Quantitative Methods for Business Essay Example for Free

Quantitative Methods for Business Essay In January 2008, Northern Airlines merged with Southeast Airlines to create the fourth largest U.S. carrier. The new North-South Airline inherited both an aging fleet of Boeing 727-300 aircraft and Stephen Ruth. Stephen was a tough former secretary of the navy who stepped in as new president and chairman of the board. Stephen’s first concern in creating a financially solid company was maintenance costs. It was commonly surmised in the airline industry that maintenance costs rise with the age of the aircraft. He quickly noticed that historically there had been a significant difference in the reported B727-300 maintenance costs (from ATA Form 41’s) both in the airframe and engine areas between Northern Airlines and Southeast Airlines, with Southeast having the newer fleet. On February 12, 2008, Peg Jones, vice president for operation and maintenance, was called into Stephen’s office and asked to study the issue. Specifically, Stephen wanted to know whether the average fleet age was correlated to direct airframe maintenance costs, and whether there was a relationship between average fleet age and direct engine maintenance costs. Peg was to report back by February 26 with the answer, along with quantitative and graphical descriptions of the relationship. Peg’s first step was to have her staff construct the average age of Northern and Southeast B727-300 fleets, by quarter, since the introduction of that aircraft to service by each airline in late 1993 and early 1994. The average age of each fleet was calculated by first multiplying the total number of calendar days each aircraft had been in service at the pertinent point in time by the average daily utilization of the respective fleet to total fleet hours flown. The total fleet hours flown was then divided by the number of aircraft in service at that time, giving the age of the â€Å"average† aircraft in the fleet. The average utilization was found by taking the actual total fleet hours flown on September 30, 2007 form Northern and Southeast data, and dividing by the total days in service for all aircraft at that time. The average utilization for Southeast was 8.3 hours per day, and the average utilization for Northern was 8.7 hours per day. Because the available cost data were calculated for each yearly period ending at the end of the first quarter, average fleet age was calculated at the same points in time. The fleet data are shown in the following table. Airframe cost data and engine cost data are both shown paired with fleet average age in that table.

Mozart :: essays research papers

A short time before the death of Mozart, a stranger of remarkable appearance, and dressed in deep mourning, called at his house, and requested him to prepare a Requiem, in his best style, for the funeral of a distinguished person. The sensitive imagination of the composer immediately seized upon the circumstance as an omen of his own fate; and the nervous anxiety with which he labored to fulfill the task, had the effect of realizing his impression. He died within a few days of completing this magnificent piece of music, which was performed at his interment. Mozart's unfinished Requiem has long been shrouded in mystery. Mozart undertook the commission for an Austrian nobleman, little knowing that he was to write a requiem for himself. Inevitably, the secrecy surrounding the anonymous commission, the circumstances of Mozart's death, the unfinished state of the work, and its completion under the direction of Mozart's widow, Constanze, have precipitated two centuries of romantic speculation and scholarly controversy.   Ã‚  Ã‚  Ã‚  Ã‚  One book that further explores the history and an analytical study on the Requiem is Christoph Wolff’s Mozart’s Requiem. Christoph Wolff provides a critical introduction to the Requiem in its many facets. Mozart’s Requiem has been a topic discussed for centuries and in Wolff’s book that topic is meticulously broken down. Wolff breaks the book down in two parts. Part I of his study focuses on the tangled genesis and completion of the work and its fascinating early reception history until Constanze's death. Wolff summarizes the current state of research on the subject, provides new perspectives on Mozart's conception of the whole work, and surveys his contributions to the movements composed by his assistant, Sà ¼ssmayr. Part II provides a musical analysis of Mozart's composition, including contextual, structural, and interpretive aspects.

The Challenges between a Muslim and non-Muslim after 9/11

There is tremendous tumult of voices after the news was aired. The media was centered on the busiest city of the world – New York. Even today many have not failed to raise a pen, even poets, artists, students and professionals, the unlearned and learned all are in awe. The sad destiny of those who perished at the Ground Zero can not be erased in memory and much more to those who were left behind. These are the Muslims and non-Muslims who still survived but are now living in the ashes of indifference, of terror and pain. Many are written about the issue but the three articles of Aidi, Marty and Asani is worthy to be discerned.The first article challenges plurality and the other speaks about fundamentalism and the last one equates Pan-Africanism to Islam. All of which are beliefs not only in terms of religion but a very specific knowledge by which man go through life which transcends his earthly existence. More than seven years ago, The Ground Zero boasted for its twin towers, e ach earthly dominion rested on their laurels, there could be havoc around on some parts of the world but a non-Muslim and a Muslim could occupy the same space without qualms or pretence.After the 9/11 when thousands of American citizens were slain, killings had also begun to the so called perpetuators akin. Vehemently, even if sin is personal the debt would be somehow carried on to the next generations. Man by destiny always inherits the sin of his first parents, as any good works are wagged which serves as inspirations for the younger ones? The challenges that Muslim and non-Muslim faces today is on how each one of them foster universality among their many diverse beliefs and how to remove the fears that those beliefs brought about which was clouded by the strand of hatred and ignorance.Today, co-existence between a Muslim and non-Muslim presupposed a barrier an unequal yoke so may say. The catastrophe left a mark of indifference that is antagonistic to both and it is no longer the hues we talked about but the creed of one nation between another. Succinctly, Muslims are even called the new niggers of today’s world of discrimination (Aidi, 2002). Moreover, it is not easy to justify pain because in the last analysis it is an evil that must be eradicated by all costs.It is only divine wisdom that can only justify pain and somehow alien to an understanding of a regular man. To the Muslims, a life well lived will serve as an example that his belief is not erroneous and he in his own belief wishes to co-exist with others. His belief in the Quran in the days that will come will be a challenge of its authenticity that the â€Å"noblest among you is the most god-fearing of you. (Quran 49:13). † Essentially when we say god-fearing man is the respecter of truth.Muslims, young and old is challenge by the world to live by its faith, and if god-fearing why the erroneous doctrine of that lone killer pilot blown in a blaze those two Manhattan skyscrapers? When in Quran 111 God is a respecter of freedom. God created man differently so that they may know and understand each other (Asani, 2003). The Muslims who have submitted to the truth has a great relevance to show the world the real essence and truth of their beliefs. They are the ones who should stand up and defend their faith on those who uses religiosity for personal gains and politics.Non-Muslims on the other hand, must seek the truth in defiance of prejudices and other extremes, with his Muslim brothers he must defend peace and pluralism that the country had earnestly guarded throughout the centuries. The Americas should test where he’s ground stand, if it is solid and firm and if its faith still rest in God. Non-Muslims, Christians and non-Christians and even due to ignorance are disbeliever of God, in the virtue of wanting to exist he must also be respectable to the life of others behaving in a fashion that still welcoming even in the face of odds.Martin Marty elaborated in his work â€Å"the Future of World Fundamentalisms† that we must make eschatological verifications or reaffirm if a movement does not lead to a polity that runs on compromises or any revivalism or reactivation of a militant Islamic tradition (Marty, 1998). Reactive agents according to Marty are inconspicuous, adaptive and improvisatory but are directly assertive. It is good to know what is under those rubrics of belief, whether that so called useful knowledge does not disdain its members of uncongenial acts worthy of suspicion.It is always good to know the wolf inside the sheep skin because a terrorized world can not afford to make the same mistakes again. Muslims and non-Muslim have one in common and that is to decipher the truth not only in terms of their religiosity and beliefs but on how each and every one lives a life of normal existence. The greatest challenge for the Muslim and non-Muslims in the post 9/11 is to unite in bringing this world to peace so the lives lost in the catastrophes are not wasted. Both must survive the struggle to be whole again in the fight of terrorism.Each one in whatever state in life must still nurture the gift of patience and kindness despite of confusion that is going on in this world. Man’s religion may have existed since civilization began and the only real truth about it was that the difference between a supernatural and human beliefs. Human beliefs tend to materialism and are bounded by space and corners while supernatural beliefs, leads to freedom and love. In fact, love is the only thing that stands still when all else has fallen.And only a true religion bears this sign. Charity removes obstacles, it builds bridges and any learning that is void of this elementary truth is a deceit. This is a great challenge not only to Muslims or non-Muslims to non-believers or future converts but to the whole world at large. Love makes a great difference to what is it that differentiates a human from a beast form and a goodish from a noble being. For a Muslim and a non-Muslim, there is no reason to fear because in their hearts the truth is already been written.

The Internet And The Way We Live - 2446 Words

The Internet and the Way We Live That the internet has revolutionized the way humans carry out their daily routines is an understatement. People of the 21st century are better interconnected than those of any other time in the history of man. This has especially been facilitated by the social media sites, texting, instant messaging, and checking headlines regarding different stories on the web (Carr, 2010; GreenBlatt, 2010). Undoubtedly, the internet has become central to every aspect of human life. The internet is in shopping avenues, at work places, areas of socialization, and even in the entertainment arena.
