Academic performance and technology Essay Example for Free

Academic performance and technology Essay Space exploration is the discovery and exploration of outer space by means of space technology. Physical exploration of space is conducted both by human spaceflights and by robotic spacecraft. While the observation of objects in space, known as astronomy, predates reliable recorded history, it was the development of large and relatively efficient rockets during the early 20th century that allowed physical space exploration to become a reality. Common rationales for exploring space include advancing scientific research, uniting different nations, ensuring the future survival of humanity and developing military and strategic advantages against other countries. Space exploration has often been used as a proxy competition for geopolitical rivalries such as the Cold War. The early era of space exploration was driven by a Space Race between the Soviet Union and the United States, the launch of the first man-made object to orbit the Earth, the USSRs Sputnik 1, on 4 October 1957, and the first Moon landing by the American Apollo 11 craft on 20 July 1969 are often taken as the boundaries for this initial period.

After the first 20 years of exploration, focus shifted from one-off flights to renewable hardware, such as the Space Shuttle program, and from competition to cooperation as with the International Space Station (ISS). With the substantial completion of the ISS following STS-133 in March 2011, plans for space exploration by the USA remain in flux. Constellation, a Bush Administration program for a return to the Moon by 2020 was judged inadequately funded and unrealistic by an expert review panel reporting in 2009. The Obama Administration proposed a revision of Constellation in 2010 to focus on the development of the capability for crewed missions beyond low earth orbit (LEO), envisioning extending the operation of the ISS beyond 2020, transferring the development of launch vehicles for human crews from NASA to the private sector, and developing technology to enable missions to beyond LEO, such as Earth/Moon L1, the Moon, Earth/Sun L2, near-earth asteroids, and Phobos or Mars orbit.[5] As of March 2011, the US Senate and House of Representatives are still working towards a compromise NASA funding bill, which will probably terminate Constellation and fund development of a heavy lift launch vehicle (HLLV).[6] In the 2000s, the Peoples Republic of China initiated a successful manned spaceflight program, while the European Union, Japan, and India have also planned future manned space missions. China, Russia, Japan, and India have advocated manned missions to the Moon during the 21st century, while the European Union has advocated manned missions to both the Moon and Mars during the 21st century. From the 1990s onwards, private interests began promoting space tourism and then private space exploration of the Moon (see Google Lunar X Prize). Benefits of this to Mankind There are critics who disagree with the expenditure on space exploration, which they claim can better be used to solve earthly problems. However, they seem to forget that this is one of the fields which tests a mans intellect. But, how does a common man draw benefits of space exploration? The advances made in field of space exploration can be well used in other fields such as medicine, agriculture, etc. The following is the list of benefits of space exploration to mankind: Global Positioning System: The mankind depends on the sea trade for transportation of food grains, fossil fuels, metal ores, etc. Global navigation system, GPS helps in timely delivery of these essential goods by providing the ships with essential navigation information. The GNS services are made available using networks of satellites which also enables satellite Internet and satellite phones. Weather Forecast and Agriculture: Gone are the days, when we used to take an umbrella with us while going out if there were black clouds in the sky. Now we can rely on the weather reports updated on an hourly basis. The accurate weather forecast is possible only because of the satellites in the space. The satellites also help us in predicting the crop yields, pest infestation and the area under cultivation. Natural Calamities: It is easy to predict natural calamities such as floods, storms, tornadoes, hurricanes and to locate wildfires and their extent with the help of satellites. Minerals and Mining: Minerals buried deep under the Earths surface can be located using satellites. Precious fossil fuels can be found with the help of satellites. Electronics: The field of electronics and computers have also benefited from the space exploration. The astronauts have manufactured miniature electronic parts that could only be produced in the space during their experiments in the space stations and space shuttles. Asteroids: It is believed that an asteroid strike eliminated the dinosaurs on the Earth. One of the benefits of space exploration is that we know about the thousands of asteroids and we can also be vigilant about their drifts. May be we could prevent dinosaurian death of mankind, if and when an asteroid is positioned to repeat history. If it happens, it would be because of the knowledge which is the direct benefit of space exploration. Energy Source: The scientists and researchers all over the world are attempting to harness the power of nuclear fusion. The process which enables the Sun to produce energy in abundance. It is believed that quantity of electricity generated using 1kg of hydrogen would be equivalent to that of 11,000 metric tons of coal. Medicine: Another field to glean the benefits of the satellite exploration is that of medicine. Metal alloys that are manufactured to be used in spacecraft and space shuttles are also used in the health care industry. Nitinol, an alloy is used to make braces. The miniature electronic components which were developed for the space program can be used in electronic pain-control device that some patients need to use. The implantable insulin pump is based on the mechanical robot arm developed for the Mars Voyager probe. The space exploration benefits also encompasses the field of communication which needs no explanation. The applications of knowledge and the technologies, that are the outcome of the mans efforts to explore space, are making his life easier indeed!

Brazilian Educational System Essay -- Education, Faith Schools

Whereas, there are few researches related to the impact of non-Christian students in Christian institutions, this study was designed to present the perceptions of insiders to the Brazilian educational system instead of the usual outside perspective. Therefore, were chosen as subject Adventist schools in the North of Brazil due to their expressive number of non-Adventist students enrolled there. The aim of this basic qualitative study is to investigate the characteristics of these schools in particular from denominational and educational leaders’ perceptions about the elevated number of non-believer there. Naturally, methods of data collection used in this study were semi-structured interviews, focus group interviews, and statistical documents from the funding institution. The research questions arising from the above objective were as follows: 1. What are the reasons for enrollment of the non-Adventist students in Adventist schools? 2. What dangers and/or advantages for Adventist schools with high number of students who do not profess the same values and beliefs? 3. What kind of actions can be taken to solve or soften this trend? REVIEW OF THE LITERATURE The expansion on the number of enrollees from other religious denominations or beliefs is a phenomenon perceived by faith schools. Although the debate between the evangelistic and protective social function of the crest schools yet persist in some academic circles, in many places around the world economic, legal, and cultural factors have impact. Tevni, Grajales, & Leon (2010) conducted a study in SDA schools with students and parents from diverse religious beliefs in Chile. They found out that both SDA and Evangelical parents contribute on ratings of emphasis on educati... ...o make distinction in the admission of students based upon race, gender, nationality, religion, or ethnic origin, students from different backgrounds have been enrolled in Adventist schools. Based on statistic report of Education Department of North Brazilian Union, the Low Amazon Conference's schools have presented an increase in number of students in all decades except in 1990s to 2000s where were lost of 1953 students in elementary-level. It happened due to economic crisis from 1996 to 2003 that led to the closure of several small schools (Azevedo, 2005). In 2010, were enrolled 6.715 students from pre-school to high school in eight elementary and two secondary schools where 77% of students belonging to other faiths and ideologies. For this study was included the secondary classes of the recent inaugurated Adventist Amazon College, located in Benevides, Parà ¡.

A Jury of Her Peers – 1

An Analysis of Characterization in â€Å"A Jury of Her Peers† In â€Å"A Jury of Her Peers† written by Susan Glaspell and published in 1917 a man named John Wright was choked to death in his bed with a rope. John Wright’s wife, Minnie is the prime suspect and has been taken to the jail to await her trial. The county lawyer George Henderson, the sheriff Henry Peters, his wife and the local farmer Lewis Hale and his wife Martha arrive at the home of John and Minnie Wright trying to locate clues so they could hold a trial and convict Minnie for the murder of her husband. Mrs.Peters and Martha Hale, both very observant, quickly take note of the obvious clues in the home but choose to not reveal them to the men. This story takes place during a time when women were made to feel inferior to men. This is ironic because the men fail to see the obvious clues, that the ladies are uncovering, that are important to their investigation. Minnie Foster Wright, who is the main ch aracter in the story, has been forced to change her identity from a lovely girl who loved to sing in the choir and wear pretty dresses to one of a subservient housewife.Minnie is a very dynamic character whose dreams were represented by her pet canary and ultimately choked by the hands of her husband. The story gives a lot of insight into the life of Minnie Wright and how she felt as a housewife but it is done through the eyes of her peers. George Henderson comes across as being narrow-minded and egotistical. He talks down to the women throughout the entire story, he looks inside the cupboard and says, â€Å"Here’s a fine mess† (Glaspell 540).After multiple comments and derogatory looks toward the ladies the lawyer remembers his role in the community and states, â€Å"for all their worries, what would we do without the ladies† (Glaspell 540)? George Henderson then falls back into superiority by criticizing the disarray and dirt in the farmhouse. Lewis Hale and H enry Peters share the same opinion of women and do not mind letting their wives know their place in the home. Mr. Hale made a statement that the women wouldn’t know a clue if they came upon one and that they were only used to worrying over trifles. Ironically Mr.Hale never realized that while he was busy keeping the women in their place they were solving the murder. Mr. Hale and Mr. Peters are so detached from the domestic world they didn’t view the kitchen and its condition the same way the women did. Mrs. Peters and Mrs. Hale were under no illusions as to why the kitchen was in such disarray. The story indicates that Mrs. Hale is an obedient housewife that is very comfortable in her role being married to a farmer. She is a strong lady, a woman of principle and a lady that is given to neatness and that leaves no job unfinished.For example, Paragraph 1 states â€Å"her bread all ready for mixing, half the flour sifted and half unsifted†. This may seem to hold li ttle significance to the story however we find that Mrs. Hales neatness and sense of organization allows to her see clues that the men overlook because of their views of the home. Mrs. Peters on the other hand seems to be very uncomfortable in her role as the sheriff’s wife. Initially in the story Mrs. Peters appears weak and unwilling to withhold the clues from the men investigating the crime. Mrs.Peters also discourages Mrs. Hale from withholding clues and tampering with evidence, however as the story progresses we find that Mrs. Peters has very strong convictions and that she can and will rise to the occasion. The ladies quickly pieced together what had happened, however because they relate to Minnie they chose to keep it between themselves. To these ladies dirty towels and dishes were signs that things were not well at home. Mrs. Peters knew Minnie as a young lady that was full of life, had a beautiful voice and wore pretty clothes.Over time things changed for the ladies and they grew apart and the guilt that was felt for not being a better neighbor and friend weighed heavy on their minds. Mrs. Peters said, â€Å"I know what stillness is† (Glaspell 550). Mrs. Peters understood where Minnie had been in life because her life wasn’t that different. Although the ladies knew Minnie had committed the crime it wasn’t until they found the broken cage and the choked canary that they felt empathy for her and begin defending her actions.They both understood that John Wright had taken her song, â€Å"She used to sing. He killed that too† (Glaspell 550). The ladies knew that the crime should be punished but they justified the crime in their minds based on their personal situations, the way John Wright had treated Minnie, and the fact they hadn’t taken the time from their own lives to visit. The ladies seemed to secretly enjoy knowing they have solved the puzzle based on their domestic skills of working in the kitchen down to th e type of stitching on the quilts, even if that meant Mrs.Peters going against her husband who was the law. They continued to talk in domesticated code to the men to the very end of the story where Mrs. Hale gave the men the final clue by using quilting terms and stating, â€Å"We call it knot it, Mr. Henderson† (Glaspell 553).

Effects of Global Warming - 535 Words

If you look at our planet in the 1950s you would see that the continents Europe and North America would be 4 feet closer together. There would also be 2/3 less humans as there is now on Earth., earth, twice as many trees covering the land and, three times as muck drinking water available to us. Another reason of future human extinction is coming is the rapid climate change. The rapid climate change is causing the Arctic ice cap to melt at a fast pace. The human race would become extinct by over population, more devastating natural disasters, along with continents converging together. Global warming is causing more powerful hurricanes and even more intense. Warmer ocean water makes the wind speed of a hurricane more power full and more destructive. Hurricanes get their strength from water that has been heated to at least 80 degrees Fahrenheit. The global temperature is rising so that makes the water warmer in turn that makes the hurricanes more intense and higher wind speed. Typical ly about 85 tropical storms form on earth each year but only half of them go on to become a full hurricane. Only nine hurricanes on average form annually in the Atlantic ocean.
