Beyond the Hegemony of National Language-in-Education Policy:Creating Multilingual Environments Through Local Agency in a Marginalized School Context in Bangladesh
No full textLanguage-in-education policy in Bangladesh emphasizes learners’ proficiency development in Bangla and English for national identity and human capital development. These language priorities based on ideological and economic rationalities pay little attention to the multilingual reality of the country. This raises questions as to how the policy unfolds in schools where majority of the students speak neither Bangla nor English. In this paper, we focus on one such school to examine how the language-in-education policy for human capital development relates to the school and its language situation. Drawing on a larger qualitative study, we analyzed interview and classroom observation data, and the analysis was informed by Bourdieu’s theory of practice, policy enactment literature, and the concept of agency. The findings revealed that students’ learning outcomes were constrained by the language-in-education policy as it could hardly be related to the local language situation. In this condition, the school and the teachers reworked the policy by creating a multilingual environment that went beyond the hegemony of the national language-in-education policy. The study contributes to understanding the role of agency in enacting language-in-education policy in marginalized school contexts
Supporting Emotional Wellbeing During Primary-Secondary School Transitions:Advice for Parents, Caregivers and Teachers
No full textPrimary-secondary school transitions mark a pivotal developmental milestone in children’s and their supporters’ lives. This accessible guide distils international research and practical insights into a reader-riendly resource focused on how parents, carers and teachers can support children’s emotional wellbeing during this significant period of change. Focussing on supporting the supporters, Supporting Emotional Wellbeing During Primary-Secondary School Transitions addresses some of the most frequently asked questions about how we can best support our children during this key transitional phase, as well as how we can help them navigate amongst other social, academic, environmental and personal transitions. Following an effective Q&A structure and a ‘dip in and out’ approach, chapters discuss topics such as puberty and related developmental aspects, support networks, the child’s voice, additional support needs and much more. This book includes illustrations and real-ife vignettes to help explain some complex concepts and scenarios. Written by two transitions experts, this essential resource is for parents looking for straightforward guidance on questions related to their child’s primary-econdary school transitions. With tips for teachers as well as parents and children, this may also be of interest to educators and school support professionals such as family liaison officers, educational psychologists and teaching assistants.</p
Political Theology, 1001 Cars Long:Emblems of Corporate Sovereignty in Netflix's <i>Snowpiercer</i>
No full textThis chapter reads the first season of Netflix's Snowpiercer as an exercise in political theology. Specifically, it argues that the season demonstrates the hermeneutic quality of political power: that the sovereign appears – and only ever appears – through its signs and symbols. The absent space of power remains absent, just as Mr Wilford remains absent from the train he created. Through exemplary analysis of key features of the first season's depiction of the train Snowpiercer (its use of corporate emblems, corporal and mirroring structures and punitive rituals) it is argued that Snowpiercer signals the repetition of tired political tropes and forms beyond their apparent collapse in the face of the climate apocalypse. This undermines science fiction's seeming potential to reimagine legal form and suggests instead a need for the self-conscious management of, or ‘working with’, inherited traditions of power
An introduction to computational argumentation research from a human argumentation perspective
No full textComputational Argumentation studies how human argumentative reasoning can be approached from a computational viewpoint. Human argumentation is a complex process that has been studied from different perspectives (e.g., philosophical or linguistic) and that involves many different aspects beyond pure reasoning, such as the role of emotions, values, social contexts, and practical constraints, which are often overlooked in computational approaches to argumentation. The heterogeneity of human argumentation is present in Computational Argumentation research, in the form of various tasks that approach the main phases of argumentation individually. With the increasing interest of researchers in Artificial Intelligence, we consider that it is of great importance to provide guidance on the Computational Argumentation research area. Thus, in this paper, we present a general overview of Computational Argumentation, from the perspective of how humans argue. For that purpose, the following contributions are produced: (i) a consistent structure for Computational Argumentation research mapped with the human argumentation process; (ii) a collective understanding of the tasks approached by Computational Argumentation and their synergies; (iii) a thorough review of important advances in each of these tasks; and (iv) an analysis and a classification of the future trends in Computational Argumentation research and relevant open challenges in the area.</p
Cartography of the unknown.:Walking, stitching, and transformation
No full textIn the tradition of creative practices’ embodied knowledge and research, this paper narrates my experience of trauma due to becoming suddenly disabled. The paper relates how engaging with stitching helped me deal with the sudden loss of a leg; cope with my new condition as a disabled person; repair my wounded self; find my feet into a new world; and open pathways of new knowledge and consciousness. The paper makes a strong case for the transformative potential of craft and craft-making by way of three complementary arguments that contribute to expanding and deepening research into the nature of craft widely, and of stitching specifically. First, it argues that stitching - and more widely craft- is a language in its own terms that allows expressing oneself before and beyond verbal language. Secondly, in offering the possibility to make sense “through the hands”, to reconfigure, and thus repair one wounded self, stitching transformative power goes well beyond its therapeutic nature as it is conventionally defined. Thirdly, it shows that stitching can open the doors onto a different type of knowledge that comes from a source other than the intellect or the rational mind, thus becoming a way of knowing in its own terms, and a mode of learning “other ways”
Influence of heat input and uniform temperature distribution during wire arc additive manufacturing process:a critical review
No full textThe effect of heat input and uniform temperature on the surface quality of wire arc additive manufacturing (WAAM) components is crucial for producing defect-free WAAM components. However, in most WAAM technologies, the heat input significantly impacts the layer-by-layer molten pool deposits, potentially leading to defect formation if not properly controlled and optimized. In this paper, we critically review the effect of heat input, uniform temperature distribution, interlayer temperature, and heat input parameters on the microstructure and mechanical properties of WAAM components during fabrication. Based on our findings, wire feed speed and torch speed parameters significantly control heat input in the WAAM process. It is established that optimizing parameters with a lower input can result in a finer and more homogeneous morphology, which can substantially enhance mechanical properties in the fabricated components. To manufacture high-quality metallic components that meet industrial demands, there is a need to provide an evidence-based framework for understanding these critical issues in the WAAM process, ensuring that WAAM processes are thoroughly planned before use in design and fabrication, which is one main contribution of this paper.</p

Energy harvesting performance of fluid-immersed bimorph FG-GPLRC sandwich microplates in thermal gradient and magnetic field environments:A modified strain gradient theory approach
No full textThis study presents a novel investigation into the energy harvesting capabilities of fluid-immersed bimorph functionally graded graphene nanoplatelet reinforced composite (FG-GPLRC) sandwich microplates under combined thermal gradient and magnetic field environments, considering various boundary conditions. To address the critical research gap in understanding size-dependent behavior of such systems, a theoretical framework combining modified strain gradient theory (MSGT) with first-order shear deformation theory (FSDT) is developed. The fluid-structure interaction forces are obtained through Navier-Stokes equations, while Hamilton's principle and Gauss's law are employed to derive the governing equations. Both the Halpin-Tsai micromechanical model and the law of mixtures are utilized to predict the effective material properties of FG-GPLRC with different graphene platelet distributions. The analysis reveals that series electrical configurations yield superior voltage and power output compared to parallel configurations in fluid-immersed environments. It is also shown that graphene platelet distribution patterns significantly influence energy harvesting efficiency, and thermal gradient effects substantially impact the system's performance. Comprehensive parametric analyses are provided examining the effects of piezoelectric connection types, boundary conditions, graphene distribution and loading, temperature variations, fluid depth, electrical load, and geometric dimensions on energy harvesting performance. The results of these analyses advance the understanding of micro-scale energy harvesting systems and provide valuable design guidelines for future applications.</p
An efficient temporal multiscale algorithm for simulating a long-term plaque growth problem in relation to power-law blood flows
No full textThis paper discusses the problem of non-Newtonian fluids with time multiscale characteristics, especially considering the type of power-law blood flow in a narrowed blood vessel due to plaque growth. In the vessel, the blood flow is considered as a fast-scale periodic motion, while the vessel wall grows on a slow scale. We use an auxiliary temporal periodic problem and an effective time-average equation to approximate the original problem. The approximation error is analyzed only for a largely simplified linear system, where the simple front-tracking technique is used to update the slow vessel wall growth. An effective multiscale method is then designed based on the approximation problem. The front-tracking technique also makes the implementation of the multiscale algorithm easier. Compared with the traditional direct solving process, this method shows a strong acceleration effect. Finally, we present a concrete numerical example. Through comparison, the relative error between the results of the multi-scale algorithm and the direct solving process is small, which is consistent with the theoretical analysis.</p
