Looking through a new lens, exploring the interdependent relationship between interprofessional education and collaborative practice with Polarity Thinking.

The context of interprofessional education (IPE) and collaborative practice (IPCP) has led to calls for greater alignment, coordination, and coalitions among education and healthcare delivery systems. One method to evaluate and improve these coalitions is the Polarity Thinking framework. Polarities, such as IPE and IPCP, can represent interdependent pairs of different but complementary values or perspectives.

Effect of rate-alteration on speech perception in noise in older adults with normal hearing and hearing impairment.

Purpose: The purpose of this study was to evaluate the effect of using slow and fast speaking rates in competing noise on older adults with normal hearing (NH) and those with hearing impairment (HI).

Method: Thirty-four older adults (56-85 years) were grouped based on hearing ability-NH (N = 15) and HI (N = 19). Rate-altered Quick Speech-in-Noise Test (QuickSIN; Etymotic Research, 2001) stimuli were presented at 3 speech rates (slow, average, and fast), and the signal-to-noise ratio (SNR) loss was calculated for each.

Effects of reverberation on acceptable noise level measurements in younger and older adults.

Acceptable noise level (ANL) test materials were digitally modified to create five reverberant conditions by applying different values of reverberation time (RT) to a non-reverberant condition (RT = 0, 0.4, 0.7, 1.

Safety and immunogenicity study of Multiclade HIV-1 adenoviral vector vaccine alone or as boost following a multiclade HIV-1 DNA vaccine in Africa.

Background: We conducted a double-blind, randomized, placebo-controlled Phase I study of a recombinant replication-defective adenovirus type 5 (rAd5) vector expressing HIV-1 Gag and Pol from subtype B and Env from subtypes A, B and C, given alone or as boost following a DNA plasmid vaccine expressing the same HIV-1 proteins plus Nef, in 114 healthy HIV-uninfected African adults.

Methodology/principal Findings: Volunteers were randomized to 4 groups receiving the rAd5 vaccine intramuscularly at dosage levels of 1×10(10) or 1×10(11) particle units (PU) either alone or as boost following 3 injections of the DNA vaccine given at 4 mg/dose intramuscularly by needle-free injection using Biojector® 2000. Safety and immunogenicity were evaluated for 12 months.

Effects of speech rate, background noise, and simulated hearing loss on speech rate judgment and speech intelligibility in young listeners.

Purpose: To study the effect of noise on speech rate judgment and signal-to-noise ratio threshold (SNR50) at different speech rates (slow, preferred, and fast).

Research Design: Speech rate judgment and SNR50 tasks were completed in a normal-hearing condition and a simulated hearing-loss condition.

Study Sample: Twenty-four female and six male young, normal-hearing participants.

Effects of reverberation and filtering on speech rate judgment.

This study investigated the effects of listening condition on speech rate judgment. Four listening conditions, in which a single sentence was presented at 21 speech rates ranging from 90 WPM to 250 WPM, were incorporated. These conditions included non-degraded, reverberation, band-pass filtered, and low-pass filtered conditions, each of which was selected to simulate listening conditions one might encounter in daily life.

Safety and immunogenicity of a polyvalent peptide C4-V3 HIV vaccine in conjunction with IL-12.

We examined the safety and immunogenicity of a human leukocyte antigen-based HIV envelope polyvalent synthetic peptide vaccine, C4-V3, alone and in combination with subcutaneous IL-12 in nine HIV-infected patients. Lymphocyte proliferative responses increased threefold or more to all four peptides at two consecutive post-immunization timepoints for four individuals. Three responders had received IL-12, suggesting a possible adjuvant effect of Il-12.

Older adult performance on an altered version of the SSI test.

The Synthetic Sentence Identification (SSI) test has been used extensively in investigations of reduced speech understanding skills in older adults. In this study the SSI test was altered by adding noise to the competing message and by administering practice lists and equivalent test lists, as well as versions of the test that have 4- and 12-s interstimulus intervals (ISIs), along with the standard 8-s ISI. The purpose was to determine the effect of these alterations on performance in a group of older adults with average pure-tone average 2 values less than 33 dB HL.
