Theory Essay free essay sample

The Lesson is written by Toni Cade Bambara and is a fictional narrative. The significance of this short story is deepened when we apply Paulo Freire’s story Pedagogy of the Oppressed because he talks about the different kinds of teaching methods that relate to the characters in The Lessons and the society that they live in. In Freire’s story he deliberates about the society we live in, which uses the banking method rather than the problem posing method of teaching. I believe that this is what Miss. Moore is trying to show her students in The Lesson by taking them to the ‘rich’ part of town when they go into the toyshop. In Freire’s story he gives two terms: the oppressor, which in my opinion is the white people in The Lesson and the oppressed which is Sylvia and her classmates. In The Lesson, you meet a young girl who goes by the name of Sylvia. Sylvia is brought up in a ‘slum’ area and is resentful towards her teacher, Miss Moore. Sylvia feels that her teacher is better than everyone else in her community because she has a college degree, and doesn’t care to listen to anything Miss. Moore has to say. The story starts off by Miss Moore bringing the group of children to this toyshop, which is where I believe she is trying to expose them to this banking system concept, to show them what is wrong with their society. The banking system concept is when â€Å"the teacher talks about reality as if it were motionless, static, compartmentalized, and predictable. Or else he expounds on a topic completely alien to the existential experience of the students† (Freire 52). In other words the banking system where the teachers believe only they can be the ‘knowledgeable other’, the knowledgeable other is someone who has more experience and knows what they are doing which makes them the one who holds all the knowledge. They don’t believe the students can teach them anything new. Using this type of system will result in the student’s only being as good as what they’re taught. The problem posing method on the other hand is where the teachers and the students work together, that they can learn from each other and respect one another’s thoughts, ideas, questions and wonders. A great example of the banking method that Freire writes is â€Å"the more completely she fills out the receptacles, the better a teacher she is. The more meekly the receptacles permit themselves to be filled, the better students they are† (Freire 53). In The Lesson the white people are the oppressors and Sylvia and her classmates are the oppressed. Freire explains the oppressed â€Å"The oppressed receive the euphemistic title of â€Å"welfare recipients†. They are treated as individual cases, as marginal persons who deviate from general configuration of a â€Å"good, organized, and just† society† (Freire 55). This is saying how poor people are treated as separate people in society. The students in The Lesson did not know they were seen as this ‘separate’ part of society. According to Freire he doesn’t believe this is the case, he see’s everyone as equals â€Å"The oppressed are not â€Å"marginal†, are not people living â€Å"outside† society. They have always been â€Å"inside† (Freire 55). Once Sylvia and her classmates arrive at this toyshop they notice a toy sailboat that catches them off guard, but it’s not the sailboat, it is the price tag that is attached to it, Sylvia exclaims â€Å"Who are these people that spend that much for preforming clowns and $1000 for toy sailboats? What kinda work they do and how they live and how come we ain’t on it? (Bambara 425). I believe that by bringing the children to this new environment she was trying to open the children’s eyes to this ‘separate’ society. Miss Moore embodies the idea of problem posing. From Freire’s point of view, a teacher that poses these traits should â€Å"from the outset, her efforts must coincide with those of the students to engage in critical thinking and the quest for mutual humanization† (Freire 56). Miss. Moore does this when she asks a question to deepen Sugar’s thought about why adults would play with a kid’s toy. A great metaphoric description between the two methods that Freire uses, quoting Fromm is that the banking system causes people to be ‘necrophilia’ versus the problem posing method, which is causing people to be ‘biophilious’. â€Å"While life is characterized by growth in a structured, functional manner, the necrophilous person loves all that does not grow, all that is mechanical. The necrophilous person is drive by the desire to transform the organic into the Memory rather that experience, having, rather than being, is what counts. The necrophilious person can related to an object- a flower or a person- only if he loses the possession he loses contact with the world†¦ He loves control; in the act of controlling he kills life† (Fromm 58). I feel that this quote strengthens the issue that the children have around this expensive boat. In my point of view the children are more biophilious, this is backed up when it shows that they do not see the importance of an expensive boat when they could use that money to feed an entire family. They aren’t bound by materialistic items. During The Lesson you read about Sylvia getting mad at her friend Sugar for engaging in conversation with Miss Moore regarding the toy sailboat. This displays that Sylvia is unintentionally still bound by the banking system because if they were in the problem posing method this would be seen as harmful to one another’s learning. You notice that Miss Moore is trying to get the students to critically think for themselves in a problem-posing manner, but it is apparent that they are all in some matter constricted by this banking system method that they live in. The whole idea of the banking system with the roles of the oppressed and the oppressor is that it stops people from becoming fully human, as Freire says â€Å"no one can be authentically human while he prevents others from being so†.

Potassium Essays - Potassium Compounds, Dietary Minerals

Potassium potassium puh-tas'-ee-uhm The chemical element potassium is a soft, light, silver white metal. It is a member of the alkali metals, a group (IA of the periodic table) with similar physical and chemical properties. Its chemical symbol is K (from kalium, the Latinized version of the Arabic word for alkali). Its atomic number is 19, and its atomic weight is 39.098. Potassium was first made from potash, or potassium carbonate (K(2)CO(3)), which had important industrial uses in glass manufacture well before 1700. (It was often mistaken for sodium carbonate, or soda. Only their different sources prevented total confusion, potash being originally derived from the ashes of vegetable materials, whereas sodium carbonate is most often found as a mineral.) On Oct. 6, 1807, Sir Humphry Davy connected a piece of solid potash to the poles of a battery and caused the release of a metal at the negative pole. He named the metal potassium and determined many of its physical and chemical properties. Chemical Properties Alkali metals are the most reactive metals. In general, their reactivity increases with increase in atomic size. Because of their electron arrangement and relatively large size and small charge, potassium atoms are conducive to ion formation only by ionic bonds. Biological Role Potassium is essential to life. Involved in active transport, the process of moving substances in and out of cells, it constitutes about 0.06% of the atoms in the human body. Whereas sodium ions are found primarily in intercellular fluids, about 99% of the body's potassium lies within the cells. Together, these ions help to regulate cellular osmotic pressure and acidity, or pH, levels. Potassium plays a key role in muscle activity and the transmission of nerve impulses. It is also involved in cellular enzyme functions. An abnormally low level of potassium in blood serum causes cardiac abnormalities, and an abnormally high level leads to a heart attack. Such changes in level, controlled by the kidneys, can result from various diseases. Potassium is present in most food substances, so a potassium-deficient diet is unlikely. Production Potassium is produced in laboratory amounts by electrolytic reduction of fused potassium hydroxide (KOH) or fused potassium chloride (KCl). Other methods include electrolysis of fused potassium cyanide (KCN), heating potassium chloride (KCl) with metallic calcium in a vacuum and distilling the potassium as it is formed, and heating potassium hydroxide (KOH) with iron, aluminum, or magnesium. Because commercial potassium uses are most often also satisfied by more easily recovered sodium, only modest amounts of potassium are produced. One industrial method uses sodium vapor to reduce molten potassium chloride at 880 degrees C. The potassium vapor formed is drawn off and condensed. Potassa potash, from English potash] First appeared circa 1807 : a silver-white soft light low-melting univalent metallic element of the alkali metal group that occurs abundantly in nature esp. combined in minerals potassium Dutch potassa 'potash' Soft, waxlike, silver-white, metallic element, symbol K (Latin kalium), atomic number 19, relative atomic mass 39.0983. It is one of the alkali metals and has a very low density ? it floats on water, and is the second lightest metal (after lithium). It oxidizes rapidly when exposed to air and reacts violently with water. Of great abundance in the Earth's crust, it is widely distributed with other elements and found in salt and mineral deposits in the form of potassium aluminium silicates. Potassium is the main base ion of the fluid in the body's cells. Along with sodium, it is important to the electrical potential of the nervous system and, therefore, for the efficient functioning of nerve and muscle. Shortage, which may occur with excessive fluid loss (prolonged diarrhoea, vomiting), may lead to muscular paralysis; potassium overload may result in cardiac arrest. It is also required by plants for growth. The element was discovered and named in 1807 by English chemist Humphry Davy, who isolated it from potash in the first instance of a metal being isolated by electric current. Science

Massospondylus - Facts and Figures

Massospondylus - Facts and Figures Name: Massospondylus (Greek for large vertebrae); pronounced MASS-oh-SPON-dill-us Habitat: Woodlands of South Africa Historical Period: Early Jurassic (208-190 million years ago) Size and Weight: About 13 feet long and 300 pounds Diet: Plants Distinguishing Characteristics: Large, five-fingered hands; long neck and tail About Massospondylus Massospondylus is a good example of the class of dinosaurs known as prosauropodssmall-to-medium sized, small-brained herbivores of the early Jurassic period whose relatives later evolved into towering sauropods like Barosaurus and Brachiosaurus. In early 2012, Massospondylus made headlines thanks to the discovery in South Africa of preserved nesting grounds, containing fossilized eggs and embryos, dating to the early Jurassic period (about 190 million years ago) This plant-eaterwhich paleontologists believe stomped in stampede-sized numbers across the plains of early Jurassic South Africais also a case study in changing views of dinosaur behavior. For decades, it was widely believed that Massospondylus walked on all fours, only occasionally rearing up on its hind legs to reach vegetation. In the last few years, though, convincing evidence has come to light that Massospondylus was primarily bipedal, and faster (and more agile) than was previously believed. Because it was discovered so early in paleontological historyin 1854, by the famous naturalist Sir Richard OwenMassospondylus has generated its share of confusion, as various fossil remains have been incorrectly assigned to this genus. For instance, this dinosaur has been identified (at one time or another) with such dubious and now-discarded names as Aristosaurus, Dromicosaurus, Gryponyx, Hortalotarsus, Leptospondylus, and Pachyspondylus.

Exercise psychology Essay Example | Topics and Well Written Essays - 2000 words

Exercise psychology - Essay Example Exercise has been reported to reduce one’s feeling of depression and anxiety, as well as upgrading one’s cognitive skill and self appreciation. Any form of conscious activity requires utilizing both the mind and the body, much more if it’s a physical activity like exercising, be it a light or rigorous one. Exercise speeds up circulation of the blood, providing the brain with oxygen that aids in its function. According to Dr. Zeischegg, inadequate supply of oxygen to the brain can lead to poor concentration, mood swings, depressive thoughts, among others. Exercise likewise keeps the mind busy, allowing the person to veer away from whatever negative feelings he or she may be having at that point. It is imperative to add, however, that just like any other activity, exercise has to be done in moderation. Inexperience and lack of valuable information regarding chosen exercise may lead to adverse side effects and/or physical damage, thus, defying its purpose of psychol ogical enhancement. It is also imperative to stress the acknowledgment that depression is not a one-day sickness that goes away after sleeping on it. An excruciating experience or event generally causes depression. This experience or event may have happened overnight but this does not follow that getting over it will happen just as fast. Realizing this fact generally helps the patient realize that overcoming depression needs to be gradual, not forced. Several activities have been considered with reference to enhancing psychological well-being of a person. Frequently considered are running, walking, cycling, and swimming. Since the only given facts in the case study I chose were gender, age, and physical health, I will assume that any of the above-mentioned exercises may be apt for him. Running. â€Å"Running actually has the ability to alter an individual’s moods because hormones called endorphins are released while running†,

It compares based on price and customers review on particular food selected by user. It will help user to find best food nearby his/her location. Main advantage that it brings transparency in price and quality of food is serving in the city. Restaurant owners will provide information about its menu and other information about restaurants like establishment years, experience in this business, connected with another firm and schedule. Restaurant owner can have Owner panel to modify menu whenever they want. The software need GPS (location) permission for find nearby place feature which allow software to calculate minimum distance with user and provide best search result. 1.3 Definitions, acronyms and abbreviations Term Definition user Person who interact with website Admin/Administrator System administrator who have rights to change and manage website information Restaurant owner Who have rights to change own restaurant menu and prices Developer Who created this website and managed all information GPS Global Positioning System GPS-Location Manager Location permission need when website is excessed through user device to improve search optimization Data Source Person or referencing object who contributed data in this website 1.4 Overview In this documentation, we have majorly included three chapter which enable to give brief introduction of system and other interaction modules given by all whole system. In this document, also describe different stakeholders and their respective roles. Another aspect is that what is constrains and assumption need to mention in system that every individual should make is also describe in this documentation. Requirement specification and detailed terms and definitions of the different interfaces mansion in third chapter of documentation. Technologies used during implementation of requirement also mentioned. In the Fourth chapter prioritization of requirement is mention and also mentioned what basis developers are choose those requirement is first and all filtration process. The appendixes in the end include all results of requirement prioritized and launch plan of development. 2. Overall description This section will provide associate summary of the entire system. The system will be explained in its context to indicate however the system interacts with alternative systems and introduce the essential practicality of it. It will additionally describe what kind of stakeholders which will use the system and what practicality is obtainable for every kind. At last, the constraints and assumptions for the system will be given. 2.1 Product perspective This system mainly contain two parts first one is web browser and second is database. Web browser serve application pages which contains different pages to serve. GPS will be used by mobile application to locate user. Distance between user and restaurant will be displayed by GPS and also da of application will be displayed by GPS. User can use function of GPS seamlessly manner. This application contains centralized database so it requires to store data somewhere. Mobile application as well as website both can access to database. They will use database in different ways. Mobile application will use database to display those data which is required by user. Web portal will use database to store and modify those data needed by administration team of system. Internet will be used for this kind of communication. There are limited resources available for mobile application. The maximum amount of hard drive space required by application will be 20 MB. 2.2 Product functions User can search restaurants using mobile application. The result will be displayed using inputs given by user. Administrator of system can change of add criteria. Search result will be displayed in either list view or in map view according to the requirements of user. The list view will have one list item for each restaurant. Location of each restaurants will be displayed in map view. In both views user, can view information about restaurants. The web portal will be used for data population and administration purpose. 2.3 User characteristics The number of types of users is three which will interact with system: User of mobile application, administrators and restaurant owners. Each user carries different role, requirements and rights on system. The mobile application users can see data only. They can input criteria for search restaurants and gets directions to reach there. The restaurant owners will use web portal to populate date. The can manage their menu and information about restaurants. The administrators will use web portal to system. They will have maximum rights on system. They are responsible for removing uncourts data and harmful contents. 2.4 Constraints Mobile application needs GPS system to be functional properly. Mobile devices with different GPS will use same interface. The application will also require internet connection. Connectivity to database is established over internet so internet connection will be needed by application. Both the application and web portal will have limited size of database. Database is shared between both application and web portal so it can happen that they can be forced to queue incoming requests. 2.5 Assumptions and dependencies We can assume that application will be installed on capable devices. If device does not have enough space, then application will not be installed. Another assumption is that all mobile devices in which application is installed, have working GPS with same interface. If the phones have different interfaces to the GPS, the requirements for GPS will needed to be changed. 2.6 Apportioning of requirements If project is about to be delayed, there are some requirements that will be implemented in the next versions of application. Those requirements are to be implemented in the next release, see Appendix IV. 3. Specific requirements The functional and quality requirements are contained by this section. Detailed description of system and interface is given in this section. ÂÂ  3.1 External interface Requirements This section describes all inputs and outputs of system. It also describes the software, hardware and the communication interfaces. This section provides basic prototypes of the user interface. 3.1.1 User interfaces Login page will be displayed to first time user, see Figure 2. User can navigate registration page from login page. Search page will be displayed to user if user is not first time user, see Figure 3. User will select search criteria here and able to get list of required restaurants. User will have profile page to manage personal and contact information, see Figure 4. Also, the user can change its preferred language. 3.1.2 Hardware interfaces Applications are installed on fully built systems so they dont need any external hardware. The GPS and database will be handled by underlying processes of operating system of respected devices. 3.1.3 Software interfaces The mobile application will use GPS to get location of user and will use database to fetch data about restaurants which is required by user, see Figure 1. Mobile application can only read data from database. Web portal will have all rights on data of database. 3.1.4 Communications interfaces The different parts of system are highly dependent on each other so communication among them is very important. Way of communication is doesnt concerned by whole system. So, communication will be handled by underlying processes of operation system on respective devices. 3.2 Functional requirements 3.2.1 User Class 1 The User 3.2.1.1 Functional requirement 1.1 ID: FR1 TITLE: Download mobile application DESC: Application should be downloaded by user from application store and free of cost RAT: So, user can download application.

DEP: FR6 3.2.1.8 Functional requirement 1.8 ID: FR8 TITLE: Admin panel DESC: Administrators should be able to manage database of system. RAT: System management. DEP: None 4. Prioritization and Release Plan 4.1 Choice of prioritization method Top 10 most important requirements will be selected first. This will be done by simple number method in which higher number means high priority. Number will be assigned base on decision of meting of stockholders. The highest summed number associated with requirement will decide priority of requirement. The results will be red marked and others will be left as are they before. These requirements were prioritized according to the points they got and the results can be viewed under Appendix II. 4.2 Release Plan The requirements were divided in three groups and each group will be implements in each release of application. Each release will be work as complete working system. The first release will contain essential requirements. The last release will contains most advanced requirements. Other requirements can be implemented in middle release, Gantt Chart

Separation Or Assimilation? :: essays research papers

Separation or Assimilation? Our country, The United States of America, was essentially founded on the principles of life, liberty, and the pursuit of happiness through solidarity of human kind. In Bernard R. Boxill's article, "Separation or Assimilation," he fundamentally poses the Hamletesque question: to assimilate or not to assimilate. Subsequent to the dilemma of some black cultural nationalists, whom not only argue for assimilation of the black American populace, but also believe that this assimilation into white culture is inevitable, against cultural pluralism. Cultural pluralism, which was initialized by W. E.B. Dubois in the late 19th century, is founded upon the peculiarities of races, living harmoniously in one nation-state, and lacking superiority or inferiority. Consequently to posing this question one dictates that there exist certain boundaries between cultures in our American society. Where do these boundaries come from and are they indeed necessary? Is integration of these cultures indeed inevitable? The goal of cultural pluralism as stated by Boxill are to establish pride in one's own race, to maintain the authenticity of one's own culture, and finally to benefit the world populace. Through pride, the disdain of inferiorities along with self respect, one adopts an attitude of self- segregation. Boxill argues for pride as a means of preserving one's race, overemphasizing differences between individuals because of the color of their skin or cultural differences, is a great defense to assimilation. Understanding Dubois's concept of cultural authenticity is to delve into the mysteries of self-actualization, that is to realize one's own potential. He asks himself, as an African American, whether his true identity lies in the jungles of Africa or in this land of America. He is of the opinion that these are his only two options. He concludes that his true identity goes beyond his American birth, citizenship, political ideals, language, laws, and religion; deep into the heart of Africa where a timeless culture was born and should be preserved for its beauty and used to benefit the world populace. "...the Negro people, as a race, have a contribution to make..."(Dubois,p244) The "Negro people" as a race, have certainly had a peculiar world condition throughout time and have had the ability to lend privileged insights into the human condition. The whole of humanity consists of many parts. From the cultural pluralist perspective, this whole can be benefitted most by the contribution of gifts from each race of humanity. But does not true diversity exist in individual persons rather than in large groups of unique individuals. It would seem obvious that the greatest degree of solidarity of humanity can be achieved
