qualitative and quantitative research methods are different in some aspects but they complement each other in other aspects, as well. following widespread criticism of qualitative and quantitative research methods, there is increasing trend in using mixed research methods in social sciences in general and political science in particular. most advocates of pluralism attempted to fill the gap bet...

Although pyelonephritis is a common disease, it escapes clinical detection in an undesirably high proportion of patients. The present unsatisfactory diagnostic position would be much improved by widespread screening of patients by simple yet reasonably accurate methods. Bacterial counts by the pour-plate technique and estimates of the white cell excretion per hour or day, while undoubtedly of d...

Quantitative magnetic resonance imaging (qMRI) aims to quantify tissue parameters by eliminating instrumental bias. We describe qMRI theory, simulations, and software designed to estimate proton density (PD), the apparent local concentration of water protons in the living human brain. First, we show that, in the absence of noise, multichannel coil data contain enough information to separate PD ...

The analysis of networks of ecological trophic transfers is a useful complement to simulation modeling in the quest for understanding whole-ecosystem dynamics. Trophic networks can be studied in quantitative and systematic fashion at several levels. Indirect relationships between any two individual taxa in an ecosystem, which often differ in either nature or magnitude from their direct influenc...
