Pink Floyd The First Band In Outer Space Essays -

Pink Floyd: The First Band In Outer Space For many people, the group Pink Floyd is considered as un-popular, aged, and without any sense in today's modern society. It's so unfortunate that true rock and roll music is being left behind for the new head-splitting garbage that infests the airwaves today. The newest generation is unaware of the history behind all the music they listen to now. Where did it all begin? Who first wandered into the realms of psychedelic music to create a style and a culture that would last for decades, and never be copied? The answer of course is Pink Floyd Pink Floyd was the first band in outer space. Since the mid-'60s, their music has relentlessly tinkered with electronics and all manner of special effects to push pop formats to their outer limits. At the same time they have wrestled with lyrical themes and concepts of such massive scale that their music has taken on almost classical, operatic quality, in both sound and words. While Pink Floyd is mostly known for their extravagant concept albums of the 1970s, they started as a very different sort of psychedelic band. Soon after they first began playing together in the mid-'60s, they fell firmly under the leadership of lead guitarist Syd Barrett, the gifted genius who would write and sing most of their early material. The Cambridge native shared the stage with Roger Waters (bass), Rick Wright (keyboards), and Nick Mason (drums). The name Pink Floyd, seemingly so far-out, was actually derived from the first names of two ancient bluesmen (Pink Anderson and Floyd Council). And at first, Pink Floyd were a much more conventional act that the act into which they would evolve, concentrating on the rock and R&B material that were so common to the repertoires of mid-'60s British bands. Pink Floyd quickly began to experiment, however, stretching out songs with wild instrumental freak-out passages incorporating feedback, electronic screeches, and unusual, eerie sounds created by loud amplification, reverb, and such tricks as sliding ball bearings up and down guitar strings. In 1966, they began to pick up a following in the London underground; onstage, they began to incorporate light shows to add to the psychedelic effect. Most importantly, Syd Barrett began to compose pop-psychedelic gems that combined unusual psychedelic arrangements with catchy melodies and incisive lyrics that viewed the world with a sense of poetic, child-like wonder. The group landed a recording contract with EMI in early 1967 and made the Top 20 with a brilliant debut single, Arnold Layne, a sympathetic, comic song about a transvestite. The follow-up, the kaleidoscopic See Emily Play, made the Top Ten. Their debut album, The Piper at the Gates of Dawn, also released in 1967, may have been the greatest British psychedelic album ever. Dominated almost wholly by Barrett's songs, the album was a charming funhouse of driving, mysterious rockers, odd character sketches, childhood flashbacks, and freaky pieces with lengthy instrumental passages that mapped out their fascination with space travel. The record was not only like no other at the time; it was like no other that Pink Floyd would make, colored as it was by a vision that was far more humorous, pop-friendly, and light-hearted than those of their subsequent epics. The reason Pink Floyd never made a similar album was that Piper was the only one to be recorded under Barrett's leadership. Around mid-1967, the prodigy began showing increasingly alarm signs of mental instability. Syd would go catatonic onstage; playing music that had little to do with the material, or not playing at all. An American tour had to be cut short when he was barely able to function at all, let alone play the pop star game. Dependent upon Barrett for most of their vision and material, the rest of the group was finding him impossible to work with, in concert or in the studio. Around the beginning of 1968, guitarist Dave Gilmour, a friend of the band who was also from Cambridge, was brought in as a fifth member. The idea was that Gilmour would enable the Floyd to continue as a live outfit; Barrett would still be able to write and contribute to the records. That couldn't work

Biography of Chandragupta Maurya, Indian Emperor

Biography of Chandragupta Maurya, Indian Emperor Chandragupta Maurya (c. 340–c. 297 BCE) was an Indian emperor who founded the Maurya Empire, which rapidly expanded across much of India into modern-day Pakistan. Maurya did battle with Alexander the Great, who invaded the Indian kingdom in 326 BCE, and prevented the Macedonian king from conquering the far side of the Ganges. Maurya went on to unite almost all of what is now India and defeat Alexanders successors. Fast Facts: Chandragupta Maurya Known For: Maurya united ancient India under the Maurya Empire in 322 BCE.Born: c. 340 BCEDied: 297 BCE in Shravanabelagola, Maurya EmpireSpouse: DurdharaChildren: Bindusara Early Life Chandragupta Maurya was reportedly born in Patna (in the modern-day Bihar state of India) sometime around 340 BCE. Scholars are uncertain of some details about his life. For example, some texts claim that both of Chandragupta’s parents were of the Kshatriya (warrior or prince) caste, while others state that his father was a king and his mother a maid from the lowly Shudra (servant) caste. It seems likely that Maurys father was Prince Sarvarthasiddhi of the Nanda Kingdom.  Chandragupta’s grandson, Ashoka the Great, later claimed a blood relationship to Siddhartha Gautama, the Buddha, but this claim is unsubstantiated. We know almost nothing about Chandragupta Maurya’s childhood and youth before he took on the Nanda Empire, which supports the hypothesis that he was of humble origin- no records about him exist until he founded the Maurya Empire. Maurya Empire Chandragupta was brave and charismatic- a born leader. The young man came to the attention of a famous Brahmin scholar, Chanakya, who bore a grudge against the Nanda. Chanakya began to groom Chandragupta to conquer and rule in the place of the Nanda emperor by teaching him tactics through different Hindu sutras and helping him raise an army. Chandragupta allied himself to the king of a mountain kingdom- perhaps the same Puru who had been defeated but spared by Alexander- and set out to conquer the Nanda. Initially, the upstart’s army was rebuffed, but after a long series of battles Chandragupta’s forces laid siege to the Nanda capital at Pataliputra. In 321 BCE the capital fell, and 20-year-old Chandragupta Maurya started his own kingdom. It was named the Maurya Empire. Chandragupta’s new empire stretched from what is now Afghanistan  in the west to Myanmar (Burma) in the east, and from Jammu and Kashmir in the north to the Deccan Plateau in the south. Chanakya served as the equivalent of a prime minister in the fledgling government. When Alexander the Great died in 323 BCE, his generals divided up his empire into satrapies  so that each of them would have a territory to rule, but by about 316, Chandragupta Maurya was able to defeat and incorporate all of the satrapies in the mountains of Central Asia, extending his empire to the edge of what is now Iran, Tajikistan, and Kyrgyzstan. Some sources allege that Chandragupta Maurya may have arranged for the assassination of two of the Macedonian satraps: Philip, son of Machatas, and Nicanor of Parthia. If so, it was a very precocious act even for Chandragupta- Philip was assassinated in 326  when the future ruler of the Maurya Empire was still an anonymous teenager. Conflicts With Southern India and Persia In 305 BCE, Chandragupta decided to expand his empire into eastern Persia. At the time, Persia was ruled by Seleucus I Nicator, founder of the Seleucid Empire, and a former general under Alexander. Chandragupta seized a large area in eastern Persia. As part of the peace treaty that ended this war, Chandragupta gained control of that land as well as the hand of one of Seleucus’s daughters in marriage. In exchange, Seleucus received 500 war elephants, which he put to good use at the Battle of Ipsus in 301. With as much territory as he could comfortably rule to the north and west, Chandragupta Maurya next turned his attention to the south. With an army of 400,000 (according to Strabo) or 600,000 (according to Pliny the Elder), Chandragupta conquered all of the Indian subcontinent except for Kalinga (now Odisha) on the east coast and the Tamil kingdom at the southern tip of the landmass. By the end of his reign, Chandragupta Maurya had unified almost all of the Indian subcontinent. His grandson Ashoka would go on to add Kalinga and the Tamils to the empire. Family Life The only one of Chandragupta’s queens or consorts for whom we have a name is Durdhara, the mother of his first son Bindusara. However, it is believed that Chandragupta had many more consorts. According to legend, Prime Minister Chanakya was concerned that Chandragupta might be poisoned by his enemies, and therefore  started introducing small amounts of poison into the emperor’s food in order to build up a tolerance. Chandragupta was unaware of this plan and shared some of his food with his wife Durdhara when she was pregnant with their first son. Durdhara died, but Chanakya rushed in and performed an emergency operation to remove the full-term baby. The infant Bindusara survived, but a bit of his mother’s poisoned blood touched his forehead, leaving a blue bindu- the spot that inspired his name. Little is known about Chandragupta’s other wives and children. Chandraguptas son Bindusara is likely remembered more because of his son than for his own reign. He was the father of one of India’s greatest monarchs, Ashoka the Great. Death When he was in his 50s, Chandragupta became fascinated with Jainism, an extremely ascetic belief system. His guru was the Jain saint Bhadrabahu. In 298 BCE, the emperor renounced his rule, handing over power to his son Bindusara. He then  traveled south to a cave at Shravanabelogola, now in Karnataka. There, Chandragupta meditated without eating or drinking for five weeks until he died of starvation in a practice known as sallekhana or santhara. Legacy The dynasty that Chandragupta founded would rule over India and the southern part of Central Asia until 185 BCE. Chandraguptas grandson Ashoka would follow in his footsteps in several ways- conquering territory as a young man and then becoming devoutly religious as he aged. In fact, Ashokas reign in India may be the purest expression of Buddhism in any government in history. Today, Chandragupta is remembered as the unifier of India, like Qin Shihuangdi in China, but far less bloodthirsty. Despite a paucity of records, Chandragupta’s life story has inspired novels, movies such as 1958s â€Å"Samrat Chandragupt,† and even a 2011 Hindi-language TV series. Sources Goyal, S.

What Is So Important About Jerusalem Essay Example | Topics and Well Written Essays - 1500 words

What Is So Important About Jerusalem - Essay Example At the beginning of the twentieth century, British forces captured Jerusalem from the Turks. Following this capture, the British troops pledged that they would conserve all religious sites and places of worship in the holy city. In the same era, Chaim Weizmann, a Zionist purchased the area surrounding the wall in order to make it accessible to other Jews. This event shows that the Jews were willing and able to sacrifice their wealth in order to gain access to the western wall. Christianity: Church of the Holy Sepulchre is an ancient church in Old City of Jerusalem. The church is believed to be the site of Jesus’ burial and resurrection. The church has an extensive history that stretches all the way from the 4 century AD. Currently, the church serves as the control center for Greek Orthodox Patriarch of Jerusalem. The control of the church and adjacent land is under the control of several Christian churches around the world. The church is believed to be the center of key phenom enon and sites in the Christian faith that include Golgotha, the hill of Calvary, and the original cross of Jesus. The church is of immense significance to Christian of all ages. Being the main Christian establishment in the holy land, the Church of the Holy Sepulcher is of interest to many world leaders. Moreover, the church was the target of crusaders who travelled from Europe to the holy land6. The church was an important symbol in ancient early civilization and it was destroyed and reconstructed many times. For example, the churchy was demolished by the Persians in 614 AD under the command Khosrau II. The church underwent numerous demolitions and reconstructions under various authorities. In the 7th century, the Persians invaded Jerusalem and removed the Cross-from Church of the Holy...Recent archeological evidence has revealed that the wall was not completed during Herod’s reign. The studies have revealed that constructions may have been completed at the end of the seven the century. The wall and the temple courtyard that it encloses have been a pilgrimage site for the Jews over the centuries. Since the establishment of the Zionist movement, the wall has been a major cause of conflict between Jews and Muslims3. Both the Muslims and the Jews claim right of ownership including the right to worship and pilgrimage to the wall and the temple. Indeed the wall is a fundamental aspect of the Jewish religion. According to the Jews, King Solomon constructed the western wall and it serves as the only remnant of the first temple. The Jews regard the wall as the only accessible spot of the holy land. The site is the closest to even ha-shetiya (the foundation stone) located in the temple mountain4. The foundation stone is regarded ans the holy of holies and no one is allowed to set foot upon it. The Jews used to pray by the walls during the time of tribulation and it is believed that God heard their prayers. Through the ages, Jews of all age gathered and prayed beside the western wall.Certainly, there are many unknown facts about the holy lands and their significance to the future of humanity. Therefore, modern religions cannot be based on these holy lands.

Change Model Essay Example for Free

Change Model Essay The aim of this essay is to critically analyse the background of the Qantas and its decision to launch Jetstar on May 2004 that operated around 800 flights a week across network of 14 destinations within Melbourne, Sydney and Brisbane. Secondly, this essay will evaluate how Data Collection Feedback Cycle change model is used to gather major information and to critically analyse it. Thirdly, this essay will critically evaluate the background of Qantas and Virgin Blue and will also highlight various reasons that eventually led the Qantas group for the launch of the Jetstar. Fourthly, this essay will also critically analyse the revenue and profit performance of Qantas prior the introduction of Jetstar i.e. 2002. Fifthly, it will continue to critically evaluate the trend in Qantas and Virgin Blue in 2003. Then the sixth paragraph will also critically evaluate the trend in Qantas after the launch of Jetstar. Lastly, the essay will also look into the annual reports of the year 2005-2009 and critically analyse the significant value added by the Jetstar to the Qantas group; and will critically analyse whether the executive decision of Qantas to launch Jetstar in order to retain the 60% domestic aviation market from its competitors has been a strategic success or not. This paragraph will critically analyse the change management information gathered to launch Jetstar low cost airline in May 2004 by using the Data Collection Feedback Cycle change model. Nadler (1977) as cited in Cumming and Worley (2009:122) highlights that the Data Collection Feedback model consists of five phases that are (1) planning to collect data, (2) collecting data, (3) analysing data, (4) feeding back data and (5) following up on the data collected. In planning to Gather information to justify change Nadler (1977) argues that primary methods such as, direct interviews with CEO and key change agents, observing and identifying the need for change and the use of un obstructive measure as sampling technique, force field analysis and scatter diagrams, could be used to gather major information. In contrast Danaher have used various published data to trace the evolution of the Jetstar strategy of its initial position, to its efforts to attain price competitiveness and service parity, followed by its highly focused, cost-effective service delivery strategy. Based on it they have developed a hierarchical model with parameters estimated at the  individual level. This allows us to study not only how service design and pricing initiatives shift the perceived performance of Jetstar relative to its competitors but also how the airline can move market preferences toward areas in which it has competitive advantage. After done with the planning of the collection of data from competitors performance on its revenue, sales profits, passenger numbers and market share in 2002, 2003 and 2004 against Qantas key performance indicators for the same period between 2002, 2003 and 2004 from the Annual Reports of both Virgin Blue and Qantas domestic operations. Nadler (1977), after the data has been collected data they are analysed using the qualitative change data such as directors report, World Business Briefing /Australia: Airline Profit(2004).The reminder of this essay will critically analyse the data collected from secondary sources such as Annual Reports, newspaper articles and journal articles to analysis the data sourced to evaluate what would be the most effective change to be implemented by Qantas in responding to Virgin Blue competition the Australian aviation domestic sectors. This paragraph will evaluate the basic background of Qantas and Virgin Blue and will also highlight various reasons that eventually led the Qantas group for the launch of the Jetstar. After the deregulation of Australian aviation market there were several airline companies entering the market however the most significant entrance was of low fare airlines Impulse in June and Virgin Blue in August 2000. The arrival of Impulse Airlines and Virgin Blue doubled the number of players and dramatically challenged the stable duopoly of Qantas (after its merger with Australian Airlines) and Ansett, setting off a vicious price war (Traca, D., 2004). However, Impulse facing a major trouble in the cash flow agreed on May 1, 2001 to hand over its operations to its biggest rival, Qantas Airways. As per the deal Impulse stopped its passenger service under its own name on May 14 and leased 21 aircraft as well as cabin crews and pilots to Qantas. The deal led the stock of Qantas heaved by 26% closing at $3.40 per share giving Qantas a significantly stronger position in the Australian market (Gaylord, 2001). Qantas, Australia’s leading domestic and international carries launched a budget airline called Jetstar in May 2004 (Qantas annual report, 2004). With Jetstar Qantas’s aim was to cover the low fare segment of the aviation  industry, which came into existence in the year 2000 with its competitor, Virgin Blue. Virgin had been successfully eating up QANTAS market share by attacking it from below as a no frills provider. In 2001 the collapse of Ansett in domestic market, led Qantas to lease extra flights, add hundreds of special flights in order to help stranded travellers due to Ansett crisis. At the time Qantas flew more than 50,000 former Ansett passengers for free and other 65,000 on heavily discounted fares. Due to this Qantas was able to deliver a profit before tax of $631m and net profit after tax of $428 million at the end of 2002, 30 June, despite of the fact that the world’s aviation market was suffering from â€Å"constant shock syndrome†, due to the September 11 attack followed by bombings in Bali, the war in Iraq and of course the devastating outbreak of Severe Acute Respiratory Syndrome (Qantas annual report, 2003). The shutdown of Ansett also highly benefitted Virgin Blue, since the event provided a wide opportunity for Virgin Blue to grow rapidly and become Australia’s second leading domestic carrier. In 2000 it started with only one route (Brisbane to Sydney) with two aircrafts and a team of just 200 people. In 2001, with the opportunity to widen its market segment, 14 new routes were launched (virginaustralia – history). The aim of this paragraph is to highlight how Qantas and Virgin Blue became the only two players in the Australian domestic aviation market in 2002. It will also look in to the key financial indicators of both the companies so that a comparison could be drawn out. In 2002 there were only two companies that survived the fare war of 2000-2001. One of them was Qantas that gained 80% of the domestic market share following Ansetts cessation. Whereas, the number of international passenger declined by 11% which makes an average decline of about 25% in global aviation market (Traca, D., 2004). In the same year Qantas domestic carried 1485 million passengers making a RPK of $2034 million and the ASK of $2503 million (Traffic and capacity statistics, 2002). Qantas announced its financial results for the year ended 30th June 2002. As per the financial result the company had $631 million of profit before tax, a net profit after tax of $million, revenue of $ 10,968.8 million and earnings per share of 29.1 cents (Qantas annual report, 2002). The other survivor of the fare war, Virgin Blue managed to emerge as second Australian Domestic carrier, covering of about 20% of the domestic market  (Traca, D., 2004). Due to its strategic low operating cost and soaring market share, it was able to achieve net profit before tax of $34.8 million and revenue of $388.3 million. In this year the airline carried 3.2 million passengers, its traffic as measured by RPK’S was 3169 million, capacity measured by ASK’S was 3898 million (Virgin Blue annual report, 2004). In March 2002 Patrick Corporation, the premier port cargo handler, bought 50% of the airline. This change made Godfrey, chief executive of Virgin Blue confident about the enlargeme nt of the domestic operation and also expansion into the international market with service to South Pacific (Traca, D., 2004). This paragraph critically analyses the key financial indicators of the Qantas and the Virgin Blue of the year 2003. It will also highlight how Virgin Blue concentrating only of the leisure domestic market was slowly overcoming the market share of Qantas. In 2003 Qantas domestic carried 1768 million passengers making a RPK of $2262 million and the ASK of $2683 million (Traffic and capacity statistics, 2003). Qantas announced its financial results for the year ended 30th June 2003. As per the financial result the company had $502.3 million of profit before tax, a net profit after tax of $343.5 million, revenue of $11,374.9 million and earnings per share of 20 cents (Qantas annual report 2003). Speaking of announcements, in the Annual General Meeting held on 16th October 2003 it was announced that â€Å"the airline is investigating the establishment of separate domestic low cost airline to service the leisure market in Australia† (Preliminary monthly traffic and capacity statistics, July 2003).In this same year Virgin Blue carried 6.8 million passengers, its traffic as measured by RPK’S was 7194 million, capacity measured by ASK’S was 9078 million. Taking advantage of the fact that Virgin Blue had no other competitor serving the price sensitive market of Australia, it earned revenue of $914.6 million, compared to previous year the revenue earned up roared by 135.5% and the number of passengers carried also increased by 107% (Virgin Blue annual report, 2003). This paragraph will critically analyse the launch of Jetstar in May 2004 and the changes that it brought in the key financial indicators of Qantas and as well as of Virgin Blue. Following the announcement made in 2003 Annual  General Meeting Qantas Introduced Jetstar in May 2004. In the first year Jetstar alone carried 273,000 passengers. Prior Jetstar Qantas already had Qantas Domestic and Qantas Link serving domestic passengers. With these three Qantas in total carried 1973 million passengers. Compared to 2003/04 the number increased by 9.4% (Traffic and capacity statistics, 2004). In the same year Total Domestic (Qantas, Qantas Link and Jetstar) traffic was measured in Revenue Passenger Kilometres (RPKs) of $2451 million while capacity, measured in Available Seat Kilometres (ASKs) increased to $3021 million (Traffic and capacity statistics, 2004). On 19 August 2004, Qantas announced its financial results for the year ended 30 June 2004. In the announcement it was stated that the company had achieved a profit before tax of $964.6 million and a net profit after tax of $648.4 million. Similarly, $11.4 billion of revenue, earning per share of 35.7 cents (Qantas annual report, 2004/05). Despite increasing domestic competition during the year Virgin Blue continued to show strong growth and profitability. During the year Virgin Blue carried over 10million (m) passengers, an increase of 53% compared to previous year. Doubling its passenger number the third time in a row in this same year it welcomed its 20 millionth passenger. Its revenue for the 2004 financial year was $1362.3million which is 49% more than the previous year. In the same year profit before tax was up by 45% to 226.2million and a Net Profit After Tax of 158.5million (Virgin blue annual report, 2004). Till March 31, 2004 Virgin Blue had 44 Boeing Net Generation 737 – 700 737 -800 aircraft out of which 36 were leased and 8 were owned. However, during the year the fleet was increased by 15 aircrafts. Since the day of establishment Virgin Blue was committed to keep its cost base low and they are continuously working through it so that they could consistently provide their customers with low fares travel. Their cost per ASK for the financial year 2004 was 8.16 cents whereas a year before it was 8.48 cents. A decrease of 3.5% put the company on a good front in terms of scale and productivity (Virgin blue annual report 2004). The Australian discount airline Virgin Blue, has won 30% of the market from Qantas, the national carrier, which will introduce a low-fare airline, Jetstar. Fare surcharges are being imposed by both groups as fuel pri ces rise (Shaw, 2004). Jetstars initially offered $48 for Melbourne to Hobart route and from $54 for Sydney to the resorts south of Brisbane. The price was similar  to what the price Virgin Blue was offering at the same period. All Jetstar flights offered one class of travel, with unreserved seating. In contrast Virgin Blue offered assigned seating and baggage connections to final destinations (Henly, 2004). This paragraph critically analyse the key indicators for Qantas and Virgin Blue for launching Jetstar in May 2004. It is very clear with the annual report that Jetstar has been profitable ever since it was launched in the year 2004 (Jetstar Media centre). However, the road wasn’t quiet smooth in the initial years. From its launch Jetstar was exclusively using a â€Å"low price† message in its communication, but it was lagging way behind Virgin Blue in terms of quality. The Jetstar overall quality disadvantage was greater at 22.3% (6.02 versus 7.75) (Danaher et.al, 2011. pp. 586 -594, Fig 3). Jetstar was already appealing on the price front, and then it addressed its deficit in quality and tackled that by focusing on some specific sub attributes (not disclosed by the company) that provided Jetstar a good opportunity to overcome the point of difference with Virgin Blue. Then the price perception of Jetstar relative to Virgin Blue dramatically improved from 6.9% deficit in March 2008 to 2.5% deficit in only 3months i.e. 7.42 versus 7.62 (Danaher et.al, 2011. pp. 586 -594, Fig 3). Since the establishment the main concern as a parent company for Qantas Group was that whether Jetstar would financially be profitable in its own right. Hence, it did by earning revenue of $1.020 billion, $1.414 billion, and $1.605 billion in the year 2007, 2008, and 2009 respectively. It was 7%, 10%, 12% of Qantas group revenue respectively (Qantas annual report, 2009). Similarly, in the same order the profit earned was $79 million, $104 million and $118 million (Danaher et.al, 2011. pp. 586 -594, Table 2). Similarly, speaking of market share of Jetstar, it has increased by 29% from the year 2008-2009. Earlier with the perceived mediocre price competitiveness and low quality it was in a poor position as compared to Virgin Blue, whereas, with the necessary remedies taken within the 1st quarter of 2008 it was in position almost equal to Virgin Blue in terms of covering the large proportion of the target market. Jetstar Market Share of Domestic Australian Leisure Air Travel was 14% in the first quarter of 2008, with the changes made the market share increased to 14.6% and it gradually kept on increasing and it had 18.1% of market share in March 2009. Further, with the increase in profit it improved its perceptual position, whereas,  Virgin Blue has remained relativ ely stationary. In conclusion if we are to pay close attention to the domestic growth strategies of the country’s largest airline company; Qantas, its decision of launching Jetstar seems be a successful strategic decision. It was matter of concern that the Virgin Blue an airline company focusing on the price sensitive market would whether survive the competition with 82 year old veteran airline company. However, with its striking approach of low fare Virgin Blue today covers 35% market share of the domestic aviation sector. By critically evaluating the financial indicators of both companies for the year 2002-2004 and also following the series of events, it becomes quiet clear that though Virgin Blue had started small it managed to cover 20% of the target market in 2002. In further years concentrating only in the no frill travel it was able to hold the 30% of the market share, which became a matter of concern for Qantas because though it was making more profits then Virgin Blue it was losing it domestic market grip, therefore, led to the launch of Jetstar. However, even after the Launch of Jetstar Qantas performance was not like it was expected because in the year 2004 Qantas domestically carried only 2061 million passengers which were only 88 million more than the last year. However, with the necessary major changes (not disclosed by the company) Jetstar alone was able to regain the market share of 18.1% by March 2009. REFERENCE LIST Gaylord, B. (2001).

Ideology in Nathaniel Hawthorne’s The Minister’s Black Veil Essay

Ideology in Nathaniel Hawthorne’s The Minister’s Black Veil Bennett and Royle in their textbook, Introduction to Literature, Criticism and Theory, define ideology as representing â€Å"†¦ ‘the imaginary relationship of individuals to their real conditions of existence’† (161). The ideology of self, of personal identity, is represented by a person’s perception of what is acceptable in their society. In Nathaniel Hawthorne’s short story, The Minister’s Black Veil, the minister appears before his community with a black veil covering his face. He gives no explanation for this apparel and the community becomes agitated that their minister refuses to remove it. The readers challenge is to discover why the minister wears the veil and why he won’t take it off. Hawthorne challenges the readers ideology of self with his choice of words, by showing how ideology is redefined by each subject, and by using as his form the technique of the parable. The parishioners expectations are shattered by the appearance of their beloved minister wearing a black veil over his face. Children, with bright faces, tripped merrily beside their parents, or mimicked in graver gait, in the conscious dignity of their Sunday clothes. Spruce bachelors looked sidelong at the pretty maidens, and fancied that the Sabbath sunshine made them prettier than on weekdays (Hawthorne 1) These expectations are portrayed by the way the story begins. Hawthorne uses words that suggest happiness; â€Å"bright† â€Å"merrily† â€Å"pretty† â€Å"fancied† and â€Å"sunshine†. But this ‘happiness’ vanishes with the appearance of the minister. The expectations of what is socially acceptable are challenged by the appearance of the black veil. â€Å"But what has good Parson Hooper got upon his face?† c... ...o understand the parable. A parable is used to explain something that is unexplainable and cannot be explained if the reader does not understand it. The reader is in constant danger throughout the reading of having his ideology of self shattered by the very real possibility that he won’t ‘get it’. The entire story is as obscure and shaky as ideology itself. Hawthorne’s choice of words throughout the story set up the reader for a continual bombardment of his/her ideology of self and societal expectations. Works Cited Bennett, Andrew and Nicholas Royle.

Buisiness law

What must a plaintiff, in a negligence case, prove and establish in order to recover? What are some of the common defenses available to defendants in negligence suits? Provide an example of a negligence case with one of the common defenses. Negligence is a mode of committing certain torts like negligently or carelessly committing trespass, nuisance or defamation. It can be defined as the conduct which creates a risk of causing damage, rather than a state of mind. In an action for negligence and recover the plaintiff has to prove the following essentials.That the defendant owed duty of care to the plaintiff 2. The defendant made a breach of that duty . Plaintiff suffered damage as a consequence thereof. But it is to be remembered that the burden of proof of negligence always lies on the plaintiff. (Res Ipsa Loquitur) The defendants can plead defenses to reduce or eliminate his liability. Such defenses are contributory negligence, comparative negligence, and assumption of risk. In cont ributory negligence the negligence of the plaintiff is also contributing cause of her injury and is barred from recovering from a negligent defendant.In Harris Vs Toronto Transit Commission (1968) the Supreme Court Canada held that if a boy sitting in a bus projected his arm outside the bus in spite of warning and is injured, he is guilty of contributory negligence. A comparative negligence is a type of partial defense in which there is a reduce in the amount of damages that a plaintiff can recover in a negligence-based claim based upon the degree to which the plaintiff's own negligence contributed to cause the damages.The assumption of risk denotes that the plaintiff himself knew that his activity was dangerous and thus bears all responsibility for any injury that resulted. ************************************************ References 1.

Transport of Solute in Solvent through Osmosis Essay

Objective: The objective is to simulate passive transport: diffusion of solutes and osmosis of water through a semipermeable membrane (dialysis tubing). The experiment will show how molecules in solution move from areas of higher concentration to areas of lower concentration in the attempt to reach homeostasis in different circumstances. Introduction: The main purpose of this lab was to observe diffusion and osmosis. This is demonstrated using dialysis tubing and a combination of monosaccharaides, disaccharides, water (H20), and sodium chlorine (NaCl), also known as table salt. We then calculated the percent change of mass over a period of time. Due to kinetic energy, cells tend to bump into one another; this is the result of the process called diffusion. Diffusion is the movement of molecules from a place of higher concentration to a place of lower concentration. In this lab, diffusion causes a physical change of our cells (mass). Osmosis is a type of diffusion that involves water. Osmosis occurs when water moves through a semi-permeable membrane. The water moves from a place of higher water concentration to a place of lower water concentration. Water potential measures free energy of water in any solution. A solution is a liquid mixture of two or more components. This mixture consists of a minor component (the solute) which is c onsistently distributed within a major component (the solvent). Water potential consists of 2 parts: osmotic potential and pressure potential. Osmotic potential pertains to the water molecules that move from a hypotonic solution to a hypertonic solution (changing the concentration gradient), while pressure potential pertains to the exertion of pressure the cell is under. The pressure is caused by the height of water exposed to the atmosphere above the artificial cell. The concentration gradient is generally the difference in concentration of a dissolved substance in a solution. This occurs between a region of high density and lower density. Water potential of distilled water in  atmospheric pressure is 0, because the osmotic and pressure potentials are 0. For example, in plant cells, osmotic potential is lowered because more of its solute is being dissolved in the cytoplasm. When placed in pure water, the cells of the plant are hypertonic. This means the plant cells have more osmo tic concentration. The water potential within the beaker is higher making it hypotonic, meaning it has a lower osmotic pressure. Therefore the water will move into the cell because water moves from hypotonic environments to hypertonic environments. This results in a swelling cell. On the contrary, if solute is added to the beaker, the water potential in the cell will be greater, resulting in a hypotonic cell. Therefore water will move out of the cell, causing it to shrivel. This is relative to this lab. However, not all solutions are like this. Solutions that have reached the state of equilibrium are isotonic. This means that both solute and solvent have the same osmotic pressure. The rates of the reaction are determined by the molecular size of the particles. If the particles or smaller, they diffuse through the semi-permeable membrane much faster than particles larger than the semi-permeable membrane. This is because the smaller particles have less of a resistance to pass through the selectively permeable membrane. If the particle is larger it is going to take a much longer time for the particle to push its way through the membrane. Materials: Dialysis tubing Scissors Small funnel Graduated cylinder Paper towel Digital scale 400mL beaker 250mL beaker 1 mL pipette Test tube Hot plate Weigh boats Pipette Pipetter Methods: 1) Obtain ten 40 centimeter strips of dialysis tubing and soaked them in water. This will moisten the dialysis tubing to a rubbery texture that is easier to maneuver and work with. Tie off one end of the tubing 2cm from the end to form a bag. Finally to open the other end of the bag, we rubbed the closed, untied end between our fingers until the edges separated. 2) Measure 25mL of the applicable solution needed for the dialysis cell. This should be done with a 25mL graduated cylinder. Measuring with a 25mL graduated cylinder insures that no errors be made. To properly measure 25mL, the graduated cylinder should be placed on a flat surface and you should be at eye level with its measurements. A full 25mL is measured at the bottom of the meniscus. Once the solution has been measured, using a small funnel, pour the solution into the dialysis bag by inserting the tip of the funnel into the open end. Finally make a note of what the cell is containing; it is very easy to get them mixed up. A source of error that is unwanted. 3) Tie the open end of the dialysis bag 2cm from the end of the bag. 4) Rinse the dialysis cell thoroughly under water to guarantee any foreign substance that may have touched the dialysis cell is rinsed off and gently blot the dialysis cell with paper towel. The dialysis cells must be completely dry so when the cell is being weighed, the digital scale will not be weighing water weight on the cell as well. Using a weigh boat, measure the cells mass. The weigh boat is used for the purpose to avoid cross contamination between the cell and scale. To insure that the cell is the only thing being weighed, place the weigh boat on the scale and press clear. This will set the scale to 0 with the weigh boat still on it. Place the cell on the weigh boat and record the total weight of the cell. Your data should be weighed in grams (g). Before submerging your cell in its beaker with solution correlated on Table #1, the dialysis cell must be weighed. This will give us an idea of what the cell begins at and in what way diffusion and osmosis affects the dialysis cell . The cell must be weighed every 30 minutes in a time period of 90 minutes. The dialysis cell should be weighed four times. 5) Submerge each prepared dialysis cell in a 400mL beaker with 150 mL’s solution correlating to Table #1. These solutions must be measured using a 100 mL graduated  cylinder. Measuring with a 100mL graduated cylinder ensures that no errors be made. To properly measure 100mL, the graduated cylinder should be placed on a flat surface and you should be at eye level with its measurements. A full 100mL is measured at the bottom of the meniscus. Because 150mL of the solution is needed, two separate measurements must be made. An entire measurement from the 100mL graduated cylinder and a half should be measured. Record the time the dialysis cell is submerged in the solution; this will insure an accurate timing at which the dialysis cell must be weighed. Label each dialysis cell and solution filled beaker. This will provide knowledge as to which solution is contained in each beaker and avoid any error from being made. 6) In 30 minute intervals for 90 minutes, the cells must be removed from each beaker and blotted try with clean paper towel to be weighed. Record each measurement every time the cell is being weighed. Do not rinse the cell under water again; this may compromise the cell and solution within the beaker. 7) At the conclusive part of the cell (last time weighing the cell) remove the cell from the solution filled beaker, and blot it dry. Proceed to using scissors to cut the cell, and pour the remaining content into a 250mL beaker. Label each beaker as to which it is containing. 8) Using 3 clean test tubes perform a chloride (Cl-) test, a glucose test and a sucrose/lactose test. Obtain 2mL of each solution from each beaker. This is done using a pipette and pipette. Place the tip of the pipette in the solution of the beaker, and the pipetter is placed at the other end of the pipette. The pippetter sucks the solution into the pipette, this is a better method then using ones mouth to suck up the solution because it is more accurate and safer. Using a hot plate and a beaker filled with water, place each finished test tube into the beaker. The water contained in the beaker must be boiling before each test tube is placed within it. Using this method, the solutions reaction will occur at a much faster rate. This applies to each test. In the (Cl-) test, 2 drops silver nitrate(AgNo3) are added to each 2mL solution that has been measured and placed into a test tube from the obtained material from the cell. This test measures for the salt content in the solution. In th e glucose test, Benedict’s test is performed using a 1:1 ratio of Benedict’s test to solution. These tests for the glucose in each solution. Finally the sucrose/lactose test uses the same content as the glucose test. Benedict’s test is performed using a 1:1 ratio  of Benedict’s test to solution. This test measures for reducing sugars. The indicator for each test is color. When there is a color change to the solution that means the test has tested positive. 9) At the end of the lab, all observations should have been recorded in your notebook. Results: The data shows (Graph #1 and Graph #2) that in each case, the dialysis bag slight increases or decreases in mass over a period of 90 minutes. The increase or decrease in mass of the dialysis cell is solely based upon the concentration gradient within the dialysis cell and its environment as to which it is placed in. In each graph, it displays which dialysis cells have increased or decreased in mass. For each cell that has increased in mass, (A1, B1, C1, D1, E1, and F1), diffusion and osmosis has occurred into the cell. As a result the cell has swollen because water has moved into the cell. Dialysis cells that have decreased in mass, (A2, B2, C2, D2, E2, and F2), have had the opposite reaction occur. Diffusion and osmosis has moved water out of the cell, causing a decrease in mass. This is due to the dialysis cell containing a hypotonic solution as its environment at which it was submerged is hypertonic. This then causes the cell to shrink in mass. Due to the different data shown in G raph #1 and Graph #2, we know that the cells and environments contained different concentration gradients because not all data is the same. This means that no dialysis cells or environments have reached equilibrium and have become isotonic. Discussion: The purpose of this lab was to observe the physical mechanisms of osmosis and diffusion. Diffusion is the movement of particles. The particles move from areas of higher concentration to an area of lower concentration. The diffusion of water moves into or out of a selectively permeable membrane, this process is called osmosis. Because of the selectively permeable membrane, nothing but water and other very small particles are able to diffuse. The dialysis tubing is similar to the function of the cell membrane. As a result the dialysis cell loses water and also gains because of osmosis due to the transport of water. This occurs when the dialysis cell is placed in an environment in which water concentration is greater than  that of the cell. The dialysis cell gains water when placed in and environment in which the concentration is lower. This concept describes how molar concentration (the number of moles in a solute per liter of solution) affects diffusion. The perception of solutions diffusing has been observed in different situations. Diffusion always moves from a high concentration to a low concentration, this is affected by molar concentration. As the molecular mass decreases, more solution is diffused. This hypothesis was made due to the knowledge of molecules diffusing down a concentration gradient. As a result, the mass of the dialysis tubes have increased, as the molarity of a solution increases, the percent of change in mass will increase as well. This affect occurred in cells (A1, B1, C1, D1, E1, F1). As the molarity of a solution decreased in other dialysis tubes, the mass of the dialysis tubes have decreased and percent change in mass has decreased as well. The amount of increase and decrease of diffusion is based on the molecule size. This occurred in cells (A2, B2, C2, D2, E2, F2). As molecular size increases, the rate of diffusion decreases. This is because it has a greater resistance going through the medium of the membrane. When molecular size de creases, then rate of diffusion increases because the molecule has less of a resistance to go through the dialysis cells semi-membrane.

Without having any group effort within the class, the lab would have taken more time then what would have been given. I would also like to thank the class for contributing in providing portions of the lab data, without this data we would have not been able to properly provide right information need for the lab.

This helps us to understand the concentration gradients of the cell or environment of the cell due to its reaction. The cells that increases in size, we now know that the cell was hypertonic placed in a hypotonic solution because in order to reach equilibrium the amount of particles within the cell must be the same. Because they have not reached equilibrium this results in the movement of molecules moving from a hypotonic solution to a hypertonic solution through a selectively permeable membrane (dialysis tubing), this is called osmosis. In order for the particles to move across the membrane diffusion must occur for the movement from high osmotic concentration to lower osmotic concentration to occur. The cells that decrease in mass are hypotonic place in a hypertonic solution. We know that because osmosis and diffusion has occurred, allowing the solution and pa rticles to move out of the cell into the cells environment. Once the cell is finished being weighed in 30 minute intervals over a period of 90 minutes, a silver nitrate (AgNO3) test (test for salts present in the solution), glucose test a sucrose/ lactose test (tests for reducing sugars) are conducted. The column in green represents whether the solutions tested positive or negative for the substances.

Due to some cells having gained or lost more than other cells, some of the differences were much greater or lower than others. These means diffusion would have occurred faster or slower do to the solutions molecular size. When a particle is bigger, it takes a longer time for it to diffuse through the membrane because it has to push itself through the membrane rather than slide through the membrane as a small particle would.

Sources of Error: Forgetting to rinse our dialysis bags with water before weighing our cell will cause cross contamination to occur thus changing the composition of the solution that the cell has been submerged in as well as affecting the rate of diffusion and osmosis due to the dialysis tubing pores having already been compromised.

History of the Integrated Circuit (Microchip)

History of the Integrated Circuit (Microchip) It seems that the integrated circuit was destined to be invented. Two separate inventors, unaware of each others activities, invented almost identical integrated circuits or ICs at nearly the same time. Jack Kilby, an engineer with a background in ceramic-based silk screen circuit boards and transistor-based hearing aids, started working for  Texas Instruments  in 1958. A year earlier, research engineer  Robert Noyce  had co-founded the Fairchild Semiconductor Corporation. From 1958 to 1959, both electrical engineers were working on an answer to the same dilemma: how to make more of less. What we didnt realize then was that the integrated circuit would reduce the cost of electronic functions by a factor of a million to one, nothing had ever done that for anything before - Jack Kilby Why the Integrated Circuit Was Needed In designing a complex electronic machine like a computer it was always necessary to increase the number of components involved in order to make technical advances. The monolithic (formed from a single crystal) integrated circuit placed the previously separated transistors, resistors, capacitors and all the connecting wiring onto a single crystal (or chip) made of semiconductor material. Kilby used germanium and Noyce used silicon for the semiconductor material. Patents for the Integrated Circuit In 1959 both parties applied for patents. Jack Kilby and Texas Instruments received U.S. patent #3,138,743 for miniaturized electronic circuits. Robert Noyce and the Fairchild Semiconductor Corporation received U.S. patent #2,981,877 for a silicon-based integrated circuit. The two companies wisely decided to cross-license their technologies after several years of legal battles, creating a global market now worth about $1 trillion a year. Commercial Release In 1961 the first commercially available integrated circuits came from the Fairchild Semiconductor Corporation. All computers then started to be made using chips instead of the individual transistors and their accompanying parts. Texas Instruments first used the chips in Air Force computers and the Minuteman Missile in 1962. They later used the chips to produce the first electronic portable calculators. The original IC had only one transistor, three resistors, and one capacitor and was the size of an adults pinkie finger. Today an IC smaller than a penny can hold 125 million transistors. Jack Kilby holds patents on over sixty inventions and is also well known as the inventor of the portable calculator (1967). In 1970 he was awarded the National Medal of Science. Robert Noyce, with sixteen patents to his name, founded Intel, the company responsible for the invention of the microprocessor, in 1968. But for both men, the invention of the integrated circuit stands historically as one of the most important innovations of mankind. Almost all modern products use chip technology.

An explanation of various marketing terms

An explanation of various marketing terms is the use of consumer-direct channels to reach and deliver goods and services to customers without using marketing middlemen.†Direct Marketing† is the use of consumer-direct channels to reach and deliver goods and services to customers without using marketing middlemen. Direct marketing implies marketing to the consumers directly without secondary media such as TV commercials. Direct Marketing includes the distribution of fliers, displaying signs such as â€Å"weekly specials† inside the store. It is used to target customers who cannot resist a good deal or bargain. Some Direct marketers use their customer database to contact them for special offers. They tailor their marketing offers and communications to the needs of individual buyers. Direct Marketing is generally used by small to medium size companies that do not have the budget for expensive commercial. There are many forms of direct marketing. The major types are as follows: Direct mail – the adverti ser contact prospective customers by sending some form of advertisement through the mail. Music and book clubs, magazine clearing house, and credit card companies make use of direct mail. Catalogue marketing – companies mail catalogues to consumers and to businesses or make them available at retail stores, and consumers make their purchase from the catalogues. For example, Sears and Canadian Tire’s catalogue shopping. Catalogue retailers appear well suited to operating on the internet as they has the systems and distribution experience required for such an undertaking. Telemarketing – using the telephone and call centers to sell directly to prospects and existing consumers. Companies use call centers for Inbound (receiving calls from customers) and outbound (initiating calls to prospects and customers) telemarketing. Direct marketing has been a major growth area in retailing. Its advantages related particularly to its ability to direct the marketing effort to th ose consumers who are most likely to respond positively. It also offers products and services in a way that is most convenient for the consumer. 2. _____ consist(s) of a collection of incentive tools, mostly short term, designed to stimulate quicker or greater purchase of particular products or services by consumers or the trade. â€Å"Sales promotions† consist of a collection of incentive tools, mostly short term, designed to stimulate quicker or greater purchase of particular products or services by consumers or the trade. Sales promotion as tools and techniques used to stimulate demand, encourage purchase or sales of a product or services, reward royal customers and attract switchers from competitors,. Advertising provides information on a product or promote a brand. Sale promotion offers reasons to buy now. Here are a few examples of sales promotions: Coupons delivered in the newspaper offering discount on your favourite coffee. An e-mail from Amazon.ca offers free shippi ng on your next purchase over $35. Sales promotion uses different mix of promotional tools designed to stimulate customers to buy a product. There are two categories of sales promotion tools: The consumer promotions tools – aimed at consumers directly such as; price discount or same price for the twice the amount of the product, discount coupons, cash refund from the manufacturer, patronage rewards such as doubling the amount of air miles, sweepstakes such as possible chance to win a trip to Disneyland and free gift, getting something from the purchase.

Effects of Globalization on Loogistics Essay Example | Topics and Well Written Essays - 1500 words

Effects of Globalization on Loogistics - Essay Example The main setting of this paper is to highlight the impact of globalization on the current economic environment, with specific focus on the logistics and transport sectors. Nonetheless, the paper bases its argument on the fact that the process of globalization is undoubtedly transforming the logistical strategies employed by service and products providers. Globalization combines various actions and trends, which makes the impact of this process not only complex but also revolutionary.
