Analysis Of The Book Crossing Borders International...

Presentation Paper Throughout this course I learned a lot about globalization and the world around me. Today’s world is much closer than it has been in the past. Countries rely on one another and seek security and safety from one another as well. Often times if something bad happens to one country neighboring countries and countries associated with them can feel the harsh effects. Being that the world is so close to together one can see similarities throughout the world. Globalization has brought social, cultural, political, and economic similarities between countries. Many countries have geographic borders, political borders, economic borders, social borders, and cultural borders have been threatened and overcome, because of the rise of†¦show more content†¦They fear they will lose their roots and backgrounds that define who they are. With these new changes and challenges arising people want to stay true to who they are and will do anything to protect it. This is wh ere problems may occur. With so much integration and migration with people fleeing their home countries to feel safe in another often times religious groups, ethnic, and state failure can put a strain on relationships. Learning new ways of living, new religions, languages, and meeting new people can cause individual cultural heritage to vanish. Overcoming these differences and accepting others along with keeping one’s own identity can be a very tough thing to succeed at. Religion is a big factor that can threaten people’s identities. Religions clash and problems can arise that can cause huge problems for governments and their people. Since the beginning of time religion has caused numerous conflicts between different religious groups. Some examples are the views of Confucianism, early Christianity, Divisions in India, and Christianity in the Crusades. Religious fights can be a major setback for globalization. It shows some of the negative effects of globalization, bein g that often times religious groups can’t get along with one another, because of their differing views and past experiences. A major religious debate that continues to go on today is the struggle between the

Summary of on the Meaning of Plumbing and Poverty Essay

Bryce Gray English 1103 Summary amp; Strong Response On The Meaning Of Plumbing and Poverty Summary In her essay â€Å"On The Meaning Of Plumbing and Poverty,† Journalist Melanie Scheller examines the cultural identity of the rural poor. The author brings the readers attention to her call to action about poverty in America while using facts and personal background. While caring for a woman in a psychiatric ward, Scheller witnesses the woman’s obsession for flushing the toilets in her unit. This memory creates an opportunity for her to write an essay about growing up in rural North Carolina. In the 1960’s the author was growing up with her mother and five other siblings, moving from place to place in search of a home where the†¦show more content†¦She is extremely effective in supporting her main idea by supplying the reader with descriptive detail on how she grew up and how certain things took place in rural North Carolina during the 1960’s. These details grasp the reader’s attention immed iately by implementing such detail that while reading the words on each page, a visual picture can be envisioned by the reader. Many feelings are provoked in a child who lives without basic needs met. I believe that this essay brings many new perspectives into view because it describes a basic element needed in an individual’s life that is vastly overlooked and often taken for granted. My point of view was altered when Scheller described her living quarters with her other siblings and made me appreciate those little things in life, such as my bedroom as well as a shower and toilet that I can call my own. Bringing awareness to poverty is important, and this essay has done a fine job in doing so. Not only does it touch on poverty but also on passing judgment on individuals when we really don’t know what they could be going through. When Scheller describes how the children at school react to others who don’t have much, it causes me to think about how blessed the ma jority of the population in America really is and also provokes the question, what can we do to help those in need of what we like to call â€Å"basic necessities†?

Clean Air Act free essay sample

I will also discuss my feelings on whether this law has been beneficial and also provide information to support my answer. Clean Air Act The Clean Air Act of 1970 is a federal law created to control emissions in the air from immobile and transportable sources. This law gives the Environmental Protection Agency permission to launch four main governing programs: The National Ambient Air Quality Standards, also known as NAAQS, in order to safeguard community well-being and safety as well as control the release of harmful toxins which pollute the air. State Implementation Plans, also known as SIPs; National Emissions Standards for Hazardous Air Pollutants, also known as NESHAPs; and New Source Performance Standards, also known as NSPS. The Environmental Protection Agency was created December 2, 1970 in order to carry out the requirements of the Clean Air Act of 1970 (EPA, 2013). There were provisions made to the Clean Air Act in 1977 and in 1990. President Jimmy Carter signed into law H. We will write a custom essay sample on Clean Air Act or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page R. 6161, also known as the Clean Air Amendment of 1977, on August 8, 1977. This amendment had three main provisions which proved the legal support for the EPA to carry out a solid and reliable program for meeting and upholding the standards for air quality for protecting the health of our overall population. This provision requires the auto business to follow a strict schedule for reducing emissions by making cars that help with keeping the air cleaner and help to improve the effectiveness of gasoline. This provision is going to help in protecting the deprivation of our national parks, forests, and monuments caused by air pollution (Peters, G. 2013). Another provision to the Clean Air Act was in 1990, known as the Clean Air Amendment of 1990. President Bush introduced the amendment for the Clean Air Act in September of 1989. The amendment passed Senate in April of 1990 and passed House in May of 1990 and was then signed by President Bush on November 15, 1990. This amendment is a federal law that covers the entire country but makes each state responsible for following this amendment. The EPA provides boundaries for how much contaminant are allowed in the atmosphere within the U. S. Each state is responsible for developing state implementation plans (SIPs) that clarifies how each state is supposed to follow the law for the Clean Air Act and can only be approved by the EPA. Some of the provisions of this amendment are: to reduce interstate air pollution; international air pollution; and permits for businesses that tend to release air pollutants. The EPA enforces the 1990 Clean Air Act and also sets deadlines for businesses to reduce the pollution in the air. The amendment will allow for the clean-up of fuels, cars will come equipped with systems under the hood and under the dashboard that provide warning lights to see if the devices for the control of pollution are working the way they are supposed to; automobile maintenance and vehicle maintenance will be enforced; a reduction in soot and dust from diesel vehicles; regulation of trains, lawnmowers, and equipment for construction; in order to reduce smog, and cities are asked to encourage people to car pool or use HOV (high occupancy vehicle ) lanes (Policy Almanac, 2002). The Clean Air Act of 1970 along with the amendments in 1977 and 1990 were initiated to help in the reduction of air pollution in the United States. This law was passed so that the Environmental Protection Agency could set standards for the protection of the depletion of the ozone and emissions of pollutants which are air-borne (American Business, 2010). The Clean Air Act is an extremely significant law that was created for our population’s health and for the protection of the environment. The benefits of this act are far more important than what it cost to accomplish them. 05,000 premature births were prevented, 843,000 asthma attacks were prevented, and 18 million respiratory sicknesses among children were prevented within the first 20 years of the Clean Air Act. The amendment to this act in 1990 allowed for a reduction in 160,000 premature deaths in 2010 and predicts that there will be an estimate of 230,000 premature deaths prevented by 2020. The EPA also estimates 17 million works days lost will be prevented by 2020 which will help businesses and the economy. The U. S. s the largest manufacturer and consumer for technology in the protection of the environment with an estimated market of $782 billion. The equipment for controlling air pollution brought in income of around $18 billion to include exported goods of around $3 billion. Exports and trade for technology for the environment brought in a residual of approximately $20 billion. The U. S. has approximately 119,000 businesses that participate in using environmental equipment which helps to bring in revenue of $300 billion, providing approximately 1. million jobs, and around $43. 8 billion in export goods. The release of pollutants in the air dropped by 63% from 1970-2009. The reduction of air pollution has for operating, capital, and expenditures was totaled to $26. 6 billion which is estimated to be less than a percent of their total residual. The EPA strongly enforc es this law and administrative penalties of up to $200,000, field citations of approximately $5,000; and civil or criminal penalties with anything from misdemeanors to felonies (EPA, 2013). After reading about the Clean Air Act and learning about the different issues with the environment and what we can do to help protect our environment, I feel that this act is helping the environment but it certainly is not something that can be easily fixed. Working to clean our air up is going to take time and effort from everyone. I feel that if each person in the U. S. would do their part, we can continue to improve the quality of air. The Clean Air Act has proven to be a good thing by having cleaner air and the health of our population has shown improvement. There has been a reduction of toxic lead emissions by 98%; reduction of sulfur dioxide emissions by 35% with double of the GDP; and a reduction of carbon monoxide emissions by 32% with an increase of drivers by 127% (Clean Air Trust, 1999).

Oh yeah Essay Example For Students

Oh yeah Essay David OcampoHonor English IV2/21/02The Use of Sound in Shakespeares Sonnetsby Barbara Herrnstein Smith This article argues that Shakespeares use of the meter, or general structure of sounds, in his poetry is as significant to his style as his metaphors, figurative language, and images. Shakespeare used developed techniques, however, he executed them more effectively. Shakespeare was able to execute the iambic to sound natural, similar to natural speech, rather than artificial and mechanical, as it usually sounds. Shakespeare was also able to manipulate words to create musical sounds with combinations and repetitions of vowel and consonant sounds. The article states that Shakespeare was able to master the musical potentialities of the language. This was perfectly executed through his use of complex distributions of phonetic elements, and operating with the internal rhythm, producing the true harmony of well-tuned sounds. Also, Shakespeare was able to manipulate the iambic meter to sound similar to natural speech. Traditional iambic meter poetry has a tendency to sound artificial and mechanical. However, Shakespeare was skillful enough to dominate the techniques of English poetry and, thus, was able to avoid the distorted natural emphasis of speech and evaded the mechanical regularity of thumping in such poetry.

A Farewell To Arms Essays (607 words) - Ernest Hemingway

A Farewell to Arms Critics usually describe Hemingway's style as simple, spare, and journalistic. These are all good words; they all apply. Perhaps because of his training as a newspaperman, Hemingway is a master of the declarative, subject-verb-object sentence. His writing has been likened to a boxer's punches--combinations of lefts and rights coming at us without pause. Take the following passage: We were all cooked. The thing was not to recognize it. The last country to realize they were cooked would win the war. We had another drink. Was I on somebody's staff? No. He was. It was all balls. The style gains power because it is so full of sensory detail. There was an inn in the trees at the Bains de l'Allaiz where the woodcutters stopped to drink, and we sat inside warmed by the stove and drank hot red wine with spices and lemon in it. They called it gluhwein and it was a good thing to warm you and to celebrate with. The inn was dark and smoky inside and afterward when you went out the cold air came sharply into your lungs and numbed the edge of your nose as you inhaled. The simplicity and the sensory richness flow directly from Hemingway's and his characters'--beliefs. The punchy, vivid language has the immediacy of a news bulletin: these are facts, Hemingway is telling us, and they can't be ignored. And just as Frederic Henry comes to distrust abstractions like "patriotism," so does Hemingway distrust them. Instead he seeks the concrete, the tangible: "hot red wine with spices, cold air that numbs your nose." A simple "good" becomes higher praise than another writer's string of decorative adjectives. Though Hemingway is best known for the tough simplicity of style seen in the first passage cited above, if we take a close look at A Farewell to Arms, we will often find another Hemingway at work--a writer who is aiming for certain complex effects, who is experimenting with language, and who is often self-consciously manipulating words. Some sentences are clause-filled and eighty or more words long. Take for example the description in Chapter 1 that begins, "There were mists over the river and clouds on the mountain"; it paints an entire dreary wartime autumn and foreshadows the deaths not only of many of the soldiers but of Catherine. Hemingway's style changes, too, when it reflects his characters' changing states of mind. Writing from Frederic Henry's point of view, he sometimes uses a modified stream-of-consciousness technique, a method for spilling out on paper the inner thoughts of a character. Usually Henry's thoughts are choppy, staccato, but when he becomes drunk the language does too, as in the passage in Chapter 3: I had gone to no such place but to the smoke of cafes and nights when the room whirled and you needed to look at the wall to make it stop, nights in bed, drunk, when you knew that that was all there was, and the strange excitement of waking and not knowing who it was with you, and the world all unreal in the dark and so exciting that you must resume again unknowing and not caring in the night, sure that this was all and all and all and not caring. The rhythm, the repetition, have us reeling with Henry. Thus, Hemingway's prose is in fact an instrument finely tuned to reflect his characters and their world. As we read A Farewell to Arms, we must try to underezd the thoughts and feelings Hemingway seeks to inspire in us by the way he uses language.

Essay Sample on the History of Indian Trade Diverse Sources

Essay Sample on the History of Indian Trade Diverse Sources India, as a country with immense resources available through it’s length and breadth, has enabled it to gain a foothold in the major and the not so major economies of the world. The objective of this brief paper is to highlight the immense and diverse sources of Indian trade with all the major regions and countries of the globe spanning right from the Americas, the UK and other European Union countries to the Middle Eastern nations to China as well as to the South East Asian tiger economies. During the time India gained Independence from the Britishers in 1947, the economy was entirely geared to only trade and there was hardly any manufacturing facilities at all to provide for the colossal Indian population. Hence, it has now taken all of the 60 years of toil and industry to create manufacturing capacities across the board to manufacture everything from satellites to hairpins. Needless to say, even the infrastructure has had to be created though a lot yet needs to be done in terms of airports, shipping ports, roads, etc.. The government has now rightly been focusing on the same to enable broadbasing the development to move the economy from an underdeveloped status to being a developed nation. India is now already a $1 trillion economy. India has given to the world Darjeeling tea, Indian khadi cotton, Bombay Duck, Kashmiri carpets, Indian spices and dry fruit and the varied cuisines right from the mountains of Kashmir in the north to Gods own country of Kerala in the south of India. London itself has approx. 7000 restaurants serving the various Indian exotic cuisines. Chicken curry is now almost considered a part of British cuisine. Any major financial or tourist destination across the globe has to, perforce, have some Indian cuisine available. Also, as economic levels have improved in the urban and semi-urban areas, there has also been increased penetration of literacy leading to higher consumption patterns for all kinds of goods across all sections of the society. This has led to more awareness of the availability of goods from all parts of the world and this has resulted in more trade with other countries. This has resulted in surpluses being generated in some goods whereas other goods are being imported to satisfy the needs of the population. Overall Indian trade has benefited and so has the world. At the end of the day, it is all about maximizing use of one’s resources. This is a sample Business essay written from scratch by one of our academic writers.

English - Research Paper Example However, once fans found out that Tim Burton would be in charge of the project, many fears and doubts were alleviated. Indeed, nobody left the theater feeling disappointed. Janet Maslin, a writer with The New York Times, states that, â€Å"[...] An ornate visual fantasy of Mr. Burton’s can be expected to make its own rules, and Sleepy Hollow does that with macabre gusto.† Maslin continues her article with much praise for the â€Å"grimly voluptuous† Sleepy Hollow. Burton made his name in the film industry by never holding back when trying to display or explain something. If the scene called for horror, he would deliver horror, and then some. While the fans of Burton are used to his macabre style, many were still shocked, though pleasingly so, with how far he took the graphics in Sleepy Hollow. As Tim Burton has a very distinctive style with his filming, people expected quite a bit out of Sleepy Hollow. While most directors either get away or not with how they film something, a specific outcome is expected from Tim Burton. Kamal Larsuel-Ulbricht, for one, was not disappointed. In her review (1999), she expresses a certain fondness for the result of Sleepy Hollow, saying, â€Å"This was not Disney’s ‘Sleepy Hollow’. [Tim Burton] is sometimes a bit too weird for those who don’t quite understand his style [but for those who do], people can appreciate this take on The Legend of Sleepy Hollow.† So it would seem, those that can really take away something from the film would be those that are already familiar with Tim Burton’s unique style of directing. Justin Felix (1999) considers Sleepy Hollow to count â€Å"among [Tim Burton’s] better movies,† further stating that, â€Å"With the recent disappointments in theatrically released horror movies, we needed a film like this.† Felix takes his review a little bit further by commenting on the aspects that

Application Demonstration - Essay Example A client logs in from the client application and upon proper authentication with the server, the client application’s IP address is stored by the server and the client’s status is made to ‘Online’. As such, at any given time, the server maintains two basic things, the list of contacts of any client (who are clients themselves), the clients who are online and the IP addresses of the online clients. At the client end, the message is decrypted using predefined logic and the online and offline contacts are displayed to the customer in predefined separate formats (the online contacts are colored while the offline ones are grayed). The server receives the message and determines the contact. It checks whether the client contact is online, in which case, a socket with the client contact is opened. Otherwise, the server responds to the client with a ‘Contact offline at the moment, send offline message’ message. In case a contact is offline, the server stores the message in its database. Whenever the client contact comes online, the server initially queries the database to determine if there were any offline messages. If there were any such messages, the server relays the offline messages to the client, wherein they are displayed in a separate dialog with the messages being grouped according to the client who sent the

Comparative politics and Governance Essay Example | Topics and Well Written Essays - 1000 words

Comparative politics and Governance - Essay Example France is taken to be the birthplace of liberal democracy in the modern era, sharing leadership culturally in the development of democratic society internationally with Britain and the USA. The ideals of democracy can be found in literature and transported to any location, but their implementation as a system of government is most strong in the USA and France today. Britain still has the House of Lords and Monarchy which illustrate the feudal patterns of society which liberal democracy replaced, and Spain also has a Constitutional Monarchy and King. The patterns of democratic liberalism found in the USA and France are used as a basis for development of similar systems in nation-states around the world in the process of modernization that relates to democratization internationally. Jurgen Habermas (1994) discusses the process of democratization as it aligns with modernization in his work, â€Å"Three Normative Models of Democracy,† relating the different stages a nation may ent er into as the people emerge from feudal power relations. (Habermas, 1994) Following this theory, liberal democratic structures will increase in a society as the culture develops economically and through education, adopting scientific standards, and becoming globalized. This theory would suggest that the world’s most advanced economies, such as the U.S., France, and Spain, would be also the most free historically, or have the highest advocacy for democratic institutions. Yet, China has the second largest economy globally, and it is often found to be lacking in liberal democratic openness on these standards. Similarly, Russia replaced the Soviet regime with a technically democratic system, and still has a strong economy today, yet international watchdogs regularly report human rights abuses and undemocratic processes in the country. This leads to the conclusion that there is not a direct relation between the size or advancement of an economy and liberal democracy as a politica l system inherently, as seen particularly in Russia and China today, but also in historical examples from around the world. Nevertheless, the relationship between modernization and democratization does proceed together in many nations historically, as Barber and other show in their studies on political sociology. (Barber, 2003) 2: The separation of executive and legislature is a fundamental requirement of democratic government’. Discuss. The separation of the legislature and executive is not the fundamental characteristic of democratic government, because the Parliamentary system of government links the Prime Minister directly to the ruling party and its control of the majority of legislators. What is more important than the relationship of separation of powers and indicative of a liberal democracy historically is the use of a constitution in the establishment of the system of government itself. Habermas, in such works as â€Å"On the Internal Relation between the Rule of La w and Democracy† (1995), describes the existence of a constitution as a foundation document in a system of government as characteristic and a predictor of democratic liberalism. (Habermas, 1995) Yet, France, Spain, US, Russia and Nigeria all have constitutions and make claims to political liberalism, but in practice display

Types And Uses Of Coupling Devices Engineering Essay

Types And Uses Of Coupling Devices Engineering Essay A coupling is a device used to connect two shafts together at their ends for the purpose of transmitting power.In machinery, a device for providing a connection, readily broken and restored, between two adjacent rotating shafts.A coupling may provide either a rigid or a flexible connection; the flexibility may permit misalignment of the connected shafts or provide a torsionally flexible (yielding) connection, mitigating effects of shock Couplings do not normally allow disconnection of shafts during operation, though there do exist torque limiting couplings which can slip or disconnect when some torque limit is exceeded. A common type of rigid coupling consists of two mating radial flanges (disks) that are attached by key-driven hubs to the ends of the shafts and bolted together through the flanges. Alignment of the shafts is usually achieved by means of a short cylindrical projection (rabbet joint) on the face of one flange that fits snugly into a circular recess on the face of the other flange. The chain coupling consists of two hardened-steel sprockets, one on each shaft, with a nylon or metal roller chain wrapped around the closely aligned sprockets and connected at the ends. Clearances between the sprocket teeth and the chain allow for a small amount of shaft misalignment. For connecting shafts whose axes intersect but are inclined to one another at a larger angle than a flexible coupling can accommodate, universal joints are used. The most common of these is the Hooke, or Cardan, joint, which consists of two yokes attached to the shaft ends and a cross-shaped connecting member. Uses Shaft couplings are used in machinery for several purposes, the most common of which are the following. To provide for the connection of shafts of units that are manufactured separatelty such as a motor and generator and to provide for disconnection for repairs or alternations. To provide for misalignment of the shafts or to introduce mechanical flexibility. To reduce the transmission of shock loads from one shaft to another. To introduce protection against overloads. To alter the vibration characteristics of rotating units. Types of shaft couplings Drive couplings A coupling is used to connect two in-line shafts to allow one shaft (driver) to drive the second shaft(driven) at the same speed. A coupling can be rigid or, more normally, it can be flexible allowing relative radial, axial or angular movement of the two shafts. Unlike the clutch the coupling transmission is not designed to engage-disengage as a normal operation Coupling Type Coupling type Description Rigid Flange locked onto each shaft. One flange with recess and the other with matching spigot. Flanges bolted together to form rigid coupling with no tolerance for relative radial, angular or axial movement of the shafts. Muff Coupling Long cylindrical coupling bored and keyed to fit over both shafts. Split axially and clamped over both shafts with recessed bolts. Rigid coupling for transmitting high torques at high speeds Beam Coupling Single piece cylindrical coupling with a hole bored through its entire length. Each end bored to suite the relevant shaft. The helical slot is machined in the coupling in the central region. The reduces the coupling stiffness. The coupling is positive with some flexibility. Pin As rigid coupling but with no recess and spigot and the Bolts replaced by pins with rubber bushes. Design allows certain flexibility. Flexible Rubber disc As rigid coupling except that a thick rubber disc bonded between steel plates is located between the flanges. The plates are bolted to the adjacent coupling flanges. Spider Both half of the couplings have three shaped lugs . When the coupling halves are fitted together the lugs on one half fit inside the spaces between the lugs on the other side. A Rubber insert with six legs fits within the spaces between the lugs. The drive is by the lugs transmitting the torque through the rubber spider spacer This coupling is only used for low power drives. Bibby Coupling The outer flanges of the two half couplings are serrated. A spring fits into the serrations connecting the two halves. Chain Coupling Flanges replaced a sprocket on each shaft. The coupling is by a duplex chain wrapped over both adjacent cnoupling. Gear Coupling Both coupling halves have a raised rim machined as an external gear. The sleeve which couples the two shafts comprises two halves bolted together, each half having a machine internal gear. This coupling requires lubrication. The coupling is capable of high speeds and high power capacity. Metastream Coupling Coupling halves connected via stainless steel diaphragms. High speed high torque capability with good dynamic balance. Single coupling will accommodate angular and radial misalignment and fitted in pairs also allows lateral misalignment. Fluid Coupling Based on both coupling halves having vanes within a housing containing viscous fluid. The rotation is transmitted from one side to the other via the viscous fluid. the coupling provides a soft start. Universal Coupling Coupling which allows large angle between drive halves(20-30o). Generally based on a yoke mounted on each shaft . Between to yokes is mounted a trunnion cross. Needle bearings are used at the bearing points between the cross and the yokes. These type or units are used in pairs on carden shafts. Uses widely on rear wheel drive vehicle propshafts Universal Coupling- Uni-Joint Simplest type of coupling which allows large angle between drive halves. Each side of coupling includes protruding pins. The halves of the coupling are fastened in a pivotting assembly. At all angles up to about 40othe pins interlock with each other and rotation on one half forces the other half to rotate. Low power use only . Not smooth. Not reliable. Really only suitable for remote manual operations. Rigid coupling Rigid couplings are used when precise shaft alignment is required; shaft misalignment will affect the couplings performance as well as its life. Examples: Sleeve or muff coupling Clamp or split-muff or compression coupling Flange coupling Flexible coupling Flexible couplings are designed to transmit torque while permitting some radial and axial and angular misalignment. Flexible couplings can accommodate angular misalignment up to a few degrees and some parallel misalignment. Examples: Bushed pin type coupling Universal coupling Oldham coupling Bellows coupling à ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬ low backlash. Spider or jaw coupling à ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬ elastomeric inserts for flexibility, vibration reduction. Thompson coupling Resilient coupling Disc coupling Some applications like printing machines, roll forming machines, laminating machines, corrugated paper machines and paper making machines require an extreme and variable parallel offset. For these machines the coupling Schmidt-Kupplung is a solution. Torque limiting coupling Torque limiting couplings, or torque limiters, protect systems against overtorque conditions. Requirements of good shaft alignment / good coupling setup it should be easy to connect or disconnect the coupling. it should transmit the full power from one shaft to other without losses. it does allow some misalignment between the two adjacent shaft roation axis. it is the goal to minimise the remaining misalignment in running operation to maximise power transmission and to maximise machine runtime (coupling and bearing and sealings lifetime). it should have no projecting parts. it is recommended to use manufacturers alignment target values to set up the machine train to a defined non-zero alignment, due to the fact that later when the machine is at operation temperature the alignment condition is perfect Tools to measure shaft axis alignment condition it is possible to measure the alignment with dial gages or feeler gages using various mechanical setups. it is recommended to take care of bracket sag, parallaxe error while reading the values. it is very convenient to use laser shaft alignment technique to perform the alignment task within highest accuracy. it is required to align the machine better, the laser shaft alignment tool can help to show the required moves at the feet positions. Coupling maintenance and failure Coupling maintenance is generally a simple matter, requiring a regularly scheduled inspection of each coupling. It consists of: Performing visual inspections, checking for signs of wear or fatigue, and cleaning couplings regularly. Checking and changing lubricant regularly if the coupling is lubricated. This maintenance is required annually for most couplings and more frequently for couplings in adverse environments or in demanding operating conditions. Documenting the maintenance performed on each coupling, along with the date. Even with proper maintenance, however, couplings can fail. Underlying reasons for failure, other than maintenance, include: Improper installation Poor coupling selection Operation beyond design capabilities. The only way to improve coupling life is to understand what caused the failure and to correct it prior to installing a new coupling. Some external signs that indicate potential coupling failure include: Abnormal noise, such as screeching, squealing or chattering Excessive vibration or wobble Failed seals indicated by lubricant leakage or contamination. Checking the coupling balance Couplings are normally balanced at the factory prior to being shipped, but they occasionally go out of balance in operation. Balancing can be difficult and expensive, and is normally done only when operating tolerances are such that the effort and the expense are justified. The amount of coupling unbalance that can be tolerated by any system is dictated by the characteristics of the specific connected machines and can be determined by detailed analysis or experience.

Trifles Essay examples -- essays papers

Trifles Trifles, written in the early 1900’s by Susan Glaspell, is a one-act play illustrating how women can overreact to their own emotions, allowing these emotions to cloud their judgment. This is shown by describing the feelings of two women who are willing to defend a suspect, blame the victim, and go so far as to hide evidence, to protect another woman from being charged with murdering her husband. Mrs. Wright is the suspect in the murder of her husband, who was strangled in his sleep, found with the rope still around his neck. The sheriff and an attorney are examining Mrs. Wrights home for evidence. Mr. Henderson, the attorney, speaking of Mrs. Wright says, â€Å"Here’s a nice mess, ..Dirty towels! Not much of a housekeeper, would you say, ladies?† (Kirszner & Mandell 1166) Mrs. Hale, the suspects neighbor, defends Mrs. Wright immediately saying, â€Å"There’s a great deal of work to be done on a farm. Those towels get dirty awful quick. Men’s h ands aren’t always as clean as they might be.† (1166) She says this even though she hardly knows Mrs. Wright. She admits this when she says, â€Å"I’ve not seen much of her of late years. I’ve not been in this house – it’s more than a year.† (1166) Even so, Mrs. Hale feels protective toward Mrs. Wright and defends her. Mr. Peters, the sheriff, and Mr. Henderson, go upstairs to look for a motive. Mrs. Hale is left talking to Mrs. Peters, the sheriff’s wife, and they begin to put themselves in the shoes of the suspect. Th...

INTRODUCTION In this chapter the pass word stereotypes such as textual passwords, biometric scanning, tokens or cards (such as an ATM) etc.Current authentication systems suffer from many weaknesses. Textual passwords are commonly used; however, users do not follow their requirements. Users tend to choose meaningful words from dictionary or their pet names, girlfriends etc. Ten years back Klein performed such tests and he could crack 10-15 passwords per day. On the other hand, if a password is hard to guess, then it is often hard to remember. Users have difficulty remembering a password that is long and random appearing. So, they create short, simple, and insecure passwords that are susceptible to attack.Which make textual passwords easy to break and vulnerable to dictionary or brute force attacks. Graphical passwords schemes have been proposed. The strength of graphical passwords comes from the fact that users can recall and recognize pictures more than words. Most graphical passwords are vulnerable for shoulder surfing attacks, where an attacker can observe or record the legitimate user’s graphical password by camera. Token based systems such as ATMs are widely applied in banking systems and in laboratories entrances as a mean of authentication. However, Smart cards or tokens are vulnerable to loss or theft.Moreover, the user has to carry the token whenever access required. Biometric scanning is your â€Å"natural† signature and Cards or Tokens prove your validity. But some people hate the fact to carry around their cards, some refuse to undergo strong IR exposure to their retinas (Biometric scanning). In this seminar, present and evaluate our contribution, i. e. , the 3-D password. The 3-D password is a multifactor authentication scheme. To be authenticated, we present a 3-D virtual environment where the user navigates and interacts with various objects.The sequence of actions and interactions toward the objects inside the 3-D environment constructs the user’s 3-D password. The 3-D password can combine most existing authentication schemes such as textual passwords, graphical passwords, and various types of biometrics into a 3-D virtual environment. The design of the 3-D virtual environment and the type of objects selected determine the 3-Dpassword key space. 1. 1 AUTHENTICATION Authentication is the act of establishing or confirming something as authentic, that is, that claims made by or about the subject are true.This might involve confirming the identity of a person, tracing the origins of an artifact, ensuring that a product is what it’s packaging and labeling claims to be, or assuring that a computer program is a trusted one. For example, when you show proper identification credentials to a bank teller, you are asking to be authenticated to act on behalf of the account holder. If your authentication request is approved, you become authorized to access the accounts of that account holder, but no others. 1. 2 AUTHENTICATION METHODS The first i s comparing the attributes of the object itself to what is known about objects of that origin.For example, an art expert might look for similarities in the style of painting, check the location and form of a signature, or compare the object to an old photograph. An archaeologist might use carbon dating to verify the age of an artifact, do a chemical analysis of the materials used, or compare the style of construction or decoration to other artifacts of similar origin. The physics of sound and light, and comparison with a known physical environment, can be used to examine the authenticity of audio recordings, photographs, or videos. The second type relies on documentation or other external affirmations.For example, the rules of evidence in criminal courts often require establishing the chain of custody of evidence presented. This can be accomplished through a written evidence log, or by testimony from the police detectives and forensics staff that handled it. Some antiques are accomp anied by certificates attesting to their authenticity. External records have their own problems of forgery and perjury, and are also vulnerable to being separated from the artifact and lost. Currency and other financial instruments commonly use the first type of authentication method.Bills, coins, and cheques incorporate hard-to-duplicate physical features, such as fine printing or engraving, distinctive feel, watermarks, and holographic imagery, which are easy for receivers to verify. Consumer goods such as pharmaceuticals, perfume, fashion clothing can use either type of authentication method to prevent counterfeit goods from taking advantage of a popular brand's reputation (damaging the brand owner's sales and reputation). A trademark is a legally protected marking or other identifying feature which aids consumers in the identification of genuine brand-name goods. 1. ORGANIZATION OF THE REPORT The 3-D password is a multifactor authentication scheme. To be authenticated, we presen t a 3-D virtual environment where the user navigates and interacts with various objects. The sequence of actions and interactions toward the objects inside the 3-D environment constructs the user’s 3-D password. The 3-D password can combine most existing authentication schemes such as textual passwords, graphical passwords, and various types of biometrics into a 3-D virtual environment. The design of the 3-D virtual environment and the type of objects selected determine the 3-Dpassword key space.ACTUAL RESEARCH WORK 3D PASSWORD SYSTEM 2. 1 OVERVIEW In this chapter the system consist of multi factor authentication scheme. It can combine all existing authentication schemes into a single 3Dvirtual environment. This 3D virtual environment contains several objects or items with which the user can interact. The user is presented with this 3D virtual environment where the user navigates and interacts with various objects. The sequence of actions and interactions toward the objects i nside the 3D environment constructs the user’s 3Dpassword.The 3D password can combine most existing authentication schemes such as textual passwords, graphical passwords, and various types of biometrics into a 3D virtual environment. The choice of what authentication schemes will be part of the user's 3D password reflects the user's preferences and requirements. A user who prefers to remember and recall a password might choose textual and graphical password as part of their 3D password. On the other hand users who have more difficulty with memory or recall might prefer to choose smart cards or biometrics as part of their 3D password.Moreover user who prefers to keep any kind of biometric data private might not interact with object that requires biometric information. Therefore it is the user's choice and decision to construct the desired and preferred 3D password. 2. 2 INNOVATIVE COMPONENT The proposed system is a multi-factor authentication scheme that combines the benefits of various authentication schemes. Users have the freedom to select whether the 3D password will be solely recall, recognition, or token based, or combination of two schemes or more. This freedom of selection is necessary because users are different and they have different requirements.Therefore, to ensure high user acceptability, the user’s freedom of selection is important. The following requirements are satisfied in the proposed scheme 1. The new scheme provide secrets that are easy to remember and very difficult for intruders to guess. 2. The new scheme provides secrets that are not easy to write down on paper. Moreover, the scheme secrets should be difficult to share with others. 3. The new scheme provides secrets that can be easily revoked or changed. 2. 3 COMPARISON WITH CURRENT AUTHENTICATION SYSTEMS Suffer from many weaknesses. Textual passwords are commonly used.Users tend to choose meaningful words from dictionaries, which make textual passwords easy to break and v ulnerable to dictionary or brute force attacks. Many available graphical passwords have a password space that is less than or equal to the textual password space. Smart cards or tokens can be stolen. Many biometric authentications have been proposed. However, users tend to resist using biometrics because of their intrusiveness and the effect on their privacy. Moreover, biometrics cannot be revoked. The 3D password is a multi-factor authentication scheme.The design of the 3D virtual environment and the type of objects selected determine the 3D password key space. User have freedom to select whether the 3D password will be solely recall, recognition, or token based, or combination of two schemes or more. IMPLEMENTATION 3. 1 VIRTUAL OBJECT RECOGNITION Virtual objects can be any object that we encounter in real life. Any obvious actions and interactions toward the real life objects can be done in the virtual3Denvironment toward the virtual objects. Moreover, any user input (such as spea king in a specific location) in the virtual 3Denvironment can be considered as a part of the 3Dpassword.We can have the following objects: 1) A computer with which the user can type; 2) A fingerprint reader that requires the user’s fingerprint; 3) A biometric recognition device; 4) A paper or a white board that a user can write, sign, or draw on; 5) An automated teller machine (ATM) that requests a token; 6) A light that can be switched on/off; 7) A television or radio where channels can be selected; 8) A staple that can be punched; 9) A car that can be driven; 10) A book that can be moved from one place to another; 11) Any graphical password scheme; 12) Any real life object; 3) Any upcoming authentication scheme. The action toward an object (assume a fingerprint recognition device)that exists in location (x1 , y1 , z1 ) is different from the actions toward a similar object (another fingerprint recognition device) that exists in location (x2 , y2 , z2 ),where x1 = x2 , y1 = y 2 , and z1 = z2 . Therefore, to perform the legitimate 3Dpassword, the user must follow the same scenario performed by the legitimate user. This means interacting with the same objects that reside at the exact locations and perform the exact actions in the proper sequence. 3. 2 3D PASSWORD SELECTION AND INPUTSLet us consider a 3Dvirtual environment space of size G ? G ? G. The 3Denvironment space is represented by the coordinates (x, y, z) ? [1†¦ G]? [1†¦ G]? [1†¦ G]. The objects are distributed in the 3Dvirtual environment with unique (x, y, z) coordinates. We assume that the user can navigate into the 3Dvirtual environment and interact with the objects using any input device such as a mouse, key board, fingerprint scanner, iris scanner, stylus, card reader, and microphone. Consider the sequence of those actions and interactions using the previous input devices as the user’s 3Dpassword.For example, consider a user who navigates through the 3Dvirtualenvironment that consists of an office and a meeting room. Let us assume that the user is in the virtual office and the user turns around to the door located in (10, 24, 91) and opens it. Then, the user closes the door. The user then finds a computer to the left, which exists in the position (4, 34, 18), and the user types â€Å"FALCON. † Then, the user walks to the meeting room and picks up a pen located at (10, 24, 80) and draws only one dot in a paper located in (1, 18, 30), which is the dot (x, y) coordinate relative to the paper space is (330, 130).The user then presses the login button. The initial representation of user actions in the 3Dvirtual environment can be recorded as follows: †¢ (10, 24, 91) Action = Open the office door; †¢ (10, 24, 91) Action = Close the office door; †¢ (4, 34, 18) Action = Typing, â€Å"F†; †¢ (4, 34, 18) Action = Typing, â€Å"A†; †¢ (4, 34, 18) Action = Typing, â€Å"L†; †¢ (4, 34, 18) Action = Typin g, â€Å"C†; †¢ (4, 34, 18) Action = Typing, â€Å"O†; †¢ (4, 34, 18) Action = Typing, â€Å"N†; †¢ (10, 24, 80) Action = Pick up the pen; †¢ (1, 18, 80) Action = Drawing, point = (330, 130). Figure 3. 2 – Snapshot of an experimental 3-D virtual environmentThe 3-D password is a multifactor authentication scheme. It can combine all existing authentication schemes into a single 3-D virtual environment. This 3-D virtual environment contains several objects or items with which the user can interact. The type of interaction varies from one item to another. The 3-D password is constructed by observing the actions and interactions of the user and by observing the sequences of such actions. It is the user’s choice to select which type of authentication techniques will be part of their 3-D password. This is chieved through interacting only with the objects that acquire information that the user is comfortable in providing and ignoring th e objects that request information that the user prefers not to provide. For example, if an item requests an iris scan and the user is not comfortable in providing such information, the user simply avoids interacting with that item. Moreover, giving the user the freedom of choice as to what type of authentication schemes will be part of their 3-D password and given the large number of objects and items in the environment, the number of possible 3-D passwords will increase.Thus, it becomes much more difficult for the attacker to guess the user’s 3-D password. Fig 3. 2. 1 State diagram of 3D password 3. 3 3D VIRTUAL ENVIRONMENT DESIGN GUIDELINES The design of the 3 D virtual environments affects the usability, effectiveness, acceptability of 3D password. The first step in building a 3 ­Dpassword system is to design a 3 ­Denvironment that reflects the administration needs and the security requirements. Figure 3. 3 3D virtual environment 1) Real life-similarity ­The prospec tive 3 ¬D virtual environment should reflect what people are used to seeing in real life. Objects used in virtual environments should be relatively similar in size to real objects (sized to scale). Possible actions and interactions toward virtual objects should reflect real life situations. Object responses should be realistic. The target should have a 3 ­D virtual environment that users can interact. 2) Object uniqueness and distinction ­ Every virtual object or item in the 3 ­D virtual environment is different from any other virtual object.The uniqueness comes from the fact that every virtual object has its own attributes such as position. Thus, the prospective interaction with object 1 is not equal to the interaction with object 2. However, having similar objects such as 20 computers in one place might confuse the user. Therefore, the design of the 3 ­D virtual environment should consider that every object should be distinguishable from other objects. Similarly, in desi gning a 3 ­Dvirtual environment, it should be easy for users to navigate through and to distinguish between objects.The distinguishing factor increases the user’s recognition of objects. Therefore, it improves the system usability. 3) Three Dimensional Virtual Environment Size  ­ A 3 ­Dvirtual environment can depict a city or even the world. On the other hand, it can depict a space as focused as a single room or office. A large 3 ¬D virtual environment will increase the time required by the user to perform a 3 ­Dpassword. Moreover, a large3 ­Dvirtual environment can contain a large number of virtual objects. Therefore, the probable 3 ­Dpassword space broadens.However, a small 3 ­D virtual environment usually contains only a few objects, and thus, performing a 3 ­D password will take less time. 4) Number of objects and their types ­ Part of designing a 3 ­D virtual environment is determining the types of objects and how many objects should be placed in th e environment. The types of objects reflect what kind of responses the object will have. For simplicity, we can consider requesting a textual password or a fingerprint as an object response type. Selecting the right object response types and the number of objects affects the probable password space of a 3 ­D password. ) System Importance ­ The 3D virtual environment should consider what systems will be protected by a 3D password. The number of objects and the types of objects that have been used in the 3D virtual environment should reflect the importance of the protected system. APPLICATIONS The 3D password can have a password space that is very large compared to other authentication schemes, so the 3 ­D password’s main application domains are protecting critical systems and resources. 1. Critical servers ­Many large organizations have critical servers that are usually protected by a textual password. A 3-D password authentication proposes a sound replacement for a te xtual password. Moreover, entrances to such locations are usually protected by access cards and sometimes PIN numbers. Therefore, a 3-D password can be used to protect the entrance to such locations and protect the usage of such servers. 2. Nuclear and military facilities- Such facilities should be protected by the most powerful authentication systems.The 3 ­D password has a very large probable password space, and since it can contain token ­, biometrics ­, recognition ­, and knowledge based authentications in a single authentication system, it is a sound choice for high level security locations. 3. Airplanes and jet fighters ­ Because of the possible threat of misusing airplanes and jet fighters for religious, political agendas, usage of such airplanes should be protected by a powerful authentication system. In addition, 3 ­D passwords can be used in less critical systems because the 3D virtual environment can be designed to fit to any system needs.A small virtual envir onment can be used in the following systems like Some other application areas: †¢ ATM †¢ Desktop Computers ; laptop logins †¢ Web Authentication 4. 1 ADVANTAGES * Easy to memorize: Users can memorize a 3D password as a â€Å"little† story which makes the password easy to remember * Flexibility: 3d passwords allows multi-factor authentication. Smart cards, biometrics and alpha num. password can embedded in the 3d password technology * Strength: A scenario in a 3D environment offers as almost unlimited combination of possibilities.As such system can have specific 3d world, hack are extremely difficult. * The 3D password gives users the freedom of selecting what type of authentication techniques. * Secrets those are not easy to write down on paper. * The scheme secrets should be difficult to share with others. * Provide secrets that can be easily revoked or changed. CONCLUSION There are many authentication schemes in the current state. Some of them are based on us er’s physical and behavioral properties, and some other authentication schemes are based on user’s knowledge such as textual and graphical passwords.Moreover, there are some other important authentication schemes that are based on what you have, such as smart cards. Among the various authentication schemes, textual password and token-based schemes, or the combination of both, are commonly applied. However, as mentioned before, both authentication schemes are vulnerable to certain attacks. Moreover, there are many authentication schemes that are currently under study and they may require additional time and effort to be applicable for commercial use.In this report the 3D password mechanism is explained the 3-D password is a multifactor authentication scheme that combines these various authentication schemes into a single3-D virtual environment. The virtual environment can contain any existing authentication scheme or even any upcoming authentication schemes by adding it as a response to actions performed on an object. Therefore, the resulted password space becomes very large compared to any existing authentication schemes. REFERENCES [1] X. Suo, Y. Zhu, and G. S.

First They Killed My Father essays

First They Killed My Father essays Loung Ung was the next to youngest of eight children born into a middle-class family living in Phnom Penh, and the daughter of a former member of the Cambodian Royal Secret Service under Prince Sihanouk. Conscripted as a major into the new government of General Lon Nol, her father was the incarnation of all that the Khmer Rouge wanted to obliterate when they stormed Cambodia's capital city on April 17, 1975, beginning their reign of terror. Fleeing with her family into the countryside, along with thousands of others who were evacuating Phnom Penh, Loung learned the first of many hard lessons. In order to survive, she had to hide her identity, her education, her former life of privilege. It was no longer safe to trust anyone. "To talk is to bring danger to the family. At five years old, I am beginning to know what loneliness feels like, silent and alone and suspecting that everyone wants to hurt me." Posing as peasants, Loung's family moved from village to village, hoping that no one would recognize and expose them as enemies of the Khmer Rouge government. Working 12-14 hour days and barely surviving on their meager rations, they supplemented their diet with roots and leaves or small animals that they trapped. When those became scarce, they caught beetles, crickets, grasshoppers, and frogs for food. "In Phnom Penh, I would have thrown up if someone told me I would have to eat those things. Now, when the only alternative is to starve, I fight others for a dead animal lying in the road. Surviving for another day has become the most important thing to me." Although Loung's three oldest siblings - her brothers, Khouy and Meng, and her sister, Keav-were forced to go to different labor camps, the rest of the family struggled to stay together. After the soldiers came for Loung's father, they separated to survive. Finding her way to a work camp for orphans, Loung began training as a child soldier and was subjected to brainwashing. F ...

The Dancing Raisin Experiment

The Dancing Raisin Experiment Raisins may be dehydrated grapes, but when you add a certain liquid to them they become hip-hoppin’ dancers- at least, thats how they look. To demonstrate the principles of density and buoyancy, all you need is a little carbon dioxide gas  to get those raisins doing the jitterbug. To create carbon dioxide in the kitchen you can use baking soda and vinegar or with the less messy (and less predictable) clear, carbonated soda. Materials This is a low-cost project, and the materials you need are easy to find in the grocery store. They include: 2 to 3 clear glasses (depending on how many versions of the experiment you want to run at the same time)A box of raisinsClear, well-carbonated soda (tonic water, club soda, and Sprite all work well)  or  baking soda, vinegar, and water Hypothesis Start by asking following question and record the answer on a piece of paper: What do you think happens when you put raisins in soda? The Dancing Raisins Experiment Decide whether you want to use soda or baking soda and vinegar to conduct the experiment or if you want to compare what happens in both versions of the experiment. Note: For the baking soda and vinegar version of the experiment, you’ll need to fill the glass halfway with water. Add 1 tablespoon of baking soda, stirring to make sure it dissolves completely. Add enough vinegar to make the glass about three-quarters full, then proceed to Step 3. Put out one clear glass for every different type of soda you’ll be testing. Try different brands and flavors; anything goes so long as you can see the raisins. Make sure your soda hasn’t gone flat and then fill each glass to the halfway mark.Plop a couple of raisins into each glass. Don’t be alarmed if they sink to the bottom; that’s supposed to happen.Turn on some dance music and observe the raisins. Soon they should begin dancing their way to the top of the glass. Observations and Questions to Ask What happened when you first dropped the raisins in the glass?Why did they sink?Once they started dancing, did the raisins stay at the top?What else did you notice happening to the raisins? Did they look different?Do you think the same thing would have happened if you put raisins in water?What other objects do you think would dance in soda? Scientific Principles at Work As you observed the raisins, you should have noticed that they initially sank to the bottom of the glass. That’s due to their density, which is greater than that of liquid. But because raisins have a rough, dented surface, they are filled with air pockets. These air pockets attract the carbon dioxide gas in the liquid, creating the little bubbles you should have observed on the surface of the raisins. The carbon dioxide bubbles increase the volume of each raisin without raising its  mass. When the volume increases and the mass does not, the density of the raisins is lowered. The raisins are now less dense than the surrounding fluid, so they rise to the surface. At the surface, the carbon dioxide bubbles pop and the raisins’ density changes again. That’s why they sink again. The whole process is repeated, making it look as though the raisins are dancing. Extend the Learning Try putting the raisins in a jar that has a replaceable lid or directly into a bottle of soda. What happens to the raisins when you put the lid or cap back on? What happens when you take it back off?

Explain the differences between a group and a team Assignment

Explain the differences between a group and a team - Assignment Example The formation of group is easy than a team. If an auditorium is filled with medical professionals, they could be grouped according to gender, expertise, experience, age, specialty etc. The effectiveness is a different issue. In the group total comparability is only the ideal, it rarely occurs. When points view of the group members differ, achieving consensus is a difficult task for a leader. A team is a responsive unit and formed to achieve a particular goal or group of functions. A team leader is seized of the final goal of the team, in advance. Though the process of forming a them is difficult, may involve much spadework, deliberations and consultations, once the profess is accomplished, the working is smooth. There is not much room for differences as the final objective is the same. Take for example a construction team. It may consist of an architect, an accountant, an engineer, a supervisor, a sales manager and a secretary. A collection of people and counseling them for a cause does not evolve them into a team. Teams have definite features that set them apart from group. Generally, a team consists of a small number of individuals, with complimentary skills and all of them are committed for a common purpose, they have target-oriented performance goals. They have a common approach and as such they consider themselves mutually accountable. They are a responsive and responsible unit. The membership of a team is definable, generally not more than twelve. Their functioning is mutually dependent and they can be compared to the steps of a ladder. They know the import and importance of the term â€Å"we† than the syllable â€Å"I.† The working of the team is dynamic, the performance is measured directly and the collective work products are linked to financial performance of the business. The results can be quantified, everyday, when necessary. The team meetings are held often, the problem-solving is taken up

They have tried to pick up the standards, reduce them to the basic concepts, simplify the language and support their learners both in English and content classes. The reason for necessity of such cooperation is that the new standards of education presuppose harmonic development of an educated person, and this diversity is impossible without inter-subject relationships. In this regard, both a native speaker and a learner of English as a second language have the same objectives – reading and understanding complex texts, finding written and oral arguments, engagement in conversations. It is obvious that the students with low skills in English take much time from their tutors in content subjects, and this is the fact which also proves necessity of cooperation between the two mentioned types of teachers. Practice shows that teachers of English as a second language support the idea of their assistance to the content teachers who may need it when working with the learners of English. This is because English teachers are familiar with the learners’ language capabilities, knowledge level and cultural background, and this information plays a very important role when choosing an appropriate approach to better ways of explanation of the content subjects. The author also concerns herself with the matter of the English teachers’ status in their educational institutions. They are considered the main responsible for formulating language competence of the learners, they must work extra time to equalize the students’ language knowledge level, that is, they have many responsibilities and their scope of work is very large. The dilemma here is that they are rarely awarder for this, for example, the number of principles who are English teachers is very low, and almost all of the leading roles in the

In the light of the intrinsic facets of social marketing, as mentioned above and as has been observed in the case of Hindustan Unilever Limited (HUL), the current report will aim at elaborating the key elements of a successful marketing campaign and while doing so, it will take into account the target markets, the required promotional activities, and the incorporation of a marketing plan.

Ethnography on Middle Class American Male Essay Example for Free

Ethnography on Middle Class American Male Essay Two centuries ago leading white, middle-class families in the newly united American states spearheaded a family revolution that replaced the premodern gender order with a modern family system. But modern family was an oxymoronic label for this peculiar institution, which dispensed modernity to white, middle-class men only by withholding it from women. The former could enter the public sphere as breadwinners and citizens, because their wives were confirmed to the newly privatized family realm. Ruled by an increasingly absent patriarchal landlord, the modern, middle-class family, a woman’s domain, soon was sentimentalized as traditional. It took most of the subsequent two centuries for substantial numbers of white working-class men to achieve the rudimentary economic pass book to modern family life a male family wage. By the time they had done so, however, a second family revolution was well underway. Once again middle-class, white families appeared to be in the vanguard. This time women were claiming the benefits and burdens of modernity, a status they could achieve only at the expense of the modern family itself. Reviving a long-dormant feminist movement, frustrated middle class homemakers and their more militant daughters subjected modern domesticity to a sustained critique. At times this critique displayed scant sensitivity to the effects our antimodern family ideology might have on women for whom full-time domesticity had rarely been feasible. Thus, feminist family reform came to be regarded widely as a white, middle-class agenda, and white, working-class families it’s most resistant adversaries. African-American women and white, working-class women have been the genuine postmodern family pioneers, even though they also suffer most from its most negative effects. Long denied the mixed benefits that the modern family order offered middle-class women, less privileged women quietly forged alternative child rearing. Struggling creatively, often heroically, to sustain oppressed families and to escape the most oppressive ones, they drew on traditional premodern kinship resources and crafted untraditional ones, lurching backward and forward into the postmodern family. Rising divorce and cohabitation rates, working mothers, two-earner households, single and unwed parenthood, and matrilineal, extended, and fictive kin support networks appeared earlier and more extensively among poor and working-class people. Economic pressures more than political principles governed these departures from domesticity, but working women like Martha Porter and Dotty Lewison soon found additional reasons to appreciate paid employment. Popular images of working-class family life, like the Archie Bunker, rest on the iconography of unionized, blue-collar, male, industrial breadwinners and the history of their lengthy struggle for the family wage (Stacey 30). But the male family wage was a late and ephemeral achievement of only the most fortunate sections of the modern industrial working class. Most working-class men never secured its patriarchal domestic privileges. Postmodern conditions expose the gendered character of this social-class category, and they render it atavistic. As feminist have argued, only by disregarding women’s labor and learning was it ever plausible to designate a family unit as working class. In an era when most married mothers are employed, when women perform most working-class job, when most productive labor is unorganized and fails to pay a family wage, when marriage links are tenuous and transitory, and when more single women than married homemakers are rearing children, conventional notions of a normative working-class family fracture into incoherence. The life circumstances and mobility patterns of the members of Pamela’s kin set and of the Lewisons, for example, are so diverse and fluid that no single social-class category can adequately describe any of the family units among them. If the white, working-class family stereotype is inaccurate, it is also consequential. Stereotype is moral stories people tell to organize the complexity of social experience. Narrating the working class as profamily reactionaries suppresses the diversity and the innovative character of many working-class kin relationships. The Archie Bunker stereotype may have helped to contain feminism by estranging middle-class from working-class women. Barbara Ehrenreich argues that caricatures which portray the working-class as racist and reactionary are recent (Handel 655), self-serving inventions of professional, middleclass people eager to seek legitimating for their own more conservative impulses. In the early 1970s, ignoring rising labor militancy as well as racial, ethnic, and gender diversity among working-class people, the media effectively imaged them as the new conservative bedrock of middle America. Thus, All in the Family, the 1970s television sitcom series that immortalized racist, chauvinist, working-class hero-buffoon Archie Bunker, can best be read, Ehrenreich suggests, as the longest-running Polish joke, a projection of middle-class bad faith. Yet, if this bad faith served professional middle-class interest, it did so at the expense of feminism. The inverse logic of class prejudice construed the constituency of that enormously popular social movement as exclusively middleclass. By convincing middle-class feminists of our isolation, perhaps the last laugh of that Polish joke was on us. Even Ehrenreich, who sensitively debunks the Bunker myth, labels starting the findings of a 1986 Gallup poll that 56 percent of American women considered themselves to be feminists, and the degree of feminist identification, was, if anything, slightly higher as one descended the socioeconomic scale. Feminist must be attuned to the polyphony of family stories authored by working-class as well as middle-class people if they are ever to transform data like these into effective political alliances. While the ethnographic narratives in this research demonstrate the demise of the working-class family, in no way do they document the emergence of the classless society postindustrial theorists once anticipated. On the contrary, recent studies indicate that the middle classes are shrinking and the economic circumstances of Americans polarizing. African-American has borne the most devastating impact of economic restructuring and the subsequent decline of industrial and unionized occupations. But formerly privileged access to the American Dream in the 1960s and 1970s, now find their gains threatened and not easy to pass on to their children. While high-wage, blue-collar jobs decline, the window of postindustrial opportunity that admitted undereducated men and women, like Lou and Kristina Lewison and Don Frankin, to middle-class status is slamming shut. Young white families earned 20 percent less in 1986 than did comparable families in 1980, and their homeownership prospects plummeted. Real earnings for young men between the ages of twenty and twenty four dropped by 26 percent between 1980 and 1986, while the military route to upward mobility that many of their fathers traveled constricted. In the 1950s men like Lou Lewison, equipped with VA loans, could buy homes with token down payments and budget just 14 percent of their monthly wages for housing costs. By 1984, however, carrying a median-priced home would cost 44 percent of an average male’s monthly earnings. Few could manage this, and in 1986 the U. S government reported the first sustained drop in home ownership since the modern collection of data began in 1940. Thus, the proportion of American families in the middle-income range fell from 46 percent in 1970 to 39 percent in 1985. Two earners in a household now are necessary just to keep from losing ground. Data like these led social analysts to anxiously track the disappearing middle class, a phrase that Barbara Ehrenreich now believes in some ways missed the least from the middle range of comfort. Conclusion The major arena to which expert turned in their examination of postwar masculinity was the American family, placing a spotlight upon men’s roles as husbands, fathers, and family heads. It was commonly noted by social scientist and delineators of American character that men had lost much of their former authority within the family. Indeed, the typical American male, as described by the anthropologist Geoffrey Gorer, was seen as having so completely given up any claim to authority that the family would constantly risk disintegration and disaster if not for the efforts of his wife (Reumann 66). On the other hand, commentators diagnosed an assault on middle-class manliness and warned of its effects on the nation and its culture. Obsessively rehearsing a narrative of nationwide decline, social disarray, and familial and gender collapse, they pictured a country in which masculinity had become a besieged and precious resource.

Free Essays - All Quiet on the Western Front :: All Quiet on the Western Front Essays

All Quiet on the Western Front Erich Maria Remarque's All Quiet on the Western Front is one of the greatest war novels of all time. It is a story, not of Germans, but of men, who even though they may have escaped shells, were destroyed by the war. The entire purpose of this novel is to illustrate the vivid horror and raw nature of war and to change the popular belief that war is an idealistic and romantic character. The story centers on Paul Baümer, who enlists in the German army with glowing enthusiasm. But in the course of war, he is consumed by it and in the end is "weary, broken, burnt out, rootless, and without hope." Through Baümer, Remarque examines how war makes man inhuman. He uses excellent words and phrases to describe crucial details to this theme. "The first bomb, the first explosion, burst in our hearts." Baümer and his classmates who enlisted into the army see the true reality of the war. They enter the war fresh from school, knowing nothing except the environment of hopeful youth and they come to a premature maturity with the war, their only home. "We were eighteen and had begun to love life and the world; and we had to shoot it to pieces. We are not youth any longer." They have lost their innocents. Everything they are taught, "the world of work, duty, culture, and progress" are not the slightest use to them because the only thing they need to know is how to survive. They need to know how to escape the shells as well as the emotional and psychological torment of the war. The war takes an heavy toll on the soldiers who fight in it. The terror of death will infest the minds of soldiers and bring about horrible images of death and destruction until they break down and go to pieces. "Every hour and everyday, every shell and every death cuts this thin [line of sanity], and the years waste it rapidly." In these dangerous moments, anybody would have gone mad, have deserted their post, or have fallen. It takes a special kind of soldier to deal with this emotional abuse; a soldier who will not go to pieces at the sight of a mutilated body; it takes a soldier like Baümer. Baümer has "grown accustomed to it; war is the cause of death like influenza and dysentery.

Education Should No Longer Be Imparting of Knowledge Essay

â€Å"We must turn to the child as the key to the fate of our future life† (http://www. montessorisynergies. com/synergies/transformation/wisdom-of-montessori) [Accessed 5th May, 2013] The above quotation shall be explored & revealed in the further contents of this essay. To begin with, let us first start with a brief current scenario of education in our society. Current scenario of education â€Å"The school must mean something else than a place of instruction, where the one teaches the many, with pain on both sides, an effort carrying with it little success†. The schools today exist to transmit knowledge though teachers and the role of the students is to absorb this knowledge and get awarded as per their marks. The education today that we have in our society is primarily interested in defining the curriculum and establishing high standards. The focus on the needs of the individual learner is hardly seen. The issues such as how the children actually want to learn, how they need to be taught, what are they actually interested in learning about are considered irrelevant. Need of our society The need of our world today is a society that has peace, patience, tolerance, happiness, health, nonviolence, betterment of the mankind, safety, non-corruption, no poverty, and no racial discrimination. It needs a man who is active, attentive, confident, curious, expressive, helpful, honest, innovative, judgmental, observant, organized orientated, patient & socially active. Who is a human being? A human being is a unified personality who comes into being from a child through the years of infancy, toddlerhood, preschool & adolescence. Ultimately, child is the one who produces the man. The child before birth nside the mother’s womb grows only physically. After a child is born he starts developing mentally & completes his psychic growth outside the womb. When the birth of the child takes place; he has some hidden qualities in him which cannot be seen. As he continues to grow, he slowly starts revealing himself & starts showing these potentials/abilities. In order to have a society with attributes as mentioned earlier & which in turn needs a man with the required qualities, it is very important to focus ourselves on the development of the child to help him release his potentials since he is the maker of the man. Hence, there is an urgent need to focus on a new system of education based on the idea of freedom for the child within a carefully planned & structured environment. It is important to recognize the crucial importance of a child’s first years of development. It is during this time that a child’s power of absorption is the highest & permanent attitudes of learning are formed & which establish the person he will be in future. Dr. Maria Montessori, the great pioneering influential realized this need and developed the Montessori Education. As proposed by Dr Maria Montessori, it shall be now briefly discussed all the phases to be looked into to create this new system of education & how the focus on the right aids during each of these phases, help the child’s future development. The Absorbent Mind The child has a creative intelligence that exists in his unconscious mental stage. During the unconscious stage (0 to 3 years), he absorbs whatever is available in his environment. He learns to speak, to walk and gain control of his hands. Hence it is very much necessary to provide a carefully planned environment to the child since he will see and learn whatever is there in his environment. For e. g if we have an aggressive environment around him at home i. e. there is no calmness & peace, the child tends to develop as an aggressive personality since he absorbs that trait from his environment. After 3 years, the child enters into the period of conscious absorption. He starts applying now the functions that were created in the unconscious stage and has developed a will & memory. This helps him in developing his reasoning & concentration skills. He uses his hands & starts working and by means of work his ability develops to choose actions independently. He wants to do everything by himself. He starts developing an urge to become social & starts involving with peers as well which make him a good social being in the long run. Sensitive periods The child passes through a special time in which he is interested in one unique characteristic of his environment known as sensitive periods. He can easily develop this interest into ability if he is given the right environment & freedom. These periods are critical to a child’s self-development & interrupting a child while he is in the middle of a sensitive period can result in a powerful emotional response. He passes through the sensitive periods of order, movement, language, senses, small objects & social aspects. As we see further below, we realize that the right environment & freedom given to the child during each of these periods provide a strong base to lay the foundation of a well-developed human being. The child seeks order so he can adapt himself to his environment. For e. g. If a child who comes home from school, has a habit of seeing all the things at place & has his belongings are accessible to him & and one day the settings at home are changed completely, nothing is at the same place as earlier, the child starts showing a dislike. This disorder can be an obstacle to his development. The order helps him to orientate himself. He becomes organized & systematic which is a crucial requisite for his development. Another sensitive period that the child goes through is the sensitivity to five senses. The child is developing his senses & his attention is therefore directed towards the observation of the objects in his environment. In order to help him this development, Sensorial subject was introduced in the Montessori education to enable him to explore different attributes of the environment. By using all his basic five senses, the child is able to explore the qualities of the objects in his environment, with separate materials. For e. g. a child using his tactile(touch) & visual sense is able to explore the different dimensions of an object i. e. height, diameter etc. The usage of these materials develops in child the qualities of attention, experiment, observation, exploration, judgement & comparison. The sensitive period of movement is also very important for the child development. The child has started learning to crawl, walk, jump, climb, swing around & carry things and wants to perfect his movement. Hence it is important to provide the right environment & give freedom to develop his fine & gross motor skills for his life. He should be not stopped or provided help when he is able to do the activity himself. Foe e. g. if he is able to walk himself up till a point, we should not stop & pick him up just because we are not able to reach quickly to our destination. This makes the child frustrated & breaks his concentration. He does not gain the self-control & self-independence. The other sensitive period is to small objects. The child keeps observing all the small details around him. He focuses on the army of ants in the playground, the leaves, the flowers, everything around him which makes him to focus. He also wants to know the reason for all these activities which make him curious & intuitive. It is very important to answer his questions since discouraging his curiosity makes him less observant & lazy which will be followed till he becomes an adult. Sensitivity to language is another very important aspect. During this time the child is sensitive to the words around him & absorbs them. He takes in sounds, words to acquire language which is a pre requisite for the child to form into a man. The Montessori environment provides a rich vocabulary & right pronunciation to the child which helps him in refining his language. This makes him a good speaker, writer, reader & confident which develops his self-esteem. The Environment â€Å"Especially at the beginning of life must we, therefore, make the environment as interesting & attractive as we can† (The Absorbent Mind, Chapter 9, Page 103) Environment refers to the surroundings in which the child is growing. The environment needs to be very rich & it should provide all the things required for the child to develop since he has an absorbent mind & the sensitive periods. The Montessori environment includes the children, the teacher & the materials and offers the important elements for the optimal development of the child. Here is a brief discussion on these –  ·Beauty, order, reality & simplicity –The environment follows the concept of reality. The materials are real since the child has to ultimately face them in the real world later. Children are given freedom to work & speak with other children. This helps them to socialize. They are taught to respect the other children (should not disturb the other children), respect the material (should not destroy the material) and respect the the environment (should not hurt others and treat children/teachers with grace & courtesy).  ·The mixed age group children in a Montessori school encourage the social development & moral values of the children. The little ones learn from the older ones & the older ones learn by teaching the younger. I would like to state an example here from the observation I did for the child development. A younger child aged 2 1/2 years fell down from the swing in the play area. An older boy almost 4 years old quickly came to pick him up & consoled him not to cry. The mixed age group also removes competition. The Teacher The teacher is a growing person, always ready to learn new things & increase her self-knowledge. She should be mentally active & physically passive which means that she should have the capacity to observe that the child is in which state of development. The objects, not the teaching given by the mistress, form the principal agent, and it is the child who uses them, who is the active being, not the teacher† (The Discovery of the Child, Chapter 11, Page 179) Maria Montessori believed that the teacher’s duty is to let the child choose an activity himself by using the materials according to his own needs and interest. In this way, the materials become his object of development. She should not force the child to do a particular activity rather just act as a source of guidance & provide him the freedom to perform. Further to the above, a teacher must possess the following attributes in her – Respect for the child, should be able to channelize the potentials of the child in the right direction, clear all the obstacles in his development, social qualities such as friendly, understanding and tolerant. An addition, are the Laws of Development that are used by the child for revealing himself. These are described briefly as below – Law of work – Children start gaining all the qualities of patience, discipline & attention through the work with the materials. It is the magic of the work through the materials that enables them to use their energies in constructive development. Children keep on repeating the task till they achieve perfection. For e. g we can observe at home that if we give a small child a task of dusting a table, he will keep on doing it till he masters himself in cleaning the smallest particle of dust. Hence it is the work through the repetition & practice that he gains perfection. Law of independence – To be independent, a child should be allowed to work himself if he is able to, without the immediate help of others. The more he works himself, the more independent & self-confident he becomes. The independence can be given in the ways of – giving the opportunity to work with the materials (activities such as tie laces, button/unbutton, zip/unzip ), should be allowed to do things on his own for his personal care & hygiene like dressing, bathing, brushing hair & teeth and should be allowed to take decisions for himself for instance, for a club activity, we should let the child choose an activity as per his own interest rather than force him to choose something just for our own content. This will suppress the interest & affect the decision making ability of the child in the long run. Development of intelligence – Intelligence means application of knowledge. It is an ability to differentiate & make judgment. The sensorial materials are such that they help the child to focus on one quality. For e. g. the cubes in the pink tower are all of the same colors & concentrate only on the size. The focus of the child’s mind on one attribute leads him to make a comparison of the objects, thus helping him in developing his comparison & judgmental skills. Development of imagination & creativity –Imagination & creativity are inborn powers in the child that develop as he interacts with the environment. Imagination is based on something that we have experienced in the past. The cultural activities in a Montessori environment such as construction, technology, science, math, language, art & craft, music & imaginative play help to foster imaginative skills thus helping him in his future development. Development of emotional & spiritual life – A child needs a warm & loving environment to meet his emotional & spiritual needs. Through the daily life practical exercises in the Montessori environment, they are taught to be courteous & considerate. They learn how to share since there is only one single material for each activity & also develop patience since they need to wait for their turn once a child already working with the material finishes his activity. It was also observed that while working with the materials they undergo a stage where their physical & mental developments are both harmonized known as normalization. The prepared Montessori environment facilitates the process of normalization by offering materials. The normalised children have love of order, love of work, concentration, attachment to reality & nature, love of silence, obedience and self-discipline Dr. Maria Montessori was also able to identify the important tendencies (behavioral patterns) that compel the human beings to construct & refine themselves. These patterns are the ones that children isplay naturally and should be considered when preparing the environment – Exploration, order, communication, work, concentration, repetition, perfection, self-control, creativity & independence Children raised in environments prepared according to the basic human tendencies as above, tend to be secure, healthy, and happy children. The Parent â€Å"Parents have a very important mission. They are the only ones who can save their children by uniting & working together for the improvement of society† (The Secret of Childhood, Chapter 30, Page 215) Parenting is the most pleasurable & the most challenging job. Parents must protect their child & have a deep concern for him. They should take care of the below errors –  ·Showering with material goods – Should not equip their child with mobiles, videogames etc. as a substitute for the time & attention desired by him.  ·Unnecessary dependence on caretakers – Should not rely on caretakers since they themselves are too busy to devote time to their child.  ·Unrealistic praise – Should not offer unrealistic praise to their children in the form of compliments. When children fail to receive such compliments from the rest of the world, they become confused & lose their self-esteem. Paying more attention to negative behavior – Parents should not overlook their children’s good behavior & punish them for their bad behavior. Things such as not doing homework, poor marks, mess at home direct more attention of the parents. Thus children get more attention for being bad & hence try to keep on doing bad activities to get attention. This work will be an interest to parents, teachers & policy makers that attention to young children’s physical, emotional, social, moral development is very much important. A child is a mystery. He has the highest potentialities but we cannot make out that who he will be in future unless we help him in releasing these. He has his own natural powers to develop. His unknown energy within him can be utilized for the betterment of the mankind. Giving him the freedom and support to question, the child will become confident & enthusiastic. A method of schooling that will focus on personal development will produce more mature, creative and socially adept children. The verbal teaching as in today’s schools being substituted by Sensorial materials, which contain a control of error will permit the child o teach himself by his own effort.
