Principle Of Superposition Essays - Plate Tectonics, Subduction

Principle Of Superposition Lesson 1 Assignment Unit I 1. In addition to various bits of information, there are 3 primary principles geologists use to place layers of rock according to age. The first, Principle of Superposition is the un-changed consecution of the rock, which contains the oldest stratum (a single sedimentary rock) located in the bottom of the rock. Superposition is the primary method to unveil the order of succession in which layers were formed in the rock. The second, Principle of Original Horizontally states that most strata is originally formed horizontally, which explains that steeply dipping strata was deformed at a much later date. This brings us to the third and last, Principle of Original Lateral Continuity. This is a stratum that patterned in all directions until the rock layers stopped at the ends of its original placement. 2. Catastrophism is a scientific method to explain extreme changes in geological structures in a short period of time. These catastrophism events may include earthquakes, severe flooding, volcanoes and extreme wind conditions. Uniformitarianism is the belief in slow evolution and slow change in geological Earth events. This states that Earth can only change over a long period of time. Different parties, one believing in catastrophism and the other believing in uniformitarianism collided in the 19th century though being in close agreement at the same time. Under closer studies of the Paleozoic and Mesozoic era, these two theories posed problems for them, too short for uniformitarianism and too long for catastrophism. 3. By using the radioisoyope dating method, scientists are able to measure the age of a substance. This method is possible for measuring the invisible radiation emitted by phosphorescent substances. These atoms are called parents, and as it decays it will become a daughter. By knowing the time it takes for an isotope to change from a parent to a daughter, we can measure the time without the interference of effects caused by catastrophism and uniformitarianism. To quickly explain the measuring process, you must take the # of parents and daughters mean in the rock and the percentage of parents remaining should be added to the measuring curve scale to find the amount of half-lives remaining. This will give you the age of the rock. 4. The planet Earth is estimated 4.6 billion years old. Scientists were able to reach that number by using radioisotope dating. Using this method, scientists have measured from the Precambrian, Mesozoic all the way to the present. The process and details of radioisotope dating are explained above in 3. 5. a. Precambrian era, being the longest era consumed 4 billion of the 4.6 billion years of the Earth's history. Rocks during that age contained very little fossil history and were altered so much that it makes it difficult to know the conditions of that era. b. Paleozoic era began 570 m.y. ago and contained some of the earliest found life forms including the Trilobites, sharks, corals and the first life on continents including forests, insects and reptiles. The formation of the northern and southern Appalachians was also accomplished. c. Mesozoic era extended from 245 m.y. to 65 m.y.. This era was the death of the long survived trilobites but the beginning for dinosaurs and birds and the Andes. d. Cenozoic era extended from 65 m.y. to the present day. This was the era of animals including horses, apes, humans and the formation of the Rocky Mountains, Alps and Himalayas. Unit II 6. The Earth's rocks are divided into 3 different types. The first are igneous rocks, which are formed by volcanic magma coming to the surface and cooling. The second, sedimentary rocks are formed from the disposition or accumulation of sediments (mud, clay, sand, gravel and skeletal remains of plants and animals) from water, wind or ice. There also is a second class of sedimentary rock that is formed a completely different way. Instead of mechanically depositing, it is chemically deposited forming limestones and evaporates. The third and last class, is the metamorphic rock. Metamorphic rocks are any rock that has been altered by being crushed, squeezed or heated. These rocks can be identified by their unique mineralogy and structure. As a result of the changes, new types of rocks are formed. 7. Beginning with the granite, the most well known class of rock. These rocks have a speckled appearance

Jerry Mathis Essays - Thomas Jefferson, American Slaves, Free Essays

Jerry Mathis Essays - Thomas Jefferson, American Slaves, Free Essays Jerry Mathis March 2018 American Presidents Prof. Steven Brady The Declaration of Hypocrisy During the 18th Century, the United States of America was in the process of gaining independence from Europe and establishing themselves as a strong country. Many new Americans saw a great opportunity to step up and contribute ideas that could turn America into a true international superpower. They decided to create a democracy, the government where the leader ideally represents the voices of many public citizens. One of these leaders was the third president and member of the original founding fathers, Thomas Jefferson. While most Americans view Thomas Jefferson as an upstanding, honorable, and accomplished man, he was plagued with the moral contradiction of having fathered children with one of his slaves, Sally Hemings, spurring a great deal of controversy. Jefferson preached equality, but owned slaves. He fought for individual rights, yet had intimate relationships with people who were his property. Jefferson's virtuous demeanor has been questioned when celebrating his legacy an d historians often argue how hypocritical he really was. However, by delving into Jefferson's relationships with his slaves and by looking at his plantation, Monticello, it is easy to tell that Jefferson did not see slaves as less of a person than others.Thomas Jefferson's parents are Peter Jefferson, a lawmaker in the Virginia House of Burgesses, and Jane Randolph. Growing up, Jefferson was taught discipline and self-perseverance. His father taught him how to read, write, and how to do a numerous amount of outdoor activities. However, he soon had to put his child behavior behind him and without warning take over being the man of the household. Peter Jefferson died in 1757, when Thomas was only 14 years old. Thomas Jefferson now had to take responsibility over his younger siblings. He inherited many of his father's belongings, and used these to his advantage. Unable to completely enjoy his youth, attended private schools and was provided with the best tutors where he studied several languages. Due to Jefferson's early onset maturity, education became his top priority. In 1760, Jefferson enrolled in the college of William and Mary, located in Williamsburg, Virginia.Thomas Jefferson used this education to gain influence within the Democratic-Republicans. He stood out as the party's leader, and used the publicity and high profile to rise in government rankings. Jefferson wrote the Declaration of Independence in 1776, which is what most historians study to grasp Jefferson's ideals. Jefferson writes about the fundamental goals of life, which he pulled from writer John Locke to be "life, liberty, and the pursuit of happiness." Jefferson made it clear that he believed the only point of government was to protect these ambitions, allowing all humans to pursue their happiness. Jefferson also speaks about the equality of men, saying, "We hold these truths to be self-evident, that all men are created equal, that they are endowed by their creator." Jefferson knew that his ownership of slaves contradicted the very principles that he was trying to bestow upon the young nation. He refused to grant freedom to his own slaves because of their significances to his wealth, but overall, he repeatedly and overtly condemned slavery. Jefferson inherited land from his deceased father, and waited until 1770 to begin building his plantation in Charlottesville, called Monticello. Jefferson's personality was reflected in his home, that Francis Cogliano in his book "Thomas Jefferson: Reputation Legacy" described as "a working plantation, a family home, an informal innand not least a reflection of Jefferson's view of the world and how he wanted to be viewed by the world." (Cogliano, 108) This estate was more than 10,000 acres and housed over 180 slaves who cared for his estate while he was away. The way his home was decorated, with many mementos from Native Americans, showed his interest in other cultures. In 1772, Jefferson married Martha Skelton Jefferson and moved her into his home at Monticello. Martha came from a well-established family; John Wayles, her father, was a well-known lawyer. Wayles' daughter, and Martha's half-sister Sally Hemings became one of Jefferson's slaves. (Cogliano, 170) After Martha died in 1 782, Jefferson became intimately involved with Hemings. James Callender took the liberty to write about this controversy in the Richmond Recorder. Callender

The accreditation process for criminal forensic laboratories Research Proposal

The accreditation process for criminal forensic laboratories - Research Proposal Example Probably one of the most significances advances in forensic technology evolved from one of the most significant tragedies of our history: the attack on the World Trade Center in New York City, 9/11. "After the terrorist strikes, 21,741 remains were recovered. So far, 11,989, or 55 percent, have been identified. More than 1,100 of New York's 2,750 victims have not been identified because many of the remains were too badly compromised by heat and time . . ." (Frasier). Today, years after the attack, identification of victims through DNA technology is still going on. Much of this work is being done at a private lab in Ann Arbor, Michigan called Gene Codes Corp. Gene Codes Corp's founder and CEO, Howard Cash calls his work, "the most important thing I'll ever do in my professional life" (Detroit Free Press). Cash's company has also worked to identify victims of the tsunami in Asia, and the London subway bombings. "Cash and his colleagues created software they called MFISys (pronounced EM PHASIS), for mass fatality identification, for the 9/11 project. It compared data from three types of DNA tests on 20,000 partial human remains to the DNA from more than 3,000 cheek swabs of victims' kin and 8,000 personal effects. They updated the software nearly 140 times . . ." (detroit free press). In June of 2008 another victim of the attack has been identified through remains recovered in the past two years in and around Ground Zero, according to the AP. "Examiners made the identification in the past two days after retesting remains from the original recovery effort following the attacks on the World Trade Center" (Frasier). The use of forensic DNA technology is considered critical to the execution of justice in today's world. Both the science of DNA and the lens through which forensic science has been scrutinized have evolved since it was first used to identify a suspect in the rape and murder of two young women in Leicester, England in the mid 1980's (Presley, 1999). Soon after its landmark use in Europe, DNA technologies have become more sophisticated and more widely used in forensic settings in the United States, yet it was decades after its first admission in court that the laboratories responsible for the analysis of the evidence were accredited by a professional organization. For these reasons, the use of DNA technology has been at the heart of the push for accreditation for all criminal forensic laboratories and while these practices became standard in the courtroom relatively early in their history, they were not without controversy. In fact, it was the controversy which initially led to the accreditation process. In an article in the Journal of Law, Medicine and Ethics, Paul Giannelli wrote about the 1989 Supreme Court case "People V. Castro". This case was one of the first to criticize DNA evidence as it was presented in court. What was successfully argued in this particular case was the " . . . DNA evidence testing laboratory failed in its responsibility to perform the accepted scientific techniques . . ." (Giannelli, 2006). It is important to note that the science of DNA technology was not called into question; it was the methods used by the laboratory that resulted in the conviction being overturned. Over half a century before the Castro case, another legal decision,

Symposium and Phaedo determine why Socrates is spared the tragic fate Essay

Symposium and Phaedo determine why Socrates is spared the tragic fate of many old Greek heroes - Essay Example In his analysis, Socrates seeks the interpretation of love from Diotima, a priest of Zeus. Socrates gives the genesis of love, which emanates from Resource and Poverty. To him, Resource is the father of Love and Poverty is the mother of Love. Socrates further argues that Love has many dimensions, it can be patient, harsh, beggarly or deceptive and, therefore, it balances itself into these virtues depending on the situation at hand (Conford, 56). Socrates further argues that people have the desire to procreate, physically and mentally, and for them to bring forth children of high intellect; they have to become philosophers as this will ensure the immortality of their children. This analysis of Socrates in the Symposium makes him a Great Greek hero. Phaedo depicts the death of Socrates; just as Symposium, it is a work by Plato. It analyzes the beliefs of Socrates just before being executed by the Athenian courts for not believing in the Athenian gods (Conford, 32). This analysis by Plato emanates from Phaedo, a student of Socrates. The analysis of Phaedo represents Socrates as a great Greek hero because of his philosophical views of death. Socrates introduces the Greeks into the notion of life after death, arguing of the immortality of the soul. He gives four reasons as such: The third argument is on the fact that visible, mortal and real thins are not the same as invisible, immortal and unreal. The Soul is invisible, therefore, cannot pass the same process as the body which is physical. In conclusion, Socrates compared to Achilles, is greater. Achilles was a warrior but did not embrace wisdom and knowledge whereas Jason is depicted as loving power. Jason and Achilles were warriors who pursued their goals through violent means while Socrates pursed solutions to his problems by searching on wisdom. To Greeks, knowledge is more beneficial that courage or even power, because

Of these factors, changes seen in the issues that provide the benefits and complexities of the work level contributed the maximum for increased turnover while marital status seemed to be the least important for voluntary turnover for the employees. 3.5 The statistical model introduced in NASA and ATK for calculating the employee turnover might have benefitted the employees there buy it is not necessary the model would do the same for other companies too. The model brought information more about the employees who were found in the bottom lines jobs. There was no information about the other employees in the hierarchy. Besides, there were less analytical skill sets in the model which would be necessary while understanding the work climate in an

Should the United States Make English the Official language? Essay exam

According to the 2011 census, over 20.8 percent of the United States population spoke another language other than English (www.us-english.org). Language barriers, cultural differences, and immigration have been a part of life in the United States for decades. Language is considered a vital tool in the construction of someone’s identity and an expression of culture. In the last 200 years immigrants have chosen to make the United States their home, but some proceeded with caution by slowly adapting to the English language and culture. If a country doesn’t have an official language is usually due to distinct historical or cultural reasons. As I began reading articles on this topic, I was amazed that the great country I live in doesn’t have an official language. I begin to wonder why this is the case. Many countries have an official language in which all the official business, daily activities and other formal activities are conducted. There are even thirty (30) states that have succeeded through their own statutes to declare English as an official language of their particular state (www.us-english.org). It seems that this topic has been a heated debate for the past couple of decades, which has caused some division over the issue. I learned that there are a variety of pros and cons that you can argue about this issue. I chose to be a part of the pro English side for three reasons: I believe that making English our official language (1) would allow the education system to focus on English as the primary language, (2) it would unite our country in regards to racial discrimination, and (3) our government and business operations would be a little more streamlined. The United States is often called the melting pot because of th... ... immersed society through our businesses, education systems, and government sectors. I definitely support Congress in their attempts to continue fighting this battle to make English the national language. Works Cited Baron, Dennis. â€Å"Don’t Make English Official.† Pbs.org. 1996.

Ab105 Organizational Behavior Critical Thinking

AB105 Organizational Behavior Critical Thinking The Management of Organizational Justice By Russell Cropanzano, David E. Bowen, and Stephen W. Gilliland Summary of the key issues This paper has addressed the organizational justice from various aspects and provided recommendations to enhance the fairness in the managerial activities. Firstly, it has discussed the importance of justice in workgroup from its long-range benefits, social and ethical considerations. Secondly, the authors analyzed the three components of organizational justice, namely distributive, procedural and interactional justice in details to highlight the differences between the three in business activities. Next, the paper summarized the influences of organizational justice and these include enhanced trust and commitment, improved job performance, more helpful organizational citizenship behavior, as well as greater customer satisfaction and loyalty. Lastly, after identifying the critical significance of organizational justice in building a company’s identity, recommendations on how to enhance the fairness in managerial activities are proposed. The authors had cited examples from several past studies and discussed from five angles which are hiring, performance appraisal, reward systems, conflict management and downsizing. Other Theoretical Perspectives on Organizational Justice This paper has mentioned the equity theory which is one of the earliest theories of justice brought by Aristotle. This theory emphasizes that people should be paid in proportion to their contributions. Nevertheless, equity theory focuses more on the distributive justice. Through careful research, there are other perspectives and positions on this issue. Fairness heuristic theory Fairness heuristic theory is concerned with how people react to outcomes of their authorities, and makes some predictions concerning the relationship between perceived fairness of procedures, perceived fairness of outcomes and acceptance of outcomes. This theory highlighted that employees would make decisions about others’ trustworthiness. It also discussed whether one can avoid exploitation by using available information. Uncertainty management theory Uncertainty management theory assumed that people manage uncertainty by using fairness; for instance, receiving information on the reliability of an authority figure may reduce uncertainty about unjust treatment in the future and alleviate doubt about the outcome of a possible figure. Uncertainty theory has explained why people care about justice and how they form justice judgment. This theory has relevant implications as information on managerial decisions should be provided to gain the trust from the employees to enhance procedural justice. Group engagement theory This model explains why and how procedural justice shapes cooperation in groups, organizations and societies. It has established a link between justice and corporation via its several hypotheses, such as the importance of procedures in shaping one’s social identity within a group, and the impact of this social identity on his attitudes, values and behaviors. Group engagement theory has provided insights in organizational justice as managers should treat people fairly to win their corporation. Evidence Assessment In general, the evidence provided in this paper is reliable and well-established. The key issues of the article such as importance of organizational behavior and recommendations on fairness workplace enhancement are thoroughly – discussed. The authors had researched over a wide pool of studies across a time span of 20 years, ensuring the relevance, accuracy and sufficiency of the data. Nonetheless, there are some minor limitations. First of all, little evidence was demonstrated to support the discussion on prescriptive and subjective justice, with mere definition of the two, which in turn affects the completeness of the analysis on organizational justice management. Secondly, the authors mentioned about the external equity in affecting reward system, but no proof was offered to support the claim on the influence on the disparity of salaries from the external marketplace. Lastly, although this paper has detailed coverage on the improved employee organizational behavior by establishing organizational justice, it only focuses on the procedural justice and this coverage is insufficient in my viewpoint. Other research suggest that all the three types of organizational justice have direct relationships on enhancing citizenship behavior as â€Å"trust appears to be an important mediating variable (Konovsky and Pugh, 1994). Organizational justice enhances employee trust, which in turn stimulates the display of citizenship behavior. † Assumption Analysis Several assumptions are identified in the analysis of this paper. This paper assumes that self – interest motives favor equity and people across different age groups, genders, races and education levels will perceive justice similarly (which might not be necessarily valid). Another underlying assumption in the managerial activities is that decision makers will treat the employees with genuineness while undertaking the recommended measures, because the absence of the sincerity will make the employees feel disrespected and manipulated. The influence of different contexts plays a key role in organizational justice as it will affect one’s justice perceptions. Out of all the variables, gender and culture are the main factors. Studies have shown that male’s major concern in reward allocation was protecting their own interests while females’ interests lie on maintaining the welfare of all group members. Furthermore, in a society with emphasis on collectivism, members emphasized more on particularistic principle of need or social status distribution instead of equity, as compared to societies based on individualism. Conclusions, Implications and Consequences This article has provided a detailed understanding of organizational justice. In conclusion, injustice in an organization will create problems, leading to inefficiency and unproductivity while justice acts will provide excellent business opportunities and maintain respect and trust within organizations. Therefore, it is advisable to put in efforts in improving distributive, procedural and interactional justice simultaneously in managerial activities. Furthermore, managers could also apply different organizational justice measures according to employees’ various justice perceptions which vary with genders and cultures, in order to reap the maximum benefits from exercising organizational justice in a workplace.
