Who Should be Interviewed? A Response from Cluster Analysis

Objective: This article presents an application of cluster analysis for social sciences researches especially those studies that have an interview as part of their data collection. This application is more suitable for sequential mixed method researchers who use quantitative data to frame subsequent qualitative subsamples for conducting interviews.  Methods: In more detail, the algorithm (i....

Comments on Nonfinite Adverbial Patterns in English Prose Fiction: A Simple Model for Analysis and Use

This study aims to present an accessible model of some frequent nonfinite adverbial types occurring in English prose fiction. As its main syntactic argument, it recognizes that these adverbials are mostly elliptical in that there are some dependent-clause markers one can assume to be implicit when supplying those elements back into the clause complex. Some comments are provided at the end on th...

Synthetics and Theoretical Seismology

range and the location of artificial reflectors or intermediate values at these points. A similar fictitious sources inherent in discrete wave economy can be obtained using the itrerative reflection and transmission coefficient relations number techniques. The number and spacing of wave numbers in wave number integration schemes are of Kennett. Kamel and Felsen (1981) presented a hybrid determi...

Synthetics and Simulants

identified the gem as glass, but the nature of the strange veins containing tiny trapped gas bubbles remained a mystery. Fourier-transform infrared (FTIR) spectroscopy was performed next, but no polymers were detected. The RI was recorded as 1.52, and we concluded that this gem consisted of a solid piece of green lead glass. Viewed with the microscope, an experienced eye might sense that there ...
