Physical activity always benefits employees, right? Examining the role of physical activity type, grit, stress, and career satisfaction
Authors: Flinchbaugh Carol , Zhou Qin , Zare Mortaza 
Published: April 2022

AbstractThis study tests whether employee participation in different types of physical activity benefits employees' training stress and career satisfaction perceptions differently and if grit, as a psychological resource, mediates this relationship. In two samples, we assess whether (1) regular physical activity; or (2) exercise to reach a competitive goal have similar associations with employee outcomes. In study 1, we find no relationship between employee engagement in regular physical activity and the outcomes. Moreover, grit's consistency of effort mediates the physical activity – training stress relationship, exacerbating employees' training stress. In study 2, employee exercise reduces career satisfaction and increases training stress. Importantly, grit's perseverance dimension increases their career satisfaction, and the consistency of interest dimension lessens training stress. Thus, we find evidence that employee participation in different types of physical activity leads to divergent outcomes, and that grit as a mediator only benefits employees exercising for a competitive goal.

AbstractAn end of summer snowline (EOSS) photographic dataset for Aotearoa New Zealand contains over four decades of equilibrium line altitude (ELA) observations for more than 50 index glaciers. This dataset provides an opportunity to create a climatological ELA reference series that has several applications. Our work screened out EOSS sites that had low temporal coverage and also removed limited observations when the official survey did not take place. Snowline data from 41 of 50 glaciers in the EOSS dataset were retained and included in a normalised master snowline series that spans 1977–2020. Application of the regionally representative normalised master snowline series in monthly and seasonally resolved climate response function analyses showed consistently strong relationships with austral warm-season temperatures for land-based stations west of the Southern Alps and the central Tasman Sea. There is a trend towards higher regional snowlines since the 1990s that has been steepening in recent decades. If contemporary decadal normalised master snowline series trends are maintained, the average Southern Alps snowline elevation will be displaced at least 200 m higher than normal by the 2025–2034 decade. More frequent extremely high snowlines are expected to drive more extreme cumulative mass-balance losses that will reduce the glacierised area of Aotearoa New Zealand.

AbstractAcritarch biostratigraphic and δ13C chemostratigraphic data from the Krol A Formation in the Solan area (Lesser Himalaya, northern India) are integrated to aid inter-basinal correlation of early–middle Ediacaran strata. We identified a prominent negative δ13C excursion (likely equivalent to EN2 in the lower Doushantuo Formation in the Yangtze Gorges area of South China), over a dozen species of acanthomorphs (including two new species—Cavaspina tiwariae Xiao n. sp., Dictyotidium grazhdankinii Xiao n. sp.), and numerous other microfossils from an interval in the Krol A Formation. Most microfossil taxa from the Krol A and the underlying Infra-Krol formations are also present in the Doushantuo Formation. Infra-Krol acanthomorphs support a correlation with the earliest Doushantuo biozone: the Appendisphaera grandis-Weissiella grandistella-Tianzhushania spinosa Assemblage Zone. Krol A microfossils indicate a correlation with the second or (more likely, when δ13C data are considered) the third biozone in the lower Doushantuo Formation (i.e., the Tanarium tuberosum-Schizofusa zangwenlongii or Tanarium conoideum-Cavaspina basiconica Assemblage Zone). The association of acanthomorphs with EN2 in the Krol Formation fills a critical gap in South China where chert nodules, and thus acanthomorphs, are rare in the EN2 interval. Like many other Ediacaran acanthomorphs assemblages, Krol A and Doushantuo acanthomorphs are distributed in low paleolatitudes, and they may represent a distinct paleobiogeographic province in east Gondwana. The Indian data affirm the stratigraphic significance of acanthomorphs and δ13C, clarify key issues of lower Ediacaran bio- and chemostratigraphic correlation, and strengthen the basis for the study of Ediacaran eukaryote evolution and paleobiogeography.UUID: http://zoobank.org/5289fdb2-0e49-4b3b-880f-f5b21acab371.
Interspecies cosmopolitanism: Non-human power and the grounds of world order in the Anthropocene
Authors: Burke Anthony 
Published: April 2022

AbstractCosmopolitanism claims to be the most just and inclusive of mainstream approaches to the ethics and practice of world order, given its commitment to human interconnection, peace, equality, diversity, and rights, and its concern with the many globalised pathologies that entrench injustice and vulnerability across borders. Yet it has largely remained oblivious to the agency, power, and value of non-human life on a turbulent and active Earth. Without rejecting its commitments to justice for human beings, the article challenges its humanism as both morally and politically inadequate to the situation of the Anthropocene, exemplified by the simultaneous crises of climate change, mass extinction, and the COVID-19 pandemic. In answer, the article develops new grounds and principles for an interspecies cosmopolitanism, exploring how we can reimagine its ontological foundations by creating new grounding images of subjectivity, existential unity, institutional organisation, and ordering purpose. These, in turn, can support political and institutional projects to secure the rights of ecosystems and people to flourish and persist through an increasingly chaotic epoch of human dominance and multispecies vulnerability across the Anthropocene Earth.
The power of women: Does increasing women’s parliamentary representation reduce intake of sugar-sweetened beverages among children and adolescents?
Authors: Lin Yu-Chun , Yan Huang-Ting 
Published: April 2022

AbstractObjective:Consumption of sugar-sweetened beverages (SSB) is associated with overweight and obesity in children and adolescents. Although existing research confirms the significance of economic and social factors as determinants of SSB intake, comparative studies on political factors and cross-national analyses are lacking. Research indicates that including women in the process of political decision-making promotes healthcare and child protection. This study examined how women’s parliamentary representation influences children’s and adolescents’ SSB intake compared with adults.Design:The study used cross-national food and beverage intake data from the Global Dietary Database. The outcome measurement was SSB consumption (g/day) for different population groups. We modelled SSB intake as a function of age groups, women’s parliamentary representation at the national level (the independent variable), regime types (the contextual factor) and import tariffs on SSB (the mediator) using country and time-fixed effects regression models.Setting:One-hundred eighty-five countries across three waves from 2005 to 2015.Participants:Different population groups.Results:The impact of female representation on reducing SSB consumption is more prevalent in children and adolescents than in adults. Furthermore, the effect of women’s parliamentary representation on SSB consumption among children and adolescents is conditional on a country’s democratic status. Finally, the marginal effect decreases when import tariffs on SSB are considered a link in a causal chain. No changes in adult SSB intake are statistically significant.Conclusions:The findings suggest that the presence of women in the legislature can have a substantial impact on child and adolescent health.
Lemma navigation by excellent secondary school students of Ancient Greek
Authors: Bartelds Daniël 
Published: April 2022

AbstractUnder the high cognitive pressure of a translation task, secondary school Classics students often make dictionary mistakes. Research indicates that successful students use a lemma's meta-information to engage in a feedback loop between text and dictionary. Using eye-tracking data of expert learners, this study examined how successful students employ the different types of lemma information while limiting their cognitive load. We found that students primarily manage their cognitive load by using boldface definitions as stepping-stones, but navigate through meta-information when it (1) can effectively reduce the amount of definitions and (2) refers to (morphological) features directly visible in the text. Alternatively, they use meta-information as a backup plan, when they are stuck or want to confirm a hypothesis.
Low Dissipation of Earthquake Energy Where a Fault Follows Pre‐Existing Weaknesses: Field and Microstructural Observations of Malawi’s Bilila‐Mtakataka Fault

Published: April 2022

AbstractDuring earthquakes on low (<1–2 km) displacement faults in isotropic crust, more earthquake energy is consumed by fracturing and gouge formation than in ruptures along more mature faults. To investigate how pre‐existing weaknesses affect earthquake energy dissipation along low displacement faults, we studied fault rocks from the 110 km long, 0.4–1.2 km displacement, Bilila‐Mtakataka Fault (BMF), Malawi. Where the BMF is parallel to surface metamorphic fabrics, macroscale fractures define a narrow (5–20 m wide) damage zone relative to where the BMF is foliation‐oblique (20–80 m), and to faults with comparable displacement in isotropic crust (∼40–120 m). Enhanced microfracturing and widespread gouge formation, typically reported from comparable‐displacement faults, are not observed. Therefore, minimal evidence for earthquake energy dissipation into the BMF’s surrounding wall rock exists, despite geomorphic evidence for MW 7.5–8 earthquakes. We attribute this finding to differences in earthquake energy partitioning along incipient faults in isotropic and anisotropic crust.
Observation‐Based Estimates of Eulerian‐Mean Boundary Downwelling in the Western Subpolar North Atlantic

Published: April 2022

AbstractA significant fraction of the Eulerian‐mean downwelling feeding the lower limb of the Atlantic Meridional Overturning Circulation (AMOC) occurs along the subpolar North Atlantic continental slopes and is maintained by along‐boundary densification and large‐scale geostrophic balance. We here use Argo and shipboard hydrography data to map the 2002–2015 long‐term mean density field along the boundary via a dedicated optimal interpolation tool. The overall downstream densification implies an Eulerian‐mean downwelling of 2.12 ± 0.43 Sv at 1100 m depth between Denmark Strait and Flemish Cap. A clear regional pattern emerges with downwelling in the Irminger Sea and western Labrador Sea and upwelling along Greenland western continental slope. Comparisons with independent cross‐basin estimates confirm that vertical overturning transport across the marginal seas of the subpolar North Atlantic mainly occurs along the continental slopes, and suggest the usefulness of hydrographic data in providing quantitative information about the sinking branch of the AMOC.

Published: April 2022

AbstractIntense sunward (westward) plasma flows, named Subauroral Polarization Stream (SAPS), have been known to occur equatorward of the electron auroras for decades, yet their effect on the upper thermosphere has not been well understood. On the one hand, the large velocity of SAPS results in large momentum exchange upon each ion‐neutral collision. On the other hand, the low plasma density associated with SAPS implies a low ion‐neutral collision frequency. We investigate the SAPS effect during non‐storm time by utilizing a Scanning Doppler Imager (SDI) for monitoring the upper thermosphere, SuperDARN radars for SAPS, all‐sky imagers and DMSP Spectrographic Imager for the auroral oval, and GPS receivers for the total electron content. Our observations suggest that SAPS at times drives substantial (>50 m/s) westward winds at subauroral latitudes in the dusk‐midnight sector, but not always. The occurrence of the westward winds varies with AE index, plasma content in the trough, and local time. The latitudinally averaged wind speed varies from 60 to 160 m/s, and is statistically 21% of the plasma. These westward winds also shift to lower latitude with increasing AE and increasing MLT. We do not observe SAPS driving poleward wind surges, neutral temperature enhancements, or acoustic‐gravity waves, likely due to the somewhat weak forcing of SAPS during the non‐storm time.
Do We Need to Consider Electrons' Kinetic Effects to Properly Model a Planetary Magnetosphere: The Case of Mercury

Published: April 2022

AbstractThe magnetosphere of Mercury is studied using an implicit full particle‐in‐cell simulation (PIC). We use a hybrid simulation where ions are full particles and electrons are considered as a fluid to start a PIC simulation where electrons are also particles and follow their distribution function. This approach allows us to estimate the changes introduced by the electron kinetic physics. We find that the overall macroscopic state of the magnetosphere of Mercury is little affected, but several physical processes are significantly modified in the full PIC simulation: the foreshock region is more active with more intense shock reformation, the Kelvin‐Helmholtz rippling effects on the nightside magnetopause are sharper, and the magnetotail current sheet becomes thinner than those predicted by the hybrid simulation. The greatest effect of the electron physics comes from the processes of particle energization. Both species, not just the electrons, are found to gain more energy when kinetic electron processes are included. The region with the most energetic plasma is found on the dusk side of the tail where magnetic flux ropes are formed due to reconnection. We find that the ion and electron energization is associated with the regions of reconnection and the development of kinetic instabilities caused by counter‐streaming electron populations. The resulting electron distributions are highly non Maxwellian, a process that neither MHD nor hybrid models can describe.
Recent Changes of Pacific Decadal Variability Shaped by Greenhouse Forcing and Internal Variability
Authors: Sun Weiyi , Wang Bin , Liu Jian , Dai Yifei 
Published: April 2022

AbstractPacific Decadal Variability (PDV) has enormous influences on North American and Eurasian climate and Pacific ecosystems. Its change under anthropogenic warming is of prodigious societal concern and scientific dispute. We show evidence that the observed PDV has amplified in the northeast Pacific horseshoe‐like region while weakened over the South Pacific and Kuroshio‐Oyashio Extension (KOE) region since the beginning of the 21st century. Congruently, under the influence of PDV, precipitation anomalies have significantly amplified globally and reversed the sign over Africa and East Asia. Analysis of the Coupled Model Intercomparison Project Phase 6 (CMIP6) historical simulations and future projections suggests that greenhouse forcing weakens the PDV in the South and northwestern Pacific and shortens its periodicity. However, the observed PDV's enhancement over the North Pacific eastern boundary is likely due to internal variability. Our findings on the PDV's response to anthropogenic forcing and internal variability shed light on the PDV's future change and decadal prediction.
Impacts of Transboundary Transport on Coastal Air Quality of South China

Published: April 2022

AbstractTransboundary transport plays an important role in air pollution formation in China. The coastal area of south China (CA‐SCHN) frequently experiences air pollution in spring and autumn, but the contribution of transboundary transport to the air quality is still not clear. Meteorological field analyses reveal that large‐scale synoptic patterns over east China in spring and autumn provide favorable situations facilitating southward transport of air pollutants originated from the North China Plain (NCP) and Yangtze River Delta (YRD). A springtime case study using the WRF‐Chem model shows that trans‐boundary transport of air pollutants from the NCP and YRD contributes to 27% and 46% of ozone (O3) and fine particulate matter (PM2.5) concentrations in the CA‐SCHN, respectively. In the autumn case, the contribution is around 11% for O3 and 24% for PM2.5. In the spring, air pollutants in the NCP and YRD are transported over seas by large‐scale synoptic systems to the South China Sea and re‐circulated by the sea breeze to the CA‐SCHN during daytime. In the autumn, the transport is driven by northerly winds over the land induced by large‐scale synoptic systems, and is also modulated by the local mountain‐valley breeze circulation. The results provide support for design and implementation of air pollutants control strategies in the CA‐SCHN.

AbstractWith the projected expansion of arid/semi‐arid regions in a warming world, precipitation enhancement activities such as cloud seeding will become increasingly popular and relied upon. Due to the inherent costs, a successful planning is crucial, which involves accurate model predictions. In this study, the usefulness of the Weather Research and Forecasting (WRF) model forecasts for guidance into seeding operations in the United Arab Emirates, where seeding activities have been conducted for more than two decades, is assessed. The WRF predictions are compared with ground‐based, satellite‐derived and radar reflectivity data, and in‐situ observations onboard the airplanes used to perform the seeding operations. WRF is found to have higher skill in simulating the observed cloud top pressure/temperature than the cloud fraction, with the model vertical velocity predictions also more skillful than those of the radar reflectivity. A stronger Arabian Heat Low (AHL) in the model leads to drier conditions which, together with a surface cold bias, limits the spatial extent and vertical depth of the simulated convective clouds. Development of convective rolls in the boundary layer is reported in both observations and simulations and their interaction with cold pools from convective clouds promote the development of secondary convection. Sensitivity to the choice of the Planetary Boundary Layer (PBL) scheme is also noticed, with the Yonsei University PBL scheme giving the best performance. When considering the two factors needed for a successful seeding operation that is, the presence of an updraft and clouds, the model‐predicted seeding regions largely match the areas where precipitation was observed. As the proposed WRF set up can be used operationally, the model forecasts will bring added value to the seeding activities in the country.
Regional Signatures of Forced North Atlantic SST Variability: A Limited Role for Aerosols and Greenhouse Gases

Published: April 2022

AbstractPrior studies that argue external forcings drive Atlantic Multidecadal Variability (AMV) use linear detrending to remove the global warming trend from North Atlantic sea surface temperatures (SSTs). The linear detrending method, however, aliases residual nonlinear, global‐scale warming, affecting the interpretation of results. Here we revisit the role of external forcing in AMV using large climate model ensembles, examining the influences of greenhouse gases (GHGs) and industrial aerosols—the two dominant 20th‐century external forcing agents—on North Atlantic SSTs separately from their respective global response. Our approach shows that GHGs have little to no influence unique to the North Atlantic, while industrial aerosols exert only modest influences as part of a broader loading over the Northern Hemisphere. We demonstrate that a prominent role for external forcings on AMV is an artifact of the linear detrending method that disappears when their global responses common to the World Ocean are correctly accounted for.

AbstractWhiting events are transient phenomena commonly occurring in hardwater lakes and manifesting as a turquoise coloration of surface waters during massive calcium carbonate precipitation. While biological and physico‐chemical drivers of carbonate precipitation are known, their relative contributions in controlling whiting events' timing and spatial extent remain poorly understood. Coupling spatially resolved data obtained for two sampling surveys using multiple analytical techniques and geochemical modeling, this study investigated the mechanisms underlying a whiting event during the early summer of 2019 in Lake Geneva. Satellite observations showed that the phenomenon started during a snowmelt period in the catchment at the Rhône River delta before spreading along the lake's northern shore and covering vast areas of its deeper basin. Authigenic calcite precipitated at the river mouth during mixing of warmer calcite super‐saturated lake surface waters with colder snowmelt‐diluted, sediment‐rich river water containing detrital carbonates as potential nucleation sites. The development of the whiting event depended upon the thermal stratification of the water column and the existence of a physically stable metalimnion, within which a river interflow transported finer particles across the lake. During transport, the whiting plume enriched in authigenic carbonates by settling of coarser detrital particles and additional precipitation likely both on the fine‐grained carbonate fraction and through biologically induced mechanisms in the superficial layers of the lake. This study provides novel mechanistic insights on the conditions controlling whiting events in lakes, highlighting a tight coupling of their dynamics with processes acting at the catchment scale.
