Physiological Impacts of World War Two Essay Example for Free

Physiological Impacts of World War Two Essay When a soldier enlists into the military forces they know they are going in to fight for their country and freedom for everyone. They spend months training and preparing for the war and what to come. They learn to fight, shoot, and kill enemies, but what they do not learn is how to cope with the after math of the war. Soldiers in war every year come home with many post traumatic effects from what they had witnessed. During world war two this was known as shell shock; however what can be concluded is that world war two impacted the soldiers emotionally and physiologically from the time they entered to post war. World War Two was one of the biggest struggles nations everywhere have ever seen. â€Å"It killed more people, costs more money, damaged more property, and affected more people†¦than any other war in history† (The History on the Net Group). People everywhere were in panic when the War started. With all the damage done during the war it can be imagined how the soldiers were traumatized by losing their fellow soldiers. â€Å"The number of people killed, wounded, or missing between September 1939 and September 1945 can never be calculated, but it is estimated that more than 55 million people perished† (The History on the Net Group). Soldiers were devastated by the tragedies that occurred at the time of war. However, before the war started there were a lot of causes that went into why everything ended up in war. World War Two began in September 1939 when Britain and France declared war on Germany following Germany’s invasion of Poland. The war was triggered by Germany’s invasion of Poland but the causes of the war are far beyond this fact. After World War One had occurred Woodrow Wilson, the president of the United States of America wanted to make a treaty on his four point plan to bring peace to Europe. Other countries involved in this treaty did not have the same idea as President Wilson. George Clemenceau wanted revenged. He wanted to make sure Germany would never be able to start a war again. When Germany received this treaty they were very surprised with the terms. The terms included, war guilt clause, which meant Germany accepted all the blame for  World War One. Reparations, Germany had to pay millions in damage from the war. Disarmament, Germany could not have tanks or air force and land was taken away from them and given to other countries. The Germans were not happy with this treaty and thought of it as very harsh. However the Germans took responsibility and continued on in hope to get revenge later. In 1919, to help keep the world safe for democracy the League of Nations was set up. League of Nations would intend that if there were disagreements between countries they would negotiate rather than fight. The failure of the League of Nation can be summarized by points such as, not all countries joining in such as Germany as a punishment and Russia because of the spread of communism. The League of Nations had no power or any army. Countries were hesitant to get involved with an aggressive country and taking direct action against them. These things led to the fall of the League of Nations. People were angry because they did not want to cut off resources with other countries, even if they were aggressive because during the late 1920’s depression hit most of them. â€Å"The depression destroyed the market for imported silk from Japan, which had provided the country with two fifths of its export income’’ (The History on the Net Group). Economic problems played a fundamental part in the cause of World War 2. Germany, one of the poor countries became crippled in power and vulnerable. When Adolf Hitler came into power he immediately began placing blame on other countries and making Germany at the top of resources again. All these aspects lead to the start of World War two in Europe. As the war in Europe continued President Franklin D. Roosevelt told America he did not want to get involved. He thought it was better to stay neutral in this matter and let them handle their own battle. The United States decided to eventually join the war after the bombing of Pearl Harbor, however the issues had started years before Pearl Harbor was attacked. It starts with the Japanese invasion of Manchuria, China. The Japanese invade Manchuria on September 18th, 1931. China was in the middle of a depression, so the Japanese had the upper hand. When Russia found this out they were enraged meaning America was as well, being alliances with Russia. Also, â€Å"the Japanese invading China violated the Kellogg-Briand Pact of 1928 which renounced war as national policy† (Ketchum). The United states told Japan  if they dont get out of China, they would stop trading oil with them. Japan stayed in China so the U.S stopped trading oil. Japan disliked this and held a grudge on America for years. Besides this, The US was already trading with other countries through the Lend-Lease Act, a document allowing the US to lend countries like Britain war materials in exchange for money. Germany was also angry that America was helping their enemies. As a result the Nazi’s decide to sink the U.S supply ships to help keep them from sending resources to other countries. However, President Roosevelt did not want to enter war until the attack of Pearl Harbor, Hawaii occurred. This pushed the United States into the war officially on December 8, 1941. Right after we entered the war Hitler declared war on the United States. Followed by a United States declaration of war against Germany, and then the United States was fully involved in the war. America did not want to go to war but when America was targeted they decided to counter attack, however they did not plan on going to war with Germany but once they did it lead to one of the biggest and bloodiest wars of all time in history. My grandfather, Edward Weil was lucky and un lucky enough to be able to experience World War 2. As a veteran of war he tells me all his stories about what the war was like. â€Å"The war was a very hard time.† He tells me, â€Å"it was rough but it also brought the nation closer together and America’s pride shined.† When I asked my grandfather why he joined the war he has told me about the attack of pearl harbor and how everyone had to stand for the pledge of allegiance out of respect and when he put his hand to his heart a navy officer came up to him and told him, â€Å"You would look very good in a uniform.† It really made my grandfather look at what he wanted to do and how he wanted to protect his nation. At the same time joining the war also impacted him in a negative way. During the war my grandfather was nervous but knew this was what he wanted to do. He saw the Japanese bomb his mother ship and his sailors being killed and put on the edge of the deck to take back and bury. These experiences get scarred into soldiers minds forever. They cannot escape what they saw and those horrific actions done to one another. My grandfather was only 17 years old when he entered war. He wanted freedom and security for the American people. However, as a young teenage boy still the war affected his emotions and to this day it is still  a very sentimental and emotional topic to him. During my interview with my grandfather as I talked about what he wished he could change about the war, he started to tear up and told me about all the people lost to the war and his friends. His ship pulled next to another ship while it was burning and the people were asking for help and they tried to save as many people as they could. My grandfather even lost his left hearing due to the war. He is very proud to show his metals from the war and how he helped our nation. My grandfather is very proud to be a world war to veteran.

Effects Of Concentration On The Absorbance Values

Effects Of Concentration On The Absorbance Values Abstract: A 0.2100 M stock solution of cobalt (II) chloride hexahydrate was analyzed using UV-Vis spectroscopy. A series of dilutions of the stock solution were made to analyze the effects of concentration on the absorbance values of cobalt (II) chloride hexahydrate using the UV-Vis spectrophotometer. The copper (II) chloride hexahydrate was found to have the highest absorbance value at an average wavelength of 511.02 nm. The average molar extinction coefficient for copper (II) chloride hexahydrate was found to be 4.5172. Spectroscopic analyses of dilutions of the stock solution were used to create a calibration curve of absorbance versus concentration of the cobalt chloride hexahydrate solution. A solution of unknown concentration was analyzed using the UV-Vis spectrophotometer. The calibration curve was used to determine that the unknown had a concentration of 0.1250 M. Introduction: Ultraviolet/Visible (UV-Vis) spectroscopy analyzes electronic transitions between atoms and molecules. Spectra are produced when electrons in molecules or atoms move from one electronic energy level to another of higher energy. In doing so, the absorbed energy is equal to the difference between to the two levels. Compounds that absorb light in the visible region are colored. Compounds that absorb light only in the ultraviolet region are colorless. Inside a UV-Vis spectrophotometer there are usually two light sources, a tungsten lamp for the visible region (380-800 nm) and a deuterium lamp for the ultraviolet region (10-380 nm). The light source produces a white light ray which contains all wavelengths (all colors). The light ray directed to a monochromator by a mirror. The monochromator is used to separate light into specific wavelengths. Each wavelength corresponds to a different color. The instrument scans through the UV-Vis spectrum, sending different wavelengths of light through the sample. A single wavelength passes into the modulator, which consist of a rotor with mirrors that splits the light into two beams. One beam passes through the sample cell, while the other passes through the reference cell. Both sample and reference beams are redirected by mirrors into a detector. The detector compares their intensities of the two beams and sends a signal to the computer that controls the instrument. The signal is defined as abs orbance, which is a measurement of how much light is being absorbed by the sample at that particular wavelength. The Beer-Lambert law states that absorbance (A) is proportional to concentration of the absorbing species and path length of the medium over a certain time: In equation 1, is the molar extinction coefficient and has units of, the path length of the medium or L, is reassured in centimeters or cm and the concentration of the absorbing species has units of molarity or M. In this experiment a solution of cobalt (II) chloride hexahydrate was analyzed using UV-Vis absorption spectroscopy. The purpose of this experiment is to create a calibration curve of absorbance versus concentration by making series of dilutions of cobalt (II) chloride hexahydrate. The calibration curve will then be used to determine the concentration of an unknown sample. The molar extinction coefficient for cobalt (II) chloride hexahydrate will also be determined using the absorption at the concentrations of each dilution. Experimental Procedure: Using the analytical balance, 2.5072 g of cobalt (II) chloride hexahydrate were weighed and placed into a 50 mL beaker. The purple solid was dissolved inside the beaker using 15 mL of distilled water. The purple liquid was then transferred to a 50 mL volumetric flask with the aid of a funnel. The beaker was then rinsed with another 15 mL portion of distilled water to collect any remaining cobalt (II) chloride hexahydrate left behind and then was transferred to the 50 mL volumetric flask using the same funnel. Additional 20 mL of distilled water were added to the 50 mL volumetric flask to create the stock solution of cobalt (II) chloride hexahydrate. Dilutions of the stock solution were made by transferring 2, 4, 6 and 8 mL of the stock solutions to four labeled 10 mL volumetric flasks. Distilled water was added to fill each flask to the line. The absorbance for each solution was calculated using spectrophotometer. Before any samples were analyzed, a sample containing just water was used to blank the instrument. A quartz cuvette was filled with distilled water and covered. The blank sample was placed in the sample holder in the back of the spectrophotometer. Using the program, the spectrophotometer parameters were set to scan the sample from 650 nm to3 90 nm. The program was also designed to automatically let the user know which sample to place next into the sample holder. After the blank sample was analyzed, the cuvette was rinsed with distilled water first and then with a small portion of the stock solution. The cuvette was then filled with a portion of the stock solution, covered and analyzed using the spectrophotometer. This procedure was repeated for all dilutions. After each analysis, the cuvette was first rinsed with distilled water and then rinsed with a small portion of the following sample. Results: In order to analyze the sample using the spectrophotometer, the compound needs to be present in the aqueous form. The copper (II) chloride hexahydrate appeared purple as a solid. After the 2.507 grams of copper (II) chloride hexahydrate were dissolved in 50 mL of distilled water, the compounds color changed from a dark purple to a pink colored solution. The concentration of the copper (II) chloride hexahydrate stock solution was found using the molecular weight of the compound, the amount of compound used and the amount of distilled water used to dissolve it. Table #1 shows the how the concentration of the copper (II) chloride hexahydrate stock solution was found. When the dilutions were made by taking 8, 6, 4 and 2 mL of the stock solution, the concentration of each dilution decreased proportionally to the amount of stock being added. The intensity of the pink color of each dilution also decreased as the amount of milliliters of distilled water increased. Table # 2 shows how the concentration for each dilution of the stock solution was calculated. The software was programmed to analyze the solutions in the following order, the blank sample, the stock solution (0.2100 M), the 0.1680 M dilution, the 0.1260 M dilution, the 0.0840 M dilution and 0.0420 M dilution. All samples were analyzed in the spectrophotometer, by using quartz cuvettes. The blank sample had no visual results as expected. When the 0.2100 M stock solution was analyzed by the spectrophotometer, the computers monitor displayed the formation of a graph starting at 650.00 nm on the x-axis and 0.00 Absorbance on the y-axis. After the graph passed 580.00 nm, the graphs absorbance values started to increase exponentially. The maximum absorbance value was recorded at 0.9993 and it occurred at maximum wavelength of 511.34 nm. After the was passed, the graphs absorbance values started to exponentially decreased until the graph reached 420.00 nm, after 420.00 nm the graphs absorbance values displayed a slightly constant pattern until the end of the graph at 380.00 nm. Similar results were observed for all the dilutions. The 0.16800 M dilution analysis showed a maximum wavelength of 510.92 nm and a maximum absorbance value of 0.7266. The 0.12600 M dilution analysis showed a maximum wavelength of 511.11 nm and a maximum absorbance value of 0.5703. The 0.0840 M dilution analysis showed a maximum wavelength of 510.98 nm and a maximum absorbance value of 0.4024. The 0.0420 M dilution analysis showed a maximum wavelength 510.75 nm and a maximum absorbance value of 0.1758. Table # 3 summarizes all the maximum wavelengths and absorbance values for the stock solutions and all its dilutions. Figure # 1 (appendix-pg 14) illustrates the graph for each solution. Using the data from table # 3, a calibration curve of absorbance versus concentration can be created. Figure # 2, the calibration curve can be found in the appendix section, page 13. The molar extinction coefficient for copper (II) chloride hexahydrate can be found using data found in Table # 3 and the Beer-Lambert law. By algebraically manipulating the Beer-Lambert equation (A = ÃŽ µ * L *c), the molar extinction coefficient (ÃŽ µ) for copper (II) chloride hexahydrate can be determined by: ÃŽ µ = A / L*c. The molar extinction coefficient for all the solutions can be found in Table # 4. The average molar extinction coefficient for copper (II) chloride hexahydrate was found to be 30445. A solution of unknown concentration was analyzed using the spectrophotometer following the same procedure as all other solutions. The solution of unknown concentration was found to have a maximum wavelength of 511.49 nm and a maximum absorbance value of 0.5715. The concentration of the unknown sample was determined using the equation of the line found on the calibration curve (page 13-Appendix). The unknowns absorbance value of 0.5715 was used as the y-value and the equation was solved for its correspondent x-value or concentration. The unknowns concentration was found to be 0.80 M. Table # 5 shows how the equation of the line from the calibration curve was used to determine the concentration of the unknown. Figure # 3 in the appendix section-pg 14, is a graph of all the solutions tested. In figure # 3, the unknown is easier to identify because the graph is in a landscape format and the x-axis increases by a factor of 20 nm as opposed to a factor of 50 nm in Figure # 1. Conclusion: The spectroscopic analysis of copper (II) chloride hexahydrate made the students familiar with operating a spectrophotometer. Dilutions to a stock solution of copper (II) chloride hexahydrate were made to examine how different concentrations of the compound affected the absorbance values of each sample. The copper (II) chloride hexahydrate was found to have the highest absorbance value at an average wavelength of 511.02 nm. A calibration curve for the concentration versus absorbance of copper (II) chloride hexahydrate was created using the data obtained from stock solution and dilutions using the spectrophotometer. A unknown sample was found to have a concentration of 0.1250 M. The concentration of the unknown was determined by using the calibration curve along with the data obtained from the spectrophotometer. The average molar extinction coefficient for copper (II) chloride hexahydrate was found to be 4.5172. The value for the molar extinction coefficient was determined using the t heory behind Beer-Lambert law and maximum absorbance values from the spectrophotometer. Discussion A different approach to determine the concentration of the unknown involves using the average molar extinction coefficient for copper (II) chloride hexahydrate found in table # 4. By algebraically manipulating the Beer-Lambert equation a formula for concentration can be derived: c = http://www.800mainstreet.com/elsp/Elsp.html

Examining Matrices Of Relation

Examining Matrices Of Relation History of matrix had to be going back to the ancient times, because it is not applied until 1850. Matrix is the Latin word for womb, and is same in English. It can also mean something is formed or produced. Matrix was introdeced by James Joseph Sylvester,who have brief career at the University of Virginia, which came to an abrupt end after an enraged Sylvester, hit a newspaper-reading student with a sword stick and fled the country, believing he had killed the student! An important Chinese text from between 300 BC and AD 200, Nine Chapters of the Mathematical Art (Chiu Chang Suan Shu), gives the use in matrix method to solve simultaneous equations. And this is origins of matrix. Too much and not enough, is the concept of a determinant first appears in the treatises seventh chapter. These concepts is invented nearly two millennia before Japanese mathematician Seki Kowa in 1683 or his German contemporary Gottfried Leibnitz (who is also credited with the invention of differential calculus, separately from but simultaneously with Isaac Newton) found it and use it widely. In chapter eight Methods of rectangular arrays, using a counting board that is mathematically identical to the modern matrix method of solution to solve the simultaneous equation is more widely use. This is also called Gaussian elimination outlined by Carl Friedrich Gauss (1777-1855). Matrices has its important in ancient China and today it is not only solve simultaneous equation, but also for designing the computer games graphics, describing the quantum mechanics of atomic structure, analysing relationships, and even plotting complicated dance steps! Background of Matrices More and larger with amount of numerical data, measurements of one form or another gathered from their lab is confronting the scientists. However the mere collecting and recording data have been collected, data must analyze and interpreted. And here, matrix algebra is useful in both simplifying and promoting much development of many analysis methods but also in organizing computer techniques to execute those methods and present its results. Definition An M x N matrix is a rectangular array of members having m rows and n columns. The number comprising the array are called element of the matrix. The numbers m and n are called dimensions of the matrix. The set of all m x n matrices is denoted by Rm x n. We shall ordinarily denote a matrix by an upper case Latin or Greek letter, whenever possible, an element of a matrix will be denoted by the corresponding lower case Greek letter with two subscripts, the first specifying the row that contains the element and the second the column. ( ) ( ) Thus the 3 x 3 matrix has the form: A3x3 ( ) The matrix is read as A with r rows and c columns has order r x c (read as r by c) or Ar x c And 4 x 3 matrix has the form: ( ) In some applications, notably those involving partitioned matrices, considerable notational simplification can achieved by permitting matrices with one or both its dimensions zero. Such matrices will be said to be void. Row and column matrix The n x 1 matrix A has the form Such matrix is called a column vector which has a single column only, which looks exactly like a member of Rn. We shall not distinguish between n x 1 matrices and n-vectors; they will de denoted by upper or lower case Latin letters as convenience dictates. Example: the 1 x n matrix R has the form R= (à Ã‚ 11, à Ã‚ 12, à ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦ , à Ã‚ 1n). R= (5, 6, 7, à ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦ ,n) Such a matrix will be called a row vector. A well-organized notation is that of denoting matrices by uppercase letters and their elements by the lowercase counterparts with appropriate subscripts. Vectors are denoted by lowercase letters, often from the end of the alphabet, using the prime superscript to distinguish a row vector from a column vector. Thus A is a column vector and R is a row vector, ÃŽÂ » is use for scalar whereby scalar represent a single number such as 2,-4 Equal matrices For two matrices to be equal, every single element in the first matrix must be equal to the corresponding element in the other matrix. So these two matrices are equal: = But these two are not: Of course this means that if two matrices are equal, then they must have the same numbers of rows and columns as each other. So a 33 matrix could never be equal to a 24 matrix, for instance. Also remember that each element must be equal to that element in the other matrix, so its no good if all the values are there but in different places: Combining the ideas of subtraction and equality leads to the definition of zero matrix algebra. For when A=B , then aij =bij And so A B = { aij bij} = { 0 }=0 Which mean in matrix are Square Matrix A square matrix is a matrix which has the same number of rows and columns. An m x n matrix A is said to be a square matrix if m = n Example: number of rows = number of columns. *provided no ambiguity In the sequel the dimensions and properties of a matrix will often be determined by context. As an example of this, the statement that A is of order n carries the implication that A is square. An n-by-n matrix is known as a square matrix of order n. Any two square matrices of the same order can be added and multiplied. A square matrix A is called invertible or non-singular if there exists a matrix B such that AB = I This is equivalent to BA = I Moreover, if B exists, it is unique and is called the inverse matrix of A, denoted Aà ¢Ã‹â€ Ã¢â‚¬â„¢1. The entries Ai,i form the main diagonal of a matrix. The trace, TR(A) of a square matrix A is the sum of its diagonal entries. While, as mentioned above, matrix multiplication is not commutative, the trace of the product of two matrices is independent of the order of the factors: TR (AB) = TR (BA). Also, the trace of a matrix is equal to that of its transpose, i.e. TR(A) = TR(AT). If all entries outside the main diagonal are zero, A is called a diagonal matrix. If only all entries above (below) the main diagonal are zero, A is called a lower triangular matrix (upper triangular matrix, respectively). For example, if n = 3, they look like (Diagonal), (lower) and (upper triangular matrix). Properties of Square Matrix à ¢Ã¢â€š ¬Ã‚ ¢ Any two square matrices of the same order can be added. à ¢Ã¢â€š ¬Ã‚ ¢ Any two square matrices of the same order can be multiplied. à ¢Ã¢â€š ¬Ã‚ ¢ A square matrix A is called invertible or non-singular if there exists a matrix B such that AB = In. Examples for Square Matrix For example: A = is a square matrix of order 3 ÃÆ'- 3. Relations of matrices If R is a relation from X to Y and x1, . . . , xm is an ordering of the elements of X and y1, . . . , yn is an ordering of the elements of Y , the matrix A of R is obtained by defining Aij = 1 if xi R yj and 0 otherwise. Note that the matrix of R depends on the orderings of X and Y. Example: The matrix of the relation R = {(1, a), (3, c), (5, d), (1, b)} From X = {1, 2, 3, 4, 5} to Y = {a, b, c, d, e} relative to the orderings 1, 2, 3, 4, 5 and a, b, c, d, e is Example: We see from the matrix in the first example that the elements (1, a), (3, c), (5, d), (1, b) are in the relation because those entries in the matrix are 1. We also see that the domain is {1, 3, 5} because those rows contain at least one 1, and the range is {a, b, c, d} because those columns contain at least one. Symmetric and anti-symmetric Let R be a relation on a set X, let x1, . . . , xn be an ordering of X, and let A be the matrix of R where the ordering x1, . . . , xn is used for both the rows and columns. Then R is reflexive if and only if the main diagonal of A consists of all 1s (i.e., Aii = 1 for all i). R is symmetric if and only if A is symmetric (i.e., Aij = Aji for all i and j). R is anti-symmetric if and only if for all i = j, Aij and Aji are not both equal to 1. R is transitive if and only if whenever A2 ij is nonzero, Aij is also nonzero. Example: The matrix of the relation R = {(1, 1), (1, 2), (1, 3), (2, 2), (2, 3), (3, 3), (4, 3)} on {1, 2, 3, 4} relative to the ordering 1, 2, 3, 4 is A = We see that R is not reflexive because As main diagonal contains a 0. R is not symmetric because A is not symmetric; for example, A12 = 1, but A21 = 0. R is anti-symmetric because for all i = j, Aij and Aji are not both equal to 1. Reflexive Matrices In functional analysis, reflexive operator is an operator that has enough invariant subspaces to characterize it. The matrices that obey the reflexive rules also called ref matrices. A relation is reflexive if and only if it contains (x,x) for all x in the base set. Nest algebras are examples of reflexive matrices. In dimensions or spaces of matrices, finite dimensions are the matrices of a given size whose nonzero entries lie in an upper-triangular pattern. This 2 by 2 matrices is NOT a reflexive matrices The matrix of the relation which is reflexive is R={(a, a),(b,b),(c,c),(d,d),(b,c),(c,b)}on {a,b,c,d}, relative to the ordering a,b,c,d is Or In generally reflexive matrices are in the case if and only if it contains (x,x) for all x in the base set. Transitive Matrices When we talk about transitive matrices, we have to compare the A(matrix) to the A2(matrix). Whenever the element in the A is nonzero then the element in theA2 have to be nonzero or vice versa to show that the matrices is transitive. For examples of transitive matrices: Then the A2 is Now we can have a look where all the element aij in A and A2 is either both nonzero or both are zero. Another example: Conclusion In conclusion, the matrix we are discussed previous is useful and powerful in the mathematical analysis and collecting data. Besides the simultaneous equations, the characteristic of the matrices are useful in the programming where we putting in array that is a matrix also to store the data. Lastly, the matrices are playing very important role in the computer science and applied mathematics. So we can manage well of matrix, then we can play easy in computer science but the matrix is not easy to understand whereby these few pages of discussion and characteristic just a minor part of matrix. With this mini project, we know more about matrix and if we need to know all about how it uses in the computer science subject, I personally think that it will be difficult as it can be very complicated.

Walkabout :: essays research papers

Walkabout Walkabout is about a young girl, her younger brother, and a bush boy who fight for survival in the Australian desert. James Vance Marshall, the author, shows many problems of survival that the children are faced with, throughout their journey in the Australian desert. Some of the barriers that they are faced with are: language barrier, unfamiliar surroundings and the lack of essential items. Survival in the wilderness can be challenging, however one must be able to overcome these barriers in order to survive. The children in this novel are always faced with a communication problem; do to the Aboriginal not knowing their language and visa versa. The children try to overcome this barrier by using hand gestures, and pointing to things that sound like the word. Communication is the most important asset that they need in order for survival. The children have a difficult time-sharing their thoughts with one another, thus making it very frustrating for all of them to get their thoughts out in the open: 'We don't know what you're saying. But we're lost. We want to go to Adelaide' (Marshall, 45). This quote that Peter says is proving that the two children did not understand what he was saying. Peter asked him a question in return but Peter had to try and use hand expressions in order for the Aboriginal to understand. A language barrier can cause many problems for anyone, however, the children are also faced with another obstacle and that is unfamiliar surroundings. Since the children are unfamiliar with the area and where everything is located in the wild, they do not know how to go about in their journey. With no compass and no map, the children are very puzzled and are lost before they even begin their journey to Adelaide. A compass or a map would have allowed them to know which direction they are heading in; instead they must try and use the sun as a guide. By being in an unfamiliar area the children feel lost and alone: 'Lying beneath the great slab of rock, he looked small and helpless, dwarfed by the immensity of his surroundings'; (Marshall, 18). Since the children are unfamiliar with their environment, knowing where they can locate food becomes a dilemma. Essential items needed for survival are always hard to come by in the desert. Food is the most essential item of them all.

Drivers of Sustainable Supply Chain Management Essay

Drivers of Sustainable Supply Chain Management Introduction                   Sustainability in all operations of a business is a contemporary issue that ensures firms gain competitive advantage. Supply chain management is a discipline dealing with the reorganization of a firm’s extra-supply activities to achieve a competitive edge in the market and take advantage of customer value. It is also concerned with the suppliers attempt to establish and effect supply chains which are both efficient and economical for them. An organization’s supply chain is a multidimensional activity covering most aspects ranging from manufacturing, to goods and services development, and the information systems.The drivers of a sustainable supply chain management can be either internal or external. Internal sustainability drivers include internal business processes while the external are legislation, environmental drivers, customers, and social drivers (Hanuv 35).                   Legal requirements compliance is a fundamental drive in achieving a sustainable supply chain management. It is the starting point because failure to comply to regulations implies that the business is illegal (Cohen 80). Regulatory issues include general environmental laws that may give direction to products disposal and recycling. Compliance to the law enhances the supply chain and hence making it sustainable.                   Financial drivers are also vital for a sustainable supply chain management. Sustainable supply chain management leads to efficiency and effectiveness in business operations that result to good financial performance. This is brought by reversed logistics that result to cost minimization and saving.                   Sustainability is also driven by internal business processes such as offering warrants, product leases, and replacements. These activities enhance effectiveness in production to minimize replacements and hence in the long run a business attains a sustainable supply chain.                   Customers are the most important stakeholders to any business and they greatly drive firms into adopting sustainable supply chain management (Hugos 56). The clients have large number of substitute goods at their disposal, which gives them the driving force to impact the operations a firm. As firms work to accumulate customer’s pressure such as buying from companies with green image, they end up attaining sustainable supply chain management.
