Achromatopsia
When I was young, I was told that "color blindness" did not mean that the person saw the world like an old movie, but rather it meant that they could not distinguish between green and red. I thought that this understanding was very advanced and would quickly share my knowledge with any less-informed children. After looking into the matter, I have been forced to reject this generalization in favor of a broader range of diseases resulting in very different types of inabilities to perceive color in a "normal" fashion. While the typical color blindness I was told about affects 8 percent of men and less than 1 percent of women in the United States (1), there are many other types. The most common types of color blindness, effecting red and green vision, are not too serious for the sufferers, who can function normally and do not have overly impaired vision other than an inability to distinguish between certain colors. There are, however, more serious forms of "color blindness", such as blue cone monochromatopsia, partial rod monochromatopsia, and total rod monochromatopsia (3). The rod monochromats are also known as achromats, meaning they see no color at all. Only about 1/33,000 Americans has this disease, and women and men are effected roughly equally (3). This most severe variety of color blindness has many interesting symptoms which reveal a lot about rod vision.
Achromats have what can be called "night vision" or rod vision. This means that the only functioning receptors in their retina are rod photoreceptors. The cones are either absent entirely or are present but the signals are not being processed for some reason. There are two types of achromatopsia, one is congenital and the other can be caused by brain damage, called cerebral achromatopsia (3). There are also varying degrees of achromatopsia, with some sufferers being able to distinguish some color and others absolutely none. I will focus on the congenital version since cerebral achromatopsia varies in its symptoms and cause quite a bit, as well as being much more rare and so fewer cases have been studied. Congenital color blindness has more regular symptoms which can be used to demonstrate how rod-vision works.
One of the most noticeable things about an achromat that reveals their vision deficiency is sensitivity to light (8). Cone vision is what most people use during the day, since cones have less light sensitivity, meaning they can absorb more light without discomfort, although they too can be overloaded with light (like looking into the sun).

During the movie, Oprah makes a shift in Janie’s character by strengthening her mental and physical state. She becomes much stronger physically because when the storm approached and flooded the town, she pulled herself and Tea Cake out of the water. However, in the book, Ms. Hurston has it completely opposite from the movie; Tea Cake kills a dog during the storm to save his and Janie’s life then, the cow gets Janie out of the water and Tea Cake pulls himself out of the water. “Tea Cake split the water like an otter, opening his knife as he dived. The dog raced down the back-bone of the cow to the attack and Janie screamed and slipped far back on the tail of the cow, just out of reach of the dog’s angry jaws… Tea Cake rose out of the water at the cow’s rump and seized the dog by the neck… Then Tea Cake finished him and sent him to the bottom to stay there. The cow relieved of a great weight was landing on the fill with Janie before Tea Cake stroked in and crawled weakly upon the fill again” (Hurston 194). Zora’s purpose of making Janie weaker physically tells the story of a woman who cannot hold herself up on her own; ...
The movie and the book of Their Eyes Were Watching God both tell the story of a young woman’s journey to finding love; however, the movie lacks the depth and meaning behind the importance of Janie’s desire for self-fulfillment. Oprah Winfrey’s version alters the idea from the book Zora Neale Hurston wrote, into a despairing love story for the movie. Winfrey changes Hurston’s story in various ways by omitting significant events and characters, which leads to a different theme than what the novel portrays. The symbolisms and metaphors emphasized throughout the book are almost non-existent in the movie, changing the overall essence of the story. While Zora Neale Hurston’s portrayal gives a more in depth view of Janie’s journey of self-discovery and need for fulfilling love, Oprah Winfrey’s version focuses mainly on a passionate love story between Janie and Tea Cake.

People that have problems with vision due to albinism can’t fix their vision completely with glasses or contact lenses. The problems start in the eyes with poor development. Albinism reduced the pigment of the colored part of the eyes (iris) and the light sensitive tissue at the back of the eye (retina). They will not see things sharp and will have fast eye movement that can’t be controlled (nystagmus) and very sensitive to bright lights (photophobia). They could also have...
Although there is no way to treat colorblindness the people who have it have never known any different; it is not that big of a deal to them. I’m sure that people with colorblindness wonder what it’s like to see color the way other people see it, but t...

The Cuban Missile Crisis was a major event in U.S History that almost led to nuclear destruction. It was over a period of thirteen days in which diplomats from the U.S and the Soviet Union were trying to reach a peaceful resolution so that they wouldn’t have to engage in physical warfare. The crisis was the hallmark of the Cold War era which lasted from the 1950’s to the late 1980’s. The Cold War was a power struggle between the U.S and Soviet Union in which the two nations had a massive arms race to become the strongest military force. The U.S considered Communism to be an opposing political entity, and therefore branded them as enemies. Khrushchev’s antagonistic view of Americans also played a big role in the conflict. The Cold War tensions, coupled with a political shift in Cuba eventually lead to the military struggle known as the Cuban Missile Crisis. The Cuban Missile Crisis was the point of most tension and near collapse causing the Cold War to almost shift from a passive and underground struggle to a violent and catastrophic one.
It was determined that infants develop color vision at or around three months of age and that when final results were evaluated and compared to adult (only) measures, actually have better quality color vision (Brown et al., 1994). An interesting study by Chase (1937) made efforts to discover the identities of color in which infants that aged 2 to 10 weeks old were tested to find out what colors they could perceive. The results they came up with were that very young infants could tell the difference between the primary colors and combinations but there were numerous limitations to the study (Chase, 1937). The study had placed infants to lie down and view a screen while observing eye movements (Chase, 1937). Findings by Franklin, Pilling, and Davies (2005) explain that color categorizing occurs in four month old infants and adults alike. A study by Bornstein, Kessen, & Weiskopf (1976) has supporting evidence that color is categorized in 4 month old infants and determined the boundaries within...

This analysis explained the Cuban rebels in the Bay of Pigs invasion, the importance of the great leaders of the United States, the important decision making by the U.S. leaders, and the crazy leaders of the Soviet Union and Cuba. The Cuban missile crisis was a very dangerous episode, bringing the world’s major military powers to the brink of nuclear war. This event was important to world history and to all the main leaders involved. President Kennedy was assassinated shortly after that, but is still regarded as one of the best Presidents in U.S. history mainly because of how he dealt with that event. Fidel Castro and the country of Cuba are not recognized by the U.S. to this day and are still banned from trade. The Soviet Union has collapsed since the Cuban Missile Crisis and is now known as Russia. The Soviet Union is no longer a communist government and now gets along well with the United States. The bottom line is that this one event prevented a possibly world wide tragic nuclear war and has greatly affected the way the world is shaped today.
Criminology is the study of crime and criminals; a branch of sociology. More accurately, it is the study of crime as a social trend, and its overall origins, its many manifestations and its impact upon society as a whole. That makes it more a form of sociology than a law enforcement tool. But the trends it studies have a huge impact on the way the police do their jobs, the way society treats its criminals, and the way a given community goes about maintaining law and order. The writer will describe and give examples of the three perspectives of viewing crimes. The perspectives that will be highlighted are the consensus view, the conflict view or the interactionist view. Each perspective maintain its own interpretation of what constitutes criminal activities and what causes people to engage in criminal behaviors (Siegel, p.12).
