Several studies have considered the ability of devout Christians to accept homosexual persons while rejecting homosexual behavior. Batson, Floyd, Meyer, and Winner (1999) found that intrinsic Christians were not able to make that distinction. Bassett et al. (2000) found that intrinsic Christians were able to distinguish between the value of homosexual persons and behavior. Both studies used financial help as the measure of acceptance. This study replicated the Batson et al. methodology with some modifications. The basic methodology involves students working at a time-limited task, which might financially benefit another “student.” What is varied in the procedure is the description of the other “student” (regarding sexual orientation and what the person intends to do with the money). Results from the study suggested that intrinsic Christians were able to “love the sinner but hate the sin.”

This paper presents the development of a wave-based room-prediction model for predicting steady-state sound fields in empty rooms with specularly reflecting, multilayer surfaces. A triangular beam-tracing model with phase, and a transfer-matrix approach to model the surfaces, were involved. Room surfaces were modeled as multilayers of fluid, solid, or porous materials. Biot theory was used in the transfer-matrix formulation of the porous layer. The new model consisted of the transfer-matrix model integrated into the beam-tracing algorithm. The transfer-matrix model was validated by comparing predictions with those by theory, and with experiment. The test surfaces were a glass plate, double drywall panels, double steel panels, a carpeted floor, and a suspended-acoustical ceiling. The beam-tracing model was validated in the cases of three idealized room configurations—a small office, a corridor, and a small industrial workroom—with simple boundary conditions. The number of beams, the reflection order, and the frequency resolution required to obtain accurate results were investigated. Beam-tracing predictions were compared with those by a method-of-images model with phase. The model will be used to study sound fields in rooms with local- or extended-reaction multilayer surfaces.
