AbstractObjectiveOtolaryngologists perform bilateral myringotomy and tube placement for surgical management for otitis media with effusion. This retrospective study aimed to address the extent to which the coronavirus disease 2019 pandemic and season impact the number of bilateral myringotomy and tube placement procedures performed at a tertiary care centre.MethodsA total of 1248 charts of children who underwent bilateral myringotomy and tube placement from January 2018 through February 2021 were reviewed.ResultsThe cohort included 41.6 per cent females and 58.4 per cent males, with 63.7 per cent having private insurance. The median age at surgery was 2.6 years. The spring season had the most bilateral myringotomy and tube placement procedures per week. The number of bilateral myringotomy and tube placement procedures performed per week after the onset of the coronavirus disease 2019 pandemic was significantly lower compared to the years prior. There was no difference in number of intra-operative effusions pre-pandemic versus after the pandemic onset.ConclusionThis study sheds light on the impact of the coronavirus disease 2019 pandemic and seasonality on the rates of tympanostomy tube procedures, vital for understanding the temporality of ear infections.
‘Brainwork practices’: responsibilisation of dementia prevention in Australian aged care discourse
Authors: Chelberg Kristina 
Published: June 2023

Abstract
Successful ageing continues to be a key theme in contemporary ageing discourses, where good physical and cognitive health in older age is an individualised responsibility. This paper explores how Australian aged care stakeholder discourse contributes to constructions of self-responsibility for brain health and dementia prevention in older persons. Brain health advice messages about diet, exercise and ‘brain fitness’ by aged care stakeholders are argued to construct a moral framework of ‘brainwork practices’ to prevent or delay dementia. This study performed discourse analysis of a sample of public online aged care stakeholder documents (N = 170) to reveal three key concepts in discursive constructions of dementia. The first concept characterises dementia as a disastrous force to be opposed; the second is a biomedical concept of dementia as preventable (or able to be delayed) in a ‘successful’ older age, while the third reflects neurocultural ideas that fetishise perfect memory as the best defence against cognitive decline and dementia. Identifying this matrix of responsibilising ‘brainwork practices’ messages by aged care stakeholders makes a contribution within social gerontology to revealing neoliberal conceptions of older age as an outcome of lifestyle and consumer choices, where dementia is constructed as ‘failed’ or ‘unsuccessful’ ageing.
Precision Medicine and Rough Justice: Wicked Problems
Authors: Fleck Leonard M. 
Published: June 2023

AbstractWhat exactly is a “wicked problem”? It is a social or economic problem that is so complex and so interconnected with other issues that it is extraordinarily difficult or impossible to resolve. This is because all proposed resolutions generate equally complex, equally wicked problems. In this essay, I argue that precision medicine, especially in the context of the U.S. healthcare system, generates numerous wicked problems related to distributive justice. Further, I argue that there are no easy solutions to these wicked problems. The need for trade-offs is inescapable. Rough justice is the best outcome we can hope for, and that outcome requires a commitment to processes of public reason that are fair and inclusive.

Published: June 2023

AbstractBackgroundSurvivors of childhood neuroblastoma are at risk of multiple treatment-related health problems (late effects), impacting their quality of life. While late effects and quality of life among Australia and New Zealand (ANZ) childhood cancer survivors have been reported, the outcomes of neuroblastoma survivors specifically have not been reported, limiting critical information to inform treatment and care.MethodsYoung neuroblastoma survivors or their parents (as proxy for survivors <16 years) were invited to complete a survey and optional telephone interview. Survivors’ late effects, risk perceptions, health-care use, and health-related quality of life were surveyed and analyzed using descriptive statistics and linear regression analyses. In-depth interviews explored participants’ experiences, knowledge, and perception of late effects and information needs. Thematic content analysis was used to summarize the data.ResultsThirty-nine neuroblastoma survivors or parents completed questionnaires (median age = 16 years, 39% male), with 13 also completing interviews. Thirty-two participants (82%) reported experiencing at least 1 late effect, most commonly dental problems (56%), vision/hearing problems (47%), and fatigue (44%). Participants reported high overall quality of life (index = 0.9, range = 0.2–1.0); however, more participants experienced anxiety/depression compared to the population norm (50% met criteria versus 25%, χ2 = 13, p < 0.001). Approximately half of participants (53%) believed they were at risk of developing further late effects. Qualitatively, participants reported knowledge gaps in understanding their risk of developing late effects.ConclusionMany neuroblastoma survivors appear to experience late effects, anxiety/depression and have unmet cancer-related information needs. This study highlights important areas for intervention to reduce the impact of neuroblastoma and its treatment in childhood and young adulthood.
Institutions and tax capacity in sub-Saharan Africa
Authors: Tagem Abrams Mbu Enow , Morrissey Oliver 
Published: June 2023

AbstractThis paper contributes to research on the institutional determinants of tax capacity using annual data from 39 sub-Saharan African countries from 1985 to 2018 to construct a measure of tax capacity for each country based on the trend component of the ratio of actual to potential tax revenue. Potential revenue is estimated by a parsimonious tax performance specification, including only variables found to be robust determinants of the tax/GDP ratio. The results show that, on average, tax capacity is high (given potential) and has improved over time (especially for low-income countries). The final stage of analysis selects, from a wide variety of economic and institutional variables, the most important determinants of cross-country variation in tax capacity. Equal distribution of resources is the most important institutional factor associated with greater capacity, consistent with perceptions of equity supporting the fiscal bargain; corruption is associated with lower capacity, consistent with undermining trust in government. Private consumption and resource rents are associated with greater capacity. Other institutional factors are indirectly associated with greater capacity, such as accountability and elements of democracy associated with equity in the allocation and use of public resources.
Estimation of the Nucleation Location and Rupture Extent of the 1850 Xichang, Sichuan, China, Earthquake by Dynamic Rupture Simulations on a Multi‐Segment Stepover Structure

Published: June 2023

AbstractWe simulated the rupture dynamics and ground motion of the 1850 Xichang, China, earthquake on the Zemuhe fault, which consists of the Lijinbao segment, the Dajing segment, the Chechejie segment, and the Songxin segment, with the curved grid finite‐difference method, and compared the simulation results with the field observed data and written records inferred data. We focused on the rupture extent of this earthquake and the effects of the maximum principal stress azimuth and nucleation location on the rupture process and the corresponding damage distribution. Numerical simulation results suggest that the regional maximum principal stress orientation that surrounds the Zemuhe fault was approximately N55°W, which is identical with the azimuth from the stress relief experiment in the neighboring area. Our simulations further imply that the nucleation location is under Lanbiluo. The simulation of this preferred nucleation location model suggests that the rupture propagated through the entire Dajing segment and the Chechejie segment, and the rupture gradually arrested at shallow depths after it transferred to the Lijinbao segment and the Songxin segment. Moreover, the simulation suggests that the rupture on the Chechejie segment was initiated at the surface and then mainly propagated downward due to the free surface effect. In addition, the Xichang earthquake may have exhibited a low rupture velocity on the Dajing segment. Furthermore, our simulation results emphasize the importance of the stepover width in the earthquake dynamics.

AbstractSmoke from wildfires presents one of the greatest threats to air quality, public health, and ecosystems in the United States, especially in the West. Here we quantify the efficacy of prescribed burning as an intervention for mitigating smoke exposure downwind of wildfires across the West during the 2018 and 2020 fire seasons. Using the adjoint of the GEOS‐Chem chemical transport model, we calculate the sensitivities of population‐weighted smoke concentrations in receptor regions, including states and rural environmental justice communities, to fire emissions upwind of the receptors. We find that the population‐weighted smoke exposure across the West during the September 2020 fires was 44 μg/m3 but would have been 20%–30% greater had these wildfires occurred in October or November. We further simulate a set of prescribed burn scenarios and find that controlled burning interventions in northern California and the Pacific Northwest could have reduced the population‐weighted smoke exposure across the western United States by 21 μg/m3 in September 2020, while doing so in all other states would have reduced smoke exposure by only 1.5 μg/m3. Satellite records of large, prescribed burns (>1,000 acres, or 4 km2) reveal that northern California and western Oregon conducted only seven such prescribed fires over a 6‐year period (2015–2020), even though these regions have a disproportionate impact on smoke exposure for rural environmental justice communities and population centers across the West. Our analysis suggests that prioritizing northern California and the Pacific Northwest for prescribed burns might mitigate future smoke exposure.

AbstractSubmarine melting has been implicated in the accelerated retreat of marine‐terminating glaciers globally. Energetic ocean flows, such as subglacial discharge plumes, are known to enhance submarine melting in their immediate vicinity. Using observations and a large eddy simulation, we demonstrate that discharge plumes emit high‐frequency internal gravity waves that propagate along glacier termini and transfer energy to distant regions of the terminus. Our analysis of wave characteristics and their correlation with subglacial discharge forcing suggest that they derive their energy from turbulent motions within the discharge plume and its surface outflow. Accounting for the near‐terminus velocities associated with these waves increases predicted melt rates by up to 70%. This may help to explain known discrepancies between observed melt rates and theoretical predictions. Because the dynamical ingredients—a buoyant plume rising through a stratified ocean—are common to many tidewater glacier systems, such internal waves are likely to be widespread.
Cross‐Property Relationship Between Electrical Resistivity and Elastic Wave Velocity of Crustal Rocks From the Oman Drilling Project Hole GT3A: Implications for in Situ Geophysical Properties of Oceanic Crust

Published: June 2023

AbstractGeophysical properties of oceanic crust are strongly influenced by the presence of cracks. We studied the effects of cracks on the physical properties of oceanic crustal rocks collected from the ICDP Oman Drilling Project Hole GT3A. Electrical resistivity and P‐ and S‐wave velocities were measured under dry and brine‐water‐saturated conditions for each sample. The experimental results reveal that electrical resistivity and elastic wave velocities are differently correlated with porosity. We performed joint inversion of the measured electrical and elastic properties combining an effective medium model by Kachanov and a statistical crack fluid flow model by Guéguen and Dienes with percolation theory. As a result, the variations in electrical and elastic properties can be related to the crack microstructural parameters: crack density and aspect ratio, as well as connectivity of cracks evaluated from crack density. To understand the influence of in situ conditions of oceanic crust, the joint inversion using the proposed cross‐property relationship was performed for geophysical properties obtained by logging measurements at IODP Hole 1256D. Results show the depth variations of resistivity and sonic velocities can be successfully interpreted by decreasing crack porosity and connectivity. Our data and analysis can provide new insights into the interpretation of geophysical data from the oceanic crust at which pore‐fluid plays key roles in various geodynamic activities.

Published: June 2023

AbstractNepal is an actively deforming region due to its tectonic setting that hosts destructive earthquakes including the recent 2015 Mw 7.8 Gorkha earthquake. To better understand the physics of earthquakes and better assess the seismic hazard in the region, a highly resolved 3‐D structure of the crust is essential. This study presents a new 3‐D S‐wave velocity structure of the crust using ambient noise tomography (ANT). In relation to the 2015 earthquake, we show that the lateral variation of S‐wave velocity likely controls the rupture propagation and arrest. This study further constrains crustal discontinuities beneath Nepal including the Main Himalayan Thrust (MHT) using teleseismic P‐wave coda autocorrelation. The MHT geometry correlates well with sizeable low S‐wave velocity zones obtained from the ANT and separated by two ramps. The southernmost first ramp is where the 2015 Gorkha earthquake nucleated that we map up to the source model of the 1934 historical earthquake in Eastern Nepal. The northernmost second ramp is adjacent to the mid‐crustal low velocity zone beneath south Tibet. In between the two ramps, we interpret the horizontal low velocity zone as the interseismic creeping patch of the MHT with down‐dip extent of 50–70 km length and 90–100 km in correspondence with the Mw 7.8 2015 and 8.4 1934 source models, respectively. A systematic mapping of the low‐velocity zones in relation to the MHT integrated with GPS geodesy along with the respective slip from individual past earthquake ruptures can help decipher the paradox of maximum Himalayan earthquake magnitudes.
Relationship Between the Aerosol Loadings Over the Bay of Bengal and the Arabian Sea in the Early Summer and Asian Monsoon Rainfall Anomalies, and the Role of SST Anomalies in the Indian Ocean

Published: June 2023

AbstractTwo relatively long‐term satellite aerosol products during 1983–2020 and 2000–2020 are employed to investigate interannual relationships between anomalous aerosol loadings over the Bay of Bengal (BoB) and Arabian Sea (AS) in the early summer and Asian monsoon rainfall anomalies. It is shown that increased aerosol loading (IAL) over the BoB is primarily attributed to an intensified upstream aerosol transport by anomalous subtropical westerly winds and coincides with local sea surface temperature (SST) cooling due to intensified prevailing wind and the aerosol dimming effect, and vice versa. A deficient rainfall in India tends to concur with a BoB IAL while excessive rainfall with an AS IAL in May and June. In June, a BoB IAL coincides with significantly deficient rainfall in the southwestern China‐Huaihe River Basin primarily linked to an anomalous cyclone off the coast of Southeast China. Meanwhile a related overturning of Walker Circulation is identified to be driven by the contrast of anomalous convective activity between the southeastern Indian‐BoB and the South China Sea‐Philippine Sea. An AS IAL is associated with air warming in North India due to an elevated aerosol semi‐direct effect and remote forcing that reinforces the meridional air temperature gradient. The IAL over the respective BoB and AS in June are both preceded by cold SST anomalies in the western Indian Ocean that can be traced back to the preceding winter, but the corresponding atmospheric circulations driving aerosol‐monsoon interactions differ distinctly. The above aerosol‐monsoon relationships are sustained primarily during 2000–2020 and vague during 1983–2020.
A Hierarchical Temporal Scale Framework for Data‐Driven Reservoir Release Modeling
Authors: Longyang Qianqiu , Zeng Ruijie 
Published: June 2023

AbstractAs an important anthropogenic interference in the hydrologic cycle, reservoir operation behavior remains challenging to be properly represented in hydrologic models, thus limiting the capability of predicting streamflow under the interactions between hydrologic variability and operational preferences. Data‐driven models provide a promising approach to capture relationships embedded in historical records. Similar to hydrologic processes that vary across temporal scales, reservoir operations manifest themselves at different timescales, prioritizing different operation targets to mitigate streamflow variability at a given time scale. To capture the interaction of reservoir operation across time scales, we proposed a hierarchical temporal scale framework to investigate the behaviors of over 300 major reservoirs across the Contiguous United States with a wide range of streamflow conditions. Data‐driven models were constructed to simulate reservoir releases at monthly, weekly, and daily scales, where decisions at short‐term scales interact with long‐term decisions. We found that the hierarchical temporal scale configuration could compensate for the absence of key explanatory variables as model inputs, thereby efficiently capturing the release decisions of reservoirs situated in the west. Model‐based sensitivity analysis shows that for more than one‐third of the studied reservoirs, the release schemes, as a function of decision variables, vary at different time scales, suggesting that operators commonly face complicated trade‐offs to serve multiple designed purposes. The proposed hierarchical temporal scale approach is flexible to incorporate various data‐driven models and decision variables to derive reservoir operation rules, providing a robust framework to understand the feedback between natural streamflow variability and human interferences across time scales.

AbstractA new measurement protocol, labeled Acoustic Mapping Velocimetry (AMV), has been successfully tested for in‐situ estimation of bedload transport features in sandy beds. The AMV has proven efficient in using the dune‐tracking method (DTM) for characterizing the bedform geometry and dynamics as well as for estimation of the rates of bedload transport. Given the novelty of the AMV protocol and its extensive reliance on multiple site‐specific assumptions and user‐defined parameters, a comparison of this emerging technique with other three non‐intrusive DTM‐based methods and analytical predictors is attempted in this paper. The comparison highlights that the AMV estimates are within 22% of the estimates with the other non‐intrusive protocols and up to 98% different from analytical predictions. The observed differences are related to the possible sources of uncertainty in the AMV workflows and to the means to reduce their impact on the targeted estimations.

Published: June 2023

AbstractThe seasonality of circumnavigation of Madden–Julian Oscillation (MJO) events is examined using 42 years of observations, reanalysis, and global model simulations. MJO events are most likely to propagate across the Atlantic Ocean, Africa and back to the equatorial Indian Ocean relatively unweakened during March–April–May and to a lesser extent during September–October–November. During these seasons, referred to as the “long‐rain” and “short‐rain” periods of East African Monsoon (EAM), precipitation is near the equator and extends farthest east toward the Indian Ocean. Moisture budget analysis of a circumnavigating MJO event under real and hypothetical seasonally varying background conditions indicates that the seasonal zonal movement of the zonal component of the background circulation regulates the moistening of MJO crossing from Eastern Africa to the Indian Ocean. Ensembles of Energy Exascale Earth System Model simulations of the MJO event under idealized seasonally varying background state confirm the observed drawbridge‐like role of the EAM in the propagation of MJO.
Contributions of Climate Change and ENSO Variability to Future Precipitation Extremes Over California
Authors: Huang Xingying , Stevenson Samantha 
Published: June 2023

AbstractThe El Niño/Southern Oscillation (ENSO) affects the occurrence frequency and intensity of extreme precipitation through modulations of regional heat and moisture fluxes. California experiences particularly strong ENSO influences and models project different to its extreme precipitation. It remains unclear how diverse projections of future precipitation extremes relate to inter‐model differences for those changing signals. Here, we use “large ensemble” simulations with multiple climate models along with the Coupled Model Intercomparison Project Phase 5 to investigate the range of precipitation extreme changes over California and the influences from ENSO‐related teleconnections. We found that precipitation amount increases are much larger during El Niño relative to La Niña years, mainly caused by the differences in frequency of extreme events during different phases. The ENSO‐driven effect is even larger than the overall climate change signal for the most extreme events, implying uncertainties from inter‐model differences in ENSO‐related SST variability for extreme precipitation changes.
