Sediment Core Analysis in Archaeology

Sediment cores are an extremely useful tool used in conjunction with archaeological studies. Basically, a geologist uses a long narrow metal (generally aluminum) tube to sample the soil deposits in the bottom of a lake or wetland. The soils are removed, dried, and analyzed in a laboratory. The reason sediment core analysis is interesting is because the bottoms of a lake or wetland are records of the silt and pollen and other objects and materials which have fallen into the lake over time. The lake water acts as both a sorting device and as a preservative  since the deposits fall in chronological order and (if not subject to dredging) are not normally otherwise disturbed by humans. So, a tube extended down into these sediments collects a sample of 2-5 inch diameter of undisturbed deposits which reflect changes over time. Sediment columns can be dated using AMS radiocarbon dates from tiny pieces of charcoal in the sediments. Pollen and phytoliths recovered from soils can provide data about the predominant climate; stable isotope analysis can suggest plant colony type dominance. Tiny artifacts such as micro-debitage can appear in soil columns. Identifying periods when the amount of soil deposited within a given time increases steeply can be an indication of increased erosion  after adjacent land was cleared.

St. Augustin Essay - 1250 Words

From the analysis of St. Augustine Confessions and Beowulf, it is clear that the two authors, St. Augustine and the poet respectively, differ on their views of death, which helps to paint a better picture of the world that each writer lived in. In Augustines writings, death plays a major role in life; it serves as the stepping stone to a greater existence in heaven. In Augustines world, Christianity and God both play an important role in how death is viewed. In the poets writings we see a different perspective, one in which the time you spend on earth is of great importance; very little thought is given to life after death. Although God is mentioned and discussed throughout the writing, it is a very different perspective than the one†¦show more content†¦We can see this in the passage Our Life himself came down into this world and took away our death. He slew it with his own abounding life, and with thunder in his voice he called us from this world to return to him in heaven (Confessions, 82).; If you were a Christian in Augustines world, death was a passage that one should look to once it arrives, as the joyous return to heaven; not a loss but a great gain. It is clear that death played an important role in the world of St. Augustine. When we look at the world of the poet of Beowulf, we see a very different world. In the world of the poet, life is seen as very important; almost no thought is given to where the soul goes after dying. Making the most of ones life, while you are living, it seems is unparalleled in importance. My father was a noble leader well known among nationsamp;#8230;He lived through many winters, and was an old man when he departed from this world (Beowulf, 10).; Beowulf speaks of his fathers long life and notoriety as if that is all that is left of him. There is no mention of his faith or the transcendence of his soul, as one would come to expect in the Confessions.

Evolutionism Vs Creationism Essay Example For Students

Evolutionism Vs Creationism Essay Creationism is a religious metaphysical theory about the origin of the universe. It is not a scientific theory. Technically, creationism is not necessarilyconnected to any particular religion. It simply requires a belief in a Creator. Millions of Christians and non-Christians believe there is a Creator of theuniverse and that scientific theories such as the the theory of evolution do notconflict with belief in a Creator. However, fundamentalist Christians such asRonald Reagan and Jerry Falwell, have co-opted the term creationism and it isnow difficult to refer to creationism without being understood as referring tofundamentalist Christians who (a) take the stories in Genesis as accurateaccounts of the origin of the universe and life on Earth, and (b) believe thatGenesis is incompatible with the Big Bang theory and the theory of evolution. The science of paleontology or the study of life provides the most direct proof of evolution in the past through fossil remains or impressions, usually in rock. Other evidence comes from comparative studies of living animals and plants, including their structure and geographical locations. Mollusks and vascular plants account for more than 80 percent (Futuyma 87) of the worlds species, with about 1.4 to 1.8 million species (Futuyma 87) in all. Changes occur in living organisms to help increase their adaptability, or potential for survival and reproduction, in the face of changing environments. Evolution apparently has no built-in direction or purpose. A given kind of organism may evolve only when it occurs in a variety of forms differing in hereditary characteristics, or traits, that are passed from parent to offspring. By chance, some varieties prove to be poorly adapted to their current environment and thus disappear, whereas others prove to be adaptive, and their numbers increase. The elimination of the unfit, or the survival of the fittest, is known as natural selection because it is nature that discards or favors a particular variant. Basically, evolution takes place only when natural selection operates on a population of organisms containing diverse inheritable forms. Creationists have gone back to the basic laws of nature to see if evolution is physically possible given enough time and opportunity. The one major pro blem that they see is the 2nd Law of Thermodynamics. It states, All natural systems degenerate when left to themselves. This is why everything falls apart and decays over time. Creationists point to death as being the ultimate manifestation of this law. This physics principle does not allow for something as complex as the human eye to originate from something simple. The eye must follow the tendency for complete degeneration. Creationists see a downward spiral for every living and non-living creation. Everything breaks down into simpler substances; they do not become more complex. Creationists say that, in the real world the long-term flow is downhill, not uphill. An experimental and physical observation appears to confirm that the law is indeed universal, affecting all natural processes in the long run. Sir Gawain And The Green Knight EssayThe evolutionists do not see the Second Law of Thermodynamics as a contradiction to evolutionary processes, because as it specifically states that the entropy of a closed system cannot decrease. The law pertains to closed systems. The earth, and therefore evolution, is not a closed system (Creation Science FAQ) As we know, there are no closed system on earth, so in no way can any living system on Earth directly violate the second law (Creation Science FAQ) Therefore, this argument is invalid. The age of the universe, perhaps billions of years old, shows that life has had lots of time to evolve from single celled organisms to what we are today. Through fossils, and other evidences, it shows that humans came from primates, which is not surprising, since we are almost physically identical to a chimpanzee. In the beginning, very simple life forms began gradually appearing. These simple life forms gradually changed to complex ones, and there have been transitional links between the different kinds, such as fishes and primates. They both have the same types of bones, for example, forearms, wrists, elbows, upper arms, and shoulders. They seem to be related to a common ancestor. The Bible says that an omnipotent being, created the earth and everything on it in 6 days. He also created everything out of nothing. This is literally impossible, it challenges all physics laws, so it cannot be done. The only proof that Creationists have of the origin of life is the Bible. Evolutionists have much more proofs or evidence of how humans appeared on the earth. The Bible, whether intended literally or figuratively, is definitely an important piece of literature. To believe that the age of the earth is only 10,000 years old does not support the validity of the creationists. To many scholars, the Bible is a figurative book of parables, not to be taken literally. The use of the Bible may be hindering, instead of supporting, the validity of the creationists arguments. It is clear that evolution is much clearer to understand and accept than the creationism theory. There will always be people who will still be curious as to how we appeared on the earth, and some people will oppose the evolution theory, therefore, the evolutionism/creationism debate will forever continue.

JVA Corporation Simulation

In analyzing the current position of JVA Corporation and its future performance projections, the best strategy to employ so as to save and preserve the overall net profitability of the company is reviewing the corporation’s performance and revenue after every six months. Under this strategy, the corporation will either increase or reduce the employee pay and review their performance after six months (Noe et al 2010).Advertising We will write a custom essay sample on JVA Corporation Simulation specifically for you for only $16.05 $11/page Learn More The corporation’s employees will get a pay increase twice a year depending on individual performance, if the strategy is adopted, unlike the current strategy where employees with satisfactory performance are compensated once in a year. Employees who do not perform will have their compensation package subsequently reduced twice within a year. This will encourage the employees to work hard and impr ove their performance since; none of them will wish to have their individual pay reduced (Noe et al 2010). The strategy should be in place for a period not exceeding a year given the expected improvement in the performance of the JVA Corporation. It is expected that after this duration, each employee will have improved their performance and thus leading to an upward compensation during the package review. After attaining the required performance standards, it will be wise for the corporation to switch back to annual pay review (Noe et al 2010). The half- year pay and performance review strategy will be applied to both employees within and outside the United States. This is because a very small fraction of the international employees are the managers, who are entitled to a full time salary. Out of the 185,000 corporation employees, 3,500 are management staff employees. This shows that they take a very small percentage of the wage bill to achieve the overall objectives of JVA Corporat ion. However, the review should be based on the location of the employee since the product market trends differ from one geographic region to another. Proper implementation of the strategy will benefit the corporation in several ways as the corporation will be in a position to evaluate its performance half way through the year. Therefore, it will be able to adopt new performance approaches or continue with the existing ones. The corporation, will also save the cost incurred in compensating employees whose performance are unevenly distributed within a year; those that perform highly either in the first half of the year or the second (Noe et al 2010). The result will be a motivated and improved performance by employees throughout the whole year since each employee will target a double upward pay review. As mentioned earlier, the corporation should swiftly switch over to annual review once the required set standards are attained. In this regard, JVA will be in a position to save a lot from downward pay review on underperforming employees during the initial implementation of the strategy (Noe et al 2010).Advertising Looking for essay on business economics? Let's see if we can help you! Get your first paper with 15% OFF Learn More On switching over to the annual review, again substantial savings will be made since the compensation packages; earlier paid twice in a year will be available once a year but with same or better performance standards. The strategy is bound to have subsequent effects on the community if adopted. The double pay review will encourage more people to seek employment in the corporation, especially the temporary staff. The motivation given to the employees will automatically lead to better and improved product quality. The community members also stand a chance of getting more job opportunities should the strategy lead to expansion of the corporation, as a result, a need for more labor force. In conclusion, the strategy will be the best remedy for the upward revival of JVA Corporation’s overall profits (Noe et al 2010).

Expert Interview with Rita Friedman on Revitalizing Your Career

Expert Interview with Rita Friedman on Revitalizing Your Career If you’re at a dead end in your career, Rita Friedman can help. As a job coach and career expert, she helps job hunters find the career right for them at Philly Career Coach. She spoke with us about finding a job and keeping it. What form does career coaching take?Career coaching can take a range of forms, and career coaches use varied techniques, but it’s basically a worker / job seeker and a coach working together to develop career plans. Typical topics can include trying to figure out which jobs to target, how to navigate job boards, what to say (and not say) on a resume, interview prep, salary negotiation, managing the transition to a new role, establishing career milestones and strategizing for longer term growth.Why are career coaches more important than ever in the current job market?The job market has become increasingly complex – sometimes a job seeker doesn’t even know how to look for good information or opportunities; sometimes there’s ju st so much to sift through†¦. But even an experienced person can use an objective third party to create a sense of accountability and provide support.How have changes in the economy affected job seekers? What do you find people are looking for in a job?The recession really shook things up in a lot of ways. Of course, a lot of people lost their jobs; others who survived layoffs often had to assume additional responsibilities – that instability created a lot of fear, and I think it also decreased employee loyalty. But it also showed people there are other ways to work, including holding multiple positions concurrently or taking on some freelance work. I see more people looking for work they find meaningful, maybe in part because if the idea of stability is shattered, people feel they might as well go after what they really want to be doing anyway. I also see job seekers evaluating potential employers’ stability and shying away from companies they think are likely to restructure.What can job boards do to better find the job seekers they need?Job boards have gotten more sophisticated recently, and a lot of them have gotten pretty good at organizing information so job seekers can sort through a high volume of postings. Niche boards hold a certain appeal and can create a loyal base. In terms of functionality, it absolutely has to work across all platforms – a lot of people want to apply from their phones or iPads. Transparency is always a big turn-on for job seekers who like knowing who posted a job, how long it’s been listed, how many people are in the running and if a job posting appears because it’s sponsored. Providing links to actually relevant info – not just filler content – and serving as a knowledge bank can attract and keep visitors. And a good job board is easy on the eyes – sleek and instantly navigable. And each job board should have its own flavor – it’s not enough just to look good; there has to be some reason why it stands out.How can employers write postings to attract the applicants they’re looking for?Be specific. If something is really non-negotiable, make that clear in the posting. If there’s a definite salary attached to the role, including it in the job posting can help filter out the wrong candidates. Including mention of any special perks – such as the ability to work remotely, flexible hours, a generous vacation policy – can make even a boring job sound exciting. Be sure to include keywords so that job seekers can find the listing from searching beyond job titles. Do show some personality or company culture, but don’t write a flashy or sassy job posting if it’s not in line with the actual work environment.How are careers changing? What will employment be like in the future?One of the biggest changes we’ve seen in the employment landscape is a broader range of ages in any given workplace – from college students completing mandatory internships to workers retiring later in life, or even coming out of retirement to return to the workforce. And with people working for so long, we’re going to continue to see people who switch careers multiple times during their professional lives. There’s also a move towards portfolio careers, where an employee is likely to have a couple of part-time jobs instead of one full-time position. Finally, employees want flexibility more than ever, and even though most people still want to be part of a great team, autonomy seems to be especially valued by workers right now. People want to use web-based technologies to work on their own terms – and companies are starting to realize they actually get more out of their people as a result.

The general characteristics of Temple Architecture Essay

The general characteristics of Temple Architecture - Essay Example One of the key characteristics of ancient temple architecture was their dedication to a deity. Most of the ancient temples were built as a dedication to the gods that were worshipped in those times. The Roman temple of Fortuna Virilis is also referred to as the temple of Portumnus because it was in dedication to the Roman god Portumnus, the god protector of the harbors and trade at sea (history of roman). The Greek temple of Poseidon in Paestum, Italy was also a dedication to the Greek sea god, Poseidon and even had a massive statue of him in its main hall (Cape Sounion,2008). While the temple of Amenhotep was largely a dedication to his father amen, the northern part of it was dedicated to the Egyptian god Osiris (Andrews, 2005). The Mesopotamian white temple was built at a very high place, on the ziggurat platform, because the people of Mesopotamia believed that it was in high places that their god would visit the earth (Sumerian Art). Thus as part of their architecture, most of th ese temples had statues that represented the deities to which they had been dedicated All temple architecture was inspired by religious beliefs but perhaps none portrays this so much as the Egyptian Temple designed by Amenhotep the third during his reign. This is the largest temple to ever be built in Egypt. It boasted 385,000 square meters coverage and was built in such a manner that it could flood when the waters of the Nile rose, leaving only the inner part dry. This was based on the religious belief that when the water level went down, the re-emergence of the temple would signify a sort of rebirth of the world, like in the time of creation (Andrews, 2005). The Greek Poseidon temple was also based on the religious belief that since Poseidon was the sea god and the temple was located near waters then it would only be fitting to dedicate it to the sea god in order to win his favor (Cape

Identification of novel human cancer-specific antigens Literature review

Identification of novel human cancer-specific antigens - Literature review Example   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Likewise, opportunities to develop cancer treatment demonstrated promising results (Haffner et al., 2001; Jager, Jager, and Knuth, 2002; Fijak and Meinhardt, 2006; Park, Lin, Nishidate, Nakamura & Katagiri, 2006;   Tabi and Man, 2006;   Ã‚  Hayashi et al., 2007; Meklat et al., 2007; Dakshinamurthy, Ramesar, Goldberg and Blackburn, 2008; Hunder et al., 2008; Old, 2008; Caballero and Chen, 2009; Chen et al., 2009; Dubovsky et al., 2009; Fard and Modaressi, 2009; Vujanovic and Butterfield, 2009). Consequently, pioneering research in the search for effective cancer vaccines has produced cancer/testis antigens such as MAGE, GAGE, and NY-ESO-1 which are currently undergoing clinical trials (Mashino et al. 2001; Bowlus, 2007; Gierstoff and Ditzel, 2008). Each year more cancer/testis antigens are being identified, creating more opportunities for research and increasing the chances of developing cancer vaccines that can be used not only for treatments, but for prevention as well (Jager, Jager, and Knuth, 2002). Also, research on cancer/testis antigens has brought to light important discoveries on how mechanisms of cancer development work at a molecular level (Alters, 2000; Old, 2001; Gjerstoff, Kock, Nielsen and Ditzel, 2007; Delbridge, 2010; Inagaki, Schoenmakers and Baarends, 2010; Suzuki et al., 2010). Moreover, studies on the link between chromosomes and immune responses reveal that some cancers are more prevalent in males than in females. In addition, results also show that females may have higher cancer survival rates but are more susceptible to autoimmune diseases (Libert, Dejager and Pinheiro, 2010). Further research on the role of cancer/testis antigens should be conducted, particularly in determining the mechanisms that initiate cancer in the first place. Also, further studies should be performed to developed better cancer diagnostic methods and combination immunotherapy
