Consumer Ethnocentrism: A Comparison of Arab and Western Audiences

The subject of consumer ethnocentrism is discussed in the context of advertising country-of-origin effects. The literature and suggestions concerning the phenomenon in the Middle East are brought up and a study using U.S. and Egyptian samples is described. The findings show some evidence of consumer ethnocentrism in both countries, though statistical significance is only achieved with U.S. data, generally consistent with prior writing and research focused on developed versus developing countries. Special attention is given to the construct of worldliness and though not statistically significant, results suggest it may be a factor deserving additional study

The effects of winglets on low aspect ratio wings at supersonic Mach numbers

A computational study was conducted on two wings, of aspect ratios 1.244 and 1.865, each having 65 degree leading edge sweep angles, to determine the effects of nonplanar winglets at supersonic Mach numbers. A Mach number of 1.62 was selected as the design value. The winglets studied were parametrically varied in alignment, length, sweep, camber, thickness, and dihedral angle to determine which geometry had the best predicted performance. For the computational analysis, an available Euler marching technique was used. The results indicated that the possibility existed for wing-winglet geometries to equal the performance of wing-alone bodies in supersonic flows with both bodies having the same semispan. The first wing with winglet used NACA 1402 airfoils for the base wing and was shown to have lift-to-pressure drag ratios within 0.136 percent to 0.360 percent of the NACA 1402 wing-alone. The other base wing was a natural flow wing which was previously designed specifically for a Mach number of 1.62. The results obtained showed that the natural wing-alone had a slightly higher lift-to-pressure drag than the natural wing with winglets
