AW participated in the development of the research design, reviewed existing literature, and revised the manuscript substantially.
The symptom lists were devised based on existing literature, and revised following piloting of the questionnaire with a local Coeliac UK members group.
Emergent codes were added, and existing codes revised where necessary.
Recognizing the global relevance of the issue of endocrine disruption, in addition to the US-EPA activities, the OECD initiated a high-priority activity in 1998 to revise existing, and to develop new test guidelines for the screening and testing of potential endocrine disrupting chemicals.
They reviewed the literature and revised the existing guideline for pain management according to the current standard [8].
Existing items were categorized, reviewed, and revised, creating a large pool of items that were then validated with item-response theory to allow for computer adapted testing, making the PROMIS instruments an important contribution to clinical and research practice while minimizing respondent burden.
Scores derived from four existing scoring systems (Revised Trauma Score, Triage Revised Trauma Score, Trauma and Injury Severity Score and MGAP score) were calibrated using logistic regression models that fit in the derivation set.
Also among the changes for 2011 are new test dummies and revised injury criteria for existing front- and side-impact tests, which are otherwise unchanged.
Codes were then derived, existing codes were revised if new codes emerged (further coding and recoding), and further analysis was conducted to develop themes that could authentically and accurately represent the topic being studied [ 16].
Older works, though, are fair game, but shouldn't artistic principles and respect for the creator's intent factor in? To explore the parameters for adapting and revising existing works I talked to Stephen Sondheim, an outspoken critic of "The Gershwins' Porgy and Bess".
