...Too much computer exposure may hinder learning By G. Jeffrey MacDonald, The Christian Science Monitor For all the schools and parents who have together invested billions to give children a learning edge through the latest computer technology, a mammoth new study by German researchers brings some sobering news: Too much exposure to computers might spell trouble for the developing mind. | | | Key to the future: In Freeport, Maine, all seventh- and eighth-graders get their own laptop. | | | | By Melanie Stetson Freeman, courtesy The Christian Science Monitor | | From a sample of 175,000 15-year-old students in 31 countries, researchers at the University of Munich announced in November that performance in math and reading had suffered significantly among students who have more than one computer at home. And while students seemed to benefit from limited use of computers at school, those who used them several times per week at school saw their academic performance decline significantly as well. "It seems if you overuse computers and trade them for other [types of] teaching, it actually harms the student," says lead researcher Ludger Woessmann in a telephone interview from Munich. "At least we should be cautious in stating that increasing [access to] computers in the home and school will improve students' math and reading performance." With the rise of computers in classrooms has come a glut of conflicting conclusions about the actual value computers bring to timeless...

...In today's modern world, computers are an essential part of everyday life. Around the globe, children often use computers from a very young age. Although it is important for children to participate in various well-balanced activities, in my opinion, children who use the computer daily are actually developing a critical skill for future success. The bases for my views are personal, academic, and professional. From a personal point of view, computers are an invaluable resource to help young people explore the world around them. For example, children who use Internet to satisfy their curiosity about diverse topics are already becoming independent learners. No child with a computer is ever bored! By starting early in their lives, children feel totally at ease around computers; they are also able to take advantage of the wide range of services computers provide. From an academic viewpoint, children have no choice but to master this technological invention. For instance, when I was in university, students brought their laptops to class to take notes, do research and exchange information. They wrote assignments, created presentations and developed databases. Children who build early confidence and experience in these abilities are at a distinct advantage over those who have not. From a professional perspective, the computer has found a permanent place in the workplace. Today, employers still pay to provide computer training to their employees. Tomorrow, corporations will expect prospective...

...Compare and contrast the toolkit used by hunter-gatherers with that used by farmers. Throughout the ages, there have been tools used and created by man to simplify life as a hunter-gatherer. The earliest tool kits found from the 120,000-35,000 B.C.E. are great examples of simple tools made out of stones. Rough pieces of the stone chipped away to create somewhat of a point on the tip of the rock that could later be used as weaponry such as on a spear or as an everyday tool used for cutting. Through progression of practice and time tools became more evolved. Shapes became more defined and new tools developed. Different materials were used such as bone from animals and natural fibers such as sticks that were used to makes harpoons for hunting and needles for clothes making. As hunting and gathering became insufficient due to growing populations humans began to settle down and domesticate their own crops and animals to feed themselves. Tools of the hunter-gatherer became more sophisticated as they settled into becoming farmers. Farmers used materials of stone, bone, antlers and natural fibers like the hunter-gatherers of the later years. They became more skilled at working the stones and materials polishing them into pieces of functional art. Tool use was not only for food but for other jobs such as clothes making and house building. The difference between hunter-gatherer’s and farmer’s tool kits are the details. The hunter-gatherers did not put as much emphasis on decorating...

When it comes to selling a product Old Spice tries to make the costumer think that if they get their product it will change them. Can think of a company that uses weasel words more than Old Spice does with their advertisement? Old Spice tries to make it seem as if, by purchasing their product, you will all of a sudden have a much more glorious life. Old Spice is notorious for misleading an audience into buying their product. They have multiple commercials where they use doublespeak to try and make their product sound better. Old Spice also frequently uses weasel words as well as doublespeak to get people more interested in their product. Lutz said this about weasel words, “Weasel words appear to say one thing when in fact they say the opposite or nothing at all.” (Lutz 310) Lutz describes doublespeak as, “It is a language which makes the bad seem good, the negative seem positive, the unpleasant to seem attractive, or at least tolerable. “ (Lutz 304) Old spice has multiple commercials making false claims of how you can be changed by their product. As a consumer of any product you must be aware of what ads trying to sell you. Old Spice Champion is trying to get people to “Believe in your smellf.” Many consumers buy Old Spice Champion for misleading reasons, but no consumer should ever buy Old Spice...

...A Dangerous Moment English class was a place where I could sit back in a chair and let my imagination run wild. I always had As in English not even an A- would ever slip by. Ms. Bottineau was a great ball of joy every day of the week, every day I entered that classroom a sense of relief would flow through my veins, I looked up to her and I know she had trust in me to always give my 100% effort in every assignment. At this point in my sophomore year I was chilling like a villain, it was almost the end of the school year around March in Ms.Bottineau’s class and we had to memorize a poem titled “Our Deepest Fear”. This is where my deepest fear of losing my English teachers trust became a reality. I quite possibly made the most foolish mistake of my life, a mistake that made me, a 16 year old teenager cry in regret. March 27th was a day my life would take a major turn. The night before the test I thought about studying the poem but I really don’t know what was in me that I decided to procrastinate and to not memorize that poem as if I had absorbed the aura of a sloth. The next day as I enter the classroom and I notice the laptop carrier open, ready for us to grab, as if they were taunting me with failure already. I was sweating and almost ready to faint. The pressure was on, I had to make a choice and I made the most horrendous one a human can make. A decision that break bonds, trust, and one's reputation. I am already regretting not being prepared. I had a plan, a very idiotic...

...Using Computer Modeling to Explain the Theory of Evolution by Natural Selection Throughout The Blind Watchmaker Richard Dawkins attempts to use computer modeling to explain and defend various aspects of the theory of evolution by natural selection. Where Dawkins’ computer modeling comes into use in a significant way is discussed in Chapter 3 of his book titled, “Accumulating Small Change”. In it, Dawkins takes the reader through explanations of what cumulative selection is and how it builds up biological complexity in a meaningful, and relatively quick, way. He does this with computer modeling and continues on with various other examples of computer models to explain how genes work, what mutation looks like, and how it gets selected. The following is a look at how he uses computer modeling to these ends and what their limits are, essentially, what sort of questions they can answer. Dawkins begins Chapter 3 of The Blind Watchmaker by posing the question of how living things came into existence if not by chance. He explains that it was by a series of “gradual, step-by-step transformations” from entities simple enough to have come about existing by chance transitioning into entities which are incredibly complex and which could not have come to exist by chance alone (Dawkins 43). This transitional process is achieved through “nonrandom survival” and is known as cumulative selection (Dawkins 43). From here we are told about the difference between single-step selection...

...JANE B. CASIL BSCS-III THE TEN COMMANDMENTS OF COMPUTER ETHICS 1. Thou shalt not use computer to harm other people. -Oftentimes we use computers for so many reasons to discover new things, meet other people and etc. But sometimes we didn’t care anymore the important of using our computers if it is doing the right thing or not. So that, in order to avoid this kind of computer ethics we should know our limitations in using our computers because other people might have the tendency to become more rude and there’s a possibility that may affect in one’s life if we didn’t look for a better solution on this. 2. Thou shalt not interfere with other peoples computer work. -There are people who truly satisfied with their work, who patiently trying their best and to work hard but sometimes there are reasons why people interfere other work maybe because it is easy to them to look for others work. They actually don’t mind that if this action is good or bad. 3. Thou shalt not snoop in other peoples files. -We should always mind in ourselves that we are free to let our choices for an easy task but avoid snooping files with other people. 4. Thou shalt not use a computer to steal. -Computer is use for doing the right thing and we should know this in every single way.

...– 1956: First Generation [ Vacuum Tubes ] These first generation computers relied on ‘machine language’ (which is the most basic programming language that can be understood by computers). These computers were limited to solving one problem at a time. Input was based on punched cards and paper tape. Output came out on print-outs. The two notable machines of this era were the UNIVAC and ENIAC machines – the UNIVAC is the first every commercial computer which was purchased in 1951 by a business – the US Census Bureau. 1956 – 1963: Second Generation [ Transistors ] The replacement of vacuum tubes by transistors saw the advent of the second generation of computing. Although first invented in 1947, transistors weren’t used significantly in computers until the end of the 1950s. They were a big improvement over the vacuum tube, despite still subjecting computers to damaging levels of heat. However they were hugely superior to the vacuum tubes, making computers smaller, faster, cheaper and less heavy on electricity use. They still relied on punched 1964 – 1971: Third Generation [ Integrated Circuits ] By this phase, transistors were now being miniaturised and put on silicon chips (called semiconductors). This led to a massive increase in speed and efficiency of these machines. These were the first computers where users interacted using keyboards and monitors which interfaced with an operating system, a significant leap...

...bandwidth or connectivity. Bandwidth attacks overflow the network with a high volume of traffic using existing network resources, thus depriving the legitimate users of these resources. Connectivity attacks overflow a computer with a large amount of connection requests, consuming all available operating system resources so that the computer cannot process legitimate user's requests.” (EC-COUNCIL 6-3) Our network has suffered a type of DoS attack that was carried out by many computers throughout the campus network; this is called a Distributed Denial of Service (DDoS), or a DoS attack that was initiated by many computers. Our systems were attacked by computers owned by the school and the attack was carried out using computers on the internal network. The computers were compromised by an individual (or group of individuals) that gained access to the network by using a network administrator’s password. This password was obtained by a piece of software that logs key presses on the computers. They then used the password to install a piece of software with administrative privileges. That piece of software is what brought down the registration server. The attacking software asked the registration server for a webpage over and over again. This request was make with different ports on the individual computers and the server attempted to fulfill each request. Each computer that was infected by this software was able to make hundreds of requests in a matter of seconds...
