Odysseus and Supernatural Beings

Odysseus and Supernatural Beings Throughout Homer's Odyssey, there are many supernatural beings that interact with Odysseus. These beings play an important role as either advisors, temptations or foes to Odysseus. Throughout his journey he is confronted with conflicts where he is either helped or hindered by these supernatural beings. Below are some examples of the beings that either helped or hindered Odysseus during his journey. The goddess Athena, goddess of wisdom and war, is the most powerful intelligent and influential woman in Odysseus’s life. She is always at his side. She speaks on behalf of Odysseus, telling Zeus, her father, that her heart breaks for forlorn Odysseus. Odysseus longs to see the curls of smoke rising from his home fires in Ithaca, she says, but Calypso will not loosen her hold on him. She reminds Zeus that Odysseus dedicated many burnt offerings to him at Troy. Swayed by her words, Zeus sends the messenger god, Hermes, to Calypso’s island with a command to release Odysseus. Athena aids Odysseus in many ways throughout his entire journey, like when she changes the course of events that take place when he first meets the princess Nausicaa of Phaeacia. Athena changes the course of the ball that the girls are throwing so that it falls on Odysseus and wakes him up, leading him to meet Nausicaa. Many times Athena convinces Zeus and the other Gods that Odysseus is worth saving. Perhaps the most formidable foe of Odysseus is the sea god Poseidon, who continually attempts to thwart the efforts of Odysseus to make a safe journey home. On one of Odysseus adventures he angers the great sea god, Poseidon, by blinding his son, Polyphemus, king of a race of one-eyed giants who inhabit the island of Sicily. In retaliation, Poseidon relentlessly torments Odysseus after he leaves Sicily, imperiling his voyage at every turn. He is aware that he cannot kill nor stop Odysseus but continues his efforts to make Odysseus journey throughout the story full of peril. An example of Poseidon’s wrath is seen as soon as he arrives back from Ethiopia and spots Odysseus making passage towards Phaeacia, he says, â€Å"Just look at him there, nearing Phaeacia’s shores where he’s fated to escape his noose of pain that’s held him until now. Still my hopes ride high-I’ll give that man his swamping fill of trouble,† Poseidon attacks Odysseus with a giant wave, and destroys his newly crafted raft. Odysseus survives with the help of the sea nymph Ino . The beautiful goddess Calypso who falls in love with Odysseus after he washes ashore on her island. Calypso, by means of enchantment, holds him prisoner there for seven years. Calypso used trickery and deceit to have possession over Odysseus. She was a beautiful nymph with a wonderful voice. Calypso uses these advantages to get what she wants. Calypso tries to make Odysseus her husband and asks him if he would want to be immortal by staying on the island with her. Odysseus tells her â€Å"I each day I long for home, long for the sight of home†¦. † In the end, the Gods overpower Calypso into letting him go, but she still demonstrates the god's idea as if it was her own. She tells him â€Å"O forlorn man, be still. Here you need grieve no more; you need not feel your life consumed here; I have pondered it, and I shall help you go†¦. In the end, she helps Odysseus after releasing him by providing him a raft and provisions to help him on his way without incident if the gods wish it. In conclusion, Odysseus, a mortal, is both helped and hindered by these supernatural beings. He encounters the wrath of Poseidon numerous times throughout his travels. He was held captive by Calypso on her island while longing for home. The Goddess Athena guided and protected hi m the most throughout his travels. Without the aid of these supernatural beings, the journey of Odysseus would not have been the brave, courageous, and risky adventure that it was.

Machiavelli – The Prince and Totalitarians

Another good example of this Marxist theory Is Joseph Stalin. Stalin used his military to rise to power. He killed countless people in order to come into authority and impose his beliefs on the state. Jewish virtual library explains, â€Å"Stalin consolidated his power base with the Great Purges against his political and ideological opponents, most notably the old cadres and the rank and file of the Bolshevik Party. † (Jewish Virtual Library, 1) Throughout the Great Purges Stalin imprisoned tortured and assassinated his enemies through his militaristic force.This Is a very clear display of Machiavellian theories because Machiavelli repeatedly states that military is the root of power and authority and he emphasizes that military should be used in order to rise to power. Another Machiavelli theory that justifies the actions of totalitarian rulers is the theory that it is more efficient to rule with cruelty and fear rather than love and fairness. Each of these totalitarian ruler s used this Ideology during their time as which is why people feared and respected him.BBC states, â€Å"Lenin demonstrated a hilling disregard for the sufferings of his fellow countrymen and mercilessly crushed any opposition. † (BBC, 1) This shows that Machiavellian theories did support Linen's actions because Machiavelli explains that it is better to for a â€Å"prince† to be feared rather than loved because love can come and go but the fear of pain is everlasting. Lenin proves this because he was feared and therefore people obeyed him. Another example of the use of cruelty is the cruel acts of Joseph Stalin.Stalin ruled with an iron fist and struck fear into peoples hearts. This fear is what drove hem to obey Stalin and conform to his will. Jewish Virtual Library states â€Å"It is believed that with the purges, forced famines, state terrorism, labor camps, and forced migrations, Stalin was responsible for the death of as many as 40 million people within the borde rs of the Soviet Union. † Jewish Virtual Library, 1) This follows Machiavellian theory because Stalin was excessively cruel to millions of people and was respected for a long period of time because of fear.Another theory that these totalitarians embody is the theory that a â€Å"prince† should ease their decisions on the well being of the state. For example: Karl Marx imposed his theory of communist-based Marxism on his state because he thought it was the best thing for the state. The Communist League explains â€Å"Marxist-Leninist accept the concept of social class put forward above, but hold that a person's social class is determined not by the amount of his wealth, but by the source of his income as determined by his relation to labor and to the means of production. (Marxism and Class, 1) Marx created this intricate system of classes in order to maintain order thin his state. Although it was not successful, Marx created this policy for the well being of the state, so that the state could flourish. This relates to Machiavellian theory because Marx did as Machiavelli advised. He had the well being of the state in mind throughout his time of ruling. Another ruler who followed Machiavellian theory on well being of the state was Vladimir Lenin. Lenin not only followed a Marxist trend in his state, but he also tried to improve his state's economy.BBC states, â€Å"He introduced the New Economic Policy, here a measure of private enterprise was again permitted, a policy that continued for several years after his death. † (BBC,I) Lenin introduced this policy in order to preserve the economy of his state. It lasted several years after his death, which means he was successful in doing so. Lenin laid out a structure for the state to thrive because he had the well being of the state in mind while making his decisions. This follows Machiavellian theory because Machiavelli said to make every decision based on the well being of the state.Although he w as cruel and used militaristic power, he was ultimately trying to better the state in his own way which is exactly what Machiavelli preaches. All in all, Karl Marx, Joseph Stalin, and Vladimir Lenin were embodiments of the theories Machiavelli introduced in â€Å"The Prince†. They ruled and based their states on militaristic power, they ruled their states through cruelty and pain over compassion and love, and kept the well being of the state in mind in every decision they made. Machiavellian theories Justified their actions in that they each very closely followed them.Karl Marx had a strong military and had the well being of the state in mind, throughout his time as ruler, and Vladimir Lenin had a strong military and also made sure to keep the well being of his state in mind. Although the states of these rulers were not very successful and resulted in the deaths of many people, they were supported by the Machiavellian theories. The lesson to be learned is that although their actions were supported by the Machiavellian theories, they caused severe damage and terror to the world and these theories should ultimately not be used in any type of modern government.

Love: The Universal Constant

Some say that the idea of love in modern terms differs conceptually from that of earlier periods. That argument is demonstrably false. Although love has been characterized In many different ways throughout the ages, the fundamental Idea remains constant. No matter the eccentric personalities love Is entitled to, love Is what It Is. From a literary point of view, whether one reads the tender longing of Shop, the unattainable desire of Patriarch, or the whimsical prose of Dickinson, the message of love– despite its myriad of forms–remains the same.The concept of love particular to the piece of writing is equally a study of psychology, sociology and anthropology as it is a literary endeavor. As readers of literature, we do not learn anything intrinsically controversial about love across eras, but rather translate the timeless message of the many facets of love into literature and interpret its significance. The idea (or theme) of love does not change from text to text rega rdless of era, but rather has new traits tacked on as time progresses.In her poem Rich-dethroned Immortal Aphrodite, Shop describes an insatiable desire or a woman, the pain of her refusal, and the dejected plea for release from the obsessive pursuit. Love struck, Shop begs Aphrodite to make the woman hers. Shop can only imagine the unbearable pain and sickness of a crushed heart if otherwise. In another poem, He looks to me to be in heaven, Shop overwhelms readers with feelings that resemble butterflies in the stomach.The narrator of the poem has fallen in love with someone who â€Å"makes the heart leap in my breast;' for watching you a moment, speech fails me,† My tongue is paralyzed, at once a light fire nuns beneath my skin, [my eyes are blinded, and my ears drumming. † The concept of obsessive love Is again Illustrated Is James Jockey's poem Arab. The mall character seeks to profess his love to a young girl whom he has clearly fallen head over heels for. The loves ick lad claims that â€Å"a flood from my heart seemed to pour itself out into mossy. ,' I thought little of the future. I did not know whether I would ever speak to her or not org if I spoke to her, how I could tell her of my confused adoration. ‘ But my body was like a harp/ and her words and gestures were eke fingers running upon the wires. † Similar to obsessive love, literature about love that is lost is just as timeless. The melancholy that pervades the text is palpable in Counted Culler's The Loss of Love. For example, the final lines: â€Å"l have no will to weep or sing,' No desire to pray or curse;' The loss of love Is a terrible thing,†Ã¢â‚¬Ëœ They Ill who say that death Is worse. Simultaneously, In Patriarch's Canceller, Patriarch mourns the loss of his Laura. The unmistakable and undeniable sensation of loss and hopelessness is evident in both laddered, uncensored my life/ is totally, that night and day it weeps J weary without a helm in stormy seas/ on a dubious course with no true guide. † Then, there was Shakespearean Sonnet 57 that conveyed the realization that a fool in love is no more than a willing slave. The willing unwillingness of the speaker's love makes one marvel at the truth of its depiction and at the tortured psychology which forces loved into the anguish of such impossible situations. Being your slave, what should I do but tend. ‘ Upon the hours and times of your desire? I have no precious time to spend,] Nor services to do, till you require. /†¦. But, like a sad slave, stay and think enough/ Save, where you are how happy you make those. ‘ So true a fool is love that in you will,] Though you do any thing, he thinks no ill. Almost half a millennium later, Emily Dickinson poem To lose thee moves readers with the same flooding emotions of a helpless lover. â€Å"To lose thee, sweeter than to gain/ All other hearts I knew. ‘ is true the drought is destitute/ But then I had the dew!The Caspian has its realms of sand,] Its other realm of sea;' Without the sterile perquisite/ No Caspian could be. So we see, love is an ageless universal constant. The powerful emotions invoked by love obviously reveal no discernible difference in the impact it has had, regardless of when the work was composed. Because there is a certain knowledge that love is enduring through the centuries with all its accompanying emotions and crossing of philosophical and religious boundaries, there is nothing really to be â€Å"conjured† about love, but only added factors that are â€Å"discovered. â€Å"

Ethical Leadership and Employee Behaivor Dissertation

Ethical Leadership and Employee Behaivor - Dissertation Example Furthermore, there is the pressing need to investigate all the manners in which ethical leadership tends to affect employee behavior. A number of steps have already been taken in order to promote ethical behavior such as the Sarbanes-Oxley Act. Though this is a step in the right direction but it cannot be termed as an end in itself. Instead, there is a constant need to explore the issue of ethical leadership and its impacts on employees to gauge methods to improve ethical conduct in organizations. This paper will attempt to analyze the dimensions of ethical leadership and its impacts on employee behavior as best as possible. Given the expansive nature of the topic, it is unrealistic to assume that all aspects and perspectives will be covered but this paper will attempt to delineate as much as possible. 2. Ethical Leadership Both ethics and leadership have been investigated for a very long time distinctly based on either normative or philosophical approaches. Results from these invest igations were traditionally used to decipher what leaders should do in order to bolster leadership. However, neither ethics nor leadership have been investigated on a strong scientific and social basis thus leading to fundamental gaps in understanding ethical leadership. ... cement and decision making also falls under the domain of ethical leadership (Brown, Trevino, & Harrison, 2005) (Trevino, Brown, & Hartman, 2003) (Trevino, Hartman, & Brown, 2000). In contrast philosophers have tried to define ethical leadership using normative perspectives by delineating how leadership ought to behave in organizational and other context (Ciulla, 2004). This approach to defining ethical leadership has narrowed down the focus of the subject. Instead the social scientific approach being pursued in this paper emphasizes describing ethical leadership, its antecedents as well as its consequences. Researchers have concluded for a long time that certain traits are more important to leadership than others. For example personal integrity has been linked with leadership effectiveness. Furthermore, perceived leader effectiveness has been linked to the perceptions of the leader’s character as per honesty, integrity and trustworthiness (Kirkpatrick & Locke, 1991) (Den Hart og, House, Hanges, Ruiz-Quintanilla, & Dorfman, 1999) (Posner & Schmidt, 1992) (Kouzes & Posner, 1993). In addition to these traits cognitive trust is also associated with effective leadership styles (Dirks & Ferrin, 2002). In this context cognitive trust has been defined as being composed of exercise of care in work, dependability and professionalism (McAllister, 1995). This concept has been used by Trevino et al (2000, 2003) in order to research what ethical leadership means to proximate observers of leaders. The research utilized structured interviews with twenty ethics or compliance officers as well as twenty senior executives. The respondents were asked to think of an ethical leader they knew about and to answer a broad survey that queried the motives, characteristics and behavior model of

In his article, Lorenzen argues that with the increased demand for information technology especially during research, academic institutions should adopt strategic planning in their departments including libraries. This article indicates that for any organization to put in place effective strategies, it must undertake an analysis of the environment under which it operates. This can be done by the use of various frameworks such as SWOT, PESTEL, and Porters five among others. In this article, Priyanka Sangani indicates that companies in the modern times should ensure that employees take charge in strategic planning. This is not only a way of creating strong bond within an organization, but it also makes the workers to feel motivated. In this article, Arshdeep Sehgal covers the various strategies that Chief Financial Officers globally have adopted as the result of recent economic downturn worldwide. Notably, most of the CFOs spend most of their time in strategic planning as compared to the past years. This article defines strategic planning by the use of two myths. First myth according to the author is that strategic planning covers issues like SWOT analysis, value chain analysis, and competitive positioning among others. The second myth indicates that it entails making bold and risky bets by the use of available resources and opportunities. This article covers the eight-step change model that John Kotter, a renowned change expert established including creating urgency, forming a powerful coalition, creating a vision for change, communicating the vision, eliminating the obstacles, creation of short term wins, building on the change and adopting the change in the corporate culture. In this article, Kotter indicates that for an organization to experience a

Creating Healing - Assignment Example With this kind of trend, it is not easy to remain healthy (Malliori, 2010) One Saturday afternoon, I decided to visit a conservation park and take some time alone to mediate over things that had been happening and how I could deal with them. As I walked through, I reached a certain section which was basically inhabited by the monkeys. I stood from a distance and watched them go about their activities. There were four monkeys which had young ones. One of them sat peacefully on one branch feeding the sibling. On the other hand, the others jumped from one branch to the other. Occasionally, those with young ones would stop to feed them but only for a few minutes before they joined the rest in jumping from branch to branch. In all this, one was able to keep its position for a long time and feed and care for the young one. The observation made me wonder if this was what was happening to me. I found it very similar to my situation. Every time when I seemed to be having a lot of responsibilities at work and at home, my mind always wanders as I keep thinking about how I will do all of them. I keep on being distracted with my concentration jumping from one subject to the other just like the monkeys were jumping form one branch to the next. With such shifting concentration, it is usually hard to accomplish responsibilities and these impacts directly on one’s overall wellbeing (Ellen, 2010). According to Dossey and Keegan (2013), for one to say that he has optimal health, he must be able to balance all the aspects of his life as a person. This is something I was not able to do since while at work, I kept thinking about the responsibilities I had to fulfil at home. While at home I also thought about the unfinished work that I had. I believe I can do this by taming my mind from wandering so as to calm down and concentrate on a single task. The situation raised is very much applicable to case three that has

Success Essay Example | Topics and Well Written Essays - 500 words - 2

Success - Essay Example The definition of success comprises of elements including happiness, health and conquering hardships. One way of identifying how successful an individual is by identifying the level of happiness experienced by that individual. Happiness can be attained through various means, while some people may find happiness in helping others and on the other hand some may experience happiness due to attaining huge amount of wealth and a flashy lifestyle. Individuals who tend to attain happiness through materialistic gains tend to experience happiness for a shorter period of time. While individuals who gain happiness by helping others may experience happiness for a longer period of time. This means that success is short lived if human beings are happy due to their materialistic gains and success is prolonged if that attain happiness through helping others. Another factor that should be taken into account while defining success is the health of a particular individual. Health is very important for an individual to benefit from all of his achievements. An individual may not feel successful if he/she or his/her family members are not healthy. An individual works hard with the aim of gaining wealth in order to provide joy and a comfortable life to themselves and their family members. If an individual or their family members can not enjoy that wealth, an individual may feel unsuccessful. Success can even be defined in terms of an individual’s ability to conquer the obstacles that they face in their lives. An individual who does not work hard in order to earn money and uses shortcuts to attain wealth may be less satisfied with the wealth as compared to an individual who has worked hard and dedicated his/her life for the achievement of aims and objectives. The success that individual gains by facing difficulties are in life provides him with something to be proud of and to cherish. Such success provides an individual with peace of

How Would You Value a Firm That You Were Trying To Purchase Research Paper

How Would You Value a Firm That You Were Trying To Purchase - Research Paper Example Holton and Bates 2009, elucidates that there are a number of methods through which a potential purchaser of a particular firm may apply in an effort to realize the value of that firm. The methods may include: Free Cash Flow Methods, Asset-Based Methods, Option-Based Valuation method, and the method of using Comparables, These tools or methods of valuations would in return assist the potential purchaser of the firm to analyze and make an informed purchasing choice. Discussion To begin with, the asset-based method can be efficiently used be an intending purchaser to value a give firm. This method reveals the book value of a firm’s equity. In simpler terms, the asset based method shows the asset value of a firm or a company, less the debts of the firm. According to Strauss, 2011, a potential purchaser of a firm may find this method of valuation helpful since a company’s equity is all that a firm can be left with in an instance where it suddenly halt its selling its product s or making money. This equity may be current assets, shareholders equity, and cash as tangible things, as well as brand name and management as intangible qualities. The shortcomings of this method however is that there are some hidden assets that cannot be revealed. This may happen in instances where a piece of a firm land was purchased years ago and the value of that land has been kept as it was despite the appreciation that has dramatically taken place. Another method may be used to value a firm is by using comparables. This method is one of the most common means through which a company valuation is done by simply using the earnings that a company gets. The earnings of a firm sometimes referred to as the net profit or net income can be said to be the amount of money that a firm is left with after it has paid all its bills or debts. In most cases, earning of a firm is measured according to the earnings per share. Earnings per share can be calculated by dividing the amount of earni ng a firm reports by the outstanding number of shares the firm has. Even though this method may be helpful to an individual intending to purchase a given firm, it falls short of other aspects of valuing a firm such as the firm assets which are an importance aspect of valuation in any business (Mayo 2010) Further, free cash flow method may be used in an attempt to value the worth of a given firm. Even though most of the individual investors are not conversant with cash flow, this method is commonly used for valuation of both private and public firms especially by the bankers. Cash flow can be described as the company’s earnings before taxes, interest amortization and depreciation. This method may however be ineffective in valuing a firm worth and the actual business earnings since the taxes and other costs are not subtracted from the general earning. Taxes payable by a given firm may vary depending on the laws governing taxation in a particular financial year and even though t he earnings of a given firm may be hefty the amount of taxes may be large thus the secondary costs or company’s profits may be uncertain. Finally, a person may opt to use the option based method to value the worth of a firm before purchasing that firm. There are several other techniques of firm valuation as aforementioned

Philosophy and the Examined Life Essay Example | Topics and Well Written Essays - 750 words

Philosophy and the Examined Life - Essay Example It is evidently clear from the discussion that a person who lives an examined life should seek genuine knowledge and not mere victory over his opponents since the knowledge acquired is the one, which is important. This is clearly elaborated in Socrates first dialogue with Euthyphro when he informs him that he is pursuing the case of murder involving his father who had subjected one of his workers to death. Euthyphro argues that justice should prevail regardless of the relations that exist since moral duty must prevail. This argument makes Socrates ask him to define his understanding of moral duty where he responds by saying that moral duty is anything that is pious. He goes on to question him on his understanding of pious and is not able to define clearly the place of gods in moral duty. This kind of conversation shows that a person should seek the truth and he should not be motivated by anything else other than the truth. A sound development of a philosophical attitude enables one t o cultivate this habit of only seeking authentic knowledge. The philosophical approach enables a person to develop a sense of clear reasoning in all circumstances regardless of the consequences associated with the reasoning. Socrates in his dialogue â€Å"apology† after the jury has found him guilty of the accusations made against him goes on with his sound reasoning. He responds by clearly expressing his sense of reasoning, which was not evident in the rest including the court and his accuser Mellitus. Philosophy influences the actions of people in any society as seen in the life of Socrates who was able to influence Euthyphro when they met shortly before going to the court where he had been charged. Socrates was able to question him on his understanding of piety and justice ultimately influencing him to change his own beliefs. This kind of influence makes one understand the universe better because it prompts him to ask questions rather than just believing everything the way it is presented. An intelligent person who has a philosophical attitude will not merely study various disciplines but will excel and probably come up with innovations, which are very fundamental in the life of a man.

Benefits And Costs Of Using Common Currency In Greece, Germany And Research Paper

Benefits And Costs Of Using Common Currency In Greece, Germany And Eurozone - Research Paper Example 14). As a result of reduced transaction costs, Eurozone nations expected a thirty billion dollar annual savings (The Euro, the European Central Bank, p. 154). Directly as result of eliminating exchange of currencies, the exchange rate volatility was also removed. These exchange rate fluctuations make the trade between countries more risky; because if one currency devalues in relation to other, the marketer of the depreciated currency will be affected by getting less than what his product is worth. Or conversely the buyer of depreciated currency may require paying more than what he originally contracted for (Eudey, pp. 14-15). Exchange rate rish is thus another form of transaction cost which was avoided. Another major benefit of Euro as the common currency was the avoidance of speculation. Before the introduction of Euro, speculation used to greatly occur throughout the Europe. Whenever a currency was thought to be devalued in near future, people used to sell all their holdings in tha t currency. The only solution to the problem of speculation was keeping the interest rates as high as possible to keep the people interest in the currency. These high interest rates were bad for the economy and hindered economic progress in Europe during 90s (Eudey, pp. 15, 16). Adoption of Euro as a common currency thus removed speculation and economies of the member countries could develop and flourish easily without the disadvantages of higher interest rates. Euro also does away with the problem of competitive devaluation of currency among the member nations. Before the era of Euro, European nations used to devalue their currency to increase the exports. Inflation was a direct result of this devalution (Eudey, p. 15). The adoption of common currency did in fact come with many costs as well. The first and the foremost disadvantage of adopting common currency by the Eurozone countries was that by accepting Euro as national currency they surrendered their right to adopt and change t heir monetary and economic policies to suit their domestic conditions (The Euro: Expect, pp. 123). There was another big cost of not being able to adjust the exchange rates between trading countries to eliminate the economic falloffs of individual countries. Even after the adoption of common currency and a unit monetary policy throughout the Eurozone and its many benefits, there is no surety that some member country may not go in recession; and this was the main concern for all the countries. If at any time one country goes into recession, it cannot alter the individual monetary policy and as a result the only option left is to wait, because a change in the monetary policy of all the nations would adversely affect more countries than benefit the country in recession (The Euro, the European Central Bank, pp. 157). Despite of this, the idea of creating a common currency was that by tying many European nations through a common currency, the business cycle of all countries will soon be closely linked to each other and very soon would there be no possibility of recession in one country while stability in other (The Euro: Expectations and Performance, p. 123). However, changes in individual Fiscal policies was allowed. Benefits and Costs of common currency in Greece Recently there has been a debt crisis in Greece and other Eurozone countries which has jeopardized the likelihood of continuing with the Euro. Especially Greece is highly considering to quit the Euro and reverting back to its national currency Drachma. The debt crisis is raising a lot of questions and discussions about the potential advantages and

Freeway Congestion Essay The economy of a country may be determined by several factors . the growth of country’s wealth is coupled to factors such as the people population, availability of natural resources, their proper usage and general environmental management. During early time of our fore father, people enjoyed better environment due to low populations of all sort things. Peoples’ population was low and many of them lived in remote areas. Occupational space was never an issue to think of, as there was plenty of land available for any particular use. They preferred rural areas as most of them were gatherers and pastoralists. While others were substance farmers and hunters, they had the freedom to use select the site to carry out any activity of their wish anywhere. Land ownership was generally belonging to the community but not an individual as it is nowadays. The present system of individual land ownership has brought a lot of discrepancies in the distribution of people populations, infrastructure and other community amenities of paramount importance. Due to above reason different kinds of congestion has resulted leading to stresses and tensions in today’s global world. This has leads me to think of economic urban areas in term traffic congestions. (Schrank and Lomas, 2002) The interdependence between transportation and land use has long before been recognized m. Land use strongly affects transportation patterns, and the properties of the transportation network strongly affect the land use. This is well understood in a homocentric city with only commuting travel of the central business district. Most cities have become increasingly polycentric and job locations increasingly dispersed. (Anas and Small, 1980) It is also evident that noncom muting trips have become increasing important with the choice of residential location less strongly tied to workplace location. So these changes in land use are likely to continue to affect traffic volumes and patterns even more so. It is certain that the problem of traffic jams is so often to a point of describing it as a curse of the modern life. It is obvious that people must interact with one another through social life and that they have to travel long distances for purposes of business transactions. Motor vehicle transportation is one of the common methods used all over the world. Many major cities are fed and connected to each other by means of roads . so roads makes a very useful means of communication. People and cargo transport is a usual activity. Although this has proved very valuable to many developing and developed countries, it has also turned out to be one of the most embarrassing ways of travel and cargo transportation means. This is exactly due to traffic congestion in major towns and cities; which are also over burdened with all other types of congestions. Traffic congestion result out to be a miserable waste of time . Traffic congestion is the build up of traffic preventing efficient movement . it is one of the most significant problems faced in modern cities today. The products of this are other major problems such as air pollution, noise pollution, visual pollution, parking problems, destruction houses and increased risks of vehicle accidents. (Schrank and Lomas, 2002) It is not unreasonable to call up severe visions of traffic jam by the year 2050 with angry motorists hooting their horns, distressed not to be even later in picking children from school or making critical appointments in the developed countries. Many people living in developed countries continues to buy more vehicles, hence household vehicle ownership rates continue to rise evenly (Hu and Young 1994). The trend of continuous increase in incomes and falling costs of car operation, vehicle miles traveled per licensed driver continue their seemingly inexorable rise. Several transportation institutes have reported alarming increases in the traffic congestion in metropolitan areas over the last two decades (schrank and Lomas, 2002). The average number of hour that most people have suffered in a traffic jam is seven. At the same time, the travel hours to work have been increasing too, nonetheless dramatically. However, there are equal countertrends, such as rising of urban street surfaces and traffic management which includes the synchronization of traffic light, improved urban freeways and highways being added and expanded, production of new automobiles with advanced technologies not forgetting the increasing proportion of urban travel from one suburban location to another. The above trend is being offset or balances out due to increase in travel under severe congestion conditions. (Schrank and Lomas, 2002) The traffic congestion situation looks to a forgotten or a blind eye sight in most experts and this raises a weak presumption that the new improvement being under taken are leading to traffics moving more faster than twenty years ago. The fact remains that the future holds worse urban traffic congestions hence there is great need to find ways of alleviating urban traffic congestions. This can be thought in many ways as a cost that is voluntarily incurred in order to enjoy the higher incomes, amenities, increasing variety of consumer goods, enlarged scope for social interaction, and generally more stimulating and vibrant lifestyles the living in cities provides. Due to fully inefficient economy of many countries, which entails among other thing the efficient pricing and provision of transportation, traffic congestion is of paramount importance than the increase the price of any other commodity competitive in the market. Urbane economy should therefore in any way be ignored, but people should be focused out the failure to charge drivers for the external congestions they impose. Several traffic controls have been put in place for which some have worked well in some countries while other are void. Land use controls on a macro scale have been practiced in Northern Europe; this has proved very effectively in reducing the overall travel and congestion . it is noted that land use control on micro scale being practiced in the U. S where by residential are separated from non residential land uses, encourages car travel while mixing land uses at local level. (Schrank and Lomas, 2002) Another method that can be applied to the reduction of traffic congestion is the application of mass transportation mostly by focusing on cars. Many personal cars within the cities carry individual drivers with all the other seats remaining empty. this is quite uneconomical because of fuel consumption and the space utilization on the roads (Mohring, 1972). there is need to explore basic economic principles of mass transit that are likely effective in lowering transit cost function and traffic jams. This is one major factors leading congestion because people have valued comfort more than time and cost. Economists should come up with ways that consider vehicle size, comfort, acceleration of buses and subway cars, the length of subway trains and station platforms, the service frequency and density of buses and subway trains, procedures to mitigate bus grouping, expedite passenger entry and exit reducing the external marginal congestions imposed by buses on cars, and repair and maintenance rolling stock together with the design of fare collection systems. Pedestrian are nevertheless left out as they really cause and act as obstacle during road crossing. it is very important to accord the due respect to pedestrian at the zebra crossing . but such crossing areas bring inconveniencies to drivers hence causing jams. Traffic congestion will be alleviated if pedestrians and travelers’ walkways would be provided with fly over instead of zebra crossing. Thus pedestrian –car congestion should be given anew design and construction. Many developed countries suffer from traffic congestion due to restriction of shopping hours. such policies restring shopping periods should be ban to allow more shopping time and reduce congestion this may seem less conceivable as result oriented of target but many people take one shopping trip rather than having separate shopping trip. Liberalized shopping has desirable outcomes. (Schrank and Lomas, 2002) Considering that often accidents do occur, they are not only costly to the direct damage but also for the non recurrent congestion they induce. The involvement of engineers on the construction of roads is necessary to include economists. An Example of work done by Newbery (1988) gives valuable contribution of freeway and high way design ,construction, and maintenance, if sound cost- benefit analysis were practiced in all aspects of urban road engineering, substantial cost saving would be achieved . Urban transport economists make valuable contributions through analyze of sound cost benefit by state and local government. In conclusion, traffic congestion is a major concern in modern society . it affects our environment with environmental pollutions through the emission of fumes. People are put at risk from the danger of excessive vehicles which results from increased car ownership and commuting to fat residential places. Generally the solution to traffic problems is by widening the roads, creation of bypasses in the inner ring roads and outer ring roads . creation of more motorways and bus lanes to provide more space. Another way of improving the means is banning personal vehicles through imposing heavy levies on fuels and import duty. This can also be incorporated by banning cars from the central business districts and overcharging those with special cases on parking places. Reference: Abbott, J.

Bus reservation Essay Example for Free

Bus reservation Essay The purpose of this report is to explain detailed description of Bus Reservation System. It will explain the aim of the project, the limitations of the system, interfaces of the system, what the project will do, what kind of future works may be done. 1. 2 Maintenance An accredited bus operator may demonstrate compliance with this requirement by: †¢ accessing manufacturer’s specifications and/or any other reference material deemed appropriate for the age, make and model of the buses in the accredited bus operator’s fleet †¢ developing and implementing service schedules 1. 3 Objectives This project is based on a scenario. In this scenario, customer wants to know bus services with their time and date when he decided to travel. He can do this by a phone call or going to agency. In both situations, he will meet the employee who work at the agency and get information about services, its departure time, departure date, destination time, suitable seats etc. If he decides to reserve a ticket, then employee will take some personnel information from customer and will reserve a seat that customer selected. Travelling is a large growing business in Turkey and other countries also. It becomes very difficult to keep bus services records and customer information. Our project will be useful in the Bus Reservation System. This project’s aim is to satisfy a facility to reserve seats, cancellation of seats and different types of enquiry like seat status, service enquiry and service time. 1. 4 Limitations This project has some limitations. Firstly, services are only between Laoag-Manila and Manila-Laoag. Secondly, each day there are three services for each direction at 9. 00 am, 1. 00 pm and 8. 00 pm. Thirdly, ticket can be reserved by an employee who works at the agency. Namely; customer cannot reserve a ticket. Finally, man and woman cannot seat side by side if they do not know each other. 1. 5 Problem Customers have to go to the counter to buy bus ticket or ask for bus schedule. Customers need to pay cash when they buy bus tickets and sometimes needs to queue up for hours to get bus tickets. Besides that, customers are also not allowed to buy bus tickets through telephone because the bus companys telephone line is always busy. II. Flowchart III. Screenshots This shows the title of our system which is the Reservation System. As we can see we put the name of the programmer. Then press any key to continue the program. This data shows to fix the first few errors or warnings, since they may be causing all the rest. A compiler warning indicates youve done something bad, but not something that will prevent the code from being compiled. You should fix whatever causes warnings since they often lead to other problems that will not be so easy to find. Compiler messages usually list the file and line number where a problem occurs. Nonetheless, errors often occur on the lines prior to what the error message lists. Especially check the line immediately preceding where the error message indicates. Finally, note that some compilers may choose to call something an error while others may just call it a warning or not complain at all. As we can see we have no warnings and errors. After the welcome form then system opens the login form. Here user has to enter valid user id and password. There are shown as below.. This shows the main menu where you can choose your reservation. This shows the different choices of bus, we have deluxe, air-conditioned bus and ordinary bus. You can also choose the time you want.

The Circulatory System Functions Of The Heart Physical Education Essay

The Circulatory System Functions Of The Heart Physical Education Essay Circulatory System is the combined function of the heart, blood, and blood vessels to transport oxygen and nutrients to organs and tissues throughout the body and carry away waste products. The circulatory system increases the flow of blood to meet increased energy demands during exercise and regulates body temperature. Also, when foreign substances or organisms invade the body, the circulatory system quickly sends disease-fighting elements of the immune system, such as white blood cells and antibodies, to places under attack. In the case of injury or bleeding, the circulatory system sends clotting cells and proteins to the affected site, which quickly stop bleeding and promote healing. The heart, blood, and blood vessels are the three main elements that make up the circulatory system. The heart is the engine of the circulatory system. It is divided into four chambers, the right atrium, the right ventricle, the left atrium, and the left ventricle. The walls of these chambers are made of a muscle called myocardium, which contracts to pump blood. The pumping action of the heart occurs in two stages for each heartbeat. Diastole, when the heart is at rest, and systole, when the heart contracts to pump deoxygenated blood toward the lungs and oxygenated blood to the body. There are typically about 60 to 90 beats per minute. If the heart stops pumping, death usually occurs within four to five minutes. Blood consists of three types of cells, red blood cells that carry oxygen, disease-fighting white blood cells, and blood-clotting platelets, which are all carried through plasma. Plasma is yellowish and consists of water, salts, proteins, vitamins, minerals, hormones, dissolved gases, and fats. Three types of blood vessels make a network of tubes throughout the body. Arteries carry blood away from the heart, and veins carry it toward the heart. Capillaries are tiny links between the arteries and the veins where oxygen and nutrients spread to body tissues. The inner layer of blood vessels is lined with cells that create a smooth passage for the transfer of blood. This inner layer is surrounded by connective tissue and smooth muscle that help the blood vessel to expand or contract. Blood vessels expand during exercise to meet the increased demand for blood and to cool the body. Blood vessels contract after an injury to reduce bleeding and also to conserve body heat. Arteries have thicker walls than veins so they can withstand the pressure of blood being pumped from the heart. Blood in the veins is at a lower pressure, so veins have one-way valves to prevent blood from flowing backwards away from the heart. Capillaries, which are the smallest of blood vessels, are only visible by microscope. The arteries, veins, and capillaries are divided into two systems of circulation, systemic and pulmonary. The systemic circulation carries oxygenated blood from the heart to all the tissues in the body except the lungs and returns deoxygenated blood carrying waste products, such as carbon dioxide, back to the heart. The pulmonary circulation carries this blood from the heart to the lungs. In the lungs, the blood releases its carbon dioxide and absorbs oxygen. The oxygenated blood then returns to the heart before transferring to the systemic circulation. The heart gets rid of oxygen-rich blood under high pressure out of the left ventricle, through the aorta. Smaller arteries branch off from the aorta, leading to various parts of the body. These smaller arteries in turn branch out into even smaller arteries, called arterioles. Branches of arterioles become progressively smaller in diameter, eventually forming the capillaries. Once blood reaches the capillary level, blood pressure is greatly reduced. Capillaries have extremely thin walls that allow dissolved oxygen and nutrients from the blood to become a fluid, called the interstitial fluid, that fills the gaps between the cells of tissues or organs. The dissolved oxygen and nutrients then enter the cells from the interstitial fluid by diffusion across the cell membranes. Meanwhile, carbon dioxide and other wastes leave the cell, diffuse through the interstitial fluid, cross the capillary walls, and enter the blood. In this way, the blood delivers nutrients and removes wastes without leaving the capillary tube. After delivering oxygen to tissues and absorbing wastes, the deoxygenated blood in the capillaries then starts to return to the heart. The capillaries merge to form tiny veins, called venules. These veins in turn join together to form progressively larger veins. Ultimately, the veins converge into two large veins, the inferior vena cava, that brings blood from the lower half of the body, and the superior vena cava, that brings blood from the upper half. Both of these two large veins join at the right atrium of the heart. The circulatory system plays an important role in controlling body temperature. During exercise, working muscles generate heat. The blood supplying the muscles with oxygen and nutrients absorbs much of this heat and carries it away to other parts of the body. If the body gets too warm, blood vessels near the skin enlarge to disperse excess heat outward through the skin. In cold environments, these blood vessels constrict to retain heat. The pressure generated by the pumping action of the heart propels the blood to the arteries. Blood pressure, for instance, enables a person to rise quickly from a horizontal position without blood pooling in the legs, which would cause fainting from deprivation of blood to the brain. Normal blood pressure is regulated by a number of factors, such as the contraction of the heart, the elasticity of arterial walls, blood volume, and resistance of blood vessels to the passage of blood. Blood pressure is measured during systole, the active pumping phase of the heart, and diastole, the resting phase between heartbeats. Blood pressure varies between individuals and even during the normal course of a day in response to emotion, exertion, sleep, and other physical and mental changes. The average normal blood pressure is about 120/80 mm Hg. Higher blood pressures that are sustained over a long period of time may indicate hypertension, a damaging circulatory condition. Lower blood pressures cou ld signal shock from heart failure, dehydration, internal bleeding, or blood loss.

Providing proper education and appropriate training are also two important strategies to increase the end user acceptance rate. The organization is also going through a drastic change, with changes in the way businesses are conducted, the organization being restructured, and job responsibilities being redefined.

Standardized Tests :: Standardized Testing Essays

  Ã‚  Ã‚  Ã‚  Ã‚     Ã‚  Ã‚  Ã‚  Ã‚  Standardized tests are very common throughout the United States. They are used to measure students’ academic performances in school. These tests vary from state to state in all grade levels. However, these tests are believed to be biased towards those students who come from higher-class neighborhoods, simply because they have more educational resources. â€Å"The absence of standards virtually guarantees stratified resources and access to knowledge, based upon income, color of skin, and the community and neighborhood in which one lives† (French, 2003). The resources in the suburban areas differ from those in the urban areas, because of the gap within the difference of incomes. Families living in suburban neighborhoods have a bigger income, which enables them to have more resources than those living in urban neighborhoods. Most educational resources come from taxes, which plays a big part in the gap between urban and suburban neighborhoods.   Ã‚  Ã‚  Ã‚  Ã‚  This gap causes a disadvantage to those individuals living in lower class neighborhoods, because they do not see or have as many resources as those living in the suburbs. Because of the lack of resources that are provided to those living in the lower-class neighborhoods they are not as prepared for the standardized tests as their higher-class counterparts. These standardized tests are seeing new standards every couple of years or so. Some of the new standards include, students receiving a certain score in the tested subject areas in order to refrain from failing and being retained in the same grade, or even going to summer school just to be promoted. Are these standards helping or hurting?   Ã‚  Ã‚  Ã‚  Ã‚  It is hard to say whether these tests are efficient in assessing a student’s knowledge. There have been studies done that shows how students perform contributes to a number of factors. Students are individuals just as adults and can easily slip up on a test, just as many adults have done because of numerous reasons. They suffer from stress, lack of sleep, how they are feeling, whether they ate, and many other reasons. â€Å"These influences most dramatically affect low-income students and students of color† (French, 2003). From the rise of immigration there have been tests (IQ and Stanford-Binet) that were used to sort and track students based on race and income. According to a study it has been concluded that these tests will continue to hinder the ability of Black and Latino students to graduate from high school (Orfield and Wald, 2000; Haney, 1999; McNeil, 2000).

The Failure of the War on Drugs Essay -- Critical Thinking Essays

In the early 1980s, policymakers and law enforcement officials stepped up efforts to combat the trafficking and use of illicit drugs. This was the popular â€Å"war on drugs,† hailed by conservatives and liberals alike as a means to restore order and hope to communities and families plagued by anti-social or self-destructive pathologies. By reducing illicit drug use, many claimed, the drug war would significantly reduce the rate of serious nondrug crimes - robbery, assault, rape, homicide and the like. Has the drug war succeeded in doing so? In Illicit Drugs and Crime, Bruce L. Benson and David W. Rasmussen (Professors of Economics, Florida State University, and Research Fellows, the Independent Institute), reply with a resounding no. Not only has the drug war failed to reduce violent and property crime but, by shifting criminal justice resources (the police, courts, prisons, probation officers, etc.) away from directly fighting such crime, the drug war has put citizens’ lives and property at greater risk, Benson and Rasmussen contend. â€Å"Getting tough on drugs inevitably translates into getting soft on nondrug crime,† they write. â€Å"When a decision is made to wage a ‘war on drugs,’ other things that criminal justice resources might do have to be sacrificed.† To support this conclusion, Benson and Rasmussen compare data on drug law enforcement and crime trends between states, and debunk numerous misconceptions about drug use and criminality. One of the most prevalent misconceptions, Benson and Rasmussen, contend is the notion that a large percentage of drug users commit nondrug crimes, what might be called the â€Å"drugs-cause-crime† assumption implicit in the government’s drug-war strategy. If true, then an effective crackdown on ... ...easy† to obtain rose by about 20 percent. This failure is due in large part, Benson and Rasmussen explain, to drug entrepreneurs’ adoption of new production techniques, new products, and new marketing strategies in response to greater law enforcement. Their â€Å"innovations† include lengthening the drug distribution chain and using younger drug pushers and runners (to reduce the risk of arrest and punishment), increasing domestic drug production (to avoid the risk of seizure at the border), smuggling into the country less marijuana and more cocaine (which is harder to detect), development of â€Å"crack† cocaine (a low-cost substitute for higher priced powdered cocaine and for marijuana, which the drug war made harder to obtain), and development of drugs with greater potency (because they are less bulky and because punishment is based on a drug’s weight, not its potency).

Public Police and Private Security Essay

Abstract         Public police and private security agencies will hardly find a compromise. Public police votes for limitation of private security rights. Private security becomes more popular with the increasing criminalization of the society. In reality, the objectives of public police and private security significantly differ.       The increasing popularity of private security agencies has raised substantial concern among the public police officers. The objectives of public police and private security differ, but public police agencies fear that private security will bury traditional policing standards, and will replace the major policies objectives and responsibilities.          In the general structure of public policing responsibilities, private security guards traditionally fulfill â€Å"supporting roles†. By hiring contractors, some federal agencies save up to 50 percent of their traditional expenditures. â€Å"One firm provides security for six major public transit systems around the country, transports prisoners, maintains booking and security for a juvenile assessment center, and supplies security for court houses in 40 states† (Youngs, 2004). Although private security agencies possess full range of policing equipment, personnel, and opportunities, such agencies are permanently restricted from fully participating in public policing. Potentially, private security and public policing could have similar objectives, but public policing remains purely a state structure. Public police agencies use private security firms to concentrate on their major tasks. In many aspects, these strategies remind outsourcing principles, which are often employed business. In Ontario, private security was given some freedom â€Å"to observe, report, and deter [†¦] elsewhere private security companies are offering quasi-police services in low-income housing projects† (Harman, 2000). Although private security and public policing could effectively combine their efforts, and work for the decrease of criminalization in the country, public policing insists on the fact that public police and private security cannot follow the same objectives.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Public policing continues fulfilling its â€Å"traditional crime-fighting duties. Private security carry out their mission of protecting their companies or clients’ people, property, and information, while at the same time serving the homeland security objectives† (COPS, 2004). Private security and public policing are still too far from joining their efforts and objectives for the benefit of criminal situation in society. References COPS. (2004).

Martha Stewart: Not Such a Good Thing Essay

1. What issues did Martha Stewart, Bacanovic, and Faneuil miss in making their decisions about selling the ImClone stock in their conduct following the sales? Apply the models and make a list of suggested questions they could have asked that might have affected their decisions. I do not feel any of them were thinking about any consequences! Why was this small amount of money so important to them, especially Ms. Stewart, who was a multi- billionaire at the time? It is clear that they weren’t concerned at all about outcome and just went ahead with their scheme that they truly thought they could pull off without getting caught. 2. Was selling the shares illegal? If selling the shares was not illegal, was it unethical? Selling shares are not illegal; it’s all part of the stock market. However, when you have advanced knowledge like this case, it is border-line and extremely unethical. She was thinking only of herself and the profits she’d make, and not considering the company and other stockholders at all. I would go as far as calling it heartless and greedy! 3. What do we learn about long-term consequences from Ms. Stewart’s conduct and case? Having too much money can turn a person evil. Martha was a multi-billionaire, and why she cared about a couple hundred thousand is crazy. Not only did she serve jail time, lose respect and money, her stock has decreased The public now sees that she is not trustworthy, because she admitted to obstruction of justice and making false statements to federal investigators.

Perception of Various Performance Criteria by Stakeholders in the Construction Sector in Hong Kong

Construction Management and Economics (April 2010) 28, 377–391 Perception of various performance criteria by stakeholders in the construction sector in Hong Kong IVAN K. W. LAI1* and FRANKIE K. S. LAM2 1 2 Faculty of Management and Administration, Macau University of Science and Technology, Macau International Graduate School of Business, University of South Australia, Adelaide, Australia Taylor and Francis Received 8 March 2009; accepted 1 December 2009 10. 1080/01446190903521515 All construction projects in Hong Kong have in common a cast of key contract participants, consisting of clients, consultants (designers) and contractors. The aim of this research is to examine, from different points of view, these practitioners in regard to the importance of perceived performance criteria and their respective performance outcomes in a construction project. A research model is structured based on nine performance criteria and their respective performances. The data were collected from 324 practitioners who have participated in construction projects in Hong Kong. One-way analysis of variance (ANOVA) and repeated measures ANOVA are used to analyse the data. The relative importance of nine performance criteria and their performances are measured. Timely completion of the project is the most important performance criterion, followed by profit, environmental protection and quality. There are differences in the importance of the performance criteria with respect to performance. The differences in the perceptions of performance that are identified are: (i) among different practitioners in a construction project; (ii) due to different project types; and (iii) between different functional roles in the partnering organizations. In order to further understand the importance of the performance criteria with respect to performance, the status quo of roject partnering and congeniality problems in the construction industry is reviewed. It is intended to stimulate interest in the further exploration of solutions to improve the overall performance of the construction industry in Hong Kong. Keywords: Performance improvement, performance evaluation, partnering, supplier relationship, performance criteria. Introduction At the beginning of con struction projects, various targets are set as ‘performance criteria’ to be achieved among the key contract participants, consisting of clients, consultants (designers) and contractors. However, different participants have their own perceptions of various performance criteria, and they perform differently according to their perceptions. The aim of this study is to examine, from different points of view, these participants in regard to the importance of the perceived performance criteria and their respective performance outcomes in a construction project. The differences between the levels of importance of the performance criteria and their respective performance outcomes represent areas for the improvement of performance, which these participants should address. Author for correspondence. E-mail: [email  protected] edu. mo In the present study, nine specific performance criteria are used; they are: (1) profit; (2) time; (3) no claims or contractual disputes; (4) job satisfaction; (5) quality; (6) safety; (7) environment; (8) generation of innovative ideas; and (9) effectiveness. A research model was formulated to test the significant difference between these perfo rmance criteria with respect to their performance. There are also tests available to assess the performance of these performance criteria from the perspective of the respondents in different roles (i. . clients, consultants and main contractors); the types of construction projects (i. e. government, public/private utility and private development); and different functional roles of the staff within the organization (i. e. managerial, frontline supervisory and consultancy staff). This research was conducted through a questionnaire survey with construction practitioners in Construction Management and Economics ISSN 0144-6193 print/ISSN 1466-433X online  © 2010 Taylor & Francis http://www. informaworld. com DOI: 10. 1080/01446190903521515 378 Hong Kong. The overall discussion that follows is based on the results of the statistical analysis of the performance criteria and their respective performances as well as the major differences between the different perspectives of the participants. There are significant differences between the performance criteria with respect to performance, and conclusions are drawn from patterns noted in these results. This study indicates some areas for the improvement of performance. The limitations of this research and further research opportunities will be identified. Lai and Lam eam considers to be relevant in the pursuit of successful project delivery (Swan and Khalfan, 2007). Construction delays not only result in cost overruns and poor quality, but lead to increased disputes (Al-Khalil and Al-Ghafly, 1999). Odeh and Battaineh (2002) observed that most claims cases are related to the time of the project delivery. No claims or contractual disputes. It has been observed that the adaptive ability to man age changes without unnecessary claims is often critical in the routine assessment of subcontractors’ performance (Mbachu, 2008). The absence of claims or contractual disputes is a fair indicator of project success (Chan and Chan, 2004). Job satisfaction. Job satisfaction refers to the extent to which persons gain enjoyment or satisfaction from their efforts at work (Fogarty, 1994). It is a ‘soft’ measure, and has often been benchmarked with a company’s performance (Beatham et al. , 2004). Pinto and Pinto (1991) advocated that measures for project success should include project psychosocial outcomes, which refer to the satisfaction of interpersonal relations among project team members. Quality. Quality is defined as the degree to which general conditions promote meeting the project’s established requirements for materials and workmanship (Bubshait and Almohawis, 1994). The improvement of quality can reduce the resources and costs that must be devoted to reworking, which, when reduced, increases profitability (Ling et al. , 2009). The costs of rectifying defects and reworking have been estimated to be as high as 6. 2% and 12%, respectively, of the profit for a construction project (Thomas et al. 2002). Safety. Safety is defined as the degree to which general conditions promote the completion of a project without major accidents or injuries (Bubshait and Almohawis, 1994). Accidents during a project can be detrimental to the project in terms of time, costs and the reputation of the company (Chan and Chan, 2004). Environment. Environmental issues, such as waste management and public nuisance, have been regarded as negative environmental impacts on construction ( Shen et al. , 2000). Considerable attention has been directed towards finding out how to minimize construction waste and restrict environmental nuisance (Wong and Chan, 2000). Companies invest in the improvement of environmental protection because of cost factors (Tam et al. , 2001; Shen (3) Theoretical background Definition of performance criteria ‘Performance criteria’ are commonly shared mechanisms for monitoring and demonstrating project success (Krima et al. , 2007). Their use allows practitioners to understand their competitive position better and potentially to improve their performance (ElMashaleh et al. 2001). By looking at the deviations between the levels of importance of the performance criteria and performance outcomes, practitioners can review whether certain criteria underperform or overperform (Soetanto et al. , 2001). Ideally, performance outcomes of the performance criteria should be on a par with their normal performance, or, even better, their so-called ‘optimum per formance’, which are satisfactory to practitioners. Performance criteria of a construction project Atkinson (1999) stated that time, cost and quality make up the ‘iron triangle’ for project success. Loosemore et al. (2003) highlighted the importance of job satisfaction for the well-being of the construction industry. Fenn (2006) listed the typical performance criteria of commercial projects: time, cost, quality, project delays, delay claims, scheduling, monitoring and control. Lam and Wong (2009) argued that safety is a measure of project performance, as well as time, cost and quality. After reviewing the literature, nine performance criteria were selected: (1) Profit. Norris (1990) measured profit as the increment by which revenues exceed cost. Profit in terms of cost benefits has been identified as a key performance indicator (KPI) (Beatham et al. , 2004). Cost benefits can typically be achieved by savings and the early completion of projects (Soetanto et al. , 2001). Time. Time refers to the duration for completing a project (Chan and Chan, 2004). Time, cost and quality are the key factors a project (4) (5) (6) (7) (2) Performance criteria and Tam, 2002). For example, energy-efficient design allows both environmental friendliness and cost effectiveness across the project life cycle (Yao et al. , 2006). Generation of innovative ideas. Innovation is the actual novel use of a non-trivial change and improvement in a process, product or system (Slaughter, 1998). Innovation in construction leads to the improvement of working conditions, lowering construction costs, and decreasing construction time (Eaton et al. , 2006) so as to improve efficiency in the industry (Egbu, 2004). Effectiveness. Effectiveness is a characteristic of the overall performance of a project, in terms of whether it is being carried out within the budget, performed on schedule, and maintaining quality (Love et al. , 2004). Project effectiveness is dependent on conceptual level, skills and communicative abilities (Goodwin, 1993), which are important factors that affect project success (Krima et al. , 2007). Practitioners always intend to continually improve the effectiveness of the work process (Naoum, 2003). 379 importance of the performance criteria and their respective performance outcomes in a construction project in Hong Kong (as shown in Figure 1). In this study, three questions were addressed about the life of a construction project: Figure 1 A research model of importance of the performance criteria and their performance outcomes 8) (1) (2) (3) (9) What are the relative levels of importance of the performance criteria from the practitioners’ perspectives? What are the differences between the levels of importance of the performance criteria and their respective performance? What are the differences in the perception of performance from the practitioners’ perspectives? Research hypot heses The following hypotheses are formulated based on two variables: the importance of the performance criteria and their respective performance outcomes. Owing to the different dimensions of business-driven benefits and the degree of objective alignment (Thompson and Sanders, 1998), the levels of importance of the performance criteria may be different. H1: There are significant differences within the importance of the performance criteria. Research method Research model and research questions A research model is developed to examine, from different practitioners’ points of view, the levels of There are always levels of difference in the performance elements for construction (Soetanto et al. , 2001). The levels of importance of the erformance criteria may vary with respect to their performance outcomes. Figure 1 A research model of importance of the performance criteria and their performance outcomes 380 H2: There are significant differences between the importance of the performance criteria and their performance. Lai and Lam such as Mass Transit Railway Corporation Limited; and a private development project may include somethin g like a residential development project. The respondents include a staff of clients, architectural and engineering consultants who represent clients, and main contractors. The respondents are also classified into three functional roles (i. e. managerial, frontline supervisory and consultancy staff). This study only focuses on the performance of the key contract participants—neither suppliers nor subcontractors are included in this survey. Questionnaire development and administration A questionnaire is designed to gather information from people engaged in partnering projects in Hong Kong. A pre-test of the questionnaire was conducted in July 2006 with academics and construction practitioners in order to confirm the general validity and reliability. After the initial pre-test, a further pilot test was undertaken to check the suitability and appropriateness. The final questionnaire consists of two sections. Section 1 is about the background of the respondents and Section 2 is concerned with the views of the respondents on the levels of importance of the performance criteria of the project and on their performance outcomes. Respondents are asked to pick a rating using a five-point Likert scale, ranging from ‘1’ (the least important, or very unsatisfied) to ‘5’ (the most important, or very satisfied) in respect of the criteria and the outcomes. A total of 850 questionnaires were distributed in person to the respondents in August 2006. From the 209 questionnaires that were collected, 71. 8% were from the main contractors during the first three months. Thereafter, another 100 questionnaires were distributed only to accessible clients and consultants in October 2006. Statistical analyses are conducted using the Statistical Package for Social Sciences (SPSS) 12. 00 software package. Different stakeholders have different views and expectations of performance in a construction project (Newcombe, 2003). Different roles (i. e. clients, consultants, and main contractors) in a construction project may have different views on the same performance. H3: There are significant differences among incumbents in different roles in a construction project in the perception of performance among partners. There are differences between government and private projects in the respective business procurement and the relationship with contractors (Burnes and Coram, 1999). Different types of construction projects (i. e. overnment projects, public/private utility and private development) may require different types of performances. H4: There are significant differences in the perception of performance due to different types of construction projects. Partnering involves teamwork and collaborative activities for achieving goals and resolving problems (Pheng and Hong, 2005; Ingirige and Sexton, 2006). Staff in different functional roles (i. e. managerial, frontline supervisory and consultancy staff) may have different views on performance. H5: There are significant differences among staff in different functional roles in the partnering organizations in the perception of performance. Sampling method In Hong Kong, more than 500 construction companies are certificated with ISO 9001 (HKQAA, 2007). Because of the large number and different types of construction firms, the different sizes and types of construction works that are undertaken and the constraints of time and resources for the research, purposive sampling (Sekaran, 1996) is used to focus on the respondents who have participated in a partnering project. Contractors, consulting firms, government departments and private developers who are active participants in the construction market in Hong Kong are selected. Government departments and private developers are classified as clients of the construction projects. There are three types of project: a government project is a public project that is initiated from a government department such as the Housing Authority; a public/private utility project is usually an infrastructure project, for example, one initiated by a mass transportation services provider, Performance criteria of the construction project Research samples Over the six months prior to March 2007, 950 sets of questionnaires were distributed, from which a total of 324 were collected. The response rate is 34. 1%. The backgrounds of the respondents are shown in Table 1.

In this study, sample members are matched, and measurements across conditions are treated like repeated measures. Therefore, repeated measures ANOVA is used to find the rating among the performance criteria. Table A1 in the Appendix shows Mauchly’s test of sphericity. This is a test of compound symmetry or the homogeneity of covariance, an important assumption for this statistical test. If the test of sphericity is significant (i. e. , p-value < 0. 05), then the assumption H0 is met. Consequently, the univariate (more powerful) output (Tests of Within-Subject Effects) can be used. In this test, the p-value is less than 0. 5 and H1 is therefore accepted. This means that there are significant differences in the performance criteria. In order to elucidate the differences between them, Bonferroni’s test (see Table A2 in Appendix) is applied. The relati ve rating of the performance criteria is shown in Table 2 where time has the highest mean score, followed by profit, environment, quality, safety, effectiveness, no claims, job satisfaction, and the generation of innovative ideas. An individual paired-samples T-test is used to determine whether there are significant differences among the levels of importance of the performance criteria and their respective performances. The mean scores and standard deviations of the importance of the performance criteria and their performance outcomes are reported in Table 3. It shows that all of the factors have significant differences. The p-value is less than 0. 05. Therefore, H2 is accepted. Time has the highest positive paired mean difference, suggesting that the timely completion of a project, among the other performance criteria, seriously underperforms. One-way ANOVA is used to determine whether, among partners in different roles in a construction project (i. e. clients, consultants and main contractors), there are significant differences in the perception of performance. Table 4 indicates that there are significant differences in the perception of performance— with the exception of quality—among the three groups. The p-values for all of the factors (except for quality) are less than 0. 05. Therefore, H3 is accepted. The comparisons of the different groups are made using post hoc tests, after an overall significant difference has been obtained. The Tukey HSD table (Table 5) compares each group with every other group to determine the significance of the difference. Table 6 indicates that there is no significant difference (p-value > 0. 05) in the perception of performance due to the types of projects and between staff in different functional roles in the partnering organizations. Therefore, H4 and H5 are rejected. Discussion The levels of importance of the performance criteria The relative ratings for the highest levels of importance of the performance criteria are: (1) time; (2) profit; (3) environment; (4) quality; (5) safety; (6) effectiveness; (7) no claims or contractual disputes; (8) job satisfaction; and (9) generation of innovative ideas.

Krima et al. 2007) also noted that the importance of time performance is widely accepted. Most construction projects in Hong Kong are developed on a fast track schedule, completed in two to three years (Chan, 1999). The top concern in the construction industry in Hong Kong is always time. Profit generated from partnering normally derives from cost savings and incentives (Soetanto et al. , 2001). Incentives are normally introduced by offering a bonus to contractors achieving the KPIs set for the project (Swan and Khalfan, 2007). Moreover, profit sharing is very popular in construction projects. It is surprising that the improvement of environmental performance is the third most important performance criterion. Zhang and Shen (2000) observed that clients are often concerned with immediate or short-term results and care little about the potential benefits of improving environmental performance. This finding directly contradicts a previous study performed by Swan and Khalfan (2007), who found that time, cost and quality are the key elements for a successful project. Although the improvement of environmental performance is an important performance criterion, compared with the improvement of quality, this finding still needs to be clarified by further studies. The improvement of quality is always referred to in terms of less re-working or no abortive work (Thomas et al. 2002). Quality is also defined as conformity and client satisfaction (Soetanto et al. , 2001). It is always among the top priorities in construction. Safety has always been an issue in construction because of the routinely high accident rate involving deaths and property damage.

Policy makers and the general public always pay great heed to construction safety (Teo et al. , 2005). Effectiveness in construction has received negative commentary (CIRC, 2001). A rating solely on effectiveness itself is taken ordinarily to be insufficient and does not usually prevail. Claims in a project can involve extension of time (EOT), for example, because of inclement weather, or a variation order (VO), for example because of changes of design (Yeo and Ning, 2002). Contractors lose out from not being granted a claim. Although some previous studies suggest that job satisfaction is a measure of project success (Beatham et al. , 2004; Swan and Khalfan, 2007), an analysis of the data fails to find evidence suggesting job satisfaction is a priority in a construction project. Innovative ideas can contribute to cost savings and process expediting, and generating them should be encouraged through reimbursement or benefits sharing (Naoum, 2003). Nevertheless, innovative ideas about construction design and method are very rarely implemented in a construction project because of the relatively short timeline for completion. The differences of performance outcomes with respect to importance The relative ratings for the highest difference in performance with respect to the importance of the performance criteria are: (1) time; (2) safety; (3) quality; (4) environment; (5) profit; (6) job satisfaction; (7) effectiveness; (8) no claims or contractual disputes; and (9) generation of innovative ideas. All of the performance criteria clearly underperform. Timely completion of the project displays the highest difference. To a project owner, delay means loss of revenue due to slackened production and rentable space. To a consultant, delay means either the failure of progress monitoring of contractors or faulty design, or both. To a contractor, delay means penalties and higher overhead costs. It is thus very worthwhile to investigate the cause of delay, the parties who are responsible, and the preventive measures for avoiding it (Assaf and Al-Hejji, 2006). Owing to stringent legal and contractual requirements in Hong Kong, there are ever-increasing demands, expectations and emphasis on safety, quality and environmental protection. Naoum (2003) has argued that there should be a comprehensive incentive scheme to simulate the overall site performance in these categories. Profit is a basic goal for running a business, but in a project, it is always governed by the traditional re-measured contract at a fixed price. 385 Participants in a construction project can only benefit from cost savings or bonuses awarded by accelerating the process for early completion (Tam, 2002). Job satisfaction is among the performance criteria displaying a low performance outcome. Not only are staff members not happy about job satisfaction, but this variable is also in fact rated as the second least important performance criterion (see Table 2). The effectiveness of a construction process needs both good planning and coordination. Given the inherently fragmented nature of construction, work is always accomplished in sequential and unique stages handled by different contractors. Since the design and building processes are normally divided between consultants and contractors (Naoum, 2003), the original designers would thus not help the performance outcome or effectiveness of the construction process once it is underway. No claims or contractual disputes are part of the second-lowest performance outcome. Claims or contractual disputes in a project are very often raised among clients and contractors (Yeo and Ning, 2002). The generation of innovative ideas for construction design and method received the lowest rating concerning performance outcome. In fact, adopting new ideas in construction is always inhibited by the fact that there are always prior specifications governing construction activities (Naoum, 2003). Winch (2003) noted that construction is commonly characterized as a ‘backward industry’, that is, one that fails to innovate in comparison to other sectors. The strong categorical division of responsibility for design and building worsens this situation. The performance perceived by practitioners in different roles in a construction project Profit There are significant differences between clients and the main contractors in the perception of the performance of profit. Clients are more satisfied than are the main contractors (see Table 5). Clients typically set out the budget for a project at the beginning of project planning, whereas contractors concentrate on cost savings (e. g. reducing the opportunity for claims). Time There are significant differences between clients and main contractors in the perception of performance for the timely completion of projects. Clients are more satisfied than are main contractors (see Table 5). They are normally proactive and generally push for timely completion. Main contractors prefer a contract designed with a reasonable duration for the construction 386 time and fair treatment of claims for EOT (Assaf and Al-Hejji, 2006). Any completion delay for a project will be the subject of a penalty for liquidated damages to a contractor (PAH, 2008). In general, clients would consider an incentive bonus for the contractor who completes the project on time or ahead of schedule (Naoum, 2003). Contractors prefer these bonuses as an incentive for finishing on time or early. No claims or contractual disputes There are significant differences between clients, consultants and main contractors in the perception of the performance of no claims or contractual disputes. Clients and consultants are more satisfied than are main contractors (see Table 5). When initiating a contract, clients normally would have a contingency plan to provide additional money for any claim, for a delay in the project or for a change of design. In general, clients and main contractors take a different stand on claims. Clients suffer from claims, while the main contractors benefit. Traditionally, clients are perceived as distrustful and suspicious, while the main contractors are perceived as opportunistic and greedy (Kadefors, 2004). Consultants tend to have a passive attitude to claims, and do not like to see any claims or contractual disputes, as they might be taken to reveal their own faulty design or their failure to perform their duty of supervising the main contractors’ performance. Job satisfaction There are significant differences between clients, consultants and main contractors in the perception of the performance of the job satisfaction of staff. Staff members, as consultants and main contractors, are less satisfied than are clients (see Table 5). Staff from clients may participate in the partnering projects more than do the staff from consultants and main contractors. Since the levels of participation for different parties are different, they show differences in regard to this issue. Quality There is no significant difference between clients, consultants and main contractors in the perception of the performance of quality. This seems to illustrate that all partners in the construction project hold consistent views on the performance of quality. Safety There are significant differences between clients, consultants and main contractors in the perception of the performance of safety. Consultants are less satisfied than are clients and main contractors (see Table 5). Clients simply do not like to see any accidents. The Environment Lai and Lam responsibility for onsite safety is therefore ascribed to the consultants and the contractors (Teo et al. , 2005). Consultants take a passive role in safety during the operations (Teo et al. , 2005); they like to have sufficient planning and budgets for the design of safety at the beginning of a project (Wong and Chan, 2000). The main contractors bear most of the legal liability for safety performance (Chan and Chan, 2004); they commit to ensuring safety under a contractual requirement. There are significant differences between clients and consultants in the perception of the accomplishment of environmental performance. Consultants are generally less satisfied than are clients (see Table 5), who showed less concern in improving environmental performance. This empirical finding agrees with Yao et al. ’s (2006) basic argument. The design of environmentally friendly projects involves reduced use of natural resources, recycling of construction waste, and the avoidance of being a nuisance in the neighbourhood (Tam et al. , 2004). The green construction concept demands that, at the inception of a project, approval is sought from the client. Although consultants are reactive on this specific issue, they can propose some guidelines for administering a contract’s environmental requirements (e. g. contractors should prepare a comprehensive onsite waste management plan). Clients should consider covering all of the costs incurred in those contract specifications satisfying these environmental requirements. On the other hand, contractors do not totally disagree with this concept and are usually willing to follow some guidelines, such as avoiding environmental hazards and following safety procedures. Indeed, clients should regularly take the initiative to monitor and closely inspect contractors’ performance of environmental management. Generation of innovative ideas There are significant differences between clients, consultants and main contractors in how they perceive the accomplishment of innovative ideas about the construction design and method. Consultants are less satisfied than are clients and main contractors (see Table 5). In general, consultants play a significant role in generating new ideas about the construction method and the design (Bresnen and Marshall, 2000). The main contractors usually do not put too much effort into promoting innovative ideas unless it is a designand-build project. However, consultants are reluctant to accept a contractor’s design proposal (Bresnen and Marshall, 2000). In fact, the best innovative ideas for construction design and method should be developed by consultants during the planning phase. However, Performance criteria given the zero-growth budgets and tight schedules for construction projects, consultants seldom take the initiative to generate innovative ideas even though they should. Effectiveness There are significant differences between clients, consultants and main contractors in the perception of the relative effectiveness of a construction process. Clients are more satisfied than are consultants and main contractors (see Table 5). Consultants, as designers, play an important role by providing good, reliable and complete designs that are buildable. Main contractors play an active role in the construction process (Arobos, 2002; Errasti et al. , 2007), dealing with most of the problems raised during the construction stage along with the consultants. Most of the problems generated at the site level and the effective solutions do not involve the clients. The performance of important aspects of different types of construction project There is no significant difference between the three groups in the perception of the performance of government project, public/private utility and private development. This means that there appears to be no relationship between performance outcomes and the types of projects. The performance perceived among staff in different functional roles in partnering organizations There is no significant difference between the three staff groups: managerial, frontline supervisory and consultancy, in terms of the perception of performance. This means that there is no relationship between the performance outcomes and the staff in different functional roles in the partnering organizations. 387 and management of, a project, exacerbate the adverse effects of the fragmented nature of construction. There are many methods for trying and overcoming the barriers to optimum performance. For example, the ideas of the public–private partnership (PPP) and the private finance initiative (PFI) projects, which create a favourable partnering atmosphere between clients and the main contractors (Li et al. , 2005), could help diminish the abovementioned problems. PPP and PFI embrace all of the elements in a successful construction project of design, build and finance, which means a longer project timeframe and a contract sum sufficiently large so as to sustain the partnering atmosphere. Other methods, such as awarding contracts based on quality bids, as well as prices and partnering frameworks, are also recommended. Limitations Owing to the large numbers of the sample size and frame and the limited time and resources available, the selection of questionnaire respondents was based on the rationale of purposive sampling, aiming to select some specific categories in the populations. This may cause bias and error. The collected data were mainly from the main contractors and clients (84% of the total respondents) and may have led to biases that render the result inaccurate. A holistic supply chain must be expansive, embracing the vertical networks of subcontractors and suppliers for better partnering. There were also geographical limitations in this study. The survey was only carried out in Hong Kong. It would be beneficial to have the opportunity to test the theory elsewhere. Further research opportunities The results indicate that timely completion of a project is both the most important performance criterion and the highest in terms of the difference in the outcome of the performance with respect to importance. Future studies should seek to elaborate on this factor, exploring how to improve the time actor in a construction project. A new research tradition can be built on a more detailed model that specifies not only the relationships between the independent and dependent variables, but also the relationships between the independent variables. This means an investigation of the correlation between the factors of two variables as well as within the factors. In such a study, there should be a deeper focus on the correlation among the performance criteria. Regarding the significant difference from the perspectives of clients, consultants and main contractors about the performance outcomes, further additional research is necessary in order to elaborate on the Implications, limitations and further research Implications The present results reveal that, in order to achieve optimum performance, a company should improve its operations by managing the presence of the nine performance criteria. The differences in the perceptions of performance among the key contract participants in a construction project reveal the congeniality problems in the construction industry. The rule of the contract game, or that the lowest price wins, still very much dominates the final decision on the selection of contractors. The division of roles between designing and building, and the distinct roles of consultants for 388 more subtle rationale of these differences. A more qualitative data collection method through intensive interviews with participants would provide richer and more in-depth data. Lai and Lam more fairly when claims are made. Practitioners have less concern about the generation of innovative ideas for a construction method and design that make least deviations from performance. Finally, there is no difference in the perception of performance due to the types of projects, or between those staff in different functional roles in the partnering organizations. This study in Hong Kong examined, from the points of view of practitioners, the levels of importance of the performance criteria and their respective performance in construction projects. The research reviews the status quo of partnering and the congeniality problems in the industry, and it is intended to stimulate interest in Hong Kong for further exploration of solutions for improving the overall performance of the construction industry. Conclusions Here, we rate the performance criteria in a construction project in Hong Kong. The order of importance of the performance criteria is: (1) time; (2) profit; (3) environment; (4) quality; (5) safety; (6) effectiveness; (7) no claims or contractual disputes; (8) job satisfaction; and (9) generation of innovative ideas. There are differences among the levels of importance of the performance criteria with respect to performance. The positive differences between the levels of importance of the performance criteria and their performance outcomes indicate a common pattern: all of the performance criteria underperform. The results of the greatest differences are, in order, (1) time; (2) safety; (3) quality; (4) environment; (5) profit; (6) job satisfaction; (7) effectiveness; (8) no claims or contractual disputes; and (9) generation of innovative ideas. Timely completion of the project is the most important performance criterion, but it displays the highest deviation of its performance when compared with its importance. This implies that time management is the most critical factor for the performance of a construction project. In Hong Kong, events pertaining to quality, safety and environmental issues during construction always generate a great deal of publicity. In fact, there are quite regular incidents regarding substandard work, serious accidents on construction sites, and complaints regarding pollution and nuisance generated from construction activities. The performance of these three performance criteria can be improved by providing a greater budget during the planning of the project, or by allowing a larger budget for design and incentives to achieve good performance. Most clients are satisfied with the performance of profit, although the main contractors are less happy, reflecting the fact that, with the prevailing lowest-pricewins and the procurement practice in construction, the main contractor still stands to lose. In general, most respondents are not satisfied with job satisfaction. The job satisfaction of staff should be enhanced through personal development, job security and encouragement from colleagues and superiors. Most clients are satisfied with the performance of the effectiveness of the construction process. Consultants should strive to improve the effectiveness of the construction process early in the design stage of a project and should suggest adopting more design-and-build types of contracts. Clients are satisfied with fewer claims and contractual disputes. However, contractors would like to be treated References ACITS (1997) Repeated measures ANOVA using SPSS MANOVA.
