Role of Youth in Eradicating Corruption Essay Example Role of Youth in Eradicating Corruption Essay Role of Youth in Eradicating Corruption Essay Laser and its medical applications Presented by S. vignesh J. sabastian The Advent of the Laser Scalpel 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. 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 patients heart muscle to increase the organs 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 surgery is very he lpful when a doctor must operate on a tiny area that is surrounded by healthy tissue or organs. It should be pointed out that the laser scalpel 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 reach- areas on the bodys 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 peoples 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 doctors 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 patients 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 breakthroughs fo r 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. First, the laser is very useful in removing extraneous blood vessels that can form on the retina- the 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 doctors office. The laser can also repair a detached retina- one 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 weld 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 eyes 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 doctors 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 can pass harmlessl y 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 weld or seal the detached area of the retina back against the wall of the eyeball. The patients 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 peoples 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.

Timeline and Definition of the Nazca Civilization

Timeline and Definition of the Nazca Civilization The Nasca (sometimes spelled Nazca outside of archaeological texts) Early Intermediate Period [EIP] civilization was located in the Nazca region as defined by the Ica and Grande river drainages, on the southern coast of Peru between about AD 1-750. Chronology The following dates are from Unkel et al. (2012). All dates are calibrated radiocarbon dates. Late Nasca AD 440-640Middle Nasca AD 300-440Early Nasca AD 80-300Initial Nasca   260 BC-80 ADLate Paracas 300 BC-100 Scholars perceive the Nasca as arising out of the Paracas culture, rather than an in-migration of people from another place. The early Nasca culture arose as a loosely-affiliated group of rural villages with self-sufficient subsistence based on corn agriculture. The villages had a distinctive art style, specific rituals, and burial customs. Cahuachi, an important Nasca ceremonial center, was built and became a focus of feasting and ceremonial activities. The Middle Nasca period saw many changes, perhaps brought about by a long drought. Settlement patterns and subsistence and irrigation practices changed, and Cahuachi became less important. By this time, the Nasca were a loose confederacy of chiefdomsnot with a centralized government, but rather autonomous settlements that regularly convened for rituals. By the Late Nasca period, increasing social complexity and warfare led to the movement of people away from the rural farmsteads and into a few larger sites. Culture The Nasca are known for their elaborate textile and ceramic art, including an elaborate mortuary ritual associated with warfare and the taking of trophy heads. More than 150 trophy heads have been identified at Nazca sites, and there are examples of burials of headless bodies, and burials of grave goods without human remains. Gold metallurgy in early Nasca times is comparable to Paracas culture: consisting of low-tech cold-hammered art objects. Some slag sites from copper smelting and other evidence suggest that by the late phase (Late Intermediate Period) the Nasca increased their technological knowledge. The Nasca region is an arid one, and the Nazca developed a sophisticated irrigation system that aided in their survival for so may centuries. The Nazca Lines The Nasca are probably best known to the public for the Nazca Lines, geometric lines and animal shapes etched into the desert plain by the members of this civilization. The Nazca lines were first intensively studied by the German mathemetician Maria Reiche and have been the focus of many silly theories concerning alien landing places. Recent investigations at Nasca include the Project Nasca/Palpa, a photogrammetric study from the Deutschen Archologischen Instituts and Instituto Andino de Estudios Arqueolà ³gicos, using modern GIS methods to record the geoglyphs digitally.​ More on the Nazca: Nazca Lines, Ica Region pottery vessel Archaeological Sites: Cahuachi, Cauchilla, La Muna, Saramarca, Mollake Grande, Primavera, Montegrande, Marcaya, Sources Conlee, Christina A. 2007 Decapitation and Rebirth: A Headless Burial from Nasca, Peru.  Current Anthropology  48(3):438-453.

Changes in Maro environment Essay Example | Topics and Well Written Essays - 500 words

Changes in Maro environment - Essay Example Wal-Mart in Mexico was impacted due to the 1994 currency crisis. Due to currency crisis, the interest rate was decreased in the Unites States as a result of which the amount of net capital inflows in Mexico was adversely impacted. With this macroeconomic variables’ impact, Wal-Mart’s credit position was affected which brought the firm in unstable position through increased level of cost and decreased productivity. The case of Wal-Mart in Mexico is a practical implication of the political decisions’ impact, which is a macroeconomic factor, upon the operations of a firm (Oxelheim, Wihlborg, & Zhang, 2009). The similarity between the strategies adopted by McDonald’s in China and Wal-Mart in Mexico is that both the firm strived to come out of certain adverse consequences of the macro environment and succeed in the respective markets. The difference between the strategies is that McDonald’s followed ‘customer driven’ strategy whereas Wal-Mart followed ‘competition driven’ strategy. This is because McDonald’s focused on implementing various ways of winning customers’ belief, while on the other hand, Wal-Mart concentrated on gaining competitive advantage through adoption of various innovative strategies such as opening up of banks in its stores. In the case of McDonald’s expansion strategy in China, the Chinese governmental policies towards foreign companies attempting to acquire China’s natural resources impacted upon the firm’s cost during entering the market as they had to make use of channels for avoiding this entry barrier. Utilization of channels accompanied extra cost for the company and also in certain cases, the firm had to compromise with its business structure for reducing the entry barriers. Again the case of Wal-Mart’s expansion strategy in Mexico had been highly impacted due to the trading situations between Mexico and the US resulting in various

Fluid mechanics Assignment Example | Topics and Well Written Essays - 2000 words

Fluid mechanics - Assignment Example Introduction When a fluid undergoes motion, there are certain laws it must satisfy. Two of the basic laws pertain to the conservation laws for mass and energy. While the conservation of mass leads to Continuity Equation, conservation of energy gives us Bernoulli’s Principle. (1) Continuity Equation: the amount of fluid volume per unit time must remain constant as the fluid cannot be compressed (no density variation) and the mass flowing in to a certain area per unit time must always be same to that going out from that area in exactly the same time. Thus, leading to the important equation Q = A1 ? u1 = A2 ? u2 .....(1) where A1 and u1 are the cross-sectional area and fluid velocity respectively at the location ‘1’; and A2 and u2 are those at ‘2’ along the Venturi Tube shown below. (2) Bernoulli’s Equation: similarly, when we take into account the conservation of total energy of the water in the Tube, which happens to be one of the most fundament al conservation principles in Physics, we obtain the Bernoulli’s equation. ... ic Head† or â€Å"Pressure Head†, denoting the energy due to the fluid pressure; the 2nd term defined as â€Å"Velocity Head†, denoting the kinetic energy; and the 3rd term named as â€Å"Potential Head†, denoting potential energy, combine together to give the total energy or â€Å"Head† of the fluid in motion. Apparatus Used (1) Venturi Tube or Venturimeter (2) Stopwatch (3) Graduated Beaker 1 2 3 4 5 6 7 8 9 10 11 Venturimeter or Venturi Tube Methodology Step 1: Known volume of water (10 litres in the first case) is allowed to flow in through the inlet, located at position marked as ‘1’ Step 2: when the water flows through the Venturi Tube and goes out through the valve at ‘11’, it is collected in the graduated beaker and the volume is noted down along with the total time taken to travel through the Tube. Subsequently, Q, the Volumetric Flow Rate is measured using the Eqn. (1) Step 3: simultaneously, the heights of the wat er columns in each of the 11 capillary tubes connected to the Venturimeter at 11 different locations are also observed carefully and put the relevant column in the Observation Table 1 below Step 4: the Velocity Head and Pressure Head as given by Eqn. (2) are also calculated for different fluid velocities at different locations, and the values are tabulated in Columns 6 & 8 respectively Step 5: finally, the total energy or Head of the fluid is measured just by adding the Velocity Head and the Pressure Head since the Potential Head remains unchanged Step 6: all the 5 steps mentioned above are repeated for 20 litres and 25 litres and the measurements are recorded in Tables 2 & 3 Step 7: bar diagrams are plotted for Evh, the Velocity Head, against the Tube Locations. Similarly, another graph is plotted for Esh, the Static Head, Vs the Tube

Parsimony ? The Fourth Substance :: essays research papers

<a href="http://www.geocities.com/vaksam/">Sam Vaknin's Psychology, Philosophy, Economics and Foreign Affairs Web Sites Occasionalism is a variation upon Cartesian metaphysics. The latter is the most notorious case of dualism (mind and body, for instance). The mind is a â€Å"mental substance†. The body – a â€Å"material substance†. What permits the complex interactions which happen between these two disparate â€Å"substances†? The â€Å"unextended mind† and the â€Å"extended body† surely cannot interact without a mediating agency, God. The appearance is that of direct interaction but this is an illusion maintained by Him. He moves the body when the mind is willing and places ideas in the mind when the body comes across other bodies. Descartes postulated that the mind is an active, unextended, thought while the body is a passive, unthinking extension. The First Substance and the Second Substance combine to form the Third Substance, Man. God – the Fourth, uncreated Substance – facilitates the direct interaction among the two within the third. F oucher raised the question: how can God – a mental substance – interact with a material substance, the body. The answer offered was that God created the body (probably so that He will be able to interact with it). Leibnitz carried this further: his Monads, the units of reality, do not really react and interact. They just seem to be doing so because God created them with a pre-established harmony. The constant divine mediation was, thus, reduced to a one-time act of creation. This was considered to be both a logical result of occasionalism and its refutation by a reductio ad absurdum argument. But, was the fourth substance necessary at all? Could not an explanation to all the known facts be provided without it? The ratio between the number of known facts (the outcomes of observations) and the number of theory elements and entities employed in order to explain them – is the parsimony ratio. Every newly discovered fact either reinforces the existing worldview – or forces the introduction of a new one, through a â€Å"crisis† or a â€Å"revolution† (a â€Å"paradigm shift† in Kuhn’s abandoned phrase). The new worldview need not necessarily be more parsimonious. It could be that a single new fact precipitates the introduction of a dozen new theoretical entities, axioms and functions (curves between data points). The very delineation of the field of study serves to limit the number of facts, which could exercise such an influence upon the existing worldview and still be considered pertinent.

Children of Men Film Essay

Children of Men is a thought provoking film directed by Alfonso Cuaron which explored the possibility of hope in the face of overwhelming despair. The film has a fearful, chaotic mood within the setting of a dystopian world in London 2027. Visual and verbal techniques such as camera techniques, diegetic and non-diegetic sound, and symbolism were effectively used across the film. Cuaron used these techniques to show the audience that the search for self preservation demonstrates ignorance for the good of humanity. However, Even though morality is lost when the world deteriorates, hope can still be found in mankind’s bleakest moments; as the darkness of humanity cannot exist without the light, which shows that it’s future. In a world where the deterioration of humanity has caused destruction to a society, people tried to hold on to the last bit of hope while having to survive in the abyss of despair. An example is the diegetic sound of a news reporter on TV in a coffee shop, reporting the tragic death of Baby Diego. â€Å"The world was stunned today by the death of Diego Ricardo. Diego Ricardo, the youngest person on the planet was 18 years, 4 months, 20 days, 16 hours and 8 minutes old†. By stating Diego’s age to the exact minute, the reporter emphasizes his significance as he was the youngest person alive after 18 years of infertility. Cuaron used this technique to enlarge the great grief and devastation that the rest of the world suffers due to the tragic event. Making the audience see that the fragile fate of humanity has been dealt a shattering blow, it looks as if mankind’s last flicker of hope has been extinguished along with Diego’s death, and the species of human ra ce will perish. Another successful sound effect used by Cuaron was tinnitus. This verbal technique is a ringing sound one hears when ears are damaged after loud noises, and it was used after the bomb explosion in the coffee shop. The tinnitus is sympathizing as the ringing sound is heard by Theo as well as the audience, relating the audience to Theo’s experience and making them more involved in the film. This technique is symbolic as Cuaron expresses that the dull reality prevents us from hearing our surroundings, foreshadowing Theo’s numb emotion and reaction towards the situation. Cuaron used this technique to highlight the fearful and chaotic environment, constantly reminding audience the death and despair Theo experienced. The film is very much relatable to our society as the destructed world in the film does not seem so distant from our own. Cuaron makes the audience realize that if we are not careful and take care of crucial issues, it is possible that similar situations in the f ilm could become our future. The frequent use of visual techniques by Cuaron also developed the despairing environment in the film. One example is a reverse angle shot of Theo and the suicide kit Quietus at Jasper’s house. The suicide kit was handed out by the government, showing that even the government had no intention of dealing with existing issues and preferred the easy way out. The white and pale blue colour of Quietus symbolizes peacefulness, showing that instead of keep living in the abyss of desperation, people would rather die to escape the corrupted world. This is appalling to the audiences as Cuaron makes them realize that life was no longer important in the gloomy society of the film. Without hope and faith for the future, the only control people had when facing despair was the option of suicide. Another example that develops the idea of despair is the use of a mid shot out of the bus to Bexhill. The mid shot shows refuges caught by immigration police; locked up in cages, beaten and shot. This technique reinforces audience to see the visual allusions created by Cuaron, as the situation is somewhat similar to the Nazi roundups. With the use of this visual technique, Cuaron is able to show us a world where government control has become so powerful that humanity no longer exists, and the inhuman treatments that the immigrants received were not noticed or cared by British citizens. The refugees were hidden away from society and irresponsibly dealt with so the issue doesn’t have to be taken care of. Cuaron’s purpose is for the audience to see that society tends to, and is, ignoring larger issues which cause discomfort simply because it is the easy way out. However, we all have the responsibility to help each other out and solve existing issues within the community, in order to bring right and justice to the society. There are also hopeful situations throughout the film. This can be explored by the use of non diegetic music â€Å"Fragments of a Prayer† as Kee symbolically revealed her pregnancy to Theo in a barn. The music was implemented several times in the film during moments of hope. The holy shrill voices of the song manipulates viewer to believe that there is always hope as Kee undid her clothes to show her miraculous pregnancy. Theo’s dialogue of â€Å"Jesus Christ† after he saw Kee’s belly symbolically brings realization of biblical allusion to the audience. Surrounded by sheep and cows, Kee was the connotation of Virgin Mary. The similarities allow viewer a deeper understanding of how important Kee’s pregnancy was to mankind, in both cases it was the carrier of humanity’s savior that was in undergoing the long journey. Cuaron also used lighting techniques to highlight the unborn baby’s representation of hope midst despair. The chiaroscuro lighting creates a light shade effect during the revelation of the baby. Darkness in the barn emphasized a patch light on Kee’s belly. Her glowing belly seemed radiate shine, making it look angelic. Cuaron successfully used these techniques to tell the audience that Kee’s pregnancy was a brief moment of humanity allowed that existed in a world determined to tear itself apart. A further biblical reference is Theo’s similarities to Jesus. His character is non-violent, despite being surrounded by guns and bombs. While defending and protecting Kee, he never used or carried weapons. Theo was also consistently surrounded by animals, which are used throughout the film as indicators of goodness and trustworthiness. By using these Christianity symbols, Cuaron reveals a cautious faith in humanity in the characterization of Theo as he came to demonstrate man’s best attributes, compassion, self-sacrifice and hope. Another example which develops the ide a of hope is the establishing shot of Kee, the baby and Theo on the boat staggering towards the Ship of Tomorrow to get to the Human Project. The non diegetic music of â€Å"Fragments of a Prayer† was again used, setting ablaze to hope as Kee was getting closer to safety. When Kee questioned whether they were too late, Theo answered â€Å"Trust me, they’ll come back†. This dialogue contrasts with his dialogue earlier in the film â€Å"Why do people believe this crap†¦ Too late the world went to shit†. Cuaron used this contrast to show the change in Theo to which he was no longer numb about the corrupted world and finally found hope and faith for the future. This provides the audience with catharsis, and it is a release from action to allow viewer to believe that everything will get better. Cuaron’s purpose is for the audience to understand that dread and fear can have a damaging effect on society but is also a driving force behind the vital change needed to save our planet. We should always hope but think and act now because the final result is up to us. In conclusion, a variety of visual and verbal techniques were used by Cuaron throughout Children of Men. These techniques created a destructed and gloomy society which allows viewers to seek through the failure of future construction along with the bleak and brilliant of hope and humanity. Revealing how humanity’s nature and glory is essential in order for human race to maintain faith and stay in a balance of compatibility. Challenging viewers to consider the effect of manmade actions on the current world and how it is shaping the future.

The Effects Of Video Games On Children - 1069 Words

There are many addictions in the world, ranging from hard drugs to extreme exercise. Some are life-threatening, while others only affect appearance or lifestyles. Video games aren’t something most people would see as an addiction, but after witnessing it myself, I have done research to learn more about how video games can rule lives. The causes and effects show just how much lives can be altered. One of the main causes of video game addiction is the constant desire to move up in rank. Every player wants to beat the person above them or reach the next level. This gives the player a sudden feeling of accomplishment. Many people want to feel like they have accomplished something in life, whether it be saving someone from death or picking up†¦show more content†¦Video game addiction in people with ADHD is very high because it stimulates them. Video games stimulate their eyes with colors and quick movement, their ears with the loud sounds, their brain with strategies or go als, and their hands with the controller or keyboard. This causes them to hyperfocus and be nearly unable to stop playing. Their constant desire to stimulate their brain may distract them in everyday life. The player may go out to eat with their family or friends and be thinking about a strategy to beat the next level on their game, or even be playing on their phone. They might get low grades in school because they spend more time gaming than doing homework and they might not be able to focus in class due to thinking about their new favorite game. They might not even care about their grades because their game in an alternate universe seems more important. This can cause a sense of failure and disappointment when teachers or parents get upset about the grades that are being received. Feeling a need to escape can cause a person to cling to an alternate universe. If a person has anxiety, depression, or low self-esteem, video gaming can make them forget about those things for a temporar y period of time. In a game, the player can create their character to be whoever they want to be. When they look at the screen and see who they created, they forget about who they really are.
