Functions Of Human Sensory Biology - 1631 Words

Sensory Biology Lab 6 Name: Dominic Siaw Biology 132 T.A: Marian Wahl Date Performed: 4/7/15 Date due: 4/14/1 Abstract In this laboratory students will perform various experiments to demonstrate various properties of human sensory biology. Students worked in pairs and performed 5 experiments. These experiments were based on touch receptors, temperature receptors, two point discrimination on the skin, locating distance from the fovea to our blind spot and measuring visual activity. T-test was performed and the results explained that there is no significant difference in how the body adapts to external stimuli. Introduction Sensory Biology is being able to perceive stimuli from the environment. The most common†¦show more content†¦Examples include eyes, nose and skin. The eyes are the main sensory organs being tested in this experiment. Eyes allow us to detect visible light which is reflected on images and allows us to see them. (McMillan 35) In this laboratory, an experiment will be conducted to explore the human senses. Most importantly the senses of touch. Various parts of the body will be tested to see how the body adapts to external simuli. These external stimui will be a coin touch, temperature and a touch from a two point discrimination. Also the ability to read from afar will be tested using the Snellen examination chart. Experimental Procedure The first experiment was an exercise based on adaptations of touch receptors. One student obtained a coin and a stop watch. The other student was the test subject. The test subject placed his/her palm-down on the desk. The test subject closed their eyes and a coin was placed on the back of the test subject’s hand (lower side of right most knuckle) and the stop watch was started. The clock was stopped when the test subject stopped feeling the coin. The time was recorded. The same procedure was repeated but during these times the coin was placed at 4 different locations of the hand. The time for each adaptation was recorded. This test was performed twice for each location and time for each adaptation was recorded. The T-test was then calculated to see if there is a statistically

Emancipation And The Historical Memory Of Reconstruction...

Emancipation and the Historical Memory of Reconstruction EricR.Jackson Northern Kentucky University Department of History and Geography Eric R. Jackson, associate professor of history and director of the Black Studies Program at Northern Kentucky University, received his BS from Ball State University (1988) and both his MA (1992) and doctorate (2000) from the University of Cincinnati. He is known for his publications in the fields of African American history/studies, early American history, and race relation studies. After the ratification of the Thirteenth Amendment and into the Reconstruction era, African Americans struggled to become equal citizens of the nation and produced a number of important and remarkable leaders who demonstrated to a rapidly changing and complex society that they could vote, hold political offices, and legislate effectively. However, the bitterness and regular acts of violence toward African Americans that characterized most of this period has caused many Americans to disregard or totally erase from their collective memories this most important period in the nation?s history. This article discusses more fully the historical memory of Reconstruction. The American Civil War (1861?1865) ended with a decisive victory for the Union.

Importance of Self-Esteem free essay sample

Self- esteem is an important part of life. Without strong self-esteem we are not at our full potential. We need strong self-esteem to have the confidence to do many tasks. The way others perceive us has an effect on our self-esteem as well as how we perceive ourselves. In order to have good self-esteem, we need others to be encouraging and communicate in a positive way. We also need to build our own self-esteem by realizing we need to be our self, not what others necessarily think we should be. Negativity from others only lowers our self-esteem and makes us less confident. We need confidence in order to communicate well with others. As I ponder on my self-esteem, I feel I am very confident in most areas but really lacking in others. An area that my self-esteem is lacking is speaking in front of a group of people or having a conversation with someone who is not very talkative. We will write a custom essay sample on Importance of Self-Esteem or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page I am normally a very talkative person but when it comes to communicating in the two situations mentioned above, my confidence goes out the window, so to speak. A perfect example of my problem is an Art class I recently took. My assignment was to do a painting by a certain artist and a presentation board on the artist. I was to get in front of my class and do a three to four minute presentation on the artist. I was very anxious from the day I received the assignment until the assignment was finished. Three or four minutes in front of a group of people seemed a life time to me because I do not have confidence when it comes to speaking in front of a group of people I know, much less a group of strangers. I felt I had done my best and my work was good. I felt like I had an A on the project but the anxiety would not go away. When I entered class the day of my presentation, I was shaking like a leaf. When my name was called to do my presentation matters only got worse. I got in front of class and forgot what I wanted to say, which did not matter because I could barely speak. Thank goodness, my art instructor started raving about how well I had done on the painting and the presentation board about a minute into the presentation. He said I did so well I did not have to talk about it; otherwise I would have had problems getting through the presentation. I received an A for the project. I was teased by classmates that I was the instructor’s pet because he kept on and on about how good my work was during the semester. I had to do this one more time in that class and tried to convince myself it was no big deal and I had obviously done a great job according to my instructor, but it was not any easier the second time around. Having the confidence to speak in front of others is an obstacle that I cannot seem to overcome. Being able to communicate well helps one to build self-esteem. I feel my problem with lack of confidence when speaking or communicating is due to lack of communicating and voicing my opinion at a younger age. At the time I was growing up, youngsters were not expected to give their opinions to their peers. My grandfather felt children should not give their opinion on any subject. Also, during school age, certain school mates thought they were better than others and made fun of anything the ones who were not in their group said or did, so I did not say much hoping that would stop the negative remarks. I feel their goal was to make students who were less fortunate feel less of a person, as well as to boost their egos. The lack of using proper speech also plays a part in my lack of confidence when talking to groups who I feel expects me to speak properly. I have heard many comments on how people in this area of Kentucky talk. Some say they love to hear us talk. The comments are not necessarily meant to be negative, more so teasing, but they are stuck in my mind when communicating with others who speak in a proper manner. I feel the lack of being encouraged and communicated to positively when speaking plays a role in my low self-esteem when communicating with others.

To What Extent Was The French Revolution Caused By Economic Depression

To What Extent Was The French Revolution Caused By Economic Depression In June 1789 the French revolution had begun. For the next five years there would be bloodshed throughout France, the country was going through a radical change, the change in sovereignty and the failure of the constitutional monarchy being two examples of this. But to what extent was all this caused by economic distress? Before being able to answer the question, one would have to establish the definition of economic distress it could be defined as the misery people (especially the peasantry) faced due to low income and tax inflation or the misery that the entire country was in due to the enormous debts, which had accumulated due to the wars, which were fought. The economic situation was only one of the elements that caused the people to question the monarchy in pre-revolutionary France. France was in great debt and almost bankrupt but this did not stop them from fighting wars. The debt an economic problem turned into a social one, when the peasants were taxed heavily in order to p ay for the debt, this caused them to question greatly their position in society and the effectiveness of their monarchy. Drought and other natural disasters ruined crop production, causing food prices to rise dramatically. With taxes rising and prices too, peasants were living in famine and in poor living conditions. The enlightenment was able to inspire revolutionary thoughts within the people. People began to abandon their beliefs in divine right and focused more on the thoughts of equality and society being run for the benefit of all. The economic situation only made people realize other problems concerning politics and society. A revolution (The complete overthrow of an established government or social order by those previously subject to it) would mean complete reform of political, ideological and economical beliefs, so for such a drastic change to be necessary there would need to be problems in all of these areas to begin with. In Pre-revolutionary France there were three estates - the first estate (clergy), the second estate (nobles) and the third estate (bourgeoisie, peasantry and urban workers). Most of the clergy came from noble backgrounds, as it was usual for the youngest sons of wealthy families to join the church in order to share its wealth. The churchs wealth came from tithes (a proportion or the each years crop paid to the church by landowners) and the vast amount of land that it owned. They clergy were exempt from taxes; instead they negotiated a don gratuit with the king. The don gratuit was an annual payment to the crown and was always much less than what would have to be paid in normal taxation. The church had a great deal of power too as the state religion was Catholicism, it was their duty to spread to ideas of divine right. The second estate was by far, the wealthiest and most powerful. They were exempt from paying direct taxes (until the 1749 vingtieme when they still paid less than they would have done if they were from the third estate) and doing military service such as the corvee (forced labour on roads) and made their money through the land they owned (between 15% and 25% of all land in France). They also receives seigneural (feudal) dues which were fees that the peasants were obligated to pay in order to use the lords mill, oven, wine press, breeding stock, death taxes, inheritance taxes and sale-of-property taxes. The third estate was made up of three parts; the bourgeoisie, who were the wealthiest and most educated part of the estate, many of them being financiers, landowners, doctors, writers and civil servants. It was also possible for wealthy bourgeoisie to buy venal offices to become nobles (however, most ennobling offices requires at least two generations of owners before nobility could be bought. The other part of the estate was the peasantry. It was the least wealthy and most numerous (85% of the French population lived in the countryside and most wer e peasants). Many of the peasants were laboureurs (people who grew enough food to feed themselves, these were the people who found it especially hard when
