For more than a quarter of a century, Sean O’Casey enjoyed living in what he called the ‘delightful county’ of Devon. O’Casey remained newsworthy in Ireland until his death, but he lived in relative anonymity in this English seaside area, and today the county does little to remember the writer. This chapter examines the way that O’Casey interacted with the local area of Devon, and the chapter also illustrates how his writing was shaped by the personal events that happened in this geographical location, such as the death of his son Niall from cancer in 1956, his interaction with Devon neighbours, and the contact he enjoyed with visitors who travelled to meet him, such as the Irish playwright Denis Johnston.
Inadequate recruitment and retention impede clinical trial goals. Emerging decentralized clinical trials (DCTs) leveraging digital health technologies (DHTs) for remote recruitment and data collection aim to address barriers to participation in traditional trials. The ACTIV-6 trial is a DCT using DHTs, but participants’ experiences of such trials remain largely unknown. This study explored participants’ perspectives of the ACTIV-6 DCT that tested outpatient COVID-19 therapeutics.
Methods:
Participants in the ACTIV-6 study were recruited via email to share their day-to-day trial experiences during 1-hour virtual focus groups. Two human factors researchers guided group discussions through a semi-structured script that probed expectations and perceptions of study activities. Qualitative data analysis was conducted using a grounded theory approach with open coding to identify key themes.
Results:
Twenty-eight ACTIV-6 study participants aged 30+ years completed a virtual focus group including 1–4 participants each. Analysis yielded three major themes: perceptions of the DCT experience, study activity engagement, and trust. Participants perceived the use of remote DCT procedures supported by DHTs as an acceptable and efficient method of organizing and tracking study activities, communicating with study personnel, and managing study medications at home. Use of social media was effective in supporting geographically dispersed participant recruitment but also raised issues with trust and study legitimacy.
Conclusions:
While participants in this qualitative study viewed the DCT-with-DHT approach as reasonably efficient and engaging, they also identified challenges to address. Understanding facilitators and barriers to DCT participation and DHT interaction can help improve future research design.
We present a re-discovery of G278.94+1.35a as possibly one of the largest known Galactic supernova remnants (SNRs) – that we name Diprotodon. While previously established as a Galactic SNR, Diprotodon is visible in our new Evolutionary Map of the Universe (EMU) and GaLactic and Extragalactic All-sky MWA (GLEAM) radio continuum images at an angular size of $3{{{{.\!^\circ}}}}33\times3{{{{.\!^\circ}}}}23$, much larger than previously measured. At the previously suggested distance of 2.7 kpc, this implies a diameter of 157$\times$152 pc. This size would qualify Diprotodon as the largest known SNR and pushes our estimates of SNR sizes to the upper limits. We investigate the environment in which the SNR is located and examine various scenarios that might explain such a large and relatively bright SNR appearance. We find that Diprotodon is most likely at a much closer distance of $\sim$1 kpc, implying its diameter is 58$\times$56 pc and it is in the radiative evolutionary phase. We also present a new Fermi-LAT data analysis that confirms the angular extent of the SNR in gamma rays. The origin of the high-energy emission remains somewhat puzzling, and the scenarios we explore reveal new puzzles, given this unexpected and unique observation of a seemingly evolved SNR having a hard GeV spectrum with no breaks. We explore both leptonic and hadronic scenarios, as well as the possibility that the high-energy emission arises from the leftover particle population of a historic pulsar wind nebula.
In our Introduction we briefy discuss Collingwood’s life and philosophical career, as well as mentioning his work in other fields such as history and archaeology. We argue for the continued relevance of Collingwood’s thought for both twenty-first-century academic philosophy and for some of the central concerns of contemporary life beyond academia, such as scientism, the idolatry of technology, and the current political climate. The second part of the Introduction gives an overview of the fourteen chapters in the volume.
An indisputably prominent figure in twentieth-century philosophy, R. G. Collingwood often remains elusive even to those who admire his achievements. This volume of new essays aims to reintroduce Collingwood to twenty-first-century philosophical readers and to show why, and how, his achievements matter. Each essay offers an original contribution to the understanding of some aspect of Collingwood's thought, including new interpretations of several of his central ideas, re-examinations of his place in twentieth-century philosophy, and an extended consideration of a previously undiscussed manuscript. The essays span the wide range of Collingwood's interests, including metaphysics, epistemology, logic, philosophy of mind, aesthetics, and political philosophy, as well as Roman British history and the history of art. Emphasis is placed on Collingwood's connections to traditions with which his name is not typically linked, including pragmatism, analytic philosophy, and phenomenology. This rich volume will stimulate further examination of Collingwood and his legacy.
Nostalgia is a longing for the past that emerges at a time of unprecedented and uncomfortable change. Nostalgia haunts modernisms as a continual reminder of the importance of reflecting on the past when pursuing the new, which is why Stan Smith has argued that ‘modernism is a retrospective artefact, a movement constituted backwards’. Accordingly, modernist nostalgia is an act of remembrance that denies forgetting, reconfiguring the past in the present to reflect on the pleasures and pains of modernity. Modernist nostalgia provides unique perspectives on the contemporaneity of the past when anticipating the future and, as Tammy Clewell points out, ‘nostalgia offers a crucial vantage point from which to assess the embeddedness of modernism in myriad political contestations of the period’. My concern in this chapter is to examine the role and function of modernist nostalgia in twenty-first-century Irish dance to demonstrate how modernism is embedded in contemporary cultural conditions in Ireland. Claire Warden points out that modernisms are ‘fruitfully disquieted by the embodied, ephemeral art of dance’ and to demonstrate this I will focus on MÁM, a contemporary Irish dance performance that premiered at the O’Reilly Theatre in Dublin, Ireland in September 2019. However, while my focus is on MÁM, my larger consideration in this chapter is to theorise the contemporary performance of modernist nostalgia in general, thereby considering the role and function of modernist nostalgia on an individual and collective level in contemporary Irish culture.
Tradition, Nostalgia and Mimesis: Teaċ Daṁsa's MÁM
MÁM was the result of eight weeks of improvisation in a community hall in the townland of Feothanach in the Corac Dhuibhne gaeltacht (district/districts in which the Irish language is the primary language) in west County Kerry, Ireland. Here, Michael Keegan-Dolan, in collaboration with his company Teaċ Daṁsa, traditional Irish musician Cormac Begley, and s t a r g a z e (a European orchestral collective of classical contemporary musicians), created MÁM, a non-narrative Irish dance performance that reflected on the role and function of nostalgia for traditional Irishness in contemporary Irish culture. Traditional Irish culture was deeply embedded and embodied in MÁM.
Many clinical trials leverage real-world data. Typically, these data are manually abstracted from electronic health records (EHRs) and entered into electronic case report forms (CRFs), a time and labor-intensive process that is also error-prone and may miss information. Automated transfer of data from EHRs to eCRFs has the potential to reduce data abstraction and entry burden as well as improve data quality and safety.
Methods:
We conducted a test of automated EHR-to-CRF data transfer for 40 participants in a clinical trial of hospitalized COVID-19 patients. We determined which coordinator-entered data could be automated from the EHR (coverage), and the frequency with which the values from the automated EHR feed and values entered by study personnel for the actual study matched exactly (concordance).
Results:
The automated EHR feed populated 10,081/11,952 (84%) coordinator-completed values. For fields where both the automation and study personnel provided data, the values matched exactly 89% of the time. Highest concordance was for daily lab results (94%), which also required the most personnel resources (30 minutes per participant). In a detailed analysis of 196 instances where personnel and automation entered values differed, both a study coordinator and a data analyst agreed that 152 (78%) instances were a result of data entry error.
Conclusions:
An automated EHR feed has the potential to significantly decrease study personnel effort while improving the accuracy of CRF data.
To describe the cumulative seroprevalence of severe acute respiratory coronavirus virus 2 (SARS-CoV-2) antibodies during the coronavirus disease 2019 (COVID-19) pandemic among employees of a large pediatric healthcare system.
Design, setting, and participants:
Prospective observational cohort study open to adult employees at the Children’s Hospital of Philadelphia, conducted April 20–December 17, 2020.
Methods:
Employees were recruited starting with high-risk exposure groups, utilizing e-mails, flyers, and announcements at virtual town hall meetings. At baseline, 1 month, 2 months, and 6 months, participants reported occupational and community exposures and gave a blood sample for SARS-CoV-2 antibody measurement by enzyme-linked immunosorbent assays (ELISAs). A post hoc Cox proportional hazards regression model was performed to identify factors associated with increased risk for seropositivity.
Results:
In total, 1,740 employees were enrolled. At 6 months, the cumulative seroprevalence was 5.3%, which was below estimated community point seroprevalence. Seroprevalence was 5.8% among employees who provided direct care and was 3.4% among employees who did not perform direct patient care. Most participants who were seropositive at baseline remained positive at follow-up assessments. In a post hoc analysis, direct patient care (hazard ratio [HR], 1.95; 95% confidence interval [CI], 1.03–3.68), Black race (HR, 2.70; 95% CI, 1.24–5.87), and exposure to a confirmed case in a nonhealthcare setting (HR, 4.32; 95% CI, 2.71–6.88) were associated with statistically significant increased risk for seropositivity.
Conclusions:
Employee SARS-CoV-2 seroprevalence rates remained below the point-prevalence rates of the surrounding community. Provision of direct patient care, Black race, and exposure to a confirmed case in a nonhealthcare setting conferred increased risk. These data can inform occupational protection measures to maximize protection of employees within the workplace during future COVID-19 waves or other epidemics.
The Subglacial Antarctic Lakes Scientific Access (SALSA) Project accessed Mercer Subglacial Lake using environmentally clean hot-water drilling to examine interactions among ice, water, sediment, rock, microbes and carbon reservoirs within the lake water column and underlying sediments. A ~0.4 m diameter borehole was melted through 1087 m of ice and maintained over ~10 days, allowing observation of ice properties and collection of water and sediment with various tools. Over this period, SALSA collected: 60 L of lake water and 10 L of deep borehole water; microbes >0.2 μm in diameter from in situ filtration of ~100 L of lake water; 10 multicores 0.32–0.49 m long; 1.0 and 1.76 m long gravity cores; three conductivity–temperature–depth profiles of borehole and lake water; five discrete depth current meter measurements in the lake and images of ice, the lake water–ice interface and lake sediments. Temperature and conductivity data showed the hydrodynamic character of water mixing between the borehole and lake after entry. Models simulating melting of the ~6 m thick basal accreted ice layer imply that debris fall-out through the ~15 m water column to the lake sediments from borehole melting had little effect on the stratigraphy of surficial sediment cores.
The first demonstration of laser action in ruby was made in 1960 by T. H. Maiman of Hughes Research Laboratories, USA. Many laboratories worldwide began the search for lasers using different materials, operating at different wavelengths. In the UK, academia, industry and the central laboratories took up the challenge from the earliest days to develop these systems for a broad range of applications. This historical review looks at the contribution the UK has made to the advancement of the technology, the development of systems and components and their exploitation over the last 60 years.
