Biology 206 U3IP Research Paper Example | Topics and Well Written Essays - 750 words

Biology 206 U3IP - Research Paper Example The last codons, UAA, UAG, and UGA, signal the STOP, the conclusion of the translation (National Center for Biotechnology Information, 2000). What meaning do these mRNA codons have for protein synthesis? Explanation: Messenger RNA are the carriers of information. They form them into groups of 3 words, which identify specific amino acids that can then create a protein chain (Clancy & Brown , 2008). Did the two mutations result in a change in the final proteins? If so, describe the change. Response/ explanation: Yes, in the first mutation, eliminated the glycine and included an extra element of arginine. The second mutation was drastically different from the first. Glycine has returned, along with asparagines, but the other three positions have taken by three different sequences that are not reflective of the first sequence. In general, why might a change in amino acid sequence affect protein function? Explanation: Even a single change in amino acid sequences can affect the proteins ab ility to function. For example, the disease sickle cell anemia is caused by the change in only a single nucleotide in the DNA sequence can cause deformation in the red blood cells that can prevent it from carrying oxygen efficiently or successfully (Carter, 2004).

Include steps in meiosis that increase variability Include the process of fertilization. Explanation: Meiosis, in a basic definition is the process of cell division that lessens the number of chromosomes in the reproductive cells from diploid to haploid, which allows for the production of gametes in animals and spores in plants. Meiosis involves 2 steps, Meiosis I and Meiosis II, which then breaks into a number of phases, including interphase, metaphase, and telephase. Meiosis provides three specific mechanisms allowing for the diversifying of the genomes of offspring. Crossing Over, which occurs during meiosis when two chromosomes will pair up and exchange segments, with non-sister, cells, of their genetic materials. This allows for greater diversity to exist. Next is Random Assortment, basically, this process occurs when the when the â€Å"orientation† of the maternal and paternal homologues, within the first portion of the meiosis I, is genuinely random. Traits can be traded at randomly. The possible result of random assortment in humans can, more than, 8,000,000, potential, combinations (Chowdhury, Bois, Feingold,, Sherman & Cheung, 2009). Fertilizat ion, with the reduction of chromosomes it allows for the â€Å"

Contract Law Part 1 Essay Example | Topics and Well Written Essays - 2500 words

Contract Law Part 1 - Essay Example Initially, it was not given much recognition by the courts. It was left to Lord Denning to assess its significance and reintroduce it in Central London Property Trust Ltd v High Trees House Ltd. In this case the plaintiffs had leased out a number of apartments to the defendants. Thereupon, the World War had commenced. Consequently, the occupancy of these apartments reduced drastically. The defendants requested the plaintiffs and obtained a reduction in the lease amount. Afterwards, the World War came to an end and all the apartments were occupied. At this juncture, the plaintiffs demanded the originally agreed upon lease amount, for the period when the World War had been in progress. Lord Denning ruled that this was inequitable, because this would require the defendants to pay the full amount even though the apartments had been vacant2. Therefore, the plaintiffs were made subject to a promissory estoppel. It was held by the Court of Appeal in Williams v Roffey that where a party to an existing contract later agrees to pay an extra bonus in order to ensure that the other party performs his obligations under the contract, then that agreement is binding if the party agreeing to pay the bonus has thereby obtained some new practical advantage or has avoided a disadvantage. It was also held that executing an existing contractual obligation constitutes valid consideration, because it prevents the breaching of a contract with a third party3. Moreover, in CTN Cash and Carry Ltd v. Gallaher Ltd, it was decided that the practical benefit accruing to the promisor must be treated as consideration for extra payment4. In Central London Property Trust Ltd V. High Trees House Ltd, rent was reduced during World War II, as per the new agreement. After, the war was over, the landlord attempted to invoke the original contract, in order to obtain higher rent. The tenants invoked the principle of estoppel against the landlord and prevented him from enhancing the rent. In

Effect of the Energy Crisis on Pakistans Economy

Effect of the Energy Crisis on Pakistans Economy JAWAD KHAN Introduction: Energy crisis is defined as price rise of the energy resources or a great shortfall in the supply of the resources of energy. Usually it is referred to shortage of electricity, oil, natural gas, and other natural resources. Where the globalization has changed the world entirely, it emerged many issues but energy received significant attention from researchers. The demand for energy is increasing rapidly in this globalizing world with respect to supply; resultantly crisis for energy has emerged. Most of the countries are facing shortage of energy and consequently it is severely affecting the economic growth and social transformation. There are numerous views and ideas that potentially make linkage between energy and economic growth. Energy is considered as a backbone of any economy and plays an important role in the socio-economic development of a country. If there is not sufficient energy, industrialization will not take place, it is crucial for running industries and output units, f or residual and commercial use and for transportation, etc. As expansion in energy is expected to result higher growth similarly its shortage may hold back the growth process. In short, economy is vital for running all the resources and energy crisis directly influence all the sectors of economy such as agriculture sector, industrial sector, unemployment, poverty, lower GDP and higher inflation. Unfortunately, Pakistan is facing worst energy crisis in its history. Like other developing countries Pakistan is also an energy intensive growing economy, and as in most other non-oil producing countries its energy needs are met by large quantities of imports. Pakistan energy’s infrastructure is not well developed and said to be managed poorly. Despite of population growth, economic growth and increased demand during the past decades, no serious efforts were made for the generation of energy. Moreover electricity theft and transmission losses due to outdated infrastructure have worse ned the situation. Objective: The main objective of the study is to find out the extent of energy crisis impact on economic growth of Pakistan. Literature Review: Global Perspective: Article 1: For India and Indonesia, unidirectional Granger causality is found in the short run, while for Thailand and Philippines there is bidirectional causality that runs from energy to income. Energy, income and prices were mutually casual for Thailand and Philippines. (Asafu-Adjaye, 2000). Article 2: There is positive impact on economic growth by electricity consumption and bidirectional causality is found between electricity consumption and economic growth. It shows that greater electricity consumption leads to higher economic growth and similarly higher economic growth raise electricity consumption (Bayar, 2014). Article 3: Using error correction model and Granger non-causality tests, empirical results shows that in Pakistan case there runs unidirectional Grangers causality from coal to GDP, GDP to total energy consumption GDP to electricity consumption. In case of Bangladesh and Sri lanka, unidirectional causality runs from GDP to electricity consumption, there is causal direction from petroleum to GDP in case of Nepal. While no causality was found in case of India (Asghar, 2008). Article 4: Using integration tests on the panel data for ten Latin American countries, results show that for all the countries taken in sample, bidirectional causality exist between energy consumption and GDP. For further studies human capital, physical capital and labor can be included in variables as these are also important factors (Campo Sarmiento, 2013). Article 5: Applying various tests on panel data of Pakistan, India, Sri lanka, Bangladesh and Nepal, in short-run there is unidirectional causality that runs from GDP per capita to energy consumption per capita, while in long-run, there is negative relationship between these two (Noor Siddiqi, 2010). Article 6: There is causality found from energy consumption to GDP and GDP to energy consumption but it is found more extensively in developed OECD countries in compare to the developing non-OECD countries. It shows that impact of electricity consumption on GDP for developed countries is greater than developing countries of the world (Chontanawat, Hunt, Pierse, 2006). Article 7: Analysis indicates that energy consumption and GDP co integrate with each other. Scarcity of energy is a big constraint for the growth of an economy but when there is plentiful energy then it effects on economy is lessen (Stern D. I., 2010). Article 8: In short-run, energy consumption and GDP, and energy consumption and exports are co-integrated with each other. It shows that any crisis in energy will result in trade reduction which in turn will affect the GDP growth (Shakeel, Iqbal, Majeed, 2013). Article 9: Applying test on over 90 countries divided into 4 income groups, Ganger causality run from GDP to energy consumption in long run for high and low income groups, while bidirectional Gangers causality between GDP and energy consumption for lower middle and upper middle groups. While consistently there is a strong relationship for the sample countries between energy consumption and economic growth (Farhani Rejeb, 2012). Article 10: Taking 23 countries into sample and applying dynamic panel data GMM-system, there is unidirectional causality that runs from GDP per capita to energy consumption (Nayan, Kadir, Ahmad, Abdullah, 2013). Article 11: Co-integration for the real output, energy, capital and labor is found using bound test. The results prove causality from energy consumption to GDP for all the countries in both short-term long-run. This means economy of each country is dependent on energy and energy crisis will definitely result in reduction of economic growth (Muhammad Arshad Khan, 2007). From Developed Countries Perspective: Article 12: Granger causality test and co-integration analysis shows that energy consumption is strongly linked with economic activities as well as economic growth. Energy required to produce a GNP unit can be reduced by shifting to high quality of energy (Stern D. I., 2003). Article 13: Taking GDP and energy consumption as variables for France and applying VEC along geo-statistical methods, there is long-run unidirectional causality flow from energy consumption to economic growth (Amiri Zibaei, 2012). Article 14: Positive relationship between energy consumption and economic growth was found for Turkey from 1960-2008. This relationship over the past few years has strengthened which means economy dependency on energy (especially oil) has increased (Saatci Dumrul, 2013). Article 15: For Turkey, there is bidirectional causality between energy production and economic growth, which means increase in energy production will increase economic growth and same way around. Also bidirectional relationship between energy import and economic growth exists which means increase of energy amount to be imported will increase the economic activity and growth (Ozkan, Ãâ€"zkan, Kuyuk, 2012). Article 16: Johansen-Juselius co-integration methodology and Vector Error Correction Modeling results indicate a unidirectional causality that run from energy consumption to GDP. Thus any kind of possible short-fall in energy may affect the process of economic growth of Turkey (Soytas, Sari, Ozdemir, 2001). From Developing Countries Perspective: Article 17: For Malaysia, taking energy consumption as dependent variable and GDP, financial development, population as independent variables, results shows that economic growth and financial development influence energy consumption in short-run as well as long-run. Energy consumption is also influenced by population in long-run (Islam, Shahbaz, Ahmed, Alam, 2013). Article 18: Time series data from 1954 to 1997 for Taiwan, bidirectional causality is found between total energy consumption (coal, oil, natural gas and electricity) and economic growth (YangU, 2000). Article 19: For China, no co-integration was found between GDP and energy consumption by Johansen co-integration test while using Hsiao’s Granger causality there is bidirectional relationship between energy consumption and economic growth (Hou, 2009). Article 20: Studying the relationship between electricity consumption and economic growth for Tunisia during 1971-2007, bivariate vector auto-regression structure show existence of unidirectional causality is found from electricity consumption to economic growth (Chouaibi Abdasalem, 2009). Article 21: When examined with VECM and Johansen co-integration estimation, results shows unidirectional causality that runs from energy consumption to GDP while in long-run, feedback relationship exists between them. So for Tunisia, energy limits the economic growth. So any shocks to energy supply will badly effect the economic growth (Belloumi, 2009). Article 22: The analysis shows that real GDP is significantly impacted by the present as well as past changes in the supply of electricity. For every 1MWh increase in supply of electricity there is an extra output of Rs.88000-137000 (Morimoto Hope, 2001). From Under-developing Countries Perspective: Article 23: In the economy of Nigeria, there is a positive and strong relationship between national income and energy use. Ganger causality results bidirectional relationship between manufacturing capacity utilization energy consumption (Kabir, Zaku, A.A.Tukur, J.G, 2013). Article 24: For the period under study, results support that the Vietnam’s economic growth is not limited by the energy consumption. With increase in economic growth demand for energy use increases but not vice versa (Binh, 2011). From Pakistan Perspective: Article 25: In Pakistan, increase in energy supply will increase the economic growth while any crisis in energy supply will lead to barrier in economic growth. The impact of petroleum products and electricity is significantly high (Siddiqui, 2004). Article 26: Applying co-integration and Hsiao’s version of Granger causality on time series data from 1956 to 1996, results shows higher electricity consumption leads to economic growth while there is no feedback relationship. Increase and decrease in petroleum consumption does not affect economic growth but economic growth causes petroleum use. And there is no co-integration between gas consumption and economic growth (Aqeel butt, 2001). Article 27: In industries, cost of production may increase due to any shocks in the energy supply but investment in capital stock is not affected by these energy shocks (Mahmud, 2000). Article 28: With model of non-linear relationship, real output is negative affected by the change in prices of crude oil no matter these changes or less or more than the critical price of crude oil. Subsidies on electricity should be provided by the government (Kiani, 2011). Article 29: Electricity consumption and economic growth are in a long-run equilibrium relationship, electricity consumption do not leads to economic growth but economic growth leads to electricity consumption, as analyzed by Granger causality test with ARDL bounds testing approach (Shahbaz Feridun, 2011). Article 30: For GDP and oil consumption, and electricity and GDP there is a unidirectional relationship while in case of gas and GDP neutrality relationship is proved. Demand for oil consumption will increase by any future growth in agriculture sector (Mushtaq, Abbas, Abedullah, Ghafoor, 2007). Article 31: From 2007 to 2009 (post energy crisis period) performance is declined by the industries of textile, cement and engineering while during the same period the industries of sugar and chemical remain consistent. To save the industries, government of Pakistan should focus on energy sector (Khurshid Anwar, 2013). Article 32: A long-run relationship exists between electricity consumption and GDP. There is a unidirectional causality that runs from electricity use to economic growth; this means that any possible energy crisis may retard the process of economic growth in Pakistan. Government needs to invest in energy infrastructure in order to support economic growth (Yasmin, Javid, Ashraf, 2013). Article 33: Horizontal analysis of the major ratios of textile industry results that as compared to pre energy crisis period, the performance of textile industry is badly affected in post energy crisis period (Shah, Essrani, Shah, Rahat, 2013). Article 34: Analysis through multiple linear regression analysis of independent variables; electricity use and interest rate, shows that there is negative relationship between output of textile industry and energy use, and also out of textile industry and interest rate. Government should take serious actions for the survival of industries (Afzal, 2012). Article 35: From GDP to energy consumption there is one way causality resulted from Granger causality test while positive relationship also exists between them while tested by ordinary least squares method. GDP increases by 1.23% for 1% increase in energy consumption (Ahmad, Hayat, Hamad, Luqman, 2012). Article 36: Johansen co-integration test and VECM confirms that there is positive relationship between energy consumption and industrial output, bidirectional causality for oil consumption, unidirectional causality from electricity use to industrial output and from industrial output to coal consumption, while for gas consumption no causality exist (Qazi, Ahmed, Mudassar, 2012). Article 37: Using tools as Ganger causality tests, statistical analysis, correlation analysis, shows that GDP of Pakistan depend on energy consumption which include all forms i.e. electricity, oil, gas, coal. For trade there is unidirectional causality found from GDP to trade openness which means growth in GDP promotes trade openness (Chaudhry, Safdar, Farooq, 2012). Article 38: Any rise in prices of energy will affect the economic growth. As prices rises, manufacturers will either improve the quality standards or cut off the labor in order to survive in the market (Rashid, Azeem, Ramzan, 2012). Article 39: Bound testing approach to co-integration and Ganger causality test results bidirectional causality between economic growth and energy consumption in short-run, while unidirectional causality from economic growth to energy consumption in long-run. Frequent changes in energy price also impact economic growth (Adnan Riaz, 2008). Article 40: By applying Structural Vector Auto-regression, results reveal that economic growth increases the demand for labor force, capital stock and energy consumption. Pakistan government needs to supply energy at affordable prices to facilitate growth in economic activities (Zeshan Vaqar, 2013).

Courts Essays -- essays research papers

The jurisdiction of the federal courts is defined in Article III, Section 2, of the Constitution, as extending in law and equity to all cases arising under the Constitution and federal legislation; to controversies to which the U.S. shall be a party, including those arising from treaties with other governments; to admiralty and maritime cases; to controversies between states; to controversies between a state, or its citizens, and foreign governments or their subjects; and to controversies between the citizens of one state and citizens of another state. The federal courts were also originally invested with jurisdiction over controversies between citizens of one state and the government of another state; the 11th Amendment (ratified February 7, 1795), however, removed from federal jurisdiction those cases in which the citizens of one state were plaintiffs and the government of another state was the defendant. The amendment did not disturb the jurisdiction of the federal courts in case s in which a state government is a plaintiff and a citizen of another state, the defendant. Federal courts have exclusive jurisdiction in patent and copyright cases; and by congressional enactment in 1898, federal courts were vested with original jurisdiction in bankruptcy cases. The courts established under the powers granted by Article III, Sections 1 and 2, of the Constitution are known as constitutional courts. Judges of constitutional courts are appointed for life by the president with the approval of the Senate. These courts are the district courts, tribunals of general original jurisdiction; the courts of appeals (before 1948, circuit courts of appeals), exercising appellate jurisdiction over the district courts; and the Supreme Court.   Ã‚  Ã‚  Ã‚  Ã‚  A district court functions in each of the more than 90 federal judicial districts and in the District of Columbia. A court of appeals functions in each of the 11 federal judicial circuits and in the District of Columbia; there is also a more specialized court with nationwide jurisdiction known as the court of appeals for the federal circuit. The federal district court and the court of appeals of the District of Columbia perform functions discharged in the states by state courts. All lower federal cour ts operate under uniform rules of procedure promulgated by the Supreme Court. The Supreme Court is the highest ap... ...tes, the same courts of original jurisdiction deal with both civil and criminal cases; these courts usually have two levels, one handling misdemeanors and civil claims under $5000, the other handling felonies and civil claims over $5000. Between the lower courts and the supreme appellate courts, in a number of states, are intermediate appellate courts which, like the federal courts of appeals, provide speedier justice for litigants by disposing of a large number of cases that otherwise would be added to the overcrowded calendars of the higher courts. Courts of last resort, the highest appellate tribunals of the states in criminal and civil cases and in law and equity, are generally called supreme courts. In New York state, however, the Supreme Court is a trial court; the highest appellate court of New York, as well as of Maryland, is called the Court of Appeals. The state court systems also include a number of minor courts with limited jurisdiction. These courts dispose of minor offenses and relatively small civil actions. Included in this classification are police and municipal courts in cities and larger towns and the courts presided over by justices of the peace in rural areas.

To What Extent Did Lenin Establish Communism in Russia Fro 1920-1924?

To what extent did Lenin establish Communism in Russia from 1920-1924? From an early age, Lenin opposed the Romanov autocratic regime, even more so following the execution of his brother for the assassination of Tsar Alexander III. Lenin was an avid follower of the writings of Karl Marx and believed communism was the way forward. He believed that everything should be owned by the government and then distributed evenly amongst the people. During the February 1917 revolution in Russia, Lenin was in exile. He knew his right-hand man Trotsky would tell him when the time was right to come back to Russia.The end of the February Revolution led to the end of the Romanov dynasty and to the Provisional Government under Lvov and Kerensky. It also meant the return of Lenin. By October 1917, he felt the time was right for a Bolshevik revolution. It was relatively bloodless and Lenin assumed the responsibility of governing Russia. Between 1920 and 1924, Lenin and the Bolsheviks attempted to shape the destiny of Russia and establish communism. He said, ‘’History will never forgive us if we do not assume power now’’.Having taking over Russia, Lenin now had the challenge of holding on to power. The first thing he did was put a decree on land. This meant that peasants were allowed take over private land. Therefore, landlords weren’t very happy about this. He also abolished the Assembly. Lenin believed in a one party dictatorship and this step was necessary for it to happen. It was at this time that the Bolsheviks became known as Communists. In an attempt to make all people equal, everyone was to be addressed at ‘’Comrade’’. Lenin’s next step now was to make peace.The slogan of the Communists was ‘’Peace, bread, land’’. From fighting in World War I, Russia was on the verge of bankruptcy. Lenin knew something had to be done. The Russians were losing battle after battle and the country co uldn’t take any more of it. Also, the army was in disarray. Soldiers were losing heart and most of them were killed. Lenin realised this had to be stopped. He was pragmatic and knew the country couldn’t take it much longer. Therefore, Lenin signed a peace agreement with Germany. This was known as the Brest-Litovsk Treaty or The Shameful Treaty.Although it obtained peace in Russia, it involved in the country losing a quarter of its land and population, eighty per cent of its coal mines and thirty three per cent of it farming land and manufacturing industry. Lenin insisted the survival of the communist regime depended on it! Lenin however was faced with opposition, collectively known as the ‘’Whites’’. These included a disarray of groups such as social revolutionaries, supporters of the Provisional Government, landlords, tsarist supporters and many more. This gave rise to a civil war in Russia. The war was the ‘’Reds’â€℠¢ vs. he ‘’Whites’’. The Reds had many more advantages than the Whites. The Red Army were under Trotsky, a very skilled military tactician. The Reds were being attacked from every direction by the Whites with the help of the Allied Powers. However, the Reds greatest threat was Pilsudski and his Polish army. This was the only battle were Lenin had peace negotiations and were he lost some of Russian territory. As time passed, Allied support lessened. This was a big disadvantage for the Whites. The Reds had another advantage over the Whites, they were more united.The Whites had many different groups who wanted and fought for different things so it didn’t work in their favour. One further advantage for the Reds was that they were located in central Russia, which was capable of being defended. This ended in victory for the Reds. During the civil war, Lenin took control of economic and political problems. He followed a policy of War Communism. This policy saw Lenin ensure that all industry and agriculture within the Communist –controlled territory was geared solely towards the war effort.All of the surplus crops that were grown by the farmers were requisitioned by the government and distributed between the workers and soldiers. Food detachments were sent to the countryside to get the food. This was very unpopular with the farmers. They began to cut back in grain production so eventually, Russia experienced a famine. An estimation of between five and seven million people died due to hunger. The Red Terror was set up by the Cheka. The Cheka were a secret police force set up to arrest and execute people who they believed opposed Lenin and the Communists.Any opposition to Lenin was dealt with legalised acts of brutality. It was a systematic terror designed to ensure the continuation of Communist rule. The Kronstadt Rising gave the Cheka a great opportunity to put down the revolt. The naval soldiers that were involved were brutall y treated and were easily defeated. Following the end of the Civil War, Lenin knew that change needed to be made. He ended War Communism and brought in the New Economic Policy. There was serious discontent which undermined support for Communism.The NEP ended the requisition of food from the peasants, peasants were now allowed to sell their surplus for profit and private enterprise was allowed in small factories. Although many of these terms were contrary to Communist beliefs, Lenin said that ‘’we must take a step backwards in order to go two steps forward at a later date’’. Although Lenin did not live to see the full effects of the New Economic Policy, he had a great effect on the Russians and established the first ever Communist state. Lenin took many steps in order for Russia to become a Communist state.

A Case Study of Arvind Mills

A case study on Arvind Mills Ltd Supply Chain A very distinct feature of Arvind Mills Ltd is the fact that its brands work across multiple channels, price points and customer segments. These are brands that are distinctive and relevant across diverse customer segments. Some of the brands under Arvind Mills are: Wrangler, Excalibur, Flying Machine, Newport, Ruf & Tuf, Arrow, Izod etc and its customers include Levis, Lee, Tommy Hilfiger etc.The supply network finally reaches the customer touch points through over 275 stand alone brand stores across the country and more than 975 counters selling multi brand retail outlets an key accounts across India. Arvind Mills Ltd is one of the largest denim manufacturers in the world and has configured its supply chain based on â€Å"push† system. Under normal operating conditions, Arvind manufactures denim â€Å"sorts† based on monthly forecast to stock at various warehouses.As Arvind Mills â€Å"pushes† its products (sorts) t o ware-houses, actual selling takes place on an ongoing basis with the â€Å"sold sorts† are being replaced subsequently. The â€Å"Push† system operates under the â€Å"make-to-stock† environment. While the system has worked efficiently at Arvind for years it becomes difficult for a company to follow the same where a high demand fluctuation exists. A Push-based supply chain accumulates excessive inventory (â€Å"cycle stock† and â€Å"work-in-process†) by the time it responds to the changing demand.In addition, since long-term forecast plays an important role, it is difficult to match supply with variable demand. â€Å"Push† supply chain also entails larger production batches, incompatible for catering demand of short quantity. Another interesting feature of the supply chain is the intense reach Arvind Mills is targeting. With increasing disposable income available in the rural areas as well, the company is trying to make shirts at affordab le rates available at grocery stores and petrol pumps. It has also started selling shirt bits instead of multi meter long rolls which once dominated the retail shelves.

Cuba, Battleground of Opposing Views essays

Cuba, Battleground of Opposing Views essays The Cuban Missile Crisis of October 1962 was one of the turning points of the Cold War between the United States and the Soviet Union. At that time the two superpowers came closest to war than they had ever been, most likely with nuclear weapons. The actual crisis started when on October 14th 1962, a U-2 airplane brought back pictures of medium-range missile bases that were under construction around San Cristobal, on the west of the island. What followed was a face-off between the leaders of the two superpowers, U.S. President John F. Kennedy and Soviet leader Nikita Khrushchev. Kennedy reacted to the missile threat by imposing a naval blockade on Cub, preventing further missile deployment. The American blockade came into place on the morning of October 24th. With several Soviet ships approaching the blockade, there was great fear that if a ship did not halt, the U.S. battleships would have to be forced to fire and by doing this unleashing a nuclear war. Luckily the ships did stop or turn around. Matters got hectic once more when on October 27th an American U-2 was shot down by a SAM missile over Cuba and its pilot killed. Another American reconnaissance plane was hit by Cuban anti-aircraft guns, but it managed to fly home. If this plane had been shot down as well, the U.S. would probably have retaliated. But in the end neither leader wanted to engage in a nuclear war and a treaty was negotiated. This treaty stated that the Soviets would withdraw their missiles from Cuba if the Americans pledged not to invade Cuba. Part of the deal was also the removal of Soviet bombers from Cuba and the removal of the Jupiters from Turkey although not within any public deal. A potentially disastrous conflict was averted. In this paper I will try to explain what caused the Cuban Missile Crisis and why it was prevented. To do this I need to look at both Kennedys and Khrushchevs foreign policies. The task in our block book is entitled ...

Pcs Are Better Than Macs For Home Users Essays - Steve Jobs

Pcs Are Better Than Macs For Home Users Essays - Steve Jobs Pcs Are Better Than Macs For Home Users For years, Macs and PCs have been competing for home users. Apple has recently released the new iMac, and the notebook version of the iMac the iBook. Even though several years ago, Macs were better than PCs, now, PCs are better than Macs for home users in terms of performance and expansion options. To some consumers, performance is often the most important factor in buying a computer. Performance doesnt necessarily mean how well the computer performs potentially, but only on specific tasks. Both iBook and iMac are designed for home users, most of whom neither care about number of floating-point operations per second, nor know what it means. Very few home users will pay $500 for Photoshop 5.0 to edit photos on their PC. The more likely uses for home computers are: word processing, browsing the Internet, and 3-D gaming. Since the most popular word processor is developed by Microsoft and allegedly optimized for Windows, it would be unfair to compare the Mac version of MS Word with the Windows version. However, comparing the performance in 3-D games and the Internet is fair. Even though PC Magazine specializes in PCs, it reviewed the iBook as soon as it came out. The article focused on performance of the iBook and compared it to a similar IBM-compatible notebook. Since there are no new IBM-compatible notebooks that match iBooks specifications, PC Magazine decided to use the notebook they believed to be closest to iBook the IBM ThinkPad iSeries 1480. They have very few similarities: the both notebooks are available in different colors, and neither notebook has the fastest processor from its platform. Apple claims that its notebooks are up to twice as fast as comparable Microsoft Windows-based portables (qtd. in Hill 53). This statement is very vague it doesnt say how they compared the portables, and what Apple meant by comparable. Since similar statements have been made about iMac, speed will be discussed in the next section; for now, lets make sure that PC Magazine selected an appropriate notebook. The G3 processor from the iBook is one generation behind Mac desktops, whereas the ThinkPads Celeron is two generations behind other IBM-compatible notebooks. Even though Celeron is somewhat obsolete, it runs at 466 MHz versus G3s 300 MHz. Since neither processor is top-of-the-line, and both notebooks are in the same price range, it is safe to conclude that the two notebooks are comparable. Apple declares that fast, easy access to the Internet is among the features [that] made the world fall in love with the iMac (Apple). As mentioned earlier, the Internet performance is one of the uses for home computers and should be thoroughly tested. In their review, PC Magazine uses i_Bench to test the Internet performance. According to i_Bench tests, ThinkPad outperforms the iBook on almost every test (Hill 53). The only exception is the test of QuickTime Transition Effects the iBook is faster than the ThinkPad (Hill 53). Apples QuickTime is one of many formats for viewing compressed video on the Internet and is rarely used because of poor compression quality. QuickTime should not be used to test the computers performance for several reasons: it is rarely used, and is most likely optimized for Macs. On the other hand, The Java Virtual Machine test should be looked at more carefully. Java is a platform-independent programming language originally designed by Sun Corporation for another operating system, and is currently used for writing programs for the Internet. This test runs several Java programs within a browser, which simulates ordinary Internet browsing better than QuickTime. The ThinkPad impressively outperformed the iBook with the a score of 43,766 versus just 23,872 (Hill 53). Comparing the iMacs with IBM-compatible desktops creates the same problem finding the PC that is comparable to the iMac. Dave Glue, a programming student, sums up this problem in one sentence: If you're going to downgrade the PC to exactly match the iMac's MHz rating and hard disk, you'll have a significantly cheaper PC than the iMac. Even when comparing computers of equal price, another problem appears they run two completely different operating systems. Apple uses BYTEmark (Apple), which tests the processors integer and floating point capabilities (Byte) to

3 Problems with Introducing Sayings and Questions

3 Problems with Introducing Sayings and Questions 3 Problems with Introducing Sayings and Questions 3 Problems with Introducing Sayings and Questions By Mark Nichol Often, an incorrect form of punctuation is deployed to set off the introduction of a saying or a question from the quoted material itself. The following sentences demonstrate various errors related to this issue, and discussions and revisions explain the problem and illustrate one or more solutions. 1. The old saying, â€Å"What gets rewarded gets done,† is as true with risk as with any other activity. Setting the quoted saying off with commas implies that it is equivalent to â€Å"the old saying,† meaning that it is the old saying- the only one in existence. However, that phrase and the quotation are appositives; they both describe the same thing (a saying- one of many), so no internal punctuation is required: â€Å"The old saying ‘What gets rewarded gets done’ is as true with risk as with any other activity.† 2. From that perspective, we should ask: Are executives looking at portfolio management? Do they understand how the budgeting process works? Do they understand how the capital-allocation process works? A colon should not be used here, because that punctuation mark serves as a sort of soft period, indicating the end of an independent clause and at the same time signaling that what follows will be some form of an extension of that clause. But what precedes the colon is not an independent clause, so that initial part of the sentence should be extended to become an independent clause: â€Å"From that perspective, we should ask the following questions: ‘Are executives looking at portfolio management?’ ‘Do they understand how the budgeting process works?’ ‘Do they understand how the capital-allocation process works?’† (Note, too, that because the questions are conjectural utterances, they should also be framed in quotation marks.) Alternatively, a comma can replace the colon: â€Å"From that perspective, we should ask, ‘Are executives looking at portfolio management?’ ‘Do they understand how the budgeting process works?’ ‘Do they understand how the capital-allocation process works?’† 3. When we speak to heads of audit of organizations in the health care sector, many ask the same question, Where do we start? This sentence illustrates a problem opposite to that discussed in the previous example. What precedes â€Å"Where do we start?† is a complete statement, so a colon should replace the final comma to set up the question: â€Å"When we speak to heads of audit of organizations in the health care sector, many ask the same question: ‘Where do we start?’† (Again, the question itself should be enclosed in quotation marks as well.)

Peoples Services Inc. by Muhammad Case Study Example | Topics and Well Written Essays - 1000 words

Peoples Services Inc. by Muhammad - Case Study Example Her supervisor Haleema realizes the changing attitude and decides to intervene. Â  According to Muhammad (2012), Qureshi starts taking longer lunch breaks meaning she was late to come back to the office for 15-20 minutes. Haleema noticed that after the lunch break, Qureshi was less productive, and spent some time dosing on the desk. She became too unproductive and sensitive to her colleagues who had to repeat her poor work. Later, Qureshi developed a habit of calling in sick with stomach flu. At one time, her daughter calls to say Qureshi is sick in bed. One afternoon, Haleema realized that Qureshi's breath smelt of strong mint and suspected she was drunk. Having given Qureshi many warnings, Haleema felt she needed to act because her attitude and performance affected everyone around her. Muhammad (2012) notes that Qureshi even asked for a departmental transfer arguing that she needed a less busy office. Haleema felt she needed to fire Qureshi because she never opened up her problems, and she seemed to deteriorate in her performance. However, they had to contact Employee Assistant Program (EAP) before firing her. Â  Haleema would land into legal problems for firing Qureshi without consulting EAP. Richard et al. (2009) argue that the EAP requires some alcohol or drug testing was done on any employee before terminating her from office. An alcoholic worker faces protection from Acts protecting people with disabilities and medical problems. Haleema should help Qureshi in seeking professional help before firing her. The law does not encourage alcohol abuse at a workplace. However, it encourages the employer to help the victim obtain treatment. Therefore, the Qureshi may sue Haleema first for not doing the alcohol test, and secondly for not intervening for a professional help. Although it may be expensive, the employer should seek legal help before taking action against Qureshi.

Immigration Essay Example | Topics and Well Written Essays - 750 words - 7

Immigration - Essay Example The opponents of illegal immigration also say that illegal immigrants are burdens to law-abiding citizens. While the majority tends to think that illegal immigration has a negative influence only, in reality, it can have positive influence as well. More specifically, illegal immigration can make a positive economic contribution. As it follows from the research described in the article titled Illegal Immigration: A Positive Economic Contribution to the United States by Nadadur (2009), illegal immigrants have a significant positive impact on the economic growth of the USA. After conducting a qualitative research on the fiscal impact of illegal immigration taking into account the paid taxes and the costs from the use of social services imposed on the society, the author of the article draws the conclusion that despite the fact illegal immigrants impose a certain challenge at both local and state levels, their contribution to the economy should be regarded as positive due to the fact they take part in business development and job creation (Nadadur, 2009). When it comes to immigrants themselves, it appears that they face significant challenges posed by their illegal status in the country they choose. In accordance with Rhodes et al. (2015), certain challenges are posed by local immigration enforcement policies on immigrants well-being. In particular, the authors of the article state laws and policies aimed at regulating and controlling the illegal immigrant populations limit illegal immigrants opportunities to use public services, such as education health services. For instance, Hispanic/Latino mothers receive inadequate care compared to other non-Hispanic mothers. Also, children of illegal immigrants face challenges posed on their mental health. Specifically, children whose parents were deported tend to suffer mentally unlike those whose parents had not been deported from the country (Allan, Cisneros and Tellez,

Should Veil be Banned in the UK Essay Example | Topics and Well Written Essays - 2000 words

Should Veil be Banned in the UK - Essay Example Considering Sura 7:46, a veil acts as a separation between the resident of Heaven and the resident of Hell. In Sura 19: 16-17, a veil is remarked as the symbol of sovereignty and purity. Other explanations in the Quran also describe veil as a separation of evil with the good (Amer, 2000). On this note of an affirmative definition of veiling one shall think that why veil should be banned in the UK or any other country contradicting preaches of Islam and the belief of Islamic women. It was in the year 2006, when Mr. Jack Straw, a leader of the House of Commons in the UK stated ‘Hijab’ to increase the differences between Islamic religion and other religious groups and remarked the practice as a â€Å"visible statement of separation†. This incident was led by the suspension of an assistant teacher wearing veil in her workplace (Sultan-ul-Qalam, 2006). Since then, the practice of wearing veil in the UK by Muslim women has become debatable in relation to the judgment be hind banning the veil in the economic region. The paper presented here will intend to discuss various aspects related to this issue with due regards to local and global values regarding ‘Hijab’ or ‘Full Face Veil’ along with cultural imperialism and national sovereignty of the UK. The role of media will also be analysed to obtain rational in relation to the debated topic of banning veil in the UK. Local Values vs. Global Values Abraham (2007), in his study adroitly states â€Å"Just as complex discourses have developed around the metaphor of ‘the closet’ and ‘coming out of the closet’, the metaphor of ‘the veil’ and the concept of ‘lifting the veil’ have developed their own political debates†. With due consideration to this explanation of veil, the local values can be recognised in this context. Veil which is also called ‘Naqab’ or ‘Hijab’ originates as an Arabic word that refers to as barrier. Moving further from the lexicon explanation, veil has a broader meaning in the local values of Islam. It largely indicates towards the philosophy of modesty in both men and women (Long, 2009: 93-94). However, in the current day context, the most common metaphor of Hijab is an Islamic woman wearing on veil to cover her head, her face and her body. Furthermore, according to the Islamic values, a veil also tends to provide sexual space to the women in the society indicating that women should keep themselves covered in front of any unknown male figure with whom they were unable to theoretically be engaged, i.e. men who do not relate with their family (Long, 2009: 93-94; Abraham, 2007). Even in the current practices, veil is considered by Muslim women to provide them with space in terms of sovereignty and modesty as well as in terms of sexuality (Gabriel & Hannan, 2011). On the contrary, from a generalised point of view the global values of Islam have often presente d the religion as ‘barbaric’ restricting many natural flows of human life. In many instances, the religious beliefs are also stated to reflect the society to be male dominated. For instance, Islam states that men can have more than one wife provided he is able to render equal love and affection to each (Long, 2009: 92). Similarly, from the global perspective wearing a veil is considered to be a religious belief that creates a social difference between the Muslim women and men of the same as well as other religions. Thus, it is

Answer quesiton - Essay Example By providing a large number of provincial and local executive offices, the mestizos stamped their mark of authority and control over the bicameral form of government in nearly all aspects of the sociological and political history of the Philippines. Further, they consolidated their rights and power by giving administrative rights and powers in the hands of their blood relatives and friends. Their brothers, sisters and other close members were given senior positions in the power blocs, and sons and nephews were vested with junior authority levels. The idea was to ensure total domination of the country in the hands of the mestizos. Thus they avoided democratic forms of sharing power with the elected representatives of the people. The origin of political dynasty rule was enunciated by the earlier Aquinos and Cojuangcos and has since, through the process of descent, passed onto the hands of the present ruler, Corazon Aquino. The absence of democratic process and the rule of dynasties has been one aspect by which the Filipino political scenario differs significantly from that of other South East Asian nations. Yet another aspect is that, unlike other SE Asian nations, which boast of massive bureaucratic style of governing, in Philippines the mestizos are under the administrative control of the Americans, to whom they have pledged support, in return for a bargain to remain in power. There is a minimum number of positions for civil servants and the entire power sharing lies in the hands of the mestizos. There were massive conversions into Christianity and today, nearly 90% of the population is of Christian faith.

International Marketing Essay Example | Topics and Well Written Essays - 1000 words - 2

International Marketing - Essay Example Consumer attitudes consist of three main components, affective, cognitive and behavioral component (Pride et al, 2011). The cognitive component refers to the buyer’s knowledge and information about a product. The affective component is the buyer’s feelings and emotion towards the product. Lastly, the behavioral component consists of the actions of the buyer towards the product. Marketers should seek to identify and understand all this components of the consumer attitudes in order to ensure the success of a product. According to Hassan and Samli (1994), the country of origin effect is defined as the influence that a country’s manufacturer has on the negative or positive judgment of the consumer (Doole & Robin, 2005). There are many methods that can be used by marketers to gauge buyers’ attitudes. One simple method involves questioning the buyers directly. This helps marketers stay informed on the buyers attitudes and identify what the buyer wants exactly. I n 2007, a survey by The Roy Morgan Research reported that 89% of Australian consumers are looking for fresh food that is grown in Australia. 74% of this buyers said that they wanted Australian fresh foods in order to support local businesses and farmers. This research points out that advertising fresh products as Australian-grown is a smart marketing strategy especially when targeting Australian consumers. Therefore, if buyers have a strongly positive attitude towards the country of origin, the marketers should consider playing up the country of origin in its marketing strategy and communications. Another example of this is the 1990s’ Volkswagen’s â€Å"Fahrvehrgnugen† campaign. It asserted the company’s German roots despite the fact that many of the cars that it sold were assembled in low-wage countries such as Mexico. Buyers will, therefore, buy this products since Germany is associated with quality and reliable products. For the same reason, people opt to buy other German made cars such as Bosch and BMW (Chasin & Jaffe, 1979). Likewise, Switzerland is known worldwide for its precision. Watches from Swiss are legendary the world over and for this reason; buyers are even willing to pay a higher price for them (John & Jagdish, 1969). On the other hand, marketers tend to have an uphill task when combating the buyer’s negative perceptions of a product’s Country-of-origin. Russia and South Africa are examples of two countries where marketers experience hardships when marketing their products. Although Russia is well known for producing high quality vodka, many buyers avoid using its products since they still term the country as a communist country (Chasin & Jaffe, 1979). Likewise, South Africa is synonymous with producing very fine wine and at very attractive prices. However, American consumers have been reluctant to buying this product due to their negative perception about the country resulting form the apartheid era al though it has ended (Christopher, 2001). Another country experiencing negative bias, especially in United States, is Vietnam. In countries where negative bias is in existence, marketers should downplay the country of origin especially in packaging and the product’s marketing communications. By doing this, buyers will have less knowledge about the country where the product originated from, and this may result in increased sale of the

Toyota Goes Green Essay Example for Free

Toyota Goes Green Essay With the high costs of fuel and the environment dwindling. Companies have started going green to help reduce cost and find alternative to the natural burdens of the economy by using eco friendly services and products. Car companies like Toyota have gone green to look for another alternative to rising fuel prices and better gas mileage. With their introduction of the Prius, Toyota has become the world’s leading car manufacturer. The Prius also helps out by being environmentally friendly. Hybrid cars like the Prius are designed with an electric motor that is mixed with a gasoline engine that lets drivers get above average gas mileage. â€Å"Existing models get 47 to 60 miles per gallon, depending on where youre driving. Toyota claims you can drive its 2004 Prius from Detroit to Washington on a single tank of gas â€Å"(U. S. A Today, 2007) Toyota has not only made cars to prove that they are going green but they also incorporate ways to save money and save the environment. In an article in the Times magazine it states â€Å"What matters more than one car model,† says the article, â€Å"is the efficiency Toyota brings to all aspects of its business a corporate philosophy that strives to exterminate waste†. Toyota can use a single production line to make several car types, which means it has cut energy use by 30 per cent since 2000. †(Times, Jan 11) Toyota has made a huge financial impact by choosing to design and sell economic friendly products. â€Å"In Toyotas case, green also refers to the color of cash; this month the carmaker announced that between December, 1997, and May, 2007, it sold more than 1 million hybrid cars worldwide. †(Janna, R) The auto industry has made a major impact by producing these hybrids. Toyota is not the only maker of hybrids like the Prius. Honda started the craze by being the first car company to produce the Hybrid vehicle which was called the Honda Insight. The Honda Insight was introduced in 1999 and provided lower gas emissions. Soon Toyota caught on to the craze of hybrid vehicles by making the Prius, the Highlander, and now even the new Camry is a hybrid car. Other car companies like Ford and General Motors have noticed the financial impact and are said to roll out new hybrid vehicles with in the next three years. The environment has been effected tremendously by companies going green. Like the car companies that have gone green other companies have also gone green by trying to find other alternatives for rising fuel costs. It is not only the rising prices of fuel for cars that the economy is focusing on. Energy companies have also joined the cause to go green and fight the rising cost of fuel for electricity. Energy companies are trying to save money while expanding their markets by using less fossil fuel and making products and services that are more economically friendly. â€Å"With energy prices trending higher, the threat to the bottom line continues to grow. That’s made the motivation for conserving fuel more compelling. Some 65 percent of U. S. companies think that escalating energy prices pose a potential roadblock to their companys growth over the next 12 months, according to a survey by PricewaterhouseCoopers in the fourth quarter of 2005. †(MSNBC, 2007) Other companies such as Cargill which is in the global food processing business have started to use their waste into new energy. Using meat scraps they have been able to develop a methane gas that has allowed the company to save money by replacing the high cost of natural gas. Electricity companies have started to use alternatives such as ethanol and wind energy to power the world’s energy. â€Å"U. S. ethanol production hit nearly 4 billion gallons last year, according to the U. S. Energy Information Administration. Nearly 100 ethanol plants are in operation, another 33 are under construction and nine are being expanded, according to the Renewable Fuels Association. â€Å"(MSNBC, 2007) â€Å"Wind energy is also getting a lift. Though it makes up just a half a percent of U. S. energy consumption, its the fastest growing sources of renewable energy in terms of usage and capacity. One big reason is the dramatic cost per kilowatt of producing electricity with wind making it much more competitive with fossil fuels. †(MSNBC, 2007). I can not make any recommendations on what should have been done since I think the rising new technology and the eco friendly products and services are helping cut costs while helping the World clean up the environment. I look forward to the new innovation since these costs are sky rocketing every day. I can only hope that average people like us get the much deserved break that we need.

The Impact Of Deregulation Of Tourism Tourism Essay

The Impact Of Deregulation Of Tourism Tourism Essay National security has always been an issue dating back to as early as when man started organizing himself in society. Tourism has become a major pillar of modern-day economies and cultures. This research examines the impact of tourism deregulation or the simplification of government rules and requirements on tourism to national security. The study will also cover areas on importation of terrorism through tourism; compare tourism crime and other types of crime and finally investigate the changes in crime rate in countries that deregulate tourism. The resident attitudes towards the impacts of deregulation of tourism on national economy will be explored. Questionnaires and simple random sampling can be methods of data collection from the respondents. The data collected will be analyzed using the statistical package for the social sciences. The findings of the study will be presented using pie charts and graphs. Tourism and security are interrelated and inseparable. The security of the tourists is the primary concern of every host government because of it only where they feel safe that they will spend and visit again. The current economic state of most countries has presented a problem because governments have to come up with ways of raising foreign earnings to raise money to service the national debt and keep the economy afloat. One of the solutions has been to simplify government regulations for the tourism industry to attract more traffic. While this has been successful in most countries, recent evidence has raised questions of what effects lower standards for tourists have on the national security of the host country. Tourism is a delicate and dynamic industry. Although tourists have specific countries they want to tour based on experience, recommendation or the spirit of adventure, it is worth noting that some tourists have other agendas. It is impossible to know legitimate tourists from people with hidden agendas such as terrorists without the proper legislation. At the same time tourists are usually free to travel to destinations of their choice avoiding destinations associated with risk. It has been observed that the consequences of disastrous events on tourist destinations are spontaneous and adverse. Some of the insecurity concerns include terrorism of any kind where governments issue travel advisories to their citizens to not visit the affected country. A problem presents itself when the tourism has been imported in the guise of tourism, such that terrorists disguise themselves as normal tourists to enter countries. If stringent laws for immigration were to be put in place as they were befo re, it would be possible to pick the wheat from the chaff. According to (Zurick, 2006) the concept of security has changed through the decades from one of collective security and common defense to embrace notions of common and cooperative security. Despite the damage done to the concept of collective security because of the United States led invasion of Iraq, the development of common security structures through collective as well as multilateral frameworks such as the United Nations is still an important aspect for the expansion of security concerns to cover a nations environment, health and economic security threats. This research also considers that tourism organizations have little influence on peace and security agendas despite the fact that they are important for tourism. This is particularly at the micro-level whereby appropriate tourism development initiatives may serve as a means to prevent potential future conflict over resource and environmental security challenges. 1.2 Safety, security and destination image The world has become a global village and the global relationships have become turbulent, this has therefore called for destination marketing organizations which focus their attention in demonstrating that there is safety for tourists. A tourist perception about a particular destination which may be caused by negative publicity is mostly a question of security and safety. Often, this negative publicity may be unrelated to the reality on the ground but it has more than significant effects on the tourism sector and the economy as a unit. Tourism deregulation impacts on national security can be categorized into positive and negative category based upon economic, socio-cultural, and environmental impacts. According to (Hall, Dallen Duval 2003), tourism is greatly affected by and affects security. The destination a tourist chooses is determined by how safe he or she knows it be, or has been advised is. Changes in the global security affect tourism greatly. The security concerns affect both tourists and the host country that has to face the fact that not all individuals visiting the country have good intentions. Responsible tourists take time to investigate the security situation in the countries they intend to visit. Such responsible tourists should be aware of security risks and take precautions to mitigate such effects or avoid them completely. The September 11th terrorist attacks on the World Trade Towers in the United States of America are an epitome of events that can affect the tourist traffic of any country. Terrorist attacks have an impact on travel, leisure industries and tourist destinations. As a consequence more focus and attention has been directed towards tourism safety and security issues than ever before. The impact of deregulation on tourism laws on national security is a matter that cannot be ignored. Recent research is being focused further on the analysis of not only how travel safety can be promoted but also how security concerns may be incorporated in terms of tourism marketing. The management is also being enhanced to enable the industry become more responsive to chal lenges of security both internal and imported. Countries with unstable security history tend to be paranoid about security but stable and relatively safe countries have been continuously passing regulation that simplifies the process of obtaining tourist visas. The movement of the tourists is also not restricted or monitored. While this markets the country as place where the privacy of visitors is guaranteed and protected, it also attracts people of questionable character. These individuals might commit crime and abscond, or some might use the stability and anonymity to plan attacks on other countries. The latter situation can create a diplomatic spat which, unchecked, could escalate to war. Tourism activities can be affected by either external or internal forces; such forces may include war, terrorism activities, economic recessions, disaster, and financial crisis among others. Nations and cities which have experienced terrorist attacks for example New York and Washington faced profound impact on global travel (Blackford, 2004). The area of security is broad and sensitive and is affected by many things. The relationship between deregulation of tourism and national security can be explored in different perspectives. For example, in examining this relationship the research will look at whether the deregulation of air transport has influenced national security and the tourist destination countries in different nations. Terrorism will also be examined to investigate whether it can be imported in the guise of tourism. It will further examine the impact of deregulation on capacity as well as fares. The study also attempts to determine the impact deregulation has caused on marketing of tourist destinations and attractions. Finally, the research will investigate the impacts of tourism deregulation on transport at the destination areas. The research will also compare tourism crime and other types of crime (Hall, Dallen Duval 2003). 1.3 Statement of the problem The tourism industry has grown tremendously and thus every country is trying to gain a competitive advantage in order to market tourism adequately. This has lead to deregulation of tourism to assist raise tourist traffic. This research will seek to identify these impacts in a wider perspective with respect to crimes related to tourism and also seek to explore the rate of crime in countries that deregulate tourism. With globalization becoming embraced internationally the need for national security has been an issue of concern not only in tourism but in other areas as well. This concern is fundamental if nations are to enjoy and promote tourism while protecting the national security by preventing tourism crime, terrorism and other threats to a nations security that could be as a result of tourism deregulation. Research and experience have evidenced that tourism is a crucial factor that can contribute greatly to the development of a nations economy. It is therefore worth noting that tourism is directly associated and related with the cultural, economic as well as the intellectual potential of any nation. Currently available statistical data indicates that tourism is a leading profit earner in most developing industries in the world and thus the need to protect and uplift it as while not compromising as the national security of a country. It is expected that in the early 21st century the number of tourists will increase dramatically and consequently the revenues from tourism will increase considerably. The evident threats to national security are not something any country passing legislation to deregulate the market can ignore. The purpose of this research is to identify this threats and the correlation it has with deregulating the tourism sector. 1.4 Research objectives This study will be focus on achieving the following objectives: 1. To investigate whether terrorism can be imported in the guise of tourism. 2. To investigate whether countries that deregulate tourism experience high crime rate. 3. To investigate the relationship and compare tourism crime and other types of crime. 4. To identify the impacts of airlines deregulation in international areas with respect to tourism. CHAPTER TWO LITERATURE REVIEW 2.0 Introduction According to the World Trade Organization (WTO), tourism is one of the top five foreign exchange earners in approximately 83% of countries and the main foreign exchange earner for at least 38% of countries globally. In most of these countries foreign exchange earnings are usually used to purchase imports and augment reserves. They generate income in the particular country and can stimulate consumer spending and investment in other sectors of the economy. Tourism provides an ideal situation where there is little need to compensate from outside because it grows the local industries and resources. It has ripple effect on the rest of the economy and any country that realizes this need to come up with innovative ways to encourage tourists to visit the country. Some tourists are turned away by stringent laws of immigration or stay and it has become the norm for most countries to deregulate the market. Tourism is an exciting and fascinating industry. The industrys contribution to the national economy is significant. The major threats to this lucrative industry are socioeconomic problems related to increased level of crime rates and the depletion of resources or sites and events that attract tourists. Similarly, due to the current rise in terrorist activity, it has become a major concern for the natives of the countries being toured. According to Williams (1997) crime is a common social issue which threatens the safety of the people, property, their sense of well being, and also causes entropy to the social order. Crime also reduces peoples quality of life because they are not psychologically at peace and are therefore not able to work as well or as much as they potentially can.(Cracraft, 2000). In all countries of the world associated with popular destinations, crime has been a major threat to the stability of the economy. In a Newsweek research conducted by Zakaria (2002) tourism safety and security matters raised by allowing tourists in is a major headache for any government. It is evident that crime against tourists or associated with tourism is considerably high in tourist destinations. This research therefore investigates the extent to which crime has an impact in a nations security. It is of importance to analyze the impact of passing legislation that lowers the bar for tourists and whether it has become an avenue for crme and threats to national security. 2.1 Impacts of airline deregulation According to (Fallon, 2002), nations globally have realized that liberal aviation agreements have significant impact tourism amongst signatory parties. Recently, there has been deregulation of airlines leading to the growth of low-cost carriers and overcapacity in airline industry to bolster tourist numbers. Further deregulation of international air travel has seen the tourism industry grow significantly as simplified requirements to visit countries are major attraction for potential tourists. In addition, governments are encouraging movements towards agreements with country blocks or many nations rather than individual nations to create open skies in different geographic regions. The result of this is that people are able to move across borders with minimal or no paperwork. For nations to ensure the sustained growth and success of the international airline industry it has become important to adopt aviation policies which are conducive to open skies agreements. This has liberalized air travel beyond existing restraining bilateral among nations. This has a significant impact on tourism as well as other industries, as this facilitates the movement of people around the world. For example the signing of the open skies agreement between the United States and the Philippines deregulated tourism rules. While this is a way of growing the economy, its potential effects on national security are far-reaching. The wanton and indiscriminate hosting of people without adequate paperwork carries with it the risk of encouraging criminal activates. 2.2 Socio-cultural impacts of tourism deregulation on national security According to (Blackford, 2002) it is a fact that tourism has a big impact on the economy of a nation, its cultures as well as the ecosystems. Despite this it is one of the least regulated industries in globally. This has opened up destination countries further to the influx of foreign earnings and capital. This trend of deregulation favors major international hotel chains and tour operators while at the same time providing the residents of the country to earn from the resources, whether man-made or natural. Tourism has long been viewed as the reason for the spread of the global mentality. Cultures and social practices are imported as locals learn from visitors. The lack of adequate background checks on tourists, while offering an ideal protection of the visitors privacy poses a problem. The host country is exposed to the risk of allowing individuals of questionable character into the country. Interaction of these individuals with the locals might do more harm than good. The possible causes of some of the security situations include crime related incidents, terrorism, war, and political unrest or instability. The crime related security incidents may be in different forms such as theft, robbery, rape, murder, piracy and kidnapping. Local residents may commit crimes against residents, tourists against locals, tourist against other tourists, or may take other forms such as organized crimes against tourism enterprises. A specific environmental issue relates to the increased number of planes traversing the skies has led to greenhouse warming. Airplane contrails generate cirrus clouds, which reflect the suns rays and warm the atmosphere (Zakaria, 2007). As this is mostly the result of new fuel-efficient aircraft, which produce less heat and a cooler mixture of exhaust air conducive to contrail formation, governments should consider the environmental impact of more commercial aircraft in the transatlantic market. This rise is directly proportional to tourist traffic because airlines will tend to increase flights to popular destinations so as to increase their turnover. 2.3 Deregulation of immigration and tourism laws. It is prudent to note that this research does not in any way imply that attempts to deregulate the market are inn-informed. On the contrary, liberalizing the industry is a crucial step toward achieving the vision of a global village vision and making the world a better place. However, to deregulate without adequately researching on the effects and impacts on national security is ill-advised. It is no secret that every country has enemies or people who would want to cause harm to it. While most of these groups or individuals might not make their intentions known, the methods they use to deliver the punch are criminal at the least. The template is to exploit the weaknesses in the countrys laws and find the opportune moment to strike and send the chilling message. Giving visas to all and sundry without first checking their backgrounds or requiring adequate and authentic proof of identification might be good for trade, but it is not the least conducive for the security of all affected. Tourists are not required to give detailed schedules of their stays in the countrys they visit and this is the perfect recipe for clandestine operations and activates. 2.4 Importation of terrorism through the guise of tourism According to Cracraft (1986) tourism is an activity that is sensitive and a nation will react rapidly to crime. Acts of terrorism are always a drawback to tourist destinations because it is followed by negative publicity and a host of travel advisories. This is because terrorism acts often indicate inadequacy of security and safety controls. Recent happenings have shown a disturbing trend where terrorists sneak into countries disguised as terrorists, leave among the locals as they plan their crimes. This worrying trend has created a situation of suspicion of people from certain places perceived to breed terrorists such as Middle East. This blanket stigmatization and the blanket security regulations that follow are saddening. The security concerns and weaknesses exposed can be pre-empted by having adequate laws that tend to pick the wheat from the chaff, instead of being left behind to sort the debris. 2.5The difference between tourism crime and other types of crime The growth of tourism has always been associated with increases in the level of certain types of crime (Goliath, 2004). The growth of tourism can also be associated with modernization and development which is a source of social instability which leads to criminal behavior. In addition, tourism crimes are often highly publicized, and the subsequent media publicity is a dent on the countrys image. Another consideration is the fact that tourism growth is mostly accompanied by growth in the resident population. It is important to distinguish between criminal acts directed towards the tourists and those committed by the tourists there are many factors that make tourists attractive as targets of crime which include. While crime is primarily an illegal attempt to earn a living, tourism crime is mostly premeditated and about more than just earning a days meal. It is about achieving a personal, social, religious or economic obligation either to oneself of to a group. As countries continue to pass laws that simplify the entry and stay of tourists without taking into account the dynamic nature of the human being, it becomes impossible to shield against crimes related to tourists. Most of the tourists may be usually highly noticeable because of their race, clothing, speech, and even the tendency to carry valuable items such as cameras, backpacks which attract therein criminals. It is often perceived that tourists are wealthy people and are more likely to be in possession of valuable items. Tourists are mostly accompanied by tour guides and at times they may be strangers. At times in the destination few people may be aware of their specific activity pattern. For example the murder of Meredith Kerche in Perugia, Italy has had huge media attention in the United Kingdom. In addition, issues such as drug and tourism, sex tourism as well as other related crime and social disorder among holidaymakers. The high rate of exposure of tourists as targets to criminal activity in some destinations is illustrated by the findings that have seen tourists being stolen of their belongings or property (Schollmeyer, 2003).This social wrongs impact negatively on the national security because negative social behavior such as drug use and sex trade are primary causes of crime. It has also been observed that criminal activities can as well be committed by the tourists themselves, either against the locals or other tourists. Where certain forms of tourism either foster or entail criminal activities, it is the tourist who is usually seen as the lead player in initiating or engaging in some kind of illegal activity-. The most, obvious example invokes forms of tourism, such as those involving certain types of related activity, which are defined as illegal by destination authorities. While tourism activity may be not completely illegal but a strong criminal association may exist. The best example of this indirect relationship is gambling, given the involvement of organized crime cartels in casino businesses. The influx in tourists to these places might raise the economic might of criminals, emboldening them and causing a general rise in the crime rate of the country. Finally, there are those tourist activities that can degenerate into criminal behavior because o f the presence of alcohol, drugs, arguments or stereotypes 2.6 Crime rate in countries that deregulate tourism It is evident that there is high crime rate in countries that deregulate tourism, for example sex tourism industry has increased all over South East of Asia and Burma (Kristiansen Trion, 2005) and the crime rates in South Africa during high tourism seasons is evident. In these regions tourists are highly involved in criminal activities and are often associated with several kinds of human rights abuses, and the spread of HIV/AIDS. For example women and juveniles are often coerced to engage in the sex trade against their will. While these crimes are abetted by locals, it is the presence of tourists with ill-intentions that causes the rise. As observed earlier the impacts of crime on the destination are diverse. Some cases involve crimes related to drug use, whereby the destinations image becomes blotted resulting in significant decline in tourist demand. On the other hand, theft may occur at tourist destinations where the tourists are at the wrong place at the wrong time. In addition, tourists may contribute to this by engaging in illegal activates or getting involved with criminals. (Magenta , 2009, pp56). CHAPTER THREE RESEARCH METHODOLOGY 3.1 Introduction In order to achieve the research objectives a multi-method approach will be adopted, by use of both qualitative and quantitative data collection methods. Quantitative methods will focus on providing a broad statistical measure of the nature, extent and impact of deregulation of tourism on national security using a reasonable sample size. In depth and comprehensive qualitative information will be collected on the impacts of deregulation of security on national security, importation of crime through tourism, comparison between tourism crime and other types of crime. The research will employ questionnaires to collect data from the respondents as one of the data collection tools. Interviews schedules will also be applied to interview the randomly selected sample population. This chapter presents a description of the procedures and methods that the researcher will use in order to obtain the required data needed for the study. It comprises of research design, data collection instruments, the target population, the sampling strategy, and data analysis methods. 3.2 Research design The researcher will employ quantitative research method. The quantitative research design to be used will be a causal comparative design. The causal comparative design will allow the researcher to collect one or more information from one participant. A casual comparative research allows researcher to investigate the possibility of a causal relationship among variables that cannot be manipulated. This research design will be used to establish the factors that influence employee training. 3.3 Target population The target population will involve the immigration departments, tourists and locals of the target country. 3.4 Sampling strategy Simple random sampling techniques will be the data collection methods from the various departments. The employees will be randomly selected from each department to yield the total sample population. Purposive sampling will be used to select employees who are trained. Purposive sampling is a sampling technique that allows a researcher to use cases that have the required information with respect to the objectives of the study. 3.5 Data collection tools and instruments. The researcher intends to use questionnaires in this study. This is to provide high accuracy and validity of the study. The questionnaire is a convenient tool especially where there are a large number of subjects to be handled. The questionnaire facilitates easy and quick derivation of information within a short time. The information obtained will enable to investigate the impacts of deregulation of tourism on the national security. 3.6.1. T-test T-test will be used to test whether there are significant differences between two mean derived from the samples of groups at a specified probability level. 3.6.2 Chi-square Chi-square is a statistical technique which attempts to establish the relationship between two variables both of which are categorical in nature. The technique compares the proportion observed in each category with what would be expected under the assumptions of independence between the two variables. CHAPTER FOUR DISSECTION 4.1 Data analysis The researcher will establish whether all questionnaires are all completed. Data collected from open ended and closed questions will be coded for analysis purpose. Descriptive and inferential statistics will be used in data analysis. The data will be analyzed using the statistical package for the social sciences (SPSS). The descriptive statistics which will be used in analysis includes means, frequencies, percentages and standard deviation. The inferential statistics that will be used in data analysis will be chi-square and T-test for independent samples. 4.2 Expected results It is expected that this research will yield results that show an upsurge in crime levels in countries that have liberalized tourism industry. In some countries with more stringent practices and therefore less tourism traffic, it is obvious that the crimes related with tourism will be less. This is a wake-up call to all legislators to take necessary precaution when passing laws that deregulate the market and give the players a free-hand to do what they want. National security should take priority over economic gain.

Bike Helmets :: essays research papers

Arizona needs a law requiring adult bicycle riders to wear a helmet! Have you ever known somebody who was injured in a car accident? What do you think his attitude about seat belts was after they saved his life? If you knew that a seat belt would save your life, you would buckle up! It took years of legislation and public awareness campaigns to make seat belt use mandatory. Now a new topic regarding public safety is coming to light: people are dying or becoming seriously injured in seemingly minor accidents on bicycles when the rider's head strikes the concrete. When the head is unprotected "the brain continues to move in a forward motion while the skull stops moving" (Macyko1), causing trauma. What is needed is a way to protect the brain "by absorbing the energy from the impact, buying extra time for the brain to slow down" (Macyko1). Bicycle riders need to wear helmets to protect their brains from injury, yet unfortunately the public is simply not aware of this need and many people will continue to die or be seriously injure d unless something is done. Bicycle helmets save lives and should be required by Arizona State law for riders of all ages. Opponents feel that bicycle helmet laws are too strict and are misdirected. Principally, they feel that helmet laws do not prevent accidents and point out the fact that "motor vehicles are involved in 90-92% of bicyclist deaths" (BHSI/Compendium 4). Creating awareness among drivers by lowering their speeds would create a safer cycling environment. Furthermore, opponents of helmet laws believe that "requiring motorists to wear helmets will save more lives" (Convissor 1) since statistics show the likelihood of fatality while riding in passenger cars is nearly double that of bicycling (Bicycle 15). They are also concerned for the overall popularity of their sport when helmet laws go into effect. After helmet laws went into effect in Australia, "surveys in Sydney found the helmet law reduced cycling by 38%" (Convissor, 1). Another issue is the argument that helmets are inconvenient and uncomfortable. The opponents of helmet laws seem to have a good argument. Helmet use cannot prevent an accident and Department of Transportation statistics indicate seventy five percent of bicycle related deaths are in collisions with motor vehicles (American Academy of Orthopedic Surgeons 2), which implies the real problem is with automobile drivers causing accidents with bikes.
