This article examines how the early Pentecostal movement in Kerala created a liminal space for Dalits and women—groups historically marginalized by caste and patriarchy—to exercise spiritual agency and contest social hierarchies. Grounded in a Spirit-centered theology that emphasized charismatic openness and the democratization of spiritual gifts, early Pentecostalism disrupted conventional modes of authority and belonging. Drawing on Victor Turner’s theory of liminality, this study interprets this early period as a threshold moment wherein new forms of identity and communal life briefly emerged. While Pentecostalism offered a radically inclusive grammar of participation, its emancipatory potential was ultimately constrained by institutionalization and the reassertion of social norms. Nonetheless, within this fragile and contested space, Dalits and women found opportunities for voice, leadership, and embodied transformation rarely available in other ecclesial traditions. By recovering the theological and historical significance of this liminal journey, this article contributes to broader conversations on decolonial ecclesiology, Spirit-led resistance, and the ongoing tension between charisma and structure in Pentecostal movements.

Salinity stress represents a critical environmental constraint that significantly limits the development of tilapia aquaculture in brackish water environments. Its substantial impacts on fundamental physiological processes in fish, particularly osmotic balance, energy metabolism, and antioxidant defense mechanisms, have become a major scientific concern in aquaculture research. To systematically elucidate the molecular mechanisms underlying the response of genetically improved farmed tilapia (Oreochromis niloticus) to salinity stress and to test the hypothesis that it adapts through metabolic reprogramming for energy reallocation under such conditions, this study employed an integrated transcriptomic and metabolomic approach. Through a rigorously controlled experimental design with freshwater (0‰) as the control group and brackish water (24‰) as the experimental group, we conducted a comprehensive analysis of dynamic changes in gene expression profiles and metabolite spectra in the liver tissues of experimental fish. The study yielded the following key findings: First, salinity stress significantly suppressed growth performance indicators, including body weight and length, while simultaneously inducing extensive transcriptomic restructuring and profound metabolic remodeling in liver tissue. A total of 1529 differentially expressed genes (including 399 up-regulated and 1130 down-regulated genes) and 127 significantly differential metabolites were identified. Second, the organism achieved strategic reallocation of energy resources through coordinated suppression of multiple energy-consuming anabolic pathways, particularly steroid biosynthesis and fatty acid metabolism, with the remarkable down-regulation of Fasn, a key gene in the fatty acid synthesis pathway, being especially prominent. Energy-sensing and metabolic homeostasis regulatory networks played a central coordinating role in this process, guiding the organism through metabolic reprogramming by regulating downstream metabolic nodes. From a multi-omics integrative perspective, this study provides in-depth insights into the sophisticated metabolic remodeling and energy allocation strategies employed by GIFT to cope with salinity stress. These findings, particularly the suppression of fatty acid biosynthesis and the reprogramming of glycolysis/gluconeogenesis pathways, not only elucidate the molecular mechanisms by which teleosts achieve environmental adaptation through energy reallocation, but also provide actionable molecular targets for the selective breeding of salinity-resilient tilapia strains.

Shiitake mushrooms (Lentinula edodes) are widely consumed as a key health food in the Republic of Korea. However, they face declining production value and consumption, necessitating a shift from production-focused research to an understanding of consumer demand. The aim of this study was to quantify Korean consumers’ trade-offs among key shiitake attributes and to derive actionable marketing strategies to expand domestic consumption. We conducted an online survey (n = 500) to quantify consumer utility for four key attributes: cap size (two levels), cap color (two levels), origin (two levels: domestic (Korean) and imported (Chinese)), and price (four levels per 500 g). The results identified price as the most important attribute (relative importance = 46.41%), followed by origin (19.85%), cap color (17.10%), and cap size (16.64%). Utility analysis (part-worths) revealed a distinct dual preference: consumers value both low-priced shiitake (KRW 4000 (USD 2.9)/500 g) for personal consumption and high-priced options (KRW 13,000 (USD 9.5)/500 g) for gifting. Consumers showed a clear preference for dark-colored caps, while the aggregate-level utility difference between origin levels was small. A Logit model simulation indicated the highest predicted shares for profiles priced at KRW 13,000 (15.9%) and KRW 4000 (15.7%), consistent with a polarized value–premium structure. These findings indicate that Korean producers should adopt a dual strategy: developing low-cost products to stimulate general consumption while simultaneously marketing high-quality, dark-colored, domestically produced shiitake as premium gift items, thereby establishing effective food choice strategies in a competitive market. Although the empirical setting is the Republic of Korea (with ‘Chinese’ included only as an imported-origin level representing the main foreign competitor), the findings speak to broader specialty-food contexts where import competition and dual-purpose purchasing (everyday use vs. gifting) shape attribute trade-offs.

Understanding the factors that promote positive affect and achievement in gifted students is essential for supporting their holistic development and success. This study aimed to explore the relationship among meaning in life (presence and search), character strengths (creativity, perseverance, social intelligence), social connectedness, positive/negative affect, and perceived academic achievement among gifted students in Hong Kong, China. A total of 348 gifted students participated in this study, comprising 196 males and 152 females, aged 10 to 18 years. The students completed a cross-sectional online survey in August and September 2024. Mediation analyses were conducted using structural equation modeling with bootstrapping to estimate indirect effects. The results indicated significant indirect effects of meaning in life (presence and search) and character strengths (creativity, perseverance, social intelligence) on positive affect (β = 0.15 to 0.32, p < 0.05) and negative affect (β = −0.15 to −0.26, p < 0.05) via social connectedness, with small-to-moderate effect sizes. Additionally, significant indirect effects were observed for meaning in life and character strengths on perceived academic achievement via social connectedness (β = 0.13 to 0.20, p < 0.05), with small-to-moderate effect sizes. This research highlights the significant role of character strengths, meaning in life, and social connectedness in enhancing positive affect and perceived academic achievement, and reducing negative affect among gifted students.

The rapid expansion of Internet of Things (IoT) and mobile devices has intensified the demand for lightweight cryptographic algorithms capable of delivering strong security with minimal computational overhead. This work presents the SMA, a Secure Matrix-Based lightweight block cipher designed to meet these requirements through a 64-bit block and 80-bit key Substitution–Permutation Network (SPN) optimized for constrained environments. The SMA combines a nibble-wise PRESENT S-box with a fully index-based 2D matrix permutation to provide high non-linearity and efficient full-bit diffusion, supported by an enhanced key schedule that increases round-key diversity and mitigates key-dependent weaknesses. The proposed method replaces the complex linear diffusion layers used in existing lightweight ciphers such as GIFT, RECTANGLE, and PRESENT with a low-cost two-dimensional permutation that improves practical performance. Experimental evaluation demonstrates that the SMA achieves 98.5% non-correlated outputs, an average 50% bit error rate under both plaintext and key variations, and a 100% pass rate across fifteen NIST SP 800-22 statistical tests in nine data categories. Software-based implementation further confirms the correctness and applicability of the SMA for IoT-oriented simulation environments. Moreover, no exploitable differential or linear trails were identified across the full 20-round design. These results indicate that the SMA provides strong confusion, diffusion, and statistical randomness while maintaining competitive performance for secure IoT and mobile encryption applications.

This article draws on research in a Norwegian municipality to examine the affective aspects of teaching gifted students and to explore how systemic and cultural norms surrounding gifted education in Norway may shape teachers’ perceptions and practices. Teacher well-being is a concern for educational quality and sustainability, yet in gifted education, it is often overlooked. Giftedness refers to a high ability to learn faster, more complex or in greater depth than same-age peers when adequately supported. In Norway, teachers face contradictory signals concerning teaching the gifted: definitional ambiguity, limited training, strong egalitarian norms that make giftedness a contested category, and, at the same time, a strong principle of inclusive adapted education for all. Those combined may lead to ethical tensions that challenge teachers’ professional integrity and well-being. Such conditions can reduce teachers’ handlingsrom, meaning their space (room) for professional agency, within institutional, cultural, and policy frameworks. To investigate how such pressures shape teacher’s well-being, this study synthesises findings from four interrelated sub-studies conducted within a single research project on gifted education. Using a meta-ethnographic approach, we translated and integrated insights from the sub-studies to develop higher-order constructs not visible in the individual analyses. The synthesis identified three key dynamics: conceptual ambiguity, ethical strain under cross-pressure, and buffers as recalibrators of demands and resources. Together, these insights informed the Cross-Pressure Model for Teacher Well-being (CP-Well Model) developed in this study, which positions teacher integrity at the centre of professional well-being. We argue that teacher well-being in gifted education may depend less on individual resilience and more on systemic, cultural, and policy conditions. Addressing these cross-pressures requires structural change, supportive leadership, and sustained professional development to enable teachers to work with integrity. Full article

Gifted students with neurodivergent profiles such as ADHD, autism, or dyslexia demonstrate unique cognitive and learning characteristics that can shape their educational experiences and socio-emotional development. Often referred to as twice-exceptional (2e), these students benefit from environments that recognise their strengths while responding to their diverse learning needs. Understanding the interplay between giftedness and neurodivergence is therefore essential for fostering strengths-based environments to support these students’ overall well-being. This review focuses on 2e students with ADHD, a subgroup within the gifted population who remain underexamined in the current literature. While existing research has emphasised the academic and diagnostic complexities associated with this cohort, limited studies have focused on the socio-emotional factors influencing their development. This systematic view aimed to identify and synthesise findings from existing research on the socio-emotional factors influencing the mental health of gifted students with ADHD. A comprehensive search was conducted across the EBSCO, ProQuest, and ProQuest Dissertations & Theses databases. Following PRISMA guidelines, 10 studies out of 438 met the predetermined inclusion and exclusion criteria and were critically appraised using the JBI checklists for qualitative and cross-sectional designs. These 10 papers were categorised based on authorship, title, year of publication, population, study design, theoretical frameworks, key findings, and identified risk or protective factors. The findings indicate that gifted students with ADHD experience distinct challenges in forming and maintaining peer relationships. Additionally, the intersection of giftedness and ADHD is noted as a potential risk factor, rather than a protective factor, for lower self-esteem and social connectedness. The limitations of this review, along with implications for future research and educational practice, are discussed. Full article

Sweet bags were small, embroidered textile pouches used in the sixteenth and seventeenth centuries to carry fragrant substances, money, books, sewing tools, mirrors, or other personal items. They were often exchanged as gifts, used to preserve clothing in wardrobes, or used to protect against contaminated air. Beyond their material function, both their name and some of their uses suggest an olfactory dimension, as they were typically filled with aromatic herbs—combinations frequently recorded in recipe books, medical, and household manuals, including Countrey Contentments, or The English Husvvife, Praxis Medicinæ, or The Physitian’s Practise, and Exenterata, among others. Through close reading and literary analysis of such primary sources combined with a sensory approach, this article traces the possible ingredients of these pouches in Early Modern recipes and argues that their olfactory content positions them as objects of the “olfactory gaze” (Verbeek), thereby transforming them into elements of olfactory heritage. Ultimately, the article seeks to recreate the olfactory component of sweet bags within recipe-related practices, and broader domestic traditions of Early Modern England. Full article

The purpose of this study is to examine how the selective attributes of Heugimja Seolgi, a traditional Korean food, influence consumers’ purchasing behavior. Data were collected through an online survey of adults in their 20s to 60s residing in the Republic of Korea who had previously consumed Heugimja Seolgi. Most respondents were in their 30s (34.5%) and 60s (25.7%). A total of 342 valid responses were analyzed using SPSS 25.0. Diversity and image, as sub-factors of the selective attributes for Heugimja Seolgi, were found to have a significantly positive impact on repurchase behavior, whereas quality did not show a statistically significant effect. This finding suggests that to increase repurchase rates, these factors must be considered, as Heugimja Seolgi is commonly chosen as a meal replacement, snack, or gift. Consumers also place great importance on the hygiene, cleanliness, and image of the stores selling the product. Ongoing research in this area is essential for the sustainable development of the Korean rice cake industry and is expected to contribute significantly to promoting the cultural and nutritional significance of traditional Korean rice cakes.

Background: Despite many young players showing strong potential, only a small fraction succeeds in the critical transition from youth to elite senior football. This scoping review synthesizes research on the junior-to-senior transition in men’s football, identifying main topics related with barriers and facilitators in the transition. Methods: Searches were performed in four databases (PubMed, Scopus, SPORTDiscus, and Web of Science) according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA, 2020) guidelines, using the following keywords: “football*” OR football AND talent* OR “talent identification” OR “talent development” OR expert* OR gift* AND “junior-to-senior” OR “transition career” or “athlete career transition” OR “transition phase”. Original articles in English focused on the junior-to-senior process in male footballers were included. Results: From 5307 titles, 35 studies met eligibility criteria. The most examined themes were psychosocial factors, including social support, stressors, and resilience. The reviewed studies identified organizational structure and effective club communication as facilitators and emphasized the importance of physical attributes to meet senior-level demands. Conclusions: Overall, the junior-to-senior transition is multifaceted, shaped by psychosocial, organizational, and physical factors. Despite robust research, gaps remain; future longitudinal and interdisciplinary studies should inform evidence-based strategies for optimizing player development and retention. Full article

Cultural landscapes are facing increasing challenges in terms of sustainable financing, owing to fiscal austerity and limited public funding. This study explores tourists’ willingness to pay (WTP) for the conservation of cultural landscapes through Japan’s Furusato Nozei (Tax payment to hometown)—a policy that pairs tax deductions with tangible “return gifts,” institutionalising a form of mixed (or “impure”) altruism that can convert intention into action. Using a survey of 500 visitors to Shibamata, Tokyo, we estimate an integrative model that links psychological pathways (motivation → destination evaluation), behavioural investments (time, spending, and interactions with residents), and socio-demographic characteristics. To analyse the collected data, we use partial least squares structural equation modelling. Results reveal that interaction with local communities has the strongest direct effects on WTP, while motivation influences WTP indirectly through destination evaluation. Age shows a negative relationship, whereas marital status has a positive one; income and gender are not significant predictors. These findings suggest that institutional incentives embedded in Furusato Nozei can transform altruistic intention into actual financial support for heritage conservation. This study contributes theoretically by linking institutional design to behavioural intention–action gaps and practically by providing insights for participatory and incentive-based heritage financing. The findings are based on a single-site case in Shibamata, Tokyo, and should therefore be interpreted within its local and cultural context. Full article

This study examined the utilization of artificial intelligence (AI) in inquiry-based science learning among gifted and non-gifted students. The participants included 484 students (197 gifted and 287 non-gifted; 226 males and 233 females) who completed three validated questionnaire instruments: the AI-Assisted Scientific Inquiry Learning Questionnaire (AASILQ), the AI-Assisted Science Learning Questionnaire (AASLQ), and the AI Literacy Questionnaire (AILQ). Factor analyses confirmed four latent constructs in the AASILQ, two in the AASLQ, and four in the AILQ, with all scales demonstrating strong internal consistency. Group comparisons were conducted according to educational placement and gender. The results indicated significant differences regarding educational placement: gifted students reported lower levels of AI-Assisted Scientific Inquiry Learning yet demonstrated higher AI literacy and greater confidence in the safe use of AI. Gender analyses revealed that female students expressed heightened concern regarding privacy issues. These findings extend the literature on AI integration in science education by highlighting nuanced differences in how gifted and non-gifted learners engage with AI, thereby offering implications for the design of equitable and responsive AI-supported learning environments.

Sentiment analysis is essential for understanding consumer opinions, yet selecting the optimal models and embedding methods remains challenging, especially when handling ambiguous expressions, slang, or mismatched sentiment–rating pairs. This study provides a comprehensive comparative evaluation of sentiment classification models across three paradigms: traditional machine learning, pre-transformer deep learning, and transformer-based models. Using the Amazon Magazine Subscriptions 2023 dataset, we evaluate a range of embedding techniques, including static embeddings (GloVe, FastText) and contextual transformer embeddings (BERT, DistilBERT, etc.). To capture predictive confidence and model uncertainty, we include categorical cross-entropy as a key evaluation metric alongside accuracy, precision, recall, and F1-score. In addition to detailed quantitative comparisons, we conduct a systematic qualitative analysis of misclassified samples to reveal model-specific patterns of uncertainty. Our findings show that FastText consistently outperforms GloVe in both traditional and LSTM-based models, particularly in recall, due to its subword-level semantic richness. Transformer-based models demonstrate superior contextual understanding and achieve the highest accuracy (92%) and lowest cross-entropy loss (0.25) with DistilBERT, indicating well-calibrated predictions. To validate the generalisability of our results, we replicated our experiments on the Amazon Gift Card Reviews dataset, where similar trends were observed. We also adopt a resource-aware approach by reducing the dataset size from 25 K to 20 K to reflect real-world hardware constraints. This study contributes to both sentiment analysis and sustainable AI by offering a scalable, entropy-aware evaluation framework that supports informed, context-sensitive model selection for practical applications.

Twice-exceptional students, those who are both gifted and have an additional educational need, represent a complex and underserved population within education systems. While recognition of twice exceptionality has greatly increased in gifted education literature, little is known about the experiences of students and their families in Ireland, where no national policy or framework currently addresses their dual needs. This exploratory mixed-methods study aimed to examine the perspectives of 232 parents of twice-exceptional children who attended an enrichment summer programme for gifted students. Through an anonymous survey, the researchers investigated the frequency of specialised services provided for both giftedness and disabilities, as well as how satisfied parents were with these services. The findings indicated that, while two-thirds of students did receive special education support, the majority received no services focused on their giftedness. Parents expressed significantly higher dissatisfaction with gifted provisions than with special education, mentioning the lack of differentiation and access to advanced materials in class, as well as an emphasis on their child’s challenges, as opposed to their strengths. The study’s findings highlight substantial policy and practice gaps in Ireland’s current provision for twice-exceptional students and underscore the need for integrated support systems, teacher education, and inclusion of parent perspectives in educational planning.
