System dynamics depends heavily upon quantitative data to generate feedback models. Qualitative data and their analysis also have a central role to play at all levels of the modeling process. Although the classic literature on system dynamics strongly supports this argument, the protocols to incorporate this information during the modeling process are not detailed by the most influential author...

UNLABELLED Objectives and importance of study: The purpose of this study was to illustrate how qualitative free-text comments, collected within the context of a health survey, represent a rich data source for understanding specific phenomena. STUDY TYPE Work conducted with data from the Australian Longitudinal Study on Women's Health (ALSWH) was used to demonstrate the breadth and depth of qu...

The problem of face alignment has been intensively studied in the past years. A large number of novel methods have been proposed and reported very good performance on benchmark dataset such as 300W. However, the differences in the experimental setting and evaluation metric, missing details in the description of the methods make it hard to reproduce the results reported and evaluate the relative...

In two prior papers in our series on qualitative research [Frankel & Devers (2000a, 2000b) Qualitative research: a consumer's guide, Education for Health, 13, 113-123; Frankel & Devers (2000) Study design in qualitative research-1: developing research questions and assessing research needs, Education for Health, 13, 251-261], we examine two critical issues in qualitative research design: sampli...

In this paper we propose a watermarking method in which Estimator based approach is used. Due to this approach simple spatial method could resist different noise attacks. For the evaluation of Imperceptibility & Robustness of the proposed method we have calculated different quality measure parameters. We have tested watermarked image against different noise attacks at different noise densities....
