HSE-GNN-CP: spatiotemporal teleconnection modeling and conformalized uncertainty quantification for global crop yield forecasting
No full textGlobal food security faces escalating threats from climate variability and resource constraints. Accurate crop yield forecasting is essential; however, existing methods frequently overlook complex spatial dependencies driven by climate teleconnections, such as the ENSO, and lacks rigorous uncertainty quantification. This paper presents HSE-GNN-CP, a novel framework integrating heterogeneous stacked ensembles, graph neural networks (GNNs), and conformal prediction (CP). Domain-specific features are engineered, including growing degree days and climate suitability scores, and explicitly model spatial patterns via rainfall correlation graphs. The ensemble combines random forest and gradient boosting learners with bootstrap aggregation, while GNNs encode inter-regional climate dependencies. Conformalized quantile regression ensures statistically valid prediction intervals. Evaluated on a global dataset spanning 15 countries and six major crops from 1990 to 2023, the framework achieves an R2 of 0.9594 and an RMSE of 4882 hg/ha. Crucially, it delivers calibrated 80% prediction intervals with 80.72% empirical coverage, significantly outperforming uncalibrated baselines at 40.03%. SHAP analysis identifies crop type and rainfall as dominant predictors, while the integrated drought classifier achieves perfect accuracy. These contributions advance agricultural AI by merging robust ensemble learning with explicit teleconnection modeling and trustworthy uncertainty quantification
Six institutional intervention areas to support ethical and effective student use of generative AI in higher education: a narrative review
No full textThe integration of generative AI tools, such as ChatGPT, Gemini, and DeepSeek, into higher education offers transformative opportunities for personalised learning and academic productivity. However, their unregulated use raises concerns about academic integrity, critical thinking, and educational equity. This systematic review synthesises insights from 96 peer-reviewed articles, identifying six key intervention themes, namely, curriculum integration, policy and governance, faculty development, student-centred strategies, assessment adaptation, and technological infrastructure. Together, these themes form a comprehensive intervention framework designed to guide students’ ethical and effective engagement with AI. This review highlights the need for institutions to move beyond fragmented policies, fostering systemic cultural and pedagogical change to align AI use with authentic learning outcomes. By bridging theoretical gaps and providing actionable strategies, this framework equips educators and policymakers to scaffold responsible AI integration across diverse higher education contexts
Realising pedagogical love through Ubuntu: cultivating inclusion and undoing coloniality for pluriversity
No full textThis chapter illustrates how ubuntu principles can generate student growth and transformation in adult and higher education within and outside of southern Africa. Ubuntu principles include coexistence, compassion, dialogue, dignity and respect, love and solidarity. The author draws on literature to show that pedagogy rooted in ubuntu encourages participation and empathy which fosters belonging in the classroom; promotes dignity and respect based on love which facilitates critical dialogue for learning growth and student self-actualisation; emphasises diversity as a road to harmony among students and knowledge co-creation; and enhances student outcomes through compassion and interdependent learning. The author argues that when appropriately implemented and internalised in educational settings among teachers and learners, ubuntu principles can empower students to free themselves from academic and personal barriers used to justify exclusion, oppression and self-promotion over collective good. The author concludes that when ubuntu is performed and embodied in the classroom pedagogical love emerges: a more compassionate, inclusive and humane approach to teaching and learning. As such, ubuntu pedagogy provides a pathway to pluriversity, that is a pluriversal adult and higher education landscape based on cognitive and social justice. Therefore, this chapter contributes to pedagogical love and the ongoing dialogue about promoting inclusion and countering colonial legacies in education
Queering the code: performing queerness in George Cukor’s 1930s films
No full textBeginning with a contextualisation of how the Code and “coding” link to queerness, this article will closely analyse examples of queer performance signifiers in characterisation, costume and dialogue within George Cukor’s 1930s films. As has already been noted by scholars such as Richard Maltby and Thomas Doherty, the lead up to and subsequent “enforcement” of the Code led filmmakers to include implicit and connotative indicators of sex, violence and criminal activities in their stories. In this article, I will investigate how filmmakers generally, and Cukor in particular, struck a precarious balance between denotative and connotative indicators of queerness in their films. I do this by accompanying detailed textual analysis of some of Cukor’s films, in a career that spanned (and outlasted) the Code’s enforcement, with an exploration of interactions between Cukor and his producers and the Code officials. As a result, I will chart developments in queer representation in terms of theatricality and performance, as well as the ways the PCA responded to such depictions, to determine how filmmakers were/were not able to represent queer lives in Code-era Hollywood
What is the criminological value of fiction? Examining postcolonial speculative storytelling as a site for theory construction, analogy and pedagogy
No full textIn response to calls to counter-colonial legacies in criminology and to improve inclusivity, I examine the criminological value of postcolonial speculative fiction as a site for theory construction, analogy and pedagogy. This conceptual and qualitative project sought to develop students’ critical thinking skills and empathy through fiction and to generate ‘new’ and collaborative ways of thinking about harm, crime and justice. Participants were asked to read two short stories about sexual and gender-based violence against women and girls. The fiction was chosen to inspire critical dialogue in a predominantly white classroom. I begin by outlining the need for fundamental change in criminology’s approach to critical inquiry then explore how fiction can provide an avenue for pedagogical transformation. I find that fiction provides a site on which students can compare and interpret crime, harm and justice in the social world; moreover, that fiction can help students to engage with difference

Antecedents of test automation adoption in DevOps Continuous Testing: a systematic literature review through the TOE framework
No full textBackground: The rapid evolution of software engineering has positioned DevOps practices and Continuous Testing (CT) as critical approaches for achieving speed, quality, and reliability in software delivery. Test automation is central to CT, yet its adoption remains inconsistent due to a complex interplay of technological, organizational, and environmental conditions. Objective: This study employs a systematic literature review guided by the Technology–Organization–Environment (TOE) framework to identify, categorize, and synthesize the antecedents that influence the test automation adoption in DevOps continuous testing. Methods: Using the PRISMA protocol, 49 peer-reviewed studies published between 2015 and 2025 were systematically analyzed, yielding 61 distinct factors comprising 29 technological, 19 organizational, and 13 environmental antecedents. These factors were further consolidated into thematic clusters to enhance analytical clarity and reduce fragmentation. Results: The findings demonstrate that technological and organizational drivers, including relative advantage, compatibility, top management support, and employee competence, dominate the literature, while environmental influences such as competitive pressure, regulatory requirements, and vendor ecosystems are comparatively underexplored. This imbalance indicates that although the TOE framework is widely applied in technology adoption studies, empirical research has given greater attention to internal adoption enablers than to external pressures. By simplifying and synthesizing the factors into coherent sub-themes, this study contributes to both theory and practice by offering a structured lens through which test automation adoption can be examined in the DevOps CT context. Theoretically, it validates the relevance of TOE for analysing multidimensional adoption dynamics, while practically, it provides managers with evidence-based insights to prioritize critical factors when planning automation initiatives. Methodologically, it demonstrates the importance of transparent and replicable review processes for advancing cumulative knowledge.Conclusion: Overall, the study bridges fragmented findings into a coherent framework and strengthens understanding of adoption strategies in continuous testing environments
Security risks to commercial ships in the Arctic Ocean due to high tension among states
No full textNavigation of ships in the Arctic Ocean is beneficial for world trade. However, ship security threats may appear due to maritime disputes. This paper aims to identify navigation security risks at different escalation levels among arctic states. In this paper, a conflict escalation game theory for three Arctic states is carried out. At each escalation scenario, an aggressor state has the option to practice certain tactics. Tactics were selected by examining similar maritime dispute conflicts, such as military exercises, rescue operations, and broadcasting safety messages to claim territorial rights in dispute sea zones. Then, escalation scenarios are examined, showing the navigation threats for commercial ships. Results show that a middle-level escalation by an aggressive state could be beneficial to achieving its territorial claims. On the other hand, several navigation risks could cause maritime casualties in a sensitive area. Several studies have covered the issue of safety navigation in the Arctic Ocean and the need for cooperation among states. The originality of this paper lies in examining how each escalation phase could cause risk to commercial ships, urging the need to establish safe navigation zones in the area
Consuming queerness: Jeffree Star and the paradox of profit and pleasure in the queer male beauty influencer
No full textChen and Kanai (2021) raise debates about a privileged subset of gay men occupying the beauty space as equal, if not more compelling, in fulfilling contradictory postfeminist demands of authenticity and femininity. The suggestion is that queer beauty influencers can embody idealistic postfeminist traits without the stigma a woman may face for doing the same. This paper explores a counterargument for this performance of hybridised gender and sexuality, in that the repetition of gender performatives through the queer body is an attempt to ‘re-present’ the social media beauty sphere through a queer lens where wearing makeup is an act of resistance. Using the influencer and makeup brand owner Jeffree Star as a case study, I argue that the queer beauty influencer exists as a body for fantasy projection, with makeup acting as the mediator for affective transference to bestow the audience with the transformative effect of queer resistance. However, the influencer and audience become bound back to the neoliberal ideals from which they attempt to break free. In positioning their own brand of cosmetics as a conduit through which their audience can obtain a sense of queer resistance, it ties the influencers and their audiences back to a capitalist framework
