Farmers dbq Essay Example for Free
Farmers dbq Essay In the late nineteenth century, twenty years after the Homestead Act, farmers used their land in the western plains to produce both crops and profits. The farmers of this time struggled in the agricultural way of life by facing economic and political obstacles that were impossible to avoid, requiring them to do something about their complaints. Although the farmers had plausible arguments for most of their criticisms, their beliefs of the silver standard and overproduction sometimes could not be backed up. However, farmers continued to struggle between inevitable issues like the currency debate, constant debt and rising costs. The debate over United States currency was a huge obstacle for farmers to overcome because they were in direct relation to the money crisis. In 1890 and 1892 with the Ocala and Omaha Platforms, farmers wanted free and unlimited coinage of silver so they could pay off any debt. A chart showing United States Population and Money in Circulation in 1865-1895 (Document C), shows how after a period of less money in circulation in the 1870s was resolved in the 1880s by the Bland-Allison Act which was later replaced by the Sherman Silver Purchase Act in 1890. Both of these acts were passed in Congress to provide free coinage of silver. The reasoning for the silver standard in the Populist platform in 1892 (Document A) was justified by the same reasoning as William Jennings Bryan in his ââ¬Å"Cross of Goldâ⬠speech. Both describe how the conspiracy that the gold standard is better because England still uses it questions why America became an independent nation. However, the farmers still remained defeated on the currency debate because of the gold bug president gaining control of office. One of the biggest struggles for the farmers was not being able to pay off debt. They borrowed extravagant amounts of money from the bank at high interest rates, but this complaint was reasonable because one could not be a farmer without taking these risks. During Grover Clevelandââ¬â¢s second non-consecutive year in office a horrible four-year depression occurred called the Panic of 1893. This panic was caused by over speculation in the stock market and over expansion of railroads; both of these decisions made by the eastern president, Cleveland. As depicted in A Farmerââ¬â¢s Voice, a Chicago newspaper, (Document D) an eastern leader, Cleveland, takes his western slaves, the farmers, to the courthouse because the farms have been foreclosed. Farm foreclosures, a twenty percent unemployment rate and the cause for Cleveland to return to the gold standard, were effects of the Panic of 1893. Ultimately, this depression added to the unavoidable obstacle of debt.

The Sonnet Essay -- English Literature
The Sonnet Explore aspects of the sonnet tradition through reference to a range of material you have studied The word ââ¬Ësonnetââ¬â¢ comes from the Italian word ââ¬Ësonnettoââ¬â¢ meaning little sound or song. A sonnet is a special type of poem. The sonnet is always 14 lines long and usually expresses the poetsââ¬â¢ personal feelings or thoughts; most often connected with love or death, which are two of the most basic aspects of human existence. The poem generally uses rhyme and metre to organise the poetââ¬â¢s ideas in a formal way. There are several different types of sonnets which all accomplish this in a slightly different style. The Italian or Petrarchan sonnet was originally developed around 1350 by Petrarch, an Italian poet (1304-1374). Petrarch had fallen madly in love with a woman named Laura, but she was a married woman and refused to become his mistress. Petrarch wrote poetry expressing the idea of courtly love and conveying his own misery and his slavery to the love of Laura; a love denied. His verses contain accusations about the fickleness of love, the timeless quality of art and the hopelessness and devotion of eternal love. The Italian sonnet is divided into two sections by two different groups of rhyming sounds. The first eight lines are called the octave. This has two four line units that rhyme in the same way. A b b a, a b b a. The remaining six lines are called the sestet and can have either two or three rhyming sounds arranged in a variety of ways: cdcdcd, cddcdc, cdecde, cdeced, or cdcedc. The poem is clearly divided into two sections by the two differing rhyme groups. The change from one rhyme group to another signifies a change in subject matter. It can also be said that the octet prese... ... years of painââ¬â¢ the word ââ¬Ëlongââ¬â¢ is again repeated to emphasize the time he has been away and the suffering he has experienced as a Black in a ââ¬ËWhiteââ¬â¢ world. The tightness, compression and discipline of the sonnet form does not disguise but rather emphasises his love for Jamaica and his suffering since he left. In conclusion therefore, the sonnet has developed from its traditional form albeit still retaining some of the aspects Petrarch may have once used centuries beforehand such as an octave/sestet structure. It was originally a formal love ââ¬Ësongââ¬â¢ with high ideals and a rigid format. Shakespeare transformed it and made the sonnet more accessible and fun for the common man to enjoy. The sonnet has since evolved further and can be used in a wide variety of forms and for an even wider range of subject matter and can be easily read by audiences world-wide.

Finding the best use for degraded lands in western India Essay
This research paper takes into account different approaches for the use of land in the Western Ghats located on the west coast of India. First of all we will see how this research will use the information that is coming ahead in order to decide which approach should be taken into account. This needs answers and justifications that make an alternative better then the others. Whatever alternative me take upon, first thing first, we need to analyze and enlist both the negative and positive points separately so that we are in a better position in order to make a decision on the behalf of the entire community. Then we need to see weather the alternative that is being implied is cost efficient which means that weather the cost incurred on the implementation of the programme does generate benefit to the community at the same magnitude (Prasad, 2002). A cost benefit analysis is to be donââ¬â¢t in order to see weather the investment on such a programme is beneficial or is a mere waste of money because at this situation, both the people and the government cannot take any risk regarding any such relief programme for which people have been waiting for so long. In continuation to this approach, people of this area are anticipating a long-term solution to their water shortage problem, they want their problem to be solved in the same tenure of the government, without any further time lags, and also they want a solution that they can run themselves even after the administration changes. This is because a system being there and not having adequate resources or authentication to operate is just a mere waste of money and no use to the inhabitants of this village. (Prasad, 2002). The approach that we select through this research paper should be focused on more crop cultivation by the farmers of this area so that they can earn more revenue out of it and hence improve their standard of living. (Prasad, 2002) The area that has been discussed in this research paper is the eastern flank of the Western Ghats in Mahrashtara, India. This area spreads over 180000sq kilometers and is one of the 34 global biologically diversified places. With 30% of all the mammals, plants, fishes and birds in the entire country, the land only comprises of 6% of the total area of the country. This area holds great significance due to its richness in different type of medical that are used in bioengineering research methods and other medicines that we use daily. (Verne, 1999) The area is also known to be one of the richest due to its biodiversity. Moreover this area is also known for having centuries old heritage, values, culture and norms that are still practiced widely among the villagers. Apart from biodiversity, the area has some rich cultural and religious backgrounds which make them stand in the league of highly diverse cultures. They have different rituals norms and values which had led to the creation of separate religious sections which in turn affects decision making at the personal level and hence on the political front. Although, different cultures have brought diversity into the area, the main point over here is to keep them work together so the natural habitat for the endangered species can be saved and the area could be developed in order to protect the biodiversity of the area. (Bull, 2006) The social condition of the area is pathetic as the government officials are notoriously slow in providing the basic services like clean water, schools, hospitals, banks and other recreational services. Lack of the basic amenities of life makes living of the localââ¬â¢s tough which in turn slows down the economic progress of the area. (Bonelle, 2005) Analyzing the topographical situation of the, the area has a mountainous terrain. It receives annual rainfall of around 200-600mm. The rain fall has cycles which vary between two or three months and normally occur between the period of June and September. Lack of water storage facilities makes water a scarce resource because all of its gets dried up in the extreme weather of May and June so there is a dire need of conservation of water. (Bull, 2006) The agriculture sector consists of rice as the only cash crop of this area which is cultivated in the monsoon season starting from June to September. Other crops like grains and pulses are grown after the cash crop is harvested. The fate of the growth of other crops depends on the soil fertility of the left over soil (after being used for sugar cane). Dearth of water coerces farmers to apply expensive fertilizers to keep soil fertile but they are unable to use them due to their exorbitant costs. In turn, these poor farmers have to settle for low quality natural fertilizers like dead leaves, ashes and cow dung which are procured from neighboring areas including other villages and localities. (Verne, 1999) There are three options or alternatives we have to offer to improve the situation of the local inhabitants by lessening their problems and improving their current state of affairs. The alternatives are: 1. A water pipe line to be made in association with the sugar cane mill so cane could be grown in the area. This solution is not a unanimous one but it is suggested by the local politicians who represent the district and federal government. In this way the cultivated sugar cane will earn a handsome amount of revenue to the local population; will bring in water from far flung areas and will also serve the demand of sugar mill. In the long term, it will attract investment for other mills to be set up in the area which would bring in prosperity in the locality as it will create more jobs in the area. 2. Best practices to be adopted from neighboring areas such as Aloke Taluka. Copying the solutions applied to similar problems in other areas shall be beneficial as it would made the conditions of local better, both economically and financially. 3. Lastly, what we can do is just to leave the plan as it is and look for a better venture because no other solution seems to be viable for a problem of this nature. Tackling the last problem first, if no heed is paid to the current problem, it would not harm the county itself except to the cause of biodiversity conservation. These Western Ghats have inhabitants of around 400 ââ¬â 500 households only which not even contribute to a single percent in the GDP of the country. If we just look it from a different prism, we see that there are other lot of issues left to be dealt with so savings mammals and other endangered species is a good idea but not on the expense of already deprived humans who are dying due to insufficient calorie intake and earn less than 1$ a day which does not satisfy their daily needs. We all are aware of the fact that more than half of Indiaââ¬â¢s population lives below the poverty line and have no nutritious food at their disposal. (Lewis, 2004) Apart from this all, doing nothing on providing water to the locality, it would serve as a push factor for villagers to leave this place and migrate to cities where they can earn good living and can live happily. Global warming is also playing its role as the amount of rain fall is has decreased over the time and the future seems to be bleak too as there would hardly be any sufficient rainfall in years to come. (Lewis, 2004). Secondly, copying the viable and practical practices adopted by Aloke Taluka village is something worth to ponder on. The topography of both the villages is more or less the same so the experience gained in one area will certainly help us out in making strategies on the other area. It would make us analyze and learn what their residents have done for the uplift and development of the village. (Verne, 1999) The village of Aloke Taluka has a very fascinating and captivating programme to conserve water. It is something worth analyzing because it shows the desire by the inhabitants of the area to conserve water as it is a scarce resource for them. The project was initiated with the assistance and collaboration of Windsor University of Canada and the cooperation of local government body. The main mission behind this program was to devise strategies which would pool in water from every possible place (mainly in the areas where the water gets wasted), turning it into a huge reservoir (Lewis, 2004) The land on which the agriculture takes place, had never been used before for this purpose so it remained rich and fertile which resulted in extra yield. Terraces were also built on the tops so to prevent water from running off the slopes and to stop soil erosion too. Another interesting way to conserve water was to store water from the roof sheds of the houses. In this way, water was used in kitchens and for gardening purposes. Aquifers were made in a traditional way so water could be stored in it. (Lewis, 2004)Various other contour bunds, damns and nalla bunds were built with the traditional designing and low excavations include ponds and trenches. These trenches were made at 90 degree to the slop of the hills to stop the runoff water and the rich fertile soil from the surface. Waste from farms was taken to field to make soil fertile. It mostly included cow dung and dead leaves. The elder generation of the village has also set up a committee in the area where meetings are held on the regular basis to talk about and converse things related to the farming practices. (Lewis, 2004). They believe that in the order they carried out their farming practices were far better than todayââ¬â¢s as it yielded good results. These ââ¬Ënitty grittyââ¬â¢ and tips full of wisdom can only be found in the talk with the elderly men, can not be found in books. They train and coach their fellow farmers who always get something important to learn from them related to the field of farming. To give an example, there is a tree which is admired, valued and honored by the local community. On snooping it further, it was found that that type of a tree always grows in those places where table is closer to the surface, so the land can be dug out to bring out water easily. This research helped a lot as it uncovered many wells and springs located in the area. The main advantage of this knowledge is that it makes researchers think for more sound and viable solutions. It makes them consider natural fertilizers available in the area like cow dung, burned leaves, ashes of left crop etc. (Lewis, 2004)The awareness of using clean water for the fields and live stocks brought many benefits for the village. Before its knowledge people were of the view that they can come with good amount of yield with any kind of water, whether it is dirty or clean. Now when they were made aware of the repercussions of the dirty water, they demand clean water as crops yields more, live stock remains healthy and copious amount of milk is being produced. This also had an overall positive effect on the hygiene of the village as they are getting healthy things to eat without any toxic or unhygienic elements in it. Notion of crop rotation is also practiced over there. It was first started in 16Th century and its main purpose was to give the fields some rest in order to gain some nutrition and minerals so it could give better yield in the next harvest. (Jeffery, 2001). . The disadvantages associated with this solution are also there. First of all they are dealing with the kharif crops and no other cash crops are added to the carts. Also, electricity and gas supply is required for sugar mill to start operating and until its availability to the area; the sugar mill unit can not be set up. Moreover, the water supply is not ensured as there is no permanent canal in the area and it can be a big problem if rainfall cycle gets disturbed. (Jeffery, 2001) Tackling the very the first option of bringing the pipe line, the local representatives who have say in both the federal and district government came up with the proposal of bringing in water from a British made dam located 8km from the area through a pipe line in cooperation and collaboration of Sugar Mill. Seeing from the plannerââ¬â¢s point of view, taking water from the neighboring dam will give a respite to locals from importing in costly water tankers from the dam. (Jeffery, 2001) One major positive point behind the whole project is that no hill slopes modifications are required for the construction of pipe line. If we scrutinize the positives of the project more closely we come to a conclusion that water pipe line is always imperative for a locality that is underprivileged due to the insufficient supply of water for most of the year. So in this regard if direct access of water is given to the village, it will not only be used for agricultural purposes but also for the domestic use too. Water is the basic necessity of life so ease of its availability will certainly improve hygiene conditions of the locals. Most of the diseases which pop due to insufficiency of water shall be wiped out due to its supply. Most of all, water will bring in development in the locality as more people will be attracted to the place which would in turn lead to the social development of the area too. (Lewis, 2004). Sugar cane is a cash crop, so cultivating it will for sure help locality to raise its standards from the past. Growing sugar will also exert a pull on Sugar Mill owners to set up their plants near the area so they can procure the crop as soon as it is ready. This would bring in employment for the villagers which would raise their income levels and thus will increase economic activity in the area. Extra revenues will lead to more investments in markets in the village which also include purchase of new land, making of new shops and stores etc. (Wirthman, 2001) If we see the dark side of the picture, one can harbinger that in times to come the plan does not seem to be working efficiently as it is meant to be. First of all, pipe line is not going to generate enough employment for the village which would give the locals a cushion against their financial problems. Moreover when pipe line is completed, villagers will realize that it was a momentary bonus for them as this job was not there on permanent basis. (Wirthman, 2001) Looking at the cultivation of the sugar cane itself, we find out that the farmers from that locality have a weak financial back bone. Sugar cane requires loads of high quality fertilizers and farmers can not afford it so if they use cheap fertilizers, it would produce low and substandard quality crop which would neither be valuable for the cane grower nor to the sugar mill. Also, if we divert our attention to the local government conditions we see that due to vested interests and nepotism, some groups would use their influence in the division of water from the pipe line. Apart form this; maintenance of the pipe line is also a major issue. It is strongly believed that as the pipe line will be there in the hands of the government, it would not be properly maintain which would be drastic in the long term. (Wirthman, 2001) Laying down such a big pipe line is also a daunting task to undertake. Its maintenance is also one of he biggest issues to handle because if its maintenance costs overrun the economic interests of the locality, then it wonââ¬â¢t be considered as a good project to undertake. So option number one closes with its all positives and negatives. One big question which raises its ugly head is the cultivating sugar cane. Soil in this area had already lost valuable nutrients which had decreased its fecundity and with every harvest, it will continue to become less fertile. (Wirthman, 2001) The experts have already advised the locals not to grow cane in this area as the soil is on the brink of degradation. The reason is that sugar cane requires a lot of fertilizers along with these nutrients. After two or three harvests, the soil looses its potency and turn into a low nutrient soil which is not good for growing next crop of sugar cane harvest, even for second crops (grains, pulses). Thus in the long run, this pipe line will be used for the domestic purposes only in stead of watering the field for growing the cash crops like sugar cane. (Wirthman, 2001) Conclusion: In the light of all the positives and negatives discussed earlier, we firmly believe that the practices started by villagers of neighboring Aloke Taluka very much gratify all the questions brought forward in the beginning of the research paper. The consequences of these practices would result in great benefit for the entire village and its inhabitants (Verne, 1999). If we analyze it, we see that in the area, 20% of the houses have a direct access to the fresh water from springs whereas rest of the area have an access to water from other different sources which would uplift the living standards of that locality and will make people self sufficient in financial, economical and social terms which would in term enable them to arrange their own amenities of life not being provided by government up till now. The average capacity of water available to people can be raised up to 750 liters a day and can rise further too. This can only take place if 73000cubic meters of water can be stored in around 14 masonry check damns and gabions (Wirthman, 2001). A winter crop can also be grown as an alternative or second crop. This all will generate economic activity in the area which will open up new markets for the villagers adding up extra revenues in their annual income. Uplifting of standards will increase morale of people. They now have a sense that they need to keep their appearance reasonable and keeping up homes and houses is essential. People will now have surplus resources which will be used in research purposes with different cash crops such as grafting and making new ways of minting money. When people will become self sufficient at the lower levels, they would be able to afford school for their children which in the long run will be beneficial for the whole society. Many of the well- off farmers has bought some machinery for their farms in order to mechanize threshing and plowing of their crops and fields. (Prasad, 2002).

Whale Species That Migrate and the Distance Traveled
Whales may migrate thousands of miles between breeding and feeding grounds. In this article, you can learn about how whales migrate and the longest distance a whale has migrated. About Migration Migration is the seasonal movement of animals from one place to another. Many species of whales migrate from feeding grounds to breeding grounds - some traveling long distances that may amount to thousands of miles. Some whales migrate latitudinally (north-south), some move between onshore and offshore areas, and some do both. Where Whales Migrate There are over 80 species of whales, and each has their own movement patterns, many of which are not yet fully understood. In general, whales migrate toward the colder poles in the summer and toward the more tropical waters of the equator in the winter. This pattern allows whales to take advantage of the productive feeding grounds in colder waters in the summer, and then when productivity lowers, to migrate to warmer waters and give birth to calves.à Do All Whales Migrate? All whales in a population may not migrate. For example, juvenile humpback whales may not travel as far as adults, since they are not mature enough to reproduce. They often stay in cooler waters and exploit the prey that occurs there during the winter. Some whale species with fairly well-known migration patterns include: Gray whales, which migrate between Alaska and Russia and Baja CaliforniaNorth Atlantic right whales, which appear to move between cold waters off the Northeastern US and Canada to waters off South Carolina, Georgia and Florida.Humpback whales, which move between northern feeding grounds and southern breeding grounds.à Blue whales. In the Pacific, blue whales migrate from California to Mexico and Costa Rica. What Is the Longest Whale Migration? Gray whales are thought to have the longest migrations of any marine mammal, traveling 10,000-12,000 miles round trip between their breeding grounds off Baja California to their feeding grounds in the Bering and Chukchi Seas off Alaska and Russia. A gray whale reported in 2015 broke all marine mammal migration records - she traveled from Russia to Mexico and back again. this was a distance ofà 13,988 miles in 172 days. Humpback whales also migrate far - one humpback was sighted off the Antarctic Peninsula in April 1986 and then resighted off Colombia in August 1986, which means it traveled over 5,100 miles. Whales are a wide-ranging species, and not all migrate as close to shore as gray whales and humpbacks. So the migration routes and distances of many whale species (the fin whale, for example) are still relatively unknown. Sources Clapham, Phil. 1999. ASK Archive: Whale Migrations (Online).

About Isotopic Dating Yardsticks for Geologic Time
The work of geologists is to tell the true story of Earths historyââ¬âmore precisely, a story of Earths history that is ever truer. A hundred years ago, we had little idea of the storys lengthââ¬âwe had no good yardstick for time. Today, with the help of isotopic dating methods, we can determine the ages of rocks nearly as well as we map the rocks themselves. For that, we can thank radioactivity, discovered at the turn of the last century. The Need for a Geologic Clock A hundred years ago, our ideas about the ages of rocks and the age of the Earth were vague. But obviously, rocks are very old things. Judging from the number of rocks there are, plus the imperceptible rates of the processes forming themââ¬âerosion, burial, fossilization, upliftââ¬âthe geologic record must represent untold millions of years of time. It is that insight, first expressed in 1785, that made James Hutton the father of geology. So we knew about deep time, but exploring it was frustrating. For more than a hundred years the best method of arranging its history was the use of fossils or biostratigraphy. That only worked for sedimentary rocks and only some of those. Rocks of Precambrian age had only the rarest wisps of fossils. No one knew even how much of Earth history was unknown! We needed a more precise tool, some sort of clock, to begin to measure it. The Rise of Isotopic Dating In 1896, Henri Becquerels accidental discovery of radioactivity showed what might be possible. We learned that some elements undergo radioactive decay, spontaneously changing to another type of atom while giving off a burst of energy and particles. This process happens at a uniform rate, as steady as a clock, unaffected by ordinary temperatures or ordinary chemistry. The principle of using radioactive decay as a dating method is simple. Consider this analogy: a barbecue grill full of burning charcoal. The charcoal burns at a known rate, and if you measure how much charcoal is left and how much ash has formed, you can tell how long ago the grill was lit. The geologic equivalent of lighting the grill is the time at which a mineral grain solidified, whether that is long ago in an ancient granite or just today in a fresh lava flow. The solid mineral grain traps the radioactive atoms and their decay products, helping to ensure accurate results. Soon after radioactivity was discovered, experimenters published some trial dates of rocks. Realizing that the decay of uranium produces helium, Ernest Rutherford in 1905 determined an age for a piece of uranium ore by measuring the amount of helium trapped in it. Bertram Boltwood in 1907 used lead, the end-product of uranium decay, as a method to assess the age of the mineral uraninite in some ancient rocks. The results were spectacular but premature. The rocks appeared to be astonishingly old, ranging in age from 400 million to more than 2 billion years. But at the time, no one knew about isotopes. Once isotopes were explicated, during the 1910s, it became clear that radiometric dating methods were not ready for prime time.à With the discovery of isotopes, the dating problem went back to square one. For instance, the uranium-to-lead decay cascade is really twoââ¬âuranium-235 decays to lead-207 and uranium-238 decays to lead-206, but the second process is nearly seven times slower. (That makes uranium-lead dating especially useful.) Some 200 other isotopes were discovered in the next decades; those that are radioactive then had their decay rates determined in painstaking lab experiments. By the 1940s, this fundamental knowledge and advances in instruments made it possible to start determining dates that mean something to geologists. But techniques are still advancing today because, with every step forward, a host of new scientific questions can be asked and answered. Methods of Isotopic Dating There are two main methods of isotopic dating. One detects and counts radioactive atoms through their radiation. The pioneers of radiocarbon dating used this method because carbon-14, the radioactive isotope of carbon, is very active, decaying with a half-life of just 5730 years. The first radiocarbon laboratories were built underground, using antique materials from before the 1940s era of radioactive contamination, with the aim of keeping background radiation low. Even so, it can take weeks of patient counting to get accurate results, especially in old samples in which very few radiocarbon atoms remain. This method is still in use for scarce, highly radioactive isotopes like carbon-14 and tritium (hydrogen-3). Most decay processes of geologic interest are too slow for decay-counting methods. The other method relies on actually counting the atoms of each isotope, not waiting for some of them to decay. This method is harder but more promising. It involves preparing samples and running them through a mass spectrometer, which sifts them atom by atom according to weight as neatly as one of those coin-sorting machines. For an example, consider the potassium-argon dating method. Atoms of potassium come in three isotopes. Potassium-39 and potassium-41 are stable, but potassium-40 undergoes a form of decay that turns it to argon-40 with a half-life of 1,277 million years. Thus the older a sample gets, the smaller the percentage of potassium-40, and conversely the greater the percentage of argon-40 relative to argon-36 and argon-38. Counting a few million atoms (easy with just micrograms of rock) yields dates that are quite good. Isotopic dating has underlain the whole century of progress we have made on Earths true history. And what happened in those billions of years? Thats enough time to fit all the geologic events we ever heard of, with billions left over. But with these dating tools, weve been busy mapping deep time, and the story is getting more accurate every year.

Guernica By Pablo Picasso And Executions Of Art - 879 Words
When comparing the two art pieces of art, ââ¬Å"Guernicaâ⬠by Pablo Picasso and ââ¬Å"Executions of the Third of Mayâ⬠by Goya, you may interpret the underlying meaning to be the same. However, the era in which these paintings were created are noticeably different as well as the techniques. The history in which these two works were created is intriguing. The implicit and explicit similarities and differences between these two historical pieces are astonishing. ââ¬Å"Guernicaâ⬠, which was created in 1937 was Picassoââ¬â¢s reaction to the bombing of a Spanish city that the name of the work derived its name from. During the Spanish Civil War, Germany had supported the Nationalists side and provided them with weapons and other supplies, so when Adolf Hitlerâ⬠¦show more contentâ⬠¦A mother cries in agony while holding a small child in her arms, most likely one of the many victims who lost their lives. On the far right side of the painting, you can see a woman o n her knees, examining the skies as if she is expecting another bomb to fall from the sky. It is evident that her right leg is already injured. Violence and anguish is displayed in this famous piece of art. Francisco Goya was a Spanish Romanticist painter who was born 1746 and died in 1828. Although he was born near Saragossa, he was living in Madrid when he painted ââ¬Å"Executions of the Third of Mayâ⬠. The famous painting refers to 1807 when Napoleon Bonaparte wanted to make an alliance with King Charles IV in order to conquer Portugal, but his true plan was to take over Madrid. When the French troops stormed Madrid, Napoleon claimed that they were just passing through, but when they began taking over, king Charles IV soon realized the alliance was a hoax. Soon after Napoleonââ¬â¢s brother, Joseph Bonaparte became the new king of Spain. The siege lasted three days and on the second day a rebellion broke out and on the third day, the rebels were slaughtered. It is said that Goya himself witnessed the murders from atop the hill of Principe Pio and once the massacre had ended he began making sketches of the bodies under his lantern. Although the story is not proven, it is clear that it affected him greatly.

The romantic period focused on the creativity of an individualââ¬â¢s art. However, after reading the two lectures, I believe the modernism period is when artists really started to discover innovative ways to create art. There were many artists in each genre of painting, composing, and poetry who had strong influences during the modernists period. The one artist who stuck out the most to me was Pablo Picasso. Pablo Picasso is one of the most well known artists of the modernism period.

Play in school Essay Example For Students
Play in school Essay There were different doors on the stage, the ones on stage left were poor and battered leading into council houses; this is where the Johnston family lived, the doors on stage right was hidden but the ones shown were new posh doors maybe leading into mansions. To show the Lyons house they used flying scenery; one wall flat of a house to show a living/dinning room. This also happened when the scene was in Mrs Johnstons kitchen. To show Mickey and Lindas house they rolled on another wall flat of a living room. The doors stayed on the stage for all of the play, the only time they changed is when the Johnston family moved to the countryside; they were still council but were in much better condition. A sort of raised platform this was used by the always-watching narrator who never left the stage, to watch, to enter and exit to a wing upstairs, it led to were the orchestra were.Ã Only a few scenes changed throughout the play but most of the time to change the scene the stage were just striked. The biggest scene change was when the scene changed from the street houses to the countryside, the backdrop changed here also from the houses and factories of the city to the farms and fields of the countryside. This took place during the interval. Sound and music were also used to display the emotions in each scene. The type of sound was mainly special effects for things like thunder when Mrs Lyons went insane and birds tweeting in the country scene.Ã The orchestra also contributed to the sound before and during the play, it was nothing too evident, which did not really give much of an impact, which is a good thing.Ã The Music during the play was very harsh and the pace was always fast, the songs were very hum able and catchy but I believed that the played Marilyn Monroe and shoes upon the table a bit too much as they started to get a bit annoying after a while During the play, the stage was lit using foot lights and floodlights, which made it quite bright. The only times when the scene was not light was either when the effect of night was wanted or when Mrs. Lyon was going insane and flashing lights with blue gels were used, also a tree or flame was shown on the stage using a shadow.Ã There was a few times in which light effects were used, for example when there were blackouts to show the years gone past, flashing lights were also used to show different shops and arcades in the carnival when Linda, Mickey and Eddie were growing up. This was effective, and was an amazing contrast compared to the scene with Mrs Lyons, which had a completely different mood that was well conveyed by the lighting used in both scenes. The play would not have been as good if only the house lights were used. The costumes in the play reflected the character and his or her personality well. When they were children Mickey wears torn shorts and T-shirt that do not fit him properly, Eddie wears shorts, a shirt and a jumper and white knee high socks that were always clean and tidy. As they get older they stop wearing shorts and start to wear jeans and jumpers when finally they grow up to show their maturity they wear jeans, shirts and blazers. Not only do the costumes show the age changes but also the difference in class; Eddie would wear designer, posh clean clothes all the way through the play while Eddie would wear standard middle class clothes .u27677b13a3256320d10e6604778ffc8f , .u27677b13a3256320d10e6604778ffc8f .postImageUrl , .u27677b13a3256320d10e6604778ffc8f .centered-text-area { min-height: 80px; position: relative; } .u27677b13a3256320d10e6604778ffc8f , .u27677b13a3256320d10e6604778ffc8f:hover , .u27677b13a3256320d10e6604778ffc8f:visited , .u27677b13a3256320d10e6604778ffc8f:active { border:0!important; } .u27677b13a3256320d10e6604778ffc8f .clearfix:after { content: ""; display: table; clear: both; } .u27677b13a3256320d10e6604778ffc8f { 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; } .u27677b13a3256320d10e6604778ffc8f:active , .u27677b13a3256320d10e6604778ffc8f:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u27677b13a3256320d10e6604778ffc8f .centered-text-area { width: 100%; position: relative ; } .u27677b13a3256320d10e6604778ffc8f .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u27677b13a3256320d10e6604778ffc8f .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u27677b13a3256320d10e6604778ffc8f .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; } .u27677b13a3256320d10e6604778ffc8f:hover .ctaButton { background-color: #34495E!important; } .u27677b13a3256320d10e6604778ffc8f .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u27677b13a3256320d10e6604778ffc8f .u27677b13a3256320d10e6604778ffc8f-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u27677b13a3256320d10e6604778ffc8f:after { content: ""; display: block; clear: both; } READ: Physical Therapy EssayIt was the first time that I saw Blood Brothers and I understood the play to a certain extent but not as fully as the other people did because I am not studying the play in school.Ã Although the production is a brilliant one, I thought that the actors playing the characters of Mrs. Lyons and Mrs Johnston was not thought out enough and turned out to be characterless and bland. An example of this is when Mrs Lyons appears in Mrs Johnstons home and threatens her, the struggle between the two ended up to be a bit pathetic. The characters of Mickey and Linda were a lot better, they were exciting and competent, they also were able to show their characters development well through out the play. My favourite character in the play was Mickey. Mickeys character was the one that in my opinion was more developed, the one that stood out from the other main characters and the best acted. I also liked the way that his character gradually changed through out the play and not many actors can carry it out as well as he did. The change of Mickeys character was obvious during the play but the actors change was not. Apart from Mrs Lyon and Mrs Johnston, I believe the choice of cast was very well done. It is my favourite play, so far because it is filled with humour, Romance, attraction and physical humour.Ã As a whole, I thought the audience really enjoyed the performance and I liked the way the director slipped in a few jokes.Ã Along with the tears, this compelling and heart-wrenching story of the Liverpool working class mum, pressured into giving away one of her newborn twins at birth so that he can have a better life, also has warmth, tenderness, love and laughter
