Human Resources, Training and Development, Appraisals Essay

Human Resources, Training and Development, Appraisals - Essay Example The troubles that normally arise under formal evaluation procedure are: malfunction to finish the evaluation on time, lack of stability and objectivity evaluating the human resources, and a discernment that the entire procedure is hectic work of little value. (Lukesh, 2000) Except top hierarchy dynamically participates and takes principal task for the evaluation procedure, the rest of the human resources in the company is unconfident of the worth and significance of performance evaluation. A performance evaluation should produce quantifiable results that are visible to all workers in terms of enhanced performance through training, a compensation system that is just and is so professed and a promotion and transfer system that makes the correct decisions associated to abilities. The human resources department in cases does not have the status to provide performance evaluation an elevated priority. Nevertheless they can guarantee that the performance evaluation has a possibility for triumph by scheming a strong evaluation tool, efficiently training supervisors to evaluate accurately, developing purposeful criteria for measurement and viewing how performance delivers to the bottom line. (Pardue, 1999) I would use method based on key performance indicators (KPIs) for appraising sales people.

US Intel Community Essay Example | Topics and Well Written Essays - 1000 words

US Intel Community - Essay Example The great thing about this agreement is that there is a common face to it and is apparently diplomatic and open addressing on alien nations1. But there is as well a dark and covert side and although they allegedly are not appropriated to operate domestically, they do act domestically through the big private institutions - enforcing the policies of the UN Organizations. Understanding that explains how UN policies are interconnected and enforced in the United States. From the start of this nation history, there have been two sects - Internationalists and Nationalists. The Nationalists were our Founders. The Internationalists were the Tories - oppositions of independence. Traditionally, the military have been accountable for interior security and homeland defense. The National Security Act of 1947 regrouped the leadership of the armed forces following Second World War, validating a Defense Department (DOD) with a Secretary of Defense (SECDEF) that content directly to the Commander-in-Chief. As we now acknowledge, the NSC was not arranging a great job aligning all the facets of Office of Homeland Security2. For instance, border security was addressed in a split way by a number of agencies. Intelligence was not being effectively shared. To start with, from ethical point of view, the National Security Act of 1947is an act that governs all partaking office with origins and roots from the US governance. Taking the account that United nation is excluded from the provision of United states intelligence information is unethical on account that the organization has rights as far as the laws is of concern. The organization has been of help in identification of individuals disputes and always alerted the States on any prevailing measures needs to be taken just on time. 2. How would you define "morally intolerable" and "morally acceptable" from an intelligence operation perspective concerning national security? Is torture of terrorists or enemy

Ayatollah Khomeini and Gamal Abdul-Nasser Essay

Ayatollah Khomeini and Gamal Abdul-Nasser - Essay Example However, this assertion is contested. This is because at the time of the revolution, Iran was experiencing un-employment rate of approximately 30%1. Unemployment is one of the indicators of poor development and economic growth. Based on this fact, the assertion that Iran was politically and economically stable is false, and does not hold any ground. On the other hand, the revolution in Egypt occurred when the country was experiencing a series of poor political and economic governance. Despite the differences in these revolutions, and the two leaders, Gamal Abdul Nasser and Ayatollah Khomeini shared a lot of similarities as well as differences in their leadership structure and system2. One major similarity is that the two leaders were charismatic, and they sought to eliminate any form of opposition to their leadership. For instance, Nasser ordered a crackdown on the Muslim Brotherhood, a group that was opposing his leadership, while Ayatollah Khomeini sought to kill any political supporters of the Shah. This paper takes a stand that both Ayatollah Khomeini and Gamal Abdul-Nasser were charismatic leaders, who influenced their societies and people, despite their undemocratic systems of governance. Gamal Abdul Nasser was the second Egyptian president, and he began his presidency in the year 1956, to the time he died, which was in 1970. He played an instrumental role in the overthrow of the Egyptian monarch in the year 1952, and as a result, he was rewarded with a post, as a deputy prime minister3. This is an indication that Gamal Abdul Nasser was an important leader to the revolutionaries, and he was held in high esteem. Furthermore, the power and authority that Gamal Abdul Nasser had is depicted when he managed to arrest President Muhammad Naguib, and place him under house arrest.

The novel Frankenstein Essay Example for Free

The novel Frankenstein Essay Evil in many individuals is seen as having qualities tending to injury and mischief or as having a nature or properties which tend to negative behavior. The theme of evil is very important to the novel Frankenstein. It is important because, everyone, at one point or time, is seen as evil. Just because they are perceived as evil, it doesnt necessarily mean that they are evil. Everyone can possess the qualities of being evil but that doesnt mean that they should be perceived as evil. In relation to the novel, everyone sees things from their own point of view which therefore creates a whole misunderstanding of the word evil. At the beginning of the novel, a monster is brought into the world by his creator, Frankenstein. Frankensteins dream was to create this monster but it turns out to be what he least expects it to be. Frankenstein perceives the monster as a thing of evil from the moment he brings it to life. Frankenstein than in turn hates the monster. He spent 2 years of his life working on infusing life, into an inanimate body, to than in turn hate it because he perceives it as evil. Frankenstein than abandons the monster because he is disappointed with what he created. The reason he perceives the monster as evil is based mainly on the physical appearance. The monsters muscles and arteries were still showing, and he displayed physical characteristics that would be seen as irregular to society. He believed these irregularities were seen as evil, which in the end, resulted in the desertion of the monster. Since the monster had been abandoned, it ends up wandering into a forest and runs across a town. The villagers visualize it and in turn, throw stones and many other missile weapons at it. This forces it to take refuge back into the forest. This is the first clue that the monster realizes. It eventually sees the problem that he possesses. It sees that it its physical appearance is rather grotesque and apprehends the fact that this may be why he was seen as an outcast to the villagers. On his continued adventure into the woods he comes across a cottage which is occupied by people. It sees this as a chance to be socially accepted into the world. With the physical characteristics, that the monster possesses, he comes to the conclusion that he must understand the human nature to a certain extent, to ensure that he will be accepted into society. It spends the majority of a year outside of the cottage studying up on the human behavior of these cottagers. It recognizes that they possess the ability to communicate through sounds. It attempts to learn the language that they speak, so he could communicate with them verbally. It wants to communicate with them verbally to ensure that they might see it as more human-like than previously discovered. It also attempts to help the family out by surprising them with jobs that were mysteriously accomplished. All this knowledge and help still does not help out the chances of fitting in with the family.

Environment Primary Factor That Influences Plant Growth Development Biology Essay

Environment Primary Factor That Influences Plant Growth Development Biology Essay Although there is no doubt that the world population grows up in more gradual way every year, demanding more food than any other time before, Environment is the primary factor that influences the plant growth and development and has also the greatest effect on the crop distribution on the earth. In this ten page report, the most important environmental factors that affect the crop growth and development namely light, water, temperature and carbon dioxide are covered, emphasizing their influences on crop productivity. Moreover light as the most environmental factor importance on crop production and productivity, all light quality, quantity and duration effect directly on crop yields, also in most cases plant reactions and processes are greatly influences by the temperature, plants key process affected by temperature is photosynthesis followed by germination, transpiration, respiration and flowering. However, crop temperature requirements in a specific physical, chemical or biochemical process varies from one spice to another resulting difference among crops in their geographical distribution. On the other hand, water and humidity play an important role for the crop productivity since most plants need 90% water content to grow effective and efficiency way until some crops like rice demand flooding the area to grow properly. In addition to the plant water needs, plants are number one consumers of carbon dioxide on the earth so as to synthesize food and energy. Each of these factors were discussed in this report emphasizing and giving more detailed look on their effect on crop productivity. Light Why solar energy is important to a successful plant growth, development and improvements to its yields? On the planet life is mostly solar-powered, sun is the only natural source of light energy, all the living organisms depend on the amount of light energy (solar radiation produced by the sun) harvested by green plants at any level of ecosystem, only few types of bacteria can derive the energy they require from sulfur and other inorganic chemical compounds or substances. Photosynthesis which is the process that the plants manufacture their food molecules from carbon dioxide and water by using the sun light, therefore the rate of duration of photosynthetic activities directly effects the amount of dry matter produced by the plant, and energy harvested as crop yields to transfer energy from primary producers to the other components of the ecosystem which are the consumers, so the ultimate source of food in the globe is the green plant, because plants have the ability to harvest and ut ilize the sun light manufacturing a usable food after three main consecutive processes during plants photosynthetic activities. Photosynthesis The management of that resources available to the production, that the crop requires to grow and develop and show its potential genetic characteristics as much as possible is a major factor that contribute the dramatic rise of the crop production, only organisms/plants that contain a certain pigment called chlorophyll which is the most abundant enzyme/protein on the earth are capable to utilize solar energy directly. It is therefore; light is an important factor to produce energy by the plants and the energy produced will be supplied to the different levels of the ecosystem. The light influence on the plant development and productivity can be discussed into three main categories. Quality of light The intensity of light and its concentration are what decide the quality of light; light densities differ from one season to another, countries that have three or four seasons, the largest amount of light is found in the summer season, where the least amounts are available in the winter, as the case is in many European countries, but areas like Malaysia the amount of light available throughout the year is almost the same, so the light intensity varieties depend on the geographical area, for example in Sub-Saharan Africa where the climate is desert, clouds and other sun light barriers are not found in the atmosphere, the sunlight density is very high. Not straying from the main point, the more light radiation that a plant harvests, the greater and the ore ability to manufacture food through photosynthetic processes even though this relationship will depend on the pathway group that a certain plan flows. From this interactions, the scientists specially those botanists, ecologists and physiologists realized the direct relationship the amount of light available to the plant and the crop productivity, that is why the greenhouse managers to fix artificial light sources to supply light their fields to create longer photoperiod in the greenhouse targeting more improvements to the final output, even though this strategy will negatively affect the cost of every unit produced under this system. However, they can easily manipulate the amount of light of the planned growth patterns to their plants. Quality of light Are there different light qualities? Light colors, which can be divided into bands of red, yellow, blue, orange, violet and indigo. The red and blue color lights that the plant can absorb have the biggest influence on crop growth, the blue light is primarily responsible to the leaf vegetative growth and the combination of red and blue lights encourage the flowering process. The solar rays produced by the sun, or what is normally known as wavelength of the light constitute the light quality, wavelengths that the sun sends to the earth ranges 250 7000 nanometers, these solar rays reaching the earth are divided into eight parts, only the visible radiation is called light, and the other which are Cosmic rays, Gamma rays, X-rays, Ultraviolet, Infrared, Microwaves and Radio waves are invisible. The visible solar rays or light is the small proportion of the range of wavelengths of the electromagnetic radiation occurring somewhere between 400 and 735 nanometers. In other words the visible light is between Ultraviolet which are shorter waves than 390 nanometers and Infrared which are longer waves than 700 nanometers. Only 47% of the light produces by the sun is gained by the earth (P. Bannister 1978), where the other 53% part of it is absorbed by the atmosphere while other part is reflected by some barriers and finally gained by the space. Only 2% of that 47% o f the light that reaches the ground is used in the photosynthetic processes and about 10% is used different processes that occur in the plant. Duration of light Photoperiod or the duration of light is referred to how long of time the plant exposes to light, the flowering of many plant species is controlled by the photo duration, as a result that, the plant physiology experts tend to name and classify plants into short-day and long-day plants relating to under which condition do these crops flower. In contrast, the duration of uninterrupted darkness which presents a critical situation to the crop development and flowering process is the factor that show the importance of light duration not only the plants but also on farm animals specially poultry production therefore shorter darkness periods are encouraged. The amount of carbon dioxide fixed and assimilated by a specific plant is determined by the light density, because several situations can be seen when the plant is grown the area where the light intensity is not constant this is much explained in the plants light response curve, which shows light compensation point, plant light response area and plants light saturated period where any further increases of the light available to the plant will not result an increase in the amount of the carbon dioxide absorbed from the atmosphere, meaning photosynthetic activities will peak t that point and all the enzymes involved to this process are active. From this concept, the ecologists realized some remarkable differences among the two main pant pathway groups C3 plants, C4plants. Because the carbon dioxide concentration is not the same in these pathways as soon as there are variations in amounts of light available (lower, neutral and higher) the different light amounts are available to the cro p, the growth, development and productivity are highly effected by the light factor. In addition to that, C4 plants showed higher net rate of photosynthesis as a result of light intensity increases than C3 plants. Even though at a very low light intensities C3 plants are more affective and efficiency than C4 plants because of their low compensation points, crops like corn and sorghum full sunlight for photosynthesis while tobacco can tolerate only partial sunlight. Water Water is the most component in the living cell, plants contain nearly 90% of water content , this high percentage enables us to understand the remarkable role of water on the crop growth and development, large quantities of agricultural output all over the world is heavily depend on different types of irrigation, over 1500 million hectares of agricultural land are irrigated every year, the continuously rise of the global temperature is seem to be the highest impact on the irrigated agriculture when considering water (hydrological) cycle. Water in a primary component in plant photosynthesis, the plant respiration, responsible to balance the pressure (turgor) in the plant cell, turgor is required to form the cell shape, tissue firmness and fullness, and ensure cell development. Also water is the place and the solvent where carbohydrates and minerals are transported from the soil and/or leaves to the other parts of the plant. Water treats as a cooling system to regulate the plant temperature specially on the leaf surface through a process called transpiration, water controls the stomata opening and closure, water provides a kind of power to encourage roots to penetrate the soil more in depth and this will enlarge the space that the crop can absorb the nutrients needed for growth and development. One more crucial role is that the water is the medium where biological reactions take place, also water is a component in the organic reactions, and it is used in the cell growth. Amount of water available in the plant compared the atmosphere water content (atmosphere humidity) is the limiting factor of crop photosynthesis, the ratio of the amount of water vapor available in the air to the volume of water that the air can keep at specific temperature and pressure is called relative humidity. Water vapor is the whenever a water molecule leaves from the surface of the ground, it is said to have  evaporated. Each individual water molecule which transitions between a more associated (liquid) and a less associated (vapor/gas) state does so through the absorption or release of kinetic energy. On the other hand, In the hot climate, wind and dry air conditions while there is a moisture stress or what scientifically called water deficit caused by the low water content, in this situation the stomata aperture is dramatically reduced and the photosynthetic reactions are weakened because the activeness and the effectiveness of the enzymes have a direct proportional relationship to the amount of water found from the s urrounding environment and inside the plant tissue and indirectly proportional to the temperature specially the extreme one. Temperature As said in the beginning temperature is important factor to the plant growth, development and yield, since it affects approximately most of the plant processes including germination, photosynthesis, respiration, transpiration and flowering. As the degree of temperature increases this will result an increase to the plant respiration and photosynthesis. Generally in temperate species, the increase in temperature about 10oC (18oF) will cause to the rate of carbon dioxide (CO2) assimilation approximately to double. Furthermore usually plants in the tropical areas require higher temperature degrees to perform successful photosynthetic processes to the possible maximum level that the plants in the temperate areas can generate. Usually, plants differ their temperature requirements for example radish, spinach and lettuce which are cold weather (season) crops germinate at 55oF 65oF best, where crops like petunia, lobelia and tomato which are hot climate crops germinate at about 65oF 75oF best. According to the level of the temperature, plant processes can speed up or slow down the period that each activity completes. For instance, the 18 months that the oil palm plants need to live in the nursery can be reduced to about 10 months when provided higher temperatures from artificial sources. Flowering however, experts in horticulture sometimes relate the length of the day to the temperature to manipulate flowering. For example the combination of short days with low temperature degrees helps cold-season plants to the set the flowers as the case in Christmas cactus, when the temperature levels are in their highest points and the days are in their longest hours the summer (cold-season) crops will bolt as in the case in spinach. In contrast, when the temperature is extremely cold, plants like tomato which is warm climate crops will set their fruits in unsuccessful manner. Temperature influence on biochemical plant processes Biochemical reactions of the plant are directly affected by the temperature through one or two principle functions, an exponentially dynamic increase to the rates of proceeding activities. And sometimes as the climate gets hotter more exponential delay will be experienced resulted by enzymes lost their naturalness. The most important and involved factor is the weather, it is not impossible to rise the quality of enzyme stability so as to avoid losses in their naturalness. The everyday changes on the temperature is called thermo-period the best crop growth occurs when the difference between the day and night temperatures is about 10 to 15o C. under this situation plant build up their food and break down the energy, higher temperatures than that required by the crops cause some crops to photo-respire and the amount of food manufactured by the photosynthesis will equalize the energy used to at that time and carbon dioxide CO2 assimilated will be zero meaning that the crop is in the state of light compensation point. Therefore food molecules synthesized from the photosynthetic activities must overweight the energy that the plant consumes otherwise the plant will grow poorly resulting drops in the ultimate yields. Higher temperatures and their long-term influences on the crop The chronic effects meet the crop growth and development when the temperature is getting higher every day the crop stress will become more serious because of the extreme hot weather. However C4 plants showed a higher net rate of photosynthesis than C3 plants when temperature levels at the surface of leaves were increased. In 1993 Kropff and his colloquies, found that 9% decrease of rice productivity were recorded for every 1o C increase of the temperature, the Intergovernmental Panel on Climate Change (IPCC) coordinating with the Food and Agricultural Organization of the United Nations (FAO), their second evaluation report in December 1995 forecasted that the temperature of the planet will rise about 2 5oC during 21st century and the sea level will grow up about 30 t0 100 cm more, and this higher sea levels can submerge many agricultural areas in the world, these weather conditions will negatively affect the food production in the globe. Carbon dioxide When crops are manufacturing their food through photosynthesis, carbon dioxide is the most component factor importance in that process, plants obtain CO2 from the air through the pore spaces on the surface of the leaf when open, CO2 flow in the plant tissue depends on the carbon dioxide concentration inside the plant and the plants surrounding atmosphere, the carbon dioxide molecules (substances) move inside the plant when the concentration inside is less density than its concentration outside and this is a physical process called diffusion. The carbon dioxide flow in the plant is controlled by the stomata then the pore spaces on the leaf surface are open, and the aperture of the stomata its turn depends on the amount of water available in the guard cells. Overview of carbon dioxide influence on plant growth and development Plants are divided into two main categories according to their response and their first stable product after the fixation of carbon dioxide. The first category is those species whose first stable products after the fixation of carbon dioxide is three carbon molecules and the plants under this group are called C3 plants or C3 pathway. The second group is the species that their first stable products after the fixation of carbon dioxide are four carbon molecules and plants in this group are called C4 plants or C4 pathway, also there are CAM plants, these plants have different character, because the plant here operate fixing carbon dioxide in dark, plants depend on the amount of carbon dioxide accumulated in the leaf in the night. The photosynthetic rates of the plant directly relate to the growing amounts of carbon dioxide until it reaches approximately 700 ÃŽ ¼ mol/mol or higher according to the plant type and other factors. Furthermore photosynthesis always develops with the rise of temperature to optimum levels and after specific maximum level the photosynthesis in C3 plants show decline, as a result of photorespiration process which takes place in the plant. As some scenarios of the world climate change mentions, a global worming is forecasted and that will increase the amount of carbon dioxide available in the atmosphere as well as other gases in the green house. Mean while the amount of rain in many places of the world may also experience changes, generally scientists believe that certain plant species will indicate yield increase especially in C3 plants (C3 pathway includes many important crops like wheat, rice, oats, soybean, pea, peanuts, sunflower and tomato) because of the CO2 increase. However, benefits of increased carbon dioxide concentrations in the atmosphere are limited, because stomata close and photosynthesis stops at CO2 concentrations higher than 0.15%. On the other hand, C4 plants which include coin, sorghum, sugarcane and millet and many other crops are more efficient in higher bright-nesses and higher temperatures than C3 plants even though the reverse is true when light intensity is very low. Soybean responses different amounts of CO2 As IPCC and FAO reported in their second assessment in December 1995, the amount of production harvested from soybean fields was generally increasing by the elevated CO2 levels Allen et al. (1987). The following table shows the percentage increases of soybean yield predicted across selected carbon dioxide concentration ranges associated with relevant benchmark points in time, adapted from Allen et al. (1987). Period of time (years) [CO2] midday Biomass photosynthesis Seed yield Initial Final (Nmd/mol) (% increase over initial [CO2]) IA 17001 200 270 38 33 1700 1973 270 330 19 16 1973 20732 330 660 50 41 1 IA, the ice age is about 13 000 to 30 000 years before present. The atmospheric CO2 concentration that prevailed during the last Ice Age, and from the end of the glacial melt until pre-pioneer/pre-industrial revolution times, were 200 and 270 ÃŽ ¼ mol/mol respectively. 2 The first world energy crises occurred in 1973 when the CO2 concentration was 330 ÃŽ ¼ mol/mol. This CO2 concentration is used as the basis for many CO2 doubling studies. The CO2 concentration is expected to double sometime within the 21st century. Conclusion Crop production and productivity entails the management of production resources, since the world population increases demanding more food and fiber the need of utilizing the sunlight energy, water, temperature and carbon dioxide is important since plants are the ultimate source of energy for all lives on the earth. We humans and other animals cannot utilize the solar energy, only organisms that contain chlorophyll are able, but we are capable to give more attention to the factors that affect photosynthesis. The management, conservation and protection of water, land and atmosphere are the most challenging issues to realize higher and stable crop yields. In the future, the main that the researchers discuss will be to identify and select plant species that have the ability to perform more photosynthesis and carbon dioxide assimilation for higher dry matter production. Also when more is understood from influences of the present climate changes on plant production and productivity, much money, time and effort should be invested to introduce cultivars that can adapt the environment biologically and systems to contribute the management of crop production to create more stable, sustainable and productive agricultural models.

Circulation Systems Over China :: essays research papers

Circulation Systems Over China Introduction: The Earth's atmosphere is in continuous motion: movement which is attempting to balance the constant differences in pressure and temperature between different parts of the globe. It is this motion which carries water from the ocean to the continents to provide precipitation and moves heat energy from the tropical regions toward the poles, warming the high latitudes. It is this circulation which plays a basic part in maintaining a steady state in the atmosphere and generating the climatic zones which characterise different parts of the earth. China, from its latitudinal location, mostly belongs to the mid- latitudes, with a small part to the low latitudes. It is located at south of Siberia and the north of the tropical Pacific. At this distinctive location, the country is affected by the alternate seasonal expansion and contraction of the polar continental highs and tropical maritime air masses, along with the seasonal shifts of the overhead sun. These changes in the pressure systems over Asia generate the unique Asian monsoon circulation which prevails over China throughout the year. Surface Pressure Field and Winds: For any fluid to initiate movements, pressure gradient must exists. Therefore, for a close understanding of the circulation system that operates over China, we should start from discussing the seasonal pressure distribution at sea-level over the Asia-Pacific region, which is the driving force for the air movements in China. Most clearly to be seen, the largest difference in the atmospheric pressure occurs between winter and summer, whereby January and July can be considered as representative months. In January, a typical cold anticyclone with central pressure above 1,040 hectopascals (hPa) developed over mid-Siberia and Mongolia (Mongolian High); while a strongly established cyclone over the north-western Pacific Ocean (Aleutian Low). Since both pressure systems practically lie in the same latitude of 50Â ° to 55Â °N, a steep pressure gradient occurs which produces strong and persistent north- westerlies over Northeast China. A third pressure system which affects China, although limited only to south-eastern China, is the equatorial Low over Australia and New Guinea. The vast territory of East China lies in the middle of the path along which the Mongolian cold air tries to rush southward into the Equatorial Low. Northerly and north-easterly flows prevail over the eastern half of China. As a typical feature, the Mongolian High is only a rather shallow pressure system. It disappears at the 500-hPa level. West China which has a higher elevation, therefore feels little of its influence; Yunnan highlands are even predominated by south-westerlies during most of the winter. The pressure pattern at sea-level during summer differs completely from winter conditions.

Arthur Miller biography Essay

Arthur Miller was born on 17 October 1915, in New York City. He lived in Harlem until he was fourteen. His Dad was a clothes manufacturer but lost all his money in 1929 when the stock market crashed. Due to the economic depression, which followed, when Miller graduated from high school in 1932 there was no money to send him to university. He worked for two years as shipping clerk, earning money to get him to college. He applied to the University of Michigan in 1934 and graduated from there in 1938. He worked in a Navy Yard while writing for the radio. His first successful stage play was All My Sons which opened in 1947 and later a film was made of it. Following this was the even more successful Death of a Salesman, which opened in 1949. These plays were seen as an attack on capitalism and during the McCarthy era of the 1940’s and 1950’s there was a lot of hysteria surrounding the spread of communism. Senator Joe McCarthy was very anti-communist and was adamant that any communist activities in America should be stomped out and the perpetrators jailed. Although this seemed a good idea to some, McCarthy’s policy was you either confess to be a communist, or give names of communists, or you would go to jail. Due to All My Sons and Death of a Salesman being seen as an attack on capitalism, Miller was summoned before the House Un-American Activities Committee that had been in operation since 1938. He was told to confess to signing his name on various petitions that the court had received or he would be jailed. Arthur Miller linked the activities of the Committee to the Salem witchcraft trials in which a few adolescent girls accused people of Salem of witchcraft. If these people did not confess to witchcraft then they would be hanged. From this he was able to write the play, The Crucible. The Crucible is about a young girl named Abigail who is in love with a married man named John Proctor. Abby and some other girls confess to compacting with the devil and are seen as saints as they start naming people who they claim to be witches. Proctor is determined to stop them and he with some others try to oppose authority to uncover the truth. Miller has used John Proctor as metaphor for himself.
