Paulo Freire, Pedagogy of the Oppressed Essays

Paulo Freire, Pedagogy of the Oppressed Essays Paulo Freire, Pedagogy of the Oppressed Paper Paulo Freire, Pedagogy of the Oppressed Paper Everyone has a different way of learning. Some enjoy listening to lectures and taking notes, others enjoy having a hands-on learning experience, and there are other people that enjoy doing both.I will be discussing two learning techniques that Paulo Freire discussed in his analysis of a teacher-student relationship entitled, Pedagogy of the Oppressed. One of the techniques discussed is called the banking concept, and the other is called the problem-posing method. I willfirst discuss the concept of banking, where you have the students as depositories and the teacher is the depositor.With the teacher, or educator, as the narrator in the classroom, the students are lead to memorize what is said.For example, the educator may say, The square root of 100 is 10.Later, when asked what the square root of 100 is, the students will respond with the answer 10, without knowing how they got the response.To the teacher, the more information that is fed to the students, the better he or she is as a teacher. In education, there must be a solution of the teacher-student contradiction, but this solution cannot be found in the banking concept.In contrast, this banking system maintains the contradiction through the following practices: (1) the teacher teaches and the students are taught, (2) the teacher knows everything and the students know nothing, (3) the teacher thinks and the students are thought about, (4) the teacher talks and the students listen, (5) the teacher disciplines and the students are disciplined, (6) the teacher chooses and enforces his choice, and the students comply, (7) the teacher acts and the students have the illusion of acting through the action of the teacher, (8) the teacher chooses the program content, and the students adapt to it, (9) the teacher confuses the authority of knowledge with his or her own professional authority.

Strain Transformation Essays - Solid Mechanics, Tensors, Free Essays Strain Transformation California State University, Northridge College of Computer Science and Engineering Department of Civil and Manufacturing Engineering STRAIN TRANSFORMATION Submitted to: Nazaret Dermendjian Submitted for: Applied Mechanics 340 Date requested: April 6, 1999 Date due: April 27, 1999 Date submitted: April 27, 1999 The following report will be on Strain Transformation. Strain transformation is similar to stress transformation, so that many of the techniques and derivations used for stress can be used for strain. We will also discuss methods of measuring strain and material-property relationships. The general state of strain at a point can be represented by the three components of normal strain, x, y, z, and three components of shear strain, gxy, gxz, gyz. For the purpose of this report, we confine our study to plane strain. That is, we will only concentrate on strain in the x-y plane so that the normal strain is represented by x and y and the shear strain by gxy . The deformation on an element caused by each of the elements is shown graphically below. Before equations for strain-transformation can be developed, a sign convention must be established. As seen below, x and y are positive if they cause elongation in the the x and y axes and the shear strain is positive if the interior angle becomes smaller than 90. For relative axes, the angle between the x and x' axes, q, will be counterclockwise positive. If the normal strains x and y and the shear strain gxy are known, we can find the normal strain and shear strain at any rotated axes x' and y' where the angle between the x axis and x' axis is q. Using geometry and trigonometric identities the following equations can be derived for finding the strain at a rotated axes: x' = (x + y)/2 + (x - y)cos 2q + gxy sin 2q (1) gx'y' = [(x - y)/2] sin 2q + (gxy /2) cos 2q (2) The normal strain in the y' direction by substituting (q + 90) for q in Eq.1. The orientation of an element can be determined such that the element's deformation at a point can be represented by normal strain with no shear strain. These normal strain are referred to as the principal strains, 1 and 2 . The angle between the x and y axes and the principal axes at which these strains occur is represented as qp. The equations for these values can be derived from Eq.1 and are as followed: tan 2qp = gxy /(x - y) (3) 1,2 = (x -y)/2 [(x -y)/2]2+ (gxy/2)2 }1/2 (4) The axes along which maximum in-plane shear strain occurs are 45 away from those that define the principal strains and is represented as qs and can be found using the following equation: tan 2qs = -(x - y) / 2 (5) When the shear strain is maximum, the normal strains are equal to the average normal strain. These values are determined from the following equations: gmax / 2 = [(x - y) / 2]2 + (gxy / 2)2}1/2 (6) avg = (x + y) / 2 (7) We can also solve strain transformation problem using Mohr's circle. The coordinate system used has the abscissa represent the normal strain , with positive to the right and the ordinate represents half of the shear strain g/2 with positive downward. Determine the center of the circle C, which is on the axis at a distance of avg from the origin. Please note that it is important to follow the sign convention established previously. Plot a reference point A having coordinates (x , gxy / 2). The line AC is the reference for q = 0. Draw a circle with C as the center and the line AC as the radius. The principal strains 1 and 2 are the values where the circle intersects the axis and are shown as points B and D on the figure below. The principal angles can be determined from the graph by measuring 2qp1 and 2qp2 from the reference line AC to the axis. The element will be elongated in the x' and y' directions as shown below. The average normal strain and the maximum shear strain are shown as points E and F on the figure below. The element will be elongated as shown. To measure the normal strain in a

Design for Environment - Assignment Example Also the regulations for environmentally friendly cars, the improvements in design of these green cars, the emission characteristics have been discussed. I. Recyclable household items: According to an article by Kat Long (2010), the most commonly recyclable house hold items are paper , cardboard, plastic, metals, glass, E- wastes, printer cartridges and batteries. Plastics: Recycling of plastic wastes has become a prime concern due to poor biodegradability of the materials used. According to Achilias.D. et al (2008), â€Å"Polyolefins (LDPE, HDPE, PP) are a major type of thermoplastic used throughout the world in such applications as bags, toys, containers, pipes (LDPE), houswares, industrial wrappings and film, gas pipes (HDPE), film, battery cases, automotive parts, electrical components (PP).† While the condensation polymers can be easily recycled, the addition polymers like PET (Poly Ethylene Terephthalate) are difficult to recycle (Karayannidis and Achilias, 2007). Achili as and Karayannidis (2004), propose a thermochemical recycling called pyrolysis that produce liquid form like gasoline. Sustained Plastic waste management involves the mechanical or chemical methods in which the polypropylene and polyethylenes are converted into useful end products. In mechanical recycling, the polymer is dissolved in a solvent and is separated. Achilias.D. et al (2008) claim that the polymer recovery can be greater than 90% by the choice of proper solvents. The end product quality has been examined by Fourier Transform – Infra Red (FTIR) and Differential Scanning Calorimetry (DSC). The end products of these recycling methods include hydrocarbon gases and oils, which can be again reused as feedstock in petrochemical plants. E – waste: E wastes are primarily the old unused computers, cell phones and other electronic gadgets. In the official website of Apple, ( iMac and the environment, ) , it is stated that the challenging task faced by the computer ind ustry with respect to environmentally friendly design is the use of materials involving mercury, arsenic, phthalates, brominated flame retardants (BFRs), PVC in their products and copper wires. The first E-waste recycling was introduced in Switzerland and later followed by the European Union with the â€Å"Waste Electrical and Electronic Equipment Directive† (WEEE Directive, 2002/96/EC). One crude method of recycling the wires include burning the wires together to extract copper from them. Researchers say that these crude methods may lead to more contamination of air, soil and water. This drives the manufacturers of electronic goods to opt for environmentally friendly materials like mercury free backlighting and display glasses that are free from arsenic. Also choosing materials that are thinner, smaller and lighter enables lesser materials to be used. This reduced usage of materials leads to lesser green gas emissions. (The story behind Apple’s environment footprint, www.apple.com/environment/ ). The manufacturers also undertake a complete life cycle assessment of the product with respect to environmental factors. They also use hybrid methods that save energy by reducing the consumption of energy. For example, Apple proposes three techniques for reduced energy consumption. They are efficient power supply, proper power management and using low

Friendship and companionship - Essay Example It clearly shows how close two friends can be. The author was attracted to Queequeg because of his traits and unexpected behavior which is child like and got attracted and started observing his funny behavior by staring at him. His mental ability was so less that he can count only up to fifty. Then he starts counting from one again. By the understanding of the story it is clearly evident the kind of friendship between an innocent friend and a person with good presence of mind. Friends can be so close that they can share literally any thing between them from money to clothes. The story can be a lesson to the friends who regularly argue and fight every now and then. An eye opener, an ideal character, goodness and loyalty at heart. In today's age where gay couples are expressing their love openly, friends like Queequeg and the author are so intimate with each other but with out creating situations like Gay couples. The story idolizes that even money cannot part two friends. For example: when Queequeg took his thirty cents of silver from his pocket and mechanically divides then into half and puts in the pocket author. The author was actually spell bound with the gratitude of the Queequeg. Friends can be so close at times that they share the same bed together. A friendship like this can make an atheist to pray to god.

Redemption exercise (finance management) Essay Example | Topics and Well Written Essays - 1000 words

Redemption exercise (finance management) - Essay Example (c)Oak plc uses a ‘moderate matching policy’ for the financing of its non-current assets and working capital. Using the diagram below, which shows a moderate matching policy explain the meaning of the term ‘moderate ‘in relation to financing of assets and distinguish a moderate matching policy from (i) an aggressive policy and (ii) a conservative policy. (10 marks). Moderate matching policy calls for matching assets and liabilities maturity. That is all of the fixed assets plus the permanent current assets are financed with long term capital, but temporary current assets are finance with short term debt (Brigham & Ehrhardt, 2013). It is policy that enables firms to finance some of its permanent assets with short term debt. That is, all of the current assets – fluctuating and permanent current assets- and part of non-current assets are financed with short term credit. a) Factoring is a means of utilizing accounts receivables to generate cash flow by selling them to a factor and thereby effectively converting credit sales to cash sales. The buyer of the goods is notified to make payments to the factor. Invoice discounting is the provision of finance against the security of a certain percentage of receivables. The title to the invoice and the rights to the proceeds remain with the seller. The financier will purchase a company’s invoice at a discount but the management of receivables and collection will remain with the company (Brigham & Ehrhardt, 2013). (c)Describe the effect overtrading would have on the main accounting ratios. (You may wish to consider the following ratios: acid test ratio, inventory days, trade receivable days, trade payable days and current ratio) (10 marks) The growth in sales volume increases the inventory and receivables. This will affect the working capital management efficiency leading to an increase in the trade receivable and

Hip-hop music Essay Example for Free

Hip-hop music Essay Hip-hop music, according to Joan Morgan, is a powerful force in popular culture. However, she also criticized how hip-hop â€Å"repeatedly reduced me to tits and ass and encourages pimping on the regular. † Emphasis is given on how machismo and sexism prevail in the lyrics of hip-hop music. As is seen in various examples highlighted in Morgan’s article, hip-hop music taught men to treat women without the respect and love that they deserve. They came to learn to treat women as objects to fulfill sexual desires, calling them â€Å"bitches† and â€Å"hos†. It is seen in hip-hop music how women use sex as a weapon to gain material wealth and protection, not because they want it, but because it is the only option they have. This only shows how women are, in modern times, still victims of gender inequality. Over and over again, these themes have been the topic of hip-hop music, along with â€Å"alcoholism, substance abuse and chemical dependency. † After all, hip-hop music has done much to encourage these acts unbecoming of decent people. However, Morgan also suggested it as a part of a more complex problem, stemming from the racism experienced by black people. All these talks about sex and drugs and crimes are reflections of the bitterness, the hurt that the black people feel, resulting to more damage. According to Morgan, crimes committed against black people, are more likely done by black people themselves. White people are long ago out of the question. Depictions of a violent and cruel world where everything can be bought by money and sleeping with a rapper will give you a record contract gives them self-satisfaction and a self-liberating feeling when they play master and the women their slaves. But deep inside they do not feel real happiness as they fail to face their problems and responsibilities in reality. In the end they continue to feel empty. Take for example the music video of the song â€Å"Gold Digger† by Kanye West and Jamie Foxx, which topped the charts at the time of its release and even won a couple of Grammy Awards. The video alternates with scenes of West and Foxx singing, women wearing skimpy lingerie making poses for men’s magazines, and women dancing all over the men. These depictions of women in the video did not give any love, let alone respect for women in general. They are merely seen as objects of desire that can be bought anytime of the day. There are also some scenes in the music video wherein the men are dragged into a dark room where all the women wearing lingerie are present. They are represented as nothing more than â€Å"bitches† and â€Å"hos† only after these men for their money. As it is, these women are depicted to give sex to those who can pay, and even trick some of the richer guys into marrying them. One scene in the video even spelled out the word â€Å"pre-nupt† as the men supposedly wanted pre-nuptial agreements before marrying these women so that they can’t touch a cent of the men’s money. Even the lyrics of the song, sung in the point of view of a rich husband, describes how his wife tricked him into marrying him by saying that she’s pregnant with his son, but after eighteen years, he found out that he was not the real father of this child. Now that he wants a divorce, half of his assets will go the cheating wife. Nevertheless, the â€Å"kid† in the video was white and not black, a direct allusion that it is not his child. His perpetrator was â€Å"white†. This not only shows how lowly they think of women but of how they are forced to do these things so that they can have financial and emotional security that they cannot in themselves achieve because they are prevented from doing so. Women themselves are deprived of the love and care they need as the men continually search for physical love and satisfy their egos in order to forget their own worries and problems. In a deeper context, â€Å"Gold Digger† tries to disguise the hurt of being fooled, of being cheated, by bragging that yes, she’s a gold digger, I’m rich and I can afford to buy any girl I want. The video did not objectify men and women. The difference in the treatment of men and women can be seen in the whole video. In a sense, the men are the customers, and the women, mere products they could buy and use at their whims. As Morgan puts it, it is not about calling women â€Å"bitches† or â€Å"hos†, but men’s incapability to show love. They treat women as some kind of objects because it is the only way that they can feel powerful. This incapability to love proves Morgan’s point that these men are hurt. The pain has taken something very special from them, and that is the ability to love and to care for others. The distrust for women shown in â€Å"Gold Digger† is there, in the first place, because these men are afraid, afraid to love and get hurt in the process. But because of this loss, women became victims of abusive treatment. One lesson that can be learned is that love per se is not synonymous with sex. According to Morgan, we all should learn to address our issues and better treat each other. We should eliminate all the barricades caused by the depiction of women in hip-hop music and eliminate the confusions. As mentioned earlier, hip-hop has a big influence on popular culture. What we hear, we incorporate in our minds and way of living. We can use this influence to create hip-hop music that loves, respects, and most importantly, hip-hop music that forgives.

Benefits Of Technology In Business

Benefits Of Technology In Business The term Technology is derived from the Greek word Technologia techne means craft and logia means the study of something. Technology is a very broad concept and is used to refer to several braches of science and study. Some examples are information technology, medical technology, biotechnology, etc. As the term technology branches into various fields of science and study, so do its benefits. Let us look at the benefits of technology in some major areas of day-to-day life: Benefits of Technology in Business: The days when the Chief Information Officer (CIO) took implementation decisions and passed the responsibility down the line are passà ©. Today, the CIO is an individual who possesses business as well as technical skills, understands the new IT issues facing a business, and drives the IT changes from the top down. This is a clear indicator of the benefits businesses are enjoying through the implementation of technology. Today technology is an integral part of any business right from the purchase of computers and software to the implementation of network and security tools. This helps businesses to: Remain up-to-date Drive business forward Sustain and survive competition In short, technology has become one of the significant factors that maximize an organizations ROI. Benefits of Technology in Communication: From hand-held computers to touch phones, technological advancements in the field of communication are endless. The means and the modes of communication are unlimited. Some of the benefits of technological advancements in the field of communication are: Speed time is no longer a constraint in communication Clarity With megapixel images and video, and high fidelity audio systems clarity in communication has become a never-before experience Proximity technological advancements have made the world a smaller place to live in Dissemination whether spreading information, broadcasting news, or sharing knowledge, technology has made it faster, easier, and smarter Benefits of Technology in Education: Technological advancements in the field of education are fast evolving. Today, e-learning is a familiar and popular term. Some of the benefits of technology in this field are: Personalized learning experience: Learners are able to take control and manage their own learning. They set their own goals, manage the process and content of learning, and communicate with peers. Immediate response: Most e-learning programs provide immediate feedbacks on learner assessments. Similarly there are features such as chat, discussion boards, e-libraries, etc that allow clarifications at a faster pace than in traditional classrooms. Self-paced: Learners can chart courses at their own pace. This ensures higher levels of motivation both in terms of completing the course as well as in performance. Greater access: Technological advancements have opened education to learners with learning disabilities and in remote locations. Benefits of Technology in Healthcare: The marriage between medicine and technology has reshaped healthcare and revolutionized the medical profession. Some of the major benefits are: Secure environment: Technology allows physicians and patients to interact in a secure and comfortable environment to discuss sensitive issues. Flexibility: Physicians can answer routine and less critical queries at a convenient time. Cost- and time-saving: Physicians can follow-up, provide advice, and re-direct patients to resources on the Internet. This saves cost and time by reducing office visits. Medical devices: Medical aids allow patients to continue recovery at home reducing their hospital stay. Vulnerable population: Technology aids the very young, elderly, and patients with complex birth defects, chronic illnesses, and disabled children by alleviating their problems so that they can continue living in their homes. Benefits of Technology in Society: Today technology pervades almost all aspects of our daily life from shopping, banking, making travel arrangements to university admissions. Some of the benefits are: Convenience: Provides a great deal of convenience in expediting personal and business transactions be it shopping, banking, or simply paying bills. Speed: From sending gifts to making payments everything gets a done with a few clicks. Communication: The world is a smaller place and technology allows everyone to keep in touch with their families and friends at a more affordable cost. Accuracy: Technology has reduced errors in mundane and monotonous chores, saving time and cost. Development: Technology has brought about development in many fields such as medicine, government, business, education, etc. Technology has evolved and transformed our lives and society. Overall, it has brought about tremendous growth and benefit to mankind. What Are the Benefits of Technology in Business? Whats This? Technological advances in the past few decades have greatly increased the competitive nature of the economic business world. Companies have used software, computers and the Internet to transform their businesses from local places of business to national and global market competitors. Many companies have responded to these changes by automating their business processes and capturing industry-related information and using it to their advantage. Technology has also forced businesses to remain flexible, adapting their operations to newer and better technological advances. Better Reporting Functions Companies that have multiple locations, whether nationally or globally, have used technology to implement better communication services and software modules that communicate to a home base via the Internet. This allows companies to penetrate new economic markets without sacrificing the needs of communication or financial and operational reporting. Additionally, companies can improve their management information system (MIS) to capture information for specific locations when making business decisions. Financial reporting has also benefited greatly from technology; rather than sending external auditors to multiple locations, it is possible to create a centralized accounting office to record and report financial transactions. This improves financial reporting and lessens the expense related to external audits. Increased Employee Productivity Computers and business software packages have exponentially increased employees productivity by allowing them to provide data entry functions or review automated reports. Companies have automated several traditional manufacturing processes; instead of using manpower to manually create and assemble goods, machines and/or robots now complete these functions. While these improvements may increase capital expenditures, they lessen the impact of consistent labor expenses related to productions. Fewer employees are needed to monitor the machines and ensure they are working properly. Other areas, such as customer service, accounting and administrative support, have also seen an increase in employee productivity. Employees now review and report electronically collected data to ensure they are accurate and timely, rather than manually gathering information. Improved Business Mobility Technology has also improved companies sales and service departments by allowing employees to use personal electronic devices to create sales displays and transmit orders and customer information to the home office. These electronic devices shorten the lead time companies spend on receiving and delivering goods or services, creating an instant competitive advantage in the industry. Companies can also send sales representatives to multiple markets at the same time, allowing them to penetrate multiple markets with few overhead costs. Companies may allow their internal employees to work from home using a company Internet connection, reducing the fixed overhead expenses from a large corporate office.

Whatever can speed production will draw in more business. As computers emerged in the 20th century, they promised a new age of information technology. But in order to reap the benefits, businesses needed to adapt and change their infrastructure. For example, American Airlines started using a computerized flight booking system, and Bank of America took on an automated check-processing system. Obviously, now, most business is conducted over personal computers or communication devices. Computers offer companies a way to organize dense databases, personal schedules and various other forms of essential information. As information travels faster and faster and more reliably, barriers of distance disappear, and businesses are realizing how easy it is to outsource jobs overseas. Outsourcing refers to the practice of hiring employees who work outside the company or remotely and even halfway across the world. Companies can outsource duties such as computer programming and telephone customer service. They can even outsource fast-food restuarant service dont be surprised if youre putting in your hamburger order with a fast-food employee working in a different country entirely. Outsourcing is a controversial practice, and many believe that U.S. companies who take part are hurting the job market in their own country. Nonetheless, from a business perspective, it seems like the wisest route, saving companies between 30 and 70 percent [source: Otterman]. Another technology thats starting to revolutionize business is actually not very new its just cheaper these days. Radio frequency identification (RFID) technology is infiltrating and changing business significantly in a few ways. Microchips that store information (such as a number equivalent of a barcode and even an up-to-date history of the chips travels) can be attached to product, and this helps companies keep track of their inventory. Some businesses have even begun to use RFID chip implants in humans to tighten security. An access control reader detects the chips signal and permits the employee access to the door. But many people are concerned about privacy issues if this were to become widespread practice. Handheld devices like BlackBerries have become wildly popular for businesses because they let users check and send email from anywhere, and browse the Internet. Internet Business: The Internet enables airlines to provide online flight booking, banks to offer online account management and bill pay and allows any company to sell any product online. In general, the Internet has proven to be an inexpensive way to reach more customers. Nowadays, if you cant find a business online, or if it has an outdated, ugly Web site, it looks downright unprofessional. Many businesses have succeeded in using the Internet as their primary, or sometimes only, medium. (Youre, of course, aware of this, given that youre reading a HowStuffWorks article. HowStuffWorks started as a hobby for college professor Marshall Brain, and it eventually grew into successful company.) Small businesses, too, have become easier to start up using the Internet. If youre a stay-at-home mom who makes a killer batch of cookies, you can easily sell them over the Internet and ship them to your customers. But, its not always as simple as it sounds. Any business conducted online must consider security, privacy or even copyright issues. Copyright issues would include making sure your business doesnt use someone elses original work (such as a logo, for instance) or even making sure no one else is profiting from your businesss creative work. One of the biggest ways the Internet has changed business is through targeted advertising. Using Google, companies can specify the keywords that will drive certain customers to their ad. For instance, if you were to plug the word baking into Google, you might click on a page from epicurious.com. That epicurious page will have Google ads from sponsors who sell baking-related products. A company that sells rolling pins can pay to have its ads show up for people who search for specific words, like baking, pies or dough. It makes good business sense people who search for baking on Google will be much more likely to click on a rolling pin ad than the average person. Despite what weve discussed in this article, we havent even scratched the surface of what new technology can do for business communications. The next page provides links to even more articles on information technology and products that have business implications.
