Methaqualone Essays - GABAA Receptor Positive Allosteric Modulators

Methaqualone Methaqualone is a drug that has hypnotic and sedative properties. Although Methaqualone is not considered a barbiturate, using the drug can produce similar results. Common street names for Methaqualone are Quaalude, Lude, Quay, Quad, Mandrex and Sopors. Methaqualone can be injected, and also taken orally. Methaqualone commonly is manufactured in tablets or capsules. The drug can also be found in brown, gray or black tacky powder. An average dose of Methaqualone is about 3 grams. This depends on the person's body height, weight, the use of any other drug, such as alcohol, and the tolerance built to Methaqualone. Within 4-8 hours of taking Methaqualone, the user may experience slurred speech, disorientation, lack of coordination, and increased reflex time. Methaqualone is also commonly used because it causes drunken behavior without the odor of alcohol. The drug also relieves tension, mental stress and anxiety. The possible long-term effects of Methaqualone are psychological and physical dependence, cardiac and respiratory depression, and the reduction of mental activity. The withdrawal symptoms of Methaqualone are anxiety, insomnia, tremors, convulsions, and possible death. The effects of Methaqualone when overdosed are unpredictable, which makes the drug even more dangerous. Overdose by Methaqualone is also more difficult to treat than most barbiturate overdoses. These effects range from cold and clammy skin to a possible death. People that lived through a Methaqualone overdose have also experienced shallow breathing, dilated pupils, and coma. When introduced in 1965, Methaqualone was legally used as a sedative-hypnotic. Doctors prescribed Methaqualone to patients who needed the relief of side effects that were associated with over-stimulation or the withdrawal of other drugs. By 1972, the abuse of Methaqualone was prevalent among both teenagers and adults. "Luding out", or orally ingesting Methaqualone with liquor became popular with teenagers. This made the abuse of Methaqualone twice as hazardous because it increased the effect, as well as the danger. Adults used Methaqualone to reduce anxiety, and as a sleeping aid. Because Methaqualone was widely abused, in 1984 the drug was made illegal in many countries, including the United States. Although most of the effects of the drug are known, Methaqualone is still one of the most widely abused drugs. The most common dangers from abusing Methaqualone are due to car accidents. Because Methaqualone causes faulty judgement and drowsiness, it is very easy to injure or even kill yourself or others in a car accident. Bibliography 1. Kunz, Jeffery and Finkel, Asher.

Chemistry of Fireworks - Smart Custom Writing Samples

Chemistry of Fireworks - Smart Custom Writing Irony and Satire in Jane Austen novelsIrony, satire, and parody are the soul of Jane Austen’s novels because of the humorous aspects of life she presents in her novels. The aspects are visible to good sense in their contemplation of erroneous judgments. Both novels present the reader with a several characters that play different roles in bringing out the aspects of humor and wit in the two novels. It can also be noted that the stories unfold from different angles as the author brings out several vices that are either morally or ethically unaccepted.  Ã‚  Ã‚   Irony is the hall mark of her style because this irony is not merely a particular way of saying or creating things (Bhattacharyya 80). Irony in this tale is rather the expression of the infinite within a man who has at once a delicate, sensitive, and subtle perception of the contrasts and contradictions with which human life is filled. On the other hand both novels make use of one common device throughout that is satire. Satire is a literary attitude used to make pleasurable aspects of character vices or weakness. This is done with the purpose of modifying the subject being attacked. Besides this satire utilized in the story confirms how excitement is poked at things that are collectively unacceptable and downplayed, creating an ironic sense of wit. Quintero says that pride and prejudice demonstrated satire when women in her tale were supposedly animated by sentiment (290). According to Quintero the definition of satire as a genre meant to expose vices for the purposes of correction lingers on in this novel (290). In addition Bhattacharyya says that pride and prejudice tale is not laughter provoking but they have a rippling sense of pleasure behind them (80). In this novel satire connotes moral purpose but the author never lashes human follies. Colebrook says that while irony in the pride and prejudice and zombies consequently delimits human life by positing an elevated concept that is not realized, satire examines life and its inherent propensities (108). In this tale Jane Austen (1775-1817) parody is depicted in the way several characters take their local sentiments for universal truths. Colebrook says that â€Å"the author displays the blindness of the characters who believe themselves to be in simple possession of either a moral law or a social code† (108).   While satire brings out individual characters against the morals of parody in this novel is portrayed by the vanities and tendencies of human nature and they also present characters that arrive at fulfillment only through knowing and reflecting upon social nature of man (Colebrook 108). On the other hand Austen shows satire through the art of fiction and recognition through examining the follies of others with a full perception of our own weakness. In this story satire unlike parody assumes the common ground of man and therefore works against the traditional aim of irony and elevated or urbane point of view above and beyond natural life (Colebrook 108). Moreover, Bhattacharyya also indicated that in the story pride and prejudice, irony is a mode of speech in which the implied attitudes or evaluations are opposed to those literally expressed (81). The tale is in many occasions irony is a contrast between reality and illusion. For example Bhattacharyya says that the first sentence of the novel is tinged with irony as the sentence runs â€Å"it is a truth universally acknowledged that a single man in possession of a good fortune must be in want of a wife† (81). This is not a truth that is universal to every man because the contrast appears to be true in most cases. On the other hand, satire is also demonstrated in the novel since the author does not reveal enough about what Darcy is supposed to be thinking. Walder says that â€Å"in Elizabeth’s crucial conservations with Jane, the antithetical technique, contrasting Elizabeth’s satire with Jane’s candor (231). Satire is depicted in the novel because as a whole intelligence is represented as faulty in the novel. The readers admire Elizabeth’s wit and sharing her lively and satire vision. Walder further says that reformation is not complete until near the end of the novel and everyone notices that the second, less satire and extrovert half of pride and prejudice is less enjoyable than the first.   Bhattacharyya says that â€Å"irony is being used as an instrument of revealing the difference between appearance and reality is always a source of inspiration and amusement† (81). This is depicted when Darcy remarks about Elizabeth that â€Å"she is not handsome enough to tempt me† and soon after gets captivated by a â€Å"pair of fine eyes† of Elizabeth† (Bhattacharyya 81). In addition irony of character is even more prominent in the novel than irony of situation. For example â€Å"Elizabeth prides herself on her perception and disdains Jane’s blindness to the realities is herself quite blinded by her own prejudices† (Bhattacharyya 82) The novel pride and prejudice and zombies it is a complete parody but then it comes out in a complicated form. Austen has mirrored the original work effectively enough so that the flow is fresh and funny.   In addition, Ross says that the novel explores the purpose of parody that ranges from a playful imitation to harsh satire (49). Compared to irony, the author also portrays successful parodies in which the element of celebration is clearly shown. For example in the novel Pride and Prejudice and zombies parody is depicted when Darcy says â€Å"which do you mean? And turning round he looked for a moment at Elizabeth till catching her eye, he withdrew his own and coldly said â€Å"she is tolerable but not handsome enough to tempt me; I am in no humor at present to give consequence to young ladies who are slighted by other men† (Austen 13). In this case the style in which parody is been shown is pretentious one because it is deflated by mockery hence its function is challenged so as to renovate and renew it (Ross 49). Like satire, irony in pride and prejudice is clearly depicted when a rich and influential man falls in love with a relatively poor and powerless young woman. It appears as a surprise to Elizabeth that Darcy finds himself in love with her while the author Austen makes it clear how wonderful it is that such a man should fall in love at all (Polhemus 29). In the beginning of the story there is more irony because the match was not very compelling because the reason why he fell in love with Elizabeth and marry her but at the end the match between the two looks perfectly reasonable. Pride and prejudice shows how from historical perspective the association between the sexes where men could seem princes and women scullery maids. The ironic part of the story is depicted on the basis that though Elizabeth comes to love him by the end it is not at all clear that   she ever falls in love with him because in their romance man falls in love with woman and that fall into love is the fortunate fall of Austen’s erotic faith (Polhemus 29). The story further shows the readers that the world is often a sordid, dull, menacing, and disappointing place without love. The irony is that the power of love in pride and prejudice works to generate faith, hope, and charity. Parody on the other hand is depicted when the story explores that Darcy’s love for Elizabeth curbs his arrogance and makes him a kinder and better man (Polhemus 29).  Ã‚  Ã‚   Among the utmost and most exhibited satires in the story is illustrated through the most humorous man Mr. Collins. Mr. Collins character is rather hilarious in the entire text because of his apparent foolishness and his lack of understanding to his vices. Mr. Collins persistently acquaints himself with people of the superior class than his, for example Lady Catherine and Mr. Darcy who are regarded as high status people. He relates so much with these two people by the means of continued trips to the Rosins estate and Balls. Mr. Collins began to relate himself with Lady Catherine and Mr. Darcy, making himself comes out as higher class individual than he really is. With this phony sense of being Mr. Collins indisputably makes a fool out of himself giving the readers a clear picture of satire (MRU database). Like irony, satire is employed in the entire novel Pride and Prejudice. This is because Austen starts to put across her own dissatisfactions of her own personalities and also reveals her own dilemma with the way in which society was footed upon class during her era. This application of satire becomes supplementary than just a mechanism that conveys humor to the readers. It is also a device that shows the communal issues that were there in Victorian England in Austen’s time making it an essential element to the story. Satire is employed in Pride and Prejudice by the author to show the shortcomings in moralities and ethics of the subjects that Austen criticizes of. Satire is thus used hit at the characters in order to bring new changes. The type of characters she ridicules is ignorant in the author’s context. For example Jane Austen condemns Mr. Collins causing her to bother and satirizes him. Because of staying with Lady Catherine, Mr. Collins has demoralized himself.   This is because he imagines and speaks highly of individual’s superior than himself, such as, Lady Catherine DeBourgh. This is demonstrated when he was invited by Lady Catherine Mr. Collins tells Elizabeth who he was proposing to "Do not make yourself uneasy, my dear cousin, about / your apparel. Lady Catherine is far from requiring that elegance of dress in us which becomes herself and / daughter. I would advise you merely to put on whatever / of your clothes is superior to the rest / ...she likes to have the disti nction of rank preserved" (Austen 137). Austen in both novels illustrates that satire is the lesson while parody is the game. Ross says that parody can never have the force of satire because it seeks to undermine established attitudes in the author’s work (49). Darcy for example shows the original form of parody of the existing social order but it can be seen as an authorized transgression of norms. For example Elizabeth in both novels was displayed as the anti-heroine of romance a parody that accounts for the tough personality of the conqueror and her challenging of modesty by conversation and action (Austen 13). The characters and incidents in the novel pride and prejudice are used to give the audience a taste and critical sense of parody because every incident unfolds in a manner in which it advances the progress of the story (Austen 13). This can be elaborated when â€Å"Darcy walked off, Elizabeth felt her blood turn cold because she had never in her life been so insulted hence the warrior code demanded she av enge her honor† (Austen 13). Bhattacharyya says that it interesting to note how the author deals with parody, satire, and irony in both novels. Bhattacharyya says that â€Å"the readers can notice that the Elizabeth-Darcy story is told with surface romanticism and it contains most of the verbal irony of the novel† (89). On the other hand it is important to note that â€Å"the Wickham-Lydia and Charlotte-Collins episodes are treated romantically with a solid foundation in social realism and with rather sordid and happy implications which in them the functions of parody comes out clearly† (Bhattacharyya 89).   Another example of parody is through Darcy’s realization of his mistake that gradually leads to reconciliation between Jane and Bingley. Besides this we notice that Lydia’s sudden elopement with Wickham leads to the marriage between Elizabeth and Darcy and also Charlotte’s sudden acceptance of Collins’s proposal leads to theirs (Bhattacharyya 89). Parody is demonstrated in the above series of events because one incident leads to the occurrence of another event (marriage) between the characters in the novels. In this context irony is evident. This is because the story becomes uncharacteristically clumsy from this point. This is because irony is illustrated when the reader realizes that the proud man is writing meekly to the girl who has rejected him unconditionally. Bhattacharyya says that satire is demonstrated through the novelistic technique of seduction as a suitable climax which Austen shows a standard chase by an outraged father, a friendly uncle and a now impeccable hero who makes devoted efforts to wed the scheming profligate Wickham to the innocent victim Lydia (90).   In contrast to parody, satire is demonstrated by Austen in pride and prejudice and zombie when Charlotte says â€Å"I wish Jane success with all my heart and if she were married to him tomorrow I should think she had as good chance of happiness as if she were to be studying his character for a twelve month. He further comes out clearly and says that happiness in marriage is entirely a matter of chance and it is better to know as little as possible of the defects of the person with whom you are to pass your life† (20). Satire in this passage is evident because it appears like he is offering a lesson to Jane of what to do and learn when she enters into marriage. In pride and prejudice as well as pride and prejudice and zombies, Jane Austen has given a multitude of characters that bring out the picture of irony, satire, and parody. This is because according to Bhattacharyya the characters are perfectly discriminated from one another as if they are the most eccentric of human beings (94). There is also a sense of pervasive irony in the characters of Jane Austen’s novel. Bhattacharyya says that â€Å"the irony is betrayed in her portraiture of the characters of Elizabeth, Darcy, Collins, Wickham and others† (95). Irony is the soul of the author’s comic view of life because she recognizes the antithesis in human experience that is the contrast between reality and appearance (Bhattacharyya 95). Satire is illustrated through Collins character who besides being a humorous character. Bhattacharyya says that had it not been for Collins, Elizabeth and Darcy could not have come together as they do in the end (97). This is because it was Collins who first gave the information of engagement of Darcy and Elizabeth. Parody on the other hand is demonstrated through Mrs. Bennet who is seen as a woman of mean understanding because though she has been married for twenty years she is shown as unable to judge her husband (Bhattacharyya 97). Her remarks adds parody to the novel and at the same time she does not see the stupidity of Collins but tries to force her daughter to marry him though without success. In conclusion, the functions of satire, parody and irony in the two novels is evident. These three aspects in the two novels help us to gain a good understanding of the characters. They bring humor to the novels thus the comic characters used by the author are significant in different angles of the novels. They act as a guide and to an extent they portrayed in such a manner as to make satire, parody, and irony in their portraiture not too blatant. Satire, parody, and irony do not just give the picture but lets the reader make his or her own judgment. Works cited Bhattacharyya, Jibhesh. Jane Austen’s Pride and Prejudice.

Give an example of a law that you think attempts to reflect an ethical Essay

Give an example of a law that you think attempts to reflect an ethical value - Essay Example Typically, it reflects an ethical value because it protects employees against unethical behavior in the working environment especially in situations where a disability will not hinder the performance of a job and hence, is appropriate. It will compel managers to consider not only legal aspects but also what they, the society and employees consider to be ethical. On the other hand, the Fair Minimum Wage Act (2007) emphasizes on legalities but does not reflect ethical values. For example, it has not compelled Nike to stop paying substandard wages to its foreign workers and improve their working conditions. This law is inappropriate because it assumes that so long as Nike meets the minimum wage, it is not illegal to pay law wages and in appalling working conditions. It does not consider the fact that the employer needs to provide safe and conducive working environments apart from meeting a stipulated minimum wage (Lopez,

Sustainability Essay Example | Topics and Well Written Essays - 1500 words

Sustainability - Essay Example The condition of the planet as well as its ecosystems is wholly depended upon the present as well as the past human activity. This is determined by the interplay of three factors namely the economic, political and social (Hak & Et.Al, â€Å"Sustainability Indicators: A Scientific Assessment†). There seems to be substantial debate over the term ‘sustainability’. Some defines it as a contested and complex concept, however for others; it can be defined as the capacity of something that can be continued for a long period of time. Issues Important for Urban Land Use Economic Sustainability The point worth noticing is that none of the economic systems can be sustainable until and unless it ‘accommodates’ the ecosystem in which it depends. The current system that is based on the notion of continuous economic expansion on planet seems to be damaged. Therefore, there is requirement of applying human creativity to the goals which is to use the natural resources in a productive and efficient manner in order to meet their needs. This goal can be considered as being completely dissimilar from ‘exploiting natures’ and the Third World people. ... The most important consideration in regards to the ecological sustainability is that it needs to be pursued for the human as well as for the species which are around 10-12 million on the planet (Sutton, â€Å"Ecological Sustainability†). To make the concept simpler, the term ecological sustainability can be interpreted as any activity that takes place on earth has to generally continue forever. Ecological sustainability can only be achieved if the activity does not destroy any resources through which the activity actually takes place. There isn’t requirement of inventing the sustainable environment from scratch since it can be modeled by the human in order to simulate natural eco-system. It can be revealed that there are key principles which need to be adhered to for achieving the ecological sustainability. The most important point to keep in mind is that there is requirement of changing the habit of using the resources as if they are infinite by the society. Moreover, greenhouse gas emission needs to be minimized to a greater extent and also there is requirement for some kind of new and improved economic ways that would be based upon the clean, glass technology (Carrie & Danielle, â€Å"General†). Social Sustainability The term social sustainability has a wider implication upon the lives and health of the people of the society. It tends to deal with the complex issues, for instance health, equity, social inclusion and livability. If the community is to be sustainable and function properly then in that case the basic needs of its resident have to be met. A good sustainable community is the one that has the ability to maintain and build on its own resources. On the other hand, it

Primary education- reflective practioner Essay Example | Topics and Well Written Essays - 2000 words

Primary education- reflective practioner - Essay Example Action research, otherwise known as participatory research, collective inquiry, emancipatory research, action learning, contextual action research, depending on the theme (O’Brien, 1998), is an â€Å"inquiry or research in the context of focused efforts to improve the quality of an organization and its performance† (North Central Regional Educational Laboratory, n.d.). Unlike ordinary research, the members of the said institution who design and conduct action research are also part of the study themselves. They find ways to develop how things are done in their fields. The process of action research which consists of four steps which are planning, acting, observing and reflecting, as presented by Stephen Kemmis (cited in O’Brein, 1998), makes it very useful in developing methods and materials in schools as it presents new ideas and options to teachers. It allows them to evaluate outcomes of their teaching strategies and lay these down to fellow mentors to lessen drawbacks among their students. Through this, further possible needed changes and amendments in the institution’s educational programs and syllabus can be carried out. In problems previously and presently experienced in the â€Å"real world,† disputes between the â€Å"insider-outsider researchers† continue. Academicians debate about the pros and cons of one over the other and vice-versa. Issues regarding sensitivity to the problem, presumptions and assumptions, and objectivity are pointed out by the opposing bodies. Researches conducted by â€Å"outsiders,† or those not actually a part of the studied group, are said to merely â€Å"add to the knowledge in the field and to publish in peer-reviewed scholarly journals† instead of giving precise aid to the group being assessed (Collet, 2008). To add to the complications pointed out about â€Å"insider-outsider researchers,† Bridges (2001 cited in Collet, 2008) perceives that even if the individual is dubbed to be an â€Å"insider,† by being a researcher, he

Live Motion Capture

Live Motion Capture The method that records a live motion event, which then is being translated into usable mathematical conditions by tracking a number of key points that are being combined in space over time to get a single three-dimensional representation performance is called Motion Capture. To simplify the meaning of this technology, it enables the use of real performance to a digital one. Everything that exist in our world and has actual motion could be then captured; each moving part of that subject has its key points that provide the motion. When that technology is being used on a human as an instance, key points are the actual joints and they work as pivot points and connections for the bones. Usually when that is being done, all of the sensors, potentiometers or markers identify the points and that transmits the data to the main device. The performance that is being used to get a character to life is called performance animation, and motion capture is related to the actual technology that coll ects the motion. To conduct that, motion capture needs to be done and then that is being transmitted to the 3D character. That being said, mocap obtains all of the information that represents motion, while the performance animation on the other hand, is the final deliverable of a character created by the performer. Menache, A. (2011). Understanding motion capture for computer animation. Burlington, MA, Morgan Kaufmann. Motion Capture is known as Motion tracking and in most cases as `Mocap`, in any case it is actually 3D Animation. The process in which recordings of human movement are translated into digital form by recording every pivot point on the actor/actresses body. After this footage is filmed it is then translated onto a 3D model. Since the 1970`s that technology has improved drastically and Performance Capture is a term referred to when Motion Capture animates small human features such as fingers, expressions and facial features. That process is actually very time consuming. For instance, the performance capture in 2009 20th Century Fox award winning film â€Å"Avatar†, took over 15 years to create and the reason for that is that the amount of sensors that were used to portray these expressions was immense. The concept of animation dates back to more than a thousand years ago when Chinese zoetrope-type device was built to produce the illusion of motion from a burst succession of stat ic images. To present, everyone is familiarized with the different types of animation, from traditional hand-drawn image frames, to the Claymation or technology of Stop Motion. Until the arrival of the Computer Graphics that has not shifted for all that time. The most known categories of character animation to date are three. The first category consists of algorithmic and model-driven approaches. An example is the dynamic physics-based model, like reverse pendulum. The second category is the digital key-framing and hand driven, a workflow alike the original animation creation but with the assist of 3D creation tools. Motion Capture is the last category, it was first developed in the late 1970`s but it hasn`t been recognized as a revolutionary animation technique until the mid 1980`s when it was used for entertainment purposes. Inspired by â€Å"Rotoscoping†, an old time consuming animation technique that was being used in the early 1900`s, in which the animation would track m ovement frame to frame. In the field of entertainment Motion Capture is considered as the descendant of that same technique, which is still being used by some traditional animation studios to duplicate realistic motion from movie footage over to a cartoon characters. For centuries some of the motion capture technologies have been used in different ways, most known for its medical and military purposes. Originally it was examined by the Military to track head rotations of pilots by electromagnetic motion capture. Capturing motion could be done in few different ways. A lot of them use camera systems that produce digitized views of the performance, which afterwards is used to combine the location of the key points represented by one or more markers. Other way of capturing motion is being made by using electromagnetic fields or ultrasound to track a group of sensors. Also available is the mechanical system, which is based on the linked structures or the armatures that use potentiometers to identify the rotation of every link. Menache, A. (2011). Understanding motion capture for computer animation. Burlington, MA, Morgan Kaufmann Motion Capture input systems Prosthetic That is probably one of the first methods that have been used for capturing motion from various parts of the human anatomy. These methods include simple switching type of motion detection systems as well as complex tracking systems. If it wasn`t for the complex mechanical needs and the performance inhibiting qualities which are generally associated with such designs the latter type of prosthetic motion capture could be an ideal approach. Nonetheless, this method uses armatures which have to be attached all over the performers body. Afterwards they are being connected to each other by using a series of rotational and linear encoders. Once that process is complete all the encoders are connected to an interface that simultaneously reads all the encoders and prevents data loss. In the end through a set o f trigonometry functions the actual performer`s motion is being analyzed. (http://www.siggraph.org/education/materials/HyperGraph/animation/character_animation/motion_capture/motion_optical.htm) Acoustic This is a complex method that involves the use of audio receivers. Large amount of audio transmitters are strapped to performers body. Each receiver calculates the time that it takes for the sound to travel from each transmitter. In the 3D space the distance of the receivers is being measured to provide a point in the dimension. Normally the optical systems are occupied by occlusion problems which in that case is none existent and is considered as and advantage. (http://www.siggraph.org/education/materials/HyperGraph/animation/character_animation/motion_capture/motion_optical.htm) Magnetic This is one of the most used methods for performance capture. In that case it is used a centrally located transmitter, as well as large amount of receiver that are strapped on to various parts of the performers body. Once that is complete the receivers measure their spatial relationship to the transmitter. Every receiver is linked to an interface that can sync to prevent data skew. Each receiver then obtains the data stream which consists of 3D positions and orientations for each other. That data is usually applied to an inverse kinematics systems to an animated skeleton. The magnetic method shares the same advantage as the audio method, it lacks occlusion problems. (http://www.siggraph.org/education/materials/HyperGraph/animation/character_animation/motion_capture/motion_optical.htm) Electromagnetic Motion Capture is one of the more technical type of Motion Capture relying on transmitters and receivers to track movement. Optical Optical Motion Capture is another type of motion capture, it requires the actor or actresses to wear reflective sensors over a tight â€Å"Mocap Suit†. They would then proceed with their act an at that time several cameras will be tracking th e reflective pads. Recently, that type of motion capture has become quite popular. The advantage of that method is that it doesn`t require any sort of cables and the actor can perform freely. That system requires over three cameras, each of which is equipped with its own light so that it can illuminate the field of view for the specific camera. A frame buffer is being used that is connected and synchronized with each camera. The computer receives view from each camera in order to measure a 3D position of each marker.

Canadian Identity :: essays research papers fc

Throughout Canada’s relatively short existence we have created quite a reputation for ourselves. Our great nation is known for many things , and I am proud to say that most are positive. Does Canada have a strong national identity? Anyone can see the answer is yes. Just take a look at the facts. For example, we are renowned for our peacekeepers and no other country is considered more peaceful. Without a doubt this is the type of identity we should work to keep. The first thing we should examine is what exactly is meant by â€Å"strong national identity†. A very good example of strong national identity is the U.S.. I doubt there is a man on this planet who is not familiar with the U.S.. People immediately recognize their flag, and most people can tell you quite a bit about them. The same is true of Canada, and what do they know of Canada? In 1995 U.S. President Bill Clinton stated his view of Canada in a speech where he declared, â€Å"Canada has shown the world how to balance freedom with compassion and tradition with innovation, in your efforts to provide health care to all your citizens, to treat senior citizens with the dignity and respect they deserve...†(Canada Today 9). We were also rated first in the UN’s 1992 â€Å"Human Development Index† (9).   Ã‚  Ã‚  Ã‚  Ã‚  As I have already stated Canada is very well known for our many peacekeeping efforts. This is due to the many places our peacekeepers have been, or are at this very moment, such as Bosnia, East Timor and even Central Africa. These are just a very small portion of the places our peacekeepers are presently stationed. I am not even mentioning the dozens and dozens of other places they have been to. Our peacekeepers have helped save countless lives and Canada has gained relatively little in return, but Canada does it anyways, because it is the right thing to do.   Ã‚  Ã‚  Ã‚  Ã‚  Aside from our activities outside the country, we are also one of the best countries to live in. We have one of the top 5 life expectancies for both men and women. We also have the longest expected education according to the UN’s stats. These are just a few reasons why Canada is the greatest country.   Ã‚  Ã‚  Ã‚  Ã‚  Not only do we have a lot to offer Canadian citizens, here is a list of reasons to immigrate to Canada provided by KAM International:
