From Margins to Pluriversality: Refusal, Reconstruction, and Decolonial Futures
Authors: Goodell Ugalde Elliot
Published: February 2025

This document examines the interplay between Audra Simpson's “politics of refusal” and Subcomandante Marcos' “pluriversalism”—both emerging from postcolonial discourse on Turtle Island—as frameworks aiming for self-determined governance that authentically acknowledges Indigenous knowledge(s) and ways of being. Simpson advocates for an emancipatory refusal to accept settler-state recognition, which often marginalises Indigenous perspectives and relegates them to a “peripheral” or “deviant” status within educational institutions and policies. In contrast, Marcos' pluriversalism, while also challenging the state's homogenising force, promotes a dialogical engagement that incorporates Mesoamerican knowledge(s) to enrich mainstream discourses, fostering “border thinking” or “border epistemology.”
This analysis proposes that Simpson's approach effectively deconstructs prevailing hierarchical knowledge structures within education, while Marcos' method seeks to reconstruct more inclusive paradigms where diverse epistemologies coexist without perpetuating colonial dominance. Thus, the thesis advocates for a two-step decolonial process with significant implications for educational practice, policy, and pedagogy: (1) Implementing Simpson's politics of refusal to critically dismantle the dominance of colonial epistemologies in curricula, teaching methods, and educational policies, effectively breaking down hierarchical relationships between colonial and Indigenous knowledge systems; and (2) Employing Marcos' pluriversal approach to reconstruct educational paradigms, fostering policies and pedagogical practices that support the equitable coexistence of different, and often competing, epistemologies and ontologies. This dual strategy aims to transform educational systems, preventing the perpetuation of colonial imbalances and promoting a truly inclusive, pluriversal educational landscape.

Compliance or Culture Shift: Reflecting on the Impact of Education Inspection on Educational Institutions
Authors: Joana Luciana , De Carvalho Maria João
Published: February 2025

This reflective work delves into education inspection as an entity operating across various countries. It draws from international organizations, particularly the OECD, for operational guidelines and support to ensure the quality and evaluation of educational services, and is seen as pivotal in evaluating and monitoring educational institutions in many countries. Inspectors gauge education quality and hold schools accountable for achieving teaching, organizational, and leadership objectives. Despite recognizing the diversity of educational systems and governmental mechanisms from a European standpoint, their actions have both positive outcomes. These comprise organizational improvement through fostering self-evaluation and guiding organizational changes, and unintended negative consequences, including minimal impacts on student progress and increased workload for educators, highlighting the complex nature of inspection systems. Inspection systems exert pressure on schools, fostering intentional consequences and serving as benchmarks for improvement. It can be concluded that globalization drives convergence in methodologies and shapes educational policies across nations.

Exploring the Environmental in South African Educational History
Authors: Chisholm Linda
Published: February 2025

This article takes a small part of South Africa’s oppositional history – the educational initiatives of social actors in exile – to show that ideas about environmental education were present in exile as much as in South Africa’s internal anti-apartheid movement. It builds on a South African historiography that problematises universalising notions of ‘development’ drawn from colonial modernisation discourses and tied to Western models of development. It focuses on the inclusion of Development Studies and environmental education in the curriculum of the exiled African National Congress’s (ANC’s) Solomon Mahlangu Freedom College (SOMAFCO) in the 1970s. Drawing on primary sources in the University of Fort Hare’s Liberation Movement Archives, the article argues that while the curriculum was part of a wider developmentalist discourse emerging in the post-WWII era; it aimed - unlike the apartheid curriculum which sought to construct and underline difference - to counter colonial racist discourses, and included environmental education in the curriculum at the suggestion of UNESCO. It could be seen as an early form of “decolonial” education. This case study is significant for deepening understanding of the history of environmental education in the global South.

Trauma, Resonances, and Transformations: Gaming as Heuristic Mode for Doing History
Authors: Camarda Sandra
Published: February 2025

This paper examines the potential of video games as a heuristic tool for engaging with history, particularly in the context of traumatic events and contested narratives. Traditionally, video games have been dismissed as trivial entertainment, unsuitable for addressing complex historical topics. However, new paradigms challenge such perceptions by exploring how ludonarratives – stories shaped by game mechanics –can facilitate transformative learning. By shifting players from passive spectators to active participants, games offer immersive experiences that can encourage critical engagement with historical events. The emotional impact of these experiences, supported by empirical studies, has the potential to promote empathy, understanding, and social change. Building on theories of resonance and transformative learning, this contribution advocates for a re-evaluation of video games’ role in historical education, emphasising their ability to provide meaningful, multi-perspective experiences that deepen our understanding of the past and its relevance to contemporary issues.

The Culture of Trauma and the COVID-19 Crisis
Authors: Novella Enric
Published: February 2025

This article reviews the genealogy and main assumptions of trauma culture in view of its extensive application during the recent COVID-19 pandemic. First, it summarises the crystallisation and development of the contemporary doctrine of (psychological) trauma in clinical psychiatry, psychopathology and psychoanalysis. It then presents the (problematic) translational concept of cultural trauma and offers some reflections on the global understanding of human catastrophes (caused by either collective violence or natural disasters) as traumatic events. Finally, it offers some concluding remarks on the contrast between the (relative) relevance of the trauma narrative in accounting for individual suffering and its (limited) performance in reflecting the final course of a health crisis that in its early stages seemed to threaten our way of life and our values.

Rethinking Readings About the Past of School and Education Between Worlds
Authors: Batista da Silva Vivian , Gonçalves Vidal Diana , Godinho Lima Ana Laura , Bontempi Jr. Bruno
Published: February 2025

This paper introduces the book Rethinking Centre-Periphery Assumptions in the History of Education: Exchanges Among Brazil, USA, and Europe, recently published by Routledge, as a result of the FAPESP Thematic Project No. 2018/26699–4 entitled Knowledges and practices at the borders: for a transnational history of education (1810–). It is structured in two parts. The first part evinces the exchanges established between Brazil and the USA, with a focus on the circulation of subjects and pedagogical models. The narrative starts in 1884 with the trip of Maria Guilhermina Loureiro to the USA and extending to 1960 with the connections between New Education and Modern Architecture. Along the way, it deals with the education debates carried out in the state of São Paulo around the writing of the report Education in the State of São Paulo (1903), and the sojourn of Brazilian educators in the Columbia University Teachers College (NY) from 1920 to 1960. In the second part, the circle is widened, incorporating the exchanges with Europe, particularly with France, England, and Portugal. Here we conduct analyses about the circulation of artifacts such as desks, parietal charts, and school manuals, as well as of models of representation such as Pictorialism photography.

Breaking Barriers by Enhancing Collaboration Between Schools, Communities, and Spanish-speaking Immigrant Parents
Authors: Batarse Aidee
Published: February 2025

There are barriers that interfere with parental involvement in their children's education in many schools in the U.S. However, additional barriers are often encountered by immigrant parents across our country. This investigation proposes practices that will better serve this population and reduce the barriers that affect their school engagement. One guiding question for this study is: What actions could be implemented to foster more effective collaboration between schools, communities, and Spanish-speaking immigrant parents? The objective of this study was to create a proposal for school personnel and Spanish-speaking immigrant parents to collaborate more effectively in terms of their children's education. The theoretical framework was guided by Epstein’s (1987) overlapping spheres of influence theory and Epstein’s and Sheldon’s (2022) framework of the six types of involvement. These theories provided a solid foundation and guided this study to create a proposal on how to alleviate the barriers that immigrant parents face when trying to engage in their children's education. The methodology used a qualitative research design with a phenomenological approach that examines the experiences of eight participants using semi-structured interviews. The proposed actions are directed at educators and administrators to improve immigrant parents' collaboration and promote a more inclusive and enriching educational environment, generating a positive impact on their children's education.

Resumen:
En el artículo se examina el funcionamiento de la censura eclesiástica en el arzobispado de México durante el gobierno de Pelagio Antonio de Labastida y Dávalos (1863-1891). En este periodo, la política se construyó bajo los principios del liberalismo y arribaron al país diversas denominaciones protestantes, luego de que la Constitución de 1857 estableciera el Estado laico. Ante este panorama, la Iglesia nacional reorganizó la vida pública del clero y los seglares, procurando que el catolicismo tuviera una fuerte influencia en el ámbito editorial. La censura eclesiástica en el siglo xix mexicano es un tema pendiente en la historiografía. Este artículo constituye un aporte al tema. A partir del análisis de documentos del Archivo Histórico del Arzobispado de México, se argumenta que el impreso religioso continuó constituyendo un negocio lucrativo en la segunda mitad del siglo XIX, que el clero diocesano intentó encauzar a sus líneas de acción política y social.

Ecclesiastical censorship during the archbishopric of Pelagio Antonio de Labastida y Dávalos
(1863-1891)
Abstract:
The article examines how ecclesiastical censorship worked in the archbishopric of Mexico during the government of Pelagio Antonio de Labastida y Dávalos (1863-1891). During this period, national policy was built on the principles of liberalism and various Protestant denominations arrived in the country once the Constitution of 1857 established the secular State. In this context, the Catholic Church reorganized the public life of the clergy and laities, with the objective that Catholicism would have a strong presence in the editorial field. This article constitutes a contribution to the subject of ecclesiastical censorship in the Mexican 19th century a topic that has garnered little attention from historians. Based on the analysis of documents from Archivo Histórico del Arzobispado de México, it argues that religious prints continued to represent a lucrative business in the second half of the 19th century, which the diocesan clergy used with advantage to promote its political and social projects.

Resumen:
A partir de periódicos y revistas, libros y representaciones, este artículo explora dos tendencias aparentemente contrarias pero paralelas a lo largo de la República Restaurada. Por un lado, las ambigüedades y tensiones en los libros de texto en torno al alcance y definición de la moral civil en la vida ciudadana; por el otro, las propuestas y los argumentarios de variadas expresiones católicas alrededor de la vindicación y pertinencia de la virtud religiosa para el devenir nacional. El análisis de los lenguajes conduce al esbozo de un conjunto de lenguajes en torno a la relevancia de los valores en la configuración de los ciudadanos y de un Estado oficialmente laico, pero sujeto a una alguna indeterminación ética y a una evidente presión católica. En suma, el texto indica un horizonte de suma viveza, ajeno a una visión uniforme de la victoria liberal y distante de la mera organización del estado reformista.

Attempts at secularization and reaffirmations of sacredness around civil morality during the Restored Republic
 
Abstract:
Based on newspapers and magazines, books and performances, the article explores two apparently contrary but parallel trends during the Restored Republic. On the one hand, the ambiguities and tensions in textbooks regarding the scope and definition of civil morality in the lives of citizens; and on the other, the proposals and arguments of various Catholic expressions around the vindication and relevance of religious virtue for the nation’s future. The analysis of languages delineates a set of languages around the relevance of values in the configuration of citizens and an officially secular state, but subject to a certain ethical indetermination and evident Catholic pressure. In short, the text reveals an extremely vivid horizon, alien to a uniform vision of liberal victory and distant from the mere organization of the reformist state.

Insect vocabulary reflecting effects on objects of the surrounding world: lexical interpretation
Authors: Xu Linlin
Published: February 2025

This article is devoted to the component and comparative analysis of the semes of vocabulary denoting insects, which contains a differential feature of the aspect of insect impact on objects of the surrounding world in Russian and Chinese. The purpose of the article is a comparative analysis of the vocabulary denoting insects in Russian and Chinese, containing a differential feature of the aspect of insect impact on objects of the surrounding world. The subject of this article is the vocabulary that designates insects and reflects their impact on objects in the world around them in Russian and Chinese. The object of the study is 28 lexemes that indicate a differential feature of the aspect of insect impact on objects of the surrounding world in Russian and 42 lexemes in Chinese, which were selected in dictionaries.   The following methods are used in this study: classification, semantic analysis, component analysis and comparative analysis. This aspect of vocabulary related to insects has not been studied. The analysis revealed differential semes in the differential features of the aspect "insect impact on objects of the surrounding world" in Russian and Chinese, as well as differences and similarities in the representation of these features in the two languages. The article notes that in Russian, 20.58% of lexemes refer to the general characteristics of insect exposure to someone and something, while in Chinese this figure reaches 46.15% (in accordance with the selected corpus of entomonyms).It was found that in the Russian language, the lexemes and the effects of insects on objects in the surrounding world are mostly characterized in a negative way. The definitions focus on the harmful nature of the effects of insects on flora, including agriculture, fauna and humans, as well as on human household items. In Russian cases, there is a beneficial effect of insects on objects of the surrounding world. In Chinese, insects are also divided into harmful and beneficial, depending on their role in the ecosystem. In their definitions, a clear juxtaposition of beneficial and harmful insects is carried out, the different nature of the impact of insects on the ecosystem during their metamorphosis and depending on external conditions is recorded.
Robustness and Safety of Net-Based Debris Capture Under Deployment and Environmental Uncertainties
Authors: Boonrath Achira , Botta Eleonora M.
Published: February 2025

Tethered net systems are considered one of the most effective solutions for addressing the problem of space debris. However, it is crucial to study the robustness of net-based debris capture in the presence of a wide range of possible activation and environmental uncertainties. The aim of this study was to analyze the limitations and operational envelope of tethered net systems in capturing space debris, with a particular focus on robustness and safety. The success of capture in nonnominal conditions was investigated, with errors considered in the target position, angular velocity, and parameters concerning the ejection of the net. In the sensitivity study, a capture quality index and mission safety factor were used to evaluate the success or failure of capture in an automated way. The quantitative relationships between relative parameter errors and capture evaluation metrics are also presented. The results of the sensitivity studies are promising and suggest that the target capture is robust to inaccuracies in the mission parameters beyond what is expected in reality.
Secondary Combustion of Micron-Sized Magnesium Powder to Enhanced Kerosene-Fueled Scramjet Thrust
Authors: Wang Xu , Liu Jiaxun , Liu Yongqi , Dou Suyi , Li Mengxiong , Xu Xu , Yang Qingchun
Published: February 2025

In the pursuit of enhancing the thrust performance of scramjet engines under extreme conditions, a novel approach known as powder-enhanced scramjet (PES) was designed, incorporating secondary combustion between magnesium powder and combustion products of kerosene fuel. In this study, simulated air enters the combustor at Mach 2.0 and a total temperature of 1600 K, with an RP-3 equivalence ratio of 1.0. Magnesium powder was injected into the combustion products of kerosene for secondary combustion in the midsection of a direct-connected scramjet. Thrust performance is evaluated by measuring inner wall pressure along the flow. This study explores the impact of various structural configurations and powder–gas ratios on PES thrust performance. Results affirm the feasibility of the PES concept, revealing a specific thrust gain of up to 28.8% with the addition of 7.5% magnesium powder. Magnesium powder primarily reacts with carbon dioxide and water vapor in combustion products, as confirmed through product analysis. Among the tested structural configurations, the approach employing a central strut for magnesium powder injection and mixing promotion exhibits comprehensive performance, considering basic specific thrust, specific thrust gain, and condensed-phase product deposition. Within a 10% powder–gas ratio, increasing the proportion of injected powder significantly improves engine thrust performance. However, beyond 9%, the rate of specific thrust gain increase begins to decelerate, suggesting an optimal range for powder injection.
Aerodynamic Performance of a Hovering Quadcopter Using the Unsteady Vortex Lattice Method
Authors: Gordillo Andres M. Perez , Escobar Jaime , Poroseva Svetlana V. , Mejia Omar D. Lopez
Published: February 2025

Quadcopters are one of the most used configurations to develop unmanned aerial vehicles for civil and military applications. The flow dynamics developed by the four rotors of a quadcopter is complex due to the interaction between the rotor wakes and the quadcopter fuselage. In the present study, the flow simulations of three cases were conducted: a single operating rotor, four operating rotors (no fuselage), and a simplified quadcopter operating at hover, in order to better understand the flow dynamics and to estimate the quadcopter aerodynamic performance. The simulations were based on the unsteady vortex lattice method (UVLM) with a viscous correction. In particular, the simulation of the simplified quadcopter and rotor tip phasing showed an asymmetrical pressure coefficient distribution on the rotor blades. With this configuration, the [Formula: see text] distribution depends on the blade position with respect to the fuselage. Computational results of the quadcopter aerodynamics performance were compared with experimental measurements from the bench (single rotor) and flight tests (complete quadcopter). A good agreement was observed between the numerical and experimental results for the thrust, whereas the torque was underestimated.
Aerodynamic Characteristics of Aircraft Model with Cable Suspension System under Rotary Motion

Published: February 2025

A wind-tunnel test of rotary motion around a velocity vector is a crucial method for investigating the intricate maneuvering characteristics of fighter aircraft, including spin and high-angle-of-attack maneuvers. In this paper, a method for constant rotary angular velocity motion is proposed, using a novel six-degree-of-freedom cable-driven parallel suspension mechanism (CDPSM). The correlation between the aircraft model’s attitude angles and rotary motion parameters is established, and a closed-loop control algorithm is developed, employing cable length as a variable to achieve precise motion control. Taking the standard dynamic model as an example, an integrated design of the model-balance-support system is performed, and measurements of static and dynamic aerodynamic characteristics are conducted in a low-speed wind tunnel, encompassing steady and oscillatory spin at high angles of attack. The results demonstrate that the CDPSM facilitates rotary motion around velocity vector, and the proposed design approach proves to be effective and feasible. Through the acquisition and analysis of aerodynamic data, it is observed that parameters such as the half-cone angle, angular velocity, and oscillatory spin modes significantly influence the aerodynamic characteristics. This research provides technical support for modeling unsteady aerodynamics at high angles of attack and analyzing spin characteristics.
Aeroacoustic Analysis of Ducted Contra-Rotating-Rotor Unmanned Aerial Vehicles in Hover
Authors: Zhao Zhiheng , Yang Cheng , Jiang Weikang
Published: February 2025

This work investigates a ducted contra-rotating-rotor unmanned aerial vehicle (UAV) whose aeroacoustic properties are less known compared to quadrotor UAVs. Two factors complicate the aeroacoustic analysis of this new design: the aerodynamic interaction among coaxial contra-rotating rotors and motor struts introduces additional source mechanisms, and acoustic scattering on duct walls further complicates the acoustic propagation process. A hybrid computational aeroacoustics (CAA) method is developed to project the aeroacoustic sources onto the in-duct modal space, allowing one to link various aeroacoustic sources to the acoustic far field through duct modes. An intriguing finding is that rotor–rotor interactions, the main source mechanism in open contra-rotating rotor propulsion systems, dominate acoustic far field only at even harmonic orders of blade passing frequencies (BPFs). A modified Tyler–Sofrin criterion has been derived to explain the underlying physics, where it is shown that the rotor–rotor interaction noise excites plane wave mode that couples to the acoustic far field. Conversely, at odd harmonic orders of BPFs, the rotor–strut interaction dominates the acoustic far field through the lower-order duct modes following the classical Tyler–Sofrin criterion. These results suggest the potential of exploiting mode scattering effects among rotors and struts, as well as the duct cutoff effect for significant noise reduction in ducted UAVs.
Loosely Coupled Fluid–Thermal-Ablation Analysis Strategy Based on Dynamic Flight Trajectory
Authors: Sivri Sezer , Özden Kamil , Gülay Emrah
Published: February 2025

In the context of designing supersonic and hypersonic missiles, it becomes imperative to conduct aerodynamic heating analyses, a task demanding time-dependent conjugate heat transfer (CHT) analyses that can be computationally expensive. This study introduces a time-efficient, loosely coupled fluid–structural thermal analysis method, tailored to the time-dependent flight trajectory. Loosely coupled analysis solves the fluid and structural equations independently and exchanges data at the interface between the two domains. To validate its efficacy, this proposed method is implemented on two distinct missile configurations with separate flight scenarios. The time-dependent temperature data, acquired through the loosely coupled analysis, are compared against results from the tightly coupled approach, actual flight data, and other established reference sources. Additionally, an ablation method using the heat of ablation formulation is coupled to the aerodynamic heating to approximately compute the recession. Also, a test problem is solved to validate the ablation method. The outcomes of this investigation reveal highly promising results. The findings of this research underscore the potential of the loosely coupled analysis strategy as a promising approach for conducting trajectory-based aerodynamic heating analyses of supersonic and hypersonic missiles. Notably, this approach offers reduced computational demand compared to the tightly coupled approach while maintaining the accuracy of the results.
