Cyber Predators And Its Effects On Children - 1593 Words
Introduction: The cyber crime I have chosen is cyber-predators. Cyber predators are individuals who commit sexual abuse that begins or takes place on the Internet. Although the Internet did not create child predators, it has significantly increased the opportunities predators have to meet victims while minimizing detection. They can communicate with children anonymously through instant messaging, social networking sites, chat rooms, message boards, and even cell phones. Online predators do not fit any one mold or stereotype; seemingly upstanding citizens have been caught enticing children for sexual acts. Contrary to popular belief, most online predators are not pedophiles. Pedophiles target pre-pubescent children, while online predators typically target adolescents who engage in risky online behavior. (Wolak J, Finkelhor D, Mitchell K, Ybarra M. 2008). â⬠¢ Describe the type of cybercrime you selected. Predators take advantage of childrenââ¬â¢s natural vulnerabilities, such as their desire to appear adult or their need for attention. ââ¬Å"Groomingâ⬠is the process through which predators play on these vulnerabilities by offering children gifts and attention. It does not happen overnight. Grooming can be a long process that a patient, tenacious predator has planned and perfected to gain a childââ¬â¢s trust. This grooming may lead to the childââ¬â¢s willingness to meet the person with whom he or she is chatting.

Philosophical Argument ( 400 Words ) - 844 Words
PHILOSOPHICAL ARGUMENT (400 words) According to Sartre (1948, p.1) Existentialism is a principle that renders human life possible, through the affirmation that all truth and action denote an environment and a human subjectivity. A belief that the essence of man precedes that existence which we encounter through experience (Sartre, 1948, p. 3). Existentialism places the full responsibility for oneââ¬â¢s existence upon our own shoulders; putting a man in ownership of himself as he is, responsible for his own individuality (Sartre, 1948, p. 3). But he is also responsible for men, as he fashions a certain image of man, as I would have them to be (Sartre, 1948, p. 4). ââ¬Å"I think, therefore I amâ⬠, this is the supreme truth of consciousness as it attains to itself (Sartre, 1948, p. 9). Through this man invents and defines himself; this is specifically what Sartre means by ââ¬Ëfreedomââ¬â¢ and provides a connection to understanding ââ¬Ëselfhoodââ¬â¢ (Richey, 2015, p. 8). It is conceivable to be free without having explicit consciousness of our freedom (Vasey, 2010, p. 2). As if a person could simply be who he is, Vasey (2010, p. 8) states then he would be in the present, and the present tense would be just right for capturing his experience, his relationship to both himself and his world. At the core of existentialism, is the absolute character of the free commitment, by which everyone realises his or her selves in comprehending a type of humanity. Such humanity refers to a commitmentShow MoreRelatedHow Truth Was Defined By Medieval Europeans1696 Words à |à 7 Pagesthe beginning of the dark ages and use religion as the impetus for unifying all of Europe.

Death of a Salesman
Death of a Salesman -Characters Essay Willy Loman is destroyed by his own idealsWilly Loman is a travelling salesman who has worked for the Wagner firm for 34 years. He is now 61 years old and his job has been taken off salary and put on commission. He has a family and he boasts to them that he is vital in New England, but in fact he isnt vital anywhere. Willy has many strong beliefs that he strives to achieve. He wants to own his own business and he wants to be bigger than Uncle Charley and especially he wants to be a great success and he tries to emulate Dave Singleman. He wishes to die the Death of a Salesman and have many buyers and salesmen mourn for him. He also tries to be a good father, and husband. However Willys aims in life have been useless as he hasnt really achieved anything. He got fired by Howard, his sons are both failures and they abandoned him in a restaurant toilet. His relationship with his wife is plagued by his guilt for committing adultery. He has to borrow $50 a week from Charley. He cant even keep his mind on one thing for a long time. He cant drive a car. Willy gets so fed up with all of these things that he wants to commit suicide and eventually, he does. This topic suggests that Willys deterioration occurs because the principals he believes in. To a large extent this is true. After 34 years of Willys life, he loses his job. To a normal person under normal circumstances, being retrenched is a time when you feel useless. But for Willy, since everything else is going wrong at the same time, he feels like a useless old man. Willy thought that just because he named his boss, that he would have a secure future with the company but as Charley said them things dont mean anything? You named him Howard, but you cant sell that. Even though Willy wasnt even getting paid a salary, Howard didnt want him to even represent the company in case Willy cracked up again. Although Willy is mostly destroyed by his own ideals there are other things that destroy him as well, like Howard, Happy and Biff. Willy is emotionally destroyed when Howard fires him. Then, both of his sons disown and abandon him in Franks Chop House. Both Happy and Biff left their father talking to himself in the bathroom while they wanted to have a good night out with the girls. That also destroyed Willy because it showed that his sons didnt really care if he lived or died. Willy cant even drive a car though because he cant keep his mind on anything for a long period of time. In the past he has had a few car accidents because his mind keeps wandering Where are you guys, where are you? The woods are burning! I cant drive a car! Willy knows though that he is deteriorating and that nobody can help him except for him. Willy Loman, is indeed a low man. He has a very low self esteem and the only person that really doesnt love him is himself. Willy had great goals (ideals) in practice, but the only thing that he didnt realize is that if he didnt achieve those goals it wouldnt be the end of the world. Willy took it a step to far though, he thought that his life wasnt worth living anymore, therefore Willy Loman was definitely destroyed by his own ideals.

The Human Circulatory System Essays - Angiology,
The Human Circulatory System The human circulatory is one of, if not the, most important system in the body. ?It consists of such organs as the heart, and lungs? (Dunbar 4). ?However every organ and organ system in the body is nourished and kept alive through the use of the circulatory system? (2-4). The main organ in the circulatory system is the heart. ?Basically, the heart is a pump that keeps fresh blood coursing through your body, bringing oxygen and nutrients to all your organs and cells? (2). ?A mathematical description of what the heart accomplishes is astonishing. Your heart keeps approximately ten pints (4.73 liters) of blood constantly circulating through seventy ?five ?thousand miles (one ?hundred ?thousand kilometers) of blood vessels? (2). Those thousands of miles of blood vessels reach every organ in your body. ?Once they reach the organ they deliver much needed oxygen and take away carbon dioxide and other waste products that your body cannot use. This must be done without interruption if you are to remain healthy and alive? (2). ?Every living cell in your body depends on oxygen for life. Any cell deprived of oxygen for more than thirty minutes will die. The cells in your brain are even more dependent on fresh oxygen. If your brain cells are deprived of oxygen for only five seconds it will cause you to become unconscious. If your brain is deprived of oxygen for more than four minutes your brain will die? (2). But where does all of this oxygen come from? , You may ask yourself. The lungs, I believe, are the second most important organs in the circulatory system. For one reason they are the only way for oxygen to be received into the body. It is in the lungs that cells absorb fresh oxygen, and where carbon dioxide is released to be expelled from the body. The transfer of these two gasses takes place in the alveoli in the lungs. ?Alveoli are ?small cavities' or ?air sacs in the lungs'? (Marieb G-2). ?Blood entering the lungs through the pulmonary circulation is dark colored, low on oxygen, and high in carbon dioxide. The blood is pumped by the right side of the heart into the pulmonary arteries, which leads to the lungs. The pulmonary arteries divide into smaller and smaller blood vessels, which ending with pulmonary capillaries in the walls of the alveoli?(World Book L 528). These alveoli are the smallest of a series of cavities in the lungs. ?The lungs are designed to receive air, which enters the body through the mouth or the nose. The air passes through the pharynx and the larynx and enters the airways, beginning with the trachea and then into the two primary bronchi?(World Book L 527). ?After the primary bronchi enter the lungs they subdivide into smaller and smaller branches, called secondary and tertiary bronchi. Finally ending in the smallest of the conducting passageways, the bronchioles. This branching and re-branching is often referred to as the bronchial tree. The bronchioles lead into the respiratory zone structures, even smaller conduits, which eventually terminate in alveoli? (Marieb 380). Unlike the heart, which is made entirely of muscle, the lungs have no muscles in them. ?They are forced to expand and allowed to contract through movements of the ribs and the diaphragm. Like your heartbeat, the rhythmic motion of your lungs expanding and relaxing is a constant process. You can however control your breathi ng to a certain extent. For instance, if you feel like taking a deep breath you can do so instantly. But you cannot make your heart beat faster or slower on impulse. You have the power to hold your breath, but only for a short time. If you hold your breath long enough you will fall into unconsciousness and then resume breathing automatically. The reason behind this is that the muscles that control your breathing are controlled by your body's nervous system? (Dunbar 5). You see if your brain senses that it is not getting enough oxygen it will automatically force you to breath so that you can continue to live. ?William Harvey discovered that blood circulates throughout the body. He could not explain, however, the motion of the heart that makes circulation

Triangle Fire Essay
Triangle Fire Essay Triangle Fire Essay On a late Saturday afternoon in the year 1911, a horrific fire began at the Triangle Shirtwaist Factory in New York City in which over a hundred and thirty women died. According to writer, Robert Caro, ââ¬Å"some [women] died of smoke inhalation piled against the doors [from] trying to get out, some were burned to death and some jumped out of the windows;146 young women died [in all]â⬠(Youtube.com, 2011). In the year prior to the fire, the factory workers protested for more sanitary conditions as well as additional safety precautions. With that being said, it took the sight of dead bodies scattered across the sidewalks for safety standards to finally take place. The Triangle Factory had a profound impact on the regulations of private businesses. The newly established laws changed every aspect of the factory environment for the better. If business ownersââ¬â¢ had dangerous machinery, it would have to be regulated by the law. Based on the regulations provided by the video, â â¬Å"women would not be allowed to work more than 54 hours a weekâ⬠(Youtube.com, 2011). It is against the law to allow a child who is under the age of fourteen to work in a factory. The unfortunate tragedy of the Triangle Factory fire paved the way for safer working conditions across the country. In addition to business officials taking a stand by going to the state legislature and pleading that there needs to be reformed laws so a disaster like the Triangle fire does not repeat itself. Other state representatives such as Charlie Murphy, Al Smith, Robert F. Wagner, and Francis Perkins played important roles as well. Solid changes were made by the government to improve the working conditions of the factory workers. To provide a safe

Discover the Lithosphere in Plate Tectonics
Discover the Lithosphere in Plate Tectonics In the field of geology, what is the lithosphere? The lithosphere is the brittle outer layer of the solid Earth. The plates of plate tectonics are segments of the lithosphere. Its top is easy to see its at the Earths surface but the base of the lithosphere is in a transition, which is an active area of research. Flexing the Lithosphere The lithosphere is not totally rigid, but slightly elastic. It flexes when loads are placed on it or removed from it. Ice-age glaciers are one type of load. In Antarctica, for example, the thick ice cap has pushed the lithosphere well below sea level today. In Canada and Scandinavia, the lithosphere is still unflexing where the glaciers melted about 10,000 years ago. Here are some other types of loading: Construction of volcanoesDeposition of sedimentRise in sea levelFormation of large lakes and reservoirs Here are other examples of unloading: Erosion of mountainsExcavation of canyons and valleysDrying up of large water bodiesLowering of sea level The flexing of the lithosphere from these causes is relatively small (usually much less than a kilometer [km]), but measurable. We can model the lithosphere using simple engineering physics, as if it were a metal beam, and get an idea of its thickness. (This was first done in the early 1900s.) We can also study the behavior of seismic waves and place the base of the lithosphere at depths where these waves begin to slow down, indicating softer rock. These models suggest that the lithosphere ranges from less than 20 kilometersà in thickness near the mid-ocean ridges to about 50 km in old oceanic regions. Under the continents, the lithosphere is thicker ... from around 100 to as much as 350 km. These same studies show that underneath the lithosphere is a hotter, softer layer of solid rock named the asthenosphere. The rock of the asthenosphere is viscous rather than rigid and deforms slowly under stress, like putty. Therefore the lithosphere can move across or through the asthenosphere under the forces of plate tectonics. This also means that earthquake faults are cracks that extend through the lithosphere, but not beyond it.à Lithosphere Structure The lithosphere includes the crust (the rocks of the continents and the ocean floor) and the uppermost part of the mantle beneath the crust. These two layers are different in mineralogy but very similar mechanically. For the most part, they act as one plate. Although many people refer to crustal plates, its more accurate to call them lithospheric plates. It appears that the lithosphere ends where the temperature reaches a certain level that causes average mantle rock (peridotite) to grow too soft. But there are many complications and assumptions involved, and we can only say that the temperature would be from about 600 C to 1,200 C. A lot depends on pressure as well as temperature, and the rocks vary in composition due to plate-tectonic mixing. Its probably best not to expect a definitive boundary. Researchers often specify a thermal, mechanical or chemical lithosphere in their papers. The oceanic lithosphere is very thin at the spreading centers where it forms, but it grows thicker with time. As it cools, more hot rock from the asthenosphere freezes onto its underside. Over the course of about 10 million years, the oceanic lithosphere becomes denser than the asthenosphere beneath it. Therefore, most of the oceanic plates are ready for subduction whenever it happens. Bending and Breaking the Lithosphere The forces that bend and break the lithosphere come mostly from plate tectonics. Where plates collide, the lithosphere on one plate sinks down into the hot mantle. In that process of subduction, the plate bends downward as much as 90 degrees. As it bends and sinks, the subducting lithosphere cracks extensively, triggering earthquakes in the descending rock slab. In some cases (such as in northern California) the subducted part can break off completely, sinking into the deep Earth as the plates above it change their orientation. Even at great depths, subducted lithosphere can be brittle for millions of years, as long as it is relatively cool. The continental lithosphere can split, with the bottom part breaking off and sinking. This process is called delamination. The crustal part of the continental lithosphere is always less dense than the mantle part, which in turn is denser than the asthenosphere beneath. Gravity or drag forces from the asthenosphere can pull the crustal and mantle layers apart. Delamination allows the hot mantle to rise and yield melt underneath parts of a continent, causing widespread uplift and volcanism. Places like Californias Sierra Nevada, eastern Turkey and parts of China are being studied with delamination in mind.
