Dating Methods Essay -- essays papers

General Differances Between Relative and Absolute Dating Methods Getting dates for fossils that are found in sites being excavated by anthropologist is very important. Dates show the evolution from early hominid specimens to our own species, Homo homo sapiens. There are many methods that can be used to acquire these dates, but all of these methods fall into one of two catorgories. They can either give a absolute date or a relative date. An absolute date is one in which you get an actual date in years. Also known as chronometric methods. Relative dates do not give an actual date in terms of years, but they tell you if one fossil is older or younger than another fossil. Ushally relative dates are given in terms of the column of earth they are found in. This is called striatigraphy. In sites like Olduvai gorge their are geological layers of vocanic ash and sediment. When a anthropologist finds a fossil in a undistirbed layer of gray ash, you know that it is younger than the fossil in the layer of red ash below, and that fossil is younger than the fossil in the layer of brown ash below it.(Johanson 65) The basic theory here is that a certian site cantians a geolgical column key that is made up of differant strata layers, the fossils get older as they move down the key, and are found in differant layers of strata..(Scully 2) Relative dates have a couple of major problems. One is that the earth moves in many ways and this can distrube the layers of sediment putting younger fossils below older ones. Another is that you can not tell exactly how much younger or older something is from somethinng else and you can not date differant fossils from differant sites with thes relative dating methods. Absolute dating, unlike realative dating, gives the anthropologist an exact date in terms of calander years. These dating methods are much more reliable and can be used in many differant sites with many differant fossils. Absolute dating bases it’s dates on the natural radioactivity of differant elements found in the world.(Johnston 216) There are certian elements that occur in differant forms, these elements are called isotopes. Each one of these isotopes has a differant atomic mass than others. Some of thes isotopes are radioactive, meaning that they give of radiation in either alpha or beta form, as they de... ... has a half-life. C14 is the radioactive isotope of rearular carbon, c12. The cocentration of C14 in the body is one billionth of a gram in the body to one gram of C12. This C14 is contantly decaying, but through animals and plants breathing it is replenashed when an organism is alive. When the animal dies the C14 intake stops and a decay that is not replenashed.(Comas 456) During life an organism have a specific activity of 15.6 disintigrations per minuate per gram of regular carbon in thier body.(Comas 456) â€Å"After life and C14 intake cease and the equilibrium is halted, radioactive disintigration of C14 occurs, and after 5,700 years this activity will have decreased to 7.8 disintigratuions per minuate per gram of carbon in the body.’(Comas 457) This means that the ratio of C14 to C12 left in the fossil when it is found can give a date in years. Carbon-14 dating has a half-life of 5,700 years, with the lower limit of 1,000 years. The upper limit used to be about 30,000 years because after that the ratio was too small to analis. Recently reaserch by Haring and deVires has let scientist put the upper limit at 100,000 years old.(Comas 457)

Current beliefs about how the first peoples Settled North America Essay

1. Explain current beliefs about how the first peoples settled North America, and discuss the ways in which they became differentiated from one another over time. 2. Describe the founding of European nations’ first colonies in the New World. The information in our text shows many different opinions on how North America was settled. An example would be the discovery of the Kennewick man. The discovery of the skeletal remains opened the door to more opinions of North American Settlement. It is still believed that the initial North American settlers are the Paleo-Indians (www. betheluniversityonline.net, 2012). The Archaic era followed with the development of agriculture. This trend was perhaps the most significant development, because settled agriculture permitted the establishment of a sedentary existence, without the need to pursue herd animals (www. betheluniversityonline. net, 2012). A food source could now be provided from grown crops. The Archaic era was then followed by what is called the Pre-Columbian era. The Pre-Columbian era is when the development of societies began to happen. The societies developed because they were now able to provide the necessary food source by growing crops. The crops gave them the ability to remain in one area for a longer period of time. There are many reasons that caused the various tribes to become differentiated from each other. Language caused a lot of issues among the different tribes. Territorial disputes, competition for resources, and traditions caused most of the instability between the settlers (www. betheluniversityonline. net, 2012). The land was the major issue among the settlers because it affected trade. Reference: Schultz, K. , Hist2, Volume 1, History of the United States I, Bethel University Online https://www. betheluniversityonline. net/cps/SectionFramework. aspx? SectionID=254 When Europe voyage was intended to expand their trading options. Few sought to create lasting settlements, and even fewer sought to colonize these exotic lands (www. betheluniversityonline. net, 2012). Wealth was one of the biggest lures to the European’s. The competitive profits from this wealth led to them to colonization and would give them the power to defend what they had discovered. Portuguese would be followed by Spain and this would lead to the Pope’s intervention. He would draw a line from the North to the South dividing the land between the two. Spain would have claim to the West and Portugal would have claim to the East. Despite Portugal’s early ambition, Spain would be the first to establish colonies in North America (www. betheluniversityonline. net, 2012). This would lead the two to a war that ended in nearly annihilating the two because of death and disease. The Spanish colonization lead to the development armies called the conquistadors. The conquistadors would move in and devastate populations and take over the land. This would lead to the enslavement of the Indians. You would then have the French and English to follow this adventure to the New World. Four reasons for the English to become more interested were Religious reformation from Catholicism, Social because the impoverished Englishmen were seeking to escape poverty, Economically investing stopped in the textile market looking for opportunities in the New World, and Geographically Queen Elizabeth’s Monarchy stabilized the throne and allowed England to participate in New World ventures (www. betheluniversityonline. net, 2012).

Internet Small Computer System Interface Essay

A heterogeneous network of both IP-based SAN’s and FCP-based SAN’s should be setup based on a standard naming convention in order to facilitate communication between the client applications and the SAN which stores information. The network architecture should ideally be setup using a naming convention which is simple and precise, whilst facilitating communication between all of the network resources. This technique is based on having a convention which links a variety of technologies together as well as other resources seen on a network. A heterogeneous network consists of various network nodes with various protocols and operating systems in operation together. In the case of a Storage Area Network (SAN), the various operating systems in use on the network need to be able to see the remote storage volumes as if they are locally attached, therefore speed is essential to the successful working of a SAN. The use of a descriptive naming convention is also important as it means problem identification can be made easier and helps to minimize operator errors on the network. There are a number of protocols in operation on every network, and the need for an efficient protocol for SAN use is paramount. The current options for running a SAN are to use standard TCP/IP protocols namely the Internet Small Computer System Interface (iSCSI) protocol, or to use a specific protocol called FCP which usually operates over bespoke fiber infrastructure. These protocols are different in the way they operate, however can in fact be used together to improve the performance of a SAN. A naming convention suitable for a TCP/IP based network is very different to a naming convention for an FCP based network. TCP/IP is a network protocol which is used for communication between resources on a standard LAN, however FCP is a protocol which sends SCSI commands via a fiber optic cable to remote storage devices. The iSCSI protocol allows various network storage resources to be identified and used over standard network protocols, which requires compliance with the standard network naming policy, yet which enables the specific nature of their operation to be identified. Naming conventions for the LAN and SCSI storage devices should comply with standard network naming conventions. The servers and iSCSI devices which operate on a network should be been named in compliance with a standard policy and should be unique on the switch fabric of the network. Standard SAN naming conventions should be created with a few factors in mind, each component should be named based on its physical location, what it connects to, which database it is used by, and another unique field of identification. Naming conventions are important because they can save administrators time and effort, and must be created whilst considering many factors. Initially there must be a system whereby network names are created centrally and uniquely so that duplicate records are not made. This naming approach must be consistent throughout the network, and it must be applied across the entire organization regardless of location or operation. This element of the naming convention helps to prevent the duplicity or confusion of network names and is required to enable a high performance network to operate. This issue is not so important when dealing with an FCP-based SAN, because the devices are connected by a separate network of fiber which cannot usually be accessed by resources on the standard network which do not use specific applications or databases. In conclusion the operation of a storage area network relies on speed and an efficient and effective naming system which is able to be managed, diagnosed and repaired where necessary in the simplest and most cost effective way possible. This must be done consistently when using the standard TCP/IP protocol, however specific FCP SAN protocol allows for a much simpler convention.

Nomination Process for Supreme Court Justices

Nomination Process for Supreme Court Justices The nomination process for Supreme Court justices begins with the departure of a sitting member of the high court, whether by retirement or death. It is then up to the president of the United States to nominate a replacement to the court, and the U.S. Senate to vet and confirm his choice.  The nomination process for Supreme Court justices is among the most important obligations on presidents and members of the Senate, in part because members of the court are appointed for life. They dont get second chances to make the right choice.   The U.S. Constitution gives the president and the Senate this vital role. Article II, Section 2, clause 2 states that the President â€Å"shall nominate, and by and with the Advice and Consent of the Senate, shall appoint ... Judges of the supreme Court.† Not all Presidents have the opportunity to name someone to the court. There are nine Justices, including the chief justice, and one is replaced only when he or she retires or dies. Forty-two presidents have made nominations to the Supreme Court. The president with the most nominations was George Washington, who had 13, with 10 of those being confirmed. The President’s Selection As the president considers who to nominate, investigations of possible nominees begin. The investigations include a probe into a person’s private background by the Federal Bureau of Investigation, as well as an examination of the person’s public record and writings. The list of possible nominees is narrowed, with the goal being to ensure that a nominee has nothing in his or her background that would prove embarrassing and to guarantee that the president selects someone likely to be confirmed. The president and his staff also study which nominees agree with the president’s own political views and which ones would make the president’s supporters happy. Often a president confers with Senate leaders and members of the Senate Judiciary Committee before selecting a nominee. This way the president receives a heads-up on any potential problems a nominee may face during confirmation. The names of possible nominees may be leaked to the press to gauge the support and opposition to different possible nominees. At some point, the president announces the selection, often with great fanfare and the nominee present. The nomination then is sent to the Senate. The Senate Judiciary Committee Since the end of the Civil War almost every Supreme Court nomination received by the Senate has been referred to the Senate Judiciary Committee. The committee does its own investigation. A nominee is asked to fill out a questionnaire that includes questions about his or her background and to fill out financial disclosure documents. The nominee also will make courtesy calls to various senators, including party leaders and members of the Judiciary Committee. At the same time, the American Bar Association’s Standing Committee on the Federal Judiciary begins evaluating the nominee based on his or her professional qualifications. Ultimately, the committee votes on whether a nominee is â€Å"well-qualified,† â€Å"qualified,† or â€Å"not qualified.† The Judiciary Committee then holds hearings during which the nominee and supporters and opponents testify. Since 1946 almost all hearings have been public, with most lasting more than four days. The president’s administration often trains a nominee before these hearings to ensure that the nominee does not embarrass himself or herself. Judiciary Committee members may ask nominees about their political views and backgrounds. Since these hearings receive a great deal of publicity, senators may attempt to score their own political points during the hearings Following the hearings, the Judiciary Committee meets and votes on a recommendation to the Senate. The nominee may receive a favorable recommendation, a negative recommendation or the nomination may be reported to the entire Senate with no recommendation. The Senate The Senate majority party controls the Senate agenda, so it is up to the majority leader to determine when a nomination is brought to the floor. There is no time limit on debate, so if a senator wants to conduct a filibuster to hold up a nomination indefinitely, he or she may do so. At some point, the minority leader and majority leader may reach a time agreement on how long a debate will last. If not, the nominee’s supporters in the Senate may attempt to end debate on the nomination. That vote requires 60 Senators to agree to end debate. Often there is no filibuster of a Supreme Court nomination. In those cases, a debate is held on the nomination and then a vote is taken by the Senate. A majority of voting senators must approve the presidents choice for the nominee to be confirmed. Once confirmed, a nominee is sworn into the position of justice of the Supreme Court. A justice actually takes two oaths: the constitutional oath that is taken by members of Congress and other federal officials, and a judicial oath. Key Takeaways: How a U.S. Supreme Court Justice is Nominated Step 1: A sitting justice retires or dies, leaving a vacancy on the bench.Step 2: The president nominates a candidate to replace the departing justice.Step 3: The nominee is vetted by the Federal Bureau of Investigation.Step 4: The Senate Judiciary Committee conducts its own investigation and hearings with the nominee. It will then take a vote on whether to send the nomination to the full Senate for confirmation. If the committee does not approve of the nominee, the candidate is dropped from consideration.Step 5: If the Senate Judiciary Committee approves, the full Senate votes on the nomination. If a majority of the 100-member Senate approves, the nominee ascends to the U.S. Supreme Court.

What Are the Essential Skills to Be Possessed by a Manager Essay Example

What Are the Essential Skills to Be Possessed by a Manager Essay Example What Are the Essential Skills to Be Possessed by a Manager Essay What Are the Essential Skills to Be Possessed by a Manager Essay What are the essential skills to be possessed by a manager? A:- In order to perform your role as a good manager, you need to possess and exhibit a range of skills to plan, control, organize, lead and take decisions of an organization. In this article I am giving a brief idea of those unique set of skills needed for a professional manager. Planning skills It’s often needed to define the future of an organization. Managers must be able to ensure that his company does exist in the future. Hence his planning skills include ability to Forecast future environment Think ahead Plot organizational objectivesChoose strategies to attain these objectives Reach their performance standards When an organization increases its complexity, it needs its managers to acquire skills as needed to fit the present needs of the system. Organizing skills Organizing process follows the planning process. Its skills can be broadly spelled as the ability to Analyze and describe various tasks Select, train a nd appoint people Define roles, authority and controls Change these working links whenever necessary and make these changes flexible It depends upon the managerial skills to achieve the best you can, with the limited resources available.Leading skills A leader must be able to know the values, personality, attitudes and perceptions of his subordinates. Value is an opinion or belief a person holds about something while personality is a sum up of personal traits of an individual. It’s determined by our physical constitution, beliefs and values he holds. Perception is how a person interprets something from what he see, smell or feel while attitude is a person’s behaviour to a particular event, situation or person. Though we can’t observe it directly, we can observe its consequences.Attitudes can be learned and have three aspects – cognitive, affective and behaviourial. manageskills2 Controlling skills It consists of actions and decisions which managers undert ake to ensure that outputs obtained are consistent with desired ones. Any difference between the actual and planned results must be corrected by management by taking appropriate actions. So, a management has a pre-determined standard according to which outputs are needed to be checked. manageskills1 Decision making skills They are related to planning process and pervade all other modules of managerial skills.A manager’s skills and effectiveness lies in making appropriate and timely decisions most suited to that particular situation. Sometimes repetitive or routine problems are involved which are to be verified periodically. So, at the end of all the above managerial skills, you may be able to know the overall skills of a manager. Also, there are different levels of managers – first level managers, having the direct contact with the employees, middle level managers to whom the first level managers report, comparatively less in number than first level managers and top le vel managers who are the overall decision makers of the company.Managerial skills at various levels These skills refer to the ability of managers at different managerial levels of the system hierarchy. Katz in 1974 categorized managerial skills into three types. Technical skill It’s the ability to work with resources in a particular area of expertise. For example, a lab assistant must know his subject well, to help the project students. An accountant should know everything about accounts and balance sheet and a surgeon should be well expert in surgery.In a small manufacturing organization, top boss should have a clear idea of technology skills. Very often, training programs can help employees to expertise in technical skills. Human skill It deals with the ability of a manager to work effectively among his group of members, interact well and take suitable decisions to lead them from front. Communication skill of a manager is very important. Also, to provide a better working at mosphere for his subordinates, a manager is needed to possess certain human skills and it can be developed without any formal training. Conceptual skillIt’s the ability to see organization as a whole and recognizing relationships or links of different modules within the system. Also, it identifies the impact of changes of one module affecting other modules, it may be one or two or a group. As a manager you need to view situations and determine the inter-related factors. Also, his ability to co-ordinate and integrate a variety of factors is very important. Top management skills No doubt, top management has to run the organization as a whole and hence they need some special, distinct management skills to control the whole organization.Most important of them include Building a strong and efficient team of people at the middle management level and should encourage his subordinates to learn some of his management skills as well. Need to monitor and review the functioning of an org anization at different time intervals and check if the outputs are matching the already set targets. Keep in touch and share ideas with planners, policy makers and intellectual and skilled people of the organization. To find competent human resources to fit their organization and encourage and appreciate them in the form of rewards if needed.Develop a distinct and special skill to make you different from others and prompt others to follow you. You can even guide your subordinates by sharing your experiences and piece of knowledge. Thus skills of a manager is essentially two ways – functional, which involves planning, organizing, leading, controlling and decision making and skills of managers involving technical, human and conceptual. Through this article, I have given a brief description of managerial skills needed for an organization.

A Stranger Looking in my House Would Probably Think...

A stranger looking in my house would probably think my life is society’s definition of normalcy: a father, a mother, a daughter, and a son, all living in one house. We eat from the same refrigerator, use the same den to watch television, and swim in the same pool. One big happy family, right? Wrong! Behind closed doors, chaos emerges. Unless you were my friend, or a resident of my town, you probably wouldn’t realize that my parents are in the midst of a hectic and painful process: signing divorce papers. My father resides in a guest room downstairs. My parents take turns with days they choose to look after my brother and me. After all, being in the same room together is not always the most pleasant experience. One could even say that what split my parents apart is the fact that they are complete opposites. Although 50% of marriages end in divorce, in my small town, divorce isn’t that common an occurrence. My mom, being the social butterfly that she is, has made it known, publicly, that she and my father have become separated. One might assume that I might be bothered by this part of my life being out in the open; surprisingly, I’m really not. The truth is, I was never â€Å"Daddy’s Little Girl,† making divorce a not-so-hard pill to swallow. Having been brought up in Russia, my father has a completely different mindset from my mom, as well as me. He is shy, stubborn, and maintains completely opposing political views. These days, my dad and I could go on for hours arguing about President Bush’s actions, and it would be considered normal. If you went back a year or two, the situation with my father would be extremely different. I was always somewhat fearful of him; I would never challenge his opinions, and if he and my mom fought, I would sit in silence. The man who was supposed to be the most positive influence on my life made me think that men were pigs, a nd were allowed to treat women like dirt. Ever since my parents began their split, almost a year ago, I have continued to learn that women should not only be treated with respect, but should demand respect as well as demand to have their own opinions heard. My father’s opinion is not the only one which matters in the divorce court, and he has no right to expect more respect than my mom. Yes, I sound harsh, but I, like my mother, deserve and demand respect. Today, when in a situation with my father, I am able to voice my opinion, because it matters. Sometimes, I actually want to thank him thank him for making me a wiser person, and for making me appreciate my own opinion.

Visual Analysis Survey of Western Art II Essay Example | Topics and Well Written Essays - 1250 words

Visual Analysis Survey of Western Art II - Essay Example The piece of art, Madonna and child are now part of the collection of the Lowe art museum in the University of Miami. Madonna and child is a painting done on a piece of wood thus commonly referred to as tempera on wood. It is believed to have been done toward the 16th century and is approximately 80x60 centimeters. Madonna and the child had been neglected for a few centuries but once discovered it became very expensive. It suddenly rose to twenty two million pounds as per the national scientific department. Lately it is the property of Lowe in the University of Miami after being given off as a gift. Before the 16th century, Italy comprised of many states which spoke different languages, thus a need to stand out was paramount. The Italians soon led the way by speaking about their culture through works of art like paintings. This is how Lorenzo di Credi and other painters and sculptors like Da Vinci, Donatello, Verrocchio, Filipo Bruschnelli and others got famous. The painting Madonna and child talked about Italy’s love and curiosity of religious issues and how they felt about it. It showed that culturally, Italians are a religious nation. The cultural aspect was seen in the technique that most Italian works of art appeared in. for example, Madonna and child was on tempera of wood while other works by other Italian artists were made of oil on wood and such stuff. This article is going to thoroughly survey the piece of art Madonna and child. This it is going to look into from the paintings composition to its characteristics and comparison to other works of art. The composition of the painting of Madonna and child by Lorenzo was due to Italy’s religious passion. During this era Catholicism was widely spread in Italy and its roots were firmly instilled in the people who used sculptures and paintings to bring Christianity and especially Catholicism to reality. Therefore the theme that led to Madonna and child
