Essay A History of Video Game Development - 1889 Words

Video games are an ever-growing franchise that is constantly undergoing change. Ever since the dawn of video games, new consoles, games, developers, and teams have come together, fallen apart, triumphed, and failed. What is it that has allowed some to thrive where others failed? Several different factors have changed and influenced the world of gaming, including the history that is continuously being written, the people who have built the games behind the scenes, and, of course, the actual video games themselves. Numerous video games have been more successful than others, but identifying what components set the successful apart from the unsuccessful is something definitely worth observing. To find an answer to this statement, one†¦show more content†¦1-2). Although, seeing as video games are increasingly popular today, not everyone met as unfortunate of a fate. Today, many could credit this to the video game development corporation known as Atari, which arose in 1972 and continuously flourished until about 1982. In 1972, Atari came out with PONG, the first electronic arcade game, and it was an enormous accomplishment that exploded into what is now called the electronic gaming revolution. As time passed, Atari managed to triumph over its competition time and time again, but that is not to say that each of the failed corporations did not feature something that is used today. In fact, a couple of the failed organizations contributed something original to what is common today. For instance, Fairchild Camera and Instrument creating the first system that could play several different games, rather than just one. Another aforementioned group, RCA, was the first to produce and utilize keypad controllers instead of paddles or joysticks. Ot her consoles that came along, such as Intellivision and Vectrex, sported better graphics than the Atari’s consoles and games, but they still did not manage to gross the amount of money that Atari did because Atari was still on top of collecting all of the most entertaining and enjoyable games of their time. Keep in mind what attracted the masses to video games in the past: fun and addictive gameplay, not how good they looked.

string(47) " that target the neurotransmitter systems \(e\." PD normally affects people over the age of 50. It becomes more common with increasing age. ‘About 5 in 1,000 people in their 60s and about 40 in 1,000 people in their 80s have PD’1. We will write a custom essay sample on Parkinsons Disease or any similar topic only for you Order Now It affects both men and women but is a little more common in men. PD is not usually inherited, and can affect anyone. However, genetic factors may be important in the small number of people who develop the disease before the age of 50. PD therefore affects a lot of people in the UK and I have chosen this topic so I have a greater understanding of what they go through and how we can help those affected. Background: Biology of Parkinson’s disease? Parkinson’s disease is a chronic disorder of part of the brain called the substantia nigra. It mainly affects the way the brain co-ordinates the movements of the muscles in various parts of the body. This area of the brain sends messages down nerves in the spinal cord to help control the muscles of the body. Messages are passed between brain cells, nerves and muscles by chemicals called neurotransmitters. Dopamine is the main neurotransmitter that is made by the brain cells in the substantia nigra1.

The cause is unknown. Over time, more and more cells become damaged and die. The more cells that are damaged the less dopamine is produced. The reduction of cells and the low level of dopamine in the cells in this part of the brain causes nerve messages to the muscles to become slowed and abnormal1. In the long term PD will ultimately lead to death. Causes We are still unsure of the causes of PD but here are the most likely and most talked about suggestions: 1. The hereditary form of PD occurs in fifteen per cent of cases2. The genes affected help clear nerve cells of excess proteins. Scientists are not sure but it is thought that when the ‘production process for protein manufacture breaks down, little clumps of ill-formed proteins begin to accumulate in cell’ 17, causing cell death. Tests carried out on rats using rotenone imply that pesticides and toxins may lead to PD. The rats experienced shaking and a loss of muscle control as well as developing Lewy bodies (spherical lumps found in dying brain cells), which are commonly associated with Parkinson’s disease. However, researchers are yet to find evidence for any definitive link to a particular toxin or drug in humans. 2. There seems to be a link between variants of the mitochondrial genes and PD. The Parkinson’s Disease Research Agenda states that â€Å"mitochondrial dysfunction has numerous consequences, including energetic failure, generation of reactive oxygen species, disregulation of calcium homeostasis and induction of apoptosis, each of which may be important in Parkinson’s disease†3. 3. High concentrations of free-radicals in the body and a lack of antioxidants. Free radicals damage cells and if too many dopamine-producing cells were damaged then this could lead to PD. Antioxidants prevent the production of free radicals and repair damage done by them. Symptoms and effects There is no easy test to diagnose PD, so it is diagnosed by ruling out other diseases and looking for the classic symptoms: * Slowness of movement (bradykinesia)1. It will become more of an effort to walk or get out bed. People may just think they are getting old and it is not till other symptoms develop that you may think about PD. * Stiffness of muscles (rigidity) and muscles may feel tenser. Also, your arms do not tend to swing as much when you walk. * Shaking (tremor) is common, but does not always occur. It normally affects the fingers, thumbs, hands, and arms, but can affect other parts of the body. It is most noticeable when you are resting and may become worse when you are anxious or emotional. It’s generally less obvious when you use your hand to do something such as picking up an object or writing. Symptoms will tend to get worse and worse and as the disease develops. Some other symptoms may develop due to problems with the way affected brain cells and nerves control the muscles. These include: * Fewer facial expressions such as smiling or frowning. Less blinking. * Difficulty with fine movements such as tying shoe laces or buttoning shirts. * Difficulty with writing (handwriting tends to become smaller), balance and posture and swallowing. * Speech may become slow and monotonous. * Tiredness aches and pains. As PD gets really bad, symptoms such as the following might develop, dependant on the individual: * Constipation- †PD prevents the proper transmission of the neurological messages that tell the rectal sphincter muscles to open†7 * Hallucinations (seeing, hearing or smelling things that are not real) * Sweating- PD can affect the autonomic nervous system8 that controls the autonomic functions (functions done automatically by the brain and body without conscious thought) such as sweating, breathing etc. * Difficulties with sleeping * Weight loss- there is a generally decreased appetite associated with PD. This may largely be due to swallowing difficulties and other gastrointestinal disturbances8 * Pain * Depression Anxiety- anxiety disorders occur in up to 40% of patients with Parkinson’s disease (PD)9. The article states †Current evidence suggests that anxiety may not be a psychological reaction to the illness but rather may be linked to specific neurobiological processes accompanying PD.† * Problems with controlling impulses (for example compulsive eating, shopping or gambling) Most people will only suffer form a few of these symptoms and which ones will get worse and the speed at which they get worse varies hugely from person to person. Some rare brain diseases can have very similar symptoms in which case a specialist brain scan can often be used to distinguish between them. The Treatments At the moment there is no cure for PD and most treatments simply have the job of relieving symptoms. 1. Drugs Intro: there are two main types of drug used in PD treatment. Firstly, drugs that target the neurotransmitter systems (e. You read "Parkinsons Disease" in category "Papers"g. dopamine) or secondly drugs that are designed to interfere with steps in the neurodegenerative processes (they may aim to sustain nerve cells or tackle the issue of free radicals). Drugs are cheap and effective, especially in relieving symptoms but show little potential as a full cure to the disease. Most also need to be taken daily for the remainder of a patients lifetime. Many drugs may have minor side affects. Some side affects have social impacts such as mood swings or may not allow the user to fly or travel to certain places. Dopaminergic Agents- use to activate the production or use of Dopamine. Levodopa- is an amino acid that is converted in the brain into dopamine. According to the WE MOVE website10 ‘Levodopa was introduced as a PD therapy in the 1960s, and remains the most effective therapy for motor symptoms’ although there are many drugs that do a similar job such as Rasagiline. It reduces the effect of and helps control the symptoms of PD. Like most amino acids levodopa is absorbed into the blood stream through the wall of the intestines. Amino acids require a ‘transporter’ to transfer them across the membrane of the intestines and into the blood stream. These transporters can only work at a certain rate and so diet is important. To much dietary protein can slow the transport of levodopa into the blood stream meaning the dose may be ineffective. Alternatively to avoid the competition with other amino acids, doses should be taken between meals. Levodopa has to cross from the blood stream into the brain using the same transport system again, making diet and timing doubly important. MAO-B Inhibitors- slow the breakdown of dopamine in the brain and aim to prevent or slow the death of neurons. ‘MAO is responsible for the mitochondrial metabolism of monoamine neurotransmitters, including dopamine and serotonin.’11 Ethical implications Some of the many ethical issues revolve around the decision to move from testing on artificial tissue (often grown from stem cells, which may in the future replace animal testing altogether. Stem cells, however create there own ethical issues) to animals, and further on the line, of animal testing to trails on human patients. The graph below shows the stages involved in developing a new drug and is taken from the MSD website (21/3/10): (http://www.msd.com.hk/health_info/drug_education/e_ddp_introduction.html) Animal testing is very closely regulated in the UK however many, often false, accusations of animal abuse have lead to darkened perceptions of animal testing in the public eye. Animal abuse is definitely a reality but ‘improved transparency, accountability and regulations’12 should reduce it happening and make sure those responsible are prosecuted. Unlike humans, animals are unable to consent to testing. It is forced upon them and often involves a certain amount of pain, stress, suffering and discomfort. Researchers will try to reduce this, possibly using anaesthetics although this can often interfere with the drug being tested so the animal may have to suffer the full amount of pain. Unfortunately, in PD, a number of animals are tested on normally starting with mice or rats before moving on to monkeys and finally human trails. Some people believe that animals like monkeys and most primates shouldn’t be experimented upon as they aren’t in the same plentiful supply that rats and mice are in, nor are they considered pests. However, for potentially dangerous drugs it is essential animals with a similar genetic make up (primates) are tested on to greatly reduce the risks in human clinical trails. Economics of drugs in PD As shown in figure 1.2 drug development requires a huge amount of research and testing and can take more than 10 years before a useable drug is created. This obviously requires a huge amount of investment and general drug development costs vary between 500 and 2,000 million dollars. R;D is often done by independent companies or government organizations. Most companies or organizations will link with universities to share information and facilities and hopefully quicken to process of discovering a new drug. ‘After approval, pharmaceutical companies have a short period of exclusivity before patents expire and other companies can market the same drugs as generics. This time is used to recoup the massive investment required to develop and launch a new drug. However, the companies must also continue to test their drugs and monitor the feedback from healthcare professionals in order to identify undiscovered side effects, risk factors and interactions.’13 Drug companies are some of the most profitable industries in the world and although a large amount of money is needed in research and development (R;D) only 1 in 5 dollars made is then invested in further research. Many companies spent nearly twice as much money on advertising and marketing than R;D and demand is so much higher than it needs to be that companies can afford to boost prices to maximise profit. Luckily with PD this becomes less of a problem as people are unlikely take and therefore buy drugs that are meant for PD when they don’t actually need it. This is because the symptoms tend to be quite clear and drugs like levodopa are not readily available unless prescribed. Benefits to humans Drugs can have a massive impact on people suffering from PD and they aim to do a number of things: 1) Improve standards of living- by reducing the affects of PD and slowing the process of neurodegeneration it should allow the person suffering to do basic things (such as tying shoelaces, writing etc) more easily and for longer before they require full time medical care. This allows them to be more independent. 2) The use of drugs such as levodopa, in the long term, will reduce the affects of symptoms such as tiredness, aches and pains. Painkillers like amantadine will also be used for more short term relieve along side drugs like levodopa. This will simply make life less painful for a PD patient. 3) Drugs are the most well know and reliable of PD treatments. This reduces the risks of any unknowns or mistakes and far fewer mistakes will be made than in using other treatments. Risks to humans 1) Unfortunately Nausea and vomiting are common side effects of using levodopa that are due to the building up of dopamine in the bloodstream. The most serious and severe effect of this treatment is dyskinesias. ‘Dyskinesias are uncontrolled movements, including writhing, twitching, and shaking. Dyskinesias result from the combination of long-term levodopa use and continued neurodegeneration. They typically begin to develop in milder forms after 3 to 5 years of treatment, but are more severe after 5 to 10 years of treatment.’10 2) There is always risk of allergies when using drugs and for some unfortunate people drugs may do more damage than good. 3) Side affects of drugs vary from person to person and it is impossible to know beforehand how a certain drug will affect an individual. For some, side affects may be far worse than for others. 4) Dosages need to be got right and it is a common problem that people take to little and don’t get the full benefit of the drug or take to much and suffer more/worse side affects. A massive overdose will likely lead to death. Alternative Cures? 2. Gene therapy- is still in early research stages and it is likely to be a while before this technique is actually used on humans. Like stem cells it has exciting potential to provide a future cure and avoid the ethical issues associated with stem cells. How it works? Gene therapy aims to introduce new and functioning genetic material into cells that have abnormal genes that are causing proteins (in the case of PD, dopamine) not to be created or created faulty. The genetic material can normally be inserted into the cells using viruses. ‘Some types of virus, such as retroviruses, integrate their genetic material (including the new gene) into a chromosome in the human cell. Other viruses, such as adenoviruses, introduce their DNA into the nucleus of the cell, but the DNA is not integrated into a chromosome.’13There is still much development needed as scientists are still unable to target specific cells and there is the potential threat of virus mutation which may cause even further problems. There is also major worry about the potential for gene therapy to be used to improve basic human traits such as height, intelligence etc. People could simply choice characteristics and this in many people’s eyes could be used for the wrong reason. For example, this may be used to give some athletes a major advantage over others or possibly creating super humans. 3. Stem Cells I think stem cells have shown exciting potential and will hopefully provide a full time future cure for the disease. How they work? Stem cells are unspecialised cells that have the ability to develop into highly specialised cells like nerve cells. They can also self-renew, which means they are capable of replenishing themselves for long periods of time by dividing4. For Parkinson’s disease it is hoped that large numbers of the brain cells that produce dopamine can be produced and inserted, through transplantation, into a patient’s brain. Therefore, nerve messages to all parts of the body will be normal again. However, stem cells not been successfully used to cure PD yet and there are many problems facing researchers. Therefore stem cells are relatively useless for PD at the moment but may be able to provide an easy and affective cure in the future. Problems with the types of Stem cells There are three main types of stem cells: 1. Adult stem cells can come from Skin, Bone marrow, Brain, Blood vessels, Liver and Skeletal muscle. However, adult stem cells are found in such small quantities it is difficult to identify and isolate them in viable numbers. Because adult stem cells aren’t as ‘young’ as embryonic stem cells, they contain more DNA abnormalities acquired with age4. These can be caused by the environment, toxins or errors in DNA replication. Adult stem cells have limited potential because unlike embryonic stem cells they can not differentiate into any specialised cell in the body. 2. Cord blood cells are normally found in the umbilical cord and placenta after the cord is cut. One problem is the lack of cells obtained and these may not be enough relative to a patient’s size. Cord blood cells generally take longer to grow, therefore completion of therapy will take longer. It obviously requires a pregnant woman to donate the cells. 3. Embryonic stem cells are found in human embryos and have a seemingly unlimited potential to develop into any cell in the human body. However they are surrounded by a number of ethical issues. Many people and especially religious group condemn the use of embryonic stem cells as they believe it is destroying a life. They believe it is immoral to save a life at the expense of another. However new developments in stem cells research means that Totipotent* stem cells can now be collected without the loss of embryo life: Somatic cell nuclear transfer (SCNT) – nucleus is removed from a somatic cell and is then implanted into a donor egg that has had its nucleus removed6. It divides just as normal before forming an embryo. Cells from the inner cell mass are extracted and cultured to provide embryonic stem cells but the technique destroys the embryo. Although the embryo is destroyed it is a created clone and so may not be considered the loss of new, individual life. Altered nuclear transfer (ANT), however, prevents an embryo from actually being created. The nucleus of the somatic cell is altered, or genetically reprogrammed, before being transferred into the egg. The alteration consequence is that the somatic cell DNA still produces stem cells but does not generate an embryo. Blastomere Extraction is performed on a two-day old embryo, following the division of the fertilized egg into eight blastomeres (cells). One blastomere is removed and can be triggered to divide and the resulting stem cells could still be used for research and disease treatment. The embryo, ‘now with only seven blastomeres can still be implanted into the mother and assuming no defect has been found these embryos will still grow into healthy babies’4. 1.

Acid Rain (870 words) Essay Example For Students

Acid Rain (870 words) Essay Acid RainModern society is becoming overwhelmed with great amounts of pollution fromcars, factories and an overabundance of garbage. The immense amounts of sulphurdioxide emitted into the air causes high levels of acid in the atmosphere. Whenthis sulphuric acid is absorbed into moisture in the air, poignant rainfalls canbe damaging to the external environment. Acid rain is destroying the world=slakes, air and ecosystem. Acid rain is killing lakes and decreasing the numberof inhabitants in these fresh water bodies. Acid rain causes an ample deductionin the pH levels in the water. At a neutral level the pH in water should beclose to seven, yet in these acidic water bodies the pH levels can be as low asfour. These pH levels of four contain more than ten percent acids than that ofnormal rain and one thousand times more acid than neutral water. Each decade thepH levels of lakes around Ontario have become ten times more acidic. The highacid levels contained in lakes also causes a decrease in the number of fishdwelling in these lakes. Also Aacid produces chemical changes in the blood ofthe fish, and their basic body metabolism is (Howard Perley,1980, p. 24), and can cause deformities in these inhabitants. They have twistedand arched backbones, flattened heads and strangely curved tails. In pH levelsof four there is little left in the lakes besides rock bass, pumpkinseed andlake herring. Affected fish are also in danger of becoming sterile, which wouldput the species at risk of becoming extinct. As with sulphur dioxide in rain,mercury is also discharged into the water. There is a direct connection betweenthe mercury rich lakes as there is with those with high acidic levels. Thismetal becomes concentrated in the blood and tissues of fish. Acid rain causestraumatic effects in natural lakes and rivers. Acid rain causes air quality todeteriorate. As in water, acid rain causes the pH levels in the air to decrease. The sulphur dioxide, which diffuses into the air, mixes with moisture causingthe pH levels to drop from the normal level. Again, the normal level issomewhere around seven, yet in some acidic air masses the levels can be as lowas three. These lowered pH levels form a photochemical smog in the atmosphere. In the air Anitrogen oxides react with ozone and some hydrocarbons in thepresence of sunlight to form photochemical smog, the kind of yellow-grey hazewhich it literally alive and growing in stagnant air (Howard Perley, 1980, p. 44). This smog carries serious risk for respiratory disease andcrop damage. The photochemical smog is also causing the ozone layer todisintegrate. The ozone layer is becoming a part of this smog, which is causingholes in it. An inordinate amount of sulphur dioxide is let into the air, morethan can be neutralized by nutrients in the air. Decrease in pH levels,photochemical smog and depletion of the ozone layer are some effects of acidrain in the air. The ecosystem is slowly eroding due to the increased amounts ofacid in the soil. Acid in the soil in causing the carbon dioxide respirationprocess to decelerate. In order for plants to go through photosynthesis, theyneed carbon dioxide. When acid in the soil causing this soil respiration to slowdown, in turn it ca uses the photosynthesis process to slow down. The soil alsoerodes when the pH levels drop. The acidic levels of the soil cause nutrients inthe soils such as aluminum to break apart and the soil to erode. Soil erosionalso causes a lower production of plants in the ecosystem. In the soil a processof decay Acalled oligotrophication, means that fewer of the ions of acid areneutralized by the depleted biological community so the acid can cause furtherdegeneration of natural processes, which in turn are less capable of combatingthe acid, and so on, in an accelerating (Howard Perley, 1980, p. .u9d1e5ced68fe7c2e78c156bef0b2070c , .u9d1e5ced68fe7c2e78c156bef0b2070c .postImageUrl , .u9d1e5ced68fe7c2e78c156bef0b2070c .centered-text-area { min-height: 80px; position: relative; } .u9d1e5ced68fe7c2e78c156bef0b2070c , .u9d1e5ced68fe7c2e78c156bef0b2070c:hover , .u9d1e5ced68fe7c2e78c156bef0b2070c:visited , .u9d1e5ced68fe7c2e78c156bef0b2070c:active { border:0!important; } .u9d1e5ced68fe7c2e78c156bef0b2070c .clearfix:after { content: ""; display: table; clear: both; } .u9d1e5ced68fe7c2e78c156bef0b2070c { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u9d1e5ced68fe7c2e78c156bef0b2070c:active , .u9d1e5ced68fe7c2e78c156bef0b2070c:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u9d1e5ced68fe7c2e78c156bef0b2070c .centered-text-area { width: 100%; position: relative ; } .u9d1e5ced68fe7c2e78c156bef0b2070c .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u9d1e5ced68fe7c2e78c156bef0b2070c .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u9d1e5ced68fe7c2e78c156bef0b2070c .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u9d1e5ced68fe7c2e78c156bef0b2070c:hover .ctaButton { background-color: #34495E!important; } .u9d1e5ced68fe7c2e78c156bef0b2070c .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u9d1e5ced68fe7c2e78c156bef0b2070c .u9d1e5ced68fe7c2e78c156bef0b2070c-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u9d1e5ced68fe7c2e78c156bef0b2070c:after { content: ""; display: block; clear: both; } READ: A Life of Being Bullied Essay32). Disruption in the life span of trees and plants is also another effect ofacid rain. The acid rain corrodes the thin, waxy layer, which coats and protectsthe leaves letting the acid suffocate the leaves. This can cause an interferencein the plants metabolism and photosynthesis may be altered meaning the leavescannot produce and efficient amount of food which may result in death of theplant. Acid may obtrude fertilization , stunt or kill the growth of seeds andmake them sterile. A second generation would be in danger of not being producedcausing deforestation. Naturally the reduction of plants is causing thebiological food chain to weaken. A s smaller animals and insects feed on theseplants lose their food supply, they may also ensue death. In effect the animalswhich feed off of these animals also ensue a decrease in their supply. In turnhumans may become starved if the acid rain effects increase. Acid rain causesdeath of soil, plants and animals, effecting the ecosystem. Acid rain isbecoming a major problem in our environment today. It is killing our fresh waterlakes and it=s occupants. Also the quality of air is depleting, increasing theamount of smog and pollution in our atmosphere. Once the acid is absorbed in thesoil, this puts the ecosystem in jeopardy of extinction. This is killing plants,animal, and soil, which is the basis of our existence. If this acid rain problemis not dealt with urgently, the natural world may in hazard of demise.

The Life of St. Carlotta

Carlotta was born in ca. 680 A. D. in a small Italian city. Even though at the dawn of the ear known as The Middle Ages, women could have very little effect on the social, political and religious issues in society, St. Carlotta managed to make her contribution to religion and shape people’s ideas of what a true Christian should be.

According to the existing records, she did not know at first what woman talked to her in her dream; but, after going to church and seeing the image of St. Mary, she told her mother that this was the woman from her dream. It is wo rth mentioning that St. Carlotta is often mentioned as a martyr. When she was fifteen, two stigmata opened on the palms of her hands; she had been bearing the stigmata since then till the day when she died. In addition, St. Carlotta also contributed to building a nunnery in the town where she was born. Helping raise the funds to create the nunnery and giving all that she could give, St. Carlotta succeeded in building a rather humble yet charitable nunnery, which is nowadays known as the Nunnery of St. Carlotta. It is hard to overestimate St. Carlotta’s contribution to charity. She always tried to provide the poor and those in need with everything that she could offer. According to what the chronicles of the V Century say, she once saw a woman in ragged clothes and with no shoes on her way to the church. St. Carlotta took her shoes off, gave it to the woman and proceeded to the church barefoot. However, charity is not the only thing to remember about St. Carlotta. Legends say that people witnessed her doing miracles. As one of the legends says, one of the neighborhood boys was at the death’s store because of the disease the symptoms of which can be interpreted nowadays as acute pneumonia. After hearing about the child and his disease, St. Carlotta came to the house of the boy’s parents to save the child. She stood for a while in front of the boy who was lying in bed and then said, â€Å"In three days, you will be cured.† Three days after, the parents realized that the boy was perfectly healthy.Advertising Looking for essay on religion theology?

Le Chene et Le Roseau essays
