Resilience in development: Neighborhood context, experiences of discrimination, and children’s mental health
Authors: Okuzono Sakurako S. , Wilson Joseph , Slopen Natalie 
Published: August 2023

AbstractAn understanding of child psychopathology and resilience requires attention to the nested and interconnected systems and contexts that shape children’s experiences and health outcomes. In this study, we draw on data from the National Survey of Children’s Health, 2016 to 2021 (n = 182,375 children, ages 3– to 17 years) to examine associations between community social capital and neighborhood resources and children’s internalizing and externalizing problems, and whether these associations were moderated by experiences of racial discrimination. Study outcomes were caregiver-report of current internalizing and externalizing problems. Using logistic regression models adjusted for sociodemographic characteristics of the child and household, higher levels of community social capital were associated with a lower risk of children’s depression, anxiety, and behaviors. Notably, we observed similar associations between neighborhood resources and child mental health for depression only. In models stratified by the child’s experience of racial/ethnic discrimination, the protective benefits of community social capital were specific to those children who did not experience racial discrimination. Our results illustrate heterogeneous associations between community social capital and children’s mental health that differ based on interpersonal experiences of racial/ethnic discrimination, illustrating the importance of a multilevel framework to promote child wellbeing.
Human–environment interactions at Ta'ab Nuk Na, a submerged Maya salt works site in Belize

Published: August 2023

AbstractSea-level rise and settlement are investigated at Ta'ab Nuk Na, an ancient Maya salt works in Belize, by examining samples from wooden posts and marine sediment. The samples included Post 145 of Building B and the Nunavut beam, along with marine sediment columns cut from beside both wooden posts. The sediment columns were sampled at 2 cm intervals. Loss-on ignition confirmed the presence of organic material. Identifying the organic content involved removing nonorganic material from the sediment and sorting the organic material under magnification. This procedure established that most of the organic material was red mangrove (Rhizophora mangle). Red mangroves tolerate salt water, but under conditions of sea-level rise, the plants grow vertically to keep their leaves above water. Sediment, leaves, and detritus trapped in the prop roots form mangrove peat, which serves as a proxy for sea-level rise. AMS dating of fine red mangrove roots determined that the local sea levels rose at Ta'ab Nuk Na throughout the Late Classic period and continued into the Postclassic period. Radiocarbon dates obtained from the wood-post samples yielded Late Classic–period dates. Comparing the radiocarbon dates from the wooden posts and the sediment core samples determined that the site was abandoned before the rising seas flooded the area. Evidently, sea-level rise did not play a role in site abandonment.

AbstractTwenty-nine exotic common bean germplasms and three elite cultivars were examined for phenotypic diversity in two bean-producing environments (Kanpur and Shimla) across three winter seasons and one rainy season. The estimate of genetic variability parameters revealed that the exotic bean germplasm has enough diversity for all the evaluated features. The highest genotypic and phenotypic coefficients of variation were found in seed yield, followed by 100-seed weight, pods per plant and pod length. Furthermore, seed yield was the most heritable and genetically advanced quantitative feature, followed by 100-seed weight, pod length and pods per plant. According to a trait association study, the days to maturity of phenological traits have a strong positive correlation with the days to initial flowering and the days to 50% flowering. Pods per plant and seeds per pod most strongly influence increased grain yield. The first two principal components accounted for 63.3% of the variation and demonstrated significant diversity among exotic bean lines for the traits studied, according to the principal component analysis. According to the hierarchical clustering analysis, 29 accessions and three cultivars were divided into three groups. Cluster I contains early flowering and maturing accessions, while cluster III contains high pods per plant and an increased grain yield of germplasms. The fundamental source of phenological fluctuations in both environmental circumstances is temperature. This study found four genetically divergent and stable performance accessions, including EC932021, EC932189 (earliness), and EC931452, EC931971 (high grain yield), which may aid in the establishment of a bean breeding programme.

Abstract
While grain farming has seen a major shift toward organic production in recent years, the USA continues to lag behind with domestic demand continuing to outpace domestic supply, making the USA an all-around net importer. The Midwestern USA is poised to help remedy this imbalance; however, farmers continue to slowly transition to organic production systems. Existing literature has identified three prevalent narratives that farmers use to frame their organic transition: environmentalism, farm-family legacy and economic factors, in addition to a four and untested religiosity narrative. This study sought to better understand how these different narratives frame grain farmers’ thought processes for transitioning from conventional production systems to certified organic production systems. We co-created narratives around organic production with farmers, which resulted in four passages aligned with the literature: farm-family legacy, economic values, environmental values and Christianity and stewarding Eden. Then, we mailed a paper survey to conventional, in transition and certified organic Indiana grain farmers in order to test how these different narratives motivated organic production. We found that the most prevalent narrative around organic production is the farm-family legacy, which specifically resonated with midsize farmers. We also found that the religious stewardship narrative resonated with a substantial number of organic and mixed practice farmers, which is likely due to Amish farmers within the sample. These results shed light on the role that narratives and associated values play in organic practice use and can inform the organic efforts of agricultural professionals.
When do voters perceive intra-party conflict? A democratic life cycle perspective
Authors: Klingelhöfer Tristan , Müller Jochen 
Published: August 2023

AbstractPolitical parties commonly experience internal disagreements. Recently, evidence is accumulating that outright internal discord makes a party much less attractive to voters. However, we do not understand well when citizens perceive a party to be internally conflicted in the first place. We here explain citizens’ perceptions from a democratic life cycle perspective: Factors related to the periodic conduct of elections induce higher levels of intra-party conflict and make it more visible to citizens. To test this argument, we combine survey data on citizens’ perceptions of political parties in Germany spanning 16 years with indicators moderating (the visibility of) intra-party conflict. The analysis shows that citizens perceive more internal conflict when parties are heterogenous, when they are governing, when election day is distant, and when electoral losses accumulate. This demonstrates the recurring patterns in citizens’ perceptions of political parties and suggests self-reinforcing dynamics between citizen assessments and election outcomes.
Teaching Latin and ancient Greek in the 21st-century Primary School: Framing local approaches to international challenges
Authors: Bracke Evelien 
Published: August 2023

AbstractThe idea for this special issue of Journal of Classics Teaching arose from the conference ‘Monsters in the classroom: Latin and Greek at primary school’ which Steve Hunt (Cambridge), Lidewij Van Gils (Amsterdam), and myself (Ghent) co-organised in January of 2022.1 This conference gathered teaching expertise from eight countries and attracted more than 120 participants from 20 countries to discuss both the successes and challenges related to current international practice in the teaching of Classical languages at primary school. It became a constructive and fruitful event, where participants from different countries shared good practice in order to learn from each other and formulate steps forward.
Designing Vocabulous: a Case Study in Classics, EdTech and English Literacy
Authors: Huelin Lucy 
Published: August 2023

AbstractThis article examines the website Vocabulous, an innovative resource that combines Classics and English literacy. The aim of Vocabulous is to improve students' English vocabulary knowledge and skills using Latin and Greek root patterns. For example, the root ‘scrip’ meaning ‘write’ can help students understand that ‘inscription’, ‘manuscript’ and ‘transcription’ are all related to writing. Students use these roots to work out the meaning of unfamiliar vocabulary, so that by the end of the programme, they have the skills they need to decipher new words on their own. As Alex Quigley notes, ‘over 90% of the vocabulary of academic texts in school has Latin and Greek origins and therefore teaching etymology has positive implications for learning and cracking the academic code of school’ (Quigley, 2018: 71). This article discusses the pedagogy behind the site, the selection of Latin and Greek roots, the design of the questions (based on vocabulary acquisition research) and the use of animated videos to engage students. The article concludes by outlining the current Vocabulous trial with 10–13-year-olds in 50 schools across the UK, combining teacher testimonies with ideas for practical application in the classroom1. Vocabulous is funded by The SHINE Trust and is part of a research trial led by Professor Arlene Holmes-Henderson and Christ Church, Oxford. It will be available for school subscriptions from September 2023.
Simulation of Ground Motion From Finite‐Fault Modeling Incorporating the Influence of Duration

Published: August 2023

AbstractOn 21 May 2021 (local time), an Mw 6.1 earthquake struck the Yangbi County, Yunnan Province, China. The finite fault stochastic simulation approach is usually used to simulate ground motions in high‐frequency band (f > 1 Hz). Model parameters needed for earthquake ground motion simulation mainly include source, path, and site. In the high‐frequency ground motion simulation program widely used in earthquake engineering, the reciprocal of corner frequency is typically used to define the source rise time; however, the complete step‐wise derivation process is unavailable. In deriving the static corner frequency f0, source rise time is typically estimated to be the time required for the rupture to reach 50% of the final location, and the source rise time then can be obtained as 0.27/f0, which is consistent with the hypothesis of corner frequency and rupture velocity, and the correlation and integrity between parameters are established. This study also focuses on the influence of different source rise times and path durations on the simulation results, such as Fourier acceleration spectrum, pseudo‐spectral acceleration, and peak ground acceleration. The results show that the source rise time recommended in this simulation can improve the accuracy of near‐fault ground motion simulations. This study provides suggestions for a reasonable selection of path duration in different engineering applications.

AbstractThe gravitational sinking of organic debris from ocean ecosystems is a dominant mechanism of the biological carbon pump (BCP) that regulates the global climate. The fraction of primary production exported downward, the e‐ratio, is an important but poorly constrained BCP metric. In mid‐ and high‐latitude oceans, seasonal and local variations of sinking particle fluxes strongly modulate the e‐ratio. These locally specific e‐ratio variations and their ecological foundations are here encapsulated in the term “export systems” (ES). ES have been partly characterized for a few ocean locations but remain largely ignored over most of the ocean surface. Here, in a fully conceptual approach and with the primary aim to understand rather than to estimate ocean carbon export, we combine biogeochemical (BGC) modeling with satellite observations to map ES at fine spatio‐temporal scales. We identify four plausible ES with distinct e‐ratio seasonalities across mid‐ and high‐latitude oceans. The ES map confirms the outlines of traditional BGC provinces and unveils new boundaries indicating where (and how) the annual relationship between carbon export and production changes markedly. At six sites where ES features can be partially inferred from in situ data, we test our approach and propose key ecological processes driving carbon export. In the light of our findings, a re‐examination of 1,841 field‐based e‐ratios could challenge the conventional wisdom that e‐ratios change strongly with latitude, suggesting a possible seasonal artifact caused by the timing of observations. By deciphering carbon export mechanistically, our conceptual ES map provides timely directions to emergent ocean robotic explorations of the BCP.
Gulf Stream Sea Surface Temperature Anomalies Associated With the Extratropical Transition of North Atlantic Tropical Cyclones

Published: August 2023

AbstractThis study investigates Gulf Stream (GS) sea surface temperature (SST) anomalies associated with the extratropical transition (ET) of tropical cyclones (TCs) in the North Atlantic. Composites of western North Atlantic TCs indicate that GS SSTs are warmer, and both large‐ and fine‐scale SST gradients are weaker than average, for TCs that begin the ET process but do not complete it, compared with TCs that do. Further analysis suggests that the associated fine‐scale GS SST gradient anomalies are related to atmospheric processes but not the same as those that are typically associated with the onset of ET. As sensible heat flux gradients and surface diabatic frontogenesis are shown to generally scale with the local SST gradient strength, these results suggest that knowledge of the fine‐scale GS SST gradient in the weeks prior to the arrival of a TC might potentially provide additional information regarding the likelihood of that system completing ET.
Snow Cover on the Tibetan Plateau and Lake Baikal Intensifies the Winter North Atlantic Oscillation

Published: August 2023

AbstractThis paper revealed a physical connection between the antiphase variation in the preceding autumn Tibetan Plateau (TP) and Lake Baikal snow cover anomalies (TBSA) and the following winter North Atlantic Oscillation (NAO) on interannual time scales during 1979–2021. The antiphase variation in TBSA, accounting for 44% of the total years, has a dipole structure in autumn, which prolonged into the following winter. The persistent antiphase TBSA associated diabatic forcing, disturbances and transient eddies favor a double wave train structure spanning the TP (east of Baikal) and North Atlantic from autumn to winter. Amid the wave train, the circulation anomalies over the North Atlantic extract more energy from the basic flow due to the seasonal increase in the westerly jet, which further evolves into the winter NAO pattern. Our results provide new insights into the formation and projection of winter NAO from the perspective of subtropical and extratropical Eurasia snow.

AbstractShallow cloud decks residing in or near the boundary layer cover a large fraction of the Southern Ocean (SO) and play a major role in determining the amount of shortwave radiation reflected back to space from this region. In this article, we examine the macrophysical characteristics and thermodynamic phase of low clouds (tops <3 km) and precipitation using ground‐based ceilometer, depolarization lidar and vertically‐pointing W‐band radar measurements collected during the Macquarie Island Cloud and Radiation Experiment (MICRE) from April 2016 to March 2017. During MICRE, low clouds occurred ∼65% of the time on average (slightly more often in austral winter than summer). About 2/3 of low clouds were cold‐topped (temperatures ≤0°C). These were thicker and had higher bases on average than warm‐topped clouds. 83%–88% of cold‐topped low clouds were liquid phase at cloud base (depending on the season). The majority of low clouds had precipitation in the vertical range 150–250 m below cloud base, a significant fraction of which did not reach the surface. Phase characterization is limited to the period between April 2016 and November 2016. Small‐particle (low‐radar‐reflectivity) precipitation (which dominates precipitation occurrence) was mostly liquid below‐cloud, while large‐particle precipitation (which dominates total accumulation) was predominantly mixed/ambiguous or ice phase. Approximately 40% of cold‐topped clouds had mixed/ambiguous or ice phase precipitation below (with predominantly liquid phase cloud droplets at cloud base). Below‐cloud precipitation with radar reflectivity factors below about −10 dBZ were predominantly liquid, while reflectivity factors above about 0 dBZ were predominantly ice.

AbstractQuantifying carbon dioxide (CO2) fluxes between soil and atmosphere is key in understanding net ecosystem C exchange and biogeochemical C cycling in plant‐soil systems. In ecosystems with low primary production and sparse vegetation, for example, dry lands or subpolar regions where C fluxes are small, measurement sensitivity is key—even so when measurements are combined with isotopic labeling. Here, we present a simplified gas sampling system developed to facilitate sampling and measurement of low soil CO2 fluxes as well as in situ 13CO2 labeling in the same setup. The capacity of the system was tested in a set of feature tests along with gas measurements of dryland soil‐biocrust systems. The system's sensitivity to capture minor changes in CO2 concentration was confirmed in respiration and photosynthesis measurements of soil‐biocrust systems, where fluxes down to 0.1 μmol CO2 m−2 s−1 were quantified. A balloon, implemented to counterbalance underpressure build‐up during gas withdrawal, mitigated 72% of pressure differences at sampling. The overall system volume was reduced to a minimum to limit contamination caused by residual air, and the design enabled one‐step flushing and evacuation of system compartments and gas sample bags, successfully ruling out cross‐contamination between samples. Ultimately, this system offers a flexible and accessible solution for CO2 measurements that can be applied not only on arid soils with low biological activity and turnover rates, but also on plant‐soil systems. The modifications enabled larger, and thereby more representative, sample volumes to be collected while limiting incubation, contamination, and pressure effects on the intact soil system.

AbstractConverging evidence suggests that schizophrenia (SZ) with primary, enduring negative symptoms (i.e., Deficit SZ (DSZ)) represents a distinct entity within the SZ spectrum while the neurobiological underpinnings remain undetermined. In the largest dataset of DSZ and Non-Deficit (NDSZ), we conducted a meta-analysis of data from 1560 individuals (168 DSZ, 373 NDSZ, 1019 Healthy Controls (HC)) and a mega-analysis of a subsampled data from 944 individuals (115 DSZ, 254 NDSZ, 575 HC) collected across 9 worldwide research centers of the ENIGMA SZ Working Group (8 in the mega-analysis), to clarify whether they differ in terms of cortical morphology. In the meta-analysis, sites computed effect sizes for differences in cortical thickness and surface area between SZ and control groups using a harmonized pipeline. In the mega-analysis, cortical values of individuals with schizophrenia and control participants were analyzed across sites using mixed-model ANCOVAs. The meta-analysis of cortical thickness showed a converging pattern of widespread thinner cortex in fronto-parietal regions of the left hemisphere in both DSZ and NDSZ, when compared to HC. However, DSZ have more pronounced thickness abnormalities than NDSZ, mostly involving the right fronto-parietal cortices. As for surface area, NDSZ showed differences in fronto-parietal-temporo-occipital cortices as compared to HC, and in temporo-occipital cortices as compared to DSZ. Although DSZ and NDSZ show widespread overlapping regions of thinner cortex as compared to HC, cortical thinning seems to better typify DSZ, being more extensive and bilateral, while surface area alterations are more evident in NDSZ. Our findings demonstrate for the first time that DSZ and NDSZ are characterized by different neuroimaging phenotypes, supporting a nosological distinction between DSZ and NDSZ and point toward the separate disease hypothesis.
