Essay on Feudalism and Capitalism - 3836 Words
Feudalism and Capitalism Economic processes are those involving the production and distribution of goods and services. However, they do not alone determine this production and distribution. There is an interrelationship of economic, cultural, environmental, and political processes that all help to shape each other. Nothing that we do can be defined as a single process, for it is the interaction itself that helps to produce the final results that we observe. To understand this more fully the following basic definitions may be of use: Cultural Processes are those that involve the creation and transfer of knowledge-the production of meaning. Political processes are those by which we establish and enforce rules, and theyâ⬠¦show more contentâ⬠¦Films are important and useful tools for the analytical process that needs to take place when searching for the answers to the questions. Films are understood to be, among other things, the product of a particular economic theory or set of theories (which can be contradictory), to teach particular theories (including economic theories), and to provide an objective for analysis using economic theory. (Professor Gabriel) It is with this in mind that the films of Matewan and Norma Rae are of importance to us when analyzing the concepts of feudalism and capitalism, because they are films that contain in them examples from these two types of economic systems. While the concept of unions is prevalent in both films, the reasons for their existence and the results of their existence appear to be quite different, but important all the same. Thus, the films can also be used to help increase our understanding of the importance and the role of unions in society. John Sayles, the writer and director of Matewan, produces for the audience a true depiction of the West Virginian coal-mining community of 1920. At a surface-level viewing and examination of the film, many might be tempted to view the environment that is created as capitalist. After all, the workers do get paid for their services. However, upon a much deeper, more in-depth inspection one could argue that there is much evidence toShow MoreRelatedThe Fall Of Feudalism And The Rise Of Capitalism1304 Words à |à 6 PagesThe fall of feudalism in the 12th century eventually led to the rise of capitalism. To get there, the first thing needed was a change in thinking. This began with the scientific revolution, and led to the Enlightenment in the 18th century. The Enlightenment, also known as the Age of Reason, was highlighted by individualism, reason, and skepticism. Skepticism caused people to denounce divine right of kings, thus moving from monarchies to democracies. This desire fo r knowledge coupled with the scientificRead MoreKey Differences Between Feudalism And Capitalism996 Words à |à 4 Pagesdifferences between feudalism and capitalism. Explain how Heilbroner discusses the rise and establishment of capitalism? In this short essay, I will explain few key differences between feudalism and capitalism based on Heilbroners book. They are as follows: the property rights (Land), the system of wage and labor (Workers), and the existence of competition. Additionally, I will discuss the rise of capitalism based on Heilbroner point of view. Both feudalism and capitalism are defined by manyRead MoreTo What Extent Is American Capitalism Representative Of European Medieval Feudalism?2015 Words à |à 9 PagesExtent is American Capitalism Representative of European Medieval Feudalism? American capitalism is the foundation by which economic growth has propelled the U.S. economy to be a powerhouse. A system based on free enterprise and the ââ¬Å" sweat of our browsâ⬠, it establishes the notion that it is a progressive step in equality and is detached from past economic systems. If one were to look closer, however, it becomes apparent that capitalism is not much of a far cry from feudalism in medieval europeRead MoreFeudalism and How It Affected Old England792 Words à |à 3 Pages Feudalism was a very important aspect in developing the political organization in medieval England. It was one of dominant governments used by the nobles. Feudalism was when one of the kingââ¬â¢s noblemen would give land to a man known as a fief and give the fief people to work the land for him. These people are known as serfs. The fief would then protect the serfs from being attacked as long, as long as the serfs worked the land to provide an income for the fief. If the fief accepted the noblesRead MoreCapitalism And Capitalism883 Words à |à 4 Pagesthe stones that when put together, help to form Capitalism. Capitalism in essence, is a system of economic value in which private ownership is the source of production (Such as factories, and farming). Goods are produced and in return, income and profit are gained. The generally accepted characteristics of what Capitalism is, such as private property rights, specialization of jobs, profits, division of labour, did not originate around Capitalism. In actuality, these were just the stepping stonesRead MoreThe Communist Manifesto By Marx943 Words à |à 4 Pagespeopleââ¬â¢s ancestors were lazy and capitalism starts with violence of one class against another. Marx mentioned, ââ¬Å"The history of all existing societies is the history of hitherto class strugglesâ⬠, struggles between oppressors and oppressed. In history, Ancient slavery and society evaluated over time to feudalism than to capitalism where minority and majority groups existed. The minority group in ancient slavery and society was the kings and the majority was the slaves. Feudalism, the minority was the lordsRead MoreKarl Marx And The Productive Power1182 Words à |à 5 Pagessocial rebellion. In the following chapters I will explain how the mode of production for feudalists, capitalism, and socialism will possibly lead to communism. I will elaborate on the social conflict, exploitation faced by the oppressed, and why Marx believed that the mode of production from these classes, except communism will inevitably self-destruct. Feudalism The very definition of the term feudalism as it relates to the 19th century is that of a dominant social system in medieval Europe, in whichRead MoreMain Reasons for the Fall of Feudalism1067 Words à |à 5 PagesFeudalism developed as a result of the frequent invasions made by the vikings during the Middle Ages around the 900s to early 1500s. Feudalism served its purpose by creating a system where the king would appoint lords that would appoint knights to appoint serfs that would be expected to work the land and fields in exchange for food, protection, and accommodations. It provided stability because lords were able to govern smaller groups of people through a system called manorialism. Feudalism allowedRead MoreWays in Which the French Revolution had a Lasting Impact on France853 Words à |à 4 PagesFrench Revolution. This in itself shows that the revolution had a major impact on France. It played a significant role in changing France through, for example, the new definition of nationalism, the abolition of the monarchy and the abolition of feudalism. Whether these changes succeeded in modernising France or resulted in something that was not any better than pre-revolutionary times is what will be discussed in more detail using the above three examples. Nationalism did exist, to a certain extentRead More The Formation of Capitalism in European History Essay1354 Words à |à 6 PagesThe Formation of Capitalism in European History Pure capitalism is characterized by private ownership of resources and by reliance on markets, in which buyers and sellers come together and determine what quantities of goods and resources are sold and at what price. Here no central authority oversees production and consumption. Rather, economic decisions are coordinated by the actions of large numbers of consumers and producers, each operating in his or her own self-interest. Because property
Opportunities Their Respective Potentials â⬠Myassignmenthelp.Com
Question: Discuss About The Opportunities Their Respective Potentials? Answer: Introducation The case organization Nokia, is Finnish multinational in information technology and communication business. The company has several divisions/avenues through which it operates and transacts business. Among these divisions is the handset division which has a reputation across the world for its durable and reliable handsets with wide market acceptance across the world. (Pai, 2015). Project topic In the year 2014 Nokia Corporation sold its handset making division to Microsoft Corporation and decided to focus on its other areas of its telecommunication business. However three years later in 2017 Nokia is making a comeback into mobile phones market by introduction of a trio three of Nokia branded phones running on Android operating s namely Nokia 6, 5 and 3. One of the biggest opportunities Nokia Corporation can leverage on as it attempts to gain a market share in Smartphone business is their brand name. Many consumers still recognize Nokia phones because of their reliability and durability. Perception is everything in sales once a product has a good perception in the market even if it disappear for a while consumes will likely receive it back well if its re-introduced. The phones also tend to have much higher resale value compared to other brands which exist in the market. They are also easy to use and the lower segment of the Smartphone market will likely prefer Nokia brands over competition. The price range is also wide which in turn translates to wider market for the Nokia brand of handsets. (Leelakulthanit and Hongcharu, 2012) Purpose of the research Therefore, the purpose of this research is to carry out an investigation into opportunities available to Nokia for its handset division even as it embarks on reintroducing the devices back into the market. The research will analyze and highlight these opportunities to Nokia Corporation and make recommendation on how best it can tab on them in order to successfully re-launch its handset product back into the marketing. (Allen, Graupera and Lundrigan, 2010) The following concepts/theories relate to this topic. PESTLE analysis SWOT analysis The research will take the form of single case study in the name of Nokia corporation handset division as a unit of analysis. The secondary data will be collected from a number of previously done researches on the same topic as well as other forms of publications that fall within the area of study of this particular research. In particular the research will leverage on the following industry reports Global Market Analysis and Outlook: Disruption In Change Market (Anon, 2017) and Smartphones Market Trends (Strategyr.com, 2017) among other industry related reports. The research will also draw secondary data from Nokias annual reports (Nokia, 2011; Nokia 2012; Nokia 2014). The information will be used to indentify opportunities available in Smartphone sectors and draw comparisons to Nokias opportunities. The research will utilize both qualitative and quantitative data analysis to identify Smartphone market opportunities available in the market and quantify these opportunities to see the ir respective potentials.

Notes Chris Cunningham Case Essay Example
Notes: Chris Cunningham Case Essay He has good qualities. This could be done by refusing him new clients, giving him a performance review, making public high level disapproval of his tactics. Tie production to consumption. Make it clear to Chris that his income will be affected if he continues. Following this point, Opponent urged consideration of why Chris finds it so easy to influence production. He has close personal ties to Mrs.. Stoves. Staff are probably gossiping about favoritism, adding to resentment. 2. Mention a possible career path to sales director, and the need to change his behavior if he wants such promotion. Some students perceived this as apparently rewarding undesirable behavior. Opponent pointed out that, as Chris works on commission, his behavior is already rewarding him. 3. In tackling this herself Mrs.. Stoves is undermining the sales director. Theres a problem with the organizational structure. 360 degree feedback should be employed to get other peoples perceptions of Chrisms behavior. We want Chris to honor lines of authority. 4. Focus on head of production. Give him more prestige, perhaps Chris should report to him. 5. Problem with production maybe not enough, so build up inventory, and reduction capacity, outsource. 6. Problem with sales director, only a figure head. Give him the power to solve problem. 7. Fire Chris. Opponent made the point that all of these actions would destroy Chrisms productivity! However, Chrisms sales are not the same thing as the company profitability, even if he thinks they are the same. What is his behavior costing the company? Not only in money, but in human relationships. Citing a toy company he had advised in LA, Opponent said that this question may not be one that the accounting department could answer.

However, all his experience is in sales, due to the divided structure of the company. Another set of actions was proposed by the students: 1 . Bring in just-in-time so that production will be flexible enough to meet Chrisms needs. Change organization to support Chris-type salespeople. 2. Rank customers by profit they bring and prioritize production accordingly. Therefore, 2 main options: Restrain Chris, and change organization to do dhal r use him as he is and change organization to support him.

Calcium Carbonate and Ca2+ Ions Essays
Calcium Carbonate and Ca2+ Ions Essays Calcium Carbonate and Ca2+ Ions Paper Calcium Carbonate and Ca2+ Ions Paper Experiment. EDTA Titration of Ca2+ in an unknown solution Experiment. EDTA Titration of Ca2+ in an unknown water sample Modified 9/2012 Objective: The most common multivalent metal ions in natural waters are Ca2+ and Mg2+. In this experiment, you will find the total concentration of calcium ions that can react with EDTA with the assumptions that EDTA reacts 1:1 with metal (Ca2+) ions. Equipment 250-mL Erlenmeyer flask (3) 50-mL Buret Ring-stand and hardware Desiccator 400-mL Beaker 500-mL Vol. flask 250-mL Vol. flask 1. 0-mL Vol Pipette 100-mL Grad cylinder Hot plate Safety and Waste Disposal Chemicals Buffer (pH 10): Add 142 mL of 28 wt % aqueous NH3 to 17. 5 g of NH4Cl and dilute to 250 mL with water. Eriochrome black T indicator: Dissolve 0. 2 g of the solid indicator in 15 mL of triethanolamine plus 5 mL of absolute ethanol. 50 wt % NaOH: Dissolve 100 g of NaOH in 100 g of H2O in a 250-mL plastic bottle. Store tightly capped. When you remove solution with a pipet, try not to disturb the solid Na2CO3 precipitate. Discussion: Hard water is due to metal ions (minerals) that are dissolved in the ground water. These minerals include Ca2+, Mg2+, Fe3+, SO42-, and HCO3-. Generally hard water arises because rainwater moves through limestone, CaCO3 underground that occurs in our area to the aquifer. This is why we measure hardness in terms of CaCO3. The concentration of the Ca2+ ions is greater than the concentration of any other metal ion in our water. The determination of water hardness is routinely used to measure the quality of water that the general public uses. Originally, water hardness was defined as the measure of the capacity of the water to precipitate soap. Hard water is not a health hazard since the main chemical in hard water is calcium. People regularly take calcium supplements. In fact, hard water can be a source of necessary minerals (calcium and magnesium) that is necessary for good health. Indeed, the National Academy of Science go so far as stating that that consuming extremely hard water could be a major contributor of calcium and magnesium to the diet. The problem with hard water is that it cause soap scum, clog pipes and clog boilers. Soap scum is formed when the calcium ion binds with the soap. This causes an insoluble compound that precipitates to form the scum you see. Soap actually softens hard water by removing the Ca2+ ions from the water. When hard water is heated, CaCO3 precipitates out, which then clogs pipes and industrial boilers. This leads to malfunction or damage and is expensive to remove. There are two types of water hardness, temporary and permanent. Temporary hardness is due to the bicarbonate ion, HCO3-, being present in the water. This type of hardness can be removed by boiling the water to expel the CO2, as indicated by the following equation: HCO3- (aq) ? H2O (l) + CO2 (g). Because bicarbonate can be removed it is classified as temporary hardness. Permanent hardness is due to the presence of the ions Ca2+, Mg+2, Fe3+ and SO4-2. Because boiling cannot eliminate this type of hardness, the water is said to be permanently hard. The table below shows the degree of hardness of the water in terms of its calcium carbonate concentration in ppm and grains. Hardness rating Soft Medium Hard Hard Very Hard Concentration of Calcium Carbonate (mg/L or ppm) 0 75 75 to 150 150 to 300 300 and greater Concentration of Calcium Carbonate (grains/US gallon) 0 to 5. 2 5. 2 to 10. 5 10. 5 to 21 21 and greater Permanent hardness is usually determined by titrating it with a standard solution of ethylenediamminetetraacetic acid, EDTA. The EDTA is a complexing, or chelating agent used to capture the metal ions. This causes water to soften, but the metal ions however, are not removed from the water. EDTA simply binds the metal ions so that the ions do not precipitate to form soap scum. EDTA is a versatile chelating agent. A chelating agent is a substance whose molecules can form several bonds to a single metal ion. Chelating agents are multidentate ligands. A ligand is a substance that binds with a metal ion to form a complex ion. Multi-dentate ligands are many clawed, holding onto the metal ion to form a very stable complex. EDTA can form four or six bonds with a metal ion. It is frequently used in soaps and detergents because it forms complexes with calcium and magnesium ions. The ions in hard water are bound to the EDTA and cannot interfere with the cleaning action of the soap or detergent. EDTA is also used in foods. Certain enzymes are responsible for food spoilage. EDTA is used to remove metal ions from these enzymes. It is used to promote color retention in dried bananas, beans, chick peas, canned clams, pecan pie filling, frozen potatoes and canned shrimp. It is used to improve flavor retention in canned carbonated beverages, beer, salad dressings, mayonnaise, margarine, and sauces. It inhibits rancidity in salad dressings, mayonnaise, sauces and salad spreads. In this lab you will be asked to determine the total permanent hardness. EDTA grabs all the metal ions in the water, not just the Ca2+ ions. This gives us a value that is not truly the concentration of Ca2+ ions. This causes an experimental error of about 1%, which is acceptable due to the fuzzy endpoints in this type of titration. Erio-T indicator or Eriochrome Black-T indicator is used in this titration. When it is chelated or acidifies, it produces a Pink-Red solution. When it is not chelated and under basic conditions it is Blue. The three pictures show the end point in this titration. There is a 1-drop difference of 0. 01 M EDTA between the first and second pictures and between the second and third pictures. Two or three seconds were allowed for colors in the second and third pictures to develop after adding the additional drop. In each case the solution was thoroughly mixed. This color change from wine red to violet to blue is due to the compact nature of the complex. Experiment. EDTA Titration of Ca2+ in an unknown solution PROCEDURE Modified 9/2012 1. Dry Na2H2EDTA. 2H2O (FM 372. 24) at 80à ° C for 1 h and cool in the desiccator. Accurately weigh out ~ 0. 6 g and dissolve it with heating in 400 mL of water in a beaker. Cool to room temperature pour into a 500-mL volumetric flask. , mix and dilute to the mark. 2. You should practice finding the end point several times by adding a little tap water in a clean beaker and titrating with EDTA. Save a solution at the end point to use as a color comparison for other titrations. 3. Pipet a 1-mL sample of unknown into a 250-mL flask and fill to the mark with deionized water. Mix thoroughly. From this 250-mL stock solution draw 4, 50mL aliquot samples and place each aliquot in 250mL Erlenmeyer flasks. To each sample, add 3 mL of pH 10 buffer and 6 drops of Eriochrome black T indicator. To the first 50-ml solution, titrate with EDTA from a 50-mL buret and note when the color changes from wine red to blue. 4. Repeat the titration with the next three samples to find an accurate value of the total Ca2+ concentration. Perform a blank titration with 50 mL of distilled water and subtract the value of the blank from each result. 5. Upon completion of the experiment, discard all solution in a chemical waste bottle and wash out the glassware. Be sure to dry your buret in the upside down position. _________________________________________________________ Calculations ââ¬â Analysis: Analyte Ca2+ The reaction of Ca2+ ions with H2EDTA2- takes place with a 1:1 stoichiometric ratio: Ca2+ + EDTA2- ?
