AbstractStable isotope-based dietary information on the tenth century CE Hungarian population serves as a valuable comparative tool to other dietary stable isotope studies in the region. This study presents a multiproxy approach involving skeletal samples with the least diagenetic alteration and the best-preserved primary signals. Dental and bone samples collected from three cemeteries in northeastern Hungary were investigated using a combination of Fourier-transform infrared spectroscopy (FTIR), stable isotope geochemistry, and strontium isotope analysis. FTIR measurements were used to detect the addition of secondary carbonate to the skeletal apatite carbonate component and to differentiate diagenetically altered samples. Our results suggest that all but the bone apatite carbonate stable isotope values and87Sr/86Sr ratios are trustworthy and may be used to interpret the diet and migration of the researched individuals. We also determined that the inhabitants of the three tenth century CE Hungarian settlements relied primarily on C3plants, but that C4plants, most likely broomcorn millet (P. miliaceum), comprised a moderate portion of their plant-based diet and that animal products were generally consumed in moderate-high amounts. Coupled analyses of carbonate oxygen and strontium isotope compositions revealed that most of the bone apatite carbonate was heavily altered, whereas enamel apatite carbonate samples largely preserved their primary compositions. The bones showing the least amount of diagenetic alteration may partially preserve their primary apatite carbonate compositions, as well as show a combination of primary and secondary signals, which should be taken into consideration when bone apatite carbonate data are interpreted.

AbstractWe examined the chemical constitution of the red alga Laurencia saitoi Perestenko, collected from Katsuura, Boso Peninsula, Chiba Prefecture, Japan. This specimen produced a new polyhalogenated acetogenin, named katsuurallene (1), which structure was determined by the spectral methods, along with known diterpene, deoxyparguerol (2) and triterpene, thyrsiferol (3). In this paper we describe the structural elucidation of katsuurallene together with some biological activities.
Being, Presence, and Implication in Heidegger's Critique of Hegel
Authors: Trisokkas Ioannis 
Published: March 2022

AbstractFor Heidegger, Hegel understands being, ‘the highest actuality’, as the categories which pervade and thereby form all objects and events. Since, Heidegger argues, the categories are, in Hegel, present-at-hand, Hegel conceives of being as presence-at-hand. This is a problem, for Heidegger, because it entails the full transparency and knowability of being, whereas, in his view, being is partially hidden and unknowable. I consider the objection to this Heideggerian critique of Hegel that Hegelian logic understands being not only as the list of categories but also as their derivation and movement from pure being to the absolute idea, which (derivation and movement) establish being not only as presence but also as implication. Since being-as-implication is (a) not presence-at-hand and (b) necessary to being, it cannot be said that Hegel's account of being turns it into full transparency and knowability. Heidegger's critique should, therefore, be rejected. I argue that this objection is unsuccessful because there is strong evidence in the Logic that Hegel ‘subordinates’ being-as-implication to presence-at-hand. Implication's way of being is, in Hegel, only a collapse into presence-at-hand and hence ‘merely a modification of presence’. Consequently, Heidegger's critique of Hegel should not be rejected based on the objection. I conclude the article with a remark on the relation between language and being-as-implication. I argue that Hegel's account of being-as-implication in language disrespects the autonomy of being-as-implication therein and that Haas's argument for such an autonomy based on the phenomenon of the syntactic ellipsis of ‘is’ fails to undermine Hegel's account.
Bergson et la logique
Authors: Dalissier Michel 
Published: March 2022

RésuméJ'analyse la façon dont Bergson caractérise la logique tel un organe de simplification, de dissimulation, d'ordonnance, de limitation, de systématisation, comme habitude de pensée et comme ontologie foncière. Partout, la logique semble la prérogative de l'entendement et inapte à s'appliquer à la durée, voire à la réalité elle-même. Pour sortir d'un tel dualisme, je montre que Bergson conçoit une logique de l'absurde et de l'imagination, avec le rêve, la folie et le comique, laquelle transmute la logique dans le domaine du pathologique et de l'art littéraire, et offre à l'image une seconde gloire.
Anthropologie du pouvoir et généalogie de l’État. Deleuze et Guattari, lecteurs d'Ibn Khaldûn et de Clastres
Authors: Molino-Machetto Cédric 
Published: March 2022

RésuméComment concevoir la généalogie de l’État sans réduire les sociétés tribales au statut d'ancêtres des sociétés étatiques ? À travers cette question, c'est la généalogie du pouvoir politique qui est en jeu. Chez Ibn Khaldûn, le pouvoir fait partie intégrante d'une ontologie qui ancre le politique dans le biologique. Lorsque Gilles Deleuze et Félix Guattari butent sur la séparation radicale entre les sociétés à État et sans État chez Pierre Clastres, ils empruntent à Ibn Khaldûn le concept d'esprit de corps qui leur permet de poser la relation entre les États et leur dehors. Il s'agira pour nous de dégager une anthropologie du pouvoir chez Ibn Khaldûn afin de mieux comprendre le rôle qu'il joue dans Mille Plateaux de Deleuze et Guattari.
Women Labour Models and Socialist Transformation in early 1950s China
Authors: Spakowski Nicola 
Published: March 2022

AbstractThis article investigates Chinese women labour models (or labour heroines) of the early 1950s as actors and symbols of socialist transformation. It centres on the example of Shen Jilan (1929–2020), who was one of the most prominent women labour models of the time. Shen rose to fame through her struggle for equal pay for equal work in her native village, became a delegate to China's National People's Congress, and even participated in the Third World Congress of Women in Copenhagen in 1953. The article critically engages with the concept of “state feminism” and proposes a shift in focus from state–society relations to work as a means to understanding the transformation of women's lives under socialism. Socialist society was a society of producers and work shaped people's daily lives; it was central to identity formation and constituted the regulating mechanism of social relations. Indeed, women labour models, together with related categories of working women, came to typify the new Chinese woman, who was integral to and symbolic of socialist modernity. They epitomized communist theory about women's participation in production being the mechanism of their liberation. The article has three main parts, each of which addresses a different level (local, national, international), different constellations of actors and agency, and different aspects of the relationship between working women and socialist transformation. By tracing Shen Jilan's activities in various contexts, the article reveals the complexity, contradictions, multilayered nature, and also incompleteness of socialist transformation.
International Solidarity as the Cornerstone of the Hungarian Post-War Socialist Women's Rights Agenda in the Magazine Asszonyok
Authors: Lóránd Zsófia 
Published: March 2022

AbstractThis article analyses five years of the magazine Asszonyok (Women) the main forum for discussing women's rights between 1945 and 1949 in Hungary. The magazine was published by the Magyar Nők Demokratikus Szövetsége (the Hungarian Women's Democratic Federation), an umbrella organization created mostly by women from the communist movement. This analysis is centred around the idea of internationalism and how it became a means for socialist women's emancipation, proof of the political power of the new women's organization, and a platform of political education. It also symbolized the new era of peace after the war, peace becoming one of the slogans of the socialist women's movement globally. The broadening international platform of transfers became a terrain where political languages about race, class, and gender were slowly but steadily taking shape. Solidarity with women across the globe became one of the main tenets of communist women in Hungary. However, solidarity had its limits. As is shown here, identification with the right political agenda was even more important than aspects of race and class. This was one of the most important ways in which socialist women's rights and feminism were diverging from each other, despite the broad spectrum of shared elements on their agenda.
Speed and Expertise in Stock Picking: Older, Slower, and Wiser?

AbstractThere are significant differences among sell-side analysts in how frequently they revise recommendations. We show that much of this variation is an analyst-individual trait. Analysts who change recommendations more slowly make recommendations that are more influential and generate better portfolio returns. Slower-revising analysts tend to change recommendations following corporate news that are harder to interpret by nonstock experts, and our evidence suggests that their investment value derives from their ability to better interpret hard-to-assess information. On average, analysts change recommendations less frequently as their career progresses; however, recommendation speed-style is the dominant predictor of their recommendation value.
Specific fear of vomiting (SPOV) in early parenthood: assessment and treatment considerations with two illustrative cases
Authors: Orme Kimberly , Challacombe Fiona L. , Roxborough Alexa 
Published: March 2022

Abstract
Specific phobia of vomiting (SPOV) can be a severe and debilitating anxiety disorder and affects women in the childbearing years. The perinatal period and early parenthood is a time of increased risk for the onset or exacerbation of anxiety problems, which can have an impact on both the woman and the developing child. There are particular issues pertinent to the physical experience of pregnancy and tasks of early caregiving that women with SPOV may find difficult or distressing to confront, but these are not well documented. Cognitive behavioural therapy (CBT) focused on exposure to vomit cues and processing distressing early memories of vomiting is an effective treatment for SPOV. This paper describes the successful CBT treatment of two young mothers with SPOV, outlining the challenges faced by parents at this time and the need to take this into account in treatment, using illustrative case material.

AbstractAcetolactate synthase (ALS) inhibitors provide postemergence control of green kyllinga (Kyllinga brevifolia Rottb.) in turfgrass and other cropping systems. A suspected resistant (R) biotype of K. brevifolia was collected from a golf course and evaluated for resistance to ALS inhibitors. In greenhouse experiments, the sulfosulfuron rates required to cause 50% shoot biomass reduction from the nontreated at 4 wk after treatment (WAT) were 10 and 792 g ai ha−1 for the susceptible (S) and R biotypes, respectively. The rates required to cause 50% injury at 4 WAT were 189 and >3,360 g ai ha−1, respectively. In other experiments, shoot mass of the R biotype was not reduced by imazaquin, trifloxysulfuron-sodium, pyrimisulfan, thiencarbazone + foramsulfuron + halosulfuron, florasulam + halauxifen-methyl, and bentazon compared with the nontreated, while sulfentrazone reduced biomass similarly for both R and S biotypes. Gene sequencing of the R biotype revealed a mutation at Asp-376-Glu that has previously conferred resistance to five families of ALS inhibitors. This is the first report of ALS-inhibitor resistance in K. brevifolia.
Planetary Waves Controlling the Effect of Energetic Electron Precipitation on the Northern Polar Vortex
Authors: Salminen Antti , Asikainen Timo , Mursula Kalevi 
Published: March 2022

AbstractEnergetic electron precipitation (EEP) forms ozone‐depleting nitrogen and hydrogen oxides in the high‐latitude middle and upper atmosphere, leading to ozone destruction and temperature enhancement that can strengthen the winter polar vortex. This EEP effect on polar vortex depends on quasi‐biennial oscillation and sudden stratospheric warmings, which earlier studies relate to planetary waves. We study here the possible modulation of the EEP effect by planetary waves. We perform a principal component analysis of the vertical component of Eliassen‐Palm flux (EP flux) to examine the latitudinal pattern of planetary waves. We use a multilinear regression analysis to estimate the responses of zonal wind and EP flux divergence to EEP in the northern winter stratosphere by keeping the two leading principal components of vertical EP flux as controlling factors. We find that the EEP strengthens the polar vortex most systematically when planetary wave propagation is enhanced at mid‐latitudes but reduced at polar latitudes.

AbstractFlux enhancements of field‐aligned low‐energy O+ ion (FALEO) are simultaneously observed by Arase, Van Allen Probes A and B in the nightside inner magnetosphere during 05–07 UT on September 22, 2018. FALEOs appear after a magnetic dipolarization signature with approximately 6–20 min delay. It has the energy‐dispersion signature from a few keV to ∼100 eV only in the direction parallel to the magnetic field at Arase, while it decreases its energy from a few keV down to 10 eV in both the parallel and antiparallel directions at Probes A and B. We perform a numerical simulation to trace trajectories of test O+ ions in a model magnetosphere, which are launched from above the ionosphere 3–15 min after a substorm. Flying virtual satellites that have the same orbits as the real satellites, we create virtual energy‐time spectrograms of O+ ions to compare with the observed ones. Results show a very good correspondence between them, indicating that FALEOs originate from ionospheric O+ ions that are extracted from the upper ionosphere at substorm onset and flow along the magnetic field toward the geomagnetic equator. It is also revealed that 3–9 hr after their launch, test O+ ions less than 400 eV have a spatial distribution in the inner magnetosphere which is similar to those of the warm plasma cloak and the oxygen torus. We therefore conclude that FALEO is a source of those cold ion populations.
Effects of Fracture Connectivity on Rayleigh Wave Dispersion

Published: March 2022

AbstractPassive seismic characterization is an environmentally friendly method to estimate the seismic properties of the subsurface. Among its applications, we find the monitoring of geothermal reservoirs. One key characteristic to ensure a productive management of these reservoirs is the degree of fracture connectivity and its evolution, as it affects the flow of fluids within the formation. In this work, we explore the effects of fracture connectivity on Rayleigh wave velocity dispersion accounting for wave‐induced fluid pressure diffusion (FPD) effects. To this end, we consider a stratified reservoir model with a fractured water‐bearing formation. For the stochastic fracture network prevailing in this formation, we consider varying levels of fracture density and connectivity. A numerical upscaling procedure that accounts for FPD effects is employed to determine the corresponding body wave velocities. We use a Monte‐Carlo‐type approach to obtain these velocities and incorporate them in the considered fractured reservoir model to assess the sensitivity of Rayleigh wave velocity dispersion to fracture connectivity. Our results show that Rayleigh wave phase and group velocities exhibit a significant sensitivity to the degree of fracture connectivity, which is mainly due to a reduction of the stiffening effect of the fluid residing in connected fractures in response to wave‐induced FPD. These effects cannot be accounted for by classical elastic approaches. This suggests that Rayleigh wave velocity changes, which are commonly associated with changes in fracture density, may also be related to changes in interconnectivity of pre‐existing or newly generated fractures.
Decadal Variation and Regulation Mechanisms of the Suspended Sediment Concentration in the Bohai Sea, China

Published: March 2022

AbstractBohai Sea, with the highest suspended sediment concentration in the world, has experienced a sharp decrease in sea surface suspended sediment concentration (SSSC) in the latest two decades. However, limited by the shortage of long‐term field observations, the spatiotemporal characteristics and mechanisms of the long‐term variation in the SSSC are still unclear. Based on remote sensing data, this study reconstructed the spatiotemporal SSSC distribution from 2003 to 2016, and found significant spatial difference in decadal SSSC variation in the Bohai Sea. The largest decadal SSSC decrease was observed in the southern Bohai Sea with an average annual decrease of 1.3 mg/L (decrease of 4.4% per year), while significant SSSC increase was observed in the central Bohai Sea with largest annual increase of 0.4 mg/L (increase of 5.0% per year). Significant seasonal differences in the SSSC decreasing were also revealed, and the SSSC decrease in winter and spring (0.46 mg/L/a) was 27.8% higher than that in summer and autumn (0.36 mg/L/a). Decadal wind speed data measured at 14 meteorological stations around the Bohai Sea indicated that wind speed reduction played the most important role in the decadal decrease in SSSCs, and significant SSSC decrease can only be found in sea areas with a significantly reduced wind speed. In addition, although the runoff and sediment discharge of the Yellow River also decreased during 2003–2016, they were not related to the spatiotemporal variation of SSSCs and their direct impact was limited to the range of 15 km from the estuary.
Impact of Inter‐Utility Agreements on Cooperative Regional Water Infrastructure Investment and Management Pathways

Published: March 2022

AbstractUrban water utilities, facing rising demands and limited supply expansion options, increasingly partner with neighboring utilities to develop and operate shared infrastructure. Inter‐utility agreements can reduce costs via economies of scale and help limit environmental impacts, as substitutes for independent investments in large capital projects. However, unexpected shifts in demand growth or water availability, deviating from projections underpinning cooperative agreements, can introduce both supply and financial risk to utility partners. Risks may also be compounded by asymmetric growth in demand across partners or inflexibility of the agreement structure itself to adapt to changing conditions of supply and demand. This work explores the viability of both fixed and adjustable capacity inter‐utility cooperative agreements to mitigate regional water supply and financial risk for utilities that vary in size, growth expectations, and independent infrastructure expansion options. Agreements formalized for a shared regional water treatment plant are found to significantly improve regional supply reliability and financial outcomes, despite highly correlated weather and climate across neighboring supply systems (e.g., concurrent drought events). Regional improvements in performance, however, mask tradeoffs among individual agreement partners. Adjustable treatment capacity allocations add flexibility to inter‐utility agreements but can compound financial risk to each utility as a function of the decision‐making of the other partners. Often the sensitivity to partners' decision‐making under an adjustable agreement degrades financial performance, relative to agreements with fixed capacities allocated to each partner. Our results demonstrate the significant benefits cooperative agreements offer, providing a template to aid decision‐makers in the development of water supply partnerships.
Responses of Horizontally Expanding Oceanic Oxygen Minimum Zones to Climate Change Based on Observations

Published: March 2022

AbstractDue to climate change, global oceanic dissolved oxygen (DO) has been decreasing, and oxygen minimum zones (OMZs) have been expanding. Here, we estimate the annual global and regional OMZ areas using geostatistical regression combined with Monte Carlo. From 1960 to 2019, annual global OMZ20 (DO < 20 μmol/kg) and OMZ60 (DO < 60 μmol/kg) areas cover 5%–14% and 15%–32% of the global ocean, respectively. The global and most regional OMZ areas after the late 2000s were all significantly larger than those in previous years. Most oceanic regions likely experienced significant expansions in OMZ areas, especially the North Pacific. However, the equatorial Pacific with the largest OMZ area showed insignificant horizontal expansion. The expanding OMZ areas of most oceans responded more quickly and effectively to the surrounding sea temperatures than to the sea surface temperatures. Our research highlights the need for marine resource management to account for the challenges from OMZs.
