Volunteer corn (Zea mays L.) is a competitive weed in corn-based cropping systems. Scientific literature does not exist about the water use of volunteer corn grown in different crops and irrigation systems. The objectives of this study were to characterize the growth and evapotranspiration (ETa) of volunteer corn in corn, soybean [Glycine max (L). Merr.], and sorghum [Sorghum bicolor (L.) Moench] under center-pivot irrigation (CPI) and subsurface drip irrigation (SDI) systems. Field experiments were conducted in south-central Nebraska in 2021 and 2022. Soil moisture sensors were installed at depths of 0 to 0.30, 0.30 to 0.60, and 0.60 to 0.90 m to track soil water balance and quantify seasonal total ETa. Corn was the most competitive, as volunteer corn had the lowest biomass, leaf area, and plant height compared with the fallow. Soybean was the least competitive with volunteer corn, as the plant height, biomass, and leaf area of volunteer corn in soybean were similar to fallow at 15, 30, 45, and 60 d after transplanting (DATr). Averaged across crop treatments, irrigation type did not affect volunteer corn growth at 15 to 45 DATr. Soil water depletion and ETa were similar across crop treatments with and without volunteer corn, as water was not a limiting factor in this study. The ETa of volunteer corn was the highest in soybean (623 mm), followed by sorghum (622 mm), and corn (617 mm) under CPI. The SDI had higher irrigation efficiency, because without affecting crop yield, it had 3%, 6%, and 8% lower ETa in soybean (605 mm), sorghum (585 mm), and corn (571 mm), respectively. Although soil water use did not differ with volunteer corn infestation, a soybean yield loss of 27% was observed, which suggests that volunteer corn may not compete for moisture under fully irrigated conditions; however, it can impact the crop yield potential due to competition for factors other than soil moisture.

Corn that is resistant to aryloxyphenoxypropionate, known commercially as Enlist™ corn, enables the use of quizalofop-p-ethyl (QPE) as a selective postemergence (POST) herbicide for control of glufosinate/glyphosate-resistant corn volunteers. Growers usually mix QPE with 2,4-D choline or glufosinate or both to achieve broad-spectrum weed control in Enlist corn. The objectives of this study were 1) to evaluate the efficacy of QPE applied alone or mixed with 2,4-D choline and/or glufosinate to control glufosinate/glyphosate-resistant corn volunteers in Enlist corn and 2) to determine the effect of application time (V3 or V6 growth stage of volunteer corn) of QPE-based treatments on volunteer corn control and Enlist corn injury and yield. Field experiments were conducted in Clay Center, NE, in 2021 and 2022. Quizalofop-p-ethyl (46 or 93 g ai ha−1) applied at the V3 or V6 growth stage controlled volunteer corn by ≥88% and ≥95% at 14 and 28 d after treatment (DAT), respectively. QPE (46 g ai ha−1) mixed with 2,4-D choline (800 g ae ha−1) produced 33% less than expected control of V3 volunteer corn in 2021, and 8% less than expected control of V6 volunteer corn in 2022 at 14 DAT. Volunteer corn control was improved by 7% to 9% using the higher rate of QPE (93 g ai ha−1) in a mixture with 2,4-D choline (1,060 g ae ha−1). QPE mixed with glufosinate had an additive effect and interactions in any combinations were additive beyond 28 DAT. Mixing 2,4-D choline can reduce QPE efficacy on glufosinate/glyphosate-resistant corn volunteers up to 14 DAT when applied at the V3 or V6 growth stage; however, the antagonistic interaction did not translate into corn yield loss. Increasing the rate of QPE (93 g ai ha−1) while mixing with 2,4-D choline can reduce antagonism.

As the proportion of women being victims of spousal violence in India is higher than men, laws are usually framed to safeguard women. However, men who have experienced physical spousal violence are not unheard of. The study aims to provide the nationwide prevalence of physical violence against husbands and the risk factors for such violence, using large-scale nationally representative ‘National Family Health Survey’ (NFHS 4) data. The study used descriptive, bivariate, logistic, and multilevel regression models with a random intercept clustering within states and households to explain the physical violence against husband. Sample size for the analysis was 62,716 currently married women aged 15–49 years. Findings revealed that in most of the states of India, physical spousal violence has increased over time. Behavioural characteristics like marital control, alcoholism, and childhood experience of parental violence have a consistent and strong role in explaining the experience of physical violence across states. With age, experience of violence against husbands increases. Differences in socio-economic characteristics do not have unidirectional effect on violence experienced by husbands across regions of India. Working women who are earning cash and having access to mobile phones perpetrate more physical violence in selected regions. Education shows a gradient on such violence perpetration, indicating that only after achieving a certain level of education, chances of violence reduce. Regionally contrasting social and economic risk factors in explaining violence strengthen the argument that violence is space and culture-specific, and development alone may not resolve violence unless the system is addressing the behavioural aspects. There is a need for supporting men experiencing domestic violence within the existing system facilities. Revisiting the present domestic violence laws and programmes for inclusivity is the need of the hour.

Kinetic models of polyatomic gas typically account for the internal degrees of freedom at the level of the two-particle distribution function. However, close to the hydrodynamic limit, the internal (rotational) degrees of freedom tend to be well represented just by rotational kinetic energy density. We account for the rotational energy by augmenting the ellipsoidal statistical Bhatnagar–Gross–Krook (ES–BGK) model, an extension of the BGK model, at the level of the single-particle distribution function with an advection–diffusion–relaxation equation for the rotational energy. This reduced model respects the $H$ theorem and recovers the compressible hydrodynamics for polyatomic gases as its macroscopic limit. As required for a polyatomic gas model, this extension of the ES–BGK model not only has the correct specific heat ratio but also allows for three independent tunable transport coefficients: thermal conductivity, shear viscosity and bulk viscosity. We illustrate the effectiveness of the model via a lattice Boltzmann method implementation.

The study primarily focuses on analyzing married women’s attitudes towards negotiating safer sex in two contexts. The first context is when a woman refuses to have sex with husband if she knows her husband has a sexually transmitted disease (STD) and the second is when she does so if she knows he has sex with other women. The study examined predictors of Indian women’s attitude towards negotiating safer-sex using data on 92,306 ever married women from the state module of the 2015-16, National Family Health Survey 4. Descriptive and multilevel logistic regression was used to understand the interplay between the attitude towards negotiation of safer sexual relationships with husband and the selected background characteristics with a primary focus on controlling behaviour and power relations. About 17% of women did not believe in negotiating safer sexual relations with the husband. An approximately equal proportion of ever-married women (79% each) believed in doing so under the two specific conditions, that is, if they knew the husband had an STD and they knew he had sex with other women. Multilevel regression analysis showed that women who had household decision-making power [AOR=0.71; p<0.01] and those whose husbands displayed low control towards them [AOR=0.91; p<0.05] were more likely to believe in negotiating safer-sex. Our findings suggest that women who have controlling partners or those who live under the umbrella of the husband’s authority lack the power to negotiate for safer sex. Interventions promoting sexual well-being must deal with negative male perceptions and expectations that perpetuate unhealthy sexual habits and marriage ties.

In existing historiography, the modernity discourse presents modern knowledge as being more economically efficient and technologically advanced compared to traditional skills. This theoretical lens has introduced a hierarchy of production and restructured the meaning of work and division of labour within the profession of weaving. Historically, the contexts of both the modern textile industry and traditional handloom weaving were interrelated in terms of technology and skills, but they have become increasingly segregated over the last two centuries. This article suggests an apparent distinction between “modernization” as a historical process and “modernity” as a condition. Analysis of the policies and prejudices of the colonial state explains the dynamics between producers, products, and techniques in the handloom textile sector of the United Provinces during the early twentieth century, as well as the impact of government policies, nationalist ideas, and global processes on the sector. Studying these interactions allows us to explore localized nuances pertaining to knowledge and skill that have often been ignored in historiography due to preconceived cultural, political, and institutional compartmentalization of craft communities.

COVID-19 serosurvey provides a better estimation of people who have developed antibody against the infection. But limited information on such serosurveys in rural areas poses many hurdles to understand the epidemiology of the virus and to implement proper control strategies. This study was carried out in the rural catchment area of Model Rural Health Research Unit in Odisha, India during March–April 2021, the initial phase of COVID vaccination. A total of 60 village clusters from four study blocks were identified using probability proportionate to size sampling. From each cluster, 60 households and one eligible participant from each household (60 per cluster) were selected for the collection of blood sample and socio-demographic data. The presence of SARS-CoV-2 antibody was tested using the Elecsys Anti-SARS-CoV-2 immunoassay. The overall seroprevalence after adjusting for test performance was 54.21% with an infection to case ratio of 96.89 along with 4.25% partial and 6.79% full immunisation coverage. Highest seroprevalence was observed in the age group of 19–44 years and females had both higher seroprevalence as well as vaccine coverage. People of other backward caste also had higher seropositivity than other caste categories. The study emphasises on continuing surveillance for COVID-19 cases and prioritizing COVID-19 vaccination for susceptible groups for better disease management.

Our selection and endogeneity corrected findings suggest that firms' political connections negatively influence their market value. We find that firms with a larger size, more operationally efficient in utilizing their assets, and those operating in more concentrated industries benefit more from the political connections than the otherwise corresponding firms. We also report that political connections do not influence firms' leverage choices. However, we find that politically connected firms with higher leverage have significantly lower market value. Further, we note that political connections help the firms operating in unregulated but more concentrated industries, probably to obtain ‘private benefits’, leading to their higher market value. Overall, our results indicate that the effect of political connections is not homogeneous across the sample firms. They also raise questions on the motivation of sample firms' political connections, suggesting that these firms probably obtain political connections for reasons other than enhancing their market value.

The role of skills has been eclipsed in the transition from an agrarian-craft economy rooted in hand-labour in small households to a modern political economy where productive work takes place outside the household, in offices and factories. Yet the ideological erasure of skilled work should not be confused with its actual disappearance. Precisely because such work was typically construed as private and unimportant, the embedded hierarchies and skills that shaped the handloom weaving industry in the North Indian province of United Provinces under colonial rule could escape systematic conversion to capitalist structures. Skill as human capital constituted the capitalist labour processes in the modern handloom industry, not as an abstract act, but as a historical experience. Handloom workers were reproduced, generationally, socially, and hierarchically, through the passing on of skilled labour within the unorganized informal sector of handloom weaving. Thus the stuff of community skills should move beyond its projection as either ‘endangered’ or ‘regressive’ to explore its access to capitalist structures and the exploitative networks that contain, transmit, and enable the production of skills.

Applause sign (AS) is a clinical phenomenon observed in several neurological disorders including progressive supranuclear palsy (PSP). We investigated the factors associated with AS in patients with PSP. PSP patients with AS showed greater motor impairment compared to those with negative AS. Global cognition including attention and memory were affected more in patients with positive AS. We also observed that gait variability, a known marker for unstable gait is pronounced in those who presented with positive AS. Hence, the clinician might expect a more severe disease and an unstable gait in a PSP patient presenting with AS.

Recent epidemiological studies analysing sex-disaggregated patient data of coronavirus disease 2019 (COVID-19) across the world revealed a distinct sex bias in the disease morbidity as well as the mortality – both being higher for the men. Similar antecedents have been known for the previous viral infections, including from coronaviruses, such as severe acute respiratory syndrome (SARS) and middle-east respiratory syndrome (MERS). A sound understanding of molecular mechanisms leading to the biological sex bias in the survival outcomes of the patients in relation to COVID-19 will act as an essential requisite for developing a sex-differentiated approach for therapeutic management of this disease. Recent studies which have explored molecular mechanism(s) behind sex-based differences in COVID-19 pathogenesis are scarce; however, existing evidence, for other respiratory viral infections, viz. SARS, MERS and influenza, provides important clues in this regard. In attempt to consolidate the available knowledge on this issue, we conducted a systematic review of the existing empirical knowledge and recent experimental studies following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The qualitative analysis of the collected data unravelled multiple molecular mechanisms, such as evolutionary and genetic/epigenetic factors, sex-linkage of viral host cell entry receptor and immune response genes, sex hormone and gut microbiome-mediated immune-modulation, as the possible key reasons for the sex-based differences in patient outcomes in COVID-19.
