Are propagandists combatants? Analysing the ethical status of propagandists in warfare
Authors: Robin Marie 
Published: February 2024

AbstractBelligerents increasingly rely on media manipulation, propaganda, and communication to attain strategic advantages in conflict. Given the civilian propagandists’ clear role in creating tactical or strategic advantages for one side in the conflict, should these propagandists be considered combatants, and can they therefore be legitimately targeted because of their activities? This article overcomes traditional binary frameworks of distinction to argue that propagandists are indirectly participating civilians, i.e. participants who cannot be intentionally or directly killed in conflict. Because of their activities, propagandists, it argues, are liable to less-than-lethal harm, of which it identifies three types (destruction of property, privation of liberty, isolation). The article then proposes a necessary criterion – necessity – to decide if less-than-lethal harm is warranted against propagandists. It then creates four new criteria – denial of agency, falsehood, influence, gratification – to serve as assessment criteria able to decide what degree of harm a propagandist may maximally face. In making this argument, the article contributes to just war literature by proposing a novel way to evaluate the ethical status of a highly diverse, yet undoubtedly influential, category of war participants: those who undertake the ‘media battle’, outside of the military.
Elevated litterfall phosphorus reduces litter and soil organic matter pools in exotic-dominated novel forests in Singapore

Published: February 2024

AbstractThe estimation of leaf litter turnover is often limited to early-stage decomposition using unrepresentative models and litter types. In tropical secondary forests, particularly exotic-dominated novel forests, the characterisation of litter turnover remains poor. This study estimated the annual turnover ofin-situleaf litter across four forest successional types in Singapore using a Weibull residence time model. Litter turnover and nutrient dynamics diverged between young secondary and old-growth forests. In particular, within novel forests, annual phosphorus return via leaf litterfall was three times that of primary forests, while the mass loss ofin-situleaf litter was highest among all forest successional types, estimated at 92.8% annually with a mean residence time of 176 days, resulting in a litter pool size a third that of primary forests. Our findings suggest that tree species composition and species-specific effects shaped the observed variations in litter turnover and nutrient dynamics across forest successional types and forest stands, whereas tree species richness, canopy structure, soil nutrient levels, and microclimate were found to be non-predictors. Taken together, our study provides an insight into litter turnover in human-modified tropical landscapes increasingly characterised by novel forests, potentially leading to a reduction in surface litter and soil organic carbon pools.
Autonomous multicopter landing on a moving vehicle based on RSSI

Published: February 2024

AbstractCurrently, most of the studies on unmanned aerial vehicle (UAV) automatic landing systems mainly depend on image information to determine the landing location. However, the system requires a camera, a gimbal system and a separate image-processing device, which increases the weight and power consumption of the UAV, resulting in a shorter flight time. In addition, a large amount of computation and slow reaction speed can cause the camera to miss a proper landing moment. To solve these problems, in this study, the moving direction and relative distance between an object and the automatic landing system were measured using a receive signal strength indicator of the radio-frequency (RF) signal. To improve the movement direction and relative distance estimation accuracy, the noise in the RF signal was minimised using a low pass filter and moving average filter. Based on the filtered RF signal, the acceleration of the multicopter to reach the object was estimated by adopting the proportional navigation algorithm. The performance of the proposed algorithm for precise landing on a moving vehicle was demonstrated through experiments.

Abstract
Mollusc and crustacean consumption in the first 1000 d may improve maternal and child health by providing essential nutrients. However, in some contexts, molluscs and crustaceans have been associated with allergies and environmental contamination, potentially leading to adverse health and development outcomes. It is unclear whether the health benefits of consuming molluscs and crustaceans, collectively classified as shellfish in nutrition, are outweighed by the potential risks to pregnant women and children. We conducted a scoping review (PROSPERO: CRD42022320454) in PubMed, Scopus and EBSCO Global Health of articles published between January 2000 and March 2022 that assessed shellfish consumption during pregnancy, lactation or childhood (0–2 years) in relation to maternal health, child health or child development. A total of forty-six articles were included in this review. Overall, shellfish consumption was associated with higher biomarkers of environmental contaminants, with mercury being the most studied and having the strongest evidence base. The limited research on nutritional biomarker status shows an association between shellfish consumption and iodine status. Preterm birth was not associated with shellfish consumption, but newborn anthropometry showed mixed results, with several studies reporting lower birth weight with higher shellfish consumption. The few studies that examined child development and maternal health outcomes reported no significant associations. This review revealed trade-off health risks and benefits with inclusion of molluscs and crustaceans in the dietary patterns of mothers and young children. More research is needed to understand how these aquatic animal-source foods may be safely consumed and leveraged for improving human nutrition.
Language contexts induced by the interlocutors’ proficiencies modulate bilingual language monitoring

Published: February 2024

Abstract
Using a voluntary object-naming paradigm, we examined if bilinguals with high or low L2 proficiency monitor their language selection and production according to their interlocutors' L2 language proficiency. Telugu (L1)–English (L2) bilinguals were introduced to audio-visual stimuli that consisted of animated interlocutors that were high or low proficient in English. In Experiment 1, interlocutors were presented at different frequencies in each block, and in Experiment 2, the presentation of each interlocutor was blocked. We predicted that the frequency of interlocutors would modulate language activation and selection. The participants named the objects language that came to their minds to respond to interlocutors. Indeed, consistent with our predictions, monitoring contexts induced by such interlocutors influenced latencies, language choice and switch-cost. High-L2 proficient participants employed higher language control than low-L2 proficient participants. These results support the hypothesis that bilinguals are sensitive toward their interlocutors' language proficiency and employ context-appropriate cognitive control.
LGB+ identity and its implications for the policy positions of parliamentary candidates
Authors: Debus Marc , Wurthmann L. Constantin 
Published: February 2024

AbstractSeveral studies concentrate on the representation of minority groups and the policy goals that members of these groups highlight when becoming candidates for public offices. However, we do not know much about the degree of parliamentary representation of sexual minorities and what ideological profile politicians with an LGB+ identity adopt. We aim at filling this gap by analysing the ideological stances of LGB+ candidates on key policy dimensions. Using data from the 2021 German candidate study, we find that the self-identification as LGB+ contributes significantly to adopting progressive stances on the socio-cultural dimension and more favourable positions on welfare state expansion, regardless of further important factors like party affiliation. Moreover, candidates who consider themselves LGB+ do take on significantly less traditional positions on the socio-cultural dimension compared to the position of their party, indicating that increasing descriptive representation of LGB+ individuals in parliament leads to a strengthening of more progressive voices in parliament and a stronger substantive representation of LGB+ interests.
Control of giant ragweed (Ambrosia trifida) in mesotrione-resistant soybean

Published: February 2024

Abstract
Preemergence applications of mesotrione, an herbicide that inhibits 4-hydroxyphenolpyruvate dioxygenase (HPPD), have recently gained regulatory approval in soybean varieties with appropriate traits. Giant ragweed is an extremely competitive broadleaf weed, and biotypes resistant to acetolactate synthase inhibitors (ALS-R) can be particularly difficult to manage with soil-residual herbicides in soybean production. This study investigated control of giant ragweed from preemergence applications of cloransulam (32 g ai ha–1), metribuzin (315 g ai ha–1), and S-metolachlor (1,600 g ai ha–1) in a factorial design with and without mesotrione (177 g ai ha–1) at two different sites over 2 yr. Treatments with mesotrione were also compared with two commercial premix products: sulfentrazone (283 g ai ha–1) and cloransulam (37 g ai ha–1), and chlorimuron (19 g ai ha–1), flumioxazin (69 g ai ha–1), and pyroxasulfone (87 g ai ha–1). At 42 d after planting, control and biomass reduction of giant ragweed were greater in treatments with mesotrione than any treatment without mesotrione. Giant ragweed biomass was reduced by 84% in treatments with mesotrione, whereas treatments without mesotrione did not reduce biomass relative to the nontreated. Following these preemergence applications, sequential herbicide treatments utilizing postemergence applications of glufosinate (655 g ai ha–1) plus fomesafen (266 g ai ha–1) and S-metolachlor (1,217 g ai ha–1) resulted in at least 97% control of giant ragweed at 42 d after planting, which was greater than sequential applications of glufosinate alone in 3 of 4 site-years. Preemergence applications of mesotrione can be an impactful addition to soybean herbicide programs designed to manage giant ragweed, with the potential to improve weed control and delay the onset of herbicide resistance by providing an additional effective herbicide site of action.

Abstract
Rice in Mississippi is often in early seedling growth stages when paraquat-based herbicide treatments are commonly applied to corn, cotton, and soybean; therefore, off-target movement of the herbicide onto adjacent rice fields may occur. After an off-target movement event has occurred, weed management in the rice crop is still necessary. Field studies were conducted from 2019 to 2021 in Stoneville, MS, to evaluate rice injury and barnyardgrass control with labeled herbicides after exposure to a sublethal concentration of paraquat. Herbicide treatments were label-recommended rates of imazethapyr, quinclorac, propanil, bispyribac-sodium, cyhalopfop, and florpyrauxifen-benzyl applied following rice exposure to a sublethal concentration of paraquat. Rice injury was detected 7 and 28 d after treatment (DAT) and was ≥35% and ≥14%, respectively, for all herbicides. Florpyrauxifen-benzyl and imazethapyr caused the greatest rice injury at 28 DAT. Following paraquat exposure, barnyardgrass control was similar for all labeled herbicide treatments at 7, 14, and 28 DAT except for florpyrauxifen-benzyl and no herbicide (paraquat alone) at 7 DAT. Across all evaluations, barnyardgrass control was at least 12% greater following paraquat exposure and labeled herbicide treatments than with no paraquat exposure. The current research demonstrates that labeled rates of herbicides applied following exposure to a sublethal concentration of paraquat resulted in <36% injury and provided as great as 95% control of barnyardgrass, depending on the herbicide treatment. Therefore, the labeled herbicides choice following rice exposure to a sublethal concentration of paraquat should be based on weed spectrum.

AbstractQuinclorac controls crabgrass (Digitaria spp.) in cool- and warm-season turfgrass species. Herbicide-resistant smooth crabgrass [Digitaria ischaemum (Schreb.) Schreb. ex Muhl.] biotypes have evolved due to recurrent usage of quinclorac. Two Mississippi populations (MSU1 and MSU2) of D. ischaemum were characterized using standard greenhouse dose–response screens to assess their resistance relative to known susceptible populations. Subsequent investigations explored mechanisms of resistance, including examining cyanide accumulation, glutathione S-transferase (GST) activity, and the potential involvement of cytochrome P450s in MSU1, MSU2, and a susceptible (SMT2). Resistant populations MSU1 and MSU2 required 80 and 5 times more quinclorac, respectively, to reach 50% biomass reduction than susceptible populations. The SMT2 biotype accumulated three times more cyanide than the resistant MSU1 and MSU2 populations. GST activity was elevated in resistant MSU1 and MSU2 populations. Furthermore, quinclorac concentrations in treated resistant populations were elevated when plants were pretreated with the P450 inhibitor malathion. These findings suggest a non–target site based mechanism of resistance involving the accumulation of cyanide. This may provide a scientific basis for understanding the occurrence of quinclorac-resistant D. ischaemum, although further research is needed to investigate potential target-site mechanisms of resistance.
A History of Chinese Musical Instrument Education in Toronto
Authors: CUI YAO 
Published: February 2024

AbstractWhereas students in China can take Chinese instrument training in a variety of settings, Canada has no systematized structure of Chinese music education. Indeed, little scholarly attention has been paid to the development of Chinese instrumental music education in the Chinese diaspora within North America. Based on extensive fieldwork in Toronto, I address the following questions in this article: How do Chinese immigrants pass down their music? How and where do students take Chinese instrument training? How have the methods of transmission evolved? And how do Chinese instrument pedagogical techniques bridge Chinese and Canadian contexts?
Water Market Functionality: Evidence From the Australian Experience

Published: February 2024

AbstractMarket approaches to natural resource management have gained popularity over the last few decades. This study provides an encompassing analysis of the water market in the southern Murray‐Darling Basin (sMDB), Australia, in order to evaluate its performance and the importance of having various types of water rights traded in the market. We do so by investigating a set of market attributes, including price and price volatility, traded volume, number and the average size of transactions, and net import across a number of trading zones in the southern Murray‐Darling Basin. Our findings show that the price mechanism in the water market functions as intended, as the water prices signal the level of scarcity and reflect value that can be derived from water resources. Other factors like crop structure and institutional settings also play important roles in explaining differences in water market outcomes across the considered trading zones within the sMDB market. Overall, our findings document that water markets serve well their fundamental purpose in water resource management to allocate water toward its economically‐highest‐valued uses, and that various types of water rights traded in the market are meeting heterogenous needs of market participants in managing water supply and use.
2D Near‐Surface Full‐Waveform Tomography Reveals Bedrock Controls on Critical Zone Architecture

Published: February 2024

AbstractFor decades, seismic imaging methods have been used to study the critical zone, Earth's thin, life‐supporting skin. The vast majority of critical zone seismic studies use traveltime tomography, which poorly resolves heterogeneity at many scales relevant to near‐surface processes, therefore limiting progress in critical zone science. Full‐waveform tomography can overcome this limitation by leveraging more seismic data and enhancing the resolution of geophysical imaging. In this study, we apply 2D full‐waveform tomography to match the phases of observed seismograms and elucidate previously undetected heterogeneity in the critical zone at a well‐studied catchment in the Laramie Range, Wyoming. In contrast to traveltime tomograms from the same data set, our results show variations in depth to bedrock ranging from 5 to 60 m over lateral scales of just tens of meters and image steep low‐velocity anomalies suggesting hydrologic pathways into the deep critical zone. Our results also show that areas with thick fractured bedrock layers correspond to zones of slightly lower velocities in the deep bedrock, while zones of high bedrock velocity correspond to sharp vertical transitions from bedrock to saprolite. By corroborating these findings with borehole imagery, we hypothesize that lateral changes in bedrock fracture density majorly impact critical zone architecture. Borehole data also show that our full‐waveform tomography results agree significantly better with velocity logs than previously published traveltime tomography models. Full‐waveform tomography thus appears unprecedentedly capable of imaging the spatially complex porosity structure crucial to critical zone hydrology and processes.
Toward a US Framework for Continuity of Satellite Observations of Earth's Climate and for Supporting Societal Resilience
Authors:   KISS Continuity Study Team
Published: February 2024

AbstractThere is growing urgency for improved public and commercial services to support a resilient, secure, and thriving United States (US) in the face of mounting decision‐support needs for environmental stewardship and hazard response, as well as for climate change adaptation and mitigation. Sustained space‐based Earth observations are critical infrastructure to support the delivery of science and decision‐support information with local, national, and global utility. This is reflected in part through the United States' sustained support of a suite of weather and land‐imaging satellites. However, outside of these two areas, the US lacks an overarching, systematic plan or framework to identify, prioritize, fund, and implement sustained space‐based Earth observations to meet the Nation's full range of needs for science, government policy, and societal support. To aid and accelerate the discussion on our nation's needs, challenges and opportunities associated with sustained critical space‐based Earth observations, the Keck Institute for Space Studies (KISS) sponsored a multi‐week think‐tank study to offer ways forward. Based on this study, the KISS study team suggests the establishment of a robust coordination framework to help address US needs for sustained Earth observations. This coordination framework could account for: (a) approaches to identify and prioritize satellite observations needed to meet US needs for science and services, (b) the rapidly evolving landscape of space‐based Earth viewing architecture options and technology improvements with increasing opportunities and lower cost access to space, and (c) the technical and programmatic underpinnings required for proper and comprehensive data stewardship to support a wide range of research and public services.
Climate Change Will Impact Surface Water Extents and Dynamics Across the Central United States

Published: February 2024

AbstractClimate change is projected to impact river, lake, and wetland hydrology, with global implications for the condition and productivity of aquatic ecosystems. We integrated Sentinel‐1 and Sentinel‐2 based algorithms to track monthly surface water extent (2017–2021) for 32 sites across the central United States (U.S.). Median surface water extent was highly variable across sites, ranging from 3.9% to 45.1% of a site. To account for landscape‐based differences (e.g., water storage capacity, land use) in the response of surface water extents to meteorological conditions, individual statistical models were developed for each site. Future changes to climate were defined as the difference between 2006–2025 and 2061–2080 using MACA‐CMIP5 (MACAv2‐METDATA) Global Circulation Models. Time series of climate change adjusted surface water extents were projected. Annually, 19 of the 32 sites under RCP4.5 and 22 of the 32 sites under RCP8.5 were projected to show an average decline in surface water extent, with drying most consistent across the southeast central, southwest central, and midwest central U.S. Projected declines under surface water dry conditions at these sites suggest greater impacts of drought events are likely in the future. Projected changes were seasonally variable, with the greatest decline in surface water extent expected in summer and fall seasons. In contrast, many north central sites showed a projected increase in surface water in most seasons, relative to the 2017–2021 period, likely attributable to projected increases in winter and spring precipitation exceeding increases in projected temperature.
