Elizabeth Wurtzel Has Died at 52

Elizabeth Wurtzel Has Died at 52 The bestselling confessional memoirist Elizabeth Wurtzel died Tuesday from complications following metastatic breast cancer. She was 52. Her husband, Jim Freed, told the Washington Post that the cause of death was “complications from leptomeningeal disease, which occurs when cancer spreads to the cerebrospinal fluid.” In 2015, she wrote about her cancer diagnosis for Vice: “So I have breast cancer, which like many things that happen to women is mostly a pain in the ass.” She had a double mastectomy with reconstruction and became an advocate for BRCA testing, which would have shown her that she had the breast cancer gene before her official diagnosis. In her 1994 memoir, Prozac Nation, published when she was just 26, she candidly shares her struggles with depression and addiction while she galavants through her education Harvard. At the time, the book stood apartâ€"there weren’t many others openly discussing the vast darkness of mental illness beyond Darkness Visible by William Styron (1990) and Girl, Interrupted by Susanna Kaysen (1993). Her work inspired many more confessional memoirs by young peopleâ€"a genre that is still booming two decades later. After  Prozac Nation came Bitch, a feminist essay collection about “difficult women,” from powerful Biblical women to Yoko Ono, Hillary Rodham Clinton, and Sylvia Plath. Then she published another deeply personal memoir, More, Now, Again, about her descent into drug addiction. In 2014, she wrote her final book, Creatocracy, a deep dive into the United States Constitution, the Intellectual Property Clause, and Hollywood. Her work landed on nearly every list of books about mental illness weve compiled. Her candor, humor, and willingness to share the deepest, darkest of her days has changed the literary landscape.

Milton s Paradise Lost Is God A Tyrant - 1818 Words

In Milton’s Paradise Lost, surely we have come to ponder upon the makeup of Satan’s attractable character—his rebellious, seductive, almost â€Å"bad-ass† attitude—a case of admirable evil. But let us not forget his ambition, his strive to weld the image of God. We have seen many moments throughout where we get Satan’s ground for imitating the image of God: â€Å"†¦In imitation of that Mount whereon / Messiah was declar’d†¦Ã¢â‚¬  (V 764-65). But why does Satan do this? What is it in Satan that causes him to â€Å"look up† to God? Is God a tyrant yet a role model to Satan? I propose that Satan’s drive is something more than just an act of pretending; maybe, it is rather a means of trying to grasp what he has been taken away from him. Or, we can say that Satan was more. Perhaps he came to existence not in the mold of angel, but as a divine tool. There must be a reason as to: why Satan was considered God’ s â€Å"first and favorite angel†? This seems to suggest that Satan is, originally, at some level of divinity; an experiment of God’s that was put to the test (or is a test)—a divine prototype. First, to prove that Satan must be something more than a mere â€Å"favored† angel, some kind of divine being, let us consider Adam’s longing for a companion (as I think the concept here holds basis): he reasons with God as to why it is appropriate for him to have an equality alongside, and of course, God, â€Å"not displeased,† grants Adam’s request, that is to become, Eve. Now imagine God in the shoes of Adam, that isShow MoreRelatedThe Role of Satan in Paradise Lost1455 Words   |  6 PagesThe Role of Satan in â€Å"Paradise Lost† John Miltons epic â€Å"Paradise Lost† is one that has brought about much debate since its writing. This epic tells the Biblical story of Adam and Eve, although from a different perspective than what most people usually see.

Milton, a writer devoted to theology and the appraisal of God, may not have intended for his portrayal of Satan to be marked as heroic. Yet, this argument is valid and shares just how remarkable the study of literature can be. Milton wrote his tale of the fall of man in the 1674.

Essay on The Great Barrier Reef - 1258 Words

The Great Barrier Reef is one of the wonders of the natural world. It was declared a World Heritage area in 1981 and added to the National Heritage List in 2007. Unfortunately, the Great Barrier Reef faces many threats. Pollution caused by direct or indirect human activities are major threats to Australian reefs. (source 1). Two million tourists visit the coral reef every year. This is great for the economy; however it can have huge negative impacts on the coral reef. The tourists are carried around the Great Barrier Reef Marine Park (GBRMP) by over 500 commercial vessels which drop fuel, anchors and other forms of pollution that damage the reef. The tourists also break the fragile corals by touching and reef walking as well as†¦show more content†¦Overexploitation of fish, the use of fishing nets, poison fishing, dynamite fishing and coral harvesting are other threats to the Great Barrier Reef. (Source 1) According to source 6, the Great Barrier Reef is extremely vulnerable to climate change. For example, an increase in carbon dioxide concentration from 380 ppm to 450 ppm in the atmosphere will increase the sea temperature by one degree which is enough to cause severe coral bleaching. On top of that the sea water will become more acidic and the sea levels will rise, posing more threats to the reef. Adding to the threats is the crown-of-thorns starfish which was introduced by sailors emptying ballast water into the coral reef. The crown-of-thorns starfish has been destroying coral since 1960. (source 3) As corals die, many animals and plants are losing their habitats causing a drop in the biodiversity of species and population levels. (source 4) Cyclones and storms are natural events that also have devastating impacts on coral reefs. An example of this is Cyclone Ingrid in 2005 which ripped through about 10% of the Great Barrier Reef lifting many tonnes worth of coral two or three meters in diameter around ‘like marbles’. This caused avalanches of sediment and coral skeletons which smothered everything underneath. Coral reefs take between two to twenty years to recover after storms such as these.

Effects of Teenage Smoking Free Essays

The Effects of Smoking on Adolescent Behavior and Their Ability to Perform Well in School James Grimes Eastern Kentucky University Abstract There is a considerable body of empirical research that has identified adolescent peer relationships as a primary factor involved in adolescent cigarette smoking. Despite this large research base, many questions remain unanswered about the mechanisms by which peers affect youths’ smoking behavior. Understanding these processes of influence is the key to the development of prevention and intervention programs designed to address adolescent smoking as a significant public health concern. We will write a custom essay sample on Effects of Teenage Smoking or any similar topic only for you Order Now In this paper, theoretical frameworks and empirical findings are reviewed critically which inform the current state of knowledge regarding peer influences on teenage smoking. Specifically, social learning theory, primary socialization theory, social identity theory and social network theory are discussed. Empirical findings regarding peer influence and selection, as well as multiple reference points in adolescent friendships, including best friendships, romantic relationships, peer groups and social crowds, are also reviewed. Review of this work reveals the contribution that peers have in adolescents’ use of tobacco, in some cases promoting use, and in other cases deterring it. The Effects of Smoking on Adolescent Behavior and Their Ability to Perform Well in School Introduction Smoking by adolescents is a social activity and subject to peer pressure. Peers may offer information on where to buy cigarettes and even how to smoke them. Teenagers are often evaluated by the peers as to how cool he or she may be. Popular culture dictates an association between smoking and being a cool kid as much as wearing the right clothes, having a certain haircut, and being friends with the right people. In a since, smoking is a way of reflecting an identity. Knowing this one must ask is smoking by adolescents is really an act they wish to perform. Whether you smoke or not can determine who your friends may be. Kobus (2003) suggests that non smokers tend to befriend non smokers and smokers tend to befriend smokers. Non smokers that do become friends with smokers run a much higher risk at becoming a smoker themselves. Hypothesis In this study, I believe that adolescent who smoke will most likely have friends who smoke. I believe this study will show that 25% of the teenagers polled will be smokers and 80% of them will be friends with other smokers. It will also prove that the non smokers will be less likely to be friends with smokers. Literature Review Kobus (2003) suggests that peer relationships are the primary factor involved in cigarette smoking. Specifically, social learning theory, primary socialization theory, social identity theory and social network theory are discussed. Empirical findings regarding peer influence and selection, as well as multiple reference points in adolescent friendships, including best friendships, romantic relationships, peer groups and social crowds, are also reviewed. Patton, Hibbert, Rosier, Carlin, Caust, and Bowes (1996) state that an association of smoking with depression and anxiety has been documented in adult smokers. Subjects reporting high levels of depression and anxiety were twice as likely to be smokers after the potential confounders of year level; sex, alcohol use, and parental smoking were controlled for. Regular smokers were almost twice as likely as occasional smokers to report high levels of depression and anxiety. In trying to determine whether smoking can influence a student’s school performance, Te-wei, Zihua, and Keeler (1998) report there’s no direct causation from smoking to school performance, but smoking might have an indirect effect, leading to other delinquency behaviors or drug abuse. These behaviors, in turn, could lead to poor school performance. However, the main argument against this hypothesis is that smoking is a relatively common behavior relative to other factors that lead to antisocial behaviors. Methodology Population The population I used in this study of sophomore students in Ms. Powell’s math classes at McCreary Central High. I posted a survey to a web site and have asked all that would to take the survey. Instruments I started my survey by asking a yes or no question: â€Å"Do you smoke? † Then I asked all the non smokers the following 5 questions: 1. Are you male or female? 2. Does either of your parents smoke? 3. Do you feel pressure from your friends to smoke? 4. Would you have a best friend that smokes? 5. What is your average grade in school? Then I asked all smokers the following questions: 1. Are you male or female? 2. Does either of your parents smoke? 3. Do you pressure your friends to smoke? 4. Does your best friend smoke? 5. What is your average grade in school? Data Analysis At the time of writing this draft I have not collected any data yet. I will add this on my final draft. Discussion At the time I am writing the first draft I haven’t had enough time to collect the data for my paper. I have posted my questions using survey monkey to a web page at McCreary Central High where my wife teaches. She is going to ask student from her class to take the survey. So far I have only had 4 people take the survey. This is hardly enough to come to any conclusions. Conclusions In Conclusion, I plan on collecting the date from my surveys to analyze. Kobus (2003) concludes that adolescent peer relationships contribute to adolescent cigarette smoking. Youth who are friends with smokers have been found to be more likely to smoke themselves than those with only nonsmokers as friends. Best friends, romantic partners, peer groups and social crowds all have been found to contribute to the smoking or non-smoking behavior of teenagers. In some cases, peer influences promote smoking and, in other cases, they deter it. The mechanisms of peer influence appear to be more covert and subtle than is thought commonly. That is, rather than be the result of direct and coercive pressures, decisions regarding smoking behavior have been found to reflect predetermined choices about fitting in, social approval, popularity and autonomy. Parents and the media have also been found to contribute to the smoking or non-smoking of youth. References Akers, R. L. , Massey, J. , Clarke, W. , ;amp; Lauer, R. M. (1983).

Rhetorical Analysis of Albert Einsteins Letter free essay sample

His tone, being a strategic method to appeal, and his recognition of all the logical approaches to prayer, being his logos appeal, go hand-in-hand. While he refrains from focusing on himself, he addresses a research scientist as more of a group rather than a specific individual. Einstein logical approaches the idea of scientist and praying: â€Å"Scientific research is based on the idea that everything that takes place is determined by laws of nature, and therefore this holds for the actions of people. After this rather cryptic answer, Einstein attempts to illuminate the best understanding by segregating the ideas of prayer, faith, and religion in a research scientist’s eyes. He does so by admitting that science does rest on faith: â€Å"However, it must be admitted that out actual knowledge of these laws is only imperfect and fragmentary, so that, actually, the belief in the existence of basic all-embracing laws in Nature also rest on a sort of faith. We will write a custom essay sample on Rhetorical Analysis of Albert Einsteins Letter or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page He continues to separate these ides by qualifying to accept religion, but in a way unique to the way religion is seen by â€Å"someone more naive†: â€Å"But, on the other hand, every one who is seriously involved in the pursuit of science becomes convinced that a spirit is manifest in the laws of the Universe†¦Ã¢â‚¬  While Einstein states, â€Å"I have tried to respond to your question as simply as I could. †; his answer is rather convoluted. But with a complex question, comes a complex answer. Einstein does not dumb down his diction for this sixth grader, but more so responds intellectually because someone who finds interest in a complex question would not expect a merely simple answer. This technique Einstein used leaves the student with a comforting mood; Einstein creates a trust by seeming completely truthful in three short statements: â€Å"I have tried to respond to your question as simply as I could. Here is my answer. †, â€Å"I hope this answers your question. †, and â€Å"Best wishes. †

3 Ways To Increase the Pressure of a Gas

3 Ways To Increase the Pressure of a Gas One common science homework question is to list 3 ways to increase the  pressure of a gas container or a balloon. This is an excellent question because answering it helps you understand what pressure is and how gases behave. What Is Pressure? Pressure is the amount of force exerted over a unit of area. P F/A Pressure Force divided by Area As you can see from looking at the equation, two ways to increase pressure are to increase the amount of force or decrease the area over which it is exerted. How exactly do you do that? Thats where the Ideal Gas Law comes into play. Pressure and the Ideal Gas Law At low (ordinary) pressures, real gases behave like ideal gases, so you can use the Ideal Gas Law to determine how to increase the pressure of a system. The Ideal Gas Law states: PV nRT Where P is pressure, V is volume, n is the number of moles of a gas, R is Boltzmanns constant, and T is temperature If we solve for P: P (nRT)/V Three Ways to Increase the Pressure of a Gas Increase the amount of gas. This is represented by the n in the equation. Adding more molecules of a gas increases the number of collisions between the molecules and the walls of the container. This raises pressure.Increase the temperature of the gas. This is represented by T in the equation. Increasing temperature adds energy to the gas molecules, increasing their motion and, again, increasing collisions.Decrease the volume of the gas. This is the V in the equation. By their very nature, gases can be compressed, so if the same gas can be put into a smaller container, it will exert a higher pressure. The gas molecules will be forced closer to each other, increasing collisions (force) and pressure.
