Homework - Assignment Example In investigating measles, epidemiologists embark on various strategic steps that enable them get information. The first step involves preparation for fieldwork which entails getting the right tools, information, support staff and personal arrangements. Information on measles can be obtained from past research on measles (Bystrianyk & Humphries 2013). Additionally, the epidemiologist should delegate roles and responsibilities at this stage of investigations. The second step should be verification that the suspected disease exists. Besides, they ought to establish whether there is an outbreak. Before one decides whether there is an outbreak, they have to determine the number of cases that are expected from an area within a given period. In determining the number of measles cases, for example, one can use the health department surveillance records. The records help determine whether there is an epidemic. Finally, it is important to do a prior investigation before the actual investigatio n. For instance, one can visit some of the children suffering from measles and try to get useful information on the condition. Furthermore, once the data has been collected a measles outbreak should be characterized by place, time and person. This technique is called descriptive epidemiology because it deals with description of what has occurred in the population being studied. This description allows one to evaluate the outbreak on what is recognized about the disease and develop causal hypothesis. These hypotheses can be tested using analytic epidemiology technology. Analytic epidemiology has two components, the cohort and the case-control studies. They help in developing the null and the alternative hypotheses. These hypotheses are later refined after carrying out additional epidemiological study (Bystrianyk & Humphries 2013). The hypothesis is then used in developing and implementing of control measures. Finally, the findings should be presented to bodies such as the

Alternative Drink Industry Analysis Essay Example for Free

Alternative Drink Industry Analysis Essay 1. Do a complete five-forces analysis of competition in the global alternative drink industry, then tell me which of the five competitive forces is strong, weak, and why. Especially in the force of rivalry (one of the 5 forces), you must identify the market size, growth rate, profit margins, what are the main categories in the alternative drink industry, who are the major competitors and their relative sizes, the competition scope, the main competition weapons) 2. Briefly identify 6 to 7 key success factors in the alternative drink industry 3. What are the other economic traits that are outside the industry but still can affect all competitors (for example, overall economy trend, long term innovation, globalization, maturity stage of the industry, relevant legislation, etc. )? Briefly explain how these factors can affect the industry. Notes: 1.   What are the strategically relevant components of the global and U. S. beverage industry macro-environment? How do the economic characteristics of the alternative beverage segment of the industry differ from that of other beverage categories? Explain. The strategically relevant components of the global and U. S. beverage industry macro-environment: †¢ Global beverage companies such as Coca Cola and PepsiCo had relied on such beverages to sustain in volume growth in mature markets where consumers were reducing their consumption of carbonated soft drinks. †¢ Coca-Cola, PepsiCo, and other beverage companies were intent on expanding the market for alternative beverages by introducing energy drinks, sports drinks, and vitamin drinks in more and more emerging international markets. †¢ Beverage producers had made various attempts at increasing the size of the market for alternative beverages by extending existing product lines and developing altogether new products. †¢ Expanding the market for alternatives beverages and increasing sales and market share, beverage producers also were forced to content with criticism from some that energy drinks, energy shots, and relaxation drinks presented health risks for consumers and that some producers’ strategies promoted reckless behavior, the primary concern of most producers of energy drinks, sports drinks, and vitamin-enhanced beverages was how to best improve their competitive standing in the market place. †¢ Rapid growth in the category, coupled with premium prices and high profit margins made alternative beverages an important part of beverage companies’ lineup of brands. The Alternative Beverage Segment Help Companies to Sustain Volume Growth in Mature Markets Where Consumers Were Reducing Their Consumption of Carbonated Soft Drinks. Also the Alternative Beverage Industry Offered 2. What is competition like in the alternative beverage industry? Which of the five competitive forces is strongest? Which is weakest? What competitive forces seem to have the greatest effect on industry attractiveness and the potential profitability of new entrants? Competition from substitutes is substantial. There were many substitutes to alternative beverages such as tea, soft drinks, fruit juices, bottled water and tap water. Even though substitute products had a bigger market share in the US, consumers had tended to buy more alternative beverages. This change in customer preference had weakened the competitive power of substitute beverages. Convenience store, grocery store, and wholesale club buyers had substantial leverage in negotiating pricing and slotting fees with alternative beverage producers because of their large purchases. New brands with low market shares were most vulnerable to buyer leverage since shelf space was limited while top brands such as Red Bull were almost always assured of shelf space. Coca-Cola and PepsiCo were least vulnerable since they offered a wide variety of beverages that convenience stores, grocery stores, and wholesale clubs wished to offer to consumers. As a result of this certain appeal, the two companies’ alternative beverage brands almost always found shelf space in retail stores. The bargaining power and leverage of suppliers was the weakest competitive force. Many suppliers for alternative beverage ingredients and they fight with the others to sell their products. Packaging is readily available from many suppliers and is like a commodity. However, some rare ingredients providers had a moderate amount of leverage in negotiations with energy drink producers. Additionally, the producers of alternative beverages are important customers of suppliers and buy in large quantities. The threat of new brands varies by market maturity of each alternative beverage category. It has low threat for mature categories and moderate to strong in young categories. During the early stages of developing a category, when famous brand leaders had not been established, the threat of entry in alternative beverage categories remained strong. As a result, entrepreneurs launching new beverages with novel formulas or well-developed image campaigns could quickly gain market share among consumers. However, as the category matured, consumer preferences developed and shaped retailers’ purchasing decisions. Once the category had established, its brand leaders, it became much more difficult for new entrants to gain shelf space in convenience stores, supermarkets, and wholesale clubs. Therefore, in 2010, the threat of entry should be lower for all types of alternative beverages except energy shots and relaxation drinks. The competence among sellers of alternative beverage could be considered as the strongest competitive force. Among the sellers of energy drinks and other alternative beverages, competition is so strong and will grow stronger each year. Competition among major brands centers primarily on brand image, an appealing taste, attractive packaging, new product RD, sales promotions and endorsements, and gaining better access to shelf space and strengthening distribution capabilities. As for 2010, there was no evidence of strong price competition in any of the alternative beverage categories, which makes it difficult to argue that competitive rivalry is fierce or brutal. Factors that increase the strength of competitive rivalry included efforts on the part of industry rivals to expand the number and types of alternative beverages in their product lines, low switching costs on the part of consumers, active and aggressive efforts on the part of sellers to establish consumer brand loyalty, and strong emphasis on advertising, sales promotions, and endorsements.

Diabetes Explained Essay example -- Medical Conditions

Special cells in the pancreas produce a hormone called insulin to regulate metabolism. When this hormone is not present glucose cannot enter body cells and blood glucose levels rise. Hyperglycemia may result from this situation. This process is the development of diabetes mellitus. Type 1 diabetes, formerly called juvenile diabetes or insulin dependent diabetes mellitus, has two forms; immune-mediated and idiopathic. Type 1 diabetes accounts for 5-10% of cases in the United States. Research has shown that there is an inherited tendency for developing the disease; it may be triggered by environmental factors (Rosdahl & Kowalski, 2008). It also has an autoimmune component since antibodies to insulin and islet cells are present at the time of diagnosis (p. 1187).

Lord of the Flies- Who Is the Best Leader Essay

In the novel, there is a clear, constant battle for leadership between two of the main characters, Ralph and Jack. The two characters are completely different- as you could say they are the antithesis of one another. In appearance, character, desires (as one wants control through order and civilization and one in self-entertainment). I am going to show how and why Jack Merridew is clearly a better, more appealing leader of the two. First things first, an interesting scene is the one of the elections, at the start of the novel, as the author clearly emphasises the embarrassment and anger Jack feels as he loses the vote. Many judge this negatively, as to pointing out the selfishness and avarice of power Jack demonstrates, but turning the tables, you could also notice Jack’s confidence before the actual elections. This might suggest how Jack is completely sure he can be a better leader, which after turns out to be true towards the end of the novel. Secondly, I would like to point out again how attractive Jack is towards the rest of the boys, as he satisfies completely their primal desires: fun, hunting, messing around. He shows this several times, one of them being: â€Å"he gave a wild whoop and leapt on the pale sand. At once the platform was full of noise and excitement, scrambling, screams and laughter.† This particularly evidences the esteem and admiration the kids feel towards Jack. This is a reason he could be a better leader. Who wants to be a boring, civilized loser, and not a courageous, enthusiastic hunter who likes to kill everything? Which kid would not choose a trusty and confident, skilful leader, over a weak, unstable drag, who can only rely on a fat chatterbox with no benefits of any kind? Therefore this means that I would like to refer again to Ralph’s instability and lack of confidence, as he actually admits in a way to piggy, that Jack is much superior to him, and this is the worst thing a leader can do: not believe in himself. Even more severe is the fact that Ralph almost fears Jack, not only as a menace to his reputation and leadership, but also as a major threat to him. This is shown as Piggy states how Jack detests him, but also detests Ralph, â€Å"maybe because he’s the leader†. He simply says, â€Å"But he’s Jack Merridew!† Another proof of Jack’s power of attention over the kids is after his speech: â€Å"Jack handed the conch and sat. The whole assembly applauded in relief.† He had just insulted most of the little kids, saying they were â€Å"a bunch of cry-babies† which â€Å"never helped doing anything†. But they applauded anyways; by this we can deduce that he is a general referring-point for all, as a brave, imponent figure. But in this case it is important to draw out the fact that Jack just gave spirit and taught a lesson to the littleuns. To conclude the speech, I am going to finish by saying that Jack is certainly the most catchy and enthusiastic leader, and a perfect one, for boys and â€Å"littleuns†. Said, because even the author himself outlines this, by this last quote made by Ralph, which states Jack’s supremacy on him and the boys.

Simple Des

William Stallings Copyright 2006 Supplement to Cryptography and Network Security, Fourth Edition Prentice Hall 2006 ISBN: 0-13-187316-4 http://williamstallings. com/Crypto/Crypto4e. html 8/5/05 Simplified DES, developed by Professor Edward Schaefer of Santa Clara University [SCHA96], is an educational rather than a secure encryption algorithm. It has similar properties and structure to DES with much smaller parameters. The reader might find it useful to work through an example by and while following the discussion in this Appendix. C. 1 Overview Figure C. 1 illustrates the overall structure of the simplified DES, which we will refer to as SDES. The S-DES encryption algorithm takes an 8-bit block of plaintext (example: 10111101) and a 10-bit key as input and produces an 8-bit block of ciphertext as output. The S-DES decryption algorithm takes an 8-bit block of ciphertext and the same 10-bit key used to produce that ciphertext as input and produces the original 8-bit block of plaintext .The encryption algorithm involves five functions: an initial permutation (IP); a complex function labeled fK, which involves both permutation and substitution operations and depends on a key input; a simple permutation function that switches (SW) the two halves of the data; the function fK again; and finally a permutation function that is the inverse of the initial permutation (IP–1). As was mentioned in Chapter 2, the use of multiple stages of permutation and substitution results in a more complex algorithm, which increases the difficulty of cryptanalysis.The function fK takes as input not only the data passing through the encryption algorithm, but also an 8-bit key. The algorithm could have been designed to work with a 16-bit key, consisting of two 8-bit subkeys, one used for each occurrence of fK. Alternatively, a single 8-bit key could have been used, with the same key used twice in the algorithm. A compromise is to use a 10-bit key from which two 8-bit subkeys are gener ated, as depicted in Figure C. 1. In this case, the key is first subjected to a permutation (P10). Then a shift operation is performed.The output of the shift operation then passes through a permutation function that produces an 8-bit output (P8) for the first subkey (K1 ). The output of the shift operation also feeds into another shift and another instance of P8 to produce the second subkey (K 2 ). We can concisely express the encryption algorithm as a composition1 of functions: which can also be written as: IP-1 o fK2 o SW o fK1 o IP ((( ciphertext = IP-1 fK 2 SW fK1 (IP(plaintext )) where ( K1 = P8 Shift (P10(key )) ! ( ( ))) ) K2 = P8 Shift Shift( P10( key)) )) Decryption is also shown in Figure C. and is essentially the reverse of encryption: ((( plaintext = IP-1 fK1 SW fK 2 (IP(ciphertext )) 1 ))) Definition:! f f and g are two functions, then the function F with the equation y = F(x) = I g[f(x)] is called the composition of f and g and is denoted as F = g o f . C-2 8/5/05 We now examine the elements of S-DES in more detail. C. 2 S-DES Key Generation S-DES depends on the use of a 10-bit key shared between sender and receiver. From this key, two 8-bit subkeys are produced for use in particular stages of the encryption and decryption algorithm. Figure C. 2 depicts the stages followed to produce the subkeys.First, permute the key in the following fashion. Let the 10-bit key be designated as (k1 , k2 , k3 , k4 , k5 , k6 , k7 , k8 , k9 , k10). Then the permutation P10 is defined as: P10(k1 , k2 , k3 , k4 , k5 , k6 , k7 , k8 , k9 , k10) = (k3 , k5 , k2 , k7 , k4 , k10, k1 , k9 , k8 , k6 ) P10 can be concisely defined by the display: 3 5 2 7 P10 4 10 1 9 8 6 This table is read from left to right; each position in the table gives the identity of the input bit that produces the output bit in that position. So the first output bit is bit 3 of the input; the second output bit is bit 5 of the input, and so on.For example, the key (1010000010) is permuted to (1000001 100). Next, perform a circular left shift (LS-1), or rotation, separately on the first five bits and the second five bits. In our example, the result is (00001 11000). Next we apply P8, which picks out and permutes 8 of the 10 bits according to the following rule: P8 6 3 7 4 8 5 10 9 The result is subkey 1 (K1 ). In our example, this yields (10100100) We then go back to the pair of 5-bit strings produced by the two LS-1 functions and perform a circular left shift of 2 bit positions on each string. In our example, the value (00001 11000) becomes (00100 00011).Finally, P8 is applied again to produce K2 . In our example, the result is (01000011). C. 3 S-DES Encryption Figure C. 3 shows the S-DES encryption algorithm in greater detail. As was mentioned, encryption involves the sequential application of five functions. We examine each of these. Initial and Final Permutations The input to the algorithm is an 8-bit block of plaintext, which we first permute using the IP function: IP 2 6 3 1 4 8 5 7 This retains all 8 bits of the plaintext but mixes them up. At the end of the algorithm, the inverse permutation is used: C-3 8/5/05 1 3 IP–1 57 2 8 6 It is easy to show by example that the second permutation is indeed the reverse of the first; that is, IP–1(IP(X)) = X. The Function fK The most complex component of S-DES is the function fK, which consists of a combination of permutation and substitution functions.The functions can be expressed as follows. Let L and R be the leftmost 4 bits and rightmost 4 bits of the 8-bit input to fK, and let F be a mapping (not necessarily one to one) from 4-bit strings to 4-bit strings. Then we let fK(L, R) = (L ! F(R, SK), R) where SK is a subkey and ! s the bit-by-bit exclusive-OR function. For example, suppose the output of the IP stage in Figure C. 3 is (10111101) and F(1101, SK) = (1110) for some key SK. Then fK(10111101) = (01011101) because (1011) ! (1110) = (0101). We now describe the mapping F. The input is a 4-bi t number (n 1 n2 n3 n4 ). The first operation is an expansion/permutation operation: 4 1 2 E/P 32 3 4 1 For what follows, it is clearer to depict the result in this fashion: n4 n2 n1 n3 n2 n4 n3 n1 The 8-bit subkey K1 = (k11, k12, k13, k14, k15, k16, k17, k18) is added to this value using exclusiveOR: n4 ! 11 n2 ! k15 n1 ! k12 n3 ! k16 n2 ! k13 n4 ! k17 n3 ! k14 n1 ! k18 p0,1 p1,1 p0,2 p1,2 p0,3 p1,3 Let us rename these 8 bits: p0,0 p1,0 The first 4 bits (first row of the preceding matrix) are fed into the S-box S0 to produce a 2bit output, and the remaining 4 bits (second row) are fed into S1 to produce another 2-bit output. These two boxes are defined as follows: C-4 8/5/05 0 S0 = 1 2 3 0 â€Å"1 $3 $0 $3 # 1 0 2 2 1 2 3 1 1 3 3 2% 0†² 3†² 2†² ; 0 S1 = 1 2 3 0 â€Å"0 $2 $3 $2 # 1 1 0 0 1 23 2 3% 1 3†² 1 0†² 0 3†² & The S-boxes operate as follows.The first and fourth input bits are treated as a 2-bit number that specify a row of the S-box, and the s econd and third input bits specify a column of the Sbox. The entry in that row and column, in base 2, is the 2-bit output. For example, if (p0,0p0,3) = ! (00) and (p0,1p0,2) = (10), then the output is from row 0, column 2 of S0, which is 3, or (11) in binary. Similarly, (p1,0p1,3) and (p1,1p1,2) are used to index into a row and column of S1 to produce an additional 2 bits. Next, the 4 bits produced by S0 and S1 undergo a further permutation as follows: P4 2 4 3 1 The output of P4 is the output of the function F.The Switch Function The function fK only alters the leftmost 4 bits of the input. The switch function (SW) interchanges the left and right 4 bits so that the second instance of f K operates on a different 4 bits. In this second instance, the E/P, S0, S1, and P4 functions are the same. The key input is K2 . C. 4 Analysis of Simplified DES A brute-force attack on simplified DES is certainly feasible. With a 10-bit key, there are only 2 10 = 1024 possibilities. Given a ciphertex t, an attacker can try each possibility and analyze the result to determine if it is reasonable plaintext. What about cryptanalysis?Let us consider a known plaintext attack in which a single plaintext (p1 , p2 , p3 , p4 , p5 , p6 , p7 , p8 ) and its ciphertext output (c1 , c2 , c3 , c4 , c5 , c6 , c7 , c8 ) are known and the key (k1 , k2 , k3 , k4 , k5 , k6 , k7 , k8 , k9 , k10) is unknown. Then each ci is a polynomial function gi of the pj ‘s and kj ‘s. We can therefore express the encryption algorithm as 8 nonlinear equations in 10 unknowns. There are a number of possible solutions, but each of these could be calculated and then analyzed. Each of the permutations and additions in the algorithm is a linear mapping.The nonlinearity comes from the S-boxes. It is useful to write down the equations for these boxes. For clarity, rename (p0,0, p0,1,p0,2, p0,3) = (a, b, c, d) and (p1,0, p1,1,p1,2, p1,3) = (w, x, y, z), and let the 4-bit output be (q, r , s, t) Then the operati on of the S0 is defined by the following equations: q = abcd + ab + ac + b + d r = abcd + abd + ab + ac + ad + a + c + 1 where all additions are modulo 2. Similar equations define S1. Alternating linear maps with these nonlinear maps results in very complex polynomial expressions for the ciphertext bits, making cryptanalysis difficult.To visualize the scale of the problem, note that a polynomial equation in 10 unknowns in binary arithmetic can have 210 possible terms. On average, we might therefore C-5 8/5/05 expect each of the 8 equations to have 29 terms. The interested reader might try to find these equations with a symbolic processor. Either the reader or the software will give up before much progress is made. C. 5 Relationship to DES DES operates on 64-bit blocks of input. The encryption scheme can be defined as: IP-1 o fK16 o SW o fK15 o SW oL o SW o f K1 o IPA 56-bit key is used, from which sixteen 48-bit subkeys are calculated. There is an initial permutation of 64 bits foll owed by a sequence of shifts and permutations of 48 bits. Within the encryption algorithm, instead of F acting on 4 bits (n1 n2 n3 n4 ), it acts on 32 bits (n1 †¦n32). After the initial expansion/permutation, the output of 48 bits can be diagrammed as: n32 n4 †¢ †¢ †¢ n28 n1 n5 n29 n2 n6 †¢ †¢ †¢ n30 n3 n7 n4 n8 n31 n32 n5 n9 †¢ †¢ †¢ n1 This matrix is added (exclusive-OR) to a 48-bit subkey. There are 8 rows, corresponding to 8 S-boxes. Each S-box has 4 rows and 16 columns.The first and last bit of a row of the preceding matrix picks out a row of an S-box, and the middle 4 bits pick out a column.

Make Use of These Connecting Words and Phrase All Writers Apply

Make Use of These Connecting Words and Phrase All Writers Apply Here is a list of words and phrases that are used to connect the sentences, the ideas and thoughts in any type of essays. Although, to many students, a writing assignment may seem like a very cruel form of torture, writing, in reality, can serve as a very useful tool in developing one’s critical thinking skills, and can help build one’s expertise in using their language. Also, writing enhances one’s ability to communicate effectively, which is a critical and much-needed skill in the workplace. It is a skill that will, to put it bluntly, help people get what they want in life and in their career.  For example, the effective communicator accesses the job interview and lands a good job over the person who isn’t an effective communicator. The same applies to educational writing. When it comes to written communication (especially when writing the major essay types: argumentative essay, or persuasive essay, cause and effect essay, compare and contrast essay or  expository essay), the better the student conveys a point, makes a solid argument, and presents a well-detailed treatise on a certain subject, the more likely they will obtain a high grade on the writing assignment. This is usually accomplished through the use of connection words and phrases. Regardless of the kind of an essay, a student is assigned to write, a working knowledge of connection words and phrases (as well as how to correctly incorporate them into a written assignment) is always advantageous. These can help support a claim, make an argument, help to defend one’s reasoning and especially illustrate cause and effect; they help provide a thorough explanation and can certainly persuade the reader to believe or agree with an argument. Connection/connecting or linking verbs and phrases can illustrate objection or a rebuttal of something (with words like however, but, and on the contrary); they can provide an illustration (for example, for instance), can incorporate transitional phrases for enumeration (first, secondly, next, finally, lastly), and can demonstrate consequence (therefore, consequently, as a result). List of Connecting Words and Phrases Before looking through the list of connecting words and phrases, you may read another article on the similar topic: The Importance of the Transition Words and Phrases Some of these phrases and words begin a sentence, while others are used to connect two separate thoughts – either with the use of a semicolon or well-placed comma, and are therefore inserted in the middle of a sentence. The purpose Connecting words and phrases Example To indicate a contrast in comparison; however; on the contrary; rather; alternatively; however; though; nevertheless; notwithstanding; in spite of this; although; similarly; conversely Writing well is a product of hard work, education, and extensive reading; however, some people are natural-born storytellers. To provide an illustration for example; that is to say; in other words; namely; such as; including; chiefly; mainly; most importantly Prohibition was a terrible, dreadful failure, mainly because it did nothing but make a lot of criminals – namely bootleggers – filthy rich. To extend a point similarly; equally; likewise, furthermore; also; indeed; above all; as well; in addition It has been said that writer Ernest Hemingway had no other interests beyond violence, and sports; and, indeed, he published several books that confirm this observation To demonstrate cause and effect, or a conclusion between two notions therefore; thus; hence; as a result; consequently; this suggests that; in short; this implies; in all There have been recent discoveries that amoebas do not leave behind a carbon footprint; therefore it is virtually impossible to determine exactly how long they have been on Earth. Transitional, to indicate the next step first of all; next; secondly; to begin with; first and foremost; then; finally; ultimately; lastly First of all, Christopher Columbus should not be considered a hero to Americans. Secondly, Columbus was not even the first explorer to discover the Americans. To summarize overall; in sum; to sum it up; in conclusion In conclusion, this essay examined two entirely different – yet effective – methods of teaching math to fifth-graders. Connecting words and phrases are very important while writing an academic paper.

Jane Eyre by Charlotte Bronte

Jane Eyre by Charlotte Bronte Free Online Research Papers Jane Eyre, a novel about an English woman’s fights told through the writing of Charlotte Brontà «, has filled its audience with thoughts of hope, love, and deception for many years. These thoughts surround people, not just women, everyday, as if an endless cycle from birth to death. As men and women fall further into this spiral of life they begin to find their true beings along with the qualities of others. This spiral then turns into a web of conflicts as the passenger of life proceeds and often these conflicts are caused by those sought out to be guides through the journey of life but merely are spiders building a magnificent web to catch its prey. In Jane Eyre, Brontà « uses the literary elements of plot and character to convey the theme that a person often falls in love with a manipulator because she has little experiences of other forms of love and as a result she has to establish her own integrity. Brontà « uses the character element of opinions to show how some people often form conclusions about others and express them in their thoughts as either cruel or friendly. Since Brontà « bases Jane Eyre as story told through a young lady the reader is allowed to experience her thoughts and reactions to those around her who make her very personality. As Jane is in her youth she develops these notions about her own family yelling at her cousin John saying, â€Å"You are like a murdereryou are like a slave-driver- you are like the Roman Emperors.† (p. 8) Not only showing that Jane has the intellectual maturity much greater than that of a normal ten-year-old but also that she finds John cruel and sees him becoming a bad man when he grows up. Due to Mrs. Reed’s lack of discipline John did grow as his cousin perceived causing his own demise and the relief of Jane for her cousin no longer could torment those lesser than himself. â€Å"Mr. Rochester continued blind for the f irst two years of our union: perhaps it was that circumstance that drew us so very near – that knit us so very close: for I was then his vision, as I am still his right hand. Literally, I was the apple of his eye.† (p.578) Jane expresses her grief over Rochester’s injuries but emphasizes her constant love as everything that he has lost. Rochester appears completely opposite from the first time they met; he’s helpless just as Jane was when they first met and it is her influence which provokes him to her. All of Jane’s, along with the other characters, opinions cause changes in positions from being blind to walking for the blind, or from being led to doing the leading. Brontà « uses the character element of appearance to show that corrupting people often influence others by their mere charismatic look. This is shown through the description of Edward Rochester as he first meets Jane and begins his moral capture of Jane. â€Å"He had a dark face, with stern features and a heavy brow; his eyes and gathered eyebrows looked ireful and thwarted, just now; he was past youth’ but had not reached middle age; perhaps he might be thirty-five. I felt no fear of him and but little shyness.† (p.142) These words spoken by Jane clearly show that by a slight glance, without even knowing a person, a conclusion is made; Jane’s decision here is that Rochester is her protection, her scapegoat out of her life of solitude. She also mentions how she doesn’t fear him, allowing the audience to sense his commanding aura as if it were a protective wall giving this young shy lady the ability to comfort herself in this strange new acquaintance. Jane continues by saying, â€Å"Had he been a handsome, heroic-looking young gentleman, I should not have dared to stand thus questioning him against his will and offering my services unwillingly.† (p.142) This is an example of the theory that women choose to be with men that they feel will ensure them with protection and strong healthy children. Every woman has her vision of that prince charming that will ride in on his steed and woe her off her feet and give her that magical kiss to free her from all previous burdens that she may have had. Jane seems to take notice to Rochester’s age but in change is intrigued by his masculinity, which she experienced in short at Lowood School with Mr. Brocklehurst. All it took was an accidental meeting between Jane and her employer to begin the cycle of love that would eventually overtake then empower a meek woman inexperienced in the art for which she has been a pawn of. Brontà « uses the stylistic character element of speech to induce a thought that the words of some admirable people often influence others and sometimes can even be heard from them. Through the mentoring of Rochester and St. John does the reader see two different men, both in some way bringing them closer to Jane turning her into what they have both become. â€Å"Brontà «Ã¢â‚¬â„¢s authorial strategy is to balance one kind of temptation with its obverse: if Rochester is all romantic passion, urging her to succumb to emotional excess, St. John Rivers is all Christian ambition, urging her to attempt a spiritual asceticism of which she knows herself incapable.† (Joyce Carol Oates) Oates relates these men to their backgrounds and how they both tempt Jane with their own strategies of moral tactics. Because Jane was raised in a strict boarding school it becomes apparent why she can be attracted to St. John and his Christian-like ways, but her inexperience with love due to Lowood al ways causes her to be attracted to Rochester. Rochester ask Jane, â€Å"am I cruel in my love† (p.365) This question provokes Jane to decide whether she truly knows love or not. A young woman from a boarding school having to resolve her love for this man causes a type of confusion in Jane and she is left with the mere thought that she must love this man. Rochester furthermore entangles Jane when he tells her, â€Å"Be not far from me, for trouble is near: there is none to help.†(p.377) Rochester gives her assurance that he is her protection and that she has somewhere to go when trouble rises. This is better for Rochester because he knows that this is the first and only secure place that she has known of and if trouble arises she will come to him for help as her guide and mentor. Men realize that they can input their vibes into young woman and often do this in order to either please their own lustful wants or fulfill their needs. Brontà « uses the plot element of general events to show that as corrupters advance with those easily manipulated they change, not only themselves, but also those they try to manipulate. Jane initially meets Mr. Rochester as a governess to Ad?le, but their conversations lead to mysterious times of revealing each others past so Rochester decided to dress as a fortune-teller. Fortune-tellers are seen as mysterious and able to unlock truths, which apparently Rochester attempts to do; find the truths about Jane’s emotions, especially anything about him. When Rochester reveals his identity Jane realizes the traps she’s fallen in and the entrapment that Rochester causes for his own wants to know about Jane. As Rochester remain handicapped before their marriage he ask Jane if she would marry a, â€Å"crippled man, twenty years older than [her], whom [she] will have to wait on.† (p.570) This particular event is Jane’s deciding moment where she picks to stay with the man that she supposedly loves or to go out and adventure like the one she somewhat had love for in St. John. Jane chooses to stay with Rochester and start a beautiful life together as she had always planned to do. As she is married to Rochester Jane sends Ad?le off to school in order to get rid of her French heritage. This is exactly what Jane didn’t want to happen when Blanche Ingram was supposedly going to marry Rochester. The reader can find this her ultimate change from an innocent woman to the one manipulating others in place of her crippled husband. When Jane finally ends as a manipulator the reader sees that corruption can be passed and characters undergo changes due the actions of those around them. Brontà « uses the plot element of a specific event to reveal that some people have dark past which cause them to seem mysterious and sometimes very intriguing, this is seen in the discussion between Jane and Rochester for the fir time in the house. Rochester begins his insightful conversation by telling Mrs. Fairfax that Jane is the reason for his sprained ankle. The reader immediately catches this as distaste for Jane and sees Rochester as a resentful man full of hatred. The men Jane had known in her life were all full of hate; from little John Reed to the schoolmaster, Mr. Brocklehurst. Rochester then brought up her former schoolmaster, asking about conditions at Lowood and what all she had the privilege to learn while attending. Rochester becomes more involved asking these type questions and allows Jane to find her security in him for he is her employer and must know her background if she wishes to teach his Ad?le. The thought of Lowood has significance because of the low, which symbolizes her lowest point of existence and if she is able to just talk about it he will know where it is that haunts her most. They end with comments on Jane’s artwork and how imaginative it is. This partially is due to her over-imaginative youth with books and troubling family. Rochester hit every point of the childhood Jane wanted to forget so that he would know a little about the new lady sleeping in his home. In order for someone to come accustomed to their surroundings they must make peace with their past; Rochester guides Jane into accepting her past. Brontà « uses the plot element of digression to express that individual questioning and talking between two people can provoke one, such as Jane when she gets her fortune told, to express all their feelings and find themselves in the process. Rochester, imposing as a gypsy, begins by asking Jane about now she is feeling and why she’s not nervous. This type of introduction gives Jane a sense of self-determination knowing that she feels fine and controls her own destiny no matter what the fortune-teller may say. This type of confidence is found through self-examination and allows its seekers the will to continue no matter what the outcome may be. Though Jane replied to the fortune-teller as being fine the fortune-teller told her â€Å"You are cold, because you are alone; no contact strikes the fire from you that is in you. You are sick, because the best of feelings, the highest and the sweetest given to man, keeps far away from you. You are silly, because, suffer as you may, y ou will not beckon it to approach, nor will you stir one step to meet it where it waits for you.† (p.248) Rochester notices her fault and clearly points them out to her. Allowing a person to hear their own faults causes them to examine whether or not these accusations are true or not. In Jane’s case Rochester pinned out Jane’s faults and he’s doing his part to help her become more like him instead of being a shy, little, shrewd Quaker. The fortune-teller finally mentions Jane’s love for Rochester, but unknown to Jane the fortune-teller is Edward Fairfax Rochester. Jane hints toward this love but has clearly been manipulated by Rochester into his entanglement of love, which Blanche was thought to be in the center of. The main point of Rochester’s deception is to encourage Jane to except her love and express is to someone other than Rochester and to feel love for the first time if at all possible. As Brontà «Ã¢â‚¬â„¢s novel is read over through the generations, the theme that a person can be manipulated into love and often times has to find her own integrity is passed on. By using many different elements of plot and characters she creates a novel forever found to be part of American Literature and English History.

Why the Sun Looks Yellow When Its Really Not

Why the Sun Looks Yellow When Its Really Not If you ask a random person to tell you what color the sun is, chances are he will look at you like youre an idiot and tell you the sun is yellow. Would you be surprised to learn the sun is not yellow? Its actually white. If you were to view the sun from the International Space Station or the moon, youd see its true color. Check space photos online. See the true color of the sun? The reason the sun appears yellow during the day from Earth, or orange to red at sunrise and sunset, is because we view our favorite star through the filter of the atmosphere. This is one of the tricky ways in which light and our eyes change the way we perceive colors, as is the case with the so-called impossible colors. The True Color of the Sun If you view sunlight through a prism, you can see the entire range of wavelengths of light. Another example of the visible portion of the solar spectrum is seen in the rainbow. Sunlight isnt a single color of light, but a combination of the emission spectra of all the elements in the star. All of the wavelengths combine to form white light, which is the net color of the sun. The sun emits different amounts of various wavelengths. If you measure them, the peak output in the visible range is actually in the green portion of the spectrum (not yellow). However, visible light isnt the only radiation emitted by the sun. Theres also  blackbody radiation.  The average of the solar spectrum is a color, which indicates the temperature of the sun and other stars. Our sun averages about 5,800 Kelvin, which appears nearly white. Out of the brightest stars in the sky, Rigel appears blue and has a temperature exceeding 100,000K, while Betelguese has a cooler temperature of 35,00K and appears red. How the Atmosphere Affects Solar Color The atmosphere changes the apparent color of the sun by scattering light. The effect is called Rayleigh scattering. As violet and blue light gets scattered away, the average visible wavelength or color of the sun shifts toward red, but the light isnt entirely lost. The scattering of short wavelengths of light by molecules in the atmosphere is what gives the sky its blue color. When viewed through the thicker layer of atmosphere at sunrise and sunset, the sun appears more orange or red. When viewed through the thinnest layer of air at midday, the sun appears closest to its true color, yet still has a yellow tint. Smoke and smog also scatter light and can make the sun appear more orange or red (less blue).  The same effect also makes the moon appear more orange or red when it is close to the horizon, but more yellow or white when it is high in the sky. Why Pictures of the Sun Look Yellow If you view a NASA photo of the sun, or a photo taken from any telescope, youre usually viewing a false color image. Often, the color that is chosen for the image is yellow because its familiar. Sometimes photos taken through green filters are left as-is because the human eye is most sensitive to green light and can readily distinguish detail. If you use a neutral density filter to observe the sun from Earth, either as a protective filter for a telescope or so you can observe a total solar eclipse, the sun will appear yellow because youre reducing the amount of light that reaches your eyes, but not changing the wavelength. Yet, if you used that same filter in space and didnt correct the image to make it prettier, youd see a white sun.

Pleaes .Requires.Overview.Paraphrase..rewrttin Essay

Pleaes .Requires.Overview.Paraphrase..rewrttin - Essay Example Medical imaging involving ionizing radiation uses x-rays and gamma rays. As the ionizing radiation passes through the body, it is differentially absorbed by tissues of greater thickness, causing ionization of tissue atoms making them chemically reactive and potentially capable of cell damage (Yale 2011). This raises concern over the frequent use of ionising radiation in medical imaging, and the associated risks to human health. Exposure to ionizing radiation is of concern because evidence has linked exposure to low-level ionizing radiation at doses used in medical imaging to the development of cancer. The National Academy of Sciences’ National Research Council comprehensively reviewed biological and epidemiological data related to health risks from exposure to ionizing radiation, recently published as the Biological Effects of Ionizing Radiation (BEIR) VII Phase 2 report. The epidemiologic data described atomic bomb survivors, populations who lived near nuclear facilities duri ng accidental releases of radioactive materials such as Chernobyl, workers with occupational exposures, and populations who received exposures from diagnostic and therapeutic medical studies. Radiation doses associated with commonly used CT examinations resemble doses received by individuals in whom an increased risk of cancer was documented. For example, an increased risk of cancer has been identified among long-term survivors of the Hiroshima and Nagasaki atomic bombs, who received exposures of 10 to 100 milli-sieverts (mSv). A single CT scan can deliver an equivalent radiation exposure, and patients may receive multiple CT scans over time. (Smith-Bindman et al 2009) Risks involved in the use of Ionizing radiation Since the finding of the first solid tumour that resulted from the effects of ionizing radiation, protection from ionizing radiation used in medical procedures has become a vital issue, particularly in view of the dramatic increase in the number medical procedures involv ing its use (Davros et al 2007). Because of the public uproar over radiation protection, an International Commission for Radiation Protection was established in 1928. "The International Commission on Radiological Protection (ICRP) estimates that the average person has an approximately 4-5% increased relative risk of fatal cancer after a whole-body dose of 1 Sv. However, other studies on multiple cohorts of radiation workers have largely failed to establish statistically significant cancer risks. When multiple occupational cohorts were combined and evaluated in a somewhat systematic way, a combined excess relative risk of cancer death of just less than 1% was estimated" (Cardis et al 2005). During the 1950s and 1960s, there were an increasing number of indicators that ionizing radiation was dangerous to humans. Experimentation using X-rays on animals, particularly rats, have linked ionizing radiation exposure to impending death, even at low levels. It has been proved that high and mo re frequent doses of radiation pose greater risks to the patient, causing, for example, skin erythema and other kinds of irritations (Egbe et al 2009). Other side-effects of ionizing radiation include dizziness, nausea, and light headedness. Risks associated with radiation exposure in hepato-biliary scans are quite high. In a study by McCollough et al (2009) it was found that in many cases, the onset of cancer was linked to the area frequently exposed to x-rays. Other studies suggest that

The Significance of Lyrics in a Song Essay Example | Topics and Well Written Essays - 750 words

The Significance of Lyrics in a Song - Essay Example The significance of words in a song is very well known. Indeed words are the building blocks of the songs. Any song writer will know the relevance of the words for its composition. It is the words that cause a stir in the minds of the song composer and as a result of this kind of effect; the song takes its birth. The song writer often uses special techniques so as to blend the words, to make the song quite unique and at the same time inspire the listeners. Indeed this could be considered as the real history behind the production of the songs. It is through this process by which the great song composers have been able to produce the greatest songs, ever known in the history of mankind. The power of the words is so much that, it can make the mind of the composer as well as the listener to get motivated and boosted up and take oneself to an elevated magical platform, where the inner meaning of the words can be visualized and realized. For this reason they are extremely choosy about the words and feel that a song’s whole power lies in it. ... Thus based on the song written the music is composed in such a way that, the tune fits very well with the words or lyrics and gives a unique experience to the listener. (www.scribd.com ) This technique is most commonly used in the case of popular song creation and very well seen in the case of the national anthem, where the tunes and the melody composed is made to fit with the text that is being written. It is always seen that in a majority of cases the music composers are not expert song writers due to which, they rely heavily on the lyrics and the poems written by others. This has been the common practice among the music composers down the ages and belonging to different nationalities. Almost in all the countries like England, Germany and America this system has been practiced. Examples are Franz Schubert who had been a very well known German music composer, very well relied on the poetry of many famous German poets like Heinrich Heine and many others. Aaron Copland the American mu sic composer was very much attracted to the poetry, that was written by Emily Dickinson and almost all the major musical works were based on the verses of this poet. (www.poets.org ) Thus history has been filled with several such cases which very well prove that, the greatest music composers the world over have been very much inspired by the verses of poetry written by the great poets. They get inspiration from them and tune their music based on the settings and text of the poems. It has been seen that in the modern day, it is not only the traditional music composers who tune their songs based on the poetry works but also the various rock bands and pop bands also compose the music, taking direct inspiration from the poetic

Kangxi-Emperor and the Taiping Rebellion Essay Example | Topics and Well Written Essays - 500 words

Kangxi-Emperor and the Taiping Rebellion - Essay Example Kangxi was one of the best Emperors in those times because he never mobilized people into fighting. He gave out rules that were friendly to people and rules that would easily be followed without questions. Being a man with a Family, farming would be an important thing so as to provide food for the family, Kangxi told people to respect farming so as to have adequate food and clothing. He encouraged people to love schools and academics as that was one way of gaining knowledge and honoring the scholar. Hong Xiuquan after failing his second exam attempt, he gave up and continued to protestant missionaries. He never encouraged people to love education or anything related to it (Foster 158). Being a family man and living during the Hong Xiuquan times, it would be hard to encourage a person’s children into a school considering the War that was everywhere. The Army, which anyone would expect to bring peace, was the leader in destroying the Cities. The Taiping beliefs followed the Ten Commandments similar as the ones found in the bible but they separated men and women from living together. Women were given more power and even married couples lived in quarters segregated by sex. Following the Commandments was a better idea with the Taiping rules but separating married couples was not a good idea. People who are married are supposed to live happily together but the Taiping rules would never allow that (Foster 160). The Taiping rules were things that you should never do but there were no things to be done.

East Asian Art History - Essay Example Modern society has embraced the art of mask. Research has been done on it and a wide range of uses found. China has become a hub of this art. Masks are a cultural event celebrated all over China nowadays (Scott, 2009). To some Chinese communities these masks have become a form of god. They are worshipped because of their uniqueness and awesome appearance. They are seen as a means of communication between people and gods. They have been used as a means to seek for blessings from gods. They are also used to protect people from evil spirits. They are believed to be a form of charm in many Chinese communities. They symbolize holiness and godliness. In modern days, there are many cultural festivals involving masks that are held (Desai, 2007). People wearing masks are seen dancing and celebrating along the streets. The first mask in this art is called ‘Funerary Mask of a Young Woman’. This mask is from Liao Dynasty (907 – 1125), Northern China. Quran community founded Liao Dynasty. This community was the minority in Chinese population around 10th century in North of China (Scott, 2009). The majority of Chinese population was called the Han Chinese.

The film Little Big Man Essay Example | Topics and Well Written Essays - 750 words

The film Little Big Man - Essay Example These include the contrary warrior, the two-spirited person and the grandfather. These are entities of the Cheyenne that occupy their ordinary life. In portrayal of the two-spirited warrior, the sculpture emanates from the view of the little big man. It is vital to note that the young crab grows to become a successful warrior in the Cheyenne army. The younger bear, who is the contrary warrior, creates enmity with the little big man (Grant 98). The fundamental portrayal of the contrary warrior concerns the fact that nature stems from the fact that they are rebellious spirits. Their rebellion seems to stem from an injustice that they witness around them. This injustice may have trivial or concrete reasons. In the younger bear’s case, he seems to be envious of the little big man’s success. In turn, he strives to convince his society of his inner prowess. This does not bear success, in the short run, and he becomes frantic at the same. It comes as a further blow when the little big man saves him from a Pawnee warrior. The contrary warrior comes across as a superb portrayal of prowess in war and life skills. In this sense, the contrary warrior would walk on his hands around the camps. In addition, he would be able of extraordinary skills of riding the horse backwards. He would be able of turning their arches for backward shooting of arrows. Whenever he could come across a stream, he would lift his moccasin and hop through the water. His rebellion focused on doing the opposite things during wars. This would be both beneficial and counterproductive to wars. In spite of the contrary warrior’s struggles at seeking recognition, he is the same. This proves the same when he saves the little big man from Custer’s pistol. The grandfather shares a positive portrayal in the film story. He surfaces in the same when he saves the little big man and Caroline from the wild. It is vital to note that the Pawnee warriors are a dangerous group

What is the relation between the divided line and the allegory of the Essay

What is the relation between the divided line and the allegory of the cave from Books 6 and 7 of the Republic Do you find this to be an accurate representation of the process of learning - Essay Example According to Plato, the bottom two; imagination and belief, can be perceived as simple opinions and are different from one person to another (Baird 500-520). The two are found in the physical world and are discoverable through senses that can be mistaken making the truth that is associated with these two vary form one person to another. The next two, which are understanding and reason, are in existence to seek truths in the meta-physical world making them collectively true. The type of truth associated with understanding included that of mathematics, maxims along with definitions, and even though they are artificial, they are questioned. The best way to achieve truth of knowledge is through reason which actively questions issues in the environment. In Plato’s view, reasoning brings understanding of the forms and forms possess the ultimate truth. Plato implies that goodness and love are products of reason but this love is not identical to the kind of love that is perceived in the present day. Love as explained by Plato is the desire for something that is not possessed, and this motivates people to get what they do not have. The allegory of the cave explains the route one must take in order to achieve this knowledge and how individuals are bound in the cave of imagination where the shadows that are on the walls are the truths. The people who create the shadows are those in positions of power who have the belief that they are conversant with the truth and attempt to utilise it in corrupting the masses into giving them more power. Fire stands for an imperfect good while love represents a self-good that is supposed to bring more power to them. An individual inside the cave should be able to see further than the shadows and turn in the direction of the fire while identifying that the objects seen in the hands of the puppeteer may seem true but are not actually true. When a person leaves the cave, he will be blinded by the

Weimar Republic Essay Example for Free

Weimar Republic Essay The WR began after WWII the Treaty of Versailles was signed by the Germans and forced to have a democracy rather than a monarchy. The Government from the start was full of problems with its economy, social and political areas, what made it worse was the Great Depression in 1929. The WR was vulnerable to a number of attacks from many different areas including the Nazi party and its leader Hitler. It was attacked for its constitution, unfamiliar structure and its inability to quickly restore Germany. The Nazis appealed to their audience with its foreign and domestic policies, its authoritarian rule, propaganda radical policies and Hitler’s Charisma. After many problems challenging the WR, it collapsed in 1933 and the Nazis thrived from this. The Treaty of Versailles was signed in 1919 by the WR and was a huge hit on Germany and its people. The treaty was seen by Germans as the loss of Germany’s image of a great nation with a powerful military. As a result the WR was often called the ‘November Criminals’ and accused them of the idea of the ‘Dolchstoss(stab in the back)†. Most of this was due to the fact that the allies forced Germany to pay the harsh terms of the war reparations amounting to 60 billion dollars. The WR’s obvious economic problems and the public’s view on them made it look like it was inevitably going to collapse. Hitler used the idea of ‘November Criminals’ and the Treaty of Versailles as propaganda to show the shame that the WR brought on Germany. In one video it is shows Hitler ripping the Treaty of Versailles in front of the crowd causing a frenzy of high German spirit. The WR as a democratic system was very new to the Germans as they were used to an authoritative monarchy. Germans had a â€Å"rich monarchical tradition that had substantial success under authoritative moulds of government† which made it difficult to accept the democracy. Another problem faced by the WR was that the constitution clause of the Reichstag being that of proportional representation which meant a political leader for every party. This was troublesome as it was difficult to find a majority because of many conflicting perspectives. The fire in the parliamentary building in 1933, which some believe the Nazis started, was a situation used by Hitler to show the failure of democracy. He also took advantage of Article 48. In years later when Hitler has much power he completely contrasts the WR policies by being a single powerful dictator and making policies to get rid of all opposition by any means as shown in the ‘Night of the long knives†. In 1924 to 1929 Germany was surprisingly paying the reparations rather quickly. During this period Stresemann agreed to the Dawes Plan, the system of loans from the United states helped Germany get back on its feet which got rid of the French in the Ruhr that troubled the Germany people as well as the WR. â€Å"The Dawes Plan sounded the signal for a period of recovery, the scope and intensity of which were unparalleled in recent German History†. This period of stability however fell due to the depression in which the stock markets crashed. Unemployment soared and many lived in poor conditions. The German people had last all hope in the Weimer republic and started looking for radical change like the communists and the Nazis. As a result, Hitler became popular and made promises to the military and to the industrialists that Germany would return to greatness once again. Hitler exploited the trust of the German people to its fullest during these times of hardship so he could gain support to become in full control of the German state. The depression was a main factor in Hitler’s success and the rise of the Nazi party. The weakness of the WR were truly revealed by Hitler and showed its shame and thus gaining support from the public. â€Å"The depression put the wind into Hitler’s sails†

Macbeth Reflection

Macbeth Reflection William Shakespeare has written Macbeth using the reflection of the world which he was familiar with as the play echoes the life and interests of the Ruler and the public. Moreover, James 1st was greatly attracted to sorcery and therefore, witchcraft has a considerable space in this play. Also, Macbeth is a moral lesson as the play is demonstrating the price that the individual has to pay for his sumptuous desires. Shakespeare demonstrated just how the total power has a tendency to corrupt as most often great individuals are immoral. In author era the homicide of a King was the most horrible offense as people believed that the Ruler was selected by means of God and defying it is equal to a protest against God. Lady Macbeth is a provocative character as she was able to identify Macbeths strengths and weaknesses and use them for exploitation. Lady Macbeth character firstly appears in Act 1 scene 5 when she is reading a letter sent from her husband Macbeth. According to a letter, her husband thinks that she is dearest partner of greatness. Therefore, Macbeth is deeply in love with Lady Macbeth as well as he trusts her absolutely. However, she become fascinated with the story told by her husband about the witches tellings. In the letter Macbeth is telling her Whiles I stood rapt in the wonder of it, came missives from the king, who all-hailed me Thane of Cawdor; by which title, before, these weird sisters saluted me, and referred me to the coming on of time, with Hail, king that halt be!. Lady Macbeth realizes a chance to become a queen and she is certain that her husband will acquire this. This is proving that she is despairing to obtain the power. Therefore she is unlike other women these times as back then women used to be seen as gentle beings who had a role of being beautiful as well as giving birth. No one regarded th em as being clever or equivalent to men. Moreover, her relationship with her husband was unlike other couples relationships at the time. Although, Macbeth was a man, he frequently asked his for his wife opinion before doing something as she was the first to hear about his promising future voiced by the sorceresses. Lady Macbeth voices Come, you spirits that tend on mortal thoughts, unsex me here, and fill me from the crown to the toe top-full of direst cruelty! Make thick my blood; stop up the access and passage to remorse She hears that Duncan is coming and that he will stay for the night in the castle. This provides her with an immediate chance to carry out fatal plan. Therefore, we can recognize the evils of her as she desires to become brave enough to convince Macbeth into murdering Duncan. She asks her spouse to Look like the innocent flower, but be the serpent undert which means that he has to be pleasant on the outside and cruel on the inside. However, Macbeth is hesitates to commit the homicide, as he tells her wife that they will not continue any further on this matter. Then Lady Macbeth offends her husbands manhood by telling him that he has to be braver. Moreover, she calls him a coward by telling him that then you were a man, and to be more than what you were, you would be so much m ore the man. It is clearly displaying how devious and controlling she is as Lady Macbeth is emotionally forcing her husband. Lady Macbeth demonstrates her courageous approach in the scene where Duncan is murdered. She was meaning to kill him by herself but she fails when Duncan appears retaining resemblances of her father as she tells her husband that if had he not resembled à ¢Ã¢â€š ¬Ã‚ ¦ Id have done it. Therefore, this is displaying some kindness in her as also it could suggest that after all she is a woman with certain amount of sensitivity. Moreover, she might be displaying her womanlike sensitivity when she requests for help. However, she is still concentrated and determined to carry out the plan as she appointed Macbeth do murder Duncan. Moreover, Macbeth has succeeded in test of love for his wife by doing this. Nevertheless, Lady Macbeth appears being the greater criminal as she recalls the facts which were unnoticed by her husband. She turns out to be furious when she discovers that her husband has not completed the entire plan as she asks him Why did you bring the daggers from the place? They must lie there. Go carry them, and smear the sleepy grooms with blood. Once again, this indicates that she is very controlling as well as that she holds a lot of anger on her husband. Lady Macbeth argues Macbeth of attiring a heart so white which could show that she hates her husband. On the other hand, maybe she is fearful of a prospect of him possibly deceiving himself. Consequently, this before long pushes their relationship into collapse. I particularly liked the quite of Lady Macbeth where she states that A little water clears us of this deed. It means that as soon as they rinse their hands the guiltiness will disappear. The following day when everybody discovers the death of Duncan, Macbeth must assure everyone that he did not slaughtered the King. Therefore he tried to achieve this by use of an exaggerated speech. This apparently made every person appear doubtful of him. Thus, when Lady Macbeth notices Macbeth doing this she puts her greatest efforts in order to move the attention of her husband through falling unconscious. As a result, the people shortly disremember Macbeths scandal and are trying to help out Lady Macbeth. By doing this, she took the attention away from Macbeth. Lady Macbeth understands that the Crown had not made her happy as she had hoped, Noughts had, alls spent, where our desire is got without content.. Therefore, she became mad person terribly wrecked by happenings. For instance, the sleep walking scene is showing that lastly she does feel mortified as well as regretting her own actions. Whats more, gentlewoman requests a doctor to check on Lady Macbeth since she is becoming further troubled as she is sleep walling. This indicates how all the killings in with she assisted is driving her crazy. After all, Lady Macbeth was the main power regarding the murder of Duncan as she had major influence over her husbands actions. I felt sorry for her as she could not abide her guiltiness and for that reason ultimately took her own existence since Lady Macbeth lost the relationship with Macbeth even though they were once very close to each other. Macbeth has found out that Lady Macbeth has perished. However, he had not expressed any sorrow or agony. Therefore this is clearly indicating that the love has left Macbeths heart. Moreover, the guiltiness and heaviness of her actions has overwhelmed her at last and that is why she died. The moral lesson of this play is that Lady Macbeths evils had cracked her and she acquired help. She at the end of the day mourned over her activities which made Macbeth a changed man. Even though, I could still recall her being bold and horrid. In my opinion, William Shakespeare wanted to demonstrate that despite the fact she was wicked and had great power, Lady Macbeth were tremendously shattered in the end.

Essay --

Virginia Henderson was known as a modern legend of nursing. She was born in Kansas City, Missouri on November 30, 1897. Henderson graduated in 1921 from the Teachers College at Columbia University, for a Bachelor of Science degree, which she completed in 1931. She also earned a Master’s of Science degree in 1934 (Tlou, 2001). She wrote and edited numerous editions of the Principles and Practice of Nursing. Henderson’s main idea of nursing was that the unique function of the nurse is to assist the individual, either if they are sick or well. Nursing Theory Virginia Henderson categorized nursing activities into 14 components, based on our basic human needs. She described the nurse's role, as doing for the patient, helping the patient, working with the patient, and with the objective of helping the patient become as independent as possible. The 14 components started off with breathing normally and to eat and drink effectively. You must eliminate body waste, have good posture and gait, and you must sleep and rest. When dressing a patient you should pick appropriate wear. By checking the patient’s temperature, this would keep it sustained. Henderson believed that keeping the body well cleaned and groomed would make the patient more comfortable and confident. You must avoid injuries and dangerous situations, and communicate with others expressing emotions, needs, fears, or opinions. You must respect one’s ethnicity and belief. A nurse should always feel accomplished and participate with patients in recreational activities. Las t of the 14 components of health was to learn from your mistakes as a nurse and to encourage normal development and health. (Dijkstra et al., 2012). Henderson’s nursing theory had four main concepts; individual, e... ...s theory relates to the future practice of nursing because we are being taught to promote independence, which Henderson had a strong belief in. We are to encourage patients to get better again and provide reassurance. Her theory works well with the future of nursing. She focused on patients basic needs which are one of the most important features of nursing. Us as future nurses should promote independence, provide basic necessities, respect the patient’s ethnicity and beliefs, and lastly to assist the individual even if they are not ill. Conclusion Henderson said to be the patient and supplement their strengths and weaknesses according to their needs. She highlighted the importance of promoting independence for future knowledge to patients. Communication is key when dealing with your patient. Without good communication, the level of care and independence weakens.

Were the 1920’s the “Golden Twenties” as Often Portrayed?

From the point of view of farmers, minorities and labor, were the 1920’s the â€Å"Golden Twenties† as often portrayed? BY: ROBERT TANNER U. S.

London: Batsford, 1989 The 1920’s or the â€Å"Roaring Twenties† were a time in U. S. History of great change. This period could be described as the â€Å"Golden Twenties†, where many discoveries and inventions of great importance were made, prosperous industrial growth, increas e in the standard of living, rise of consumerism, and significant changes in people’s lifestyles. But were the 1920’s â€Å"Golden† for everyone? In my essay I will first take a look at the â€Å"Golden† aspects of the twenties, highlighted by some of the inventions and discoveries that took place during the era, which helped define and shape the twenties, and follow that up with the farmers’ point of view on the twenties. First off, let’s take a look at some of the stuff that defined the 1920’s. The 1920s, or the â€Å"Roaring Twenties† were a decade in which nothing big happened, no major catastrophes of large events, at least until the stock market crash of 1929, yet it is one of the most significant decades in U. S. history because of the great changes that came about in American society. The Twenties were known by various images and names: the Jazz Age, the age of the Lost Generation, flaming youth, flappers, radio and movies, bathtub gin, the speakeasy, organized crime, confession magazines, Hemingway and Fitzgerald, Lindbergh, Babe Ruth, Bobby Jones, the Great Crash, Sacco and Vanzetti, AL Smith, cosmetics, Freud, the â€Å"New† woman, the Harlem Renaissance, consumerism, all these images and more are part of the â€Å"Golden† Twenties. In fact, the 1920s may have been the decade of the greatest social change in American history. Reacting perhaps to both the disillusionment from the First World War and against the strictures of Victorian culture, Americans abandoned old ideas with a vengeance and adopted new concepts wholesale. It was also a time of deep divisions: wets (for repeal of prohibition) against dries, town against country, natives versus foreigners, Catholics against Protestants; the decade also saw a resurgence of the Ku Klux Klan and an American sense of alienation from the rest of the world. The decade began amidst the ashes of the Great War, blossomed into a riotous age of spending and profit making, cheap automobiles and new consumer products. Everybody seemed to be on a roll. Then in 1929 the Crash hit the stock market, and for many complicated reasons the Great Depression followed. It was a decade of huge figures, heroes of the kind we don’t see any more, or not often: Charles Lindbergh, Babe Ruth, Bobby Jones and others. Americans started going to the movies and listening to the radio in enormous numbers, and they found themselves becoming more affluent as the markets rose, seemingly without end. It was a time of new awakening for African-Americans, many of whom had fought in France, and the Harlem Renaissance opened Americans to Black literature, poetry, music and other arts of a quality never seen before. Literary figures like Fitzgerald, Hemingway and Thomas Wolfe brought white American literature to a new plane as well. The Progressive movement was not dead in the twenties, a Progressive Presidential candidate got almost 5 million votes in 1924, but it was not an activist decade. Everybody knew what Harding meant when he called for a return to â€Å"normalcy,† even hough there was no such word in the dictionary. The Twenties began on a somber note, rose to great heights of excitement. Then on Black Tuesday, October 29, 1929, it all came crashing down, and things were never the same again, but then again, they never are. â€Å"1† A â€Å"Golden Age†, Americans in the 1920s had discovered many things. They had more leisure time, and they discovered radi o and movies. The first â€Å"talkie,† â€Å"The Jazz Singer† was produced in 1927; color pictures followed a few years later. Americans of that era loved film stars like Charlie Chaplin, and they honored heroes like Charles Lindbergh. They had more time to participate in and watch sporting events, and Babe Ruth became the first athlete to earn a salary of $100,000 for a season. When reminded that that was more than President Hoover made, the Babe replied, â€Å"I had a better year. † It was also a golden age of literature as well. Scott Fitzgerald, Ernest Hemingway, Thomas Wolfe, Marjorie Rawlings, the Black writers mentioned above and many others brought American literature to new heights. â€Å"2† As for Business in the 1920s: It was the Age of the Consumer. During the 1920s everybody seemed to be buying everything. Cars, radios, appliances, ready-made clothes, gadgets and other consumer products found their ways into more and more American homes and garages. Americans also started buying stocks in greater numbers, providing capital to already booming businesses. All the signs pointed upwards, and starry-eyed men and women began to believe that it was going to be a one-way trip, possibly forever. Henry Ford’s assembly line not only revolutionized production, it democratized the ownership of the automobile. Ford showed that handsome profits could be made on small margin and high volumes. By 1925 his famous Model-T sold for under $300, a modest price by the standards of the 1920s. Americans had never had it so good. Thanks to pioneers like Charles Lindbergh, the airplane began to come of age in the 1920s. Although used for various purposes in the World War, airplanes were still exotic gadgets until after Lindbergh’s flight, when planes began to carry mail as well as passengers for travel rather than just for thrills. Regularly scheduled flights began, and airports were constructed to handle passengers and small amounts of cargo. The end was in sight for railroad domination of the transportation industry. â€Å"2† Not everyone prospered in the 1920s. Farmers, becoming increasingly more skillful and efficient in producing food, found that laws of supply and demand still plague them. The more they produced, the lower prices tended to fall. In the early 1920s bread was at its lowest price in 500 years relatively to other necessities. It was still tough to make a living down on the farm. The 1920s afforded unprecedented economic opportunities for many Americans, but not for the nation's farmers. They had enjoyed unusual prosperity during World War I, owing to the increased demand for American agricultural products in war-torn Europe, but in the 1920s they were plagued by low prices for agricultural products, high costs for producing these goods, and heavy debt. Increases in the American farmers' productivity created surpluses that drove commodity prices down and lowered their income. While prices for agricultural products remained low, costs for land, machinery, equipment, labor, transportation, and taxes were rising, creating greater disparity between a farmer's costs and income. The pervasive â€Å"farm problem† of the 1920s was complex. The market compensated a farmer's increased productivity and efficiency with a lower standard of living. Collectively, Americans devoted too many resources: land, labor, and capital, to agriculture. Consequently, the supply of agricultural products far outstripped the demand for them. The problem, however, is much easier to diagnose in retrospect than it was during the 1920s. Arguing that the problem with American agriculture was overproduction seemed paradoxical to contemporaries who closely associated the independent farmer with the essence of American virtue and character, someone to be emulated, not discouraged, from increasing his crop yields. Instead of realizing the link between low prices and overproduction, farmers blamed their adversity on insufficient credit, high interest rates, inadequate tariffs, and declining world trade. Overwhelmed by the seriousness of their problems, farmers looked to the federal government for assistance. Farmers' demands for federal help ran against the popular political mood of the 1920s, which demanded a reduction in government involvement in business. Moreover, the growing urban character of the nation weakened farmers' political influence. Yet agriculture had powerful allies in Congress. In 1921 two Republican legislators from Iowa, Sen. William Kenyon and Congressman L. J. Dickinson, organized the â€Å"farm bloc,† a bipartisan group of congressmen that exerted political pressure for legislation to alleviate the farmers' economic misery. During President Harding's administration this legislative caucus advocated generous credit, higher tariffs, and cooperative marketing, all proposals that treated symptoms rather than the core problems, production surpluses and price disparities. From 1920 to 1921, farm prices fell at a catastrophic rate. The price of wheat, the staple crop of the Great Plains, fell by almost half; the price of cotton, still the lifeblood of the South, fell by three-quarters. Farmers, many of whom had taken out loans to increase acreage and buy efficient new agricultural machines like tractors, suddenly could not make their payments; throughout the decade, farm foreclosures and rural bank failures increased at an alarming rate. Agricultural incomes remained flat, with rural Americans' wealth falling far behind their urban counterparts. Rural electrification increased at a snail's pace, with more than 90 percent of American farms still lacking power into the 1930s. The proportion of farms with access to a telephone actually fell during the Roaring Twenties. So, it’s no great exaggeration to say that for rural America, the Great Depression began not in 1929 but in 1920, and it continued for an entire generation. The roaring prosperity of America's cities during the 1920s made the privation of rural life all the more painful, by contrast. The divide between Haves and Have Nots in the 1920s was the divide between city and country. â€Å"3† In Conclusion, the 1920s, â€Å"Roaring† Twenties, or â€Å"Golden† Twenties, can be viewed as two distinct points of views. That of the urban society, which experienced an increase in the standard of living, rises of consumerism, and significant changes in their lifestyles. Times were good, and era of the 20s could truly be viewed and defined as the â€Å"Golden† Twenties. On the other hand, there was the farmers’ point of view, which could be described as the exact opposite. By becoming increasingly more skillful and efficient in producing food, the farmers had found that the laws of supply and demand were not working in their favor. The more they produced, the lower prices tended to fall. Hence, times were tough, and it was hard for them to make ends meet. Overall, one would almost have to reword the 20s, maybe by calling them the â€Å"Golden† twenties for some but not all. Endnotes ( Henry J. Sage, The Roaring Twenties.

English Speech †After The First Death Essay

English speech Good morning, teachers and year 11’s, Identity is one of the main themes in the novel ‘After the First Death’ by Robert Cormier. Identity defined is the individual characteristics by which a thing or person is recognized or known by. Throughout the book, Kate, the main character is constantly changing her emotions and the way she acts showing her different sides. When the main character, Kate appears, She is said to be ‘silent’. This tells the reader, that she does not want to confront the terrorists, which also brings us to the point that Kate is not a very brave person. When the reader first meets Kate it had said that,† She regarded then in shocked silence, mouth agape, eyes wide open with disbelief.† This tells the reader that she is terrified and scared. The central theme of self identity is presented multiple times through main characters such as Kate. She struggles with finding her true identity and becoming brave. My visual representation represents how Kate and the children on the bus are pure and superior to Miro and artkin. The black and white are conflicting colours and white rocks show that the children and Kate are pure and the black shows Miro and Atkin. The black represents the colours of the balaclavas and the colour of Miro’s skin. The black also is a less superior colour than white, representing that the children and Kate are more important. The ratio of white to black rocks demonstrations that there more innocent characters than immoral characters in the novel. The jar is the thing that all the characters have in common; they are trapped in this and cannot get out. This represents the situation they are all in. Wanting to get out but cant. Thankyou†¦

Molar Mass of a Solid Essay

Abstract: The purpose of this experiment is to determine the molar mass of an unknown solid. The freezing point of a solvent (Cyclohexane) was determined, and compare to the freezing point of Cyclohexane with the addition of two different concentration of unknown solid. The pure substance of Cyclohexane has defined physical properties. However, when a solute is added these properties are determined by the amount of solute added, also known as colligative properties. The temperature of the freezing point was lowered when the solid was added and it decreased as the concentration of the solid increased. The molality of the solute was determined, which was then used to calculate the molar mass of the solid for both trials. An average of the molar mass of the unknown solid was calculated to be 286.87+1.796g/mol with a %RSD of 0.626%. The purpose of the experiment was to obtain the molar mass of an unknown solid. The molar mass is determined by dissolving the unknown compound into a pure liquid with defined physical properties, in this case Cyclohexane. When dissolving a solute, it forms a homogeneous solution, in which the solvent of the solution physical properties are not longer defined, but depends on the amount of solute added. Whenever a substance is dissolved in a solvent, the vapor pressure decreases. When the vapor pressure decreases, it also lowers the boiling and freezing point of the solvent and increases the osmotic pressure. These four properties are known as the colligative properties, the magnitude of the changes depends on the amount of solute dissolve; the changes are directly proportional to each other. The higher the solute concentration, the higher the changes of vapor pressure, therefore, a lower freezing point. It is hypothesized that the freezing point temperature will decreased, if there is a higher concentration of the solid added to the soution. Vapor pressure is th e  pressure exerted by a vapor when the vapor is in a state of dynamic equilibrium with its liquid. When a nonvolatile solute is dissolves in the solvent, solute molecules occupy a part of the surface area. This allows molecules into the vapor state, lowing the vapor pressure of the solvent. When the vapor pressure lowers, the boiling point elevates, due to the presence of the solute. Solute added to the solvent affects the freezing point, the energy of the solvent lowers to increase the magnitude of the intermolecular forces for the molecules to get together to form a solid. The colligative properties are useful for determining molar masses of unknown nonvolatile solute. At low concentrations of a nonvolatile solute, the freezing–point of depression of a solvent can be determine by Tf = Kf (solvent) -Tf (solution) = Kf m. Changes in freezing point Tf are directly proportional to the molality, m, of the solute in solution (molality, m = mol solute/ kg solvent). The freezing-point constant, Kf for Cyclohexane is 20ËšC †¢ k/mol, which is used to obtain the amount of moles of solute in the solution, which is inversely proportional to the change of freezing point Tf. The molal mass obtained is essential to obtain the molar mass of the unknown solid (solute). The molal mass shows the unknown amount of moles of solute are need it per kilogram of solvent. Acquiring the number of moles of solute and analyzing it with the grams of solute measured in the laboratory obtaining the molar mass of the unknown solute.i The cooling behavior of a solution different from a pure liquid solution when a solute it’s added. Te temperature at which the solution begins to freeze is lower than the pure solvent. The freezing point also lowers when there is a higher concentration of solute added to the solution. The molar mass of unknown solid can be determined by any of the colligative properties, the freezing point is not an exception and by knowing the mass of solute and temperature of the freezing point, the molar mass can be obtained. Discussion: The freezing point depression is a colligative property of solutions, which is based only on the amount of solute added and not the defined chemical and physical properties of the substance. The freezing point of Cyclohexane observed was 4.97ËšC, from the cooling curve (Figure 1). Freezing point values of Trial 1 and Trial 2 were collected, to compared to the freezing point of Cyclohexane and determine he depression of the solute. The unknown solid yielded a freezing depression of 3.64ËšC for trial 1, and 2.84ËšC for trial 2 (Figure 2 & 3). These values were compared to the original mass of unknown solute added to the Cyclohexane and the approximate molar mass of  the unknown solid. The molar mass that was calculated for trial 1 was 288.14-g/mol, while trial 2 was 285.60-g/mol (Table 3). The average of the molar mass was calculated, and the molar mass of the unknown solid observed was approximately 286.87-g/mol. When calculating the standard deviation was obtain only +1.796g/mol when comparing both trials to the mean. The values are apparently close up together, making them highly precise, however, is unknown if the values are accurate, the unknown solid actual molar mass still unknown. The relative standard deviation percent, obtained was 0.626% (Table 3); this measurement expresses precision of the data, the smaller RSD the greater the precision for the average value of the data. The %RSD, is extremely low, making it the results a tremendously precise data of the mean. However, there was a possible error that could have affected the results. The error occurred during recording the cooling temperature of trial 1, the ice melted and the test tube was removed to add more ice into the beaker. Also, while recording the temperature of the Cyclohexane upon addition of unknown solid, the sample was not stir and therefore the value could have probably been invalid. Constant stirring of solution would have assured an even mix of the solute particles and a more accurate freezing point. These small errors could have affected both trials creating a higher observed molar mass value for both trials. Conclusion: The experiment allowed for the determination of freezing point of Cyclohexane based on a logger pro software with calibrated thermometers to be approximately 4.97ËšC (Table 1). Freezing point depression was observed when two trials of different concentration of the unknown solid were added to the Cyclohexane. As the concentration of the unknown solid increased, the freezing point of the solution was also lowered (Table 2). As seen on Figure 4, when placing all three graphs it is visible, when solute is added a lower freezing point is observed. Using experimental measurements, the molar mass of the unknown solid was calculated to be 286.87+1.796g/mol. Based on the relative standard deviation percent (%RSD) of 0.626%, shows a highly precise measurements of unknown solid molar mass when compared to the mean values.

Effectiveness of the Transmission of Monetary Policies and Lessons Essay

Effectiveness of the Transmission of Monetary Policies and Lessons Learned in 2007 and 2008 Global Financial Crisis - Essay Example It has also resulted in a number of debates as regards the effectiveness of the transmission mechanism of monetary policies. In the past, monetary policy has been associated with a financial stability of an economy. The problem that a majority of countries face is concerned with the effectual transmission mechanism of an effective monetary-policy. A number of lessons can be learned regarding the effectiveness of the transmission mechanism of monetary policy by central banks in the year 2007 and 2008. The lessons would be based on interest rate, inflation, exchange rates, balance sheet, expectations, as well as moral hazards that characterized the market prior, during and after the 2008 global economic-crisis. A Brief State of the 2007 Financial Crisis and Failure of the Monetary Policy Transmission Mechanism Although financial crisis is not a unique occurrence, the financial crisis of 2007 was more global than other economic crises experienced in the past (Mankoff, 2010). It is also regarded as the most impactful relative to other proceeding financial crises. Due to its high level of degree in terms of impact and globalization, a large number of monetary policymakers were compelled to utilize both conventional and unconventional financial policies. A majority of economic analysts as well as financial institutions in the world were surprised by the fast pace at which the subprime crisis in the US led to a world financial crisis (Cecchetti, 2009, p. 53). The global financial crisis led speedily to a world economic crisis. This fast pace left a considerable number of individuals in the business and financial circles with unanswered questions regarding the effectiveness of the transmission mechanism of monetary policy. In particular, the 2007 and 2008 financial crisis questioned the effectiveness of various institutional frameworks (Mankoff, 2010). It also questioned the national and internal monetary instruments in ensuring financial stability at the global level. In relation to Shiller’s (2008) argument, attention has been paid to the role and operation of financial markets, as well as financial institutions. Specifically, questions regarding the effectiveness of financial institutions and markets to price and administer risk have been raised. Analysts observe that there have been inability of private sector to manage risk effectively, and failure of public sector’s supervision of the financial markets (Mankoff, 2010). Interest rate While the financial world changed in the year 2007, the monetary instruments were not updated to handle the change (Swagel, 2009, p.43). The instruments were not transmitted effectively to realize positive impact. Initially, interest rates were traditionally treated as the main financial instrument that would protect an economy against financial difficulties, as well as enhance economic growth. A large number of emerging economies, including India, lowered their interest rates in an anticipation th at both prices and output would respond effectively. However, both output and prices did not respond in respect to the anticipation. An interest rate is majorly used in managing the supply of money in an economy. Interest rate has been observed by many individuals as a key monetary instrument in controlling lending and borrowing between financial institutions and consumers. The borrowing and lending is also executed amongst financial institutions. In the event that there is a high supply of money in an economy, a central bank would opt to raise the level of an interest rate. In this regard, credit availability is likely
