Immigration to America after the Civil War Essay

Immigration to America after the Civil War - Essay Example Immigrations to the United States after the Civil War had many economic benefits and a few negative implications to the country. Labor was at the center of focus after the abolition of the slave trade. An aberration from the trend seen in 1860, the number of workers compared to the total population rose from 33% to 40%, this represented growth by a factor of 2.7 between 1870 and 1920 (Walton & Rockoff 319). This prompted need for labor that ended up facilitating migration of people to the United States. The lives of the people who worked as slaves were fully transformed since there was no more forced labor. On the other hand, the large-scale farmers had a difficult moment adjusting to the new system of operations. This led to failure of some and rising of small-scale producers, who took advantage of the labor boycott by the slaves. The deficit created in terms of labor attracted foreigners who came to America in large numbers. In addition, the situation was aggravated by other extern al factors as the Irish Potato Famine in Ireland. The rise in population because of immigration acted as a catalyst to the rise of the rapid industrialization experienced between 1877 and 1900. The number of immigrants rose to more than seven million during the period. This was accompanied by a tremendous increase in population from 49 million in 1880 to 76 million in 1900 (White 1). The immigrants occupied most parts of America except the southern parts that were fully occupied by American farmers and industrialists. Many industries came up while those affected by the war restructured prompting the demand for additional labor. New production processes were initiated and research was intensified in order to facilitate industrial development. By 1900, many industries stood tall in provision of quality goods and services. This enhanced competition and trade (White 1). Increasing population facilitated a change in the demand and supply dynamics. The increased population provided a broa d market for goods and services, a factor that made it possible to increase the supply. In order, to take care of the supply needs individuals and corporate emerged with solutions to handle the increased supply. There was need for shelter that facilitated initiation of housing projects, need for food that boosted agriculture, the need for clothing facilitated the revamping of cotton farming and establishments of ginneries among other establishments. This demand created high production that facilitated trade within the country as well as opened new frontiers of business especially in Europe (White 1). The immigration rate was a blessing in disguise, since some of the immigrants helped reconnect America with their mother countries hence facilitating knowledge sharing and trading activities. Surplus production increased tremendously. Immigrations to the United States triggered economic changes that were politically motivated. It is worth noting that during the Civil War, there was a gr eat rift between the people of the southern parts of United States and the federal government under Abraham Lincoln. The people of south had an ideological difference with the leadership of the federal government since they wanted to retain slave trade (Digital History 2). Immigration facilitated an anti-democratic movement that was meant to put restriction on voting rights. The movement

Postfeminism and the Future of Feminism Essay Example | Topics and Well Written Essays - 1750 words

Postfeminism and the Future of Feminism - Essay Example The definition of feminism may vary, as the view concerning it may be directly associated with the prevailing ideologies within the society. For example, a patriarchal society influenced by the mass media might understand that feminists are anti-male or are the ones seeking the opportunity to let the women be equal to men. Feminism in this context seems to be a movement against men. According to Hooks, a society founded by Christian culture may continue to believe that women should be under the authority of men, and so they will be ruled over and continue to be submissive (Hooks 2; Shaw and Lee 33). Understanding feminism on this context may be tempting for us to believe that it is about women’s quest to be equal with men. However, Hooks believes that feminism should be defined as a â€Å"movement† to stop â€Å"sexism, sexist exploitation and oppression† (Shaw and Lee 33). From this definition, Hooks tries to emphasize that the problems lie within the actual sex ist actions or thoughts and they are what the feminist movement should need to eliminate. Hooks just wants to correct the popular thought about feminism and its high association with the belief that it is against-the-men movement or women move to be equal with men.   It is at this point that there is a great chance for somebody to develop a theory out of it if exploration and analysis have to be initiated. In fact, one would be able to gain social, cultural, economic and political perspectives by studying feminism, by which one should understand the quest for social justice as the main motivation of the movement to end sexist oppression (Haslanger, Tuana and O’Connor). What is postfeminism? Postfeminism in contrast, tries to define feminism as hopelessly outmoded in the contemporary society as it contains discourses or ideological beliefs trying to make us believe that equality has been achieved (Ringrose 1; Shaw and Lee 15). Postfeminism therefore still defines feminist pe rspective, but the differences start from its associated criticism against feminism that is said to be simply no longer in use. For instance, postfeminism places women as the primary benefactors of globalization taking place in the twenty-first century (Ringrose 3). At this point, it may potentially appear that postfeminism is still a form of feminist movement, but it is placing a different context in it as it tries to position women on top in today’s post-modern world, providing the basis that a woman indeed has achieved the equality she deserves to obtain. This is quite interesting and we might be able to appreciate this point further if we try to take a look at the actual role of the women, their status and the level of achievements they might have acquired and the actual similarities or dissimilarities of opportunities they might have experienced before and in today’s society.

Importance of Strategic Planning and Management

Importance of Strategic Planning and Management Strategic management involves decisions concerning what a company might do, given the opportunities in its environment; what it can do, given the resources at its disposal; what it wants to do, given the personal values and aspirations of key decision makers; and what it should do, given the ethical and legal context in which it is operating (Dobson). Organizations need to know where they are heading to and a firm concept of the kind of business it is in. An organizations product-market scope specifies the particular products or services of the organization and the growth vector is the direction the organization is moving in terms of its current product-market scope. Strategic management is an art and science that must be studied by top management and it involves formulating, implementing and evaluating the cross-functional decisions that have been created so that an organization can achieve its objectives. The organization identifies its objectives, acquire the resources needed to i mplement the policies and strategies to achieve its goals. In order to be successful, strategic management synthesizes the activities of the different sectors of the business such as sales, marketing, production, etc. so that organizational goals can be achieved. Also, strategic management is a continuous process of assessing the business, the industry it belongs, its competitors, for the improvement of the organization. According to Carter McNamara, Strategic planning determines where an organization is going over the next year or more and how its going to get there. (McNamara 2008). The strategic planning process is organization-wide, or it can be focused on a major function. The major activities of the strategic planning process include strategic analysis; setting strategic direction; and action planning. Small business owners need strategic planning because it involves figuring out where the business is going with the aim of achieving overall success and at the same time, pinpoint strategic objectives. Owners of small businesses must give time to look for ways to grow and increase turnover. Most big businesses have used strategic planning when they were still new and small businesses. Strategic planning and business strategy are essential to achieve the goals of the business and without strategic planning and decision making, no business can head forward over the long term. Strategic demands the owners own thoughts and ideas and owners must make it as a major concern. His/Her personal investment in strategic planning is essential and fundamental to make the business to grow and improve the way the business operates and without strategic planning, the business will likely stumble into one problem to another. Therefore, small business owners must consider strategic planning frequently and regularly as it is essential to long term success. The four functions of management in relation to the creation and implementation of an organizations strategic plan are as follows: planning, organizing, leading, and controlling. This paper is going to analyze an external IT company that has been assigned and contracted to take over the internal IT functions of an organization, particularly, the desktop support department. The goal of the external IT Company is to offer the highest quality service with an equally high financial return rate. In the planning stage, the company has to analyze the needs of the organization in terms of technology such as hardware types to support, peripherals, and other various office related equipment. The number of customers impacts the number of support staff needed and the skill levels required. The next phase is organizing and the company is going to reduce the number of their desk side support team for the purpose of minimizing expenses but they have to assign a technician to build an operating syst em, customize it so that the security needs and standards of the organization are met. The next phase is leading and its purpose is to channel the behavior of the personnel so that the organizations mission and objectives are accomplished. In the IT Company, they need to establish good relationship with their staff, give good compensation and benefits, provide them with the best training, promotion, and others so that they will be motivated and become more effective and contribute to the success of the organization. The last function is controlling which refers to the process of establishing the performance standards according to the companys objectives, comparing and taking preventive or corrective action as necessary. The controlling function involves evaluating and reporting the actual job performance of their staff. It is important that these points be studied and further corrective and preventive actions can be decided. In solving performance problems, there is a need for manag ement to higher their standards, speak to the employee on any problem that hinders him/her to work excellently, and check any other problems that may affect performance. Effective and efficient management leads to success, the success where it attains the objectives and goals of the organizations. (Pakhare, J. 2007). In achieving the ultimate goal, management has to be creative in solving problems in all the four functions.

Lincolns Legacy :: essays research papers

Lincoln's Legacy A legacy is something that is passed down from a predecessor. Lincoln's legacy is the teachings that he had wanted all of us, as American citizens, to live by. In the Gettysburg Address, Lincoln explained what our responsibilities as American citizens are. His concepts tie all off U.S. history together and aid the prosperity of our country. In the Gettysburg Address, Lincoln stated that all men are created equal. He was restating the beliefs of Thomas Jefferson when Jefferson wrote the Declaration of Independence. Lincoln was trying to explain to us that unity plays a major role in our lives. Just as Jefferson stated many years previously, we must treat all men as our brothers in order to keep the American society united. Lincoln also stated that a great civil war is something that is very difficult for a nation to endure. The Constitution states that we must create and maintain a more perfect union. That is impossible when we are fighting against ourselves. Lincoln said that "A house divided against itself can not stand." This is what James Madison, "the father of the constitution," meant in the constitution. We must compromise to solve our disagreements and keep our country together. The idea that many men had died for our country and that we should not forget them was strongly emphasized in he Gettysburg Address. In the Bill of Rights it is conveyed that no person should be deprived of their basic rights. These men that died in order that we could all be sovereign, and that nobody could own anyone else, were deprived of everything when their lives were taken. It is our responsibility to never forget what they have so bravely done for us.

Science in Shelleys Frankenstein :: Frankenstein Essays

Science in Shelley's Frankenstein    In Shelley's Frankenstein, it's interesting to use the text to ask the question, whose interest's lie at the heart of science?   Why is Victor Frankenstein motivated to plunge the questions that bringing life to inanimate matter can bring?   Victor Frankenstein's life was destroyed because of an obsession with the power to create life where none had been before.   The monster he created could be seen as a representation of all those who are wronged in the selfish name of science.   We can use Shelley's book to draw parallels in our modern society, and show that there is a danger in the impersonal relationship that science creates between the scientist and his work.   It seems to me that Shelley was saying that when science is done merely on the basis of discovery without thought to the affect that the experimentation can have, we risk endangering everything we hold dear.      Ã‚  Ã‚  Ã‚  Ã‚   When describing the monster he had created, Frankenstein says: No mortal could support the horror of that countenance.   A mummy again endued with animation could not be so hideous as that wretch.   I had gazed on him while unfinished; he was ugly then; but when those muscles and joints were rendered capable of motion, it became a thing such as even Dante could not have conceived. (Shelley, 235)    This was Victor's response to the reaching out of the monster towards Victor on the night of his creation.   Victor, who for months had worked on this creation, was suddenly confronted with the results of his scientific pursuit.   He had labored night and day in an effort to do something that had never been done by man before.   He had figured out the scientific way to bring life to that which was dead, so he blindly went forth and did it.   He never really stopped to think what the consequences of his action might be.   He knows that the creature he is making is ugly, but he never wonders what will happen to the creature after he is brought to life as a result of that ugliness.   The monster is made oversized so it's easier for Victor to work on him, yet no thought is taken about how the creature might feel about such a form.

Airfield lighting

Decennial sensors detect movements of aircraft and there vehicles on the ground. The signals from individual lights and sensors are communicated via FALL and are comprehensively visualized for the operators in the tower through an ALAS. FALL enables the controllers to optimize the use of the entire airfield lighting system: through flexible control of each segment of the runway, taxiway and apron circuits, every component and individual lamp is exactly controllable.As such, FALL provides excellent tools to perform control of aircraft ground movements: taxiway routing, Stoppard control, runway incursion detection are now available for the operators in the tower. Safety of air traffic movements and number of slots per day are significantly increased with this modern and reliable control system. Using the power supply series circuit for reliable and high-speed communication between substation and individual lamps, FALL detects and supervises the actual status of each lamp and provides c omplete detailed information to the operational control station.FALL continuously monitors all lamps controlled via the system and identifies a lamp failure immediately, indicating the exact position of the failed lamp. As a result, the need for regular visual inspections is reduced and overall maintenance performance can be improved. In order to prevent collisions on the reside movement area, CIAO prescribes the implementation of an (Advanced) Surface Movement Guidance and Control System) – (A)SMOCKS is a modern control and monitoring system for the guidance of aircraft on the ground.The solutions offered by Siemens Intelligent Traffic Systems Airfield meet all legal and operational requirements in this field of application. Thanks to sophisticated navigational aids for air traffic control, aircraft can take off and land under almost all weather conditions. However, when traffic on the ground is lowed down, high-volume airborne operations are put in Jeopardy: Visibility cond itions of less than mm generally delay aircraft ground movements and reduce the total capacity of the airport.SUMS identifies each aircraft, provides continuous surveillance and monitoring of taxiing traffic; determines conflict-free taxiway routes automatically and uses visual signals to guide aircraft and vehicles reliably. And in case of route deviations, it warns pilots or drivers immediately. The comprehensive SMOCKS control and monitoring functionality provides controllers with tools to enhance airport safety, efficiency and availability – under all visibility conditions.Tower ALAS Airfield Lighting Control and Monitoring Systems Airfield Lighting Control Systems (ALAS) allow air traffic controllers (TACT) to monitor and operate a range of lighting functions from the control tower, at the same time providing them with valuable feedback on the performance status of system lighting equipment. Surface Movement Guidance and Control System CIAO has specified the provision of (advanced) surface movement guidance and control systems (A-)SMOCKS to avoid collisions on the ground. Siemens/DAB is doing its part to help airports to fulfill these requirements.In the late asses the problems of transition from the new precision radio instrument approach aids to the final, visual approach at night or in reduced visibility much exercised civil aviation. Various high-intensity approach lighting systems were developed to ease the transition from instrument to visual flight. In 1949 three competing systems – a British one (the Calvert system), a French one (a form of displaced Calvert system) and an American one (the Slope Line system) were presented to CIAO. Because each system had its supporters among the CIAO members, CIAO ended up recommending that any of the three systems could be adopted.Independently, and before the CIAO decision, DACCA engineers had also been studying the problem of approach lighting and had concluded that the British ‘Calvert' s ystem was superior. A trial installation was installed on Session's Runway 08 toward the end of 1951. This trial proved successful and the system was commissioned for operational use in 1953. The following information about the Calvert cross bar lighting system is based on an article High Intensity Approach Lighting by S W Hart (DACCA Sectional Airways Engineer) which appeared in the Civil Aviation Joanna, the Dacca house publication, Volvo 1, No 3, March 1951.In 1946 Mr. E S Calvert of the Royal Aircraft Establishment, Breakthrough, was requested by a UK Ministry of Civil Aviation Airfield Lighting Committee to investigate the problem of approach lighting and establish the general principles involved. Calvert tackled the problem by attempting to ascertain the visual and mental processes by which a pilot lands an aircraft. He then developed a theoretical model by which different lighting systems could be compared, and tested his theoretical results using simulation.Culvert's line of reasoning led him to the conclusion that to provide smooth transition room instrument to visual flying without optical illusions, and to provide sensitive and natural indications which could easily be interpreted by the average pilot, the approach lighting pattern should consist of a centre line of light with horizontal bars basic elements – a line of lights leading to the runway threshold, and horizontal lights to define the attitude of the aircraft. Calvert placed much stress on roll guidance compared with the Americans who, up to that time, had completely neglected it.He was the first to realism that it was easy to confuse lateral displacement with angle of ann.. The Calvert system does not indicate a defined glide path, but the widths of the horizon bars are such that, if a pilot maintains a glide that will take him to the correct touch down point, each bar will appear to be the same width as the previous one as it disappears under the nose of the aircraft. Distance is i ndicated by using single lights in the centre line to indicate 1000 Ft or less from the threshold, double lights for 1000-2000 Ft and triple lights for 2000-3000 Ft.It is interesting to note that the basic form of the Calvert cross bar lighting system still forms the basis for high- intensity approach lighting systems today. Diagrams above: With horizon bars the pilot can see if he is on an even keel (left) or banked right wing down to turn on to the centre line (right). Below: A modified form of the basic High Intensity Approach Lighting system is used on some capital city precision approach (ILLS) runways, in this case on Melbourne/Utilitarian's Runway 27.The main difference is the larger array of lights Just prior to the threshold. Runway Edge Lights are used to outline the edges of runways during periods of darkness or restricted visibility conditions. These light systems are classified according to the intensity they are capable of producing: High Intensity Runway Lights (HIRE) Medium Intensity Runway Lights (MARL) Low Intensity Runway Lights (LIRA) The HIRE and MARL systems have variable intensity controls, whereas the Liars normally have one intensity setting.Runway Edge Lights are white, except on instrument runways where yellow replaces white on the last 2,000 feet or half the runway length, whichever is less, to form a caution zone for landings. The lights marking the ends of the runway emit red light toward the runway to indicate the end of runway to a departing aircraft and emit green outward from the runway end to indicate the threshold to landing aircraft. Lighting (ARC) or Pilot Activated Lighting (PAL), is a technical system by which aircraft pilots can control the lighting of an airport or airfield's, approach lights, runway edge lights, and taxiways via radio.PC systems are most common at non- towered or little-used airfields where it is not economical to light the runways all night every night nor to maintain staff to turn the runway lightin g on and off as needed. PC enables pilots to control the lighting only when they require it, thereby saving electricity and reducing light pollution. If the airfield supports PC, the pilot test the radio to the ARC frequency for the airport, which is often, but not always, the same as the UNISOM/ACTA frequency (e. . Smiths Falls-Montague Airport hosts separate Unisom and ARC frequencies). The systems are then typically operated by performing a series of clicks with the radio microphone talk button. PC systems most often have three settings: Low intensity: Three clicks within seven seconds Medium intensity: Five clicks within seven seconds High intensity: Seven clicks within seven seconds When the lighting system is activated, a 15-minute countdown starts, after which the sights turn off.While the lights are still active, whenever a lighting command is issued, whether it changes the lighting intensity or not, the 15-minute countdown is reset. At some airfields, special lights may bli nk for ten seconds to warn pilots before the lights shut off. When using PC, it is very highly recommended that aircraft on final approach to the airfield issue a fresh lighting command even if the lights are already on (especially if the lights were activated by another aircraft). This is so that the lighting does not go off by surprise at a critical moment (such as when crossing he runway threshold).The Visual Approach Slope Indicator (VASS) is a system of lights on the side of an airport runway that provides visual descent guidance information during the approach to a runway. These lights may be visible from up to eight kilometers (five miles) during the day and up to 32 kilometers (20 miles) or more at night. Contents [hide] 1 Types 1. 1 Standard VASS 1. 2 API (Precision Approach Path Indicator) 1. 3 PASS' (Pulsating Visual Approach Slope Indicator) 1. 4 Trio-colored VASS 2 Mnemonics 3 Reference 4 See also 5 External links [edit] Types Standard Visual Approach Slope IndicatorBas ic visual approach slope indicators consist of two sets of lights. One set marks the start of the runway, while the other is set up some seven meters (twenty feet) along the runway. Each set of lights is designed so that the lights appear as either white or red, depending on the angle at which the lights are viewed. When the pilot is approaching the lights at the proper angle, meaning he is on the glide slope, the first set of lights appears white and the second set appears red.When both sets appear white, he is flying too high, and when both appear red he is flying too low. This is the cost common type of visual approach slope indicator system. [edit] API (Precision Approach Path Indicator) Main article: Precision Approach Path Indicator Precision Approach Path Indicator consist of four sets of lights in a line perpendicular to the runway, usually mounted to the left side of the runway. These have a similar purpose to basic visual approach slope indicators, but the additional light s serve to show the pilot how far off the glide slope the aircraft is.When the lights show White- White-Red-Red the aircraft is on the correct glide slope for landing, usually 3. 00. Three red lights (White-Red-Red-Red) indicate that the aircraft is slightly below glide slope (2. 80), while four red lights (Red-Red-Red-Red) indicate that the aircraft is significantly below glide slope (3. 50). Most large airports utilize this system. Although most airports use a API based on a 3. 00 glide slope, some airports may use a glide slope as great as 4. 50 in order to have proper obstruction clearance. Edit] PASS' (Pulsating Visual Approach Slope Indicator) This is a single light next to the runway. The signal format is solid white when established on the proper descent profile, and solid red when below the proper scent profile. An actively pulsing red or white light when well above or well below allows the pilot to determine his position in the signal format and what corrective action is n eeded to return to the proper descent profile. [edit] Trio-colored VASS This is a single light that appears amber above the glide slope, green on the glide slope and red below it.It is rarely used, partly because pilots who are unfamiliar with them have been known to misinterpret the lights, causing them to ‘correct' in the wrong direction. [edit] Mnemonics Older Visual Approach Slope Indicator Pilots often use mnemonics to help them remember basic information. In English, the following are common: Red over white, you're all right. White over white, you're out of sight. Alternative: White over white, you'll fly all night. Alternative: White over white, you're high as a kite. Alternative: White over white, you remain in flight. Red over red, you're dead.Alternative: Red over red, watch your head. Also Red red you're dead Red and white you're alright White and white you're as high as a kite Runway End Identifier Lights (REEL) are installed at many airports to provide rapid and p ositive identification of the approach end of a particular runway. The system consists of a pair of synchronized flashing lights located laterally on each side of the runway threshold. Reels may be either unidirectional or unidirectional facing the approach area. They are effective for: Identification of a runway surrounded by a preponderance of other lighting.Identification of a runway which lacks contrast with surrounding terrain. Identification of a runway during reduced visibility. An approach lighting system, or ALLS, is a lighting system installed on the approach end of an airport runway and consists of a series of lighters, strobe lights, or a ambition of the two that extends outward from the runway end. ALLS usually serves a runway that has an instrument approach procedure (PAP) associated with it and allows the pilot to visually identify the runway environment once he or she has arrived at a prescribed point on an approach.The runway lighting is controlled by the air traffi c control tower. At uncontrolled airports, Pilot Controlled Lighting may be installed which can be switched on by the pilot via radio. In both cases, the brightness of the lights can be adjusted for day and night operations. A key ingredient of all Approach Lighting Systems in the US is the Decision Bar. The Decision Bar is always located 1000†² from the threshold, and it serves as a visible horizon to ease the transition from instrument flight to visual flight.It also is situated such that at Decision Altitude, the Decision Bar is Just appearing to pass under the cowling of the plane. Approach Light Systems are designed such that they allow the pilot to quickly and positively identify visibility distances in Instrument meteorological conditions. For example, if the aircraft is at the Middle Marker, and the Middle Marker is located 3600†² from the threshold, the Decision Bar is 2600†² ahead. If the reoccurred calls for at least 1/2 statute mile flight visibility (roug hly 2600†²), spotting the Decision Bar at the marker would indicate enough flight visibility to continue the procedure.In addition, the shorter bars before and after the Decision Bar are spaced either 100†² or 200†² apart depending on the ALLS type. The number of short bars the pilot can see can be used to determine flight visibility. Approaches with lower minimums use the more precision 100†² spacing systems for more accurate identification of visibility. Several ALLS configurations are recognized by the International Civil Aviation Organization (CIAO); however, non-standard ALLS
