Egalitarian Relationships in Radical Heterosexuality Essay

In this article the author Naomi Wolf does a great job in explaining radical sexuality. Also known as egalitarian relationships. In marital relationships, the meaning is typically that husband and wife have equal status in the marriage. That is sometimes defined as having equal power. She talks about there being some conditions to abide by. For example, it requires that women should be able to support themselves without the help of any man. Also the man must yield the automatic benefits presented by gender. Women give up gender benefits as well as the men. By day they fight gender injustice; by night they sleep with men (Wolf p. 155), she questions weather feminists who are in a heterosexual relationship are contradicting themselves,†¦show more content†¦In conclusion, Wolf explains that it is perfectly ok to be a feminist, hate sexism and love men. Men were able to do just about anything they wanted with their wives, until the womens movement and even then in some parts of the countries it is still the same. Prior to the Civil War married women had many duties but few rights. They were not permitted to control their property, even when it was theirs by inheritance. A husband had the right to his wifes wages, to decide on the education and religion of their children, and to punish his wife if she displeased him. (Janice M. Steil). In addition, it shows how men always over rule women. Naomi Wolf also talks about how women were not treated as human. For example, she says, In the nineteenth century, when a judge ruled that a husband could not imprison and rape his wife, the London Times bemoaned. Also, she mentions the English common law that said, a man could legally beat his wife with a switch no thicker than his thumb, and thats where she says we got the phrase rule over thumb. It seems incredible to me that they treated women that way. What most feminists want is the marriage where their partner is showing respectful treatment towards them and their children, a kindness rather than a legal right such as before or in other countries today. Therefore, All the rules that men laid down over the centuries have recently gone out the window, and were

Robert Louis Stevensons Impact on British Literature

Robert Louis Stevenson ranks in the upper echelons of writers in British literature. He is one of the most popular writers of the nineteenth century. Stevenson had a great range of skill in producing works in the form of poetry, plays, short stories, essays and novels. A variety of aspects of his very own life and personal experiences were implemented into his literary works. The romance novel is that of which he is best became known for. His works are still studied and observed in today’s society. While he is not regarded as â€Å"the best† writer in British history, his work still demands respect and deserves appreciation. Robert Louis Stevenson was a talented literary artist that had a significant impact on British literature. Born†¦show more content†¦It was understood that while at the University of Edinburgh, Stevenson would be studying engineering. After his studies, Stevenson’s father hoped that he would begin his profession with the fami ly firm and follow in his father’s footsteps (The RLS Website). Stevenson, however, had a much more â€Å"romantic nature† within him, and while supposedly studying for a degree in science and engineering, he spent a majority of his time reading and studying French Literature, Scottish history, and the works of Charles Darwin and Herbert Spencer (Poem Hunter). In his twenty first year, Stevenson declared his intention of becoming a writer to his father, Thomas. He received strong opposition on the matter from his father, however (Encyclopedia of World Biography). Stevenson and his father then agreed to a certain type of compromise. His father would agree to accept his intentions to pursue a career as a writer, but would study for a career in law so that in the case that Stevenson’s career as a writer was a failure, he would at least have a profession to fall back on (Poem Saver). Stevenson was admitted to the Scottish bar in 1875 (Encyclopedia of World Biography). He â€Å"passed advocate† in 1875 but did not even bother to take time to practice because he had made it clear to himself that he wanted to be a writer by then.

Holocaust Sociology Free Essays

Gevorg Petrosyan Professor Wonser Intro to Sociology 23 June 2012 Final Project, Assignment 2: Nazi Germany and Holocaust The Holocaust was the genocide of around six million European Jews during World War II. (Holocaust History) Nazi Germany led by Adolf Hitler had targeted every single Jew to be perished. Unfortunately Nazi Germany succeeded to murder two-thirds of the nine million Jews who were stationed in Europe. We will write a custom essay sample on Holocaust Sociology or any similar topic only for you Order Now (Holocaust History) The Holocaust can be viewed at in many sociological perspectives of the sociologists mind. Adolf Hitler used everything in his power to exterminate any non-German ethnic that lived in Germany. Hitler) Authority played a key point in the Holocaust against the Jews. The following are the many perspectives of this horrific act against humanity. One of the main sociological perspectives that fall into Nazi Germany and how Holocaust was looked at was social stratification. The Aryan race was supreme; anybody else was lower then they. (Nazi SS) Jews, homosexuals, handicapped, prisoners of war, and minority groups were all prosecuted. As talked about in lecture, Max Weber’s theory of social class portrayed Adolf Hitler’s wealth, power, and prestige. Hitler used these components to his advantage and started an empire. Brainwashing Germans to hate and murder humans that are not in their â€Å"social class†, as said the Aryan race. Social class and inequality played a big role for the non-Aryan. Everything was stripped away from them such as cars, money, children, clothes, food, and eventually their hope. The people of culture of poverty had strong feeling of not belonging, helplessness, no faith, and all hope was gone. Jews and others were treated as aliens or non-humans. Adolf Hitler was a functionalist in my point of view because in that way he would think social stratification was both natural and beneficial to society. He promoted deviance in the way of the labeling theory. If you are not Aryan or German you are not welcome and also considered as a threat. (Nazi SS) In that case you are labeled through judgment and that changes the way others respond to you. Another labeling theory in the Holocaust was the yellow Star of David patch. This patch often put against right side of the chest, implemented and labeled the person as a â€Å"Jude†. Nazi persecutions used this to label to their prosecutors in an organized way. (Nazi SS) With this patch you had implanted in your mind that you are going to die. It was intended to be the badge of shame and now the public knew you as a Jew. The Jude community was treated like dogs; they were given a name and badge similar to dog tag or collar, and looked upon as animals. Erving Goffman’s term of stigma was given to the Jewish because of their social attribute. Nazi Germany used all three types of stigma in their society such as physical for the impaired or handicapped, moral for mentally challenged, and tribal for Jewish and other non-Aryan or German. The Erving Goffman’s term of stigma was lectured in class. Nazi Germany was big in-group created by Adolf Hitler. They felt loyalty and brotherhood towards each other. Anyone besides them was a major out-group, such as the Jews. The rivalry and hatred they had for the Jews was a usual thing by other fellow Nazi. Such a big in-group had and influence on any Nazi to believe what they were doing is right. Group cohesion strongly powered the Nazi for the loyalty and solidarity. All the members felt strongly tied to each other as family in a way. Any one else was not like them and was to be treated differently. Adolf Hitler’s social influence was the image to all Nazi. His social influence gave them their individual attitudes and behaviors towards others. This became ideal for a dictator, because the group norms made the members want to gain acceptance to their own country. Any negative sanctions were looked down upon and so Germans followed one after another into agreement. Weber’s idea of charismatic authority fell into the category of Adolf Hitler. Adolf Hitler served in the army and soon enough became known as the â€Å"Furher† of Germany. (Hitler 1) Hitler’s demanding voice and humorless speeches dominated audiences. He had all the qualities of a leader from the minute he was born. He didn’t like taking orders from his own strict father. (Hitler 1) Hitler also had many bureaucracies under him, such as the SS. The Schutzstaffel translated to Protection Squad was responsible for many of the crimes towards humanity during World War II. Heinrich Himmler was in charge of a vast bureaucratic empire. He was responsible for the SS, as well as the municipal police. (Nazi SS 4) The SS was feared amongst all Jews because of their deadly rules and punishments. These bureaucracies were so useful to the empire because they ran all the operations needed for power. Hitler used them to keep order and organization between the country, plus not to get his hands dirty. The Nazi Empire and Holocaust was made up of many total institutions. First one would be the military; Hitler knew he had to get the military on his side and soon will obey any command. Soon the military had a mortification of self in which they were brainwashed to dehumanize Jews. They were taught to have â€Å"racially pure† Germany and life. (Chronicle 2) The Holocaust wasn’t carried out by crazy or unusually violent people. The SS deliberately tried to ensure that those responsible for the actual killings were not especially eager, or emotional. They wanted the task to be as business-like and impersonal as possible. (Nazi SS 4) People stop worrying about what the ‘right’ thing to do is because the right thing is always to do what you’re told, and that was because of discipline and authority. Another total institution would be the death camps or also known as concentration camps. Which norms or laws were among the prisoners society? The prisoners had a whole new social life. Resocialization took an impact on them to which fighting for survival was needed and communications between prisoners and officers. Some type of achieved status controlled the whole environment of the prisoners and changed their outlook on life, which soon enough became a mortification of self. Prisoners under hunger, extreme working conditions, and terror of death mortified one to go toe extreme lengths of survival by obeying every rule given or going slowly insane to the point of no return. (Chronicle 2) One of the most disastrous theories for the Holocaust would be dehumanization. What people failed to realize why the Holocaust happened was because what the people were enabling each other to do. (Holocaust History 3) All they did was gather statistics and data and didn’t realize that it was human beings for those stats. The order is different from the act because the person who gave the order doesn’t interpret in their head what kind of order they just gave and the action part of it. The generals and Nazi didn’t focus on the fact that they were committing mass murder to a great amount of human beings with families and connections. There actions weren’t â€Å"bad† at the time so no problem in doing it but when later on in life they realize what they’ve done is very different outlook. The Holocaust would have been impossible without the advancements of modern society. The slaughtering of Jews and other was just like a factory but instead of producing goods, it was producing death. Without modern industrialization and technology they would have never killed mass amounts of people that fast. Gas chambers, trains importing prisoners, concentration camps, not much food source for prisoners, and workload were all components to modern society. Chronicle 3) This is what moved the genocide to speed up its movement of extermination. Letting Adolf Hitler get to his achieved status brought up to Holocaust idea. Without letting him get to this status of â€Å"Furher†. He would not turn a great country into a mass murdering empire of bureaucracies. His speeches, authority, leadership skills, and d iscipline is what made the Nazi Empire what it was. His authority and discipline is what made the soldiers make the choice they made. Why did Hitler target the Jews mostly? Why not another race? He blamed Jews for everything that happened within the country such as lost of World War I, and for the Great Depression. (Hitler 1) He also hated Jews because he regarded them as mostly Communist. (Hitler 1) Society killed the Jews because of their statuses and way of life. Jews were the most significantly affected by the Holocaust but others were targeted too. These included political opponents, soviet prisoners of war, communists, homosexuals, mentally challenged, non-Aryan, and gypsies. Holocaust History 3) They labeled it as â€Å"people that were killed in Holocaust† and didn’t seem to realize how it affected those peoples families and friendships. To this day Jews still mourn over the six million that died. Germany also takes in the guilt of what their country has done in the past. The Holocaust affected such large numbers and was one of the most mass killing genocides. It is taught all around the world in textbooks and classes. Society revo lves under it because now Jews are looked at differently even if they deny someone doesn’t. How to cite Holocaust Sociology, Essay examples

Plastic Surgery Essays - Plastic Surgery, Ancient Egyptian Medicine

Plastic Surgery Plastic Surgery People today are not satisfied with their physical appearance. Whether it is their weight, breasts, facial structure, or buttocks, there is always something they wish was different. As a result of this, many people turn to make-up or push-up bras. Some think that a different route is easier, plastic surgery. A study done by the International Society of Aesthetic Plastic Surgeons shows that, in 2011, 15 million people across the globe turned to plastic surgery to enhance their looks (Bates). Although many people turn to plastic surgery for better physical appearance, it is not the right decision a person wants to take. Plastic surgery costs a fortune and its an addiction, causes illnesses and possibly death, and it is a slow healing process. Plastic surgery deals with the repair, reconstruction, or replacement of physical defects of form or function involving the skin, musculoskeletal system, hand, extremities, breast and trunk, external genitalia or cosmetic enhancement of these areas of the body(Kita). It might look all too nice to get a plastic surgery done and changing the form or appearance of your body part for ever, its procedures usually cost a lot of money to get it done, so its not something that everyone can have, Its usage is limited to those belonging to the high echelons of the society. Furthermore, plastic surgery has the potential to become an addiction. Some people who undergo it become attracted with the outcome and look forward to a change in each and every part of their body. As such, plastic surgery becomes an obsession for them, rather than just a means of modifying a body part. When someone does unnecessary plastic surgery they begin to look abnormal which then leads to addiction. The case of 'revi sion' i.e. getting back the old look has become a common phenomenon in the present times. This is mainly because the result of the plastic surgery might not turn according to your desires. As a result, more and more patients are undergoing revision, after the surgery, to get back their original look. ...Some people suffer from a condition known as body dysmorphic disorder. Persons with this condition can be extremely good-looking, but view themselves as ugly. They equate happiness with beauty. Thus, to achieve a happy state, they undergo repeated cosmetic surgeries. Unfortunately, people with this disorder are never satisfied with their appearance(Higuera). Death can be caused by plastic surgery. There are many risks to be aware of like infection, nerve damage, scarring, and many more. Many celebrities have died from plastic surgery. Though rare, possibility of death cannot be ruled out during plastic surgery. The surgical process involves usage of chemicals and equipments that are not suitable for a persons body. Excessive bleeding, heart attack or even a drop in blood pressure, while the surgery is going on, are some of the things that might lead to death of the patient. All surgeries carry a risk of infection. In some cases, nerves may be damaged or severed during any surgical procedure. The result is more obvious, however, if it is a facial nerve. When those nerves are injured, the outcome can be the inability to make facial expressions or drooping of the eyes (ptosis) or mouth. Scarring is one of the greatest risks to achieving an attractive outcome, scarring is not always predictable, but can be controlled in most cases. Scarring is a possible disadvantage of plastic surgery. These scars are thick and red, they usually dont fade like most surgical scarring. Bruising and swelling for a period of time after the surgery are often difficult to hide, especially when the work was done on the face. A hematoma is a collection of blood outside of a blood vessel.it can develop after surgery, this typically results in an area being swollen and bruised in appearance, with a pocket of blood beneath. In some cases, this is minor, but a hematoma can be large enough to cause pain and even decrease blood flow through the area. In the case of a large hematoma, the surgeon may choose to remove some of the collected blood with a syringe or other similar method. The site of hematoma can present a firm

The Use of Tone in Man of La Mancha Essays

The Use of Tone in Man of La Mancha Essays The Use of Tone in Man of La Mancha Essay The Use of Tone in Man of La Mancha Essay In the play, Man of La Mancha, written by Dale Wasserman, a conglomeration of techniques is used to set or change the emotional feel of a scene. Lighting is lowered to create a sinister feel, or to show that that scene is in the prison, and sometimes it is increased in order to portray joy, or show that the scene is in the poet’s story. Musical crescendos and decrescendos are also used to show this. But even more important than these, are the tricks used by the actors themselves. Blocking, body language, and emotion are all very important, but one specific thing that I noticed was the tone of the performers. In the scene with the barber, the gypsy girl, and the â€Å"Golden Helmet of Mambrino†, the barber’s confusion and slight fear can be clearly heard, even through his minimal lines. Also, the profuse sincerity of Sancho Panza, not to mention his worry for his master, is clearly expressed in each and every of his scenes, especially the opening scene Cervantes’ tale and the final scene where Don Quixote dies after being reunited with his Dulcinea. Even while singing, (I Really Like Him) his tone and emotion remained consistent with the feel of the scene. The actor’s tone also remains constant to his character throughout the play, never becoming too brusque, or too insipid. Mainly though, the character with the most control over, and who had the best use of his tone, was Don Quixote. In the scene, for example, where Don Quixote is faced with the Knight of the Mirrors and his attendants, his cries of agony at the realization of his situation perfectly depicts the terror which is meant to accompany it. His sadness on his deathbed, his ecstatic joy in the recovery of his memories, and his humility when begging to be officially knighted, are all perfectly portrayed, primarily by the tones he uses to emphasize what he is saying. You can truly believe that he is dying, or remembering his love, or believes that the hotel is a fortress, and it’s landlord , a king. It takes many parts to make a play successful. The following of cues, memorization of lines, and the timing of special effects are all important. On a deeper level, the actor’s concentration, dedication, and skill levels are also crucial. A key part though, which can make or break the play, is the actor’s tone when he or she says her lines. With the incorrect tone, the scene feels wrong and the illusion of the play is broken. In this rendition of Man of La Mancha, the actors placed their tones perfectly, which successfully brought forth the underlying messages in the story, which are usually unintentionally omitted.

QA How and Why Should I Keep Track of Time on the SAT or ACT

QA How and Why Should I Keep Track of Time on the SAT or ACT SAT / ACT Prep Online Guides and Tips If you want to do well on the SAT or ACT, keeping track of time and how many questions you have left is extremely important. Sections are 35-60 minutes long on the ACT and 25-65 minutes long on the SAT. One of the leading reasons students perform poorly on either test is that they run out of time. And one of the leading reasons students run out of time is not because they're not aware of how much time is left. We'll go over the best way to keep track of time on the SAT/ACT in this article, including what timekeeping devices are and are not permitted on test day. Q: How Does Knowing How Much Time Is Left Help Me? Answer: It lets you plan out which questions to answer first. For each SAT/ACT section, most people agree that it's strategically best to start with the questions that are easy for you. You can then go back and answer the harder ones in an order that depends on how much time is left. If you have three hard questions and 15 minutes left, it probably doesn’t matter what order you do them in. On the other hand, if you only have five minutes left to do three hard questions, you should try to do the easiest-looking one first. But you can’t even make that choice if you have to rely on having a good view of the big clock on the wall or on the proctor's desk. Q: What Can I Bring to Time the Exam Sections? Answer: Not much. Unfortunately, neither test is very accommodating when it comes to timing devices. Both the SAT and the ACT have the following strict rules about what you can bring to the test. Rule 1: You Can't Bring a Cellphone This is for real. You are technically not even allowed to have a cellphone with you in the room, and you're certainly not allowed to look at your phone during the test or during the breaks in between sections. In practice, if you do take your cellphone with you to the testing center, you must make sure it is completely turned off. If you want to be really safe and know how to take the battery out of your phone, do it. Silent mode just isn't safe enough for the SAT or ACT. We say this because cellphones, even on Silent or Airplane mode, can beep or vibrate loudly for various reasons, from a national weather alarm alert to a software update that restarts the phone. And if your phone goes off, the test is over for you. Your test booklet will be confiscated and disqualified from being scored. More pertinently, even if you bring a cellphone with you to the testing center (which, again, is technically not allowed), you definitely, definitely can not use your cellphone, even just as a timer. Rule 2: You Can’t Bring Separate Timers The College Board explicitly lists "separate timers of any type" as something that cannot be brought in. This means no stopwatches, no kitchen timers, and no hourglasses. An hourglass is not an acceptable timekeeping device for the SAT or ACT. Rule 3: You Can't Bring Anything That Beeps If you use a beeping watch in a way that doesn't beep, it should be fine for the SAT/ACT. However, are you sure you won’t accidentally hit a button that makes it beep? Sure enough to bet your entire SAT or ACT score on it? The only way to guarantee your test won't get disqualified is to play it safe and just bring a watch that cannot make a beep. Q: What’s the Best Plan for Keeping Track of Time on the SAT/ACT? Answer: Use an analog (non-digital) watch that can’t beep but that you can easily reset. You can get a cheap non-digital watch for less than $15 on Amazon. If you’re not great at reading clocks, you can get an easy-to-read one that has the minutes marked on a ring around the watch face. Once you have your analog watch, practice using it as a timer with either of these two strategies. Strategy 1: Set Your Watch to Noon Right when each section starts, set your watch to 12:00 (so that the minute and hour hand are both on the 12). The minutes past 12:00 tell you how many minutes passed since the section started. It's an easier way to check how much time has passed than doing the mental math of, "So we started at 10:48, and it's 11:04 now, which means...16 minutes have passed? Probably?" The main problem with this method is that you still have to do some mental time math. For instance: "The 25-minute SAT Math No-Calculator section started at 12 pm and now it’s 12:07pm. How many minutes do I have left?" The answer is 18 minutes, but the time it took you to do the math in your head is lost time you could've been spending on the test. Save your math for the Math section and use this next trick. Strategy 2: Use Your Watch to Count Down to Noon An alternative to setting your watch exactly to noon is to set your watch to a section's length before the hour. For instance, if the section is 25 minutes long, set your watch to 35 minutes past the hour (which is 25 minutes until the next hour). The watch’s countdown to the end of the hour will also be a countdown to the end of the section. Here's a handy table with the times you should set your watch to at the beginning of each section: Section Length (minutes) Set your watch to... What sections are this length? 25 11:35 SAT Math (No Calc) 35 11:25 SAT Writing and Language, ACT Reading, ACT Science 40 11:20 ACT Essay (optional) 45 11:15 ACT English 50 11:10 SAT Essay (optional) 55 11:05 SAT Math (Calculator) 60 11:00* ACT Math 65 10:55* SAT Reading *To keep the countdown to noon consistent across all sections, it's better to use 11 and 10:55 here, but you could theoretically use a different time if you wanted. Setting your watch to count down to noon is helpful because: You effectively have a timer, giving you an edge. It's completely within policy, since you are allowed a non-beeping watch. It's better than doing time math. Of course, if you use this method, don't forget to reset the watch at the beginning of each section. And when the test is over and you’re out of the test room, set the watch back to the real time. What’s Next? Take advantage of your new knowledge of how to keep track of time by reading our tips on saving yourself time during the SAT. Still worried you'll run out of time? We have more great tips on how to avoid running out of time on SAT/ACT Reading and SAT/ACT Math. How long exactly are the SAT and ACT, anyway? Find out with our guides to how long (with breaks) the SAT and ACT are.

Music Technology Coursework Example | Topics and Well Written Essays - 1000 words

Music Technology - Coursework Example +4dBu is generally found in professional level equipment such as public address systems. Finally, -85dBu indicates the level of noise floor (residual electronic noise) in the sound amplifying system. Noise floor is the measure of the lowest audible sound that can be amplified by the system. Collectively, the three levels are known as the operating line levels of an audio system (Glenn, 1998, p.731). A.2. What do the ranges of 24 dB, 89 dB and 109 dB indicate? Explain the function that each of these ranges has in an audio system? (9 marks) The range 24dB in the diagram indicates the headroom of the sound system (peak level- nominal level) = +28dBu-(+4dBu) =24dBu. According to Rossing (2002, p.168), the main function of this range is to describe the capacity of the sound amplifying system to handle loud sound peaks. For example, a sound system with a larger headroom range is often able to handle significantly louder sound peaks before the sound is distorted or broken. On the other hand , 89 dB range shown in the diagram indicates the S/N ratio (Signal to Noise ratio) of the sound amplifying system. Generally, S/N ratio refers to the difference between the nominal level of the sound system and the noise floor. When the S/N ratio is combined with the headroom, the result is known as the dynamic range assuming that there is no signal below the noise floor in the sound amplifying system (Borwick, 1980, p.45). ... gard, the dynamic range of the system function as the indicator of the difference between the electro-acoustic noise floor and the peak output level of the audio system. B. Why does the graphic refer to two different kinds of dB? Explain both types extensively using formulas for both types too. (15marks). The graphic diagram refers to the two types of dB namely the dB (SPL) and dBu scales. With regard to the dB (SPL), the primary variable measured is the sound pressure level in the audio system. This kind of dB is achieved by measuring the ratio amplified input signals using the logarithmic formula: 10  log  (P2/P1)  dB   Ã‚  where the log is assumed to base 10. (Rossing , Moore , Wheeler, 2002, p.87). The other type of dB used in the diagram is dBu which generally indicates the output of the sound amplifying system (amplitude ratios). dBu is the unit measure of the absolute value of the electrical potential of the system in volts (relative to the sound produced). The formula for this kind of dB is: 20 log10 (V/ V0) = 20 log10 (V/ 0.7746), where voltage is measured using root mean square (Glenn, 1998, p.851). ` C. About the values showed above, would you considered this to be a professional system or only a home-made-like system (e.g. cassette or vinyl) based)? Explain your choice. (5marks). According to the values given in the diagram, the system illustrated is most likely to be a professional system. For example, headroom of 24dB is capable of ensuring high fidelity sound that is only found in the professional sound amplification systems which are often comparatively more sophisticated than the normal homemade systems like those using vinyl and cassettes. Additionally, the large dynamic range indicated in the diagram is a likely suggestion that the system has a high
