Published: July 2023

Abstract
This study determines the cause of soil erosion in red soils in sugarcane fields, especially even with the use of subsoiling fissures, and to compare the effectiveness of a novel artificial linear-macropore with the insertion of fibrous material into the fractures. Four column treatments (tillage, subsoiling, linear-macropore with plant residue fillings, and no-tillage-with-mulching) were established. A subsoiler was used to break up hard soil layers to enhance infiltration, whereas mulching reduced the impact of raindrops on the soil. Sugarcane residue was inserted in the empty fissure to reinforce the structure, making linear macropore. Simulated rainfall with 20 mmh−1 was applied to the soil surface for 6 h per day for two days. Surface runoff, soil erosion, and drainage were measured during each run. Erosion was minimal (1/7 reduction), and bottom drainage was observed in the linear-macropore and no-tillage-with-mulching plots. Conversely, due to the formation of an impermeable layer or surface crust, high erosion (0.282 t-C ha−1 yr−1) and decreased drainage levels were detected in the subsoiling and tillage plots. Moreover, the aboveground protrusion of fibrous material at the linear-macropore maintained infiltration, even following crust formation. Field application of these four management strategies revealed the effectiveness of linear-macropore and mulching in reducing surface flow. Linear-macropore application maintains appropriate levels of infiltration, and insertion of plant residue fillings reinforces the macropore structure while also avoiding clogging. Hence, the linear-macropore scheme may represent an effective strategy for reducing surface runoff and red soil erosion.
Post-Keynesian essays from down under: Theory and policy in an historical context
Authors: Kerr Prue 
Published: July 2023

Abstract‘Post-Keynesian’ became an umbrella term for those heterodox economists wanting to move away from the dominant neo-classical paradigm but not comfortable with another umbrella term of ‘political economy’. This review is about the contributions to understanding societal and economic change from an established and internationally recognised group of post-Keynesian economists. Many of the features which differentiate them from other, and sometimes fluid, subsets of post-Keynesian economists derive from their Kaleckian inspiration.
Calculation of internal-wave-driven instability and vortex shedding along a flat bottom
Authors: Ellevold Thea J. , Grue John 
Published: July 2023

The instability and vortex shedding in the bottom boundary layer caused by internal solitary waves of depression propagating along a shallow pycnocline of a fluid are computed by finite-volume code in two dimensions. The calculated transition to instability agrees very well with laboratory experiments (Carret al.,Phys. Fluids, vol. 20, issue 6, 2008, 06603) but disagrees with existing computations that give a very conservative instability threshold. The instability boundary expressed by the amplitude depends on the depth$d$of the pycnocline divided by the water depth$H$, and decays by a factor of 2.2 when$d/H$is 0.21, and by a factor of 1.6 when$d/H$is 0.16, and the stratification Reynolds number increases by a factor of 32. The instability occurs at moderate amplitude at large scale. The calculated oscillatory bed shear stress is strong in the wave phase and increases with the scale. Its non-dimensional magnitude at stratification Reynolds number 650 000 is comparable to the turbulent stress that can be extracted from field measurements of internal solitary waves of similar nonlinearity, moving along a pycnocline of similar relative depth.
CLASSICAL DETERMINATE TRUTH I
Authors: FUJIMOTO KENTARO , HALBACH VOLKER 
Published: July 2023

AbstractWe introduce and analyze a new axiomatic theory$\mathsf {CD}$of truth. The primitive truth predicate can be applied to sentences containing the truth predicate. The theory is thoroughly classical in the sense that$\mathsf {CD}$is not only formulated in classical logic, but that the axiomatized notion of truth itself is classical: The truth predicate commutes with all quantifiers and connectives, and thus the theory proves that there are no truth value gaps or gluts. To avoid inconsistency, the instances of the T-schema are restricted todeterminatesentences. Determinateness is introduced as a further primitive predicate and axiomatized. The semantics and proof theory of$\mathsf {CD}$are analyzed.

Summary
N-enriched biochar can increase the accumulation of carbon (C), nitrogen (N), phosphorus (P), and biomass in rice plants. On the other hand, the biomass and C, N, and P contents of plant organs are important indicators to reflect plant C, N, and P storages. We established control, 4 t ha−1, and 8 t ha−1 N-enriched biochar treatment plots in a subtropical paddy field in China to investigate the effect of these treatments on C, N, and P storages, ecological stoichiometry in various rice plant organs, and their relationships with edaphic factors. The application of N-enriched biochar increased the biomass and storages of C, N, and P in rice roots, stems, leaves, and grains, mainly at 4 t ha−1. The application of N-enriched biochar decreased the C/N and C/P ratios of rice organs, but increased their N/P ratio. Changes in C/N were mainly due to the changes in storage, while N/P was positively correlated with N storage of stems, leaves, and grains and negatively correlated with P storage in roots. Pearson’s correlation analysis revealed that pH was negatively correlated, and soil N content was positively correlated with P storage in various organs of rice. In addition, soil P content and chlorophyll were positively correlated with N storage. In conclusion, we found that the application of N-enriched biochar improved plant N and P storage and stoichiometrical relations among rice organs.
Elusive decolonisation of IR in the Arab world
Authors: El Kurd Dana 
Published: July 2023

AbstractArab social science scholarship, and IR in particular, has been systematically underfunded and sidelined by governments across the region. As such, IR scholars in the Arab world have struggled to produce scholarship in hostile and authoritarian environments, let alone address efforts to decolonise. Of the few initiatives of indigenising social science that exist in the Arab world, the Doha Institute for Graduate Studies (DI) and its founding institution, the Arab Center for Research and Policy Studies (ACRPS), are the main examples. In this intervention, I will review the attempts to indigenise and decolonise IR within these institutions. I focus on how the DI is implementing three main approaches: increasing access to the discipline, rethinking how we teach IR, and facilitating theory production from the region. I demonstrate the strengths and weaknesses of the three abovementioned approaches by drawing attention to performative measures on the part of regional scholars, and pretending localism on the part of scholars in the Global North, which together help to perpetuate neomarginalisation. The shortcomings discussed permeate and distort attempts to decolonise the discipline within the Arab world.
Invisible on the globe but not in the global: Decolonising IR using small island vistas
Authors: Hinds Kristina 
Published: July 2023

AbstractTeaching and studying International Relations (IR) in the Caribbean makes the region’s invisibility unmissable. Nevertheless, these locales have significantly influenced the structure of global processes and are also acutely affected by global occurrences. Exposure to the global has led Caribbean scholarship to offer worthwhile insights into world affairs. Thinkers from the region and its diaspora provide noteworthy perspectives about the criticality of the Caribbean in building systems of empire and a world structured around race, class, and gender in ways that mainstream IR approaches may miss. This article takes its starting point as the Caribbean intellectual tradition. Grounding IR scholarship in this neglected, though highly pertinent, thought tradition is one angle from which to decolonise the discipline. The article connects these insights to an appraisal of a nimble strategy that Caribbean states and territories employ to navigate the global. The strategy of developing offshore financial centres (OFCs) can educate us about the functioning of the world if we are willing to think about it as embedded in global processes rather than as a problematic gimmick. In sum, this piece illustrates how using Caribbean thought and examining Caribbean global integration strategies can help to decolonise IR.
Decolonising to reimagine International Relations: An introduction
Authors: Sen Somdeep 
Published: July 2023

AbstractSeeing as colonialism is ubiquitous to where International Relations (IR) comes from, what it explains and who it represents, many have argued that the decolonisation of the discipline is impossible. However, in this agenda-setting introduction, I place decolonisation squarely in the realm of possibility and ask, ‘what would a decolonised field look like?’. In answering this question, the contributions in this forum take point of departure from varied sites within the discipline, as they seek to materialise real change that reimagines what IR is and does as a discipline that was established as a scholarly defence for colonialism. Herein they propose decolonisation as a structure that upends the discipline’s colonial epistemological roots, rethinks core concepts and underlines the need to forefront geographies, peoples, and perspectives that were underrepresented in a colonial discipline. Equally, they recognise that decolonisation is a messy affair, that takes a non-linear trajectory. However, seeing as colonialism did not just inflict material impoverishment but also sought to alienate the colonised from their sense of self, this messiness is only expected. So, rather than be discouraged by this, this forum views the non-linear trajectory to be an unavoidable facet of any attempt at decolonising the discipline.
The role of coping in processes of resilience: The sample case of academic coping during late childhood and early adolescence

Published: July 2023

AbstractDevelopmentalists have increasingly concluded that systems approaches to resilience provide a useful higher-order home for the study of the development of coping. Building on previous work on the complementarity of resilience and coping, this paper had two goals: (1) to propose a set of strategies for examining the role of coping in processes of resilience, and (2) to test their utility in the academic domain, using poor relationships with the teacher as a risk factor, and classroom engagement as an outcome. This study examined whether coping serves as a: (1) promotive factor, supporting positive development at any level of risk; (2) pathway through which risk contributes to development; (3) protective factor that mitigates the effects of risk; (4) reciprocal process generating risk; (5) mechanism through which other promotive factors operate; (6) mechanism through which other protective factors operate; and (7) participant with other supports that shows cumulative or compensatory effects. Analyses showed that academic coping at this age was primarily a mediator of risk and support, and a promotive factor that added to engagement for students with multiple combinations of risk and support. Implications are discussed, along with next steps in exploring the role of coping in processes of resilience.

Role of bilingual experience in children's context-sensitive selective trust strategies
Authors: Yow W. Quin , Li Xiaoqian 
Published: July 2023

AbstractEarly bilingual language experience can enhance children's social-cognitive skills for effective communication. This study examined whether individual variability in bilingual language diversity, measured by language entropy, influenced 3- to 5-year-old children's engagement of contextual information in their selective trust strategies. One-hundred-and-forty Singaporean children (58 girls, Mage = 53.64 months, 97.1% Asian) were presented with an informant who provided either accurate or inaccurate information in a context with either adequate or limited information access. Bilingual children with greater language diversity, compared to those with less language diversity, were more likely to adapt their accuracy-based selective trust strategy to the informant's circumstances (i.e, information access). Results provide new insights into the role of diverse linguistic experiences in shaping children's social cognitive development.
Hysteretic Behavior of Global to Regional Monsoon Area Under CO2 Ramp‐Up and Ramp‐Down

Published: July 2023

AbstractWhen projecting future monsoon changes by carbon dioxide (CO2) pathway, most studies have analyzed precipitation responses without considering monsoon area (total area of monsoon domain, MA) variations. However, how MA responds to CO2 removal remains uncertain. This study evaluates MA variations and impacts in idealized CO2 ramp‐up (toward CO2 quadrupling), ramp‐down, and stabilized simulations using the Community Earth System Model version 1. Global MA negatively overshoots (i.e., recovery with decreasing tendency beyond the original MA) during the ramp‐down period due to reduced or rapidly recovered MA in several regional monsoons, including Northern and Southern Africa, South and East Asia, and South America, showing hysteresis when comparing CO2 ramp‐up and ramp‐down periods despite similar global warming levels. These non‐linear regional MA variations come from distinct regional summer and winter precipitation variations, which are found to be mostly associated with Intertropical Convergence Zone movements and El Niño‐like response. Further, regional monsoon precipitation characteristics also vary through CO2 ramp‐up and ramp‐down periods consistently with overall hysteresis. Changes in total monsoon precipitation resemble the distinct responses of MA. Our results suggest that regions characterized by a monsoonal climate may experience reduced seasonal rainfall variations under net‐negative CO2 emissions.

Published: July 2023

AbstractTo better understand fire regimes and their relation to climate in the seasonal tropical forests of continental Southeast Asia, we developed the first multi‐century tree‐ring based fire history chronology for the region. The chronology included 776 fire scars collected at Bidoup NuiBa National Park (BNNP) in the Central Highlands of Vietnam and spans the period 1636–2020. Fires were recorded in 116 years, representing 47% of the years covered by the 249‐year period between the first fire scar (1772) and the last (2020). While only 9% of years within the sampled BNNP forests experienced fires before 1905, 70% recorded fires between 1906 and 1963 and 90% showed evidence of fire after 1963. Fire occurrence was highly correlated with climate indices (wet season Nino 3.4 and dry season regional Palmer Drought Severity Index) during the period 1906–1963, but showed no significant correlation after 1963. Our fire reconstruction from BNNP suggests that the fire regime has shifted from one driven primarily by climate to one in which human activities dominate the occurrence of fire within these seasonal tropical landscapes.
Hydrological Object‐Based Flow Direction Model for Constructing a Lake‐Stream Topological System

Published: July 2023

AbstractThe topological system of lakes and streams is the basis for deriving a multitude of patterns and processes in hydrology, geomorphology and ecology. Flow direction is key to constructing a lake‐stream topological system. However, lakes and streams are important hydrological objects that should be considered since they are linked during the process of material and energy transportation. Therefore, a flow direction algorithm that can clearly express the topological relationship of lakes and streams, was proposed here. Lakes and streams were taken as the hydrological objects in stream networks and coupled into a flow direction algorithm. A topological system was established based on the proposed algorithms. Six areas on the Tibetan Plateau were chosen as sample areas with the MERIT digital elevation model (DEM) as the DEM data source. Streams derived from flow direction data in the HydroSHEDS data set (HYDROSTREAMS) and MERIT hydro data set (MERITSTREAMS), as well as streams derived from flow direction results of the D‐infinity algorithm and priority‐flood algorithm were compared with streams derived from the proposed algorithm. The topological relationship between streams and lakes was clearly expressed by the proposed algorithm. In lake areas, the proposed algorithm showed better performance, and no parallel streams were found. In nonlake areas, the stream networks derived from these algorithms were stable. The proposed algorithm offers an opportunity to treat lakes and streams differently during simulation, thus adding to the authenticity of the simulation.
Effect of Particulate Organic Carbon Deposition on Nitrate Reduction in the Hyporheic Zone
Authors: Ping Xue , Xian Yang , Jin Menggui 
Published: July 2023

AbstractThe hyporheic zone (HZ), where surface water and groundwater interact in sediments beneath streams, presents unique conditions for nutrient dynamics, such as carbon and nitrogen (N) cycling. Organic carbon (OC) in aquatic systems has two distinct forms: dissolved organic carbon and particulate organic carbon (POC). OC affects N reduction and controls the occurrence of denitrification, a primary process by which nitrate (NO3−) is removed as gas (N2 or N2O) to the atmosphere. When POC is the predominant form of OC in streams, how POC influences NO3− reduction within a HZ remains unclear. We established a new reactive transport model incorporating POC transport and filtration processes to assess how POC deposition affects NO3− removal. Sediment permeability decreases as POC is filtrated in the streambed. Nitrate influx is reduced due to POC‐induced sediment clogging. The deposited POC in the shallow streambed serves as an OC source and supports higher biogeochemical reaction kinetics because OC is an important substrate promoting microbial activities. The filtrated POC pool enhances denitrification, thus causing a higher NO3− removal efficiency. In contrast, the POC pool is typically assumed to be distributed homogeneously in sediments, potentially causing a significant underestimation of stream‐borne NO3− removal. A lower hydraulic conductivity, a smaller POC grain size, and a larger POC filtration efficiency and in‐stream POC concentration allow for extensive POC deposition within the shallow streambed that favors nitrate removal. This study provides a better understanding of N processing and an accurate estimation of NO3− removal potential in HZs.
A Theoretical Model of Soil Freezing Characteristic Curve Considering the Freezing of Adsorbed Water and Capillary Water
Authors: Wang Yijie , Hu Liming 
Published: July 2023

AbstractThe soil freezing characteristic curve (SFCC) represents the constitutive relationship between sub‐zero temperature and unfrozen water content in soil. It governs the hydrologic and mechanical behaviors associated with freezing soil. Numerous studies have investigated the mechanisms of soil water freezing and attempted to predict SFCC using soil water characteristic curve (SWCC) and Clapeyron equation. However, limited attention has been given to the physical disparities between adsorbed and capillary water during freezing, including variations in pressures and water‐ice interfaces. In this study, we present a novel theoretical model for predicting SFCC. The model determines the freezing point by calculating the chemical potential of soil water and ice with their respective pressures, thus capturing the distinctions in freezing behaviors between adsorbed and capillary water. All model parameters possess clear physical interpretations, and the model solely relies on the SWCC as input. The validity of the proposed model was confirmed through experimental measurements involving the water phase diagram, SWCCs, and the corresponding SFCCs of sandy, silty, and clayey soils. The model exhibits strong capabilities in predicting SFCC regardless of the soil type and outperforms the conventional method in predicting the SFCC of soil with high adsorbed water content. Model analyses were performed to investigate the effects of individual pore size, soil type, and initial water content on the freezing process, revealing the distinct contributions of adsorption and capillarity in soil water freezing. This study elucidates the mechanisms underlying soil water freezing, offering a theoretical framework for the analysis and prediction of frozen soil behaviors.
A Novel Methodology for the Stochastic Integration of Geophysical and Hydrogeological Data in Geologically Consistent Models
Authors: Neven Alexis , Renard Philippe 
Published: July 2023

AbstractTo address groundwater issues, it is often necessary to develop geological and hydrogeological models. Combining geological, geophysical and hydrogeological data available on a site to build such models is often a challenge. This paper presents a methodology to integrate such data within a geologically consistent model with robust error estimation. The methodology combines the Ensemble Smoother with Multiple Data Assimilation (ESMDA) algorithm with a hierarchical geological modeling approach (ArchPy). Geophysical and hydrogeological field data are jointly assimilated in a stochastic ESMDA framework. To speed up the inversion process, forward responses are computed in lower‐dimensional spaces relevant to each physical problem. By doing so, the final models take into account multiple data sources and regional conceptual geological knowledge. This study illustrates the applicability of this novel approach using actual data from the upper Aare Valley, Switzerland. The results of cross‐validation show that the combination of different data types, each sensitive to different spatial dimensions, enhances the quality of the model within a reasonable computing time. The proposed methodology allows the automatic generation of groundwater models with robust uncertainty estimation and could be applied to a wide variety of hydrogeological issues.
