Published: March 2018

Hypsipyla grandella (Zeller) is a key forest pest in Latin America and the Caribbean, where it has precluded attempts to establish commercial plantations of mahoganies (Swietenia spp.) and cedars (Cedrela spp.). In the search for methods to manage its larvae, being both preventative and cost-effective, as well as based upon resources from tropical flora, the crude flower extract of angel's trumpet, Brugmansia candida Pers., as well as four partitions thereof (water, hexane, dichlorometane, and ethyl acetate), were tested for phagodeterrence. Laboratory bioassays involved increasing concentrations of the crude extract (0.1, 0.3, 1.0, 3.2 and 10.0 % w/v) as well as each one of the partitions (in accordance to the yield obtained from the partitioning process). A randomized complete block design, with four replicates, was used. H. grandella instar III larvae were exposed for 24 h to Spanish cedar (Cedrela odorata) leaf discs dipped into the respective treatment, after which disc consumption was measured. Strong phagodeterrence was detected at concentrations as low as 1.0 % y 0.122 % w/v for the crude extract and the hexane partitions, respectively. In addition, a single bioassay was performed to compare a single concentration (0.38 % w/v) of the alkaloid scopolamine, which reduced consumption in 90 % with respect to the controls. Also, mortality and sublethal effects were assessed in larvae exposed to the crude extract, the hexane partition and scopolamine, with no evidence for them, which confirmed their phagodeterrence. Moreover, the crude extract was submitted to a phytochemical screening by means of a number of qualitative tests, which showed that alkaloids, tannins, triterpenes and cumarins were the most important secondary metabolites. Finally, the presence of scopolamine was confirmed in both the crude extract and the hexane partition, by means of the gas chromatography-spectrometry (GC-MS) analytical method. It is recommended to prepare a formulation of scopolamine plus some adjuvants, in order to test its effectiveness under greenhouse conditions, as a first step to advance in the development of a commercial phagodeterrent.

Published: March 2018

In many parts of the world, forestry objectives are now shifting from focusing on maximum production to a wider perspective that includes biodiversity preservation and ecosystem functioning. To achieve these targets, managers are increasingly designing cutting regimes that imitate natural disturbances, with the aim of generating a more naturally structured forest. In many old-growth forests, tree fall gaps caused by tree death constitute the dominant type of disturbance. The application of gap dynamics theory appears to be a promising option for tropical forest management and conservation. In the present study of a tree species-rich and old-growth Ecuadorian Neotropical forest, we assessed the spatial distribution of gaps and gap size in relation to: i) tree number at the gap edge, ii) number of tree species at the gap edge, iii) number of tree species per stem at the gap edge, iv) species similarity, v) species evenness at the gap edge, vi) size differentiation at the gap edge, vii) gap isolation and viii) species mingling at the gap edge. Understanding natural gap processes in these forests is crucial for establishing new forestry practices in these forests to mimic natural processes of disturbance. Our results demonstrated that the spatial distribution of gaps was random. Various gap attributes were strongly associated with gap size. The number of tree species per stem at the gap edge was negatively correlated to the gap size. Gap sizes up to 50 m2 were mostly sufficient to generate tree species-rich forest stands. Assuming that our results were representative for an old-growth neotropical rainforest in Ecuador, our study remarks the following management recommendations: 1) Rainforests have a very complex spatial and diversity structure and logging activities should preferably be omitted because of adverse effects. 2) If logging is inevitable, this should mimic a random choice of trees and tree species, to prevent special selection of tree dimension and species; and a random distribution of trees to be logged, to produce gaps smaller than 50 m2 and never larger than 400 m2. Additionally, we suggest cutting not more than 5 % of the tree biomass per 10-20 years period, to preclude stronger alterations of ecosystem processes, and the reduction of existing dead wood from the ecosystem.
Eficiencia en el uso de trampas de caída y suficiencia taxonómica en comunidades de arañas (Araneae) epigeas en tres ecorregiones del Noroeste Argentino

Published: March 2018

The increased degradation of natural habitats has strengthened the need to know and assess biodiversity patterns. Particularly, the study of the araneofauna in the North of Argentina is scarce in ecoregions with priority interests of conservation. Generally, spiders are used as indicators to compare biodiversity patterns, and here we tested whether the spider family-level can act as a substitute of the species-level in biodiversity rapid assessments. For this, we analyzed the alpha and beta diversity of the epigeal spider communities in three separate sites of different ecoregions of Salta province (Chaco Serrano, Monte de Sierras and Bolsones, and Puna), during the fall, winter, spring and summer of 2005 -2007. In each site, 10 pitfall traps, located along a linear transect and 10 meters apart, were placed for seven days per season of continuous activity. Samples were obtained, taken to the laboratory and identified. A total of 886 spiders were collected from 100 species/morphospecies of 19 families. The completeness of the inventory obtained for each ecoregion surpassed 70 %. The Chaco ecoregion (S = 56, N = 495) reported the highest species richness and abundance compared to Monte (S = 44, N = 262) and Puna (S = 23, N = 129). Alpha and beta diversity showed that ecoregional spider communities were different, sharing between them very few species (0.7 %). The Chaco reported a high dissimilarity of its assemblage with respect to the other ecoregions. The colder seasons (autumn and winter) proved to be important in assessing the diversity of spiders in these ecoregions, contributing to regional diversity in conjunction with the diversity of warm seasons (spring and summer). Four guilds were reported (ground hunters, specialists, other hunters and ambush hunters), but the latter was absent in Monte, and the specialists dominated in Chaco. Zodariidae was dominant in Chaco Serrano, where Leprolochus birabeni is an indicator of native environments. On the other hand, Lycosidae, Philodromidae, Anyphaenidae and Oonopidae were important for Monte and Puna. This way, the use of pitfall traps in all seasons of the year, and the recognition of spider families for epigeal fauna, was very useful for biodiversity rapid assessments in this area. Like the species-level, the taxonomic family-level evidenced changes in alpha and beta diversity. This allowed the inclusion of this taxonomic group for future biodiversity monitoring studies for conservation plans in these ecoregions.
Distribución conocida y potencial de dos taxa del género Mimosa (Leguminosae) endémicos de México

Published: March 2018

Mimosa aculeaticarpa var. aculeaticarpa and M. luisana are endemic to Mexico, and are considered as multipurpose plants, due to the diverse services they offer to ecosystems and to local people. Additionally, they are appreciated for their potential to restore tropical environments; hence, the objective of this study was to model the present and potential distribution of these taxa. In 2014, species registers were obtained from two databases (CONABIO and MEXU); each register was taxonomically, geographically and statistically validated. Once validated, the present and potential distribution of M. aculeaticarpa var. aculeaticarpa (based on 99 registers) and M. luisana (based on 50 registers) were obtained using the MAXENT algorithm. For both taxa, the present distribution was overlapped using the layers of: elevation, climate, soil, biogeographic provinces, and hydrologic basins. Mimosa aculeaticarpa var. aculeaticarpa showed a wide distribution in Mexico (16 states); whilst M. luisana was restricted to the states of Puebla and Oaxaca. M. aculeaticarpa var. aculeaticarpa establishes between 1 900 and 2 700 masl, and M. luisana between 500 and 1 760 masl. Both species were established in arid and semiarid climates; however, M. aculeaticarpa var. aculeaticarpa can also be found in temperate and mesic climates. Moreover, both taxa are distributed in calcareous regosol soils; although, M. aculeaticarpa var. aculeaticarpa is also found in eutric regosol, chromic vertisol and haplic phaeozem. The distribution of M. aculeaticarpa var. aculeaticarpa includes eight biogeographic provinces and three hydrologic basins; whilst M. luisana was only located in three provinces and two hydrologic basins; both are present in the Eje Volcánico and Sierra Madre del Sur provinces. The potential distribution models are considered as excellent ones due to an AUC of 0.91 and 0.97, respectively; these models indicated that the temperature and precipitation conditions would be suitable for the enlargement of their distribution. Likewise, these models can be considered an approach to the potential distribution knowlegment of the Mexican mimosas. Nevertheless, it is important to note that the models are static and do not take into account any biotic interaction; therefore, their relationship with reality can vary. Thus, it is recommended to analyze the models through different climate change and land use scenarios.
Evaluating the effect of macroinvertebrate exclusion on leaf breakdown rates in two upland Colombian streams
Authors: Zúñiga-Céspedes Bladimir , Zúñiga María Del Carmen , Chará Julián
Published: March 2018

Macroinvertebrate shredders have been widely recognized as an important functional feeding group that contributes to leaf decomposition in temperate streams, but little is known about their role in upland Neotropical streams. In this study, we investigated the effect of macroinvertebrate exclusion on leaf breakdown rates in two upland streams (Marianela and Peña Bonita with 1 911 and 2 560 m elevation, respectively) in Colombia. We hypothesized that leaf litter breakdown is mediated mainly by macroinvertebrate shredders in Colombian upland streams. The study was carried out between January and April of 2009, including the dry season and the beginning of the wet season. We measured leaf mass loss using coarse- (15 mm; accessible to macroinvertebrates) and fine- (200 µm; macroinvertebrates excluded) mesh litter bags that were anchored with wood stakes to the bottom of each stream and recovered after 7, 14, 21, 28, and 56 days. We selected leaves from two dominant plant species and used three leaf treatments: two single species (Palicourea cuatrecasasii and Critoniopsis ursicola) and mixed-species (P. cuatrecasasii and C. ursicola). We compared leaf breakdown rates between the Peña Bonita and Marianela stream, mesh-sizes, and leaf treatments. Macroinvertebrates that colonized the litter bags were measured for density and biomass and categorized in functional feeding groups. In general, there were no significant differences in breakdown rates between the streams and the mesh-sizes. In contrast, leaf breakdown rates had significant differences between all leaf species, where C. ursicola had higher breakdown rates than mixed-species, and P. cuatrecasasii. Macroinvertebrate exclusion did not affect leaf breakdown rates and their assemblages were composed by high densities of collectors (mainly Chironomidae) and few shredders with a large body size. The similar macroinvertebrate colonization between leaf species, the relatively slow breakdown rates, and the shredder scarcity, suggest that leaves were a refractory substrate. Further studies should include leaf species with different nutritional qualities and larger spatial-temporal scales to test the hypothesis of shredder presence and its role on leaf decomposition in upland Colombian streams.
Variación en el patrón de coloración de Anablepsoides hartii (Cyprinodontiformes: Cynolebiidae) en arroyos costeros de Venezuela
Authors: Infante-Rivero Edwin
Published: March 2018

Anablepsoides hartii is a non-annual fish of the family Cynolebiidae. Historically, this species has presented some inconsistencies for proper identification, due to a variation in the color pattern. The aim of this study was to describe and illustrate the different types of color patterns found in this species. For this purpose, we examined a total of 336 preserved specimens (19 lots) deposited in the ichthyological collections of the Museo de Biologia de la Universidad Central de Venezuela and the Museo de Ciencias Naturales in Guanare, Venezuela. The specimens were sorted by distinctive characteristics of size, sex and locality. Besides, we took photographs of each individual, vectorized them with detail, separating light and dark colorations and delimited color patterns of the same tone with the program Corel Draw version x7 (Spanish). My analysis showed that A. hartii presented four colors patterns. The color morphs were classified as: 1 male, 2 female, 3 intermediate and 4 montane. The first two color morphs were separated by sexual characters (sexual dimorphism); in turn, the intermediate color morph presented characters of both males and females in the same individual. Finally, the montane color morph differed from the previous ones by presenting a series of incomplete lateral rows, followed by a half-body reticulation to the tail. This analysis allowed the identification of the differences in this morphologically variable species.
Los agroecosistemas cafetaleros modernos y su relación con la conservación de mariposas en paisajes fragmentados
Authors: Pérez-García Oscar , Benjamin Tamara J. , Tobar Diego Enrique
Published: March 2018

Land use change by the intensification of agriculture contributes to tropical forest fragmentation and biodiversity loss. In this sense, in comparison with traditional agroforestry systems (AFS), modern AFS are considered irrelevant for the conservation of biodiversity of tropical forest fragments. However, there is an increasing trend toward the establishment of different types of modern AFS. Owing to the sensitivity to environmental changes, we evaluated the biodiversity of butterflies in AFS with Coffea arabica and Erythrina poeppigiana (CP), and intermixed with Musa spp. (CPM) or Cordia alliodora (the only native species of AFS) (CPL), as well as premontane very humid forest fragments in the Volcánica Central-Talamanca Biological Corridor, Costa Rica. In six representative sites of each system we set up three parallel 80 m line-transects, separated by a distance of 25 m. Each coffee farm and forest fragment (FR) was surveyed during 1.5 hours to record butterflies. All sites were sampled once a month from May to July 2007. We obtained 4.5 hours of sampling/site, and 27 hours of sampling/habitat. Both CP and CPM together had a butterflies’ species composition which differed from CPL and FR. The indicator species of both CP and CPM together were Hermeuptychia hermes and Anartia jatrophae which are typical of open areas. CPL resulted with the species of secondary forests Heliconius erato petiverana and Pareuptychia ocirrhoe as indicators. In contrast, FR resulted with several indicator species typical of closed canopy forests such as Pierella helvina incanescens, Caligo eurilochus, and Morpho peleides limpida. Moreover, the richness of species was similar among coffee AFS. Furthermore, the richness of species of each coffee AFS was lower in comparison with FR. However, among coffee AFS, CPL harbored higher diversity (Exp(H’)) of forest butterflies than CP. Also, CPM was higher in abundance of frugivorous butterflies in relation with CP and CPL. In fragmented forests, coffee farms with exotic shade species combined at least with a native tree or fruit species, can be a better habitat for forest butterflies than those dominated by an exotic monospecific shade.

Significant amounts of economic resources are spent by poor countries for access to scientific information that is blocked by pay-walls, and when fees are corrected for local economies, they can be the equivalent of hundreds of dollars per article. Pay-walls, is controlled by a small group of companies in rich countries, block knowledge from the societies that need it most. These companies should adjust their fees according to local economies: this would be fairer and would benefit everyone, including the same companies.

We greatly appreciate the care and thought that is evident in the 10 commentaries that discuss our debate paper, the majority of which argued in favor of a formalized ICD-11 gaming disorder. We agree that there are some people whose play of video games is related to life problems. We believe that understanding this population and the nature and severity of the problems they experience should be a focus area for future research. However, moving from research construct to formal disorder requires a much stronger evidence base than we currently have. The burden of evidence and the clinical utility should be extremely high, because there is a genuine risk of abuse of diagnoses. We provide suggestions about the level of evidence that might be required: transparent and preregistered studies, a better demarcation of the subject area that includes a rationale for focusing on gaming particularly versus a more general behavioral addictions concept, the exploration of non-addiction approaches, and the unbiased exploration of clinical approaches that treat potentially underlying issues, such as depressive mood or social anxiety first. We acknowledge there could be benefits to formalizing gaming disorder, many of which were highlighted by colleagues in their commentaries, but we think they do not yet outweigh the wider societal and public health risks involved. Given the gravity of diagnostic classification and its wider societal impact, we urge our colleagues at the WHO to err on the side of caution for now and postpone the formalization.

Sources of Conflict in the Middle East: Borders or Stratified Identities?
Authors: Turan Kürşad
Published: March 2018

Abstract Since the end of Ottoman control, Middle

East has experienced a large number of conflicts. The arrangements made at the

end of World War I are often blamed for these conflicts. Arbitrarily drawn

borders and the creation of influence zones between Great Britain and France

without paying attention to religious and ethnic divisions present in the

region are seen at the source of today’s conflicts. Arangements such as the

Bunsen Committee report, Sykes-Picot agreement, and Hussein-McMahon

correspondence shaped the region after the war, but none of these were

successfully implemented due to changing circumstances, and their contradicting

nature. This study argues that even though these constituted the first step in

the creation of the modern Middle East, the real cause of today’s conflicts lie

in the creation of a stratified politicized identity system that emerged

through stages over the past century. These stages were marked by the conflicts

between Arab nationalism and nation state identities; the politicization of

sectarianism; and finally the emergence of ethnicity in politics. Keywords: Middle East, conflict, Sykes-Picot agreement, Arab nationalism,

sectarianism, ethnicity.

Risky Business: An Integrated Institutional Theory for Understanding High-Risk Decision Making in Higher Education
Authors: TURNER LAUREN A. , ANGULO A. J.
Published: March 2018

Lauren A. Turner and A. J. Angulo explore how institutional theory can be applied to explain variance in higher education organizational strategies. Given strong regulatory, normative, and cultural-cognitive pressures to conform, they ask, why do some colleges engage in high-risk decision making? To answer this, they bring together classic and contemporary approaches to institutional theory and propose an integrated model for understanding outlier higher education strategies. The integrated model offers a heuristic for analyzing external and internal pressures that motivate colleges to implement nontraditional strategies. Through an analysis of recent trends among outlier colleges and their approaches to the Scholastic Aptitude Test, Turner and Angulo contextualize the model and consider its potential for understanding why higher education organizations adopt characteristics that differentiate them from their peers.
My Future, My Family, My Freedom: Meanings of Schooling for Poor, Rural Chinese Youth
Authors: XIANG XIN
Published: March 2018

In this article, Xin Xiang investigates what dushu, or “schooling,” means for rural senior secondary school students in a high-poverty county in southwestern China. With the persistence of China's rural-urban education inequality and alarming reports about secondary school dropout rates, rural students' and their families' attitudes toward schooling have become a topic of academic as well as public debate. Drawing from repeated interviews with and observations of twenty-seven students conducted over a year, Xiang uses portraiture methodology to illustrate the different dimensions of meaning these rural youth attach to dushu: the means to a future of comfort and dignity, a family responsibility and collective investment, and a path toward individual freedom and actualization. This portrait also reveals the deep contradictions that define these students' experiences of dushu and how it often denies the hopes they attach to it and demands painful compromises.

have been investigated as theoretical. RHF/STO-3G method was used for quantum
calculations of chemical properties of these compounds. The structures of the
compounds were fully optimized and then the results were evaluated by this
method. The properties of compounds were presented and the utilization of these
compounds in various fields was investigated by comparison of theoretical
results with experimental ones. The experimental antioxidant effects were
reported previously. The quantum calculations revealed that chrysoeriol (2) was unstable and was prone to react
to the radical compounds. In brief, a good antioxidant can donate the electron
to the radical compound easily.

Published: March 2018

Introduction: During the aging process, significant changes in the pattern of distribution of morphological and structural variables such as body fat and muscle mass can be observed. Objective: To analyze the distribution of total and appendicular muscle mass in women in different age groups. Methods: The sample consisted of 129 women, aged between 50 and 80 years. The study was divided into two stages, composed of the anthropometric measures, total body mass (kg) and height (m) and body composition evaluation using DEXA. Results: There was a significant reduction in muscle mass with the advancement of age, and from age 60 and older, the age group showed a significant increase when compared to subjects of lower age, with a decrease of 1.65 kg in their total muscle mass. It should be noted that in our study, this progression increased in subjects older than 72 years, with a decrease of 2,10 kg in their total muscle mass. Conclusions: The reductions of muscle mass in the lower limbs presented greater amplitudes in comparison with the other regions of the analyzed human body, being an area with greater focus of analyzes with the objective of identifying and assisting the diagnosis of sarcopenia in future studies.

Published: March 2018

Background: Researchers have sought to evaluate the relationship between sociodemographic characteristics and life habits in maintaining the postural balance of specific populations. However, studies based on analyzing in detail the influence of these factors on this body function in pregnant women are scarce. Objective: To analyze the association between sociodemographic, obstetric, anthropometric and lifestyle characteristics and changes in postural balance in pregnant women. Method: Cross-sectional study carried out from February 2012 to March 2015 at the Federal University of Rio Grande do Norte (UFRN). The sample consisted of 263 pregnant women. Balance Master System® (NeuroCom, Clackamas, USA) was used for balance evaluation. The bivariate analysis was performed by applying the chi-square test (x2 ). Results: The results suggest that the absence of alterations in the variables related to static postural balance is associated with higher levels of education, higher income and age over 29 years (x2 = 4.73, P = 0.03). In addition, during the evaluation of the dynamic balance, it was verified that the absence of abnormalities is related to income higher than 4 minimum wages (x2 = 3.98, P = 0.04), while changes in lateral displacement were associated with lower body weight (up to 68 kg) (x2 = 12.2, P = 0.03). Conclusion: There is an association between sociodemographic characteristics, life habits and changes in the postural balance of pregnant women.

Vom Ästhetischen Werte der Grieschischen Kömodie. Publicado por Johann Biester no ano de 1794 no Berlinische Monatschrift [Revista mensal berlinense]. O texto foi publicado novamente no ano de 1822, com o título ligeiramente alterado para Vom künstlerischen Werte der alten griechischen Komödie [Do valor artístico da antiga comédia grega], nas Sämtliche Werke, as obras completas editadas pelo próprio Schlegel.  Esta tradução partiu do texto estabelecido pela edição crítica das obras completas de Friedrich Schlegel organizadas por Ernst Behler, a qual traz as duas variantes.

“Você é a Dora? Eu sou o Guimarães Rosa” – Encontros míticos do escritor mineiro com a poeta paulista Dora Ferreira da Silva
Authors: Souza Enivalda Nunes Freitas e
Published: March 2018

A proposta desse artigo é discorrer sobre uma vista de Guimarães Rosa à casa da poeta paulista Dora Ferreira da Silva e os desdobramentos desse encontro, como cartas do autor mineiro e dois poemas de Dora a Guimarães Rosa. A análise dos poemas revela a proximidade entre o pensamento dos escritores, sobretudo quanto à concepção do universo como unidade simbólica e à crença no poder fundante da língua. É pelo viés do mito – o mito de Orfeu – que a poeta se encontra, ainda uma vez, com Rosa em seu cavalo, agora em uma fotografia. O cavaleiro olhando para trás arrebata a poeta/Eurídice, em franca transposição dos espaços, resgatando o tempo primordial que a arte possibilita. O aporte teórico vem de entrevistas e obras dos dois escritores, além de estudos sobre mito de Mircea Eliade e Carl Gustav Jung.
Objetos míticos americanos: livros dos povos tradicionais e experiências de leitura da autoria indígena no Brasil
Authors: Barra Cynthia De Cássia Santos
Published: March 2018

Este ensaio é, basicamente, resultado de um projeto de pesquisa realizado durante os quatro anos que trabalhei como professora na Universidade Federal de Rondônia. O projeto, intitulado de “Livros da Floresta: do registro etnográfico à criação literária” (Edital Universal CNPq/2011), permitiu-me orientar oito estudantes do Curso de Letras como bolsistas do Programa de Iniciação Científica daquela instituição, com planos de trabalhos voltados para as literaturas de autoria indígena produzidas pelos povos Maxakali, Suruí Paiter, Kaxinawá, Yanomami, Dessana, Pataxó e Cinta Larga. Neste ensaio, analisamos especificamente três livros escritos, respectivamente, pelos Kaxinawá, pelos Dessana e pelos Maxakali, para, a partir desta experiência de leitura, problematizarmos as relações entre mito e literatura e os alcances de nossos modos de ler a autoria indígena na contemporaneidade.
A superfície persistente do começar: escrita-leitura em Maria Gabriela Llansol
Authors: Samudio Jonas Miguel Pires
Published: March 2018

Apresentamos, a partir de fragmentos de Inquérito às quatro confidências, de Maria Gabriela Llansol, uma reflexão acerca da escrita-leitura, partindo de uma articulação entre o texto llansoliano e o texto bíblico, sobremaneira o mito edênico. Objetivamos acompanhar o modo como o texto de Llansol estabelece um encontro com os dessa tradição para, não confirmando-os, confrontá-los e avançar na compreensão e na experiência da escrita-leitura como anterior a todos os inícios.
No limite do corpo: João Gilberto Noll e o fim da mitologia
Authors: Dusse Fernanda
Published: March 2018

A narrativa da novela O quieto animal da esquina evidencia a escrita esquizofrênica e violenta de João Gilberto Noll. A partir da narração feita por seu protagonista, o leitor é levado a percorrer caminhos errantes, capazes de demonstrar a incapacidade da linguagem na elaboração de signos que deem conta da experiência. Neste percurso, a presença de instituições que representam a solidez da cultura cede lugar para a violência e o silêncio, regentes das relações humanas. A partir dessa perspectiva, este trabalho objetiva discutir como o texto de Noll revê o espaço da mitologia, da história e da cultura na sociedade contemporânea, buscando evidenciar, a partir de imagens do escatológico e da violência, os desejos ainda pulsantes nos corpos das personagens.

Pós-modernidades: Breve explicitação da crítica de David Harvey a Jean-François Lyotard
Authors: Godinho Josué Borges de Araújo
Published: March 2018

Este breve texto tenta explicitar a crítica feita por David Harvey, em Condição pós-moderna, a Jean-François-Lyotard. O trabalho leva em consideração as leituras que ambos fazem da chamada “pós-modernidade”, tendo em mente, dentre outras coisas, a surpresa de Harvey diante do conceito de “justiça” apresentado por Lyotard e a problematização, por parte de Harvey, do fato da intensa fragmentação que se dá, sobretudo, a partir de 1970, além da questão da cumplicidade crescente entre o pós-modernismo e a estetização da política. O método de análise confronta os procedimentos de Harvey e Lyotard diante da pós-modernidade.
Será livro?
Authors: Pimentel Daiane Carneiro
Published: March 2018

Proponho-me a desenvolver uma leitura de Serafim Ponte Grande, de Oswald de Andrade, a fim de demonstrar que em tal obra a dimensão crítica pode ser verificada na problematização das noções de escrita, de romance e de livro. A princípio, serão abordados o modo como Serafim relaciona-se com a escrita e o fato de o protagonista planejar compor um romance. Em seguida, será analisada a unidade intitulada “O Merediano de Greenwich”, um “romance de capa e pistola” que, por meio da paródia, desconstrói práticas literárias e atinge material e textualmente a cultura livresca. Serafim Ponte Grande constitui-se, assim, como uma obra que tensiona seus próprios limites e que solicita de seu leitor uma postura interpretativa também pautada pela negatividade, isto é, pela recusa dos lugares-comuns da investigação crítica. Ao desdobrar a negatividade de Serafim Ponte Grande, pretendo explicitar elementos que fazem desta produção oswaldiana um não-livro.
Ainda há lugar para os clássicos na escola? O cânone e os documentos oficiais sobre o ensino de literatura
Authors: De Martini Marcus
Published: March 2018

O presente artigo busca analisar a situação do estudo dos “clássicos” na escola, entendendo-se o termo primeiramente como referente às obras compostas entre os séculos XVI e XVIII e, num segundo momento, estendendo-o às obras “relevantes” escritas em qualquer tempo. Com base em pesquisas recentes, como Fischer et alli. (2012) e Fischer (2014), o artigo discute a posição do “cânone” no ensino de literatura brasileira na escola, analisando-se, para isso, os documentos oficiais sobre o ensino de literatura, bem como o Exame Nacional do Ensino Médio (ENEM) e o Programa Nacional Biblioteca da Escola (PNBE). A partir dessa análise, constatou-se um progressivo apagamento desse tipo de produção literária, cujas implicações são aqui discutidas. Conclui-se então que é preciso se repensar o lugar dos “clássicos” na escola, promovendo-se a formação do leitor com políticas mais consistentes e coerentes com os objetivos que se espera do ensino de literatura.
Na confluência da prosa e da poesia: "Niketche", um romance lírico
Authors: Santos James Rios de Oliveira , Tofalini Luzia Aparecida Berloffa
Published: March 2018

Niketche: uma história de poligamia é um romance contemporâneo, publicado em 2002 pela autora moçambicana Paulina Chiziane. O seu conteúdo temático é daqueles cujo vigor narrativo (e poético), cujo encadeamento dramático e cuja transparência dos fatos ensejam uma boa discussão sobre a situação da mulher negra, inserida em um espaço pós-colonial, logo, tensionalmente antidemocrático, onde é possível observar os mecanismos da dominação masculina se inscrevendo nos corpos dos sujeitos por meio de vias simbólicas, conforme Bourdieu (2005). Essa reflexão, sobre a supremacia patriarcal, é o ponto de partida para análise da obra em tela sob o prisma do romance lírico, pois a predominância da linguagem poética – emergente da angústia da protagonista –, bem como a presença de outros elementos estruturais de natureza lírica, sugerem um enquadramento do texto nessa perspectiva classificatória. Fundamentam esta discussão: Bourdieu (2005) e Bakhtin (1998), dentre outros teóricos e críticos que se debruçam sobre o assunto.

Leia mulheres: Literatura, empoderamento e divulgação da autoria feminina em Goiânia
Authors: Lousa Pilar Lago e , Santos Maria Clara Dunck
Published: March 2018

Em Um teto todo seu, Virginia Woolf denuncia as limitações de gênero que têm excluído as mulheres do ofício literário. Para descortinar a participação destas na construção da história, surgem iniciativas de resistência ao monopólio intelectual masculino, como o Leia Mulheres, clube de leitura brasileiro fundado a partir da ação #readwomen2014. Incentivar a leitura de obras escritas por mulheres, estimular o aumento da participação delas na literatura e contribuir para uma reorientação do mercado editorial são alguns dos objetivos da iniciativa. Este artigo realiza uma leitura acurada da atuação do Leia Mulheres de Goiânia, em 2016, a fim de verificar as experiências trocadas no clube e de que maneira sua existência pontua questões que permeiam não apenas a relação dos participantes com as obras lidas, mas também o lugar da literatura de autoria feminina, sua importância e resistência em uma sociedade excludente. PALAVRAS-CHAVE: autoria feminina; empoderamento de mulheres; leia mulheres; clube de leitura.
Применение технологий ревеню-менеджмента в индустрии международных авиаперевозок
Authors: Костин Константин Борисович , Полынцев Павел Сергеевич
Published: March 2018

Представлен сравнительный анализ европейского рынка авиаперевозок. На основе данных о деятельности европейской бюджетной авиакомпании EasyJet и ее конкурентов выявлены отличия в функционировании традиционных авиаперевозчиков и лоукостеров. Установлено, что при прочих равных условиях бюджетные авиакомпании стремятся в первую очередь к максимальной загрузке своих самолетов с целью максимизации доходов. Выявлено, что в условиях эластичного спроса максимизация загрузки становится возможной благодаря применению методов и технологий ревеню-менеджмента, которые позволяют динамически устанавливать цены в соответствии с требованиями рынка. Проанализированы принципы ценообразования в области международных авиаперевозок.
