Management E-Commerce Research Paper Example | Topics and Well Written Essays - 1000 words
Management E-Commerce - Research Paper Example Companies appoint managers to make sure that the company is effective, meaning the degree to which the company is able to reach its defined goals. Efficiency on the other hand means amount of resources used to achieve an organizational goal. Management must ensure that they operate in an effective and efficient manner in order to compete in todayââ¬â¢s competitive market. Management need to plan, or in other words defining goals for the future of the organization and deciding the tasks and resources that would be required in order to achieve those goals. Organizing means to allocate tasks and jobs and allocating resources amongst departments. Leading refers to the fact that they are able to motivate the employees to extract higher productivity. Lastly, controlling; it is the monitoring of employees ensuring that the organization is on track to attain the specified goals and making corrections if ever required. (Daft) There are a number of organizations in the world who succeed bas ed on their procedural management, which could be called the old school way, where boundaries are defined and the employ has to act according to the dogma of the task at hand. However, recently we have seen that various companies like Google have reached high level of success by using rather unorthodox, yet productive methods of management to avoid alienation of employees and to make the a part of the company rather than just a small cog in a big machine. Google has burst into the international market with its varied range of products and services ranging from the biggest search engine available to Google news, Google earth, maps, cellular phones and many, many more various products. Google uses an unorthodox and unconventional mode of management that is rather new to other organizations; some may call it bizarre, but at the end of the day one has to respect the fact that it earns more than $2billion cash per quarter and it is said that Google alone can finance the whole economy of America for 2 two whole days. Google has an informal slogan, ââ¬Å"donââ¬â¢t be evil.â⬠This basically expresses that at Google you are always welcomed to share ideas and their ways of doing business is open to all and there are no strings attached. They believe that these are the ways through which they can make sure that the employees are more comfortable and are able to perform to their potential in the field. As a matter of fact, Google employees are allowed to wear whatever clothes that pleases them. They have an all you can eat food counter that serves exquisite gourmet to motivate workers further. Google management believes that in order to avoid alienation, they must maintain good, informal relations with employees and also encourages employees to put forward their view and get involved in the decision making procedure since they believe that employees perform better when given importance and getting them involved in ideas enables innovation from various intellectua l minds, which at the end of the day is something Google always places very high importance to. Google management also has their very famous 20 percent rule. They say that for one whole working day an employee can work on whatever project that pleases them and as Google has ample amounts of finances, they are able to carry out their operation which thus leads to innovation. Rest of the days, they work on the project they have been assigned. This ensures effective, if

How can we adapt the design & structure of a british mosque in order Essay
How can we adapt the design & structure of a british mosque in order for it to comply with the architectural development of the modern world (britain) - Essay Example But Minaret and/or dome is/are claimed to be divine properties of mosques and any rejection of them is seen as an opposition to Islam. Edwards Said in his 'Orientalism' says clearly that such symbols are truly needed as, "we all need some foundation on which to stand." (3) In many of the parts of Britain it has been seen that a different kind of religious structures of mosques are formed. Thus, excluding minarets and domes. The public face of mosques need greater attention according to traditionalists. They question that how such buildings of ever changing context in Britain can be associated with Islamic world. It should also be considered that 40-50 years ago the immigrants were quite happy to pray in a make shift house in a terrace house. And as the worship place seemed too small they also didn't mind in buying and converting the schools, bigger houses and warehouses into buildings of worship. This clearly indicates that the only important thing in Islam is to offer prayers to Allah without any external support needed as minarets and domes. Another contemporary leading mosque builder, Al- Sumaria is one of the new generations of Muslims who has much radical approach and states that, "There are four features you must have, first of all you must have a dome you must have a minaret, you must have a Mehrab (the equivalent to an alter) you must have a babul Sulum what we call a frontal entrance. Those 4 features are of paramount importance, without it really any place can be a mosque." (4) This is the basic generational issue where most of the elders do not accept the modern architecture, confiding into commission of building, still not understanding what good architecture is. The younger generation finds the traditional style mosques quite old fashioned and want something more exciting while containing the basic essence that is true worship. According to Al-Sumaria the traditional British Mosques are not doing what people who want the building to respond should. Today the purpose built buildings are a bit more established as people want to raise some money from these to procure the buildings and moving from the adhock alteration of a building. But is it fundamental. The question is serious only if the essential essence of Mosques will be forgotten i.e. converting a building only to make it useful for praying, for Muslim worship. Aim, Objectives and Hypothesis The central aim of the paper is to present the ideal structure and architecture of Mosques in Britain and if any of the modern contemporary changes are affecting the basic element of faith of Islam. The idea of the mosque ever since is that it is place of worship serving as a sacred and clean space for prayer and also providing counselling, education and other services associated with the benefit of a community. They only need is to provide a space for all these services without any direct relation with minarets and domes. K. Alavi highlights that, historically the mosque is an institution with four major roles: a place of worship, a centre of education, a judicial court and a centre for political and administrative

Study On CPU And Memory Hierarchy
Study On CPU And Memory Hierarchy CPU must have compatibility with the memory in the computer system. Memory cannot increase the speed of the processor however it can help the processor increase its performance. If the CPU doesnt get the data it requires, it would sit idle wasting CPU clock cycles that would decrease the overall throughput and execution of the processes. If data needs to be accessed to and from hard disk which is slower as compared to the main memory, more and more cycles are wasted decreasing the efficiency of the system. Conclusion- For better performance of the system, faster program execution and proper CPU utilization the compatibility between CPU and memory is required. A computer employs RAM chips of 256*8 ROM chips of 1024*8. The computer society system needs 2K byte of RAM 4KBYTE of ROM, 4 interface units. Each with 4 registers. A memory mapped I/O configuration is used. The 2 highest order bits of the address bus are connected with address 00 or RAM and 01 for ROM 10 for interface. How many RAM ROM chips are needed? Draw a memory address map. 2 kb of RAM required i.e. 21024(bytes) =2048 bytes (Since 1 kb =1024 bytes) RAM = = 8 chips; and 4kb of ROM is required i.e. 4 x 1024 = 4096 bytes Therefore ROM = = 4 chips; and There are 4 interfaces each having 4 register, So total no. of registers is 44=16 registers; Memory address map Cache Coherence- Caches allow greater performance by storing frequently used data. In multiprocessing system, each processor is provided with its own cache and they all share the same memory or address space so it is possible for more than one processor to access a data item at a time. What if one processor updates the data item without informing the other processors, inconsistencies may result and cause incorrect executions and the problem of inconsistencies is known as Cache Coherence in computing. The coherence of caches is obtained if the following conditions are met. However these read and write operations are said to be one after another and this is not possible due to memory access latency and a write by first processor may not be seen by a read from second processor if the read is made within a very small time after the write has been made. Case 1 Case 2 Processor P1 reads memory location X and then writes back to same location X while no other processor is not accessing the memory location X. Processor P1 reads and then processor P2 writes to and from same location X and currently the location would return value written by processor P2 only. Processor P1 and P2 writes to same memory location X in a sequence and currently the value returned would be decided as per the sequence. Mechanisms- Bus Snooping- In Bus Snooping each cache is connected through the same bus and it is where every CPU knows who has a copy of its cached data. So each CPU watches continually for write activity concerned with data addresses which it has cached. This assumes that all communication can be seen by all. However it is far more complex to implement. Directory Based Approach- In a directory-based system, the data being shared is placed in a common directory that preserves the coherence connecting caches. The directory acts as a filter through which the processor must ask authorization to fill an entry from the primary memory to its cache. When an entry is distorted the directory either updates or invalidates the other caches with that entry. The MESI protocol is the best suited protocol to avoid cache coherence, where M stands for MODIFIED, E stands for EXCLUSIVE, S stands for SHARED and I stands for INVALID. Write Back Cache- Cache uses two approaches to write data back to main memory. Write Through Write Back It is the simplest one in which all write all operations are made to the main memory as well as to cache; ensuring main memory is always valid. Any other CPU- cache module can monitor traffic to main memory to update the data in its own cache, but always results in substantial memory traffic. It minimizes memory writes. In write back method modifications to data in the cache arent copied to the cache source until absolutely necessary. It is also known as copy back cache .In write back updates are made only in the cache. When an update occurs UPDATE bit are set associated with the slot and when the block is replaced it is checked whether the UPDATE bit is set or not. If it is set then data is written back to main memory. For Example- Intel processors since the 80486 uses back caching. Problem with this kind of implementation is that performance improvement comes with a slight threat that data may be vanished if the system crashes and more complex circuitry. Onboard Cache- Cache is a part of multi-level storage strategy which is used to increase the performance of CPU by providing a bridge in between the slower memory RAM and CPU. The cache that is the part of the CPU is known as off-board cache and the cache which is present on the motherboard is known as on-board cache. Generally L1 cache is referred as off-board and L2 is known as on-board. Sometimes L3 cache is also present on the motherboard along with L2. Now a days specific CPU vendors incorporates L2 as a part of CPU and L3 on motherboard. Implementation of Cache- In Cache, latency needs to be decreased and hit rate needs to be increased. Larger caches have better hit rates but longer latency. To address this problem, many computers use multiple levels of cache. The smaller and faster one is L1 cache built inside the CPU known as on-chip. If CPU needs data it first checks in L1; if it hits the processor proceeds at high speed. If the smaller cache misses, the next larger cache (L2) is checked, and so on, before external memory is checked. As the latency difference between main memory and the fastest cache has become larger, some processors have begun to utilize as many as three levels of on-chip cache. For Example- Intels Xeon MP Product code-named Tulsa, AMD Phenom II (2008), Intel Core i7 (2008) uses unified L3 cache. However Cache can be implemented by using Direct Mapped, Associative Mapping or Set-Associative Mapping. Virtual Memory- For the execution of programs memory required is more than what is actually present. So, the technique used to overcome this size limitation is Virtual Memory which is illusion of memory not physically present. The purpose is to allow multiple programs share same memory allowing splitting up of program into smaller pieces that can be loaded into different parts of memory whenever space can be found. Implementation of Virtual Memory- It is implemented using two techniques- one is Demand Paging and other one is Demand Segmentation. CPU generates address which is not physically present. These are the program addresses referred to as logical addresses, they dont have any existence outside the program, the actual memory addresses are known as physical addresses. These virtual addresses are mapped or interchanged to its corresponding physical address through a process known as mapping. A page table or look up table is maintained for this purpose. In Demand paging, valid-invalid bit scheme is used in which a valid-invalid bit is associated with each page. 1 for the page in memory and 0 for not present in memory. During address translation if bit in entry is 0 the page fault occurs. In virtual memory process are divided into chunks of equal size known as pages and chunks of memory in which pages are loaded are known as frames. In Demand Segmentation each row of the lookup table contains a starting address for a logical block of memory, together with the size of the block and a corresponding starting address in physical memory. Paging and Segmentation operates both the same. Problem of Fragmentation- Fixed Memory Partitioning- Operating system occupies fixed portion of main memory and partitions are created for multiple processes but not of same size, so there will be wastage of memory. In most cases the process will not acquire memory provided to it. Variable Memory Partitioning- In variables-size partitions, the memory allocated is as much it is required by process. However when processes are swapped in, small holes are created leading to problem of fragmentation. Compaction is done to solve problem, but it waste CPU time. In Virtual Memory demand paging method is implemented, in which memory is partitioned into equal chunks that are relatively small, and each process is divided into small fixed size chunks of some size. The lists of the frames that are free are maintained by the operating system. As the size of the pages and frames are same so suffer less fragmentation problem. The Memory Hierarchy The design constraints on a computers memory can be summed up by three questions: how much memory is available, how fast it is and how much it will cost? Following are the relationships between these tradeoffs- Smaller access time, greater cost per bit. Greater capacity, smaller cost per bit. Greater capacity, greater access time. Access Time Increase Transfer Rate DecreasesCPU Registers Cache Cost per/bit Decreases Capacity IncreasesRAM Magnetic Disk Figure -Memory Hierarchy Memory hierarchy helps in increasing the performance of processor, without hierarchy, faster process wont help and all time waiting on memory, It provides a large pool of memory that costs as much as the cheap storage near the bottom of the hierarchy, but that serves data to programs at the rate of the fast storage near the top of the hierarchy. It provides a faster access of data stored in the memory. If it is understand how the system moves data up and down the memory hierarchy, then application programs can be written so that data items are stored higher in the hierarchy, where the CPU can access them more quickly. Addressing modes affecting performance of system- It simplifies the memory references, produces variable length instruction format and instruction manipulates operands in memory directly. It adds convenience and flexibility to have modes of addressing, and it allows a large range of addressable memory while using a reasonable number of bits. Addressing modes make it easier to write certain type of programs such as loops that uses an index to address different entries in a table or array. For Example- Indexed Addressing. Now a days computer allows programmer accessible registers that manipulate data directly between registers.

The Life and Theories of Charles Darwin Essay -- Biography Biographies
The Life and Theories of Charles Darwin Charles Robert Darwin was the fifth child of Robert Waring Darwin and Susannah Wedgewood. He was born on February 12, 1809 in Shrewsbury, England where his father practiced medicine. He attended Shrewsbury Grammar School which was a well-kn own secondary school which concentrated on teaching classic languages. Even as a boy Darwin loved science and his enthusiasm for chemical studies earned him the name "Gas" from his friends. The headmaster at Shrewsbury, Dr. Samuel Butler noted, "Here's a boy, plays around with his gases and the rest of his rubbish and works at nothing useful." He was also an avid collector. Anything he could get his hands on- shells, eggs, minerals and coins interested him. Darwin was expected to follow his father and become a doctor and in 1825, at the age of sixteen, his father removed him from Shrewsbury and entered him in the University of Edenburgh to study medicine. He found all of his classes except chemistry dull. After two years at Edenburg, he quit school and went to live with his Uncle Josiah Wedgewood. After he abandoned medicine, his father urged him to attend Cambridge University to study to be a clergyman. At Cambridge he met John Steven Henslow who helped him regain his interest in nature. It was Henslow who was influential in getting Darwin the position of naturalist on the boat The Beagle. In April of 1831, he graduated from the University. In the fall following his graduation, the government decided to send the H.M.S. Beagle, under the command of Captain Fitzroy, to complete an unfinished survey of Patagonia and Tierra Del Fuego to help map out the shores of Chile and Peru. Th e voyage w... ...rstand or explain whatever I observed and group a ll facts under some general laws..." On April 19, 1882 Darwin died of a heart attack. The family wanted Darwin to be buried in his home, the village of Downe. However, Parliament requested that he be buried in Westminster Abbey, a cemetery for Britain's kings and queens and intellectual giants. This was an indication of how far Darwin had come towards universal acceptance and respectability. Darwin's coffin lies next to Issac Newton which is only fitting because Darwin has been called "The Newton of Biology." Darwin was modest of his monumental achievements to the very end and said of himself shortly before his death,"With such moderate abilities as I possess, it is truly surprising that I should have influenced to a considerable extent the belief of scientific men on some important points."

Mankiw Chapter 1 Solution
The answers to the Quick Quizzes can also be found near the end of the textbook. 1. The four principles of economic decision making are: (1) people face trade-offs; (2) the cost of something is what you give up to get it; (3) rational people think at the margin; and (4) people respond to incentives. People face trade-offs because to get one thing that they like, they usually have to give up another thing that they like. The cost of something is what you give up to get it, not just in terms of monetary costs but all opportunity costs.Rational people think at the margin by taking an action if and only if the marginal benefit exceeds the marginal cost. People respond to incentives because they choose activities by comparing benefits to costs; therefore, a change in these benefits or costs may cause their behavior to change. The three principles concerning peopleââ¬â¢s economic interactions are: (1) trade can make everyone better off; (2) markets are usually a good way to organize eco nomic activity; and (3) governments can sometimes improve market outcomes.Trade can make everyone better off because it allows countries to specialize in what they do best and to enjoy a wider variety of goods and services. Markets are usually a good way to organize economic activity because the invisible hand leads markets to desirable outcomes. Governments can sometimes improve market outcomes because markets may fail to allocate resources efficiently due to an externality or market power.The three principles that describe how the economy as a whole works are: (1) a countryââ¬â¢s standard of living depends on its ability to produce goods and services; (2) prices rise when the government prints too much money; and (3) society faces a shortrun trade-off between inflation and unemployment. A countryââ¬â¢s standard of living depends largely on the productivity of its workers, which in turn depends on the education of its workers and the access its workers have to the necessary t ools and technology. Prices rise when the government prints too much money because more money in circulation reduces the value of money, causing inflation.Society faces a short-run trade-off between inflation and unemployment that is only temporary. Policymakers have some short-term ability to exploit this relationship using various policy instruments. 2. 3. Questions for Review 1. Examples of trade-offs include time trade-offs (such as studying one subject over another or studying at all compared to engaging in social activities) and spending tradeoffs (such as whether to use your last 15 dollars to purchase a pizza or to buy a study guide for that tough economics course).The opportunity cost of seeing a movie includes the monetary cost of admission plus the time cost of going to the theater and attending the show. The time cost depends on what else you might do with that time; if it is staying home and watching TV, the time cost may be small, but if it is working an extra three ho urs at your job, the time cost is the money you could have earned. The marginal benefit of a glass of water depends on your circumstances. If you have just 2. 3. Chapter 1/Ten Principles of Economics 2 un a marathon or you have been walking in the desert sun for three hours, the marginal benefit is very high. But if you have been drinking a lot of liquids recently, the marginal benefit is quite low. The point is that even the necessities of life, like water, do not always have large marginal benefits. 4. Policymakers need to think about incentives so they can understand how people will respond to the policies they put in place. The text's example of seat belt laws shows that policy actions can have unintended consequences.If incentives matter a lot, they may lead to a very different type of policy; for example, some economists have suggested putting knives in steering columns so that people will drive much more carefully! While this suggestion is silly, it highlights the importance of incentives. Trade among countries is not a game with some losers and some winners because trade can make everyone better off. By allowing specialization, trade between people and trade between countries can improve everyone's welfare.The ââ¬Å"invisible handâ⬠of the marketplace represents the idea that even though individuals and firms are all acting in their own self-interest, prices and the marketplace guide them to do what is good for society as a whole. The two main causes of market failure are externalities and market power. An externality is the impact of one personââ¬â¢s actions on the well-being of a bystander, such as from pollution or the creation of knowledge. Market power refers to the ability of a single person (or small group of people) to unduly influence market prices, such as in a town with only one well or only one cable television company.In addition, a market economy also leads to an unequal distribution of income. Productivity is important because a country's standard of living depends on its ability to produce goods and services. The greater a country's productivity (the amount of goods and services produced from each hour of a worker's time), the greater its standard of living will be. Inflation is an increase in the overall level of prices in the economy. Inflation is caused by increases in the quantity of a nation's money.Inflation and unemployment are negatively related in the short run. Thus, reducing inflation entails costs to society in the form of higher unemployment in the short run. 5. 6. 7. 8. 9. 10. Problems and Applications 1. a. A family deciding whether to buy a new car faces a trade-off between the cost of the car and other things they might want to buy. For example, buying the car might mean they must give up going on vacation for the next two years. So the real cost of the car is the family's opportunity cost in terms of what they must give up.For a member of Congress deciding whether to increase spending on national parks, the trade-off is between parks and other spending items or tax cuts. If more money goes into the park system, that may mean less spending on national defense or on the police force. Or, instead of spending more money on the park system, taxes could be reduced. b. Chapter 1/Ten Principles of Economics c. 3 When a company president decides whether to open a new factory, the decision is based on whether the new factory will increase the firm's profits compared to other alternatives.For example, the company could upgrade existing equipment or expand existing factories. The bottom line is: Which method of expanding production will increase profit the most? In deciding how much to prepare for class, a professor faces a trade-off between the value of improving the quality of the lecture compared to other things she could do with her time, such as working on additional research. d. 2. When the benefits of something are psychological, such as going on a vacation, it is not e asy to compare benefits to costs to determine if it is worth doing.But there are two ways to think about the benefits. One is to compare the vacation with what you would do in its place. If you did not go on vacation, would you buy something like a new set of golf clubs? Then you can decide if you would rather have the new clubs or the vacation. A second way is to think about how hard you had to work to earn the money to pay for the vacation. You can then decide if the psychological benefits of the vacation were worth the psychological cost of working.If you are thinking of going skiing instead of working at your part-time job, the cost of skiing includes its monetary and time costs, which includes the opportunity cost of the wages you are giving up by not working. If the choice is between skiing and going to the library to study, then the cost of skiing is its monetary and time costs including the cost of getting lower grades in your courses. If you spend $100 now instead of saving it for a year and earning 5 percent interest, you are giving up the opportunity to spend $105 a year from now.The fact that you have already sunk $5 million is not relevant to your decision anymore, because that money is gone. What matters now is the chance to earn profits at the margin. If you spend another $1 million and can generate sales of $3 million, you'll earn $2 million in marginal profit, so you should do so. You are right to think that the project has lost a total of $3 million ($6 million in costs and only $3 million in revenue) and you should not have started it. That is true, but if you do not spend the additional $1 million, you will not have any sales and your losses will be $5 million.So what matters is not the total profit, but the profit you can earn at the margin. In fact, you wouldd pay up to $3 million to complete development; any more than that, and you will not be increasing profit at the margin. Harry suggests looking at whether productivity would rise or f all. Productivity is certainly important, since the more productive workers are, the lower the cost per gallon of potion. Ron wants to look at average cost. But both Harry and Ron are missing the other side of the equation? revenue. A firm wants to maximize its profits, so it needs to examine both costs and revenues.Thus, Hermione is right? it is best to examine whether the extra revenue would exceed the extra costs. Hermione is the only one who is thinking at the margin. a. The provision of Social Security benefits lowers an individualââ¬â¢s incentive to save for retirement. The benefits provide some level of income to the individual when he or she retires. This means that the individual is not entirely dependent on savings to support consumption through the years in retirement. Since a person gets fewer after-tax Social Security benefits the greater his or her 3. 4. 5. 6. 7. b.Chapter 1/Ten Principles of Economics earnings are, there is an incentive not to work (or not work as much) after age 65. The more you work, the lower your after-tax Social Security benefits will be. Thus, the taxation of Social Security benefits discourages work effort after age 65. 8. a. b. When welfare recipients have their benefits cut off after two years, they have a greater incentive to find jobs than if their benefits were to last forever. 4 The loss of benefits means that someone who cannot find a job will get no income at all, so the distribution of income will become less equal.But the economy will be more efficient, because welfare recipients have a greater incentive to find jobs. Thus, the change in the law is one that increases efficiency but reduces equity. 9. By specializing in each task, you and your roommate can finish the chores more quickly. If you divided each task equally, it would take you more time to cook than it would take your roommate, and it would take him more time to clean than it would take you. By specializing, you reduce the total time spent on chore s. Similarly, countries can specialize and trade, making both better off.For example, suppose it takes Spanish workers less time to make clothes than French workers, and French workers can make wine more efficiently than Spanish workers. Then Spain and France can both benefit if Spanish workers produce all the clothes and French workers produce all the wine, and they exchange wine for clothes. 10. a. To produce the right number of CDs by the right artists and deliver them to the right people requires an enormous amount of information. You need to know about production techniques and costs in the CD industry. You need to know each person's musical tastes and which artists they want to hear.If you make the wrong decisions, you will be producing too many CDs by artists that people do not want to hear, and not enough by others. Your decisions about CDs will carry over to other decisions. You have to make the right number of CD players for people to use. If you make too many CDs and not enough cassette tapes, people with cassette players will be stuck with CDs they cannot play. The probability of making mistakes is very high. You will also be faced with tough choices about the music industry compared to other parts of the economy.If you produce more sports equipment, you will have fewer resources for making CDs. So all decisions about the economy influence your decisions about CD production. b. 11. Countries that have corrupt police and court systems do not enforce individual property rights, including the rights over the goods and services produced by households and firms. Firms will not choose to produce products and individuals will choose not to work if there is no guarantee that they will receive payment for their efforts. Therefore, these countries end up with a lower standard of living. . b. c. d. e. Efficiency: The market failure comes from the market power of the cable TV firm. Equity Efficiency: An externality arises because secondhand smoke harms nonsmok ers. Efficiency: The market failure occurs because of Standard Oil's market power. Equity 12. Chapter 1/Ten Principles of Economics f. 13. a. 5 Efficiency: There is an externality because of accidents caused by drunk drivers. If everyone were guaranteed the best health care possible, much more of our nation's output would be devoted to medical care than is now the case.Would that be efficient? If you believe that doctors have market power and restrict health care to keep their incomes high, you might think efficiency would increase by providing more health care. But more likely, if the government mandated increased spending on health care, the economy would be less efficient because it would give people more health care than they would choose to pay for. From the point of view of equity, if poor people are less likely to have adequate health care, providing more health care would represent an improvement.Each person would have a more even slice of the economic pie, though the pie wo uld consist of more health care and less of other goods. When workers are laid off, equity considerations argue for the unemployment benefits system to provide them with some income until they can find new jobs. After all, no one plans to be laid off, so unemployment benefits are a form of insurance. But there is an efficiency problem? why work if you can get income for doing nothing? The economy is not operating efficiently if people remain unemployed for a long time, and unemployment benefits encourage unemployment.Thus, there is a trade-off between equity and efficiency. The more generous unemployment benefits are, the less income is lost by an unemployed person, but the more that person is encouraged to remain unemployed. So greater equity reduces efficiency. b. 14. Because average income in the United States has roughly doubled every 35 years, we are likely to have a better standard of living than our parents, and a much better standard of living than our grandparents. This is mainly the result of increased productivity, so that an hour of work produces more goods and services than it used to.Thus, incomes have continuously risen over time, as has the standard of living. If Americans save more and it leads to more spending on factories, there will be an increase in production and productivity, because the same number of workers will have more equipment to work with. The benefits from higher productivity will go to both the workers, who will get paid more because they are producing more, and the factory owners, who will get a return on their investments. There is no such thing as a free lunch, however, because when people save more, they are giving up spending. They get higher incomes at the cost of buying fewer goods.To make an intelligent decision about whether to reduce inflation, a policymaker would need to know what causes inflation and unemployment, as well as what determines the trade-off between them. This means that the policymaker needs to unders tand how households and firms will adjust to a decrease in the money supply. How much will spending decline? How much will firms lower output? Any attempt to reduce inflation will likely lead to higher unemployment in the short run. A policymaker thus faces a trade-off between the benefits of lower inflation compared to the cost of higher unemployment. Answers will vary. 15. 16. 17.

Amy Tan, Two Kinds Essay
This storyââ¬â¢s main events take place in Chinatown throughout the 1950s and perhaps early 1960s. The main character of the story, who is also the protagonist, is the author herself: Amy Tan. The antagonist happens to be her own mother, who is always pushing Amy to discover some hidden talent and be someone she is not. There are a few other minor characters in the story. There is Lindo Jong (who she calls Auntie Lindo), who is a close friend of Amyââ¬â¢s mother. Waverly Jong is Auntie Lindoââ¬â¢s daughter, who is close to Amyââ¬â¢s age. Amyââ¬â¢s piano instructor, who she calls ââ¬Å"Old Chongâ⬠, plays a small role in the story. Amyââ¬â¢s dad is included in the text, but does not play much of a role. In ââ¬Å"Two Kindsâ⬠, the exposition is clear in the first couple of pages. The story begins by explaining that Amyââ¬â¢s family moved to America when she was a baby, in 1949. Her mother is clear in her goals: she wants Amy to be a child prodigy (a person with exceptional talent) and famous. Although in the beginning Amy seems accepting of her motherââ¬â¢s goal, there are some undertones which are clear to the reader that her mother may go too far. Symbolism in literature ââ¬Å"might include visual or sound elements as well as languageâ⬠. Amyââ¬â¢s piano was the main symbol of this story. In the end of the story, the fact that she had it tuned and actually sat down to play shows us that she really cared about her mother-and the piano-after all. The songs that she plays at the end are also a symbol of the story, itself. She mentions playing two songs. The first is titled ââ¬Å"Pleading Childâ⬠, and the second one: ââ¬Å"Perfectly Contentedâ⬠. These are songs that she had played when she was a child. She notices for the first time, after all of these years, that these two songs are actually two halves to the same song. The song represents Amyââ¬â¢s life. This is how the story ends. We get a pretty good idea of what Amyââ¬â¢s story is about and the theme behind it. She regrets not trying her best, and the way she has taken her mother for granted in her life. A strong message like this makes us reflect on our own lives and relationships with the ones we love. Amy constructs the story in a way that makes the plot flow, and we are interested in what will happen to her next. Some of us may even feel like she is too hard on the protagonist-her mother. The ending resolves these feelings, because we discover she feels this, too.

The Importance of semantics and syntax in sentence recall essays
The Importance of semantics and syntax in sentence recall essays This study was set to examine the importance of semantics and syntax in the brains ability to process and correctly recall content words (nouns, verbs, adjectives, adverbs) in sentences (Miller, Isard 1963). The sample involved 140 first year psychology students attending a compulsory laboratory at the Australian National University. The experiment was conducted similarly to that of the Miller and Isard study (1963), in which subjects were presented with 60 different sentences. 20 of which were normal grammatical sentences (normal); 20 were semantically anomalous sentences that were syntactically sound (sem-syn+), and 20 were syntactically invalid sentences that were also semantically incoherent (syn-sem-). In attempts to support the results concluded from the Miller and Isard (1963) study a memory task was used that required subjects to accurately recall the constitute words in a sentence a short period after they were initially exposed. This task tested participants memory func tions and recall abilities whilst supporting the argument that claimed when sentences are both semantically and syntactically sound, the content words that make up the sentence will be recalled after a short duration of time more accurately than when the words are strung together in an ungrammatical fashion. The importance of semantics and syntax in sentence processing and retrieval When it comes to understanding the human ability of reconising integral words in sentences and then recalling them back after a short duration of time, one must acknowledge the important roles that both syntax and semantics play in this process. Many studies have been conducted in attempts to gain more information on the semantic processes, syntactic processes, and their coordination in sentence comprehension (Hahne & Jescheniak, 2001). Because the mechanisms underlying recall of meaningful sequences of words are not well understood, it has yet to be discovered...
