Television TELEVISION We have at least a television in our home. television allows us to hear and see events as soon as they happen. If our grandma's mother or father see TV, they'll suprised and say 'This is diablo's machine!'. We watch TV at least two hour in a day. HOW WORKS TV? When a TV program is broadcast the sound and picture are sent out simultaneously by two different radio systems. The TV camera takes the picture. Camera is the most important part of the camera. The light from the object is allowed to fall on a light sensivite plate located inside the camera tube by the lens. This plate consists of thousands of light sensivite particles which act as photoelectric cells. Each photoelectric cell gives off electrons in the same proportion as the light falling on it. This forms an image on the plate. The bright and dark spots form an electric current which leaves the transmitter as carrier waves. These waves are picked up by the receiver. The TV receiver picks up both the sound and the picture. The antenna of the TV set picks up the weak current and passes it to a cathode ray tube which is called the picture tube. The electron beam scans the screen of the picture tube in exactly the same way that it scanned the target of the camera tube and a picture is formed on TV screen. The image on the screen changes 25 times a second and, since we can't detect individual pictures moving at this speed, we see a continuously moving image. WHO INVENTED THE TV? Television wasn't invented by a man. Many people helped for inventing TV. (For example German Nipkow (1884) , Russian Rosing (1911) , American Zworikin...)

Dinosaurs at the American Museum of Natural History

Dinosaurs at the American Museum of Natural History Visiting the fourth floor of the American Museum of Natural History in New York is a bit like dying and going to dinosaur heaven: there are over 600 complete or near-complete fossils of dinosaurs, pterosaurs, marine reptiles, and primitive mammals on display here (these are just the tip of the prehistoric iceberg, since the museum also maintains a collection of over one million bones, accessible only to qualified scientists). The large exhibits are arranged cladistically, evoking the evolutionary relationships of these extinct reptiles as you go from room to room; for example, there are separate halls devoted to ornithischian and saurischian dinosaurs, as well as a Hall of Vertebrate Origins devoted largely to fish, sharks, and the reptiles that preceded the dinosaurs. Why Does AMNH Have so Many Fossils? This institution was at the forefront of early paleontology research, represented by such famous paleontologists as Barnum Brown and Henry F. Osborn- who ranged as far afield as Mongolia to collect dinosaur bones, and, naturally enough, brought the best samples back for permanent exhibition in New York. For this reason, a whopping 85 percent of the display skeletons at the American Museum of Natural History are composed of real fossil material, rather than plaster casts. Some of the most impressive specimens are Lambeosaurus, Tyrannosaurus Rex and Barosaurus, among a cast of hundreds. Planning to Go? If youre planning a trip to AMNH, keep in mind that theres much, much more to see than dinosaurs and prehistoric animals. This museum has one of the worlds best collections of gems and minerals (including a full-sized meteorite), as well as vast halls devoted to extant mammals, birds, reptiles and other creatures from around the globe. The anthropology collection- much of which is devoted to Native Americans- is also a source of wonder. And if youre feeling really ambitious, try attending a show at the nearby Rose Center for Earth and Space (previously the Hayden Planetarium), which will set you back a bit of cash but is well worth the effort.

In order to achieve this larger objective, the course initially explored the key strengths and potential of the team. The areas where the team has to focus in terms of further development of the company were highlighted in the course. However, it is very important to identify the obstacles that current team faces in terms of having focused objectives and working towards achieving them. It is very important to overcome these blocks so that the company and the team could grow further. It becomes the responsibility of the planning division to develop strategies in order to tackle these cha llenges. These four key areas were thoroughly assessed as a blueprint of the current status of the team was created. This motivated the team to a large extent and also provided clear insight on areas of intervention and also on the organizational weaknesses. A brainstorming on each team member’s understanding of the team was conducted. This process revealed the attitude that the team members had towards the department. The team members came up with the feeling that the planning division is the Heart and Brain of ADNOC. Several strengths and characteristics of the department were highlighted.

A study of citizenship and its relation to surveillance and privacy Essay Example for Free

A study of citizenship and its relation to surveillance and privacy Essay Citizenship as Surveillance   Ã¢â‚¬Å"When you single out any particular group of people for secondary citizenship status, thats a violation of basic human rights†- Jimmy Carter. Often taken for granted, citizenship is something that we know superficially what it is, but never think too deeply about. But every single day, for millions of people, citizenship is something to be worried about, something that others use to rise above the rest. Based on personal experiences as well as extensive research, this essay will discuss not only what citizenship at its core is, but also its uses as surveillance and how it impacts everyday life. I will be drawing primarily from concepts detailed by three scholars in the area of surveillance- David Lyon, Steven Nock, and Michel Foucault, with some material from John Torpey. From Lyon, I will be referencing the ideas of social sorting and data flow; from Nock, I will be referencing the idea of credentials; from Foucault, I will be referencing the idea of disciplinary power. Furthermore, I will be looking at the impact of these concepts from each scholar onto the issues of social exclusion and discrimination. Through such an analysis, I will detail the net benefits and harms of citizenship as it pertains to surveillance and the everyday person. What is citizenship? Webster’s Dictionary simply defines it as â€Å"being an inhabitant of a city or town; especially one entitled to the rights and privileges of a freeman†. But of course, this is an incredibly superficial definition. At it’s core, according to John Torpey, citizenship is a way for states â€Å"to deprive people of the freedom to move across certain spaces and to render them dependent on states and the state system for the authorization to do so an authority widely held in private hands theretofore†. While citizenship, at first glance, simply seems to be just another way to distinguish between nationals of one state opposed to nationals of another, its use for governments goes far greater than that. The creation of passports and other such devices has led citizenship to not only be simply documentation, but also a method of control and surveillance. As Torpey furthers, â€Å"A critical aspect of this process has been that people have a lso become dependent on states for the possession of an identity from which they can escape only with difficulty and which may significantly shape their access to various spaces†. While originally just a way for states to determine borders and other logistics, citizenship over the years has evolved greatly. From passports and Social Security numbers to crime databases and border patrol checks, the methods by which governments restrict and control our movements are growing. However, the question remains: How do states use citizenship to surveil its citizens? The primary way governments surveil its citizens through citizenship is the creation of passports. Passports allow for entry into the issuing country and are accepted as valid identification for international border crossings. Because passports are used as identification, they contain information such as name, date of birth, and biometrics. However, past simple identification, passports also serve as a means of surveillance is by providing identification/classification as well as tracking/restricting movement. As Torpey states, â€Å"states have sought to monopolize the capacity to authorize the movements of persons and unambiguously to establish their identities in order to enforce this authority†. As detailed before, the ultimate goal of citizenship is to restrict and control the movements of persons. The role passports play in this is by establishing the identity of such persons in order to better restrict them. Passports act as a credential, which, as Steven Nock writes, is â€Å"a way to create reputation among strangers, or â€Å"A minimum basis for trust in the absence of personal knowledge†. He further, saying that credentials are necessary to the extent that we must trust people we don’t know. In this case, passports act as a simple way for law enforcement to ensure criminals are not moving about freely. As such, checking passports at border crossing or flights not only establish identity, but also trust. The way passports do this is through data flow. As defined by David Lyon, data flow is the transferring of information collected by one surveillance technology to another. In the case of passports, most, if not all, have an embedded chip that allows police, border patrol agents, and the like to simply swipe a passport to pull up all of a citizen’s history. Most notably, this chip contains data from the TECS (Treasury Enforcement Communications Systems) which allows different law agencies to exchange criminal information with each other. That means that your entire criminal record, whether it be with the Border Patrol, the FBI, or even the local police, can be found with just a swipe of your passport. But even more so, this data is then used for social sorting. Social sorting, as defined by David Lyon, is â€Å"the social practice of surveillance and control to sort out, filter and serialize who needs to be controlled and who is free of that control†. At face value, this seems to be a good thing. After all, ensuring criminals are walking around free sounds like a good deal for a small invasion of privacy. However, the issue comes with the use of social sorting today. As Lyon states, â€Å"the new penology is concerned with techniques for identifying, managing and classifying groups sorted by levels of dangerousness. Rather than using evidence of criminal behaviour, newer approaches intervene on the basis of risk assessment†. Instead of allowing or denying movement based on tangible criminal behavior, the use of such data has moved towards prediction of criminal behavior. As such, social sorting in the case of citizenship has progressed past simply who is a criminal versus who is not a criminal and instead sorts people based on who is likely to become a criminal. The impact of this to everyday life is great. One specific way is through the idea of disciplinary power, which is, as Foucault defines it, the idea that â€Å"Discipline is a mechanism of power which regulates the behaviour of individuals in the social body.† This simply means that the use of surveillance allows institutions to use discipline to enforce specific behaviors within people. In the case of citizenship, this disciplinary power exists in two ways. Firstly, it exists from the government. A historical example of such is the case of the Soviet Union and Soviet passports. In this case, the Soviet Union issued passports based on who supported the Soviet ideology. Those who were completely indoctrinated were allowed to travel freely; however, those who did not support the Soviet ideology were effectively restricted to poor areas. As such, the Soviet Union used disciplinary power (restricting movement based on ideology) in order to promote a specific behavior (supporting t he Soviet ideology). In this case, it’s directly from the government itself. However, the second way disciplinary power exists in citizenship is through the deinstitutionalization of disciplinary power, as offered by William Staples. Instead of the government itself directly enforcing specific behavior, this type of disciplinary power relies on other citizens to promote citizenship. And indeed, this concept is prevalent even today, with prejudices against the â€Å"foreigners† and the â€Å"illegals†. This kind of social exclusion and discrimination promote the idea of citizenship if only to escape the attacks of others. Talking to my parents, who immigrated to the United States from China, I found it interesting and slightly disheartening to hear their experiences. They way people treat citizens and noncitizens if very different. Because my parents didn’t speak very much English, communication was an issue and it was difficult getting jobs. There was a certain amount of prejudice against immigrants and not being a citizen incurs a certai n amount of suspicion. After all, citizenship is seen as a â€Å"patriotic duty†, and not engaging in such a process can be perceived as not embracing the American culture. While the difference in attitude wasn’t immediate and polarizing, there was a lot more acceptance when my parents became citizens. The attitude of those around them became more akin to that of a community rather than sticking out like a sore thumb. As such, from this experience, I found it clear the impact that disciplinary power had upon citizenship and social exclusion and discrimination. There’s a certain â€Å"us versus them† mentality, and the stigma associated with not being a citizen is great. As such, it’s clear the impact citizenship has on everyday life. Although it may seem innocuous, the role citizenship plays in surveillance is great. With the use of credentials and data flow, citizenship ultimately results in issues such as social sorting and disciplinary power. What then results is a great amount of social exclusion and discrimination based solely on the characteristics of citizenship. From immigration to criminal activity, everyone is subject to judgement and the increasing pervasion of privacy only exacerbates these impacts. While there does need to be a certain amount of credibility associated with each person, the overreach of states through surveillance will only result in increased tension and stratification.

Its All Downhill :: Personal Narrative Essay Example

It's All Downhill From Here 8:02 a.m. Saturday. It's still dark, as usual, on these cold, winter days. Everybody else is still sleeping and enjoying the comfprting heat of their beds. I crack open the locked window by my bed, an act some deemed downright idiotic. I strip off my pj's, throw on my robe, and head for the shower. Drying off, I think about where I am abou to go. I dress piece by layered piece. I can't wait to hit the slopes! I round up my tools: body, boards, boots, bindings. Everything is in working order and ready for take-off. As I open the front door, I am shocked by the cold and fight my way through the wind to my car. I turn the key and put the heater on full blast. I am almost there. I step out of my car and survey the parking lot. Not too many cars. That's the way I like it. I take a deep breath and savor the frsh air. Already, I can feel the pressure of deadlines lifted off my chest. I strap my skis on, and prepare not just to tackle a run but other situations in my life as well. I skate over to the first pitch of the double diamond slope, and map out where I will take the first couple turns. It is almost like I am assessing my goals in life: getting accepted into Syracuse, owning a house in Colorado, raising a healthy family. I appreciate the sound of carving the first turn as if it was my very last. The crunching of the snow under my feet empowers me to crush the antagonists in my everyday life. The second and third turns secure my self-confidence. Only with the fourth turn do I start to realize that things are not always that easy. I heard it said often, "It's easier said than done." I never believed it until now. I only skid slightly over a patch of ice, but it is enough to start my heart thumping. I am suddenly aware that to finish this run or to reach my goals, I have to be ready for the tricky spots. I know that at any moment I could fall and be forced to start over. My lifetime goals can be affected by any number of things - grades slipping, drugs and alcohol - and I have to be ready to handle anything.
