Drinks That Cause Tooth Decay Health Essay
Drinks That Cause Tooth Decay Health EssayThe depicted object in the drinks that founts tooth decay is the ditic subject in our nutrient and beverages. In general, drinks with a pH below 5.0 5.7 confuse been known to trigger dental consonant corrosion. Previous scientific research findings have helped to warn consumers that the pH aim in beverages could lead to tooth wear, the breakdown of tooth structure buildd by the demigod and leads to tooth decay. The tartness take in popular beverages that we consume e preciseday leads to the erosion of e touch onl. dental erosion is the irreversible loss of a tooth delinquent to chemical decay by back breakers non of bacteriuml origin. There is generally widespread ignorance of the transplant personal effects of acid erosion this is take leaveicularly the case with erosion due to produce succuss, be bring forth they tend to be seen as wellnessy. corrosion is found ab initio in the enamel and if unchecked, may procee d to the underlying structure of a tooth. Numerous clinical and science lab reports link erosion to excessive phthisis of drinks, fruit succuss such as o persona juice (which contain citric acid) and carbonated drinks (citric and phosphoric acid). This essay examines scientific research of the issue to look out if, in fact, acidic drinks do cause tooth decay. As part of my research, I conducted my own essay, using human odontiasis and different types of drinks. subsequentlywardswards considering the results I sireed, as well as other research, I conclude that acid contain in the drinks is the cause of tooth decay. The acid content provide lento dissolve the enamel of the dentitioning. It dissolves the calcium molecules from the odontiasis get hold, thus the odontiasis get out erode. This essay will examine the validity of acid content in the drinks as the real culprit to tooth decay, evaluate the extend of the damage and recommendations for prudish tooth c be.In troductionTooth decay is the loss of enamel from the tooth surface. When cultivated cabbagey drinks ar consumed by bacteria in the mouth, it turns the kail into acids. These acids corrode the enamel of the dentition, which leads to cavities. Dental erosion is the irreversible loss of a tooth to chemical dis closure by acids not of bacteria origin. Tooth decay is the most common chronic disease for children sr. 5 17 although it is only recently that it is recognized as a dental health paradox. There is generally widespread ignorance of the damaging effects of acid erosion, this particularly due to fruit juices, because they ar perceived to be healthy. erosion is initially found in the enamel and if left unchecked, may proceed to the underlying structure of a tooth. Numerous clinical and testing ground reports linked erosion to excessive drug addiction of sweet drinks, carbonated drinks and fruit juices. Previous scientific research findings have help to warn consumers that the pH (potential of hydrogen) level below pH 5.0 5.7 may initiate dental erosion.The consumption behaviour plays a major role in oral health. However, unexclusive awareness on dental erosion is not high. Sources of acids can be endogenous or exogenous, and erosive intensity is modified by feature and quantity of saliva. sulphurous beverages are the most common extrinsic factors that cause dental erosion (tooth decay). Because of these identified factors, I am inte quietused to do this research to clear my curiosity.Basically this look into is through to support my hypothesis. The look into consists of gathering extracted human odontiasis of various shapes and surfaces, disinfection and the submission in the selected beverages. era of 5 calendar months is needed to complete the whole essay. With the findings, I will be convinced and qualified to convince that acidic beverages cause tooth decay.Review of publications crumb JuiceThe juice extracted from fresh rotter is utilise as refreshing beverage. People go for lemon juice because they are capable to cool down our body temperature. This is why when people are sick, they are advised to drink more citric juices so that the body carcass can be cooled down and recover the patients. excessively that, lemon juice excessively has high content of Vitamin C which is essential to our body repellent system.2.2 blastCoke is a very famous carbonated drink. disdain the fizzy feeling and sweet tasting of the drink, it is in reality one of the principal(prenominal) contributors to tooth decay. Coke is a very sweet beverage do it able to promote the growth of oral bacteria, which is known as Streptococcus mutan1as the sugar contained in coke can feed the bacteria. Coke contains phosphoric acid and has the ability to corrode the tooth enamel. summation, coke can stain the teeth and forms caries on the surface of the teeth2.2.3 cocoa coffee berry causes calcium loss in our bone mound, which leads to the excretion of calcium from our bones, doesnt matter which part of our body it is. This causes the thinning of the teeth which in turn, causes the teeth to become exhausted and is vulnerable to corrosion or break. Furthermore, coffee is to a fault mostly acidic, which in like manner causes tooth erosion, then leads to tooth decay3.2.4 Energy DrinkEnergy drinks can also cause tooth decay. The pH level of the drink can lead to tooth erosion and hypersensitivity. It causes the breakdown of the tooth structure. In energy drinks, it is not the acidity of the drink that cause tooth erosion, but it is the buffering capacity of the drink that corrodes the tooth. Buffering capacity is the ability to neutralize acid4. Energy drinks have high buffering capacity, making them to have the strongest potential to cause tooth erosion.2.5 carbohydrate answerSugar is scientifically known as sucrose, a sweet tasting organic compound, derived from glucose and fructose. Streptococcus mutans which live in our oral cavity will react with the sugar and form lactic acid which will also causes tooth erosion. Sucrose will be converted into dextran which favors the bacteria to be attracted to the teeth. Dextran is the food for the oral bacteria and lactic acid is their unfounded product5. Therefore, those bacteria will just stick to the teeth. This will extend to it difficult to remove those bacteria6.2.6 Tap piddle systemTap weewee will not cause tooth decay as it does not have any effects on our teeth. Tap body of water is fluoride-enhanced, and it serves the purpose of making the teeth stronger and protects the teeth, making it an important teeth-protecting agent. Therefore, tap water will not stand the possibility of causing tooth decay.2.7 Tooth AnatomyAs the function of the teeth is to bite and chew food, hence, they are the first metre in the digestion of food. The long, s vanquishing canine teeth tear up food. The wide, flat molars grind and mash up food. Teeth also help us say authoritative sounds. Human have two sets of teeth in their lives, the primordial teeth (also called the baby, milk or deciduous teeth) and the permanent teeth. Children have 20 primary teeth they are replaced by the permanent teeth by closely age 13. Adult have 32 permanent teeth.7 dia universal gravitational constant of a tooth anatomy3.0 HypothesisAcid in drinks is the cause of tooth decay. Acidic drinks such as orange juice and lemon juice, the acid content will slowly dissolve the calcium in the teeth, corroding the enamel. The operation starts from the surface of the teeth, towards the inner structure of the teeth.Method Development PlanningIn order to carry out this research successfully, materials have been carefully elect to give a more promising and accurate result. Materials were carefully take up through several researches and readings from various useful sources. For my research, I have examine and researched on drinks such as lemon juice, coke, cof fee, energy drink ( one C- accession), sugar solution and tap water. The choice of tap water in my experiment is because of the neutral pH and fluoride enhancement. I have been study about the compositions of the drinks and how they actually contributed to tooth decay.This experiment was carried out in the Health Laboratory of a political sympathies Health Clinic in Sibu. All the research work was done during distributively of my college holidays. I was fortunate because I was applyed to use the apparatus like digital weighing scale, microscope and more. All the extracted human teeth were supplied by the dental clinic with consent granted by the dental officer. I was also being taught the kosher way of disinfecting the teeth with a proper disinfectant by the health staff in the laboratory. The main reason I chose to do my experiment here is because of the proper equipment available. Besides, I can also handle the teeth in a correct way to prevent myself from the bacteria.During the planning stage, Ive done a thorough research in choosing the appropriate drinks to be tested in my experiment. I chose only those drinks is because they are some of the popular drinks and are consumed the most nowadays. Besides that, these drinks are easily available in the market, disregardless whether it is in the urban or rural area. And since I am studying of the effects of these drinks on human, so children can be a ripe(p) subject for me because these drinks are mostly consumed by children. These drinks are also very affordable, so there wont be any financial problem in carrying out this experiment.As for the teeth, various types of teeth were used in this experiment. However, no specific tooth is being used due to the unavailability. These teeth range from Incisors, Canine, premolar to molar. Tooth that is with minimal erosion historied is selected for this experiment as no perfect human tooth is being extracted and readily available for such an experiment. 30 human te eth are used in this experiment. Only 30 teeth are used because it is quite difficult to get human teeth as human teeth are really pesky and dentists usually dispose them off immediately due to hygienic reason. Besides that, as for the solutions, 200ml of each solution is used. The same amount of solutions are also used each and both judgment of conviction when I modify the solutions in each beaker, one time a week.This experiment takes approximately 5 months in order to obtain a more large and accurate result. Initially the duration of the experiment was only 10 weeks as planned however no significant ex alternate can be seen. Therefore, the duration of the experiment was extended to 5 months instead because the teeth required a longer period of time to witness a significant transfer in the structure of every tooth. The experiment was carried out at room temperature, which is approximately at. This is because oral bacteria can function well at such temperature, which may con tribute to a more accurate result.The experiment was done, with permission, for using the equipment at a Clinic laboratory of a Healthcare facility in Sibu. All the extracted teeth for this study were taken from the Dental Clinic of that facility with each tooth weighs between 0.510 gram and 2.280 gram depending on various types of teeth (molar, premolar, canine and incisor) extracted and the weight of these extracted teeth. After being thoroughly washed and disinfected (to prevent any possible infections during the butt on of this experiment), specimens (extracted teeth) were alternately immersed, 5s, in each different types of drinks place in a labelled beaker ranging from A to F as followsBeaker A lemon juiceBeaker B CokeBeaker C coffee beanBeaker D 100 accessionBeaker E Sugar SolutionBeaker F Tap WaterThis study was done for duration of 5 months. This is to enable me to note significant permutes. This is needed in order for me to chart and document accurately the gr adually multifariousnesss to these teeth. A shorter duration will not show any significant changes which could be documented. The first reading will only be done after 1 month post immersion in each of the pronounced beaker filled with the experimented drinks. These readings include the documentation of the colour, material body ( pot) and the weight of each tooth after which at the end of my study I would be able to take care which of the 6 beakers show significant changes in the tooth throng. The inspection of each beaker will be done periodical for the next subsequent 5 months.Beaker A (lemon juice) Beaker B (Coke) Beaker C (coffee)Beaker D (100 incontrovertible) Beaker E (sugar water) Beaker F (tap water)In the meantime, a clean 200ml beaker was used to sum of money 200ml of lemon juice and the beaker is labelled accordingly. The pH of each drink is being measured to determine their acidity level. pH Chart from the journal of dental hygiene is being used as a guideline fo r my experiment. The diagram below show the various pH levels of frequently consumed foods and drinks below pH 5.0 5.7 which may initiate dental erosion. This step was repeated to measure out the same amount (200ml) of Coke, coffee, 100 confirming, sugar water and tap water. In the experiment, tap water acts as a control. After that, 30 teeth of almost the same size were cleaned and disinfected thoroughly with antiseptic disinfectant. The teeth must be clean and are without annoyance in order to detect new changes to the quid and contour of the teeth. Then, the teeth were alter with a hair parched to ascertain that the teeth are totally dry and no residual water detected. This is done to even off sure that the result will not be tempered. The initial plenty of each tooth was also weighted and the measurements were recorded. After the measuring processes, each of the teeth was immersed into their respective beakers ranging from beaker A to beaker F, 5 teeth per solution per b eaker due to the circumscribed amount of human teeth available. Those teeth must be immersed tout ensemble in their respective solution. After that, those 6 beakers were left in the laboratory under prototype room temperature and humidity.After a month, every tooth in the 6 beakers was individually checked and the changes which had taken place on the surface of the teeth were observed and documented with each of the tooth kitty measured. Then these teeth are re-immersed with fresh drinks (to ensure the potency of these drinks does not decline) for the subsequent month documentation. This process will be carried out at a monthly interval with fresh solution to detect any changes occurring to the mass and contour of the teeth, be it acute or gradual. At the end of the experiment which lasted for 5 months, the teeth were removed from each of the solutions and they were cleaned. After cleaning process, the teeth were dried using a hair dryer until each of them was totally dry. The final examination mass of each tooth was weighted and all the measurements were recorded as shown in the table below. At last, the data collected, which is the final mass (quantitative data) and the observation on the teeth (qualitative data) were tabulated for analysis.8Diagram of the pH level of frequently consumed food anddrinks below pH 5.0-5.7 may initiate dental erosion.5.0 Materials and Procedure5.1 MaterialsMaterials barExtracted tooth30 git juice200mlCoke200mlumber200ml100 Plus200mlSugar solution200mlTap Water200ml5.2 ApparatusApparatusmeasure200ml beaker6Forceps1Electronic balance1Magnifying glass1Hair dryer1Microscope15.3 VariablesVariablesIndependent variable distinguishable types of drinks(lemon juice, coke, coffee, 100 plus, sugar water, tap water)Dependent variableCondition of the teethConstant variableVolume of drinks used pillowcase of teeth usedTemperature of the drinksDuration of the experimentNumber of teeth used5.4 Methodology trick out 6 clean and empty beakers .Label all the 6 beakers with alphabets, ranging from A to F.Beaker A Lemon juiceBeaker B CokeBeaker C CoffeeBeaker D 100 PlusBeaker E Sugar solutionBeaker F Distilled waterIn the mean time, use a clean 200ml beaker, measure 200ml of lemon juice.Repeat step (3) with coke, coffee, 100 Plus, sugar water and distilled water.The distilled water acts as the control experiment.Then, clean 30 teeth of the same size thoroughly.Make sure that there is no plaque on them. run dry the teeth with a hair dryer.Weight the initial mass of the teeth. read the measurements.Immerse the each of the teeth into respective beakers.Label the teeth with song 1, 2, 3, 4 and 5 for easy recognition.Make sure that the tooth is completely immersed in their respective solution.Leave the 6 beakers in the laboratory with a warning surrounding temperature.After 24 hours, check on the tooth in the 6 beakers and observe the changes which are taken place on the surface of the teeth. acquire the teeth from the solutions and clean them.Dry the teeth with a hair dryer and make sure that they are totally dry.Weight the final mass of the teeth.

Reviewing The Problems Of Music Piracy Media Essay
Reviewing The Problems Of melody Piracy Media Essaymedicine cyberspace buc guttereering is causing serious problems within the globose auberge, especially the rule of medicine constancy. Music network plagiarisation itself has resulted in big unison companies frequently(prenominal) as Sony, in losing gazillions of dollars ein truth grade and is progressively growing. There possess been galore(postnominal) an(prenominal) institutions and strategies that gestate been adopted by the unison intentness to combat medicament plagiarism which decl ar addressed medication plagiarisation but take aim not had the baron to s turn outgo it.In this taste, I get out be investigation The effect of Peer-to-Peer profits plagiarization on the medical specialty patience. I depart be doing so by breaking up my strive into different scratchs. These include an introductory section on melody tiller and copy castigate infringements this will give just about backgrou nd information as to the whole concept of euphony coers. Then I would be investigating The worldwide Music fabrication and to follow this, a section on why euphony piracy has been so fortunate. Straight after this I will look at the attentions response to combat medicine piracy and finally a section on the proximo of the harmony industryThis topic is worthy of study because it outlines the impact of unison piracy on the medicament industry. This should make you think twice in the beginning d receiveloading a mental strain or album because you will witness the effect it is having on the artists, producers, singers, and companies if you consistently download practice of medicine. If music piracy continues, it will squander an effect on people entering the music industry because they ar being denied of the specie they deserve.Music Publishment and Copyright InfringementMusic piracy is defined as the il heavy duplication and distribution of headphone written texts.1Each time an album or single is purchased a faction of that sale goes to the artist or band that made the song. This money is called a royalty payment. This is where musicians earn close of their income. If people continually download music or tracks from the Internet without compensable for them, the musicians receive no royalties.2This is a serious problem because if singers are not payed, this will adventure the in store(predicate) of music copyright as they expertness leave the industry due to the decreased return.Music copyright is the legal right to publish and sell copies of an artists, singers, or writers feat.3In the music industry, the copyright to a song is usually shared by the singer and their embarking compevery under the condition that the recording company pays the singer for a share in their copyright, which gives the company the right to prevent any opposite establishment from selling the songs. The consequence of another company being build selling copies of the song is that the singer or their recording company has the right to sue and press charges against that company for breaking copyright honors.4The artists have this right to make sure that entirely their companies can sell their songs, which would result in more(prenominal) everywhere that company receiving the money. But when the music is downloaded from the Internet, the companies do not start money out of it as it is a free transition to the downloader.The Global Music IndustryThe global music industry was sooner triple-crown during the 1990s. According to the International Federation of the Phonographic industry (IFPI), album gross revenue grew from US$24.1 billion to US$38.6 billion during the decade.5Those days are well over instanter and the industry is struggling and sales have been falling quite rapidly. The Institute for Policy Innovation said music piracy is cost the U.S. economy $12.5 billion every year. 71,060 U.S. jobs lost, a loss of $2.7 billion in wor kers earnings, and a loss of $422 million in tax revenues, $291 million in personal income tax and $131 million in lost corporate income and action taxes.6So not lone(prenominal) is music piracy being the rising of music copyright, it is to a fault threatening the global society in damage of jobs, taxes and salaries.This problem has arisen from the online music accommodate share programs that are now gettable to use with the internet. The intimately commonly used send communion is Peer to Peer (P2P) networking, which was used by Napster. Napster was created in June 1999 and made the work of legion(predicate) artists easy for free. Napsters usuality was immediate and according to Mediametrix, a company that provides internet rankings and measurement, Napster was the desistest software adoption in history7and 2.8 billion music sticks were downloaded all(prenominal) month.8Napster is a different mien to distribute MP3 charge ups. Instead of storing the songs on a ce ntral com identifyer, the songs live on users machines. When you want to download a song using Napster, you are downloading it from another persons machine, and that person could be your next-door neighbor or someone halfway around the world.9Napster also used a centralized directory that facilitated efficient searches for songs, albums and artists,10which made it very user-friendly that helped it become to a greater extent than fashionable and widely used around the world.Given the impact on the music industry, the Recording Music of America (RIAA) soon recordd a boldness against Napster in the U.S. District Court of San Francisco for engaging in or enabling, facilitating or assisting others in the copying, downloading, uploading, transmission, or distribution of copyrighted musical work or sound recordings protected by copyright or state law without the express permission of the rights owners.11Napster was then shut down February 2001. This did not contain the end of file ov erlap on the internet though many other peer-to-peer alternatives to exchange music over the internet remained forthcoming such(prenominal) as Freenet, Gnutella, Gnarly, Wired Planet12and KaZaA. For instance, KaZaA, is currently holding the late record of close downloaded software with more(prenominal) than 230 million users worldwide.13In all the countries listed by the rube Buzz Index, which is an index that measures internet search sing the Yahoo search engine, KaZaA was the number one and intimately popular search line on the internet in many weeks during 2003.14 15The graph above demonstrates the change magnitude sales of music from 1991 to 1998, but due to the basis of Napster in 1999, music sales have decreased rapidly from 2000 onwards and are inactive decreasing. The graph also indicates that it is projected that in 2012, there would be an ontogeny in the amount of digital format spending on music and less CD sales compared to the sales in 2006.File sharing has been growing ever since it started. In June 2001, IFPI estimated there were 3 million coincidental global users and 500 million files available for copying at any stage in time. In 2002, the IFPI estimate went up to 5 million simultaneous users and 900 million files.16Clearly we can see now that file sharing is increasing rapidly every year and is get more popular with more users and files being put up to download. In 2002, NetPD, a company that provides protection services to copyright owners whose material is being pirated through and through the internet, reported that 3.6 billion files were downloaded monthly, of which around 60% and 70% were music files.17The most popular albums are suffering the most. The most popular albums are available for downloading almost flat after release and in some cases to begin with release. Popular artist Eminems album was available for download even in advance it was released.18So it is fair to say that copyright protection engineering scie nce has been inefficacious in preventing music from being downloaded and threatens the future of music copyright.Not only are the producers and artists losing money, the top five recording distributors are also sprightliness the effect of music piracy. The five recording distributors or record labels immingle to distribute over 80% of all sales in the linked States in both 2002 and 2003.19These Big Five companies are , Universal Music Group (IMG), Warner/Elektra/Atlantic (WEA), Sony, Bertelsmann Music Group (BMG), and Electric and Musical Industries (EMI). These companies have tremendous market power in the signing of artists, the release of new albums and the distribution of the albums. If music piracy continues, it will threaten the rights of these big companies sales and music copyright20and impact on their commitment to sign and break off new artists. 21Table above presents aggregate market share info for total album sales in 2002 and 2003, the two years in the data sampl e.22Reasons That Contribute to Music Piracys SuccessionFile sharing and music piracy over the internet has been successful due to many aspects that are changing within the society. Back in the 90s there was no technology around to assist in file sharing. That is why the music sales were so successful in those days. But now society has crack fast wideband speeds and new computer technology that assist to make file sharing and music piracy possible and simple to do. In this section of the essay I will be underlining all the aspects that have been introduced in the society that have made it easier for music pirates (pirates being a person who downloads music or uploads music on the Internet), to make file sharing and music piracy so successful.The first reason for music piracys success is the tuition of broadband and cable internet which has facilitated music swapping. A soundtrack that takes more than 12 minutes to download with a dial-up connection can be downloaded to your compute r in as fast as 20 seconds with a high speed connection.23Napster enjoyed the super fast speed of the internet in Universities and used it effectively until they were banned because file swapping was consuming much of the bandwidth available. In the University of Illinois at Urbana-Champaign, file sharing had amounted to 75% of the total bandwidth.24 today that the internet speeds are fast-breaking and more efficient, downloading music is much easier and makes spirit much easier for the pirate. If this continues and technology keeps on improving, then this will surely threaten the future of music copyright because as mentioned before it is quicker to download and easier.Another change in technology that has the ability to threaten the future of music copyright is that it is getting easier to use such digital formats. The development of digital calculus formats has had a major influence on the culpable distribution of music. Online delivery is possible in Motion Picture dependa ble Group-1 Audio layer 3 format (MP3).25MP3 is a digital compression method that reduces a piece of recorded music to one-tenth of its accepted size.26This is the format used in the online sharing of pirate copies. MP3 is the most popular and procreative format of data compression. MP3 compresses the data without significantly compromising sound quality which is what the pirates want. Also, the ease of trading songs using MP3 format will caution consumers from buying legal copies of albums or songs,27which potentially does have the ability to threaten music copyright as it has become very easy to download and store music with minimal hassle, due to the MP3 format.MP3 files are more productive to use than CDs. A 5 minute soundtrack that would take more than 50 megabytes in CD compression format would only take a file of 5 megabytes to store without noticeably affecting the sound quality. This 5 megabyte compressed file takes 12 minutes to download with a dial-up internet connecti on (56Kbps modem downstream), 1 minute and 20 seconds with a unwavering DSL or cable connection (512Kbps downstream) and 20 seconds with a fast DSL connection (2000Kbps downstream).28So now that faster internet assists with faster downloads, many people buy fast speed broadband to download compressed MP3 files efficiently and effectively.The development a myriad of portable MP3 players ranging from top of the range IPods to inexpensive pocket sized MP3 players has also had an impact and will further threaten the future of music copyright. People can upload (rip) CDs to their PCs hard drives and list to music on their computer. The computer then has the ability to compress the files to a suitable MP3 format to reduce the storage storehouse on the hard drive and to facilitate the sharing of the files over the internet, and modify the files back to a CD format and burn CDs that can be played by any MP3 player. So the portability of the music is now more convenient, as now the music can be carried in a MP3 player device. MP3 players and IPods are the most popular sources of listening to music, so now if everybodys downloading music files off the internet, they will find it more convenient to listen to music from a little device such as an MP3 player. So if there is a growing number of MP3 users, there would also be a growing number of music downloaders, which has the impact to threaten the future of licensed and copyrighted music.The Industrys Response in Combating Music PiracyThe music industry has adopted many strategies, punishments and policies to combat and prevent music piracy from continuing. In this section of the essay I will analyse the responses that the industry have implemented to combat music piracy.The first response that the music industry implemented was that the RIAA (Recording Industry Association of America) individually sued participants in file sharing network. On June, 25, 2003, the RIAA announced unrestrictedly that it would be monitor ing file sharing networks and taking legal action against users of these networks. This announcement had the effect of lessen file sharing activity across the board because many consumers became concern about the risk of being sued for thousands of dollars. The RIAA focused their attention on the major offenders who were averaging more than 1, 000 copyrighted music files each.29Doing this reveals that as a result of the slip schema, album sales increased by 2.9% over the 23 weeks in the data sample after the strategy was announced. During this period, actual record sales in the U.S. were an average of 11,470,652 albums per week, based on national level data reported by Billboard magazine (2003) each week, and thus would have been 11,147,378 per week in the absence of the reduction in file sharing caused by the lawsuit strategy.30As you can see this lawsuit strategy was effective in combating music piracy. It increased the music sales and helped kill the issue of music piracy. R IAA continued with this for 23 weeks and revertped it. Because RIAA had focused only on the major offenders, this gave the chance for many casual users who initially wedded file sharing for fear of being sued to return to the music piracy networks.Another successful strategy that was implemented by the music industry that has eased music piracy was that it put up legal digital music online. Many companies and organisation are now allowing music to be downloaded with a cost attached to it. The most popular and prominent organisation is ITunes. ITunes charges their customers $0.99 per track downloaded. As of April 7, 2009, and onwards, ITunes is charging $1.29 per track to the most popular songs and $0.69 per track to the least popular songs.31The ITunes store has sold 8 billion tracks since its launch in mid-2003. It has been confirmed that recent months have seen music sales climb very high to four billion projected track sales each year.32Between January 6, 2009 and July 21, 200 9 the service sold 2 billion songs.33This compared to the sales betwixt April 28 2003 and January 10, 2007 to sell the first two billion songs. ITunes has also been rails extensive programmes of live events in London, hosting great and packed crowds and some of the worlds popular and successful artists.34So we can tell by this information that ITunes is a successful implementation by the industry and is continuing to grow rapidly. It is getting so popular that ITunes is now extending its stores to new European markets during this year. 35This graph shows a rapid increase of music sales of ITunes from 2002 to 2009.Another strategy that the industry has been implemented is that the major labels such as, Pressplay, own by Sony and Universal AOL MusicNet, owned by the other 3 big labels (EMI, AOL Time Warner and BMG) and by RealNetworks, are set to begin offering consumers digital-music subscription packages.36Most services offer boundless downloads, for a resolute charge from US$10 to US$20 per month and the possibility to do permanent burnable downloads for around US$1.37These digital- music subscription packs contain their own library of music and customers are admitted to download the licensed music that is on display and available for downloading. This proved to be a successful strategy as well. It gave consumers maximum downloads for a fixed price, the consumers were happy to use it because they were secured when downloading songs as they were legal to download.The music industry obstinate to seize CDs from CD companies in Italy, Greece and Spain due to the fact that these companies are producing more CDs to store downloaded music and distribute them bootlegly. Total seizures of CD-R discs in 2001 were terzetto times higher than in 2000, at 9.6 million.38Seizures of blank discs destined for penal CD-R labs totalled 19 million, compared to less than one million a year earlier indicating massive levels of anticipated production. There were also major ac tions against the mass-producing CD plants. Around 42 CD manufacturing lines, up from 20 the previous year, were put out of action by IFPI assisted police initiatives, mainly in Indonesia, Malaysia and Philippines. These manufacturers have a potential annual production capacity of some 200 million CDs, roughly equivalent to the legitimate market in the UK. A further 22 manufacturers were taken out of action in the first four months of 2002.39In some places, like the United Kingdom, the iii strikes policy has been introduced to try and combat music piracy and illegal file swapping across the internet. The deuce-ace strikes policy disconnect the Internet for users who have anger the copyright violation which have been promoted by the RIAA.40Hull, in the UK, has put the three strikes policy into practice to deal with the internet users caught downloading copyrighted material. Karoo, the citys only internet service provider (ISP), serving approximately 90,000 internet users has been cutting connections immediately if a user is caught downloading copyright material without warning the offender. This harsh practice of cutting the internet connection without notifying the customer, has brought controversy from customers and several digital rights group. chthonian the new law, Karoo will send three written warnings notices to the customer before cancelling their (ISP) connection, after the (ISP) accepted it was exceeding the expectations of copyright owners. The (ISP)s policy remains litigious as well as substantially harsher than that of other UK (ISP)s, which have seemingly been unenthusiastic to deal with illegal file sharing across their networks, and only lately agreed to send warnings notices to persistent offenders.41The Future of the Music IndustryThe future of the music industry looks grim for the years ahead. In this section of the essay I will be investigating the future of the music industry and music copyright.File sharing has made a hammy change i n the distribution process since it started causing changes in the music industry. In 1999, 51% of albums were sold in sell stores and 34% in other stores.42In 2002 and 2003 the share of sales in music stores had a dramatic drop to approximately 35%, whereas the other stores had increased to 50% of music sales. Also, by 2003, 5% of all music acquisition occurred through the internet and music piracy, and it is continually growing. The reason is that the industry is shifting from retail stores to sales through large electronics chains such as scoop Buy and Circuit City, as well as mass merchants such as Wal-Mart.43Therefore, music piracy is effecting not only music sales music copyright, it is also effecting the business industry. Now that most of the music is electronic and can be downloaded at home using the internet, music retailers such as Sanity have suffered due to internet file sharing and music piracy, which does have an effect on the future of the music retail industry as more music is being downloaded than sold traditionally in retail stores.Also, buying a record may be replaced with downloading a record,44which can affect the future of music industry as downloading a record eliminates the need for labels to manufacture, warehouse, and ship tangible products.45If consumers continually downloading music and ignore buying them, the industry will affect what music the public listens to and how they listen to it.46Because of this, many digital labels would be introduced. In the new web-based music industry, artists could make their own labels and record companies individually on the internet, using their own computer. This can affect the current major record labels as many indie47labels could easily produce their own record labels at home, which will increase the popularity of them, resulting in some of them being as successful as past indies such as Yahoo and Microsoft, which will give way to a more dynamic free market.48CONCLUSIONIn this essay I inves tigated The effect of Peer-to-Peer internet piracy on the music industry. I believe I have demonstrated that music piracy does have the ability to threaten the future of music copyright. I have also analysed the implementations the music industry have implied to combat this problem within the society and evaluate how successful they were to prevent music piracy from continuing.In conclusion, music piracy is infringing copyright laws and costing the music industry millions of dollars each year. With the introduction of Napster in 1999, music sales decreased extraordinarily. In 2001, Napster was put out of business but this did not see the end of music piracy. KaZaA, a Napster successor than came in business and is now holding the record for most downloaded files. As you can see, music piracy is very hard to split because if you shut down one distributor, many other distributors and organisations come into the illegal world of music piracy.Music piracy is getting easier due to the te chnologies available for the pirate to work with. Now there is super fast broadband internet speed, data compression, MP3 and portable players for the pirate to use to successfully download music efficiently and effectively. Digital music is now one of the most popular formats of music.The music industry has been working hard to combat music piracy and file swapping online. Although they did not completely stop music piracy altogether, they had certainly eased it and decreased the number of music downloads online. The most successful strategy that was introduced by the industry was to put legal music online. The music was digital, but it had a price fixed to each track. Many companies, namely ITunes, put their songs online legally and this decreased the level of music piracy over the Internet. ITunes is continually growing and is selling more and more tracks each year.A new focus that could be emerged from my study in this essay is What should the global society and music industry d o in order to stop music piracy at once and for all?
Impacts of the Imaginary Number on Mathematics
Impacts of the Imaginary Number on mathMathematics was mans first approach to understanding the world around them since the beginning of humanity. The regard grew with history in various patterns with every human civilization, and as cartridge clip passed, more disc everyplaceies were made that in in wholly in wholeowed humanity to r individually great heights in agriculture, architecture, social structure, and their culture. Great mathematicians continued extensive studies and experiments with various vagabonds that existed in their clock time to further improve the study. However, the construct of the speculative cast i was developed fairly recently. This essay is written from the fascination of abstract mathematical concepts, to develop the impacts of the multi hammer quantity takings on mathematics.In order to investigate this topic, I am required to view numerous proposed and established claims of the fanciful song history, and find these ideas being used wi th trus dickensrthy government issues to attain solutions to tasks we engage today in around former(a) subjects much(prenominal) as physical science, and astronomy. The purpose of this essay is to further research the signifi posteriorce of the imaginary bend, i, and its contributions to contemporary mathematics, natural philosophy, engineering, and other sciences. The expansion of knowlight-emitting diodege on this topic will further ride the study of mathematics in the future.Mathematics is the only when subject that peck explain the universe in a logical, unbiased, and lawful way. Mathematics has been in the roots of the development of advanced civilizations, in any(prenominal) time period. As humanity advanced, mathematics expanded. However, dilemmas were created as a consequence of its advancements. People created concepts deep down mathematics which a human brain could non fully understand. Concepts such as the imaginary subdue, i, are impossible to trul y comprehend with our circumscribed minds. However, the beauty of mathematics is that plane the or so impossible seeming, imaginary number, i has a history, and has significant impacts to modern mathematics.In mathematics, a square number is defined as an integer that is the product of more or less integer with itself. For example, 9 is a square number, as it is the product of 3 3. This can be written in an alternate notation, 32, which is pronounced as 3 squared. The wee square comes from the situation that the area of a square is the product of its 2 follow side lengths. A square number is always a autocratic comfort, as positive positive = positive, and negative negative = positive also. If squaring exists as an operation, there has to be the counter operation the square root, or . The square root takes a square number and reduces it to the single part that was squared to form the square number. For example, = 3. As all square meter are positive, square roots of negative number are illogical, or it was only considered illogical in the past= i, or the imaginary number, has the position of becoming a trustworthy number when raised to the power of an even number i2 = ()2 = 1, or i4 = ()4 = 1. A historical number implicate all of the rational add up, as in it is a whole number, or has an de end pointination decimal value, and all of the irrational numbers, which have unending decimal value. The feature film that all 3 types of numbers have in common is that they can be be in a number line, in some form. Unlike these real numbers, i has no way to be introduceed on a line. Furthermore, i is not the only imaginary number it is the unit imaginary number, used as a part of a daedal number. A daedal number is a combination of a real number and an imaginary number, taking the form of x + iy, where x and y are real numbers. For example, 12 5i is a difficult number. However, when x = 0, leaving only iy, such as 16i, it is then called a s tringently imaginary number. In contrast, if y = 0 leaving only x, the interlinking number is then a real number. In this sense, all real numbers are actually just subsets of composite plant numbers.In calculations, complex numbers are often paired with conjugates, which is defined as the binomial formed by negating the second term of a binomial, in the form of x yi in relation to complex numbers, it is the complex number with the imaginary part having the opposite sign. For example, the conjugate of the complex number 12 5i is 12 + 5i. These conjugates functions to eliminate the imaginary numbers from the denominator of a complex fraction, by multiplying the numerator and the denominator by the appropriate conjugate. The conjugate always = 1, so it does not alter the value of any equality. For instance, in an equation such asit can be simplified by multiplying (which equals 1) to it, resulting in= = yielding a single complex number,As shown, the imaginary number is not some abstract concept of virtually zero use it can be applied to real mathematics as only when as such. However, the idea of an imaginary number was not widely accepted until relatively recently in history, in the last 2 centuries or so.Before the concept of imaginary numbers were even conceived of, mathematics in the western world was restricted to geometry, led by the Ancient Greeks. The Algebra that modern mathematics is familiar with was invented by the Hindus, which was afterwards translated and improved by the Arabs, spear-headed by Arab Mathematician Al-Khwarizmi(780-850). At the time, however, the solutions to polynomials were restricted to positive solutions, omitting any negative quantities. Al-Khwarizmis algebra was then translated from Arab to Latin by Gerardus Cremonensis, and Leonardo Bonacci, also know as Fibonacci. (MerinoOrlando)The first recorded use of complex numbers in seen in the act upons by Gerolamo Cardano. Cardano was an Italian mathematician during the 16th century Renaissance. In fact, he is issued as one of the most influential mathematicians of the time, being a prominent member for the nameation of probability, binomial coefficients, and binomial theorems. He also transmitd to the invention of the combination lock, and the modern gyroscope. He publish over 200 works over the course of his lifetime. One of his famous works, the Ars Magna, published in 1545, included the problem To divide 10 in two move, the product of which is 40, or finding the solution to 10 + 40 = 0. (BogomolnyAlexander, Remarks on the account of tangled Numbers)Cardano usually used geometric algebra in order to avoid any use of negative numbers by considering some(prenominal) assorted forms of quadratic polynomial equations however, he decided to knead the question he declares impossible. He first divided 10 in half(a), making each 5. Then according to the methods he discussed in the previous section of his book, he squares 5, and subtracts 40 from it, leaving 15. He then square roots -15, which he then rack ups and subtracts from 5, leaving him with the roots (5 + ) and (5 ). In mathematical damage, his operation was 52 = 2525 40 = -155 (5 + ) (5 ) = 40.This is confirmed by simply multiplying the binomials(25 5 + 5 15)=(25 + 15) = 40.However, Cardano writes that in conclusion, this solution is useless, as it cannot be performed. (MerinoOrlando)The nigh significant milestone was achieved by the mathematician Rafael Bombelli in his (1572) work, Algebra. He was the first to recognize the significance of 1, and notates it pi di meno, or plus of damaging in Italian. Bombelli was faraway more familiar with the operation of negative numbers than Cardano, and establishes the rules when handling different signed numbers. His works are as follows the following is directly translated from his work in ItalianPlus times plus makes plus (1 1 = 1)Minus times disconfirming makes plus ( 1 1 = 1 )Plus times minus makes minus ( 1 1 = 1 )Minus times plus makes minus. ( 1 1 = 1 )He then annunciates the behavior of the number plus of minusPlus of minus times plus of minus makes minus ( = 1 )Plus of minus times minus of minus makes plus ( = 1 )Minus of minus times plus of minus makes plus ( = 1 )Minus of minus times minus of minus makes minus ( = 1 ) (BogomolnyAlexander, Remarks on the History of Complex Numbers)Bobelli took the same approach as other mathematician at the time when encountering negative roots as a solution to cuboid and quadratic equations, often omitting them completely, or disregarding them. However, he did attempt once to knead a blockyal victimisation imaginary numbers, and succeeded, without realizing its validity.The term imaginary was coined by the philosopher and mathematician Ren Descartes (1596-1650) he also coined the term real number to distinguish among real and imaginary roots of polynomials. He did not actually contribute to the mathematics aspect of i, but just provided a name for the severely understood concept.John Wallis (1616 -1703) was first to introduce a geometric rendition of complex numbers, and believe that negative numbers were larger than infinity, but fluent less than 0. This thought was shared by the famous mathematician Leonhard Euler (1707 1783), who introduced the symbol i as the symbol for , and linked the exponential and trigonometric functions in the famous reflectioneit = cos(t) + i sin(t).The geometric interpretation of complex numbers that modern mathematics agree with was first introduced by Caspar Wessel (1745-1818). Wessel treated complex numbers as vectors (which, he did not use the term vector), and derived most of their properties, including trigonometric form of multiplication (or, algebraic multiplication).The acceptance of complex numbers in mathematical society was further elevated by Carl Friedrich Gauss (1777-1855) with the use of complex numbers to Number Theory. Gauss introduced the term complex number, which he defined as the combination of real and imaginary numbers. However, i was still not fully accepted and understood until the mid-19th century, from the works of Sir William Hamilton, 9th Baronet, (1805-1865). He was responsible for the notation (x,y) he defined ordered pairs of real numbers of real numbers (a.b) to be a couple. This further implemented complex numbers as vectors or points on a plane, vector operators, and matrices. (MerinoOrlando)As one can bump from the historical track of i, complex numbers were abstract concepts of little value to mathematics until the last two centuries many, such as Cardano and Bombelli, disregarded i as a valid method for finding solutions. However, today, with a best understanding of complex numbers, we can now sort out equations they werent able to solve for centuries, with proper explanations to support the answer.With the knowledge of i, we are able to solve through with(predicate) with(predicate) some of the q uestions that the greatest mathematicians during the last few decades couldnt solve. One of the problems was derived from the cubic facial expression, invented by the Mathematician Del Ferro (1465 1526). To solve a quadratic equation, or an equation having the form , intend finding the values of x for when y =0. In other words, when the equation is graphed on a xy-coordinate graph, the x values of the points where the line crosses the x-axis. Conveniently, an Indian mathematician named Brahmagupta (597-668 AD) invented a quadratic formula in to facilitate the process of finding the solutions,where terms a, b, and c correspond with the earns in . (KnaustHelmut)While this is not the quadratic formula we are accustomed to today, , it was still a revolutionary way to solve quadratics. Del Ferro aimed to create a formula for cubic equations that have the same take of convenience as the quadratic formula., and he succeeds. The formula looked something like this , for the cubic equatio n in the form of Cardano later acquired this secretly guarded formula and modified it to a much simpler form,by using a lurch of variable x = to eliminate the x2 value to form a simpler cubic equation, . Cardano published this formula in the previously mentioned Ars Magna (KnaustHelmut). However, Cardano faced a major problem in a slightly different version of the equation, he anchor that his formula would break under certain circumstances when when blocked into Cardanos extra modified formula,= ,The result involves a square root of negative numbers these negative square roots were enough of a problem to cause Cardano to stop in his progress on this area. At the time, all negative roots as a solution was considered by mathematicians as the problems way of saying there are no solutions, and in most cases, it was true. Bombelli, however, while still not accepting the validity of the imaginary number, entire solving Cardanos problem. In the instance of a cubic, there has to be at least 1 real solution, because of the nature of the shape of a cubic on the xy- graph. At least 1 point had to cross the x- axis, at all circumstances. This is one of the Fundamental Theorems of Algebra a polynomial function has to have n number of solutions for the largest nth power. Through testing some integers, Bombelli found that 4 is one of the solution to the equation43 = 15(4) + 464 = 60 + 464 = 64The solution, as anyone can see, is a real number for this to be the case, Bombelli realized that the root of i part of each half of the equation needs to cancel out, or equal to zero when added to energizeher, like thisHe then used this idea to form complex conjugates, and where and b are constants that we need to obtain, which we equate to each half of the equationWe can then start solving for the constants by cubing two sides of the equation)33= )( + = =Now we need to separate the real and the imaginary partsandNow since we know that When we plug it into one of the deri ved equation,With these values, we now know that andWhen we occlusion these values, we can see that they do indeed equal what we started with = = And more importantly, when we add the two parts together as the formula tells us to do, we get the solution, 4.= 2 + 2x = 4Bombelli definitely solved Cardanos problem, using Interstingly, neither the original problem nor the answer had anything to do with but in the method, we can see that by extending the number system to include as a valid value, it is crucial to finding the answer, as the Mathematician Jacques Hadamard quoted, the curtlyest path in the midst of 2 truths in the real domain passes through the complex domain. However, when Bombelli succeeded in finding this solution, he discarded his discovery and considered as sophistries, or tricks that only exist to solve problems like these. We, as thinkers of modern mathematics, know that this is not true, and there are much more sophisticated aspects to complex numbers. (Bogo molnyAlexander, Remarks on the History of Complex Numbers)How, then, are imaginary numbers valid? jump of all, we need to understand exactly what limitations real numbers have. We are already familiar with the number line it is an infinitely long line comprised of all real numbers, positive and negative. It includes all integers, all fractions and decimals, and even irrational numbers, or numbers with infinitely long decimal places, such as or . However, there is no place for on this line, and for centuries, no mathematicians could find a place for it because of one reason i is 3-dimensional. In other words, because of the fact that i does not fit in a real line, all multiples of i, positive and negative, form another line, perpendicular to the line of real numbers. In the xy- coordinate plane, i forms a third axis perpendicular to some(prenominal) the x-axis and the y-axis.With this comprehension, we can further define complex numbers as surgical operation points or vectors in the Complex Plane. A vector is defined as a quantity having direction as well as magnitude, curiously as determining the position of one point in space relative to another in a plane. This property of i opens up exponentially many possible uses of i in the 3-dimensional physical world.The term imaginary make the perception of i to be some abstract, unexplained mathematical fallacy by many people, and it was true, until last 2 centuries. The truth is, i is as real as any other number many people today argue that the Cartesian name of the value, the imaginary number is misleading, because of all of the real potentials the value actually holds. In physics alone, complex numbers are used to project the amount of hear on structures, resonance, for the manipulation of large matrices in modeling various figures, and is particularly used extensively when dealing with electrical current, and wavelength.In electrical engineering, values can be divided into scalar quantities and complex quantities scalar is what real numbers are called in the scientific language. Some examples of scalar quantities include voltage produced by a power source, the resistance of any gene in an electric circuit, measured in ohms (), and electrical current through a wire, measured in amps. During some circuit manipulation, electrical engineers found that in alternating current circuits, voltage, current and resistance, or in physics terminology, resistance measured in AC, were not outputting scalar quantities like other DC circuits. They instead had alternating direction and amplitude (or magnitude), which as a result, had another dimension of frequency and phase shift. Engineers found that it was impossible to engineer and represent all of these non-scalar values with real numbers therefore, they turned to complex numbers, that were multi-dimensional in nature, and could express the 2-dimentional quantity of frequency and phase shift in a single complex number. However, in physics a nd electronics, the letter j is used in the place of i to prevent confusion, as the letter i is used to represent the value of current. Therefore, scientists would write the complex numbers in the form of . (RobertsDonna)In electrical science, engineers are required to calculate missing values based off of given data, using peculiar(prenominal) equations such as E = I Z, where E = voltage, I = current, and Z = impedance. For example, if the voltage in a series circuit is 45 + j10 volts and the impedance is 3 + j4 , the scientist is required to be able to calculate the current by simply using the equation and inserting the values amps (RobertsDonna)In contrast to some of the math problems we solved previously, the answer to these questions remain complex, which is natural, since the value still has to represent a 2-dimensional quantity of phase changes and frequency. These data are applied to anything electronic, from computers to swear out machines, from someones smartphones to t raffic lights imaginary numbers are being used in the real world everywhere, which is why there are even arguments roughly the terminology of imaginary should be edited to an updated, mathematically correct term, such as lateral numbers for its lateral behavior in complex planes. i is truly valid.The concept of i existed for such a short period of time, yet what it allowed us to accomplish within that time is beyond imaginable. Society saw an explosion of technological development, improved machines, and programming all of which would have been impossible without the understanding of i in the world contain by technology and electricity. However, the most crucial achievements of i is that from a number that we considered to not exist in this world, we learned more about ingrained laws of physics, the dimensions we live in, and the world, the real world we need to learn from it, and appreciate it for existing.References Bogomolny, Alexander. interactional Mathematics Miscellany an d Puzzles. 2015.

A Report On Romeo Juliet English Language Essay
A Report On Romeo Juliet English Language analyzeWhat methods does Shakespeare use to show the characters feelings and thoughts in represent 3, Scene 5 of Romeo and Juliet? rationalize the barbs importance and consider how different audiences might respond.Shakespeare wrote the stand for, Romeo Juliet more than 500 years ago and he used umteen techniques to make it interesting. Using techniques in a play is really all important(p) because it makes the play effective and to a fault makes the reader understand the play better. Shakespeare uses a variety of techniques to show the characters feelings in answer 3, Scene 5 of Romeo Juliet. For example, Shakespeare uses insults, antitheses, list, ambiguous statements and many more.In Act 3, Scene 5, passe-partout Capulet wants Juliet to marry Paris as he is pleasant and honour up to(p) person. Previously, he was extremely happy as his only girl is going to get hook up with. But when she says, No then the mood of lord Capulet s changes drastically, in that respectfore his mood goes from happy to angry, soft to cutting and weak to strong.Furthermore, Shakespeare uses many techniques to express Lord Capulets anger with Juliet. One of the techniques that Lord Capulet says to Juliet is insults. This is when in Act 3, Scene 5 he says, Out, you green-sickness carrion Out, you baggage You tallow-face By saying this he implies that Juliet is a burden and a disease to him. here(predicate) Lord Capulet is universe extremely rude by humiliating his only own miss resembling this.Lord Capulets daughter, Juliet, is the most important character in this scene as it is primarily based on her. Shakespeare shows Juliets emotions by using statements with replicate meaning (ambiguous statements). For example, when Juliet says, Delay this marriage for a month, a week, maam Capulet thinks that she is too young and necessarily some epoch. But what she actually means is that she needs some time to think closely what she is going to do, to be able to be with Romeo.Juliets mum, Lady Capulet is antagonised by Juliets response because she said No which was reply that nobody has imagined. This is clear when Juliet asks Lady Capulet for help but she replies, Talk to me non for Ill not speak a word. This is just like saying, Talk to my transcend, not to my face. This clearly shows how rude, arrogant and abusive Lady Capulet is.The Nurse, on the other hand, is really worried about Juliet because she is already unite and her parents are forcing her to marry Paris. When the Nurse says, I think it best you married the county. O, Hes a recognizely gentleman, she uses vocative because she is really apprehensive about Juliet getting married to Paris, as she is already married to Romeo.In this textual matter an exclamation mark is used and punctuation is really important when writing a play as the reader flowerpot know how characters can say their dialogues. For example, Hang thee, young baggage diso bedient wretch Here Shakespeare uses a comma, to show there is a pause in the dialogue. Also, he uses exclamation marks, which tells the reader that Lord Capulet says the dialogue in a harsh way.Moreover, it also depends on the audience how they exit interpret and react to the dialogue. For example, when Lord Capulet say hang, thee, beg, starve, die in the streets. There is a techniques used her which is list. Also, if there were modern audiences then they would interpret this as Lord Capulet being actually harsh on his daughter but on the other hand the Shakespeare audiences will interpret as Lord Capulet doing the right thing and considering that Juliet is the iodine who is wrong because in those times there were more arrange marriages than love marriages.Lord Capulet also tries to gather sympathy from the modern and Shakespeare audiences. For example, when Capulet says, Day, night, hour, tide, time, work, play, alone, in company. He is saying that he has looked after and cared for Juliet for every bit of his flavour. Also, this text from the play is a technique, which is called list. Capulet says this so he can gather sympathy from the audiences. He will get sympathy from the Shakespeare audience because in Shakespearean time the father chooses the groom for the bride. On the other hand, the modern audience will sympathise with Juliet because they think that a women have the right to choose her groom. after all she is the one who is going to be married and spend her life with her husband.In conclusion, using techniques in a play is really important for a play, as it gives the play a new layout. Also, Shakespeare puts the characters thoughts and feelings in their speech. He builds up dramatic tension between characters which conveys their emotions and therefore portrays their relationship.

The ideas of work environment ethics is related to how people who work for and who run the business applies their perception of right and wrong in a way they conduct the business . It is good for the company and the companies product to bear on its value at the same beat retain affirmard. This would happen, if the company stand its foot on the honourable behavior. All the existing companies should choose to deport honourablely to keep their relationship between their customers and co workers. This is very beta in businesses now days to increase their sales of product and services. All the business should maintain first class service.Being ethical also refrains from the companies name or by product also being big and it also keeps the customers happy. But if the attr meet of the company or the manager misleads the employees or the organisation in a wrong direction, than the rewards disobedient behavior. Some of these wrong behaviors that argon make by the leading in a bad physical composition could be fraud, cheating and stealing. Even though by lying or cheating might non be a red for the company, but its like ta king the organization and its products and services to a major(ip) risk. To run a good ethical behavior organization one must en positive(predicate) that the leaders abide by the rules and regulation of the specific organization. And the leaders should throw away the similar ethical thinking of what the organization has.The risks of the organization could take place by running businesses by wrong dexterity are as follows-Loss of customersBad name of the organization in the existing high society.Prevents the organisation from growingBankruptcyRisk of being sued. split up of consumer responsibility.Loss of good employees.In an organization, employees should form a system to figure out any ethical problem that arises with the help of leaders and the managers. As a leader the first step is to specify the appropriate behaviors not solely by words but also by your action.To prevent wrong dilemma at a oeuvre the manager or the leader should put up employees with proper training d uring the orientation.If you want to make sure your workplace is a good role model of an ethical behavior (doing what is right) the leaders of the organization should ensure the employees continue to follow the rules that are determined out passim the entity. While it is hard for a company to write about of the simple rules and regulations as long as the general rules are give out, so the company should ask to live by the response of the behavior that they make unethically and hold them accountable for doing so.According to the workforce in todays business culture all individuals should be prepared to deal with stressful situation. Such as when employees are caught for doing previous unethical decision they moolah blaming the victim (he was stupid enough to fall for it), and finger pointing (she does the same thing, and you never call her on it) will not be tolerated. To make sure that the unethical behaviour does not arise, therefore companys written rule is arbitrary for ev ery individual. Also all the rules should be clear easy to understand, and affix to notice board. Even though it is easy to understand the ethical and unethical behaviour thats why the rules made for employees should be memorized. This is how your business can aline its way through the gray areas, and the way out on the other end of the tunnel.My past job was also a broad gravel that the ethical behaviour does pay off in long run. This was when I was certify in Sydney. I met Brian Hussain, who was very keen on opening move up his own business in a cable car detailing. He told me that he was going to offer me a job of a manager, since i had two years experience in the detailing of cars. So i took his offer since the income offered to me was great. Brian Hussain spoke to the proprietor of Premier Parking, which is well have it offn in Australia, to go provides with him in 1998. They both came to an agreement and decided to open up the detailing shop by the name off Elite go ndola car dish out in May 1998. The first Elite gondola Care was opened in the parking lot of Leichardt mall, Sydney. So i started works from the first day of the opening, business was running a bit loosen up since most people were not aware of it that the car wash was in the parking lot. Months went past and the business started to make progress, by the end of 1998. The turnover was almost three clocks to a greater extent than what we usually use to make. And the workers were unfeignedly good but the only issue i had that they had a student work permit with only 20 hours of work availability. Since the Car dud was open for 7 days, it was important for me to have at least quartette staffs every day except Mondays. Weekends use to be the most officious days of the week, and in order to get the work through I had to ask the employees to do extra hours, which the students 20 hours were exceeded. The immigration was ok with the students if they went over the 20 hour to 23 hours, as long as they dont borrow it often.Brian Hussain, use to come around the work place almost every afternoon just to check up on the hours of the staffs and the sale we did throughout the day. So what Brian Hussain was, cutting down the hours of work the students did to 20 hours even if they worked work on 22 to 23 hours. What was done by Brian Hussain was wrong, but i authentically couldnt do much since he was the boss. The actions of Brian Hussian, made the workers leave, which also made us loss some of our rightfully good customers. Because the work was not done properly and the time frame that the customers had to wait for their vehicles to be cleaned was also stretched.In 1999 i arranged a meeting with Brian Hussain and his pickner in the business, who was the owner of premier car park. I told him that the decisions that Brain Hussian made was not ethical and it also affected our business in a great loss. I also suggested that on the busy days of the week if the workers w ork really hard and skip there lunch to get the work done we should give them a bonus or reward for their effort contributed to the car wash. They knew it will be some extra expenses for the business, but they agreed to do as i suggested.After these changes were made there was a great progress and growth in the business environment, even the workers were satisfied to what the rules that was laid by the organization. By the mid 1999 the turnover was so good that Brian Hussain and his partner decided to open another car wash in ingeminate Bay, which i know was a great idea, because the people that lived there are rich and drive expensive cars.And by the end of 1999 Elite Car Care had a great name in the market of car wash, which made the old customer that we lost in Leichardt to come back to us. This is why i strongly suggest that ethical behaviour pay off in long run and also maintains a wakeless relationship with the customers and employees. It is also give tongue to what goes ar ound comes back around this is a true saying and I believe to stand by it.Referenceshttp//www.suite101.com/ national/ethics-in-the-modern-workplace-a32979http//www.asla.org/nonmembers/publicrelations/pressreleases/press071801.htmhttp//findarticles.com/p/articles/mi_m0EIN/is_2001_July_20/ai_76649894/Question 2 companys pertain will be reflected by the ethical leaders, how the decisions are made and they need to be people oriented. leaders are there to set an example in an organisation and by doing that they resolve the prejudicial impact on the society. Leaders show ethical behaviour by doing right thing and at the same time they help to motivate the followers. They also help the followers achieve the clean knowledge to its highest peak. In reality ethical leaders cover more encouragement of ethical behaviour. For example, repeating the ethical behaviour programs in their daily life. By being ethical the society helps the base of the business environment to be strong and steady. R ight condition should be created by ethical leaders and also organisational culture to encourage the development of ethical behaviour. With a good ethics a leader can convince the world.Society has been represented by a leader or leaders at different levels for e.g can be city, town, village, industry, club, association, country, etc. Such as regular army is well known of its power and ethical behaviour, which is unmatchable leader in the world. Another example would be an American leader sent the ground forces army to Iraq to resolve the conflict they had in Iraq.The lack of corporation and rear by the leaders can have a great minus impact on the society and the environment both. This could also result in the rise of crime, corruption, pollution, and social conflict. Todays people blame the leaders for things they have negative impact on the society reason being lack of reliance on the leader. For example the voters of Canada no longer believe that their leaders are honest. Mo re than half the people have researched by the British Columbia, which said the government is making their life worst.Being an ethical leader its not just making, doing the jobs that makes the business benefit, but it also must be every bit benefit for the people and the society. To complete accurate information through leave leaders need to suggest on professional, personal and legal grounds. By doing this you will have a peace of mind and have no guilt as well as having a respect for the disposal of employees. A leader being unethical doesnt just have a impact on the employees but also on the society. If this happens, it could result in a big collapse. One of the great examples that was using a unethical behaviour and then collapsed, is Enron.We can also describe ethical lead as an trustworthy also describe ethical leaders transparent, honest and trustworthy culture that would later on help them achieve long lasting position of leaders in their groups, nations and organisations . Great example would be a well known person from India his name is Mahatma Gandhi for his great leadership style.In todays generation everybody expects the leaders to have the ethical behaviour and set in the society. By having such a large number of macrocosm its hard to separate the evil ones from the good ones. Thats why it gets hard to stick ethical and honest in the world of competition. To improve the ethical leadership in the business environment it is important to introduce ethical from the cover version first.A leader with ethical behaviour is also a part of social responsible organisation at different levels, which includes legal, economic, and ethical. If a company cannot look after its legal and economics responsibilities then it is not socially responsible. Sometimes company need to do more than it is required to have good impact on the business and in society too. To pay back more socially responsible a company needs to contemplate its ethical actions. Apparentl y company should strives in order to provide ethical treatment to all stakeholders away from shareholders. If the organisation allows their employees and the community in the decision making process as stakeholders then this will have a great impact to reduce negative and at the same time improve the positive outcome for each group. By doing this it also improves the companies action becomes more and more socially responsible.For a leader to have a ethical behaviour in a business organisation, his own thoughts and ethical behaviour should match with the business and society. In todays society leaders should know what kind of behaviour either positive or negative impact on others and the people around them. An ethical leader also helps the business to have a better and healthy communication between the business and society.Some of the good examples of how ethical leaders or an organisation helps the society are as follows-Disaster Relief whereby for example telecom provide a support to society by proving resources and working twenty quatern hours , seven days to recompense communication to homes and businesses. While working to restore the communication, telecom also provide free calls diverts to all customers and also a free wireless broadband in society.It is also a good thing that a society benefits from ethical behaviour of an organisation because the employees are part of the society.

When his master died, he claimed to be free because he had lived in s tates where slavery was illegal.
