Authors: Pînzariu Sorin
Published: June 2021

The field of campaign services is currently the most complex area of logistical support, as it covers a wide range of services, requires cooperation between military bodies and various institutions, entities involved in providing them and requests promptness from planning and logistics management bodies in immediately solving the various problems that may arise. I set out to make an “radiography” of this complex field of logistics aiming to identify its general aspects in the processes of organization and assurance, as they manifest themselves at the level of a tactical unit
A Statistical Evaluation of The Depth of Inheritance Tree Metric for Open-Source Applications Developed in Java
Authors: Prykhodko Sergiy , Prykhodko Natalia , Smykodub Tetyana
Published: June 2021

The Depth of Inheritance Tree (DIT) metric, along with other ones, is used for estimating some quality indicators of software systems, including open-source applications (apps). In cases involving multiple inheritances, at a class level, the DIT metric is the maximum length from the node to the root of the tree. At an application (app) level, this metric defines the corresponding average length per class. It is known, at a class level, a DIT value between 2 and 5 is good. At an app level, similar recommended values for the DIT metric are not known. To find the recommended values for the DIT mean of an app we have proposed to use the confidence and prediction intervals. A DIT mean value of an app from the confidence interval is good since this interval indicates how reliable the estimate is for the DIT mean values of all apps used for estimating the interval. A DIT mean value higher than an upper bound of prediction interval may indicate that some classes have a large number of the inheritance levels from the object hierarchy top. What constitutes greater app design complexity as more classes are involved. We have estimated the confidence and prediction intervals of the DIT mean using normalizing transformations for the data sample from 101 open-source apps developed in Java hosted on GitHub for the 0.05 significance level.
Knowledge and Circulation of Plants: Unveiling the Participation of Amazonian Indigenous Peoples in the Construction of Eighteenth and Nineteenth Century Botany
Authors: Sanjad Nelson , Pataca Ermelinda , Santos Rafael Rogério Nascimento dos
Published: June 2021

This article gives visibility to Amazonian indigenous peoples in the global process of plant circulation and associated knowledge. The first part highlights the indigenous role in cultivating and collecting native plants, and in the processing of natural products over the second half of the eighteenth century. The second part shows that these activities were influenced by internal colonial dynamics, as well as by international relations. The case of the ayapana herb is analysed in detail. This plant became known worldwide at the beginning of the nineteenth century thanks to the interactions among indigenous knowledge, Portuguese colonial politics and the performance of military and naturalists of different nationalities. Examples like this show that, in the process of building botany, which occurred concurrently with the globalization of plants, indigenous peoples provided not only specimens that circulated around the world, but also knowledge related to cultivation, transportation and uses.

Traditional Segregation: Encoded Language as Powerful Tool. Insights from Okǝti Ụmụakpo-Lejja Ọmaba chant
Authors: Madu Uchechukwu E.
Published: June 2021

Language becomes a tool for power and segregation when it functions as a social divider among individuals. Language creates a division between the educated and uneducated, an indigene and non-indigene of a place; an initiate and uninitiated member of a sect. Focusing on the opposition between expressions and their meanings, this study examines Ụmụakpo-Lejja Okǝti Ọmaba chant, which is a heroic and masculine performance that takes place in the Okǝti (masking enclosure of the deity) of Umuakpo village square in Lejja town of Enugu State, Nigeria. The mystified language promotes discrimination among initiates, non-initiates, and women. Ọmaba is a popular fertility Deity among the Nsukka-Igbo extraction and Egara Ọmaba (Ọmaba chant) generally applies to the various chants performed to honour the deity during its periodical stay on earth. Using Schleiermacher’s Literary Hermeneutics Approach of the methodical practice of interpretation, the metaphorical language of the performance is interpreted to reveal the thoughts and the ideology behind the performance in totality. Among the Findings is that the textual language of Ụmụakpo-Lejja Okǝti Ọmaba chant is almost impossible without authorial and member’s interpretation and therefore, they are capable of initiating discriminatory perception of a non-initiate as a weakling or a woman.
The preventive role of Spirulina platensis (Arthrospira platensis) in immune and oxidative insults in a stress-induced rat model
Authors: Seyidoğlu Nilay , Köşeli Eda , Gurbanlı Rovshan , Aydın Cenk
Published: June 2021

Introduction

There is a balance between oxidative stress, antioxidant capacity and immune response. Their roles in physiological and behavioural mechanisms are important for the maintenance of the organism’s internal equilibrium. This study aimed to evaluate the antioxidant effects of the exogenous alga Spirulina platensis (Arthrospira platensis) in a stress-induced rat model, and to describe its possible mechanism of action.

Material and Methods

Thirty-six adult male Sprague Dawley rats were separated into four groups: control (C), stress (S), S. platensis (Sp), and S. platensis + stress (SpS). The rats in groups Sp and SpS were fed with 1,500 mg/kg b.w./day Spirulina platensis for 28 days. All rats were exposed to prolonged light phase conditions (18 h light : 6 h dark) for 14 days. The SpS and S groups were exposed to stress by being kept isolated and in a crowded environment. Blood samples were obtained by puncturing the heart on the 28th day. The effect of stress on serum corticosterone, oxidative stress markers (TOS, TAC, PON1, OSI) and immunological parameters (IL-2, IL-4, IFN-ɣ) were tested. Also, the brain, heart, intestines (duodenum, ileum, and colon), kidney, liver, spleen, and stomach of the rats were weighed.

Results

Serum corticosterone levels were higher in the S group than in the C group, and significantly lower in the SpS group than in the S group. Mean total antioxidant capacity were lower in the S group than in the C group, and Spirulina reversed this change. Although not significantly different, IL-2 was lower in the S group than in the C group. However, in the SpS group, IL-2 increased due to Spirulina platensis mitigating effects of stress.

Conclusion

Male rats fed a diet with Spirulina platensis could experience significantly milder physiological changes during stress, although stress patterns may be different. Exogenous antioxidant supplements merit further investigation in animals and humans where the endogenous defence mechanism against stress may not be sufficient.
Agree, Move and the Scope of the Phase Impenetrability Condition
Authors: Witkoś Jacek
Published: June 2021

This paper addresses a certain contradiction in the application of the Phase Impenetrability Condition (PIC) to domains involving the long-distance Genitive of Negation (GoN) and wh-movement in Polish. It appears that in syntactic domains of the tensed sentence including an infinitive complement, there is a tension between a long-distance dependency (holding between NEG in the main clause and the embedded object in genitive) and a cyclic operation of wh-movement. The operation of wh-movement, a classic example of Chomsky’s Move, observes cyclicity and the PIC, judging by the standard tests based on reconstruction (Chomsky 1995; Heycock 1995; Fox 1999; Safir 1999; Legate 2003; Witkoś 2003; Lebeaux 2009), while the Agree-based case marking requires the PIC to be inoperative in exactly the same context and in the same domain. Both operations place contradictory requirements on the PIC, which implies that this condition does not apply to them in the same manner: it always holds of Move but does not always hold of Agree.
Stance complement clauses controlled by verbs in academic research papers
Authors: Kozáčiková Zuzana
Published: June 2021

This paper explores stance complement clauses in the genre of academic discourse, analysing stance complement clauses controlled by verbs in economics research articles written in English by non-native writers. Following Biber’s taxonomy (2006) of common lexico-grammatical features used for stance analyses, the results of the study show that epistemic verbs of certainty and likelihood are an important means of communicating knowledge in this genre and thus, form an inseparable part of academic research writing. Moreover, the study seeks to analyse the contrast between stance to-infinitives and stance that-clauses in the studied corpus. While stance that-clauses relate mainly to the category of certainty; on the contrary, stance to-infinitive clauses are consciously or subconsciously chosen to lessen the risk of a face-threatening act and typically refer to writers’ sensory experience (e.g. verbs such as seem, appear, etc.). The findings suggest that research papers from the field of economics demonstrate a clear preference for factive verbs over non-factive verbs.
Gender identities in e-shop perfume descriptions
Authors: Nemčoková Katarína , Kráľová Zdena , Holíková Aneta , Sampey Daniel P.
Published: June 2021

Perfume descriptions serve as an important persuasive tool in fragrance advertising. Scents traditionally elude clear verbal description, yet perfumes are nowadays frequently sold online, with no direct olfactory experience on the part of the consumer at the point of purchase. The products are thus often represented by metaphorical means depicting a desirable experience or portraying attractive identities of wearers, including stereotypical images of men and women. This article analyses 80 e-shop fragrance descriptions equally divided among adverts targeted at males and females. The sample texts were collected randomly from British and American e-shops, with the primary research objective to determine how male and female identities are reflected in these descriptions. The method of discourse analysis was applied and the AntConc 3.4.4 toolkit was used to calculate the frequency of words and their collocations. It was found that current female perfume descriptions on e-shops generally suppress gender stereotypes quite successfully, while gender stereotyping is more prominent in male perfume descriptions. The possible causes as well as ramifications of this disparity are also discussed.
‘Sorry, i don’t want them here.’ Migration in Slovak Political Discourse
Authors: Štefančík R. , Kiner A.
Published: June 2021

The issue of international migration in Slovakia was not a topic of public discussion until 2015. A major change in migration discourse can be observed only after the mass migratory processes in 2015, a few weeks before the Slovak parliamentary elections. Just before the elections, politicians had also noticed these processes, putting the spotlight on migration, which became a frequent priority topic of electoral campaigns for several weeks. Our aim with this paper is to answer a question of how Slovak politicians, who had ignored this topic for many years, dealt with the issue of international migration since 2015 and which aspect dominated the emerging migration discourse. We came to the conclusion that Slovak politicians tackled the issue almost uniformly, regardless of their ideological beliefs or coalition-opposition framework. Most politicians presented migration as a threat. In addition to the securitization of migration discourse, we also observe a gradual shift in the understanding of the term migrant. Until 2015, the naming of the particular actor of migration processes was generally understood to be neutral, yet since 2015 the term has acquired a strong negative connotation.
Literature as a Source of Metaphorical Modeling in Russian Media Discourse
Authors: Krajčovičová L.
Published: June 2021

The goal of this article is to analyze the principles and methods of using the precedent semantics of literary onyms in the process of metaphorization of the high-profile international event Brexit in contemporary (2016–2021) Russian-language media discourse. The research material encompasses media discourse, from which fragments of online versions of Russian-language newspaper and journalistic texts of different genres and socio-political orientation have been selected. As an additional source of empirical material, the author uses the newspaper subcorpus of the national corpus of the Russian language, as well as the Russian-language subcorpus of the international databases Eastview and Aranea. In order to achieve the main goal of the research the author uses the method of continuous sampling, methods of corpus linguistics, methods of content analysis, as well as narrative and contextual analysis (of fragments of media discourse), linguocultural analysis of texts, methods of conceptual analysis and interpretation. Thanks to the use of methods of corpus linguistics, more than 400 contextual realizations of the use of precedent names in connotative metaphorical meaning (in connection with Brexit) have been collected and analyzed. The article presents only the most expressive and most common examples of metaphorization of precedent names when describing the discursive event of Brexit. On the basis of the analysis, the author concludes that the so-called universal-precedent phenomena (mainly of English but also European literature) prevail in the process of metaphorization compared to those of Russian literature, which are extremely rare. In the paper’s study, the author also focuses on the fact that precedent names in the process of metaphorization undergo desemanticization (simplification of the meaning) and become distinctive cultural stereotypes. Initial hypothesis that the intertextuality of the Russian media discourse has a pronounced literary-centric character is confirmed.

Azerbaijan-Venezuela relations

Published: June 2021

The object of this collaborative study is the evolution of Azerbaijan-Venezuela relations since the moment of their establishment in 1995 till the present day. The purpose of the article is to define the main stages of development of bilateral relations between Azerbaijan and Venezuela, detect the potential prospects of their development, denote areas of common interest in the global agenda, and study the source base of bilateral relations. Using the case study method, the authors not only analyze the actions of both parties aimed at the development of bilateral relations, but also predict the official strategy of Baku and Caracas of further advancement of the interstate dialogue. The authors arrive at a conclusion that the geopolitical grounds of Azerbaijan’s foreign policy have been influenced by its defeat in the First Karabakh War (1992 - 1994) and the occupation of 20% of its territory by the Armenian armed forces. In subsequent years, all foreign policy maneuvers of official Baku were reduced to one goal: to restore its territorial integrity. That was the reason for Baku’s aspiration to garner the support of other states. In this direction, the most fruitful one was the work of Azerbaijan diplomacy in Latin American countries including Venezuela. Notably, official Baku and Caracas have similar stands on many issues of global and domestic policy. For Venezuelan President Nicolas Maduro, close connections with Azerbaijan is an additional proof of his legitimacy in political in-fighting against the opposition. The scientific novelty of the research consists in the fact that it is one of the first attempts to analyze Azerbaijan-Venezuela relations from a comprehensive perspective.

Molecular modeling of lipids has been hampered by the size of these complex, biologically important molecules. Yet, understanding the structure and energy (enthalpy) of large molecules is critical to identifying their function in chemical equilibrium and transition state theory. In this work, we use both experimental data and G4 computed results, to show that cis polyunsaturated lipids have helical conformers. We present linear functions for the enthalpy of formation ΔfH°298 and the Gibbs free energy of formation ΔfG°298 as a function of n, where n is the number of carbon atoms in a linear carboxylic acid chain. Taking ΔfH°298 of a saturated acid as a starting point, we add the enthalpy of hydrogenation ΔhydH°298 at appropriate locations on the carbon chain to model polyunsaturated fatty acids. For example, taking eicosanoic acid (C20) as a saturated starting point, we add four enthalpies of cis-dehydrogenation (ΔhydH°298) to obtain arachidonic acid (eicosa-5Z,8Z,11Z,14Z-tetraenoic acid). We compare Gaussian-4 computational results, to show evidence of helical structure. We conclude that fatty acids can have helical conformers facilitating a broad range of biological functions.

The efficiency of regenerative heat exchangers with heat storage nozzles made of rolled corrugated tapes depends on the type of their corrugation profile. The most effective form is a triangular one with sharp peaks and troughs. It is technically advisable to get corrugations of a given shape by rolling between two rollers. Determining the required contact load and forces is one of the main tasks when rolling corrugated belts. Insufficient load leads to incomplete formation of the profile, and excessive load leads to warping of the belt. The article presents the results of an experimental study aimed at determining the required load when rolling a corrugated heat exchanger belt for wind tunnels. Experiments and force measurements are carried out on a standard milling machine with a spring dynamometer. The results of the experiment are applied to stainless steel strips with a thickness of 0,3 to 0,4 mm and triangular fluting

Reduction of technological losses of natural gas during production, transportation and storage is of major energy and environmental importance. Losses of natural gas are the target for active criticism by «green energy» representatives. It is necessary to develop and popularize the new technological solutions aimed at reducing the indirect impact on the environment associated with the production and use of liquefied natural gas, to demonstrate the readiness of specialists of this energy sector to take into account modern social preferences. The article presents the numerical analysis of the energy efficiency for one of the stages of large-scale LNG production, namely, the LNG delivery from a storage tank to a LNG carrier vessel via a cryogenic pipeline. The mathematical model of the thermal enclosure of the pipeline has been considered, and the production cryoproduct losses due to thermal inertia of pipeline materials have been estimated. The performance of the schemes recommended for utilization of LNG vapors has been evaluated
Estimation of multi-layer coating efficiency for passive radiative cooling
Authors:   ITMO University, Jenblat S. S. , Volkova O. V. ,   ITMO University
Published: June 2021

Passive radiative cooling is a promising direction in energy conservation and environmental protection. One of the ways to increase the efficiency of radiative cooling systems is the use of multi-layer coatings. In recent years, several novel materials with high emissivity have been proposed, which allow the creation of radiators that provide an average daily cooling power of approximately 100 W/m2 during daytime. Based on the developed mathematical model, the optical properties of the multi-layer coating for the radiative cooling system were evaluated by the Transfer Matrix Method and the effectiveness of radiative cooling was determined due to the use of the multi-layer coating in the climatic conditions of Syria (Latakia). The results of modeling the atmospheric transmittance in the summer months in Syria (Latakia) are presented. The developed mathematical model, methods for modeling atmospheric transmittance, calculating solar radiation, and evaluating the optical properties of multi-layer coating, allow determining an effective multi-layer coating for radiative cooling systems in any climatic conditions

Published: June 2021

The use of transcritical R744 systems has become increasingly popular in recent years in a variety of different applications. For applications that span a wide temperature range between the heat source and heat sink, the use of two-stage compressor results in numerous advantages in terms of efficiency and compressor discharge temperature. This paper presents experimental data for a transcritical R744 compressor system operating at high heat rejection temperatures. A comprehensive system model was developed and validated with the experimental results. Based on this, the simulation tool was used to further optimize the system design specifically to accommodate the two-stage compression process. The optimum heat transfer area distribution has been determined to simultaneously ensure efficient intercooling at intermediate pressure and gas cooling at the high-pressure level. Simultaneously, the system was also optimized with respect to optimal intermediate pressure and the results show that for this particular system, the optimum intercooler pressure deviated substantially from the standard design approach that uses the geometric mean between suction and discharge pressures

A study of the cycles of a lithium bromide–water absorption chiller with two-stage absorption and three-stage generation of a working substance vapor with an associated mass flow with different supply of the cooling medium to the apparatus has been carried out. The temperature of the heating source necessary for the implementation of the actual thermodynamic cycle of the Lithium Bromide– Water Absorption Chiller (LBWAC) and the most effective thermodynamic cycle has been determined. A comparative analysis of the cycle understudy with the sample cycle (one-stage cycle) LBWAC is carried out. Despite the lower values of the coefficient of performance (COP), the cycle under study provides a doubling of the cooling capacity of the machine, at the same flow rate of the heating source, which is an advantage when the flow rate of the heating source is limited. This circumstance is explained by the fact that in LBWAC with multi-stage absorption and generation, the heating source sequentially passes through three generator stages. Therefore, the degree of cooling in the chiller with the considered cycle is three times higher than this value of a single-stage LBWAC

Members of the protein kinase D (PKD) family (PKD1, 2, and 3) integrate hormonal and nutritional inputs to regulate complex cellular metabolism. Despite the fact that a number of functions have been annotated to particular PKDs, their molecular targets are relatively poorly explored. PKD3 promotes insulin sensitivity and suppresses lipogenesis in the liver of animals fed a high-fat diet. However, its substrates are largely unknown. Here we applied proteomic approaches to determine PKD3 targets. We identified more than 300 putative targets of PKD3. Furthermore, biochemical analysis revealed that PKD3 regulates cAMP-dependent PKA activity, a master regulator of the hepatic response to glucagon and fasting. PKA regulates glucose, lipid, and amino acid metabolism in the liver, by targeting key enzymes in the respective processes. Among them the PKA targets phenylalanine hydroxylase (PAH) catalyzes the conversion of phenylalanine to tyrosine. Consistently, we showed that PKD3 is activated by glucagon and promotes glucose and tyrosine levels in hepatocytes. Therefore, our data indicate that PKD3 might play a role in the hepatic response to glucagon.

Sepsis, sequela of bloodstream infections and dysregulated host responses, is a leading cause of death globally. Neutrophils tightly regulate responses to pathogens to prevent organ damage. Profiling early host epigenetic responses in neutrophils may aid in disease recognition. We performed assay for transposase-accessible chromatin (ATAC)-seq of human neutrophils challenged with six toll-like receptor ligands and two organisms; and RNA-seq after Escherichia coli exposure for 1 and 4 h along with ATAC-seq. ATAC-seq of neutrophils facilitates detection of pathogen DNA. In addition, despite similarities in genomic distribution of differential chromatin changes across challenges, only a fraction overlaps between the challenges. Ligands depict shared signatures, but majority are unique in position, function, and challenge. Epigenomic changes are plastic, only ∼120 are shared by E. coli challenges over time, resulting in varied differential genes and associated processes. We identify three classes of gene regulation, chromatin access changes in the promoter; changes in the promoter and distal enhancers; and controlling expression through changes solely in distal enhancers. These and transcription factor footprinting reveal timely and challenge specific mechanisms of transcriptional regulation in neutrophils.

Authors: Sampaio Leila Silvia , Silva Rosana Rodrigues da
Published: June 2021

Este trabalho objetiva discutir o ensino da literatura indígena, partindo do aporte teórico e metodológico que vem se abrindo para o conhecimento a favor da prática no ensino. A pesquisa bibliográfica revela que, atualmente, tem-se a preocupação com a discussão do tema que vem se expandido nos centros acadêmicos. As pesquisadoras Janice Thiél (2012), Graça Graúna (2013), Sueli de Souza Cagnetti e Alcione Pauli (2015) apresentam estudos acerca da literatura indígena, propostas de formação profissional e prática em sala de aula, com o intuito de levar conhecimento ao acerca do contexto da produção de literatura indígena para que a prática se efetiva ao encontro do objetivo literário, formar leitores mais críticos e aproximar as diferenças com a promoção do respeito. A fim de exemplificar possibilidades de estudo, o artigo apresenta a obra As fabulosas fábulas de Iauraetê (2007) do autor Kaká Werá Jecupé que compõe excelente material de auxílio no ensino e aprendizagem dessa literatura. Adquirir conhecimento a respeito da literatura indígena é relevante para que as práticas de ensino com as obras literárias dessa autoria sejam exploradas de maneira que favoreça seus objetivos.

Authors: Souza Flávia Roberta Menezes de
Published: June 2021

O presente artigo apresenta a leitura da crítica sobre o romance Os Habitantes (1976) de Dalcídio Jurandir (1909-1979) no tempo de seu lançamento e relaciona essa primeira leitura a uma nova proposta de leitura do romance, embasada na teoria da narrativa de Gérard Genette e na teoria do romance polifônico de Mikhail Bakhtin.
A ESCURIDÃO E A MADRESSILVA: MANIFESTAÇÕES LÍRICAS NA NARRATIVA DE QUENTIN COMPSON EM O SOM E A FÚRIA, DE WILLIAM FAULKNER
Authors: Silva Claudimar Pereira da
Published: June 2021

O presente artigo objetiva a análise da narrativa de Quentin Compson, no romance O som e a fúria (2004), do escritor americano William Faulkner, no que tange Ã s teorias da narrativa poética propostas por Jean-Yves Tadié (1978) e Ralph Freedman (1971). Assim, pretende-se analisar o modo como estrutura-se a voz lírica de Quentin, por meio das técnicas de fluxo de consciência e monólogo interior, pela verticalização sintática, pela projeção lírica do narrador nos espaços e pelo recurso Ã s imagens, símbolos e metáforas, articuladas Ã  diegese.
ORGULHO E PRECONCEITO E A MILÍCIA
Authors: Faria Marcella de Melo
Published: June 2021

O presente artigo tem como finalidade identificar e analisar no romance Orgulho e Preconceito de Jane Austen, publicado em 1813, elementos do ambiente histórico, político e social da época, desencadeados pelos acontecimentos relacionados Ã  milícia inglesa. Para tanto, descreveu-se brevemente o contexto das guerras napoleônicas e adotou-se, como linha de pensamento teórico, os pressupostos do New Historicism, associados metodologicamente Ã s bases da análise de conteúdo. O resultado permitiu concluir que Austen, diferente da característica atribuída a sua obra pela crítica - “escrita para mocinhas” - também escreveu sobre a política de sua época, como demonstrou no romance enfocado neste estudo.
O FEMINISMO NA LITERATURA: A IMPORTÃ‚NCIA DA VISIBILIDADE DA MULHER NO ENSINO DE LITERATURA NA EDUCAÇÃO BÁSICA ATRAVÉS DO TEXTO COMPANHEIRAS DE ENEIDA DE MORAES
Authors: Neves Jesssica Carolina de Souza , De Souza Luana Beatriz Rodrigues , Requena Pamella Cristina
Published: June 2021

O presente trabalho tem por objetivo apresentar uma prática docente de letramento literário por meio da crônica Companheiras, da escritora Eneida de Moraes, com a aplicação da sequência básica proposta por Rildo Cosson (2014) e das propostas da interação com o texto literário. Especificamente, o foco da pesquisa-bibliográfica de cunho qualitativo consiste em uma proposta de aplicação de um projeto de leitura para turmas de Ensino Médio. Com intuito de mostrar a relevância da autoria e do protagonismo feminino nos estudos de literatura na educação básica, objetivando sistematizar prática de leitura motivacional que gere resultados satisfatórios quanto Ã  interpretação da obra literária. Visto que o primeiro contato no que tange ao desenvolvimento do indivíduo como leitor, na maioria das vezes, ocorre nas escolas. Ainda sob o ponto de vista teórico, busca-se entender as vozes das mulheres na literatura e trazer práticas de leitura segundo os estudos de Duarte (2003), Cosson (2014), Hollanda (1993),Cândido (1989)e em que medida o trabalho com o texto literário pode corroborar na aquisição de múltiplas linguagens pelos discentes. O poder humanizador que o texto literário possui sobre o indivíduo.Por fim, buscou-se promover uma sequência didática humanizada, com vozes femininas, dialogando com os estudos culturais.

O PERIGO DA MULHER ÚNICA: REFLEXÕES SOBRE A IDEIA DE FEMININO EM A HISTORIADORA OBSTINADA, DE CHIMAMANDA NGOZI ADICHIE
Authors: Castro de Oliveira Maria de Jesus
Published: June 2021

Este trabalho tem por objetivo ressaltar algumas das ideias propostas pela escritora nigeriana Chimamanda Ngozi Adichie em duas conferências suas e relacioná-las com a concepção de mulher em seu sentido europeu e pós-colonial, postas, a partir das observações pontuais da própria escritora quanto Ã s semelhanças e diferenças entre o feminino nas duas concepções. Adiante, analisamos o conto “A historiadora obstinada”, da mesma autora e apontamos os elementos que contribuem para assinalar a ideia de mulher no contexto africano, mais precisamente nigeriano, e como essa mulher possui traços próprios, que revelam uma experiência peculiar de algum modo similar Ã  mulher europeia e distinta em relação Ã  mesma, tomando como base a contribuição teórica de Elizabeth Badinter, Joan Scott e Gayatri C. Spivak. Por fim, sugerimos como o conto problematiza a situação da mulher no contexto pós-colonial e como essa mulher se coloca numa posição paradoxal, entre a permanência no lugar de origem e a sua saída desse espaço cultural.
An Evolutionary Cognitive Approach to Comparative Fascist Studies: Hypermasculinization, Supernormal Stimuli, and Conspirational Beliefs
Authors: Ambasciano Leonardo
Published: June 2021

After summarizing Roger Griffin’s Fascism: An Introduction to Comparative Fascist Studies (2018), I describe the academic subfield of Comparative Fascist Studies (CFS). I argue that CFS could be strengthened by integrating it with cognitive science, evolutionary psychol­ogy, and religious studies. That biocultural integration would make it more effective as both a scholarly endeavour and an antifascist vaccine for democratic societies. I explain the role of traditional mass media and digital social media in the rise of dominance-style leadership and radical-right populism, construct a neurosociological revision of the CFS concept of fascism as a “political religion,” and characterize ultranationalism as a set of maladaptive supernormal stimuli. These revisions of CFS aim at providing a cross-disciplinary frame­work able to explain the spread of alt-right conspiracy theories online and offline.
Imagination in the Generation of Pictures and Interpersonal Scenarios
Authors: Oatley Keith
Published: June 2021

In Imagination, Jim Davies explains that most humans have mental imagery: an ability to make pictures in the mind without immediate perceptual input-as we do when we dream. Davies writes programs that enable computers to do something similar. Given a few words of description, a computer can generate pictures with several objects arranged in appropriate ways. Jonathan Gilmore’s Apt Imaginings is about whether engagement in works of fiction is continuous or discontinuous with how we deal with people and objects in everyday life. He argues for discontinuity. In constructing a critical framework within which to evaluate these two books, I use Kenneth Craik’s theory of mental models. Craik’s theory enables us to understand how we humans have evolved to imagine possible futures, to plan and to act in relation to them, and also to imagine what might be going on in other people’s minds.
