Identifying Validity in Qualitative Research: A Literature Review

This paper explores multiple articles relating to qualitative research. Qualitative research has seen several transformation that aim to support contributions for this research development. As research, using a qualitative methodology rises to prevalence, this paper explores industry and academia use of this methodology. The paper review research based in the field of healthcare and social work. After analysis, the review of literature shows that a majority qualitative research are within the field healthcare (Johnson, 1999). The research conducted embraces a diverse collection of approaches to inquiry intended to generate knowledge actually grounded in human experience. The literature review also addressed “rigor” as a standard for valid research, and the impending presumption for flexibility as called for by pundits against qualitative research paradigm. It was argued that this call for rigidity could threaten the innovativeness and hence the meaning and quality of a qualitative research. The author then review and describe the concept of validity to a qualitative research paradigm and how it is applied as discussed by Creswell (2013). Creswell discusses five approach, narrative, Phenomenology, grounded theory, ethnography and case study, which we will review through the paper

Influence of disk leakage path on labyrinth seal inlet swirl ratio

The results of numerous investigators have shown the importance of labyrinth seal inlet swirl on the calculated dynamic stiffness of labyrinth seals. These results have not included any calculation of inlet leakage swirl as a function of geometry and sealing conditions of the given seal. This paper outlines a method of calculating the inlet swirl at a given seal by introducing a radial chamber to predict the gas swirl as it goes from the stage tip down to the seal location. For a centrifugal compressor, this amounts to including the flow path from the impeller discharge, down the back of the disk or front of the cover, then into the shaft seal or eye packing, respectively. The solution includes the friction factors of both the disk and stationary wall with account for mass flow rate and calculation of radial pressure gradients by a free vortex solution. The results of various configurations are discussed and comparisons made to other published results of disk swirl

An Economical Semi-Analytical Orbit Theory for Retarded Satellite Motion About an Oblate Planet

Brouwer and Brouwer-Lyddanes' use of the Von Zeipel-Delaunay method is employed to develop an efficient analytical orbit theory suitable for microcomputers. A succinctly simple pseudo-phenomenologically conceptualized algorithm is introduced which accurately and economically synthesizes modeling of drag effects. The method epitomizes and manifests effortless efficient computer mechanization. Simulated trajectory data is employed to illustrate the theory's ability to accurately accommodate oblateness and drag effects for microcomputer ground based or onboard predicted orbital representation. Real tracking data is used to demonstrate that the theory's orbit determination and orbit prediction capabilities are favorably adaptable to and are comparable with results obtained utilizing complex definitive Cowell method solutions on satellites experiencing significant drag effects
