Effects Of Media Violence On Teenagers history homework: history homework

Effects on Media Violence and Young Children and Teenagers Violence and aggression have been seen often in nowadays media through music, commercials, video games, television and movies. Many argue whether the violence in media makes impact on people. Some claim there is no correlation between violence in media and reality. Christopher Ferguson, an associate professor in Psychology at Stetson University said “Basically, by … playing first-person shooter video game … you keep them off the streets and out of trouble”. He also said that “almost all young males play violent video games, and yet the majority are not committing crimes” (Scutti). Although this matter is challenging to be answered definitely, violence and aggression in media…show more content…

Video games aren’t the only source of exposing violence and aggression to young children and teenagers. Television is also a very common source. Over the past 30 years the rate of violence has increased. Back in 1950, only 10% of the household had televisions. However, now more than 90% of household have televisions. In fact, a lot of young adults have televisions in their own room. This give young adults the access to view whatever they desire without having the parental guide. Characters such as heroes appear on television or movies and they save lives. However, these heroes have characteristics such as being strong and violent. Even young children are using terms like “I have to catch the bad guys” when role playing with toy figures. Studies show that children in the United States watch approximately 28 hours of television a week. This is more than the time they spend in school. This leads them to view more than “200,000 acts of violence, including more than 16,000 murders before the age 18” (Beresin). Emmanuel Tanay said “Anything that promotes something can be called propaganda. What we call entertainment is really propaganda for violence. If you manufacture guns, you don’t need to advertise, because it is done by our entertainment industry.” (Kaplan). Perhaps this is the issue in our society. Because there is so much exposure to violence in variety ways of media, one may believe it is safer to own a gun for


Physics of Color Vision and Color Blindness help me with my history homework

What is Color?




To understand what color is, we first need to understand what light is. Light, as perceived by humans, is simply electromagnetic radiation with wavelengths between roughly 380 nm and 740 nm. Wavelengths below 380 nm and above 740 nm cannot be seem by the human eye. Electromagnetic radiation with a wavelength just below 380 nm is known as ultraviolet radiation. Electromagnetic radiation with a wavelength just above 740 nm is known as infrared radiation. The sun, black lights and fluorescent lamps are all sources of ultraviolet light. Heat is a source of infrared radiation, which is how thermal vision works.




Electromagnetic radiation between the wavelengths of 380 nm and 740 nm constitute light and the human color-vision…show more content…

Based on our current knowledge, there is no observable physical explanation (in our brains or elsewhere) as to how a 650 nm ray of light becomes “red”. As it stands, there’s no proof that one day you couldn’t wake up with your visible-color spectrum flipped. For more information on the debate between physics and psychological interpretation of sensory experiences, search for the term “qualia”. Now back to the physics (this is a physics webpage after all)…




The point is, color is a purely subjective experience that would not exist without eyes to see it. We can only understand color based on how we see color, even though other animals can see it differently. The human eye contains both rod cells and cone cells to interpret light. Rod cells interpret lower levels of light than cone cells; they also do not see color. In light environments, cone cells become activated and replace the rod cells as the primary source of visual information. Cone cells are the photoreceptors used to discriminate color.




The human eye contains three different types of cone cells which interpret their own ranges of electromagnetic wavelengths. These three cone cells are often oversimplified as the “blue, green and red” cone cells when, in fact, they each cover a range of colors. Each cone cell’s sensitivity to light is distributed as a bell curve over a range of wavelengths. The three cone cells


Progressive Form Of Optic Neuropathy ap history essay help: ap history essay help

Glaucoma is a progressive form of optic neuropathy that is characterised by structural changes to the optic nerve head (ONH) and corresponding patterns of functional visual field (VF) loss. It is a major cause of irreversible blindness in the world.  




Currently, the pathogenesis responsible for glaucoma is not well understood. It has been suggested that local ischemia or mechanical damage from a raised intraocular pressure (IOP) resulting in retinal ganglion cell (RGC) loss may have a role in its aetiology. The treatment for glaucoma aims to reduce IOP through therapeutic or surgical means to reduce glaucomatous progression. The first line of treatment involves topical therapy such as eye drops. There are many classes of anti-glaucoma drops with prostaglandin analogues being the most potent ocular hypotensive with a good safety profile.  




Before initiating treatment, it is important to consider factors such as the risk of progression and the patient’s suitability to the particular therapy chosen. Once treatment has been initiated, patients must be reviewed regularly to assess the efficacy of the treatment, monitor for adverse reactions, confirm compliance, and to identify signs of progression.  




Glaucoma is a form of progressive optic neuropathy that has clinically visible structural damage at the ONH and RNFL that correlates to a functional VF deficit1-4. These glaucomatous structural changes include thinning or notching of the NRR, bayonetting of vessels, loss of RNFL,
