Published: August 2019

Background

The peroxiredoxins (PRDXs) gene family has been demonstrated to participate in carcinogenesis and development of numerous cancers and the prognostic values in several cancers have been evaluated already. Purpose of our research is to explore the expression profiles and prognostic values of PRDXs in breast cancer (BrCa).

Methods

The transcriptional levels of PDRX family members in primary BrCa tissues and their association with intrinsic subclasses were analyzed using UALCAN database. Then, the genetic alterations of PDRXs were examined by cBioPortal database. Moreover, the prognostic values of PRDXs in BrCa patients were investigated via the Kaplan-Meier plotter.

Results

The transcriptional levels of most PRDXs family members in BrCa tissues were significantly elevated compared with normal breast tissues. Meanwhile, dysregulated PRDXs expression was associated with intrinsic subclasses of BrCa. Besides, copy number alterations (CNA) of PRDXs positively regulated their mRNA expressions. Furthermore, high mRNA expression of PRDX4/6 was significantly associated with poor overall survival (OS) in BrCa patients, while high mRNA expression of PRDX3 was notably related to favorable OS. Simultaneously, high mRNA expression of PRDX1/2/4/5/6 was significantly associated with shorter relapse-free survival (RFS) in BrCa patients, while high mRNA expression of PRDX3 was notably related to favorable RFS. In addition, the prognostic value of PRDXs in the different clinicopathological features based on intrinsic subclasses and chemotherapeutic treatment of BrCa patients was further assessed in the KM plotter database.

Conclusion

Our findings systematically elucidate the expression profiles and distinct prognostic values of PRDXs in BrCa, which might provide novel therapeutic targets and potential prognostic biomarkers for BrCa patients.

Published: August 2019

Postsurgical trigeminal neuralgia (TN), although rare, can lead to significant hemodynamic perturbations by triggering the trigeminocardiac reflex (TCR). The combination can lead to diagnostic as well as management challenges for clinicians. We present the case of a patient with a parotid abscess, which developed as a complication of his otolaryngologic surgery, and which led to repeated episodes of symptomatic bradycardia associated with cardiovascular collapse. This case highlights the importance of heightened awareness, early diagnosis, and timely treatment of postsurgical neuropathic pain syndromes to avoid life-threatening complications.

Published: August 2019

Purpose

Previous studies report memory and functional connectivity of memory systems improve acutely after a single aerobic exercise session or with training, suggesting that the acute effects of aerobic exercise may reflect initial changes that adapt over time. In this trial, for the first time, we test the proof-of-concept of whether the acute and training effects of aerobic exercise on working memory and brain network connectivity are related in the same participants.

Methods

Cognitively normal older participants (N = 34) were enrolled in a randomized clinical trial (NCT02453178). Participants completed fMRI resting state and a face working memory N-back task acutely after light- and moderate-intensity exercises and after a 12-wk aerobic training intervention.

Results

Functional connectivity did not change more after moderate-intensity training compared with light-intensity training. However, both training groups showed similar changes in cardiorespiratory fitness (CRF) (maximal exercise oxygen uptake, V˙O2peak), limiting group-level comparisons. Acute effects of moderate-intensity aerobic exercise on connections primarily in the default network predicted training enhancements in the same connections. Working memory also improved acutely, especially after moderate-intensity, and greater acute improvements predicted greater working memory improvement with training. Exercise effects on functional connectivity of right lateralized frontoparietal connections were related to both acute and training gains in working memory.

Conclusions

Our data support the concept of acute aerobic exercise effects on functional brain systems and performance as an activity-evoked biomarker for exercise training benefits in the same outcomes. These findings may lead to new insights and methods for improving memory outcomes with aerobic exercise training.

Authors: Wang Wenxia , Zheng Xiaoyong , Sun Zuoyong
Published: August 2019

Objective: To compare and analyze the clinical effects of internal fixation of minimally invasive elastic stable intramedullary nail and plate in the treatment of pediatric femoral shaft fracture.

Methods: A total of 120 children with femoral shaft fractures who were admitted to our hospital from December 2016 to April 2018 were enrolled. The children were divided into an observation group and a control group by random number table, with 60 children in each group. The children in the observation group underwent internal fixation of minimally invasive elastic stable intramedullary nail, while those in the control group underwent open reduction based on internal fixation of plate. The surgical status and postoperative complications of the two groups were observed and compared, and Kolmert knee function scoring criteria were used for assessing the surgical effects of children.

Results: The operation duration, intraoperative blood loss, hospitalization duration, fracture healing time and time of off-bed loaded activity of the observation group were significantly shorter than those of the control group, and the differences were statistically significant (P<0.05). The excellent and good rate of fracture healing in the observation group was 100%, which was higher than that of the control group, 83.33%, and the difference was statistically significant (P<0.05). The total incidence rate of complications in the observation group was 8.33%, which was lower than that of the control group, 10.00%, but the difference was not statistically significant (P>0.05).

Conclusion: Pediatric femoral shaft fractures can be treated with internal fixation of minimally invasive elastic intramedullary nail, and it has advantages of significant curative effect, small trauma and fast postoperative recovery, which is conducive to fracture healing and worth promoting.

Published: August 2019

Objective: To present the etiological factors of patients with Retinal Vein Occlusion (RVO) under the age of 50 years.

Methods: The study was conducted at Ege University Medicine Faculty Department of Ophthalmology. The clinical records of patients with RVO under the age of 50 seen between January 2014 and March 2018 were analyzed retrospectively. Forty patients comprised the study. Detailed ophthalmologic examination was performed. Past medical history, drug use, thrombophilic features, hyperviscosity syndromes and pathologies that may cause vasculitis were noted.

Results: Forty patients, 22 (55%) male and 18 (45%) female, were included. Mean age was 41.6 ± 10.01 years. Mean intraocular pressure and best-corrected visual acuity were 16.8 ± 5.47mmHg and 0.76 ± 0.64 logMAR, respectively. Hyperhomocystenemia (15 patients, 37.5%), Behçet’s disease (three patients, 7.5%), diabetes and/or hypertension (16 patients, 40%), methylenetetrahydrofolate reductase gene mutation (11 patients, 27.5%), prothrombin gene mutation (four patients, 10%) and factor V Leiden mutation (five patients, 12.5%) were present among the patients as etiological factor. Multiple etiological factors were detected in 11 (27.5%) patients. Factor V Leiden mutation and methylenetetrahydrofolate reductase gene mutation were detected in one patient (2.5%) with Behçet’s disease. Four patients with diabetes and/or hypertension also had hyperhomocystenemia and one of them had additionally prothrombin gene mutation. Two patients with methylenetetrahydrofolate reductase gene mutation also had a factor V Leiden mutation and one of them had additionally a prothrombin gene mutation. Three patients with methylenetetrahydrofolate reductase gene mutation also had hyperhomocystenemia and one patient with prothrombin gene mutation also had methylenetetrahydrofolate reductase gene mutation.

Conclusions: Etiological factors that might result in RVO in young individuals should be investigated in detail. Targeted therapies may help to prevent development of new RVOs and potential vascular problems in other organs.

A New Index of Housing Sentiment
Authors: Bork Lasse , Møller Stig V. , Pedersen Thomas Q.
Published: August 2019

We propose a new measure for housing sentiment and show that it accurately tracks expectations of future house price growth rates. We construct the housing sentiment index using partial least squares on household survey responses to questions about buying conditions for houses. We find that housing sentiment explains a large share of the time variation in house prices during both boom and bust cycles, and it strongly outperforms several macroeconomic variables typically used to forecast house prices.

Conflitos no Mar do Sul da China: o que o Brasil tem a ver com isso?
Authors: Simões de Moraes Lima Leticia Cordeiro
Published: August 2019

As disputas territoriais no Mar do Sul da China (MSC) vêm despertando a atenção ao redor do globo. Contudo, tais questões passaram a receber maior atenção devido à elevação das tensões entre China e EUA naquela região. No Brasil, há pouco destaque e pouca informação sobre os principais atores envolvidos e quais as consequências do início de um conflito entre duas grandes potências na Ásia-Pacífico. Apesar de estar no imaginário do brasileiro de que se trata do ‘outro lado do mundo’ e que o impacto de um possível embate naquelas águas seria muito pequeno para o país, não poderíamos estar mais equivocados. Por que o Brasil deve se preocupar, mas também se informar sobre um conflito no MSC? Este artigo pretende apresentar em linhas gerais um panorama dos lados do conflito e as razões para o Brasil ser um dos primeiros afetados por uma hipotética crise lá.

Team members will have different perspectives, values, beliefs and goals and, in certain circumstances, these differences may escalate into conflict. While conflict cannot be avoided, it can be minimised and resolved. This article will discuss the strategies required by head nurses/nurse leaders in order to effectively manage conflict within a team.
Poisons affecting the liver
Authors: Bates Nicola
Published: August 2019

The liver is a multifunction organ involved in metabolism and synthesis of essential compounds. As the first organ after the gut to receive ingested substances and because of its role in metabolism, it is at particular risk of damage from ingested poisons and their toxic metabolites. Poisons affecting the liver are discussed in this second article on poisons by organ system. Among the most readily accessible liver toxicants are xylitol and paracetamol, which are commonly available in the home. The mechanism of xylitol-induced liver toxicity is unknown, but paracetamol is metabolised to toxic metabolites when normal mechanisms are overwhelmed and/or inadequate. Various natural sources of hepatotoxins are also discussed including some mushroom species (e.g. some Amanita species and Gyromitra esculenta), some cyanobacteria (blue-green algae) and plants such as cycads which can be grown as houseplants. The mechanism of liver damage with these natural sources includes direct hepatotoxins and toxic metabolites. The management of toxic liver damage is generally supportive with gut decontamination where appropriate and liver protectants, such as acetylcysteine and S-adenosyl-L-methionine (SAMe).

Captured by the Quagmire: Iraq's Lost Generation and the Prospects for Children across the Arab Region Today
Authors: Ismael Shireen T.
Published: August 2019

Increasing legibility is now available through NGO and U.N. data, which has been collected across Iraq, for an assessment of the contemporary state of social welfare amongst Iraqi children and the residual effects of the regime change that took place in 2003. This data will be examined, contextualized to the post-2003 period and the potential for theory-building will be explored. The picture that emerges suggests the level of humanitarian catastrophe resulting from the U.S.-led 2003 invasion and occupation recommends further interrogation of the policy of ‘regime change’ for its role in informing U.S. actions. Additionally, such catastrophic humanitarian outcomes lead to questions surrounding future use of regime change efforts. The Iraqi case exhibits the destruction of the state apparatus, with social and cultural institutions built from Iraq's 1932 independence, rather than a direct replacement of those ruling the state. Iraqi children, not yet born when the 2003 invasion took place, have borne the brunt of the Iraqi state's destruction, with an absence of care from those who carried out the change in regime.

No passado recente, a família constituía-se como modelo motivacional para o potencial empreendedor dos seus descendentes. No período de pós-crise económica europeia, desconhece-se o seu papel. Este artigo visa analisar em que medida a presença de empresários na família influencia o potencial e as motivações empreendedoras dos seus descendentes.Uma amostra de 966 estudantes do Ensino Superior português respondeu ao inquérito Motivações Empreendedoras, que evidenciou adequadas propriedades psicométricas.Verificou-se uma influência positiva da presença de empresários na família nas motivações de realização familiar e societal, apesar de uma ausência de efeito nas motivações de recursos e rendimentos, bem como de prestígio e de aprendizagem/desenvolvimento pessoal.Ter empresários na família influenciou positivamente os fatores Judging Perceiving e Thinking Feeling do Carland Entrepreneurship Index. Contudo, a path analysis revelou a inexistência de um efeito direto da presença de empresários na família no potencial empreendedor e nas motivações de realização familiar e societal dos estudantes, apesar de se ter registado um efeito indireto significativo, tendo por mediadores o desejo dos estudantes em trabalhar por conta própria e a capacidade de criar uma empresa. Ter empresários na família evidenciou ainda um efeito direto nestes mediadores, bem como em ter/implementar ideias de negócio.
Transformational leadership and innovation adoption: Is there a moderation role of personal initiative and job control?
Authors: Zappalà Salvatore , Toscano Ferdinando
Published: August 2019

Hospital managers and chief physicians, but also doctors and nurses, in an effort to face  constant changes, are involved in innovation. This study examines if transformational leadership style is related to adoption of employees’ suggestions, and if personal initiative and job control moderate this relationship. Nurses, doctors, and auxiliary and technical collaborators (n = 137), of an Italian public hospital, participated in this study. Results show that transformational leadership was correlated to innovation adoption but, when examined moderators were included in the analysis, the relation was no more significant. Personal initiative and job control did not moderate the relationship between transformational leadership and innovation adoption but they do have a significant direct effect on innovation adoption. Findings suggest that innovation in hospitals is more related to personal variables, like personal initiative and job control, rather than to transformational leadership.

Este artigo tem como principal objetivo debater o conceito de expressão livre nas crianças (6-10 anos) no contexto da aprendizagem da Educação e Expressão Plástica (EEP). Nesta discussão mobiliza-se o papel que é atribuído à expressão comummente afirmada nos discursos dos docentes do 1º Ciclo do Ensino Básico (1º CEB) de que as crianças são livres por natureza, exprimindo-se plasticamente de acordo com a sua imaginação e a sua criatividade. Esta maneira de pensar, conhecer e dizer tem-se constituído numa quase aceitação coletiva do pensamento educativo na prática da educação e expressão plástica e nas artes em geral, tornando-se num mito pedagógico e numa verdade intuída.É em torno da análise e da problematização dos discursos de um grupo de seis docentes do 1º ciclo do Ensino Básico que se procura clarificar quais os fundamentos que os levam a incentivar e criar condições para o que classificam de expressão livre das crianças.

Transferability and calibration of airborne laser scanning based mixed-effects models to estimate the attributes of sawlog-sized Scots pines
Authors: Korhonen Lauri , Repola Jaakko , Karjalainen Tomi , Packalen Petteri , Maltamo Matti
Published: August 2019

Airborne laser scanning (ALS) data is nowadays often available for forest inventory purposes, but adequate field data for constructing new forest attribute models for each area may be lacking. Thus there is a need to study the transferability of existing ALS-based models among different inventory areas. The objective of our study was to apply ALS-based mixed models to estimate the diameter, height and crown base height of individual sawlog sized Scots pines ( L.) at three different inventory sites in eastern Finland. Different ALS sensors and acquisition parameters were used at each site. Multivariate mixed-effects models were fitted at one site and the models were validated at two independent test sites. Validation was carried out by applying the fixed parts of the mixed models as such, and by calibrating them using 1â3 sample trees per plot. The results showed that the relative RMSEs of the predictions were 1.2â6.5 percent points larger at the test sites compared to the training site. Systematic errors of 2.4â6.2 percent points also emerged at the test sites. However, both the RMSEs and the systematic errors decreased with calibration. The results showed that mixed-effects models of individual tree attributes can be successfully transferred and calibrated to other ALS inventory areas in a level of accuracy that appears suitable for practical applications.Pinus sylvestris

Published: August 2019

Day by day the population of India is rising. So it is important to fulfill the need of food, modernization of agricultural
sectors. Farmers in our country use fertilizers and pesticides on crops for removing weeds and other unwanted
vegetation, insecticides for controlling a wide variety of insects, preventing the spread of bacteria, and compounds
used to control mice and rats. Conventionally the spraying is done by farmers carrying backpack sprayer and
fertilizers are sprayed manually. It is very harmful to their health and can be dangerous. The efforts required are on
the higher side. Pesticide spraying machine is available in the market so there is no issue. But it is acquiring high cost
for buying two separate equipment’s for fertilizer and pesticide spraying which isn’t affordable to farmers. So by
taking into consideration the present problem faced by farmers we are coming up with the solution of “Dual Sprayer
for Pesticides and Fertilizers”. The aim of our project is to minimize the health issues of the farmer, to provide more
feasibility with minimum possible cost, to reduce the efforts of farmers of fertilizer spraying and provide both
fertilizer and pesticide sprayer in one setup.
A Review Paper on Stir Casting of Reinforced Aluminium Metal Matrix
Composite (MMC)
Authors: Singh Gagandeep , Kumar Ashwani
Published: August 2019

This paper deals about the importance of composites as engineering materials which is reflected by the fact that most
of the materials which are available in the market are composites. These composites replaced cast iron and bronze
alloys due to their poor wear and seizure resistance. Due to the wide choice of materials, today's engineers are posed
with a big challenge for the right selection of a material and the right selection of a manufacturing process for an
application. There are more than 50,000 materials available to engineers for the design and manufacturing of
products for various applications. In the present study, based on literature review, the effect of Boron Carbide particle
reinforcements are finding increased applications in aerospace, automobile, space, underwater and transportation
applications. This is mainly due to improved mechanical and tribological properties like strong, stiff abrasion and
impact resistant and it is not easily corroded. In a review of different researchers have been made to consolidate some
of the aspects of mechanical and wear behaviour of Aluminium Metal Matrix Composites reinforced with Boron
Carbide particles.

Published: August 2019

A study was carried out to evaluate the effects of heating treatment on static hardness of beech (Fagus sylvatica L.)
wood of Albanian origin. The heat treatment was conducted at temperatures 180, 200 and 220°C for 2 hours, at
atmospheric pressure. Samples were produced from logs sapwood of origin from central Albania. Before treatment
the oven dried density was calculated. The weight loss after treatment resulted from the lowest to the highest
temperature respectively 3.57, 5.33 and 9.46%. It was noted a small decrease of hardness for temperatures up to
200°C, while for higher temperature the hardness decreased considerably, up to 20%. Decrease of hardness in
tangential section was lower than in radial one. From the perspective of utilisation it seems that Albanian beech
wood treated at temperatures up to 200°C presents a suitable choice for indoor and outdoor stairs, floor tiles and
parquet.
Effects of coffee management intensification in natural forests on woody species
diversity and structure in Yayo district, south western Ethiopia
Authors: Gamachu Fikiru I. , Jegora Tefera
Published: August 2019

This study was conducted to evaluate the difference between woody species diversity, structure and similarity in natural
forests and adjacent coffee farms in Yayo district, southwestern Ethiopia. Vegetation data were collected from both land
use systems using transects walk lines. The Shannon, Simpson’s, similarity and importance values index were analyzed
using SPSS version 20 software. The result revealed 64 woody species belongs to 31 families from both land uses.
Moraceae had the most diverse family having each 5 and 8 species in coffee farms and natural forests respectively. The
species richness was higher in natural forests (54) than coffee farms (38). Coffea arabica (42.85%) and Celtis africana
(21.14%) those frequently occurred had the highest importance value indices in coffee farms and natural forests
respectively. Of total species recorded, 28 (43.75%) are common, 26 (40.63%) and 10 (15.62%) were unique to natural
forests and coffee farms respectively. The highest number of woody plants per hectare were distributed in diameter at
breast height 5-10cm having 1250 ha−1
(64.10%) in natural forests and 471 ha−1
(72.33 %) in coffee farms. The total
basal areas were 364.44 and 669.84 m2
ha−1
in coffee farms and natural forests respectively. The result indicated that
planting coffee in natural forests with intensified management system causes significant differences on the overall
woody species diversity i.e. the structure, composition and regeneration rates of the forest. Therefore, it is
recommended to plant coffees in home garden and open lands with planting multipurpose shade trees rather than
cultivating it in natural forests.

A novel framework for predicting stock trends and making financial trading, decisions based on a combination of Data
and Text Mining techniques. The prediction models of the proposed system extract data in text content of time-stamped
web documents in addition to traditional numerical time series data, which is also available from the Web. The financial
trading system based on model predictions uses three different trading strategies. In this work, our system is simulated
and evaluated on real-world series of news stories and stocks data using Decision Tree Induction Algorithm.
Performance is the predictive accuracy of the induced models and, more importantly, the profitability of each trading
strategy using these predictions.
Personality disorder traits in young adults with subclinical obsessive-compulsive symptoms: Not just traits related to obsessive- compulsive personality
Authors: Raynal Patrick , Melioli Tiffany , Chabrol Henri
Published: August 2019

Research is scarce regarding personality disorder traits of individuals with subclinical obsessive-compulsive symptoms. Cluster analysis based on obsessional, schizotypal, and borderline personality and autism-spectrum features was conducted on the results for 118 students scoring above cutoff on the Obsessive Compulsive Inventory-Revised. This identified four groups: O, L, S, and A. One third of the sample was represented by individuals with obsessional traits (O), while another third was composed of individuals with low traits (L); the last two profiles corresponded to a cluster with autistic traits (A) and a group with schizotypal and borderline features (S), both clusters together comprising the remaining third. Significant differences were observed between groups, both on personality traits and on psychopathological symptoms. The S cluster displayed the highest scores of suicidality, depression, and obsessive-compulsive symptoms. This study identified meaningful profiles of personality disorder traits, distinct from obsessive-compulsive personality, in individuals with subclinical obsessive-compulsive symptoms.

O presente trabalho pretende analisar a importância da obra do dramaturgo paulista Jorge Andrade (1922-1984), A moratória, no panorama do teatro nacional, procurando evidenciar qual a importância da mesma para a construção de nossa identidade, a partir de uma escrita que conjuga aspectos rurais e econômicos, e que traz como principal aspecto o plano social de conversão ideológica que se verifica a partir de 1930, como analisa Antonio Candido, em seu texto Literatura e desenvolvimento. O pano de fundo de A moratória fixa-se em dois planos temporais, 1929 e 1932, e seus personagens estão perdidos nessa conversão temporal e existencial, capaz de pôr em xeque valores sedimentados, em detrimento da crua realidade que arruína a aristocracia paulistana dona dos cafezais no interior do estado. Comparado em parte com a dramaturgia de Anton Tchekhov, sobretudo com O jardim das cerejeiras, A moratória reúne elementos que dão sólidos contornos a um tipo de drama capaz de incorporar com especificidade as fontes rurais raramente trabalhadas em nossa literatura, ligando-se a produção crítica que, a partir de 1950, abandona de vez o ideal do país novo.Palavras-chave: Teatro brasileiro; Jorge Andrade; A moratória; Identidade nacional.
La vida femenina a través de la mirada de los escritores viajeros en Argentina (1909-1914): manifestaciones y transformaciones
Authors: Giaccio Laura
Published: August 2019

En este artículo examinamos cómo se caracterizó la mujer argentina y su vida diaria por la pluma de algunos escritores que viajaron a Argentina desde Europa en el período 1909-1914. El objetivo del análisis es tratar de vislumbrar, a través de los ojos del viajero, la sensibilidad que gobernó sobre el femenino en la sociedad de Buenos Aires, especialmente en relación con su vida intelectual y artística en un momento de transformación de sentimientos como era al comienzo de siglo XX. Para ello, se considera que las representaciones detalladas de mujeres argentinas fueron mediadas por una mirada masculina, inmerso en una determinada concepción de la vida femenina.Palabras claves: viajantes; representaciones; sensibilidad; vida femenina.
SOBRE COMO MERGULHAR E FICAR DE CABEÇA ENXUTA: A REPRESENTAÇÃO DO ESTRANGEIRO EM CONTOS GAUCHESCOS E LENDAS DO SUL
Authors: Arendt Joao Claudio
Published: August 2019

Este artigo objetiva discutir a representação tanto do brasileiro (especialmente o carioca, o paulista e o baiano) quanto do estrangeiro (o açoriano,  o português, o inglês, o alemão e, em especial,  o castelhano e o espanhol) nas obras Contos gauchescos e Lendas do Sul, de João Simões Lopes Neto. A perspectiva assumida pelo autor, Simões Lopes, e seu narrador, Blau Nunes, é de critica a qualquer influência cultural oriunda do centro e do nordeste do país, e de franca oposição ao que provém do exterior,  especialmente da Europa e da América hispânica. Para embasar a análise, recorre-se à historiografia, à crítica literária e a estudos sobre identidade. Palavras-chave: Simões Lopes Neto; representação; identidade; estrangeiros.
E-PÍSTOLAS: AS VIDEOPOESIAS DE MATILDE CAMPILHO E A RELAÇÃO LITERÁRIA ENTRE BRASIL E PORTUGAL
Authors: Kickhöfel Tiago Radatz , Fonseca Claudia Lorena Vouto da
Published: August 2019

Este texto apresenta um percurso de articulações teóricas e críticas possíveis para a leitura de um projeto literário hipermidiático e do seu reflexo em um sistema cultural mais amplo. Trata-se do projeto videopoético da escritora Matilde Campilho e seus desdobramentos na perplexa relação literária entre Brasil e Portugal. Eis que se divide em duas partes, na primeira justifica sua posição crítica e localiza a poeta e sua produção no estudo, bem como verifica motivações históricas motrizes de tais ruídos no diálogo literário luso-brasileiro; a segunda parte é dedicada à análise formal da videopoesia e suas imbricações no corpus poético selecionado, o videopoema Fevereiro.  O objetivo desta análise é, portanto, entender essa problemática cultural e o modo pelo qual a autora a contornou, isto é, a dupla perspectiva de alteridade que cumpre em seu projeto-processo literário hipermídia.Palavras-chave: identidade; hibridação cultural; videopoesia.
TRANSCULTURACIÓN E IDENTIDAD EN EL PENSAMIENTO DE FERNANDO ORTIZ, SU PERTINENCIA ANTE LA VISIÓN HEGEMÓNICA DE PODER
Authors: Bombino Andres Lora
Published: August 2019

Homogeneizar, imponer una cultura como única y mejor, no reconocer las diferencias, es una herramienta de las estructuras verticales de poder, de un control social que se fundamenta en la vieja y acartonada dicotomía opresor-oprimido; en cambio, reconocer las heterogeneidades, las diferencias y alteridades, y por ende que la constitución de la cultura es compleja, potencialmente transcultural y con ello cambiante y transformativa, permite abrir nuevas perspectivas que, asimismo, nos acercan a una ética realista y con ello a la construcción de un mundo más justo con vidas más interesantes y dignas de ser disfrutadas. En nuestro país  la obra de Fernando Ortiz es básica para los estudios de la identidad cubana, y en sentido general, para los estudios referidos a la cultura cubana, plasmados en libros, ensayos, artículos y conferencias  de necesaria referencia para cualquier estudio sobre el tema. Pero su mayor aporte, desde el punto de vista  de concepto, es la introducción del neologismo transculturación, para referirse al intercambio entre distintas culturas y así echar por tierra teorías que había minimizado o,  en el mejor de los casos,  convertido en “culturas menores”, todo el rico legado cultural de Latinoamérica y el Caribe. La globalización neoliberal, la crisis económica actual y los cambios sucedidos en América Latina, así como la perenne lucha contra el capitalismo imperial de los Estados Unidos, hacen de este concepto  en extremo útil para los estudios referidos a la identidad en todo el continente. El presente trabajo aborda la transculturación dentro del proceso identitario cubano, frente a la visón hegemónica de poder. Palabras claves: Transculturación; Fernando Ortiz; proceso identitario cubano.
TESEU, O LABIRINTO E SEU NOME: COMO HOMI K. BHABHA PODERIA NOS AJUDAR A COMPREENDER UMA PASSAGEM DE MOI, TITUBA SORCIÈRE…, DE MARYSE CONDÉ?
Authors: Oliveira Jonata , Alves Alcione
Published: August 2019

Propõe-se uma interpretação da obra de Maryse Condé, intitulada Eu, Tituba, feiticeira...negra de Salem (1997); o romance é inspirado na história de Tituba, sendo esta a única negra entre as mulheres condenadas no trágico incidente, ocorrido há três séculos, na cidade de Salem, promovido pela intolerância religiosa no interior de uma sociedade influenciada por normas puritanas. Busca-se compreender a ressignificação do termo feiticeira, por parte de Tituba, em um estudo fundamentado, sobretudo, nas noções de hibridismo e fronteira trazidas por Homi K. Bhabha em O local da cultura (2013). As discussões e produções científicas atinentes a este estudo têm sido elaboradas no âmbito do Projeto de Pesquisa Teseu, o labirinto e seu nome, vigente na Universidade Federal do Piauí.Palavras-chave: Maryse Condé: romance; construções identitárias negras americanas; Homi K. Bhabha: teoria; hibridismo; fronteira.
LIMA BARRETO: UM PINGENTE ENTRE A LITERATURA E A REALIDADE
Authors: Pasqual Camila Marcelina
Published: August 2019

O artigo, intitulado Lima Barreto: um pingente entre a literatura e a realidade, examina a forma como o escritor João Antônio retrata a vida do povo do subúrbio tentando resgatar a "voz" dos excluídos da periferia das grandes metrópoles e como tal tentativa de resgate determina a dinâmica de sua literatura. Ao mesmo tempo, avalia como a obra do romancista carioca Lima Barreto influenciou a produção literária do contista paulistano, levando-o a escolher retratar o mundo dos excluídos dos subúrbios: prostitutas, jogadores de sinuca e malandros, a partir da visão de mundo destes. Para tanto, o artigo utiliza as contribuições de autores como Antonio Candido, no que diz respeito à questão da literatura engajada, e Antonio Arnoni Prado para avaliar a influência de Lima Barreto sobre a produção contista de João Antônio. Prado também contribui para a análise da “herança” barretiana de João Antônio. O artigo recorre também às contribuições de Alfredo Bosi, sobre a afinidade de João Antônio e Lima Barreto para com as “classes excluídas”.Palavras-chave: João Antônio; Lima Barreto; Exclusão Social; Subúrbio; Processo de Urbanização
O ENTRE-LUGAR DOS DESAPARECIDOS POLÍTICOS EM K.RELATO DE UMA BUSCA E VOCÊ VAI VOLTAR PRA MIM E OUTROS CONTOS, DE BERNARDO KUCINSKI
Authors: Napp dos Santos Cristina , Fonseca Claudia Lorena
Published: August 2019

Este trabalho confronta três textos da produção literária do autor Bernardo Kucinski, K. Relato de uma busca, “O velório” e “Joana”. Além de compartilharem a característica de terem como pano de fundo a Ditadura Civil-Militar no Brasil, o romance e os dois contos abordam o drama dos familiares frente ao desaparecimento forçado dos militantes que se opunham ao regime. Retratam ainda o luto, a melancolia e de que forma a ausência do corpo interfere na concretização da morte no imaginário e nos rituais de luto. Ao propor uma análise interpretativa e comparativa do romance e dos contos, agregando as contribuições de Freud e Kristeva, bem como pesquisas antropológicas referentes a luto e rituais fúnebres, o artigo reflete acerca da importância do corpo para o processo de luto na cultura ocidental.Palavras-chave: Ditadura brasileira; desaparecimento forçado; luto; rituais fúnebres.
COLM TÓIBÍN: ENTRE ESPACIOS GEOGRÁFICOS Y DE LA MEMORIA EN THE HEATHER BLAZING
Authors: Arriaga Maria Isabel
Published: August 2019

En su estudio de la novela, Bakhtín considera a la heteroglosia como la principal característica de la prosa de ficción, dado que cada enunciación se produce en un momento histórico particular y en un entorno social específico. La novela, género literario dialógico por excelencia, se constituye por una pluralidad de voces y discursos sociales que representan distintas perspectivas del mundo representado en la obra literaria. En este marco, los conceptos de tiempo y espacio se fusionan en unidades de sentido inseparables que Bakhtín denomina “cronotopos”,  núcleos de representación esenciales de la obra. La novela The Heather Blazing (1992), del escritor y periodista irlandés Colm Tóibín, se estructura en torno a tres cronotopos: del encuentro, el umbral y la ruta, cuyo análisis permite explorar las ambigüedades que se producen en la Irlanda de 1990 durante su proceso de modernización y reorganización institucional. El propósito de este trabajo es analizar representaciones de Irlanda contemporánea y de reconstrucción identitaria en la novela de Tóibín, en torno a las categorías de tiempo-espacio e identidad, que se enmarca en el proyecto de investigación “Literatura irlandesa: estudios socio-críticos y traducción como diálogo intercultural”, de la Facultad de Ciencias Humanas, UNLPam. Los resultados preliminares de esta investigación permitirían avizorar la coexistencia del pasado y el presente en la Irlanda de los años ’90 y en la vida de los personajes de Tóibín, quienes -al igual que su nación- deben negociar valores en una sociedad fragmentada, aceptar el pasado y superar las pérdidas para re-inventarse hacia un futuro superador del pasado. Palabras claves: lugar; memoria; identidad; representaciones; literatura irlandesa.
