Visual Form Agnosia Essays -- Medical Research

Visual form agnosia is defined as the inability to recognize objects (Goldstein, 2010). To understand the basic concept of visual form agnosia, it is important to first understand that perception and recognition are separate processes. Perception is defined as the ability to become aware of something through our senses, and recognition is the ability to put an object in a group that gives the item meaning. When a person suffers from visual form agnosia, they are generally able to identify the item and distinguish parts of it, but are not able to perceptually accumulate every piece of the item in order to identify the item as complete (Goldstein, 2010). The following is a review of studies concerning the different aspects, theories, and characteristics in visual form agnosia. The brain is divided into two visual streams, the ventral and the dorsal stream. Goodale and Milner (1998) have suggested that the ventral stream is dedicated to processing vision for perception, and the dorsal stream for vision and action. On the other hand, there is a possibility that the processes in the visuomotor stream can provoke perceptual processes. The propose of the visuomotor stream is that it provides signals, which enhances the person’s ability to distinguish the form of the object. This study illustrated that stimulated perceptual development vanishes if the intended objects only have a difference in respect to their shape, but not width (Goodale & Milner, 1998). Emphasis has been placed on the disconnection of the dorsal and ventral streams, but there are also many associations between them, and the state of successful integration of their ‘complementary contributions’ can help humans with goal-directed adapted behavior (Goodale & Servos, ... ...

Diane Arbus

Diane Arbus was originally born Diane Nemerov on March 14, 1923 to David Nemerov and Gertrude Russek Nemerov. She was the daughter of a wealthy New York businessman. Her family owned Russeks department store on Fifth Avenue, allowing Dian a pampered childhood. As a member of a prominent New York family, she grew up with a strong sense of what was â€Å"prohibited† and what was â€Å"acceptable† in high society. Diane’s world was a protected one, with little adversity; yet this very lack of adversity made her feel as thou she was living in ungrounded world.As funny and different as it may seem, the ability to have a comfortable life was somehow painful for her. An extremely shy child, she was often fearful but told no one of her scary daydreams and nightmares. From what I gather her closest relationship was with her older brother, Howard. For Jr. High School, the seventh through the twelfth grade, Arbus attended Fieldstone School in the Riverdale section of the Br onx. At Fieldstone she became interested in public spectacles, rituals, and myths; ideas, which would later influence her photography work.Here she also devoted much of her time and energy to art class sketching, painting, and clay sculpture. During this period of her life, Arbus and several of her friends began exploring the city of New York. On their own they would take the subway, getting off in unfamiliar areas, Brooklyn or the Bronx. They would go out to observe and following interesting or unusual passers. At the young age of 14 Diane met her future husband. Allan Arbus, a 19-year-old City College student who was employed in the art department at Russeks, her father’s store. They say it was love at first sight for the young happy couple.Her parents obviously disapproved, as he was not of the same wealth class. However their disapproval only served to heighten Diane's conviction to marry him. Diane saw in marriage a way to escape from all that was restricting and oppress ive in her family life. In many ways, Allan represented the freedom she had been searching for. They were married, on April 10, 1941, with only their immediate families present. At the start of their new lives, to ease financial burdens her husband Allan supplemented his income by working as a salesman and also by doing some fashion photography.Diane Arbus soon became his assistant. World War II came and Allan was sent to a photography school near Fort Monmouth, New Jersey. Soon after Arbus relocated to nearby, Red Bank, and set up a darkroom in their bathroom. As a way to learn Allan taught her everything he was learning in school. May of 1944 came and Allan was transferred to another photography school in Astoria, Queens. By this time Diane was pregnant. She was having their first child, Doon Arbus, who was born April 3, 1945. During the 1940s however, Arbus briefly studied under photographer Berenice Abbott.Learning all she could about photography she and her, husband teamed up a s fashion photographers. Their first customer was her father’s business, Russeks. They were first published in the magazine May 1947 issue of Glamour. This would mark the beginning of a long association with (Conde Nast publishing) firm. Their forte was shooting models in motion. For some reason, the Arbuse’s despised the shallowness of the fashion and the magazine industry. Working in the fashion industry with all the glamour and glitz brought her lots of stress. During this period her only real joy was photographing friends and relatives.She would often wear a camera around her neck at friend and family events. On April 16, 1954, Diane became a mother for the second time. She gave birth to her second daughter, Army Arbus. Now in addition to her fashion work she was also photographing children. She would go out to Spanish Harlem in New York to photograph stranger’s children. In the 1950s she also found herself increasingly attracted to nontraditional people, pe ople on the fringes of normal society. This new avenue provided a release from the oppression felt in the fashion world.During this time of her life she also suffered from recurring bouts of depression. Due to her mental state in 1957 the couple decided to make a drastic change. He would continue to run their fashion studio, leaving her free to find and photographic subjects of her own choosing. Diane began attended Alexey Brodovitch's workshops at a New School. However Arbus found herself drawn to the work of photographs like (Weegee) Arthur Fellig, Louis Faurer, Robert Frank and, especially to the unusual pictures of Lisette Model. In 1958 Arbus enrolled in a class, Model was offering at a New School.It was during this period Diane decided, what she really wanted to pursue photographing â€Å"the different. † She saw her camera as a sort of all access pass, that allowed her to be curious, nosy, and to explore the lives of others. Gradually she overcame her shyness. She enjo yed the ability of going where she never gone before as she did as young child. She would enter the lives and homes of others and confronted that which she had never had in her own overprotected childhood. Her teacher Model taught her to be specific, that if you pay close scrutiny to reality it produces something fantastic.In her early projects, she undertook photographing what she referred to as â€Å"freaks. † She responded to them with a mixture of shame and understanding. For some reason she always identified with her subjects â€Å" the freaks† in a personal way. You could refer to Arbus' â€Å"specific subject matter† as â€Å"freaks, homosexuals, lesbians, cripples, sick people, dying people, and even dead people. † Like Weegee instead of looking away from such people, as do most of us, she looked directly at these individuals, treating them as a serious part of humanity.As a result, they opened their arms to her as one of their own making her work original and unique. In1960, When Arbus and her husband separated, her work became increasingly independent. During that period she began her series of circus images, photographing midget clowns, tattooed men, and sideshow freaks. Diane was frequently seen at Hubert’s Freak Museum at Broadway and 42nd Street, fascinated by the figures she saw. To build a repot she returned again and again until her subjects knew and felt comfortable around her. She also frequented the Times Square area, getting to know the thugs and bag ladies.Arbus’s style, was to pose her subjects, them looking directly into the camera, just as she looked directly at them. For her, the freaks were always more important than the picture. She said, â€Å"I don't like to arrange things; I arrange myself. † She was a firm believer that there were things in life everyone overlooked and no one would ever see, unless she photographed it. In the early 1960s Arbus began to photograph, nudists. She vis ited nudist camps in New Jersey and Pennsylvania, were she agreed to take her clothing off in order to be allowed to stay with them.This period was particularly productive for her, 1962 to 1964. It was during this period Arbus' won her first Guggenheim fellowship for a project on â€Å"American rites, manners, and customs†. Of Arbus' pictures three were shown in John Szarkowski's 1965 show at the MOMA, (Museum of Modern Art) â€Å"Recent Acquisitions†. There were two from her series on nudists and one of two female impersonators back stage. These honest images shocked and often repelled Viewers. Later her work was included, along with that of Lee Friedlander and Garry Winogrand, in Szarkowski's â€Å"New Documents urvey of 1967)† exhibition at the MOMA. The show, which opened March 6, marked the pinnacle of her career while she lived. It included some 30 examples of her work. Critics called her â€Å"the wizard of odds. â€Å", â€Å"the peeping Tom in all of us. † From 1966 on Arbus struggled with bouts of hepatitis, which often left her extremely depressed. In 1969, Allan Arbus, her life long partner, formally divorced her leaving her devastated. He married Mariclare Costello soon after the divorce. To cope with this difficult period Arbus photographed many influential figures of the 1960s: F.Lee Bailey, Jacqueline Susann, Coretta Scott King. Diane Arbus committed suicide in her New York apartment on July 26, 1971. In 1972, a year after she committed suicide, Arbus became the first American photographer to have photographs displayed at the Venice Biennale. Her show broke the attendance record set by the Edward Steichen's noted 1955 photographic exhibit Family Of Men which did include a photograph by the Arbuses of a father and son reading a newspaper, Millions of people viewed traveling exhibitions of her work in 1972-1979.In 2003-2006, Arbus and her work were the subjects of a another major traveling exhibition, Diane Arbus Rev elations. In 2006, the motion picture Fur, starring Nicole Kidman as Arbus, presented a fictional version of her life story. To this day her work continues to draw discushions and provoked controversy. Norman Mailer was quoted in 1971 as saying â€Å"Giving a camera to Diane Arbus is like putting a live grenade in the hands of a child. â€Å"

Egg in a Bottle Demonstration

The egg in a bottle demonstration is an easy chemistry or physics demonstration you can do at home or in the lab. You set an egg on top of a bottle (as pictured). You change the temperature of the air inside the container either by dropping a piece of burning paper into the bottle or by directly heating/cooling the bottle. Air pushes the egg into the bottle. Materials Peeled hard-boiled egg (or soft-boiled, if a yolky mess interests you)Flask or jar with an opening slightly smaller than the diameter of the eggPaper/lighter or very hot water or very cold liquid In a chemistry lab, this demonstration is most commonly performed using a 250-ml flask and a medium or large egg. If you are trying this demonstration at home, you can use a glass apple juice bottle. If you use too large of an egg, it will get sucked into the bottle, but stuck (resulting in a gooey mess if the egg was soft-boiled). We recommend a medium egg for most bottles. An extra-large egg gets wedged in the bottle. Perform the Demonstration Method 1: Set a piece of paper on fire and drop it into the bottle. Set the egg on top of the bottle (small side pointed downward). When the flame goes out, the egg will get pushed into the bottle.Method 2: Set the egg on the bottle. Run the bottle under very hot tap water. Warmed air will escape around the egg. Set the bottle on the counter. As it cools, the egg will be pushed into the bottle.Method 3: Set the egg on the bottle. Immerse the bottle in a very cold liquid. We have heard of this being done using liquid nitrogen, but that sounds dangerous (could shatter the glass). We recommend trying ice water. The egg is pushed in as the air inside the bottle is chilled. How It Works If you just set the egg on the bottle, its diameter is too large for it to slip inside. The pressure of the air inside and outside of the bottle is the same, so the only force that would cause the egg to enter the bottle is gravity. Gravity isnt sufficient to pull the egg inside the bottle. When you change the temperature of the air inside the bottle, you change the pressure of the air inside the bottle. If you have a constant volume of air and heat it, the pressure of the air increases. If you cool the air, the pressure decreases. If you can lower the pressure inside the bottle enough, the air pressure outside the bottle will push the egg into the container. Its easy to see how the pressure changes when you chill the bottle, but why is the egg pushed into the bottle when heat is applied? When you drop burning paper into the bottle, the paper will burn until the oxygen is consumed (or the paper is consumed, whichever comes first). Combustion heats the air in the bottle, increasing the air pressure. The heated air pushes the egg out of the way, making it appear to jump on the mouth of the bottle. As the air cools, the egg settles down and seals the mouth of the bottle. Now there is less air in the bottle than when you started, so it exerts less pressure. When the temperature inside and outside the bottle is the same, there is enough positive pressure outside the bottle to push the egg inside. Heating the bottle produces the same result (and may be easier to do if you cant keep the paper burning long enough to put the egg on the bottle). The bottle and the air are heated. Hot air escapes from the bottle until the pressure both inside and outside the bottle is the same. As the bottle and air inside continue to cool, a pressure gradient builds, so the egg is pushed into the bottle. How to Get the Egg Out You can get the egg out by increasing the pressure inside the bottle so that it is higher than the pressure of the air outside of the bottle. Roll the egg around so it is situated with the small end resting in the mouth of the bottle. Tilt the bottle just enough so you can blow air inside the bottle. Roll the egg over the opening before you take your mouth away. Hold the bottle upside down and watch the egg fall out of the bottle. Alternatively, you can apply negative pressure to the bottle by sucking the air out, but then you risk choking on an egg, so thats not a good plan.

Gender Inequality and Parenting - 804 Words

Most parents try to give their children equal opportunities regardless of their gender. But parents tend to be more protective over their daughters than their sons. Some parents say this is because females are an easier prey. Raising children with gender stereotypes is unfair and can lead to problems such as pressure and high levels of disobedience. Children feel pressured now because if they do not act according to their gender stereotypes or how society wants them to behave, they get shamed and humiliated for not following in society’s rules.As a parent you try to give your children the best, but sometimes that’s just not enough. While some parents think that their rules are equal to both their sons and daughters, these parents tend to put more pressure and rules towards their daughters. While some may claim this is necessary for safety, I believe that it’s unfair. It is true that danger and violence is easily targeted towards women and girls because of what so ciety considers â€Å"weak† but there is no question that parents are less lenient towards boys rather than girls. Society portrays women and young girls to hold a house hold together, cook, clean, watch the kids, etc. Most women and girls are not even expected to get far in education, and even some STEM field subjects like science, technology, engineering, and mathematics have always been a problem for women and young girls because these subjects are more male dominated.

The Marginal Propensity to Consume

Questions: a. Describe what is meant by the marginal propensity to consume (mpc) and give its formula. b. Assume that GDP rises from $550bn to $650bn. Assume that this results in the consumption of goods and services rising from $340bn to $400bn. What is the mpc? c. Assuming that the domestic mpc remains constant, what will the level of consumption be if GDP rises to $700bn? d. If Australian consumption of goods and services is $400bn, investment is $120bn, government expenditure is $150bn, exports of goods and services are $140bn and imports of goods and services are $145bn, what is the level of aggregate expenditure (E)? e. Given your answer to (d), and assuming that GDP is currently $650bn, what will happen to GDP? Answers: (a). The marginal propensity to consume (MPC) refers as division of a total increment in pay that a customer spends on the utilization of products and in addition services, in preference to save it. Moreover, MPC plays a significant role in order to calculate the percentage of extra income that is used on consumption. MPC is an important component of Keynesian macroeconomic theory (Bilbiie Straub, 2006). Along with this, MPC is ascertained separating the adjustment in consumption by the change in income. In addition, the formula is as below: MPC = C / Y In this formula, C indicates the change in consumption, whereas Y points toward change in income (Gnos, Rochon, 2008). Hence, the formula is helpful to calculate MPC in an accurate and an appropriate manner. (b). MPC represents the changes in income because of changes in consumption. In the given question, GDP ascends from $550bn to $650bn. Moreover, the outcomes in the consumption of goods and services are ascending from $340bn to $400bn. The MPC is calculated as below: MPC = Change in Consumption / Change in GDP Change in Consumption = $400bn - $340bn = $60bn Change in GDP = $650bn - $550bn = $100bn MPC = $60bn/$100bn = .6 As a result; by considering all the given data the MPC is .6. (c). If the domestic MPC remains constant .6 and the GDP rise to $700bn then the level of consumption would be: = $700bn/ (1-.6) = $700bn/ (.4) = 1750 (d).Consumption of goods and services = $400bn Investment = $120bn Government expenditure = $150bn Exports of goods and services = $140bn Imports of goods and services = $145bn The level of aggregate expenditure AE = C + I + G + NX (Hubbard, Garnett, Lewis, 2012). = 400 + 120 + 150 + (140-145) = 665 At this point; C = Consumption: The household consumption over a specific time period. I = Investment: The amount of expenditure towards the capital goods. G = Government Expenditure: The amount of spending by governments (federal, state, and local governments). Government expenditure can take in infrastructure or else transfers that may increase the total expenditure in the economy. NX = Net exports: (Total exports- total imports). (e). Given answer to (d), and assuming that GDP is currently $650bn, and then the GDP will rise instead of fall or stay the same. The main reason behind it is that, according to the expenditure approach, aggregate expenditure is considered as a major part of GDP calculation. For that reason, if the aggregate expenditure will increase then it will increase the GDP in an automatic manner (Hubbard, Garnett, Lewis, O'Brien, 2014). Moreover, expenditure method is the most common method that is used in order to calculate GDP in an accurate manner. The formula for its calculation is given as below: GDP = C + G + I + NX On the basis of the above formula, it can be said that, the expenditure method involves aggregate expenditure to calculate the GDP.

My Views on Patriotism free essay sample

Jose Luna Mrs. Peterson English 12, P. 2 1/21/12 Patriotism Many people think patriotism means supporting your government during times of war. I don’t believe that for many reasons. I think you can have patriotism and not support your country. I don’t think patriotism means supporting your government in times of war. A reason I am against this belief is because it is not always the same thing to be a good man and be a good citizen or patriot What if the government is doing something bad like telling us who to hate or you would be one of them. Would you hate them and be a good American or would you be human and ask why? This has happened before in the USA and is known as McCarthyism. I f you spoke out against the government you would be branded a communist. Eventually more and more people came to their senses and began to rebel against the government. We will write a custom essay sample on My Views on Patriotism or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Another Reason I don’t agree with this Idea is because what if our country was invading another for the wrong reason and killing thousands of innocent lives. I think a life is worth more than some resources. Would you stand be your government knowing its killing innocent people for a profit? A country that has done this is the USA, it has invaded many countries for it resources. My final reason is you don’t have to support your government to have patriotism. Patriotism is the love for your country. The government and the country are two very different things. The government is the way a place is governed. I believe we should always be loyal to our country and loyal to the government only when it deserves it. An example happened a long time ago in the time of the Aztecs and the Spanish Conquistadors. Montezuma (Aztec king)  was  stoned to death  by his  own people because he represented the he Represented the Agenda of White Spaniards Once He Was Captured. If Montezuma had not listened to the Spaniards then they would have supported him. In conclusion, patriotism does not mean supporting your government during times of war. To be a patriot all you have to do is love your country and be willing to sacrifice to protect it. We don’t have to support the government but we do have to defend it from threats including from an oppressive government.
