Explotación de ungulados en ambientes ecotonales de Patagonia: Zooarqueología de un basural del Holoceno medio, sitio Cerro Casa de Piedra 7 (Santa Cruz, Argentina)
Authors: Fernández Natalia Lucía 
Published: February 2023

ResumenEn este trabajo se discuten las estrategias de explotación de ungulados por parte de los grupos cazadores-recolectores que habitaron los sectores ecotonales del Parque Nacional Perito Moreno (Santa Cruz, Argentina). La importancia del guanaco (Lama guanicoe) y el huemul (Hippocamelus bisulcus) en la subsistencia de estos sectores precordilleranos se mantuvo constante desde la transición Pleistoceno/Holoceno. La muestra analizada corresponde a un basural datado en el Holoceno medio (ca. 5500 años aP) perteneciente al sitio Cerro Casa de Piedra 7. La variedad de partes anatómicas, junto con la diversidad y frecuencia de marcas de procesamiento, da cuenta de un aprovechamiento integral e intensivo de ambas especies. La explotación del guanaco se habría centrado, principalmente, en grupos familiares con una marcada selectividad de individuos en edad reproductiva. El incremento demográfico en las poblaciones de guanacos ocurrido durante el Holoceno medio, tal como señalan investigaciones moleculares en Patagonia, habría permitido esta interacción predador-presa sin consecuencias ecológicas negativas. En tanto, el huemul tuvo un rol complementario en la dieta y su obtención se basó en una estrategia de caza oportunista, sin causar una presión predatoria significativa sobre esta presa. Las discrepancias en el aprovechamiento responderían a cuestiones etológicas y demográficas propias de estos ungulados.
How Much Have We Changed? Long-Term Determinants of Attitudes toward Homosexuality in Chile

Published: February 2023

AbstractThis study explores the evolution of individual attitudes toward homosexuality in Chile during the period 1998–2018. Based on microdata from the International Social Survey Programme, it finds evidence of a significant rise in the share of people accepting homosexual relationships, from 5.4 percent to 38.5 percent of the population. Observable individual-level socioeconomic characteristics are responsible for only 3.6 percentage points of this shift. In particular, the increase in educational attainment and generational replacement help to explain this trend and account for an increase of 2.6 percentage points (roughly 45 percent of the initial level of acceptance). Nevertheless, the bulk of this shift is due to structural changes in Chilean society, which may have increased acceptance across all the demographic subgroups considered in the analysis.

Abstract
In the present paper, we report the collection of a specimen of the West central Atlantic Stegastes variabilis in the shores of Israel, eastern shore of the Mediterranean. This record was preceded by a record of this species from Malta, in the central Mediterranean. The present record suggests that S. variabilis has established a small population in the Mediterranean.
A new lifetime distribution by maximizing entropy: properties and applications
Authors: Khosravi Tanak Ali , Najafi Marziyeh , Mohtashami Borzadaran G.R. 
Published: February 2023

AbstractThe principle of maximum entropy is a well-known approach to produce a model for data-generating distributions. In this approach, if partial knowledge about the distribution is available in terms of a set of information constraints, then the model that maximizes entropy under these constraints is used for the inference. In this paper, we propose a new three-parameter lifetime distribution using the maximum entropy principle under the constraints on the mean and a general index. We then present some statistical properties of the new distribution, including hazard rate function, quantile function, moments, characterization, and stochastic ordering. We use the maximum likelihood estimation technique to estimate the model parameters. A Monte Carlo study is carried out to evaluate the performance of the estimation method. In order to illustrate the usefulness of the proposed model, we fit the model to three real data sets and compare its relative performance with respect to the beta generalized Weibull family.
Manufacturing a Protestant Consensus: Religion and Regime Entrenchment in the Eisenhower Era
Authors: Compton John W. 
Published: February 2023

AbstractThe party regime concept is central to the study of American political development. Yet many questions about the processes through which party regimes are created, maintained, and dismantled remain unanswered. This article argues that religious bodies have historically played an important role in these processes. Specifically, I demonstrate that “mainline” Protestant groups made three distinct contributions to the entrenchment of the post–New Deal Democratic regime. First, the National Council of Churches (NCC) credibly reframed Democratic policy commitments as embodying universal values (as opposed to the preferences of favored interest groups). Second, the NCC's economic policy arm, which included representatives from business, labor, and the clergy, successfully created the impression of an overwhelming elite consensus in favor of center-left economic policies. Third, the NCC used its moral authority to empower the moderate Republican opposition while simultaneously marginalizing the party's well-funded and potentially influential right wing. The NCC was one of many civil society groups that opposed the GOP right's attempts to roll back the New Deal. But the professional diversity of its membership, its ability to frame its pronouncements in religious terms, and its links to the Protestant grassroots made it arguably the most effective.

Abstract
Persons experiencing homelessness (PEH) or rough sleeping are a vulnerable population, likely to be disproportionately affected by the coronavirus disease 2019 (COVID-19) pandemic. The impact of COVID-19 infection on this population is yet to be fully described in England. We present a novel method to identify COVID-19 cases in this population and describe its findings. A phenotype was developed and validated to identify PEH or rough sleeping in a national surveillance system. Confirmed COVID-19 cases in England from March 2020 to March 2022 were address-matched to known homelessness accommodations and shelters. Further cases were identified using address-based indicators, such as NHS pseudo postcodes. In total, 1835 cases were identified by the phenotype. Most were <39 years of age (66.8%) and male (62.8%). The proportion of cases was highest in London (29.8%). The proportion of cases of a minority ethnic background and deaths were disproportionality greater in this population, compared to all COVID-19 cases in England. This methodology provides an approach to track the impact of COVID-19 on a subset of this population and will be relevant to policy making. Future surveillance systems and studies may benefit from this approach to further investigate the impact of COVID-19 and other diseases on select populations.

Published: February 2023

AbstractTheobroma cacao L. (cacao) is an important tropical crop used to produce chocolate. Evolutionary relationships between cultivated and wild cacao genotypes and their genetic diversity are poorly understood. Exploring phylogenetic diversity and spatial patterns of both cultivated and crop wild relatives can improve the knowledge of the evolutionary history of a crop, giving insights into its cultivation, breeding programmes and conservation. This study identifies biodiversity priority areas in Colombia by calculating phylogenetic diversity indices using a set of 87 single nucleotide polymorphism markers. These were sourced from 279 genotypes conserved in the Corporación Colombiana de Investigación Agropecuaria (Agrosavia) germplasm collection. The Caribbean and North Andes areas exhibited the highest phylogenetic diversity and significantly high relative phylogenetic diversity. We propose that those regions where wild cacao occurs should be prioritized as conservation areas. Besides, cacao lineages that have recently diverged and are present in Arauca, Huila and Nariño areas, with significantly low relative phylogenetic diversity, should be prioritized for breeding programmes. The Amazonia genotypes were closer to the root of the phylogenetic tree, suggesting an older origin than those found in the Andes region. Our study highlights the importance of using T. cacao germplasm from the Amazonia region as a priority to recover relict diversity in breeding programmes and broaden the gene pool of modern cultivated cacao.
Are Ocean Reanalyses Useful for Earth Rotation Research?

Published: February 2023

AbstractOceanic circulation and mass‐field variability play important roles in exciting Earth's wobbles and length‐of‐day changes (ΔΛ), on time scales from days to several years. Modern descriptions of these effects employ oceanic angular momentum (OAM) series from numerical forward models or ocean state estimates, but nothing is known about how ocean reanalyses with sequential data assimilation (DA) would fare in that context. Here, we compute daily OAM series from three 1/4° global ocean reanalyses that are based on the same hydrodynamic core and input data (e.g., altimetry, Argo) but different DA schemes. Comparisons are carried out (a) among the reanalyses, (b) with an established ocean state estimate, and (c) with Earth rotation data, all focusing on the period 2006–2015. The reanalyses generally provide credible OAM estimates across a range of frequencies, although differences in amplitude spectra indicate a sensitivity to the adopted DA scheme. For periods less than 120 days, the reanalysis‐based OAM series explain ∼40%–50% and ∼30%–40% of the atmosphere‐corrected equatorial and axial geodetic excitation, similar to what is achieved with the state estimate. We find mixed performance of the reanalyses in seasonal excitation budgets, with some questionable mean ocean mass changes affecting the annual cycle in ΔΛ. Modeled excitations at interannual frequencies are more uncertain compared to OAM series from the state estimate and show hints of DA artifacts in one case. If users are to choose any of the tested reanalyses for rotation research, our study points to the Ocean Reanalysis System 5 as the most sensible choice.

Published: February 2023

AbstractSuspended particle transport is frequently involved in many geophysical processes and subsurface engineering applications. Although common and important, the effect of liquid cohesion on particle clogging has been overlooked in previous studies. We conduct visualized experiments of dilute suspension flow in a rough fracture and find a dramatic enhancement of clogging by a tiny amount of additional immiscible wetting liquid, even at weight percentage ω ≤ 0.5%. An experimental phase diagram of clogging patterns is obtained in the space of secondary liquid content and flow rate. The combined effect of suspension composition and hydrodynamic condition on the clogging behavior is analyzed to explain transitions of clogging regimes. A theoretical model of agglomerate size is proposed to quantify the capillary cohesion effect. This work improves the understanding of fines migration and particle‐clogging behaviors in the subsurface and paves the way for possibility of controlling particle transport and clogging in various applications.

Published: February 2023

AbstractDrake Passage is a key region for transport between the surface and interior ocean, but a mechanistic understanding of this exchange remains immature. Here, we present wintertime, submesoscale‐resolving hydrographic transects spanning the southern boundary of the Antarctic Circumpolar Current and the Polar Front (PF). Despite the strong surface wind and buoyancy forcing, a freshwater lens suppresses surface‐interior exchange south of the PF; ventilation is instead localized to the PF. Multiple lines of the analysis suggest submesoscale processes contribute to ventilation at the PF, including small‐scale, O(10 km), frontal structure in water mass properties below the mixed layer and modulation of a surface eddy diffusivity at sub‐50 km scales. These results show that ventilation is sensitive to both submesoscale properties near fronts and non‐local processes, for example, sea‐ice melt, that set stratification and mixed layer properties. This highlights the need for adaptive observing strategies to constrain Southern Ocean heat and carbon budgets.

Published: February 2023

AbstractReleasing diffuse artificial clouds into the space environment using a rocket or spacecraft can modify the natural plasma state. This uses space itself as a laboratory for studying plasma phenomena that cannot be reproduced on the ground. The Space Measurement of A Rocket‐released Turbulence (SMART) mission will inject a beam of barium neutral vapor into the ionosphere and perpendicular to the Earth's magnetic field. Barium atoms will be photoionized, forming an ion ring distribution that is unstable to lower hybrid waves. Large amplitude lower hybrid waves nonlinearly scatter to whistler and magnetosonic waves that can propagate out to the magnetosphere. This paper details the theory, modeling, and simulation we used to design this release experiment to optimize the energy in the plasma waves under a variety of constraints. A product of this analysis is quantitative predictions for some in situ and remote measurements. Hydrocode simulations of barium vapourization and acceleration via shaped charge provide the initial state of the neutral beam. We optimize the apogee, orientation, and position of the payload and instruments. Cloud dynamics are simulated with a direct simulation Monte Carlo technique, which includes photoionization with metastable barium states, collisions with the neutral background atmosphere, optical line emission, gravity, and electromagnetic forces. We predict the plasma density measured by the instrument payload and the remotely measured optical intensity. We also examine how the plasma wave growth differs at the measurement location compared to the bulk of the barium cloud.

AbstractPyrocumulonimbus (PyroCb) clouds have a complex origin dependent on fire dynamics and meteorological conditions. When a pyrocumulonimbus cloud develops and is maintained over a period of time, it can inject significant aerosol into the troposphere and lower stratosphere, resulting in a longer‐term (months to years) occurrence of aerosol in the stratosphere. In this work, we investigate the British Columbia wildfires on 12–13 August 2017 using a multi‐scale simulation framework. We use the output of a physics‐based wildfire model (FIRETEC) with parameterized energy, particle, and gas emissions to drive the upper atmospheric aerosol mass injection within a regional cloud resolving model (HIGRAD). We demonstrate that vertical motions produced by latent heat release of the condensation of ice and cloud particles within the PyroCbs induce another 5 km of lifting of the simulated aerosol plume. Primary black carbon and organic aerosols (OAs) alone may not be enough to explain the observed aerosol burden, thus we show that secondary OA produced via condensation of gases by the fires, ash, and possibly dust can enhance lofted aerosol mass. A simulation with all emission mechanisms active, driven by the observed fuel load and environmental conditions, reasonably reproduces an aerosol profile inferred from observational data.

Published: February 2023

AbstractThe seismic waves emitted during granular flows are generated by different sources: high frequencies by interparticle collisions and low frequencies by global motion and large scale deformation. To unravel these different mechanisms, an experimental study has been performed on the seismic waves emitted by dry, dense, quasi‐steady granular flows. The emitted seismic waves were recorded using shock accelerometers and the flow dynamics were captured with a fast camera. The mechanical characteristics of the particle collisions were analyzed, along with the intervals between collisions and the correlations in particles' motion. The high‐frequency seismic waves (1–50 kHz) were found to originate from particle collisions and waves trapped in the flowing layer. The low‐frequency waves (20–60 Hz) were generated by particles' oscillations along their trajectories, that is, from cycles of dilation/compression during coherent shear. The profiles of granular temperature (i.e., the mean squared value of particle velocity fluctuations) and average velocity were measured and related to each other, then used in a simple steady granular flow model, in which the seismic signal consists of the variously attenuated contributions of shear‐induced Hertzian collisions throughout the flow, to predict the rate at which seismic energy was emitted. Agreement with the measured seismic power was reasonable, and scaling laws relating the seismic power, the shear strain rate and the inertial number were derived. In particular, the emitted seismic power was observed to be approximately proportional to the root mean square velocity fluctuation to the power 3.1 ± 0.9, with the latter related to the mean flow velocity.
Persistence of resistance: a panel data analysis of the effect of antibiotic usage on the prevalence of resistance
Authors: Rahman Sakib , Kesselheim Aaron S. , Hollis Aidan 
Published: February 2023

AbstractThe use of antibiotics promotes the emergence of resistant bacteria in the patient and the environment. The extent of this well-documented biological relationship is, however, not well characterized at an ecological level. To make good policy around antibiotic use, it is important to understand the empirical connection between usage and resistance. We provide a consistent approach to estimate this relationship using national-level surveillance data. This paper estimates the effect of antibiotic usage on antibiotic resistance using an 11-year panel of data on both usage and resistance for 26 antibiotic–bacteria combinations in 26 European countries. Using distributed–lag models and event-study specifications, we provide estimates of the rate at which increases in antibiotic usage at the national level affect antibiotic resistance nationally and internationally. We also calculate the persistence of resistance and analyze how resistance behaves asymmetrically with respect to increases and decreases in usage. Our analysis finds the prevalence of resistant bacteria increases immediately after usage and continues to increase for at least 4 years after usage. We show that a decrease in usage has little identifiable impact on resistance over the same period. Usage in neighboring countries increases resistance in a country, independent of usage in that country. Trends in usage-related resistance vary across European regions and across bacterial classifications.

Published: February 2023

AbstractTo evaluate the correlation between chromosomal abnormalities and fetal aberrant right subclavian artery (ARSA) with or without additional ultrasound anomalies (UAs). A total of 340 fetuses diagnosed with ARSA by ultrasound between December, 2015, and July, 2021, were included. All cases were subdivided into three groups: (A) 121 (35.6%) cases with isolated ARSA, (B) 91 (26.8%) cases with soft markers, and (C) 128 (37.6%) cases complicated with other UAs. Invasive testing was performed via amniotic fluid or cord blood karyotyping and chromosomal microarray analysis (CMA) in parallel, and pregnancy outcomes were followed. Karyotype abnormalities were identified in 18/340 (5.3%) patients. Karyotype abnormalities in Groups A, B, and C were 0/121 (0.0%), 7/91 (7.7%), and 11/128 (8.6%), respectively. CMA abnormalities with clinically significant variants were detected in 37/340 (10.9%) cases, of which 22q11.2 deletion syndrome and trisomy 21 accounted for 48.6% (18/37). The overall abnormal CMA with clinically significant variant detection rates in Groups A, B, and C were 3/121(2.5%), 13/91 (14.3%), and 21/128 (16.4%), respectively. There were significant difference in clinically significant CMA anomalies detection rate between Groups A and C (p < 0.05), as well as Groups A and B (p < 0.05). Comparing CMA to karyotyping showed a clinically significant incremental yield in Group C (7.8%, 10/128) compared to Groups A (2.5%, 3/121) and B (6.6%, 6/91) (p > 0.05). Fetal ARSA with additional UAs, concurred with cardiac and extra-cardiac anomalies, constitutes a high-risk factor for chromosomal aberrations, especially for pathogenic or likely pathogenic copy number variants.
Distribution of energy in the ideal gas that lacks equipartition
Authors: Naplekov Dmitry M. , Yanovsky Vladimir V. 
Published: February 2023

AbstractThe energy and velocity distributions of ideal gas particles were first obtained by Boltzmann and Maxwell in the second half of the nineteenth century. In the case of a finite number of particles, the particle energy distribution was obtained by Boltzmann in 1868. However, it appears that this distribution is not valid for all vessels. A round vessel is a special case due to the additional integral of motion, the conservation of the gas angular momentum. This paper is intended to fill this gap, it provides the exact distribution of particle energy for a classical non-rotating ideal gas of a finite number of colliding particles in a round vessel. This previously unknown distribution was obtained analytically from the first principles, it includes the dependence on all the particle masses. The exact mean energies of gas particles are also found to depend on the system parameters, i.e., the distribution of energy over the degrees of freedom is not uniform. Therefore, the usual ideal gas model allows for the uneven energy partitioning, which we study here both theoretically and in simple numerical experiments.
