THE BACCHAE Essay Example For Students

THE BACCHAE Essay A monologue from the play by Euripides NOTE: This monologue is reprinted from The Plays of Euripides in English, vol. ii. Trans. Shelley Dean Milman. London: J.M. Dent Sons, 1922. TIRESIAS: Tis easy to be eloquent, for himThats skilled in speech, and hath a stirring theme.Thou hast the flowing tongue as of a wise man,But theres no wisdom in thy fluent words;For the bold demagogue, powerful in speech,Is but a dangerous citizen lacking sense.This the new deity thou laughst to scorn,I may not say how mighty he will beThroughout all Hellas. Youth! there are two thingsMans primal need, Demeter, the boon Goddess(Or rather will ye call her Mother Earth?),With solid food maintains the race of man.He, on the other hand, the son of Semele,Found out the grapes rich juice, and taught us mortalsThat which beguiles the miserable of mankindOf sorrow, when they quaff the vines rich stream.Sleep too, and drowsy oblivion of careHe gives, all-healing medicine of our woes.He mong the gods is worshipped a great god,Author confessed to man of such rich blessingsHim dost thou love to scorn, as in Joves thighSewn up. This truth profound will I unfold:When Jove had snatched him from t he lightning fire,He to Olympus bore the new-born babe.Stern Here strove to thrust him out of heaven,But Jove encountered her with wiles divine:He clove off part of th earth-encircling air,There Dionysus placed the pleasing hostage,Aloof from jealous Here. So men saidHereafter he was cradled in Joves thigh(From the assonance of words in our old tongueFor thigh and hostage the wild fable grew).A prophet is our god, for BacchanalismAnd madness are alike prophetical.And when the god comes down in all his power,He makes the mad to rave of things to come.Of Ares he hath attributes: he the hostIn all its firm array and serried arms,With panic fear scatters, ere lance cross lance:From Dionysus springs this frenzy too.And him shall we behold on Delphis cragsLeaping, with his pine torches lighting upThe rifts of the twin-headed rock; and shoutingAnd shaking all around his Bacchic wandGreat through all Hellas. Pentheus, be advised!Vaunt not thy power oer man, even if thou thinkestThat thou ar t wise (it is diseased, thy thought),Think it not! In the land receive the god.Pour wine, and join the dance, and crown thy brows.Dionysus does not force our modest matronsTo the soft Cyprian rites; the chaste by natureAre not so cheated of their chastity.Think well of this, for in the Bacchic choirThe holy woman will not be less holy.Thourt proud, when men to greet thee throng the gates,And the glad city welcomes Pentheus name;He too, I ween, delights in being honoured.I, therefore, and old Cadmus whom thou mockst,Will crown our heads with ivy, dance alongAn hoary pairfor dance perforce we must;I war not with the gods.

Policies in america essays

Policies in america essays One of the most important and interesting policies in America is the war on terrorism. The war on terrorism is interesting for many different reasons. The first reason why it is so interesting is because how close to home the terrorism struck. For many people when September 11th came it was just another ordinary day. Getting up out of bed, taking a shower, eating breakfast, going to work, or school, just doing there ordinary everyday routine. But when the time came when the world trade centers and the pentagon were terrorized everything changed. Now instead of doing your everyday routine, terrorism became a major part of your everyday life. Every time you picked up a news paper, turned on your favorite news program, or even listened to the radio all you herd about was the threat of terrorism. Maybe now since of terrorism getting to work is more difficult, and people have to worry about the treat of someone terrorizing there place of work with a bomb or many even anthrax. Secu rity now has to be tighter, especially in airports. Even the war in Iraq affects more and more people everyday. It might be a family member, or a friend but the everyday stress or worrying about that person can be overwhelming. Something has to be done with the threat of terrorism. Instead of us living our lives afraid of other peoples actions the United States people need to go back to the way things used to be. Not worrying what is going on in other countries every moment of the day. Not letting the terror meter tell us how we are going to live our lives. Not letting some other leader of a terrorist group deciding if we are going to go on vacation. Not letting them control our lives. ...

Talent Management In Abu Dhabi Aircraft Technologies Dissertation

Talent Management In Abu Dhabi Aircraft Technologies - Dissertation Example In the global business environment where competition is intense and a large number of multinational organizations compete with each other for the same markets, it is important that organizations value their competitive resources and make try to differentiate themselves from competition (Sandler, 2006). In most cases, the concept of competitive advantage means having a resource that is valuable and unique and which the other organization cannot easily emulate, thus having the benefit over our competition. This resource could be in the form of access to the scarce raw materials, innovative operational processes or having unique competencies in market distribution systems. However, more recently, human resources are too being recognized as a source of competitive advantage (Sullivan, 2004). Pre-established theories like organizational theory and agency theory help in reaching an understanding that human resources can provide a distinct and unique advantage to an organization, not only o n the basis of their skills and abilities, but also as a result of their commitment and engagement with their organizations (Romans, 2005). Worldwide surveys i.e. annual national surveys conducted by U.S. office of personnel management and other global organization like deloitte and CIPD etc, have revealed that organizations that have satisfied and happy employees were able to be more effective and perform better on indices like sales, revenue generation, customer satisfaction and customer loyalty.

Select one or more events to research and compare coverage of the Essay

Select one or more events to research and compare coverage of the event in a US news outlet and that of at least one other country - Essay Example In such a scenario what the media feeds the people plays a crucial role in their thinking and opinion. CNN a famous American based media channel reported about the issue. There is a difference between how the issue is portrayed by the media in Iran and America. The choice of words by CNN reporters portrays Iran as a rigid nation and is not cooperative when it comes to honoring the deal. The article states that Iran will only sign the deal ‘if sanction against Iran is lifted. On the other hand, a Middle East media channel known as The Jerusalem Post choice of words and style portrays America as untrustworthy and a dangerous nation when it comes to honoring deals. The article uses words such as ‘Iran not trusted to honor the deal by most in the US which portrays Americans as selfish and does not trust other people especially the Arabs easily. In both cases, it is clear that public relation technique is being applied. The agenda-setting theory is used in a case where the media manipulates how information is passed to the people in order to achieve an intended response. It is a common phenomenon in the democratic world today. Powerful politicians are who can pay more are portrayed as the most efficient politicians in comparison to other politicians. It all goes down to resources and political strategies applied (Carroll

The Criminal Justice System Research Paper Example | Topics and Well Written Essays - 2500 words

The Criminal Justice System - Research Paper Example An in-depth analysis of the criminal cases reported in Britain in the past elaborates that black males have been, more of than not, involved in a vast majority of the offenses committed by the black community. Representation of black women in the crime is far less than that of black men. In addition to that, male juvenile crimes make a large portion of the total crimes committed by the black community in Britain. Particularly, black males aged 13 to 19 are fundamentally responsible for the number of crimes committed by the British black community. In a recent survey conducted by (HCHAC, 2007), the percentage of boys from all ethnic origins who confessed having indulged in crime was 13% against a mere 7% of the girls that made the confession of the crime and this fact is also evident from the fact that male prisoners were found to be 70986 more in number than the female prisoners till February of 2007. This proves that black girls are definitely quite less in number than black boys wh o are suspected of the crime yet their representation in the British criminal justice system is far more than that of non-black girls. Although there is a lot of controversy about the black male teenagers’ involvement in crime in general, yet there is no denying the fact that they do make a considerable portion of the criminals in Britain. â€Å"At the peak teenage, 19, blacks suffer firearms murder rates 17 to 20 times higher than do whites.† (Males, 2008). In order to minimize the widespread susceptibility of black male teenagers towards crime, and minimize the number of real young black male teenagers remaining within the existing form of British criminal justice system, it is imperative that the factors that increase their susceptibility towards crime are identified and evaluated against other ethnicities. The chief causes that defame black male teenagers as a non-considerate and socially irresponsible community include, but are not limited to social exclusion, poverty, and low social status, lack of discipline, lack of sufficient education, social disaffection.

Airbus A380 And Boeing 747

Airbus A380 And Boeing 747 Airbus A380 and Boeing 747 are the new generation of aircraft for long haul and bulk passenger flights. The Airbus A380 holds 525 passengers whereas the Boeing 747 holds up to 452 passengers The feat of flying is a giant leap forward as well as flying with a huge passenger load. The project is to produce a conceptual design of a large civil aircraft using advanced computerised aircraft methods. The mission profile defined for this aircraft is long haul, matching the Airbus A380s range of 15km [6]. Also, the aircraft to be designed is to carry 550 passengers, even more passengers than the Airbus A380. This can only be made possible by a number of criteria but the biggest problem comes from keeping the aircraft airborne under an increased passenger and structural load. The required lift for an increased load of this magnitude mainly comes from the combination of the lifting surfaces and lifting control surfaces of the wing. Wings (SA) Aircraft wing designers have drawn their inspiration from birds. Even in this day and age, engineers are still finding ways to improve design based on examples found in the ornithological (branch of zoology that deals with the study of birds) world [14]. Wings are airfoils that are attached to each side of the fuselage of an airplane and are the main lifting surfaces that support the airplane in flight [13]. Wings can be of different designs, sizes, and shapes. Different types of wings are used by manufacturers depending on the mission of the aircraft. A variety of wing shapes are shown in Fig.1. Each fulfils a certain need with respect to the expected performance for the particular airplane. Wings may be attached at the top, middle, or lower portion of the fuselage. Passenger airplanes usually have low wings. The number of wings on an aircraft can vary, for example airplanes with a single set of wings are called monoplanes and those with two sets are known as biplanes.[13] Fig.1: Examples of wing planform [12] Planform styles Wings have evolved over the years from simpler designs as well as the Canard configuration (a configuration in which the span of the forward wing is substantially less than that of the main wing) and straight wings to futuristic designs such as oblique and morphed wings. The Canard configuration was founded by the Wrights brothers where the tailplane is in front of the straight wing. Many years of research have been carried out to improve the aerodynamic efficiency and performance of wings in aircraft and evidence of this can be found in the more futuristic designs for aircraft. For example, the oblique wing is a wing of large span fitted about a pivot that rests on the top side of the fuselage and the wing can rotate about this pivot giving one side of the aircraft a forward swept wing and the other, an aft swept wing and vice versa. The varying sweep angle and configuration was the pinnacle point of research and development for this aircraft and was created to give the pilot more f reedom into how the aircraft can be flown at different speeds. [8] Variable sweep wings allow the aircraft to take advantage of the greater lift and handling qualities that come with straight wings during low speed phases such as takeoff and landing and can also benefit from the reduced drag and improved aerodynamic efficiency that comes with swept wings during high speed phases such as the cruise phase. However, this wing configuration is more likely to be found on high performance aircraft like military aircraft rather than transport maybe due to the unpleasant flying characteristics that come with the extreme wing sweep angles which could have discouraged transport aircraft designers from adopting this configuration in their designs. [8] Evolution of aircraft wings (SA) There were few large aircraft in the 1950s. In those days, some aircrafts wings were built by using wood instead of metal. One reason wings were built using wood is because there were a shortage of metal at that time [17]. This is due to various reasons. One factor in favour of the wood wing was the quality of the ride in turbulence. The ride of a wood wing was better than a metal one. The quality of the ride in a metal wing was harsher and stiffer than the wood wing [17]. Also, the stall characteristics of the wood wing were much better than the metal ones. A disadvantage of wood wing was that it would have to be replaced early due to rot. In1961, wings were no longer made of wood [11]. Instead metal wing was introduced. The reasons for this were for marketing aspects, that is, metal wing last longer than a wood one. People think of rot when they think of wood. When they think of Aluminium, they think it will last forever. Morphed wing (SAJ and SA) The morphed wing started as a conceptual design when then a prototype was eventually built to test the proposed idea. It works by using in-built shape memory alloy actuators which deforms into a different pre-proposed shape when heated. This new shape gives the wings a new set of aerodynamic characteristics adapting to different flight conditions or for a change in mission. [9] Airbus is trying to use similar principles to morph aircraft wings to make them highly adaptable. A bird glides for maximum lift and folds its wings for reduced drag and this is the principle that is adopted from birds which made Airbus focus on wing planform. Professor Meguid of University of Toronto believes the technology behind the UAV morphed wing design could eventually be applied to civil aircraft. Meguid also states that some big airplane manufacturers are already interested in this technology and current research is being done to implement morphed wings [14]. On the other hand, Airbus senior manager of flight physics research, David Hills, disagrees with the idea of using morphed wing in commercial aircraft. He points out that unlike military aircraft, commercial airliners do not need to drop like a stone, therefore do not need morphed wings. [14] Morphing aircraft are multi-role aircraft that change their external shape significantly to adapt to a changing mission environment during flight. This in turn creates superior system capabilities which are not possible without the shape changes of the wing. The objective of morphing activities is to develop high performance aircraft with wings designed to change shape and performance substantially during flight to create multiple-regime, aerodynamically-efficient and shape-changing aircraft. Different Wing configurations (SAJ) Braced wing They are normally used in transonic aircraft designs just like the aircraft the group is designing. This truss braced wing configuration proved better than the normal cantilever because of its reduced fuel consumption and improved aerodynamic performance. The configuration can be altered to maximise different performance criteria for example if minimum fuel emission is desired then the wings have a lower thickness-to-chord ratio (are a lot thinner) and if the maximisation of the lift to drag ratio is desired then the wings are in contrast a lot thicker. The main desirable outcome from the use of having supporting truss wing configuration is the result of lower span wise bending moments for given loading. However, having this means a lighter wing structure, which results in needing an increased span (therefore greater lift to drag ratio), thinner wing and a reduced chord. The outcome is a more thin and slender looking wings that would therefore hold less fuel. If the wing could then in turn be designed with a high aspect ratio, it could minimise induced drag and as the wing is thinner, it will minimise the production of wave/form drag. [1] However, this configuration is not desired because of its high wing. Biplane Configuration (SAJ) Having two wings on each side aligned vertically from each other, all wave drag that is caused by the thickness of airfoil is eliminated. However, at small angles of attack, the flow is similar to flat plate except for a small wave drag penalty. When the flow becomes choked, a lot of wave drag can be produced and this is controlled from the use of hinge slats. However, this is not an ideal configuration for the transport aircraft to be designed as this configuration is mainly used in supersonic aircrafts, not transonic. [5] Joint wing configuration (SAJ) Joint wing configuration is when the tail is attached to the wing on both sides. The advantage of this configuration is greater control when pitching the aircraft and that the tail provides adequate structural support of the wings. It also produces less drag and has an overall reduced structural weight compared to structural aircrafts of same span. Reduced structural weight is due to the tail acting like a truss in support of the wing and relieving bending moment. Disadvantages of this configuration are that it needs a far greater wing span for it to cope with the take-off field length and constraints. [2] Also, with a greater wing span, there is greater drag and weight compared to conventional configurations as shown in Fig.10. Therefore a conventional low wing cantilever design is preferred for the design of this aircraft. Winglets (SAJ) Winglets are the small vertical structures at the end of the wings to reduce the effects of leakage of flow from the under surface of the wing. The effect of different taper ratios (SAJ) Small taper ratios ensure that the wing is strong enough so that all vortex shedding ceases. However, increasing the taper ratio will result in less induced drag so therefore, the aircraft can take advantage of a greater flight range from less drag, larger taper ratio. Lower taper ratio wings are lower in weight but can hold an increased fuel volume. So the preferred design of the wing will be to have a small taper ratio to keep the weight of the wing low without causing excessive variation in CL and stalling characteristics of the wing. [3] Dihedral / Anhedral Angles (SA) The dihedral angle, that is, the wing tip chord raised above the wing root chord, assists roll stability. Dihedral angle is normally between 2 and 3 degrees and rarely exceeds 5 degrees. The figure below shows the dihedral angle of a low-wing configuration. An advantage of a low-wing is it permits more ground clearance for the wing tip. The opposite of a dihedral angle is an anhedral angle. Anhedral angle lowers the wing tip with respect to the wing root and is typically associated with high-wing aircraft. (Aircraft Design, A. Kandu) (a) Dihedral (midwing low tail) (b) Anhedral (high-wing T-tail) Effects of dihedral angle (SA) The dihedral angle affects the lateral stability of the aircraft. The greater the dihedral angle, the more stable it is during roll. However, having a small dihedral angle can mean that it is less stable, but it can increase the manoeuvrability. When an aircraft is disturbed from upright position, that is, rolling, the aircraft sideslips towards the downgoing wing; the dihedral angle increases the angle of attack to lateral flow producing additional lift to restore straight and level flight. [4] Leading edge strakes (SAJ) Leading edge strakes is a component just in front of the wing and provides usable airflow over the wing at high angles of attack, delaying stall and consequently loss of lift. LEXES, another abbreviation for the stakes are very highly swept lifting surfaces that generate high speed vortexes at high angles of attack and attaches itself to the top of the wing. This is not really needed on a transport aircraft and is more apt for military aircraft which flies at high angles of attack at times and therefore not required. [4] Wing size/ wing loading (SA) Wing size or wing loading affects the following characteristics of an aircraft: Take off / landing field length Cruise performance (L/D) Ride through turbulence Weight of aircraft Take off / landing field length (SA) To achieve short field length, large wings (low wing loading) are better than small wings (high wing loading). The wing can be kept small by using flaps. Flaps provide the possibility to obtain high values of CLmax. Pilot uses flaps or slats to modify the shape and surface area of the wing to change its operating characteristics in flight. (Roskam, 1985) Cruise performance (L/D) (SA) To achieve cruise flight close to (L/D)max a high wing loading is needed so that the cruise lift coefficient can be close to that at (L/D)max. Weight (SA) The larger the wing area, the greater the weight of the wing and therefore the weight of the airplane. High, Middle or Low wing (SA) The choice of high, mid or low wing configuration depends on the mission of the airplane (passenger, cargo). Hence the type of airplane that is considered plays a vital role in deciding the vertical location of the wing. Low wing (SA) Low wing aircraft, as shown in Fig.14 are planes with the wing mounted below the main fuselage of the aircraft. Aerodynamically, there is not much difference between the two wing locations. [16] Advantages (SA) A Low wing aircraft provides superior visibility above and to the sides of the aircraft. The visibility advantage shows in turns when the pilot can see where the turn will go, even in a steep bank. On the other hand, a high wing aircraft will block the view in the direction of a turn. [16] Low wing aircraft are thought to be easier to land in a crosswind. The reason for this is more to do where the landing gear is placed rather than its aerodynamics. On a low wing airplane, the gear is fixed and can be spaced wider apart than on a high wing airplane where the landing gear must be attached to the fuselage. Also, the landing gear of a low wing plane can be mounted straight up and down, which allows a more effective shock absorption system. [16] Most planes carry fuel in the wings. The fuel ports of a low wing aircraft is easy to reach compare to a high wing aircraft. High wing airplanes require climbing up on the plane to re-fuel it. Low wing aircraft uses (SA) A low wing allows commercial jets to have the wing spar go through the fuselage below the passenger cabin. This leaves a lot of room in the passenger cabin with full headroom from front to back. Low wing commercial jets have their engines mounted quite close to the ground. These planes need to fly and taxi on airports where the pavement is kept clean of any debris that could be sucked up by those big jet turbines. This is one reason why military cargo planes use a high wing design, to mount the engines higher off the ground. [16] High wing (SA) A high wing aircraft is when the wing is mounted above the fuselage. High wing is where the wing crosses the fuselage at the top. Advantages (SA) A high wing aircraft provides the best visibility below the aircraft. High wing airplane is also safer in a descent because it avoids the possibility of coming down on another aircraft, especially on approach to the airfield or in the traffic pattern. Planform Tailoring (SA) Many airplanes end up with significant planform irregularities. This is where the use of planform tailoring comes into play. Some reasons for using planform tailoring are: stall behaviour, pitching moment behaviour at high mach, aileron buzz and aerolastic behaviour. [Roskam, 1985] To improve stall behaviour of wing, that is, delay stall to higher angle of attack, leading edge extensions and/or droop may be used. Aileron buzz can occur if the wing sections at the aileron stations develop shocks close to the aileron hingeline. If the aileron is cable controlled then the aileron can develop a severe vibration which is known as aileron buzz. Such problems can be relieved by leading edge extensions. References Gur, O. (2010).

Using the Roskam volumes, the aspect ratio of the Boeing 747 is 7.0 (Roskam, page 374) and 7.53 for the Airbus A380-100 (1). The wing span of the Boeing 747-400 is 229ft and the airbus A380 has a wing span of 261ft 9in (1). The reference wing area of the Boeing 747-400 is 6824 square feet and the reference wing area of the Airbus A380 is 9095 square feet (ft2)(1). The takeoff weight for our proposed aircraft is around about 1300000lbs (1221267.35lbs or 553957.5516901kg). The wings of the aircraft generates most of the total lift of the aircraft so in order for the aircraft to take flight, the lift would at least have to equal the weight of the aircraft. The lift equation is as follows: The velocity can be calculated through the equation where a= the square root of the product of Gamma (1.4), R (287) and the Temperature. The cruise Mach number specified for this aircraft (A380) is 0.89. The temperature at 35000ft, which is the cruising altitude proposed for this aircraft, is -54.23 Celsius which is 218.93 Kelvin. Hence, a = à ¢Ã‹â€ Ã… ¡1.4 ÃÆ'- 287 ÃÆ'- 218.93 = 296.59 Therefore the V = 0.89 ÃÆ'- 296.59 = 263.97 The coefficient of lift for takeoff is 1.6 -2.2, for cruise it is 1.2-1.8 and for landing it is 1.8-2.8, so take the coefficient of lift to be 1.8. The stall speed of an airbus A380 is 121kt (224 km/h) = 60.5 m/s and the 747X Stretch is 128kt (237 km/h) (1) So, say the stall speed of the proposed aircraft should be 128kt, or 65.792m/s Knot (kt) m/s 1 0.51 ft2 m2 1 0.0929 Rearrange, the lift equation to make the wing area the subject: = The density of air is taken at sea level to be 1.225 kg/m3 50 kt = 25 m/s Therefore, wing area = 553957.5516901/ 0.5 x 1.225 x 252 x 1.8 = 803.929 m2 Since the proposed aircraft is to be designed to carry more passengers than the airbus A380 and the Boeing 747-400, a larger wing span is proposed to create more lift, so b = 265ft. The aspect ratio can be calculated by: Aspect ratio= b2/S where S = Reference Wing Area and b = Wing Span A (Aspect ratio) of A380 = 7.53 (550 passengers) New A = 8 (an assumption based on having more passengers, 600) Aspect ratio= b2/S= 280^2/6824=10.29 Sweep Angle The sweep angle of the Boeing 747 is 37.5 degrees, the taper ratio is 0.25 and the dihedral angle is 7 degrees (Chapter 6, part II, page 146, Table 6.7, ROSKAM). In terms of the mission profile, size and configuration this aircraft is comparable to the A380. The sweep angle of the A380 is 33.5 degrees and taper ratio is approximately 0.3. (http://www.dept.aoe.vt.edu/~mason/Mason_f/A380Hosder.pdf). For the proposed aircraft, the sweep angle should be 30 degrees. Thickness Ratio the thickness ratio of the airbus a380 is 6%.

The Greatest Tunnel Ever! Essay -- Personal Narrative, essay about mys

The day had that perfect quality you always associate with childhood memories. I was eight, maybe nine, at the time of this particular memory, a small, ponytailed, freckled child with dirty legs and dirtier arms and face, full of energy and hope all children possess when looking forward to playing with other children. The sun shone through marshmallow-like clouds, and although it was only early afternoon, the tar road had started to bubble under my feet. The ponies tethered at the side of the road nickered at me in hope of an apple, but I was in too much of a hurry to oblige. Johnny, my equally dirty playmate, met me at the end of their driveway, his grin gaping where his big brother, Eddie, had accidentally knocked out his front teeth with a nine iron. "Let's check out those tunnels Eddie built last night," he demanded. The thought held no appeal for me whatsoever, but rather than show my reluctance and chance losing my only playmate, I pasted on a big grin of my own and followed him. We climbed the sloping lawn to the barn's entrance, where the doors, which were a color somewhere between grey and brown, stretched, from my viewpoint, to heaven. Johnny pulled on one door with all the strength in his puny body, but it refused to budge until I added my strength to his. Slowly, ever so slowly, it groaned a horrid sounding groan while begrudgingly swinging enough for us to squeeze through, scratching both stomachs and backsides in the process. The smell of the barn struck us a terrible blow after the air of the summer outside.

Johnny cried. I was amazed to see his flushed face devoid of any sign of illness or relief, but full of some fanatical form of worship for the maze which had nearly killed us. "Let's go through again before supper," he demanded. "I can't," I replied, pulling stray wisps of straw from my hair. "I have to be home early today." "Well, okay, I guess," he sulked, "but tomorrow for sure. Come on, I'll race you down!" And he was off in a flash toward the ladder. I let him win, just for good measure. The sun was overly bright to my contracted pupils, but I didn't notice. I was trying to think of a reason not to go through that particular version of hell again, but a reason wouldn't come, and I knew that when tomorrow got here, that's exactly where I'd be. Maybe Johnny would even let me go first. The Greatest Tunnel Ever! Essay -- Personal Narrative, essay about mys The day had that perfect quality you always associate with childhood memories. I was eight, maybe nine, at the time of this particular memory, a small, ponytailed, freckled child with dirty legs and dirtier arms and face, full of energy and hope all children possess when looking forward to playing with other children. The sun shone through marshmallow-like clouds, and although it was only early afternoon, the tar road had started to bubble under my feet. The ponies tethered at the side of the road nickered at me in hope of an apple, but I was in too much of a hurry to oblige. Johnny, my equally dirty playmate, met me at the end of their driveway, his grin gaping where his big brother, Eddie, had accidentally knocked out his front teeth with a nine iron. "Let's check out those tunnels Eddie built last night," he demanded. The thought held no appeal for me whatsoever, but rather than show my reluctance and chance losing my only playmate, I pasted on a big grin of my own and followed him. We climbed the sloping lawn to the barn's entrance, where the doors, which were a color somewhere between grey and brown, stretched, from my viewpoint, to heaven. Johnny pulled on one door with all the strength in his puny body, but it refused to budge until I added my strength to his. Slowly, ever so slowly, it groaned a horrid sounding groan while begrudgingly swinging enough for us to squeeze through, scratching both stomachs and backsides in the process. The smell of the barn struck us a terrible blow after the air of the summer outside. The stench of horse-flesh and manure filled the air, accompanied by the smells of overly-sweet straw and pungent leather harnesses. The stenches filled our noses and pe... ...ever built!"

Personal and professional development Essay

In essence, a team may be defined as two or more people who co-operate together with a common aim. A Team focuses towards common goals and clear purpose (park, 1990). The purpose of this report is to reflect on my experience on working in groups, effectiveness of group work, presentation skills, and reflect on the presentation skills. Effectiveness of the group work: The most popular and common model which explains the effectiveness of the team work is Tuckman (1965) the five stages group development model. According to Tuckman (1965) there are five stages of group development and these stages include: forming, storming, norming, preforming, and adjourning. The first stage of group development is forming stage, under this stage the team members are selected, and get to know each other, objectives are well defined, and tasks are identified. Group members try to identify a group leader and the other roles, and they try to find out what behaviors are acceptable to work in group. The second stage of group development is storming, this stage often characterized as conflict stage, where member tends to disagree on leadership, objectives and the rules. In addition, some members may feel dissatisfied with his or her group. The third stage of group development is norming, at this stage the group manages to have one objective goal and come to a common plan for the team. Some may have to give up their own ideas and agree with others to make the team function. In this stage, all team members take the responsibility and have the ambition to work for the success of the team’s objective goals. The fourth stage of group development is preforming, at this stage team members performed at the best of their abilities, and the project will be completed effectively and all the problems will be resolved at this stage. The last stage of group development is adjourning, at this stage the members will be happy due to team achievements of their group at the same time they might feel sad because they will be losing close friends when the project comes to the end. Belbin (1981) has researched and analysed effective group performance and recommends a new team model of nine different roles. These roles include: the coordinator, the shaper, the implementor, the monitor evaluator, the plant, the resource investigator, the team worker, the completer and the specialist. The coordinator is a person who has skills to organize, harmonize and control the team very well. The shaper is a person who makes things happens and encourages the team to action. The implemantor is the person who is hard working who like clear objectives and directions. The monitor evaluator is a person who solves the problems and evaluates the suggestions and the ideas. The planet is innovator, creator and inventor. The resource investigators are likeable, enthusiastic, creative and innovative, excelling under pressure through the improvisation. The team workers are the ones who improve the communications between the team members and foster team spirit. The completer is the person who Have all the necessary or appropriate parts and ensures about the targets and deadlines. The specialist contributes technical skills and he is self-motivated, committed and professional in his tasks. Belbin (1981) claims that if the team is incomplete in a team role, or has too many of the same types of role, it would be less effective team. Reflection on Group Work: To some extent our team follows Tuckman (1965) five stage of development but we removed the second stage which is storming. The team consists of four people and we are all friends we know each other’s from the beginning of the semester. . The purpose of the team is to write a report on Melaka trip. We divided the task each member is given a particular task and team leader assume the overall supervision role. These tasks include conducting interview, taking picture, and managing. Each member adopts different team roles based on our skills so as to ensure effectiveness of our team work. For instance, I assume the role of the monitor evaluator and specialist. I have technical skills of taking picture and also am good in analyzing problems and providing good suggestions. Indeed, our team managed to succeed because of our strong relationship, Since member are familiar to each other, the atmosphere was joyful, we were very happy to work together as team, we trust each other and we had achieved an excellent work together. Presentation Skills: According to Carlile and Hensley ( 2005) effective presentation includes planning and writing the presentation, effective use of visual benefits, overcoming nervousness, confidence in delivering and competent answering questions. For instance, presenter needs to understand the aim and purpose of the presentation that he or she will present, prepare well in advance, master the content and research on the audience in order to tailor the content to meet the expectation and understanding of the listeners. Moreover, Students who have a good foundation in literacy skills, with reading, writing and oral communication skills have bigger opportunities to experience the success as active fellow of society. Equally students, who have limited literacy skills, will find it difficult to make successful move from high school, to university. In addition, the success of leadership, teamwork and work place depends on communication skills (New London Group, 1996). Reflection on presentation skills: Before the presentation I was worried about what I well do and how I will speak but after I done my presentation I relaxed because I did a great job the tutor comments was good. Therefore, I have learnt many lessons from individual and group presentations and the tutor feedback that i will try to follow in my next presentations. Now am aware that oral communications skill is a way for successful life after university. I have weakness regarding to my presentation skills, and my weaknesses are: nervousness and weak preparation. Therefore, in order to succeed in presentations I will work harder in my future presentations and try to master the presentations skills. Conclusion: To sum up, I have learned many lessons during this semester and, this group and individual work that I have done so far. I have also learnt many skills and these include social skills, presentation skills, interpersonal skills and spirit of working together as team for mutual goals. Moreover, I have learnt how to communicate and work effectively with people even if I disagree with their ideas.

Reinsurance Group of America and Fonterra

Reinsurance Group of America and Fonterra: Going for Unified Global Operations CASE STUDY QUESTIONS: The business value of these global system developments for the companies mentioned in the case is very high. In case of RGA, the employees can analyze data by client, contract, and product and can find client errors very easily. This has been made possible because data is not stored at one place. This is very important for supporting the reinsurance business. It has made it easy to manage the reinsurance business.The global system developments help RGA data validation and data quality. This enables better risk analysis, and retention analysis leading to greater profits. Similarly in case of Fonterra the upgrading of the Fonterra business so that that the silos at the diary group are of large stainless steel variety. The global systems program aimed at improving the supply chain of a diary giant from cow to manufacturing to storage to customers. RGA achieved these benefits because it w as relieved of the problem of worrying about how the business should be managed.In addition, the system helps strengthen data validation and data quality. These useful benefits were achieved by engaging the business and adapting its own practices to the demand of the situation. The company has achieved the benefits by setting up an integrated, multicurrency, and Multilingualism. 2. Trying to implement a solution all at once is not feasible because many clients have essential operations that run during normal working hours and cannot afford the luxury of having their entire operation close down for a lengthy period in time.Often, clients have front office staff that attend to these operations (such as call centers, help desks, etc. ), and they work in 24-hour shifts. This is why many clients approve of a phased implementation approach, and the project team must ensure that the phased implementation is possible. This approach involves implementing the solution to a certain amount of u sers and then rolling them onto the new solution, while the rest of the users are olled out in a similar fashion, until the entire solution is rolled out within the client environment. The phase approach works well because (1) there is minimal disruption to the clients operation, and (2) problems are resolved quicker. The phased approach could also be used if there is more than one department. The project manager could decide that implementing the solution in one department at a time could be more reliable than trying to roll out all departments at the same time. 3.

Attack on Fort Sumter Began the Civil War in 1861

Attack on Fort Sumter Began the Civil War in 1861 The shelling of Fort Sumter on April 12, 1861 marked the beginning of the American Civil War. With the booming of cannons over the harbor in Charleston, South Carolina, the secession crisis gripping the country escalated into a shooting war. The attack on the fort was the culmination of a simmering conflict in which a small garrison of Union troops in South Carolina found themselves isolated when the state seceded from the Union. The action at Fort Sumter lasted less than two days and had no great tactical significance. And casualties were minor. But the symbolism was enormous on both sides. Once Fort Sumter was fired upon there was no turning back. The North and the South were at war. The Crisis Began With Lincolns Election in 1860 Following the election of Abraham Lincoln, the candidate of the anti-slavery Republican Party, in 1860, the state of South Carolina announced its intention to secede from the Union in December 1860. Declaring itself independent of the United States, the state government demanded that federal troops leave. Anticipating trouble, the administration of the outgoing president, James Buchanan, had ordered a reliable U.S. Army officer, Major Robert Anderson, to Charleston in late November 1860 to command the small outpost of federal troops guarding the harbor. Major Anderson realized that his small garrison at Fort Moultrie was in danger as it could easily be overrun by infantry. On the night of December 26, 1860, Anderson surprised even members of his own staff by ordering a move to a fort situated on an island in Charleston Harbor, Fort Sumter. Fort Sumter had been built after the War of 1812 to protect the city of Charleston from foreign invasion, and it was designed to repel a naval attack, not a bombardment from the city itself. But Major Anderson felt it was the safest place in which to place his command, which numbered less than 150 men. The secessionist government of South Carolina was outraged by Andersons move to Fort Sumter and demanded that he vacate the fort. Demands that all federal troops leave South Carolina intensified. It was obvious that Major Anderson and his men couldnt hold out for long at Fort Sumter, so the Buchanan administration sent a merchant ship to Charleston to bring provisions to the fort. The ship, Star of the West, was fired on by secessionist shore batteries on January 9, 1861, and was unable to reach the fort. The Crisis at Fort Sumter Intensified While Major Anderson and his men were isolated at Fort Sumter, often cut off from any communication with their own government in Washington, DC, events were escalating elsewhere. Abraham Lincoln traveled from Illinois to Washington for his inauguration. It is believed that a plot to assassinate him on the way was foiled. Lincoln was inaugurated on March 4, 1861, and was soon made aware of the seriousness of the crisis at Fort Sumter. Told that the fort would run out of provisions, Lincoln ordered ships of the U.S. Navy to sail to Charleston and supply the fort. The newly formed Confederate government kept up demands that Major Anderson surrender the fort and leave Charleston with his men. Anderson refused, and at 4:30 a.m. on April 12, 1861, Confederate cannon positioned at various points on the mainland began shelling Fort Sumter. The Battle of Fort Sumter The shelling by Confederates from several positions surrounding Fort Sumter went unanswered until after daylight, when Union gunners began returning fire. Both sides exchanged cannon fire throughout the day of April 12, 1861. By nightfall, the pace of the cannons had slowed, and a heavy rain pelted the harbor. When morning dawned clear the cannons roared again, and fires began to break out at Fort Sumter. With the fort in ruins, and with supplies running out, Major Anderson was forced to surrender. Under the surrender terms, the federal troops at Fort Sumter would essentially pack up and sail to a northern port. On the afternoon of April 13, Major Anderson ordered a white flag to be raised over Fort Sumter. The attack on Fort Sumter had produced no combat casualties, though two federal troops died during a freak accident at a ceremony after the surrender when a cannon misfired. The federal troops were able to board one of the U.S. Navy ships which had been sent to bring supplies to the fort, and they sailed to New York City. Upon arrival in New York, Major Anderson learned that he was considered a national hero for having defended the fort and the national flag at Fort Sumter. Impact of the Attack on Fort Sumter The citizens of the North were outraged by the attack on Fort Sumter. And Major Anderson, with the flag that had flown over the fort, appeared at a massive rally in New York Citys Union Square on April 20, 1861. The New York Times estimated the crowd at more than 100,000 people. Major Anderson also toured the northern states, recruiting troops. In the South, feelings also ran high. The men who fired the cannons at Fort Sumter were considered heroes, and the newly formed Confederate government was emboldened to form an army and plan for war. While the action at Fort Sumter had not amounted to much militarily, the symbolism of it was enormous, and intense feelings over what had happened propelled the nation into a conflict that would not end for four long and bloody years.

Relationships between Children and Parents. Write Me Sometimes and Essay

Relationships between Children and Parents. Write Me Sometimes and Hamlet - Essay Example They bond over a shared love of food and indulge themselves with all types of food when they meet up. They enjoy debating over restaurant choices and evaluating the food they eat, even when the protagonists’ sister begins to join them for their lunch dates, â€Å"The images I have in my head of these Saturdays are blurry, happy pictures† (Ng-Chan, Year). However, the relationship between father and daughter slowly changes for the worse as the daughter ages. Throughout her college life and subsequent years, she develops as her own individual identity and thus makes choices and forms opinions of her own which do not necessarily resonate with her father. Their weekly meetings almost stop completely, and when they do meet, it is evident that they have grown apart. What makes this even worse is a lack of effort on the part of the father. Though the protagonist writes regularly to her father in an aim to keep in touch and to keep him him informed of her life, the father merely rings very occasionally and never writes back, despite the fact that he promises to do so every time they speak. When they eventually arrange to meet in person again, the father is insistent that they meet for lunch, even though the daughter has made it clear she would prefer something else. The fact that the daughter is now vegetarian and her eating habits have changed drastically seems an issue her father cannot adapt to. He constantly questions her eating habits, encourages her to eat more and insists on buying her groceries constantly despite her protests, and their conversation is stilted, â€Å"The rest of the lunch was spent in polite enquiry† (Ng-Chang, Year). The father appears to be attempting to revert back to their childhood relationship through food and refuses to acknowledge that his daughter has changed. Paragraph 2 (Hamlet) In the Shakespearean play â€Å"Hamlet†, the reader is witness to tragic story in which the protagonists parents and their actions and weaknesses, ultimately lead to his demise. To begin with, after his father King Hamlet dies, the character of the younger Hamlet is immediately disturbed by the actions of his mother. Not long after his father’s death, Queen Gertrude engages in a relationship with and marries Claud ius, Hamlets uncle. This causes Hamlet to be distrustful and avoidant of women, as he believes that his mothers disrespect toward his father’s death and overt sexuality is characteristic of all women. It is as a direct result of this that he does not declare his love for Ophelia until she dies, â€Å"By what it fed on / and yet, within a month / let me not think on’t / Frailty, thy name is woman! / A little month; or ere those shoes were old / with which she followed my poor father’s body...† (Shakespeare, trans. 1992, 1. 2. 145-148). At the beginning of the play, the ghost of Hamlets father visits him and demands that he avenge his death as he asserts that it was Claudius who killed him. This immediately puts a huge pressure and sense of foreboding on Hamlet as his father has made it Hamlets mission to murder his uncle. It is in this preoccupation with deciphering Claudius’s guilt in the death of his father, that ultimately leads to Hamlets demise . Were it not for this idea of attaining revenge, Hamlet would not have engaged in the activities which led to his death. As Hamlets stepfather, Claudius plays a very central role in the death of Hamlet. Suspicious and afraid for his life, he arranges Hamlets death, as he did Hamlets father, and it was these actions which eventually led to the death of almost all of the characters in the play. Were it not for t

Answers to Exam Questions - Essay Example First, the model is simple and easy to understand as well as to implement. It should be noted that the variables in the formula can be easily accessed from public sources except the beta-coefficient which is not usually available for small and non-publicly traded business organizations. Secondly, it can be seen that the CAPM does not rely on dividends or have any assumptions on the growth of dividend which makes it applicable to companies that do not pay dividend or are not expected to experience a constant growth rate for dividends (Keown , et al. 2004). However, the CAPM is also widely criticized because it does not adequately explain the variation in stock returns. Empirical studies including the work of Black, Jensen, and Scholes reveals that low beta stocks may offer higher returns than the model would predict. CAPM will not also work for individuals which are risk averse as it assumes that investors will generally favor a stock with higher returns even if holding it entails more risks. Also, it can be seen that CAPM doesn't take into account the associated transaction costs and taxes (Capital Asset Pricing Model 2006). It should be noted that in using CAPM, companies with different debt leverage will generate different cost of capital even if they belong to the same industry. Debt leverage is reflected in the CAPM formula as the company's beta coefficient. Accordingly, higher debt leverage will yield to a higher as debt is seen a riskier source of financing. References: Capital Asset Pricing Model 2006, Retrieved 14 October 2006, from http://en.wikipedia.org/wiki/Capital_asset_pricing_model Keown, A., Martin, J., Petty, W., & Scott, D. 2004, Foundations of Finance, Upper Saddle River, New Jersey McCracken, M. E. 2005, CAPM, Retrieved 14 October 2006, from http://teachmefinance.com/capm.html 2. Debt leverage is the amplification of the return earned on equity when an investment or firm is financed partially through borrowed money (Walker n.d.). In order to illustrate how debt leverage works, let's look at a company who wants to buy a building as an investment which costs $1,000,000. In turn, it wishes to find customers who would want to rent the spaces. It expects to generate $15,000 per month. If the company has enough cash, it can immediately buy the building find tenants and can sell it at $1,200,000 after one year. Thus, the company will have a total gain of $380,000 from the sum of the rents and appreciation in the building's market value. This represents a 38% return on investment. However, if the company has only paid $200,000 and opted to borrow the remaining $800,000 with a mortgage rate of 12%, then the company will be paying $8,000 per month. Since interest payments are tax deductible, the company's monthly rent income of $15,000 will be more than enough to co ver the expenses. Even taking only the $200,000 appreciation of the building, the company is already able to recoup 100% of its initial investment. In the illustration above, we can see that debt leverage helps the company to maximize the gains of its
