The Importance of the House in The Strange Case of Dr. Jekyll and Mr. H

The Importance of the House in The Strange Case of Dr. Jekyll and Mr. Hyde In The Strange Case of Dr. Jekyll and Mr. Hyde, Steveson used the architecture of Dr. Jekyll's house very intelligently. The house can be regarded to be parallel to Dr. Jekyll's double personality. Throughout the book, the house lends itself as a powerful prop, by which it is possible for Dr. Jekyll to use his house even when he is in the form of Mr. Hyde. The house, like Dr. Jekyll, has a dark side. On the front side of the house, it seems to be an elite, upper class, respectable home. However, the rest of the house is quite the opposite. As the book described it – 'discolored wall on the upper; and bore in every feature the marks of prolonged and so did negligence.'; Therefore the back door could be used by Mr. Hyde, with very few suspecting Mr. Hyde of having any connection to Dr. Jekyll. Steveson fit the architecture of the house into the story cleverly. The house supports Dr. Jekyll's secret of being Mr. Hyde at times. The house symbolizes the double personality of its ow ner. Therefore Dr. Jekyll and his house have parallel characteristics. We are introduced to the back door right at the beginning of the book. The door is said to be – ' equipped with neither bell or knocker, was blistered and distained.'; Along with the introduction of the door is the introduction of Mr. Hyde. Mr. Hyde's appearance is described as 'something displeasing, something downright detestable.'; So right from the beginning, we are aware of Mr. Hyde's connection with this mysterious door. Mr. Enfield's story on page 2 gives a good understanding of the shady character of Mr. Hyde. A quote from the book that best describes this is ' The next thing was to get the money; and where do you think he carried us but to that place with the door? – whipped out a key, went in , and presently came back with the matter of ten pounds in gold and a cheque for the balance on Coutts's, drawn payable to bearer, and signed with a name that I can't mention.'; But as the story progresses we learn that the house belongs to Dr. Jekyll. The fact that Dr. Jekyll is only seen in the front of the house, which is well furnished and respectable, brings about the contrasting features of the house. This is also a good time to note that this contradiction of the two sides of the house signifies that Dr. Jekyll is obviously hid... ...ekyll was a man, who had always followed the rules of society. He was a respectable man, and had never had any adventures. By becoming Mr. Hyde, with the help of his knowledge of science he was satisfying his evil side. But he could not altogether forget about society. Although Dr. Jekyll's reputation was still important to him, and he becomes a hypocrite in the process, he found a way to hide his hypocrisy and keep his reputation as it was. This is why he had to use his private and public identity the way he did. The house clearly caters to Dr. Jekyll's double personality. Steveson uses the house as a prop throughout the book. The story never would have worked if the house's architecture was not like it was. It is almost too much of a give-away that the house was made in this way. But no reader if the book would realize this unless, it was thought about more, or studied. In conclusion, the house of Dr. Jekyll is much more important then one would think at the beginning of the book. If the architecture was not planned by Steveson the way it was, the story would not have been as good. Steveson used the house greatly to his advantage, and greatened the mystery of the novel.

Nonverbal: Woman and Victoria Essay

All types of communication interaction involve two major components in terms of how people are perceived: verbal, and nonverbal. These cues such as facial expressions, posture, verbal intonations, and other body gestures accompany our words in order to create a clear message. Every person is continuously communicating even when they are not saying a word, thus, it is possible to send an exclusively non verbal message but it is not possible to send an exclusively verbal message. Nonverbal cues in the interaction are always more powerful indicators of what a speaker means and what the speaker feels because non verbal cues have not been learned and therefore are not manipulated. In the movie Victor Victoria, nonverbal cues are used to emphasize the gender of characters. There are certain nonverbal cues that accentuates a woman. One example from the movie is Victoria’s long hair. Long hair in the 1930’s was how a woman was identified. Toddy cuts Victoria’s long hair to create the illusion that she is man. Along with a woman’s long hair, their breast were also a symbol of womanhood. Victoria is asked to wrap her breast as well as walk with her chest sticking out to emphasize that she is man, because walking with their chest out was a mans way of showing confidence. In a scene in the movie Victor is going to say cheers before drinking and he is laughed at because traditionally women are the one’s that cheer before drinking. Another gender based nonverbal cue is in the nightclub, during performances the women dance and the men are in the orchestra. It was normal for the women to be dancers in that era because a woman is built a lot more flexible so manipulating their bodies is easier although there are exceptions. A characteristic that separates men and women is pride. Although I am not saying women do not have pride, men are willing to go above and beyond to protect their pride; an example of this is when Toddy accepts the ride back to their hotel even though in reality they were not staying in a fancy hotel. Victoria tries to deny the ride in order for their lie not be discovered. Toddy accepts the ride to show off that they’re wealthy even if they are not. This scene in my eyes is one of the great barriers that distinguishes men and women. In addition to the things that accentuates a woman, there also exist the things that accentuates a man. For example the way men greet each other. I man greeting another man would simply shake hands, but a man greeting a woman would kiss her hand. There is also the nonverbal cues of what a gay man should look like. In this movie we have the bodyguard, and the boxer who are two gay men but King Marchand refuses to admit it due to the nonverbal cue that they are both strong men. Also, when the gangsters think that King Marchand they try to get rid of him by paying him off because gangsters can’t be seen as gay because they are usually strong feared men. Nonverbal cues are used in this movie to emphasize the socio-economic class of the characters. In the opening scene of the movie we see Victoria singing, we automatically know she is poor by the clothes she is wearing. She has a broken glove, and no fancy jewelry. This nonverbal cue was intended to demonstrate that she is a struggling singer. In a later scene we see Victoria walk by a restaurant and see a fat man enjoying a large variety of pastries. The size of the man is intentional and is what let’s the audience know that he is wealthy because he obviously eats a lot of pastries which only a rich man could afford in this time period. Overall I must say that nonverbal cues account for most of the perceptions of things that we have. In this movie the nonverbal cues play a large part in demonstrating to the audience who these characters are. Whether the nonverbal cue represents gender of economic level, it is safe to say that the nonverbal cues are all intentional created to create a clearer message throughout this movie.

Behavior Leadership Theory

What really makes a good leader? Psychologist and managers tried to answer this question. â€Å"Chronologically, the first answer to what makes a good leader was that leaders are not made, they are born† (Fairholm, 1991). This was the first theory of Leadership, the Great Men Theory. Many other theories were divided by Fairholm and these are the following: theories based on who the leader is, wherein this group focuses on the leader‘s characteristic; theories based on what the leader does, wherein the behavior theory belong to this group.It is focused on studying leaders’ behavior so that it can be reproduced by followers; and the theories based on the Environment of the Leadership. Leadership is a difficult topic to study because leadership is a â€Å"fuzzy† concept. For decades, social scientists and practitioners have been struggling to come up with the ultimate definition of leadership, to explain its mechanisms, and to draw the line between leadership and management. They have produced a number of definitions and theories.Long time ago, determinants of leadership has been identified by behavioral theorists, so that people could be trained to be leaders. Since the best styles of leadership can be learned, training programs have been developed to change managers' leadership behaviors. During the World War II, the leaders of the academy left the Isle of Traits and set sale for the Isle of Behaviors by the 1940s. They suspected that the X and Y Theory of Leadership of Myers or Briggs, was some kind of fraud. The military wanted to know if leaders could be trained, and if so, what behaviors made them most effective.The Academy of Leader Professors wanting to get tenure, fame in time of world crisis, and fortune decided that some new theory of leadership must be found or all their jobs would be as extinct as dinosaurs. Working with the Army and with universities, two biggest â€Å"Page#2† bureaucracies in the world, it was mostl y about transactional behavior, being autocratic or democratic to increase the transaction rate or quality. The game of life in organizations was never to be transformed and their quest was to find universal leader behavior styles that correlate with effectiveness and are optimal transactions in all situations.Squire Fleishman and Sir Katz set off for the Isle of Behavior in separate ships as they are desperate to establish a behavioral settlement, but found out that Scribe Lewin had already established a behavioral settlement and an Iowa University since 1938. On the Isle of Behaviors, leader (transactional) behaviors became observable and their study turned objective and measurable. Different Universities wanted to make its mark and study what do leaders do by using some statistical methods, then the Ohio State and Michigan University competed for the education of the peasants.Fleishman became King of Ohio State and Katz was made King of Michigan University. Lewin was already King at Iowa. Each mustered their armies and prepared to battle for leader behavior territory. Sir Mintzberg, knighted by the Canadians, resettled in the Isle of Behavior and decided to go and look to see if leaders did any planning, organizing, controlling, or leading. He actually observed and recorded the progress what transactions that leaders do. The world was shocked to discover, that leaders had a hectic, frantic, and fragmented transaction life, and did little of the behaviors thought to take place.Some leaders were only figureheads, but he did confirm Sir Merton's view, but noting all the roles that leaders do. While the Isle of Behavior was oversupplied with two-factor studies of behavior and observations of roles here and everywhere, that great explored, Prince Yukl decided that process was more important than some list of universal behaviors. And by 2001, Prince â€Å"Page#3† Howell and Knight Costley joined the search for process. They still liked to isolate and measu re behaviors, but wanted to do this in the study of processes. They made great maps of the world of leadership, charting each territory.Leaders were reduced from traits or greatness to just psychoalgebraic behavioral equations, to styles or just transactions. But alas most of the Leader Behavior Academy had already set sail for the Isle of Situation. It seemed obvious that Traits and Behaviors to be effective depended upon the Situation. If there were universal behaviors, they are not optimal in all situations. Therefore a great expedition set forth to the Isle of Situation in the 1960s, with new waves of migration each decade since. This is where the arts of transformation were rekindled. The behavior of Leadership has two main theories, transaction and transformation.This is what we call the â€Å"X† dimension of behavior leadership theory. It is the X dimension that focuses on the Behavioral School of leadership. The X dimension runs from Transactional to transformational leadership, as studied by Burns (1978) and Bass (1985). This is a classic dualism in leadership studies. Burns looked at modal thinking (the means over ends reasoning) in the early stages of development and held that the leaders are transactional in their behaviors. Transactional leadership requires a shrewd eye for opportunity, a good hand at bargaining, persuading, reciprocating (Burns, 1978:169).A transformational leader, on the other hand, recognizes and exploits an existing need or demand of a potential follower and looks for potential motives in followers, seeks to satisfy higher needs, and engages the full person of the follower. Eventually transformational leaders were thought to engage in behaviors that â€Å"Page#4† changed the game, even changed the world. Douglas McGregor described Theory X and Y in his book, The Human Side of Enterprise, that X and Y theory each represent different ways in which leaders view employees.Theory X managers believe that employees are motivated mainly by money, are lazy, uncooperative, and have poor work habits. Theory Y managers believe that subordinates work hard, are cooperative, and have positive attitudes. Theory X is the traditional view of direction and control by managers. The average human being has an inherent dislike of work and will avoid if he or she can. Because of this human characteristic of dislike of work, most people must be controlled, directed, and threatened with punishment to get them to put forth adequate effort toward the achievement of organizational objectives.The average human being prefers to be directed, wishes to avoid responsibility, has relatively little ambition, wants security above all. This theory leads naturally to an emphasis on the tactics of control – to procedures and techniques for telling people what to do, for determining whether they are doing it, and for administering rewards and punishment. Theory X explains the consequences of a particular managerial strateg y. Because its assumptions are so unnecessarily limiting, it prevents managers from seeing the possibilities inherent in other managerial strategies.As long as the assumptions of Theory X influence managerial strategy, organizations will fail to discover, let alone utilize, the potentialities of the average human being. Theory Y is the view that individual and organizational goals can be integrated. The expenditures of physical and mental effort in work are as natural as play or rest. â€Å"Page#5† External control and the threat of punishment are not the only means for bringing out effort toward organizational objectives. Commitment to objectives is a function of the rewards associated with their achievement.The average human being learns, under proper conditions, not only to accept but also to seek responsibility. The capacity to exercise a relatively high degree of imagination, ingenuity, and creativity in the solution of organizational problems in widely, not narrowly, di stributed in the population. Under the condition of modern industrial life, the intellectual potentialities of the average human being are only partially utilized. Theory Y's purpose is to encourage integration, to create a situation in which an employee can achieve his or her own goals best by directing his or her efforts toward the objectives of the organization.It is a deliberate attempt to link improvement in managerial competence with the satisfaction of higher-level ego and self-actualization needs. Theory Y leads to a preoccupation with the nature of relationships, with the creation of an environment which will encourage commitment to organizational objectives and which will provide opportunities for the maximum exercise of initiative, ingenuity, and self-direction in achieving them. Note that with Theory Y assumptions, management's role is to develop the potential in employees and help them to release that potential towards common goals.Theory X is the view that traditional management has taken towards the workforce. Many organizations are now taking the enlightened view of theory Y. A boss can be viewed as taking the theory X approach, while a leader takes the theory Y approach. Notice that Maslow, Herzberg, and McGreagor's theories all tie together: Herzberg's theory is a micro version of Maslow's theory (concentrated in the work place). McGreagor's Theory X is based on workers â€Å"Page#6† caught in the lower levels (1 to 3) of Maslow's theory, while his Theory Y is for workers who have gone above level 3.McGreagor's Theory X is based on workers caught in Herberg's Hygiene Dissatisfiers, while Theory Y is based on workers who are in the Motivators or Satisfiers section. Whatever theory applied by any organization , the greatest chance of being successful is when all of the employees work toward achieving its goals. Since leadership involves the exercise of influence by one person over others, the quality of leadership is a critical determina nt of organizational success. Thus, leaders study leadership in order to influence the actions of his followers toward the achievement of the goals of the organization.Leadership studies can be classified as trait, behavioral, contingency, and transformational. Earliest theories assumed that the primary source of leadership effectiveness lay in the personal traits of the leaders themselves. Yet, traits alone cannot explain leadership effectiveness. Thus, later research focused on what the leader actually did when dealing with employees. These behavioral theories of leadership sought to explain the relationship between what the leader did and how the employees reacted, both emotionally and behaviorally. Yet, behavior can't always account for leadership in different situations.Thus, contingency theories of leadership studied leadership style in different environments. Transactional leaders, such as those identified in contingency theories, clarify role and task requirements for employ ees. Yet, contingency can't account for the inspiration and innovation that leaders need to compete in today's global marketplace. Newer transformational leadership studies have shown that leaders, who are charismatic and visionary, can inspire followers to transcend their own self-interest for â€Å"Page#7† the good of the organization.

A Walk To Remember

What salient point struck you most regarding the meaning of true love? The point in the movie that struck me the most regarding the meaning of true love Is that when you love someone, you would do everything and anything Just to make sure that the person you love will be happy and loved always. It Is true In the movie when London did his best to show how much he loved Jamie although Jamie was not her Ideal girl and she was going to die soon and leave him forever.London changed for the better hen he came to love Jamie. He realized that the most important thing for him was their love for each other. 2. Cite situations in the film which reflects the element of true love. * London changed his bad behavior and habits. He believed that it would make him to be worthy of Jasmine's love. *London stood up for Jasmine's sake against his friends. Although he knew that some of them would criticize him, he still did it for her. *London tried to fulfill all of Jasmine's wishes which she could neve r do because of her illness.Although London did not have a good relationship with his father, he still asked for his help to cure Jamie. *London married Jamie despite the fact that she would die soon. *Although years has passed, London still hold on to his promise to love Jamie forever 3. What lesson can you derive from the movie? The movie teaches me that loving someone is not all about happiness. It is also about the sufferings and challenges that a couple should face together in order to let their love last forever.A person would not be afraid to suffer and feel pain because e/she knows that the joy and affection he/she gets from loving someone is greater than those. Also, once a person learns how to truly love, he/she would be more than willing to fully accept the other one despite of her/his shortcomings as a person and as a partner. He/she would understand and care for her/him until the end. A true love means that a person Is willing to do and sacrifice everything Just to let the other person be happy and feel cherished with all the moments that they are together. . Are there differences in society's expectation in one's partner and the qualities that really count? There are differences in society's expectation in one's partner and the qualities that really count. Most people would have an ideal partner, which they assume, who would make them happy and complete. But in reality, there are many instances that the person who is destined to be loved by someone is really different from his ideal partner and his ideal situation of his love story.It does not matter if one has a particular standard for his partner. Because once he experiences how to truly love someone, he would realize that loving Is not something that should be planned ahead. What really Important Is that he knows how to value and love the other person despite the circumstances which he does not expect to come. A Walk To Remember By Emplace in the movie that struck me the most regarding the mea ning of true love is that when person you love will be happy and loved always.It is true in the movie when London did his best to show how much he loved Jamie although Jamie was not her ideal girl e/she knows that the Joy and affection he/she gets from loving someone is greater love means that a person is willing to do and sacrifice everything Just to let the other 4. Are there differences in society expectation in one's partner and the qualities that really count? There are differences in society expectation in one's partner and the truly love someone, he would realize that loving is not something that should be planned ahead. A Walk to Remember IntroductionACME Financial is a fast growing company that owes part of its growth to several recent acquisitions. ACME Financial now wants to consolidate the companies’ information technology resources to eliminate redundancy and share information among the new companies. The Chief Information Officer (CIO) has oversight responsibility for the project and has hired Client/Servers R Us to develop the architecture for the new corporate information system. Joe Consultant of C/S R Us presented 3 client/server designs to the CIO and is requesting the CIO to select one. The CIO is not sure which middleware design is best for the company’s goals. The CIO has asked Chris Consultant to present the advantages and disadvantages for each of the alternatives.Background ACME Financial Incorporated (AF Inc.) is an investment banking company that provides an on-line service that allows their clients to access account and market information. ACME Financial Inc. recently acquired several small and medium sized companies throughout the country, each with their own financial and accounting systems. Almost all of the companies have developed their own application software for their analysts’ use in their daily jobs, but only a few provided on-line account service. The analytical tools rely on near-real time market data and historical market data.The CIO wants to consolidate the financial and accounting information into a corporate information system that can support decision support applications for corporate management. Naturally, since the computer hardware is different for different companies, the CIO expects to upgrade the hardware to accommodate the new Information Technology (IT) system. The CIO will select the best analytical software as the standard software used by all company analysts. Each local site will be expected to provide an on-line service for their customers.Customers will be given the necessary application software to access their account in formation. Finally, ACME Financial has developed special data mining software that gives them a competitive advantage. AF Inc. offers their customers investment advice based on the information derived by the data mining software. Each account manager receives the information and then provides tailored recommendations to each customer based on their portfolio.System RequirementsThe following list of system requirements reflects the system’s priorities (listed roughly in order of priority): 1. Availability: The CIO’s number one priority is high availability. AF Inc. markets their reliability and feels that most clients choose them for their dependability. The CIO wants to maximize the system’s availability. To achieve high availability, if a regional office cannot provide support then a customer must always have access to the on-line service through a different office. 2. Data Integrity: The requirement for data integrity varies within the system. The most importa nt data are customer’s transactions.It is essential that a customer’s transaction is never lost and the system must guarantee that each transaction is completed. In contrast, data lost from the high data rate inputs, such as Reuter’s and the NYSE, are easily recovered during the each broadcast so it is not critical if some data are lost during a broadcast. 3. Performance: Financial markets are highly volatile; time sensitivity of data is measured in minutes. Millions can be lost if information is delayed getting to the analysts. The system must be able to support information broadcast throughout the network.4. Security: The CIO is concerned about the security of the data mining software and the information produced by the data mining software. The Chief Executive Officer thinks the data mining information software provides a competitive advantage for the company. If an unauthorized user had access to the information they could steal the data mining applications or steal the information produced by the data mining software. In either case, the perpetrator could make the same investment recommendations as AF Inc. account managers. Therefore, if competitors had access to the information the results could be financially devastating to the company.The CIO is concerned that a competitor could pose as a customer and hack into the highly sensitive information through his on-line service account. 5. Growth: The CIO envisions an incremental migration process to install the new system due to the magnitude of the change. Also, he expects that AF Inc. will continue to grow and acquire more companies. The CIO wants to be able to develop more application software as new customer services are added. The CIO also wants to add more near-real time information sources to  the system.6. Backup and Recovery: The CIO understands that the system will encounter problems from time to time. A key factor in determining the system’s success is how quickly the system can recover from a failure. Backup and recovery must be smooth and non-disruptive. One way to ensure that the system can easily recover from a system crash is to make sure the data is duplicated elsewhere on the system. The corporate database is the primary back up for each of the regional offices.ConfigurationEach local office (Northeast, Northwest, Southeast, Southwest) has accesses a regional information hub. Local offices use client software to access the local application server. These application servers access the local databases for almost all of the information needed on a daily basis. For access to information needed less frequently the application software should access the central database at corporate headquarters. Each regional database has only the subset of information that is relevant for its area, whereas the corporate headquarters maintains all of the information from each region as well as data that is unique to corporate applications, such as additional accounting and company financial information.The corporate office is also responsible for the data mining software and information. Each of the regional databases is connected with high capacity links to the corporate database. Finally, the corporate office receives information from Reuter’s, NYSE, NASDAQ, and other financial markets. The information flow fluctuates daily from 30 – 40 KBps to 4 – 5 MBps. Twenty-five percent of the information is immediately broadcast to the regional offices to support the on-line account service. All the information is filtered and stored in the database.Architectural AlternativesAlternative I: The Database Management System This alternative takes advantage of the extended functionality provided by the popular relational database management companies, such as Oracle and Sybase. All information is delivered into the system where it is immediately stored into one of the databases. The relational database management software is res ponsible for the distribution of information throughout the system. Clients communicate  with the databases through Standard Query Language (SQL).Corporate and regional databases are kept synchronized using features supplied by the RDBMS software. Transactions are guaranteed by using special Transaction Processing Software. The vendor-supplied RDBMS software is responsible for back-up and recovery of all the databases. Data security is handled at the row level within each database. This means that clients can only receive records for which their user has permission. Existing application software may have to be modified to use SQL. Alternative II: Common Object Request Broker Architecture (CORBA) This solution depends on CORBA to tie together the clients and databases. CORBA is responsible for distributing data across the system. The RDBMS software is still responsible for the back-up and recovery, but the databases are kept synchronized using CORBA as the primary transport mechani sm for the data.Clients, application servers, and databases communicate to each other through CORBA’s transport mechanism. Existing application software would be wrapped in IDL to communicate with other applications. Special near-real time handling application software would send the information to each of the regional offices where it would be directed to clients that subscribe to the information. Alternative III: Message and Queuing (M&Q) The message and queuing design uses commercial M & Q software combined with a transaction processing product to ensure customer’s transactions are completed. Dec Message Queue and MQ Series are some of the leading products for messaging and queuing software. Clients communicate to other entities using messages. Messages are deposited in queues and the message and queuing middleware is responsible for message distribution to the appropriate clients. The software applications will be modified to send and receive messages from queues.Q uestions to Answer (Total 100 points)The case study must be discussed covering the designs and these questions with your teammates, but your final write-up should be your collaborative work. Doing research on specific products for the assignment should certainly be a team activity. The total length of the write-up should probably not exceed 5 pages. 1. Describe in more detail the architecture of each architectural alternative. To do this you will need to flesh out the specifics of the various parts. This will require some research on the  products indicated (or other comparable products that you locate).Note that some services are automatically provided when a particular product is purchased, while others must be developed to satisfy the system requirements. You should describe what services are automatically provided by the products, which services would need to be developed, and how services should be distributed across the network. (40 points) 2. Evaluate each of the alternativ es against the system requirements, discussing the advantages and disadvantages of each. (You may assume that the hardware will support all solutions.) In your analysis you might consider issues such as which alternative gives the system developers the most flexibility, which alternative provides easiest maintenance, and which alternative requires the least modification to the current system. Other hints for system comparison are listed below. (40 points)3. Prioritize each alternative or suggest a different solution if you think it superior to the presented alternatives. (20 points) Suggestions on how to proceed 1. There is not enough information to make an informed decision about each of the alternatives. As a team, allot a percentage of your time to discover which products offer what type of services. You do not have enough time to do a complete market survey so be selective. 2. If you depend only on marketing information you may find that the alternatives are equivalent. So you m ight want to go beyond the market literature in doing your research for this assignment.3. As you do your analysis, pay particular attention to some of the following kinds of issues: a. How well does the architecture support the basic system functionality requirements? b. How much run time performance overhead does the architecture impose? c. How well will specific products handle the high volume of data? d. How will each architecture handle occasional peak loads? e. How easy is it to customize the system to new requirements? 4. In your analysis, when you are considering costs, you do not need to consider the actual product cost. (It may be impossible to get actual product costs anyway.) Instead, evaluate cost with respect to the amount of customized software that will be necessary to implement each alternative, and how this might affect long-term maintenance costs, time to implement, flexibility, etc.

Chemistry Experiment

Experiment 1: TLC Analysis of Analgesic Drugs 1/23/2011 Purpose: The goal of this experiment is to test our knowledge and understanding of TLC analysis by having us do a TLC analysis of analgesics to figure out their main chemical components. Calculations: 1. ) Rf = Distance spot traveled/ distance solvent traveled Results: Table 1: TLC Analysis Analgesic Drugs| Rf Value| Acetaminophen| 0. 323| Aspirin| 0. 597| Caffeine| 0. 081| Unknown 154 (Plate 1)| 0. 081, 0. 306, 0. 597| Ibuprofen| 0. 698|Salicyclamide| 0. 587| Unknown 154 (plate 2)| 0. 079, 0. 397, 0. 587| Discussion: The goal of this experiment was to use TLC Analysis to determine the analgesic drug present in the unknown solution 154. One observation of the unknown spotting solution was that it was cloudy. After forming the unknown spotting solution it was then heated to make it a more saturated solution thus enabling the spots on the TLC plate to contain more of the drug making it easier to compare it with the other drugs.Aft er the TLC plates were developed and visualized first through UV light and then through an Iodine chamber ( though no more spots were visualized with iodine chamber) , Rf values were then taken of each spot on the plate. The Acetaminophen had a value of 0. 323, Aspirin had a value of 0. 597, Caffeine had a value of 0. 081, Unknown 154 on the first plate had 3 different values; 0. 081, 0. 306, 0. 597, Ibuprofen had a value of 0. 698, Salicylamide had a value of 0. 587, and Unknown 154 on the second plate had three different values as well; 0. 079, 0. 97, and 0. 587. Through analysis it was determined that unknown 154 was Aspirin. This was found by comparing the Rf values of all the analgesic drugs to unknown 154. After comparing them it was seen that the Rf value for Aspirin matched one of the Rf values for unknown 154 exactly. The determination of the unknown was further supported by looking at the samples in solution. Both the unknown 154 and Aspirin were cloudy in solution thus fu rther supporting the identification of unknown 154. In this experiment there were not too many sources of error.One source could have been that the glassware being used may not have been cleaned thoroughly before using it thus possibly contaminating the unknown or the other analgesic drugs. This Experiment definitely was an efficient way to help determine what type of drug the unknown 154 was but there are a few improvements that could have been done to help better determine the unknown. One improvement could be to examine the solvent used because different solvents create different separations between spots.Another improvement could be to also run an Infrared Spectroscopy on the unknown and known compounds. Answers to Questions: 1. ) When running TLC plates three common mistakes that can be made are using a pen instead of a pencil to mark on the plate, using the wrong solvent, and touching the plates thus getting grease on them. 2. ) The Starting line and the spotting line are mark ed with pencil rather than pen because the ink from the pen would move with the solvent front thus interfering with the results. 3. ) Acetaminophen Aspirin CaffeineIbuprofen Salicylamide Pretty much all of the functional groups can determine the polarity of a compound. This includes Amides, Acids, Alcohols, Ketones, Aldehydes, Amines, Esters, Ethers, and Alkanes. Even though they all can determine the polarity of the compound Amides, Acids, Alcohols, Ketones, and Aldehydes are the most polar and therefore are the best at determining polarity in compounds. 4. ) In order of increasing polarity Ibuprofen is the least , then it is Aspirin, then Salicylamide, then acetaminophen, and Caffeine is the most polar. 5.

Chemistry Experiment Experiment 1: TLC Analysis of Analgesic Drugs 1/23/2011 Purpose: The goal of this experiment is to test our knowledge and understanding of TLC analysis by having us do a TLC analysis of analgesics to figure out their main chemical components. Calculations: 1. ) Rf = Distance spot traveled/ distance solvent traveled Results: Table 1: TLC Analysis Analgesic Drugs| Rf Value| Acetaminophen| 0. 323| Aspirin| 0. 597| Caffeine| 0. 081| Unknown 154 (Plate 1)| 0. 081, 0. 306, 0. 597| Ibuprofen| 0. 698|Salicyclamide| 0. 587| Unknown 154 (plate 2)| 0. 079, 0. 397, 0. 587| Discussion: The goal of this experiment was to use TLC Analysis to determine the analgesic drug present in the unknown solution 154. One observation of the unknown spotting solution was that it was cloudy. After forming the unknown spotting solution it was then heated to make it a more saturated solution thus enabling the spots on the TLC plate to contain more of the drug making it easier to compare it with the other drugs.Aft er the TLC plates were developed and visualized first through UV light and then through an Iodine chamber ( though no more spots were visualized with iodine chamber) , Rf values were then taken of each spot on the plate. The Acetaminophen had a value of 0. 323, Aspirin had a value of 0. 597, Caffeine had a value of 0. 081, Unknown 154 on the first plate had 3 different values; 0. 081, 0. 306, 0. 597, Ibuprofen had a value of 0. 698, Salicylamide had a value of 0. 587, and Unknown 154 on the second plate had three different values as well; 0. 079, 0. 97, and 0. 587. Through analysis it was determined that unknown 154 was Aspirin. This was found by comparing the Rf values of all the analgesic drugs to unknown 154. After comparing them it was seen that the Rf value for Aspirin matched one of the Rf values for unknown 154 exactly. The determination of the unknown was further supported by looking at the samples in solution. Both the unknown 154 and Aspirin were cloudy in solution thus fu rther supporting the identification of unknown 154. In this experiment there were not too many sources of error.One source could have been that the glassware being used may not have been cleaned thoroughly before using it thus possibly contaminating the unknown or the other analgesic drugs. This Experiment definitely was an efficient way to help determine what type of drug the unknown 154 was but there are a few improvements that could have been done to help better determine the unknown. One improvement could be to examine the solvent used because different solvents create different separations between spots.Another improvement could be to also run an Infrared Spectroscopy on the unknown and known compounds. Answers to Questions: 1. ) When running TLC plates three common mistakes that can be made are using a pen instead of a pencil to mark on the plate, using the wrong solvent, and touching the plates thus getting grease on them. 2. ) The Starting line and the spotting line are mark ed with pencil rather than pen because the ink from the pen would move with the solvent front thus interfering with the results. 3. ) Acetaminophen Aspirin CaffeineIbuprofen Salicylamide Pretty much all of the functional groups can determine the polarity of a compound. This includes Amides, Acids, Alcohols, Ketones, Aldehydes, Amines, Esters, Ethers, and Alkanes. Even though they all can determine the polarity of the compound Amides, Acids, Alcohols, Ketones, and Aldehydes are the most polar and therefore are the best at determining polarity in compounds. 4. ) In order of increasing polarity Ibuprofen is the least , then it is Aspirin, then Salicylamide, then acetaminophen, and Caffeine is the most polar. 5. The Acetic Acid in the TLC solvent is used to increase the polarity of the developing solvent thus reducing the amount of attraction the polar compound has for the stationary phase. 6. ) TLC is a good way to determine an unknown, but not to determine composition of an unknown. O ne good way to determine the composition of an unknown is to run an Infrared Spectroscopy which when analyzed functional groups can be identified.

Culture Practice Paper Essay Example | Topics and Well Written Essays - 1000 words

Culture Practice Paper - Essay Example Maya civilization was first established in the pre-classic period. It reached its peak in the classic period and continued until the arrival of the Spanish in the year 1525. At its epitome, it became one of the richest cultures in the world. Maya civilization and Mesoamerican civilization are quite similar due to cultural diffusion and interactions within the societies. Maya civilization helped in the development of famous cities such as, Tikal, Copan, Altun Ha and many others. Maya civilization had intensive agricultural practices with corn as the staple food. Historical anthropologists assert that religion rather than sciences was almost part of every life in Maya civilization. Therefore, more than 40 cities states had temples and pyramids for warships until the fall of Maya civilization in the year 1542. Anthropologists have identified religion, the cosmic tree, the sacred time, deities such as (male/female, old/young, human/animal) language, public life among others as some of the cultural themes in Mayan civilization. Each of these cultural terms played greater roles in the development and peaceful existence of the society. Therefore, these cultures were highly valued to the extent that societies could not do without them. The Mayan society therefore made it necessary to preserve them. Religion, one of the cultural practices in Maya civilization played major role in shaping the society. The fact that religious kings were at the top most level of hierarchy gave religion an upper hand in Maya civilization. For instance, taxation and law were viewed as religious practices, though they were in the civic administrative docket. Other religious aspects were realized on the time factor. The Maya Shaman would interpret the time cycles and give them a prophetic outlook on the past or future within the views of their prescribed calendars. In many cases, the gods would be appeased if by any means the shaman -prophesy would spell
