Impacts of Global Climate Change on Temperature and Precipitation Patte

Impacts of Global Climate Change on Temperature and Precipitation Patterns in the Midwest and the Consequences for Soils Introduction During the last century, human activities in agriculture, industry and technology have brought about a change in the chemical composition of the atmosphere. This change so far has not had a noticeable or discernible effect on world climate, but if these same activities continue, global climate change will become irreversible. The major contributing factor is the increase in the amount of carbon dioxide and other gasses in the atmosphere. These gasses are being cited as the cause for a "greenhouse effect" where they trap the heat of the sun and cause global climate change, specifically a warming trend on the surface of the Earth. Many different scenarios for the possibilities and extent of global climate change have been proposed, and many global climate models have been created to look at the possibilities. While there are a wealth of differing opinions, there are also some consistencies in the predictions. Among other things, climate change is expected to cause increases in average global temperatures and changes in worldwide precipitation patterns. Even though these broad consequences are agreed upon, the affects which these changes will have on the climates and ecosystems around the world is still a matter of uncertainty. However, there is some consensus for the localized effects of global change in different climatic zones of the world. In the subboreal climate of the Midwestern region of North America, it is generally agreed that the temperature will increase an average of one to five degrees over the next ten to one hundred years (Varallyay, 1990). Also, it is expected that overall ... ...e Scenarios for Soil Erosion Potential in the USA" Land Degredation and Rehabilitation 4: 61-72 Ritchie, J.C. 1986 "Climate change and vegetation response", Vegetation 67: 67-74 B.G.

Perception Essay Essay

When we look at something, are we all seeing the same thing? Perception is the ability to see, hear, or become aware of something through the senses. It is the way in which something is regarded and understood. Metaphysicians, Logicians, Political and Social philosophers have thought about perception since the beginning of history. We all perceive; our sensual organs discern information the way they are designed to however, do we see differently because we all interpret what we see differently? One of the major senses is sight. This sense allows us to see by simply reflecting light onto one of our organs. The complex part however is the decoding of the information that is reflected. Our minds interpret the light that is reflected and turn it into information for us to sense our environment. It can be argued that the processed information is not always true. One example of this idea of flawed information would be the Rubin’s Vase form, which was developed by Edgar Rubin, a Danish psychologist. The visual effect generally presents the viewer with two shape interpretations, each of which is consistent with the image. The viewer is meant to see two images; one being two humans facing each other and the other is a vase. This form is an illusion and is created by the mind. The fact that there are two images seen to us does not mean that one of them has to be wrong. There is no wrong or right, it is just how our brains interpret the information. It can be considered that these interpretations are affected by our lifestyles and societies. Interpretation of the same image also changes from person to person. If looked on a bigger scale, these changes are affected from differences in cultures and paradigms. Color is also a major variable in testing perception after illusions. Do we see colors differently? One of BBC’s most fascinating shows: â€Å"Do You See What I See† explores this question. In the English language, there are distinct words to describe specific colors. â€Å"Green† and â€Å"Blue† describe specifically the wavelengths received by our eyes, color is after all just waves. 2 circles made up of 5 green squares on the left side, and 4 green squares and 1 blue square on the right. When the same image was shown to villagers from northern Namibia, they couldn’t pick out the blue square on the right however, picked out the  slightly different green colored square on the left. Any kind of conclusion can be made from this research. For example, because of less vegetation in Namibia, the habitants have a more fragile sense of color when it comes to green. They can differentiate very easily. Further research shows that there are many other factors affecting color perception including peoples’ moods, memories and feelings. Everybody sees the same wavelength but every individual sees a different color. Emotions also play a vital part in creating a perception. When we are filled with our emotions, we tend to be out of control of things. We always think that what we believe is always right no matter what the circumstances are. One great example of such behavior is the emotion of love. When we are deeply in love with a particular person, our understanding of happiness changes into only being oriented around them. The same thing goes for if we dislike somebody. Everything they do annoys us. This is generally referred to as â€Å"Emotions taking over†. The senses are accompanied by other senses to further prove that something is correct. A person sees a yellow pencil inside a glass of water. The pencil is curved and it is therefore perceived by that person that it is that way. However when the person removes the pencil from the water by touching it, it is understood that the pencil was not curved after all. This is a common allegory used by philosophers to explain how senses are used together to perceive. The person touches the pencil in order to feel its texture and therefore disprove his interpretation through sight. Other senses such as hearing, smelling and tasting are also used in accompaniment to seeing. It can be reasoned that people use different sense with sight and end up seeing something else in accordance to someone else. In conclusion every person’s skill to see is the same. Every person has the ability to receive light and process it into information however; the decoding of this information is different in each and every human being. Illusions show us something that is not there or alters the image we see. Our minds process it in the most useful way for us to perceive. As other sight related perceptions, it can be debated that every person sees  illusions differently according to what they have learned over their life. This is closely related to the way our societies are built. Our minds and our perception are affected by our teachings from our societies. What we see and what we perceive is rendered in order of usefulness to our environment and us. Emotion is also majorly related to perception. It can be debated whether our perception affects our emotions or whether our emotions affect our perceptions, however it obvious that our emotions play a vital part in what we see.

Pursuing An Advanced Degree For Nursing - 1187 Words

My desire to pursue an advanced degree in nursing relates not only to one event that has occurred in my life but a succession of personal and professional circumstances. My mother was a Registered Nurse (RN) and worked full time for 35 years in a hospital. She was regularly consulted by family members, friends and neighbors for medical advice and I admired the way she was able to help others recover their health and improve their quality of life. Helping one of my uncles during his recovery from an amputation of both legs was also a turning point. My uncle froze his feet, and the gangrene from his frostbite became septic. An emergency surgery was performed to amputate not only his feet, but both legs just below the knee. Short after the†¦show more content†¦He was doing well, but lost his battle when he contracted a fungal infection and died of respiratory failure, even though the leukemia was in remission. During this sad episode, I further realized the crucial role of nurs es in providing care and supporting patients in such situations. In my professional life as a nursing assistant, I have the opportunity to work with many nurses and witness how nurses work alongside their patients observing, assessing and caring for their needs. I find this dedication to the people in need very admirable and this creates in me a desire to perform professionally at this level. In five years time, I would like to be acting as a Registered Nurse, utilizing the nursing skills and knowledge acquired during my post-baccalaureate program to improve the lives of the patients I will be caring for. As I sustain my career in the healthcare system, I will be constantly improving and building upon my skills, education and professional development. I originate from a long line of nurses and other healthcare professionals, and this makes me believe that my personal background will help me achieve my goal of becoming a nurse. Caring for people seems to be embedded in my personality. Just being able to initiate a smile on the faces of those I help, makes it all worthwhile. I am the kind of person who likes to ensure that everyone is happy and who is very open to people
