Writing An Essay On Gun Violence In America

Writing An Essay On Gun Violence In AmericaIf you are considering writing an essay for an English class, you should consider using a gun violence in America essay sample. These essays can be used in your general or world history classes. They can also be used as reading assignments for your students. If you would like to write an essay on this topic, here is what you should know.Before you begin your essay, you should know the definition of gun violence in America. Basically, this is the history of the misuse of guns in society. As the history of the gun makes clear, guns have been a part of everyday life for many years. From hunting rifles to handguns to automatic weapons, guns have been used for a variety of different reasons and for a variety of different reasons have always been used. There has always been a certain amount of gun violence in the United States.This violence has been a part of American history, even before the Revolutionary War. The violence of the Civil War was a far cry from the guns used by the Civil War era militia.The main debate about the history of guns is whether they were a good or bad thing. Gun violence in America is often a debate between those who say guns can be used for good and those who say they can only be used for evil. Gun violence in America, however, has been used to promote a certain political agenda.When people were debating the use of the gun, there was a political group that used the gun violence in America to promote their cause. After the Civil War, they formed the Second Amendment to the Constitution, which enshrines the right to bear arms as one of the fundamental rights of American citizens. So, for some, the use of guns to control society has a history of promoting the cause of political parties.Your essay can discuss this history with you and your class. It may not only be the history of the gun; it could also be the history of the gun laws in American history. You might also want to make this a debate that go es back to the founding of the country.It is up to you, and your students, to make your essay about this subject relevant to the discussion.

Life lessons that can be found in Star Wars

Life lessons that can be found in Star Wars 7 Things to Learn From Star Wars Cant wait to see the glorious return of Han Solo and the Millennium Falcon? Lets take a look at the wisdom of the Jedi, The Force and Master Yoda, to find lessons Star Wars can teach us about life. (But even if the words In a galaxy far, far away, dont ring a bell for you, the rules are universal, so feel free to apply them in order to make your life better. And May The Force be with you! Live the life you want to live (you can do it!). Do or do not there is no try. Yoda in The Empire Strikes Back Theres no reason to waste your life being stuck in fear and uncertainty. Youre free to be whatever you want to be. Just make a decision and stick to the plan. Remember, The Force is on your side. Keep close to people who have faith in you. I find your lack of faith disturbing. Darth Vader in A New Hope Warning! Pessimism is contagious. Stay away from people who make you feel bad about yourself. In other words, say NO to energetic vampires. The rule is pretty simple: be with those who support you and believe in you. Be honest with yourself. You know what the right thing to do is. Already know you, that which you need. Yoda Let your heart guide you. You carry all the answers within. Just listen to the voice of that inner Yoda of yours, and youll find the way. Nothing is impossible. C-3PO: Sir, the possibility of successfully navigating an asteroid field is approximately 3,720 to 1. Never tell me the odds. Han Solo in The Empire Strikes Back Even if your odds of success are really (I mean, REALLY) small, dont let this fact stop you from staying true to yourself and to your heart. You succeed by overcoming failures. Strike me down and I will become more powerful than you can possibly imagine. Obi- Wan Kenobi in A New Hope The road to success is paved with failure. No matter how hard you try, you cant avoid mistakes. After all, were all humans here, arent we? So, the point is to make proper conclusions out of those mistakes and to prevent them from happening in the future. Dont let fear be your guide. Fear leads to anger. Anger leads to hate. Hate leads to suffering. Yoda in The Phantom Menace When youre scared, youre vulnerable. You cant see clearly if youre paralized with fear. Keep in mind that very often our fears are causeless. Just pull yourself together and dont let the imaginary monsters impact your life. Humor always makes it better. (as garbage compactor closes in) One things for sure, were all gonna be a lot thinner. Han Solo in A New Hope Freaking out is a common reaction when something goes wrong. But will it help you to solve the problem? Doubtly. Humor, instead, will make you feel way better and give you some time to think the situation through. Humor is the key to success (and to girls hearts as well ;))

Essay on Gender Equality Example | Topics and Well Written Essays - 1500 words

On Gender Equality - Essay Example Not just the physical differences of these two, even at their physiological responses and to other fields. The society is just having misconception about the differences of the two sexes that is why conflicts arise. We can look closely to how we can link these two sexes. But to do that it is better if we recognize first what are their differences for us to be able to connect them and resolve the reasons why conflicts arise. In other words, let us look at the both sides on them and settle at the middle and understand their reactions or responses. When it comes to physical appearance men has more defined muscle structure than women. They are the one who are much capable of lifting heavy things as compared to women because their physical capacity is fit for such work. The brain structure of men is different from women. They have thinner corpus callosum. This is the one that connects the two halves of the brain. The left side of the brain is the one responsible for analytical thinking. And this is when the boys can level up to the scores of women because men are good with numbers (Turner, 1997). When it comes to sexual urges, men are more visual than women. Visual things can usually trigger their urges compared to women. When it comes to listening, men usually have different kind of behavior. In the research of Deborah Tannen (1990), she found out that men will usually eye on something else while listening to somebody. When you talk to them they don't look at you straight but will be eyeing other things in the surroundings. She also found at his research that even at the development of men will stand as the evidence of how different they are to women. They usually establish bonding with other boys with physical activities; they don't make talking as a medium for closeness to other boys. When it terms to command making, men are more direct to what they want and the orders that they give according to Theiderman. She even elaborated that even in asking question there is this line that separates men from women. Men are not into details and will ask fewer questions. Men ask questions because they want to know something. Their purpose of asking is plainly to gather information. Women Physically, women have less muscle definition. Instead they are built for the purpose of conception and therefore bear the gift of carrying their young. As to brain structure, women are have a thicker corpus collusom and are therefore capable of multi tasking as compared to men. In terms of sexual urges, women are more into touch than visuals. They are easily aroused when touched and not just by visuals. In terms of listening, women look at their partners when listening. They set their eyes to there friends when listening because it is their way of showing that their attention is set to conversation. As to making commands, women are softer in giving orders. They usually use tag lines and will usually use phrases that ask for confirmation but in away suggesting her own idea or asking for others to confirm with her, (Thiederman). Girls establish a different medium of bonding with other girls. They indulge their time to talking as establishing closer relationship with other girls, (Tannnen, 1990). Girls usually exchange secrets and talk about a constant topic as compared to boys. For them, if they spend time for talking with other girl

An inconvenient truth (Movie report) Movie Review

An inconvenient truth ( report) - Movie Review Example Some men heeded Marsh’s call and forest reserves were established soon after. Meanwhile, John Muir, founder of the Sierra Club helped in the establishment of the Yosemite and Kings Canyon National Park because he believed that all living things had a part to play in the subsistence of the whole world, and must be preserved because they exist. From these early efforts sprung worldwide environmental organizations calling for a more ethical use of the earth’s resources. By 1972, out of the United Nations Conference on the Human Environment, the Stockholm Declaration was born The Declaration recognized man as both a â€Å"creature and molder† of his environment, acknowledged the role of the environment in the sustainability of mankind, and mandated man to protect his environment (United Nations Conference on the Human Environment). It demanded accountability in all citizens and communities, enterprises and institutions to shape the future of the environment. From the early awareness of the importance of nature to man’s survival came an understanding that the Earth is a living being. In 2010, the Earth Declaration (World People’s Conference on Climate Change and the Rights of Mother Earth) afforded Mother Earth with equal rights as humans. It was perhaps the first document to compel nations to reco gnize the interdependence of life on the planet and that â€Å"in an interdependent living community it is not possible to recognize the rights of only human beings without causing an imbalance within Mother Earth† (World People’s Conference on Climate Change and the Rights of Mother Earth). I mention these developments in the environmental movement because I wish to believe that climate change will not end the world, instead, it will help man discover who he truly is. George Mash once said, The fact that, of all organic beings, man alone is to be regarded as essentially a destructive power, and that he wields energies to resist which,

knockout mouse

knockout mouse Knockout Mouse 1. Introduction Generally, DNA was first transferred by design into an organism and expressed as protein, therefore the potential of the tool that was being discovered must be found quickly by the scientist. Early experiments were limited to bacteria and viruses, but soon after the field of experiments were enlarged to those on animals and plants. (E.Hill, 2002). This topic, â€Å"knockout mouse† relates to the field of genetic engineering which further delves into a more specific technique called transgenic technology. â€Å"Knockoutscience.com†(2009) analyses that transgenic technology refers to the alteration of a certain genomic DNA of an organism in genetic engineering. As the result, both offspring of a transgenic organism and the parents (homozygous) will share the same genotype. The most common type of transgenic organism used in research is the knockout mouse, thoughknockout rats andknockout rabbits have also been developed. A knockout mouse defines a mouse which is being genetically engineered by turning off one or more genes through a process called gene knockout. â€Å"Genome.gov â€Å"also explains that a knockout mouse is a laboratory mouse in which researchers have inactivated, an existing gene by replacing it or disrupting it with an simulated piece of DNA. The loss of gene activity often causes changes in a mouses phenotype, which includes appearance, activities and other observable physical and biochemical characters. â€Å"Knockoutscience.com† (2009) also elucidates that it has become routine to develop knockout mice with disruptions in specific genes. By observing the resulting phenotype, scientists are able to view the effects of this gene disruption from these knockout mice. It is true to say that the phenotype is a direct result of the gene knockout and can offer evidences as to the biological role of the gene, but rarely the phenotype can also be the result of compensatory or indirect effects of the gene knockout. Sometimes the result obtained in a phenotype can be completely unrelated to the disrupted gene. Additionally, some gene knockouts create alethal phenotypewhere the organism fails to develop in utero, making in vivo studies exceedingly difficult. It was claimed that this technique may help to solve dopamine-related neurological illnesses.(Carol A.T, 1996) The technique allows transgenic animals that lack of a certain gene or its associated protein product to grow. In experiments with mice, researchers were able to knockout the animals dopamine transporters, causing the mice to behave as if they had been given huge doses of cocaine or amphetamine. Walinski.H(2009) states that knockout mice have different way of uses. First, the specific functions of particular genes can be tested and the regulation of these particular genes can be observed. The effects of a particular gene can be determined by examining what is happening in anin vivo model, we are able to determine the effects a particular gene may have. These effects would be impossible to observe in a culture dish. Another useful application of knockout technology is in biomedical research and drug development. Knockout mouse can be used to study the evolution of thousands of genetically based diseases at the molecular level in order to seek for the best medications that act on that gene. For Example, Lili.X and Asok.C (2005 ) both agree that Duffy positive and Duffy knockout mice have revealed both human malaria parasite Plasmodium vivax and mouse malaria parasite Plasmodium yoelii by using parasite invasion. Furthermore, the knockout technology may lead to the discovery of the next generation of blockbuster therapies for curing numerous diseases based on novel targets from the human genome. 2. Background Genetics Timeline for the key events in the history of knockout mouse 1900 Japanese fancy mice became mutant resources for mouse genetics. 1915- The first verterbrate linkage (mapping) was discovered between albino (c) and pink-eyed dilution (p) loci in the mouse. 1923- Discovery of X-ray induced mutations in mouse before the phenomenon was confirmed in fruit-flies. 1980- Specific-locus tests were conducted extensively in the mouse with various chemical mutagens, including N-ethyl-N-nitrosourea (ENU). 1981-1991- knockout mice are established. 1981- The first embryo stem (ES) cell was identified in the mouse. Martin Evans and Matt Kaufman in Cambridge, U.K., isolate mouse embryonic stem cells, which can develop into the full range of tissues. 1982-Transgenic mouse technology was established through the generation of the â€Å"giant mouse† mutant. 1985- Introduction of the Cre-loxP system by Brian Sauer act as temporal control of transgenic gene expression. 1987- Mario Capecchis team at the University of Utah describes a method for making knockout mice, as does Oliver Smithiess group at the University of Wisconsin. 1989- First knockout mouse was made by combining ES cell and gene-targeting technologies. 2007- International Knockout Mouse Consortium was organized and the Banbury II meeting was held in Brussels, Belgium. Nobel Prize for Physiology and Medicine was awarded for the development of mouse knockout techonologies. 3. Genetic Technique There are several method to produce knockout mouse, such as gene deletion, homologous recombination method, pronuclear microinjection and gene targeting. However, only gene targeting will be mentioned herein. Gene Targeting is the elimination or alteration of a genes function. One of the advantages of gene targeting is a mutant allele can be mended by substituting a wild-type allele over the mutant one in its normal chromosomal location, and such technique known as gene replacement. In this way, both position effect and the DNA rearrangements associated with ectopic insertion can be prevented, as a single replication of the gene is inserted in its normal chromosomal environmental. (Griffiths.A and Susan R.Wessler,etc, 2008). 4. Social Issues Recently, the evaluation of animal and human welfare as it may be affected by biotechnology is becoming a hot issue. The lack of an conscience and the information of the processes involved is one of the most important fact. ( Marie.B, 1997) Marie.B (1997) also states that the moral evaluation process is complicated by the fact that many techniques and developments in biotechnology are appropriate for patent. Some of the biotechnologists are reluctant to reveal appropriate information is understandable. Therefore, education concerning transgenic animal care and utilize is indeed very importance, involving the careful consideration of the reasons for manipulating the genome of any organism as genetic engineering is a dangerous and sensitive social issue. ( Marie.B, 1997) Pros and Cons of Knockout Mouse Advantages Disadvantages Provides important clues about what that gene normally does because human share many genes with mice. (Genome.gov, 2009) Limitation of the utility of knockout mice as models of human disease. (Walinski.H, 2004) Gives better understanding and observation of the characteristics of knockout mice. ( Genome.gov, 2009) The lack of adult mice limits studies to embryonic development and makes it more difficult to determine a genes function in relation to human health. ( Genome.gov, 2009) Gives information that can be used to better understand how a similar gene may cause or contribute disease in human. ( Genome, 2009) The gene that being examined might serve a different function in adults than in developing embryos, giving a false information. (Genome, 2009) Useful in studying and modeling different kinds of cancer, obesity, heart disease, diabetes, arthritis, substance abuse, anxiety, aging and Parkinson disease. Fails to produce an observable change in a mouse or may even produce a different characteristics from those observed in humans in which the same gene is inactivated. ( Genome.gov, 2009) Offers a biological context in which drugs and other therapies can be developed and tested. Producing custom knockout mice is very expensive. It can be from 3000 to as much as 30,000 (Walinski.H, 2004) Useful in drug development and helps to discover the next generation of blockbuster therapies for curing numerous diseases based on novel targets from the humane genome. (Walinski.H, 2004) The cost of equipping and maintaining such a facility is usually very high. ( Walinski.H, 2009) 5.0: Conclusion In conclusion, it is clear that knockout mouse offer a lot of benefits for us. Therefore, a thorough discussion of biotechnology issues is needed, as concurrence must be practiced as to protect transgenic animals. The field of transgenic animal biotechnology is likely to rise as the techniques develop further and will link to more applications by using many more animal species. Thus, it is important that the welfare and ethical concerns must continue to evolve. (Marie.B, 1997) In short, technology essentials together with thoughtful ethical decision-making are equally important to maintain the balance of living creatures. 6.0: Bibliography * Connor A.B, 2007, Schematic and Time Line for the Generation of Knockout Mice, Viewed 25 January 2010, http://web.mit.edu/ki/facilities/transgenic/services/timeline-complete.pdf * Davidson, NC 28036, Homologous Recombination Knockout Mouse, Department of Biology, Davidson College, viewed 15 January 2010, http://www.bio.davidson.edu/Courses/genomics/method/homolrecomb.html. * Eisen, Eugene J, 2005, Mouse in Animal Genetics and Breeding Research, viewed 25 January 2010, http://site.ebrary.com/lib/sunway/docDetail.action?docID=10173945p00=knockout+mouse * Garagna, S, 2004, Mouse Genetics after the Mouse Genome, Viewed 25 January 2010, http://site.ebrary.com/lib/sunway/docDetail.action?docID=10070304p00=knockout+mouse * Genome.gov, 2009, Knockout Mice, Viewed 25 January 2010, http://www.genome.gov/12514551 * Genoway ( 2006), Gene deletion, conditional knockout mouse, viewed 11 february 2010, http://www.genoway.com/conditional_knock_out_mouse.htm * Griffiths.A.J, Wessler.S.R, Lewontin.R.C and Carroll.S.B (2008), Introduction to genetic analysis, W.H,Freeman and Company, England. * â€Å"Google docs†, 2010, Gene targeting construct, Viewed 25 January 2010, http://74.125.153.132/search?q=cache:j6mj7wNqd7gJ:tmc.ctrl.ucla.edu/targeting.pdf+history+knockout+mousehl=engl=my * Hudson, 2010, Taconic enters marketing pact with Transposagen Bio for knockout rat models, viewed 25 January 2010, http://www.pharmabiz.com/article/detnews.asp?articleid=53683sectionid= * Marie.B (1997) Transgenic animlas, viewed 11 february 2010,http://www.ccac.ca/en/Current/Current_Transgenic.htm * National Center for Biotechnology Information, 2007, What is transgenic technology?

Acoustics :: acoustic acoustics sound

The concert hall is one of man's greatest joys; enjoying a fine symphony composed by the worlds greatest, performed by a world class orchestra. For months afterwards, the borgoise attendees will speak of the energy of the conductor, the orchestra responding to him, the power of it all. The crescendoes, the diminuendos, the stark silences between movements, the clarity of the soloist above the rest of the orchestra. Little do they know that were it not for the meticulous consideration of the architect at construction time, the patrons would not feel that they were getting their money's 'worth.' The architect is tapping into the world of acoustics; in this case, achieving the best possible sonic experience through differing techniques : different materials, certain shapes of rooms, sound traps, etcetera. Acoustics and sound, like so many physics branches, starts out relatively simple and quickly becomes a gigantic headache. Massive amounts of planning must go into a large structure such as a concert hall, a dance hall. Even small structures, such as the phonebooth, have hours of careful planning put into their design, in order to achieve the desired effect with the varied sound sources. This page is designed to inform the reader in the basics of acoustics, using the theory behind acoustics and the examples of the concert hall and the dancehall. Technically, the definition of 'sound' is a pressure wave in an elastic medium. This means that our pressure wave can be present in air, water, wood, steel... many different solids as well as air (and liquid). One of the most common units of measurement of sound is intensity, or the rate at which sound energy is being transmitted into the medium. (low sound intensity would be something like somebody clapping between movements, high sound intensity would be the applause after Beethoven's 9th) The unit of intensity is the decibel, or db. We use a logarithmic scale to measure these, as it is difficult to understand the range of the decibel in linear terms. Other units of measurement are the period and the amplitude of the wave. As we see in the graphic, we have the graph of time versus sound pressure, with our little wave traversing it. The amplitude is the highest value the graph reaches before descending again, while the period is the amount of time it takes for the wave to complete a full cycle. Other terms of note for the diagram are compression, which is represented by the parts of the graph in the positive region of sound pressure, and rarefraction, which is represented by negative pressure.
