The Moral Implications of Oretga and Gasset's Account of Barbarism Essay

The Moral Implications of Oretga and Gasset's Account of Barbarism - Essay Example For example, missionaries of humanity civilize savage race by using sword and fire because there is no other method than violence to transform the savage people from their way of life. After applying these violent methods, principles of civilization gradually develops and creates various forms of a human being’s spiritual manifestation that are called philosophy, religion, art and science and other forms of social life that enable an individual to enjoy freedom, security, leisure and self manifestation in greater spheres of activity. Thus barbarism transforms itself into civilization. As mentioned earlier, civilization is the beginning of all principles and ideas and all the knowledge for this transformation comes from the ideas preserved during the previous civilization. However, simultaneous to the beginning of civilization destruction and violence also arises and as a result, barbarism grows along with civilization. The parallel growth of barbarism side by side with the civ ilization can be easily traced in our society. In ancient times, the savage used to kill his enemy and in the cultured times, man has a wide range of technical devices, explosives, aero planes, poisonous gas and submarines to get rid of the enemy. These sophisticated weapons are the modern forms of the club and they are different only in the power and action. These are the civilized means of destruction and this cultured method and means of violence is the culture of barbarism (Ouspensky p.39). Barbarism thus exists in our society in the form of violence to gain control over another state, religion, morals and ideas and in the every other factor imaginable. The basic ambition of a modern society, its interests and tastes comprises of barbaric traits. The passion for competition, gambling, sport and the idea to influence, and behaviors like fear, panic and suspicion are features of barbarism. These features flourish in our daily life through technical culture by means of telegraph, q uick means of communication, wireless telegraphy and the like. Culture has established a differentiation between itself and barbarism. The manifestation of barbarism in the society is called crime. Prevailing criminology is insufficient to separate barbarism because crime is an infringement of law and law are usually a manifestation of violence and barbarism. Though the culture of civilization and barbarism develops simultaneously these two factors cannot sustain in the society indefinitely. A moment inevitably arrives when barbarism stops the development of civilization, and swiftly or gradually, completely destroys civilization (Ouspensky p.40) Why is philosophical barbarism important to the reader? The difference between barbarism and non barbarism is. Ortega y Gasset implicates that the people in modern society has the right to change and impose law directly. The common man has freedom to proclaim the rights and impose them wherever necessary. This indirectly means that common m an can control the process of civilization even if there is no progress in it. It is indeed extremely complex to preserve the current civilization that requires incalculably subtle powers. Even if a person is unfit to change the civilization, the common man has learned to utilize the advantages of the machinery built by the civilization by ignoring the principles of the civilization. The command of leaders over the public even though they are intellectually vulgar is not acceptable to culture because

Media Shaping Women Essay

The media has clouded women’s perceptions in their body image by demonstrating the ‘ideal bodies’ on TV and magazines through print and film advertising, increasing the pressure for women and young girls to be ‘thin’, further leading to a more complex issue of Eating Disorders. Women who do not live up to societies expectations, and are suffocated with the phoney concept of the ‘ideal’ are treated with disregard and discrimination. For instance, Adrian Furnham and Nicola Greaves (1994) argue that the core of body image dissatisfaction is a discrepancy between a person’s perceived body and their ideal. They further argue that a failure to match the ‘ideal’ leads to self- criticism, guilt and lowered self worth. This effect is stronger for women than for men due to the cultural pressures on women to conform to an idealised body shape are more powerful and more wide spread than those on men. Psychologists have suggested that the media can affect women’s body esteem by becoming a reference point against which unfavourable body shape comparisons are made (Grogan 1999). These visions are then propagated through popular culture via television reality make over shows of re shaping the body, â€Å" if films of body transformation provide the vision that inspires women to re- make their bodies, the cosmetic and â€Å"aesthetic medicine† industry sell them the equipment† (Fox-Kales, 2011, p. 74. ) Women are objectified by an unrealistic expectation of beauty, put forward by models and actresses who do not reflect the average appearance of women in society. Print advertising, in particular, provides a not only unrealistic, but unhealthy ideal of what it means to be physically attractive. By these false images being presented, the media has created an ideology of attractiveness. Images have powerful effects on their readers, serving to maintain a ‘cult of femininity’ and supplying definitions of what it means to ‘be a woman’. Marjorie Ferguson (1985) investigated women’s magazines from a sociological perspective. She argued that women’s magazines contribute to the wider cultural process, which helps to shape a woman’s view of herself, and societies views of her. The media is littered with mages of females who fulfill these unrealistic standards, making it seem as if it is normal for women to live up to this ideal. Dittmar and Howard (2004) made this statement regarding the prevalence of unrealistic media images: Ultra-thin models are so prominent that exposure to them becomes unavoidable and ‘chronic’, constantly reinforcing a discrepancy for most women and girls between their actual size and the ideal body (p. 478). Research has repeatedly shown that constant exposure to thin models and actresses fosters body image concerns and disordered eating in many females. Eating Disorders are a direct result from the medias influence to look ‘thin’. Eating disorders theorists and feminist scholars have long indicated fashion magazines, movies, television, and advertising for their advocacy of disordered eating (Levine & Smolak, 1998). Media images of women make it difficult for individuals to hold an internalized ideal body that is realistic and attainable. With exposure to repeated images of ultra thin women, an individual’s internalized ideal body often becomes much thinner. This increases the gap between what a person feels their physical appearance is, and what it should be. Researchers have found that women who have an internalized ideal body that closely resembles the socially represented ideal body are at a particularly high risk to develop body image disturbance and disordered eating patterns (Sands & Wardle, 2003). Naomi Wolf argues that our culture disempowers women by holding them prisoner to an unattainable beauty ideal (Wolf, 1990). The epidemic proportions of drive for thinness, body dissatisfaction, and unsafe weight control methods among women have led theorists to posit the existence of mechanisms that are capable of reaching a large number of women (Levine & Smolak, 1998). Today’s expectations reveal that looks matter more than personality and intelligence as seen on various dating shows. It is universally agreed upon that people on these shows usually pick the best looking counterpart out of the group of contestants. Both men and women are concerned with appearance than personality on these types of programs. This phenomenon is transferred into the job market, where people are now more prone to hire the more attractive candidate. Research has found that more attractive workers even receive higher compensation than unattractive counterparts even where they perform the same work and have similar levels of work experience. The media targets young women drilling thinness and having no flaws as the height of being beautiful. Now, with the common use of plastic surgery you can change your overall appearance. Plastic surgery has become a more than 8 billion a year industry† (Hess – Biber, 2005:96). Women feel they need to have the perfect nose, and cheek bones to fit in to the media’s criteria, in order to appear more attractive to the opposite sex. Therefore, it is evident that the media has played a significant role in ‘shaping women’s bodies’ to suit ‘societies expectations’ by showcasing the recurring idea to be ‘thin’. These ideas are brought upon through various television shows and magazines, which further stimulate eating disorders.

How to Organize and Manage Classroom Learning Centers

Classroom Learning centers are a great way for students to work together to accomplish a given task. They provide the opportunity for children to practice hands-on skills with or with out social interaction depending upon the teachers task. Here you will learn tips on how to organize and store center content, along with a few suggestions on how to manage classroom centers. Organize and Store Contents Every teacher knows that an organized classroom is a happy classroom. To ensure your learning centers are neat and tidy, and ready for the next student, it is essential to keep learning center contents organized. Here are a variety of ways to organize and store classroom centers for easy access. Place task in small plastic bins and label with the word and picture.Place task in gallon size Ziploc bags, label and place in, or clip to, an accompanying file folder.A great way to keep your Ziploc bag sturdy is to place a piece of cardboard (cut the front off of a cereal box) and place it in the bag. Then on the blank side of the cardboard print the topic of the learning center and the directions. Laminate for easy reuse.Place little components of the learning center into small size Ziploc baggies and label.Place center task in shoe box labeled with the number that corresponds to the Common Core Standard.Take a coffee container and place task inside the container.

Reading centers are in pink baskets, math centers are in blue, etc.Buy a colored drawer organizing rolling cart and place center task i nside.Create a bulletin board, adhere library pockets to the board and place the learning center task inside. Post directions on the bulletin board. Lakeshore Learning has storage bins in a variety of sizes and colors that are great for learning centers. Manage Learning Centers Learning centers can be a lot of fun but they also can get quiet chaotic. Here are a few suggestions on how to set up and manage them. First, you must plan the structure of the learning center, are students going to work alone or with a partner? Each learning center can be unique, so if you choose to give students the option to work alone or with a partner for the math center, you do not have to give them an option for the reading center.Next, you must prepare the contents of each learning center. Choose the way you plan on storing and keeping the center organized from the list above.Set up the classroom so that children are visible at all centers. Make sure you create centers around the perimeter of the classroom so children wont bump into one another or get distracted.Place centers that are alike near each other, and make sure if the center is going to use materials that are messy, that is it placed on a hard surface, not a carpet.Introduce how each center works, and model how they must complete each task.Discuss, and model the behavior that is expected of students at each center and hold students responsible for their actions.Use a bell, timer, or hand gesture when it is time to switching centers. Here are more ideas on how to prepare, set up and present learning centers.

The Heinkel He 111 or the Luftwaffe Bomber

With its defeat in World War I, the leaders of Germany signed the Treaty of Versailles which formally ended the conflict. Though a far-reaching agreement, one section of the treaty specifically forbade Germany from constructing and operating an air force. Due to this restriction, when Germany commenced rearmament in the early 1930s, aircraft development occurred in secrecy or proceeded under the guise of civilian use. Around this time, Ernst Heinkel commenced an initiative to design and build a high-speed passenger plane. To design this aircraft, he hired Siegfried and Walter Gà ¼nter. The result of the Gà ¼nters efforts was the Heinkel He 70 Blitz which began production in 1932. A successful aircraft, the He 70 featured an elliptical inverted gull wing and a BMW VI engine. Impressed with the He 70, the Luftfahrtkommissariat, which sought a new transport aircraft that could be converted to a bomber in wartime, contacted Heinkel. Responding to this inquiry, Heinkel began work to enlarge the aircraft to meet the requested specifications and to compete with new twin-engine aircraft such as the Dornier Do 17. Preserving the key features of the He 70, including the wing shape and BMW engines, the new design became known as the Doppel-Blitz (Double Blitz). Work on the prototype pushed forward and it first took to the skies on February 24, 1935, with Gerhard Nitschke at the controls. Competing with the Junkers Ju 86, the new Heinkel He 111 compared favorably and a government contract was issued. Design Variants Early variants of the He 111 utilized a traditional stepped cockpit with separate windscreens for the pilot and copilot. Military variants of the aircraft, which began production in 1936, saw the inclusion of dorsal and ventral gun positions, a bomb bay for 1,500 lbs. of bombs, and a longer fuselage. The addition of this equipment adversely affected the He 111s performance as the BMW VI engines did not produce sufficient power to offset the additional weight. As a result, the He 111B was developed in the summer of 1936. This upgrade saw more powerful DB 600C engines with variable pitch airscrews installed as well as additions to the aircrafts defensive armament. Pleased with the improved performance, the Luftwaffe ordered 300 He 111Bs and deliveries commenced in January 1937. Subsequent improvements produced the D-, E-, and F-variants. One of the most notable changes during this period was the elimination of the elliptical wing in favor of a more-easily produced one featuring straight leading and trailing edges. The He 111J variant saw the aircraft tested as a torpedo bomber for the Kriegsmarine though the concept was later dropped. The most visible change to the type came in early 1938 with the introduction of the He 111P. This saw the entire forward part of the aircraft altered as the stepped cockpit was removed in favor of a bullet-shaped, glazed nose. In addition, improvements were made to the power plants, armament, and other equipment. In 1939, the H-variant entered production. The most widely produced of any He 111 model, the H-variant began entering service on the eve of World War II. Possessing a heavier bomb load and greater defensive armament than its predecessors, the He 111H also included enhanced armor and more powerful engines. The H-variant remained in production into 1944 as the Luftwaffes follow-on bomber projects, such as the He 177 and Bomber B, failed to yield an acceptable or reliable design. In 1941, a final, mutated variant of the He 111 commenced testing. The He 111Z Zwilling saw the merging of two He 111s into one large, twin-fuselage aircraft powered by five engines. Intended as a glider tug and transport, the He 111Z was produced in limited numbers. Operational History In February 1937, a group of four He 111Bs arrived in Spain for service in the German Condor Legion. Ostensibly a German volunteer unit supporting Francisco Francos Nationalist forces, it served as a training ground for Luftwaffe pilots and for evaluating new aircraft. Making their combat debut on March 9, the He 111s attacked Republican airfields during the Battle of Guadalajara. Proving more effective than the Ju 86 and the Do 17, the type soon appeared in larger numbers over Spain. Experience with the He 111 in this conflict allowed designers at Heinkel to further refine and improve the aircraft. With the beginning of World War II on September 1, 1939, He 111s formed the backbone of the Luftwaffes bombing assault on Poland. Though performing well, the campaign against the Poles revealed that the aircrafts defensive armament required enhancement. In the early months of 1940, He 111s conducted raids against British shipping and naval targets in the North Sea before supporting the invasions of Denmark and Norway. On May 10, Luftwaffe He 111s aided ground forces as they opened the campaign in the Low Countries and France. Taking part in the Rotterdam Blitz four days later, the type continued to strike both strategic and tactical targets as the Allies retreated. At the end of the month, He 111s mounted raids against the British as they conducted the Dunkirk Evacuation. With the fall of France, the Luftwaffe began preparing for the Battle of Britain. Concentrating along the English Channel, He 111 units were joined by those flying the Do 17 and Junkers Ju 88. Commencing in July, the assault on Britain saw the He 111 encounter fierce resistance from Royal Air Force Hawker Hurricanes and Supermarine Spitfires. The early phases of the battle showed a need for the bomber to have a fighter escort and revealed a vulnerability to head-on attacks due to the He 111s glazed nose. In addition, repeated engagements with British fighters showed that the defensive armament was still inadequate. In September, the Luftwaffe switched to targeting British cities. Though not designed as a strategic bomber, the He 111 proved capable in this role. Fitted with Knickebein and other electronic aids, the type was able to bomb blind and maintained pressure on the British through the winter and spring of 1941. Elsewhere, the He 111 saw action during the campaigns in the Balkans and the invasion of Crete. Other units were sent to North Africa to support the operations of the Italians and the German Afrika Korps. With the German invasion of the Soviet Union in June 1941, He 111 units on the Eastern Front were initially asked to provide tactical support for the Wehrmacht. This expanded to striking the Soviet rail network and then to strategic bombing. Later Operations Though offensive action formed the core of the He 111s role on the Eastern Front, it also was pressed into duty on several occasions as a transport. It earned distinction in this role during by evacuating wounded from the Demyansk Pocket and later in re-supplying German forces during the Battle of Stalingrad. By the spring of 1943, overall He 111 operational numbers began to decline as other types, such as the Ju 88, assumed more of the load. In addition, increasing Allied air superiority hampered offensive bombing operations. During the wars later years, the He 111 continued to mount raids against Soviet shipping in the Black Sea with the assistance of FuG 200 Hohentwiel anti-shipping radar. In the west, He 111s were tasked with delivering V-1 flying bombs to Britain in late 1944. With the Axis position collapsing late in the war, He 111s supported numerous evacuations as German forces withdrew. The He 111s final missions of the war came as German forces attempted to halt the Soviet drive on Berlin in 1945. With the surrender of Germany in May, the He 111s service life with the Luftwaffe came to an end. The type continued to be used by Spain until 1958. Additional license-built aircraft, constructed in Spain as the CASA 2.111, remained in service until 1973.

Essay On Different Styles Of Writing To Different Audience

Different Styles of Writing and Appealing to Different Audiences The years a child spends in elementary are crucial because their teachers will essentially lay down the foundation for learning, as well as stimulate an interest in growing knowledge. The various subjects students are taught include math, science, English language arts, and history. However, within those subjects, there are skills that students need to learn and master so they can be efficient learners. Each subject contains its challenges, but with great teachers, students will be able to develop the adequate skills to make them successful in subjects they find challenging. I will be focusing on why students struggle with writing and the methods they are taught in order to†¦show more content†¦With that being said, it is very difficult for teachers to go into the field and teach children a skill that they lack proper practice in themselves. How and Who to Write To Approach to Writing In addition, the way in which students approach writing essays will determine how great of an essay they write. Students who are given the sufficient information, time, and tools to prepare them to compose a well-written piece of work, are more often confident with their writing skills. For example, providing students with a rubric is a way for students to have an idea of how they will approach their essay. The rubric approach is has evolved from spelling, punctuation, and grammar to focusing on the aspects of writing such as voice, purpose, and organization (Bridge, Compton-Hall Cantrell, 1997). Understanding that writing requires plenty of practice and development is key, but also knowing that as the students progress through elementary so will their writing. Typically children are taught writing through a process that usually contains five steps: prewriting, drafting, revising, editing, and publishing.

This is because the throttle which is situated in the air intake duct of the petrol engine. For the petrol engine, the combustion takes place in the whole cylinder, so the air-fuel ratio should be maintained to make sure the combustion to take place rapidly enough all the time. The throttle will adjust the air-fuel ratio. For the diesel engine, the combustion takes place around individual droplets of the fuel spray, therefore the output is related to the amount of fuel injected, and the air flow is not controlled. Fig 2 shows that the efficiency increases with the power for both engines, however the diesel engine reaches higher efficiency than the petrol engine. This is because, for the diesel engine, the input of the fuel is in the form of fuel spray. The compression of the fuel and air is avoided. This will make the maximum cylinder volume to minimum larger, and leads to higher efficiency. So, the petrol engine should be used in light vehicles because it is lighter than the diesel engine and it can reach higher power than the diesel engine which produces higher speed of the cars.

This is because the throttle which is situated in the air intake duct of the petrol engine. For the petrol engine, the combustion takes place in the whole cylinder, so the air-fuel ratio should be maintained to make sure the combustion to take place rapidly enough all the time. The throttle will adjust the air-fuel ratio. For the diesel engine, the combustion takes place around individual droplets of the fuel spray, therefore the output is related to the amount of fuel injected, and the air flow is not controlled. Fig 2 shows that the efficiency increases with the power for both engines, however the diesel engine reaches higher efficiency than the petrol engine. This is because, for the diesel engine, the input of the fuel is in the form of fuel spray. The compression of the fuel and air is avoided. This will make the maximum cylinder volume to minimum larger, and leads to higher efficiency. So, the petrol engine should be used in light vehicles because it is lighter than the diesel engine and it can reach higher power than the diesel engine which produces higher speed of the cars. And, the diesel engine should be used for the heavy vehicles, since it has higher efficiency. The heavy cars need to do more work, so the efficiency is more important to them.

Model 2 Google search: Input: 1. Search words 2. Location 3. In case, if signed in Gmail identification 4. Last searches in same session. 5. IP address Processing: Google Search can be divided into two parts. 1. Storing the details about pages in web 2. Retrieving relevant page on search Storing the details about web: In Google, the web crawling (downloading of web pages) is done by several distributed crawlers. There is a URLserver that sends lists of URLs to be fetched to the crawlers. The web pages that are fetched are then sent to the storeserver. The storeserver then compresses and stores the web pages into a repository. Every web page has an associated ID number called a docID which is assigned whenever a new URL is parsed out of a web page. The indexing function is performed by the indexer and the sorter. The indexer performs a number of functions. It reads the repository, uncompresses the documents, and parses them. Each document is converted into a set of word occurrences called hits. The hits record the word, position in document, an approximation of font size, and capitalization. The indexer distributes these hits into a set of barrels, creating a partially sorted forward index. The indexer performs another important function. It parses out all the links in every web page and stores important information about them in an anchors file. This file contains enough information to determine where each link points from and to, and the text of the link. The URLresolver reads the anchors file and converts relative URLs into absolute URLs and in turn into docIDs. It puts the anchor text into the forward ndex, associated with the docID that the anchor points to. It also generates a database of links which are pairs of docIDs. The links database is used to compute PageRanks for all the documents. The sorter takes the barrels, which are sorted by docID , and resorts them by wordID to generate the inverted index. This is done in place so that little temporary space is needed for this operation. The sorter also produces a list of wordIDs and offsets into the inverted index. A program called DumpLexicon takes this list together with the lexicon produced by the indexer and generates a new lexicon to be used by the searcher. The searcher is run by a web server and uses the lexicon built by DumpLexicon together with the inverted index and the PageRanks to answer queries. Retrieving relevant page on search: User is aware of this part, as the explicit input of search criteria is provided. But along with criteria, other inputs such as location, search pattern and many such criteria are going. For example, If we search same word say † Uganda† from Google, different people get different input. Output: The zillions of pages related to the current search criteria is shown as anchor. Control and monitoring: Users are allowed to enter any input in the text box. But based on their input, Advertisements and search inputs are considered. Storage for Future: Based on the sites visited, search pattern is determined. This is used to display the list of sites next time. Based on the popular search inputs stored, a drop down box is displayed to aid users to complete the search criteria. Also, the sites are ranked to display in order. Model 3 Restaurant 1. Input Transaction processing systems are information systems which collect, store, modifies and retrieves the daily transactions of an organization. TPSs are all to do with business, money and most importantly securing and recording the daily transactions of a company. Four important characteristics of a TPS are: * Rapid Response * Reliability * Inflexibility * Controlled Processing * Batch Processing * Real – Time Processing * Transaction Process Monitors * Data Validation * Manual Transaction Systems A transaction is any event that passes the ACID test in which data is generated or modified before storage in an information system. Transactions Processing Qualifiers In order to qualify as a TPS, transactions made by the system must pass the ACID test. The ACID tests refers to the following four prerequisites: Atomicity Atomicity means that a transaction is either completed in full or not at all. For example, if funds are transferred from one account to another, this only counts as a bone fide transaction if both the withdrawal and deposit take place. If one account is debited and the other is not credited, it does not qualify as a transaction. TPS systems ensure that transactions take place in their entirety. Consistency TPS systems exist within a set of operating rules (or integrity constraints). If an integrity constraint states that all transactions in a database must have a positive value, any transaction with a negative value would be refused. Isolation Transactions must appear to take place in isolation. For example, when a fund transfer is made between two accounts the debiting of one and the crediting of another must appear to take place simultaneously. The funds cannot be credited to an account before they are debited from another. Durability Once transactions are completed they cannot be undone. To ensure that this is the case even if the TPS suffers failure, a log will be created to document all completed transactions. These four conditions ensure that TPS systems carry out their transactions in a methodical, standardised and reliable manner. 2. Process For a restaurant, the process architecture and design is as follows: The physical design of a TPS system for a restaurant is as follows: Output: Entry: 1. The Member hands over the membership card. 2. The receptionist scans the card and generates an order slip and the table # is generated. Ordering: 3. The waitress takes the order slip and inputs it into the order entry process system and feeds the order details into the table records. 4. The table processing system interacts with the other processing systems for Bar order, Kitchen orders Exiting: 5. The table records flow to the billing process system. 6. The Billing process system generates and processes the bill receipt. 7. After the customer’s signature, an order slip is generated and the receptionist scans the bill into the billing process system. 8. The Billing processing system processes it to the Monthly billing system.
