Protestar por los derechos, el derecho a protestar. Una lectura desde las audiencias
Authors: Berti Silvina , Cantú Ariadna
Published: September 2020

Las protestas sociales, concebidas como acciones colectivas por las cuales se reivindican ciertos derechos, suelen encontrar su amplificación en los medios de comunicación, a cuyas reglas, sin embargo, deben someterse. Asimismo, en la recepción operan múltiples variables que cierran el sentido del discurso televisado. Este trabajo se enfoca en el momento del consumo de la protesta mediatizada, intenta identificar los significados que ella adquiere, particularmente en torno al complejo juego entre los derechos en jaque, los derechos mediatizados y las interpretaciones que de todo ello surge en la audiencia.

Authors: Quiroz Silvia S. , Dari Nora L. , Cervini Rubén A.
Published: September 2020

La importancia del efecto de la oportunidad de aprender (OdA) sobre los niveles de aprendizaje de los alumnos en los diferentes niveles del sistema educativo ha sido una de las líneas de investigación educativa más prolífera. En este estudio se investiga la relación entre la OdA y el rendimiento en Ciencia con base en los datos de pisa 2015 de Argentina, compuesta por 6.316 alumnos en 231 escuelas. Se consideran tres dimensiones de la OdA: la capacidad para comprender la tarea, la disposición del estudiante a participar activamente en el aprendizaje y la calidad de la instrucción. Las variables de control son los niveles socio-económico del alumno y de la escuela, y los recursos escolares disponibles. Todos los indicadores son construidos con base en los cuestionarios aplicados al alumno y al director del establecimiento. Los datos se analizan con modelos multinivel con dos niveles (alumno y escuela). A nivel escuela, los resultados indican que existe una importante segmentación institucional en la OdA y tal segmentación actúa casi exclusivamente como intermediaria del efecto de la segmentación socioeconómica y de recursos escolares del sistema educativo. A nivel alumno (intra-escuela), los indicadores de OdA muestran un efecto importante aun cuando estén ajustados por las variables de control.
ATTRIBUTES OF PROSPECTIVE PLANT GROWTH PROMOTING HALOPHILIC BACTERIA (PGPHB) SCREENED FROM SALINE SOILS OF BARAMATI TEHSIL OF MAHARASHTRA STATE (INDIA)
Authors: Mahamuni Shrikumar Vijaykumar
Published: September 2020

The important constraint for food production is soil salinity as it limits crop yield. In the present investigation, plant growth promoting halophilic bacteria (PGPHB) from saline soil of Baramati Tehsil of Maharashtra State were isolated, identified and characterized using physicochemical, biochemical, 16SrRNA gene sequencing and phylogenetic analysis. Plant growth promoting traits of two identified PGPHB were also detected. Isolates were moderate halophiles identified as Haererehalobacter sp. SM2 and Halomonas sp. SM3. They grew optimally within the range 3% to10% NaCl concentration. Both isolates were indol acetic acid producing, phoshate solubilizing and nitrogen fixing bacteria having big potential for bioremediation of salt affeced soils for crop production.

Published: September 2020

12  halophilic strains from different hypersaline environments such as solar salterns in Tuzlagözü (Sivas), Fadlum (Sivas), Kemah (Erzincan), a hypersaline spring water in Pülümür (Tunceli) and a saline lake in Delice (Kırıkkale) belonging to Turkey, were investigated in terms of levan production. After incubation and ethyl alcohol treatment, dialysis process was operated for partial purification.  Levan amounts in our samples after hydrolysis were calculated based on the amount of sugar obtained by acid hydrolysis of standard levan. Sugar amount of samples were determined using by high performance liquid chromatography system (HPLC). 1H-Nuclear Magnetic Resonance (1H-NMR) spectra of the levan sample and standard were recorded. The results obtained by HPLC analysis showed that Chromohalobacter canadensis strain 85B had highest production potential as 234.67 mg levan/g biomass.  The chemical shifts of 1H-NMR spectrum of the extracted levan also showed high similarity to those of pure levan isolated from Erwinia herbicola. Furthermore, Marinobacter sp. 163Y strain also is also capable with regard to levan production. In this study, this strain could yield 230.80 mg/g levan and this potential was first reported in the literature.
Endemic Non–SARS-CoV-2 Human Coronaviruses in a Community-Based Australian Birth Cohort
Authors: Grimwood Keith , Lambert Stephen B. , Ware Robert S.
Published: September 2020

BACKGROUND AND OBJECTIVES:

The coronavirus (CoV) disease 2019 pandemic has drawn attention to the CoV virus family. However, in community settings, there is limited information on these viruses in healthy children. We explored the epidemiology of the 4 endemic (non–severe acute respiratory syndrome CoV 2) human coronaviruses (HCoVs) by species, including acute illness episodes, risk factors, and health care burden in Australian children in the first 2 years of life.

METHODS:

The Observational Research in Childhood Infectious Diseases community-based cohort was a prospective study of acute respiratory illnesses in children from birth until their second birthday. Parents recorded daily symptoms, maintained an illness-burden diary, and collected weekly nasal swabs, which were tested for 17 respiratory viruses, including HCoVs, by real-time polymerase chain reaction assays.

RESULTS:

Overall, 158 children participating in Observational Research in Childhood Infectious Diseases provided 11 126 weekly swabs, of which 168 were HCoV-positive involving 130 incident episodes. HCoV-NL63 and HCoV-OC43 were most commonly detected, accounting for two-thirds of episodes. Whereas 30 children had different HCoVs detected on different occasions, 7 were reinfected with the same species. HCoV incidence in the first 2 years of life was 0.76 episodes per child-year (95% confidence interval [CI] 0.63 to 0.91), being greatest in the second year (1.06; 95% CI 0.84 to 1.33) and during winter (1.32; 95% CI 1.02 to 1.71). Fifty percent of HCoV episodes were symptomatic, and 24.2% led to health care contact.

CONCLUSIONS:

In children, HCoV infections are common, recurrent, and frequently asymptomatic. In future studies, researchers should determine transmission pathways and immune mechanisms.

Authors: Pereira Veronica Aparecida , Rodrigues Olga Maria Piazentin Rolim , Izidoro Isabela Rocha
Published: September 2020

O presente artigo buscou: 1) descrever e comparar: a) a qualidade do vínculo entre o bebê-mãe e  bebê-educadora, aos nove e doze meses de vida; b) a percepção do temperamento do bebê pelas mães e educadoras e, 2) correlacionar os indicadores de vinculação com os escores obtidos nas escalas de temperamento. Participaram nove bebês e suas respectivas mães e duas educadoras que responderam a escala de temperamento e foram filmadas individualmente com os respectivos bebês, aos nove e doze meses. Os resultados indicaram a presença de vinculação primária com a mãe e secundária com a educadora, ambas satisfatórias. Não houve correlações entre temperamento e comportamentos interativos na interação mãe-bebê, mas foram observadas entre educadora-bebê. Embora o vínculo mãe-bebê seja mais forte, a qualidade estabelecida com as educadoras sugere que a transição para a educação infantil pode ser positiva.

ABSTRACT Objective: to identify predictive factors for lethality and complications of deep fascial space infections of the neck (DFSIN), establishing an early and aggressive treatment in the neck before the progression to descending mediastinitis. Methods: we retrospectively analyzed 133 cases of DFSIN treated at Discipline of Head and Neck Surgery of the Medicine School of Santa Casa de Misericórdia de São Paulo. We accessed demographic characteristics, associated diseases, clinical presentation, laboratorial tests, length of hospital stay, number of involved anatomic neck spaces, intra-operative and microbiology findings. We analyzed these data using logistic regression to predict DFSIN lethality and life threatening complications (mediastinitis, septic shock, pneumonia, pleural empyema, skin necrosis). Results: lethality and complication ratios were 9% and 50.3%, respectively. The logistic regression model showed that patients with septic shock were more likely to have progression to death (p < 0.001) and, the presence of more than two involved neck spaces (p < 0.001) and older individuals (p = 0.017) were more likely to have complicated deep neck infections. Descending necrotizing mediatinitis increased the lethality ratio by 50%, and was associated to necrotizing fasciitis (p=0.012) and pleural empyema (p<0.001). Conclusion: septic shock is a lethal predictive factor and age as well as more than two involved neck spaces are the predictive factors for complications. Necrotizing fasciitis is an important factor for complications and death. Therefore, its surgical treatment must be more aggressive. Descending mediastinitis has a high lethal rate and the successful treatment is based on early diagnosis and aggressive surgical approach.

Published: September 2020

Resumen: La mortalidad evitable es un indicador clave para la toma de decisiones en salud pública, que considera las muertes que podrían haberse evitado mediante la prevención de enfermedades o la atención en los servicios de salud. En Colombia no se cuenta con un inventario específico que permita estimar la magnitud, distribución y evolución de la mortalidad evitable en la niñez. El objetivo fue proponer una lista de causas de muerte potencialmente evitables para niños menores de cinco años de Colombia. A partir de tres listas de mortalidad evitable para niños, se evaluaron 6.800 causas de defunción según su potencial evitabilidad en Colombia. Después de analizar la plausibilidad -etiológica y de acuerdo con la historia natural de la enfermedad- se descartaron 595 eventos; posteriormente, se ingresaron a la lista las causas coincidentes en al menos dos inventarios de referencia. Para aquellas contenidas en un solo inventario (1.751) se aplicó el método Delphi convencional con dos etapas para valorar el consenso entre expertos. Todas las causas resultantes fueron asignadas a un grupo de evitabilidad y validadas en dos ocasiones. En cada ronda se calculó el porcentaje de acuerdo global y kappa de Fleiss para múltiples evaluadores. En total, fueron identificadas 6.168 causas de defunción potencialmente evitables en niños menores de cinco años, categorizadas como tratables (39,5%), prevenibles (47,4%) o mixtas (13,1%). Se encontró consenso entre los expertos en salud infantil en cuanto a la potencial evitabilidad. El conjunto final es satisfactorio. Se recomienda su utilización en el contexto colombiano.

Published: September 2020

Abstract The aim of this study was to evaluate the effect of 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide (EDC) on bond strength of fiberglass posts in root canals obturated with different endodontic sealers. Seventy-eight mandibular premolars were obturated with three sealers (n=26): Endofill (END), AH Plus (AHP), and Endosequence BC Sealer (EBS). After preparation of the post space, two subgroups were formed according to the cementation of the posts (n=13): with EDC (EDC), and without EDC (control - CON). The specimens were submitted to a pull-out test, failure mode classification, and root canal surface evaluation by scanning electron microscopy after post displacement. Regarding the bond strength, a significant difference between the EDC and CON subgroups occurred only in the END (p=0.001). No difference was detected among the CON subgroups (p=0.339). However, among the EDC subgroups, AHP presented significantly higher values (END versus AHP: p=0.001; AHP versus EBS: p=0.016). Upon classification of failure modes, score 1 (≥ 50% of cement) was the most commonly observed, except for the END + EDC. Remains of endodontic sealers and resin cements were found in the cervical third, but without statistical difference (p=0.269), while in the middle third, difference occurred (p=0.004). In conclusion, EDC decreases bond strength when associated with END sealer, without changing the failure mode between the resin cement and fiberglass post. The best performance was observed when EDC was combined with AHP sealer.

Published: September 2020

Abstract The aim of this study was to clinically and radiographically compare extra short and standards implants. Forty-two implants were installed in 10 selected patients. They received prosthetic loading only after the conventional waiting time for osseointegration and the prostheses were made ferulized. Radiographic shots were performed to evaluate vertical and horizontal bone losses at times T1 (prosthetic installation), T2 (6 months follow-up) and T3 (12 months follow-up). Biological parameters such as bone level around the implants (CBL) were evaluated, CBL alteration (CBLC), total crown length (TCL) and implant/crown ratio (ICR) were digitally calculated. All implants included in the study were submitted to the analysis of the implant stability quotient (ISQ) at the time of implant installation (T0) and at 12 months of prosthetic function (T3). Data were statistically tested. The ICR was higher in the test group than in the control group (p<0.0001). The CBL measurements at the beginning of the study were 0.21±0.19 mm and 0.32±0.38 mm and at 12 months 0.65±0.24 mm and 0.87±0.34 mm, respectively in the test and control groups. CBLCs and CBL were similar at all times (p>0.05). No correlation was found between CBLC and ICR parameters, as well as between ISQ and implant length. We may conclude that standards and extra short implants can provide similar clinical results in prosthetic rehabilitation of the atrophic jaw over 12 months of follow-up.

Authors: Shafiei Fereshteh , Memarpour Mahtab , Jowkar Zahra
Published: September 2020

Abstract This study was conducted to evaluate whether antibacterial pretreatment irrigation with silver nanoparticles (SNPs) and silver diamine fluoride (SDF) has any effect on bond strength of fiber posts cemented with three types of resin cements in root canal space. Fifty-four endodontically treated maxillary central incisor roots were prepared for fiber post (FRC Postec Plus NO.3, Ivoclar Vivadent) cementation and divided into nine groups in terms of three cement types and two pretreatments with silver antibacterial agents. The cements were as follows: an etch-and-rinse cement (ER, Excite DSC/Variolink N), a self-etch cement (SE, ED Primer/Panavia F2.0), and a self-adhesive cement (SA, Panavia SA Luting Plus). For each cement, the control group was with no treatment and two experimental groups were with SNPs and SDF treatments that were used after acid-etching for ER cement and after EDTA treatment for SE and SA cements. After fiber post cementation, each bonded root was horizontally sectioned into 1-mm thickness microslices to create two slices for each root region (apical, middle and coronal) and underwent push-out bond strength (PBS) test. Data in MPa were analyzed with two-way ANOVA and Tukey test (p=0.05). The interaction of the pretreatment type and cement type was significant (p<0.001). SNPs and SDF significantly increased PBS with ER cement (p≤0.04). This positive effect was also marginally significant for SDF with SE cement (p=0.049). For SA cement, SNPs showed a significant positive effect, but SDF had a significant adverse effect on PBS (p<0.001). The effect of pretreatment with silver antibacterial agents prior to adhesive cementation of fiber posts depends on the resin cement used. Contrary to SNPs with beneficial or no significant effect on bonding for all cements, SDF exhibited a deleterious effect with self-adhesive cement.
ALGUNAS REFLEXIONES SOBRE DILEMAS ÉTICOS DEL CUIDADO EN UN ENTORNO DE PANDEMIA
Authors: Perea Juan Guillermo Figueroa
Published: September 2020

Resumen En este texto se propone un esquema para analizar dilemas éticos en el contexto de la pandemia del Covid 19, los cuales se presentan ante un conflicto moral al que se enfrenta una persona (por criterios normativos en tensión) o, cuando varias personas o instancias normativas tienen distintas estrategias ante un evento específico y, además, cada quien asume que su postura es la más aceptable. La ética no decide cuál es la referencia moral correcta, sino que analiza los supuestos de distintas normatividades y acompaña a tomar conciencia de los mismos. El texto no propone soluciones, sino que presenta un esquema de análisis ético, que considera como insumo clave la identificación de actores relacionados con el contexto de la pandemia y la forma en que son tomados en cuenta. Se recupera la categoría de cuidado, como recomendación central para lidiar con la pandemia y como supuesto de todo análisis ético.
“FIQUE EM CASA”: A GESTÃO DE RISCOS EM CONTEXTOS DE INCERTEZA
Authors: Spink Mary Jane Paris
Published: September 2020

Resumo Partindo do pressuposto de que há lacunas no conhecimento sobre o novo coronavírus, este ensaio versa sobre a gestão de riscos em situações de incerteza. Inicia-se situando a pandemia de SARS CoV-2 e as características que nos levam a afirmar que há zonas de incertezas a ele associadas. A seguir, introduz-se a noção de gerenciamento de riscos como preâmbulo para uma breve síntese das medidas governamentais adotadas para controle da epidemia. Nesse enquadre é problematizada a “dança das palavras,” focalizando as estratégias de distanciamento social, discussão que leva à comunicação sobre risco e suas implicações para a adesão às medidas de distanciamento social no enquadre das teorizações sobre percepção de risco. Conclui-se, propondo que a contribuição da Psicologia Social, nessas situações, requer duas habilidades: de um lado, a comunicação sobre riscos e, de outro, entender como essas informações são processadas e significadas em distintos segmentos sociais.

Authors: Moreira Lisandra Espíndula , Alves Júlia Somberg , Oliveira Renata Ghisleni de , Natividade Cláudia
Published: September 2020

Resumo Nesse ensaio, objetivamos pensar a pandemia a partir da situação das mulheres. Para tanto, analisamos o modo como a crise sanitária aciona teórico-politicamente noções sobre a casa e a guerra, tomadas como dispositivos de análise. A casa tenciona fronteiras entre público e privado, principalmente ao olharmos para a violência contra mulheres e para o trabalho doméstico. A guerra, estratégia que tem sido usada para pensar o combate ao coronavírus, aciona masculinidades afastando as mulheres dos espaços de decisões políticas para enfrentamento da pandemia, apesar de estarem na linha de frente como trabalhadoras da saúde e em outros serviços essenciais. Entretanto, a gramática bélica também possibilita a denúncia de ataques às mulheres em tempos de crise. Nos usos destes dispositivos, identificamos modos de direcionar a comoção social e hierarquizar vidas. Atentamos para a importância de transversalizar a perspectiva de gênero na construção de políticas públicas durante e pós-pandemia.
O PARADOXO DO ISOLAMENTO NA PANDEMIA SEGUNDO O POVO INDÍGENA SATERÉ-MAWÉ/AM
Authors: Sawaia Bader Burihan , Albuquerque Renan , Busarello Flávia Roberta
Published: September 2020

Resumo O artigo teve como meta analisar e aprofundar interpretações acerca da relação entre desigualdade e pandemia em dimensão psicossocial, com foco no isolamento enquanto questão emblemática para indígenas Sateré-Mawé, do Amazonas, e nos afetos como categoria analítica. Buscamos referencial teórico em Spinoza e Vigotski para a concepção ético-política dos afetos. Inferências descritas tiveram base em documentos públicos e etnografia continuada. Observamos afetos vivenciados diante de uma situação de isolamento territorial dos étnicos da TI Andirá-Marau, que remetem ao paradoxo dessa estratégia recomendada aos povos indígenas. Concluímos que a pandemia, para sociedades nativas, tem ativado medos históricos, situados a partir de violências do passado, mas também fomentou sabedorias salvadoras de vida.
METÁFORAS DE UM VÍRUS: REFLEXÕES SOBRE A SUBJETIVAÇÃO PANDÊMICA
Authors: Carvalho Mario , Luz Anna Clara da Rocha , Paulino Bruna Rossigneux , Ferreira Camilla Cristine Ignacio
Published: September 2020

Resumo O presente artigo visa explorar diferentes metáforas acionadas na primeira fase da pandemia do novo coronavírus no Brasil, inspirado na obra de Susan Sontag, A doença como metáfora. As metáforas são ferramentas centrais nos processos de subjetivação da pandemia, do vírus que a causa e da doença que ela materializa. O material empírico que sustenta nossas reflexões vem de encontros semanais de um grupo terapêutico que passamos a conduzir on-line com as medidas de isolamento social no país, e de observação participante nas redes sociais da internet. Com base nisso, pensamos em quatro chaves de metáforas: o (in)visível, o mascarado, o divino e o isolado. A partir dessas categorias, é possível refletir sobre questões como sofrimento ético-político, resistência subjetiva, luto, negação, melancolia e megalomania, presentes nos modos de subjetivação da pandemia.

Published: September 2020

Resumo Este artigo tem como proposição discorrer acerca do acolhimento psicológico enquanto uma prática política de afirmação da vida e da saúde no panorama nacional, onde as políticas públicas para tratar a pandemia de Covid-19 tomam rumos distanciados de uma noção mais ampla de cuidado. Inspiradas na vivência de atuar em um dispositivo de acolhimento de uma universidade pública nesse momento de pandemia, nosso objetivo neste texto consiste em discutir os desafios para ultrapassar um modelo clássico de “acolhimento” em psicologia. Fundamentadas na cartografia, percorremos 05 pistas: “a-pandemia-em-nós”, “o acolhimento e seus rastros”, “contato, contágio e a potência dos encontros”, “o cuidado como revolução numa experiência viva de afirmação da vida” e “amparo e afeto numa prática engajada”. Tais pistas problematizam a prática do acolhimento psicológico partindo da reconfiguração das fronteiras relacionais em situações extremas, no caso, a pandemia, bem como das afetações que esse intervir produz nesse campo de atuação.

ABSTRACT Rosewood, Aniba rosaeodora is an endangered species in Amazon forests and its natural stands have been heavily depleted due to over-exploitation for the cosmetic industry. This study aimed to investigate the genetic diversity and population structure of 90 rosewood accessions from eight localities in the Peruvian Amazon through 11 Inter Simple Sequence Repeats (ISSR) primers. The ISSR primers produced a sum of 378 bands, of which 375 (99.2%) were polymorphic, with an average polymorphism information content (PIC) value of 0.774. The mean effective number of alleles (Ne), Shannon informative index (I), gene diversity (He) and total gene diversity (Ht) were 1.485, 0.294, 0.453 and 0.252, respectively. Analysis of molecular variance (AMOVA) showed the presence of maximum variability within populations (88%). The Structure algorithm, neighbor joining and principal coordinate analysis (PCoA) grouped the 90 rosewood accessions into three main populations (A, B and C). Diversity indices at the inter-population level revealed a greater genetic diversity in population A, due to higher gene flow. The neighbor-joining analysis grouped populations A and B, while population C was found to be divergent at the inter population level. We concluded that population A reflects higher genetic diversity and should be prioritized for future management and conservation plans.

Published: September 2020

ABSTRACT The ruderal babassu palm (Attalea speciosa) is expanding on large areas of degraded Amazon landscapes. Decomposition of leaves and roots is in the center of plant:soil interactions. We evaluated decomposition and nutrient concentrations of leaves and fine roots of babassu in comparison with two exotic reference species, Acacia mangium (slow degradability) and Leucaena leucocephala (fast degradability), in a 138-day litterbag assay carried out in secondary forest stands of different age and babassu abundance. We chose 4-mm over 2-mm mesh litterbags based on a pilot study. Babassu leaves degraded slower than leaves of A. mangium and L. leucocephala, and also had lower nitrogen, phosphorus and calcium concentrations in all stages of decomposition. By contrast, potassium concentrations in babassu leaves were higher than in both reference species at 0 and 50 days. Roots of all three species decomposed slower than leaves. Compared to the leaves, both biomass loss and nutrient concentrations differed less between babassu and reference-species roots, except for lower nitrogen concentration in babassu roots. Leaf-litter decomposition of all three species was significantly faster in old than in young secondary forest, suggesting an acceleration of decomposition along succession. Babassu leaves decomposed faster in old babassu-dominated than non-dominated secondary forest, pointing to the existence of specialized decomposer communities in babassu-dominated stands.

Published: September 2020

ABSTRACT Obtaining juvenile material may favor the clonal propagation of Brazil nut, Bertholletia excelsa. We aimed to assess the emission of epicormic shoots on detached branches of Brazil nut trees as a function of the mother tree and branch diameter, in order to provide juvenile material for use in clonal multiplication. The experimental design was completely randomized in a 6 (mother trees) x 3 (stem diameter: < 20 20-40 and 40-80 mm) factorial design, with four replicates. Every five days the number of shoots emitted was counted and the sprouting speed index and average sprouting time were calculated. The number of epicormic shoots and the sprouting speed index were dependent on the interaction between mother tree and branch diameter. Branches with larger diameter (20-40 and 40-80 mm) showed higher potential for obtaining propagules for use in Brazil nut clonal multiplication (cutting, grafting and in vitro cultivation).

Published: September 2020

ABSTRACT The increasing urbanization of the Amazonian biome has promoted the creation of several forest fragments surrounded by an urban matrix, but the relationship of animal assemblages to the urban environment, especially in forest fragments, is poorly known. Here we aimed to 1) determine the composition of the squamate fauna of the largest urban forest fragment from central Amazonia, in the Brazilian city of Manaus, and 2) evaluate the influence of environmental parameters on assemblage diversity. We sampled 10 standardized riparian plots through visual search in six surveys between 2008/09 and 2015, totaling 360 observer-hours. We found 15 species of lacertoids (lizards and amphisbaenians) and seven species of snakes through active search. After considering occasional encounters and search in museum collections, we recorded a total of 24 lacertoid and 22 snake species. Multiple regression models indicated that species richness and abundance of individuals increased with the distance from the edge of the fragment, while other structural parameters of the environment did not affect the assemblage. We conclude that this forest fragment 1) consists of a subset of the regional species pool, and 2) undergoes reduction of species richness and abundance of individuals from the center to the borders. This and additional urban forest fragments should be continually monitored in order to evaluate their long-term role in maintaining the tropical biodiversity.

ABSTRACT We assessed the effect of stocking density on physiological parameters (blood lactate, glucose, cortisol, hematocrit), water quality (temperature, dissolved oxygen, pH, unionized ammonia, carbon dioxide), and survival during the transportation of fingerling (24.5 ± 4.7 g) and juvenile (615.8 ± 122.2 g) pirarucu (Arapaima gigas) for six hours in plastic bags. The tested densities were 65, 80, 95, 110 and 125 g L-1 for fingerlings, and 50, 80, 110, 140 and 170 g L-1 for juveniles (three replicates each). Parameters were measured prior to and immediately after transportation, and at 24 and 96 hours recovery after transportation. No mortality was observed, except for fingerlings (< 3%) at densities of 110 and 125 g L-1 during recovery. All the water quality parameters were significantly altered after the transportation of fingerlings and juveniles. Water temperature, dissolved oxygen, carbon dioxide and unionized ammonia increased, but pH decreased. Only carbon dioxide and unionized ammonia differed among densities. Cortisol levels did not increase over time, except for the juveniles at 170 g L-1, which still had high cortisol after 96 hours. Glucose significantly increased after transportation for all the treatments and returned to the initial values during the recovery period. Conversely, the lactate values were still high after 96 hours. Hematocrit was assessed only for juveniles and was significantly lower after transportation. We conclude that fingerling and juvenile pirarucu can be safely transported at densities up to 95 g L-1 and 140 g L-1, respectively.

ABSTRACT Frugivores and zoocoric trees represent an important proportion of tropical rainforest biodiversity. As niche differences favor species coexistence, we aimed to evaluate morphological and temporal niche segregation mechanisms among zoochoric trees and canopy frugivores in a tropical rainforest in the northeastern extreme of the Brazilian Amazon. We tested the effects of fruit morphology, tree size, frugivore body size and time of day on fruit consumption. We recorded the frugivore species that fed on 72 trees (44 species, 22 genera) and whether these frugivores swallowed the seeds. We monitored trees only once from 07:00 to 17:00 h between January and September 2017. We observed fruit consumption in 20 of the 72 trees. Seventy-three frugivore individuals from 22 species visited the trees. Heavier fruits were consumed by larger frugivores, while seed size was inversely correlated with frugivore size. Narrower fruits and fruits with smaller seeds had greater probability of having their seeds ingested, and larger frugivores were more prone to ingest seeds. Trees bearing fruits with smaller seeds were visited by a greater number of frugivores. Taxonomic groups differed in the time of arrival at fruiting trees. None of the evaluated variables (fruit weight and size, and seed size) affected the richness of frugivores that visited the trees. We concluded that, in the studied forest, fruit morphology (weight, size and seed size) is a niche segregation mechanism among zoochoric trees, while body size and time of day are niche segregation mechanisms among frugivores.
Distribution update, conservation status and color in life of the rare Amazonian snake, Eutrachelophis papilio Zaher and Prudente 2019 (Serpentes: Xenodontini)
Authors: CITELI Nathalie , DE-CARVALHO Mariana , BRANDÃO Reuber
Published: September 2020

ABSTRACT The rare Amazonian snake Eutrachelophis papilio is known from only five individuals, from four localities, belonging to its type-series, the more recent collected over 10 years ago. Here, we expand its distribution and describe its color in life for the first time. We also provide an estimate of its distribution area using the minimum convex polygon method and identify the values of anthropic pressure within its known distribution range with the Human Footprint Index. The new occurrence is located 291 km from the nearest known locality and its distribution is associated with pristine forests. Considering its rarity, and the absence of demographic and biological data, we suggest that the species should be classified as Data Deficient by IUCN criteria.
Discursos diplomáticos: objeto de pesquisa da Comunicação Política?1
Authors: Pimentel Pedro Chapaval , Panke Luciana
Published: September 2020

Resumo O discurso diplomático, com suas narrativas estratégicas, possui características que envolvem persuasão, dissimulação e convencimento. Neste sentido, é um dos elementos que colaboram com a formação da imagem pública das nações, posicionando-as no contexto mundial. Partindo deste enfoque, nos perguntamos acerca da ênfase dada pelo campo da Comunicação à análise dos discursos diplomáticos enquanto Comunicação Política. Para isso, mapeamos sete bancos de dados nacionais e internacionais. Como resultados, destacamos que, dadas as disputas de poder imbrincadas nas relações internacionais, os discursos diplomáticos emergem como parte de um processo estratégico de comunicação internacional mais amplo por parte de Estados e governos. Embora consideremos esses discursos um objeto de Comunicação Política, constatamos a existência de uma escassa literatura sobre o tema na área de Comunicação e apresentamos sugestões para futuras pesquisas.
Cuando amar en África lo pagas con la vida
Authors: García-Oliveros Elena
Published: September 2020

Resumen El caso real de Marianna, lesbiana de origen senegalés, demandante de asilo en la ciudad de Bruselas, Bélgica, es la clave de este artículo que gira en torno a los modelos de persecución específicos de las mujeres homosexuales y las causas de su invisibilidad. El estudio se detiene específicamente en la mutilación genital femenina infligida con el agravante de lesbofobia y en el análisis de la simbología patriarcal que esta práctica conlleva y que conduce a su perpetuación hoy en día. Igualmente se exploran los datos acerca de la falta de sistematización en la denuncia de esta forma de proceder como modo de control del lesbianismo y las consecuencias que esta impunidad conllevan sobre las mujeres que huyen de sus países de origen buscando refugio. La investigación se enmarca dentro del proyecto de Arte Comunitario Cuando Amar en África lo pagas con la vida (2011) creado por Toxic Lesbian.
Del trabajo sexual al refugio: historia de vida de una mujer salvadoreña trans activista
Authors: Arévalo Amaral
Published: September 2020

Resumen Este texto analiza la relación de las Maras, el desplazamiento forzado y el refugio de personas salvadoreñas lesbianas, gay, bisexuales, personas trans, intersexuales y otras identidades sexuales y de género (LGBTI+) por medio del caso ilustrativo de Karla Avelar. Cuando se conjuntan las acciones de las Maras como la extorsión, la amenaza, la persecución o el asesinato, esto se transforma en el detonante para ejercer una movilidad forzada como vía de escape y huida intempestiva del país. El refugio se transforma en, muchos casos, la única oportunidad de sobrevivir para personas salvadoreñas LGBTI+ que huyen del asedio de las Maras.

Authors: Spiess Maiko Rafael , Mattedi Marcos Antonio
Published: September 2020

Resumo O artigo aborda o tema dos eventos científicos. Argumenta que os eventos científicos constituem uma estratégia de comunicação que afeta a comunidade científica de forma social, espacial e cognitiva. O texto operacionaliza conceitos e teorias sociológicas como forma de analisar os eventos científicos. Para isso, baseia-se em pesquisa bibliográfica e histórica. Está dividido em cinco partes principais: i. uma introdução com a problematização sociológica dos eventos científicos; ii. uma análise do processo de formação e desenvolvimento dos eventos científicos; iii. uma revisão crítica da abordagem sociológica do Programa Normativo de análise da atividade científica; iv. uma revisão do Programa Discursivo dos eventos científicos; v. uma conclusão, que oferece subsídios para desenvolvimento da abordagem sociológica dos eventos científicos. O artigo conclui que os eventos científicos podem ser vistos como espaços que refletem a estratificação da comunidade científica, mas também como arenas de persuasão que são mobilizadas no processo de construção do conhecimento.
Para além do Estado: Marx, Lenin e a crítica da estatalidade
Authors: Silva Rafael Afonso da
Published: September 2020

Resumo A leitura da crítica marxiana da estatalidade tem sido conduzida, em parte da literatura especializada, sob o pressuposto de uma dupla identidade: da própria obra marxiana e da tradição do pensamento marxista. Contrapondo-se a essa grade de leitura e identificando em Lenin o seu iniciador, o artigo explora as diferenças entre as críticas marxiana e leniniana da estatalidade, argumentando que essas diferenças derivam fundamentalmente do modo como se articulam a crítica do Estado e a problematização das formas econômicas de cooperação do capital. Na conclusão, destaca-se a importância da abordagem marxiana, que, no contexto defensivo da resistência à “pilhagem” do público-estatal, nos convida a analisar os regimes de práticas que estruturam as formas privada e pública de produção ou regulação de “bens” e “serviços” e a produzir tecnologias de “autotrabalho” e “autogoverno” na multiplicação de formas associativas orientadas para a “reabsorção” dos poderes subsumidos pelos dispositivos econômicos e políticos do capital.

Abstract: The objective of this work was to evaluate the effect of the use of different nitrogen fertilizers on N losses by NH3 volatilization and on the grain yield of a corn (Zea mays) crop grown in the semiarid region of the state of Sergipe, Brazil. Corn was managed under rainfed conditions and conventional tillage. The fertilization treatments were: sulfur-coated urea (SU) and organo-mineral-coated urea (OMU). Regular urea and ammonium sulfate (AS) were also included as a reference of N sources of high and low NH3-volatilization potential, as well as a control without N fertilization. The N sources were applied to the soil surface at a rate of 150 kg ha-1 N as side-dressing at the V5 growth stage of corn. The experiment was carried out in 2015 and repeated in 2016. Losses of N through NH3 volatilization differed among the N sources in the two study years, with AS presenting the lowest N losses and regular urea, the highest. In the area treated with OMU, losses by NH3 volatilization were consistently controlled, showing a reduction of 74 and 67% in relation to that of regular urea in both years. SU, however, only mitigated NH3-N losses in 2015, increasing them in 2016, compared with regular urea. Corn plant grain yield and N status, assessed by the index leaf, did not clearly reflect N losses by NH3 volatilization. For the semiarid of Sergipe, OMU is the best urea-based fertilizer to mitigate N losses by NH3 volatilization, and the use of AS is an alternative to increase corn yield and eliminate N losses as NH3.

Abstract: The objective of this work was to evaluate the variability present in two pea (Pisum sativum) F2 populations and their corresponding F2:3 families, as well as to determine, in both generations, the frequency of transgressive segregants in order to isolate early superior families. The study was conducted from a cross of green pea varieties (Ilca 5115 and Turf) and a cross of yellow pea varieties (Zavalla 15 and Amarilla). In both generations, morphological traits were evaluated. Phenotypic and genotypic variances, experimental error variance, genotypic and phenotypic coefficients of variation, broad-sense heritability, and transgressive segregants were determined. The green F2 population showed greater variation, whereas the yellow F2:3 families had higher average values for most traits. In the green F2:3 population, the percentage of transgressive segregants was greater or equal to 20, while, in the yellow one, no traits had a percentage greater than 20. High heritability values were obtained for most traits in both generations. Considering all traits, 45% of the transgressive segregants are found in the F2 populations and 42% of the F2 transgressive segregants in the F2:3 generation. The distribution of F2:3 families allows to select promising families according to the breeding program objectives.
