Matter and Materials Physics Assignment Essay Matter and Materials Part 1 Here is a list of definitions of important terms, with the sources of information in brackets: Tensile Stress (1) Tensile stress is the tensional force acting on a solid per unit cross-sectional area. It is represented by the symbol ? and is measured in N m-2 or Pa. (They are the same thing). Formula: ? = F / A Strain (1) The tensile strain is calculated by dividing the extension produced in a solid (i.e. a wire) under tension, by its original length. It is represented by the symbol ? and has no units. (It is a length divided by a length). Formula: ? = e / l The Young Modulus (1) The Young Modulus is a means by which we can measure a materials relative resistance to tensional force. If a material obeys Hookes Law (as most of them do, at least to an extent) then the tensile stress is proportional to the tensile strain, and the ratio of stress to strain is a constant, which is characteristic of a material. This is called the Young Modulus, and it is calculated by dividing tensile stress by tensile strain. It is represented by the symbol E, and is measured in N m-2 or Pa, as we divide a measurement in Pa by one with no units. Formula: E = ? / ? , or E = F l / A e. Density (1) Density, a characteristic of a material, is defined as mass per unit volume, and is a measure of relative massiveness of a material. Density is represented by the symbol ? and is measured in kg m-3. Formula: ? = m / V Stiff (1) The stiffer a material is, the more difficult it is to be deformed (have its shape or size changed) by a force. Plastic (1) A material is said to be plastic if, when you deform it, it stays in the new shape after the force is released. Elastic (1) If a material is elastic, then it will return to its original shape after being deformed. This is the opposite of plastic. Brittle (1) A brittle material does not change shape at all when a deforming force is applied. It eventually breaks without warning, and the pieces can be fitted back together. Ductile (1) A material is ductile when it can be deformed by a large, steadily applied force. Most economic metals are ductile- they can be drawn out into wire, for example. Tensile Strength (2) The Tensile Strength, or Ultimate Tensile Strength (UTS) of a material, is the amount of tensile stress a material can take just before snapping. It is measured in N m-2 or Pa. Yield Stress (1) The Yield Stress is the amount of tensile stress required for a material to yield. Certain materials, for example mild steel, when under sufficient stress, begin to extend at a very fast rate without additional pressure being applied. This is caused by the materials internal structure losing its integrity. The crystal planes within the metal can slide past each other, and the material becomes completely plastic for a time, but then breaks if any more force is applied.

Information about a metal Aluminium is a very light metal, with a melting point of 660à ¯Ã‚ ¿Ã‚ ½C and a boiling point of 2467à ¯Ã‚ ¿Ã‚ ½C. It is highly electropositive and reactive, and it is this property that makes it extremely resistant to corrosion- on contact with air it rapidly forms a skin of aluminium oxide, which resists any further chemical corrosion. Aluminium is the most abundant metal in the Earths crust, but most of it is contained within complex silicate minerals, from which it is far too expensive to extract. The main source of Aluminium is Bauxite, which is an impure aluminium oxide ore. Part 2 I have been given data for the force and extension from stretching a wire, and the original length and diameter as constants. The formula for the Young Modulus is E = F l / A e , so I will have to manipulate the formula into a graph. If I made a graph of F against e, the gradient would be equal to F / e. Multiplying this by the l / A would give me the Young Modulus. Calculation for the Area A = ? d2 / 4 A = ? (1.0010-3)2 / 4 = 7.8510-7 m2 Therefore l / A = 3.00 / 7.8510-7 = 3.82106 m-1 Below is the spreadsheet data I downloaded. To the right is the graph I constructed from the data.

My impression of Commercial Radio in Asia Essay Example for Free

My impression of Commercial Radio in Asia Essay A very significant impression that commercial radio in Asia makes is the strength of commercial radio in the region through the years, especially in comparison with other multi-media platforms. Before the era of the internet, the tri-media through sociological aspects have directly or indirectly created a balance that made the relationship of the three media platforms evenhanded. There are advantages and disadvantages found in print, television as well as in radio, even when there are times that social factors alter the balance temporarily, like the television ad ban and newspaper ad limitations set in Indonesia before which favored commercial radio, income-wise (Anderson, 1984, p. 180). For radio, as well as for the rest of the other forms of media, they managed to thrive by making the most out of their advantage over the other forms. Radio’s advantage rests on the accessibility and mobility of information through use of radio as well as the presentation of more real-time information compared to television and print. This is one of the particular strengths commercial radios demonstrated in Asia, the reason why many of its patrons remained loyal to radio despite the improvement in television and print and the entry of the internet. Asia is one of the regions that serve as hotbeds of radio even when in many places radio patronage have dwindled because of the change in sociological factors affecting media use and impact. This can be attributed to the fact that most Asian countries are still comprised heavily by rural areas that have not fully embraced modern technology, relying on the more traditional means, particularly the cheap and accessible radio. In these rural areas, print media finds it difficult to thrive because of socio economic and political reasons, and television is mostly reserved in living rooms, for those who are fortunate to have one. Most people in the rural areas of third world or lower class countries in Asia can only manage a radio for their source of information and this advantage is being used to the hilt by commercial radio owners and operators. The demand created by social conditions are favoring commercial radio immensely even today, particularly in Asia, and for its part, commercial radio has not abandoned its responsibility to those who depend on it. Another significant impression made by commercial radio in Asia is the new role that it plays in modern day culture. While there are factors from the past that still affect or characterize commercial radio today like the traces of previous commercial radio cultures like dependency on commercial radio for new songs and top of the charts lists radio listeners from India and other Asian countries (Kasbekar, 2005, p. 134), radio and its role in modern day culture no doubt transformed and metamorphosed, proving that radio is indeed characterized by â€Å"timeliness (Applegate, 2004, p. 120)† as well as timelessness. Before, the design was one-way information channeling, radio anchors and disk jockeys provide information and entertainment which the listeners consume, and the focus, particularly of AM stations, are largely political. â€Å"A vital part of the cold war between Taiwan and China is radio broadcasting (Wood, 1999, p. 163). † Today’s radio (despite the handicap of absence of visuals) manages to incorporate interactivity in its scheme of things. DJs and anchors interact more with listeners and callers, making the relationship more personal. Because of the shift in age demographic, commercial radio is enjoyed by different age brackets and has involved itself more in lifestyle and culture. Besides news and music and radio programs, the content now include sports, gossip, entertainment, lifestyle, and a wide range of other interests, allowing radio to be appreciated in a new light. Commercial radio has also been an important proof of the change in lifestyle, both in rural and urban places in Asia. Political and social changes lead to change in culture and attitude, and how individuals continued supporting commercial radio is proof of this change. â€Å"The number of local youths listening (in Asia) listening to the radio primarily because it is a foreign-language station is testament to its attraction in this regard (Shoesmith, Rossiter, 2004, p. 57). † This shows that the strength of commercial radio and its success rests largely on its ability to adapt to new environment and culture.

Israel †Lebanon War and related problems faced by the American community Essay Example for Free

Israel – Lebanon War and related problems faced by the American community Essay Introduction At the time of cold war, democratic world was, virtually, confronted by only one threat, coming from communist regime of the Soviet Union. This foe, though being dangerous, was quite predictable and civilized to certain extent. After the cold war seized it seemed that world would finally find global peace and mutual consent. However, things turned different and such hopes vanished into a thin air. The world community faced new, formerly unwitnessed, threats related to religious, national, and ethnic intolerance. Commonly accepted, though ultimately mistaken, is the belief that the fighting against these threats must be narrowed down to the war against a particular enemy, world terrorism. Comparing the old and new world (time before and after the cold war) it must be noted that confrontation between democratic world and the Soviet Union was based on certain rules, preventing the world from the global conflict. Confrontation with a new enemy has no rules at all. It turns out that to settle a conflict of a new type is more difficult than it used to be, partially because of the reason that sometimes it is, practically, impossible to detect a real initiator of a conflict. All participators of a conflict are guilty. Besides, among the other significant reasons is the great number of conflicting parties and, as a consequence, there is a highly complicated interlacement of interests. To protect interests of one party without neglecting the interests of another one is almost an unattainable aim. The bright example of the conflict of new type is a currently continuing war between Israel and Lebanon. This war affects the events all over the world and American community in particular. Israel – Lebanon war raises an array of problems that need to be solved by the world leaders as soon as possible. Short Historical Background It is reported that â€Å"on 12 July 2006 Hezbollah initiated Operation Truthful Promise named for a â€Å"promise† by its leader Sheik Hassan Nasrallah to capture Israeli soldiers and swap them for the remaining three Lebanese held by Israel. The early morning raid into Israeli territory resulted in eight Israeli soldiers killed and two captured. Israel then responded with Operation Just Reward later renamed Operation Change of Direction. Israels retaliatory strike has thus far encompassed bombing raids by the Israeli Air Force (IAF), an air and Israeli Sea Corps naval blockade of Lebanon (especially southern Lebanon and Beirut), â€Å"a force of tanks and armored personnel carriers†, and some small raids into southern Lebanon by Israel Defense Forces (IDF) ground troops. Hezbollah has concurrently engaged in extensive rocket attacks on Israels northern cities, including Haifa. However, the Lebanese government has constantly disavowed Hezbollahs actions and refused to condone them, while urgently calling for international peacemakers to end the conflict. † (Wikipedia) This short passage gives a clear and overall picture of the background of current situation in Middle East. It must be noted that Hezbollah operations on Israeli soldiers capture was preceded by Israel occupation of the west bank of the Jordan River and Gaza Strip. This occupation was in its turn preceded by â€Å"Hamas raid into Israel and capture of an Israeli soldier† (CNN. com) This bundle of events can be untwined to infinity. Analysis of events and their projection at US Foreign Policy The world community acknowledges that Hezbollah is a terrorist organization which directs its actions against Israeli state. Respectively, no one denies Israel’s right to protect itself and its citizens as well as no one rejects Israel’s demand to disarm or destroy this organization. However, Hezbollah located its military camps on the territory of sovereign state of Lebanon, the government of which is, virtually, incapable to control the activity of this organization. Now the issue of Israel self-defense arises from a different perspective: is Israel authorized to conduct military actions against terrorist organization on the territory of a sovereign country? And if initially most countries justified Israel’s actions, civilian casualties made the world be divided basing on its reaction to the Middle East conflict. As it is stated in the article at CNN. com â€Å"leaders in Europe and the Middle East see the attacks against Lebanon as disproportionate† and this statement provokes a new question: at what exactly moment these attacks became â€Å"disproportionate† and Israel self-defence transformed into aggression? When ten civilians were killed or twenty? This question is not a simple one as it raises the global problem of the right to resort to weapon against certain country. It is directly related to the American community and to get into the root of the matter it would be useful to have recourse to the investigation of the question of the legality of the USA invasion into Iraq. Speaking about military invasion legality, as Crahan states, â€Å"†¦ the answer may seem obvious: the U. N. is the worlds premier political body, its Charter requires Security Council authorization for the use of force [†¦]†. (Crahan et al. , p. 135) No one can disagree with this statement. The situation in which the force can be applied is also obvious: there should be continuous failure to execute resolutions, carried by UN Security Council, or their systematic violation. In particular, what concerns Iraq, there was an array of resolutions carried, which Iraq refused to execute. But it is necessary to clarify was it solely Iraq’s fault? As Crahan further continues â€Å"†¦the world body had failed in all those years to attain the goals that the President was seeking, in large part because the Council was bitterly and chronically divided on the critical question of how — sometimes even on whether — to enforce its numerous resolutions on Iraq. † (Crahan et al., 135) Thus it follows that the Council, while carrying its resolutions, even if under the pressure from U. S. side, itself resists their execution. Here the EC countries and Russia are to be fully reproached. No country in the world would execute any resolutions in such circumstances. However, when it came to the point when acts of force were very likely, Iraq, nevertheless, began to execute U. N. Security Council resolutions. But this time the USA and allies decided to launch the invasion with complete neglect to international law . Such total neglect to the Council resolutions, even by its permanent members, caused the situation where UN Council turned into a fake organization, unable to solve global conflicts. Now it is time to return to the case with Israel-Lebanon war, which is more complicated. It should be noted that this war is, virtually, the war of radical Arabs against Israeli country where, unfortunately, peaceful civilians have to suffer. The UN Security Council has passed corresponding resolutions against both enemy parties – Hezbollah organization and Israel. It must be observed that UN Security Council also passed the resolution concerning Hezbollah in 2004 , however, two years passed and it still was not applied either. Failure to fulfill this requirement was a formal ground for Israel to attack the territory of Lebanon. Moreover, the Security Cabinet of Israel â€Å"agreed Israel will not give up its demand for Lebanon to implement U. N. resolution 1559, which calls for the disarmament of Hezbollah and any other militias, and the deployment of the Lebanese army in south Lebanon†. (www. gopusa. com) However, scrutinizing this war in the context of the Arabs’ war against Israel, one should notice, that Israel made it its principle to violate UN resolutions as related to its enemies. It is necessary to mention the resolutions, the ground of which is the principle of â€Å"land for peace† (See resolutions 242 (1967), 338 (1973), 1397 (2002) and 1515(2003) at Global Policy Forum, July 13 2006). Also it must be noted that Hezbollah movement is supported by Syria and Iran. Syria regards Israel as enemy country due to the Israel’s occupation of Golan Heights, territory of Syria. The cessation of occupation of these territories, according to the â€Å"land for peace† resolution, would stop Syria’s support of Hezbollah. Important in that confrontation is the position of the USA. One should mention Council resolution, vetoed by US, which was forwarded by Qatar as of July 13 2006. Some excerpts from this resolution are relevant here: â€Å"The Security Council, Reaffirming all its relevant resolutions, in particular, 242 (1967), 338 (1973), 1397 (2002) and 1515(2003),†¦ Condemning military assault being carried out by Israel, the occupying Power, in the Gaza Strip, which has caused the killing and injury of dozens of Palestinian civilians, and the destruction of Palestinian property and civilian infrastructure, notably Gaza’s main power station, and condemning also the detention of democratically elected Palestinian and other officials, Condemning also the firing of rockets from Gaza into. Israel and the abduction of an Israeli soldier by Palestinian armed groups from Gaza, and the recent abduction and killing of an Israeli civilian in the West Bank, †¦ Calls for the immediate and unconditional release of the abducted Israeli soldier;†¦ Calls upon the Palestinian Authority to take immediate and sustained action to bring an end to violence, including the firing of rockets on Israeli territory;†¦Ã¢â‚¬  (Global Policy Forum, July 13 2006) What exactly in this resolution was unacceptable for Bush’s administration that induced it to veto the given resolution? Was not it the fact that the resolution one more time reminded of systematic UN Council resolutions violation by Israel? Was not it a demonstration of double standards? The idea on this issue is clearly expressed in the article The Economist â€Å"Israel ignores the United Nations and has weapons of mass destruction. So why all the fuss about Iraq? Soon after invading Kuwait in 1990, Saddam Hussein realized that he had made a mistake. [†¦] But as the world debates the merits of another American-led war against Mr. Hussein, the idea has returned in a new form. Israel has violated countless UN resolutions and amassed weapons of mass destruction, say those who oppose this war. Why then is Iraq singled out for yet more punishment while the Israelis get off scot-free? † (www. economist. com, 2002). These question remains without answer. The analogy can be drawn between the case with Hezbollah and Israel and the behavior of a host as regards a thief. If a thief (Hezbollah) breaks into someone’s house (Israel) so what shall a host do? He should call police! (in case with Israel appeal to the UN Security Council). And what does the host do? He starts striking with his axe destroying everything on his way, including innocent neighbours. But as it turns out the host is himself on the wanted list for countless crimes (resolutions violation). What is then in this situation a host, victim or criminal? And who is to be protected by police (by the USA)? Exactly such inconsistency between the crime and punishment, elevation of one party and humiliation of another, provokes the Muslim world to hate the U. S. policy. Israel’s actions are treated by Arab countries as a challenge to the whole Muslim world. The USA and its citizens began to be looked at as Israel’s supporters who can disregard and manipulate international law leaning on their military and economic might. For a common American citizen this is a terrible situation. In any place of the world he or she becomes an object of hatred. US government’s attempt to protect its people in military manner (in Iraq) and ignoring Israel’s aggression created the situation when neither in Europe nor even at home the Americans can feel safe (9/11 events). In other words, military methods, unapproved by world community, in fact, helped to solve Iraq or Hezbollah problems but immediately generated many other problems. But will Israel attain its aim (peace and remove the threat) when civilians die? Most probably it will not, while killed Hezbollah militants will be replaced by others those, who formerly were peaceful civilians but began to hate Israel because of bombings and there will be the same old story again. The way out from this predicament is to defend not only the interests of own nation and citizens but stand upon the values common to all mankind. Thus Israel defends its citizens by bombing Lebanon but it does not care for dying civilians what leads to conflict escalation . Like Israel, other countries are not governed by human values too. Thus BBC reporting on the evacuation of civilians from Lebanon states: â€Å"A British warship has dropped off 180 UK citizens in Cyprus, and is returning to Beirut to pick up more people, A Norwegian ferry has taken hundreds of Norwegians, Swedes and Americans to Cyprus, while a US-chartered ship has left Beirut with US citizens† (BBC News). The immediate question arises: should not they take first women and children from the territory of conflict? Only when American community realizes that human values are more important than any other, national, religious, ethnic or racial interests, and politicians adhere to this principle, only then the attitude of the world towards the USA and its citizens will change. Another aspect, that American community is confronted with, is constantly increasing military expenses. One can extirpate radicalism and extremism by military means but there is also a chance first to find reasons that induce extremism and then try to eliminate these reasons. Thus Ahmad S. Mousalli in the article Islamist Perspectives of Regime Political Response: The Cases of Lebanon and Palestine claims that â€Å"†¦Israel, Egypt, Jordan, Syria, Lebanon and Palestine †¦ are plagued, in one way or another, with poverty, inflation, underemployment, and exploitation. Many Palestinians or Egyptians, for instance, may turn to Islamism because of the corruption of their political elites, exploitation of the nouveau riche, nepotism, favoritism and the like. † (1996, 53) In this view the part of expenses, spent on army, could have been directed to support and reorganize economy of the Middle East countries. One more thing that deserves American community’s attention is that while possessing the veto power in UN Security Council, the US government abuses its power. To prove it there is a table below which shows the frequency of the use of the veto in the Security Council by different countries during the last decade. Period China* France Britain US Russia Total 2006 1 1 2005. 2004 2 1 3 2003 2 2 2002 2 2 2001 2 2 2000 0 1999 1 1 1998 0 1997 1 2 3 1996 0 Table is taken from Global Policy Forum â€Å"Changing Patterns in the Use of the Veto in the Security Council† Retrieved from http://globalpolicy. igc. org/security/data/vetotab. htm The USA has a strong leading position in this table. This table is the confirmation of the following statement: â€Å"Many member states have expressed their criticism of the veto, arguing that the veto privilege is an anachronism responsible for much of the Security Councils undemocratic and ineffective procedures. Not surprisingly, those enjoying the power of the veto dont want to give it up. † (Global Policy Forum â€Å"The Power of the Veto†) So, the countries with veto power in Security Council should abandon it. Conclusion The situation around Israel and Lebanon is not an exceptional one; it reflects the general tension in the world. This war only confirms that the world policy desperately needs revision. It is necessary to establish new world order and the USA has to head this process. International relations must be established upon the principles different from those existing today, in particular, economically powerful country while taking any actions is obliged to take into account the interests of less developed countries. To settle conflicts it is necessary to resume the authority of United Nations and entitle it to make decisions as regards resorting to force in conflict settlement. The resolutions carried by this organization must be mandatory to all countries. This conclusion can be best supported by words uttered by the ex-president of the USA immediately after the cold war: â€Å"a new era-freer from the threat of terror, stronger in the pursuit of justice, and more secure in the quest for peace. An era in which the nations of the world, East and West, North and South, can prosper and live in harmony a world where the rule of law supplants the rule of the jungle where the strong respect the rights of the weak. † (Miller, Yetiv 2001, 56) Unfortunately, in 15 year period following that speech news line on BBC says: â€Å"The USA is going to accelerate military supplies of high-precision missiles to Israel†. (BBC News) This is exactly the way George Bush junior and Israel decided to realize Bush senior’s dream of the harmony in the world.

Native Americans- Minority Role Essay Example for Free

Native Americans- Minority Role Essay Power and Minority Group Position: The Case of Native Americans Majority/Minority group relations can be illustrated by studying the role of power and how it is distributed between groups. The majority, or group that wields the most power, directly affects the circumstances for the minority. In most cases power struggle leads to racial and ethnic inequality. This scenario describes the case of the Native Americans. Since the arrival of the Europeans in 1492 the Native American has systematically been dehumanized, decivilized and redefined into terms that typify a subordinate or minority role, restricted life opportunities persist today as a result (Farley, 2000). When European settlers arrived on American shores to settle a New World, around 7 million Native Americans had been settled in the wilderness north of present-day Mexico for some time. It is believed that the first Native Americans arrived during the last Ice Age, approximately 20,000 30,000 years ago, by crossing the Bering Strait from northeastern Siberia into Alaska. Over thousands of years, spiritual kin-based communities had survived by living off the land and bartering goods. Their diversity was reflected by their societies, which ranged from small, mobile bands of hunter-gatherers in the Great Basin to temple-mound builders in the Southeast (DiBacco, 1995). The encounter of early explorers with the people of the Americas would ultimately set in motion the destruction of long existing Native American life and culture. Engrained into the minds of the Europeans were prejudiced images and stereotypes of the Native Americans, which we struggle still today to eradicate. From the 1490s to the 1590s, Europeans pushed inward across America from both coasts. Encounters with these settlers attracted many Native Americans toward European goods, but their attitudes toward the newcomers themselves depended greatly on previous experiences (Farley, 2000). In most cases, the early explorers found the Native American peoples to be friendly and generous. Columbus was immediately struck by the peaceful, generous nature of the Taino. The Taino society was highly organized around a patriarchal hierarchy and distinguished by happiness and friendliness. Columbus frankly stated how surprised he had been to make friends with the Indians. He wrote, They are gentle and comely people. They are so naive and free with their possessions that no one who has not witnessed them would never believe it. When you ask for something they have, they never say no. To the contrary, they offer to share with anyone They willingly traded everything they owned (DiBacco, 1995) When the Europeans settlers started to arrive in the 16th- and 17th-centurys they too were met by Native Americans. The Natives regarded their white-complexioned visitors as something of a marvel, not only for their outlandish dress and beards and winged ships, but even more for their wonderful technology steel knives and swords, fire-belching arquebus and cannons, mirrors, hawkbells and earrings, copper and brass kettles, etc. (Jordan, 1991). Increased interaction led to the Indians becoming less self-sufficient and economically dependent on the whites. As the years went on, however, the natives began to realize that the Europeans had much more in mind than a few settlements. They began to realize that their entire way of life was under siege. By the time the truth occurred to them, however, it was probably already too late. Their bows and arrows were no match for the Europeans firearms, and their bodies could not defend against the foreign diseases (DiBacco, 1995). As the encroachment of settlers on Indian lands continued, so did the inevitable conflicts. To the Indians, the arriving Europeans seemed attuned to another world; they appeared oblivious to the rhythms and spirits of nature (Jordan, 1991). Nature to the Europeans was something of an obstacle, even an enemy, and these disrespectful attitudes were quite apparent to the Indians. The wilderness was also a commodity however: a forest was so many board feet of timber, a beaver colony so many pelts, a herd of buffalo so many hides (Jordan, 1991). The Europeans cultural arrogance and ethnocentrism, and their materialistic view of the land and its inhabitants were repulsive to the Indians. Europeans, overall, were regarded as something mechanical soulless creatures wielding diabolically ingenious tools and weapons to accomplish selfish ends (Jordan, 1991). Initial European impressions of the Native American population were formed by the descriptions of Columbus and other explorers. Although Columbus initially praised the Taino, crediting them with a very acute intelligence , he also provided an unfavorable view of Native Americans when he discussed the Carib Indians, who were said to be very fierce cannibals. This description set the stage for the long-enduring image of the hostile, savage Indian (Berkhofer, 1978). Another New World explorer, Amerigo Vespucci further established this imagery in his writings about the natives stating, The nations wage war upon one another without art or order. The elders by means of certain harangues of theirs bend the youths to their will and inflame them to wars in which they cruelly kill one another, and those whom they bring home captives from war they preserve, not to spare their lives, but that they may be slain for food; for they eat one another, the victors the vanquished, and among other kinds of meat human flesh is a common article of diet with them. Nay be the more assured of this fact because the father has already been seen to eat children and wife (Burkhofer, 1978). The recently developed printing press rapidly dispersed such images through both print and picture, and these representations became firmly etched in the minds of the Europeans (Bataille, 1980). Eventually, the Native Americans were considered subhuman and evil. The hope of civilizing the Indian was often expressed, but ultimately religion required the eventual submission of the Indians to white domination (Burkhofer, 1978) When colonies began to form in North America, the colonists wanted to create a world similar to the one they had left. The Indians were a major barrier to this progress and civilization. The colonists hoped the natives would embrace Christianity and become assimilated within the colonist society. When the Native Americans resisted, they, like the wilderness, became merely an obstacle in the colonists path. Because they would not conform to the European way of life, their destruction was inevitable. Because some justification was needed in order to wipe out the entire race, the stereotype of the bloodthirsty savage was solidified (Bataille, 1980). The Europeans were accustomed to owning land and claimed ownership of the new territory, justifying their actions with the fact that the Indians were nomads with no interest in owning any land. The conflicts led to many wars and various actions instituted by the Europeans in order to accomplish their objectives. The Indian tribes were at a great disadvantage during these wars because of their modest numbers, nomadic life, lack of advanced weapons, and unwillingness to cooperate, even in their own defense (Jordan, 1991). During the nineteenth century, the American Indians, by tradition a communal people, were forcibly separated from their native cultures and lands. By the mid-1840s most of the Native Americans east of the Mississippi River had been relocated to Indian Territory, as a result of President Andrew Jacksons Indian Removal Act of 1830. This act gave territory to Native Americans who agreed to reject their ancestral holdings. This act allowed the Indians to live on the declared territory indefinitely. Many refused to leave their homelands, however, engaging in battles destined to end in death and destruction. These Native Americans were subjected to numerous forms of violence, such as raping, scalping and lynching, among other acts (Zinn, 1980). The Europeans eventually stripped the Native Americans of most of their lands, and as the settlers pushed further west, the boundaries of the Indian Territory continued to shrink. As the wandering Indians encountered existing tribes and the designated Indian Territory became more crowded, conflicts over land and hunting rights ensued. The relocated Indians were often struck by famine, as buffalo and other game became scarce. The reduction of the overcrowded Indian reservations was continued as more white settlers arrived in America (Zinn, 1980). The building of the transcontinental railroad allowed for thousands of white setters to make their way across Indian Territory. Native Americans forced off their lands often starved on the poor land or died of diseases brought with the settlers from Europe. Indians were often pressured to sign treaties giving up land and agreeing to live on reservations. In return, the government vowed to provide the Indians with services and supplies (Todd, 1986). The white men did not uphold this promise, however. Most of the Native Americans were nomadic and nonagricultural, and all depended for survival on hunting the buffalo (Jordan, 1991). The settlers realized the usefulness of the buffalo hides and killed an estimated three million buffalo each year over a three-year period. The devastation of the buffalo was also devastating to the Indians (Jordan, 1991). Tensions were increased as Indians traveled outside reservation lines to hunt buffalo for survival. When government attempts at concentrating the Native Americans in reservations proved ineffective, many battles ensued between Indians and Americans. Because their designated land was insufficient, the Indians were forced to revolt in order to survive (Todd, 1986). Terribly disadvantaged, however, the Native Americans were not able to defend themselves against the settlers. Most American Indians saw themselves as citizens of sovereign Indian nations. In fact, during the first half of the 1800s, the U. S. government treated Indians who lived in tribes as members of separate nations. The federal government even negotiated formal treaties with them. All that changed in the latter half of the 1800s. The U. S.government began to look at Indians as wards or dependents instead of citizens of their own sovereign nations or citizens of the United States. In 1870, the Senate declared that the Fourteenth Amendment, which granted citizenship to African Americans, did not apply to American Indians who lived in tribes. In 1871, Congress stated that hereafter no Indian nation or tribe within the territory of the United States shall be recognized as an independent nation (DiBacco, 1995). In 1887, congress passed the Dawes Act, dividing both reservations and families. Indian families who agreed to live separate and apart from any tribe were given their own land to cultivate. After 25 years, the family would be granted both land and U. S. citizenship. This U. S. policy stressed Indian assimilation of the habits of civilized life through citizenship, education, and individual land ownership (DiBacco, 1995). Traditionally, Native Americans owned land through tribes and communities, as opposed to individually. The effort to individualize Indians and force them to forgo their tribal and traditional ways caused strife among tribal communities and provoked a growing Indian opposition (Zinn, 1980). Once again, however, the Indians suffered because the quality of their land was very poor, they were untrained at farming, and they lacked proper tools. Additionally, disease and malnutrition increased as common causes of death. Between 1887 and 1934, American Indian nations lost more than sixty percent of their land to the American federal government (Jordan, 1991). The end of the 19th century marked the end of the Indian Wars with an unprovoked massacre in 1890 during which Indian warriors, women, and children were slaughtered by U. S. cavalry at Wounded Knee (Jordan, 1991). In the end approximately 200 Native American men, women, and children had been killed (DiBacco, 1995). In the early twentieth century Indians continued to be the target of civilized assimilation efforts. In accordance with these efforts, the government funded Native American churches and schools. Education has been regarded as a primary tool in the cultural genocide, or assimilation, of Native Americans throughout history. Its overall effect severely diluted Native American culture with Christian European values and beliefs, but taught no Native American history (Keohane, 2003). The Carlisle Indian Industrial School in Pennsylvania, the Haskell Institute in Kansas, and the Chilocco Indian School in Oklahoma all sought to eradicate Indian languages and lifestyles. Native Americans from various areas were forced to send their children to such schools. Most were boarding schools where students would have no contact with their tribal homeland. Students were forced to adapt themselves to the culture of the colonists under a militarized system that enforced the use of the English language, English names, and Christian religion, while dismissing Native American cultures as uncivilized. Many of the students were even kept from their families during breaks as they were sent off to work under white families, still furthering their cultural immersion and strengthening the American economy. Kill the Indian and save the man was the Carlisle Schools motto (Keohane, 2003). During the first few decades of the 20th century, the gap between Indians and whites widened as Native Americans continued to find the thinking of white Americans illogical, and Federal officials continued to outlaw Indian religious practices. As assimilation efforts began to succeed, American Indians were reduced in the public eye to the status of ancient relics. For example, most citizens were unaware that ten thousand Indian men were serving in World War I or that educated Indians were becoming teachers, farmers, and ministers (Zinn, 1980). Many of the stereotypes of Native Americans originally created in Columbus time have carried over to contemporary society. This only solidified white attitudes about manifest destiny and the role of the Indian in North America. The bloodthirsty savage had become a staple of the popular dime novel and Wild West shows (Bataille,1980). By the time of World War I, the image of the ignorant, savage Native American was firmly established in popular film, which was greatly profitable though historically inaccurate. The generic Indian was portrayed in fringed clothing, communicating through grunts and simple language (Bataille, 1980). Even today, many people overgeneralize about Native Americans, seeing them as one people even though the tribes have always differed in many ways. In 1924, Native Americans were finally given some recognition as a federal law pushed U. S.citizenship upon the remaining Indian population, BE IT ENACTED , THAT ALL NON-CITIZEN INDIANS BORN WITHIN THE TERRITORIAL LIMITS OF THE UNITED STATES BE AND THEY ARE HEREBY, DECLARED TO BE CITIZENS OF THE UNITED STATES: PROVIDED, THAT THE GRANTING OF SUCH CITIZENSHIP SHALL NOT IN ANY MANNER IMPAIR OR OTHERWISE AFFECT THE RIGHT OF ANY INDIAN TO TRIBAL OR OTHER PROPERTY. THE INDIAN CITIZENSHIP ACT, APPROVED JUNE 2, 1924 Despite their newly gained citizenship, Native Americans were blocked from voting for the next twenty years in Arizona, Utah, and New Mexico. As a result, The Indian Rights Association and The American Indian Defense Association were formed to protect Indian rights, but the two organizations had limited power or impact (DiBacco, 1995). The plight of American Indians attracted little attention until 1928, when a shocking study, the Meriam Report, exposed the frequency of Indian poverty and the failure of government to fulfill allotted promises. The result of this new interest in reform was called the Indian New Deal, a new law that would restructure tribal governments and the administration of federal policies. The bill became the Indian Reorganization Act of 1934. It introduced federal programs to support Indian agriculture, vocational education, and economic development. It included a provision that allowed reservation communities to set up tribal governments patterned after local units of the American government. Despite criticisms of the law being too paternalistic and undermining tribal traditions, the authority of Indian communities actually did expand during this time. The new Indian governments began to assert their rights in order to reverse the loss of tribal sovereignty (Jordan, 1991). Even though American Indians sent twenty-five thousand men and women to World War II, ten thousand to the Korean conflict, and forty-three thousand to Vietnam, their efforts did little to erase negative images of Indians (Zinn, 1980). Such images have also persisted in federal policy. Following World War II the Bureau of Indian Affairs instituted a program to terminate the federal governments trust relations with many tribes. In 1953 government officials passed a bill reducing federal expenditures and shrinking the federal bureaucracy by getting out of the Indian business and setting Indians free from federal support and protection. Poverty and homelessness quickly produced frustration and anger, and these, in turn, produced additional problems: alcoholism, joblessness, and poverty (Zinn, 1980). In the late 1960s, the Civil Rights Movement kicked off a wave of political activism by Native Americans, successfully changing negative policies and views. A new voice began to be heard in 1961 when the American Indian Chicago Conference gathered to present an Indian agenda for the new Kennedy administration. As American Indian youth became more involved in national Indian issues, the National Indian Youth Council formed (DiBacco, 1995). Additional examples of this new activism and militancy would include the founding of the American Indian Movement in 1968, the occupation of Alcatraz Island in 1969, the Trail of Broken Treaties march of 1972, and the armed occupation of Wounded Knee, South Dakota, in 1973 (Farley, 2000). These and other actions produced a national and highly visible call for Native American self-determination. This new campaign also emphasized individual tribal culture and practices. Pro-Indian legislation emerged during the 1970s as a result of activism and self-determination. The Indian Self-Determination and Educational Assistance Act, was passed in 1975 and stipulated that tribes could enter into contracts with the Indian Bureau to administer their own programs, from education to health care to housing. Other new laws included a settlement of land claims in Maine in 1978 and two pieces of landmark legislation passed the same year. The Indian Child Welfare Act established a role for tribes in the adoption of Indian children and the American Indian Religious Freedom Act declared constitutional support for Native American religious freedom (DiBacco, 1995). Despite growing efforts at self-determination, exploitation still plagues the Native Americans. Recent water and energy needs have led to government and industrial encroachment on Native American Land. Native Americans have even seen their reservations recommended as toxic-waste dumping grounds in exchange for much needed money. Discrimination still continues, especially in cities near the reservations. Tribal governments have enormous responsibilities that include the protection of hunting and fishing rights, water rights, religious traditions, and cultural heritage. At the same time, they struggle to develop successful gaming operations, profitable industrial factories, and effective educational and social-welfare programs. The systematic disorganization and dehumanization of their societies have restricted life opportunities. Poor education, low income, bad housing, poor health, alchoholism, and suicides are serious problems facing Native Americans today. They suffer the highest rates of poverty and unemployment among racial minority groups in the United States. Conditions are worse on Native American reservations, where an estimated 1/3 of them still live. According to goventment statistics on income, Native Americans are the poorest of the poor. (Farley, 2000) Today, many people in the United States ignore or are unaware of the problems Native Americans face. Many of those who are aware often stereotype them as backward, drunk, or unmotivated. Relations between Indians and non-Indians in the United States have been marked by an unfortunate series of blunders caused by prejudice and negative stereotypes. Even still, todays 2. 1 million Native Americans have proved their resilience by surviving oppression in a world dominated by other races and cultures. Unlike other minorities who have fought for equal rights in American society, Native Americans have fought to retain their land and cultures and have avoided assimilation, at a hefty cost.

Causes of Whooping Cough

Causes of Whooping Cough Abstract Introduction The genus Bordetella contains species of bacteria which are related serologically each displaying similar characteristics such as morphology, size and staining reactions (Website 1). The Bordetella genus is responsible for respiratory infections that are common in both people and animals (journal 1); Bordetella pertussis was first isolated in pure culture in 1906 and was long considered the sole causing factor of whooping cough. However, further studies revealed that mild forms of whooping cough could be caused by Bordetella parapertussis and on occasions Bordetella bronchiseptica (website 1). Whooping cough is a highly contagious respiratory illness that affects humans caused by the gram negative bacterial pathogen Bordetella pertussis. This particular pathogen is a strict human pathogen with no evidence of an impact on animals or the environment (journal 1). The disease can be characterised by bronchopneumonia, paroxysmal coughing and the distinctive ‘whooping’ intake of air. Pertussis is more prevelant in developing countries where essential medical care is often not available and disease (journal 2) Species Associated with Bordetella Bacteria that belong to the genus Bordetella are of importance to both paediatric and veterinary medicine due to their ability to colonise and multiply on the ciliated epithelial cells of the respiratory tract (journal 4) Nine species have been identified within the Bordetella genus to date, only three additional members, B. bronchiseptica, B. parapertussis and b. homlessi (journal 3). B. pertussis and B. parapertussis are extremely closely related according to their genomes; B. bronchiseptica, which by DNA-DNA and DNA-rRNA hybridisation are also closely related to the two previous species. A more recent addition to the genus includes B. avium (formerly known as Alceligenes faecalis) (website 1) which is described as a bird pathogen causes turkey coryza and other respiratory infections in fowl (journal 2). Another late addition includes B. hinzii (formerly known as A. faecalis type II), which can lead to respiratory disease in poultry and is very rarely found in humans (website 1). B. trematum has recently been proposed for a novel species isolated from human wounds and ear infections; although none of the new species identified were associated with respiratory infections, they are phylogenetically si milar to other members of the genus (journal 2). Transmission Infection typically begins with the bacterium entering the airways of the host via airborne droplets derived from the cough of an infected individual. The pathogen proceeds down the respiratory tract and adhering to ciliated epithelial cells of the trachea and nasopharnyx in the host. Once attachment has occurred, the pathogen proceeds to replicate and colonise any adjacent areas. As part of Bordetella’s extensive range of virulence factors, it secretes toxins that damage the epithelial cells, which results in the loss of ciliated cells; this process induces the characteristic coughing (journal 2). Virulence Factors The main objective of any pathogenic bacterium is to colonise and replicate by exploiting its environment to the fullest extent. This can be achieved by the bacterium controlling and producing specific factors that enable it to infect the host (journal 2). Many of the virulence factors characterised in the bordetellae are common across the three species (B. pertussis, B parapertussis and B. bronchiseptica). These include adhesions such as filamentous hemagglutinin (FHA), pertactin tracheal colonisation factor and fimbriae, and toxins including adenylate cyclasehemolysin, dermonecrotic and tracheal cytotoxin. Other virulence factors are expressed by just one of the species, such as the pertussis toxin and serum resistant protein secreted by B. pertussis or a type III secretion system expressed by the species B. bronchiseptica (Journal 5) Bvg Regulation The majority of virulence factors displaced by this genus are controlled by BvgAS regulatory locus, a two-component regulatory system. BvgA is a 23 kDa (journal 9) DNA binding response regulator (journal 8). BvgS is a 135 kDa (journal 9) transmembrane sensor protein kinase (journal 8). This system assists the transition of B. pertussis between its virulent phase of Bvg+ and its Bvg phase which is avirulent (JOURNAL 10). For both B. bronchiseptica and B. pertussis, in order for sufficient respiratory tract colonisation the Bvg+ phase is necessary (journal 8), this phase can be demonstrated when bacteria is grown on a rich media at 37Â °C (journal 11) BvgAS undergoes a series of phosphorelay signal transduction events in response to an environmental stimulus that leads to differential transcriptions of target genes. This regulatory system has a distinct intermediate phase, Bvg1 that can be achieved with the growth of bacteria in that conditions are between Bvg+ and Bvg phases (journal 11). BvgS undergoes autophosphorylation when there is an absence of modulators, after several steps the phosphate group is transferred to the amino terminal domain of the second component. The phosphorylation activates BvgA and binds to promoter regions located on B.pertussis virulence activated genes (Journal 12). Filamentous Haemagglutinin Many virulence factors of Bordetella pertussis are well characterised and any mutations in these factors causes significant reduction or complete loss of virulence. The bacteria adhere to ciliated cells of the epithelium in the upper section of the respiratory tract. The filamentous haemagglutinin (FHA) is the major adhesion present across B. pertussis, B. parapertussis and B. bronchiseptica (journal 6). This particular virulence factor is crucial in order for B. pertussis to attach the pathogen to the host cell. FHA is a 220-kDA surface associated protein that is secreted to the extracellular environment to assist the adherence to ciliated epithelial cells, therefore initiating the pathogenic cycle (Journal 2). However, in recent studies using the closely related species Bordetella bronchiseptica it has shown that other adhesions are just as important in initiating an infection; any deletion of any of the four adhesions (FHA, Pertactin, fimbriae, Brk A) results in the decreased abil ity of B. bronchiseptica to bind to host cells (Book 1) Pertactin Pertactin can also be known as aliases p.69 and OMP 68 due to its electrophoretic mobility in SDS-Page, pertactin is a 60-kDa outer membrane protein which assists bacterial adherence. Similar molecules are produced by other members of the same genus; B. parapertussis produces p.70 and p.68 in B. bronchiseptica (Journal 2). In a comparison of the prn gene sequences of B. bronchiseptica, B. pertussis and B. parapertussis, the precursors were found to be homologous (journal 6). The mechanism in which pertactin promotes the adherence to the ciliated epithelial cells is unknown and no receptor has been found, It has been demonstrated by a number of groups that pertactin can be described as an immunoprotective antigen (Journal 2). Adenylate cyclase toxin/haemolysin Adenylate cyclase toxin, a 177 kDa polypeptide (book 1) is a highly toxic potent repeats in toxin (RTX) family and is a substrate of T1SS. This particular toxin consists of two functional molecules; adenylate cyclase domain which binds calmodulin and catalyses unregulated conversion of ATP to cAMP, and an RTX haemolytic domain which is responsible for the binding to target cells and translocating adenylate domain into the cytosol (journal 7). Evidence suggests that the increasing levels of cAMP produced can lead to a decrease in phagocytosis as well as inhibition of chemotaxis; this therefore affects a major part of the innate immune response book 1). ACT has the potential to play a role in adhesion by modifying a carbohydrate binding domain of FHA leading to an increased ability to bind to host cells. However, the main function of ACT appears to be its ability to inhibit the function of neutrophils (book 1). Pertussis Toxin (PT) – Type IV Secretion Pertussis toxin is a member of the AB5 toxin family, indicating it consists of five different subunits (book 2), with two copies of the subunit 2 together with single copies of S 2, 3 and 5 forming a pentameric ring. This mediates host cell receptor binding and the translocation of the S 1 subunit (ADP ribosyltransferase) (BOOK 4), it is considered the most complex bacterial toxin. Pertussis toxin is essential for bacterial virulence; it interferes with the mechanism used by host cells to remain in communication with the rest of the host’s body. Other affects include weight loss, elevated igE production, and increased sensitivity to histamine, serotonin and cold. While the pertussis toxin alters the behaviour of both human and animal cells, its ability to inhibit activation of the immune system in response to infection best explains its role in human whooping cough (book 2). A full understanding of Type IV secretion is yet to be achieved; however, it does provide a good example of the ability of bacteria to adapt groups of proteins to its new needs (book 4). Epidemiology In terms of epidemiological quantities, there are two fundamental aspects: the transmission rate and the length of the infectious period; these values determine the basic reproductive rate R0 (journal 13). The mucous membranes of the human respiratory tract are the natural habitat for Bordetella bacteria, although B. pertussis can survive outside the body for up to a few days and can be transmitted via contaminated items. Majority of infectors occur through direct contact with an infected individual (website 1). Prior to the 20th century was considered a terrible childhood disease, in 2008 it still occurs for approximately 195,000 deaths worldwide. Of these fatal cases 95% occurred in developing countries. Outbreaks have been found to be linked with incomplete or reduced immunisation of individuals. The vaccine formerly used was known as DTP and included antibodies diphtheria toxin (D), tetanus toxin (T) and pertussis (P); however, this vaccine has been replaced with a safer DTaP vaccine, reducing the side effects (website 2). Discussion Although many advances have been made, much remains to be discovered as to how the adhesions and toxins produced by the Bordetella species establish and maintain infection and development of disease.in host cell organisms. http://www.ncbi.nlm.nih.gov/books/NBK7813/ WEBSITE 1 http://www.who.int/immunization/topics/pertussis/en/index.html WEBSITE 2 http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1082800/ JOURNAL 1 JOURNAL 2 http://cmr.asm.org/content/18/2/326.full.pdf+html JOURNAL 3 JOURNAL 4 JOURNAL 5 http://ac.els-cdn.com.ezproxy.tees.ac.uk/S1438422104700168/1-s2.0-S1438422104700168-main.pdf?_tid=39b13536-78ce-11e3-a0ea-00000aab0f6bacdnat=1389231467_08ec4f32bf03d5b1bbcd2962a3d8df69 JOURNAL 6 http://ac.els-cdn.com.ezproxy.tees.ac.uk/S1369527409000022/1-s2.0-S1369527409000022-main.pdf?_tid=5086535e-78ce-11e3-a61d-00000aacb35eacdnat=1389231506_264d1d5985a0ebc34a51cd5e2841829b JOURNAL 7 http://jb.asm.org/content/189/10/3695.long JOURNAL 8 http://www.ncbi.nlm.nih.gov/pmc/articles/PMC108527/pdf/ii004367.pdf JOURNAL 9 http://www.ncbi.nlm.nih.gov/pmc/articles/PMC98121/pdf/ii001983.pdf JOURNAL 10 http://jb.asm.org/content/186/17/5692.full.pdf JOURNAL 11 http://ac.els-cdn.com/S1369527400001697/1-s2.0-S1369527400001697-main.pdf?_tid=51d25790-79a9-11e3-86be-00000aab0f02acdnat=1389325568_31e8be38dfd04481d06fa83d877cb8dd JOURNAL 12 http://ac.els-cdn.com/S0966842X05001654/1-s2.0-S0966842X05001654-main.pdf?_tid=4baef94c-79ac-11e3-a8e6-00000aacb361acdnat=1389326846_4eecbd9c825cd7b16b288d3acc79fd7e JOURNAL 13 http://books.google.co.uk/books?id=axeJ8Q9eJ3kCprintsec=frontcoverdq=bordetellahl=ensa=Xei=PlHNUqfFJMSt7Qa_-YCQCAredir_esc=y#v=onepageq=bordetellaf=false BOOK 1 http://books.google.co.uk/books?id=sTsC65kCJbUCpg=PA648dq=bordetellahl=ensa=Xei=PlHNUqfFJMSt7Qa_-YCQCAredir_esc=y#v=onepageq=bordetellaf=false BOOK 2 http://books.google.co.uk/books?id=FwGmyh2OUToCpg=PT575dq=bordetellahl=ensa=Xei=PlHNUqfFJMSt7Qa_-YCQCAredir_esc=y#v=onepageq=bordetellaf=false BOOK 3 BOOK 4 BACTERIAL MECHANISMS

A Plan To Sell Products

A Plan To Sell Products Merchandising, advertising, promotion, a plan to sell products, sales to the meet needs of customers, media planning are all well to be known as marketing. While these activities may be regarded as part of marketing, none of them is marketing itself. It is remarkable that there are two conditions that must be met before marketing is possible. Firstly, there must be a person or company that desires to sell a product or a service. Secondly, there is a need for potential buyers of the product or service. No matter which comes first, but both must exist. If both factors exist, marketing is the process or series of activities that the prospective purchaser of the product or service with the product or service. If there is a no problem in selling your product or service for profit, the marketing has been a success. If the problem is not to make profits, the marketing has failed. It is important to recognize, then that marketing is the sum of all activities related to bringing buyer and seller profitably together. 1.2 Introduction to Mauritius Mauritius was first explored by the Portuguese in the 16th century and subsequently settled by the Dutch who named it in honor of Prince Maurits van NASSAU in the 17th century. Uninhabited until the 17th century, the island was ruled first by the Dutch and then the French after the Dutch had abandoned it. The British took control during the Napoleonic Wars and Mauritius became independent from the UK in 1968. Mauritius is a parliamentary republic and is member of the Southern African Development Community, the Common Market for Eastern and Southern Africa the African Union and the Commonwealth of Nations. The main languages spoken in Mauritius are Mauritian Creole, French and English. English is the only official language but the lingua franca is Creole and the newspapers and television programs are usually in French. Ethnically, the majority of the population is Indian and there are also many people of African descent on the island and there are also European and Chinese minorities. It is the only African nation where the largest religion is Hinduism although Christianity and Islam also have significant populations. The dodo has been extinct since the mid-to-late 17th century 1.3 Introduction to Maradiva Maradiva Villas Resort Spa, Mauritius, (member of Leading Small Hotels of the World) is an exclusive haven of luxury spread over 27 scenic acres with 750 m of pristine beach.

These factors include: 2.1.1 Consumers The maximum numbers of consumers staying in the hotel are from France, then Europe, USA, Middle East, India and other countries. All the cliental from these places are of niche class. There are different types of clientele like corporate, Leisure, Business domestic clientele. Maradiva basically caters types of clientele they are: Corporate clients: since the hotel is well connected it has a huge corporate client Leisure Clients: since Maradiva is marketed as a leisure property it caters to many clients from around the global. Domestic clients: since the hotel is seasonal it offers a special rate of 14,000 MAU throughout the year for Mauritian guests. In this way it caters to the niche segment of the domestic clients (Source: From the hotel monthly Occupancy report) 2.1.2 Suppliers It is directly linked to the companys overall customer value delivery system. The suppliers provide resources to Maradiva to produce these services. If it faces any problems from suppliers it will directly affect the marketing strategies of the hotel. The local travels agents that Maradiva deals with are:- Mauritours The White Sand Tours Summer Times Elite Voyage Connections Expression holidays 2.1.3 Competitors Maradiva provides different strategies packages to generate customer value satisfaction. These strategies help them to compete with their competitors. The hotel by using these strategies must gain strategic advantage by positing their offerings strongly against competitors offerings.

(Source: http://www.state.gov/r/pa/ei/bgn/2833.htm) 2.2.3 Social The forebears of the various ethnic groups composing Mauritian society arrived as settlers, slaves, indentured laborers, and immigrants. Ethnicity, religion, and language have been important factors in shaping the way Mauritians relate to each other in the social spheres.

Mauritius is an outlier in the African scene in terms of its trade, industrial and macroeconomic regime. From the 1970s, Mauritius followed a mixed trade policy of import substitution coupled with incentives for exports through the Export Processing Zone. There have been three phases of adjustment since the mid-1980s, each with a different pace and coverage. Industries also plays an important role in an economy, the main industries in Mauritius are textiles, chemicals, food processing, tourism, metal products, non-electrical machinery and transport equipment. The food processing industry in Mauritius is largely composed of sugar milling. The Sugar cane industry arrived in Mauritius in the year of 1639. There are so many sugar-cane fields in Mauritius. There is also now organic sugar production on the island. Textiles industries have been one of the major industries in Mauritius for past 30 years. The Chinese population is mainly responsible for the development of textile on the island.

Only all a la carte menu provided on the island. Offering a novel sort of idea to the customers An all villa concept Basic category of the villa starts from 163 m ², and is the largest square footage accommodation per room in Mauritius. Each Villa has its own private plunge pool. The Only resort with Ayurvedic Spa in Mauritius which is a big competitor for Shanti Ananda hotel Mauritius, who are world famous for their spas. Cilantro, one of its restaurants has a live teppanyaki Japanese Cuisine which is very famous all over Mauritius. Weakness Due to the removal of brand Taj, the product Maradiva is unknown to the market, and has to create its new position in the market. Proximity from the airport isnt that good; it takes more than an hour from the airport. The resort does not have a mix of rooms and villas, due to which it faces severe business losses in the slack season. Lack of qualified and trained personnel is a very big problem in Mauritius due to the reason that most of the staff members are employed just after the schooling. Location- the resort is on the west coast, whereas most of the hotels, water sports activities, places to visit are on the other side of the island. The hotel only carters to the niche customers. Opportunity The resort should target more guests from the Middle East. They should try and target the tourist from Russia, China and Switzerland. The growing interest of tourist looking for private holidays. Threat Upcoming five star hotels. Duplication of concept with minor changes by new upcoming hotels. Being on seashore it always has a danger of the high tide in the sea. Segmentation Market segmentation is the identification of portions of the market that are different from one another. Segmentation allows the firm to better satisfy the needs of its potential customers. Customers within any market rarely have similar needs and expectations. As the country of Mauritius had been under the rule of British French people the place still holds a lot of common ideologies thus making it a hit destination amongst the British and French Nationals. Based on this fact the resort segmented various markets of the world into key markets (UK, France, Germany, and Switzerland) and developing markets (India, Russia, South Africa, Australia). As Mauritius has been known as a Honeymooners Paradise so the hotel based in this fact has targeted young and affluent individuals who would like to have their wedding done or a honeymoon. Not only the young but the place is a hit even with the elderly people Targeting Targeting or Target market selection is the process of deciding which market segments of the company should actively pursue to generate sales. After segmenting it various customers into segments has then found out those market segments which are highly profitable. The resort inorder to tap the honeymoon and wedding market has come out with two explicit packages targeting those clients and are looking for a unique and distinctive experience. On more generic terms the resort looks at targeting key opinion makers, corporate leaders, well traveled discerning, who have experience of finest luxury products and services, disposed towards high end luxury goods, looking for unique/distinctive experiences. Positioning Positioning is done to develop a unique selling proposition for the target segment. Positioning is the reason why hotels exist and why customers miss the company if it were to cease operation. Maradiva positioned itself as a destination resort. A company must be very specific in terms of its intended positioning or unique selling proposition if it wants to stand out among the clutter of choices confronting its potential customers. Chapter 3 Marketing strategies of Maradiva Maradiva majorly depends on foreign tourism, which states that the marketing stratergies can never be over emphasized. Marketing departing had the bonus of getting in the customers to the resort through various means and techniques. Maradiva knew that it cannot replicate the various marketing strategies being applied by other hotels as they offer a different sort of product and need to think out of the box in order to formulate new marketing strategies. 3.1 Pay for few nights and stay for more! Maradiva not only resorted to market themselves in the form of offers but also marketed themselves in the form of various packages which are designed as per the guest needs and preferences. Various packages like free night offer which includes, the guest has to pay for five nights and stay for seven or pay for seven nights and stay for nine nights etc. such type of offers are called tactical offers. Maradiva is well aware of the booking patterns that take place and in accordance with the same; various offers are launched during lean as well as peak season. During periods of low occupancy these tactical offers are provided to boost sales from their key markets mainly the major tour operators who provide maximum business to the hotel. they are implemented with an idea of generating occupancy levels so as to keep the business running comfortably. The tactical offers are designed in such a way so as to garner maximum amount of business during lean season and to maintain the influx of guests during peak season. As the tactical offers are different for different tour operators and vary a lot with the country as well, in U.K (5nights=10nights); France ( one spa treatment per person); 3.2 Mauritian Promotional Offer A tool to capitalize on domestic market Mauritius even though is a small island and the potential of domestic tourism is not phenomenal but every marketer feels that there is an opportunity in every situation. There is no dearth of people who want to live a life of luxury or would want to spend a day or two at a place where they feel theres value for money. Taking all that into consideration the Sales Marketing team of the resort came up with an offer known as Mauritian Promotion Offer in order to attract some local niche clientele. The offer was officially launched in December 2006 as a tactical offer but later owing to its potential it was later upgraded to an all year round offer. The offer included a rate of MRU 14,000 per night for a Luxury Villa with pool, with a HB meal plan inclusive in the package. 3.3 Wedding and Honeymooners Maradiva is the perfect place for romantic luxurious holidays, the ideal love nest for newlyweds. During earlier times when the resort just came into being they had a basic and simple marketing strategy: to market the hotel as a wedding or a honeymoon destination among young couples in the form of wedding and honeymoon packages which would include the accommodation along with the various formalities that need to be performed which is taken care of by the guest relation manager. The guests are also provided with various facilities like candlelit dinner, champagne breakfast, and massage for the groom and various beauty treatments for the bride. The honeymoon package would constitute of providing a 50% discount on the brides twin sharing rate along with various added values like coffee scrub, candlelit dinner, champagne breakfast, rose petal bath etc. 3.4 Affiliation packages Maradiva is affiliated to Leading group of small hotels, Great hotels of the world, Leading Spas f the world which helps the resort to generate more room nights than its competitors. The customers had the choice of choosing the package amongst a wide array of packages depending on their needs. For example a guest could choose a 5 day Maradiva Spa Stress Relief and Relaxation which would spread across a span of 5 days and has been carefully designed inorder to provide absolute relaxation to the guest. The package would encompass things like Level 1 2 of Yoga Meditation, Yoga Nidra, Trataka, Aroma Bath + Scrub Wrap, Surya Namaskar and Pehlwan Malish. The resort also boosted of a Golf Package as the resort was in close proximity to the Tamarina Golf Course. Recommendation In this section the researcher has illustrated various marketing stratergies implemented by Maradiva, Mauritius; and the SWOT analysis done by the researcher on the marketing strategies would enlisting few recommendations based on the knowledge and experience garnered during the operational and project stage of understudy: Maradiva should look at penetrating other new emerging markets such as South Africa, Middle East, Australia, Russia and India by developing a holistic approach, with the use of explicit marketing tools catering in specific to the particular market. By doing so the resort would be able to remove the dependability factor on its few restricted key markets and in turn would help them in being better prepared for unforeseen situations. With the growing spending power of people in the developing countries it would not be wrong to target those people who prefer travelling abroad during holidays by having country specific holiday packages in order to profit from situation. The hotel needs to take into consideration various countries trend for holidays. Internal marketing: Hotels should practice internal marketing; the hotel should motivate their customer contact employees and all their service people to work as a team to provide customer satisfaction. External marketing: The sales marketing should have good communication skills and should provide more interactive sessions to their clients should be able to market the product efficiently. The resort has done a lot to their micro site but the researcher still feels that the website can be made more appealing by adding blogs, interactive event / activity calendars, hotel guest scrapbooks, photo sharing contests, testimonials which helps in generating interests site stickiness ultimately increase the bookings. The airfare for a place like Mauritius is quite expensive and this discourages budget travellers from coming to the country. A possible solution for this could be combinable offers with airlines like Air Mauritius and Emirates which could help create a new segment of customers for the hotel. The hotel from its side needs to establish a healthy relationship with such airlines so that offers such as room fare inclusive of airfare would entice customers to come to the hotel. In this tech savvy age the resort can also look at establishing a database of e mail id of their loyal customers and can optimally use the e mail marketing technique in order to reward customers and offer lower rates to them which do not generally feature on the website. Conclusions Marketing has been and would always be an integral part of the smooth functioning of a hotel. Without proper marketing strategies there wouldnt be any guests coming to the property or even if they would be the hotel would be targeting the wrong sort of clientele to cater to. Marketing in hospitality industry is a balanced form of being an art with a lot of science behind every decision being taken under its domain. A more common view is that marketing activities are prepared in order to inform the customers about the products that they may enjoy or that they may improve their life in some way. Few marketers also see it as an opportunity for specific reasons like encouraging repeat purchases and building brand loyalty and affinity. Mauritius, having a very small population with large number of hotels coming up hospitality personnel are not afraid of losing their jobs. Their attitude is laid back, with the habit of procrastinating things. In order to attract and retain repeat guests it is necessary to primarily retain honest and loyal service personnel. The main reason why Maradiva had to roll down its shutters was its inability to attract guests to occupy its villas. There were a few minor errors with the marketing aspect. It was the price that did not suit many tourists pocket. Maradiva also faced a problem of its inventory being less i.e.only has villas. Other five star hotels which had a mixture of villas and rooms did roaring business at the same time. This clearly goes to show that the hotel should have done a more precise market survey before going into such a loss.
