The Dark Side of Resilience
Authors: Mahdiani Hamideh , Ungar Michael 
Published: February 2021

AbstractIs resilience always adaptive and functional, or can resilience be maladaptive in contexts where it masks vulnerability or prevents effective action to address risk? In this paper, we propose a new reading of resilience research which challenges the prevailing positive perspective and instead proposes that negative aspects of resilience are common. We focus on studying resilience on a spectrum, distinguishing between degrees of functionality by asking three questions: (1) Is there a wrong degree of resilience? (2) Is there a wrong context for resilience? and (3) Is there a wrong type of resilience? We conclude with reflections on the dark side of resilience by differentiating between functional and less functional adaptation in relation to contexts, degrees of risk, and types of resilience shown.

Published: February 2021

AbstractThere have been significant declines in population numbers of many bat species in the United Kingdom, including Natterer’s bats Myotis nattereri, over the last century, largely due to anthropogenic changes. The philopatry, which temperate-zone bats often exhibit to their natal landscapes, in combination with anthropogenic threats, can lead to fragmentation, isolation and sub-division of populations. This may result in bottlenecks and declines in genetic diversity. Multi-scaled research is required to disentangle how the variation in the physical traits of bat species (e.g. affecting flight), as well as their social and behavioural traits (e.g. community size, migration, breeding systems), may affect the genetic health of populations and provide a potential buffer against fragmentation. We used microsatellite markers to characterise the genetic diversity and population structure present in Natterer’s bat colonies to determine whether summer roosting bat colonies were spatially differentiated or part of a meta-population. Analyses of population structure and measures of genetic relatedness suggest spatially differentiated populations of bats exhibit long term site fidelity to summer roosting sites, whilst high genetic diversity at sites indicates gene exchange occurs via swarming sites. Natterer’s bats in northern England may travel greater distances to swarming sites than has been previously documented.

Published: February 2021

AbstractTo promote the development of the western region in China, it is necessary to build an indicator system to scientifically measure the level of sustainable development in Western China. Based on the construction of a sustainable development level evaluation indicator system, this study employs the panel data entropy model to evaluate the sustainable development level of four state-level urban agglomerations in Western China from 2009 to 2018. Then, the geographical detector model is used to measure the spatial heterogeneity degree of the sustainability index and detect the factors influencing the spatial heterogeneity. The results show that (1) the innovation environment and economic growth are the core factors influencing the sustainable development level. (2) The sustainable development level of the cities within the urban agglomerations varies considerably. The sustainability level of central cities and provincial capital cities is significantly higher than that of outlying cities. (3) From the perspective of time, the sustainable development level of the Chengdu–Chongqing urban agglomeration and Guanzhong Plain urban agglomeration shows a rising trend; the Lanzhou–Xining urban agglomeration fluctuates greatly; and the Hohhot–Baotou–Ordos–Yulin urban agglomeration is decreasing. (4) The spatial heterogeneity level of sustainable development among cities in the western urban agglomerations is high, economic factors play a leading role in the spatial heterogeneity of sustainable development, and the western region needs to emphasize regional coordinated development.
Paradoxes in psychology resonating in its empirical research of religion
Authors: Belzen Jacob A. 
Published: February 2021

AbstractAs a scientific enterprise, the psychology of religion is vitally dependent on developments in psychology in general, sharing its strengths as well as its weaknesses. The article discusses psychology being haunted by a number of paradoxes that resonate in psychological research on religion as well. As a prominent specimen of such empirical psychology of religion, the oeuvre of R. W. Hood, a well-known contemporary US contributor to that field, is selected. Another stage in a long-standing cheerful dialogue with Hood, the article points out some remarkable parallels with the oeuvres of Hall and James, founding fathers of US psychology. While critically engaging with some of the core issues and tendencies in Hood’s publications, the article explains the sense in which his struggle to find a balance with regard to three paradoxical tendencies will be a major task for the field during the next few decades of the 21st century.
Poverty, Irrationality, and the Value of Cash Transfers
Authors: Acland Daniel 
Published: February 2021

AbstractIt has been demonstrated that irrationality reduces the efficiency of individuals’ allocations, as measured by their “true” or rational preferences. There is also evidence that poverty increases irrationality of different sorts. As a result, the net benefit to society of a cash transfer from taxpayers to welfare recipients may not be zero. The fact that the transfer will be allocated less efficiently by the recipients than by the taxpayers will reduce the value of the transfer, while if the transfer increases recipients’ rationality, it will increase the efficiency of the allocation of their pretransfer budgets, thus increasing the value of the transfer. The net effect on society will be positive or negative, depending in large part on the degree to which the transfer increases rationality. I model these effects in the context of present-biased preferences and explore the effect of irrationality, income, and the size of transfer on the value of transfers. I conclude that under a plausible range of conditions, transfers can generate a substantial positive net benefit. I also model the choices of a fully rational paternalist and find little support for paternalistic in-kind transfers.
The effect of Y on the microstructure and mechanical performance of an Mg-Al-Y casting alloy
Authors: Korgiopoulos K. , Pekguleryuz M. 
Published: February 2021

Abstract
Environmental gains of electric cars can be optimized with the use of lightweight and recyclable magnesium in the vehicle’s structural components. Ductility improvement of low-density Mg-Al alloys will extend their use in automotive body applications. The authors achieved 63% ductility improvement in Mg-6wt%Al with trace Y (1.5 ppm) due to the β-phase refinement and predicted that higher levels would not perform as well. As predicted, 0.3wt% of Y addition investigated in this study led to lower mechanical performance and β-phase refinement than those obtained with trace additions. The tensile ductility and yield strength increased by ~13% and 16%, respectively, and the compression strain to fracture by ~22%. Scanning electron and optical microscopy, X-Rays diffraction, mechanical testing and thermodynamic calculations were used to investigate the effect of 0.3wt% Y on the microstructure of Mg-6wt%Al. The matrix dissolution revealed the close association of the Al2Y and the β-Mg17Al12 phases.
Medium-scale commercial agriculture in Zimbabwe: the experience of A2 resettlement farms
Authors: Shonhe Toendepi , Scoones Ian , Murimbarimba Felix 
Published: February 2021

ABSTRACTThe emergence of medium-scale farms is having important consequences for agricultural commercialisation across Africa. This article examines the role of medium-scale A2 farms allocated following Zimbabwe's land reform after 2000. While the existing literature focuses on changing farm size distributions, this article investigates processes of social differentiation across medium-scale farms, based on qualitative-quantitative studies in two contrasting sites (Mvurwi and Masvingo-Gutu). Diverse processes of accumulation are identified across commercial, aspiring and struggling farmers, and linked to contrasting patterns of agricultural production and sale, asset ownership, employment and finance. The ability to mobilise finance, influenced by the state of the macro-economy, as well as forms of political patronage, is identified as a crucial driver. Contrary to assertions that A2 farms are largely occupied by ‘cronies’ and that they are unproductive and under-utilised, a more differentiated picture emerges, with important implications for policy and the wider politics of Zimbabwe's countryside following land reform.
Time for practice: implications of undergraduate pianists’ choices of repertoire
Authors: Zhukov Katie , Ginsborg Jane 
Published: February 2021

AbstractThere is an on-going debate as to the skills needed for 21stcentury careers in classical music and how undergraduate students should learn them. Many graduate pianists report being under-prepared for the music profession, lacking sight-reading skills in particular. While research-evidenced pedagogy for improving sight-reading skills has been developed, little is known regarding what impact enhancing this skill could have on undergraduate educational experience. The present study aimed to evaluate the effect of sight-reading training on undergraduate pianists’ choices of repertoire for practice. Two groups of 12 participants were recruited from three institutions in the UK and Australia. One group undertook the sight-reading training programme for 10 weeks. Both groups listed the solo, concerto, chamber and accompanying repertoire they practised. The mean lengths of time participants spent practising each kind of repertoire were calculated. There were significant effects of institution and therefore country on practice time but no effects of the sight-reading training. Nevertheless, the findings suggest that interventions should be designed to develop pianists’ practical skills, including sight-reading, and the long-term effects of such interventions on quality of deliberate practice, particularly on the types of repertoire that are likely to be most valuable for pianists in the early stages of their career, should be evaluated.
Challenge of forecasting demand of medical resources and supplies during a pandemic: A comparative evaluation of three surge calculators for COVID-19

AbstractEver since the World Health Organization (WHO) declared the new coronavirus disease 2019 (COVID-19) as a pandemic, there has been a public health debate concerning medical resources and supplies including hospital beds, intensive care units (ICU), ventilators and protective personal equipment (PPE). Forecasting COVID-19 dissemination has played a key role in informing healthcare professionals and governments on how to manage overburdened healthcare systems. However, forecasting during the pandemic remained challenging and sometimes highly controversial. Here, we highlight this challenge by performing a comparative evaluation for the estimations obtained from three COVID-19 surge calculators under different social distancing approaches, taking Lebanon as a case study. Despite discrepancies in estimations, the three surge calculators used herein agree that there will be a relative shortage in the capacity of medical resources and a significant surge in PPE demand if the social distancing policy is removed. Our results underscore the importance of implementing containment interventions including social distancing in alleviating the demand for medical care during the COVID-19 pandemic in the absence of any medication or vaccine. The paper also highlights the value of employing several models in surge planning.
The Data Comparison of Electron Density Between CSES and DEMETER Satellite, Swarm Constellation and IRI Model

Published: February 2021

AbstractThe China Seismo‐Electromagnetic Satellite (CSES), which is also called ZhangHeng‐1 (ZH‐1), was successfully launched on February 2, 2018. Evaluating the quality of observation data is imperative for the satellite mission and users. Through the comparative analysis of electron density between CSES and DEMETER satellite, Swarm constellation and international reference ionosphere (IRI) model from May 8, 2018 to December 31, 2019, it was found that the patterns of electron density for CSES are similar with those of other observations and model outputs, such as the maxima and minima nearly locating in the same place, having the ionospheric phenomena of wave number 3/4, electron density enhancements at mid‐latitude, and Weddell Sea Anomaly (WSA). The correlation coefficients are higher in the Southern Hemisphere, especially in the region of WSA. The correlation between CSES and IRI model is also better around the equatorial ionization anomaly crests during the daytime, while the correlation coefficients are low around the magnetic equator for the Ne single peak detected by CSES. Comparing the observation data in orbit during the same time, the correlation coefficients between CSES and Swarm constellation all exceed 0.75, the curves of nearby orbits exhibiting the consistent peaks or troughs around the roughly same latitudes. Nevertheless, there are systematic biases in the values between the electron density data of CSES and other observations/models, 1–2 times and over two times lower than IRI model during the nighttime and daytime, respectively. The electron density values of Swarm constellation are 3–6 times greater than those of CSES according to the data statistics of nearby orbits. We considered that both hardware design and data processing may potentially have effects on the Ne systematic biases between the CSES and other observations. Through the comparative analysis, it is concluded that the electron density observed by CSES can exhibit the ionospheric characteristics at the altitude of 507 km, and the data can be applied to the ionospheric phenomena study.
Reconstructing the Preindustrial Coastal Carbon Cycle Through a Global Ocean Circulation Model: Was the Global Continental Shelf Already Both Autotrophic and a CO2 Sink?
Authors: Lacroix Fabrice , Ilyina Tatiana , Laruelle Goulven G. , Regnier Pierre 
Published: February 2021

AbstractThe contribution of continental shelves to the marine carbon cycle is still poorly understood. Their preindustrial state is, for one, essentially unknown, which strongly limits the quantitative assessment of their anthropogenic perturbation. To date, approaches developed to investigate and quantify carbon fluxes on continental shelves have strongly simplified their physical and biogeochemical features. In this study, we enhance the global ocean biogeochemistry model HAMburg Ocean Carbon Cycle by explicitly representing riverine loads of carbon and nutrients, as well as improving the representation of organic matter dynamics in the coastal ocean. Our simulations, at a resolution of ∼0.4°, reveal a globally averaged shelf water residence time (RT) of 12–17 months, which is much shorter than the global RTs previously assumed in benchmark studies (>4 years). This shorter global RT, induced primarily through outer shelf regions with large oceanic inflows, promotes an efficient offshore transport of terrestrial and marine organic carbon (0.44 PgCyr−1) and a dissolved inorganic carbon sink from the organic cycling of carbon on the global shelf (net ecosystem productivity [NEP] equal to +0.20 PgCyr−1). In turn, this autotrophic state of continental shelves contributes to a weak global preindustrial sink of atmospheric CO2 (0.04 PgCyr−1), dominated by extensive regions with large oceanic inflows and positive NEPs, such as the Patagonian shelf, the East China Sea and the outer North Sea. The contemporary global shelf CO2 uptake of 0.15 PgCyr−1 furthermoresuggests that the anthropogenic CO2 uptake (0.11 PgCyr−1) on the global continental shelf is less efficient with respect to the open ocean.
Two‐Dimensional Quantitative Comparison of Density Distributions in Detrital Geochronology and Geochemistry
Authors: Sundell K. E. , Saylor J. E. 
Published: February 2021

AbstractDetrital geochronology provides insight into a broad range of Earth Science questions. However, detrital zircon U‐Pb age distributions are inherently univariate, and thus quantitative comparison methods are limited to one‐dimension (1D) and subject to nonunique results due to overlapping age groups. We developed two‐dimensional (2D) quantitative comparison measures for bivariate kernel density estimates (KDEs) and cumulative distribution functions (CDFs). These methods are extensions of 1D quantitative comparison measures commonly used in detrital geochronology: Similarity, Likeness, and Cross‐correlation of KDEs and Kolmogorov‐Smirnov (K‐S) and Kuiper tests of CDFs. We demonstrate the efficacy of these methods by applying them to a global compilation of detrital and igneous zircon univariate U‐Pb data (n = 767,660) and bivariate U‐Pb and Hf (i.e., εHfT) data (n = 114,311) parsed geographically into eight continental landmasses demarcated by Paleozoic sutures. The 2D quantitative comparison measures behave in a similar fashion to their 1D counterparts in terms of sensitivity and consistency regardless of parameterization (e.g., kernel bandwidth and discretization interval). Results show that the detrital record reliably reflects the igneous record for both univariate U‐Pb and bivariate εHfT distributions between 4,400 and 0 Ma. In contrast, 1D and 2D quantitative comparison results differ over the narrower Ediacaran‐Cambrian time interval due to nonunique univariate zircon U‐Pb age groups; the 2D quantitative results consistently identify continental landmasses involved in the formation of Gondwana. We implemented the 2D methods in a new MATLAB‐based graphical user interface, DZstats2D, which is available as open‐source code and as standalone applications for macOS and Windows.
Atmospheric Transport of North African Dust‐Bearing Supermicron Freshwater Diatoms to South America: Implications for Iron Transport to the Equatorial North Atlantic Ocean

Published: February 2021

AbstractThe equatorial North Atlantic Ocean (NAO) is a nutrient‐limited ecosystem that relies on the deposition of long‐range transported iron (Fe)‐containing aerosols to stimulate primary productivity. Using microscopy, we characterized supermicron and supercoarse mode African aerosols transported to the western NAO in boreal winter/spring. We detected three particle types including African dust, primary biological aerosol particles, and freshwater diatoms (FDs). FDs contained 4% Fe by weight due to surficial dust inclusions that may be susceptible to chemical processing and dissolution. FDs were typically larger than dust particles and comprised 38% of particles between 10 and 18 μm in diameter. The low density, high surface‐area‐to‐volume ratio, and large aspect ratios of FD particles suggest a mechanism by which they can be carried great distances aloft. These same properties likely increase the residence time of FDs in surface waters thereby increasing the time for Fe dissolution and their potential impact on marine biogeochemical cycles.
Dry Spells, Wet Days, and Their Trends Across Southern Africa During the Summer Rainy Season

Published: February 2021

AbstractDry spell frequency and wet day occurrence during the summer rainy season across southern Africa are examined using daily rainfall for 1982–2019. Evidence shows two sharp gradients in dry spell frequency, extending southeast from southern Angola to the African south coast near the westernmost boundary of preferred cloud band occurrences (diagonal gradient), and west from the Limpopo River Valley along 22–24°S (meridional gradient) (along 14–16°S in early summer) related to regional topography. Trend analysis suggests that the diagonal gradient has weakened during 1982–2019 along with some other large areas in southern Africa whereas this is only true for part of the meridional gradient. Contrastingly, wet days and Normalized Difference Vegetation Index have significantly increased in several important agricultural areas in southern Africa. Evidence suggests these changes are related to those in the midlevel Botswana High, El Niño Southern Oscillation, Southern Annular Mode, and subtropical Indian Ocean dipole.
Improving Surface Soil Moisture Estimates in Humid Regions by an Enhanced Remote Sensing Technique

Published: February 2021

AbstractUsing optical remote sensing data to downscale microwave soil moisture is currently a crucial technique for producing fine‐resolution soil moisture data set at large scales. Conventional soil moisture downscaling models are mainly developed and evaluated in arid or semi‐arid regions, but have serious limitation in humid regions. To improve soil moisture estimates under a wide range of climate regimes, this study developed a nonlinear enhanced soil moisture downscaling model and evaluated it at a typical microwave resolution over the contiguous China. The enhanced model clearly outperforms the conventional approach in estimating surface soil moisture by reducing the Root Mean Square Error (RMSE) from 0.175 vol/vol to 0.075 vol/vol under wet climate. Finally, soil moisture downscaling is conducted by applying such models (built at the 25‐km scale) at a finer (1‐km) resolution. Validation result of downscaled soil moisture against in situ data set demonstrates the advantage of the enhanced model.
Energetic Electron Precipitation Observed by FIREBIRD‐II Potentially Driven by EMIC Waves: Location, Extent, and Energy Range From a Multievent Analysis

Published: February 2021

AbstractWe evaluate the location, extent, and energy range of electron precipitation driven by ElectroMagnetic Ion Cyclotron (EMIC) waves using coordinated multisatellite observations from near‐equatorial and Low‐Earth‐Orbit (LEO) missions. Electron precipitation was analyzed using the Focused Investigations of Relativistic Electron Burst Intensity, Range and Dynamics (FIREBIRD‐II) CubeSats, in conjunction either with typical EMIC‐driven precipitation signatures observed by Polar Orbiting Environmental Satellites (POES) or with in situ EMIC wave observations from Van Allen Probes. The multievent analysis shows that electron precipitation occurred in a broad region near dusk (16–23 MLT), mostly confined to 3.5–7.5 L‐shells. Each precipitation event occurred on localized radial scales, on average ∼0.3 L. Most importantly, FIREBIRD‐II recorded electron precipitation from ∼200 to 300 keV to the expected ∼MeV energies for most cases, suggesting that EMIC waves can efficiently scatter a wide energy range of electrons.
