An Excerpt from Classic Monologue Oedipus the King
An Excerpt from Classic Monologue Oedipus the King This Greek tragedy by Sophocles is based on the ancient legend of a fallen hero.à The story has several interchangeable names includingà Oedipusà Tyrannus, Oedipus Rex, or the classic,à Oedipus the King.à First performed around 429 BC, the plot unfolds as a murder mystery and political thriller that refuses to reveal the truth until the end of the play. The Mythic Tragedy Although it was crafted thousands of years ago, the story of Oedipus Rex still shocks and fascinates readers and audience members alike. In the story, Oedipus rules over the kingdom of Thebes, yet all is not well. Throughout the land, there is famine and plague, and the gods are angry. Oedipus vows to find out the source of the curse. Unfortunately, it turns out that he is the abomination. Oedipus is the son of King Laius and Queen Jocasta and unknowingly marries his mother, who he ends up having four children with. In the end, it turns out that Oedipus has also murdered his father. All of this, of course, was unbeknownst to him. When Oedipus discovers the truth of his actions, he is wrought with horror and self-loathing. In this monologue, he has blinded himself after witnessing his wifeââ¬â¢s suicide. He now devotes himself to his own punishment and plans to walk the earth as an outcast until the end of his days. What Readers Can Take Away from Oedipus the King The significance of the story surrounds the character development around Oedipus as a tragic hero. The suffering he endures as he goes on his journey in search for the truth is different from his counterparts who have killed themselves, like Antigone and Othello.à The story can also be seen as a narrative around family ideals about aà son who is competing with his father for his mothers attention. The ideals set by Greek society are challenged by the Oedipus character. For example, his personality characteristics such asà stubbornness and anger are not that of the idealized Greek man.à Of course, the theme around fate is central as the gods have willed it toward Oedipus. It is only until he is king of the land that he learns about his dark past. Although he was a model king and citizen, his complexity allows him to be labeled as a tragic hero. An Excerpt of the Classic Monologue from Oedipus the King The following excerpt from Oedipus is reprinted from Greek Dramas. I care not for thy counsel or thy praise;For with what eyes could I have eer beheldMy honoured father in the shades below,Or my unhappy mother, both destroyedBy me? This punishment is worse than death,And so it should be. Sweet had been the sightOf my dear childrenthem I could have wishedTo gaze upon; but I must never seeOr them, or this fair city, or the palaceWhere I was born. Deprived of every blissBy my own lips, which doomed to banishmentThe murderer of Laius, and expelledThe impious wretch, by gods and men accursed:Could I behold them after this? Oh no!Would I could now with equal ease removeMy hearing too, be deaf as well as blind,And from another entrance shut out woe!To want our senses, in the hour of ill,Is comfort to the wretched. O Cithaeron!Why didst thou eer receive me, or received,Why not destroy, that men might never knowWho gave me birth? O Polybus! O Corinth!And thou, long time believed my fathers palace,Oh! what a foul disgrace to human natureDidst thou receive ben eath a princes form!Impious myself, and from an impious race.Where is my splendor now? O Daulian path!The shady forest, and the narrow passWhere three ways meet, who drank a fathers bloodShed by these hands, do you not still rememberThe horrid deed, and what, when here I came,Followed more dreadful? Fatal nuptials, youProduced me, you returned me to the wombThat bare me; thence relations horribleOf fathers, sons, and brothers came; of wives,Sisters, and mothers, sad alliance! allThat man holds impious and detestable.But what in act is vile the modest tongueShould never name. Bury me, hide me, friends,From every eye; destroy me, cast me forthTo the wide oceanlet me perish there:Do anything to shake off hated life.Seize me; approach, my friendsyou need not fear,Polluted though I am, to touch me; noneShall suffer for my crimes but I alone.

The literature about the determinants of dividend policy discussed in the previous section is collected from various empirical researches based on different conditions. Introduction The literature about the determinants of dividend policy discussed in the previous section is collected from various empirical researches based on different conditions. IntroductionConclusionRelated Introduction The literature about the determinants of dividend policy discussed in the previous section is collected from various empirical researches based on different conditions. Some of the results are gleaned from surveys by directly asking the managersââ¬Ë view towards dividend policy; some are gleaned from statistical analysis by observing the companiesââ¬Ë financial data; others are just a theoretically deductive process conducted by academicians. Therefore, it is necessary to find out that whether those determinants gained from the empirical literature can work properly in Financial Service industry in UK market. Thus, 9 hypotheses with respect to each of the determinants have been raised. H1: All else equal, dividend policy relies upon firmââ¬â¢s earnings power. This paper expects that more profitable firms should pay more dividends in UK stock market. Firms with high profitability have the capacity to provide large cash flow. Therefore, there is no need to worry whether the fi rms have enough cash flow to payout dividends even if a lot of cash flow is used to finance new investments. Thus, it can be hypothesized that profitability has a positive relationship with dividend payouts. As a proxy, the level of firmsââ¬Ë profitability can be measured by the return on assets (ROA). H2: All else equal, dividends signals future earnings growth. This paper expects that low dividend payments will predict a high earning growth in UK market. Dividends act as a signaling mechanism under the imperfect market situation, where information asymmetry exists between managers and investors. Managers often process and trade on information about firmââ¬Ës future earning fluctuation through dividend payments. Therefore, any change in dividend policy will be interpreted as a change in managementââ¬Ës expectation of future earnings. Under the circumstance oflimited cash flow, more investment opportunities actually mean high future earnings growth, but in the same time, will reduce the free internal cash flow available for dividend payments. Therefore, it can be hypothesized a negative relationship between dividend payouts and future earnings growth. Annual rate of growth of earnings per share (GROWTH) is commonly used as a proxy for firmsââ¬Ë earning growth. H3: All else equal, dividend and debt are direct substitutes. This paper expects that the level of risk will be negatively related to dividend payments in UK market. Fir ms with high debt ratios are more likely to pay a lower level of dividends, because they have already pre-committed their cash flows to make debt payments and to avoid borrowing more capital. Thus, high leveraged firms do not have sufficient cash flow to afford high dividend payment, and reflect a negative relationship. Firmsââ¬Ë leverage ratio (LEV) is used to represent risk in statistical analysis. H4: All else equal, past dividend have influence on current dividend policy. This paper expects a positive relationship between past dividend and dividend payouts in UK market. The signaling function of dividend payments suggests that any change in dividend policy reflects changes in the managersââ¬Ë prediction of firmsââ¬Ë prospects. In addition, both the market and the firms prefer certain degree of continuity in dividend payments. Therefore, past dividend payments is essential in the decision making of future dividends. Lintnerââ¬Ës partial adjustment model and target pay out ratio present a positive relationship between the two variables. As a proxy for continuity of dividends, past dividend (PD) can be used and a positive relationship can be expected from the result. H5: All else equal, liquidity/ cash flow is the fundamental element in dividend paying. This paper expect dividend payments positively correlated with firmsââ¬â¢ cash flow in UKmarket. Sometimes, the concepts of cash flow and profit is two different things. The former is the free cash flow in the companies available for companies operating and investing activities, the later means the current earnings of the firm. The empirical experience tell us that even companies with negative earnings pay dividend to shareholders to maintain a stable dividend payments, and transfer the information of temporary losses to the public. In that case, only the free cash flow of the companies matters when dividends are distributed to shareholders. A poor liquidity position means less generous dividends due to shortage of cash. Therefore, it can be hypothesized that firms with high cash flows have the tendency to allocate more to paying dividends. The variable used is the cash flow per share (CFPS) an d it should have a positive impact on dividend payout ratios. H6: All else equal, larger firms distribute larger dividends. This paper expects that dividend payments will be positively associated with size of the firm in UK market. In the imperfect capital market, where the investors and firms cannot borrow at the same cost, larger firms should have easier access to external funds and can borrow at a cheaper rate than small firms can. In addition, being more competitive than smaller firms are, larger firms should have more investment opportunities, and therefore high future earnings growth can be expected. In that case, managers of large firms are more likely to distribute high dividend payments, and convey their positive expectations of the firmsââ¬Ë prospect. As a common surrogate for size is logarithm of the firmsââ¬Ë total market value (MV) and it is expected to be positively correlated to dividend payouts. H7: All else equal, dividend payments operates as an information s ignal. This paper expects that firms with greater investment opportunities will pay lesser dividend in UK market. Asymmetry information provides a new insight into the explanation of dividend puzzle. The unequal information barrier of the insiders and outsiders inevitably highlight the importance of dividend payments acting as a medium to convey information for the two parties. Meanwhile, because of the general tendency for stable dividend payouts, any change in dividend policy is recognized as an information exposure of firmsââ¬Ë prospects. Therefore, rather than distributing more to shareholders, managers are likely to retain more to satisfy the financial needs required by future investment opportunities. Thus, a common proxy for investment opportunities is the market-to-book ratio (MBV) and it is expected to be negatively associated with dividend payouts. H8: Financial crisis has jeopardized the economy on a worldwide basis. This paper expects that financial distress will infl uence dividend policy in service industry in UK market. Happened in the middle of 2007, financial crisis lasted for almost two years, and has brought great damage to global economy. The major victim of financial crisis is global banks and financial institutions. Other industries will be more or less affected by the influence of financial pressure. In the three years of financial crisis, almost all the industries are confronting the increasing requirements of free cash flow. However, during this period, both banks and financial institutions are extremely lack of funds, and therefore, cannot satisfy the financial requirements of the market. As a response to this serious situation, tougher capital constrains resulted in high costs for borrowing from external sources. Therefore, for companies, financial crisis raised the pre-determined cost of debt, and in turn reduce the amount of cash flow for dividend payments. H9: Different industries have different regulations and laws. This paper expects that different industrial classification will result in different dividend policies in UK market. It is generally accepted that firms adjust their dividend policies to suit the particular circumstances facing the industry in which they operate. Like for instance, firms in high growth industries will enjoy many financing discounts from the regulations, therefore, facing more advantages in investing and financing activities. Thus, it is necessary for them to modify their dividend-based strategies in an attempt to maintain more retained earnings for more new investment opportunities. Nevertheless, firms in mature and saturated industries ought to maintain stable dividend payouts rather than to reserve more retained earnings when investment opportunities are limited in their industrial sector. The expectations of this paper and the previous researchersââ¬â¢ attitudes towards the relationship between divid end policy and its determinants can be summarized in the table 1. Conclusion Proxies Variables Expected Literature indicated relationship PR dividend payout policy ROA profitability Positive Positive GROWTH earnings growth Negative Positive or Negative LEV level of risk Negative Negative PD past dividens Positive Positive CFPS liquidity Positive Positive MV firms size Positive Positive MTBV investment opportunities Negative Negative or no relationship.

Comparison of Ingre's 'Grande Odalisque' and Titan's 'Venus of Urbino' Essay
Comparison of Ingre's 'Grande Odalisque' and Titan's 'Venus of Urbino' - Essay Example The depiction of the female nudity in history of art exists in plenty; as does the archetype from which these nudes got styled. Titian and Ingres were deliberated as some of the most significant artists of their time; accredited with being broad - minded and conservative (Gardner 290). Noting the painters and paintings, they stand as genius on their own considering their individual contributions which are monumental to the corresponding movements. Through identifying these works through their separate form content and context, the two works will be compared and contrasted. It remains easy to describe Ingres as a consistent supporter of the Neo - Classical stylishness from his period in David's studio to the mid19th century. Ingres returned to Neo - Classics after having overruled the lessons of David, his teacher, and after having set the foundation for the emotional Romanticism expressiveness, the new style of young Delacroix and Gericault that Ingres would ultimately defend. Ingres' early Romantic penchants can be seen most legendarily in his work ââ¬Å"La Grande Odalisqueâ⬠painted in 1814. On Ingresââ¬â¢, Grande Odalisque, a languid nude is outlaid in a sumptuous interior. On its first glance this nude appears to follow in the convention of the Venetian masters, for instance, Venus of Urbino (1538) by Titian. However, upon closer scrutiny, it seems that this is not a classical setting. Instead, Ingres has generated a distant eroticism emphasized by its exotic context. This work is full of sensuality, idealization and mystery. The background seems quite undefined with a purported black portion that makes it more attractive. The different shades of bluish clothing and decorations make the picture more striking to the viewer. The womanââ¬â¢s gaze, like Titanââ¬â¢s Venus, is directed straight towards the spectator and the fan made of peacock feathers in her hand looks as if it has just been used. Odalisque position and size gives a deeper meaning although, it is much more than a naked lady staring at the viewer. She reflects her life as a concubine, on her duties . She is believed to have been part of the sultanââ¬â¢s harem, she was there to satiate the lascivious pleasures of the sultan, despite what she may want or feel. She reflects a woman with deep thoughts, complex feelings and emotions (Lewis 328). In the cognizance of a 19th century French male observer, the sort of individual for whom this picture was made from, the odalisque would have made up not only a harem slave, being itself a fallacy, but a set of desires and fears connected to the long aggression history between Islamic Asia and Christian Europe. Certainly, Ingres' porcelain sexuality is acceptable even to a progressively prudish French culture due to its subject's distance. While the Renaissance painter Titan veiled his eroticism in myths, Ingres covered his piece of desire in a murky exoticism. Some art historians suggest that colonial politics played a role too on the work. France was expanding its African and Eastern possessions, often brutally at this time (Gardner 4 41). The myth of the barbarian served the French who would then claim a moral authoritative. Incidentally, on clear look, anyone can notice something "wrong" with the figure's anatomy. Titian is deliberated to have been an outstanding Venetian painter of the 16th - century, and the former of the Venetian colorist and painterly tradition. He remains one of the significant figures in the Western art history. Tiziano Vercelli got born in the northern Venice, in 1477. He got trained by both Giorgione and Bellini, and after

Internal Analysis on Mr Empanada Restaurant Research Paper
Internal Analysis on Mr Empanada Restaurant - Research Paper Example Its vision as a restaurant is to exceed all the expectations of its clients while also giving back to the company that has supported it. According to its vision, Mr. Empanada will soon make its special delicacies as well known by the American public as hamburgers and pizza (Mr. Empanada). Product/services Identification The main food products created by the Mr. Empanada restaurant are empanadas. Empanadas are actually fried or baked stuffed pastries. They are a Spanish delicacy that has been adopted in many nations due to their delicious taste. It is believed that the Empanada recipe was originally developed in the Middle East but was carried to Spanish Europe by tourists and travelers. Today, Empanadas can be found in almost all nations of the world; with each culture using its preferred stuffing or altering the recipe to suit local tastes. Customer Identification One of the reasons why Mr. Empanada is so successful is because it puts such a high premium on providing the very best f or its customers (Yang and Fu 117). For example, Mr. Empanada often tries to implement the advice that is given in customer reviews when seeking to improve its services. It views customer feedback as a way through which to gauge the popularity of its products and service with its best customers. VALUE CHAIN OF MR. EMPANADAââ¬â¢S RESTAURANT Inbound Logistics Mr. ... Most of its raw vegetables are procured from fixed suppliers. Mr. Empanada also favors the practice of backward integration to ensure that all unnecessary costs are reduced, and also to make sure that it only uses the best quality of products to produce its foodstuffs. It is necessary for the outfit at Armenia Avenue to have distribution networks that can carry food stuffs ready for preparation to each of Mr. Empanadaââ¬â¢s six restaurants based in Florida (Mr. Empanada). The restaurant has enormous warehouses from which food supplies are shipped by truck to the different restaurants around Florida. Every franchise of Mr. Empanada is part of a centralized chain management process; with only the Russian branch which handles its own distribution and warehousing operations. In the past, operations at the Mr. Empanada restaurant were tracked. The restaurants managers would keep an inventory on food objects and utensils, among other things. Everything that was needed for the restaurant to operate on various shifts would be ordered for on the day before from the distribution center. However, changes were made which made it easier to follow the business operations. With the introduction of automation, the various requirements of different franchises are noted and recorded by a computer. The normal routine today is that the distribution center at Armenia Avenue ships the needed items to various franchises by following a regular schedule. This has allowed the restaurant to be able to serve more customers faster and more efficiently. It has also allowed the business to benefit from cost cutting through discounts that it gets from regular supplies when it regularly purchases whole sale products (Partridge). Outbound

Socio-Economic Profile of a Switzerland Essay Example | Topics and Well Written Essays - 2500 words
Socio-Economic Profile of a Switzerland - Essay Example In the paper, Switzerlandââ¬â¢s status regarding Market Economy and Productivity, Purchasing Power Parity and Human Development Index are discussed. Religion is an important social variable that often determines the associated risk factors with a certain form of business. The religious stubbornness of the people of a country might put many constraining factors on the business environment of that country. By December 2010 the population of Switzerland was 7.9 million (. According to a publicly funded study the foundation of religious belief in Switzerland is eroding at a fast pace. 32 percent of Swiss populations are Protestant and 31 percent of them are Catholics; 12 percent are of non-Christian religion and 25 percent does not have any religious beliefs. Forty years ago the scenario was lot different when only one percent of the Swiss population was bereft of any religious belief. In the year 2000, the same figure stood at 11 percent. Language is the most important form of person al communication. Since in business communicating with people is most necessary, hence having a clear knowledge of the official languages of a country before setting foot upon its soil is most important from the business point of view. The four official languages of Switzerland are German, French, Italian, and Rumantsch. The meaning of body language and etiquette along with corporate culture differs from country to country. Knowing the meaning of the same might make a difference regarding success or failure of a business decision. The Swiss value ââ¬Å"cleanliness, honesty, hard work, and material possessionsâ⬠. The Switzerland motto is ââ¬Å"Unity, yes; Uniformity, no.â⬠The Swiss people are ââ¬Å"proud of their environment and have a long tradition of freedom. They value sobriety, thrift, tolerance, punctuality and a sense of responsibility.ââ¬

Introduction to Synchronization
Introduction to Synchronization Synchronization is a mechanism which helps to use shared memory resources in an operating system. In the current world, most of the computers are multi-tasking computers. So these computers can do more than one process at the same time. And the networking technology is has become one of the most modern and developed technologies in the current worlds. So both these computer and network technologies work together in order to achieve common goals. While working together these technologies have to share resources such as memory at the same time. While sharing memory, there can be many problems. To avoid these problems synchronization mechanisms were implemented. Concurrency As it is mentioned above, operating systems share memory in order to achieve common goals. The data can be shared among two processes in one operating system or two operating systems over a network. However there are sometimes that the shared data can be accessed by only one process at a time. As a real life example, shared bathroom can be taken. A shared bathroom can be used by many people but it can be used by only one person at the time. If someone is using the bathroom, others have to wait until that person to come out. Then the one of the waited people can use the bathroom. Another real life example for this is shared streets or junctions. In shared streets, people can use only one direction at one time. If the shared street is used by any direction, people from other direction have to wait till others to stop using the shared street. Otherwise there can be clashes and a lot of problems. Like these, when the operating systems use shared memory, sometimes only one process can acc ess the data at one time. So this is called concurrency. There must be some mechanisms to avoid this concurrency. In the above given two real life examples, the shared bathroom can use a lock in its door to make sure that only one person is using the bathroom at one time. In the shared streets, traffic lights can be used to make sure that only one direction is using the street and avoid the clashes. Like this, locking and synchronizations are the mechanisms that can be used to avoid concurrency in operating systems. Properties of systems with concurrency There are some properties of the systems with concurrency. Those properties are, multiple actors, shared resources and rules for accessing the resources. In the above given two real life examples, the multiple actors are people and vehicles while the shared resources become bathroom and street. The rules for accessing these shared resources are one person at one time for the bathroom and one direction for one time for the shared streets. When talking about these three properties in relating to the operating systems, it can be explained like this. Here, the multiple actors are processes within the operating system or threads in processes. Shared memory, global variables and shared devices can be taken as the examples for the shared resources property while locking and semaphores techniques become the rules for accessing the shared resources in operating systems. These are the three properties of the systems with concurrency and it helps to understand what the concurrency is. Situations with no risk of concurrency In the current computer technology, there are some situations that there is no risk of concurrency but the shared resources are accessed by more than one processes or threads at the same time. Those situations are as follows, No shared memory or communication :- Here, the processes or threads do not have shared memory or communication. So those processes or threads work only with its private memory. Shared memory with read-only access :- Here, the shared memory can be accessed by one or more processes or threads at the same time. But in this situation, the shared memory is only available for processes or threads to read-only. So the shared memory cannot be modified in this situation. Copy-on-Write (COW) :- Here, the shared memory is accessed by one or more processes or threads at the same time and each process or thread has a separate copy of the shared memory. So each process is accessing its own copy of the shared memory and there is no risk of concurrency. Situation with risk of concurrency As well as the situations with no risk of concurrency, there are some situations with risk of concurrency in the current operating systems. Those situations can be explained as follows, Using of shared memory without any synchronization :- Here, if the shared memory is accessed by more than one processes or threads at the same time without and synchronization (without having any separate copy for each process or threads), there is a risk of concurrency. Any modification to the shared memory :- If the shared memory is accessed by more than one processes or threads, and at least one of the processes or threads makes any changes to the shared memory, then there is a risk of concurrency. These are the situations with risk of concurrency. If one of these happens, then there is a risk of concurrency in the system. If a concurrency is happened, then there may be a lot of problems in the system. And the risk of happening the concurrency is known as race condition. Race condition Under this topic, the race conditions is discussed by using an example. Here, an example of a bank account is taken to discuss the race condition. In this example, there are two peoples and a bank account. Execution of the code of this example as follows, account.balance = à £200; int withdraw (account, amount = à £50){ balance = account.balance; balance -= amount; int deposit (account, amount=à £100){ balance = account.balance; balance += amount; account.balance = balance; return balance; } account.balance = balance; return balance; } For this example, the two persons are named as person1 and person2. The code executed by the person1 is coloured with blue colour while the code executed by the person2 is coloured with red colour. This is a sketch of the programme but not coded with any programming language. In the very first line, the balance of the account is set to à £200. The rest of the code is explained as follows, Line 1 :- person1 starts executing the code and calls the withdraw() by giving the account and à £50 of amount as the parameters. Line 2 :- person1 reads the balance from the account class and assigns the value of balance variable in account class to his balance variable in his withdraw(). Line 3 :- person1 modifies the value of the balance variable in his withdraw() by subtracting the value of amount. So the value of the balance variable in his withdraw() becomes à £150. Line 4 :- In this line, the person2 starts executing the code by calling his deposit() by parsing account and à £100 of amount as the parameters. Line 5 :- Here, person2 reads the value of the balance variable in account class and assigns it to the balance variable in his deposit(). Here, still the value of balance variable in account class is à £200 as the person1 has not updated the balance in account class. Line 6 :- Person2 modifies the value of the balance variable by adding the value of amount variable to it. So the value of balance variable in deposit() becomes à £300. Line 7 :- person1 updates the value of the balance variable in the account class as à £150. Line 8 :- person 1 returns the value of the balance variable in withdraw() Line 9 :- person2 updates the value of the balance variable in the account class as à £300 Line 10 :- person2 returns the value of the balance variable in his deposit() After executing this code 2 peoples complete their transactions by leaving the final value of the balance variable in account class as à £300 while the real value of the balance variable in account class has to be à £250. So there is clear error in the final output of the process and this is called as the race condition. Manage concurrency Manage Synchronization means, use synchronization mechanism programs to write rues for control concurrency situations. One of these rules are as follows: Atomicity Atomicity allows one threat to access data to manipulate at a single situation. In another way, will allows no other threats to change data while one is running. This will either will lock the threat is in progress of manipulating the record or let other records to be waiting while one record access record. The other rule is conditional synchronization In this explain threats will be in a particular order to access the record. When threats arrives to access record rule will check the order and add to the queue and let wait until the turn of the threat to access the records. All above access methods will be easy to implement when can identify which is the critical part of the process should allow to access at a time. i.e. When Person A accessing account balance person B not allows to access balance at the same time. If extract further as bellow. 1.int withdraw (account, amount) { 2.int balance = account.balance; 3.balance -= amount; 4.account.balance = balance; 5.return balance; 6.} Line 1: will initialize threat and pass external parameter values into the threat withdraw as account and amount in this situation. Line 2: will declare balance variable locally to retrieve stored account balance from the database for threat to process and pass account balance in the account table account.balance. Line 3: will manipulate balance variable value (in this situation, we will deduct since it is withdrawal) from the amount has been pass form external parameter. -= notation for the deduction. Line 4: will update database with new balance value after withdrawal amount deducted from original balance. balance which is a local variable holding the new balance transfer to the account.balance and update record with new balance value. Line 5: will return new balance value to the screen if necessary Line 6: will terminate the process of withdraw by } There will be no concurrent when two threat access lines 1, 5 and 6. But if any threat try to access lines 2, 3 and 4 will be given incorrect information for one of the threats. Therefore from line 2 to 4 is very critical to let access only for one threat at any given time of the process as explain bellow. int withdraw (account, amount) { int balance = account.balance; balance -= amount;Critical Section account.balance = balance; return balance; } This identified sections will call as a critical section in another word, no other threats will allows to access while one threat is using at any given time because data will be manipulate when access line 2, 3 and 4. Critical section Critical section is set of codes access shared resources and there are several ways of developing critical section such as: Locks, Semaphores, Monitors and Messages. In this report will describe locks and semaphores how behave and how priority will work. Locks in synchronization First method of synchronization is locks. Locking is a very primitive system been used. Lock will lock the threat in the critical section while it is processing the record. Mainly lock has two stats Held and Not Held. At the Held state, one threat is in the critical section and at the Not Held state no threats in the critical section and can prioritised threats to have access. Also locks having two operations Acquire and Release. Which threat will request the lock to be held to access critical section and once threat previously use critical section release the lock acquired thread will get a chance and change the state as held. When threat finish it process in the critical section must release the lock to use by the other threats which are waiting in the queue. Figure The above figure has explain how acquire and release will behave at the critical section access, i.e. threats A, B and C request access permission to critical section at the same time by Acquire operation and threat A will grant access with the lock Held state enable. Once threat complete the process will call release operation to change the lock state to Not Held and lock will change state to Held with threat B and so on will be proceed to complete different threat request at the critical section. By using previous example take a look where to use Acquire and Release operations threat. int withdraw (account, amount) { acquire (lock); // Request lock to held to access critical section int balance = account.balance; balance -= amount;Critical Section account.balance = balance; release (lock); // Release lock after complete critical section access return balance; } With further explanation considering previous withdraw and deposit situation Figure 2. Overcome concurrency situation had occurred while both people access same account balance to manipulate the amount. Figure When implement locks use Boolean variable to check is lock held TRUE or FALSE? Acquire operation will keep other threats in the waiting state while lock held values is TRUE. If lock held VALUE is false, will change to TRUE with requested threat. When the threat completed process in critical section will call release operation and change lock held value as FALSE to make lock available for other threats will show in below construct. First create a global Boolean type variable held values TRUE or FALSE to check is lock holding by a threat or not and by default lock will not hold by any threat and value will be FALSE. structure lock { bool held; // initial value FALSE } Construct acquire by requesting a lock to be held and if lock à ¯Ãâà held value TRUE request threat will wait in the queue for lock to be released. If lock à ¯Ãâà held is FALSE and by acquire change value of lock à ¯Ãâà held to TRUE and take the control of the critical section access. void acquire (lock) { while (lock à ¯Ãâà held) ; // Hold other threats in the wait queue lock à ¯Ãâà held = TRUE; // Once get the lock, change lock value to TRUE } Construct release operation simply will change the start of lock à ¯Ãâà held value to false and allows other threat to access critical section for the next process. void release (lock) { lock à ¯Ãâà held = FALSE; // When complete process in the critical section, change lock value to FALSE } Semaphores in synchronization This is the second method of synchronization. This method is a very basic and powerful mechanism but difficult Implementation method and use blocking threats to access critical section instead of locking threats while using critical section. Semaphores has two operations and they are: wait (semaphore) or P() First of all as soon as threat request access permission P() or wait (semaphore) will decrease the counter values which is 1 by default. Then check is counter value become 0 or signal (semaphore) or V() Once a threat complete process in the critical section will call V() or signal (semaphore) and will increase counter value by 1. i.e. if a P() had decrease counter value 0 while it was in critical section and no other threats can access, but second threat has decreased to -1 while requesting permission to access critical section and waited. Also since second threat is still waiting to get permission it goes to sleep mode, hence V() will wake up threat in a sleep to start it process in critical section explains in Figure à ¢Ã¢â ¬Ã ¦Ã ¢Ã¢â ¬Ã ¦Ã ¢Ã¢â ¬Ã ¦Ã ¢Ã¢â ¬Ã ¦Ã ¢Ã¢â ¬Ã ¦Ã ¢Ã¢â ¬Ã ¦Ã ¢Ã¢â ¬Ã ¦Ã ¢Ã¢â ¬Ã ¦Ã ¢Ã¢â ¬Ã ¦Ã ¢Ã¢â ¬Ã ¦Ã ¢Ã¢â ¬Ã ¦Ã ¢Ã¢â ¬Ã ¦Ã ¢Ã¢â ¬Ã ¦. Figure à ¢Ã¢â ¬Ã ¦Ã ¢Ã¢â ¬Ã ¦Ã ¢Ã¢â ¬Ã ¦Ã ¢Ã¢â ¬Ã ¦Ã ¢Ã¢â ¬Ã ¦Ã ¢Ã¢â ¬Ã ¦.. Figure Readers/Writers synchronization This is another powerful method of synchronization. In this method, the data is accessed by two different ways. Those two ways are, readers and writers. Here, the readers only read files and writers update file contents or data. There are four (4) rules while using the readers/writers synchronization methods and they are as follows, If any reader(s) read the file and no writer is pending, the next reader can read the file without waiting. Writers have to wait till the reader(s) finish reading file. After readers finish reading, writer(s) will can start writing. If any writer is writing to the file, acquiring readers have to wait till writer finish writing. If one writer is writing to the file and if both readers and writers are waiting, at this situation priority will be given for writers who are waiting. Therefore readers will wait till all writers to compete writing and then readers will start reading. So readers can read most updated file. Future trends of synchronization In the current situation, locks and semaphores are widely used in order to prevent the concurrency. So it is very important to deal with the codes in critical section as otherwise there will be a lot of problems with the reliability of information systems. However using of systems with the locks are not time efficiency. So in the current situation of the computer technology, there is a trend of implementing lock free systems. According to the previous example of shared street, the shared street has to be controlled by using traffic lights. So on the shared streets, only one direction is allowed at one time. So the other directions are blocked at the same time. But there is a technique that does not need of using any traffic lights on the shared street. Here, fly over technique can be used and avoid blocking the directions. So all the directions on the shared street can be used at once without having any problem. But here, this technique may has some more waiting time as the length of the street can be increased while using fly over technique. Like in this example, lock free systems can be implemented in information systems. Semaphore method can be taken as an example for lock free system. But here as well, the processes have to wait sometimes as in the give example of fly over technique on shared streets. The weakness of this method is that lock free and wait free features cannot be implemented in the same information system. So only one of these methods (lock free or wait free) can be implemented in information system.

Increase in Tuition :: Education Argumentative Papers
Increase in Tuition Dear ISU Cyclone Family Member, Would you like to save yourself $300 to $900 every six months for four years? Maybe go treat yourself to something nice each month or save up and give yourself a big treat at the end of four years? Would you like to see ISU continue with low priced high quality education? These two things will be intangible if you turn and look the other way on this issue. This week Iowa State is hosting the Board of Regents in the Sun Room of the Memorial Union. The Board of Regents will be meeting to discuss and vote on an increase in tuition beginning the 2001, fall semester. A 9.9% increase is on the floor. This increase would put a heavy drain on all present and future ISU students financially. It is critical that this 9.9% increase be struck down. The citizens of Iowa should not have to pay another increase. This enormous percentage is too much to ask. The Government Student Body (GSB) has developed a proposal that will increase tuition, but does not increase tuition at such a drastic increase. (See enclosed sheet for more information.) GSB and other Iowa State students and family are asking you to join them at the Board of Regents meetings to express our dissatisfaction in this possible increase. The dates for these meetings are: Wednesday, October 18 And Thursday, October 19 From 9 am to noon The more representation, the better the chance of the 9.9% tuition increase being denied. Come defend and protect yourself from a tuition increase that is extreme, too expensive, and too high. Enclosed is an information sheet on the tuition increase to inform you of what is really going on and why. Sincerely, Jeanine Farnen Tuition Increase Informational Sheet Do you have $300 to $900 extra to give away? The Board of Regents thinks you do! The proposed tuition increase at Iowa State is out on the table. The increase would be 9.9%, or an extra $300 dollars per semester for in-state students, and $900 additional for out of state students (Iowa State Daily-Opinion). For a student getting their undergraduate degree at ISU that is an additional $2400 for in-state students during their four years at Iowa State; and that is an additional $7200 for out of state students during their for years. Last October the regents approved a 4.3% increase in Iowa tuition. Why another increase? The urgent need for the tuition increase is due to a cut in funding to the Regent Universities from the Iowa State Legislature.

Letter From Friends Essay
We arrived at our destination a few days back, you might have heard of it. Itââ¬â¢s that ranch near Soledad, I think u worked about 5 mile south of here a few months back.

15 Things You Should Never Say at Work
15 Things You Should Never Say at Work Ever wonder what sets successful people apart in the workplace? They always seem to stand head and shoulders above the fray. Part of that is class and style. And part of that is knowing what to say, when to say it, and- more importantly- what not to say. Hereââ¬â¢s a list of 15à thingsà you shouldà never sayà in the workplace.1. Anything that remotely seems like gossipGossip is no good. It takes your focus and energy off doing your best work and can also be seen as petty and vindictive. Keep your eyes on your own desk and life and watch your social capital rise.2. Anything that seems like an excuseIf you canââ¬â¢t do something, donââ¬â¢t offer. And constant apologizing for being late or disrupting meetings? That only draws attention to the fact that you screwed up in the first place. Instead, donââ¬â¢t screw up. Make it a personal policy never to be late.3. ââ¬Å"Noâ⬠Successful people are a little bit fearless, and a lot ambitious. They may not always make g uarantees, but they donââ¬â¢t immediately say ââ¬Å"noâ⬠either. Try, fail, try harder. Fail, fail better. Succeed.4. Complaints about the systemIf youââ¬â¢re bumping up against the work system and itââ¬â¢s curbing your style and your potential, ask yourself first if that particular obstacle is there for good. If it is, put your brain into figuring out how to work around it. If it isnââ¬â¢t, try to change it. Complaints wonââ¬â¢t help in either case.5. Complaints about workloadMore work = more achievement = more success. Never complain about how much work you have. Get it done, then ask for more. And do it because it is a joy to do it, and to set yourself apart.6. Personal stuffSuccessful people keep work talk on work. Itââ¬â¢s less complicated and more productive. And they can remain a bit of a mystery.7. Anything that makes you seem negativeDonââ¬â¢t be mean to your colleagues. Donââ¬â¢t tease them. Donââ¬â¢t be petty. Donââ¬â¢t engage in gossip . Keep your head above the fray and be nice to your colleagues and underlings. Avoid controversy. Keep your good name squeaky clean.8. Money stuffNever brag about your salary. And donââ¬â¢t show off your fancy toys. Stick to encouraging equal footing among your colleagues, and value talent, productivity, and hard work. Keep talk of money out of your office entirely.9. Your goalsSuccessful people rarely broadcast their goals. It not only adds to the pressure on them to achieve them, it keeps them from unnecessary scrutiny. And when they do succeed, the degree of their accomplishment gets to take people by surprise.10. ââ¬Å"Me, me, meâ⬠¦and more about meâ⬠¦Ã¢â¬ The best way to win people over is not to constantly talk about yourself. Listen and show genuine interest in your coworkers. Win hearts subtly and be genuine. Itââ¬â¢s not all about you.11. ââ¬Å"I might just give upâ⬠Successful people donââ¬â¢t even consider giving up. They think outside the box and find another way. But if they do consider it, theyââ¬â¢d never say it out loud. Not even to themselves. Devote your energy to finding solutions.12. ââ¬Å"I know enoughâ⬠Successful people never say no to a learning opportunity. And they donââ¬â¢t feel bashful about admitting what they donââ¬â¢t know and allowing someone to teach them. A strong desire to learn is what keeps successful people on top of their personal wave.13. ââ¬Å"I canââ¬â¢t helpâ⬠Successful people arenââ¬â¢t ashamed to ask for help when they need it. And they always try to help someone out when they are asked for help. This is a great networking strategy as well.14.à Anything just for the sake of kissing up to someonePleasing other people should never be your motive. Be excellent. Be genuine. Win people over with your best qualities, not some idea of what you think they want to hear. And avoid trying to take shortcuts or sweeten up the boss by any other means. Thatââ¬â¢s transparent and wonââ¬â¢t reflect well on you.15. Offensive jokesOffensive comments are wrong, but so are offensive jokes. Something offensive said in jest is still offensive. Donââ¬â¢t be rude. Be sensitive to the needs and feelings of others. And keep control of your emotions; that will keep you above the fray.

Top 4 Skills That Will Make You Eternally Employable
Top 4 Skills That Will Make You Eternally Employable There seem to be four things that set people apart from their peers throughout the course of their careers. Most job success comes from constant development of yourself as an employee and also as a leader. To help yourself along this path, itââ¬â¢s always a good idea first to assess your strengths and career personality. Once you have a good sense of your strengths, youââ¬â¢ll be able to take on greater responsibility, identify and correct your weaknesses, and take the risks that will help you grow in your life and your career. Youââ¬â¢ll be able to work to develop the key traits of courage, authenticity, and humility. Youââ¬â¢ll learn to be confident, not arrogant. And youââ¬â¢ll find yourself getting rewarded and recognized for the good work youââ¬â¢re doing.There are four core skills that will make you eternally employable:Executing, orà making things happen. Sure, everyone can have great ideas, but do you have the drive and energy to get it done?Influencing, o r reaching a broader audience for yourself and as a team. Do you have the personal skills to reach out and hype people up in order to make a change or complete a project in the best way possible?Relationship Building, or networking and holding your team together. Companies are looking for people who they donââ¬â¢t have to worry about. Are you good in a group? Do you have the ability to assess who is good at what tasks, and then motivate them to get the job done?Strategic Thinking, or looking to the future and always thinking about possibilities. All companies want to grow. If you want to get hired, itââ¬â¢s up to you to prove you have the ideas and creativity to take the current level and kick it up a notch (or two).These four strength categories cover a wide range of smaller strengths, but can be extremely useful in developing your self in your career. Remember, people can and do succeed with two out of four. But great leaders are strong on all four fronts. Try working to bui ld each category up as often as you can and see what a difference it can make in your life and on the job.

The Breakup of the Eurozone is inevitable within the next five years Essay
The Breakup of the Eurozone is inevitable within the next five years. Discuss - Essay Example Countries in the Euro zone are restrained from pursuing their self- interest by mutually respecting each otherââ¬â¢s sovereignty and independence rights. However, Euro zone must adhered to EMU operating principles. Good governance must be practice at all transactions to avoid future crisis2. January 1, 1999 saw the official launch of the Economic and Monitory Union (EMU). On that day, eleven European countries joined the EMU and five more followed suit years later. Now, EMU is comprised of sixteen member European countries. The first to join were Austria, Belgium, Germany, France, Ireland, Italy, Finland, the Netherlands, Portugal, Luxembourg, and Spain. Greece followed in 2001, then Slovenia in 2007 while Cyprus and Malta joined in 2008. The last to join was Slovakia in 2009. EMU countries adopted Euro as a single currency for transaction purposes. The chief reasons that lead to EMU were mainly to stabilize prices, macroeconomic environment, banking system, financial markets as well as increase trade competitiveness and boost flexibility in the member countries3. Before and after the official launch, different people had different views concerning the sustainability of the Euro Zone especially on areas of viability and desirability. Supporters of EMU claimed that commo n currency has the potential to improve trade, attract more foreign direct investment, stabilize wages and enhance business strategies of member countries. On the contrary, they are opponents who predict that Euro zone is heading for a disaster4. They pegged their arguments on the premise that countries in the Euro Zone are diverse and put individual interest forward at the expense of the EMU. There are benefits and costs associated with Economic and Monitory Union. If costs are more than benefits, EMU may not survive in future and if vice versa, union will endure the test of time. The first advantage is that common currency reduces costs

Updating Computer Operating System Research Paper
Updating Computer Operating System - Research Paper Example Upgrading computer operating system means adding the latest versions of computer programs to run the computer with more speed. It includes updating in software and in hardware of the system. Updating in software system means to install advanced enhancements over old versions, whereas an upgraded hard drive enables the computer system to perform in a better way (Wempen, 2002). It is important for every user to maintain and upgrade the personal computer. Computer upgrading process analysis approach includes the following steps: 1. Arranging: Arrange a back-up for all important records to any other hard disk. It is important because if a problem occurs during the upgrading process, there is a risk of losing some or all data of the computer. Defragmentation of the hard disk is another important task because it helps the computer to read fragmented files more efficiently which are located in different areas. These files can slow down the speed of computer functions (Thompson & Thompson, 2 006 ). In order to install a new operating system, a new folder should be made. Until you are sure that everything is working perfectly on the new operating system preserve your whole data of computer into another windows directory.
