The nature of age-related improvements in auditory sensitivity was explored by comparing behavioral and auditory brainstem response (ABR) thresholds in 3- and 6-month-old infants and in adults. Thresholds were estimated for tone pips at 1, 4, and 8 kHz, presented at a rate of 13.3/s. The time course of development of the two response measures was compared, and the correlation between thresholds...

prices of meat in the international and a nation's internal markets tend to be closely related to each other. this relation could be sometimes harmful and due to lagged responses, meat prices at the internal market would subsequently increase as input prices increase at either the internal or international market. price uncertainty and transmition are two important problems facing a nation...

This study investigates the relationships between company responses to social media complaints and consumers' repurchase intentions. An online survey collected data from 325 participants who complained on media. The relationship intention five dimensions of complaint handling (timeliness, redress, apology, credibility, attentiveness) as mediated by trust in were examined consumers’ propensity w...

Abstract We use a dynamic model of the U.S. apple industry separated into organic and conventional production to better measure impacts pest or disease outbreaks on producers consumers, along with an equilibrium displacement simulate welfare effects from various shocks compared baseline. Our results show that differ between methods. Growers’ consumers’ responses widely across industry. Farmers ...

Issue: Nearly 12.7 million individuals signed up for coverage in the Affordable Care Act's (ACA) health insurance marketplaces during the third open enrollment period, and by the end of March there were 11.1 million consumers with active coverage. States that operate their own marketplaces posted a year-to-year enrollment gain of 8.8 percent. To maintain membership and attract new consumers, th...

The Internet phone, which was recently introduced to the communication market, is characterized by its lower cost and increased compatibility. However, its popularity and diffusion is relatively low in the North American market compared with Asian or European markets. This study examines the adoption of Internet phone service in Korea to develop a better understanding of consumers’ acceptance o...

Automated Metering Infrastructure (AMI) is a energy technology that would allow consumers to exhibit price elasticity of demand under smart-grid environments. The market power of the generation and transmission companies can be mitigated when consumers respond to price signals. Such responses by consumers can also result in reductions in price spikes, consumer energy bills, and emissions of gre...

The effects of rise time and center frequency on the auditory brainstem response (ABR) elicited by high-frequency tone bursts were examined in six normal-hearing adults. Tone bursts with rise times of 0.1, 0.25, 0.5, and 1.0 msec, duration of 2 msec, and center frequencies of 8, 10, and 12 kHz were used in this study. The absolute latencies of waves I, III, and V were obtained in all subjects, ...

This study evaluated the effects of stimulus repetition rate, phase, and frequency on the auditory brainstem response (ABR) in normal-hearing neonates and adults. In both neonates and adults, the results clearly showed large ABR wave V latency differences between condensation and rarefaction for low-frequency stimuli. Phase dependent latency effects are believed to be a result of the phase-sens...

In order to elucidate why many elderly listeners have difficulty understanding speech under reverberation, we investigated the relationship between word intelligibility and auditory brainstem responses (ABRs) in 28 elderly listeners. We hypothesized that the elderly listeners with low word intelligibility scores under reverberation would show degraded subcortical encoding information of reverbe...
