Journal ArticleDOI
Discriminability of electrocutaneous stimuli after topical anesthesia: Detection-theory measurement of sensitivity to painful stimuli
TL;DR: In three experiments on the psychophysical measurement of pain, electrocutaneous currents were applied to the volar surface of the forearm and the slope of the cumulative sensitivity function increased with increasing elapsed time since the removal of the anesthetic.
Journal ArticleDOI
Infectious agents and gene expression differ between sockeye salmon (Oncorhynchus nerka) smolt age classes but do not predict migration survival
Christine F. Stevenson,Arthur L. Bass,Nathan B. Furey,Nathan B. Furey,Kristina M. Miller,Shaorong Li,Erin L. Rechisky,Aswea D. Porter,David Welch,Scott G. Hinch +9 more
TL;DR: In some salmonid populations, multiple smolt age classes co-emigrate owing to variation in the duration of freshwater residence, and it is assumed that smolts prolong freshwater residence to maxi-time.
Journal ArticleDOI
Slow recovery of heather (Calluna vulgaris L. (Hull)) in Scottish moorland after easing of heavy grazing pressure from red deer (Cervus elaphus L.)
TL;DR: In this article, the authors monitored heather attributes and deer distribution over ten years in Glen Lui and Glen Derry, two contrasting nearby areas of it 200 ha at Mar Lodge in the eastern Cairngorms.
Journal Article
Are hearing losses among young Maori different to those found in the young NZ European population
TL;DR: There are significant differences in the proportion of bilateral losses and in the rates and severity profile of hearing loss among young Maori when compared with their NZ European peers, which has implications for screening and other hearing services in NZ.
Journal ArticleDOI
Impact of cognition and noise reduction on speech perception in adults with unilateral cochlear implants.
Suzanne C. Purdy,David Welch,Ellen Giles,Catherine Morgan,Renique Tenhagen,Abin Kuruvilla-Mathew +5 more
TL;DR: Speech intelligibility significantly improved with the NR activated, but was independent of individual differences in cognitive abilities, and there was a trend for participants with good working memory to have better speech perception scores with NR activated during the effortful listening task (dual-task paradigm).
