The Impact of Ancient DNA Discovered in Siberia Essay -- Exploratory E

The Impact of Ancient DNA Discovered in Siberia For many decades, there has been an overwhelming curiosity about what life was like before humans ruled the earth - back when life on land, off land, and even the very land itself was very different than it is today. Pieces of this puzzle have been discovered all over the world, ranging from perfectly preserved skeletons at the bottom of bodies of water to fragments discovered in vast deserts. Due to the conditions of the ancient finds, there is only so much that can be deciphered about the past, which leads to the creations of various theories of what life was like in different areas and why and when it changed. However, in at least one stretch of land, there is a lot that can be told thanks to one of the best finds in recent history: some of the oldest DNA ever recovered. This amazing find was first reported in April of 2003, when it was told that animal and plant DNA was found in the permafrost of northeastern Siberia (Thomas 2003). The permafrost was located between the Lena and Kolyma rivers of former western Beringia and was drilled out under scrupulous conditions – using extreme care not to let any of the precious samples become contaminated. In fact, strains of specialized bacteria were used to ward off any possible contamination (Willerslev 2003). The event was led by Eske Willerslev of the University of Copenhagen in Denmark (Thomas 2003), who’s international team looked towards drilling for sediment deposits in the layered ice when other areas containing possible ancient DNA samples provided only rare samples that were highly susceptible to extraction and examination difficulties (Willerslev 2003). Fortunately, luck was with the international t... ...nd, oddly enough, the frozen digestive remains of prehistoric animals, important questions have been answered and fierce debates have been settled. This just goes to show that you never know where the next big ancient discovery is going to come from and gives hope for others to keep searching.

Records Administrators and Technicians

Records Administrators and Technicians November 24, 2010 HCR/210 Instructor: Jennifer Briscoe Records Administrators and Technicians The general duties for handling patient records differ between a record administrator (RHIA) and a records technician (RHIT). A RHIT has to have knowledge about medical records and implement the skills that go into filling out all the documents in the files. A RHIA hires and teaches medical record technicians how properly to complete medical documentations.Three specific examples of differences between a record administrator and a records technician are a technician can assist an administrator, an administrator reviews a technician’s work, and an administrator manages or supervises the medical staff at a medical facility. A RHIT has to be knowledgeable in medical requirements, standards, procedures, regulations, and methods. A technician has to know a wide range of medical codes, medical terminology, and medical record content and organization.Al so a technician has to be well-informed in psychology, diseases, anatomical systems, read and comprehend a medical chart, and be familiar with other medical departments. A record technician also has to work with health care insurance. A RHIT has many more specific duties when working with medical records. A RHIT uses many medical record knowledge and skills regularly so they must be accurate with the completed records. A RHIA has to have all the knowledge of a medical record technician because they hire and train the new employees.An administrator only steps into help out a technician if he or she is needed. An administrator also checks a technician work to see if it is complete, accurate, and complies with the federal regulations and facility policies. Administrators are the leaders of facility documentations and develop procedures and policies for the staff. An administrator distributes records when he or she is authorized to by the patients.

Slavery And Its Effects On The Southern Economy - 1212 Words

Ratified by the states in the winter of 1865, the Thirteenth Amendment was put into play. It declared, â€Å"Neither slavery nor involuntary servitude†¦shall exist within the United States or any place subject to their jurisdiction.† (Primary Documents). Officially, this amendment outlawed the practice of slavery, there was, however, an exception. That exception was the use of involuntary servitude, or slavery, as a form of punishment. More than four million African Americans walked free in 1865, this had a rather negative impact on the Southern economy. And so came the Convict-lease system. Many white Southerners saw this system as a solution to their economic hardships; nonetheless, it was often seen as being worse than slavery. In addition to the convict lease system was the practice of Sharecropping and Peonage. These forms of subjugation brought even greater distress to the newly freed African Americans. Despite the ratifying of the Thirteenth Amendment the abhorrent treatment of this newly freed race did not change significantly thanks to programs like the Convict Lease system, Peonage, and Sharecropping. The novel â€Å"Slavery by Another Name† by Douglas A. Blackmon tells of the hardships the newly freed slaves faced, as well as following the life of a young African American man by the name of Green Cottenham. Born in the 1880s to two former slaves, was then arrested for â€Å"vagrancy† in 1908, was leased out by the state of Alabama to work in a U.S. Steel coal mine, where he isShow MoreRelatedSlavery And Its Impact On The United States986 Words   |  4 PagesSlavery dates back to as early as 1760 BC.
