Management of Information Systems Unit 7 Project Essay

Management of Information Systems Unit 7 Project - Essay Example Since accounts are kept private for the customers via the use of a password, customers generally feel safe and secure knowing that only they can see this information. This approach is certainly less of an invasion of privacy simply because it does not require the customer to do any extra work. Surveys and questionnaires require an extra amount of work, and also are often ignored by customers because they feel that it is a violation of their privacy. Furthermore, if the surveys are emailed to the customer, their opinion of the survey may be even worse and lessen their opinion of the company overall, since they may view this as Spam. Therefore, using information that customers are already willing to provide to get what they want through the orders they make reveals that customers are willing already to disclose this type of information in order to get what they want. Furthermore, most customers feel just fine disclosing this information because the account setups are private. This, the refore, makes the information feel much more private than a publically Emailed survey or questionnaire. A decision support system that I recently used was actually using Amazon.com to find other books and information related to my previous orders and searches. Since I am an avid reader and enjoy history, I was trying to find more books relating to particular time periods I had already ordered and read about. Therefore, I was able to use the information I had provided to Amazon in the past to have them provide me a selection of possible books that I might be interested in, and might otherwise have overlooked. I felt that the results were accurate. For the most part, I was presented with results that reflected upon the same time period I wished to read more about, and a variety of authors. I was therefore able to find the information I needed to find. I find the whole experience very satisfying, as the search method was accurate enough to provide me with what I needed. Prepare a one-page report on the career you intend to pursue. Give at least four examples of activities involved in such a career that call for problem solving. Explain which problem solving is structured and which is unstructured.I intend to pursue a career in computer literacy and information technology. In this career field, I will need to have the necessary problem solving skills in order to understand exactly what people need, for instance, when certain items are not working for them on their computers. This will require me to be able to problem solve and trouble shoot for a wide variety of computer technical problems. Furthermore, within this problem solving sphere, I will also need the necessary problem solving skills in order to know how to approach these individuals with appropriate answers to their questions. This means also that I must know how to break down the information well enough to explain to people what went wrong so that they can hopefully avoid it in the future, and/or fix the problem on their own. Furthermore, I will need to know how to assist people both on a face to face level, as well as over the phone. All of this will require me to formulate a structured approach to problem solving. This is because all of the issues I will be running

Writing the Research Paper Essay Example for Free

Writing the Research Paper Essay 1. Identify the subject of your peer’s research paper? The research paper was an exposà © on the activities of hackers in gaining unauthorised access to the internet and the government action to deter them. Explain why the subject is too broad, too narrow, or appropriate for the length of the paper. The subject is too broad for this kind of paper because the paper was not able to touch on the fine details that would have made the subject more explicit to people who are not conversant with the computer. The writer made mention of a lot of terminologies that could have been explained if the paper had been longer. 2. The thesis statement is: stopping hackers from causing more harvoc. The sentence that, in my opinion, expresses this is : â€Å"Wi-Fi and ceasing the hackers endeavours† 3. I have singled out this paragraph: â€Å"Protection against wireless hacking is extremely difficult to keep secure. There are products developed that require no configuration of any firmware or upgrades of any kind. Wave Security has developed this software. The software is used to detect any threats and secure the system. WaveSentinel handles intrusion detection, monitoring and logging for standard access points. WaveScanner integrates with the existing TCP/IP security scanners to reveal specific wireless vulneratbilities.† It is quite explicit as it attempted to find the solution to the nagging problem of illegally connecting to the internet via other people’s wireless connection. This paragraph is easy to comprehend and any reader would be eager to know more about this solution as it was presented as a very simple and attractive solution. 4â€Å"In all the precautions and security factors with Wi-Fi I have found it seems wardriving is still quite popular and hidden from most internet users knowledge. `Chances are that a WarDriver hacking a bank may get away with it, leaving the Wi-Fi owner the suspect. Thousands of clueless people, including those in tony apartments with wireless internet, have leaky networks-allowing anyone on the road easy access to the Web’ â€Å" 5. Paragraphs a. That need to be supported with more specific details. â€Å"This free wifi will reduce the hacker’s urge to steal and feel like the hacker did any monetary damage to you† â€Å"In all the precautions and security factors with Wi-Fi I have found it seems wardriving is still quite popular and hidden from most internet users knowledge† b. That contain any logical fallacies/faulty reasoning. Recommend strategies to improve the effectiveness of those paragraphs. I found these statements illogical to say the least. It seem as if the native language of the writer is not English language, or better still, the writer has not mastered the basic rules governing the use of the language. There are actually better ways of constructing these sentences that would be both simpler and more explicit. I hereby suggest the following amendments to the statements. Since the beginnings of computers capable of accessing wifi  Ã¢â‚¬Å"from the time computers have been able to accessing the internet using the Wireless Fidelity (WIFi) technology  hackers have had their enjoyment in war driving  Ã¢â‚¬Å" in the times past, hackers have had a swell time enjoying War Diving†Ã‚  Data encryption needs to become harder for hackers to figure out  Ã¢â‚¬Å"The technology of Data Encryption needs to be more sophisticated in order to deter intending and potential hackers from carrying out their heinous act†Ã‚  Protection against wireless hacking is extremely difficult to keep secure  Ã¢â‚¬Å" Security against illegal intrusion is not an easy task to achieve† 6. Identify places in the paper where the author fails to maintain an objective point of view. What steps would you recommend to the author to correct the problem? Throughout the paper, the writer made use of references to support his claims. He however lifted these phrases and the result is that they all did not blend with his own words, the tone was different. 7. Check the writer’s sources and documentation format for both in-text citations and the References page to ensure that they conform to APA requirements. Identify any errors that need to be corrected in the final draft. 8. Identify any missing elements for the essay (title, abstract, thesis statement, and support for claims, in-text citations, conclusion, or reference list). The title, abstract, thesis statement, in-text citations and conclusion were all included in the paper. 9. Identify any unity or coherence issues that you find. 10. Identify any areas where more effective use of transitional words and phrases would improve the coherence of the essay. In the body of the essay, the writer made use of several sources without regard for the tone of the words. Most of these references, however helpful they are, still ended up jumbling up the whole paper as the whole thing were distorted. 11. Additional Comments: The paper is very informative and it contained a lot of facts. However, the writer failed to sieve this facts to being out what could have been a more coherent paper. Most of the references contained information that enriched the paper. However, they all had different tones both formal and informal. The result is a collection of paragraphs that I can describe as disjointed. Coherence was lacking throughout.

Determining Concentrations with Spectrophotometer

Determining Concentrations with Spectrophotometer To learn how to make a spectrophotometer accurately and interpret the data recorded to construct a graph and obtain a standard curve using excel. To learn how mathematical calculations of the absorbance readings and of unknowns to get the standard curve of a concentration value from the curve. Method: Refer to Proc 2048 Biochemical Engineering Lab Manual Exercise 1- The Spectrophotometer Absorbance readings of Methyl Orange and Bormophenol Blue were recorded for a range of wavelengths from 400 to 700nm intervals, zeroing the apparatus with a distilled water blank after each change in wavelength. Exercise 2: Determination of Glucose Concentration Each of the standard glucose solutions and the unknown solutions were tested in spectrophotometer using a wavelength of 580nm and absorbance readings were taken for each. Exercise 3- Determination of Yeast concentration Similarly to the glucose experiment absorbance readings of different standard and unknown yeast concentrations were recorded at a wavelength of 600nm. Unknown solutions U and V were also diluted to a 1:2 ratio with distilled water as the concentrations are too high and fall outside the acceptable absorbance range. Calculations: Unknown glucose calculations y = 0.1836x 0.008, Solve for x gives Subbing in absorbance values for each unknown glucose solution gives: Unknown yeast calculations y = 0.557x + 0.003 Solve for x gives Subbing in absorbance values for each unknown glucose solution gives: U and V need to be multiplied by 2 after calculation as they were diluted in a 1:2 dilution Discussion: In exercise 1 different wavelengths was used and the absorbance in the graph increasing then decreases and then slightly increasing. The colour contributes to where the max absorbance occurs and the concentration affects the intensity of the peaks. For instant the parts blue and the parts yellow light is a green colour. This is the light that we see, and therefore the wavelengths of light to pass through the absorbance with the minimum in terms of all other waves of light absorbance higher. Spectrum analysis of pure sugar solution would be impossible for any absorbance that can happen is the solution to be transparent and any suspended particles. This means that solutions need glucose to the reaction with 1 ml of 3.5 acid Dinitrosalicylic (Domain Name System) to form amino 3, 5 Nitrosalicylic acid, a compound color absorbs light strongly in all parts of 580nm. This enables us to use spectral analysis to determine the focus. This applies only if the intensity of the color of the product is directly proportional to the concentration of the reactants. In this case, glucose concentration is directly proportional to the amount of amino 3, 5 Nitrosalicylic acid producers such as the Stoichiometry of the reaction is 1:01, and most of this focus is not to reach a balance It is important that the blank or zero concentration used for this experiment is not just distilled water but 1ml of DNS and distilled water made up to the same volume as the other samples, as the unreacted DNS in our glucose solutions is contributing to the colour of the solution as well as the 3-Amino,5-Nitrosalicylic Acid. In exercises 3 yeast is basic in terms of chemistry is based on the physics. By increasing the concentration, the absorbance will increases in yeasts solutions however they are not coloured but they are block and scatter, so some the light will not go through them. And this because we are dealing with suspended particulate matter, and not resolved ions. Blot out the light commensurate with the focus so that we can find the concentrations of unknown values of absorbance. It is important to shake well before taking the sample absorbance reading such as yeast, particles and settle to the bottom, that mean if we are not shaken them, so they will give us a lower absorbance reading. Questions Exercise 2 The cuvettes have different surfaces for two reasons. The frosted ridged sides are so no light escapes out the sides of the cuvette giving a false reading. The other reason they have 2 different sides is so that you dont handle the transparent sides directly as oils or dirt from your fingers could increase the absorbance and give inaccurate results Particles in solution (just like in the yeast experiment) affect the absorption reading by blocking or deflecting light away from the detector therefore the particles in a coloured would increase the absorbance and give inaccurate results, unless the concentration and size of the particles is constant with all tests conducted then it would not affect the calculated results. A standard curve in spectrophotometric analysis is a linear trendline that fits through your experimental data. It is calculated by measuring absorbance readings at a range of different concentrations and plotting them against each other. A linear regression done my excel or other means is calculated for the points and an equation in terms of absorbance (Y) and concentration (X) is formed and you can use this equation to calculate unknown concentrations from absorbance readings. Exercise 3 The cuvettes have different surfaces for two reasons. The frosted ridged sides are so no light escapes out the sides of the cuvette giving a false reading. The other reason they have 2 different sides is so that you dont handle the transparent sides directly as oils or dirt from your fingers could increase the absorbance and give inaccurate results Firstly dilute the dye to an adequate concentration with distilled water .Find the maximum absorbance of the diluted dye by testing absorbances at a range of different wavelengths ensuring you zero with distilled between each wavelength. Take some of the dye and dilute it with distilled water to about 6 8 different concentrations i.e. 1:100 à ¯Ã†â€™Ã‚   1:10, depending on what absorbance readings you get adjust the dilutions to fit in a range of 0 à ¯Ã†â€™Ã‚   0.8 as that is where the Beer-Lambert Law applies. Using the max absorption wavelength you would then prepare a standard curve for the dye by measuring absorbance of each of the diluted concentrations. Plot the absorbance vs concentration and use a linear regression to form an equation. Take a sample of the waste water and filter off any suspended particles to increase the accuracy of the absorbance reading. Finally measure the absorbance of the sample diluting accordingly if absorbance is not in the required range. Using th is absorbance value in your standard curve equation calculate the concentration and multiply by your dilution factor if the sample was diluted. Assuming you already have a standard curve and equation for the nitrate complex for a range of 0 à ¯Ã†â€™Ã‚   1.5 mg/L. All you need to do is dilute your sample from your suspected 55 mg/L to fall in the concentration range of 0 à ¯Ã†â€™Ã‚   1.5 mg/L. So a 1:50 or a 1:100 dilution would be enough to give you 1.1 mg/L or 0.55 mg/L respectively. Then the sample is ready for spectrophotometer analysis. Conclusion: All of the yeast and sugar were obtaining accurate test results with the value of R2 (0.99) for each of the trend lines and graphs. 99% accuracy meaning that lines fits for most the points. The process was a good knowledge to learn and it is useful to understand the Beer-Lambert law and his applications.

My Life Long Friends :: Friendship Essay

My Life Long Friends      Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Looking around my living room, I see my greatest friends of my life are all around me on my book shelves.   Every book I lift off the shelf pinpoints a time in my life.   They represent all the joy, sorrow, and laughter felt in my life.  Ã‚   The large, shiny red poetry book my father read to me reminds me of all of these.   It is probably my favorite.   Then I recall my people friends that attended school with me through the years.   What great fun they were!   I doubt I'll ever forget the smell of my kindergarten class and my first meeting with Belle Hudson.   As I get older, I realize how precious that friendship was.     It taught me how to be a friend and what I have seen in her is what I have looked for in friends ever since.   Now as an adult, I see Belle in friends like Tiffany, Rachelle and it seems my favorite characters in my books have always reminded me a bit of Belle.   Belle had a profound effect on me in childhood as well as later on in life.   She was my finest friend throughout grammar and Junior High school.   We fancied relishing our lunches together.   Laughing about the boys' wicked ways and planning our revenge   at the ensuing recess.   This always made lunch go by so swiftly.   It was hard to tear us apart.   Hell, it was hard to tell us apart.   We were both round bodied and a bit out of shape. But I always saw Belle in a jovial light.   She had a merry way about her, and her laugh was infectious; it reminded me if Christmas bells, tingly, jingling and warm.   I miss her.   She was happy, giving and warm.   Upon reflection, these are the attributes I look for in friends.      Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Rachelle holds a special place in my heart.   I work with her and have found her to be a superb listener and always seems to know how to dole out the right advice. It seems no issue is too large to solve, and I would love to duplicate her upbeat nature   in me. It was our mutual interest in books, not our hiring at the same company that   brought us together.   She desperately wants to be a great writer.   I know she will be.  Ã‚   As our friendship deepens, she has helped me realize my own potential.   Although younger than I, Rachelle has lived a much tougher life.   I could say I know this as hear her words of

Miser to Man of the city in a Christmas Carol Essay

Scrooge is not very well like by the Cratchit’s. You can see this by â€Å"I wish I had him here. I’d give him a piece of my mind to feast upon and I hope he’d have a good appetite for it†. This shows that he is not liked because â€Å"he is an odious, stingy, hard, unfeeling man†. This make Scrooge feel bad and he learns a valuable lesson. Treat others as you wish to be treated. If he doesn’t want to be called bad tempered, money grabbing, old sinner, then we has to be caring and thoughtful. Scrooge every year at his nephew Fred’s house, is invited to a Christmas party, but always turns it down. Scrooge is not very well liked by the people at the party especially Fred. You can tell this by they invent a new game called â€Å"yes or no†. This shows that Scrooge is talked behind this back and that people do not care if they hurt his feeling. Scrooge feels unwanted and uncared for. You can tell this by â€Å"One half hour, Spirit, only one†. This shows that Scrooge has feeling and he wants to go as soon as possible because he crying and in great disbelief. Scrooge’s future looks uncertain when he goes into the future and sees him in a corner of the graveyard, unnoticed, uncared for. You can from this point that Scrooge is at the end of his tether. You can tell this by â€Å"For the first time his hand appeared to shake†. This shows that Scrooge has become more and more frightened and knows he must change his future to be cared for and missed dearly. He does not breakdown till this point because he can not change the past and that does not bother him. At the end of all the spirits visiting Scrooge is disappointed himself by being a selfish, lonely, old man. The Last straw is when he visits his own grave. He is already depressed with the entire trauma and another dig in his grave has made him tremble in fear. You can tell this by â€Å"The Spirit stood among the graves, and pointed down to one. He advanced towards it trembling†. This shows that Scrooge is scared of him and wants to change rather than just a person who has just died. Scrooge really wants to change because he doesn’t want to be the man in the corner that no one visits. You can tell this by â€Å"Are these the shadows of the things that will be, or are they the shadows of the things that may be, only†. This shows that Scrooge wants to change because of his experiences over the night. He wants to know that if he changes and mingles with people he will not die and nobody will care. He gets more and more distressed because the spirit won’t tell him if he can change his shadows of the future. You can tell this by â€Å"Assure me that I yet may change these shadows you have shown me, by an altered life†. He is on his knees, desperately trying to change his future. This tells us from this point onwards Scrooge will be a changed man to avoid distressing death. Scrooge wakes up the next morning a changed man, a generous man. You can tell this by â€Å"Scrooge regarded everyone with a delighted smile†. This shows that Scrooge has took into great account of what the spirits said and gone out to change his future. He is a changed man to the public. You can tell this by â€Å"If you please, ‘said Scrooge and not a farthing less. A great many back-payments are included in it, I assure you† This shows Scrooge as being as kind, thoughtful, caring man rather than a â€Å"squeezing, wrenching, grasping, scraping, clutching covetous old sinner†. Scrooge now respects the poor people more than ever, especially the Cratchit’s. You can tell this by â€Å"and therefore I am about to raise your salary†. This shows that Scrooge would rather share more of his money to make more people happy than just himself. This is different from the beginning because when the gentleman comes to visit he pushes him away and believes in â€Å"Laissez Faire†. Scrooge has now become a happier and more cheerful human being because he has changed his way of living. You can tell this by â€Å"they all sit around the table eating Christmas dinner†. This shows he is not self-contained, lonely old sinner, but a sociable character and because he changed his actions, Tiny Tim did live and Scrooge and his family say â€Å"God bless Us, Everyone! â€Å"

Crucible essay Essay

The Crucible takes place in Salem Massachusetts during 1692. It takes place during the tragic time of the so called Salem witch hunts when many innocent people were accused of being a witch or dealing with the devil. As a result of these convictions many people confessed to save their lives, others who would not confess to a lie were hung or executed by other methods such as being pressed. The play the Crucible was wrote by Arthur Miller during the â€Å"Red Scare†, which was almost parallel with the Salem witch hunts in that many innocent people were accused of actions of communism and espionage that they did not take part in. The Crucible is not so much about a witch hunt as it is an illumination of human weakness, hypocrisy, and vindictiveness. In the Crucible there is quite a bit of human weakness. This can easily be seen through all of the people in the story who admitted to being a witch or dealing with the devil instead of being strong and denying the fact that were not a witch and be put to death. When this all begins, Abigail, the reverends own niece, blames Tituba, the reverends slave from Barbados of being a witch. When she is accused on page 847 she first denies it, â€Å"I don’t compact with no devil,† later on after Mr. Putnam says â€Å"this woman must be hanged†, Tituba gives into her natural human weakness and cries out â€Å"†¦ I tell him I don’t desire to work for him(the devil) sir.† That is just one of the many cases where human weakness is illuminated in the play, it is also the most common, many people gave in to the pressure so they wouldn’t be hung. Another way human weakness was illuminated in the Crucible is that John Proctor will not admit his affair with Abigail because he is afraid he will lose his farm and ruin his name. Mary Warren also gives into human weakness when John Proctor asks her to go to the court and tell that the girls are all faking there so called sickness caused by the accused witches. When she tries to tell Judge Danforth Abigail interferes and Mary pretends to go crazy again. Amongst all the human weakness there was a lot of hypocrisy mostly amongst the people who seemed strong and pure. The Crucible may take place during the Salem witch trials of 1692, however the illumination of weakness, hypocrisy, and vindictiveness are what the  play is actually about. Just like what was going on during the Red Scare during Arthur Miller’s time.
