EFFECT OF Fe— Co — Cr CONTENT AND MECHANICAL ACTIVATION ON COMBUSTION IN A Ni—Al—(Fe—Co—Cr) SYSTEM
Authors: КОЧЕТОВ Н.А. , БУСУРИНА М.Л.
Published: July 2024

Проведено исследование влияния механической активации и количества связки Fe + Co + Cr на скорость и максимальную температуру горения, удлинение образцов в процессе горения, размер композитных частиц и выход смеси после активации, фазовый состав и морфологию продуктов синтеза в системе Ni—Al—(Fe—Co—Cr). Механоактивация смеси Ni + Al + x(Fe + Co + Cr) позволила реализовать горение образцов при комнатной температуре при содержании связки Fe + Co + Cr до 40 %. Активация смесей увеличила скорость и температуру горения, удлинение образцов продуктов и их пористость, уменьшила их прочность. Возрастание содержания связки Fe + Co + Cr в активированной смеси Ni + Al + x(Fe + Co + Cr) привело к увеличению выхода смеси после механоактивации, уменьшению размера композитных частиц и удлинению образцов продуктов синтеза. Зависимость скорости горения активированных смесей от содержания связки Fe + Co + Cr немонотонна, имеет максимум при содержании связки 10 %. Методом СВС синтезированы высокоэнтропийные сплавы — твердые растворы на основе интерметаллидов NiAl и Ni3Al.

The influence of mechanical activation and amount of Fe + Co + Cr binder on the combustion rate and maximum temperature, sample elongation during combustion, composite particle size and mixture yield after activation, phase composition and morphology of synthesis products in the Ni–Al–(Fe–Co–Cr) system was studied. Mechanical activation of the Ni + Al + x(Fe + Co + Cr) mixture allowed the samples to burn at room temperature with a Fe + Co + Cr binder content of up to 40%. Activation of the mixtures increased the combustion rate and temperature, sample elongation and porosity, and decreased their strength. An increase in the Fe + Co + Cr binder content in the activated Ni + Al + x(Fe + Co + Cr) mixture led to an increase in the mixture yield after mechanical activation, a decrease in the composite particle size and an elongation of the synthesis product samples. The dependence of the combustion rate of activated mixtures on the content of the Fe + Co + Cr binder is non-monotonic, and has a maximum at a binder content of 10%. High-entropy alloys – solid solutions based on intermetallic compounds NiAl and Ni3Al – were synthesized by the SHS method

Рассматривается дозвуковое турбулентное горение предварительно перемешанной метановоздушной смеси в модельном канале с обратным уступом (P. Magre и др., ONERA, 1975–1989). В экспериментах воспроизведены базовые физические механизмы, характерные для процессов горения в газотурбинных установках. Дан краткий обзор предыдущих работ по численному моделированию этих экспериментов. Описаны новые результаты численного исследования режима стабилизированного горения в данной установке. Проведено сравнение нескольких подходов к описанию турбулентного горения из класса PaSR (partially stirred reactor — модели реактора частичного перемешивания) с квазиламинарным подходом. Представлена модель переменных турбулентных чисел Прандтля и Шмидта, и рассмотрено ее влияние на воспроизведение данного течения в расчете.

Subsonic turbulent combustion in a premixed methane—air mixture in a model channel with a backward step is considered (P. Magre et al., ONERA, 1975–1989). The main physical mechanisms characteristic of combustion in gas turbine combustors are reproduced in experiments. A brief overview of previous numerical simulations of these experiments is given. New results from a numerical study of the stabilized combustion regime in this combustor are described. Several partially stirred reactor (PaSR) models for describing turbulent combustion are compared with a quasi-laminar approach. A model of variable turbulent Prandtl and Schmidt numbers is presented, and its influence on the reproduction of this flow in calculations is considered.

Изучался состав продуктов сгорания в воздухе при атмосферном давлении гипофосфита кальция Ca(H2PO2)2 c окислителями — нитратами либо нитритами натрия или калия. Синтез проводился с целью получить двойной фосфат состава Na(K)CaPO4. Готовились смеси порошков с нулевым кислородным балансом, для этого при необходимости вводили дополнительное количество нитрата аммония. Фазовый состав конденсированных продуктов сгорания исследовали методом рентгенофазового анализа. Смеси устойчиво горели при атмосферном давлении с выделением аэрозоля P4O10. Продукты сгорания представляли собой оплавленные частицы белого цвета размером до 1 мм. В конденсированных продуктах сгорания обнаружены двойные фосфаты NaCaPO4, Na2CaP2O7, K2CaP2O7, KCaPO4 и пирофосфаты кальция Ca2P2O7.

The composition of combustion products of calcium hypophosphite Ca(H2PO2)2 with sodium or potassium nitrates or nitrites as oxidizers in air at atmospheric pressure has been studied. Synthesis was carried out to obtain double phosphate of the composition Na(K)CaPO4. Mixtures of powders with zero oxygen balance were prepared using, if necessary, an additional amount of ammonium nitrate. The phase composition of condensed combustion products was studied by X-ray powder analysis. The mixtures burned stably at atmospheric pressure releasing P4O10 aerosol. The combustion products were melted white particles up to 1 mm in size. In condensed combustion products were found to contain the double phosphates NaCaPO4, Na2CaP2O7, K2CaP2O7, and KCaPO4 and calcium pyrophosphates Ca2P2O7.

Authors: Tóth Renátó , Resperger Viktória , Tóth László
Published: July 2024

This paper explores the integration of Rational Emotive Behavior Therapy (REBT) within sports psychology, aiming to enhance athletes' mental health and performance of athletes. Sports psychology, encompassing diverse approaches, prioritizes both the mental well-being and performance of athletes. REBT, a vital component of Cognitive Behavioral Therapy (CBT), revolves around an individual's beliefs influencing emotional, behavioral, and physiological reactions to events. It identifies and replaces irrational beliefs with rational alternatives, as depicted in the GABCDE model, emphasizing the impact of beliefs on reactions to triggering events. Previous research highlighted the detrimental impact of irrational beliefs on athletes' mental well-being, identifying these beliefs as a significant risk factor for the emergence of mental disorders, which in turn lead to compromised performance. The integration of REBT into sports psychology shows promise in reducing anxiety, perfectionism, and irrational beliefs among athletes. Its flexibility allows for swift and powerful interventions, either individually or in group settings, fostering mental resilience and enhancing performance. Sports psychologists and coaches play pivotal roles in recognizing and addressing athletes' irrational beliefs, fostering a rational mindset conducive to stable and positive performance. Integrating REBT into training and performance enhancement offers athletes a stable mental foundation, improving self-confidence and stress management, thereby optimizing sports performance. Overall, the integration of REBT into sports psychology offers a promising avenue to bolster athletes' mental fortitude, optimize performance, and foster a balanced mental landscape, facilitating the attainment of their athletic goals.

Published: July 2024

This study investigates the use of expressive speech acts in the motivational spoken word performances of Prince EA. Expressive speech acts, which convey the speaker's emotions and attitudes, play a crucial role in persuasive and motivational communication. The aim was to understand how Prince EA effectively engages and inspires his audience through these acts. A qualitative analysis was conducted on a selection of Prince EA's spoken word performances. Using speech act theory as a framework, instances of expressive speech acts were identified and categorized. Data was collected through transcription and thematic analysis of the videos. The analysis revealed a significant presence of expressive speech acts in these performances that cover apologizing, condoling, lamenting, showing attitude, agreeing, using exclamation, wishing, and thanking. These acts were predominantly expressing hope, encouragement, empathy, and personal conviction. The frequent use of these expressions contributed to the emotional resonance and motivational impact of the performances. The findings suggest that the effective use of expressive speech acts enhances the motivational appeal of Prince EA's spoken word performances. By conveying genuine emotions and attitudes, a connection with the audience is created, fostering a sense of empathy and inspiration. Hence, this study highlights the importance of expressive speech acts in motivational speaking and offers insights for speakers aiming to engage and motivate their audiences effectively.Keyword: pragmatic, ethics, speech acts, motivation
Sociocultural transitions of international employees
Authors: Min Jiyu
Published: July 2024

This study explores how engagement in informal communication and communicative interactions during lunchtime is a form of language socialization that contributes to the sociocultural transitions of international employees within the workplace. I conducted in-depth interviews with three international employees who had relocated from Japan to an American branch of a global automobile manufacturer headquartered in Japan, as well as field observations, audio-recordings, field notes and clarification emails. The findings revealed the crucial role of lunchtime communication in facilitating three distinct forms of transitional experiences among the participants: lateral, collateral and encompassing. Moreover, the study identified that different aspects of informal interactions with coworkers – including reflections on prior linguistic and cultural knowledge, self-awareness of English proficiency, negotiation of different cultural aspects and conflicts, nurturing social relationships and embracing new roles as mediators and experts – were linked to the promotion or hindrance of each transition. The findings underscore the significance of informal communication in the workplace during lunchtime in shaping the identity and membership development of international employees. By shedding light on this importance, the study provides valuable insights for multicultural companies seeking to support successful transitions and adaptation of their international workforce.
The efficacy of anterior cruciate ligament reconstruction and rehabilitation compared to conservative management for reducing the incidence of post-traumatic osteoarthritis following anterior cruciate ligament injury: A systematic review
Authors: McIntosh Catherine , O'Brien Daniel , Reid Duncan , Ellis Richard
Published: July 2024

Anterior cruciate ligament (ACL) injury is a risk factor for developing post-traumatic osteoarthritis (PTOA). The burden of ACL injuries and PTOA is considerable and predicted to increase if there is no change in their management. The efficacy of different ACL rehabilitation interventions in reducing the incidence of PTOA is unknown. This systematic review aimed to identify, synthesise, and critique research findings that evaluated the effectiveness of anterior cruciate ligament reconstruction (ACLR) plus rehabilitation compared to rehabilitation alone on the incidence of PTOA following ACL injury. A quality critique of the selected studies was undertaken using a modified Downs and Black appraisal tool. Data were extracted and analysed to answer the research question: What is the effect of ACL reconstruction and rehabilitation compared to conservative management on the incidence of PTOA after ACL injury? Six good-quality articles were retained for final review. Five studies compared the effect of surgical and non-surgical management of ACL injuries on developing PTOA. One study investigated the impact of different ACL rehabilitation protocols on the development of PTOA. The incidence of PTOA following ACL injury was comparable regardless of the surgical or non-surgical intervention and rehabilitation compared in each study. Further high-quality studies are needed to inform ACL injury management to reduce the impact of PTOA following ACL injury.
Does democracy reduce corruption? A cross-country causal counterfactual analysis
Authors: Viana Cristian Johan Picón , Boehm Frédéric
Published: July 2024

Abstract This paper examines the causal effect of the levels of democracy in countries on the levels of corruption. Research shows that the levels of corruption in countries decrease when they reach higher levels of democracy. However, most of the evidence has been obtained through correlational or regression studies that do not make clear the causal connection between the variables. The research applied a robust estimator (IPWRA) to a database of 161 countries with average data from 2010-2019, assessing a causality model within the counterfactual framework. The results indicate that a causal relationship does exist; that is, a higher level of democracy in the countries reduces the levels of corruption.
The Public Prosecutor’s Offices in Brazilian states: differences in autonomy and capacity
Authors: Rodrigues Rayane Vieira
Published: July 2024

Abstract The Brazilian Public Prosecutor’s Office is known for its autonomy and low levels of accountability. However, the literature has yet to explore the diversity among the Public Prosecutor’s Offices in Brazilian states, neglecting the territorial dimension in analyses and how different local political dynamics influence these organizations’ autonomy and capacity. Thus, this article aims to understand to what extent the Public Prosecutor’s Offices in Brazilian states differ in terms of their financial autonomy and capacity. The study employed mixed methods of analysis and proposes an autonomy and capacity indicator. The results unveiled significant diversity and considerable inequality among the offices. Furthermore, it was possible to observe how these differences reflect the territorial dimension and local political dynamics.

Campesinos en la universidad: entre la realidad de la educación básica en el campo y la lucha por la permanencia en la educación superior
Authors: Batista Ozaias Antonio , Silva Maria do Socorro Pereira da
Published: July 2024

Resumen Las Licenciaturas en Educación Rural se originan en las demandas históricas de los movimientos sociales campesinos por una educación que tenga en cuenta las realidades socioculturales campesinas. El estudio tiene como objetivo analizar la realidad socioeducativa de los estudiantes LEdoC de la UFPI/CPCE admitidos entre 2014 y 2018, situando la trayectoria de los campesinos en la educación básica rural, para comprender los desafíos de permanencia en la educación superior. En cuanto al método de investigación y análisis de los datos, se utilizó un enfoque cuantitativo-cualitativo, con énfasis en la investigación de tipo participante, ya que el campo de investigación es el mismo locus de actividad profesional de los investigadores. Para la recolección de datos se utilizaron técnicas de focus group realizadas con estudiantes, un cuestionario semiestructurado que se aplicó a los estudiantes matriculados en LEdoC. El método dialéctico guió el análisis de los datos en una combinación entre la realidad de los sujetos, el proceso histórico y sus contradicciones. Se concluyó afirmando que el proceso de negación del derecho a la educación a los campesinos por parte del Estado pone de relieve la necesidad de democratización de la universidad a través de una cultura académica que considere las especificidades socioculturales de los campesinos y la realidad de la educación básica en el campo en la dinámica de superar las desigualdades educativas, reducir el analfabetismo en el campo y ampliar la oferta, el acceso y la retención en la educación superior.

Published: July 2024

Abstract The surface runoff in agricultural areas can carry soil chemical elements, causing environmental and economic problems. Nutrient losses through surface runoff can occur in both particulate and dissolved forms, influenced by soil use and management systems. In this context, the objective of this study was to quantify the losses of N (NH4+ and NO3-), P, and K in dissolved and particulate forms in samples from a simulated rainfall event of 60 mm h-1 with a duration of 20 minutes, after the onset of surface runoff. The study was conducted in experimental plots in a randomized block design, with four treatments and two replications. The treatments were defined as T1 (fallow with spontaneous vegetation), T2 (irrigated rice under conventional tillage), T3 (no-tillage irrigated rice in monoculture), and T4 (no-tillage rice in crop rotation). The rainfall was applied in pre-seeding of irrigated rice, crop 2022/2023. The results showed that the highest losses of NH4+ and NO3- occurred in treatments T2 and T3 compared to the others. Regarding nutrient loss, treatments T1 and T2 showed the highest losses of P and K, with a greater presence in the soil fraction (particulate).

Published: July 2024

Abstract Water resource charges are fundamental for monitoring and planning effective actions to conserve, protect, and recover the Water Management Unit (UGRHI). The objective of this work was to analyze the monetary amount collected by the State of São Paulo from 2007 to 2019, considering 20 of the 22 UGRHI. It also aimed to simulate the uncollected amounts by employing three economic indices: the Fiscal Unit of the State of São Paulo (UFESP), the Broad Consumer Price Index (IPCA), and the General Price Index (IGP-M). The analysis indicates that the uncollected amount is between R$ 140 and R$ 170 million, depending on the index assessed, confirming the hypothesis that the adoption of an index would contribute significantly to water resource charges. The collected amounts are essential for investments in the Water Resource Policy of the State of São Paulo. It has not escaped the analysis that, until December 2020, there were still two UGHRI without any collection of charges.
Technologic protocol applied to medium size water supply systems aiming at water efficiency and loss reduction
Authors: Nogueira Felipe Pires , Silva Fernando das Graças Braga da
Published: July 2024

Abstract Water supply systems are basically composed of water intake, adduction, treatment, reservation and distribution, and in each component there is a variable amount of water and energy loss, which is present in any supply system. Water losses, which divides into real and apparent, occurs along the whole structure, focusing on water distribution networks because of the amount of connections that lead to bigger losses. Seeking to reduce these losses, procedures and techniques can be applied. This research aimed to propose an appropriate protocol to help managers of small and medium-sized water supply systems control and reduce their loss rates. To develop the protocol, the following steps were carried out: diagnosing the system, evaluating existing methodologies and proposing a protocol for this goal. The proposed protocol demonstrates an ability to adapt to the system’s demands and the managers’ capability to apply it, and can bring significant impacts with its application, leading to an improvement in water and energy efficiency in water systems.
Challenges of the family-school relationship in a Mapuche context: An approach from the teachers’ perspective
Authors: Arias-Ortega Katerin , Gajardo Mariela , Sierpe Juan , Santini Yislen
Published: July 2024

Abstract This research presents results on the meaning of school education from the perspective of the actors of the educational and social environment, namely, the teachers. The objective is to account for the challenges of the family-school relationship in an indigenous context, from the perspective of the teachers of two rural schools located in Mapuche communities of La Araucanía, a Southern region in Chile. The research problem states that the family-school relationship in a Mapuche context has historically been characterized by power relations that deny the involvement of the family members in the processes of intercultural school management. In this way, just nominal participation in administrative aspects is assumed. The methodology is qualitative with a descriptive scope, and the participants are six teachers. The data collection instrument is the semi-structured interview, and the data analysis technique is based on content analysis in complementarity with grounded theory. The main results show hegemonical powers that persist in the family-school relationship in the Mapuche context, marked by racism and discrimination. The main conclusions highlight the urgency of establishing continuous training on interculturality for schoolteachers working in Mapuche communities, which might allow reversing the hegemonical practices towards ‘the Mapuche’ present in the school. In this context, teacher training on interculturality would allow strengthening the educational relationship between the indigenous family and the school based on the incorporation of indigenous educational knowledge and skills, contributing to a school education with an intercultural perspective.

Published: July 2024

Resumen El artículo expone resultados de investigación sobre el sentido de la educación escolar desde la perspectiva de los actores del medio educativo y social. El objetivo es dar cuenta de los desafíos de la relación familia-escuela en contexto indígena, desde la perspectiva de los profesores de dos escuelas rurales situadas en comunidades mapuches de La Araucanía, Chile. El problema de investigación plantea que en la educación escolar en contexto mapuche la vinculación familia-escuela, históricamente, se ha caracterizado por relaciones de poder, que niegan la participación de la familia en los procesos de gestión escolar intercultural. De esta manera, se asume una participación funcionalista articulada a aspectos administrativos. La metodología es cualitativa con un nivel de alcance descriptivo, los participantes son seis profesores. El instrumento de recolección de información es la entrevista semidirigida, la técnica de análisis de la información es el análisis de contenido en complementariedad con la teoría fundamentada. Los principales resultados dan cuenta de relaciones de poder que persisten en la relación familia-escuela en contexto mapuche sustentados en una relación de racismo y discriminación. Las principales conclusiones relevan la urgencia de establecer una formación continua sobre interculturalidad para los actores del medio educativo, lo que permitiría revertir las prácticas discriminatorias hacia “lo mapuche” presentes en la escuela. Esto, en contexto mapuche permitiría fortalecer las relaciones educativas entre familia indígena y escuela con base en la incorporación de los saberes y conocimientos educativos indígenas, contribuyendo en una educación escolar en perspectiva intercultural.
Intersecções entre o pensamento freiriano e a psicanálise freudiana: uma revisão integrativa
Authors: Almeida William Xavier de , Martins Filho Lourival José
Published: July 2024

Resumo Este trabalho é uma revisão integrativa que visa levantar a produção bibliográfica em periódicos de artigos que explorem a intersecção entre o pensamento pedagógico de Paulo Freire e os arcabouços teóricos da psicanálise de Sigmund Freud. O levantamento ocorreu no segundo semestre do ano de 2022, em múltiplos repositórios, tanto os de caráter geral (Scientific Electronic Library Online/SciELO e Portal de Periódicos da Coordenação de Aperfeiçoamento de Pessoal de Nível Superior/CAPES), quanto as bases específicas das áreas da Educação (Associação Nacional de Pós-Graduação e Pesquisa em Educação/ANPEd e EDUC@) e da Psicologia (Portal de Periódicos Eletrônicos de Psicologia/PePSIC), a partir da combinação dos descritores “Freire” e “Freud” com o descritor “psicanálise”. Das centenas de documentos recuperados, após leitura e aplicação de critérios de exclusão, elegemos oito para compor o corpo de análise deste trabalho. As dificuldades e entraves no levantamento bibliográfico evidenciaram a carência de pesquisas sobre a interlocução entre estes autores, apesar de sua aparente fecundidade. O cotejamento dos escritos apontou similitudes entre as teorias dos dois autores, que convergem em pontos fulcrais de seus trabalhos. Conceitos freudianos como narcisismo, sadismo e masoquismo indicam processos psíquicos de colonização que podem manter os oprimidos em posição de passividade ou até de identificação perante o opressor. Entender estes mecanismos psíquicos por intermédio do corpo de conhecimento transdisciplinar que é a psicanálise pode oferecer bases para a compreensão e para a luta contra os grilhões físicos e psicológicos que acorrentam o oprimido.
Uma nova-velha história das ideias: pensamento educacional no I Congresso Brasileiro de História da Educação
Authors: Bontempi Jr. Bruno
Published: July 2024

Resumo Analisa as comunicações sobre pensamento educacional no I Congresso Brasileiro de História da Educação, realizado no Rio de Janeiro em 2000, e organizado pela Sociedade Brasileira de História da Educação. Considera-se que as reuniões científicas revelam conteúdos, cânones e modos de fazer de uma comunidade intelectual, assim como as posições e relações interpessoais e institucionais implicadas na produção do conhecimento. Relacionam-se os conteúdos das comunicações apresentadas nas sessões do subtema pensamento educacional a informações institucionais sobre as suas autorias, bem como sobre as práticas coetâneas da pesquisa na pós-graduação e as heranças disciplinares. Tendo como balizas a história daquele evento e da própria entidade organizadora, articulam-se as características majoritárias dessa produção às tradições disciplinares e vinculações de quem pesquisava e escrevia no lugar constituído sob o sistema nacional de pós-graduação. Esses elementos constituem a base empírica para a compreensão dos modos como este segmento dedicado ao pensamento educacional circunscrevia, operava e compartilhava noções e cânones. Conclui-se que as comunicações refletem a expansão regional das instituições, a nucleação de linhas e grupos de pesquisa, o predomínio das instituições públicas e o fomento governamental. O artigo coteja os resultados que estudos panorâmicos sobre o I CBHE interpretaram como efeitos de mudanças paradigmáticas, concluindo que as referências antagônicas não afetaram os modos e os resultados das abordagens no subtema, em que prevaleceu a tradição da história da pedagogia, longamente replicada em orientações e incorporada como um saber-fazer acadêmico generalizado.
Emoções e práticas docentes na inclusão escolar sob a perspectiva histórico-cultural
Authors: Faria Paula Maria Ferreira de , Camargo Denise de
Published: July 2024

Resumo O artigo relata uma pesquisa qualitativa fundamentada nos pressupostos da psicologia histórico-cultural, cujo objetivo foi compreender o processo de desenvolvimento das emoções e sua transformação nas práticas docentes inclusivas. Foram utilizadas entrevistas estruturadas, semiestruturadas e o dispositivo metodológico da autoconfrontação, interpretados por meio da análise microgenética vigotskiana. Participaram da pesquisa duas professoras de turmas inclusivas dos anos iniciais do Ensino Fundamental de uma escola pública brasileira. Identificou-se a dificuldade das professoras em expressar emoções e a ampla presença de emoções desagradáveis, com ênfase no adoecimento docente e na falta de apoio para a inclusão escolar. Evidenciou-se a dificuldade das professoras em expressar e referirem-se às próprias emoções, reverberando o modelo cartesiano que relega as emoções em detrimento da cognição. Embora tenham sido mencionadas emoções como amor/gostar e esperança, os resultados revelaram a ampla presença de emoções desagradáveis (angústia; desamparo, aflição, impotência; frustração; incapacidade, insegurança; incompletude; sentir-se mal; tristeza). Por meio da pesquisa, as docentes participantes puderam reconhecer e refletir sobre suas emoções/práticas inclusivas que se amalgamam no cotidiano da escola, (re)conhecendo suas emoções/práticas e configurando novos sentidos às suas vivências. Conclui-se que a entrevista de autoconfrontação permitiu que as participantes refletissem sobre suas emoções e práticas inclusivas, contribuindo para a tomada de consciência e para a transformação do trabalho das docentes por meio do aumento do poder de agir sobre a própria atividade.
Anthropocene Fantasy and Infrastructures of Exploitation
Authors: Carroll Siobhan Maria , Larkin Edward
Published: July 2024

This essay traces the emergence of Anthropocene fantasy through an analysis of three multivolume series—George R. R. Martin's A Song of Ice and Fire, Robin Hobb's Realm of the Elderlings, and N. K. Jemisin's The Broken Earth. Each of these series repurposes the conventions of epic fantasy to analyze the ideological underpinnings of anthropogenic crisis. Among the most important tropes revised are fantasy infrastructures, which, in Anthropocene fantasy, frequently manifest a problematic division between the human and the nonhuman. Consequently, characters’ responses to these infrastructures often reflect these novels’ ecological politics. The surrender of agency associated with the abandonment of ancient infrastructures further indicates Anthropocene fantasy's interest in reimagining the individualistic mode of human agency that drives so many novel plotlines, fantasy and realist alike. Anthropocene fantasy's revision of its own problematic genre infrastructures thus has implications not only for the epic fantasy but for the novel form more broadly.
Ephemeral Improvement: Interactive Print and the Material Texts of Early Abolitionism
Authors: King Rachael Scarborough
Published: July 2024

This article argues that a reliance on material texts tied to the concept of improvement—such as picturesque engravings, diagrams, and account books—pushed the early abolitionist movement toward a reforming, ameliorationist ethic that disavowed revolutionary action and immediate emancipation. Although the term improvement had broad social applicability by the late eighteenth century, its original connections to land management made it an especially important concept for the abolitionist debate. Integrating book history with studies of enslavement and abolition, I show how abolitionists’ use of visual-textual forms such as diagrams and account books created an emphasis on gradual improvement. In response, Black abolitionists both emphasized concepts other than improvement and presented their works in different material forms. Olaudah Equiano and Quobna Ottabah Cugoano adapted the genre of autobiography to demonstrate how their own ostensible improvements did not have the effects anticipated by the logic of white abolitionists, ultimately undercutting the usefulness of improvement as a guiding concept for abolitionism.
«Clean Off or Get Out». (Self)Governance, Community and Citizenship in New Large Housing Estates in Russian Cities
Authors: Chernysheva Liubov
Published: July 2024

The article presents an analysis of the (self)management of the newly constructed large housing estate “Severnaya Dolina” (St. Petersburg, Russia). Built within the neoliberalization of Russian housing policy, this housing estate is an urban space where intervention and control by the state is limited, the provision of social goods is partially shifted to a private development company that manages the territory, and social control is mostly exercised by residents. I analyze this situation as an example of neoliberal communitarianism, or a governance model based on community mobilization, responsibilization of citizens, and an emphasis on the notion of “active citizenship”. In contrast to existing approaches to the analysis of neoliberal communitarianism and responsibilization as programs initiated by governments, I consider its «real existence» in the practices of the inhabitants of the new LHE. Referring to the materials of the focus groups conducted, as well as the analysis of the online communication of the residents of “Severnaya Dolina”, I demonstrate, firstly, what ideas they have formed about the management of the territory of the district, focusing on the distribution of responsibility for solving problems and especially the role that the residents assign to themselves. Secondly, I demonstrate how elements of neoliberal communitarianism are manifested: these are practices of management arising beyond the state, as well as responsibilization of the residents and the formation of a version of urban citizenship. To describe these elements (not provided top-down within a state/city campaign but deriving down-up from the local practice), I propose the notion of “violent neighborness,” which reflects the radical form of responsibilization that residents exercise towards each other, as well as the concept of local urban citizenship, which captures the connection between the inhabitants of the “Severnaya Dolina”, local community, and territory.
