Authors: Brody Judith , Ben Ishai Meydan , Serov-Volach Irena , Mano-Tamir Keren , Gaton Dan D. , Avisar Inbal
Published: March 2024

Purpose

To describe the prevalence and outcome of motor vehicle accidents-associated ocular injuries.

Methods

A survey of patients who presented to the emergency room at a level 1 trauma center with motor vehicle accidents-associated ocular injuries. A patient questionnaire and review of clinical notes were conducted for all patients.

Results

Of 274 motor vehicle accident victims with ocular injuries who presented to the emergency room, 40 (15%) responded to the survey. Over half of them were driving a vehicle, and most reported wearing a seat belt or a helmet. Most ocular injuries were mild. The most common injuries were bone fractures, subconjunctival hemorrhage, eyelid involvement and corneal injury. Most respondents had no change in vision and perceived their ocular involvement as a minor part of their injury. Most respondents returned to work and to driving within a year.

Conclusion

Our study sheds light on the details and extent of ocular involvement and the visual ability to perform daily activities following motor vehicle accidents.

Published: March 2024

Context

The recent WHO 2022 Classification of pituitary tumours identified a novel group of ‘plurihormonal tumours without distinct lineage differentiation (WDLD)’. By definition, these express multiple combinations of lineage commitment transcription factors, in a monomorphous population of cells.

Objectives

To determine the expression of stem cell markers (SOX2, Nestin, CD133) within tumours WDLD, immature PIT-1 lineage and acidophil stem cell tumours, compared with committed cell lineage tumours.

Methods

Retrospective evaluation of surgically resected pituitary tumours from St Vincent’s Hospital, Sydney. Patients were selected to cover a range of tumour types, based on transcription factor and hormone immunohistochemistry. Clinical data was collected from patient files. Radiology reports were reviewed for size and invasion. Samples were analysed by immunohistochemistry and RT-qPCR for SF-1, PIT-1, T-PIT, SOX2, Nestin and CD133. Stem cell markers were compared between tumours WDLD and those with classically “mature” types.

Results

On immunohistochemistry, SOX2 was positive in a higher proportion of tumours WDLD compared with those meeting WHO lineage criteria, 7/10 v 10/42 (70 v 23.4%, p = 0.005). CD133 was positive in 2/10 tumours WDLD but 0/41 meeting lineage criteria, P = 0.003. On RT-qPCR, there was no significant difference in relative expression of stem cell markers (SOX2, CD133, Nestin) between tumours with and WDLD.

Conclusions

Our study is the first to biologically characterise pituitary tumours WDLD. We demonstrate that these tumours exhibit a higher expression of the stem cell marker SOX2 compared with other lineage-differentiated tumours, suggesting possible involvement of stem cells in their development.
Balancing democracy: majoritarianism versus expression of preference intensity
Authors: Nitzan Asaf D. M. , Nitzan Shmuel I.
Published: March 2024

This paper evaluates three prominent voting systems: the Majority Rule (MR), Borda Rule (BR), and Plurality Rule (PR). Our analysis centers on the susceptibilities of each system to potential transgressions of two foundational principles: the respect for majority preference (majoritarianism) and the acknowledgment of the intensity of individual preferences. We operationalize the concept of 'cost' as the expected deviation from the aforementioned principles. A comparative assessment of MR, BR, and PR is undertaken in terms of their costs. Our findings underscore the superiority of PR over MR, whilst also highlighting the comparative advantage of MR against BR.
Are family firms green?
Authors: Miroshnychenko Ivan , Miller Danny , De Massis Alfredo , Le Breton-Miller Isabelle
Published: March 2024

This study examines environmental management practices of 1690 family and nonfamily firms from 29 countries and 19 industrial sectors over an 8-year period. We show that the family effect on firm environmental management practices ranges substantially, from extremely negative to no effect at all. Moreover, the magnitude of the effect depends on the type of firm, the industrial context, the type of economy, and the stages of the business cycle. This study offers a novel understanding of the extreme heterogeneity of environmental management practices of family businesses and serves as a springboard for future research aiming to better understand the environmental strategies of publicly traded firms with concentrated ownership structures. It also provides important and novel evidence for policymakers, investors, and business owners, particularly for firms with different ownership and management structures.

Inequities in urban greenspace have been identified, though patterns by race and socioeconomic status vary across US settings. We estimated the magnitude of the relationship between a broad mixture of neighborhood-level factors and residential greenspace using weighted quantile sum (WQS) regression, and compared predictive models of greenspace using only neighborhood-level, only individual-level, or multi-level predictors. Greenspace measures included the Normalized Difference Vegetation Index (NDVI), tree canopy, and proximity of the nearest park, for residential locations in Shelby County, Tennessee of children in the CANDLE cohort. Neighborhood measures include socioeconomic and education resources, as well as racial composition and racial residential segregation. In this sample of 1012 mother–child dyads, neighborhood factors were associated with higher NDVI and tree canopy (0.021 unit higher NDVI [95% CI: 0.014, 0.028] per quintile increase in WQS index); homeownership rate, proximity of and enrollment at early childhood education centers, and racial composition, were highly weighted in the WQS index. In models constrained in the opposite direction (0.028 unit lower NDVI [95% CI: − 0.036, − 0.020]), high school graduation rate and teacher experience were highly weighted. In prediction models, adding individual-level predictors to the suite of neighborhood characteristics did not meaningfully improve prediction accuracy for greenspace measures. Our findings highlight disparities in greenspace for families by neighborhood socioeconomic and early education factors, and by race, suggesting several neighborhood indicators for consideration both as potential confounders in studies of greenspace and pediatric health as well as in the development of policies and programs to improve equity in greenspace access.
Ginsenoside Rg1 relieves rat intervertebral disc degeneration and inhibits IL-1β-induced nucleus pulposus cell apoptosis and inflammation via NF-κB signaling pathway

Published: March 2024

The study aimed to investigate the effect of ginsenoside Rg1 on intervertebral disc degeneration (IVDD) in rats and IL-1β-induced nucleus pulposus (NP) cells, and explore its underlying mechanism. Forty IVDD rat models were divided into the IVDD group, low-dose (L-Rg1) group (intraperitoneal injection of 20 mg/kg/d ginsenoside Rg1), medium-dose (M-Rg1) group (intraperitoneal injection of 40 mg/kg/d ginsenoside Rg1), and high-dose (H-Rg1) group (intraperitoneal injection of 80 mg/kg/d ginsenoside Rg1). The pathological change was observed by HE and safranin O-fast green staining. The expression of IL-1β, IL-6, TNF-α, MMP3, aggrecan, and collagen II was detected. The expression of NF-κB p65 in IVD tissues was detected. Rat NP cells were induced by IL-1β to simulate IVDD environment and divided into the control group, IL-1β group, and 20, 50, and 100 µmol/L Rg1 groups. The cell proliferation activity, the apoptosis, and the expression of IL-6, TNF-α, MMP3, aggrecan, collagen II, and NF-κB pathway–related protein were detected. In IVDD rats, ginsenoside Rg1 improved the pathology of IVD tissues; suppressed the expression of IL-1β, IL-6, TNF-α, aggrecan, and collagen II; and inhibited the expression of p-p65/p65 and nuclear translocation of p65, to alleviate the IVDD progression. In the IL-1β-induced NP cells, ginsenoside Rg1 also improved the cell proliferation and inhibited the apoptosis and the expression of IL-6, TNF-α, aggrecan, collagen II, p-p65/p65, and IκK in a dose-dependent manner. Ginsenoside Rg1 alleviated IVDD in rats and inhibited apoptosis, inflammatory response, and ECM degradation in IL-1β-induced NP cells. And Rg1 may exert its effect via inhibiting the activation of NF-κB signaling pathway.
Prediction of antioxidant capacity in faba bean from individual phenolic constituents
Authors: Johnson Joel B. , Kazak Anatoliy , Gallini Nadezhda , Rudenko Marina , Naiker Mani
Published: March 2024

The relationship between individual phytochemical constituents and overall antioxidant capacity or total phenolic content (TPC) is poorly understood in faba bean. This study used a range of linear and nonlinear regression techniques to investigate whether the antioxidant capacity and TPC of 60 faba bean samples (flour and methanolic extracts) could be predicted from 12 individual compounds (10 common polyphenols and 2 alkaloid glycosides) measured in the same samples. Nonlinear regression using machine learning with a Radial Basis Function showed the best performance for antioxidant and TPC prediction across all sample types, while multiple linear regression allowed moderately accurate predictions in most sample matrices. Improved performance metrics were seen for the methanolic extracts compared to the flour samples. The strongest predictors of antioxidant activity in the multiple linear regression models were protocatechuic acid, p-hydroxybenzoic acid, and ferulic acid, suggesting that these compounds are particularly important contributors to the high antioxidant activity of faba bean. Understanding the relationship between individual constituents and the antioxidant capacity may help food technologists and plant breeders develop faba bean products with maximal health benefits.

Published: March 2024

The current manuscript addresses fluid–structure interaction (FSI) problems to the analysis of vortex-induced vibration (VIV), employing the methodology designated as IMERSPEC2D. The approach seamlessly integrates the Fourier pseudo-spectral method (FPSM) and the immersed boundary method (IBM) to solve the Navier–Stokes (NS) and continuity equations. Simultaneously, the effects of cylindrical structure, involving 1 and 2 degrees of freedom (d.o.f.) are simulated, by incorporating structural motion equations into NS via the IBM source term and implementing a two-way FSI algorithm. In the paper are presented the comparison of low and high-order temporal integration methods applied to solve the dynamic behavior of the structure and the dimensionless of the cylinder’s structural motion equations, resulting in an increase in computational time step from 1E($$-9$$

). Validation results to refined mesh simulations include the accurate representation of the lock-in phenomenon to simulations of 1 d.o.f. obtaining the range between reduced velocity 5.456 and 5.568 and the maximal amplitude is 0.352. Notably, the eight-shape pattern of the 2 d.o.f. cylinder displacement is obtained and the formation of C2S wake patterns is achieved, as presented by other authors. In conclusion, the dimensionless approach reduces computational time, while the high-order both of IMERSPEC methodology and time advancement integration to FSI improve the results of the cylinder’s motion and alters distinct vortex shedding patterns in fluid dynamics.
Climate change, ESG criteria and recent regulation: challenges and opportunities
Authors: Oliver Yébenes Mónica
Published: March 2024

The application of environmental, social and governance (ESG) criteria has now become a more than essential requirement in the financial world. Therefore, it is necessary to understand, select and assess the risks of these ESG criteria and evaluate how they can impact a product or investment decision. Thus, the main objective of this article is to analyze ESG (Environmental, Social and Governance) indicators and their potential impacts in the framework of non-financial information. Current regulatory developments, such as the European Corporate Sustainability Reporting Directive (CSRD), are pushing to make ESG indicators (within this triple perspective: social, environmental and governance risks) a key set of information to be used for reporters and users of information. This article will study in further detail the main implications these regulations will have in how corporations will reflect social and ecological footprint information in their external reporting. Since these ESG indicators could have relevant financial impacts on the financial drivers of a corporation, stakeholders will be concerned on how enterprises are dealing with these ESG risks. Therefore, this ESG data will increase transparency and would mean a better understanding on how companies and investors have a sustainability compromise to evolve to a neutral carbon economy. In order to understand a company’s commitment with these ESG criteria, stakeholders would have to assess different aspects of the information reported. In this sense, this article will focus on how credit rating agencies incorporate these risks in their assessments. Credit rating agencies are becoming important actors in the sustainability criteria, as they incorporate ESG risks in their assessments, transmitting the importance of these indicators to investors and to markets. This study will look into the different time horizons between financial profitability and sustainability indicators. Current tendency and huge demand of non-financial indicators do not have the same profoundness, framework and tradition as financial indicators. This could lead to a situation in which it would be necessary a period to adapt both worlds and make them join and connect together in a sense in which one need the other one.

Published: March 2024

Concrete has become a versatile material by adapting itself to user needs, from pavers to skyscrapers. Escalated demand for concrete is the prime reason for the exploitation of resources and increased carbon emissions. This research focuses on reducing the environmental impact of cement manufacturing by partly replacing cement with 40% ground granulated blast furnace slag (GGBS) and 20% fly ash (FA). Waste management is also uplifted by fractional replacement of manufactured sand (M-sand) with granulated blast furnace slag (GBFS) at various intervals. Results of mechanical properties prove that this triple-blend M25 concrete with 60% GBFS and 40% M-sand as a fine aggregate would exhibit optimum mechanical properties and a maximum density of 2.58 g/cc. Tests on durability properties assure that, at the same replacement level, the percentage of weight loss due to acid attack was the lowest, with a value of 1.9, and the percentage of weight gain due to sulfate attack was as low as 0.12. The end product obtained with 40% M-sand and 60% GBFS as fine aggregates will be cost-effective and eco-friendly, making triple-blended concrete dense, durable, and sustainable and promoting waste management.
An exploratory analysis of COVID bot vs human disinformation dissemination stemming from the Disinformation Dozen on Telegram
Authors: Ng Lynnette Hui Xian , Kloo Ian , Clark Samantha , Carley Kathleen M.
Published: March 2024

The COVID-19 pandemic of 2021 led to a worldwide health crisis that was accompanied by an infodemic. A group of 12 social media personalities, dubbed the “Disinformation Dozen”, were identified as key in spreading disinformation regarding the COVID-19 virus, treatments, and vaccines. This study focuses on the spread of disinformation propagated by this group on Telegram, a mobile messaging and social media platform. After segregating users into three groups—the Disinformation Dozen, bots, and humans, we perform an investigation with a dataset of Telegram messages from January to June 2023, comparatively analyzing temporal, topical, and network features. We observe that the Disinformation Dozen are highly involved in the initial dissemination of disinformation but are not the main drivers of the propagation of disinformation. Bot users are extremely active in conversation threads, while human users are active propagators of information, disseminating posts between Telegram channels through the forwarding mechanism.
Study of a wall-climbing robot based on chain feet with negative pressure adhesion
Authors: Qian Zhen , Xia Hanbiao
Published: March 2024

In this paper, a wall-climbing robot based on chain feet with negative pressure adhesion is designed. The robot uses chain feet with negative pressure adhesion as the motion units and has the characteristics of adhesion and barrier crossing. Analyzing the power consumption is an important aspect of robot design. The influences of robot design parameters on mechanical characteristics are analyzed with the kinetic method. The robot power model is constructed by combining the energy model of the drive motor and the power model of the transmission system. The relationship between the key parameters and robot power consumption is established by discussing the effects of the robot load, motor angular velocity, and other related design parameters on the robot power consumption. Simulations and experiments show that the established robot power model can be used as a theoretical basis for the optimal design of robots and provides a reference for establishing an optimal model for the motion control of robots.
Frame Selection Using Spatiotemporal Dynamics and Key Features as Input Pre-processing for Video Super-Resolution Models
Authors: Agrahari Baniya Arbind , Lee Tsz-Kwan , Eklund Peter , Aryal Sunil
Published: March 2024

This paper presents a novel approach to video super-resolution (VSR) by focusing on the selection of input frames, a process critical to VSR. VSR methods typically rely on deep learning techniques, those that are able to learn features from a large dataset of low-resolution (LR) and corresponding high-resolution (HR) videos and generate high-quality HR frames from any new LR input frames using the learned features. However, these methods often use as input the immediate neighbouring frames to a given target frame without considering the importance and dynamics of the frames across the temporal dimension of a video. This work aims to address the limitations of the conventional sliding-window mechanisms by developing input frame selection algorithms. By dynamically selecting the most representative neighbouring frames based on content-aware selection measures, our proposed algorithms enable VSR models to extract more informative and accurate features that are better aligned with the target frame, leading to improved performance and higher-quality HR frames. Through an empirical study, we demonstrate that the proposed dynamic content-aware selection mechanism improves super-resolution results without any additional architectural overhead, offering a counter-intuitive yet effective alternative to the long-established trend of increasing architectural complexity to improve VSR results.
Scenario-based tsunami hazard assessment for Northeastern Adriatic coasts
Authors: Peresan Antonella , Hassan Hany M.
Published: March 2024

Significant tsunamis in the Northern Adriatic are rare, and only a few historical events have been reported in the literature, with sources mostly located along central and southern parts of the Adriatic coasts. Recently, a tsunami alert system has been established for the whole Mediterranean area; however, a detailed description of the potential impact of tsunami waves on coastal areas is still missing for several sites. This study aims to model the hazard associated with possible tsunamis generated by offshore earthquakes, with the purpose of contributing to tsunami risk assessment for selected urban areas along the Northeastern Adriatic coasts. Tsunami modelling is performed by the NAMI DANCE software, which allows accounting for seismic source properties, variable bathymetry, and nonlinear effects in wave propagation. Hazard scenarios at the shoreline are developed for the coastal areas of Northeastern Italy and at selected cities (namely, Trieste, Monfalcone, Lignano and Grado). An extensive set of potential tsunamigenic sources of tectonic origin located in three distance ranges (namely at Adriatic-wide, regional and local scales) are considered for the modelling. Sources are defined according to available literature, which includes catalogues of historical tsunamis and existing active faults databases. Accordingly, a set of tsunami-related parameters and maps are obtained (e.g. maximum run-up, arrival times, synthetic mareograms) that are relevant to planning mitigation actions at the selected sites.

Published: March 2024

Background

The high number of confined space incidents in Malaysia suggests that working in a confined space exposes workers to a substantial risk of serious injury or fatality. The rapid development of industry and technology has increased the need to work in confined spaces and significantly impacted the risk management of confined spaces. Utilizing past incident data through investigation will help develop risk management and preventive measures related to confined spaces. As a result, this paper will conduct a fatal incident investigation associated with confined spaces from 2010 to 2020 in Malaysia.

Methodology

The incident investigation uses the improved systematic casual analysis technique (SCAT) to identify the immediate cause and the direct cause. From the identified fatal incidents immediate causes, the study will highlight the main hazard that causes fatal incidents in confined spaces. The preventive measure is developed based on the main hazard of confined spaces that cause fatalities.

Result

The result of the study has identified that physical and atmospheric hazards are the main factors that cause fatal incidents associated with confined spaces in Malaysia. Moreover, from the SCAT checklist, the study has revealed that failing to use PPE properly and hazardous environmental conditions are the main immediate cause of fatal incidents in confined spaces.

Conclusion

Effective risk management of confined spaces, with a particular focus on addressing atmospheric and physical hazards, is crucial for preventing accidents, especially those incidents resulting in fatalities. Future studies should expand their focus to include injuries and near-miss events in confined spaces, aiming to develop more effective and inclusive safety measures by analyzing a broader range of incidents.

Agroforestry plays a pivotal role in mitigating greenhouse gas (GHG) emissions and addressing the challenges posed by climate change. While carbon sequestration efforts have primarily centred on forests, it is imperative to acknowledge the contribution that non-forest ecosystems, such as agroforestry, can offer. This study investigated the influence of agroforestry systems on the variation of biomass carbon stocks in the Sahelo-Sudanian and Sudanian regions of the Senegalese Groundnut basin. Three primary agroforestry systems were studied: silvopastoral, agrisilvicultural, and agrosilvopastoral. Forty-six (46) 100 m × 100 m plots were sampled, within which 1 × 1 m2 subplots were used to sample understory biomass across three agroforestry systems in the two climatic zones. Analysis of variance was performed to assess the influence of agroforestry systems and climatic zones on biomass carbon stocks. The findings showed that in the Sahelo-Sudanian region, the agrisilvicultural system exhibited the highest AGC + BGC stocks, averaging 43.42 ± 21.61 tCha−1. In contrast, the silvopastoral system showed significantly higher AGC + BGC stocks, which amounted to 36.33 ± 12.27 tCha−1 in the Sudanian region. On the other hand, understory carbon stocks were significantly higher (p < 0.01) in the agrisilvicultural and agrosilvopastoral systems than in the silvopastoral system in both climatic zones. Agroforestry systems had a significant effect on AGC + BGC stocks within climatic zones. Nevertheless, the effect was less pronounced when comparing across climatic regions. These results underscore the importance of specific land management practices interacting with local climatic conditions to influence AGC + BGC stocks. Therefore, policy makers should carefully consider the interaction of these factors when implementing carbon management practices and planning mitigation strategies in West Africa.
Opportunities and challenges for the use of deep brain stimulation in the treatment of refractory major depression
Authors: Unadkat Prashin , Quevedo Joao , Soares Jair , Fenoy Albert
Published: March 2024

Major Depressive Disorder continues to remain one of the most prevalent psychiatric diseases globally. Despite multiple trials of conventional therapies, a subset of patients fail to have adequate benefit to treatment. Deep brain stimulation (DBS) is a promising treatment in this difficult to treat population and has shown strong antidepressant effects across multiple cohorts. Nearly two decades of work have provided insights into the potential for chronic focal stimulation in precise brain targets to modulate pathological brain circuits that are implicated in the pathogenesis of depression. In this paper we review the rationale that prompted the selection of various brain targets for DBS, their subsequent clinical outcomes and common adverse events reported. We additionally discuss some of the pitfalls and challenges that have prevented more widespread adoption of this technology as well as future directions that have shown promise in improving therapeutic efficacy of DBS in the treatment of depression.

Modern Linguistics in Ancient India
Authors: Lowe John J.
Published: March 2024

The ancient Indian linguistic tradition has been influential in the development of modern linguistics, yet is not well known among modern Western linguists. This unique book addresses this gap by providing an accessible introduction to the Indian linguistic tradition, covering its most important achievements and ideas, and assessing its impact on Western linguistics. It shows how ancient Indian methods of linguistic analysis can be applied to a number of topical issues across the disciplines of modern linguistics–spanning phonetics, phonology, morphology, syntax, semantics, and computational linguistics. Exploring the parallels, differences, and connections in how both traditions treat major issues in linguistic science, it sheds new light on a number of topical issues in linguistic theory. Synthesizing existing major work on both sides, it makes Indian linguistics accessible to Western linguists for the first time, as well as making ideas from mainstream linguistics more accessible to students and scholars of Indian grammar.

Women's Genealogies in the Medieval Literary Imagination
Authors: Bérat Emma O.
Published: March 2024

Uncovering the many striking female alternatives to patrilineal narratives in medieval texts, Emma O. Bérat explores strategies of writing and illustration that creatively and purposefully depict women's legacies. Genealogy, used to justify a character's present power and project it onto the future, was crucial to medieval political, literary, and historical thought. While patrilineage often limited women to exceptional or passive roles, other genealogical forms that represent and promote women's claims are widespread in medieval texts. Female characters transmit power through book patronage and reading, enduring landmarks, and international travel, as well as childbearing and succession. These flexible – if messy – genealogies reflect the web of political, biological, and spiritual relations that frequently characterized elite women's lives. Examining hagiography, chronicles, genealogical rolls, and French, English, and Latin romances, as well as associated codices and images, Bérat highlights the centrality of female characters and historical women to this fundamental aspect of medieval consciousness.
A Historical Review of Swedish Strategy Research and the Rigor-Relevance Gap
Authors: Kalling Thomas , Bengtsson Lars
Published: March 2024

There are many explanations for the so-called rigor-relevance gap in academic research on strategic management. This Element reviews the existing literature on the matter and argues that it must go beyond the typical explanations of knowledge and language differences and look at more fundamental, societal, and cultural explanations. The empirical focus of this Element is the history and possible particularities of strategic management research in Sweden where the authors show how almost 300 years of relevance-centered research have undergone significant changes over the last 30 years, and that the historical development is based very much on societal pressure, academic culture and shifting perspectives on the role of academic research. The authors conclude by offering a couple of examples of how Swedish research, close to its traditional approaches, still can contribute to relevance and thus help balance the rigor-relevance divide.
The Two Noble Kinsmen
Authors: Shakespeare William
Published: March 2024

The New Cambridge Shakespeare appeals to students worldwide for its up-to-date scholarship and emphasis on performance. The series features line-by-line commentaries, textual notes on the plays and poems and an extensive Introduction. Since the late twentieth century, when scholarly attention began to focus on sexuality, collaboration and Shakespeare's late plays, The Two Noble Kinsmen has become an essential script. Turner and Tatspaugh's edition presents a strong case for taking the play more seriously now than ever before. A lively introduction discusses Shakespeare's craftsmanship in adapting a medieval tale for the Jacobean stage, the extent of co-authorship with John Fletcher, the rhetorical complexity of Shakespeare's late style, the themes of sexuality and friendship, and contemporary critical responses to the play. The edition demonstrates the theatrical vitality of The Two Noble Kinsmen and confirms it as a play for today.

Published: March 2024

We evaluated the secondary COVID-19 incidence among uninfected hospitalized patients after nosocomial COVID-19 exposure. An exposure source of SARS-CoV-2 was hospitalized patients or healthcare personnel (HCP) newly diagnosed as having COVID-19. Patients exposed to a COVID-19-infected patient in a shared room more frequently developed COVID-19 than those exposed to an infected HCP.
Yegiazaryan v. Smagin (U.S. Sup. Ct.)
Authors: Gomez-Moreno Juan Pablo
Published: March 2024

Yegiazaryan v. Smagin represents a landmark case within the Supreme Court's (SCOTUS) jurisdiction, revolving around a contractual dispute between John Yegiazaryan and Alex Smagin. The legal intricacies unfolded when Smagin sought to enforce a multimillion-dollar arbitration award against Yegiazaryan in California under the New York Convention. The district court's asset freeze faced complications as Yegiazaryan, residing in California, received an unrelated arbitration award and attempted to evade the freeze. In response, Smagin invoked the Racketeer Influenced and Corrupt Organizations Act (RICO), alleging a coordinated effort to obstruct the collection of the arbitration judgment. The case stands as a pivotal legal milestone marked by complexities and jurisdictional challenges.
Stability of a photosurfactant-laden viscous liquid thread under illumination
Authors: Mayer Michael D. , Kirk Toby L. , Papageorgiou Demetrios T.
Published: March 2024

This paper investigates the effects of a light-actuated photosurfactant on the canonical problem of the linear stability of a viscous thread surrounded by a dynamically passive fluid. A model consisting of the Navier–Stokes equations and a set of molar concentration equations is presented that capture light-induced switching between two stable surfactant isomer states, trans and cis. These two states display significantly different interfacial properties, allowing for some external control of the stability behaviour of the thread via incident light. Normal modes are used to generate a generalized eigenvalue problem for the growth rate which is solved with a hybrid analytical and numerical method. The results are validated with appropriate analytical solutions of increasing complexity, beginning with a solution to a clean interface, then analytical solutions for one insoluble surfactant, one soluble surfactant and a special case of two photosurfactants with a spatially uniform undisturbed state. Presenting each of these cases allows for a holistic discussion of the effect of surfactants in general on the stability of a liquid thread. Finally, the numerical solutions in the presence of two photosurfactants that display radially non-uniform undisturbed states are presented, and details of the impact of the illumination on the linear stability of the thread are discussed.
Canonical decompositions and algorithmic recognition of spatial graphs
Authors: Friedl Stefan , Munser Lars , Quintanilha José Pedro , Santos Rego Yuri
Published: March 2024

We prove that there exists an algorithm for determining whether two piecewise-linear spatial graphs are isomorphic. In its most general form, our theorem applies to spatial graphs furnished with vertex colourings, edge colourings and/or edge orientations.

We first show that spatial graphs admit canonical decompositions into blocks, that is, spatial graphs that are non-split and have no cut vertices, in a suitable topological sense. Then, we apply a result of Haken and Matveev in order to algorithmically distinguish these blocks.
On the moduli of hypersurfaces in toric orbifolds

We construct and study the moduli of stable hypersurfaces in toric orbifolds. Let X be a projective toric orbifold and $\alpha \in \operatorname{Cl}(X)$ an ample class. The moduli space is constructed as a quotient of the linear system $|\alpha|$ by $G = \operatorname{Aut}(X)$. Since the group G is non-reductive in general, we use new techniques of non-reductive geometric invariant theory. Using the A-discriminant of Gelfand, Kapranov and Zelevinsky, we prove semistability for quasismooth hypersurfaces of toric orbifolds. Further, we prove the existence of a quasi-projective moduli space of quasismooth hypersurfaces in a weighted projective space when the weighted projective space satisfies a certain condition. We also discuss how to proceed when this condition is not satisfied. We prove that the automorphism group of a quasismooth hypersurface of weighted projective space is finite excluding some low degrees.
Ethnography in War and Peace
Authors: Suni Anoush Tamar
Published: March 2024

What is ethnography in times of war? How does war shape the conditions and possibilities of ethnographic research? How do the exigencies of daily life in a war zone ultimately prescribe and restrict what kinds of research can be done? In the following essay, I reflect on my experiences conducting ethnographic fieldwork in southeastern Turkey in unexpected wartime conditions. During the two years that I spent in the field, a series of local and national crises disrupted a fragile peace that had lasted for the previous few years. Confronted with disaster after disaster, I was continually compelled to reevaluate my project—interrogating my research questions, changing my research methods, and assessing whether I would be able to continue my research at all. The war defined my time in the field and dictated the possibilities and limitations of the work that I was able to do. While I had planned to examine earlier histories of violence, ultimately the contemporaneous war and its effects on daily life, the politics of memory, and the landscape became a central focus of my fieldwork.
“Why Is America Interested in Islam in Turkey?”: Fieldwork and Problems of Gaining Trust in a Low-Trust Society
Authors: Ozgen Zeynep
Published: March 2024

When researchers think of access disruptions, they tend to think of factors exogenous to a field site, those emerging from nationwide events or global crises. Especially in semiauthoritarian contexts, such as Turkey, where ongoing historical contestations (over human rights, minority rights, and freedom of expression) as well as current political polarizations have created a volatile institutional and social environment, ethnographers are more likely to find their fieldwork disrupted. In this essay, I draw attention to a different kind of disruption, one that arises from the endogenous character of the local field site. In particular, I discuss the impact of low interpersonal trust on fieldwork. While gaining access and establishing trust are universal challenges in ethnographic research, the issue is particularly a formidable one in Turkey.
Orders and Disorders of Marriage, Church, and Empire in Mid-Nineteenth-Century Ottoman Armenia
Authors: Derderian Dzovinar
Published: March 2024

The Ottoman state and the Armenian Patriarchate of Constantinople during the mid-19th-century Tanzimat reform era relied on ethno-confessional and gendered differences, new administrative organization, and coercive institutions like the police to centralize and expand their power. Yet Armenian men and women used those same tools of power to seek justice in ways that created instances of disorder for their families, local community, the church, and the Ottoman state. Attending to the voices and experiences of Armenians through untapped petitions from Erzurum, Mush, and Van, this article highlights the ways in which provincial Armenians interacted with and navigated their diverse ethno-confessional milieus.
Sub-Urban or Post-Rural: Suburban Development as a Two-Way Street in the Mid-Twentieth Century
Authors: CONN STEVEN
Published: March 2024

This article argues that because a center–periphery model has dominated our understanding of postwar suburban growth we have failed to fully understand the rural dimensions of that growth. That misunderstanding resulted from the urban orientation of sociologists who studied the suburbs. As a consequence, we have also not appreciated the extent to which rural political outlooks shaped the postwar backlash against New Deal liberalism in the suburbs.
Feeling Responsible: On Regret for Others’ Harms
Authors: Ferguson Magnus
Published: March 2024

This paper investigates the moral emotion of being socially, but non-agentially connected to a harm. I propose understanding the emotion of an affiliated onlooker as a species of regret called ‘social-regret’. Breaking from existing guilt- and shame-based accounts, I argue that social-regret can be a fitting, expressive, and revelatory reactive attitude that opens the way for deliberation over accountability for others’ harms. When we feel social-regret, our attention is directed towards the moral salience of our social relations and the expectations that undergird them, as well as possibilities for ameliorative action. I consider several existing accounts of affiliated onlookers’ emotions (including embarrassment, guilt, and shame), and I highlight the advantages of supplementing these with a regret-based account. Social-regret provides a novel way to understand negative, self-directed emotions in response to others’ harms as rational, expressive, and potentially reason-giving experiences.
A longitudinal investigation of caregiving and adolescent post-traumatic stress symptoms during COVID-19: evidence for high resting RSA as a susceptibility factor

Background

Post-traumatic stress symptoms (PTSS) were the most frequently reported mental health concern for youth during COVID-19, yet variations in youth's PTSS responses warrant empirical consideration. Features of the caregiving environment influence youth's responses to environmental stressors, and youth's parasympathetic nervous system regulation may qualify the magnitude and/or direction of these effects. This prospective investigation evaluated diathesis stress and differential susceptibility models of caregiving and parasympathetic influences on youth's PTSS responses to COVID-19.

Method

Participants were 225 caregiver-youth dyads (youth 49.8% female at birth; 88.4% non-white) followed from childhood through adolescence and COVID-19. Youth's resting respiratory sinus arrhythmia (RSA; Mage = 6.11, s.d. = 0.21), caregiving features (i.e. attachment security [youth Mage = 12.24, s.d. = 0.35] and caregiver internalizing psychopathology [caregiver Mage = 39.29, s.d. = 6.78]) were assessed pre-pandemic. Youth's PTSS was assessed one year prior to the US COVID-19 pandemic (Mage = 14.24, s.d. = 0.50) and during the spring of 2020 at the height of the pandemic (Mage = 15.23, s.d. = 0.57).

Results

Youth's PTSS increased during COVID-19. Youth with relatively high resting RSA evidenced the lowest PTSS when their caregiving environment featured high attachment security or low caregiver internalizing problems, but the highest PTSS when their caregiving environment featured low attachment security or high caregiver internalizing problems. In contrast, PTSS levels of youth with relatively low or average resting RSA did not differ significantly depending on attachment security or caregiver internalizing.

Conclusions

Results are consistent with a differential susceptibility hypothesis, wherein relatively high resting RSA conferred heightened sensitivity to caregiving environments in a for-better-and-for-worse manner during COVID-19.
From Labor Sit-Downs to Civil Rights Sit-Ins: A Genealogy of Liberal Civil Disobedience
Authors: Scheuerman William E.
Published: March 2024

Liberal views of civil disobedience that emerged in the 1960s and ’70s can only be properly interpreted with recourse to the complicated history of the early civil rights movement's selective appropriation of the labor sit-downs of the 1930s. This essay addresses the messy but basically successful effort by civil rights sit-inners and the lawyers who defended them to circumvent the repressive state and legal response—especially the US Supreme Court ruling in National Labor Relations Board v. Fansteel Metallurgical Corporation (1939)—that the 1930s sit-downers garnered. My reexamination of the sit-ins places influential liberal ideas about civil disobedience in a fresh light. In his influential theory of civil disobedience, John Rawls mirrored key features of the politically and legally savvy strategy of delinking the lunch counter sit-ins from the workplace sit-downs. The result was a somewhat restrictive view of civil disobedience that sidelined matters of economic justice.
Thomas Aquinas's Political Science: Philosophy or Theology?
Authors: Waldorf Steven
Published: March 2024

This article examines whether Aquinas's political science is philosophy or theology, a question that arises from his understanding of happiness. If the supernatural vision of God constitutes perfect beatitude or the ultimate end, then how can an account of imperfect happiness—political virtue—be given without reference to it and hence without appeal to revealed theology? I argue that Aquinas provides a strictly philosophical account of imperfect happiness by showing that, among temporal goods, virtue most fully instantiates general attributes of beatitude such as self-sufficiency and continuity, even though it does not perfectly instantiate them. This way of demonstrating the superiority of virtue to other temporal goods requires no appeal to supernatural beatitude, and thus political science, which takes this imperfect happiness as its first principle, is philosophy.
