Особенности сделок слияний и поглощений инновационных компаний на развитых и развивающихся рынках капитала
Authors: Скворцова Ирина Вячеславовна , Красовицкий Андрей Дмитриевич
Published: December 2018

В настоящее время инновационные компании являются одним из ключевых драйверов мирового рынка слияний и поглощений, что обусловливает актуальность выявления их особенностей, а также исследования вопросов эффективности подобных сделок. Вместе с тем в современной академической литературе отсутствует однозначные ответы на вопросы о том, какую компанию можно считать инновационной, каким образом определить уровень ее инновационности, что такое инновационная сделка по слиянию и поглощению и какими особенностями она обладает. Крайне мало внимания уделяется международным инновационным сделкам по слияниям и поглощениям и определению их особенностей. В данной статье приводится краткий обзор имеющейся литературы на данную тему. Описываются способы определения инновационной компании и основные подходы для оценки эффективности инновационных сделок по слияниям и поглощениям. Рассматриваются также международные инновационные сделки по слияниям и поглощениям и их особенности. По результатам проведенного обзора был получен вывод о том, что в большинстве работ инновационность определяется через абсолютную величину различных показателей, список которых приводится в данной статье, или с помощью специальных опросников, которые направляются менеджменту компании. Инновационные компании также могут быть определены исходя из отраслей, в которых задействованы компании. Для определения эффективности инновационных сделок по слияниям и поглощениям, как правило, используются показатели, связанные с приростом или цитируемостью имеющихся патентов у компании. Однозначного ответа на вопрос о влиянии сделок по слияниям и поглощениям на инновационную активность компании дать не удалось, так как результаты исследований имеют противоречивый характер. Основным же мотивом международных инновационных сделок по слияниям и поглощениям является приобретение новых технологий для получения конкурентных преимуществ. Тем не менее полное представление  об эффективности данного типа сделок отсутствует.
Simulation of Buffered Advection Diffusion of Calcium in a Hepatocyte Cell
Authors: Jagtap Y.D. , Adlakha N.
Published: December 2018

The calcium signaling is the basic and vital component of cell communication in almost all types of human and animal cells. All the vital functions of parenchymal cell of liver known as hepatocyte cell are regulated by this calcium signaling. The calcium concentration at specific levels are responsible for each of the various functions of the cell. The deeper understanding of the mechanisms and the factors affecting the calcium dynamics in a hepatocyte cell is vital for various clinical applications related to diseases of the liver. In this paper, mathematical model is proposed to study intracellular calcium dynamics in hepatocyte cell by incorporating the processes like diffusion, advection, buffering etc. The reaction advection diffusion equation has been employed for a two dimensional unsteady state case, to form an initial and boundary value problem. The initial and boundary conditions are formulated based on the physical conditions of cell. Finite volume method and Crank Nicolson scheme have been employed along spatial and temporal dimension respectively to obtain numerical solution. The impact of endogenous and exogenous buffers, advection and diffusion on calcium dynamics in hepatocyte cell has been studied with the help of numerical results. The rise and fall in spatio-temporal calcium concentration in hepatocyte cell in response to specific conditions of advection, diffusion and buffer concentrations is observed. These variations in spatio-temporal calcium concentrations are regulated in narrow range due to fine coordination among these processes of cell under normal environmental and physiological conditions. The proposed model gives better understanding of interrelationship and interdependence of these physical processes for fine coordination among them to maintain structure and functions of cell.

Wonder Woman’s Costume as a Site for Feminist Debate
Authors: Marcus Jaclyn
Published: December 2018

In this article, I examine how much of the fierce debate and discourse around Wonder Woman has centred around her costume. While several academics have addressed the relationship between Wonder Woman and feminism, my article engages with these works to examine the arguments surrounding Wonder Woman’s dress, particularly in the context of comic books and graphic novels that feature the character. The article argues that it is Wonder Woman’s apparel, and not her status as a superhero, that is the site of the controversy surrounding her persona and role as a feminist figure.
Procession of Horsemen on a Gold Plaque from the Siberian Collection of Peter I
Authors: Ochir-Goryaeva M. V.
Published: December 2018

This article describes a group of horsemen depicted on a plaque decorating a rectangular gold casing from the Siberian collection of Peter I. Based on a drawing of the item, published in 1890, the number of characters, their postures and state are assessed. Four horsemen are evidently alive and three are dead. The absence of stirrups indicates the Scytho-Sarmatian age. Judging by the evidence relating to the transportation of the dead among the Turco-Mongol peoples, the scene may be that of a funerary procession. In certain early nomadic burials, the “straddling” position of the deceased (supine with flexed and widely spread legs) is suggestive of dancing or riding. According to a convincing hypothesis proposed by O.V. Obelchenko, who reported such cases in the kurgans of Sogd dating to the 2nd to 1st century BC, the straddling posture of the deceased likely suggests that they had been transported to the grave in the saddle. The funerary procession shown on the gold casing supports such an interpretation. The scene, however, is hardly mundane. More likely, the characters are those of the Scytho-Sarmatian mythology or folklore.
Reconstruction of Wooden and Earthen Buildings in 17th to 18th-Century Russian Forts in Siberia: The Case of the Sayansky Ostrog
Authors: Mainicheva A. Y. , Skobelev S. G. , Berezhenko D. Y.
Published: December 2018

On the basis of the materials of the Sayansky Ostrog (fort), built in the Northern Sayan in 1718, we reconstruct the type of building that was common during the initial stage of the Russian colonization (1600s and 1700s). This is one of the few well preserved Russian forts. While its buildings, their function, and location are known from written sources and from the findings of a complete archaeological excavation, their construction has been hitherto unknown. To reconstruct their size and appearance, we collated archaeological and ethnographic findings, museum materials, and written evidence about the layout of buildings and construction techniques. Judging from the totality of data, we suggest the reconstructions of buildings, such as powder magazine, supply depot, barn with cellar, forge, and commandant’s house. We describe traditions and innovations in construction techniques, choice of building materials, details and blocks, layout of floors, ceilings, and roofs. The commandant’s house reproduces the architectural standards of that time, set by Domenico Trezzini, who designed buildings in the capital and in provincial Russian towns.
The Eastern Slavic Population of Central Asia After the Collapse of the USSR: Ethno-Demographic Processes
Authors: Shustov A. V.
Published: December 2018

By the end of the Soviet period, Eastern Slavs (Russians, Ukrainians, and Belarusians) made up over one fifth of the population of Central Asia. In the USSR, Eastern Slavs were the leading ethnic group, playing the key role in the multinational state. After the collapse of the Soviet Union, the Eastern Slavs, in essence, became an ethnic minority. The new ethno-political situation had a negative impact on their natural increase, which dropped below simple reproduction level, whereas emigration from Central Asia showed an abrupt rise. As a result, the absolute number of Eastern Slavs decreased twofold, and their relative number nearly threefold. Before the collapse of the USSR, their share in this region was 1/4 to 1/5; by the mid-2010s it dropped to 1/12 to 1/13. In Kazakhstan, the decrease was much slower than in other Central Asian republics, so Kazakhstan has become the place where three quarters of Central Asian Eastern Slavs concentrate. This republic therefore has a good chance to remain the most “Slavic” in the region, whereas in other republics of Central Asia the future preservation of the Slavic population is problematic.
An Unusual Burial of a Xiongnu-Sarmatian Era Warrior in the Western Siberian Forest-Steppe: Results of a Paleogenetic Analysis
Authors: Pilipenko A. S. , Cherdantsev S. V. , Trapezov R. O. , Chikisheva T. A. , Pozdnyakov D. V. , Molodin V. I.
Published: December 2018

This article presents the results of a paleogenetic study of skeletal remains of a male from burial 688 at Sopka-2, in the Baraba forest-steppe. The artifacts, the burial rite, and the man’s Central Asian Mongoloid physical type unambiguously indicate a foreigner. We analyzed the uniparental markers, such as mitochondrial DNA (HVRI sequence and informative positions in the coding part of mtDNA) and Y-chromosome (allelic profile of 17 STR-loci). The male’s mtDNA belongs to the East Eurasian haplogroup D4b1, and his Y-chromosome haplogroup Q (Q1a) is likewise East Eurasian. Thus, the individual’s eastern origin has been established, consistent with his physical type. The phylogeographic analysis, using data on ancient and modern populations of Eurasia, revealed the presence of the East Eurasian D4b1-haplogroup both in the eastern and western Eurasian steppes. Importantly, it was present in Scythians of the northern Pontic area. Genetic data, then, do not allow to locate the region whence the individual had migrated to Baraba. We propose a scenario that explains the disagreement between the paleogenetic and the craniometrical evidence, indicating eastern origin, on the one hand, and the predominantly western (Sarmato-Alanian) parallels to the funerary items, on the other. We discuss the possibilities and limitations of the paleogenetic approach to reconstructing the origins of ancient individuals.
Armed Violence Among the Altai Mountains Pastoralists of the Xiongnu-Sarmatian Age
Authors: Tur S. S. , Matrenin S. S. , Soenov V. I.
Published: December 2018

On the basis of perimortem cranial injuries, we examine armed violence among the Altai Montains nomadic pastoralists during the Xiongnu-Sarmatian period (2nd century BC to 5th century AD), when this region was within the military and political orbit of the Central Asian nomadic empires—Xiongnu, Xianbei, and Zhouzhan. The sample included 470 crania from 20 cemeteries of the Bulan-Koba Culture. Blade wounds, depressed fractures, and penetrating projectile wounds were registered. Additionally, weapon related lesions of the postcranial skeleton (arrowheads stuck in the bones and blade wounds), as well as possible cases of scalping, decapitation, and severed limbs were recorded. The frequency of perimortem cranial traumas is 13.3% in males, 6.4% in females, and 4.8% in subadults. This rate shows considerable variation across local groups. During the Xiongnu-Xianbei period (2nd century BC to early 3rd century), perimortem trauma was mainly related to interpersonal and local intergroup violence. Between the late 3rd century AD and the 5th century AD, following the disintegration of the Xianbei Empire and the rise of intergroup clashes, the Bulan-Koba people became also involved in military clashes with foreign tribes.
“Abandoned, Tied, Flexed”: An Anthropological Study of an Unusual Late Sarmatian Burial in the Southeastern Urals
Authors: Fedorov V. K. , Nechvaloda A. I. , Rafikova Y. V.
Published: December 2018

We describe an unusual triple burial in southern Bashkiria, dating to 100–400 AD. Its peculiarity is that the two males had been buried on the step of the entrance pit in unusual postures—prone with their knees pulled to the chins. A woman buried in the undercut lay in a normal (supine) posture. The prone position of the dead is quite rare at Late Sarmatian cemeteries, and flexed burials are exceptional. The anthropological examination revealed that the physical types of the buried persons were different: while all of them were narrow-faced Caucasoids, the features of one male, unlike those of other persons, indicate Mongoloid admixture. All the individuals are similar to those buried at Pokrovka-10, a Late Sarmatian cemetery in the Orenburg Region. Graphical reconstructions of the appearance of one male and the woman were made. The postcranial skeletons of all individuals reveal multiple pathologies. To explain the unusual burial rite, we discuss various possibilities, such as that the bodies of the males had been tied up to counter the evil that they might inflict; that they had been sacrificed; or that they all had died of a fulminant infectious disease. The uniqueness of the burial prevents us from selecting one of these options. The humble status of the males may illustrate the words of Ammianus Marcellinus about the maltreatment of the elderly among the Alans.
Psychological counseling for muslims: the analysis of foreign literature
Authors: Pavlova O.S.
Published: December 2018

The article presents a survey of foreign literature on various aspects of the theory and practice of psychological counseling for Muslims. Psychological counseling for Muslims is a professional psychological aid which uses knowledge about the peculiarities of the client’s faith that are important for him as an individual: his religious views, religious language, sacred stories and legends, sacral practices, as well as the traditions and customs of Muslim peoples. The possibilities of using such spiritual practices as Islamic meditation and Islamic reasoning in psychological work with Muslims are shown. Also the article provides an analysis of the main problems arising during the family therapy of Muslims and describes the professional qualities of a psychologist that are necessary for effective work with clients who profess Islam. In conclusion, it is shown that the solution of psychological problems of believers is difficult or impossible to achieve without a trust that is formed between a client and a psychologist and based on their mutual understanding of religious matters.
Toy as a conditional object
Authors: Ryabkova I.A. , Sheina E.G.
Published: December 2018

The paper presents the review of literature devoted to research of toys. The authors’ focus is on the main function or special characteristics of a toy, that make it a toy. A toy is understood as a specifically playing object which means that it possesses the main characteristic of a play – the discrepancy between real and semantic field, i.e. it possesses conditionality. Conditionality of a play object provokes a person to attribute some meanings to the object i.e. it stimulates him to create imaginary situations. Imagination or creation of an imaginary situation is connected with the inner world, with the personal experience of a player, which a toy can only discover, but not produce. This paper presents research data that show that a toy does not develop a child by itself. For example, it cannot be a source of aggressive behavior or early sexualization, just like it cannot teach kindness and mutual assistance.
Empathic Behavior in Early Childhood under Condition of Taking the Mom’s Role in the Play
Authors: Yudina T.O.
Published: December 2018

Following the modern theoretical and empirical data on the problem of relation between the role-taking and empathy abilities we supposed that empathic behavior in early childhood could be realized through acquiring the role “mom” within the role playing. In order to test our suppose we have conducted the ingroup experiment with 36 toddlers (M=35 months) and compared the frequency of the empathic behavior under two conditions: 1) taking the role of mom and 2) taking the role of friend by the toddler withing the experimental story-play with toys. According to our hypothesis we expected that children would display the empathic behavior more frequent in the condition of taking the mom’s role. Our hypothesis was not confirmed since the difference between conditions has been not significant. Such results reveal that the parental models do not serve significant mediating role in the child’s learning of prosocial behavior.

Disruptive technologies transforming urban mobility? The role of the ecobee urban maglev system in the seoul traffic vision 2030, South Korea
Authors: Hekler Martina , Klühspies Johannes
Published: December 2018

The dynamics and extent of disruptive technologies have been very well developed in Asian cities by the beginning of the 21st century, and are becoming particularly future-oriented. It also appears that urban mobility strategies in Asia are hardly slowed by resistance such as seen in the European context, where holding on to existing systems is the norm. The effects of accelerated mobility strategies in Asia are already apparent compared to what may be expected in Europe. So one could ask, which innovation processes will allow mobility to further develop? How will urban transport systems likely change in the future to minimize adverse impacts of current forms of mobility? In looking forward, any implementation of innovative mobility strategies heavily depends on spatial structures, transport networks and technologies as well as a political planning and decision-making. In Asia, concepts of transport and innovative transportation concepts (such as Rotem’s Ecobee Urban Maglev) are developing with considerable promise, which, if successful, can turn into trendsetters with considerable future relevance on a global scale.

Then the corresponding unified modeling language models, use case diagram, state diagram, activity diagram and sequence diagram, are developed. The state diagram of operation process is using to describe the state transition during the period from initial state of the OTS to the completion of the operation. The activity diagram of train operation process focuses on the control relationship during the period from one activity to another, which can describe the interaction exactly between OTS, DCS and VCS. The sequence diagram, behavior of use case, focuses on the sequence of information sent by objectives, in which a group of objectives and information transfer are presented. And according to these models, the test cases of the specified case are generated.
Results: The generated test cases are all executed in the developed lab-test system. The results show that the generated test cases can fully simulate the common situations of the operation scene, and effectively improve the test efficiency and test quality. We designed the experiments as followings: 85 test cases for terminal system design of operator, 68 test cases for train automatic operation design, 31 test cases for central diagnostic system design. All of the designed test cases are examined through the test platform, covering all main scenes in operation process. The errors or detects found in tests are solved by finding the reasons and modifying the code, etc. Finally, the pass rate of the method proposed in this paper is 100 %. 
Conclusion: The UML based method of test case generation implements the generation process and achieves the test cases and verification for CCS. Through the test practice, test cases designed can fully simulate all kinds of common situations in the operation site. What’s more, the test cases also realize early detection of errors and defects in the system and repair them. It is useful to improve the efficiency on-site testing process, to reduce the cost of time and test quality. The method can provide theoretical basis and reference for further testing of high speed maglev CCS.

Results of an International Survey among Transport Experts and Specialists Maglev.
With the aim of tracking current trends in the market perspectives of magnetic levitation, or maglev technologies, the non-profit International Maglev Board conducted a primary study in the spring of 2018 among maglev specialists and transportation professionals. More than 1 000 professionals took part in the survey. Main topics of the study are questions comparing the suitability of conventional wheel-on-rail and maglev technologies according to application areas. Predicted opportunities and developments in maglev technology, acceptance issues and research needs are analyzed. The results are broken down by expertise and nationality of the participants. This short version presents selected findings of the survey in compressed form.
Background: There is an obvious need for information on international trends in the application of Maglev transport technologies. The study attempts to grasp the global dimension of magnetic levitation developments in a structured way.
Aim: To track current trends in magnetic levitation transport system innovation. Identify perspectives, research tasks and implementation barriers. Comparison of magnetic levitation systems with steel wheel systems. Analysis of the key topics of the debate.
Methods: Primary study in spring 2018 among 1 058 maglev specialists and transport experts. Internet-based online survey.
Results: The ratings vary greatly according to the expertise and origin of the respondents. In certain fields of application, wheel-rail systems remain the preferred transport technology. But in certain other fields of application, maglev technologies have become preferred over conventional steel-wheel-rail by a majority of transport professionals. This is particularly the case for high-speed maglev transport and for the new application of maglev elevators in buildings. At the same time, many respondents see a continuing need for research.
Conclusion: Overall, there is a differentiated picture. Respondents from North and South America, Russia and Asia are on average particularly open to an implementation of certain maglev technologies.
Garcilaso de la Vega y Guaman Poma de Ayala en El pez de oro de Gamaliel Churata: noticia de una polémica
Authors: Marsal Meritxell Hernando
Published: December 2018

Resumen: La obra del escritor peruano Gamaliel Churata es adoptada por la crítica literaria postcolonial latinoamericana como un modelo productivo, que anticipa y pone en práctica sus observaciones. Su trabajo se nutre de textos anteriores, especialmente de los cronistas de la época colonial, Garcilaso de la Vega y Guaman Poma de Ayala. En ellos, el gesto de resistencia a la imposición colonial está tempranamente registrado y Churata lo rescata y activa en su obra. De esta manera, lo colonial, en el límite de lo dicho, y lo postcolonial, se encuentran en una relación activa. Ahora bien, estos dos cronistas constituyen una dicotomía conflictiva en la primera parte de El pez de oro, que identifica uno con la conformidad al sistema y el otro con su subversión. En el presente trabajo serán analizados los términos de esta polémica para resaltar cómo Churata se enfrenta a la crítica literaria hispanizante y a sus lecturas, desautorizando la preeminencia de Garcilaso, pero evita al mismo tiempo simplificaciones, y valora y asume a los dos cronistas como modelos de un proyecto de descolonización cultural, en que lo indígena deviene un paradigma de conocimiento y de vida.Palabras clave: crítica postcolonial; Gamaliel Churata; Inca Garcilaso de la Vega; Guaman Poma de Ayala.Abstract: The Peruvian writer Gamaliel Churata is adopted by Latin American postcolonial literary criticism as a productive model, which anticipates and puts into practice its thoughts. His work is nourished by previous texts, especially the chroniclers of the Colonial Era, Garcilaso de la Vega and Guaman Poma de Ayala. From them, Churata rescues and activates the gesture of resistance to the colonial imposition. This way, the colonial, in the limit of what could be said, and the postcolonial, are in an active relationship. However, in the first part of El Pez de Oro Churata establishes a conflicting dichotomy between these two chroniclers, which identifies one of them with conformity to the system and the other with its subversion. In the present essay, the terms of this controversy will be analyzed to highlight how Churata confronts Hispanic literary criticism and its readings, disavows Garcilaso’s pre-eminence, but at the same time avoids simplification, and assumes the two chroniclers as models of a project of cultural decolonization, in which the indigenous becomes a paradigm of knowledge and life.Keywords: postcolonial criticism; Gamaliel Churata; Inca Garcilaso de la Vega; Guaman Poma de Ayala.

Authors: Rodrigues Adriana Cristina Aguiar
Published: December 2018

Resumo: O artigo analisa o compromisso com a memória tutsi e o teor testemunhal presente na narrativa da escritora e sobrevivente ruandesa Scholastique Mukasonga. Na primeira seção, analisa-se o contexto de surgimento de uma literatura decorrente do genocídio, dando destaque ao trabalho (quase etnográfico) de inscrição da cultura tutsi e da memória das vítimas e sobreviventes empreendido por Mukasonga. Em seguida, passa-se a analisar como a autora constrói em sua narrativa o relato de teor testemunhal, ao mesmo tempo em que revisa, via literatura, os rumores e os discursos – nascidos no período colonial e mantidos durante a independência do país – que culminaram na catástrofe de 1994.Palavras-chave: memória; rumor; teor testemunhal; Scholastique Mukasonga.Abstract: This article analyzes the commitment to Tutsi memory and the testimonial content, which exists within the narrative of Rwandan writer and survivor Scholastique Mukasonga. In the first section, the context of a literature arising from the genocide is analyzed, highlighting the work (almost ethnographic) of the inscription of the Tutsi culture and the memory of the victims and survivors done by Mukasonga. Then it proceeds to analyze how the author constructs in her narrative the report of testimonial content, at the same time that it reviews, through literature, the rumors and discourses – generated in the colonial period and maintained during the independence of the country – that culminated in the 1994 catastrophe.Keywords: memory; rumor; witness content; Scholastique Mukasonga.
Être ou ne pas être post(-)coloniale : le cas de la littérature des intrangers
Authors: Marcu Ioana
Published: December 2018

Résumé : Dans l’espace francophone, parler de « littératures postcoloniales » représente un véritable défi. D’une part, il s’agit d’un courant littéraire envisagé avec méfiance, voire même réticence et hostilité, malgré les écrivains et les philosophes français et francophones cités comme précurseurs. De l’autre part, les caractéristiques éclectiques du corpus postcolonial donnent lieu à un rassemblement sous un même label d’œuvres littéraires protéiformes (aussi bien sur le plan de l’espace et de l’époque d’émergence que sur le plan des problématiques traitées et de la langue d’écriture) ; parallèlement, elles entraînent une mise à l’écart d’un ensemble littéraire hybride (à cause de l’histoire personnelle des écrivains et de leur langue d’expression). Dans notre contribution, nous nous proposons de voir si la littérature des intrangers, produite par les descendants d’immigrés maghrébins ou de harkis, présente vraiment les caractéristiques du corpus post(-)colonial. Nous fonderons notre analyse sur deux romans de l’extrême contemporain appartenant à deux écrivaines ayant connu un destin complètement différent : Un homme, ça ne pleure pas (2014) de Faïza Guène, chouchou des médias, cadette d’une famille originaire d’Algérie, née à Bobigny et ayant grandi dans la cité des Courtillières à Pantin, et Mohand le harki (2003) de Hadjila Kemoum, elle-même fille de harki.Mots-clés : post(-)colonial, intrangers, hybride, harkis, immigration.Abstract : In the French-speaking space, talking about “postcoloniales literatures” represents a real challenge. It is about a literary movement envisaged suspiciously, even reluctant and hostile, despite the French and Francophone writers and philosophers cited as being the precursors. On the other hand, the eclectic peculiarities of the postcolonial corpus give rise, at the same time, to a gathering under the same label of protean literary works, from the point of view of the space and of the period of emergence as well as the point of view of the problems treated and of the language of writing. Meanwhile, it also considers the hybrid corpus because of the personal history of the writers and of their language of expression. In our contribution, we investigate whether the literature of intrangers, produced by the descendants of Maghrebi immigrants or harkis, really presents the characteristics of the post(-)colonial corpus. We base our analysis on two novels of two contemporary female writers who knew a completely different destiny: Un home, ça ne pleure pas (2014), of Faïza Guène, younger child of an Algerian family, born in Bobigny and raised in Courtillières, and Mohand le harki (2003), of Hadjila Kemoum, herself girl of harki.Keywords : post (-) colonial, intrangers, hybrid, harkis, immigration.
Feições do racismo no conto “Pixaim”, de Cristiane Sobral
Authors: Silva Franciane Conceição da
Published: December 2018

O presente artigo analisa o conto “Pixaim”, extraído da coletânea Espelhos, miradouros, dialéticas da percepção (2011), da escritora Cristiane Sobral. No conto encena-se a relação conflituosa entre a protagonista negra e a sua mãe branca. Nesta relação, o ato da mãe de submeter o cabelo da filha a diversos processos de alisamento, tentando amansar a rebeldia dos fios crespos, metaforiza a dificuldade da mulher branca em aceitar o fenótipo da criança negra. No decorrer da análise do conto, procuramos compreender as estratégias narrativas utilizadas pela autora para encenar a violência do racismo que se manifesta no contexto de uma família interracial. Aprofundamos a análise da temática abordada na narrativa de Sobral, recorrendo a estudos de diferentes áreas do saber, destacando-se a Psicologia e a Psicanálise.
Espectros de Baldwin
Authors: Coswosk Jânderson Albino , Salgueiro Maria Aparecida Andrade
Published: December 2018

O artigo explora a potência crítica e narrativa do documentário I Am Not Your Negro (2016), do diretor haitiano Raoul Peck (1953-), resultante de uma pesquisa intensa do diretor nos arquivos pessoais do escritor e ensaísta afro-americano James Baldwin (1924-1987). Apontaremos de que modo Baldwin, através da manipulação imagética e textual proposta por Peck, ressuscita questões graves da história das tensões raciais nos Estados Unidos, que dividiram o país antes e após o início dos anos 1970, ou ainda, após a luta pelos direitos civis e a morte de seus três grandes amigos: Martin Luther King Jr., Medgar Evers e Malcolm X. Evidenciaremos como o documentário expõe um pano de fundo do passado que se confunde com imagens, narrativas, corpos e nomes do presente, ao destacar a importância das reflexões de Baldwin para a luta contra o racismo e a violência ainda impostos à população negra estadunidense na contemporaneidade.
Representando a resistência negra no Brasil: originalidade e limites de Um defeito de cor, de Ana Maria Gonçalves
Authors: Delgado Gabriel Estides
Published: December 2018

Com uma poética calcada no transplante cultural africano, Ana Maria Gonçalves leva a cabo, em Um defeito de cor, a tarefa titânica de recontagem da resistência negra no país a partir de um ponto de vista feminino e negro. No relato de uma narradora octogenária, ex-escrava de nação jeje, o fôlego monumental do romance perfaz aprofundada vivência de culturas originárias, incorporando léxicos de etnias traficadas e ritualísticas totêmicas, em tentativa de representação da importância de tal legado para a integração negra no Brasil. Sustentamos que a originalidade daí desprendida é capaz de contraditar um dos marcos da sociologia crítica brasileira: a tese A integração do negro na sociedade de classes, de Florestan Fernandes. Essa complementação fundamental a historiografias consagradas sobre as populações afro-brasileiras depende das possibilidades do registro ficcional, as quais, no entanto, ficam obstadas por escolhas formais conservadoras, que limitam, sem anular, a potência literária da obra.
