Gamification in teacher education: Teacher educators and trainee teachers' perspectives in India
description: Gamification emerged as a teaching-learning pedagogy in recent years. Its usage increased during the Covid-19 lockdown and continued post-pandemic time. Its usage ranges from online to offline tools; teachers lack its awareness as a pedagogy. The present study aimed to understand perspectives of teacher educators and teacher trainees on inclusion of gamification pedagogical training in teacher preparation programmes. The study employed a mixed-method approach and included qual-quant sequential explanatory research design. Researchers conducted semi-structured interviews with six teacher educators and six trainee teachers and collected the opinion of 200 teacher educators and trainee teachers. The study employed inductive thematic analysis and Chi-square analysis for qualitative and quantitative data respectively. Findings revealed six main themes and twelve sub-themes. Chi-square revealed a gender science-stereotype amid association between teacher educators and teacher trainees' opinion. Senior teacher educators did not believe in the importance of gamification inclusion in teacher preparation. 2024, IGI Global. All rights reserved.

Gamification in Tourism Teaching and Learning: Exploring the Emergent Dimensions
subject: Challenges; Gamification; Learning; Teaching; Tourism; Tourism education
description: First introduced in 2002 by British Programmer Nick Pelling, the term gamification has gained massive momentum in the last decade with extensive applications in teaching and learning (Hebebci & Selahattin, Current Studies in Social Sciences 2021:174, 2021). In its simplest form, gamification refers to the adoption of principles and design elements of various games in nongame situations (Deterding et al. From game design elements to gamefulness: Defining gamification. In Proceedings of the 15th international academic MindTrek conference: Envisioning future media environments (pp. 915), 2011). Further, the interaction between the students and technological interventions is rising, opening new avenues for innovative strategies like gamification to promote effective teaching and learning (Kapp, The gamification of learning and instruction: Game-based methods and strategies for training and education. Wiley, 2012). In the context of tourism, works of (Nair, B. B. Endorsing gamification pedagogy as a helpful strategy to offset the COVID-19 induced disruptions in tourism education. Journal of Hospitality, Leisure, Sport & Tourism Education, 30, 100362, 2022.) and Aguiar-Castillo, Herndez-Lez, De SaPez, and Pez-JImez (Journal of Hospitality, Leisure, Sport & Tourism Education, 27, 100267. https://doi.org/10.1016/j.jhlste.2020.100267, 2020) provide insights into the various facets of gamification as a tool for teaching and learning. However, these works hardly address the emerging issues in adoption, implementation, and barriers that have been dealt with in this chapter. Against this backdrop, the first section of this paper ventures into the various implications of gamification in the field of tourism teaching and learning. Next, taking cues from significant land marking studies, this work lists the factors responsible for making gamification an effective teaching and learning tool in tourism. Lastly, attempts have been made to underline the elements that may pose challenge…

Gaming for the Planet: Exploring Belief, Motivation, and Behaviour in Climate-Conscious Play
description: The emergence of digital games as an impactful medium for engaging audience from diverse background and clime cannot be overemphasised in today's world of sophisticated technologies and high-end devices. This study explored the potential capabilities of digital games in influencing beliefs, motivations, and behaviours that have connections with climate. The main purpose was to understand the psychological and structural game design elements that promotes measurable ecological impact. Case studies from the EU-funded GREAT Project, such as Play2Act, and broader literature on gamification for environmental engagement. Data from a global in-game poll (n > 180,000) was analysed to gain insights into how green messaging within popular games translates into real-world behavioural changes. Findings from the study shows that 65% of players reported increased awareness of climate issues. Also, results indicated that 40% of the players adopted at least one new eco-friendly behaviour after gameplay. Finally, it was found that specific game design elements like reward systems and narrative integration. The study concluded that mainstream digital games could serve as scalable tools for environmental engagement, which can bridge the gap between environmental psychology, game studies, and design research. We recommend that future research should focus on refining these design frameworks and integrate them into policy to maximise the ecological impact of digital games. integration. 2025 IEEE.

Gamma irradiation effects in InBi0.8Te0.2 crystals grown by horizontal directional freezing
subject: Crystal growth; Dielectric properties; Hardness; Irradiation; Optical properties
description: The high-energy gamma-ray irradiation treatment using Co-60 isotope offers the possibility of engineering mechanical and optoelectronic properties of InBi0.8Te0.2 crystals. Tellurium-doped indium bismuthide (InBi) crystals were prepared by horizontal directional freezing technique. Dose-dependent modifications in structure, composition and surface topographical features have been analyzed by X-ray powder diffraction, X-ray energy-dispersive analysis, transmission electron and atomic force microscopy, respectively. Dielectric constant and dielectric loss were found to increase with the cumulative dose of radiation, and a shift in the ferroelectric transition temperature (T0c0) from 405 to 410 K was observed for 25 kGy. Upon irradiation, there is an enhancement in microhardness (H0V0), yield stress (sigma; 0y0) and stiffness constant (C0110). The optical transmittance was decreased by 12.45%, resulting in a reduction in the optical band gap from 0.210 eV to 0.198 eV. These results indicate the suitability of InBi00.80Sb00.20 crystals for low-wavelength infrared applications. The Chinese Society for Metals and Springer-Verlag Berlin Heidelberg 2015.

Gammaless gamma-ray bursts?
subject: Compactness problem; Gamma-ray bursts; Neutrinos
description: One of the possible resolutions of the compactness problem in gamma-ray bursts (GRBs) is by invoking the Lorentz factors associated with the relativistic bulk motion. This model applies to GRBs where sufficient energy is converted to accelerate the ejected matter to relativistic speeds. In some situations, this may not be a possible mechanism, and as a result, the gamma rays are trapped in the region. In this work, we look at such possible scenarios and where the neutrino pair production process can dominate. As a result, the neutrinos can escape freely. This could give rise to a scenario where the release of neutrinos precedes the gamma-ray emission that is much attenuated. This model can thus possibly explain why fewer GRBs are observed than what is expected. 2023, Indian Association for the Cultivation of Science.

GAN-Based Metaheuristic Techniques for Data Generation and Imbalance Data Control
description: In cybersecurity today, the power of features such as threat detection, anomaly spotting, and predictive analytics depends heavily on having abundant, properly dispersed datasets. The actual datasets often fall short, suffering both from a lack of volume and skewed class distribution, for example, a flood of routine network activity records overshadowing the infrequent but vital records of malicious behavior. The performance of data-driven models hinges on access to abundant, well-distributed data. However, real-world datasets frequently exhibit inadequate sample sizes and pronounced class imbalances, limiting the viability of complex models. This chapter proposes a novel strategy for generating synthetic data and effectively managing class imbalance, leveraging the integration of Generative Oppositional Networks (GANs) and sophisticated metaheuristic optimization techniques. Rather than settling for fixed GAN architectures, our approach progressively enhances a dynamic GAN framework by deploying a metaheuristic search to identify optimal network topologies, antidote scaling factors, and training schedules. This iterative calibration enables the model to adaptively respond to the imbalance and ensures a richer, balanced synthetic training environment. This adaptive optimization addresses common GAN training pitfalls, mode collapse, and instability while consistently producing synthetic samples that are both precise and varied. What sets the framework apart is its built-in ability to detect and over-represent minority classes, intelligently augmenting the dataset to correct class imbalance without falling back on naive duplication. By equipping GANs with metaheuristic reasoning, the study seeks to elevate data synthesis beyond current limits, generating more robust and impartial machine learning models in any domain where data collection is limited or systematically skewed. 2026 selection and editorial matter, E.

Gandhiji and RSS: The Cultural Grounding of Social Representations
subject: Congress; Culture; Gandhiji; Golwalkar; Hedgewar; Muslim League; RSS
description: Exploring the cordial relationship and mutual respect between Gandhiji and the Rashtriya Swayamsevak Sangh (RSS), this article critically examines the political rhetoric against the RSS and its implications. As a nationalist cultural organisation, the RSS had been well aligned with most of the social and cultural programmes initiated by Gandhiji. When critics of the RSS like Jawaharlal Nehru were keen on crushing the RSS, the truth-seeking political philosopher Gandhiji applauded its discipline, annihilation of untouchability and the rigorous simplicity. This article demonstrates how the serious charges against the RSS that were brought to the notice of Gandhiji by a section of Congress leaders further cemented the cultural grounding of social representations between the two, instead of making Gandhiji be the stranger of the RSS. 2023 ICHR.

Ganga and Yamuna Rivers: Through the Lens of the National Green Tribunal
subject: Ganga riverYamuna river; NGT Act; Water quality
description: Despite the country's extensive environmental jurisprudence and many historic rulings in which the courts have rescued worsening environmental situations, river (Ganga and Yamuna) water does not match the mandated minimum "bathing quality." Rivers like the Ganga and Yamuna, which flow through numerous states and towns, would be in a different situation. Without strict monitoring and enforcement of the measures, no action plan can work. Punishment of defaulters can serve as deterrence while also instilling fear in other non-compliant enterprises. In comparison to environmental legislation, the NGT Act allows for substantially harsher fines and penalties. River rejuvenation plans must be carefully monitored to ensure that they do not suffer the same fate. Making action plans will not improve river water quality unless they are implemented with sincerity and consistency, as well as continuous monitoring and severe enforcement. 2022 Technoscience Publications.

Garbage Management and Monitoring System Using IOT Applications
subject: Internet Protocol; Sensible Garbage Bin; Ultrasonic Sensors
description: The main purpose of this application, in addition to boosting the vision of a smart city, is to reduce humankinds effort and resources while simultaneously enhancing the vision. The squashing of the dustbin will occur on a regular schedule. It will be possible to manage waste more efficiently when these sensible garbage bins are implemented on a large scale and replace our previously designed dumpster, as it eliminates the need for waste to be piled up on the roadside in the first place. When managing the trash containers, wireless sensor systems in networks (WSN) in connection with the IoT technologies are used. On the other hand, sensors are used to monitor the container contents in real-time, with results displayed on the website, and the sensed contents are then evaluated to determine the optimal container distribution. This allows for the processing of a variety of waste types depending on the needs of the customer. As a result of installing ultrasonic sensors in each bin, garbage levels are continuously checked. As a result of this notification, the bin will be cleared. 2023, Bentham Books imprint.

Garcinia indica Leaf Extract Derived Ag-Zn Nanocomposites: A Sustainable Approach for Textile Dyes Photodegradation
subject: Chemical kinetics; Garcinia indica; Green synthesis; Nanocomposites; Photocatalytic; Reactive textile dyes
description: The recent advancements for the biosynthesis of nanoparticles from plant biomass offer a promising avenue for the sustainable and environmentally friendly production of nanomaterials. The utilization of plant extracts as bioreductants and capping agents leverages naturally occurring biomolecules for the controlled synthesis of nanoparticles, minimizing environmental impacts and promoting a more sustainable nanotechnology landscape. This study explores the biofabrication of silver-zinc nanocomposites (Ag-Zn NCs) using Garcinia indica leaf extract, offering a green and sustainable alternative to conventional methods. The synthesized nanocomposites were characterized using UV-vis, FTIR, XRD and TEM analyses. The UV-vis spectra confirmed the formation of nanocomposites with distinct surface plasmon resonance peaks (355 nm and 408 nm). FTIR identified functional groups involved in the bioreduction, while XRD indicated a crystalline size of 6.26 nm. TEM images revealed a mixture of hexagonal, spherical and rod-shaped nanocomposites with an average size of 40.37 nm. Furthermore, the study evaluated the photocatalytic activity of the Ag-Zn NCs against various reactive textile dyes (RY-86, RY-145, RB-220 and RB-222). Remarkably, the nanoparticles achieved an impressive 87-100% degradation of these dyes within 160-320 min under UV irradiation. This highlights the potential of biofabricated Ag-Zn NCs for environmental remediation, particularly in treating dye contaminated industrial effluents. This work demonstrates the feasibility of using G. indica leaf extract for the sustainable synthesis of Ag-Zn NCs with efficient dye degradation capabilities. 2024 Asian Publication Corporation.

Garlic peel based mesoporous carbon nanospheres for an effective removal of malachite green dye from aqueous solutions: Detailed isotherms and kinetics
subject: Adsorption studies; Biosorbents; Biowaste; Dye removal; Garlic peel; Malachite green; Nanoparticles
description: Biowaste based nanoadsorbents have gained much attention in the recent times for wastewater decolourization owing to their low cost, high surface area and high adsorption capacities. In the present research, garlic peel based nanoparticles (GCNP) were synthesized at different temperatures by a one step pyrolytic green approach for the effective removal of cationic dye, malachite green from the aqueous medium. The surface properties of Garlic nanoparticles were elucidated by N2 adsorption- desorption and all the GCNP samples were found to exhibit Type IV(a) isotherm indicating the presence of mesopores in carbon matrix. Using BET calculations, highest surface area (380 m2/g) was obtained for GCNP synthesized at 1000 ?C. Characterization of nanoparticles was done by XRD, EDAX, SEM and FTIR studies before and after the dye treatment. Adsorption studies conducted using different parameters like contact time, concentration and pH and dosage of adsorbent showed removal efficiency above 90% for the contact time of 70 min. Best adsorption experimental results were obtained for GCNP synthesized at 1000 C ascribable to its high surface area, higher total pore volume (0.26 cm2/g) and higher carbon content. Four adsorption isotherm models were used to validate batch equillibrium studies and the results showed data in good agreement with Langmuir and Freundlich isotherms with maximum Langmuir adsorbtion capactiy to be 373.7 mg/g. Kinetic modelling of the data showed best fit with the Pseudo second order model with rate constant value of 48.726 g mg?1 min?1. Regenerative studies were conducted conducted upto 6 cycles. Also the GC nanoparticles were tested for their compatibility in membrane form wherein, removal efficiency results were obtained for GCNP anchored in polyvinyl difluoride (PVDF) and polysulfone (PSF) membrane matrix for dye adsorption. 2022 Elsevier B.V.

Gas Kinematics and Dynamics of Carina Pillars: A Case Study of G287.76-0.87
description: We study the kinematics of a pillar, namely G287.76-0.87, using three rotational lines of 12CO(5-4), 12CO(8-7), 12CO(11-10), and a fine structure line of [O i] 63 ?m in southern Carina observed by SOFIA/GREAT. This pillar is irradiated by the associated massive star cluster Trumpler 16, which includes ? Carina. Our analysis shows that the relative velocity of the pillar with respect to this ionization source is small, ?1 km s?1, and the gas motion in the tail is more turbulent than in the head. We also performed analytical calculations to estimate the gas column density in local thermal equilibrium (LTE) conditions, which yields N CO as (?0.2-5) 1017 cm?2. We further constrain the gass physical properties in non-LTE conditions using RADEX. The non-LTE estimations result in n H 2 ? 10 5 cm ? 3 and N CO ? 1016 cm?2. We found that the thermal pressure within the G287.76-0.87 pillar is sufficiently high to make it stable for the surrounding hot gas and radiation feedback if the winds are not active. While they are active, stellar winds from the clustered stars sculpt the surrounding molecular cloud into pillars within the giant bubble around ? Carina. 2024. The Author(s).

GASP XVIII: Star formation quenching due to AGN feedback in the central region of a jellyfish galaxy
subject: galaxies: clusters: intracluster medium; galaxies: star formation
description: We report evidence for star formation quenching in the central 8.6 kpc region of the jellyfish galaxy JO201 that hosts an active galactic nucleus (AGN), while undergoing strong ram-pressure stripping. The ultraviolet imaging data of the galaxy disc reveal a region with reduced flux around the centre of the galaxy and a horse-shoe-shaped region with enhanced flux in the outer disc. The characterization of the ionization regions based on emission line diagnostic diagrams shows that the region of reduced flux seen in the ultraviolet is within the AGN-dominated area. The CO J2-1 map of the galaxy disc reveals a cavity in the central region. The image of the galaxy disc at redder wavelengths (9050-9250 reveals the presence of a stellar bar. The star formation rate map of the galaxy disc shows that the star formation suppression in the cavity occurred in the last few 108 yr. We present several lines of evidence supporting the scenario that suppression of star formation in the central region of the disc is most likely due to the feedback from the AGN. The observations reported here make JO201 a unique case of AGN feedback and environmental effects suppressing star formation in a spiral galaxy. 2019 The Author(s) Published by Oxford University Press on behalf of the Royal Astronomical Society.

GASP XXIII: A Jellyfish Galaxy as an Astrophysical Laboratory of the Baryonic Cycle
description: With MUSE, Chandra, VLA, ALMA, and UVIT data from the GASP program, we study the multiphase baryonic components in a jellyfish galaxy (JW100) with a stellar mass 3.2 1011 M o hosting an active galactic nucleus (AGN). We present its spectacular extraplanar tails of ionized and molecular gas, UV stellar light, and X-ray and radio continuum emission. This galaxy represents an excellent laboratory to study the interplay between different gas phases and star formation and the influence of gas stripping, gas heating, and AGNs. We analyze the physical origin of the emission at different wavelengths in the tail, in particular in situ star formation (related to H?, CO, and UV emission), synchrotron emission from relativistic electrons (producing the radio continuum), and heating of the stripped interstellar medium (ISM; responsible for the X-ray emission). We show the similarities and differences of the spatial distributions of ionized gas, molecular gas, and UV light and argue that the mismatch on small scales (1 kpc) is due to different stages of the star formation process. We present the relation H?-X-ray surface brightness, which is steeper for star-forming regions than for diffuse ionized gas regions with a high [O i]/H? ratio. We propose that ISM heating due to interaction with the intracluster medium (either for mixing, thermal conduction, or shocks) is responsible for the X-ray tail, observed [O i] excess, and lack of star formation in the northern part of the tail. We also report the tentative discovery in the tail of the most distant (and among the brightest) currently known ULX, a pointlike ultraluminous X-ray source commonly originating in a binary stellar system powered by either an intermediate-mass black hole or a magnetized neutron star. 2019.

GASP. XV. A MUSE view of extreme ram-pressure stripping along the line of sight: Physical properties of the jellyfish galaxy JO201
subject: Galaxies: clusters: intracluster medium; Galaxies: interactions; Galaxies: ISM
description: We present a study of the physical properties of JO201, a unique disc galaxy with extended tails undergoing extreme ram-pressure stripping (RPS) as it moves through the massive cluster Abell 85 at supersonic speeds mostly along the line of sight. JO201 was observed with multi-unit spectroscopic explorer as part of the GASP programme. In a previous paper (GASP II) we studied the stellar and gas kinematics. In this paper we present emission-line ratios, gas-phase metallicities, and ages of the stellar populations across the galaxy disc and tails. We find that while the emission at the core of the galaxy is dominated by an active galactic nucleus (AGN), the disc is composed of star-forming knots surrounded by excited diffuse gas. The collection of star-forming knots presents a metallicity gradient steadily decreasing from the centre of the galaxy outwards, and the ages of the stars across the galaxy show that the tails formed ? 109 yr ago. This result is consistent with an estimate of the stripping time-scale (?1 Gyr), obtained from a toy orbital model. Overall, our results independently and consistently support a scenario in which a recent or ongoing event of intense RPS acting from the outer disc inwards, causes removal and compression of gas, thus altering the AGN and star formation activity within and around the galaxy. 2019 The Author(s) Published by Oxford University Press on behalf of the Royal Astronomical Society.

Gastronomic delights for community growth: unravelling the impact of sustainable tourism in Sikkim, India
subject: categorical-content approach; community development (CD); gastronomy tourism (GT); narrative analysis; SGTD; Sikkim; sustainable gastronomic tourism development
description: Community development (CD) and sustainable gastronomy tourism development (SGTD) are mutually beneficial. Therefore, this study calls for a thorough investigation and interpretation of the phenomenon. In the context of Sikkim, India, this study examines the effects of SGTD on CD. The research question of whether sustainable gastronomy tourism (SGT) influences CD is addressed through a narrative analysis. The stories of ten local food vendors are gathered and examined using the categorical-content approach. However, the narratives indicate that local food vendors do believe that SGTD can act as a catalyst for local development, and that using traditional food as an alternative source of income can offer them a number of benefits. Other facets of gastronomic tourism are identified in the stories that may have unfavourable effects. Several ways to promote SGTD are suggested. The paper concludes that, to endorse gastronomic tourism (GT), local community involvement and strict policies are crucial. Copyright 2024 Inderscience Enterprises Ltd.

Gaussian MutationSpider Monkey Optimization (GM-SMO) Model for Remote Sensing Scene Classification
subject: AlexNet; Gaussian MutationSpider Monkey Optimization; generative adversarial network; scene classification; VGG19
description: Scene classification aims to classify various objects and land use classes such as farms, highways, rivers, and airplanes in the remote sensing images. In recent times, the Convolutional Neural Network (CNN) based models have been widely applied in scene classification, due to their efficiency in feature representation. The CNN based models have the limitation of overfitting problems, due to the generation of more features in the convolutional layer and imbalanced data problems. This study proposed Gaussian MutationSpider Monkey Optimization (GM-SMO) model for feature selection to solve overfitting and imbalanced data problems in scene classification. The Gaussian mutation changes the position of the solution after exploration to increase the exploitation in feature selection. The GM-SMO model maintains better tradeoff between exploration and exploitation to select relevant features for superior classification. The GM-SMO model selects unique features to overcome overfitting and imbalanced data problems. In this manuscript, the Generative Adversarial Network (GAN) is used for generating the augmented images, and the AlexNet and Visual Geometry Group (VGG) 19 models are applied to extract the features from the augmented images. Then, the GM-SMO model selects unique features, which are given to the Long Short-Term Memory (LSTM) network for classification. In the resulting phase, the GM-SMO model achieves 99.46% of accuracy, where the existing transformer-CNN has achieved only 98.76% on the UCM dataset. 2022 by the authors.

Gaze and Queer Autonomy? Representations and Possibilities on New Visual Media Landscapes in the Indian Context
subject: New media; Queer; Queerness; Visual
description: Representations of sexuality in Indian mainstream cinema tend to reinforce sexual differences, imbalances, and certain stereotypes that put queer identities in a disadvantageous position. The shift and transition from the monopoly of the state to an era of popular forms of entertainment enabled the centrality of debates on representations and sexuality. The study examines the representations of queerness that flourished on new visual media landscapes such as the OTT platforms Netflix and Amazon Prime Video that engaged in a new dialogue on queer representations and possibilities. The study attempts to analyze Super Deluxe (2019), Made in Heaven (2019) and Ajeeb Daastans (2021), as they become the representative form of cinema that marked the shift and engaged in a new dialogue on queer representations and possibilities. The study reads queer representation in light of the frameworks of gaze and homophyly to understand why they might offer different opportunities for representation and gaze.

GC-MS profiling of metabolites in blue and white varieties of heirloom butterfly pea (Clitoria ternatea L.) seeds
subject: Butterfly pea; GC-MS analysis; medicinal plant seed; phylogenetic proximity; phytocompounds
description: The Butterfly Pea is a tropical legume, a perennial herbaceous plant commonly found in Southeast Asia. The plant and its products are rich in bioactive ingredients, attracting the industrial and biopharmaceutical sectors due to their various applications. In this study, the blue and white flowered variety seeds of Butterfly Pea methanolic extract were comprehensively screened to identify the bioactive compounds and their drug-like properties. The methanolic extract was prepared by the cold maceration method, and the crude dried extract was subjected to GC-MS analysis for seed metabolite profiling. The chromatogram analysis revealed 39 abundant phytoconstituents, demonstrating the diverse chemical composition of the Butterfly Pea seeds. Among the identified compounds, the relatively abundant bioactive components in the blue variety seeds were stearic acid (64.6%), methyl stearate (54.0%), hexadecanoic acid, methyl ester (48.2%), and ethriol (35.9%). the white variety seeds primarily included palmitic acid (71.0%), hexadecanoic acid, methyl ester (53.4%), methyl stearate (42.0%), and hydrocinnamic acid (30.5%). Additionally, both varieties exhibited a diverse array of shared compounds reflecting their phylogenetic proximity. These metabolites are associated with key bioactivities in plant signaling and defense, playing vital roles in growth regulation, stress adaptation, and exhibiting potential antidiabetic properties. The research highlights the potential of the butterfly pea seeds as a valuable resource of active metabolites for vast research and therapeutic applications. 2025, Indian journals.
