Cultura, Educação e Informação: abordagem histórico-discursiva no contexto brasileiro
Authors: Marteleto Regina Maria 
Published: January 2021

O artigo trata da relação entre cultura, educação e informação no Brasil, recuperando alguns eixos discursivos sobre esses conceitos, formulados desde o final do século XIX e ao longo do século XX. Retoma discursos que relacionaram a cultura, no final do século XIX, à identidade nacional e ao nacional e popular. A partir dos anos 1920 as tentativas de descoberta do Brasil se orientaram para uma definição discursiva do caráter nacional brasileiro e por um projeto cultural amplo rumo à modernidade no país. Nos anos 1940 e 1950 os discursos referidos à modernização do país adquirem instrumental científico e feição pragmática com a aproximação das ideias de cultura e educação. No início dos anos 1960 elaboram-se contradiscursos nascidos dos movimentos culturais e educacionais para gerar conscientização e mobilização dos grupos populares. Com o golpe militar de 1964 e o regime autoritário que se seguiu, cultura e educação terão tratamentos políticos e técnicos diferenciados, formando esferas próprias e específicas sujeitas às políticas estatais. Ao mesmo tempo, era o momento da formulação de políticas de modernização econômica e da conformação de um mercado de bens culturais promovido pela indústria cultural que se implantava no país. Começava a se delinear uma cultura informacional de extensão mundializada.

NATURAL AND ARTEFACTUAL LANGUAGES
Authors: Distin Kate 
Published: January 2021

Abstract
Natural language provides a mechanism for cultural evolution by ensuring the persistent heredity of variations in both cultural information and information about its own construction. In the process, it not only facilitates but also limits our thinking to the ways its vocabulary and structures make possible. But the human capacity for metarepresentation frees cultural information from the restrictions of any one medium or language, and has also propelled the evolution of artefactual languages, which provide evolutionary mechanisms for specialist areas of culture. And cooperation between diverse cultural specialists can stimulate further, innovative competition between the cultural information that they share.

This study was conducted to evaluate the effectivenes and biological activity of Melia azedarach L. (Meliaceae) seed extract against armyworm, Spodoptera litura F. The first instar larvae were fed extract-treated cotton leaves for 2 days, then were maintained on untreated leaves until the third instar stage. Records were kept in regard to the larvae mortality and developmental time of surviving larvae from first instar to third instar. The result showed that Melia azedarach L. seed extract at consentration of 50 g of seeds/l of water (5%) exhibited moderate insecticidal activity against S. litura larvae (43.33 - 68.33% mortality). Addition of detergen at 0.2% to extract did not increase insecticidal activity of the extract. However, boiling seed extract at consentration of 50 g of seeds/l of water (5%) during 10 until 20 minutes increased insecticidal activity of extract (66.67 - 68.33% mortality). Generally, M. azedarach seed extract treatment did not affect developmental time of S. litura larvae.

Detection of Turnip mosaic virus in seed and leaf tissue. The study was conducted to test the seed transmission efficiency of Turnip mosaic virus (TuMV) on caisin (Brassica rapa) and the susceptibility of plant to the virus at different ages. Two detection techniques, ELISA and RT-PCR, were used to determine the more appropriate method for detection of TuMV. Two different sources of seeds involved those from farmer and commercial seeds were collected from West Java and Central Java. TuMV was inoculated on test plants at 2, 4, 6, 8, and 10 weeks after transplanting. Infected plants were confirmed using ELISA and RT-PCR techniques with specific antiserum and primer. TuMV was detected from farmer seeds originated from Ciherang and Cinangneng with percent infection of 15% and 2% , respectively. Plant growth and symptom development were affected by time of infection. In general, TuMV infection caused symptoms, mosaic, malformation, vein clearing, and blister on the leaf. The youngest plants were more susseptble and shown more severe symptoms. Absorbent value of ELISA from infected plants was in the range of 2.1 – 2.4. Spesific DNA band, 800 bp, was amplified from infected plants.

Transgene Identity and Number of Integration Sites and Their Correlation with Resistance To PStV in Transgenic Peanuts Carrying Peanut Stripe Virus (PStV) Coat Protein Gene. This research aimed to determine (1) the identity and copy number of PStV cp gene in transgenic peanut plants carrying PStV cp gene and (2) correlation between the identity and the number of integration sites and resistance to PStV infection. One T0 transgenic peanut was selfed up to five generations. T2, T3, and T5 plants were mechanically inoculated with PStV. Samples of T5 plants derived from several different T4 plants were subjected to Southern analysis to confirm the integration of PStV cp gene and to determine its identity and copy number. The Southern analysis showed three bands of different size, i.e. 1.1 kb, 1.3 kb, and 5.8 kb. Most of the lines of T5 generation have one insertion site, suggesting that the three insertion sites were located in different loci. Based on the phenotypic data, the transgenes of 1.1 kb and 1.3 kb were functional, resulting in resistant or recovery phenotype, while that of 5.8 kb was not functional. Copy number apparently had no effects on the phenotypes.

Resistance Evaluation of Chillipepper Cultivars for Cucumber Mosaic Virus and Chilli Veinal Mottle Virus. The use of resistance culivars is an important strategy for management of virus infection in chillipepper. A research was undergone to study the effect of single and mix infection of CMV and ChiVMV on the disease incidence and on the growth and yield of nine chillipepper cultivars, i.e. Cilibangi 4, Cilibangi 5, Cilibangi 6, Helem, Jatilaba, Tit Bulat, Tit Segitiga, Tit Super and Tampar. Mechanical inoculation was conducted to transmit the virus. Infection of the virus was then confirmed with DAS-ELISA. In general, inoculated chillipepper cultivars developed similar symptoms, i.e. mosaic type for CMV and mottle type for ChiVMV. More severe symptom was not always observed from mix infection of CMV and ChiVMV. Disease incidence occurred in the range of 16.67 – 86.0% and this caused 18.3 – 98.6% yield loss. Based on symptom expression, ELISA result, and reduction on yield, it can be concluded that all chillipepper cultivars used in this study could not hold up the virus infection. However, several cultivars showed tolerance response : Jatilaba, Tit Super, and Tampar for CMV; Cilibangi 4 for ChiVMV; Tit Super for mix infection; and Cilibangi 5 for CMV, ChiVMV, and mix infection. Further evaluation and investigation involving different chillipepper cultivars should be conducted.

Los objetivos de este estudio fueron por un lado, describir el rendimiento en una prueba de rendimiento cardiovascular realizada en laboratorio y en otra de esprints repetidos (RSA) en árbitros de fútbol de alto nivel, y por otro lado, analizar la asociación entre los resultados obtenidos en ambas pruebas. Doce árbitros de fútbol de alto nivel (Divisiones 1ª, 2ª y 2ª B, 28,8±5,1 años, 73,2±6,6 kg, 1,8±0,1 m 22,82±1,38 kg·m-2) participaron en el estudio. Los árbitros obtuvieron un consumo máximo de oxígeno (VO2max) de 59,50±4,56ml·kg-1·min-1. El tiempo medio de los esprints repetidos (RSAMedia) en 15 y 30 m fue de 2,54±0,09 s y 4,43±0,14 s, respectivamente, tardando 15,26±0,53 s y 26,60±0,82 s en completar los seis esprints (RSATotal). Los índices de fatiga en 15 y 30 m fueron de 2,25±1,05% y 3,33±1,59% (RSASdec) y de 3,45±2,92% y 6,31±4,63% (RSACambio).Se obtuvieron asociaciones positivas entre distintas variables cardiovasculares y de tiempo en RSA. Por el contrario, el consumo de oxígeno en las intensidades de umbral ventilarorio 1 (VT1) y umbral ventilatorio 2 (VT2) correlacionó negativamente con el índice de fatiga RSASdec.Una mayor capacidad cardiovascular en árbitros de fútbol, a pesar de poder producir un efecto negativo sobre el tiempo empleado en el RSA, puede minimizar la fatiga durante los esprints repetidos.
