Essay --

While raining, your child walks six blocks to the bus stop with no shelter. When the bus finally arrives, it is in need of thirty minutes to get to school. Eventhough, there is a school a couple blocks down from their house, it is not even a thought in the eyes of the law due to the mere color of their skin. This is not just the story of Oliver Brown and his family, but many other families experiencing discrimination throughout the world. Brown was ready for a change, so he and the NAACP gathered evidence to take on the courts. Through the process of many getting denied the acceptance of their children in school, the National Association for the Advancement of Colored People gathered evidence for a lawsuit against the courts. Oliver Brown and many others were tired of the saying seperate but equal and the inferiority they were given through out their lives. Instead of just accepting the opinions of others and sitting around wanting a change, they stood for what they believed in, beco ming the turning point in America. Judith Conaway was the author of the book Brown vs. Board of Education. In this book, Conaway describes in detail, the discrimination and experiences our ancestors had to go through. Through the triumphs they experienced, laws changed where segregation was abolished and everyone is equal. She says that the "supreme court had ruled that racial segregation in public schools denied African Americans equal protection under the law." She also said that the courts agreed that seperate schools harmed black children both academically and psychologically. For example, African American children would choose white dolls over black dolls because the black dolls were considered ugly with their heads down. This decision of the c... ...aiting for. We are the change that we seek. All in all, just like Oliver Brown and the NAACP , do not live life waiting for things to happen, take control of today and be the future of yet to come. If you live life in fear and accept what is handed to you, you can never succeed. The decision of Brown vs. Board of Education did not just effect our ancestors, if effected us today and future generations. It accomplished more than the abolishment of segregation in school, it abolished segregation laws throughout the world. I am able to go to school everyday knowing I am not being discriminated against because the color of my skin. Not only that, I am able to go to a restaurant, movie theater, and even a water fountain without a sign saying white or black people only. In my oppinion they constituted the future for my education, all those before me, and those to follow.

English: Literacy and Century Learners Essay

English is a widely-used language that is originally used by the countries United States, Great Britain, England and many more. English is the universal language because it is widely used by many people like Asians, Europeans, Africans and many more. However, how can we use English in shaping 21st century learners? English has many purposes that can help shape 21st century learners. One is we can use English in expressing our thoughts, ideas, feelings and many more. Because English is important, we need to use English precisely because if we don’t use our language properly it will result to different interpretations that will lead to chaos. Moreover, we need to master our skills in English in order for us to express what we know because in the future I believe that most of our professions need English as a medium for communicating. Another reason why we need to master English is today, many people are engaged into new technologies that requires new and different skills and that involves our literacy. Literacy demands nowadays, have changed along with the changes that happen in our world. Literacy is very important to a person because a literate person possesses a wide range of abilities and competencies compared to a person who is illiterate. Another reason why we need to master English is if we are communicating to a foreigner we use English as our medium of instruction in order for us not to misinterpret each other. Another purpose of English is to bring a new world. We can attain the world we wanted by using English in uniting all the people in the world because all of us wanted the same thing which is a new world. Another purpose is we can empower the voice of the youth with the use of English because I believe in the saying of Dr. Jose Rizal â€Å"ang kabataan ay ang pag-asa ng bayan†. Furthermore, we need to empower the voice of the youth because if we don’t empower them there will be no hope for our world and no great change will happen in this world we live in right now. English is the key to success. English can make us successful by making a great change through English because I believe language has a great influence and that influence is based on our decision if we want to make our world a better or a worse place. Another is we can be also successful in our lives through English because we use English as a medium of instruction at school and when we become successful in school there is a great chance that in the real life we become successful too. Another is if English did not existed we will not discover the technology we have now that helps in shaping up 21st century learners. Another is if English did not existed there would be no fun at all because there would be no tongue twister, poem, stories and many more. English plays an integral role in our daily lives so let’s give it up to the fullest.

Edna In The Awakening Novel - Free Essay Example

Sample details Pages: 3 Words: 896 Downloads: 5 Date added: 2019/07/31 Category Literature Essay Level High school Tags: The Awakening Essay Did you like this example? In Kate Chopins novel, The Awakening, Edna, a strong, female character lead, ventures out of her comfort zone while breaking through the role appointed to her by society. Throughout the novel, Edna is seen discovering her own identity independent from her husband and children.   Edna is seen always harboring unrealistic dreams that cannot be satisfied, thus characterizing her as a rebellious and selfish adult. Ednas life is symbolized through a series of parrots, mockingbirds, and seagulls that all form personal and metaphorical connections of freedom between Ednas world and her eventual awakening in reality, resembling her literal imprisonment within this society.. Don’t waste time! Our writers will create an original "Edna In The Awakening Novel" essay for you Create order   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Throughout the novel, countless references are made specifically involving parrots. One of which being Madame Lebruns caged parrot that shrieks Allez vous-en! Sapristi (Chopin, 26) at Mr. Pontellier. Thus resembling Ednas need to escape her middle-class life for freedom and space. Parrots are trained to only mimic what theyve heard symbolizing Ednas struggles to express herself because no one else does openly in this time period. This symbolizes Ednas literal imprisonment in this society. In, Edna and the Woman Question, Jules Chametzky states the struggle is for the woman to free herself from being an object or possession defined in her functions, or owned, by others (Chametzky, 236) despite her middle-class advantages. Furthermore, Ednas relation to parrots expands by their ability to silent themselves before being consigned to the regions of darkness (Chopin, 26). Only when a parrots cage is covered, does the parrot stay silent. This signifies Edna whe n she is with her family or husband. Otherwise, with the cage uncovered, a parrot has the right to speak. Such as to when Edna is alone, do her thoughts overcome her and she rebels. Therefore, Edna is characterized as the parrot herself, while Mademoiselle Reisz is specifically characterized as a mockingbird. This is because Mademoiselle Reisz is Ednas only friend who seems to understand her struggle in social and religious conventions. More specifically, Mademoiselle is seen playing the piano with songs that are not her own, such as a mockingbird who mimics sounds they hear. More precisely, the mocking-bird that hung on the other side of the door, whistling his flute notes out upon the breeze with maddening persistence (Chopin, 26) resembles Mademoiselle Reisz, herself. Instantly, in the beginning of the novel, both the parrot and mockingbird are seen being characterized as the same, trapped. However, the mockingbird also relates to Edna in several ways. Along with the parrot, the mockingbird is seen several times being shut-out, symbolizing, once again, Ednas imprisonment in society. Edna finally begins to realize that there is more to the world then a perfect marriage or family. Furthermore, Edna begins making connections between herself and the birds. For example, Edna is characterized as the literal parrot herself, while the other women in this society are the mockingbird because Edna had the courage to speak the language that no one else could. Edna would attempt to be understood, but the other women would just answer back with any coherent reply, although they understood exactly what she was speaking of. This issue was, the other women in society felt too afraid to stand up for themselves as Edna did. Unfortunately, it eventually led Edna into the darkest state of mind. Eventually, Edna feels isolated from society, loved ones, and herself. Which leads Edna out into the sea where A bird with a broken wing was beating the air above, reeling, fluttering, circling disabled down, down to the water (Chopin, 116) with her. The broken-winged bird symbolizes Ednas failure to fully free herself from this society. Ednas wings were too weak to hold herself up above the water before fully submerging. Edna, throughout the story, is seen trapped within a male dominated society, where she is unable to escape. Edna was seen willing to take any risky actions just to free herself from this society. This is why critics describe Edna as a rebellious and selfish adult. Never did Edna have a care for her children, Edna only thought of herself escaping from society. Overall, the birds symbolize Ednas female figure in society which provides a greater mean of emphasis on the progression of Edna throughout the story. In the end, it becomes clear that Edna has no means to fully assimilate herself with the ideal of society. This concept leads Edna to the pigeon house where she is able to eventually overcome the strength of the social and religious conventions that entrap her. However, it is Ednas isolation that leads Edna into her eventual awakening. It becomes clear that each bird was representing a new stage of Ednas awakening into reality. Ultimately, Edna moves into the pigeon house, which provides Edna with the comfort and security the old house lacked. The pigeon house proves to hold great importance in Ednas awakening journey because it signifies her quest for freedom and removal of herself from social order. The pigeon house allows Enda to feel, think, act, and dress how she wants too, without the worry of society. Unfortunately, Edna still s truggles with leaving behind the society she was stuck in. Edna still had her husband, her children, her friends, and her other lovers that trapped her from every leaving. Due to Ednas imprisonment in this society, it lead to Ednas wings becoming too weak to hold herself up anymore, thus, leaving Edna to drown in her own worries.

The Yellow Wallpaper and the Tell Tale Heart Analysis

Hawkins 1 Deidre Professor Connors English 102-15 March 12, 2011 Narrative Unreliability and Symbolisms in â€Å"The Tell -Tale Heart† and â€Å"The Yellow Wallpaper† â€Å"The Tell -Tale Heart† by Edgar Allan Poe, was released in 1843. It is one of Poe’s shortest stories and provides a look into paranoia and mental deterioration. â€Å"The Yellow Wallpaper† by Charlotte Perkins Gilman, was released in 1899. This story also provides a look into mental deterioration and had been misinterpreted when it was first published. The Poe and Gilman stories discussed in this essay will help readers comprehend the credibility of the narrators and the different symbolisms used to create informative yet suspenseful content. In â€Å"The Tell -Tale Heart,† Poe†¦show more content†¦He laughs at me so about this wallpaper!† (Gilman, p327) The credibility of the narrators in both stories is very unreliable. In â€Å"The Tell Tale Heart†, the narrator is giving demonstrations of what he believes to be reasonable. â€Å"Now this is the point. You fancy me mad. Madmen know nothing. But you should have seen me.† (Poe, p37) It makes the reader wonder if the character of the narrator is beliveable because he is able to recall the events, or is he truly mad. The narrator is telling his story as if it were a one on one session, which can make it believable and then we begin to separate the madness from the â€Å"actual† events that occurred. While Gilman has written her story as the form of journal entries, this also alters the credibility of the Hawkins 3 narrator because we only know what she wants us to know, resulting in leaving out important facts. â€Å"I did write for a while in spite of them; but is does exhaust me a good deal---having to be so sly abut it, or else meet with heavy opposition.† (Gilman, p326) She is not honest about writing with her husband, and this proves that she is more than willing to tell her story her way. The symbolisms greatly have an impact on the suspense in each story. Gilman uses wallpaper to symbolize some sort of text she must interpret and believes it affects her in some way directly. â€Å"There are things in the wallpaper that nobody knows about butShow MoreRelatedFiction Essay: Yellow Wallpaper and Story of the Hour1517 Words   |  7 Pagesï » ¿Victoria Reyes English 104-OL5 Professor Steiner September 9, 2013 â€Å"The Yellow Wallpaper and Story of The Hour: A Character Analysis† Marriage has often been described as one of the most beautiful and powerful unions one human can form with another.

Failure of the Belmont Report - 847 Words

One. The Belmont Report has failed to distinguish different sources including the kinds of vulnerability or to map particular protections to particular vulnerabilities (Rogers Lange, 2013). This can be a problem because different kinds of vulnerability justify different responses. Nickel (2006) claims that there are two overlapping senses of vulnerability at work with the Belmont Report and in following human research ethics guidelines (p.2141). The first relates to the capacity to give informed consent, which the Belmont Report connects to the principle of respect for autonomy (Nickel, 2006). The second is the sense of vulnerability, as explained by Nickel, which relates to the Belmont Reports principles of justice meaning fairness (Nickel, 2006). The concern here is that vulnerable groups may be overrepresented in research for example, when the group lacks understanding or power to refuse participation (Rogers Lange, 2013). This is explicit in the Belmont Report. Within t he study, it was also explained that vulnerable groups may be excluded from research and thereby be excluded from the benefits of participation in clinical trials and subsequent access to treatments for which research evidence exists (Nickel, 2006). Research ethics guidelines that simply list groups likely to be vulnerable run a risk of stereotyping, and of the consequent harms of unjustified exclusion of research (Rogers Lange, 2013, p. 2141).

Incremental and Radical Innovation Free Essays

In recent years, the importance of innovation in business cannot be emphasized too much. Along with rapid economic development, the cooperation having innovative ability enables them to own a place in this competitive society. In order to achieve the goal of survival, the firms need to understand the different types of innovation from incremental innovation and radical innovation for those firms who guarantee with the product quality, the lower cost and increasing profits. We will write a custom essay sample on Incremental and Radical Innovation or any similar topic only for you Order Now Following this essay, the difference between incremental and radical innovation are the distinctness of change level of technology and the difference of effectiveness. Following this essay, the effectiveness of two different types of innovation and an example of each types would be explanatory. Innovation can be used in invention or improvement of products, production process, organization and staff creativity. According to the change level of technology , there are different types of innovation, one is incremental innovation and the other is radical innovation. Utilizing which types of innovation depends on what kind of conditions does a cooperation faces. Different consequence would be reached while adopting these two types on innovative system. To begin with, the definition of incremental innovation is ‘doing what we do but better’ (Tidd, Bessant, 2009, p. 27). It usually bases on improvement or boost the existing technology, products or process for maintaining the competitiveness of specific market. Adopting incremental innovation could results in enormous cost saving through upgrading or improving old products or service. Stamm,2003,p260) . In terms of reduction of inefficiencies and waste, which could benefit company from saving money, resources or time. Also this effectiveness from incremental innovation could benefit not only cooperation, but also customers. For example, a famous US airplane company – American Airlines Incorporated (AA). In 1986, when AA had faced a downturn trend with profits, they cut a signific ant cost on their on board meal. (Maynard 2005). Their crew found out that 72% of passengers do not use olive in their salad catering from airplane. The price of salad was included five items, if they change their ingredients of food without olive, it can save $500,000 cost annual year. Since this incremental innovation had reduced the operating cost significantly, increasingly amenities had been cut for less spending such as playing cards, postcards and some toys for children. Although this type of innovation cannot bring new income directly, it does not mean it cannot save a enormous money. Compared with incremental innovation which means doing what we do better, the radical innovation refers to do something different. (Tidd, Bessant, 2009, p. 7) Radical innovation is the revolutionary change in technology or market. To make a breakthrough on the limitation of current technology and production capability , which could strengthen and sustain a firm’s leadership in the market. Moreover, a radical innovation could change current competitive condition, creating a new market and making more opportunities for much benefits and profitability . For example a light emitting diode-LED which is a major device in current life. (It would be finished next time) These two different types of innovation are used in different conditions. Incremental innovation is generally a short-term innovation. On the other hand, radical innovation would continue more longer, usually over 10 years, referring to an high risk investment. Furthermore, radical innovation requires ability of high level of technology innovation, which means it need a relative large expense of investment rather than that of incremental innovation. (Ten3 Business e-Coach 2004) To sum up, in this changing commercial environment, each company should keep learning and carrying out knowledge of innovation to achieve their commitments with profits growth.

Cfcs Cause Deterioration Of The Ozone Layer Essay Example For Students

Cfcs Cause Deterioration Of The Ozone Layer Essay Cfcs Cause Deterioration of the Ozone LayerThe deterioration of the ozone layer , caused by Cfcs, endangers thelives of humans. Cfcs have a diminishing effect on the ozone layer. Furthermore, the deterioration of the ozone cause an increase of Ultraviolet(UV) radiation which can have a negative effect on human skin and eyes. As awriter for newsweek, I have investigated the scenario and found the followinginformation. The earths atmosphere is a blanket of air that surrounds the planet. This atmospheric air is made up of many different gases, 78% nitrogen, 21%oxygen, and 1% of a dozen or more other gases like carbon dioxide, helium, andozone. This atmosphere extends many miles out from the earths surface. However, this layer is not a uniform layer, from top to bottom. As one movesout from the planets surface the atmosphere becomes progressively dense. Thisatmosphere can be divide into four major regions. The first region is the troposphere which extends about 6.5 miles abovethe planets surface. The troposphere contains the oxygen that we breath and iswhere a majority of our weather takes place. Beyond the troposphere is the second region of the atmosphere, thestratosphere. The stratosphere extends from roughly 6.5-30 miles from theearths surface. The air on this region is much less dense than in thetroposphere, and its a lot drier. The stratosphere is the area that containsthe majority of the ozone layer. Past the stratosphere is the mesosphere which extends to 50 miles abovethe planet. The last region is the thermosphere. The thermospheres outermostedge is roughly 600 miles above the surface of the earth. Beyond it, theairless vacuum of space begins. Oxygen is made up of two oxygen atoms that are bonded together. In theperiodic table it is represented by O2. Like oxygen, ozone is a gas that is made up of oxygen atoms. However,a molecule of ozone is made up of three atoms of oxygen bonded together,therefore, O3, represents ozone. The ozone makes up only .01% of the atmosphere. Furthermore, 90% of the ozone is found in the stratosphere. It is concentratedin a layer between 7 and 22 miles above the earths surface. The massive depth of the ozone in the stratosphere would lead you tobelieve that it is very thick, it is not. If it were condensed, the ozonelayer would only be a few millimeters thick (Rowland and Molina 1994. p.23). The ozone is made in the stratosphere. It is continuously being formed,broken down, and reformed, over and over again. Furthermore, the three keyelements of the cycle are: oxygen, ozone, and the energy from the sun. The ultimate source of energy for our planet is the sun. This energytravels through space in the form of Electromagnetic Radiation. Furthermore,this electromagnetic radiation is often referred to as waves and their length,therefore, wavelengths. The sun has a wide range of wavelengths. This range isknown as the Electromagnetic Spectrum. In this spectrum there is Gamma,Ultraviolet, Visible, Infrared, and Radio waves. It is the ultraviolet (UV) radiation coming from the sun that drives theozone cycle in the stratosphere. When a oxygen molecule is hit by a high-energyUV ray, the O2 molecule absorbs the rays energy. As a result, the bond holdingthe oxygen molecule together breaks. This break separates the molecule, O2=O+O. These separate molecules quickly join with nearby oxygen molecules to form aozone molecule, O3=O2+O. Simultaneously, ozone molecules are being hit, theyabsorb the rays energy and break apart, leaving behind an oxygen molecule and asingle oxygen molecule, O3O2-O. At this time, the entire process repeatsitself making new molecules that are separated which combine to make newmolecules, over and again (Rowland and Molin 1991 p. 42). As a result of this cycle, about the same amount of ozone is produced asis broken down in the stratosphere. Therefore, the amount of ozone stays thesame under normal circumstances (Rowland and Molina 1991 p.43). A constant and stable ozone layer are important for life on earthbecause the high-energy UV rays that are absorbed in the ozone layer areextremely dangerous. These rays can kill some things while seriously damagingothers. For example, some bacteria exposed to UV rays will die. Plants, onland and in oceans, can be seriously damaged or even destroyed by UV rays. Whenhumans are exposed to the powerful rays, their skin can burn, damage to the eyes, and permanent changes in cells that can lead to cancer and other problems canoccur. By absorbing the UV rays, the ozone molecules in the ozone layer form ashield that protects life on earth from the dangerous and even deadly UV rays. Gaining the Respect of Others EssayIn the US there were 500,000 cases of the first, 100,.000 cases of the second,and 27,000 of the third type, in 1990(Wayne p. 47). Furthermore, cases ofmelanoma have been estimated to be increasing at an average of 10% from 1979 to1993 and even larger increases are believed to be occurring in the southernhemisphere. Also, studies suggest that a 1% decrease in stratospheric ozonewill result in a 2% increase of skin cancers (Wayne p.49). Moreover, some ofthese skin cancers can result in death. Malignant melanoma is much moredangerous, however, they are the least common. Malignant melanoma effects thepigment cell in the skin which can spread rapidly to the blood and lymphaticsystem. Furthermore, Wayne says, these have become increasingly frequentthroughout the world, especially in areas of higher latitudes. Moreover, thereis a correlation between melanomas and exposure to UV. Melanoma incidence iscorrelated with latitude, with twice as many deaths (re lative to statepopulation) in Florida or Texas as in Wisconsin or Montana(Wayne p.50). Furthermore, melanomas can take up too 20 years to develop, therefore, time willgive us a better example of the effects of increased UV rays have on the skin. The eyes are also affected by UV rays. An increase in UV rays results in an increase of UV absorption by theeye. Chronic UV exposure has been shown to be a factor in eye disease, saysRoach. Moreover, blindness from cataracts is the number one preventable causeof cataracts (Roach p.119). The latest findings indicate that for every 1%decrease in ozone levels results in a .6-.8% increase in eye cataracts, orannually approximately 100,000 to 150,000 additional cases of cataract-inducedblindness worldwide (Roach p.122-3). Moreover, UV rays cause other eye injures including photokeratitis, alsoknown as sun blindness or snow blindness, damage to the retina, and intraocularmelanoma tumors. Roachs predictions suggest a substantial future increase ineye cancer rates. However, some, object to the effects Cfcs have on the ozoneand on humans. Two of the more common objections are: Cfcs are two heavy to reach thestratosphere and we should not be concerned about Cfcs because the majority ofchlorine in the atmosphere is created by the acidification if salt spray. However, for the first objection, atmospheric gases do not segregate byweight in the troposphere and the stratosphere. This is because verticaltransport in the troposphere takes place by convection and turbulent mixing,says Wayne. Furthermore Wayne says, in the stratosphere and in the mesosphere,it takes place by eddy diffusion, the gradual mechanical mixing of gas bymotions on smaller scales, these mechanisms due not distinguish molecularmasses (Wayne Ch. 4). As for the second objection, it is an assumption that is not correct atall. Eighty percent of the chlorine found is from Cfcs and other man madeorganic chlorine compounds (Rowland 1989 p.77). In conclusion, despite the increasing list of negative affects of UVradiation, we continue to release ozone depleting chemicals into the atmosphere. Despite the availability of safer alternatives, we continue to promotetechnologies that are only slightly safer than the ones they replaced. Despiteall of the current information on the destructive affects of Cfcs, we stillcontinue to use them on a mass scale. Scientific research has only began to discover the impacts of UVradiation, however, what we do know should be enough for action. We cannotafford to sit around and wait for the damage to reach a point that makes usreact, by then it will be too late. The time to act is now because even with an immediate and complete endto production and release of ozone-depleting substances to the environment, weare still left with many decades of decreasing ozone and increased UV exposure. We must think long term and act now. Works CitedFarman, J.C., B.G. Gardiner, and J.D. Shankin. Large losses of total ozone inAntarticareveal seasonal CIOx/NOx interaction.
