Obstacles Teachers May Face free essay sample

The process of how an individual learns is based on the theories surrounding behaviorism, conditioning, modeling and self regulation. Students can be problematic if proper resolutions aren’t put in place when a dilemma arises. There is a great emphasis on the importance and relevance in motivating the students in the classroom. Without the knowledge of extrinsic and intrinsic motivation and what drives students to learn, teachers may not know what inspires or how to encourage students to work to the best of their ability. Teachers must portray themselves in a professional manner at all times, whether they are dealing with students, parents or colleagues. Professionalism can be defined in several ways and some characteristics of a professional teacher include being committed to learners in a way that incorporates a code of ethics, have the ability to make routine and efficient decisions in a complex and ill-defined situation, conduct a critical self examination of one’s teachings, i.

Kauchak, D. 2010. pp, 4 – 6). One obstacle a teacher may face is if he or she gets asked a question that they don’t know the answer to. Students look up to teachers and depend on them for the knowledge they require (Yero, J. L. , 2002. P173). Understanding each topic is simply not enough; a teacher needs to be able to represent topics in an understandable way that is appropriate to the age of the learner. For example, the solution to explaining how to multiply numbers is to firstly acquire the knowledge of content then illustrate how to multiply the numbers. This is referred to as pedagogical knowledge. Pedagogical knowledge requires the teacher to understand principles of instructional strategies and classroom management. Involving each student in the learning process in order to enhance productive learning comes with knowledge and experience. Instructional strategies that promote productive learning include: selecting topics that are important for students to learn, provide clear learning objectives and prepare learning activities respectively, design assessments that relate to the workload and maintain the instructional alignment between the three, i. e. the connection between learning objectives, learning activities and assessments (Eggan, P. Kauchak, D. 2010. pp390 – 394). A teacher must have a positive and caring attitude, be organized, communicate effectively, respect and encourage rather than punish and constantly question and prompt incorrect answers to manage a productive classroom (Nelson, J. , Lott, L. Glen, S. p20-27). Identifying clear standards of acceptable behavior i. e. rules, be supportive to each student and create a sense of equilibrium are all strategies to ensure a produc tive and manageable classroom. The aim of all teachers is to promote as much learning as possible. Behaviorism focuses on the idea that learning is â€Å"influenced by stimuli from the environment† (Eggan, P. Kauchak, D. 2010. p,164). For example, feeling nervous before an exam is a learned behavior due to previous experiences/knowledge of exams. This feeling is involuntary to the individual, and it is referred to as classical conditioning. Classical conditioning can be positive or negative, depending on which, it can have different effects on the learner. If the teacher uses positive reinforcement within the classroom the students will gradually associate learning to the teacher’s manner and thus feel safe within the classroom resulting in a productive learning environment. In contrast negative or non-reinforcement results in the cessation of a behavior and results in a classroom environment that is not productive. Children learn acceptable behaviors through observing adults, therefore teachers are role models, and it is important for a teacher to demonstrate respect, tolerance, and values to motivate learning (Call, N. Featherstone, S. 2004 p. 47). Cognitive modeling is essential to the learning process as teachers use this to perform a demonstration and verbalize the thinking behind the actions taken (Eggan, P. Kauchak. D. , 2010. p. 182). An obstacle one may face is if some children are having trouble learning how to pass a netball to one another. Often, children instinctively bounce the ball, instead of passing it, as clas sical conditioning has taught them to do so from a young age. The teacher must describe one’s thoughts of how to pass a netball, whilst performing the action, which in turn encourages students to verbalize their understandings in any situation, resulting in a productive learning environment. Modeling is the key concept of social cognitive theory. Cognitive, behavioral and emotional change in children is a result of observing models. Modeling affects people by learning new behaviors, facilitating existing behaviors, changing inhibitions and by arousing emotions (Eggan, P. Kauchak, D. 2010. p. 183). These observations lead to learner expectations, which in turn are accomplished through self-regulation. Settings goals and monitoring that progress is an essential element of learning. The student observes another student passing the netball. He then models the observation, uses that experience to expand his knowledge thus takes responsibility and control of his learning. Teaching is constantly developing and changing, and the need for motivation is a necessary procedure to support and increase student learning and the teaching process. A common obstacle teacher’s face is how to motivate uninterested and unengaged students. Some students seem naturally enthusiastic about learning, but many need or expect their instructors to inspire, challenge and stimulate them. An unmotivated student is likely to choose work that is inappropriately easy, show a negative attitude, give up quickly and leave tasks unfinished. This can disrupt the students around him and cause interruptions in the learning environment (Nelson, J. Lott L. , Glenn, S. 1997 p. 72). There are two broad forms of motivation; extrinsic – where some students will be motivated by the approval of others, for example, by getting a good grade, and intrinsic motivation, where the learner studies in order to understand the content presented to them because they like the challenge and want to perform (Eggen, P. Kauchak, D. 2010. p. 287). To encourage students to become self motivated and independent learners, teachers can give frequent, early, positive feedback. This supports the students beliefs’ that they can, and are doing well as viewed by the humanistic theory of motivation. The teacher can also help students find personal meaning and value in the material as viewed by cognitive and social cognitive theory of motivation, and create an atmosphere that is open and positive which help students feel that they are a valued member of the learning community which is based on the socioculural theory of motivation. In addition, a teacher can ensure opportunities for students’ success by assigning tasks that are neither too easy nor too difficult which is a view shared by behaviorist theories (Eggen, P. Kauchak, D. 2010. p. 289). It must be understood that individuals are motivated through a wide variety of needs. While teachers can’t make or teach students to be self-motivated, they can encourage and promote this highly desirable trait. To conclude, there are many solutions to the obstacles a teacher may face in a learning environment. A teacher should act and approach a classroom with a professional attitude and an academic manner by being knowledgeable and recognizing the importance for assessing oneself. Teachers must be aware of the influence they make on students’ learning and how to promote positive and engaging classroom environments in order to solve the dilemmas they may be presented with in regards to behaviors students display. Furthermore, teachers need to understand that the process of motivation stems from stimulation, which in turn is followed by an emotional reaction that leads to either a positive or negative behavioral response. By understanding the theories based on solutions to the problems a teacher may face in the classroom, they may have a better chance at expecting when a problem may arise, and resolve the situation immediately.

John D Rockefeller American Philanthrapist essays

John D Rockefeller American Philanthrapist essays During the late 1800's and early 1900's the oil industry was a monopoly that was created by one man. Some people would describe this man as a ruthless, cruel, cutthroat business tycoon. This man was John Davison Rockefeller. John D. Rockefeller made the Standard Oil Company, becoming America's first billionaire, and then gave away more than half his fortune to charities. John Rockefeller was a dedicated businessman who built himself an empire from nothing and helped others with his generous donations. His business ended up helping smaller businesses because of the new laws and restrictions that needed to be created in order for the U.S. government to have a handle on the Standard Oil Company. John D. Rockefeller changed the oil industry, created and greatly contributed to many charities in America. Rockefeller was born on July 8, 1839 in Richford, New York (J.D.R. J.D.R. Page n.p.). He married Laura C. Spelman (1839-1915) on September 8, 1864 (Rockefeller Family and Associates n.p.). His mother, Eliza Davison Rockefeller, was very religious and disciplined, she was the person who taught him to work hard, save and give to charities (J.D.R. J.D.R. Page n.p.). Rockefeller's mother had the biggest influence on him involving his religion and philanthropy. John D. Rockefellers father, William Avery Rockefeller, was a "pitch man" or a doctor that says he can cure cancers for a fee (J.D.R. J.D.R. Page n.p.). John and Laura Rockefeller had four girls and one boy (Rockefeller Family and Associates n.p.). The one boy they did have, John Davison Rockefeller Jr. (1874-1960), went on to continue his father's work and make the Rockefeller name a well-liked one instead of one that was a bitter reminder of his father's business techniques (Rockefeller Family and Associates n.p.). John D. Rock efeller died on May 23, 1937 in Ormond, Florida after retiring from the oil industry in 1911 (J.D.R. Encyclopedia of World Biography Vol. 13 228). Rockefel...

The Wonder of Motion Pictures - Movie Review Example The opening credits start off in the Locker-room of the Tyrell Corporation during the day with the words, "It's magnified and deeply revealed. Flecks of green and yellow in a field of milky blue. Icy filaments surround the undulating centre," ("Blade Runner" p.1). Interpreting the author's choice of words, the 'field of milky blue' appears to be the sky itself. This description falls within the definition of Mimesis being that it uses descriptive tone to introduce a visual understanding of a scene. While it also fits within the parameters of Diegesis based on telling the reader at the beginning where they are, it uses more of Mimesis. The next paragraph deals more so with verbal choices that give a better sense of the physical environment for which the story is taking place. While there is a continued mention of colour, there is also an addition of 'hard' words to describe the items within the scene. Such as, "The eye is brown in a tiny screen. On the metallic surface below, the words VOIGHT-KAMPFF are finely etched. There's a touch-light panel across the top and on the side of the screen, dial that registers fluctuations of the iris," ("Blade Runner" p.1). ... With that being said, the previous paragraph detailing the milky blue and the flecks of green and yellow, in keeping with the theme of the iris, may actually be tied in together with the description of a human eye. The 'field of a milky blue' would be if one was to look into the eye of a person whose iris was blue. It is common for people to have small particles of a different colour that lies within their eye, so the 'flecks of green and yellow' would be the slight colour imperfections within the eye itself. As the script goes further, the author uses narration to give the story a clean movement from beginning to end. The reader is able to keep in line with how the story is intended to proceed. The frequency of descriptive words plays into the author's narration intent. For a piece of work to be best comprehended and ultimately enjoyed, the narrative has to be at which a clearer picture is given of what it is that is trying to be said in the first place. The following two paragraphs are important to mention, especially in deciphering the intent of their usage, and the meaning of how the author may intend to have the story play out.

Final exam - Essay Example On the subject of externality there is the aspect of Negative Externality and it involves both the consumer and the producer who collectively neglect the environment and what implications their activities have on the environment. It could also involve one of the two parties leaving the other out of consideration; for example when a producer releases a harmful product into the market and it results into the death of a consumer. This is one scenario that has been satisfied by the tobacco company. The health effects (lung cancer) of smoking to both the active and passive smokers cannot be over emphasized. The medical bills that the smoker incurs in the course of treatment is substantial and then there is the pain endured during ones illness and the ultimate price is the loss of life. Regardless of these hazardous effects, the cigarette industry continues to thrive over financial gains from the sale of its product. In the United States, the Food and Drug Administration (FDA) has controlled the tobacco company through the regulation of their products. It has done this by: restricting the advertising and promotion of tobacco products and this has worked to promote healthy living since the public is less aware of the existence of the product. It has banned all tobacco products which are flavored like fruits and candy and this has made them less attractive to minors and individuals with refined tastes. The companies are barred from purporting any reduced risk products and this has played the role of reducing the number of new smokers or prospective ones. It requires the companies to fully disclose the health effects of their product, the contents and any changes they might have made; with this knowledge in the public eye, the consumers are empowered with information. The disadvantage that comes with these legislations is that the sale of the product is still legal so long as the relevant companies abide by them. The

Theories of Temperament: An Overview

Theories of Temperament: An Overview The literal meaning of personality springs from the Latin word ‘persona’, the mask employed by roman theatre actors. personality refers to our characteristics ways in which of responding to people and things. Personality is characterised by the subsequent features:- it has both physical and psychological parts. Its expression in terms of behavior is fairly distinctive in an exceedingly given individual. Its main options dont simply modification with time. its dynamic within the sense that a number of its options could change thanks to internal or external situational demands. Definitions of personality While there are many alternative theories of personality, the primary step is to know specifically whats meant by the term personality. The word personality itself stems from the Latin word persona, that referred to a theatrical mask work by performers so as to either project totally different roles or disguise their identities. A brief definition would be that personality is created from the characteristic patterns of thoughts, feelings and behaviours that create someone unique. additionally personality, personality arises from inside the individual and remains fairly consistent throughout life. Some other definitions of temperament as given by some psychologists are: †¢ Personality refers to individuals characteristic patterns of thought, emotion, and behavior, along side the psychological mechanisms hidden or not behind those patterns. This definition means among their colleagues in different subfields of science, those psychologists United Nations agency study temperament have a novel mandate: to clarify whole persons. (Funder, D. C., 1997) †¢ Although no single definition is suitable to all or any personality theorists, we will say that temperament could be a pattern of comparatively permanent traits and distinctive characteristics that offer each consistency and individuality to an individuals behavior. (Feist and cur, 2009) Components of temperament So what specifically makes up a personality? As described within the definitions higher than, one would expect that traits and patterns of thought and feeling frame a crucial half. a number of the other basic characteristics of temperament include: Consistency theres typically a recognizable order and regularity to behaviors. basically, individuals act within the same ways in which or similar ways in which in an exceedingly style of things. Psychological and physiological temperament could be a psychological construct, however analysis suggests that its conjointly influenced by biological processes and wishes. It impacts behaviors and actions temperament doesnt simply influence however we tend to move and respond in our environment; it conjointly causes North American country to act in bound ways in which. Multiple expressions temperament is displayed in additional than simply behavior. It may be seen in our thoughts, feelings, shut relationships and different social interactions. THEORIES OF temperament Personality contains a long history ranging from mathematician, Plato, Aristotle, solon and varied different philosophers and writers. Plato Plato (427–347 BCE) outlined the human soul because the seat of temperament. in keeping with philosopher the soul consists of 3 basic forces guiding human behavior: reason, emotion, and appetence. Reason is given the very best price because it keeps the additional primitive forces of appetence and feeling treed whereas feeling and particularly appetence area unit considered the â€Å"lower passions.† Aristotle Aristotle (384–322 BCE), one in every of Plato’s students and also the teacher of Alexander the good, noted human soul because the psyche. Aristotle projected that the psyche is that the product of biological processes. He additionally saw the psyche as as well as a collection of faculties that he placed during a hierarchy of importance. the primary school that Aristotle distinguished is that the nutritive—the human organism’s basic drives to fulfill its bodily desires. This school is found in plants further as in animals and other people. successive and better school is that the sensory activity, that philosopher outlined because the facet of mind that interprets sensory information. Animals further as folks have a sensory activity school. The last and highest school is that the intellectual, that philosopher saw as distinctive to kith and kin. Descartes According to Renà © mathematician (1596–1650), a French thinker, human temperament is that the product of the interaction of divine and primal forces. He saw the essential force behind human temperament because the immortal soul—pure, perfect, and intangible. mathematician started to clarify however this religious entity interacted with the material body. His observation of associate anatomical dissection semiconductor diode him to suppose he had resolved this mind-body downside. He detected atiny low body within the apparent center of the brain referred to as the epiphysis cerebri or epiphysis cerebri, therefore named by the Greco-Roman MD Claudius I Galen (c. 130–c. two hundred CE) as a result of its form reminded him of a pine cone. Descartes(1649) came to the conclusion that that this conical endocrine gland should be the purpose of contact between the soul and also the body. philosopher philosophical system, that is that the philosophical position that 2 su bstances—matter and spirit, or brain associated mind—exist severally of every different though they interact—became the foremost common read within the Christian West when the seventeenth century as a result of it â€Å"explained† the existence of human discretion and consciousness in an otherwise mechanistic universe. Indeed, before the appearance of the pc, it appeared not possible to permit for consciousness while not appealing to nonmaterial ideas. Machiavelli Niccolà ² Machiavelli (1469–1527), a Florentine diplomat and political thinker, believed that temperament is best understood in an exceedingly social context. in keeping with Machiavelli, folks area unit basically egotistic, greedy, ungrateful, and unforgiving. moreover, he saw 2 primary forces as process human character. the primary one is associate Italian term—virtà ¹Ã¢â‚¬â€which is best described as a mix of positiveness, fearlessness, and assurance. Machiavelli referred to as the second force Fortuna, that is that the Latin word for luck. someone might become a robust leader with the assistance of an honest dose of virtà ¹ and Fortuna. in keeping with him leaders United Nations agency act out of kindness and a believe the essential goodness of humanity can continuously fail. This belief is usually expressed by modern folks as â€Å"nice guys end last.† There are variety of different theories regarding however temperament develops. totally different schools of thought in science influence several of those theories. Type theory of temperament Perhaps the earliest acknowledged theory of temperament is that of the Greek MD Hippocrates (c. 400 B.C.), United Nations agency characterised human behaviour in terms of 4 temperaments, every related to a unique humour, or humour. The sanguine, or optimistic, kind was related to blood; the unemotional kind (slow and lethargic) with phlegm; the melancholic kind (sad, depressed) with black bile; and also the choleric (angry) kind with bodily fluid. Individual temperament made up our minds by the number of every of the four humours. Hippocrates system remained authoritative in Western Europe throughout the medieval and Renaissance periods. abounding references to the four humours is found within the plays of playwright, and also the terms with that Hippocrates tagged the four temperament sorts area unit still in common use nowadays. the idea of temperaments is among a spread of systems that influence human temperament by dividing it into sorts. A wide popularized (but scientifically du bious) trendy assortment of temperament was developed within the Nineteen Forties by William Sheldon, associate yank man of science. Sheldon classified temperament into 3 classes supported body types: the someone (heavy and easy-going), person (muscular and aggressive), and individual (thin and intellectual or artistic). Trait theory of temperament A major weakness of Sheldons morphological arrangement and different kind theories generally is that the component of oversimplification inherent in inserting people into one class, that ignores the actual fact that each temperament represents a novel combination of qualities. Systems that address temperament as a mix of qualities or dimensions area unit referred to as attribute theories. Well-known attribute intellectual Gordon Allport (1897-1967) extensively investigated the ways in which during which traits mix to create traditional personalities, cataloguing over 18,000 separate traits over a period of thirty years. He projected that every person has about seven central traits that dominate his or her behavior. Allports commitment to building attribute analysis additional manageable and helpful by simplifying it had been expanded by future researchers, United Nations agency found ways in which to cluster traits into clusters through a method referred to as correlational analysis. Raymond B. Cattell reduced Allports in depth list to sixteen basic teams of inter-related characteristics, and Eysenck claimed that temperament can be delineate supported 3 basic factors: psychoticism (such delinquent traits as cruelty and rejection of social customs), introversion-extroversion, and emotionality-stability (also referred to as neuroticism). Hans Jurgen Eysenck conjointly developed a quadrant supported across emotional-stable and introverted-extroverted axes.

How Toy Story Helps Children Navigate Technology Essay -- Technology

Technology is rapidly growing â€Å"to infinity and beyond† from games to cars, modern technology fully encompasses our daily lives leaving society helpless without it. In the early 90’s, society knows little of how much this new technology eventually influences their children’s lives, so parents portray outwardly no problems with having companies heavily advertising new electronic products to children. The results change the world. Now, technology intertwines with the fast-paced lives of the society, leaving some frustrated parents finding it difficult on ways to teach their children to balance both modern technology and manual labor. Wisely, parents start to rely on the first thing that originally got them into them mess - the magical world of Pixar. The original Toy Story focuses on the societal view of the celebration towards the advancement of technology during the time the movie releases in 1995, which is what society needs at that time. However, by Toy St ory 3(2010), young adults actively disengage in the usage of the consumerism for the latest-and-greatest technology, so the tone of the movie sequel changes. Toy Story 3 actively encourages youth to enjoy the makings of the past without overlooking the new technological advancements. Toy Story, one of the first cartoon using the new animation technology, highlights one boy’s (Andy’s) first experience with technology, Buzz Lightyear, the most popular and advanced toy at that time. Andy is quickly amazed at the impressive high-tech features of Buzz and excited about the technology of Buzz. Andy starts losing his love for his old manual toys like Woody; Woody fears that Buzz is the new favorite toy in Andy’s life. At this time, the society starts to bring the technology into th... ...etc.) Back in 1995 when companies start releasing technology like computers, cell phones, and media players to the general public, Toy Story tries to encourage, introduce, and make technology interesting for kids; allowing them not to be afraid of the inevitable surge of technological advancements late 90s-early 2000s. In today’s modern-life, there is no huge need of encouragement for people to use the technology; although, there is a need to remind society that don’t over let technology overrun your life no matter how useful.

A Cycle Is a Biological Pathway or Process in Which the End Product

A cycle is a biological pathway or process in which the end product of one cycle becomes the starting point for the next cycles Write an essay about cycles. Respiration Cells in the body use ATP as a direct source of energy. The conversion of glucose into ATP takes place during respiration. There are 2 different types of respiration, the more common and frequent one is aerobic respiration which is the production of ATP for energy. The less common one is anaerobic respiration, the production of lactate during which the muscles have a limited supply of oxygen, and however keep working despite this.Aerobic respiration requires oxygen and glucose present to work, and occurs in 4 stages: 1) Glycolysis- the splitting of a 6-carbon glucose molecule into 2 3-carbon pyruvate molecules. There is a net gain of 2 ATP’s produced. 2) Link reaction- the conversion of the 3-carbon pyruvate molecule into carbon dioxide and a 2-carbon acetyl co-enzyme A molecule. No ATP is produced during this stage. 3) Krebs cycle- the introduction of acetyl co-enzyme A into a cycle of oxidation-reduction reactions that yield some ATP and a large number of electrons. ) Electron transport chain (ETC) – electrons used from Krebs cycle to synthesise ATP with water produced as a by-product. Glycolysis is the initial stage of aerobic respiration, and it takes place in the cytoplasm of cell. It is the breakdown of glucose into pyruvate, (which then goes in to initiate the second stage, the link reaction, and so forth) although there are a number of smaller enzyme controlled reactions for tis to take place. 1. Activation of glucose by phosphorylation.Before glucose can be split into 2 pyruvate molecules, it first must be made more reactive by the addition of 2 phosphate molecules, donated by the hydrolysis of 2 ATP molecules to ADP. This provides the energy to activate glucose. 2. Splitting of the phosphorylated glucose. Each glucose is split into 2 3-carbon molecules of triose phosphate . 3. Oxidation of triose phosphate. Triose phosphate is oxidized transferring 2 hydrogen molecules to a hydrogen-carrier, NAD to produce reduced NADH. 4. Production of ATP. Enzyme-controlled reactions convert each triose phosphate into 3-carbon pyruvate. molecules of ATP are regenerated from ADP. The pyruvate molecules produced in the cytoplasm during glycolysis are actively transported into the matrix of the mitochondria where the link reaction takes place. Pyruvate undergoes a series of reactions to be made into acetyl co-enzyme A. the following changes occur. * Pyruvate is oxidised by the removal of hydrogen. This hydrogen then binds to NAD to produce reduced NADH (which is later used to produce ATP late). * The 2-carbon molecule acetyl group that is thereby formed combines with a coenzyme, coenzyme A (CoA) to produce Acetyl CoA. A carbon dioxide molecule is formed from each pyruvate. Pyruvate + NAD + CoA acetyl CoA + reduced NADH + CO2 The Krebs cycle involves a series of oxidat ion-reduction reactions that take place in the matrix of mitochondria. * the 2-carbon acetyl CoA from the link reaction with a 4-carbon molecule to produce a 6-carbon molecule. * This 6-carbon molecule loses carbon dioxide and hydrogen’s to give a 4-carbon molecule and a single molecule of ATP produced as a result of substrate-level phosphorylation. The 4-carbon molecule can now combine with a new molecule of acetyl CoA to begin the cycle again. The ETC takes place in the cristae of the mitochondria, where ATP is synthesised using the ETC as followed; * The H+ atoms produced during glycolysis and the Krebs cycle combine with the NAD and FAD that are attached to the cristae. * The reduced NAD and FAD donate the e- of the hydrogen atoms they are carrying to the first molecule in the ETC * This releases the protons from the hydrogen atoms and these protons are actively transported across the inner mitochondrion membrane. The e- meanwhile, pass along the ETC molecules in a series of oxidation-reduction reactions. The e- lose energy as the pass down the chain, some of this is used to combine ADP and inorganic phosphate to produce ATP. The remaining energy is used to from heat. * The protons accumulate in the space between the 2 mitochondrion membranes before they diffuse back into the mitochondrion matrix via protein channels. * At the end of the chain the e- combine with the protons and oxygen to form water.Oxygen is therefore the final acceptor in the ETC. Photosynthesis Photosynthesis occurs in 2 stages. The light-dependent reaction which takes place in the thylakoid, and the light-independent which takes place in the stroma. Both are vital for the production of ATP. The light-dependent needs light to undergo its reactions. The thylakoid contains chlorophyll which absorbs light. Photophosphorylation occurs during this reaction which is the making of ADP plus an inorganic phosphate to make ATP.NADP is also reduced during this reaction into NADPH. As well a s this happening in the light-dependent reaction, water is split via photolysis in to protons and electrons and oxygen which diffuses out of the leaf. The light-independent reactions does not require light to process, however it does rely on 2 major products of the light-dependent reaction to take place, ATP and NADPH. This reaction is shown in the form of the Calvin cycle. * CO2 enters the stroma from the light-dependent reaction, and produces 2 3-carbon glycerate-3-phosphate. 2 ATP molecules then donate 2 phosphate molecules to produce ADP. And NADPH is oxidized to produce NADP. This goes on to form 2 3-carbon triose phosphate molecules. * 1-carbon from the triose phosphate molecule is then stored to contribute to making glucose. ATP is then reduced again donating a phosphate molecule to produce 5-carbon rubiscose bisphosphate, this in turn then produces and enzyme rubisco which catalyses the whole cycle again. * This cycle must happen 6 times in order to make 1 glucose molecule.

In Cold Blood Report essays

In Cold Blood Report essays Truman Capote, in his work In Cold Blood, used a conventional form of language to capture the reader in suspense. There were, in fact, styles of writing that he purposely neglected to use. He deviated from the norm to create an effect that would allow the reader to interpret different views from the story. Of the conventional ideas of writing that Capote neglected, keeping the story in one setting at all times was among them. During his era, writers would take a story and focus on one main idea to follow it through to the conclusion. However, Capote used a slightly different approach; he had two main ideas working simultaneously. The story began in the humble town of Holcomb. We meet the Clutter family and get a taste of what life is like in this small, quaint little Kansas town. Before any plot is laid out, though, the story jumps over to a new setting and idea: Dick and Perry. This style of writing would be like watching two movies, one on each half of the movie screen. The movie would eventually come together when the two different scenarios meet; when Dick and Perry enter Holcomb and murder the Clutter family. Capote used this approach to create a different type of suspense for the reader. Instead of using cliff-hangers between chapters, when an author would make an open-ended statement suggesting that something that of great importance is to come, Capote essentially eliminated the entire chapter idea. The book was divided into several major sections. The only divisional markers past the sections were large gaps between paragraphs to allow the reader to transition from one idea to the other. The reason Capote used this method was to create an effect of confusion, followed by understanding. Since two ideas are presented, the reader initially becomes confused as to where the story itself is heading. But as the nice town of Holcomb gets nicer, and the sick-minded ways of Dick and Per...

Canadas Copyright Law Essays - Copyright Law, File Sharing

Canada's Copyright Law Essays - Copyright Law, File Sharing Canada's Copyright Law Canada's Copyright Law Canada's copyright law is one of our hardest laws to enforce. The reason the police have so much trouble enforcing this law, is due to technology. This law is very easy to break, and once broken, it is very hard to track down violators. So although some form of a copyright law is needed, the one we have has, too many holes to be effective. There are three main ways in which the copyright law is broken in everyday life. They is audio/video tape copying, plagiarism, and software piracy. The first, and most commonly violated aspect of the copyright law, is the copying of audio tapes for oneself and friends. Thanks to the invention of dual cassette stereos, this has become very easy. You simply take an original or even another copy of a tape, as well as a blank tape. Stick them both in to the stereo and bingo you have a new tape. You also just broke the law. Along with copying audio tapes, now we can copy video tapes almost as easily. If you hook two VCR's together, they can copy from one to the other. You could rent a movie form the video store, copy and return it, with no one the wiser. The problem with copying video and audio tapes is that for every copy you make the recording artist, the actors, producers and everyone else who collect royalties from the tapes lose money. If the companies start to lose money, they raise prices. Thus a vicious circle begins. As prices go up, fewer people buy original copies. If less people buy the original cassettes prices will once again rise. Another major form of piracy is plagiarism. The stealing of someone elses ideas or work. The biggest category of people who fall into here are students. Very often a student when doing a research paper will "accidently" forget to footnote his work. By "forgetting" to give the author credit, the student has claimed the work as his own. Another reason students may copy someone else's work is to sound more sophisticated hoping that if they use someone elses words it will sound better than their own. Generally, this provides an easy way for a teacher or the police to catch them. Teachers also plagiarize rather frequently. Very often a teacher will photocopy several pages from a book, in order to save the students the expense of having to buy the book for themselves. While this is a noble act by the teacher, in most cases, this is illegal. Unless the author of the book, gave consent for his/her work to be freely distributed, teachers can't copy it any more than students or anyone else can. The third category of piracy is Software Pirating. There are several forms which this can take. The most common form is very similar to audio/video cassettes. It is when someone copies a game or program from his/her computer to someone elses. As long as the two people have the same type of computer, (they both have apples or IBM's) this is a very simple process, so long as the programmer didn't put a bug into the program (a precaution they take against people copying their work). Another form of Computer Piracy is a "cracker". A cracker is someone who has an in-depth knowledge of computers and programming. He can then remove the "bug" that prevents programs from being copied. After he removes the bug he's able to distribute the software at his own discretion. This is in direct conflict with the copyright law, because the program was not meant to be copied thus the bug. It therefore becomes illegal to remove the bug. Like audio/video cassettes copying, computer games causes people to lose money. In this case, instead of it being the singer, or actors, it is the programmer, and the software companies who lose. This leads to the same vicious circle. More copies make higher prices etc.. The copyright law is hard to enforce likewise so are the penalties. If you are found in violation of breaking the copyright laws, you probably will only have to pay a fine. However, the fines can be quite substantial and depending where you are in the distribution chain (how many copies were made before yours) the fine varies, with whoever copied the original paying the most. In extreme cases, where a contract is enacted upon the purchase of the original copy like with Word Perfect, a

Reflection - Assignment Example The supply is higher than the demand due to the release of past stockpiles by the energy companies that expected prices to go higher over the years while ignoring the price decrease. In normal circumstances, the prices fall resulting in a decline in supply and an increase in demand. However, the prices of oil declined, and demand decreased while supply increased. The predictions by the government for a further decline in prices have resulted in the maintenance of the equilibrium demand by customers expecting the prices to decrease further. Energy companies want to release as much oil and its product at the current price to avoid doing so when the prices decrease further. At the moment, the forecast for future price decreases is influencing the behavior of the supply and demand of oil prices. The steady and firm dollar has also affected the demand for oil. Oil prices get measured in dollar terms, and the currency has been stable making the decrease in prices ineffective in most countries where the dollar rates supersede the change. The increased supply has also happened due to the change in technology that allows oil companies access supplies in the trapped shale-oil

Research Design and Methods - Coursework Example Research according to Jupp (2006) entails exploration, analysis, interpretation and the creation of understanding of varied phenomena which are educational in nature, and pertains a formalized and gradual occurrence of social, cultural and psychological processes. This implies that it deals with educational concerns in which there are possibilities of carrying out satisfactory investigation. Similarly, â€Å"†¦the methods which enable such satisfactory investigations and the utility of the results emanating from the investigation are important.† (Dash 1993). The theoretical questions in education result from varied concepts and social understandings of the same. For this reasons, a number of varied paradigms have been brought forward to explain the criteria depending on the methodology selected and the definitions of the concerns for the inquiry. A paradigm, according to Kuhn (1962) â€Å"†¦an integrated cluster of substantive, concepts, variables and problems attached with corresponding methodological approach and tools† (p.52). Positivism paradigm- The paradigm explores social reality and is anchored on ideas of August Conte, a French philosopher. Conte postulates that the two key aspects of observation and reason inform the understanding of human behavior. He underscores the knowledge is based on sensual experience which is obtained through experimentation and observation. His scientific method is, therefore, used by positivistic thinkers to generate knowledge. There are a number of assumptions under the positivism, which are vital in helping to understand the paradigm. However, these assumptions at some point have been considered as separate paradigms of their own. They include; the assumption of ‘Parsimony’, the assumption of ‘Empiricism’ the assumption of ‘Generality’ and the assumption of ‘Determinism’ which form the framework within which the paradigm is
