High-level and Low-level Languages Essay Example | Topics and Well Written Essays - 1000 words

High-level and Low-level Languages - Essay Example The programming languages that are very similar to machine code (such as 0s and 1s) are acknowledged as low-level programming languages. Basically, in these languages the program instructions are written in binary form. In addition, low-level programming languages offer the programmer a high level control over hardware however they require a deep knowledge of the internal structure of the hardware to be used. These programming languages are not normally used by the programmers because it is very difficult to learn and understand them. High-level Languages The programming languages that are very similar to the human languages (e.g. like English language) are acknowledged as the high-level languages. The examples of high-level languages are FORTRAN, COBOL, BASIC, PASCAL, C++ etc. These languages are similar to the English language. In other words, it is relatively easy to understand the code written in high level programming languages. In these languages, program instructions are written using English words, for instance print, input, square etc. However, each high-level programming language has its own rules or grammar for writing program instructions. These rules are called syntax of the language. In addition, the program written in high-level language must be translated to machine code before they are executed on the computer. For this purpose, each high-level language has its own translator program, which converts the code of that source language into the computer understandable form. Advantages of High-Level Languages There are many advantages of high-level programming languages. Some of the most important advantages are outlined below: (ninja craze, 2012; Lee, 2000) Easy to Learn In view of the fact that the high level programming languages are similar to human languages thus they are very easy to learn as compared to low-level languages. The instructions written for the program are similar to English like statements. Easy to understand The program written in high-level language by one programmer can easily be understood by another programmer or person because the program instructions are similar to the English language statements. In this way, if a software application has been developed using a high level programming language can be modified by another programmer later on. Easy to write programs In a high-level languag

Radioactive Decay, Age Dating, Geologic Time Assignment

Radioactive Decay, Age Dating, Geologic Time - Assignment Example Now use the matches to represent a different radioactive element (with a different half-life). Write a "D" on one side of the box to indicate daughter isotopes. Place the matches in the box and shake well (up and down, not side to side as the matches will â€Å"line up† with side to side shaking). After shaking (one time step) remove all matches that point (using the head of the match as the pointing end) toward the end of the box that is indicated by the D. Record the number of remaining matches in the box and repeat until nearly all of the matches have been removed. Plot the results on both of the attached graphs. Use a dot for the coins and a plus sign for the matches. Connect the points on your graphs with a smooth line. Your graph should now resemble in shape the curve in Figure I-5. The more coins used, the better will be the resemblance. (The reason for this is that statistics do not apply well to small samples. An individual gambler can never predict how he or she migh t do on a given try at a slot machine but averaged over many thousands of gamblers, the casino owners are assured of a steady flow of profits.) In the same way, we can never predict just when an individual radioactive atom will decay, but when we are dealing with billions of atoms in rocks (which is always the case), we can be assured that the Law of Radioactive Decay is followed very closely. Use both the linear scale and logarithmic scale graph for the penny and the match data - plot both data sets (pennies and matches) on both graphs.

Health Level Seven International (HL7) letter Article

Health Level Seven International (HL7) letter - Article Example Various mandated changes looming on the horizon will not allow this practice to continue, for communication and cooperation between departments is essential. Therefore, the COO has made that my major function and the following are my recommendations for doing so. Discussion First, I will present background information as to why these changes are so necessary. President Bush signed Executive Order 13335 in 2004 mandating that Electronic Health Records (EHR) will be in place nationwide within ten years. Congress went a step farther, creating the 2009 Health Information Technology for Economic and Clinical Health Act (HITECH), and President Obama signed it into law. The act extended the deadline to 2015 but that is only two years away. After that, health facilities such as Toledo stand to lose millions of dollars in Federal Medicare and Medicaid monies if they are not in compliance. All would agree that would be a serious financial blow to our center. Fortunately, the Department of Heal th and Human Services (HHS) has created the HIT coordinator to help us navigate through the seemingly complex maze of regulations (HHS, 2013). There is a nonprofit organization called Health Level Seven (HL7), which has developed a series of standards generally accepted by both the health community and HHS and it is the intention of Toledo to comply with HL7 initiatives. Yet Corepoint points out that HL7 is a â€Å"non-standard standard† (2009) meaning that as no two snowflakes are alike, neither are any two healthcare facilities the same. The main point is that Toledo complies with the laws within the specific timeframe and conformity with HL7 standards will ensure this occurs. Much time and money has spent on developing the software currently utilized by Toledo’s various departments and I do not intend to dismantle any of their operations. Rather, it is my recommendation that we purchase new hardware that can accommodate all of the departments’ current softwar e systems. Interfaces take into account the lack of interchange between clinics and are commercially available, improving communication and interoperability. That is where HL7 comes into play. Without it, my staff and I would be forced to create said interface from scratch, a costly and time consuming process. Fortunately, HL7 V2 brought together software vendors and informatics specialists such as me to create said commercial products. Although V3 has largely superseded V2 in Europe, it will be some years before that happens in the United States, so Toledo will concentrate on V2 compliance. One of the major concerns of each clinical head is maintaining patient and provider privacy, still another requirement of Federal law. Therefore, it is tantamount that the interfaces provide the security necessary to ensure only the necessary information for patient care be provided across Toledo’s health informatics network. There is a very interesting case study concerning Lake Forest H ospital in Illinois (CDW 2013), which was faced with the same dilemma, In addition, when the clinics interfaced, the physicians and nurses had many passwords for the different clinical access (one for lab results, one for pharmaceutical, etc.). It is my intention that the interface chosen for Toledo

Reveal Topic As for today, I would like to elaborate and to highlight some important tips on how to be a good listener to everybody. IV. Preview Listening is an essential part of communication, and it is different from hearing. Being a good and patient listener helps you not only solve many problems at work or home, but also to see the world through the eyes of others, thereby opening your understanding and enhancing your capacity for empathy. [ Let me start with the steps and skills of being a good listener ] BODY i. Place yourself in the other persons shoes. a) look at the problems from the other persons perspective and actively try to see his or her point of view. b) It is not a good idea to consider yourself to be smarter than the speaker and assume that if you had been in his or her shoes, you would have seen your way through the problem much faster. c) Remember you have two ears and one mouth for a reason. ii. Create a conducive physical and mental space. a) Remove all distractions and give all of your attention. b) Turn off cell phones because it may be easiest to arrange to talk somewhere that distractions will not occur. c) Quiet your mind and open yourself to whatever the person might have to say. iii. Stop talking and try to be silent. a) It might sound obvious and trite, but one of the biggest obstacles to listening, for many people, is resisting the impulse thoughts. b) Likewise, many think that empathy means sharing with the listener similar experiences that the listener has had. Both can be helpful, but they are easily abused. c) Put aside your own needs, and wait for the other person to talk at their own pace. iv. Follow and encourage the speaker with body language. a) Nodding your head will indicate you hear what the speaker is saying, and will encourage them to continue. b) Adopting body postures, positions and movements that are similar to the speaker will allow the speaker to relax and open up more. c) Try to reassure the speaker that all is well. d) Whatever the conclusion of the conversation, let the speaker know that you have been happy to listen and to be a sounding board. e) Reassure the speaker of your intention to keep the discussion confidential.

Concluding Remarks In my observation, I think that Malaysians are lousy listeners. Let us start changing our attitude to being a good listener. Let’s start listening to our surrounding and giving respond to our society. All in all we can be a good listener in the world.

Analysis of Major Characters in Great Expectations Essay Example for Free

Analysis of Major Characters in Great Expectations Essay Pip is the main character of this story. The whole plot of the novel revolves around him and his metamorphosis into an adult from an immature adolescent.  1. Immature: pip was highly immature. This characteristic in him can be clearly seen in pg 59 where he says but when she was gone, I looked about me for a place to hide my face in and got behind one of the gates in the brewery lane and leaned my sleeve angst the wall there, and leaned my forehead on it and cried. As I cried, I kicked the wall and took a hard twist at my hair; so bitter were my feelings so sharp were the smart without a name that needed counteraction. Pip cries so much, suddenly begins to have such a low self esteem, why? Just because a girl came and commented that he had coarse hands, wore thick boots and called the knaves Jack. Instead of standing up for himself, pip simply cries. This goes to show how immature pip was.  Pips immaturity is also seen in his romantic idealism. Ever since his first meeting with beautiful Estella, he always thought of her in page 101 he says, often after dark, when I was pulling the bellows for Joe, and we were singing Old Clem, and the thought how we used to sing at Miss Haveshams would seem to show me Estellas face in the fire, with her pretty hair fluttering in the wind and her face scorning at me. Often at such a time I would look towards those panels of black night in the wall which the wooden windows then were, and would fancy that I saw her drawing her face away and would believe that she had come at last. In spite of Estella being so insulting he instantly falls for her, rather for her loo ks. This again shows the immaturity in pip. 2. Generous and sympathetic: pip was generous and sympathetic, a fact that can be seen in his numerous acts of kindness throughout the novel. In page ___ he sympathizes with Magwitch and helps him escape. A small boy going out of his way to help a wretched convict! This goes to show how sympathetic pip was.  Not just sympathetic, pip was large at heart. He was generous. This can be witnessed in page _____ where he secretly buys Herberts way into business. The third example to show that pip was generous is in page 137where he says, as I passed the church I felt a sublime compassion for the poor creatures who were destined to go there, Sunday after Sunday, all their lives thru and to lie obscurely at last among the low green mounds. I promised myself that I would do something for them one of these days and formed a plan in outline for bestowing a dinner of roast beef and plum pudding, a pint of ale and a gallon of condescension upon everybody in the village. 3. Had a great desire for self-improvement: pip always wanted to better himself, better his condition and better his status. This trait in him can be witnessed in page 66 where he tells Joe, and that there had been a beautiful young lady at miss Haveshams who was dreadfully proud and that she had said I was common, and that I wished I was not common, and that the lies had come of it somehow, though I didnt know how. Moreover his deep desire to improve in life, to be Uncommon is also seen in page 68 where he goes to one of his relatives, Biddy to get educated from her. He says, when I woke up the best step I could take towards making myself uncommon was to get out of Biddy everything she knew.  In page 164 he asks Herbert to correct his mannerisms if he found them un-gentlemanly. He says, I further mentioned that as I had been brought up a blacksmith in a country place, and knew very little of the ways of politeness, I would take it is a great kindness in him i.e. Herbert if he would give me a hint when ever he saw me going at a loss or going wrong.

Examining Practice Of Price Discrimination Economics Essay

Examining Practice Of Price Discrimination Economics Essay Perfect competition is the most efficient market structure because, in the long run, each firm in the market will be producing at its minimum average cost, or per-unit. This means that consumers get desired goods and services at the lowest possible prices, and also that the firms are economizing on societys scarce resources to the greatest extent possible. What is the difference between the concepts of diseconomies of scale, and the law of diminishing return? (4 marks) Law of diminishing return occurs in the short-run when one factor is fixed. If the variable factor of production is increased, there comes a point where it will become less productive and therefore there will eventually be a decreasing marginal and then average product. When long-run average total cost rises as output increases, there are said to be diseconomies of scale. a. Sally owns a ceiling fan company. Last year, she sold 1000 ceiling fans at $50 each, and each fan cost her $20. Before going into the ceiling fan business, she worked as a fan-dancer at $25,000 a year. She used her own money to buy the fans by withdrawing the money from her savings account where it was earning five percent annual interest. Calculate Sallys economic profit and her accounting profit. Should Sally continue with her ceiling fan business? Explain. (6 marks) If her economic profit is at least zero, Sally should stay in business. Her TR = $50,000 and her total accounting cost is $20,000, for an accounting profit of $30,000. She forgoes interest on savings of $20,000 (.05) = $1,000 as well as forgone earnings of $25,000. This leaves $4,000 in economic profit, so she should stay in business. Bob Edwards owns a bagel shop. Bob hires an economist who assesses the shape of the bagel shops average total cost (ATC) curve as a function of the number of bagels produced. The results indicate a U-shaped average total cost curve. Bobs economist explains that ATC is U-shaped for two reasons. The first reason is the existence of diminishing marginal product, which causes it to rise. What is the second reason? Explain your answer. Assume that the marginal cost curve is linear. (4 marks) Average fixed cost always declines as output rises because fixed cost is being spread over a larger number of units, thus causing the average total cost curve to fall. a. Provide two circumstances in which monopoly may offer efficiency advantages over competition. (4 marks) A monopolist might be better positioned to exploit economies of scale leasing to an equilibrium which gives a higher output and a lower price than under competitive conditions. As firms are able to earn abnormal profits in the long run there may be a faster rate of technological development that will reduce costs and produce better quality products for consumers. This is because the monopolist will invest profits into research and development to promote dynamic efficiency. Explain the practice of tying and discuss why it is controversial. (5 marks) Tying is the practice of bundling goods for sale. It is controversial because it is perceived as a tool for expanding the market power of firms by forcing consumers to purchase additional products. However, economists are skeptical that a buyers willingness to pay increases just because to products are bundled together. In other words, simply bundling two products together doesnt necessarily add any value. It is more accurately believed to be a form of price discrimination. Describe the source of tension between cooperation and self-interest in a market characterized by oligopoly. Use an example of an actual cartel arrangement to demonstrate why this tension creates instability in cartels. (5 marks) The source of the tension exists because total profits are maximized when oligopolists cooperate on price and quantity by operating as a monopolist. However, individual profits can be gained by individuals cheating on their cooperative agreement. This is why cooperative agreements among members of a cartel are inherently unstable. a. If the average total cost curve is falling, what is necessarily true of the marginal cost curve? If the average total cost curve is rising, what is necessarily true of the marginal cost curve? (5 marks) When average total cost curve is falling it is necessarily above the marginal cost curve. If the average total cost curve is rising, it is necessarily below the marginal cost curve. Describe the difference between average revenue and marginal revenue. Why are both of these revenue measures important to a profit-maximizing firm? (5 marks) Average revenue is total revenue divided by the amount of output. Marginal revenue is the change in total revenue from the sale of each additional unit of output. Marginal revenue is used to determine the profit-maximizing level of production and average revenue is used to help determine the level of profits. Describe the process by which the market for capital and the market for land reach equilibrium. As part of your description, elaborate on the role of the stock of the resource versus the flow of services from the resource. (6 marks) Equilibrium in the markets for land and capital are governed by the value of marginal product for these factors relative to their supply. One difference between these markets and the market for labor is the distinction between rental value (flow) and purchase price (stock). This difference is reconciled by noting that in efficient markets, the purchase price should reflect the value of the stream of services provided by the land or capital (or the sum of rental values appropriately discounted). a. List and explain two conditions necessary for firms to be able to successfully practice price discrimination. (2 marks) Differences in price elasticity of demand between markets: There must be a different price elasticity of demand from each group of consumers. The firm is then able to charge a higher price to the group with a more price inelastic demand and a relatively lower price to the group with a more elastic demand. By adopting such a strategy, the firm can increase its total revenue and profits. To profit maximize, the firm will seek to set marginal revenue = to marginal cost in each separate (segmented) market. Barriers to prevent consumers switching from one supplier to another: The firm must be able to prevent market seepage or consumer switching defined as a process whereby consumers who have purchased a good or service at a lower price are able to re-sell it to those consumers who would have normally paid the expensive price. This can be done in a number of ways, and is probably easier to achieve with the provision of a unique service such as a haircut rather than with the exchange of tangible goods. Seepage might be prevented by selling a product to consumers at unique and different points in time for example with the use of time specific airline tickets that cannot be resold under any circumstances. Explain how each of the following industries practices price discrimination: (6 marks) restaurant Restaurants sometimes have childrens menus. It can be profitable if adults who come to restaurants with children are, on the average, more sensitive to prices on menus than adults who come to restaurants without children. Children often do not value restaurant food and service, and often waste a large part of their food. Parents know this and do not want to pay a lot for their childs meal. If restaurants treat children like adults, the restaurants may lose customers as families switch to fast-food restaurants. If this explanation is correct, then restaurants price discriminate. airline Airlines charge different prices for seats on the same plane, depending on when the ticket was purchased, how long the traveler will be staying at the destination, etc. Of course, the cost of operating the plane is independent of these variables. Hairdresser A hairdresser may charge a lower price to children than to adults. The reason they do this is that they believe children to have a differing elasticity of demand to adults. In other words, the price needed to maximize revenue from children is not the same as the price needed to maximize revenue from adults. By charging different prices they will maximize revenue from both groups Calculate the total revenue without price discrimination as well as with price discrimination, and complete the table with your calculations. (4 marks) Price Qd TR TR (with perfect price discrimination) 30 0 22 10 220 220 14 16 224 304 10 24 240 464 7 38 266 562 Briefly describe the characteristics of each of the following market types. Give an example of each market type. (8 marks) pure competition The goods being offered for sale must all be the same. The buyers and sellers must be so numerous that no single buyer or seller influences the market price. Buyers and sellers are price takers. An example would be the wheat market. Monopoly A monopoly is a market in which there is only one seller and the seller sets the price of the product, given the demand curve for that product. An example would be a local cable television company. Oligopoly An oligopoly is a market in which there are only a few sellers, and the sellers do not always compete aggressively. An example would be airline routes. monopolistic competition Monopolistic competition is a market containing many sellers offering slightly different products. Because the products are not the same, sellers have some ability to set price. An example would be the software industry. Use the graph below to explain why a profit-maximizing monopolistically competitive firm must operate at excess capacity. Why is a perfectly competitive firm not subject to the same constraint? (6 marks) Competitive firms do not face downward-sloping demand. The graph shows the firm choosing a level of production in which the intersection of marginal revenue and marginal cost occurs at an output level where average total cost is decreasing. This profit-maximizing output level is less than the efficient scale (minimum of average total cost) and therefore the firm is said to be operating at excess capacity. If the monopolist depicted in the graph below sets a price of $10 and sells 100 units, the corresponding marginal revenue is $5 and marginal cost $3. What recommendation regarding price and quantity would you give this monopolist? Explain your answer. (6 marks) Since MR exceeds MC, recommend an increase in output. Greater sales will require a price reduction. So reduce P below $10 and increase Q above 100. The marketing division of a firm has measured demand for its product and reports that it is Q = 24 P, where Q is units and P is price per unit in dollars. The cost is given in the table below. Complete the table and determine the profit-maximizing level of output for this firm. (6 marks) As indicated in the table below, the optimal output is Q = 5, where MR = MC = 5.80. Output Total Cost Price Revenue Profit 0 10 24 0 -10 1 18 22 22 4 2 20 20 40 20 3 22 18 54 32 4 25 16 64 30 5 29 14 70 41 6 34 12 72 38 7 40 10 70 30 8 48 8 64 16 Define the following terms and explain their importance to the study of economics. (9 marks) barriers to entry Barriers to entry make it difficult or impossible for other firms to enter an industry, thus allowing monopoly to continue to exist. Some examples of barriers include legal restriction on entry, patents, control of scarce resources, large sunk costs, technical superiority, and economies of scale. Patent A patent is a government-granted legal monopoly given to the inventor of a new product or process. During the life of the patent, the firm has a protected monopoly position. Thus, it serves as a barrier to entry. natural monopoly A natural monopoly is an industry in which advantages of large-scale production make it possible for a single firm to produce the entire output of the market at lower average cost than a number of firms each producing a smaller quantity. Most natural monopolies are regulated utilities.

Personal Strengths and Weaknesses Essay -- essays research papers

Personal Strengths and Weaknesses What are my personal strengths and weaknesses? When I think about this question, the first thing that comes to mind is a job interview. I, like most people, find this simple question to be the most stressful moment of any interview. I want to give an answer that is imaginative but does not give the interviewer a bad impression of myself. In this paper, I will describe my strengths and weaknesses as I would to a job interviewer. I will give specific examples of my strengths and place a positive spin on my weaknesses. When deciding which strengths you want describe to an interviewer, you should make a list, choose three to five of those strengths that match the job posting, and give specific examples of that strength (Martin, 2005). I can easily tell you that my greatest strengths are the core values that I was instilled with during my service with the United States Air Force. Integrity first, service before self, and excellence in all [I] do (USAF, 1997); these are my strengths that I bring to every job or task I do. Integrity first refers to a willingness to do what is right, even when no one is looking (USAF, 1997). Integrity also means optimizing your job tasks and assisting coworkers in optimizing their job tasks. For a manager, integrity is motivating your team so that they understand the importance of their job so that they are willing to do their jobs, even when you are not looking. Service before self refers to the fact that professional duties take precedence over personal desires (USAF, 1997). In the business setting, service before self means finishing tasks or jobs before you go home at the end of your shift and not leaving them for someone else to finish up. If it is Friday afternoon and I have been given a task, I will always finish my job then, even if it means starting my weekend late. Service before self also means that you should never call in to work just because you do not feel like coming in. I have never taken a personal day at any job I have ever worked. Excellence in all [I] do refers to the development of a sustained passion for continuous improvement and innovation (USAF, 1997). One example of this is my attending the University of Phoenix; I wish to improve my job skills and marketability. In the business setting, this also means that if there is ever a task that I did not complete to the stan... ...eople for the first time. Interpersonal skills, like any skills, will only improve with practice and feed back. One nice aspect of my current position is that it requires me to speak with new people on a daily basis to accomplish my job assignments. I also get a chance to practice my interpersonal skills while attending the University of Phoenix. With every new class I enter, I am required to deal with new people in different settings. In summary, assessing strengths and weaknesses during a job interview is something that no one should take lightly. By giving my interviewer a well thought-out response, I can let the interviewer know more about myself and help he or she see that I am the right fit for the job. By letting my interviewer know about my weaknesses, I let him or her know that I am not perfect but that I am continually working to improve myself (Martin, 2005). References Martin, L. (2005).
