The Value of Sex in Romeo and Juliet and Measure for Measure Essay

  Ã‚  Ã‚  Ã‚   Renaissance England often treats female sex and virginity as a commodity. Shakespeare recognizes this belief system in Measure for Measure and Romeo and Juliet. In Romeo and Juliet, Juliet's virginity acts as a commodity. However, it is not her commodity; rather, it belongs to her father. Capulet uses it as a bartering tool. In act three, scene four, he makes a marriage agreement with Paris. He says, "Sir Paris, I will make a desperate tender / Of my child's love. I think she will be ruled / In all respects by me. Nay, more, I doubt it not" (12-14). The first definition in the Oxford English Dictionary defines tender as "to offer or advance (a plea, issue, averment; evidence, etc.) in due and formal terms; spec. to offer (money, etc.) in discharge of debt or liability" (def. 1). The OED cites Littleton's Tenures in 1544 as an example of this definition: "The Lorde maye tender a conuenient mariage wythout deperagyng of such an heir female." Subsequent definitions also define tender as "to make (physically) tender, soft, or weak" (def. 2d). These definitions prove the ecconomic value of Juliet's body. Capulet weakens Juliet physica lly in 3.5 by ordering her to marry Paris or "beg, starve, die in the streets" (192). In many productions, Capulet strikes Juliet, emphasizing her "tender" state. He has full control over Juliet's life and consequently, her body. Her virginity is a bartering tool, something he can sell on a whim to the highest bidder. Within this system of arranged marriages, sex functions as a commodity.    Measure for Measure also speaks to the commodification of sex by highlighting female virginity, those who are and those who aren't. In this play, female virginity functions as a... ...odity, desperately sought after by men. Their commodity places them in a double bind: "To be sexually active is to be suspect, to be a virgin is to be desirable and therefore potentially sexually active and potentially suspect. Either way women lose. Either way they are sexualised" (Macfarlane 78).       Works Cited:    Carlson, Susan. "'Fond Fathers' and Sweet Sisters: Alternative Sexualities in Measure for Measure."

Poem of William Caslos William Essay

William Carlos Williams is a pioneer who creates a whole new realm in American poetry. He is regarded as an important and influential poet because of his unique and usually plain style. The poem â€Å"Poem† is one of the most prominent poems reflecting Williams’ style of writing. In this piece of work, Williams discusses a central contrast between the mortality of life and immortality of art through the image of two roses – in nature and in poetry. It can be said that life is symbolized by the rose, the central image and also the main theme of â€Å"Poem†. The real rose and unreal one are skillfully used to represent two factors: the reality and the art. In nature, a rose which cannot avoid the cycle of time undergoes stages of nature rules. First, it germinates from a seed. Then, it grows up and blooms or blossoms. Next, it fades or discolored. Finally, it dies. â€Å"The rose fades – And is renewed again – By its seed naturally† (Williams, 1983). The issue of the rose fading show that life, no matter what forms, follows the nature changing rule and eventually fades away. Meanwhile, Williams uses the image of the rose in poem to respect the art because the real rose will fade naturally but the rose of art keeps an ever-lasting beauty: â€Å"Save in the poem – shall it go – to suffer no diminution – of its splendor† (Williams, 1983). Generally, the whole poem presents the central contrast of nature versus art, death versus life and cycle of time versus perfection that lasts forever. With respect to the highlighted image of the rose in poetry, it can not be touch but lives forever and remains perfect, fresh, young, and beautiful regardless of time. It has the empowerment of splendor, perfection, and immortality. In fact, Williams’ intention after his words of praising the power of the rose in poem is to advocate the power of art in general. It seems that the poet gives prominence to art whose role is to inspire and guide people through curves of life thanks to its beauty and significance of teaching truth, giving beauty and pleasure, shaping moral characters, showing power of language and showing human experience.

Reasons Why Projects Fail - 710 Words

Reasons Why Projects Fail By Tom Carlos PMP In a perfect world, every project would be on time and within budget. But reality (especially the proven statistics) tells a very different story. It s not uncommon for projects to fail. Even if the budget and schedule are met, one must ask did the project deliver the results and quality we expected? True project success must be evaluated on all three components. Otherwise, a project could be considered a failure.

Consumer Decision Making Supply And Demand - 3065 Words

Consumer Decision Making: Supply and Demand Demand in the wireless industry is determined by the aggregation of individual mobile carriers through the number of wireless subscriptions. Economists all agree that price for a service is an important factor in the decision making for consumers, however it is definitely not the only factor and may not always result in the deciding outcome. Based on pricing, microeconomics can estimate and forecast with plausible accuracy what a consumer may pay for and how much of that service will be purchased.

A new entrant like Wind Mobile may not be profitable given the data due to the decreasing rate of new subscriber growth i.e. lack of main revenue source via selling handset as well as monthly stream of revenue from services. In order for Wind Mobile to be sustainable in the long run, it needs to make a profit where its price is greater than its average cost (including fixed capital infrastructure as well as user’s variable mobility cost.) The population in Canada provided by Statistics Canada demonstrates a healthy positive linear growth over the period of 2005 and 2012. After doing statistical analysis, I can conclude my finding that as population increase; the demand for wireless subscribers also increases while at a very slow rate. Furthermore, my regression findings can help forecast the demand for wireless subscribers over time based on an estimate of population for a given year. In order to do so, we must first estimate the population for a given year based on this equation: Population (in millions) = - 676.5029 + 0.3535 * Year After, we substitute our estimated population value for a given year into another equation to determine the number of wireless subscribers: Wireless Subscribers (in millions) = - 131.5938 + 4.6155 * Population (in millions) The demand curve for Wind Mobile

Capital Punishment Essay Its Fair and Effective - 964 Words

Capital Punishment - Its Fair and Effective Confronting head-on two of the most prominent objections to the death penalty is the object of this paper: Is the death penalty a miscarriage of justice? And Does it Deter Crime? Its a miscarraige of justice. In a survey Professors Hugo Adam Bedau and Michael Radelet found that 7000 persons were executed in the United States between 1900 and 1985 and that 35 were innocent of capital crimes (1). Among the innocents they list Sacco and Vanzetti as well as Ethel and Julius Rosenberg. Although their data may be questionable, I do not doubt that, over a long enough period, miscarriages of justice will occur even in capital cases. Despite precautions, nearly all human†¦show more content†¦I would favor retention of the death penalty as retribution even if it were shown that the threat of execution could not deter prospective murderers not already deterred by the threat of imprisonment (5). Still, I believe the death penalty, because of its finality, is more feared than imprisonment, and deters some prospective murderers not deterred by the thought of imprisonment. Sparing the lives of even a few prospective victims by deterring their murderers is more important than preserving the lives of convicted murderers because o the possibility, or even the probability, tht executing them would not deter others. Whereas the live of the victims who might be saved are valuable, that of the murderer has only negative value, because of his crime. Surely the criminal law is meant to protect the lives of potential victims in preference to those of actual murderers. Murder rates are determined by many factors; neither the severity nor the probability of the threatened sanction is always decisive. However, for the long run, I share the view of Sir James Fitzjames Stephen: Some men, probably, abstain from murder because they fear that if they committed murder they would be hanged. Hundreds of thousands abstain from it because they regard it with horror. One great reason why they regard it with horror is that murderers are hanged (6) Penal sanctions are useful in the long run for the formation of theShow MoreRelatedPersuasive Essay for Pro Capital Punishment1283 Words   |  6 PagesPersuasive Essay Why Capital Punishment Should Remain in Effect Stefanie Ridgway DeVry University, ENGL 112 Professor Adams April 19, 2010 Capital punishment, otherwise known as the death penalty, has been effective tool in our country’s justice system since its inception.

Children and Adolescents with New-Onset Epilepsy Free Essays

Children and adolescents with new-onset epilepsy Journal Article Epilepsy is one of the most common neurologic disorders in childhood, with a widespread rate of approximately 3-4 per 1,000. In the paper they explore parent’s perceptions of their child’s quality of life and the impact of the diagnosis on their family. It’s talking about how the parent’s and children’s lives get accustomed to everyday normal functioning activities. We will write a custom essay sample on Children and Adolescents with New-Onset Epilepsy or any similar topic only for you Order Now Whenever there is any emotional well-being, self-esteem, and physical changes with their condition due to the epilepsy. Data was collected as part of the Stand and New Antiepileptic drugs (SANAD) trial. SANAD compared clinical trial and cost-effectiveness of standard and new AEDs. SANAD recruited 2,437 patients (1,983 age older than 16 years; 454 children age between 5 and 16 years), with history of two or more definite unprovoked seizures in the previous year. Talks about the primary outcomes were time to treatment failure, and time to 12-month remission. Children from 8-15 years were asked to answer self-complete questionnaires annually and thereafter for 4 years for SANAD. The parents gave written consent to long-term follow-up. Parents were asked to complete questionnaires to assess their child’s quality of life. It talks about parents being affected by their child’s seizures at home or at family outings. How it can take a toll on everyday things they do. I agree that children with epilepsy (CWE) are more likely to have learning disabilities and to experience academic underachievement. Well I agree because it’s already hard for children to fit in at school and to try to focus is even harder. I agree with the finding that adolescence is a critical period for identity formation and peer group identification. Being an outcast from their peers is an important concern for adolescents. I agree because the adolescents can experience self-conscious, ashamed of their epilepsy, and secretive behavior. I agree with the finding that single parents have less support from other networks, may cause them to be more concerned about their child’s well-being. I agree because their only support is usually themselves, thereafter, it’s not easy raising and caring for a sick child. I agree with the argument that it is a seizure event, not a diagnosis of epilepsy that impacts on daily functioning. Because an epileptic attack is more traumatizing and over whelming for a child, then being told you have epilepsy. Which some adolescents don’t know what this means for them. Those who scored 13 are considered to be psychiatric morbidity. Children with new-onset epilepsy had significantly poorer for physical, emotional and friend’s domains. A recent study found children in the United Kingdom reported low levels of child well-being, despite relatively high levels of wealth, compared to children from other European countries. What I found interesting was that CWE should be assessed for psychosocial problems in the beginning so intervention can be done in time for no further damage with the child. Interventions aim to increase self-esteem. I believe these studies are great resources for the families of the epileptic children. It gives them more insight in their everyday functions in life. Without these kind of studies parents might be clueless to what could be happening to their child in school or even at home. It hard for the families of these adolescents to undergo these kinds of trials, but with all the information and support groups out there it can be very helpful for everyone. In conclusion I believe with more moral support and patience, much can be done for children with these special conditions.

Determining the limiting reactant and the percent yield i a precipitation reaction free essay sample

One example of a double replacement (metathesis) reaction is the mixing of two solutions resulting in the formation of a precipitate. In solution chemistry, the term precipitate is used to describe a solid that forms when a positive ion (cation) and a negative ion (anion) are strongly attracted to one another. In this experiment, a precipitation reaction will be studied. Stoichiometry will then be used to investigate the amounts of reactants and products that are involved. The word stoichiometry is derived from two Greek words: stoicheion (meaning â€Å"element†) and metron (meaning â€Å"measure†). Stoichiometry is an important field of chemistry that uses calculations to determine the quantities (masses, volumes) of reactants and products involved in chemical reactions. It is a very mathematical part of chemistry. In this experiment, you will react a known amount of sodium carbonate solution with a known amount of calcium chloride solution. The skeletal (unbalanced) equation for the resulting double replacement reaction is: Na2CO3(aq) + CaCl2(aq) ? NaCl(aq) + CaCO3(s) Note that three of the chemicals have their states or phases designated as (aq) and one is designated as (s). The (aq) represents the term aqueous which means that the substance is soluble and dissolved in water. The (s) means that the substance is a solid (in this case, it is a precipitate). Precipitate formation is easily observed as the mixed solutions turn cloudy and, if desired, the precipitate can be easily separated from the solution by filtering. Since your precipitate will be separated and weighed, you will need to dry the precipitate in a drying oven before measuring its mass. Stoichiometry will then be used to determine the amount of precipitate that should be formed in the reaction. It is often difficult as well as impractical to combine just the right amount of each reactant that is required for a particular reactant that is required for a particular reaction to occur. Given this fact, this experiment is designed so that only one of the reactants will be completely used up. This is called the limiting reactant because it limits the amount of products formed. Since the other reactant will have a quantity remaining, it is called the excess reactant. One of your tasks will be to determine which of your reactants is limiting and which is in excess. The two chemical reactants in this experiment have common uses in our lives. In one solid form, sodium carbonate is known as â€Å"washing soda† and is used to enhance the effectiveness of laundry soap. Calcium chloride solid can act as a desiccant (drying agent) and is used by recreational vehicle owners to remove moisture from the air in the vehicle during winter storage. OBJECTIVES 1. to observe the reaction between solutions of sodium carbonate and calcium chloride. 2. to determine which of the reactants is the limiting reactant and which is the excess reactant. To determine the theoretical mass of precipitate that should form. 4. to compare the actual mass with the theoretical mass of precipitate and calculate the percent yield. MATERIALS Equipment Chemicals Balance 0. 70 M sodiuim carbonate solution, Na2CO3 2 graduated cylinders – 25 mL 0. 50 M calcium chloride solution, CaCl2 3 beakers – 250 mL dH2O wash bottle Filtering apparatus (ring with stand, funnel) Filter paper Drying oven Lab apron Goggles PROCEDURE 1. Put on your lab apron and safety goggles. 2. Obtain two clean, dry 25 mL graduated cylinders and two clean, dry 250 mL beakers. In one of the graduated cylinders measure 25 mL of the Na2CO3 solution. In the other graduated cylinder measure 25 mL of the CaCl2 solution. Record these volumes in your lab notebook. 4. Pour the contents of both graduated cylinders into one of the 250 mL beakers and observe the results. Record these qualitative observations in your notebook. Allow the contents of the beaker to sit undisturbed for 5 min. to see what happens to the suspended solid particles. Meanwhile, proceed to step 5. 5. Obtain a piece of filter paper and put your name on it using a pencil. Weigh and record the mass of the filter paper, then use it to set up a filtering apparatus as shown in Figure 6D-1. 6. Use the wash bottle to lightly wet the filter paper in the funnel to keep the filter paper in place. Swirl the beaker and its contents to suspend the precipitate in the solution, then pour it carefully and slowly into the filter funnel. It takes time to complete the filtering process so plan to do it in stages. Use the wash bottle to rinse the remaining precipitate from the beaker. 7. Use the wash bottle one last time to rinse the precipitate in the filter paper. This will remove any residual NaCl(aq) that remains with the precipitate. 8. After the filtering is complete, remove the wet filter paper containing CaCO3 precipitate and suspend it carefully in the third 250 mL beaker. Put your labeled beaker with filter paper + precipitate in the drying oven for 30-45 min. 9. Remove the beaker with filter paper + precipitate from the drying oven and allow to cool for a few minutes. 10. Weigh and record the mass of the dry filter paper containing the CaCO3 precipitate. 11. Clean up all your apparatus. 12. Wash your hands thoroughly with soap and water before leaving the laboratory. Reagent Disposal Rinse all solutions down the sink with copious amounts of water. Any solids should go into the designated containers. Post Lab Considerations The double replacement reaction in this experiment formed two chemicals which are commonly known to you. The NaCl(aq) is salt water and the CaCO3(s) is a component of some classroom chalks. Using the data collected, you will be able to calculate the moles of each of the chemicals that are added together to react. Then using the principles of stoichiometry you will be able to determine which chemical is the limiting reactant and thereby predict how much precipitate should form. This stoichiometric determination will then be compared to the actual mass of CaCO3(s) formed. Chemists are often concerned with optimal yields in manufacturing a certain chemical. One way of measuring this is to calculate the percent yield of that particular chemical by using this formula: Percent yield = actual mass produced (grams)____ x 100% theoretical mass produced (grams) Include the following information in the results section and data tables: Qualitative observations Quantitative observations Volume of 0. 70 M Na2CO3 solution Volume of 0. 50 M CaCl2 solution Mass of filter paper + dry solid CaCO3 Mass of filter paper ANALYSIS OF RESULTS 1. Copy the chemical equation for the reaction from the introduction and balance it. 2. From your Part I results, calculate the moles of Na2CO3 that were added to the beaker. 3. From your Part I results, calculate the moles of CaCl2 that were added to the beaker. Use your answers from Analysis 1-3 above and stoichiometric principles to determine which chemical is the limiting reactant. 5. Use stoichiometric calculations to determine the theoretical mass of CaCO3 precipitate that should have formed. 6. From your Part II results, calculate the actual mass of CaCO3(s) precipitate that formed. 7. Calculate the percent yield of CaCO3(s). FOLLOW-UP QUESTIONS 1. If you were to evaporate the filtered solution to dryness, would you be left with only solid NaCl? Explain. 2. What theoretical volume of the Na2CO3 solution used in this experiment would result in no excess reactant? 3. A precipitation reaction occurs when 50. 0 mL of 0. 50 M BaCl2(aq) is mixed with 75. 0 mL of 0. 75 M Na2CO3(aq). The only precipitate is the BaCO3(s) formed. a) Write the balanced equation that describes this reaction. b) Which chemical is the limiting reactant? c) Predict the theoretical mass of BaCO3(s) that should form. d) This experiment was conducted and the percent yield was found to be 82%. What was the actual mass of BaCO3(s) that formed?
