Ninety-two candidates in varying stages of a K-6 teacher education program responded to the Reading Teachers' Sense of Efficacy Scale. Data analysis using ANOVA and Fisher's LSD post-hoc comparisons revealed student teachers (Tier 4) had higher overall perceived reading teacher efficacy (M = 131.96, SD = 12.45) than those in the first semester methodology courses (Tier 2) (M = 117.68, SD = 16.43), p = .001 and the second semester of methodology courses (Tier 3) (M = 121.52, SD = 13.61), p = .005. Additionally, Tier 4 preservice teachers had significantly higher perceived reading teacher efficacy than those in both Tier 2 and Tier 3 for 9 individual scale items (p< .05). The perceived increased efficacy is largely credited to positive mastery experiences during the final internship semester.

To better understand how hearing is affected by structural properties, the current research investigated the impact of football helmets for hearing. Speech signals were broadcast at three angles of incidence (0°, 45°, or 90°) to an artificial dummyhead recording device wearing a football helmet (experimental condition) or without the helmet (control condition) to make binaural recordings using condenser microphones positioned at the location of the tympanic membrane. Acoustic analyses revealed that the helmet caused frequency-specific changes to an auditory signal, including both positive and negative interference that varied in relationship to the angle of incidence. Behavioral studies showed that while; in general, the football helmet made hearing speech more difficult, the magnitude of the decrement was a function of the amount of spectral change induced in the speech signal. Results are discussed in terms of the implications of an ecological approach to hearing and the design of helmets.

Here we present a new 33-item measure of GN called the Grandiose Narcissism Scale (GNS) that exhibits a reproducible seven-factor structure that maps on to Raskin and Terry's (1988) seven factor model. GNS subscales exhibit high reliability, with several being substantially more reliable than their NPI counterparts. As a full-scale, the GNS correlates with other variables in a way that is consistent with the theoretical portrait of GN. Additionally, two of the GNS subscales (entitlement, exploitativeness) are shown to uniquely predict independent measures of entitlement and exploitativeness, suggesting good subscale validity. Cumulatively, the GNS represents a viable complement or alternative to the NPI.
