This contribution offers an overview of the 'third research paradigm', its historical roots and its relevance for health informatics. Using illustrative studies, we explore the concepts of triangulation and integration of quantitative and qualitative data and refute common philosophical objections to mixing different types of knowledge. We consider how the mixed method paradigm relates to two p...

in natural gas treatment, the removal of co2 and h2s in acid gases is a critical concern. there are various purification technologies that can be used for the removal of acid gas impurities. absorption of acid gas into amines is one preferred method in gas industries. in the past, single amines was used, but recently in order to improve absorption performance, mixed amines with different solubi...

vendor selection is dominantly considered to be a multi attribute decision making (madm) problem, since the decision maker needs to evaluate suppliers simultaneously in different and even contrastive evaluation criteria. one shortcoming of madm methods is that they only compare alternatives with each other, and there is no comparison with the requirements of the buying company. a very efficient...

Most assessments, like the math subtest of the SAT or the GRE, are unidimensional, in that they treat all questions on the test as sampling a single underlying “skill”. Can we predict state tests scores better if we tag the questions with fine-grained models the skills needed? Psychometricians don’t do this presumably because they don’t get better fitting model, for a variety of reasons. We are...
