Published: June 2021

AbstractUnderstanding the nature and value of scientific collaboration is essential for sound management and proactive research policies. One component of collaboration is the composition and diversity of contributing authors. This study explores how ethnic diversity in scientific collaboration affects scientific impact, by presenting a conceptual model to connect ethnic diversity, based on author names, with scientific impact, assuming novelty and audience diversity as mediators. The model also controls for affiliated country diversity and affiliated country size. Using path modeling, we apply the model to the Web of Science subject categoriesNanoscience & Nanotechnology,EcologyandInformation Science & Library. For all three subject categories, and regardless of if control variables are considered or not, we find a weak positive relationship between ethnic diversity and scientific impact. The relationship is weaker, however, when control variables are included. For all three fields, the mediated effect through audience diversity is substantially stronger than the mediated effect through novelty in the relationship, and the former effect is much stronger than the direct effect between the ethnic diversity and scientific impact. Our findings further suggest that ethnic diversity is more associated with short-term scientific impact compared to long-term scientific impact.
Physicochemical indicators of the influence of a lined municipal landfill on groundwater quality: a case study from Poland
Authors: Przydatek Grzegorz , Kanownik Włodzimierz 
Published: June 2021

AbstractThe paper aims to determine the most significant physicochemical indicators of the effects that a lined landfill in southern Poland has had on groundwater quality. The results of the tests of groundwater and leachate water from the landfill for the period 2009 to 2016 were subjected to a detailed statistical analysis based on the 10 physicochemical parameters. A factor analysis was conducted considering the European Union and national requirements for landfills using analytical and statistical tools. The leachate contamination indicators from a landfill were analysed to reveal their interaction with the groundwater. The assessment indicated that there was an elevated and statistically significantly higher electrical conductivity and copper and total organic carbon concentrations in groundwater hydraulically downgradient of the landfill. The assessment also indicated that there were significant differences in the correlations between chemical parameters downgradient of the landfill and that there was a trend of increasing concentrations of some chemical constituents in groundwater. The adverse effects of the landfill were due to the deposited amount of waste exceeding 10 Mg per day. The impact was noticeable despite low and decreasing concentrations of heavy metals (Hg, Cu, Cd, Pb and Zn) in the leachate. The deterioration of the chemical state of the groundwater in the landfill vicinity could result in the extended time of pollutant migration or mass transport in the irrigated soil medium due to the limited efficiency of the leachate intake system or sealing screen after more than 20 years of landfill operation.
Sealant injectivity through void space conduits to assess remediation of well cement failure
Authors: Alkhamis Mohammed , Imqam Abdulmohsin 
Published: June 2021

AbstractThe primary cement of oil and gas wells is prone to fail under downhole conditions. Thus, a remedial operation must be conducted to restore the wellbore integrity and provides zonal isolation. Many types of materials are currently used and/or have the potential to be employed in wellbore integrity applications, including, but not limited to, conventional Portland cement, microfine and ultrafine cement, thermoset materials, and thermoplastic materials. In this study, several types of materials were selected for evaluation: (1) conventional Portland cement, which is the most widely used in remedial operations in the petroleum industry, (2) polymer resin, which is one of the most recent technologies being applied successfully in the field, (3) polymer solutions, and (4) polymer gel, which is a semisolid material that has shown potential in conformance control applications. This work addresses injectivity and the parameters that affect the injectivity of these materials, which to the authors' best knowledge have not been addressed comprehensively in the literature. The results of this study demonstrate the effects of several factors on the injectivity of the sealants: void size, viscosity of the sealant, injection flow rate, and heterogeneity of the void. The results also promote the use of solids-free sealants, such as epoxy resin, in wellbore remedial operations because epoxy resin behaved like Newtonian fluid and can therefore be injected into very small voids with a minimum pressure requirement.
Diagnosestellung und Management von Pseudohypoparathyreoidismus auf Grundlage der neuen internationalen Nomenklatur
Authors: Ertl Diana-Alexandra 
Published: June 2021

ZusammenfassungFast 80 Jahre nach der erstmaligen Beschreibung ist die Diagnose des Pseudohypoparathyreoidismus für viele Ärzte immer noch eine Herausforderung. Die Vielfalt der klinischen Merkmale und des Verlaufs macht die Diagnosestellung kompliziert. Einige der Patient_innen bleiben unerkannt oder werden erst im Erwachsenenalter diagnostiziert. Nachdem der pathophysiologische Mechanismus verstanden wurde, wurde klar, dass auch andere, verwandte Störungen in Betracht gezogen werden sollten, wenn eine Nebenschilddrüsenhormonresistenz oder ein spezifischer Skelettphänotyp auftritt. Rezente Studien haben gezeigt, dass Mutationen in anderen Genen als dem schon bekannten GNAS zu Störungen der PTH/PTHrP-Signalübertragung führen, was einige der gemeinsamen Merkmale des klassischen Pseudohypoparathyreoidismus erklärt. In diesem Artikel fassen wir die aktuellen Literaturdaten zur neuen Nomenklatur der Störungen des PTH/PTHrP-Signalling, deren Diagnostik und Therapie zusammen, und wir unterstreichen die Notwendigkeit eines multidisziplinären Managements der Patienten. Obwohl diese Krankheiten selten sind, weisen sie möglicherweise schwerwiegende und langanhaltende Komplikationen auf. Daher ist es wichtig, dass auch Patient_innen mit milden Symptomen oder diskretem Phänotyp erkannt, diagnostiziert, behandelt und adäquat langzeitbetreut werden.
Who spent their COVID-19 stimulus payment? Evidence from personal finance software in Japan
Authors: Kaneda Michiru , Kubota So , Tanaka Satoshi 
Published: June 2021

AbstractIn response to the COVID-19 crisis, governments worldwide have been formulating and implementing different strategies to mitigate its social and economic impacts. We study the household consumption responses to Japan’s COVID-19 unconditional cash transfer program. Owing to frequent delays in local governments’ administrative procedures, the timing of the payment to households varied unexpectedly. Using this natural experiment, we analyze households’ consumption responses to cash transfers using high-frequency data from personal finance management software that links detailed information on expenditure, income, and wealth. We construct three consumption measures: one captures the baseline marginal propensity to consume (MPC), and the other two are for the lower and the upper bound of MPC. Additionally, we explore heterogeneity in MPCs by household income, wealth, and population characteristics, as well as consumption categories. Our results show that households exhibit immediate and non-negligible positive responses in household expenditure. There is significant heterogeneity depending on various household characteristics, with liquidity constraint status being the most crucial factor, in line with the standard consumption theory. Additionally, this study provides policymakers with insights regarding targeted cash transfer programs, conditioning on labor income, and liquidity constraints.
Pulmonary embolism with chronic obstructive pulmonary disease
Authors: Yang Ruohan , Liu Guiqing , Deng Chaosheng 
Published: June 2021

AbstractChronic obstructive pulmonary disease (COPD) is a common, preventable, and treatable disease. The incidence of COPD is growing annually in China, and it is a significant and growing public health burden. Multivariate analysis showed that COPD was one of the independent risk factors for the occurrence of pulmonary embolism (PE), and the incidence of PE was significantly higher in COPD patients than in normal subjects. However, PE is often overlooked in patients with acute exacerbation of COPD (AECOPD) because there are many similarities in clinical symptoms between PE and AECOPD, which are difficult to distinguish, resulting in the failure of timely treatment and poor prognosis. Therefore, it is of great significance to understand the clinical manifestations, diagnosis, and treatment of COPD combined with PE for making a more accurate diagnosis, providing timely and effective treatment, and improving the prognosis of such patients.

AbstractBackgroundPersons in Arctic regions disproportionately experience depression. Knowledge gaps remain regarding factors associated with depression among adolescents in the Northwest Territories (NWT), Canada, where child and adolescent mental health hospitalizations are nearly 2.5 times the national rate. This study assesses correlates of depression among adolescents in the NWT.MethodsWe conducted a cross-sectional survey with adolescents aged 13–18 in 17 NWT communities. We assessed associations between socio-demographic characteristics, dating violence, food insecurity and depression, measured with the 9-item Patient Health Questionnaire. We conducted ordered logistic regressions to assess associations with no, mild, or moderate/severe depression scores.ResultsParticipants (n= 399; mean age: 14.3,s.d.: 1.3) were mostly Indigenous (79%) and 45% reported food insecurity. Nearly half (47%) reported minimal/no depression symptoms, 25% mild symptoms and 28% moderate/severe symptoms. In multivariate analyses, participants who were cisgender women compared to other genders, sexually diversev. heterosexual, and food insecure had double the odds of more severe depression symptoms. Among those dating, dating violence was associated with double the odds of moderate/severe depression symptoms.ConclusionsFindings support tailored interventions to address material (food insecurity), relational (dating violence) and symbolic (gender and sexual orientation norms) contextual factors associated with depression among adolescents in the NWT.
The effects of an old-age allowance programme on intergenerational interactions in Taiwan: Heterogeneous effects by adult children’s motives for giving

Published: June 2021

AbstractThis study examines the effects of an old-age allowance programme in Taiwan, the Senior Citizens Welfare Living Allowance (SCWLA), on intergenerational financial transfers, living arrangements and contact, as well as the heterogeneity of its effects by adult children’s five types of motives for giving: altruism, exchange, reciprocity, affection, and sense of responsibility. Using 2002, 2004, 2005 and 2006 data from the Panel Study of Family Dynamics, we employed a difference-in-difference individual fixed effect model to compare the outcomes across the treatment (aged 65 and older) and comparison groups (aged 55 to 64) before and after the introduction of SCWLA. Our results indicate that SCWLA crowds in intergenerational contact but does not significantly change financial transfers and co-residence patterns. The increase in intergenerational contact is primarily driven by adult children having lower motives for giving. This suggests that old-age allowances may reduce financial entanglement between adult children and older parents and change the social norm by raising “low motivators’” awareness, respect and concern for elderly. Providing public transfer to the elderly should not be hampered by the fear of distorting family support functions.
A method for autonomous collision-free navigation of a quadrotor UAV in unknown tunnel-like environments
Authors: Elmokadem Taha , Savkin Andrey V. 
Published: June 2021

AbstractUnmanned aerial vehicles (UAVs) have become essential tools for exploring, mapping and inspection of unknown three-dimensional (3D) tunnel-like environments which is a very challenging problem. A computationally light navigation algorithm is developed in this paper for quadrotor UAVs to autonomously guide the vehicle through such environments. It uses sensors observations to safely guide the UAV along the tunnel axis while avoiding collisions with its walls. The approach is evaluated using several computer simulations with realistic sensing models and practical implementation with a quadrotor UAV. The proposed method is also applicable to other UAV types and autonomous underwater vehicles.

State of the science and future research directions in palliative and end-of-life care in paediatric cardiology: a report from the Harvard Radcliffe Accelerator Workshop
Authors: Cousino Melissa K. , Lord Blyth T. , Blume Elizabeth D. 
Published: June 2021

AbstractWorkshop proceedings, priorities, and recommendations from the “State of the Science and Future Directions in Palliative and End-of-Life Care in Pediatric Cardiology,” a Harvard Radcliffe Accelerator Workshop, are detailed. Eight priorities for research were identified, including patient and family decision making, communication, patient and family experience, patient symptom measurement and management, training and curriculum development, teamwork, family hardships and bereavement, and ethical considerations. Barriers to research in this area were also identified: lack of outcome/measurement tools, lack of research funding, small population sizes, lack of effort/protected time for research, undervalued research topic by field and colleagues, and heterogeneous research participant diversity. Priorities and barriers were mostly consistent with those reported by the field of paediatric palliative care at large. These collective, consensus-based findings from diverse, multidisciplinary leaders in the field, as well as parent representatives, provide a catalyst for scientific advancement specific to paediatric and end-of-life care in paediatric cardiology.
Family caregiver grief and post-loss adjustment: A longitudinal cohort study
Authors: Coelho Alexandra , Roberto Magda , Barros Luísa , Barbosa António 
Published: June 2021

AbstractObjectiveIn order to better understand the different grieving trajectories of the family caregivers (FCs), this study aims to examine the evolution of prolonged grief disorder (PGD) symptoms and the predictive role of the caregiving-related factors in the FCs' grieving trajectory from pre- to post-death.MethodA prospective cohort study was carried out with advanced cancer FCs evaluated before death (T1) and 6–12 months post-loss (T2).ResultsParticipants in T1 (n= 156) were mostly female, adult child, or spouse of the care recipient, with a mean age of 51.78 (SD = 13.29). At T2, 87 FCs participated in the survey. PGD prevalence was higher pre-death (38.6%) than in bereavement (33.7%). Of those who met the PGD criteria before death, most also met these criteria after death (n= 26, 61.9%). Psychological distress and caregiver burden were highly correlated with pre-death grief, which in turn played a critical role in mediating the link between psychological distress and bereavement outcome. Great emotional closeness in the relationship was predictive of PGD symptoms persistence. In contrast, the long-term consequences of caregiver burden were not confirmed.Significance of resultsThis study provides evidence for the diversity of individual FC responses and the complex pattern of interactions between caregiving-related factors, relationship quality, and PGD symptoms evolution from pre- to post-death.

AbstractHorizontal wind measurements using meteor radars located at Thumba (8.5°N, 77°E; 2006–2015) Kototabang (0.2°S, 100.3°E; 2002–2017) and Tirupati (13.63°N, 79.4°E; 2013–2017) in the mesosphere‐lower thermosphere (MLT) and Specified Dynamics Whole Atmosphere Community Climate Model (SD‐WACCM) simulations are employed for investigating the diurnal tide variability at quasi‐biennial scales. The model simulations are evaluated using the meteor radar observations at three tropical locations. WACCM simulations could reproduce the seasonal evolution of diurnal tides very well over Thumba and Tirupati but there are small discrepancies over Kototabang. In order to investigate the modulation of the diurnal tide amplitudes in the MLT region by the stratospheric quasi‐biennial oscillation (SQBO), deseasonalized perturbations of diurnal tides and stratospheric winds are analyzed. A very good correspondence is found between meridional diurnal tide perturbation amplitudes and the SQBO with positive tidal perturbations during the eastward phase of SQBO and negative perturbations during the westward phase over Thumba and Tirupati. SQBO modulations of diurnal tides at global scales exhibits a positive correlation between the meridional diurnal tide perturbation with SQBO winds at 20 hPa and a negative correlation with SQBO winds at 70 hPa within ±40° latitude, except over the equator. It is also noted that the equatorial electrojet strength, is modulated by the SQBO over the Thumba, which is a dip equatorial location. The significance of present study lies in evaluating WACCM simulations at tropical locations using meteor radar measurements and in investigating the SQBO modulations of diurnal tides at global scales.
Effect of Glacial/Interglacial Recharge Conditions on Flow of Meteoric Water Through Deep Orogenic Faults: Insights Into the Geothermal System at Grimsel Pass, Switzerland

Published: June 2021

AbstractMany meteoric‐recharged, fault‐hosted geothermal systems in amagmatic orogenic belts have been active through the Pleistocene glacial/interglacial climate fluctuations. The effects of climate‐induced recharge variations on fluid flow patterns and residence times of the thermal waters are complex and may influence how the geothermal and mineralization potential of the systems are evaluated. We report systematic thermal‐hydraulic simulations designed to reveal the effects of recharge variations, using a model patterned on the orogenic geothermal system at Grimsel Pass in the Swiss Alps. Previous studies have shown that fault‐bounded circulation of meteoric water is driven to depths of ∼10 km by the high alpine topography. Simulations suggest that the current single‐pass flow is typical of interglacial periods, during which (a) meteoric recharge into the fault is high (above tens of centimeters per year), (b) conditions are at or somewhat below the critical Rayleigh number, and (c) hydraulic connectivity along the fault plane is extensive (an extent of at least 10 km into increasingly higher terrain is required to explain the 10 km penetration depth). The subcritical condition constrains the bulk fault permeability to <1e‐14 m2. In contrast, the limited recharge during the numerous Pleistocene glaciation events likely induced a layered flow system, with single‐pass flow confined to shallow depths while non‐Rayleigh convection occurred deeper in the fault. The same layering can be observed at low aspect ratios (length/depth) of the fault plane, when the available recharge area limits flux through the fault.
