Executive summary This report discusses how management prepares them to anticipate change in the business environment in the long run and short run too. Change is very important for each and every organization in today’s world because world today has become a daily changing place and in order to keep pace with the changing world we need to bring about a constant change in our organizations, too. There are certain methods by which the senior management can prepare them for anticipating the need for change. The first method is by doing a detailed research and studying for the change. The second method involves having the awareness about the ever changing needs of people and the change process. The third method discusses about having a complete understanding about the compulsion and urgency for change. Lastly, being mentally tough for the change process is the fourth method to prepare the management for anticipating change in the short and long run. Introduction: Change is a constant and ingoing process in an organization. Change can be defined as one of the many characteristics of organization development. The change efforts are based on the analysis of particular problems and their purpose is to attain specific goals. Change is not an easy thing to implement and anticipate. It is a difficult and a challenging process; therefore the management has to take certain steps in order to prepare them for antedating the change in business environment. The senior management can prepare themselves for a change through studying and researching about change, by having a sound awareness about the change process and by understanding the necessity of change and by being mentally tough about the change process. All in all, a constant change is ... ...reparing them for anticipating the need for change that will be necessary for the organization. This is most applicable for the long run change because if the senior management is working for the environment today they will be efficient to keep a check on the long range changes too, that are being forecasted for the future. Conclusion: Change is required for all types of organizations and in every field. Whether the change is long range or short range the senior management will have to prepare them for the change process.

Hunger in San Diego Persuasive Speech

1 | Page . Attention Step . When will you eat next? Will you be eating dinner tonight? . Need Step . Today, there are over 446,000 people that are going hungry in San Diego County. http://sandiegofoodbank. org/hunger-in-san-diego/ . A story of a fellow San Diegan and her family who are also having hunger problems. 1. Alejandra in her late 20s moved in with her sister Marisol, her husband, and her three kids to help take care of them. 2. Marisol worked days and Alejandra nights so there was always someone to take care of the kids. 3.Marisol’s husband lost his job as construction worker, Marisol was laid off from hers as a housekeeper at a Holiday Inn, and then Alejandra lost her restaurant job. 4. It became hard for them to find work, but eventually Marisol’s husband found few jobs as a handyman and Marisol worked cleaning a few houses. 5. Barely got by, and it was hard for them. 6. Cupboards were generally empty except for a little of rice and beans. 7. Main concern was children, so adults would often eat little or nothing at all so the kids would have enough. . Eventually got support from church and then San Diego Food Bank. †¢ Here is a picture of Alejandra picking up food at the San Diego Food Bank. That is a real story about a real hunger problem. http://sandiegofoodbank. org/newstypes/client-profiles/ 2. Feedingamericasd. org says that: †¢ 1 out of 4 children in San Diego don't know where their next meal is coming from†¦ †¢ Scientific evidence suggests that hungry children are less likely to become productive citizens. A child who is unequipped to learn because of hunger and poverty is more likely to be poor as an adult. . You see†¦. our bodies are like engines, engines need fuel, we need food, and both are required to move forward. 2. So next this quote is from sandiegohungercoalition. org, Ken Hecht, executive director of California food policy advocate says that: â€Å"Given the extent of food insecurity in San Di ego County and across the country, we must not undermine critical efforts to protect families against hunger, and improve health through good nutrition,† You know†¦.. we must all realize that hunger can happen to any of us, all it takes is: †¢ Losing our job †¢ Having a health crisis †¢ Or any other unusual emergency expense. Such as a major car repair. ?And†¦ We must all be aware†¦That it’s important that San Diego County has food bank agencies to provide support to people who are low income or have sudden crises. . Satisfaction Step . We†¦.. Should look for opportunities†¦ to support the San Diego Food Bank. . There are many ways to support the Food Bank, we can†¦ †¢ Donate food items Support them financially †¢ Or we can volunteer. . aThe San Diego Food Bank has been around since 1977 and has been serving ever since because of†¦ People’s food†¦ financial†¦ and voluntary support. . So†¦Y es, this solution will take time out of your day and/or money if you would like to help. But, think of the good you would do by simply donating 10 dollars, taking 3 hours out of your Saturday or Sunday, or even collecting a few cans of food from your neighbors or workplace to just do something good for a local family in need. Visualization Step . So†¦just look around places you go in San Diego, maybe you see a homeless guy asking for money for food, or maybe it’s your next door neighbor who doesn’t have enough to eat, or maybe even a friend who’s hungry but too reluctant to say. †¢ The sad fact is that nearly half a million people in San Diego County don’t have enough to eat. . Imagine that there was a place where all of those hungry people could go to get food. I know of a place, the San Diego Food Bank. . Action Step . Fact is†¦people are hungry†¦. ut the San Diego Food Bank is there to help. . So today, I would like to encourage you to pull out your phones when you leave this classroom today, simply text capital letters â€Å"SD† to 20222, and this will make a 10$ donation to the San Diego Food Bank, just a simple thing, yet that 10 dollars will provide 30 meals for people in need. . This week, I myself am going to make a ten dollar donation and drop off a bag of food to the Food Bank. . If San Diegans work together, we can eliminate hunger in San Diego County.

Sia Singapore Airline

Executive Summary The report provides an overview of the company and its environment. The paper identifies various resources and capabilities available to the company. The various strategies that Singapore Airlines utilise and how they affect the airlines performance. Key issues have been identified that threaten Singapore Airlines current market. The often complicated Government regulations and global laws that affect the airline industry have been defined and explained. Current industry issues and trends that affect Singapore Airlines have been researched, a number of recommendations have been provided, as a possible solution.Overview of Singapore Airlines Singapore Airlines (SIA) first flights began in 1947 partnered with Malaysian Airlines, each funded by there governments. The two airlines mainly serviced South East Asia. Singapore separated from Malaysia in 1965 to become the republic of Singapore. The two governments therefore decided to go there own ways and set up there own airlines. In 1972 Singapore Airlines was launched. The domestic market was basically non existent due to Singapore being a small country geographically.Singapore Airlines had to immediately pursue an international presence and started planning flight routes, airport resources, and government acceptance into foreign destinations etc. SIA also had to establish themselves as a genuine competitor and market the airline internationally to potential customers and future stakeholders. Today, SIA has more than 10,000 employees and 95 aircrafts. The airline now serves 89 destinations around the world including Asia, Europe, North America, Middle East, Australasia, and Africa. ( www. airlines. priceline. om) SIA is situated at Changi Airport along with subsidiaries Silkair and Tiger Airlines. ‘In 2004, Changi Airport received a record 30,400,000 passengers, a year-on-year growth of 23. 1% in passenger traffic. Similarly, a record 1,780,000 tonnes of cargo was moved, representing a year- on-year increase of 10. 2% in airfreight volume’. (http://en. wikipedia. org). Changi Airport is classed as â€Å"the hub of Asia†, Changi provides stopovers, refuelling, and passenger exchange for all the international airlines travelling from one side of the world to the other.Changi Airport is also expanding to accommodate for there cut price airline and new Airbuses arriving in 2006. Analysis of Singapore Airlines Environment In analysing the environment, the important external influences that effect performance and decisions of Singapore airlines have been detailed in this section. The airline industry has been strongly controlled by agreements and policies. Airlines couldn’t just fly to any destination or country without appropriate authorisation. Most countries have there own national airline that are generally government backed and hold a big influence on there operation.The governments also implement policies and regulations to control foreign airline a ccess to there airports. Some countries now have deregulated there national airline industry to reduce the amount of government control, and make access to airports/services more open for negotiation. Countries that have employed this action are the United States, Australia, European Union and Japan. The deregulation of the Airline industry opens doors for more entrants to the market and increased competition.Singapore Airlines is still owned by the Singapore government and is still affected by such controls. The Singapore government has signed an agreement with the United States called â€Å"Open Skies† that gives both countries unrestricted flight access to each others countries. The open skies phenomenon is gathering momentum and more and more countries are signing up. Singapore Airlines is currently in negotiations with Australia, to reach an agreement regarding open skies access down under. Basically the countries that gain open skies agreements are able to expand on exi sting business.The airline industry is highly competitive industry and the rival airlines are always taking advantage of any opportunity to gain more destinations. Statistics show Asia’s population is steadily increasing every year and this contributes to the increase in flights. Asia is recognised as the hotspot for air travel at present and into the future. Asia-Pacific intercontinental flights are up 7% and there has been growth of 8% intra-regional services (www. oag. com). This interest in the area has seen new cut price airlines emerge to cater for the demand. SIA has established its own low price airline Tiger Airlines to satisfy demand.Other environmental factors influencing SIA and the airline industry are rising fuel prices. The price rise in fuel causes a cost increase in the running of flights, therefore a rise in ticket prices. SIA have just passed a decision to put a US$10 surcharge on ticket prices to accommodate the fuel rise. Terrorism has caused massive econ omic losses for airline industry and also bankruptcy. Terrorism strikes happen at any time without warning and destinations around the world that are directly affected by terrorism attacks see a dramatic stop in airline flights.The airlines cannot predict these attacks from happening and have to build such occurrences into there risk management policies. Review of the Industry Structure In analysing the industry structure this report uses Porters 5 Forces. The five forces look at the Threat of New Entrants, Power of Suppliers, Power of Buyers, Availability of Substitutes, and Competitive Rivalry. Threat of New Entrants: The international airline industry has high barriers to entry for a number of reasons, firstly there are quite high costs involved in setting up an industry.As mentioned previously, gaining flight access to foreign countries and obtaining airport space is another hurdle that stands in the way of new entrants. The current airlines dominating the industry are constantl y working on maximising cost efficiency, and performance to discourage any new entrants and to try force out existing poor operators. The Domestic industry is more attractive to new entrants as it doesn’t have as much complications as the international side and lower barriers to entry. Power of Suppliers: The aircraft suppliers of the airline industry are dominated by two suppliers Boeing and Airbus.The aircrafts engines are standardised so both aircraft manufacturers have similar engines. Boeing and Airbus both outsource there parts for there planes and generally use the same suppliers. The body frames and interiors is where the two manufacturers can differentiate there product. Due to the standardisation of engines the switching costs of suppliers is reduced and airlines. (De Melo, 2000) Power of Buyers: The power of buyers is low in the airline industry as switching costs are high. Most airlines are similar inside; it’s more the service that sets them apart.Most air lines follow each other on prices and cause buyers to pay there price, on the other hand new entrants my cause price competition and therefore a buyers market. (www. fool. com). Availability of Substitutes: The substitutes that could threaten the airline are cars, boats and trains. These substitutes are not that much of a threat to aeroplane travel. Airlines are generally is used to cover large distances in a short period of time, and was establish to fill a demand that the other forms of travel couldn’t accommodate as effectively.Alternate measures of transport are more of a personal choice not a direct parallel substitute. (www. fool. com). Competitive Rivalry: The airline industry is highly competitive and price wars are a common occurrence. There is constant fighting for territory and expansion. Major players in the industry concentrate on lowering there costs and improving service to deter new entrants. What Key resources available to Singapore Airlines? Singapore Airlin es is a well establish international airline with strong profitable track record.The company has a government ownership and also private stakeholders. The airline has always been profitable and the funds reinvested back into the company, to build on capital. The table below shows that last 3 years financials and even in the case of the S. A. R. S breakout in 2004 they still posted a profit. [pic] Aside from just financial capital, Singapore Airlines has many other resources listed below: †¢ Changi airport the home of Singapore Airlines is one of the largest freight handling facilities in the world, and is the most popular hub in Asia. †¢Singapore has a resource of about 95 aircrafts that now are brought internally and not leased; the aircrafts are generally replaced every 4-5 years. †¢ Singapore Airlines has built a mass of 89 international flight destinations. †¢ The airline has built a human resource training facility. †¢ Changi Airport hosts SIA state of art engineering company that services there planes and other international airlines. SIA also has one of the largest flight kitchens in the world situated at Changi. †¢ SIA belongs to the Star Alliance where other airlines join resources together to increase coverage around the world.Star alliance covers 790 airports in 138 countries. †¢ Finally the brand attribute, is probably there most powerful resource. â€Å"Singapore Girl you’re a great way to fly† Has been strongly nurtured over the last 32 years to be the most recognised brand and icon in the airline industry, Singapore Airline has many capabilities that support there resources, these are: †¢ Latest technological and communication products linking there global network. †¢ Huge investment in human resources, this provides highly skilled workers and management. †¢ Expansive destination coverage due to Star Alliance. State of the art freight facilities that link with the port shipping auth ority What it takes to be successful in the Airline Industry and What strategies are used by Singapore Airlines? Singapore Airlines is basically the trend setter of the airline industry. SIA has employed many innovative strategies since it began. These strategies have been supported and strengthen over the years, and have led to the success, the company enjoys today. To be successful in the airline industry you have to employ superior efficiency, quality, innovation and customer responsiveness.SIA has exercised a quality/service differentiation strategy to become one of the leaders in the passenger airline industry. ‘Singapore Airlines has carefully built a financial and fixed cost infrastructure which allows them to continue investing to support the brand while challenging the competition on costs’. (www. venturerepublic. com) More recently Singapore Airlines became a member with the star alliance, which helps the company maintain economies of scale by code sharing, wh ere SIA can offer services on another airline under its own flight codes and offer more destinations.By building solid capital the airline now enables them to purchase aircrafts and equipment internally without the need for leases and interest. This has enable SIA to have the latest aircrafts and renew them every 5 years. By having a new fleet the company is able to be more efficient with regards to fuel economy, maintenance, and have less downtime. (www. venturerepublic. com). Another benefit of owning aircrafts outright gives flexibility if there is a dramatic decline in the economy, SIA has the freedom of not being locked into long leases and aircrafts can be disposed of, if need be.Therefore they can handle the ups and downs of the economy, more so than competitors. (www. venturerepublic. com). Singapore Airlines have always concentrated on being innovative, as mentioned above they replace there airlines every 4-5 years taking advantage of new technology. The company has always the first to introduce new innovative ideas for example hot meals, free alcoholic and non-alcoholic drinks, Hot towels, personal entertainment systems, and video on demand. SIA will also be the first to own the new Airbus Super jumbo A-380 in 2006. www. allaboutbranding. com) SIA is committed to providing a world class quality and service, the airline allocates a substantial amount of time and money into there staff training and education. The company has 4 training facilities with various programs that exercise classroom, work experience and simulation strategies. (www. trainersdirect. com) SIA has more concentration on staff training than any other airline. Singapore Airlines employees have to complete a 4 month training course before they are even allowed to serve a customer.On average in 1997 Singapore Airlines spent $5600 per staff per year on training. The emphasis on staff training is so they can provide the best quality service. (www. trainersdirect. com) The branding of SIA is based on quality. SIA have the strongest brand name in the airline industry. â€Å"Singapore girl you’re a great way to fly† has been there brand of quality for the last 32 years. ‘The icon has become so strong that Madame Tussaud’s Museum in London started to display the Singapore Girl in 1994 as the first commercial figure ever’. (www. venturerepublic. com).The airline provides the best on flight cuisine including fine wines, and cocktails. Complimentary gifts are received on each level of passenger class. SIA have maintained a policy that once a passenger pays for there ticket there is no more to pay. (www. venturerepublic. com). Some airlines in tough economic times have started to charge for in-flight drinks and entertainment where SIA haven’t. This commitment to quality has won the airline numerous international awards and differentiated themselves from other airlines. Some issues facing Singapore AirlinesThe Airline has purchased a number of the new Airbus Super jumbo A-380, which could be a bit premature due to the fact they are still in negotiations with the Australian government over open skies. The Australian government holds the key to Singapore gaining open skies agreements, if an agreement is reached Singapore will be able expand and benefit from long haul flights between Australia and United States. On the flip side the introduction of the new airbuses into the industry will cause less demand on Singapore as a stop-over, refuelling hub.Airlines that adopt the new airbuses will be able to bypass previous stopovers and enjoy cost savings. As explained earlier there has been a dramatic increase in demand for inter-Asia flights. Rival players have noticed the increase in demand and have implemented there own low cost airlines. E. g. Australia’s Jet Star. Recommendations and Justifications Singapore Airlines conduct a very professional business they have a strong brand, strong human resources and ma nagement, advanced facilities and a proven track record as being one of the top airlines for the last 20 years. I recommend: The airline pursue â€Å"open skies† agreements to expand there destinations. †¢ Establish the long haul routes with the new Airbus technology before rival airlines purchase the aircrafts. †¢ Keep strong emphasis on the brand name and quality of service. †¢ Utilise some of the success factor from SIA on the new low-cost airline to compete with new rival competitors establishing themselves in the Asian market. †¢ Promote Changi Airports engineering and freight facilities to the new inter-Asian airlines as long haul flights maybe bypassing Singapore’s Changi Airport in the future. Stay with the competitive advantage outlined above, using the differentiation strategy. †¢ Maintain the innovation and complimentary products. †¢ Help support the Star Alliance to improve customer satisfaction. It is very hard to recommend a lot of strategies for Singapore airlines to undertake, as they have been leaders in the industry for so long and have developed award winning strategies that have made them very successful. This report has been constructed from a wide array of research that has complemented Singapore Airlines various approaches to conducting business.

securities and exchanges commission essays

securities and exchanges commission essays To: Securities and Exchange Commission From: Bryan Economic Analysis, Inc. Re: Report on Stock Prices of Internet Companies In Response to the SEC memorandum regarding the adoption of the policy of capping the stock prices of internet-related companies at 90% of their current value, Bryan Economic Analysis, Inc. has come to the following conclusions. Bryan Economic Analysis, Inc. agrees that if something is not done regarding the price of stock of internet-related companies, a drastic drop in the price of these stocks will eventually occur. This drop in the price of these stocks will have an incredibly adverse effect on the state of the US economy and the world stock market in general. The problem of this venture would be that capping of stock prices will result in temporary inefficiencies and a shortage in the market for stocks. However, the capping of stock prices is highly necessary to the future of the US economy. If the prices of these stocks continue to rise without check, the inevitable drop would cause the US to enter into an era of deep recession. The fate of the US economy depends on the capping of the stock prices of internet-related companies. If something were not done, the US economy and the worlds financial markets would experience devastating consequences. This report intends to show why it is necessary to put a cap on the price of stock of internet-related companies for the continuation of a prosperous economy, even though short-term inefficiencies will occur. If the SEC were to put a cap on the price of stock of internet-related companies, several things would occur. First of all, the price would be lowered by 10%, causing an increase in the quantity of stock demanded, because buyers are more willing to buy at the lower price. The demand cur ...

Analyzing Indirect Action In The Cherry Orchard And The Ghosts English Literature Essay Essays Analyzing Indirect Action In The Cherry Orchard And The Ghosts English Literature Essay Paper Analyzing Indirect Action In The Cherry Orchard And The Ghosts English Literature Essay Paper Actions or events do non needfully hold to be physically shown to the audiences because there are assortment of ways of ratting and portraying an image or an action that becomes the footing of a drama. Indirect action, which is neer seen on phase is that excess spice added by the dramatist to arouse the complications that are indispensable to foster a secret plan. It involves action of import to the secret plan happening off-stage. The audience does non see the action go oning in forepart of their eyes but they learn about it by watching characters stressing on the of import inside informations. Indirect action helps make tenseness, suspense and besides intensifies understanding of the secret plan for the reader. Anton Pavlovich Chekhov and Henrik Ibsen have both used indirect action to determine some of the most interesting scenes of the dramas The Cherry Orchard and Ghosts. In the gap act of Cherry Orchard, Anya s description of the rough status her female parent is in is an illustration of indirect action. This is apparent from Anya s statement when I arrived there were a batch of Gallic work forces with her and ladies, and an old Catholic priest with a book, and it was really uncomfortable and full of baccy fume I all of a sudden felt so regretful for mama, oh so regretful! [ 1 ]The girls nature of being cognizant and concerned is seen.Through the usage of ocular imagination the apprehension is made clear and the audience has been made to understand that Madame Ranevsky is running low on fiscal footings. Madame Ranevsky s character of being an dreamer is explored through the undermentioned lines and mama wo nt understand! We got out at a station to hold dinner, and she asks for all most expensive things and gives the servers a tip. [ 2 ]The girl s point of position is that the female parent is incognizant of the constitution being on the brink of b ankruptcy and wants to go on taking her epicurean life. The audience has been made cognizant of these cases even though it was nt acted on phase. The Cherry Orchard is the most of import symbol in the drama ; it is neer brought into the direct vision of the audience and is merely spoken approximately. The impact of the red grove on the different characters of the drama is really important in fostering the secret plan woven by Chekhov. In Act 1, Madame Ranevsky, the proprietor of the estate is reminded by Lopakhin that the estate will be auctioned in August to pay the mortgage of the estate. Lopakhin adds on by stating, but do nt you be uneasy my beloved lady ; sleep peace to the full ; there is a manner out of it. [ 3 ]It has become clear that the cherry grove is an built-in portion of Madame Ranevsky s life and it is a symbol of her young person and childhood. Chekov has expeditiously brought out the true nature of characters through their ain words, for case, when Anya says, there was person in the kitchen merely now stating that the cherry grove was sold today. Madame Ranevsky, Sold? Who to? Anya, he did nt state who to. [ 4 ]This action which was set off phase brings in forepart the consequence of the auction and reveals Madame Ranvesky s involvement in the ownership of the red grove. Lopakhin s address at the terminal of act 3, narrating the sale of red grove, is the most of import case of indirect acti on in the drama. Lopakhin: I bid nine thousand more than the mortgage and got it ; and now the cherry grove is mine! Mine! [ 5 ]Although the audience does non see the sale but is made cognizant about it merely through this indirect action around which the full drama is fused. Heavens alive merely think of it! The red grove is mine! State me that I am intoxicated: state me that I am of my caput: state me that it s all a dream! do nt express joy at me! I have bought the belongings where my male parent and gramps were slaves were they were nt even allowed into the kitchen. [ 6 ]Lopakhin shows his felicity after geting the cherry grove. Lopakhin s statement reveals the patterns of the clip when bondage was in pattern and the development of slaves that existed so. In this period of clip, a major population of helot in Russia was freed open uping a long anticipated societal alteration. Indirect action plays a critical function in this drama ; the memories of the yesteryear have resurfaced through the usage of indirect action. The characters are haunted by shades they are unable to command. The characters are invariably reminded about the memories of the yesteryear. Both captain Alving and Johanna are dead, yet both are responsible for blossoming the calamity. The relationship between different characters is vexing. In the gap act, the conversation between Mrs. Alving and Manders inside informations the relationship that existed between Mrs. Alving and captain Alving. When Oswald was born, I thought I saw a little betterment. But it did non last long. And after that I had to contend double hard-fight a despairing battle so that no 1 should cognize what kind of a adult male my kid s male parent was. [ 7 ]The battle Mrs. Alving is speaking about in the words quoted above, is the procedure which she practiced in order to white wash the repute forged by her hubby. Mrs. Alving in conversation with Manders references all past cases and reveals about all her experiences and agonies. Manders you have so had a pathetic experience. Manders. And this is the adult male you are constructing a commemoration to. [ 8 ]The commemoration which is being talked about is the orphanhood, an orphanhood which was built by Mrs. Alving to mend the harm that captain Alving had done to his repute. Subsequently on in the conversation [ from the dining room is heard the noise of a chair falling ; so Regina s voice is heard in a loud susurration: Oswald are you huffy? allow me travel! Mander s what s the affair? What is it Mrs. Alving? Ghosts. The twosome in the conservatory-over once more. ][ 9 ]The present state of affairs of off-stage action is compared to the old one where captain Alving was shown to be acquiring close to Johanna as Oswald is making now. Mrs. Alving presumes the shade of captain Alving is act uponing Oswald. Oswald I began to experience the most violent strivings in my head-mostly at the dorsum, I think. It was as if a tight set of Fe was pressing on me from my cervix upwards. [ 10 ]The hurting felt by Oswald is a consequence of his vermoulu disease which was inherited signifier his male parent and besides reveals that the wickednesss of the male parent are visited on the kids. Indirect action has helped in the patterned advance of the chief subject the past haunting the present . Regina: Mrs. Alving! Listen! They are shouting outside.Oswald: what can be the affair? Where does the blaze come from? Regina the orphanhood is on fire! [ 11 ]The combustion of the orphanhood is the most important illustration of indirect action. The orphanhood can be compared to the cherry grove which is the basis of the drama. The combustion of the orphanhood signifies that the characters can non be freed from the shade which they have to endure. Many cases of indirect action are explored in these plants of Chekhov and Ibsen. Whether it was sale of the red grove or the combustion of the orphanhood. They both are similar in demoing a alteration taking topographic point, every bit good as the patterned advance of clip. Towards the terminal of both plays the reader does recognize that what is non seen is best described through indirect action. Indirect action happens to be the most of import technique in order to come on the cardinal thoughts in both the plants.

Conflict Spectrum in Crime and Analysis Essay Example | Topics and Well Written Essays - 250 words

Conflict Spectrum in Crime and Analysis - Essay Example Prior to September 11, many undocumented workers did not have the correct validation, which creates a huge security burden in America. The Department of Defense has recognized this as a fact false or poor screened background checks were common, which made an easy avenue for terrorists to enter the country without proper validation. This new policy has been the hallmark of the new policy at 2015. This is undoubtedly a huge step up from the previous policies because policies dictate results when fighting crime and cybercrime as well. Secondly, Clark is calling for a mutual support when combatting crime and insists of a collaborative effort than cellos that are created within the organization. This has been prominent as the complexity of crimes has increased from previous years. Clark calls for a mesh network analysis in which agencies worked together to ensure that they are sharing information rather than chasing leads by

Thin film lab Essay Example | Topics and Well Written Essays - 1750 words - 1

Thin film lab - Essay Example Introduction: Evaporation is a physical vapor deposition process, which involves vaporization of material to be coated through thermo-mechanical treatments, transport of that material in vapor phase to the substrate surface, and consequent deposition on the surface of the substrate based on adhesion (Pulker, 1999). Evaporation is a very common technique for film deposition, which has been used since ages to coat glass, silicon and other substrates with coatings of a very wide range of materials. The most common technique used to characterize film growth for evaporation deposited films employs measurement of surface film resistivity, which depicts the behavior of formation of islands of nuclei of various sizes, followed by Ostwald Ripening, sintering and cluster migration, leading to continuous film growth (Ohring, 1992). Using these vastly used deposition and characterization techniques, we deposited and analyzed copper films. Theory: Evaporation deposition technique involves three e ssential steps (Thornton, 1988): 1. Evaporation of material to be coated to obtain vapors for deposition. 2. Transport of vapors to substrate for deposition. 3. Physisorption of vapors on substrate surface, leading to nucleation and film growth. Resistance heating is a method to carry out evaporation of the target material. This is done simply by using wires or plates of high resistance, which have high resistance heating in accordance with Joule’s Law (COMSOL, 1998-2011). Wires, filaments, boats, plates or other shapes of these heaters may be used in accordance with the shape of the element to be evaporated. Refractory metals such as tungsten, tantalum and others are used for this purpose. Sublimation furnaces, crucible sources or electron beam evaporators can also be used as the heating technique (Ohring, 1992). Vapor phase transport depends on mean free path of the gas used. Mean free path is the average distance that a molecule travels in a gas chamber between two consecu tive collisions (Weisstein, 1996-2007). Pressure is the main factor controlling the mean free path. Depending upon the pressure and mean free path, different pressure ranges are termed as low vacuum, medium vacuum, high vacuum or ultrahigh vacuum as shown below: Figure 1: Vacuum Ranges Shown with Pressure Ranges for Comparison. Illustration from Ohring, 1992. Surface preparation is an essential part of surface deposition processes, which include surface cleanliness, substrate preheating, plasma assistance with evaporation and other factors. All these factors and the processing parameters of the evaporation technique combine to produce the morphology, growth rate and microstructure of the deposited films (Thornton, 1978; Holland, 1956; Caswell, 1963). Experimental Method: As has been mentioned, surface cleaning plays an important role in the deposition. To make sure the substrate is not contaminated – which may lead to deposit contamination – we used gloves throughout t he handling process. The four glass slides were agitated in a vibration tank to loosen contaminants, cleaned with alcohol, followed by blow drying of the cleansed slides with argon. These glass slides were then placed in marked containers. The evaporator preparation consisted of the following steps: 1. Tungsten wire was wound to form a filament. 2. Copper pieces, which were to be evaporated later, were placed on the tungsten filament at three places. 3. Glass slides were placed in premade stencils to ensure
