Mitigating Subjectivity and Annotation Inconsistencies in Sentiment Analysis via an SVM-RoBERTa Ensemble
This research addresses a main limitation in the Natural Language Processing that is the impact of subjectivity and annotation inconsistencies on the accuracy of the sentiment classification. We did a systematic comparison of two fundamentally different architectures. A traditional feature based Support Vector Machine and a deep contextual fine tuned RoBERTa transformer using a challenging, noisy, real-world Twitter dataset. This corpus retains ambiguity and sarcasm on purpose and serve the crucible for testing model robustness. We developed a soft voting ensemble method that combines the probability scores from both models to obtain the best predictive capabilities. The results showed a clear technological hierarchy. The RoBERTa model with its deep semantic grasp outperformed the SVM by a substantial margin achieving 90% accuracy against 83.5% accuracy. But the hybrid ensemble model attained the highest overall accuracy of 91.35% and showed better reliability across all the sentiment classes. These findings shows that a hybrid approach fusing a transformer's nuanced understanding with the stabilization provided by ensemble learning is the most effective and robust method for mitigating data imperfections in modern sentiment analysis. 2025 IEEE. -

Optical and infrared studies of herbig Ae/Be stars
The work makes use of the unprecedented capability of the Gaia mission to study various properties of Herbig Ae/Be stars. We placed the Herbig Ae/Be stars in the Gaia color-magnitude diagram and accurately estimated their age and mass. The mass accretion rate is calculated from Hα line flux measurements of 106 HAeBe stars. The mass accretion rate is found to decay exponentially with the age of Herbig Ae/Be stars. Further, the immediate neighborhood of two Herbig Ae/Be stars, V1787 Ori and IL Cep, are studied using the astrometric and photometric data from the Gaia mission. We discovered a low mass binary companion to V1787 Ori using the analysis of distance and proper motion values from Gaia DR2. The mass ratio of the coeval binary system is found to be 0.23. Such a skewed mass ratio system is rarely identified in Herbig Ae/Be binary systems. The method of identification and characterization of the V1787 Ori wide binary system opens up the possibility of identifying more such systems. The HBe star IL Cep tells a much more complex story. The star is identified with a cluster of low mass stars associated with it. We identified 79 co-moving stars that are coeval to IL Cep, within 2 pc radius, from the analysis of Gaia EDR3 astrometry. The triggered star formation process called the "Rocket effect" caused by a massive star HD 216658 is identified to be the cause of the clustered star formation near IL Cep. The effect of this process is demonstrated for the first time using the proper motion data from Gaia. The immediate neighborhood of Herbig Ae/Be stars is identified as the formation region of long-chain carbon molecules such as Fullerenes and Polycyclic Aromatic Hydrocarbons. -

Environmental justice and rural poverty: Socioeconomic drivers of environmental impact in the Indian Sundarbans
This study explores the complex relationship between environmental degradation and rural poverty through the perspective of environmental justice in the Indian Sundarbans. This region is recognized for its ecological richness but faces significant socio-economic vulnerabilities. Despite the areas abundant natural resources and biodiversity, rural poverty persists, shaping resource use patterns and environmental outcomes. The main objective is to examine how rural poverty affects the environment and to identify key socio-economic factors influencing ecosystem services in the region. A stratified sampling technique was used to select households and data were collected through structured questionnaires and focus group discussions. Household-level CO2 emissions were estimated from domestic fuel and energy consumption. Results show nearly half of the household emissions come from burning firewood for cooking and heating. These practices not only release stored carbon but also reduce the regions carbon removal capacity, directly contributing to environmental degradation. The people of the Sundarbans pollute far less than the national average, but they face the harshest impacts of climate change: rising sea levels, salinity intrusion and ecosystem decline that highlighting a profound environmental injustice. Among rural households, the extremely poor emit more CO2 than the less poor because they depend on cutting trees to survive, further weakening the regions natural carbon sink. A log-linear regression model identifies education, dependency ratio, livelihood diversification and access to transport as major factors influencing natural resource-based income. The findings suggest that poverty, isolation and low education reinforce ecological stress, forming a povertyenvironment trap. This study argues that protecting the Sundarbans environmental integrity and enhancing its carbon sequestration potential are inseparable from improving human well-being. Achieving Indias net-zero target by 2070 requires policies that expand clean energy access, build human capabilities and ensure justice for communities who contribute least to emissions but suffer the most from climate disruption. Implications: This study emphasizes the urgent need to integrate poverty alleviation with environmental sustainability in climate-vulnerable regions like the Indian Sundarbans. Rural poverty contributes to environmental degradation by increasing dependence on forest resources, leading to unsustainable practices and higher CO? emissions. Low education levels, limited livelihood opportunities and inadequate infrastructure intensify both poverty and ecological stress. To tackle environmental degradation, it is essential to implement conservation efforts alongside interventions that improve education, enhance connectivity, diversify livelihoods and strengthen social protection. Aligning environmental justice with rural development can break the cycle of poverty and ecological damage, promoting long-term resilience and sustainability. 2025 Air & Waste Management Association. -
Tracing Fe K X-Ray Reverberation Lag in the Energy-resolved Spectra of Narrow-line Seyfert 1 Galaxy Ton S180
We report the Fe K relativistic reverberation feature for the first time in the narrow-line Seyfert 1 galaxy Ton S180. Using a long observation from XMM-Newton we find that the Fe K emission lag peaks at 117 49 s in the lag energy spectrum computed for frequencies (0.3-8.5) 10?4 Hz. The lag amplitude drops to 22.85 14.20 s as the frequency increases to (8.5-30) 10?4 Hz. The time-averaged spectrum of the source shows a relatively narrow Fe K line at ?6.4 keV, indicating a low black hole spin ( a = 0 . 4 3 ? 0.14 + 0.10 ) based on the reflection modeling. We perform general relativistic transfer function modeling of the lag energy spectra individually. This provides an independent timing-based measure of the spin at a = 0.3 0 ? 0.17 + 0.34 , a black hole mass M BH = 0.2 9 ? 0.16 + 0.01 1 0 8 M ? , comparable to the previous measurement, and a coronal height h = 2.5 9 ? 0.33 + 5.17 r g . Further, we observe that the Fe K lag and the black hole mass fit well in the linear lag-mass relation shown by other Seyfert 1 galaxies. 2026. The Author(s).

She Shores A Study on the Lives, Challenges and Resilience of Women of the Koli Fishing Community in Mumbai
This study delves into the lives of women from the Koli fishing community in Mumbai, aiming to illuminate their unique life experiences and the daily struggles that often remain hidden beneath their prosperous facade. It endeavours to examine their agency and adaptive strategies employed to navigate these challenges. The research was conducted in Pachubandar, Vasai, located in the western suburbs of Mumbai, which stands as one of the prominent Koli settlements in the city. Employing a qualitative research approach coupled with an exploratory research design, the study engaged ten participants, comprising seven Koli women and three key informants from the community. Additionally, an observational analysis of four retail and wholesale fish markets in Mumbai was conducted to gain insight into the working conditions of Koli fisherwomen. This study adopts a gender-focused perspective to scrutinise the contextual vulnerabilities that shape the lives of Koli women. It underscores the paradox wherein, despite playing a pivotal role in sustaining both their families and the traditional fishing occupation, their contributions often go unnoticed. The Koli women face severe deprivation due to their limited access to property and decision-making authority. They find themselves entangled within traditional norms and patriarchal structures, which impede their access to essential assets and diverse livelihood resources. Although they significantly contribute to the fishery sector, their struggles, needs, and aspirations are frequently disregarded due to their lack of representation and involvement in decision-making bodies. The majority of these women work under precarious conditions, devoid of proper infrastructure, resources, and security. Furthermore, the evolving dynamics within the fishery sector, driven by rapid urbanisation and modernisation, have a profound impact on the lives and traditional livelihoods of Koli women. They now confront issues such as dwindling fish catches due to environmental degradation, heightened market competition, reduced livelihood spaces brought about by shifting urban and coastal landscapes, altered labour relations, and technological advancements. Consequently, they find themselves caught between the conflicting forces of tradition and modernity. The research also sheds light on the strategies devised by Koli women to resist and adapt to the uncertainties and challenges they encounter, ultimately safeguarding their livelihoods through self-organisation. The study emphasises the imperative to acknowledge their contributions as visible work and advocates for the incorporation of gender considerations when formulating policies and development strategies within the fisheries sector.

Analysing the Effectiveness of Solana Blockchain Platform and PoH Consensus Algorithm in Providing a Solution for Blockchain Scalability Problem
Solana started its journey in April 2018 and is now a public blockchain - based platform which aspires better scalability than other existing blockchains while providing security and decentralization. It backs the development of decentralized applications and smart contracts (DApps). The goal of the study is to confirm several of its characteristics, like its transaction throughput, or the pace in which legitimate transactions are committed to a Solana network block over the course of a one-second period (TPS). A secondary dataset that was gathered over the course of 60 days and made available on GitHub was utilized. Our data analysis findings demonstrate that the transaction throughput on an average is about 3006 TPS at a much lower transaction fees than the fees users pay for many other blockchains that facilitate the same operations, such as use of smart contracts and the development of DApps. The document explains the workings of the Solana blockchain, which, in the words of its creators, claims to address the scalability issue without compromising security and decentralization.

Effective on-site waste minimisation approaches in Indian construction projects
Indias rapidly expanding construction sector generates substantial material waste, creating environmental and economic challenges that are often intensified by weak on-site waste management (WM) practices. This study investigates effective approaches for minimising material waste in building construction projects using a mixed-methods research design. The research integrates a systematic literature review, expert interviews, and a large-scale questionnaire survey to identify and prioritise waste minimisation strategies. From an initial set of 38 practices, 15 key strategies were shortlisted through descriptive and inferential statistical analysis. Their practical effectiveness was then evaluated through longitudinal monitoring of material waste across seven construction stages at four active residential sites. The results indicate a consistent reduction in material wastage following the implementation of targeted interventions. By triangulating expert insights, industry perceptions, and empirical site-based evidence, this study moves beyond perception-based assessments and provides empirical validation of waste minimisation strategies under real construction conditions in a developing-country context. The findings demonstrate that sustained waste reduction depends on an integrated approach combining human behaviour, managerial control, and proactive planning from early project stages. The study offers practical guidance for improving material efficiency, reducing costs, and advancing sustainable construction practices in India.
