The ancient world on the Victorian and Edwardian stage
\"The first study of the depictions of the Ancient World on the Victorian and Edwardian stage, this book analyzes plays set in and dramatising the histories of Greece, Rome, Egypt, Babylon and the Holy Land. In doing so, it seeks to locate theatre within the wider culture, tracing its links and interaction with other cultural forms\"--Provided by publisher.

A Social Feedback Loop for Speech Development and Its Reduction in Autism
We analyzed the microstructure of child-adult interaction during naturalistic, daylong, automatically labeled audio recordings (13,836 hr total) of children (8- to 48-month-olds) with and without autism. We found that an adult was more likely to respond when the child's vocalization was speech related rather than not speech related. In turn, a child's vocalization was more likely to be speech related if the child's previous speech-related vocalization had received an immediate adult response rather than no response. Taken together, these results are consistent with the idea that there is a social feedback loop between child and caregiver that promotes speech development. Although this feedback loop applies in both typical development and autism, children with autism produced proportionally fewer speech-related vocalizations, and the responses they received were less contingent on whether their vocalizations were speech related. We argue that such differences will diminish the strength of the social feedback loop and have cascading effects on speech development over time. Differences related to socioeconomic status are also reported.

Mapping the Early Language Environment Using All-Day Recordings and Automated Analysis
This research provided a first-generation standardization of automated language environment estimates, validated these estimates against standard language assessments, and extended on previous research reporting language behavior differences across socioeconomic groups.
Typically developing children between 2 to 48 months of age completed monthly, daylong recordings in their natural language environments over a span of approximately 6-38 months. The resulting data set contained 3,213 12-hr recordings automatically analyzed by using the Language Environment Analysis (LENA) System to generate estimates of (a) the number of adult words in the child's environment, (b) the amount of caregiver-child interaction, and (c) the frequency of child vocal output.
Child vocalization frequency and turn-taking increased with age, whereas adult word counts were age independent after early infancy. Child vocalization and conversational turn estimates predicted 7%-16% of the variance observed in child language assessment scores. Lower socioeconomic status (SES) children produced fewer vocalizations, engaged in fewer adult-child interactions, and were exposed to fewer daily adult words compared with their higher socioeconomic status peers, but within-group variability was high.
The results offer new insight into the landscape of the early language environment, with clinical implications for identification of children at-risk for impoverished language environments.
Journal Article
John Ruskin and the Victorian theatre
\"This the first sustained study of the interest of John Ruskin in the theatre of his time. It examines Ruskin's active engagement with and influence on the Victorian popular theatre. Ruskin was an enthusiastic and catholic theatre-goer, enjoying pantomime as much as Shakespeare. Through the lens of Ruskin's discussions of pantomime, melodrama, Shakespearean tragedy, and painting and the stage, Newey and Richards offer a new view of the late Victorian stage focusing on London's West End in its heyday\"-- Provided by publisher.

Automated Analysis of Child Phonetic Production Using Naturalistic Recordings
Purpose: Conventional resource-intensive methods for child phonetic development studies are often impractical for sampling and analyzing child vocalizations in sufficient quantity. The purpose of this study was to provide new information on early language development by an automated analysis of child phonetic production using naturalistic recordings. The new approach was evaluated relative to conventional manual transcription methods. Its effectiveness was demonstrated by a case study with 106 children with typical development (TD) ages 8-48 months, 71 children with autism spectrum disorder (ASD) ages 16-48 months, and 49 children with language delay (LD) not related to ASD ages 10-44 months. Method: A small digital recorder in the chest pocket of clothing captured full-day natural child vocalizations, which were automatically identified into consonant, vowel, nonspeech, and silence, producing the average count per utterance (ACPU) for consonant and vowel. Results: Clear child utterances were identified with above 72% accuracy. Correlations between machine-estimated and human-transcribed ACPUs were above 0.82. Children with TD produced significantly more consonants and vowels per utterance than did other children. Children with LD produced significantly more consonants but not vowels than did children with ASD. Conclusion: The authors provide new information on typical and atypical language development in children with TD, ASD, and LD using an automated computational approach.

Effects of cold on murine brain mitochondrial function
Therapeutic hypothermia is a strategy that reduces metabolic rate and brain damage during clinically-relevant hypoxic events. Mitochondrial respiration is compromised by hypoxia, with deleterious consequences for the mammalian brain; however, little is known about the effects of reduced temperature on mitochondrial metabolism. Therefore, we examined how mitochondrial function is impacted by temperature using high resolution respirometry to assess electron transport system (ETS) function in saponin-permeabilized mouse brain at 28 and 37°C. Respirometric analysis revealed that, at the colder temperature, ETS respiratory flux was ~ 40-75% lower relative to the physiological temperature in all respiratory states and for all fuel substrates tested. In whole brain tissue, the enzyme maximum respiratory rates for complexes I-V were similarly reduced by between 37-88%. Complexes II and V were particularly temperature-sensitive; a temperature-mediated decrease in complex II activity may support a switch to complex I mediated ATP-production, which is considerably more oxygen-efficient. Finally, the mitochondrial H+-gradient was more tightly coupled, indicating that mitochondrial respiration is more efficient at the colder temperature. Taken together, our results suggest that improvements in mitochondrial function with colder temperatures may contribute to energy conservation and enhance cellular viability in hypoxic brain.

Politics, performance and popular culture : theatre and society in nineteenth-century Britain
This collection brings together studies of popular performance and politics across the nineteenth century, offering a fresh perspective from an archivally grounded research base. It works with the concept that politics is performative and performance is political. The book is organised into three parts in dialogue regarding specific approaches to popular performance and politics. Part I offers a series of conceptual studies using popular culture as an analytical category for social and political history. Part II explores the ways that performance represents and constructs contemporary ideologies of race, nation and empire. Part III investigates the performance techniques of specific politicians - including Robert Peel, Keir Hardie and Henry Hyndman - and analyses the performative elements of collective movements.
