Ethnics and Heritage Destroyed George in Gloria Naylor’s Mama Day :: Gloria Naylor Mama Day Essays

Ethnics and Heritage Destroyed George in Gloria Naylor’s Mama Day It has been said before that opposites attract when it comes to love. In Gloria Naylor’s Mama Day, two people who would seemingly never end up together somehow find a way to form a relationship that eventually leads to a marriage. George and Cocoa, the two lovers featured in this book, come from backgrounds that could not be more unlike the other. How they end up falling in love is close to a miracle, but because of their huge difference in background, they bring to each other what they wish they could have in themselves. While George is a man who comes from the diverse and strictly governed big city atmosphere of New York, Ophelia is a woman who was raised on the island of Willow Springs which is inhabited by descendants of slaves and is subject to racism and disregard for normal conduct in society. New York is a place where science and facts control the decisions of life; Willow Springs has many rituals based on magic and superstition. Because the two locations are so incre dibly opposite from one another, it is difficult for George to believe in anything that Cocoa was raised on. However, in order for George to get Mama Day’s approval, he must believe and understand magic as it exists in Willow Springs both in its physical form and as a form of belief. The biggest influence of magic on the island of Willow Springs is Mama Day. A descendant of the legendary Sapphira Wade, Mama Day is said to have convinced her master to give the land that is Willow Springs to the slaves, for which she â€Å"†¦bore him seven sons in less than a thousand days, to put a dagger through his kidney and escape the hangman’ noose, laughing in a burst of flames.† (Naylor 3) The influence of Sapphira’s magic is carried over into Mama Day, as it is said that she could, â€Å"†¦walk through a lighting storm without being touched; grab a bolt of lightning in her hand; use the heat of lightning to start the kindling going under the medicine pot.† (Naylor 3) For a rational minded person like George, this and some of the other traditions can be hard to accept. One such example of George’s ideas of normal human behavior clashing with Mama Day’s occurs when Mama Day and Grandmother Abigail give the married couple a quilt made entirely of articles of clothing from past generations.

Modifications to the National School Lunch Program Essay

Introduction Recent modifications made to the National School Lunch Program menu have caused controversy all across the nation. In last year The National School Lunch program have been under scrutiny and major changes have been made to the ingredients and preparation of school lunches. The USDA reports that the all the modifications to the school lunches are focus towards improving the health of all school age children, contributing to the fight against childhood obesity and succinctly to improve the health of all children across the nation. This research would explore the history of the different federal agencies involve in the national nutritional services, the most comprehensive changes in the school nutritional environment , the old and new menus choices and how changes are impacting students (National School Lunch Program,[NSLP] 2012). Research Statement According to the Unites States Department of Agriculture Food and Nutrition Service the recent changes to the National School Lunch program have been an important aid in the fight against childhood obesity and to help change student eating habits towards a healthier approach. In the last 4 years the Senate of the United Stated has proposed different legislature changes to the National School Lunch menu allowing millions of dollars to contribute towards a healthier approach modifying what student age children are consuming during school hours. The most comprehensive changes have been oriented towards reducing fat, sugar and sodium, and including more vegetable as part of the daily school cafeteria menu (United States Department of Agriculture, [USDA] 2012). Initial Research Question How the recent changes to the national school lunch program can improve the student’s health? By analyzing the recent changes to the national school lunch program we will be able to compare some of the differences between some the new and improve school lunch menu and how these changes are impacting students across the nation. Review of literature The National School Lunch Act was a law established under the administration of President Harry Truman in 1946. The original purpose of the act was to help local farmers with surplus produce and using these foods to feed school age children. After reviewing the principles of the act, members of the senate requested the establishment of a national program that under the guidelines of the National School Lunch Act, would oversee all operations associated with school lunch meals, reason for the creation of the National School Lunch program. The National School lunch program manages one of the largest federally assisted meal programs that provides nutritionally balanced meals free or at low cost to school age children. The national school lunch program takes cash subsides and foods provided by the U.S Department of Agriculture, in return the national school lunch program must meet nutritional federal requirements and most important must offer meals free or at low cost to all student age children. According to reported statistics from the U.S Department of Agriculture the National School Lunch feeds over 30 million students each day (NSLP, 2012) There is no doubt that the student nutrition subject has been an important topic of national concern in the history of our country. In 1966, The Child Nutrition Act was a law signed by President Lyndon B Johnson, encouraged by a national concern over nutrition in school age children. The Child Nutrition Act became to be an instrument to facilitate the process of meeting nutritional needs of children under the guidelines of the National School Lunch Program. The act also helped established the school based breakfast program providing free breakfast for children in public and nonprofit schools, during the signing of this act president Johnson use a famous phrase that would change forever the futures of national school lunches â€Å"Good food is essential to good learning† (USDA, 2012) U.S Department of Agriculture is a federal funded division who is responsible to all operations in the nation pertaining to farming agriculture and food. Better known as the USDA the department not only promotes and helps farming and agriculture issues but ensures food safety across the nation. The USDA is one of the oldest federally department created by President Abraham Lincoln in 1862. The USDA oversees a vast amount of operative units in the united states including the USDA Food and Nutritional Services who major goal is to provide healthy food to families in need, the department also collaborate closely with the National School Lunch program providing foods that are of nutritional value (USDA, 2012) On December 13th, 2010 President Obama sign into a law the Healthy, Hunger –Free Act of 2010. This act was creating to combat the alarming rates of childhood obesity cases in the U.S. The now law came to update the school meals standards who reflected very little changes in nutrition in the last 15 years, the HHFK Act also had an impact on the USDA, changing the foods providing to the National School lunch program and succinctly reflecting changes in meal nutritional standards in schools across the nation. In the 2009 a review from the Institute of Medicine recommended several updates to the National School lunch menus, the review found that the school cafeteria menus were not meeting the dietary guidelines for school age children stated by the U.S Department of Agriculture Food and Nutrition Services (Healthy Hunger-Free Act, [HHFA] 2012) In 2011 the USDA proposed new regulations based on the finding of the Institute of Medicine of the United States. The process of modification of the school cafeteria menus begin slowly but steady on schools across the nation, the changes included whole grain servings on all meals; reduce saturated fat sugar and sodium, and more fresh fruit and vegetables. Elizabeth Ippel, executive director of The Academy of Global Citizenship in Chicago, talks about the important of nutrition’s â€Å"good nutrition is essential and a very integral component to effective learning†. The changes are significant and according to Mrs. Ippel the students are responding positive to the modifications (Leamy, 2012) Here’s an example of a before and after lunch menu: BeforeAfter Breaded beef patty on a white roll Baked Fish Nuggets Fruit popsicleWhole wheat roll Low fat milkMashed potatoes Broccoli Peaches Skim Milk Discussion On December 13, 2010 president Obama signed into law 111-296 the Healthy Hunger –Free Act of 2010. The act is one of the most comprehensive proposals in the school nutritional environment in over 15 years; the main goal of this law is to update school meals nutritional standards to help combat childhood obesity and help students achieve healthy eating habits. Beginning in July 2012 the new lunch meal pattern will be in effect changing what students will be consuming during lunch in the school year 2012-2013.The new proposed meal components includes key changes for children K and above, these changes requires that school lunches offer a daily variety of whole grains, fruit and vegetables. In the fruit category, each meal provided by school cafeterias must include  ½ cup of fresh, frozen or canned fruits, prepared or compound with water and not syrup.  ½ of vegetables on each meal is another requirement in the daily school lunch menus; the new regulations required a variety of vegetable groups including: dark green, red/orange, legumes, starchy and other vegetables. On the area of whole grains, breads and cereals are required on each meal as long as the food item includes more than 8 grams of grains. The act has also limit the amount of flavored milks opting for only low fat milk during meals. Calories are also under a scope view limiting the calorie ranges according to age groups. Trans-fat is banned completely from school cafeteria menus and the act has also a plan to limit sodium gradually over the next decade, to reach the goal of keeping sodium at a no more than 600 mg per meal, equal to a diet frozen meal (HHFKA, 2012). The changes in the cafeteria school menu are impacting students and teachers equally, besides of more nutritional value, the new menus now offered more quantity amounts of healthier foods, satisfying the hunger of millions of students and reflecting healthier attitudes in the classrooms. LuAnn Coenen from Appleton Central High School in Wisconsin cheers the new regulations in the cafeteria menus and states† Since the introductions of the new food program, I have noticed and enormous difference in the behavior of my students in the classroom,†Ã¢â‚¬ I can say without hesitation that it’s changed my job as principal†. It seems that less sugary foods and drinks are impacting student’s behavior. An associate professor of education at the Lehigh university conducted a study of over 2000 lunchrooms across the nations, the conclusions indicated that healthier and less sugary meals carries a calmer atmosphere in the classroom this calmer demeanor is reflects when students go back to the classrooms creating a trickling effect. Taylor a student from Appleton High commented about the changes she felt since the cafeteria menus changed â€Å"I’d say being able to concentrate better†. Susan Graham principal from Melrose Elementary in Tampa Florida confirms that her discipline referrals have decreased 50 % â€Å"We get a lot more done, I think it’s a lot more efficient work environment for all of us,† Grahams said (abcnews,2012). Berger (2005) wrote about the importance of a well balanced meal for the proper development of children’s brain development, and how school meal programs played an important rolled in children’s brain development, by providing a well balanced meal while in school children can achieve proper brain development a subsequently their ability to learn will be maximized (Berger, 2005). The changes happening in schools cafeterias might seem insignificant, but replacing extra-cheese pizza, deep fried chicken for whole wheat pizza and baked fish nuggets, represent a huge step towards making students healthy. Some modifications to the school lunch menu have happened slowly and some hidden from students, like replacing full fat cheese with a low fat mozzarella cheese in the pizzas, as well as using whole wheat bread on grill cheese sandwiches. Dr. Saira Jan a Rutgers University Professor (2006) comments on children obesity and diabetes rising numbers â€Å"Kids choose from what they are offered. They are hungry, they will eat. You can offer carrots or French fries. We have a big health-care problem. We can’t just talk about it† (Weekly Reader, 2006). Conclusion In conclusion the overall national concern over childhood obesity and the rising rate of diseases in children related to overweight issues is currently being addressed by different entities in charge of school nutrition. The National School lunch program has and will make modification on the students’ lunch menu to feed students healthier foods in the effort to fight childhood obesity. Even though there has been mixed opinions about the effectiveness of the lunch menu modifications, the HHFKA guidelines demonstrate how References About USDA. (2012).

Learning Theories Essay

This chapter takes a brief look at the two major categories of learning theories (behaviorism and constructivism), the major theorists within those categories, and the implications of those theories for the use of multimedia and communications and information technology for learning purposes. A separate section within the chapter provides a brief overview of learning based upon neuroscience and recent discoveries about the functioning of the brain. A series of links are provided to further resources on learning theory, neuroscience, and the brain. pic] Our Technological Revolution and the Implications for the Way We Learn We have all experienced a learning moment when we were so focussed or engulfed in the learning, that everything else did not matter. Candidly, the raison d’etre or motivation for our focus may have been that we had a boss or teacher breathing down our neck or an impending exam was to quantify our level of knowledge or intelligence or a particular moment neces sitated that a skill be learned very quickly. Regardless of the motivating factors for this moment of focussed learning, the experience is what psychologists Mihaly Czikszentmihalyi and Ellen Langer label in their respective theories, as moments of â€Å"optimum flow† or â€Å"mindfulness†. According to psychologist Mihaly Czikszentmihalyi, optimum flow occurs when: Alientation gives way to involvement, enjoyment replaces boredom, helplessness turns into a feeling of control, and psychic energy works to reinforce the sense of self, instead of being lost in the service of external goals. (Czikszentmihalyi, 1990, p. 9) Replicating such moments of optimum flow is the job of educators regardless of the domain, whether it be school, the workplace in job training, or the military, etc. Moreover, certain learning theorists are advocating the greater use of technology, namely computers, in learning situations because they see enormous potential of computer technology to replicate these optimum moments of flow. Learning is a personal act. We each place our own personal stamp on how we learn, what we learn and when we learn. We in effect have our own learning style. Howard Gardner’s theory of multiple intelligences which acknowledges learning as an holistic experience is, at present, one of the most well known descriptors of human cognitive profiles. The act of learning is paradoxical in nature. It can at times appear to be a very simple act. So simple, that we do not question its presence in how we go about our daily activities, for it is natural to our existence as learning organisms. Yet, when we encounter difficulties in learning something, we no longer take the learning process for granted. It is only then that our metacognition or awareness of how we learn is heightened. Learning is taken for granted as a natural process. As simple a process it may seem, the root of understanding how we learn is not as straight forward. The existence of numerous definitions and theories of learning attest to the complexity of this process. A random sampling of any educational psychology text will illustrate the variance in views to what exactly is learning and how we do learn. In Educational Psychology: An Introduction, for example, the authors write, â€Å"Learning implies a change in the individual as a result of some intervention. It may be viewed as an outcome or as a process. (Belkin and Gray, 1977, p. 211) While this definition reflects a behaviorist view of learning, for it equates learning as an outcome, it is a starting point for the authors to expand their description of learning into many other realms, namely the different theories of learning. They in effect, devote a whole chapter of their text just to describe the many ways of defining learning. While it may seem somewhat premature to evaluate the aforementioned definition of learning and to equate it with a specific theory, it is important to recognize that â€Å"intervention† in the learning process can imply many different things. The degree of intervention, by who or what and how, are the defining factors of a learning theory. These factors help distinguish the many different theories. As you will see these theories are not stagnant. They are evolving and changing as we discover new ways of viewing human cognition. â€Å"The mechanistic model of the mind of the behavior era has given way to the logical-computational model favored by artificial intelligence and cognitive science theorists† (McLellan, 1996, p. 6). Don Tapscott, in his book Growing Up Digital: The Rise of the Net Generation, argues that we are now in a digital era of learning. According to Tapscott, a transformation in learning is taking place from what he labels â€Å"broadcast† learning to â€Å"interactive† learning. No longer are today’s generation of learners satisfied in being the passive recipients of the traditional teaching process, rather, they want to discover it for themselves by becoming interactive with the learning. The net generation children using GlobaLearn [a web site], are beginning to process information and learn differently than the boomers before them. New media tools offer great promise for a new model of learning – one based on discovery and participation. (Tapscott, 1998, p. 127) Tapscott’s thesis that the â€Å"technological revolution† is permeating every aspect of our lives forces us to examine the use of computer technology as learning devices. Such rapid social, economic and general lifestyle change, due in essence to the technological revolution, begs the question – based on learning theory, why does the use of computers as a â€Å"learning† tool make sense? This chapter will answer this question by profiling the many learning theories. [pic] The Spectrum of Learning Theories As a review of the literature of learning theories will illustrate there are many labels being used to describe the many theories. Moreover, there are many theorists associated with each approach. A categorization of these labels and theorists will help in understanding these fundamental theories. The spectrum of learning theories consists of many approaches or ways of explaining how humans learn. A description of each of these theories will suffice in providing you with enough knowledge to critically examine the use of computer technology as a learning device. The resume of each theory will consist of: †¢ the associated names of the theory †¢ a description of the theory †¢ theorists associated with the theory †¢ hyperlinks on the World Wide Web Diagram #1: The two extremes Behaviorism   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚     Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚     Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚     Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Constructivism The extremes of this learning theory spectrum are represented by respectively, the Behaviorist and Constructivist theories of learning. As theories trying to explain the same thing, they are bipolar based on their respective views of how knowledge is acquired and the intervention of tools of learning (teachers or instructors). As a context to better understand all of the theories of learning presented in this chapter, examine these two extremes first and then place the remaining theories onto the spectrum. [pic] Behaviorism The Associated Names of this Theory: Behaviorism labelled as a teaching approach is often referred to as directed instruction. As you compare this theory with the Constructivist view of learning, this label will become self-evident. Also in contrast to Constructivism, it has been labelled an objectivist theory of learning. Theorists associated with Behaviorism: J. B Watson E. L Thorndike B. F Skinner A Description of Behaviorism: The concern or emphasis of Behaviorism is observable indicators that learning is taking place. Contrasting this view of learning is the emphasis of cognitive psychologists who equate learning with the mental processes of the mind. Behaviorists do not deny the existence of these mental processes. In fact, they acknowledge their existence as an unobservable indication of learning. The focus of Behaviorism is on the conditioning of observable human behavior. J. B Watson, the father of Behaviorism, defined learning as a sequence of stimulus and response actions in observable cause and effect relationships. The behaviorists’ example of classical conditioning demonstrates the process whereby a human learns to respond to a neutral stimulus in such a manner that would normally be associated with an unconditioned stimulus. The supporting example often cited with classical conditioning is the case of Pavlov’s dog. The focus of Pavlov’s experiment was the digestive process in animals. In conducting the experiment, Pavlov noticed that the dog would salivate (response), upon hearing the ringing of a bell. This occurred because the dog had learned to associate its unconditional stimuli (normally feeding), with the neutral stimuli of the bell ringing simultaneously with the feeding process. Watson, believed that the stimuli that humans receive may be generated internally (for example hunger), or externally (for example, a loud noise). B. F. Skinner expanded on the foundation of Behaviorism, established by Watson, and on the work of Edward Thorndike, by focussing on operant conditioning. According to Skinner, voluntary or automatic behavior is either strengthened or weakened by the immediate presence of a reward or a punishment. â€Å"The learning principle behind operant conditioning is that new learning occurs as a result of positive reinforcement, and old patterns are abandoned as a result of negative reinforcement. † (Belkin and Gray, 1977, p. 9) In his book entitled, The Technology of Teaching, Skinner wrote: The application of operant conditioning to education is simple and direct. Teaching is the arrangement of contingencies of reinforcement under which students learn. They learn without teaching in their natural environments, but teachers arrange special contingencies which expedite learning, hastening the appearance of behavior which would otherwise be acquired slowly or making sure of the appearanc e of behavior which otherwise never occur. (Skinner, 1968, p. 4) Skinner believed that more complex learning could be achieved by this process of contingencies and reinforcement â€Å"†¦ through successive stages in the shaping process, the contingencies of reinforcement being changed progressively in the direction of the required behavior. † (Skinner, 1968, p. 10) Applying the theoretical principles of Behaviorism to learning environments, it is easy to recognize that we have many â€Å"behaviorist artifacts† in our learning world. A dissection of the traditional teaching approaches used for years would reveal the powerful influence that Behaviorists have had on learning. The concept of directed instruction, whereby a teacher is providing the knowledge to the students either directly or through the set up of â€Å"contingencies†, is an excellent example of the Behaviorist model of learning. The use of exams to measure observable behavior of learning, the use of rewards and punishments in our school systems, and the breaking down of the instruction process into â€Å"conditions of learning† (as developed by Robert Gagne), are all further examples of the Behaviorist influence. With the advent of the computer in school, C. A. I. , or computer-assisted instruction has become a prominent tool for teaching, because from a Behaviorist perspective, it is an effective way of learning. CAI uses the drill and practice approach to learning new concepts or skills. The question acting as the stimulus, elicits a response from the user. Based on the response a reward may be provided. The â€Å"contingencies† of learning are translated into different levels of the program. Rewarding the user to a different level for correct responses follows exactly the approach of operant conditioning. Educators have espoused CAI as an effective teaching approach because it allows for self-paced instruction and it liberates them from the direct instruction of all their students so as to focus on those students with particular needs.

It however, may be associated with cognitive psychology because as a theory of learning it focuses on a learner’s ability to mentally construct meaning of their own environment and to create their own learning. As a teaching practice it is associated with different degrees of non-directed learning. The term constructivsm is linked to Cognitive and Social Constructivsm. Theorists associated with Constuctivism: John Dewey Lev Vygotsky Jean Piaget Jerome Bruner Seymour Papert Mitchell Resnick A Description of Constructivism: The merits of Behaviorist learning theory and of their teaching practices are well documented. They have served well in teaching a growing North American population over the past six decades. Behavioral learning theory manifested itself in creating a systematic approach to teaching. Robert Gagne and Leslie Briggs, in their book, Principles of Instructional Design, combined Behaviorist principles of learning with a cognitive theory of learning named Information-Processing. The focus of the latter theory in this combination was of the internal processing that occurred during a learning moment. The design of instruction must be undertaken with suitable attention to the conditions under which learning occurs. With reference to the learner, learning conditions are both external and internal. These conditions are in turn dependent upon what is being learned. How can these basic ideas be used to design instruction ? How can they be applied to the design of single lessons, of courses, and of entire systems of instructions ? (Gagne and Briggs, 1974, p. 14) Gagne and Briggs’ principles of instructional design broke down the teaching process into a systematic process of nine steps. It is in effect, this type of systematic approach to teaching that acted as the catalyst for the creation of another view of the way humans learn. Behaviorist learning theory had served its purpose and its approach and goals were becoming outdated according to Constructivists like Seymour Papert. Constructivist learning theory sought to improve on what Behaviorist learning theory had already established by focussing on the motivation and ability for humans to construct learning for themselves. It viewed Behaviorism as being too teacher centered and directed. Constructivists regarded the educational system as a process of matching skill objectives with test items. It was void of meaningful learning. They also saw the teaching process focus too much on individual work rather than on group work. The final critique of Behaviorist learning theory from the Constructivist perspective helped define the core of Constructivism. To imply that knowledge is separate to the human mind and that it must be transferred to the learner in a teacher centered approach fundamentally was counter to the Constructivist theory of learning. Constructivists believe that all humans have the ability to construct knowledge in their own minds through a process of discovery and problem-solving. The extent to which this process can take place naturally, without structure and teaching is the defining factor amongst those who advocate this learning theory. Jean Piaget, a Swiss psychologist, observed human development as progressive stages of cognitive development. His four stages, which commence at infancy and progress into adulthood, characterize the cognitive abilities necessary at each stage to construct meaning of ones environment. Seymour Papert, psychologist and contemporary critique of Behaviorist teaching methods, writes in his book, The Children’s Machine: Thus, constructionism, my personal reconstruction of constructivism has as its main feature the fact that it looks more closely than other educational -isms at the idea of mental construction. It attaches special importance to the role of constructions in the world as a support for those in the head, thereby becoming less of a purely mentalist doctrine. (Papert, 1993, p. 42) As the inventor of LOGO, the programming tool for children, Papert too believed that children as learners have a natural curiosity to construct meaning of their world. The educational system as Papert saw it was too structured and it stifled this natural curiosity. The means by which children were being taught relegated them to a role of passive recipients of the teaching hence, they were not motivated to construct any learning for themselves. Learning according to Constructiv ists is a question of motivating an individual to attach new meaning to past cognitive experiences. According to Papert: It [constuctivsm] does not call in question the value of instruction as such. That would be silly: Even the statement (endorsed if not originated by Piaget) that every act of teaching deprives the child of an opportunity for discovery is not a categorical imperative against teaching, but a paradoxically expressed reminder to keep it in check. The constructionist attitude to teaching is not at all dismissive because it is minimalist – the goal is to teach in such a way as to produce the most learning for the least teaching. Of course, this cannot be achieved simply by reducing the quantity of teaching while leaving everything unchanged. The principle other necessary change parallels an African proverb: If a man is hungry you can give him a fish, but it is better to give him a line and teach him to catch fish himself. (Papert, 1993, p. 139) Papert’s desire to have children become motivated learners, critical thinkers, problem-solvers and metacognitionists is to be achieved through educational reform that provides the learner with the necessary tools to participate and to take ownership of the learning process. According to Papert, the computer is the appropriate tool to achieve such desired educational reform. These desired objectives of Papert and others who share the Constructivist view of learning are coming closer to reality as more people discover the power of computer technology. From Donald Tapscott’s perspective, Papert’s desired reality is happening now, as a paradigm shift to more interactive learning due to the exploitation of the digital media is taking place in our learning institutions. Tapscott cites eight shifts in learning today: †¢ From linear to hypermedia. †¢ From instruction to construction and discovery. †¢ From teacher-centered to learner-centered education. †¢ From absorbing material to learning how to navigate and how to learn. †¢ From school to lifelong learning. †¢ From one-size-fits-all to customized learning. †¢ From learning as torture as learning as fun. †¢ From the teacher as transmitter to the teacher as facilitator.

Other learning theories equated with cognitive psychology are: Information-Processing theory, Scaffolding theory (associated with the Russian philosopher Lev Vygotsky) and Brain-based learning theory (associated with neuroscientists such as Marian Diamond and Robert Sylwester and educator Susan Kovalik). Information-Processing theory regards human learning as being analogous to a computer and its ability to store memory. As humans we process information initially with our senses. This information is either processed into our short term memory or it is lost. If this information is used and practised it is only then put into long term memory. Lev Vygotsky thought that our cognitive development was directly related to our social development. The culture we live in influences our social and cognitive development according to Vygotsky. He further recognized the differences of how the world is seen by children and by adults. Vygotsky labelled this difference in cognitive ability as the â€Å"zone of proximal development†. The job of educators was to identify this zone and to find out where the child was situated in this zone and build upon their specific level through a â€Å"scaffolding† process. Building from what the learner knows is in essence, anchoring the learning on past experience. Such anchoring is fundamental to Constructivist theory of learning. Computer technology is viewed by Seymour Papert as an excellent means to anchoring learning to meaningful experiences. The complexity of understanding how humans learn is reflective of our complexity as biological, social and cognitive animals. Many theories exist, all focussing on different aspects of our make-up as humans. Each theory is an attempt to explain how we learn, act and behave: Sigmund Freud focussed on our sub-conscious, Skinner on our observable behavior, cognitive psychologists on our mental processes, humanistic psychology on our social and interpersonal development. Howard Gardner took a more holistic approach in describing our cognitive profiles. His classification of human intellectual ability into seven intelligences incorporates many aspects of psychology to define the cognitive behavior of humans. Before moving on to Multiple Intelligences , refer to the following hyperlinks for information on other learning theories. http://mse. byu. edu/ipt301/jordan/learning. html [pic] Theory of Multiple Intelligences: Human intelligence should not be equated solely with linguistic or logical-mathematical intelligence alone, according to Howard Gardner. As the author of a new way of looking at human intelligences, Gardner, a Harvard professor, identified a total of seven different intelligences that humans may possess. His list includes: †¢ Linguistic intelligence †¢ Logical-mathematical intelligence †¢ Spatial intelligence †¢ Musical intelligence †¢ Bodily-kinesthetic †¢ Interpersonal intelligence †¢ Intrapersonal intelligence Gardner is working on more intelligences that qualify as cognitive processes: â€Å"Multiple intelligences theory, on the other hand, pluralizes the traditional concept†(Gardner, 1993, p. 15) Gardner’s fascination with human intelligence and how the brain works was started with an investigation of people who had experienced brain damage of some sort. He recognized that not all abilities, whether cognitive or motor-sensory, were eliminated from the individual’s repertoire despite having endured some form of brain damage. Gardner hypothesized that we possess more than one form of intelligence. The theory of multiple intelligences provides a more holistic view of the intelligence of humans. Gardner advocates that we may all attempt to develop each of these intelligences to our optimum level. However, we may be more adept in only certain of these intelligences. We may however, aspire through practice and development to improve in the remaining intelligences. The use of technology appeals to this view of intelligence in that Gardner’s theory acknowledges that cognition is not a linear process. The computer as a learning tool has enormous potential in developing the different forms of intelligences of Gardner’s theory.

Learning is the process by which we receive and process sensory data, encode such data as memories within the neural structures of our brain, and retrieve those memories for subsequent use. The variety of information stored within such memories is enormous, including such items as: how to control your sphincter muscle until a socially appropriate occasion, how to identify mommy in a crowd, how to ride a bicycle, what is the shortest path to grandmother’s house without going near the lair of the wolf, what is the tune for Beethoven’s Ode to Joy, and what a philosopher means when she says â€Å"The cat is on the mat. All learning takes place within the brain, and as our understanding of the underlying structures and processes of the brain increases we can begin to apply that knowledge to improve our construction of learning environments. Our ability to describe and understand the basic processes by which our brain learns has been enhanced by recent technological developments and by the accumulation of long-term studies in human and animal populations. Of particular benefit has been the development of brain-imaging techniques that allow us to observe the operation of normal human brains during the performance of a variety of tasks. Magnetic Resonance Imaging (MRI) and similar technologies have allowed researchers to map neural activity during sensory data processing and monitor the transfer of information into long-term memory. Researchers have also made great strides in determining the basic mechanisms that underlie the transmission of information within the brain. Such research on brain structure, neural transmitters, and the process by which memories are stored and retrieved have allowed the development of neuro-physiological models of learning. Although neuroscience has provided us with an increasingly rich and accurate descriptive theory of learning within the brain, we still need prescriptive theories of how to maximize the efficiency and capacity of human learning. To some extent all learning theories are prescriptive and seek to minimize the time required to transfer information into memory and maximize the efficiency of retrieving that information. Our current knowledge of the brain, and our speculations regarding the evolutionary function of learning, should assist such prescriptive theories in designing learning environments that provide for maximum learning efficiency. In particular, prescriptive theories informed by our current knowledge of neuroscience should allow us to evaluate the role of multimedia in learning environments. We should also be able to maximize the impact of multimedia in such environments through application of learning theories and our knowledge of the human brain. Learning environments should not be construed simply as the traditional formal classroom within the context of institutionalized public education. Such environments occur within the workplace, the home, and other social institutions as communication and information technology continues to penetrate Western society. We should also be aware that the use of multimedia will have an impact upon the development of the human brain, particularly when such techniques are used with children and adolescents whose brains are still developing and maturing. [pic] The Brain The three-pound universe that is our brain consists of more than 100 billion neurons and the associated structures that organize, nourish, and protect their functioning. Each neuron may have between 5,000 and 50,000 connections to other neurons, forming a dense connective mat that allows the storage of enormous amounts of information. It is important to remember that structures within the brain continue to develop until late adolescence and that neurons will continue to grow connections to other neurons throughout adult life. [pic] Brain Structures The diagram above shows four basic structures in the brain that are important for bodily functions and for learning and memory. The brain stem is primarily concerned with basic survival functions and the regulation of body systems. The cerebellum is involved in the performance of automatic movement patterns (walking, running, touch-typing, and other physical skills that can become part of automatic procedural memory). The limbic system is responsible for the processing of short-term memory into long-term memory as well as the generation and regulation of emotions. The cerebral cortex is the area of the brain in which sensory data is received and analyzed, decisions are made, and behavioral responses are activated. Information is received from the major sensory organs of the body: eyes, ears, nose, tongue, and skin; and is held briefly in sensory memory. The further processing of that information appears to be dependent upon the state of emotional arousal of the brain and the utility of such information for potential survival. Long-term memories are generated through the growth and spread of neural connections between those modular structures that contain the memory (Sylwester, 1995, pp. 89-90). The more often such structures are activated and the stronger the connections become to associated structures, the more easily such memories are retrieved and used by the brain in decision making and conscious thought. To some extent the driving forces behind the way our brain processes sensory input and makes decisions are the survival imperatives that accompanied human physical and cultural evolution. Our brains reflect the importance that survival places upon evaluating potential threat situations, making a quick response, and focusing all body resources on support of those functions that may lead to continued survival. In high-threat situations the focus of the brain will be almost exclusively upon what is identified as the potential threat while the body shuts down relatively unimportant systems to concentrate on those involved in the fight-or-flight response. Low-threat situations allow the brain to sample and evaluate a broader spectrum of sensory input and to analyze such input for future use. Thus a large looming shadow in the cave mouth tends to generate fear, prompting the body to shut down digestion, pump more adrenaline, and prepare the cerebellum to handle the process of running while the cerebral cortex looks for places to hide or make a stand. Strong negative emotion tends to evoke the fight-or-flight physiological and mental responses that shut down high-level cognition. A premium should therefor be placed upon the reduction of those factors within a learning environment that give rise to negative emotions. At the same time, sensory input that does not receive attention is not available for processing through short-term into long-term memory. Clearly a balance must be struck between too much and too little stimulation in learning situations. Some stimulation and motivation is necessary for the learner to pay attention to the data that they are required to learn; on the other hand too much stimulation (particularly in a negative context) is liable to create anger or fear as an emotional response, either of which can serve to reduce the amount of learning carried out within the environment. It appears that the limbic system plays an important part in the process of storing information as long-term memories. Those activities that provide an emotionally supportive environment may well have a positive effect upon the processing of information into long-term storage and subsequent retrieval of those memories. Group activities, co-operative learning, role-playing, and simulations tend to provide emotional support and emotional context for learning. Retrieval of long-term memories is enhanced when a large number of connections have been established between the neural modules that store such memories. To some extent our growing knowledge about the organization of the brain tends to support those theories of learning that can generally be labeled as constructivist. That is, situated knowledge that is connected to a large number of other memories is more apt to be recalled than is unconnected knowledge that has been learned by rote. Because the process of creating connections between ideas and memories is essentially carried out through a process of rehearsal and review, learners should be encouraged to review knowledge that is being learned and attempt to build connections to that knowledge that is already easily retrieved from long-term memory. Such cognitive tools as narration, story-telling, constructing metaphors, and making comparisons are strategies that help to build and maintain connections. The construction of knowledge is essentially the growing of connections between the neural modules that contain individual memories. [pic] Implications for Learning Theory If the apparent symmetry between contemporary brain-based learning theories and constructivism is accurate, then basic guiding principles of constructivism should be used in designing learning environments. These principles include: 1. Learning is a search for meaning. Therefore, learning must start with the issues around which students are actively trying to construct meaning. 2. Meaning requires understanding wholes as well as parts. Parts must be understood in the context of wholes. Therefore the learning process focuses on primary concepts, not isolated facts. 3. In order to teach well, we must understand the mental models that students use to understand the world, and the assumptions that support those models. 4. The purpose of learning is to construct one’s own meaning, not to have the â€Å"right† answers by repeating someone else’s meaning. Learning is inherently inter-disciplinary, and the only valuable assessment of learning is assessment that is part of the learning process and that provides students with information on the quality of their learning. (On Purpose Associates, 1998b) Such learning environments should also be designed around the ideas that come forward from brain-based learning. That is, they should employ the three instructional techniques associated with brain-based learning: â€Å"orchestrated immersion, where learning environments are created that fully immerse students in a learning experience; relaxed alertness, where an effort is made to eliminate fear while maintaining a highly challenging environment; and active processing, where the learner consolidates and internalizes information by actively processing it† (On Purpose Associates, 1998a). Learning environments constructed with these principles in mind will tend to be organized around thematic units featuring knowledge in depth and the exploration of projects that have real meaning for the participating learners. [pic] Implications for Multimedia How should we then use multimedia presentations of information to effectively learn in the context of current brain-based learning theory? The communications and information technology that constitutes contemporary multimedia platforms has some significant advantages in creating a learning environment, but there are some pitfalls that must be accounted for as part of the learning process. Multimedia, at its best, allows us to bring the real world to the learner through the use of sound and video. Such connection to the real world should serve as a factor in motivating students, and as a factor in providing them with additional connections to other knowledge structures. At the same time, multimedia allows students to experience information through multiple modes of presentation. Such multi-modal learning should help to build connections within the learner’s brain if only because multiple modes of reception will engage different areas of the learner’s brain. Contemporary multimedia platforms allow a greater degree of learner control and more freedom for the learner to undertake self-directed exploration of the material. Such self-directed learning is likely to be more meaningful and more connected to existing knowledge structures within the learner’s brain. Therefore, we should see advantages for learning programs that include multimedia presentations. Learners should also gain from the possibility of self-paced instruction based upon contemporary multimedia learning technology. Whenever possible, immediate feedback should be built into a multimedia program to assist students in forming correct connections prior to reinforcing connections between new and old information incorporated within existing knowledge structures. Designers of multimedia instructional packages should take comfort in the strengths of multimedia, but they should also be aware of potential problems in using multimedia with learners. Although current multimedia technology allows excellent presentation in both video and audio modes, and provides some tactile feedback through the use of keyboards, there is little to offer students who need tactile experience ? multimedia is essentially a bimodal presentation strategy unless additional work is done to prepare material for students. Even the best multimedia programs cannot provide the total stimulation that natural environments provide? we have yet to incorporate smell or taste into such presentations, and tactile sensations are still limited. More importantly, there is a clear danger that multimedia programs may be used to substitute for interaction with other learners. We should not be seduced by technical virtuosity or cutting-edge visual and aural effects, there is still a need for human interaction and emotional support. Above all else, we should beware of the tendency to substitute passive learning for active learning. Multimedia provides significant advantages in presenting information to learners, particularly if sufficient resources have been invested to create presentations that make full use of current technology. Presentation of information, no matter how technically sophisticated, is not enough; learners must interact with content to construct their own meanings and integrate new knowledge into the dense web of neural connections that is mind and memory.

St. Johns River, North Florida

The St. Johns I have had many experiences with the St. Johns River in my life. For as long as I can remember I have lived less than a mile from this river. Every activity from boating, to canoeing, or fishing I have done in the river, and every time the water has seemed clean. Over the years the St. Johns River has acquired a bad reputation for being nasty or dangerous. Anything from flesh eating bacteria from algal blooms to bull sharks have been rumored to be lurking in its waters. Though some of these rumors are true and some of them are false, one will not die upon touching the water. However, the St.Johns does need some extra attention based on tests, past and current programs, and the fish population. Many tests performed on the river reflect that the water is relatively clean. State officials over Volusia and Seminole counties have noticed that there is the potential for a water shortage in the next couple years due to population increases. If nothing is done, the ground water in this area will run out. A plan is being proposed to use surface water from the St. Johns River to supplement the ground water. State officials believe they can filter the water from the St. Johns of bacteria and use this water for drinking water. Ann Givens) The fact that the state is considering using the water in the St. Johns for drinking water shows that the water quality is good. If there were severe algal blooms, the state would not consider trying to filter the water. Many tests performed on the river are in response to the paper mills present on the river. There is one mill in particular addressed on Rice Creek outside of Palatka. The waste water from these paper mills is dumped from pipes into the river. Ten years ago these mills were forced to upgrade their equipment due to a toxin being released called Dioxin.Dioxin is chemical that can cause cancer produced by the chlorine reactions in the mill. The older equipment was believed to be allowing this toxin to flow into the St. Johns River. Two years ago another test was done on the Rice Creek and traces of Dioxin are still present. The general belief is that Dioxin has remained in creek residue. (Patterson, S. ) Tests similar to this are done throughout the river. The residue remaining from the Dioxin is only present in Rice Creek and is not present throughout the water system. This effort to control the Dioxin shows progress.Scientists identified that the Dioxin was present and the source and took severe action to eliminate the expansion of Dioxin. Though this effort was necessary and applauded, efforts now need to be made toward eliminating the remaining residue and removing Dioxin from the river completely. Many programs and funds have been devoted to improving the water of the St. Johns River. A major act proposed in the 1970’s was the Clean Water Act of 1972. The Clean Water Act forced Floridians to find bodies of water that are impaired due to higher nitrogen levels.Once established, the state had to institute total maximum daily loads for each of these bodies of water. The total maximum daily load (TMDL) is established â€Å"based on the maximum amount of pollutant that the water body can assimilate without exceeding water quality standards. †( Lynette, M. ) This act made progress in reducing the level of nitrogen being added in the river. Though this act passed in 1972 the problem is still present. Over the years, Florida has seen 80,000 acres of its wetlands developed. (Littlepage, R. L. This results in less water present in the system and more nitrogen in the ground water from people fertilizing their yards. If the population in central Florida continues to expand and the wetlands continue to disappear, the presence of algal blooms and the reduction of the fish population will never stop. The water removed and nitrogen added will continue to create a steeper imbalance. Also with development, central Florida is trying to take water from the St. Johns f or drinking water for their excessively large population.This will just make the nitrogen to water imbalance even steeper. Rules and regulations need to ether be put on wetlands destruction, fertilizer use, and population limits in central Florida based on how many people their water supply can sustain. In 2006 a large sum of money was devoted to the effort of preserving the St. Johns River. Twenty seven million dollars was devoted to reducing the amount of nutrients, like nitrogen, entering the river and increasing standards for companies like Jacksonville Electrical Authority (JEA) who dump into the St. Johns River.The mayor’s office made JEA increase its standards for dumping waste water into the river and expand its programs for reusing water. This would reduce the amount of waste water dumped in the river and reduce the amount of harmful chemicals that enter the river from the JEA plant. (Littlepage, R. L. ) A major concern in the St. Johns is the fish population. The la rgest pollutant in the river is nitrogen from excess fertilizers that flow into the groundwater and into the river. The plant life of the river feed on this nitrogen. More nitrogen then leads to more plants.As the plant population increases problems such as algal blooms on the surface of the water occur. With the algal bloom situation the lower section of the water is blocked or partially blocked from sunlight. This leads to less plant life on the floor of the river and thus less oxygen in the water. With the lack of oxygen the fish population will plummet soon after. In 1994, an experienced bass angler by the name of Doug Gilley did an interview for the Orlando Sentinel. In this article he provided his professional insight on the change destruction of the bass population from 1984 to 1994.Ten years before this article was written, it would be no surprise for him to catch â€Å"10, 20 or even 50 fish in a day. † (Wilson, D) Doug was not the only one who had noticed this drast ic decrease in the bass population. State fisheries agreed with him. They have noticed that the â€Å"large bass almost have disappeared from the river and that the number of mid-sized bass are declining. † (Wilson, D. ) I personally have noticed the decline of fish from the river. My brother and I are avid fisherman and enjoy fishing for just about anything.We lived a quarter of a mile from the river so often we would take my grandfather’s bass boat and go fishing in the river. However, no matter how much we prepared, we would never catch more than maybe one or two fish. This change shows how all the different pollutants are having a large impact on the fish population and if action is not taken species like the largemouth bass could be eliminated from the river. Fishing is not the only recreational activity that takes place in the St. Johns. Activities such as skiing and tubing take place daily during the spring and summer months.These are essential for Floridaâ€⠄¢s economy. When people are going out in their boats, many aspects of the economy are helped. People must buy gas for their boat, food to eat while they are on the boat, and other items. This also attracts tourists. By my house at a local marina, every summer they hosted a wakeboard camp for people to come learn how to wake board. Hundreds of people would come to learn how to wakeboard and have fun in the water. These people bought many things during their stay thus boosting the Florida economy. However, if the water is not maintained and kept clean, events like these cannot occur.Tourists would not be willing to get in the water and would take their business elsewhere thus restricting north Florida’s economy. In closing, the St. Johns River is not dangerous as far swimming and boating are concerned but there are pollutants being dumped into the river that need to be addressed or eliminated. If nothing is done, based on tests done on the water, past and current programs, and the fish population the wildlife, the quality of the St. Johns will continue to plummet. The river damage will become impossible to fix and potentially impossible to swim or use for any recreation.The repercussions of this would be exponential. Water shortages could occur along with Jacksonville losing its appeal as somewhere to live. Citations Page Ann Givens of The Sentinel Staff. (2001, Feb 16).

My Sociology Paper Essay

High speed car chases are one of the most highlighted broadcasts in television today. Using aerial shots to give viewers a better preview of the scene, the media even interrupts regular programs to bring special reports of these fast-moving headlines. The media launches multiple fleets of helicopters (which main purpose for existence is to watch and update traffic conditions in real-time) to follow these car chases until they end either losing the perpetrator or catching them; sometimes without casualties, and sometimes with multiple damages added to the casualties of innocent bystanders. Throughout modern history, television entertainment and racing has been closely related spawning many different events to the fore such as F-1 and NASCAR racing. Many would owe their popularity to the adrenalin rush these high-performance vehicles incite in their viewers, and likely, this reason also trickles down to high speed car chases, which are growing more prominent over the recent years. More to this, the growing debate on whether the police are to blame for the chases they give to problematic drivers incites more people to add to the fray, as well the intrigue surrounding the matter of why the driver didn’t pull over in the first place. This and many other factors have made car chases a media staple – something that viewers will look forward to watching (Settgast 2008). With death tolls, injuries and intrigue surrounding these special broadcasts, editorials appear criticizing the police for actually giving chase and not letting these vigilantes go on their way. But even bombarded with criticisms, the police don’t give up the chase and continue with the pursuit of these reckless drivers (Sowell 2007). There are many reasons as to why police officers give chase to reckless drivers. As a matter of fact, courts have continuously investigated on whether the chases are necessary and the use of force by the police to stop them are justified such as the case of â€Å"Scott v. Harris† where a police rammed the car of a 19-year old, rendering him quadriplegic (Settgast 2008). This, and other cases has set the media hogging up more airtime for police chases because of several reasons; one of which is because police car chases, by themselves, already have the star factor to attract viewers. The media exposition of the high speed car chases, from the thrill of the chase to the dramatic (or non-dramatic) ending, have always had viewers finding themselves hooked on the screen once it turns on. The interpretative model is one of the models that explain viewer behavior on media. As Giddens describes, the model views that the â€Å"audience has a powerful role†¦The interpretative model views audience response as shaping the media though its engagement or rejection of its output† (2000). This means that the media is actually beholden to their viewers if only because of the competition they have with other television media companies, and their desire to increase their rating. With more viewers attuned to them, the higher their ratings would become, therefore they would attract more sponsors and more sources of income. In this regard, the media’s duty is to please their viewers also because it is a necessity for them in order to survive. Because of the wide acceptance by the public of high speed car chases as a from of entertainment, the media has jumped at the chance to improve their ratings by showing these through â€Å"special live reports†. One of the most famous and iconic showcase of this is the car chase involving O. J. Simpson in 1994 where â€Å"For two hours, 95 million Americans ignored the sixth game of the professional basketball finals in the East and the sunset in the West to stare at the tube as a white Ford Bronco drove sedately along one strand and then another of L.  A. ‘s web of freeways† (Reuven 1994). With this kind of attention the media gets from the public and the media’s response to getting more of this on television, it is evident that audiences now have the freedom to watch what they want (Chinni 2005) . We see that the public’s attention to high speed car chases actually seems like a glorification of the crime, especially as they are portrayed in movies and are used to be redeeming factors no matter how disastrous a movie turns out to be (Dean 1993). Another side to the story is that high speed car chases sometimes involve violence and some people hope there would be some action if only for reasons of entertainment. Some even consider high speed car chases, themselves to be violence on its own as it capitalizes on aggressive behavior. There are multiple evidences that point to the fact that violence is a form of entertainment is multiple and that the media jump on the chance to be in the action increase their ratings. However, media influence on people is a part of the deal and cannot be ignored. Exposure to almost anything the media imparts creates a permissive atmosphere for aggressive behavior which translates to action over time. Whether the effects are little or the effects are large (in the midst of the ongoing debate of the extent of media influence over its viewers), the bottom line is with the media’s emphasis on aggressive behavior (such as high speed car chases) it is important to note that there is a high likelihood of people imitating the high speed car chases themselves due to drug or alcoholic influences (Felson 1996). In this case, not only do the people dictate what the media will showcase and highlight in their programs, but the media also influences how people perceive the world and influence their choices and preferences of shows and broadcasts. Also of considerable notice is the fact that people, devoid of the factors that control their inhibitions, are susceptible to be the perpetuators of high speed car chases themselves as can be read from the study. Such factors that contribute to the removal of inhibitions include the influences of drugs, alcohol, and others. As such, the likelihood that people would be experiencing and trying out for themselves the â€Å"thrill† of high speed car chases is high. We see that these two factors together (public influence on media and media influence on the public), creates a vicious cycle of the continuous glorification of aggressive behavior, such as high speed car chases.  This glorification is, first of all, seen in how people are attracted like moths to a flame by the star factor of this broadcast/report. Owing to the high speed car chases’ innate ability to arouse emotions (such experiences can also be found in pro-sporting events such as football and NASCAR racing), people become more and more addicted to watching them, and in the end, spurring the media to feature more whenever these incidences take place. Moreover, high speed chases in Hollywood add to the thrill effect of this dangerous pursuit making them more palatable to their viewers. Secondly, the glorification comes in the form of media sensationalizing these high speed car chases by making it seem more exciting than it actually is like adding the words â€Å"special† and other effects to these reports. Also, the media takes these high speed chases to the editorial newsroom to spur more of the excitement even if it only lasts for a few days. In essence, the thrill effect of high speed car chases and the sensationalism by the media glorifies this dangerous sport. Coupled with the emotion-evoking nature of high speed car chases, people are becoming more and more susceptible to its influences (Felson 1996) making the vicious cycle of watching, getting involved in, and broadcasting them unending.

Point of Presence Advertising Essay Example | Topics and Well Written Essays - 1000 words

Point of Presence Advertising - Essay Example The author planned to purchase a movie named Lord of the Rings - Fellowship of the Ring on recommendation of a friend and came across a pack of all the three movies of Lord of the Ring series at a price that was 20% less than the overall cost had the movies been purchased separately. The author realized that he anyway had to purchase the other two movies to complete the story and was delighted to get all the three of them at 20% discount. In the second purchase instance, the author was delighted to realize the value of the package as he owns both a Sony digital camera and Handy Cam. The total price was cheaper by 15%. Such product promotion advertisements resulted in positive impact on the author because the overall value of the buying decisions improved although the author didn't had planned for part of the purchase. The effectiveness of these two "Point-of-Sale" advertisements resulted in win-win deal for both the store and the author - the store increased the net sale value and th e author got more useful products at lesser cost. The author was not at all annoyed but was happy with the sales girl for introducing these offers. Massy and Frank (1966. pp383) presented the findings of an exploratory study on behavior of retailer advertising thus establishing some interesting empirical generalizations. They could prove that the brands sell differently in different stores and the support to a brand depends upon the brand's market share in a particular store type. The author discovered a linkage of this theory with the research by Kumar and Leone (1988. pp178-179) which stated that many customer packaged good manufacturers have resorted to funding short term sales promotion at the store level which primarily has two distinct advantages - the effectiveness of promotions can result in on the spot sales activity and the store management takes pride into participating in on the spot campaigns given increased margins & commissions. Both the manufacturer and the store management gain in this process - the former achieves brand promotion & quick sales and the latter achieves improved profitability of the store. Howeve r the store management normally achieves short term benefits but the manufacturers achieve long term benefits by achieving strong customer franchise through brand substitution. From the author's perspective one good observation about this model is that the on the spot promotional activities sometimes are effective enough to modify the purchase plan by the customers that they had made before visiting the store. Bucklin and Lattin (1991. pp24) observed that "point-of-purchase promotion is particularly attractive given the large pro-portion of grocery purchase decisions made after entering the store". They further observed that "two-thirds of supermarket purchases are the result of an in-store decision". Culturally speaking, such campaigns has promoted a culture of "fun buying" even avail such promotions to just find out what's hot on the day and carry out on the spot purchase decisions. Many a times, customers just get impressed by the sales skills of the sales person and do not bothe r what brand they are buying. Hence the

South Koreas Economic Indicators and Recent Growth Rate Assignment

South Koreas Economic Indicators and Recent Growth Rate - Assignment Example The growth theory places emphasis on increasing government expenditure, net exports (exports-imports) and investments which are obtained from savings. South Korea’s GDP growth levels can be traced to its increase in export levels, investment levels, and government expenditure. Therefore, the growth theory matches quite well with the economic development and growth in South Korea and its contributing factors-investment, exports and government expenditure. Rapid growth levels coincide with extensive government interventions on the economy. Economic and political policies were geared towards a free capitalistic economy with little government interference except in adjusting externalities resulting from the market failure. The political structure was also adjusted in order to support a capitalistic economy. Investment in human capital refers to investing in nutrition and health, schools and higher education, investment in children, migration, fertility rates, infant mortality rates and maternal healthcare. For example, by analyzing the infant mortality rates or literacy levels of the population, there is a clear positive correlation between an increase in the levels of literacy and infant mortality and an increase in GDP. Investing in children is particularly crucial for long-term economic growth and development of any country. Investment in human capital plays an integral role in any country’s economic growth and development. From the data, it is easy to identify the correlation between GDP and initial human and physical capital. Therefore, countries with greater human capital have greater economic growth Ceteris Paribas. The high human and physical capital levels determine the productivity levels of South Korea.
