Development of Green Synthesized Novel Carbon Dots from Ruta Graveolens L. for Fluorescent and Intracellular Sensing of Mercury Ions in Pico-molar (pm) Concentration
Green nanotechnology, which uses carbon nanomaterials for environmental remediation, is the pioneer among the prevailing approaches for the production and characterization. In the present study, highly fluorescent carbon dots (CDs) from Ruta Graveolens (ARH-CD) is developed, and its efficacy as a fluorescent sensor and biomarker is investigated. They act as a fluorescence sensor for Hg2+ over an extensive concentration range of 1 picomolar (pm) to 1 molar (m), with a detection limit as low as 26.75 pm. The studies reveal ARH-CD as an effective biomarker for intracellular toxicity analysis and a fluorescent probe for multi-colored (blue, green, and red) imaging of HEK293 cell lines. After 24 h of incubation, it is found that the ARH material reveals noticeable biocompatibility and visible fluorescence, with a viability of 98.88% at 5 gmL?1 and over 78.33% even at a concentration of 100 gmL?1. The IC50 value for the MTT assay for cell viability results is calculated to be 224.56 4.67 g, which further confirms the appreciable biocompatibility of the ARH-CD. The obtained samples are effective in being inspected for the intracellular detection of Hg2+ and serve as a possible candidate for cell imaging. 2024 Wiley-VCH GmbH. -
Green Synthesis of Nano Carbon-Infused Polymer for The Detection of Toxic Heavy Metals
The global population is marching towards greener ways of life. Green nanotechnology, newlinewhich uses carbon nanomaterials for environmental remediation, is the pioneer among the existing strategies for the production, characterization, and applications of carbon nanomaterials derived from sustainable and renewable energy resources. Additionally, easily available natural ingredients are effective carbon precursors for producing carbon dots with newlineenthralling physical and chemical properties. Compared to other approaches, plant-based newlinesynthesis of nanomaterials is more dependable because it is simple, fast, ecologically newlinefriendly, and does not require particular conditions. We report for the first time, the use of a fluorescent nanocarbon material synthesised from plant, Indigofera Tinctora (L.) (IBLH), for the detection of metal ions. This nanomaterial developed using a green synthesis method that aided hydrothermal processing from the leaf extract of IBLH. The IBLH sensor used to detect hazardous metal ions (Pb2+) was very sensitive and selective. Considering the concentration from 1 nM to 100 mM and 100 mM to 1M, developed sensor displayed broad, dual linearity. The limit of detection (LOD) for the sensor appreciable low with 14.74 nM as the detection limit, with a wide and linear response spanning from 1 nM to 1M Cd2+ concentration range. Utilising Ruta Graveolens as the carbon source, we developed ARH-CDs from agricultural waste using chemical-free, one-step hydrothermal procedures that are safe for the environment. The synthesized ARH-CDs showed nano particle size, outstanding water newlinesolubility, great biocompatibility, and appreciable optical characteristics. The FTIR and XPS findings validated the existence of functional groups. such as C-O, C-C, and O-H with various oxygen functional groups, with predominating hydroxyl group, supporting the newlineexistence of CDs. For the selective detection of Hg2+, the synthesized ARH-CDs are employed as a biocompatible fluorescence sensor. -

Curiosity in calamity: How personal schadenfreude shapes disaster-tourism intentions
Tourism to sites of recent disaster, a form of dark tourism has raised questions about whether visitors are driven by typical travel motivations or by morbid impulses. This study examines how conventional tourist motives and the personality trait of benign schadenfreude (pleasure at others misfortune) jointly influence peoples intentions to visit a recent disaster site. By surveying 438 tourists to Kerala, four months after the July 2024 Wayanad landslides, we measured four common travel motives (novelty seeking, fun/entertainment, knowledge/learning, and relationship bonding) alongside a benign schadenfreude scale and visit intention. Partial least squares structural equation modelling (PLS-SEM) was employed for modeling. The model explained 58.80 percent of the variance in visit intention. Three motives viz., novelty, knowledge, and relationship had significant positive associations with intention, whereas the fun motive showed a negative effect. Schadenfreude emerged as the strongest predictor of disaster-site visit intention. Moreover, schadenfreude significantly moderated the influence of novelty seeking: respondents high in schadenfreude exhibited especially strong curiosity-driven intent to visit. These findings suggest that interest in post-disaster tourism often stems from ordinary travel drivers (curiosity, learning, social bonding), but a disposition to enjoy others misfortune can intensify the appeal when novel experiences are involved. The research highlights the need for ethical considerations to be followed by the destination managers and authorities in managing dark tourism destinations. Key limitations include the use of a cross-sectional data, region-specific sample and the focus on benign dimension (versus malicious) of schadenfreude. Future research should validate these results in other cultural and disaster contexts, establish causal relationships, and examine additional personal factors as well as dimensions of schadenfreude. 2026 Joseph et al. -
Alcohol and social drinking norms as a catalyst between tourist motivation and tourist satisfaction
This article aims to understand the influence of alcohol availability, ethnicity, anti-alcohol enforcement at tourist destinations, social norms of drinking among tourists and relationships with tourist motivation and tourist satisfaction. A cross-cultural empirical study was conducted using purposive sampling of 476 tourists with partial least squaresstructural equation modelling (PLS-SEM). The results suggest that tourists perceive social norms of drinking and the availability of alcohol at destinations, when coupled with ethnicity, influence the dynamics of the relationship between tourist motivation and tourist satisfaction. The availability of alcohol at tourist destinations alone does not have any relationship either with tourist motivation or with tourist satisfaction. Based on the findings, tourist service providers and facilitators can design drinkscapes specifically based on tourists ethnic background and social norms of drinking to rejuvenate tourist destinations and make them more attractive and inclusive. As the current research considers the tourists ethnic background from a general perspective, future research may investigate the impact of subcultures to understand how ethnicity effects drinkscapes and tourist behaviours. 2025 Informa UK Limited, trading as Taylor & Francis Group. -
Revisiting the PushPull Tourist Motivation Model: A Theoretical and Empirical Justification for a ReflectiveFormative Structure
This study introduces a novel reflectiveformative hierarchical model specification for the classic pushpull tourist motivation construct, aligning its measurement with the theoretical distinction between intrinsic push drives and external pull attributes. Unlike the traditional reflective-reflective structuring of tourist motivation we defied the higher order factors (novelty, knowledge and facilities as formative. Using partial least squares structural equation modeling (PLS-SEM) on a purposive sample of 319 international tourists, we empirically validate the reflectiveformative (reflective first-order, formative second-order) model. The reflectiveformative model showed a superior fit and predictive power: it explained substantially more variance in key outcome constructs (social motives (R2 = 53.60) and self-actualization (R2 = 23.10)) than the traditional reflectivereflective specification (social motives (R2 = 49.30) and self-actualization (R2 = 21.70)), which is consistent with best-practice guidelines for theoretically grounded models. In contrast, the incorrectly specified reflectivereflective model showed stronger effects between unrelated constructs, supporting concerns that choosing the wrong type of measurement model can lead to incorrect conclusions. By reconciling the pushpull theory with measurement design, this works main contributions are a theoretically justified reflectiveformative model for tourist motivation, and evidence of its empirical benefits. These findings highlight a methodological innovation in motivation modeling and underscore that modeling pushpull motives formatively yields more accurate insights for theory and practice. 2025 by the authors. -
A novel discrete slash family of distributions with application to epidemiology informatics data
This study puts forward a new class of discrete distribution that can be used by the epidemiologists and medical scientists to model data relating to epidemiology informatics. The proposed distribution is superior to traditional discrete modeling alternatives, viz., discrete Weibull and geometric distributions in terms of its model fit and flexibility to handle heavy-tailed dataset. It is a flexible three-parameter discrete distribution, grounded in the slash family and can be considered as a refined extension to the geometric distribution. We explored the diverse properties of this novel distribution thoroughly by evaluating the mathematical properties. The models parameters are estimated using the maximum likelihood estimation method, where the methodology validity is confirmed through an extensive simulation study. Furthermore, the practical utility of the distribution to model epidemiology informatics was examined with the help of eight different datasets representing three different dimensions of the epidemiology informatics, viz., mortality, infection and medication statistics.

Effect of personality psychological capital institutional support on job satisfaction and affective commitment among private school teachers in south karnataka
A teacher's personality traits are important to create and maintain a classroom learning environment. The behaviour of Teachers depends on the characteristics of the personality. There have been many pieces of research based on the positive aspects of teachers' behaviour through enhancing some psychological states which are based on the positive institutional behaviour. This particular research has its focus on the positive strengths of the teachers, and this construct has an essential influence on job satisfaction. Hence, a satisfied and engaged teacher is very much necessary to strengthen the competitive student base of every School. To explore the fact, the researcher has chosen the constructs such as Personality, Positive psychological capital, Institutional factors (Perceived Institutional support, Work-life policies, Work autonomy), Job satisfaction factors, and Affective commitment to study the impact of the Big five dimensions of personality on job satisfaction and affective commitment of private school teachers in South Karnataka and to investigate the impact of psychological capital on job satisfaction and affective commitment of teachers. The study also attempts to understand the influence of Institutional factors (perceived Institutional support, work-life policies, and work autonomy) on job satisfaction and affective commitment. Also, the study explores the influence of job satisfaction on the outcome factors namely affective commitment among private school teachers. The study used a descriptive research design, and it is observed that the total number of districts in south Karnataka is fifteen. The researcher selected four private schools from each district randomly with the help of the private school list used as a sampling frame. The total sample size for the study estimated were 477 teachers working in private schools. The study has analysed the data using appropriate statistical tools such as (i) frequency analysis, (ii) Factor analysis, (iii) ANOVA with post hoc (v) Regression analysis. The study concludes that when the private school teachers personalities such as extraversion, agreeableness, conscientiousness, and openness to experience which will tend to significantly influence Job satisfaction among teachers working in the private schools of South Karnataka. Similarly, private school teachers Psychological capital like resilience, self-efficacy, optimism, and hope which tend to influence job satisfaction at their work significantly. This study also concludes that private school teachers to be given proper work-life balance and work autonomy by the school management, which will significantly influence job satisfaction among the teachers at work. Also, private school teachers who possess personalities such as extraversion, agreeableness, conscientiousness, and openness to experience significantly influence the teacher's affective commitment. The study also reveals that the private school teachers have Psychological capital like resilience, Self-efficacy, Hope, and Optimism, which tend to significantly influence their affective commitment which will reflect towards their respective institution. If the private institution gave the school teachers proper work-life balance and work autonomy, then they tend to influence their affective commitment significantly. Also, it is concluded that the affective commitment of teachers significantly influences the job satisfaction level of school teachers. This implies that the school management can enhance the level of teachers' commitment to their schools by creating a more conducive and more satisfying environment in the workplace. Accordingly, schools can decide on pay and other monetary incentives. However, they can enhance teachers' job satisfaction by creating better training and development opportunities, improving leadership and management support, promoting accountability, and involving teachers in decision-making made at the school level. Another important finding of this study is the observed positive relationships between scores of job satisfaction and organizational commitment. Some of these findings contradict the existing literature in these fields; others are inconsistent with the prevailing literature. -

Globalization, Transnational Actors, and Questions on State Sovereignty: Prospects and Challenges
The two consecutive world wars and the subsequent economic recession significantly challenged the global socioeconomic and political landscape. The postwar society thus concentrated on improving economic growth. To energize this inspirational project, the globe promoted the widespread development of transnational actors. They include international institutions such as the UN, multinational and transnational corporations, Nongovernmental Organizations, and private actors. They are supposed to prioritize human rights, human security, and sustainable development. However, experiences affirm that they prioritize profit over protection and personal gains over sustainability. Furthermore, the unnecessary involvement of international organizations and corporations from developed countries in the affairs of developing countries creates complications and confusion regarding state sovereignty. From this perspective, this chapter uses qualitative methodology's analytical and critical methods to examine and evaluate the impact of globalization and transnational actors on state sovereignty. 2026 by IGI Global Scientific Publishing.

Cybercrimes in Bharatiya Nyaya Sanhita: A Critical Study on Indian Legal Scenario
Cybersecurity is a significant concern in the present digital world. The increase in cybercrimes attracts attention of the whole globe. India is one of the top countries on the list of cybercrimes and cyberattacks. More than 1 billion people use smartphones in India and the focus on digital economy has also attracted many cyberattacks. This necessitates the need for a specific legal framework. Indias Penal Code was almost 160 years old, and its provisions were not adequate to address the growing nature of cybercrime. Though the provisions of Information Technology Act, 2000 can be applied, India needed a criminal code addressing the latest trends of crimes. Many considered that the enactment of Bharatiya Nyaya Sanhita (BNS) will provide this required framework. In making a critical analysis the chapter tries to evaluate the provisions of BNS to examine whether it provided due protection to Indias cyberspace. 2026 by IGI Global Scientific Publishing.

Green industrialization for the sustainable future of developing countries: A critical study
The 2015 United Nations conference on sustainable development advanced seventeen Sustainable Development Goals (SDGs) that are essential for a sustainable future. Most of these goals either directly or indirectly affirm the importance of environmental protection. They also emphasize the need for social and economic sustainability. The various UN conferences stated that sustainable development has three essential elements such as economic, social and environmental sustainability and they are interconnected. Economic sustainability is achievable only through economic growth and the developed counties are in that high position. But the developing countries are still trying to make a potential stand. In the absence of economic growth, social inequalities are predominant in the Global South. Besides, they also face severe environmental insecurities. In order to achieve all these essentials, green industrialization was suggested. In this perspective, this chapter critically analyzes the feasibility of green industrialization to achieve sustainable future for the developing countries. 2025, IGI Global Scientific Publishing.

Persons With Disabilities: A Critical Analysis of India's Right-Based Approach
Disability is a challenging issue across the globe, as almost 16% of the global population has some kind of disability. India, the most populous country in the world, also faces the severity of disability issues as 2.2% of its population belongs to that group. For a good period, Indian society considered disability as a curse in the context of karma theory. Accordingly, the disabled faced discrimination, marginalization, and social exclusion. Though the Constitution guaranteed equal rights, India's approach towards disabled was mostly based on charitable contributions for their rehabilitation rather than a rights-based approach. But in line with the paradigm shift in the global approach, the Indian perspective also changed, underlining the rights of the disabled. Many policies were designed to give them access to the mainstream of the society, but India lacks adequate strategies for implementing these policies. 2026 by IGI Global Scientific Publishing.

Local self-government in India: A critical analysis through the lens of democratic decentralization
Local Self-Government (LSG) existed in a variety of forms throughout India. LSG was seen as an effective form of day-to-day management and administration in rural areas in India. This ensured a democratic form of administration even during the time of monarchs. Although it had a setback during the Muslim and British rulers period, it continued to exist. Gandhi raised his voice for increased decentralization and self-rule of the villages. Although the Constitution did not provide such an option, many committees opined that the local governance should be entrusted to the local people. Accordingly, LSG got constitutional recognition through the 73rd and 74th Amendments in 1992. It provided a three-tier system of governance at the regional level as well. Using analytical and critical lenses, this chapter examines the functioning of the constitutionally established LSG model through the lens of democratic decentralization to expose how far it has achieved its objective. 2026 by IGI Global Scientific Publishing.
