One British Archive: The Treasures of Stonyhurst College Libraries
Authors: Reutcke Chelsea
Published: January 2024

This essay inaugurates One British Archive, a new series in the Journal of British Studies. This short essay describes the little-known archive, libraries, and museum of Stonyhurst College in England. Stonyhurst represents a continuation of the College of St Omers, a Catholic institution started in continental Europe in the sixteenth century, when Catholics were routinely prosecuted in England. This transnational quality of British expatriate communities in Europe is reflected in the collections. The modern preparatory school contains not only the records of St Omers but also the papers and books of numerous local families and school children that passed through its doors. The current archive, libraries, and museum are thus a treasure trove for anyone pursuing studies into Catholicism, book history, British education, and more.
Dynamic interaction of gravity currents in a confined porous layer
Authors: Yang Kaien , Zheng Zhong
Published: January 2024

We study the dynamic interaction of two gravity currents in a confined porous layer, one heavier and one lighter, partly inspired by the practice of geological

$\mathrm {CO}_2$

sequestration in oil fields. Two coupled nonlinear advective-diffusive equations are derived to describe the time evolution of the profile shape of both the upper (lighter) and lower (heavier) currents. At early times, the upper and lower currents remain separated and propagate independently. As time progresses, the currents approach each other and start to interact. We have identified eight different regimes of gravity current interaction at late times, impacted by four dimensionless parameters, representing the flow rate partition, ratio of buoyancy over the injection force, and the viscosity contrasts between the two injecting and displaced fluids. By defining appropriate similarity variables at either the early or late times, the governing partial differential equations (PDEs) reduce to different ordinary differential equations (ODEs), corresponding to the classic nonlinear diffusion solutions at early times and eight different self-similar solutions at late times when the currents attach to each other. It is of interest to note that in four of the eight regimes of late-time interaction (regimes 2, 6–8), self-similar solutions can be constructed by combining appropriately the three basic solutions (i.e. shock, rarefaction and travelling wave solutions) identified during single fluid injection in confined porous layers. In the four other regimes (regimes 1, 3–5), implicit solutions in the form of logarithm or error functions are obtained due to the influence of flow confinement and interaction of gravity currents. Potential implications of the model and solutions are also briefly discussed in the context of

Twin forces: similarity between rotation and stratification effects on wall turbulence
Authors: Zhang Shengqi , Sun Chao
Published: January 2024

Can the similarity between rotation and stratification provide quantitative predictions for complex turbulence? In this work, we focus on plane Couette turbulence as the background flow, which allows us to eliminate the key differences between Rayleigh–Bénard and Taylor–Couette turbulence, and facilitates a quantitative mapping across many complex turbulent systems involving rotation, stratification and curvature effects. To characterize the separated or coupled effects of rotation and stratification, we introduce an overall Richardson number

${Ri}_\chi$

which is the sum of the Coriolis Richardson number

$Ri_\theta$

and the buoyancy Richardson number

$Ri_T$

. When the Prandtl number

$Pr=1$

, the heat and inertial-frame momentum transport almost coincide and mainly depend on

${Ri}_\chi$

and the Reynolds number, regardless of the specific ratio between

$Ri_\theta$

and

$Ri_T$

. When

$Pr$

varies, the weighted average

${Nu}_\chi$

of the transport coefficients can still remain approximately invariant in most cases. Furthermore, the large-scale structures in purely rotating and purely stratified cases exhibit strikingly similar features. These findings not only indicate a more reasonable analogy for the ultimate Taylor–Couette turbulence but also pave the way for developing new predictive models for natural and industrial processes.
Capturing the edge of chaos as a spectral submanifold in pipe flows
Authors: Kaszás Bálint , Haller George
Published: January 2024

An extended turbulent state can coexist with the stable laminar state in pipe flows. We focus here on short pipes with additional discrete symmetries imposed. In this case, the boundary between the coexisting basins of attraction, often called the edge of chaos, is the stable manifold of an edge state, which is a lower-branch travelling wave solution. We show that a low-dimensional submanifold of the edge of chaos can be constructed from velocity data using the recently developed theory of spectral submanifolds (SSMs). These manifolds are the unique smoothest nonlinear continuations of non-resonant spectral subspaces of the linearized system at stationary states. Using very low-dimensional SSM-based reduced-order models, we predict transitions to turbulence or laminarization for velocity fields near the edge of chaos.
Heatwaves in summer 2022 forces substantial mass loss for Urumqi Glacier No. 1, China
Authors: Xu Chunhai , Li Huilin , Wang Feiteng , Li Zhongqin , Zhou Ping , Liu Shuangshuang
Published: January 2024

Extreme heat events in the summer of 2022 were observed in Eurasia, North America and China. Glaciers are a unique indicator of climate change, and the European Alps experienced substantial glacier mass loss as a result of the conditions in 2022, which prompted a wide range of community concerns. However, relevant findings for glaciers in China have not been currently reported. Here, we document the response of Urumqi Glacier No. 1 in the eastern Tien Shan to the extreme heat observed in 2022 based on in situ measurements that span more than 60 years. In 2022, Urumqi Glacier No. 1 exhibited the second largest annual mass loss on record, and the summer mass balance was the most negative on record. The hottest summer on record and relatively lower solid precipitation ratio contributed to the exceptional mass losses at Urumqi Glacier No. 1 in 2022, demonstrating the significant influence of heatwaves on extreme glacier melt in China.
Manner, result, and intention: implications for event typology from a cognitive account of verb semantics based on fulfilment types
Authors: Kou Xinyan , Hohenstein Jill
Published: January 2024

Verb semantics has been widely approached as a dichotomy of manner and result. However, from a cognitive perspective, manner and result are often linked by intention, as captured by the ‘fulfilment type’ property formulated in the Realisation event domain in Talmy’s event integration theory. The four ‘fulfilment types’ (intrinsic-, moot-, implied-, and attained-fulfilment) indicate different degrees of result certainty in verbs. This study investigates whether manner/result complementarity is cognitively less dichotomous and more nuanced, as the four fulfilment types in verbs could indicate more than two mental representations of verbs. Through two psycholinguistic experiments, we examine whether fulfilment types influence the cognitive salience of manner and result in novel verb meaning interpretation (Experiment 1) and the semantic relatedness between English verbs with different fulfilment types (Experiment 2). Our results demonstrate that manner and result in the mental lexicon act less like a dichotomy but more like a cline. This blur between manner and result verb statuses has consequences for a language’s typological stance in the Realisation domain and implications for how Talmyan event research should be extended beyond well-studied Motion.
Does support for redistribution mean what we think it means?
Authors: Margalit Yotam , Raviv Shir
Published: January 2024

When surveyed, clear majorities express concern about inequality and view the government as responsible for addressing it. Scholars often interpret this view as popular support for redistribution. We question this interpretation, contending that many people have little grasp of what reducing inequality actually entails, and that this disconnect masks important variation in preferences over concrete policies. Using original survey and experimental US data, we provide systematic evidence in line with these conjectures. Furthermore, when asked about more concrete redistributive measures, support for government action changes significantly and aligns more closely with people's self-interest. These findings have implications for how egalitarian policies can be effectively communicated to the public, as well as methodological implications for the study of preferences on redistribution.
Who Gets Hired? Political Patronage and Bureaucratic Favoritism
Authors: HASSAN MAI , LARREGUY HORACIO , RUSSELL STUART
Published: January 2024

Most research on biased public sector hiring highlights local politicians’ incentives to distribute government positions to partisan supporters. Other studies instead point to the role of bureaucratic managers in allocating government jobs to close contacts. We jointly consider the relative importance of each source of biased hiring as an allocation problem between managers and politicians who have different preferences regarding public sector hiring and different abilities to realize those preferences. We develop a theoretical model of each actor’s relative leverage and relative preferences for different types of public sector positions. We empirically examine our theory using the universe of payroll data in Kenyan local governments from 2004 to 2013. We find evidence of both patronage and bureaucratic favoritism, but with different types of bias concentrated in different types of government jobs, as our theory predicts. Our results highlight the inadequacy of examining political patronage alone without incorporating the preferences and leverage of the bureaucratic managers who are intricately involved in hiring processes.
Lethal effect of Goniozus legneri on Cactoblastis cactorum: A potential biocontrol agent for inundative releases
Authors: Varone Laura , Faltlhauser Ana , Fuentes Corona Malena , Garrido Silvina , Cichón Liliana , Cecere María Carla , Hight Stephen D. , Bruzzone Octavio
Published: January 2024

Cactoblastis cactorum (Berg) (Lepidoptera: Pyralidae), the cactus moth, is native to South America with a widespread distribution in Argentina. The larvae consume the interior of Opuntia spp. (Cactaceae) plants. The moth was used as a biocontrol agent against invasive non-native Opuntia spp. in many countries around the world. The cactus moth arrived unintentionally in Florida, USA, expanded its range and threatened Opuntia-based agriculture and natural ecosystems in southern North America. The insect is also a pest of cultivated O. ficus-indica L. in Argentina. An endemic South American parasitoid, Goniozus legneri Gordth (Hymenoptera: Bethylidae), is used in inundative biological control programmes against lepidopteran pests. The goal of this work was to evaluate G. legneri as a biocontrol agent to be used in inundative releases against C. cactorum. Mortality of C. cactorum by G. legneri was assessed at different spatial scales, as well as the interactions with Apanteles opuntiarum Martínez & Berta (Hymenoptera: Braconidae), a common Argentine natural enemy of C. cactorum. The ability of G. legneri to paralyse, parasitise and kill C. cactorum was confirmed. The paralysis inflicted on C. cactorum larvae reduced larval damage to the plants by 85%. Using two parasitoid species increased the mortality of C. cactorum larvae, but it was highly dependent on the order of their arrival. The combined mortality caused by both parasitoids was higher than a single one, in particular when G. legneri arrived first (56 ± 1%), suggesting asymmetric competition due to the preference of G. legneri attacking previously parasitised larvae. Goniozus legneri has potential as an inundative biocontrol agent of C. cactorum, but its interaction with the classical biocontrol agent A. opuntiarum needs to be considered.
Racial Colonists in the Nazi East: Disabled Veterans and the Malleable Boundaries of Race, Masculinity, and Disability
Authors: Goodwin Christopher Thomas
Published: January 2024

The Wehrmacht's stunning victories in the first three years of the Second World War produced a euphoric response among Nazi leaders. Suddenly, the East became a vast expanse of nearly limitless possibilities, and creating a new racial order topped the list. Although most historians have focused on the Volksdeutsche, the regime also planned to settle veterans after the war's conclusion to serve as model Germans, farmers, and a “living wall” to defend the East. As the war dragged on into 1942 and these men continued to fight, the regime turned to disabled veterans to garrison the East. The SS designed a racial selection process that proved too restrictive to generate enough applicants and, during 1943 and 1944, settlement officials revised standards. In the process, contingency, constrained practices, and contested ideology all cast the boundaries of race, gender, sexuality, able-bodiedness, and disability as much more malleable than Nazi propaganda projected.
Construction, Real Uncertainty, and Stock-Level Investment Anomalies
Authors: Aretz Kevin , Kagkadis Anastasios
Published: January 2024

We show that the negative relation between real investments and future stock returns is primarily driven by the subsample of firms building additional capacity. We develop a real options model to rationalize that evidence based on the premise that firms need to learn how to best operate modern capacity vintages, inducing idiosyncratic uncertainty in that capacity’s production costs over the learning period. Conversely, the uncertainty lowers the expected return of firms with newly built capacity until it is resolved. Further evidence based on profit sensitivities to aggregate conditions; analyst forecast-error volatilities; and high- versus low-tech industry subsamples supports our uncertainty explanation.
‘Whitefellas got miserable language skills’: Differentiation, scripted speech, and Indigenous discourses
Authors: Bednarek Monika , Meek Barbara A.
Published: January 2024

Linguistic differences in staged or scripted performances matter, since language, or language-ing, is a critical component in structuring power and maintaining unequal social differences or challenging and complicating them. To investigate such scripted speech in the context of Indigenous characters, we draw on the semiotic processes of erasure and rhematisation as well as the newly proposed concepts of erasure marking and semiotic overlay. We examine a dataset of Australian television series with Indigenous characters that feature significant creative involvement by Aboriginal and/or Torres Strait Islander individuals. Crucially, these series address mainstream, mixed audiences, meaning they must blend multiple perspectives to reach diverse viewers. We explore overt meta-discourses and subtle signs of linguistic characterisation to show how Indigenous screen creatives counter or challenge erasure and rhematisation by diversifying and complicating characters’ linguistic repertoires and bringing in Indigenous discourses and perspectives.

The World We Have Lost: Reflections on Varieties of Masculinity at Work
Authors: Strangleman Tim
Published: January 2024

The focus on gender in and around the process of deindustrialisation is a very welcome development. The academic attention paid to the decline of male dominated places of work in part can be seen as a continuation of industrial/work sociology's longstanding interest in working-class industrial workers. It may seem counterintuitive to suggest that, notwithstanding a critical gendered account of deindustrialization that pays more attention to women, there remains a need to understand more fully the subtle processes of male gender construction within industrial work. Arguably what has not been fully accounted for are the subtle, complex, and varied ways in which younger males became fully fledged men through a shopfloor ritual, social and cultural transmission, and rites of passage. The article makes two main points. Firstly, it reflects on the notion of care in work and the idea of a moral order of the workplace wherein the workplace acted as an extended caring family. I want to think about this social form through my own research as well as that of other scholars in a variety of industrial workplaces, and also by drawing on workplace autobiography. Secondly, the piece highlights the continued attraction of an older one-dimensional image of male industrial work. In studying this aspect of workplace masculinity, we might be better placed to think about the nature of gendered loss associated with mass industrial closure over time and how in-work socialization patterns have been dramatically transformed. In the process this account will add great depth to our understanding of deindustrialization and industrial culture more generally.
An observational study of parental language during play and mealtime in toddlers at variable likelihood for autism
Authors: THOMPSON Kelsey , CHOI Elizabeth , ARTIS Jonet , DUBAY Michaela , BARANEK Grace T. , WATSON Linda R.
Published: January 2024

Parental language input influences child language outcomes but may vary based on certain characteristics. This research examined how parental language differs during two contexts for toddlers at varying likelihood of autism based on their developmental skills. Parental language (quantity, quality, and pragmatic functions) was analyzed during dyadic play and mealtime interactions as a secondary data analysis of observational data from a study of toddlers at elevated and lower likelihood of autism. Child developmental skills and sensory processing were also assessed. Parents used more words per minute, directives, and verbs during play and more adjectives, descriptions, and questions during mealtime. Parental language differed based on child fine motor skills, receptive language, and levels of sensory hyporesponsiveness but not autism likelihood. Overall, this study found that parental language varies based on context and child developmental skills. Future research examining parental language should include pragmatic functions and context across developmental trajectories.
Public debt as private liquidity: the Poincaré experience (1926–1929)
Authors: Espic Aurélien
Published: January 2024

In the follow-up to the 1926 political and monetary crisis in France, a new government led by Raymond Poincaré attempted to restore monetary stability by restructuring public debt. A sinking fund was missioned to withdraw short-term public bills from money markets. This policy disorganized the largest Parisian banks of the time, as they relied on these bills to manage their liquidity. Without developed domestic money markets, no other asset could absorb the excess liquidity freed by the withdrawal of these bills, and these leading banks faced a low-rate environment. In search of yield, they expanded their activities abroad a few months before the 1929 crash. These findings renew our understanding of the expansion of France's banking sector in the 1920s. In addition, they shed new light on the role of public debt in financial stability in an open economy.
Virtually delivered guided self-help for binge eating disorder and bulimia nervosa: findings from a service evaluation

Published: January 2024

Background:

Timely intervention is beneficial to the effectiveness of eating disorder (ED) treatment, but limited capacity within ED services means that these disorders are often not treated with sufficient speed. This service evaluation extends previous research into guided self-help (GSH) for adults with bulimic spectrum EDs by assessing the feasibility, acceptability, and preliminary effectiveness of virtually delivered GSH using videoconferencing.

Method:

Patients with bulimia nervosa (BN), binge eating disorder (BED) and other specified feeding and eating disorders (OSFED) waiting for treatment in a large specialist adult ED out-patient service were offered virtually delivered GSH. The programme used an evidence-based cognitive behavioural self-help book. Individuals were supported by non-expert coaches, who delivered the eight-session programme via videoconferencing.

Results:

One hundred and thirty patients were allocated to a GSH coach between 1 September 2020 and 30 September 2022; 106 (82%) started treatment and 78 (60%) completed treatment. Amongst completers, there were large reductions in ED behaviours and attitudinal symptoms, measured by the ED-15. The largest effect sizes for change between pre- and post-treatment were seen for binge eating episode frequency (d = –0.89) and concerns around eating (d = –1.72). Patients from minoritised ethnic groups were over-represented in the non-completer group.

Conclusions:

Virtually delivered GSH is feasible, acceptable and effective in reducing ED symptoms amongst those with bulimic spectrum disorders. Implementing virtually delivered GSH reduced waiting times, offering a potential solution for long waiting times for ED treatment. Further research is needed to compare GSH to other brief therapies and investigate barriers for patients from culturally diverse groups.
Conceptualization of the term “ecological validity” in neuropsychological research on executive function assessment: a systematic review and call to action
Authors: Suchy Yana , DesRuisseaux Libby A. , Gereau Mora Michelle , Brothers Stacey Lipio , Niermeyer Madison A.
Published: January 2024

Objective:

“Ecological validity” (EV) is classically defined as test’s ability to predict real-world functioning, either alone or together with test’s similarity to real-world tasks. In neuropsychological literature on assessment of executive functions (EF), EV is conceptualized inconsistently, leading to misconceptions about the utility of tests. The goal of this systematic review was to examine how EV is conceptualized in studies of EF tests described as ecologically valid.

Method:

MEDLINE and PsychINFO Databases were searched. PRISMA guidelines were observed. After applying inclusion and exclusion criteria, this search yielded 90 articles. Deductive content analysis was employed to determine how the term EV was used.

Results:

About 1/3 of the studies conceptualized EV as the test’s ability to predict functional outcomes, 1/3 as both the ability to predict functional outcome and similarity to real-world tasks, and 1/3 were either unclear about the meaning of the term or relied on notions unrelated to classical definitions (e.g., similarity to real-world tasks alone, association with other tests, or the ability to discriminate between populations).

Conclusions:

Conceptualizations of the term EV in literature on EF assessment vary grossly, subsuming the notions of criterion, construct, and face validity, as well as sensitivity/specificity. Such inconsistency makes it difficult to interpret clinical utility of tests that are described as ecologically valid. We call on the field to require that, at minimum, the term EV be clearly defined in all publications, or replaced with more concrete terminology (e.g., criterion validity).
Diverse Sound Practices: An exploration of experimental electronic music in regional Australia
Authors: Brown Andrew R. , Bennett Andy , Ferguson John , Strong Catherine
Published: January 2024

Examining the role of arts and culture in regional Australia often focuses on economic aspects within the creative industries. However, this perspective tends to disregard the value of unconventional practices and fails to recognise the influence of regional ecological settings and the well-being advantages experienced by amateur and hobbyist musicians who explore ubiquitous methods of music creation. This article presents the results of a survey conducted among practitioners in regional Australia, exploring their utilisation of creative technology ecosystems. This project marks the first independent, evidence-based study of experimental electronic music practices in regional Australia and how local and digital resource ecosystems support those activities. Spanning the years 2021 and 2022, the study involved interviewing 11 participants from many Australian states. In this article, we share the study’s findings, outlining the diverse range of experimental electronic music practices taking place across regional Australia and how practitioners navigate the opportunities and challenges presented by their local context.
Food marketing on digital platforms: what do teens see?
Authors: Elliott Charlene D , Truman Emily
Published: January 2024

Objective:

Given the aggressive marketing of foods and beverages to teenagers on digital platforms, and the paucity of research documenting teen engagement with food marketing and its persuasive content, the objective of this study is to examine what teenagers see as teen-targeted food marketing on four popular digital platforms and to provide insight into the persuasive power of that marketing.

Design:

This is an exploratory, participatory research study, in which teenagers used a special mobile app to capture all teen-targeted food and beverage marketing they saw on digital media for 7 d. For each ad, participants identified the brand, product and specific appeals that made it teen-targeted, as well as the platform on which it was found.

Setting:

Online (digital media) with teenagers in Canada.

Participants:

Two hundred and seventy-eight teenagers, aged 13–17 years, were participated. Most participants were girls (63 %) and older teenagers (58 % aged 16–17 years).

Results:

Participants captured 1392 teen-targeted food advertisements from Instagram, Snapchat, TikTok and YouTube. The greatest number of food marketing examples came from Instagram (46 %) (with no difference across genders or age), while beverages (28·7 %), fast food (25·1 %) and candy/chocolate were the top categories advertised. When it comes to persuasive power, visual style was the top choice across all platforms and participants, with other top techniques (special offer, theme and humour), ranking differently, depending on age, gender and platform.

Conclusions:

This study provides insight into the nature of digital food marketing and its persuasive power for teenagers, highlighting considerations of selection and salience when it comes to examining food marketing and monitoring.

Published: January 2024

Objective:

The UK Soft Drinks Industry Levy (SDIL) (announced in March 2016; implemented in April 2018) aims to incentivise reformulation of soft drinks to reduce added sugar levels. The SDIL has been applauded as a policy success, and it has survived calls from parliamentarians for it to be repealed. We aimed to explore parliamentary reaction to the SDIL following its announcement until two years post-implementation in order to understand how health policy can become established and resilient to opposition.

Design:

Searches of Hansard for parliamentary debate transcripts that discussed the SDIL retrieved 186 transcripts, with 160 included after screening. Five stages of Applied Thematic Analysis were conducted: familiarisation and creation of initial codebooks; independent second coding; codebook finalisation through team consensus; final coding of the dataset to the complete codebook; and theme finalisation through team consensus.

Setting:

The United Kingdom Parliament

Participants:

N/A

Results:

Between the announcement (16/03/2016) – royal assent (26/04/2017), two themes were identified1: SDIL welcomed cross-party 2: SDIL a good start but not enough.Between royal assent – implementation (5/04/2018), one theme was identified3: The SDIL worked – what next?The final theme identified from implementation until 16/03/2020 was4: Moving on from the SDIL.

Conclusions:

After the announcement, the SDIL had cross-party support and was recognised to have encouraged reformulation prior to implementation. Lessons for governments indicate that the combination of cross-party support and a policy’s documented success in achieving its aim can help cement the resilience of it to opposition and threats of repeal.
Relationship between home garden ownership and the consumption of fruits and vegetables
Authors: Saaka Mahama , Awini Simon , Kizito Fred , Nang Eric
Published: January 2024

Objective:

This study assessed the extent to which access to home gardens associate with the frequency of fruit and vegetable (FV) consumption.

Setting:

The study was carried out in fifty rural communities in Northern Ghana where food insecurity and malnutrition including micronutrient deficiencies are prevalent.

Design:

A community-based comparative analytical cross-sectional study.

Participants:

A sample of 847 randomly selected rural households.

Results:

The proportion of households that consumed FV at least 3 d in a week was 45 %. Members in households who owned a home garden were 1·5 times more likely to consume FV at least 3 d in a week (adjusted OR (AOR) = 1·46 (95 % CI 1·06–2·0)), compared with their counterparts who had no home gardens. Furthermore, households in which mothers had a positive attitude towards FV consumption were 1·6 times more likely to consume FV (AOR = 1·63 (95 % CI 1·17–2·27)) compared with mothers who were less positive.

Conclusions:

Our results suggest that food and nutrition policy measures that promote home gardens can improve consumption of diversified diets including FV among vulnerable rural households in Northern Ghana. Additionally, households with lower income may benefit from nutrition behaviour change communication campaigns directed towards increasing a positive attitude to FV intake.
The gift of here and now at the end of life: Mindful living and dignified dying among Asian terminally ill patients
Authors: Choo Ping Ying , Tan-Ho Geraldine , Low Xinyi Casuarine , Patinadan Paul Victor , Ho Andy Hau Yan
Published: January 2024

Objectives

In Chochinov’s dignity model, living in the here and now (mindful living) is explicitly stated as a dignity-conserving practice. However, what facilitates mindful living remain unclear. This study aims to investigate the mechanisms of mindful living among Asian terminally ill patients.

Methods

This interpretative phenomenological analysis comprised patients aged 50 and above with a prognosis of less than 12 months. Fifty interview transcripts from a larger Family Dignity Intervention study conducted in Singapore were used for the analysis.

Results

Findings revealed 12 themes that were organized into 3 axioms of mindful living for dignified dying: (a) purposive self-awareness, (b) family-centered attention, and (c) attitudes of mortality acceptance. Through purposive self-awareness, patients introspected their lived experience with illness and anticipated death to find resilience and contentment. Patients’ conscious family-centered attention revolved around their relationships, achievements, and legacy within the family, leading to a deepened sense of interconnectedness with self and beloved others at life’s end. Lastly, patients adopted nonjudgmental attitudes of mortality acceptance as they made necessary arrangements in preparation for their death, allowing them to treasure every living moment and obtain a closure in life. An empirical model of mindful living for dignified dying was developed based on these emerging themes, illustrating the interweaving of intention, attention, and attitude for facilitating meaningful living in the face of mortality.

Significance of results

Mindful living is a dignity-preserving practice, which helps terminally ill patients to find tranquility in each present moment despite their impending death. The identified mechanisms of mindful living lay important groundwork for a new understanding and possible directions for culture-specific, mindfulness-based, family-centered interventions suited to terminally ill patients in the Asian context.
Cover crop management strategies affect weeds and profitability of organic no-till soybean
Authors: Dhakal Madhav , Rui Yichao , Benson Annie R. , Hinson Philip O. , Delate Kathleen , Afshar Reza K. , Luck Brian , Smith Andrew
Published: January 2024

Cover crop residue retention on the soil surface can suppress weeds and improve organic no-till soybean (Glycine max) yield and profitability compared to a tilled system. Appropriate cereal rye (Secale cereale) fall planting date and termination methods in the spring are critical to achieve these benefits. A plot-scale agronomic experiment was carried out from September 2018 to October 2021 in Kutztown, PA, USA to demonstrate the influence of cereal rye planting date (September or October) and mechanical termination method [no-till (I & J roller-crimper, Dawn ZRX roller, and mow-ted) and tilled (plow-cultivate)] on cover crop regrowth density, weed biomass, soybean yield, and economic returns. In one out of three years, the September rye planting accumulated more cover crop biomass than the October planting, but the regrowth of the rye after roller-crimping was greater with this planting date. Cover crop planting date had no effect on total weed biomass and demonstrated varying effects on soybean grain yield and economic returns. The Dawn ZRX roller outperformed the I & J roller-crimper in effectively terminating cover crops, while the I & J roller-crimper demonstrated more uniform weed suppression and led to greater soybean yields over a span of three years. Organic no-till strategies eliminated the need for tillage and reduced variable costs by 14% over plow-cultivated plots, and generated ~19% greater net revenue across the study period (no-till vs tillage = US $845 vs US $711 ha−1). Terminating cereal rye with roller-crimping technology can be a positive investment in an organic soybean production system.
Larger Cloud Liquid Water Enhances Both Aerosol Indirect Forcing and Cloud Radiative Feedback in Two Earth System Models

Published: January 2024

Previous studies have noticed that the Coupled Model Intercomparison Project Phase 6 (CMIP6) models with a stronger cooling from aerosol‐cloud interactions (ACI) also have an enhanced warming from positive cloud feedback, and these two opposing effects are counter‐balanced in simulations of the historical period. However, reasons for this anti‐correlation are less explored. In this study, we perturb the cloud ice microphysical processes to obtain cloud liquid of varying amounts in two Earth System Models (ESMs). We find that the model simulations with a larger liquid water path (LWP) tend to have a stronger cooling from ACI and a stronger positive cloud feedback. More liquid clouds in the mean‐state present more opportunities for anthropogenic aerosol perturbations and also weaken the negative cloud feedback at middle to high latitudes. This work, from a cloud state perspective, emphasizes the influence of the mean‐state LWP on effective radiative forcing due to ACI (ERFACI).

Air‐sea exchanges across oceanic fronts are critical in powering cloud formation, precipitation, and atmospheric storms. Oceanic submesoscale fronts of scales 1–10 km are characterized by strong sea surface temperature (SST) gradients. However, it remains elusive how submesoscale fronts affect the overlying atmosphere due to a lack of high‐resolution observations or models. Based on rare high‐resolution in situ observations in the Kuroshio Extension region, we quantify the air‐sea exchanges across an oceanic submesoscale front. The cross‐front SST and turbulent heat flux gradients reaches 2.4°C/km and 47 W/m2/km, respectively, far stronger than that typically found in mesoscale‐resolving products. The stronger SST gradient drives substantially stronger air‐sea fluxes and vertical mixing than mesoscale fronts, enhancing cloud formations. The intense air‐sea exchanges across submesoscale fronts are confirmed in idealized model simulations, but not resolved in mesoscale‐resolving climate models. Our finding provides essential knowledge for improving simulations of cloud formation, precipitation, and storms in climate models.

The formation of large igneous provinces (LIPs) has been widely believed to be linked to mantle plume activity. However, how the plume modifies the overlying lithosphere, particularly its compositional structure, remains uncertain. Here, we characterize the deep thermochemical structure beneath the Emeishan LIP (ELIP), which is a well‐known Permian plume‐related LIP in China, by taking a multi‐observable probabilistic inversion. Our results find a clear correlation between the lithospheric composition with the ELIP's concentric zones. We infer that the fertile feature of the lithospheric mantle in the ELIP's inner zone was caused by the plume‐derived fertile magmas which infiltrated into and chemically refertilized the ambient depleted lithosphere. This plume‐modified lithospheric compositional structure is likely to be preserved after the plume event, while the present lithospheric thermal structure has been mainly influenced by the subsequent thermal‐tectonic activity. Our results improve our understanding of the physicochemical interactions between the lithosphere and ancient plume.

From continuous high‐frequency and high‐resolution observations of temperature, salinity, current and microstructure in the northern South China Sea during 28–31 May 2021, we found that the transition layer (TL) experienced a regular diurnal vertical fluctuation of ∼20–30 m, likely associated with the displacements of the mixed layer (ML) and tidal shear in the TL. Specifically, surface cooling (heating) caused an erosion (enhancement) of thermal stratification and facilitated (hindered) convection, rapidly deepening (shoaling) the ML and causing corresponding vertical displacements in the TL. The mixture of diurnal and semidiurnal tides, together with internal tides and tidal rectification, resulted in a diurnally varying large shear in the TL. This enhanced shear caused the TL to further descend along with the rapid thickening of the ML, while the relatively weaker shear slowed the uplift of the TL with a rapid shoaling of the ML and resulted in its gradual shoaling.

A working Direct Analytic Method (DAM) model is envisaged to explain the normal modes of poloidal Alfven waves in the Earth's magnetosphere. The model solves the ideal, cold, magnetohydrodynamic (MHD) equations associated with transverse components of the magnetic perturbations in a dipolar magnetic field. DAM model is used to study the transverse poloidal waves in different regions of magnetosphere characterized by their L‐value and different plasma variability. The plasma density distribution is assumed to be governed by the standard power law, 1/rm, where r is the geocentric distance of any point of interest on the field line and m is the density index. The eigen frequencies and spatial structures are obtained analytically under different ideal ionospheric boundary conditions and the results are compared with the numerical solutions to establish the validity of the model. DAM, being an analytic model, is used to explain the distinctive structural features of transverse poloidal waves which are obtained under different boundary conditions, for different density indices. Furthermore, the application of the analytic model in the computation of eigen frequency as well as plasma density is demonstrated under different observational scenario.

Flood characteristics caused by extreme sea level (ESL) events depend largely on the magnitude of peak water levels (WLs) and their temporal evolution. However, coastal flood risk is generally assessed based on only a limited number of potential peak WLs and a selection of past events or a design hydrograph. We address this gap and systematically estimate (a) spatial annual and (b) event‐based flood probabilities by comprehensively accounting for both a wide range of peak ESLs and their temporal evolution, herein referred to as hydrograph intensity. We simulate flooding at the German Baltic Sea coast with the hydrodynamic model Delft3D. We produce probabilistic flood maps, which detail flood exposed areas together with annual probability of flooding. Additionally, we show how the flood extent changes, when accounting for upper, median, and lower quantiles of hydrograph intensities. Our results demonstrate that the relevance of the intensity is site and ESL dependent. While flood extents of some ESLs of the upper and lower intensity bounds indicate no differences, others differ by up to 45%. Further, we consider two ESLs (2.24 and 2.55 m) and simulate 100 intensities for each. Compared to intensity quantiles, this results in flood extents of up to 60% difference. Hence, we find that quantiles of intensity do not cover the full range when addressing uncertainty due to hydrograph variability. We, therefore, recommend accounting for a wide range of hydrograph intensities in addition to using a wide range of ESL in future flood risk assessments.

Sediment cores from blue holes have emerged as a promising tool for extending the record of long‐term tropical cyclone (TC) activity. However, interpreting this archive is challenging because storm surge depends on many parameters including TC intensity, track, and size. In this study, we use climatological‐hydrodynamic modeling to interpret paleohurricane sediment records between 1851 and 2016 and assess the storm surge risk for Long Island in The Bahamas. As the historical TC data from 1988 to 2016 is too limited to estimate the surge risk for this area, we use historical event attribution in paleorecords paired with synthetic storm modeling to estimate TC parameters that are often lacking in earlier historical records (i.e., the radius of maximum wind for storms before 1988). We then reconstruct storm surges at the sediment site for a longer time period of 1851–2016 (the extent of hurricane Best Track records). The reconstructed surges are used to verify and bias‐correct the climatological‐hydrodynamic modeling results. The analysis reveals a significant risk for Long Island in The Bahamas, with an estimated 500‐year stormtide of around 1.63 ± 0.26 m, slightly exceeding the largest recorded level at site between 1988 and 2015. Finally, we apply the bias‐corrected climatological‐hydrodynamic modeling to quantify the surge risk under two carbon emission scenarios. Due to sea level rise and TC climatology change, the 500‐year stormtide would become 2.69 ± 0.50 and 3.29 ± 0.82 m for SSP2‐4.5 and SSP5‐8.5, respectively by the end of the 21st century.
Crater Populations of the Saturnian Satellites Mimas, Rhea, and Iapetus

The Saturnian system has been explored by four spacecraft: Pioneer 11, Voyager 1 and 2, and Cassini. Only the last three took images suitable for photogeologic analysis of the surfaces of Saturn's moons, and over the decades, several research groups have published data about the crater distributions on the Saturnian satellites. These groups have used those data to draw conclusions about the impactor populations and resurfacing histories of the moons, but no one has examined how well the different data agree between the researchers. We present independent mapping of the crater populations of Saturn's moons Mimas, Rhea, and Iapetus, and compare them with many published crater populations. We found that Mimas data are the most consistent between different researchers, and Rhea data are the least consistent. We attribute these differences to (a) data biases where there are fewer images upon which to map Mimantean craters but a large variety exist for Rhean, and (b) Rhea likely has different terrains with different impact crater populations which have not been generally recognized before. We also found that Iapetus' small craters appear to have a shallow branch, as others have found, and that shallow branch is not attributable to completeness limitations. Other bodies have shallow branches at small diameters, too, but they are not as shallow as Iapetus's, which suggests varying impacting populations as one moves closer to Saturn, in line with others' work on planetocentric impactors.
