3D printer Lab Report Example | Topics and Well Written Essays - 250 words

3D printer - Lab Report Example There are several accessories required to use the equipment in the lab. An advanced slicing engine, the algorithm that directs a MakerBot Replicator, powers the machine. The materials used determine the product, but it is essential to understand the software and other computer applications that are required for the model before printing (3D Creation Lab). One also needs to select an appropriate polymer or business papers if one needs a durable prototype. The process for 3D printing is a lengthy process, but in the end, it turns digital designs into realism. It involves laying successive layers of materials using a computer, in an additive process that continues until one reaches the desired product in terms of geometry and shape. A computer aided design (CAD) package is used to design a model before the printing process (3D Creation Lab). After examining the design for manifold errors, one converts the model into thin layers, which designers tailor according to the type of printer. An inkjet printer head sets down material onto a powder bed in succession, through processes such as extrusion and

Investigation of temperature on catalase activity Essay Example for Free

Investigation of temperature on catalase activity Essay The aim of this experiment is to find out the effect of temperature on catalase or hydrogen peroxide. This will enable us to tell at what temperature hydrogen peroxide is most efficient. This (degradation) reaction will help us determine some of the catalases different attributes. HYPOTHESIS In this experiment it would be safe to hypothesise that no activity would take place at 1 to 20 degrees. It would be probable that a little activity would take place around 40 degrees. When the water gets to around 60+ the oxygen bubbles start to froth. It is almost certain that this will happen due to the behaviour of the atom. This means that the hotter the water gets the more active the water molecules become. Thus the colder the water gets the less active the water becomes. Another theory is that different things adapt according to their habitat. Therefore, catalase would be most active at around 37 degrees body temperature. This means that in this experiment catalase would be most active in the water bath that is at 40 degrees Celsius. METHOD Before the experiment could be started the following apparatus needed to be obtained: Cork Borer Water Baths at 3,20,40 and 60 degrees Celsius Potato Ruler Stopwatch Detergent Hydrogen Peroxide Now that all this apparatus has been obtained, it is possible to start the experiment. Eight test tubes will be required because the experiment is being done twice in each water bath. Use a marker pen to mark the specific temperature on the test tubes so as to make sure that there are no possible errors. Now place these test tubes in a test tube rack. Take the cork borer no. 4, and take a cylinder of potato using the cork borer. Do this until you have eight cylinders. If there are any cylinders that are uneven in size, then take the cylinder again using the cork borer. Now that you have good cylinders, cut them to equal length equal to 1.5cms. cubed. Once this has been done, put each potato cylinder in a test tube. Now it is almost time to start the experiment, so have a stop- watch at the ready. Pour 5cms cubed of hydrogen peroxide (H2O2) into each test tube. Now go to the first water bath that is 3 degrees Celsius and take a pipette and pour 10 drops of detergent into the first 2 test tubes (the test tubes that are labelled 3 degrees Celsius). Once you have done this, immediately start the stopwatch and simultaneously put the 2 tubes into the water bath. Repeat this process for the next 3 water baths. Although only 1 stopwatch has been used, the time will be fairly accurate since a delay has been created. When 5 minutes is up go to the first water bath with a ruler and measure the amount of froth on each test tube. RESULTS Experiment No.Temperature (oC)Height of Froth (cm)Average Height of Froth (cm) 133.33.15 2333.15 1203.43.5 2203.63.5 1406.56.0 2405.56.0 16032.95 2602.92.95 CONCLUSION In conclusion to this experiment, it is evident that catalase is most active at 40 degrees Celsius. There is a trend in a graph that shows the froth increases up towards 40 degrees Celsius and dips when reaching 60 degrees Celsius. It is not just a case of the Enzymes activity decreasing it becomes denatured shortly after it reaches its optimum level of activity. EVALUATION In this evaluation, the flaws and the limitations of this experiment will be outlined. The procedures in this experiment were very effective. Unlike many other experiments the control of the variables was without fault, because a machine was controlling them, i.e. the water bath. There were not many limitations of equipment, and the only way the equipment could have been improved would have been to have the experiment monitored by computer. All the sources of error in this experiment were with the non-variables. Firstly, there was no way of being sure that each potato was the exact same length or mass. A way of improving this would be using a guillotine-type device, meaning that the potatoes were at least the exact same length since  they were cut at equal angles all together. Another flaw is the amount of H2O2 poured into each separate test tube. This is cannot be improved upon unless done by machine. Other sources of error that could only have been improved upon by machine are height of froth, and amount of detergent. A major defect that could have affected the results is the timing. This is because of the delay system used. The only way that the delay system could have worked like clockwork is if it took the exact same time to measure froth as to pour detergent. There are two ways of improving this. The first is to make the experiment last longer. This would mean that it would not matter if there were a few seconds difference in the times, because no more froth could have been produced. The second is that if the experiment was timed separately for each bath.

Prejudice in The Merchant of Venice :: Free Merchant of Venice Essays

Prejudice in The Merchant of Venice It is my strong belief that the play, "The Merchant of Venice", should be taught in classes. If this play was banned from schools it would most certainly be a form of censorship. The play teaches us about prejudice, and why it is wrong. People would see how everyone was hurt at one time or another by a prejudice, whether it was the Christians making fun of Shylock or Shylock showing his prejudice to the Christian's. I imagine that anyone watching, listening or reading this play would see how everyone was hurt, and would learn of racism's faulty basis's for judging someone. Some people would have you think that the play itself is racist, and provides a forum in which racism can grow and become only a bigger problem. I think that this is a flawed way of looking at it. I see the play as a confrontation of a modern day problem which society still faces. Rather than providing a forum for racism to grow, the play provides a forum for anti-racism discussion, if all proper steps are taken. When I say if all proper steps are taken, I am referring to having this play taught by a teacher, who can explain the plays meaning in it's fullest so that the students do not miss any important points from it. Another point that may have been missed when the presentation was made to the school board to ban the material from being taught inside the school system was that everyone is bad in the play. The Christians portrayal was just as bad as the Jewish man, Shylock's portrayal. In fact I think that the play gave a worse portrayal of the Christian's because they ended up being the most evil, through taking away everything that Shylock had and making him become Christian. While Shylock did want to kill someone, the punishment invoked on him was even worse. As you can see, there are many reasons why "The Merchant of Venice" should be taught in classrooms. A. Whitney Griswold said in a speech (1952), "Books won't stay banned. They won't burn. Ideas won't go to jail.

The Womb: The New Scientific Frontier? :: Pregnancy Fetus Papers

The Womb: The New Scientific Frontier? In 1967 James Conniff, a reporter for the New York Times Magazine, wrote that the womb was the new frontier of science (Maynard-Moody, 1995). His article, and a smattering of other voices uncomfortable with fetal research, were a foreshadow of the great political and social controversy over the use of fetuses in scientific research. Prior to the Supreme Court's ruling in Roe vs. Wade in 1973, fetal research went on relatively peacefully without any protests from the public. After abortion was made legal by the Court's decision, the country was split between pro- and antiabortionists. While not their primary target, fetal research became another issue used by the antiabortionists to further their political interests. "Fetal research became a small skirmish in the larger battle over abortion" (Maynard-Moody, 1995). Representatives in government were sometimes elected based solely on their abortion position. The immense political pressure brought on by the antiabortionists caused otherw ise pro-research politicians to vote for bans on fetal research. A ban on federally-funded fetal research was put in place by the Reagan Administration and continued through Bush's years in office. A day after Clinton was inaugurated, he lifted this ban. The political and social controversy surrounding the use of fetuses has not died down or been resolved, however. No one doubts the value that fetal cells might have in the treatment or cure of many diseases, but the arguments on both sides of this issue deal with ethical considerations. The basic factor that informs both sides is how they define the rights of the fetus. On one side is the view that if the fetus is nonviable or is going to be aborted anyway, it is just tissue that should not go to waste. The other side of this issue are those that consider it immoral to use tissue from abortions. One proponent of this view is John Cardinal Krol who said, "If there is a more unspeakable crime than abortion itself, it is using the victims of abortion as living human guinea pigs" (Maynard-Moody, 1995). Steven Maynard-Moody, in his book The Dilemma of the Fetus, discusses the underlying tension that makes this and other medical advances such as gene therapy or human cloning so controversial in our society. He says that the underlying tension is "the friction between our addiction to progress and our fear that science erodes human values" (Maynard-Moody, 1995). He gives the example of the tragedy of the medieval Dr.

Free and Fair Election

Free and Fair Election The electoral system have to be fair and just and to ensure this, free and fair election will be held when the Parliament is dissolved or finish it’s sitting duration of 5 years. A free and fair election must be in orderly manner and it must not have Coup d’etat. Coup d’etat is meant by a sudden decisive exercise of force in politics . It is an alteration of an existing government by a small group that tend to create riots and chaos. The current Malaysia government believe that Bersih 2. 0 and 3. 0 is an attempted coup d’etat to topple the government – an allegation made by the Prime Minister himself.But the 8 demands from Bersih 2. 0 have no bias standing against any of the governmental parties in Malaysia. Basically they just wanted a clean and fair election, which is the fundamental element in the electoral system. Malaysia practices the simple plurality system which is also known as ‘first-past-the-post system. The h allmark of this system is that constituencies are single-member constituencies and a candidate with the largest vote wins the electoral district even if it does not constitute an absolute majority of the electors.Article 116 and 117 constitute that representatives at State and Federal level are divided into constituencies in accordance with the provisions contained in the Thirteenth Schedule. This system is following the Westminster post system which is also followed by UK and India. The MP who won the election does not usually equal to the majority of votes. They won the election by simple majority but not the entire popularity of the voters. The fundamental built on this system is that each voter is entitled to only one vote. Constituencies are approximately equal in population size so that it carries the same value.All constituencies are single-member constituencies so that there are as many electoral districts as there are seats in the elected chamber. Only one ballot is held an d the candidate obtaining the most votes is declared elected. Candidate with the largest vote wins. The advantages of the simple plurality system are that it produces a clear winner; it provides political stability; reduce the number of political parties represented in Parliament; enables stability in government and ensures easy passage of legislation through Parliament. Furthermore, it avours large groups and coalition and eliminates small parties, making it an easy tunnel for the legislation making to pass through. There is no perfection in everything, so does the political electoral system. One of the defects of first-past-the-post system is that it produces parliaments that are elected but not representative. Democratic legitimate is in doubt because the ascendancy of government population is usually below 50%. Voters who voted for unsuccessful candidates receive no representation in Parliament. In 1982, 60. 5% of the votes gave to the Barisan 85. 7% of the constituencies. In 20 04, 63. % of the ballots translated to 90. 41 seats in the Dewan Rakyat. These flaws can be minimized with the system of proportional representation where the parliamentary seats are given to the parties in proportion to the number of votes obtained by them. In single transferable vote system, a candidate is elected only if he obtains the quota of the vote cast. It is a multi-member constituency but each voter has only one vote and he is required to mark out his preference for different candidates. In the list system,each party is allowed to put up a list of candidates equal to the number of seats to be filled.The voter gives his vote to the whole list en bloc. There must have an honest and competent administration to run the election so that the election will be fair. The Election Commission must be fair. Article 114(2) of FC written that in appointing members of the Election Commission the YDPA shall have regard to the importance of securing an Election Commission which enjoys pub lic confidence. This implies that public confidence is essential and to gain the public trust, independent and fair Election Commission is a must.In Article 114(4)(b) and (c) also clearly stated that the YDPA shall by order remove from office any member of the Election Commission if such member engages in any paid office or employment outside the duties of his office or is a member of either House of Parliament or of the Legislative Assembly of a State. By staying away from the executive and legislative branch, it prevents the Election Commission from choosing side or bias towards any of the party in the election. Even their remuneration comes from consolidated fund as stated in Article 114(5) of Federal Constitution.This proves that the Election Commission is neutral from the government. Their duties are to conduct election, keep the election roll clean and constitutes boundary as listed. Mobilising organisations like political parties aided our country to envisage democracy. Non-p olitical associations and organisations like firms, industries, trade unions and religious organisations help to create and mobilize public opinion. This indicates that developed system of a political party is essential to ensure fair and free election. In Malaysia political parties are allowed but they must apply for registration under Societies Act.Nearly 34 political parties are registered with the Registrar of Societies. The ruling Barisan National is the world’s most enduring political coalition. Starting out as the Alliance since 1955, today it has 14 parties, 9 which won federal parliamentary seats. There are 20 registered opposition parties, 4 of which gained parliamentary representation. To achieve a free and fair election, candidates must apply the general rules of fair play. Equal chances should be given to each participating parties to conduct their election campaign.Election campaign could be conducted through media and spreading their propaganda. Shifting voters illegally, creating â€Å"phantom† voters, granting illegal immigrants citizenship and the right to vote, buying votes, handing out cash aid to vulnerable groups, and intimidating voters are crimes of election and must not be conducted in any way. The use of propaganda is limited in some countries by forbidding use of opinion polls, newspaper advertisement and house to house campaigns. Giving of free transport, food and bribes to the electorate is forbidden.But government after government gets around the law by promising or delivering â€Å"development aid† just before the election (Prof. Shad Saleem Faruqi, 2008). In Malaysia, under the Elections (Conduct of Elections) Regulations 1959-82, the period for election campaign has been progressively shortened from the period of 147 days to a minimum of 11 days. The conduct of the campaign is supposed to be fair and equal to each participating parties. But the Government’s ban on political processions on the alleged ground of security make the certain parties unable to reach the electorate and to mobilise public opinion.The short campaign period limits out the other parties to reach out to the electorate. The ownership and control of the mainstream print and electronic media by the Government or groups affiliated with the ruling coalition like TV3, Bernama and Berita Harian gives the Government an unfair advantage over its opponents. These issues need to be addressed and redressed. The right to speech, assembly and association are the essential pillars of a democratic set-up; to reach the goal of free and fair election. Speech, assembly and association are restrained considerably in Malaysia.Though Article 10(1) enshrines these freedoms, Articles 10(2), 10(4), 149 and 150 permit the Parliament to impose restrictions on the exercise of these freedoms on 14 constitutionally permissible grounds. A plethora of laws has been enacted under the authority of the Constitution to ensure that electoral z eal does not compromise race relations, national security and public order. As in during ordinary or election campaign, processions, public rallies and assemblies are not allowed except with a police permit under the Police Act. The recent case of Bersih 2. rally was an assembly that was not permitted by the Police Act, although their organization was legal and permitted. The root to achieve fair and free election results is through the votes. Malaysia uses the â€Å"One vote, one value† which is based on one cardinal principle- that constituencies should be approximately equal in population size so as to give reality to the principle of one person, one vote, one value. This principle is an offshoot of the rule of equality before the law. The weightage of the votes are differ based on geographical areas, basically categorized into rural and urban area.The Baker v Carr rules gives parliaments a primarily urban bias. For this reason many countries including Malaysia allow rural constituencies to be smaller in population size than urban electoral districts. â€Å"Rural† or â€Å"urban† are not defined in the Constitution and wide disparities in population exist from constituency to constituency. Population, geographical size and the urban-rural dichotomy seem to have exerted influence. Labuan, Putrajaya, Kelantan, Pahang, Perak, Sabah and Perlis are over-represented. Selangor, Kuala Lumpur, Johor and Terengganu are under-represented in the federal legislature.

Communication Essays - Nonverbal Communication, Romance, Free Essays

Communication Essays - Nonverbal Communication, Romance, Free Essays Communication Question 1 Option A Communication between two people sometimes is misinterpreted. One aspect of communication that makes it easy to distort the message being sent to a person is the use of nonverbal codes. Nonverbal codes are codes of communication consisting of symbols that are not words including nonword vocalizations.(P/N 73) The two categories I choose for this test are kinesics and paralinguistic features. Kinesics is the posture, movement, gestures, and facial expressions that are used to send a message. (P/N 73) One example of this is giving the finger to another person, which is showing only your middle finger to someone. This is socially accepted within the group of friends that I run around with, because it is saying, forget you I dont want to hear it, but nothing more is thought of it. It is used in a joking manner, if you are being serious then it is not the right situation to use it. If it is misinterpreted, or used in a serious manner, then it will most likely offend the person that it was directed to. At the same time you only want to give the finger to someone who you are friends with on a personal level. These rules are just a set standard, which are learned through observations. Paralinguistic features are the nonword sounds and nonword characteristics of language. (P/N 79) An example of this is when someone yawns. This is when someone is tired; the body does not function as well. Their circulation is not as good and the body is trying to get more air to the brain. It is socially accepted because it is something that can not be controlled. However, it is also considered rude to do when someone is talking to you because the impression that you are not listening is given to the speaker. In return, if done frequently enough the impression that you do not like the person can be given. This rule is learned from observation. It is important to be aware of the implicit rules for cultural/co-cultural nonverbal codes because if not known then you can easily offend people. The example of giving the finger to someone might mean something else in another country. It might mean nothing at all; in that case, people would not understand you. On the other hand, it also might mean something terrible mean, and then you would offend them. It is important to understand these rules so the signals that you are intending to send will not be misunderstood. Question 2 Option B The Sapir-Whorf Hypotheses states that you can only feel what you can explain in words. If you do not have the words to explain a feeling then you can not feel that feeling to the full extent. Someone who can explain it in words will have a more enriching experience. I personally disagree with this statement. I have to say that when you fall in love no one can explain it completely, but it does not take away from their experience because they can not explain it. My personal example of this would have to be of a church retreat that I went to four years in a row. It was the most wonderful thing that happened to me. The worshiping and the love that I felt with the people there is just indescribable. I do not feel that just because I could learn how to describe it that it would make my experience any better. The only thing it would allow me to express the feeling. This theory is not important to studying communication. Since what is actually stated is not true what good does it do. I feel that people who have a bigger vocabulary might be able to describe the situation better, which in turn means better communication. However, this is not what the hypothesis is stating. Question 3 In a relationship, there are stages that it will go through. While going through these stages, not every relationship will hit every stage, and in the relationship, some stages will occur more than others will. The three most important stages are intensifying, bonding, and differentiating. Intensifying is the stage where the two people where notice that they have a relationship and try to take it to a higher

To Kill a Mockingbird (Atticus essays

To Kill a Mockingbird (Atticus essays Although Atticus describes Mrs. Dubose as "the bravest person I ever knew", it is Atticus himself who is the real hero of the novel. Atticus is unlike most heroes, he is a humble, intelligent man who teaches his children that moral courage is far greater than being brave with a gun in your hand. Throughout the novel his character shows compassion and sympathy for the less fortunate, whether they be right or wrong. In a time in America where blacks were considered to be subhuman he has a black woman raising his children and defended an innocent black man,doing so with integrity and pride. Atticus Finch is a good lawyer, who believes in justice and the justice system. Atticus Finch would have been one of the few lawyers of his time who could honestly admit that he believes that the justice system should be colour blind. Through Scouts eyes we only get the smaller details of the Tom Robinson trial in the beginning, although her point of view also makes Atticus, her father, seem to us, as he would seem to her: a hero. In his closing statement Atticus stated a famous quote from a man admired by most the people in the court room and most importantly on the jury he said " Thomas Jefferson once said that all men are created equal .... we know that all men are not created equal in the sense some people would have us believe - some people are smarter than others, some people have more opportunity because they are born with it.... But there is one place in this country in which all men are created equal - there is one human institution that makes a pauper the equal of a Rockefeller, the stupid man an equal of Einstein and the ignorant man the equal of any college president. This institution, gentlemen, is a court .... in our courts all men are created equal" (pg. 209). Atticus is a very intelligent and well educated man. This is evident his personal beliefs and high moral standards are told to his adolescent children as advice. His civ ...

Alexander pharaoh of egypt Essay Example | Topics and Well Written Essays - 750 words

Alexander pharaoh of egypt - Essay Example For thirty years, he established one of the biggest empires of the prehistoric world. The empire overextended from Egypt to Greece and also into the north western part of India. In fact, Alexander was never defeated in any wars and to date he is deliberated as one of the supreme prosperous military commanding officers. Further, in his crusade that was contrary to the mighty Persian Empire of Darius III, Alexander the great spent some months in Egypt. Regardless of the hostilities Alexander received from the Spartans, he emerged victoriously against Persia. The first war that he emerged victoriously was the battle of Granicus that was battling in the year 334 BC in present-day Turkey, and not so far from the prehistoric town of Troy. He was considered to have fought twenty thousand Persian horsemen and foot soldiers of the same number. After that, he moved to the western coast of Turkey, taking towns and trying to refute Persian navy of stations (Thomas, 7). The second major fight that Alexander won was the most significant of all fights. The war was known as the battle of Issus, which occurred in the year 334 BC, in southern Turkey at a prehistoric town known as Issus that was near to the present-day Syria. The Battle of Issus was directed by Darius III himself and Arrian estimates that Darius had a team of six hundred thousand troops. Due to this, Alexander was reluctant to go into a fight, and this made Darius think that it was a sign of nervousness. One attendant after another encouraged Darius and thus made him announce that with his Calvary, he will crush the Macedonian military. Therefore, he started to hunt Alexander but this at first seemed like he was overwhelming Alexander’s side. This changed after Alexander presented the Persian king with a battle, and the Persians could no longer apply their higher numbers well. In addition, Arrian wrote that the Darius leftward group ran scared immediately they started battling. This made the

2 contract law assignments Essay Example | Topics and Well Written Essays - 3750 words

2 contract law assignments - Essay Example However, that right would have arisen by virtue of common law principles rather than statutory law as contained in the Contracts (Rights of Third Parties) Act 1999. Owen Fox explains that ‘for many years, the doctrine of privity of contract was a fundamental feature of English law, meaning that it was only the parties to a contract who could rely upon or enforce the terms of that contract. The consequence of this was that if a third party suffered a loss because the contracting parties failed to fulfil their obligations to each other, then the third party had no recourse under the contract.’2 This is the background against which Sarah Jones Development’s claim for damages against Archibald must be examined. There were and are exceptions to the privity of contract rule. One exception is to be found in circumstances where a collateral contract exists. For example when there is a contract between two parties one of the parties thereto may have a collateral contract with a third party in respect of the same matters contained in the primary contract. Shanklin Pier v Detal Products [1951] 854 provides a good example. In this case the plaintiff hired a contractor for the purpose of painting a pier. The painting contractor was instructed to purchase the paint from the defendants. The defendants informed the plaintiffs that the paint would last for seven years when in fact it only lasted for three months. As a result the plaintiff took the defendants to court despite the absence of a contract between them and defendants. 3 The court ruled that the plaintiffs could sue the defendants for damages on the basis of a collateral contract. The plaintiff had provided consideration in exchange for the defendants’ assurance of the quality of the paint by indorsing a contract with the painting contractor which specifically required that they purchase the defendants’ paint.4 The general tone of judicial findings was that there must be an intention to form a

Art History Essay Example | Topics and Well Written Essays - 1250 words

Art History - Essay Example Each of the pieces shows a specific movement toward this new era, while providing different aspects outside of the Gothic style with the pieces. The first way in which the pieces move outside of the Gothic style and into the Renaissance is the canvas that is used within each piece. For instance, â€Å"L’Annonciation† and â€Å"The Unicorn Tapestries† both use several different frames to depict a specific setting and story. While some of this is more Gothic in nature, it was a known attribute of the Renaissance era to combine the several panels and to create a movement through these several frameworks to create a different ideal. The space, according to the Gothic ideal is one that represented â€Å"freedom, movement and sense of relationship† (Stockstad, 537). Instead of a sense of complete freedom within each of these canvas,’ there is a defined frame that each carries to tell a story and to create a specific definition. The canvas that is used within each then moves into the specific attributes and characteristics that each carries. This can first be seen with the ornamentation that is a part of the Gothic era and the Renaissance period. In the Gothic style, ornamentation was one of the central aspects to the different paintings, sculptures and architecture in the art work. This was defined as elegant in nature and was refined. The use of geometrical spacing to create the ornamentation was one of the central aspects of the Gothic era. However, the Renaissance began to rebel against this and to create more defined paintings, without the use of as much ornamentation or architecture in the background. Each of the pieces that are seen has more of the Renaissance style then the Gothic approach to the ornamentation used. The picture, â€Å"L Annonciation† is one that shows this concept. While there is ornamentation in some of the background items and architecture

Communism And Nonalienated Labor is best Essay Example | Topics and Well Written Essays - 1500 words

Communism And Nonalienated Labor is best - Essay Example According to communism, which was highly promoted by Karl Marx, the means of production should be controlled by the state (the state owns everything). Mass production implies producing large amounts of commodities at a cheaper cost. Alienation simply means to segregate things that naturally occur or belong together. An alienated labor implies a worker being separated from his/her products. In division of labor, workers specialize to perform specific tasks assigned to them in production process. Karl Marx (1818-1883), argues that communism and non-alienated labor is the best practice in any society based on the arguments discussed below. Marx in his theory found that there are two groups of people in the capitalist society. On one side, there are the Bourgeois class who owns means of production and wealth. On the other side, there are the Proletarians, who are the working class. The Bourgeois exploit the proletarians. He further argues that the bourgeoisie’s agglomeration of population, centralization of means of production and of wealth in the hands of a few, is not a good practice to the society. It is against the social justice in the society. That, according to Karl Marx, leads to centralization of political power. Regions in a given society tend to be independent though loosely attached. They have different political interest, laws and taxation policies. After centralization, they suddenly become one with a common law, one frontier, one class-interest and similar costs. It is unfair for such a society to exist, given the gap between the upper class (the rich) and the lower class (the poor). Laws governing such a society especially taxation laws and policies might not reflect true scenario on the ground. The bourgeoisie takes advantage of the proletarians since they can easily influence them using their wealth or resources. The working class

Art History - Essay Example Each of the pieces shows a specific movement toward this new era, while providing different aspects outside of the Gothic style with the pieces. The first way in which the pieces move outside of the Gothic style and into the Renaissance is the canvas that is used within each piece. For instance, â€Å"L’Annonciation† and â€Å"The Unicorn Tapestries† both use several different frames to depict a specific setting and story. While some of this is more Gothic in nature, it was a known attribute of the Renaissance era to combine the several panels and to create a movement through these several frameworks to create a different ideal. The space, according to the Gothic ideal is one that represented â€Å"freedom, movement and sense of relationship† (Stockstad, 537). Instead of a sense of complete freedom within each of these canvas,’ there is a defined frame that each carries to tell a story and to create a specific definition. The canvas that is used within each then moves into the specific attributes and characteristics that each carries. This can first be seen with the ornamentation that is a part of the Gothic era and the Renaissance period. In the Gothic style, ornamentation was one of the central aspects to the different paintings, sculptures and architecture in the art work. This was defined as elegant in nature and was refined. The use of geometrical spacing to create the ornamentation was one of the central aspects of the Gothic era. However, the Renaissance began to rebel against this and to create more defined paintings, without the use of as much ornamentation or architecture in the background. Each of the pieces that are seen has more of the Renaissance style then the Gothic approach to the ornamentation used. The picture, â€Å"L Annonciation† is one that shows this concept. While there is ornamentation in some of the background items and architecture

BIOLOGY - Essay Example An outer membrane which forms the outer covering of the organelle and inner membrane which is twisted n folds to form specific structure called Cistae. There are granules attached in the inner folds of cistae and the inside of a mitochondrial is filled with mitochondrial matrix. The main function of mitochondria is to produce energy for the cell in the form of ATP hence the name ‘power house of the cell’. Ans3. Centrifuge is process through which we can obtain different cell organelles. The process works in a way that when a solution containing cells is centrifuged, the supernatant fluid containing our required cell organelles separates out on the surface which is then collected and observed under the microscope to study required cell organelle. Ans4. Hemoglobin is present in red blood cells and is a necessary component for living things to survive. Hemoglobin’s main function is transport of oxygen. When deoxygenated blood goes through the lungs, the hemoglobin in RBCs attracts oxygen towards it. Oxygen binds with hemoglobin in the blood cells and is carried out to the body tissues where it is released from the hemoglobin and blood once again goes to lungs for oxygenation. Ans5. The main mechanisms of transport through cell membrane are 1) Diffusion 2) Active transport and 3) passive transport. Diffusion is the simple moving of molecules through the cell membrane across a concentration gradient. Active transport occurs when a molecule is supposed to be transported against the concentration gradient. Active transport takes place with the help of specific carriers that carry our required molecules against the concentration gradient through specific channels and this process requires energy. Passive transport occurs when a molecules uses another channel to move across the cell membrane. Ans7. DNA consists of two ribose sugar strands which are joined by nucleic acids Adenine, Guanine, Cytosine, Thymine. These bases form the inner

Imagining My Future Essay Example for Free

Imagining My Future Essay My hand flies to my heart, the other to Matthew’s hand. I startle awake from an endless nightmare. Luckily, I haven’t awakened my sleeping husband, who I must say sleeps like a rock. I stretch out and sit up, the covers pooling around my waist. The moonlight continues to shine into our room from the balcony. I give Matthew a quick kiss on his hand and slowly crawl out of bed into the depths of our house. I wander the empty hallways of this home Matthew and I have built. Pictures line the wall from our wedding, to the birth of our three wonderful children, Braden, Katarina and Adam. I couldn’t imagine any better life. As my hand skims the wall, my feet sink into the plush purple carpet that lines the hall. I touch the cold metal of my first son’s door knob and hesitantly open the door. Braden is twelve-years-old, and as athletic as his father. The first thing he learned to say was â€Å"Dada† and knew how to skate before he could walk. Hockey must be in his genes – he’s the captain of his Pee Wee B hockey team. He has a great future set in front of him. I tip-toe over to his queen size bed covered with blue sheets. Braden takes after his father in looks as well. His eyes are the rich color of the sky and grass combined; his hair a dark chestnut brown; a smile that is so perfect, he didn’t need braces. As I stroke his hair and pull the covers up, I remember the first time I dropped him off at school and I imagine how he’ll deal with going to a new school next year since its seventh grade. I turn off the music he plays every night to help him fall asleep, and exit his room as quiet as I entered. Katarina is only a year younger than her brother. She’s only eleven and is as independent as a teenager. She’s sprawled out on her queen size bed covered with bright colors that swirl around. I watch her breathing, a slow rhythm of ease as she dreams ever so peacefully. She takes after me, which I’m thankful for. Her eyes are a rich green, her hair a bright blonde, but Kat was born with teeth like her great-grandmother. She’s almost to the ripe age to get braces. I hope she won’t get teased when she gets them; it’s a grave fear of mine. Kat is always striving to be her unique self, and doesn’t exactly care what others think of her. Her fearlessness is something most other girls her age crave for. She’s a bookworm, just like her mother as well. Matthew and I brought her skating multiple times, but she didn’t really get the same sensation her momma felt as a figure skater. Instead, she’s a dancer – hip-hop and ballet – and she’s extremely gifted. Where she received her gracefulness on feet is something I question myself with everyday. She’s my angel, her father’s little girl, and her brothers’ best friend. I glance over to her window which is right above her bed. The moonlight casts a light upon her drooling face and I manage to hold back a giggle. I wonder how many hearts Kat will break when she enters the scary and dreaded place of high school. My littlest boy, Adam, sleeps the farthest away from his parents. He has the intelligence of Einstein and is constantly questioning everything. He isn’t big into the high-contact sport as his older brother, but is enjoying music quite much as well as tennis. Adam is eight, and loves his guitar. He plucks the strings night and day. His looks are that of mine and Matthew’s. As he sleeps, he snores a bit and fidgets, but the stuffed tiger his grandmother gave him is tucked safely away in his arms. Right now, Adam wants to be a rock star. I only hope he achieves the dream he decides on. His clothes are scatter around his floor and being as restless as I am, I can’t help but not pick them up. CD’s of oldies line shelf after shelf. I watch him move and he silently calls out for â€Å"Grandma.† Grandma Fern passed away few months ago and little Adam was her absolute favorite. When Adam found out about her death, he was devastated. He took up a vow of silence and wouldn’t come out of his room. Finally, Matthew and I were able to soothe him out to talk to us. He’s been back to his talkative self ever since. I close the door and hear the â€Å"click† of the door. I wander back up to my room, and dance to the balcony. I flop into the overstuffed red love seat Matthew and I placed outside. In the distance, I can see a glimmer of the soft lake that is only minutes away from my home. I cross my legs and sigh to myself. â€Å"Well hello there. Didn’t you ever learn to close the door?† a deep, rough voice says. I quickly whip my head around to see the man I call my husband. â€Å"Oh, dear I’m so sorry! I was caught up in how beautiful the night sky looked. I didn’t even think about the door.† I say hastily. â€Å"Well, I’m glad you forgot. You can’t keep this to yourself, you know.† Matthew says as he joins me. I’ve known him since I was a junior in high school and I’ve been infatuated with him ever since. His face is turned toward the night sky, and I can’t help but wonder how this fascinating creature is with me. Matthew has been playing hockey ever since the age of five, and has a knack at it. He played for the Fighting Sioux in college, and was moved up to the professional league when the Washington Capitals signed him to their roster. He was ecstatic about the offer. My children and I can’t go and stay with him i n Washington State, but we go to every game we can. He’s my children’s hero, and my own to love. I place a single hand on his cheek, an act I’ve always done towards him. â€Å"It’s almost morning wife. What are you going to make for breakfast?† he teasingly asks me. He knows whatever I cook, he has to help with. â€Å"Well, I was thinking some bacon, maybe an omelet. Unless you prefer something more five star.† I instantly challenge him. He picks me up and throws me over his shoulder as if I was as light as a feather. He lays me on the bed and suddenly we are in a game of chasing each other around the bedroom. He never ceases to amaze me. Of course, Matthew lets me win and we stroll downstairs to the kitchen, starting up the coffee, and planning out what to feed our children.

Comparison of different modulation technique

Comparison of different modulation technique 1. INTRODUCTION 1.1 Modulation is the process of varying one waveform in relation to another waveform. In telecommunications, modulation is used to convey a message, or a musician may modulate the tone from a musical instrument by varying its volume, timing and pitch. Often a high-frequency sinusoid waveform is used as carrier signal to convey a lower frequency signal. The three key parameters of a sine wave are its amplitude (volume), its phase (timing) and its frequency (pitch), all of which can be modified in accordance with a low frequency information signal to obtain the modulated signal. A device that performs modulation is known as a modulator and a device that performs the inverse operation of modulation is known as a demodulator (sometimes detector or demod). 1.2 TWO TYPES OF MODULATION A) Analog modulation B) Digital modulation Here we discuss analog modulation techniques. 2. AMPLITUDE MODULATION Amplitude modulation (AM) is a technique used in electronic communication, most commonly for transmitting information via a radio carrier wave. AM works by varying the strength of the transmitted signal in relation to the information being sent. For example, changes in the signal strength can be used to reflect the sounds to be reproduced by a speaker, or to specify the light intensity of television pixels. (Contrast this with frequency modulation, also commonly used for sound transmissions, in which the frequency is varied; and phase modulation, often used in remote controls, in which the phase is varied). 2.1 TYPES OF AMPLITUDE MODULATION As originally developed for the electric telephone, amplitude modulation was used to add audio information to the low-powered direct current flowing from a telephone transmitter to a receiver. As a simplified explanation, at the transmitting end, a telephone microphone was used to vary the strength of the transmitted current, according to the frequency and loudness of the sounds received. Then, at the receiving end of the telephone line, the transmitted electrical current affected an electromagnet, which strengthened and weakened in response to the strength of the current. In turn, the electromagnet produced vibrations in the receiver diaphragm, thus closely reproducing the frequency and loudness of the sounds originally heard at the transmitter. In contrast to the telephone, in radio communication what is modulated is a continuous wave radio signal (carrier wave) produced by a radio transmitter. In its basic form, amplitude modulation produces a signal with power concentrated at the carrier frequency and in two adjacent sidebands. This process is known as heterodyning. Each sideband is equal in bandwidth to that of the modulating signal and is a mirror image of the other. Amplitude modulation that results in two sidebands and a carrier is often called double sideband amplitude modulation (DSB-AM). Amplitude modulation is inefficient in terms of power usage and much of it is wasted. At least two-thirds of the power is concentrated in the carrier signal, which carries no useful information (beyond the fact that a signal is present); the remaining power is split between two identical sidebands, though only one of these is needed since they contain identical information. To increase transmitter efficiency, the carrier can be removed (suppressed) from the AM signal. This produces a reduced-carrier transmission or double-sideband suppressed-carrier (DSBSC) signal. A suppressed-carrier amplitude modulation scheme is three times more power-efficient than traditional DSB-AM. If the carrier is only partially suppressed, a double-sideband reduced-carrier (DSBRC) signal results. DSBSC and DSBRC signals need their carrier to be regenerated (by a beat frequency oscillator, for instance) to be demodulated using conventional techniques. Even greater efficiency is achieved—at the expense of increased transmitter and receiver complexity—by completely suppressing both the carrier and one of the sidebands. This is single-sideband modulation, widely used in amateur radio due to its efficient use of both power and bandwidth. A) DSB-FC In radio communications, a sideband is a band of frequencies higher than or lower than the carrier frequency, containing power as a result of the modulation process. The sidebands consist of all the Fourier components of the modulated signal except the carrier. All forms of modulation produce sidebands. Amplitude modulation of a carrier wave normally results in two mirror-image sidebands. The signal components above the carrier frequency constitute the upper sideband (USB) and those below the carrier frequency constitute the lower sideband (LSB). In conventional AM transmission, the carrier and both sidebands are present, sometimes called double sideband amplitude modulation (DSB-AM). In some forms of AM the carrier may be removed, producing double sideband with suppressed carrier (DSB-SC). An example is the stereophonic difference (L-R) information transmitted in FM stereo broadcasting on a 38kHz subcarrier. The receiver locally regenerates the subcarrier by doubling a special 19kHz pilot tone, but in other DSB-SC systems the carrier may be regenerated directly from the sidebands by a Costas loop or squaring loop. This is common in digital transmission systems such as BPSK where the signal is continually present. B) SSB-SC Single-sideband modulation (SSB) is a refinement of amplitude modulation that more efficiently uses electrical power and bandwidth. Amplitude modulation produces a modulated output signal that has twice the bandwidth of the original baseband signal. Single-sideband modulation avoids this bandwidth doubling, and the power wasted on a carrier, at the cost of somewhat increased device complexity. C) SUPPERESED CARRIER Reduced-carrier transmission is an amplitude modulation (AM) transmission in which the carrier wave level is reduced to reduce wasted electrical power. Suppressed-carrier transmission is a special case in which the carrier level is reduced below that required for demodulation by a normal receiver. Reduction of the carrier level permits higher power levels in the sidebands than would be possible with conventional AM transmission. Carrier power must be restored by the receiving station to permit demodulation, usually by means of a beat frequency oscillator (BFO). Failure of the BFO to match the original carrier frequency when receiving such a signal will cause a heterodyne. Suppressed carriers are often used for single sideband (SSB) transmissions, such as for amateur radio on shortwave. That system is referred to in full as SSB suppressed carrier (SSBSC) or (SSB-SC). International broadcasters agreed in 1985 to also use SSBSC entirely by 2015, though IBOC and IBAC digital radio (namely Digital Radio Mondiale) seems likely to make this irrelevant. D) VSB A vestigial sideband (in radio communication) is a sideband that has been only partly cut off or suppressed. Television broadcasts (in analog video formats) use this method if the video is transmitted in AM, due to the large bandwidth used. It may also be used in digital transmission, such as the ATSC standardized 8-VSB. The Milgo 4400/48 modem (circa 1967) used vestigial sideband and phase-shift keying to provide 4800-bit/s transmission over a 1600 Hz channel. E) QAM Quadrature amplitude modulation (QAM) is both an analog and a digital modulation scheme. It conveys two analog message signals, or two digital bit streams, by changing (modulating) the amplitudes of two carrier waves, using the amplitude-shift keying (ASK) digital modulation scheme or amplitude modulation (AM) analog modulation scheme. These two waves, usually sinusoids, are out of phase with each other by 90Â ° and are thus called quadrature carriers or quadrature components — hence the name of the scheme. The modulated waves are summed, and the resulting waveform is a combination of both phase-shift keying (PSK) and amplitude-shift keying, or in the analog case of phase modulation (PM) and amplitude modulation. In the digital QAM case, a finite number of at least two phases, and at least two amplitudes are used. PSK modulators are often designed using the QAM principle, but are not considered as QAM since the amplitude of the modulated carrier signal is constant. 3) FREQUENCY MODULATION frequency modulation (FM) conveys information over a carrier wave by varying its frequency (contrast this with amplitude modulation, in which the amplitude of the carrier is varied while its frequency remains constant). In analog applications, the instantaneous frequency of the carrier is directly proportional to the instantaneous value of the input signal. Digital data can be sent by shifting the carriers frequency among a set of discrete values, a technique known as frequency-shift keying. CARSONS RULE A rule of thumb, Carsons rule states that nearly all (~98%) of the power of a frequency-modulated signal lies within a bandwidth of where , as defined above, is the peak deviation of the instantaneous frequency from the center carrier frequency . Normal signal Modulated signal 4) PHASE MODULATION Phase modulation (PM) is a form of modulation that represents information as variations in the instantaneous phase of a carrier wave. Unlike its more popular counterpart, frequency modulation (FM), PM is not very widely used. This is because it tends to require more complex receiving hardware and there can be ambiguity problems in determining whether, for example, the signal has changed phase by +180Â ° or -180Â °. CARSONS RULE Suppose that the signal to be sent (called the modulating or message signal) is m(t) and the carrier onto which the signal is to be modulated is Annotated: carrier(time) = (carrier amplitude)sin(carrier frequencytime + phase shift) This make the modulated signal This shows how m(t) modulates the phase the greater m(t) is at a point in time, the greater the phase shift of the modulated signal at that point. It can also be viewed as a change of the frequency of the carrier signal, and phase modulation can thus be considered a special case of FM in which the carrier frequency modulation is given by the time derivative of the phase modulation. The spectral behaviour of phase modulation is difficult to derive, but the mathematics reveals that there are two regions of particular interest: For small amplitude signals, PM is similar to amplitude modulation (AM) and exhibits its unfortunate doubling of baseband bandwidth and poor efficiency. For a single large sinusoidal signal, PM is similar to FM, and its bandwidth is approximately, where fM = ωm / 2Ï€ and h is the modulation index defined below. This is also known as Carsons Rule for PM 5) SPACE MODULATION Space modulation is a radio Amplitude Modulation technique used in Instrument Landing Systems that incorporates the use of multiple antennas fed with various radio frequency powers and phases to create different depths of modulation within various volumes of three-dimensional airspace. This modulation method differs from internal modulation methods inside most other radio transmitters in that the phases and powers of the two individual signals mix within airspace, rather than in a modulator.

Inside Gates versus Out of Gates :: science

Inside Gates versus Out of Gates Turkey as an III World Society shows rapid urbanization process without industrialization which causes some problems in housing situation. In postwar period USA gave martial aid to Turkey, in order to provide to Europe agricultural needs, so there appears jobless villagers and sharecroppers because of changes in agricultural sector in terms of providing surplus by tractors namely by less human labor. So migration to big cities was emerged which is the reason for squatter settlements existence. On the other hand globalization plays a role in suburban development which is the upper-class people’s choice for leaving heterogeneous environment in city centers that causes to emerge new suburban homogeneous settlements as gated communities. Firstly, formation of squatter settlements implies ‘temporariness’ and the term ‘gecekondu’ refer building in one night. People build their gecekondus with having rising expectations for their future because they don’t have pessimistic feelings although they live in slums in the lack of even electricity. Gecekondu people are negatively labeled (stigmatized) as ‘peasants in the city’, uneducated, uncivilized, uncultured, backwards. They are also called as ‘varo ºÃ¢â‚¬â„¢, which is a sign of subordination and exclusion of these kinds of people. (Kiziltan, 2004) They survive in urban life by the help of democratic parties because they have high voting potential, which is populism as a political aspect, and also they provide cheap labor as their second survival factor in economic dimension. Gecekondu amnesty/pardoning become possible as gecekondu people play a role in production-having cheap labor potential and also in consumption by buying products which urban people use, in order to show that they can adapt to the urban life. According to Mass Society Theory, when individuals hardly connect to society they become members of social movements and mobilize against system. Besides this theory, second generation migrants are relatively deprived and fail to adapt in urban life so they display radical politic actions, try to challenge status quo, mobilize against advantaged groups. At the beginning squatters have only use value but after this value begin to turn into exchange value, so gecekondu people start to be stigmatized as ‘undeserved rich’, the villagers want to migrate to city to benefit from this exchanged value and other urban life’ social institutions(health services, education†¦etc) so there exits social mobility towards cities. Also, there is another factor which causes social mobility in squatters; squatters are heterogeneous environments which consist of people from different geographical background, so it is possible to expect high social mobility in these settlements.

A Turkish Student and the Board of Regents :: Argumentative Persuasive Essays

A Turkish Student and the Board of Regents In what ways can Iowa State University be improved? Responses to this question could vary widely depending on the background of the subject being interviewed. Perhaps an international student might suggest a new club or organization designed to acclimate foreign students to life on campus. However, John Couch, an international student from Turkey, had a much more unique response. Having a wide variety of friends isn't a large concern of his. He is more concerned with how the university is being run and the different boards and comities, in a particular the Board of Regents. John's opinion is that the Board of Regents isn't hearing the concerns of the students. In fact, they appear to be concerned less with the needs of the students and more concerned with the issues of funding. It is very unfortunate that the budget of the university has been cut, but the Board must still attempt to maintain a good relationship with the student body. The quality of education at Iowa State has suffered because of these budget cuts, and the Board has not posted any viable methods to attempt to replenish any of those lost dollars. When asked if he had any suggestions for going about this daunting task, John was unsure. There is definitely a need for more support to aid research, building renovations, and to allow for more teachers, reducing overall class sizes. John's opinion was influenced by his initial experiences at Iowa State. John spent two years in Iowa attending high school before choosing Iowa State. Even though when he graduated his family was still far away in Istanbul, Turkey, John was ready for college. He didn't know if he would fit in or if the other people would make fun of him, he just knew he was going to have fun and learn. John had heard about an organization called a fraternity and thought it sounded interesting. He would eventually join the university's chapter of Sigma Alpha Epsilon and would meet many new people.

Dog Breeding and Society Essay

Dogs are known to be man’s best friend. Cliche as it may sound like, dogs have proven continually over the centuries since they were first domesticated, just how helpful they can be in human lives. From being mere allies on the hunting grounds during the Neolithic period to adored and prized pets of families, dogs have been trained to take on more and more roles in human society. The domestication and subsequent breeding of dogs began with their ancestors the wolves. During the Paleolithic and Neolithic periods of human history, both man and wolves shared the same objective of hunting and gathering food, as well as the same enemy, the big cats. (Kreiner 4) Perhaps the humans at that time realized the benefits of having canines on their team in hunting and tracking prey that they began capturing wolf cubs and treating them as pets to be raised as hunters. (â€Å"Dogs and People: The History and Psychology of a Relationship†) With the evolution of dogs into many different breeds, people have also come to realize that not all dogs are the same and that is not just in reference to their physical appearance. In terms of utility, some dogs proved to be better suited to specific jobs like hunting and herding. Similarly, an appreciation for the physical and temperamental qualities of different dogs started taking root. From being mere canine companions, dogs started to be bred to fulfill specific duties. Dog breeding started to be a quest to find and develop the perfect specimen of dog breeds according to utility and genetics. HISTORY OF DOG BREEDING Since humans first started noticing the high trainability and utility of dogs, dogs have started to be bred for special purposes. These include hunting and retrieval of game, military and police service, guides for the blind, and erstwhile companions. (â€Å"Dog†) Dog breeding also finds its roots in the 19th century. Dog breeders believed that the public placed a premium on dogs of a specific size, color, physical, and temperamental qualities. This was proven true when the demand for â€Å"quality† puppies from dog breeders rose from purchases made by people seeking canine companionship or those who needed dogs for herding and hunting. Today the â€Å"elite† and prime examples of different dog breeds can often be seen show cased and recognized in Kennel clubs and dog shows held both nationally and internationally. The year 1859 saw the first dog show in Newcastle, England where judges focused mainly on working dogs and their skills rather than appearance. Dogs of different breeds paraded on floors sprinkled with sawdust and the judging was done only by three men. Today, the American Kennel Club (AKC) is one of the largest of such organizations concerned with recognizing exemplary specimens and abilities of registered dog breeds. Various competitions for dogs measuring their performance level at different skills are done on mostly weekend events. The competitions range from criteria based on different types of dogs or skills such as tracking and following commands. (Baldwin, and Norris 1) â€Å"There are three types of competition–conformation, obedience, and agility. The agility ring is the one many people are familiar with, where dogs go through various exercises and around obstacles,† says Adrian Woodfork, a licensed AKC judge†(Stokely 175) The conformation competition is said to be targeted at challenging breeders to improve the quality of purebred dogs through extra careful selection of breeding specimens as well as faithful recording of bloodlines, temperament and hereditary traits. (Stokely 175) Every year the AKC publishes a â€Å"point scale† that lists the number of awards available at each show based on the number of specific breeds involved in the show. Some actually view these competitions as perfect opportunities to learn more about different breeds particularly if there are contemplating buying a dog. THE NEW CAREER DOGS: Dogs bred and trained for specific jobs or purposes In addition to the traditional breeder who turns out show quality or traditional working dogs for either altruism or profit, there is another kind of breeder who caters to a market that requires highly intelligent and even-tempered dogs for modern purposes. Breeding Racing Dogs Kennel owner Maria Beck (Clarke, Wright, and Jones 250) is the owner of the Lightning Ridge Kennel in Kansas City, Kansas. It is from here that she not only breeds and trains champion greyhounds, but is the only known African American woman kennel owner in the business. Of greyhounds, she shares: â€Å"The animals are so graceful. The excitement of seeing them race took my heart and I realized that it was what I wanted to do. † Breeding Police or Military Dogs Dogs also contributed greatly to their human counterparts during wartime. In World War II, the American Kennel Club and a group called â€Å"Dogs for Defense† got together some quality dogs for donation to the Quartermaster corps. German Shepherds, Belgian Sheep Dogs, Doberman Pinschers, Farm Collies and Giant Schnauzers were trained in the new K-9 Corps between 1942 and 1945. These dogs would later end up saving the lives of thousands of men in combat by acting as sentries, â€Å"partners† and friends to the military or civilian guard on patrol as well as being scouts, messengers and mine-detection dogs. (â€Å"Dogs and People: The History and Psychology of a Relationship†) The K-9 program remains in place up to present time with dogs employed in police work of drug and bomb detection as well as search and recovery. â€Å"We look for high-energy dogs that have a high fetch drive, mostly bird dogs, like labradors and golden retrievers,† says Steven Buzzard of the West Virginia Division of Corrections (Clayton 64). Breeding seeing eye dogs The high trainability of certain dog breeds have also made them suitable for other jobs outside of the military and police force. Helen Docherty (â€Å"PUPPY LOVE; Ena Will† 30) is just one of the volunteer â€Å"walkers† who work with dogs at the Guide Dog for the Blind Association in the United Kingdom. Dogs like German shepherds, Labrador retrievers and Golden retrievers in addition to the occasional Boxer and mixed breeds are trained to guide the blind and keep them company. Helen describes her experience as: â€Å"You just have to remember that this dog came for a purpose and it will go on to do what it has been trained to do. The comforting thing is at least you’ve played a part in preparing the dog for the fabulous job in life it is meant for, with a blind person. † Breeding for purebreds Purebred dogs (â€Å"Dog†) are the products of â€Å"inbreeding† or â€Å"line breeding† which just keeps dog mating within just one family bloodline. Inbreeding means that bitches are mated with litter-mates, while line bred dogs are those that are the product or mating between a bitch and its close cousins, grand sire, and so on. These dogs are usually bred to conform to the standards of a certain breed and whose bloodline and lineage (also called pedigree) has been recorded for a prescribed period of time. Kennel Clubs usually keep track of the lineage of registered individual purebreds in order to preserve breed standards. Breeding aimed to diversify gene pool. Some breeders focus mainly on the appearance of their dogs without much regard for its pedigree. Mating dogs that are unrelated to each other through assortative mating, breeders try to solidify positive traits. This is also done when a breeder tries to acquire a lacking trait for his stock by mating one of his dogs with another who displays the desirable trait. Breeding hunting dogs There are also breeders who cater to buyers who need dogs for more specific and utilitarian purposes. Hunting and retrieval dogs are just one of the specialized breeds that enjoy a â€Å"niche† market. So does sporting dogs such as the retrievers, pointers, spaniels and setters. These dogs are especially useful for their ability to track air scents. Ground scent hunters belong to the hound group made up of beagles, foxhounds and bloodhounds. Olden England saw a great demand for this particular kind of breed for their fox hunts and point to point chases. Other dogs that are held in high regard by hunters are the visual hunter greyhound dogs and terriers, which were valuable in hunting burrowing prey. Breeding sheep dogs There were also breeders who specialized in working dogs that are used as herders or guides. This included collies, the German Shepherd and the massive St. Bernard. Ladies who wanted companionship proved to be another market for the breeders. Toy and lap dogs such as the Pekingese and the Pomeranian were elevated to â€Å"status symbols† and cuddly playthings. Other companions were the non-sporting dogs the Boston terrier, the bulldog, the chowchow and the Dalmatian. ISSUES CONCERNING THE BREEDING OF DOGS Whatever the dog owner’s reason is for breeding their dogs, the health and safety of the dogs themselves remain at a risk. In the article â€Å"Eight Good reasons NOT to Breed your Dog† by Dr. Elizabeth L. DeLomba, DVM,(2000) she enumerates the following facts that aspiring breeders may not be aware of: 1. Not all dogs are built to breed. Bitches can die during puppy birth. 2. With the massive rise in pet overpopulation and the numbers of dogs that need to be put down in shelters, there are just too many dogs around. 3. Dogs that are not neutered face serious risk of accidents as unaltered males have high tendencies and urges to roam in search of a female. 4. Unspayed females often attract unwelcome attention from dogs of all breeds. 5. Dog labor is not as easy as some people may think. There are instances when dogs need C-sections in order to birth the puppies. 6. Puppy health and survival are not always assured. 7. Not all dogs have the mothering instinct. Puppies can die due to neglect by their mothers. 8. Preparing puppies for sale won’t necessarily bring breeders a wind fall. There are various expenses such as de-worming, vaccine and neo-natal care that are required for newly born puppies. Some believe that putting dogs in shows are not helping them either. While some may argue that the dogs enjoy the outing, there is the stress of performing in a noisy and often tight space crowded with both humans and dogs. Dutch consulting geneticist E. L. Hagedoorn postulates: â€Å"In the production of economically useful animals, the show ring is more of a menace than an aid to breeding. Once fancy points are introduced into the standard of perfection, the breeders will give more attention to those easily judged qualities than to the more important qualities that do not happen to be of such a nature that we can evaluate them at shows. Showing has nothing to do with utility at all, it is simply a competitive game. † (Burns) There have been criticisms that some judges in the popular dog shows do not even know what work the dogs they are judging are capable of doing. Most of the awards are given to dogs that are â€Å"beautiful† and â€Å"fashionable. † Because of this, some show dog owners have taken to cropping the ears and docking the tails of their dogs for cosmetic purposes. The American Veterinary Medical Association (AVMA) is opposed to trimming dog ears for cosmetic and show reasons deeming it as a medically unnecessary and stressful procedure for the dogs to undergo. The AVMA has called on the American Kennel Club and other breed associations to ban dogs with cropped ears from dog shows. (353) Backyard breeders who join shows and obsess about winning ribbons rather than improvement and development of the breed usually last around five years before the interest tapers off according to estimates by the AKC. This often leaves dogs who are beautiful but whose functions and skills have been greatly diminished. â€Å"It is a sad but undeniable fact that breeding to a strict standard of physical points is incompatible with breeding for mental qualities. â€Å"(Lorenz 84) Because awards are given to physically perfect dogs, less attention is paid to the temperament and intelligence of both parent dogs this contention has been proved by the fact that various pure breeds of dog did retain their original good character traits until they fell a prey to fashion. (Lorenz 86) In the article â€Å"The Westminster Eugenics Show† by Jonah Goldberg published in the February 13, 2002 edition of â€Å"The New Republic,† he criticizes the way dog shows such as the Westminster has demoted the functionality and intelligence of dogs into just prancing for a beauty pageant. â€Å"The problem is that Westminster does not judge breeds for those traits which rightly make a breed a breed. The Pointers aren’t asked to point (even though the logo of the Westminster Kennel Club has been a pointing Pointer for over a century). The Bassets and Bloodhounds do not track. The Otter Hounds are not tested to see if they could kill, let alone identify, an otter. And so on and so on. â€Å"With the exception of a handful of breeds who were bred to do nothing but either keep your hands warm or wait until some Aztec chef could cook them, not a single breed at Westminster is expected to do what it was bred to do†¦Ã¢â‚¬  Another issue about breeders is the level of responsibility they are credited with in the euthanasia of animals who have not been fortunate to be adopted from the shelters. Just recently, the People for the Ethical Treatment of Animals (PETA) launched a billboard campaign against dog breeders and their patrons saying that breeding dogs diminishes the chances of those in animal shelters of being adopted. On their web site, the PETA claims that despite whatever good treatment the dogs under the care of breeders and their buyers receive, they cannot be called â€Å"responsible breeders. † According to PETA, if there is anything that dog breeders are responsible for, it is the deaths of the dogs at the animal shelters who could have been adopted had not the option of purchasing a puppy or dog from a breeder was available. All these issues however, have been strongly negated by dog breeders and owners alike. On the PETA message board itself discussing the new â€Å"billboards vs. breeders campaign† buyers have stated that if they were open to buying dogs without knowledge of their backgrounds, health and temperament-wise, they would have gone to shelters in the first-place. (â€Å"What’s up now Breeders? â€Å") Similarly, breeders have posted their defense on the message boards saying that the dogs in animal shelters are the products of irresponsible pet ownership as well as uncontrolled expansion of the dog population through â€Å"puppy mills† and feral dogs that have not been either spayed or neutered. ‘TRUE BREEDERS’ IN SEARCH OF THE PERFECT DOG Nobody can take dogs more seriously than a true breeder. The selection and process of dog breeding is both an intricate and rewarding one. Before anything, dog breeders assess the physical and mental characteristics of a prospective breed of dog. These are vital for dog breeders are tasked not only with breeding and turning out physically beautiful show type dogs but also making sure that these dogs are sound and even-tempered. Everybody who has owned more than one dog knows how widely individual canine personalities differ from each other. No two are really alike any more than human beings are, even among twins; but even in human beings it is possible to pick out individual traits and, by combining them, to explain up to a certain extent the different temperaments, though character analysis can never attain the grade of an exact natural science, owing to the infinite complexity of its subject. The dog’s personality is vastly simpler, and it is much easier to explain the peculiarities of different characters by considering the development of certain ‘characteristic’ traits, and their combinations in the individual. (Lorenz 19). The quest for the perfect dog specimen is an intricate process. Dog breeds and bloodlines are produced by mating dogs with certain desirable characteristics with the purpose of producing young that carry a combination of all these characteristics. POSITION While it is true that despite its noble beginnings Dog breeding has turned into something that can be exploited for financial gain, it is thoroughly irresponsible to lump all breeders under one banner. There are some breeders who truly care about their charges and seek only to preserve that particular breed. Perhaps rather than continually blaming one organization or another for the fate endured by shelter dogs, it would be much better to push for stricter laws regarding the sales and ownership of dogs as well as measures for neutering/spaying feral canines. As for the dog shows, it would be wise to remember that it wasn’t the dog’s choice to be there. There is a need to educate both sides of the argument as to the views of the other. They may both have valid points but too radical and extreme thinking can only bring more harm than good. There has to be some form of compromise. CONCLUSION Dogs as well as other domesticated animals have brought much joy and benefits in their co-existence with human beings. Whether it be for companionship or something more utilitarian, dogs have proven to be man’s best friend in ways that other human’s just cannot. People need to be aware however that the human’s mandate of stewardship includes a responsibility to all creatures under their care. Humans are the stewards of their canine companions. Caring for dogs does not stop at simply feeding them. Bottom line however is whether human or pets, every living thing is entitled to security, protection from harm and respect. It is just a pity and a vast shame that dogs cannot talk and that they cannot be asked what they think of their status and existence in human society. Works Cited Baldwin, Cheryl K. , and Patricia A.

Kenya on Education Essay

Many countries are faced with poverty in this lifetime. Some are more deprived than others. Kenya, a third world country is one of the most deprived areas in the world. The contributions to this issue are: poor education, lack of nutritional foods, high unemployment rates, and insufficient medical needs. Kenya has a very poor education system that are has affected so many young children in the Kenya school district. Many of the children in Kenya should are in primary and secondary schools which should are be funded by the government education free program. The misuse of education is preventing so many children from attention school. Many of these children are very fortunate that their parent can afford to send them to a private school to get best a better education. Many parents are arguing that they believe sending their children to a private school would give themn m better opportunities to their education. The pupil in Kenya reported that most of the private school ss are doing as well as they should and the secondary school s are doing much better. than the TAccord to the center of evaluation for global action stated that the primary and secondary education has poor learning environment, shortage of learning materials ,and teachers due to unemployment,. congestion in classrooms has led to the poor performance. The article also argues that Private schools have all that they need, sufficient learning materials, adequate staff, provision of a good learning environment hence the better results for these school children. The{CEGA}also argues that the usually in Kenya, private primary schools perform far way better than government schools schools ,while in the contrary government secondary schools perform better as compared to the private schools. The article also stated that many of the primary and secondary school s that which are funded by the government are lack of insufficient learning materials such as school libraries, text books, chalks, exercise books , and access to computers which is a key facility since the current world is technology oriented. The school children in Kenya are omitted out of their education, because of the government misuses of donations that whiuch was given toward the childrens education school program, so they can have a brighter and better further future in the world that their theiry are living in. The pundits also argue that the government should not favor pupils from government schools, but to provide a better environment to allow the complete favorably with their counterparts from private schools. The (CEGA) argue that the government had not been employing any teachers for a while since the misuse of school funds. The revenue that that was also collected is was either pocketed by a few or used in political campaigns. This is what the children in Kenya is facing when it comes their education, because most of the citizens in Kenya really do not care if they get an education at all. Also Also sSsome of the private colleges and higher learning institutions were declared illegal and offered substandard education. Pundits all argue that education has been commercialized in Kenya due to the number of new institutions coming up in every building and street in the capital city. It asks the question who is going to registered all these schools?

Learners with cognitive, behavioral and learning disabilities Article

Learners with cognitive, behavioral and learning disabilities - Article Example Thus, issues central to the current interests of educational psychologists have been the subject of discussion throughout the centuries. To understand the characteristics of learners in childhood, adolescence, adulthood, and old age, educational psychology develops and applies theories of human development. "Often cast as stages through which people pass as they mature, developmental theories describe changes in mental abilities (cognition), social roles, moral reasoning, and beliefs about the nature of knowledge"1. "The most influential of these developmental theories is Jean Piaget's theory of development, according to which children mature through four stages of cognitive capability"2. Piaget also proposed a developmental theory of moral reasoning in which children progress from a naive understanding of morality based on behaviour and outcomes to a more advanced understanding based on intentions. Piaget's views of moral development were elaborated by Kohlberg into a stage theory of moral development. The basic underlying concept of both Piaget's and Kohlberg's theories is that these developmental theories are presented not as shifts between qualitatively different stages, but as gradual increments on separate dimensions. These two theories represent the basis for further research and the practical application of the gained knowledge in the field of educational psychology. ... chology to create effective theories and practical application of those theories to assist learners that have cognitive, behavioural and other learning disabilities. When dealing with learners with such problems, there are 2 main aspects to consider: the student with the problem, and the teacher involved in the educational process. Lately, educational psychologists have been focusing more on the teachers, rather on identifying the students with the problems, since in the previous centuries there has been extensive research in that area. Psychologists mostly explore the perception of the teachers of the students, and how teachers adapt to the needs of the student accordingly. This is believed to be the first step towards improving the educational program concerning students with learning disabilities. With the research done by Sheila O. Walker and Robert Plomin, teachers' perception was shown concerning genetic and environmental influence on personality, intelligence, behaviour proble ms, learning difficulties, and mental illness. For these five domains of behaviour, the percentages of teachers who reported that genetics were at least as important as environment were .87, .94, .43, .94, and .91, respectively. They also found that 80% of teachers reported no coverage of genetics during teacher training. (The Nature & Nurture Question: Teachers' perceptions of how genes and the environment influence educationally relevant behaviour; volume 25, Number 5 / October 2005, Educational Psychology). In a another research, which deals with the behaviour problems that high school teachers find most troublesome, found that similar behaviours were reported as troublesome in the secondary school classroom compared with the primary classroom, although differences were demonstrated

Communicating at work Essay Example | Topics and Well Written Essays - 2500 words

Communicating at work - Essay Example Non verbal communication includes memos, emails, and other social softwares. To develop a perfect sort of communication at work it is necessary that some elements are kept into view. This brief would further take all these elements into view and provide with the related needs of communication at work and other places (Taylor 2001). To develop an effective interpersonal communication network at work it is necessary for the individuals to keep several factors in mind while communicating. Businesses nowadays usually are dependent upon the communication networks. For e.g. if an employee needs to get a particular good manufactured, it is necessary for him to contact the manufacturer to tell him what good does he need. Thus it is necessary that an effective network is made. To achieve this it is necessary for the person who is communicating to achieve clarity. By clarity here it is meant that the person who is communicating should be very clear in stating his thesis of the message. The words chosen by the communicator should be very precise which are clear enough for the other individuals intellect. Thus it is necessary that the communicator does not drag his message up to critical levels where the other listener gets confused by the message. This confusion can therefore lead to several other problems in the workpla ce (Kelly 1979 & Taylor 2001). The communicator should make it a point that he is direct when communicating at work. The communicator should not involve irrelevant messages while he communicates as these irrelevant messages can lead to errors at the workplace. The misconception about reaching the point in communication at workplaces is that the communicator usually thinks that adding up other points may give him an advantage but this rather creates an absurd image in which one can miss out the main points of the original message. So it can be concluded that in

Comparative Cybercrime Laws Research Paper Example | Topics and Well Written Essays - 3750 words

Comparative Cybercrime Laws - Research Paper Example To start with, the "global village" or the increased globalization of world trade, involving the need to engage in commerce with nations with unfamiliar legal systems. For another thing, the codification of multilateral associations like the European Union, the African Union, or the Arab League has demanded harmonization of laws of their member states. Moreover, there are publications and Internet resources that assemble legal materials from several jurisdictions, without necessarily undertaking comparisons, but they can be seen as "tools of the trade" for comparative lawyers (Norman 2006). Over the last 100 years, comparative law has emancipated into several distinct branches such as comparative criminal law, comparative tax laws, comparative civil law, comparative administrative law, comparative trade laws, comparative commercial law, comparative cyber laws, Comparative Intellectual Property Law, comparative constitutional law, and comparative constitutional law. According to the prevalent view, Montesquieu is regarded as the 'father' of comparative law. His comparative approach is obvious in the following excerpt from Chapter III of Book I of his masterpiece, De l'esprit des lois: They should be in relation to the climate of each country, to the quality of its soil, to its situation and extent, to the principal occupation of the natives, whether husbandmen, huntsmen, or shepherds: they should have relation to the degree of liberty which the constitution will bear; to the religion of the inhabitants, to their inclinations, riches, numbers, commerce, manners, and customs." Also, in Chapter XI (entitled 'How to compare two different Systems of Laws') of Book XXIX, he advises that 'to determine which of those systems [i.e. the French and English systems for the punishment of false witnesses] is most agreeable to reason, we must take them each as a whole and compare them in their entirety.' Yet another excerpt where Montesquieu's comparative approach is evident is the following one from Chapter XIII of Book XXIX: 'As the civil laws depend on the political institutions, because they are made for the same society, whenever there is a design of adopting the civil law of another nation, it would be proper to examine beforehand whether they have both the same institutions and the same political law.' Applicability of the Comparative Concepts The applicability of comparative concepts is still an open question posed to the discipline of comparative law. Comparative concepts are concepts that are applied in micro-comparative research. They provide with criteria on the basis of which the rules of different legal systems may be compared.

Nature vs. Nurture Essay Example for Free

Nature vs. Nurture Essay A lot of people wonder where they get their freckles from, or their edgy and thrill seeking personality. This type of curiosity about where people get their traits from brings about the worldwide debate on nature vs. nurture. There are scientists who argue that people develop characteristics mainly based on their genetic makeup, and then their are people who say that environment and social interactions has more to do with a person’s traits than do genes. People often question why people are the way they are. Nature and Nurture often have a big impact on a person, and can help in explaining why they are a certain way. The nature vs. nurture debate encompasses a variety of major topics, leading to the idea that both nature and nurture influences people in their behaviors and decisions. Criminals go through different reasoning processes for why they commit a crime. They may have been brought up in a rough environment and are acting out, or because they simply just can not control themselves or their minds. There is evidence which suggests that there could be such a thing as gene mutations that determine our traits. These mutations control how the mind and body react to anger , whether it’s aggressively or controlled. According to Adriel Bettelheim, â€Å"researchers studying a dysfunctional Dutch family announced in 1993 that aggressive behavior may be linked to a single faulty gene that causes a shortage of enzymes needed to break down serotonin molecules that transmit signals in the brain.† This idea that criminal behavior may be associated with genetics, opens the doors to many controversial topics such as the insanity defense or the possibility of gene therapy. â€Å"For many centuries, people have tried to craft legal distinctions for the mentall y ill based on the belief that they should not be held fully responsible for their actions† (). The insanity defense is believed to often be abused and is the easy way out for guilty criminals to be held accountable. There are also people who support the insanity defense and say that the law needs to protect people who are too mentally ill to understand their actions. For some criminals, it’s not just a matter of their genes but more their environment that contributes to why they commit crimes. â€Å"Many social scientists say researchers, in a rush to ‘biologize’ behavior, are ignoring environmental influences, such as poverty, broken families and  racism† (). A lot of times the reason why criminals get in trouble with the law, is because they are acting out. Being aggressive or going against authority is like their coping strategy for dealing with their problems. †The frequency and nature of todays violence can only point toward an inherent anger or frustration† (). Ultimately, both nature and nurture can affect criminals and people ma y never be able to fully understand what exactly leads them to make bad choices. In addition to criminal behavior, there are also many other controversial topics regarding nature vs. nurture, such as intelligence and what contributes to peoples intellectual ability. â€Å"Mental ability seems closely related to the volume of those little gray cells in the brain; and differences in that volume seem to be largely a result of heredity†().Scientists are finding that intelligence goes along with the amount of brain cells (gray cells) towards the front of the brain which can be inherited through the family. There is evidence which suggests that if a person does really well with one mental task, they are more than likely to do really well on other mental tests as well. This concept is considered the general mental ability which is associated with those gray cells. Although intelligence is found as being directly associated with the brain cells, many people believe that intelligence is also based on a person’s environment and how they learn. For a lot of people intellectual ability is not purely genetic. Their intelligence can have a lot to do with how they were brought up or their environment in which they learned. Someone who goes to school regularly will probably have a higher intelligence level, versus someone who doesn’t. How people start off learning is also important because often times, if a child is intellectually stimulated at earlier ages, their brain will mature as the child gets older and that child will have a higher intellectual ability because they started learning sooner. IQ testing is a very controversial topic because many people disagree over whether or not it is a good judge of a persons actual intelligence. â€Å"The rift between psychologists over the value of IQ tests stems from a stark difference in the w ay they define intelligence: One camp sees a central, dominant intelligence, the other envisions multiple types of intelligence† (). Although scientists have not found hard evidence to prove that IQ tests are  not liable, social scientists continue to go against certain theories, such as the idea of general mental ability. They choose to believe and promote that there are different kinds of intelligence and everyone excels in different areas regardless of genetics. While genetics does play a role in intelligence, if a person works hard in achieving their goals they can become just as intelligent through challenging themselves and excelling in certain areas. The worldwide debate on nature vs. nurture also encompasses addiction. In a study about drug addictions researchers found, â€Å"the correlations with psychoactive substance use largely resulted from social environmental factors in adolescence† (). Family environments are important to young children and can have a huge affect on them as they get older. An unstable family life can cause people to resort to drugs or alcohol to help them deal with their emotions. If a child has social issues with their friends when they are young, that can affect them as well and cause them to resort to substance abuse to deal with their problems. â€Å"As people aged, however, more of the correlation in psychoactive substance use resulted from genetic factors†(). As substances such as alcohol are more readily available to adults, genetics can influence them more and also their decisions. If there is a history of substance abuse in the family, that person is more likely to become addicted in their lifetime. In the 1920’s, â€Å"Alcohol prohibition lead to a rise in violent organized crime, a trend critics have compared to the ongoing war on drugs(). Because so many citizens used alcohol and a lot of them apparently became dependent on it, they felt they had rights to it; so they organized a violent crime movement to prove that. People who were involved in this war with drugs were not just the poor or downtrodden, but also the middle class and the wealthy. Addiction has no boundaries, and can affect anyone whether it is through nature or nurture. Nature vs nurture will always be a major dispute over genes and environment, but ultimately they both have an impact on people. The reasoning behind criminal behavior is often questioned. Evidence that suggests there are gene mutations, which contribute to aggressive behavior, argues that nature can have a major role in criminal behavior, just like nature affects criminals  actions. In addition to criminal behavior, another worldwide topic discussed in the nature vs nurture debate is intelligence. Like mentioned earlier, intelligence is thought to be determined by genes and general mental ability; but there are social scientists who believe that there are many different types of intelligence, determined by environment and not just genetic make up. Addiction is another controversial subject because addiction can run in families but it also can happen to someone who had no history of it. Addiction also is very much related to a persons environment and how they deal with their problems. For those who wonder where they get their intelligence and edgy personality, or more seriously why they feel aggressive, or become addicted to drugs, think about nature and nurture , which contribute to peoples personality and traits.
