INTERNET CENSORSHIP
Censoring the Internet The internet offers a huge wealth of information both good and bad, unfortunately the vary nature of the internet makes policing this new domain practically impossible. The internet began as a small university network in the United States and has blossomed into a vast telecommunications network spanning the globe. Today the internet is ruled by no governing body and it is an open society for ideas to be developed and shared in. Unfortunately every society has its seedy underside and the internet is no exception. To fully understand the many layers to this problem, an understanding of net history is required. Some thirty years ago the RAND corporation, Americas first and foremost Cold War think-tank faced a strange strategic problem. The cold war had spawned technologies that allowed countries with nuclear capability to target multiple cities with one missile fired from the other side of the world. Post-nuclear America would need a command and control network, linked from city to city, state to state and base to base. No matter how thoroughly that network was armored or protected, its switches and wiring would always be vulnerable to the impact of atomic bombs. A nuclear bombardment would reduce any network to tatters. Any central authority would be an obvious and immediate target for enemy missiles. The center of a network would be the first place to go. So RAND mulled over this puzzle in deep military secrecy and arrived at their solution. In 1964 their proposed ideas became public. Their network would have no central authority, and it would be designed from the beginning to operate while in tatters. All the nodes in the network would be equal in status to all other nodes, each node having its own authority to originate, pass and receive messages. The messages themselves would be divided into packets, each packet separately addressed.
Each packet would begin at some specified source node and end at some other specified destination node. The particular route that the packet took would be unimportant, only the final results counted. Each packet would be tossed around like a hot potato from node to node, more or less in the direction of its destination, until it ended up in the proper place. If big chunks of the network were blown away, which wouldn't matter, the packets would still stay airborne, moving across the field by whatever nodes happened to survive.
In 2010, former senior U.S. officials conducted a simulation imagining of a catastrophic cyber attack, the origins of which came by way of a mobile application having malware that was self-replicating that eventually overwhelmed wireless networks and disabled portions of wired network communications and the internet as well as curtailing electrical supply channels and oil and gas pipelines (Corbin, 2010). Rather than consider the likelihood of such a catastrophe, the panel took the position that if such an event were to occur the government would have to take over telecommunications in this country, eight-five percent of which o...
Parkinson’s disease is “Characterized by the degeneration of the substantia nigra within the basal ganglia, causing a gradual decrease of the neurotransmitter dopamine” (Webb & Adler, 2008, p. 296). This disease is yet to have a known cause, although researchers are working hard in search of one. In other words, Parkinson’s disease is described as a dopamine deficiency in the caudate nucleus and the putamen (Webb & Adler, 2008, p. 176), and an excess amount of acetylcholine, a neurotransmitter. There is no answer as to why there is a breakdown of these nerve cells that cause Parkinson’s disease. Researchers are pointing to genetic and environmental factors that may be the cause (The Michael J Fox, n.d.).
Parkinson’s disease affects many area of the brain, this is because several different cells types degenerate and many different systems are affected. The various different chemical systems affected in the brain are: Substancia Negra, Locus Cereleus, Raphe Nuclei, Ventral Tegmental Area and Nuclues Basalus. () The area that is most affected in Parkinson’s disease, is the Substancia Negra. The cell in this part of the brain produce the neurotransmitter Dopamine. Generally about 50% of the dopamine producing cells have degenerated before motor symptoms of the Parkinson’s disease began. The dopamine released in the Substancia Negra are released in a physiological fashion in order to ...
Pesticides are grouped into what they call “families”. This is because they share similar ...
The term Silk Road does not refer to a single, clearly defined road or highway, but rather denotes a network of trails and trading posts, oasis and markets scattered all across Central Asia. All along the way, branch routes led to destinations off to the side of the main route, with one especially important branch leading to northwestern India, and thus to other routes throughout the subcontinent. The Silk Road network is generally thought of as stretching from an eastern station at the old Chinese capital city of Chang'an to westward stations at Byzantium (Constantinople), Antioch, Damascus, and other Middle Eastern cities. But beyond those end points, other trade networks distributed Silk Road goods throughout the Mediterranean world and Europe, on one end, and throughout eastern Asia on the other end.
To what lengths must a government go to protect its citizens from threats such as terrorism? This is a frequently debated and controversial topic. One of these so called measures is wiretapping without notice. The government should not randomly spy on its citizens because it is morally wrong and it violates basic human liberties such as but not limited to privacy.
The National Security Agency, better known as the NSA, has always been a vital asset for the United States. Ever since its inception in 1962 by then-President, Harry S. Truman, for the sake of deciphering messages sent between Germany and Japan, the role of the NSA has been to gather information on the United State's adversaries as well as protect information of its citizens such as credit information from theft. However, the NSA also has a third role which makes it a pivotal asset during wartime: carrying the tasks of the operation code-named Network Warfare. Over the past six decades, the NSA has created a reputable reputation for itself from deciphering messages during World War II to finding acts of terrorism beforehand via the Internet.

Parkinson’s disease (PD) is a progressive movement disorder marked by tremors, rigidity, slow movements (bradykinesia), and postural instability. It is a chronic, progressive neurodegenerative disease caused by decreased production of dopamine, a neurotransmitter. Dopamine is responsible for most of the body’s smooth muscle movements. As a result, motor control in Parkinson’s patients is disrupted, causing anything from uncontrollable tremors to muscular stiffness to slow-as-molasses movements. (2) PD affects about 500,000 people in the United States, both men and women, with as many as 50,000 new cases each year. The disease usually begins in a person’s late 50’s and 60’s; it causes a progressive decline in movement control, affecting the ability to control initiation, speed, and the smoothness of motion. The symptoms of PD are seen in up to 15% of those between the ages of 65-74, and almost 30% of those were between the ages of 75-84. (3)
It “is a progressive neurodegenerative disease that is the one of the most common neurologic disorders of older adults” (Ignatavicius & Workman, 2016, p. 867). The brain is the primary organ involved. In the area of the brain called the substantia nigra, dopamine producing cells are damaged or destroyed. Because there is a diminished number of the dopaminergic neurons, dopamine production is decreased. Dopamine is a neurotransmitter responsible for relaying messages to other neurons. Dopamine, together with acetylcholine, work to polish and synchronize movement allowing for smooth, purposeful physical motion. As one neurotransmitter, acetylcholine, elicit a response; the other, dopamine, inhibits it. This works as a well balanced act to control voluntary movement. The decrease in dopamine is what gives Parkinson’s disease its characteristic. Four chief signs are found in Parkinson’s disease: tremors, especially when at rest; muscle rigidity; bradykinesia or akinesia, slow movement which can lead to muscles freezing or no movement especially facial muscles in which the individual adopts a mask like feature called hypomimia; and impaired posture and balance, individuals lose coordination increasing the risk for
The history of the internet shows that the internet is not a new medium. The internet was initially created in the 1960's to as a way for the United States to stay connected in case of a nuclear fallout due to the possible consequences of the Cold War. F...
"Our environment is a heritage and our legacy that we all inherited"(Anonymous). Most people have no idea how this quote applies in their life. Have you ever wondered if what you are eating has something in it that can harm your health? Pesticides are harmful to the human health and the environment. They are used to kill insects and living organisms in growing gardens using different substances of chemicals humans but can be also affect and the environment. Some agricultural studies have showed the different effects of chemicals in pest control and how it has been enforced to society. Different communities around the world believe in changing the ways by using different methods like organic control or homemade pest control, which can result to more expensive but can make a difference in our lives.
Throughout the entire Unites States, 90-100 percent of almost every crop is sprayed with pesticides each year. Pesticides date back 4,500 years ago, when simple elements such as sulfur and mercury were used to stop pests from eating crops (Unsworth). However, today, pesticides have grown into an enormous industry, allowing 1.5 billion pounds of pesticides and insecticides to be used each year, being far more complex than simple elements. Since complex inorganic pesticides were first commercially produced in the US in the 1940’s (Unsworth), numerous have studied and wondered what impact pesticides have on the environment and the food consumed. As pesticides are extremely complex and created to often destroy weeds and bugs, they also can affect plants, ecosystems, and animals. Because pesticides are insanely toxic to animal environments and humans, alternative ways to prevent bugs and weeds must be executed.
The basal ganglia (BG) are responsible for a variety of functions, specifically providing adequate voluntary motor activity. They are an organized network, where different parts are activated for specific functions and circumstances. The motor circuit of the basal ganglia is the focus in this disease because PD is mainly thought to be a movement disorder (Obeso et al., 2008). Therefore, the level of the brain within the Central Nervous System that underlies the disorder is the cerebral cortex, and some subcortical structures. The cerebral cortex is the outer layer of the brain that is essential for higher mental and behavioral functioning. Underneath the cerebral cortex is where axons connect to and from the cortex and where interconnected clusters of cell bodies, like the basal ganglia, are located (Stirling, 2000, p. 61). The basal ganglia receive input from cortical areas, and transmit that input to the motor cortex through the thalamus, in order to permit movement. The substantia nigra is interconnected with the nuclei of the basal ganglia. Some connections are excitatory and some are inhibitory. The pars compacta part of the substantia nigra is where dopamine is produced. When there is a depletion, or low levels of the neurotransmitter dopamine in the substantia nigra, the balance of the output from the basal ganglia to the motor cortex is altered (Byrne
The world is in another cold war, except this time countries are battling for cyber supremacy. Cyberspace is a massive land of ever-changing technology and personal interaction (McGuffin and Mitchell 1). Cyberspace is not only a place where people post pictures and update their profile, but it also plays an enormous role in running a country. Advanced countries use computers to guide their military, keep track of citizens, run their power grids, and hold plans for nuclear devices and nuclear power. Risks to commercial and government concerns are now being noticed and many countries are taking actions to prevent such threats (McGuffin and Mitchell 1).
