Authors: yang chen , Geng WeiLian , Hu Jianying , Huang Shaoqiang
Published: April 2019

Background: Previous studies have shown that patients with long-term diabetes require more opioids after surgery than patients without diabetes. Gestational diabetes mellitus (GDM) normally only lasts for a brief period; nevertheless, its effect on sufentanil consumption after cesarean section is unknown.
Methods: This prospective cohort study included two groups: a GDM group (n=32) and a matched non-GDM (NGDM) group (n=32). All patients underwent routine combined spinal-epidural anesthesia for cesarean delivery. Sufentanil consumption through an intravenous patient-controlled analgesia (PCA) pump, the frequency of PCA requests, and visual analog scale (VAS) scores 6 and 24 hours after surgery were compared between groups.
Results: Sufentanil consumption (µg) 6 hours after surgery was higher in the GDM group than in the NGDM group (24.0±6.6 vs 20.1±5.7, P=0.023). PCA was used more frequently 6 and 24 hours after surgery by the GDM group than by the NGDM group (1[0-2] vs 0[0-1], P=0.001; 6[4-8] vs 3[1-5], P=0.001, respectively). The VAS score during activity 24 hours after surgery was higher in the GDM group than in the NGDM group (5[5-6] vs 5[4-5], respectively, P=0.03).
Conclusion: Pregnant women with GDM require more opioids during the immediate postoperative period after cesarean section than those without GDM.
Freesia Responds to Preplant Flurprimidol and Paclobutrazol Corm Soaks
Authors: Miller William B.
Published: April 2019

Experiments conducted over 3 years have indicated the efficacy of preplant paclobutrazol or flurprimidol corm soaks for leaf and scape growth control in potted freesia (Freesia hybrida). A range of cultivars subjected to 30- to 60-min soaks in 60 to 120 mg·L−1 paclobutrazol and 10- to 30-min soaks in 10 to 30 mg·L−1 flurprimidol resulted in significant and commercially relevant height control without reducing the number of flowering scapes. Cultivars varied in their response to the plant growth regulators (PGRs), suggesting that individual grower trials will be necessary to develop an optimum treatment for each location.
Phenotypic Association of Multi-scale Architectural Traits with Canopy Volume and Yield: Moving Toward High-density Systems for Macadamia
Authors: Toft Benjamin D. , Alam Mobashwer M. , Wilkie John D. , Topp Bruce L.
Published: April 2019

The vigorous growth and large canopy size of commercial macadamia (Macadamia integrifolia, M. tetraphylla, and hybrids) cultivars generally restricts macadamia orchards to low-density planting. Little is known of the detailed interactions between plant architecture and yield components specific to macadamia. This chapter examines how dependent traits such as canopy size and yield might be determined by direct and indirect interactions between traits at different scales within the canopy. Fifteen genotypes (n = 3) were phenotyped in two growing seasons for architectural and reproductive traits, around the age of their transition from juvenility to maturity. Genotypes varied in canopy volume, cumulative yield, and canopy efficiency, and particular genotypes with low canopy volume and high yield were considered potentially useful for future high-density orchard systems. There was high variability in architectural, floral, and yield traits at multiple scales. Direct and indirect effects of architectural traits on the variability of yield and tree size were quantified using path coefficient analysis. Canopy volume was subject to positive direct effects from trunk cross-sectional area (TCA; 0.72), lateral branching (0.24), and branch unit (BU) length (0.24). Other traits showed significant indirect effects with canopy volume via TCA, such as branch cross-sectional area (BCA; 0.43), BU length (0.40), lateral branching (0.35), and internode length (0.32). Branch angle had a significant indirect negative effect on canopy volume via BU length (−0.11). Nut number had the strongest direct effect on yield (0.97), and this relationship was significantly indirectly influenced by raceme number (0.47), raceme length (0.50), nut number per raceme (0.33), canopy volume (0.37), and branch angle (0.35). In these relatively young trees, early yield was directly and positively influenced by canopy volume (0.12), presumably due to increased early light interception, which suggests that early canopy vigor contributes to early yield. This study suggests that yield and canopy size are determined by complex phenotypic interactions between architectural traits at different scales. Therefore, preplanting (i.e., scion and rootstock selections) and postplanting (i.e., pruning and training) manipulations that specifically manage architectural traits such as shoot length, branching, branch angle, raceme length, and nuts per raceme may result in the creation of efficient macadamia canopies.
Comparison of Sole-source and Supplemental Lighting on Callus Formation and Initial Rhizogenesis of Gaura and Salvia Cuttings
Authors: Owen W. Garrett , Lopez Roberto G.
Published: April 2019

Variability in outdoor daily temperatures and photosynthetic daily light integrals (DLIs) from early spring to late fall limits the ability of propagators to accurately control propagation environments to consistently callus, root, and yield compact herbaceous perennial rooted liners. We evaluated and compared the effects of sole-source lighting (SSL) delivered from red (R) and blue (B) light-emitting diodes (LEDs) to supplemental lighting (SL) provided by high-pressure sodium (HPS) lamps on herbaceous perennial cutting morphology, physiology, and growth during callusing and initial rhizogenesis. Cuttings of perennial sage (Salvia nemorosa L. ‘Lyrical Blues’) and wand flower (Gaura lindheimeri Engelm. and A. Gray ‘Siskiyou Pink’) were propagated in a walk-in growth chamber under multilayer SSL provided by LEDs with [R (660 nm)]:[B (460 nm)] light ratios (%) of 100:0 (R100:B0), 75:25 (R75:B25), 50:50 (R50:B50), or 0:100 (R0:B100) delivering 60 µmol·m−2·s–1 for 16 hours (total DLI of 3.4 mol·m−2·d−1). In a glass-glazed greenhouse (GH control), cuttings were propagated under ambient solar light and day-extension SL provided by HPS lamps delivering 40 µmol·m−2·s–1 to provide a 16-hour photoperiod (total DLI of 3.3 mol·m−2·d−1). At 10 days after sticking cuttings, callus diameter and rooting percentage were similar among all light-quality treatments. For instance, callus diameter, a measure of growth, of wand flower cuttings increased from an average 1.7 mm at stick (0 day) to a range of 2.7 to 2.9 mm at 10 days after sticking, regardless of lighting treatment. Relative leaf chlorophyll content was generally greater under SSL R75:B25 or R50:B50 than all other light-quality treatments. However, stem length of perennial sage and wand flower cuttings propagated under SSL R50:B50 at 10 days were 21% and 30% shorter and resulted in 50% and 8% greater root biomass, respectively, compared with those under SL. The herbaceous perennial cuttings propagated in this study under SSL R50:B50 were of similar quality or more compact compared with those under SL, indicating that callus induction and initial rooting can occur under LEDs in a multilayer SSL propagation system.

Published: April 2019

Pteroceltis tatarinowii Maxim, the only species of the genus Pteroceltis (family Ulmaceae), is an endemic rare tree species in China. This study was performed to explore vegetative propagation techniques for P. tatarinowii using stem cuttings. First, the effects of exogenous indole-3-butyric acid (IBA) and cutting positions on rooting performance were investigated to screen the appropriate exogenous auxin treatment and to determine the proper cuttings type. The results showed that the control cuttings pretreated with no exogenous IBA, irrespective of whether the stem cuttings were terminal, middle, or basal, rooted in a manner significantly inferior to that of cuttings pretreated with IBA. Their rooting percentage was less than 50%. Among the IBA-treated cuttings, the middle cuttings pretreated with 1000 mg·L−1 IBA rooted best, with the shortest number of days until rooting emergence (20 days), the highest rooting percentage (84.0%), the lowest mortality rate (4.0%), the greatest root number (average of 6.7 per cutting), and the longest roots per cutting (44.4 cm per cutting). Terminal cuttings pretreated with 1000 mg·L−1 IBA acquired satisfactory rooting traits and had the same shortest rooting duration (20 days) and the following parameters: rooting, 70.7%; mortality, 10.7%; average roots per cutting, 5.2; and longest root, 29.1 cm. To further determine the optimum cutting propagation time for this plant, a second experiment was performed and the cuttings were collected beginning in early June, when the growth of the current season was feasible for harvesting cuttings. Stem cuttings collected in late June and middle July had significantly higher rooting percentages (≥80%) compared with those collected in early June (66.7%). The other three rooting parameters were not significantly affected by the collection date. However, according to the overall rooting traits, the cuttings collected in both late June and middle July remarkably outperformed those collected in early June regarding the number of roots and the total root length per cutting. The initial nutrient reserves in the cuttings were also determined. A significant difference in the soluble carbohydrate level was found among collection times, but the nitrogen level in the cuttings was similar. The study revealed that stem cutting propagation of P. tatarinowii was achievable, and it was best achieved with cuttings collected from the terminal and middle positions of the branches of the current season from late June to middle July and treated with 1000 mg·L−1 IBA using the quick dip method.

Published: April 2019

Methyl bromide (MeBr) was identified as a stratospheric ozone depletory; therefore, the use of MeBr was phased out in the United States in 2005. Chloropicrin (CP) and allyl isothiocyanate (AITC) are MeBr replacements. A mixture of CP and AITC is commonly applied to broaden the pest control spectrum. These two fumigants have low soil mobility; however, their efficacy could be improved if their soil mobility were enhanced. This research was conducted to study the effects of surfactants applied at 5% (v/v) for CP mobility and AITC mobility in soils. Mobility of the CP/AITC mixture applied with a nonionic surfactant comprising oleic, linoleic, and palmitic acids (nonionic-1) and mobility of the CP/AITC mixture applied with a nonionic surfactant comprising C9 hydrocarbon aromatics and calcium alkylarylsuphonate (nonionic-2) were compared with mobility of the CP/AITC mixture applied without surfactants in three soils (Elder sandy loam, Chualar loam, and Blanco clay loam) during a laboratory study. Nonionic-1 surfactant increased the concentration of total leachate collected for AITC by five and CP by 11 compared with CP/AITC applied alone. Surfactants may influence the fumigant mobility in soil by affecting the sorption/desorption equilibrium. Our research suggested that increased AITC mobility and CP mobility in soil with the addition of adding nonionic-1 surfactant may be due to the adsorption behavior of the surfactant in the soil and the solubilizing capability of the surfactant with pesticides.

Camu-camu is an native species in domestication processes. Therefore, studies related to the root system are necessary to evaluate the best cultivation practices for an orchard. Two trials were conducted, one with nitrogen (N) and the other with potassium (K), at doses of 0, 40, 80, 160, and 320 kg·ha–1. Root distribution was determined using nondestructive analyses in which two-dimensional (2D) root images were obtained from trenches under the plants’ canopy. Variables included width (measured in cubic millimeters), area (measured in square millimeters), and length (measured in millimeters, and were analyzed using Safira software (version 2010, Embrapa, Brazil). To have better spatial visualization of variable distribution in the soil profile, data were analyzed using the ordinary kriging technique with the geoR software package and R software (version 2016). Both N and K doses influenced positively the camu-camu root system with regard to length, volume, and area. Better root distribution was verified with 80 kg·ha−1 N and 160 kg·ha−1 K doses. The nondestructive analysis via 2D images allowed sound characterization of root spatial distribution.

Published: April 2019

A wind turbine works under variable load and environmental conditions because of which failure rate has been on the rise. Failure of a gearbox, an integral part of producing wind energy, contributes to 80 % of the total downtime for the wind turbine. For ensuring better utilization of the wind turbines, Fault prognosis and condition monitoring of bearings are of utmost importance as it helps to reduce the downtime by early detection of faults which further increases the power output. In this paper, vibration signals produced and machine learning approach to determine the Remaining Useful Life (RUL) for a degraded bearing is studied. The methodology includes statistical feature extraction analysis with regression models. Further the feature selection is done using Principal Component Analysis (PCA) technique which produces training and testing sets which acts as an input parameter for regression models such as Support Vector Regressor (SVR) and Random Forest (RF). Weibull Hazard Rate Function is used for calculating the RUL of the bearing. Results This study shows the potential application of regression model as an effective tool for degradation performance prediction of bearing.

The knowledge of the hydrodynamic fluid response on the solid domain of structure contributes to reliability and earthquake resistance of liquid-containing systems. This paper presents the possibility of simulation endlessly long fluid filled the rectangular tank – channel due to an action of horizontal ground motion. The Finite Element Method was used for simulation of this problem. One computational model uses FEM formulation ALE FSI and two models simulate only the solid domain by FEM and fluid effect due to horizontal ground motion is simulated by fluid-quasistatic hydrodynamic pressure given by Eurocode 8 and Indian standard.
Seismic isolation effect of foamed concrete layer along the longitudinal direction of a mountainous tunnel
Authors: Li Can , Chen Weizhong
Published: April 2019

Foamed concrete is widely used in seismically isolated tunnels. As a linear underground structure, research on seismic isolation of the tunnel along the longitudinal direction is very important. However, few studies have been conducted on the seismic isolation effect of foamed concrete layer along the longitudinal direction of mountainous tunnels. To study the seismic isolation effect of foamed concrete layer along the longitudinal direction of a mountainous tunnel, the crushable foam plasticity constitutive model with volumetric hardening was adopted to simulate the volumetric hardening and rate dependence behavior of foamed concrete. Then, the three-dimensional finite element model is used to analyze the seismic isolation effect of the foamed concrete layer. The results show that the foamed concrete layer absorbs shear strain that is transmitted from the surrounding rock, through its own shear deformation, reducing the influence of the surrounding rock deformation on the tunnel lining.

Published: April 2019

In terms of resource transportation, pipelines play a very important role, however, it’s leakage is almost inevitable, so leakage monitoring has always been a research hotspot. The leakage identification of water supply pipeline is studied in this paper. The vibration caused by turbulence and cavitation at the leak point has chaotic characteristics, and the spectral distribution of which has its own special area. Chaos can be judged by the Lyapunov exponent, this means that the occurrence of the leak is judged. By this method, the leakage can be effectively identified. The above theory is verified by experiments in this paper.

Relevance. Allogeneic hematopoietic stem cell transplantation (HSCT) is the only effective treatment method for the majority of patients with juvenile myelomonocytic leukemia (JMML). The authors of the article presented the experience of conducting HSCT in patients with JMML in the Russian Children’s Clinical Hospital.

Materials and methods. 55 HSCT for the period from 2003 to 2019 were performed in forty-two patients with JMML. 14 (33.3 %) patients from a related HLA-identical donor were given primary HSCT, 1 (2.4 %) from a related 9/10 HLA-compatible, 16 (38.1 %) – from unrelated HLA-identical, 6 (14.3 %) – from unrelated 9/10 HLA-compatible, 5 (11.9 %) – from haploidentical. The source of hematopoietic stem cells (HSC) in primary HSCT for 22 (52.4 %) patients was bone marrow (BM), for 13 (31.0 %) – peripheral blood stem cells (PBSC), for 4 (9.5 %) – cord blood (CB), for 3 (7.1 %) – BM in combination with CB. Twenty-two (52.4 %) patients received a myeloablative busulfan-containing conditioning regimen, 20 (47.6 %) – treosulfan-containing.

Results. The overall survival (OS) of patients for the entire observation period was 53 ± 8.3 %; transplantation lethality (TL) – 21.2 ± 6.8 %, relapse-free survival (RFS) – 72.0 ± 7.7 %, event-free survival (EFS) – 49.4 ± 7.8 %. The factors negatively influencing the results of HSCT in patients with JMML were the progression of the underlying disease at the time of HSCT, incomplete compatibility of the HSC donor, the use of CB as a source of HSC.

Conclusion. Indicators of OS, RFS, EFS patients with JMLL after HSCT are low. The reasons for treatment failure are TL, graft failure and relapse after transplantation. To improve the results of treatment of patients with JMML, careful selection of the donor and the source of HSC, the maximum possible reduction in the toxicity of conditioning regimens is necessary.

BACKGROUND

Specialty consultation is a critical aspect of an emergency department (ED) practice, and a delay in providing consultation might have a significant clinical effect and worsen the ED overcrowding. Although mobile electronic medical records (mEMR) are being increasingly utilized and are known to improve the workflow of healthcare providers, limited studies have evaluated its effectiveness in real-life clinical scenarios.

OBJECTIVE

We aimed to determine the association between response duration to ED specialty consultation request and frequency of mEMR use.

METHODS

This retrospective study was conducted in an academic ED in Seoul, South Korea. We analyzed EMR and mEMR data from May 2018 to December 2018. Timestamps of ED consultation requests were retrieved from the PC-based EMR, and the response interval was calculated. Doctors’ log frequencies were obtained from the mEMR. We merged both data using doctors’ de-identification numbers. Pearson’s product-moment correlation was performed to identify this association. The primary outcome was the relationship between the frequency of mEMR usage and time interval from ED request to the completion of the consultation by specialty doctors. Secondary outcome was the relationship between the frequency of specialty doctors’ mEMR usage and the response time to consultation requests.

RESULTS

A total of 25,454 consultations requests were made for 15,555 patients, and 271 specialty doctors provided ED specialty consultations. Of the 742 doctors who used the mEMR, 212 doctors used mEMR in specialty consultation process. According to the mEMR usage pattern, the average usage frequency of all users was 13.3/day, and the average duration of the completion of the specialty consultation was 51.0 min. For 21,885 completed consultations, there was a significant inverse relationship between the frequency of mEMR usage and time interval from ED request to consultation completion by specialty doctors. (Coefficient: -0.19 (-0.32 to -0.06), P<.01) Of 23,692 consultations had response time stamp among inclusions. There was also a significant inverse relationship between the frequency of specialty doctors’ mEMR usage and the response time to consultation requests (coefficient: -0.17 (-0.30 to -0.04), P=.01).

CONCLUSIONS

Our findings suggest that frequent mEMR usage is associated with quicker response time to ED consultation requests.
The English in Ghana: British, American or Hybrid English?
Authors: Okoh Harriet
Published: April 2019

As a result of colonization of the British, the English used in many African countries and for that matter Ghana, is the British standard variety. However, the English used in Ghana, appears to have been invaded by the American English. This poses a problem as both teachers and students especially at the senior high school level confuse themselves about which word or spelling is right and vice versa. This study thus seeks to investigate students’ awareness of this invasion, the extent of the invasion and also to ascertain which of the aspects of the language has been much influenced by the American variety. The underpinning framework for this study is Kachru’s (1985) concentric model to situate the type of English used in Ghana. A sample size of 100 Students of English Education Department of University of Education, Winneba was selected for the study. The data was a secondary one: a random collection of vocabulary. Test, interview and questionnaire were also employed to gather other related data for the study. Both qualitative and quantitative approaches were used to analyse the data with precedence on qualitative analysis and the findings were thematically presented. The results indicate that although students use both American and British English together, they have little knowledge about the differences between them, especially, with the vocabulary aspect. Students have fair knowledge about the differences between the two varieties as regards the orthography aspect. These findings have implications on the teaching of English language and on examination issues in the country. It also informs writers of various educational materials about what variety to use.

Os aspectos relacionados à polifonia têm encontrado um lugar privilegiado nos estudos linguí­sticos. Esse tema ganha ainda mais relevância quando se trata da mescla de gêneros, principalmente no âmbito da literatura. Neste trabalho, temos o objetivo de analisar a canção "Cigarro de Paia", que foi interpretada por Maria Bethânia após a citação de um trecho do conto "Barra da vaca", de Guimarães Rosa. A análise sustenta-se, em geral, no conceito de polifonia e, em particular, na relação desse conceito com algumas categorias teórico-analí­ticas do Modelo Modular de Análise do Discurso. Demonstramos por meio deste trabalho que a intérprete Maria Bethânia reorganiza o discurso da canção, interferindo na proposta de significação, o que evidencia como um sujeito explora a polifonia para obter novos efeitos de sentidos.

Published: April 2019

O presente trabalho verificou o ní­vel de leitura literária dos alunos do primeiro ano do Ensino Médio, em uma escola estadual do municí­pio de Dourados/MS. Diante da constatação de que tais alunos não conseguiam realizar leituras em sala de aula com a proficiência esperada, buscou-se averiguar o ní­vel de leitura consorciado ao processo de letramento, utilizando como suporte o gênero conto literário. O trabalho foi dividido da seguinte forma: 1) levantamento bibliográfico e documental, a partir de autores como Soares (2014), Zilberman e Silva (2008), Cosson (2009) , Cortázar (1993), dentre outros, para o referencial teórico; 2) leitura do conto "Natal na Barca", juntamente com os alunos; e 3) aplicação de questionário interpretativo. Contrariando a hipótese dos Parâmetros Curriculares Nacionais (PCNs), a análise demonstrou que esses alunos ingressam no Ensino Médio apenas decodificando textos, sem a proficiência em leitura esperada e sem conseguir realizar plenamente o processo interpretativo.
Operational relevance of resource theories of quantum measurements
Authors: Oszmaniec Michał , Biswas Tanmoy
Published: April 2019

For any resource theory it is essential to identify tasks for which resource objects offer advantage over free objects. We show that this identification can always be accomplished for resource theories of quantum measurements in which free objects form a convex subset of measurements on a given Hilbert space. To this aim we prove that every resourceful measurement offers advantage for some quantum state discrimination task. Moreover, we give an operational interpretation of robustness, which quantifies the minimal amount of noise that must be added to a measurement to make it free. Specifically, we show that this geometric quantity is related to the maximal relative advantage that a resourceful measurement offers in a class of minimal-error state discrimination (MESD) problems. Finally, we apply our results to two classes of free measurements: incoherent measurements (measurements that are diagonal in the fixed basis) and separable measurements (measurements whose effects are separable operators). For both of these scenarios we find, in the asymptotic setting in which the dimension or the number of particles increase to infinity, the maximal relative advantage that resourceful measurements offer for state discrimination tasks.

Published: April 2019

Como os cidadãos percebem as práticas dos policiais civis? Esses entendimentos têm alguma conexão com o conceito de direitos humanos? Em que medida os cidadãos creditam à Polícia Civil importante papel na materialização da ideia de direitos humanos, entendidos como “mecanismos capazes de prover tratamento igual aos diferentes, universalizando a aplicação da lei às distintas identidades que se especificam no espaço público” (KANT DE LIMA, 2004)? Para responder a essas questões foram utilizadas informações (dados quantitativos e qualitativos) coletadas no âmbito da III Semana de Visitas a Delegacias de Polícia (2009). A partir dessas informações, este artigo discute em que medida as práticas dos policiais civis, no Brasil, se coadunam ou não com o que se entende por direitos humanos no cenário atual.
O GOVERNO LULA E AS POLÍTICAS PÚBLICAS DO SETOR ELÉTRICO
Authors: Pase Hemerson Luiz , Rocha Humberto José
Published: April 2019

Este artigo analisa as políticas públicas de infraestrutura do setor elétrico no período de 2003 a 2010 quando as duas gestões presidenciais no Brasil estiveram a cargo de Luís Inácio Lula da Silva do Partido dos Trabalhadores – PT. A análise de políticas públicas é utilizada como instrumental teórico e metodológico para interpretar as opções teóricas orientadoras e o método de implantação da política energética contemporânea no Brasil. Neste sentido discute-se a trajetória histórica da produção energética brasileira, destacando a herança dos governos militares, bem como a mudança / reforma do papel do Estado empreendido a partir da redemocratização e, principalmente, pela mão dos governos Collor/Itamar (1990–1994) e FHC (1995-2002). O problema de pesquisa investiga a configuração do modelo energético brasileiro a partir de uma gestão federal comandada por um partido político de centro esquerda constituído fortemente vinculado aos movimentos sociais e sindicais críticos das relações de produção capitalista. As conclusões indicam que as políticas públicas de infraestrutura e do setor elétrico no governo Lula não rompem com a perspectiva reformista do Estado, aprofundando sua materialização em razão da necessidade de manter a credibilidade externa e a governabilidade interna.

O regime internacional de mudanças climáticas apresenta peculiaridades em seu período de formação que são interessantes para o estudo das Relações Internacionais, pois envolve alguns dilemas de cooperação em uma arena multilateral como o número de atores (estatais e não estatais), além da presença de instituições e organizações internacionais. A dinâmica de formação deste regime de impacto global auxilia na análise quanto ao multilateralismo e seus problemas de cooperação. O regime está inserido tanto em problemas de colaboração como de coordenação no que tange aos desafios de sua arena multilateral.
POLÍTICA EXTERNA DO GOVERNO LULA: COALIZÕES AO SUL COMO ALTERNATIVA MULTILATERAL
Authors: Ferreira Walace
Published: April 2019

Este artigo aborda as alternativas ao Sul estabelecidas pela política externa do governo Lula, tais como a formação do G-20, a constituição do IBSA, o significado dos BRICS, a defesa do regionalismo e a aproximação com a África. O objetivo aqui é identificar estas coalizões, por um lado, como estratégia de política externa do atual governo, e por outro, como resultado da atual configuração das relações internacionais pós era bipolar. Com relatos de ações da política externa mostro como, no multilateralismo em vigor, novas alternativas são propostas pelos países emergentes, buscando ampliar seus poderes de decisão nos principais fóruns internacionais. Neste contexto, a atuação do Brasil tem sido de fundamental relevância.
Movimento da Legalidade (1961): Resgatando o protagonismo de Mauro Borges
Authors: Pires Favaro Tereza Cristina
Published: April 2019

O objetivo desta comunicação é resgatar o protagonismo do Governador Mauro Borges no Movimento da Legalidade. Com a renúncia de Jânio Quadros em 1961, os ministros militares tentaram impedir a posse de João Goulart, o que desencadeou uma ampla mobilização, dentro e fora do Congresso, com vistas a assegurar a ordem Constitucional. Inicialmente, dois governadores - Mauro Borges (GO) e Leonel Brizola (RS) – insurgiram-se  contra o golpe e se colocaram, em seus estados, dispostos a resistir pacífica ou militarmente, se fosse o caso, até as últimas conseqüências, em defesa da Constituição. Isso leva a deflagrar o Movimento da Legalidade. A participação de Mauro Borges foi expressiva; com larga experiência em estratégias militares, elaborou um plano minucioso e tático, inclusive de logística, aventando a possibilidade de um confronto armado contra as forças golpistas. Face às pressões, como saída conciliatória instituiu-se o parlamentarismo, e João Goulart toma posse como presidente do Brasil (1961). No entanto, os desdobramentos políticos levam Mauro Borges a apoiar o golpe que levou a deposição de João Goulart do poder, em 1964.
A constituição das memórias sobre a repressão da ditadura: o projeto Brasil: Nunca Mais e a abertura da Vala de Perus
Authors: Teles Janaina Almeida
Published: April 2019

A transição brasileira para a democracia ocorreu sem rupturas evidentes. Sob a forte presença do legado ditatorial, a reconstituição factual e a reflexão crítica acerca do período autoritário permeiam-se por zonas de silêncio e interdições. A formação da memória sobre a repressão da ditadura teve dois eventos fundamentais, a publicação do projeto “Brasil: Nunca Mais” e a abertura da vala de Perus. O principal objetivo deste estudo é oferecer um panorama reflexivo sobre a interdição do passado recente, estabelecendo uma narrativa sobre a formação da memória social a partir destes momentos 'fundacionais', que empurraram os limites de transição pactuada a que o país assistiu. O panorama oferecido beneficia-se de entrevistas com pessoas diretamente envolvidas nestes eventos, documentos pouco explorados (i.e., anais da CPI da vala de Perus) e uma ampla revisão da bibliografia existente sobre o assunto.
O tempo da notícia: cidade, ditadura e redemocratização nas páginas de O Estado (Florianópolis, SC, 1964-1985)
Authors: Lohn Reinaldo Lindolfo
Published: April 2019

Este artigo aborda as relações entre as narrativas elaboradas no jornal O Estado, de Florianópolis (SC), as mudanças socioculturais ocorridas na cidade e os processos políticos ligados à ditadura militar e aos primeiros anos da recente redemocratização do Brasil. O discurso jornalístico mostra-se como um organizador do social, o que inclui a definição sobre o que deve ser lembrado ou esquecido. Narrativas elaboradas nas páginas do jornal constituíram-se em suportes para memórias e para a construção da consciência histórica acerca do tempo presente vivenciado durante a transição entre a ditadura e a democracia.
La televisión ante el pasado reciente: ¿Cómo estudiar la relación entre TV y memoria social?
Authors: Feld Claudia
Published: April 2019

RESUMEN: Este artículo propone indagar las maneras en que la televisión representa el pasado reciente de la Argentina, a través de tres articulaciones específicas entre TV y memoria social. Se sugieren tres abordajes, distintos en términos analíticos, para la investigación. Estos abordajes permiten enfocar el rol de este medio en la configuración de agendas públicas (o sea, se aborda a la televisión como emprendedora de la memoria), su efectividad como soporte para difundir acontecimientos del pasado entre las nuevas generaciones (es decir, como vehículo de transmisión intergeneracional), o su rol como constructor de sentidos a través de imágenes, sonidos y palabras (es decir, la televisión se aborda como escenario de la memoria). Todos estos roles coexisten y se articulan, aunque también entran en tensión. El artículo se centra particularmente en la experiencia del terrorismo de Estado en Argentina, en el marco de la dictadura militar de 1976-1983, y en las memorias construidas en torno a la desaparición forzada de personas. El análisis de los vínculos entre TV y memoria permite pensar de qué modos los obstáculos para narrar una experiencia límite se combinan, de maneras complejas  y no fácilmente inteligibles, con la intención de vender un producto y de entretener al espectador. PALABRAS CLAVE: Televisión, memoria, imagen, dictadura, represiónAUTOR: Claudia FELD INSTITUCIÓN: CONICET – IDES RESUMEN EN INGLÉS TITLE: Television as regards the recent past. How to study the link between TV and social memory.ABSTRACT:This article aims to examine the ways in which television represents Argentina’s recent past, through three specific links between TV and social memory. Three approaches for research are proposed, which are different in analytical terms. These approaches allow us to focus on the role this medium plays in configuring public agendas (that is, television is approached as an entrepreneur of memory); its effectiveness as a medium which communicates past events to new generations (i.e., as a vehicle of transmission among generations); or its role as a constructor of meanings through images, sounds, and words (that is to say, television is approached as a stage for memory). All of these roles co-exist and are intertwined, but there  is also tension among them. This article especially focuses on the experience of state terrorism in Argentina, in the framework of the military dictatorship in 1976-1983, as well as on the constructed memories about the disappearance of persons. The analysis of the links between TV and memory allows us to think how the obstacles to narrate an extreme experience are combined, in complex and not easily intelligible ways, with the sale of a product and entertainment.KEYWORDS: Television, memory, image, dictatorship, repression
CROSBY, Alfred W. Imperialismo ecológico: a expansão biológica da Europa, 900-1900. Tradução José Augusto Ribeiro, Carlos Afonso Malferrari. São Paulo: Companhia da Letras, 2011
Authors: Vencatto Rudy Nick
Published: April 2019

A obra de Alfred W. Crosby, Imperialismo Ecologico: a expansão biológica da Europa, 900-1900 problematiza o processo de expansão das populações europeias principalmente por volta dos anos 900 a 1900. Mesmo sem perder de vista um recorte temporal mais longínquo, o foco de sua discussão concentra-se na invasão biológica lançada pelas levas europeias em outras regiões do planeta, as quais constituíram aquilo que denominou de “biota portátil”[i]. Para Crosby, fora a biota portátil a responsável por expulsar ou até mesmo eliminar a flora, fauna e os habitantes nativos de distintas regiões do mundo, dando origem às “Neoeuropas”: Austrália; Nova Zelândia e América. [i] Conjunto de animais, plantas e doenças que navegaram com os europeus  efetivando projetos de colonização e dominação de novas terras.
Os petistas e a crise do socialismo real: os desafios da renovação e as heranças das esquerdas tradicionais
Authors: Gomes da Costa Izabel Cristina
Published: April 2019

O artigo analisa alguns aspectos do debate petista sobre a crise do socialismo real. Investiga a incidência do colapso daquela experiência sobre as visões de socialismo no PT. O texto também aborda o diálogo e o confronto entre as heranças da II e da III Internacional e o socialismo petista – que fazia da ideia do “marco zero”, da construção de um “novo socialismo”, desapegado das tradições – a marca de nascença do seu projeto alternativo de sociedade.
El archivo como productor. El lugar del uso en El deseo nace del derrumbe, de Roberto Jacoby.
Authors: Garbatzky Irina Ruth
Published: April 2019

Resumen: Durante la primera década del 2000, varias experiencias artísticas, poéticas y políticas de las vanguardias argentinas del '60 y de ciertos movimientos contraculturales del proceso de recuperación democrática han sido objeto de numerosas investigaciones, muestras retrospectivas, archivos y documentales. La condición ciertamente expansiva de dicha serie nos trae la observación acerca de una puesta en peso de la noción de archivo: no sólo como reunión y domiciliación de un conjunto documental, sino como herramienta conceptual idónea para un pensamiento sobre las materialidades en las artes y en la literatura. En el presente artículo se aborda, a partir de una perspectiva foucaultiana del archivo (como sistematización y normativa de emergencia de los discursos), un entramado discursivo en torno al rol del archivo como productor no sólo de relatos críticos sobre la tarea de archivar sino, especialmente, como dispositivo de uso de bienes culturales comunes. Dicho dispositivo intervendría en la tensión vanguardia/musealización abriendo nuevos lugares de problematización de lo político. Para ello se rastrea en el volumen "El deseo nace del derrumbe. Acciones, conceptos y escritos", de Roberto Jacoby (Ana Longoni, compiladora) (2011), distintos momentos en los cuales la estrategia del uso se encontraba vinculada a su práctica artística.

DESEMPREGO METROPOLITANO NO BRASIL: 1999-2007
Authors: Bastos Raul Luís Assumpção
Published: April 2019

O artigo constitui-se em um estudo sobre o desemprego nas regiões metropolitanas de Belo Horizonte, Porto Alegre, Recife, Salvador e São Paulo e no Distrito Federal, no período 1999-2007. Inicialmente, analisa-se a evolução da taxa de desemprego total, por tipo e o tempo médio de permanência dos indivíduos na condição de desempregados. Posteriormente, aplica-se um método de decomposição para tratar das mudanças na participação de grupos populacionais e socioeconômicos no estoque de desempregados de cada uma das regiões. O estudo revela que houve redução da incidência do desemprego em todas as regiões desde 2004, o que se coadunou com uma melhora da performance macroeconômica do país a partir desse ano. Quanto às mudanças na composição do desemprego, ocorreu aumento da participação das mulheres, dos indivíduos adultos e dos mais escolarizados nos estoques de desempregados das regiões e redução da participação dos chefes de domicílio.
IMPACTS OF IMPORT TARIFF REMOVAL AND CHANGES IN INTERNATIONAL PRICES ON THE APPLICABILITY OF THE TRADITIONAL HOS TRADE THEORY
Authors: Bittencourt Mauricio Vaz Lobo
Published: April 2019

This paper examines the effects of agricultural and nonagricultural trade policy changes in the Brazilian economy using a computable general equilibrium model (CGE). An extended Salter-Swan model is employed to verify if the Stolper-Samuelson theorem (SST) holds after having a trade barrier removed and the consequences in terms of prices, production and resources allocation. Results show that the Stolper-Samuelson hypothesis is reversed when imports and domestic goods are poor substitutes. Reduction in import tariff increases national income, which implies that inappropriate trade policy adjustments can stand in the way of promoting rapid and equitable economic growth. Further, our results show that changes in relative factor prices in Brazil depend not only on changes in commodity prices, as in the SST, but also on changes in the balance of trade and factor endowments. This study mainly proposed to verify a specific result from a theoretical trade model, which makes important to stress the carefulness about the empirical results obtained to the Brazilian trade policies.
