Plymouth plantation free essay sample

William Bradfords non-fictional work, Of Plymouth Plantation, is a book about the early settlement experiences of the Puritans from 1620 to 1647. Bradford is the governor of the Plymouth Plantation, serving in this role for thirty-three years. He is responsible for the creation and government of the settlement. Bradford begins the work detailing the purpose of the Separatistss emigration, who left England to pursue religious freedom. He also introduces the Puritans, a people who objected to the inclusion of mens inventions. The Puritans split from the Church of England and the Roman Catholic Church because they believed that the latter two were not upholding the true tenets of the Bible and the Christian faith. Their belief caused them to be rejected and persecuted. Persecutions included arrest, torture, imprisonment, and death. In response to this social rejection, the Puritans attempted to flee to Holland, but not without paying a high price.

I, p. 4). In these times, professors were simply those who had professed their beliefs in Christ; it had no relation to any higher education. Bradford quotes Socrates regarding the treatment of those who would not obey the principles of the established church, saying that the treatment of one Christian to another was equal to, if not worse than, the treatment thrust upon Christians in the early days.

The Fascinating History of Drone Warfare

The Fascinating History of Drone Warfare Unmanned aerial vehicles (UAVs) have allowed U.S. military forces to turn the tide in numerous overseas conflicts as well as in the fight against terrorism without risking military personnel. They have a storied past that dates back centuries. While the history of drones is fascinating, not everyone is a fan of these stealthy, unmanned aircraft. While drones are a big hit among hobbyists, providing a wonderful vantage point from which to capture breathtaking aerial video footage, some people are understandably worried about the invasion of privacy as the craft sail over private property. Not only that, as evolving technology becomes increasingly sophisticated, lethal, and accessible to the masses theres a rising concern that drones can and will be used against us by our enemies. Tesla’s Vision Inventor Nikola Telsa was the first to foresee the coming of militarized unmanned vehicles. In fact, they were just one of several predictions he made while speculating on potential uses for a remote control system he was developing. In the 1898 patent â€Å"Method of and Apparatus for Controlling Mechanism of Moving Vessels or Vehicles† (No. 613,809), Telsa described, with remarkable prescience, the wide range of possibilities for his new radio-control technology: The invention which I have described will prove useful in many ways. Vessels or vehicles of any suitable kind may be used, as life, despatch, or pilot boats or the like, or for carrying letters packages, provisions, instruments, objects†¦ but the greatest value of my invention will result from its effect upon warfare and armaments, for by reason of its certain and unlimited destructiveness it will tend to bring about and maintain permanent peace among nations. About three months after filing his patent, Tesla gave the world a glimpse of the possibilities of radio wave technology at the annual Electrical Exhibition held at Madison Square Garden. Before a stunned audience, Tesla demonstrated a control box that transmitted radio signals used to maneuver a toy boat through a pool of water. Outside of a handful of inventors whod already been experimenting with them, few people even knew about the existence of radio waves at the time.   The Miltary Enlists Unmanned Aircraft   Drones have been used in a variety of military capacities: early efforts at eye-in-the-sky reconnaissance, â€Å"aerial torpedoes† during World War II, and as armed aircraft in the war in Afghanistan. Even as far back as Teslas time, his contemporaries in the armed forces were beginning to see how remotely-controlled vehicles might be used to gain certain strategic advantages. For example, during the Spanish-American War of 1898, the U.S. military was able to deploy camera-equipped kites to take some of the first aerial surveillance photographs of enemy fortifications. (An even earlier example of military use of unmanned aircraft- albeit not radio-controlled- took place during an 1849 attack on Venice by Austrian forces using balloons packed with explosives.) Improving the Prototype: Directive Gyroscopes While the idea of unmanned craft showed definite promise for combat applications, it wasn’t until around World War I that military forces began to experiment with ways to further Tesla’s initial vision and attempt to integrate radio-controlled systems into various types of unmanned aircraft. One of the earliest efforts was the 1917 Hewitt-Sperry Automatic Airplane, a costly and elaborate collaboration between the U.S. Navy and inventors Elmer Sperry and Peter Hewitt to develop a radio-controlled airplane that could be used as a pilotless bomber or flying torpedo. Perfecting a gyroscope system that could automatically keep the aircraft stabilized became crucial. The auto-pilot system that Hewitt and Sperry eventually came up with featured a gyroscopic stabilizer, a directive gyroscope, a barometer for altitude control, radio-controlled wing and tail features, and a gearing device to measure the distance flown. Theoretically, these improvements would enable the aircraft to fly a pre-set course to a target where it would then either drop a bomb or simply crash, exploding its payload. The Automatic Airplane designs were encouraging enough that the Navy supplied seven Curtiss N-9 seaplanes to be outfitted with the technology and poured an additional $200,000 into research and development. Ultimately, after several failed launches and wrecked prototypes, the project was scrapped but not before completing one successful flying bomb launch that proved the concept was at least plausible. The Kettering Bug While the Navy teamed up with Hewitt and Sperry, the U.S. Army commissioned another inventor, General Motor’s head of research Charles Kettering, to work on a separate â€Å"aerial torpedo† project. They also tapped Sperry to develop the torpedo’s control and guidance system and even brought in Orville Wright as an aviation consultant. That collaboration resulted in the Kettering Bug, an auto-piloted biplane programmed to carry a bomb directly to a pre-determined target.   The Bug had a range of about 40 miles, flew at a top speed nearing 50 mph, and held a payload of 82 kilograms (180  pounds) of explosives. It was also equipped with a counter programmed to count the total number of engine revolutions necessary for the craft to reach its predetermined target (allowing for variables of wind speed and direction that were figured into the calculation when the counter was set). Once the requisite number of engine revolutions was reached, two things happened: a cam fell into place shutting down the engine and the wing bolts retracted, causing the wings to fall off. This sent the Bug into its final trajectory, where it detonated on impact.   In 1918, the Kettering Bug completed a successful test flight, prompting the Army to place a large order for their production. However, the Kettering Bug suffered a similar fate to the Navys Automatic Airplane and was never used in combat, partly due to concerns that the system might malfunction and detonate a payload prior to reaching its target in hostile territory. While both projects were scrapped for their initial purpose, in retrospect, the Automatic Airplane and Kettering Bug played significant roles in the development of modern-day cruise missiles. From Target Practice to Spy in the Sky The post-World War I period saw the British Royal Navy take the early lead in the development of radio-controlled unmanned aircraft. These British UAVs (target drones) were programmed to mimic the movements of enemy aircraft and were employed during anti-aircraft training for target practice. One drone often employed for this purpose- a radio-controlled version of the de Havilland Tiger Moth airplane known as the DH.82B Queen Bee- is thought to be the source from which the term â€Å"drone† hatched.   The initial headstart the British enjoyed was relatively short-lived. In 1919, Reginald Denny, a serviceman late of the British Royal Flying Corps, emigrated to the United States, where he opened a model plane shop. Dennys enterprise went on to become the Radioplane Company, the first large-scale producer of drones. After having demonstrated a number of prototypes to the U.S. Army, in 1940, Denny got a huge break, procuring a contract for the manufacture of Radioplane OQ-2 drones. By the end of World War II, the company had supplied the Army and Navy with 15,000 drone craft. A Hollywood Sidenote In addition to drones, the Radioplane Company had the distinction of launching the career of one of Hollywoods most legendary starlets. In 1945, Denny’s friend (film star and future President of the United States) Ronald Reagan sent military photographer David Conover to capture snapshots of factory workers assembling Radioplanes for the Army’s weekly magazine. One of the employees he photographed was a young woman named Norma Jean Baker. Baker later quit her assembly job and went on to model for Conover at other photoshoots. Eventually, after changing her name to Marilyn Monroe, her career really took off.   Combat Drones The World War II era also marked the introduction of drones in combat operations. In fact, the conflict between the Allied and Axis powers revitalized the development of aerial torpedoes, which could now be made to be more accurate and destructive. One particularly devastating weapon was Nazi Germany’s V-1 rocket, a.k.a, the Buzz Bomb. This flying bomb, the brainchild of brilliant German rocket engineer Wernher von Braun, was designed to hit urban targets and incur civilian casualties. It was guided by a gyroscopic autopilot system that helped carry a 2,000-pound warhead upward of 150 miles. As the first wartime cruise missile, the Buzz Bomb was responsible for killing 10,000 civilians and injuring around 28,000 more. After World War II, the U.S. military started repurposing target drones for reconnaissance missions. The first unmanned aircraft to undergo such a conversion was the Ryan Firebee I, which in 1951 demonstrated the ability to stay aloft for two hours while reaching an altitude of 60,000 feet. Converting the Ryan Firebee into a reconnaissance platform led to the development of the Model 147 FireFly and Lightning Bug series, both of which were used extensively during the Vietnam War. During the height of the Cold War, the U.S. military turned its focus toward stealthier spy aircraft, a notable example being the Mach 4 Lockheed D-21. Attack of the Armed Drone The notion of armed drones (as opposed to guided missiles) being used for battle purposes didnt really come into play until the 21st century. The most suitable candidate was the Predator RQ-1 manufactured by General Atomics. First tested and put into service in 1994 as a surveillance drone, the Predator RQ-1 was capable of traveling a distance of 400 nautical miles and could remain airborne for 14 hours straight. Its most significant advantage, however, was that it could be controlled from a distance of thousands of miles via satellite link. On October 7, 2001, armed with laser-guided Hellfire missiles, a Predator drone launched the first-ever combat strike by a remotely piloted aircraft in Kandahar, Afghanistan in an effort to neutralize suspected Taliban leader Mullah Mohammed Omar. While the mission failed to take out its intended target, the event marked the dawn of a new era of militarized drones. Since then, unmanned combat aerial vehicles (UCAVs) such as the Predator and General Atomics’ larger and more capable MQ-9 Reaper have completed thousands of missions, sometimes with unintentional consequences. While  2016 statistics released by President Obama revealed that 473 strikes had accounted for between 2,372 and 2,581 combatant deaths since 2009, according to a 2014 report in The Guardian, the civilian death toll resulting from drone strikes was, at the time, in the neighborhood of 6,000.

What are the effects of using ICT and Media in the 'English Classroom' Essay

What are the effects of using ICT and Media in the 'English Classroom' - Essay Example In general, the learning and teaching behaviour between the students and the school teachers, is an important factor that contributes to the success of using computer-based technology in education (Karasavvidis et al., 2003). For this reason, the design of a virtual classroom for English language has to be easily accessible, reliable, user-friendly, and interactive. For this study, the types of ICT and other related media technology used in the English Classroom settings has to be identified first. Eventually, the researcher will conduct a literature review about the positive and negative effects of using the ICT and other forms of media in the English classroom. In the process of going through the main discussion, several issues and problems associated with the use of ICT and other media technology will be identified followed by discussion of the impact of using these technologies on the teaching and learning process of the English language. Based on the gathered peer-reviewed journals, improvements on the students’ academic performance concerning the use of each type of media technology will be tackled in detail. With regards to the school improvements, some of the existing teaching and learning theories will be applied to the practice of using ICT and other forms of media technology. Under the supervision of the British Educational Communications and Technology Agency (BECTa), UK government is strongly committed in supporting the use of ICT within the classroom settings (Becta, 2009). Similar to the personal opinions of the secondary school teachers (Clarke, 2003: p. 3), the UK government also finds the promotion of using ICT as one of the best way to improve and strengthen the learning experience of the students. As a result of the rapid development in the use of ICT and media technology, educational settings like the English classroom has been using digital technology in order to support the learning

FGF Signaling and Early Lung Development Essay -- Biology, Lung

Epithelial-mesenchymal interactions mediate organogenesis, which results from the activation of complex gene networks. Early respiratory development arises from the foregut endoderm and gives rise to tracheal and lung progenitor cells. Recent studies have linked fibroblast growth factor, Wnt, and other signaling pathways to the initial stages of lung development. Cells respond to signaling proteins mainly though transcription factors that ultimately determine cell fate and pattern formation. Gain and loss-of-function studies have facilitated the identification and functionality of molecular components as part of development. Fibroblast growth factor (FGF) signaling plays an important role in the regulatory network present in embryonic pulmonary development. FGF controls cell proliferation, differentiation and pattern formation; however, the interaction of FGF with other signaling pathways is still questioned by researchers. FGF-7 and FGF-10 are important for patterning and growth of the lung bud and are differentially regulated by FGF-1 and FGF-2. Research has shown FGF is an important factor in respiratory development as it regulates the expression of other signaling pathways. Said molecular events involving FGF signaling drive key phases of pulmonary development and thus the understanding of these key segmental mechanisms gives way to new knowledge of pathogenesis involving congenital anomalies, helping to develop innovative therapies to treat disease. Unless specifically mentioned, anything regarding expression patterns and developmental effects of morphogens, transcription and growth factors, or any other developmental factors effecting lung development are referenced from the murine lung. Accordingly, functional relevance... ...change, an extremely complicated process. The lung is an organ that contains a vast system of airways carefully constructed to achieve maximal surface area in a confined space. This helps to form an environment suitable for the bronchial and pulmonary vascular systems. These airways that grow out into the body, like a tree towards the sky, require careful guidance from many developmental factors such as transcriptional regulators, growth factors, morphogens and extra cellular matrix molecules. When mutations in the genes that control these factors occur, aberrations during lung development can arise and may lead to severe morbidity or mortality at birth due to respiratory failure. The FGF signaling pathway is one such signaling mechanism that is critical to proper lung formation, guiding branching morphogenesis and cellular proliferation of the developing lung.

Assessment Sheet Essay

Sheet What are three key things you learned about the Dark Ages in this lesson? Please be sure to include at least two complete sentences for each one. In Norman settlements, Lords controlled the villages as well as ruling and governing their land. Lords were oftentimes knights and served the king Norman settlements were surrounded by a wall that encompassed the lord’s house, and the rest of the village and the lord’s house usually had yet another wall. The village usually contained a stockpile of food, a well, and weapons. The idea is that they would have everything that they needed to survive within the walls, in case of an attack. Old English resembles modern English, but not very closely. One must remember that old English was only a component of the languages that formed together to make modern English. Latin, Celtic and German were blended together and reformed over time to make today’s English. Christianity wasn’t always the main religion of ancient Britain. It only became truly popular and dominant after the romans had been ran out of Britain and the Germanic tribes formed together to make the Anglo-Saxons. Explain two things that you would still like to know about the development of Old English. Please be sure to include at least one complete sentence for each one. I would like to learn more about the Modern English words that show roots in German Latin and Celtic. I would enjoy studying which language our grammar is based off of, and how we mixed certain rules in grammar from different languages. In one paragraph, describe how the language of English evolved during the Dark Ages. What were the influences that changed it over the years? Which ethnic backgrounds were involved in this evolution? Please write at least four sentences for this response. Old English gets its roots from the Celtic language that was spoken in ancient England. The romans invaded, and sent the Celtic population north and into Ireland. The clashes with the romans brought a little Latin into the language. When the Germanic tribes invaded the language also adopted a little German and the mix was known as Old English.
