Authors: Hidalgo Rogel José Manuel , Martínez Beltrán Enrique Tomás , Quiles Pérez Mario , López Bernal Sergio , Martínez Pérez Gregorio , Huertas Celdrán Alberto
Published: January 2024

Driver drowsiness is a significant concern and one of the leading causes of traffic accidents. Advances in cognitive neuroscience and computer science have enabled the detection of drivers’ drowsiness using Brain-Computer Interfaces (BCIs) and Machine Learning (ML). However, the literature lacks a comprehensive evaluation of drowsiness detection performance using a heterogeneous set of ML algorithms, being also necessary to study the performance of scalable ML models suitable for groups of subjects. To address these limitations, this work presents an intelligent framework employing BCIs and features based on electroencephalography for detecting drowsiness in driving scenarios. The SEED-VIG dataset is used to evaluate the best-performing models for individual subjects and groups. Results show that Random Forest (RF) outperformed other models used in the literature, such as Support Vector Machine (SVM), with a 78% f1-score for individual models. Regarding scalable models, RF reached a 79% f1-score, demonstrating the effectiveness of these approaches. This publication highlights the relevance of exploring a diverse set of ML algorithms and scalable approaches suitable for groups of subjects to improve drowsiness detection systems and ultimately reduce the number of accidents caused by driver fatigue. The lessons learned from this study show that not only SVM but also other models not sufficiently explored in the literature are relevant for drowsiness detection. Additionally, scalable approaches are effective in detecting drowsiness, even when new subjects are evaluated. Thus, the proposed framework presents a novel approach for detecting drowsiness in driving scenarios using BCIs and ML.
Microstructure and thermal properties of dissimilar M300-CuCr1Zr alloys by multi-material laser-based powder bed fusion
Authors: Li Xiaoshuang , Sukhomlinov Dmitry , Que Zaiqing
Published: January 2024

Multi-material laser-based powder bed fusion (PBF-LB) allows manufacturing of parts with 3-dimensional gradient and additional functionality in a single step. This research focuses on the combination of thermally-conductive CuCr1Zr with hard M300 tool steel. Two interface configurations of M300 on CuCr1Zr and CuCr1Zr on M300 were investigated. Ultra-fine grains form at the interface due to the low mutual solubility of Cu and steel. The material mixing zone size is dependent on the configurations and tunable in the range of 0.1–0.3 mm by introducing a separate set of parameters for the interface layers. Microcracks and pores mainly occur in the transition zone. Regardless of these defects, the thermal diffusivity of bimetallic parts with 50vol% of CuCr1Zr significantly increases by 70%–150% compared to pure M300. The thermal diffusivity of CuCr1Zr and the hardness of M300 steel can be enhanced simultaneously by applying the aging heat treatment.
Do users adopt extremist beliefs from exposure to hate subreddits?
Authors: Schmitz Matheus , Muric Goran , Hickey Daniel , Burghardt Keith
Published: January 2024

Social media offers an avenue for like-minded individuals to interact in ways that were previously not possible. Yet, it can also be a breeding ground for hate and extremism to spread. Despite research into hate speech on social media, its influence on users adopting extremist beliefs is less understood. In this study, we use causal analysis to quantify extremist adoption resulting from users becoming active in hate online communities known as subreddits. Using an interrupted time series research design, we compare users who became involved in hate subreddits (treatment group) to those who did not (control group). This analysis is reproduced across ten different subreddits covering four different topics: Alt-Right, Racism, Sexism, and Fat-Shaming. From these analyses, we uncover a causal link between a user becoming active in a hate community and using more hate speech both within hate subreddits and across the wider platform. The results are consistent and replicate across communities. Our findings are tentative evidence that users adopt extremist ideas from exposure to hate subreddits.
When remediating one artifact results in another: control, confounders, and correction
Authors: Colaço David
Published: January 2024

Scientists aim to remediate artifacts in their experimental datasets. However, the remediation of one artifact can result in another. Why might this happen, and what does this consequence tell us about how we should account for artifacts and their control? In this paper, I explore a case in functional neuroimaging where remediation appears to have caused this problem. I argue that remediation amounts to a change to an experimental arrangement. These changes need not be surgical, and the arrangement need not satisfy the criterion of causal modularity. Thus, remediation can affect more than just the factor responsible for the artifact. However, if researchers can determine the consequences of their remediation, they can make adjustments that control for the present artifact as well as for previously controlled ones. Current philosophical accounts of artifacts and the factors responsible for them cannot adequately address this issue, as they do not account for what is needed for artifact remediation (and specifically correction). I support my argument by paralleling it with ongoing concerns regarding the transparency of complex computational systems, as near future remediation across the experimental life sciences will likely make greater use of AI tools to correct for artifacts.

Published: January 2024

Driver steering intention prediction provides an augmented solution to the design of an onboard collaboration mechanism between human driver and intelligent vehicle. In this study, a multi-task sequential learning framework is developed to predict future steering torques and steering postures based on upper limb neuromuscular electromyography signals. The joint representation learning for driving postures and steering intention provides an in-depth understanding and accurate modelling of driving steering behaviours. Regarding different testing scenarios, two driving modes, namely, both-hand and single-right-hand modes, are studied. For each driving mode, three different driving postures are further evaluated. Next, a multi-task time-series transformer network (MTS-Trans) is developed to predict the future steering torques and driving postures based on the multi-variate sequential input and the self-attention mechanism. To evaluate the multi-task learning performance and information-sharing characteristics within the network, four distinct two-branch network architectures are evaluated. Empirical validation is conducted through a driving simulator-based experiment, encompassing 21 participants. The proposed model achieves accurate prediction results on future steering torque prediction as well as driving posture recognition for both two-hand and single-hand driving modes. These findings hold significant promise for the advancement of driver steering assistance systems, fostering mutual comprehension and synergy between human drivers and intelligent vehicles.
On the Use of Monotonicity-Preserving Interpolatory Techniques in Multilevel Schemes for Balance Laws
Authors: Baeza Antonio , Donat Rosa , Martínez-Gavara Anna
Published: January 2024

Cost-effective multilevel techniques for homogeneous hyperbolic conservation laws are very successful in reducing the computational cost associated to high resolution shock capturing numerical schemes. Because they do not involve any special data structure, and do not induce savings in memory requirements, they are easily implemented on existing codes and are recommended for 1D and 2D simulations when intensive testing is required. The multilevel technique can also be applied to balance laws, but in this case, numerical errors may be induced by the technique. We present a series of numerical tests that point out that the use of monotonicity-preserving interpolatory techniques eliminates the numerical errors observed when using the usual 4-point centered Lagrange interpolation, and leads to a more robust multilevel code for balance laws, while maintaining the efficiency rates observed for hyperbolic conservation laws.
Up-to-date studies regarding the determination of sertraline by different analytical methods
Authors: Alessa Hussain , Algethami Nasser
Published: January 2024

Sertraline (SER), aka Zoloft, is one of modern antidepressant, it belongs to the selective serotonin reuptake inhibitor class, which functions to raise serotonin levels in the nervous system. SER has both mood-boosting and depressive effects but has bad influence on the gastrointestinal system. The monitor of SER and its major metabolites, desmethyl-SER (DSER) provides useful information that may assist treatments, particularly during adverse reactions or lack of response to the applied therapy. The determination of SER and its metabolites in different samples, like blood, urine, deceased people and water requires various selective, sensitive and reliable analytical methods. These methods would determine and quantify of the whole drug level, as in blood, or unbound form level, as in urine or saliva. The purpose of the current review is to provide a summary of the outcomes of the methods that have been used for the extraction of SER from different sample's types as well as some of the analytical methods that were used for its quantitative analysis. The work targeted the studies of the last decade.
Wanet: weight and attention network for video summarization
Authors: Basu Arpan , Pramanik Rishav , Sarkar Ram
Published: January 2024

In this paper, we propose a deep learning-based model, called Weight and Attention Network (WANet), for video summarization. The network comprises a simple multi-head attention mechanism, followed by a feed-forward network to obtain the frame importance scores. Summary keyshots are obtained from the scores using a combination of kernel temporal segmentation and the knapsack algorithm. Contrary to past methods, we first enrich the input frames with similar information as opposed to letting the model learn all the features by itself. A novel weight assignment mechanism is introduced to assign weights to the input frames based on their similarity before passing the same to the model. Experimental results on the SumMe and TVSum datasets indicate the effectiveness of the present method when compared to state-of-the-art methods applied to the same datasets.
Exploring the impact of acute physical activity on creative thinking: a comprehensive narrative review with a focus on activity type and intensity
Authors: Chen Chong
Published: January 2024

Recent studies have increasingly focused on the cognitive benefits of acute physical activity, particularly in enhancing creative thinking. Despite extensive research linking physical activity and creative cognition, significant gaps remain in understanding how specific types and intensities of physical activities influence this relationship. This review aims to synthesize the current findings, highlighting the notable impact of various physical activities on creative thinking. One key finding is the enhancement of divergent thinking, a critical component of creativity, through activities like walking at a natural pace. Moderate intensity aerobic exercise and dance, though based on limited studies, also appear to facilitate divergent thinking. Additionally, vigorous intensity aerobic exercise may enhance secondary aspects of divergent thinking, including the quantity and flexibility of idea generation. However, the review also identifies multiple research gaps, especially on the effects of resistance exercise and structured moderate to vigorous intensity aerobic exercise on creative thinking, pointing to an area ripe for future exploration. Recognizing the critical importance of creative thinking, it becomes essential to understand how different physical activities, and their intensity levels, affect creative cognition. This knowledge can guide both academic research and practical applications, offering valuable insights for targeted strategies aimed at enhancing cognitive function and creativity through physical activity in real-world settings such as classrooms and workplaces. The review underscores the need for a more comprehensive exploration of this topic, which could have significant implications for the fields of cognitive and exercise psychology.
The liminal state of academic freedom: navigating corporatization in higher education
Authors: Alibašić Haris , L. Atkinson Christopher , Pelcher Jamee
Published: January 2024

For decades, academic freedom and shared governance have stood as cornerstones of higher education in the United States, but these principles face unprecedented challenges. Recent developments point to a disturbing decline in these critical values, stirring debates on the future viability of the higher education system. This study delves into the problematic trajectory of modern higher education, spotlighting the rise of corporate practices within academic institutions, the swelling ranks of university administration, and the disproportionate weight given to student evaluations in assessing faculty. These factors have converged to push academia into an unstable transition, a liminal phase fueled by external and internal forces. This study examines the evolving landscape of academic freedom within the corporatized university model. Utilizing the concept of liminality, it explores the transitional challenges faced by academia in balancing traditional scholarly values with emerging market-driven paradigms, arguing that the corporatization of universities represents a liminal phase, wherein the identity and purpose of academic institutions are in flux, significantly impacting the notion of academic freedom. The shift toward a consumer-oriented ethos endangers the foundational principles of higher education, risking substituting educational substance with the mere transaction of educational services. The study concludes by issuing a call to action for all stakeholders in higher education to acknowledge and confront these detrimental trends, thereby safeguarding the principles of academic freedom, shared governance, and the educational system's overall integrity and dynamism.
Low-cycle fatigue testing and microstructure of high strength-ductility structural steel materials
Authors: Bai Yongtao , Gong Qingyu , Zhou Xuhong , Babacan Nazim , Guan Shaoyu
Published: January 2024

The well-known tradeoff between strength and ductility is a key issue in the large-scale engineering application of steel materials to resist fatigue due to earthquakes and other vibrational excitations. The steel production industry provides a vast range of technologies to achieve the desired performances. Through experimental research, it was found that FeCrNi-based high-ductility steel (HD-S) can demonstrate remarkable hysteresis behavior due to extensive deformation capacity of strain-hardening until the ultimate fracture, compared to industrially manufactured high-strength steel (HS-S) with the level of 1 GPa in yield strength. The balance between strength and ductility can be realized by slightly adding the percentage of Ni by 5% to achieve a ductile hysteresis behavior. Moreover, the HD-S specimens exhibit greater resistance to low-cycle fatigue with large plastic amplitude. By developing a new damage evolution law based on instantaneous damage differential during nonstationary fatigue history, the fatigue life of materials is extended into the inelastic hinges of flexural beams/origami components. The proposed approach enables the fatigue design of steel structural components with desirable disaster-prevention capacities for complex steel structures.
State Estimation for Robotics
Authors: Barfoot Timothy D.
Published: January 2024

A key aspect of robotics today is estimating the state (e.g., position and orientation) of a robot, based on noisy sensor data. This book targets students and practitioners of robotics by presenting classical state estimation methods (e.g., the Kalman filter) but also important modern topics such as batch estimation, Bayes filter, sigmapoint and particle filters, robust estimation for outlier rejection, and continuous-time trajectory estimation and its connection to Gaussian-process regression. Since most robots operate in a three-dimensional world, common sensor models (e.g., camera, laser rangefinder) are provided followed by practical advice on how to carry out state estimation for rotational state variables. The book covers robotic applications such as point-cloud alignment, pose-graph relaxation, bundle adjustment, and simultaneous localization and mapping. Highlights of this expanded second edition include a new chapter on variational inference, a new section on inertial navigation, more introductory material on probability, and a primer on matrix calculus.
Elite Women and the Italian Wars, 1494–1559
Authors: Broomhall Susan , James Carolyn
Published: January 2024

The Element analyses the critical importance of elite women to the conflict conventionally known as the Italian Wars that engulfed much of Europe and the Mediterranean between 1494 and 1559. Through its considered attention to the interventions of women connected to imperial, royal and princely dynasties, the authors show the breadth and depth of the opportunities, roles, impact, and influence that certain women had to shape the course of the conflict in both wartime activities and in peace-making. The work thus expands the ways in which the authors can think about women's participation in war and politics. It makes use of a wide range of sources such as literature, art and material culture, as well as more conventional text forms. Women's voices and actions are prioritized in making sense of evidence and claims about their activities.
Identity, Capabilities, and Changing Economics
Authors: Davis John B.
Published: January 2024

Mainstream economics assumes economic agents act and make decisions to maximize their utility. This model of economic behavior, based on rational choice theory, has come under increasing attack in economics because it does not accurately reflect the way people behave and reason. The shift towards a more realistic account of economic agents has been mostly associated with the rise of behavioral economics, which views individuals through the lens of bounded rationality. Identity, Capabilities, and Changing Economics goes further and uses identity analysis to build on this critique of the utility conception of individuals, arguing it should be replaced by a conception of economic agents in an uncertain world as socially embedded and identified with their capabilities. Written by one of the world's leading philosophers of economics, the book develops a new approach to economics' theory of the individual, explaining individuals as adaptive and reflexive rather than utility maximizing.

A NOTE CONCERNING THE RELATIONSHIP BETWEEN “BUTCHER DING” AND “NOURISHING LIFE” IN THE TRADITIONAL ZHUANGZI COMMENTARIES
Authors: Williams John
Published: January 2024

The present discussion aims to help corroborate recent claims that the link between nourishing life 養生 and the Butcher Ding 庖丁 vignette from chapter 3 of the Zhuangzi 莊子 (c. fourth to third century bce) might be taken seriously, while at the same time falsifying recent claims that it is nonetheless uncommon for the connection to be taken seriously. This is achieved by supplying several pieces of textual evidence from leading figures from throughout the history of Zhuangzi studies who all explicitly make the connection and take it seriously. Beyond corroborating one claim and falsifying the other, the present discussion provides renderings of much hitherto untranslated work so as to prevent future scholars from underestimating just how common it is to take the link between the Butcher Ding story and nourishing life seriously.
The Creation of a Gendered Division of Labor in Mule Spinning: Evidence from Samuel Oldknow, 1788–1792
Authors: Tertzakian Alexander
Published: January 2024

The spinning mule was one of the most important innovations in the rise of the British cotton industry during the Industrial Revolution. First introduced in 1780, the mule’s diffusion overturned the traditional division of labor in spinning from women to men. This article produces new insights on this process by examining the business records of Samuel Oldknow, a pioneer of fine cotton manufacturing and an early adopter of the technology during the understudied transition period of the late 1780s and early 1790s, when the machine was still hand powered before the factory system. It demonstrates that strength was the most important factor in shaping the gendered division of labor in mule spinning. Although no direct gender-pay discrimination is evident, men’s earnings were higher because of the physical effort required to operate the larger mules that more easily produced the finest yarns that secured the highest piece rates. Crucially, this shift of the gender division of labor predated factory mule spinning.
Diagnostic stewardship to improve patient outcomes and healthcare-associated infection (HAI) metrics

Diagnostic stewardship seeks to improve ordering, collection, performance, and reporting of tests. Test results play an important role in reportable HAIs. The inclusion of HAIs in public reporting and pay for performance programs has highlighted the value of diagnostic stewardship as part of infection prevention initiatives. Inappropriate testing should be discouraged, and approaches that seek to alter testing solely to impact a reportable metric should be avoided. HAI definitions should be further adapted to new testing technologies, with focus on actionable and clinically relevant test results that will improve patient care.
Evolution of weak, homogeneous turbulence with rotation and stratification
Authors: Scott J.F. , Cambon C.
Published: January 2024

This article concerns the time-evolution, spectral structure and scaling of weak turbulence subject to rotation and stable stratification. The flow is expressed as a combination of particular solutions, referred to as modes, of the linearised governing equations without viscosity or diffusion. Modes are of two types: oscillatory ones which represent inertial-gravity waves and time-independent ones that express a non-propagating (NP) component of the flow. The presence of the NP component, which plays an active role in the dynamics apart from in the case of pure rotation, renders wave-turbulence analysis problematic because the NP mode is non-dispersive. Equations are derived for the time evolution of the modal amplitudes, evolution which is due to nonlinearity and visco-diffusion. Subsequent analysis assumes that one or other (or both) of the Rossby and Froude numbers is small (weak turbulence). Given this assumption, the NP component is found to evolve independently of the wave one and a numerical scheme, similar to, though significantly different from classical direct numerical simulation, is used to determine its time evolution. The treatment of the wave component assumes its amplitude is large compared with the NP one, otherwise there are seemingly intractable difficulties of closure in the analysis. Given this further assumption, the wave component decouples from the NP one. Evolution equations for the wave spectra are derived using wave-turbulence analysis and are integrated numerically. As might be expected, these equations indicate that nonlinear coupling of wave modes is dominated by resonances. Results are given for both the NP and wave components.
Turbulent mixing in the vertical magnetic Rayleigh–Taylor instability
Authors: Briard A. , Gréa B.-J. , Nguyen F.
Published: January 2024

The presence of a mean magnetic field aligned with the direction of the acceleration greatly modifies the development of the Rayleigh–Taylor instability (RTI). High resolution direct numerical simulations of the Boussinesq–Navier–Stokes equations under the magnetohydrodynamics approximation reveal that, after an initial damping of the perturbations at the interface between the two miscible fluids, a rapid increase of the mixing layer is observed. Structures are significantly stretched in the vertical direction because magnetic tension prevents small-scale shear instabilities. When the vertical turbulent velocity exceeds the Alfvén velocity, the flow transitions to turbulence, structures break and an enhanced mixing occurs with strong dissipation. Afterwards, the mixing zone slows down and its growth rate is decreased compared to the hydrodynamic case. For larger magnitudes of the mean magnetic field, a strong anisotropy persists, and an increased fraction of potential energy injected into the system is lost into turbulent magnetic energy: as a consequence, the mixing zone growth rate is decreased even more. This phenomenology is embedded in a general buoyancy-drag equation, derived from simplified equations that reflect the large-scale dynamics, in which the drag coefficient is increased by the presence of turbulent magnetic energy.
A comparison between the FENE-P and sPTT constitutive models in large-amplitude oscillatory shear
Authors: John T.P. , Poole R.J. , Kowalski A.J. , Fonte C.P.
Published: January 2024

The finitely extensible nonlinear elastic with Peterlin closure (FENE-P) and simplified Phan-Thien–Tanner (sPTT) viscoelastic models are used widely for modelling of complex fluids. Although they are derived from distinct micro-structural theories, these models can become mathematically identical in steady and homogeneous flows with a particular choice of the values of the model parameters. However, even with this choice of parameter values, the model responses are known to differ from each other in transient flows. In this work, we investigate the responses of the FENE-P and sPTT constitutive models in large-amplitude oscillatory shear (LAOS). In steady shear, the shear stress scales with the non-dimensional group

$Wi/(aL)$

(

$Wi\,\sqrt {\epsilon }$

) for the FENE-P (sPTT) model, where

$Wi$

is the Weissenberg number,

$L^2$

is the limit of extensibility in the FENE-P model (

$a$

being

$L^2/(L^2-3)$

), and

$\epsilon$

is the extensibility parameter in the sPTT model. Our numerical and analytical results show that in LAOS, the FENE-P model shows this universality only for large values of

$L^2$

, whereas the sPTT model shows it for all values of

$\epsilon$

. In the strongly nonlinear region, there is a drastic difference between the responses of the two models, with the FENE-P model exhibiting strong shear stress overshoots that manifest as self-intersecting secondary loops in the viscous Lissajous curves. We quantify the nonlinearity exhibited by each constitutive model using the sequence of physical processes framework. Despite the high degree of nonlinearity exhibited by the FENE-P model, we also show using fully nonlinear one-dimensional simulations that it does not shear band in LAOS within the range of conditions studied.
Controlled mean dynamics of red blood cells by two orthogonal ultrasonic standing waves
Authors: Liu Yifan , Xin Fengxian
Published: January 2024

A computational model is developed to study the time-averaged mean dynamics of red blood cells (RBCs) driven by the time-averaged mean stress generated by two phase-shifted orthogonal ultrasonic standing waves in a viscous fluid. The cell is modelled as an ellipsoidal viscoelastic membrane enclosing the viscous fluid cytoplasm, the motion of which is described by the inclination angle of the ellipsoidal cell shape and the phase angle of the potential membrane cycle. Based on the acoustic perturbation method, the acoustic field and acoustic streaming field are solved to obtain the time-averaged mean stress, and then the temporal evolution equations of the inclination and phase angles of the cell are determined considering the torque balance and energy conservation. At a small acoustic pressure amplitude, this model reproduces the experimentally observed features of cell motion in orthogonal standing waves: the transition from steady stationary orientation to unsteady tumbling with the increase of the phase difference between the two standing waves. By turning up the acoustic pressure amplitude above a critical value, it is further predicted that the previously observed motions can be accompanied by the membrane tank-treading rotation. Observations of these motions, combined with the present computational model, can help to evaluate the mechanical properties of RBC membranes in an automated and high-throughput manner by acoustic methods.

Branching patterns of wave trains in mass-in-mass lattices
Authors: Zhang Ling , Guo Shangjiang
Published: January 2024

We investigate the existence and branching patterns of wave trains in the mass-in-mass (MiM) lattice, which is a variant of the Fermi–Pasta–Ulam (FPU) lattice. In contrast to FPU lattice, we have to solve coupled advance-delay differential equations, which are reduced to a finite-dimensional bifurcation equation with an inherited Hamiltonian structure by applying a Lyapunov–Schmidt reduction and invariant theory. We establish a link between the MiM lattice and the monatomic FPU lattice. That is, the monochromatic and bichromatic wave trains persist near

$\mu =0$

in the nonresonance case and in the resonance case

$p:q$

where

$q$

is not an integer multiple of

$p$

. Furthermore, we obtain the multiplicity of bichromatic wave trains in

$p:q$

resonance where

$q$

is an integer multiple of

$p$

, based on the singular theorem.
House Members on the News: Local Television News Coverage of Incumbents
Authors: Huber Gregory A. , Tucker Patrick D.
Published: January 2024

The accountability relationship between voters and elected members of Congress (MCs) hinges on the potential for citizens to learn about legislator behaviour. In an era of declining local newspapers, local television coverage of MCs potentially fulfils this important role. However, few studies have comprehensively examined the determinants of contemporary MC coverage by local television news broadcasts. In this paper, we leverage a vast database of local television news broadcast transcripts spanning two years to identify which factors explain MC coverage. We find that MCs receive little coverage outside the general election campaign season. Media market and campaign-specific factors are associated with more exposure when coverage occurs. Finally, we find that within competitive elections, incumbents receive only a marginal advantage in coverage. These findings provide a springboard to explore further questions regarding Congress, local media, and political accountability.

We establish a new improvement of the classical Lp-Hardy inequality on the multidimensional Euclidean space in the supercritical case. Recently, in [14], there has been a new kind of development of the one-dimensional Hardy inequality. Using some radialisation techniques of functions and then exploiting symmetric decreasing rearrangement arguments on the real line, the new multidimensional version of the Hardy inequality is given. Some consequences are also discussed.

What's in a Name? To Call or Not To Call the Revolutionary Guards a Terrorist Organization
Authors: Bolourchi Neda
Published: January 2024

To make sense of the Woman, Life, Freedom uprising (Zan, Zendegi, Azadi; WLF), some have asked straightforward questions: Why now? What are the reasons for it? Who is behind the uprising? The Islamic Republic of Iran, its supporters, and its allies have responded to the last question by labeling protestors as spies or provocateurs influenced and supported by foreign governments or activists. By raising the possibility of outside interference to bring about regime change through the participation of willing or even unsuspecting Iranians, the Islamic Republic defends its extreme responses to the WLF uprising and dismisses the international community's condemnations of human rights abuses.
Politics of Vengeance in Iranian Diaspora Communities
Authors: Rahimieh Nasrin
Published: January 2024

The death of the young Kurdish Iranian woman, Mahsa Jina Amini, on September 16, 2022 following her arrest by Iran's now-suspended Gasht-i Irshad (guidance patrol or morality police) for apparent lax conformity to the Islamic dress code ignited protests across Iran. The protests, known as Women, Life, Freedom (Zan, Zendegī, Azadi) quickly spread to Iranian diaspora communities across North America, Europe, and Australia. Initially, diasporic Iranians organized their protests to support and amplify their compatriots’ calls for justice. As the protests continued in Iran and the demands for change grew louder, some members of the Iranian diaspora shifted their focus from the Islamic Republic to the public shaming of Iranians living outside Iran for their purported support of the Iranian regime. Some of the tactics employed by those engaged in public humiliations of suspected regime supporters recalled Gasht-i Irshad's methods of trapping and accosting individuals for perceived infractions. These public confrontations were aimed at isolating, shaming, and silencing perceived allies of the Islamic Republic and, by extension, denouncing the regime for its abrogation of women's and human rights. I refer to this phenomenon among diasporic Iranians as gasht-i intiqām, roving avengers, which reflects a frustration with the absence of justice in Iran and targets purported proxies for the regime. There have been many instances and types of denunciations aimed at silencing and ostracizing individuals, academics, and institutions. As Daniel Block points out in his analysis, “The attacks overwhelmingly target women, most notably in North America and Europe. The victims include gender equality activists, journalists, foreign policy analysts and a historian, each of whom has been accused of colluding with the authoritarian Islamist regime in Tehran.” Block further points out that many of the attacks are anonymous or originate from fake social media accounts. The common denominator he finds among those who target individuals is opposition to “Western-Iranian diplomacy or reporting information that adds subtlety to the debate over how the United States and its allies should handle the Islamic Republic.”1 Often those deemed regime collaborators are Iranian American individuals, journalists, or institutions that supported the 2015 the Joint Comprehensive Plan of Action, otherwise known as the nuclear deal.
(Mis)translating the Life Stories of the “Heroes of the Year 2022: Women of Iran”
Authors: Zarabadi Ladan
Published: January 2024

“Woman, Life, Freedom” (Zan, Zendegi, Azadi) is the main motto of the 2022 Iranian uprising that started in September. This revolutionary movement began after Mahsa Amini's murder while in custody of the Islamic Republic's “morality police” due to not wearing hijab “properly.” Iranian women have resisted the sexist policies of the Islamic Republic since its inception. They are protesting in the streets again, endangering their lives to call for structural political change. They have been deservedly recognized as heroes of 2022 in a Time Magazine article by Azadeh Moaveni, journalist, writer, and associate professor of journalism at New York University.1 Moaveni's approach departs from the Western imperialist and Orientalist image of Iranian and Muslim women as docile individuals, clad in black chadors, and isolated from public spaces. Yet her analysis results in a new misrepresentation of Iranian women: a counterimage that looks anti-imperialist yet projects another one-dimensional reductionist representation that also risks serving the Islamic Republic and fulfilling its need for international legitimacy.2

These fragments once belonged to the same ‘N-Psalter’ as fragments earlier found in Cambridge (Dietz 1968), Haarlem (Derolez 1972), Sondershausen (Pilch 1997; Gneuss 1998) and Elbląg (Opalińskaet al.2023). The article provides analyses of the language and textual affiliations of the Old English gloss and aims to reconstruct the provenance of the fragments and the N-Psalter as a whole. The annotated edition includes appendices with collations of the Latin and Old English texts of other extant glossed psalters.
On the dynamic residual measure of inaccuracy based on extropy in order statistics

Published: January 2024

In this paper, we introduce a novel way to quantify the remaining inaccuracy of order statistics by utilizing the concept of extropy. We explore various properties and characteristics of this new measure. Additionally, we expand the notion of inaccuracy for ordered random variables to a dynamic version and demonstrate that this dynamic information measure provides a unique determination of the distribution function. Moreover, we investigate specific lifetime distributions by analyzing the residual inaccuracy of the first-order statistics. Nonparametric kernel estimation of the proposed measure is suggested. Simulation results show that the kernel estimator with bandwidth selection using the cross-validation method has the best performance. Finally, an application of the proposed measure on the model selection is provided.
More Graduates, Fewer Skills? Vocational Education Expansion and Skilled Labour Shortages in China
Authors: Song Xinmiao , Xu Duoduo
Published: January 2024

China's need for skilled workers to upgrade its industrial system is increasingly urgent due to global economic competition. Despite massive expansion of its Vocational Education and Training system over the past two decades, a significant skilled labour deficit remains. Current debates on the inefficacy of vocational education focuses on the lack of institutional synergies between education and industry but often overlooks the inherent conflicts within the vocational education system and micro-level skill formation processes. Our ethnographic research in two upper-secondary vocational schools unveils a disturbing trend: the rapid massification of vocational education, which prioritizes student enrolment numbers over educational quality, fails to address the demand for skill formation and skilled labour. It inadvertently generates adverse consequences for both administrative management and classroom instruction. Skill development frequently falls to after-school professional associations and an exclusive group of elite students. Meanwhile, reform initiatives, such as the craftsmanship campaign and skill competitions, benefit only a few without improving the employment prospects for the wider student population. These findings call for greater attention to the inherent tensions within China's Vocational Education and Training system. Only when there is a deeper understanding of the underlying causes of ineffective skill formation in vocational schools can China achieve its national goal of industrial upgrades.

Legionellosis is a disease caused by the bacterium Legionella that most commonly presents as Legionnaires’ disease (LD), a severe form of pneumonia. From 2015 to 2019, an average of 438 LD cases per year were reported in Canada. However, it is believed that the actual number of cases is much higher, since LD may be underdiagnosed and underreported. The purpose of this study was to develop an estimate of the true incidence of illnesses, hospitalizations, and deaths associated with LD in Canada. Values were derived using a stochastic model, based on Canadian surveillance data from 2015 to 2019, which were scaled up to account for underdiagnosis and underreporting. Overall, there were an estimated 1,113 (90% CrI: 737–1,730) illnesses, 1,008 (90% CrI: 271–2,244) hospitalizations, and 34 (90% CrI: 4–86) deaths due to domestically acquired waterborne LD annually in Canada from 2015 to 2019. It was further estimated that only 36% of illnesses and 39% of hospitalizations and deaths were captured in surveillance, and that 22% of illnesses were caused by Legionella serogroups and species other than Legionella pneumophila serogroup 1 (non-Lp1). This study highlights the true burden and areas for improvement in Canada’s surveillance and detection of LD.
Wobbling nature of gamma passing rate as a function of calibration field sizes in patient-specific quality assurance

Published: January 2024

Purpose:

This study aimed to investigate the influence of calibration field size on the gamma passing rate (GPR) in patient-specific quality assurance (PSQA).

Methods:

Two independent detectors, PTW OCTAVIUS 4D (4DOCT) and Arc Check, were utilised in volumetric modulated arc therapy plans for 26 patients (14 with Arc Check and 12 with 4DOCT). Plans were administered using Varian Unique machine (with 4DOCT) and Varian TrueBeam (with Arc Check), each employing different calibration factors (CFs): 4 × 4, 6 × 6, 8 × 8, 10 × 10, 12 × 12 and 15 × 15 cm2 field sizes. Gamma analysis was conducted with 2%2mm, 2%3mm and 3%3mm gamma criteria.

Results:

GPR exhibited variations across different CFs. GPR demonstrated an increasing trend below 10 × 10 cm² CFs, while it displayed a decreasing trend above 10 × 10 cm². Both detectors exhibited similar GPR patterns. The correlation between 4DOCT and Arc Check was strong in tighter criteria (2%2mm) with an R² value of 0·9957, moderate criteria (2%3mm) with an R² value of 0·9868, but reduced in liberal criteria (3%3mm) with an R² value of 0·4226.

Conclusion:

This study demonstrates that calibration field sizes significantly influence GPR in PSQA. This study recommends the plan specific calibration field must obtain to calibrate the QA devices for modulated plans.
Pronominal Adverbs in German: A Grammaticalization Account
Authors: Pittner Karin
Published: January 2024

Pronominal adverbs in German, which consist of da ‘there’, hier ‘here’, or wo ‘where’ as first element and a preposition as second element, like davor ‘before’, hierbei ‘hereby’, worin ‘wherein’, have often been explained by a movement of the first element out of the complement position of the preposition. This article points out some of the problems of movement analyses and presents an alternative account based on the diachronic development of pronominal adverbs. It is argued that the pattern after which pronominal adverbs are formed can be traced back to the univerbation of two adverbs with spatial meaning. This is accompanied by processes often associated with grammaticalization, such as semantic bleaching, phonological reduction, and a loss of separability in the standard variety. Some of the reduced forms are obligatory in phrasemes and particle verbs, thus constituting a split which can occur during grammaticalization. The reduction of the first element of pronominal adverbs and a doubling of the first element can be seen as part of a grammaticalization cycle.
Processing Factors Constrain Word-Order Variation in German: The Trouble with Third Constructions
Authors: Felser Claudia , Bosch Sina
Published: January 2024

A subset of German control verbs allows for the discontinuous linearization of their infinitival complements, a word-order pattern known as the “third construction” pattern. Compared to alternative word-order options (notably, extraposition), third constructions are very rare in present-day German. Here we ask whether the third construction pattern’s low occurrence frequency can be accounted for by processing factors. We report the results from a self-paced reading task and a production priming task investigating whether third constructions are difficult to comprehend, difficult to produce, or both. Our results show that the third construction pattern’s local structural ambiguity impedes comprehension, and that the pattern is also resistant to priming. We conclude that this word-order pattern is an example of a “latent” construction that is grammatically licensed but strongly dispreferred in language use because easier-to-process word-order variants are available.
