La construcción del capitalismo académico: Negociando la reforma universitaria en Perú (2014–2023)
Authors: Manky Omar , López Nattaly
Published: January 2025

¿Cómo se transforman las universidades latinoamericanas en el contexto del capitalismo académico? Exploramos esta pregunta desde una perspectiva sociológica, que enfatiza el papel de actores locales en la configuración de procesos de cambio social. A partir de una revisión sistemática de artículos periodísticos y de sesenta y seis entrevistas a expertos, docentes y autoridades universitarias, analizamos las dinámicas del sistema universitario peruano desde los orígenes de la reforma de 2014 hasta su crisis en 2023. Basándonos en el trabajo de Pierre Bourdieu, sostenemos que el capitalismo académico no es un fenómeno homogéneo ni inevitable, sino que sus lógicas dependen de negociaciones entre actores involucrados en el campo de la educación superior. En el contexto peruano, se observa un modelo rentista, que privilegia el lucro en el corto plazo, basado en cómo propietarios de universidades, rectores y académicos negocian y adaptan las exigencias de la reforma.
‘Suffering for the Sins of Others’: Lucius D. Bulkley, Syphilis Insontium, and Disease Destigmatisation in the Progressive Era United States
Authors: Bowen Elliott
Published: January 2025

Historical research on efforts to reduce the stigma associated with venereal disease (VD) generally dates these campaigns back to the 1930s. Within the United States, one of the earliest attempts to detach VD from its traditional association with sexual immorality occurred during the late nineteenth- and early twentieth-century, when the New York City dermatologist Lucius Bulkley coined the term syphilis insontium (‘syphilis of the innocent’) in the hopes of demonstrating that many of those who contracted this disease did so through non-sexual contact. Gaining widespread acceptance within the medical community, Bulkley’s ideas served as the intellectual foundation for a discursive assault on the prevailing belief that syphilis constituted the ‘wages of sin’—one designed to destigmatise the disease and to promote more scientific responses to it. However, the effects of this anti-stigma rhetoric were often counterproductive. Encouraging doctors to discern ‘innocence’ or ‘guilt’ through assessments of a patient’s character, syphilis insontium often amplified the disease’s association with immorality. With the passage of time, physicians became increasingly aware of these problems, and in the 1910s, a backlash against Bulkley’s ideas emerged within the American medical community. Yet even with the resultant demise of his destigmatisation campaign, discourses of ‘innocent syphilis’ continued to circulate, casting a long shadow over subsequent stigma reduction efforts.

Weak-line T Tauri stars (WTTS) exhibit X-ray flares, likely resulting from magnetic reconnection that heats the stellar plasma to very high temperatures. These flares are difficult to identify through targeted observations. Here, we report the serendipitous detection of the brightest X-ray flaring state of the WTTS KM Ori in the eROSITA DR1 survey. Observations from SRG/eROSITA, Chandra X-ray Observatory, and XMM-Newton are analysed to assess the X-ray properties of KM Ori, thereby establishing its flaring state at the eROSITA epoch. The long-term (1999–2020) X-ray light curve generated for the Chandra observations confirmed that eROSITA captured the source at its highest X-ray flaring state recorded to date. Multi-instrument observations support the X-ray flaring state of the source, with time-averaged X-ray luminosity (

$L_\mathrm{0.2-5\ keV}$

) reaching

$\sim 1.9\times10^{32}\mathrm{{erg\ s^{-1}}}$

at the eROSITA epoch, marking it the brightest and possibly the longest flare observed so far. Such intense X-ray flares have been detected only in a few WTTS. The X-ray spectral analysis unveils the presence of multiple thermal plasma components at all epochs. The notably high luminosity (

$L_\mathrm{0.5-8\ keV}\sim10^{32}\ \mathrm{erg\ s}^{-1}$

), energy (

$E_\mathrm{ 0.5-8\ keV}\sim10^{37}$

erg), and the elevated emission measures of the thermal components in the eROSITA epoch indicate a superflare/megaflare state of KM Ori. Additionally, the H

$\alpha$

line equivalent width of

$\sim$

$-5$

Å from our optical spectral analysis, combined with the lack of infrared excess in the spectral energy distribution, were used to re-confirm the WTTS (thin disc/disc-less) classification of the source. The long-duration flare of KM Ori observed by eROSITA indicates the possibility of a slow-rise top-flat flare. The detection demonstrates the potential of eROSITA to uncover such rare, transient events, thereby providing new insights into the X-ray activity of WTTS.
Robust and Efficient Mediation Analysis via Huber Loss
Authors: Wang WenWu , Peng Xiujin , Tong Tiejun
Published: January 2025

Mediation analysis is one of the most popularly used methods in social sciences and related areas. To estimate the indirect effect, the least-squares regression is routinely applied, which is also the most efficient when the errors are normally distributed. In practice, however, real data sets are often non-normally distributed, either heavy-tailed or skewed, so that the least-squares estimators may behave very badly. To overcome this problem, we propose a robust M-estimation for the indirect effect via a general loss function, with a main focus on the Huber loss which is more slowly varying at large values than the squared loss. We further propose a data-driven procedure to select the optimal tuning constant by minimizing the asymptotic variance of the Huber estimator, which is more robust than the least-squares estimator facing outliers and non-normal data, and more efficient than the least-absolute-deviation estimator. Simulation studies compare the finite sample performance of the Huber loss with the existing competitors in terms of the mean square error, the type I error rate, and the statistical power. Finally, the usefulness of the proposed method is also illustrated using two real data examples.
I Wish I Knew How it Would Feel to Drive the New Ford Fusion Hybrid: Making Sense of Music in Car Commercials
Authors: BROOKS MARC
Published: January 2025

As practised by Nicholas Cook, Philip Tagg, and Nicolai Graakjær, the analysis of advertising music has largely concentrated on how advertising works to communicate meaning. Within media and communications studies, such a focus is seen as a distraction — albeit a fascinating one. For Sut Jhally, for example, advertising has pernicious social and ecological effects and advertising scholars’ goal should be to understand ‘what work advertising does’ in order to mitigate them. This examination of a Ford automobile advert featuring Nina Simone’s ‘I Wish I Knew …’ (1967) shows how music analysis might contribute to this pressing project.
Popular Theopolitics and the Last Russian Tsar’s Intangible Remains
Authors: Kormina Jeanne
Published: January 2025

The article tells the story of the remains of the last Russian Tsar Nicholas II and his family, who were killed in Ekaterinburg in 1918, discovered in 1979, found again in 1991, solemnly buried in 1998, and canonized as saints by the Russian Orthodox Church in 2000. Thoroughly researched in the cause of official criminal investigation and identified with genetic tests in several labs in Russia and abroad, the royal remains have not been recognized by the Church. The failure to reach a consensus on the veracity of the remains of the Romanovs occurred in parallel with the inability to decide what to do with the mummified body of Soviet founder Vladimir Lenin, a contemporary of Nicholas II who has been kept in a mausoleum in the Red Square since the 1920s. Though, after 1991, voices have been raised for removing his body from this symbolic center of the country, no consensus has been reached so far as to where to move it and why. Revisiting Verdery’s famous work, the present article argues that such a movement necessitates a political commitment to voicing new notions of belonging and citizenship. The liminal status of these two bodies proves that the contemporary state in Russia is a continuation of both the Soviet and imperial state programs, not a new political structure like other post-socialist countries. Based on the works by Kantorowicz and Cherniavsky, this research develops the concept of popular theopolitics and aims to examine how people’s political and religious ontologies make use of the Tsar’s image.

Cystic Echinococcosis (CE) is a zoonotic disease caused by Echinococcus granulosus sensu lato. Diagnosing CE primarily relies on imaging techniques, and there is a crucial need for an objective laboratory test to enhance the diagnostic process. Today, cell-free DNAs (cfDNAs) have gained importance regarding their biomarker potential. This study aims to investigate the diagnostic capabilities of different cfDNA targets (Echinococcus-specific repeat sequences (mgs-4 and mgs-12) and partial fragment of repetitive sequence (EG1 Hae III)) and evaluate their diagnostic effectiveness when compared to a frequently used commercial E.granulosus-specific IgG ELISA. Seventy-six confirmed hepatic CE patients and healthy controls were included in the study. The EG1 Hae III region was assessed using nested PCR, whereas real-time PCR was employed to investigate other cfDNA targets. Analysis of the cfDNA-targeted tests indicated that mgs-4 demonstrated the highest diagnostic efficacy in distinguishing CE patients from healthy controls, achieving a sensitivity of 60.5% (p = 0.002). Combining ELISA with the mgs-4 target led to an increased sensitivity of 72.4% for distinguishing between CE patients and the control group. The sensitivity rates for ELISA and the three cfDNA targets varied among the groups. Active CE patients showed sensitivity rates of 52.9%, 52.9%, 23.5%, and 52.9% for ELISA, mgs-4, mgs-12, and EG1 Hae III assays, respectively. In contrast, inactive cyst patients displayed sensitivity rates of 21.4%, 66.7%, 19%, and 42.9% for the corresponding assays. The mgs-4, either alone or in combination with ELISA, demonstrated notably higher sensitivity values for CE diagnosis in all group comparisons compared to serology.
Structural biology inside multicellular specimens using electron cryotomography
Authors: Caspy Ido , Wang Zhexin , Bharat Tanmay A.M.
Published: January 2025

The electron cryomicroscopy (cryo-EM) resolution revolution has shifted structural biology into a new era, enabling the routine structure determination of macromolecular complexes at an unprecedented rate. Building on this, electron cryotomography (cryo-ET) offers the potential to visualise the native three-dimensional organisation of biological specimens, from cells to tissues and even entire organisms. Despite this huge potential, the study of tissue-like multicellular specimens via cryo-ET still presents numerous challenges, wherein many steps in the workflow are being developed or in urgent need of improvement. In this review, we outline the latest techniques currently utilised for in situ imaging of multicellular specimens, while clearly enumerating their associated limitations. We consider every step in typical workflows employed by various laboratories, including sample preparation, data collection and image analysis, to highlight recent progress and showcase prominent success stories. By considering the entire structural biology workflow for multicellular specimens, we identify which future exciting developments in hardware and software could enable comprehensive in situ structural biology investigations, bringing forth a new age of discovery in molecular structural and cell biology.
Ideological Self-Consciousness: Judith Shklar on Legalism, Liberalism, and the Purposes of Political Theory
Authors: Hall Edward
Published: January 2025

Judith Shklar once remarked that the mere presence of ideology is not objectionable but that pretended immunity to ideology is. I scrutinize this suggestion and Shklar’s subsequent view that social theorists should acknowledge that their ideological impulses influence both their methods of study and the questions they pursue. I begin by focusing on the different ways that Shklar characterizes ideology before turning to her critique of legalism. I then chart various ways that Shklar’s call for ideologically self-aware political theorizing feeds into her later work. I conclude by examining what ideological self-consciousness implies for our understanding of the purpose and limits of political theory.
Social Science and Its Critics: An Ideological Analysis
Authors: Blau Adrian
Published: January 2025

Why do many postpositivists caricature contemporary social science? Why make incorrect claims, for instance about social scientists avoiding values? Why discuss features that often no longer matter, such as seeking laws or predictions? Why reject extreme forms of social science without discussing more sensible forms? Why say little or nothing about scientific methodology, which is a great strength of recent social science? To explain such oversights and caricatures, philosophical analysis will not suffice. These are not isolated intellectual errors, but systematic ones, made by numerous scholars and fostered by social practices and institutional conventions. We thus need ideological analysis, which specializes in explaining institutionalized systems of belief. Speculative explanations are offered for postpositivist caricatures, including not only psychological factors, but also external ones (for example, the arrogance of many social scientists), limitations of language (for example, the ambiguity of the term ‘methodology’), rhetorical strategies (for example, genealogical approaches), and conventions (for example, bad citation practices).
How Are Ideologies False? A Reconstruction of the Marxian Concept
Authors: Leiter Brian
Published: January 2025

For Karl Marx, ideological forms of consciousness are false, but how and in what respects? Ideologies must include some beliefs in order to be false, even if not all the beliefs that are inferentially related in the ideology are false, and even if there are (causally) related attitudes in the ideology that are neither true nor false. “Ideological” beliefs, however, are not simply false; their falsity has the specific property of not being in the interests of the agents who accept the ideology. One can make two kinds of mistakes about interests. One can mistake what is in one’s intrinsic interest or one can mistake what is in one’s extrinsic interest (that is, the means required to realize one’s intrinsic interests). Marx is mostly, but not exclusively, focused on mistakes about extrinsic interests; this is important in understanding how “morality” (which is not a matter of beliefs, but attitudes) can be ideological for Marx. I illustrate this analysis with some of Marx’s paradigmatic examples of ideological mistakes and offer an account of Marx’s conception of “interests.”
The Explanatory Power of Ideology
Authors: Buchanan Allen
Published: January 2025

This essay explores the range of phenomena that can be explained by application of a suitably broad but contentful concept of ideology. According to this concept, an ideology is an evaluative map of the social world, typically featuring an ingroup-outgroup distinction, at least in the case of political ideologies. This concept allows for ideologies that support the existing order and those that challenge it, including revolutionary ideologies. I refute the claim that the concept of ideology is not needed because “voluntary servitude” can be explained as a failure of collective action. I show that ideologies can inhibit revolutionary action as well as stimulate and guide it. They can inhibit revolutionary action by convincing the oppressed that their predicament is natural or inevitable or that they are not being oppressed. They can stimulate and guide revolution by debunking oppression-supporting ideologies and by supplying moral motivation that avoids the calculation of costs and benefits that cause failures of collective action.
An Evaluation of LENA Start™ Using Measures Derived from Parent–Child Interactions
Authors: Kuchler Kirstin , Elmquist Marianne , McConnell Scott R. , Finestack Lizbeth H.
Published: January 2025

It is important to assess learning in both familiar and unfamiliar conditions to determine the extent of learning generalisation. In this study, we evaluated parent language outcomes of LENA Start™, a parent-implemented intervention, using distal measures derived from a parent–child free play interaction.

Forty-four parents and their child (mean: 20.8 months) participated in LENA Start™ or early childhood education curriculum intervention, in either English (n = 34) or Spanish (n = 10). We completed between- and within-group analyses using language and communication behaviour measures derived from parent–child interactions elicited outside the home with researcher-supplied materials (i.e., distal measures).

Group comparisons revealed significant differences on a subset of behavioural measures. Spanish-speaking parents in the LENA Start™ group demonstrated significant gains on three measures. While LENA Start™ has been associated with parent gains on proximal language measures, the results of this study reveal limited generalisation of skills based on distal measures.
The dynamics of initiation in caregiver–child conversational interactions
Authors: Chai Jun Ho , Jung Jongmin , Ko Eon-Suk
Published: January 2025

We investigated the dynamics of communicative initiation in infant−caregiver interactions across ages and language abilities. Analyses of 228 Language ENvironment Analysis (LENA) recordings from 141 Korean adult−child dyads (60 girls; aged 7−30 months) replicated the initiator effect reported in North American populations. This effect, demonstrated by longer utterances, more frequent speech, and shorter response times in self-initiated interactions for both children and adults, suggests potential cross-cultural consistency in this conversational dynamic and remained consistent across ages in most conversational measures. A focused analysis of 13–14 month-olds (N = 40) and their K-CDI scores revealed that the initiator effect in segment duration and number persisted across most vocabulary percentiles. Additionally, nuanced findings indicated that caregivers increased their input frequency and adjusted segment duration in adult-initiated conversations in tandem with children’s higher receptive abilities. The robustness of the initiator role across cultures, ages, and vocabulary abilities points to a fundamental aspect of human communication.

Published: January 2025

Hepatitis E virus (HEV) is one of the most common causes of viral hepatitis. We examined HEV seroprevalence and associations of sociodemographic and lifestyle characteristics with HEV immunoglobulin G (IgG) seropositivity in the Arab population. A cross-sectional single-centre study was conducted among adults in the Nazareth area during 2022. Blood samples were tested using the Altona Real-Star HEV-RNA and the Wantai IgG assays. Data on sociodemographics, health status, and lifestyle were collected using structured questionnaires.

Overall, 490 individuals (55.9% males) aged 18 − 96 (mean = 53.2, SD = 28.0) were enrolled. HEV IgG seropositivity was estimated at 21.4% (95% CI 17.9–25.3). No samples were HEV-RNA positive. The correlates of HEV IgG seropositivity were older age (prevalence ratio (PR) 1.07, 95% CI 1.04–1.09, P < 0.001) and consuming beef frequently (PR 2.81, 95% CI 1.40–5.63, P = 0.003). No associations were found between Arab religious groups (Muslim, Christian or Druze, representing different socioeconomic status and dietary habits) or pork consumption and HEV IgG seropositivity. In conclusion, HEV seropositivity was high in the Arab population, and assessing HEV in Ruminants, particularly cows, is warranted.
The money market in transition: from city-based market arbitrage to a central banking system in nineteenth-century Spain
Authors: Iglesias Emma M. , Maixé-Altés J. Carles
Published: January 2025

This research supports the singularity of the Spanish case. The lessons we can learn are a product of the short transition in the mid 1880s from a city-based monetary system (supported by private actors) to a central banking system in the absence of a developed banking system with a nationwide scope, unlike what occurred in the rest of Western Europe. Introducing market arbitrage, we provide novel evidence – using new data – of how price formation in city-based money markets was driven by more than one price. Furthermore, factors such as market conditions, political circumstances and the asymmetrical development of market potential in the Spanish economic geography also played an important role. We also show new empirical support that transaction cost reduction was not associated with improving efficiency during the 1875–85 period when city-based money markets were still operating. The inland payment system was struggling even before its takeover by the Bank of Spain.
What role did serious mental illness play in Jackson Pollock’s drip paintings? Abstract expressionism and possible links to serious mental illness and encrypted images (polloglyphs)
Authors: Stahl Stephen M. , Morrissette Debbi Ann , Jabali Jahon , Gates Jon A.
Published: January 2025

The link between creativity and serious mental illness (SMI) is widely discussed. Jackson Pollock is one example of a giant in the field of art who was both highly creative and experiencing an SMI. Pollock created a new genre of art known as abstract expressionism (“action painting”) defined as showing the frenetic actions of painting. The question arises whether his SMI played any role in the way he created his drip paintings, especially when he was overactive and manic. Furthermore, did visual hallucinations or enhanced visual perception associated with mania or psychosis facilitate Pollock in embedding and camouflaging images under layers of thrown paint? Seeing images in Pollocks drip paintings has been a controversy ever since these paintings were created. Some experts attribute this to pareidolia—perceiving specific images out of random or ambiguous visual patterns—a phenomenon known to be enhanced by fractal fuzzy edges such as seen in Rorschach ink blots as well as in Pollock drip paintings. So, are Pollock’s drip paintings merely giant Rorschach images, or did Pollock insert polloglyphs—images that are encrypted that tell a story about Pollock’s inner being—into his paintings and then disguise them with drippings? Here, we explore answers to these questions and discuss images that Pollock included in his earliest sketches and used repeatedly in his abstract paintings and later in his drip paintings to argue that these images are not accidental.
Spillovers on the mean and tails: a semiparametric dynamic panel modeling approach
Authors: Huang Yu-Fan , Wang Taining , Kumbhakar Subal
Published: January 2025

Recently, there has been a surge in interest in exploring how common macroeconomic factors impact different economic results. We propose a semiparametric dynamic panel model to analyze the impact of common regressors on the conditional distribution of the dependent variable (global output growth distribution in our case). Our model allows conditional mean, variance, and skewness to be influenced by common regressors, whose effects can be nonlinear and time-varying driven by contextual variables. By incorporating dynamic structures and individual unobserved heterogeneity, we propose a consistent two-step estimator and showcase its attractive theoretical and numerical properties. We apply our model to investigate the impact of US financial uncertainty on the global output growth distribution. We find that an increase in US financial uncertainty significantly shifts the output growth distribution leftward during periods of market pessimism. In contrast, during periods of market optimism, the increased uncertainty in the US financial markets expands the spread of the output growth distribution without a significant location change, indicating increased future uncertainty.
When “Old” Constructivism Was New: Reflections on Classical Constructivism
Authors: Finnemore Martha , Wendt Alexander
Published: January 2025

New lines of theorizing in international relations don’t appear very often. Realism proudly proclaims a lineage of 2,500-odd years. Liberalism, in its various forms, traces its roots back several centuries. The appearance and spread of constructivism in the 1990s thus invite explanation. In this essay we explore the “construction of constructivism”—both the conditions of possibility for intellectual change and the goals of scholars proposing it. Constructivism’s success was both unexpected and, in some ways, unintended. Proponents of existing theories remained (and remain) confident in their own tools and early constructivists often had modest goals. Constructivism took off for at least two broad reasons. One was the intellectual landscape of the late 1980s and early 1990s. This was a period when IR theory in the United States had sharply narrowed its concerns, leaving mainstream scholarship on the back foot when the USSR collapsed, and the Cold War ended. The second set of reasons lay in the nature of the constructivist ideas, themselves. Intellectually, constructivist ideas had a plasticity and capaciousness that other IR theories did not. Theoretically, it is a social theory, not specific to IR, which made it useful for tackling a broad range of problems. Empirically, it was portable and open to political analysis at all levels and in all places. Methodologically, it was pluralistic; scholars can and have used diverse methods to explore its claims. In this situation, constructivist scholars, overwhelmingly young and untenured, worked hard to carve out a niche for themselves in the field. That these ideas caught on and became broadly popular has surprised us as much as anyone.
The Radical Right Goes Global (and Local)
Authors: Art David
Published: January 2025

Twenty years ago, there were around 80 million people—mostly Italians—living in a democracy where right-wing populists governed nationally. By 2020, that number had grown to 2.5 billion with right-wing populists in power in the largest (India), second largest (United States), fourth largest (Brazil), and sixth largest (Philippines) democracies in the world. As Cecilia Lero writes, “countries in the Global South, and the Philippines and Brazil in particular, have not had recent large waves of immigration or notable demographic shifts and have experienced real income growth across all classes over the past 15 years” (110). Thus, the rise of right-wing populists like Rodrigo Duterte and Jair Bolsonaro in “two countries previously considered relative success stories of democratization in their region” is puzzling and one of the key themes of Right-Wing Populism in Latin American and Beyond, edited by Anthony Pereira. Although half of the contributors are based in Brazil, and nearly all work in the country, the volume is truly comparative, as populism in Columbia, Peru, Italy, India, the Philippines, the United States, and Venezuela is covered in some depth. Substantive themes include right-wing populist responses to COVID—including “medical populism” and the creation of a transnational “Hydroxychloroquine Alliance”—along with standard chapters on theory, political economy, and institutions. It is one of the first books to chart the largest change in right-wing populism over the last decade: its rise to governance in democracies in the Global South.

Facing the paradox of professionalizing peer roles in MH services: how addressing self-disclosure with self-determination theory might help
Authors: Moran Galia S.
Published: January 2025

Peer Support Workers (PSWs) play a crucial role in recovery-oriented mental health services. They offer support and hope by sharing their personal experiences and recovery journeys. However, transitioning from voluntary self-help roles to paid positions within statutory systems is not merely a technical shift. This change creates inherent tensions and conflicts, stemming from the integration of a peer model within a medical framework. I refer to the interface between these models as the “Professional-Peer Paradox” (PPP). At its heart, this paradox questions whether and how PSWs can integrate a role that relies on self-disclosure of shared lived experiences within a system rooted in professional knowledge norms delivered unidirectionally to service recipients. Using a whole organizational approach, I propose leveraging the autonomy-supportive environment concept from self-determination theory (SDT; Deci & Ryan, 2000) to promote self-disclosure in mental health services. I highlight the complexities involved in Peer Support Workers’ (PSWs) use of self-disclosure (lived experience) within statutory mental health (MH) services. I suggest that PSWs can better commit to their unique roles by structuring multiple peer roles with varying levels of self-disclosure and creating a culture that fosters peer practice. Overall, applying a SDT systems’ framework to the practice of self-disclosure can enhance the occupational identity of PSWs, establishing their unique position within the spectrum of mental health professions globally.

Water is essential for sustaining life and required for carrying out basic daily activities. Even though water covers the vast majority of the earth’s surface, the availability of fresh water, which is necessary to maintain human activities, is limited, making it a scarce resource. Climate change, overexploitation of groundwater, and population growth are all putting significant pressure on natural water sources, which pose a serious threat to various sectors of society, especially in agriculture. Future projections of freshwater availability indicate agriculture production will suffer a significant shock globally, including in India, leading to a threat to food security and sustainability. To ensure the sustainability of this vital resource, it is crucial to use water sensibly. Moreover, it is essential to adopt certain strategies to manage agricultural water use effectively. This includes adopting various water-efficient techniques such as ‘micro-irrigation’, ‘irrigation scheduling’, ‘conservation agriculture’, ‘crop switching’ and so on. In this review, firstly, we discuss water scarcity and its types, causes, crisis for water shortages and hindrance to sustainable development from a global perspective emphasizing the Indian scenario as a developing nation. Secondly, we elaborated our discussion on water scarcity in agriculture including the impacts of water scarcity on agricultural production and its connection to climate change, population growth, and overexploitation of natural resources globally focusing on the Indian scenario. In addition, innovative water management practices and adaptation strategies to manage agricultural water use, constraints, and the need for further research are also covered. It is anticipated that this review will benefit researchers and policymakers by providing useful information on the impacts of water limitation and adoption strategies.
Critical period for Italian ryegrass (Lolium perenne L. spp. multiflorum) control in winter wheat in North Carolina
Authors: Contreras Diego J. , Leon Ramon G. , Post Angela R. , Everman Wesley J.
Published: January 2025

Field studies were conducted in North Carolina to determine the critical period of weed control (CPWC) for Italian ryegrass in winter wheat. Soft red winter wheat was planted in late fall in 2017 and 2018 in no-till fields near Salisbury, NC. Treatments consisted of allowing weeds to grow from crop emergence for different intervals until removal (“weedy”), maintaining “weed-free” conditions from crop emergence for the same intervals, and then letting the weeds emerge and compete with the crop for the duration of the season. In 2017, weed removal occurred in 2-wk intervals from crop emergence up to 18 wk after crop emergence (WAE) and 3-wk intervals up to 18 WAE in 2018. Additional biological measurements, including Italian ryegrass density and height, were collected at 6, 12, and 18 WAE to characterize the effect of crop-weed interactions on the CPWC and weed populations. Nonlinear regression analysis was conducted to relate the timing of weed removal and yield loss. The analysis was carried out using growing degree days (GDDs) accumulated at corresponding WAE. Italian ryegrass density ranged from 292 to 824 plants m−2, which created intense competitive conditions with wheat. In the absence of weed control, yield loss surpassed 60%. Using 5% yield loss as an accepted threshold, the CPWC for Italian ryegrass in no-till planted wheat was estimated to be from 1,100 to 1,900 GDD. This relatively short period makes it possible to reduce weed control intensity if control actions are properly timed.
Particle Sedimentation in a Fluid at Low Reynolds Number: A Generalization of Hindered Settling Described by a Two‐Phase Continuum Model
Authors: Huber C. , Parmentier E. M. , Florez D.
Published: January 2025

Particle‐fluid separation by settling is a ubiquitous process in Earth and Planetary Sciences. The settling velocity of particles is controlled by a balance between buoyancy and drag forces. Since the seminal work of George Gabriel Stokes, parameterizations for the reduction of particle velocities caused by viscous dissipation due to mutual interactions have been described by a non‐linear mapping between particle volume fraction and separation velocity. We argue that these parameterizations neglect important physical behavior at high particle volume fractions (>80% of the maximum packing) and are only appropriate when considering suspensions where the particle volume fraction does not evolve in space or time. We introduce a more general model that accounts for the energy dissipation caused by changes in local particle volume fraction, which introduces a new term similar to the compaction term at higher particle volume fraction. This term depends on a consolidation/compaction viscosity that measures the resistance to changes in solid volume fraction. We derive closure equations for this compaction viscosity under dilute and concentrated particle volume fraction limits. Numerical simulations show that the extended hindered settling model predicts two significant differences compared to traditional hindered settling. First, while the steepening of particle volume fraction fronts remains, a dynamic instability is also generated at the front. Second, the rate of growth and structure of a cumulate layer growing above a no‐flux boundary is affected by the compaction‐like term and predicts the trapping of a higher volume fraction of interstitial melt in a correspondingly thicker cumulate layer.

Powder snow avalanches (PSAs) radiate infrasound energy, yet the source mechanism remains unclear, limiting hazard monitoring and mitigation with infrasound‐based technologies. Here, we analyze a unique data set from a large PSA to improve the understanding of the source mechanism. Through comparison of cluster activity within the airborne layers of the PSA and the recorded infrasound signal in the frequency domain, we demonstrate that infrasound is mainly generated from particle clusters suspended by turbulent eddies or ejected from the denser basal layer. Further correlating infrasound amplitudes with radar‐derived spatial distributions of these clusters, we reveal a distributed source extending hundreds of meters behind the avalanche front. Additionally, we establish a relationship between infrasound and kinetic energy of suspended particles. These findings deepen our understanding of the complex dynamics of infrasound generation, offering valuable insights for avalanche detection and early warning strategies, and fundamental comprehension of PSA dynamics.

The global 3‐dimensional structure of the concentric traveling ionospheric disturbances (CTIDs) triggered by 2022 Tonga volcano was reconstructed by using the 3‐dimensional computerized ionospheric tomography (3DCIT) technique and extensive global navigation satellite system (GNSS) observations. This study provides the first estimation of the CTIDs vertical wavelengths, ∼736 km, which was much larger than the gravity wave (GW) vertical wavelength, 240–400 km, estimated using ICON neutral wind observations. Notable trend with the variation of azimuth was also found in horizontal speeds at 200 and 500 km altitudes and differences between them. These results imply that (a) the global propagation of Lamb waves determined the arrival time of local ionospheric disturbances, and (b) the arriving Lamb waves caused vertical atmospheric perturbations that are not typical of GWs, resulting in local thermospheric horizontal wave propagation which is faster than the Lamb wave propagation at lower altitudes.

We examined three descending positive leaders at distances of 5–11 km and three descending negative leaders at distances of 6–7 km, all simultaneously imaged by high‐speed framing cameras operating in the visible and UV ranges. UV images (290–370 nm) of the positive leaders each exhibited a strong embellishment at the lower channel end, which was not observed in the corresponding visible images (480–800 nm). In contrast, none of the negative leaders exhibited channel embellishment in the UV range and their morphology in UV was similar to that in the visible. Additionally, no embellishment was seen in four negative leaders imaged in UV only. The observed UV embellishment, which is likely to be the streamer zone at the positive‐leader tip, appeared to undergo expansion‐contraction cycles. We attributed the lack of detectable streamer‐zone emission in the UV range in negative leaders to a much lower streamer generation rate compared to positive leaders.
Uniting Surface Properties With Hydrodynamic Roughness in Shallow Overland Flow Models

Describing flow resistance from the properties of an underlying surface is a challenge in surface hydrology. Runoff models must specify a resistance formulation or “roughness scheme”—describing the functional relationship between flow resistance and flow depth/velocity—and its parameters. Uncertainty in runoff predictions derives from both the selected roughness scheme (e.g., Darcy Weisbach, Manning's, or laminar flow equations), and its parameterization with a roughness coefficient (e.g., Manning's ). Both choices are informed by model calibration to data, usually discharge, and, if available, velocity. In this study, a Saint Venant Equation‐based runoff model is calibrated to discharge and velocity data from 112 rainfall simulator experiments. The results are used to identify the optimal roughness scheme among four widely‐used options for each experiment, and to explore whether surface properties can be used to select the optimal roughness scheme and its coefficient. Among the tested roughness schemes, a transitional flow equation provided the best fit to the plurality of experiments. The most suitable roughness scheme for a given experiment was not related to measured surface properties. Regression models predicted the calibrated roughness coefficients with adjusted values between 0.48 and 0.54, depending on the roughness scheme used. Litter cover was the best predictor of the roughness coefficient, followed by soil cover and average canopy gap size. The results suggest that selection of an optimal roughness scheme based on surface properties alone remains difficult, but that once a scheme is selected, roughness coefficients can be estimated from surface properties.

Escalating climate and anthropogenic disturbances draw into question how stable large-scale patterns in biological diversity are in the Anthropocene. Here, we analyse how patterns of reef fish diversity have changed from 1995 to 2022 by examining local diversity and species dissimilarity along a large latitudinal gradient of the Great Barrier Reef and to what extent this correlates with changes in coral cover and coral composition. We find that reef fish species richness followed the expected latitudinal diversity pattern (i.e., greater species richness toward lower latitudes), yet has undergone significant change across space and time. We find declines in species richness at lower latitudes in recent periods but high variability at higher latitudes. Reef fish turnover continuously increased over time at all latitudes and did not show evidence of a return. Altered diversity patterns are characterised by heterogeneous changes in reef fish trophic groups across the latitudinal gradient. Shifts in coral composition correlate more strongly with reef fish diversity changes than fluctuations in coral cover. Our findings provide insight into the extent to which classic macroecological patterns are maintained in the Anthropocene, ultimately questioning whether these patterns are decoupling from their original underlying drivers.

The recent outbreak of Marburg virus (MARV) in Rwanda underscores the need for effective countermeasures against this highly fatal pathogen, with case fatality rates reaching 90%. Currently, no vaccines or approved treatments exist for MARV infection, distinguishing it from related viruses like Ebola. Our research demonstrates that the oral drug obeldesivir (ODV), a nucleoside analog prodrug, shows promising antiviral activity against filoviruses in vitro and offers significant protection in animal models. In this study with cynomolgus macaques (n=6), a 10-day regimen of once-daily ODV, initiated 24 hours post-exposure, provided 80% protection against a thousand-fold lethal MARV challenge, delaying viral replication and disease onset. Transcriptome analysis revealed that early adaptive responses correlated with successful outcomes. Compared to intravenous options, oral antivirals like ODV offer logistical advantages in outbreak settings, enabling easier administration and broader contact coverage. Our findings support ODV's potential as a broad-spectrum, oral postexposure prophylaxis for filoviruses.
Porous carbons with complex 3D geometries via selective laser sintering of whey powder

In addition to the inherent limitations of carbons to melt or flow, a vast majority of carbon precursors deforms during carbonisation, with stereolithography of thermoset resins being the preferred technology for 3D printing of carbons. An alternative is now presented with the possibility of using a melting-based technology, selective laser sintering (SLS), to fabricate 3D structures that withstand carbonisation. The key factor that makes this happen is whey powder, a natural, abundant and cheap by-product of the dairy industry. When heating the whey powder with a laser at 180–200 ºC for a few seconds, whey particles sinter, and 3D structures are obtained layer-by-layer. Carbonisation of the sintered whey structures brings about 3D porous carbons with excellent mechanical properties that preserve the SLS printed form albeit an isotropic shrinkage (approx. 23%). Melanoidins are identified as responsible for both the sintering and the thermoset behaviour during carbonisation of the whey powder.

The most common diagnostic error of IIH is inaccurate funduscopic examination. Moreover, IIH could be diagnosed without papilledema. Trans orbital sonography could be used as a non-invasive and cheap tool for discovering increased ICP (intracranial Pressure). Aim of our study was discovering the changes in ultra-sonographic indices and which one could predict the increased ICP. Sixty-eight patients were diagnosed as definite IIH and 68 healthy volunteers are included in the study who had the same sex and age. ONSD, peak systolic velocity (PSV), end diastolic velocity (EDV), and resistance index (RI) were estimated by transorbital color Doppler. Multivariate linear regression was used to discover the predictors of increased ICP. ROC curve was plotted for the predictor. A statistically significant difference was found between IIH patients and controls regarding ONSD, EDV and RI. Multivariate linear regression revealed that ONSD is the only predictor of increased CSP pressure. Its cut-off value indicating high ICP was 5.7 mm on Rt and Lt eye (AUC: 0.916; 95% confidence interval 0.867–0.965; p < 0.001; 90% sensitivity, 80% specificity at Rt eye. AUC: 0.902; 95% confidence interval 0.845–0.958; p < 0.001; 91% sensitivity, 80% specificity at Lt eye).
