Clinical Significance Of Response Shift In A Spine Interventional Clinical Trial, 2015 Walden University
Clinical Significance Of Response Shift In A Spine Interventional Clinical Trial, Robin Carlson
Walden Dissertations and Doctoral Studies
The effectiveness of treatments for degenerative spine conditions, where the primary symptom is back pain, is typically determined using patient-reported quality of life (QoL) measures. However, patients may adjust their internal standards when scoring QoL based on factors other than their health. This response shift phenomenon could confound the interpretation of study data and impact effectiveness conclusions. In the current study, response shift was examined using structural equation modeling (SEM) and previously collected clinical trial data comparing 2 minimally invasive medical devices in lumbar spinal stenosis patients through 1 year postintervention. In subject QoL results, reprioritization shift between 3 months …

It is clear that Biomass can make a substantial contribution to supply future energy demand in a sustainable way. However, the supply of sustainable energy is one of the main challenges that mankind will face over …
A Critical Analysis Of Integrated Coastal And Ocean Management In Bangladesh With Lessons From Global Practices, 2015 World Maritime University
A Critical Analysis Of Integrated Coastal And Ocean Management In Bangladesh With Lessons From Global Practices, Syed Mamtajul Islam
World Maritime University Dissertations
The coast of Bangladesh is highly dynamic, unique and diverse, the south-western part of which hosts the world’s largest single mangrove forest; the south-central part receives the world’s second largest river system (Ganges-Brahmaputra-Meghna system), contributing to form the world’s largest delta in Bangladesh; and the south-eastern part provides room for major industrial and economic activities such as ports and shipping, ship recycling (2nd in global ranking), ship building, fisheries and tourism (Beaches in Cox’s Bazar – the world’s longest). The earlier land-side coastal management initiatives, which totally ignore ocean issues, have failed to bring a remarkable outcome mainly due to …
