George Bass :: essays research papers
à à à à à As I walked to the Daly Science Center from Benson Memorial with a stomach full of ridiculously expensive cheap food, I expected the lecture of Dr. Bass to be more or less of a rehashing of what he spoke to our class about earlier in the day, albeit with a few more and older people watching. My first surprise came as I opened the door of lecture hall 206 and saw all the students sitting on the stairs. I myself was relegated to sitting at the very top of the stairs, near the door, with other students sitting on nearly every stair all the way down. As soon as I sat down I was immediately drawn into the lecture by Dr. Bassââ¬â¢s immense passion and visible love for his field of work. My second surprise came as I listened to his tales of various escapades and adventures along the Turkish coast. The most impressive part of his lecture was his comfort in not only lecturing on the intellectual context of his work, but also his willingness to share his personal experi ences with a large group of strangers. The longer I listened to Dr. Bass speak the more honored I felt to be in the presence of a true legend of archaeology. At first I did not understand why he included the slide and story about the beach where him and his wife spent their honeymoon forty years ago. However, towards the end of the lecture when he brought us back to that same beach, I was amazed that it has come to be known as ââ¬Å"the beach where the Americanââ¬â¢s wereâ⬠. You notice I say brought ââ¬Å"usâ⬠because that is exactly what Dr. Bass did Monday evening. He brought us as an audience with him on his trips to the Near East and down to the sea floor to look for amphoras and scarabs in shipwrecks, which before his work nobody knew existed. à à à à à When he showed the slide of Queen Nefertitiââ¬â¢s scarab I though no other find he has made could top it. However, upon further reflection I believe his discovery of the oldest ââ¬Å"bookâ⬠, and glass were more historically significant items. In my humble opinion, Dr. Bassââ¬â¢s most extraordinary finding was his work outside of the dive sites. His theories regarding contact and trade between Egypt and the Near East, Greece, and the Middle East in the Bronze Age have gone from mere speculation to widely accepted academic fact as a direct result of his research and writing.

Black on Black Crime Essay
Undeniably, stereotyping has always been rampant in our society. These stereotyping may either be through gender, age, occupation and the most popular of all, perhapsââ¬ârace. Part of stereotyping is associating a certain group of people to whether good or bad demeanor. And perhaps, almost known to all is the black-on-black crime. This kind of crime is usually pushed to happen due to the prejudice of the society. As Black Americans are subjected to discrimination and injustice, black-on-black crimes are most likely to occur. Black-on-black crimes are the kind of crimes which are committed on Blacks with their fellow Blacks as the offenders. At present, the African Americans remain more segregated that any other racial group in the world. Some of them even experience ââ¬Å"residential isolationâ⬠(Quillian, 1999). Past studies show that ââ¬Å"white flightâ⬠or the avoidance of white is the main reason of racial discrimination. While there are only 12 percent African American living in the United States, 45 percent of the victims of murder in year 2002 also come from them; 91 percent of them are killed by their fellow Black Americans. Statistics show that homicide tops the list of the leading causes of death among Black men, while suicide in landed on the second notch on the causes of death among Black women aged 15-24 (Greaves). These figures or statistics, of course, are just a reflection of social reality. Racial discrimination, though not as rampant in the past decades still hounds out society that is a great factor contributing to the crime rate among Black Americans. ââ¬Å"BLACK-ON-BLACK CRIMEâ⬠PAGE#2 Prior Research Despite the societyââ¬â¢s eventual tolerance on racial differences, there are still studies that show that whites do not prefer in places where there are a lot of African Americans thriving in. In a research survey conducted, most of the white Americans who were asked in the survey said they prefer living in a community where the population of African American is less than 30 percent. (Clark) Studies showing the trends of mobility actually show that neighborhoods or communities with relatively high population of Black families have the tendency to have a ââ¬Å"collapsedâ⬠population of white families (Quillian 1999). This means that white Americans tend to move out the place if it is more dominant of the black Americans. In the long run, these neighborhoods would be dominated fully by black Americans. Perceptions on Crime Empirical studies were never really enough to back up the perception of neighborhoods and communities about crime. There are no really a significant number of studies which focus on the black-on-black crimes. But then there are two main factors that are believed to influence the perception of a neighborhood towards crime. First is the observable characteristic which is the neighborhoodââ¬â¢s racial composition. In the United States, for example, most of the neighborhoods or communities can be categorized into either dominant of blacks or dominant of whites. Factors like economic class where an individual belong is not easy to gauge based on physical characteristic. ââ¬Å"BLACK-ON-BLACK CRIMEâ⬠PAGE#3 The second factor would be the stereotypes that relate a certain group of people with crime. An example of this would be the African-American or the Blacks who are often associated with rampant crimes known by all Americans (Devine and Elliot 1995). Studies furthered that information that are consistently seen are stereotypes are most likely to be noticed or remembered by people than those information stereotypes that are not usually used (Robert, Evans, and Fulero1979). Stereotypes may also lead to the salience of the stereotypes which are associating certain groups of people on committing crimes. Thus, media reports would most likely to focus on news reports that are guilty of stereotyping. These kinds of media reports reinforce the association of crime and race in the minds of the people, or to be specific, to the mind of the audience. Causes Divergent to the common notion that racism or discrimination is the main cause of black-on-black crime, there are actually a lot of factors causing the perpetuation of such crimes. Racism or discrimination is not the sole reason for the existence of ââ¬Å"evil attitudes. â⬠Among of them urging ââ¬Å"evil attitudesâ⬠are: high rates of out-of-wedlock pregnancies and births, abortions, child abuse, and broken families that continually hound the different black communities. Empirical data show that teenagers or the young adults are the ones who are usually involved in troubles, thus increasing their vulnerability to committing crimes. These data apply to Black Americans. But these figures cannot actually generalize all of the Black Americans. ââ¬Å"BLACK-ON-BLACK CRIMEâ⬠PAGE#4 In the case of Unites States, youngsters (or the Black Americans to be specific) are usually involved in peer groups some even call it ââ¬Å"gangtas. â⬠Majority of these kinds of groups are said to be constantly involved in riots or rumbles mostly with their fellow teenagers and Black Americans. Teenagers are groups of peers who seem to act like a ââ¬Å"broken windowâ⬠which signals crime (Maxfield 1981). This most likely applies most likely to young black men (Anderson 1990) in neighborhoods with ââ¬Å"mixed racialâ⬠inhabitants. Combating Black-on-Black Crimes The problem on black-on-black crime cannot be instantly resolved. The way towards the solution of this social problem would really entail a lot of efforts and factors. It may take years, decades or more for us to get over or to lessen the rate of black-on-black crimes. But then, if we are really determined to combat or at least lessen the figures of the occurrence of black-on-black crime, then, we will surely be successful in our aim. This plight is not just the plight of the Black Americans. Everyone is affected when Black-on-black crimes happenââ¬âwhether directly or indirectly. As follows are the probable solutions that may address the social plight on black-on-black crimes. Some may be too mundane for some, but it will contribute to the eradication of the problem. One of the main factors, perhaps, pushing the Blacks to commit crime against their fellow Blacks is their low self-esteem. We can avoid the Black on Black Crimes by giving them enough and proper education not only to the African-American children but also to the Caucasian ââ¬Å"BLACK-ON-BLACK CRIMEâ⬠PAGE#5 children. It is because, the usual educational curriculum among schools, especially in the K-12 levels, is teaching that European descendants are the superior race while the Blacks are inferior. Another is ââ¬Å"identifying and helping potential offenders. â⬠We should first identify who are the common groups of people are involved in black-on-black crimes. Researches show that black-on-black crimes usually happen among the youngsters. We should help them in overcoming their unpleasant behavior. Those behaviors are, in reality, brought about also by some social factors. There are certain problems within our society that need to be immediately addressed before we could completely dwell in our problem on black-on-black crimes. More so, better law enforcement could also help in eradicating the problem on black-on-black crimes. Also this will not really guarantee that crimes will never happen again, this will ensure that there is a strict monitoring of what is happening in the society. But then, there should also be also respect on the Black offenders. They may be criminals, but they should still be treated as human. If offenders are immediately identified, there will be lesser crimes as the police or the authorities are faster in terms of solving the crime. Part and parcel of this solution is also the strict implementation of available laws. If authorities are not strict in implementing their own policies pertaining to crime, offenders will not be intimidated and ashamed to commit any crimesââ¬âwhether it is a black-on-black crime or not. ââ¬Å"BLACK-ON-BLACK CRIMEâ⬠PAGE#6 And last but not the least, there should be ââ¬Å"community involvementâ⬠in fighting this social predicament. It is not just an issue of Blacks against Blacks. It is an issue concerning everyone. The Blacks should not be treated differently by the society. It is just the complexion that differs, anyway. In a study conducted by the Chicago Crime Factors and Neighborhood Decline in 1978, respondents were asked about their perception on the crimes that are happening in their community. The survey was done through a telephone survey involving 3300 household members in eight chosen community areas in Chicago. The communities were chosen in terms of their racial composition, property values, and crime rates. In each community, there were 400 household members chosen randomly. Based on the results, there is a significant association of racial composition to the respondentsââ¬â¢ perception on the crimes in their neighborhood. As hypothesized, as a neighborhood has a higher percentage of Black American inhabitants, the respondents have higher perceived rates on the crime rates within their community. The association of Black Americans with crime rate is both applicable to Black and White Americans, who are the respondents of the study. The survey conducted in Chicago just shows how the Black Americans are perceived by White Americans and even by their fellow Black Americans. They are associated with crimes. We have to break this particular stereotype than Black Americans would mean higher crime rate. Instead of being mere observers of this social plight, we do something to break this kind of problem. ââ¬Å"BLACK-ON-BLACK CRIMEâ⬠PAGE#7 Black-on-black crimes usually happen because of the treatment that the Black Americans get from the society. If we open about our racial differences, Black-on-black crimes would be lessenedââ¬âat least. We would just usually smirk if we hear stories of crimes committed by Blacks on their fellow Blacks. Our mind set is that, we are not affected, anyway. Some even blame the Blacks alone for doing those ââ¬Å"criminal acts. â⬠We tend to forget that everything is connected to everything else. We tend also to ââ¬Å"wash our handsâ⬠over the issue of Black-on-black crimes. We are unmindful that we have also our part on the perpetuation of these kinds of crimes. Conclusion The society is a very crucial factor towards the development of an individual. The environment is a vital determinant on what kind of individual one could be. How the society looks on a particular group of people usually reflect the demeanor of an individual within the group. For example, the case of the Black Americans is a clear manifestation of the societyââ¬â¢s prejudice. The salient issue that Black Americans are most likely to commit crimes against their fellow Black Americans affects the psychological being of the Blacks. In a nutshell, it is the society which is the main root of Black-on-black crimes. Ironically, it is also the society which will play the most important and most crucial part towards the resolution of this social plight. A society with open mind is what we need. A society that is void of prejudices, stereotypes, and judgment. By this, black-on-black crimes will be solved. Outline I. Introduction II. Overview of Black on Black Crimes A. Prior Researches B.

The Birth Of Coca Cola Essay - 1968 Words
Economy (The Birth of Coca-Cola into our Consumer Society) From the 20th century onwards, marketers realized that in order to increase consumer numbers products needed to become less industrialized and more specialised and personalised, which could be achieved by focusing specifically on consumer desires (Lury, 2011). Manufacturers are now spending more time and effort on the visual display and uniqueness of their products. As a result, our society has a vast range of commodities available to us, in every size, shape, colour, model, and flavour you can imagine to cater to every taste. The birth of Coca-Cola began in 1886 when Atlanta pharmacist Dr John S. Pemberton created a soft drink that could be sold at soda fountains. He made his own syrup flavour and mixed it with carbonated water at the local pharmacy, resulting in high praise from those in the community who tasted it. His partner and bookkeeper Frank M. Robinson invented the name ââ¬Å"Coca-Colaâ⬠, and was also responsible for designing the distinctive cursive font. When it was first made, Coca-Cola was sold for 5 cents per glass, and in the first year Atlanta sold about 9 servings per day. Now, daily servings make about 1.9 billion dollars around the world (World of Coca-Cola, 2016). Because Coca-Cola was such a unique creation at the time, it was important that it also had a unique appearance to catch the attention of consumers. In 1916, idea of a contour bottle was conceived.

Role of Youth in Eradicating Corruption Free Essays
string(70) " lets in laser light just as well and remains unaffected by the beam\." Laser and its medical applications Presented by S. vignesh J. sabastian The Advent of the ââ¬Å"Laser Scalpelâ⬠Early experimenters with medical lasers pointed out that there are surgical operations that are difficult to perform with the conventional scalpel and that a laser beam might be used instead. We will write a custom essay sample on Role of Youth in Eradicating Corruption or any similar topic only for you Order Now Initial trials showed that a finely focused beam from a carbon dioxide gas laser could cut through human tissue easily and neatly. The surgeon could direct the beam from any angle by using a mirror mounted on a movable metal arm. Several advantages of laser surgery quickly became apparent. First, the light beam is consistent, which means that it gives off the same amount of energy from In this photo taken during open-heart surgery, a doctor uses a laser probe to punch small holes in the patientââ¬â¢s heart muscle to increase the organââ¬â¢s blood flow. one second to the next. So as long as the beam is moving along, the cut it makes (the incision) does not vary in depth; whereas when using a scalpel a doctor can accidentally make part of the incision too deep. A second advantage of the surgical laser is that the hot beam cauterizes, or seals off, the open blood vessels as it moves along. This works well mainly for small vessels, such as those in the skin. The doctor still has to seal off the larger blood vessels using conventional methods. ) Still another advantage is that the cells in human tissue do not conduct heat very well, so the skin or any other tissue near the laser incision does not get very hot and is not affected by the beam. This advantage of laser su rgery is very helpful when a doctor must operate on a tiny area that is surrounded by healthy tissue or organs. It should be pointed out that the ââ¬Å"laser scalpelâ⬠is not necessarily the best tool to use in every operation. Some doctors feel that while the laser is useful in some situations, it will never totally replace the scalpel. Others are more optimistic and see a day when more advanced lasers will make the scalpel a thing of the past. The second of these views may prove to be the most accurate, for surgical use of lasers is rapidly advancing. At first, lasers were considered most effective in operating on areas that are easy to reachââ¬âareas on the bodyââ¬â¢s exterior, including the skin, mouth, nose, ears, and eyes. But in recent years doctors have demonstrated remarkable progress in developing laser techniques for use in internal exploration and surgery. Of course, in order to be able to direct the laser beam the doctor must be able to see inside the body. In some cases this is a simple matter of making an incision and opening up the area to be operated on. But there are situations in which this step can be avoided. Cleaning Arteries with Light For instance, lasers are increasingly used to clean plaque from peopleââ¬â¢s arteries. Plaque is a tough fatty substance that can build up on the inside walls of the arteries. Eventually the vessels can get so clogged that blood does not flow normally, and the result can be a heart attack or stroke, both of which are serious and sometimes fatal. The traditional method for removing the plaque involves opening the chest and making several incisions, a long and sometimes risky operation. It is also expensive and requires weeks for recovery. An effective alternative is to use a laser beam to burn away the plaque. The key to making this work is the doctorââ¬â¢s ability to see inside the artery and direct the beam, another area in which fiber optics and lasers are combined into a modern wonder tool. An optic fiber that has been connected to a tiny television camera can be inserted into an artery. These elements now become a miniature sensor that allows the doctor and nurses to see inside the artery while a second fiber is inserted to carry the bursts of light that will burn away the plaque. The technique works in the following way. The fiber-optic array is inserted into a blood vessel in an arm or leg and moved slowly into the area of the heart and blocked arteries. When the array is in place the laser is fired and the plaque destroyed, and then the exhaust vapors are sucked back through a tiny hollow tube that is inserted along with the optical fibers. When the artery has been cleaned out the doctor removes the fibers and tube, and the operation is finished. This medical process is known as laser angioplasty. It has several obvious advantages. First, no incision is needed (except for the small one in the vessel to insert the fibers). There is also little or no bleeding, and the patient can enjoy total recovery in a day or two. Laser angioplasty does have some potential risks that must be considered. First, when the laser beam fires at the plaque it must be aimed very carefully ecause a slight miss could cut through the wall of the artery and cause serious bleeding. The patientââ¬â¢s chest would then have to be opened up after all. Another problem involves small pieces of burnt debris from the Surgeons use a tiny laser to cut away tissue in a gallbladder operation. The laser and a tiny camera are inserted into the navel, so no abdominal incision is necessary. . Lasers Heal and Reshape the Eyes Some of the most remarkable breakthr oughs for medical lasers have been in the area of ophthalmology, the study of the structure and diseases of the eye. One reason that laser beams are so useful in treating the eye is that the cornea, the coating that covers the eyeball and admits light into the interior of the eye, is transparent. Since it is designed to admit ordinary light, the cornea lets in laser light just as well and remains unaffected by the beam. You read "Role of Youth in Eradicating Corruption" in category "Essay examples" First, the laser is very useful in removing extraneous blood vessels that can form on the retinaââ¬âthe thin, light-sensitive membrane at the back of the eyeball. It is on the retina that the images of the things the eye sees are formed. Damage to the retina can sometimes cause blindness. The laser most often used in the treatment of this condition is powered by a medium of argon gas. The doctor aims the beam through the cornea and burns away the tangle of blood vessels covering the retina. The procedure takes only a few minutes and can be done in the doctorââ¬â¢s office. The laser can also repair a detached retinaââ¬âone that has broken loose from the rear part of the eyeball. Before the advent of lasers detached retinas had to be repaired by hand, and because the retina is so delicate this was a very difficult operation to perform. Using the argon laser, the doctor can actually ââ¬Å"weldâ⬠the torn retina back in place. It is perhaps a strange coincidence that Gordon Gould, one of the original inventors of the laser, later had one of his own retinas repaired this way. Another condition that affects the eye is glaucoma, which is characterized by the buildup of fluid in the eye. Normally the eyeââ¬â¢s natural fluids drain away a little at a time, and the eye stays healthy. In eyes impaired with glaucoma the fluid does not drain properly, and the buildup affects vision; blindness can sometimes result. In some cases drugs can be used to treat glaucoma. If the drugs fail, however, many doctors now turn to the laser to avoid onventional surgery. The laser punches a hole in a preplanned spot and the fluid drains out through the hole. Again, the treatment can be performed in a doctorââ¬â¢s office instead of a hospital. Using Lasers for Eye Surgery The laser works like a sewing machine to repair a detached retina, the membrane that lines the interior of the eye. The laser beam is adjusted so that it ca n pass harmlessly through the lens and focus on tiny spots around the damaged area of the retina. When it is focused, the beam has the intensity to ââ¬Å"weldâ⬠or seal the detached area of the retina back against the wall of the eyeball. The patientââ¬â¢s eyeglass prescription is literally carved inside the cornea with the beam of an excimer laser [a laser device that produces pulses of ultraviolet, or UV, light]. A small flap of the cornea is first removed with a precision knife . . . and an A patient undergoes eye surgery performed by a laser beam. In addition to treating detached retinas, lasers can remove cataracts. inner portion of the cornea is exposed to the excimer laser. After the prescription is carved, the corneal flap that was opened is then put back into place over the ablated [surgically altered] cornea. 6 LASIK does not come without risks. The changes it makes in the cornea are permanent, and the danger of unexpected damage is ever present. However, the procedure has become increasingly popular each year; about a million Americans had it done in the year 2000, and about four thousand surgeons in the United States were trained to perform it. Some Cosmetic Uses of Lasers Medical lasers are also widely used for various types of cosmetic surgery, including the removal of certain kinds of birthmarks. Port-wine stains, reddish purple skin blotches that appear on about three out of every one thousand children, are an example. Such stains can mark any part of the body but are most commonly found on the face and neck. The medical laser is able to remove a port-wine stain for the same reason that a military laser is able to flash a message to a submerged submarine. Both lasers take advantage of the monochromatic quality of laser light, that is, its ability to shine in one specific color. The stain is made up of thousands of tiny malformed blood vessels that have a definite reddish purple color. This color very strongly absorbs a certain shade of green light. In fact, that is why the stain looks red. It absorbs the green and other colors in white light but reflects the red back to peopleââ¬â¢s eyes. To treat the stain, the doctor runs a wide low-power beam of green light across the discolored area. The mass of blood vessels in the stain absorbs the energetic laser light and becomes so hot that it is actually burned away. The surrounding skin is a different color than the stain, so that skin absorbs only small amounts of the beam and remains unburned. (Of course, the burned A doctor uses an argon laser to remove a port-wine stain, a kind of birthmark. Unwanted tissue is burned away while normal skin remains undamaged. areas must heal, and during this process some minor scarring sometimes occurs. ) Laser-Assisted Dentistry Dentistry is another branch of medicine that has benefited tremendously from laser technology. Indeed, lasers have made some people stop dreading a visit to the dentist. No one enjoys having a cavity drilled, of course. It usually requires an anesthetic (a painkiller like novocaine) that causes uncomfortable numbness in the mouth; also, the sound of the drill can be irritating or even sickening to some people. Many dentists now employ an Nd-YAG laser (which uses a crystal for its lasing medium) instead of a drill for most cavities. The laser treatment takes advantage of the simple fact that the material that forms in a cavity is much softer than the enamel (the hard part of a tooth). The laser is set at a power that is just strong enough to eliminate the decayed tissue but not strong enough to harm the enamel. When treating a very deep cavity bleeding sometimes occurs, and the laser beam often seals off blood vessels and stops the bleeding. The most often asked question about treating cavities with lasers is: Does it hurt? The answer is no. Each burst of laser light from a dental laser lasts only thirty-trillionths of a second, much faster than the amount of time a nerve takes to trigger pain. In other words, the beam would have to last 100 million times longer in order to cause any discomfort. So this sort of treatment requires no anesthetic. Advantages of Lasers for Dental Surgery In this excerpt from an article in The Dental Clinics of North America Robert A. Strauss of the Medical College of Virginia mentions some of the advantages of using lasers for oral surgery. Decreased post-operative swelling is characteristic of laser use [for oral surgery]. Decreased swelling allows for increased safety when performing surgery within the airway [the mouth] . . . and increases the range of surgery that oral surgeons can perform safely without fear of airway compromise. This effect allows the surgeon to perform many procedures in an office or outpatient facility that previously would have required hospitalization. . . . Tissue healing and scarring are also improved with the use of the laser. . . . Laser wounds generally heal with minimal scar formation and . . . often can be left unsutured [without stitches], another distinct advantage. Thus the role of laser in medical field is most predominant. How to cite Role of Youth in Eradicating Corruption, Essay examples

Wotson Introduction â⬠¢ One of the forms of multimodal talk is texting â⬠¢ Texting has captivated a whole generation of young people â⬠¢ Texting has become universal, it is practiced all over the world â⬠¢ Texting is done from mobile to mobile, by sending the text to the mobile number. It can also be sent to many at the same time â⬠¢ Texting is thought to be mostly used by the young people and teenagers â⬠¢ The older generations feel that texting has taken the ability of writing and correct spelling to zero, they deplore what texting has done to the English language â⬠¢ Texting is also done as a means of advertising â⬠¢ Large companies text to anyone they can â⬠¢ Doctor surgeries and even schools like the one I study at also use texting to inform patients and parents relative information. â⬠¢ The language of texting has advanced so much since it had started â⬠¢ There are so many ways to text to each other Paragraph 1 â⬠¢ People have found innovative ways of texting with using rebus abbreviation, this is where a name or a word is represented by a picture or pictures suggesting its syllables â⬠¢ They are like puzzles â⬠¢ Punctuation marks and brackets are used to show emotions. We can see this in transcript 1. ðŸâ¢â seen upright they mean nothing but look at them sideways and it is a smiling face â⬠¢ Other symbols and numbers are used like , @, 4, 8. Paragraph 2 â⬠¢ The use of abbreviated and shortened forms of words saves time in texting and also shortens texts to keep mobile bills at a minimum, as seen in transcript 2. People are so fast at texting in abbreviations that the mind boggles at the speed of their thumbs â⬠¢ There is efficiency in the way letters are used, and texters shorten words to a minimum. Paragraph 3 â⬠¢ Inotation is defined as the tone or pitch of the voice in speaking or the way a person is speaking like conveying anger, liveliness, being shy. â⬠¢ Inotation cannot really be well conveyed in texting. â⬠¢ The messages loose the true meaning of the sender like shown in transcript 3. â⬠¢ Sometimes miscommunication happens and feelings are hurt. â⬠¢ It is hard to explain what you are really feeling through texting. When we communicate body language and tone of voice play an important role. â⬠¢ When we try intonating in a text the other person may read something different in the explanation marks you have sent. â⬠¢ Sometimes Imitation in the text can read a double meaning. Paragraph 4 â⬠¢ The use of non standard words in the texting world has become so popular that almost everyone who texts knows the meanings of the abbreviated words. â⬠¢ Also dialect of different places is making its way into texting. â⬠¢ Like we see words such as lush or mint being used in other regions of England. For example in Manchester ââ¬Å"mintâ⬠means really good and ââ¬Å"mardyâ⬠means moody , in whales ââ¬Å"lushâ⬠means very nice and in London ââ¬Å"pukkaâ⬠means very good. â⬠¢ We see their uses in transcript 4. â⬠¢ The use of slang in texting has also found a place in texting. â⬠¢ To a person who dose not text, the language use must seem foreign. Paragraph 5 â⬠¢ In non standard words a new form of communication has emerged. â⬠¢ For example a text pal is a person that you never talk to or see, but you ju7st text to like a pen pal. Another example is saying things like ââ¬Å"text of the devilâ⬠a version of speak of the devil. The way we would use these new words can be seen in transcript 5. â⬠¢ A whole new dictionary would have to written just to accommodate all the new words that have sprung up in this new texting age. Paragraph 6 â⬠¢ The use of incomplete sentences or the use of phrases instead of using the proper grammatical sentences is common in texting, â⬠¢ When you use incomplete sentences you fail to express the total meaning. â⬠¢ Shortening of sentence or use of phrases is fine while texting because of maybe, the lack of time or space texting like in transcript 6. â⬠¢ Phrases also are a part of this new language and most teenagers will know hundreds of them. It is like a second language for them. â⬠¢ These are a few popular phrases in texting; BFF (best friends forever), FYI (for your information), IDC (I donââ¬â¢t care), JC (just chilling), GAL (get a life). â⬠¢ We can see how to use a phrase in transcript 7. Paragraph 7 â⬠¢ I think one of the similarities between texting and speech is that we text the way we speak. â⬠¢ We text the words the way they sound, not like the way they are spelt in the dictionary. â⬠¢ We text phonetically. â⬠¢ Spelling goes out of the window. â⬠¢ The content of the text that is written is a different matter. We see that many words are taken out of the sentences to mak e them shorter and if we read these shortened text messages out loud we would sound like cavemen in cartoons or like Tarzan saying,â⬠me Tarzan, you Jane. â⬠¢ Even I say to my mum SOZ (sorry), LOL (laugh out loud) and CBA (canââ¬â¢t be asked). â⬠¢ My mum is always shouting at me to speak proper English Paragraph 8 â⬠¢ When it comes to actual writing students are using text language instead of proper English in their studies â⬠¢ This is creating problems in our schools, colleges and the workplace â⬠¢ Texting is a distraction and stops you from paying attention to what is happening around you. Students are found texting in classes instead of paying attention of what is happening in the classroom. â⬠¢ Texting has its negatives but it also has its positives. â⬠¢ It keeps people connected to each other. â⬠¢ Testers are always updating each other of what is going on there and then. â⬠¢ Sometimes it is better to quietly text than to talk in a public place and disturb others. â⬠¢ For every new technology there will always be positives and negatives. â⬠¢ I think there is always a middle way in which we can use texting and not go to the extreme.
