Manned mission to Mars - Essay Example Moon is the natural satellite of earth which is located near to the earth compared to other planets. Only Neil Armstrong and Buzz Aldrin were able to land on moon so far even though many other satellites were send to moon for explorations. The access to moon is still not easy for the humans. Under such circumstances manned missions to Mars has made lot of controversies. Some people argue that manned missions to mars are the only way to find more things about our neighboring planets and to explore the possibilities of any life there. Moreover, only manned missions will be able to prove beyond doubt that how useful the external planets for human beings. On the other hand, critics believe that manned missions to mars is a risky topic because of the immense possibilities of danger both on the way and while landing on moon. This paper briefly analyses the arguments in favor and against manned mission to mars Critics of manned mars mission have raised three major questions; a) how to get funding?, b) how to land on Mars safely?, and c) how to ascent from Mars safely? (Heinonen). It is not easy to send manned spacecrafts to mars. Billions of dollars are needed for mars exploration. It is practically difficult for a single country to bear such huge expenses. But somehow if we are bale to manage the expenses for manned mission, the second question is how to land safely on mars. We have less knowledge about the atmosphere and others dangers waiting for us in Mars. Even the landing on moon was not easy for us even though we did succeed once. Many people believe that high energy cosmic rays and other ionizing radiations might be available in Mars. Moreover, mars have low gravity than earth which may cause further problem to the explorers. The third major cause of concern about manned mars mission is the question of how to ascent from mars even if we succeeded in landing safely on mars. On the other hand,

Modeling and Role Modeling Essay Example | Topics and Well Written Essays - 1000 words

Modeling and Role Modeling - Essay Example One of those foundation theories was Maslow's hierarchy of needs. Modeling is gaining an understanding of the clients world from the clients perspective. It assumes that all humans want to interact with others and quality holistic care is one of the goals. The propositions are the degree to which development tasks are resolved and is dependent on the degree to which human needs are satisfied and the ability to cope is directly related to the level of need satisfaction. It enhances the nurses ability to understand the worldview of adolescents and to use this gained understanding to design health education programs that address the adolescents development needs (Bray, 2005). The theory enables nursing to care for and nurture each client with an awareness of and respect for the individuals uniqueness and focus on that clients needs. Clients have the intelligence and ability to understand what has made them sick as well as what the plan is to make them well. Let's take the example of a young person who is admitted to the hospital with diabetes. She is readmitted regularly because she is out of control. When the nurse sits down to talk with her about her diabetes, she says she just wants to be like her friends and she does not want to say she can't have it when they go for a hamburger and fries. She just wants to feel normal. In this case, according to Erickson's model, the patient needs to be understood in her world, not in the world of the nurse (Arruda, 2005). When placing the nurse in that world she understands the pressure to be like her friends and try not to worry about her diabetes all the time. The nurse determines two interventions. She talks wit h the nutritionist to come up with a diet plan for the patient that would include the kinds of foods that a young person of that age likes to eat and she talks with the doctor about the possibility of an insulin pump. The nutritionist does come up with a plan that meets the young lady's needs and leaves some open space that she could fill with something like a shake if she went out with friends. An insulin pump is put in place (Sappington, 1996). The nurse has accomplished filling the patients needs while also assuring her understanding and buy in to meeting the needs of her disease This would of course be measured by the patient maintaining control and not being readmitted which she has not. There are five common goals of this theory and each of them was met in this case. Those goals are building trust, promoting positive orientation, promoting perceived control, promoting strengths and setting health directed mutual goals. Nursing retention is one of the greatest issues in healthcare today, with ageing nurses, and a shortage of new nurses, everyone wants to keep the ones they have. Modeling/ Role Modeling lends itself well to leadership decisions in healthcare. The client is the center of the theory. In this case, the client is the nurse. In understanding the nurses world we find what are the things that she needs most. We use Maslow's hierarchy of need and the five common goals of all interventions which again are trust, promoting positive orientation, promoting perceived control, promoting strength and setting directed mutual g
