Microsoft Word Microsoft Access Microsoft Internet Explorer 6 Paint Input An input device is that hardware which allows you to put data into the computer. The main input devices I have used are keyboard, mouse and scanner. Device Speed Errors that can be made Way to correct errors Keyboard The keyboard does not have a set amount of speed it all depends how fast the typist is typing. The speed is calculated in Words Per Minute (WPM). The errors which can be made are that you can type in a word by mistake or do spelling mistakes. If you have typed a word wrong then you have to press back space or if it is a spelling mistake then put the spell check on which underlines the mistake in red. It then gives you a list of words to correct to. Mouse The speed of the mouse actually depends on how fast you move the mouse. You may click on icon which you did not want to press. You have to press back or if t has opened an application then exit it. Scanner The speed of the scanner depends on how powerful the scanner is. The more powerful the faster. Latest models will have more power. You might want to see what goes on in scanner and will lift the lid up. You have to wait till the scanning finishes then you have to repeat it all over again. Keyboard The way I detected my errors is that I checked my work twice. The way I corrected my errors is that I clicked the underlined words and chose a suitable word from the list. Spelling mistakes are underlined in red like this and grammatical mistakes are underlined in green like this. If there was none suitable then I would re-type the correct word. Thereafter I gave it to friend for proof reading. Mouse The way I detected the errors is that when I went on an unwanted page. The way I corrected it is that I simply went back. To prevent such errors; I done my work slowly. If I was on the internet and I made a mistake then I would click the button called BACK which is on the top left corner. Scanner After the image was been scanned, I checked if there were any mistakes in the digital image. If there were any then I restarted the scanning. The way I prevented these errors was that before scanning I made sure that the page was the right way round and having no creases on the paper. Effects of Inaccurate Data Inaccurate data will affect the system by mainly consuming time and causing problems for customers. Data Effect Way it can be prevented Name spelt incorrectly If the name is spelt incorrectly then when the tickets reach the person and the name does not match the name on the passport then the person can not go abroad. The way it can be prevented is that tell the customer to repeat it twice. Also tell the customer to say it in phonetics. And lastly, confirm before putting the phone down. Address not correct, such as postcode If the address or the postcode is not correct then letters may not reach the person and go elsewhere. The way it can be prevented is that tell the customer to repeat it twice. Also confirm before putting the phone down. For the postcode I shall also keep an input mask which is LL0\ 0LL. Recommendations not checked correctly If the recommendation is not checked correctly then customers may not get the offers which they have the right to get. The way it can be prevented is that make sure that the recommendation is there and recheck it at a later stage. Gender not entered correctly If the gender is not entered correctly then a staff could put a customer to shame if it is said wrong over the phone. The way it can be prevented is that tell the customer to repeat it twice. Also confirm before putting the phone down. Also I will make sure that nothing other than male or female is entered into the gender. I will do this by entering a validation rule and validation text. This means that every time something is typed wrong in that field than it will not be valid and then a message will come up say what to do. Date of birth not entered in correct format If the date of birth of birth is not entered in the correct format then part of the database could go wrong and it would also cause problems to the customers if it is in the wrong format on tickets and letters. The way it can be prevented is that keep a strict format that all the staff could stick to. Also recheck if it is entered according to the format. And if talking to the customer over the phone then ask which format it is. For example; DD/MM/YY or MM/DD/YY or YY/DD/MM. I have also thought of having a set format for the date of birth. To maintain this I shall have an input mask which is 00/00/0000;0;; Subscriptions not entered in correct format If the subscription is not entered in the correct format then the subscription could go on and on for ever if the expiry date is not entered correctly. The way it can be prevented is that recheck if the date is there and it is entered correctly with the correct format. For this also I will have a set format and to maintain this I will an input mask which is 00/00/0000; 0;; I think that the overall best method of checking the accuracy of the data is that it is rechecked and confirmed. Also I would prefer having an input mask where possible in places like date of birth and post code. Validation It is very important that you have correct and accurate data or else this could lead to many major problems. Validation is a very good way to ensure that you have the correct data. Validation is when the computer itself automatically checks the work and makes sure that the data entered is reasonable but it does not check the accuracy. The main aim of validation is that it makes sure that the data entered is reasonable, allowable and sensible. For example; if you typed in the date of birth of a secondary school student then it is likely to be between 1988 and 1995. If 1955 was entered then it would definitely be wrong and the computer will not accept. This is making sure that the data is reasonable. If Sams date of birth is 1992 and 1989 was typed then it will be still accepted but the data is not true. This is not checking the accuracy of the data. The following are a few methods of validation: 1. Presence check This checks that data has been entered into a field. An example of this method is; * In most databases a key field can not be left empty. 2. Check digit The last one or two digits in a code are used to check if all the other digits are correct. An example of this method is; Â  In shops and super markets, barcode readers use check digits. 3. Type check This checks that of a certain type is entered into a field. An example of this method is; In a clothes shop, dress sizes may range from 8 to 18. For this type of data, a number data type would be suitable. If the data type is set as number then only numbers could be entered and a person will be prevented form typing in letters and words. If size ten or eleven was entered, then it would be rejected and 10 or 11 would need to be entered. 4. Format check This checks if data is in the correct format. An example of this method is; Â  A National Insurance number is in the form LL 99 99 99 L. In which L is any letter and9 is any number. 5. Spell check This looks up words in a dictionary. An example of this method is; Â  When word processing. 6. Length check This checks that the data entered is not too long or too short. An example of this method is; A password which needs to be six characters long. 7. Range check This checks that a value fall within the specified range. An example of this method is; Number of hours worked must be no more than 50 hours and more than 0 hours. 8. Look up table This looks up acceptable values in a table. An example of this method is; Â  There are only seven possible days in a week. Verification Verification is to check if the data meets the required standards. For example; if a password is created, then you have to verify by typing it a second time to see if they both match. If the passwords did not match each other then the computer does not allow him to go through because the required standard is that the passwords must match each other and must be typed in correctly. The following are a few methods of verification: 1. Re-typing the data Re-typing the data could get rid of a lot of mistakes. This method is only ideal for small amounts of data such as passwords. However, also in small amounts of data there is also a problem which is that the mistake could be repeated in the second piece of data and this does not pick up the mistake. The reason why it is not ideal for large amounts of data is for three main reasons. They are as follows; You would end up with two copies of the data Mistakes which are repeated will not get picked up. Â  It would be time consuming to re-type large amounts of data. 2. Checking the data on the screen with the original paper document This method saves having to re-type the data. It can help where in data has been transposed or entered incorrectly. However, it is not easy and can get tough trying to move your eyes back and forth paper copy and monitor. 3. Printing out a copy of the data and then comparing it with the original copy. This is probably the easiest method because you bath copies side by side and you can check for mistakes. However, this method can also become time consuming if large amounts of data have to be checked. Also if you go too quick the mistakes could be left. Output Output device allow you to view information after it has been processed. Device Type The way it works Advantages Disadvantages Best place to use it Printer Laser In laser printers powdered ink is fused on to paper by heat and pressure. They use toners instead of cartridges. They produce a very high quality of output. Laser printers are very expensive to buy. The best place to us it is in a library or any study area because they are very quiet and fast. Laser printers are very quiet and do not disturb. Toners are used instead of cartridges this means that there may be extra costs. Hundreds of pages could be printed within an hour. They are very huge so if there are any breakdowns then repairs could be very costly. Inkjet Inkjet printers work by heating ink as it flows through small nozzles. It then creates a dot on the paper and keeps happening until a picture forms. Ink is stored in cartridges. It is quite fast but not faster than Laser printers. The quality of colour printing is very low. The best place to use it is in your house because it is cheap and it is worth the price. Print outs are very neat compared to other print outs. Print out may come out wet and this may smudge. Nozzles are much cheaper than toners. Inkjet printers are very noisy. Dot-matrix Dot-matrix printers work by using a set of steel pins which strike an inked ribbon onto paper producing a sequence of dots. Dot-matrix printers are cheap to buy. They are very noisy and disturbing. The best place to use it would be something like a factory because they make a lot of noise and in a factory printers are used very less. It is very cheap to operate. They are very slow and take ages. They are not very hard to use. You can not make colour copies. Monitor TFT Thousands of tiny dots called pixels are displayed which then create an image. TFT monitors are very slim and take up less space. TFT monitors are very slim and can easily get knocked over. The best place to use a TFT monitor would be in an office or an ICT room because It would be less stuffy and more nice and comfortable to use. They create very less heat in the room. They can produce dull and low quality images if the monitor is not good. TFT monitors are not made of glass so the screen will not break. The screen can be damaged if it is poked many times. CRT Thousands of tiny dots called pixels are displayed which then create an image. CRT monitors are big and hard to get knocked over. They create a lot of heat and it can get very stuffy in the room. The best place to use a CRT monitor would be in a nursery where there are lots of small children and the chances of getting damaged are very high as the children will be running about. CRT monitors They are very cheap. They take up too much space and they are less stylish. They are hard to be stolen because they are massive. CRT monitors can make a lot of noise. After looking at all the different types of input devices, my work has been affected greatly. I have also tried my best to use the best out of all the output devices in my task. Conclusion Most of the components and other things I used for my tasks were very suitable. For example, a CRT monitor can not be used in an office and a TFT would be the best.

Gang Violence and Biker Gangs :: essays research papers

Gang violence is a major problem in our society today. Gang violence could take place in our neighborhoods and corrupt the young children easily influenced by the violent behavior as well. In the two poems, ?Leather-Jackets, Bikes and Birds? by Robert Davies and ?Street Gang? by H. Webster, the two poets write about gang related issues discussing the ill-mannered bikers who cause these problems to other around them. These poems discuss the violence, death and illegal activity in which a number of people participated in, which like reality is the problematic truth. Both poems are similar because their main intention is gang related violence issues in society today and the distinctive character of the darker side in human nature which causes the harmful consequences of a corrupt humanity. The communication strategies used by both poets are able to grasp the reader?s interest due to the fact that both poems have similar methods of word selection which is diction and are able to describe the psychological minds of aggressive behavior. The poem ?Leather-Jackets, Bikes and Birds? has sentences that describe the type of characteristics gang members have and illustrate their overall presence around others. For example when the poet writes, ?pretending they are looking for trouble demonstrates that the individuals of a gang gather not to enjoy themselves but to cause excitement among themselves for the wrong reasons. Another quote from the poem that describes the psychological mind of gang members is ?because you?ve got to be hard to be a leather-jacket this quote shows that gang members have a mind set that they must be tough, strong and overall powerful to gain their respect. Similarly, the poem ?Street Gang? the description of violence used and the defeat against law is well detailed by the actions caused by aggressive behavior. For example when the poet writes ?the law overthrown describes that the street gang members do not consider the law at hand and make a choic e based on their psychological mind structure and use forceful actions upon their victims. Furthermore, literary devices such as imaginary, alliteration, repetition, oxymoron, onomatopoeia, simile and parallel structure used in both poems displayed a greater understanding towards poetry and defined both as comparable poems. The poems ?Leather-Jackets, Bikes and Birds? and ?Street Gang? are not in rhyme and I believe both poets have formed the poems without rhyme because the tone of seriousness towards this issue was to be brought out to the reader?

Case Study Problems Perrier Essay

1. Identify the key elements of the resistance to change described in this situation. To identify the key elements of the resistanceto change described in this situation, one may make use of the six Change Approaches of Kotter and Schlesinger.[1]The model prevents, minimizes or descreases resistance to change in organizations. According to Kotter and Schlesinger (1979), there are four reasons that why people resist change, three of which are applicable to this case: The Parochial self-interest occurs when people are concerned with the impact of the change on themselves and how it may affect their own interests, rather than considering the effects for the success of the business. The union suggests this of Nestles. Jean-Paul Franc, head of the CGT at Perrier, sees the situation differently. In regard to the company’s plan to cut 15 percent of its workforce he protests: â€Å"Nestle can’t do whatever it likes† He says, â€Å"There are men and women who work here†¦ Morally speaking the water and the gas stored below this ground belong to the whole region.† [2] Misunderstanding which evolves through communication problems or inadequate information. Management of a company could not agree to a decision, perhaps due to a lack of information of the real problem. Relating to this case it is not very clear what is causing the lower production at this plant. According to Nestle CEO Peter Brabeck-Letmathe, â€Å"We have come to the point where the development of the Perrier brand is endangered by the stubbornness of the CGT. Where else according to Jean-Paul Franc, head of the CGT at Perrier as mentioned before, â€Å"In regard to the company’s plan to cut 15 percent of its workforce he protests, â€Å"Nestle can’t do whatever it likes.? He says, â€Å"There are men and women who work here†¦ Morally speaking the water and the gas stored below this ground belong to the whole region.†[3] Different assessments of the situation occurs when employees disagrees on the reasons why the company has to change and on the advantages and disadvantages of the process of change. This applies to the above differences in assessment of the problem and solution by the Nestler’s CEO and the union head. 2. Construct a change management strategy for dealing with this situation. In so doing, identify what approach (es) to managing resistance you recommend and provide a clear justification for your choice. Kotter and Schlesinger set out six change approaches to deal with resistance to change. In the following we make use of four of the approaches: [4] 1. Education and Communication There is a lack of information or inaccurate information and analysis. Instead of discussing directly with the employees, that sales were dropping, the manager used a form of manipulation in form of placing the competition’s bottles water e.g. Badoit Rouge in the factory cafeteria, which further antagonized workers. This action was opposed to the intended motivation. One of the best ways to overcome resistance to change is to educate people about the change effort before change occurs. Up-front communication helps employees to see the change effort. This reduces incorrect rumors concerning the effects of change in the organization. 2. Participation and Involvement This approach is useful when that the initiators do not have all the information they need to design the change and where others have considerable power to resist. This is the case at Perrier, where an identification of the real problem is essential. When using this approach it allows including the employees in the problem definition as well as potential solutions. It encourages open communication. The union and Nestles need to set the same goals. When employees are involved in the change effort, they are more likely agree with the change rather than resist. This approach is likely to lower resistance and those who merely acquiesce to change. 3. Negotiation and Agreement Someone or some group may lose out in a change and where that individual or group has considerable power to resist. This would be effective in dealing with the union at Perrier. This can be done by allowing change resistors to veto elements of change that are threatening. Another way is that change resistors can be offered incentives to leave the company through early buyouts or retirements in order to avoid having to experience the change effort. This approach is appropriate where those resisting change are in a position of power, like the CGT. 4. Explicit and Implicit Coercion This is a last resort approach where speed in change is essential. Managers can explicitly or implicitly force employees into accepting change by making clear that resisting changing can lead to losing jobs, firing, transferring or not promoting employees. Working together with CGT, Nestles can negotiate a projected percentage of increased production or otherwise the suggested number of layoffs (15%) will be required.

When Night Falls in Elie Wiesels Book, Night - 687 Words

When Night Falls Elie Wiesel’s book Night presents certain aspects of Jewish history, culture and practice through the story of Wiesel’s experience with his father in the concentration camps. Wiesel witnessed many horribly tragic things throughout his days in the concentration camps. It is these experiences that cause him to struggle with his faith. He grew up as a devote Jew who enjoyed studying and devoting himself to his religion. Throughout the book we see him struggle with his concept of faith and beliefs. For example the quote â€Å"†¦there was no longer any reason for me to fast. I no longer accepted God’s silence. As I swallowed my ration of soup, I turned that act into a symbol of rebellion, of protest against Him† (Wiesel 69). We can see his frustration with God and how hurt he is by what is going on around him. However we also see him wanting to hold on to some hope that things will get better and that God is real. We can see his hope in his encounters with the other people at the concentration camps as well as in the things he says. For instance he says †in spite of myself, a prayer formed inside me, a prayer to this God in whom I no longer believed† (Wiesel 91). It is like this battle between his brain and his heart. His brain is seeing all these horrible things going on around him and wants nothing to do with God or faith anymore but his heart still believes in it all. It still has hope and love for something that he can no longer see around him.
