Authors: Reza Md. Selim , Habib Md. Ahasan , Mehedi Ibrahim Mustafa , Alam Md. Mottahir , Latif Shaikh Abdul
Published: June 2020

In the current study, a novel Zeonex based porous core photonic crystal fiber (PC-PCF) is presented for polarization-maintaining and dispersion flattened in the terahertz (THz) region. For minimizing the Effective Material Loss (EML), an array of three rectangular and six triangular air holes are surrounded by hexagonal-shaped cladding. Finite Element Method (FEM) is employed through Comsol V5.3a software to design and examine the essential features of the proposed porous core fiber which revealed that it has an extremely small EML of 0.04 cm−1 at 1.2 THz and has almost zero flattened dispersion of 0.8 ± 0.08 ps/THz/cm in 1.0–1.4 THz frequency spectrum. Moreover, the optimum designing parameters offer an extremely high value of birefringence (0.043 at 1.2 THz). Besides, other major features notably bending loss, effective area, and confinement loss are also found to be precise and relatively low. For effective, adaptable and fitting transmission characteristics, this type of design would lay the foundations for broadband THz radiation wide variety of usage in the THz regime.

The crystal structures of the salts [Li(1,2-F2C6H4)] [B(C6F5)4] (1) and Cs[B(C6F5)4] (2) comprise six Li···F contacts (1.965(3) − 2.312(3) Å) and twelve Cs···F contacts (3.0312(1) − 3.7397(2) Å), respectively, which are significantly shorter than the sum of van der Waals radii (3.29 and 4.90 Å).
Ownership Structure and Earnings Management: Empirical Evidence from Vietnam Real Estate Sector
Authors: Nguyen Anh Huu , Nguyen Linh Ha , Doan Duong Thuy
Published: June 2020

The young real estate market in Vietnam, an emerging country in Asia, has been growing remarkably. This is an attractive channel for investors, but it seems to be an unstable market and have high potential source of earnings management while investing in real estate companies listed in Vietnamese stock market. The research has been conducted to investigate the impact of the ownership structure on the earnings management of Vietnamese listed real estate companies. The research methodology includes four statistical approaches OLS, FEM, REM and REM (robust) that are employed to address econometric issues and to improve the accuracy of the regression coefficients. The research sample consists of 180 firm-year observations for 36 real estate companies listed on Vietnamese stock market over a period of five years, i.e. from 2014 to 2018. The results show that, while state ownership showed a positive influence, managerial ownership played negative significant roles in relation to earnings management. This research has implications for designing a better ownership structure in the Vietnamese real estate sector and enhancing information quality to protect investors.
Analytical Method for Correction Coefficient Determination for Applying Comparative Method for Real Estate Valuation
Authors: Gružauskas Valentas , Kriščiūnas Andrius , Čalnerytė Dalia , Navickas Valentinas
Published: June 2020

Real estate valuation uses 3 main approaches: income, cost and comparative. When applying the comparative method, correction coefficients based on similar real estate transactions are determined. In practice, the coefficients and similar real estate objects are usually determined by using qualitative approach based on the valuators’ experience. The paper provides an analytical method for the determination of correction coefficient, which limits subjectivity when using the comparative method for valuation. The provided analytical approach also integrates macroeconomic indicators in the calculation process. It also addresses issues when available historical real estate transaction data is limited. A machine learning approach was applied to determine the average price of real estate in the region, with the possibility of using this information to obtain correction coefficients where historical data was unavailable. Alternative research usually focuses on final price estimation of the selected real estate object; however, the valuation standard of Tegova released in 2018 does not allow for applying analytically based approaches for individual real estate object evaluation; these approaches can be used only as a supportive tool for valuators.
Legal-Surveying Documentation in the Registration of Rights to Properties of the Treasury and of Territorial Self-government Units – Case Study of Poland
Authors: Sobolewska-Mikulska Katarzyna , Cienciała Agnieszka
Published: June 2020

The Act of 21 August 1997 on Real Estate Management imposes on district governors within the management of the Treasury-owned real estates, as well as the commune head, the mayor or city mayor – in the case of the real estate resources of the commune, poviat management - to the poviat real estate resource and voivodship board, in relation to the provincial real estate resource – the obligation to undertake actions in court proceedings, particularly in cases concerning ownership or other property rights. In addition, it obliges them to submit applications for the establishment of a land register and for its updating.

In practice, there are numerous cases of negligence in the registration of such properties, in the updating of their designation and demonstration of rights that affect the legal status. For the purpose of this publication, examples of legal-surveying documentation were analyzed to indicate the most common problems encountered in Poland in the regulation process of the legal status of properties, and the typical content of maps for legal purposes was systematized. In addition, selected approaches used in the area of the registration of rights to properties in other countries of the world were indicated.
Editorial Foreword: Applying Existential Social Psychology to Mental Health
Authors: Vail Kenneth E. , Sullivan Daniel , Landau Mark J. , Greenberg Jeff
Published: June 2020

Human existence is characterized by some rather unique psychological challenges. Because people can reflect on their lives and place in the world, they are regularly confronted with a variety of existential concerns: death and mortality; the burdens of freedom; uncertainty regarding one's identity; isolation from others; and indeterminate meaning in life. Existential social psychology (Greenberg, Koole, & Pyszczynski, 2004; Vail & Routledge, 2020) investigates whether and how such existential concerns shape everyday life and, as highlighted in the present special issue, how such processes impact mental health and social functioning.
Perceived Tension, Movement, and Pleasantness in Harmonic Musical Intervals and Noises
Authors: Costa Marco , Nese Mattia
Published: June 2020

Perceived valence, tension, and movement of harmonic musical intervals (from the unison to the octave presented in a low- and high-register) and standard noises (brown, pink, white, blue, purple) were assessed in two studies that differed in the crossmodal procedure by which tension and movement were rated: proprioceptive device or visual analog scale. Valence was evaluated in both studies with the visual analog scale. In a preliminary study, the proprioceptive device was calibrated with a psychophysical procedure. Roughness of the stimuli was included as covariate. Tension was perceived higher in dissonant intervals and in intervals presented in the high register. The higher the high-pitch energy content in the standard noise, the higher the perceived tension. The visual analog scale resulted in higher tension ratings than the proprioceptive device. Perception of movement was higher in dissonant intervals, in intervals in the high register, and in standard noises than in musical intervals. High-pitch spectrum noises were associated with more sense of movement than low-pitch spectrum noises. Consonant intervals and low-register intervals were evaluated as more pleasant than dissonant and high-register intervals. High-pitch spectrum purple and blue noises were evaluated as more unpleasant than low-pitch spectrum noises.

Authors: Machado Vanessa , Lopes Joana , Patrão Mariana , Botelho João , Proença Luís , Mendes José João
Published: June 2020

Hormones and inflammatory mechanisms are implicated with female reproductive function, including follicle maturation, ovulation, embryo implantation, and pregnancy. Periodontitis is a chronic inflammatory disease due to a polymicrobial disruption of the homeostasis and may be considered as a potential risk factor that affect female fertility. The role of periodontitis is becoming meaningful, with significant associations with polycystic ovary syndrome, endometriosis and bacterial vaginosis. Further, periodontitis is linked with known risk factors towards female infertility, such as age, obesity, and chronic kidney disease. This review aims to summarize the available evidence on the association between periodontitis and female infertility-associated conditions, and to discuss warranting steps in future research.
La construcción de puntos de vista en la escritura escolar
Authors: Michelan de Azevedo Isabel Cristina , Dos Santos Matos Jussara
Published: June 2020

Este artículo analiza cómo promover la construcción de puntos de vista (PDV) entre los estudiantes de noveno grado de la escuela primaria, quienes están inscritos en una escuela pública en Sergipe, Brasil, cuando se posicionaron en relación con problemas sociales que afectaron sus vidas. Como se considera una categoría que está en el centro del diálogo (RABATEL, 2005), el PDV muestra un cruce de perspectivas, por lo tanto, se puede desarrollar en base a diferentes recursos lingüísticos, entre los cuales se encuentran las estrategias de construcción implícitas y la dirección de operadores argumentativos, que están vinculados a propósitos comunicativos. Los resultados obtenidos, a través de una investigación de acción, son el resultado de la articulación entre las prácticas de enseñanza y las producciones de los estudiantes realizadas en clase. Se observó que a los estudiantes les resulta fácil establecer relaciones entre textos y contextos sociales, pero tienen dificultades para comprender y utilizar los elementos lingüísticos que colaboran con la organización de una posición discursiva. Sin embargo, esto no impidió que los estudiantes participaran en prácticas de lenguaje en las que debían explicar posiciones sobre problemas sociales.
Enseñar a argumentar en la escuela secundaria
Authors: Majorel Cecilia , Padilla Constanza , Rosconi María Gabriela , Moisés Fabiana María
Published: June 2020

Diversas investigaciones en diferentes contextos educativos han evidenciado las dificultades de los estudiantes de escuelas secundarias para comprender textos de cierta complejidad y para fundamentar la propia postura ante diversos contenidos disciplinares. En Argentina, los estudios se han focalizado en estudios diagnósticos sobre la comprensión de textos narrativos y expositivos, pero no en los efectos de la implementación de propuestas didácticas que favorezcan la comprensión y producción de textos argumentativos. En este artículo, se sintetizan los resultados de una investigación colaborativa, realizada en una escuela secundaria pública del noroeste argentino, cuyo objetivo fue el diseño, implementación y evaluación de estrategias didácticas que priorizan el desarrollo de prácticas argumentativas dialógicas para promover el pensamiento crítico -en sentido amplio- (Paul y Elder, 2003), en el aprendizaje de la Filosofía. Se triangularon resultados obtenidos de tres fuentes de datos: producciones estudiantiles, perspectivas de los estudiantes y del docente, y las secuencias didácticas implementadas.
IT-КЛАСТЕРИ В УКРАЇНІ: ЕКОНОМІЧНИЙ ПОТЕНЦІАЛ
Authors: БАЙ Сергій , ПРИСЯЖНЮК Анна
Published: June 2020

Як організаційна форма економічних відносин кластери відіграють ключову роль у проектах розвитку регіонів України. У загальній структурі національних кластерів традиційно переважають промислові, аграрні, туристичні, логістичні та торговельні кластери. Проте така їх структура є реальним індикатором технологічної багатоукладності української економіки на рівні стриманого розвитку. Водночас високотехнологічні IT-кластери різної організаційної конфігурації стають гарантами своєчасної інноваційної модернізації та сталого економічного зростання.В Україні практично відсутні програми розвитку інформаційних технологій на рівні регіонів, що значно обмежує доступ IT-кластерів до необхідних ресурсів, зокрема фінансового, інтелектуального та соціального капіталу. Особливо гостро дана проблематика відчувається в рамках бюджетної децентралізації, коли, з огляду на економічну і соціальну неспроможність регіонів до власного самовідтворення, втрачається пріоритетність розвитку IT-кластерів і високотехнологічних галузей у цілому.У процесі дослідження було отримано такі результати та висновки: зміни фінансово-економічного характеру предметно належать до макроекономічного рівня й мають бути визначені в загальнодержавній політиці розвитку кластеризації. Необхідно активно впроваджувати бюджетну децентралізацію, що дозволить посилити фінансову участь органів місцевого самоврядування в розвитку інфраструктурних проектів ІТ-кластерів; послабити податковий тиск на малі й середні ІТ-компанії за рахунок надання податкового інвестиційного кредиту, що передбачає відстрочення сплати податку на прибуток на визначений строк; розробити систему гарантій для ІТ-компаній, які беруть участь у проектах суспільного значення, зокрема при залученні зовнішніх кредитів для створення нових інфраструктурних об’єктів, використання механізму «реального мита» для відшкодування вартості інвестицій.

Published: June 2020

Інтеграція кредитних послуг з інноваційними технологіями створила підгрунтя для розширення можливостей залучення додаткових фінансових ресурсів представниками малого та середнього бізнесу і фізичними особами. Це зумовлює актуальність обраної теми.Обгрунтовано детермінанти розвитку краудлендінгу на базі дослідження його функціонування в системі фінансових технологій та аналізу міжнародних і вітчизняних нормативно-правових актів.Теоретичною та методологічною базою статті стали праці вітчизняних і зарубіжних науковців. Дослідження проведено із застосуванням методів теоретичного узагальнення, порівняльного аналізу, аналізу та синтезу, що дозволило обгрунтувати напрями розвитку краудлендінгу в Україні.Аналіз наукової літератури та міжнародних нормативно-правових актів дозволив виділити операційний, діяльнісний, суб’єктний та договірний підходи до розуміння краудлендінгу. Запропоновано розглядати краудлендінг як діяльність інтернет-платформ щодо задоволення потреб малого і середнього бізнесу та фізичних осіб у фінансових ресурсах за рахунок коштів кредиторів (інвесторів) на основі зворотності й платності. Краудлендінгові платформи виконують організаційну, аналітичну та моніторингову функції. Проаналізовано етапи зародження, розвитку та застосування інноваційних підходів у краудлендінгу.Отже, краудлендінг – складова краудфандінгу, виникненню та розвитку якого сприяв FinTech. Нині специфікою краудлендінгу є міжнародний характер діяльності; орієнтованість на соціальні, енергозберігаючі, інноваційні проекти; захист прав споживачів; управління ризиками кредитування. В Україні необхідно впровадити ліцензування краудлендінгової діяльності. Стосовно P2P- та P2B-кредитування варто встановити вимоги щодо розкриття інформації інтернет-платформами щодо можливих ризиків надання коштів у позику, а також потенціальних позичальників, максимального розміру здійснення разової інвестиції або протягом року. Також важливо внести відповідні зміни до Податкового кодексу України щодо оподаткування доходів, отриманих при наданні коштів у позику через краудлендінгові платформи.

PENSAR EN MOVIMIENTO: Revista de Ciencias del Ejercicio y la Salud, 14(2), 1-34. El presente estudio amplía un metaanálisis realizado recientemente y examina el Efecto de la Interferencia Contextual (EIC), por medio de la técnica metaanalítica. Después de una búsqueda de literatura en once bases de datos digitales y en referencias, 25 investigaciones cumplieron con los criterios de inclusión establecidos para el análisis intragrupo, mientras que 21 estudios para el análisis entregrupos. Bajo un modelo de efectos aleatorios, para el diseño intragrupo se obtuvo un total de 150 Tamaños de Efecto (TE) individuales. Se encontró que el grupo de práctica en bloque (PB) mejoró su desempeño en la adquisición (TE= 0.69; n= 39; IC95%= 0.40 a 0.97) y lo disminuyó en la retención (TE= -0.25; n= 43; IC95%= -0.51 a - 0.02). El grupo de práctica aleatoria (PA) mejoró en la adquisición (TE= 0.79; n= 31; IC95%= 0.43 a 1.16) y no presentó cambio en la retención (TE= 0.12; n= 37; IC95%= -0.12 a 0.38). Para el diseño entregrupos se obtuvo un total de 68 TE individuales y se encontró que en la adquisición el grupo de PB presentó un desempeño mejor con respecto al grupo de PA (TE= -0.15; n= 31; IC95%= -0.32 a -0.01) y en la retención ambos grupos presentan un desempeño similar (TE= -0.02; n= 37; IC95%= -0.20 a 0.26). Los resultados apoyan el EIC en la adquisición. La presencia de variables moderadoras (edad de los participantes, cantidad de intentos, tipo de destreza y validez externa del estudio) confirman que este efecto no se puede generalizar.

Pensar en Movimiento: Revista de Ciencias del Ejercicio y la Salud, 17(2), 1-23. El consumo de bebidas energéticas (BE) ha ido incrementando tanto en estudiantes y personas activas como en deportistas, esto por posible efecto ergogénico. Dichas bebidas contienen, además de calorías, cafeína en combinación con otros ingredientes como taurina, carnitina y vitaminas del complejo B. El objetivo del estudio fue evaluar el efecto agudo de la ingesta de BE en el rendimiento físico anaeróbico, por medio de la técnica de metaanálisis. La metodología consistió en realizar una búsqueda en cinco bases de datos: PubMed, SPORTDiscus, Springer Link, ProQuest y Science Direct. Se seleccionaron los estudios que cumplieron con los criterios de elegibilidad: experimentales, en los que se midiera el rendimiento anaeróbico y donde se suministrara una BE, realizados en seres humanos, que presentaran la estadística descriptiva y estuviesen publicados en idioma español o inglés. Como resultados se incluyeron 15 estudios que generaron 37 tamaños de efecto (TE) y un total de 253 sujetos (hombres y mujeres; 21,7±3,7 años). Bajo el modelo de efectos aleatorios y un diseño entre grupos se obtuvo un TE global de 0.123 (p = 0.009; IC95% = 0.01 a 0.23; Q = 19.5; p= 0.98; I2 = 0.00%). No se encontró ninguna relación o diferencia en las variables moderadoras. En conclusión, el TE global indica que hay diferencia significativa entre consumir BE o placebo para pruebas anaeróbicas específicas de saltos.
When All Comes Crumbling Down
Authors: Lundberg Anders Per
Published: June 2020

Based on ethnographic research in a local RCCG congregation, the Jesus House in Midtown, Sweden, this article focuses on the meaning of pastorship to its founding pastor, John, and on the nature of the relationship between John and his congregation. Results show that to John, pastorship means hard work but also an opportunity for social mobility. As he founded the Jesus House, John took on considerable financial risk, realistically turning him into a church-owner. Furthermore, the relationship between pastor and congregation implies a contract where John is expected to protect his congregants from illness and death. As a congregant dies, a crisis hits and the congregation starts to break apart. In order to save his congregation, John first appeals to his own spiritual powers, but then resorts to pleading to the structures of plausibility within the congregation. As the paper argues, this shows the importance of both cognitive and relational aspects of meaning-making.

Prediction of soil loss due to erosion using support vector machine model
Authors: Tran Van Quan , Prakash Indra
Published: June 2020

Soil erosion refers to the detachment and removal of soil particles from land (topsoil), by the natural physical forces (water, glacier and wind). Soil erosion causes soil loss in the catchment or any land areas severely impacting agriculture activity, sedimentation in the dam reservoirs, and hampering developmental activities. Therefore, it is desirable to accurately measure soil loss due to erosion for the development and management of an area. With this objective, a well-known machine learning algorithm Support Vector Machine (SVM) has been used in the development of the soil loss prediction model. Eight erosion affecting variable inputs: ambient temperature Tair, rainfall, Antecedent Moisture Conditions (AMC), rainfall intensity, slope, vegetation cover, soil temperature Tsoil and moisture of the soil. Data on published literature was used in the model study. The accuracy of the proposed SVM was assessed by using three statistical performance evaluation indicators namely Person correlation coefficient (R), Root Mean Squared Error (RMSE), Mean Squared Error (MAE). Partial Dependence Plots (PDP) was used to investigate the dependence of prediction results of eight input variables used in the model study. Model validation results showed that SVM model performed well for the prediction of soil loss for testing (R = 0.8993) and also for training (R=0.9123). Rainfall intensity and vegetation cover were found to be the two most important affecting input parameters for the soil loss prediction.

Abstract Background The Brazilian Ministry of Health, by the National Policy on Medication, Ordinance 3916 from October 30th 1998, reinforces the Law of Generics of February 1999 (Law No. 9787 from February 10th, 1999, aiming, among other things, to reduce the prices and make access to medications easier for population). Objective The main objective was to identify the level of knowledge of the population regarding generic drugs. Method Descriptive, quantitative study, with 520 users interviewed in four health care units that implemented the Brazilian Family Health Program. Such units represent four health districts in Foz do Iguaçu, PR, Brazil. Results Most of the interviewed know and/or have heard about generic drugs. For many people, the generic drug represents only a more affordable type of medication. Conclusion The need for health education to clarify the population’s questions was found, so they could identify and acquire their medication safely and with confidence.
A Metodologia ativa de instrução pelos colegas associada à videoanálise de experimentos de cinemática como introdução ao ensino de funções

Published: June 2020

Como resultado de estudos para aplicações interdisciplinares desenvolvidos em curso de Mestrado em Ensino de Ciências, com o intuito de orientar professores e graduandos de licenciatura das áreas de Física, Matemática e afins para práticas inovadoras junto ao corpo discente, o presente estudo trata do ensino de funções em turmas de 9° ano do Ensino Fundamental, envolvendo a Matemática e a Física, a partir do delineamento quase-experimental de série temporal. Por meio da videoanálise de pequenos experimentos de cinemática realizados pelos alunos, com a utilização do software livre Tracker, foram tratadas questões acerca de funções afins e quadráticas, derivadas dessas experiências e observações, com pré-testes e pós-testes conceituais ao longo de seis aulas duplas, intercalando a realização dos experimentos físicos e a aplicação dos testes. A videoanálise dos experimentos de cinemática, com conclusões alcançadas pelos alunos, entrou como fator introdutório e embasador do tema funções. Os pré e pós-testes foram mediados pela metodologia ativa de Instrução pelos Colegas - IpC e a troca de entendimentos e experiências entre os grupos participantes possibilitou a avaliação e medição do estudo quanto à sua eficácia. O tratamento foi aplicado em três turmas de uma escola da Fundação de apoio à Escola Técnica do Rio de Janeiro, totalizando a participação de 76 alunos. Os resultados desta pesquisa, obtidos no desenvolvimento das atividades, estudados pela análise estatística do ganho normalizado de Hake sob o delineamento quase-experimental, indicam a possibilidade de se utilizar a metodologia ativa proposta como potencial mediadora da relação ensino-aprendizagem em contextos colaborativos.
MANUTENÇÃO DO TÓPICO DISCURSIVO DE RESENHA DE ESTUDANTES COM AUTORIA COMPARTILHADA EM ESCRITA COLABORATIVA NA WIKI
Authors: Paiva Francis Arthuso
Published: June 2020

Resumo A escrita colaborativa é realizada com a participação de escritores em autoria compartilhada. As características da escrita colaborativa - como grupo chegar a consenso prematuramente, pouca comunicação e um integrante não enxergar o trabalho do outro - geram diferenças estilísticas e edições inconscientes, que causam problemas de coerência. O objetivo é verificar a manutenção do tópico discursivo de resenha produzida em colaboração em portal wiki por estudantes de Ensino Médio. A hipótese é que a manutenção do tópico discursivo na escrita colaborativa fosse mais trabalhosa para os escritores envolvidos, uma vez que exige negociação de consenso do grupo. A manutenção do tópico discursivo foi verificada, e foi realizada entrevista com o grupo para análise dos dados. O resultado aponta relação de causa e efeito entre características da escrita colaborativa e manutenção do tópico, que prejudicou a produção de coerência na resenha.
#ELESIM, #ELENÃO, #ELASIM, #ELANÃO: O TWITTER E AS HASHTAGS DE AMOR E DE ÓDIO NA CAMPANHA PRESIDENCIAL BRASILEIRA DE 2018

Published: June 2020

Resumo Considerando o uso difundido de hashtags no Twitter, o objetivo deste artigo é analisar seu uso para manifestar amor e ódio aos candidatos à presidência da república em 2018. O arcabouço da Teoria da (Im)Polidez constitui a base para análise dos dados, assim como estudos acerca do estilo conversacional digital (SCOTT, 2015). De 6 de setembro a 6 de outubro de 2018, postagens dos candidatos, bem como de seus seguidores, foram coletadas diariamente, totalizando cerca de 3000 tuítes. Em geral, os resultados indicam que as hashtags atuaram como estratégia para intensificar manifestações de apoio a um determinado candidato por meio de postagens feitas no perfil de seu concorrente, sendo também usadas para manifestar ataque explícito e não racionalizado a rivais. Ademais, as hashtags apresentavam conteúdo derrogatório e injustificado, além de pouco elaborado e superficial. Esse uso aponta para um antidebate, marcado, paradoxalmente, por apoio e ataque, e impolidez linguística.
"TU SABE? TE LEMBRA?": O RESGUARDO DE INFORMAÇÕES EM INTERROGATÓRIOS POLICIAIS POR MEIO DA (COM)POSIÇÃO DE PERGUNTAS E RESPOSTAS
Authors: Konrad Paola Gabriela , Ostermann Ana Cristina
Published: June 2020

Resumo Este artigo analisa sequências de perguntas e respostas em um evento institucional por elas permeado: o interrogatório policial. Investiga, pela perspectiva teórico-metodológica da Análise da Conversa Multimodal, como acontece o resguardo de informações acerca dos crimes em interrogatórios policiais de três Delegacias de Polícia Civil. A análise dos interrogatórios gravados em áudio e/ou vídeo evidencia que esse resguardo, além de ser realizado nas respostas dos interrogados acusados por crimes é, também, oportunizado pelos próprios policiais em suas perguntas. Os interrogados resguardam os fatos dos crimes ao resistirem ao provimento das informações solicitadas, fornecendo respostas cujas ações consistem em declarações de desconhecimento, deslembrança e dessaber, dentre outras. Já os policiais oportunizam esse resguardo ao realizarem perguntas que integram a seleção lexical de verbos como saber e lembrar, possibilitando - e até mesmo facilitando - que os interrogados respondam dessaber e/ou deslembrar a informação solicitada sem resistir ao formato da pergunta.

Avaliando a leitura de palavras isoladas e a compreensão de texto escrito, foram identificados 49 BL e 37 LDC dentre 336 estudantes de 8ª série de escolas públicas na região sul do Brasil, excluindo da análise o grupo de desempenho intermediário. A investigação do perfil dos grupos utilizou um questionário escrito a que os participantes responderam. Os resultados mostram diferença na experiência dos grupos com a leitura e correlação positiva entre o desempenho em compreensão leitora e o número de livros lidos pelos estudantes ao longo de um ano. O estudo constata que a pesquisa sobre os hábitos de leitura dos grupos pode auxiliar na compreensão das diferenças no perfil de BL e LDC, necessitando ser expandida futuramente para orientar tanto estudos teóricos quanto práticos de intervenção clínica e pedagógica.
INVERSÃO DA POSSE: INTERFACE ENTRE LÍNGUA E DISCURSO NO PORTUGUÊS BRASILEIRO

Resumo Este artigo investiga, por meio de uma interface entre morfossintaxe e análise do discurso, a inversão das relações de posse em construções do tipo ‘sou seu x’, em que x é substituído por uma função social de parentesco ou proximidade. Os dados analisados foram coletados a partir de uma metodologia específica em site de busca com vistas a observar a ocorrência de seis construções em contexto de uso (i) ‘sou seu marido’; (ii) ‘sou sua mulher’; (iii) ‘sou seu pai’; (iv) ‘sou sua mãe’; (v) ‘sou seu amigo’; (vi) ‘sou sua amiga’. Nesse tipo de construção, a interpretação de posse, não raro, funciona de modo invertido. Com efeito, o termo nominal possuído, em nível morfossintático, torna-se termo possuidor no discurso, especialmente em dizeres autoritários.

Resumo Diversificados e produtivos caminhos de estudo da palavra têm se instituído no campo das ciências da linguagem. Neste artigo, o objetivo é delinear considerações epistemológicas e teórico-metodológicas a respeito do estudo da palavra como signo ideológico, a partir dos escritos do hoje denominado Círculo de Bakhtin e, mais especificamente, de M. Bakhtin, V. Volóchinov e P. Medviédev. Para tanto, o artigo revisita o conjunto desses trabalhos e retoma as principais considerações desenvolvidas, centradas na relação constitutiva existente entre signo-ideologia-palavra. O estudo pretende contribuir para a compreensão da palavra como dimensão semiótico-ideológica, situando a relevância dessa discussão para os estudos de língua/linguagem na perspectiva enunciativo-discursiva e na consolidação dos estudos discursivos que, no Brasil, são denominados Análise Dialógica do Discurso (ADD).
EL LENGUAJE Y LA VIDA: APORTES TRANSDISCIPLINARIOS DEL ANÁLISIS POLÍTICO DEL DISCURSO PARA PENSAR LÓGICAS DE IDENTIDAD EN PUGNA EN EL ESPACIO SOCIAL
Authors: Enrico Juliana
Published: June 2020

Resumen El horizonte teórico del Análisis Político del Discurso (Political Analysis of Discourse, o APD) afirma la ontología política de toda identidad, desde una particular concepción del lenguaje, de los discursos sociales y del sujeto. Cuando postula la imposibilidad última de la sociedad como totalidad significante plena y establemente articulada, esta perspectiva transdisciplinaria indaga la conflictividad inherente a la historicidad y contingencia de todo proceso identitario, analizando las luchas por la hegemonía alrededor de diferencias y antagonismos circulantes en el espacio social. El APD incorpora herramientas conceptuales de diferentes campos de conocimiento (tales como la lingüística post-estructuralista, la teoría política postmarxista, el psicoanálisis lacaniano y el pensamiento filosófico de la deconstrucción). En este escrito expondremos una revisión y valoración de sus principales aportes al análisis social desde América Latina, en tanto constituye una particular elaboración epistemológica para abordar la dimensión político-discursiva de las disputas por la hegemonía y el sentido.

ABSTRACT The objective of this study was to evaluate the efficiency of black oat (Avena strigosa Schreb) crops in recovering soil aggregation, and quantify the nutrient contents in aggregates considering their formation pathways (biogenic and physicogenic) in crop areas in a mountains environment in the municipality of Nova Friburgo, RJ, Brazil. The landscape was stratified into two sections for the study: upper, two areas with black oat crops, one fertilized and one not fertilized one not fertilized, and one adjacent forest area representing the original soil conditions; and lower: one fertilized area with black oat, and one fertilized area with black oat intercrops with oilseed radish (Raphanus sativus L.) and vetch (Vicia sativa L.), and one adjacent forest area representing the original soil conditions. The aggregates were separated according to their formation pathways, quantifying the weight percentage of each formation pathway. The aggregate stability and nutrient and organic carbon contents were evaluated. The fertilized area in the upper section had the highest biogenic aggregate percentage, which was associated with the highest total organic carbon contents, and soil fertility. This area also had the highest weighted mean diameter (WMD) and geometric mean diameter (GMD) of aggregates. The intercrop area in the lower section had the highest biogenic aggregate percentage and the lowest P, Ca+2, Mg+2, and K+ contents in the aggregates. The management systems affected the aggregate formation pathways. Morphological classification is an important tool for the monitoring of soil management. The black oat crops increased the biogenic aggregate formation, which become reservoir of nutrients.

ABSTRACT Genotypes can respond differently to environments; thus, studies on adaptability and production stability are important to assist breeders in the identification and recommendation of cultivars. The objective of this work was to determine the adaptability and production stability of cowpea genotypes focused on subsidize recommendations of cultivars for green grain production in the state of Ceará, Brazil. Five assays were conducted in different locations in two climatic regions of the state of Ceará: a tropical mild hot semiarid region encompassing the municipalities of Acaraú, Pentecoste, and Crato, and a tropical hot semiarid region encompassing the municipalities of Mauriti and Madalena. Twenty cowpea genotypes-12 elite lines and 8 cultivars-were evaluated for cultivation value and use, using a randomized block design, with four replications. The results were subjected to analyses of variance and adaptability and green grain yield stability analyses by GGE biplot multivariate analysis. The effects of genotypes, environments, and G×E were significant, denoting different responses of genotypes in different locations. The results of the adaptability and stability analyses by the GGE biplot method showed that the two principal components explained 72.17% of the total variation, allowing reliable bidimensional projections. The municipality of Crato was the ideal location for tests and the lines MNC05-847B-123 and MNC00-595F-27 showed good production, adaptation, and stability, and can be recommended for green grain production in the state of Ceará, Brazil.

ABSTRACT This study aimed to evaluate the effect of chemical desiccants and harvest times on the enzymatic expression and physiological quality of soybean seeds. The experiment was carried out in a randomized block design with four replications, in a factorial scheme (4 × 3 + 1) with four desiccants (paraquat - 2 L ha-1, ammonium glufosinate - 2 L ha-1, diquat - 1.5 L ha-1, and saflufenacil - 40 g ha-1). These were applied at the phenological stage R7.1 (beginning of leaf yellowing) and at three harvest times (0, 14, and 28 days after the phenological stage R8). There was also a control treatment (no desiccant, harvested at R8). The physiological quality of soybean seeds and the enzymatic expressions of malate dehydrogenase, alcohol dehydrogenase, esterase, isocitrate lyase, and superoxide dismutase were evaluated in laboratory tests. Seeds harvested at the R8 + 14 stage led to the highest losses in seed quality. However, the 50 mm rainfall also affected seed deterioration. The desiccants diquat and paraquat provided the lowest and the highest damage to the seed physiological quality, respectively. The expression of the enzymes alcohol dehydrogenase, esterase, and isocitrate lyase were efficient and had an adequate correlation with the physiological quality. Malate dehydrogenase and superoxide dismutase had no satisfactory relation with the physiological tests performed with soybean seeds.

ABSTRACT Dry land systems spread all over the world and comprise 41.3% of the terrestrial area, which host 34.7% of the global population, so it is convenient to propose crops able to grow there. Jatropha curcas is a plant adapted to arid and semiarid regions as well as sub-humid conditions, being a potential source of biodiesel. The challenge is to understand the physiology of J. curcas, which enables it to live under saline and drought conditions. The seeds of J. curcas used came from Ciego de Ávila Province, Cuba. Seven-day-old seedlings were cultivated in 1.5 L pots with half strength Hoagland solution for 42 days under semi-controlled conditions. NaCl added to solutions in pots provided 75 or 150 mM treatments for 240 h before measurements. Leaf growth, net photosynthesis and stomatal pore area were affected by 150 mM NaCl. Non-photochemical quenching of leaves was only changed by 150 mM NaCl after 24 h; the electron transport rate had a tendency to decrease in leaves under saline conditions. The gene expression pattern changed for SOS1 and HKT1 according to the NaCl used in the medium, indicating active mechanism to deal with Na+ in the cell. In general, Cuban J. curcas plants were able to grow and perform photosynthesis under 75 mM NaCl, which represents 7 dS m-1, a condition that restricts growth for many plant species.

ABSTRACT In semiarid areas, the scarcity of water with low salt concentration associated with irregular precipitation becomes a limiting factor to ensure agricultural production. In this context, the objective of this study was to evaluate the growth and production of sesame genotypes under different strategies of use of saline water. The experiment was conducted under protected environment conditions, using a randomized block design in a 6 x 2 factorial scheme, and the treatments consisted of six strategies for the use of saline water in the different stages of plant development (SE = irrigation with low-salinity water throughout the cultivation cycle; VE, FL, FR, VE/FL and VE/FR - respectively, irrigation with high-salinity water at the vegetative stage, flowering, fruiting, vegetative/flowering and vegetative/fruiting) and two sesame genotypes (BRS Seda and BRS Anahí), with 4 replicates. Irrigation with high-salinity water (ECw = 2.7 dS m-1) during the vegetative, flowering and fruiting stages did not compromise sesame production. There were reductions in sesame growth when irrigation with high-salinity water was continuously applied at the vegetative/flowering stages and in sesame production when it was applied during the vegetative/flowering and vegetative/fruiting stages. The greater growth of BRS Seda sesame plants resulted in an increase in the total number of fruits and in the total seed weight.

ABSTRACT Salt stress causes losses in the yields of crops, especially those of great economic and social-food importance, such as passion fruit. The objective of this study was to evaluate the effects of fertilization with calcium silicate on the mitigation of salt stress in yellow passion fruit seedlings. The experiment was conducted in a protected environment, in a randomized block design, arranged in a 4 x 3 factorial scheme, referring to four concentrations of calcium silicate (0; 2.22; 4.44 and 6.66 g per plant) and three levels of irrigation water salinity - ECw (0.5; 1.7 and 4.0 dS m-1), with four replicates, considering five plants as experimental unit. BRS GA1 seedlings were produced in 0.5-dm3 containers filled with a mixture of soil, washed sand and aged bovine manure, in a ratio of 1:1:1 (v:v:v). Plants received calcium silicate applications according to the studied doses in three plots, at 30, 45 and 60 days after sowing. At 90 days after sowing, plants were evaluated for growth and biomass accumulation. The use of water with salinity of 4.0 dS m-1 restricted the growth and biomass accumulation of passion fruit seedlings. The use of calcium silicate at dose of 3.5 g per plant mitigates salt stress in seedlings of passion fruit cultivar BRS GA1 when irrigated with saline water.
