle and the rotor off the land. The tallness of the tower is dependent on geographical location and the trade of between increasing the tower tallness to give away more powerful air currents and cost. The tower must be structurally really strong and stiff both to back up the nacelle and rotor, every bit good as withstand quivers caused by the rotor. Towers are normally made from steel or reinforced concrete. ( wind turbine engineering, pg 56 )Tip velocity proportionThe velocity in which the blades rotate is an of import factor to see. If the blades rotate excessively easy so most of the air current will go through between them tranquil with really small energy extracted. If excessively fast, so the blades will be whirling through disruptive air caused by the other blades, every bit good as doing the turbine to be put under increased emphasis which could take to mech anical failure. Wind turbine blades are hence designed to revolve with an optimal tip velocity ratio to gain out the maximal energy possible from the air current.Tip velocity ratio can be delineate as the ratio of blade tip velocity to weave velocity.The tip velocity ratio is straight affected by the figure of blades of a turbine, the few the figure of blades the faster the rotary motion velocity will necessitate to be to pull out maximal power. For three bladed air current turbines the tip velocity ratio is by and large in the scope of 6-8 with 7 being the most common value ITECHOPEN.com pg Betz one pg 29 slackly interior decorators will take to maintain the tip velocity ratio every bit high as possible to increase the velocity in which the shaft connected to the generator spins, but higher tip velocity ratios besides have several disadvantagesIncreased tip losingss ensuing in fall efficiencyIncreased noiseIncreased quiverErosion caused by dust atomsEfficient airfoil design i s hence particularly of import to let for higher optimal ratios to be met whilst restricting these negative effects.Finish Lift, Drag and Pitching MomentThe lift, retarding force and pitching minute are all moving on a air current turbine rotor blade. And figure . shows the orientation of these. Lift is the force moving perpendicular to the oncoming air flow and is undeniable to get the break out of gravitation. ( Hansen,2008 pg 8 )The retarding force force acts perpendicular to the lift force and hence parallel to the oncoming air flow. The retarding force force is a combination of the cloying forces between the air and the airfoil, and the force per unit area differences over the airfoil ensuing in whirls.As mentioned by Hansen, 2008 pg 8 the lift to drag ratio should be maximised to acquire a more efficient airfoil. The coefficients of lift and retarding force can be defined asWhere, is the air denseness and is the length of the airfoil chord. These coefficients are maps of Reynolds figure, Mach figure and angle of onslaught.To to the full depict the forces it is necessary to cognize the pitching minute about a point of the airfoil. As stated by Hansen 2008, pg 8 This is located at a distance of ? length along the chord line from the taking border. It is defined asBetz boundThe Betz bound was foremost introduced by German applied scientist Albert Betz in 1919 and is the maximal supposed power that can be extracted from a air current watercourse. Harmonizing to Intechopen.com pg 26 for maximal energy stemma the downriver speed should be equal to of the upstream speed, therefore the optimal value for the power coefficient will goThis value is about and is known as the Betz bound. Using this standard a value for air current turbine efficiency can be defined as the ratio of power coefficient to Betz boundFigure Hansen 2008 pg 40 shows how the maximal efficiency is affected by the tip velocity ratio. For low tip velocity ratios the efficiency will be decreased for illustration, a tip velocity ratio of 1 will give a maximal efficiency of about 70 % , whilst a tip velocity ratio of 10 will give a maximal efficiency of about 98 % . This shows that air current turbines higher tip speed ratios can pull out more energy and therefore a higher tip velocity ratio is a coveted feature.Blade Element Momentum theoryBlade persona passion theory is a combination of two air current turbine analysis methods. The 1st method is to execute impulse balance equations on a revolving ringed watercourse tubing which passes through the turbine. The 2nd is to analyze the forces generated by the lift and retarding force coefficients along the blade by dividing it into subdivisions.Momentum theoryAxial forceAssuming a air current turbine as being in a control volume disc actuator theoretical account as seen in figure PremisesThis is a really basic theoretical account which assumes no aftermath rotary motion.Stations 1, 2, 3 and 4 are at lines upriver of the turbine, merely before the turbine, merely after the turbine and downstream of the turbine, severally.Between Stationss 2 and 3 energy is extracted from the air current ensuing in a force per unit area alteration. The mass flow rate of the control volume must stay changeless harmonizing to the continuity equationBesides if we assume continuity of speed through the turbine so and and because the flow is frictionless so we can use Bernoulli s equation between 1and 2, every bit good as 3 and 4 giving up junction these equations givesAs force is equal to coerce clip s country so the push generated by the turbine can be calculated asThe axial initiation factor is a factor of vaiation of the cross sectional country of the turbine blade which varies as a map of flow speed. ( Eng.fiu.edu, pg 21 ) . It can be defined asThereforeIf this is substituted into the trust equation it yieldsUsing this equation the power end product of the turbine can so be found by specifying it as thrust times speed. ThereforePower and Thrust CoefficientThe power generated by the kinetic energy of the air current fluxing at a air current turbine can be defined asThe public presentation parametric quantities of a air current turbine can be characterised by the power and thrust coefficients. Where the coefficient of power is the ratio of power generated by the air current turbine to power available given bySimilarly the thrust coefficient can be defined asHarmonizing to the Betz limit the coefficient of power can neer transcend a value of. These public presentation parametric quantities can be link to the axial initiation factor by uniting with the power and thrust equations severally givingBlade Element TheoryBlade component theory involves dividing a blade up into N figure of subdivisions ( or elements ) . The fluid flow will be different across each component as they will hold different rotational velocities, chord length, and turn angle ( wind turbine design grant ingram ) . Therefore numerical integrating along the blade span is required to find the overall public presentation.Relative speedThe comparative air current speed is the vector amount of the horizontal air current speed at the blade, and the speed caused by blade rotary motion. The rotary motion constituent is the vector amount of the blade speed and the rotational flow due aftermath rotary motion is.To give a more accurate estimation of the airfoil public presentation an norm of recess ( place 2 ) and issue ( place 3 ) is used where is the mean rotational flow due to wake rotary motion. Wind turbine explained pg 107. Knowing this an equation can be writ for the mean digressive speedFigure 5 shows the geometry of a air current turbine blade grant ingram pg 9From the figure 5 we can infer thatWhere the value of will change along the span of the blade. This equation can be related to the tip velocity ratio which is defined asThreforeUsing figure 6 we can besides associate that the equation f or the comparative speed isBlade ElementssFrom figure 6 the forces moving on a blade component can be seen. These forces can be equated asTaking into history the coefficients of lift and retarding force antecedently defined as equations .. ClCd graph possibly? ? ? ? ? ? ? ? ? ? so the forces moving on a blade component can be written asWhere B is the figure of rotor blades. The torsion moving on a subdivision of the blade is the digressive force moving at a distance R from the Centre and is given byFrom this equation the influence of retarding force can be clearly be seen. An addition in retarding force will diminish the torsion hence the power end product of the turbine. This is why when selecting or planing an airfoil for turbine usage, one of the key aims is to maintain the coefficient of retarding force every bit low as possible while keeping a high coefficient of lift.These equations can be expressed in footings of initiation factors by replacing equations and si mplified by utilizing the solidness factor. The solidness factor can be defined as the ratio of blade country to country of the disc given by the equation The equations can so be written asThese two equations specify the push and torsion moving on an annulate subdivision of the blades severally.Tip losingssDue to the difference in force per unit area on the top and underside of the airfoil, air flows from the high force per unit area side to the low force per unit area side around the blade tip, cut downing the lift of the blade. To account for this loss of lift and hence power, a chastisement factor is implemented. A method of gauging the tip losingss was obtained by L. Prandtl and the equation for the rectification factor isWhere is in radians. Equations.7,17 so goBlade component impulse theoryEquations for blade component impulse theory which are used in blade design and optimisation can now be defined by uniting the impulse theory equations for axial push and torsion, with b lade component forces equations. These areUsed for ciphering initiation factorsPower end productThe entire power of each ring can be calculated utilizing equationThe entire power from the rotor can be calculated utilizing the equationWhere is the hub radius. The power coefficient of the rotor can now be calculated utilizing the equationWhere is the blade tip radius. Using the annulate subdivision torsion equation this power coefficient can be written as

Gang violence Essay

Once found princip eachy in large cities, violent street gangs now affect public safety, community image, and quality of life in communities of all sizes in urban, suburban, and rural areas. No region of the United States is untouched by gangs. Gangs affect society at all levels, causing heightened fears for safety, violence, and economic cost (In The bring out) As the quote above shows, gangs and everything that goes with them has spread all over the United States and is now star of the major issues the U.S. faces. There are estimated to be about twenty-nine thousand, four hundred gangs and s rase hundred fifty six thousand gang members all throughout the U.S. Also, there are thousands of other gang members illegitimately crossing the U.S. borders, close toly from key the States. Each gang differs in some way but however, A common definition for a gang is a group of three or a lot individuals who engage in criminal activity and identify themselves with a common sign or name (Barbour 9). The main problem in the U.S. is not the actual gangs, but it is the drugs that they involve themselves with.The drugs only bring violence and problems. The main purpose of many gangs today is not to happen turf or power but to get money by import drugs over the borders and then selling them. Gang activity and violence is occurring all over the U.S. every day, mainly behaved by the interestingness of illegal narcotics, if this country wants to stop the gangs, it needs to completely swing off the smuggling and trafficking of drugs from cardinal America into the U.S. by combining diametrical government agencies of different levels to pr nonethe slightt the gangs from entering the U.S. and growing and also to create prevention programs and groups to control it at a to a greater extent(prenominal) localized level where the issues are the most pressing.Gangs are smuggling over the U.S. borders and it is causing more problems than the government can handle. The main s ource of drugs is coming from Central America, where the most predominant number of gangs is located. Many gangs are focused only on smuggling different types of drugs into the U.S. and it is the one way to sustain a immutable source of income. This is very appealing to any youth who wants money and that is why the number of gang members is growing so rapidly. The transnational gangs are located in over 300 cities and 40 states across the country and are becoming a seriousthreat to the national security of the United States (Farah). Mara Salvatrucha (MS-13) is the most dangerous gang in the U.S. today and is not even native to the U.S. The homeland of MS-13 is in El Salvador. El Salvador is the most highly gang live country in Central America. Some other gang-infested countries are Guatemala and Honduras. There are about ten thousand MS-13 members in the U.S. alone and about forty thousand members in Central America. Unfortunately, these numbers are still on the rise. MS-13 recrui ts members at a very young age, which keeps a steady growth in members. The idea of a better family and brotherhood, but also money, is very appealing to any kid who is struggling at home. MS-13 accounts for the majority of drug distribution from Central America and is the focal point that needs to be attended to if this problem is going to be solved.Another main problem with the drugs is how large of an impact they confound on the people because they only add to the already existing problems for society. Also, violence and drugs go hand in hand, which is why they are so involved at bottom the gangs. Violence is always involved with gangs, but with the addition of drugs, the violence can intensify to a level where nothing can be through. This causes the gangs to be overmuch harder to deal with. One main problem is that the American society hates the gangs but loves the drugs and leave continue to buy drugs no matter where they are coming from. This makes it even more difficult t o deal with. The drugs find a way to enter the lives of people from all of American society. For instance, they have been involved in different businesses and been the cause of murders, including celebrities. Gangs have a large familiarity in the rap industry and are related to the murders of Tupac Shakkur and Biggie Smalls (Smith, Gangs). Tupac Shakkur and Biggie Smalls were two iconic rappers of their term but sadly, gangs found a way into their lives and ended up causing both of their deaths. The drugs and violence become so intertwined into society, that now they are very hard to remove and a settlement to this problem needs to be found.There are many different processes that are be implemented now to stop this problem. An example is that groups and programs are being organize to fight back against the gangs. The azimuth Corridor has proven to be one ofthe busiest places for gang smuggling and trafficking. There was a group formed to prevent it called IIMPACT Arizona. IIMP ACT Arizona is a multi-agency project that is managed by the Gang and Immigration Intelligence Team Enforcement Mission (GIITEM) and designed to address rising crime associated with illegal immigration. (Gang and Immigration Enforcement) IIMPACT is acronym that stands for black-market Immigration Prevention and Apprehension Co-op Teams (Gang and Immigration Enforcement). IIMPACT is a program where local, state and federal official practice of law forces team up to fight against smuggling make by crime groups. The main goals of the group are to deter, disrupt and dismantle gangs from illegally immigrated people and drugs into the U.S. If they are able to succeed with what they want to do, then they would be shutting drink one of the hotspots for gang smuggling. This group is in action today and could eventually make a large impact on preventing gangs from smuggling over the U.S. borders, which would greatly decrease the amount of drugs that would be entering the U.S.The U.S. gove rnment has tried to pass different acts and laws against gangs but there has been many legal issues revolving near the civil liberties of the individuals being persecuted. Responding to the rise in gang violence in the early 1980s, Los Angeles judges began to issue gang injunctions. This occurs when the city attorneys way issues a restraining order against specific gang members. This is done only after gathering evidence from police officials and the public. However, in 1987, the American Civil Liberties Union (ACLU) challenged the injunctions, indicating that they presented a violation of an individuals civil rights (Smith, Gangs Outlook). Whenever the government gets close to cracking down on the gangs, an issue involving civil liberties arises and prevents the laws to be passed. The way some of the laws enabled police officers to treat gang members and the hostile level violated some of their rights. In 1994, the Violent Crime Control and Enforcement Act of 1994 was passed and it tightened the choke hold on gangs. It stiffened the penalties for crimes pull by gangs, so that the members would be less prone to break the law. The penalties for a gang member were much more severe than one for just an median(a) person, even if the same crime was committed by both of them. Many lawmakers and law enforcers believe the answer is to make laws tocombat the actions gangs. If the penalties are stiffened, then they allow for be less prone to smuggle drugs and the drugs levels will go down. If drug trafficking can not be stopped, then there is no chance of lag down gangs and the violence they create.The solution to this problem will take time and effort but will work. More groups and programs have to be made in order to stop the drug smuggling and gang violence. Also, younger kids have to be reached out to early on so they dont even have the option to join some sort of gang. If more localized programs can be formed, then smuggling can be cut down from area to area and over time, will disappear. Even though there was extensive research, only one program that was focusing on gang involvement in their area was found and it had been working efficiently so far (IIMPACT). This group is so successful because it requires the usage of town police, state police and federal police all working together. The information that can be shared from each level is key to success. A joint effort is always more successful than a singular effort. If different levels of government enforcement could join up and work together in states all along the border, the smuggling of drugs could be cut down immediately. The combination of different agencies has brought up results that show that gang violence and just gangs in general are able to be controlled if not reduced a significant amount (In The Spotlight). This combination occurring much more frequently can be the resolution to the problem that has needed to be solved for so long.The main problem can be seen lying withi n the gangs but the actual problem revolves around the American educational institutions and the environments that kids are provided with. The American Civil Liberties Union (ACLU) believes that laws will not help and that providing the right environment for kids is what is needed. The main problem with setting a lot of laws and enforcing them is that even if a kid is stopped from being fully involved in a street gang by sending him to prison, he will be more likely to join a gang in prison than out in the world because of how frequent prison gangs are. By trying to prevent one problem, the laws would only cause another. If younger kids were provided with better opportunities to enact in a community and have a better environment to conduct their actions, they willbe less prone to join gangs (Smith Gangs Outlooks). Groups like the ACLU are trying to stop the problem before it arises and that really is the best possible thing that can be done in this situation. If the number of gang m embers goes down, then gangs will lose their power and influence over the surrounding communities. This would cause there to be less drug smuggling occurring and the problem would gradually decline to a non-existing issue.Gang activity and violence is occurring all over the U.S. every day, mainly caused by the involvement of illegal narcotics. If this country wants to stop the gangs, it needs to completely cut off the smuggling and trafficking of drugs from Central America into the U.S. by combining different government agencies of different levels to prevent the gangs from entering the U.S. and growing and also to create programs and groups to prevent it at a more localized level where the issues are the most urgent. The information that was presented shows how much damage that the gangs are causing to the U.S. and how drugs being smuggled over the borders from Central America are the main cause. This is very important because some of what is being done now and what can be done cou ld be the solution to this enormous problem. Possible trends in the future will definitely be that more laws and acts will be proposed and whether or not they go into action, they will make a positive affect on trying to stop gangs in the U.S. Gangs were first formed in the U.S. in New York in the early 20th century, particularly 1928, so it could be the first time in one hundred geezerhood where gangs are not relevant in the U.S. Also, it could make a large global impact because it would encourage other nations to crack down on gangs too. If the prerequisite steps are taken, the problem of gangs in the U.S. could be completely ended and we could experience a gang-free and drug-free time period in the U.S. for the first time in years.Work CitedBarbour, Scott, ed.

American Success in Achieving Independence Essay

IntroductionThe British military was take aimed the strongest in the world at the out arrival of combat between England and the the Statesn colonies in 1775. Britain had just defeated France and the Indians in the Seven Years War and had attained its prominence as a worlds superpower. Yet despite Britains overpowering military dominance, the British found themselves futile to subdue widely distributed cap and the American colonies. The Americans victor in achieving independence during the American Revolution was not due to General Washingtons strategical skill but by numerous British blunders. The British mistakes during the Revolutionary war are they never had an overall outline they failed to identify the Center of Gravity, shifting from offensive strategy to a defensive strategy and diverting the war to the entropyern colonies.Overall strategyThe British never had an overall strategy for winning the Revolutionary War. They acted vigilantly at points when authoritative an d overserious attacks could lease undermined the Continental soldiery. The British assumed that American rebellion would disintegrate when British troops lands on American shores. They believed that the Continental Army was amateurish and unable to fight a interminable war against an organized British military force. Not until after the Battle of Bunker did the British even begin to consider in terms of war rather than simply rebellion. Britain certainly not intend for a lengthy war and constantly expected for the one pivotal victory. The Continental Army was fighting a domestic war while the British had to ship their troops from across the Atlantic. Fighting against their own countrymen was in any case two a psychological and emotional handicap for the British soldiers.The British military regularly made mistakes, especially General Howe. His indolence to take action at the start of the war made it probable for General Washington and the Continental Army to survive. Occurrenc es of poor communication and collaboration between British commanders resulted in cadaverous occasions as well in Saratoga and Yorktown. The component of period unceasingly handicapped British maneuvers. Communications both across the Atlantic and in spite of appearance the colonies were dawdling and useless. Some commanders took matters into their own hands and followed strategies that they felt best suited their immediate goals. The indecision surrounding responses frequently led to unwarranted caution, unnecessary delays, or unforeseeable prospects in strategic situations, which eventually demonstrated to be costly. Because of the length of time it took for communications, field conditions continually changed.Failure to identify the Center of GravityThe Americans had no discernable central government and the British could not determine a truly decisive Center of the Gravity (COG). The COG is the hub of all power and movement, on which everything depends (Clausewitz, pp. 595-596 ). There was no COG that Britain could seize and end the war. There was no one that the British military could defeat that would quickly bring about the giving up of the entire colonist opposition. Throughout the campaign, General Howe continued to allow the Continental Army to withdraw from the field without entirely destroying them. General Howes unwillingness to express a forceful pursuit and destroy General Washingtons Continental Army saved the Americans from a defeat that could have possibly ended the American Revolution. General Howe did not take into account that the Continental Army was the life of the rebellion and should have been considered as the COG.The British dissipated an opportunity to chitchat a destructive defeat on the Continental army at the Battle of Bunker Hill in June 1775. Although they strained the insurgents from the elevated field, the British army missed their chance to deal the rebellion a possibly disastrous blow from the start. Another chance of de struction of the Continental Army came in expansive 1776. General Washington and the Continental Army had been routed in the Battle of Long Island and withdrew to the defenses of Brooklyn Heights, which left them confined between Hessian and British troops and the East River. General Washington was able to keep the revolution alive by maintaining the Continental Army in the field.Shifting from offensive strategy to a defensive strategyWithout French assistance, it is uncertain that the American colonies could have been a match over Britains sizeable and well-equipped military. France clandestinely provided the American colonies with supplies and money, and upon formally declaring war on England in June 1778, also committed soldiers and naval fleets. With the French joining the naval war, Britain switched from an offensive strategy to a defensive strategy since their naval A-oneity is contested. Operations in America became secondary to defense of the British Isles and handsomer e conomic interests in the Caribbean.The ministry decided to defend and strike the French in West Indies, which was regarded as more worth(predicate) than the American colonies. The British militaries had to be dispersed in several theaters and spread so thin across the Atlantic and no longer concentrated on the colonies, which consequently lost the war in America (Middlekauff, p. 438). Britains failure to identify key locations to concentrate her Navy led to not able to unspoilt their nearly strategically located territories and did not have enough military resources to continue the war in America. With the defense thus concentrated, Englands great weapon, the Navy, should have been vigorously used on the offensive (Mahan, p. 394).Diverting the war to the southern coloniesDuring the initial years of the American Revolutionary War, the initial military battles were in the north. The British changed their strategy to focus on the southern colonies as the leadership felt that the sou th was home to many loyalists where they could enlist their support and assistance. England felt loyalists in the South were oppressed by the revolutionary government and would flock to them in support (Mahan, p. 516). Britain constantly pursued and hoped for Loyalist support but was never received.Moreover, Britain also decidedly did not do what was needed to gain and sustain the Loyalists support because they inclined to disregard the help that the Loyalists contributed. In addition, the British Parliament assumed that loyalists would be a more intimidating force and play a more effective position in the war. The British was successful in most conventional battles fought in that region, but American generals in the south turned to irregular and hit-and-run combat that ultimately thwarted the British military. The British should have focused most of their forces on the Continental Army in the north instead of taking the south.Counter-ArgumentSome argue American independence might not have win without the leadership of General George Washington. He was honest, brave, and sure that the America and its Continental Army can win. He certainly not gave up faith that he would reach that object. His first military victory resulted in the British evacuating Boston in March 1776. General Washington reevaluated the wisdom of the tactical defensive and thereafter avoided confrontations with large concentrations of enemy forces after unsuccessful defense of New York and next Philadelphia. General Washington came to realization that it was far more critical for him to maintain the army as an entity than it was to win any particular battle or campaign (Weigley, p.12).Instead of trying to defeat the British in one decisive action, General Washington instinctively realized that the revolution would survive as long as the Continental army survived. Washington had to remain not only on the strategic defensive, but frequently on the tactical defensive, as well. He correctly un derstood that, by keeping his army intact, he could keep the revolution alive. If he could maintain the war long enough, Britain would exhaust her resources and struggle across the Atlantic and independence would be gained. Although General Washington lacked major victories in the Revolutionary war, his historied two tactical successes, at Trenton and Princeton, were conducted against smaller concentrations of an enemy force. But, General Washington made a number of excellent decisions at crucial generation throughout the conflict.ConclusionBritain had an enormous military advantage at the beginning of the American Revolution with vastly superior naval power and a sea captain military with far greater financial resources. The British fought a much weaker enemy yet failed to accomplish its military and political objectives. General Washington recognized that the Continental Army was the backbone of the revolution, the Center of Gravity, where the British failed to identify. Anothe r reason was the assistance the Americans received from the French. The British military were remarkably unmatched and clearly the superior army, and had the French not provided aid, it seems unlikely that General Washington and the Continental Army could have defeated the British. They pulled together and were able to capitalize on the Britishs blunders.Bibliography1. Clausewitz, C. On War. Michael Howard and Peter Paret, eds. and trans.

Analysis of a Hearing Loss

SHS 150 November 26, 2012 Analysis of Experiences/Expressions of H atrial auricleing Loss About 37 million raft, in America, are affected by a earreach spill of some kind (Hearing loss, 2011). Only about 15 percent of those affected actually bump treated for their listening loss, no matter how mild or s forevere (Brody, 2012). This means people are either in denial about the hearing loss or are non aware that they have one. In order to properly analyze the experience of having a hearing loss, I wore earplugs for 8 hours in activities I would do on a normal basis.Some of these activities include attending class, doing homework, shopping, eating at a restaurant, watching TV, and hanging out with my roommates. corrosion the earplugs simulated me having conductive hearing loss, a type of hearing loss in which sounds is not puff up conducted from the ear canal to the eardrum and middle ear bones (Conductive hearing loss, 2011). The degree of hearing loss simulated is mild, which m eans that speech understanding is reduced, especially in noisy environments (Hearing loss, 2011). This experience gave me a curt insight on how peoples lives can become more than complicated by having a hearing loss.In my first activity with the earplugs in, I tended to(p) one of my regularly schedule classes. This class is in a decent sized lecture hall, where the professor was standing at least 50 feet past from where I was sitting. Normally in this class I would listen to the professor speak as I wrote down notes in my notebook. Because the earplugs hindered my listening ability, I was labored to stare at the professor throughout the class to even remotely hear what he was saying. I began trying to read his lips to help understand more of what he was saying, solely when I did this I was not retaining the information he was saying out out loud.I became very frustrated very quickly and realized I had not actually learned much in this lecture. Next, I attempted to complete so me homework back at my apartment. It was a little easier to slenderize on my work because the sounds of my roommates talking or music being played where not there to distract me, like they usually do. While doing my homework, one surface did arise because I was so concentrated on reading, things I could have heard even with the simulated hearing loss were non-existent.My roommate came to ask me a question and ended up startling me because I did not hear her walk up before she touched my shoulder. She told me she had already started talking to me and that I was not responding at all. While shopping for groceries and at the mall, I had a whole other(a) set of problems. At the grocery store, I could not tell when other shoppers where waiting behind me to pick an item I was standing by. This became frustrating for not only me but also the other shoppers.Later, I asked a prole where a specific item was located and could tell by the look on their face that I was speaking too loud. Wh en he answered my question I had to ask them to repeat the last part of their sentence again because another customer was talking on their cell phone right next to us and the workers words became very distorted. The grocery store, as a whole, was a very noisy place so I heard a lot sounds but a lot of times all the sounds became jumbled. The mall was a very similar situation, except that I know my way or so very well so I did not have to ask for help.However, I normally would have asked the workers at certain stores if they had any deals or if specific items came in a different size, but I refrained because I was already aggravated from the other activities of the day. When the greeters at the store entrances said something, I usually just smiled and kept move unless I could clearly hear what they said. I am sure it was an awkward encounter for them if I did not say anything back but I did not want to hear them wrong and say something wrong and embarrass myself. Needless to say, I left the mall empty handed.Two activities that proved to be less rag than I originally thought they would be was watching TV and hanging out with my friends. I turned the TV volume up, which helped me hear it somewhat better. Also, I was mostly watching a football game so I could see how that could be less challenging than a sitcom because even if I could not hear every word the announcers were saying I still knew what was deprivation on if the game. The last major event I wore the earplugs too was going out to eat with my family. This proved difficult since there was music playing and a lot of other groups talking throughout the restaurant.When ordering I had to really concentrate on what the waiter was saying so I did not have to ask him to repeat himself. I did a pretty good origin but I was a little slower reacting to some of his questions than normal, as it took longer to process what he was saying. Once the 8 hours of wearing the earplugs was up I was very relieved to take them out. Conductive hearing loss can be caused by numerous things, mostly commonly an ear infection, impacted earwax, a damaged ear drum, and poor Eustachian tube performance (Conductive hearing loss, 2011).As mentioned before, almost 85 percent of people with a hearing loss choose not to get treated by a doctor. Hearing loss awareness is not as high as it should be in America. Most people believe losing hearing is just a part of getting older, but some other reasons could be affecting their hearing and could eventually be reversible. In certain cases, the cause of a hearing loss could be a tumor, which if not treated could be deadly (Hearing loss, 2011).With the use of iPods and other listening devices increase in kids and teens, their risk of obtaining a hearing loss is also increasing. They are most likely not aware how listening to their music too loud can affect their hearing. More awareness needs to be brought to this subject as well as other similar situations. Even if a pe rsons hearing loss is something that can be fixed with a hearing aid, it is important to get one because activities such as driving, walking across a street, and working in certain environments could be dangerous, if you cannot hear properly (Brody, 2012).Through this experience, I have had a small taste of how a hearing loss can sincerely affect my everyday activities. It was a very lonely and sometimes depressing situation because simple communication was a labored tasked. I am normally very big on multi-tasking, but in certain cases the simulated hearing loss hindered my ability to do other things as I tried to listen to someone speak. The best word I can find to sum up how the whole experience affected me is I felt disconnected.The cudgel part about this disability is it is a hidden one. Other than some people wearing hearing aids, a person with a hearing loss is not always identifiable and therefore much harder to distinguish if they need assistance with something just by l ooking. From this experience, I have decided if I ever develop a hearing loss, I will visit a audiologist right away to figure out the problem for my safety and the safety of everyone around me.

World Wrestling Entertainment

WWE, Inc. The WWE is not just the biggest wrestling familiarity in the United States, nevertheless it is as well as the biggest in the world. The company has gone about this by spreading the WWE name and logo tot eachy over the world through international expansion. The expansion of the WWE product into abroad market was more of a necessity considering the current situation of the wrestling industry in the United States. Linda McMahon, CEO of adult male grapple Entertainment, Inc. out downsloped her think behind the push to expand globally in a press gathering held on August 23, 2004.The main reason being an increased call for for the WWE product abroad, as wellspring as impressive attendance numbers when events were held internationally. Additionally, attendance at reside events or house shows, were very low. Linda McMahon said that by providing more shows overseas to fans that normally do not attain the chance to see the WWE live, they get out be satisfying a need as well as covering for a declining market in the United States (wwecorporate. com 2011). Due to the increase in live events overseas, the WWE also hired more international cater members in order to handle and continue the expansion.Another aspect that helped the WWE expansion internationally is their television presence in many countries. On their corporate website, the WWE lists thirteen countries in which they maintain television deals. Included are the United Kingdom, Japan, France, Mexico, and others. Obviously, this is important because their push to increase live events overseas would not be successful if they did not have television deals in place. Otherwise, the tidy sum in these international markets would have no clue as to who the wrestlers are and no reason to emergency to pay notes to see them live or purchase WWE products.The WWE also has licensing agreements with about 75 licensees worldwide. The licenses use the WWE logo and its trademarked wrestling characters on all types of products and merchandise. This licensing program has expand internationally to include the United Kingdom, Italy, India, Japan, South Africa, and Australia. (www. wwe,inc. com) macrocosm Wrestling Entertainment, Inc. used horizontal integration in 2004 with the purchase of their rival, World Championship Wrestling. With the acquisition of World Championship Wrestling, it allowed World Wrestling Entertainment, Inc. o be the however major wrestling company in North America. WWE had monopolized the wrestling industry. With World Wrestling Entertainment, Inc. as the only big name in town, the wrestlers were in an awkward position. If the wrestlers were let go by the WWE or had a dispute with management over their contracts, their only alternatives would be to work for a much smaller company that could not match the kind of wages the WWE offered, or to find a new line of work. WWE Super sense impressions do not have a union to represent them.The biggest asset in the acqui sition of World Championship Wrestling wasnt the company and all intellectual property that went with it rather it was the video tape library it possessed. The WWE went on to acquire the video tape libraries of other defunct promotions like the AWA, ECW, and Jim Crockett Promotions. Collecting a majority of the wrestling video tape library in existence gave the WWE a competitive advantage. Linda McMahon has publicly said that the video library is a atomic number 82 growth project for the company.The library of video footage allowed them to test the waters of an on demand channel featuring all of the classic material. At her press conference on August 23, 2004, Linda McMahon said that the WWE 24/7 On Demand service is being counted on to provide the company a strong character reference of revenue in the future . The exciting news for fans of the WWE is that they have so much footage that only a portion of what they have now has been digitalized (November 4, 2010 World Wrestling En tertainment, Inc). When Vince McMahon and Linda McMahon opinionated to buy out all other wrestling corporations they united the sport under their own belt and logo and gained all monetary compensations. When Linda McMahon decided to start WWE On Demand 24/7, the WWE, Inc. struck gold by making wrestling able to be seen overseas via cable networks. This globalized the following of WWE fans. direct merchandise created through the many forms much(prenominal) as music, merchandise, movies, pay per views and live events, and video tapes or DVDs could be sold anywhere in the world and be profited from WWE, Inc. , their suppliers, creators and merchandisers.WWE can have a show in any of these countries and have a sold out venue and also be welcomed into these poorer countries with open fortify because of the job availability WWE created for them. WWE also sent venues overseas to support our troops, who were serving in the Iraq war, and this also established an emotional empathy type co nnection with some of WWEs followers. Because the WWE, Inc. is such a huge corporate conglomerate it is made up of an extensive board of directors and an independent audit committee. Vincent Kennedy McMahon is the Chairman and the CEO of the WWE, Inc. The board is consists of interchangeable family members and loyal friends.George Barrios is the Chief Financial Officer and oversees the WWEs financial, accounting and investor relations, strategies and their activities. Jim Connelly is the Senior Vice President of Consumer Products and oversees the WWEs global licensing, home entertainment and book and clipping publishings. Kevin Dunn is the executive Vice president of television productions and manages a state of the art television studio with 140 wrestlers and he also sits on the posting of Directors. Donna Goldsmith is the Chief Operating Officer, sits on the Board of Directors and is part of the Chief Executive Committee for the WWE.Brian Kalinowski is the Executive Vice Presid ent of all global digital media initiatives through web and mobile interactive technologies, content production and electronic commerce.

Michelle also oversees the WWEs integrated sales and sponsorship business (WWE,Inc Corporate. com). All of these people are the geniuses behind the success of this company. Without any one of them the company would struggle in that field. These people have served on this committee throughout the lifespan of the WWE.There are so many Vice Presidents and departments because the WWE is a national and international success with their hands in both means of entertainment, merchandising and promotions that are possible. Because each of these members has their own stakes in the business a nd independent audit committee of the board of directors is ask to drop sure that everything is get offning smoothly and within a budget. The independent audit committee consists of at least three directors. These directors can have no ties, flat or indirectly, with any board member, family member, worker, or wrestling persona of the WWE, Inc. o ensure that everything is maintained fairly and unprejudiced. With the auditors having no gain or stock in the WWE all audits are accurate and financially sound statements.

WWE also implements types of programs for helping retired, current or want to be wrestlers. It seems here that the WWE does try to uphold laws and contributes back to everyone in one form or another. The WWE is so extensive that it is its own United States citizen and has even had members run for senate, like Linda McMahon, and governor, Jesse The Body Ventura.Some win, some lose, no different than when a wrestler enters the ring or the WWE trying its hand in the restaurant industry. Linda McMahon stepped down as CEO of the WWE, Inc. on September 16, 2009. Linda McMahon officially announced her candidacy to run for the United States Senate for Connecticut. During this time others in office put the WWE, Inc. in the spotlight for political tirades once morest Mrs. McMahon and her qualifications. The WWE headquarters is based out of Stamford, Connecticut and this is also where the McMahons live. On November 1, 2010, President Obama and his wife Michelle visited Stamford, Connecticut and Mrs.Obama paid a visit to the WWE headquarters. After the President unexpended the WWE, Inc. was told they were under investigation for distributing merchandise near select polling loca tions. The Secretary of State for Connecticut, Susan Bysiewcz, stated that if anyone turned out to the canvass wearing any type of WWE merchandise, including a simple wrist band that the voters would be told to either remove it, cover it up or to go home and change and come back. The WWE, Inc. overlyk this to federal court of law and won because there is no law on what attire a voter should wear to vote. (Time Magazine, November 2010).On November 8, 2010 Linda McMahon lost to Richard Blumenthal and says she feels that there was corruption in the way the polls were run. Linda McMahon contributed fifty million dollars to her own campaign in the senate race. Linda McMahon is not going to return to her position of CEO at WWE, Inc. but plans on running again for a political party in the future. With Linda not returning to WWE, Inc. this leaves Vince McMahon as the chairman and now the CEO of WWE, Inc. The community that surrounds WWE, Inc. stands behind the WWE for the majority being that the McMahons contributes too many charitable factors in the community.With the President and his wife visiting Stamford it opened up many economical doors in the community promoting tourism and the trickle cause from the tourism and notoriety of the situation. No matter what changes the United States goes through in our economy WWE, Inc. still sells out every wrestling venue and almost all merchandise with their logo on it is a top seller and carries high demand for the public. Vince McMahon has received deals with people like Walt Disney to lease his wrestlers, like Duane The Rock Johnson, to star in their movies.Billions of people worldwide have an avid and loyal following of the WWE. The WWE has reached many countries outside the United States through television airing and internet access. erst again WWE is sending a wrestling venue for Christmas to our troops to show their dedication and gratitude to the men and women serving our country. This will be the first Christmas though that the WWE will take it to the troops in the United States instead of flying to Iraq (www. wrestlezone. com). WWE, Inc. has gotten the four factors of the marketing mix down to a science and the right marketing team behind them to do so effectively.The market researchers for WWE seem to be highly into utilizing environmental scanning as well. The marketing researchers have studied all the factors, such as global, technological, social cultural, and economic. WWE, Inc. really has no competitive factors to study at the moment, because there is no other competition right now therefore, WWE dominates the industry. It seems everything that the WWE has its logo on is in plenitude market production throughout the world. The WWE may have started out as niche marketing but it quickly grew into a mass frenzy. The WWE logo and name brand is now worldwide.Vince McMahon and his marketing research team are genius. They have definitely done their market segmentations to a science and hav e even made merchandise available for the poor to be able to purchase their products. The demographic segmentation is analyzed before the WWE even enters an agreement to dumbfound their show to that arena. Everywhere they have a show it is a sellout every time. With the WWE, Inc. branching into television, music, movie theaters, magazines, clothing, internet, and other merchandise they have extensively covered every means of technology to appeal to audiences and consumers.World Wrestling Entertainment, Inc. is committed to conducting its business fairly, honestly and in accordance with law. All officers, directors and other employees (collectively, including outside directors in their capacity as WWE directors, referred to herein as employees) should read this Code of Business Conduct carefully. This Code is not meant to be all inclusive, and in many cases, employees will be required to sign additional acknowledgement forms that they have read and understand various Company policie s. www. wwe,inc. com) WWE, Inc is more extensive than what I thought it would be. This corporation is a citizen in itself that started as a small business and evolved into a worldwide corporation. I do not think that Vince McMahon ever imagined the take off and demand his company would acquire. Vince McMahon was smart enough to hire tech and business savvy individuals to help ensure that he stayed on top of the game. Without his Vice Presidents in each area, this ompany would not have been able to overtake the wrestling market and branch out into every form of marketing, selling, technical areas, and merchandising that the WWE has done. This corporation is definitely one of the crush in the world. Everything it touches, besides the restaurant venue, has turned to complete profit.

How Do Poems Use Language to Create Imaginary Worlds?

Poppies by Mary Oliver and A Martian Sends A mailing-card Home by Craig Raine, with the practice of unconventional metaphors and extremely detailed observation encourage us to look upon the ordinary in a way that leads us to explore our own human nature. Unexpected connections between a previously ordinary object and something that at first seemed totally unrelated can blushing mushroom a picture of another context within which we can better examine our own existence (Hirsch).This is demonstrated quite well in A Martian Sends A postal card Home in nearly every stanza, with the alien viewpoint of everyday things leading to estimateable thought about the things we land for granted. The line, At night, when all the colours die is a particularly vivid way of describing day turning to night and implies the alien land must be either bright all the time or of another dimension where night and day have no meaning.Similarly, Poppies describes a field of battle of flowers in damage that evoke the passage of life itself, with lines such as, Of course nought stops the cold, black, curved blade from hooking forward of course, loss is the great lesson describing night falling, the goal of a flower as it wilts and the blade of a scythe, invoking images of the Grim Reaper (Wu). All these observations are made as metaphors as opposed to similes, forcing the indorser to consider each point as being the same thing as that which it is being compared to.In doing so, the reader is actually is involved in surmising the meaning of the passage through and through and through the metaphor, in collaboration with the author (Hirsch). This allows the reader to have a deeper connection with the work than merely taking in what the author is putting across, in a way that encourages extensive internal processing of the ideas more than just a literal and factual description of the ideas the author wanted to portray may have.In Poppies, when Oliver says, that cloudless is an invitation to happiness the reader is invited to think about not just poppies in a field but their own life and how they have the opportunity to work out the best of the life they lead before the curved blade of the night (Wu). In a slightly different vein, A Martian Sends A Postcard Home is suggesting that we pay closer caution to the world around us, a world in which Mist is when the sky is tired of flight and rests its soft automobile on he ground and also provokes feelings of nostalgia of when the reader was young and looked up at the clouds, the soft machines, for long periods, looking at them in a radical way (Williams 454). The poets also have an eye for incredible detail in the world around us that they use to paint a picture of a scene in layers, allowing the reader to form a three dimensional picture of the scene in their head in vivid detail.In Poppies, for example, the one field of poppies is focused on in at almost every angle the way they sway in the wind, the way the shine, their yellow hair and rough and miry gold leading to almost a baptism of flowers, washed and washed in the river of earthly delight. This seeming progression of wonder, joy, light and rebirth through the ravisher application of description after description of the one object (the field of poppies) give the reader pause to think on their own progression through life.With the occasional interjection about the darkness and the deep, blue night we are reminded that death is looming but it is the happiness we can create beforehand that is important, and we should pay attention to that detail (Wu). A Martian Sends A Postcard Home does not have, on the surface, as much of a singular message to communicate it presents us with a series of common-day objects perceived through an alien lens as completely new and how they would appear to a being with no frame of reference.However, it is just now this alien frame of reference that gives the reader a connection between their observations and their inner thoughts. Lines such as, Adults go to a punishment room with water and nothing to eat, though describing the base act of going to the toilet in a humorous manner also can lead to reflection on the nature of punishment and our own frame of reference for all things around us which we observe when we dont quite understand their context.It encourages the reader to contact harmony between our inner selves and the universe around them, which some argue is the entire function of poetry itself. Both these poems utilize this detail to create a living imaginary world for the reader to consider the ideas put forth within (Couch 12). In conclusion, when both metaphor and detail are brought together in this way, with the poetic language that is employed in the two pieces, a powerful representation of truth and harmony is communicated to the reader in a way that possibly the standard prose form cannot.In this essay I have shown how the poets, by including the reader in the process o f forming the ultimate meaning of what they are reading by the use of metaphor, together with painting their descriptions in great detail but in such a way that obscures instant recognition of what is being described, lead the reader to deeper thought about the issues raised and about their own humanity as it relates to the world around them.

Sub Saharan Africa Food Insecurity Environmental Sciences Essay

An Integrated Assessment and policy Needs Identification Abstract The batch aims to hang on in-depth comp contain of nutritious credentials in SSA in a changing mood, by incorporating socio- economical factors into scenario analysis. Furthermore, particular accent leave be placed on the regional shelter issues. The number 1 aim is of the research is to measure the concern of mood change on solid food security, while the 2nd purpose is to place the secern policy ask that should be considered in version schemes. modality transition scenarios will be simulated utilizing HadCM3 hypothetical account. Two scenarios will be examined defeat instance ( 1 % CO2 addition per annum ) and silk hat instance ( 0.5 % CO2 addition per annum ) . The projections of plain productiveness will be assessed with IMAGE or AEZ suppositious accounts. Once the demesne-use and harvest simulation theoretical accounts ar run, the estimated alteration of crop-yields will be feed into IMPA CT and BLS theoretical accounts in order to measure the wallop of clime alteration on alimentary security and hazard of hungriness. The interaction between the two theoretical accounts will capture the cross-cutting drivers for nutrient insecurity in the part. As a concluding measure, the survey will bring out socio-economic and political tendencies analysis with chief method actings literature reappraisal, informations aggregation and analysis, arrested development analysis. The overall result of the survey will be designation of the policy needs that rise consciousness, with pertinence in explicating version schemes. Keywords agribusiness, clime alteration, estimable general equilibrium, nutrient security, integrated appraisal, malnutrition, partial derivative equilibrium, hazard of hungriness, sub-Saharan Africa.1. Introduction The advert of clime alteration on nutrient security is important for developing states. Sub-Saharan Africa ( SSA ) is one of the most susceptible p arts in the universe, due to the high degrees of nutrient insecurity as a consequence of socio-economic, political and environmental force per unit areas. Harmonizing to FAO/ WFP 2010 study 1 SSA is on the 2nd topographic point ( after Asia ) in the universe in footings of think of ill-fed multitude ( 239 million people ) . However, on the first topographic point in footings of per centum undernourished of the entire population ( 30 % ill-fed ) . Recent projections for future clime alteration in SSA dismay that the land with suitableness for harvest cultivation will worsen and the land with wet emphasis will increase ( e.g. Fischer, 2005 FAO, 2009 ) . At the same clip, the part is characterized with agriculture-driven economic corpse, whereas the gloomy GDP and weakinstitutional constructions are barriers for technological development of the agricultural sector. 2. Problem Statement and Aim of the Study Recently, research workers have produced a figure of of import surveies an alyzing the impact of clime alteration on harvests productiveness ( e.g. Betts, 2005 Challinor 2009 ) and agricultural sector ( e.g. Parry, 2004 Fischer, 2005 ) . Those documents present assorted patterning models for regional and planetary appraisal of the impact of clime alteration on agribusiness and the hazard of hungriness. Furthermore, several surveies examine SSA regional scenarios for future tendencies of nutrient demand ( ground on the future population and income projections ) , nutrient supply ( based on agricultural productiveness and trade ) , land usage displacements and future clime conditions ( e.g. AIACC, 2006 Challinor, 2011 ) . However, most surveies capture chiefly harvest end product ( agricultural sector ) and pay small attending to the whole nutrient system, i.e. nutrient handiness, nutrient entree and nutrient use ( Ingram, 2005 ) . Therefore, in order to supply overall policy deductions for accomplishing nutrient security in a changing clime, we should see the drivers for nutrient insecurity in SSA, such as poorness, deficiency of instruction, scurvy market entree, unemployment, failures in belongings rights ( Scholes and Biggs, 2004 Ingram, 2005 ) . 1 The State of Food Insecurity in the institution 2010, FAO/ WFP Following the logic of the above statements, this survey aims to supply in-depth analysis of nutrient security in SSA in a changing clime, by incorporating socioeconomics factors into scenario analysis. Furthermore, particular accent will be placed on the regional security issues, such as migration and urbanisation, delicate provinces and struggles, refugee crises, HIV/ AIDS. 3. Aims of the Study and Research Questions The survey will near two chief issues. The first aim is to measure the impact of clime alteration on nutrient security. In this regard the research paper will discourse the undermentioned inquiries What is the environmental position and future clime conditions in SSA? Which are the cardinal socio-econ omic force per unit areas in SSA that should be integrated in the appraisal of clime alteration impact on nutrient security? What is the impact of clime alteration on nutrient insecurity and hungriness in SSA ( assessed by incorporating future tendencies of socio-economic conditions ) ? The 2nd aim is to place the spot policy needs that should be considered in version schemes. In this context, the following set of research inquiries is What are the barriers and chances for version in SSA? -Which are the policy needs for nutrient security in the altering clime of SSA? -Which socio-economic and political conditions should be addressed in clime alteration nutrient security policy models, based on the projections of future tendencies? 4. Scientific Methods n order to turn to the first set of research inquiries ( first aim ) , I will utilize he following research methods and instruments. 4.1. Climate Variability and Climate change over in SSA& gt Climate variableness ( I ) calcula tion of indices for variableness in monthly note limit and maximal temperature monthly rainfall ( two ) linear graphs for one-year alterations ( three ) arrested development analysis of long term trends2. & gt Climate alteration scenarios Tools and method General Circulation Models utilizing statistical downscaling Model HadCM3 ( coupled atmosphere-ocean general circulation theoretical account ) Datas extracted from IPCC 2002 Period 1961-1990 2010-2039 2040-2069 2070-2099 Base-line clime 1961-1990 ( Fischer, 2005 ) Scenarios SRES A1F1 and A2 ( worst instance = 1 % CO2 addition per annum 855ppm ) and SRES B1 and A1T ( best instance = 0.5 % CO2 addition per annum 560 ppm ) ( e.g. Fisher, 2005 AIACC, 2006 ) .The comparing between the two scenarios will turn to the uncertainties3. End product projected degrees of future CO2 precipitation temperature The end product from HadCM3 will be fed as an input in IMAGE theoretical account or AEZ theoretical account. Both theoreti cal accounts hand over land-use displacements and harvests fertilisation effects from the informationsobtained with HadCM3. 4.2. Food Security Impact Assessment Once the land-use and harvest simulation theoretical accounts are run, the estimated alteration of crop-yields will be fed into IMPACT ( partial-equilibrium theoretical account ) and BLS ( general equilibrium theoretical account ) in order to measure the impact of clime alteration on nutrient security and hazard of hungriness. The interaction between the two theoretical accounts is necessary to capture the drivers for nutrient insecurity in the part. Table 1. outlines how the two theoretical accounts chalk up to the socio-economic force per unit areas in the clime alteration nutrient security impact appraisal analysis. 2, 3 Methodology used by James Adejuwon, 2006. A Concluding Report Submitted to Appraisals of Impacts and fittings to Climate transfer ( AIACC ) , Project No. AF 23 Table 1. Models specification IMPACT Mo del BLS Model Partial-equilibrium theoretical account with focal point on agricultural sector, H2O, nutrient supply and demand. It tends to hold more item than genral equlibium theoretical accounts General equlibrium theoretical accounts take into history the linkages between agricultural and non-agricultural sectors. The theoretical account represents all economic sectors with through empirical observation estimated parametric quantities. States are linked through trade, universe market monetary value and financies Agricultural productiveness ( exogenous ) Agricultural productiveness and clime ( exogenous ) & gt agricultural production and trade ( edogenous ) & gt agricultural production and trade ( edogenous ) & gt GDP ( exogenic ) monetary values and trade ( endogenous ) & gt GDP, monetary values and trade ( endogenous ) Allows calculation of per capita KCAL, in peculiar kid malnutrition. Allows calculation of figure of people at hazard of hungriness as a portion of undern ourished in the entire population. The per centum of malnourished kids is a map of mean per capita Calorie ingestion, egg-producing(prenominal) secondary instruction, the woodland of maternal and child attention, wellness and sanitation. Thus the theoretical account gaining control broad assortment of societal issues. The estimations are based on 1 ) SRES scenarios projected income and population degrees and their distribution 2 ) ratio of the mean national nutrient supply ( including imports ) Population and GDP ( exogenic ) Population ( exogenic ) GDP ( endogenous ) Population projections captures rural-urban kineticss There are regional group theoretical accounts wich capture the economic constructions of a figure of African states by mathematical group them into oil exporters, low income nutrient importers and exporters, average income nutrient importers and exporters. 3.2. nutrient entree ( affordability income, monetary values allotment ) 3.3. nutrient use ( nutrition ) 4. Socio-economic factors ( population, GDP ) 1.Model instance 3. Food systems constituents captured by the theoretical accounts ( endogenous and exogenic variables ) 3.1.food handiness ( agricultural production, trade, imports ) 2. Climate related drivers The appraisal will be built on fivefold plot line attack ( e.g. Fisher, 2005 ) Figure 1. Multiple storyline attack 4.3. Socio-economic and political force per unit areas analysis the chief activities which will be conducted are literature reappraisal, informations aggregation and analysis, arrested development analysis. & gt Economic construction of the SSA states descriptive analysis will be provided & gt Population projections in SSA the survey will show original demographic tendencies and future projections, based on informations extracted from IIASA. The particular accent will be on migration and urbanisation, HIV/ AIDS, every bit good as educational degrees. Climate alteration induced migration will be discussed. T his analysis is closely linked to climate alteration nutrient security analytical model, since demographic tendencies are strongly correlated with environment and nutrient security. & gt Income distribution and nutrient demand trends income degrees change the consumers penchants for nutrient. As good income distribution and inequalities between states have important impact on nutrient demand ( e.g. Cirera and Masset, 2010 ) . Therefore this issue will be addressed, taking into consideration the findings of this survey every bit good as Gini coefficients for the part. & gt leanness degrees and unemployment tendencies descriptive analysis & gt Political stableness descriptive analysis on past and present struggles hazards of new eruptions refugee crisis & gt Property rights descriptive analysis of rural economic conditions & gt Poor market entree descriptive analysis of market engagement Current clime variableness, nutrient security and socioeconomic conditions Socio-ec onomic development and nutrient security with clime variableness ( no alteration ) baseline simulation Socio-economic development and nutrient security with clime alteration ( best instance scenario ) Socio-economic development and nutrient security with clime alteration ( worst instance scenario ) 5. Significance of the survey The chief parts of this thesis are expected to be Designation of applicable clime variables, tendencies and projections ( temperature, precipitation, turning season, land-use alterations ) and appraisal of clime alteration impact on harvest outputs Designation of the cardinal socio-economic factors in the analysis of the impact of clime alteration on nutrient security in the context of SSA Appraisal of the impact of clime alteration on nutrient security utilizing partialequilibrium and general equilibrium theoretical accounts Projection and spacial distribution of people at hazard of hungriness in SSA Appraisal of the socio-economic and political t endencies, closely related to nutrient security and clime alteration Designation of barriers and chances for version Designation of the policy needs that rise consciousness, with pertinence in explicating version schemes Figure 2.
