Math Modeling - Essay Example Thus both the subjects are pure creations of the human intellect and exist only in our creative plane of abstraction. In its outset, it seems surprising that there must be a mathematical basis for music, but centuries of mathematical thought form the theoretical foundation upon the modern musicology has been built. All fields of modern mathematics have found applications in musicology – from the simple tuning of instruments and the description of notes to numerical algorithms for tonal temperament. The very description of notes begins with mathematics. All the notes that we are familiar of - A, B, C major, C minor- and so on are ratios of each other. Music is nothing but the harmony of sound waves reaching our ears. Each wave is characterized by its amplitude (which determines its sound or pitch), frequency, shape of its wave envelope, beat and so on. The ‘A’ note for example has a standard frequency of 440 Hz. All corresponding notes until the next octave of 880 Hz are in a fixed ratio to each other (this ratio is the subject of our further discussion). It has been found from our experience that these notes are melodious and when played in the correct combinations create the sensation of music. This description might create a rather mechanistic view of melody but the selection of the right notes is not easy and can come only with deep knowledge, practice and a more than an average talent. String instruments use this manipulation of notes (or equivalently frequencies) to the fullest. A flute produces unadulterated notes. A string on the other hand also produces what are known as ‘harmonics’ of the original notes. A 440 Hz note has its ‘first Harmonic’ at twice the frequency and half its amplitude, the second harmonic at thrice its frequency and a third of its amplitude and so on. This iteration can continue as long as the frequencies are too high to be discerned or the amplitude is too low to be heard. Thus the

Cultural Dimensions Essay Example for Free

Cultural Dimensions Essay 1)Give the definition and objectives of â€Å"your† cultural dimensions (what does the dimension measure? what do you want to measure? For instance : ability to work in groups, individual empowerment (for the individual/collective dimension). Diffuse and Specific orientated cultures – The most apparent difference is the ability to separate private from professional life. In diffused cultures, the private and professional lives are closely linked whereas specific cultures keep them separate. Additionally, specific cultures promote directness, precision, and transparency. Also, people from specific orientated cultures are able to remove themselves from a situation in regards to principles and values. This means that specific orientated cultures encourage objectivity. This is in contrast with the diffuse orientated culture that is more indirect and highly subjective. Furthermore, it can be said that this culture is more informal and social-orientated. 2)Illustrate the dimension referring not only to the professional life. Describe situations in which the dimension may impact behaviors. For instance : when somebody cries in the classroom, (for the neutral/ affective dimension). For example, if a manager is invited to dinner by employees, in a specific-orientated culture, the manager might decline the invitation as he or she wouldn’t feel it is appropriate whereas in a diffuse orientated culture this might be seen as an opportunity to bring informality to the relationship. So in a company based in Germany, this invitation would be seen as inappropriate because Germany has a more specific culture whereas in Finland this wouldn’t necessarily be frowned upon as it is more diffuse orientated. 3)In order to measure â€Å"your† dimension among persons of different nationality, prepare a series or questions (MCQ or Yes/No type are easier to analyze).

The Characters in A Streetcar Named Desire Essay -- A Streetcar Named D

A Streetcar Named Desire is a classic tragedy written by Tennessee Williams, which earned him the Pulitzer Prize as well as many other awards. This brilliant play explores many important themes and issues. The main recurring theme Williams explores to the readers is the conflict between fantasy and reality, honesty and lies. However, sexuality, violence, and social differences also shape the action of the plot, in which they contribute to the effect of the characters of the play. The three main characters, Blanche Dubois, Stella Kowalski, and Stanley Kowalski, have different ways of dealing with the said conflicts in their harsh surroundings in which they live in, as they all face different crisis. Blanche, who suffers from emotional and inner conflict, is caught between two worlds and tries to escape reality and the truth as much as she possibly can with her imagination. Stella on the other hand, is a naà ¯ve and sensitive character, and may be considered to be the protagonist of t he play. Stella tries to ignore the truth going on around her, and as harsh as they may be, she accepts them. Stanley, who is an aggressive, dominant, and sexual character, uses violence to receive his desire, no matter the cost. Throughout this play, Blanche, Stella, and Stanley try to survive and deal with reality in different ways in order to satisfy their desire. Blanche DuBois is the most interesting character in A Streetcar Named Desire. This is because she has an amazing ability of making her fantasy seem like reality. From the beginning of the play, Blanche is already represented as an unstable woman. She has lost her fortune and residence due to creditors, and has turned to her younger sister for nurture. As the play develops, Blanche’s tr... ...of the two worlds was sent to a mental institution. Stanley on the other hand, is a very controlling and brute character. He believes that he is the master of his house and that everything should be going according to him. When he feels like his superiority is threatened, he uses violence to retain his power. He does anything and everything to maintain his dominance. After raping and sending Blanche to a mental institute, he feels that he has completed his revenge from her, and is once again the master of his home and wife. Stella suffers from her husband’s bad temper. Despite that Stanley uses violence to get her to obey. However, she has now accustomed to his aggressive ways and has gotten along with the harsh reality surrounding her. Even after hearing that her husband raped her sister, she chose to believe the guilty and punish the innocent by sending her away.

The Role of Women in Society Essay -- Women Females Society Essays

The Role of Women in Society Women are important in our society. Every woman has her own job or duty in this modern society in which men are still the 'strongest gender';. We can ´t forget that women ´s life is a lot more complicated than a man ´s life. A woman has to take care of her own personal life and if she is a mother , she has to take care also about her children ´s life too. Marriaged women have lots of worries and believe it or not , they carry out a more stressfull life than marriaged men. Several times in my life I have heard commentaries about the lack of importance of women. I am personally against these kind of commentaries. In my life the most important person I remember is my mother. She is a professional also , but besides her profession , she always took good...

Moral Simplification in Disney’s The Little Mermaid

Disney’s Portrayal of Women and Simplification of Morals For most people, the first image that comes to mind when the subject of Walt Disney’s animated movies comes up is the studio’s popular princesses. Ever since Snow White made her debut in 1937, Disney has cornered the market on princesses. One primary topic that critics have discussed in Disney’s films is the way princesses are portrayed. The roles of the female characters are especially drawing the interest of academic critics.Jack Zipes, author of Breaking the Disney Spell, believes that the Disney princesses have regressed. On the other hand, Libe Zarranz, author of Diswomen Strike Back? The Evolution of Disney’s Femmes in the 1990s, and Rebecca Do Rozario, author of The Princess and the Magic Kingdom: Beyond Nostalgia, The Function of the Disney Princess, believe that the Disney princess has progressed. Another aspect of Disney’s movies that catches the eyes of critics is the moral s implification in the films.They believe that the morals from the original fairy tales are being manipulated and simplified in the Disney films. A. Waller Hastings, author of Moral Simplification in Disney’s The Little Mermaid, and Finn Mortensen, author of The Little Mermaid: Icon and Disneyfication, both agree that Disney’s simplification of morals is giving viewers the wrong depiction of life. Disney’s portrayal of women and simplification of morals are giving viewers the wrong impression of life and women. Many critics call the process of simplification in Disney movies, â€Å"Disneyfication. Disneyfication is especially shown in The Little Mermaid. In Disney’s version of The Little Mermaid, Disney retains elements of Hans Christian Andersen’s original fairy tale. A. Waller Hastings notes, â€Å"In the Disney adaptation, the elements of the fairy tale remain recognizable, but superimposed are typical elements of Disneyfication and a happy endi ng that contravenes the moral intention of the original tale† (85). The resistance towards Disneyfication is an agreement between academic writers.Zarranz also notes, â€Å"The dramatic transformation of literary fairy tales, nonetheless, has been problematic, since Disney’s animated fairy-tale adaptations have systematically undergone a process involving sanitization and Americanizaion, two distinctive features to compound the so-called ‘Disneyfication’ of folklore and popular culture† (55). Many critics believe that Disneyfication takes out the sting and variety of the real world. In the Disney world, everything is the same, everything is happy, and everything is full of everlasting hope.Zipes states that, â€Å"The great ‘magic’ of the Disney spell is that he animated the fairy tale only to transfix audiences and divert their potential utopian dreams and hopes through the false promises of the images he cast upon the screen† (2 3). The process known as Disneyfication seems to be giving viewers the wrong depiction of life. Original morals that are shown throughout the original fairy tales are left out when they become â€Å"Disneyfied. † The conclusion that Disney’s â€Å"watering down† of morals of the original fairy tales is an overwhelming agreement among academic writers.Most people applaud Walt Disney and his predecessors for their creations, however many critics have found a particular flaw of moral simplification in Disney films. Mortensen notes, â€Å"The message of the fairytale is conveyed in terms suitable for a modern public but is integrated into a product that cheats its intended public of small children†¦ † (449). Because the morals in the original fairytale’s are seemingly left out of Disney productions, critics view the Disney films as nothing more than simplistic reproductions that give viewers wrong impressions of life.Hastings writes, â€Å"While generally praising Walt Disney’s technical contributions to animated film, critics have been troubled by the studio’s treatment of classic children’s literature and fairy tales† (83). The producers at Disney are giving children an unreal sense of false hope. Disney films are simplified to an extreme that give viewers the wrong depiction of life. The simplistic portrayal of female characters is a specific by-product of Disneyfication. The roles of female characters in Disney movies have regressed compared to Walt Disney’s first films that featured female characters.In Disney’s earliest movie, Snow White and the Seven Dwarfs, Snow White takes on a maternal image. She instructs the dwarves in small, everyday routines such as manners and hygiene, and serves as a mother to the dwarves. The role of Snow White is very simple compared to the princesses of late, and much more realistic. In more recent Disney movies, female characters are shown as prin cesses. While the female characters, such as Snow White, used to be a bit submissive and worldly, over time some critics believe the female character has progressed. Zarranz notes,†Ã¢â‚¬ ¦ ven though it is still a long time before we can speak about successful feminist representations in a commercial icon like Disney, recent films incorporate complex females that are worth taking into consideration† (63). Some female characters are even seen as courageous women admired for their brave deeds in their films. Ariel from The Little Mermaid and Belle from Beauty and The Beast are the start of the more modern Disney princess. Do Rozario writes, â€Å"The Disney kingdom still may seem a man’s world, but it is a man’s world dependent on a princess† (57).While Rozario and Zarranz believe the Disney princess has progressed, Zipes strongly suggests that the princess of late has regressed. Zipes writes, â€Å"The young women are helpless ornaments in need of pr otection, and when it comes to the action of the film, they are omitted† (37). Rozario and Zarranz believe that the female character has progressed because of the role that has been given to the characters. However, they seem to overlook the fact that the princess role is very unrealistic.They also seem to overlook the fact that in almost every princess movie, the female character is relying on a male character. In The Little Mermaid, Ariel gives up her entire life to be with a man. Belle, too, lets go of her former life to be with the Beast. So as Rozario and Zarranz may believe that the more recent female characters are much more strong and courageous than those of earlier Disney films, they seem to have overlooked the flaws in the Disney princess. While Walt Disney and his studios are usually praised, multiple researchers have found flaws in in their creations.The inability to portray women in a more realistic way, and the simplification of morals that Disney produces in th eir films, are giving viewers the wrong impression of life and women in the real world. While Disney probably won’t take the critic’s suggestions into consideration, the critics do propose some very interesting arguments concerning the image of female characters and the simplification of morals.

The Boston Massacre Hero, Crispus Attucks

The Boston Massacre Hero, Crispus Attucks The first person to die in the Boston Massacre was an African-American sailor named Crispus Attucks. Not much is known about Crispus Attucks prior to his death in 1770, but his actions that day became a source of inspiration for both white and black Americans for years to come. Attucks in Slavery Attucks was born around 1723; his father was an African slave in Boston, and his mother was a Natick Indian. His life up until he was 27 years old is a mystery, but in 1750 Deacon William Brown of Framingham, Mass., placed a notice in the Boston Gazette that his slave, Attucks, had run away. Brown offered a reward of 10 pounds as well as reimbursement for any incurred expenses to anyone who caught Attucks. The Boston Massacre No one captured Attucks, and by 1770 he was working as a sailor on a whaling ship. On March 5, he was having lunch near Boston Common along with other sailors from his ship, waiting for good weather so they could set sail. When he heard a commotion outside, Attucks went to investigate, discovering a crowd of Americans clustered near the British garrison. The crowd had gathered after a barbers apprentice accused a British soldier of not paying for a haircut. The soldier struck the boy in anger, and a number of Bostonians, seeing the incident, gathered and shouted at the soldier. Other British soldiers joined their comrade, and they stood as the crowd grew larger. Attucks joined the crowd. He took leadership of the group, and they followed him to the custom house. There, the American colonists began throwing snowballs at the soldiers guarding the customs house. The accounts of what happened next differed. A witness for the defense testified at the trials of Captain Thomas Preston and eight other British soldiers that Attucks picked up a stick and swung it at the captain and then a second soldier. The defense laid the blame for the actions of the crowd at Attucks feet, painting him as a troublemaker who incited the mob. This may have been an early form of race-baiting as other witnesses refuted this version of events. However much they were provoked, the British soldiers opened fire on the crowd that had gathered, killing Attucks first and then four others. At the trial of Preston and other soldiers, witnesses differed on whether Preston had given the order to fire or whether a lone soldier had discharged his gun, prompting his fellow soldiers to open fire. The Legacy of Attucks Attucks became a hero to the colonials during the American Revolution; they saw him as gallantly standing up to abusive British soldiers. And it is entirely possible that Attucks decided to join the crowd to take a stand against perceived British tyranny. As a sailor in the 1760s, he would have been aware of the British practice of impressing (or forcing) American colonial sailors into the service of the British navy. This practice, among others, exacerbated tensions between v and the British. Attucks also became a hero to African-Americans. In the mid-nineteenth century, African-American Bostonians celebrated Crispus Attucks Day every year on March 5. They created the holiday to remind Americans of Attucks sacrifice after blacks were declared non-citizens in the (1857)Â  Supreme Court decision. In 1888, the city of Boston erected a memorial to Attucks in Boston Common. Attucks was seen as someone who had martyred himself for American independence, even as he himself had been born into the oppressive system of American slavery. Sources Langguth, A. J.

Glenn Seaborg essays

Glenn Seaborg essays There are many great chemists in this world; one of the greatest is Glenn T. Seaborg. Before he reached the age of 40, he won the Nobel Prize, he discovered radioisotopes that are used to treat millions of cancer patients, he founded the element that makes atomic bombs explode, and many people sought out his advice. Seaborg also holds the Guinness Book of World Records for the longest biography in Who's Who in America. There is no doubt that Seaborg was a brilliant man, and will never be forgotten. Seaborg was born on April 19, 1912 in Ishpeming, Michigan. Ishpeming is a small iron-mining town in the Upper Peninsula of Michigan. Seaborg was of total Swedish decent. His mother was Selma Olivia Erickson, his father Herman Theodore Seaborg. Seeing as how his parents were Swedish immigrants Glenn learned to speak Swedish before he learned English. When Glenn was ten years old his family decided to sell all of their belongings. They bought one-way tickets to California, in hopes of providing a better life for Glenn and his younger sister Jeanette. Seaborg then attended Watts high school, in the suburbs of Los Angeles. The school was racially and ethnically diverse. This helped Seaborg in his later years to be able to interact well with many different people. It was in Seaborgs junior year that he was introduced to chemistry, and found his lifelong love. The man to introduce him to this was his science teacher Dwight Logan Reid. Seaborg worked his way through college. He was able to pay his undergraduate tuition at UCLA by working as a stevedore, a farm laborer, and an apprentice Linotype operator for the Los Angeles Herald. He was elected Phi Beta Kappa in his junior year of college and was graduated in 1934. Seaborg transferred to the University of California-Berkeley for his graduate studies. In 1937 Seaborg received his Ph.D. in chemistry, but it was a year earlier that his career as a nuclear chemist actually begun....
