In lots of ways we human distinguished ourselves from other species, such as straight-walking, the invention of language, the use of tools, etc. We also have highly flexible hands – their versatility doesn’t fall short of a Swiss army knife. But you may have noticed at times that one of your hands is not nearly as flexible, or useful, if you want to put it that way, as the other. Typically the “better” hand we have is the same hand we use for handwriting, which in most cases is the right hand. It is also known that not only do people prefer one hand over the other, but they also have preferred feet, eyes, even ears. Again, the right side is favored. However, study on chimpanzees – specie that shares more than 90% of our genes, showed some preference in body usage but unlike that of a human it was never consistent: close to 50% of them use left side and 50% right (McManus 192). This makes one wonder if there is something special about human that makes us shift towards right-handedness, and that what the shift has to do with our other unique qualities.
The way our brain operates has always been more of a myth. A study on the relationship between hand preferences and brain functioning could lead us to better understand the developmental neurobiology of our brain. Finding the underlying mechanism of the cause of handedness not only satisfies our curiosity but also contributes to our knowledge of how we function as specie. It could lead us to explain certain illness and maybe group people into more categories. Finally, left-handers in history had been discriminated against and even today, in many countries and cultures the use of left hand is very unwelcome. A more scientific understanding of handedness will hopefully make people realize the difference between what is “right” and what is correct.
Therefore, I ask…...

The Moon We Left Behind

...The Moon We Left Behind How can we as a society turn our back on our space program? The author of this article shows his admiration for imagination, which came to life. Nearly 40 years ago the space program was put in motion. The thought of mankind walking on the moon astounded a generation of scientist. Some of his points on where we place priority are evident. How can we spend time and money on a space station that we share with the Russians and Chinese, and not try to still excel above the rest of our counter parts? This mission remains ours to maintain our status in the science history books. We are experiencing problems at an alarming rate such as disease, unemployment, war, etc. Why not invest in the future and accept what it could bring. Imagine how it could jump start the vast number of great minds that exist in our communities here in the United States of America. One thing we all should marvel at is the “beautiful, intricate, and complicated -- and ultimately, hopelessly impractical -- machine ever built by man: the space shuttle.” (p. 55) But now it has become a display at our museums. So if our nation can spend billions on stimulus, why not put monies in our future space programs for our advancement? Furthermore, through the missions to the moon has created a new profound consciousness of earth’s environmental precautions. We have become a society that is deep into extra-terrestrials now more than ever before and why stop now? The picture of the blue......

No Child Left Behind

...Kaitlin Margaret Norris Kessler April 16, 2012 Is There Really No Child Left Behind? The No Child Left Behind Act, also known as NCLB was put into affect in 2002 by President George W. Bush. This law affects how students learn, the tests they take, and the way teachers are trained. It’s stated goal is to close the achievement gap between minority and non-minority students, between the disadvantaged and the advantaged, and between those living in poverty and those that are wealthy. After given a standardized test every year, the school is required to take different actions if their school does not improve each year such as directing a chunk of it’s funding to teacher development, giving students the option to transfer, changing it’s curriculum, or having the school shut down altogether. My claim is that we should adjust or amend the No Child Left Behind Act. No Child Left Behind’s attempt to narrow achievement gaps by ensuring that all children receive a quality education is admirable, but it is hardly realistic. Teachers would have to devote their entire time to teaching specifically just math and English. By doing that they block out any other subjects such as science, history, art, or any other important elective or subject. We should adjust the law by having less harsh punishments that way the students and teachers are not constantly stressing, and most importantly because we want to keep the students from doubting themselves academically. Some people may......

...Left Versus Right Brain And The Impacts Learning Human brain has two hemispheres with different function and each has an impact in human learning. The left hemisphere The element of human linear reasoning and language is performed by the left hemisphere. This means that it is the part of the brain responsible for things as grammar and vocabulary (Kalat, 2009). With linear reasoning, this simply gives an added advantage of numerical computation to the persons with the left brain part being dominant (angelfire, 2011). The difference in students’ ability to solve mathematical calculations is visible as students with dominant left hemisphere are associated with accurate and precise calculations when it comes to solving calculation issues (Paradiso, Bears & Connors, 2007). When it comes to numerical comparisons, and estimations, such students are also observed to have a higher hand in accuracy and exactness.In addition, where the left brain hemisphere is dominant, the student is characterized by better memory and retrieval of direct facts (angelfire, 2011).This means even in exams and tests based on curriculum, such people are in a better position to pass as they can fully and clearly understand instructions as well as retrieve what they have learnt easily and accurately (Paradiso, Bears & Connors, 2007). Talking of accurate calculations and estimates means better reasoning and number skills. Most of the time, such persons are good logical or sequential thinkers......

No Child Left Behind

...No Child Left Behind Stephanie Smith EDU623: Introduction to Teaching and Learning Instructor: Benjamin Kirgan February 4, 2013 In 2001, the United States government enacted what we now know as the No Child Left Behind Act of 2001. This education act was designed to ensure that no child regardless of economic status, or race would all receive the same high quality education that they deserve. The No Child Left Behind Act main focus was accountability for schools. Each state had to follow strict standards and if they did not meet those standards each year they would be required to correct the areas where they failed and in a timely manner or lose funding from the government. The No Child Left Behind Act also requires that teachers must be “highly-qualified”, this means that teachers are required to pass state exams and have a minimum of a bachelor’s degree to be a teacher, they must also demonstrate their abilities to teach in the subject they are hired for. There are many views on this subject but I feel that the No Child Left Behind Act is an important part of our children’s educational process but needs some improvement. I firmly believe that all children deserve a quality education and that schools get treated differently based on the neighborhood that they are in. All schools should be treated equally and each school should have the same books and equipment as to make them equals in the educational process. Many people feel......

The New Left Movement

...The New Left and Students for Democratic Society emerged in 1960. They were a group of young, highly educated and highly motivated students. The SDSers came from very privileged and political backgrounds. They were definitely not your average teenagers. The members of SDS were very concerned with the state of the country and government. They wanted to end poverty, eradicate racial injustice and make the world a better place for everyone. When they first started out, the party was very efficient and organized. As the decade moved on, however, the party’s ideologies and political stance changed. They began to split over political beliefs, drug use and tactics. I intend to map out Doug McAdam’s political process model to determine where they went wrong and ultimately failed with their anti-Vietnam movement. The political process model states that in order to start a social movement, three things must occur. They are; structure of political opportunities, use of indigenous organizational strength and realizing cognitive liberation. The SDS started out on the same page, working to support the Civil Rights movement in the early 60’s. They published the Port Huron Statement in 1962. “They wanted a society based on participatory democracy governed by two aims; first, that individuals participate in decisions determining the quality and direction of their lives, and second, that the society be organized to encourage independence and to provide for such common participation”......

Left-Handed Verses Right-Handed

...The Difference Between Being Left-Handed and Right-Handed About 90 percent of the world’s population is right-handed and only 10 percent is left-handed. It is exceptionally rare for a true ambidexterity. Most left-handed people develop some mixed-handedness by living in a world where most everyday objects are for right-handed people (Balter, 2009). Balter says “one researcher hot on the trail of these issues is Natalie Uomini, an archeologist at the University of Liverpool in the United Kingdom” (2009). Uomini states that handedness does not mean that one hand is more dominant over the other. She rather says that “both hands have different but equally important manual dexterity whereas the left hand might perform the more mundane but nevertheless crucial role of supporting an object” (Balter, 2009). Most children begin to emerge between the ages of seven and thirteen months and are well-established by age three (Balter, 2009). When figuring out when such consistency arose in humans is not an easy task. In small number of cases, it is possible to detect signs of handedness in early human fossils by the size of the shoulder and arm bones. There is a clear destination as indicated by the deeper bone insertions of the deltoid muscles in his clavicle and the greater length of the ulna (Balter, 2009). Uomini found out that even though hand bias may be hard to detect among early humans, there is clear evidence from the large number of Neandertal skeletons. The Neandertal......

No Child Left Behind

...The No Child Left Behind Act of 2001 is a United States Act of Congress that was originally proposed by the administration of President George W. Bush immediately after taking office. The bill, shepherded through the Senate by Senator Ted Kennedy, one of the bill's sponsors, received overwhelming bipartisan support in Congress. The House of Representatives passed the bill on May 23, 2001 and United States Senate passed it on June 14, 2001. President Bush signed it into law on January 8, 2002. The purpose and mission of the No Child Left Behind Act is to eliminate the achievement gap that exists between groups of students within our nation's schools. A glaring disparity exists in the achievement of Black, Hispanic, and students living in poverty when compared to white and more affluent students in the subjects of reading and mathematics. In 2003, 39 percent of white fourth graders scored at the proficient level in reading, while only 12 percent of Black students and 14 percent of Hispanic students scored at the proficient level in reading on the National Assessment of Educational Progress, also known as the "Nation's Report Card." No Child Left Behind stated President Bush's unequivocal commitment to ensuring that every child can read by the end of third grade. To accomplish this goal, the new Reading First initiative would significantly increase the Federal investment in scientifically based reading instruction programs in the early grades. One major benefit of this......

No Child Left Behind

...Professor Weslea Bell Erica L. Smith In 2001 President Bush presented the “No Child Left Behind Act of 2001”. He wanted to emphasize equal access to education and establish high standards and accountability. While in office, President Bush intentions were good however the Act itself has raised many issues and concerns with parents. Even though we all share the common goal, which is to better educate our youth, we must look more into depth regarding the pros and cons of the “No Child Left Behind Act”. The Act hinders our children, effects the ethics and morals of the school system, and our economy (Eugene Hickok, 2002). The thesis statement is the argument of demands of the reform “No Child Left Behind” have resulted in insufficient provision and implementation of services for special needs students in “failing” schools. The “No Child Left Behind Act” affects many, but perhaps the most affected are the children. The law was enacted to improve our children’s academic achievement, yet it has hindered them. Our children go to school 180 days out of the year and in those days they are expected to learn the necessary tools to help them be successful in the next grade level and in life. The Act raises concerns because it allows children to be promoted to the next grade level without meeting the requirements of the grade level they are currently in. This along is a major problem because how can we expect our children to master any grade level and they never mastered......

No Child Left Bihind

...EDUCATION Did No Child Left Behind Work? By Lanae Erickson Hatalsky and Stephenie Johnson | Published: 02/06/15 Are we about to snatch defeat from the jaws of victory? For the first time in more than a decade, Congress is moving forward on reauthorizing the Elementary and Secondary Education Act—known in its previous iteration as the No Child Left Behind Act of 2001 (NCLB). Voices on both sides of the aisle have proposed major changes, including tossing the annual testing requirement for kids in grades 3 through 8, as well as repealing the accountability measures that have allowed the federal government to require states to address failing schools and yawning achievement gaps. There is no doubt that NCLB has problems that should be addressed in a new reauthorization. But before we throw out NCLB and rewind to the policies of the 1990s, we should examine what, if any, effect the era of accountability ushered in by President George W. Bush, late Senator Ted Kennedy (DMA), then-Congressman (now Speaker) John Boehner (R-OH), and retired Congressman George Miller (D-CA) has had on student achievement. As we outline below, even a cursory look at the data makes clear that after decades of stagnant scores, the last 15 years of accountability have brought measurable gains for students across the board, and the biggest gains during the NCLB era have been concentrated among the kids who needed them the most. While there are still serious problems to confront and......

Left Realism Speech

...Libertarian- Left Realism On behalf of the great Libertarian party, we would like to express our proposals for tackling crime. As a collective we take crime seriously and realise that it needs to be at the top of our agenda. If you elect us here are several of the solutions for crime we will introduce: Firstly we will employ more ethnic minority police officers. This is because there has been an increase in crime since the 1950s which mostly affects disadvantaged groups. This country needs a lot more role models for disadvantaged groups such as ethnic minorities. A solution to this problem which we are going to use is to employ more ethnic minority police officers. This is so young people have positive role models and we can stop the negative stereotype. Secondly we will install more CCTV cameras around the country. As we recognise that many deprived communities do not have the required surveillance to feel safe in their own societies. Providing more CCTV cameras will enable us to make sure that criminals from all areas do not have the upper hand. Thirdly we will integrate police officers into our societies through community policing. We believe that if police officers are embedded within the communities they serve, instances of racial profiling, and excessive use of violent force would be less likely to happen. Community policing will help to facilitate greater conversation, interaction, and friendliness between police officers and residents. Lastly we will......

Left Behind

...Left Behind Misty Dennis GEN499: General Education Capstone Leslie Ruff October 11, 2015 The heartache of losing someone dear to us is a pain that most of us will unfortunately experience at some point in our lives. Comforting someone who has lost a loved one is not an easy endeavor, as finding the right words to ease someone’s pain is no easy feat. Now, imagine comforting a mom or dad, sister or brother, spouse or child of someone who intentionally took their own life. Not only does the family and friends of the suicide victim feel the shock of loss, but also they may feel that they failed the victim in some way, did not see the signs, and feel guilt that they should have seen this coming. Coupled with their own guilt, they may also shoulder the burden of the guilt of others, as society places blame on the survivors for not helping the victim deal with emotional or physical problems that may have led to the ultimate untimely death. As healthcare providers, it is important to not place blame, and to help the survivors find a way to deal with the loss, as well as the guilt. It is imperative for the healthcare provider or clinician know how to react when faced with this situation, as their role could have a lasting impact on those that have been left behind. PROBLEM There are so many people these days taking their own lives. According to the American Foundation for Suicide Prevention an American commits suicide every 12.95 minutes, and more than 1.5......

On the Left Side

...On the Left Side Sins are inevitable. People make sins every day without them even knowing it. But when they do, they tell their sins to God and God will forgive them. That is not how life works to all people who believes in God. God may see past a sin but that is not the case for some people. Some people cannot see past a sin and that is what we see in this short story from 1991 On the Left Side. This short story deals with almost a whole town of hypocrites who has supported a project, which was to send someone to Burundi, some state in Central Africa, to set up and run a medical mission. The choice landed on Sister Philomena O’Halloran. After twenty years of work, she sent a young African back to the hometown, Conn, in Western Ireland, and the reception was shocking as they easily could see, from his looks, who the mother was. The narrator is a woman who has also sinned by getting a baby with a man outside a marriage, just as Sister Philomena O’Halloran. “The right side of the church is filled to bursting, while only ten people – myself and nine other sinners – sit on the left.” (p.1, l.2). After Father O’Rourke and as good as the rest of Conn had dropped their investments in Sister Philomena O’Halloran’s mission, the narrator were still managing to raise money, in a fond she had raised herself, and sent them to Sister Philomena O’Halloran, but it were not as much as it used to be. The narrator is mad on the way Father O’Rourke is keeping Friday outside and how Friday is...

Bush in 2001. The legislation funds a number of federal programs aiming at improving the performance of U.S. schools by increasing the standards of accountability for states, school districts, and schools, as well as providing parents more flexibility in choosing which schools their children will attend. Additionally, it promotes an increased focus on reading and math .The intent of NCLB is that all children will meet state academic achievement standards to reach their full potential through improved programs .People who say No Child Left Behind has made schools better often cite the premise of the law because struggling students would be brought up to the level of their peers, students would get more individual attention and other supporters point to improvements in school performance, including test scores as the reason they think the act has helped schools (Armstrong, Henson, &Savage, 2009, p.72-73) . In addition, supporters say the law makes schools more accountable because NCLB has improved teachers’ performance by giving them guidelines for performance or by establishing new requirements for teachers.
