Abstract
The coronavirus pandemic posed a major challenge to mental health. Existing evidence shows that COVID-19 is related to poor emotional well-being, particularly among women. However, most work on the subject uses single-country samples, limiting the ability to generalize the disparity or explain it as a function of societal variables. The present study investigates the expression of positive and negative emotions during the pandemic as a function of gender and across 24 countries (N = 49,637). Strong gender differences emerged across countries, with women reporting more negative emotions (anxious, depressed, nervous, exhausted) and less positive emotions (calm, content, relaxed, energetic) than men. The gender gap in positive emotions was significantly wider in countries higher in individualism and narrower in countries higher in power distance. For instance, differences in emotions were larger in Western countries high in individualism, such as the USA, the UK, Italy, and France, and smaller in countries with higher collectivism and power distance, such as China, Malaysia, and South Korea, with a few exceptions like Japan and Brazil. These gender differences across countries were not explained by country-level gender inequalities indicators (GGGI and GII). Interestingly, the national severity of the pandemic, an epidemiological factor, reduced gender differences in positive emotions. These results underscore the importance of considering cultural and national factors when assessing gender differences in well-being.
Highlights on gastroesophageal tumors: the comeback of FLOT
Authors: Ilhan-Mutlu Aysegul 
Published: January 2025

Summary
This article aims to summarize the highlights of the two largest global congresses of 2024 with respect to gastroesophageal tumors. The triplet chemotherapy combination known as FLOT (5-fluorouracil, leucovorin, oxaliplatin, docetaxel), used as perioperative chemotherapy, was demonstrated to improve overall and disease-free survival in resectable gastroesophageal cancer patients some time ago. Despite being standard for this patient population, many questions for different scenarios remain open: Is FLOT also efficacious in patients with esophageal or gastroesophageal junction adenocarcinoma when compared to neoadjuvant chemoradiotherapy? Is FLOT a feasible chemotherapy option for oligometastatic patients, thereby contributing to the overall survival as “neoadjuvant” treatment before palliative resection? Can the efficacy of FLOT be strengthened by applying additional radiation treatment to patients with gastroesophageal adenocarcinoma? Is FLOT really necessary in the adjuvant setting for all patients, or can the adjuvant treatment be guided based on pathological response rates? These questions were answered to some extent in the ESOPEC and RENAISSANCE trials at the American Society of Clinical Oncology (ASCO) meeting and the TOPGEAR and SPACE-FLOT trials at European Society for Medical Oncology (ESMO) meeting. Many other FLOT-related studies for resectable as well as metastatic gastroesophageal cancer patients are yet to come.
Managing courts in competitive authoritarian regimes
Authors: Hanelt Etienne , Vincze Attila 
Published: January 2025

Abstract
More than a decade of democratic backsliding has turned Hungary into a competitive authoritarian state. The government has initiated many judicial reforms to exert control over the judiciary, yet needed to maintain plausible deniability due to formal international and constitutional standards of judicial independence. Based on interviews with Hungarian judges and experts for the judicial system, we explore techniques of managing the courts. In particular we study mechanisms of co-optation and soft repression and explain why the resistance of judges was weak. We find that a complex web of informal patronal politics undermines judicial independence in practice. Moreover, the regime fosters competition between three clients who are entrusted to manage and control the judiciary: the heads of the Supreme Court (Kúria), the National Judicial Office, and the Constitutional Court. Their resources and power ebb and flow with their reliability and performance. We conclude that competitive authoritarian regimes can maintain formally independent judicial institutions by delegating and incentivizing control over the judiciary. They thereby escape measurement, maintain plausible deniability, and evade international pressure.
Numerical analysis on heat transfer enhancement of Al2O3 and CuO-water nanofluids in annular curved tubes
Authors: Abdelmagied Mahmoud 
Published: January 2025

Abstract
The present investigation presents numerically the thermo-hydraulic performance of annular curved tubes in the turbulent flow region. The three-dimensional (3D) computational fluid dynamic (CFD) model was developed by using a commercial ANSYS 14.5 package to get additional insights on the thermo-hydraulic performance on a level of detail that is not always available in experiment results. The turbulent k-ε realize model was employed to examine the effect of Al2O3-water and CuO-water nanofluids on the heat transfer and fluid flow characteristics at different key design parameters. Three coil geometry shapes (including helical, spiral, and conical), five annular cross-section shapes (including circular, elliptical, square, rectangular, and triangular), and three cross-section areas were also investigated in this study. The numerical simulations were carried out at Reynolds numbers of 4700 to 26,700 and nanofluid volume concentrations, φ of 1%, 3%, and 5%, with constant wall temperature (CWT) heat transfer boundary conditions. The result showed that the addition of Al2O3 (45 nm) and CuO (29 nm) nanoparticles to water improves the heat transfer coefficient by 48.8%, 25.7%, and 8.4% and 37.1%, 20%, and 8.7%, respectively, at φ of 5%, 3%, and 1%, while the penalty of pressure drop is approximately negligible. The heat transfer rate per unit pumping power for helical design achieved 21.6% and 5.34% higher than conical and spiral designs, respectively, for the same curvature ratio, cross-section area, and coil length. Also, the circular shape achieved a higher heat transfer enhancement than elliptical, square, rectangular, and triangular shapes by 4%, 14.6%, 17.8%, and 30.1%, respectively. The maximum thermo-hydraulic performance index reached 1.68 and 1.58 for both Al2O3-water and CuO-water nanofluids, respectively, at φ of 5%.
From Collusion to Autonomy: Patterns of Hybrid Repression and Human Rights Activism
Authors: Meier Larissa , Peña Alejandro M. , Nah Alice M. 
Published: January 2025

Abstract
This article elaborates the notion of hybrid repression, understanding by this modalities of dissidence suppression that involve state and non-state actors interacting in various ways, from fully autonomous to close cooperation. It does so by proposing a framework to scrutinize repressive configurations on the basis of three analytical dimensions – the perpetrator of repression, the tactics used and the threats perpetrators respond to – and using this framework to perform a systematic qualitative analysis of 160 in-depth interviews with human rights activists in four different countries (Colombia, Egypt, Mexico and Kenya). On this basis, the article analytically distinguishes and empirically elaborates four different patterns of hybrid repression, namely: state rogue, corporate, communitarian and non-state armed repression. Our argument challenges the state-centric approach to political repression that still dominates much of the literature on contentious politics and comparative regime analysis, and it invites further research on how hybrid forms of repression manifest and operate in different types of social and political contexts, and in relation to different areas of activism.
Gender and Singing in Pahlavi Soundscape: Modern Feminine Culture and Masculine Politics in the Age of Popular Culture, Vision, and Rumors; A Discussion of Sensory History in Modern Iran
Authors: Nekouei Pouya 
Published: January 2025

Abstract
Focusing on the cultural history of vocal music in Pahlavi Iran, this article examines the senses in modern Iranian history. As the article shows, the performance of Iranian vocal music became subject to a gendered male and female dichotomy. While this dichotomy did not exist in early Pahlavi Iran, in the early 1950s, a gendered consciousness and language emerged among male musicophilias, eventually separating genres of vocal performance across gender lines. Hence, vocal music known as āvāz became increasingly associated with male performers, while tarāneh and tasnif were increasingly associated with female performers. As the article attempts to show, this gender dichotomy should be contextualized in the broader tension between the sense of vision and sight and disciplined notions of aurality and the body. While the “modern woman's” body permeated the visual domain in the public sphere, the cultural ideals of disciplined aurality and body docility informed the male musicophilias countercultural claims in Pahlavi Iran. Eventually, the latter attempted to challenge the female agency in the public music sphere.
The Rationality of Emotions Across Time
Authors: Moller Dan 
Published: January 2025

Abstract
Philosophers have struggled to explain the mismatch of emotions and their objects across time, as when we stop grieving or feeling angry despite the persistence of the underlying cause. I argue for a sceptical approach that says that these emotional changes often lack rational fit. The key observation is that our emotions must periodically reset for purely functional reasons that have nothing to do with fit. I compare this account to David Hume’s sceptical approach in matters of belief, and conclude that resistance to it rests on a confusion similar to one that he identifies.
Trauma exposure, contextual stressors, and PTSD symptoms: patterns in racially and ethnically diverse, low-income postpartum women
Authors: Kofman Yasmin B. , Brown Joni , Dunkel Schetter Christine , Sumner Jennifer A. 
Published: January 2025

AbstractBackgroundRacial, ethnic, and socioeconomic disparities persist in posttraumatic stress disorder (PTSD), which are partly attributed to minoritized women being trauma-exposed, while also contending with harmful contextual stressors. However, few have used analytic strategies that capture the interplay of these experiences and their relation to PTSD. The current study used a person-centered statistical approach to examine heterogeneity in trauma and contextual stress exposure, and their associations with PTSD and underlying symptom dimensions, in a diverse sample of low-income postpartum women.MethodsUsing a community-based sample of Black, Hispanic/Latina, and White postpartum women recruited from five U.S. regions (n = 1577), a latent class analysis generated profiles of past-year exposure to traumatic events and contextual stress at one month postpartum. Regression analyses then examined associations between class membership and PTSD symptom severity at six months postpartum as a function of race/ethnicity.ResultsA four-class solution best fit the data, yielding High Contextual Stress, Injury/Illness, Violence Exposure, and Low Trauma/Contextual Stress classes. Compared to the Low Trauma/Contextual Stress class, membership in any of the other classes was associated with greater symptom severity across nearly all PTSD symptom dimensions (all ps < 0.05). Additionally, constellations of exposures were differentially linked to total PTSD symptom severity, reexperiencing, and numbing PTSD symptoms across racial/ethnic groups (ps < 0.05).ConclusionsA person-centered approach to trauma and contextual stress exposure can capture heterogeneity of experiences in diverse, low-income women. Moreover, racially/ethnically patterned links between traumatic or stressful exposures and PTSD symptom dimensions have implications for screening and intervention in the perinatal period.
All that glitters is not gold: The false-symbol problem in archaeology
Authors: Tennie Claudio , Planer Ronald J. 
Published: January 2025

Abstract
Stibbard-Hawkes forcefully alerts us to the pitfall of false-negative reasoning in symbolic archaeology. We highlight the twin problem of false-positive reasoning in what we call the “false-symbol problem.” False symbols are intuitively special entities that, owing to their non-utilitarian nature, invite symbolic interpretation. But they are not symbolic. We link the false-symbol problem to work in comparative primate cognition, taking “primate art” as our main example.
Material culture both reflects and causes human cognitive evolution
Authors: Di Paolo Laura Desirèe , White Ben , Guénin–Carlut Avel , Constant Axel , Clark Andy 
Published: January 2025

Abstract
Our commentary suggests that different materialities (fragile, enduring, and mixed) may influence cognitive evolution. Building on Stibbard-Hawkes, we propose that predictive brains minimise errors and seek information, actively structuring environments for epistemic benefits. This perspective complements Stibbard-Hawkes' view.
Behavioural modernity is dead: Long live behavioural modernity
Authors: Blessing Matthias A. 
Published: January 2025

Abstract
Using Neanderthal symbolism, I extend on Stibbard-Hawkes to show that reconsidering the link between cognitive capacity and material culture extends beyond matters of preservation. A reconceptualization of behavioural modernity inclusive of both extant and extinct populations must begin with an honest theoretical separation of biological and behavioural modernity, which requires to critically engage with how we frame the underlying questions.
Don't ignore cognitive evolution during the three million years that preceded the archaeological record of material culture!
Authors: Falk Dean 
Published: January 2025

Abstract
The target article rightly questions whether the archaeological record is useful for identifying sea changes in hominin cognitive abilities. This commentary suggests an alternative approach of synthesizing findings from primatology, evolutionary developmental biology, and paleoanthropology to formulate hypotheses about cognitive evolution in hominins that lived during the three million years that preceded the record of material culture (the Botanic Age).
Sports, team games, and physical skill competitions as an important source of symbolic material culture with low preservation probability
Authors: Gallup Andrew C. , Eldakar Omar Tonsi 
Published: January 2025

Abstract
Sports, team games, and physical skill competitions appear to be a human universal and may have been prevalent throughout the hominin lineage. These activities are cognitively complex and can be associated with a distinctive and symbolic material culture. Yet, many of the artifacts used by foraging groups for sports, team games, and athletic competitions often have a low preservation probability.
The Mbuti people still reproduce a 75,000 years old recursive pattern
Authors: Barceló-Coblijn Lluís 
Published: January 2025

Abstract
Modern humans don't always leave cultural or technological evidence. Yet, Mbuti artifacts, like net-hunting tools and patterns, reveal their modern cognitive capacity. They create geometric and musical structures requiring specific working memory seen in modern Homo sapiens. Evidence from Blombos Cave suggests these skills existed 75,000 years ago, underscoring shared cognitive abilities among all modern human populations.
Advance care planning readiness, barriers, and facilitators among seriously ill Black older adults and their surrogates: A mixed methods study

Published: January 2025

Abstract

Objectives
Advance care planning (ACP) supports communication and medical decision-making and is best conceptualized as part of the care planning continuum. Black older adults have lower ACP engagement and poorer quality of care in serious illness. Surrogates are essential to effective ACP but are rarely integrated in care planning. Our objective was to describe readiness, barriers, and facilitators of ACP among seriously ill Black older adults and their surrogates.

Methods
We used an explanatory sequential mixed methods study design. The setting was 2 ambulatory specialty clinics of an academic medical center and 1 community church in Northern California, USA. Participants included older adults and surrogates. Older adults were aged 60+, self-identified as Black, and had received care at 1 of the 2 clinics or were a member of the church congregation. Surrogates were aged 18+ and could potentially make medical decisions for the older adult. The validated ACP engagement survey was used to assess confidence and readiness for ACP. What “matters most” and barriers and facilitators to ACP employed questions from established ACP materials and trials. Semi-structured interviews were conducted after surveys to further explain survey results.

Results
Older adults (N = 30) and surrogates (N = 12) were confident that they could engage in ACP (4.1 and 4.7 out of 5), but many were not ready for these conversations (3.1 and 3.9 out of 5). A framework with 4 themes – illness experience, social connections, interaction with health providers, burden – supports identification of barriers and facilitators to ACP engagement.

Significance of results
We identified barriers and facilitators and present a framework to support ACP engagement. Future research can assess the impact of this framework on communication and decision-making.
Effectiveness of positive allosteric modulators of metabotropic glutamate receptor 2/3 (mGluR2/3) in animal models of schizophrenia

Published: January 2025

Abstract
Schizophrenia (SZ) is a deleterious brain disorder characterised by its heterogeneity and complex symptomatology consisting of positive, negative and cognitive deficits. Current antipsychotic drugs ameliorate the positive symptomatology, but are inefficient in treating the negative symptomatology and cognitive deficits. The neurodevelopmental glutamate hypothesis of SZ has opened new avenues in the development of drugs targeting the glutamatergic system. One of these new therapies involves the positive allosteric modulators (PAMs) of metabotropic glutamate receptors, mainly types 2/3 (mGluR2/3). mGluR2/3 PAMs are selective for the receptor, present high tolerability and can modulate the activity of the receptor for long periods. There is not much research in clinical trials regarding mGluR2/3 PAMs. However, several lines of evidence from animal models have indicated the efficiency of mGluR2/3 PAMs. In this review, focusing on in vivo animal studies, we will specifically discuss the utilization of SZ animal models and the various methods employed to assess animal behaviour before summarising the evidence obtained to date in the field of mGluR2/3 PAMs. By doing so, we aim to deepen our understanding of the underlying mechanisms and the potential efficiency of mGluR2/3 PAMs in treating SZ. Overall, mGluR2/3 PAMs have demonstrated efficiency in attenuating SZ-like behavioural and molecular deficits in animal models and could be useful for the early management of the disorder or to treat specific subsets of patients.
Deep neural networks have an inbuilt Occam’s razor

Published: January 2025

Abstract
The remarkable performance of overparameterized deep neural networks (DNNs) must arise from an interplay between network architecture, training algorithms, and structure in the data. To disentangle these three components for supervised learning, we apply a Bayesian picture based on the functions expressed by a DNN. The prior over functions is determined by the network architecture, which we vary by exploiting a transition between ordered and chaotic regimes. For Boolean function classification, we approximate the likelihood using the error spectrum of functions on data. Combining this with the prior yields an accurate prediction for the posterior, measured for DNNs trained with stochastic gradient descent. This analysis shows that structured data, together with a specific Occam’s razor-like inductive bias towards (Kolmogorov) simple functions that exactly counteracts the exponential growth of the number of functions with complexity, is a key to the success of DNNs.
Metagenome-guided culturomics for the targeted enrichment of gut microbes

Published: January 2025

Abstract
The gut microbiome significantly impacts human health, yet cultivation challenges hinder its exploration. Here, we combine deep whole-metagenome sequencing with culturomics to selectively enrich for taxa and functional capabilities of interest. Using a modified commercial base medium, 50 growth modifications were evaluated, spanning antibiotics, physico-chemical conditions, and bioactive compounds. Whole-metagenome sequencing identified medium additives, like caffeine, that enhance taxa often associated with healthier subjects (e.g., Lachnospiraceae, Oscillospiraceae, Ruminococcaceae). We also explore the impact of modifications on the composition of cultured communities and establish a link between medium preference and microbial phylogeny. Leveraging these insights, we demonstrate that combinations of media modifications can further enhance the targeted enrichment of taxa and metabolic functions, such as Collinsella aerofaciens, or strains harboring biochemical pathways involved in dopamine metabolism. This streamlined, scalable approach unlocks the potential for selective enrichment, advancing microbiome research by understanding the impact of different cultivation parameters on gut microbes.
