Research and Practice Assignment Example | Topics and Well Written Essays - 250 words

Research and Practice - Assignment Example From the above explanations, it is clear that research and practice revolves around adult learning. The basics adult learning and research rely on four major areas, which include experiential learning, self-directed learning, learning to learn, and critical reflection (Brookfield, 1995). On a personal point of view, reflective teaching and action research will greatly improve personal skills in teaching. This will in turn improve development students through effective teaching in class leading improved overall performance for both the teacher and the students. Teacher research will unite the practical and theory that is mostly associated with the practice of teaching. Action research involves five major steps, which as a practicing teacher prove to be very helpful. These steps involve planning, then taking into action, carrying out observation, reflecting on the outcome and finally re-planning on a more effective strategy (Kemmis & McTaggart, 1990). It is common for teachers involved in carrying out action research frequently raise their issues and observations reflecting their teaching and their students’ progress. Research therefore enables teachers and educators have an overview of problems and issues affecting their collective areas of interest. Action research therefore, helps teachers be in tune with their students prompting for improved classroom engagement between teacher and

Screening Asia ( commenting asian movie ) Essay

Screening Asia ( commenting asian movie ) - Essay Example China produces movies with a collective bent while Taiwan produces individualistic movies. Additionally, the movies produced by China have a big scope, but are not as outward as those produced by Taiwan. 2. What is a Brief History of Taiwanese Nationalism and Film? Taiwanese Nationalism is an important aspect, as the Taiwanese nationalism has been highly diverse. This is because different colonialists colonized Taiwan. Before democratization, the Kuomintang considered Taiwan to be part of China that would be joined with the mainland. Therefore, the expression of Taiwanese nationalism was highly discouraged. The colonizers in Taiwan allowed the production of movies; however, they put great restrictions on it. Only movies in Mandarin Chinese languages were allowed. Additionally, the Kuomintang produced movies that portrayed the behavior of an ideal citizen. Overall, early film in Taiwan was a way communicating political ideas. However, after democratization, Taiwanese films started to address historical and cultural issues, thus ushering in the â€Å"new cinema.† Here most movies addressed important aspects such as Taiwanese identity and Taiwanese political history. 3. What is your favorite time of the Taiwan film? Why? My favorite time of the Taiwan film is the â€Å"New Cinema.† This was a period when the Taiwanese had the freedom of developing their films without any influence from colonizers. Initially, the different colonizers of Taiwan were restrictive to movie production in Taiwan. Nonetheless, with the â€Å"new cinema† period, the Taiwanese got back their right of expression, thus produced movies that explored various topics in society. 4. Do you think that Taiwanese films are being heavily influenced by foreign culture? I feel that Taiwanese films are not being influenced by foreign cultures. In the past, foreign cultures influenced Taiwan movies, but this is not the case today. This was the case in the past, as Taiwan was colonized by different foreign countries, which imposed their cultures on Taiwan, including Taiwan’s film production. 5. Why do you guys think the Taiwan’s cinema producer  have to include Japanese girl character on the movie? Why not leave alone the Taiwan character? any opinion? The Taiwan film producers feature a Japanese girl character on the movie, probably because Japan as a country had a great influence on Taiwan. Including Taiwan’s film. Japan colonized Taiwan for a long time, beginning 1895 to1945. During this time, Japan had imposed its culture on the Taiwanese, who were naturalized to become Japanese. These therefore, were expected to dress like Japanese, eat Japanese food, speak Japan, engage in Japanese religious rites, and use Japanese names, among others. Therefore, maybe this great influence of the Japanese culture on the Taiwanese culture had a great impact. The Japanese also had an influence on Taiwanese film production, as these produced documentarie s and feature films that were mainly political in nature. Therefore, I consider that the influence of Japan on Taiwan is still felt through the Taiwanese films today. Korea 1. How was your first impression on Korean films?  Have you been consider that Korean public films are ‘too commercial’, or inartistic?  If so, what is the rationale behind your notion? I consider Korean films to be of low quality, as compared to those produced in the USA. This is

The Significance of Bacteria in the Ecology Research Paper

The Significance of Bacteria in the Ecology - Research Paper Example The cell membrane is composed of lipids (phospholipids ) such as cholesterol, proteins, and lipids or protein carbohydrates associations.The function of the cell membrane is to regulate the materials which enter and leaves the cell. In evolution, bacteria have produced nutrition for communities of living organisms through photosynthesis and chemosynthesis. Other significances both ecological and evolutionary includes: they are decomposers of ecosystems (they decay dead organisms to release elements needed by other living organisms), the metabolic processes of some bacteria produced the first oxygen gas in the atmosphere, they aid in atmospheric nitrogen fixation and also as ecological decomposers by cleaning environment and releasing elements needed by other organisms from dead decaying matter. In symbiosis, parasites obtain nutrients and nourishment and harm their hosts, while they get nourishment and nutrients and neither do they harm nor benefit their hosts. On the other hand, mutualists benefit their hosts. Sexual reproduction is advantageous in that it results in variation e.g offsprings of human can have traits from all the four grand parents. Asexual reproduction, on the other hand, is advantageous because it results in the in production of great numbers of offsprings hence high survival chances of a given species. In mitosis process, one nucleus divides into two identical nuclei while meiosis is the process by which one nucleus with two copies of each chromosome divides into four nuclei with one copy of each chromosome.

Chemistry Experiments - Lab Report Example This methodology is widely use to determine concentration of various metal ion like Cu, Al, sulphide etc. being highly sensitive and accurate methods precautions should be taken while performing estimations. some of them are as follows. Copper iodide forms week complex with molecular iodine (I2), which slowly leach out and gives re-coloration to the solution after discoloration. Avoid that potassium thiocynate can be added to the system. Proper observation of discoloration must be taken and any modification in it leads to differential endpoint and hence final result. White bright tiles or any white paper can be kept below flask to distinguish different coloration and end point. There is slight difference in obtained results and actual values as there are chances (Mary Ann Varanka-Martin) (WKU website) (MHS Chemistry ) of error and limitation of procedure leads this difference. Both experiments gives Idea of water contain in hydrated Cuso4 crystal and make us understand how water plays important role in crystallization. Slight modification in above mention experiments give us more information about thermodynamics of crystallization and how different lows of physics and chemistry applies to crystallization process For example if we estimate the water evaporated during heating by obtaining condensate of it, gives clear cut idea of law of mass conservation and also validate results by one more means. Similarly estimation of heat generated during rehydration of CuSo4 gives idea of law of energy conservation and make us understand how energy get disappears in form of

SWOT Case Study Example | Topics and Well Written Essays - 750 words

SWOT - Case Study Example The Dim lighting company is faced with several problems that include macro and micro challenges, the macro challenges are those that are outside the reach of the company to solve them using internal mechanisms, in other words, they are the opportunities and threats that the company faces. One of the greatest threat that the company faces is the lack of adequate funds to support its research and development kitty which Mr Spinks, the director of research and development at the company puts at 1.2 million dollars per year for two years then an additional 500, 000 dollars to initiate production the micro miniaturization project (Brown, 2011, p81). Another threat that is facing the company is the decline in the profit margin for the last one year, which has an implication on the image of the business to the outsiders. The company however, is not without some opportunities, the major opportunity that the company has is that it acts as a profit centre therefore it is able to manage its resources with minimal interference from the corporate head office, in addition, this enables it to make its own decisions and implement them in order to remain competitive in the market. In addition, the fact that the company can be able to look for funds from the head office to invest in research and development is an opportunity that may not be available to all such firms. Internally, the strength of the company is that it has Mr Spinks as the director of research and development; Mr Spinks is a respected person in research as he is considered as one of the best brains in research, this can be seen in the numerous awards that he has received from different science societies . With Mr Spinks as a director, Dim lighting company is likely to be always ahead of other companies in terms of technology and renovation; this is evident from the multimillion-research project that he wants to undertake on micro miniaturization

Economical and Environmental Cost-Benefit Analysis on Hybrid Cars Essay Example for Free

Economical and Environmental Cost-Benefit Analysis on Hybrid Cars Essay A hybrid car is a car propelled by the application of two or more power sources. First attempts to introduce hybrid cars goes back to mid 1660, way before the discovery and introduction of the fuel powered conventional cars but were never commercially manufactured until 21st century when Japanese car manufacturer, Toyota produced the Toyota prius exclusively for its domestic market. In fact, it is estimated that the first attempt to produce a hybrid car was in 1665. The delay in the production of this class of vehicles was because of two main reasons; first, the limited range in the distance the vehicles could cover and secondly the difficulty and costly process of recharging their batteries. Furthermore, it is a basic science concept that the more complex a machine is the more it is prone to failure and thus the idea of commercial production of hybrid vehicles has been a slow process over the centuries. World’s population explosion, demand for fresh air and green cities, dwindling petroleum deposits, over dependency in overseas oil, economic recession and global warming are just some of the environmental and economic factors that have forced world’s leading car manufacturers to provide to the market car models that are not only environmentally friendly but also cost effective. A cost-benefit analysis on this topic will attempt to bring out the cost of getting a hybrid car into the road in comparison to the benefits that the world stands to reap as a result of this venture. This research seeks to bring to the surface three major aspects that are associated with the introduction of hybrid cars into the transportation world. These three issues are: (i) The cost of producing a hybrid car: The successful landing of a hybrid car is in focus under this area. It is not easy to get into the road a car that makes use of a combination of two or more sources of energy. The research involved is estimated to run to millions of dollars thus sky-rocketing the price of a hybrid car. (ii) Environmental factors: Environmental factors simply refer to the concerns that a particular type of car produces substances that injure our surroundings thus making life on earth more dangerous and therefore more complex. These substances include green house gases as well as toxic metal compounds such as the ones that contain lead in their structure. (iii) Economic cost benefit factors: Economic factors have much to do with the living standards of people as far as the generation and investment of money is concerned. The economic make up of the world has gotten pegged heavily on oil and there are concerns from every right thinking citizen of the world that this is a self consuming trend that is likely to create serious economic problems if the oil industry hits a serious problem. This has already been witnessed before whereby a slight rise in oil prices has sent shockwaves in economies in both the developed and the developing world. Literature Review The former Vice President of the United States who later won the Democratic Party nomination and lost the presidency in a controversial manner to George W Bush, Mr. Al Gore, has had the world rethinking its actions as far as the degeneration of the environment is concerned. An inconvenient Truth, a film he worked on captures the problems that are already being experienced in various parts of the world as a result of global warming. This, he says is being fuelled by the use of environmentally unfriendly cars that use oil or gasoline (Gore, 2006, para1-3). It is not surprising that he went a head to win a Nobel Prize for this peace of work. Electric and hybrid cars have always received much appreciation due to the perceived ability to tackle this burning issue of climate change. Their ability to cut the emission of these toxic substances into the atmosphere that lead to negative climatic shift is the major reason for this (Anderson and Anderson, 2004, pp 6-10). In recognition of this serious problem, vital steps have been made in the research that is involved in the development and production of cars that make use of a combination of two or three sources of locomotive energy. Chief among these is the research into electric cars that promise to reduce the overreliance on oil (Westbrook, 2001, pp 34-39). The pioneer nation in the world in the research and possible mass production of hybrid cars is Japan. But the appetite with which the United States of America has picked up the issue points to the significance of this type of car. The driving force is the reduction in pollution, the saving that comes in terms of finances and most importantly national security that is put at risk with too much dependency on foreign oil. The argument is often projected in terms of supplying their dollars to nations that fund terror groups such as al Qaeda (Boschert, 2006 pp 2-7). It is common knowledge that mass production of hybrid cars will not only provide a partial solution to world environmental problems but also be a practical measure to save countries from losses running to millions of dollars due to escalating prices of world crude oil. The cost of producing a hybrid car The production of hybrid cars is not a cheap or a simple venture. Confessions by companies that have dipped their fingers into this hot pot have clearly shown that more than just simple technology is in play in the production of this type of cars. Research that has been on-going for a long time now is very complicated and has consumed millions of dollars. At the end of the day, despite the hyped advantages of shifting from purely oil consuming cars to hybrid cars, the cost that must be borne has to be high (Westbrook,2001,pp 56-61). It is the overall ability of the hybrid car to assist man in solving most of his economic and environmental problems that make the whole exercise worthwhile. Environmental factors While scientists agree that there can never be perfect environmentally friendly hybrid cars and that this depends solely on the design and model of hybrid power system. It is worthy appreciating that the use of this class of vehicles will automatically lead to the reduction of global warming by approximately 0. 3 to 0. 5 percent and that more advanced models and designs in the coming years due to technological advances would reduce this figure even further. The problems of the quality of urban air, reduction of noise due to application of electric motor in fuel power conventional cars, and elimination of smog forming pollutants could be solved in a century if research on mass production of hybrid cars is given a priority. The main source of air pollutants in cities and major towns is transportation. Fuel powered conventional motor vehicles produce much higher levels of carbon dioxide (Co2) carbon monoxide (Co), nitrogen oxides (Nox) and hydrocarbons (Hc) and this from the primary source of these dangerous pollutants. This is mainly because fuel powered conventional cars (FPCC) make short trips that do not give time for electric motor warm ups and cold starts. It is noted that hybrid cars reduced the levels of the carbon monoxide, hydrocarbons and carbon dioxide by 97% in comparison to other sources of these pollutants. Carbon monoxide (C0), when inhaled for long periods interferes with the proper functioning of the brain in that it impairs the flow of oxygen (O2) into the brain. Once the brain stops working in the expected way, the person involved turns into a vegetable. Carbon dioxide and water vapor form the principal components of green house gases that bring about the green house effect. Green house effect is a scenario in which too much heat is trapped within the atmosphere due to the presence of such toxic gases as carbon monoxide and this resultant effect is a highly raised earth temperature. Infact carbon dioxide (C02) is considered one of the major atmospheric pollutants, and is solely responsible for approximately 57% global warming. Negative effects of global warming include the rapidly declining numbers of polar bears and melting of ice in the tropics. It is therefore an open knowledge that releasing carbon dioxide (C02) into the atmosphere is detrimental to the lives of living organisms and the equilibrium of the ecosystem. Sulphur and chlorofluorocarbons (CFCs) are very dangerous air pollutants produced by combustion of sulphur containing fuels. Over the years, scientists have devised means of producing sulphur and lead free fuels but achieving an excellent degree is still a distant mirage. Deposition of these compounds in the air is harmful to plants, man and infrastructure. Exposure to high concentration of sulphur dioxide irritates respiratory tracts making breathing difficult and can easily cause lung problems. Sulfur Oxide contributes to respiratory illness. Patients suffering from heart diseases risk aggravating their conditions if exposed to even mild concentration of sulfur oxides. These components also form secondary pollutants when transported and combined with other elements forming sulphates, nitrate salts, nitrogen dioxides and even nitric acid vapor. This is what is commonly known as acid rain that corrodes buildings, burns vegetations, burns the human skin and destroys infrastructure. Chlorofluorocarbons also form component of green house gases that bring about the effect of global warming. When exposed to gamma rays, these compounds break down to release chlorine atoms. The presence of chlorine atoms in the atmosphere catalyses splitting of Ozone (O3) into oxygen gas (O2), however the negative effects of their presence overweigh their importance. Photochemical air pollution, usually known as smog and is commonly sported in the tropics and subtropics is also caused by incomplete combustion of gasoline emitted by fuel powered conventional vehicles. This process leads to the production of Ozone gas that is responsible for irritation in the eyes, extensive damage to plants and crops and lung complications. The release of carbon dioxide (C02), chlorofluorocarbons (CFC), sulphur oxides, nitrogen oxides (N0x) and other pollutants into the atmosphere contributes to the destruction of plants on the earth’s surface. Photosynthesis, the process through which trees produce oxygen from carbon dioxide is so vital to human life in fact it is said that life cannot exist without trees. Destruction of trees by releasing these pollutants into the air is equal to destruction of both human life and plant life. While particulate matters are the main contributors to lung problems and most cancer cases, hydrocarbons are also a cause of lung problems and other tissue problems. Long exposure to high concentrations of hydrocarbons eventually leads to total organ failures. Furthermore it is a major contributor to birth defects and other complicated illnesses like cancer. With the commercial manufacture and introduction of hybrid cars, extensive damage to the environment is definitely reduced, quality of life enhanced and urban areas become clean to inhabit, the dream of world environmental rights groups. Economic factors Crude oil is the raw material that propels almost all components of world’s economy in many ways. In fact the world is so dependent on crude oil that if its supply would be cut abruptly, major world economies like United States of America, Russia and China would immediately come to a standstill. United States depends on crude oil alone for 40% of its energy supply, triple than other sources. Overdependence on crude oil is not sound enough. First, crude oil is a non-renewable source of energy and analysts predict it will be largely exhausted within half a century. This rings an alarm bell that if measures are not put in place and countries go green by using hybrid cars, then the future is bleak and the word is in danger. Transportation sector depends entirely on oil for energy supply. Trucks, planes, ships cars and buses are propelled by motor engines that use oil. Introducing hybrid cars would reverse this trend, make the world safer from fluctuating oil prices and reduce dependence on this energy source (Paterson, 2007 para. 3-5). Reliance on crude oil for fuel supply is a major contributor to ethnic and tribal wars in Africa. This demonstrates the levels at which scramble for this commodity has reached. In fact notably China is so hungry for crude oil that it is ready to ignore the sufferings of millions of peoples around the world and specifically Sudan, so as to get its industry moving. It therefore points to the fact that lasting peace and safety will be found and armed conflicts reduced drastically when less fuel consuming cars are produced and thirst for oil curtailed. Hybrid cars are pocket friendly as they consume less gasoline in comparison to fuel powered conventional cars. Even though they are slightly expensive to purchase, the reward is achieved in long term due to lower fuel consumption. Further, governments and notably the United States of America give tax incentives to buyers of hybrid cars in to a move aimed at reducing the average prices of these vehicles and thus encouraging more people to purchase them. Dwindling petroleum deposits in a major concern to the world. It is widely acknowledged that only a total of one trillion barrels of recoverable crude oil reserves is available for exploration worldwide with only two percent (2%) of this value in the United States of America. Most of these oil deposits are found in the eastern hemisphere that is made up of countries that are well known for political instability. It is therefore very wise for countries that fall in the Western hemisphere and more so, the United States to adapt the mass production and commercial use of hybrid vehicles. This will not only cushion them from ever fluctuating oil prices but will also prevent the imminent collapse of most sectors of the economies of these countries. Conclusion From the foregoing, it is evident that the world stands to gain immensely from the introduction into the world of transportation hybrid cars. It is true that the cost of producing a hybrid car is not one that sends one smiling all the way to the bank. In fact it is prohibitively high and the faint hearted who will not pay attention to the long term benefits of this hybrid car model will not dare. But the benefits or gains both in terms of saving a planet in peril and a global economy in a shambles are so enticing and crucial that it is actually the way to go. The environmental problems that come as a result of oil utilization in transport and other areas of life will be dealt with once and for all. For instance, the release of dangerous gases such as carbon dioxide and carbon monoxide into the atmosphere that is responsible for global warming and numerous respiratory problems as well as problems in farming thorough such phenomena as acid rain will be solved. The economic woes that emanate from over dependence on oil will also be contained. The availing of financial resources to rogue nations such as Iran that fund terrorist groups, the shaking of the global economy due to shifts in oil prices as well as the escalation of conflicts in most third world countries in the east and Africa as a result of scrambling over oil resources will be eliminated.

The Challenger Address Essay Example for Free

The Challenger Address Essay Ronald Wilson Reagan was the 40th United States President after winning against the Democratic Challenger Jimmy Carter in the 1980 presidential election. Reagan won by attaining 50. 7% of the popular votes in that particular election. It can be said that the beginning of his term was not that pleasing. On his first year of term, he fired 11,345 air traffic controllers who, according to him violated the regulation of the government that prohibits unions from striking. Also, it had been said that unemployment in the United States increases to 10. 8%, which is greater than any time since the great depression during his first year in position. However, this percentage dropped during the rest of his presidency. It can also be said that after his first term, Reagan gained the respect and trust of the American people by being nominated for the second time as the president of the United States on the 1985 presidential election in which he was elected by landslide, having unprecedented number of votes. It was also said that during his years of presidency, restoration of prosperity was viewed by the people as well as global peace. It was also in the year 1986 that the income tax code was revised by Reagan wherein millions of people with low income were exempted. The year 1986 is not just a year of development in terms of social conditions in the United States; it was also a time wherein space exploration was greatly admired. By that time there had been several developments and expeditions that can be considered successful. Thus, the people especially Americans were very enthusiast to explore and to achieve greater heights in terms of space travel and exploration. However, this year was also a tragic time for the space exploration era when the Space Shuttle Challenger explodes a short while after lifting off, leaving none of the seven crews alive on January 28, 1986. The public was shocked at what they witnessed. Also, by that time, President Reagan was planning to deliver a speech to the American people but was compelled by the tragedy of the Challenger. Thus, President Reagan delivered a speech concerning the accident rather than the one that he intended to deliver to the people. This speech was well known as the â€Å"Challenger Address†. The accident had a great impact in the American people. The main reason was stated by the president himself in his â€Å"Challenger Addressed†. There had been a history in space exploration wherein lives were lost, three of them. The accident happened around 19 years before the Challenger tragedy. Although there had been cases of death regarding space exploration, the fact that the tragedy happen in mid air shocked the Americans and the whole world as well. There had never been any accident regarding space exploration that happened a few seconds after the shuttle’s takeoff. Two interpretations can be given why the speech of President Reagan was known as the â€Å"Challenger Addressed†. The first is, it was given that title since the shuttle was named Challenger. However, looking at the contents of the â€Å"Challenger Addressed†, it can be said the word Challenger does not refer to the name of the shuttle but rather to the contents and message of the speech. The president is challenging the nation to continue their search and to never lose heart in space exploration because of the Challenger accident. There had been several components of the speech that makes it effective and appealing to the American people. The very first part of the speech that Reagan used to encourage the people to pursue space explorations was by calling the astronauts heroes, Reagan stated, â€Å"We mourn seven heroes† (Reagan, 1986). He also states that the astronauts were well aware of the dangers that they must face but have overcome it. The president also showed his sympathy with the people especially the family of the astronauts. In order to gain the sympathy and heart of the people, they must know that you are one with them, in spirit and emotions. President Reagan expressed his anguish and mourned not only with the families of the astronauts but with the whole nation as well. At the beginning of his speech, President Reagan sympathized and mourned with the nation in order to appeal to them. However, his tone was developed in the succeeding paragraphs, from appealing to encouraging. He did this by saying, â€Å"The future doesn’t belong to the fainthearted; it belongs to the brave† (Reagan. 1986). These statements surely challenged the people at that time. The impact of the tragedy was reduced in an instant. The president also stated his desire to talk to the people of NASA and to tell and show them that their efforts are well appreciated as well as their sacrifices and bravery and encourage them to pursue their search despite the Challenger accident. Another part of the â€Å"Challenge Address† was the story of Sir Francis Drake, a great explorer who lived by the sea and died on it. President Reagan uses parallelism to connect the present situation into another situation in the past. Thus, those who died in the tragedy are compared to and are paralleled with Drake that creates a good impression for the seven crews of the Challenger. Just as Drake was considered a great man, they too are considered heroes and great explorers. President Reagan ends his speech by saying that the memories of the seven crews will never be forgotten. Thus, showing that they are valued as well as their sacrifices and hard work will never be in vain. This was also important in order to encourage the youth in pursuing to be an astronaut because of the fear that was established by the Challenger accident. It is important to know that your hard work is acknowledge by the society in general in order to be motivated and to pursue a certain career. One of the main factors why the speech was effective was the image, personality and credibility of the speaker. Being the president that time, people will surely listen to what the Reagan has to say. However, in terms of astronomical knowledge and the risk and sacrifices needed on being an astronaut, he cannot be considered a pro. There will surely be different sides of the address; it may either encourage the audience while others may see that the President was in no position to make such address. In every issue, there is always a positive and as well a negative aspect. However, it can be said that President Reagan was able to really challenge the people to search for greater achievements in terms of space exploration and taking the Challenger tragedy as a part of reaching greater knowledge and understanding of the universe, that every quest has its own risk as well as sacrifices that has to be overcome to really success in that particular area. The occasion or the time in which a speech was delivered was also a very important factor for a speech to be effective. The â€Å"Challenger Speech† will not have the same impact if it was delivered without such event, the Challenger tragedy, happening. Thus, the situation or the tragedy is a very big factor why the address made by President Reagan caught the attention of many people by that time and as well as the attention and interest of the people in the contemporary time. There are a lot of things that has to be considered in order to make an effective speech of which four components are primary; the speaker, the audience, the occasion and of course, the speech itself. It can be said that the â€Å"Challenger Address† by former President Reagan is effective because these components had been addressed properly. The speaker is credible enough for the people to listen to what he has to say as well as the occasion needed to gain the attention and interest of the audience. Of course, the audiences were concerned about the situation because of the impact of the tragedy. And of course, the speech itself was well made, something that is expected for a United States President. References Michigan State University Libraries. (No Date). Space exploration.
