Research Articles - Essay Example Qualitative evaluation based on ethnographic method at two suburban high schools. The setting for the study is two suburban school (Gance-Cleveland 2004 p.380). Children are persuaded to share the details of the problems in the family in a trusting and supportive environment and by creating a less stigmatizing and more positive environment for the participants. The research was approved by IRB (Institutional review board) and prior permission was obtained from cofacilitators, administrators and students for each interview. The anonymity of the participant was safeguarded in theoretical sampling in focus groups through by using code numbers in the data (Gance-Cleveland 2004 p.382). Patients were reviewed from an academic health center. Inclusion criteria are used with a face to face interview prior to the hospitalization and the measurement of pain through various methods preoperatively and post operatively (Ridge & Goodson 2000 p.71). The sample size constituted various numbers of participants for each study. The size of the sample seems to be adequate considering the age and probability of the hip replacement surgery. The study was conducted in an academic health centre ((Ridge & Goodson 2000 p.72). Five data collection instruments were used. They are Functional Status Index, Arthritis Impact Measurement Scale, Health Assessment Questionnaire, Sickness Impact Profile and Index of Well Being. The data was collected once before the surgery and twice after the surgery (Ridge & Goodson 2000 p.72) The ethical rights of the patients was safeguarded during the research since it is evident that patients were not forced to participate and even participants who dropped during the course of the research were not included in the final analysis ((Ridge & Goodson 2000 p.74). The research was conducted in a written format through the selection of statements in outcome measurement instrument that reduces the changes of bias in the data. The sampling

Alfred Wegener ideas about Continental drift Research Paper

Alfred Wegener ideas about Continental drift - Research Paper Example Wegner’s ideas on plate motion were later on developed by different researchers. One of them is Kiyoo Wadati, who suggested that plate motion has resulted in often earthquakes in Japan, and those earthquakes are connected to the continental drift. He compared data from different earthquakes and identified a specific earthquake zone in the oceanic trench (Garrison, p. 70). Hugo Benioff pointed out that Kiyoo Wadati’s findings were related to the â€Å"subduction of the seafloor†("The Giants of Science"). Harry Hess was able to move beyond Wegener’s ideas and develop them in a different direction. He discovered how the seafloor spreading operates and what role magma plays in it by filling in the deep oceanic trenches ("Harry Hammond Hess: Spreading the Seafloor") Ronald Dietz arrived at the same conclusion, however the Hess owns the idea that continents move together with an attached oceanic basin on the same crust (Garrison, p.70). Tuzo Wilson analy zed Hawaiian Islands and their relation to tectonic plates. He concluded that these island were created as a result of plate’s movement northwest over the â€Å"hotspots† ("J. Tuzo Wilson: Discovering Transforms and Hotspots").
