Pronunciation of Words With Weak and Strong Forms

Pronunciation of Words With Weak and Strong Forms English is a stress-time language which means that some words are stressed and others are not when speaking. Generally, content words such as nouns and principal verbs are stressed, while structure words such as articles, helping verbs, etc. are not.   The Structure of Words A number of structure words have both weak and strong pronunciation. As a rule, the structure will take the weak pronunciation which means that the vowel becomes muted. For example, take a look at these sentences: I can play piano.Tom is from New England. Here are these two sentences with accented words in italics. Mary can play piano.Tom is from Chicago. Can, and from and is are unaccented and the vowel is very weak. This weak vowel sound is often referred to as a schwa. In the International Phonetic Alphabet (IPA) the schwa is represented as an upside-down e. It is, however, also possible to use these words with a strong form. Take a look at the same structure words, but used with strong pronunciation: You CANT  play tennis. - Yes, I CAN.Where is Tom FROM? In these two sentences, the placement at the end of the sentence calls for the strong pronunciation of the word. In other cases, the usually unaccented word becomes accented as a means of stressing that something is contrary to what is understood by others. Look at these two sentences in a dialogue. You arent interested in coming next week, are you?Yes, I AM interested in coming! Try the following exercise to practice both the weak and strong form.  Write two sentences: One sentence using the weak form, and one using the strong form. Try practicing these sentences taking care to quickly glide over the vowel in the weak form, or pronouncing the vowel or diphthong sound firmly in the strong form. Here are a few examples: Ive heard you have a company in the city. No, I work FOR a company in the city.What are you looking for? She is our sister.OUR sister is so talented! Practice Activity Decide how the word indicated would change the meaning in the following sentences when using the strong form. Practice saying each sentence aloud alternating between weak and strong forms. Do you notice how the meaning changes through stress? I am an English teacher in Portland, Oregon. - strong amI am an English teacher from Portland, Oregon. - strong fromHe said that she should see a doctor. - strong shouldThey were able to find a job despite the difficult market. - strong wereDo you know where he comes from? - strong doIll give the assignment to them. - strong themShes one of our most valued students. - strong ourId like Tom and Andy to come to the party. - strong and Answers I AM an English teacher ... Its true even though you dont believe it..... teacher FROM Portland, Oregon. Thats my home city, but not necessarily where I live and teach now.  ... that she SHOULD see a doctor. Its my advice, not an obligation.They WERE able to find a job ... It was possible for them though you think not.DO you know where ... Do you know the answer to this question or not?... the assignment to THEM. Not you, the others.Shes one of OUR most valued students. She is one of us, not of you or them.... Tom AND Andy ... Not only Tom, dont forget Andy. Here are some of the most common words that have weak/strong pronunciations. Generally speaking, use the week form (schwa) pronunciation of these words unless they are stressed by coming at the end of a sentence or due to unnatural stress made to facilitate understanding.   Common Weak and Strong Words a / am / an / and / are / as / atbe / been / butcan / coulddo / doesfor / fromhad / has / have / he / her / him / hisismustnotof / ourshall / she / should / somethan / that / the / them / there / touswas / we / were / who / would / willyou / your

Macroeconomics and Microeconomics difference Essay

Macroeconomics and Microeconomics difference - Essay Example Microeconomics deals with individual demand and supply of individual goods and services in the market. The law of demand states that as price increases, the quantity of goods demanded decreases other things held constant hence quantity demanded and price are inversely related. The law of supply on the other hand, states that as price increases the quantity of goods supplied increases other things held constant hence a positive relationship between quantities supplied and price. The magnitude of change in quantity demanded depends on price elasticity of demand and supply (Mankiw & Taylor, 2006). However, there are many factors besides price that affects the quantity of goods demanded and supplied leading to a change in demand or change in supply. A change in price causes movements along the demand and supply curve other factors held constant. Wessels (2006) argues that there are bound to be changes which affect demand or supply such us level of income and weather changes. The demand for a good or service is affected by the price of the good, income of household and the firm, wealth, tastes and preferences, price of other products, number of households demanding a good or service (Anderton, 2000). If the income increases, households have more purchasing power hence demand more goods and services thereby shifting the demand curve to the right and if income decreases, households reduce the demand for goods thus shifting the curve downwards. Same case applies to increase or decrease in the wealth of firms and households. However, it depends on the type of good or service. For an inferior good, an increase in income or wealth leads to decrease in quantity demanded of the good but for normal goods, an increase in income or wealth leads to more demand for the good (Beggs, 2011). Mankiw (2011) notes that a change in demand as a result of change in taste and preference or price of related products depends on the type of goods affected. For example, if a consu mer changes his/her preference from Pepsi to coke which are substitute goods, the demand for coke increases while demand for Pepsi decreases. For substitute goods, an increase in price of one good leads to an increase in quantity demanded of the other good. For example, if price of coke increases relative to the price of Pepsi, consumers shift demand from coke to Pepsi which serves the same purpose. For complimentary goods, an increase in price of one good leads to decrease in quantity demanded of the other good. Macroeconomics Macroeconomics deals with aggregate demand and aggregate supply in the economy. Aggregate demand comprises of; consumption, investment, government expenditure, exports and imports or the real national output (GDP). As Kyer and Maggs (1994) puts it, macroeconomics is not concerned with price elasticity, marginal costs and revenues as well as individual choices but rather government policies and the behaviour of the economy as a whole. The aggregate demand in t he economy is not affected by price but rather other factors such as; expectations of households, income, wealth, interest rates,

Online Store Vs. Physical Store Assignment Example | Topics and Well Written Essays - 1000 words

Online Store Vs. Physical Store - Assignment Example All products further fall into categories for different markets. For instance, music accessories are sorted by price range in order to direct buyers to products that are willing to spend certain amounts. With the online store, one has the opportunity of shopping through a personal account. Personal accounts allow one the comfort of shopping without worrying about carrying along a credit card or cash. This is made possible by the available options of saving one’s payment information. In addition to this, accounts offer the opportunity of receiving news about new offers and discounts from the company through emails. In a physical store, one only gets to learn about discounts through publicly placed advertisements that are temporary and dependent on one’s location. Online stores save an immense amount of time for shoppers. People do not need to queue in order to check out. Queues can become tediously long especially during peak times. Moreover, the time it takes for differ ent customers to finish shopping is unrelated to the amount of products bought. The process of checking out at the online store is simplified to a few clicks within the site’s pages. In addition to this, burden of travelling in order to make a purchase is eliminated. The Express.com online store, for example, ships products directly to the customer free on certain purchases. What does the ‘brick and mortar’ store offer that the virtual store cannot? When customers shop at a physical Wal-Mart store, they have the opportunity to select products that they need in their actual forms. Certain aspects about the product may instantaneously affect the choice to make a purchase. One may realize that the size or the appearance of a product is not precisely, what you would want if you were in direct contact with it. At the store’s website, one only gets the chance to select the product based on visual appearances displayed online. There is a possibility of purchasing something only to realize it does not precisely match your preferences. For instance, one cannot try to fit a new piece of attire at Express’s online store, but this is possible at the physical store. This, hence, means that there is a risk of purchasing a cloth that does not fit your size. Furthermore, one may not be able to seek immediate assistance from store attendants when shopping online. Questions about a product have to be sought independently or at a time cost if one chooses to make phone calls to consult the customer support team. This slows down the buying process. Shopping at the physical store also allows one to access products instantly as opposed to the online store, where shipment has to be made over a certain period. One has the chance to interact with other buyers at the physical store, as opposed to an online situation where there will never be a chance of seeing other shoppers. Such interaction with fellow shoppers can help in gaining information about ce rtain products, for example, when trying to choose an appropriate book. Again, some products are not deliverable to certain locations if purchased online, for example, groceries. Thus, it requires one to travel physically to the store. Finally, at the physical store, one has the additional option of using cash to pay for shopping bills. If shopping is online, the only options available involve electronic money transfers. What

Linking and Illegal Trespassing Essay Example for Free

Linking and Illegal Trespassing Essay Bidder’s Edge was different than EBay normal customers for a few reasons. Bidder’s Edge searched for bids on EBay to compare with bids from other bidding sites to find the best bids for customers. Bidders Edge could have potentially slowed the access to EBay’s actual customers on EBay’s site directly (The Recorder, 2000). I feel EBay gained concern because this process could have lost them potential or current customers. For example, if EBay was being compared to other bidding websites with low bids, then it would be obvious that EBay would not be chosen by bidders. Bidders Edge for me seems a lot like Amazon. Amazon compares several stores prices to find their customers the lowest price. The difference with Amazon is that they only search stores that have granted them the permission to do so. Also unlike a bidding website, all prices are as is. Traditional trespass to personal property is entering a premise without permission, misusing or damaging the owner’s property and also preventing the owner of said property from using the property as the owner intended (Bick, 2000). The difference between traditional trespassing and to personal property differs from the California definition of trespassing to computer services is vastly. Where with the traditional trespass to personal property is easy to prove, the California definition of trespassing to computer services is not. California definition of trespassing to computer services states that the owner of web site has to prove that the use by trespasser has caused injury to web site or owner. Being that a majority of the internet is public access, it can be hard to not allow access to certain individuals and companies while considering themselves a public website. Also an internet site is much easier to access than a physical property and harder to prove.

Why Do Convenient Stores Have Locks On Their Doors If They Are Always :: essays research papers

Why Do Convenient Stores Have Locks On Their Doors If They Are Always Open? At 1:30 in the morning you are driving down Walton Road when you pass the 7-11. You decide to stop in and treat yourself to a nice big slurpee. As you pull in the parking lot you notice that the sign says, "We're open 24 hr's, 7 days a week, 365 days a year." However, when you reach the door you notice that they have locks on the doors and you think to yourself, why do convenient stores have locks on their doors if they're going to be open 24 hours a day, 7 days a week, and 365 days a year? If they're never going to close then they have no need for locks on the doors. This will only cause an inconvenience for employees and customers. The idea of adding locks onto the doors is only going to cost the store more money. Also, it would give the managers one extra key on their already big key chain that they really have no use for. Since they are open every second of the year, they never need to lock the doors between shifts. When one person's shift is over then the next person will come in and take over. It's not like most stores where at night when the store closes they lock the doors and go home. Then, in the morning whoever is going to be opening comes in and unlocks the store and gets it ready for the first customers of the day. This situation would never happen at a store that is open all the time because there always has to be someone working. On a rare occasion, the store might need to the lock the doors if someone outside is causing trouble. However, if they locked the doors and wouldn't let any customers in they would be lying saying that they're open 24 hours a day, 7 days a week, and 365 days a year. Doing this would cause the store to lose money because no one could then get into the store. By adding locks onto the doors would also make people think that sometimes they do close, like on holidays. On almost all national holidays like Thanksgiving and Christmas, stores will be closed to allow their valued employees time off to spend with family. If this was the case then some people might avoid shopping there on holidays in fear that when they get there they will be closed. Then they would have to drive all the way to another store

Problem Solving & Critical Thinking – Hdlt

Critical thinking and Problem Solving HDLT mini paper It is possible to store the mind with a million facts and still be entirely uneducated. Alec Bourne. According to American educational Psychologist – Robert M Gagne – â€Å"The central point of any education is to teach people to think, to use their rational powers, to become better problem solvers. â€Å" Looking at the current model of our own learning, in HDLT 2 class itself – as students of the second semester in the university; we have been exposed to theories of this subject before. It is now time for adapting, assimilating, applying the past knowledge in real life contexts.This adaptation is tested through fresh, innovative learning environments and higher expectations. Let us first determine critical thinking and problem solving and see how are these phenomenon interrelated with each other and the role both these skills play in our lives. Critical thinking (CT) is defined as â€Å" intellectually di sciplined process of actively and skillfully conceptualizing, applying, analyzing, synthesizing and /or evaluating information gathered from or generated by observations, experiences, reflections, reasoning or communication as a guide to belief and action. Scriven & Paul, 2007, P 1). Thus simply put, CT is metacognition or thinking about thinking. Problem-solving (PS) is a mental process that involves ascertaining, investigating and solving problems. The eventual objective of problem-solving is to overcome hindrances and find a solution that best resolves the issue. These problems could range from simply crossing the road and reaching safely on the other side without getting hurt by the oncoming vehicles or solving a Sudoku puzzle or figure out a estimated expenses of a trip or in case of a child, solving a multiplication sum given in the class.The term problem solving ( P S) in educational settings would involve solving well-structured text book problems which are poles apart from ill structured problems which are encountered in everyday life. Thus we can see that in order to effectively solve a problem, one may require to engage with it and critically think about it to find the best solution. Let us now look at certain important broad themes and specific problem solving processes used by children – Broad themes – 1. Task analysis – details of steps taken to actually solve problems.For example a child adds 2 multi digit numbers, the actual process – starting with adding the numbers in the right most column, writing ones digit as a part of the answer, carrying over the tens digit ( if it is so ) †¦ so on and so forth. Task analysis helps in identifying the exact places where child might be encountering difficulty in solving the problem, the nature of the difficulty. Thus it gives an insight into the manner in which the child solves problems; and thus provides scope for rectification. 2.Means – End analysis – Using this methodology, one solves a problem by considering the obstacles that stand between the initial problem state and the goal state. The path to reaching the goal can be achieved by accomplishing smaller sub goals. When all of the sub goals have been achieved – when all of the obstacles are out of the way – then the main goal of interest has been achieved. Thus, means-ends analysis can be seen as a search strategy in which the long-range goal is always kept in mind to guide problem solving. 3.Encoding – this literally means identifying critical information in order to build internal representations. Thus it is very important to train the child to filter out the relevant data from the all the available information. Many children fail because they are not thought how to encode critical information and utilize it. Important processes of Problem Solving- 1. Planning – this is future directed PS, most often used in difficult and new situations. But most often the novelty of the situation also ensures that children often forget to plan. 2.Route Planning – this is done in order to select a most efficient route in order to reach a destination. Children as early as one year of age start showing the development of this ability. Example – an adult figuring out his way in order to reach a new destination; after looking at various maps. The route is figured out post route planning. 3. Causal Inference – many a times problem solving is an attempt to understand the cause of a phenomenon. Humans are curious by nature. A two year old will constantly be in the endeavor to know â€Å"why things happen†Ã¢â‚¬ ¦ why do birds fly, whereas animals don’t? so on and so forth. 4.Analogical Reasoning – In problem solving this is predominantly concerned with systemic correspondences, where a solution to a known problem may be applied to solving a structurally similar problem. Analogical reasoning improves with maturati on and increase in content knowledge. According to Piaget’s stages of development analogical reasoning only starts developing in the pre operational stage ( ages 2 -7) and gets occasional limited success in concrete operational stage(7-11) and becomes fully developed by formal operational stage (age 11 through adulthood) Stage I (Preoperational) – egocentric responses using idiosyncratic relations.IA – children were unable to form lower-order relations IB – some children able to form lower-order relations, but unable to form analogies Stage II (concrete operational) – occasional, limited success IIA trial-and-error success on analogies, inability to resist false counter-suggestions IIB consistent success on analogies, but inconsistent ability to resist false counter-suggestions Stage III (formal operational) – Success on all aspects of the tasks. Criticism of Piaget – Goswami & Brown reasoned that children might fail Piaget's tasks be cause they lack knowledge of the relations entailed.On this view, children ought to be able to solve classical analogy problems provided the analogies are based on familiar relations. Practice in analogical reasoning improved young children’s spontaneous formation of analogies. 5. Scientific reasoning: Children question everything as a basic premise,they want to know the why , how of everything; but they are also hugely influenced by the beliefs that they see are carried around them. Whenever they actually do something on their own, they do develop an understanding and rationality regarding the same phenomenon.For example a child understands that sugar takes less time to dissolve in hot milk rather than cold milk. Thus, when they indulge in activities, experiment they develop scientific and logical reasoning. 6. Logical reasoning – It is when a child can apply logical rules in order to solve problems. Logical reasoning requires the child to link each alternative to the main problem by strong reasoning. They may also require using logical structure â€Å"If†¦ , Then †¦. † for example if a child has to climb up two floors, he could either use the lift or the stairs.If the escalator lift for some reason is not working, then either the child could wait till the lifet starts working or take the stairs. The choices have to be logically reasoned out. Both analogical and logical reasoning develop gradually over early and middle childhood whereas scientific reasoning does take more time to develop and take shape as it is much enhanced by experience. Along with certain important processes used in PS some of the others are – Symbolic representation as tools Rule based problem solving etc. Above we have also looked at Piagetian perspective on PS.Let us also look at the Vyogotsky’s perspective on the same. Lev Vygotsky gave some novel ideas regarding childrens learning and their problem solving abilities. 1. Zone of Proximal dev elopment (ZPD) – This is the zone where learning takes place. This zone represents the difference the between what the child can achieve on its own and what it can achieve with the help of others. In order, for learning to occur, the elder or peer must provide a challenge that is beyond the child’s own capabilities and yet be assisted. Thus assisted learning or peer learning is an important aspect of children developing the PS abilities.If children have done a task with an adult or under the guidance of an adult (ZPD) they tend to show improvement whilst performing as opposed to those who were attempting it for the first time ( Piaget’s discovery learning ). Vyogotsky also pointed towards the importance of private speech in children, whenever confronted with a novel problem. This speech could be their method of engaging with the problem. As children grow up and get better at symbolic interpretation, this private speech diminishes. Now let us look at how a constr uctivist classroom helps children in enhancing their PS abilities.Constructivist approaches to learning attempt to generate environments where learners are actively engaged in their surroundings and environments that help them to construct and develop their own understanding, reasoning and knowledge, rather than the teacher interpreting their world for them. The learners interaction with the environment and with the subject matter at hand results them in having their own view about the subject. Thus we can see that collaborative learning is the hallmark of a constructivist classroom. For example – group of students in a chemistry class are learning about properties of organic salts.Instead of directly stating the properties, the teacher will devise questions which will engage the students in challenging their previous knowledge, link it to the other phenomenon that they have already been studying and generate a new level of understanding regarding the topic. During the discus sions and promptings, when one student comes with the relevant concept, the teacher would cash on it and hint to the group to further explore this concept. Late, she would sum up ay concluding what the class has learnt, what helped and what did not help them in constructing new knowledge.Question – The biggest question for me is the teaching methodology. In most of the schools, that me and my colleagues have visited during our practicum, we inevitably noticed that instead of focusing on teaching the students how to think, rationalize, develop an understanding. The focus is on what they should think? Conclusion – By providing them everything like â€Å"ready to eat meals†, we seal them from developing their own understanding. In a class room setting children, still encounter structured problems, in real life settings children will be coming across many ill structured problems.The aim of education must be to prepare them for encountering the challenges that they w ould face everyday. They have to be trained to adequately use their problem solving abilities within the classroom as well as outside it. References – Taylor, L, (2005). Introducing cognitive development.
