Authors: Li Riza C. , Ding Shanshan , Ndura Kevin , Patel Vishal , Jurkovitz Claudine
Published: September 2024

Objective:

The progression of long-term diabetes complications has led to a decreased quality of life. Our objective was to evaluate the adverse outcomes associated with diabetes based on a patient’s clinical profile by utilizing a multistate modeling approach.

Methods:

This was a retrospective study of diabetes patients seen in primary care practices from 2013 to 2017. We implemented a five-state model to examine the progression of patients transitioning from one complication to having multiple complications. Our model incorporated high dimensional covariates from multisource data to investigate the possible effects of different types of factors that are associated with the progression of diabetes.

Results:

The cohort consisted of 10,596 patients diagnosed with diabetes and no previous complications associated with the disease. Most of the patients in our study were female, White, and had type 2 diabetes. During our study period, 5928 did not develop complications, 3323 developed microvascular complications, 1313 developed macrovascular complications, and 1129 developed both micro- and macrovascular complications. From our model, we determined that patients had a 0.1334 [0.1284, .1386] rate of developing a microvascular complication compared to 0.0508 [0.0479, .0540] rate of developing a macrovascular complication. The area deprivation index score we incorporated as a proxy for socioeconomic information indicated that patients who reside in more disadvantaged areas have a higher rate of developing a complication compared to those who reside in least disadvantaged areas.

Conclusions:

Our work demonstrates how a multistate modeling framework is a comprehensive approach to analyzing the progression of long-term complications associated with diabetes.
Implicit hierarchies in the EU representation of refugees: a comparative text-analysis of the European Parliament's framing of Syrian and Ukrainian diasporas
Authors: Giancaspro Gaetano , Lucenti Flavia
Published: September 2024

The article explores the discursive representations of Syrian and Ukrainian refugees in the European Parliament (EP). The theoretical framework draws on Critical Securitisation Theory, pointing out the implicit hierarchies that affect the European Union (EU) reception policies in terms of race and gender. The main hypothesis is that a stigmatisation process based on race and gender affects the representation of refugees in the EU. Against this backdrop, the manuscript delves into how speech acts can either cast refugees as urgent threats or even facilitate the de-construction of the refugee as a threat. These are investigated through Computational Text-Analysis tools, such as Word- and Bigram-Frequency Analysis, Term Frequency-Inverse Document Frequency test and Structural Topic Modelling. On the one hand, contrary to expectations of a securitisation of Syrian refugees primarily based on race, what emerges is also a process of de-personalisation that helps justify the anti-migration stand of some members of the EP (MEPs). On the other hand, the assumption that deconstruction of the refugee as a threat would mainly occur through an emphasis on cultural proximity between Ukrainian people and the EU is challenged. Instead, our analysis shows a gender-based victimisation of Ukrainian refugees, which contributes leading to protective measures being enacted by the EU.
Hydraulic fractures of the cusp shape in a Hele-Shaw cell
Authors: Zheng Zhong
Published: September 2024

We study the dynamics of hydraulic fracturing of an elastic solid in a Hele-Shaw cell. Compared with hydraulic fractures in an infinite elastic bulk, the viscous resistance comes mainly from the drag by the two parallel plates that forms the Hele-Shaw cell rather than by the fluid–solid interface. Such a feature leads to a different nonlinear differential–integral system that describes the coupled evolution of the fracture shape and pressure field. Our theory leads to hydraulic fractures of cusp shapes in the neighbourhood of the fracture tip, which is consistent with recent experimental observations. Accordingly, there exists no pressure singularity at the location of the fracture tip, which is also fundamentally different from our previous understandings of hydraulic fracturing of elastic solids.
National Identity and Preferences for Chinese Inclusion in Mexico
Authors: Acevedo Jesse , Meseguer Covadonga , Paradés Marta
Published: September 2024

In this paper, we explore the bases of Mexican national identity construction and use an array of conceptions of nationhood to study contemporary attitudes towards foreigners’ sociopolitical rights in Mexico. Rarely is the study of national identity connected with immigration policy preferences in general, and even less so outside advanced countries. We explore the content of Mexicanness and use this content to understand public opinion preferences towards the integration of diverse groups of foreigners in Mexico. We employ 2016 survey data and a survey experiment and find the persistence of xenophobic attitudes towards the Chinese community in Mexico. We also show that civic conceptions of nationhood cannot counter contemporary anti-Chinese sentiment, in great part because the civic belonging of the Chinese was defined on racial terms. Lastly, we show that these processes of national identity construction, based on the marginalization of certain groups, are persistent and shape todays’ attitudes and preferences towards the incorporation of different groups of foreigners. It remains to be explored whether material interests associated with the recent Chinese “going out” policy may be able to counter deep-seated anti-Chinismo
Improvement to the Epoch of Reionisation power spectrum using simulations with the Central Redundant Array Mega-tile (CRAM)
Authors: Selvaraj Aishwarya , Trott Cathryn , Wayth Randall Bruce
Published: September 2024

Detection of the 21 cm signal from the Epoch of Reionisation (EoR) (

$z \sim 6 - 10$

) amidst the dominant foregrounds, which are 3–4 orders of magnitude greater than the weak cosmological signal, is a challenging task for the existing 21 cm experiments. The detection is further challenged by the large Field of View (FoV) of the instrument used for observation, as it becomes necessary to excise foregrounds present within the FoV to make a successful detection. In response to the challenges faced, in our previous work, we developed and installed a new instrument – the Central Redundant Array Mega-tile (CRAM) – and integrated it within the MWA Phase II configuration. It is a larger antenna tile configuration (

$8\times 8$

dipoles) with a smaller FoV at every frequency under consideration and has multiple sidelobes of reduced response when compared with the existing Murchison Widefield Array (MWA) tiles. In this paper, we aim to demonstrate through power spectrum simulations that using the larger tile, such as the CRAM, can reduce the impact of bright radio foregrounds near the field edge. For the pedagogical approach aimed with this work, we developed a power spectrum pipeline to estimate the cylindrically averaged power spectrum. The power spectrum is estimated for MWA-MWA baselines and CRAM-MWA baselines using analytical beams, simulated diffuse sky maps and a semi-numerical 21 cm signal. Employing a drift scanning strategy, we estimate 1D and 2D power spectra for a series of two-minute observations spanning 24 hrs using the diffuse sky maps. Our simulations predict a power reduction at the edge of the EoR wedge. The reduction in foreground power is confirmed with the Fisher analysis of the expected signal-to-noise ratio (SNR) improvement, which reports a higher SNR with the power estimations from CRAM baselines when compared with the regular MWA baselines. The reduced power obtained with the CRAM baselines is consistent with the fact that the larger tile configuration has reduced the impact of foregrounds from near the horizon.
Music, Exile, and Edward Said: An Interview with Layale Chaker
Authors: Shaheen Espinosa Andrea
Published: September 2024

The following interview with Layale Chaker, conducted on 14 September 2023, delves into her unique journey as a Palestinian-Lebanese composer, highlighting the pivotal role of music in shaping her sense of “home” following the Lebanese Civil War. Drawing from her diverse musical upbringing, spanning community choirs to formal conservatory education, Chaker elucidates the disparity between institutional training and the lived musical experiences of the Arab world, informing her quest for authenticity in composition.

Chaker recounts her involvement with the West-Eastern Divan Orchestra, founded by Daniel Barenboim and Edward Said, juxtaposed with her decision to pursue an individual artistic trajectory. Central to the conversation is her composition “En Présence de l'Absence – Homáge à Edward Saïd,” revealing a deeply personal connection to Said's legacy and a nuanced exploration of his ethos through music.

The interview culminates with insights into Chaker's forthcoming opera, “Ruinous Gods,” co-crafted with playwright Lisa Schlesinger. Addressing the profound trauma of refugee children afflicted with uppgivenhetssyndrom (resignation syndrome), the opera promises a poignant musical narrative probing themes of parenthood, displacement, and societal obligation. Set for premiere at the 2024 Spoleto Festival USA, Chaker's work continues to blend artistry with advocacy, offering a resonant reflection on human resilience and responsibility.

Disordered eating (DE) is associated with elevated cardiometabolic risk (CMR) factors, yet little is known about this association in non-Western countries. We examined the association between DE characteristics and CMR and tested the potential mediating role of BMI. This cross-sectional study included 2005 Chinese women (aged 18–50 years) from the 2015 China Health and Nutrition Survey. Loss of control, restraint, shape concern and weight concern were assessed using selected questions from the SCOFF questionnaire and the Eating Disorder Examination-Questionnaire. Eight CMR were measured by trained staff. Generalised linear models examined associations between DE characteristics with CMR accounting for dependencies between individuals in the same household. We tested whether BMI potentially mediated significant associations using structural equation modelling. Shape concern was associated with systolic blood pressure (β (95 % CI) 0·06 (0·01, 0·10)), diastolic blood pressure (DBP) (0·07 (95 % CI 0·03, 0·11)) and high-density lipoprotein (HDL)-cholesterol (–0·08 (95 % CI –0·12, −0·04)). Weight concern was associated with DBP (0·06 (95 % CI 0·02, 0·10)), triglyceride (0·06 (95 % CI 0·02, 0·10)) and HDL-cholesterol (–0·10 (95 % CI –0·14, −0·07)). Higher scores on DE characteristics were associated with higher BMI, and higher BMI was further associated with lower HDL-cholesterol and higher other CMR. In summary, we observed significant associations between shape and weight concerns with some CMR in Chinese women, and these associations were potentially partially mediated by BMI. Our findings suggest that prevention and intervention strategies focusing on addressing DE could potentially help reduce the burden of CMR in China, possibly through controlling BMI.
Exploring the impact of cover crops in integrated pest management: pest and natural enemies population dynamics in no-tillage cotton production

Published: September 2024

Conservation agriculture plays an important role in the sustainability of production systems, notably for globally significant crops such as cotton. This study explores the integration of the no-tillage system (NTS) with integrated pest management (IPM) by incorporating cover crops. The aim is to assess the impact of these living or dead covers on the management of insect populations, the indices diversity of phytophagous insects and natural enemies, and to investigate the population fluctuation of these arthropods, considering a variety of crops in the NTS before and after cotton planting. The trial, conducted over two consecutive cropping seasons in Mato Grosso do Sul State, Brazil, employed a randomised block design with four repetitions. The treatments included cover crops with the highest potential for use in the region, such as millet (Pennisetum glaucum glaucum L.), corn (Zea mays L.), brachiaria (Urochloa ruziziensis), black velvet bean (Stizolobium aterrimum), forage sorghum (Sorghum bicolor L.), and white oats (Avena sativa L.) and a mix of white oats with brachiaria. The results indicated that the black velvet bean stands out as the most effective cover crop, providing the best performance in terms of non-preference to the attack of the evaluated pest insects. Conversely, brachiaria proves to be more susceptible to infestations of Dalbulus maidis (DeLong and Wolcott) (Hemiptera: Cicadellidae), and Diabrotica speciosa (Germar, 1824) (Coleoptera: Chrysomelidae). The study underscores the relevance of the judicious choice of cover crops in IPM and in promoting agricultural biodiversity, creating a strategic tool to enhance the sustainability and efficiency of the cotton production system in the context of the NTS.
New SIMS U–Pb zircon age on the macroscopic multicellular eukaryotes from the early Mesoproterozoic Gaoyuzhuang Formation, North China
Authors: Chen Kai , Yang Chuan , Miao Lanyun , Zhao Fangchen , Zhu Maoyan
Published: September 2024

Decimetre-scale carbonaceous macrofossils from the Mesoproterozoic Gaoyuzhuang Formation in the Yanshan Range are known as the current oldest unambiguous evidence of macroscopic multicellular eukaryotes. Here, we reported a new SIMS zircon age of 1588.8 ± 6.5 Ma from a volcanic tuff in the Qianxi County of Hebei Province, about 11 m above the macrofossil’s horizon. This new age provides a direct age constraint on the macroscopic eukaryotic fossils from the Gaoyuzhuang Formation. It indicates that macroscopic life with the moderate diversity and certain morphological complexity had already evolved at the beginning of the Mesoproterozoic, and implies a possibility of discovering macroscopic eukaryotes in earlier rocks. This study also calls for a stratigraphic framework to integrate biological and environmental studies in different regions for a better understanding of the evolution of multicellular organisms and environmental change during this important period.
Mapping Women’s Memories of Britain’s Forced Resettlement Scheme in Late Colonial Kenya, c. 1953–1960
Authors: Rebisz Bethany
Published: September 2024

This article maps the memories of Gĩkũyũ women and girls who were forcibly concentrated during the 1950s emergency period in Kenya. Using Britain’s strategy of ‘villagization’, it considers the unique forms of surveillance and violence deployed against women understood as the ‘backbone’ of the anti-colonial Mau Mau movement. By analysing colonial records and women’s oral testimonies, the article examines civilian relationships to coercively designed counterinsurgency environments. It situates these ‘villages’ into a longer tradition of Britain’s carceral landscape across colonial states, offering fresh insights to established histories of violence, gender, and colonialism.

α-Lactalbumin (α-LA) and β-lactoglobulin (β-LG) are major whey proteins in bovine milk. We studied the effects of these molecules on the intestinal cell response by comparing the native form with the denatured form containing oligomers obtained by treatment with 2,2,2-trifluoroethanol (TFE). We previously reported that proteins in native and TFE-treated forms exhibited cell growth stimulation and cytotoxicity, respectively, in undifferentiated rat crypt IEC-6 and human colon Caco-2 cells. However, neither whey protein showed cytotoxicity even in the TFE-treated form in differentiated Caco-2 cells. Only undifferentiated immature intestinal cells can distinguish between these native and denatured proteins. Moreover, α-LA and β-LG exhibited different oligomer formation characteristics during the TFE treatment. In the present study, we compared the effects of native and TFE-treated whey proteins on IEC-6 cells in more detail. The native forms of both whey proteins exhibited cell proliferative effects in a concentration-dependent manner. For the TFE-treated forms, α-LA showed rapid and potent cytotoxicity, whereas β-LG altered cell responses depending on its concentration and exposure time; lower concentration/shorter exposure and higher concentration/longer exposure induced cell growth stimulation and cytotoxicity, respectively. Pre-treatment of the cell membrane with cholesterol suppressed the effects on the cell response only in TFE-treated β-LG (TFE-β-LG). In a preliminary examination using inhibitors of signal transduction, TFE-treated α-LA acted on the intrinsic apoptosis pathway via Bcl-2-associated X and p53, whereas the action of TFE-LG did not require this pathway. Tyrosine phosphorylation is necessary for the cell proliferation effect of both native whey proteins; however, native α-LA, but not native β-LG, also required activation of the pathway with selective epidermal growth factor receptor tyrosine kinase and Janus kinase 2/3. In summary, the two major bovine milk whey proteins induced similar yet discrete responses in undifferentiated intestinal cells. Even when oligomers are formed, β-LG may be much less hazardous to immature intestinal cells than α-LA.
GX: a GPU-native gyrokinetic turbulence code for tokamak and stellarator design

Published: September 2024

GX is a code designed to solve the nonlinear gyrokinetic system for low-frequency turbulence in magnetized plasmas, particularly tokamaks and stellarators. In GX, our primary motivation and target is a fast gyrokinetic solver that can be used for fusion reactor design and optimization along with wide-ranging physics exploration. This has led to several code and algorithm design decisions, specifically chosen to prioritize time to solution. First, we have used a discretization algorithm that is pseudospectral in the entire phase space, including a Laguerre–Hermite pseudospectral formulation of velocity space, which allows for smooth interpolation between coarse gyrofluid-like resolutions and finer conventional gyrokinetic resolutions and efficient evaluation of a model collision operator. Additionally, we have built GX to natively target graphics processors (GPUs), which are among the fastest computational platforms available today. Finally, we have taken advantage of the reactor-relevant limit of small

$\rho _*$

by using the radially local flux-tube approach. In this paper we present details about the gyrokinetic system and the numerical algorithms used in GX to solve the system. We then present several numerical benchmarks against established gyrokinetic codes in both tokamak and stellarator magnetic geometries to verify that GX correctly simulates gyrokinetic turbulence in the small

$\rho _*$

limit. Moreover, we show that the convergence properties of the Laguerre–Hermite spectral velocity formulation are quite favourable for nonlinear problems of interest. Coupled with GPU acceleration, which we also investigate with scaling studies, this enables GX to be able to produce useful turbulence simulations in minutes on one (or a few) GPUs and higher fidelity results in a few hours using several GPUs. GX is open-source software that is ready for fusion reactor design studies.
Optimisation of gyrokinetic microstability using adjoint methods
Authors: Acton G.O. , Barnes M. , Newton S. , Thienpondt H.
Published: September 2024

Microinstabilities drive turbulent fluctuations in inhomogeneous, magnetised plasmas. In the context of magnetic confinement fusion devices, this leads to an enhanced transport of particles, momentum and energy, thereby degrading confinement. In this work, we describe an application of the adjoint method to efficiently determine variations of gyrokinetic linear growth rates on a general set of external parameters in the local

$\delta f$

-gyrokinetic model. We then offer numerical verification of this approach. When coupled with gradient-based techniques, this methodology can facilitate the optimisation process for the microstability of the confined plasmas across a high-dimensional parameter space. We present a numerical demonstration wherein the ion-temperature-gradient instability growth rate in a tokamak plasma is minimised with respect to flux surface shaping parameters. The adjoint method approach demonstrates a significant computational speed-up compared with a finite-difference gradient calculation.
Description and circadian rhythms of Chandlerella sinensis Li, 1933 (Nematoda; Onchocercidae), with remarks of microfilariae effects on the host health

Published: September 2024

During investigation of common linnet (Linaria cannabina) blood using the buffy coat method one bird with microfilariae in the blood was found. The morphometric description of adult worms corresponded to the Chandlerella sinensis. This species was found for the first time in common linnets. DNA sequences of cox1 and 28S gene fragments of adult worm recovered during necropsy was identical to that from the microfilariae in the bird blood. Phylogenetic analysis of the cox1 gene fragment clustered this parasite with Chandlerella quiscali. Histological examination revealed the presence of microfilariae in the lumen of small capillaries and other blood vessels in different organs, but no inflammations were notice. The greatest number of microfilariae was in the lungs. Even if there was no inflammation, but vessels associated with the lungs were markedly distended with blood, parabronchial walls were thickened and, in some cases, almost completely obstructing the lumen. The large number of microfilariae in lungs indicates possible disturbance of gas exchange in the lungs adversely affected the ability of the bird to exercise and made breathing difficult at rest. The investigation of circadian rhythm of the microfilariae showed that C. sinensis microfilariae in blood of common linnet were more numerous at night and morning and less numerous at midday. The survival rate of mosquitoes infected with C. sinensis microfilariae was significantly lower than that of uninfected mosquitoes.
Meta-learning as a bridge between neural networks and symbolic Bayesian models

Published: September 2024

Meta-learning is even more broadly relevant to the study of inductive biases than Binz et al. suggest: Its implications go beyond the extensions to rational analysis that they discuss. One noteworthy example is that meta-learning can act as a bridge between the vector representations of neural networks and the symbolic hypothesis spaces used in many Bayesian models.

Binz et al. highlight the potential of meta-learning to greatly enhance the flexibility of AI algorithms, as well as to approximate human behavior more accurately than traditional learning methods. We wish to emphasize a basic problem that lies underneath these two objectives, and in turn suggest another perspective of the required notion of “meta” in meta-learning: knowing what to learn.
A database of ambiguous Chinese characters with measures for meaning dominance and meaning balance
Authors: Chen Huilin , Xu Xu , Li Haiquan , Yu Xinyue , Pan Ruting , Zhang Zhaoyang
Published: September 2024

Chinese characters hold great potential to help inform and enrich psycholinguistic research on lexical ambiguity as a large portion of them are ambiguous in nature with meaning varying from context to context. This report presents a psycholinguistic database that contains over 2000 characters with normative measures for meaning dominance and meaning balance, that is, the relative frequency of each meaning associated with a target character and the degree of balance across the meanings of the character. The measurement process takes advantage of the fact that, in Chinese, generating words containing a target character is the most convenient way to specify and disambiguate character meanings. Character meanings stored in ordinary people’s mental lexicon are identified based on the words, along with a small portion of meaning descriptions, listed by over 900 native speakers. The measures of meaning dominance and meaning balance for the characters are derived from computing the relative frequencies of the meanings. Potential research and practical applications of the database, as a valuable tool, to enhance our understanding of the acquisition, representation, and processing of ambiguous lexical items are discussed.
Pragmatic competence and pragmatic tolerance in foreign language acquisition—revisiting the case of scalar implicatures
Authors: Schulz Johannes , Wonnacott Elizabeth
Published: September 2024

Previous L2 studies used binary Truth-Value-Judgment (TVJ) tasks to investigate L1–L2 differences in scalar implicature derivation (some X implicates some but not all X). They examined participants’ judgments of sentences with weak scalar expressions (“Timothy ate some of the pretzels”) when stronger ones are true (“Timothy ate all of the pretzels”). Some studies indicate adult L2 learners are less likely than L1 users to accept such statements while others found the opposite, concluding that implicature derivation is “costly” for L2 learners, rendering them less pragmatically competent than L1 users. Importantly, related L1 research suggests that TVJ tasks only capture sensitivity to under-informativeness. This sensitivity might be completely overridden by metalinguistic attitudes in binary tasks, whereas graded tasks reveal nuanced judgment patterns. Exploring L2 response behaviors, we tested English L1 speakers and competent German L2 English learners using binary and graded tasks. In both tasks, we found evidence of pragmatic responding with no evidence of differences between groups. Bayes factor analyses of the graded data favored H0 over the hypotheses that L2 learners provide fewer or more rejections to under-informative input than L1 learners. We explore implications for L2 learners’ pragmatic abilities, differences with previous studies, and the role of TVJ tasks in under-informative contexts.
Instrumented bio-inspired cable-driven compliant continuum robot: static modeling and experimental evaluation

Published: September 2024

Energy efficiency is inherent for autonomous robotic device. Snakes are well known for their ability to low energy consumption when swimming. However, the swimming know-how is poorly understood. Designing a snake robot inspired by snakes as a tool to find out the swimming energy efficiency crucial point will lead to the development of hyper efficient undulating locomotors. In this article, we introduce a four tendons driven continuum robot made of bio-inspired compliant vertebrae to assess the energy consumption of a planar and a spatial snake motion. The tendon-driven continuum robot constitutes the head–neck part of a locomotor snake robot. A static modeling coupled with an optimization method was implemented to generate bio-inspired motions recorded on snake swimming head. A friction model describing the friction between cables and the disks is investigated and compared to a frictionless model. The proposed prototype is equipped with exteroceptive sensors to record motion and proprioceptive sensors to measure cable forces applied at the tip of the robot. Hence, the work of the forces, thus the energy required to execute a trajectory are computed and analyzed. The energy is introduced as a key criterion to assess the swimming motion of a locomotor snake robot.
A model of endogenous education quality: the role of teachers
Authors: Rodrigues Mauro , Souza Danilo
Published: September 2024

Over the last 40 years, the massive increase in average years of schooling in developing countries was not accompanied by a similar increase in Gross Domestic Product (GDP) per capita. We investigate this apparent disconnect between education and growth by focusing on the role of education quality. We propose an overlapping generations model which features an endogenous tradeoff between quantity and quality of education. A policy that increases average years of schooling then has an ambiguous effect on long-run human capital and GDP per capita. We also consider a quantitative version of the model to understand the Latin American experience between 1970 and 2010.
Optimal fiscal policy in small open economies with habit persistence
Authors: Jung Yongseung
Published: September 2024

This paper sets up a small open economy model with habit persistence in consumption in which distortionary taxation is available in a flexible price environment. In open economy, the habit persistence in consumption aggravates the terms of trade externality, absent in closed economy, calling for more aggressive fiscal policy. While optimal labor income taxes are time-invariant in a closed economy with internal habit, they should be time-varying in an open economy to alleviate the terms of trade externality, even if the intertemporal elasticity of substitution equals the intratemporal elasticity of substitution. In a small open economy composed of households with habit persistence in consumption, households’ decision to gradually adjust their consumption and labor hours intensifies the undesirable terms of trade externality or the terms of trade channel. This generates a time-varying wedge between the efficiency conditions of the Ramsey planner and the market equilibrium conditions, calling for a time-varying taxation which takes into account the intertemporal elasticity of substitution and the intratemporal elasticity of substitution between home and foreign goods, in addition to the degree of habit and goods market distortion. The volatility of optimal tax rate increases with the degree of habit, whether households have external or internal habit. The volatility of tax rate shows an inverted U-shape in the degree of openness in the small open economy with habit. Finally, the optimal labor income tax rate moves countercyclically for low degree of intratemporal elasticity of substitution, while it moves procyclically for high degree of intratemporal elasticity of substitution.
Optimal taxes and basic income during an episode of automation: a worker’s perspective
Authors: Atolia Manoj , Holland Morgan , Kreamer Jonathan
Published: September 2024

Motivated by distributional concerns raised by recent breakthroughs in AI and robotics, we ask how workers would prefer to manage an episode of automation in a task-based model, which distinguishes between automation and traditional technical progress. We show that under majority voting with the option to implement a “partial” UBI (as transfers to workers) it is optimal to tax capital at a higher rate than labor in the long run to fund the partial UBI. We show that, unlike traditional technical progress, automation always lowers the labor share in the long run, justifying distributional concerns. A quantitative analysis of an episode of automation for the US economy shows that it is optimal from the workers’ perspective to lower capital taxes and transfers over the transition. Nevertheless, this policy increases worker welfare by only 0.7% in consumption-equivalent terms, compared with a 21.6% welfare gain to entrepreneurs, because the welfare gains to workers from lower capital taxes are second-order, while the gains to entrepreneurs are first-order.
The municipal government channel of monetary policy
Authors: Wilson Matthew
Published: September 2024

Monetary policy in the USA affects borrowing costs for state and local governments, incentivizing municipal borrowing and spending, which in turn affects economic outcomes. Using municipal bond indices and transaction-level data, I find that responses to monetary policy are dampened relative to treasuries and heterogeneous across location and bond characteristics. In my baseline estimate, muni yields move 26 bp after a 100 bp monetary shock. To study implications for local fiscal policy, I model US localities as small open economies in a monetary union with independent fiscal agents. In a calibrated model, monetary transmission is significantly affected by municipal borrowing costs.
Diet culture on TikTok: a descriptive content analysis
Authors: Munro Emily , Wells Gabriella , Paciente Rigel , Wickens Nicole , Ta Daniel , Mandzufas Joelie , Lombardi Karen , Woolard Alix
Published: September 2024

Objective:

To investigate how dieting is portrayed on TikTok and the potential implications for public health considering the effect of diet culture on eating disorders amongst young people.

Design:

A cross-sectional descriptive content analysis of 250 videos from the five most popular diet-related hashtags. A codebook was developed to analyse the content of the videos and collect the engagement for each video (likes, comments and shares).

Setting:

TikTok website.

Participants:

There were no participants in this study.

Results:

More than half of the videos portrayed ‘body checking’, a potentially harmful practice for body image. Of the videos that represented body image, almost half represented body image negatively. However, most videos promoted the idea of ‘healthy eating’, and only 6·4 % displayed disordered eating behaviours. Over half of the videos provided dietary advice, and of those videos, most content creators claimed to be experts (64 %). Claiming expertise was not significantly associated with engagement; however, the use of humour was significantly associated with engagement. Additionally, males were more likely than females to disclose their goals of the diet.

Conclusions:

Overall, it appears that TikTok is commonly used to share nutrition tips and personal experiences around dieting and eating in general, often employing humour as an effective technique. The popularity of the platform and rapid dissemination of information would be a useful tool for health professionals, especially those working with eating disorders, to utilise.
The Manuscript Source of Philippe II d'Orléans's Cantates françaises: A New Light on Early Eighteenth-Century Transnational Networks of Connoisseurship and Collecting
Authors: Fader Don
Published: September 2024

The rediscovery of a unicum manuscript source of cantates françaises by Philippe II d'Orléans in the Württembergische Landesbibliothek, Stuttgart, provokes a re-evaluation of not only the provenance of the collection to which it belongs, but also the role played by diplomacy, sociability and cultural exchange in the history of the cantate française. The manuscript's contents all reflect Philippe's use of international connections to acquire music and engage musicians in the period 1701–1706. The manuscript forms part of a corpus of French scores that belonged to Marie-Thérèse de Lannoy de La Motterie, an aristocratic amateur harpsichordist with an interest in both French and Italian music, and in cantates. As wife of Joseph Lothar von Königsegg und Rothenfels, representative of the Austrian emperor to Philippe, then regent of France, she was engaged in the cultural life of Paris during the period 1717–1719, not only acquiring cantate prints but also a copy of Philippe's own works in the genre. Her collection reflects both her personal interests and her diplomatic cultivation of the social circles around Philippe in which music connoisseurship was an important skill. The manuscript thus highlights the important role played in the international transmission of cantates françaises by diplomatic and familial connections of noble amateurs, especially those curious about musical developments beyond their own regional practices.

Use of diverse germplasm for generating heterotic hybrids is the foremost requirement in maize. The present study was conducted by using a diverse set of inbred lines and the line × tester method was applied to identify best performing lines and to group QPM inbred lines into different heterotic groups. The test crosses, developed by following line (66) × tester (CML 161 and CML 165) mating design, were evaluated during winter 2013, rainy 2014 and 2015 seasons at Begusarai and Ludhiana, respectively. Based on the specific combining ability, the lines were categorized into two heterotic groups. Out of 66 novel inbreds, 18 lines with significant SCA with CML165 were classified in group A, 16 inbreds with significant SCA with CML161 were classified in group B and 20 inbreds with significant GCA were classified in group (AB). Nine inbred lines were selected based on their positive GCA values and pedigree crosses were developed in rainy season in 2017. Three crosses were made in heterotic group A and four crosses were in group B for synthesizing new inbred lines by using pedigree method. Heterotic grouping based inbred evaluation trial and biochemical analysis were carried out to estimate per se yield potential of developed lines and to estimate tryptophan content. QIL-4-2491 (Group-A) and QIL-4-2401 (Group-B) were the top yielders. A total of 25 crosses were made among the heterotic groups (A and B) by using 22 lines from groups A and B and three best performing hybrids were identified.

Eggplant (Solanum melongena L.) is a widely cultivated vegetable in India with enormous variability. Recent molecular techniques revealed three closely related but distinct Solanum species (S. melongena, S. incanum and S. insanum), with the Indian subcontinent being a domesticated centre. Spontaneous hybridization between S. insanum and S. melongena has led to the formation of naturally introgressed lines and limited studies are available to differentiate these genotypes using morphological key traits. Current study aimed to delineate naturally introgressed genotypes of Indian eggplant collections using morphological key traits for plant genetic resources (PGR) management and assess available genetic diversity. The study characterized a collection of 157 eggplant germplasm at ICAR-NBPGR, Regional Station, Kerala, and identified 30 naturally introgressed, 10 wild progenitors and 117 cultivated eggplants. The key morphological traits are prickliness (stem, petiole, calyx and pedicle), leaf base shape, fruit shape and size. Other fruit traits such as length, breadth and mesocarp texture could also provide some clues for delineating introgressed genotypes from S. insanum and S. melongena. Basic statistical analysis of six quantitative traits of 157 eggplant genotypes revealed the presence of considerable amount of variation (CV%) in which fruit length/breadth ratio showed higher variation (73.87) followed by fruit length (54.73) and average fruit weight (53.5). The frequency distribution of 14 qualitative traits revealed the presence of all character states among them. Key traits identified under study could provide clues to identify individual plants at field level to plant taxonomist/explorers and also to aid gene bank curators for PGR management.

Early morning flowering (EMF) is a desirable trait in rice to avoid heat stress as temperatures in early morning hours are low compared to afternoon and flowering is the most sensitive stage to heat exposure. Cultivated rice accessions including both Oryza glaberrima and O. sativa were phenotyped for an EMF trait in 2016–2018 in two locations viz. Cotonou in Benin Republic and Ibadan in Nigeria. The initial screening was done in Cotonou in three phases in 2016 dry season, 2017 wet season and 2017 dry season, respectively. The 2093 accessions used in initial screening were subdivided into three groups based on flowering duration ensuring that each accession was grown under conditions which were best suited to their flowering duration. Further screening was done in Ibadan in 2018 dry season and 2018 wet season. Out of 2093 accessions taken in the initial screening only 1754 accessions germinated out of which only 64 accessions exhibited EMF phenotype consistently across the cultivated years, seasons and locations. Among the 64 accessions exhibiting EMF phenotype, 15 accessions also showed an early peak in spikelet opening time (EPSOT) trait, more than 80% flowering before 09:00 h. We conclude that 15 O. glaberrima accessions identified possessing both the EMF and EPSOT traits are suitable donors for use in breeding for heat escape in rice.
Anti-Trans Attacks: Interrogating “Gender” in Politics and Gender Scholarship
Authors: Murib Zein
Published: September 2024

This essay considers the rapid uptick in anti-trans legislation that targets transgender girls and women as an occasion to critically interrogate the ways that gender is conceptualized and operationalized in political science (Murib 2022). I argue that the disciplinary tendency to view gender as a single-axis facet of identity that is static and rooted in biology needs to be reconsidered in light of two problems. First, collapsing biological sex and gender naturalizes the gender of non-trans women and men as static, normal, and self-evident; transgender people, in contrast, are locked into perpetual processes of gendering themselves against this biological baseline (Enke 2012). Second, and as a result of this limited view of gender, political scientists face difficulties anticipating, understanding, and addressing recent mobilizations invested in maintaining White, heterosexual, and reproductive families as the cornerstone of what it means to be a proper citizen (Alexander 1994).

Over the last few years, during the pandemic, the Brazilian population has suffered several problems, ranging from health to socioeconomic impacts. When we consider Brazilian science, there has been an undeniable scientific delay generated by the pandemic, especially in areas that are not related to the coronavirus. In this context, with the aim of fostering collaboration among researchers in the field of Developmental Origins of Health and Diseases (DOHaD) and enhancing the potential for implementing public health strategies to prevent noncommunicable chronic diseases, the Brazilian Association of Developmental Origins of Health and Diseases (DOHaD Brazil) was established in 2020. In this narrative, we explore the effects of the COVID-19 pandemic in Brazil, focusing on its impacts on scientific research conducted in universities. Additionally, we underscore the significance of the DOHaD Brazil Association, particularly from the perspective of young researchers engaged in DOHaD research in Brazil.

Abstract: This longitudinal study examines long-term associations between the use of sexually explicit internet material (SEIM) during adolescence and engagement in unwanted sexual behaviors in emerging adulthood. Drawing on a four-wave panel study among 377 participants (aged 18–24, 44.3% male), using logistic regression analysis, we found that SEIM use during adolescence predicted a higher odds of having sexually touched a stranger and of having insisted on sex with someone who had refused by emerging adulthood, 5 years later. That said, the proportion of participants committing these unwanted sexual behaviors is relatively small. Respectively 10.3%, 8.5%, and 1.1% of emerging adults had sexually touched a stranger, insisted on sex with a partner who had refused, or had used force to try to have sex.
Magnetosheath High‐Speed Jet Drives Multiple Auroral Arcs Near Local Noon

Magnetosheath High‐Speed Jets (HSJs) are transient disturbances characterized by increased dynamic pressure. They can cause various geoeffects, including ultra‐low‐frequency (ULF) waves and auroras. Theoretically, when ULF waves propagate into the ionosphere as Alfvén waves, they can accelerate electrons and generate discrete auroras. However, what types of aurora can be driven by HSJs and what are the underlying mechanisms remain unknown. Using coordinated magnetosheath in situ and ground observations, here, we showed that when a HSJ was identified in the magnetosheath, multiple auroral arcs parallel to the auroral oval were observed near local noon. The electron energy spectrogram of these arcs exhibited “inverted‐V” structures, indicating the existence of quasi‐static parallel electric fields. Concurrently, long‐period ULF signals were detected on the ground, suggesting the arrival of Alfvén waves. These observations are represented by a kinetic simulation using realistic observational inputs, showing consistency with the theory regarding the generation of the “inverted‐V” structure by long‐period Alfvén waves. This study builds a previously unestablished connection among HSJ, ULF wave, and aurora, and provides a mechanism for generation of discrete auroral arcs near local noon, which may reveal the underlying mechanism behind a specific auroral activity commonly observed near local noon as shown in the paper.
