Methodological Variables For Eliciting Maximum Phonational Frequency Range In Adults, K. Lenee Moseley

Masters Theses

The current study employed an experimental research design to compare the effect of elicitation tasks (glissando versus discrete-steps) and the integration of visual feedback (auditory-only model versus visual feedback with an auditory model) on obtaining an individual's maximum phonational frequency range (MFPR). Participants included forty normal speaking males and females. A one-way ANOVA indicated the glissando elicitation task yielded a significantly higher MPFR than the discrete-steps elicitation task. [F (1,159) = 34.39; p < .01]. A one-way ANOVA approached but did not reach statistical significance [F (1,159) = 3.104, p = .08] for the difference between the auditory-only model and the auditory model with visual feedback. However, the frequency means depicted a larger MPFR when visual feedback was included within each of the elicitation tasks.

The Role Of Real Exchange Rate On Output And Trade Balance: Evidence From Ethiopia, Daniel Getachew Ayele

Masters Theses

This paper examines the role of exchange rates in determining the trade balance and output behavior for Ethiopia. Conventional wisdom says that a real devaluation improves the trade balance and has an expansionary impact on output. Empirically, the evidence for both developed and developing countries has been inconsistent in either rejecting or supporting this hypothesis. This paper attempts to find evidence for these conditions. It uses a regression model formulation which includes income and money so that the monetary and absorption approaches to the balance of payments are also examined. The econometric procedure used is the Engle-Granger two-step method to …
