The Opening Scene of Macbeth Sets the Mood of the Whole Play-Discuss

Macduff (Macbeth) 1 Macduff (Macbeth) Macduff (Macbeth) Dan O'Herlihy as Macduff in Orson Welles' dubious film adjustment Macbeth (1948) Creator William Shakespeare Play Date Source Family Macbeth c. 1603-1607 Holinshed's Chronicles (1587) Lady Macduff, spouse Son, (name obscure) Antagonist to Macbeth; murders him in the last demonstration. Despondency thy beguile/And let the heavenly attendant whom thou has served/Tell thee Macduff was from his mother’s belly/Untimely tore (5. 10. 14-16) Role Quote Macduff, the Thane of Fife, is a character in William Shakespeare's Macbeth (c. 603-1607). Macduff assumes a urgent job in the play: he associates Macbeth with regicide and in the long run slaughters Macbeth in the last demonstration. He is the fundamental opponent, yet the saint, in the play. The character is first known from Chronica Gentis Scotorum (late fourteenth century) and Orygynale Cronykil of Scotland (mid fifteenth century). Shakespeare drew for the most part from Holins hed's Chronicles (1587). In spite of the fact that portrayed irregularly all through the play, Macduff fills in as a foil to Macbeth, a figure of ethical quality, and an instrument to the play’s wanted extraction of gentility. OriginThe by and large plot that would fill in as the reason for Macbeth is first found in the compositions of two recorders of Scottish history, John of Fordun, whose exposition Chronica Gentis Scotorum was started around 1363 and Andrew of Wyntoun's Scots refrain Orygynale Cronykil of Scotland, composed no sooner than 1420. These filled in as the reason for the record given in Holinshed's Chronicles (1587), on whose accounts of King Duff and King Duncan Shakespeare to some degree based Macbeth. Macduff first shows up in Holinshed's account of King Duncan after Macbeth has murdered the ruler and ruled as King of Scotland for 10 years.When Macbeth calls upon his aristocrats to add to the development of Dunsinane mansion, Macduff maintains a strategic di stance from the request, stirring Macbeth's doubts. Macduff leaves Scotland for England to push Duncan's child, Malcolm, into taking the Scottish seat forcibly. Then, Macbeth kills Macduff's family. Malcolm, Macduff, and the English powers walk on Macbeth, and Macduff murders him. [1] Shakespeare follows Holinshed's record of Macduff intently, with his lone deviations being Macduff's disclosure of Duncan's body in 2. 3, and Macduff's short meeting with Ross in 2. 4.Historically, the Clan MacDuff was the most remarkable family in Fife in the medieval ages. [2] The remains of Macduff's Castle lie in East Wemyss burial ground. Job in the play Macduff first talks in the play in 2. 3 when he finds the cadaver of King Duncan in Macbeth’s mansion. He raises an alert, illuminating the château that the ruler has been killed. Macduff starts to associate Macbeth with regicide when Macbeth says, â€Å"O, yet I do apologize me of my wrath/That I killed them† (2. 3. 103-104). Strik ingly, Macduff’s name doesn't show up in this scene; rather, Banquo alludes to him as â€Å"Dear Duff† (2. 3. 75). In 2. Macbeth has left for Scone, the old illustrious city where Scottish rulers were delegated. Macduff, in the mean time, meets with Ross and an Old Man. He uncovers that he won't go to the crowning celebration of Macbeth and will rather come back to his home in Fife. Be that as it may, Macduff escapes to England to join Malcolm, the killed King Duncan’s senior child, and persuades him to return Macduff (Macbeth) to Scotland and guarantee the seat. Macbeth, in the interim, visits the Three Witches again after the ghost of Banquo shows up at the imperial meal. The Witches caution Macbeth to â€Å"beware Macduff, be careful the Thane of Fife† (4. 1. 87-88).Furthermore, they illuminate him that, â€Å"The intensity of man, for none of lady conceived/Shall hurt Macbeth† (4. 1. 96-97). Macbeth, dreading for his situation as King of Scotla nd, arranges the passings of Macduff's significant other, youngsters and family members. Macduff, who is still in England, learns of his family’s passings through Ross, another Scottish thane. He joins Malcolm, and they come back to Scotland with their English partners to confront Macbeth at Dunsinane Castle. After Macbeth kills the youthful Siward, Macduff stands up to Macbeth. In spite of the fact that Macbeth accepts that he can't be killed by any man conceived of a lady, he before long discovers that Macduff was â€Å"from his mother’s belly/Untimely ripped† (5. 10. 15-16). The two battle, and Macduff kills Macbeth offstage. Macduff at last presents Macbeth’s head to Malcolm, hailing him as ruler and approaching different thanes to pronounce their faithfulness with him (5. 11. 20-25). 2 Analysis Macduff as a foil to Macbeth As a supporting character, Macduff fills in as a foil to Macbeth; his trustworthiness straightforwardly appears differently in re lation to Macbeth’s moral depravity. [3] In a trade between the Scottish thane Lennox and another master, Lennox talks of Macduff’s trip to England and alludes to him as â€Å"some heavenly angel† (3. 6. 6) who â€Å"may before long come back to this our enduring nation/Under a hand accursed† (3. 6. 48-49). The play positions the characters of Macduff and Macbeth as blessed versus detestable. The differentiation among Macduff and Macbeth is complemented by their ways to deal with death. Macduff, becoming aware of his family’s passing, responds with a tormented anguish. His words, â€Å"But I should likewise feel it as a man† (4. 3. 223), show a limit with respect to enthusiastic affectability. While Macbeth and Lady Macbeth demand that masculinity suggests a disavowal of feeling (1. 7. 45-57), Macduff demands that passionate profundity and affectability are a piece of being a man.This translation is bolstered by Macduff’s response upo n his revelation of Duncan’s carcass and the reverberation of Macduff’s words when Macbeth reacts to the updates on Lady Macbeth’s demise. Macduff battles to discover the words to communicate his anger and anguish, crying, â€Å"O frightfulness, awfulness, horror† (2. 3. 59). In some stage translations, Macduff’s character advances from a condition of stun to one of furious alert. [4] This stands out distinctly from Macbeth’s popular reaction to the declaration of his wife’s passing: â€Å"She ought to have kicked the bucket in the future/There would possess been an energy for such a word/Tomorrow, and tomorrow, and tomorrow† (5. . 17-19). Macbeth’s words appear to communicate a ruthless indifferenceâ€she would have kicked the bucket anywayâ€and maybe even propose that he has lost the ability to feel. Macduff as an ethical figure Although Macduff comes to speak to a sort of â€Å"goodness† in obscurity unive rse of Macbeth, Shakespeare additionally considers some shakiness in his character. This turns out to be generally obvious in 4. 3 when Macduff joins Malcolm in England. In this scene, the play has moved from the tumult in Scotland to England. In the trade between the two Scotsmen, Malcolm is obviously in charge and powers Macduff to inspect and accommodate with himself his own good code.In a snapshot of emotional incongruity, Macduff starts the discussion asking Malcolm to battle for Scotland instead of to lament, not realizing that Malcolm has just masterminded English military help (4. 3. 134-136). Malcolm controls Macduff, scrutinizing his dependability, encouraging his enthusiastic reactions, and testing to perceive the amount Macduff’s, and maybe the audience’s, profound quality can at last be undermined. Malcolm depicts Macbeth as a despot, however he positions himself, as well, as somebody ethically terrible. [4] He portrays his own voluptuousnessâ€the unlim ited â€Å"cistern of [his] lust† (4. 3. 4)â€and â€Å"staunchless avarice† (4. 3. 79). Macduff must choose whether he can acknowledge Malcolm as an option in contrast to Macbeth. He doesn't offer this response until the last scene, tending to Malcolm, â€Å"Hail King† (5. 6. 20). By this point, be that as it may, Malcolm has â€Å"abjure[d]/The spoils and accuses I laid upon myself,/For aliens to my nature†(4. 3. 125-127). This shows as opposed to talking honestly about himself, Malcolm was essentially trying Macduff to see where Macduff's loyalties were. Subsequently, Macduff is directly in tolerating Malcolm Macduff (Macbeth) as lord. Macduff may likewise be perused as a forerunner for moral way of thinking. 5] Macduff's departure from Scotland is a â€Å"spiritual reawakening†, with otherworldliness based around reality, paying little mind to what it might be. Macduff continually reevaluates his qualities. In choosing to leave his family, Ma cduff deserts those qualities and pays harshly for it. Macduff echoes suppositions of authors, for example, Plato and the later Thomas Hobbes, who guarantee that ethical quality may just be decided to the degree that an individual assumes liability for their activities. Along these lines, since he acknowledges the weight of his choice to leave his family for political investigation, Macduff's activities can be defended. [5] 3 Macbeth and the dream of female powerOne of the topics that the play Macbeth grapples with is the connection between male defenselessness and ladylike impact. The play investigates the dream of a female or maternal force just as the craving of a break from this impact. [6] Femaleness is to be dreaded and chided, and partly, the play attempts to extract gentility and reestablish self-governing male or fatherly force. In any case, the play additionally uncovered the inconceivability of the dream of total manliness. After Macbeth infers a lot of his inspiration fr om the Witches’ saw guarantee of strength: that no man conceived of lady can execute him.He deciphers the prediction to mean he is untainted by womanliness, as though gentility were the wellspring of defenselessness. [6] Macbeth has faith in his own insusceptibility, asserting, â€Å"I bear an enchanted life, which must not yield/To one of lady born† (Act V, scene 8). In any case, Macduff, conceived by means of caesarian segment, uncovered this dream as a false notion. He answers to Macbeth: â€Å"Despair thy fascinate,/And let the holy messenger whom thou still hast served/Tell thee, Macduff was from his motherâ�

Blog Archive How to Take Ownership of Your Post-MBA Goals and Show They Are Attainable

Blog Archive How to Take Ownership of Your Post-MBA Goals and Show They Are Attainable When admissions officers read your MBA application, they want to feel inspired by your personal statement; they want to know that you have a strong sense of purpose and will work energetically to attain your objectives. Thus, you must ensure that you are not presenting generic or shallow goals. Although this problem is not industry specific, it occurs most often with candidates who propose careers in investment banking or consulting but do not have a true understanding of what these positions entail. For example, a candidate cannot merely state the following goal: “In the short term, when I graduate from Wharton, I want to become an investment banking associate. After three years, I will be promoted to vice president, and then in the long term, I will become a managing director.” This hypothetical candidate does not express any passion for his/her proposed course, does not show any understanding of the demands of the positions, and does not explain the value he/she could bring to the firm. To avoid these kinds of shortcomings, conduct this simple test when writing your personal statement: if you can easily substitute another job title into your career goals and the sentence still makes perfect sense (for example, “In the short term, when I graduate from Wharton, I want to become a  consultant. After three years, I will be promoted to vice president, and then in the long term, I will become a managing director.”), you know you have a serious problem on your hands and need to put more work into your essay. To effectively convey your goals, you need to truly  own  them. This means personalizing them, determining and presenting why you expect to be a success in the proposed position, and explaining why an opportunity exists for you to contribute. For example, a former forestry engineer could make a strong argument for joining an environmental impact consulting firm. (Note: This candidate would still need to explain why he/she would  want  to join one.) Similarly, a financial analyst in the corporate finance department at Yahoo! could connect his/her goals to tech investment banking. Although the connection need not be so direct, especially for candidates seeking to change careers, relating your past experiences and/or your skills to your future path is still extremely important. This approach will add depth to your essay and ensure that the admissions committee takes you seriously. While some candidates struggle to effectively convey their post-MBA goals, many also have difficulty defining their long-term goals. Although short-term goals should be relatively specific, long-term goals can be broad and ambitious. Regardless of what your short- and long-term aspirations actually are, what is most important is presenting a clear “cause and effect” relationship between them. The admissions committee will have difficulty buying into a long-term goal that lacks grounding. However, do not interpret this to mean that you must declare your interest in an industry and then assert that you will stay in it for your entire career. You can present any career path that excites youâ€"again, as long as you also demonstrate a logical path to achieving your goals.

Analyzing Jonathan Swifts A Modest Proposal A...

Jonathan Swifts A Modest Proposal can be said to have a satirical surprise ending, even though the reader is well prepared for it based on the tone and style of Swifts writing and any prior knowledge of the authors intentions. Swifts final solution to the problem of overpopulation is for the poor to sell their children as food for the rich. He introduces this proposition quite early into the document A Modest Proposal, which is why the ending is not so much as a surprise as it is an intriguing rhetorical argument. The reason why the ending might seem surprising is that it seems as if Swift may indeed be presenting a realistic argument of what can be done about overpopulation, in spite of all evidence to the contrary. A reader not used to inferring messages based on tone or style might be forgiven to misread the beginning of Swifts document. For example, a person who has never heard a sarcastic tone could very well believe that Swift was being serious; in which case the reader would c ontinue to view Swifts proposal as reasonable and either consider him a monster or a genius. Generally, Swift uses the surprise ending to alert the readers to the absurdity of the original problem that reveals social injustices and inequities. One of the biggest surprises in Swifts document is when he states, I can think of no one objection, that will possibly be raised against this proposal, unless it should be urged, that the number of people will be thereby much lessened in the

Racism of Yesterday and Today Essay - 1655 Words

The Adventures of Huckleberry Finn was written by Mark Twain in the middle of the nineteenth century. Much of the inspiration for the book came from Mark Twain’s own encounters. Twain’s experiences as a steamboat pilot from 1835 to 1845 provided a great deal of the historical context for his work. The novel revolves around a southern boy, Huck, and a slave named Jim who both reject society by running away in hopes of finding freedom. The Adventures of Huckleberry Finn highlights and portrays the cruelty of racism that surrounded the south in Pre-Civil War America; the racism depicted in the book still to this day receives uproar of controversy and criticism.

An Autobiography Of My Cultural Identity - 1687 Words

I was born and raised in the Dominican Republic. My family was catholic and so I was taught to pray and by the age of 13 I had all my sacraments. For most of my life I lived the downtown area of the main city where my mother and her family had also grown up. I considered myself very lucky because even though our economic security was not the best as I grew up, my mother always strived for me to receive the best education she could afford. As a result, I learned to speak English from a very young age and then French, I learned to play the guitar and also to paint. I also took embroidery and etiquette classes and so on. Because of the location where we lived, I also took advantage of many cultural interactions with people from other†¦show more content†¦Then, I was born in 1989, her only child. Arguably, this story was an eye opener for me from an early age. I wondered, why wasn’t my uncle forced to stop his life and take care of his parents as well, after all they wer e both their children. Instead, my mother the female was the one who quit everything and took care of her parents. As a result I grew up thinking that gender roles were meant to favor men only, while women had to sacrifice their lives for others. Arguably, my mother is my role mother. As a single mother, she struggled to provide for me in unimaginable ways. Being a woman and a single mother in the Dominican Republic played an important factor on her decay in class and economic status. As a result, it created a sense of awareness for me, to understand that as women we have to work twice as hard than men to accomplish half of what they have. This statement was true not only in the Dominican Republic in the 90’s but also today in America. Looking back at my mother’s struggles I cannot say that I have overcome half as much as she did. However, I can see how being a woman has been a disadvantage and an advantage at times. A disadvantage because as women in my society, we tend to be victims of sexism and harassment. Yet, it may also be an advantage because the same society that subject’s women, at times favors these in the labor market.

Zinc Reacts with Vinegar free essay sample

This research is about the chemical reaction of zinc with acetic acid to produce a short amount of electricity. Even though it only conducts a small amount of voltage, we investigated and experimented on how it can produce more than usual without adding any other components on the project except zinc, copper, vinegar, or a unique container that can increase the voltage of our product. The zinc can produce electricity because of the chemical reaction it occurs when it is soaked in vinegar’s acetic acid, the zinc is dissolved to produce hydrogen gas; while the copper’s use is only to move the electrons throughout the entire circuit and connect it to the battery powered object. The main idea we took on our research and personal experiences is that when more batteries are connected, more voltage are produced. Our design is to connect one container of vinegar, zinc, and copper to another container with the same materials to produce our needed voltage. If ever we had reached it, the starting copper wire and the last copper wire will be the wire connected to our LED bulb to light it up and hopefully to let other battery-powered objects to run with this kind of battery. In our results, we were able to light up our LED bulb with an amount of approximately 4. 25 volts while using a 12 slot ice cube tray. We found out that the way to increase the voltage of our product was to have more containers to be connected to each other. i Acknowledgements The researchers extend their gratitude to our Parents for the overall support and help, especially finding the materials needed for our research. To Ms. Michelle Baldevarona for giving us the chance to work on this project and made corrections on our mistakes And most importantly, to God, our Father, for the knowledge, strength, time, and life He gave to us to make this research a success. ii Table of Contents TitlePage A.

Appendices18 Chapter 1 Introduction Background of the Study The researchers first aimed to find a good project that can conduct even a short amount of electricity through their own simple chemical reaction. We then came upon with zinc’s reaction with acetic acid. In our research it produces a very short amount of voltage. We want to find a way to strengthen the production of electricity without using other components to help us with our task except zinc, copper, vinegar and either a glass or plastic container. If we indeed improve it, would it light an LED bulb, and how much voltage it produces? After agreeing with the said product, we then studied on battery cells. The electric current involved in this research is called electrochemical cells; these cells are used to store chemical energy to eventually move electrons. The more the cells, the stronger the voltage it produces. The electrons can move through the whole circuit by using the copper wire as a connecting wire and be able to light up our LED bulb. Lastly, in our early research, more than one cell is then called a battery. 1 Statement of the Problem This study aims to determine if the chemical reaction of zinc with acetic acid can produce electricity and if ever, how can it produce more. We aim to answer the following questions: 1. How can zinc and acetic acid produce more electric voltage? 2. Is it enough to light an LED bulb? 3. How many containers that it takes to light the LED bulb? Formulation of the Hypothesis The researchers hypothesized that we wouldn’t fully lit the LED bulb but only to light it up due to the low voltage it produces. 2 Significance of the Study We opt to understand the chemical reaction of zinc on acetic acid and learn its balanced equation. And on further testing, we want to use this to take advantage on saving batteries for other uses. Through this study, the researchers hoped to help and teach the following people. a. House owners – House owners always want to save electricity, this can be a substitute on objects that only need small amount of voltage to run. And with simple materials, they can understand and learn how electric current move and work. b. Students on Chemistry Class – The chemical reaction can help them with their studies even though it’s just simple. It can let them understand how chemical reaction important on our daily life because it is everywhere. c. Scientists – Zinc’s reaction on acetic acid produces hydrogen gas in a form of a bubble; scientists can study on producing this gas to enhance our knowledge on the most abundant element on the universe. d. Electric Engineer – They might want to expound the idea of this study and try to reduce it to the size of an AA battery. 3 Scope and Limitations The research took awhile because we are trying to understand how the electrons from one cell move and adds up the voltage, and while we tried it out, we had a hard time fixing up the wires and finding the right container. We then found valuable information from the Internet through tons of searching and reading. Most of the information went from people’s opinion on how the battery works. And we read that the zinc slowly dissolves on vinegar, so the battery might not last long unless you change the zinc afterwards. While the purpose of our study was to understand the chemical reaction of zinc with acetic acid on producing our needed voltage to light the LED bulb. Definition of Terms Vinegar is a liquid consisting mainly of acetic acid (CH3COOH) and water. The acetic acid is produced by the fermentation of ethanol by acetic acid bacteria. Zinc is a metallic chemical element; it has the symbol Zn and atomic number 30. It is the first element of group 12 of the periodic table. Zinc is, in some respects, chemically similar to magnesium, because its ion is of similar size and its only common oxidation state is +2. Copper is a chemical element with the symbol Cu and atomic number 29. It is a ductile metal with very high thermal and electrical conductivity. 4 Acetic Acid is an organic compound with the chemical formula CH3COOH. It is a colorless liquid that when undiluted is also called glacial acetic acid. Vinegar is roughly 4%-8% of [acetic acid] by volume, making it the main component of vinegar, apart from water. H3O+ (Hydronium Cation) is the positively charged polyatomic ion with the chemical formula H3O+. Hydronium, a type of oxonium ion, is formed by the protonation of water (H2O). OH- (Hydroxide) consists of oxygen and a hydrogen atom held together by a covalent bond, and carries a negative electric charge. It is an important but usually minor constituent of water. It functions as a base, a ligand, a nucleophile and a catalyst. Weak Acid is an acid that dissociates incompletely, releasing only some of its hydrogen atoms into the solution. Thus, it is less capable than a strong acid of donating protons. Cation an ion with fewer electrons than protons, giving it a positive charge. Anion is an ion with more electrons than protons, giving it a net negative charge. Battery – is a device that produces electricity by a chemical reaction between two substances. 5 Electrochemistry a branch of chemistry that studies chemical reactions which take place in a solution at the interface of an electron conductor and an ionic conductor. These reactions involve electron transfer between the electrode and the electrolyte or species in solution. Electrochemical cell a device capable of either deriving electrical energy from chemical reactions or facilitating chemical reactions through the introduction of electrical energy. 6 Chapter 2 Review of Related Literature and Studies Zinc’s Reaction with Acetic Acid The composition of U. S. pennies was changed in 1982. For the preceding 20 years, pennies were an alloy of about 94 % copper and 6 % zinc. The increasing cost of copper made this impractical. Therefore, some 1982 pennies, and all pennies produced after that time, have a pure copper shell with a zinc interior. The new pennies contain only about 2. 4 % copper, and weigh about 2. 5 grams, as opposed to the approximate 3. 1 gram weight of the older type. Zinc is a more reactive metal than copper. In this experiment, you will show that zinc will react with vinegar (an acetic acid solution) to produce hydrogen gas, while copper will not react. Vinegar is a 5 % solution of acetic acid. It is not a very strong acid, nor is it very concentrated. For this reason, the reaction proceeds fairly slowly. The hydrogen gas generated by the reaction bubbles up, because it is less dense than the Penny and the acid solution. 7 However, toward the end of the reaction, some bubbles of hydrogen may adhere to the copper or be trapped inside the shell. If this occurs, the combination of copper and hydrogen gas may be less dense than the acid solution, and what’s left of the penny may actually float.

A simple electrochemical cell can be made from copper and zinc metals with solutions of their sulfates. In the process of the reaction, electrons can be transferred from the zinc to the copper through an electrically conducting path as a useful electric current. An electrochemical cell can be created by placing metallic electrodes into an electrolyte where a chemical reaction either uses or generates an electric current. Electrochemical cells which generate an electric current are called voltaic cells or galvanic cells, and common batteries consist of one or more such cells. In other electrochemical cells an externally supplied electric current is used to drive a chemical reaction which would not occur spontaneously. Such cells are called electrolytic cells.

Free electrons are also known as conduction electrons. Each copper atom provides a single free electron, so there are as many free electrons as atoms. Free electron concentration in copper n = 8. 5 ? 1028 per m3 When a voltage is connected across a piece of copper, it pushes the free electrons so that they flow through the metal – thats an electric current. Notice that the electrons start to flow as soon as the switch is closed. The message to get them moving is instantaneous (in fact it travels close to the speed of light). However, the electrons themselves travel much more slowly. So how does the current come on everywhere as soon as the switch is closed? It is because the free electrons are already spread through the wire. As soon as the switch is closed, there is a force on all the electrons, which gets them moving. Its a bit like a bicycle chain. As soon as you start pedalling, the back wheel starts to turn. The force on the back wheel is instantaneous even though the individual links are travelling at a visible speed. But because the links are already spread around the chain circuit they all start to move at the same time.

It is often referred to as electric potential, which then must be distinguished from electric potential energy by noting that the potential is a per-unit-charge quantity. Like mechanical potential energy, the zero of potential can be chosen at any point, so the difference in voltage is the quantity which is physically meaningful. The difference in voltage measured when moving from point A to point B is equal to the work which would have to be done, per unit charge, against the electric field to move the charge from A to B.

Fill up any number of containers with vinegar. A copper wire on the start of one container, will be either the positive or negative side of the battery, then zinc connected with a connecting wire connects the two containers, the zinc is on the first container then connects the second container with the connecting wire. Repeat on to connect more cells and to produce higher voltage. Then end with zinc connected with a copper wire while the zinc is soaked on the vinegar and the copper wire is dry outside. Materials Needed Vinegar-LED bulb Containers-Battery Tester Zinc Strips/Nails Copper Strips Connecting Wires 12 Procedure Setting Up: 1. Took some containers and fill them up with vinegar. 2. Took one copper wire and placed hanging on the very first container on any side of the platform. 3. Connected a zinc metal with a connecting wire and soaked the zinc on the first container and the connecting wire on the second container. 4. Continued placing zinc and connecting wire on the second to third container 5. Repeated on until all the containers are connected 6. Placed the last zinc connected with a copper wire on the container (Zinc soaked, Copper wire left hanging outside) Testing the Battery 1. Took out our battery tester and checked the voltage of the battery by touching both copper wires with the respective testing wires. 2. Connected the LED light bulb on the two respective copper wires. 13 Chapter 4 Presentation, Analysis and Interpretation of Data Presentation of Data, Analysis and Interpretation of Data Table 1: The researchers want to obtain enough voltage to light up an LED bulb; we started from a trial test with glasses and try to work it with a number of containers to obtain our needed, stronger voltage. Trial with Number of Containers Connected Voltage Produced What Happened? LED Bulb? Trial 1 Glass Connected 2 ~0. 90 The researchers’ first attempt to produce electricity, Voltage was too low. No Trial 2 Glass Connected 4 ~1. 55 With 4 Glasses connected to each other, voltage went a little bit higher. No Trial 3 Glass Connected 5 ~2. 20 Same happened with 5 Glasses. No Trial 4 – Ice Cube Tray (small) Connected 12 ~4. 25 We changed our container to an ice cube tray having 12 small slots. Voltage was astonishing and it lit up our LED bulb. Yes 14 Findings The researchers found out that to obtain the needed voltage, we need to have more containers connected to each other because the electrons has to move around, and when it moves, it is reaching more vinegar, more acetic acid therefore producing higher voltage. Results In the results, when more containers are being connected to one another, the higher voltage it produces. But until we had the light bulb to light up we connected 12 small container of an ice cube tray to each other. It didn’t take that much space compared the trial where we used glasses as our container. So on our opinion, the volume of vinegar doesn’t matter as long as we connect more containers to one another, and it produces higher voltage. 15 Chapter 5 Summary, Conclusions, and Recommendations Summary The research claims that indeed the zinc can produce electricity when reacted with acetic acid. The way to light up the LED bulb is to connect more containers to one other because the electrons move on each container until it reached the object to be powered. The LED bulb was lit due to a correct amount of containers that will produce enough voltage to light it up. Conclusion So we concluded that acetic acid and zinc can conduct electricity but to produce more means to add more cells just like a simple battery, the more that there are connected the more electricity it produces. We were able to light up an LED bulb with 12 small containers of an ice cube tray, each slot with zinc and copper wire soaked on the vinegar. But the battery wouldn’t last long because of the dissolving of zinc to the acid, but replacing it is easy and won’t take a lot of time. 16 Recommendations We recommend using a container that can supply already more than 5 slots for setting up your battery, just like an ice cube tray that we used. Because if continued with a lot of glasses or large containers, it will take more space than usual. And also, we recommend fixing your wire properly because ours’ look messy. And lastly, if you want to run some things that takes a higher voltage to run, you may want to spend your time on connecting a lot of ice cube tray to one another with the same procedure. 17 Appendices A.

Ballistics Essays

Ballistics Essays Ballistics Essay Ballistics Essay Paper Ballistics Bullets traveling over two thousand feet per second and having more energy than one normal person can perceive. Can you imagine tracking where, how, when, and what from angle this bullet was shot. Ballistic scientists can. Ballistics is the study of any projectile used as a weapon. This can certainly make or break a case Involving a guru Great ballistic scientists can even provide how far the bullet was shot from before It makes contact with the target. To me this is one of the most Important tools in a case where a firearm is used. The definition of ballistics is very simple, the study of projectiles from a weapon, mainly referring to bullets out of a gun. That Is a dulled down definition. My definition is a little lengthier in depth. Forensic ballistics includes the examination of bullets and firearms in an attempt to identify particular weapons used at any particular time. Guns and bullets leave small signs behind when fired, which professional ballistic scientists can pick apart and define what gun, bullet, energy, and even charge of the casing. This makes ballistic scientist one of the most important keys on a law enforcement agency. Pistols and rifles are categorized by what the inside diameter of the barrel measures. This is called caliber. An example would be, a 22 caliber rifle has a much smaller diameter barrel than a . 370 caliber rifle does. In turn, the bullet of a . 22 caliber is going to be considerably smaller than that off . 370 caliber, Pistols are categorized the same way. A . 40 caliber is much smaller than a . 460 caliber. Shotguns, however, are not categorized Like this. Shotguns are categorized by gauge. Unlike the rifle, the smaller the gauge of a rifle the bigger the inside diameter is. Such as, a twelve gauge has a much larger barrel than a twenty-eight gauge. Now that I have explained sizes and categorization to the guns, next Is the operation of the guns. When a gun is fired it takes many parts to make the gun fire and also for the bullet to hit Its target. When you pull the trigger on a gun, the firing pin strikes the bullet to set tot the gunpowder. That leaves a mark on the casing as unique as a fingerprintno two guns strike the bullet in exactly the same way. Furthermore, the barrels of every gun are rifled, which means they contain grooves, wanly Nell ten Dulled spun Ana make It more accurate. In turn, ten Dulled NAS ten marks from the rifling in the barrel, which can be matched up to the weapon that fired it. There is one exception to the rifling in the barrel. That exception is smooth bore shot guns. They are smooth, Just like the name implies. Now to talk about the term most people deem as ballistics, the speed, drop, and energy off bullet. Charge, weight, and muzzle length are three things that affect the speed and drop off bullet. Something most people don?wet know is that a bullet does not shoot straight horizontally. When I bullet is shot it is shot at a raising angle. Which means the bullet breaks the plane of the muzzle once before hitting the target. A . 22 caliber rifle breaks the plane of the muzzle at twenty-five yards, if the rifle is zeroed at 100 yards. Not all rifles cartridges cross at these measurements. That all depends on the weight, charge, and velocity of the bullet. Weight can also be described as knock-down power. A high caliber rifle will shoot heavier bullets and have more knock-down power. The more weight means that there is more kinetic energy. For example, a . 357 caliber rifle shoots a lighter, much faster bullet than that off . 5 caliber. Although the . 57 is faster and more flat shooting, the . 45 caliber has more knock-down power because of the weight of the bullet and the kinetic energy. Although this information is more helpful too hunter, it is useful to any shooter. Charge is described as the amount of black-powder used to fire the bullet. The more the charge, the bigger the bang. Every gun uses black-powder to be fir ed. Black-powder was the first explosive, and used in every gun in the history of fire- arms. From the oldest muskmelons to the most high tech sniper rifles used today. Now that the velocity of the gun is covered, next will be to explain what happens o the bullet once it hits the target. There are many different types of bullets. Such as soft tip, hollow point, and wad cutters. There are also a few types of hollow points. Hollow points are bullets that expand, (or mushroom) once they have impacted the target. These are most common and also the most harmful. Not only do you have a bullet traveling at over 1 500 feet per second, but they also expand and leave gaping entry and exit wounds, and can also leave trace amounts of the bullet inside the target. One type of hollow point is a slow expanding bullet. It works exactly like it is babbled, it is a harder bullet that still expands, but may not fully expand until it is very far into the target. These do a lot of damage, but not as bad as a fast expanding bullet. Fast expanding bullets expand as soon as contact is made with the target and is the most lethal type of bullet. Because they open so quickly you get the mushroom effect completely through the target. Wad cutters are nothing more than a solid piece of lead. They are mainly used for target practice because they are very cheap and do not have the charge nor the velocity of a hunting load. Although they arena t as powerful they are Just as harmful. Since they do not expand they stay a solid completely through the target and also after if there is an exit wound. These are Just as deadly because they can ricochet inside off target such as a human. Wad cutters are used in a lot of gang fights because they will not kill someone, but they will penetrate the skin and once inside the person they will ricochet off of the ribs and sternum, doing much internal damage. On each and every gun manufactured, there is a serial number stamped into it. It Is made Day pressing ten metal so even Day Telling Tontine serial under Trot ten inside, the scientist can still use ultra-sound to find out the serial number. Filing off serial number is a crime in itself and is very common in gangs, drugs, and acts of violence. By acquiring this serial number ballistic scientists can find out the caliber, make, model, store it was sold from, and even the owner. This is a huge factor in ballistic science. If you can place a gun with an owner/operator, as a ballistic scientist you have won half the battle of solving the crime. Ballistic scientists not only work with the operation of the gun, but also the distance and angle the bullet was shot from. For instance, the entry hole on a target well be much smaller than the exit hole because of the expansion of the bullet and the velocity that it exited at. In this case if you can determine and entry and exit wound you can tell what angle the bullet was shot from and determine the vicinity that the shooter was when the bullet was fired from the firearm. Distance is a huge key to figuring out what happened at a crime scene. A bullet fired from point-blank range out to a very close range will leave a black-powder burn on the target. A shot a point-blank range will have a tighter more distinct burn than en of a shot from a further distance. Another determining key to distance is penetration. If a bullet has not completely passed through a victim it could have been fired from a farther distance than what the proprieties of the scene allow. Some of the tests and examinations of ballistics include a few different types of test shooting. The ballistic scientist will test shoot the gun to find out its markings and striations on certain types of bullets to try and match a bullet with a gun and even a gun with an owner. That type of test can obviously only be done if either remains of the bullet or the gun is found. If neither the gun nor bullet is found at the scene the scientist can shoot different types of guns into what is called ballistic gel. This gel is comparable to the skin, muscle, and fat off human. It is a clear gel so you can compare the wound channel of the victim to that of the gel. This is also helpful with studying expansion of a bullet considering the gel is clear. Collecting evidence from a crime scene is very important. You do not want to hurt any evidence that could hinder the case. When collecting evidence such as a gun, never place a pencil inside of the barrel or trigger guard. Not only is that not proper rearm safety it is also harmful to any evidence that is located there. The firearms can be picked up by the textured part of the grip, while of course wearing rubber gloves to leave no extra fingerprints behind. Before picking up the firearm, make sure it is pointing in a safe direction. Most criminals do not unload the firearm before they drop it at a crime scene. Keep notes on the condition of the gun, the location, and time it was found. These call all be key factors in telling when, where, why, and how the victim was shot. If the barrel is damaged in any way, it will affect the outcome of test shooting. The same goes for the firing mechanism. The firearm should be contained in either a large envelope or a paper bag. It should be kept separate from the bullets, casing, or magazine. Putting all of these pieces of evidence in one container can lead to scratching and damaging any piece of evidence. As for collecting the bullet or casing from a scene, you must be very careful and collect it right or it will be no good as evidence. Since casings and bullets are metal, IT tenure Is any metal on metal contact ten specimen can De rule Ana scratches. This is why you would want to collect the evidence by hand with gloves on. Also one thing that most criminals don?wet think about is when you are loading your weapon you are leaving your fingerprints on the casings as you load them into the magazine. This is why casing are very important to any case. You would not want to use metal tweezers. If the bullet is scratched it could lead to false reading in test shooting or examination. Bullets and casings should be placed in a separate small cardboard box or a small envelope at the least. When collecting a magazine you should take the same precautions as you do with the gun, bullets, and casings. The magazine can be a very important part of the rime scene. Let?was possible that the magazine that was left behind could still have cartridges in them that have not been fired. If so that could narrow down the search for the caliber of gun and also the type of ammunition that was shot. Also with finding the magazine you can examine it for fingerprints from when the magazine was loaded and unloaded. With finding such things as the magazine, bullets, and casing you can determine many things such as, position, distance, caliber, gun, and even an escape route if the magazine was dropped. When I had first chosen the topic ballistics I thought I would be more focused on he science part of ballistics. But once I researched and put some of my own knowledge to work I realized that I was more interested in the way guns work and the way bullets travel. Although I don?wet see myself as the laboratory type, if I could only work on firearms cases it would not be that bad of a Job. I know as a student I learned very much in my research of bullets, guns, and ballistics. ?catheter are hundreds of millions of gun owners in this country, and not one of them will have an accident today. The only misuse of guns comes in environments where there are drugs, alcohol, bad parents, and undisciplined children.

Casting and Data Type Conversions in VB.NET

Casting and Data Type Conversions in VB.NET Casting is the process of converting one data type to another, for example, from an Integer type to a String type. Some operations in VB.NET require specific data types to work. Casting creates the type you need. The first article in this two-part series, Casting and Data Type Conversions in VB.NET, introduces casting. This article describes the three operators you can use to cast in VB.NET - DirectCast, CType and TryCast - and compares their performance. Performance is one of the big differences between the three casting operators according to Microsoft and other articles. For example, Microsoft is usually careful to warn that, DirectCast ... can provide somewhat better performance than CType when converting to and from data type Object. (Emphasis added.) I decided to write some code to check. But first a word of caution. Dan Appleman, one of the founders of the technical book publisher Apress and a reliable technical guru, once told me that benchmarking performance is much harder to do correctly than most people realize. There are factors like machine performance, other processes that might be running in parallel, optimization like memory caching or compiler optimization, and errors in your assumptions about what the code is actually doing. In these benchmarks, I have tried to eliminate apples and oranges comparison errors and all tests have been run with the release build. But there still might be errors in these results. If you notice any, please let me know. The three casting operators are: DirectCastCTypeTryCast In practical fact, you will usually find that the requirements of your application will determine which operator you use. DirectCast and TryCast have very narrow requirements. When you use DirectCast, the type must already be known. Although the code ... theString DirectCast(theObject, String) ... will compile successfully if theObject isnt a string already, then the code will throw a runtime exception. TryCast is even more restrictive because it wont work at all on value types such as Integer. (String is a reference type. For more on value types and reference types, see the first article in this series.) This code ... theInteger TryCast(theObject, Integer) ... wont even compile. TryCast is useful when youre not sure what type of object youre working with. Rather than throwing an error like DirectCast, TryCast just returns Nothing. The normal practice is to test for Nothing after executing TryCast. Only CType (and the other Convert operators like CInt and CBool) will convert types that dont have an inheritance relationship such as an Integer to a String: Dim theString As String 1 Dim theInteger As Integer theInteger CType(theString, Integer) This works because CType uses helper functions that arent part of the .NET CLR (Common Language Runtime) to perform these conversions. But remember that CType will also throw an exception if theString doesnt contain something that can be converted to an Integer. If theres a possibility that the string isnt an integer like this ... Dim theString As String George ... then no casting operator will work. Even TryCast wont work with Integer because its a value type. In a case like this, you would have to use validity checking, such as the TypeOf operator, to check your data before trying to cast it. Microsofts documentation for DirectCast specifically mentions casting with an Object type so thats what I used in my first performance test. Testing begins on the next page! DirectCast will usually use an Object type, so thats what I used in my first performance test. To include TryCast in the test, I also included an If block since nearly all programs that use TryCast will have one. In this case, however, it will never be executed. Heres the code that compares all three when casting an Object to a String: Dim theTime As New Stopwatch() Dim theString As String Dim theObject As Object An Object Dim theIterations As Integer CInt(Iterations.Text) * 1000000 DirectCast Test theTime.Start() For i 0 To theIterations theString DirectCast(theObject, String) Next theTime.Stop() DirectCastTime.Text theTime.ElapsedMilliseconds.ToString CType Test theTime.Restart() For i As Integer 0 To theIterations theString CType(theObject, String) Next theTime.Stop() CTypeTime.Text theTime.ElapsedMilliseconds.ToString TryCast Test theTime.Restart() For i As Integer 0 To theIterations theString TryCast(theObject, String) If theString Is Nothing Then MsgBox(This should never display) End If Next theTime.Stop() TryCastTime.Text theTime.ElapsedMilliseconds.ToString This initial test seems to show that Microsoft is right on target. Heres the result. (Experiments with larger and smaller numbers of iterations as well as repeated tests under different conditions didnt show any significant differences from this result.) Click Here to display the illustration DirectCast and TryCast were similar at 323 and 356 milliseconds, but CType took over three times as much time at 1018 milliseconds. When casting reference types like this, you pay for the flexibility of CType in performance. But does it always work this way? The Microsoft example in their page for DirectCast is mainly useful for telling you what wont work using DirectCast, not what will. Heres the Microsoft example: Dim q As Object 2.37 Dim i As Integer CType(q, Integer) The following conversion fails at run time Dim j As Integer DirectCast(q, Integer) Dim f As New System.Windows.Forms.Form Dim c As System.Windows.Forms.Control The following conversion succeeds. c DirectCast(f, System.Windows.Forms.Control) In other words, you cant use DirectCast (or TryCast, although they dont mention it here) to cast an Object type to an Integer type, but you can use DirectCast to cast a Form type to a Control type. Lets check the performance of Microsofts example of what will work with DirectCast. Using the same code template shown above, substitute ... c DirectCast(f, System.Windows.Forms.Control) ... into the code along with similar substitutions for CType and TryCast. The results are a little surprising. Click Here to display the illustration DirectCast was actually the slowest of the three choices at 145 milliseconds. CType is just a little quicker at 127 milliseconds but TryCast, including an If block, is the quickest at 77 milliseconds. I also tried writing my own objects: Class ParentClass ... End Class Class ChildClass Inherits ParentClass ... End Class I got similar results. It appears that if youre not casting an Object type, youre better off not using DirectCast.

Capitalism at its best Essay Example | Topics and Well Written Essays - 500 words

Capitalism at its best - Essay Example Once the insurance policies are cashed in, they are set to be invested in by a third party. This party continues to pay the required insurance policy premiums for the policy that he/she invests in. In so doing, the original beneficiary of the insurance policy gets to utilize his/her resources before death come knocking. On the other hand, the viatical settlement company profits from such operations by getting a percentage face value of the policy transacted under viatical settlement. After the original insurance policy holder dies, the settlement company or the third party that invests in the cashed in policy becomes the beneficiary. From the cashing in of the insurance policy to the sale of that policy to a third party, all the transactions involved are privately undertaken. On the same note, viatical settlement companies are private entities that operate alongside other private players in the economy setting. As a result, viatical settlement companies exhibit private ownership of resources, and consequently capital in their operations. These factors are the most critical when it comes to the definition of capitalism. Capitalism continues to be portrayed at its best in respect to the risks that viatical settlement companies take in allowing terminally ill patients to cash in their insurance policies. Viatical settlement practices are highly complex and critically prone to ethical issues Accountability is a critical factor to account for in the process of undertaking viatical settlements. The legal system regulates and governs viatical settlement transactions, thereby allowing players in that market to coexist and engage in healthy competition. The competition factor in viatical settlements further presents the capitalism aspect. Viatical settlement companies are not immune to the legal provisions that streamline business operations. Failure to comply with the set laws results in legal actions against the

The Function of Management Planning Essay Example | Topics and Well Written Essays - 1500 words

The Function of Management Planning - Essay Example Within this organization, the planning involved selecting enterprise goals and department objectives than finding ways of achieving them. Plans depended upon the existence of alternatives, and then decisions had to be made regarding what to do, how to do it, when to do it and by whom it is to be done. Author Anderson has a responsibility to meet society's expectations in three concentric circles of responsibility (Arthur Andersen, 2007). The inner circle includes the business's clear economic responsibilities such as quality and safety and the provision of jobs and services. The intermediate circle expands the responsibility of businesses to make their policies and practices consistent with societal values in such matters as fair employment practices and a benign environmental impact (Accounting Industry, n.d.). The nature of ethical standards is one of the key issues to be addressed by personnel managers operating in a large corporation. There will gradually be a growing together of national practice on working hours, but it will take a lot longer for rates of pay to harmonies. Arthur Anderson adopts CSR because some moral justification comes from a value system that is independent of the business itself and where individual opinion can be sharply divided. SCR implies that employees at work should be honest and that claims about a product or service should be accurate. Ethical issues are corporate behavior and fair competition. In order to meet these objectives, Arthur Anderson uses systematic planning. Fair competition is achieved by adoption of specific ethical rules which guides management and marketing policies. Risk and uncertainty are minimized by planning and this is needed more today than before as social and economic conditions alter very quickly and careful planning enables an organization to prepare for change. Planning helps Arthur Anderson to define its purposes and activities according to fair competition rules. It enables performance standards t o be set and results can, therefore, be compared with the standard to enable managers to see how the organization is proceeding towards its goals. Planning is flexible to deal with a changing environment. Corporate behavior means that employees follow established norms combining their own judgment with the benefits of the corporation. In this case, the ethical responsibility of Arthur Anderson is to analyze social conditions and possible threats of their services for potential consumers. They should be well aware of the educational background of their customers and their expectations (Corporate Social Responsibility, 2007). Social responsibility translates into expectations that businesses comply with the spirit of society's laws and with the normative base that undergirds them. The social responsibility issues followed by Author Anderson are the attitude of management to labor and fair reward and use of shareholders capital. The attitude of management to labor is achieved through f air payment schemes and healthy corporate climate, training programs and promotion activities. Arthur Anderson provides additional training focusing on employee's motivation and work design programs to help worker identify their goal and professional development strategies.  

The Napoleonic Era Essay Example for Free

The Napoleonic Era Essay Napoleon’s impact has been so great that an entire historical time period bears his name, the Napoleonic Era. For over a decade, he was to be the master of Europe—but he was also a man. During the Triumvirate and Despotate in 1799 to 1804 CE and 1804 to 1815 CE, respectively, Napoleon made several errors (Rose, 2006). First of all, he suffered greatly due to an impediment at Eylau, Leipzig, Borodino, and the ultimately at Waterloo.   Napoleon’s decision not to establish a treaty with other players such as Austria (in a Paris-Vienna axis) in the balance of power was his first major setback. The treaty could have helped him maintain the power of Britain and simultaneously gain and improve his peripherals and palatinates within Italy. Not only will this improve his power over Italy but also to the Autarchy of Naples, Dutch-Belgian demarcation, the Helvetian Republic and the Piedmont Kingdom. Another mistake that he committed was the two-front war. Napoleon wages war over Russia and Iberian promontory in the year 1807 up to 1814 CE. He even made an error regarding the unity among his troops, which was divided when he appointed four different marshals having different military and social backgrounds. Napoleon also misjudged military activities by the sea, which resulted to a weak line of defense, or no defense at all, from the Mediterranean up to the Atlantic (Coakley, 1992). Second, with regards to economic warfare, Napoleon’s Berlin Blockade, then modified to Continental Blockade, ultimately produced negative effects or results for France, exciting dissidence and unrest. In the east, he failed with a tripartite incursion of the Swedish throne. He also failed with the Ottoman Empire’s symmachia that was directed to Russia. As a result, the attention of Russia was brought upon Napoleon’s intentions, putting him near the edge of winning. Lastly, Napoleon miscalculated the size of the phalanxes at the Russian Campaign (Stocqueler, 1852). This eventually rendered him unable to gain victory over Russia. In the end, all of Napoleon’s mistakes are the fruit of his unwavering ego. References Coakley, T. P. (1992). Command and Control for War and Peace: Diane Publishing Company. Rose, J. H. (2006).

The Appalachian Trail :: essays research papers

When I was in the seventh grade, our class went on a field trip to Cherokee, North Carolina. The trip lasted four days and three nights, but the adventure would last a lifetime. The experience allowed me to learn many things about myself and to reflect on the beauty that was all around me. We departed at six-thirty in the morning, and I was so excited. I had never been away on a school trip for longer than a few hours. I tossed my purple duffel bag into the storage compartment, found my seat by the window, and prepared for what I knew would surely be an unforgettable adventure. When we finally arrived in the mountains, it was breathtaking. They were covered with trees, and the clouds floating over them were so beautiful. I looked down and saw valleys of flowers that went on forever. I was so anxious to get off the bus and roll in the grass with the clear, blue sky above my head. The bus came to a halt, and one by one we filed out into a parking lot. We grabbed our canteens and began the one-mile trail to the top of one of the mountains. I was one of the first people to reach the peak, and waiting for us was a notebook. We opened it to find the names of everyone who has ever reached the peak. I smiled to myself as I wrote in big letters â€Å"Kim Walton† and started back down the mountain. It was much easier and faster than going up, and everyone was really excited to see where we were going next. When we arrived at the Best Western, everyone grabbed his/her suitcases, quickly tucking them into the rooms as the candy shop across the street drew us in like moths to a flame. Afterwards, we went back to our rooms, put on our bathing suits, and went for a late-night swim under the stars. It was so cold, but we did not mind it because we were having so much fun. Later we went back to our rooms and went to sleep. Our next day would surely be packed with action and adventure. The next morning, we went to Alpine Tower: a seventy-five feet high vertical structure that is designed to help you work with others and test your physical strength as well as your bravery, motivation, and problem-solving strategies. Equipped with helmets, harnesses, and ropes, we took our places around the tower and prepared for the first person to go up.

Economic questions Essay

1. It has to do with game theory. In the prisoner’s dilemma, two suspects are taken by the police and each told separately that they can gain their freedom by testifying against each other. If neither testifies, they each will serve a six months sentence. If one testifies the other stays silent, the one will go free and the other will serve 10 yrs. If both testify then both will serve 5 yrs. The best thing is for both to be silent, but the more likely scenario is that each, fearful of a long sentence, bails on the other and nobody wins. In economics it is the investors hoping to ride the high flyers into the New Year; the best outcome is for nobody to sell. Most years, that is how it works and year end rallies leave everyone satisfied. 2. Economic theory. Through regulation is the best way market failure or externalities are dealt with when they are harmful to society. Externality is an economic side effect. They are the costs or benefits that come from economic activities that affect others than the individuals that re engaged in the economic activities. Some solutions are negative- taxes, positive-subsidy. 3. Sources of income in a capitalist economy would be their property rights that entitle them to earn a profit for the use of their capital as risk in some form of economic activity. They would be related through labor by human capital. The knowledge and skill acquired by labor through education and labor. 4. The rate is determined by a percentage of its turnover or sales. 5. Investment is something investors decide how much they will spend on new investment. Example: Producers have to decide whether to replace used up or obsolete machinery, whether to expand production these costs will become an investment that in turn should make them money. There are four principal determinants of autonomous investment, the level of technology, rate of interest, expectation of future economic growth and the rate of capacity utilization. 6. With an equilibrium price. The price that equates quantity demanded to quality supplied. If any disturbance from that price occurs, excess demand or excess supply emerges to drive price back to equilibrium. 7. The classical view of how our economy behaves is this: If the economy were left on its own without the interference of government or the Fed. It would move towards an equilibrium rate of growth that would produce with only minor interruptions, full employment without inflation. This hands off rests upon two simple propositions about market, one that all markets are basically competitive and two, all prices are flexible upward and downward approaching equilibrium. Unemployment is only a temporary condition caused by wage rates climbing above the equilibrium rate. A shift in the extraction curves is the economy’s rate of unemployment and rate of inflation. 8. Supply-side economists emphasize the importance of reducing tax rates. They accept the Keynesian idea that lower tax rates will increase consumer demand, but they believe a more important consequence is the added incentive it provides suppliers. For example; lower corporate tax rates increase after tax profit, which induces suppliers to increase aggregate supply. Lower income tax rates encourage more people to work longer, adding as well to aggregate supply. 9. Savings automatically converts to investment; so that investment induced growth is dependent on saving. 10. The division of labor into specialized activities that allow individuals to be more productive. The idea that labor productivity is a function of the degree of labor specialization. 11. Upward sloping trend cutting through the cycle traces the economy’s output performance over the course of a business cycle, measured either from recession to recession or from prosperity to prosperity. The upward sloping character of the trend line signifies economic growth. 12. Every economy, whatever its level of national income, includes people earning different incomes. Knowing someone’s absolute income tells us little about that person’s income status. 13. Consumption spending is rooted in Status. High income people not only consume more goods and services than others, but also set consumption standards for everyone else. 14. Aggregate supply is the total supply of goods and services that all firms in the national economy are willing to offer at varying price levels. Aggregate demand is the total quantity demanded of these goods and services by households, firms, foreigners, and government at those varying price levels. Macroequilibrium is reach when aggregate supply equals aggregate demand. 15. Consumption spending has tended to be more stable than investment spending in the past. MPC can be counted on to remain pretty much unchanged. Autonomous consumption is hardly likely to change. Investment spending is considered volatile. Economists identify changes in aggregate expenditure as the key to understanding why national income changes. Changes in investment have highly magnified effects on national income. The income by which income changes as a result of a change in aggregate expenditure is called income multiplier. 16. The economy’s output or gross domestic product is the total value, measured in current market prices, of all final goods and services produced in the economy during a given year. 17. One solution is to combine wage and price controls with a Keynesian style job creating policy. Stabilization policy is one option. 18. Four principle factors contributing to a nations economic growth, the size of the labor force, the degree of labor specialization, or the division of labor, the size of its capital stock and the level of its technology. Savings automatically converts to investment; so that investment induced growth is dependent on savings. 19. Demand deposits are only half of a banks business. Loans are the other. The bank makes a profit only on the loans it provides, not on it deposits. Borrowers benefit from inflation where lenders, where as lenders lose money. 20. Through the circular flow model, how the economy’s resources, money, goods and services flow between households and firms through resource and product market. 21. Economies with negative balances on current account will find their exchange rate falling. And unless these rates are propped up by government intervention, they will fall to stem the currency outflows exist; the exchange rate will keep falling. Eventually the rate will reach the level appropriate to a zero balance on current account. It takes only time. He would think we were habitual borrows. 22. They are the â€Å"what is† and â€Å"what it should be† 23. Nothing because the infrastructure is what an economy’s ability for development depends upon. Such as with education to educate people involves not only the task of acquiring compliance but the funds needed to build the school and staff them.
