Modelling Stormwater Runoff Changes Induced by Ground-Mounted Photovoltaic Solar Parks: A Conceptualization in EPA-SWMM
Authors: Gullotta Aurora , Aschale Tagele Mossie , Peres David J. , Sciuto Guido , Cancelliere Antonino
Published: August 2023

A modelling framework for the simulation of stormwater runoff in ground-mounted photovoltaic solar parks is proposed. Elements in the solar park and their mutual interactions during precipitation events are conceptualized in EPA-SWMM. We demonstrate the potential of the framework by exploring how different factors influence runoff formation. Specifically, we carry out simulations for different sizes of the installation, soil types and input hyetographs. We also show the effect of ground cover, by changing the surface roughness. Outflow discharge from the park is compared to that from a reference catchment to evaluate variations of peak flow and runoff volume. Results highlight no practical changes in runoff in the short term after installation. However, in the long term, modifications in soil cover may lead to some potential increase of runoff. For instance, increments of the peak flow from the solar park up to 21% and 35% are obtained for roughness coefficient reductions of 10% and 20%, respectively. The proposed modelling approach can be beneficial for studying hydrological impacts of solar parks and thus for planning measures for their mitigation.
Fatty Acid-Binding Protein 4 is Essential for the Inflammatory and Metabolic Response of Microglia to Lipopolysaccharide

Published: August 2023

Prolonged activation of microglia leads to excessive release of proinflammatory mediators, which are detrimental to brain health. Therefore, there are significant efforts to identify pathways mediating microglial activation. Recent studies have demonstrated that fatty acid-binding protein 4 (FABP4), a lipid binding protein, is a critical player in macrophage–mediated inflammation. Given that we have previously identified FABP4 in microglia, the aim of this study was to assess whether FABP4 activity contributed to inflammation, metabolism and immune function (i.e. immunometabolism) in immortalised mouse microglia (BV-2 cells) using the proinflammatory stimulus lipopolysaccharide (LPS) to induce general microglial activation. Microglial FABP4 expression was significantly increased following exposure to LPS, an outcome associated with a significant increase in microglial proliferation rate. LPS-stimulated BV-2 microglia demonstrated a significant increase in the production of reactive oxygen species (ROS) and tumour necrosis factor-alpha (TNF-α), phosphorylation of c-Jun N-terminal kinase (JNK), increased expression of Toll-like receptor 4 (TLR4), and reduced expression of uncoupling protein 2 (UCP2), all of which were reversed following FABP4 genetic silencing and chemical inhibition with BMS309403. The oxidation rate of 3H-oleic acid and microglial uptake of 3H-2-deoxy-D-glucose were modulated with LPS activation, processes which were restored with genetic and chemical inhibition of FABP4. This is the first study to report on the critical role of FABP4 in mediating the deleterious effects of LPS on microglial immunometabolism, suggesting that FABP4 may present as a novel therapeutic target to alleviate microglia-mediated neuroinflammation, a commonly reported factor in multiple neurodegenerative diseases.

Does context matter? The gendered impact of study conditions on dropout intentions from higher education
Authors: Marczuk Anna , Strauss Susanne
Published: August 2023

This paper aims to understand how study conditions impact men and women’s dropout intentions differently. As a first step, we analyse the gendered impact of three aspects of study conditions that were at the centre of the Bologna Process: achievement norms, the structure of the curriculum and practical components in the study programme. As a second step, we aim to understand how individual-level differences between men and women (performance, academic self-efficacy and perceived psychological burdens) mediate this gendered impact of study conditions on dropout intentions. We use the German Student Survey data (2000–2016), which allows for valid measurement of study conditions at the subject group level. Our results show that women’s dropout intentions tend to increase in study contexts with high achievement norms, while men benefit more than women from highly structured study contexts. The practical component, in turn, lowers the dropout intentions of both groups equally.
Universal ontogenetic growth without fitted parameters: implications for life history invariants and population growth
Authors: Escala Andrés
Published: August 2023

Since the work of von Bertalanffy (Q Rev Boil 32:217–231, 1957), several models have been proposed that relate the ontogenetic scaling of energy assimilation and metabolism to growth, which are able to describe ontogenetic growth trajectories for living organisms and collapse them onto a single universal curve (West et al. in Nature 413:628–631, 2001; Barnavar et al. in Nature 420:626, 2002). Nevertheless, all these ontogenetic growth models critically depend on fitting parameters and on the allometric scaling of the metabolic rate. Using a new metabolic rate relation (Escala in Theor Ecol 12(4):415–425, 2019) applied to a Bertalanffy-type ontogenetic growth equation, we find that ontogenetic growth can also be described by a universal growth curve for all studied species, but without the aid of any fitting parameters (i.e., no fitting procedure is performed on individual growth curves). We find that the inverse of the heart frequency $$\mathrm f_H$$

f
H

, rescaled by the ratio of the specific energies for biomass creation and metabolism, defines the characteristic timescale for ontogenetic growth. Moreover, our model also predicts a generation time and lifespan that explain the origin of several “Life History Invariants’ (Charnov in Oxford University Press, Oxford, 1993) and predict that the Malthusian parameter should be inversely proportional to both the generation time and lifespan, in agreement with the data in the literature (Duncan et al. in Ecology 88:324–333 2007; Dillingham et al. in Paper 535, 2016; Hatton et al. in PNAS 116(43):21616–21622 2019). In our formalism, several critical timescales and rates (lifespan, generation time, and intrinsic population growth rate) are all proportional to the heart frequency $$\mathrm f_H$$

Mindfulness and financial well-being: multiple mediation of intrinsic career goals and work need satisfaction
Authors: Wu Xuan , Huang Shi-Zheng , Lakkanawanit Pankeawta
Published: August 2023

The goal of the current study is to investigate the relationship between mindfulness and financial well-being, for which the multiple mediating influences of intrinsic career goals and work need satisfaction are considered in combination with the self-determination theory. To verify the claimed association, a questionnaire study was conducted to gather information from 358 working adults in three under-developed regions of China. The results show that mindfulness positively influenced financial well-being. At the same time, intrinsic career goals and work need satisfaction act as parallel mediators between mindfulness and financial well-being. Nevertheless, the results don’t support the chained mediation from intrinsic career goals to work need satisfaction between mindfulness and financial well-being. Such findings offer insightful recommendations for enhancing financial well-being in the workplace through self-regulation of behaviours.
Charles Peirce’s Philosophy and the Intersection Between Biosemiotics and the Philosophy of Biology
Authors: Rodríguez Higuera Claudio
Published: August 2023

Charles S. Peirce’s philosophy of signs, generally construed as the foundation of current semiotic theory, offers a theory of general perception with significant implications for the notion of subjectivity in organisms. In this article, we will discuss Peirce’s primary claims in semiotic theory, particularly focusing on their relevance to biosemiotics. We argue that these claims align with certain areas of the philosophy of biology, specifically epistemological and ontological considerations, despite the limited formal interaction between disciplines. This article serves as a general introduction to Peircean biosemiotics as a philosophical perspective on biological subjectivity.
Physiology of Stretch-Mediated Hypertrophy and Strength Increases: A Narrative Review

Published: August 2023

Increasing muscle strength and cross-sectional area is of crucial importance to improve or maintain physical function in musculoskeletal rehabilitation and sports performance. Decreases in muscular performance are experienced in phases of reduced physical activity or immobilization. These decrements highlight the need for alternative, easily accessible training regimens for a sedentary population to improve rehabilitation and injury prevention routines. Commonly, muscle hypertrophy and strength increases are associated with resistance training, typically performed in a training facility. Mechanical tension, which is usually induced with resistance machines and devices, is known to be an important factor that stimulates the underlying signaling pathways to enhance protein synthesis. Findings from animal studies suggest an alternative means to induce mechanical tension to enhance protein synthesis, and therefore muscle hypertrophy by inducing high-volume stretching. Thus, this narrative review discusses mechanical tension-induced physiological adaptations and their impact on muscle hypertrophy and strength gains. Furthermore, research addressing stretch-induced hypertrophy is critically analyzed. Derived from animal research, the stretching literature exploring the impact of static stretching on morphological and functional adaptations was reviewed and critically discussed. No studies have investigated the underlying physiological mechanisms in humans yet, and thus the underlying mechanisms remain speculative and must be discussed in the light of animal research. However, studies that reported functional and morphological increases in humans commonly used stretching durations of > 30 min per session of the plantar flexors, indicating the importance of high stretching volume, if the aim is to increase muscle mass and maximum strength. Therefore, the practical applicability seems limited to settings without access to resistance training (e.g., in an immobilized state at the start of rehabilitation), as resistance training seems to be more time efficient. Nevertheless, further research is needed to generate evidence in different human populations (athletes, sedentary individuals, and rehabilitation patients) and to quantify stretching intensity.

Published: August 2023

Two-dimensional transition metal carbides and nitrides (MXene) have emerged as promising candidates for microwave absorption (MA) materials. However, they also have some drawbacks, such as poor impedance matching, high self-stacking tendency, and high density. To tackle these challenges, MXene nanosheets were incorporated into polyacrylonitrile (PAN) nanofibers and subsequently assembled into a three-dimensional (3D) network structure through PAN carbonization, yielding MXene/C aerogels. The 3D network effectively extends the path of microcurrent transmission, leading to enhanced conductive loss of electromagnetic (EM) waves. Moreover, the aerogel’s rich pore structure significantly improves the impedance matching while effectively reducing the density of the MXene-based absorbers. EM parameter analysis shows that the MXene/C aerogels exhibit a minimum reflection loss (RLmin) value of − 53.02 dB (f = 4.44 GHz, t = 3.8 mm), and an effective absorption bandwidth (EAB) of 5.3 GHz (t = 2.4 mm, 7.44–12.72 GHz). Radar cross-sectional (RCS) simulations were employed to assess the radar stealth effect of the aerogels, revealing that the maximum RCS reduction value of the perfect electric conductor covered by the MXene/C aerogel reaches 12.02 dB m2. In addition to the MA performance, the MXene/C aerogel also demonstrates good thermal insulation performance, and a 5-mm-thick aerogel can generate a temperature gradient of over 30 °C at 82 °C. This study provides a feasible design approach for creating lightweight, efficient, and multifunctional MXene-based MA materials.
Collective Bargaining and Gender Equality
Authors: Pillinger Jane , Wintour Nora
Published: August 2023

Collective bargaining has been a major force in delivering social justice and decent work in the workplace. However, the role of collective bargaining in achieving gender equality in the workplace is relatively under-researched.

In this book, Jane Pillinger and Nora Wintour investigate the complex and expanding area of collective union action for women's rights in the workplace. They explore how the feminization of unions in both developing and developed countries is changing bargaining agendas to address such issues as equal pay for work of equal value, work-life balance, maternity and parental leave rights, non-discrimination in access to employment, and the spill-over of domestic violence into the workplace.

The authors examine recent policy developments by the International Labour Organization, the United Nations, and the European Union, alongside many examples of national and industry-specific collective agreements to showcase how collective bargaining can be an effective tool for progressing equality in the workplace.
The Indian Economy
Authors: McCartney Matthew
Published: August 2023

The Indian economy has undergone dramatic changes over recent decades encompassing episodes of rapid growth and stagnation. It is a complex economic story that stretches back to the seismic events of 1947. This book charts the development of the Indian economy since independence and partition, and provides a rigorous presentation of India's contemporary political economy.

As well as providing a comprehensive survey of the main features of the Indian economy, the book critically examines key debates surrounding the country's economic trajectory, in particular those that link it to the dominance of particular class interests, and those that argue that India's economic growth has not delivered equivalent welfare gains. Throughout, the book uses revealing case studies of poverty and inequality, of education, health, work and gender issues to outline the human story behind the economic figures and performance indicators. The economic impact of internal geography, regional diversity and discrimination is also assessed. The distinct, and sometimes puzzling, features of India's political economy are explored, including the significance of the service sector, a weakening state, and the democratic failure of public service delivery.

The book offers an authoritative overview of the contemporary Indian economy suitable for students seeking an introduction to this most diverse of economies.
Degrowth
Authors: Kallis Giorgos
Published: August 2023

The term 'degrowth' has emerged within ecological and other heterodox schools of economics as a critique of the idea (and ideology) of economic growth. Degrowth argues that economic growth is no longer desirable - its costs exceed its benefits - and advocates a transformation of economies so that they produce and consume less, differently and better.

Giorgos Kallis provides a clear and succinct guide to the central ideas of degrowth theory and explores what it would take for an economy to transition to a position that enables it to prosper without growth. The book examines how mainstream conceptualizations of the economy are challenged by degrowth theory and how degrowth draws on a multifaceted network of ideas across disciplines to shed new light on the economic process. The central claims of the degrowth literature are discussed alongside some key criticisms of them. Whether one agrees or disagrees with degrowth's critique of economic growth, Kallis shows how it raises fundamental questions about the workings of capitalism that we can no longer afford to ignore.
Multi-fidelity and multi-objective aerodynamic short nacelle shape optimisation under different flight conditions

Published: August 2023

Throughout the course of a flight mission, a range of aerodynamic conditions, including design-point conditions and off-design conditions, are encountered. As the bypass ratio increases and the fan-pressure ratio decreases to reduce the engine’s specific fuel consumption, the engine diameters increase, which results in an increase in the nacelle weight and overall drag. To reduce its weight and drag, a shorter nacelle with a length-to-diameter ratio
$L/D = 0.35$
is investigated. In this study, an adaptive cokriging-based multi-objective optimisation method is applied to the design of a short aero-engine nacelle. Two nacelle performance metrics were employed as the objective functions for the optimisation routine. The cruise drag coefficient is evaluated under cruise conditions, whereas the intake pressure recovery is evaluated under takeoff conditions. The cokriging metamodel are refined using an effective infilling strategy, where high-fidelity samples are infilled via the modified Pareto fitness, and low-fidelity samples are infilled via the Pareto front. By combining parameterised geometry generation, automated mesh generation, numerical simulations, surrogate model construction, Pareto front exploration based on the non-dominated sorting genetic algorithm-II and sample infilling, an integrated multi-objective optimisation framework for short aero-engine nacelles is developed. Two-objective and three-objective test functions are used to validate the effectiveness of the proposed framework. After the optimisation process, a set of non-dominated nacelle designs is obtained with better aerodynamic performance than the original design, demonstrating the effectiveness of the optimisation framework. Compared with the kriging-based optimisation framework, the cokriging-based optimisation framework outperforms the single-fidelity method with a higher hypervolume value at the same number of iteration loops.

On December 8, 2022, in a case relating to a de-referencing request to an internet search engine operator on the basis of inaccurate information, the Grand Chamber of the Court of Justice of the European Union (CJEU) delivered its judgment (the Judgment) on the interpretation of the right to erasure (right to be forgotten) under Article 17 of the EU General Data Protection Regulation 2016/679 (GDPR), and the rights of access and objection under Articles 12 and 14 of the EU Directive 95/46/EC (the Directive), in light of fundamental rights to privacy, protection of personal data, and freedom of expression and information under Articles 7, 8, and 11 of the Charter of Fundamental Rights of the European Union (the Charter). The case establishes that the burden of proof is on the person requesting de-referencing to show manifest inaccuracy of information, but this does not require them to seek a judicial remedy against the website publisher before requesting de-referencing. Although the search engine operator is obliged to carry out checks to confirm the merits of the request, it has no obligation to investigate the facts and probe further with the website publisher. However, it must de-reference where relevant and sufficient evidence is submitted to show manifest inaccuracy, and it must display a warning where it is made aware of judicial proceedings.
RNA N6-methyladenosine of DHAPAT and PAP involves in regulation of diapause of Bombyx mori via the lipid metabolism pathway

Published: August 2023

Environment-induced epigenetics are involved in diapause regulation, but the molecular mechanism that epigenetically couples nutrient metabolism to diapause regulation remains unclear. In this study, we paid special attention to the significant differences in the level of N6-adenosine methylation (m6A) of dihydroxyacetone phosphate acyltransferase (DHAPAT) and phosphatidate phosphatase (PAP) genes in the lipid metabolism pathway of the bivoltine silkworm (Bombyx mori) strain Qiufeng developed from eggs incubated at a normal temperature (QFHT, diapause egg producer) compared to those from eggs incubated at a low temperature (QFLT, non-diapause egg producer). We knocked down DHAPAT in the pupal stage of the QFLT group, resulting in the non-diapause destined eggs becoming diapausing eggs. In the PAP knockdown group, the colour of the non-diapause destined eggs changed from light yellow to pink 3 days after oviposition, but they hatched as normal. Moreover, we validated that YTHDF3 binds to m6A-modified DHAPAT and PAP mRNAs to promote their stability and translation. These results suggest that RNA m6A methylation participates in the diapause regulation of silkworm by changing the expression levels of DHAPAT and PAP and reveal that m6A epigenetic modification can be combined with a lipid metabolism signal pathway to participate in the regulation of insect diapause traits, which provides a clearer image for exploring the physiological basis of insect diapause.

Biochar is increasingly used in crop production as a fertilizer; however, its effects on nutrient cycling and stoichiometry in rice paddy soil–plant systems are unclear. We tested for effects of contrasting rates of biochar on soil and rice plant organ carbon (C), nitrogen (N), and phosphorus (P) concentrations and stoichiometry and soil physicochemical properties in early and late paddies. Overall, biochar reduced soil bulk density by an average of 7.4%, while application at 10, 20, and 40 t ha−1 increased soil C and N concentrations in early paddies by 31.6, 41.3, and 104.2%, respectively, and by 8.0, 5.0, and 21.8%, respectively; in late paddies, there were increases of 23.0, 94.1, and 117.0%, respectively, and 6.7, 15.4, and 18.0%, respectively (P < 0.05). Following biochar application at 10, 20, and 40 t ha−1, soil concentration of P decreased in early paddies by 10.9, 19.0, and 13.9%, respectively, and increased in late paddies by 4.3, 16.4, and 20.1%, respectively. Biochar increased ratios of soil C:N and C:P in early and late paddies (P < 0.05), and there was no effect on concentration and stoichiometry of soil available nutrients. Biochar reduced rice plant organ concentration of N and P in early rice and increased leaf N:P ratios. Despite the biochar application improved nutrient status in plant–soil system, we did not observe a significant increase in yield (P > 0.05). According to the N:P value of leaves between treatments, it was found that biochar alleviated the current situation of N limitation in paddy fields during the mature period and transformed the N limitation of early rice into a joint limitation of N and P. These results show that the addition of biochar to subtropical paddy soils leads to a short-term reduction in soil bulk density and increases in soil C and N concentrations and soil fertility. Thus, biochar applied at optimal rates is likely to improve the sustainability of subtropical paddy rice production.
Gathering Souls: Jesuit Missions in the Spanish Empire
Authors: Coello de la Rosa Alexandre
Published: August 2023

This article examines two different missionary areas where the Society of Jesus was sent to evangelise the native population: the Andean territories previously under Inca domination and the remote Mariana Islands in the Pacific Rim. The gathering of “other barbarians” living outside “civilised” societies was a tool of early modern colonisers within Europe and beyond. The English did so in sixteenth-century Ireland and the Spanish began reducing the so-called American Indians to new settlements in New Spain and Peru. In this paper, I want to compare the methods used to concentrate the natives of the Viceroyalty of Peru, where the Jesuits actively collaborated, with the borderland mission of the Marianas, where the Jesuits worked as parishioners of a much less sophisticated people: the CHamoru.1 As I will demonstrate, this policy of gathering souls was not an isolated one, but part and parcel of a universalistic principle of spreading God's word that was irremediably embedded in colonial structures of coercion and political control in the Americas and Asia-Pacific.
A FIFTEENTH-CENTURY OTTOMAN SOLUTION TO THE LIAR PARADOX BY ḪAṬĪBZĀDE MUḤYIDDĪN
Authors: Daşdemir Yusuf
Published: August 2023

This paper deals with a solution to the infamous liar paradox, usually known in the Arabic literature as Maġlaṭat al-ǧaḏr al-aṣamm. The solution is raised by a fifteenth-century Ottoman treatise that is attributed, among others, to Ḫaṭībzāde Muḥyiddīn Efendī. The paper also compares it with the solution by the contemporary Persian philosopher, Ǧalāl al-Dīn al-Dawānī. The short treatise devoted to the paradox is one of the few works by Ottomans on the subject and it comprehensively addresses the paradox in its two forms. An analysis of the solution offered by the treatise to the paradox, the paper aims to bring Ottoman discussions of the liar to the attention of contemporary scholarship and contribute to filling the obvious gap in the literature on the paradox in Islamic thought.
Sensitivity of TamArk™ grain sorghum and monocot weed species to ACCase- and ALS-inhibiting herbicides
Authors: Fleming Jacob , Norsworthy Jason K. , Bagavathiannan Muthukumar , Barber Tom
Published: August 2023

Only a limited number of herbicides are available to provide postemergence (POST) control of selective monocot weeds in grain sorghum crops. The herbicides currently labeled for use with grain sorghum have strict use restrictions, low efficacy on johnsongrass, or weed resistance issues. To introduce a new effective herbicide mode of action for monocot control, multiple companies and universities have been developing herbicide-resistant grain sorghum that would allow producers to use herbicides that inhibit either acetolactate synthase (ALS) or acetyl coenzyme A carboxylase (ACCase) for POST monocot control. An experiment was conducted in Fayetteville, AR, in 2020 and 2021, to determine the effectiveness of two ALS-inhibiting herbicides and nine ACCase-inhibiting herbicides on TamArk™ grain sorghum, conventional grain sorghum, and problematic monocot weed species. Grain sorghum and monocot weeds (johnsongrass, broadleaf signalgrass, barnyardgrass, and Texas panicum) were sprayed when TamArk grain sorghum reached the 2- to 3-leaf stage. TamArk grain sorghum was tolerant of all ACCase-inhibiting herbicides tested, exhibiting ≤10% injury at all evaluation timings, except clethodim and sethoxydim, and had no resistance to the ALS-inhibiting herbicides that were evaluated. Additionally, all ACCase inhibitors except diclofop and pinoxaden controlled all monocots tested by >91% at 28 d after application (DAA). Conversely, the two ALS inhibitors, imazamox and nicosulfuron, provided ≤81% control of broadleaf signalgrass 28 DAA but still controlled all other monocots by >95%. TamArk grain sorghum has low sensitivity to multiple ACCase-inhibiting herbicides and thus provides an effective POST option for monocot weed control. In addition, unwanted volunteer TamArk plants can be controlled with cledthodim, sethoxydim, nicosulfuron, or imazamox. Although the ALS-inhibiting herbicides imazamox and nicosulfuron were not useful on TamArk grain sorghum, they are effective options for monocot control on Igrowth™ and Inzen™ grain sorghum crops, respectively.
Interference of Brassicaceae weeds (Brassica tournefortii, Rapistrum rugosum, and Sisymbrium thellungii) in chickpea
Authors: Mahajan Gulshan , Chauhan Bhagirath Singh
Published: August 2023

African mustard (Brassica tournefortii Gouan), turnipweed [Rapistrum rugosum (L.) All.], and African turnipweed (Sisymbrium thellungii O.E. Schulz) are common broadleaf weeds in chickpea (Cicer arietinum L.) crops, particularly under dryland region conditions in eastern Australia. Information on crop yield losses and the seed production potential for these weeds in chickpea are limited. Field studies were conducted in the winter seasons of 2020 and 2021 in eastern Australia with different densities of the three weeds (B. tournefortii, R. rugosum, and S. thellungii) in chickpea. Based on the sigmoidal model, chickpea yield was reduced by 50% at 11 plants m−2 of B. tournefortii. Based on hyperbolic models, a 50% yield reduction of chickpea occurred at 5 and 25 plants m−2 of R. rugosum and S. thellungii, respectively. Based on the linear model, B. tournefortii, R. rugosum, and S. thellungii produced a maximum of 448,000, 206,700, and 869,400, seeds m−2, respectively. At chickpea harvest, the low seed retention (<55%) of B. tournefortii and S. thellungii suggests limited opportunities for harvest weed seed control, and the seed rain of these weeds may enrich the weed seedbank in the soil. At crop harvest, the seed retention of R. rugosum was found to be greater than 90%, suggesting that it is a suitable candidate for harvest weed seed control. This study demonstrated that R. rugosum could cause a greater reduction in chickpea yield compared with B. tournefortii and S. thellungii. Furthermore, restricting seed rain of B. tournefortii and S. thellungii by not allowing the plants to produce seeds is recommended to reduce their weed seedbanks in the soil. The information generated from this study could aid in strengthening integrated weed management in chickpea.
High seeding rates, interrow mowing, and electrocution for weed management in organic no-till planted soybean

Published: August 2023

No-till planting organic soybean [Glycine max (L.) Merr.] into roller-crimped cereal rye (Secale cereale L.) can have several advantages over traditional tillage-based organic production. However, suboptimal cereal rye growth in fields with large populations of weeds may result in reduced weed suppression, weed–crop competition, and soybean yield loss. Ecological weed management theory suggests that integrating multiple management practices that may be weakly effective on their own can collectively provide high levels of weed suppression. In 2021 and 2022, a field experiment was conducted in central New York to evaluate the performance of three weed management tactics implemented alone and in combination in organic no-till soybean planted into both cereal rye mulch and no mulch: (1) increasing crop seeding rate, (2) interrow mowing, and (3) weed electrocution. A nontreated control treatment that did not receive any weed management and a weed-free control treatment were also included. Cereal rye was absent from two of the five fields where the experiment was repeated; however, the presence of cereal rye did not differentially affect results, and thus data were pooled across fields. All treatments that included interrow mowing reduced weed biomass by at least 60% and increased soybean yield by 14% compared with the nontreated control. The use of a high seeding rate or weed electrocution, alone or in combination, did not improve weed suppression or soybean yield relative to the nontreated control. Soybean yield across all treatments was at least 22% lower than in the weed-free control plot. Future research should explore the effects of the tactics tested on weed population and community dynamics over an extended period. Indirect effects from interrow mowing and weed electrocution should also be studied, such as the potential for improved harvestability, decreased weed seed production and viability, and the impacts on soil organisms and agroecosystem biodiversity.

Published: August 2023

Abstract: Background The outcomes of calling 911 for suicide crises remain largely unexplored. Aims To investigate how characteristics of individuals in a suicidal crisis (e.g., age, gender identity, help-seeking source, means, disclosure of historical suicidality, or self-harm) may differentiate outcomes when contacting 911. Method The authors analyzed 1,073 Washington State Police 911 call logs, coding for characteristics and outcome (unknown, monitoring, intervention, adverse outcome). Descriptive and inferential statistics, including multinomial logistic regressions, were used to explore associations. Results When individuals experiencing a suicidal crisis were referred by bystander or associates’ observations, there was a greater likelihood of adverse outcome. Self-referral led to a greater likelihood of intervention. Referral from the suicidal individual contacting a known associate led to a greater likelihood of monitoring. Any disclosure of means led to a greater likelihood of intervention or adverse outcomes. Positive disclosure of historical suicidality or self-harm was more likely to result in monitoring. Limitations The dataset was intended for operational use in acute suicidality triage rather than research purposes. Conclusion This study highlights the importance of supporting first responders with research to enhance their triage of people experiencing suicidal crises.
Retest Reliability of Situational Judgment Tests

Published: August 2023

Abstract: A situational judgment test (SJT) is a psychological instrument typically used to assess the suitability of applicants in personnel selection or development. Interest in SJTs has increased over the past decades as research has shown considerable validity of SJTs and various other benefits. Researchers often provide information about internal consistency reliability of SJTs, but this estimate is known to be unsuitable for SJTs because they are heterogeneous tests; a better estimate for the reliability of SJTs may be retest reliability. Thus, this study represents the first meta-analysis investigating the retest reliability of SJTs. The results reveal a pooled retest reliability estimate of r = .698 based on k = 37 coefficients. Additionally, variables associated with test characteristics and variables containing information about the study and the participants were examined as potential moderators.
A Bayesian Regression Analysis of the Effects of Narcissism on Group Performance
Authors: Gunnesch-Luca George , Paul Karsten I. , Moser Klaus
Published: August 2023

Abstract: Though people high in narcissism have high self-esteem and appear as charming, their long-term relationships are problematic due to their difficult interpersonal style, which suggests that maintaining sound exchange relationships with narcissists is difficult. Because work teams must rely on continuing and reliable exchange processes, narcissistic team members should be detrimental to their functioning. We investigated this hypothesis by collecting data from 110 work groups from various organizations and analyzing the association between narcissism-based group composition indices and team performance. Using Bayesian inference, the results show that narcissism in work groups is negatively related to interpersonal forms of citizenship behavior, but not to citizenship behaviors that target the organization. Furthermore, group task performance was also negatively affected by narcissism within the team.

The positive Ti isotope versus SiO2‐content correlation in igneous rocks reflects the fractional crystallization of Ti‐bearing oxide minerals. However, Ti isotope variations of subduction‐related igneous rocks indicate that the Ti isotope compositions of their mantle sources are heterogeneous and additional mineral phases may promote Ti isotope fractionation. We have determined the Ti isotope composition of well‐characterized subduction‐related basalts, andesites and boninites. Samples from the Solomon Islands, the Troodos ophiolite in Cyprus, and Cape Vogel in Papua New Guinea show small but resolvable variations that may be related to differences in their mantle sources. Specifically, the δ49Ti of boninites (+0.109‰ to +0.168‰) is slightly higher than that of tholeiites (−0.027‰ to +0.111‰) from the same localities (Troodos in Cyprus and Cape Vogel in Papua New Guinea). Modeling suggests the partial melting of progressively depleted mantle sources where residual Cr‐spinel plays a greater role in controlling the Ti budget during partial melting. More pronounced variations in δ49Ti are clearly linked to the fractional crystallization of Ti‐oxides: Samples from Rabaul Volcanic Complex (New Britain, Papua New Guinea) show increasing δ49Ti (up to +0.373‰) with increasing Ti/V and decreasing Dy/Yb. Fractional crystallization models suggest that oxide minerals and amphibole are needed to sufficiently increase the δ49Ti of these magmas. Our study highlights that the combination of diagnostic trace element patterns and Ti isotope compositions in subduction‐related igneous rocks can be a powerful tool to constrain petrogenetic processes and to discriminate between different crystallizing mineral phases.

The quantitative and objective characterization of dissolution intensity in fossil planktonic foraminiferal shells could be used to reconstruct past changes in bottom water carbonate ion concentration. Among proxies measuring the degree of dissolution of planktonic foraminiferal shells, X‐ray micro‐Computed Tomography (CT) based characterization of apparent shell density appears to have good potential to facilitate quantitative reconstruction of carbonate chemistry. However, unlike the well‐established benthic foraminiferal B/Ca ratio‐based proxy, only a regional calibration of the CT‐based proxy exists based on a limited number of data points covering mainly low‐saturation state waters. Here we determined by CT‐based proxy the shell dissolution intensity of planktonic foraminifera Globigerina bulloides, Globorotalia inflata, Globigerinoides ruber, and Trilobatus sacculifer from a collection of core top samples in the Southern Atlantic covering higher saturation states and assessed the reliability of CT‐based proxy. We observed that the CT‐based proxy is generally controlled by deep‐water Δ[] like the B/Ca proxy, but its effective range of Δ[] is between −20 and 10 µmolkg−1. In this range, the CT‐based proxy appears directly and strongly related to deep‐water Δ[], whereas we note that in some settings, there appears to be a secondary influence on B/Ca which we suggest may be due to elevated alkalinity from carbonate dissolution in sediments. On the other hand, the CT‐based proxy is affected by supralysoclinal dissolution in areas with high productivity. Like the B/Ca proxy, the CT‐based proxy requires species‐specific calibration, but the effect of species‐specific shell difference in susceptibility to dissolution on the proxy is small.

Given the key role that atmospheric heat transport plays in Earth's climate system, efforts to document its changes over the satellite era are valuable. Clark et al. (2022, https://doi.org/10.1029/2022GL098822) calculated trends in atmospheric heat transport among four reanalysis data sets and found substantial disagreements between data sets. However, after accounting for the lack of mass‐conservation in reanalysis data sets, we find much smaller magnitude trends, with much better agreement among reanalyses. This highlights the importance of mass corrections when calculating atmospheric heat transport.

Hydroxylated isoprenoid glycerol dialkyl glycerol tetraethers (OH‐GDGTs) preserved in marine sediments are thought to be controlled by sea surface temperature (SST). However, water depth may also exert a significant influence on OH‐GDGTs. Here, we investigated sedimentary OH‐GDGTs in the Kermadec and Atacama trench regions (2,560–9,560 m water depth). Sedimentary OH‐GDGTs in hadal trenches were dominated by OH‐GDGT‐0 (72 ± 8%), potentially reflecting an adaption of source organisms to ambient cold deep water. This result, combined with global data set, revealed that the predominance of OH‐GDGT‐0 is a ubiquitous phenomenon in deep‐sea sediments, leading to a considerable underestimation of RI‐OH′‐derived SSTs. By considering both SST and water depth effects, we developed more accurate OH‐GDGT‐based paleothermometers for both shallow regions and the global ocean, encompassing the full‐ocean‐depth range. Our findings highlight the importance of accounting for the effect of water depth on OH‐GDGTs and provide improved tools for reconstructing paleo‐SSTs.
Skillful Multiyear Prediction of the Kuroshio and Gulf Stream Jets and Eddy Activity

The Kuroshio and Gulf Stream (GS), Northern Hemisphere warm ocean currents, have narrow bands of intense jets and vigorous eddies. While the importance of them in regulating physical and biological ocean systems and climate has been increasingly recognized, the operational predictability of year‐to‐year variations in these jets and eddies has not been quantitatively assessed yet. Through a series of experiments using an eddy‐resolving dynamical ocean forecasting system, here we show that observed year‐to‐year variations in the intensities of the jets and eddies in the Kuroshio Extension and GS regions can be skillfully predicted up to a lead time of about 2 years. Sources of predictability mostly come from initial ocean memories, and variations in local atmospheric conditions play a secondary role. Our results demonstrate that the observed multiyear variations in ocean jets and eddies in these regions are operationally predictable when ocean models are properly initialized with sufficient spatial resolution.

In a previous study, we investigated whether reanalysis moist static energy (MSE) transport trends over the 1980 through 2018 period are consistent (a) with each other and (b) with the finding that these transport trends are downgradient, as found in climate models. Regarding point (a), our conclusion was that MSE transport trends were dependent on the reanalysis data set. However, Cox et al. (2023) correctly point out that the reanalysis dependence is reduced dramatically if a barotropic mass flux correction is applied at a monthly mean timescale prior to computing the MSE transport trends. In our reply below, we revisit point (b) after applying this correction. We find that even after the correction, reanalysis MSE transport trends are not downgradient nor poleward in the Northern Hemisphere extratropics. However, reanalysis does show a compensation between dry static and latent energy transport trends, which has been shown in climate models historically.
Targeted Balloon Observations of Stratosphere‐To‐Troposphere Transport From a Mesoscale Convective System

Stratosphere‐troposphere exchange (STE) is important to the global radiation budget because it is capable of inducing significant changes in trace greenhouse gases such as ozone and water vapor. In the extratropics, stratosphere‐to‐troposphere—or downward—transport (STT) dominates and is routinely driven by upper‐troposphere jet circulations and cyclones. Tropopause‐overshooting convection provides a more rapid STE pathway, but STT in convection is less understood and targeted observations are limited to a handful of fortuitous aircraft encounters. In this study, we seek to improve understanding of STT near thunderstorm anvils using balloon observations of ozone, ground‐based radar observations, visible satellite imagery, and model output. Radar and satellite imagery are used to identify and ultimately target convection driving the “ozone‐wrapping” process. Herein, observations from a single mesoscale convective system in central Oklahoma are reported. A significant ozone enhancement 40%–60% greater than background concentrations in the free troposphere was observed during the balloon ascent underneath and within the anvil of the storm. Backwards particle trajectories were calculated to rule out other sources of this feature such as long‐range transport of stratospheric air and smoke pollution from nearby wildfires. To our knowledge, this work presents the first targeted ozonesonde launch and sampling of this STT process.
