This dissertation examines the role of the fundamental economic variables (price levels, interest rates, and income levels) in the determination of foreign exchange rates during the period 1973-1978. Purchasing power parity, the International Fisher Effect, and the relationship of exchange rates with income levels through the marginal propensity to import were integrated, as suggested by the literature, and a fairly reasonable specification of a model for exchange rate determination was measured. The results of speculation tests indicate destabilizing results for some currencies and stabilizing results for the others; the coefficient of expectation tests, however, lend support to the destabilizing hypothesis. The conclusion of the research, therefore, is that the exchange rates of the major industrial countries which are of prime importance to the international financier and investor, and to the student of international finance and trade, are primarily determined, not by the fundamental economic variables, but by speculative forces which are believed to be of a destabilizing nature.

The purpose of this study was basically twofold: 1) to develop an evaluative instrument to measure interpersonal communicative competence, and 2) to determine its relationship to three other supervisory variables—demographic characteristics, self-actualization, and leader behavior. Hypotheses testing, via the Pearson correlation coefficient, indicated the following relationships between interpersonal communicative competence (as measured by the IICC) and supervisory demographics, self-actualization (as measured by the POI), and leader behavior (as measured by the SBDQ): 1) The age of the supervisor was negatively related to the IICC at the .001 level of statistical significance. 2) Years of formal education was positively related to the IICC at the .001 level. 3) The sex of the supervisor (females scoring higher) was related to the IICC at the .01 level. 4) No significant relationship existed between years of supervisory experience and the IICC. 5) Six scales of the POI (I, Ex, Fr, S, A, C) were related to the IICC at the .001 level of statistical significance, one scale (Sy) at the .01 level and two scales (Tc, Sa) at the .05 level. Three scales (SAV, Sr, Nc) were not significantly related to the IICC. 6) No significant relationship existed between the IICC and the two …
