Question: Talk about theTopics in Ethics for Truck Companies and Hotels. Answer: Presentation: One of the most noteworthy divisions of the Australian Economy is the vehicle and the coordinations part. It is evaluated as an estimation of a measure of $95.4 billion. In the year 2015-16, it was liable for including a measure of $39.26 Billion to the Australian Economy. A greater part of the residents of Australia are subject to the vehicle business and even a little change will undoubtedly influence the business, the residents just as the general economy of Australia and it is will undoubtedly prompt noteworthy impacts. Practically a large portion of a million people are utilized in the divisions of coordinations, street transport, warehousing just as stevedoring. The class of people getting generally influenced by the change are the truck drivers and the associated organizations. Organizations like the truck organizations, inns and comparable undertakings would be profited by these changes. This is on the grounds that they would pick up the most extreme measure of benefits in view of the cost decrease. The issues would be looked by the ordinary individuals in any case, and they would lose their customary positions due to such innovative turns of events (Sanchez, 2015). Utilitarianism Theory: A demonstration of utilitarianism is what gives the most extreme measure of utility to a more noteworthy number of individuals. It is then viewed as ethically right or reasonable as the results of the activity are will undoubtedly be acceptable. It is normal for each person to have an own decision or the usual way of doing things of performing anything in their lives. There will undoubtedly be a response to each activity too. In this manner it is important to have a determinant of value to find out the results. The utility hypothesis can be characterized as something that an individual feels in the event of something he achieves. It would thus be able to be said that the best activities end up being gainful for a larger part of the individuals while antagonistic activities sway the individuals adversely and furthermore cause them to endure (Scanlon, 1982). A bigger portion of the populace would be influenced by the Driverless Trucks which is essentially a specialized headway. This is on the grounds that a lot of employments would be lost hence. It tends to be said then again that this circumstance would make a specific more extravagant fragment of the populace upbeat. It was during the mechanical move towards the idea of the driverless vehicles that the economy would be affected. This would be because of the move towards the driverless vehicles. Gigantic measure of enduring is because of the joblessness of the individuals. So the antagonism ought to be forestalled however much as could reasonably be expected to stop the affliction and keep away from it as much as should be possible (Smart Williams, 1973). Dominant part of the individuals should be shielded from such sorts of pessimism. The types of abuse and worker misuse ought to likewise be halted. The rising interest of employments ought not be refered to as a reason for such abuse. Poor administration represents the mishaps (Donaldson Dunfee, 1994). Deontology Theory: Hypotheses like Utilitarianism just as consequentialism are restricted by the hypothesis of Deontology. It isn't worried about the result of the activity and just is made a big deal about the ethical commitments, which is its significant contrast with different hypotheses as they are stressed over the results. Certain standards are determinant of the decisions of the ethical quality. One of the ethical commitments of extremely individual is the deontology hypothesis. This hypothesis needs an individual to keep the standards and the guidelines without making a big deal about any kind of results. It regularly happens that organizations orchestrate the approaches aiding the guideline of the expenses for long haul benefit expansion. The outcomes ought not be stressed over in these unique situations and standards ought to be carefully clung to in this association. Contingent upon the standards and their correspondence, the driverless trucks can be viewed as paying little mind to the loss of employments and even the conceivable outcomes of mishaps. This doesn't consider the activity misfortune caused due to the operational change. The obligations and the ethical commitments are obediently satisfied in the deontology hypothesis. Ethicalness Theory: This hypothesis is worried about the idea of reasoning ethically and morally. The activities of the people should be appropriately investigated dependent on the moral methodology and consequently the individual attributes are the significant parts of reasoning morally. The plausible good temperances that are found in people incorporate those of attentiveness, sympathy, liberality, benevolence, charity, supportiveness. The ideals and individual has are determinant of a people character. So as to be ethically right, every individual needs to comply with these standards. It can unmistakably be said in this association that the presentation of driverless trucks is totally untrustworthy as in this situation the rich are more worried about their joy than the circumstance of those people whose lives are reliant on the truck drivers just as the drivers. The progression of the driverless trucks is totally against the specific qualities, for example, mindful, thought, liberality just as the thought of the individuals who are influenced by loss of occupations (Zagzebski, 2010). Agreement Theory: Agreement hypothesis is worried about things that take a shot at authoritative premise. It is essentially the agreement between the operator and the chief guaranteeing their trust with an understanding. It is fundamentally a financial wonder which helps in the investigation of the legally binding understandings of various gatherings in the general public they live in. The agreement hypothesis likewise helps in keeping up a hole between the events and the desires. The hypothesis likewise includes a calculation which brings about a superior choice aiding in the amplification of a result. This hypothesis is worried about everything which is managed without the separation of any kind of value. Just in circumstances in which people are given the best possible offices, he will know about the profound quality just as will keep up great conduct and attributes. The various sorts of business would be worried about clear standards just as rules of working. The utilized principles would help maintaining human rights just as the privileges of jobs. On the off chance that it is discovered that there are any sort of changes the truck proprietor or driver assumes the liability as per the conditions of the agreement. On the off chance that the workers just as the organizations keep up the pre characterized rules and guidelines, at that point the presentation of the driverless trucks may prompt the infringement of the rights. It may likewise cause mishaps and deadly events. End: The speculations talked about above express the positive just as the negative hypotheses of the driverless truck innovation. The hypotheses that advocate the privileges of the more prominent populace are Utilitarian hypothesis, authoritative hypothesis, and goodness hypothesis. These hypotheses express that on the off chance that the quantity of occupations is extremely low or nil, there is no degree for the privileges of the individuals. The main hypothesis that doesn't consider the outcomes of the presentation of driverless trucks is the deontological hypothesis. It can't be overlooked that the presentation of the driverless trucks would cause loss of enormous number of occupations of the drivers of the side of the road, gas stations, transport, bistros and so on. The persevering individuals clearly need employments of a similarly better quality on the off chance that they lose their current positions. It would thus be able to be inferred that everyone's benefit of the populace should be remembered while managing the innovative progression. References: Donaldson, T., Dunfee, T. W. (1994).

Answer 3 history questions - Essay Example Be that as it may, Lincolnââ¬â¢s resilience in the issue was censured by the Radical republicans who were of the nonattendance of any Black social equality in the Presidential Plan. After all the Blacks were liberated after the Civil War, the Radicals were presently requesting more prominent rights for them as equivalent Americans. Abraham Lincoln was the killed in 1865 after which President Andrew Johnson passed lawmaking bodies in the Southern states which constrained the privileges of Blacks to a lot of codes. Subsequently, the period under the organization of President Johnson saw laws confining Black rights and supporting the mastery of the Whites (Public Broadcasting Service a, n.pag.). Alongside help from President Johnson and his prohibitive Black codes, the Southerners attempted to keep up subjugation generally. Outrage emitted in the North against the out of line dark codes detrimentally affecting the help for the Presidential Reconstruction.

Asking Friends and Family to Embrace Change
Asking Friends and Family to Embrace Change Change isnât easy. More often than not, we donât change because we get in our own way. Other times we donât make a change because weâre afraid of what people will think about us, afraid of what they will say about us, afraid they will treat us differently. Ultimately, we are afraid of rejection. When we approached minimalism, we realized many of our closest friends and family members were supportive of the changes we wanted to make; and in other cases, many of them were neutral bystanders, ambivalent to the simplification going on around us. In some instances, some of the people closest to us didnât approve of our new paths: some of these people mistook the journey on which we were embarking as a direct attack on their way of life, as if by questioning our lives we were also questioning their lives. Clearly this was not our intent: our journey involved questioning our lives, not theirs. We were simply looking for happiness, using minimalism as a tool to search for deeper meaning. Yet some people thought the changes we were making were silly, stupid, and even crazy (literally). We had worked hard for more than a decade to accumulate all these nice material possessions, big houses, fancy cars, âimportantâ job titles, and the American Dream, all of which was supposed to make us happy, right? When the consumerist, over-indulgent lives we were leading didnât make us happy, there had to be something wrong with us. At least thatâs what the naysayers said: Maybe Joshua Ryan went crazy. Maybe they are experiencing a mid-midlife crisis. Maybe they joined a cult (someone actually accused us of joining a cult, likening minimalism to Jonestown and Branch Davidian). We had to explain a few things to these naysayers Itâs not you, itâs me. Weâve all heard this line before. It has been parodied a thousand times, but there is a profound truth to be discovered here. We werenât questioning anyone elseâs lifestyle but our own. Many people werenât happy with their own situations, and they aspired to be like us because they thought we âhad it figured out.â We didnât have it figured out, though, and that frustrated some people because we were who they wanted to emulate: we had the material possessions, the salaries, the awards, the facade of power, the fast-track to corporate success. We looked around us, though, and realized most of the people above us, people several rungs higher on the corporate ladder, werenât happy, eitherâ"they were far less happy than we were. What were we supposed to doâ"keep working exceptionally hard and aspire to continue to be unhappy? Itâs all right to tell naysayers youâre making changes in your life so you can be happy. Better yet, you can do wh at we did and ask those naysayers a question: âYou want me to be happy, donât you?â Circumstances change. If our 28-year-old selves could have time-traveled back to 1999 to tell our eighteen-year-old selves about everything we were going to âaccomplishâ over the next decade, the teenage Joshua Ryan would have been elated. You mean Iâm going to have this, that, and this? You mean Iâll be able to afford this? The happiness would have soon faded, though, and by 28 (or perhaps much sooner) an overwhelming cloak of discontent would have enveloped our lives. Thatâs because circumstances change, and thus, we must change: we must continue to evolve and grow if we expect to be happy. What adds value to your life today, may not add value to your life tomorrow. You, too, can change. Minimalism may not be the answer for you. If youâre not happy, though, you, too, can build your change muscle and, over time, change your circumstances. There are many paths to happiness; minimalism simply allowed us to clear the clutter from our paths so we could find that happiness sooner. Show people the benefits. As we journeyed further down our paths, many of the naysayers jumped on board. Not because we asked them toâ"weâve never asked anyone to embrace minimalismâ"but because they saw the happiness weâd welcomed into our lives. They saw that for the first time in our adult lives we were truly excited, joyous, and content with who we were. They saw that perhaps we didnât have it figured out before, and maybe we didnât have it figured out now, but we certainly appeared to be on the right track. The actions alone didnât convince them, but once they saw the benefits, they better understood the changes weâd undergone. There were, however, some relationships we had to get rid of: it wasnât easy, but certain peopleâ"friends and familyâ"werenât adding value to our lives, they were sources of negativity, and they prevented us from growing. We treated this option as a last resort, but itâs important to know that, as we grow, even our relationships can change. Today, many of our old friends are still our friendsâ"while others are notâ"but weâve also established new, empowering relationships that encourage our constant growth and help us enjoy what we contribute to the relationship.

The Role Of Schools In Early Childhood Education - 1022 Words
The role of schools in early childhood education is that they should present high quality free and universal education. Schools should be providing children with the opportunity to attend Pre-K as well as Kindergarten. According to Erlbaum (1983), ââ¬Å"Children who attend preschool are less often retained in grade and placed in special education, and they more often graduate from high school.â⬠Enrolling a child in a Pre-K program introduces children to the academic skills that are a necessity when transitioning from Pre-K to Kindergarten and the academic years to come.

Literary Analysis Of The Cranes - 1467 Words
Caitlin Porter Mrs. Sondag IB Language September 29, 2017 Literary Analysis of ââ¬Å"The Cranesâ⬠To love and to be loved is one of the most powerful ideas that is desired by so many within society. True love is something that many people hope to find, but very few are actually successful. While it may be difficult to discover this within our own lives, literature has developed its own role regarding love stories within society. Everyone is drawn to a good love story, a love story that leaves a lasting impression on the reader. Take Romeo and Juliet, while the play was wrote so long ago, the impression had lasted a lifetime all because of the love story that it told. All throughout history this has been taking place and there hasâ⬠¦show more contentâ⬠¦But whooping cranes, theyââ¬â¢re rare. Not many leftâ⬠( Meinke 5-6). The man was not only referring to the birds during this time but also his love for his wife. As they continued to watch the birds they began reminiscing on their younger years together. ââ¬Å"She turne d her head from the window and looking into his eyes. ââ¬Å"I never got tired of listening to you.

This a love that is unconditional, a love that is true. A love that continues to love with everything that they have no matter what. A love that never gets tired of the other, even if theyââ¬â¢ve been together for countless years. A love that is rare, like the whooping cranes.

Slavery in Brazil Free Essays
Edmund Burke, the acclaimed author and philosopher once said, ââ¬Å"Slavery is a weed that grows on every soil. â⬠Between the 16th and 19th century in the Americas, millions on millions of slaves were brought to the New World. There purpose was to work. We will write a custom essay sample on Slavery in Brazil or any similar topic only for you Order Now The economy of most European colonies in America was dependent on slaves. The land that was discovered in Americas was useless with out sufficient slave labor to exploit it. In this essay, I will focus on two nations where slavery played an enormous role in the development of that country. First, The United States, where in 1860 in South Carolina over 50 percent of the population were slaves. Next, Brazil, the nation where about one third of all salves from Africa were brought. In this essay I will compare slavery in The United States to slavery in Brazil, I will dissect the similarities and differences while focusing on why and how the slaves came, the demographic and religious aspects, the treatment of the slaves, and the aftermath on both countries due to slavery. Around the year 1530 the Portuguese came to Brazil in search of land and natural resources, specifically sugar. As the Portuguese and the indigenous people of Brazil battled for land, the Brazilians resisted against being enslaved. As the Portuguese presence grew in Brazil so did disease, causing the death of most of the working indigenous people. As the number of sugar plantations grew, the demand for workers did as well. This is the main reason why Brazil began to import slaves from Africa. Although the origin of slaves in The United States was similar to Brazil, there were some differences. In the year 1619, only around 10 years after the British began to colonize US, a Dutch slave trader exchanged about 20 Africans for food in Jamestown, Virginia. Like Brazil, the U. S needed workers for plantations, but while Brazil focused on the sugar plantations, the U. S was focused on the tobacco plantations. In general, both Brazil and the U. S lacked a major resource in order to maintain a strong economy, that resource being workers. Although Brazil used more slaves towards sugar and the U. S used more towards tobacco, in general the slaves worked in mines or they worked in a sugar, rice, tobacco, or cotton plantation. Although the U. S played a larger role in the process, both Brazil and the U. S participated in the Triangular Slave Trade. Some say the Triangular Slave Trade is the reason why 10 to 15 million of Africans were shipped to the Americas between 1650 and 1860. The slave trade was simple yet wrong on so many levels. The slave trade took several different routes, but there were two popular ones. The most common route would first start in Europe where the Europeans would trade manufactured goods for slaves in Africa. Next, the slaves were transported across the Atlantic Ocean to Brazil and the Caribbean where the slaves were sold for huge profits or traded for sugar, coffee, and tobacco. The journey from Africa to the Americas was known as the middle passage. Olaudah Equiano was a slave captured and sold into slavery. In his book, The Life of Olaudah Equiano the African, when describing the middle passage he writes, ââ¬Å"I was soon put down under the decks, and there I received such a greeting in my nostrils as I had never experienced in my life; I became so sick and low that I was not able to eat. I now wished for the last friend, death, to relieve me; but soon, to my grief, two of the white men offered me eatables; and, on my refusing to eat, one of them held me fast by the hands, and laid me across, The white people looked and acted, as I thought, in so savage a manner; for I had never seen among my people such instances of brutal cruelty. The closeness of the place, and the heat of the climate, almost suffocated us. The air soon became unfit for respiration, from a variety of loathsome smells, and brought on a sickness among the slaves, of which many died. The shrieks of the women, and the groans of the dying, rendered the whole a scene of horror almost inconceivable. As you can tell, the conditions were brutal to say the least. Another popular triangular route taken was ships from the U. S colonies would take rum and other products to Africa in exchange for Slaves. From there, the slaves were taken to Brazil and the Caribbean and sold for profit or sold for sugar and molasses to take back to the U. S where then the sugar and molasses was sold to rum makers. In general, the slave trade was horrific and inhumane, however, it is the reason that the U. S and Brazil were able to maintain a steady economy. Although there were many similarities between the Brazilian slaves and the U. S slaves, there were quite a few specific differences as well. One of the largest differences in slavery between Brazil and the U. S was demographic. Generally speaking, the Brazilian slaves were usually decreasing while the U. S slaves were usually increasing. This is due to several reasons. First, the Brazilians had a much lower proportion of female slaves compared to the U. S who had an equal sex ratio. In Brazil, due to the lack of female slaves, they had a much lower birth rate then the U. S did. Both the death rate and suicide rate was also higher in Brazil compared to the U. S. Due to the low birthrate and the high death rate, Brazil had trouble to maintain a population resulting in having to continuously import slaves. On the other hand, the average number of children born to an early 19th century U. S slave woman was 9. 2; this is twice as many as Brazil and the Caribbean. All these reasons are why Brazil had a much larger number of recent arrivals from Africa while the U. S had a predominately American slave born population. Also, this is why out of the millions and millions of Africans who were brought to the New World, over one-third landed in Brazil and between 60 and 70 percent ended up in Brazil or the sugar colonies of the Caribbean. According to Henry John Temple, the well-known British Prime Minister of the 19th century, he suggests that there were about 3,000,000 slaves in Brazil in the 19th century. Although it is hard to know the exact number, most historians agree that it was around 3,000,000, which would be about forty percent of the whole population. On the other side, in 1860, the slaves in the U. S were only about 13 percent of the entire population. Generally speaking, in Brazil slaves worked on much larger plantations then in the U. S. Most Brazilian plantations held about 150 slaves per plantation. In the U. S, it was quite different. According to Carl Deglar, who wrote, Slavery in Brazil and the United States, he states, ââ¬Å"Out of all the plantations in the U. S, more the half the slaves worked on units with 20 slaves or less. â⬠In the U. S it would not be uncommon for the slaves to deal with their owners on a daily basis, while in Brazil some worked on plantations with hundreds and hundreds of other slaves where it would be rare to encounter your owner. When comparing Brazil and the U. S today, the demographic differences during the days of slavery is one of the main reasons why the two countries are so different One may think that since the slaves were brought to the U. S and Brazil for similar reasons then they all were treated the same, had the same rights, and were viewed the same. Although this is by no means entirely false, there are a few specific differences on how the slaves were treated in the US compared to how the slaves were treated in Brazil. Religion among the slaves was vital for some while non-existent for others. In the U. S, religion was discouraged for the slaves. The average white American slave owner thought there was no need to ever have a slave practice a religion. This could be due to the fact that nowhere in the Catholic Christian teachings does it say itââ¬â¢s acceptable to enslave and treat a fellow Christian as the owners were treating their slaves. In 1831, Virginia passed a law stating, ââ¬Å"Slaves and free Negroes were forbidden to preach, exhort or teach in any prayer-meeting or other association for worship where slaves of different families are collected together on penalty of not more than thirty-nine lashes. In Brazil, the Christianity of a slave was viewed quite different. Some slave owners even viewed it as an essential for a slave to work on his farm. In some cases the slaves would even have to perform a religious ritual even before they stepped foot in Brazil. Instead of being viewed as complete property, the slaves in Brazil were given a chance to practice a religion, in pa rticular, practice the teachings of the Catholic Church. The slaves that departed from Angola, Africa to Brazil were baptized before they got on board the ship. When they arrived in Brazil, the slaves were acknowledged as baptized and had to begin learning the prayers, doctrines, and functions of the Church. In Brazil, marriage was actually acceptable and valid. In 1711, the Constituicoes Primeiras of the Archbishopric of Bahia reaffirmed the legitimacy of marriages between slaves, and between free persons and slaves. According to the Constituicoes, masters could not prevent their slaves from marrying, nor could they separate them once they had wed. Although this may sound promising, it sounds better then it actually was. Most slave owners did not abide by the law that you could not separate a married slave. In general, they still viewed them more as property then people. According to Fernando Henrique Cardoso, the former president of Brazil, he states, ââ¬Å"Of the 660,000 slaves in all of Brazil in 1875, who were 14 years or older, only about 1 out of 6 was recorded as married or widowed. â⬠In terms of religion, it is true that the Brazilian slaves had more rights then the U. S slaves, but not by much. As you can see both the U. S and Brazilian slave owners were more determined on making profit by making the slaves strenuously work then anything else. Although both Brazil and U. S slave owners had complete ownership and control over their slave, the way they treated them did differ between countries. Theoretically, both Brazil and the U. S had laws against murder, abuse, and over working the slave. The difference is, generally speaking, in Brazil some of those laws were carried out while in the U. S, it was rare to see anyone ever defend a slave. In the U. S, the slave owner acted as the judge and jury for any issue involving his slave. In Brazil, a slave had somewhat of a right to a jury. For instance, say a slave owner murdered his slave in the U. S. In most cases it would go unheard of, but even if it were taken to court, it would have been extremely rare if the owner were prosecuted for anything. Now, if a slave owner murdered his slave in Brazil, by law the court should have prosecuted the case as if the slave was a free man. Although it may sound that slavery in Brazil was a lot less harsh, in reality, this judicial approach in Brazil is what should have happened, but as you can guess, it rarely ever did. Henry Koster, a famous German author and film director, in his novel, Travels to Brazil, he states, ââ¬Å"occasionally a cruel master was fined for maltreating his slaves but, I have never heard of a punishment having been carried farther then this trifling manner of correction. â⬠Although by law, the Brazilians compared to the U. S had stricter laws protecting the slaves, when it comes down to the truth, in both countries the slave was viewed more as property then human, mistreating your slave was seen as mistreating your property. One of the biggest differences when comparing U. S slavery to Brazilian slavery concerns manumission. Manumission, meaning the act of freeing a slave, was undoubtedly less common in the U. S compared to Brazil. The number proportion of free slaves in Brazil compared to the number proportion to free slaves in the U. S proves that manumission was more frequent in Brazil. In 1818, for every one free African in Brazil, there were only three slaves. This ratio is compared to with that in the U. S in 1860, when for every one free African, there were eight slaves. By 1872, the number of free Africans in Brazil was more then double the amount that were still slaves. The numbers show that thereââ¬â¢s indisputable evidence to prove that manumission was more frequent in Brazil. It is important to note that Brazilian slave owners were freeing the sick and the old more so then the U. S, however, the sick and the old simply would not have been capable to produce offspring in numbers to explain the large number of free Africans in Brazil. Marvin Harris, the famous American anthropologist, along with many other historians suggests another explanation to why there were such a higher percentage of free Africans in Brazil compared to The United States. As stated before, in Brazil in the late 19th century, the free Africans greatly outnumbered the slaves. The big difference was that Brazil needed those free Africans in order to maintain their economy. The free black slaves in Brazil produced food, were craftsmen, and even slave catchers. They performed the tasks that slave labor was too hard to achieve and the whites thought they were too good to do. This was not the occurrence in The United States. First, the U. S was importing more food rather then growing it like Brazil did, and the food that was being produced in the U. S was produced by whites in the South and Northwest. Also, the U. S had enough white men to perform the tasks that the free Africans in Brazil were doing. Therefore, for the U. S there was no economic reason for the whites to turn towards manumission as Brazil did. It did not matter if you were a slave in Brazil, The United States, Caribbean, Central America, or anywhere else, something that they all had in common was the attempt to run and become a free man. Some succeeding, some did not. In Brazil, escaped slaves formed communities like the ones they were forced to leave in their homeland. These communities were called quilombos. Compared to the U. S, the slaves in Brazil had a greater and a better chance for escape. The number of escaped slaves, the number of revolts, and the size of the quilombos were all greater in Brazil. Although there were plenty of revolts and escapes in the US, generally speaking, there were fewer participants then Brazil. In most of The United States, the climate was to cold in the winter to survive on your own compared to Brazil where the climate was reasonable. Also, Brazil was full of forests to hide in compared to the U. S where the areas were policed heavier. The large quilomobs communities in Brazil may contribute to the fact that today, in Brazil the blacks are seen as Brazilians while in certain parts of The United States, the blacks are still seen as Africans. During the days of slavery, discrimination towards blacks was clearly brutal and ruthless. The horrific and saddest result of slavery in The United States is that race prejudice still exists today. I am not saying that blacks are thought of as they were in the 18th century, but in The United States today, especially in the South, there is still discrimination towards colored people. After slavery was abolished in The United States, by no mean did that make the whites and blacks have equal rights. Even after the abolition of slavery, a black man still could not vote, give testimony in court for a white man, marry white women, hold office, and many other terrible things. Brazil, on the other hand, as writer Herbert Alexander puts it, ââ¬Å"the race problem had been allowed to solve itself. â⬠For example, in the seventeenth century, one of the three main officers when the Brazilians fought the Dutch was Henrique Diaz, a black man. This is something you would have never saw in The United States. The United States and Brazil were one of the last nations to abolish slavery in all of the Americas. The Civil War, which lasted from 1861 to 1865, ended slavery in the United States. In 1888, due to international political pressure, Brazil being the last nation to do it in the Americas, finally abolished slavery. Unlike The United States, Brazil was able to abolish slavery with out catastrophic violence. In both Brazil and The United States, the horrific terror of slavery in the 16th to 19th century is something everyone would want to forget. However, during that time period slavery was the reason why both The United States and Brazilââ¬â¢s economies were both stable and on the rise. Overall, when looking into the history of slavery in both The United States and Brazil, although there are differences and similarities, the time period of slavery explains greatly to why present day life in both unique countries is what it is.

Managements and Organizations
Questions: It is often believed that many companies are emphasizing on creating high performing teams to gain competitive advantage. Do you agree with this statement? Why? Why not? Use examples from your organisation? In answering this question you are expected to define the relevant terms and definitions. Please include the following concepts in your answer: a. Recent popularity of teams; b. Types of teams and c. Creation of high performing teams. Answers: Part A The two types of management frames taken are authoritative and democratic. The authoritative frame of management is power-oriented, punitive and has controlling power with the management. They believe in imposing rules and regulations on the employees and treat the employees as subordinates to the top management authority. On the other hand, the democratic type of management is employee centred; believe in maintaining good relation with the employee and follow participative principle, in contrast to the directive principle of authoritative management. Further, the former is job centred and the later is employee centred. The former is concerned with the production of the company and the latter is concerned with the people of the company. Lastly, the former is task-oriented and the latter is relationship oriented (Drori et al.2013). In todays changing trend of competition, market , customers, slowly and gradually the authoritative managing organization are changing them to democratic m anagement system. Trump organization is a real estate privately owned company of United States that follows authoritative management (Trump.com 2016). On the other hand, Apple Inc. is multinational technology company of United States. The paper discusses the differences of both in operations (apple.com 2016) In case of authoritative management, the top level employees treat the junior employees as subordinates and believe in imposition of rules and discipline. On the basis of that they formulate strategy. Strategies are generally formulated based on the environment of work and in the authoritative management the work environment is conservative and so the strategies are also formed without any integration with the employees. However, in democratic management, the top management believes in including the employees in the decision making and make them free to discuss their issues. Hence it leads to formulation of strategy integrating the employees. Integration of employees in strategy formulation helps in positive implementation of the strategies as the employees themselves are included in making the strategies so they cooperate full heartedly, in its successful implementation (Fleming and Spicer 2014).Strategic integration is a part of democratic management and the key to its success The traditional managers generally follow their traditional style of operation like in Trump, an authoritative firm, whereas, the entreprens believes in implementing entrepreneurial management, like in Apple Inc. In the former case, the manager are suppose to check the work of the subordinates, like checking on staff time, monetary budgets, efficient level of inputs and others whereas, in the latter case, the entreprens prioritise the activities. They focus more on allocation of resources like time and money, purchase of effective services and expertise. The difference in their approach brings different results (Goetsch and Davis 2014). Both the approach is unique in its own way and also successful to their levels. However, chane become inevitable with changing environment. Doing business in multicultural market is a challenge for both the companies. The consumers taste, preferences and demand widely varies in multicultural market as it is influenced with their style of living, religion, eating habits and other factors. Trump being an authoritative firm tries to satisfy the market demand at its own level adopting different strategies but Apple Inc. first tries to understand the culture of the market and treat people individually with customised products and services. Understanding the culture of the market helps in penetrating the market better than being trying its own strategies without understanding the requirements (Nonaka et al.2014). An authoritative firm believes in making their own market strategies without doing sample study of the market which may bring failures sometimes The difference in culture affects the management practices and their policies. In an authoritative management system, if there is difference in the culture of employees and market, their approach of dealing varies as compared to that in democratic management system. The former will not try to gel with the different culture people and will try to impose the companys rule on them, whereas, the latter will try to make the place of work comfortable for the different cultural people so that they can work effectively and meet the activities of their task efficiently. The conservative style of authoritative management does not bring successful returns to the company in todays global economy and the participative management style is more successful in meeting their goals (Roth 2014). The participative management tries to integrate through different culture and style of work which is inevitable in todays global economy framework. Part B Companies do create high performing team to meet the increasing challenges in the market, especially to gain competitive advantage against the competitors. The Trump organization has formed organization work force where the team members together work under the guidance of the manager or leader to achieve a common goal of gaining competitive advantage in the market. On the other hand, In Apple Inc, self managed team are formed to meet the similar goals. In self managed team, there is no supervisor or leader and the team members are individually accountable for their performances and results of the task assigned. In self managed team, each member of the team id its own mentor and guide and is responsible of his or her performance and achieving the common goal. However, in Trump organization, the leader has the responsibility of the team performance and is accountable to the authority when the team performance is not good (Belbin 2012). In every organization no one can work alone and team work is always required, be it authoritative or democratic management. Every employee has to be a part of the team and need to work in coordination with the team to achieve the common goals and to perform well. There are different types of team and can be formed anywhere irrespective of the type of management. They are permanent team, temporary team, task force, committee, organization work force; self managed teams, cross functional team and virtual team. In an authoritative management practice, the type of teams found is generally, organization work force, committee, permanent and temporary team. On the contrary, the type team formed are generally, self-managed team, virtual team and cross-functional team (Belbin 2012). Apple Inc. team performance has given few leanings that must be followed to have high performing team. Firstly, one person should be in-charge of the project and should be accountable for delivering the work of the team. Secondly, the team must meet once in week to update each other about their output and task status. Third, the top level employees should work in team to have the similar teamwork at the bottom level. Otherwise, the team work filters as we move from top to bottom level of employees. Fourth, each member o the team must trust others and should share their problems openly so that solutions can be found and team performance can be enhanced. Fifth, the member of the team should be open to arguments and should not fear getting into conflict. The fear of conflicts damages the team performance and not the presence of conflicts. Sixth, the team member should be given some leverage to take decisions and every decision should not be subject to committee meetings. It makes the em ployees frustrated and they start delinking themselves from the companys performance. Lastly, the team should work to achieve one goal and every member should be united in reaching the goal (Shafritz et al.2015). The Apple Inc. being a democratic management system do follow the above mention criteria to increase the performance of the team. However, Trump organization being a authoritative management system does not believe in all the criteria and maintain control with the management for the team performances (Starr et al. 2016). Part C There are several factors that motivate the investors to invest overseas besides the value of the currencies. In case of Malaysian investors, similar factors have played the role in increasing the investment in Cambodia. The factors are discussed below. In Cambodia, the labour wages are low that reduces the cost of production for the organization. The government policy is liberal on business and has large consumer market. The country has always maintained good relation with the other countries and has entered a number of trading agreements like Association of South-East Asian nations (ASEAN), Asia Free Trade Area (AFTA), and China- ASEAN Free Trade Area (CAFTA). These trading agreements have made the country to have preferential access for a number of products to some of the worlds richest market (Tremblay 2012). Cambodia has one of the most open economies of the world and has been ranked 35th in terms of economic freedom by Heritage Foundation Index of Economic Freedom. The country has received the rank due to its positive policies towards labour market restrictions, trade policy, regulatory barriers and fiscal burden. However, the country do face economic hurdles in terms of limited infrastructure, poor health care, low government salaries and other problems faced by a less developed country. But in respect of doing business, the country has always supported the investors. The country has also topped the rank among other LDCs, in terms of market friendliness (Walker 2015). The areas in which the country excels and has given easy access to business are tourism and agriculture. Country has liberalised its policy sufficiently for the foreign companies to invest in tourism industry which is a growing industry in the country and has enough potentiality for making profit. The visit of tourist is expected to cross 1 million mark in the next two years and hence demand high quality of facility for the tourist which is possible only through FDI flow. The government of Cambodia has provided built-operate-transfer schemes for the investors to attract them to invest in the country. Further, government has helped the MNCs to avail finance from International Finance Corporation (IFC), Asian Development Bank (ADB) and countries like Japan which act as a donor country for Cambodia (Tremblay 2012). Agriculture sector also has lots of potentiality for foreign investment especially in agro-processing and organic farming. Government has provided the facility to the foreign companies to get into partnership with local farmers with 51% share of equity that has definitely attracted FDI in the country (Walker 2015). Hence, though the value of dollar increases and investment becomes expensive, there are other factors that have encouraged Malaysian investors to invest in the Cambodia. References Apple. 2016.Apple.

ghosts of mississippi Essay Example
ghosts of mississippi Essay On the night of June 13th 1963, President John F. Kennedy was giving his speech on Civil Rights.Among the many thousands of people in America viewing this event on National Television were Myrlie Evers and her three children.Suddenly, this occurrence was rudely disrupted by the deathly sound of a loud gunshot.Frantically running to their driveway, Myrlie and the kids found Medgar Evers shot in the back and lying in a pool of blood gasping for his last breath.Myrlie clung on to her husbands body as she and the children wept for this mans life.Almost thirty years later, the man charged with this murder would be tried again in a court of law, in front of a different jury of eight blacks and four whites.Justice was going to be served in the state of Mississippi no matter how long it was going to take. This murder case was tried in the racist state of Mississippi in the racist period of 1963.The judge was also a racist white man by the name of Moore and the jury consisted of twelve men. All white.Much evidence was presented to the court, such as the gun used to kill Medgar Evers consisting of fingerprints belonging to the convicted, Byron de la Beckwith.Byron and his vehicle were also spotted at the parking lot of Joes Drive-thru, a block away from the Evers household, on the night of the murder.On the other hand, two white men, Holly and Cresswell, claimed to have witnessed Byron de la Beckwith at a gas station in Greenwood, 90-95 miles away from the scene, on the same night.This case was tried twice ending both times in a hung jury, leaving Byron innocent and free of charge. Twenty-six years later, on October 1989, Myrlie Evers seeks to reopen the Medgar Evers case.A Mississippi lawyer named Bobby Delaughter, the son-in-law of Judge Moore, slowly took this task into his hands and dug up information and such on this forgotten trial.Upon making this decision, his wife leaves him, but he l

Research Paper Sample on Australia The System of Government
Research Paper Sample on Australia The System of Government As Australia prospers as a nation the debate to change from its current status of a constitutional monarchy to a Republic increasingly gains momentum. However, the 1993 referendum showed the majority of Australians donââ¬â¢t support this change and as John Howard an avowed monarchist colloquially argues ââ¬Å"If it itââ¬â¢s not broken, donââ¬â¢t fix itâ⬠. Australia should stop arguing this issue and move forward as we have done so well in the past. In 1901 Australiaââ¬â¢s separate colonies united under a constitutional monarchy embracing our independence while still respecting the cultural ties with Britain. The evolution of Australia from British colony to independent nation has seen many amendments to the constitution including The Australian Act 1986, Statute of Westminster and oath of citizenship. The Australian Republic Movement (ARM) established in 1993 by Labour Prime Minister Paul Keating argues Australia should accelerate towards a Republic despite the process is with far reaching ramifications and without substantial gains. Since the early 1900ââ¬â¢s the pro- republic stance after 102 years advocates Australians to adopt an unclarified alternative and as Kerry Jones states, ââ¬Å"accept an unstable system that is complex and deeply flawedâ⬠. (Article) Therefore, it can be seen that Australiaââ¬â¢s constitutional monarchy that has matured to be a unique and effectively Australiaââ¬â¢s system of govern ment be continued to serve us in the future as it has in the past. In 1998 a $35 million constitutional Convention comprising of 152 delegates agreed on a sole preposition (Appendix 1) being of minimal constitutional change in order for Australia to proclaim Republic. As a consequence of John Howardââ¬â¢s ultimatum various Republican models were not explored. In I999 a constitutional referendum costing $55 million, 54.87% of Australians voted against replacing the Queen and Governor General with a President who would be appointed by a two third majority of the members of the Commonwealth and, 60.60% of Australian voted against an insertion of a preamble into the constitution. (Appendix 2) The defeated referendum result contradicted the opinion shown in polls earlier (Appendix 1) that the majority of Australians supported a Republic. It seems in theory Australians want a Republic, albeit in practise active republicans have always been a minority. The path to a Republic debate now has little chance of being successful without John Howardââ¬â¢s support and when only 8 referendums out of 42 to change the constitution have succeeded. Australianââ¬â¢s are sceptical. Les Murray a Republican, has said Australians wonââ¬â¢t vote for a republic unless they trust it and ââ¬Ëthey sure canââ¬â¢t trust the one they are being offered at the moment (Australian 20 September 1993) Not only has the Republic debate divided Australia, it has divided republicanââ¬â¢s themselves. (Appendix 5) ââ¬Å" Put any two Republicans together and they will disagree on what a republic entailsâ⬠(The Defender Issue 1 May 1999 page 2) Considering, a clarified and vague republican model has been the sole proposition it is better to protect what Australia knows has already worked. To introduce an undefined Republican model Australians may possibly condemn future generations to live under an inferior system of government. A republican model must be analysed before being implemented and not after. Considering, this republican model is a blueprint it in Australiaââ¬â¢s best interests to stay a constitutional monarchy. The ARM aimed to make minimum constitutional changes necessary to achieve a viable Federal Republic of Australia. Therefore, itââ¬â¢s as if Australia need sacrifice nothing in terms of the integrity of our present political institutions and the idea that a Republic is just a change in tittle. At the same time the Republicans argue, ââ¬ËAustralia needs to become a republic to demonstrate its independence, identity, and maturity.ââ¬â¢(Mark Mc Kenna republic.org.au) Australia has by far demonstrated to have cut the umbilical cord from the motherland and formed a mature independent identity while still respecting out traditional means. ââ¬Å"Under our system of government Australia long ago achieved complete independence symbolised by the Queens title being changed, by her own consent and by Act of the Australian Parliament, to Queen of Australia.â⬠(norepublic.com.au/) Appropriate amendments to the constitution have reflected the shift in Australian society and kept up to date with the times. In 1994 the oath of allegiance was amended to remove reference to the Crown (Appendix 3) to reflect core values in Australia. The Australian Act 1986, condensed the Queens power in Australia and proclaimed that ââ¬Å"the United Kingdom parliament now has no legislative authority whatsoever in respect of Australiaâ⬠(www.alphalink.com.au) Furthermore, the role of the Governor General a rather ceremonial position has changed from being formally a Queensââ¬â¢s representative appointed by the British government, into an Australian appointed by the PM who takes advice from Australian Ministers. Australiaââ¬â¢s governor general, Guy Green from Tasmania was only recently nominated by the Prime Minister. By becoming a Republic would not be an affirmation of our nationhood as we already play an independent role. The fact Australia held the Olympic games, raises their own army and diplomatic corps, engages in their own foreign affairs, treaties, determines al one their future and makes decisions eg going to Vietnam War without Britain, proves Australianââ¬â¢s independence from Britain. The Commonwealth is part of our history and constitutional development that serves proudly as out own. The Republicans major argument that Australia is not independence does not exist. The Republicans have failed to consider the intricate ramifications of an Australian Republic and even what shape the new constitution should take. At the constitutional convention in 1999 no assessment of such developments were proposed and central answers are overlooked. While Republicans want to replace the Queen the enormous implication of doing so are not manufactured and new institutional foundations and restrictions of the new office established. By removing the Queen new offices must be devised and complicated mechanisms implemented. Becoming a Republic raises issues that are still not answered such as; what will become of Crown land, a resolution to the position of the states, who will be the new president, method of appointment, length of tenure, power restrictions and importantly how will be president be appointed. ââ¬Å" A president selected by the Prime Minister would lack democratic legitimacy; a president elected by the people would have more authority than a Prime mi nister elected by MPââ¬â¢sâ⬠. (Quote) This de position power inturn can cause struggles for power, feasible political deadlock and mean enormous alterations to the constitution. Additionally, the Australian states individually have their own monarchist constitution and in the event of become a Republic it is unclear if monarchies remain and, if not what is required to bring them into conformity with a republican Commonwealth. It can be seen that the Republican movement is far from an improvement from a constitutional monarchy. A major flaw is that the model ignores to even recognise reconciliation, an essential component of any future republic. ââ¬Å"To declare a republic that failed to embrace reconciliation as one of itââ¬â¢s founding principles would not be a republic at all- nor would it be a Republic would havingâ⬠(Mark Mc Kenna) Australia should vote No to Republic that does not answer Australiaââ¬â¢s needs and will be extremely costly financially, and emo tionally. If we became a Republic the Republican advisory Committee estimated in 1994 the election for a president would cost $45 million minimum each time. The constitutional monarchy should be accepted to incur no further financial costs to taxpayers on the Republican issue. The Federal Parliamentââ¬â¢s time without doubt could be better spent debating more relevant and crucial issues. In practise Australia is a Republic in every sense worth worrying about, the constitution derives from the people, the government is democratically elected and the PM answers to parliament. In an Advisory Committeeââ¬â¢s report stated Australia is a ââ¬Ëcrownedââ¬â¢ Republic. The Queen, Elizabeth II is a leading figurehead as her political responsibilities and power is very limited. In Australian she is evident on Australiaââ¬â¢s money and far from foreign as sheââ¬â¢s in the papers and television. There is a generation of Australianââ¬â¢s that take great pride in the constitution and respectably admire the Queen. (Appendix _) The Queens is an educated faithful monarch who republican admit is more appropriate for the job. ââ¬Å"quoteâ⬠. Economically a Governor General would cost far more than a Queens who only has her security paid for when in Australia. The Queens still has a place in our democratic society and to replace the Queens would create enormous upheaval with no advantage. It is the Governor- General, and not the Queen, who exercise the powers of the Head of State, so that becoming a republic means money, time lost on a constitutional re-write that will give us what we already have. ââ¬Å"If the republicans are right and nothing will really change, why bother? If, on the other hand, theyââ¬â¢re playing down the extent of flow-on changes, why take the riskââ¬â¢? (Quote) Republican base their argument on the need to being independent and have an Australian as head of state but when we already have both there is no reason to risk changing. The republican movement may be an inevitable event in Australiaââ¬â¢s with a welcoming future generation. It is important to maintain an open mind to different Republican models. It is not out of the question undertake radical amendments to their constitutions it must be remembered in the 1890ââ¬â¢s the dramatically changes turned out to be a successful constitution. It seems in theory Australians want a republic but not in practise, until terms offered are clarified and understood. There is a low level of public understanding on the matter and a number of hurdles to jump before Australia can even comp template implementing a Republican model. Itââ¬â¢s only when political division is ironed out and society gains the real Republican agenda a referendum would be of no success.

Is less student purchase text books from school book store. Why or why Essay
Is less student purchase text books from school book store. Why or why not - Essay Example While indicative of the changing trend in the overall consumer purchasing behavior, the findings reveal the more immediate threat that the on-campus bookstore is facing. In the changing circumstances, the management needs to re-align its core business of selling with technology. This paper and the research undertaken by the author are aimed at discovering the book-purchasing habits of the students, and also endeavors to find out the possible reasons for their reluctance to buy from the on-campus bookstore. The above objectives were sought to be achieved through a primary research, using a close-ended questionnaire on a sample of 50 students. A literature survey was also conducted to establish how the consumer behavior is being modified by e-commerce, and how other bookstores are coping with the change. The author has observed, personally and through his interactions with his colleagues, teachers and staff, that there has been a debilitating trend in the book-purchasing behavior of students buying books through on-campus bookstores. The requirements of college course-work have become more and more challenging, and a student is continuously facing the daunting challenge of coming up with exemplary references in his papers. Not only he needs access to a gamut of the prescribed books, he also needs to embellish his work with sources, not yet available through his local campus. Online Libraries and online book vendors provide a cheaper and faster alternative for the academic needs of the students. M-commerce and e-commerce are making forays into the academic life, making available to him an array of study material, books, and journals right at his doorstep. There has also been a revolution in the availability of free information online ââ¬â through search engines like Google and Yahoo, a student can get access to whatever data he needs while sitting at home. In addition to the changing economy (the IT boom, availability

ITunes price changes hurt some rankings Assignment
ITunes price changes hurt some rankings - Assignment Example The article points out that two days after Apple iTunes Music store raised its prices on some individuals tracks, the sales dipped and with that the rankings of the songs. The iTunes top 100 chart registered 40 songs at $1.29 and 60 songs at the normal $0.99 price point. After the price change, the $1.29 songs lost 5.3 places on the chart while the $0.99 songs gained an average 2.5 chart positions. These changes give a general idea of how incremental changes in revenue can be reached. Moving up and down the chart impacts the revenue greatly which in turn is impacted by price changes. These changes are solely chart position, but a general idea of incremental changes in revenue can be reached. By looking at the unit sales of the most recent Soundscan top track downloads chart, the different between chart positions can offer a view into how moving up and down the chart impacts revenue. An assumption here is that the iTunes Top 100 chart is representative of the Soundscan top track downl oads chart. Given its market dominance, this is a reasonable assumption. I chose this article because it gives a good idea of how small changes in price can turn around Sales. A significant notion raised by this article is the way in which how prices alter the rankings of songs in the music industry. The prices change the rankings and the rankings which in turn impact sales and revenue. This article relates to chapter nine of our text book in which key issues related to initiating and responding to price changes are discussed. Buyer reaction to price changes are a result of the value the customers see in the price change. (Glenn Peoples) Works Cited Glenn Peoples, Nashville. How iTunes Price Changes Hurt Some Rankings. 10 April 2009. 19 May 2011 . Article: 7 in 10 Americans say High gas prices hurt This article is related to a recent chapter that we covered from our text book. Customers donââ¬â¢t react to price changes in a very straight forward way. A price increase is expected to lower sales. This is because a brandââ¬â¢s price and its image are closely tied together. Price changes will alter consumer perception about a particular product and the way they want to consume it. Thus price is a very critical factor. I chose this article because it offers insight into how price changes in a mandatory commodity such as gas influences the common man. The survey was conducted by USA today in which they asked people if recent changes in prices of gasoline have impacted them financially. 7 in 10 Americans believed it did. More than half of them claimed that they have had to make changes to account for higher prices of gasoline. 21% of them felt the impact so heavily that they believed it jeopardized their standard of living. (Stauss) Stauss, Gary. 7 in 10 Americans say high gas prices hurt . 18 May 2011. 19 May 2011 . Article: Apple and Starbucks announce music partnership The article talks of the Apple and Starbucks music partnership. Under this partnership, cu stomers at Starbucks will be able to wirelessly browse, look around for music, buy and download music from the iTunes Wi-Fi Music Store at Starbucks on their iPod touch, iphone, Mac or PCs running iTunes in a participating location. They will also be available to avail the new ââ¬Å"Now Playingâ⬠service under which the name of the song playing in the Starbucks store at that particular moment will be shown. They will then be able to buy and download songs directly to their device. The partnership will benefit both Apple and Starbucks and is a classic example of horizontal marketing. I selected this article because I felt that having free access to the iTunes Wi-Fi Music store and the Now Playing service of Starbucks is a great ways to attract customers to both Starbucks and Apple iTunes. It will trigger greater revenues for both companies. This

Global System for Mobile Communications (GSM) Technology
Global System for Mobile Communications (GSM) Technology Investigation on the physical layer technologies employed in the GSM System Absyarie Syafiq Bin Shahrin Abstract Basically in this paper, we intend to give a rundown on GSM (Global System for Mobile Communications) specifically on the technologies employed at the physical layer in the GSM system. The GSM system is a very interesting topic as it revolutionized the way we communicate and it is still being used till this day. It is actually the 2nd Generation (2G) wireless system as it uses digital instead of analog and it also deploys Time Division Multiple Access (TDMA) that is implemented on multiple frequency subbands. Frequency Division Multiple Access (FDMA). GMSK modulation and demodulation technique will also be discussed together with how it works and what their advantages/disadvantages are. The problems with ISI (Intersymbol Interference) in GSM systems will also be addressed together with how to mitigate ISI using channel equalization. With that, we will also give a simple explanation on how speech coding is accomplished in GSM transceivers. Keywords: Gaussian Pulse, GMSK, ISI, channel equalizer, ISI equalizer, speech coding I. Introduction GSM is a standard developed by the ETSI (Europe Telecommunication Standards Institute) to describe the protocols of the 2nd Generation (2G) communication technology used by mobile networks and cell phones. It was first launched in Finland with a data speed of up to 64kbps. The GSM is given the term 2G because it is something completely new compared to the first generation (1G) with the usage of digital signal signals instead of analog. It was designed from scratch with no backward compatibility with the previous 1G technology. Using 124 channels per cell, it can accommodate up to 8 users by using a combination of TDMA and FDD scheme [1], though some of its channels are used for control signals. It also introduces the SIM (Subscriber identity module) card which allows for roaming calls. At first, it was only designed for operation in the 900 MHz band but later it was adapted for 1800Mhz. GSM is a very popular standard used today with over 90% market share, with availability in over 21 9 countries and territories worldwide. Originally the GSM was developed with the intention that it will replace the first generation analog networks by having digital, circuit-switched networks which are optimized for full-duplex voice telephony. However as time passes, the GSM system was further developed to include data communications by firstly having it on circuit-switched transport, and then changing it later to packet-switched transport via GPRS ( General Packet Radio Service) and EDGE ( Enhanced Data Rates for GSM Evolution) . In GSM, Gaussian pulse shaping is used and Gaussian Minimum Shift Keying (GMSK) as a modulation/demodulation technique with a modulation index of 0.5 [2]. This modulation method however gives rise to inter symbol interference. Inter Symbol Interference (ISI) in the GSM system are usually caused by two factors; Multipath propagation and Bandlimited channels. An ISI equalizer is used to solve this problem by implementing the Maximum Likelihood Sequence Estimation (MLSE) via vertibri algorithm. To make things easier to understand, Figure 1 is attached to relate how the GSM system can relate to the OSI (Open System Interconnection) model. We will however, focus more on the Physical Layer of the GSM system. Figure 1: How the GSM is realized in the famous OSI model [7]. Pulse Shaping In digital telecommunications systems, we strive to achieve broad spread spectrum with significant low-frequency content. This in return, requires a lowpass channel that has a bandwidth sufficient enough to accommodate the essential frequency content in the data stream. Gaussian function fits this requirement perfectly. The speciality of this waveshape is that, the pulses rise and small smoothly until it settles to a value [14]. This is a valuable asset as it gives a solution to problems such as precursors, overshoot and ringing in a pulse signal [14]. This problems cause uncertainty to the actual value so it is very troublesome. Besides that, it also addresses the two required needs of communication systems which are band-limited channels and reduced Inter-symbol interference (ISI) by applying a Gaussian filter symbol-by-symbol. It is nearly impossible to get the perfect sinc spectrum in the time domain as the bandwidth needs to be infinity. We can only have an approximation or near the same sinc spectrum. ISI can also still happen if control is not exercised over the pulse shaping. Figure 2: An impulse response of a Gaussian Filter [15] In GSM, we apply Gaussian filtering for Gaussian Filtering Minimum Shift keying (GMSK) a modulation technique. Basically it is similar as the Minimum Shift Keying (MSK) but the data stream must first go through pulse shaping via Gaussian filter before being applied to the modulator. MSK is already a good modulation scheme as it possess constant envelope and maintains phase continuity. GMSK allows for reduced sideband power which results in the reducing of out-of-band interference between the signal carriers in adjacent frequency channels. The GMSK technique has an advantage of being able to carry data while still maintaining an efficient usage of spectrum. The reduce power in the GMSK is very useful especially for mobile phones as lower battery consumption is needed for operation [16]. The drawback of GMSK is that, it requires more modulation memory in the system and causes ISI. We have two ways to generate GMSK modulation. The most basic way is to apply Gaussian filter on the input signal and then apply a frequency modulator with a modulation index of 0.5 [2] [16]. The problem with this method is that it must have an exact modulation index of 0.5. In the real world, this is impossible as component tolerance drift can vary[16]. Figure: Flow chart of GMSK modulation using a Gaussian filter and Voltage controlled oscillator The second method is more realistic and widely used. This GMSK method uses the Quadrature (I-Q) modulator. The operation starts by having the Gaussian filtered data separated into two parts, in-phase I and quadrature phase (Q). The I and Q components will then be mixed up to the frequency of the RF carrier to have a modulated RF signal. This kind of modulator can maintain 0.5 modulation index without having any modifications. The performance of this quadruple modulation depends on the accurate creation of I and Q components. For demodulation, this scheme can be used in reverse [16]. X ââ¬â mixer or multiplier LO ââ¬â Local oscillator Figure 3: Block diagram of I-Q modulator Inter symbol interference and channel equalization ISI in the GSM system is mainly caused by multipath propagation. Multipath propagation is a result when signals arrive at different times (delay) because it is does not travel in line of sight (LOS). In reality, connection will never be in LOS all the time so the signals will go through different paths by being reflected or refracted from different objects to reach the destination. When the signals travel through multiple paths, they will arrive at different times depending on the route they used. It is also possible for reflected signals to overlap with the subsequent signals [13]. This in addition, results in distortion to the received signals because all the signals have different delay. This situation happens either from mobile station to base station or vice versa. Since the delay spread is more than the symbol time, frequency selective fading occurs. Figure 4: An example of multipath propagation Figure 5: ISI as a result of multipath distortion [13] To combat the problem with multipath propagation, we use and ISI equalizer. This equalization technique is based on the MLSE which uses the Viterbi Algorithm [3] [10]. Figure below shows the block diagram of the ISI equalizer. Figure 6: Block diagram on how ISI equalizer is used in GSM environment When the base station or the mobile station transmits a TDMA burst, not all of is user data. Instead, 26 bits are allocated for the training sequence and they are known by their receivers (either mobile station or base station). Each of the known sequence bits unique for a certain transmitter is unique for a certain transmitter and this sequence bits is also repeated in every transmission burst. The figure below shows the normal burst structure in the GSM burst. Figure 7: GSM Normal Burst Structure A channel estimator is needed because to perform MLSE, we require information on the CIR (Channel Impulse Response). The channel estimator will estimate the CIR for each of the bursts by comparing the transmitted bits with the received signal to produce he(t) [10]. Channel estimation in GSM uses Linear MMSE (Minimum mean square error) [11]. Since the match filter is in time domain, r(t) will be convoluted with the signal obtained from the channel estimation, he(t) to create a model signal Y(t). The output model signal obtained can then be used to estimate the transmitted bits based on the bits received by performing MLSE. The last process uses Viterbi Algorithm hence the process, Viterbi equalisation [2] [9]. Speech coding in GSM transceivers Speech is originally analog in nature and GSM is a digital system. In order to use the speech information, we need to run to a series of process known as speech processing. Figure shows how the speech processing is done in a GSM system. In speech coding, the GSM system has used a variety of ways to fit in 3.1 kHz audio into between 6.5 and 13 kbit/s. The first two codecs used was called Half Rate (5.8 kbit/s) and Full rate (13 kbit/s) [4]. Both of this codecs use LPC (Linear Prediction Function) where voice signals need to be digitized, and secured using encryption over a narrow voice channel. As time passes, the GSM system was further developed to use the Enhanced Full Rate (EFR) codec which is a 12.2 kbit/s codec and it uses a full-rate channel. Figure 8: Flow-diagram on GSM speech processing [8] Full rate speech coder is actually part of the Regular Pulse Excitation ââ¬â Long Term Prediction (RPE-LTP) coders [4]. Firstly the speech encoder will take an input of 13 bit uniform PCM signal from either the audio part of the mobile station (MS) or the Public Switched Telephone Network (PSTN) side by using 8 bit/A-law to 13 bit uniform PCM conversion. The encoded speech is then delivered to the channel coding function which will then produce an encoded block having 456 bits with a gross bit rate of 22.8 kbps [4] [5]. The remaining 9.8 kbps is used for error protection purposes. The reverse action is performed for decoding. When encoding, 160 frames in 1 sample is encoded to a block of 260 bits with a sampling rate of 8000 samples/s, hence the bitrate of 13kbps [5]. On the decoding part, 260 bits of encoded blocks is mapped back to the 160 frames output reconstructed speech sample. EFR (Enhanced Full Rate) is a newer version of the speech codec which uses ACELP (Algebraic Code Excited Linear Prediction) algorithm. The motivation for this development is because of the mediocre / poor quality of the GSM-Full Rate codec. This codec is a step-up from the previous FR because it provides speech quality equivalent or close to wireline telephony which uses 32 kbps ADPCM (Adaptive Pulse Code Modulation) [6]. This codec can provide wireline quality in both error and error-free conditions [6]. EFR which is also a form of traffic channel is bi-directional and can transmit both speech and data [9]. Figure 9: shows how error correction is done at layer 1 of the GSM air interface Conclusion All in all, this paper has helped me to better understand the GSM system and how it works in the physical layer. GSM has many sources including but not limited to, books, journals, application notes, lecture notes, documentation as well as survey papers. After reading from various sources, I learned to read efficiently and think critically as the papers written are quite hard and requires a meticulous reading to thoroughly understand what is being presented. I acquired basic research and development (RD) skills and technical writing skills after almost a month of heavy reading and research. How the physical layer in the GSM system works is also understood. The acquired signal must first be shaped through a Gaussian filter in the GMSK modulator. The Quadruple modulator scheme is used as it does not require modifications to maintain 0.5 modulation index. ISI in the GSM are mostly caused by multipath propagations in which gives frequency selective fading. Frequency selective fading happ ens when the delay time is spread because symbols arrive at different times. To address the problems with ISI, we need to have an ISI equalizer. ISI equalizer consists of many components such as match filter and MLSE by Viterbi algorithm. I also learned that we have two speech coding options; full rate speech coder and EFR. All this components are essential when building a GSM system.
