Observation Journal#3 - Essay Example Avery approached a structure meant for them to play inside and climb, that was in the playground and tried to climb in it with difficulties. ‘Teacher! Teacher! he shouted looking at the teacher who was with other children inside the structure. The teacher then pulled Avery up and finally he was in the structure. Avery started jumping on the play structure as he falls down. He was jumping as he is shouting and laughing at the same time. I have observed that Avery does not take much time on a particular place for long, but he keeps running up and down touching one thing and another within a short time. Avery saw another child leave the play structure and go to the slide that was just beside the structure. Avery then went out of the play structure and ran very fast towards the slide. He suddenly stopped near the climbing staircases of the slide. He was keenly looking at the staircases and other children as they climbed one by one to the slide. He then stepped on the first staircas e with his right foot. Seeing that it was stable, Avery began climbing up the slide faster as there was another child coming after him. When Avery reached the top, and now it was time for him to slide down, he got afraid and refused to slide down. He blocked the way for the other children who were enjoying themselves in the slide. Avery then moved on one side of the slide, paving way for the other children to pass and slide themselves down. Avery sat up there looking at his fellow children slide with a lot if ease. He was cheering them up one by one as they were going down the slide. Avery suddenly lost the grip of the walls of the slide as he was clapping his hands to cheer the other children. Avery began sliding down unknowingly. ‘Huuuu! Huuuuu! he shouted as he was going down the slide. When he was down the slide, Avery began running away from the slide area, towards his teacher. ‘Teacher, poop, Avery told his teacher. ‘Ooh, you want to poop? ‘Yes,

Review Article - Essay Example The researchers subjected the cadavers’ spines to 20Â º of flexion and 15Â º of extension, then measured intradiscal pressures, along with segmental motion, at the intact C4-C5 and C6-C7 vertebrae of their specimens respectively. Subsequently, they measured these variables on the C5-C6 vertebrae following anterior cervical plating. By performing a paired measures t-test on their measurements of changes in intradiscal pressure and segmental motion, the authors arrived at their results. The research findings demonstrated that intradiscal pressures (the dependent variable) increased considerably during the flexion (the independent variable) imposed upon them. Pressures at the C4-C5 vertebrae increased by roughly 73.2% during the course of this flexion, and at the C4-C5, an increase in pressure of approximately 45.3% was observed. Although intradiscal pressures at adjacent levels increased during pressure, this effect failed to reach significance. Both during extension and flexion, the researchers’ measurements of segmental motion during flexion increased at these adjacent levels. Based on these results, the authors cite substantial intensification of intradiscal pressure and segmental motion at levels adjacent to fusion as primary causes of early disc degeneration and pathology. In part, these measured effects account for one mechanism of early disc degeneration at levels adjacent to cervical spine fusion, which is in line with the author’s hypothesis. Issues relating to a criticism of Eck et al. (2002) fall generally between two categories: (a) potential confounding variables in the design of the experiment, and (b) methodological limitations that may prevent more accurate results. One potential confound in the experiment is the possibility of inconsistency between the cadaver specimens. In the Materials and Methods section, no mention is made of how the cervical spines of these
