Dbq Colonial New England and Chesapeake Regions - 891 Words

DBQ: Colonial New England and Chesapeake Regions The Chesapeake and New England regions were settled by people of English descent, but by 1700, they had become two distinctly different societies. They had evolved so differently, mainly because of the way that the settlers followed their religion, their way of conducting politics and demographics in the colonies. Even though the settlers came from the same homeland: England, each group had its own reasons for coming to the New World and different ideas planned for the colonies. On his way to the New World, aboard the Arabella in 1630, John Winthrop, Puritan leader of the Massachusetts Bay Colony, spoke of the plan that he had in store for the colony. He preached that there would be†¦show more content†¦In the Chesapeake region, the settlers came for entirely different reasons; they didnt come to form a community in the New World, they came looking for gold. Everything in VirginiaÂâ€"the colonist, the politics, and the societyÂâ€"was based on profit, unlike in the New Eng land region, it was an every-man-for-himself society instead of a brotherly community. In History of Virginia, Capitan John Smith wrote that the colonist main reason for coming to the New World was to Â… dig gold, wash gold, refine gold, load goldÂ… Another reason the Chesapeake region was so different from the New England region was because the basis of the settlement was to find gold and ship it back to Mother England, some of the colonist did not plan to stay in the New World either; they were only attracted by the economic benefits. In the Ship List of Emigrants Bound for Virginia, it is reported that the settlers that are coming into the New World are still in allegiance with the Anglican Church and the King. This shows that the colonists are not seeking religious freedom or striving to become a city upon a hill, but rather seeking economic opportunities. Another significant point that arises in the document is that the population of men is about six times that of women; not to mention that the women are listed separate from the men.

Kurt Vonneguts Opinions Expressed in Player Piano, Cats...

Kurt Vonnegut’s Opinions Expressed in Player Piano, Cat’s Cradle, and Slaughterhouse-Five Every so often, a person comes along and encompasses the meaning of a generation. This person will capture everything people want to say, and then word it so well that his or her name becomes legendary. The sixties was an era with many of these people, each with his or her own means of reaching the people. Kurt Vonnegut, Jr., armed with a typewriter and a motive, was amongst those that defined the sixties. Like other notable figures of the sixties, his strong opinions moved the people. Vonnegut’s opinions cover a wide range of topics and address almost all aspects of society. He represented the flower children of the sixties, as he†¦show more content†¦He attended Cornell University from1940 to 1942, and the Carnegie Institute of Technology in 1943. From 1942 to 1945, he served in the United States infantry in Europe during World War II (Ethridge 1-4: 970-971). According to Stanley Schalt’s book Kurt Vonnegut, Jr., Vonnegut was captured at the Battle of the Bulge and then sent to Dresden to work in a factory producing vitamin supplements for pregnant women (n. pag.). He was awarded the Purple Heart for his efforts. Vonnegut then came home, where he continued his college education by attending the University of Chicago from 1945 to 1947. He married Jane Cox in 1945 and eventually fathered three children, their names being Mark, Edith, and Nanette. After the war, he was a Chicago City News Bureau Police Reporter in 1947. Before he became a writer, he also worked with Public Relations for General Electric in Schenectady, New York from 1947 to 1950 (Ethridge 1-4: 970). In 1950, Vonnegut decided to become a writer, with his first novel, Player Piano, being published in 1951. He would later go on to write works such as Canary in a Cat House (1959), Mother Night (1961), Cat’s Cradle (1963), God Bless You, Mr. Rosewater (1965), Slaughterhouse-Five (1969), and Breakfast of Champions (1973). His most renowned work, Slaughterhouse-Five, is as close to an autobiography as he comes. In Slaughterhouse-Five, Vonnegut writes a novel based his experience as a prisoner of war

9/11 Terrorist Attacks Essay Example

9/11 Terrorist Attacks Essay An Analysis of the 9/11 Terrorist Attack On September 11, 2001, 19 Al Qaeda terrorists hijacked four United States commercial airliners travelling from the east coast to California. The hijackers forcibly took control of four planes. Two planes were purposefully crashed into the World Trade Center (WTC) in New York City. The third aircraft was flown into the Pentagon building in Washington DC. The fourth plane landed in a Pennsylvania field. All of the people on board the aircrafts were killed. There were 2996 people killed including the hijackers and the airline passengers and the victims on the ground in New York and Washington DC. A total of 836 first responders also died as the result of their efforts to rescue people in the WTC before it collapsed (The National Commission on Terrorist Attacks, 2004). According to the US government, 9/11 was an act of war. The United States government, state and local agencies mobilized during the disaster. Victims in New York and Washington DC were taken to area hospitals for medical treatment. As the result of the terrorist attack, the government instituted a series of measures that changed the United States policy towards terrorism and homeland security. The aftermath of the World Trade Center and Pentagon attacks left the country in a state of shock. The report on 9/11 details the steps taken by the government during the attack on the WTC and the Pentagon. The attacks caused wide-spread confusion among air traffic controllers and news organizations. During 9/11, the government used radio and television to communicate with people and inform them of the situation. Grisly scenes of the wreckage were replayed in the media. Government and state agencies communicated with each other via radio and walkie talkie.

Because of the possibility of more 9/11 style attacks, the government immediately invoked SCATANA, Security Control of Air Traffic and Navigation Aids. United States (US) airspace was closed to all aircraft except for military aircraft, and the US border was closed to international travel. Planes that were in flight were ordered to land immediately. International planes that were travelling to the United States were forced to land in Mexico or Canada. Because the 9/11 terrorists targeted the White House and the Pentagon, the federal government created a contingency plan for the continuity of government in cases of emergency. In addition, a plan for the evacuation of the top American political leaders was developed and implemented in case of future terrorist attacks (The National Commission on Terrorist Attacks, 2004). On September 11, 2011, the government declared a state of emergency. The United States military and the National Guard were mobilized. The states of CT, NJ, NY, and VA also mobilized resources. The government passed the USA Patriot Act which allowed law enforcement officials to invade the privacy of citizens suspected of terrorism. The National Security Agency also employed listening devices to eavesdrop on the telephone and email communications of people in the USA and other countries without a warrant. In addition, The Homeland Security Act was passed in 2002 to protect the United States from terrorism and natural disasters. Because of the Patriot Act, several of the masterminds of the 9/11 terrorist attacks were captured, like Khalid Sheikh Mohammed (The National Commission on Terrorist Attacks, 2004). After the first attack in New York, the New York Police Department (NYPD), Port Authority Police Department (PAPD), and Emergency Medical Service (EMS) were mobilized to care for the wounded, conduct search and rescue operations. In New York City, the subway was closed and main roadways were cleared for emergency use. In Washington DC, similar actions were taken to secure the city and the surrounding area. In New York, the Fire Department of New York (FDNY) also began search and rescue and firefighting efforts. After the 2nd plane crashed, 2000 NYPD officers rushed to the World Trade Center. In addition, there were numerous port authority officers coordinating efforts with the NYPD and FDNY. In New York City, the Office of Emergency Management (OEM) was located at the WTC. Difficulties occurred in New York because the OEM office was destroyed after the second airplane crash and had to relocate. In addition, many people were trapped in the WTC because rooftop rescues were not possible, and airspace was closed. The authorities and people trapped in the WTC were unprepared for the mass evacuation which occurred. Inadequate communications also created problems in the aftermath of 9/11. Government and local agencies communicated with one another by radio or walkie talkie, as cell phone communications were impossible. Problems occurred with the state and local response in New York because the number of 911 calls disabled the emergency channels. In addition, messages to first responders were given inaccurately which caused problems with search and rescue operations. First responders in New York failed to get relevant radio messages which resulted in the deaths of firefighters and civilians (The National Commission on Terrorist Attacks, 2004). A triage station was established, at the WTC, to treat victims with injuries and transport them to area hospitals. Problems occurred because of lack of communication among the EMS staff and area hospitals. In addition, there was no helicopter transport for the most critically injured patients. Some reports suggested that many of the physicians who became first responders were not adequately trained in emergency medical procedures (Simon Teperman, 2001). In Washington DC, local, regional, state, federal, police, fire, and military agencies responded to the Pentagon attack. In addition, FEMA, the Bureau of Alcohol Tobacco and Firearms, Red Cross, Department of Defense, Ronald Reagan National Airport Fire Department, and the VA Department of Emergency Management assisted. Prior to the Pentagon attack, the government received advanced warning of the hijacking and began evacuating all personnel. Because of the swift evacuation of the Pentagon and skillful mobilization of the state government and local agencies, there were fewer casualties than in New York. Communication in Washington DC was conducted by pagers and walkie talkies, as radio and cell phones did not operate. In the aftermath of the attack, Operation Solace and the Dilorenzo Clinic were established to provide families and victims of the attack with mental health care and therapy. Pentagon workers were desensitized and returned to work as quickly as possible. Operation Solace and the Dilorenzo Clinic were highly successful. People were able to return to work within several days of the attack, and there were no long-term mental health consequences. The Pentagon Family Assistance Center was created to assist people who lost a family member and were homeless because of the attack. Homeless families were housed in the Sheraton hotel for a month and provided with housing assistance. The government also assisted families with financial assistance and memorial services (Ritchie, n. d. ). The 9/11 terrorist attacks were the first large scale attacks in America since Pearl Harbor. The government should be given credit for mobilizing quickly, and speedily establishing services to care for the wounded. Because the government took immediate action, closed airspace and warned the pentagon of the impending attack, lives were saved. Problems with the 9/11 response occurred in the areas of communication and lack of training in some first responders. In future disasters, communication should be conducted by walkie talkie or text message instead of radio and cell phone. Studies have also suggested that first responders need better training to handle large scale emergency events. In the 9/11 disaster, over 3000 people lost their lives. However, because of the courageous actions of the American people and government and local agencies, many people survived the tragedy. The lesson of 9/11 continues to affect American policy on terrorism and disaster planning, at the state and federal level (The National Commission on Terrorist Attacks, 2004).

Fiber Optic History essays

Fiber Optic History essays Our current age of technology is the result of many brilliant inventions and discovers, but it is our ability to transmit information and the media we use to do it, it that is perhaps most responsible for its evolution. Progressing from the copper wire of a century ago to todays fiber optic cable, our increasing ability to transmit more quickly and over longer distances has expanded the boundaries of our technological development in all areas. Toadys low-loss glass fiber optic cables offer almost unlimited bandwidth and unique advantages over all previous developed transmission media. The basic point-to-point fiber optic transmission system consists of three basic elements: the fiber optic cable and the optical receiver and the fiber optic cable. Optical communications date back two centuries to the opical telegraph that French engineer Claude Chappe invented the 1790s. His system was a series of semaphores mounted on towers, where humans operators relay messages from one tower to the other. It beat hand carried messages hands down, but by the mid-19th century was replaced by the electric telegraph, leaving a scattering of Telegraph Hills as it almost visible legacy. In the intervening years a new technology slowly took root that would untimely solve the problem of optical transmission, although it was a long time before it was adapted for communications. It depended on the phenomenon of total internal reflections, which can confine light in material surrounding by other materials with lower refractive index, such as glass in the air. In the mid 1840s, Swiss physicist Daniel Collodon and French physicist Jacques Babinet showed that light could be guided along jet of water for fountain display. British physicist John Tyndall popularized light guiding in a demonstration he first used in 1854, guiding light in a jet of water flowing from a tank. By the turn of the century, inventors realized that bent...

Emigrants vs. Immigrants vs. Migrants

Emigrants vs. Immigrants vs. Migrants Emigrants vs. Immigrants vs. Migrants Emigrants vs. Immigrants vs. Migrants By Mark Nichol What’s the difference between an emigrant and an immigrant, and where do migrants fit in? The answer, for both questions, is that it’s a matter of direction. Emigrant, immigrant, and migrant all stem from the Latin verb migrare, which means â€Å"to move from one direction to another.† The distinction between the nearly identical-sounding first two terms is that emigrant describes a person from the perspective of coming from somewhere else, and immigrant refers to someone in the context of arrival at his or her destination. Simply said, emigrants come from somewhere, and immigrants go to somewhere. (To help you remember which is which, think of emigrants as emerging from and immigrants as being immersed into.) Other terms for this phenomenon that include the root word migrant include in-migrant and out-migrant. Another synonym for emigrant, à ©migrà ©, usually refers specifically to someone forced for political reasons to leave a country; the word is derived from the Latin verb emigrare by way of French. There is no equivalent term synonymous with immigrant, however. A migrant, meanwhile, is a person or an animal who travels to and from two locations, as in the case of an economic migrant who leaves home to earn money in another country and returns periodically before going back to the other country again. (Migrator is an alternative.) Less often, migrant is used to refer to an animal that travels from one region to another depending on the seasons, as when geese in the Northern Hemisphere fly south for the winter as their habitat grows too cold and then return when the weather becomes milder again in the spring. Nouns referring to movement to and from a place, respectively, are immigration and emigration; the verb forms are immigrate and emigrate. Migration describes the process of repeated movement from one place to another and back again (migrancy is a less common variant), and the verb form is migrate; migrant and migratory serve as adjectives, the former usually referring to humans and the latter to animals, and migrational might also modify a noun to refer to back-and-forth movements of humans or animals.
