The Normative Role of the Circular Plastics Alliance in the EU’s Transition towards a European Circular Economy for Plastics
Authors: O’Halloran Amy
Published: May 2024

The global pollution and waste crisis presents us with environmental and economic challenges which if not properly addressed could destabilise or threaten the survival and welfare of societies. The European Union is responding to the waste and pollution crisis through its circular economy agenda that adopts a broad life-cycle approach to the regulation of plastics from production, consumption, disposal, and recycling. To operationalise its agenda, the European Union seeks to inter alia mobilise all actors towards the objective of improving the economics of plastic recycling. Given the potential for conflicts and disputes to proliferate across a broad range of societal actors and interests, it is perhaps not surprising that when we examine the evolving EU legal and normative framework for a circular plastics economy, we observe a polycentric governance arrangement that includes the EU institutions, the Circular Plastics Alliance (CPA), and European standardisation organisations (i.e. CEN and CENELEC). The normative interactions amongst these governance bodies will not easily be unveiled and understood if we enclose our perspectives and analyses within the limits of traditional legal paradigms that only focus upon the formal law-making processes that flow through the European Parliament, Council, and Commission. However, by applying Karl Llewellyn’s law-jobs theory in this article, it is possible to analyse how a multiplicity of governance bodies perform certain legal functions that are contributing to the development of regulatory order for a European circular plastics economy. This article sets out a number of key findings in relation to the evolving legal and normative framework for a European circular plastics economy pertaining to the role of the CPA in framing problems, theorising solutions, and shaping the pathway of normative development towards a European circular plastics economy. To date, the CPA has identified obstacles to the expansion of the European recycled plastics market, and mapped the areas in need of standardisation if such obstacles are to be overcome This work by the CPA has prompted the European Commission to submit a standardisation request to the CEN and CENELEC calling for the development of harmonised standards to facilitate greater plastic recycling. While compliance with CEN and CENELEC standards would be voluntary, such standards could interact with the EU’s proposed Ecodesign Regulation and any delegated acts adopted thereto, thereby creating legal obligations for a wide range of actors across plastic value chains.

Published: May 2024

There have been massive advances in AI technologies towards addressing the contemporary challenge of fake news identification. However, these technologies, as observed widely, have not had the same kind or depth in impact across global societies. In particular, the AI scholarship in fake news detection arguably has not been as beneficial or appropriate for Global South, bringing geo-political bias into the picture. While it is often natural to think of data bias as the potential reason for geo-political bias, other factors could be much more important in being more latent, and thus less visible. In this commentary, we investigate as to how the facet of affect, comprising emotions and sentiments, could be a potent vehicle for geo-political biases in AI. We highlight, through assembling and interpreting insights from literature, the overarching neglect of affect across methods for fake news detection AI, and how this could be a potentially important factor for geo-political bias within them. This exposition, we believe, also serves as a first effort in understanding how geo-political biases work within AI pipelines beyond the data collection stage.
Anticipating impacts: using large-scale scenario-writing to explore diverse implications of generative AI in the news environment
Authors: Kieslich Kimon , Diakopoulos Nicholas , Helberger Natali
Published: May 2024

The tremendous rise of generative AI has reached every part of society—including the news environment. There are many concerns about the individual and societal impact of the increasing use of generative AI, including issues such as disinformation and misinformation, discrimination, and the promotion of social tensions. However, research on anticipating the impact of generative AI is still in its infancy and mostly limited to the views of technology developers and/or researchers. In this paper, we aim to broaden the perspective and capture the expectations of three stakeholder groups (news consumers; technology developers; content creators) about the potential negative impacts of generative AI, as well as mitigation strategies to address these. Methodologically, we apply scenario-writing and use participatory foresight in the context of a survey (n = 119) to delve into cognitively diverse imaginations of the future. We qualitatively analyze the scenarios using thematic analysis to systematically map potential impacts of generative AI on the news environment, potential mitigation strategies, and the role of stakeholders in causing and mitigating these impacts. In addition, we measure respondents' opinions on a specific mitigation strategy, namely transparency obligations as suggested in Article 52 of the draft EU AI Act. We compare the results across different stakeholder groups and elaborate on different expected impacts across these groups. We conclude by discussing the usefulness of scenario-writing and participatory foresight as a toolbox for generative AI impact assessment.
Automated floodwater depth estimation using large multimodal model for rapid flood mapping
Authors: Akinboyewa Temitope , Ning Huan , Lessani M. Naser , Li Zhenlong
Published: May 2024

Information on the depth of floodwater is crucial for rapid mapping of areas affected by floods. However, previous approaches for estimating floodwater depth, including field surveys, remote sensing, and machine learning techniques, can be time-consuming and resource-intensive. This paper presents an automated and rapid approach for estimating floodwater depth from on-site flood photos. A pre-trained large multimodal model, Generative pre-trained transformers (GPT-4) Vision, was used specifically for estimating floodwater. The input data were flood photos that contained referenced objects, such as street signs, cars, people, and buildings. Using the heights of the common objects as references, the model returned the floodwater depth as the output. Results show that the proposed approach can rapidly provide a consistent and reliable estimation of floodwater depth from flood photos. Such rapid estimation is transformative in flood inundation mapping and assessing the severity of the flood in near-real time, which is essential for effective flood response strategies.

Published: May 2024

Purpose

To construct an effective prognostic nomogram for patients with clinically localized Acral lentiginous melanoma (ALM).

Methods

This retrospective study included ALM patients from the Surveillance, Epidemiology, and End Results (SEER) database from 2004–2015. The 1686 cases were divided into the training and internal validation cohorts at a ratio of 7:3. The Cox regression analyses were performed to select risk factors for the nomogram. The performances of the nomogram were evaluated using the concordance index (C-index), area under receiver operating characteristic curve (AUC), and calibration plots, and validated in an external multicenter cohort.

Results

Age, gender, race, and stage were significantly associated with overall survival (OS), with a C-index of 0.727 and 0.722 in the training and internal validation groups, respectively. The AUC of 2-,4-, and 6 years were higher than or equal to 0.75. Age, gender, race, site, and stage were related to ALM patients' CSS which have better C-index of 0.791 and 0.774 in the training and internal validation set. The AUC of 2-,4-, and 6- were higher than or equal to 0.80. Both survival calibration curves of 2-,4, and 6-year OS and CSS brought out a good consistency. The external multicenter cohort authenticated the value of the nomogram of OS, with a C-index of 0.657 and an AUC of 0.67, 0.72, and 0.65 at 2, 4, and 6 years. Good consistency was also observed.

Conclusion

A prognostic nomogram was established and validated to help predict the survival of ALM patients and guide individualized treatment strategies.
Construction of a Green and Low-Carbon Travel Order Prediction Model Based on Shared Bicycle Big Data
Authors: Cheng Chuanxu , Yue Wande
Published: May 2024

In the era of big data, traditional analysis methods are insufficient to meet the growing demand for green and low-carbon travel orders in shared bicycle systems. To address this issue, a new order demand forecasting model, named the “convolutional neural network (CNN)”—“long short-term memory (LSTM)” model (CNN-LSTM), is proposed by integrating CNN and LSTM techniques. The research further validates the spatiotemporal prediction performance of this model. The experimental results demonstrate that LSTM exhibits favorable prediction performance in terms of time feature analysis, as evidenced by the overlapping of the true value (TV) and predicted value (PV) curves. Notably, LSTM achieves an impressively low mean squared error (MSE) value of 0.0063, which is significantly lower compared to CNN (0.0082) and XGBoost (0.0074). Upon incorporating date and weather characteristics, the predictive performance improves significantly, achieving an outstanding MSE value of 0.0043. However, when it comes to spatial feature analysis, the LSTM algorithm alone proves inadequate, obtaining a MSE value of 0.0084. Thus, by employing the CNN-LSTM combination model, a lower MSE value of 0.0066 is achieved, outperforming the comparison algorithms. Overall, the CNN-LSTM model exhibits strong predictive capabilities regarding the temporal and spatial requirements of shared bicycles. This model plays a key role in accurately forecasting order demands, facilitating urban transportation planning and management, as well as guiding the planning and location of non-motorized vehicle stops.

Published: May 2024

Background

It remains unknown how the patterns of change of social isolation and loneliness are associated with the onset of cardiovascular disease (CVD) and mortality. We aimed to investigate the longitudinal association of changes in social isolation and loneliness with incident CVD, all-cause mortality, CVD mortality and subsequent cardiac function.

Methods

This prospective cohort study included 18,258 participants aged 38–73 years who participated in visit 0 (2006–2010) and visit 1 (2012–2013) using UK Biobank (mean age 57.1, standard deviation [SD] 7.4; 48.7% males). Social isolation or loneliness was categorized into four patterns: never, transient, incident, and persistent. Incident CVD, all-cause and CVD mortality were ascertained through linkage data. Cardiac function was assessed by cardiovascular magnetic resonance imaging in a subsample (N = 5188; visit 2, since 2014).

Results

Over a median follow-up of 8.3 (interquartile range [IQR] 8.1–8.6) years, compared with never social isolation, persistent social isolation was associated with the higher risk of incident CVD (hazard ratio [HR] 1.17, 95% confidence interval [CI] 1.03–1.33), all-cause (1.42, 1.12–1.81) and CVD (1.53, 1.05–2.23) mortality. Likewise, persistent loneliness was strongly associated with the greater risk of incident CVD (1.13, 1.00–1.27), all-cause (1.28, 1.02–1.61) and CVD mortality (1.52, 1.06–2.18).

Conclusions

Persistent social isolation and loneliness posed a substantially higher risk for incident CVD, all-cause and CVD mortality, and cardiac dysfunction than other patterns. Persistent social isolation and loneliness, along with an increasing cumulative score, are associated with lower cardiac function.

Graphical Abstract
Economic Indicators, Quantity and Quality of Health Care Resources Affecting Post-surgical Mortality
Authors: Merola Raffaele , Vargas Maria
Published: May 2024

Objective

to identify correlations between quality and quantity of health care resources, national economic indicators, and postoperative in-hospital mortality as reported in the EUSOS study.

Methods

Different variables were identified from a series of publicly available database. Postoperative in-hospital mortality was identified as reported by EUSOS study. Spearman non-parametric and Coefficients of non-linear regression were calculated.

Results

Quality of health care resources was strongly and negatively correlated to postoperative in-hospital mortality. Quantity of health care resources were negatively and moderately correlated to postoperative in-hospital mortality. National economic indicators were moderately and negatively correlated to postoperative in-hospital mortality. General mortality, as reported by WHO, was positively but very moderately correlated with postoperative in-hospital mortality.

Conclusions

Postoperative in-hospital mortality is strongly determined by quality of health care instead of quantity of health resources and health expenditures. We suggest that improving the quality of health care system might reduce postoperative in-hospital mortality.
Future sediment transport to the Dutch Wadden Sea under severe sea level rise and tidal range change
Authors: Wang Z. B. , Lodder Q. J. , Townend I. H. , Zhu Yonghui
Published: May 2024

Future sediment transport from the North Sea coasts to the Dutch Wadden Sea for various future sea level scenarios has been studied because it influences the future sand nourishment demand for the maintenance of the coastline and because it determines bio-geomorphological development of the Wadden Sea. The present study focuses on two questions which have not yet been considered in the previous modelling studies using ASMITA: How will the transport develop around drowning of the intertidal flats in the Wadden Sea? How will tidal range change influence the future sediment exchange? By using SLR scenarios with faster acceleration and running the simulations for longer periods of time some inlets exhibited drowning, i.e., where the tidal flat volume vanishes. When drowning occurs, the sediment import rate approaches a maximum or a minimum, depending on the initial morphological state of the tidal inlet system. This maximum or minimum rate for a certain tidal inlet system depends on the SLR scenario. Theoretical analysis as well as modelling results show that tidal range change will influence the sediment import to the Wadden Sea. A tidal range increase will cause a decrease of the sediment demand in the Wadden Sea resulting into less sediment import to the Wadden Sea. It is thus important to study the tidal range development in the Wadden Sea by considering the interaction between SLR, tidal range change and morphological development in the system. It is further concluded that the empirical relation used in the previous studies is not representative of conditions in a tidal basin with fixed basin area, even though this relation has been derived from field observations in many tidal inlet systems worldwide. The equilibrium channel volume should be proportional to the tidal prism instead of to its 1.5th power.
Performance study on vacuum suction blasting by force and velocity measurements of the abrasive flow

Published: May 2024

The automated removal of layers by scarfing to repair carbon fibre reinforced plastics (CFRP) has been investigated with vacuum suction blasting (VSB) showing promising results. However, its removal mechanism and particle behaviour were not yet fully understood. The removal leads to cavities on the surface and the central area is less removed after longer static blasting times. Further theoretical considerations and experiments of measured forces and velocities of the VSB particles can explain these effects to optimize the large-scale removal. Former studies on abrasive blasting used simplified approaches with incompressible Bernoulli equations taking the same velocities of particles and carrier medium. For VSB, the air is much faster than the particles and more complex equations are derived in this study. Additionally, it is taken into account, that the impinging forces act against the vacuum forces.

To specify the power and removal mechanism of VSB for large scale removal, forces and velocities of the blasting particles are studied. Calculations by compressible Bernoulli equations, measurements of blasting particle velocities and impact forces give a good approximation. The air velocities and forces are calculated and compared with the measurements. Forces are measured by a piezo-electric sensor. Particle velocities are measured with a Particle Image Velocimetry (PIV) system tracking the abrasive particle movement through a transparent outer nozzle. The influence of different blasting parameters on the forces and velocities are identified. Results correspond to the material removal from former experiments and indicate the favourable process parameter set. Despite the impinging forces are in general low, they lead together with the particle velocity to the large-scale removal rate. The measured particle directions explain the removal behaviour of this VSB process. The measured velocities match to those well-known from grinding with bonded grinding tools.

Published: May 2024

Air pollution is a pressing problem and causes millions of deaths each year related to its effects on respiratory health worldwide. Despite its significant impact, information on air pollution in many cities, including Hawassa city, remains limited. The aim of this study was to determine the concentrations and variations of traffic-related air pollution, as measured by carbon monoxide, and its relationship with temperature, relative humidity, traffic flow, and road routing in Hawassa City. We monitored carbon monoxide (CO) concentrations in Hawassa city, Ethiopia, for 24 days using real-time monitors with carbon monoxide sensor head. A total of 24 different roads (12 high-traffic congested roads and 12 low-traffic congested roads) were included as monitoring sites. We conducted 1 hour monitoring at each monitoring site in the morning and afternoon to characterize the temporal variations. Accordingly, the average carbon monoxide concentrations varied temporally at different times. In addition, the average carbon monoxide concentrations on paved main roads, traffic light roads and low-traffic flow roads were 4.87 ± 0.6 ppm, 5.38 ± 0.8 ppm and 1.62 ± 0.53 ppm, respectively. The study also identified factors that correlated positively with carbon monoxide concentration, including temperature, relative humidity, traffic flow and road routing. The study concludes that long-term monitoring of carbon monoxide concentrations is necessary to fully characterize the health effects. The study also provides valuable insights for urban planners when implementing measures to mitigate the negative effects.

Published: May 2024

In order to examine the gaseous pollutants generated by artisanal refined gasoline and the contribution to air pollution associated with such combustion in the Niger-Delta region of Nigeria, this study collected a sample of indigenously refined gasoline product each from thirty (30) different randomly selected artisanal camps in the Niger-Delta region and subjected all the collected samples to combustion. Fifty (50) ml of each gasoline sample was combusted at controlled conditions, and the concentrations of gaseous emissions from the process were measured using a combustion emission analyser. Pollutants characterised by the Department of Petroleum Resources which include sulphur dioxide (SO2), carbon monoxide (CO), oxides of nitrogen (NOx), hydrocarbons (HC) and carbon dioxide (CO2) were characterised. The average concentrations of the emissions were 211.50 mg/m3, 7.18 mg/m3, 17.51 mg/m3, 3011.33 mg/m3, and 500.39 mg/m3 for CO, NOx, SO2, CO2, and HC respectively. The concentrations of SO2 and NOx measured were within the Federal Environmental Protection Agency (FEPA) set limits for combustion emissions from stationary sources but breached World Health Organization (WHO), World Bank and Environmental Guidelines and Standard for Petroleum Industry in Nigeria (EGASPIN) set limits. The concentrations of CO and HC exceeded FEPA, WHO, World Bank and EGASPIN set limits and hazardous on Air Quality Index (AQI) classification. Elevated concentrations of CO and HC in the atmosphere pose a major threat to ambient air quality and human health, especially in locations where artisanal-refined fuel is predominantly utilised. Associated risks include poor visibility, occurrence of acid rain, blood poisoning and cancer-related diseases. In addition to these effects are the worsening global warming crises associated with CO2 emission, a major product of fossil fuel combustion.
Family Matters
Authors: George Marie-Amélie
Published: May 2024

In 1960, consensual sodomy was a crime in every state in America. Fifty-five years later, the Supreme Court ruled that same-sex couples had the fundamental right to marry. In the span of two generations, American law underwent a dramatic transformation. Though the fight for marriage equality has received a considerable amount of attention from scholars and the media, it was only a small part of the more than half-century struggle for queer family rights. Family Matters uncovers these decades of advocacy, which reshaped the place of same-sex sexuality in American law and society – and ultimately made marriage equality possible. This book, however, is more than a history of queer rights. Marie-Amélie George reveals that national legal change resulted from shifts at the state and local levels, where the central figures were everyday people without legal training. Consequently, she offers a new way of understanding how minority groups were able to secure meaningful legal change.
Resolving nonuniform flow in gas turbines: challenges, progress, and moving forward
Authors: Lou F.
Published: May 2024

The flow in gas turbines exhibits a highly unsteady, complex and nonuniform manner, which presents two main challenges. Firstly, it introduces instrumentation errors, contributing to uncertainties when calculating one-dimensional performance metrics during rig or engine tests using fixed-location rakes. Secondly, it raises mechanical concerns, including high-cycle fatigue due to blade row interactions in turbomachines and thermal fatigue caused by hot-streaks at the combustor exit. Experimental characterisation of the flow nonuniformity in gas turbines is highly challenging due to the confined space and harsh environment for instrumentation. This paper presents recent efforts to address this issue by resolving the nonuniform flow in gas turbines using spatially under-sampled measurements. The proposed approach utilises discrete probe data and leverages a ‘Fourier-based approximation’ method developed by the author. The technique has undergone preliminary experimental validation involving reconstruction of the total pressure distribution in a multi-stage axial compressor and the total temperature field at the exit of the combustor and high-pressure turbine. Results show that, in the multi-stage axial compressor environment, reconstruction of inter-stage total pressure is achieved using a reduced dataset covering less than 20% of the annulus with reasonably good accuracy. The reconstructed total pressure yields almost identical mean total pressure values at all spanwise locations, with a maximum deviation of less than 0.02%. Additionally, reconstruction of the total temperature distribution at an engine-representative full annulus combustor is achieved using measurements at ten carefully selected circumferential locations. Results show that the reconstructed temperature field successfully captures the primary features associated with combustor exit temperature flow. The reconstructed temperature field yields excellent agreement in the magnitude of radial temperature distribution factor (RTDF) and overall temperature distribution factor (OTDF) predictions to the experiment, with a deviation of less than 0.5% for RTDF and less than 2.5% for OTDF. Lastly, reconstruction of the total temperature distribution at the exit of the GE E3 high-pressure turbine (HPT) is achieved using measurements at eight carefully selected circumferential locations. Results demonstrate remarkable robustness in resolving the temperature profile at the HPT exit with high fidelity, irrespective of the HPT inlet conditions. The initial validation results are promising, demonstrating that the new probe layout scheme and the Fourier-based approximation method enable effective characterisation of flow nonuniformity in gas turbines, thereby providing valuable insights into the complex flow of gas turbine engines.

The optimal use of AMR data must consider challenges within this setting, including high staff turnover, limited diagnostic capacity, and antibiotic shortages.
Affective paternalism
Authors: Dolan Paul , Krekel Christian , Swanke Sarah
Published: May 2024

Many decisions are curated, incentivised or nudged by a third party. Despite this, only a handful of studies have looked at paternalistic decision-makers and the psychological processes by which they arrive at their decisions. The role of affect, in particular, has been ignored so far, and yet restricting agency on a potentially large group of people might be highly unpleasant. We are the first to propose a conceptual framework of affective paternalism which explicitly accounts for the role of affect in paternalistic decision-making, identifying all entry points through which affect may create systematic deviations in decision outcomes. We shed light on some of these phenomena by using a novel survey experiment in which we let participants make paternalistic decisions whilst also asking them about their motivations behind their choices, including cognitive reasons and affect. Our findings suggest that affect may play a significant role in paternalistic decision-making and lead to systematically different decision outcomes. To the extent that these that could result in inefficient, undesirable or unfair consequences, our framework may help more accurately predict a paternalist's decision and suggest entry points for where and possibly how to intervene in the paternalistic decision-making process.
The Distinctive Vocabularies of Right-Wing Populists
Authors: McDonnell Duncan , Ondelli Stefano
Published: May 2024

Right-wing populists are said to employ distinctive language to differentiate themselves from mainstream politicians. However, we know little about what makes their language distinct. We investigate this by assembling a novel corpus of speeches and using an automated text analysis tool to identify the keywords used by three right-wing populist leaders (Donald Trump, Marine Le Pen and Matteo Salvini) and three of their mainstream opponents (Hillary Clinton, Emmanuel Macron and Matteo Renzi). We then examine the contexts in which those keywords are used. We find that, while Trump and Salvini are stylistically populist in different ways to Le Pen, what distinguishes all of them is the clarity of the populist message (people vs elites and others) compared to their vaguer opponents. Our results have implications for how we understand populism as both ideology and style across linguistic contexts, in addition to how we conceive of its specificity compared to the mainstream.
Civic Opposition and Democratic Backsliding: Mobilization Dynamics and Rapport with Political Parties
Authors: Yabanci Bilge
Published: May 2024

Democratic backsliding has posed significant challenges to democracies in many countries. Recent calls for a better theorization of pushback against backsliding have triggered renewed scholarly interest in the field of opposition and its role in stopping or reversing creeping authoritarian rule. This study calls for a theoretical and empirical recalibration of the concept of opposition to account for multifaceted ‘non-partisan’ actors and venues of oppositional mobilization. It proposes a new classification of resilient civic opposition. The explanatory typology is based on two factors: (1) the ability of civic opposition to bring multiple grievances together and to balance between on-street and off-street mediums, and (2) the rapport between political opposition parties and civic opposition. Four cases of civic opposition from Hungary and Turkey illustrate the proposed typology empirically.
Injection-based approaches for controlling Douglas-fir (Pseudotsuga menziesii) invasion in conservation efforts of the Patagonian forest

Published: May 2024

Invasion by nonnative woody species poses a major threat to the environment, biodiversity, and economies worldwide. Nahuel Huapi National Park in Argentina is a protected area for habitat conservation that harbors several invasive Pinaceae species, where Douglas-fir [Pseudotsuga menziesii (Mirb.) Franco] is one of the most aggressive and abundant conifer tree invaders. Management of invasions in protected areas must include efficient, easy to deploy, and cost-effective techniques, while reducing the impact on native ecosystems. Because the region has no control measures applied other than conventional felling, we analyzed the effectiveness of two systemic herbicides (glyphosate and aminopyralid + triclopyr) at two different concentrations, applied with the drill and fill method. We then quantified defoliation of P. menziesii trees 6, 12, and 24 mo after application and performed an economic cost analysis to determine profitability. For the application, the trees were grouped into diameter at breast height classes and randomly assigned to one of the four treatments. Herbicide doses were adjusted according to tree size. We found that glyphosate at high concentrations completely defoliated 33% of the trees after 6 mo and 87% after 12 and 24 mo. Glyphosate at low concentrations defoliated almost 30% of the trees after 24 mo, most of which were smaller trees. The aminopyralid + triclopyr treatment did not produce significant defoliation at any of the tested concentrations. When compared with conventional felling, the drill and fill method was found to reduce removal costs by 98%. We observe that differences in costs are mainly due to dead trees that remain standing, decompose slowly, and do not generate costs associated with their removal and debris management. Drill and fill is a suitable method for treating scattered trees in a native forest community, with reduced environmental consequences compared with other removal techniques currently applied within conservation areas of the Patagonian forest.
Virtual taphonomy of trilobite heads: understanding compressive deformation using 3D modeling and rigid body simulation
Authors: Jung Jikhan , Park Tae-Yoon S. , Hughes Nigel C.
Published: May 2024

Shape deformation during fossilization can prevent accurate reconstruction of an organism's form during life, hampering areas of paleontology ranging from functional morphology to systematics. Retrodeformation attempts to restore the original shape of deformed fossil specimens and requires an adequate knowledge of the deformation process. Although tectonic processes and retrodeformation are relatively well understood, research on quantifying the effect of compressive deformation on fossil morphology is scant. Here we investigate the factors that can cause changes in the shape of fossil specimens during compressive deformation. Three-dimensional (3D) models of trilobite cranidia/cephala are subjected to simulated deposition and compaction using rigid body simulation and scaling features of the open-source 3D software Blender. The variation in pitch and roll angle is lowest on flat surfaces, intermediate on tilted surfaces, and highest on irregular surfaces. These trends are reflected in the morphological differences captured by principal component scores in geometric morphometric analyses using landmarks. In addition, the different shapes of trilobite cranidia/cephala according to their systematic affinity influence the degree of angular variation, which in turn affects their posture—normal or inverted. Inverted cranidia/cephala show greater morphological variability than those with normal postures.
Improving neural machine translation by integrating transliteration for low-resource English–Assamese language
Authors: Nath Basab , Sarkar Sunita , Mukhopadhyay Somnath , Roy Arindam
Published: May 2024

In machine translation (MT), one of the challenging tasks is to translate the proper nouns and technical terms from the source language to the target language while preserving the phonetic equivalent of original term. Machine transliteration, an essential part of MT systems, plays a vital role in handling proper nouns and technical terms. In this paper, a hybrid attention-based encoder–decoder machine transliteration system is proposed for the low-resource English to the Assamese language. In this work, the proposed machine transliteration system is integrated with the previously published hybrid attention-based encoder–decoder neural MT model to improve the translation quality of English to the Assamese language. The proposed integrated MT system demonstrated good results across various performance metrics such as BLEU, sacreBLEU, METEOR, chrF, RIBES, and TER for English to Assamese translation. Additionally, human evaluation was also conducted to assess translation quality. The proposed integrated MT system was compared with two existing systems: the Bing translation service model and the Samanantar Indic translation model.
The Paris System in Western Europe: Minorities, Self-Determination, and the Management of Difference in the “Civilized West”
Authors: Dalle Mulle Emmanuel , Prott Volker , Ambrosino Alessandro
Published: May 2024

In most accounts of peacemaking after World War I, “flawed” decisions at “Versailles” caused the ethnically mixed states of Central and Eastern Europe to descend into violent ethnic clashes, while the allegedly more homogenous Western European states faced few issues with minorities. This article challenges this simplistic view by examining the treatment of German-speaking minorities in the borderlands of Alsace-Lorraine, South Tyrol, and Eupen-Malmedy between 1918 and 1923 in the immediate post-war and the early interwar period. Building on an innovative comparative framework of five key variables, we find that, in all three cases, post-war borders generated incentives for the respective governments to suppress their new minorities, and that states used ethnic markers to target them. The strength of state institutions and liberal principles account for a reversal (Alsace-Lorraine), moderation (Eupen-Malmedy), or hardening (South Tyrol) of measures. International commitment to defend the new borders and the absence of a tradition of ethnic conflict also had a significant impact.
Forming a Ukrainian Diaspora in Poland: Between “Common Culture,” National Naturalism, and Othering
Authors: Trzeszczyńska Patrycja , Demel Grzegorz
Published: May 2024

Poland remained a popular destination for migrants from Ukraine for many years before February 24, 2022, the outbreak of full-scale Russian aggression on Ukraine. Ukrainian communities in Polish cities, including local autochthonous Ukrainians (the Ukrainian national minority), are already well-established and well-organized, although they are very diverse. Drawing from anthropological fieldwork conducted in 2021 and at the beginning of 2022, this article seeks to address the nexus of the diaspora and culture and explores the imaginations of “common culture” in diaspora-forming processes. We treat “culture” as diasporic imaginings of naturalized and reified representations of what is to be a Ukrainian in Poland. The essentialized notion of putative “common culture” is routinely discursivized and maintained by diasporic elites. Exploring this as an empirical phenomenon captured in the field helps reveal the internal tensions and that this imagining empowers the production of cultural differences. We argue that imagined “common culture” may actually activate “othering” of the diasporic Other and might not be as unifying a factor in diaspora-forming processes as it appears.

In the second decade of the fifteenth century, the book-hunter Poggio Bracciolini and two friends recognized Vitruvius’ De architectura among the moldy manuscripts at the monastic library at St. Gall in Switzerland. Although their find was not the first copy of De architectura to be identified, the reception of Vitruvius among Italian humanists tends to be afforded special attention in academic, public, and popular culture alike. Commonly shuffling at the center of that attention is L'Uomo Vitruviano of Leonardo da Vinci, usually dated to the 1490s. In Italian, and in his famous mirror writing, Leonardo mentions Vitruvius by name in the first word of his notes above his rendering of the homo bene figuratus and engages with the content of De architectura 3.1.2f. above and below it.
Debating the Bascom controversy: revisiting the expropriation and repatriation of the Ifẹ̀ bronzes
Authors: Evans Tomos Llywelyn
Published: May 2024

In 1937–38, the American doctoral candidate William R. Bascom conducted anthropological research in the sacred Yorùbá city of Ilé-Ifẹ̀, Nigeria. Bascom’s visit was a decisive moment in the history of African art, as, in 1938, he observed the chance discovery of unique copper and copper alloy heads, two of which he acquired and exported to the USA. Bascom’s actions in 1938, and his subsequent conflicts with British officials who demanded the return of the heads in the 1940s, have become matters of controversy and scholarly debate. Historian Robert Tignor and anthropologist Simon Ottenberg have presented contrasting arguments regarding the affair. This article draws on material from several archives to shed further light on this discussion, resolve remaining areas of dispute, and explore what the study of this controversy tells us about the nature and practice of anthropology, the impacts of Western exhibitions of African art, and early cultural preservation and repatriation efforts of the late colonial period. At a time when colonial-era collecting practices are facing increased critical re-examination, and with intensified calls for the repatriation of Nigerian cultural patrimony in Western museums, this article reflects on how the study of this controversy contributes to present restitution efforts.
Murder in a quarry: violent encounters and distant intimacy on a Cape convict station
Authors: Holdridge Chris
Published: May 2024

This article uses a micro-historical approach to examine an escape and murder among convict labourers between Cape Town and Stellenbosch in Southern Africa in the 1840s. It does so to demonstrate how imperial mobilities and legal conceptions of property crime were interconnected within settler colonial capital and the intimacies of colonial social worlds. Reforms in penal practice in the British Empire – in this instance, adopted in the Cape Colony from Tasmanian experiments in convict labour and moral improvement – formed part of post-abolition shifts in labour control and the management of the itinerant poor, increasingly guided by anxieties over race. Michael O’Brien, the murderer, was a suspected escaped convict from Australia, who claimed to have survived violent encounters in the Pacific as a missionary. His narrative contrasts with the predominantly regional mobilities and crimes of the other Cape convicts – notably stock theft and petty robbery – that occurred in the contested spaces of law, colonialism and property. This article discusses convict narratives around crime and redemption across a maritime empire, and the affective relations of coercion and care between convicts, overseers, constables and superintendents on the smaller scale of a convict station. It further contends that changes in criminal justice and governance in Southern Africa were thus contingent on the intimacies of scale and affect, on connections between the local, the global and the biographical.
Intimacy, labour and sexual violence: Nama and Baster women in Namaqualand’s copper mining district, c.1879–1900
Authors: Herzog Kai F.
Published: May 2024

This article explores the intersection of labour, sexual violence and intimacy in the late nineteenth-century copper mining district of Namaqualand, focusing on the impact of male labourers’ brutalities on local Nama and Baster women. Small in scale, lacking state interference and offering vast employment opportunities to women, Namaqualand’s mines and the towns that grew around them were a key destination for local female labour migration. Due to these unique characteristics, however, women were also exposed to unwanted attention and sexual abuse by male labourers, particularly miners. Women used the Cape’s legal system to protest, but the indifference shown towards their suffering by colonial officials and the public allowed men to use violence without much restraint, rendering women’s legal efforts futile. Ultimately, sexual violence reinforced gendered and racial hierarchies, restricting women’s socio-economic agency and autonomy. The article argues that these dynamics highlight the violent (re)shaping of colonial and patriarchal power asymmetries in the north-western Cape between two major colonial wars after the stabilization of the northern frontier by means of armed conquest.
Imperial debris, intimate partnerships and family law reform in Cameroon
Authors: Kombo Brenda K.
Published: May 2024

This article explores the enduring impact of efforts by the French mandate administration and Spiritan missionaries to regulate intimate partnerships in French Cameroon between 1916 and 1956. Drawing primarily on French archival material, I show how administrators and missionaries sought to domesticate ‘modernity’ through activities targeting women’s status and roles within intimate partnerships. Spiritans promoted monogamous Christian marriage by advocating for Christian legal status and through ‘schools for fiancées’ called sixas, which often provoked violent confrontations. Despite decrying these activities as culturally disruptive, the administration passed significant marriage legislation. While these efforts are characterized as exercises of epistemic violence because of their attempted erasure of women’s and broader local perspectives, I nevertheless highlight their ambiguity. Moreover, garnering insights from history, anthropology, critical legal studies, postcolonial and feminist theory, I argue that remnants of these attempts to reshape intimacy endure as ‘imperial debris’, contributing to the impasse in reforming the Cameroonian Family Code. Further research unearthing local historical perspectives and experiences of intimate partnerships can facilitate more egalitarian family law in Cameroon.
Legacies of Wartime Sexual Violence: Survivors, Psychological Harms, and Mobilization
Authors: LINDSEY SUMMER , KOOS CARLO
Published: May 2024

What are the psychological, social, and political legacies of sexual violence in armed conflicts? While conventional wisdom expects the exclusion of survivors from their societies due to stigma, we advance a theory of sociopolitical mobilization among wartime sexual violence survivors and their households. Our theory emphasizes the value that people place on their communities in conflict-affected contexts and incorporates the psychosocial harms that survivor-households experience as well as their agency. We use an original survey from eastern Democratic Republic of Congo to evaluate the theory. Analyses using list experiment measures of wartime sexual violence show that survivor-households engage in increased levels of social and political activities in their communities. Auxiliary analyses suggest that mobilization is driven by stigmatization and self-blame, a finding that resonates with social psychological research on exclusion and social reconnection.
Separate but Unequal: Ethnocentrism and Racialization Explain the “Democratic” Peace in Public Opinion
Authors: RATHBUN BRIAN C. , PARKER CHRISTOPHER SEBASTIAN , POMEROY CALEB
Published: May 2024

Why are democratic publics reluctant to use force against fellow democracies? We hypothesize that the democratic peace in public opinion owes, in large part, to racialized assumptions about democracy. Rather than regime type per se doing the causal work, the term “democracy” inadvertently primes the presumption that target countries are predominantly white. This implicit racialization, in turn, explains the reluctance of the American public to support aggression against fellow democracies, most notably among respondents higher in ethnocentrism who disproportionately drive the democratic peace treatment effect. Two original survey experiments, a large-scale word embedding analysis of English texts, and reanalyses of published studies support this expectation. Our results suggest that the democratic peace in public opinion is, largely, an ethnocentric and racialized peace. The findings hold implications for the role of racism and racialization in foreign policy opinion research generally.
