The Orchestra as Acting Area in Greek Tragedy
Authors: Ley Graham , Ewans Michael 
Published: September 2020

For some years past there has been a welcome change of emphasis towards the consideration of staging in books published on Greek tragedy; and yet with that change also a curious failure to be explicit about the central problem connected with all stagecraft, namely that of the acting-area. In this study two scholars with considerable experience of teaching classical drama in performance consider this problem of the acting-area in close relation to major scenes from two Greek tragedies, and suggest some general conclusions. The article must stand to some extent as a critique of the succession of books that has followed the apparently pioneering study of Oliver Taplin, none of which has made any substantial or sustained attempt to indicate where actors might have acted in the performance of Greek tragedy, though most, if not all, have been prepared to discard the concept of a raised ‘stage’ behind the orchestra.
Hippolytus (428 BC) is the earliest of the surviving plays of Euripides to involve three speaking actors in one scene. Both Alcestis (438 BC and Medea (431 BC almost certainly require three actors to be performed with any fluency, but surprisingly present their action largely through dialogue and confrontation — surprisingly, perhaps, because at least since 458 BC and the performance of the Oresteia it is clear that three actors were available to any playwright.
Sensitivity to Shame in Greek and Roman Epic, with Particular Reference to Claudian and Nonnus
Authors: Newbold R. F. 
Published: September 2020

English shame and German scham derive from the Gothic schama, ‘to hide, cover, conceal’. German Hemd (shirt) and English and French chemise are other derivatives. In some languages the word for ‘shame’ and the word for ‘wound’ are the same. A wound exposes and can thereby advertise vulnerabilty and a cause for shame. Hiding or covering may seek to guard against wounding, humiliating exposure.
Shame is self-evidently an important human emotion. Insofar as animals are innocent of shame, experience of it is a mark of humanity. Much human behaviour is influenced by fear of shame and embarrassment. Living in the face and eyes, shame is very close to the experienced self. Self-image and self-esteem are heavily determined by one's susceptibility to shame. Experience of shame is impossible without a sense of individuation, without a sense of discreteness from the world and of being an object in the eyes of another. Study of shame sensitivity therefore offers many clues to an individual's or a culture's behaviour, sense of identity and relationship to the environment.
Post-operative discharge education for parent caregivers of children with congenital heart disease: a needs assessment
Authors: Mannarino Candace N. , Michelson Kelly , Jackson Lindsay , Paquette Erin , McBride Mary E. 
Published: September 2020

AbstractObjective:Children with congenital heart disease (CHD) have complex unique post-operative care needs. Limited data assess parents’ hospital discharge preparedness and education quality following cardiac surgery. The goals were to identify knowledge gaps in discharge preparedness after congenital heart surgery and to assess the acceptability of an educational mobile application to improve discharge preparedness.Methods:Telephonic interviews with parents of children with two-ventricle physiology who underwent cardiac surgery 5–7 days post-discharge and in-person interviews with clinicians were conducted. We collected parent and clinician demographics, parent health literacy information and patient clinical data. We analysed interview transcripts using summative content analysis.Results:We interviewed 26 parents and 6 clinicians. Twenty-two of the 26 (85%) parents felt ready for discharge; 4 of the 6 (67%) clinicians did not feel most parents were ready for discharge. Fifteen of the 26 parents (58%) reported receiving the majority of discharge teaching on the day of discharge. Eight parents did not feel like all of their questions were answered. Most parents (14/26, 54%) preferred visual educational learning aids and could accurately describe important aspects of care. Most parents (23/26, 88%) and all 6 clinicians felt a mobile application for post-operative care education would be helpful.Conclusions:Most parents received education on the day of discharge and could describe the information they received prior to discharge, although there were some preparedness gaps identified after discharge. Clinicians and parents varied in their perceptions of the readiness for discharge. Most responses suggest that a mobile application for discharge education may be helpful for transition to home.
Pregnancy and early post-natal outcomes of fetuses with functionally univentricular heart in a low-and-middle-income country

Published: September 2020

AbstractBackground:Care of children with functionally univentricular hearts is resource-intensive.Objectives:To analyse pregnancy and early post-natal outcomes of fetuses with functionally univentricular hearts in the setting of a low–middle-income country.Methods:A retrospective study was conducted during the period of January 2008–October 2019. Study variables analysed included gestational age at diagnosis, maternal and fetal comorbidities and cardiac diagnosis including morphologic type of single ventricle. Outcomes analysed included pregnancy outcomes, type of post-natal care and survival status on the last follow-up.Results:A total of 504 fetuses were included. Mean maternal age was 27.5 ± 4.8 years and mean gestational age at diagnosis was 25.6 ± 5.7 weeks. Pregnancy outcomes included non-continued pregnancies (54%), live births (42.7%) and loss to follow-up (3.3%). Gestational age at diagnosis was the only factor that impacted pregnancy outcomes (non-continued pregnancies 22.5 ± 3.5 vs. live births 29.7 ± 5.7 weeks; p < 0.001). Of the 215 live births, intention-to-treat was reported in 119 (55.3%) cases; of these 103 (86.6%) underwent cardiac procedures. Seventy-nine patients (36.7%) opted for comfort care. On follow-up (median 10 (1–120) months), 106 patients (21%) were alive. Parental choice of intention-to-.treat or comfort care was the only factor that impacted survival on follow-up.Conclusions:Prenatal diagnosis of functionally univentricular hearts was associated with overall low survival status on follow-up due to parental decisions on not to continue pregnancy or non-intention-to-treat after birth. Early detection of these complex defects by improved prenatal screening can enhance parental options and reduce resource impact in low-and-middle-income countries.
Assessing the accuracy of treatment planning system based radiotherapy structure volumes
Authors: Sharma Richa , Sharma Sunil Dutt , Avasthi Devesh Kumar 
Published: September 2020

AbstractAim:The purpose of the present study was to assess the accuracy of radiotherapy (RT) structure volume generated by the Monaco treatment planning system (TPS) for three different computed tomography (CT) slice thicknesses. Further, this study addressed the important issue of ‘different volumes of the same RT structure shown at different places’ in the Monaco TPS. Also, the practical impact of this difference in structure volumes has been studied for brain or head and neck patients.Materials and Methods:Objects of known volumes were scanned with different CT slice thicknesses and contoured as an RT structure in Monaco TPS and two different volumes provided by the TPS for each RT structure were noted and compared with the real volumes of these objects. In addition, correlation was also assessed between TPS provided volumes and real volumes of these objects. The study was further extended to obtain correlation of volumes in cases of organs that exist in pairs (e.g., eye) in the human body.Results:Monaco TPS overestimates structure volumes except for objects with sharp corners. Although, volumes shown at different places of the same structure have nearly a linear correlation, volumes under structure table are more accurate than those shown under dose–volume histogram (DVH) statistics (total volume) table. Difference in magnitude between these two volumes has no correlation if this difference is analysed for paired organs.Findings:This study confirmed that Monaco TPS provides ‘different value at different places’ of the volume of a given contoured structure. It is recommended that this issue should be reviewed and resolved by the supplier.
Reasoning about Cardinal Directions between 3-Dimensional Extended Objects using Answer Set Programming
Authors: Izmirlioglu Yusuf , Erdem Esra 
Published: September 2020

AbstractWe propose a novel formal framework (called 3D-NCDC-ASP) to represent and reason about cardinal directions between extended objects in 3-dimensional (3D) space, using Answer Set Programming (ASP). 3D-NCDC-ASP extends Cardinal Directional Calculus (CDC) with a new type of default constraints, andNCDC-ASP to 3D. 3D-NCDC-ASP provides a flexible platform offering different types of reasoning: Nonmonotonic reasoning with defaults, checking consistency of a set of constraints on 3D cardinal directions between objects, explaining inconsistencies, and inferring missing CDC relations. We prove the soundness of 3D-NCDC-ASP, and illustrate its usefulness with applications.
Perspectives on Asia: is China kitsch?
Authors: Castelli Alberto 
Published: September 2020

AbstractDue to the introduction of the market economy, in the past four decades China has switched from being a “planned country” – planned economy, planned art – into a domestic version of cultural pluralism. Consumerism has refilled the vacuum left by the retreat of Maoist ideology. However, the overwhelming success of mass culture is sided by the progressive marginalization of the intellectuals or elite, featuring a culture that is kitsch in its ideological twist. In China, present-day cultural constructions provide a forum of debate for the identity of the whole nation, no more traditional, and not yet modern. In other words, consumerism and commercialism, triggered by products of market economy, have generated a cultural consumption of redundant bad taste. Kitsch indeed.1
“WE SPEAK BACK!”
Authors: Curington Celeste Vaughan 
Published: September 2020

AbstractA body of scholarship interrogates conventional notions of citizenship, viewing full social inclusion beyond formal status and as a matter of belonging. This paper integrates the perspective of anti-Blackness with that of belonging and theorizes anti-Black non-belonging. Based on more than a year of fieldwork in the Lisbon metropolitan area, I illustrate how the reality of anti-Black non-belonging in Portugal means that African-descendant women are vulnerable to racist, everyday practices in public space that impact their individual and group reality and feelings of national belonging. Employing a counter narrative methodology, I argue that Cape Verdean women’s narratives of anti-Black non-belonging illustrate the agentic strategy that they deploy to carve our alternative modes of belonging as they navigate their everyday lives. Their accounts illustrate the continued need for African-descendant women to draw from their everyday knowledge of domination to employ resistance, whether through their own parenting or through their own reactionary voices in public space. Anti-Black non-belonging is therefore both a form of racialization and a matter of resistance; as African-descendent women are racialized as foreign, non-being, and out of place, they also challenge the ideology of Portuguese anti-racialism that places Africans and African descendants outside of European citizenry.
Landfalling Droughts: Global Tracking of Moisture Deficits From the Oceans Onto Land
Authors: Herrera‐Estrada Julio E. , Diffenbaugh Noah S. 
Published: September 2020

AbstractDroughts threaten food, energy, and water security, causing death and displacement of millions of people and billions of dollars in damages. However, there are still important gaps in the understanding of drought mechanisms and behaviors, inhibiting the accuracy of early‐warning systems designed to protect communities worldwide. We use an object‐tracking algorithm to track clusters of precipitation‐minus‐evaporation moisture deficits across land and ocean areas of the globe from 1981–2018. This analysis reveals a new type of “landfalling drought” that originates over the ocean and “migrates” onto land. We find that 16% of droughts that affected the continents worldwide from 1981–2018 were landfalling droughts. These droughts were significantly larger (220–425%) and more intense (4–30%)—and grew (253–285%) and intensified (9–28%) faster—than droughts that developed solely over the land or ocean. To identify potential underlying mechanisms, we analyze moisture transport associated with landfalling droughts over western North America. We find that landfalling droughts in this region are associated with anomalously anticyclonic atmospheric pressure patterns that reduce moisture fluxes over the Pacific Ocean toward the continent. By advancing understanding of the spatiotemporal evolution of droughts, our findings offer the potential to improve seasonal‐scale prediction and long‐term projection of global drought risks.

Published: September 2020

AbstractDirect and semi‐direct radiative effects of biomass burning aerosols (BBA) from southern and central African fires are still widely debated, in particular because climate models have been unsuccessful in reproducing the low single scattering albedo in BBA over the eastern Atlantic Ocean. Using state‐of‐the‐art airborne in situ measurements and Mie scattering simulations, we demonstrate that low single scattering albedo in well‐aged BBA plumes over southern West Africa results from the presence of strongly absorbing refractory black carbon (rBC), whereas the brown carbon contribution to the BBA absorption is negligible. Coatings enhance light absorption by rBC‐containing particles by up to 210%. Our results show that accounting for the diversity in black carbon mixing state by combining internal and external configurations is needed to accurately estimate the optical properties and henceforth the shortwave direct radiative effect and heating rate of BBA over southern West Africa.
Chemical Reaction Between Metallic Iron and a Limited Water Supply Under Pressure: Implications for Water Behavior at the Core‐Mantle Boundary

Published: September 2020

AbstractWater transportation to the deep lower mantle via plate subduction may induce a reaction between water and iron at the core‐mantle boundary. Recent experimental studies suggest that such a reaction may generate FeO2Hx‐rich domains, which can explain the seismic structures of the ultralow velocity zone in this region. In this study, the chemical reaction between metallic iron and a limited water supply at ~120 GPa was investigated using time‐resolved in situ synchrotron X‐ray diffraction measurements in combination with the laser‐heated diamond anvil cell technique. Contrary to the results of earlier studies, the formation of FeO instead of FeO2Hx without intermediate phases was observed. Considering the unlimited availability of iron in the core and the limited water supply resulting from mantle downflow, the FeO‐rich layers consisted of Fe‐bearing ferropericlase and postperovskite, which must have locally cumulated at the bottom of the mantle simultaneously with hydrogen incorporation into the core.
Highly Heterogeneous Pore Fluid Pressure Enabled Rupture of Orthogonal Faults During the 2019 Ridgecrest Mw7.0 Earthquake
Authors: Shi Qibin , Wei Shengji 
Published: September 2020

AbstractHere, we show that the 2019 Mw7.0 Ridgecrest mainshock as well as its Mw6.5 foreshock ruptured orthogonal conjugate faults. We invert the waveforms recorded by the dense strong motion network at relatively high frequencies (up to 1 Hz for P; 0.25 Hz for S) to derive multiple‐point source models for both events, aided by path calibrations from a Mw5.4 and a Mw5.5 earthquake. We demonstrate that the mainshock started from a shallow (3 km) depth with a Mw5.2 event and ruptured the main fault branches oriented in the NW‐SE direction. At ~11 s, two Mw6.2 subevents took place on the SW‐NE oriented fault branches that conjugate to the main fault to the NE and SW. The SW branch rupture partially overlapped with the foreshock rupture. We suggest the coseismic rupture on nearly orthogonal faults was enabled by high pore fluid pressure, which greatly weakened the immature fault system in a heterogeneous way.
Present‐Day Crustal Vertical Velocity Field for the Contiguous United States
Authors: Lau Nicholas , Borsa Adrian A. , Becker Thorsten W. 
Published: September 2020

AbstractThe study of vertical crustal motion in the contiguous United States (CONUS) has traditionally focused on the high‐amplitude deformation caused by glacial isostatic adjustment. To better understand more subtle vertical crustal motion resulting from other geophysical processes, we take advantage of the ongoing expansion of continuous Global Positioning System (GPS) networks, whose geodetic observations provide ever‐increasing accuracy and spatial resolution of surface deformation. Using position data for 2,782 GPS stations operating between 2007 and 2017, we produce a new vertical crustal velocity field for the CONUS region. We estimate our own station velocities to ensure consistent treatment of time series outliers, noise, and offsets, and we use adaptive smoothing and interpolation to account for spatially varying station density. Our velocity field reveals spatially coherent vertical features that are representative of regional tectonics, hydrologic, and anthropogenic processes. By removing the effects of modeled glacial isostatic adjustment and hydrologic loading estimated from Gravity Recovery and Climate Experiment (GRACE) data, we reduce the variance in our velocity field by 36% and show residuals potentially due to geocenter motion and underlying tectonics.

Published: September 2020

Observations of ice shelf anisotropy on borehole seismic data are presented. Hot‐water‐drilledboreholes were made by the Aotearoa New Zealand Ross Ice Shelf Programme through a grounding‐line proximal site at Windless Bight and the central Ross Ice Shelf site HWD‐2. The boreholes were used to freeze seismometers into the ice at different depths. Seismic observations of shear wave splitting were made on the borehole seismometers using active sources deployed at the surface. These shear wave splitting data were used to constrain anisotropic ice crystallographic preferred orientations (CPO) within the ice column. Forward models of seismic properties from different CPO geometries are compared to the observations and a best fitting CPO model is found to explain the seismic anisotropy at HWD‐2. This model consists of a vertical girdle of ice c axes that constitute 80% of the CPO in combination with tight horizontal clusters, which contribute 20% of ice c axes. The origin of the modeled CPO is discussed with regard to calculated strain rates at the site and found to be indicative of the current shear kinematics with vertical shear plane and horizontal shear direction. At HWD‐2 the 370 m thick ice shelf is calculated to consist of at least 197 m of anisotropic ice.
Lithospheric Density Structure and Effective Elastic Thickness Beneath Himalaya and Tibetan Plateau: Inference From the Integrated Analysis of Gravity, Geoid, and Topographic Data Incorporating Seismic Constraints

Published: September 2020

AbstractInvestigation of deep crustal and lithospheric structures is essential to understand the nature of geodynamical processes beneath the Himalaya and Tibetan plateau of the India‐Eurasia collision zone. Our density cross sections across the Himalaya‐Eurasia collision zone using integrated 2‐D modeling of gravity, topography, and geoid data incorporating constraints from seismic information supports the above contention. Analysis of gravity, geoid, and elevation data over the interior of the Tibetan plateau predicts complete isostatic compensation, whereas margins of the plateau, having large topographic gradients, show lack of isostatic compensation as the Airy Moho differs from flexural Moho and seismic Moho beneath the Himalaya. Our 2‐D modeled lithospheric cross sections show thick crust (~75 km) and thick lithosphere (~240 km) beneath the Himalayas and southern Tibetan plateau and relatively thin crust (~60 km) and thin lithosphere (~140 km) beneath the northern Tibetan plateau. Therefore, depth of lithosphere‐asthenosphere boundary (LAB) mimics the Moho relief. Thinner crust and thin lithosphere under northern Tibetan plateau suggest the importance of the mantle isostasy where the temperature is anomalously high. This corroborates with the presence of recent potassic volcanism, inefficient Sn propagation, east and southeast oriented global positioning system displacements, and large shear wave splitting anisotropy (>2 s). Excellent correlation between effective elastic thickness and lithospheric thickness predicts hot and deformable lithosphere in the northern Tibet and underthrusting of cold Indian mantle beneath the Himalayas.
A network approach to elucidate and prioritize microbial dark matter in microbial communities

Abstract
Microbes compose most of the biomass on the planet, yet the majority of taxa remain uncharacterized. These unknown microbes, often referred to as “microbial dark matter,” represent a major challenge for biology. To understand the ecological contributions of these Unknown taxa, it is essential to first understand the relationship between unknown species, neighboring microbes, and their respective environment. Here, we establish a method to study the ecological significance of “microbial dark matter” by building microbial co-occurrence networks from publicly available 16S rRNA gene sequencing data of four extreme aquatic habitats. For each environment, we constructed networks including and excluding unknown organisms at multiple taxonomic levels and used network centrality measures to quantitatively compare networks. When the Unknown taxa were excluded from the networks, a significant reduction in degree and betweenness was observed for all environments. Strikingly, Unknown taxa occurred as top hubs in all environments, suggesting that “microbial dark matter” play necessary ecological roles within their respective communities. In addition, novel adaptation-related genes were detected after using 16S rRNA gene sequences from top-scoring hub taxa as probes to blast metagenome databases. This work demonstrates the broad applicability of network metrics to identify and prioritize key Unknown taxa and improve understanding of ecosystem structure across diverse habitats.
