Regional Specificity of Chlorhexidine Effects on Taste Perception

Abstract: Chlorhexidine (CHX) gluconate, a bitter bis-biguanide antiseptic, reduces the intensity of the salty taste of NaCl and bitter taste of quinine in humans. This study addresses regional specificity of CHX's effects on taste. Perceptual intensity and quality were measured for separate taste bud containing oral loci innervated either by afferent fibers of cranial nerve (CN) VII or CN IX. Measurements were obtained following three 1-min oral rinses with either 1.34 mM CHX or water, the control rinse. CHX rinse reduced the intensity of NaCl more at the tongue tip and palate than at posterior oral sites. Thus, fungiform and palatal salt-taste receptors may differ from salt-taste receptors of the foliate and circumvallate taste papillae. The intensity of quinine.HCl was reduced equally by CHX at all sites tested but was frequently tasteless on the less sensitive anterior sites, suggesting quinine receptor diversity. In rodents, a portion of NaCl-taste receptors in the receptive field of CN VII is sensitive to the epithelial Na+ channel blocker amiloride and a portion is amiloride insensitive; all CN IX receptors are amiloride insensitive. The current results are the first to suggest that there may also be distinct, regionally specific populations of NaCl-taste receptors in humans.

Critical Bands in the Perception of Speech Signals by Normal and Sensorineural Hearing Loss Listeners

Abstract: Existing auditory theory suggests a major role for critical bands. Scharf has defined the critical band empirically as “that bandwidth at which subjective responses rather abruptly change” (cf. Scharf, 1970, p. 159). In general, two stimuli separated in frequency by less than a critical bandwidth will interact in one of a number of ways, while two stimuli separated by more than a critical bandwidth will not. The critical band phenomenon has been observed in such perceptual phenomena as masking (Fletcher, 1940; Scharf, 1970), loudness (Zwicker, 1958), and musical consonance (Plomp, 1964).

Race, Ethnicity, Gender, and Violent Victimization:

Abstract: The victimization literature has clearly established race, ethnicity, and gender disparity in victimization risks whereas contemporary work has demonstrated that the intersection of these characteristics produces complex patterns in victimization risks. However, explanations for these differences within and across gender and race and ethnicity must continue to be explored and to that end the purpose of this research is to examine whether the well-established risk factors for victimization such as daily or routine activities and neighborhood conditions similarly influence risks for violent victimization among varying gender, racial, and ethnic groups. Using data from the National Crime Victimization Survey (NCVS) 12 Cities study, the authors find that risks do vary both across and within gender. While routine activities are significant predictors of females' risks, neighborhood conditions seem to be better indicators of males' risks. Also, routine activities and neighborhood conditions have disparate effec...

Television Attitudes and TV Types of African-Americans, Latinos, and Caucasians

Abstract: The growing influence of ethnic minorities and convergence of television with other communication technologies raises an important issue: are ethnic viewers different in their television attitudes and degree of technology acceptance and, if so, what are the implications for broadcasters and advertisers? This nationally representative study of 871 adult African-Americans, Latinos, and Caucasians revealed significant ethnic differences in the adoption of communication technologies, television programming preferences, and an established TV-type segmentation. Further analysis identified disparities in specific television and technology attitudes. Recommendations are offered for television programmers and advertisers to consider in targeting viewer segments based on their television and technology beliefs.
