The accessible museum: towards an understanding of international museum audio description practices

Introduction: Audio description (AD) in museums is crucial for making them accessible for people with visual impairments. Nevertheless, there are limited museum-specific AD guidelines currently available. This research examines current varied international practitioner perspectives on museum AD, focusing on imagery, meaning, emotion and degrees of objectivity, and the regional differences (Europe, US) in AD traditions, in order to better understand how museum AD can be used to enhance access. Methods: Forty-two museum describers from 12 countries responded to a questionnaire requiring fixed-choice and free-text responses about the purpose and construction of museum AD. Results: Inference tests showed that European describers agreed more strongly than US describers that AD should ‘explore meaning’ (U = 91.00, N1 = 24, N2 = 14, p = 0.03), and ‘create an emotional experience’ (U = 89.50, N1 = 24, N2 = 14, p = 0.03), rating the use of cognitive prompts as more important (U = 85.50, N1 = 21, N2 = 14, p = 0.04). Qualitative data enriched this understanding by exploring participant responses on the themes of mental imagery, objectivity and interpretation and cognitive prompts. This highlighted broader agreement between regions on mental imagery, but more acceptance of interpretation in AD from the European respondents. Discussion: US and European describers’ opinions differ regarding the purpose of AD: whether it is about conveying visual information or whether broader interpretations should be incorporated into descriptions for audiences with visual impairments. Implications for Practitioners: These findings indicate that further discussion is needed regarding the purpose of museum AD, and in particular the way in which objectivity is contextualised. They raise questions about AD providing visual information, and/or seeking to address a wider museum experience, including the stimulation of curiosity or emotion

‘I felt I was right there with them’: the impact of sound-enriched audio description on experiencing and remembering artworks, for blind and sighted museum audiences

This study explored the impact of sound-enriched audio descriptions (AD) on the experience and memorability of a digitally presented photography exhibition. Forty blind and partially blind (BPB) and forty sighted participants were presented with eight photographs from the Museum of London’s archive. Four photos were presented with a standard audio descriptive guide (ADG) and four with a sound-enriched audio descriptive guide (EDG). Experience and memorability were assessed directly after the presentation, and approximately 4 weeks later. Results demonstrated that sighted people remembered more photos than BPB people did with ADG. However, when photos were presented with EDG, the BPB and sighted groups remembered equal number of photos and equal numbers of details. EDG was also enjoyed and preferred by both BPB and sighted participants. Findings suggest that EDGs could be used within mainstream museum offerings as inclusive audio interpretation, thus enhancing access and enjoyment for many visitors and facilitating shared experiences

Remembering Cultural Experiences: lifespan distributions, richness and content of autobiographical memories of museum visits

Little is known about our autobiographical memories for cultural events. This represents an opportunity for cultural institutions such as museums, as examination of visitor memories is one way in which they can seek to understand the long-term impact they may have on their visitors. This research applied a coding model developed from autobiographical memory theory to analysis of participants’ memories for museum visits, considering the distribution of memories across the life span, types of memories and content. Differences between visitor groups (age, visit frequency) were also considered. Findings showed a strong recency effect in the life-span distribution, suggesting the importance of social sharing in memories of cultural experience. Analysis of content showed a hierarchy of information that was present in museum memories. Knowledge acquired during the event of the visit was important, as was contextualising information whereby visitors situated the memory within their autobiographical knowledge and chronology. Emotions and thoughts were also salient. Visitor differences had minimal impact on content, with the exception of some effects that were consistent with the literature on memory and ageing. This research develops understanding of autobiographical memories for cultural experiences and provides insight to museums, with practical implications in terms of understanding visitors’ experiences

Epigenetic Interactions and the Structure of Phenotypic Variation in the Cranium

Understanding the developmental and genetic basis for evolutionarily significant morphological variation in complex phenotypes such as themammalian skull is a challenge because of the sheer complexity of the factors involved. We hypothesize that even in this complex system, the expression of phenotypic variation is structured by the interaction of a few key developmental processes. To test this hypothesis, we created a highly variable sample of crania using four mouse mutants and their wild-type controls from similar genetic backgrounds with developmental perturbations to particular cranial regions. Using geometricmorphometricmethods we compared patterns of size, shape, and integration in the sample within and between the basicranium, neurocranium, and face. The results highlight regular and predictable patterns of covariation among regions of the skull that presumably reflect the epigenetic influences of the genetic perturbations in the sample. Covariation between relative widths of adjoining regions is the most dominant factor, but there are other significant axes of covariation such as the relationship between neurocranial size and basicranial flexion. Although there are other sources of variation related to developmental perturbations not analyzed in this study, the patterns of covariation created by the epigenetic interactions evident in this sample may underlie larger scale evolutionary patterns in mammalian craniofacial form.Anthropolog

Complex differences in infection rates between ethnic groups in Scotland: a retrospective, national census-linked cohort study of 1.65 million cases

Background Ethnicity can influence susceptibility to infection, as COVID-19 has shown. Few countries have systematically investigated ethnic variations in infection. Methods We linked the Scotland 2001 Census, including ethnic group, to national databases of hospitalizations/deaths and serological diagnoses of bloodborne viruses for 2001–2013. We calculated age-adjusted rate ratios (RRs) in 12 ethnic groups for all infections combined, 15 infection categories, and human immunodeficiency virus (HIV), hepatitis B (HBV) and hepatitis C (HCV) viruses. Results We analysed over 1.65 million infection-related hospitalisations/deaths. Compared with White Scottish, RRs for all infections combined were 0.8 or lower for Other White British, Other White and Chinese males and females, and 1.2–1.4 for Pakistani and African males and females. Adjustment for socioeconomic status or birthplace had little effect. RRs for specific infection categories followed similar patterns with striking exceptions. For HIV, RRs were 136 in African females and 14 in males; for HBV, 125 in Chinese females and 59 in males, 55 in African females and 24 in males; and for HCV, 2.3–3.1 in Pakistanis and Africans. Conclusions Ethnic differences were found in overall rates and many infection categories, suggesting multiple causative pathways. We recommend census linkage as a powerful method for studying the disproportionate impact of COVID-19

J-Integral Calculation by Finite Element Processing of Measured Full-Field Surface Displacements

© 2017 The Author(s)A novel method has been developed based on the conjoint use of digital image correlation to measure full field displacements and finite element simulations to extract the strain energy release rate of surface cracks. In this approach, a finite element model with imported full-field displacements measured by DIC is solved and the J-integral is calculated, without knowledge of the specimen geometry and applied loads. This can be done even in a specimen that develops crack tip plasticity, if the elastic and yield behaviour of the material are known. The application of the method is demonstrated in an analysis of a fatigue crack, introduced to an aluminium alloy compact tension specimen (Al 2024, T351 heat condition)

Variation in monitoring and treatment policies for intracranial hypertension in traumatic brain injury: A survey in 66 neurotrauma centers participating in the CENTER-TBI

Background: No definitive evidence exists on how intracranial hypertension should be treated in patients with traumatic brain injury (TBI). It is therefore likely that centers and practitioners individually balance potential benefits and risks of different intracranial pressure (ICP) management strategies, resulting in practice variation. The aim of this study was to examine variation in monitoring and treatment policies for intracranial hypertension in patients with TBI. Methods: A 29-item survey on ICP monitoring and treatment was developed based on literature and expert opinion, and pilot-tested in 16 centers. The questionnaire was sent to 68 neurotrauma centers participating in the Collaborative European Neurotrauma Effectiveness Research (CENTER-TBI) study. Results: The survey was completed by 66 centers (97% response rate). Centers were mainly academic hospitals (n = 60, 91%) and designated level I trauma centers (n = 44, 67%). The Brain Trauma Foundation guidelines were used in 49 (74%) centers. Approximately ninety percent of the participants (n = 58) indicated placing an ICP monitor in patients with severe TBI and computed tomography abnormalities. There was no consensus on other indications or on peri-insertion precautions. We found wide variation in the use of first- and second-tier treatments for elevated ICP. Approximately half of the centers were classified as having a relatively aggressive approach to ICP monitoring and treatment (n = 32, 48%), whereas the others were considered more conservative (n = 34, 52%). Conclusions: Substantial variation was found regarding monitoring and treatment policies in patients with traumatic brain injury and intracranial hypertension. The results of this survey indicate a lack of consensus between European neurotrauma centers and provide an opportunity and necessity for comparative effectiveness research
