Electromechanical ice protection system: de-icing capability prediction considering impedance matching effect
Authors: Miao B. , Yuan L. , Zhu C.L. 
Published: March 2024

AbstractDue to the safety threats caused by icing, the de-icing system is essential in the aviation industry. As an effective method, the electromechanical de-icing system (EDS) is a new ice-protection system based on mechanical vibration principles. For the majority of the current research on system de-icing capability estimation, the effect of impedance-matching is not considered. Impedance matching plays a very important role in improving the performance of the electromechanical system, so we must also consider the impact of impedance matching when designing the EDS. In the present study, a de-icing capability prediction method considering the impact of an impedance-matching device is established based on experimental and numerical methods. The results indicate that the impedance-matching effect has no impact on the mechanical vibration of the structure for the same load power. Meanwhile, impedance-matching devices can significantly improve the power factor and increase the interface shear stress/strain for de-icing. Eight different vibrational modes were tested, and the experimental results showed that the actual interface shear strain after impedance matching is inversely proportional to the de-icing time. The verification experiments were conducted and the accuracy of the proposed prediction method was verified.

ABSTRACT:There are numerous challenges pertaining to epilepsy care across Ontario, including Epilepsy Monitoring Unit (EMU) bed pressures, surgical access and community supports. We sampled the current clinical, community and operational state of Ontario epilepsy centres and community epilepsy agencies post COVID-19 pandemic. A 44-item survey was distributed to all 11 district and regional adult and paediatric Ontario epilepsy centres. Qualitative responses were collected from community epilepsy agencies. Results revealed ongoing gaps in epilepsy care across Ontario, with EMU bed pressures and labour shortages being limiting factors. A clinical network advising the Ontario Ministry of Health will improve access to epilepsy care.
When data meets citizens: an investigation of citizen engagement in data-driven innovation programmes
Authors: Thuermer Gefion , Walker Johanna , Simperl Elena , Carr Les 
Published: March 2024

Abstract
Publicly funded data-driven innovation programmes frequently involve partnerships between small and medium enterprises (SMEs) and municipal authorities utilizing citizen data. The intention of these projects is to benefit citizens. However, few such projects achieve success or impact within the project timeframe. This may result in benefit accruing mainly to the SME partner, who gains both learning and data, engendering questions of data justice around whether citizen data are being exploited without sufficient benefit returning to citizens. Through case studies composed of interviews and document analysis, we examine how benefits for citizens are conceived and achieved in the publicly funded data-driven air quality projects Data Pitch and Smart Cities Innovation Framework Implementation. We find the differences between the programme funders’ policies had a clear influence on the citizen engagement elements. There are also a number of ways in which the desired citizen engagement and benefit becomes diluted, including through misalignment of incentives and focus, a lack of prioritization and ownership, and power imbalances between citizens and the other actors in the quadruple helix model. To retain the focus on ensuring citizens benefit from data-driven innovation programmes using citizen data, we propose the use of data Justice plans. More work is required to specify the content and mechanisms of such plans for application in such programmes.
Suppressing filamentation instability due to laser beam self-filtering
Authors: Silin Dmitry , Khazanov Efim 
Published: March 2024

Abstract
The development of small-scale self-focusing in a nonlinear Kerr medium after preliminary self-filtering of a laser beam propagating in free space is studied numerically. It is shown that, under definite conditions, due to self-filtering, filamentation instability (beam splitting into filaments) either occurs at significantly larger values of the B-integral, or does not occur at all. In the latter case, there develops the honeycomb instability revealed in this work. This instability is the formation of a random honeycomb structure in the beam cross-section. It is shown that self-filtering can significantly increase the permissible values of the B-integral, at which the beam quality remains acceptable.
Sexual Violence and Two Types of Moral Wrongs
Authors: Lin Ting-an 
Published: March 2024

AbstractAlthough the idea that sexual violence is a “structural” problem is not new, the lack of specification as to what that entails blocks effective responses to it. This paper illustrates the concept of sexual violence as structural in the sense of containing a type of moral wrong called “structural wrong” and discusses its practical implications. First, I introduce a distinction between two types of moral wrongs—interactional wrongs and structural wrongs—and I argue that the moral problem of sexual violence includes both types, each of which calls for a different set of moral responses. Second, drawing on Iris Marion Young's social connection model of responsibility, I argue that recognizing the structural-wrong element of sexual violence does not reduce individual perpetrators’ responsibility for it. Instead, it implies that a broader group of agents are required to join collective actions to reform the social structure. I conclude by evaluating some preventive programs against sexual violence through the lens of structural wrongs and providing directions to advance them.
Epistemic Diversity and Epistemic Advantage: A Comparison of Two Causal Theories in Feminist Epistemology
Authors: Jeong Tay 
Published: March 2024

AbstractFeminist epistemology aims to propose epistemic reasons for increasing the representation of women or socially subordinated people in science. This is typically done—albeit often only implicitly—by positing a causal mechanism through which the representation of sociodemographic minorities exerts a positive effect on scientific advancement. Two types of causal theories can be identified. The “epistemic diversity thesis” presents a causal path from sociodemographic diversity to scientific progress mediated by epistemic diversity. The “thesis of epistemic advantage” proposes a causal path from social subjugation to capacity for inquiry. The latter theory is defined with substantial ambiguity in the existing literature, and I present an explicit causal reformulation that disambiguates it. The epistemic diversity thesis focuses on the effect of group composition on collective epistemic performance and is largely silent about what kind of characteristics lead to individual epistemic excellence. On the other hand, the thesis of epistemic advantage seeks to identify sociodemographic background conditions that make certain epistemic agents strictly better knowers or inquirers than others and pays little attention to the synergistic effects of diverse group composition. Such a difference in the causal structure reflects the diverging political characteristics of the two theories.
Spatial discretization effects in spanwise forcing for turbulent drag reduction
Authors: Gallorini Emanuele , Quadrio Maurizio 
Published: March 2024

Wall-based spanwise forcing has been experimentally used with success by Auteriet al.(Phys. Fluids, vol. 22, 2010, 115103) to obtain large reductions of turbulent skin-friction drag and considerable energy savings in a pipe flow. The spatial distribution of the azimuthal wall velocity used in the experiment was not continuous, but piecewise constant. The present study is a numerical replica of the experiment, based on a set of direct numerical simulations (DNS); its goal is the identification of the effects of spatially discrete forcing, as opposed to the idealized sinusoidal forcing considered in the majority of numerical studies. Regardless of the discretization, with DNS the maximum drag reduction is found to be larger: the flow easily reaches complete relaminarization, whereas the experiment was capped at 33 % drag reduction. However, the key result stems from the observation that, for the piecewise-constant forcing, the apparent irregularities of the experimental data appear in the simulation data too. They derive from the rich harmonic content of the discontinuous travelling wave, which alters the drag reduction of the sinusoidal forcing. A detailed understanding of the contribution of each harmonic reveals that, whenever for example technological limitations constrain one to work far from the optimal forcing parameters, a discrete forcing may perform very differently from the corresponding ideal sinusoid, and in principle can outperform it. However, care should be exercised in comparison, as discrete and continuous forcing have different energy requirements.
A glaciotectonic landform in the Shyok valley, Trans-Himalayan Karakoram Range, India
Authors: Paul Abdul Qayoom , Bahuguna Harish , Kumar Parveen 
Published: March 2024

Abstract
This study reports and discusses the first case of glaciotectonic landforms in the Shyok valley of the Trans-Himalayan Karakoram Range, Ladakh, where a large decomposed granite megablock (8.2 km2) along with underlying diamicton is thrust over the unconsolidated Quaternary glaciofluvial sediments along a fault gouge zone near the village of Khalsar. The absence of deformation signatures below the fault gouge indicates that the brittle fault acted as a décollement surface under frozen conditions along which the glaciotectonic megablock was translated. The other deformation features include slickensides, ductile shear, thrust propagation fold noses, clastic dykes and rafts of granite and slate within the diamicton sediments. These features indicate a subglacial glaciotectonic nappe origin of the landform. The presence of juxtaposed brittle to ductile deformation fabric, clastic dykes and the superimposition of deformed decomposed granite and diamicton over the undisturbed fluvial sediments indicates a permafrost glacial margin and proglacial environment under sufficient subglacial hydrodynamic conditions for the entrapment and transportation of the glaciotectonic megablock. The deformation fabric consistently shows a southeast orientation, indicating an advancing glacier motion from northwest to southeast. The Siachen Glacier which formerly flowed down the Nubra valley is the most likely cause of the Khalsar glaciotectonic landform.
In Search of Hope: Reimagining the “Dark” in Latin American Marxian Ethnographies
Authors: Teófilo da Silva Cristhian 
Published: March 2024

AbstractMarxian anthropology is a particular trend of “dark anthropology.” Michael Taussig has dedicated his work to understanding the connections of colonialism, capitalism, and local cultures under a Marxian-Benjaminian perspective. This article examines the meanings of hope and future concealed within Taussig’s “dark ethnographies” accomplished in Latin America. The purpose of this analysis is to echo Taussig’s concern to write efficiently against terror to acknowledge that even ethnographies of violence and social injustice can carry powerful cultural messages of hope.
Compensation and Tax Fairness: Evidence From Four Countries
Authors: Alvarado Mariana 
Published: March 2024

AbstractThis paper uses a conjoint survey experiment fielded in the US, Australia, Chile, and Argentina to develop and test the compensatory theory of tax fairness, which states that higher taxes on the rich can be used to compensate for other benefits unequally granted by the state. Drawing on social psychology, this paper argues that evidence of preferential treatment by the state violates well-established fairness principles and shows, experimentally, that it leads to taxation to restore equality in crisis times, irrespective of wealth and across a variety of settings. The paper makes two important contributions: it provides the first direct, causal evidence of the importance of compensatory arguments for tax preferences and presents unconfounded estimates of the effect of more established fairness considerations as benchmarks against which to compare the importance of compensatory arguments.
GROUP MINDS IN ANCIENT GREEK HISTORIOGRAPHY AND THE ANCIENT GREEK NOVEL: HERODIAN'S HISTORY AND CHARITON'S CALLIRHOE
Authors: Chrysanthou Chrysanthos S. 
Published: March 2024

AbstractThis article explores Herodian's History of the Roman Empire alongside Chariton's novel Callirhoe with an eye to how the minds of collective entities are represented and function in the two narratives. It argues that Chariton, unlike Herodian, elaborates on the diversity of emotions that characterizes a specific collective experience and has groups use direct speech throughout. These choices add vividness to the narrative and intensify the fictional sensationalism and dramatic character of the novel. It also shows that, whereas collectives in Chariton's narrative are primarily designed to highlight a specific characteristic of a hero, dramatize an event and enhance suspense, in Herodian's historiography they are an integral part of the plot and central to his historical analysis of contemporary political and social world. This article offers a new analytical tool geared towards the development of a poetics of the collective in ancient narrative as well as a poetics of fictional and factual narration in antiquity, and advances our understanding of the complex relationship between ancient historiography and novelistic writing.
Market Liquidity in a Natural Experiment: Evidence from CDS Standard Coupons
Authors: Wang Xinjie , Wu Ge , Zhong Zhaodong (Ken) 
Published: March 2024

Abstract
The credit default swap (CDS) Big Bang introduced 2 standard coupons for CDS trading. We exploit the setting of the 2 standard coupons as a natural experiment to quantify the components of the bid–ask spreads in over-the-counter markets. We find that a significant portion of the difference in the bid–ask spread between the 2 coupons is explained by the difference in funding costs. Furthermore, search intensity also explains the variation in the difference in bid–ask spread. The liquidity typically concentrates on one of the standard coupons and can suddenly switch to the other coupon. Using the sudden switch of the primary coupon, we provide further evidence to support the predictions of search-based liquidity models.

Published: March 2024

AbstractBackground:Shared genetic risk between schizophrenia (SCZ) and bipolar disorder (BD) is well-established, yet the extent to which they share environmental risk factors remains unclear. We compare the associations between environmental exposures during childhood/prior to disorder onset with the risk of developing SCZ and BD.Methods:We conducted a Swedish register-based nested case–control study using 4184 SCZ cases and 18 681 BD cases diagnosed 1988–2013. Cases were matched to five controls by birth year, birth region, and sex. Conditional logistic regression was used to estimate incidence rate ratios (IRR) for SCZ and BD for each exposure (severe childhood infections, adverse childhood experiences (ACEs), substance use disorders (SUDs), urban birth/longest residence).Results:All SUD types were associated with very high risk (IRR 4.9–25.5), and all forms of ACEs with higher risk (IRR 1.5–4.3) for both disorders. In the mutually adjusted models, ACEs demonstrated slightly higher risk for BD (SCZ IRR 1.30, 1.19-1.42; BD IRR 1.49, 1.44–1.55), while for SUD, risk was higher for SCZ (SCZ IRR 9.43, 8.15–10.92; BD IRR 5.50, 5.15–5.88). Infections were associated with increased risk of BD (IRR 1.21, 1.17–1.26) but not SCZ. Urban birth and urban longest residence were associated with higher risk of SCZ (IRR 1.19, 1.03–1.37), while only the combination of urban birth and rural longest residence showed higher risk for BD (IRR 1.24, 1.13–1.35).Conclusions:There were both shared and unique environmental risk factors: SUDs and ACEs were risk factors for both disorders, while infections were more strongly associated with BD and urbanicity with SCZ.
Who receives most? Gendered consequences of divorce on public pension income in West Germany and Sweden
Authors: Schmauk Sarah , Kridahl Linda 
Published: March 2024

Abstract
Sweden and West Germany have had persistently high divorce rates in recent decades, but these two welfare states were differently equipped to mitigate the economic consequences of divorce for individual security in old age: Sweden followed a gender-equal policy approach to enable women and men to achieve economic autonomy, while West Germany, following the male-breadwinner model, introduced the system of ‘divorce-splitting’ to account for differences in women's and men's income. Against this background, this study uses large-scale register data from the German Public Pension Fund and the Swedish population registers to examine how divorce is related to the monthly public old-age pension income of women and men. The main comparison groups are divorced and (re)married individuals who entered retirement between 2013 and 2018. We descriptively show annual income histories from ages 20 to 65, and calculate monthly public old-age pension income with respect to lifetime income and pension regulations, such as the supplements/deductions for ‘divorce-splitting’. Multiple ordinary least square regression models further examine how family status relates to monthly public old-age pension income by gender. The results reveal that women and men in Sweden experience similar working histories, although women's incomes are lower. This is also reflected in women still having lower pension incomes than men. However, divorced and married women show comparable pension incomes, while divorced men receive approximately 26 per cent less pension income than married men. In West Germany, divorced women have significantly higher pension incomes than married women. The system of ‘divorce-splitting’ increases women's and decreases men's pension incomes, which seems to equalise their pension incomes. However, both stay below a married man's pension income. The findings indicate economic inequality in public old-age pension income by family status in Sweden and West Germany.
Extreme precipitation event at the Ross Ice Shelf during the 1911–1912 South Pole run
Authors: Zinkova Mila 
Published: March 2024

AbstractIn March 1912, Captain Robert Falcon Scott and his companions perished on their return journey from the South Pole. The Final Blizzard delivered a terminal blow. However, it was only a part of this story of endurance and tragedy. In December 1911, en route to the South Pole, the men had been tent-bound for 4 days due to an exceptionally warm, wet blizzard. This article compares the meteorological situation that the polar party encountered in December 1911 to a similar situation in the modern time and suggests a possible climatology behind the 1911 event.
How a defensive mindset develops from early adverse experiences and guides antisocial outcomes
Authors: Dodge Kenneth A. 
Published: March 2024

AbstractDante Cicchetti has had a lasting impact on our understanding of the development of externalizing psychopathology through at least two seminal contributions, including establishment of the field of developmental psychopathology and assertion of the hypothesis that early physical abuse and neglect trigger a cascade of maladaptive outcomes across the life course. These ideas have guided a program of research on children’s deviant social information processing and defensive mindset as the psychological mechanisms through which early physical abuse leads to long-term psychopathology. Longitudinal studies following children from early life through mid-adulthood show that physical abuse in the first five years of life leads children to adopt a defensive mindset that, in turn, cascades into long-term outcomes of externalizing psychopathology, incarceration, and dysfunction. Cicchetti’s ideas have also guided the development of preventive interventions to interrupt this life course.

Published: March 2024

AbstractSweetpotato [Ipomoea batatas (L.) Lam.] is a staple crop that provides nutritional benefits to humans globally, but it is subject to yield loss when competing with weeds, especially during the early stage of establishment. Yield loss can vary widely based on the cultivar, production environment, weed species, and management techniques. To address this challenge, we conducted field research at the Samuel G. Meigs Horticulture Research Farm, Lafayette, IN, and at the Southwest Purdue Agricultural Center, Vincennes, IN, in 2022 to determine the effect of sweetpotato cultivar on the critical weed-free period. The experiment was a split-plot design, with weed-free interval treatments as the main plot factor and cultivar as the subplot factor. The three cultivars used were ‘Covington’, ‘Monaco’, and ‘Murasaki’. Weeds were removed by hand and allowed to establish and compete with the crop beginning at 0, 14, 21, 28, 35, or 42 d after transplanting (DAP). As the weed-free interval increased from 0 to 42 DAP, predicted total yield increased from 19 kg ha−1 to 20,540 kg ha−1 for Covington, 3 kg ha−1 to 11,407 kg ha−1 for Monaco, and 125 kg ha−1 to 13,460 kg ha−1 for Murasaki at the Lafayette location. At Vincennes, as the weed-free interval increased from 0 to 42 DAP, predicted total yield increased from 14,664 kg ha−1 to 33,905 kg ha−1 for Covington, 4,817 kg ha−1 to 18,059 kg ha−1 for Monaco, and 12,735 kg ha−1 to 21,105 kg ha−1 for Murasaki. A threshold of ≤10% total yield reduction was achieved by maintaining sweetpotatoes weed-free 24 DAP for Covington, 20 DAP for Murasaki, and 33 DAP for Monaco.
