Strategies for celebration: realising the ideal celebratory city in London and Paris, 1660-1715
Urban festival actively sought to transform the early modern city, creating an idealised
space that was deemed to be a more suitable site for celebration. This dissertation
shows how urban festival marked both the conjuncture and disjuncture between a
rhetorical ideal and the challenges inherent in its practical realisation in London and
Paris between 1660 and 1715.
Celebrations were located in the real early modern city‐ a space that posed all manner
of design problems for those responsible for designing, devising and choreographing
festival. While the ideal celebratory city did exist in the rhetoric that informed
preparations for events and their representation, festival also constituted a series of
performances in real space and time that were subject to uncontrollable factors, such as
poor weather, injury, uncooperative workforces and imperfect audience response. Only
those charged with commemorating festival had full control over the event, producing
the books, chronicles and illustrative material that are most often consulted as sources
by festival historians.
By means of a tripartite structure, this dissertation will interrogate how the deployment
of the spectacular aspired to create the ideal celebratory city at three key moments in
the narrative of every celebration. The first section focuses on the practical and
legislative preparations made before events. The second section considers the evidence
of what actually happened during the performance or realisation of the events. The
third, and final, part of the dissertation looks at the representation of celebrations in
printed textual descriptions and visual images. Starting from the evidence of objects,
including viewing platforms, fireworks, temporary architecture and bonfires, it will
suggest the extent to which the ideal was achieved and the ways in which it influenced
the practice of those involved in its production. Moreover, as a single event could be
informed by more than one version of the ideal celebratory city, evidence of
preparation, performance and representation will also demonstrate how far
celebrations were the product of contested ideals
Early Intervention Service Delivery via Telehealth During COVID-19: A Research-Practice Partnership
Coaching has been identified as a best practice for early intervention (EI) services provided through the Individuals with Disabilities Education Act (IDEA) Part C. The current study describes the establishment and progress of a research-relationship partnership to deliver coaching via telehealth during the COVID-19 pandemic. Community-based EI providers implemented 9-weeks of telehealth coaching and evaluated the extent to which child and caregiver outcomes differed between families that had previously received in-person services versus telehealth only. Four EI providers completed the intervention with n=17 families of children aged 6-34 months during the pandemic (April-August 2020). We used the Canadian Occupational Performance Measure (COPM) and Goal Attainment Scaling (GAS) to collect outcomes on caregiver identified goals; we used Wilcoxon Signed Rank Tests to examine pre- to post-intervention data. Results showed significant improvements in parent satisfaction, child performance, and goal attainment (all p<.01). Findings suggest that telehealth coaching procedures implemented by community-based EI providers resulted in improvements in caregiver identified goals for young children
A disease mutation reveals a role for Nav1.9 in acute itch
Itch (pruritis) and pain represent two distinct sensory modalities; yet both have evolved to alert us to potentially harmful external stimuli. Compared with pain, our understanding of itch is still nascent. Here, we report a new clinical case of debilitating itch and altered pain perception resulting from the heterozygous de novo p.L811P gain-of-function mutation in Na(V)1.9, a voltage-gated sodium (Na-V) channel subtype that relays sensory information from the periphery to the spine. To investigate the role of Na(V)1.9 in itch, we developed a mouse line in which the channel is N-terminally tagged with a fluorescent protein, thereby enabling the reliable identification and biophysical characterization of Na(V)1.9-expressing neurons. We also assessed Na(V)1.9 involvement in itch by using a newly created Na(V)1.9(-/-) and Na(V)1.9(L799P/WT) mouse model. We found that Na(V)1.9 is expressed in a subset of nonmyelinated, nonpeptidergic small-diameter dorsal root ganglia (DRGs). In WT DRGs, but not those of Na(V)1.9(-/-) mice, pruritogens altered action potential parameters and Na-V channel gating properties. Additionally, Na(V)1.9(-/-) mice exhibited a strong reduction in acute scratching behavior in response to pruritogens, whereas Na(V)1.9(L799P/WT) mice displayed increased spontaneous scratching. Altogether, our data suggest an important contribution of Na(V)1.9 to itch signaling
A Prospective Open Trial of Guanfacine in Children with Pervasive Developmental Disorders
Objective:
A common complaint for children with pervasive developmental disorder (PDD) is hyperactivity.
The purpose of this pilot study was to gather preliminary information on the efficacy of guanfacine in
children with PDD and hyperactivity.
Methods:
Children with PDD accompanied by hyperactivity entered the open-label trial if there was a recent
history of failed treatment with methylphenidate or the child did not improve on methylphenidate in a
multisite, placebo-controlled trial.
Results:
Children (23 boys and 2 girls) with a mean age of 9.03 (±3.14) years entered the open-label trial.
After 8 weeks of treatment, the parent-rated Hyperactivity subscale of the Aberrant Behavior Checklist
(ABC) went from a mean of 31.3 (±8.89) at baseline to 18.9 (±10.37) (effect size = 1.4; p < 0.001). The
teacher-rated Hyperactivity subscale decreased from a mean of 29.9 (±9.12) at baseline to 22.3 (±9.44)
(effect size = 0.83; p < 0.01). Twelve children (48%) were rated as Much Improved or Very Much
Improved on the Clinical Global Impressions– Improvement. Doses ranged from 1.0 to 3.0 mg/day in two
or three divided doses. Common adverse effects included irritability, sedation, sleep disturbance (insomnia
or midsleep awakening), and constipation. Irritability led to discontinuation in 3 subjects. There were no
significant changes in pulse, blood pressure, or electrocardiogram.
Conclusions:
Guanfacine may be useful for the treatment of hyperactivity in children with PDD. Placebocontrolled
studies are needed to guide clinical practice
An exploration of concomitant psychiatric disorders in children with autism spectrum disorder
Objective
We explored patterns of concomitant psychiatric disorders in a large sample of treatment-seeking children and adolescents with autism spectrum disorder (ASD).
Methods
Participants were 658 children with ASD (age 3–17 years; mean = 7.2 years) in one of six federally-funded multisite randomized clinical trials (RCT) between 1999 and 2014. All children were referred for hyperactivity or irritability. Study designs varied, but all used the Child and Adolescent Symptom Inventory or Early Childhood Inventory to assess Attention Deficit Hyperactivity Disorder (ADHD), Oppositional-Defiant Disorder (ODD), Conduct Disorder (CD), Anxiety Disorders, and Mood Disorders. In addition, several measures in common were used to assess demographic and clinical characteristics.
Results
Of the 658 children, 73% were Caucasian and 59% had an IQ >70. The rates of concomitant disorders across studies were: ADHD 81%, ODD 46%, CD 12%, any anxiety disorder 42%, and any mood disorder 8%. Two or more psychiatric disorders were identified in 66% of the sample. Of those who met criteria for ADHD, 50% also met criteria for ODD and 46% for any anxiety disorder. Associations between types of concomitant disorders and a number of demographic and clinical characteristics are presented.
Conclusion
In this well-characterized sample of treatment-seeking children with ASD, rates of concomitant psychiatric disorders were high and the presence of two or more co-occurring disorders was common. Findings highlight the importance of improving diagnostic practice in ASD and understanding possible mechanisms of comorbidity
Autism spectrum disorder in fragile X syndrome: Communication, social interaction, and specific behaviors
The present study extends our previous work on social behavior impairment in young males with fragile X syndrome (FraX). Specifically, we evaluated whether the autistic phenomenon in FraX is expressed as a range of behavioral impairments as in idiopathic autism (Aut). We also examined whether there are behaviors, identified as items of the Autism Diagnostic Interview-Revised (ADI-R), that in FraX predispose to or differentiate subjects with autism spectrum disorder (ASD) diagnosis. Finally, regression models were utilized to test the relative contribution of reduced communication and socialization skills to ADI-R scores and diagnoses. A cohort of 56 boys (3-8 years) with FraX was examined in terms of scores on measures of cognition (IQ was a co-variate in most analyses.), autistic behavior, problem/aberrant behavior, adaptive behavior, and language development. We found that, indeed, in terms of problem behavior and adaptive skills, there is a range of severity from FraX þ Aut to FraX þ PDD (Pervasive Developmental Disorder) to FraX þ none. ADI-R items representing ''Play'' types of interaction appear to be ''susceptibility'' factors since they were abnormal across the FraX cohort. Integrated regression models demonstrated that items reflecting complex social interaction differentiated the FraX þ ASD (Aut þ PDD) subgroup from the rest of the FraX cohort, while abnormalities in basic verbal and non-verbal communication distinguished the most severely affected boys with FraX þ Aut from the milder FraX þ PDD cohort. Models incorporating language, adaptive communication, and adaptive socialization skills revealed that socialization was not only the main influence on scores but also a predictor of ASD diagnosis. Altogether, our findings demonstrate that the diagnosis of ASD in FraX reflects, to a large extent, an impairment in social interaction that is expressed with variable severity in young males with FraX. ß 2004 Wiley-Liss, Inc
