INFORMATION MANAGEMENT
COURSEWORK REPORT COURSE: INFORMATION MANAGEMENT COURSEWORK ID: CIT-3-INM IN PARTIAL FULFILMENT FOR THE AWARD OF BA/BSC DEGREE (BIT & MANAGEMENT) PREPARED BY STUDENT ID NUMBER: NOVEMBER 2008 INTRODUCTION Information can be managed in organisations so that it's potential for improving business performance and enhancing the competitiveness of the organisation can be realised by looking into aspects of organisations information. Information in an organisation is power because it is the key to the effectiveness and efficiency of how well organisation collects information and manages the information. It is the link between the history of the company and the future as the information management policy of an organisation could be the back bone of the company. In this age where information is very much valued, there is the need for strong information management systems for companies, this should be jealously guarded and secured, managed to the benefit of the company and the structure f the company in line with the organisation's line of business. THE ISSUES: . STRUCTURE OF SOFT AFRICA WEST (SAW) Soft Africa West organisation was established twenty years ago as a family business by two sisters with its head office in the UK where both founders lived at the time the business was founded. The main operation of the business is managed in the UK which serves as the head
How many squares are there on a chessboard?
How many squares are there on a chessboard? The aim of this investigation is to find out how many squares and rectangles of specific sizes can be found on a chessboard, and too see if there is a common sequence and algebraic formulae for each example. I have started with the simplest example that is to count the different combinations of squares on a range of boards from 2x2 board up to an 8x8 board. Results from the count 2x2 board x1=4 2x2=1 3x3 board x1=9 2x2=4 3x3=1 4x4 board x1=16 2x2=9 3x3=4 4x4=1 5x5 board x1=25 2x2=16 3x3=9 4x4=4 5x5=1 6x6 board x1=36 2x2=25 3x3=16 4x4=9 5x5=4 6x6=1 7x7 board x1=49 2x2=36 3x3=25 4x4=16 5x5=9 6x6=4 7x7=1 8x8 board x1=64 2x2=49 3x3=36 4x4=25 5x5=16 6x6=9 7x7=4 8x8=1 When the 8x8 boards results are analyzed a quadratic sequence can be identified i.e the second difference is a constant. term No of squares st diff 2nd diff 64 2 49 5 3 36 3 2 4 25 1 2 5 6 9 2 6 9 7 2 7 4 5 2 8 3 2 Using the general term for a quadratic sequence where A= 1/2 the constant 2nd difference, which is 2x 1/2 = 1 Yn=An + Bn + C So y1 = 1x1 + B x 1 + C = 64 So B + C = 64 - 1 B + C = 63 Y2 = 1x2 + B x 2 + C = 49 4 + 2B + C = 49 so 2B + C = 45 we now solve the simultaneous equation B + C = 63 2 B + C = 45 ?- B = 18 OR B = - 18 if B = - 18 then C = 63 - (-18)=81 so the
To be or not to be Molière: that is the latest questionwreaking havoc among French academics.
To be or not to be Molière: that is the latest question wreaking havoc among French academics. In "Corneille in the Shadow of Molière," a book recently published in France, Dominique Labbé, a specialist in what is known as lexical statistics, claims that he has solved a "fascinating scientific enigma" by determining that all of Molière's masterpieces - "Le Tartuffe", "Dom Juan," "Le Misanthrope," value="148422">"L'Avare" - were in fact the work of Pierre Corneille, the revered tragedian and acclaimed author of "Le Cid." "There is such a powerful convergence of clues that no doubt is possible," Mr. Labbé said. The centerpiece of his supposed discovery is that the vocabularies used in the greatest plays of Molière and two comedies of Corneille bear an uncanny similarity. According to Mr. Labbé, all these plays share 75 percent of their vocabulary, an unusually high percentage. Mr. Labbé's claim has upset more than the insular world of scholars. In the French collective consciousness, Molière is perceived as something of a national Shakespeare. Written in large part for Louis XIV and his court, Molière's comedies instantly became symbols of French culture thanks to their extraordinary dramatic range and extensive popular and scholarly appeal. As Joan Dejean, a professor of 17th-century French literature at the
internal and external program interfaces
Design of external and internal program interfaces The layout of the system is as follows. On the login screen there will be a space for which the user can enter their username and password. This is required in order to enter the system. When the box is clicked on by the user using the mouse, a flashing cursor will appear to show that it is really to type. This ensures that the user is aware of what is happening and makes it user friendly. The screen is uncluttered and has a login and cancel bottom to assist the user in the login of the system. This is shown to the right hand side. Once a login sequence has been completed and accepted by the system which matches it to a database that contains the correct usernames and passwords, the system then connects to the next screen where the bookings of shows can take place. From there on in, all the screens will look the same with just different instructions. This is to ensure consistency within the application as so not to confuse or distract the user. The logo will appear in the top right hand corner and the management button just below it. This will allow only the manager to view information that is suitable for him e.g. sales figures. This will not be allowed to be viewed by staff members by using a hierarchy system of usernames and passwords at the login stage. The first page shows a drop down menu by which the user can select

Under the weak form of market efficiency, the price of a security reflects all the available information about the economy, the market and the specific security, and that prices adjust immediately to new information. For a long time the conformation of random walk is considered to be a sufficient condition for market efficiency. However, rejection of random walk model does not necessarily imply the inefficiency of stock-price formation. Random walk is the path of a variable over time that exhibits no predictable patterns at all. If a price, p, moves in a random walk, the value of p in any period will be equal to the value of p in the period before, plus or minus some random variable. The random walk hypothesis states that

Instrument Calibration.
Instrument Calibration Introduction A new device that measures the concentration of fluorescence requires calibration. The device is calibrated using the calibration line, method of least square estimation can be used to estimate the parameters ? and ? and the validity of the estimates using measurement readings from observed data. The following are the measurements of fluorescence y, of a substance, A, in known concentrations x in ?g/m3, using the new device. Fluorescence (y) .0 8.0 6.0 24.0 32.0 38.0 Concentration (x) 0.0 2.0 4.0 6.0 8.0 0.0 Description of Data The fluorescence (y) of a substance, A and its concentration (x) has a linear relationship, where concentration (x) increases as fluorescence (y) of the substance increases. A linear model will be fitted to the observed data. The model is as follows: Straight-line regression . Fluorescence (y) is the dependent variable 2. Concentration (x) is called the regressor variable. 1, 2, ... , n here = e = Error ei is the error in the ith observation yi. Assumption on the errors . {ei} are mutually independent 2. E(ei) = 0 3. Var(ei) = ?2 We assume ei's are normal i.e. ei ~ N(0, ?2) 1, 2, ... , n Regression by Formula By using a mathematical method called the "Method of Least Squares" it is possible to find the values of ? and ? for in order to find a regression line.

Code model and the inferential model
Code model and the inferential model There are 2 different models of linguistic communication, the classic model, the code-model and the inferential model. Code model: The communicator encodes the message, by a signal, that the hearer than decodes. Sentences are just complex signals that encode messages. signals code messages The speaker selects the message and transmits the corresponding signal, which is received and decoded at the other end, when all goes well, the result of the reproduction in the receiver of the original message. On this approach, the communication is guaranteed as long as both individuals are functioning correctly, each has an identical copy of the code, and the signal is not destroyed. The code model exists in the nature, it is correct for animal communication. e.g.: bee dance, which used to indicate the direction and distance of nectar. Q: But how do human communicate? Example: Mary is angry with Peter and she doesn't want to talk to him. When he tries to engage her in conversation, she might: . stare ostentatiously at the ceiling. 2. open a newspaper and start to read it. 3. look angrily at Peter and clamp her mouth shut. 4. look angrily at Peter, put a finger to her lips and whisper `Shh`. 5. say `I m deaf and dumb`. 6. say `I won't talk to you`. * What do Mary's actions communicate to Peter? * Which, if any, of Mary's actions
In Anahulu, Sahlins argues that the Hawaiian people were not passive victims of their own history but rather the authors and that they played a significant role in the collapse of the ancient system of an all-powerful divine monarchy.
In Anahulu, Sahlins argues that the Hawaiian people were not passive victims of their own history but rather the authors and that they played a significant role in the collapse of the ancient system of an all-powerful divine monarchy. He emphasises that Hawaii did not simply capitulate and disregard their outlook on the universe when faced with the all-powerful western civilization. Rather Sahlins claims that the islands' ruling powers accommodated the western forces within their own mythology and where they might have visibly adopted western practices - for example the establishment of Christianity - this was only made possible by assimilating it with their traditional customs. In addition to this, the nature of the indigenous cosmology greatly amplified the effects of capitalism on the islands - an encouraged revelry in overt excess had a detrimental effect on both the inhabitants and the environment of the islands. The old order is constantly present throughout the seismic shifts in Hawaiian life that follow the appearance of the 'Haole' - not always explicitly, but as Sahlins states (p35) 'the O'ahu order was present as a structural condition. In order to fully comprehend the author's assertion, it is important to consider his theoretical background and place his work in an intellectual context. Sahlins is considered a neo-structuralist. Structuralism is an intellectual
This report is about the need to upgrade the new computer systems for our company.
There is a need to acquire a new computer system to bring substantial benefits to the company in the modern business arena. Report To: Members of the Board of directors Introduction This report is about the need to upgrade the new computer systems for our company. It also discusses the advantages and the disadvantages of both the old system which is currently used by our company and the new system available at present. The aim is to bring substantial benefits to the company by using a new computer system which supports multiprogramming and virtual memory. This is because quality of our products and services are very poor when compare to other companies which are using new computer systems such as Multiprogramming and Virtual Memory. There are several disadvantages and constraints appear in our current system. And also the current system is now nearly out of date and may fail to work properly. The maintenance cost is increasing and the quality of service which the system provides are decreasing. For these reasons it is time to analyze the current system and to introduce the new system very soon. The current system (Single User Batch System) The current system is using old technology called the batch system. It is used by several years all over the industrial countries and was very famous. Its growth brought many changes in the industrial world and human's
