Tragic Heroes of Illiad Essay Example for Free

Tragic Heroes of Illiad Essay Although Achilles and Hector are both mighty warriors who share the same values, they have different backgrounds, personalities, and reasons for fighting. Homer presents Achilles, the son of Peleus, a mortal, and of Thetis, a sea nymph, as a hero with almost supernatural characteristics. Achilles statue is godlike, his strength is superior, and his powers with a spear unsurpassed. He wears immortal armor and has talking horses. While Achilles is superhuman, Hector is completely human surrounded by his wife and child. As the eldest son of Priam and Hekuba, king and queen of Troy, Hector is the commander of the Trojan army. Hector has strong feelings of responsibility for his community. Troy is a center of culture with elaborate palaces and surrounds Hector and his family with stability. Achilles is a young, complex warrior capable of great cruelty and kindness. Homer always portrays him in extreme passion. He comes to Troy, knowing he will die because he wants honor and glory. He chooses glory and an early death, rather than a long, inglorious life. When Achilles argues with Agamemnon, Achilles reaction is deadly anger (1.190). Although he wants to fight, his stubborn pride compels him to sulk. He rejects pleas to return to the battle. In order to please Patroklos, Achilles finally compromises and allows Patroklos to return to battle wearing Achilles armor. Achilles allows Patroklos to go to his death. Only after Patroklos death does Achilles see that his sitting by his ships is a useless weight on the good land (18.104) which sacrificed many of his mens lives. Achilles is angrier than ever. He tears at his hair with his hands, and defiles it (18.27). Achilles anger, grief, and sorrow is expressed in vengeance. He wants revenge for Patroklos death. Grief stricken and raged, Achilles pursued Hector around walls of Troy 3 times, killed him and tied his lifeless body to his chariot and dragged it (22.401). Hectors fear of death is overcome by his fear of disgrace (7.215-18). Hector is more cautious, practical, and virtuous. Iris tells him to marshal the troops, and he does so (2.802). When Paris proposes a duel, Hector and Odysseus make practical arrangements while Priam and Agamemnon exchange the oath (3.264-317). Hector always appears as a hero of responsibilities. Hectors virtues are the outcome of his responsiveness to society. He is aware that his own virtues are conditioned rather than natural or spontaneous. He has schooled himself to play the warriors role and to be good (6.441-46). He does not question the order of things or shirk his duties. Although they both want glory, Achilles and Hector fight for different reasons. Achilles is an absolute hero who acts only for himself and for the glory of himself. He is an independent warrior in the army of Troy. He can return home when he pleases. His refusal to fight is an indication that he retains his independence. Achilles has no personal grievance against Troy (8.154). Achilles asked Zeus to help his enemies, the Trojans, kill his friends because his personal honor weighs more with him than the lives of his friends. He came to Troy, knowing he would die. He came because he cared so much for glory. He chooses glory and an early death rather than the pleasure of a long inglorious life (18.98). Hectors nobility and sense of loyalty demand that he fight. He is a hero of responsibilities; he never questions his responsibility to Troy. Hector places his life at the service of others. He fights for family and city, but he also fights so that he will not lose the respect of others. Hector is a warrior not because he loves war, but because he is provoked by his perception of his place in the social structure of Troy and of his obligation to the people.

Isomerism in Molybdenum Carbonyl Phosphine Complexes

Isomerism in Molybdenum Carbonyl Phosphine Complexes Part A Preparation and Identification of the Isomers of [Mo(CO)4(PPh3)2] Introduction Molybdenum carbonyl phosphine complexes with the general formula, [Mo(CO)4L2] where (L=PR3; R=Me, Ph etc) have an octahedral geometry. This means the complexes are able to display either cis or trans stereochemistry. Interconversion between the two isomeric forms is enabled through thermal Mo-P bond cleavage. Only the thermodynamically stable isomer of [Mo(CO)4(PPh3)2] is formed by direct reaction of Mo(CO)6 and PPh3. So in order to isolate both isomeric forms of the complex, [Mo(CO)4(piperidine)2] is used as an intermediate. The aim of this experiment was: The preparation of [Mo(CO)4(piperidine)2] by reaction of Mo(CO)6 with piperidine dissolved in toluene The preparation of cis-[Mo(CO)4(PPh3)2] by substitution of piperidine with PPh3 The thermal isomerisation of [Mo(CO)4(PPh3)2] to produce the trans isomeric form Characterization of the products by IR spectroscopy allowed the isomeric forms of each of the complexes to be identified, and the most stable form of the product to be deduced. Reaction Scheme Method Preparation of [Mo(CO)4(piperidine)2] A summary of the preparative details for the formation of [Mo(CO)4(piperidine)2] is detailed in table 1.1 Volume Weight Molar Mass Molar Amount Equivalence Density cm-3 g g mol-1 mol g mL-1 Mo(CO)6 1.00 264.00 3.788E-03 1.00 Toluene 15.00 12.98 92.14 1.408E-01 37.18 0.865 Piperidine 10.00 8.62 85.15 1.012E-01 26.73 0.862 Table 1.1 The preparative details of [Mo(CO)4(piperidine)2] Mo(CO)6 (1.00 g, 3.79 mmol) was dissolved in a mixture of toluene (15 mL) and piperidine (10 mL, 9.62 g, 101.00 mmol), under an inert atmosphere with stirring at 110 à ¢Ã‚ Ã‚ °C for 2 hours under reflux. The resultant yellow mixture was filtered under vacuum for 15 minutes, washed with ice-cold 60/80 petroleum ether (210 mL), to yield a yellow crystalline solid of [Mo(CO)4(piperidine)2]. Yield (1.19 g, 83%); ÃŽ ½max/ cm-1 3250.88 (N-H), 2931.85, 2853.10 (C-H), 2011.73, 1877.24, 1756.58, 1706.11 (C=O), 1476.99, 1462.33 (C-C) In order to calculate the yield of [Mo(CO)4(piperidine)2] formed, the following method was employed, with details summarised in table 1.2. Mass Obtained Molar Mass Moles Theoretical Yield Percentage Yield g g mol-1 mol g [Mo(CO)4(piperidine)2] 1.19 378.30 3.146E-03 1.433 83.05 Table 1.2 The yields for the formation of [Mo(CO)4(piperidine)2] The theoretical mass of [Mo(CO)4(piperidine)2] was calculated from its molar mass and the number of moles of the limiting reagent, Mo(CO)6 , using the following equation eq.1.1 On formation of [Mo(CO)4(piperidine)2] the yield of the complex was actually obtained to be 1.19 g. So in order to work out the percentage yield of [Mo(CO)4(piperidine)2] formed, eq 1.2 was used Preparation of [Mo(CO)4(PPh3)2] (Isomer A) by Substitution of Piperidine with PPh3 A summary of the details of preparing [Mo(CO)4(PPh3)2] (isomer A) is given in table 1.3 Volume Weight Molar Mass Molar Amount Equivalence Density/ g mL-1 cm-3 g g mol-1 mol g mL-1 [Mo(CO)4(piperidine)2] 0.50 378.30 1.322E-03 1.00 PPh3 0.75 262.29 2.859E-03 2.16 CH2Cl2 10.00 13.25 84.93 1.560E-01 118.04 1.325 [Mo(CO)4(piperidine)2] (0.50 g, 1.32 mmol), triphenylphosphine (0.75 g, 2.86 mmol) and CH2Cl2 (10 mL) were refluxed at 40 à ¢Ã‚ Ã‚ °C, under an inert atmosphere for 15 minutes. The reaction mixture was allowed to cool to room temperature. Then methanol (15 mL) was added to the mixture and cooled in the freezer for 30 minutes. The precipitate was filtered under vacuum for 15 minutes which yielded a pale-yellow solid of [Mo(CO)4(PPh3)2](isomer A). Yield (0.43 g, 44%); ÃŽ ½max/ cm-1 2925.53 (C-H), 2011.26, 1876.74, 1756.04, 1706.81 (C=O), 1462.87 (C=C). The yields of the product, [Mo(CO)4(PPh3)2] (isomer A) are summarized in table 1.4.

However in this case the limiting reagent was found to be [Mo(CO)4(piperidine)2] Preparation of [Mo(CO)4(PPh3)2] (Isomer B) by Thermal Isomerisation of Isomer A Table 1.5 shows a summary of the preparative details of [Mo(CO)4(PPh3)2] (isomer B) Volume Weight Molar Mass Molar Amount Equivalence Density cm-3 g g mol-1 mol g mL-1 [Mo(CO)4(PPh3)2] (Isomer A) 0.40 732.58 5.460E-04 1.00 Toluene 4.00 3.46 92.14 3.755E-02 68.77 0.865 Since isomer A was produced in a relatively low yield, the thermal isomerisation reaction was scaled so that only 0.4 g of isomer A was used. [Mo(CO)4(PPh3)2] (isomer A) (0.40 g, 0.55 mmol) was added to toluene (4 mL) and stirred under reflux at 110 à ¢Ã‚ Ã‚ °C for 30 minutes under an inert atmosphere. The solution was cooled to room temperature and 60/80 petroleum ether (9 mL) was added to aid precipitation. The resultant mixure was filtered under vacuum for 15 minutes, rinsed with 60/80 petroleum ether (2 x 5 mL), which yielded a brown solid of [Mo(CO)4(PPh3)2] (isomer B). Yield (0.26 g, 65%); ÃŽ ½max/ cm-1 3056.60 (C-H), 1873.38 (C=O), 1476.92, 1431.71 (C=C). The yields of the product, [Mo(CO)4(PPh3)2] (isomer B) are summarized in table 1.6 Mass Obtained Molar Mass Moles Theoretical Yield Percentage Yield g g mol-1 mol g [Mo(CO)4(PPh3)2] (Isomer B) 0.26 732.58 3.549E-04 0.400 65.00 As before using eq.1.1 and eq.1.2 the percentage yield was calculated from the theoretical yield. Results and Discussion This experiment involved the isolation of the two geometrical isomers of [Mo(CO)4(PPh3)2]. Only one of these isomers can be isolated from the direct reaction of PPh3 with [Mo(CO)6]. This reaction requires a long reaction time and high temperatures but yields the more thermodynamically stable geometrical isomer. So in order to isolate the isomer B, an alternative synthetic route was employed. A precursor in the form of [Mo(CO)4(piperidine)2] was used to yield isomer B, since PPh3 is now able to readily substitute piperidine. This method relies on the nature of the ligands. Piperidine is a weak field ligand, and so forms a relatively weak dative bond with the molybdenum ion. However, PPh3 is a strong field ligand and so binds strongly with the central metal ion. This means PPh3 easily displaces the piperidine ligands to give rise to the isomer B form of the complex [Mo(CO)4(PPh3)2]. The first part of the reaction involved the preparation of the intermediate [Mo(CO)4(piperidine)2] which is a yellow solid which is in agreement with literature. The complex was formed in good yield at 83%. The infrared spectrum of [Mo(CO)4(piperidine)2] shows four peaks corresponding to C=O vibrations at 2011.73, 1877.24, 1756.58 and 1706.11 cm-1 (lit). This suggests the isomer of the complex formed is the cis geometrical isomer. This can be explained by employing a group theory technique, which uses an unshifted C=O bonds procedure, as illustrated in figure. E C2 ÏÆ'(xz) ÏÆ'(yz) à Ã¢â‚¬Å"CO 4 0 2 2 Cis-[Mo(CO)4(piperidine)2] has C2V symmetry and the irreducible representation of unshifted bonds is deduced to be 2A1 + B1 + B2. Since all of these operations are IR active, four peaks are expected in the carbonyl region of the spectrum. In the IR spectrum there is also a peak at 3250.88 which corresponds to an N-H bond. This is indicative of unreacted piperidine. The presence of residual piperidine did not negatively affect the experiment to any significant extent. The synthesis of [Mo(CO)4(PPh3)2] (isomer A) yielded a pale yellow solid as reported by. The complex produced a 44% yield which affected the proceedings of the reaction as enough product was not formed. This meant the subsequent reaction had to be scaled down. The IR spectrum of [Mo(CO)4(PPh3)2] (isomer A) displayed four peaks in the carbonyl region at 2011.26, 1876.74, 1756.04 and 1706.81 cm-1 which were similar to those reported in the literature. The compound was also determined to have C2V symmetry which would therefore be expected to give rise to 4 peaks in the spectrum. Therefore isomer A is cis-[Mo(CO)4(PPh3)2]. As a result, it can be deduced that isomer B of [Mo(CO)4(PPh3)2] is the trans geometrical isomer. The trans isomer has a D4h point group and so is expected to produce a single peak in the IR spectrum. As predicted, the spectrum of isomer B has a peak in the carbonyl region at only 1873.38 cm-1. The trans-[Mo(CO)4(PPh3)2] isomer was a brown solid and produced at a reasonable yield of 65%. The trans isomeric form of [Mo(CO)4(PPh3)2] is the thermodynamically more stable form of the two isomers. The trans isomer required more vigorous reaction condition such as the solvent heated to 110 à ¢Ã‚ Ã‚ °C and a longer reaction time as opposed to the milder conditions used for the formation of the cis isomer. The trans isomer places the two bulky PPh3 ligands as far as possible from one another, at 180 à ¢Ã‚ Ã‚ ° apart, which gives the complex the lowest possible energy. Cis-[Mo(CO)4(PPh3)2] is the kinetic product of the reaction since it forms at a faster rate. This is because the activation energy barrier is much smaller, as reflected by the mild conditions imposed (40 à ¢Ã‚ Ã‚ °C toluene, 15 minute reflux). Conclusion The synthesis of all three complexes was successful. A good yield was obtained for the formation of [Mo(CO)4(piperidine)2] at 83%. However, isomer A of [Mo(CO)4(PPh3)2] was produced at a relatively low yield of 44%, in comparison to 65% produced for isomer B. The low yield of isomer A affected the proceedings of the subsequent steps of the reaction, and so required a scaling down of reagents used from this point onwards. The infrared spectrum of [Mo(CO)4(piperidine)2] produced four C=O stretching bands at 2011.73, 1877.24, 1756.58 and 1706.11 cm-1; which matched those reported in literature. This suggested that the complex had a cis geometry and therefore the point group of the complex is C2V. For isomer A of [Mo(CO)4(PPh3)2], the point group was also inferred to be C2V. using the method of unshifted C=O bonds, it was determined that four peaks are expected in the spectrum corresponding to C=O vibrations. The infrared spectrum obtained did indeed have four bands at 2011.26, 1876.74, 1756.04 and 1706.81 cm-1. This shows good correlation with the predictions from group theory. For isomer B of [Mo(CO)4(PPh3)2], the spectrum displayed a single peak at 1873.38 cm-1 which corresponds to C=O. The geometry of the complex is therefore confirmed to be trans, and the point group deduced to be D4h for the complex. The colours of the complexes showed good agreement with that reported in literature. The intermediate complex [Mo(CO)4(piperidine)2] was yellow in colour. The cis isomer of [Mo(CO)4(PPh3)2] was pale yellow, whilst the trans isomer was brown. To summarize the products were produced in reasonable yield, and the IR spectra along with group theory allowed the distinction of the isomeric forms of the complexes. Questions A complex ion is formed when a d-block transition metal ion forms a coordinate bond by accepting a pair of electrons from a ligand. A ligand is an ion or molecule that surrounds the metal ion and is able to donate a pair of electrons to it. This means the ligand is a Lewis base, whilst the central metal ion functions as a Lewis acid. There are two types of bonding between a d-block transition metal and a ligand, namely ÏÆ'-bonding and Ï€-bonding. ÏÆ'-bonding is present in all interactions between a metal and ligand because the lone pair of the ligand lies on the internuclear axis. However, some ligands are able to participate in Ï€-bonding interactions. A ligand is said to be a Ï€-donor ligand if the interaction involves donation of electron density from a filled orbital towards an empty metal orbital. It is also possible for a ligand to be a Ï€-acceptor ligand. In this case, electron density is donated from a filled orbital on the metal to an empty orbital on the ligand. The bonding between a d-block transition metal and specific ligands is discussed below: C≠¡O Carbon monoxide is a strong field ligand with its position high in the spectrochemical series, which means that it gives rise to low spin complexes, due to the fact that it has a large value of Δoct. There are two components that describe the metal carbonyl bonding. ÏÆ'-bonding – when a lone pair of electrons from C≠¡O is donated to an empty d-orbital on the metal, this is known as ÏÆ'-bonding. Ï€-acceptor ligand – when electrons from the filled metal d-orbital are donated to an empty Ï€* acceptor orbital on CO, this is known as Ï€-back donation. CO is both a ÏÆ'-donor and Ï€-acceptor ligand. Since these components complement one another, this results in synergic bonding. In other words, the greater the ÏÆ'-donation the greater the Ï€-back donation. However the extent of backbonding does depend on the oxidation state of the metal and the electronic properties of the other ligands present. Structurally, as a result of synergic reinforcing components, the metal carbonyl bond strength is increased, but this means the C≠¡O is weakened, relative to free C≠¡O gas. This is due to an increase in the electron density of the antibonding Ï€* orbital. PPh3 Triphenylphosphine has a lone pair of electrons on P that it is able to donate to the transition metal centre, and so acts as a ÏÆ'-donor ligand as illustrated in figure†¦. The phosphine has a vacant orbital, so in theory it can also act as a Ï€-acceptor ligand. However, the 3d orbitals that are vacant on phosphorus may be of too high energy for Ï€-backdonation to occur. Instead the ÏÆ'* orbital contributes as the main acceptor component. The ability of a phosphine ligand to act as an acceptor is controlled by the identity of the R substituent. Since in PPh3, the substituent is phenyl which is not a very electron-withdrawing group, the Ï€ acceptor properties are weak. This is because the phenyl rings are not electron-withdrawing enough to lower the energy of the 3d orbitals on phosphorus. However, if the R substituent was replaced by an electron-withdrawing group, the Ï€ acceptor properties of the phosphine group would be greater. To summarise, PPh3 is a good donor but a poor acceptor. Piperidine The molecular formula of piperidine is C5H10NH and the structural formula is displayed in figure†¦. Piperidine can act as a ligand because the nitrogen atom has a lone pair of electrons. However unlike CO and PPh3 it is classed as an intermediate field ligand. Piperidine is able to donate its lone pair of electrons on nitrogen to the transition metal centre, and so is said to act as a ÏÆ'-donor. However since the nitrogen atom only has one lone pair of electrons, it is unable to participate in Ï€-backdonation. [Mo(CO)4L2] where L exists as piperidine or PPh3 may exist as two different geometrical isomers: cis or trans. By considering only the C≠¡O bond of the compound in the infrared spectrum and by exploitation of group theory, the molecular arrangement of the compounds prepared could be determined. Cis For cis-[Mo(CO)4L2] the point group was identified to be C2V (since it has a C2 axis, ÏÆ'(xz) and ÏÆ'(yz) components). In the case of cis-[Mo(CO)4L2] the character table for C2V is CHARACTER TABLE C2V here Since only the C≠¡O bonds are being considered, the reducible representation of the number of unshifted C≠¡O bonds under each operation of the point group is detailed in table†¦Ã¢â‚¬ ¦. E C2 ÏÆ'(xz) ÏÆ'(yz) à Ã¢â‚¬Å"CO 4 0 2 2 The reduction formula provides a means of converting a reducible representation into a sum of irreducible representations Where ai= number of times an IRREP contributes to the reducible representation; h= total number of symmetry operations, nR= number of operations in a class; χ(R) = character in reducible representation; χIR= character in IRREP Therefore when the formula is applied to each line of the character table we get: So overall à Ã¢â‚¬Å"CO = 2A1+B1+B2 The complex was then described in terms of vibrational modes, à Ã¢â‚¬Å"CO E C2 ÏÆ'(xz) ÏÆ'(yz) à Ã¢â‚¬Å"CO 2 0 1 1 Using table (C2v character table) it can be seen that A1, B1 and B2 are all infrared active. Therefore cis-[Mo(CO)4L2] would be expected to give rise to four peaks in the vibrational spectrum. The same process was carried out for the trans isomer in order to determine the number of IR active bands in the vibrational spectrum. Trans For trans-[Mo(CO)4L2] the point group was identified to be D4h In the case of trans-[Mo(CO)4L2] the character table for D4h is CHARACTER TABLE D4h here Since only the C≠¡O bonds are being considered, the reducible representation of the number of unshifted C≠¡O bonds under each operation of the point group is detailed in table†¦Ã¢â‚¬ ¦.

People say that the first step to success is finding out what you want and then giving yourself to it with all your heart. I have partly found myself by making one of the most important decisions of my life - choosing a profession, and now I study Management at YSU’s faculty of Economics. I have to admit that I haven't always been a student with top marks as I connected my goal of becoming a good specialist with an experience rather than a qualification. Now I realize that the harder I work at the university, the closer I get to my profession. However, like most of my fellow students, I dream of breaking out of my academic routine and getting skills that standard lectures will never provide. Through applying to this project I have made my decision on choosing an exchange country that fits me most, and I hope that I fit it either, with my statements that are introduced below. Several things interest me about the US as an exchange student, and I want to introduce them from practical, sociocultural and after all, a little bit â€Å"selfish† aspects. First, US Universities have much to offer me as a student by giving out an opportunity to study precisely what I’m interested in, in a more different way than I've been used to in my current university. In other words, American education methods meet students’ objectives and raise analytical thinkers with skills of a potential leader. That is part of what makes it such an interesting place to study. Besides, studying in a country with mixed culture which is also filled with international students has another advantage: that is becoming part of the Global youth and exploring my opportunities, obtaining self-confidence, as well as breaking some stereotypes through interactions and ... ...a western education they are motivated to make major contributions to the development of their countries with a clear aim of building a democratic society by sharing experience and knowledge with others. I have the qualities of struggling for the implementation of the goals that I have always wanted to achieve and even if they don’t work sometimes, at least I know that I dreamed out loud. So I would like to study in the USA by means of this program, because it teaches a lot in a short time and it’s a once-in-a-lifetime opportunity. Thus, I am ready to be an exchange student for my willingness to continue the endeavors of Global UGRAD alumni: i.e. I have to be a good ambassador of my country, enrich my knowledge reservoir and use it for the benefit of the public sector in my community. This is my full understanding of what is required from any exchange student.

The War On Drugs Essay -- Drugs, argumentative, persuasive

The â€Å"War on Drugs† is the name given to the battle of prohibition that the United States has been fighting for over forty years. And it has been America’s longest war. The â€Å"war† was officially declared by President Richard Nixon in the 1970’s due to the abuse of illegitimate drugs. Nixon claimed it as â€Å"public enemy number one† and enacted laws to fight the importation of narcotics. The United States’ War on Drugs began in response to cocaine trafficking in the late 1980’s. As the war continues to go on, winning it hardly seems feasible. As stated by NewsHour, the National Office of Drug Control Policy spends approximately nineteen billion dollars a year trying to stop the drug trade. The expenses shoot up, indirectly, through crime, hospital stays and such. However, people spend approximately three times as much money buying drugs as the government spends fighting against them. How can this war be won when the government has to spend so much money combating in opposition to it On top of the ridiculous cost of all the factors of the war, the availability of the illegal drugs comp...

Economic Impact Of The Development Of Airline Industry Essay

Hardly many inventions can manage to change the way people live and also how they experience the world like the way inventing airplane has done. The airline industry offer air transport for passengers. The airlines companies own the airplanes or may lease them. Airlines Company differs in terms of capacity, some are smaller with one or two airplanes to transport mail and cargo, while other are big multinational companies with hundreds of aircrafts. Majority of airlines are privately owned, though some are government owned. Today, the air travel has grown to an extent that no one can imagine life without it. Air travelling as greatly reduced travelling time and opened up links all over the world. Economic Impact of the development of airline The air airline industry has played a major role in world economic growth; it has improved the mobility and facilitated world supply lines all over the world. The aviation industry not only serves as an economic tool for nations and cities, but also servers as a vital network for transport within the world. The industry creates jobs by providing them directly and also by creating opportunities in the travel and hotel industry. Aviation industry has continued to be critical in the world economy, in terms of creating these job opportunities, and the industry has employed thousands of employees in the whole world. And has the industry continue to grow more jobs are created. This leads to economic growth. Transport plays a major role in making sure that goods reach their destinations. The World Bank estimates that the airline industry contributes to a total of 5% economic growth in the world. Competition Competition in the industry can be traced back when most governments deregulated the industry I order allow competition among the industry to regulate fares. For many years now this resulted in low fares as the airline industry responded to customers needs. Most of the reduced fare also comes from new players on the market, and also from the big airlines themselves. With the growth of economy in many countries, more travellers are using the air, this id due to the fact that the fares have also been reducing gradually. In a report carried out in America by the senate, it was found out that competition has resulted into low fares, and from 1990 the traffic has gone up by over 33%, it was found out that the number of flights had also gone up to over 20%. This of course has a positive impact on economic growth. Competition in the industry has also lead to mergers as small companies fail to compete. This has improved the industry service delivery. It is important to note better service delivery has economic advantage. With the economic development being witnessed in many countries, the amount of travelling has gone up. Many people are travelling to transact their business. The high demand of air passengers has caused resource constraints, on airports and also on airways, especially during the peak travelling periods. Business community usually travels at these times and normally makes last minute bookings. However, main airlines have planned their networks to be able to meet the high rate flight requirement by the business passengers, though; these fares are expensive as the airlines need to cover cost of servicing high number flight. Nevertheless, airline competition and the way they price their tickets causes concerned. It has been noted that, with the emerging of low fare trends that have been occurring since 1996, when smaller airlines enter into this market with low fares, the major airlines drastically reduce their prices. And also avail a high number of low fare seats. This behaviour seems to be ill intended because it aims at repressing competition from the smaller airlines. Increase in fuel prices Oil and fuel prices have continuously increased for the past 10 years, for example, in 2001 the price per barrel was $20, yet in 2006 it had reached $75. The increase in price can be attributed to various such as, high demand of oil, collapse of Yukos Oil Company in Russia and political instability in the Middle East. This high increase in oil prices has affected the aviation industry. The increase in fuel prices has lead to reduction in the global trade. It is estimated that about 40% of goods traded on the world market are transported by the air, and cargo traffic is used to reflect economic growth. Fuel account for 20-30% of the total cost of operation expenses of the airline industry. Due to this high cost in oil the economy has suffered negatively. The microeconomic effect for those countries which import oil will be harsh, in the industry high prices is a big problem; the companies are forced to increase consumers’ fares to upset the fuel price increase, for example if fuel price reached 100$ per barrel, then a gallon of jet fuel will be more than 3$. This will imply that a passenger will have to pay 50$ more to travel than previous. This will result in reduction of passengers and for the case of cargo transporters it may lead to high reduction in demand of their services, which may spell down for the airline companies. The indirect impact on the airline industry caused by high fuel prices in the increase in airline products prices. The overall impact is reduction in international trade. As pointed out by the world trade organisation , increase in oil prices leads to low economic growth as it was observed in 2005. Terrorist threat Since the September 11 terrorist attack, the airline industry suffered so much, the industry experience a reduced number of passengers as many opted to use alternative means. The economic impact on the global level was immerse, has many countries experienced low foreign exchange due reduced business especially in tourism industry. The terrorist attack had a big effect on the aviation industry, and also on the economy. In America alone, more than 2 million passengers travel on air daily. Airline industry and tourism alone account for mote than 8% the world GDP. With the imminent threat of terrorism, the industry has undertaken different security measures. For example in America, the industry has to use over 11$ billion in security improvements. This costs at the end of the day have to be met by the passengers, thus, the fare in the industry have steadily gone up. This has reduced the volume of goods and passengers using the industry and negatively affected the economy. Any small distractions in the industry send shock waves in many other industries. Currently, the industry has experienced a trend by which they are weak economy, insecurity fear and other issues. This has led to reduced number of passengers flying. Even those passengers who are flying they are paying less because most of them are taking economy seats. This trend has resulted in decline of the growth of the industry. In decline in the industry usually result in reduction of economy growth of the world economy. After the September 11 many airline companies grounded their business due to security concerns this was so pronounced in America. The impact of the attack reverberated all over the world. It was estimated that the attack caused a reduction of 1% world economic growth. In this area of global economy the aviation industry all over the world suffered. The industry saw an increase in costs of airline insurance, increased expenses on security, and customer fear to travel using the air due to insecurity. This led to massive losses for the industry in the whole world. This was the worst disaster the industry had suffered in the past 50 years. In whole world more than 400,000 jobs were lost. Decline in the air travel has a direct consequence on number of business which includes tourism, travel agencies and entertainment spots, this is felt global. It is important to note that, in the continuous threat of terrorist, the world economy has been affected badly. The industry had to go through lean times and some companies had to shut down. Conclusion The airline industry is very important in economic development, the airline employees a lot of people directly and indirectly. The industry has developed steadily over the last 50 years, and has continuous grown. Competition, fuel increase and terrorist attack pose a serious challenge to the industry and the industry should come up with ways to controlling these effects to maintain profitable. However, the airline industry will continue to grow though, it will be faced with more challenges.

Evaluating Advertising Campaign

Evaluating Advertising Campaigns It is through the process of review and evaluation that an organization has the opportunity to learn and develop. In turn, this enables management to refine its competitive position and to provide for higher levels of customer satisfaction. The use of marketing communications is a management activity, one that requires the use of rigorous research and testing procedures in addition to continual evaluation. This is necessary because planned communications involve a wide variety of stakeholders and have the potential to consume a vast amount of resources. The evaluation of planned marketing communications consists of two distinct elements: The first element is concerned with the way the ad communicates. Thus, it deals with the development and testing of individual messages. An advertising message has to achieve, among other things, a balance of emotion and information in order that the communication objectives and message strategy be achieved. To accomplish this, testing is required to ensure that the intended message is encoded correctly and is capable of being decoded accurately by the target audience. This testing could be pre or post testing. The second element concerns the overall impact and effect that a campaign has on sales once a communication plan has been released. This post-test factor is critical, as it will either confirm or reject management’s judgement about the viability of their communication strategy. THE ROLE OF EVALUATION IN PLANNED COMMUNICATIONS The evaluation process is a key part of marketing communications. The findings and results of the evaluation process feed back into the next campaign and provide indicators and benchmarks for further management decisions. The primary role of evaluating the performance of a communications is to see that the advertising objective has been met and that the strategy has been effective. The secondary role is to ensure that the strategy has been executed efficiently, that the full potential of the individual promotional tools has been extracted and that resources have been used economically. TOO MUCH OR TOO LITTLE? Companies are generally interested in finding whether they are overspending or underspending in advertising. One way to figure that out is to use the formula given below. Share of voice is the company’s share of advertising expenditure that earns a share of the consumer’s mind, and ultimately the market. Comparing that to market share provides an idea as to the feasibility of the company’s ad spend. An advertising effectiveness ratio of 1 means an effective level of ad expenditure, while a ratio less than 1 indicates a relatively ineffective advertising level. As can be seen from the above table, firm A spends Rs. 20 lakhs of the total industry expenditure of Rs. 35 lakhs. Thus, its share of voice is 57. 1%. However, its market share is only 40%. So we can say that firm A is either overspending or misspending. Firm B has a market share equal in proportion to its share of voice. It spends effectively on advertising, while firm C is super efficient, and could probably increase expenditures.
