The Aurora Borealis Essay -- physics space

The Aurora Borealis is made when storms on the the sun form solar winds, or large streams of charged particles streaming toward the earth.These streams could have upward of ten million megawatts of electrical power. That is enough power to light up Los Angeles. It generally takes about three days for these streams of particles to reach the earth's upper atmosphere, or ionosphere. When these charged particles hit the earth's atmosphere, they excite the atoms contained in the atmosphere. These excited atoms have a higher energy state that usual and so want to get back to a more normal energy state. The excited atoms give off excess energy in the form of heat, or the case of the Aurora Borealis, light. The trillions of excited atoms give off enough light so that we can see the light from where we live on the ground, 43-200 miles above us. The Aurora Borealis is most often seen in a striking green color, but it also occasionally shows off its many colors ranging from red to pink, blue to purple, dark to light. The reason that the aurora is seen in so many colors is that our atmosphere is made up of many different compounds like Oxygen and Nitrogen. When the charged particles that come from the sun hit the atoms and molecules of the Earth's atmosphere, they excite those atoms, giving off light. Different atoms give off different colors of the spectrum when they are excited. A familiar example is the Neon lights that we see on many business signs in our modern world. The Neon lights contain the gas Neon. These lights have electricity run through them to excite the Neon gas. When the Neon is excited, it gives off a brilliant red-orange color. The Neon lights are the same idea as the aurora, only on a lot smaller scale. Different ga... ... as a story from Scotland, tell of battles in the sky with showers of red blood. A story from the Northern Hebrides attributes the aurora to supernatural beings called Blue Men. During an active display of the aurora the Blue Men are called the Merry Dancers also known as na fir chlis (Gaelic for quick, nimble men). When the aurora moves rapidly, there is believed to be a battle going on between clans. The red light was attributed the the blood spilled during these battles. In Norse mythology, there is reference to Bifrost, or a bridge to the sky built by the Gods. This bridges was said to be on fire to keep the Giants out. In Medieval art, the aurora was dipicted as candles in the sky. In Greenland, it was said that the aurora represented the dead playing with the head of a walrus. No matter what the tale, they are all interesting and are worthy of reading.

E Commerce, An Aspect Of Information Communications...

Small farms have an important part in the rapid expansion of the U.S. agricultural sector (USDA-NASS, 2015). Ninety-two percent of all farms in the United States are classified as small with small farms being defined as those with annual gross revenues of $250,000 or less (USDA-NASS, 2015). A way to increase the competitiveness of small farmers is to enhance their management practices and to expand their capacities through the use of tools such as electronic commerce (e-commerce) (Briggeman Whitacre, 2010; Roe et al., 2014). E-commerce, an aspect of information communications technology (ICT), is defined as the buying, selling, and marketing of goods and services online (Hua et al., 2015).

Theories support economically non-rational reasons that small American farm farmers might adopt e-commerce; diffusion of innovations theory (Rogers, 2010) supports that farmers could adopt e-commerce out of a desire to imitate their peers, a form of social behaviorism detected in a previous study of small farm farmers (Palis, 2006). It could also be the case that the environment promotes e-commerce adoption at all costs (Hua et al., 2015). While these kinds of theories have been generally successful in explaining the economically rational as well as non-rational contexts of e-commerce technology adoption, they have not been applied to small American farm farmers. As a consequence, neither e-commerce vendors nor e-commerce policy-makers understand what is driving the adoption or non-ado ption of e-commerce in small farm management. It is especially of interest that among the 20% of e-commerce adoption among small farm farmers that the adoption is not driven by economically rational motivations (Bojeec Latruffe, 2013). Such theories have also not been applied to understanding why small farm farmers do not adopt e-commerce. There is sufficient E Commerce, An Aspect Of Information Communications...

E-commerce has advantages for small farm farmers seeking to expand opportunities (Alston Pardey, 2014). However, the way in which e-commerce is strategically managed is not fully understood. Miles and Snow’s (2006) strategic typology offers a means of more systematically understanding, how and why small farm farmers make particular e-commerce management decisions. The typology is a concept used in strategic management to assist organizations with making strategic management decisions, it helps management to understand the type of organizational structure to adopt, and lastly it assists with determining what functional strategies areShow MoreRelatedE Commerce, An Aspect Of Information Communications Technology1335 Words   |  6 Pagescapacities through the use of tools such as electronic commerce (e-commerce) (Briggeman Whitacre, 2010; Roe et al., 2014).
