Reflection - Essay Example Consequently, the system administration department enhances the prevention of system garbage issues. Garbage (errors) that enter the system will generate garbage outputs. If the wrong math program or number enters the system, the system will produce a wrong math solution or output. Entering the wrong student name in the database will generate avoidable erroneous student –related outputs (Burgess 690). Further, there is a major relation between the human rights class subject and system administration. The system administration personnel interact and communicate with different individuals within and outside the system administration arena. The subject will teach the affected personnel to respect the human rights of the other employees. The subject warns the system administrator and his staff of employees’ gender, age, and other discrimination lawsuits (Gross13). Furthermore, there is an important relation between the environment class subject and system administration. The system administration employees learn to implement the anti-pollution laws. The system administrator must not throw his department’s waste papers into the nearby crystal clear lake, polluting the lake. Similarly, the system administrator should never burn waste paper, polluting the vicinity’s air (Friis 258). There is a noteworthy relation between the globalization class subject and system administration. The class will equip the system administrator and other subordinates with globally-necessary tools. The tools will improve the computer-based systems administrator’s production output. With the incorporation of the latest trends, the administration’s outputs will be at par with other globally recognized system administration departments’ outputs, concerns, goals, tasks, and responsibilities (Bailey 244). There is an influential relation between the self

Clovis People Essay Example for Free

Clovis People Essay DNA harvested from the remains of an infant buried 13,000 years ago confirms that the earliest widespread culture in North America was descended from humans who crossed over to the New World from Asia, scientists say. The research, detailed in this weeks issue of the journal Nature, also suggests that many contemporary Native Americans are direct descendants of the so-called Clovis people, whose distinctive stone tools have been found scattered across North America and Mexico. The origins and genetic legacy of the people who made Clovis tools have been topics of debate among scientists. While most archaeologists think that the Clovis people were descended from Asians, an alternative theory suggests that the Clovis ancestors emigrated from southwestern Europe during the Last Glacial Maximum more than 15,000 years ago. The new findings strongly refute that idea, known as the Solutrean hypothesis, said study co-author Michael Waters, director of the Center for the Study of the First Americans at Texas AM University. This shows very clearly that the ancestry of the very first Americans can be traced back to Asia, Waters said. David Anderson, an anthropologist at the University of Tennessee Knoxville, agreed. Theres been a standard model for a long time that modern Native Americans are descended from populations coming from East Asia a few thousand years before Clovis, and thats what this finding reinforces, said Anderson, who was not involved in the study. Anthropologist Dennis Jenkins of the University of Oregon said the new study was a really important and really well done piece of research that opens the door for new kinds of genetic comparisons among ancient Native American remains. The importance of this cannot be overemphasized, said Jenkins, who also did not participate in the research. People have often asked me whats the relationship of the Paisley Caves—a site in Oregon where human feces and artifacts up to 13,200 years old have been found—to Clovis, and Ive always said that would be really nice to know, but there hasnt been any Clovis DNA until now, he said. Oldest Burial in North America. The skeleton of the Clovis child—which experts determined belonged to a young boy about one to one-and-a-half years old—was discovered in 1968 in the Anzick burial site in western Montana. Dozens of ochre-covered stone tools found at the site were consistent with Clovis technology, and radiocarbon dating revealed that the skeleton was approximately 12,600 years old. The Anzick skeleton is the oldest burial in North America, and the only known human burial associated with the Clovis culture, Waters said. Photo of the site where the artifacts were found. † width= PHOTOGRAPH BY MIKE WATERS The earliest known North American burial was found here in western Montana. Using bone shavings collected from the skull, the scientists painstakingly reconstructed the full genome of the young Clovis child. It was actually quite a big challenge, said study leader Eske Willerslev, an evolutionary biologist at the University of Copenhagen in Denmark who led the sequencing effort. Only 1 to 2 percent of the collected DNA was human, Willerslev said. The rest of it came from bacteria that invaded the skeleton after death. Comparison studies of the ancient DNA showed that it was similar to the genomes of ancient people living in Siberia and the ancestors of East Asians. The team also discovered a deep genetic affinity between the boys genetic material and those of 52 Native American populations living in South America and Canada. The Anzick remains share a common ancestry with almost every modern Native American group that we looked at, Waters said. This is an incredible result, Willerslev said, because it suggests that the relatives of the Anzick child were the direct ancestors of most Native American groups living today. This would be possible, he added, if the population of humans living in the New World about 13,000 years ago was very small and every member was closely related to the others. The scientists say they strongly suspect, but cannot yet prove, that Native Americans in the United States are also closely related to the Clovis people. Native American groups in the U. S. have been reluctant to share their DNA, or the DNA of their ancestors, with scientists. Unfortunately, we dont have much genetic material for native people living in the United States, Waters said. If you look at the genetic map [of humans around the world], the U. S. is a big [blank] spot. Jenkins of the University of Oregon said he hopes the new study will lead to further collaborations between scientists and U. S. Native American groups. That trust has got to be developed, and thats where Willerslevs group really excelled, Jenkins said. Well be better anthropologists and scientists if we view these remains more as the remains of people rather than just artifacts.

Windows NT and Linux :: essays research papers

Windows NT and Linux: An inside look and comparison! One of the many challenges of a corporation, small business or educational institution is how to network the people within and outside the organization. Linux and Windows NT are two network operating systems that suit this purpose well, each having its respective advantages and disadvantages. One organization (Nichols College), began utilizing each operating system for two very different purposes. I will explain the function of the two operating systems and how well they each performed for Nichols. Windows NT  Advantages and Disadvantages  Business with Windows NT Linux  Advantages and Disadvantages  Linux in the Business World  Conclusion: Windows NT or Linux? Windows NT: Its Pluses and Minuses Windows NT (New Technology) is an operating system made and offered by Microsoft. Microsoft first released Windows NT in 1993. The basis of Windows NT is an operating system that controls basic computing functions, such as manipulating files. It is a "multipurpose server operating system that delivers a fully integrated file/print and server environment." Windows NT offers one of the highest levels of compatibility with other operating systems and hardware. It was created to be the most integrated, extensive, and easy operating system and it comes in two ways:  For desktop PC's  For server computers (supporting computer networks). Windows NT has both positives and negatives. Some of the advantages include: Integration Performance Reliability Security Manageability Internet Access. Windows NT Server allows all applications to be utilized from the Windows NT Directory Service or NTDS. This has a network logon to all servers and services that it provides and its advantage: Only one user database is needed for the whole system. Windows NT also allows integration with other hardware and operating systems; and files and applications from other servers such as Unix and NetWare. This gives users the ability to install Windows NT knowing that it can fit with their current network. The performance for Windows NT: It runs applications faster, especially 32-bit applications. It is also faster than Windows 95 on 32 MB machines or more. Window NT provides graphical user interfaces (GUI). Definition of GUI - designs used as symbols that make a function visible to the user quicker than having to look for it. As far as reliability, Microsoft has a clustering middleware, named "Wolfpack" that provides fault-tolerant clustering on mainstream PC server hardware. ****Windows NT also provides memory protection and preemptive multitasking, a journalized recoverable file system, and RAID striping with parity.

Accutane associated Depression

Acne vulgaris or acne as it is commonly known, is a common skin disease mostly found in adolescent teenagers above the age of 14 and at times it may extend through to adulthood.According to the Dermatological disease database, acne develops as a result of secretions of the skin sebaceous glands and blockage of skin follicles which leads to eruption of pimples, blackheads and scars on the skin1.   It is not caused by eating certain foods such as chocolate, French fries or pizza as commonly believed.It has been reported by the British Dermatology Journal that, although not much data on acne's epidemiology is available, it has been discovered that about 40 to 85% of teenagers are or have already been affected by this disorder, making it the most common skin disease.For instance in America, every one out of three teenagers is or has had this disorder and the disease prevalence is not dependent on the race, sex, skin color or ethnicity.This disease occurs earlier in females than in male s a fact which can be attributed to the earlier onset of puberty and maturity in females than in males2.   On the contrary, the severity of this disease is more in males than in females especially when it occurs during the late teenage years due to androgen hormonal influences.In adulthood, acne is more prevalent in females than in males.   Some studies have further indicated that the prevalence of acne can be seasonal especially in women where it occurs just before the onset of their menstrual periods.More over, acne has been found to be more severe during the cold seasons than in the warmer weather conditions although these findings are not yet proven.   Some epidemiological data released by the Dermatological department of Munich University suggests that there is a close relationship between smoking and acne prevalence although still, this has not been confirmed3.Background Information.The history of acne disease dates back to ancient days and its origin is believed to be s omewhere in ancient Greece where people infected by this disease were treated using hot water baths mixed with sulfur4.   This method of acne treatment was used all through the 19th century till early 20th century when Benzoyl peroxide treatment was discovered.In 1950s, the use of antibiotics to treat the disease was invented especially tetracyclines although such antibiotics are no longer effective due to resistance of the disease causing germs.   More powerful antibiotics such as Retin-A were later discovered in 1960s and the disease control became much easier.   Such antibiotics are still in use especially in the U. S5.In 1980, the famous Accutane anti-acne drug was invented and this drug although controversial, it is very effective and is still in use today.   The year 1990 saw the emergence of Laser therapy which not only treats the disease but it clears the scars as well.   This treatment is quite expensive although it is very fast and effective.In 2000, the blue/red therapy was invented and this combined with the laser therapy invented earlier, led to more improved methods of acne treatment6.   This evolution shows how acne treatment has evolved with time, making the disease more manageable and easily treatable4.Acne prevalence has been on the decline in the past few years mainly due to increased knowledge on the disease, improved methods of prevention and treatment and better management of the disorder7.

The panama canal

Since the United States began to feel an upcoming conflict with Spain, we were prepared to go to war. They decided to send the US Oregon from California to Cuba only there was one issue.. The voyage would take over 60 days and 14000 miles to land on Cuba. Not only that but in this process the US Oregon had to stop in South America multiple times to fuel up on coal. At this point the U. S new it was time for a change. They found a way to cut their voyage nearly in half by making a canal that connected the Atlantic to the Pacific.This makes transporting goods, and essential supplies a much quicker process. Incidents leading up to the event†¦ The French were really the masterminds behind this constructions. They started the entire process towards making the canal but in the process, they ran into some issues and went bankrupt. Later on the U. S decided to pick up were the French left off. After getting everything approved in the U. S, Colombia denied us of any right to the property on which the construction was being done. This led up to the Panamanian people rebelling and winning their independence. This now allowed theU. S to finally get a start on completing the canal. What occurred during the construction? The construction finally began in 1904 with over 40,000 workers on the construction site. These workers had to deal with not only Jungle weather but as well as all the dangerous Jungle wildlife there was out there. There was very high temperature, unstable land, and very frequent rain. Sometimes if would rain so often that the river would flood; making construction very difficult. Therefore they built a dam to help with the over flow of water and this defiantly but them back on track with the construction.Despite the numerous accounts for trying to make work conditions safer, over 5,000 workers died due to diseases and accidents on the Job. Results of the Canal†¦ The construction of the canal cost America over $375 million dollars, only now their v oyage was only 40 miles to their destination. They cut the trip by 8,000 miles which is more than half of watt it would have been before. This canal helped the U. S move about much quicker and we had the full support of Latin America. Although in 1914 (official opening) the canal was guarded by the U. S military, it now belongs to the Panamanian but is still used as a trade route for the U. S.
