Published: May 2024

AbstractAir 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.

AbstractIn 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.
Resolving nonuniform flow in gas turbines: challenges, progress, and moving forward
Authors: Lou F. 
Published: May 2024

AbstractThe 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.
Responding to the AMR threat: data and information needs of stakeholders working in regional and remote Australia

Published: May 2024

Abstract
Our qualitative analysis of interviews with remote Australian healthcare professionals found that they require reliable, local antimicrobial resistance (AMR) data reflecting the geographical diversity of the population they serve. 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

Abstract
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

Abstract
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

Abstract
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

AbstractInvasion 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

Published: May 2024

AbstractShape 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

Published: May 2024

AbstractIn 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

Abstract
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

AbstractPoland 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.
Debating the Bascom controversy: revisiting the expropriation and repatriation of the Ifẹ̀ bronzes
Authors: Evans Tomos Llywelyn 
Published: May 2024

AbstractIn 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

AbstractThis 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

AbstractThis 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.
