To Arms or Not to Arms Against Corcyra essays

To Arms or Not to Arms Against Corcyra essays Attention! Attention! Is it time for taking up arms or not? The Corcyraeans and Corinthians are debating here in Athens to persuade us on our participation in the upcoming war. Do we join Corcyra; the city that started the colony of Epidamnus, or do we join the original colonizing city of Corinth? To fully understand the potential of war, Athens must understand both sides and therefore we, Athens, will be able to decide on the stance we must take. Do we go to war with the Corcyraeans (those that have remained neutral in the past) or do we remain neutral as asked by the Corinthians (those that have served with us in the past)? Should Athens help defend the Corcyraeans even when they admit that they have failed to be part of any alliances in the past? As a colony that has been set apart by their own actions comes running when they cant even work out their own problems wants, nay, needs Athens help. The Corcyraeans stated to the Athenian assembly that they themselves chose not to have alliances by stating when a people that have not rendered any important service or support to their neighbors in times past (1.32.1). These representatives from Corcyra believe that their past isolation has helped their growth. Now once their growth has expanded beyond their ability to be able to control the interests of the government they come crying to us to help with the situation. These representatives even state that they can not fix the problem by stating: seeing our utter inability to cope wit them without foreign aid, and the magnitude of the danger which subjection to them implies, find it necessary to ask h elp from you and from every other power (1.32.5). Because of Corycras isolation from past political alliances, they have been put into a situation where they can not defend themselves and they must come crawling to Athens for assistance; and quite possibly survival from Corinth.

12 Amazing Full-Ride Scholarships You Can Win

12 Amazing Full-Ride Scholarships You Can Win SAT / ACT Prep Online Guides and Tips The full-ride Scholarship: the most mythical of scholarships that all students secretly (or not-so-secretly) dream of.Unfortunately, these scholarships are hard to come by, and they're even more difficult to win. Though many schools offer full-ride or full-tuition scholarships, there are also a handful of scholarships out there- run by independent organizations and even the government- that you can use at almost any school.Read on to learn about some of the most highly sought-after scholarships in the country. What Is a Full-Ride Scholarship? A full-ride scholarship is the unicorn of scholarships. It’s estimated that fewer than 20,000 students per year will manage to get one of these scholarships- that’s less than 1 percent of the students attending college! By far, the vast majority of these scholarships come from universities and colleges that are trying to attract top students to their campuses. Full-ride scholarships from private organizations that you can use at any school are even more rare. These scholarships cover not just tuition but also additional expenses, such as room and board, travel costs, and textbooks. Who Should Apply For These Scholarships? High school students who think they are the cream of the crop should apply for the scholarships listed below. You’ll see that some of them have specific requirements, such as race or location, whereas others are open to anyone. You should be at the top of your class (most of these scholarships are looking for students in the top 10 percent) and have high test scores.You should also have specific, strong examples of your leaderships skills, community involvement, and excellent character. Unsurprisingly, most of these scholarship applications will require you to do some writing, so make sure you're a strong writer, too. Finally, expect to need top-notch letters of recommendation from multiple sources. Top Advice for Winning a Full-RideScholarship Don’t put all your eggs in one basket. Even if you have the attributes mentioned above, there are going to be a lot of other students out there who have done just as well as you have. There are a lot more great students than there are full-ride scholarships, so you're not going to get one unless you're really lucky. You'll have a much better chance of winning scholarship money if you don’t try to get it all in one go. Think about your strengths, what you want to pursue in college, and your favorite activities, and go out and find several smaller scholarships to apply to. Though the payoff won’t be one lump sum, you’ll have much less competition and a far higher chance of success. 12 Fantastic Full-Ride Scholarships This list includes a dozen full-ride scholarships- offered by both private companies and the government- that you can use for many different schools.

The assassination John F. Kennedy Research Paper

The assassination John F. Kennedy - Research Paper Example F. Kennedy, though there are certain reliable evidences which point out to the action of a single assassin. The purpose of this paper is to analyze a murder-case of John F. Kennedy. First, it will highlight some biographical details about the president. Further, it will present the information about the assassination and the offender. Also, it will try to investigate the political goals behind the crime. John F. Kennedy was born on May 29, 1917 in Brookline, Massachusetts. He got a higher education at Harvard. After the graduation, Kennedy fought in a war having joined the U. S. Navy. In the period from 1947 to 1953 he served as a member of the U. S. House of Representatives from Massachusetts. In 1953 he worked as a senator for the same state (â€Å"John F. Kennedy†). While establishing the political career, he wrote a book about prominent senators named â€Å"Profiles in Courage† and was awarded a Pulitzer Prize for it in 1957. Then, in 1960 John F. Kennedy won the 35th presidential elections and became the youngest and the most favored President of the Unites States. He was also the first Roman Catholic to be chosen for this high post (â€Å"Life of John F. Kennedy†). During his presidency, J. F. Kennedy had to deal with several crises on the international level including the Cuban Missile Crisis and the creation of the Berlin Wall at the initiative of the Soviet Union leader which turned into the most powerful symbol of the Cold War. These events are often associated with the reasons of the President’s murder. However, John Kennedy accomplished great success in the U. S. foreign policy as well. His most remarkable achievements involve the Nuclear Test-Ban Treaty, the creation of Peace Crops and the Alliance for Progress with Latin America. He was also a great proponent of the Civil Rights Movement (â€Å"John F. Kennedy†). On November 21, 1963 John F. Kennedy went to Dallas, Texas, for the promotion of his election campaign.

Sustainability of Seafood Farms Essay Example | Topics and Well Written Essays - 500 words

Sustainability of Seafood Farms - Essay Example Today’s global economy has increasingly placed an emphasis on sustainability measures both as a means of improving the social environment and as a path towards cutting-edge innovative design. While sustainability has emerged in nearly all aspects of modern innovation, one of its prominent areas of influence is in the triple bottom line of fish farming. Triple bottom line has influenced sustainability through concerns with people, planets, and profits ecosystem ("Common terminology," 2009). In fish farming this approach has prominently been implemented through catching methods that do not harm the specific species long-term ability to reproduce or operate in a functional ecosystem ("Common terminology," 2009). Within this context of understanding there have emerged a plethora of methods wherein triple bottom-line approaches to sustainability has had strong impact on seafood farms. There are a number of concerns when investigating the sustainability approaches to fish farming. Among the most prominent overarching concerns are the notions of production, distribution, and consumption. Production refers to the amount of fish that can be acquired or ‘produced’ within a farming area during a specified period of time; this notion is important, as farmers must increasingly take sustainability measures into consideration or face continually diminishing production.

Nature vs. Nurture Essay Example for Free

Nature vs. Nurture Essay Over recent years the nature vs. nurture debate has been extensively discussed and researched. Should human characteristics such as intelligence, personality, behavior and ability be attributed to our genetics or our environment? One problem with this is how to pin a trait down to either an inherited or learned characteristic, or perhaps itÂ’s both. Are we to blame for our behavior or is inevitable due to our genetics? This question and others seems to be part of the controversy over the subject. Also, these questions play a factor in how to change and adapt behavior. Different techniques would be more effective depending on the cause of a particular behavior or characteristic. When analyzing the causes of behavior problems in children the question of nature vs. nurture is a legitimate question. One recent study conducted by the University of Virginia and several others including one in Australia studied 1,045 twins and their 2,051 children. Some of the parents were identical twins with others being fraternal. This affected the amount of genes that were shared among the siblings. Participants were twins from a volunteer twin registry and information was gathered through a series of phone interviews beginning in 1993 and ending in 2003. The study discovered that spousal fighting wasnÂ’t to blame for behavioral problems in their children. Rather, it was the genes that influenced how often they argued with spouses. These genes when passed to their children caused more conduct problems. The conclusion of the study was that in family therapy, more focus on the child rather than the parents would be more effective (Society for Research in Child Development, 2007). This conclusion supports the theory that it is nature or our genetics that influence this particular behavior. On the other end of the spectrum another study involved observing children in different childcare settings. Researchers from the National Institute of Child Health and Human Development studied the children beginning in 1991 from the age of one month until they were school age. These 1,364 participants were selected at birth and were studied through phone and personal interviews at three month intervals. The childrenÂ’s cognitive and social functioning was measured at certain intervals and followed up to the  children on sixth grade. It was concluded that center based care yielded more aggression and disobedience than other types of childcare, with the quality of childcare was also found to be a factor (Society for Research in Child Development, 2007). This conclusion supports the theory that it is nurture or our environment that influences this particular behavior and the type of care children receive is an important factor in a childÂ’s development. Both of these studies posed the question of whether the cause of a particular problem, this one being behavioral issues, is genetic or ones environment. Both of these studies looked exclusively at one cause or the other with little being discussed about the other possibilities. The differences in the studies was the length of time given to each study with the genetic study being short term and the childcare study involving observations over a period of time. Another difference is the twin study looked at parents of a specific group, that being twins. The child care study looked at the children of many different types of parents. While both of these studies have their merits, neither study was able to conclusively determine the cause of behavioral problems observed as being attributed solely to genetics or the environment. The question of which one plays a greater role will likely continue to be asked. Hopefully this leads to more research and answers that will further our understanding of human behavior.

Slave Women in Harriet Jacobs Incidents in the Life of a Slave Girl an

Slave Women in Harriet Jacobs' Incidents in the Life of a Slave Girl and Toni Morrison's Beloved Slavery was a horrible institution that dehumanized a race of people. Female slave bondage was different from that of men. It wasn't less severe, but it was different. The sexual abuse, child bearing, and child care responsibilities affected the females's pattern of resistance and how they conducted their lives. Harriet Jacobs' Incidents in the Life of a Slave Girl, demonstrates the different role that women slaves had and the struggles that were caused from having to cope with sexual abuse. Growing up as a slave Jacobs was constantly exposed to sexual abuse from her master. She was forced to learn what it meant to be a slave that was a women and the exploits that she would have to endure. A...there is no shadow of law to protect her from insult, from violence, or even from death; all these are inflicted by fiends who bear the shape of men."(Jacobs,361) The insults and violence that Jacobs endured from her master shaped the choices she made in life. He whispered foul words to her, causing Jacobs much pain. She was forced to lose her innocence early in life. Her master owned her so he was able to treat her and violate her innocence as he pleased. By losing her innocence Jacobs felt that she had done something wrong. She soon realized how she was different by being a slave that was a women. "She will become prematurely knowing in evil things. Soon she will learn to tremble when she hears her master's footfall. She will be compelled to realize that she is no longer a child."(Jacobs,361) The choices that Jacobs took in life were influenced by the position that she was in. She gave birth to two children, hoping they would hel... ...hat clearly inhibits motherhood. She would rather see her child dead in peace before she saw her child as a slave. However this did not happen this way because Beloved came back to haunt the family which resulted in her two boys leaving because they could not stand the pressure of living in a haunted house. So, again motherhood was inhibited because with out any children there is no mother hood and this is all because of slavery. Although Sethe prevented her children from being put back into the evil forces of slavery, there is a greater question of importance. Can Sethe be thought of as a heroine for releasing them from slavery or is it murder? These questions must also be related back to the real-life character Margaret Garner. Works Cited Morrison, Toni.

Learning Plan Essay

The learning plan described in this paper is to have students debate a topic related to the Civil War. The debate topic is â€Å"Was the Emancipation Proclamation enacted for moral reasons or political reasons?† The main concept of this learning plan is to have students work collaboratively to research facts, and recall and use facts from the Civil War unit to incorporate into their arguments. (It should be noted that the learning plan described in this paper will take several classes to complete, however the learning plan procedures will only address the class where the debate will occur.) It is assumed that debate skills were taught in a previous class. The learning theory certainly incorporates constructivist aspects. They are constructing knowledge rather than absorbing it. This is constructivist approach is illustrated through the collaborative nature of the assignment, as well as through the research that students’ must produce. In terms of the use of technology a nd media; the students will be instructed to research one source of information, from the internet, related to their argument. They must submit a one-page analysis of the information in which they found along with a references page. This must be submitted to the teacher a week before the scheduled debate. The teacher will assess the content of the paper, but the references page will also be important. Teacher must evaluate the kinds of internet sources that the students have used. The credibility of the internet source, and the strength of student’s research will be analyzed by the teacher. The purpose is to assess student’s traditional literacy and critical analytical skills (assessed when evaluating the content), and information literacy/interpretation skills of online material (assessed by reviewing the reference page). Finally, the teacher will hand back papers to the students, and he/she will instruct each group to use at least two of their group members’ papers into their group’s arguments. Media and technology will also be incorporated with the use of social media. The teacher will tell students that their debates will be recorded and submitted to youtube or a private school website (if issues of privacy are raised). Others will be allowed to view the video to evaluate the strength of each team’s arguments. Based on the comments of public viewers, a winner will be chosen (by popular vote). This popular vote will be incorporated as a small percentage into the assessment. This is being done as to allow students to  participate in new media opportunities within an educational context. Learning Plan Context Setting The high needs school will be a High School in the Bay Area, either in San Francisco or Oakland. There will be 25-30 students in an individual classroom.  The lesson will take place the week after the Civil War unit is finished. It is anticipated that the unit will last about two weeks, therefore the debate class will occur during the third week. The actual debate class will take up one class period. The content area is US History/Politics. The grade level is Juniors (11th grade). In sum, the curriculum unit is 11th grade, US History/Politics, Civil War unit. Standards According to California standards for literacy in History/Social Studies in 6-12th grades. A student must be able to demonstrate analysis of primary and secondary sources, and connect these insights to the understanding of the whole text. This ability will be addressed and assessed when students must incorporate information learned from the textbook with information gained from the internet, and use both sources of information, into their debate. The student’s ability to undertake this task will be evaluated by the teacher with the submission of student’s sources, and also during the debate. (http://www.cde.ca.gov/be/st/ss/documents/finalelaccssstandards.pdf.) Also according to California standards, students must be able to evaluate various explanations for events and actions. Learning Objective Students will be able to collaboratively demonstrate their knowledge of Civil War policy, events and information, from the textbook and from online sources, by formulating arguments to be presented within a debate. Learning Theory Applications Constructivism is certainly at play in this lesson plan: The activity allows knowledge to be organized into schemas, concepts, and worldviews. This activity is emphasizing the use of authentic activities by constructing knowledge through interaction with the environments (internet and peers), and applying it to real-life situations (debate). The collaborative component certainly illustrates constuctivism; learners will help each other create conceptual connections. Finally, students are working autonomously with the help of the teacher as facilitator, supporter, and model (Ormrod, 2006). Learning Accommodations: Individualized Education Plan for Special Accomodations: In each team, all students will be assigned a role. For example, â€Å"speaker†, â€Å"writer†, â€Å"time-keeper†. A student’s IEP will be taken into consideration when assigning roles. A student with an IEP, will be assigned a role that best fits their IEP. For example, a student with ADD, may be best suited to be a time-keeper since their attention span is not as focused. They may be anxious to change the pace of the group’s discussions, and therefore they may be eager to keep track of the time. Language Development needs: When assigning the internet-based research; the teacher will give ELL students a website to navigate to, instead of having the students navigate the internet themselves. Teacher will give explicit instructions as to where to look on the website so students do not feel too overwhelmed with the English language. Teacher will ask the students to try to comprehend some of the information, however if this proves too difficult, then the teacher will ask the students to find 15-20 words from the website that the student did not understand. The student will then find the meanings of these words in their own language. They must write at least a paragraph about the Civil War unit incorporating five of the words that they found on the internet. Also,  at least two of these words must be incorporated into the arguments of their team. Gifted and Talented needs: This is a challenging component to consider because a gifted/talented student does not necessarily mean an academic-rigorous student. To really tailor the lesson to address the interests of a gifted/talented student, then the teacher will have to be familiar with the personality of that particular student. However, some situations will be addressed here. First of all, from the research, the lesson itself befits that of a gifted/talented studen t. Competition, which characterizes a debate, usually suits the nature of gifted/talented students. The first situation to consider is a student who is gifted/talented, but not academically rigorous. This student will be given a leadership role within his/her team. He/she may be assigned to organize/manage all the ideas of the students. He/she is the one who will be given the rubric for what the teacher is assessing when observing the team’s discussions and arguments. He/she is the manager, and he/she will be assessed on their ability to keep his/her team on task. In this way, this student isn’t necessarily doing more â€Å"academic† work, but he/she is being challenged in a rather difficult manner. A second situation to consider is to have a gifted/talented student who is academically rigorous. The teacher will give this student a second component to add to his/her research paper. The student must connect textbook material and internet material to the US politics o f today. This is increasing the cognitive process from analyze (which all students must do with their research papers) to evaluate (Anderson and Krathwol, 2001). The student can choose to incorporate this extra component into their team’s arguments. Resource Accommodations: Low tech: There are no computers, projector, or internet access in the classroom. If this is the case, teacher may have to allocate time in different lessons to use school facilities where computers are available. Computers must be used so that the teacher can show students the kinds of websites that are credible, as well as to use sites, like youtube, to show students examples of debates. Computer use is necessary so teacher may have to take time before or after school to meet with students (who are willing) to show them the above-mentioned websites. Mid tech: One computer connected  to a projector is available in the classroom. The teacher can use this computer to show examples of credible websites, as well as to show examples of debates online. High tech: Class is equipped with several computers. Teams can go online themselves to view videos of debates and start research for their paper. In this way, the collaborative nature of the lesson will start even earlier (in the pre-plan ning stage). Content-Based Literacy Skills In terms of text-based literacy; students must incorporate information from their textbook into their arguments Critical thinking, reflective thought, and text-supported thinking will be illustrated when students must draw connections between internet-based information and textbook information while doing their analysis/research paper. This connection will be evaluated when student’s cute their sources within their paper. (This explanation will also illustrate students’ information literacy.) New Media Literacy Skills Performance: This skill is illustrated when students view sample debates on the internet and use this as models of performance in their own debates. Collective Intelligence: This skill is done when students are within their respective teams and they must draw upon their own and others ideas, research, and knowledge to formulate strong arguments. Judgement: This skill is illustrated when students must judge which websites and information are to be included in their research/analysis paper. Networking: Once again, this skill is illustrated when students must search, connect, and analyze information on the internet for the purpose of their research/analysis paper (Jenkins, 2001). Learning Material: Textbook: Learners will need textbook so that they can recall information. Paper, pen: Leaners will need so that they can write down information. Rubric: Both the learner and teacher needs. Learners need it so that they are aware of what’s expected of them while working in teams and formulating their arguments. Teacher needs it so that he/she can refer to it when assessing the team’s progress. Notes: Learners will need them as a reference when formulating arguments. Stopwatch/watch: This will be given to  the student whose job is timekeeper. Video Camera: Used to record the debate Learning Plan Procedures Phase I: Motivation Activity Teacher will show a short clip of a very powerful, interesting debate. Possibly a presidential debate. The clip will only show the most poignant part (according to the teacher) of the debate. Hopefully the clip will be no longer than 5 minutes long. (if there’s no computer available, then teacher must bring in her/his own computer.) In a class of 30 chair/table. There will be 15 chairs/ tables on each side of the room. They will be facing eachother. Learners will enter the classroom and sit down immediately with their team. The teacher will then show the video as soon as the class is seated and quiet. This activity is being done to motivate, encourage, and remind students of what a good debate looks like so that the output of the students’ debates can match skills such as speaking (clear and concise) and eye-contact of the debaters within the video. Phase II: Input (Teacher Driven) Activity: During this class, the teacher will, serve only as facilitator, therefore not much activity will be driven by the teacher. However, after the video, the teacher will remind students of the rubric that was given to them, and tell students that she/he is only their to assist in the logistics of the debate (time, flow, managing emotions if this becomes a problem). The teacher will also instruct students to take notes on each other’s arguments because this assignment will be important for their homework assignment. She/he will also remind student that they will be recorded. Teacher will tell all students to take out their rubrics. She/He will go over some key point from the rubric as it relates to the debate. The teacher will tell students to make sure that they keep these key points in mind because these points will be assessed during the debate. The teacher will instruct students to have their rubrics out for the entire class so they can monitor their team’s progress by themselves. Teacher will formally go over key questions from the rubric that he/she hopes the teams have incorporated into the nature of the debate (clear speech, eye contact,  concise points, respectful behavior) as well as into the content of the debate. In term of the nature of the debate, questions might look like â€Å"Is my team being quiet/respectful as the other team presents their arguments?†, â€Å"Are my responses to the other’s teams arguments not insulting?† etc. In terms of the content of the debate, questions may look like, â€Å"Did my team incorporate facts from the textbook?†, â€Å"Did my team use at least two credible internet sources within the argument?†, â€Å"Did my team follow special instructions assigned by the teacher (e.g. incorporating ideas from IEP students, ELL student, gifted students)?.† This activity and these questions serve to remind students of the importance of the collaborative nature of the learning objective. They also serve to remind students that they must be able to demonstrate their understanding of the Civil War unit, as well as their understanding of outside sources within the context of an argument. Phase III: Output (Learner Driven) Activity Students will take part in a debate. The topic is â€Å"Was the Emancipation Proclamation enacted for moral reasons or political reasons?† This activity will illustrate the learning objective in several ways. First, the collaborative nature of the previous classes will finally be demonstrated. Second, the students must illustrate their knowledge of Civil War policies within their arguments. Third, both sides’ arguments must include information from outside sources. The teacher will select one team to present their arguments first. Recording will begin The speaker of that team will stand up and come to the front of the class. They will present their team’s argument. In the argument they must mention the sources in which they got their information. For example, if they got a particular piece of data from the textbook, then they must state â€Å"As is presented in the textbook†¦Ã¢â‚¬ . If they got a particular piece of data from the internet then they must state, â€Å"As is presented on so-called website, or by so-called author†¦Ã¢â‚¬  They must also explicitly state how they used the â€Å"special instructions† from the teacher. For example, â€Å"(ELL’s student’s name) found that ‘compromise’ was not a possible solution of the Civil War.† In this example, it is assumed that compromise was on a list of words that an ELL student did not understand. He/she presented these list of words to  his/her team. The team reviewed the list, and chose to use the word compromise as part of their argument. The student will finish the presentation of his/her argument. The teacher will tell the next team to present its argument. The team will follow the same procedure as above. The teacher will then stop recording of the debate. This debate will naturally lead to questions, comments from both the teacher and the students. Phase IV: Culmination  The teacher will ask the groups to clear up any misunderstandings or misinformation the teams may have had within their argument. This is to give other team members a chance to speak about the argument, which reinforces the collaborative effort of the lesson. The teacher will also ask students how their team’s or the other team’s information and debate skills differed and how these things were similar to the debate presented in the beginning of the class. As a smaller activity, the teacher will instruct all the students to come up with one question, comment, critique of the other team’s argument. This assignment will illustrate each student’s understanding of the Civil War Unit because it challenges students to relate, connect, or counter-argue their own knowledge of the unit. This question will be submitted to the teacher. Phase V: Exten sion For homework, students will write a one-page analysis of the opposing teams arguments. The student will address the opposing side’s arguments. He/she will evaluate the argument’s weaknesses, strengths; and why he/she disagreed or agreed with the points that were made. Learning Plan Analysis Formative assessments will include analyzing the collaborative efforts of the team, the behavior of each team during the presentation of the opposing team’s arguments, how well each team member took on their role within their team, and how well the team incorporated textbook information, outside information, and ‘†special instructions† from the teacher into their argument. A summative assessment will include the teacher’s evaluation of the internet analysis/research paper, the one-page analysis of opposing team’s argument, teacher’s evaluations of the strength of the arguments, and finally the â€Å"popular vote† (the results of youtube or school-based website). Weaknesses of this lesson plan include time constraints, and the many assessments involved. It may be difficult to accurately assess how well each team members took on their roles. Some students may still be taking on more work than others. Also, incorporating ELL/IEP students proved to be a difficult task.. Strength of the lesson is it fosters team work, analytical skills, and gives students more power in the direction and implementation of a lesson. The teacher will implement these varied assessments in its first year, and then will evaluate the effectiveness of these assessments for future classes. The learning theories applied in the first phase was Vygotzky’s Cognitive Process. Students are witnessing two adults debating and they are expected to try to learn/imitate the behaviors of those adults. In the second phase, social cognitive theory is at play. The teacher both models desired behaviors/outcomes, as well as emphasizes self-efficacy and self-regulation. In the third phase, constructivism is illustrated. The debate is student-driven because the students are demonstrating their constructed knowledge within the debate. The assessments have a behaviorist component. Negative reinforcement (decrease a behavior) is illustrated when the teacher warns students that if they are not respectful or a team member does not contribute meaningfully, then they may be marked down (Ormrod, 2008).

The Importance of the Central Limit Theorem

The Importance of the Central Limit Theorem The central limit theorem is a result from probability theory. This theorem shows up in a number of places in the field of statistics. Although the central limit theorem can seem abstract and devoid of any application, this theorem is actually quite important to the practice of statistics. So what exactly is the importance of the central limit theorem? It all has to do with the distribution of our population. This theorem allows you to simplify problems in statistics by allowing you to work with a distribution that is approximately normal. Statement of the Theorem The statement of the central limit theorem can seem quite technical but can be understood if we think through the following steps. We begin with a simple random sample with n individuals from a population of interest. From this sample, we can easily form a sample mean that corresponds to the mean of what measurement we are curious about in our population. A sampling distribution for the sample mean is produced by repeatedly selecting simple random samples from the same population and of the same size, and then computing the sample mean for each of these samples. These samples are to be thought of as being independent of one another. The central limit theorem concerns the sampling distribution of the sample means. We may ask about the overall shape of the sampling distribution. The central limit theorem says that this sampling distribution is approximately normal- commonly known as a bell curve. This approximation improves as we increase the size of the simple random samples that are used to produce the sampling distribution. There is a very surprising feature concerning the central limit theorem. The astonishing fact is that this theorem says that a normal distribution arises regardless of the initial distribution. Even if our population has a skewed distribution, which occurs when we examine things such as incomes or people’s weights, a sampling distribution for a sample with a sufficiently large sample size will be normal. Central Limit Theorem in Practice The unexpected appearance of a normal distribution from a population distribution that is skewed (even quite heavily skewed) has some very important applications in statistical practice. Many practices in statistics, such as those involving hypothesis testing or confidence intervals, make some assumptions concerning the population that the data was obtained from. One assumption that is initially made in a statistics course is that the populations that we work with are normally distributed. The assumption that data is from a normal distribution simplifies matters  but seems a little unrealistic. Just a little work with some real-world data shows that outliers, ​skewness, multiple peaks and asymmetry show up quite routinely. We can get around the problem of data from a population that is not normal. The use of an appropriate sample size and the central limit theorem help us to get around the problem of data from populations that are not normal. Thus, even though we might not know the shape of the distribution where our data comes from, the central limit theorem says that we can treat the sampling distribution as if it were normal. Of course, in order for the conclusions of the theorem to hold, we do need a sample size that is large enough. Exploratory data analysis can help us to determine how large of a sample is necessary for a given situation.

Actinium Facts - Element 89 or Ac

Actinium Facts - Element 89 or Ac Actinium is the radioactive element that has atomic number 89 and element symbol Ac. It was the first non-primordial radioactive element to be isolated, although other radioactive elements had been observed before actinium. This element possesses several unusual and interesting characteristics. Here are the properties, uses, and sources of Ac. Actinium Facts Actinium is a soft, silver-colored metal that glows pale blue in the dark because the radioactivity ionizes air. Actinium reacts with moisture and oxygen to form a white coating of actinium oxide that protects the underlying metal from further oxidation. The shear modulus of element 89 is estimated to be similar to that of lead.Andre Debierne claimed discovery of an element he named actinium, working from a sample of pitchblende supplied by Marie and Pierre Curie. Debierne was unable to isolate the new element (which modern analysis reveals might not have been element 89, but rather protactinium). Friedrich Oskar Giesel independently discovered actinium in 1902, calling it emamium. Giesel went on to become the first person to isolate a pure sample of the element. Debiernes name was retained because his discovery had seniority. The name comes from the Ancient Greek word aktinos, which means ray or beam.The actinide series of elements, a group of metals between actinium and lawrencium possessing similar properties, takes its name from actinium. Actinium is considered the first transition metal in period 7 (although sometimes lawrencium is assigned that position). Although the element gives its name to the actinide group, most of the chemical properties of actinium are similar to those of lanthanum and other lanthanides.The most common oxidation state of actinium is 3. Actinium compounds have similar properties to lanthanum compounds.Natural actinium is a mix of two isotopes: Ac-227 and Ac-228. Ac-227 is the most abundant isotope. It is primarily a beta emitter, but 1.3% of decays yield alpha particles. Thirty-six isotopes have been characterized. The most stable is Ac-227, which has a half-life of 21.772 years. Actinium also has two meta states.Actinium occurs naturally in trace amounts in uranium and thorium ores. Because its difficult to isolate the element from ore, the most common way to produce actinium is by neutron irradiation of Ra-226. Milligram samples may be prepared in this manner within nuclear reactors.To date, there has been minimum industrial use of actinium because it is rare and expensive. The isotope actinium-227 might have use in radioisotope thermoelectric generators. Ac-227 pressed with beryllium is a good neutron source and may be used as a neutron probe for well logging, radiochemistry, radiography, and tomography. Actinium-225 is used for radiation cancer treatment.  Ac-227 may also be used to model water mixing in the ocean. There is no known biological function for actinium. It is both radioactive and toxic. It is considered slightly less toxic than the radioactive element plutonium and americium. When rats were injected with actinium trichloride, about half of the actinium was deposited in the liver and one-third into the bones. Because of the health risk it presents, actinium and its compounds should only be handled with a glove box.

Is there any relation between change of auditors and the client's Dissertation

Is there any relation between change of auditors and the client's stock price - Dissertation Example As the performances and financial transactions of a company have direct effect on the stock prices, hence choice of auditors is considered as an essential factor for every business. Depending on the individual needs and the performances of both the business and the audit team, change in auditors is also performed by several businesses, which in turn has either a positive or negative effect on the stock prices. This particular research has been focused on understanding the relation that change in auditors has with stock prices of a company. And, it could be obtained from this particular study that agency theory can be well associated with the employment of auditor agencies and that the change in auditors has a direct relation with the prices of stocks. 1. ... ry researchers on role of auditors, the relation between change in auditors and stock prices of client companies, and the positive and negative impacts of share prices on change in auditors. Both qualitative and quantitative data have been collected and analyzed to determine the reasons for change in auditors. Stock prices of client companies and characteristics of the firms significantly determine the relationship of the companies with their auditor firms. Different business organizations having different characteristics and processes in their businesses result in varying demands for the quality of audits. This is particularly in association with external auditors that perform an audit over the companies. Some of the common determinants of business firms for choosing the quality of auditors include their membership in the finance sector, leverage, size, profitability and their market-to-book ratio. Thus the choice of auditors by an organization is related to the above mentioned fact ors (Aksu, Onder and Saatcioglu 2007). The role of auditors takes place in a business environment that is highly regulated. Both the audit firms and the individual auditors have certain independent requirements along with ethical fulfillment that they need to encounter and follow (Great Britain 2011). Quality auditing is what is expected by every business organization and hence the choice and selection of quality audits is considered as essential for business firms. Specific skills are essential for quality audit works to be performed by auditors. This includes personal talents of the auditors, dedicated training, and wide range of experiences. It is often considered as similar to police work and based on the audit, a company’s performance in terms of financial dealings and achievements

Globelaztion context - Essay Example hat people have slept on the geo-economics lies, and then everyone must be ready to find out if the world is flat as the lies state without wasting time. The author also states how if found out by accident how the earth if flat. He found out the truth according to lies late February last year. Friedman (2005) has used the interview while creating a discovery channel program to justify what Indians believe about the earth being round or flat. The video is for a lecturer who is talking about the global health of two hundred countries two hundred years ago and beyond. He states that having data is not enough but it very critical to make them presentable enough that people can understand. To do so, he talks about the animation of data in real space. Using the real space animation uses different color in presenting countries. The size of the color also shows the size of the population. The speaker also talks about the life expectancy of persons in different countries. The speaker also talks about the factors that have led to the development of some countries. Again, the speaker identifies the impact of the world war to the development of many nations. The speaker has categorized the global competition of the nations in years from 1810 up to the now identifying the development strategies and the factors that affected the countries. The author also defines the closing of the economic gaps between countries and identifying factors that have contributed to the closing of the
