Vegetarian VS Meat

Introduction Food is the most basic need of man and all people have to eat in order to live. Obtaining something to eat is therefore an integral activity of the human experience. Naturally, human beings can live on meat and vegetables since they are omnivores. Eating meat and vegetables provides the required nutrition for a healthy body.Advertising We will write a custom research paper sample on Vegetarian VS Meat-Eating specifically for you for only $16.05 $11/page Learn More However, it is possible to obtain all the required nutrition from a diet that does not consist of animal or fish flesh. People who abstain from eating animal or fish flesh are known as vegetarians and they practice vegetarianism. On the other hand, people who supplement their vegetable diet with meat products are called meat-eaters.  Majority of the human beings on earth are meat-eaters. In the past few decades, there has been a move towards the promotion of vegetarianism. This m ove has been prompted by the alleged benefits of a vegetarian diet. This paper will set out to argue that being a vegetarian is more beneficial for the individual and the environment and as such, more people should adopt this practice. To reinforce this claim, the paper will highlight the many advantages attributed to vegetarianism and contrast them with the negative effects of meat eating. A Case for Vegetarianism Adopting a vegetarian diet will help a person avoid some diseases caused or promoted by meat consumption. Diseases such as diabetes, obesity, and heart disease can be caused or exacerbated by meat consumption. Researchers reveal that while genetic factors contribute to the contraction of these diseases, the dietary habits of a person increase or decrease an individual’s risk of developing the diseases (Hart 64). People who eat mean are more likely to develop obesity and heart disease than those who practice vegetarianism. In addition to this, a diet rich in fruits and vegetables improves the body’s blood circulation and actively prevents cardiac diseases. Vegetarians are therefore less likely to suffer from heart diseases compared to meat eaters. Practicing a meat-free diet will therefore improve the health outcomes of the individual. A vegetarian diet offers protection from the numerous public health risks associated with meat eating. Meat consumption exposes a person to many risks due to the diseases and medication offered to animals. Modern food manufacturing undermines the healthiness of meat. Unlike in the past where livestock was reared in a natural manner, farmers today engage in the indiscriminate use of antibiotics and food supplements to their farm animals. Henning explains that farmers engage in this practice in x order to reduce the susceptibility of their animals to diseases and promote growth (1086). While these practices achieve these desirable results, they do so at a major cost to meat eaters. Consuming the meat of ani mals that have been pumped full of antibiotics increases antibiotic-resistant human bacterial illnesses therefore creating a significant public health threat.Advertising Looking for research paper on health medicine?

Studies indicate that a meat-free diet significantly decreases the risk of death leading to longer life for the individual who practices vegetarianism. This relationship between vegetarianism and long life is due to a number of reasons. Singh and Sabate highlight that a vegetarian diet assists in the maintenance of a healthy weight and this contributes to long life by preventing the person from developing lifestyle diseases that lead to early deaths (265). A vegetarian diet also keeps a person safe from the many toxic components presen t in meat products. Singh and Sabate warn that animals reared for meat ingest large quantities of commercial feedlot additives (266). In addition to this, the meat contains saturated fat and consuming this is a risk factor for fatal diseases. Meat eaters are therefore likely to die earlier due to complications caused by their dietary practices.  A vegetarian diet can help mitigate the adverse environmental impacts caused by meat eating. Meat consumption in the world has increased exponentially in the last 6 decades. Due to the improved economic wellbeing of most people, the demand for meat has grown in countries all over the world. Animal product producers have therefore increased their scale of production in order to satisfy this demand. The environment has been significantly affected as cattle ranches have expanded. Henning illustrates that cattle ranching has led to widespread deforestation and it has contributed to â€Å"soil erosion, degradation of stream habitat, and desert ification† (1087). Animal production has also contributed to the unsustainable use of water resources. Huge water reserves have to be dedicated to animal production leading to the depletion of water resources. In addition to this, animals produce vast amounts of waste and in most cases, this effluent is allowed to leak into the environment thus polluting water reservoirs and degrading the environment. A vegetarian diet would ensure that this negative environmental impacts attributed to animal production are alleviated. A vegetarian diet can help increase the global food security. At the moment, the food production is able to satisfy the food demands of the human population. However, the high rate of population increase is raising concerns about the ability of the Earth to produce enough food for the entire human population. Because of meat consumption, high pressure is being put on the global food supply (McCarthy 122). Meat production requires large areas of land to be dedica ted to livestock rearing. This puts a strain on the limited land resources of the world. A lot of water is also needed to sustain the high level of meat production required by the modern world. Animals reared for food also consume products that can be eaten by human beings. Brown reveals that farm animals consume more cereal products that human beings do (28).Advertising We will write a custom research paper sample on Vegetarian VS Meat-Eating specifically for you for only $16.05 $11/page Learn More If the current rate of meat-consumption is pursued, the world will not be able to produce enough food for everyone. A vegetarian diet is more sustainable since it does not over-stretch the available land and water resources. In addition to this, vegetarianism will lead to higher cereal production since farm animals will not be fed on cereals that can be used to feed people. This will promote sustainable production and consumption of food products leading to global food security.  A vegetarian diet is more cost-effective than meat eating. A person uses less money to maintain a vegetarian diet than to engage in a meat-based diet. Even through the cost of meat has reduced significantly over the decades, meat is still more expensive than non-meat products. Lusk and Norwood confirm that â€Å"it is significantly more expensive to produce a pound of meat (or milk) than a pound of commodity crops† (112). McCarthy documents that the low cost of meat can be attributed to heavy government subsidization to meat producers (132). The final cost of these subsidies is incurred by citizens through taxation. Vegetarianism also helps a person to save money by promoting health. The meat-eater is forced to incur recurring medical expenses due to the numerous health issues promoted by meat consumption. Meat eating also leads to income reduction as the productivity of the meat-eater is reduced due to illness. These negative economic impacts can be overcome by adopting a vegetarian diet. This diet will ensure that the harmful effects of meat eating on an individual’s health are avoided. Arguments Supporting Meat Eating Meat plays a role in social events as people in a group setting enjoy it. People are able to celebrate and develop relationships as they consume meat communally. This unique role of meat in social events occurs because meat fulfills a deeper role than just providing the necessary nutrition and satisfying hunger among human beings. Meat has traditionally held a central position in global food culture. Holm asserts that meat is â€Å"the most highly prices, the most sacred and powerful† food in many cultures (277). The cultural significance of meat makes it a special meal that plays a crucial role in interactions among people. There is no disputing the fact that meat holds a dominant position in our culture. However, culture is not static and it is constantly changing to suit the circumstances of the time. The modern society does not have to perpetuate the dietary patterns utilized in the past. People can therefore take action to override the dominant meat-eating culture.  Meat eating is a sign of affluence in many societies. While the price of meat has significantly reduced over the decades, it is still higher than the price of most vegetable products.Advertising Looking for research paper on health medicine? Let's see if we can help you! Get your first paper with 15% OFF Learn More In a typical meal, meat produce are the minor component while the major components of the meal is vegetables. The association between mean-eating and prosperity results in meat being considered a food above all others. By consuming meat, humankind is able to demonstrate power and dominance over the rest of the natural world. Fiddes explains that historically, meat has always been the favored food of the wealthy and powerful elites in society (277). Meat therefore acts as a luxury good that human beings are motivated to acquire. While it is true that meat eating is seen as a sign of affluence, a vegetarian diet can also demonstrate affluence. In the western world, the vegetarian diet is mostly practiced by the well-educated and elite members of the society. On the other hand, meat is consumed by most people since it is widely available.  Meat plays an integral role in human development by providing some essential nutrients to the consumer. Singh and Sabate document that meat is the most important source of the essential proteins required by the human body (266). A study by a team of nutritional experts revealed that meat consumption ensures that a person gets the recommended level of essential minerals (EBLEX par. 3). Meat eating therefore ensures that the person’s immune system is boosted since essential minerals are acquired through the consumption of meat products. Critics of vegetarianism declare that meat is â€Å"an important source of high-quality protein and essential micronutrients† (EBLEX para. 4). Meat is a rich source of iron, key vitamins, and minerals such as potassium, selenium, and zinc, which contribute to long-term health. While meat is a rich source of essential minerals and vitamins, it also results in many adverse effects to the human body. Meat consumers are negatively predisposed to diseases such as diabetes and obesity. On the other hand, is a person obtains all the necessary minerals and vitamins from non-meat products, he/she will achieve overall health without the health risks associated with meat consumption. Conclusion This paper set out to argue that a vegetarian diet is preferable to meat eating. The paper began by defining vegetarianism and showing that this practice has gained prominence in the recent years. The paper then highlighted that vegetarianism can help prevent chronic diseases such as diabetes, obesity and heart disease.  A vegetarian diet will also contribute to the reduction in the environmental damages caused by meat eating and increase global food security. The paper has also provided some of the arguments in support of meat eating. It has shown that meat eating has some social and cultural attachments and contributes to the developing of society.  Meat eating plays a role in social events and it is also associated with affluence. In addition to this, meat consumption contributes to overall health by providing the body with essential vitamins and minerals. In spite of thes e positive attributes of meat, the evidence presented in this paper suggests that meat eating is detrimental to the well being of the individual and the society. Considering the numerous merits associated with vegetarianism, all development-minded citizens should take steps to adopt a vegetarian diet and encourage the abolishment of the meat-eating culture.

Transformational Change Essay Example

Transformational Change Essay Example Transformational Change Paper Transformational Change Paper Transformational Change John Hulka EXP105: Personal Dimensions of Education Instructor Eva Ananiewicz December 12, 2010 Transformational Change When you experience a dramatic change in your life, such as a career change or going back to school you are faced with learning a whole different set of skills and often doing this requires you to unlearn the old skills that you were so used to doing, and by doing this new kind of learning and as you are completing these dramatic changes in your life, you are broadening your horizons, (so to speak) you are opening your mind and realizing that there is always something new to learn and new ways in which to learn them, this is called Transformational Change. We do this kind of change in what is called a â€Å"learning cycle† and it is done in four stages. The first stage of the learning cycle is recognizing a significant problem, ask yourself what is the problem? Think hard and analyze the problem and look for possible solutions, the second stage is to narrow them down to the most logical solution. What solution will work best for you. After that plan carefully just how and what you are going to do, then (this third stage is the most crucial and causes the most stress) review and refine until your sure that you have a good well thought out plan, then the fourth stage is to implement your plan; put it into action, following these stages will help you decide on the best solution to your problem. Remember, that nobody plans to fail, they fail to plan. Let me briefly explain how this works and how I used this in my personal life: I was ordered by my Doctor to stop working and go on disability; as I need a heart transplant and the process is quite long. I was faced with a decision to just sit a home doing nothing till I get (or even if I was to get) a new heart or do something positive in my life. I chose to do something positive. So I realized the problem, and had to look at possible solutions : 1. Just sit at home doing nothing and wait. 2. Find a job I could do and risk losing my disability. 3. Go back to school, learn another career that I could do in case I could not get a heart. I chose #3. It was the most practical choice for me, and as it turned out it was the best one for me (because of my diabetes, I was taken off the transplant list) I chose to go back to school to become a therapist, something I could do Non-physical and something I was very interested in doing. The next step was to find the right school that would have the best course of action to complete my degree. After careful research, I decided on Ashford University. I then put my plan into action; I called and enrolled, and I am in class now. This Transformational change will be challenging, being out of school for 20 years will take some dedication, a good support system, and an open mind to learning. Jack Mezirow (1991) conducted research on adults engaged in transformational change and identified â€Å"Seven phases† typically occurring in the challenging learning process: 1. Experiencing a disorienting dilemma 2. Self-examination 3. Critical assessment of assumptions 4. Recognizinging that others have gone through a similar process 5. Exploring a process 6. Formulating a plan of action . Reintegration Out of these â€Å"Seven Phases† I have experienced many of them in my personal life. (in which I described in above paragraph) below are those â€Å"Seven Phases† and how they worked in my life along with a brief example of each, they are the following: 1. Experiencing a disorienting dilemma: on disability and what to do for the future. 2. Self-examination: Disabled, what to do. 3. Critical assessmen t of assumptions: Deciding on options 4. Exploring a process: choosing to go to school, and which school to go to. 5. Recognizinging that others have gone through a similar process: knowing that it can be done. 6. Formulating a plan of action: Looking for the right school, and get enrolled. 7. Reintegration: This one I expect to be going through, getting use to a new way of life something very different than I was use to. I will need to keep my motivation and a good support system in place. References: *   (Ashford’s text book) Learning online and achieving lifelong goals

Critique Article - Math for the young child or any math critique Essay

Critique Article - Math for the young child or any math critique article that deals with children - Essay Example There is immense value to the content of the article as it summarizes the results of the four year long researches on developing  the  Ã¢â‚¬ËœBig  Math  for  Little Kids’ pre-kindergarten and kindergarten mathematics program. The authors present ‘Big  Math  for  Little Kids’ as the  product of their effort from 1998 to 2002, to develop â€Å"a research-based and developmentally appropriate early childhood mathematics program  for  all pre-kindergarten and kindergarten children.† (Balfanz, Robert. et al, 2003, p. 264). The program consists of an all-inclusive set of sequenced learning activities and the lesson units of this program includes numbers, shapes, patterns and logic, measurement, operations on numbers, and spatial relations. The program, as the authors claim, combines mathematics into the daily routines and other early learning areas of the children such as music, art, movement, reading, writing, and science. It also presents mathematical symbols and words in the most cautious and meaningful ways aiming at the children’s lighthearted but purposeful learning of Mathematics. In their article, the authors not only provide the theoretical and research based evidences to the effectiveness of the program, but more significantly the evidences of the practical success of the ‘Big  Math  for  Little Kids’ from their observed results. After introducing the program the ‘Big  Math  for  Little Kids’ in detail, the authors deal with its research base which includes psychological and educational research as well as the design principles. They maintain that every child is capable of learning mathematics at a  young  age based on their researches. According to the authors, it is important to provide the children with adult guidance along with opportunity for play and they also specify that low-income children should

Information Technology Coursework Essay Example for Free

Information Technology Coursework Essay Input The Keyboard The keyboard is essentially based on the standard QWERTY keyboard used by typists. The main differences are the additions made by computer manufacturers. The first thing to notice is that the keyboard has three main sections. The first section is the main QWERTY keyboard, which has three extra keys. The most important of these extra keys is usually marked ENTER or RETURN. The enter key is on the right side of the keyboard and is used to tell the computer that you have finished typing and wish either to move to a fresh empty line or that you want the computer to carry out the typed instruction. The other two additional keys are the ALT and the CONTROL keys (CTRL). These act in the same way as the shift key on the typewriter and so allow normal keys to have a number of different effects. The second part of the keyboard is the FUNCTION keys. There are always at least ten and sometimes twelve of these labelled F1 to F10 or F12, which are grouped together on the left of the keyboard or along the top of it. They are used by programs like word processors or spreadsheets to give instructions to the computer. They do not normally produce an effect on the screen but can do in some programs. The third part of the keyboard is the numeric key pad. This is situated on the right of the keyboard and serves two functions. Firstly, to move the cursor and secondly to type numbers into the computer. The keys on the keypad usually contain the numbers 0 to 9, the decimal point and the mathematical symbols. The key marked NUMLOCK is used to tell the computer if the pad is used to enter numbers (NUMLOCK ON) or to move the cursor (NUMLOCK OFF). Input The Mouse A mouse is a device, which can provide an alternative to the keyboard. The mouse itself has a small ball in its base which, when pulled across a smooth surface, moves a special cursor across the screen. This cursor can be used to draw or point and is especially effective in providing an easy to use interface for those who have difficulty with keyboards etc. Processing The Central Processing Unit Inside the microcomputer is a tiny silicon chip called the Central Processing Unit or CPU: this can be regarded as the brain of the entire system. With the help of the computers internal memory it executes the instructions in a program by performing simple logical operations at very high speeds typically an instruction will be performed in millionths of a second. The chip containing the Central Processing Unit or CPU is the place where the computer does its thinking. The CPU processes information by fetching a program instruction stored in the computers memory, executing the instruction and proceeding to the next step in the program. The CPU contains (1) a program counter that tells the CPU where it is in the program. (2) an instruction register that stores the current program instruction. (3) a control unit that decodes the contents of the instruction register. (4) data registers that store the small units of information the CPU is currently processing. (5) a memory address register that holds the address or memory location of the information in its data registers. (6) an Arithmetic and Logic Unit (ALU) that actually performs each small step in the program, and (7) a status or flags register that reports on the work of the ALU. The size or power of a CPU is determined by the length of its registers: 8-bit processors work on information in 8- bit groups; 16-bit processors have registers that hold 16 bits and are twice as fast. 32-bit processors provide even more computing speed, and so on. Internal Memory RAM and ROM Because the central processing unit only works on small pieces of information at a time, the computer needs a way to store information while it is not being processed. Two kinds of silicon chips serve as the computers internal memory. Random Access Memory or RAM chips store information temporarily, and the computer can write, read, and erase information on them. RAM chips are erased every time the computer is turned off, so Read Only Memory or ROM chips act as the computers permanent memory: they store the instructions the CPU needs when you first turn it on. External Memory Disks and Disk Drives External memory devices like floppy disks, hard disks, and CD-ROMs store programs and data when the computer is turned off. When a disk is inserted into a disk drive, the computer can read information from it or write new information onto it. Only certain types of CD-ROM can have information written onto them. Output: The Printer Printers receive electrical codes from the computer and then print the corresponding letter or number on paper. The result is called hard copy. Plotters and some printers can even reproduce computer graphics on paper. Types of Printer Ink Jet Printers Ink jet printers work as their name suggests, by squirting jets of ink onto the paper through tiny nozzles. Ink-jets provide good quality output (on average 600 dots per inch) at reasonable speed and at relatively low cost. Laser Printers A laser printer is essentially a photocopier attached to the computer as an output device. Laser printers are capable of high quality output (around 720 dots per inch), at high speed. They can be bought from as little as around à ¯Ã‚ ¿Ã‚ ½100. Output Monitors (Visual Display Units) Monitors (V.D.U.s) are the most frequently used output device. The display is transmitted from the computer to the surface of a cathode ray tube, which is rather like a television screen. Slim, flat screen monitors are also available. The display consists of very small phosphorescent dots combined in different patterns to form words, numbers, and pictures. Monitors vary in their resolution (clarity), more dots on the screen means a higher resolution but obviously costs more. The range of resolutions are CGA, EGA and the highest resolution VGA. Software Computer Programs A program is simply a set of instructions, which the programmer wishes the computer to obey. The computer blindly obeys any instruction which it is given it possess no abilities to determine whether an instruction (so long as it is framed correctly) is the correct instruction for any given situation. Programs tell the computer how to turn the input you provide into the output you want. A program is therefore a detailed set of instructions for performing a particular task. Because you cannot actually touch programs they have become known as software; this contrasts with the hardware of a computer system monitors, chips, printers etc. which you can touch! Software takes many forms the computer system itself is co-ordinated by a special resident program called an operating system (you can read more about this program below), programs to carry out specific tasks for the user are termed application programs. Stock control, word processing, payroll and accounting functions are typical areas, which are serviced by application programs. Input/output Media Mass Storage Floppy Disks A floppy disk is 3 1/2 inches square. Inside its protective case or sleeve, each floppy disc is a circle of flexible plastic whose surface is covered with magnetic oxide. When you use a disc for the first time, you must use a special program called an operating system to format the disks surface by creating circular tracks divided into pie-shaped sectors. A hole punched near the hub of the disk lets the computer know where the first sector is. A track on each disk stores a directory that tells the computer where to find what information. This means that it can go directly to the correct part of the disk instead of wading through all of its contents to find the information it wants. A typical floppy disk can store around 200 pages of typewritten text, depending on how tightly the information is packed. If pictures are stored on disk, they take up a lot of room. Care of Floppy Disks Information is stored on floppy disk by means of magnetism. The information stored on a disk can be lost if the magnetic surface of the disk is damaged. When handling a disk you must be careful not to bend it or touch the exposed portions. Moisture, extreme temperatures, and exposure to magnetic fields or equipment can also ruin disks. You should keep back-up copies of all important disks to insure that your data will not be lost if a disk is damaged. You can guard against the possibility of accidentally writing over and erasing important data and programs by moving the small write-protect notch on the side of the disk. When this notch is closed, a sensor inside the drive prevents the head from writing onto the disk. Hard Disks All modern PCs have hard disks, which can store vast amounts of information this varies depending upon their size. Although they operate on the same basic principles as floppies, hard disks spin many times more quickly allowing the read/write head to pass only fractions of an inch over the disks surface. Hard disks are hermetically sealed in special chambers to prevent dust particles from ruining the disks surface. Disk Drives: Read/Write Heads To use a disk, you place it into a disk drive so that the circular hole in the centre of the disk fits into a cone in the drive. This cone spins the disk allowing all of its sectors to come under a window cut into the sleeve. As the disk spins around, a read / write head moves back and forth over the exposed portion of the disk. The head works like the head on a tape recorder. It reads information on the disk by translating its magnetic fields into electrical signals that are sent to the computer; information is written onto the disk when the head converts the electrical signals from the computer into magnetic fields on the disks surface. Operating Systems A computer is really a system of interconnected parts: a keyboard or input device; internal memory (RAM and ROM); a processor; disks and disk drives; output devices like a monitor and a printer; and, of course, software. A special kind of program called an operating system controls the flow of information between these different components. One of its most important jobs is to enable your hardware to understand the instructions of your software. When you buy a computer, you must be sure that its design or architecture is compatible with the operating system for which the software you want is written. The operating system manages the files on your disks and offers utilities such as formatting blank disks, listing the directory of files on a disk, as well as copying, renaming, and deleting files. Sometimes operating systems are permanently installed, but if the operating system is pre-packaged on a disk, its contents must either be loaded separately into the computer or written onto ev ery disk used, during the formatting process. Windows 95 and Windows 98 are the most common operating systems used today. Modems and Networks With the help of a modem, your computer can link up and communicate with other computers all over the world. The modem translates the computers language of ons and offs into tones of different frequencies, which are then transmitted across telephone lines. At the receiving end the process is reversed: a modem converts tone variations back into the computers digital code. Computer networks are systems of computers linked together in this way: they are used to send and receive electronic mail, and to allow small personal computers access to the vast data libraries of larger computers, via the Internet. COMPUTER APPLICATIONS Application Packages These are programs that actually perform the tasks that the user wishes to be done. The tasks are usually so complicated that several programs are required and these are collectively called a suite of programs. Typical examples of applications are Stock Control, Databases, Order Processing, Word Processing, Airline Booking Systems, Spreadsheets, Viewdata Systems and Point of Sale Systems. Each package will now be discussed in turn, to give a general explanation of what they are, when they are used and for what purpose. Stock Control A stock control system keeps track of all the stock currently held by the company. The computer is informed through the till when each item is sold. It is then an easy matter to deduct the number sold from the current stock level to give a new stock level. If this level is below a re-order level which again is held by the computer, then the computer can automatically print a re-order letter to the supplier. The number of each item to be supplied is stored and when the supplier delivers, the number of items delivered is added to the amount in stock. Therefore the company, in theory, should never, through its own efforts, run out of any item of stock and should at all times know how much stock it has, in the warehouse, in storage at a retail outlet and on the shelves. Losses through theft are easily calculated through a manual shelf count, and corrective action to reduce losses can be implemented quickly. Database A database is a store of information made up of records. A record contains information relating to one person or one company and is made up of individual pieces of information called fields. For example, you may create your records having the following fields: company name, address, telephone number, credit limit, amount owed, payment due etc. When all the information has been entered the database may then be used by searching for particular information, called cross-referencing (e.g. to find out at the end of the month who the company owes money to and how much, in order to settle their accounts). New information can be fed in and the database is changed (updated) to include the new data, so that it is always up to date. Large databases are best used with static information (remains the same), with new records being added to the end. An example of this type is a Library with records on all the books in stock. The computer operated by the DVLA in Swansea (Driving Vehicle Licensing Authority) might be an example of a large database. Information relating to every motor vehicle in the U.K. is stored on computer and can be sorted or searched to find out, for example, who owns a particular car. Word Processing In word processing a computer behaves like a much enhanced form of typewriter. Facilities are provided for entering, manipulating, storing and retrieving blocks of text. This means that standard letters and lists of names and addresses can be generated separately and then letters to everyone on the list can be printed without retyping the document. The processor retrieves the letter and the first name and address, prints the letter, retrieves the next name and address, changes the information in the letter, prints the next letter and so on. Real-Time Systems An example of a real-time system is Airline Booking. This is a system which updates the data immediately it changes. All the terminals in all the booking offices are connected via a telephone line to a large computer in the head office of the company. This is so that information can be accessed immediately and be changed on confirmation of a booking immediately. For example, if you wanted to book a flight, you would feed details into the terminal about the flight, and back would come a message saying perhaps that only two seats remain on that flight. If you then take these seats by sending that information back, confirmation would take place and then no-one anywhere in the world would be able to book a seat on that particular flight (even if they tried to book only ten seconds after you). Spreadsheet A spreadsheet is a special application package, which allows the user to set up tables of information and add up rows and columns which make up the table. They are used mainly for displaying cash forecasts of companies, in the form of a table where all the figures are interconnected. Each intersection of a row and a column is called a cell. The cells are filled with figures and then changes can be made and the spreadsheet calculates all the related cells, alters and reprints them. Figures can be changed and the overall effect on the complete table can be seen immediately.

information Needs Essay -- Technology, The Internet, Information Syste

Information needs Now a day’s Within the revolution and challenging in information and communication knowledge and technologies, stream of information enormously increased ( Huotari,2001) .The Internet is a new channel for academic resources, and contains the massive amount of information. Also it is significant that the user is conscious of the diverse information that is available on the Internet, and educated in what measurable should be evaluated (Case, 2007 ) . The most important function of information system if to occupied and full filed the needs for document s and information needs for the users. Recently classification and Identification of information needs is essential to the developed the information systems in general and also to the provision of effective information services (Budzik , Hammond, Marlow, & Scheinkman ,1998) . such needs are related to the instructive behavior and such needs to improve the users knowledge to make a decision . Each customer and user have a different type of information need depending on what they are trying to find , If organizations can determine the most common information needs , they can select the best components to address those information needs(Case, 2007) . internet provides sources to seek and achieve information and appropriate the information needs in different stages of the search process (Bhatti ,2010) .The first step to recognize information needs is to approve different and new methods to collects and gather information on the various factors that influence the information needs (Werner , Horst, & Werner , 1997) In Today’s world , within rise of the Internet and technologies , users are more closer to search and find they needs ,and its s... .... However most of the site outlined several major problems associated with information needs within a low quality and low value in hospitality industry In the competitive marketplace in each industry, publishing the information can help to attract the customers and improve the profit for the organization developmental advances ,In addition to determine the power full organizations Identification of information needs is essential factor to design information systems and to the provision of effective information services to the customers and users ( Customer Information needs is affected by a selection of aspects such as: The variety of information sources that available on the web site ; Selected that which information’s have to used ,awareness about the customer and users and the visitors background, needs , and individuality such as social ,economical (
