The work of creating decolonized futures has been a particularly important undertaking in educational contexts, for which posthumanist and new materialist theories provide useful insights. Yet, how decolonization is to be achieved and whose responsibility it is remains up for discussion. This intra-view focuses on the tensions between decolonizing practices and posthumanism, and their implications foreducation: What can(’t) these theories do to decolonize education? And how do weengage in posthuman practices in education without overstepping, appropriating, or (re)colonizing Indigenous epistemologies? Thinking through these questions, in this intra-view we engage in a conversation with Michalinos Zembylas.

El manejo de residuos sólidos se ha configurado en una temática relevante y de creciente interés en la comunidad científica interesada en este tópico, dado que es de conocimiento público la dificultad que comporta su manejo y tratamiento, que generan daños complejos al medio ambiente. Este trabajo tiene el objetivo de analizar el proceso de digestión anaeróbica de residuos sólidos urbanos de Manta, desde la asunción del método dialéctico. Entre los resultados destaca que: El proceso de digestión anaerobia en fases separadas es un esquema novedoso que mantiene dos reactores en serie, en los que se llevan a cabo las fases de acidogénesis y metanogénesis, respectivamente. Del análisis realizado, se confirma que una de las posibles alternativas de respuesta para disminuir el problema en la fracción orgánica de los RSU es el hallazgo de un procedimiento energético, a través de su tratamiento por biogás. Palabras clave: Residuos sólidos urbanos; digestión anaeróbica; fases separadas, método dialéctico. Abstract The management of solid waste has become a relevant topic of growing interest in the scientific community interested in this topic, given that the difficulty of its management and treatment, which generates complex damage to the environment, is public knowledge. This work has the objective of analyzing the anaerobic digestion process of urban solid waste in Manta, from the assumption of the dialectical method. Among the results, it stands out that: The anaerobic digestion process in separate phases is a novel scheme that maintains two reactors in series, in which the acidogenesis and methanogenesis phases are carried out, respectively. From the analysis carried out, it is confirmed that one of the possible response alternatives to reduce the problem in the organic fraction of MSW is the discovery of an energy procedure, through its treatment by biogas. Keywords: Solid urban waste; anaerobic digestion; separate phases, dialectical method.

Martial arts organisations increasingly blend online and offline activity in order to cultivate specific qualities, skills and virtues. Students and instructors use blogs, chat fora, videos and podcasts to supplement their self- and shared cultivation, and this expanded with the COVID-19 lockdown in Britain. Martial arts schools have been closed and even disbanded while governments control people’s physical interactions through social distancing measures. This article draws on case studies of two British martial arts schools (Taijiquan and historical fencing) in order to examine how they have adapted to the lockdown. It offers these case studies to narrate the developments of how teachers and their localised communities have been creative during this moment of international crisis – from instructor-led online, live training sessions and lectures to student-led chat fora and movie nights for continued sociability and identity construction. In so doing, this article makes use of martial arts theories: Shared Cultivation (Jennings, 2010) and Martial Creation (Jennings, 2019) to explain how martial artists continue to develop through creative online endeavours and through their moving bodies within the confines of their homes. Finally, I argue that this creative martial arts cultivation during the COVID-19 pandemic might be extended to wider physical culture.

This paper synthesizes the main ideas of the Critical Theory of Sport, which has investigated the meanings of sport in capitalism since the late 1960s in France.The first section argues that sport is integrated into the capitalist development and contributes to convey the values of the industrial bourgeoisie since the endof the 19th century. In sports, competitiveness, the myth of struggle, triumph and success are staged. At the same time, sports constitute a training, a vehicle, forperformance and productivity at work. That section also discusses the different negative effects of sport in contemporary capitalism, which have been analyzedby the Critical Theory of Sport: from violence to machismo, from the corruption of sports institutions to the commercialization and spectacularization of sport,which is understood as a mechanism for distraction. The final section proposes a typology of attitudes of sports actors that legitimize and maintain the aforementionednegative effects of sport in the framework of current capitalism
