Biomedical Engineering Prosthetics of the Future

Biomedical Engineering: Prosthetics of the future Take a second, and imagine your life as a teenager, fresh out of college with, aspiring to get a degree in whatever your heart desires. You’ve got lots of ambition and potential. The world is at your fingertips; you can do anything you set your mind to. But one day, tragedy strikes and the unthinkable happens: you lose a limb. Why is not important, but what the future entails is. Let’s say this limb is your right arm, the one you have used all your life to write, eat, type and play the guitar. Now let’s change the scenario a little bit. Instead you’ve lost your legs in a horrific car accident where both were crushed under the weight of the dashboard as your car collided with the 4x4 in front of you. You wake up the next day in the hospital groggy, barely remembering what happened. Shock is the only thing running through your mind the moment you look down to see your legs missing. Your brain thinks they’re still there because yesterday you were just getting out of bed for your morning jog. All that remains are the stubs where your legs used to be and the unbearable thought of being confined to a motorized chair for the rest of your life. But what if life doesn’t have to be this way? What if there is a solution that can make your life whole again, gift you the limbs you once lost and offer you the confidence you once had to accomplish anything and everything you set your mind to.

Dawn Schultz Essay Example For Students

Dawn Schultz Essay Religion in the U.S. Midterm Project02.25.99You are the light of the world. A city on a hill cannot be hidden. -Matthew 5:14John Winthrop: In seventeenth-century England, there was no such thing as freedom of religion. Sincere Christians had only two choices: either work to reform the Church from within, or break off from the Church and reject its authority. Those who wanted to break off from the Church were known as Separatists; the Puritans were not Separatists. We believed that breaking off was a very serious matter, and should only be considered as a last alternative. We did not want to be disloyal to the Crown. But as the Church grew more hostile towards our Puritan ideas, it became clear to me that I could do nothing to reform the Church from within. At the age of forty-two, after a very painful struggle, I decided that the only real choice was to take my family and move away from England. I sold all of my possessions and arranged to move my entire family to the dangerous and rugged New World. On A pril 7, 1630, I left my wife and eldest son behind because she was expecting another child. It was painful to separate, but I had no choice. While aboard the Arabella, I kept a diary of events and thoughts. I dreamt of America, this wonderful new land, to become a city on a hill as Jesus described to his apostles in the Holy Gospel. The first year of our settlement in New England was one of misery. I kept the firm belief in the guiding hand of the Lord, despite the death of three of my children and the near failure of the colony. I reflected on the words I had spoke to nearly five thousand passengers aboard the Arabella: . . .the eyes of all people are upon us, so that if we deal falsely with our God in this work we have undertaken, we shall be made a story throughout the world; we shall shame the faces of many of Gods worthy servants, and cause their prayers to be turned to curses upon us, until we are consumed out of the good land to which we are going. . .The religious tradition of the Puritans was my life; it consumed my life and filled every aspect of my career both in my mother country and in my home in the New World. The teachings and philosophies of John Calvin stood at the base of what we, as Puritans, believed. As our name indicates, our sole mission was to purify the Church; to return to the primitive Church that our Lord and Savior Jesus Christ instituted. We dedicated our lives to the works of the Lord, and made every attempt to keep in accordance with the teachings of the Bible. Our services were simple, for prayer and faith needs no decoration. It is our belief in God that is the most glorious. Of course, there was a very clear hierarchy that served the congregation. Our most faithful and well-established men served these positions. As our colony progressed, a need for a government grew, and so I took part in the governmental procedures.I served as governor of our colony called Massachusetts; however, long before I took that role in colony life, I had a deep understanding of Gods divine purposes for the colony. Bostons center of life was the church during the years I lived there. While on my journey to America, I wrote a sermon called A Model of Christian Charity, in which I outlined the purposes of God for New England. I described my vision of a harmonious Christian community whose laws and government would logically proceed from a godly and intentional arrangement. I also envisioned Gods plan for the whole nation that would arise out of the colonies. Our citizens would be free to act and choose according to free will, and yet still remain dedicated to a lawful social order. Liberty was a very important issue to me; my yearning for religious freedom inspired me to start anew in the colonies. My ideals about the New World helped to set the foundation for a land that would eventually gain great power. I was part of the initial movement that created an influx of many others seeking that same religious freedom. The Puritans w ere not influenced by American culture; instead, we created American culture.The ethics and ideas put forth by our simple and faithful society stood as the basis for the government and operations of American society. As I look back on the history of this country, I still see the influence of our modest community in lawmaking and moral issues. As the founder of the Puritan movement in the New World, I envisioned a near utopia for those who sought to make the Church a clean and holy institution. I thought that the legacy of the Puritans would be long-lasting and prosperous. Although our society blended among others that came to the colonies, our ideas and morals have survived throughout the years. A negative light has been attached to the Puritan standards of living in modern-day American society.Today, Americans only grasp that Puritans were overworked, stern, negative individuals. They do not remember that we were filled with an intense love of God, so powerful that we bravely ventu red into the wilderness and risked all of our earthly possessions as well as our lives. It is because of our spirit that Americans have a place they can call home today, filled with freedoms that my fellow colonists and I had only dreamed of. Perhaps in this new millenium there will be a newfound respect for the ideals and beliefs that we held so dear. Americans might realize once again their purpose: to be that city on a hill. God has called us to be a light, and we are still His light. That mission will follow us for all of eternity. For it is written; we must heed His call to be the New Israel. .u6e54ba430c39443a12f6e7d565f7f3f3 , .u6e54ba430c39443a12f6e7d565f7f3f3 .postImageUrl , .u6e54ba430c39443a12f6e7d565f7f3f3 .centered-text-area { min-height: 80px; position: relative; } .u6e54ba430c39443a12f6e7d565f7f3f3 , .u6e54ba430c39443a12f6e7d565f7f3f3:hover , .u6e54ba430c39443a12f6e7d565f7f3f3:visited , .u6e54ba430c39443a12f6e7d565f7f3f3:active { border:0!important; } .u6e54ba430c39443a12f6e7d565f7f3f3 .clearfix:after { content: ""; display: table; clear: both; } .u6e54ba430c39443a12f6e7d565f7f3f3 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u6e54ba430c39443a12f6e7d565f7f3f3:active , .u6e54ba430c39443a12f6e7d565f7f3f3:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u6e54ba430c39443a12f6e7d565f7f3f3 .centered-text-area { width: 100%; position: relative ; } .u6e54ba430c39443a12f6e7d565f7f3f3 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u6e54ba430c39443a12f6e7d565f7f3f3 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u6e54ba430c39443a12f6e7d565f7f3f3 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u6e54ba430c39443a12f6e7d565f7f3f3:hover .ctaButton { background-color: #34495E!important; } .u6e54ba430c39443a12f6e7d565f7f3f3 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u6e54ba430c39443a12f6e7d565f7f3f3 .u6e54ba430c39443a12f6e7d565f7f3f3-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u6e54ba430c39443a12f6e7d565f7f3f3:after { content: ""; display: block; clear: both; } READ: Globalization And Sustainability Essay God has provided the Way for us; He has never faltered.

Love Song Of Prufrock Essays (1369 words) - Chapbooks,

Love Song Of Prufrock The ironic character of "The Love Song of J. Alfred Prufrock," an early poem by T.S. Eliot (1888-1965) in the form of a dramatic monologue, is introduced in its title. Eliot is talking, through his speaker, about the absence of love, and the poem, so far from being a "song," is a meditation on the failure of romance. The opening image of evening (traditionally the time of love making) is disquieting, rather than consoling or seductive, and the evening "becomes a patient" (Spender 160): "When the evening is spread out against the sky / Like a patient etherized upon a table" (2-3). According to Berryman, with this line begins modern poetry (197). The urban location of the poem is confrontational instead of being alluring. Eliot, as a Modernist, sets his poem in a decayed cityscape, " a drab neighborhood of cheap hotels and restaurants, where Prufrock lives in solitary gloom" (Harlan 265). The experience of Prufrock is set against that of unnamed "women" (13), collectively representing womankind. Their unattainable status is represented by their constant movement- they "come and go"- and their "polite chitchat about Michelangelo, who was a man of great creative energy, unlike Prufrock" (Harlan 265). We cannot imagine that they would listen to any love song by Prufrock, any more than they would find his name or his person attractive. "A man named J. Alfred Prufrock could hardly be expected to sing a love song; he sounds too well dressed" (Berryman 197)."J. Alfred Prufrock" indicates his formality, and his surname, in particular, indicates prudery. The powerful metaphor, a visual image of the "yellow fog" (15) in the fourth stanza, represents the jaundiced environment of the modern city, or Eliot's "infernal version of the forest of Arden" (Cervo 227). The image is ambiguous, however, because Eliot also makes it curiously attractive in the precision he uses in comparing the fog's motions to that of a cat who "[l]icked its tongue into the corners of the evening" (17). We also hear the fog, disquietingly, in that image, in the onomatopoeia of "licked." Repetition of "time", in the following stanza, shows how the world of Prufrock's being is bound to temporality. "Prufrock speaks to his listeners as if they had come to visit him in some circle of unchanging hell where time has stopped and all action has become theoretical" (Miller 183). "Time" is repeated, several times, but it is not only its inescapable presence that Eliot is emphasizing, but also the triviality of the ways in which we use it; "the taking of a toast and tea" (34). The melancholy of Prufrock's situation begins to emerge when he speaks of his experience of failures in love and life. The initial vitality of his invitation to go out into the evening is now replaced by images of the many evenings he has known, with their same disappointing conclusions. This meditation expands to include "mornings, afternoons" (50) - all of his life, in other words - which, in a famous image, he has "measured out with coffee spoons" (51). The emphasis on "I" in the poem, which we would expect in a dramatic monologue, is also typical of Romanticism, with its celebration of the ego. Again, in this poem, Eliot is pointedly unromantic, as the "I" that is revealed is fit not for celebration but for ridicule, especially when Prufrock shows that he has been repeatedly diminished, even reduced to a laboratory specimen, by others' evaluation of him. It is little wonder that his self-confidence, the essential quality of a successful lover, has been shattered. It is women, of course, who have delivered this judgement on Prufrock. He finds them powerfully attractive, with "[a]rms that are braceleted and white and bare" (63), but we notice that this image - like the eyes, earlier, that "fix you in a formulated phrase" (56) - does not indicate a whole person, but rather a fragment of a human being, almost lifeless, like "[a]rms that lie along the table" (67). We may be critical of Prufrock, but the objects of his desire are scarcely more desirable. The criticism broadens to encompass a society, even civilization, and Prufrock becomes a type of human being - modern urban man, perhaps - not merely himself. The poem is haunted by the refrain referring to the women. Prufrock is taking himself and us on a quest in pursuit of them, "Let us go then, you and I" (1). It is a Romantic image, but Prufrock's quest is frustrated by the modern setting and by his unheroic qualities. Prufrock's

The objectives of an individual are linked to the objectives of team, as when the individual being a member of the team, performs well, it will put positive impact on the moral of the team. When each individu al in a team performs well, it will be easier to achieve the objectives of the team and consequently, the working relationship of individuals within a team will help the organization to achieve its objectives. Being a potential manager or a leader of team, I would focus on working with each individual in my team separately. In my opinion, it is essential for me to discuss work related issues and solutions with every individual of my team so that the team members can get motivated and work towards achieving the organizational objectives. Selection of Individual and Team Objectives Individual objectives are selected after the analysis of each individual’s personal competencies and skills, whereas the team objectives are selected after considering the nature of work that is required to be performed by the team. There are numerous reasons for setting different objectives for a team and individual to achieve. Bering on a managerial position, I would set different objectives for my team and the individuals who are member of my team. Considering the fact that organizational objectives becomes difficult to achieve due to the knowledge, skills and abilities that are required from a single person. Provided that I would select a team of diversified individual, it will provide me a chance to fill the gaps left by one individual, by utilizing the skills of other individual who have skill to fill that gap. Areas of Individual and Team Responsibility To achieve organization’s objectives, a manger must create a distinctive line between the responsibilities of team and the individuals within that team. If I were the manager, I would have based my leadership style prescribed by John Adair (Adair 2012). As proposed by Adair, an action centered leader will identify aims and vision of a group, gather resources, create a plan, allot responsibilities, set standards and control the flow of activities. Being a manager of a team, I would be responsible for establishing ob jectives and reaching to a point where my team members agree with my work method and than work towards achieving the objectives. On the other hand, being a manger for individuals in my team, I would assess personal skill, problems, highs and lows of every individual and than assort individual responsibilities accordingly. Need to Trust and Support An environment where every individual of a team have a right to speak and share ideas, develops self-confidence and intrinsic motivation among the individuals. As being a manager, I would pay especial consideration towards winning trust of my team and individua

What is information technology How is it changing our working lives Essay

What is information technology How is it changing our working lives - Essay Example sts that Information Technology is here and it will stay on for a very long period of time, until it gets replaced by some other advanced technology in the times to come (Wehn 1998). What is most important to decipher on the part of a world citizen is that Information Technology has played such a vital role in changing the lives of the people that it is almost impossible to negate the positives which have been brought about with the passage of time. Also what could be expected from Information Technology in the future remains a mystery because the marvels embedded within the domains of the same remain to be seen in the times to follow. Information Technology is an enabling force because it makes people think of the possibilities and eventualities that can arise from its incorporation within the systems and procedures of the present times. The manner in which Information Technology has come about as a facilitating agent has made even the staunchest critics realize that its due role is immense and Information Technology will be able to pave the way between the link that remains in a person’s needs and his desires. The gadgets, electrical appliances, cell phones, laptops, etc are all the marvels of Information Technology and many other things are also bracketed under the same heading (Wulf 1995). Information Technology makes use of the communication mechanisms that are there amongst the people and their desires so that their most potent needs could be fulfilled in the most feasible manner. If these needs are not properly addressed, there is enough room to make amends so that the ranks of Information Technology are taken care of in the most apt manner possible. Also what summarizes the debate of Information Technology stems from the fact what researchers have been able to devise with the passage of time and what they expect from the same in the times to come (Diwan 2002). These researchers and scientists believe that Information Technology is a force that will

Examine and explain the contrasting principles unerpinning the Essay

Examine and explain the contrasting principles unerpinning the organisational structures and practices of the French communist and socialist parties in the 1970's - Essay Example During the 1980s the Socialist Party became the party of the Left in France, electing Francois Mitterrand to two terms during that time. In order to explain these developments one must look to the previous decade for the social, political, and organizational practices and beliefs that facilitated this change in the ideological left in France. An examination of the theoretical and ideological apparatuses that precipitated this political shift along with a presentation of cultural and political events that led to a realignment of political strategies of the two parties will be followed by an inquiry into the organizational and leadership practices and beliefs of the two groups. The subsequent analysis of the ebb and flow of the respective fortunes of the PS and PCF should reveal that the Political Left in France has operated under a "Coalition as Rivalry"2 paradigm to the ultimate benefit of the PS and the seemingly irrecoverable detriment of the PCF. Forming out of the Section Francaise de Ilnternationale Ouvriere (SFIO) in 1905, the Socialist Party was cobbled together with an uneasy mix of Marxists, members of workers parties, revolutionaries and reformists.3 The uneasiness of this arrangement eventually led to a splintering of the "feeble" alliance and at the 1920 Congress of Tour, what was to become the PCF was formed.4 The rather hard ideological line of the PCF illustrated by the slogan, "sovietization à ¡ outrance" is indicative of the affiliation that French Communists had at the time with Soviet Politburo.5 The Socialists and Communists did briefly come together in an unofficial capacity, along with the radicals in a mid-1930s movement known as the Popular Front. That coalition was interrupted by WWII. After WWII, much of the left was united against Gaullism though nevertheless splintered over the issue of Algerian Independence. The start of the Fifth Republic saw perpetuation of the orthodox

Role Of Analog Communication In Daily Life Computer Science Essay

Role Of Analog Communication In Daily Life Computer Science Essay This term paper is based on the analog communication and its role in daily life. Analog communication is performed on continuous signal. In electronics, a signal is an electric current or  electromagnetic fieldused to convey data from one place to another. Signal Sampling Quantizer Encoder Output Sampling: Quantising: Encoding: Signal is divided into two parts: Analog or Continuous signal: A  continuous signal  is a varying quantity whose domain, which is often time, is a  continuum. The function itself need not be  continuous. Digital or Discrete signal: A  discrete signal  is a  time series  consisting of a  sequence  of quantities. In other words, it is a time series that is a function over a  domain  of discrete integers.   2. Communication: Communication is a process of transferring information from one entity to another.   Information source transmitter channel receiver Noise destination Block Diagram of communication system modulating signal transducer electrical amplifier modulation Output signal demodulator receiver channel noise Block Diagram of analog communication system Basics of communication: Channel is of two types: Guided or wired Non-guided or non-wired Guided is of three types: Twisted pair Coaxial cable Optical fibre Non-guided is divided into two parts: Microwave Satellite Modes of Communication: Simplex Half-duplex Full-duplex Elements of communication system: Modulation: Change in one of the parameter of carrier wave in proportion to the instantaneous value of the modulating signal. Continuous Signal Amplitude modulation Angle modulation Frequency modulation Phase modulation Modulation Index: The  modulation index of a modulation scheme describes by how much the modulated variable of the carrier signal varies around its unmodulated level. It is defined differently in each modulation scheme. m=Em/Ec where m is the modulation index. Em=(Vmax-Vmin)/2 Ec=(VMax+Vmin)/2 Amplitude Modulation (AM): Change in amplitude of the carrier wave in proportion to the instantaneous value of the amplitude of the modulating signal. Amplitude modulationis a method used in electronic communication which is most usually used in transmitting information by means ofradio carrier wave. AM works by changing the power given to the transmitted signal in the message being sent. Example,changes in the signal strength can be used to reproduce the sounds to be reproduced by a speakeror to specify the light strength of television pixels. Compare it with  frequency modulationwhich is also commonly used for sound broadcasting in which thefrequency  is variable; and phasemodulation often used in  remote controls in which the  phase  is variable. AM is often used to refer to themedium wave  broadcastband. In telecommunications,  frequency modulation  (FM) conveyssine formation  over acarrierwave  by varying its  frequency  compare this with  amplitude modulation, in which theamplitude  of the carrier is varied while its frequency remains constant. In  analogapplications, the instantaneous frequency of the carrier is directly proportional to the instantaneous value of the input signal.   Advantages of Amplitude Modulation: There are several advantages of amplitude modulation It is very easy to implement it can be demodulated using a circuit containing of very few apparatuses AM receivers are very inexpensive as no particular components are required. AM has benefits of ease, though it is not the most effectiveway to use, both in terms of the quantityof space or spectrum uses and the way in which it uses the power that is transmitted. This is the reason why it is not extensively used these days both for broadcasting and for two way radio communication. Even the long, medium and short wave broadcasts will eventuallychange because of the truth that amplitude modulation is subject to much higher levels of noise than other modes. Its easiness and its wide usage means it will be hard to change rapidly and it will be in use for many years to come. Frequency Modulation (FM): It is the process of variation in frequency of the carrier wave in proportion to the instantaneous value of the amplitude of the modulating signal. While changing the amplitude of a radio signal is the best method to modulate it, it is not the only way. It is also possible to vary the frequency of a signal to give frequency modulation. Frequency modulation is widely used on frequencies above 30 MHz, and it is mainlyknown for its use for VHF FM broadcasting. It is not easy as amplitude modulation;however frequency modulationdeals with some dissimilarbenefits. It is able to provide immediate interference free response and this is the reason it isassumed for the VHF sound broadcasts. These transmissions could offer high fidelity audio, and this is the reason, frequency modulation is much more prevalent than the older transmissions on the long, medium and short wave bands. In addition to its extensive use for high superiority audio broadcasts, FM is also used for a variety of two way radio communication systems where amplitude modulation is a failure. Whether for fixed or mobile radio communication systems or for use in moveable applications, FM is widely used at VHF, mobile radio. Advantages of frequency modulation, FM: FM is used for a number of reasons and there are numerousbenefits of frequency modulation. Some of the benefits of frequency modulation are as under: Resilience to noise: Frequency modulation has elasticity to signal level variations. The modulation is carried as there are disparities in frequency. This means that any signal level variations will not disturb the audio output, on condition that that the signal does not fall to a level where the receiver cannot handle. As a result it makes FM perfect for mobile radio communication applications including more general two-way radio communication or movable applications where signal levels are likely to vary much. The additionalbenefit of FM is its elasticity to noise and interference. It is for this reason that FM is used for high superiority broadcast communications. Easy to apply modulation at a low power stage of the transmitter:  Ã‚   Frequency modulation is linked with the transmitters. It is probable to relate the modulation to a low power stage of the transmitter and it is not essential to use a direct form of amplification to escalate the power level of the signal to its ultimate value. It is possible to use efficient RF amplifiers with frequency modulated signals:  Ã‚   It is possible to use non-linear RF amplifiers to amplify FM signals in a transmitter and these are more effective than the linear ones required for signals with any amplitude disparities. This means that for a given power yield, less battery power is necessary and this makes the use of FM more possible for portable two-way radio applications. Frequency modulation is widely used in various areas of radio technology including broadcasting and fields of two way radio communication. In these applications its specificbenefits can be used to good consequence. In spite of these changes, FM will continue to be in use for many years to come as there are many advantages of frequency modulation for the areas in which it has addedaimportanthold in recent years. Phase Modulation (PM): Change in the phase of the carrier wave in accord to the instantaneous value of the amplitude of the modulating signal. Advantages of phase modulation: Phase modulation demodulation is less complicated as compared to Frequency modulation. Phase modulator is used in shaping velocity of moving target by removing Doppler information. Doppler information needs steady carrier which is probable in phase modulation but not in frequency modulation. Role of analog communication: Analog communication plays a very vital role.Either in the form of AM,FM or PM. It is used in audio, video, telephony, wireless communication, radar, emergency services, etc. Audio AM broadcast radio which sends voice or music in the Medium Frequency Radio Spectrum which ranges from 0.3MHz to 3MHz. AM broadcast uses amplitude modulation in which high sounds at the microphone roots wide variations in the transmitter power while the transmitter frequency remains constant. Transmissions are regularlyaffected by static since lightening and other some sources of radio add their radio waves to the one upcoming from the transmitter. AM radio stations are the original broadcasting stations. They are aform of connection of radio waves by changing the amplitude of the carrier signal in proportion to the instantaneous value of the amplitude of the transmitted signal. AMs simple signal can be detected with simple apparatus which turns into sound. If a signal is strong enough then there is no necessity of power source, Another advantage to AM is that it uses a narrow bandwidth than FM. FM broadcast radio transmits voice and music with high fidelity than AM broadcast radio. In frequency modulation loud sounds at the microphone causes the frequency of the transmitter to varyfurther than the transmitter power stays persistent. FM is transmitted in the Very High Frequency radio spectrum ranging from 30MHz to 300MHz. FM needs extra radio frequency zone than AM and at high frequency more frequencies are accessible and there are additional stations each one sending more information to the station. And when shorter VHF radio waves usually act like light which travels in straight line so the response range is usually limited to 50 to 100 miles. During higher atmospheric situation, FM signals are echoed back to Earth by the ionosphere layer which outcomes in Long distance FM response. FM receivers are subject to capture outcome which causes radio to receive the strongest signal when many signals are on the similar frequency. FM receivers are reasonablyprotected to lightening and spark interference. Aviation voice radios use VHF AM. AM is used so as to obtain multiple stations on the same channels. Aircrafts fly high adequately so that their transmitters can be received thousands of miles away. It uses VHF. Marine voice radios use narrowband FM in the VHF spectrum for very smaller ranges and use AM in the shortwave HF radio spectrum extending from 3MHz to 30MHz for very long distances. FM Subcarrier services areminor signals transmitted associated along with the main program. Special receivers are necessary to operate these services. Analog channels may comprisesubstitute programming, such as reading services for the blind, background music or stereo sound signals. In some countries, FM radios automatically retune themselves to the matching channel inanother district by using sub-bands. Government, police, fire and commercial voice facilities use narrowband FM on distinct frequencies. Fidelity is sacrificed to use a lesser range of radio frequencies, typically five kilohertz of aberration rather than the 75 used by FM broadcasts and 25 used by TV sound. Civil and military HF voice services use  shortwave  radio to communicate withships at sea, aircraft and remote settlements. Most use  single sideband  voice which uses a smaller amount of bandwidth than AM. SSB sounds like ducks quacking on an AM radio. This also makes the transmitter about three times more influential, because it doesnt need to communicate the unused carrier and sideband. Telephony Cell phones transmit to a native cell transmitter/receiver which associates to the public service telephone system through an optic fibre or microwave radio. When the phone leaves the cell radios zone, the central computer shifts the phone to a new cell. Cell phonesinitially used FM. There are many cellphone service providers in India nowadays. The main among them are: BSNL Airtel Vodafone Idea Aircel Videocon Tata Docomo Tata Indicom MTNL MTS Satellite phones come in two types:  INMARSAT  and  Iridium. Both types provide world-wide coverage. INMARSAT uses geosynchronous satellites, with directed high-gain antennas on the vehicles. Iridium provides cell phones, except the cells are satellites in orbit. Satellite phone communication is not available in public domain in India. It is used by the defence services. The main companies that provide the satellite phones in India are: Motorola Siemens GE Satellite phone communication can be provided in the public domains as the media persons in the remote areas etc. But it needs a special licence from TRAI. Video Television transmits the picture as AM and the sound as FM on the identical radio signal. Digital television encrypts three bits as eight strengths of AM signal. The bits are directed out-of-order to cutdown the effect of gusts of radio noise. Even if any data could be transmitted, the standard is to use  MPEG-2  for video, and five CD-quality (44.1 kHz) audio channels (centre, left, right, left-back and right back). With all this, it takes only half of the bandwidth of an analog TV signal because the video data is generallycompressed. India saw the advent of satellite communication in 1995. But it was limited to cable operators till 2007. But then, satellite communication stepped up inot DIRECT TO HOME channels. These providers are: DishTV Reliance BIG TV Airtel Digital TV Tata Sky. Videocon d2h Navigation All  satellite navigation  systems use satellites with accuracy clocks known as precision clocks. The satellite communicates its position and the time of the broadcast. The receiver listens to four satellites and can figure out its location as being on a line that is tangent to a circular shell around each satellite, determined by the time-of-flight of the radio signals from the satellite. Loran  systems also used time-of-flight radio signals, but from radio stations on the ground. VOR  systems (used by aircraft), have two transmitters. A directional transmitter scans or spins its signal like a lighthouse at a fixed rate. When the directional transmitter is facing north, an Omni-directional transmitter pulses. An aircraft can get readings from two VORs, and locate its position at the intersection of the two beams. Radio direction-finding is the oldest form of radio navigation. Before 1960 navigators used movable loop antennas to locate industrial AM stations near cities. In some cases they used marine radiolocation beacons, which share a range of frequencies just above AM radio with amateur radio operators. GPS i.e. Global Positioning System is in use from past decade. Vehicles using navigation with the help of GPS. GPS is being installed in recent luxury cars and in many business class vehicles. It relies on high frequency radio signals from satellites in space. Vehicles having GPS navigation systems can travel in some situations where they may lose the signal for some time. It usually provides accurate navigation information. The companies that provide the Navigation systems in India are: Map My India Nokia OVI maps Garmin GPS systems. Radar (Radio Detection and Ranging) Radar detects things at a distance by bouncing back radio waves from them. The delay caused by the echo measures the distance. The direction of the beam determines the direction of the reflection. The polarization and frequency of the return can sense the type of surface. Navigational radars scan a wide 2 to 4 times per minute. They use very short waves that reflect back from earth and even stone. They are common on commercial ships and long-distance commercial aircraft. General purpose radars generally use navigational radar frequencies, however modulate and polarize the pulse so that the receiver can decide the type of surface of the reflector. The best general-purpose radars distinguish the rain of heavy storms, as well as land and vehicles. Some can superimpose sonar data and map data fromGPS  position. Search radars scan a wide area with pulses of short radio waves. They usually scan the area 2 to 4 times a minute. Sometimes search radars use the  Doppler Effect  to separate moving vehicles from confusion. Targeting radars use the same principle as search radar but scan a much smaller area. Weather radars resemble search radars, however use radio waves with circular polarization and a wavelength to reflect from water droplets. Some weather radar use the  Doppler  to measure wind speeds. This is how radar screen looks Emergency services Emergency position-indicating rescue beacons (EPIRBs),  emergency locating transmitters or  personal locator beacons are small radio transmitters that satellites can use to locate a person or vehicle need rescue. Their purpose is to help and free people in the first day, when survival is possible. Data (digital radio) Pioneers such as Marconi used the oldest form of digital broadcast which was Spark Gap Telegraphy. The operator could send messages in Morse coding just by reviving a rotating communicating spark gap b pressing the key. Simple spark gap generates a hiss when rotating commutator generates a tone in the receiver, same from the static. Spark gap transmitters are now banned because their transmissions span is several hundred MHz which is a waste of both radio frequencies and power. Its just inefficient and uneconomical. The next progress is to use continuous wave telegraphy (CW) in which pure radio frequency is produced by a vacuum tube electronic oscillator which is switch on and off by a key. A receiver having a local oscillator will heterodyne with pure radio frequency creating a whistle like audio tone. Less than 100Hz of bandwidth is used by CW. Amateur radio operators still use CW. On-off keying of a carrier should be known as Interrupted Continuous Wave or ICW. Radio teletypes usually run on short-wave (HF) and are much acceptable by the military since they generate written information with no skilled operator. They convey a bit as one of two tones. Groups of five or seven bits turn into a character printed by a teletype. From about 1925 to 1975, radio teletype was how on the whole commercial messages were sent to less industrial countries. These are still used by the military and weather services. Aircraft use a 1200 Band radio teletype service over VHF to send their ID, altitude and position, and get gate and connecting-flight data. Microwave dishes on satellites, telephone exchanges and TV stations frequently use  quadrature amplitude modulation  (QAM). QAM sends data by altering both the phase and the amplitude of the radio signal. Engineers like QAM because it packs the most bits into a radio signal. Usually the bits are sent in frames that repeat. A special bit pattern is used to position the beginning of a frame. Systems that need consistency or which allocate their frequency with other services may use corrected orthogonal frequency-division multiplexing or  COFDM. COFDM breaks a digital signal into countless several hundred slower sub-channels. The digital signal is frequently sent as QAM on the sub-channels. Modern COFDM systems use a small computer to make and decode the signal with  digital signal processing, which is more flexible and far less expensive than older systems that implemented separate electronic channels. COFDM resists fading and ghosting because the narrow-channel QAM signals can be sent bit by bit. An adaptive system or one that sends error-correction codes can also defy interference, because most interference can change only a few of the QAM channels. COFDM is used for  Wi-Fi, some  cell phones,  Digital Radio Mondiale,  Eureka 147, and many other local area network, digital TV and radio standards. Most new radio systems are digital, Digital  Satellite Radio,  Digital Audio Broadcasting. Heating Radio-frequency energy generated for heating of objects is generally not intended to radiate outside of the generating equipment, to prevent interference with other radio signals. For heating food and other eatables, microwave ovens use strong radio waves. It is a general misconception that the radio waves are tuned to the resonant frequency of water molecules. The microwave frequencies used are actually about a factor of 10 below the resonant frequency. Diathermy  equipment is used in surgery for sealing of blood vessels. Induction  furnaces are used for melting metal for  casting. Mechanical Force Tractor beams: There is a small electrostatic and magnetic force being exerted by radio waves which is enough for the performance of station-keeping in microgravity environment. Spacecraft propulsion: Propulsion method for an interstellar probe called Starwisp is proposed with the help of powerful radio waves which has a radiation pressure. Since the radio waves are long so the probe could be very light weighted metal mesh and hence it attains high accelerations. Other Amateur radio  is a pastime where enthusiasts who purchase or build their own equipment and use radio for their own enjoyment. They may also provide an emergency and public-service radio service. This can be of large use, saving lives in many instances. Radio amateurs are able to use frequencies in a big number of finebands all over the radio spectrum. Radio amateurs use all forms of programming including outdated and new ones. Several forms of radio were pioneered by radio amateurs and afterwards became commercially significant including FM, SSBAM, and digital packet radio and satellite repeaters. Individual radio services such as  Citizens Band Radio,  Family Radio Service,  Multi-Use Radio Service  and others offer simple, short range message for persons and small groups without the simplicity of licensing. Wireless energy transfer: Many schemes have been proposed which transmits power using microwaves and its techniques have been confirmed.These schemes consist ofsolar power  stations  in orbit beaming energy down to worldwide users. Radio remote control: Radio waves are used to transmit data to remote point as is done in some early forms of guided missile, TV remotes and a range of model boats, cars and airplanes. Remote controlled equipments which are used in large industries mostly use digital radio techniques for safety purposes and reliability. Such equipments are cranes and switching locomotives. Conclusion: From the one-way communication analog communication has now reached to two-way communication. From wired system to wireless communication. With the help of analog system one can find direction easily. It helps in spacecraft propulsion. Analog systems are inexpensive in many cases. It uses less bandwidth. Accuracy of analog systems is more. As the world is leaving from Wires to Wireless, The technology and swiftness or speed of wireless communication is also going leaps and bounds. The wired set-up often goes too crowded and offers obstruction to mobility needs of the users i.e. the wired system is not portable. If at all it is then it is very complicated. With wired Networks, although security characteristics and speed are however not matched by the wired networks, nevertheless the incapability to being flexible is what causes the wireless mediums to gain additional public awareness. Analog communication plays a vital role in our day to day life. It is used in many fields today and is growing each day. Its multi-tasking made the work easier. Just by changing the frequency range, it can be used differently. With the help of analog signals, the boom of communications is rising.

Slavery in America :: Slavery Essays

Slavery in America By 1850, ninety-two percent of all American blacks were concentrated in the South, and about 95 percent were slaves. Pre-civil war slaves in America went through a great deal of turmoil and discontent in the South. Slavery has had a huge effect on our country. Many slaves were beaten to death and some did not survive the ruff life of slavery. Slavery then went on to cause the War between the North and the South known as the â€Å"Civil War†. In 1916, a Dutch ship brought twenty enslaved Africans to a Virginia Colony at Jamestown. Slaves were sold all over the United States to work on small farms and plantations. The slaves worked hard day in and day out to finish their jobs. Slave owners would whip and beat the slaves that would not work right or that tried to escape the plantation. Many times on a small farm the master would be in the field watching the slaves. Usually on larger farms the master would hire an overseer to make sure the slaves work and do not try to escape. (Slavery in America)   Ã‚  Ã‚  Ã‚  Ã‚  Slaves were taken from several areas of Africa such as Timbuktu, Benin, and Fut Tur. The African west coast was a very dangerous place during the triangular slave trade. First, the slave traders leave Europe and are directed to African West coast. Then they go from African West coast to West Indies or America. Finally they sail home from America. A complete trip lasts about 12 months. Slaves were brought by ships from Africa to be sold in America. (Pre-Civil War)   Ã‚  Ã‚  Ã‚  Ã‚  Runaway slaves used the Underground Railroad to escape slavery. They used the North Star for guidance to the northern United States. They would travel through waterways, swamps, forests, mountains, and back roads to escape slavery. Free blacks, Quakers, whites, and Native Americans would also help the slaves escape.   Ã‚  Ã‚  Ã‚  Ã‚  In conclusion I have learned that slaves in the Pre-civil war ear went through a great deal of trial and tribulation.

PACCAR System Lab Essay

1. Why did PACCAR commit such a large amount of resources to electronic systems during the recession? PACCAR decided to commit such a large amount of resources to electronic systems during the recession because they knew it was something they needed to introduce in their company to stay competitive. It also would help their staff with smart technology as it relates to navigation and engine performance. PACCAR knew that with these upgraded systems they could both have better intelligence for their customers as well as better navigation and output readings for their drivers. Even though it was during a recession, PACCAR saw this as an opportunity to do some in house improvements. 2. What are the beneï ¬ ts of PACCAR’s new navigation system and diagnostic system to truck drivers? The benefits of PACCAR’s new navigation system and diagnostic system to truck drivers are abundant. With the new diagnostic system drivers can keep an eye on anything wrong with their truck and with new software updates to only add gauges, it seems like drivers will be able to see a small problem and fix it before it becomes a bigger problem. The new navigation system shows drivers heights of bridges, weight limits on bridges, rest stops, weigh stations, and anything else a driver may need. As we all know it is hard navigating somewhere you’ve never been before. With this navigation system the driver doesn’t have to worry about any height or weight issues because the system knows any restrictions. 3. What are the beneï ¬ ts to PACCAR of collaborating with outside companies in building new systems? Some benefits to PACCAR collaborating with outside companies in building new systems are that they have an already knowledgeable group working on the new systems and that they, in turn, get taught that knowledge and can take on  the responsibility of upkeep and updating the system after it has been integrated. When you are not an expertise in software development and things like that, trying to just do everything in house can be just as, if not more expensive as getting someone to do it that knows what they are doing. Not only that, but if you mess something up, you may not even realize it until it is way too late, causing more problems. Also what better way to learn then from watching and working with someone that is an expert in the field. By gaining all of that experience and know how, PACCAR can now create updates and fix issues on their own without having to outside consult anymore, unless it is necessary. 1. Describe the reasons that Hilton decided to collaborate with IT partners rather than develop its own information systems in house. Hilton decided to collaborate with IT partners rather than develop its own information systems in house because they knew what a huge undertaking developing its own information systems would be. Hilton had different business it needed to deal with and it had no real knowledge of the IT world, so it needed some help. We know it was a huge undertaking because they asked five different companies to run five different parts of their IT. This leaves Hilton the ability to run its business and not have to worry about things like IT. 2. What are the problems associated with collaborating with ï ¬ ve large strategic IT partners? Provide speciï ¬ c examples to support your answer. Some problems associated with collaborating with five large strategic IT partners would be each company has its own strategy. For example, IBM and Microsoft do a lot of the same things, so how does Hilton decide who runs what, or who has power to adjust things over the other. Does IBM run all the data collection and storage with its server knowledge or does Microsoft because Hilton is using their software. At the same time, all of this is done wirelessly, so when there is a problem, who do we contact? The network provider, who is AT&T, or the server provider IBM. It can get tricky, but I am sure Hilton has a team that sorts these type of problems out.

Tess of the DUrbervilles Chapter 35 Essays

Tess of the DUrbervilles Chapter 35 Essays Tess of the DUrbervilles Chapter 35 Paper Tess of the DUrbervilles Chapter 35 Paper 1. When Tess first tells Angel of her confession, he does not seem to comprehend what she has just said. He gets up and stirs the fire; Clare performed the irrelevant act of stirring the fire; the intelligence had not even yet got to the bottom of him. The confession seems so utterly unbelievable to him that he cannot take it in and seems to be in shock, although he just told Tess a revelation of the same sort about himself. This is the first clue that Angel had an idealised version in his head of Tess. When he first speaks he says O you cannot be out of your mind! You ought to be! Yet you are not This shows that he would have, or would rather have, believed that she was mad other than what she had just told him was true. This also shows his disbelief of how she could have done that. He seems to be severely changed after she tells him; His face had withered. His face has physically changed, described as withered as opposed with the readers previous view that he was handsome. This cou ld also indicate that he is not going to act as he was before as he has changed.This is true as the chapter carries on. Tess tells him she has forgiven him, for what is the same or possibly a worse act than what she has done, and when she asks him if he has forgive her, he says: O Tess, forgiveness does not apply to the case! You were one person; now you are another. My God how can forgiveness meet such a grotesque prestidigitation as that! Although he accepts that she has forgiven him for the same thing, he does not forgive her. He believes that what she has done is a lot worse than what she has done. When he says she is a different person, this shows that he thinks that the person he believed was Tess would not have done this, so he says that she must be a different person. He believed too much in his idealised version of Tess that this revelation is too much of a shock to him. Later he repeats; The woman I have been loving is not you. Here it is clear that he was only in love w ith the Tess in his mind, not for her actual self as she loves him.When she starts crying, he is relieved at it. This implies that because she wasnt crying, instead of her being strong as she was, it makes her seem less innocent and vulnerable, but as she does he is glad that she is showing some sense of emotion at the event. He does not know what to do now, which shows he is still in shock. However, it is obvious that he has changed, as he is sarcastic o her, and also starts denoting her because of her class, again showing how he does not believe she is still the woman he loved. He also begins to class her as her DUrberville roots were; Decrepit families imply decrepit wills, decrepit conduct. He is labelling her into all the things he does not like, although he loved everything about her only a few hours ago. He now sees her as something entirely different and changed. At the end of the chapter when she goes to her room, he almost goes in there to speak to her, but he catches a gl ance at an old portrait of a lady from the DUrberville family. He sees this and immediately compares it to Tess, as if this must be how she is; Sinister design lurked in the womans features, a concentrated purpose of revenge on the other sex. Before he had an idealised image of Tess, and now he has adopted an image of Tess that she is evil.2. In chapter XXV Hardy uses different techniques to describe the change in relationship between Tess and Angel. One of the first things he uses is personification of the surroundings in the room, to help explain how the surroundings reflect the change in Angels attitude towards Tess; But the complexion even of external things seemed to suffer transmutation as her announcement progressed. This is talking about how the atmosphere in the room has changed, but also how this reflects the change that Angel has gone through. What before was a happy room is now portrayed has being changed for the worse. In the chapter previous the fire was described as h aving a red-coaled glow. However now it is described as; The fire in the grate looked impish demonically funny, as if it did not care about her strait. The fender grinned idly, as if it too did not care. Here the fire is described as being somehow evil, like an imp or a demon. This is reflecting how Tess and Angels relationship has changed for the worse, but may also be reflecting how angel now views Tess as evil. This is reiterated later when Tesss eyes are said to make his [Angels] flesh creep, and again at the end of the chapter when Angel compares Tess to one of the ancient DUrberville women Sinister design lurked in the womans features.Another feature that seems to have change is that the structure of the text seems to have changed up to now Hardy has been quite descriptive in his writhing, but in this chapter, especially at the beginning, it seems to be more like a dialogue. For example; Clare performed the irrelevant act of stirring the fire. This does not describe him ge tting up or moving around the room. For most of the chapter, it is just dialogue between Tess and Angel. This shows how the atmosphere seems to have changed and also to reflect the drama of what is going on.Both of the descriptions of Tess and Angel have changed Angels face has become withered, and Tesss lips have become pale. This could reflect how Hardy wants the characters to be viewed Angel as not being as virtuous as the reader had first thought, and Tess is portrayed as more innocent because her lips are no longer red. This is also repeated when her mouth is described as a round little hole. This is significant because one of the things that Angel commented on liking about her was her mouth.Right at the end of the chapter Hardy talks about the light. Before in the book he has talked about the light, especially in the morning when Tess has been looking out over the countryside, which always seemed to imply hope for the future, but now Hardy says; The night came in, and took u p its place there, unconcerned and indifferent. This seems to be implying that this is the end of the happiest period of Tesss life, which started with Angel and is now ending with Angel.3. Previously in the book, Angel was seen as being different from his brothers and other men at the time by being open minded and not conforming to contemporary attitudes. However, his reaction to Tesss confession is contradictory to his earlier behaviour, although it is typical of attitudes of Victorian men at the time.After Angel tells Tess of his admission of being with another woman out of wedlock, Tess is relieved because what she did was the same, or even not as bad, as what he did. However, he goes into shock at the reality that she is not so pure, so sweet, so virginal as what he thought she was. This goes back to how he had an idealised image of what Tess was. In those days, it was much more socially unacceptable for a woman to have sex out of wedlock than it was for a man a woman was seen as being the property of the man. Tess also shows this opinion, as she says to Angel; I dont belong to you any more, then. This shows the point that men were seen as the superior and therefore in charge of the women. Another change in Angels behaviour is his view on class.Before, he wanted to marry Tess, even though she was of a lower social class than he was. He even tried to convince his father that a farming woman would be of better aid to him in the running of a farm. However, he is now judging Tess because of her class, as he says; You almost make me say you are an unapprehending peasant woman. Here Angel is being demeaning towards Tess because of her class, which never mattered to him before. This is reflective of contemporary social attitudes at the time, but this shows how changed Angel is because he is now showing beliefs typical of men in that era, whereas before he prided himself on being more open-minded.

How the State Profits from War Essays

How the State Profits from War Essays How the State Profits from War Essay How the State Profits from War Essay One of the most abiding misconceptions in economic science is that war is good to the economic system ( Moffatt. n. pag. ) . This myth was farther perpetuated by the economic expert and New York Times editorialist Paul Krugman. who wrote: Ghastly as it may look. ( the devastation of the World Trade Center ) could even make some economic good†¦ the drive force behind the economic lag has been a dip in concern investing. Now. all of a sudden. we need some new office buildings ( Tracinski. n. pag. ) . Indeed. bad economic sciences reign in minutes of crisis and or terror. when people are despairing for solutions. To rebut the alleged benefits of the War Economy. reviews use the fallacy of the broken window ( Tracinski. n. pag. ) . When a vandal throws a brick through a shop’s window and the shop’s proprietor has to pass. state. $ 200 for the window’s fix. the people will believe that the defacer has given a positive part to society. After all. the fix of the broken window meant an instant encouragement in employment and economic activity ( Tracinski. n. pag. ) . But what these short-sighted citizens didn’t know was that the $ 200 that was spent on repairing the window could hold been used in ventures that might hold advanced the store owner’s endeavor. Unfortunately. advocates of the War Economy assumed that ( since ) a broken window can excite the economic system. ( it must be better ) when literally 1000s of them are broken ( Tracinski. n. pag. ) . For them. wars are important for the endurance of modern economic systems ( Cline. n. pag. ) . War Economy advocates believed that about every industry is involved with supplying goods and services to the armed forces ( uniforms. nutrient. medical specialties. arms fabricating. etc. ) . Hence. should war be eliminated. these concerns. peculiarly engineering and fabrication. will turn up up. Another statement of the angels of the War Economy is that it is the fastest solution to an economic slack ( Moffatt. n. pag. ) . When the economic system is undergoing recession. production is low and people are passing less than usual. But when the authorities goes into war. it will necessitate arms and equipment for its soldiers. Economic activity is hence expected to increase due to the rise both in authorities disbursement and the private sector’s concern minutess with the miliatry. Corporations will scramble for contracts that will let them to provide uniforms. vehicles and bombs to the ground forces. These companies will hold to engage more workers to maintain up with the addition in demand. take downing the unemployment rate in the procedure. There are even some workers who will be employed to replace those who volunteered as reservists abroad. Since the unemployment rate is decreased. consumers will pass more once more. Increased ingestion. in bend. will hike the retail sector. At the terminal of the twenty-four hours. there will be overall economic growing. thanks to the authorities fixing for war. However. critics contended that the above-named jutting economic promotion is at the disbursal of incapacitated civilians from Third World states ( hypertext transfer protocol: //www. unpac. ca. n. pag. ) . In 2002. one-year planetary military outgos were estimated to be more than $ 800 billion ( hypertext transfer protocol: //www. unpac. ca. n. pag. ) . The United States was at the top of this list. passing $ 343. 2 billion annually ( hypertext transfer protocol: //www. unpac. ca. n. pag. ) . Canada earned more than $ 3 million from selling arms in the same twelvemonth ( hypertext transfer protocol: //www. unpac. ca. n. pag. ) . Harmonizing to the United Nations Platform for Action Committee – Manitoba ( UNPAC-Manitoba ) article The Economicss of War ( n. d. ) . a big portion of the economic systems of all of the world’s wealthiest states derives from the sale of weapons ( hypertext transfer protocol: //www. unpac. ca. n. pag. ) . From 1996 to 2000. the US exported $ 54 billion worth of weaponries – 45 % of the entire sum of arms that was exported around the universe ( hypertext transfer protocol: //www. unpac. ca. n. pag. ) . Russia came 2nd at $ 21 billion ( 17 % ) . followed by France ( $ 11 billion or 9 % ) . the United Kingdom ( $ 8 billion or 7 % ) and Germany ( $ 6 billion or 5 % ) ( hypertext transfer protocol: //www. unpac. ca. n. pag. ) . As a consequence. says the United Nations Development Program ( UNDP ) in 2002. 500. 000 firearm-related deceases occur yearly ( hypertext transfer protocol: //www. unpac. ca. n. pag. ) . Each twelvemonth. land mines kill 15. 000-20. 000 kids and grownups ( hypertext transfer protocol: //www. unpac. ca. n. pag. ) . Iraq’s malignant neoplastic disease rates rose to 700 % between 1991 and 1994 due to chemical arms. while 86 million people have perished in belligerencies after World War II ( hypertext transfer protocol: //www. unpac. ca. n. pag. ) . The Iraq war in 2003 was the latest illustration of how the US turned war into a money-making venture. It was rooted in the logic of planetary monopoly capital. specifically American capitalist economy. to spread out into an empire ( Barona. 33 ) . Despite being packaged as a terrorist war. ( to transfuse fear among disparagers ) it was brought approximately by the globalisation policies of American transnational companies. peculiarly the US oil industry and the military-industrial composite ( MIC ) ( Barona. 33 ) . Iraq is one of the world’s biggest oil militias – it. along with other OPEC states such as Saudi Arabia. Iran. Kuwait and the United Arab Emirates. has 79 % of the world’s entire oil supply ( __________ . 16 ) . For the US to hold limitless entree to Iraq’s oil. it merely had to take Saddam Hussein. a steadfast US opposition. from power. Back place. the US economic system was sustained by military disbursement – the injection of fresh capital was necessary to resuscitate an economic system that would go on to deteriorate if left to the free market ( Barona. 33 ) . But the Iraq war proved to be black for the US economic system. The US spends $ 200 million daily merely to be able to go on its military operations in Iraq ( Wolk. n. pag. ) . Even if the US eventually decides to draw its military personnels out of Iraq within another three old ages. entire direct and indirect costs to US taxpayers will probably by more than $ 400 billion†¦the entire economic impact at up to $ 2 trillion ( Wolk. n. pag. ) . Economist and Nobel Prize victor Joseph Stiglitz ( a well-known castigator of the Iraq war ) claimed that the entire cost of US military intercession in Iraq is a staggering $ 1 trillion to $ 2 trillion. including $ 500 billion for the war and business and up to $ 300 billion in future wellness attention costs for hurt troops ( Wolk. n. pag. ) . Stiglitz added that farther disbursals include a negative impact from the lifting cost of oil and added involvement on the national debt ( Wolk. n. pag. ) . These astronomically immense amounts of money came from revenue enhancements – financess that should hold been diverted to basic societal services such as instruction. wellness and lodging. While ordinary American citizens were enduring from the economic calamity brought approximately by the Iraq war. a few persons and corporations cahsed in on the said struggle. In 2007. Lockheed Martin ( the taking arms maker in the US ) had a net income addition of 22 % ( Scheer. n. pag. ) . In the same twelvemonth. the net incomes of its rivals Northrop Grumman and General Dynamics rose by 62 % and 22 % . severally ( Scheer. n. pag. ) . Boeing’s net incomes. meanwhile. increased by 61 % ( Scheer. n. pag. ) . Below are some personalities who were said to hold besides profitted from the Iraq War: a ) Former US President George W. Bush. Sr. – Shareholder and former Senior Advisor in the Carlyle Group. a defence contractor with ties to the Saudi royal household and the Bin Ladens. B ) Former Defense Secretary Frank Carlucci – Member of the RAND Board of Trustees and co-chair of the RAND Center for Middle East Public Policy Advisory Board. Besides the president of the Carlyle Group. degree Celsius ) Former Secretary of State and Secretary of Treasury James Baker – Former Carlyle Senior Counselor. vitamin D ) White House Budget Advisor Richard Darman – Carlyle Managing Director vitamin E ) US Vice President Dick Cheney – Head of Halliburton Co. . an oil endeavor that traded with Libya and Iran through foreign subordinates ( Lynch. n. pag. ) . Thankss to the craze brought approximately by the War on Terrorism and the Iraq war. taxpayers were swindled into funding the War Economy that made millionaires out of Bush and his like. And every bit long as the absurd propaganda of The War on Terrorism and the Iraq war continues to be. ordinary Americans will pass their full lives paying revenue enhancements non for basic societal services. but as a tribute to Bush and his kind for them to be able to populate like male monarchs.

Social & Community Development Research Essay Example | Topics and Well Written Essays - 2000 words

Social & Community Development Research - Essay Example The option of having alternative education programs for prospective delinquent children is something I admire. It was no difficult task choosing my area of research seeing that it has been aptly covered by Cox among other researchers. The research by this particular writer is a bonus for me as it provides a foundation stone for my future research interests. Perhaps the reason for my personal interest in this research area is because I lost an elder brother to jail for delinquency; something that could have been prevented early enough. While searching for this journal, I first developed a search strategy that was very useful in identifying this research. To start with, I first defined the topic that I wanted to cover, or rather my research interest. As stated earlier, my interest in research is in child delinquency. A practical solution to child delinquency is the establishment of alternative schools. In so doing, I came up with the keywords ‘child delinquency’ and ‘alternative schools’. To make my search more wide and varied, I included the keyword ‘assess*’. The asterisk at the end of the word assess was intentional to make the search pick up variations such as ‘assessed’ and ‘assessment’. Since the three concepts, assess, child delinquency and alternative schools are related I used the conjunction ‘and’ between them to ensure the search gave results that had all the three concepts. The work of Cox particularly interested me because of the number of reviews that it had attracted (Conley, 2002, pp. 142). Moreover, the researcher has been involved in other remarkable researches. In particular, his assessment of delinquency related outcomes of alternative education programs stood out because it covered the same field that I was venturing in. The fact that Cox has published those many times (Korn, 1991, pp. 75) makes him an ideal reference point in doing my future research. The main

Classical Image of Education Essay Example | Topics and Well Written Essays - 1000 words

Classical Image of Education - Essay Example Though it defies description and is not easily defined, we know it when we see it as our imagination offers us a clue to its possibilities. Our classical image of education and its definition falls short of the true meaning when it is applied to a lifetime of learning. Typically, an education has been thought of as a specified period of time in which certain subjects are learned to a pre-determined level. Education is sometimes mistaken for the Bachelor's or Master's degree that indicates we have attended school, but it is not an education. Albert Einstein once said, "Imagination is more important than knowledge. Knowledge is limited. Imagination encircles the world". The spark that ignites our imagination is education. The subjects taught in pursuit of these goals give us information and provides us with a key to further learning, but this is not education. Learning to appreciate art, perform logical operations, or the history of rock and roll are interesting to know, but they do not qualify as education. All of these activities and endeavors are simply the tools required to begin to mine an education. Yet, listing all the tools and components involved in making an education would be of no more relevance than calling a list of ingredients a cake. The traditional view of 120 credits, electives, and compulsory courses fails to completely define education. Education is the creation of a task, concept, or belief that we find useful in our life and defines us as a human being. The formal learning that was required to obtain a degree becomes useful as we enter the workplace and begin to assimilate with the culture of our livelihood. Here we learn what is expected of us, what is needed to make progress on a task, and how to complete a workplace function. Logic and art may help us temper the new environment and give us a sense of deeper understanding of the world around us, but the education takes place when we learn to undertake a project and develop the confidence that gives us our self-identity. Information needs to be put to use and contribute to our sense of self-worth to be considered education. In essence, we define education by how education defines us and the way that we define ourselves. Education is part and parcel of the human spirit that drives us to imagine, create, inspire, innovate, and invent. We may have an intricate knowledge of calculus, but in its dormant state it adds nothing to our education. Education is an action word that demands that we act and react to the facts and information we gained from attending school. When we encounter a new situation that requires us to solve a problem we create a solution from the tools we gained from our classroom experience. The innovative experience that we create out of our limited knowledge is the true meaning of education. It is not simply the information or the knowledge that defines us. Education is the inspiration we receive when we put our knowledge into action. When we integrate several fields of knowledge, while we stretch to invent a new process or concept, we can then say that the experience was 'a real education'.

Nazi Leadership Pictured in the Black Book Term Paper

Nazi Leadership Pictured in the Black Book - Term Paper Example In the time of its release, it indeed was the most expensive Dutch film that ever existed as well as the most commercially successful film in the Netherlands. The film stands out more realistic depiction of some history. It has been used to offer the conventional wisdom that the Dutch and the resistance were the heroes while the Germans with the Dutch sympathizers were eventually the villains. Additionally, the film acts as a magnificent cross in the business and art. It has been such an entertaining film that appeals the audience from the professors down to the shop assistants which remains worthwhile for many years. During the final years of the World War II, a beautiful woman singer Rachel Stein finds refuge with the Tsjempkema family in the rural part of the Holland. She waits out the war just like any other Jew in Europe as a popular and a wealthy singer. Separated from the family with some moment away from being captured by the Gestapo, her temporary house is destroyed by the Allied bomber in fire by a German fighter where she is left in the arms of Michel Huisman-Rob a very sympathetic boy who promises Rachel’s safety in the period. The following morning Rob helps Rachel to her contact in the town helping that she will be assisted in finding her family to escape across in the liberated territory (Harris 123). On arrival at home, Mr. Smaal with the wife Diana Dobbleman who is a compassionate lawyer having worked secretly in helping the Jews to escape from Holland, reluctantly arranges that Rachel joins the family and crosses the enemy lines in the allied territory, marking her name i n a little leather notebook. In the period of the dangerous crossing, the German troops ambushed the boat whereby the Nazi kills the boat passengers ruthlessly but Rachel narrowly escapes jumping overboard in a river.

Ideal Renaissance Man Essay Example for Free

Ideal Renaissance Man Essay An ideal renaissance man or woman in the fourteenth and fifteenth century, a time when people aspired to be skilled in numerous areas and humanistic education was customary, meant you would have to stand out from the rest. Pico della Mirandola theories in Oration on the Dignity of Man sum up the ideal Renaissance man. He proclaimed that individuals face no limits to their development except those that are self-imposed (Columbia Electronic Encyclopedia). In theory only one can hinder their own success. The ideal renaissance man had a broad base in knowledge or was highly skilled in the arts, music or literature. Some lived up to being ideal just because they were bold or unique. The ideal renaissance man was respected by his peers and his knowledge and abilities were often required by the patrons of this era. Ingeniously, some individuals happened to be masters of art, engineering, and even anatomy all at the same time. Mostly men, renaissance contributors did not normally encourage women to participate during this time. Women were encouraged to fit the profile of wives and mothers and their political rights at this point were still kind of limited. Nevertheless, there were many that fit the description of an ideal renaissance women. One unique women of this time was Laura Cereta. A writer who struggled with heavy criticism from her cohorts because of her scholarly pursuits. In response to both the men and women who were judgmental of her, Laura wrote two letters â€Å"that were penned to answer both critics: a defense of learning aimed at male humanists and a defense of her vocation directed toward her female critics† (Cunningham 289). Laura’s heated verbiage in these letters won her great recognition and respect. In describing an ideal renaissance man Leonardo Davinchi owned up to that title for his many achievements. He donated to us many chemical theories, the air balloon, the telescope, and trigonometry. He was a plethora of knowledge. He was also recognized for his many works of art known all around the world today, The Mona Lisa and The Last Supper for example. He was diverse in his thinking and saw many of his ideas through. He was a living example and true to Leon Alberti’s (1404–72) quote: that â€Å"men can do all things if they will. † The Renaissance is understood as a historical era of cultural movements. Its contributors are termed â€Å"Ideal Renaissance Men and Women† for making it possible. Even so, they continued to pursue more knowledge and abilities. For this, they were ideal renaissance people of their time.

Horror and Suspense in Bierces Work Essay -- Ambrose Bierce Short Sto

Horror and Suspense in Bierce's Work A novel is divided into different chapters and usually has different plots to focus on. In a novel there are lots of characters and the time scale is constantly changing throughout. Because there is more than one theme and there are different messages coming across of combined themes, makes the novel denser and more complicated to understand and to take in all the description. Ambrose Bierce wrote a lot of short stories and some we have studied and analysed. In a short story there is usually only one plot and the event usually carries on in the same setting. There are usually a couple of characters and one hidden message which makes the short stories more to the point and very direct. As I was analysing the short stories by Bierce, I realised that most of the characters in them were male and most of the stories contained physicians. Looking over Bierce’s background I was able to see that Bierce was brought up in a male dominated area where women were secondary characters. I assume this is why Bierce’s main characters are male and the female characters only play a secondary part in the setting. He had a son who committed suicide and a son who drank himself to death. I think this is why Bierce put physicians in most of his stories. The physicians don’t know when the victims of the stories are about to die, so maybe Bierce could relate to these because no physician could warn him about his sons dying. Throughout Bierce’s stories he has a good use of horror and suspense. He does this by being very concise and to the point. He also makes more impact on us as he uses pathetic thalacy. He does this by describing the weather in such a way that reflects on the mood o... ...he misery of others.’ This ties in with us laughing at the misery of Henry Armstrong. Others find it horrifying as they would be terrified of being buried alive and in those days it was quite common for medical students to dig up the corpses. This also ties in with Bierce’s definition of a grave, which I also found in ‘The Devil’s Dictionary.’ A grave is a place in which the dead are laid to await the coming of the medical student.’ Reading these stories of Bierce’s I found to be very interesting and thoroughly enjoyed. I think it is clear that Bierce was trying to scare a lot of people and effectively did as the description, the language used, the mixed feelings it sends out and the context of his writing creates a lot of horror and suspense. Some may say that Bierce is sick others say that he is very intelligent. Bierce- brilliant or disturbed?
