“The human face of the UN plastics treaty”? The role of waste pickers in intergovernmental negotiations to end plastic pollution and ensure a just transition
Authors: O’Hare Patrick , Nøklebye Emmy 
Published: April 2024

Abstract
Waste pickers are recognised as a key stakeholder in the ongoing negotiations towards an international legally binding instrument to end plastic pollution. Up to 34 million waste pickers contribute to recovering close to 60% of recycled post-consumer plastic waste globally. The International Alliance of Waste Pickers (IAWP) has actively engaged in the negotiations to safeguard a just transition for these important but vulnerable and frequently overlooked workers. This article explores how the IAWP has gained prominence in the plastics treaty negotiations through three iterative processes. First, the reiterative naming of “waste pickers” has constituted a symbolic practice and discursive influence that heightened recognition of waste pickers’ role as knowledge and rights holders in a just transition to end plastic pollution. Second, the performative dimension of waste picker advocacy has influenced official and informal events. Third, by engaging in “scale work”, waste pickers have influenced and leveraged their alliances to work towards a just transition across national, regional and international levels. By examining the role and influence of waste pickers in the plastics treaty through the frames of naming, performance and scale, the article contributes to advance the scholarly literature on just transition and grassroots movements in global environmental governance (GEG).

AbstractMicroRNAs (miRNAs) have emerged as important regulators of lipid metabolism. Recent studies have suggested synbiotics may modulate miRNA expression and lipid metabolism. This study aimed to investigate the effects of synbiotic supplementation on circulating miR-27a, miR-33a and lipid parameters in patients with dyslipidaemia. Fifty-six eligible participants were randomly allocated to receive either synbiotic or placebo sachets twice a day for 12 weeks. Each synbiotic sachet contained 3 × 1010 colony forming unit six species of probiotic microorganisms and 5 g of inulin and fructooligosaccharide as prebiotics. Serum miR-27a and miR-33a expression levels, serum lipids and apolipoproteins, the fecal concentration of short-chain fatty acids (SCFA) and Firmicutes and Bacteroidetes phyla were assessed before and after the study. Real-time PCR was used to determine the relative expression levels of miRNAs. The results showed synbiotic supplementation significantly downregulated the expression levels of miR-27a and miR-33a compared with the placebo group (P = 0·008 and P = 0·001, respectively). Furthermore, the intervention group exhibited significant improvements in serum HDL-cholesterol, small dense LDL (sdLDL-cholesterol), apoA-I and apoB-100 (P = 0·008, P = 0·006, P = 0·003, P = 0·001, respectively). The results showed a significant negative correlation between miR-33a expression levels with HDL-cholesterol, butyrate, propionate and a significant positive correlation with total cholesterol, LDL-cholesterol and sdLDL-cholesterol in the intervention group. Fecal bacteria and SCFA were significantly increased in the intervention group. This study provides evidence that synbiotic supplementation can modulate miR-27a and miR-33a expression and improve lipid metabolism in patients with dyslipidaemia.
Bound by Borders: Voter Mobilization Through Social Networks

Published: April 2024

AbstractA vast and growing quantitative literature considers how social networks shape political mobilization but the degree to which turnout decisions are strategic remains ambiguous. Unlike previous studies, we establish personal links between voters and candidates and exploit discontinuous incentives to mobilize across district boundaries to estimate causal effects. Considering three types of networks – families, co-workers, and immigrant communities – we show that a group member's candidacy acts as a mobilizational impulse propagating through the group's network. In family networks, some of this impulse is non-strategic, surviving past district boundaries. However, the bulk of family mobilization is bound by the candidate's district boundary, as is the entirety of the mobilizational effects in the other networks.
THE DEATH AND PUBLIC REHABILITATION OF APOLLINARIS THE ELDER: INTERTEXTUALITY WITH LUCAN IN SIDONIUS APOLLINARIS, EPIST. 3.12
Authors: van Waarden Joop 
Published: April 2024

AbstractSidonius Apollinaris’ Epist. 3.12 tells how one day, while leaving Lyons, he caught a couple of gravediggers about to violate his grandfather Apollinaris’ grave, which had become unrecognizable over time. He instructs the addressee, his nephew Secundus, to restore the tomb mound and provide it with a stone for which he attaches the text. Whereas this letter is usually interpreted as a piece of self-promotion by the author for his filial piety and expert storytelling, this article suggests that there is a significant subtext to be found in Lucan's Pharsalia which makes the letter first and foremost a rehabilitation of Apollinaris while strongly suggesting that the latter was executed. There follow some rather more tentative thoughts trying to grasp the precise critical moment in time for this rehabilitation. It is argued that this could be Sidonius’ departure for Clermont, in 469/470 to take on the episcopate, after his term as City Prefect of Rome and a stay in Lyons with Bishop Patiens. The letter is aimed at bolstering family cohesion in the conflict of interests between Auvergne and Provence and at securing Sidonius’ position as incumbent bishop.
An Assessment of the Doctrine of Commorientes and Its Implications for the Devolution of Testate and Intestate Property in Ghana
Authors: Hammond Ama F , Batariwah Prosper 
Published: April 2024

AbstractThe Wills Act 1971 and the Intestate Succession Act 1985 embody commorientes rules that are inconsistent, unfair to one of the deceased persons and arguably undermine the expectations of Ghanaians. While the former presumes that a testator predeceases a beneficiary, the latter presumes that the older spouse died before the younger. Though these presumptions are essential for establishing entitlement to property, it would seem that they work to the advantage of one of the parties and to the detriment of the other. Accordingly, the commorientes rules must be modified to include presumptions that are equitable and consistent with the socio-cultural expectations of Ghanaians. This can be achieved by resorting primarily to expectations regarding succession at customary law.
Construction of Il/Legitimate Migrant Labor: Non-Nationals in Domestic Service and Gardening in Interwar Austria
Authors: Richter Jessica 
Published: April 2024

AbstractLike other European countries, Austria introduced employment restrictions for foreigners after World War I. Access to the labor market was to be reserved primarily for Austrian citizens. These new regulations related exclusively to dependent employees and allowed exceptions in view of family reunification, among other things. They were based on official labor market categories and reflected widely accepted imaginations of gender-specific abilities and responsibilities. However, many foreigners earned their living in a household context and their activities hardly matched the official categories of work and family. Since decision-making on employment permits required unambiguous categorization, this situation posed a dilemma for the authorities in charge. Given the vast variety of work arrangements and relations, they struggled to clearly draw the line between “employed” and “not employed” workers. Using the example of domestic help and Bulgarian gardeners, this article investigates administrative authorities' attempts to make such distinctions and it examines migrants' efforts to occupy labor market niches. While migrants un/intentionally circumvented regulations and made their living in Austria, the ongoing disputes paradoxically contributed to an enforcement of restrictions. Administrative authorities gradually increased their endeavor to locate unauthorized foreign workers even within households and they sharpened the criteria for their categorization.
Modeling, simulations and experiments with generally routed cable-driven continuum robots and their application to three-fingered grippers
Authors: Mahapatra Soumya Kanti , Ghosal Ashitava 
Published: April 2024

AbstractThis paper deals with generally routed, pre-bent cable-driven continuum robots (CCR). A CCR consists of a flexible backbone to which multiple disks are attached. Cables are passed through holes in the disk, and when pulled, the flexible backbone and the CCR can attain different shapes based on their routing and backbone configuration. An optimization-based approach, using minimization of strain energy, is shown to give good results for the pose and motion of the CCR and to determine contact with external objects. The pose, motion, and the contact obtained from the model are shown to match very well with experimental results obtained from a 3D-printed CCR. An algorithm is proposed to generate the pre-bent backbone for a CCR which on actuation can attain the desired shape. Using the algorithm, three 3D-printed CCRs with pre-bent backbones are fabricated and these are used to demonstrate a compliant gripper that can grip a spherical object similar to that done by tentacles, and another three-fingered gripper with straight backbone CCRs is used to orient a square object gripped at the end.
A variationist study of /tʊt/ in Michif French
Authors: Bigot Davy , Papen Robert 
Published: April 2024

AbstractThis research focuses on the dissidence of Michif French, an endangered variety of Laurentian French spoken by a number of Métis in Western Canada. We examine the vernacular use of [tʊt] (tout/tous ‘all, every’) in a corpus of around 50 interviews collected in the Métis community of St. Laurent, Manitoba, in the 1980s. On the one hand, the internal analysis supports the hypothesis that it is related to the other varieties of Laurentian French. On the other hand, the external data reveal that [tʊt] is widely used, confirming the highly vernacular character of Michif French compared to the other varieties. Finally, the analysis of several interview extracts illustrates that the intensive use of vernacular variants acts as an identity marker, enabling speakers to lay claim not only to their culture, but also to a language they consider distinct from that of other French speakers.

AbstractExplaining the spatially variable impacts of flood‐generating mechanisms is a longstanding challenge in hydrology, with increasing and decreasing temporal flood trends often found in close regional proximity. Here, we develop a machine learning‐informed approach to unravel the drivers of seasonal flood magnitude and explain the spatial variability of their effects in a temperate climate. We employ 11 observed meteorological and land cover (LC) time series variables alongside 8 static catchment attributes to model flood magnitude in 1,268 catchments across Great Britain over four decades. We then perform a sensitivity analysis to assess how a 10% increase in precipitation, a 1°C rise in air temperature, or a 10 percentage point increase in urban or forest LC may affect flood magnitude in catchments with varying characteristics. Our simulations show that increasing precipitation and urbanization both tend to amplify flood magnitude significantly more in catchments with high baseflow contribution and low runoff ratio, which tend to have lower values of specific discharge on average. In contrast, rising air temperature (in the absence of changing precipitation) decreases flood magnitudes, with the largest effects in dry catchments with low baseflow index. Afforestation also tends to decrease floods more in catchments with low groundwater contribution, and in dry catchments in the summer. Our approach may be used to further disentangle the joint effects of multiple flood drivers in individual catchments.

Published: April 2024

AbstractGlobal coupled climate models are in continuous need for evaluation against independent observations to reveal systematic model deficits and uncertainties. Changes in terrestrial water storage (TWS) as measured by satellite gravimetry missions GRACE and GRACE‐FO provide valuable information on wetting and drying trends over the continents. Challenges arising from a comparison of observed and modelled water storage trends are related to gravity observations including non‐water related variations such as, for example, glacial isostatic adjustment (GIA). Therefore, correcting secular changes in the Earth's gravity field caused by ongoing GIA is important for the monitoring of long‐term changes in terrestrial water from GRACE in particular in former ice‐covered regions. By utilizing a new ensemble of 56 individual realizations of GIA signals based on perturbations of mantle viscosities and ice history, we find that many of those alternative GIA corrections change the direction of GRACE‐derived water storage trends, for example, from gaining mass into drying conditions, in particular in Eastern Canada. The change in the sign of the TWS trends subsequently impacts the conclusions drawn from using GRACE as observational basis for the evaluation of climate models as it influences the dis‐/agreement between observed and modelled wetting/drying trends. A modified GIA correction, a combined GRACE/GRACE‐FO data record extending over two decades, and a new generation of climate model experiments leads to substantially larger continental areas where wetting/drying trends currently observed by satellite missions coincide with long‐term predictions obtained from climate model experiments.
A Common Diffusional Mechanism for Creep and Grain Growth in Polymineralic Rocks: Application to Lower Mantle Viscosity Estimates
Authors: Okamoto A. , Hiraga T. 
Published: April 2024

AbstractIn a previous study (Okamoto & Hiraga, 2022, https://doi.org/10.1029/2022jb024638), we concluded that diffusion creep and grain growth in polymineralic rocks proceed by a common diffusional mechanism. Here, we built on that finding and estimated lower mantle grain size and viscosity during a single mantle convection cycle dominated by diffusion creep. We approximated the lower mantle as a two‐phase material consisting of bridgmanite + ferropericlase and post‐perovskite + ferropericlase, depending on depth. We used previously reported self‐diffusivities for bridgmanite and post‐perovskite. We predict a bridgmanite grain‐size of tens to hundreds of microns shortly after the phase transition at ∼660 km depth. This size remains relatively constant until the mantle material enters the post‐perovskite zone, which is marked by significant grain growth up to ∼9 mm just prior to upwelling. This size is sufficient to prevent further grain growth until the mantle material reaches the top of the lower mantle. These grain sizes combined with the diffusivities yield viscosities that vary laterally and with depth. At a lateral temperature difference of up to 800 K in the lower mantle, fine‐grained cold downwelling mantle is almost as viscous as, or more likely to be softer than coarse‐grained hot upwelling mantle. The lateral viscosity variations cannot be more than 2 orders of magnitude, and we estimated viscosities of 1018–1020 Pa · s in the upper lower mantle, 5 × 1020–5 × 1022 Pa · s in the lower bridgmanite zone, and 1017–1019 Pa · s in the post‐perovskite zone, which compare well with the values estimated in previous geophysical modeling studies.

AbstractDrowsiness while driving negatively impacts road safety, especially in truck drivers. The present study investigated the feasibility and alerting effects of a daylight-supplementing in-truck lighting system (DS) providing short-wavelength enriched light before, during, and after driving. In a within-participants design, eight truck drivers drove a fully-loaded truck under wintry Scandinavian conditions (low daylight levels) with a DS or placebo system for five days. Subjective and objective measures of alertness were recorded several times daily, and evening melatonin levels were recorded three times per study condition. DS significantly increased daytime light exposure without causing negative side effects while driving. In addition, no negative carry-over effects were observed on evening melatonin and sleepiness levels or on nighttime sleep quality. Moreover, objective alertness (i.e., psychomotor vigilance) before and after driving was significantly improved by bright light exposure. This effect was accompanied by improved subjective alertness in the morning. This field study demonstrated that DS was able to increase daytime light exposure in low-daylight conditions and to improve alertness in truck drivers before and after driving (e.g., during driving rest periods). Further studies are warranted to investigate the effects of daylight-supplementing in-cabin lighting on driving performance and road safety measures.
Duet synchronization interventions affect social interactions

Published: April 2024

AbstractHumans’ complex behavior, such as speech, music, or dance, requires us to coordinate our actions with external sounds as well as with social partners. The presence of a partner can influence individuals’ synchronization, and, in turn, social connection with the partner may depend on the degree of synchronization. We manipulated the synchronization quality in intervention conditions to address the causal relationship between observed temporal synchrony and perceived social interaction. Pairs of musician and nonmusician participants first performed a turn-taking task consisting of alternating which partner tapped their melody in synchrony with a metronome (each tap generated the next tone in the melody). In two intervention conditions, participants attempted to synchronize their melodies simultaneously with their partner, either with normal auditory feedback (normal feedback) or randomly placed delayed feedback on 25% of melodic tones (delayed feedback). After each intervention, the turn-taking condition was repeated, and participants completed a questionnaire about connectedness, relationship, and feeling of synchronization with their partner. Results showed that partners’ mean asynchronies were more negative following the delayed feedback intervention. In addition, nonmusician partners’ tapping variability was larger following the delayed feedback intervention when they had the delayed feedback intervention first. Ratings of connectedness, relationship, and feeling of synchronization with their partner were reduced for all participants after the delayed feedback Intervention. We modeled participants’ synchronization performance in the post-intervention turn-taking conditions using delay-coupling oscillator models. Reductions in synchronization performance after delayed feedback intervention were reflected in reduced coupling strength. These findings suggest that turn-taking synchronization performance and social connectedness are altered following short interventions that disrupt synchronization with a partner.

Abstract
The soluble glucose dehydrogenase (sGDH) from Acinetobacter calcoaceticus has been widely studied and is used, in biosensors, to detect the presence of glucose, taking advantage of its high turnover and insensitivity to molecular oxygen. This approach, however, presents two drawbacks: the enzyme has broad substrate specificity (leading to imprecise blood glucose measurements) and shows instability over time (inferior to other oxidizing glucose enzymes). We report the characterization of two sGDH mutants: the single mutant Y343F and the double mutant D143E/Y343F. The mutants present enzyme selectivity and specificity of 1.2 (Y343F) and 5.7 (D143E/Y343F) times higher for glucose compared with that of the wild-type. Crystallographic experiments, designed to characterize these mutants, surprisingly revealed that the prosthetic group PQQ (pyrroloquinoline quinone), essential for the enzymatic activity, is in a cleaved form for both wild-type and mutant structures. We provide evidence suggesting that the sGDH produces H2O2, the level of production depending on the mutation. In addition, spectroscopic experiments allowed us to follow the self-degradation of the prosthetic group and the disappearance of sGDH's glucose oxidation activity. These studies suggest that the enzyme is sensitive to its self-production of H2O2. We show that the premature aging of sGDH can be slowed down by adding catalase to consume the H2O2 produced, allowing the design of a more stable biosensor over time. Our research opens questions about the mechanism of H2O2 production and the physiological role of this activity by sGDH.

Published: April 2024

AbstractElectrical impedance tomography (EIT) is a promising non‐invasive imaging technique that visualizes the electrical conductivity of an anatomic structure to form based on measured boundary voltages. However, the EIT inverse problem for the image reconstruction is nonlinear and highly ill‐posed. Therefore, in this work, a simulated dataset that mimics the human thorax was generated with boundary voltages based on given conductivity distributions. To overcome the challenges of image reconstruction, an ensemble learning method was proposed. The ensemble method combines several convolutional neural network models, which are the simple Convolutional Neural Network (CNN) model, AlexNet, AlexNet with residual block, and the modified AlexNet model. The ensemble models’ weights selection was based on average technique giving the best coefficient of determination (R2 score). The reconstruction quality is quantitatively evaluated by calculating the root mean square error (RMSE), the coefficient of determination (R2 score), and the image correlation coefficient (ICC). The proposed method's best performance is an RMSE of 0.09404, an R2 score of 0.926186, and an ICC of 0.95783 using an ensemble model. The proposed method is promising as it can construct valuable images for clinical EIT applications and measurements compared to previous studies.
