Bury My Heart At Wounded Knee :: essays research papers

Bury My Heart at Wounded Knee   Ã‚  Ã‚  Ã‚  Ã‚  The Indians were being confined to crowed reservations that were poorly run, had scarce game, alcohol was plentiful, the soil was poor, and the ancient religious practices were prohibited. The Indians were not happy that they had been kicked off there land and were now forced to live on a reservation. The Indians then began to Ghost Dance a form of religion it is said that if the Indians were to do this trance like dance the country would be cleansed of white intruders. Also dead ancestors and slaughtered buffalo would return and the old ways would be reborn in a fruitful land. Once the Bureau of Indian affairs noticed what was going on they began to fear this new religion would lead to warfare. The white peoplewere scared that this new dance was a war dance. They called for army protection. Army was called in to try to curbed this new religion before it could start a war.   Ã‚  Ã‚  Ã‚  Ã‚   The Sioux band tougher led by Little Big Foot. They were heading to Pine RidgeReservation in South Dakota, when the army stopped them and held them at gun pointovernight. Big Foot’s group contained about 300 people two-thirds of them were women and children. While the soldiers numbered around 500 and were armed with automatic weapons. The next morning when the army began to disarm the Indians a shot rang out then the gun fire began leaving about 200 Indians dead in the snow. Thirty soldiers were also killed in the massacre. The soldiers that lost there lives were most likely killed by their own men in friendly fire. Wounded Knee is said to have been the last battle of the war but it was not so much a battle as it was a massacre. It was in fact the last exchange of fire between the army and the Sioux.

Suburbia: Inappropriate Growing Environment :: Suburbs Education Learning Essays

Suburbia: Inappropriate Growing Environment There's a reason people go to school in their youth rather than after they get older. It's because the childhood years are the ones during which the potential for learning is the greatest. Youths' impressionable minds have far less trouble picking up important concepts like mathematics and grammar than do adults'--in fact, young minds seem oftentimes to learn automatically or accidentally. It stands to reason, therefore, that adults should take advantage of that impressionability to educate the leaders of the future in areas such as art, basic economy, and interpersonal behavior while their chances of learning are still so great. In a world and a time where the quest to become a functional and productive member of society is such a difficult one and so rarely completed, one can't help feeling that it's absolutely imperative that those in charge of raising the next generation ensure that they do so under the best possible circumstances: that is, in a living environment conducive to intellectual and emotional challenge and growth. However, such is clearly not always the case. As a place to develop and mature, one of the worst locales in America--and possibly the most misjudged--is suburbia. A vast wasteland of dressed-up emptiness, the typical suburban town promises an idyll it could never truly hope to deliver. An attempt at compromise between the country and the city, it instead combines the worst aspects of both. And as we shall see, children who grow up in this abyss will find their social lives constantly lacking and their cultural needs rarely met. The causes of these shortcomings of the suburban town are firmly rooted in its geographical and political structure, as well as in the attitudes of many suburban adults. Geography "The suburbs represent the triumph of accessibility over proximity," writes Harlan Paul Douglass in his 1920s book The Suburban Trend (187). Douglass is writing to defend his home--in his own words, an "apologia for suburban life"--but he appears sadly unaware of the sinister truth to his statement (v). Indeed, some semblance of indiscriminate accessibility is a reality in the suburbs--for people of means. That is to say, people who can drive, or who live near public transportation routes. Children tend not to fall into either of these categories. On the one hand, most are too young to get driver’s licenses or too poor to pay for a car and auto insurance. On the other, even those who live within walking distance of mass transit systems may find its cost prohibitive, or else their parents may forbid them to use it for fear of what kind of people they'll meet.

The Unsuspecting Hero of J. R. R. Tolkiens The Hobbit Essay -- Tolkie

The Unsuspecting Hero of The Hobbit Our tendency to romanticize it notwithstanding, childhood is tough. It is not, primarily, the time of nonstop games and fun that we would all like to remember. Childhood is marked by fun and games, to be sure, but it is also marked by a feeling of powerlessness in the face of larger and older adults. These adults are in full control of nearly every aspect of children's lives. From when they go to bed to what they eat, children are allowed to make very few choices of any significance. Because they are smaller, younger, weaker, and less trusted to be able to make wise decisions than are adults, children can easily feel powerless or even unimportant in comparison with these adults. The Hobbit, J. R. R. Tolkien's classic of children's literature, features a protagonist who has to deal with the sense of powerlessness and inferiority that children can easily feel. Bilbo Baggins, the novel's diminutive hero, is dramatically smaller and several years younger than the thirteen dwarves whose adventure he shares. Indeed, the dwarves initially see him as a sort of a child who cannot possibly help them in their quest for treasure. Bilbo proves himself to be a true hero throughout the course of the novel, however, saving the dwarves' lives more than once and providing the secret to killing the dragon Smaug. Tolkien obviously meant for children to identify with Bilbo Baggins, and his heroics were clearly intended to bring pleasure on a far more personal level than the exploits of a superhuman hero such as Sir Lancelot. Indeed, it can be argued that by choosing to make Bilbo the smallest and youngest member of the party, Tolkien allows his child readers the pleasure of iden tifying directly with his her... ...t children are far more inspired by the triumphs of other children than they are by the triumphs of adults or even adolescents, and so he wrote about a character who does vindicate himself and mature, but who remains, for all of that, a child. Children who read this novel will still undoubtedly be treated as though they are incapable of fending for themselves, and they will still undoubtedly be terrified of things around them, but they will feel a sense of vindication whenever they think of Bilbo Baggins. After all, Bilbo proves that one can be brave, wise, and heroic despite the fact that one is a "mere" child. Works Cited Carter, Lin. Tolkien: A Look Behind "The Lord of the Rings."

Genres Of Literature

Genres of literature are important to learn about. The two main categories separating the different genres of literature are fiction and nonfiction. There are several genres of literature that fall under the nonfiction category. Nonfiction sits in direct opposition to fiction. Examples from both the fiction and nonfiction genres of literature are explained in detail below. This detailed genres of literature list is a great resource to share with any scholars. Types of Nonfiction: Narrative Nonfiction is information based on fact that is presented in a format whichtells a story. Essays are a short literary composition that reflects the author’s outlook or point. A short literary composition on a particular theme or subject, usually in prose and generally analytic, speculative, or interpretative. A Biography is a written account of another person’s life. An Autobiography gives the history of a person’s life, written or told by that person. Often written in Narrativ e form of their person’s life. Speech is the faculty or power of speaking; oral communication; ability to express one’s thoughts and emotions by speech, sounds, and gesture.Generally delivered in the form of an address or discourse. Finally there is the general genre of Nonfiction. This is Informational text dealing with an actual, real-life subject. This genre of literature offers opinions or conjectures on facts and reality. This includes biographies, history, essays, speech, and narrative nonfiction. Nonfiction opposes fiction and is distinguished from those fiction genres of literature like poetry and drama which is the next section we will discuss.

On Some Motifs in Baudelaire

Seminar Questions 1. Modernism- Benjamin, Walter â€Å"On some Motifs in Baudelaire† Question 1: In â€Å"On some Motifs in Baudelaire† Walter Benjamin argues that extended exposure to stimuli, or shocks, in the environment alters the human experience of our world and creates a conditioned reaction within the crowd. How does this overstimulation shape our current society and was Benjamin correct in warning against it? Walter Benjamin implied that our minds are not equipped with the facilities to handle these shocks.These develop into environmental stressors and thus our decision-making skills are weakened and we just follow the person in front of us. While over stimulation is an epidemic in current times I do not believe it has created mindless hordes of people. The biggest effect of over stimulation is an individual’s continuous partial attention. Not being able to focus on one thing means focusing on multiple tasks and then not doing any of them completely. Our minds rapidly switch between a variety of separate channels.Initially, this may lead to fatigue. However, the mind can build off of this and become stronger. This is why current culture deems louder, brighter, faster, and shocking media as â€Å"better†. For society to notice anything it needs to be an attention grabber, and when society is constantly focusing on a variety of media you are bombarded with I do not agree that these shocks create a conditioned reaction within the crowd but I do believe they create them within the individual.An individual’s need to process multiple channels of information at once allows information that isn’t sold as the biggest, brightest, and best to fall through the cracks. ? Question 2: Walter Benjamin’s description of a flaneur as a â€Å"detached observer† describes a spectator who seems to maintain their individuality from the crowd. One that can break free from rationalized understandings while being opened up to new perspectives and experiences. Do modern cities and their architecture embrace the idea of the flaneur? Modern architecture embraces the alienating nature of modernity.It creates cities that encourage crowds and a fast-paced way of life. Commercial typologies like malls, subway systems, and high-rise office buildings create a certain environment that do not encourage individual reactions. When something is designed to garner a similar reaction from different types of people it lessens the chance for chaos and also allows a behavioural expectation to be set within a certain environment. When people are expected to react in similar ways it allows the people in charge to be better prepared for distinctive instances.Police can work better, government can create more effect universal policies and transportation can run smoother. Therefore, it benefits the rulers of a city to for modern architecture to follow the same instances. Perhaps the flaneur is the architect, but the vision and idiosyncrasies that the architect tries to instill within each project get syphoned out through different real world factors. Factors that include: budgets, client’s tastes, feasibility, and materiality. These factors chip away at truly city changing architecture and create an environment where the same projects continue to get churned out.

What is Mangrove? The term ‘mangrove', is used to refer to the highly adapted plants found in tropical forest communities or the ecosystem itself. The term ‘mangrove' may have been derived from a combination of the Malay word ‘manggi-manggi', for a type of mangrove tree (Avicennia) and the Arabic à ¢â‚¬Ëœel gurm', for the same, as ‘mang-gurm'. Mangrove is a tree or shrub that grows in muddy, chiefly tropical coastal swamps. Generally exceeding one half metre in height. Mangrove plants vary genetically and those found on land are not of same types.They are of different types. An increase in mangroves has been suggested for climate change mitigation. Big groups of mangroves and other plants are called mangrove swamps, mangrove forests, and sometimes simply manga. The mangrove community is the biotic part of our ecosystem. Importance And Role Of Mangrove Ecosystems: Mangroves are not only important but crucial for the coastal areas. The most important role of mangroves is that they protect vulnerable coastlines from waves because they hold the soil together and prevent coastal erosion.Mangroves shield inland areas during storms and minimize damage. Example: For example, learning from the 2005 tsunami in Asia, there were no deaths in the areas which had mangrove forests, com pared to those areas without, which suffered massive causalities. Mangrove forests provide homes for several species of plants and animals. Migratory shorebirds and waders seek the mudflats for food. Birds establish large roosting and nesting sites in mangroves. Several species of fish, monkeys, and turtles find refuge there.The beaches along more mature undisturbed mangroves also serve as nesting sites for endangered sea turtles. Mangroves are fish nurseries as they serve as a source of food for fish and crabs that live in rivers and the shallow areas of the sea/ocean. And they provide a safe haven for juvenile fish, and crab located on coastline. Mangroves therefore contribute significantly in fishing industry and provide us with our fish resource. ACT AS A FILTERING SYSTEM They act as filtering systems for the run-off and ground waters, clarify adjacent open water, which facilitates photosynthesis in marine plants.Mangroves also help to control other forms of pollution, including excess amounts of nitrogen and phosphorous, petroleum products, and halogenated compounds. Mangroves stop these contaminants from polluting the ocean waters through a process called rhizofiltration. TRAP DEBRIS AND SILT Mangroves trap debris and silt contributing to soil formation and stabilizing the coastline. SERVE AS HABITAT Their roots provide shelter for many marine and terrestrial animals, protecting them from ocean currents and strong winds. Many threatened or endangered species reside inside.PRODUCE NUTRIENTS Mangroves shed a large amount of leaf litter, being dropped and then broken down by bacteria and fungi which is made available to the food chain of aquatic animals. Therefore mangroves contribute to productivity in off shore water. SERVE AS NURSERY AND REFUGE For many juvenile fish and invertebrates such as spiny lobster, gray snapper, jacks and barracuda. Mangroves are the nesting grounds for many water birds. Disappearance Of Mangroves: Mangrove forests are one of th e world’s most threatened tropical ecosystems. More than 35% of the world’s mangroves are already gone.The figure is as high as 50% in countries such as India, the Philippines, and Vietnam, while in the Americas they are being cleared at a rate faster than tropical rainforests. 12 species of mangroves found in India are considered to be ‘Critically Endangered’ and a total of 57 mangrove and mangrove-associated species are considered threatened. The main reasons for the destruction in the area are mainly due to population pressure in and around the mangrove belts. Causes Of Disappearance Of Mangroves: * Mangroves are extremely sensitive to current rising sea levels caused by global warming and climate, Cyclones, typhoons and strong wave action. Insect such as Wood borers, Caterpillars, beetles eat the mangrove foliage and damage the wood. * Weeds often occupy deforested mangrove areas and restrict the re-growth of mangrove tree species. * Barnacles are a ty pe of arthropod which when attached to young seedlings, interferes with respiration and photosynthesis and delays seedling growth. Oysters, Crabs, Gastropods also damage the plant parts. * Mangrove trees are used for firewood, construction wood, pulp production, charcoal production, and animal fodder.While harvesting has taken place for centuries, in some parts of the world it is no longer sustainable, threatening the future of the forests. * Dams and irrigation reduces the amount of water reaching mangrove forests changing the salinity level of water in the forest. When salinity becomes too high the mangroves cannot survive. Freshwater diversions can also lead to mangroves drying out. * Pollution is the major problem in world. Toxic man-made chemicals carried by river systems from sources upstream can kill animals living in mangrove forests, while oil pollution can smother mangrove roots and suffocate the trees.Effects Of Mangroves Disappearance: Mangroves are saline coastal forest s include heavy biomasses of trees and shrubs. Such forests are essential in protecting the coastal regions they surround from erosion, but they have also been shown to help mitigate the effects of tropical storms by buffering coastal communities against hurricane-like winds and tidal surges. * Widespread destruction of mangroves (Bahamas, Australia) has resulted in the loss of some of the world’s most diverse ecosystems. As a side effect his has greatly increased shoreline hazards and beach erosion rates. The greatest benefit of mangroves is their ability to reduce storm surge. This benefit is long-term and requires no maintenance. The 1999 super typhoon, Orissa, killed over 10,000 people in India drowning many with its powerful storm surge * The widespread destruction of Burma’s mangroves has magnified another human disaster in the wake of cyclone Nargis, a tragedy that might have claimed more than 100,000 lives, according to a news services’ estimates.Present Condition Of Mangroves In Pakistan Over 600,000 hectares of Pakistan’s coastline is under mangrove forestation. The coastal communities as well as the fisheries of the coast depend upon this ecosystem their existence is associated with its well-being. Mangroves historically have been considered to be wastelands. The vital flow of the Indus River into the Indus Delta, which constitutes one of the most extensive mangrove areas along the Pakistani coast, is heavily polluted by a variety of ndustrial effluents, sewage, solid waste and nutrient-enriched irrigation water. THE Indus delta mangroves are under the control of the Sindh forest department (280,470 ha), Port Qasim Authority (64,400 ha) and Sindh Board of Revenue (255,130 ha). The area under control of the forest department and Port Qasim is declared as `protected forest` and the area under the control of the Board of Revenue is classified as `government wasteland`. The Indus delta provides subsistence to approximately 20 0,000 people throughout the year.A recent study by WWF – Pakistan (2006) has estimated the existing cover of the Indus delta mangroves around 73,000 ha. Historically, there used to exist eight species of mangroves which have declined to four species at present.

The beet (Beta vulgar's) is a plant in the Chenopodiaceae family. It is best known in its numerous cultivated varieties, the most well known of which is probably the red or urple root vegetable known as the beetroot or garden beet.However, other cultivated varieties include the leaf vegetables chardand spinach beet, as well as the root vegetables sugar beet, which is important in the production of table sugar, and mangelwurzel, which is a fodder crop. Three subspecies are typically recognised. All cultivated varieties fall into the subspecies Beta vulgaris subsp. vulgar's, while Beta vulgaris subsp. maritima, commonly known as the sea beet, is the wild ancestor of hese and is found throughout the Mediterranean, the Atlantic coast of Europe, the Near East, andlndia.A second wild subspecies, Beta vulgaris subsp. adanensis, occurs from Greece to Syria. Beetroot cells like any other eukaryotic cells have many types of cell organelle present. Some of these organelles are bounded by a sing le membrane, e. g. lysosomes, Golgi apparatus, vacuoles; some are bounded by two membranes (an envelope), e. g. nucleus, mitochondrion. Beetroot appears as a dark red/ purple colour and this is caused by the betalain pigment, which is contained ithin the vacuole of beetroot cells.In order for the betalain to leave the cell it needs to pass through 2 different membranes; the membrane bounding the vacuole and the membrane enclosing the cell. Betalain pigments, named after the Red beet (Beta vulgaris). They replace anthocyanins in plants of the order Caryophyllales (Cacti, beets & Co. , bougainvillaea, phytolacca, large-flowered purslane etc and also in some fungi such as fly agaric). Two categories of betalains exist and each have distinct color and chemical properties.Betacyanins convey a blue-violent to reddish-purple coloring, are a source of antioxidants and are susceptible to color changes depending antioxidants and are relatively stable. Betalains are found exclusively within on e plant order, which includes beets, prickly pear cactus, chard and amaranth. Betanin is a specific betacyanin and the most prominent pigment in the red beet root where it contributes between 75% – 90% of the total visible color. Plasma membrane Plasma membrane is a biological membrane that separates the interior of all cells rom the outside environment.The cell membrane is selectively-permeable to ions and organic molecules and controls the movement of substances in and out of cells. It consists of the phospholipid bilayer with embedded proteins, which are involved in a variety of cellular processes such as cell adhesion, ion conductivity and cell signaling. The plasma membrane also serves as the attachment surface for the extracellular glycocalyx and cell wall and intracellular cytoskeleton. Plasma membrane proteins function in several different ways.
