MIMO Wireless Channel and How to Determine Its Capacity...

‘‘If I have seen farther, it is by standing on the shoulders of giants.’’ is very truly coated by Sir Isaac Newton. Ideas gave way to idea. When Marconi invented wireless communication 100 years ago, we had no idea that one day life will seem to be impossible without it. It has penetrated each and every aspect of human life and has resulted into endless demands on bandwidth and spectrum. And by standing on the shoulders of giants, Teletarand Foschinigave the technique of MIMO system which would increase the spectral efficiency of the wireless system to its maximum compared to all the current technologies. Multiple antennas are used for transmission and reception to increases the capacity of the wireless channel.Capacity is expressed as the†¦show more content†¦SIMO Fig1: Different antenna configurations in space-time systems. Now we know that MIMO is an array, so we need to be some terms related to antenna array, which is Array gain, the average increase in the signal-to-noise ratio (SNR) at the receiverthat arises from the coherent combining effect of multiple antennas at the receiveror transmitter or both.If the channel is known to the multiple antenna transmitter, The transmitter will weigh the transmission with weights, depending on the channelcoefficients, so that there is coherent combining at the single antenna receiver.The array gain in this case is called transmitter array gain. And vice versa for SIMO case, which will be known as receiver Array Gain. Basically, multiple antenna systems require perfectchannel knowledge either at the transmitter or receiver or both to achieve thisarray gain. Next important term is Diversity Gain. Multipath fading is a significant problem in communications. In a fading channel,signals experience fades.When the signalpower drops significantly, the channel is said to be in a fade. This gives rise tohigh bit error rates (BER).This involvesproviding replicas of the transmitted signal over time, frequency, or space. Thereare three types of diversity schemes in wireless communications: I .Temporal diversity: In this case replicas of the transmitted signal are provided across time by a combination of channel coding and time interleaving strategies.Show MoreRelatedEvaluating A Resource Allocation Scheme For Coordinated Multi Point1517 Words   |  7 Pagessignificant gains in terms of the overall capacity of cell and cell-edge user throughput.

The Bloody Chamber, By Angela Carter - 1386 Words

As a feminist, it is almost to be expected that many of Angela Carter’s happy ever after endings will strike the reader with a bold feminist message. However, in The Bloody Chamber, this is not necessarily the case. Although there are several feminist messages in the stories’ resolutions, these messages are not always presented in the way one would expect, and not every female protagonist is presented as a feminist character. By taking the roles of typically Gothic women and toying with the presentation of female characters, many of Carter’s feminist messages are not as one would expect. The eponymous story The Bloody Chamber ends with a sense of resolution, love and happiness. The antagonist of the story is no more, and the narrator is able to live a happy and fulfilling life with Jean-Yves. Whether the ending is truly feminist, however, is open to discussion. In one respect, the actual resolution to the story is all down to the narrator’s mother, who is presented at the story’s climax as an incredibly powerful female figure. Carter uses masculine and bestial imagery to describe the mother, in a way that is not dissimilar to earlier imagery to describe the Marquis. The narrator refers to her mother’s hair as â€Å"her white mane†; just as earlier she had referenced the Marquis’s â€Å"dark mane†.

Southwest Airlines Business Model free essay sample

The airlines industry has historically been one of the most unprofitable industries. The reason can be explained when incorporating Michael Porter’s famous Five Forces Model. The threat of competition is Southwest Airlines Co. (NYSE: LUV) is an American low-cost airline based in Dallas, Texas, with its largest focus city at Las Vegas McCarran International Airport. It is the largest airline in the United States by number of passengers carried domestically per year and (as of December 31, 2007) also the largest airline in the world by number of passengers carried. It is also the 6th largest U.S. airline by revenue. [8] It also maintains the third-largest fleet of aircraft among all of the worlds commercial airlines. As of July 12, 2008, Southwest operates approximately 3,500 flights daily. Southwest Airlines has carried more customers than any other U. S. airline since August 2006 for combined domestic and international passengers according to the U. S. Department of Transportation’s Bureau of Transportation Statistics. [9] Southwest Airlines is one of the worlds most profitable airlines and in January 2008, posted a profit for the 35th consecutive year. Southwest Airlines was originally incorporated to serve three cities in Texas as Air Southwest on March 15, 1967, by Rollin King and Herb Kelleher. According to frequently-cited story, King described the concept to Kelleher over dinner by drawing on a paper napkin a triangle symboliziSouthwest Airlines founder Herb Kelleher studied California-based Pacific Southwest Airlines extensively and used many of the airlines ideas to form the corporate culture at Southwest, and even on early flights used the same Long Legs And Short Nights theme for stewardesses on board typical Southwest Airlines flights. The airline adopted the first profit-sharing plan in the U. S. airline industry in 1973. Through this plan and others, employees own about 10 percent of the company stock. ng the routes. (Dallas, Houston, San Antonio)[11] he rest of 1971 and 1972 saw operating losses. One of the four aircraft was sold to Frontier Airlines and the proceeds used to make payroll and cover other expenses. Southwest continued to operate a schedule predicated on four aircraft but using only three, and in so doing the ten minute turn was born, and was the standard ground time for many years. 16] Southwest turned its first annual profit in 1973, and has done so every year since — a record unmatched by any other commercial airline. Southwest has used financial techniques such as fuel hedging to bolster its profitability and counteract many of the fiscal disadvantages of operating an airline. Fuel cost containment measures Southwest Airlines earned a reputation for being very aggressive and proactive about containing fuel costs as a key to maintaining profit margins. [19] With fuel being an airlines most important variable cost, Southwests measures have become a model for the industry. Hedging fuel Southwest has a longtime program to hedge fuel prices. It has purchased fuel options years in advance to smooth out fluctuations in fuel costs. In 2000, Southwest said it had adjusted its hedging strategy to utilize financial derivative instruments when it appears the Company can take advantage of market conditions. Additionally, the company hoped to take advantage of historically low jet fuel prices. SEC statement Southwests decision proved to be a prescient and, for a time, extremely profitable effort. To lock in the low historical prices Southwest believed were occurring at that time, Southwest used a mixture of swaps and call options to secure fuel in future years while paying prices they believed were low. The company also stated that with this new strategy, it faced substantial risks if the oil prices continued to go down, but they did not. Previously, Southwest had been more interested in reducing volatility of oil prices. Now, they hoped to reap large gains from oil price appreciation. In 2001, Southwest again substantially increased its hedging in response to projections of increased crude oil prices. The use of these hedges helped Southwest maintain its profitability during the oil shocks related to the Iraq War and later Hurricane Katrina. According to an annual report, here is the companys fuel hedge for forward years (approximate per barrel basis, as of mid-January): 2007 is 95% hedged at $50/barrel; 2008 is 65% hedged at $49/barrel; 2009 is over 50% hedged at $51/barrel; 2010 is over 25% hedged at $63/barrel; 2011 is over 15% hedged at $64/barrel; 2012 is 15% hedged at $63/barrel. According to its 2006 Annual Report, Southwest paid low prices for fuel thanks to the benefit of fuel hedges: †¢2004 82. 8 cents/gallon †¢2005 103. 3 cents/gallon †¢2006 153. 0 cents/gallon These are well below market rates, which Southwest factors into its low operating costs. However, this below-market oil cost will not continue forever; executives have said that Southwest faces increased exposure to the raw oil market every year. This is not a good sign for the airline, which is also facing tough competition from US legacy carriers that have lowered costs through bankruptcy. Southwest CEO Gary Kelly has decided to slow the airlines growth as a response to this cost. Some analysts have argued against the style of profit-motivated energy trading Southwest did between 1999 and the early 2000s. They suggested that rather than hedging business risk, (such as a hedge on weather to a farmer), Southwest was simply speculating on energy prices, without a formal rationale for doing so.

What are the strengths and weaknesses of Intuitionism Essay Example

What are the strengths and weaknesses of Intuitionism Paper Intuitionism came about as a post-utilitarian perspective, and was largely developed as an ethical theory by Moore, Pritchard and Ross. As the name of the theory tells us it is concerned with humans intuition, Sidgwick came to the conclusion that ethics was not based on a unifying principle but rather on human intuition. Today, an intuitionist is thought of as someone who holds particular views about the way in which we come to find out what actions are right and which are wrong. Apparently, we group basic moral principles because of our intuition. Moral principles are capable of being true and known through a special faculty; moral intuition. W. D. Ross and Pritchard, claimed that they are facts about what is morally right and wrong and that our understanding of these is sufficient to deserve the title knowledge. We know that something is good by intuition: it is self-evident, good is something known directly by intuitionism1 G. E. Moore wrote that what is good, or morally good, cannot be defined by humans, just as yellow also cannot. We all know what yellow is in sensory terms but the only way to describe yellow is to use other colours which does not help someone who is colour blind, Good can be defined no more successfully than yellow. 2 However, we know instantly what yellow is, and we know instinctively what is morally good; they are both self-evident to us. Moore thought that what makes an action good or otherwise are the aims of the person in question when carrying out that action. Moore then went on to make a distinction between the aims and the consequences of an action: the aims are decided intuitively before the action and determine its moral nature.

Harold Arthur Pritchard developed Moores ideas further, he thought that moral obligation just is, and it can be perceived by our intuition. This means that moral obligation is something that a person could just know, it was not quite the same as feeling certain or failing to think or not questioning. The most evident strength of intuitionism is that the Judaeo-Christian tradition teaches that human beings are made in the likeness of God, therefore having his laws written in their hearts. This clearly supports the intuitive approach. The good person knows what is morally good because he/she is designed to know. Paramount to this idea is a) there is an absolute moral code b) that we have the ability to recognise it. Moreover, it is likely in practice that the majority of moral agents act at least partly from intuition on the majority of occasions when they have to make a moral decision. A weakness of the system is to assume that we can know A because of B. We cannot, in fact, say something is right because we intuit it to be that way. An intuitionist would say that humans only have their moral hunches and intuitions to guide them, so we have to rely on this by default. Unlike the scientific world in the world of morals, an intuitive moral decision is often held to be right because the person feels it to be so. This can be seen as a criticism of intuitionism because moral decisions making is more of an art form that an exact science. The apparent weaknesses of intuitionism could be summed up by saying when asking why should I be good? Because you just know you should. Emotivism, as its name suggests, is the moral theory based on peoples emotive responses to other people, events, situations, viewpoints and principles. Emotive response in this context is simply referring to a persons feelings about something. Thus, Emotivism is concerned principally, if not exclusively, with how people feel about something. This can be clearly seen in someone who says abortion is wrong, because according to Emotivism all they are doing is announcing how they feel about abortion. Even if they give a number of reasons why they feel this way, for example it goes against the sanctity of life. All the person is doing is finding other reasons which appeal to their emotions in order to support their initial position. When we remove all the so called rational reasons or arguments for doing A rather than B or believing in X rather than Y, then at root what we are left with is just a personal preference based on feelings of approval or disapproval. This is why the theory is commonly known as the Boo-Hurrah theory; when a statement is approved of the response is Hurrah and when a statement is disapproved of then the response is Boo. The weaknesses of the emotive theory of ethics are as follows; most people believe the need for a moral code. Most moral codes prescribe anti-social acts such as murder, stealing, cheating, deceiving, offending others. Integrity, honesty, loyalty, decency are also common moral requirements. If there is such a thing as a basic moral code, then Emotivism which is relative cannot be an exhaustive or complete system. Also, if everyone operates morally solely on their emotions then there should never be the problem of what to do, they would simply follow their strongest feeling on the issue. However, reality is different. For example; I may have huge sympathy for an elderly patient in pain, imploring me as her doctor to put her out of her misery. I have to force myself against my feelings, reasoning that her life is sacred, and I have no right to play God. Another problem with the relativism inherent in Emotivism is the difficulty of deciding where to draw the line of tolerance. If a Satanist is preaching hatred or murder as a good thing in his eyes should he be opposed vociferously, or in any other way, or not at all? After all, if he feels the emotion of hatred is the best basis of his moral code; from an emotive-relativist point of view I should do nothing unless he actually harms someone. Moreover, Alasdair McIntyre believes that Emotivism is bankrupt as an ethical theory because it lacks any moral absolutes. According to McIntyre the implications of Emotivism on society would be that social relations become manipulative because each person relates to everyone else morally in terms of their own individual emotions, not in terms of absolute moral values. This leads to people being a means to our own ends, instead of being ends in themselves.

A Linear Regression Analysis of Product

A Linear Regression Analysis of Product The researcher hypothesized that the time taken to polish a product depended on the size of the product. A linear regression analysis showed that the relationship was significant, F(1)= 54.87, p.001. There was a strong, positive, linear correlation between the size of the product and the polishing time, r=.70.Advertising We will write a custom assessment sample on A Linear Regression Analysis of Product specifically for you for only $16.05 $11/page Learn More As expected, the time taken to polish a product depended on the size of the product. A scatterplot (shown below) was produced to determine the suitability of the model, where the scatterplot of the two variables showed that a linear model was suitable in this situation. Figure 1: A scatter plot for time of polishing against diameter of product There is a linear, positive relationship between the time that is spent polishing a product and the size (diameter) of the product, as shown in the scatterplot. It means that one of the assumptions for carrying out a regression analysis has been met. Although there seem to be some outliers in the scatter plot, they cannot be considered as significant outliers. It implies that the regression equation can predict most of the values; thus, the regression model is sound. The R2 value of 0.49 indicates that 49% variability in time spent in polishing the product can be explained by the diameter of the product. Model Summaryb Model R R Square Adjusted R Square Std.

In this case, the ANOVA report provides information that helps in showing how well the regression equation predicts the time spent in polishing the product. The ANOVA report for the time of polishing and the diameter of the product shows that the regression model predicts the time spent on polishing the product significantly well because the F value is significant, p.05. In other words, the regression model is significance p=.001 and its fit for the data. Coefficientsa Model Unstandardized Coefficients Standardized Coefficients t Sig. B Std.

Dependent Variable: time The Coefficients table is necessary because it is a report that gives information that helps in predicting the dependent variable from the independent variable. In this case, the coefficients table gives information that helps in predicting the time to be taken to polish the product from the diameter of the product. The table also helps in determining whether the independent variable contributes to the model in a statistically significant manner (Linear Regression Analysis on SPSS 2015). In this case, the diameter of the product contributes to the model significantly as the B value is significant, B=.564, p.05. The regression equation is derived from the coefficients table, where the dependent variable= B value of the constant+ B of the independent variabl e*independent variable i.e. Time of polishing = -1.955+ 3.457(diameter). The residuals statistics are values of the regression line, which help to determine whether the errors are near normal distribution. The residuals, also known as the errors, are the differences between the observed values and the predicted value of the dependent variable (Weinberg Abramowitz 2008). The errors in the time for polishing represent the instant analysis. In the present scenario, the errors are not large, meaning that the model is suitable for the data.Advertising We will write a custom assessment sample on A Linear Regression Analysis of Product specifically for you for only $16.05 $11/page Learn More The histogram helps in determining whether the data observes normal distribution. In other words, it checks the normal distribution of the data, which is one of the assumptions that are taken when conducting a regression analysis (IDRE 2015). In the present scenario, the his togram shows that the data largely observes normal distribution, as the data that lies on the left side of 0 is the same as that on the right side of 0. The normal distribution presented by the histogram shows that the regression model is suitable for this data, as it is one of the assumptions that should be met prior to conducting a linear regression analysis. Figure 2: A histogram with a standard curve showing the distribution of polishing time The results of the regression analysis can be used to improve the operational efficiency of Nambe Mills and reduce the operations cost. Nambe Mills can lessen the time by making products of smaller sizes, given that the time of polishing increases as the product size increase. This would save time and resources employed in polishing the product and channel the resources into other areas of operations. The company could assign more personnel to the role of polishing the products that are larger in size, given that they take more time to pol ish. The company can use the regression equation, Time of polishing = -1.955+ 3.457(diameter), to determine how much time it would require polishing any given item.

Visual rhetoric paper Essay Example | Topics and Well Written Essays - 3250 words

Visual rhetoric paper - Essay Example This can be done by direct action - force, threats, bribes, for example - or it can be done by the use of "signs", of which the most important are words in speech or writing" (Kennedy, 3) As we may notice, this definition doesn't exclude the possibility of using other types of signs than those commonly used, the linguistic signs. On the contrary, it implies the fact that rhetoric uses more than a system of signs. Newer approaches on rhetoric, as well as the broader definition of rhetoric as "the totality of connotators" (Barthes, 38) - connotators being the signifiers of connotation that correspond to the general ideology - place the image at the centre of a system of signs. Image is seen as able of conveying meaning and expressing ideas as well as having a persuasive function. Advertising images are the best illustration of the second function. They don't just denote, but they have very much to do with the connotation function. An image showing a mother and a little child sleeping peacefully, and a bottle of milk on the table near the bed, is meant to suggest that the peace of their sleep is a result of their drinking the respective brand of milk that contains everything necessary both to the adult and to the child's health. And it is meant, of course, to persuade us buy the respective brand of milk. ... Art has always been seen as more than a representation of reality. With its images, it's more difficult indeed to identify the message or the meaning, but there is no doubt, a message or a meaning is present. In fact, there is always more than one meaning attached to an image and that makes it almost impossible for us to exhaust the interpretations of a work of art. Richard Wendorf's opinion, quoted in Defining Visual Rhetorics, is that "writers and painters have always been fascinated by the relations that serve to join words and images." (Hill and Helmers, 63) More than being preoccupied with making a connection between the written and the visual work in arts, researchers in the field of visual rhetoric are concerned with showing how the work of art itself carries meaning.In painting, images become the replacement of language. The elements of the image and the way they are placed together in order to make up the painting may be seen as similar to the way in which words are chosen and arranged in a sentence or in a text in order to convey meaning or to determine change in the surrounding environment. Only that the meaning you find in the painting is more varied than in the case when linguistic signs are used. Ernst Gombrich expressed the following: "looking at a picture can take a good deal of time", as it involves "scanning, remembering, antic ipating, correcting and confirming impressions." (Hill and Helmers, 65) So, the viewer's interpretation gives the meaning of the image. Meaning is constructed or it may be said that it is chosen from a wide variety of latent meanings which are only activated through the viewer's acting upon them. And the meaning

Improving Poor Quality and Performance Case Study

Improving Poor Quality and Performance - Case Study Example This will be tackled through a systematic plan aimed at refining its work station system with the help of scientific management basically aimed at the productivity of line managers. This is due to the fact that the company is basically a factory that depends on the effectiveness of its line managers. The company that will be dealt with in this paper is the Anukul Group. This company basically manufactures exclusive designer furniture, stained glass and patchwork linen. It is a company owned by Dipti Mahapatra in India and has been in the business for close to two decades. Having started in the year 1988, this company started out as a small unit with four tailors and has now gone ahead to become one of the most prestigious names in interior decoration in the state of Orissa. The demand for Dipti's products grew and there was a market for interior decoration. By 1993, Dipti was busy undertaking several turnkey projects for complete furnishing of guest houses, hotels, as well as the Governor's residences in the state of Orissa. Developed by Frederick W Taylor in the early 20th century, Scientific Management is a science based system of organizing the operational areas of the organization so as to ensure the existence of and implement the following elements: (Wrege, 1995) To create room for four to eight functional foremen who will take care of various aspects of the overall task, so as to ensure that each sub task is carried out as regards minimum motion and cost per worker. (Taylor, 1947) These were the broad underlying principles upon which F W Taylor fashioned scientific management. This school of management thought followed experimentation and scientific rigor to demonstrate various findings. One of these, as will be tested below, adheres to the fact that through mediums like assembly line, it is possible for a group of people doing a few tasks, to out produce those doing all the tasks. Improvement of Quality and Performance Anukul Designs is a company that has been in the business of manufacturing exclusive patchwork linen, for the last 20 years. The assembly line followed in this

Social Dimensions of Child Abuse in KSA Essay Example for Free

Social Dimensions of Child Abuse in KSA Essay First of all, I wish to laud you for having tackled these important aspects of the problem you wish to do research on: You have an excellent grasp of long-term outcomes, policy changes (p. 7) Acknowledging that some baseline research has already been done (p. 5) Difficulties (p. 6), really Limitations which you must address by recommending suitable methodology Research objectives (p. 6) May I suggest you restructure in this fashion? INTRODUCTION/BACKGROUND One paragraph on â€Å"why should we be concerned about child abuse?† One long paragraph on historical prevalence (cite authoritative sources, including those that have parallels to the domestic/family/society practices in KSA). One (long) paragraph on the moral and policy framework espoused by international organizations (e.g. UNICEF?) The child abuse prevalence, social philosophy and policy framework in selected countries (It is good to cite the U.S. but are there others? Notably Muslim ones?) Please consider moving the sentence at the bottom of page 3 here. It’s an effective recap. REVIEW OF LITERATURE You have ten references lined up in the bibliography.   Why not do justice to your research by summarizing what you’ve found in them?   Perhaps in this sequence? Prevalence of child abuse in KSA and other Muslim societies Types of child abuse committed in KSA Why it may be under-reported. (This is where the current content of â€Å"Difficulties of the study† really belongs. Cite sources.) The social factors behind child abuse Social, religious and policy support for combating child abuse in KSA. What legal support is there for intervening in domestic cases of child abuse, for treating both abuser and victim?   In any society, physicians would be hamstrung if laws did not exist to mandate reporting of abuse and penalties for offenders.   Everybody would just sweep things under the rug. How victims are aided/helped and offenders treated What information gaps still exist? IMPORTANCE OF THE STUDY Then you’d bring in the pioneering role of KFSHRC here to affirm that some organization is doing something about child abuse but (point G. above) there remain information gaps that must be addressed if effective remedial measures are to be proposed. RESEARCH PROPOSAL PROPER Research Objectives Revise, expand or tone down according to what you have already found in Review of Literature above. 4th bullet point: replace â€Å"volume† with â€Å"incidence† or â€Å"prevalence† 5th and 6th bullet points: move to â€Å"OUTCOMES† below Consider taking out the 7th point, this involves you in doing longitudinal studies. Last bullet point: please consider re-writing to make it more specific or measurable, e.g., â€Å"Formulating – via professional consensus – a structured process for resolution, therapy and general management of abuse patients and offenders†¦.† Type of Study Considering the ticklish social situation you speak about, please think about augmenting your methodology with qualitative methods, e.g., focus groups, depth interviews and projective techniques. Target Respondents The seven points you made at the top of page 6 work better here to help shape your considerations (or rationale) for tackling different types of respondents and the data-gathering approach suitable for each one. Consider adding educators to your sample.   Not all child abuse cases result in physical trauma and not all traumas are reported to pediatricians either.   Do you have something like social welfare workers in KSA?   They might be a good source, too. Study Instruments Under Questionnaire, â€Å"This questionnaire consists of several parts† I think what you really mean is that you plan to create different versions depending on whether you’re interviewing physicians, parents, abused children or adults who can tell you about having been maltreated as children.   I believe you want to tread carefully about promising to interview abused children, this is one of the most challenging â€Å"discovery/disclosure† type of sessions counselors have to undertake. OUTCOMES This is where your statements on pages 6 and 7 belong. Your situation strikes me as one of advocacy, i.e., you want to provide a firmer basis for recognizing the problem, for professionals to take action and for government to provide legislative support.   You might also co-opt Sharia, if Koranic law has anything to say about child abuse. A FINAL NOTE: I’m not sure what â€Å"missing paragraphs† you allude to, that’s why I sent the earlier message.   The way we work, in any case, supplemental writing would be covered by filing a second order of the â€Å"Edit† type.   This is a â€Å"Review† order.   Good luck.   Hope all the above have helped.

The Catcher In The Rye :: essays research papers

Holden’s Journey   Ã‚  Ã‚  Ã‚  Ã‚  As we pass through this life it is our duty to discover our destiny. Some of us go to college and become Doctors, Lawyers, Architects. Others of us cherish the finer things in life and find our places on farms and Dude Ranches. The point is, every living creature has a place in this world and we are ultimately steered in its direction. Holden Caulfield’s voyage began when his brother died of Leukemia. Holden was emotionally destroyed by the loss of not only his brother, but his best friend also. The fact that his parents couldn’t accept Holden’s pain and that they even sent him to a shrink for it, proved to Holden that his parents didn’t care as much as they were supposed to.   Ã‚  Ã‚  Ã‚  Ã‚  As Holden grew up, he found himself flunking out of school after school, never being able to stay in one place. This calamity was caused by either his overwhelmingly powerful hatred for people or because there was a conflict of interest between him and the school itself, about who they were trying to make him. Holden was also starting to view people as who they really were. Many of us in this world accept people at face value and never really take the time to see through the infinite masks that make up a personality, or a first impression. Holden however, took the time to understand who a person really was, and how fake they really were being. This changed his life enormously, as it would anybody’s, because as soon as he could understand how much of a phony a person was being and who they truly were, he didn’t have to feel inferior, scared or cast out by that person. I think these views of life could have actually been caused by his brother’s death. I think that when his brother died, his parents might have become phonies themselves. You must understand that when a parent loses one of their own creations they feel as if they have lost a part of themselves and cannot strive to go on. I think many parents find it easier to conceal their feelings inside of themselves, thus becoming what Holden could view as a phony. He didn’t understand why his parents had to bottle it all up (which he thinks is wrong) and why he was almost punished for expressing his feelings freely (which he feels is the right thing to do).

Raising the Driving Age

For at least the last ten years, the issue of whether or not to raise the driving age to 18 years old has been a touchy subject on every level of the spectrum; from State Highway Safety Association to teenagers and everybody in between. Although everyone has some degree of approval that raising the driving age would be a good idea no one has really put forth the effort to actually have it come to pass. This has lead to the ongoing debate of whether it should even be a consideration anymore.There are several reasons that establishing the driving age at 18 is a legitimate idea. First, by having the driving age moved to the minimum of 18 this can be both environmentally and economically commendable. Also, teenagers under the age of 18 are more mentally underdeveloped when it comes to making sound decisions on the road, which then leads teenagers to having one of the highest fatality rates involving automobiles. Global warming has become key issue all over the world, especially in more o ver-crowded counties and cities, due to higher volume of emissions being released into the air.In the year 2000, the Carbon Emissions that are released into the air by cars in the United States is 302 Million Metric tons (MMTc) (Environmental). In that same year, there were 190 million licensed drivers in the United States, and 9,743,000 were drivers under the age of 19 (U. S), that’s five percent of the population. I know it doesn’t seem like that much but when you take in consideration the total emissions being released into the air and multiply it by the number of teenage drivers, that will reduce the amount of emissions by 15. MMTc. People are desperate to help stop global warming; one way we can do this is to reduce the amount of drivers on the roads and create a more accessible public transportation in rural areas. Increasing the age for driving would also be beneficial to parents of teen drivers due to the fact that insuring a teen driver is very expensive. A re cent study, in 2009-2010 for a one-car family to insure their teen-driver would raise their premium 42 percent, 58 percent for a two-car family and 62 percent for a three-car family (Schultz).An average of $620 dollars a year is what parents pay to add their child to their insurance (Bradford). That is one child, I come from a family of five and eleven years ago, when I turned sixteen my parents already had two teen drivers on their auto insurance and we were living off two teacher salaries. By the year 2000 the average teacher in Texas was making 37,576 (IES); that would leave them with a combined income of just over 75 thousand a year.Paying an average of $620 dollars per teen driver wouldn’t have gone over well with living expenses, so needless to say, I got my divers license but I wasn’t able to drive until I was 18. There are always two sides to an argument, Parents grow weary of driving their kids for one place to the next; interrupting their own busy schedules t o drive their teen to their next social event. Bill Van Tassel, AAA’s National manager for driving training programs says â€Å"We have parents who are pretty much tired of chauffeuring their kids around, and just want them to be able to drive† (Davis).This is completely understandable, with today’s busy world no one has time for anything but does it really merit putting a population of underdeveloped minds behind the wheel for our own convenience? Which brings me to my next point; are teens mentally mature enough to be granted with the responsibility of driving a car? In 2005, new findings in brain research at the National Institutes of Health explain why efforts to protect teen drivers usually fail. The scientists at the NIH in Bethesda, Md. have found that a part of the brain that weighs risks, makes judgments and controls impulse behavior which is referred to as â€Å"the executive branch† is still developing in teenage years and isn’t fully ma tured until the age of 25 (Davis). These findings should be proof alone that teens are too immature to handle the responsibilities that come with driving a car. Teens are already emotional and compulsive more so then most adults, giving them keys to a vehicle could be potentially one of the worse ideas in history.Teens don’t process consequences the same way adults do, they rely more on the emotional part of their brains to make their decisions. Which is why when a teen is driving 15 to 20 miles over the speed limit the part of their brain that processes thrill is working brilliantly; But the part that cautions of negative consequences, is all but useless, explains Jay Giedd, chief of brain imaging in the child psychiatric unit at the National Institute of Mental Health (Davis). Parents see their newly licensed teen river as additional help for running errands and taking younger siblings to events and practices, but when it comes to handling issues that may arise on the road to and from their destination; teenagers just don’t have the mental maturity to consider the consequences of risky behavior. When I was still in high school two friends of mine were bragging one morning of their reckless and very dangerous excursion across town in the pouring rain without their windshield wipers on, just because they wanted to see how far they could go.I would advocate this as a true example, that teenagers are indeed too immature and reckless to be given the responsibilities of driving. Of course one would argue that not all teenagers are as immature and irresponsible as most, in fact there are some parents that would make their teen a poster-child for safe driving; but there are always exceptions to the rules. Adolescent drivers no matter how responsible they prove themselves to be don’t have the mental development to properly react to hazardous situations that arise on the road.The research above leads to my next topic, Due to their inability to ass es dangers that come up while driving, a teen driver is more likely to be involved in or the cause of an automobile accident. In 2009, about 3,000 teens in the United States aged 15–19 were killed and  more than 350,000 were treated in emergency departments for injuries suffered in motor-vehicle crashes (CDC). With this information, one would wonder why the driving age has yet to be raised.Yet, despite the increasing number of teens dying in automotive accidents, there has yet to be a successful bill passed to raise the driving age. In September of 2008, lawmakers in Delaware, Florida, Georgia and Massachusetts introduced a bill to raise their driving age to 17; they all failed (Rubin). Some people are lead to believe that raising the driving age will not prevent teen deaths, rather just delay them, because maturity has no weight on teen driving, it’s all down to experience; It is this rational that is keeping teen drivers behind the wheel.Most states have a probatio nary period where teen must follow guidelines such as: * Night driving is prohibited for the first six months unless he/ she are accompanied by a licensed driver. * A passenger limitation of only one passenger under the age of 20 for the first six months unless a parent or guardian is present. * During the second six months only three passengers under 20 (Pabst) These restrictions have had only modest success, but with the judgment center of the teen brain not fully developed there remains a struggle to instill decision making skills in immature drivers (Davis).Most of these restrictions are left to the parents to enforce and these poorly enforced restrictions don’t seem to be helping stop the high volume of deaths due to irresponsible teenager’s being given the right to drive. In 2006, my father was killed in accident involving a teenage driver, who neglected to follow the speed limit, and disregarded the stopped school bus with its lights on, and plowed right into th e back of the vehicle behind my father causing it to hit my father on his motorcycle. I don’t know what she was doing to completely miss the big yellow stopped school bus, and the car right next to it, but it cost my father his life.The only argument against the high rate of death and injury cause by the sober mind of a teenager, are the high number of deaths caused by intoxicated driver. In 2003, 10 percent of the 16-year-old deaths in automobile accidents had a blood alcohol level of 0. 10 or higher compared to the 43 percent of 20- 49 year-olds drivers, according to the Insurance Institute for Highway Safety (Davis). The government has made it illegal to drive intoxicated to protect the lives of their people, so why can’t they raise the driving age to save even more lives?Raising the driving age is something that should be taken with the highest regard, but there are people who don’t quite understand the severity of this particular situation and would simply argue that driving there teen around is an inconvenience to them and a frustration for their teen. In actuality by having the driving age moved to the minimum for 18 can be both environmentally and economically commendable. Also, teenagers under the age of 18 are more mentally immature when it comes to making sound decisions on the road, which then leads teenagers to having one of the highest fatality rates involving automobiles.Having an understanding of the matter is very important; people shouldn’t ignore this topic just because it doesn’t fit into today’s busy and ever growing world.

Operations Management – Chapter 12

1. MRP works best if the inventory items have dependent demand.TrueFalseTRUE MRP is best for dependent demand scenarios. 2. Low level coding represents items less than $18 per unit.TrueFalseFALSE Low-level coding codes items at their lowest BOM levels. 3. Independent demand tends to be more ‘lumpy' than dependent demand meaning that we need large quantities followed by periods of no demand.TrueFalseFALSE Dependent demand is more lumpy. 4. Lumpy demand for components results primarily from the periodic scheduling of batch production.TrueFalseTRUE Batch production leads to lumpy demand for components. 5. MRP is used within most MRP II and ERP systems.TrueFalseTRUE MRP II and ERP systems incorporate MRP. 6. The master production schedule states which end items are to be produced, in addition to when and how many.TrueFalseTRUE These are critical inputs into MRP. 7. Net requirements equal gross requirements minus safety stock.TrueFalseFALSE If safety stock is required, net requirements will be higher. 8. The master schedule needs to be for a period long enough to cover the stacked or cumulative lead time necessary to produce the end items.TrueFalseTRUE This ensures that materials plans can be adequately formulated. 9. Initially, a master production schedule – the output from MRP – may not represent a feasible schedule.TrueFalseTRUE Management must make more detailed capacity requirements planning to determine whether these more specific capacity requirements can be met and some adjustments in the master production schedule may be required. 10. MRP, considering inventory position, bills of material, open purchase orders and lead times guarantees a feasible production plan if the inputs to MRP are accurate.TrueFalseFALSE MRP may lead to an infeasible production plan if capacity requirements are not considered. 11. The bill of materials indicates how much material will be needed to produce the quantities on a given master production schedule.TrueFalseFALSE The bill of materials indicates how much material will be needed to produce one unit of the item in question. 12. A bill of materials contains a listing of all the assemblies, parts, and materials needed to produce one unit of an end item.TrueFalseTRUE The bill of materials indicates how much material will be needed to produce one unit of the item in question. 13. The bill of materials contains information on lead times and current inventory position on every component required to produce the end item.TrueFalseFALSE Inventory records contain this information. 14. The inventory records contain information on the status of each item by time period.TrueFalseTRUE Inventory records also contain information on lead times and current inventory position. 15. An assembly-time chart indicates gross and net requirements taking into account the current available inventory.TrueFalseFALSE Assembly-time charts have to do with capacity, not inventory. 16. MRP II did not replace or improve the basic MRP.TrueFalseTRUE MRP II incorporates basic MRP. 17. The gross requirements at one level of an MRP plan determine the gross requirements at the next lower level continuing on down to the lowest levels shown on the bill of material.TrueFalseFALSE Released order quantities at one level determine gross requirements at the next lower level. 18.   The gross requirements value for any given component is equal to the net requirements of that component's immediate parent multiplied by the quantity per parent.TrueFalseFALSE Released order quantities for the parent lead to gross requirements of the child. 19. The term pegging refers to identifying the parent items that have generated a given set of material requirements for a part or subassembly.TrueFalseTRUE Pegging ties items to their parents. 20.   A net-change MRP system is one that is updated periodically but not less frequently than once a week.TrueFalseFALSE A net-change system is updated as transactions occur. 21. One reason that accurate bills of material are important is that errors at one level become magnified at lower levels because of the multiplication process used by MRP.TrueFalseTRUE Small higher-level errors can be magnified into larger lower-level errors. 22.   A regenerative MRP system is one that is updated continuously – every time there is a schedule change.TrueFalseFALSE Regenerative systems are updated periodically. 23. One of the primary output reports of MRP concerns changes to planned orders.TrueFalseTRUE Changes to planned orders can be outputs from MRP systems. 24.   Safety time is sometimes used in MRP rather than safety stock quantities.TrueFalseTRUE Safety time is a substitute for safety stock. 25.   Lot-for-lot ordering in MRP provides coverage for some predetermined number of periods using forecasted demand to extend beyond the orders already received for those periods.TrueFalseFALSE This is fixed-period ordering. 26.   MRP output reports are divided into two main groups – daily and weekly.TrueFalseFALSE The two groups are primary and secondary. 27. In MRP, EOQ models tend to be less useful for materials at the lowest levels than for upper level assemblies of the bill of materials since higher-level assemblies have larger dollar investments.TrueFalseFALSE EOQ is more useful at lower levels since lower-level items often have less lumpy demand. 28.   Load reports show capacity requirements for departments or work centers which may be more or less than the capacity available in that work center.TrueFalseTRUE Load reports facilitate the formulation of feasible production schedules. 29. ERP began in manufacturing organizations but has spread into service organizations.TrueFalseTRUE Over time ERP has spread into a wide variety of organizations. 30.   MRP II is simply an improved version of MRP that processes faster and can plan for a larger number of end items.TrueFalseFALSE MRP II takes into account capacity requirements. 31. Lot-for-lot ordering in MRP eliminates the holding costs for parts that are carried over to other periods.TrueFalseTRUE Lot-for-lot ordering minimizes holding costs. 32. Capacity requirements planning (CRP) is an important feature in MRP+.TrueFalseFALSE CRP is a feature of MRP II. 33. Project Management approaches can help in a conversion to an ERP system.TrueFalseTRUE ERP conversions can be complex projects. 34.   As long as a forecast is plus or minus 10%, MRP works well.TrueFalseFALSE MRP needs accurate forecasts. 35. ERP represents an expanded effort to integrate standardized record-keeping that shares information among different areas of an organization.TrueFalseTRUE ERP is intended to facilitate consistent decision-making across the organization. 36. Back flushing takes place after the production has been completed.TrueFalseTRUE Records are updated based on end-item production. 37. Before a schedule receipt can take place, and order must be placed with a vendor.TrueFalseTRUE A scheduled receipt is an order that has already been placed. 38. MRP really doesn't apply to services since raw material isn't required.TrueFalseFALSE MRP can be used in services. 39. ERP implementation requires support and a direct mandate from the CEO because it impacts so many different functional areas.TrueFalseTRUE ERP implementation is an organization-wide initiative. 40. ERP automates the tasks involved in performing a business process, such as order fulfillment and financial reporting.TrueFalseTRUE ERP extends beyond purchasing and materials management. 41. Which of the following most closely describes dependent demand?A. demand generated by suppliersB. estimates of demand using regression analysis of independent variablesC. erived demandD. demands placed on suppliers by their customersE. net material requirementsC 42. ERP implementation probably won't require:A. cross functional teamsB. just a few weeks to installC. intensive trainingD. high funding for both initial cost and maintenanceE. frequent upgrades after installationB 43.

B) the quantity of component K needed to assemble 80 units of P, given on-hand inventory of 30 A's, 50 B's and 20 C's. A) [3 Ks per C x 2 Cs per A x 2 As per P] + [2 Ks per B x 5 Bs per P] + [3 Ks per C x 3 Cs per P] = 31 Ks per P. For 80 Ps, a total of 2,480 Ks will be needed. B) With 30 As, 50 Bs and 20 Cs on-hand, K requirements are: [3 Ks per C x 2 Cs per A x (2 As per P – 30 As)] + [2 Ks per B x (5 Bs per P – 50 Bs)] + [3 Ks per C x (3 Cs per P – 20 Cs)]; for 80 Ps, a total of 2,140 Ks will be needed. Feedback: Explode the bill of material. 73. The following is a list of components required to produce one unit of nd item P: P: 2 A's, 3 B's, 3 C's A: 5 M's, 2 R's B: 1 D, 3 N's.

Assume that all lead times are one week, and that lot-for-lot ordering is used except for item F, which is ordered in multiples of 400 units. One hundred units of P should be available at the start of week 4 and at the start of week 8. Beginning inventories are: 20 P, 100 A, and 200 F. Scheduled receipts are: 800 F at the start of week 1. SEE IMAGE SEE IMAGE All items have zero balances except F, which carries 240 units forward from period 5. Feedback: Item F must be planned last. 76. Given the following data, construct a material requirements plan which will result in 100 units of Parent #1 (P1) at the beginning of week 6, and 200 units of Parent #2 (P2) at the beginning of week 8: SEE IMAGE SEE IMAGE Item A has an on-hand balance of 70 units after week 7, Item B has an on-hand balance of 150 units after week 7, and Item C has an on-hand balance of 1,500 units after week 4.

End item Alpha's product structure tree and inventory information are as follows: SEE IMAGE (A) If 50 units of Alpha are to be assembled, how many additional units of S will be needed? All parts can be ordered using lot-for-lot ordering, except M, which must be ordered in multiples of 40 units. [Hint: You don't need to do an MRP plan. ] (B) An order for 100 units of Alpha is scheduled to be shipped at the start of week 9. When is the earliest that any particular component must be started so that the order for Alpha will be ready to ship? Hint: You don't need to do an MRP plan. ] A) Gross requirements for S are 200 units, leading to net requirements for S of 100 units. B) Additional units of W will have to be started at the beginning of week 1. Feedback: If 50 units of Alpha are to be assembled, then gross requirements for K will be 50 and gross requirements for M will be 100. Net requirements for K will be 20 and net requirements for M will be 70. K is ordered lot-for-lot, so its net requirements lead to gross requirements for S of 40 units. M is ordered in multiples of 40, so its order quantity of 80 units will lead to gross requirements for S of 160 units. The longest sum of lead times is 8 (Alpha's 2 weeks + H's 4 weeks + W's 2 weeks). This means that additional units of W will have to be started at the beginning of week 1. 78.

Be specific in the situation, but do not use names or the company name. I personally have experienced age discrimination in the work place. Mostly today you hear about companies discriminating against employees over 40 because they want younger employees that are more up to date on education and technology. For me I had the opposite experience. I worked at a store that got bought out and the new owner slowly started cutting back all the employees hours that were in high school and hiring only new employees in college. He eventually one by one fired all employees that were in high school for absurd reasons. It was unprofessional and not fair to any of us that worked very hard.

Nian, the Chinese Spring or New Years Day Festival

Nian, the Chinese Spring or New Years Day Festival The Spring Festival is the grandest festival for the Chinese. The Spring Festival is also called Nian, but who knows the term, Nian, was once the name of a furious monster that lived on human beings in the ancient time. How the festival has some relationship with the monster lies in a story about the origin and development of the Spring Festival. The legend says, long ago, there was a monster called Nian. It was born to be very ugly and ferocious, which looked like either dragons or unicorns. On the first and the 15th of each lunar month, the monster would come down from the mountains to hunt people. So people were very much afraid of it and locked their doors early before sunset on the days of its coming. There lived an old wise man in a village. He thought it was the panic in people that made the monster so bold and furious. Thus the old man asked people to organize together and to conquer the monster by means of beating drums and gongs, burning bamboo, and lighting fireworks for the purpose of making large noises to threaten the hateful monster. When he told people about the idea, everybody agreed on it. On a moonless and freezing cold night, the monster, Nian, appeared again. The moment it opened its mouth to people, burst out the frightening noises and fire made by people, and wherever the monster went, it was forced to back off by the terrible noises. The monster couldnt stop running until he fell down with exhaustion. Then people jumped up and killed the evil monster. Savage as the monster was, he lost in the end under the efforts from the cooperation of people. Since then, people have kept the tradition by beating drums and gongs, and lighting fireworks at the coldest day in winter to drive the imagined monsters away and to celebrate the victory over it. Today, Nian refers to the New Years Day or the Spring Festival. People often say Guo Nian, which means live the festival. Furthermore, Nian also means the year. For example, the Chinese often greet each other by saying Xin Nian Hao, which means Happy New Year! Xin means new and Hao means good.

Who Am I Gender As A Social Construct, Not An Inherent Characteristic Essay

Who Am I Gender As A Social Construct, Not An Inherent Characteristic - Essay Example Sex is a physical, genetically based characteristic, visible through the sex organs. Gender is a social construct, created and utilized by society to place people in categories. This is clearly shown through Peter Levin's article "Gendering in the Market: Temporality, Work, and Gender on a National Futures Exchange." In Peter Levin's article, gender is proven to be a social construct and not an inherent aspect of self, and is hierarchically organized within the society." There are few places in America that are more gendered than the Stock exchange and trading floors. Over 90% of all trade floor workers are male, and according to Levin, "are highly heterosexual, hyper-rational, and based on the ideals of domination, aggression, and competition" (Levin 4). Levin creates the model to explain the environment, and how the environment changes to create gender. In an environment that is traditionally thought to emulate one gender or another, such as the trade floor, the discrepancies become clearer. For women to act on the trade floor successfully, they would have to overcome their gender, which, were it a genetic construct, and not a social construct, would be impossible. Yet, when the trade floor is busy, women are considered to be equally successful to men.

Criminal justice Assignment Example | Topics and Well Written Essays - 500 words

Criminal justice - Assignment Example Of course, there is a general societal consensus that certain things are wrong and should be discouraged or criminalized, but for proponents of the Nanny State, the government should seize control of actions and issues where there is no consensus and unilaterally impose its view of morality on these issues. Why is this happening more and more these days? Many experts believe that in an increasingly complex world people are more willing to turn over power to the government in order to make their own lives easier. There is a sense the world can be and should be completely ordered and that government is the right body to do this. This is an unfortunate state of affairs as it tips the important balance between liberty and order far to the side of order. There are so many examples of this way of thinking that it is hard to know where to begin. One of the most shocking examples from recent years is the following headline: â€Å"Chicago Prohibits Foie Gras.† In 2006, Chicago city council voted to ban the delicious appetizer foie gras from the city’s restaurants. Proponents of the ban said the production of foie gras was inhumane. Opponents had a different view. "Government shouldnt be dictating what we eat," said the chef at one French restaurant. The Mayor too was unhappy. "We have children getting killed by gang leaders and dope dealers," he said. "We have real issues here in this city. And were dealing with foie gras? Lets get some priorities."1 These opponents are right. In an era where people expect to be coddled and protected from everything that could possibly harm, they are allowing things as personal as menu choice to be dictated by the government. If an individual does not like to eat foie gras no one will forc e them to eat it; but the Chicago city council went a step further by eliminating this choice completely and limiting the rights of those who do like foie gras. The Nanny State continues to expand, rolling

Tinnitus and Noise-Induced Hearing Loss Essay Example | Topics and Well Written Essays - 250 words

Tinnitus and Noise-Induced Hearing Loss - Essay Example In this discussion tinnitus is defined as: "The perception of a sound that results exclusively from the activity within the nervous system without any corresponding mechanical, vibrating activity with the cochlea." Almost every known hearing problem is in someway associated with tinnitus. For approximately 40 million Americans, it is a permanent condition. It is considered a debilitating condition for around 10 million of those individuals (USACHPPM, 2010). It is important to know that tinnitus does not cause hearing loss. However, the two together can interfere with concentration, focus, and attention span within an individual. Noise-induced hearing loss and tinnitus have even been associated with insomnia and depression (USACHPPM, 2010). So, what is the treatment for noise-induced tinnitus According to USACHPPM (2010), "The short answer is that chronic, noise-induced tinnitus is not treatable, but there are management strategies that attempt to control reactions to the tinnitus."

Irony in Rip Van Winkle

Irony in Rip Van Winkle Washington Irving used so much irony in his short story Rip Van Winkle. The title character is a youthful married Dutch American who has a kind and generous nature. The main character is located in Catskill Mountains of New York way before the American Revolution. Reluctant to profitable labor, the character prefers rambles within the mountains, sitting under the shade gossiping with his buddies moreover, playing with the community children (Irving 105). Washington develops the thesis of the story by use of irony. After meandering with his gun together with Wolf, his close companion, Rip trails himself into the higher parts of the mountains. Soon afterwards, Rip stumbles upon a stranger who was moving what looked like a barrel of liquor. Consequently, with the aid of the Hollands, moreover a whole day of mountain climbing, Rip falls into a solemn, deep slumber. Nevertheless when he wakes up, Rip does not know how long he has been sleeping or where both of his friends have gone off too. He woke up twenty years later, as an aged man and strolls back to his village; he is amazed by the transformations that have occurred. After some commotion, he is joined with his grown-up daughter and her children. The irony is further noticed in Rips coldness to Dame Van Winkle. He was bossed and chided, but he was satisfied. The owner of the bar, Nicholas Vedder dominated the conversations and views of the junto symbolize the colonial governors selected by the Crown. Even as he rarely spoke, his authority was constantly present. This reflects the inactive position the governors accommodated political affairs, as well as the colonists substantial respect for them. (Irving 109) Another irony to reflect on is the ways wherein Irving anticipates lots of of Thoreaus thoughts. Long prior to the retreat to Walden Pond, Washington introduces Rip Van Winkle as a happy mortal, of idiotic, well-oiled characters, who take the humanity easy, eat brown bread or white, any that can be got without difficulty, and would rather go hungry on a penny than labor for a pound which is very ironic. Nathaniel Hawthornes story Young Goodman Brown is saturated, with irony. At the beginning of the narrative a youthful Puritan husband leaves at sunset from his youthful Puritan wife. Faith, like the wife was suitably named, pushes her own appealing head into the street, allowing the wind to play with the pink ribbons which were on her cap, whereas she called to Goodman Brown. Nathaniel Hawthorne says that Faith is appropriately named, an ironic declaration since she later on in the evening, is being acknowledged into the congregation of devil-worshippers as a fresh convert to the evil cluster. The description of faith as pretty as well as her putting on pink ribbons, as a sign of cheerful outlook on life and youthful innocence is also ironic (Hawthorne 405). There is more irony in the Goodman Browns dialogue with the old man. He at first clings to his apparent purity of lineage furthermore claims that his father and grandfather had not deviated from the Puritanical lineage. The old man discovers that not only were his relatives acquainted with the abnormal path but well familiar the devil on an individual level. The irony inside this passage is seen when the devil assists Goodman Browns ancestors during the persecution of Indians and Quakers. There is definitely irony in the fact that it is the majority of the pious church people who emerge at the evil gathering inside the forest. The aged woman who bypasses Young Goodman Brown as well as the devil on the trail is recognized by Brown as the woman who taught her catechism. There is a remarkable irony to this vow because when Goodman Brown came back at dawn; he cannot look at his wife with the identical faith he had before. After Goodman Brown lastly met with the Devil, he asserts that the cause of his lateness was because Faith kept him back awhile. This proclamation has a double implication because his wife actually prevented him from being punctual for his meeting as well as his faith to God expressively delayed his gathering with the devil as well (Hawthorne 409). All through The Cask Of Amontillado, Poe uses dramatic and verbal irony to construct suspense, foreshadow the ending, and moreover add a touch of ghoulish humor. For instance the title cask meaning wine barrel is resulting from the same root statement used to structure casket, which means coffin. Accordingly, the cask symbolically represents Fortunatos casket. Secondly, Fortunatos name which is Italian implies good fortune, luck. Nevertheless, Fortunato is so unfortunate because he was heading to his death. Another element of irony is Fortunatos Costume. He dresses as a court clown. His celebratory outfit contrasts with the terrible fate that awaits him. Moreover, occasionally, the bell on top of his cone-shaped hat tinkles a nice comic feeling from Poe. Another aspect of irony is when Fortunato asks Montresor if he is a mason, signifying a member of the fraternal array of Freemasonry. It is ironic that Montresor says he is certainly a mason. Nevertheless, he is using the expression to mean a craftsman who constructs buildings using (Cecil 41). Poe also uses irony repeatedly in the dialogue. For instance, when Montresor meets Fortunato, he tells him that he is lucky they met. Later on, when Montresor pretends to be worried about Fortunatos scything cough as they go down into the tombs, he tells him that they have to go back because his health is precious. Fortunato tells him not to worry because the cough will not kill him. Montresor quickly agrees that the cough will not kill him; the audience can nearly see a devilish gleam within Montresors eyes, because he surely knew that Fortunato will die. He later opens a bottle of wine furthermore toasts Fortunato to his long life.
