An Evaluation of Two RAD University Tutorials Research Paper

An Evaluation of Two RAD University Tutorials - Research Paper Example The tutorial on MPLS and Network Convergence is about the concepts and applications of network components such as the routers and switches that implement the protocols which play critical roles in supporting higher volumes of internet data in a faster way (MPLS, 2009). It initially provides all the information required to understand networking concepts such as traditional routing and packet switching, label switching, the IP over ATM model, and then the basics of multilayer switching and the multilayer switching solutions. All of these are written in text, explaining in details how each component is necessary to carry out networking of bulk of data using the evolving models until the multilayer switching. The concepts of difficulties encountered before MPLS was employed are also discussed, together with the complexities of the executed initial solutions. It mentions that the emergence of multilayer switching solutions and MPLS is part of the evolution of the Internet to decrease comp lexity by combining Layer 2 switching and Layer 3 routing into a fully integrated solution (MPLS, 2009). The tutorial is very comprehensive in explaining what is required to be understood in terms of the MPLS technology. This time, the developers created a simple version of it through a flash slide presentation that includes visual media composed of pictures and symbols that convey the complex systems in the most simplistic way. This is more effective in delivering the networking capabilities of MPLS. The tutorial further discusses the types of a problem this the technology solves and other opportunities for its use. The tutorial can be very much appreciated by a network technician or an individual who has practical applications on network technologies. I believe the ideas are more easily understood once you are involved in a networking environment. The diagrams created by the developers to illustrate their point regarding the use of IP over ATM Model and the problems when it is ado pted are very useful for the reader to comprehend the networking systems in this manner.

Visual Literacy in Business Essay Example | Topics and Well Written Essays - 500 words

Visual Literacy in Business - Essay Example Simply, Kennedy’s definition is more concerned with the action of seeing and deriving meaning from visual images while Howell’s definition is more concerned with the cognitive processes involved when people retrieve meaning from visual images and how experiences, sensory perception and critical thinking affect the process (Howells, 2009). I am of the opinion that Howell’s definition offers a better and more comprehensive analysis of visual literacy since it not only analyses the physical action of seeing images, but also identifies that it encompasses other factors such as the cognitive processes specific to a person, such as their attention span, experiences, reception to external stimuli and their ability to think critically. I find Kennedy’s evaluation limiting and lacking since it only emphasizes on the physical activity of seeing as the primary and sole factor in the process of retrieving meaning from images. Kennedy’s definition alludes to the fact that visual literacy is straight forward for everyone. However, this is not the case especially in today’s world where conditions such as attention deficit disorders may inhibit the ability of a person to accurately decipher the meaning of images and consequently impact on the visual literacy of a person. In today’s world, the classroom offers an opportunity to study and recognize the different levels of visual literacy among people. According to Elkins, the most compelling argument in favor of visual literacy being considered as a universal language is its ability to communicate messages, concepts and ideas to people of varying cultural languages across the world. The use of one image may be used to convey a singular message to people of diverse cultures and languages across the globe and despite the differences, the people will still retrieve a singular meaning to the visual image presented. Essentially, visual literacy is not

Grafting Term Paper Example | Topics and Well Written Essays - 1500 words

Grafting - Term Paper Example Grafting of appropriate plants result in improved hardiness in plants, hardiness refers to the ability of a plant to endure harsh climatic conditions. Through successful grafting for example, the showy Western Australian plants currently can resist the heavy soils common in urban centers (Core, 2005). Grafting has succeeded developing appropriate plants that fit different ecological conditions prevalent in different parts of the world. As discussed earlier, grafting conjoins two unique plants together thus resulting in the development of a unique new species. The resultant species benefits from the productive features of both the stock and the scion. In most cases, the stock always provide effective adaptive features of the root to enable the new plant survive in particular conditions while the scion provides effective foliage and flowing features that improves the productivity of the resultant plants. Precocity is a unique ability introduced only through grafting. It refers to the process of inducing productivity in plants without necessarily undergoing the juvenile stage. Introducing a scion in a stock disrupts the growth patterns of the resulting plant. Among the major advantages of the disruptions is that most of the plants bypass juvenility a period of growth and maturity in the plants. By passing the stage, the plants immediately begin producing fruits. This increases the profitability of agribusiness by shortening the time that fruit plants take before becoming fruitful. Bypassing the stage of juvenility is fundamental in agribusiness owing go the length of the duration, juvenility may last up to nine years in different plants. Bypassing the stage safeguards the quality and productivity of the plants since the new plat is likely to perform better than the two parent plants while doing so within the shortest time possible.

Interview with a group of adolescents - Essay Example They said they were glad they were young and didnt need to worry with things like that. They also agreed that being young was great because they didnt need to work a full time job. Some of them had casual jobs they did for their own spending money, but they realized that they didnt need to go to work every day like their parents. This line of discussion lead naturally into what they didnt like about being a teenager. They expressed frustration about the lack of freedom they had. They were forced to go to school, eat the food prepared for them at home and wear the clothes their parents bought for them. They didnt like the fact that they were required to go to school, but most of them agreed that school was more fun than it was work so they didnt mind being there. All of them agreed that not being able to drive a car yet was a pain. They all looked forward to getting their drivers licenses and seemed to think that being able to drive would solve most of their problems. Life would be so much better after age sixteen. I can commiserate with these kids as I remember being a teenager. There was a conflict that seemed to intensify each year until age sixteen. On the one hand I felt I deserved more freedom, but on the other hand, there was no real way for my parents to grant that freedom until I could drive a car. I remember feeling exactly like these kids. A car would change everything! I received lots of different answers about what was the best thing in life right now for these kids. Interesting enough, most of the answers for both best and worst aspect of life dealt with some sort of interpersonal contact within the family of the peer group. Some of the kids said the best thing in their life right now was their girlfriend or boyfriend. Three said that the worst thing was that they had just broken up with their boyfriend or girlfriend. One girl

Skiing Essay Example | Topics and Well Written Essays - 750 words

Skiing - Essay Example In USA, the first record of the use of skis was in Wisconsin in the year 1841 with the first ski race being held in 1867. Other famous events in the ski history in the US were held in the 1930s in locations such as Utah, Idaho, Stowe, Sun Valley and Ulta among others. Recreational skiing, which is the most popular type, has been traced to have originated in the Scandinavian countries with Norway being the location where it was most used. Initially, skiing was used as a method of movement (travel) as used by hunters across the snow-bound regions. In this period, steering and stopping techniques were developed while also various types of skiing such as Alpine and ski jumping were established as well. With the migration and traveling of the Norwegians around other parts of the world, there was an emergence of skiing as a sport. 1n 1924, the first Winter Olympics were held in Chamonix, France where skiing sport was part of the military competitions. During this time, the ski equipment was greatly improved while the transportation devices for carrying skiers were also developed. With a growing interest in the recreational activity, there was an emergence of ski resorts largely in the urbanized areas. By the World War II, skiing sport had grown into a large industry that went beyond the traditional hardcore group such as the college club students and ski jumpers. After the war, the skiing industry experienced a rapid growth that was characterized by an increase in the number of ski areas and an improvement of ski equipment among others. The Winter Olympic games of the year 1960 were televised, making the sport more popular among the American population. The post-1970s years have seen a continuous growth of the sport that has seen the skiing industry become what there is in this day (Goeldner & Standley, 105-106). Today, there are numerous types and styles in which the sport enthusiasts enjoy it.

Film Analysis Essay Example | Topics and Well Written Essays - 1000 words

Film Analysis - Essay Example He joined a Neo- Kazi movement where he befriended the leaders of that group, and started his mission with rage. When in the movement he killed two black men who were members of the gang. Before he killed them he found them trying to break into the truck that his father had left for him. Later he was imprisoned for three years as a result of manslaughter. As the film starts, there is a flashback, where Danny is trying to get some sleep but he cannot sleep because he was disturbed by the noise coming out from his brothers’ room. The brother was having sex with his girlfriend. He then hears another voice from outside, when he peeped through the window he saw a black man who was trying to break into his brothers’ truck.

After that incidence Derrick is sentenced for three years imprisonment. I n prison, he was raped by the fellow skinheads but later was befriended by a black man whom he had to work for, just for his security in prison. The experience that Derrick went through, when in prison changed him forever. On his return home he realized that his younger brother Danny had started to involve himself with the group of white supremacy. Danny was spitting the racial slurs right and left, the same way that Derrick used to do before he was imprisoned (Smith, 2007). Derrick was in dismay when he realized that his family was torn apart, due to his violent action. Immediately after his release he goes to try and see if he can bring the family together. He wanted to reconcile with his sisters and mother, and also to change Danny from his behaviors that were disturbing. Towards the end of the film, it was clear that Derrick was able to change Danny to be the boy that he ones. To distance themselves from the white supremacy the boys had to tear down the pro-Nazi and racist propa ganda that were on the walls in Danny’s bedroom.

Another emotion of incivility is by that instance in the film American history, where Danny was shot by a black (Parfit, 2008). This boy killed him because he was filled with hatred against the whites. The other incidence that shows incivility is when Derricks’ father was murdered by a black man who was a drug dealer. When Danny died Derrick ran to him and started mourning as he asked himself what he had done that led to his

Liver Transplant Essay Example for Free

Liver Transplant Essay Organ transplants are some of the hardest surgeries that doctors can do. They require many trained personnel, time, and complicated procedures. Liver transplants are among the most difficult organ transplants that can be done. There are also many risks involved with the surgery and patients must face all of them in order to come out with a new and working liver. According to the American Liver Foundation patients that undergo a liver transplant have a 75% chance of survival after five years. In other words, one in four patients will die in five years due to their new liver. Even for organ transplants, that is a very low chance of survival. Organ transplants tend to be very complex in nature. Since livers have so many functions they are among the hardest to transplant safely. The surgeon must first make a cut in the upper abdomen. Then they must remove the old liver by cutting it off from the blood vessels and bile ducts. The surgeon must then place the new liver into the patient’s body and connect it to the old blood vessels and bile ducts. Most operations usually take around 12 hours and since there is so much blood lost new blood must be continually added through a transfusion for the whole of the operation. There are many problems with this surgery and the first one is the act of moving the donated liver to the patient that will receive it. The liver can only stay functioning for a short period of time outside of the body. That means that as soon as a liver is taken from a donor it must be immediately transported to the recipient. This requires that many people work together as one to set up an appointment for the patient and the donor, to remove the liver from the donor, ship the donor’s liver to the recipient, put the liver into the recipient, close them up, and manage the finances of the whole operation. All of this requiring much time, effort, and money. There is yet an even larger risk that the new liver might be seen as an invader of the body by the immune system. This would mean that the body would start to break apart the new liver and attack it with cells that were made to fight off disease. The immune system would essentially be fighting off the thing trying to help it. Unfortunately all transplant patients also become dependent on immunosuppressive drugs that keeps the immune system from attacking the liver. While these drug may be helpful they also keep patients from fighting off infections, so all patients have a harder time fighting off disease. The patients must also use these drugs for as long as they live, adding up to thousands of dollars over the patient’s life. Luckily there are many new procedures that will make the chance of survival even higher. For instance, doctors can now take a small piece of a living donor’s liver and graft it onto the recipient’s liver. This can be done since the body only needs a small part of the a liver to carry out its normal functions, things like transporting the bile from the gallbladder to the intestines and detoxifying the blood. The procedure usually has to be done with donors and patients that have the same blood type and other major body factors. This means that a surgery is usually done with members of the same family. Another great thing for liver transplant patients is a new liquid that organs can be placed in for transportation. It keeps the organ as fresh as if it were inside the body. This allows the organ to be moved much farther than it would have otherwise. Instead of it being moved just 30 minutes away it can be moved across the country. But even this is not perfect, even in this liquid organs can still break down and fail to work inside of the new body. In the end, the benefits of liver transplantations far outweigh the risks for only one reason. Every patient will die if they do not receive a new liver.
