Andrew Campbell s The Power Of Myth - 861 Words

Imagine more than half of the population being denied its basic human rights. Fifty years ago, many basic human rights were a luxury, were a work in progress, or were even nonexistent. In fifty years, racism, sexism, homophobia, and many other types of prejudice have been challenged in the effort to create a civil and unbiased national community. However, despite the prodigious movements that have been at work for quite some time, each of these issues and many more still stand and exist today. I agree with Joseph Campbell’s â€Å"The Power of Myth.† Campbell’s stance applies to the issues of present day political ethics concerning human rights, more specifically, racism, sexism, and homophobia. Firstly, Campbell’s stance applies to the issues of modern political ethics, more specifically, racism. Uncountable amounts of action have taken place, and by textual legality, the United States government has developed in many ways. However, racism in the United St ates is still all too real. Being addressed the earliest in America out of racism, sexism, and homophobia, racism in the country has changed throughout centuries. As Joseph Campbell says â€Å"the moral order has to catch up with the moral necessities of actual life in time, here and now. And that is what we are not doing.† Far too many citizens, businesses, and even entire communities are racially prejudiced.

The Problems of Lima City Free Essays

The problems of Lima city Lima city is full of charm and scenic beauty, so visitors from around the world come to enjoy its typical dishes, museums,countless beaches and scenic wonders. Although Lima seems like a paradise,Not all what we find there is as as good as we think. Believe it or not, but Lima has several serious problems such as the poor public transportation,crime-violence and the bad infrastructure due to the lots of suburbs and places that have lack of lots of services. We will write a custom essay sample on The Problems of Lima City or any similar topic only for you Order Now The first and most important problem in lima is its inadequate public transportation system. Thousand of residents rely on the city’s buses and minibuses to travel throughout this large city, however the bus routes are poorly planned wich cause rush hours and traffic. For example: a person who should take the bus at 7:45 am may not take it until eight o’clock or even later. Sometimes three or more buses or minibuses arrive in bunches at time that people are waiting, but they can’t the buses because they are full. That’s why, passengers frequently become unhappy become this problem causes them to be late for work or to miss important appointments. THE TRANSPORTATION,2010 ISABEL GUERRA The second serious problem that Lima faces is crime and violence. The security in Lima has declined in the last years because police corruption have increased in line with rising level of poverty. Besides the profileration of low-income settlements wich are known as â€Å"barriadas† that have as members young people that steal.. Nowadays, we can see lots of people who are complaining about the security in this city. According to some city polls, 82% of people who live in Lima say that they were robbed at least once while they were walking around the streets of this â€Å"insecure† city. Not only that, but people are also concerned about leaving home alone. To illustrate it, more than 50% houses were robbed during the last holydays. So to wrap out this, people are not secure neigher on the streets nor at home. BULLETIN OF LATIN AMERICAN RESEARCH VOL. 27, NO. 2 The final problem is the lack of good infrastructure of housing and services in Lima. This is an interesting city that offers a good lifestyle for young, ambitious business and professional people. Also, immigrants are attracted to this city because is has tourist attractions and offers variety of typical dishes. All of these tourists or immigrants would need rental units that are in good conditions like apartments, flats and single family houses. But, unfortunately, Lima’s rental units have an old infrastructure. That’s why most of the buildings of Lima downtown are declarated in danger. Even though this, we insist on living in those old buildings. That is not secure for all the people who live, work or go to those places at all. â€Å"LIMA:BIG CITY AND BIG PROBLEM†, 2000 GILBERT A. In conclusion, Lima city must improve its public transit system for avoiding the traffic, develop a project to become places safe and housing in good conditions. In others words, Lima city must improve its image, or it will soon become just mediocre city due to the lack of administrative responsability to solve these problems. .

The Chemistry Of Swimming Pools Chemistry Essay Example For Students

The Chemistry Of Swimming Pools Chemistry Essay Pool chemical science is the application of chemical science to keep safe and clean H2O ( Hann, 1997 ) . This is achieved by modulating legion factors which include: the pH, the measure of germicide and the buffers used to defy pH alterations. The normal pH scope of a liquid pool demands to be between 7.2 and 8.0, although a scope between 7.2 and 7.8 is more practical as some germicides such as Cl are most effectual for this scope ( Hann, 1997 ) . We will write a custom essay on The Chemistry Of Swimming Pools Chemistry specifically for you for only $16.38 $13.9/page Order now The Importance of pH The pH graduated table ( see figure 1 ) is a step of the concentration of H ions ( H+ ) in a solution and is a logarithmic graduated table based on 10 ( Zumdahl, 2007 ) . Furthermore, it is represented by the equation: pH = -log ( Zumdahl, 2007 ) , and since the graduated table is logarithmic, this means that a pH addition of one value represents a H + concentration addition of tenfold. The pH graduated table ranges from one, which is really acidic, to fourteen which is really alkalic. A value of seven is impersonal, intending that a solution is neither acidic nor basic ( Hann, 1997 ) . Outline1 The pH graduated table ( figure 1 )2 Care of the pH degrees3 Chlorine for Disinfection of Pool Water4 The function of acid/base indexs5 Four Possible Indexs for Testing pH of a pool ( figure 2 )6 Index7 pH scope8 Colour shown for Acidic Solution9 Colour shown for Basic Solution10 Ka11 pKa ( -log10Ka )12 Buffer solutions13 Decision The pH graduated table ( figure 1 ) ( Environment Canada, 1992 ) A strong acid dissociates wholly in H2O to bring forth H+ ions in the signifier of H3O+ ( hydronium ion ) , whereas a weak acid does non disassociate wholly, doing a lower H+ concentration to organize ( Zumdahl, 2007 ) . Since an acid dissociates in H2O to bring forth H+ ions it is known as an H+ giver and a good illustration of this is the strong hydrochloric acid ( HCl ) . This acerb easy dissociates in H2O to organize H+ and the undermentioned equation represents this dissociation. HCl ( aq ) + H2O ( cubic decimeter ) A ® H3O+ ( aq ) + Cl- ( aq ) Because HCl is easy dissociated, it means that equilibrium lies far to the right, favoring the merchandises. On the contrary, a weak acid does non easy disassociate in H2O, intending that a reaction affecting a weak acid would non favor merchandises or reactants. In contrast to an acid, a base dissociates in H2O to organize OH- and is known as an H+ acceptor. The function of acids and bases for the care of the pH of pool H2O is of import for a figure of grounds. A pH that is excessively high or low ( above 8 or below 7.2 ) will do annoyance to the tegument ( Gothard, 2006 ) . Equally good as this, germicides such as Br and Cl require an optimal pH between 7.2 and 7.6 in order to work most expeditiously ( Hann, 1997 ) . Therefore, an addition or lessening in pH will do these germicides to work less expeditiously. Another ground for the ordinance of the pH balance is to forestall the formation of graduated table or H2O hardness sedimentations. These sedimentations are normally composed of Mg and Ca which can go detrimental to the operation of a pool as it affects the filter system, warmer and the piping ( Hann, 1997 ) . Care of the pH degrees Factors such as, the remotion or add-on of pool H2O ; waste from swimmers such as piss ; and the add-on of chemicals, affect the pH of the H2O. In order to hold a pH degree that is desirable, specific chemicals need to be added to the H2O, although it is besides possible to make a coveted pH balance by adding excess H2O to the pool ( Hann, 1997 ) . By adding extra H2O this will do the pH concentration to lower, which helps to equilibrate the pH. However, it is non ever possible to make this as different factors affect the pH, and so pool chemicals are needed. Two chief chemicals are used to take down the pH of pool H2O: Na bisulfate and muriatic acid ( hydrochloric acid ) . These chemicals both have a low pH which means that they act as a pH reducing agent . A lessening in pH occurs because the chemicals react in the H2O to bring forth more H ions, therefore increasing the sourness. The pick of which chemical to utilize depends on the size of a pool. Sodium bisulfate is normally used for little pools ( about 190 000 liters ) as it is less acidic than muriatic acid, therefore a safer option ( Hann, 1997 ) . On the other manus, muriatic acid is used for larger pools to cut down the pH because it is a more acidic. Furthermore, to raise the pH of pool H2O, Na carbonate is most normally used ( Perkins, 2000 ) . It is known as a pH increaser because it produces hydroxyl ions ( OH- ) which increases the pH of the pool H2O. Chlorine besides has an consequence on the pH of H2O ; nevertheless, it is used more normally for disinfection intents. Chlorine for Disinfection of Pool Water A safe and clean pool requires the usage of a germicide to halt the spread of catching diseases ( Hann, 1997 ) . The most common germicides used are chlorine-based merchandises as Cl is comparatively cheap and is really effectual in killing bacteriums and other harmful beings ( Perkins, 2000 ) .Chlorine gas ( Cl2 ) is neer used on its ain for disinfecting pool H2O because it is really toxic, and so would present many hazards. Therefore, compounds incorporating Cl are used alternatively and there are three chief types: Calcium hypochlorite , Na hypochlorite ( NaOCl ) and chlorinated isocyanurate. .ue32dde5e58e544cab1796062dc7f5c36 , .ue32dde5e58e544cab1796062dc7f5c36 .postImageUrl , .ue32dde5e58e544cab1796062dc7f5c36 .centered-text-area { min-height: 80px; position: relative; } .ue32dde5e58e544cab1796062dc7f5c36 , .ue32dde5e58e544cab1796062dc7f5c36:hover , .ue32dde5e58e544cab1796062dc7f5c36:visited , .ue32dde5e58e544cab1796062dc7f5c36:active { border:0!important; } .ue32dde5e58e544cab1796062dc7f5c36 .clearfix:after { content: ""; display: table; clear: both; } .ue32dde5e58e544cab1796062dc7f5c36 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .ue32dde5e58e544cab1796062dc7f5c36:active , .ue32dde5e58e544cab1796062dc7f5c36:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .ue32dde5e58e544cab1796062dc7f5c36 .centered-text-area { width: 100%; position: relative ; } .ue32dde5e58e544cab1796062dc7f5c36 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .ue32dde5e58e544cab1796062dc7f5c36 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .ue32dde5e58e544cab1796062dc7f5c36 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .ue32dde5e58e544cab1796062dc7f5c36:hover .ctaButton { background-color: #34495E!important; } .ue32dde5e58e544cab1796062dc7f5c36 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .ue32dde5e58e544cab1796062dc7f5c36 .ue32dde5e58e544cab1796062dc7f5c36-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .ue32dde5e58e544cab1796062dc7f5c36:after { content: ""; display: block; clear: both; } READ: Mesothelima EssayWhen these compounds are added to the H2O a reaction occurs, organizing a chemical called hypochlorous acid ( HOCl ) which is an oxidising agent and hydrochloric acid ( HCl ) . Since hydrochloric acid is formed, this will intend that the pH of the pool H2O decreases somewhat. Cl2 + H2O A ® HOCl + HCl The hypochlorous acid kills the bacterium in the H2O by oxidization and the HOCl can easy go dissociated to from H ions ( H+ ) and hypochlorate ions ( ClO ) . HOCl a† Ã¢â‚¬  H+ + ClO- Both the hypochlorous acid and the hypochlorite ions are considered as free Cl , which is the chemical species responsible for killing bacteriums in the H2O ; nevertheless, the hypochlorous acid is far more efficient ( Daniels, 1973 ) . The dissociation of the hydrochlorous acid is an equilibrium reaction, intending that the reaction can happen in either way. Furthermore, the pH of the H2O affects the way in which the reaction returns, therefore act uponing the effectivity of the germicide. An addition in pH would intend that there are more H+ ions which would do the reaction to continue to the right, intending that less hypochlorous acid is present in the H2O. Furthermore, a lessening in pH will do the reaction to continue to the left, intending that more hypochlorous acid is produced which increases the effectivity of the Cl as a germicide. To be able to find the pH of a solution, the usage of acid/ base indexs are needed. The function of acid/base indexs In order to maintain the pH of pool H2O in the right scope it is necessary to utilize an acid/base index to prove the pH. An acid/base index is a substance that gives an accurate indicant of the sourness or alkalinity of a solution ( Dice, 2008 ) . Besides, an index is a weak acid represented by HIn ( Zumdahl, 2007 ) and it can be written as an equilibrium look: HIn ( colourless ) a† Ã¢â‚¬  H+ + In- ( pink ) where the In- is the basic signifier of the index. The HIn and the In- both show a different coloring material which corresponds to the pH of the solution. As an illustration, the index phenolphthalein is colorless in an acidic solution and pink in a basic solution. This means that the HIn represents the colourless molecules, whereas the In- represents the pinkmolecules. Since an index is in equilibrium, an acidic solution would do an addition in H+ concentration, therefore switching equilibrium to the left. Likewise, in a basic solution the OH- ions cause a lessening in H+ , which shifts equilibrium to the right. The equation for an index can be written as an equilibrium changeless look. Ka = / This look can be rearranged to organize an equation which is really utile in happening the terminal point of an index, which is the point at which colour alteration occurs. Ka / = / The ratio between the In- and the HIn will demo the coloring material of the index ; for illustration if there is one In- pink molecules for every one hundred colourless it means that the solution will look colourless. However, for the human oculus to observe the coloring material alteration, the coloring material alteration occurs at a pH where the ratio of In- to HIn is 1:10 for an acidic solution, whereas for a basic solution the alteration will happen at a ratio of 10:1 ( Zumdahl, 2007 ) . There are a assortment of indexs all of which are utile for specific pH ranges, and so it is of import to utilize an appropriate index for mensurating pool H2O pH. The following tabular array ( figure 2 ) shows four different acid/base indexs that could be perchance used to help with pool direction. Four Possible Indexs for Testing pH of a pool ( figure 2 ) Index pH scope Colour shown for Acidic Solution Colour shown for Basic Solution Ka pKa ( -log10Ka ) Bromthymol Blue 6.0-7.6 Yellow Blue 1.0 x 10-7 7.0 Cresol Red ( alkaline ) 7.2-8.8 Yellow Reddish-purple 1.0 x 10-8.32 8.32 Phenol Red 6.8-8.4 Yellow Red 1.0 x 10-7.9 7.9 Phenolphthalein 8.3-10 Colourless Tap 1.0 x 10-9.3 9.3 From the tabular array it can be seen that phenol ruddy, cresol ruddy and bromthymol blue would wholly be utile indexs as their pH scope is rather close to the pH scope of a pool which is 7.2-7.8. Since phenolphthalein s scope is 8.-10, this index would be the least effectual as is non really near to the pool scope, whereas the other indexs each have similar scopes that are within the scope. To verify the pH at which an index alterations colour, the equation from above can be used: .u898691d9cb75fdf62c45b84aeea206fb , .u898691d9cb75fdf62c45b84aeea206fb .postImageUrl , .u898691d9cb75fdf62c45b84aeea206fb .centered-text-area { min-height: 80px; position: relative; } .u898691d9cb75fdf62c45b84aeea206fb , .u898691d9cb75fdf62c45b84aeea206fb:hover , .u898691d9cb75fdf62c45b84aeea206fb:visited , .u898691d9cb75fdf62c45b84aeea206fb:active { border:0!important; } .u898691d9cb75fdf62c45b84aeea206fb .clearfix:after { content: ""; display: table; clear: both; } .u898691d9cb75fdf62c45b84aeea206fb { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u898691d9cb75fdf62c45b84aeea206fb:active , .u898691d9cb75fdf62c45b84aeea206fb:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u898691d9cb75fdf62c45b84aeea206fb .centered-text-area { width: 100%; position: relative ; } .u898691d9cb75fdf62c45b84aeea206fb .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u898691d9cb75fdf62c45b84aeea206fb .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u898691d9cb75fdf62c45b84aeea206fb .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u898691d9cb75fdf62c45b84aeea206fb:hover .ctaButton { background-color: #34495E!important; } .u898691d9cb75fdf62c45b84aeea206fb .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u898691d9cb75fdf62c45b84aeea206fb .u898691d9cb75fdf62c45b84aeea206fb-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u898691d9cb75fdf62c45b84aeea206fb:after { content: ""; display: block; clear: both; } READ: Diabetes EssayKa = / Sample computation for the index phenol red: ten 10-7.9 = / First, the pH at which the index will alter for an acidic solution will be found.

The pH at which the coloring material alteration occurs in a basic solution can besides be calculated, nevertheless, the ratio of In- to HIn will be 10:1 as there must be more In- molecules for a color alteration to happen. ten 10-7.9 = ( 10 ) / ( 1 ) = ( 1.0 x 10-7.9 ) / 10 = 1.26 ten 10-9 pH = -log ( 1.26 x 10-9 ) = 8.90 pH = 8.9, which is the point at which the coloring material alteration will be ruddy. However, the value is non precisely the same as the existent value because it is an estimate and is non exact. Phenol red s pH scope is the closest to the pool s scope when compared to the other three indexs, which means that it is the most appropriate for proving pool H2O. Acid/base indexs are non merely of import for finding the pH of a solution, but are besides important for happening a pool s buffering capacity, as the pH of a solution must be known. Buffer solutions To help in the care of pool pH, it is necessary to utilize a buffer solution. A buffer solution is any solution which resists fluctuating alterations in pH, doing it easier to maintain pool H2O in the appropriate pH scope ( Hann, 1997 ) . The buffering ability of a pool is dependent on the entire alkalinity, which is the step of the measure of alkalic substances present in the H2O ( Hann, 1997 ) . Calcium carbonate is the chief compound which makes up the entire alkalinity and when it is dissolved in H2O it produces carbonate ions which act as a buffer. CaCO3 ( s ) a† Ã¢â‚¬  Ca2+ + CO32- The carbonate ions work as a buffer because they neutralise the H+ ions formed when an acid is added. To find the buffering ability of a solution, the Henderson-Hasselbalch equation can be used. This equation is derived from the equilibrium invariable for the dissociation of a weak acid which is given by the equation: Ka = ( ) / where A- is the coupled base, and HA is a simple acid. By taking the logarithm of both sides and rearranging it will give the undermentioned equation: -log = -logKa + log ( / ) Since, -log = pH and -logKa = pKa, the equation can be written as: pH = pKa + log ( / ) This equation is known as the Henderson-Hasselbalch equation and can be used in respects to pool chemical science to be able to cipher the buffering capacity, which is the measure of hydroxide ions ( OH- ) that can be absorbed by the solution before a important pH alteration occurs. Additionally, the magnitude of and find the buffering capacity of a solution. The most effectual buffer is one that has a ratio of one, as this will do no alteration in pH ( Zumdahl, 2007 ) . The undermentioned computation will demo a possible application of buffer chemical science for the pool. pH = pKa + log ( / ) A concentration of 0.002M Hydrochloric acid is added to a solution with a pH of 7.6 and a Ca carbonate concentration of 2.11 ten 10-8M. Hypochlorous acid is besides present in the H2O and its pKa is 3.5 ten 10-8. 7.6 = 3.5 ten 10-8 + log ( / ) = 7.46 Therefore, the pH of the solution has decreased, which means that the solution does non hold the best buffering capacity. The best buffer solution would necessitate to hold a ratio of 1:1 which would do the pH to remain about the same. Decision The chemical science involved in the direction of backyard swimming pools is an of import facet and needs to be understood in order to keep a safe swimming pool environment. A pH scope between 7.2 and 7.8 is recommended and so an apprehension of how to take down and raise the pH is indispensable. Chlorine can be used as a germicide of pool H2O ; nevertheless, it needs to be known that the reaction signifiers hydrochloric acid which lowers the pH. Thus, an add-on of a pH increaser such as Na carbonate is needed as this increases the figure of OH- molecules in the H2O, which increases the pH. Furthermore, the usage of pH indexs is necessary in commanding the pH, as they give an accurate reading of the pool s pH. However, each index has a different pH scope and so it is of import to take the appropriate index for the pool. Besides, a pools buffering ability is important in maintaining the pool s pH in balance. Poor buffering capacity means that an add-on of an acid or a base will do the pH to dramatically fluctuate, doing it hard to pull off a pool. Entire alkalinity is the step of a pool s buffering ability and Ca carbonate is frequently used to increase the buffering ability.

Rocky Mountains Or Rockies Essays - Free Essays, Term Papers

Rocky Mountains Or Rockies Essays - Free Essays, Term Papers Rocky Mountains Or Rockies Rocky Mountains or Rockies, great chain of rugged mountain ranges in western North America, extending from central New Mexico to northeastern British Columbia, a distance of about 3220 km (about 2000 mi). The Great Basin and the Rocky Mountain Trench, a valley running from northwestern Montana to northern British Columbia, border the Rockies on the east by the Great Plains and on the west. The Rocky Mountains form part of the Great, or Continental, Divide, which separates rivers draining into the Atlantic or Arctic oceans from those flowing toward the Pacific Ocean. The Arkansas, Colorado, Columbia, Missouri, Rio Grande, Saskatchewan, and Snake rivers rise in the Rockies. The Rockies may be divided into four principal sectionsSouthern, Central, Northern, and Canadian. The Southern Rockies, which include the system's broadest and highest regions, extend from central New Mexico, through Colorado, to the Great Divide, or Wyoming, Basin, in southern Wyoming. This section, which encompasses Rocky Mountain National Park, is composed chiefly of two northern-southern belts of mountain ranges with several basins, or parks, between the belts. The component parts include the Sanger de Crisco and Laramie mountains and the Front Range, in the east, and the San Juan Mountains and the Swatch and Park ranges, in the west. The Southern Rockies include the chain's loftiest point, Mount Elbert (4399 m/14,433 ft high), in central Colorado. More than 50 other peaks of the Rockies rising above 4267 m (14,000 ft) are in Colorado; these include Longs Peak (4345 m/14,255 ft high) and Pikes Peak (4301 m/14,110 ft high). The Central Rockies are in northeastern Utah, western Wyoming, eastern Idaho, and southern Montana. They encompass the Bighorn; Bear tooth, and Unite Mountains and the Absaroka, Wind River, Salt River, Teton, Snake River, and Wasatch ranges. The Unite Mountains are the only major portion of the Rockies that extends east west rather than north south. Among the peaks of the Central Rockies, which include Grand Eton and Yellowstone national parks, are Gannett Peak (4207 m/13,804 ft high), Grand Eton (4197 m/13,771 ft high), and Fremont Peak (4185 m/13,730 ft high). The Northern Rockies are in northern Idaho, western Montana, and northeastern Washington. They include the Saw tooth, Cabinet, Salmon River, and Clearwater Mountains and the Bitterroot Range. The loftiest points in the section, which includes Glacier National Park, are Granite Peak (3901 m/12,799 ft high) and Borax Peak (3859 m/12,662 ft high). The Canadian Rockies, located in southwestern Alberta and eastern British Columbia, are composed of a relatively narrow belt of mountain ranges that terminates at the Lizard River lowland in northeastern British Columbia. The peaks of the section, which takes in Banff, Jasper, Kootenay, Waterton Lakes, and Yoho National Parks, include Mount Robson (3954 m/12,972 ft high), Mount Columbia (3747 m/12,294 ft high), and The Twins (3734 m/12,251 ft high). Slopes generally are very steep, and there are numerous glaciers. The Rocky Mountains are a geologically complex system with jagged peaks as well as almost flat-topped elevations. The Rockies were formed mainly by crustal uplifts in comparatively recent times, during the late Cretaceous and early Tertiary periods, and later were reshaped by glaciation during the Pleistocene Epoch. Today the Rockies receive moderate amounts of precipitation, most of which occurs in the winter. Lower levels are covered chiefly by grassland, which gives way to extensive forests, principally of conifers. Above the woodland is a zone of grasses and scattered shrubs. Most peaks have little vegetation around the summit, and some have a year-round cap of snow and ice. The Rockies are sparsely populated for the most part and contain few cities. The principal economic

Reinforcement in Applied Behavior Analysis

Reinforcement in Applied Behavior Analysis Reinforcement can mean lots of things to different people. In the science of Applied Behavior Analysis, it has a very specific and narrow definition. That it is narrowly defined by its function does not narrow the range of possibilities: it can be money, smiles, warm water or an infinite number of things. Reinforcement and ABA Reinforcement is any stimulus (something that a sensory organ can experience) that will increase the likelihood of a behavior reappearing. Can a high pitched noise be a reinforcer? Yes, if the organism finds it pleasurable. Can a punch in the face lead to reinforcement? Yes, if it eliminates some of the throbbing pain of a toothache. A practitioner of Applied Behavior Analysis will seek out the function of a behavior by questioning how a consequence of the behavior creates reinforcement for the client/patient/student. Reinforcement on a Continuum Reinforcement happens along a continuum from primary reinforcement ( food, water, other physical reinforcers ) to social reinforcers, such as social attention, praise or recognition. Many children with disabilities do not respond to secondary or social reinforcers since they dont actually function to provide reinforcement. A child who has spent money will find a quarter reinforcing whereas a child with severe autism or cognitive disabilities will not find a quarter reinforcing. Typical children and most adults generally respond to secondary and social reinforcement. We work long hours for monetary amounts that are deposited electrically into bank accounts we access online or with a credit card. The goal of ABA is to move children along the continuum to secondary reinforcers, so that they, too, will work for a paycheck and learn to make choices about how they use the result of their own labor. For many children with disabilities, that needs to be taught, and it is often learned by pairing primary reinforcers with social or secondary reinforcers. Choosing Reinforcement Once the replacement or target behavior is defined in an operational way, the ABA practitioner needs to find reinforcers that will drive the students/clients behavior. Children with significant disabilities may need to be reinforced with primary reinforcers, such as favorite foods, but unless this reinforcement is paired with social or secondary reinforcers, it can create an unhealthy and unsustainable reinforcement strategy. Many sensory reinforcers can be successful with children with significant disabilities, such as low functioning autism when you can discover what sort of sensory toy appeals to children. I have used buzzing toys, spinning toys, and even water play successfully as reinforcers with students with significant language and developmental disabilities. Some of these children like to play with musical toys. It is important to create a rich menu of reinforcers, and continuously add items into a childs reinforcement menu. Reinforcement, like all matters of taste, change. Also, students can sometimes become satiated by too much of a single reinforcer, whether its Blues Clues or Reeses Pieces. Often, practitioners will begin with a Reinforcer Assessment which can be done a number of different ways. A successful practitioner will ask parents or caregivers for the childs preferred foods, television shows or characters, activities, and toys. These are often a good place to start. Reinforcers can then be presented in a structured or unstructured way. Sometimes two or three items are placed in front of the child at a time, often pairing preferred items with new items. Sometimes you can present a child with a large number of reinforcers at one time, and eliminate items a child ignores. Reinforcement Schedules Research has evaluated regular reinforcement (on a schedule, from each correct response to every three or four responses) as well as variable reinforcement (within a range, such as every 3 to 5 correct behaviors.) It has shown that variable reinforcement is the most powerful. When a child/client discovers that they are reinforced for every third correct response, they rush to the third response. When they dont know exactly when they will be reinforced, they tend to have stronger responses, tend to generalize across environments and tend to retain the new behavior. The ratio is important: too high a ratio too early may not help the subject learn the target behavior, too low a ration may lead to reinforcement dependence. As a child/subject learns the target behavior, the practitioner can thin the reinforcement schedule, increasing the ratio, and spreading out the reinforcement over more correct responses. Discrete Trial Teaching Discrete Trial Training or Teaching (more acceptable now) is the principal delivery method for instruction in ABA, though ABA is increasingly employing more naturalistic methods, such as modeling and role-playing. Still, each trial is a three-step process: Instruction, Response, and Feedback. The reinforcement happens during the feedback part of the trial. During feedback, you want to name the target behavior ¸ and in initial trials, you want to begin with a one to one reinforcement schedule. You will reinforce every correct response in a one to one schedule, so your student understands that he/she gets the goodies every time they give you the behavior you want. Success in Reinforcement The most successful reinforcement is when a child/client begins to reinforce themselves. That is the intrinsic reinforcement that some of us receive for doing the things that we value or enjoy the most. But lets face it. None of us would go to work without the paycheck, though many of us accept a lower paycheck (as lowly teachers) because we do love what we do. Success, for many students with disabilities, is to learn to find social interaction, praise and appropriate social interaction as reinforcers, so that they acquire age-appropriate social skills and function. Our hope is that our students will gain the level of social and cognitive function that will give them full and meaningful lives. Appropriate reinforcement will help them achieve that.

Volly 2 Essay Example | Topics and Well Written Essays - 500 words

Volly 2 - Essay Example In this touch ten drill the defenders run hitting line with all the hitters. The coach will toss the ball to the setter and the setter sets the ball to any of the hitter he likes. The hitter will try to avoid all the defenders while smashing the ball. The defenders can start from anywhere in the court for effectively blocking the smashes (X-hitters, C-Coach, D-Defender, S-Setter) (Volleyball.com). The figure given below is another form of touch ten defensive drill. This drill teaches aggressiveness along with improving reflex reaction times. Reflexes and reflex reactions are important in every sports and volleyball is also not an exception. Here X stands for defenders and C for the coach. Coach hit the ball repeatedly to any of the three defensive players. There will not be any clue about who is going to receive the ball from the coach. All the defenders should be ready to receive the ball every time when the coach hit the ball. The coach on the other hand mixes his shot with less power, more power, less accurate, more accurate, and also he uses variety of swings also in each of the shots he make (Volleyball.com). This drill is intended for strengthening of offense. This is intended for closing the hole between the blockers by the smasher. It requires blockers at one side and the setter and the hitters on the other side. The ball tossed by the coach to the setter, sets to an outside hitter. The hitter should try to smash the ball between the blockers. The middle and the outside blocker start the drill by standing next to one another so that the timing is not an issue. This drill can be practiced using two and three blockers. Initially the drill starts with two blockers and then in order to increase the difficulty level in hitting the ball, instead of two, a third blocker is also used (Volleyball Plays and
