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).
ACHONDROPLASIA is known as being undersized, or less than 50in. in height. Having short limbs, a normal sized trunk, large head with a depressed nasal bridge and small face. This is a result of a disease in the thyroid gland. It can also be caused by Down syndrome or absorption, a cartilaginous tissue during the fetal stage. Hypochondroplasia, a mild form of dwarfism. Spinal tuberculosis and the deficiency of the pituitary gland secretions. Treatment with thyroxin or thyroid extract early in childhood results in normal growth and development. Somatrophin, also known as the human growth hormone is secreted by the anterior pituitary. Respiratory problems start to occur in infants. Symptoms of problems include snoring and sleeping with neck in a hyperextended condition. The limbs have rhizometic shortening. The legs are straight in infantry but when a child. He begins walking they develop a knock-knee position. When the child continues to walk legs begin to have a bowed-leg look. Occasionally, these curvatures are fixed. As the child continues to walk the kyphosis disappears and the back assumes a lordotic posture. If a delay in child’s walking occurs, the spine should be monitored closely for signs of gibbous formation. In infancy, hypercephalus can occur. Infants head circumference should be monitored close . Monthly checks of head circumference must be monitored. Radiologic studies are indicated if head circumference raises to disproportionately, or if symptoms of hydrocephalus. Child’s pediatrician should have a copy of head circumference curves for children with achondroplasia. Radiologic procedures for dwarfism include head ultrasound, C-T scan, or MRI of the head. If intervention is necessary, a ventriculoperitoneal shunt is placed relieving the pressure. Infants should also be monitored for foramen magnum compression. It is the opening at the base of the skull in which the brain stem and cervical spinal cord exit. When you have achondroplasia the foramen magnum is compressing the brain stem and spinal cord. Symptoms of narrowing include apnea the cessation of breathing and cervical myleopathy. C-T scans and MRI scans are done to examine the size of the infectious foramen magnum. A neurosurgical procedure called a foramen magnum decompression is executed to alarge foramen and alleviate further symptoms. Adolescents are at risk of getting lumbosacral spinal stenosis. The lumber spinal cord or nerve roots become compressed producing nerosurgical symptoms. Initial symptoms including weakness, tingling, and pain of the legs. Pain usually alleviated by assuming a squatting position.
In the book Their Eye’s Were Watching God, Janie the main character has a weaker role. Oprah strengthens Janie’s character when she makes the movie. “Women are not only considered the weaker sex but are fundamentally defined by their relationship to men” (Theme). In the book Janie has the weaker role. When Oprah makes the movie, Janie’s role significantly increases. Janie does things in the movie like saving Tea-Cake from drowning. In the book Janie actually needed saving from the flooding water, and Tea-Cake saved her. Oprah makes Janie’s character strength look much greater than it did in the book. In the movie Janie goes with Jody to buy more land for the town. Zora Neale Hurston’s version of this scene went a different way. Janie did not accompany Jody in the book when he went to buy land. Oprah strengthens Janie’s character by making her look like she has a role in decision making. The book shows Janie as not being an equal, but Oprah changed that when making the movie.
The Cuban missile crisis was a major turning point in American history. It sparked conflict between two of the most powerful countries and almost led to possibly the most horrific war ever. This point in American history also caused long lasting tension between the United States and Cuba and posed as the most terrifying 13 days in United States history.
The Cuban Missile Crisis was not only the tensest confrontation between these two nations; it was also the most controversial. There have been many different theories as to why the Soviet Union set up nuclear-armed missiles in Cuba in the first place. One theory suggests that Stalin’s successor, Nikita Khrushchev, placed these weapons in Cuba because he felt endangered by the United States’ nuclear missiles in Turkey, which were a threat to the Soviet Union. Another theory proposes that Castro feared for another US invasion in Cuba, thus enlisting the help of their communist allies. Since the unsuccessful attack at the Bay of Pigs, Castro feared for another invasion, perhaps a more successful one of Cuba. But nonetheless, the Cuban Missile Crisis proves to be successful in which we avoided a nuclear war.
Over time, there has been growing gap between criminal policy and criminology (Garland & Sparks, 2000). Despite the criminal knowledge and expertise academic criminologist possess, their advancement or role towards creating crime policy has not been immense (Garland & Sparks, 2000). While various governments have introduced mandatory minimum and more lengthy sentences for offenders, there has been a lack of strategic criminological advice and knowledge when developing these policies (Garland & Sparks, 2000). This lack of criminological influence when creating and imp...

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.

People with ocular albinism, which only the eye lacks melanin pigment, while everything else appears normal. People who have this have a variety of the eye disorders because of the lack of pigment impairs normal eye development. These effected are extremely sensitive to bright light. Treatment for ocular albinism includes the use of visual aids and surgery for strabismus.
The images formed on the two retinas are so unlike that they cannot be blended in the brain. Thus, a double image is perceived. The condition is known as diplopia, or double vision. Prismatic lenses are prescribed to correct this defect.Imperfections in the cones of the retina, resulting from heredity or disease, cause defective color vision. This is known as color blindness, or Daltonism. In total color blindness, everything appears in shades of gray.
