Changing the Subject
Authors: Sundell Timothy 
Published: June 2020

AbstractInFixing Language,Herman Cappelen defends the project of conceptual engineering from a family of objections that he calls “the Strawsonian challenges.” Those objections are all versions of this: “If I ask you a question about theF’s, and you give me an answer that’s not about theF’s but rather about theG’s, then you haven’t answered my question. You have changed the subject.” I argue that Cappelen’s responsesucceedsin reply to one understanding of the Strawsonian challenge—on which it is motivated by ordinary judgments of samesaying and continuity of topic—but that itfailsas a response to another version—on which a parallel objection is motivated by philosophical considerations and is stated in a theoretical register.
Do Paramedics Have a Professional Obligation to Work During a Pandemic? A Qualitative Exploration of Community Member Expectations
Authors: Anderson Cameron , Pooley Julie Ann , Mills Brennen , Anderson Emma , Smith Erin C. 
Published: June 2020

ABSTRACTObjectives:Previous research has identified a lack of clarification regarding paramedic professional obligation to work. Understanding community expectations of paramedics will provide some clarity around this issue. The objective of this research was to explore the expectations of a sample of Australian community members regarding the professional obligation of paramedics to respond during pandemics.Methods:The authors used qualitative methods to gather Australian community member perspectives immediately before the onset of the coronavirus disease 2019 (COVID-19) pandemic. Focus groups were used for data collection, and a thematic analysis was conducted.Results:The findings revealed 9 key themes: context of obligation (normal operations versus crisis situation), hierarchy of obligation (individual versus organizational obligation), risk acceptability, acceptable occupational risk (it’s part of the job), access to personal protective equipment, legal and ethical guidelines, education and training, safety, and acceptable limitations to obligation. The factors identified as being acceptable limitations to professional obligation are presented as further sub-themes: physical health, mental health, and competing personal obligations.Conclusions:The issue of professional obligation must be addressed by ambulance services as a matter of urgency, especially in light of the COVID-19 coronavirus pandemic. Further research is recommended to understand how community member expectations evolve during and after the COVID-19 coronavirus pandemic.

Published: June 2020

AbstractBackground:Most clinical microbiology laboratories have replaced toxin immunoassay (EIA) alone with multistep testing (MST) protocols or nucleic acid amplification testing (NAAT) alone for the detection of C. difficile.Objective:Study the effect of changing testing strategies on C. difficile detection and strain diversity.Design:Retrospective study.Setting:A Veterans’ Affairs hospital.Methods:Initially, toxin EIA testing was replaced by an MST approach utilizing a glutamate dehydrogenase (GDH) and toxin EIA followed by tcdB NAAT for discordant results. After 18 months, MST was replaced by a NAAT-only strategy. Available patient stool specimens were cultured for C. difficile. Restriction endonuclease analysis (REA) strain typing and quantitative in vitro toxin testing were performed on recovered isolates.Results:Before MST (toxin EIA), 79 of 708 specimens (11%) were positive, and after MST (MST-A), 121 of 517 specimens (23%) were positive (P < .0001). Prior to NAAT-only testing (MST-B), 80 of the 490 specimens (16%) were positive by MST, and after NAAT-only testing was implemented, 67 of the 368 specimens (18%) were positive (P = nonsignificant). After replacing toxin EIA testing, REA strain group diversity increased (8, 13, 13, and 10 REA groups in the toxin EIA, MST-A, MST-B, and NAAT-only periods, respectively) and in vitro toxin concentration decreased. The average log10 toxin concentration of the isolates were 2.08, 1.88, 1.20 and 1.55 ng/mL for the same periods, respectively.Conclusions:MST and NAAT had similar detection rates for C. difficile. Compared to toxin testing alone, they detected increased diversity of C. difficile strains, many of which were low toxin producing.
Authoritarian media and diversionary threats: lessons from 30 years of Syrian state discourse
Authors: Alrababa'h Ala’ , Blaydes Lisa 
Published: June 2020

AbstractScholars have long argued that leaders manipulate foreign policy, sometimes even initiating wars in order to enhance their domestic political position. But diversionary wars are relatively rare given the high costs of conflict. In this project, we examine data from major Syrian daily newspapers over a 30-year period (1987–2018) to explore how autocratic regimes use diversionary rhetoric. We find that before the 2011 Arab Uprisings, Syria's state-controlled media concentrated on Israel as a security and political threat. Emphasis on Israel as a diversionary threat decreased during peace negotiations between Syria and Israel, probably in a bid to prepare the Syrian public for normalization of bilateral relations. After 2011, scrutiny of Israel—and other long-standing topics of state discourse—was displaced by discussion of foreign plots and conspiracies against the Syrian state. Our analysis illustrates how authoritarian regimes make use of diversionary strategies as well as how political shocks generate discontinuities in authoritarian rhetoric.
Detrital zircon provenance of north Gondwana Palaeozoic sandstones from Saudi Arabia
Authors: Meinhold Guido , Bassis Alexander , Hinderer Matthias , Lewin Anna , Berndt Jasper 
Published: June 2020

AbstractWe present the first comprehensive detrital zircon U–Pb age dataset from Palaeozoic sandstones of Saudi Arabia, which provides new insights into the erosion history of the East African Orogen and sediment recycling in northern Gondwana. Five main age populations are present in varying amounts in the zircon age spectra, with age peaks at 625 Ma, 775 Ma, 980 Ma, 1840 Ma and 2480 Ma. Mainly igneous rocks of the Arabian–Nubian Shield are suggested to be the most prominent sources for the Ediacaran to middle Tonian zircon grains. Palaeoproterozoic and Archaean grains may be xenocrystic zircons or they have been recycled from older terrigenous sediment. A primary derivation from Palaeoproterozoic and Archaean basement is also possible, as rocks of such age occur in the vicinity. Approximately 4 % of the detrital zircons show Palaeozoic (340–541 Ma) ages. These grains are likely derived from Palaeozoic post-orogenic and anorogenic igneous rocks of NE Africa and Arabia. A few single grains gave up to Eoarchaean (3.6–4.0 Ga) ages, which are the oldest zircons yet described from Arabia and its vicinity. Their origin, however, is yet unknown. Detrital zircons with U–Pb ages of 1.0 Ga are present in varying amounts in all of the samples and are a feature of terrigenous sediment belonging to the Gondwana super-fan system with an East African – Arabian zircon province.
Omnisubjectivity and the problem of creepy divine emotions
Authors: MULLINS R. T. 
Published: June 2020

AbstractOver the past century, divine passibility has become the majority view within Christian theology and philosophy of religion. Yet it faces a serious objection from proponents of impassibility that I shall call the Problem of Creepy Emotions. In this article, I shall develop the objection in detail, and explore two ways for divine passibilists to answer this objection. I shall do this in several steps. First, I will offer some brief historical remarks to help readers understand that divine empathy is the watershed issue in the debate over impassibility and passibility. In particular, impassibility denies that God has empathy, whereas passibility affirms that God has empathy. Second, I provide definitions of important concepts for this debate such as impassibility, passibility, emotions, and empathy. I shall articulate Linda Zagzebski's recent account of passibility called omnisubjectivity, or perfect empathy. Third, I shall examine the Problem of Creepy Emotions that arises from the affirmation that God has perfect empathy. Fourth, I shall explore two different strategies that divine passibility can employ to avoid the Problem of Creepy Emotions.
Telepsychiatry in the Age of COVID: Some Ethical Considerations
Authors: CHIN H. PAUL , PALCHIK GUILLERMO 
Published: June 2020

AbstractThe COVID-19 pandemic has necessitated a rapid escalation in the use of telepsychiatry. Herein we revisit some of the ethical issues regarding its use, including patient benefice, distributive justice, privacy, and autonomy. Based on these considerations we would hold that telepsychiatry is a vital aspect of providing psychiatric care, and ethically should be offered as a format for treatment, likely beyond the pandemic period. Investigative and advocacy efforts will need to continue to determine its exact role within psychiatric care, and expand its availability for those most in need.

Published: June 2020

AbstractObjective:To examine the associations between serum 25-hydroxyvitamin D (25(OH)D) levels and serum liver enzymes in a representative sample of US adults.Design:The cross-sectional study sample consisted of 24 229 adults with data on serum 25(OH)D levels and serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP) and gamma-glutamyl transaminase (GGT) concentrations, in addition to data on other potential confounders. Multivariate logistic regression and linear regression were applied to assess the associations between serum 25(OH)D levels and ALT, AST, ALP and GGT concentrations.Setting:The National Health and Nutrition Examination Survey, 2001–2006.Participants:The cross-sectional study sample consisted of 24 229 adults.Results:We found a significant association between low serum 25(OH)D levels (<30 nmol/l) and ALP levels in all participants (OR 2·67; 95 % CI 1·98, 3·59; P < 0·001), a confirmed healthy population (OR 3·02; 95 % CI 2·25, 4·07; P < 0·001) and individuals with viral hepatitis (OR 2·87; 95 % CI 1·52, 5·44; P = 0·006) compared with those who had normal 25(OH)D levels (>50 nmol/l). Moreover, in both the logistic regression and linear regression, the associations between 25(OH)D levels and ALP levels were stronger in the subgroups with obesity. No association was present between ALT, AST or GGT levels and serum 25(OH)D levels in this population.Conclusions:The results of the present study provide epidemiological evidence that vitamin D deficiency is associated with liver ALP levels in humans. This finding suggests a potential adverse effect of low 25(OH)D levels on human liver function. However, the underlying mechanisms still need further investigation.

Published: June 2020

AbstractObjective:To understand how dietary intake data collected via a brief ecological momentary assessment (EMA) measure compares to that of data collected via interviewer-administered 24-h dietary recalls, and explore differences in level of concordance between these two assessment types by individual- and meal-level characteristics.Design:Parents completed three 24-h dietary recalls and 8 d of brief EMA surveys on behalf of their child; in total, there were 185 d where dietary intake data from both EMA and 24-h recall were available. The EMA measure asked parents to indicate whether (yes/no) their child had consumed any of the nine total food items (e.g. fruit, vegetable, etc.) at eating occasions where both the child and parent were present.Setting:Twenty-four-hour dietary recalls were completed in person in the study participant’s home; participants completed EMA surveys using a study provided in iPad or their personal cell phone.Participants:A diverse, population-based sample of parent–child dyads (n 150).Results:Among meals reported in both the EMA and dietary recalls, concordance of reporting of specific types of food ranged from moderate agreement for meat (kappa = 0·55); fair agreement for sweets (kappa = 0·38), beans/nuts (kappa = 0·37), dairy (kappa = 0·31), fruit (kappa = 0·31) and vegetables (kappa = 0·27); and little to no agreement for refined grains, whole grains and sweetened beverages (73 % overall agreement; kappa = 0·14). Concordance of reporting was highest for breakfast and snacks, as compared with other eating occasions. Higher concordance was observed between the two measures if the meal occurred at home.Conclusions:Data suggest that among meals reported in both the EMA and dietary recalls, concordance in reporting was reasonably good for some types of food but only fair or poor for others.

Published: June 2020

AbstractObjectives:Brazilians comprise a rapidly growing immigrant Latino group in the USA, yet little research has focused on health issues affecting Brazilian children in immigrant families. As increasing evidence is documenting fathers’ influential role in their children’s eating behaviours and ultimately weight status, the current study sought to explore the Brazilian immigrant fathers’ perspectives and practices related to child’s feeding practices and their preschool-aged children’s eating.Design:Qualitative study using in-depth, semi-structured interviews. Interviews were conducted in Portuguese by native Brazilian research staff using a semi-structured interview guide. Interviews were audio-recorded and transcribed verbatim. Transcripts were analysed thematically using a hybrid approach that incorporated deductive and inductive analytical approaches.Setting:Massachusetts.Participants:Twenty-one Brazilian immigrant fathers who had at least one child aged 2–5 years.Results:Results revealed fathers’ awareness of the importance of healthy eating for their children, their influence as role models and their involvement in feeding routines of their preschool-aged children. Moreover, fathers were receptive to participating in family interventions to promote their children’s healthy eating. Nearly all fathers reported wanting to learn more and to do ‘what’s right’ for their children.Conclusions:The current study provides new information about Brazilian immigrant fathers’ views about factors influencing their children’s healthy eating behaviours and paternal feeding practices. Future research should quantify fathers’ feeding styles and practices and solicit fathers’ input in the design of culturally appropriate family interventions targeting the home environment of preschool-aged children of Brazilian immigrant families.
When Do Voters Sanction Corrupt Politicians?
Authors: Klašnja Marko , Lupu Noam , Tucker Joshua A. 
Published: June 2020

Abstract
A growing body of research explores the factors that affect when corrupt politicians are held accountable by voters. Most studies, however, focus on one or few factors in isolation, leaving incomplete our understanding of whether they condition each other. To address this, we embedded rich conjoint candidate choice experiments into surveys in Argentina, Chile, and Uruguay. We test the importance of two contextual factors thought to mitigate voters’ punishment of corrupt politicians: how widespread corruption is and whether it brings side benefits. Like other scholars, we find that corruption decreases candidate support substantially. But, we also find that information that corruption is widespread does not lessen the sanction applied against corruption, whereas information about the side benefits from corruption does, and does so to a similar degree as the mitigating role of permissible attitudes toward bribery. Moreover, those who stand to gain from these side benefits are less likely to sanction corruption.
Rewetting Offers Rapid Climate Benefits for Tropical and Agricultural Peatlands But Not for Forestry‐Drained Peatlands
Authors: Ojanen Paavo , Minkkinen Kari 
Published: June 2020

AbstractPeat soils drained for agriculture and forestry are important sources of carbon dioxide and nitrous oxide. Rewetting effectively reduces these emissions. However, rewetting also increases methane emissions from the soil and, on forestry‐drained peatlands, decreases the carbon storage of trees. To analyze the effect of peatland rewetting on the climate, we built radiative forcing scenarios for tropical peat soils, temperate and boreal agricultural peat soils, and temperate and boreal forestry‐drained peat soils. The effect of tree and wood product carbon storage in boreal forestry‐drained peatlands was also estimated as a case study for Finland. Rewetting of tropical peat soils resulted in immediate cooling. In temperate and boreal agricultural peat soils, the warming effect of methane emissions offsets a major part of the cooling for the first decades after rewetting. In temperate and boreal forestry‐drained peat soils, the effect of rewetting was mostly warming for the first decades. In addition, the decrease in tree and wood product carbon storage further delayed the onset of the cooling effect for decades. Global rewetting resulted in increasing climate cooling, reaching −70 mW (m2 Earth)−1 in 100 years. Tropical peat soils (9.6 million ha) accounted for approximately two thirds and temperate and boreal agricultural peat soils (13.0 million ha) for one third of the cooling. Forestry‐drained peat soils (10.6 million ha) had a negligible effect. We conclude that peatland rewetting is beneficial and important for mitigating climate change, but abandoning tree stands may instead be the best option concerning forestry‐drained peatlands.
A Kalman Filter Time Series Analysis Method for InSAR
Authors: Dalaison M. , Jolivet R. 
Published: June 2020

AbstractEarth orbiting satellites, such as Sentinel 1A‐B, build up an ever‐growing set of synthetic aperture radar images of the ground. This conceptually allows for real‐time monitoring of ground displacements using Interferometric Synthetic Aperture Radar (InSAR), notably in tectonically active regions such as fault zones or over volcanoes. We propose a Kalman filter for InSAR time series analysis (KFTS), an efficient method to rapidly update preexisting time series of displacement with data as they are made available, with limited computational cost. KFTS solves together for the evolution of phase change with time and for a parametrized model of ground deformation. Synthetic tests of the KFTS reveal exact agreement with the equivalent weighted least squares solution and a convergence of descriptive model parameter after the assimilation of about 1 year of data. We include the impact of sudden deformation events such as earthquakes or slow slip events on the time series of displacement. First tests of the KFTS on ENVISAT data over Mt. Etna (Sicily) and Sentinel 1 data around the Chaman fault (Afghanistan, Pakistan) show precise (±0.05 mm) retrieval of phase change when data are sufficient. Otherwise, the optimized parametrized model is used to forecast phase change. Good agreement is found with classic time series analysis solution and GPS‐derived time series. Accurate estimates are conditioned to the proper parametrization of errors so that models and observations can be combined with their respective uncertainties. This new tool is freely available to process ongoing InSAR time series.

AbstractUranium isotopes (238U/235U) have been used widely over the last decade as a global proxy for marine redox conditions. The largest isotopic fractionations in the system occur during U reduction, removal, and burial. Applying this basic framework, global U isotope mass balance models have been used to predict the extent of ocean floor anoxia during key intervals throughout Earth's history. However, there are currently minimal constraints on the isotopic fractionation that occurs during reduction and burial in anoxic and iron‐rich (ferruginous) aquatic systems, despite the consensus that ferruginous conditions are thought to have been widespread through the majority of our planet's history. Here we provide the first exploration of δ238U values in natural ferruginous settings. We measured δ238U in sediments from two modern ferruginous lakes (Brownie Lake and Lake Pavin), the water column of Brownie Lake, and sedimentary rocks from the Silurian‐Devonian boundary that were deposited under ferruginous conditions. Additionally, we provide new δ238U data from core top sediments from anoxic but nonsulfidic settings in the Peru Margin oxygen minimum zone. We find that δ238U values from sediments deposited in all of these localities are highly variable but on average are indistinguishable from adjacent oxic sediments. This forces a reevaluation of the global U isotope mass balance and how U isotope values are used to reconstruct the evolution of the marine redox landscape.

AbstractWe analyze the 2019 sudden stratospheric warming event that occurred in the Southern Hemisphere through its impact on the Antarctic ozone. Using temperature, ozone, and nitric acid data from the Infrared Atmospheric Sounding Interferometer (IASI), our results show that the average increase in stratospheric temperature reached a maximum of 34.4° on 20 September in the [60–90]°S latitude range when compared to the past 3 years. Dynamical parameters suggest a locally reversed and weakened zonal winds and a shift in the location of the polar jet vortex. This led to air masses mixing, to a reduced polar stratospheric clouds formation detected at a ground station, and as such to lower ozone and nitric acid depletion. 2019 total ozone columns for the months of September, October, and November were on average higher by 29%, 28%, and 26%, respectively, when compared to the 11‐year average of the same months.
