Published: May 2024

AbstractA key issue in the development of theory and models for plasma propulsion devices is to describe the instabilities and fluctuations of the devices. It has been widely recognized that many Hall effect thrusters (HETs) exhibit oscillations at frequencies in the range of ∼ 20 kHz. These ionization-related oscillations are generally referred to as Breathing Mode oscillations and have been the subject of considerable research. Here, for the first time, we report direct temporally resolved measurements of the ground state neutral density variation during the period of the oscillation. We used the laser-based Two-Photon Absorption Laser Induced Fluorescence (TALIF) technique to measure neutrals within the plume of a 1.5 kW HET operating on krypton (Kr). Our TALIF scheme employs a frequency-doubled, pulsed dye laser operating at ∼ 212 nm to probe ground state Kr atoms. A novel phase-binning approach is used to recover the time-dependent signal by assigning the timing of each collected TALIF signal (laser shot) relative to the phase of the discharge current. We find that the neutral density fluctuates quite strongly over the period of the oscillation, and that this fluctuation leads the current fluctuation as expected.

Authors: Gardenier Anne Marte , van Est Rinie , Royakkers Lambèr 
Published: May 2024

AbstractThis article introduces an integrative framework for technological citizenship, examining the impact of digitization and the active roles of citizens in shaping this impact across the private, social, and public sphere. It outlines the dual nature of digitization, offering opportunities for enhanced connectivity and efficiency while posing challenges to privacy, security, and democratic integrity. Technological citizenship is explored through the lenses of liberal, communitarian, and republican theories, highlighting the active roles of citizens in navigating the opportunities and risks presented by digital technologies across all life spheres. By operationalizing technological citizenship, the article aims to address the gap in existing literature on the active roles of citizens in the governance of digitization. The framework emphasizes empowerment and resilience as crucial capacities for citizens to actively engage with and govern digital technologies. It illuminates citizens’ active participation in shaping the digital landscape, advocating for policies that support their engagement in safeguarding private, social, and public values in the digital age. The study calls for further research into technological citizenship, emphasizing its significance in fostering a more inclusive and equitable digital society.
Integrating CoDA and PCA for enhanced characterization of fluvial depositional processes: a case study of the Shendi formation, Sudan

Published: May 2024

AbstractTraditional approaches to fluvial sedimentary analysis often face challenges in deciphering complex, multivariate datasets. This study combines compositional data analysis (CoDA) with principal component analysis (PCA) to enhance the characterization of depositional processes and sub-environments within the Shendi Formation. The PCA applied to centered log ratio (clr)-transformed grain size distributions, reveals three principal components with ~ 91.86% of the data variance explained, representing distinct processes: bedload-dominated channel-bar dynamics, overbank deposition, and high-energy flood events. Specific lithofacies associations strongly correlate to each principal component. This integrated approach enables the identification of subtle yet significant patterns within the complex sedimentological record. The Shendi Formation exhibits characteristics of a dynamic fluvial setting with variations in flow energy, channel migration, and periodic flooding. Our findings demonstrate the power of CoDA-PCA in refining the understanding of fluvial depositional systems and highlight its potential for broader applications.

Abstract

Objective:
This study aimed to assess the actual burden of antibiotic use among end-of-life (EOL) patients in South Korea and to compare trends between cancer and non-cancer decedents.

Design:
Population-based mortality follow-back study.

Setting:
Data from the Korean National Health Insurance Database, covering the period from January1, 2006, to December 31, 2018, provided for research by the National Health Insurance Service (NHIS), were used.

Participants:
All decedents from 2006 to 2018 were included and categorized as cancer decedents or non-cancer decedents.

Methods:
Annual antibiotic consumption rates and prescription rates were calculated, and Poisson regression was used to estimate their trends.

Results:
Overall antibiotic consumption rates decreased slightly among decedents in their final month with a less pronounced annual decrease rate among cancer decedents compared to non-cancer decedents (0.4% vs 2.3% per year, P <.001). Over the study period, although narrow spectrum antibiotics were used less, utilization and prescription of broad-spectrum antibiotics steadily increased, and prescription rates were higher in cancer decedents compared to non-cancer controls. Specifically, carbapenem prescription rates increased from 5.6% to 18.5%, (RR 1.087, 95% CI 1.085–1.088, P <.001) in cancer decedents and from 2.9% to 13.2% (RR 1.115, 95% CI 1.113–1.116, P <.001) in non-cancer decedents.

Conclusions:
Our findings show that patients at the EOL, especially those with cancer, are increasingly and highly exposed to broad-spectrum antibiotics. Measures of antibiotic stewardship are required among this population.
Performing Nigerianness: Equivocal Identities and Digital Legibility of White Women Comedians
Authors: Amaefula Rowland Chukwuemeka 
Published: May 2024

AbstractSabina Yuhas (@Overszabi) and Juliana Belova (@juliewanderz or Oyibo Marlian) are Hungarian and Russian women, respectively, who are fascinated by Nigerian popular culture. Despite their successes in exploiting Black culture to attain wealth and fame in the Nigerian mediasphere, their works have hardly been studied. Close readings and nuanced analyses of their selected TikTok skits show a multiplicity of images that are neither fully European nor Nigerian—equivocal identities—mediating Otherness. However, the longstanding power asymmetries between Africa and Europe characterize their enactments as commodification of Blackness, accounting for why Nigerians who perform “Europeanness” do not attain corresponding success.
Thermal and nutrient stress drove Permian–Triassic shallow marine extinctions

Published: May 2024

Abstract
The Permian–Triassic climate crisis can provide key insights into the potential impact of horizon threats to modern-day biodiversity. This crisis coincides with the same extensive environmental changes that threaten modern marine ecosystems (i.e., thermal stress, deoxygenation and ocean acidification), but the primary drivers of extinction are currently unknown. To understand which factors caused extinctions, we conducted a data analysis to quantify the relationship (anomalies, state-shifts and trends) between geochemical proxies and the fossil record at the most intensively studied locality for this event, the Meishan section, China. We found that δ18Oapatite (paleotemperature proxy) and δ114/110Cd (primary productivity proxy) best explain changes in species diversity and species composition in Meishan’s paleoequatorial setting. These findings suggest that the physiological stresses induced by ocean warming and nutrient availability played a predominant role in driving equatorial marine extinctions during the Permian–Triassic event. This research enhances our understanding of the interplay between environmental changes and extinction dynamics during a past climate crisis, presenting an outlook for extinction threats in the worst-case “Shared Socioeconomic Pathways (SSP5–8.5)” scenario.
High-efficiency tandem Ho:YAG single-crystal fiber laser delivering more than 100 W output power

Published: May 2024

Abstract
We report on a high-efficiency, high-power tandem Ho:YAG single-crystal fiber (SCF) laser in-band pumped by a Tm-doped fiber laser at 1907 nm. In addition to the uniform heat distribution resulting from the large surface-to-volume ratio of this fiber-like thin-crystal rod, the long gain region provided by the tandem layout of two SCFs enables high lasing efficiency and power handling capability. More than 100 W output power is achieved at 2.1 μm, corresponding to a slope efficiency of 70.5% and an optical-to-optical efficiency of 67.6%. To the best of our knowledge, this is the highest output power and efficiency ever reported from SCF lasers in the 2-μm spectral range.
Perturbation analysis for continuous-time Markov chains in a weak sense
Authors: Lin Na , Liu Yuanyuan 
Published: May 2024

AbstractBy the technique of augmented truncations, we obtain the perturbation bounds on the distance of the finite-time state distributions of two continuous-time Markov chains (CTMCs) in a type of weaker norm than the V-norm. We derive the estimates for strongly and exponentially ergodic CTMCs. In particular, we apply these results to get the bounds for CTMCs satisfying Doeblin or stochastically monotone conditions. Some examples are presented to illustrate the limitation of the V-norm in perturbation analysis and to show the quality of the weak norm.
Policing neighborhood boundaries and the racialized social control of spaces
Authors: Neil Roland , Legewie Joscha 
Published: May 2024

AbstractPrior scholarship has established that controlling space is central to policing, while highlighting various ways in which this form of social control can be racialized. Extending this work, we advance a theory on the racialized control of space that predicts a higher level of police stops and lower standards of suspicion along neighborhood racial boundaries, the areas where racial composition changes between adjacent neighborhoods. Our theoretical argument sheds light on the selective enforcement of law and order in these transitional spaces, which is a form of racialized spatial social control. Integrating data from New York City’s Stop, Question, and Frisk program from 2008 to 2012 with extensive neighborhood measures, our analyses reveal that White neighborhoods along boundaries experienced substantially elevated levels of police stops even after conditioning on a wide array of potential confounders. This relationship is partially mediated by elevated crime along neighborhood racial boundaries. Still, a sizable direct effect persists, indicative of the racialized social control of spaces. Further, the police tended to require less suspicion before deciding to conduct stops in White neighborhoods along racial boundaries, but only for Black and Hispanic suspects. Implications for the study of race and policing, law and society, and urban and racial inequality are discussed.
Framing and prosecutorial discretion: evidence from Brazil
Authors: Vilaça Luiz 
Published: May 2024

AbstractPrior studies in the United States argue that the discretionary decisions of federal prosecutors regarding which issues to prioritize are shaped by the politicians who appoint them, while studies on state prosecutors emphasize the role of press coverage and public opinion. However, these studies leave untheorized whether prosecutors’ discretionary decisions are also affected by how their peers frame issues within and beyond prosecution offices. Building on the scholarship of collective action frames, this study develops a framework to explain how prosecutors’ framing work affects their colleagues’ decisions about which issues to focus on. I draw on the case of Brazil, where federal prosecutors focused on crime-fighting and human rights, but in the mid-2010s switched focus to corruption following a large-scale investigation called Lava Jato. I compare Lava Jato with two similarly large investigations that failed to transform corruption into the dominant issue within the Public Prosecutor’s Office. Drawing on 131 original interviews, I show how federal prosecutors’ framing work can persuade their colleagues to focus on the same issue through two stages: (1) conceptualization of versatile frames that speak to problems a variety of issues prosecutors care about and (2) diffusion of frames through professional meetings – providing roadmaps for how other prosecutors can implement the new frame – and to the press, increasing public attention.
Contemporary Financial Nationalism in Theory and Practice
Authors: Johnson Juliet , Barnes Andrew 
Published: May 2024

AbstractThe 2008 global financial crisis and its aftermath provided fertile soil for criticism of and alternatives to the international liberal order, including the rise of financial nationalism. Contemporary financial nationalism is a view of the world that is nationalist in its motivation for political action, financial in its policy focus, and illiberal in its conception of political economy. At the same time, it is fundamentally shaped by its emergence from within the international liberal order, which both constrains the policy options of financial nationalists and provides opportunities for them to draw on transnational financial resources and institutions to advance nationalist causes. This article offers a conceptual analysis of contemporary financial nationalism that explores its fundamental characteristics, explains what is distinctive about it, delineates its four major policy subtypes, identifies the resources and capabilities required to successfully engage in it, and discusses the implications of doing so. It aids researchers in thinking about financial nationalism’s internal workings across different contexts, in understanding why it has lasted as long and spread as far as it has, in considering how it may evolve, and in contemplating how it can affect domestic and international political economies.
Will the Global Plastics Treaty break the plastic wave? The beginning of a long discussion road
Authors: de Sousa Fabiula Danielli Bastos 
Published: May 2024

Abstract
We are experiencing the effects of the triple planetary crisis—climate change, loss of nature, and pollution—aggravated by plastic pollution. Despite widespread global awareness of the adverse effects of plastic pollution, its ongoing increase remains persistent, with an annual increase in plastic consumption and incorrect disposal contributing to this serious problem. In 2022, 175 nations agreed to begin negotiations by the end of 2024 on a binding international agreement to control the life cycle of plastics, including preventing marine pollution. To ensure the efficacy of the Global Plastics Treaty for mitigating plastic pollution, the extensive participation of researchers is imperative. The literature focuses on efforts in line with ongoing negotiations. In this study, a systematic review of the Global Plastics Treaty was conducted. The analyzed literature mainly focuses on the adverse effects of plastic pollution, legislation, governance, and the economy. The resulting comprehensive overview of the subject can support ongoing negotiations and guide future research about the Global Plastics Treaty.
The Mitonuclear Compatibility Species Concept, Intrinsic Essentialism, and Natural Kinds
Authors: Heine Kyle B. , Shech Elay 
Published: May 2024

AbstractThis essay introduces, develops, and appraises the mitonuclear compatibility species concept (MCSC), identifying advantages and limitations with respect to alternative species concepts. While the consensus amongst most philosophers of biology is that (kind) essentialism about species is mistaken, and that species at most have relational essences, we appeal to the MCSC to defend thoroughgoing intrinsic essentialism. Namely, the doctrine that species have fully intrinsic essences and, thus, are natural kinds (of sorts), while allowing that species aren’t categorically distinct.
CRIMINAL INTENT IN NINETEENTH-CENTURY ENGLAND
Authors: Handler Philip 
Published: May 2024

AbstractThis article examines how intention became key to criminal responsibility in nineteenth-century England. It focuses on trials where judges wrested with defence counsel and juries for control over its determination. The most important rule that developed to support proof of intention was the presumption that a person intended the natural and probable consequences of their actions. The article charts the origins and functions of the presumption to offer a revised view of the nineteenth-century foundations of the modern law of criminal intention.
Categorical Inequalities and Canadian Attitudes toward Positive and Negative Rights
Authors: Bloemraad Irene , Harell Allison , Fraser Nicholas A.R. 
Published: May 2024

AbstractLiberal democracies are expected to provide residents with both negative rights, such as limitations against the abuse of police powers, and some range of positive (social) rights, such as access to social benefits. These rights are commonly deemed to apply equally, without respect to individuals’ ascriptive backgrounds. Existing research, often in the US context and focused on social programs, shows both support for abstract rights and group-specific prejudices. We interrogate whether similar patterns exist in Canada and innovate by directly examining negative and positive rights in the same study. Using a series of novel survey experiments, we demonstrate the degree to which categorical inequalities based on race and legal status affect public support for rights provision in Canada. Both rights are more recognized for citizens relative to out-of-status migrants, and legal status at times interacts with racialized minority status. Rights appear far from universal in the minds of Canadians.

Abstract
In the past decade, interest has significantly increased regarding the medicinal and nutritional benefits of pomegranate (Punica granatum) peel. This study examined the effects of using pomegranate peel extract (PGE) alone and in combination with albendazole (ABZ) on ultrastructural and immunological changes in cystic echinococcosis in laboratory-infected mice. Results revealed that the smallest hydatid cyst size and weight (0.48 ± 0.47mm, 0.17 ± 0.18 gm) with the highest drug efficacy (56.2%) was detected in the PGE + ABZ group, which also exhibited marked histopathological improvement. Ultrastructural changes recorded by transmission electron microscopy including fragmentation of the nucleus, glycogen depletion, and multiple lysosomes in vacuolated cytoplasm were more often observed in PGE + ABZ group. IFN-γ levels were significantly increased in the group treated with ABZ, with a notable reduction following PGE treatment, whether administered alone or in combination with ABZ. Thus, PGE enhanced the therapeutic efficiency of ABZ, with improvement in histopathological and ultrastructural changes.
On abstract goals’ perverse effects on proxies: The dynamics of unattainability
Authors: Fernández-Dols José-Miguel 
Published: May 2024

Abstract
Proxies should not be classified as failures or successes because, in most cases, they are impossible translations of abstract, polysemous goals to supposedly univocal concrete measures. The “success” or “failure” of a proxy does not depend on its actual accuracy as a valid indicator of goal attainment, but on a social system's willingness to maintain an illusion of its accomplishment.
It's the biology, stupid! Proxy failures in economic decision making
Authors: Sacco Pier Luigi 
Published: May 2024

Abstract
Utilitarian characterizations of economic decision making fail to capture the complex, conditional, and heterogeneous motivations underlying human behavior as shaped by the predictive, multicriterial drivers of biological regulation. Unless economic models start to acknowledge that humans have bodies and a biology with its own adaptive logic and tradeoffs, economic policies will be systematically exposed to, and systematic generators of, proxy failures.
Language anxiety does not affect the growth of L2 reading achievement: The latent growth curve model approach
Authors: Sparks Richard L. , Alamer Abdullah 
Published: May 2024

AbstractSecond language (L2) anxiety has been proposed to play a causal role in L2 achievement. However, most studies have failed to acknowledge confounding variables that may be relevant to the study of anxiety and L2 achievement or to investigate the causal effect of L2 anxiety using longitudinal data. For these reasons, we investigated the effect of L1 reading achievement, L2 aptitude, and L2 anxiety as covariates on the growth of L2 reading achievement across three time points. We used the latent growth curve model (LGCM) to estimate the growth trajectory of US secondary school students’ L2 reading growth in Spanish (N = 307) over three school years. The findings showed that students’ L1 reading achievement and L2 aptitude strongly and significantly predicted L2 reading achievement growth. However, L2 anxiety did not predict L2 reading achievement growth. Findings suggest that growth in L2 reading achievement depends on the language-related skills used for L1 reading and the language skills that comprise L2 aptitude, but not on anxiety. Similar to past cross-sectional studies, L2 anxiety related only to initial levels of L2 reading achievement, suggesting that anxiety reflects students’ initial experience of L2 reading but not their L2 achievement.
