Summary Of The Yellow Wallpaper By Charlotte Perkins...
Am I Hysterical for Writing This? If we all saw through the eyes of women, would we see the world a different way? Would we all be considered hysterical? Or would we just all be ââ¬Å"normalâ⬠? In the short story The Yellow Wallpaper by Charlotte Perkins-Gilman and the novel The Key by Junichiro Tanizaki we see the metamorphosis of two women under two very different scenarios. The unnamed woman in The Yellow Wallpaper is stuck in a room where she transforms into a completely different soul. In The Key, the wife, Ikuko appears to also transition throughout the novel, but in the end we are left questioning whether she truly changed or if we, the readers, were just lied to and her true character really came out. Both stories begin with the women acting in a way that is ââ¬Å"acceptableâ⬠by their husbands, but throughout the novel we see them blossom from submissive wives into their inner, independent, selves. In this imagination challenge I will focus on what happened durin g the in between, the metamorphosis period, and consider their mindsets and the outside pressures they faced that made them into the feminists that they both are at the end of their stories. Feminism means all different things according to different people. Scholar Sylvia Walby mentions in her book that the term ââ¬Ëfeministââ¬â¢ has become ââ¬Å"contentiousâ⬠and ââ¬Å"stigmatizedâ⬠, but ââ¬Å"an alternative approach to the definition of feminism is to consider people and projects that pursue the goal of reducing gender inequality to be

Forensic in Pop Culture The CSI Effect Essay - 1935 Words
Introduction. With producing reality shows comes producing inaccuracies in portrayals in order to reach as many viewers and gain as high ratings as possible every week with each new episode. Every day life is boring, yet people tend to be attracted to the relatable shows that portray real life in eccentric ways ââ¬â ways that they believe could be imitated by the average person. In many cases, these shows could remain harmless, as it is entertainment. No matter how crude or erroneous, it is just television. However, what happens when these sources of amusement actually start being damaging? Research has shown that crime shows like the ever popular CSI: Crime Scene Investigation have started becoming significantly detrimental to criminalâ⬠¦show more contentâ⬠¦There is even an interactive exhibit known as ââ¬Å"CSI: The Experienceâ⬠in Orlando, Florida where people can pay to try out their investigative skills in crime scenes and laboratories similar to ones that real forensic specialists use. If you search through your television guide, you will see at least three of these shows on at the same time on different channels, many even having all-day marathons for you to enjoy on Saturday morning. Simon Cole and Rachel Dioso-Villa have analyzed that many of these fictitious programs attempt to make science ââ¬Å"sexy,â⬠which may be the reason why we are so attracted to them. The scientists look stylish at all times; wearing nice suits or dresses out on the field or in the laboratory, having normal work days, finding everything they need, having all of the state-of-the-art equipment and staff they need, and more importantly, they get everything done quickly and effectively. This glamorous, action-packed lifestyle gives a false sense of what the career itself actually entails, which includes giant lab coats, numerous court sessions, understaffed laboratories, no gun, and an abundance of paperwork.

Reading Autobiography Free Essays
Although I do not have many vivid memories of my childhood the few things I do recall from my early years mostly seem to focus around school and my academics and interactions with children my own age. It is nearly impossible to pinpoint when exactly it was that I began to read but it must have been somewhere around the end of kindergarten and the beginning of first grade. I didnââ¬â¢t attend preschool so up until kindergarten my primary interaction with others was in my first language, Spanish. We will write a custom essay sample on Reading Autobiography or any similar topic only for you Order Now I can recall learning the alphabet and the sounds of all letters and I started to make out certain words like ââ¬Ëseeââ¬â¢ and ââ¬Ëmyââ¬â¢. The most influential person in the process of acquiring the skills I needed to read must have been an instructional assistant, Mr. Torres who would help me and other bilingual students regularly in the classroom. Of course the instruction by my teacher set the basis for my learning but the one on one help that he provided helped me make connections to my learning in Spanish and that made me feel very comfortable. The first books I began to read must have been simple stories that I came to memorize. Stories like The Gingerbread Man or Brown Bear that had repetitive lines were probably how I started to make connections with words, sounds and pronunciation of those words and sounds. Learning to read made me feel empowered and I remember wanting to read ââ¬Å"big kidsâ⬠books once I felt I was capable. Among my favorite types of books were scary chapter books like the series of Goosebumps as well as biographies of famous athletes. Among my least favorite must have been nonfiction and folktale because they never really managed to pull me in and I was always very skeptical about such fantasy. Unfortunately, this thrive to read did not last very long because I started to drift away from the constant practice of reading around the fifth grade and started seeing it more as an obligation rather than a choice. As a whole the literacy environment in my household was actually a very positive one and ever since I can recall my mom has always been a big reader and has many books and magazines throughout the house. All of her reading though was done in Spanish when I was growing up because as I was learning how to read my mom was learning the English language. My dad on the other hand has never been a big reader. Actually I canââ¬â¢t recall a time when I have seen him sit down and read something simply for leisure. I also had an older sister who was just a grade ahead of me in school and she has always been a bit of a bookworm and was constantly going through different books as we grew up. Even with all these things I think the language barrier influenced my detachment from reading. In my household we rarely spoke English, maybe if my mom and dad knew the language or were more comfortable with it they might have pushed me to read more or took the time to sit down and read to me. Come to think of it my mom would read to me but she would do it in Spanish and it was a bit boring for me. She would read common stories that I had already heard like the three little pigs or something of that sort and all I would gain out of this was amusement because the way things translated to me was funny. My mom did take us to the city Library and I remember going to story time or to some sort of show based on books. I remember seeing a magician and also petting a snake. As for having materials to read and write, there was always plenty throughout my house. My mom kept a full stock of pencil and paper as well as of books it was just a matter of me doing the actual work. She constantly asked me to explain to her what I was reading or writing for school but I always seemed to find a way to not spend too much time with it because all I wanted to do was play with the neighborhood kids or run off to soccer practice. In school the literacy environment was very positive as well and I remember how much time and dedication the faculty would place on reading and the development of reading skills. I canââ¬â¢t remember who formally taught me how to read but it must have been either Mrs. Diamond or Miss Falgot my first and second grade teachers, because by third grade I remember being able to read fluently. They used several different types of methods but I remember being read to very often by Miss Falgot. I do recall being placed in groups and having partners whom you read to and vice versa. I believe both Mrs. Diamond and Miss Falgot were key role players in my acquisition of reading skills and although I donââ¬â¢t recall specifics they did their job because by third grade I was at the top of my class. I do remember a particular case that had a bit of a negative effect on me in terms of reading. I remember being in either fourth or fifth grade reading as a class and the teacher called on me to read a paragraph. I donââ¬â¢t remember what I was thinking but I was not listening and wasnââ¬â¢t even on the right page, once I located it I got nervous and couldnââ¬â¢t even read. Luckily the teacher called on someone else but I felt horrible. As a class throughout elementary I remember visiting the library and running to the sport books section. The Library was so calm and always cool and I remembering going in there on hot summer days to get away and read a good book. The librarian I remember was always very sweet and she was very patient with all the students. As for literacy events the only thing that is clear in my mind is the book fairs that occurred maybe twice or three times a year. They were very fun and I remember they made even the boring books seem interesting. They set up all kinds of posters and it was something that I always looked forward to. As an adult I began to pick up old habits especially after I came into college. I canââ¬â¢t say I read a lot but I do find time to fit in a book every once in a while. I am still a big fan of autobiographies and I have recently developed a liking for books in Spanish. I usually read on the weekends when I am well rested and have slept in. I also like to go to parks and sit in the shade and enjoy a good book or story or even an interesting article. I think reading is very important and not only to help us expand our vocabulary or help us academically but when you read a good book you get a chance to escape your everyday and it gives you an insight into a story or a character in the way a TV or radio cannot. It captivates you and manages to get all of your attention but at the same time relaxes you. I think reading is something that should be taught to students but not just in order to help them academically but educators should also focus on showing the importance of literature in our lives and the positive way it influences our lives down the road something the media of today cannot manage to do. Writing equally should be not only taught for the purpose of education but in a way those students value it and continue to practice it even without a teacher pushing them to do so.

Black-Scholes Option Pricing Model free essay sample
The derivative asset we will be most interested in is a European call option. A call option gives the holder of the option the right to buy the underlying asset by a certain date for a certain price, but a put option gives the holder the right to sell the underlying asset by a certain date for a certain price. The date in the contract is known as the expiration date or maturity date; the price in the contract is known as the exercise price or strike price. The market price of the underlying asset on the valuation date is spot price or stock price. Intrinsic value is the difference between the current stock market price and the exercise price or simply higher of zero. American options can be exercised at any time up to the expiration date. European options can be exercised only on the expiration date itself. (Hull, 2012). For example, consider a July European call option contract on XYZ with strike price . When the contract expires in July, if the price of XYZ stock is $75 the owner will exercise the option and realize a profit of $5. He will buy the stock for $70 from the seller of the option and immediately sell the stock for $75. On the other hand, if a share of XYZ is worth $67 the owner of the option will not exercise the option and it will expire worthless. In this case, the buyer would lose the purchase price of the option. One of the best-known and most widely used formulas in finance is the Black-Scholes option pricing model. It was originally developed in 1973 by two professors, Fischer Black and Myron Scholes. They designed the model to calculate the price of a European-style call option on non-dividend-paying stocks. Black-Scholes option pricing model assumes that the stock pays no dividends during the optionââ¬â¢s life, European exercise terms are used, markets are efficient, no commissions are charged, interest rates remain constant and known and returns are log-normally distributed (Black and Scholes, 1973). Black-Scholes gave the formula to estimate the value of a call option: C = Ps N(d1) X e-rT N(d2) where C = price of the call option Ps = spot price X = exercise price r = risk-free interest rate T = current time until expiration ? = volatility of share price N() = area under the normal curve d1 = [ ln(Ps/X) + r T ] / ? vT d2 = d1 ? vT Call Option Pricing Example XYZ is trading for $75. Historically, the volatility is 20% (? ). A call is available with an exercise of $70, an expiry of 6 months, and the risk free rate is 4%. ln(75/70) + (. 04 + (. 2)2/2)(6/12) d1 = = . 70, N(d1) = . 7580 . 2 * (6/12)1/2 d2 = . 70 [ . 2 * (6/12)1/2 ] = . 56, N(d2) = . 7123 C = $75 (. 7580) 70 e -. 04(6/12) (. 7123) = $7. 98 Intrinsic Value = $5, Time Value = $2. 98 Black-Scholes modelââ¬â¢s inputs: There are five main Black-Scholes Model inputs affect to options price. The inputs include the spot price, the exercise price, time to expiration, the interest rate, and the volatility of the stock. The intrinsic value of the stock is affected by the stock price increase or decrease. This determines if the stock option is valuable or not. For evaluate the influence of five factors in to the optionââ¬â¢s price on stock, we calculated the optionââ¬â¢s price using Numa Option Calculator on the Call Option Pricing Example to increase each input by 10% and discussed below: Determinants of the Call Premium: Inputs |Inputs (^10%) |C (call price) |Change | |Ps |$82. 5 |$14. 3 |^ | |X |$77. 0 |$ 4. 0 |v | |T |6. 6 months |$ 8. 3 |^ | |r |4. 4% |$ 8. 1 |^ | |? |22% |$ 8. 3 |^ | Spot Price: The option price depends on the market price of the underlying asset. If the price of the underlying asset increases, the premium of a call option will rise and the premium of a put option will fall. If the price of the underlying asset drops, the premium of a put option will rise and the premium of a call option will fall. Exercise Price: This is the price level at which the option holder has the right to buy or sell the underlying asset. The price of an option is naturally related to the exercise price. When exercise price increases, spot price also increases and moving for the option to go in-the-money, call options become less valuable. Time to Expiration: The time (in years) until the option expires and the holder is no longer entitled to exercise the option. The longer day the option have, the more exercise opportunity and the more profit optionââ¬â¢s holders can enhance. Both call and put options become more valuable with the increase of the duration until the expiration, because the larger the interval of time the greater chances has the holder to exercise the option in a favorable way. Risk free Interest Rate: The risk free interest rate for the period until the option expires. The interest rate affects the option price according to the type of the option, through the means of the time value of the money. The increase of the interest rate determines the decrease of the present value of the exercise price and, as a consequence, the value of the call option increases and the value of the put option decreases. In practice, if the interest rate increases, the price of the call option increases because the underlying assets price is lower, the difference being invested at the interest rate without risk. For the put option, the increase of the interest rate determines the decrease of the options price because the purchase of the derived asset postpones the cashing of the assets price until the option is exercised, and the increase of the interest rate represents an opportunity loss (Craiova and Ispas). Volatility: Volatility, which is an unpredictable factor that is very difficult to be measured. Volatility expresses the expectations to fluctuations in the price of the underlying asset. The volatility has an influence on the value of an option because it is one of the factors that determine the probability to what extent the option will end in the money, and thus the size of payoff at expiry; The higher the volatility, the higher the value of the option price. The option price will therefore rise if the volatility of the underlying assetââ¬â¢s market price increases. The option pricing model also used to determine another useful number besides the option price. The variable N(d1) is called the hedge ratio, or the delta, for the call option. The hedge ratio tells how much the option price will change when the underlying stock price changes by some small amount. For example, our option for XYZ had a hedge ratio of about . 76. This means that if the price of XYZ increased (or decreased) by one dollar per share, the price of the call option would increase (or decrease) by about $0. 76. This information is very useful for option traders who are trying to combine stocks and options into portfolios that will have offsetting movements. The number of call contracts or stocks held can be adjusted using the hedge ratio to produce protected portfolios. The hedge ratio will change whenever the stock price changes and also as the time to maturity decreases. Thus, the information provided by the hedge ratio is good for only small stock price changes, and for only a short period of time. REFERENCES Black, F. and Scholes, M.
