Juicy Fruit Investigation :: Papers

Juicy Fruit Investigation Aim: To find out if temperature affects the amount of juice the enzyme pectinase releases from an apple. Prediction ========== I predict that the temperature the pectinase will work best in is 30Â ° - 40Â °, I think this will be the temperature the pectinase will be able to break down the most fruit into fruit juice. I do not believe the enzyme will work above 45Â ° as it would become denatured. This is because I know most enzymes (similar to proteins) stop working/get destroyed above this temperature, as they are made up of protein. I also know that the temperature enzymes work best in the body at body temperature; 37Â ° therefore I believe the higher the temperature is without going over 45Â ° the faster the molecules will move and hit the enzyme molecules. An enzyme works when a substrate molecule bumps into a molecule of the correct enzyme, they fit together into a depression on the surface of the enzyme molecule. When this movement takes place the depression is called an 'active site'. A reaction takes place and the substrate products are released separately. Because the substrate molecules are different shapes they will only fit into certain enzymes. When the enzyme reaches a temperature too high it will change shape, therefore the substrate molecule would not fit. When the enzyme reaches a temperature that is low (or lower than 37Â º) the molecules will not move as fast as they will have less energy. This therefore means the enzyme molecules will not hit the substrate molecules as often as they would in a higher temperature meaning less juice will be released.

Delivering a Persuasive Speech

Delivering a Persuasive Speech Douglas A. Parker August 13, 2001 |  Amazon Products | |Subject(s):   Language Arts/Reading and Public Speaking |Links of Note | |[pic] | |Overview:  Ã‚   Students need to understand that how they say something and how they physically present |Persuasive Essay Topics  form| | | |themselves are just as important as what they say.By understanding the dynamics involved in effective |Curious Castle Classroom. | | | |persuasive speaking, students will improve their overall confidence in communicating. | | | | |Purpose:   The purpose of this lesson is to improve students’ oral persuasion techniques by understanding |Writing the Persuasive | | | |the appropriate speaking skills.The lesson is presented in second person, making it more meaningful as a |EssayCurious Castle | | | |resource for the students, and easier for the teacher to use as a handout. |Classroom | | | |Objectives:  Ã‚   Students will be able to: | | | | |1) Demonstrate the appropriate classroom public speaking and listening skills (e. . , body language, |[pic]   | | | |articulation, listening to be able to identify specific examples of the speaker's coordination of talking |[pic] | | | |and action) that would be necessary to influence or change someone's mind or way of thinking about a | | | | |topic. | | | |2) Define the elements of persuasion. | | | | |3) Recognize the elements of personal credibility. | | | | |4) Develop methods to analyze other students’ speeches. | | | | |5) Understand outlining main ideas. | | | |6) Create a persuasive speech. | | | | |Resources/Materials:  Teacher-prepared topics for persuasive speeches. | | | | |Assessments:  Ã‚  Ã‚   The Class will assess each speaker's performance in terms of voice and body coordination, | | | | |and in terms of persuasiveness.Each class can develop performance assessments such as rubrics to | | | | |facilitate this process. | | | | |Teacher's Anticipatory Set: | | | | |During class discussion, define and explain how people make decisions based on what they see and hear. | | | |Explain that sometimes we have to use skills to convince others about our positions. Have the students | | | | |recall and list their own experiences trying to convince their friends about something, and then ask them | | | | |to share these with the class. | | | |   | | | | |Activities and Procedures:   Delivering a Persuasive Speech   | | | | |   | | | | |The Procedure | | | | |Pick a proposition that not everyone would agree with such as: â€Å"nuclear power plants are superior energy | | | | |sources. †Ã‚   Write a 6 to 8 – minute speech in outline form to persuade the group. | | | | |The Lesson:  Your Voice and Body are Your Best Tools | | | | |You are a natural persuader! You have done it all your life.Every time you enter a conversation, you | | | | |engage in elementary persuasion techniques. It is true, that any time you make a statement of fact, you | | | | |are asserting its validity and assuming that your listener agrees. | | | | |This speech goes further than a normal conversational assertion: now you have to assume that not everyone | | | | |will agree with you from the start, and it is your job to make them see things your way.The goal of this | | | | |speech is to change someone's mind or way of thinking about a topic. This is not a speech to sell, as you | | | | |do not ask that the listener do anything except to agree with you or to begin to listen to your way of | | | | |thinking. Your message is, of course, very important in this speech, but your voice and body language are | | | | |even more important. Here you will see how your delivery can help. | | | |There are several important aspects of presentation to keep in mind: | | | | |1)  Body language  Ã¢â‚¬â€œ make sure that you have a proper posture. If your shoulders are sagging and your legs | | | | |are crossed, you will not appear as being sincere and peo ple just will not accept your message. | | | | |2)  Articulation  Ã¢â‚¬â€œ articulation means how your total vocal process works. There are several steps to this | | | | |entire process.First, you need air from the lungs, your vocal cords in your larynx must be working, your | | | | |mouth and tongue must be in sync, and you have to make sure that you have got some saliva in your mouth to | | | | |keep things oiled. You should be aware of your physical makeup to be able to understand how you speak. | | | | |3)  Pronunciation  Ã¢â‚¬â€œ pronounce each word. Avoid slang, except to make a point, and do not slur your words. | | | | |Avoid saying, â€Å"you know. | | | | |4)  Pitch  Ã¢â‚¬â€œ pitch refers to the highs and lows of your voice. Whatever you do, avoid a monotone! | | | | |5)  Speed  Ã¢â‚¬â€œ your speed, or pace, is an important variable to control. Between 140-160 words per minute is | | | | |the normal pace for a persuasive speech. Any faster and you may appe ar to be glib; any slower and you | | | | |sound like you are lecturing.If you are not sure about your speed, tape yourself for one minute and then | | | | |replay it and count the number of words you used in the minute! The human ear and brain can compile and | | | | |decode over 400 spoken words per minute, so if you are going too slow your listeners' minds are going to | | | | |start to wander as the brains finds other ways to keep themselves occupied. | | | | |6)  Pauses  Ã¢â‚¬â€œ the pause, or caesura, is a critical persuasive tool. When you want to emphasize a certain | | | | |word, just pause for one second before; this highlights the word.If you really want to punch it, pause | | | | |before and after the word! | | | | |7)  Volume  Ã¢â‚¬â€œ volume is another good tool for persuasive speech, but you should use it with caution. If you | | | | |scream all the way through your speech, people will become accustomed to it and it will lose its | | | | |effectiveness. On the other hand, a few well-timed shouts can liven up the old speech! Try to â€Å"project† | | | | |or throw your voice out over the entire group – speak to the last row. | | | |8)  Quality  Ã¢â‚¬â€œ quality of voice is gauged by the overall impact that your voice has on your listeners. | | | | |Quality of voice is the net caliber of your voice, its character and attributes. Try to keep your vocal | | | | |quality high; it is what separates your voice from everyone else's. | | | | |9)  Variance  Ã¢â‚¬â€œ variance of vocal elements is your most important consideration of all! One of the most | | | | |persuasive speakers in modern history was Winston Churchill.One of his most remarkable qualities was his | | | | |ability to vary the elements of his voice. He would start with a slow, laconic voice and then switch gears| | | | |to a more rapid pace. People were light-headed after listening to him! Even if you have no desire to run | | | | |for political office, you ca n still use the tools of variance. Change your pitch, volume, and speed at | | | | |least once every 30 seconds, if only for just one word. Never go more than one paragraph without a vocal | | | | |variance.This keeps your group locked into your speech, if for no other reason than it sounds | | | | |interesting! Let the words speak for themselves; reflect their nature through your voice. If you use the | | | | |word â€Å"strangle,† say it with a hint of menace in your voice. If you say the word â€Å"heave,† let the group | | | | |feel the onomatopoeic force behind it. If you say the word â€Å"bulldozer,† make it sound like a titan | | | | |earthmover, not like a baby with a shovel. | | | |The Strategy: Appear Rational | | | | |When you are trying to convince someone of something, you must first establish your credibility, or in | | | | |other words, you must sell yourself before you sell your message. If people feel that you are not being | | | | |reasonable or rational, you do not stand a chance. You must be committed to the ideals and goals of your | | | | |speech and what you are saying. Do not use words such as â€Å"maybe† or â€Å"might†- use positive words such as | | | | |†will† and â€Å"must.    | | | | |You are the authority figure in this speech, so you had better supply enough information to prove your | | | | |points so that you can seem knowledgeable, and you had better know your material cold. People can usually | | | | |spot someone who is trying to â€Å"wing† a speech. You should also appear to be truthful -even when you are | | | | |really stretching a point. If you do not appear to be earnest, even if your message is the 100% truth, | | | | |people will doubt your word and tune out your speech. | | | |Lastly, do not be afraid to show a little emotion – this is not a sterile or static speech. Your body and | | | | |voice must match the tone of your words. If your language i s strong, you must present a physical force to | | | | |go along with your delivery. | | | | |The Comments and Goals | | | | |Self-control? | | | | |You cannot sit back and let your words do all of the talking.You must use your total self to deliver your| | | | |message, and this means that you will have to expose a little of your personality to the group. Your group| | | | |will be supportive. | | | | |The Group Reaction | | | | |The group has two major criteria to consider after each member's speech. First, the delivery. Were the | | | | |speaker's body, words, and actions in synchronization and harmony? Did one support the other or was there | | | | |tension between the body and the voice?Secondly, were you persuaded? Why or why not? Discuss what makes| | | | |a persuasive speech work and how the intangibles effect a positive outcome. | | | | |More Information? | | | | |For more information and help with public speaking, contact:   | | | | |http://capital. net/~bps2/   | |

Left hand of darkness essays

Left hand of darkness essays I think that the book The Left Hand of Darkness, by Ursula Le Guin, should be a book that everyone at ETHS should read. This book is a classic science fiction book with many added advantages. The book is about a man who is trying to peacefully convince a new world of people to join in a trade agreement with his home word as well as many others. The book promotes peace and peaceful discussions over war, which has no place in the book at all. It also forces the reader to look at sex in a different way. The inhabitants of this planet do not have a gender most of the time, which makes open thinking a necessity. Science fiction books can be wonderfully exciting and fun to read, but many kids in our school today do not know that. Many students are simply not exposed to science fiction, and think that science fiction is only for science people and dorks. This is obviously not true, but how would they know? They have never read any science fiction in school, and if they do not read it on their own, they may never read science fiction. This would be a tragedy, for there are so many books that are so engrossing that they could really bring out the reader in students. For example, Dune, by Frank Herbert, is an outstanding piece of literature, but unless you read science fiction, you probably have never heard of it. The Left Hand of Darkness does not have the same draw as Dune, but it comes close. When Genly, the main character, and Estraven, his friend, are crossing the great ice, as proposed on page 201, it is slightly reminiscent of the sand crossing in Dune. However, Dune dos not have the sam e use of local folklore in the same way. Interspersed in the book The Left Hand of Darkness, there are chapters which are simply stories that help the plot along. One example is chapter 12 on page 162. This chapter is about Meshe who has been to the center of time and therefore knows everything that has, is and will happe ...

Marcus Garvey Essays - Black Star Line, Harlem Renaissance

Marcus Garvey Essays - Black Star Line, Harlem Renaissance Marcus Garvey Historians familiar with Garvey's career generally regard him as the preeminent symbol of the insurgent wave of black nationalism that developed in the period following World War I. Although born in Jamaica, Garvey achieved his greatest success in the United States. He did so despite the criticism of many African-American leaders and the covert opposition of the United States Department of Justice and its Bureau of Investigation (forerunner of the FBI). As a young man, Garvey had preached accommodation and disavowed political protest, advocating loyalty to the established colonial government. His views, however, underwent a radical transformation shortly after he arrived in the United States in 1916. The emergence of the radical New Negro movement, which supplied the cultural and political matrix of the celebrated Harlem Renaissance, to a large extent paralleled Garvey and his post-World War I "African Redemption" movement. Garvey established the first American branch of the UNIA in 19171918 in the midst of the mass migration of blacks from the Caribbean and the American South to cities of the North. It was also a time of political awakening in Africa and the Caribbean, to which Garvey vigorously encouraged the export of his movement. In the era of global black awakening following World War I, Garvey emerged as the best known, the most controversial, and, for many, the most attractive of a new generation of New Negro leaders. Representative Charles B. Rangel of New York has noted that "Garvey was one of the first to say that instead of blackness being a stigma, it should be a source of pride" (New York Times, 5 April 1987). Black expectations aroused by participation in World War I were dashed by the racial violence of the wartime and postwar years, and the disappointment evident in many black communities throughout the U.S., Africa, and the Caribbean allowed Garvey to draw dozens of local leaders to his side. Their ideas were not always strictly compatible with Garvey's, but their sympathy with his themes of "African redemption" and black self-support was instrumental in gathering support for the movement from a vast cross-section of African-American society. Similarly, Garvey's message was adopted by a broad cross-section of educated and semi-literate Africans and West Indians hungry for alternatives to white rule and oppression. The postWorld War I years were thus a time when a growing number of Africans and West Indians were ready for change. In most colonial territories, Africans, like African Americans, were disappointed when expected postwar changes failed to materialize. The Garveyist message was spread by sailors, migrant laborers, and travelling UNIA agents, as well as by copies of its newspaper, the Negro World, passed from hand to hand. In the Caribbean, what has been termed the "Garvey phenomenon" resulted from an encounter between the highly developed tradition of racial consciousness in the African-American community, and the West Indian aspiration toward independence. It was the Caribbean ideal of self-government that provided Garvey with his vocabulary of racial independence. Moreover, Garvey combined the social and political aspirations of the Caribbean people with the popular American gospel of success, which he converted in turn into his gospel of racial pride. Garveyism thus appeared in the Caribbean as a doctrine proposing solutions to the twin problems of racial subordination and colonial domination. By the early 1920s the UNIA could count branches in almost every Caribbean, circum-Caribbean, and sub-Saharan African country. The Negro World was read by thousands of eager followers across the African continent and throughout the Caribbean archipelago. Though Caribbean and African Garveyism may not have coalesced into a single movement, its diverse followers adapted the larger framework to fit their own local needs and cultures. It is precisely this that makes Garvey and the UNIA so relevant in the study of the process of decolonization in Africa and the Caribbean. As if in confirmation of the success with which Garveyism implanted itself in various social settings, when Garvey himself proposed to visit Africa and the Caribbean in 1923, nervous European colonial governors joined in recommending that his entry into their territories be banned. Many modern Caribbean nationalist leaders have acknowledged the importance of Garveyism in their own careers, including T. Albert Marryshow of Grenada; Alexander Bustamante, St. William Grant, J. A. G. Smith, and Norman Washington Manley of Jamaica; and Captain Arthur Cipriani, Uriah Butler, George Padmore, and C. L. R. James of Trinidad. Before the Garvey and UNIA Papers project was established, the only attempt to edit Garvey's speeches and writings was the Philosophy & Opinions of Marcus Garvey, a propagandistic apologia compiled

Canadian Criminal Justice System Essay Example | Topics and Well Written Essays - 1000 words

Canadian Criminal Justice System - Essay Example This paper will analyze the judicial system of Canada and the application of criminal responsibilities for rape crimes, in this country. Canadian Criminal Justice System The legal system of Canadian is based on English Common Law (old), which were brought by explorers and colonists. The law of the immigrants prevailed over the rules of the Canadian settlers, and the law of the immigrants guided the conduct of people in Canada for a long time. The judicial system is crucial in a country; it facilitates the application of justice in the society, and it helps punish the law breakers. Most aspects of the Canadian criminal justice system are unique and different from other systems in the world. However, the Canadian system of criminal justice inclines towards utilizing the due process model. The suspects’ rights are respected and protected until their guilt is proven, without doubt. This is one of the most significant tenets; therefore, a person charged with offense (criminal) is o nly proved guilty by a jury. Otherwise, a suspect of a criminal offense is treated and believed to be guilty during the process of trial, in a law court. In the event that the police are convinced that their grounds are adequate to proceed with a criminal charge against an accused person, then the accused is apprehended to answer the charges before the court (Howe & Russell, 2001). Further, the accused person is entitled to an affordable bail. In the event that the issue reaches the stage of trial, the crown attorney who is prosecuting the accused person assumes the responsibility of proving that indeed the suspect committed the offense. For instance, if it is a murder charge, the crown attorney will call the people who witnessed the accused committing the crime, and in other forms of crimes like rape or robbery, the attorney will call the victims to testify against the suspect (Howe & Russell, 2001). Depending with the strength of evidence presented by the prosecutor, the suspect m ay call on his own witnesses who would bring reasonable doubt to the case. In such an event, the jury is left with the mandate to pass judgment, with regard to the available evidence and witnesses. At this stage, the case goes to sentencing stage where the judge passes the sentence, either acquitting the accused if there is no substantive evidence, or a jail term in proportion with the nature of the criminal offence (Ehrlich, 2001). This model utilizes the adversarial system where the judge acts as an independent arbiter, and he is the one who adjudicates between the prosecutor and his witnesses and the accused and his witnesses. Apparently, the paper has disrobed the judicial system that exists in Canada, and it will shift the focus on investigating the applicability and assignment of criminal responsibility to sexual offenders. Rape is described as the act of forcibly having sexual contact with a female partner, without her consent. Sexual offences are further incorporated with ha ving sexual contact with persons who are minors. Sexual contact with minors is another serious criminal offence, which can attract heavy fines and long jail sentences. The pursuits of these cases are based on the two popular models of justice, which are employed by the Canadian law enforcement agencies, as well as the judicial system (Ehrlich, 2001). The initial model that is employed in assigning criminal responsi

Marketing Essay on Ryan Air Example | Topics and Well Written Essays - 1500 words

Marketing on Ryan Air - Essay Example It is held that that growth of the purchasing power of the European consumers would help in steering the rate of passenger inflow. RyanAir thus being the low-cost airlines can effectively sustain its market position (Mayer, 2008, p.3). Social With a growth in the per-capita income of the European households the lifestyle of such people is also held to counter changes. The number of vacation goers is thereby held to increase which in turn would help RyanAir gain an increase in passenger traffic during weekends (Hoffmann, 2007, p.13). Technological RyanAir is gradually developing on the technological situation by dearth of developing its website from only a booking enabled site to contain enhanced information pertaining to flight destinations. Further the company is working with other complimentary business firms like travels and hospitality to enhance its online service and information dimension (Bearne, 2010). Legal RyanAir’s flight operations are continuously under legal surv eillance. During 2005 the airlines company was sued by a British Court by around ?24,000 pertaining to its erroneous representation of flight prices as against the Consumer Protection codes of the region (Rush and Ottley, 2006, p.286). Again during 2010 the company was made bound by European Union regulations to reimburse the reservation amount to passengers that had gone disrupted owing to rise of ash clouds (EU Business, 2010). Environmental The management body of RyanAir is continually investing billions of pounds to focus on reducing the level of carbon emissions by around 50 percent. The company is stilling facing complaints from European Union and other political factions stating it to be a high carbon-emitting company (BBC News, 2007). SWOT Analysis of RyanAir Strength RyanAir a low cost airliner is gaining increased popularity among vacation goers and business travellers in the European markets. The company acting effectively on its online platform gains the potential to exp and its business and consumer portfolio. It also reflects the potential in running airlines rendering low-carbon emissions in the European region. Weakness The company owing to its managerial ineptness tends to face legal suits for not being effective in looking after the problems of passengers. Legal suits filed pertaining to its price misrepresentation and delay in reimbursement tends to dilute its brand image in the low-cost airlines market of Europe. Opportunity RyanAir in terms of economic and social developments of the people pertaining to the European region tends to gain hold of larger opportunities pertaining to increasing the passenger inflows. This increase in the passenger traffic would thus help the airlines enhance its revenue and market share in the European region. Moreover the enhancement of the online paradigm also helps the company gain the advantage of other companies collaborating with it to render services to consumers. Threat Regulatory climate of the European region is continually changing with rise in threat coming from the growth of terrorism and epidemics like flu and SARS. These changes in European regulations happen to render impact on disrupting its flight operations along the European region. Marketing Objectives of RyanAir Area1: Public Relations S-The company can
