Kenneth Oppel has developed the main character, Matt Cruse, very well using Joseph Campbell`s theory on the archetype of the hero`s journey. The novel`s main character, Matt Cruse, is a hero because of his call to destiny, his journey in the book, and the return, reward and reintegration in to the society. Firstly, the evidence that proves that Matt Cruse is a hero in this book is the fact that he was called to his destiny. There are two evidence that lead up to Matt Cruses` destiny. The two evidence are when he rescued Benjamin Molloy and when Benjamin was about to die, Benjamin Molloy said about magnificent creatures that he saw but Matt passed those predictions as the ravings of a dying man. The second evidence that proves that he was called to his destiny is the fact that Kate De Vries, second female character, comes on board the aurora and tells Matt that the man that Matt saved a year before was her grandfather, Kate trusts Matt enough to let him see her grandfather’s diary. Matt reads about what Kate’s grandfather saw and gets amazed and starts to believe that the creatures really exist. Matt rescues Benjamin Molloy, Kate’s grandfather, in the first chapter where all the characters are introduced and the captain asks matt to go in an arm that is aboard the aurora and rescue the damaged man in the hot air balloon. Hero’s are always brave and so is Matt. â€Å"â€Å"Mr. Cruse, I look at you, and of all the men, you’re the one who shows not the slightest hint of fear. Am I right? â€Å"Yes, sir. I have no fear of heights. † Matt said †

Plessy vs. Ferguson :: essays research papers

Plessy vs.Ferguson   Ã‚  Ã‚  Ã‚  Ã‚  The case of Plessy vs. Ferguson started when a 30-year-old colored shoemaker named Homer Plessy was put in jail for sitting in the white car of the East Louisiana Railroad on June 7, 1892. Even though Plessy was only one-eighths black and seven-eighths white, he was considered black by Louisiana law. Plessy didn’t like this idea, and so he went to court and argued in the case of Homer Adolph Plessy v. The State of Lousiana that the Separate Car Act, which forced segregation of train cars, violated the Thirteenth and Fourteenth Amendments to the Constitution. The Thirteenth Amendment was made in order to abolish slavery, while the object of the Fourteenth Amendment was to enforce the absolute equality of the two races before the law. The name of â€Å"Ferguson† was given to the case because the judge at the trial was named John Howard Ferguson.   Ã‚  Ã‚  Ã‚  Ã‚  Judge Ferguson had previously declared that the Separate Car Act was unconstitutional on trains that traveled through several states, but he ruled that within the state, the state government could choose to regulate the railroad companies that operate within their respective state. The ruling was that the judge found Plessy guilty of refusing to leave the white car. Plessy proceeded to appeal to the Supreme Court of Louisiana, which also found him guilty. In 1896, the Supreme Court of the United States heard Plessy’s case and found him guilty once again.   Ã‚  Ã‚  Ã‚  Ã‚  My view on this particular case sides with Plessy rather than Ferguson. I believe in total equality and the idea of no difference between fellow human beings. There should be no distinction made between that which is for the white man, and that which is for the black man.

Genetically Modified (Gm) Foods Essay

The Term â€Å"Genetically Modified (GM) foods† refers to crops produced for human or animal consumption using the recombinant DNA techniques. The world population is growing in a fast pace such that it is expected to double in the next 50 years. Supplying food to this growing population is a major challenge. GM foods can be considered as the major solution for the food security. These foods are produced by the modification of crop plants in the laboratory to enhance desired traits, mainly biotic and abiotic stress tolerance, improved nutritional content, etc. These traits were earlier carried out through conventional plant breeding, but these breeding methods are very time-consuming and often not very accurate. However, with recombinant DNA technology, plants with the desired traits can be produced, very rapidly and with greater accuracy. Process Recombinant DNA technology begins with the identification and isolation of a gene which expresses a desirable trait, with the aid of restriction enzymes. Then a recipient plant or animal is selected, and the gene is inserted and incorporated into its genome through a vector such as agrobacterium, through a gene gun shooting an elemental particle covered in plasmid DNA, electro oration, or a virus. Once part of the recipient, the newly inserted gene becomes part of the genome of the recipient and is regulated in the same way as its other genes. For example, we can isolate a gene responsible for conferring drought tolerance, introduce that gene into a plant, and make it drought tolerant. Crops can also be transformed using non-plant genes such as the use of Bt genes, in cotton and many other crops. Bt, or Bacillus thuringiensis, is a naturally occurring bacterium that produces crystal proteins that are lethal only to insect larvae. Bt crystal protein genes have been transferred into cotton, soya, corn, brinjal, enabling the plants to produce its own pesticides against insects such as the American bollworm, European corn borer. Bt genes are lethal only in the acidic medium, insect gut environment and do not get activated in an alkaline environment, prevalent in humans and other animals that feed on these plants. BENEFITS OF GM FOODS Drought tolerance/salinity tolerance: As the world population grows and more land is converted for housing instead of food production, farmers need to grow crops in non-arable land, previously unsuited for plant cultivation. Creating plants that can withstand long periods of drought or high salinity in soil and groundwater will help people to grow crops in large, barren wetlands/dry lands in our country. Pest resistance: Insect Pests are causing devastating financial loss for farmers, sometimes starvation. Indiscriminate use of pesticides is also a potential health hazard, and the run-off of agricultural wastes from excessive use of pesticides and fertilizers poisons the water supply and harms the environment. Ex: Growing GM foods such as Bt brinjal helps reduce the application of pesticides substantially, as 80 per cent of brinjal crop are infested with pests. Disease resistance: There are many viruses, fungi and bacteria that cause plant diseases and thereby contribute to yield loss. Plant biologists are working to create genetically engineered plants with resistance to these diseases. Ex: Developing sheath blight resistance in rice. Cold/heat tolerance: Farmers are facing the vagaries of weather, like unexpected frost or excess heat due to climate change. Researchers have identified an antifreeze gene from cold-water fish and introduced it into plants such as tobacco and potato to study the efficacy of the plant to withstand extreme temperatures. Also, research is on to identify plants that can survive excess heat, submergence tolerance etc. Nutrition: People in our country suffer from various nutrient deficiency diseases due to malnutrition. Most of the people rely on rice as a major staple food. But rice does not contain adequate amounts of all necessary micro and macronutrients. If rice could be genetically engineered to contain additional vitamins, iron and/or minerals, nutrient deficiencies could be alleviated. For example, MSSRF (M. S. Swaminathan Research Foundation) are working on improving the iron content. Phytoremediation: Soil and groundwater pollution continues to be a problem in many parts of the world. Plants such as poplar trees, brassica spp are being genetically engineered to clean up heavy metal pollution from soil contaminated with metals like lead, arsenic, and cadmium. Concerns Most concerns about GM foods fall into three categories Environmental hazards: Unintended harm to other organisms; reduced effectiveness of pesticides; gene transfer to non-target species are some of the concerns of the environmental concerns of GM crops. Human health risks: Allergenecity, unknown effects on human health are some of the main health concerns. For example, Pioneer Hi-Bred tested the allergenicity of a transgenic soybean that expressed a Brazil nut seed storage protein in hope that the seeds would have increased levels of the amino acid methionine. The tests (radio allergosorbent testing, immunoblotting, and skin-prick testing) showed that individuals allergic to Brazil nuts were also allergic to the new GM soybean. Economic concerns Environmental activists, religious organizations, non-governmental organizations have criticized agribusiness for concentrating on profits through GM Foods without concern for potential hazards. They also criticized the government for failing to start a regulatory body. All GM crops should be subjected to thorough regulatory processes and toxicology and allergenicity tests data needs to be shared with the regulatory authorities prior to commercialization. Government Role Many new plant genetic engineering technologies and GM plants have been patented, and patent infringement is a big concern of agribusiness. So, bringing GM food to market is a lengthy and costly process. This is a genuine concern and therefore it is important for the government to fund and support public sector research in reputed universities or agriculture institutes to ensure quality research and also keep prices under check. Conclusion Government should check all the hazards, environmental, health and economic concerns and then decisions should be taken to commercialize a GM product. Though ambiguity during the process, once they get regulatory approve, it implies that they have been subjected to stringent scrutiny and are safe for commercial release. So, the governments around the world are hard at work to establish an effective regulatory process to monitor the effects of and approve new varieties of GM plants. According to M S Swaminathan, the chairman of the National Commission on Farmers, GM foods have the potential to solve many of the world’s hunger and malnutrition problems, and can protect and preserve the environment by increasing yield and reducing reliance upon chemical pesticides. Yet there are many challenges ahead for governments, especially in the areas of safety testing, regulation, international policy and food labeling.

Essay about Learning Theory - 1887 Words

Learning is defined as a, relatively permanent change in an organisms behavior due to experience (Myers, 2010). The purpose of this paper is to present a critical analysis of the different theoretical approaches and explanations for learning through an examination of the theories of behaviorism, social learning and cognitive. I will investigate the principles and postulates of each theory, their strengths and their weaknesses. It is my belief that because each theory is best applicable to varying types of learning, it is best that a combination of each is used to provide the most complete learning experience. Behaviorism is a theory that focuses on objectively observable behaviors, while discounting mental activities.†¦show more content†¦Furthermore this theory provided a basis for John Watsons idea that, human emotions and behaviour...are mainly a bundle of conditioned responses (p. 235 ) which is applicable to the treatment of such psychological disorders as phobias. For example, to treat a patient with a fear of spiders, one might attempt to remove the phobia by counteracting conditioning: learning a response that is unsuited with fear. Classical conditioning has been very useful in the treatment of substance abuse in which therapy includes an avoidance of settings associated with the use of that substance, as well as an actual reversal* of such positive associations using aversive experiences (p 235). However, not all learning is a simple association between conditioned and unconditioned stimulus, but rather it involves a complex array of cognitive and biological contributions. The failure to recognize the cognitive processes involved in learning results in the acquired expectancy that the unconditioned stimulus (UCS) will occur. This is known as predictability. For example, the association between alcohol and nausea in the presence of a nausea-inducing drug, is lessened by the alcoholics awareness of the drug (p 233). Also, the theory fails to account for the biological constraints on an animals capacity for conditioning. Rather than Pavlovs belief that any perceivable stimulus can serve as a conditioned stimulus (CS), it is more realistic that each speciesShow MoreRelatedLearning Theories : A Learning Theory1164 Words   |  5 Pages Learning theories video script 8) What is meant by learning theories?
