The population growth brought the increasment of productive of the land.

Impacts of immigration had on American demography As the thought of immigration is being commenced in America, which means it is the first place that immigrates begin and it is the top of world the immigrates are living and all immigrations first started in America, where the first immigration are from northern and western Europe. This group of people was the first to combat racism because most of them were poor while fewer were rich. Demography in America resulted to major production and development of productive lands which interment increase the economic growth, whereby great number of immigration, the cost of labor and transportation was significantly to low price, this was brought up by immigration technologies. Impacts of immigration had on American economy The immigrates in the United State have less opportunities of getting jobs and also they are less involved on the participation on the labor in building the nation, but as newborns are matured in United State, later they cause a slit significant on earning and having employment opportunities.

Impact of immigration had on America’s political climate While the discrimination of employments to the immigrants was of higher aspect, because of the basis of race, gender, religion beliefs, color or national origins. The political practices occurred due to the equal employment opportunity, which was an economic issue and had the impact on nation economic growth. How different regions developed on economic growth and social systems The congressional leaders felt that the labor for each region has to be equally distributed among immigrant so that to strengthen each region. Each region developed different because of the geographical and the population growth from each region. The sections were created through the western, northern, and southern ham sphere, where the blacks have their section while the Indian and the white Americans has their section. Black America’s migrated to south while the Native American’s are the north. Therefore, the sections where are divided according to the population size and the geographical landscape. In the responses of growing illegal immigration, the domestic migrants underlook the consideration of provision of rules and regulation that addresses the concern, as it implies for immigrants. For the foreign policy, provides the mention of terrorism images, where the American’s heads create the policy that provides to the investigation organization such FBI and CIA a clear network to handle with such crimes.

Napoleon: Hero Persuasive Essay

A hero is someone who has a vision for a better future, acts on their visions, and has the perseverance to get through obstacles. Throughout history there have been countless heroes: Charlemagne, Alexander the Great, and many others. In 18th century France, during the French Revolution, one of the greatest heroes in history emerged. His name was Napoleon Bonaparte. Napoleon Bonaparte is considered a hero in French society because he fought his way to power and protected France, Napoleon was able to create unity and stability, both political and economic, in one of the most powerful nations in Europe at the time.Napoleon was not only an excellent leader, but also a dominate war strategist. Napoleon Bonaparte is a hero because he gave people rights and freedoms, forming an amazing educational system and reconstruction of France, along with his excellent skills with militarism, Napoleon became one of the greatest if not the greatest French leaders and heroes of all time. Napoleon starte d his military career as a junior officer in the French artillery; he was well noted for his commitment to his duty and his efficiency in his work.Napoleon was a passionate man who always put his own life on the line for his fellow comrades. Napoleon’s ability to risk himself in the line of duty to his country also solidifies his heroic status. Napoleon Bonaparte was a brave man and although he risked his life for many men he rarely made a foolish decision. Napoleon was unquestionably a born leader. Often in the harshest conditions he took this role to protect his fellow comrades. This is what made Napoleon an excellent war strategist. He wasn’t the type of man to sit back and watch.He took it upon himself to fight, again he established the true antithesis of hero, and by doing this meant that he had the ability to see what excactly was happening and how to counter all in the protection of France. Later in his military career he becomes general of the forces in Italy. The French were losing the war until Napoleon came along and restored the army to its former glory. In the decisive battle with Austria and their allies the Piedmonts, Napoleon and his army were outnumbered 38,000 to 63,000 but with his superior military strategy he crushed them and liberated Italy.This is a true testament to his abilities as a brilliant war strategist as well as further indoctrinating him as a hero. Napoleon established a civil code that lives on to this day across the world. It made all people equal before the law regardless of whether someone was of royal status or a peasant. Life under Napoleon’s regime was far better than people had under various other regimes. In Napoleonic influenced areas people were citizens not subjects. The people had some power over who was elected to government positions, even if it was mostly the wealthy.Life for many was still difficult in Napoleon’s regime but the one major difference was that the people could actually make something of themselves without regard to their nobility. Napoleon Bonaparte brought the perspective of getting a job based upon being skilled in a particular field of expertise. In other countries across Europe, unless you were of noble status or were undoubtedly wealthy enough to marry into a noble blood line then you were reduced to a life of mediocrity and hard work at best. Under Napoleon anyone could achieve what they wanted based on their experience, not their bloodline.When people say Napoleon was cruel and unfair remember that without him your linage is what defined your future not what you were capable of accomplishing. The French Revolution and Napoleon each played their role in the development of France.During much of the middle and late period of the French Revolution the young General Napoleon Bonaparte had been winning battles and gaining great popularity and respect among the French citizens. This was largely due to his image as a savior of the Revolution. (In 1 799, he participated in a coup d'etat which established a three person consulate with him as first consul.Under the newly established system of government, most of the power rested with Napoleon. On December 2, 1804, First Consul Bonaparte became Napoleon I, Emperor of the French, and his control over the government became complete. ) While Napoleon is often viewed in the perspective of his military prowess, he should also be considered one of history's great governors. Napoleon set out to make France the greatest nation of Europe. To accomplish his goals in restoring France Napoleon decided to rebuild churches, make banks, remodel the roads, and rewrite the legal system of France.When Napoleon became Emperor in December of 1804, he became even more concerned in the educational system thus becoming more interested in it. It is clear that the new system of education introduced by Napoleon had more than one purpose. It was intended, of course, to bestow an educated elite class that co uld help run the country and the military. It was also designed to provide for an increased middle class; a middle class that would be successful and therefor more obedient to the law. This was one of his main concerns when taking the throne.The last thing he wanted was his people to revolt and cause more chaos then necessary. As many people believe Napoleon is a hero, there are many that consider him a tyrant. The argument can be made that Napoleon let the power go to his head.An example of this is his tour in Egypt. Napoleon invaded Egypt for much of no good reason other than to gain fame. Although Napoleon was a great leader and war strategist he went to a country that had no guns or means of making them, a place with no way to get supplies do to the fact his ships were destroyed after landing in Egypt, and this lead to his downfall.Napoleon conquered Egypt because they had no real means of fighting against guns. While Napoleon stayed in Egypt he researched its history of which i s unknown to most of Europe. Napoleon created many forms of propaganda because he brings artist everywhere he adventures. Although Napoleon ruled Egypt that didn’t mean he had the resources to keep it eventually he was forced to flee do to Turkey’s army. So, Napoleon fled leaving his army of 35,000 troops to fend for themselves.When Napoleon returned to France he displayed his works of art and made it seem as it was a victory. To most this is extremely cruel, but some will argue it was for the best because at the time Frances government was falling apart and Napoleon restored the government from going into complete chaos. This could have led to another Reign Of Terror so was it for the best? Even when considered a tyrant for these actions by some his decisions further protected France’s interest. In conclusion, Napoleon Bonaparte, was more of a hero than tyrant.His thoughtful calculations and strategies as the leader of France gave him the right to be labeled a hero. Napoleon was able to create unity and stability, both political and economic, in one of the most powerful nations in Europe, he gave people rights and freedoms, forming an amazing educational system and reconstruction of France. His actions in battle and leadership instill heroic qualities that are hard to contest. Though many know of his diminutive stature his reputation as a hero is colossal.

An Analysis of Tone in The Road Not Taken, a Poem by Robert Frost

An Analysis of Tone in The Road Not Taken, a Poem by Robert Frost Robert Frosts work The Road Not Taken conveys a very simplistic, yet introspective theme. The poem describes the dilemmas and choices one must make in life, and how those specific decisions affect that person. Frost establishes this theme with an allegorical illustration of two paths in the woods. Later in the poem, the author reveals the attributes and personality of the main character as he or she contemplates past life choices. This characterization helps to bridge the gap between the reader and the character, allowing the poem to communicate a deeper resonance. Frost strengthens the readers figurative presence in the poem by presenting such emblematic diction and setting. The use of such devices again aid to the connection between the reader and the character-forcing Frosts message to become even more insightful. Robert Frost portrays a very pensive and impactful tone in his poem The Road Not Taken through means of symbolic imagery, representative setting, thorough characterizati on, and powerful diction, in order to encourage the reader to reflect upon his or her own life choices. One of the most significant elements of this poem is Frosts use of imagery. In the opening lines of the poem, the main character stops at a forked path in the forest, pondering which direction he or she will go. This part, being one of the most vital, symbolizes a choice needing to be made, most likely in life. Roads in literature often correlate with travel or a migration from one place to the next. So, the characters consideration about which road to take reveals a self-reflection the character has about which direction to go in life. Secondly, before the character continues his or her journey, he or she notes that the end of the first trail is covered by a sort of undergrowth, metaphorically indicating the perplexity of life and the inability to predict the consequence of life choices. The poem unmistakably exhibits this analysis in the first stanza, Two roads diverged in a yellow wood, / And sorry I could not travel both / And be one traveler, long I stood / And looked down one a s far as I could / To where it bent in the undergrowth (lines 1-5). Furthermore, it can be said that Frosts use of these figurative images are centralized to exemplify his tone of self-reflection and cogitation, as they boldly depict the importance of lifestyle decision-making. Another literary aspect Frost utilizes to express his tone is setting. In the poem, he writes, Two roads diverged in a yellow wood (line 1). The phrase a yellow wood may be an indication of the color the trees radiated. This suggests that the story takes place in the middle of autumn, most likely, contributing to the sense that time is running out-as in life-for the character. Here, Frost again outlines his tone as he demonstrates the characters rational contemplation and, eventually, regret. The author further establishes the setting as he indicates that the paths were not worn, even stating that one was grassy, providing a location of serenity and aesthetic beauty. This rendition of the setting applies a philosophical aspect to the poem, as it represents a life of innocence and potential. The forked trail could symbolize maturation and development, as the character is forced to choose which direction he or she wants to take his or her life. In the second stanza, it states, Then too k the other, as just as fair, / And having perhaps the better claim, / Because it was grassy and wanted wear (lines 6-8). In this part of the poem, it almost seems as if the character foolishly expected life to desire him or her to enter it, as the poem suggests the grass wanted to be worn down. This is probably one of the reasons why the character emotes regret later in the work. Again, Frost communicates his solemn and contemplative tone by familiarizing the reader with the characters experiences. Frost draws the reader into the story as he characterizes the man or woman standing in the woods. The character evidently appears conflicted throughout the story as he or she faces a dilemma and eventually has mixed emotions when one of the options were chosen. As the second stanza begins, the character states that he or she hastily chose the grassy trail which, according to the theme, is not wise. The author seems to suggest that the character is highly impulsive, while also adventurous, considering that he or she is wandering through the forest, almost aimlessly. As the story progresses, however, the character seems to be regretful of the choice he or she has made. For instance, as the character walks, he or she begins to seem fearful that the opposite path may have been more alluring or aesthetic. This becomes evident in the third stanza, stating, And both that morning equally lay / In leaves no step had trodden black. Oh, I kept the first for another day! Yet knowing how way lead s on to way, / I doubted if I should ever come back. (lines 11-15). Understanding the characters feelings again strengthens the relationship between the reader and the character, making the authors reflective tone and solemn message become even more compelling. The final figurative element Frost incorporates into the poem is diction. This becomes prominent in the final stanza, as it reveals the characters regrets. I shall be telling this with a sigh / Somewhere ages and ages hence: / Two roads diverged in a wood, and I-/ I took the one less traveled by, / And that has made all the difference. (lines 16-20). With use of the word sigh, Frost delineates the characters dissatisfaction with his or her choice. In the conclusion of the poem, the character, realizing that he or she had made the wrong choice, suggests that if the other path had been taken, he or she would have made the better choice. This ties in with Frosts tone as it is represented in the characters regrets. Robert Frosts short poem The Road Not Taken proves its literary merit through an intensely developed theme, as well as tone. Frost organizes an exceedingly philosophical and contemplative piece, through use of numerous literary devices. One of the most eminent include metaphorical imagery, such as autumn, a forest, and paths. He further exemplifies the tone as he employs setting and characterization. With these instruments, the poem is able to appeal to the reader, as it seemingly allows an immersion into the text. Finally, the authors application of diction contributes to what makes the text so captivating, as it lets the reader delve into the mind of the character. The poem The Road Not Taken by Robert Frost illustrates an insightful, yet regretful tone through use of setting, characterization, imagery, and diction, for the sole purpose of making the reader aware of the haste and intricacy of life.

Managerial Economics Article Essay Example | Topics and Well Written Essays - 250 words

Managerial Economics Article - Essay Example Huettner discusses the L&L Enterprises v. U.S Brass, a case in which the plaintiff held that the copper pipes and polybutylene pipes comprised of different antitrust product markets. On the other hand the defendant held that both copper pipes and polybutylene pipes were in similar antirust product market. Nonmetals, both the plaintiff and the defendant based their arguments on the provisions and guidelines by the Department of Justice. A wide range of microeconomic, antitrust economic as well as managerial economic literature contend that there lacks quantitative standard upon which close substitutes could be defined. Thus, practitioner divergence reflects the prevailing failure of economic theory to offer a quantitative definition of close substitutes. According to various economists, prices of close substitutes should keep track of each other such that they should have one price existing in the market. Nonetheless, practitioners are opposed to this rule. Perhaps, this explains why there has been unceasing controversy regarding the one-price rule in reference to Sun operating systems and Microsoft operating systems which sell at prices about 50 and 100 percent respectively, yet they are close substitutes. Basing on this argument, the author concludes that the one-price rule should be applied to close substitutes. This implies that close substitutes should have the same price, a price ration of one and should track each other closely over time. In addition, close substitutes should have a cross-price elasticity of unity. On the other hand, products that are not close substitutes should not keep track of each other closely over time. They should also have unequal prices as well as price ratio that differ from unity. Huettner, David A.

To paint the sunset is not only difficult but also a challenging task for which you have to make sure in mind what you are actually trying to pain. The sunset of the Sydney Opera House is a definite choice for artists. The best would be to visit the place and see it with your own eyes during the exotic sunset. Our eyes are one of the best creations of God, which absorb the beautiful scenery and stores in our mind this makes it easier to put it on canvas.

By Painting the Sydney opera with Chinese painting techniques, the children will get sensitive to colors.... Preparing the Canvas The size of the canvas is really important if you are painting the sunset at Sydney Opera house. Once you have selected your canvas, you need to select the medium you want to use for your paining, be it acrylic colors or water colors or only Chinese ink, you can use any medium to transfer your ideas on the canvas (Fong, 2001).

To wet your canvas you can use water, liquid white or oils. Layers should be applied to the canvas until it is completely wet. You can also use rice paper as your canvas which is widely used in Chinese paintings (Silbergeld, 1985).

Drama- Glengarry Glen Ross a play by David Mamet Essay

Drama- Glengarry Glen Ross a play by David Mamet - Essay Example The drama contains many idioms that also emphasize the moral teachings that the author talks about in the book. In the drama, the characters use pauses and stammers that make the language vibrant (Mamet 73). The personality of the characters in the drama often changes and it both repulses and amuses the audience. The characters in the drama also have a comic effect because of their exaggerated personalities. I believe that the drama is a piece that reminds people on the need of not losing their humanity and morality. This is especially those caused by the current hardship of the economic world. The drama clearly depicts the life of people struggling to become financially stable. The script of the author uses some styles that make it extremely difficult to execute in a play.

Critique on european imperialism on Heart of Darkness Article

Critique on european imperialism on Heart of Darkness - Article Example Marlow was employed to transport the ivory downriver; however, his major and important pressing assignment was to return Kurtz, of the ivory trader. This symbolic story is basically a story within a story, or known as the frame narrative. It also follows Marlow as he also recounts, from the dusk through to the late night, his main adventure into the Congo towards a group of men who boarded a ship anchored in the Thames Estuary. It should also be noted from a structuralist and main point of view that Marlow was also the name of a town which was situated on the Thames, upstream from London. (Conrad and Najder, 137) Set during the era of the heightened competition for all the imperial territories that most of the historians have termed the New Imperialism, the Heart of Darkness was loosely based on the Conrad's observations and experience during a six-month stint, in the year 1890, in the Congo as being an employee of a Belgian company. This was almost five years after the coferenece 1884-1885 Berlin, a meeting of different representatives of the European powers was held in order to establish the terms according to which most of the continent of Africa would be then divided among them. During this meeting, King Leopold II of Belgium, by playing skillfully with the jealousies and fears of the rival powers off one another, astonishingly tries to be managed in order to secure as his own personal property of the central Africa that is, a territory of about seventy-five times the size of the country which he had ruled. Under the various humanitarian pretenses, Leopold's agents, who had also begun th e process of the conquest several years earlier, also effectively turned the Congo Free State into a camp known as an enormous forced labor camp in order to do the extraction of ivory and, after this, the worldwide rubber also boom in the early 1890s following the popularization of the tire, rubber. Along with this, in order to outright the murders, the slave labor conditions also led to many deaths from the starvation and disease as well as a declining birth rate. During an era in which most of the Europeans viewed the imperialism as a legitimate, most of the falling circumstances of the Leopold's Congo also led to an international outrage. The Conservative demographic estimates therefore place the region's depopulation toll between the 1880 and 1920 at around 10 million people that is around half of the total population along with the worst of the carnage which was occurring between 1890 and 1910. Not much was really known outside the Africa about the conditions of the Leopold's r ule when Conrad was also there, but in the several upcoming years before he began writing the Heart of Darkness, in 1898, it also became an international scandal, and most of the regular reports appeared in the British and also in the European press denouncing all the abuses. When he was writing for Blackwood's Magazine, Britain was in its last years of his Victorian rule. Britain was one of the most powerful and also an influential nation on Earth; its Empire was also spread throughout Europe, Africa and Asia. Joseph Conrad was born in the Ukraine in 1857. African

Answer the Q Essay Example | Topics and Well Written Essays - 500 words

Answer the Q - Essay Example However, there is a requirement of developing an environment facilitating communication before problem arises since different cultures have varying degrees of social acceptance in contradicting opinions from their employers. Nonetheless, employees can have a feeling of not contradicting opinions from their management, or the management be involved actively in the process of making opinions being heard, thus establishing difficulty of eliciting reduced performance of the employees. Therefore, this essay focuses on discussing the significance of communication in the workplace to an organization. There is need for a clear communication in writing or verbally, between the employees and employers in order to eradicate challenges created by cultural barriers (Olynk and Widmar, 2). Communication in the work place has a significant contribution towards the business since it facilities functions such as negotiations involved in getting into business deals. On the other hand, effective communication in the workplace enables increasing effectiveness in communicating with manager and stakeholders, employees and customers. Solving a problem related to a long-term shortage of clear communication is creation of awareness that is preceded by active steps aimed at improving communication that initiated for benefits of employees and operations in the organization. Thus, an effective communication process manages both uncertainty and anxiety amongst strangers resulting from lack of understanding of each cultural expectation at play. Therefore, lack an effective process of communication lead s employees’ isolation: especially strangers from different ethnic groups. Based on what elements people employ, they go on to develop various methods of communication. Some of them develop verbal means; while others develop non-verbal means.

Privacy and Misuse of Private Information Essay

Privacy and Misuse of Private Information - Essay Example More specifically, the essay will address whether Clive can prevent publication of information regarding him, based on the law on breach of confidence and protection of personal information. Privacy and misuse of Private Information According to Crone et al (2002, p 93), the enactment of the law on breach of confidence and protection of personal information resulted from the need to protect personal secrets. In the recent years, people have used the law to prevent the publication of confidential information, especially in the mass media. In Clive’s case, the Daily Scandal wants to publish information about him. An action for breach of confidence can be the most appropriate to prevent against publication of personal information. Clive can easily obtain an injunction restraining the publication of information regarding cheating on his wife and attending the notorious club. He should take legal action, in which the court will apply an action called ‘blanket ban’ that prevents the magazine from publishing the photos. Under the law of breach of confidence, the Clive can prove several facts to prevent the daily scandal from publishing the information. One of these facts can be showing that the information contains adequate quality of confidence. The daily scandal has threatened to publish secret information about Clive, without his authority. ... This gives Clive the opportunity to take an action against them on the basis of ‘imputed confidential relationship.’ The court will grant the action of injunction since the differences between Clive and wife have not featured in the public domain (Aplin 2007, p 145). Tanya (2007, p 334) asserts that a person has the right to prevent the publication of this information since it does not affect the public in any way. Under this law, the media should not publish information about a person if the information does not touch on the public. Matters regarding marital unfaithfulness can be considered to be private. As such, they should not be made public; the information only refers to Clive and his wife. The media do not have an obligation to make public Clive’s personal information. Aplin observes that the law states that secrecy should not be exposed; instead, Clive and wife should be allowed to settle their differences using the due court process. Publicizing the wrong s of Clive will only worsen the relationship with his wife. As such, he can be in a position to deter the daily scandal from publicizing his photos and other information about him (Aplin 2007, p 150). He has the right to prevent the newspaper from publishing information regarding him since the information cannot be considered to be of public interest. Therefore, the ‘daily scandal’ cannot defend itself on grounds of ‘iniquity.’ The court does not intervene in the publication of public information concerning an iniquity (Stanley, 2009). In this case, the information concerning Clive attending the club and cheating on his wife cannot be regarded to be of public interest. Based on this, the daily scandal does not have an obligation to expose Clive’s conduct. Thus, they should not publicize the

Scarcity and Compassion Essay Example for Free

Scarcity and Compassion Essay According to the Oxford dictionary, scarcity is the same as shortage or presence in small numbers. In economics, scarcity is defined as the condition whereby human wants and needs exceed what is produced or what can be produced by the available resources (Harford, 2006). On the other hand, compassion is the belief in fairness in distribution of resources our humane aspects should not allow us to see others live without resources while we are capacitated to provide to them. Economists have pointed out over the disagreement between these two aspects as one calling for equitable distribution of resources to all persons while the other points out equal distribution of resources is impossible as there are no enough resources for everyone. Scarcity thus explains the presence of the rich and the poor. Compassion plays a big role as evidenced by empirical evidence on the ground especially on international level. Wealthy nations have always made attempts to make some of their resources available to poor nations (Harford, 2006). Note that, the resources given away as aid are not excess/ surplus resources per se. They are obtained from the taxpayer’s money whereby taxpayers could have allocated such resources in more economically viable options. Therefore, compassion by nations and/or on a household level continues to play great role in distribution of scarce resources. The fact that man is a social animal ties him to the idea of sharing his economic resources with the ones deprived of those resources. The knowledge by an individual of the suffering of another due to lack of resources either acting on a household level or any economic unit drives that individual to make decisions and/or implement policies that will favor the underprivileged according to his view. This explains why there are tax cuts and social benefits to the low income earners and unemployed respectively. Thus compassion plays and continues to play a significant role in the distribution of scarce resources.

Experimental Investigation of existing work. 1.4) General Information: The motivation i select this project title , is because in my organization they are looking for wireless network technology ,which can provide such applications like for delivering traffic for real-time applications such as Voice and data . Therefore IEEE 802.11 under point coordinate function PCF can satisfy the requirement, we will see that later. wireless local area network (WLAN), make people on the move to communicate with anyone and anywhere at anytime Caledonian college is one best example which is providing wireless service inside the college camps which allows the student to share data and web brows. The IEEE 802.11 WLAN has two different type of method channel accessing ,the distributed coordination function (DCF) and point coordination function (PCF). DCF is based on the carrier sense multiple access with collision avoidance (CSMA/CA) mechanism, while PCF is based on using the polling technique. The DCF mode of operation consists of two techniques for packet transmission. In the default its operate as a two-way handshaking technique where a positive acknowledgment is transmitted by the receiver station. (Stallings, 2007) . Fragmentation It is the process of break ­ing apart a packet into smaller pieces. A source (wireless Network Interface Card or access point) uses for fragmentation is to divide 802.11 frames into smaller pieces (fragments) that are sent separately to the destination. The fragments are all marked in a way that allows the destination device to put them back together again after it gets all the fragments. 1.5)The some of earliest work in data fragmentation IEEE802.11: Dynamic Fragmentation Scheme fro Rate -Adaptive WLAN.[7] Improving the Aggregate Throughput of Access Points in IEEE802.11Wireless LANs[26].

[20] Chapter 2 Literature Review Before we will go in depth of our title on data fragmentation under PCF mode , we must understand The basic building block of the WLAN network in IEEE 802.11., And our first objective will be covered in this section. 2.1) Background: In this section we will be discussing about wireless local area network (WLAN), which make people on the move to communicate with anyone and anywhere at anytime Caledonian college is one best example which is providing wireless service inside the college camps which allows the student to share data and web brows ,but increasing demand on portable computer for example Laptops and increasing communication equipment, its has responsibility of increasing in wireless network service. As we know this technology is working under protocols to control the service between users. Each type of wireless data network operates on a specific set of radio frequencies. For example, most Wi-Fi networks operate in a special band of radio frequencies around 2.4 GHz that have been reserved in most parts of the world for unlicensed point-to-point spread spectrum radio services. Other Wi-Fi systems use a different unlicensed band around 5 GHz. (Ross , 2008) ) IEEE MAC 802.11physical layer are defined in three type:2.2 Direct sequence spread spectrum (DSSS):its operating in the 2.4 GHz band at data rate of 1Mbps and 2Mbps, the number of channels available depend on the bandwidth. Frequency hopping spread spectrum(FHSS): operating in 2.4GHz at data rates of 1Mbps and 2Mbps, the available channel range is 23 in japan,70in USA. Infrared : data rate is 1Mbps and 2Mbps operating at a wavelength between 850and 950 nm. For IEEE 802.11 there are different standards as we can see ,but my study will be based on IEEE 802.11:[4] à ¢Ã¢â€š ¬Ã‚ ¢ IEEE 802.11: Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA) Medium Access Control (MAC), and 1 and 2 Mbps for DSSS, FHSS in 2.4 GHz band, and Infrared, ratified in 1997. à ¢Ã¢â€š ¬Ã‚ ¢ IEEE 802.11a: Works at 6, 9, 12, 18, 24, 36, 48 and 54 Mbps in 5GHz band, ratified in 1999. à ¢Ã¢â€š ¬Ã‚ ¢ IEEE 802.11b: Works at 5.5 and 11 Mbps in 2.4 GHz band, ratified in 1999. à ¢Ã¢â€š ¬Ã‚ ¢IEEE 802.11e: MAC enhancements for Quality of Service (QoS), work ongoing.( Stallings,2005) 2.3) There are four physical components standards for 802.11 network : Access point- Station- -Wireless Medium -Distribution System The basic structure block ,of the WLAN network is the 802.11 basic service set (BSS). A BSS defines a coverage area where all stations within the BSS connected. There are Two BSS network topologies: Independent BSS (IBSS) Networks Infrastructure BSS Networks The first one, In the independent BSS network stations, as it shown in figure(1) are communication directly with each other. Also its called the IBSS as ad-hoc network, used to communicate all station in infrastructure network together . An ad -hoc network operates from one station to another station immediately, without any help from other device, thats mean no need for permission to access. This operation is working by using the independent basic service set(IBSS) . Figure (1) :Independent Basic Service Set(IBSS) Second an Infrastructure Basic Service Set(BSS) as we can see in figure, (2) is a type of IEEE 802.11 network consists from stations and access point(AP), which are used to communicate all stations by (BSS).This will work when first station is sending the information to AP and than the AP forward this information to station which let the information pass to a wired node and the AP passes to fixed network.

In this section we understand the Fragmentation It is the process of break ­ing apart a packet into smaller pieces. Fragmentation is process that dividing large frame into several shorter frame. Each fragment consists of a MAC Layer header and frame check sequence (FCS), and a fragment number representing its ordered to position within the frame. Because the source station transmits each fragment independently, the receiving station reply with separate acknowledgement for each fragment (Yuguang and Kwon,2003 ) . All fragments are generate with equal size at same time, and all fragments will not change until they are transmitted in both PCF and DCF. 2.5) Why we are using this Technology? Using this technology because the Wireless LANs have high bit error rates. The probability of lasing frame is much higher for wireless links. 802.11 uses fragmentation to reduce the frame error rate. 2.6)The advantages and disadvantages of fragmentation: Advantages : To reliability of data exchange between the stations. The uses fragmentation to reduce the frame error rate and fragmentation for larger sized packets improves . Disadvantage: fragmentation will increase the overhead. (Tamer Khatteb,2009) 2.7) Distributed Coordination function (DCF) In 802.11, DCF also provides an optional way of transmitting data frames that involve transmission of special short RTS and CTS frames to the transmission of actual data frame. As shown in Fig(.3) an RTS frame is transmitted by a station, which needs to transmit a packet. When the destination receives the RTS frame, it will transmit a CTS frame after SIFS interval immediately following the reception of the RTS frame. Figure(3) Fragmentation The RTS/CTS access method (Anon.,2003) The source station is allowed to transmit its packet only if it receives the CTS correctly. Note that all the other stations are capable of updating the NAVs based on the RTS from the source station and the CTS from the destination station, which helps to combat the hidden terminal problems In fact, a station able to receive the CTS frames correctly, can avoid collisions even when it is unable to sense the data transmissions from the source station. If a collision occurs with two or more RTS frames, much less bandwidth is wasted when compared with the situations where larger data frames in collision.(Haitao ,et al.,2002) 2.8) The Fragmentation operation: A 802.11 data link layer is divided in two sub layers Logical Link Control (LLC) and Media Access Control(MAC). In 802.11, a MAC service data unit (MSDU) could be divided into a sequence of smaller MAC protocol data unit (MPDUs) as it (shown in figure 4). Fragmentation creates MPDUs smaller than the original MSDU length to increase the reliability, by increasing the probability of successful transmission of the MSDU in cases where channel characteristics limit reception reliability for longer frames. Fragmentation is able at each immediate transmitter. The process of combine MPDUs into a single MSDU is called as defragmentation . Defragmentation is adept at each immediate destination Only MPDUs with a unicast receiver address will be fragmented. Broadcast multicast frames shall not be fragmented even if their length exceeds a Fragmentation Threshold When a directed MSDU is received from the LLC with a length greater than a Fragmentation Threshold the MSDU shall be fragmented. The MSDU is divided into MPDUs. Each fragment is a frame no larger than a Fragmentation Threshold. (Yuguang and Kwon,2003 ). Figure( 4) MSDU divided into several MPDU. (Yuguang and Kwon,2003 ). ) Point Coordination function (PCF):2.9 PCF is working in combination with DCF as it shown in figure (5). PCF works suitable for high traffic load, In PCF, the AP acts in the role of the point coordinator, and it controls the medium access, If point coordinator hears there is no traffic after PIFS time gap, it sends out beacon frame Field to indicate length of time that PCF (polling) will be used instead of DCF (contention) during this time.(Stalling,2008) receiving stations must stop transmission for that amount of time The period during which PCF operates is called the contention-free period (CFP). Before the CFP begins, the AP operates under DCF, but it makes use of the priority inter-frame space (PIFS) to take hold the medium, and then sends out a beacon packet containing the duration of the CFP.(Stalling,2008) Figure (5). combination DCF PCF .(Stalling,2008) The fragmentation operation in PCF is same as DCF,but in PCF conation free period making different ,but because the DCF working with Contention period (CP) and PCF working with Contention free period(CFP) . (Yuguang Kwon,2003 ). There are some limitations on PCF which directly effetely the fragmentation, one of these limitation is the binary exponential back off , the frame need to wait even the medium is free ,because the binary exponential back off will double the random number from 15 to 1023 till the medium will be free, so this can effect the retransmit the frame in fragmentation . Other limitation in PCF has been designed to support time-limited for poor QoS performance. In particular the central pooling scheme is inefficient and complex which causes fall of the performance of PCF high-priority traffic under load, when a free station is allowed to send a frame of length between 0 and 2346 bytes, it introduce the difference of transmission time. (Dillip.2006). 2.1.0)Analysis The earliest work in data fragmentation IEEE802.11: In this section we will analysis ,In this paper(Abhishek,2003) we can analysis that polling in PCF causes overhead . In PCF, point coordinator (PC )is a central coordinator that schedules channel access for all other polling able stations in CFP. PC maintains list of poll able nodes in BSS. At beginning of CFP it polls all stations in Round Robin fashion. Nodes receiving poll respond back, either by transmitting data or there is no data frame. If station has no pending data, then it sends no frame. If station fails to do either then its result in polling time out at PC and PC resumes polling. When most stations have pending data, in order polling provide to ordered channel access and this can reduces collisions. But when few stations have pending data and rest are silent, this polling operation becomes major overhead, It adds unnecessary delay for stations with data, due to unsuccessful poll attempts for stations, with no pending data. For this reason resulting in throughput decreasi ng. Form the figure(6) we compares the overall throughput of network with 32 and 64 nodes having 16 nodes that have data to transmit. We can analysis that Effect of polling overhead is clearly visible(Abhishek,2003) Figure 6: the effect of (polling overhead )on network throughput From this paper, we can find the solution for pervious paper (Abhishek ,2003),by analysis that the overhead in PCF fragmentation is high ,so instead of allowing the transmission of multiple packets with a high data rate ,its possible to make MPDU large size to reduce the overheads caused by multiple packets transmission when channel condition is good. In Literature Review analysis we can describe it more clear(Yuguang and Kwon,2003 ). As we understand from this paper, that voice packets transmitted by use of PCF mode ,According to our analysis, PCF mode can well support packetized voice transmission using echo canceller fragmentation ,when the load are fragmented into small packets ,large fragment size such as 2000 or 2304 bits dose favour to voice traffic at the available bandwidth for data transmission.(Xiyan,al.,2003) In this paper ,we can analysis that, they propose a new rate adaptive MAC protocol with adynamic fragmentation. The major advance is the use of multiple fragmentation thresholds, for different rates to generate a new fragment from (remaining) MSDU only after the rate for next transmission is selected. With this scheme, the nodes with good channels can transmit more data than the ones with bad channel.( Byung,al.,2005) In this paper ,several methods been used to improve wireless network performance ,the result indicate as we can see in the figure (7),that the effect of fragmentation threshold can increase throughput and improve the wireless network performance, but how, the answer is when the bit error rate selected to be and the fragmentation threshold to be 256 bytes or 512 bytes, the result show that there is no any major effect on the network performance.(Walid Ajlouni,2006) figure (7),Effect of fragmentation, ( Walid Naim,2006) This paper ,proposes an adaptive control algorithm to tune the performance of IEEE802.11wireless LANs, so that traffic demands with different characteristics will be handled mostly by the MAC protocol that fits them. The algorithm aims is control the percentage of CFP duration within a super frame by measuring the throughput in PCF mode.(James,al.,2003) Chapter 3 Literature Review analysis T In this section we will be analysis ( 3.1 he out come from literature Review analysis: -Fragmentation It is the process of break ­ing apart a packet into smaller pieces. Fragmentation is process that dividing long frame to several shorter frame, Each fragment consists of a MAC Layer header, frame check sequence (FCS), and a fragment number indicating its ordered position within the frame. (Yuguang Kwon,2003 ). -The main reason we are using fragmentation is because the Wireless LANs have high bit error rates. -The period during which PCF operates is called the contention-free period (CFP). When most stations have pending data, in order polling provide ordered channel access and reduces collisions. But when few stations have pending data and rest are silent, this polling mechanism becomes major overhead, It adds unnecessary delay for stations . There are some limitations on PCF which directly effetely the fragmentation, one of these limitation is the binary exponential back off , the frame need to wait even the medium is free ,because the binary exponential back off will double the random number from 15 to 1023 till the medium will be free, so this can effect the retransmit the frame in fragmentation .(Class lecture ,Simulation Network Multimedia) 3.2 ) What will be solutions for Some Of above problems: 1) When there will be high overhead in PCF fragmentation is, so instead of allowing the transmission of multiple packets with a high data rate ,its possible to make MPDU large size to reduce the overheads caused by multiple packets transmission when channel condition is good. 2) when the bit error rate selected to be or the fragmentation threshold to be 16 bytes or 256 bytes, the result show that there is no any major effect on the network performance, so this maybe will be one of in our design and experiment we will select the above bit rat error than simulated it and observe the result.( Walid Naim,2006) 3) We go for IEEE 802.11e which introduces new coordination function called as a Hybrid Coordination Function (HCF) that is only useful for QoS network. The HCF supports channel access mechanisms, Enhanced Distributed Channel two additional Access (EDCA) for contention-based and HCF Coordination Channel Access (HCCA) for contention-free. And this stander will solve all problem with Polling and CW, which effect on fragmentation in PCF. ) Future Work:3.3 During my research i found that there is new standard been developed in 2007 , it know as IEEE 802.11e. To the best of our knowledge, there is very little literature , that deals with polling overhead in PCF .Other People have mentioned the problem earlier and there also come with some proposed solution to deal with it. also that people have mention the importance of polling for providing QoS service in IEEE 802.11 WLAN. New upcoming standard for QoS, IEEE 802.11e its called HCF (Byung,al.,2005) Chapter 4 Research Problem As i mention earliest the reason of selecting the study of data fragmentation effect in IEEE 802.11 under PCF mode is , is because in my organization they are looking for wireless network technology ,which can provide such applications like for delivering traffic for real-time applications such as Voice and data. There are some limitations on PCF which directly effetely the fragmentation, one of these limitation is the binary exponential back off , the frame need to wait even the medium is free ,because the binary exponential back off will double the random number from 15 to 1023 till the medium will be free, so this can effect the retransmit the frame in fragmentation . There for i found that IEEE 802.11 under PCF mode ,will not satisfy my Chapter 5 Design and Experiment Setup In This section i will be doing simulation , by using OPNET software as we can see in figure (8) to design and evaluate the performance of the IEEE 802.11 MAC protocol for wireless LANs. The aim of the project is to study the effect of data fragmentation in IEEE802.11under PCF mode. The main objectives of this experiment is to Study the effect of data fragmentation in PCF by choosing different bit rate error and observe the major effect on the network, as we analysis that using low bit error rate ,and give fragmentation value 256 bytes or 512bytes ,the result must show that there will be will no effect on the data transmission or on network performance. We can also do measuring response time (seconds) for PCF with 256 fragmentation and fixed data rate 5.5Mbps, and for page response time (seconds) for PCF with 256 fragmentations with fixed data rate 11Mbps.Finaly Compare the result obtain. Figure 8: WLAN Setup diagram in OPNET Chapter 6 Conclusion During my working in this project I have identify the effect of data fragmentation in IEEE802.11 under PCF in wireless network. I come out that this standard will help me in my organization to be used in library office only. The probability of lost frame is much higher for wireless links. Thats why fragmentation is used to Reduces amount of time medium is in use and Reduces probability of collisions .The IEEE 802.11 WLAN has two different channel accessing mechanisms, namely, the distributed coordination function (DCF) and point coordination function (PCF). We understand that When most stations have pending data, sequential polling provide ordered channel access and reduces collisions. But when few stations have pending data and rest are silent, this polling mechanism becomes major overhead, It adds unnecessary delay for stations with data. Also we understand that when there will be high overhead in PCF fragmentation is, so instead of allowing the transmission of multiple packets with a high data rate ,its possible to make MPDU large size to reduce the overheads caused by multiple packets transmission when channel condition is good. Anew standard has been developed in 2007 , it know as IEEE 802.11e. which support QoS. and can solve polling overhead in PCF.

Subject, Education, Truth :: Philosophy Papers

Subject, Education, Truth Two processes develop in human culture and society that implicate each other. The first is, according to Hegel, the development of universal experience and knowledge in any individual since individuals are never born complete as what they are supposed to be. The second is the subjectivization of the universal experience and knowledge into unique and singular forms of the self and self-consciousness. An analysis of these two processes in the history of philosophy has revealed the interconnections between the cognizing subject, truth and education and paideia. A hermeneutical principle of "self-care" that develops the skill of ruling and caring for others represents one of the traditions that includes these features in unity and determines a type of paideia. This principle is developed by Socratic, Platonic, Epicurean and Stoic morality, and was actualized by Descartes in his movement to the cogito. "Self-care" was considered in the 17th century as a condition of acquiring scientific k nowledge; later, however, it was labeled as egotism and individualism and replaced by self-cognition. Foucault gives proof of the necessity to revive the "self-care" principle in its initial sense as a foundation of the modern hermeneutical conception of upbringing. Hence, the role of philosophy as "an adviser" or "tutor" is to be revived in the process. How should I change my "self" to gain access to the truth? M. Foucault Hegel treats education as the alienation of natural Being and individual rising to universality, thus he correspondingly understands the person as "self" and as the subject of education. Subjectivity is here the definiteness of the universal. Aimed to freedom, it is able to unfold itself in culture and history, to develop itself on the basis of "the spirit and heart principle" to the extent of subjectivity, to the extent of judicial, moral, religious and scientific activity. It exhibits itself in active entity, internal activity and processuality as "inter-subjective" activity that develops in culture and history. The self-educating subjectivity becomes the highest universality, concrete Being of the universal, an individualisation of its content. In culture and society there develop two processes that meet each other. The first one, according to Hegel, is coming of a person to the universal experience and knowledge, because a person is never born the one s/he has to be. The second i s subjectivization of the universal experience and knowledge into unique and singular forms of the self and self-consciousness. Looking at education from these two points of view allows one to reveal hermeneutic meanings of education.

The Fish Gone Fishin :: Bishop Fish Essays

The Fish  - Gone Fishin' "The Fish" by Elizabeth Bishop is saturated with vivid imagery and abundant description, which help the reader visualize the action.     Bishop's use of imagery,   narration, and tone allow the reader to visualize the fish and create a bond with him, a bond in which the reader has a great deal   of admiration for the fish's plight.   The mental pictures created are, in fact, so brilliant that the reader believes incident actually happened to a real person, thus building respect from the reader to the fish.   Initially the reader is bombarded with an intense image of the fish; he is "tremendous,"   "battered," "venerable," and "homely."   The   reader is sympathetic with the fish's situation, and can relate because everyone has been fishing. Next, Bishop compares the fish to familiar household objects: "here and there / his brown skin hung in strips / like ancient wallpaper, / and its pattern of darker brown / was like wallpaper;" she uses two similes with common objects to create sympathy   for the captive.   Bishop then goes on to clearly illustrate what she means by "wallpaper": "shapes like full-blown roses / stained and lost through age."   She uses another simile here paired with descriptive phrases, and these effectively depict a personal image of the fish. She uses the familiar "wallpaper" comparison   because it is something the readers can relate to their own lives.   Also the "ancient wallpaper" analogy can refer to the fish's age. Although faded and aged he wit hstood the test of time, like the wallpaper.   Bishop uses highly descriptive words like "speckled" and "infested" to create an even clearer mental picture.   The word "terrible" is used to describe oxygen, and this is ironic because oxygen is usually beneficial, but in the case of the fish it is detrimental.   The use of   "terrible" allows the reader to visualize the fish gasping for breaths and fighting against the "terrible oxygen," permitting us to see the fish's predicament on his level.  Ã‚   The word frightening does essentially the same thing in the next phrase, "the frightening gills."   It creates a negative image of something (gills) usually considered favorable,   producing an intense visual with minimal words.  Ã‚   Another simile is used to help the reader picture the fish's struggle: "coarse white flesh packed in like feathers."   This wording intensifies the reader's initial view of the fish, and creates a visual, again, on the reader's level.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Bishop next relates to the fish on a personal basis: "I looked into his eyes.

The Benetton Group Case Study Essay -- Benetton Ad Campaign Social Iss

The Benetton Group Case Study The Controversy Continues Problem Identification Benetton, the world famous clothing producer, once again dives into social issues that the United States may not be ready for. The Italy based group is well known for their shocking world issue advertisements that only bear the company logo. In fact, Benetton’s advertisements traditionally do not feature the clothes it sells; only the issues play the lead role. After years of controversy over ads such as AIDS, war, interracial relationships, and priests kissing nuns, it may be time for Benetton to campaign about something other than controversial social issues, like clothes. On January 1, 2000, Benetton’s new advertising campaign wasn’t about sweaters or pants, but about convicted murderers that are on death row. The â€Å"death row† ads feature portraits of American death row inmates in prison uniforms with the slogan â€Å"Sentenced to Death†. The ads give the inmate’s name, date of birth, cr ime, and expected method of execution. Within the campaign, inmates also talk about topics ranging from their childhood to their dreams, everything except their victims. According to CNN, victims’ rights advocates are outraged as well as are the individuals that lost loved ones to the profiled inmates. Once again, Benetton is faced with another controversy that could perhaps worsen their already poor US market share. According to the New York Stock Exchange, where The Benetton Group is publicly traded, it seems that the company has lost over ten dollars per share since their peak of 50 15/16 in January. This decrease could be attributed to many things, but perhaps the most significant was the February announcement that Sears would immediately pull Benetton designed clothes from all 400 of its stores that had been selling the Benetton USA line. The Benetton USA line was specifically designed for Sears when the two companies joined last summer to introduce a new line of juniors , kids, and men’s apparel. Troubled by the campaign, Sears renegotiated its contract with Benetton to gain the right to preview future Benetton ad campaigns. A revised clause in the contract also gave Sears the ability to withdraw from the deal without penalty if the two parties were unable to agree on future campaigns, according to CNN. Regardless of these changes, the controversy was too significant for Sears to ignore due ... ...it could be done by using special warnings). The Benetton does just the opposite: it wants everybody to see it, because this is the only way they can change society (awareness). The ads may be perceived as psychoactive, and therefore ethically incorrect (e.g. the "Death Row" campaign had enormous negative impact on relatives of the murders' victims). The problems with the campaign eventually led to the departure of Toscani from the company (after 18 years of collaboration). The parties had claimed that it had nothing to do with the last campaign, but critics took it as Benetton's acknowledgement of wrongdoing. In the summer of 2000, the Benetton advertising practices have changed as well: they turned from using the death row as means of publicity, towards doing shows on fashion runways. Many of the industry observers anticipate that company will convert to more traditional fashion advertising in order to increase its sales. They predict it will help the stock as well (Sloat, 2000). The results of rethinking the advertising philosophy are yet to be seen. Judging by recent developments, the Benetton approach to social responsibility issues have not been entirely successful.

Blue Ocean Strategy Paper Essay

The blue ocean strategy in marketing is a distinctive method when it comes to building a customer base very different when it comes to competing within a certain type of industry. Instead of trying to compete in a crowded market place with existing companies, a blue ocean strategy will drive to create a complete new market segment that has no completion or other firms to compete against. In this day in age of technology and the emergence of it and globalization the importance of a blue ocean strategy has grown in recent years and in my essay I will explain the approach and how it is employed in the modern business environment, Blue ocean marketing strategy in marketing In today cluttered industries companies have to consider the four p’s of marketing when developing new offerings which include product, placement, price and promotion. In order to complete within their industries they must give consumers a certain value proposition for example a firm can offer a products at a very cost effective rate or at a higher quality than what is presently offered by other firms. In a blue ocean marketing strategy it would create an entirely new market causing a firm not having to worry about dealing with competition altogether. The blue ocean strategy, aims to create a new market place that will cause only one player in that industry eliminating any competition marketers build an entirely new product and service that is currently unknown to customers. In a case like this, it is vital to find effective ways to introduce and inform the public about the new product and service to develop awareness, interested and confidence. When product and service awareness has set in the new product will be positioned in point that provides no alternatives and allows much more effective branding tactics to be utilized. Modern examples of blue oceans moves There have been several notable blue oceans moves in modern business recently particularly in the technology realm the Nintendo Wii product shook up the gaming world when it was released 10yrs ago rather than compete with the ps3Â  and Xbox Nintendo decided to create a whole new gaming concept that used motion detectors instead of button controls the gaming system was received very well by gamers and built a new market with no direct competition I would require years of tech development for the company’s main rivals to offer similar products another notable blue market strategy occurred with the launch of toms shoes instead of just selling shoes toms created a unique business model that is essentially a hybrid of a charity and a shoe manufacturer it became the only company were a consumer could buy a pair of shoes and have a comparable pair donated to a third world country this strategy gives consumers an additional level of value that no other shoe manufacturer such as Nike jimmy Choo could match. Alternative red oceans move Red ocean strategy is the exact opposite move which positions a product in an already crowded market place while it does sound attractive there are many benefits to competing in a mature market there is already a strong customer education about the types of p/s being sold there dore companies do not need to spend a large budget on educating the consumer the main con of a red ocean move is that it can be hard to find a lucrative niche in well established markets just imagine trying to create a new soda brand that directly competes with coca cola it would be very unlikely that this new soda brand could upset the world’s largest soft drink supplier. Conclusion Many technology firms are now trying to implement blue ocean strategies to gain a competitive advantage in the market while there are many risks associated with their move it can be very lucrative if it successful ultimately marketers will need to weigh the potential benefits and risks that can emerge from taking the plunge into the blue ocean of business.

Cultural Diversity in Mauritius: Myth or Reality? Essay

Many people tend to dab the â€Å"Mauritian culture,† as a homogenous one. Some deny the cultural diversity in the island evolving harmoniously. In this regard, unity and diversity are interchangeable words. Constituting of ethnic groups and world religions like Christianity, Buddhism, Islam, co-existing with Hinduism and myriad spoken languages, the island’s people avow and practice different faiths which are reflected in our customs, rituals, norms, and festivals. Despite the contrasting way of life, the citizens remain essentially united. As Mauritians, we love to say that Mauritius is a twinkling model of unity in diversity. But then, we tend to do a lot of things which can only undermine the unity of this country. Unfortunately, diversity is used by many opportunistic politicians for disruptive purposes. After 45 years of independence, ethnicity remains the stratifying factor. Multicultural policies through funding religious groups are considered as empowering minority communities to voice out. In reality such policies have empowered not individuals but their â€Å"leaders† who owe their status and influence mainly to their affiliation with the government which benefits in its turn by manipulating the population and projecting their conventional image to the public through such platforms. At the 473rd anniversary of Maharana Pratab Singh and the creation of the Indian state of Rajasthan on Sunday 19th May 2013 at Indira Gandhi Cultural Centre, Phoenix the Prime Minister asserted that â€Å"Diversity should not be divisive. We are from different parts of India, but we are in the same boat. We should not make any difference between us,† as reported by the newspaper Le Dà ©fi Quoti dien. As a remedy, several solicit a secular state- a clear separation between religion and the state, which honestly, is not really the case in Mauritius who has lived an enigmatic development of its political history since the pronouncement of the United Nations, on the case furnished by ‘Resistans ek Alternativ’ militating against the exigency for a candidate of general elections to mention his ethnic belonging. Recently in the limelight, the Best Loser System was designed to provide â€Å"balanced† ethnic and political representation. Boasting about being â€Å"one nation, one people,† what is it about this â€Å"balanced† ethnic and political representation? Across several  decades since independence, haven’t we evolved and gained enough maturity to catabolise our ‘minority or ‘majority’ complex? If this does not show the erosion of that sense of togetherness in a culturally diverse society, then we wonder what it means. Wo uld a secular state mean that there will no longer be public holidays based on religious festivals, something that exist nowhere else in the world? Would we finally live in a flourishing democracy? Mindset. The Mauritian psyche is accustomed to doubt the unfamiliar and see â€Å"external† social groups as a menace. This demeanour is a real threat to national integration, peace, progress and development. This mentality is derived from fear, suspicion and mistrust in the country. To the newest generations, the 1999 riot in relation to Kaya’s death could be the reason that took a tragedy to uncover the truth of existing communal tension. Pretending that all is well in the society means doing very little to instil social cohesion. How can we expect a progressive change when the communal mentality is being perpetuated across generations? Official reform is one thing but changing the mindset of 1.3 million of people implies kissing impossibility. Nevertheless, many are optimistic and try to manoeuver the next generation through example and education. Despite all, for some, Mauritius has a marvellous timeline of peaceful cohabitation. We need not go back at the time of independence where we stood together as a one nation to steal a glance of that. April 2013 marked the flash floods which affected Mauritius causing large-scale disasters. The Mauritian solidarity and unity that we were to witness in providing the huge aid to the victims in need were indeed commendable, proving that we may have different religions and skin complexions, but we all belong to one human race. Alfred Adler said â€Å"There is a Law that man should love his neighbour as himself. In a few hundred years it should be as natural to mankind as breathing or the upright gait; but if he does not learn it he must perish.† Thus it seems imperative that all Mauritians should bury their petty differences and work collectively. We must create the foundation of a new Mauritius. We cannot be satisfied with the partly biased idea of a harmonious society, pressurisi ng us to believe in a stable nation. Common has it become in this interest-minded world to veil sinister intentions  behind this masquerade. Unity in diversity is not a slogan. It is a way of life. But will the forthcoming generation adopt this way of life?

Clinical Reflective Journal

Clinical Reflective Journal The first day I visited psychiatric ward, I felt nervous and excited because of the psychiatric ward which is totally different from general ward. I sensed that all patients who are walking in the corridor and some of them keep murmuring, and those behaviors I seen are seldom appearing in the general ward. However, after I found that they can communicate with others normally and have no aggressive behavior after approaching the patients.I learnt we should establish therapeutic relationship in the communication with patients via using non-judgmental, empathetic, active listening and supportive attitude. But I found difficulties in approaching patients who are introverted due to their unconcerned response. However, I think that we should obtain their confidence through persistent contact with them.Besides, I realized that being a psychiatric nurse, the observational skills is very importance, as the emotional or mental condition of psychiatric patient can be fluctuated between day and night. Therefore, nurses can implement corresponding precautions beforehand. In the private hospital, there are seldom opportunities to perform those skills, but there provide many chances for me to practice the professional skills and of injection and physical restraint.For instance, choosing which type of restrained device should be applied on the patient and related assessment we should made. Moreover, through the guidance of the nurse, I could realize the rationales behind the intervention, weakness in my performance and how to improve it. After caring of psychiatric patient in these two weeks, it helps clear up my misunderstanding of them and I hope that the nursing care of psychiatric patient can be helpful for them to return the society.

International business envioronment Essay Example | Topics and Well Written Essays - 3000 words

International business envioronment - Essay Example However what is required at the present is an understanding that things need to be properly aligned so that the problems which center the economic grounds cease to exist and thus provide all and sundry with a sigh of relief – one that is free of any form of anguish, economic disparity and woe, as one might put it. The chances of Germany coming back on the rails of success as far as the economic activities are concerned are manifold and one needs to understand as to what exactly are the undertakings on the part of the German authorities when the talk goes out loud of the German economy and the related measures that are being taken under the same auspices. The reasons as to why Germany is actually experiencing economic crisis lies in comprehending that the Germans are indeed the main reasons behind the very same. Only if the thinking mindset of the Germans as concerns to their economy and the future growth of the country in the long term perspective can change, there surely coul d be light at the end of the tunnel and thus positives could be drawn from the current quagmire in which Germany is in reality caught up.
