What characterises the relationship between users and platforms? How are use and users configured by platform design, and in turn, how do users accept or reject such efforts? Using the live-streaming platform Twitch, this paper explores the user-platform relationship to answer these questions. Twitch is a highly popular live-streaming platform with an emphasis on gaming, whose rise to fame has been far from streamlined or expected. Based on qualitative analysis of design, discourse and user practices, the paper draws on script theory from science and technology studies and platform theory from Internet studies, to unpack the configuration of use and users. By tracing the development of the platform, we identify a pattern of frequent interaction between platform owners and users, and consequent course changes, which we label co-scription. Finally, we analyse the current Twitch script and propose five dimensions of co-scription that determine the user-platform relationship: 1) Sociality: community or individual use; 2) Audience: specific or general; 3) Moderation: strictly moderated or laissez-faire; 4) Content: user-generated or commercial; and 5) Scope: specialised or multi-feature.

Abstract The aim of this study is to point out the relationship between foreign language learning motivation and sign language use among hearing impaired Hungarians. In the article we concentrate on two main issues: first, to what extent hearing impaired people are motivated to learn foreign languages in a European context; second, to what extent sign language use in the classroom as well as outside school shapes their level of motivation. The participants in our research were 331 Deaf and hard of hearing people from all over Hungary. The instrument of data collection was a standardized questionnaire. Our results support the notion that sign language use helps foreign language learning. Based on the findings, we can conclude that there is indeed no justification for further neglecting the needs of Deaf and hard of hearing people as foreign language learners and that their claim for equal opportunities in language learning is substantiated.

This paper describes the relationship between the eigenfrequencies of CT scanned realistic human head model and the subjective detecting pitch, which is given by providing the bone-conducted ultrasound. Our goal is to develop the optimal bone-conducted ultrasonic hearing aid for profoundly hearing-impaired persons. An ascent of a speech intelligibility is the requirement of hearing aid. To improve it, the perception mechanism of the bone-conducted ultrasound must be clarified, but the conclusive agreement of it has not been reached yet, although many hypotheses were reported. The authors feel an interest in the detecting pitch of bone-conducted ultrasound with no frequency-dependence and predict that the cochleae are related to the perception mechanism for bone-conducted ultrasound, since it has been verified that the auditory cortex responds to bone-conducted ultrasound by MEG study. In this paper, waves propagating from the mastoid to both cochleae are numerically analyzed and the characteristics of transfer functions are estimated as a first step to clarifying the perception mechanism for detecting pitch of bone-conducted ultrasonic stimuli.

Critical bandwidth measurements and sensitivity prediction from the acoustic reflex (SPAR) test results were obtained on 20 normal-hearing and two groups of 10 hearing-impaired subjects each representing mild-to-moderate and severe hearing loss. Results of critical bandwidth measurements indicated that for center frequencies of 1000 and 2000 Hz the critical bandwidth was significantly greater for the hearing-impaired subjects. A statistical analysis of the difference in critical bandwidth between those predicted by the SPAR test to have a mild-to-moderate hearing loss and those subjects for whom the test predicted severe hearing loss indicated no differences in critical bandwidth at 2000 Hz. A significant difference was found at 1000 Hz but in the wrong direction. Analysis of the relationship between predicted slope of hearing loss and critical bandwidth also failed to show significance. Although the data for hearing-impaired subjects fail to support the rationale for the SPAR test, the results for the entire research sample offer substantial support. Further, the ability of the test to predict categorically degree of hearing loss was also strongly supported.

Cochlear implants (CI) enable hearing in individuals with sensorineural hearing loss, albeit with difficulties in speech perception and sound localization. In noisy environments, these difficulties are disproportionately greater for CI users than for children with no reported hearing loss. Parents of children with CIs are motivated to experience what CIs sound like, but options to do so are limited. This study proposes using virtual reality to simulate having CIs in a school setting with two contrasting settings: a noisy playground and a quiet classroom. To investigate differences between hearing conditions, an evaluation utilized a between-subjects design with 15 parents (10 female, 5 male; age M = 38.5, SD = 6.6) of children with CIs with no reported hearing loss. In the virtual environment, a word recognition and sound localization test using an open-set speech corpus compared differences between simulated unilateral CI, simulated bilateral CI, and normal hearing conditions in both settings. Results of both tests indicate that noise influences word recognition more than it influences sound localization, but ultimately affects both. Furthermore, bilateral CIs are equally to or significantly beneficial over having a simulated unilateral CI in both tests. A follow-up qualitative evaluation showed that the simulation enabled users to achieve a better understanding of what it means to be an hearing impaired child.
