The Crucible by Arthur Miller Essay Example for Free

The Crucible by Arthur Miller Essay he Crucible emerged from a true story which makes the play more convincing. It was based on the Salem, Massachusetts Witch Trial in 1629. At the time people were extremely religious and believed in witchcraft and devilry. It was strictly forbidden for people to dance, sing, and laugh and if they were discovered doing these activities, they were accused of witchcraft and many were to die of this. Miller decided to write a play which would heighten Americas awareness of the impending of the communist in the 1950s. It is important for the audience to understand the historical background, and understand what living in Salem, Massachusetts was like in the 17th Century. The people of Salem were Puritans- descendents of the Pilgrim Father, who arrived in America from England in 1960 because they wanted a stricter way of life with regard to their religion. Their lives consisted of working, eating, sleeping and praying. Any kind of enjoyment was prohibited. This meant that singing and dancing was forbidden and seen as an interaction with the devil. People of Salem believed in witchcraft, and in 1692, many people were accused and hanged because of this. People incriminated each other, both neighbours and friends. This shows that although on the surface, society appears united, cracks were beginning to emerge. In the 1950s there was a modern day witch hunt in America. Instead of hunting witches Free thinkers, That is people who had individual thoughts were accused of disloyalty and communist sympathies, which often resulted in loss of their jobs. In order to protect themselves, just as in The Crucible, they blamed others. The Crucible was inspired by Millers experiences of the 1950s. It was Senator Joseph McCarthy who created the hunt for communists. The similarities between the Crucible and McCarthys accusations of the 1950s were denounced. Without proof or evidence the inciting of fear and suspicion would lead in the 1950s to the eventual break up of families and friendship as people accused each other of disloyal acts against America. This was to lead to America becoming permeated by paranoia and scepticism. Before the audience even meets Abigail, they find out that she is a trouble maker with an endless capacity for dissembling. In the opening act between Parris and Abigail, tension rises as Parris persistently questions her about the night they were dancing in the woods, what did you do with her in the forest? But Abigail denies any accusations and always defends herself, But we never conjured spirits. However Parris does not stop questioning her and feelings begin to heighten when he mentions witchcraft, trafficked with spirits in the forest. Abigail vehemently assents herself by saying, we never conjured spirits. At this stage she is trying to defuse the situation but the audience are already experiencing a steady rise in tension.

An Analysis of Singing to Wolves Essay -- Singing to Wolves

   An Analysis of â€Å"Singing to Wolves†Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚      The poem,   â€Å"Singing to Wolves† is a modern poem,   that tries to explain to the reader how wonderful solitude is,   but also considers it’s negative side,   with the example of a lonely girl.   The poem starts off with a brief encounter into the history of Wales,   and talks about the Llanthony monks,   who the reader is told were unloved by the Welsh,   and thus driven to a lonely life in the wilderness.   By reading this poem,   it seems as though being unloved is a popular reason for solitude.   After this brief insight into Wales’ history the reader is then taken back to the realms of modern day living.    â€Å"Why should we stay here singing to wolves?†    This opening sentence seems to act as a kind of question,   which is answered in the course of the poem.   At first it sounds like a stupid thing to do,   but eventually the reader realises that the wolves become very symbolic in the poem.   Wolves are thought of as being ruthless hunters of the wilderness,   and one could hardly imagine them being impressed by the singing of any person. For the monks the Wolves were those that despised them (the Welsh),   and by â€Å"singing† to them,   they were actually trying to convince them of their belief etc.   And seeing as no-one ever listened to them,   they may as well sing to the wolves,   as they take just as much notice of them.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   However the wolves also have another interesting metaphorical meaning in the poem.   These days they no longer roam Britain,   and have all died out,&nb... ...flowers†¦Ã¢â‚¬     Another interesting thing that the poet makes use of is semicolons.   These are used throughout the three stanza’s.   The point of these semicolons is to make the sentences seem longer,   and bring a certain amount of continuity to it.    â€Å"†¦said Llanthony monks;   and left for soft living†¦Ã¢â‚¬     Once one has recognised the ideas behind the text,   one realises that the poem tries to make the reader think about the world he lives in,   and maybe even prompt him into looking more deeply into his way of life,   and try not to simply follow the pattern that everybody else makes.   The poet has don this by using the example of the monks in the past years,   and the little girl in our modern world.   Maybe he wants the reader to find a medium between becoming a statistic,   and singing to wolves.

I would then type up the report whilst it was fresh in my mind. If the child was not safe or at risk of harm and had to be removed from the home I would wait until the appropriate people attended. Depending on the severity of the abuse, I may call the police, child protection and health professionals. We have a duty of care by law to report any safeguarding issues/concerns with the appropriate people. We should NOT confront an alleged abuser.

Priority Sector Lending - 28386 Words

The Draft Technical Paper on Review of Priority Sector Lending, prepared by the Internal Working Group set up in Reserve Bank under the chairmanship of Shri C. S. Murthy, Chief General Manager-in-Charge, Rural Planning and Credit Department, was placed on the RBI website on September 30, 2005 for public opinion.

There is another view that enlargement of areas has resulted in loss of focus. It is also held that credit growth in housing, venture capital and infrastructure has been strong while it has been sluggish in agriculture and small industries. Further, it is argued that only sectors that impact large population, weaker sections and are employment-intensive such as agriculture, tiny and small industry should be eligible for priority sector. Since there are several issues that need to be considered in this regard, it is appropriate that these are debated and examined in depth†. 1.4 In order to examine the issues raised in the Annual Policy, it was decided that an Internal Working Group be set-up for the purpose. a) to examine the need for continuance of priority sector lending prescriptions; b) to review the existing policy on priority sector lending including the segments constituting the priority sector, targets and sub-targets, etc.; c) to examine the suggestions received regardingShow MoreRelatedPriority Sector Lending2487 Words   |  10 PagesPRIORITY SECTOR LENDING Some areas or fields in a country depending on its economic condition or government interest are prioritized and are called priority sectors i.e. industry, agriculture.

The Tension Between National Security And Individual Privacy

The Situation The tension between national security and individual privacy has long existed even before the development of digitized information. Recently, two main forces have advanced the debate over this balance to the forefront of the public eye: 1) the proliferation of data by private sector companies and 2) the heightened need for homeland security and public defense. With the rapid evolution of technology, companies have aggregated pools of consumer data to improve upon internal decision making. In some cases, however, this data can be leveraged to ensure national security and public safety. This juxtaposition of enterprise and security results in a blurring of the line dividing public and private sector responsibilities. The question becomes an issue of moral obligation versus legal responsibility. What are we as consumers and citizens willing to sacrifice in exchange for safety? And does the private sector inevitably succumb to obligations originating from the public sector? The company on the forefront of this issue is Apple. After the tragic events in San Bernardino, CA on December 2, 2015, the United States FBI located an iPhone 5C belonging to one of the terrorists. The FBI, however, was unable to access the phone and formally requested Apple to unlock the device to facilitate the search for information about the killers.

The Dark Side Of Globalization - 1191 Words

Normandin Week One: The Dark Side of Globalization While globalization can be defined and described a multitude of ways, the concept of globalization encompasses a system in which global interdependence and awareness has increased (Robertson, 1992: 8) at an exponential rate. Our connections to each other and to events that happen in diverse locales is rapidly intensifying (Giddens, 1990: 64). The pace at which these changes have occurred have been alarming and have been difficult to adjust to (Lerche, 1998), leading to several serious â€Å"conflicts of globalization† we now face. Environmental Degradation: Globalization’s Double-Edged Sword Globalization has brought about the increase in production of goods, the rapid transport of goods, and†¦show more content†¦Economic power as a driving force is propelling the world into one economy and shoehorning sovereign nations into a haphazard loose political collective. Of course, the states with the strongest economies and cultivated power fare the best with smaller states aligning with more powerful states, retreating inwardly, or hobbling along at varying degrees of success and failure within the world economic system (Ake, 1995: 26). The system encourages the continuation of Western hegemony and fuels the power of global corporations. Wealthier countries experience significant risk to their citizenry due to loss of jobs as corporations opt for exploiting the labor force in poor countries to obtain cheap labor (Lerche, 1998). Because profit is the prime directive in business and necessary for survival for multi-national business entities, it makes sense that industries and incomes would be affected. Individuals from poorer nations are exploited, citizens from more developed states are deprived of income, usually from manufacturing positions, and the power base of these multi-national business entities is increased, often empowering them to a level similar to or greater than states.

Diffusion and Osmosis Lab free essay sample

To simulate and observe the diffusion of solutes and the osmosis of water through a semipermeable membrane through color change and sugar tests. 2. To speculate osmosis occurring In dialysis bags and potato cores by comparing percentage change in masses. Background information: Molecules are always in random, constant movement due to their kinetic energy. This causes the molecules of a cell to move around and bump into each other. The random movement of molecules from an area of high concentration to low is called iffusion. Osmosis, a specific kind of diffusion with respect to water takes place in the cells. This kind of diffusion is where water moves through a selectively permeable membrane, that Is, a membrane that only allows specific molecules to pass through. Diffusion and osmosis stops when a dynamic equilibrium Is reached, that Is, the concentration on both sides are equal to each other. To be noted, that at this point, molecules are still In constant motion and random movement; however, the rates at which molecules moving from one area to another are equal and there is no net ovement occurring between the two areas. We will write a custom essay sample on Diffusion and Osmosis Lab or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page If two solutions have reached this equilibrium state, they are said to be isotonic. If they differ, the solution with a higher concentration of solutes is hypertonic with respect to the other; the solution with lower concentration is hypotonic. Water potential describes the tendency of water moving to another area. Since solutions always tend to reach a state of equilibrium, water usually moves from a hypotonic solution to a hypertonic solution in order to dilute the higher concentration. Therefore, we say that hypotonic solutions have a ower solute concentration and a higher water potential. The net movement of water In a plant cell can be described using the two terms, turgor pressure and plasmolysis. Turgor pressure refers to the pressure of water exerting against Its plasma membrane, which helps maintain the shape of the cell. When a plant cell is placed in a hypotonic environment, water moves into the cell, causing higher turgor pressure. However, when placed in a hypertonic solution, water moves out of the plant cell, therefore causing the cell to lose its turgor pressure. The loss of water and urgor pressure while a cell is in a hypertonic solution is called plasmolysis. In conducting this lab, we will be simulating diffusion and osmosis that occurs in the cells by using dialysis bags potato cores. In comparing the percentage changes in mass of these test objects after an isotonic state has been reached, we will be able to speculate If water has moved into or out of the bag. Materials: Part A: dlalysls tubing, Iodine Potassium Iodide (IKI) solution, 15% glucose/ 1% starch solution, glucose Testape or Lugols solution, distilled water, and a 250mL beaker. nd a 1. M sucrose solution; six 250-mL beakers or cups, and a scale. Part C: a potato, knife, potato core borers, distilled water; 0. 2M, 0. 4M, 0. 6M, 0. 8M, and a 1. 0M sucrose solution, and a scale. Procedure: Safety Precautions: Keep the potato core pointing away from you and other students when cutting the potato cores out Be careful cutting the potato slices, ask an adult or get a responsible person. Reference: Refer to Lab One Diffusion and Osmosis Handout Observations: Data: Analysis: Part A: Lab IA Questions: 1. Glucose is leaving the bag, we know this because initially there was no change in colour of the Testape in the beaker, but our final data shows, there was glucose present in the beaker. The Iodine-potassium-lodide is entering the bag because initially we tested the beaker for starch using the Iodine-potassium-lodide solution and at that time, the solution color in the bag was clear, by the end of the experiment, it was a dark blue color, which is a positive test for starch. Water is also entering the bag, because although the initial and final mass of the bag before and fter the soaking was not recorded, we noticed an increase in size of the dialysis bag. 2. The results show the IKI moved from the beaker to the bag, causing the change of color of the solution in the bag. This was because there was a higher concentration of IKI molecules in the beaker than in the bag, so the IKI molecules moved from an area of high concentration to an area of lower concentration in a process called diffusion
