Reliance on biomass fuel remains high in many developing countries, like India. Shifting to clean fuel has widely recognized benefits for women in saving time, improving health, and creating a better environment. Other benefits to women in the form of increasing empowerment are a relatively under‐researched area. Using data from the nationally representative National Family Health Survey (2019–21) in India, this study uses endogenous treatment effect models to explore the causal effect of shifting to clean fuel on awareness, work, mobility, decision‐making and financial autonomy. Analysis reveals significant gains in all dimensions, particularly in women's mobility and decision‐making. The gains are relatively higher among less educated women, those from poor households, and those belonging to socially advantaged groups. Focusing on gains to empowerment will motivate women to adopt clean fuel and enable a holistic transformation of society through the simultaneous attainment of several Sustainable Development Goals.

This study examines the coverage and effect of cash transfers and food subsidies in India during the COVID-19 pandemic. It is based on a primary survey of rural women in the state of Bihar – an underdeveloped state with poor public delivery systems – undertaken in January–March and September–November 2020. Although the coverage of cash transfers was wider than that of food subsidies, respondents receiving cereals and pulses under the Public Distribution System reported a lower probability of suffering from food insecurity vis-à-vis cash subsidies. The study suggests that food subsidies may be more effective when supply chains break down. [ABSTRACT FROM AUTHOR]

Initial studies have reported an increase in the incidence of mental health problems during the early months of COVID-19. Longitudinal studies of changes in mental health undertaken in Low and Middle Income countries during the pandemic remains an under-researched area. The current study examines changes in mental health among adult residents of metropolitan cities of India, a middle-income country reporting the second-highest COVID cases and third-highest fatalities, during the pandemic. Data was collected, based on a telephonic survey using the internationally accepted abridged Depression Anxiety Stress schedule (DASS-21), in August and September 2020 and July-August 2021. The sample size is 994. The data was analysed using an ordered logit model. At the onset of the pandemic, high levels of anxiety, stress and depression prevailed; their levels reduced after one year. Respondents who have experienced a decline in economic fortunes, have family members with pre-existing co-morbidity or had COVID in the family are significantly less likely to report improvement in mental health; less-educated respondents are also vulnerable. Specific sub-groups, identified as at risk, need monitoring and continued provisioning of tailor-made mental health services addressing their specific needs. Relief measures targeting economically affected households are also required. [ABSTRACT FROM AUTHOR]

Self‐help groups (SHGs) are used as instruments for changes in health‐related behaviour. We evaluated the impact of the Health and Nutrition Strategy of JEEViKA on the dietary practices of infants in rural areas of Bihar. Propensity score matching revealed that the probability of exclusive breastfeeding until 6 months and starting complementary feeding after 6 months was higher by 5% and 3%, respectively, if the respondent was an SHG member. The average treatment effects on treated using attendance in meetings as the treatment variable found that the programme had increased breastfeeding only, with there being peer effects also. The study recommends encouraging attendance in SHG meetings. [ABSTRACT FROM AUTHOR]

The main contribution of this paper is inspired by the question "Can six-phase doubly-fed induction generator (6-Φ-DFIG) work in unhealthy (with one or more phases open-circuited) conditions or not?". The conventional DFIG cannot work under open-phase conditions, while the novel 6-Φ-DFIG can operate with one or more phases open-circuited. This paper addresses the mathematical and simulation-based modelling of the novel 6-Φ-DFIG operation under open-phase faults. Moreover, the advantages of the novel 6-Φ-DFIG are also illustrated in this paper. Simulation results validate the mathematical modelling of the novel 6-Φ-DFIG due to an open phase for the post-fault conditions. To the best of the authors' knowledge, the proposed novel 6-Φ-DFIG has never been modelled and simulated for open-phase conditions anywhere in the world. [ABSTRACT FROM AUTHOR]

Most studies on intimate partner violence (IPV) and its drivers have focused on individual-and household-level characteristics of the victim. Recent studies have acknowledged that it is a community-level phenomenon, using spatial analytical methods to analyze community-level determinants of IPV and its geographic dimensions. Such studies provide mixed evidence on the impact of different factors and need to be supplemented by similar studies—particularly in South Asian countries where IPV is common. The present study examines district-level variations in the incidence of various forms of IPV and identifies its determinants in India, a fast-growing South Asian country with poor gender indicators. The study combines data from the National Family Health Survey, District Level Household Survey, and the decadal Census. It applies spatial analytical methods such as the Global Moran's I, Getis-ord statistic, and Multivariate Local Geary to determine the nature of the spatial distribution of different categories of IPV. Spatial regression models are used to identify the community-level predictors of each category of IPV. The study finds non-random overlapping spatial clusters in the eastern part of India. The study also finds that neighborhoods characterized by low empowerment levels, and with a high child sex ratio, road connectivity, and proportion of socially marginalized groups are more likely to exhibit high levels of all types of IPV—although the impact of these determinants varies across districts. Furthermore, spill-overs in the incidence of IPV between neighboring districts are also observed. The study concludes by recommending the use of localized policies, rather than broad national or state policies, in reducing IPV. [ABSTRACT FROM AUTHOR]

Aim: The aim of this study was to compare the effectiveness of rotary instrumentation over manual instrumentation with ultrasonic irrigation on incidence, duration, and intensity of postendodontic pain (PEP). Subjects and Methods: Eighty patients, with asymptomatic irreversible pulpitis in maxillary anterior teeth, were selected and treated with single-visit endodontic treatment. Patients were randomly divided into 2 groups (40 each), Group A (K files using step-back technique) and Group B (ProTaper Next using crown-down technique) along with passive ultrasonic irrigation. Patients were recalled, examined, and asked to fill up questionnaire after 24 h, 48 h, and 7 days. On the basis of response given in the feedback forms, incidence, duration, and intensity of PEP were evaluated. Results: Statistical analysis of the data was carried out using Chi-square test, and level of significance (P < 0.05) was evaluated. More incidence of pain was noticed in Group A when compared with Group B. Significant difference found between two groups (χ2 = 22.759; P = 0.001). There was also statistically significant difference between two groups at different time intervals. Conclusion: Both instrumentation techniques under investigation cause PEP. The incidence of pain was more in manual technique than rotary technique. The duration of pain was higher in manual group than rotary group at different time intervals. [ABSTRACT FROM AUTHOR]
