Plate Tectonics - Research Paper Example is composed of plates that are in motion with respect to one another and that the majority of the deformation associated with this motion is concentrated along the plate boundaries (Fichter, 2000). Back in 1968, Morgain provided an explanation that plate tectonics constitutes "a kinematic model which describes the relative motion between the rigid plates that make up the outer shell of Earth" (Morgan, 73). Practically, the relative motion between the plates is accommodated by seafloor spreading and the creation of new plates at ocean ridges, subduction of the surface plate at ocean trenches, and strike-slip motion at transform faults which allows plate motion without creating or removing surface plates. The motion of the continents is facilitated by the movement of the lithospheric plates, and this transport of the continents is referred to as continental drift. Plate tectonics on Earth has been determined to have been in operation for at least two billion years and may well have bee n in operation much earlier (Cawood et al., 5). theory, with its collisional orogenies and other episodic events, was in some wise dependent or interdependent upon "new catastrophism." That is, though plate tectonics largely relies upon uniformitarianism as a basis of understanding plate motion and subsurface processes, it nevertheless proffers catastrophes and other episodic events that proceed at rates greater than those existing between events. Examples include mountain building, various volcanic processes, and sea-level change resulting from mid-oceanic ridge formation. Between 1908 and 1912, Frank B. Taylor, American geologist, and Alfred Wegener, a German meteorologist and astronomer, working independently, proposed the idea that the continents were not fixed on the surface of the Earth but were slowly moving about. One point of Taylor's argument was that continental drift was needed to account for the folding and compression of the Alps and the Himalayas. Wegener was more influenced by the rough parallelism between the opp osing shores of the Atlantic and by evidence of climatic changes through geological time. Later Wegener proposed that all the Earth's land area was at one time "united in a single primordial supercontinent, which he named Pangaea, from Greek meaning 'all land" (Hallam, 93). The continents had shifted, becoming increasingly separated through millions of years. He believed that the continent were made up of light-weight granitic rocks, which like giant ships driven through the heavier basaltic seas (Hallam, 95). Wegener looked upon the continents as flexible masses instead of rigid plates. Some of his work was in error, for example, the amount of time involved in continental drift. Alfred Wegener established a tradition in geology and geophysics, according to which further development of theory of plate tectonics has been formed within the scientific debate over the ideas of stationary continents and continental drift. For instance, Hallam commented that "interpretation of how science

EMR Implementation and Patient Flow Case Study Example | Topics and Well Written Essays - 500 words

EMR Implementation and Patient Flow - Case Study Example Another benefit of the EHR is that all medical information can be created and supervised by authorized users. That`s option allowed providers to share the health information with the other health care providers to improve the quality and productivity of the diagnostic and treatment processes. But, the implementation process of the EHRs is not that quickly, easily and cheap because it requires some period of time for health providers education and adaptation of the health care system to the new model of the patient`s health information. The most difficult environment for the EHRs implementation is an emergence department as there are a lot of barriers such as crowding, limited staffing and increased amount of interruptions. The main question is: â€Å"Whether the overflow clinic model could be quickly adapted to offload the emergency department for the implementation of the EHR?† The other important information that have to be quantitatively confirmed is the effects of the EHR implementation on time to medical provider, total patient`s length of stay (LOS), provider efficiency during and after the implementation of the EHR. In addition, the quiet necessary question is: â€Å"How much time and training required for implementation and adoption of the software?† The data were gathered from the Cincinnati Children’s Hospital Medical Center emergence department during the 2 years of the EHR implementation. During this period the H1N1 flu pandemic occurred that lead to increased number of the patients. The results showed that the total length of stay during EHR implementation increased compared to the overall LOS before implementation. It takes 6 months post- implementation to gain improved and stable LOS. I suggest that received results show that the process of the EHR is quite slow because of the different reasons and barriers existed in the emergence departments. For example, health care providers require more time to learn how to use EHR as they have busy
