Spectroscopic study of Be-shell stars: 4 Her and 88 Her
We present an optical spectroscopic study based on 41 spectra of 4 Her and 32 spectra of 88 Her, obtained over a period of 6 months. We estimate the rotational velocity of these stars from HeI lines in the blue spectral region (4000-4500 . We find that these stars are likely to be rotating at a fractional critical rotation of ?0.80. We measure the average I p/I c ratio to quantify the strength of the H? line and obtain 1.63 for 4 Her and 2.06 for 88 Her. The radius of the H? emission region is estimated to be Rd/R? ?5.0, assuming a Keplerian disk. These stars are thus found to be fast rotators with a relatively small H? emission region. We detect V/R variation of the H? spectral line during the observed period. We re-estimate the periods for both stars and obtain a period of ?46 d and its harmonic of 23.095 d for 4 Her, and a period of ?86 d for 88 Her. As these two cases are shell stars with binaries and have low H? EW with the emission region closer to the central star, the V/R variation and a change in period may be an effect of the binary on the circumstellar disk. 2016 National Astronomical Observatories, Chinese Academy of Sciences and IOP Publishing Ltd. -
The Lives behind the Luxurious Threads: Beleaguered Sustainability of Kashmirs Pashmina Artisans
Kashmir pashmina, sometimes referred to as "cashmere, in the West, is one of the most valuable cultural artifacts Kashmir has offered for centuries, and continues to be sought after. The fine pure pashmina has maintained its luxury status for centuries and is still a symbol of elegance in the international markets. The pashmina shawl is not just popular for its fiber, but also for the elegant embroidery stitched in myriad colors by skilled artisans. Despite this international acclaim, the pashmina artisans dwell in impoverished conditions and face the ever-growing challenges of power looms. This research article is a study of the social and economic barriers that contribute to the dire living conditions of the active Kashmiri pashmina artisans. Along with examining the deteriorating work condition of the artisans, this paper also looks at how these circumstances have a long-lasting impact on the pashmina shawl industry, thus leading to the degradation of an art form altogether. Finally, this paper studies the declining living conditions of the pashmina artisans by analyzing the data collected through a qualitative study incorporating cultural mapping tools like interviews, personal narratives, and literature review. The sample for the study was collected from Kashmir Haat, Srinagar, Kashmir by the researcher through interviews and discussions. 2023 Informa UK Limited, trading as Taylor & Francis Group. -
Psychological distress among college students of coastal district of Karnataka: A community-based cross-sectional survey
Background: Common Mental Disorders (CMDs) are frequent among adolescents and early adults. National Mental Health Survey of India 20152016 shows alarming results, especially for depression. This study explored the prevalence of psychological distress among college students. Additionally, the relationship between gender, living arrangement with psychological distress in various educational streams were explored. Materials and Methods: Through a cross-sectional community-based survey a total of 4839 college going students of various educational streams in Mangalore, Karnataka were assessed for psychological distress with Self-Reporting Questionnaire (SRQ-20). Results: Participants had median age of 19 (range = 9) years and the majority (59.5%) were females. The median SRQ score was 4 (range 20) and about 28.5% of students were found to be psychologically stressed. The suicidal ideation was reported by 13.6% of the students. Engineering and Arts/science/commerce students had significantly higher psychological distress scores as compared to health and allied sciences (k = 47.7; p < 0.001) and those who were staying with families (U = 2,687,648.5; p = 0.004) reported higher levels of psychological distress in comparison to those who were staying away from their families. Conclusion: Prevalence of psychological distress was high among students, especially non-medical students, students who were staying with their families, and those who were younger in age. A significant proportion of students had suicidal ideation, which needs early mental health interventions at the college level. 2018 -
Pollution Haven Hypothesis and the Bilateral Trade Between India and China
The pollution haven hypothesis is studied from a bilateral trade perspective in this study, taking the reference of two Asian giants, namely, India and China. For this purpose, trade in pollution-intensive industries is analysed using data collected from the United Nations Comtrade dataset based on Standard Industrial Trade Classification codes for 19922019. The analysis helps us argue that between the two, China's demand is more pollution-intensive and India is the major supplier of pollution-intensive products. From an environmental perspective, this implies that China seems to be gaining from trade, and India is becoming a pollution haven in its trade with China. The Author(s) 2023. -

A pair of kinematically related space curves
We investigate the relation between two types of space curves, the Mannheim curves and constant-pitch curves and primarily explicate a method of deriving Mannheim curves and constant-pitch curves from each other by means of a suitable deformation of a space curve. We define a "radius" function and a "pitch" function for any arbitrary regular space curve and use these to characterize the two classes of curves. A few non-trivial examples of both Mannheim and constant pitch curves are discussed. The geometric nature of Mannheim curves is established by using the notion of osculating helices. The Frenet-Serret motion of a rigid body in theoretical kinematics is studied for the special case of a Mannheim curve and the axodes in this case are deduced. In particular, we show that the fixed axode is developable if and only if the motion trajectory is a Mannheim curve. 2018 World Scientific Publishing Company. -
Acacia auriculiformisDerived Bimodal Porous Nanocarbons via Self-Activation for High-Performance Supercapacitors
Carbon nanomaterials derived from Acacia auriculiformis pods as electrodes for the electrochemical double-layer capacitors were explored. Four pyrolysis temperatures were set (400, 600, 800, and 1,000C) to understand the role of temperature in biomass pyrolysis via a possible self-activation mechanism for the synthesis of carbon materials. The carbon materials synthesized at 800C (AAC800) were found to exhibit a well-organized hierarchical porous structure, quantified further from N2 adsorption/desorption isotherms with a maximum specific surface area of 736.6m2/g. Micropores were found to be contributing toward enhancing the specific surface area. AAC800 exhibited a maximum specific capacitance of 176.7F/g at 0.5A/g in 6.0M KOH electrolyte in a three-electrode setup. A symmetric supercapacitor was fabricated using AAC800 as an active material in an organic electrolyte composed of 1.0M tetraethylammonium tetrafluoroborate (TEABF4) as a conducting salt in the acetonitrile (ACN) solvent. The self-discharge of the cell/device was analyzed from fitting two different mathematical models; the cell also exhibited a remarkable coulombic efficiency of 100% over 10,000 charge/discharge cycles, retaining ?93% capacitance at 2.3V.

Toxicological Profiling of Onion-Peel-Derived Mesoporous Carbon Nanospheres Using In Vivo Drosophila melanogaster Model
Toxicological profiling of the novel carbon materials has become imperative, owing to their wide applicability and potential health risks on exposure. In the current study, the toxicity of mesoporous carbon nanospheres synthesized from waste onion peel was investigated using the genetic animal model Drosophila melanogaster. The survival assays at different doses of carbon nanoparticles suggested their non-toxic effect for exposure for 25 days. Developmental and behavioral defects were not observed. The biochemical and metabolic parameters, such as total antioxidant capacity (TAC), protein level, triglyceride level, and glucose, were not significantly altered. The neurological toxicity as analyzed using acetylcholinesterase activity was also not altered significantly. Survival, behavior, and biochemical assays suggested that oral feeding of mesoporous carbon nanoparticles for 25 days did not elicit any significant toxicity effect in Drosophila melanogaster. Thus, mesoporous carbon nanoparticles synthesized from waste onion peel can be used as beneficial drug carriers in different disease models. 2022 by the authors. Licensee MDPI, Basel, Switzerland. -
Capacitive dominated charge storage in supermicropores of self-activated carbon electrodes for symmetric supercapacitors
The present work demonstrates a systematic study of pore size and specific surface area (SSA) of biomass-derived carbon and the choice of electrolyte concentrations affecting charge-storage mechanism (surface controlled and diffusion controlled) and electrochemical behaviour. Porous nanocarbons derived from Caesalpinia Sappan pods were synthesized by pyrolysis at 400, 600, and 800 C. Pyrolysis at 800 C was found suitable for the self-activation mechanism which formed bimodal porous nanocarbons with a high SSA of 675 m2/g. A maximum specific capacitance of 261.8 F/g at 0.5 A/g in 5.0 M KOH was observed for electrode materials synthesized at 800 C. The highlight of the study is the porous nanocarbon synthesized at 800 C which was found to possess micropores of size 0.71.0 nm playing a pivotal role in enhancing capacitance. The effect of electrolyte concentration on capacitance and charge storage mechanisms was also analyzed. A diffusion-controlled self-discharge model is established for supercapacitor devices. The single cell can power a red LED for 15 min; exemplifying the sustainable strategy of the utilization of abundant bio-waste to efficient energy storage devices. 2022 Elsevier Ltd -

What drives fish production Climatic indicators or economic indicators? Empirical evidence from India
Purpose This study examined the relative roles of climate and economic factors in driving fish production across Indian states from 2000 to 2020, with a disaggregated focus on inland and marine systems. It also explored the multivariate causal relationships between fish production, CO2 emissions, temperature, rainfall, GDP and fish consumption. Design/methodology/approach To investigate the interactions between fish production, climatic and economic indicators, we used two novel techniques, namely a two-stage instrumental variable approach (2SIV) and a JKS causality test. Findings Results showed that rising temperatures and carbon dioxide emissions significantly reduce fish production, while rainfall, state GDP and per capita fish consumption enhance it. A disaggregated analysis revealed that all variables of interest had a considerable effect on marine fish production, comparable with the results for overall production; however, rainfall has a negligible effect on inland fish production. This discrepancy reflects system-specific dynamics: monsoonal rainfall has a direct impact on marine fisheries through nutrient enrichment and stock availability, whereas inland aquaculture is predominantly influenced by managed economic inputs rather than rainfall variability. Furthermore, the findings demonstrated that marine production is more sensitive to climatic factors, whereas inland production is more elastic to economic variables. The JKS test revealed that incorporating climatic and economic indicators improves the accuracy of fish production predictions than relying solely on its past values. Research limitations/implications For the foreseeable future, these findings have significant policy ramifications. In addition to strengthening water resource management and encouraging climate-resilient practices, fisheries departments should allocate a larger percentage of their GDP to infrastructure development. Additional stimulation of production can be achieved by demand-side measures like nutrition campaigns and the inclusion of fish in public food programs. To maintain the sustainable growth of both marine and inland fisheries, a comprehensive policy framework that concurrently addresses climatic, economic and consumer aspects is necessary in light of the established multivariate causation. Finally, it is prudent for policymakers and other stakeholders to adopt climate-adaptive strategies for marine fisheries and direct investments and technological support towards inland aquaculture to align interventions with system-specific production drivers. Originality/value We contribute to the literature by integrating annual data for an empirical analysis across 32 Indian states and union territories. In addition, this study empirically disentangles the system-specific dynamics of Indian inland and marine fisheries. This aspect is often overlooked in existing literature because fisheries are often portrayed as a homogeneous industry. Moreover, the paper offers actionable insights for designing ecologically appropriate fisheries policies, while advancing academic debates on climateeconomyproduction relationships. 2026 Emerald Publishing Limited -
Solving Wordle Using Actor-Critic Reinforcement Learning
The popular word-game Wordle poses a difficult sequential decision-making problem with enormous discrete action spaces and partial feedback. In order to solve Wordle as efficiently as possible, this work explores the use of actor-critic reinforcement learning techniques. We develop two actor-critic variations, Vanilla Actor-Critic (AC) and Advantage Actor-Critic (A2C), and formulate Wordle as a Markov Decision Process. Through curriculum training on increasingly larger vocabulary, our method filters out invalid actions and guides learning by combining neural networks and symbolic reasoning. While the AC agent has 42.35 % success with an average guess of 4.85, the A2C agent has a 46.05 % success rate averaging 5.31 guesses per successful game. We show that, especially in the worst-case situations, batch-based A2C performs more robustly than stepbased AC. By effectively scaling from tiny vocabularies (50 words) to the entire Wordle lexicon (14,855 words), our neuro-symbolic technique demonstrates the efficacy of curriculum learning for challenging word games. 2025 IEEE. -

Exploring Symbolism and Myth in the Motifs of Pashmina Shawls: A Semiotic Analysis
The motifs adorning the pashmina shawl serve as a visual testimony to its association with Persian art, which significantly influenced the region. The advent of Islam in Kashmir during the 14th century ushered in a new era of artistic expression, wherein Muslim artists incorporated floral and arboreal motifs to enhance the esthetic appeal of textiles, architecture, and other facets of material culture. The main objective of this study is to examine the myth and narrative included in motifs found on Kashmiri pashmina shawls in light of Barthess mythological framework. The study reevaluates the paisley motif, attributing its creativity to Kashmiri artisans, and contributes significantly to documenting and conserving Kashmiri textile heritage. Through primary data analysis, it offers fresh insights into the motifs meanings and challenges conventional narratives. This study looked into the significance of floral motifs that are frequently used on pashmina shawls. This study depends upon the conclusions derived from the firsthand information collected from Kashmiri academicians, artisans, and secondary sources. 2025 Informa UK Limited, trading as Taylor & Francis Group. -
Stock Market Efficiency and COVID-19 with Multiple Structural Breaks: Evidence from India
The objective of the study is to investigate the influence of the coronavirus pandemic (endogenous crisis) on the stock market efficiency of India during the multiple break periods. The empirical analysis is performed using conditional heteroscedasticity and a small sample robust wild bootstrap automatic variance ratio test and automatic portmanteau test on a daily stock return data of two benchmark indices, that is, NIFTY and SENSEX. The empirical results demonstrate that the stock return of two indices deviates from market efficiency during some periods of the analysis, notably during the nationwide lockdown and peak periods of coronavirus cases in India. These findings indicate that changing stock market behaviour becomes more speculative and earns abnormal profits. To the best of the authors knowledge, this study provides the first evidence of investigating the variations in the stock market efficiency of India in response to this endogenous crisis. 2022 International Management Institute, New Delhi. -
The Impact of Financial Inclusion on Social and Political Empowerment: Mediating Role of Economic Empowerment
The primary purpose of this paper is to examine the impact of financial inclusion on womens social and political empowerment through the mediation of economic empowerment. A multidimensional index is created, using methodology by UNDP, to measure financial inclusion. Womens empowerment is measured through economic, social, and political dimensions. The datacollected from 545 women in slums through a structured schedule on a 5-point Likert scale. Exploratory and confirmatory factor analysis was performed to measure the construct. Multivariate statistical techniques such as regression were used to test the relationship between financial inclusion and women empowerment. The findings underscore a discernibly modest representation of women attaining high financial inclusion in slum settings. It is essential to recognise the pivotal role of economic empowerment as a partial mediator within the intricate interplay linking financial inclusion to social and political empowerment.This investigation is grounded in an examination of urban slums but has the potential for broader applicability, encompassing rural regions and locales proximate to financial centers within metropolitan areas to formulate a comprehensive framework for the empowerment of women. The findings underscore the impact of socio-economic and politico-economic factors on the incorporation of marginalized communities into the formal financial system. The current investigation results have implications for policymakers in developing countries that can serve as a valuable resource to enhance womens participation in the formal financial system. 2023, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature. -

The exploratory and confirmatory factor analysis were performed to validate the questions. The impact was tested using linear regression, and results of regression model indicated women's financial inclusion significantly contributes to their economic empowerment. The findings of the study indicate that women in urban slums do not lack access to financial institutions. The results of the study have critical implications for policymakers and stakeholders involved in the financial inclusion process such as bankers, self-help groups, and others to reorient themselves towards financial inclusion practices. 2023, IGI Global. -
Polyvictimization among Children and Adolescents in India: A Scoping Review of Prevalence, Consequences, and Risk Factors
Polyvictimization, defined as the experience of multiple forms of victimization such as physical, emotional, and sexual abuse, neglect, bullying, and exposure to violence, is a significant but underexplored concern in India. This scoping review set out to map the existing literature on polyvictimization among children and adolescents, with a focus on prevalence, psychological and social consequences, and contextual risk factors. Studies published between 2000 and 2025 were included if they involved Indian participants aged 018 years and addressed more than one type of victimization. The framework given by Arksey and OMalley (2005) was adhered to for the review. Twenty-three studies were included in the review, highlighting that children were often subjected to overlapping victimizations rather than single instances, with emotional and physical abuse most common, alongside neglect, sexual abuse, and bullying. These experiences were consistently linked to depression, anxiety, PTSD, behavioral problems, and poor social functioning, with risks heightened by gender, poverty, family conflict, and institutional settings. Overall, the findings show that polyvictimization is prevalent yet seldom studied as a distinct concept in India, underscoring the need for nationally representative research, clearer definitions, and integrated child protection policies that address the cumulative impact of multiple victimizations.

Assessing the impact of perceived parenting on the self-concept of college going young women
Self-concept (SC) constitutes the idea and beliefs one has about oneself. As the primary agents of socialization, parents play a crucial role in the development of self-concept of their children. The present study sought to explore the relationship of SC of college going young women in India with perceived parenting. Furthermore, it investigated whether perceived parenting significantly predicted SC. Data was collected from 150 college going young women across Delhi NCR (Mage=19.62, Age Range = 1821 years) using standardized measures of Parenting Scale and Self-Concept Questionnaire. The scales demonstrated high reliability using Cronbachs alpha for the given population. Statistical analyses (correlation and regression analysis) of the data revealed that perceived parenting of mothers and fathers both positively and significantly correlate and predict several dimensions of SC. Particularly, for participants perception of their mothers, carelessness vs. protection significantly predicted the total SC. For fathers, rejection vs. acceptance and freedom vs. discipline were major predictors. For both mothers and fathers, marital conflict vs. marital adjustment was a common predictor. The findings are indicative of the importance of perceived parenting in the development of SC. It also highlights that parenting is a shared responsibility and necessitates a balanced approach as both mothers and fathers play a vital role in shaping an individuals view of self.
