Paul Fitts’ was the first to discover the relationship between the speed of movement and accuracy requirements. This has become one of the most fundamental principles of motor control. Fitts claims a relationship between task difficulty and movement time. He quantified task difficulty as “index of difficulty” which consists of the ratio of twice the amplitude over width of the target (2Amplitude/Width). This relationship states that when movement amplitude decreases or when target width increases movement time is shorter (Fitts, 1954). Fitts found that the relationship between amplitude and width was given by the equation: MT= a + b[log2(2A/W)]. The empirical constants a and b represent the y-intercept and the slope (Schmidt & Lee, 2011).…

This experiment focused on metabolism and biochemical tests. The goal of performing these tests was to differentiate microbes from one another and to compare how metabolic and biochemical processes differ from species to species. The tests performed include: the Fermentation of Sugars Test (sucrose, glucose, and lactose), the Urease Test, the Fermentation of Lactose Test, the Sulfide Indole Mobility (SIM) Test, the Nitrate Reduction Test, the Protein Hydrolysis Test, the Catalase Test, and the Cytochrome Oxidase Test. The microbes that were tested during this lab were: Escherichia coli, Bacillus cereus, the unknown, Proteus vulgaris, Staphylococcus epidermis, Enterobacter aerogenes, the control, and Pseudomonas fluorescens. The microbes tested during these various tests were looking for which would: reduce sulfur/produce sulfate, produce indole, or possess motility, reduce nitrate, and contain protease, catalase and oxidaase.…
Life has its way of getting so crazy to the point where it makes people want to escape their life and head off into the wild. Chris McCandless was no stranger to this, in April of 1992, McCandless began what he called his “great Alaskan odyssey” (Krakauer 203). McCandless left everything he knew behind and wondered off into the wild. People ask what makes one want to leave everything behind and just live off the country. Looking at McCandless’s motives for heading off into the wild, it makes sense to at least try.…
The topic of Source One is how explorers and colonists of the New World took part in horrific, illegal events to colonize the foreign lands, but yet they were not the ones who suffered from these events. This phenomenon is portrayed in the source through the image of a wanted poster for Christopher Columbus, where Columbus is wanted for several offences including: genocide, racism, initiating the destruction of a culture and rape. The poster also goes on to state that the reward for Columbus is “500 years of tourism”. The reward symbolizes how despite the atrocities that the explorers and colonizers took part in, they would be remembered throughout history for their accomplishments and not the horrendous events that brought them to those successes. The illustrator’s perspective on the source is the idea that colonizers of the New World were…
A research study entitled, Exploratory Investigation on the Hypoglycemic Effect of Abelmoschus Esculentus in Miceconducted was conducted by John Ray T. Perez et al (2013). Their paper made an exploratory investigation on the hypoglycemic effect of a common food item known as ―okra‖ or Abemoschus esculentus (EA). Six (6) mice were randomly selected and grouped into 2 groups and were given extracts from the fruit of Abelmoschus esculentus (EA)/okra which was chopped into three pieces and was soak in 250ml potable water overnight. 1st group is the Control Group and the 2nd group is the Treatment Group. Average results of the two (2) groups are determined and recorded upon conducting this experimental research. The Control Group has an average result of 94mg/dl in the 1st test, 99mg/dl in the 2nd test, 94mg/dl in the 3rd test, 101mg/dl in the 4th test,…
Museums bring history and culture to life by allowing individuals to gain unique hands on experience that is different from learning from textbooks or television. One can never know the reality behind certain artifacts and art until they see it for themselves. The perception of viewing a multitude of replicas and pictures such as the Mona Lisa can be dramatically different from witnessing the painting up close. The interactive experience allows one to engage and immerse ourselves back into time to learn about the truth of different cultures and traditions. The intent of museums is not purely to enthrall historians and scholars, but to create an environment which is welcoming to all individuals. While historians argue that museums…
In her article, author Katy Waldum succesfully dismantles Bu's research becuase she shows that thier is no scientific proof to prove Bu' research. That first born girls are leaders. Waldum shows evidence, "Alfred Adler, a student of Freud, pioneered the idea that firstborns seek out leadership roles, delight in rules and order, and value achievement; that lastborns tend to be charming, popular, and spoiled; that middle children -- yawn, who cares?; and that onlies can be both mature and dependent." This evidence shows how this is an idea presented and has gone through many people. Without real scientific proof of geniticaly bieng true. Also she proves by sending Bu's research to a University. The University siad "New research from scientists at the University of Essex, though, uses multilevel modeling techniques to overcome these hurdles, and the results suggest that birth-order effects are more than just a methodological illusion." So the scientists viewed her research and they clearly state that birth order effects are not true. This is just an idea people have heard and have believed. They have been blinded by the truth behind that birth order idea and dismantels Bu's ideas.…
Sojourner Truth in her speech, "Ain't I a Woman?" demonstrates that she's tired of inequality and fights for women's rights by having comebacks to the white men that don't think negro women like herself should have rights. In Malala Yousafika's interview, she views education as a gift and feels girl should also have the right to go to school. Both of these women feel women are as capable as men. Sojourner and Malala both express defiance against the law, show persistence for what they are fighting for, and fought morally for women's rights.…
Now in our society, the demands and expectation for students to have a higher education and be more advance has elevated. Students should be able to mastered their basic course like Math and English which leds to the question whether Common core should be considerate in student’s education from K-12 grades. Common core develop a set of standard that every students should exceeds or at least met. This allowed the students to see where they are placed and what they needs to improve on. However, many people, especially parents oppose the idea of Common Core. They dislike the facts that parents ’t able to help their child who is struggling on their homework. The debate about this issue has been getting hotter ever since the state education chiefs and the governors had developed the Common Core.…
The focus of this article is the bias found in evolutionary and endocrinological studies. These studies serve the purpose of defining and tracing human nature through evolution and present times. Evolutionary studies address the description of human descent from primates. These studies seek to outline the sequence of changes and mechanisms of action that make up the evolution of humans from primates. The general theory of evolution is used to reconstruct history with facts and evidence from fossils and other remains. Endocrinology is the study of how hormones affect human anatomy and physiology, behavior, and cognition.…
Moral obligations can be seen a variety of different ways, depending on the person. Some may think it is a person’s moral obligation to submit to a law even if they believe the law is wrong. Others think the opposite, if a person believes something is unjust why would they follow it. Everyone has a different point of view and after reading The Scarlet Letter by Hawthorne, The Letter from Birmingham Jail by Martin Luther King Jr., Laws Scarlet Letter by Korobkin and Lyceum Address by Lincoln, it is important to follow ones conscience. This may seem unjust, but is it just to support an unjust law? This is where the controversy comes in, and why after reading these three types of literature, the idea of supporting something unjust is completely wrong and breaks down the justice system.…
In the face of adversity, the beliefs of an individual may be greatly altered, or even liquidated, leading to the lack of execution or bad behavior. Even if a person with strong beliefs and morals is put into a difficult and unexpected situation, they may completely and unwillingly disregard their beliefs and morals and act accordingly, or not at all. Around lots of people, when bystander apathy or diffusion of responsibility is present, the individual may be affected by it as well. In Night, Elie knew that his father was “on the brink of death, and yet [he] still abandoned him” (Wiesel 11). Elie had prayed to the “God in whom [he] no longer believed” to never abandon his father, yet at such a difficult time, he simply did it (Wiesel 97). In the Perils of Obedience, the subject, Prozi, first “[refused] to take the responsibility” because the subject was in there “hollering” (Milgram 23). Immediately after the Experimenter said that he was “responsible for anything that happens to him”, the Prozi simply said “all right” (Milgram 23). This proves that the majority of people in a difficult situation will simply wait for somebody else to take responsibility for any wrong doings, or lack of action at all. If the experimenter remained silent, Prozi would have immediately stopped, knowing all responsibility lay on him. In the face of adversity, anyone’s beliefs can be changed, either because the individual is dumbfounded and doesn’t know what to do, or because they know that the responsibility of something horrid, is not…
The people of America live in a country whose citizens are gifted with the system of Democracy where each person has their voice represented in decisions of the nation. The inherent responsibility of each voting age citizen of America is to research the positions and views of all candidates that represent them and then punch, mark, or press the space next to the candidate that they believe would best represent him or her. But not all Americans would care to look closely at the opinions of the election candidates especially in a race as highly publicized as the modern presidential elections.…
Do we contemplate language when thinking about the origins of racism? We most likely do not think about it since language and racism does not appear to be correlated. But aren’t they associated? Yes, they are associated in the sense that language itself can take the form of racism. It is essential to recognize language as one of the most influential contributors to racism in order to see the connection between them.…
