White LED Light-Mediated Eosin Y-Photocatalyzed One-Pot Synthesis of Novel 1,2,4-Triazol-3-Amines By Sequential Addition
Abstract: A facile and proficient, eco-friendly multicomponent synthesis of 12 novel biologically essential 1,2,4-triazol-3-amines via the sequential addition of substituted phenacyl bromide, aromatic aldehyde, hydrazinecarbothioamide, and urea under white LED with eosin Y as a photocatalyst has been developed. The intrinsic advantages are methodology is cost-effective, non-toxic, generates a high yield of product, is column chromatography free and does not need the use of a specific instrument. Surprisingly, our methodology uses moderate conditions and can count the tolerance of a wide variety of electron-donating and electron-withdrawing groups. The analysis and early conclusions give more value and context for the future development of organic synthesis using photocatalysts.

White Light Emission from Dy3+-Activated CaY2O4 Phosphor
Synthesis and characterization of a Dy3+-activated calcium yttrium oxide (CaY2O4) phosphor are reported. The CaY2O4:Dy3+ (1.5 mol%) phosphor is synthesized using a modified solid-state reaction technique for calcination and sintering. The cubic structure is revealed by the X-ray diffraction technique. The morphology and particle size distribution of the prepared phosphor are investigated by the FEGSEM technique. The chemical bonds and functional group analysis are confirmed by the FTIR. A photoluminescence analysis of the CaY2O4:Dy3+ phosphor shows dual excitation wavelengths at 285 and 348 nm, especially in the ultraviolet region. At 383 nm, three distinct emission peaks are found at the wavelengths 238, 485, and 571 nm. The spectroscopic parameters are calculated using the CIE chromaticity coordinates. The CIE coordinates of the Dysprosium ion-activated CaY2O4 phosphor (1.5 mol%) show an emission near the white light region of the chromaticity diagram, suggesting that it is suitable for W-LED applications.

Who mourns for her? The death and Re-death of Yakshi
In the Indian cultural lexicon, the term Yakshi refers to an enigmatic supernatural entity whose disposition can oscillate between benign and malevolent. This duality underscores the ambiguity and complexity inherent in traditional Indian narratives concerning gender and paranormal beings. In regional narratives from the southern state of Kerala, Yakshi embodies both demonic and divine essence. This phenomenon reflects a complex interaction between cultural beliefs, supernatural lore, and practices aimed at controlling or neutralising perceived threats from beyond the human realm. This paper focuses on investigating and delineating the progression leading to the death of Yakshi and analysing the subsequent integration into the natural environment. By examining literary/cultural narratives alongside gender and environmental symbolism, this study seeks to understand the transformation of Yakshi from a mythical figure to an intrinsic part of nature, particularly in the ambiguities surrounding Yakshis death, burial and mourning. 2026 Informa UK Limited, trading as Taylor & Francis Group. -
Why haven't you bought a solar panel? Consumerism at its "Green" best with the Myers-Briggs type indicator
This research study examined the relationships between Myers-Briggs' four personality dimensions and environmentally conscious consumption patterns. The study found that different personality types have different green purchase habits. The authors also propose five strategies for businesses who plan to venture into sustainable consumption. These strategies include leveraging the power of belongingness, forming addictive healthy habits, capitalizing on the domino effect, communicating with either the heart or the head, and prioritizing having experiences above owning things. The study's findings suggest that businesses need to take a more holistic approach to promoting sustainable consumption. Authors use discriminant analysis to evaluate whether each Myers-Briggs personality type had a distinct green purchase habit. For each of the four dichotomies associated with five kinds of green buying behaviors, SPSS was used to construct discriminant analysis indicators and outputs. 2023, IGI Global.

Why is the size of discouraged labour force increasing in India?
The Indian economy is currently passing through a critical phase of economic development as its structural transformation in employment has stalled, whilst both the youth unemployment rate and the number of youths Not in Employment, Education, and Training (NEET) have increased to an unprecedentedly high level. In the context in which the share of the youth population is continuing to rise despite the declining fertility rate to below the replacement rate, increased educated youth unemployment has caused an upsurge in the Discouraged Labour Force (DLF). This paper explores the trends, composition, and determinants of rising DLF in India using national level employment-unemployment surveys and macro-level panel data. Based on Multinomial logit and System GMM regression results, it is argued that policies aiming to enhance human capabilities through an improved base of technical education and the promotion of industry are necessary to enhance the growth of quality jobs in order to combat the problem of rising educated youth unemployment and DLF. Moreover, these measures could help in the process of harnessing the demographic dividend in India through an increased level of labour productivity in the long run. 2023, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature. -
Why learning space matters: a script approach to the phenomena of learning in the emergency remote learning scenario
The study focuses on how the notion of learning space is perceived and experienced by learners in the Emergency Remote Learning (ERL) scenario. In doing so, the lived experiences of remote learners who were abruptly shifted to a completely online learning space due to the pandemic COVID-19 in the Indian higher education system are documented. Online interviews were conducted with eight undergraduate and four postgraduate students of English and Cultural Studies, enrolled at a Southern Indian university, and their responses were explicated using the Interpretive Phenomenological Analysis (IPA) approach. The interviews revealed that the phenomenon of ERL is shaped by dissonance informed by the absence of a familiar learning space. Often the patterns of this dissonance were marked by (1) the perception of learning and learning space, (2) the lack of intimacy in learning and learning space, (3) the negotiations made for learning and the space of learning in ERL, and (4) the challenges to cope with the responsibilities of the ERL scenario. Further, the script approach was applied to analyse the data and the analysis revealed an expansion of the existing internal scripts that were based on previous learning experiences of the learners. The study thus establishes the centrality of space in the process of learning and points out how the lack of a familiar learning space is linked to the absence of internal scripts that considerably impact learning. The study concludes by discussing the possibilities of application of script approach to effectively incorporate the aspect of learning space in new pedagogies and learning models as Blended Learning (BL) and Online Learning (OL) become the new normal worldwide. 2021, Beijing Normal University. -
Why should businesses care about the metaverse
The fourth wave of computer innovation is now being driven by virtual reality (VR) and augmented reality (AR), two spatial, immersive technologies. The resulting pervasive computing paradigm, which this wave is expected to produce, can change (online) commerce, entertainment, distant employment, and education. This new paradigm is called the Metaverse. Although the metaverse is still in its infancy, history demonstrates how swiftly new technology can advance, potentially leaving those who lag. Digital reality technologies can transform the entertainment industry, remote work, education, marketing, and economics. Additionally, these technologies are starting to create a new paradigm for information exchange. The concept of the Metaverse has given rise to a new paradigm. While it appears that it will take years for the metaverse to reach its full potential, it is currently a phenomenon marked by the activity of hundreds of entrepreneurs who are making noise but producing no noteworthy results. According to many observers, the current uptick in activity by large tech businesses is assisting in bringing some order to the market's volatility by providing startup companies with the dependable mainstream customer bases they lack. In order to provide better and more integrated business processes, metaverse will provide a far more immersive experience to an organization's whole ecosystem of clients, staff, and partners. In light of this, the study's objectives are to comprehend the business prospects in the metaverse, identify relevant business strategies, and forecast future business developments in the metaverse. The study also looks at the challenges that companies have while integrating the metaverse, taking into account different scenarios. 2024, IGI Global. All rights reserved. -

Will the antioxidant supplements impact the mitigation of oxidative stress in Parkinsons disease?
Parkinsons disease is a frequent neurodegenerative condition marked by both non-motor and motor symptoms. It is brought on by the selective depletion of dopamine neurons from the substantia nigra region of the midbrain. Numerous variables, including lifestyle, environment, age, smoking, and underlying medical disorders, affect the occurrence of Parkinsons disease. The free radicals created by oxidative stress have an impact on the morphology and function of neuronal cells and are a factor in many neurodegenerative disorders, including Parkinsons and Alzheimers, disorder. Although the pathophysiological mechanism causing neuronal degeneration is still unknown, oxidative stress plays a critical role in the pathogenesis of idiopathic Parkinsons disease. It also has an association with numerous proteins, including ?-synuclein, amyloid, DJ-1 protein and several signalling pathways like extracellular regulated protein kinases. Reactive oxygen species also contribute to complex Is mitochondrial respiratory activity. The naturally occurring antioxidants are the phenols, anthocyanins, carotenoids, flavonoids, vitamins, and lignans. These antioxidants retain the reactive oxygen species generation and plays a role in several biological effects. As a result, natural plant antioxidants may have an impact on Parkinsons disease and offer an alternative therapy that minimises oxidative stress and slows down the evolution of the disease. 2024 Visagaa Publishing House. -
Will Users Continue Using Banking Chatbots? The Moderating Role of Perceived Risk
AI-powered chatbots have become game-changers for the financial industry. They enable banks to boost customer engagement and improve operational efficiency by lowering the traditional cost of customer support. This study analyses the impact of perceived service quality dimensions on user confirmation, satisfaction and use continuance. The present study also analyses the moderating effect of perceived risk on the relationship between user confirmation, satisfaction and chatbots use continuance. A total of 447 customers, all residing in the Indian city of Bengaluru and having recently used banking chatbot services, were surveyed. Partial least squares structural equation modelling is used to examine the relationships between the variables used in the study. Findings from the study show that all five chatbot service quality dimensions (reliability, interactivity, assurance, responsiveness and understandability) significantly impact the users post-use confirmation, influencing their satisfaction and continuance behaviour. Perceived risk negatively moderates the relationship between user confirmation and user satisfaction. Chatbot service developers and e-service providers can leverage these findings to understand user expectations from chatbots. They will also be helpful to other service sectors, such as insurance, travel and tourism, hospitality and healthcare. 2023 Fortune Institute of International Business. -
Winning battles with a joke: a qualitative inquiry of humour in the Indian Army
Humour in military organizations can be antithetical given the rigid hierarchy, high degrees of work formalization, and obedience to hierarchy. This paper explores how humour is initiated, propagated and maintained in the Indian Army. We conducted twelve in-depth interviews with retired army professionals and used Braun and Clarkes (2006) thematic analysis to capture the study's main findings. Three major themes emerged organizational humour, leader humour, and team humour. We found humour is essential in combating stress, increasing social cohesion, facilitating newcomer assimilation, and promoting a positive work environment. We also found evidence of subversive humour used in forms of resistance to challenge the hierarchical structure subtly. We have provided a three-part schema of workplace humour which sheds interesting insights on workplace humour. Our findings will contribute to understanding how military humour helps to maneuver challenges of a stressful work situation 2023,European Journal of Humour Research. All Rights Reserved. -
Wired Highways: The Soul of a Smarter City
The "smart city"concept emerged in the 1990s, characterized by extensive globalization, rapid technological advancement, and the emergence of the knowledge economy. Urban planning professionals began considering how to introduce digital technology into existing city infrastructure to create cities that were faster, efficient, sustainable, and better managed. Innovative thinking has moved away from traditional methods of city planning and management, and has started to challenge the planning systems where governments understood complexity from a bureaucratic perspective. In planning smart cities, local governments are largely relying on using information and communication technologies (ICT) to enhance essential city functions like transportation, energy, water, and public safety. Urbanization is becoming increasingly complex, and the global urban population is growing at unprecedented rates, creating a need of urban systems to be smarter, safer, and more environmentally sustainable. Cities are faced with many complex problems, but urban transportation is one of the most daunting. Existing infrastructure is becoming overwhelmed by congestion, increasing volume of traffic, and safety issues. An innovative way of tackling these problems is through Intelligent Transportation Systems (ITS). ITS is the use of ICT including sensors, software, communication networks, and data analytics in transportation systems to increase efficiency, safety, reliability, and sustainability. By using real-time monitoring, predictive analytics, and data-driven decision-making, ITS creates traffic management systems that improve city response time, decreases congestion and accidents, and increases sustainable or environmental-friendly transport choices. This research recognizes the importance of ITS to smart city development, emphasizing. 2026 IEEE. -
