Optimizing kerf quality in high-speed WEDM of thin woven CFRP composites: a taguchi, WASPAS, and PSO approach
Authors: Eisa Abeer , AbouHawa Mohamed , Fattouh Mohamed
Published: October 2024

The process of machining CFRP composites presents unique challenges, particularly in the context of WEDM. The inherent properties of CFRP composites, such as their low electrical conductivity, anisotropic nature, and heterogeneous composition, require further research to enhance their machinability through WEDM techniques. This study examines the enhancement of kerf characteristics such as kerf width (Wk), delamination factor (DFK), and cutting speed (CSK) in thin woven 0°/90° CFRP composites using high-speed WEDM. A Taguchi L16 experimental analysis was employed to analyze the impact of key process parameters, including pulse-on (Pon), pulse-off (Poff), and input current (I), in conjunction with CFRP parameters such as the CFRP thickness (T) and cutting direction on the kerf characteristics. The CFRP thickness ranged from 0.5 to 2.0 mm, and the cutting directions studied were horizontal and inclined 30° cuts. A multiple-response optimization strategy using the CRITIC-WASPAS approach coupled with a particle swarm optimization (PSO) algorithm were applied to identify the ideal process combination for various CFRP thicknesses. The findings indicated that the CFRP thickness, pulse-off time, and input current are the most statistically significant factors influencing the overall kerf characteristics. The cutting direction has a negligible effect on the kerf width but has conflicting effects on the delamination factor and cutting speed. Specifically, a horizontal cut decreases delamination, whereas an inclined 30° cut is preferable for achieving higher cutting speeds. For precise kerf cutting, optimal process combinations were determined: Pon (30 µs), Poff (30 µs), and I (ranging from 4 to 5 A) for 0.5 mm CFRP thickness, and Pon (30 µs), Poff (15 µs), and varying input currents of 4 A, ranging from 4 to 3 A, and 3 A for CFRP thicknesses of 1.0, 1.5, and 2.0 mm, respectively.

Authors: Yasobant Sandul , Tadvi Ravina , Bruchhausen Walter , Saxena Deepak B.
Published: October 2024

An effective disease surveillance system can detect outbreaks of emerging zoonotic diseases early and allow the system to respond immediately and control the epidemic. Gujarat is a western Indian state with a population of more than 65 million humans and 26 million livestock, and it has the respective surveillance systems under the Department of Health & Family Welfare for humans and the Department of Animal Husbandry for animals. A veterinarian is placed on establishing cross-sectoral collaborations between these systems, but the joint collaborative activities and their effect on the early warning response are least understood. This provides an opportunity to conduct a secondary policy content analysis study using the One Health Surveillance Matrix (OHSM). The aim of this study was to evaluate the level of collaboration among human-animal disease surveillance systems for zoonotic disease in Gujarat, India. This study findings highlight a few gaps in the human health surveillance system, such as data sharing, sampling, outreach to decision-makers, and external communication, while the animal health surveillance system exhibits deficiencies in the data dissemination to decision-makers, management and storage of data analysis, interpretation of data, and external communication as per the OHSM evaluation. Despite major differences, there is a possibility of developing the One Health Surveillance system in Gujarat, India which is profoundly documented in this study.
Brassinolides signaling pathway: tandem response to plant hormones and regulation under various abiotic stresses
Authors: Gao Yanlong , Ma Xiaolan , Zhang Zhongxing , Wang Xiaoya , Wang Yanxiu
Published: October 2024

Plant hormones play pivotal roles in stress responses by modulating growth, development, stomatal movement, and the expression of stress-related genes, thereby aiding plants in adapting to and managing various environmental challenges. Each hormone exhibits distinct functions and regulatory mechanisms in stress response, with potential complex interactions among them. Brassinosteroids (BRs) represent a novel hormone that influences the expression of its target genes through a series of phosphorylated cascade reactions involving various transcription factors. This signaling pathway regulates diverse growth and development processes in plants. Additionally, BRs interact with other hormones to modulate physiological development. This review examines BRs biosynthesis and metabolism, elucidates the interactions between BRs and abscisic acid (ABA), jasmonic acid (JA), and gibberellins (GA), and explores their roles in regulating responses to drought, salt, cold, and heat. The review underscores the importance of BRs and other hormonal crosstalk in managing nutrient stress, which is vital for understanding plant growth regulation, enhancing crop stress resistance, advancing biotechnology applications, and furthering plant science research. Future research directions and the potential of BRs production and application to improve plant stress resilience are also discussed in the context of current findings.

Published: October 2024

We employed an interrupted time series analysis to assess the impact of changing electronic medical records, concurrent with a Catheter-Associated Urinary Tract Infection (CAUTI) Taskforce, on CAUTI rates. We found that rates increased in most ICUs before returning to baseline. These findings suggest that a multi-faceted approach may reduce CAUTI rates.

Published: October 2024

Objectives:

We evaluated SARS-CoV-2 anti-nucleocapsid (anti-N) seroconversion and seroreversion rates, risk factors associated with SARS-CoV-2 seroconversion, and COVID-19 risk perceptions among academic healthcare center employees in a rural state.

Methods:

Among employees aged ≥18 years who completed a screening survey (n = 1,377), we invited all respondents reporting previous COVID-19 (n = 85; 82 accepted) and a random selection of respondents not reporting previous COVID-19 (n = 370; 220 accepted) to participate. Participants completed surveys and provided blood samples at 3-month intervals (T0, T3, T6, T9). We used logistic regression to identify risk factors for seropositivity at T0.

Results:

The cohort was primarily direct patient caregivers (205/302; 67.9%), white (278/302; 92.1%), and female (212/302; 70.2%). At T0, 86/302 (28.4%) participants were seropositive. Of the seronegative participants, 6/198 (3.0%), 6/183 (3.3%), and 14/180 (7.8%) had seroconverted at T3, T6, and T9, respectively. The overall seroreversion rate was 6.98% at T9. At T0, nursing staff (odds ratio [OR], 2.37; 95% confidence interval [CI], 1.08, 5.19) and being within six feet of a non-household member outside of work (OR, 2.91; 95% CI, 1.02, 8.33) had significantly higher odds of seropositivity. Vaccination (OR, 0.05; 95% CI, 0.02, 0.12) and face mask use (OR, 0.36; 95% CI, 0.17, 0.78) were protective.

Conclusions:

The seroconversion and seroreversion rates were low among participants. Public health and infection prevention measures implemented early in the COVID-19 pandemic – vaccination, face mask use, and social distancing – were associated with significantly lower odds of SARS-CoV-2 seropositivity among participants.

Biotechnology, with its vast potential, is poised to revolutionize fields ranging from medicine and healthcare to environmental sensing. Central to this revolution are bio-interfaces, which include both electrical and non-electrical interventions using wearables and implants. These interfaces offer new avenues for monitoring and interacting with biological systems, thereby enhancing the capabilities of modern healthcare solutions. The adoption of innovative design strategies is crucial for fully harnessing this potential and overcoming current limitations. In the realm of medicine and healthcare, biotechnology design strategies can bring about significant breakthroughs in disease diagnosis, treatment and prevention. For instance, targeted drug delivery systems can improve treatment efficacy while minimizing side effects. Personalized medicine, made possible through advancements in genomics and proteomics, can tailor treatments to individual patients, leading to better outcomes and reduced healthcare costs.
BioForms: 3-D printed mycelium wall panel systems
Authors: Alima Natalie
Published: October 2024

BioForms integrates sacrificial formworks, agent-based computational algorithms and biological growth in the generation of biodegradable internal wall panel systems. These wall panel systems are intended to minimize material waste, utilize local botany and generate a symbiosis between the artificially made and the naturally grown. This is achieved by utilizing local waste as a structural compressive core, mycelium as the binder, and recycled pellets as the architectural skin. Leveraging mycelium’s structural, acoustic and thermal properties, this exploration delves into unique methods of incorporating fungi and waste into architectural construction. The motivations for this research stem from the need to address the building industry’s contribution to climate change, by considering the lifecycle of our materials. BioForms aims to retrofit existing buildings by replacing foam insulation and MDF (medium-density fiberboard) wall panels with biodegradable and recyclable 3D-printed skins embedded with a mycelium core. Analysing mycelium’s reaction to BioForms I, the second iteration, BioForms II, evolves in design complexity and materiality. BioForms II explored robotically fabricated wood-based polylactic acid plastic (PLA) composite materials. Within the second iteration of this research stream, mycelia was both embedded within the compressed fabricated skins and on the external surface. Whilst BioForms explored the generation of biodegradable wall panel systems, the broader aims of this research is aimed at infiltrating biological matter into human-occupied spaces, completely omitting the use of synthetic building materials within the construction industry and advancing the architects relationship to nature in the generation of form.
The uneven deployment of algorithms as tools in government: evidence from the use of an expert system
Authors: Whitford Andrew B. , Whitford Anna M.
Published: October 2024

While governments have long discussed the promise of delegating important decisions to machines, actual use often lags. Consequently, we know little about the variation in the deployment of such delegations in large numbers of similar governmental organizations. Using data from crime laboratories in the United States, we examine the uneven distribution over time of a specific, well-known expert system for ballistics imaging for a large sample of local and regional public agencies; an expert system is an inference engine joined with a knowledge base. Our statistical model is informed by the push-pull-capability theory of innovation in the public sector. We test hypotheses about the probability of deployment and provide evidence that the use of this expert system varies with the pull of agency task environments and the enabling support of organizational resources—and that the impacts of those factors have changed over time. Within this context, we also present evidence that general knowledge of the use of expert systems has supported the use of this specific expert system in many agencies. This empirical case and this theory of innovation provide broad evidence about the historical utilization of expert systems as algorithms in public sector applications.
Medical Records in Field Operations: A No-Code Approach
Authors: Wilkinson Thomas M.
Published: October 2024

Commercial Electronic Health Record (EHR) systems in the U.S. are hospital-centric and are optimized for billing and insurance processes and liability risk management. Operational medicine has completely different medical record requirements, with dynamic and unpredictable environments and a focus on field triage, emergent patient needs, logistical coordination, and ultimately, the efficient transfer of care. The DHS Office of Health Security’s Medical Information Exchange (MIX) and the DHA’s Joint Operational Medicine Information Systems (JOMIS) programs have been exploring EHR solutions which anticipate and support the multilateral collaborations and fluid circumstances of field-based medical care using a no-code (drag and drop) solution that can be tailored to requirements in real time, can scale down to mobile devices, and can retain full functionality even while offline.

Published: October 2024

This article outlines a human-centered approach to developing digital patient stories, for sharing their experiences in health care, while preserving patient and others’ privacy. Employing a research-through-design approach, the study proposes a design solution using visualization and digital storytelling to document patients’ and families’ experiences and emotions, as well as their interactions with healthcare professionals in the postnatal unit. By transforming selected observational data into animated stories, this approach has the potential to elicit empathy, stimulate stakeholder engagement, and serve as a practical training tool for clinicians. This work was conducted as part of a broader study that aims to contribute to the existing knowledge base by advancing our understanding of stakeholder needs in birthing facilities and through postpartum discharge. This study primarily focuses on strategies for the development of digital stories and summarizes the factors that contributed to the production of digital stories within the context of sensitive data. It may serve as a valuable resource for students, researchers and practitioners interested in utilizing digital stories to encourage discussions, education and ultimately to enhance systems of health care for respect, equity and support.
Melting and solidification in periodically modulated thermal convection
Authors: Yang Rui , Chong Kai Leong , Liu Hao-Ran , Verzicco Roberto , Lohse Detlef
Published: October 2024

Melting and solidification in periodically time-modulated thermal convection are relevant for numerous natural and engineering systems, for example, glacial melting under periodic sun radiation and latent thermal energy storage under periodically pulsating heating. It is highly relevant for the estimation of melt rate and melt efficiency management. However, even the dynamics of a solid–liquid interface shape subjected to a simple sinusoidal heating has not yet been investigated in detail. In this paper, we offer a better understanding of the modulation frequency dependence of the melting and solidification front. We numerically investigate periodic melting and solidification in turbulent convective flow with the solid above and the melted liquid below, and sinusoidal heating at the bottom plate with the mean temperature equal to the melting temperature. We investigate how the periodic heating can prevent the full solidification, and the resulting flow structures and the quasi-equilibrium interface height. We further study the dependence on the heating modulation frequency. As the frequency decreases, we found two distinct regimes, which are ‘partially solid’ and ‘fully solid’. In the fully solid regime, the liquid freezes completely, and the effect of the modulation is limited. In the partially solid regime, the solid partially melts, and a steady or unsteady solid–liquid interface forms depending on the frequency. The interface height can be derived based on the energy balance through the interface. In the partially solid regime, the interface height oscillates periodically, following the frequency of modulation. Here, we propose a perturbation approach that can predict the dependency of the oscillation amplitude on the modulation frequency.
On the kinetics of internal gravity waves beyond the hydrostatic regime
Authors: Labarre Vincent , Lanchon Nicolas , Cortet Pierre-Philippe , Krstulovic Giorgio , Nazarenko Sergey
Published: October 2024

We present a new derivation of the kinetic equation for weak, non-hydrostatic internal gravity wave turbulence. The equation is equivalent to the one obtained by Caillol & Zeitlin (Dyn. Atmos. Oceans, vol. 32, issue 2, 2000, pp. 81–112), but it takes a canonical form. We show that it conserves the energy without involving the resonance condition in frequency, and look for the isotropic part of the steady, scale-invariant solutions. We provide a parametrization of the resonant manifold of non-hydrostatic internal gravity wave triadic interactions. This allows us to simplify the collision integral, and to evaluate the transfer coefficients of all triadic interactions. In the hydrostatic limit, our equation is equivalent to the Hamiltonian description of Lvov & Tabak (Phys. Rev. Lett., vol. 87, issue 16, 2001, 168501).
Scaling behaviour of rotating convection in a spherical shell with different Prandtl numbers
Authors: Fan Wei , Wang Qi , Lin Yufeng
Published: October 2024

Rayleigh–Bénard convection in a rotating spherical shell provides a simplified model for convective dynamics of planetary and stellar interiors. Over the past decades, the problem has been studied extensively via numerical simulations, but most previous simulations set the Prandtl number

$Pr$

to unity. In this study we build more than 200 numerical models of rotating convection in a spherical shell over a wide range of

$Pr$

(

$10^{-2}\le Pr \le 10^2$

). By increasing the Rayleigh number

$Ra$

, we characterise four different flow regimes, starting from the linear onset to multiple modes, then transitioning to the geostrophic turbulence and eventually approaching the weakly rotating regime. In the multiple modes regime, we show evidence of triadic resonances in numerical models with different

$Pr$

, which may provide a generic mechanism for the transition from laminar to turbulence in rotating convection. We analyse scaling behaviours of the heat transfer and convective flow speeds in numerical simulations, paying particular attention to the

$Pr$

dependence. We find that the so-called diffusion-free scaling for the heat transfer cannot reconcile all numerical models with different

$Pr$

in the geostrophic turbulence regime. However, the characteristic flow speeds at different

$Pr$

roughly follow a unified scaling that can be described by visco-Archimedean–Coriolis force balances, though the scaling tends to approach the Coriolis-inertial-Archimedean force balance at low

$Pr$

. We also show that transition behaviours from rotating to non-rotating convection depend on

$Pr$

. The transition criteria based on heat transfer and flow morphology would be rather different when

$Pr>1$

, but the two criteria are consistent for cases with

$Pr\le 1$

. Both scaling behaviours and transition behaviours suggest that the heat transfer is controlled by the boundary layers while the convective flow speeds are mainly determined by the force balance in the bulk for cases with

$Pr>1$

, which is in line with recent experimental results with moderate to high

$Pr$

. For cases with

$Pr \le 1$

, both the heat transfer and convective velocities are approaching the inviscid dynamics in the bulk. We also briefly analysed the magnitude and scaling of zonal flows at different

$Pr$

, showing that the zonal flow amplitude rapidly increases as

$Pr$

decreases.
The relationship among optimism, self-efficacy, occupational compromise, and happiness among young people in the post-Covid-19 period
Authors: Shamir-Balderman Orit , Shmuel Haim , Litaim Mata
Published: October 2024

The current study examined how happiness is affected by optimism, self-efficacy, and occupational compromise (OC), among young workers (aged 20–30 years) in the post-Covid-19 pandemic period. A sample of 211 young people (aged 20–30 years) who were currently or formerly employed participated in the study. The research findings indicate negative correlations between (a) the optimism and self-efficacy of the employees to their OC and (b) between their OC to their sense of happiness. In addition, as hypothesized, positive correlations were found between (a) feelings of optimism and self-efficacy to the degree of happiness and (b) between optimism and self-efficacy. Finally, the study tested a mediation model that indicated optimism as a mediating variable in the relationships of self-efficacy and OC with happiness. In light of these findings, several conclusions emerged from the study. First, according to general trends in the Israeli economy, even among young workers, who make up the new generation of workers in the post-Covid-19 period, there is a reduction in the degree of OC in order to achieve happiness. But this depends on several personality elements, such as their feelings of optimism and self-efficacy. Second, in accordance with the mediation model tested in the study, it seems that optimism has a central role in enhancing happiness among young workers in the post-Covid-19 era, at the beginning of their career path. Eventually, it appears that the reduced OC and elevated happiness among young workers in the post-pandemic period, has the potential to shape the future job market as filled with content employees that can also improve their organizations’ economic output.
To what extent do sea-ice algae affect the modelled transmittance of photosynthetically active radiation (PAR) to the ice-ocean interface?
Authors: Redmond Roche Benjamin H. , King Martin D.
Published: October 2024

Photosynthetically active radiation (PAR) at the ice-ocean interface is critical for primary production. The value of PAR is affected by the thickness of snow and sea ice, with additional absorbers (e.g. algae) further attenuating PAR. Sea-ice algae exhibit a substantial geo-temporal variance in column-integrated concentration (0–500 mg chl-a m−2) and are typically present within the bottom 0.01–0.2 m of sea ice. PAR transmittance is affected by algae concentrations and vertical thicknesses of ice algal layers. Small column-integrated concentrations of chl-a (~<10 mg chl-a m−2) have a negligible effect on the value of PAR transmittance, and large column-integrated concentrations of chl-a (~>10 mg chl-a m−2) can significantly reduce the value of PAR transmittance. Large column-integrated concentrations of chl-a need consideration when calculating PAR transmittance in areas of high sea-ice algae biomass (e.g. the ‘interior’ shelves of the Arctic Ocean, the Canadian Arctic and Antarctica).
Indigenous Diffuse Support and Descriptive Representation in the Canadian House of Commons
Authors: Midzain-Gobin Liam , Snagovsky Feodor , Cowie Chadwick
Published: October 2024

Do Indigenous peoples in present-day Canada display lower levels of diffuse support than non-Indigenous settlers? Given settler colonial relations (both historic and contemporary) and Indigenous peoples’ own political thought, we can expect that Indigenous peoples would have even lower perceptions of state legitimacy than non-Indigenous peoples. However, there are conflicting expectations regarding whether the descriptive representation of Indigenous peoples in settler institutions is likely to make a difference: on one hand, Indigenous people may see themselves reflected in these institutions and consequently feel better represented; on the other hand, these forms of representation do not challenge the underlying colonial nature of these institutions. Using data from the 2019 and 2021 Canadian Election Studies, our statistical analysis demonstrates that: (1) diffuse support is significantly lower among Indigenous peoples than non-Indigenous peoples, including people of color; (2) Indigenous respondents across multiple peoples have similarly low levels of diffuse support, and (3) being represented by an Indigenous Member of Parliament does not change the levels of diffuse support among Indigenous peoples. Overall, our research highlights the outstanding challenges to achieving reconciliation through the Canadian state and points to ways large-N analyses may be made more robust.
Public Opinion Toward Critical Race Theory in Academia, Legislation, and Name
Authors: Giersch Jason , Liebertz Scott , Duquette Breanna , Yao-Kouame Koffi
Published: October 2024

Political wrangling over Critical Race Theory (CRT) in the United States has produced policies banning its teaching in jurisdictions across the country. However, laws touted as “anti-CRT” have little in common with the original, academic origins of the phrase. In this study, we use a Qualtrics-based survey experiment to assess how participants’ support for a ban will change depending on whether the ban reflects core tenets of academic researchers’ use of CRT, the phrase itself, or elements common to many of the laws intended to ban it. We find that these three different frames do indeed change support for such policies, and the effects are dependent upon partisanship. We interpret our results to be empirical evidence of the phrase “Critical Race Theory” complicating political discourse.
Current or recent malaria infection is associated with elevated inflammation-adjusted ferritin concentrations in pre-school children: a secondary analysis of the BRINDA database

Published: October 2024

Inflammation and infections such as malaria affect micronutrient biomarker concentrations and hence estimates of nutritional status. It is unknown whether correction for C-reactive protein (CRP) and α1-acid glycoprotein (AGP) fully captures the modification in ferritin concentrations during a malaria infection, or whether environmental and sociodemographic factors modify this association. Cross-sectional data from eight surveys in children aged 6–59 months (Cameroon, Cote d’Ivoire, Kenya, Liberia, Malawi, Nigeria and Zambia; n 6653) from the Biomarkers Reflecting Inflammation and Nutritional Determinants of Anaemia (BRINDA) project were pooled. Ferritin was adjusted using the BRINDA adjustment method, with values < 12 μg/l indicating iron deficiency. The association between current or recent malaria infection, detected by microscopy or rapid test kit, and inflammation-adjusted ferritin was estimated using pooled multivariable linear regression. Age, sex, malaria endemicity profile (defined by the Plasmodium falciparum infection prevalence) and malaria diagnostic methods were examined as effect modifiers. Unweighted pooled malaria prevalence was 26·0 % (95 % CI 25·0, 27·1) and unweighted pooled iron deficiency was 41·9 % (95 % CI 40·7, 43·1). Current or recent malaria infection was associated with a 44 % (95 % CI 39·0, 52·0; P < 0·001) increase in inflammation-adjusted ferritin after adjusting for age and study identifier. In children, ferritin increased less with malaria infection as age and malaria endemicity increased. Adjustment for malaria increased the prevalence of iron deficiency, but the effect was small. Additional information would help elucidate the underlying mechanisms of the role of endemicity and age in the association between malaria and ferritin.
Reform, Rails, and Rice: Political Railroads and Local Development in Thailand
Authors: Paik Christopher , Vechbanyongratana Jessica
Published: October 2024

How do external threats to state sovereignty benefit local development? In this paper, we look at Thailand’s railroad projects in the late-nineteenth and early-twentieth centuries as an example of a state’s strategic response to colonial encroachment. By transporting government officials and establishing a permanent administrative presence, the railways served to ensure Thailand’s sovereignty over peripheral regions and bring them under direct governance. These regions, long considered economically unviable and disconnected from Bangkok, gained rail access due to their strategic importance and, in turn, witnessed urbanization and increased agricultural production.
Internal Migration in the United States: Rates, Selection, and Destination Choice, 1850–1940
Authors: Zimran Ariell
Published: October 2024

I study native-born white men’s internal migration in the United States over all possible 10- and 20-year periods between 1850 and 1940. Inter-county migration rates—after implementing a new method to correct for errors in linkage—were stable over time. Migrant selection on the basis of occupational status was neutral or slightly negative and also largely stable. But the orientation of internal migration changed over time, declining in distance and increasingly driving urbanization. In the 1930s, migration became less common and less urban oriented. These results provide a clearer understanding of historic U.S. internal migration than previously possible.
Reinterpreting radio frequency heating and current drive theory in a tokamak
Authors: Catto Peter J.
Published: October 2024

Quasilinear treatments are widely used for tokamaks to evaluate radio frequency (rf) heating and current drive. Even though the core of a tokamak plasma is weakly collisional, the solution of the linearized kinetic equation is evaluated using unperturbed collisionless trajectories while often treating successive poloidal circuits of the passing (and trapped) particles as uncorrelated or nearly so. In addition, the most important effect of tokamak geometry, the mirror force, is usually mistreated or ignored when obtaining the solution. These concerning aspects of rf treatments are clarified by considering lower hybrid heating and current drive to illustrate that the electrons in resonance with the applied rf are enclosed by narrow collisional boundary layers, and that tokamak geometry makes it necessary to retain poloidal variation when solving a weakly collisional linearized kinetic equation. Other aspects such as collisional boundary layers at the trapped–passing boundary, cyclotron resonances, and the limitations of quasilinear theory are also considered. The new insights lead to a fundamentally different formulation and interpretation of the solution of the linearized Fokker–Planck equation used for rf quasilinear theory in a tokamak, while retaining many of the features that have contributed to its successful application to rf heating and current drive.
A New Corpus of Roman Coins from England and Wales. An Overview of the Evidence and Analysis of the Data
Authors: Henry Richard
Published: October 2024

This paper considers a new corpus of 490,154 Roman coins (site finds) which have been recorded from England and Wales. The corpus provides British and regional means to aid in the preparation of coin reports in line with Historic England guidelines, along with spatial data providing new opportunities for research. The methods of data collection will be detailed and some of the possibilities this dataset can provide presented through a number of case studies. Through the consideration of applied numismatic analyses, the social distribution of the material and, crucially, the spatial distribution of Roman coinage, we can identify new trends and patterns. Case studies evaluating the fourth century will emphasise the changing importance of settlements in Roman Britain and identify those linked with the late Roman state. Furthermore, the retraction of coinage distributions in the second half of the fourth century will be explored. Building on the national and site type means explored within the paper, the full dataset has been made available in a range of forms on the Archaeology Data Service and in an interactive map developed by Maploom.
The power of statues: constructing imperial narratives under the Ptolemies
Authors: Fischer-Bovet Christelle
Published: October 2024

This article examines how and why the Ptolemies, soon after they succeeded Alexander in Egypt, orchestrated the return of Egyptian statues supposedly stolen by the Persians, drawing on the cultural memory of different population groups: Egyptians and Graeco-Macedonians. First, it argues that the Ptolemies invested energy in searching for Egyptian objects and gods’ statues in the Levant, which they distributed among the temples, though some may have been newly fabricated statues. Second, the study aims to reconstruct what the Ptolemies knew about earlier Greek and Near Eastern traditions of seizing and returning statues, which mixed elements of truth with topoi. This reconstruction serves to explain how meaningful it was to Egyptians and Graeco-Macedonians to bring back statues after each campaign. Finally, comparing the tale of Bentresh, the account of Sarapis’ origin by Tacitus and the Ptolemaic stelae, the article suggests that these narratives highlighted Egypt as the centre of the world with the most powerful ruler, a claim appealing to all its inhabitants.
Baby talk on stage: performing Aristophanes Clouds 1382
Authors: Sluiter Ineke , Levelt Claartje C.
Published: October 2024

In a scene of father-son conflict in Aristophanes’ Clouds, father Strepsiades supports his right to be treated well by his son Pheidippides by reminding the boy of how well he was taken care of as a baby. Even before Pheidippides could talk properly, his father catered to his every wish. If he said ‘brū’, his father would get him something to drink, ‘mammā’ would make him get food, and ‘kakkā’ would lead to his being taken outside to relieve himself. These baby-words have always been taken for what Strepsiades claims they were: meaningful and intentional baby requests.

Starting with brū, we discuss ancient and modern interpretations of the passage and contextualize it within the history of ancient and later Western thought about child language. We then propose a new interpretation of brū as the conventional rendition of a universal baby vocalization, what is known as a ‘raspberry’. In performance, this would lead to a mimetic ‘depiction’ in the middle of Strepsiades’ sentence. Finally, we return to the utterances mammā and kakkā to show that there, too, Strepsiades may be demonstrating parental devotion by interpreting the virtually unintelligible and by acting out baby activities that lend plausibility to his mantic performance.
Wake flow past a submerged plate near a free surface
Authors: McLean E. , Bowles Robert , Vanden-Broeck Jean-Marc
Published: October 2024

A wake model is pursued for potential flow past a submerged, finite-length plate that is perpendicular to a uniform, horizontal stream bounded above by a free surface. The effects of gravity are included along the free surface. The approach is to adopt an open-wake model such that the wake boundaries become parallel to the undisturbed stream at some (unknown) point downstream. Boundary integral equations are formed and then discretised along the wake boundaries and free surface in order to obtain a solution numerically. In terms of the dependency of the solution on various parameters, the problem will be formulated in two ways. First, for a given Froude number and ratio of the length of the vertical plate to the draft (the depth of the bottom of the vertical plate relative to the undisturbed free surface), the effect of the wake underpressure coefficient on the size of the wake will be considered. Then, the problem will be discussed where we instead (more naturally) fix the Froude number, draft and length of the vertical, submerged plate. The dependencies of the solution on these parameters will be analysed regarding the effects on several factors, including the size of the wake, the relative lengths of the upper and lower wake boundaries, and the resulting wake underpressure coefficient.
The Past Is Not What It Used to Be: Contemporary Myths, Cold War Nostalgia and Abandoned Soviet Nuclear Bases
Authors: Kiarszys Grzegorz
Published: October 2024

This article delves into the contemporary social perception of the three abandoned Soviet Cold War tactical nuclear bases in Poland, focusing on often overlooked phenomena in archaeological studies such as the contemporary myths (folk tales, contemporary legends, modern folklore, etc.) and nostalgia that have emerged around these sites. While contemporary myths and nostalgia are distinct phenomena with different outcomes, they share a common feature: a mythologized approach to the past. Established historical and archaeological narratives, derived from detailed studies, often coexist with alternative versions of the past inspired by folk imagination. This article aims to highlight their cultural value as an integral part of local identity, actively shaping the perception of material heritage. Contemporary myths offer insight into another layer of collective perception of the past, while nostalgia delves into the emotional aspects of human existence, coping with transience and searching for meaning.
Registering Theory-Based Predictions in Political Science
Authors: Miller Andrew Cesare
Published: October 2024

How can political scientists rigorously evaluate the predictive power of theories? Many peer-reviewed political science articles include predictions about future outcomes, and scholars make predictions on social media and other public forums. The prevalence of predictions suggests that scholars recognize the utility of leveraging theories for this purpose; however, the predictions often are not made in a manner that allows for rigorously evaluating their accuracy. Building on the increasing popularity of study preregistration in the social sciences, this article proposes “prediction registration” as a means for scholars to publish falsifiable, systematic, and verifiable theory-based predictions. Increasing the rigor of predictive theory testing can advance often-circular debates about accuracy and presents a “win-win” for scholars who aim to test the predictive power of theories. With a more rigorous approach, correct predictions would better demonstrate a theory’s ability to forecast outcomes, and missed predictions would reveal information that can be used to calibrate the theory.
Digital DJing in the GCSE Classroom: Art or instrument?
Authors: Williams Jake
Published: October 2024

Between 2022 and 2023 I ran two experimental DJing workshops in a school in East London with Year 10 GCSE music students. They were experimental in the sense that I had not run workshops with this age group before and that I was sharing some experimental techniques with digital DJ technology (DDJT) that I had been exploring in my own practice. They proved to be highly engaging for the young people and highlighted significant, and sometimes unexpected, benefits of using DDJT in the classroom. The results of the workshops are analysed in the context of the 2016 addition of DJing as an ‘instrument’ for the performance component of the GCSE assessment, alongside claims that this is a ‘challenge to colonisation’. While the addition is viewed as positive, it is questioned whether viewing DJing as being equivalent to other instrumental playing captures the plurality of a practice that is distributed across sonic, social and discursive realms. Historical and conceptual precedents for viewing DJing both as an instrument and as an art are explored, and it is suggested that it could also be assessed under the GCSE Art & Design criteria.

‘Sound, Image and Motion’ (SIM) is a unique interdisciplinary programme in Brazilian higher education, blending visual arts, audiovisual and sound creation. We start with a brief historical overview of avant-garde traditions in Bahia and delve into the university’s principles and guiding plan in order to situate SIM among art courses and its available resources. We explore its flexible curriculum in detail, considering the limitations posed by a new university with scarce resources, and describe the curricular structure to analyse experiences with teaching and constructing an interdisciplinary sound creation qualification within this programme.
Do religious beliefs matter for economic values?
Authors: Davis Lewis , Rodriguez Zachary
Published: October 2024

Economic studies of religion tend to focus on religious affiliation and attendance at religious services to the exclusion of other dimensions of religion, including religious belief. We address this lacuna, using data from the World Values Survey to construct an index of religious beliefs based on whether an individual believes in God, heaven, hell, an immortal soul, and the afterlife. Following the approach in a seminal article, we compare the roles of religious beliefs and attendance in determining economic values related to cooperation, patriarchy, institutional trust, lawfulness, thrift, markets, and market fairness. Controlling for denominational, country and period fixed effects and a set of individual-level characteristics, we find that religious beliefs matter for six of these seven values, relative to five for attendance. In addition, beliefs are more important than attendance for promarket and patriarchal values and less important for thrift, market fairness, lawfulness, and institutional trust. We also consider the relationships between beliefs, attendance, and economic values for eight religious’ affiliations: Protestant, Catholic, Orthodox Christian, Muslim, Buddhist, Hindu, other religions, and non-religious. Taken together, beliefs and attendance are most important for patriarchal values, promarket attitudes, lawfulness, and institutional trust. Relative to attendance, beliefs matter most for patriarchal attitudes and least for institutional trust. Our results suggest that religious beliefs constitute an important dimension of religious life. An exclusive focus on attendance may understate the role of religion in economic values.
Fra Giovanni Angelico Da Fiesole

Published: October 2024

“It is of its very essence that the recognition of beauty should satisfy the will.”—ST.Thomas.

It is difficult to write about Fra Angelico without rhapsodizing. “He cannot be praised too much”: the beauties of his pictures “baffle description”: “his art was not only inborn and inspired but also exercised with singular care, ability and judgment.” “He perfected the mystic poetry of art.” These and suchlike phrases taken haphazard from sketches of his life, can be found in almost any book that speaks of him. One is almost tempted at the outset to shirk the effort of analysis with a Chaucerian “There is na more to say,” for at the best words are inadequate expressions of the thoughts and emotions inspired by such a painter. Yet perhaps one can be forgiven for joining in the chorus of his praise by judging him from a somewhat unusual angle.
The Classification and Stability of Psychotic-Like Experiences

Published: October 2024

Abstract: We examined psychotic-like experiences in adults. In Session 1, 404 participants completed domain measures of the Big Five and HEXACO. We identified 25 potential Psychoticism markers in Session 2, which was roughly 3 weeks later. Exploratory factor analyses (EFAs) of the Session 1 and Session 2 scales revealed six factors: the Big Five, plus Psychoticism. Eighteen scales marked the Psychoticism factor; in addition, five scales assessing negative symptoms of schizotypy defined low Extraversion. Finally, we identified a semioverlapping set of 22 potential Psychoticism markers in Session 3 ( N = 292), which was roughly 9.5 months after Session 2. EFAs of the Session 1 and Session 3 scales produced the same six factors. Sixteen scales defined Psychoticism; four scales assessing negative symptoms of schizotypy again formed a bipolar factor with Extraversion. Scores on the Psychoticism factors correlated .78 ( N = 287) across this 9.5-month interval, demonstrating a trait-like level of stability.

Geophysical methods have proven to be useful for investigating unstable slopes as they are both non‐invasive and sensitive to the spatial distribution of physical properties in the subsurface. Of particular interest are the links between electrical resistivity and near‐surface moisture content; recent work has demonstrated that it is possible to calibrate hydrological models using geophysical measurements. In this study we explore the use of in‐field electrical resistivity data for calibrating unsaturated soil retention parameters and saturated hydraulic conductivity used for modeling unsaturated fluid flow. We study a synthetic case study, and a well‐characterized site in the northeast of England and develop an approach to calibrate retention parameters for a mudstone and a sandstone formation, the former being an actively failing unit. Petrophysical relationships between electrical resistivity and moisture content (or saturation) are established for both formations. 2D hydrological models are driven by effective rainfall estimations; subsequently these models are coupled with a geophysical forward model via a Markov chain Monte Carlo approach. For the synthetic case, we show that our modeling approach is sensitive to the moisture retention parameters, while less so to saturated hydraulic conductivity. We observe the same characteristics and sensitivities for the field case, albeit with a greater data misfit. Further hydrological simulations suggest that the slope retained high moisture contents in the months preceding a rotational failure. Therefore, we propose that coupled hydrological and geophysical modeling approaches could aid in enhancing landslide monitoring, modeling, and early warning efforts.
