Practices of negotiating responsibility for troubles in interaction involving people with hearing impairment
For people with hearing impairment (HI), the need to repair hearing-related troubles within conversation is a constant concern that can significantly impact their everyday life and social relationships. This chapter examines repair sequences initiated by people with HI within two corpora, one comprising video-recorded interaction in audiology appointments, the other, audio-recorded interaction between adults with HI and a chosen familiar conversation partner. In particular, the analysis explores the person with HI’s use of meta-comments (“I can’t hear you”, “you’re mumbling”) in the repair sequences to negotiate responsibility for the hearing trouble between the speakers. The findings highlight that the person with HI has an expectation that their communication partners will adapt their talk for the HI recipient to aid the progress of the conversation
The distribution of interplanetary dust between 0.96 and 1.04 au as inferred from impacts on the STEREO spacecraft observed by the heliospheric imagers
The distribution of dust in the ecliptic plane between 0.96 and 1.04 AU has
been inferred from impacts on the two STEREO spacecraft through observation of
secondary particle trails and unexpected off-points in the Heliospheric Imager
(HI) cameras. This study made use of analysis carried out by members of a
distributed web-based project, Solar Stormwatch. A comparison between
observations of the brightest particle trails and a survey of fainter trails
shows consistent distributions. While there is no obvious correlation between
this distribution and the occurrence of individual meteor streams at Earth,
there are some broad longitudinal features in these distributions that are also
observed in sources of the sporadic meteor population. The asymmetry in the
number of trails seen by each spacecraft and the fact that there are many more
unexpected off-points in the HI-B than in HI-A, indicates that the majority of
impacts are coming from the apex direction. For impacts causing off-points in
the HI-B camera these dust particles are estimated to have masses in excess of
10-17 kg with radii exceeding 0.1 {\mu}m. For off-points observed in the HI-A
images, which can only have been caused by particles travelling from the
anti-apex direction, the distribution is consistent with that of secondary
'storm' trails observed by HI-B, providing evidence that these trails also
result from impacts with primary particles from an anti-apex source. It is
apparent that the differential mass index of particles from the apex direction
is consistently above 2. This indicates that the majority of the mass is within
the smaller particles of this population. In contrast, the differential mass
index of particles from the anti-apex direction (causing off-points in HI-A) is
consistently below 2, indicating that the majority of the mass is to be found
in larger particles of this distribution.Comment: Accepted by MNRA
