This article investigates the invisibility of Roma communities within Scottish census ethnic monitoring categories and broader empirical data. Consistent negative stereotyping as well as systematic oppression within social policy, dominant discourses, and data collection processes excludes Roma from participatorycitizenship. This article identifies precise forms of marginality and invisibility within official government data – permeated through social and education policy – that thereby limit the effective targeting of resources to marginalized communities. Specifically, the article argues that omitting Roma as an ethnic category from past data gathering processes limits understanding of the commonalities and differences within and amongScottish communities, rendering entire populations invisible within broader empirical data and therefore restricting both identification of needs and effective resource allocation. Thus, the article presents a timely argument for the inclusion of Roma as an ethnic category in the 2021 Scottish census, while addressingissues within the census approach to data collection – including the impending digitization of the process. Through discussing and advancing the case for the inclusion of Romani communities in the 2021 Scottish Census, the paper also seeks to establish the current social context by chronicling the history of Romanimigration and marginalization within Europe.

Cochlear implantation has successfully restored the perception of hearing for nearly 200 thousand profoundly deaf adults and children. More recently, implant candidature has expanded to include those with considerable natural hearing which, when preserved, provides an improved hearing experience in noisy environments. But more than half of these patients lose this natural hearing soon after implantation. To reduce this burden, biosensing technologies are emerging that provide feedback on the quality of surgery. Here we report clinical findings on a new intra-operative measurement of electrical impedance (4-point impedance) which, when elevated, is associated with high rates of post-operative hearing loss and vestibular dysfunction. In vivo and in vitro data presented suggest that elevated 4-point impedance is likely due to the presence of blood within the cochlea rather than its geometry. Four-point impedance is a new marker for the detection of cochlear injury causing bleeding, that may be incorporated into intraoperative monitoring protocols during CI surgery.

Objective: Lay the groundwork for using electrocochleography (ECochG) as a measure of cochlear health, by characterising typical patterns of the ECochG response observed across the electrode array in cochlear implant recipients with residual hearing. Methods: ECochG was measured immediately after electrode insertion in 45 cochlear implant recipients with residual hearing. The Cochlear Response Telemetry system was used to record ECochG across the electrode array, in response to 100- or 110-dB SPL pure tones at 0.5-kHz, presented at 14 per second and with alternating polarities. Hair cell activity, as the cochlear microphonic (CM), was estimated by taking the difference (DIF) of the two polarities. Neural activity, as the auditory nerve neurophonic (ANN), was estimated by taking the sum (SUM) of the two polarities. Prior work in humans and animal studies suggested that the expected ECochG pattern in response to a 0.5-kHz pure tone is an apical-peak in CM amplitude and latency. Results: The most prevalent pattern was a peak in the DIF amplitude near the most apical electrode, with a prolongation of latency towards the electrode tip; this was found in 21 / 39 individuals with successful ECochG recordings. The 21 apical-peak recipients had the best low-frequency hearing. A low amplitude, long-latency DIF response that remained relatively constant across the electrode array was found in 10 / 39 individuals, in a group with the poorest low- and high-frequency hearing. A third, previously undescribed, pattern occurred in 8 / 39 participants, with mid-electrode peaks in DIF amplitude. These recipients had the best high-frequency hearing and a progressive prolongation of DIF latency around the mid-electrode peaks consistent with the presence of discrete populations of hair cells. Conclusions: The presence of distinct patterns of the ECochG response with relationships to pre-operative hearing levels supports the notion that ECochG across the electrode array functions as a measure of cochlear health.
