Unofficial Bilingualism in English-Only Policy Context: A Postmethod Pedagogy for Difficult Circumstances in Rural Government Schools of Tamil Nadu
This chapter introduces and explains the phenomenon of Unofficial Bilingualism in government-run English-medium schools in rural Tamil Nadu, India. It delineates instances of using the mother tongue to navigate language learning challenges in schools with an official English-only policy. It studies three schools in the Salem district of Tamazil Nadu using a qualitative research framework, with classroom observation and telephonic interviews with teachers as primary research methods. Using thematic analysis of recorded classroom observation of three teachers use of L1 in the English classroom and in-depth, semi-structured telephone interviews with rural government schoolteachers across Tamil Nadu, the study grounds the phenomenon of Unofficial Bilingualism within the conceptual framework of Difficult Circumstances in ELT (West, 1960; Smith, 2011; Anderson, 2021) and explains it as a form of Postmethod Pedagogy (Kumaravadivelu, 2001, 2006). It explains the use of L1 in the classroom, despite official policy mandating teachers not to, and provides theoretical justification to legitimise the use of L1. The chapter argues for making Unofficial Bilingualism official and discusses its implications for classroom policy and teacher education, reconciling classroom practice with official policy. The study has implications for medium of instruction, language policy and teacher education. 2025 selection and editorial matter, Uma Pradhan and Mohini Gupta; individual chapters, the contributors. -
Assessing the socio-ecological effects of lakeside gentrificationA case study of two lakes in South India
The global push for sustainability and the urgency of addressing climate change have compelled city governments worldwide to prioritize the upkeep and restoration of urban commons. However, this state-led or private-driven greening often becomes a marker of gentrification. This study examines the ecological conservation policies applied to Periyakulam Lake in Coimbatore, Tamil Nadu, and Hebbal Lake in Bengaluru, Karnataka, aiming to elucidate how these policies exhibit flaws and lack inclusivity. Through the lens of urban political ecology, the research scrutinizes the state-led and state-supported strategies, emphasizing their tendency to favour a minuscule population while perpetuating aspects of gentrification. It critically examines the dual phases of lakeside gentrification, wherein the first phase involves the modification of the lake under the label of rejuvenation. The subsequent phase witnessed a transformation in the surrounding region's social, spatial, and economic characteristics as it became increasingly attractive and subject to investment. Such processes displace and dispossess livelihoods and instil a new urban imaginary where only urban elites become the standpoint for such beautification consumption. This study contributes to the literature on lakeside gentrification and argues how state-led and state-supported extractive policies remove the safety valves for a stable future by negating the linkages between society and nature. 2025 The Author(s) -
Education for All: How Schooling Is Creating Social Changes for Lowered-Caste Girls in Rural India
Arguments for the expansion of formal schooling have long focused on individual outcomes from schooling, including increasing income, reducing poverty, delaying marriage, and improving health, particularly for girls and women. For nearly three decades now, global education agendas have supported girls education in an effort to achieve these outcomes. A large body of research analyzes girls individual empowerment from schooling, but less attention is given to how schooling is creating change in families and communities, particularly for lowered-caste girls in India. This article places longitudinal data from a three-year qualitative interview study of schoolgirls in Rajasthan alongside qualitative life-history interviews of girls who completed secondary school in Uttarakhand to understand how schooling affects social changes for lower castes. The analysis, using an intersectional and relational approach, illustrates how girls schooling shifts kin and caste relations connected to marriage and work but in ways that do not transform the stickiness of caste and gender norms. We argue that educational policies and programs must attend to the ways in which caste is implicated in achieving outcomes of delayed marriage and formal employment for lowered-caste girls in Indian communities if schooling is to create positive social change. 2020 by The Author(s). -
A Narrative Synthesis on the Role of Affective Computing in Fostering Workplace Well-Being Using a Deep Learning Model
Emotional information is more valued in the modern workplaces with increased focus on the need for sensing, recognizing and responding to human emotions. Integrating human emotions as information for communication and decision-making is possible through the computer-based solution called as affective computing. Affective computing is a relatively less explored AI platform though the notion is more than two decades old. The cognitive algorithms employed in affective computing operates in three key areas, viz. context sensitivity, augmented reality, and proactiveness, with outcomes in the fields of emotion management, health, and productivity. Affective computing promises better management of organizational outcomes such as fostering workplace well-being, promoting happiness, productivity, engagement levels, and communication. Further, affective computing can play vital roles in an employees life cycle with applications in functional areas of HRM like employee selection, training and development, and performance management. Even as workplaces are increasingly adopting affective computing, an analysis of its positive effects can help practitioners take informed decisions about its implementation. This paper outlines the theoretical underpinnings of affective computing, discusses the relevance of ResNet50 in image analysis, and proposes a step-by-step methodology for implementing affective computing techniques in the workplace. The potential benefits and challenges of adopting affective computing in fostering workplace well-being are also discussed. Thus, this chapter investigates the role of affective computing in fostering well-being in the workplace usinga deep learning model.

Students Perceptions on the Generative AI Tool ChatGPT: Examining the Interrelationships Between Knowledge, Willingness and Challenges
Generative artificial intelligence (AI) tools are disruptive innovations of recent times that have tranformed numerous sectors, including education. In the realm of management education, platforms such as ChatGPT are redefining teaching methods, tailoring learning pathways and opening new research frontiers. This study examined MBA students perceptions of their knowledge, willingness to use and challenges encountered when engaging with generative AI tools, particularly ChatGPT considering differences by gender and by usage frequency. Through purposive sampling, responses were collected from 179 MBA students at management institutes in Bengaluru, Karnataka, via an online survey adapted from the validated questionnaire by Chan and Hu. Data analysis was conducted using SPSS version 26 for Windows. Bootstrapped univariate General Linear Models showed no gender-based disparities in students knowledge, willingness or perceived challenges; however, usage frequency of AI tools emerged as a strong predictor of willingness to adopt. Multiple regression results indicated that greater knowledge positively influenced both perceived challenges and willingness, while perceived challenges significantly affected willingness. A Sobel mediation test further demonstrated that challenges partially mediated the effect of knowledge on willingnesssuggesting that increased knowledge heightens awareness of potential challenges, which in turn shapes students willingness to embrace these tools. These outcomes offer actionable guidance for educators and decision-makers, highlighting the importance of enhancing AI literacy, minimizing barriers to adoption and providing inclusive, experiential learning environments to support the responsible and confident integration of generative AI in management education. 2026 XLRI Jamshedpur, School of Business Management & Human Resources -
Secure Authenticated Communication Via Digital Signature And Clear List In VANETs
Vehicular ad hoc network (VANET) plays a vital role in the intelligent transportation system(ITS), When a vehicle receives a message through network, the CRL (certificate revocation list) checking process will operate before certificate and signature verification. After successful authentication,a CRL list is created based on authentication. This CRL is used to verify whether a vehicle node can be permitted for communication in the VANET network. But when using CRL, a huge amount of storage space and checking time is needed. So we proposed a method without CRL list, but mentions a key management list to overcome large storage space and checking time even it reduce the access delay too. For the access permission we can do an authentication system based digital novel signature authentication(DNSA) for each vehicles in the vanet with the RSU unit or with other participant node vehicles in the communication as per the Topology.So we can perform an efficient and secured communication in VANET.

Reducing Systemic Bias in Behavioral Targeting Using Explainable AI: The HARMONIA Complex Systems Approach
Behavioral targeting is a key part of the modern advertising web's algorithmic engine. However, it is unclear whether optimization processes worsen bias, promote unchecked spread in filter bubbles or lower overall users' trust levels. This paper introduces HARMONIA (Holistic Adaptive Regulatory Model for Optimizing Non-transparent Intelligent Advertising), a comprehensive, data-driven Explainable Artificial Intelligence (XAI) framework aimed at transforming behavioral targeting via transparency, interpretability, and adaptive ethical regulation. This paper conducted a comprehensive Explorative Data Analysis (EDA) on the public Criteo Display Advertising Dataset, which contains over 45 million records, to identify patterns in high-dimensional user-ad interaction space. This analysis uncovered latent behavioral signals that affect the relevance of ads based on users' online behavior. The analysis identified four interrelated behavioral dynamics: ad fatigue attenuation, diurnal engagement oscillations, device-driven preference divergence, and category-affinity dominance. These dynamics served as the foundational architectural principles for HARMONIA's design. The method uses gradient boosted prediction models and a multilayer explainability stack that includes SHAP for global interpretability, LIME for local surrogate approximation, and counterfactual reasoning for causal transparency. Quantitative evaluation indicates that HARMONIA maintains relevance accuracy (approximately 1.2% CTR), achieves a 31% enhancement in transparency metrics, and a 27% improvement in user-trust indices, while concurrently reducing systemic entropy by nearly one-third. This research redefines personalization to be self-explanatory and ethically sound AI by incorporating explainability as a regulatory mechanism in the adaptive ecosystem of complex digital advertising. This system takes explainable computational marketing from an idea to a full-scale implementation. 2026 Binghamton University Libraries. All rights reserved. -
Impact of Social Media on Patience, Anxiety and Stress
Social media has become deeply integrated into everyday life, constantly connecting us to various platforms. While people were once believed to be shaped by those they spent time with physically, the content we consume and individuals we follow online now significantly influence our thoughts, emotions, and behaviours. Despite growing concerns about these effects, limited research has examined the relationship between social media usage patterns and psychological well-being among young adults. This study examined whether social media usage patterns affect patience, stress, and anxiety among young adults. A cross-sectional survey was conducted with 124 participants aged 18-30 years. The survey collected demographic information and assessed social media usage patterns, with scores computed for patience, anxiety, and stress. Results indicated that stress levels were positively correlated with social media usage (r=0.33, p< 0.001), with Instagram emerging as the most widely used platform. A paired t-test revealed that participants significantly underestimated their actual screen time compared to their perceived screen time, t(123) = [insert your t-value], p=0.0002. Correlation analysis also indicated that screen time was positively associated with increased anxiety (r=0.22, p=0.014) and negatively associated with patience (r=-0.19, p=0.035). These findings highlight the importance of developing digital self-awareness, encouraging individuals to maintain control over their social media usage rather than letting these platforms dictate their levels of stress, patience, and anxiety. 2025 IEEE. -

Unveiling the potential: iodide-infused nickel-enhanced MXene composite for high-performance sodium ion hybrid capacitors
2D-MXenes have gained much popularity for energy storage applications such as hybrid capacitors, and they have shown very competitive performance, especially as electrode materials for sodium ion hybrid capacitors. However, they suffer from various problems, such as morphology distortion and fast capacity fading, which results in the poor performance of the battery. As a result, researchers have focused more on MXene-based composite materials to address these issues. In this work, we report a sodium iodide and nickel-decorated MXene-based composite (Ti2C/Ni/NaI) material as an electrode for a sodium ion hybrid capacitor. Ti2C MXene and Ni were able to provide physical and mechanical strength, and iodine was able to produce redox activity. The composite had a rough surface with readily aggregated 2D-MXene sheets and was uniformly covered with Ni, Na, and I atoms. Several vibrational bands and peaks associated with Ti, Ni, Na, C and O in the Raman while XPS spectra confirmed the effective incorporation of dopants into the MXene sheets and successful synthesis of the Ti2C/Ni/NaI composite. The fabricated hybrid capacitor exhibited good capacity retention of 59% after 10,000 cycles at a current density of 0.5 mA g?1; thus, the Ti2C/Ni/NaI composite can be a promising electrode material for sodium-based hybrid capacitors. 2025 The Author(s).

Electrochemical sensor based on PVP coated cobalt ferrite/graphite/PANI nanocomposite for the detection of hydrazine
In this study, we developed a multi-layered electrode as an efficient nanocomposite electrochemical sensor for detecting carcinogenic hydrazine in water. Nano-cobalt ferrite (CoFe2O4) was prepared using poly (vinylpyrrolidone) (PVP), mixed with an optimum quantity of graphite and pasted on a stainless-steel current collector. The nanocomposite was further hybridised by electrodepositing with polyaniline (PANI). The obtained composite was characterized using XRD, FTIR, SEM, and electrochemical techniques. XRD analysis shows the successful formation of composite from individual precursors. According to SEM, wrinkled and layered morphology for graphite and aggregate clusters for cobalt with spike or tubular structure for polyaniline were observed. When subjected to amperometry current, the prepared electrode showed different peaks for different concentrations of hydrazine, such as 1 ?M to 100 ?M. Cyclic voltammetry studies showed an increase in oxidation and reduction peaks. These studies will lead to a new platform for their potential applications in detecting toxic materials in real samples such as water, plastic bottle, water etc., 2023 The Author(s).

A Revitalising Approach towards Aging: Unveiling the Potential Use of Probiotics for Wellness in Elderly Populations
Probiotics have emerged as a potential alternative for treating various diseases affecting general population. Mounting data suggests that probiotics can be beneficial for older individuals, who often have weakened immune systems and are more susceptible to illnesses. Dysbiosis commonly occurs in elderly individuals, which is implicated as a major reason for various diseases. The effectiveness of probiotics is influenced by the specific strain and the dosage administered. Extensive studies have shown how probiotics affect prevalent issues, such as functional bowel diseases and other gastrointestinal disorders. Probiotics exert their effects by synthesizing different microbial peptides, such as bacteriocins, antibiotics, lipopolysaccharides, short-chain fatty acids, butyric acid, propionic acid and other specific secretory metabolites. The common probiotics that are found to benefit the health of elderly populations include Lactobacillus, Bifidobacterium lactis, Bacillus subtilis, Bifidobacterium longum and Bifidobacterium breve Further research is necessary to delve into the mechanism of action for both existing and novel probiotic strains for use in combating or aiding in diseases. Genetically, modified probiotics can be potentially used in the future to deliver immunity-restoring genes and as oral mode of vaccination in humans. Fecal microbiota transplantation has been gaining interest, used to restore gut conditions, and has also been linked to alleviating neurodegenerative diseases. The focus of this review was to present the available evidence on the immunomodulatory effects of probiotics in the elderly population; aiming to gain a better understanding of their mechanism of action and to assess the progress made in utilizing probiotics as therapeutic interventions. 2023 JHSMR.
