Lab Report On The And Light Control Group - 959 Words

Ratner Miller (1959) performed an experiment to show that earthworms would react to the illumination change in light being paired with food. In this experiment there are four groups being tested. There was an experimental group (EG), vibration control group (VCG), random-response control group (RRCG), and light control group (LCG). Group EG went through 130 trials with a 50 second interval in between each. Of the 130 trials the first 100 were conditioning and the last 30 were extinction. During the conditioning trials the vibratory stimulus (CS) was presented for 6 seconds. Then the light (US) was presented for 2 seconds after the first 4 seconds. A response occurring during the first 4 sec. of the CS, prior to the presentation of the US, was recorded as a conditioned withdrawal response. The extinction trials consisted of a 6 second vibration and all responses that happened in the first 4 seconds were recorded. Group VCG had 100 trials. This were done and recorded the same as group EG except that the US was not presented at any time. Group RRCG consisted of 100 trials for 4 seconds. These trials determined the number of spontaneous recoveries, where the CS and US were not presented during the trials. Then lastly group LCG was to determine if the US would cause animals to become sensitive to the vibration. This group went through 105 trials, 70 of them were light trials and 35 were vibration trials. The light was present for 2 seconds within blocks of 10 in the 70 lightShow MoreRelatedSouth Street Seaweed Report Essay706 Words   |  3 Pages South Street Seaweed Report Prasenjit Saha Chem lab 106 2/6/13 Spring 2014 Prasenjit Saha, Abdullah Sharif I.

Trump Supreme Court Nominee Kavanaugh - Free Essay Example

Sample details Pages: 3 Words: 805 Downloads: 8 Date added: 2019/08/16 Category Law Essay Level High school Topics: Supreme Court Essay Did you like this example? The headline for the article I have chosen is Daughter of CIA Assassin Paymaster Tries to Bring Down Trump Supreme Court Nominee. The main claim of the article is that Dr. Christine Blasey Fords accusation of her attempted rape by Supreme Court nominee Kavanaugh is actually false and that this is all a plot by the CIA to bring down President Donald Trump. It goes on to try to prove itself by claiming that Dr. Ford is actually the daughter and sister of CIA operatives and that she is actually teaching CIA tested brainwashing techniques at Stanford University. The headline of the article accurately represents the article, as it tells the audience what the article will be about. Also, there is no specific original source cited in the article or website for this claim. However, similar claims has popped up on the internet ever since Dr. Fords name became public, most likely, due to discontent by Trump and Kavanaugh supporters. The website that this news article was on is not from one of the fake news sites listed on The Daily Dot or Snopes, but confirmation involving the claim itself can be found on Snopes. Don’t waste time! Our writers will create an original "Trump Supreme Court Nominee Kavanaugh" essay for you Create order I was attracted to this article because of the claim in the headline. Being a woman, these kinds of claims of false sexual assault reports are concerning to me, because we are the ones most known to be prey to sexual assault and harassment. These kinds of claims would make future claims doubtful and therefore, detrimental to creating a safe society for women to thrive. It also casts a negative light on women in general, which would just fuel the gender inequality in this country. What amused me was that the notes at the end claim that the website is exposing the truth to Americans so that we wont be blinded, yet, the organization itself sounds like a cult of some sort. In addition, its claims that governments discredit them to further their own agenda backs that notion even more. Though, I do not doubt there are governments like that, if their information really was true, the media would have mentioned it before, yet it is denounced as a site that fabricates evidence to prove their c laims. Other Sources According to Snopes, this story about Dr. Ford being a part of a CIA plot is false. Dr. Ford is accused of teaching mind control to help the CIA and is linked by the CIA Internship program at Stanford. However, she not involved in the Internship program in any way. In addition, others try to connect her brother with the CIA and Fusion GPS. Yet, Dr. Fords brother only worked in a company that resided in the same building as three other CIA-operated companies and left years before the company worked with Fusion GPS. In conjunction, Politifact also debunks the claim that Dr. Fords brother works for or with the CIA. The third link theorists claim, was that Nick Deak was her grandfather. Not only is she a different person from her grandfather, and therefore wouldnt be the same person nor have the same interests, Nick Deaks only recorded child was a son named Robert Leslie. While her father is named Ralph Blasey Jr., and there is no one by that name on her mothers side of the family. Overa ll, the claim that Dr. Ford is a CIA operative is proven untrue by disproving the three main claims of the article. Conclusion/ Lesson Social media has developed into a wide array of connections with people separated by long distances and is able to carry news in seconds. And in this way, fake news is spread by unsuspecting people. Sharing and promoting a certain piece of news takes only a tap; fast, efficient, and easy. And because it has gotten so easy, people dont really stop to think or bother to search if something is true. The catchy title part of fake news is also contributed by the popularity chasers. Being popular has been a phenomenon for centuries, but it has not been as pervasive as now, with social media. Teens want to be popular even with other peers at the other side of the world, they might not have met before, and sharing catchy stories, true or not, is the easiest way. I personally, have never posted fake news, mostly because Im not usually on social media sites, even if I have accounts on them. However, my takeaway from this assignment is to always check the facts before you post something online and doubt everything you see. After all, even credible news sites make mistakes, the reporters are only human in the end. My second takeaway is that fake news is easy to create and most people do so for immediate personal profits with little care for truth or crazy occultists.

foolear A Fool for a King in William Shakespeares King...

A Fool for a King in King Lear In Shakespeares play King Lear, the main character, King Lear, is presented as a respected and powerful king. As the story progresses the king loses his power because of his own stupidity and blindness. The tragedy of this play is shown chiefly through the actions of Lear’s daughters, which lead to Lear’s bout with insanity, and through the words of the Fool. At the beginning of the play, King Lear appears as a powerful and well-loved ruler. He explains his intention to abdicate and divide his kingdom among his three daughters, giving the largest segment to the daughter who convinces him that she loves him most (Boyce 343). Goneril is the first to lie, Sir, I love you more†¦show more content†¦The king is very upset by Cordelia whom he loved best of all his daughters. Tragically, Cordelia, who truly loves her father, is disinherited, and the kingdom is divided between her two greedy sisters. Giving the land to Goneril and Regan is the first of Lears mistakes, for the selfish daughters do not love him as much as Cordelia does, but merely wish to have his riches. Goneril and Regan decide to control their elderly father so he won’t eventually caste them off as he did Cordelia. They begin to speak disrespectfully of him, referring to him publicly as the â€Å"Idle old man† (I.iii.17). They take steps to ensure that Lear lose any power that he still retains, the first step being to diminish the ranks of his followers: â€Å"What, fifty of my followers at a clap† (I.iv.300)? Lear had proposed to his daughters that he and one hundred knights would live for one month at a time with each daughter. When Goneril breaks the bargain, Lear laments, â€Å"How sharper than a serpent’s tooth it is / To have a thankless child† (I.iv.280-281). He then turns to Regan who is also adamant that he releases his knights. In despair, Lear cries, â€Å"Yo u see me here, you gods, a poor old man, / As full of grief as age; wretched in both† (II.iv.306-307). The great tragedy here is that, despite Lear’s generosity and his love for his daughters, both daughters betray him and neither is willing to shelter him.

The fool serves to show Lear how he is going insane, as well as to attempt to delay

Poem Classification free essay sample

In the Garden and The Snake According to Webster’s Dictionary classify means to put into groups systematically because of common characteristics or properties. In my preparation for this paper I looked for poems that had similarities. The two poems I chose to classify are In the Garden and The Snake, both written by Emily Dickinson. In the Garden describes observing a bird, offering a bird food, the bird flying away, and the art of a bird flying. The Snake describes a snake moving through the grass, a snake as being hidden or unseen, and the fear of seeing a snake. Emily Dickinson is known for writing lyric poetry. Lyric poetry is described in our literature text as â€Å"a short poem expressing the thoughts and feelings of a single speaker. A lyric is often written in the first person† (Kennedy, 2007, p. 427), as in the poems I chose. These poems can both be classified as lyric poetry because the writer is sharing her thoughts and feelings of watching a bird and a snake. We will write a custom essay sample on Poem Classification or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page In the Garden has many words that refer to nature: garden, bird, angle-worm, grass, beetle, ocean, butterflies. The only words referring to nature in The Snake are grass and acre. Even though The Snake does not have as many references to nature as In the Garden the title creates a picture of nature in the mind of the reader. Another similarity that I found in these poems is the way Emily Dickinson used her words to apply human traits or actions to nature. Examples from In the Garden: 1. A bird came down the walk: This verse makes the bird appear civilized or socialized 2. And ate the fellow (worm), raw. This verse refers to a worm as a fellow and suggests that a bird would normally cook the worm prior to eating it as a human would. 3. And then he drank a dew From a convenient grass, This verse resembles the human action of drinking from a straw. 4. And then hopped sidewise to the wall To let a beetle pass. These verses depict the human behavior of politeness. Examples from The Snake: 1. A narrow fellow in the grass But never met this fellow, These verses refer to a snake as a fellow, a term used to describe a person. . Occasionally rides; This verse makes the snake appear civilized, like riding a bike or in a car. 3. A floor too cool for corn. This verse suggests a snake lives in a house instead of in the outdoors. 4. The grass divides as with a comb This verse suggests that the grass parts as hair does. Emily Dickinson’s In the Garden and The Snake have several similarities as described above. I would classify these poems by author, lyric poetry, nature, and how the words us ed apply human traits and actions to nature.
