Although uremic osteoporosis is a component of mineral and bone disorder in chronic kidney disease, uremic toxin (UT) concentrations in patients with end-stage kidney disease and bone mineral density (BMD) changes after kidney transplantation have not previously been described. We hypothesized that elevated UT concentrations at the time of transplantation could have a negative impact on bone during the early post-transplantation period. Hence, we sought to determine whether concentrations of UTs (trimethylamine-N-oxide, indoxylsulfate, p-cresylsulfate, p-cresylglucuronide, indole-3-acetic acid, hippuric acid, and 3-carboxy-4-methyl-5-propyl-furanpropionic acid) upon transplantation are predictive markers for (i) osteoporosis one month after transplantation, and (ii) a BMD decrease and the occurrence of fractures 12 and 24 months after kidney transplantation. Between 2012 and 2018, 310 kidney transplant recipients were included, and dual-energy X-ray absorptiometry was performed 1, 12, and 24 months after transplantation. The UT concentrations upon transplantation were determined by reverse-phase high-performance liquid chromatography. Indoxylsulfate concentrations upon transplantation were positively correlated with BMD one month after transplantation for the femoral neck but were not associated with osteoporosis status upon transplantation. Concentrations of the other UTs upon transplantation were not associated with osteoporosis or BMD one month after transplantation. None of the UT concentrations were associated with BMD changes and the occurrence of osteoporotic fractures 12 and 24 months after transplantation. Hence, UT concentrations at the time of kidney transplantation were not predictive markers of osteoporosis or fractures.

Published: November 2020

In this study, a rapid and sensitive immunoassay method has been established based on calibration curve implanted enzyme-linked immunosorbent assay (C-ELISA) for the simultaneously quantitative determination of aflatoxin B1, deoxynivalenol and zearalenone in cereal samples, soybean and peanut. The C-ELISA avoids using the standard substances during the detection. The principle of the C-ELISA is to implant the optimized standard curve data into the matched analysis software which can make data processing more convenient and faster. The implanted calibration curve software was programmed with C plus plus. In the new immunoassay system for aflatoxin B1, deoxynivalenol and zearalenone, their linear detection ranges were from 0.03~0.81, 1.00~27.00 and 5.00~135.00 ng/g, respectively. Recovery rates from spiked samples ranged from 85% to 110% with the intra-assay coefficients of variation under 5%. Compared with HPLC method, the new method showed consistence in all the observed contents of the three mycotoxins in real samples. The new method can rapidly and reliably high throughput simultaneously screen for multiplex mycotoxins.

Infectious laryngotracheitis virus (ILTV) is a herpes virus that causes an acute respiratory disease of poultry known as infectious laryngotracheitis (ILT). Chicken embryo origin (CEO) and tissue culture origin (TCO) live attenuated vaccines are routinely used for the control of ILT. However, vaccine virus is known to revert to virulence, and it has been recently shown that ILT field viral strains can undergo recombination with vaccinal ILTV and such recombinant ILT viruses possess greater transmission and pathogenicity potential. Based on complete or partial genes of the ILTV genome, few studies genotyped ILTV strains circulating in Canada, and so far, information is scarce on whole-genome sequencing or the presence of recombination in Canadian ILTV isolates. The objective of this study was to genetically characterize the 14 ILTV isolates that originated from three provinces in Canada (Alberta, British Columbia and Quebec). To this end, a phylogenetic analysis of 50 ILTV complete genome sequences, including 14 sequences of Canadian origin, was carried out. Additional phylogenetic analysis of the unique long, unique short and inverted repeat regions of the ILTV genome was also performed. We observed that 71%, 21% and 7% of the ILTV isolates were categorized as CEO revertant, wild-type and TCO vaccine-related, respectively. The sequences were also analyzed for potential recombination events, which included evidence in the British Columbia ILTV isolate. This event involved two ILTV vaccine (CEO) strains as parental strains. Recombination analysis also identified that one ILTV isolate from Alberta as a potential parental strain for a United States origin ILTV isolate. The positions of the possible recombination breakpoints were identified. These results indicate that the ILTV wild-type strains can recombine with vaccinal strains complicating vaccine-mediated control of ILT. Further studies on the pathogenicity of these ILTV strains, including the recombinant ILTV isolate are currently ongoing.

Published: November 2020

We explored whether influenza vaccination (IV) affects susceptibility to SARS-CoV-2 infection and clinical outcomes in COVID-19 patients in 17,608 residents of the Italian province of Reggio Emilia undergoing a SARS-CoV-2 test. Exposure to IV was ascertained and the strength of the association with SARS-CoV-2 positivity expressed with odds ratios (OR). Rates of hospitalisations and death in those found positive were assessed and hazard ratios (HR) were estimated. The prevalence of IV was 34.3% in the 4885 SARS-CoV-2 positive and 29.5% in the 12,723 negative subjects, but the adjusted OR indicated that vaccinated individuals had a lower probability of testing positive (OR = 0.89; 95% CI 0.80–0.99). Among the 4885 positive individuals, 1676 had received IV. After adjusting for confounding factors, there was no association between IV and hospitalisation (1.00; 95% CI 0.84–1.29) or death (HR = 1.14; 95% CI 0.95–1.37). However, for patients age ≥65 vaccinated close to the SARS-CoV-2 outbreak, HRs were 0.66 (95% CI: 0.44–0.98) and 0.70 (95% CI 0.50–1.00), for hospitalisation and death, respectively. In this study, IV was associated with a lower probability of COVID-19 diagnosis. In COVID-19 patients, overall, IV did not affect outcomes, although a protective effect was observed for the elderly receiving IV almost in parallel with the SARS-CoV-2 outbreak. These findings provide reassurance in planning IV campaigns and underscore the need for exploring further their impact on COVID-19.

Published: November 2020

Ca2+ regulation in equine muscle is important for horse performance, yet little is known about this species-specific regulation. We reported recently that horse encode unique gene and protein sequences for the sarcoplasmic reticulum (SR) Ca2+-transporting ATPase (SERCA) and the regulatory subunit sarcolipin (SLN). Here we quantified gene transcription and protein expression of SERCA and its inhibitory peptides in horse gluteus, as compared to commonly-studied rabbit skeletal muscle. RNA sequencing and protein immunoblotting determined that horse gluteus expresses the ATP2A1 gene (SERCA1) as the predominant SR Ca2+-ATPase isoform and the SLN gene as the most-abundant SERCA inhibitory peptide, as also found in rabbit skeletal muscle. Equine muscle expresses an insignificant level of phospholamban (PLN), another key SERCA inhibitory peptide expressed commonly in a variety of mammalian striated muscles. Surprisingly in horse, the RNA transcript ratio of SLN-to-ATP2A1 is an order of magnitude higher than in rabbit, while the corresponding protein expression ratio is an order of magnitude lower than in rabbit. Thus, SLN is not efficiently translated or maintained as a stable protein in horse muscle, suggesting a non-coding role for supra-abundant SLN mRNA. We propose that the lack of SLN and PLN inhibition of SERCA activity in equine muscle is an evolutionary adaptation that potentiates Ca2+ cycling and muscle contractility in a prey species domestically selected for speed.

Published: November 2020

Dogs are the main reservoir for Leishmania infantum, manifesting from a subclinical to a fatal disease. Limited treatments are available, although new antiparasitics and immunomodulators are pursued. Polyhexamethylene biguanide (PHMB) has a broad antimicrobial spectrum, including antiparasitic activity. Here, we evaluated the potential for Toll-like receptor agonists (TLRa) and PHMB alone, and as polyplex nanoparticles containing PHMB and TLR4 or TLR9 agonists, to selectively kill L. infantum. Susceptibility of L. infantum promastigotes to PHMB, miltefosine, and allopurinol was performed, and the half-maximum inhibitory concentrations (IC50) were determined. Then, DH-82 cells were infected and treated with PHMB alone or combined with TLR4a (MPLA-SM) or TLR9a (CpG ODNs) and allopurinol alone. The IC50 values of L. infantum promastigotes were PHMB (1.495 µM), miltefosine (9.455 µM), and allopurinol (0.124 µM). After infection, treated DH-82 cells displayed a lower percentage (p = 0.0316), intensity (p = 0.0002), and index of infection (p = 0.0022) when compared to non-treated cells. PHMB induced lower percentage of infection alone (p = 0.043), in combination with TLR9a (p = 0.043), and with TLR4a (p = 0.0213). Supernatants were collected and used to measure TNF-α and IL-6 levels. Increased TNF-α was observed after PHMB plus TLR4a, relative to uninfected and infected untreated macrophages (p = 0.043). PHMB combined with TLR4a shows promise as a potential anti-L. infantum drug combination, as well as inducer of proinflammatory response, as demonstrated by decreased infection and increased TNF-α production.

Published: November 2020

Rapid urbanization, population explosion and climate change have threatened water security globally, regionally and locally. While there are many ways of addressing these problems, one of the innovative techniques is the recent employment of Sustainable Urban Drainage Systems (SUDS) which include rainwater harvesting systems (RWHS). Therefore, this paper reviews the design and component of two types of RWHS, the namely roof harvesting system (RHS) and the pond harvesting system (PHS). The performance in terms of quantity and quality of collected rainwater and energy consumption for RWHS with different capacities were evaluated, as well as the benefits and challenges particularly in environmental, economic and social aspects. Presently, the RHS is more commonly applied but its effectiveness is limited by its small scale. The PHS is of larger scale and has greater potentials and effectiveness as an alternative water supply system. Results also indicate the many advantages of the PHS especially in terms of economics, environmental aspects and volume of water harvested. While the RHS may be suited to individual or existing buildings, the PHS has greater potentials and should be applied in newly developed urban areas with wet equatorial climate.

Published: November 2020

The human activities and urbanization process have changed the underlying surface of urban areas, which would affect the recharge of groundwater through rainfall infiltration and may further influence the groundwater environment. Accordingly, it is imperative to investigate the variation of hydrological cycle under the condition of underlying surface change. Based on the high-precision remote sensing data of 2000, 2005, 2010 and 2015, and Soil and Water Assessment Tool (SWAT) model, this work firstly studied the land use change and the corresponding changes in runoff generation mechanism and rainfall infiltration coefficient in Su-Mi-Huai area, Beijing, China. Meanwhile, SWAT-MODFLOW semi-loose coupling model was applied to analyze the water balance in the study area in typical hydrological years. The results showed that the area of the construction land (urban and rural residential land) increased by 1.04 times from 2000 to 2015, which is mainly attributed to the conversion of cultivated land to construction land in the plain area. This change caused the runoff in the area to increase by 7 × 106 m3, the runoff coefficient increased by 17.9%, and the precipitation infiltration coefficient was less than the empirical value determined by lithology. Compared with 2000, the average annual precipitation infiltration coefficient in 2018 decreased by 6.5%. Under the influence of urbanization process, the maximum reduction rate of precipitation infiltration recharge is up to 38%. The study investigated the response of surface runoff and precipitation infiltration recharge to land use change, which can provide helps for water resources managers to coordinate the relationship between land use change and rational water resources planning.

Published: November 2020

Anaerobic digestion (AD) has benefits in sludge management, energy recovery, and pathogen reduction. In order to better understand the mechanisms of biological hydrolysis (BH) pretreatment on AD, biochemical methane potential (BMP) and continuous stirred-tank reactor (CSTR) tests were utilized to compare untreated municipal combined sludge with pilot-scale BH pretreated sludge. During the BH process, there was 15%, 30%, and 33% (w/w) volatile solids (VS) reduction after BH at 42 °C (BH42) for 24, 48, and 72 h, respectively; under BH61 (42 °C for 36 h and 61 °C for 6 h), and there was 10% and 30% (w/w) overall VS reduction after 36-h and 42-h hydrolysis, respectively. BMP results showed that BH42-pretreated sludge had 22.6% enhancement of methane yield compared to untreated sludge, and BH61 pretreated sludge had 29.4% enhancement of methane yield. Both temperature and solids’ retention time (SRT) contributed to the enhanced AD performance within 36 h, while temperature played more important roles after 36-h BH pretreatment. CSTR tests confirmed the acceleration of anaerobic digestion by BH pretreatment, and higher enhancement was observed when SRT of anaerobic digestion was shorter than 16 days. Through a literature review of BH-related studies, the possible mechanisms were highlighted for further optimization on the scale-up systems in order to reduce carbon footprint and operating expenditure for wastewater treatment plants.

Published: November 2020

Lavandula angustifolia was watered with either deionized tap water treated with low-temperature, low-pressure glow plasma of low frequency in the air (LPGPA), under oxygen-free nitrogen (LPGPN), methane (LPGPM), carbon dioxide (LPGPC) or molecular oxygen (LPGPO). The crop yields were slightly dependent on the type of water used for watering. Notably, only plants watered with LPGPN showed a slightly higher crop yield. The plants also contained a higher level of protein and bioaccumulated magnesium. The type of water had a considerable and specific effect on the yield of isolated essential oils and their composition. The yield of essential oil decreased in the following order LPGPA = LPGPN (0.4 g/100 g dry mass) > LPGPC = LPGPO (0.3 g/100 g dry mass) > LPGPM = non-treated water (0.2 g/100 g dry mass). The composition of the isolated essential oils varied depending on the type of water used for watering, which influences their role as a fragrant component of cosmetics, and in herbal therapy and aromatherapy.

Published: November 2020

A nexus approach can support the transition to sustainability by addressing trade-offs and pursuing synergies to improve water, energy, and food security. In this paper, a participatory system dynamics model was developed to identify and assess the key interlinkages between water, food, and energy in Andalusia (Spain). A panel of relevant stakeholders contributed to all stages of the model’s development. Further, by calibrating the model to CAPRI-Water projections until 2050, the evolution of the system under a plausible climate scenario, as well as effects of water prices changes, was evaluated. The results revealed a close link between water cost, irrigation water use, energy consumption, and the economic development of agriculture in the region. Large variability was observed in the effects of water pricing policies across crops. This paper concludes that a participatory system dynamics model can help in understanding the nexus synergies and can support the design of more coherent sustainability strategies in the region.
Impact of the Mean Daily Air Temperature Calculation on the Rainfall-Runoff Modelling
Authors: Bezak Nejc , Cerović Lazar , Šraj Mojca
Published: November 2020

Conceptual rainfall-runoff models besides precipitation and discharge data generally require estimates of the mean daily air temperature as input data. For the estimation of the mean daily air temperature, there are different methods available. The paper presents an evaluation of the impact of the mean daily air temperature calculation on the rainfall-runoff modelling results. Additionally, other measured variables and rating curve uncertainty were assessed. Differences in the mean daily air temperature values were evaluated for the 33 meteorological stations in Slovenia and additional investigations were conducted for four selected meso-scale catchments located in different climates. The results of the application of four equations for the mean air temperature calculation yielded the mean absolute error values between 0.56–0.80 °C. However, the results of rainfall-runoff modelling showed that these differences had an almost negligible impact on the model results. Differences in the mean simulated discharge values were no larger than 1%, while differences in the maximum discharge values were a bit larger, but did not exceed 5%. A somewhat larger impact on the model results was observed when precipitation and water level measurements’ uncertainty was included. However, among all analysed input data uncertainties, the rating curve uncertainty can be regarded as the most influential with differences in the simulated mean discharge values in the range of 3% and differences in the maximum discharge values up to 14%.
Water Price: Environment Sustainability and Resource Cost
Authors: Sanabria Sonia , Torres Joaquín
Published: November 2020

The determination of a price for water is an open discussion among related players, directly or indirectly, in water management. In the context of the recovery of water service costs, as referred to in Article 9 of the Water Framework Directive 2000/60/EC (WFD), legislation applicable in all member countries of the European Union, the total water cost is broken down into three blocks; financial, environmental, and resource. It is the last component that generates the most uncertainty both in its conceptualization and in its valuation. The need to establish a pricing system for water (water tariff) implies that the different concepts that make it up are correctly delimited. The main goal of this paper is to propose a first approximation to a new theoretical framework to establish a relationship between environmental sustainability and the valuation of the resource cost—given that current water consumption can provoke future water availability difficulties, making it a scarce commodity that resource cost must be correctly delimited. Taking into account the prospective nature of environmental sustainability, the measure of its value should be based on the use of stochastic models that reflect the associated uncertainty.
Liberdade de expressão e discurso de ódio sob a perspectiva de John Rawls
Authors: Oliveira Pedro César , Rodrigues Franco Dalton
Published: November 2020

O presente artigo se propõe analisar o panorama da discussão entre liberdade de expressão e o discurso de ódio por meio da literatura acadêmica especializada brasileira e compará-lo com a teoria de justiça formulada por John Rawls, afim de verificar possíveis contribuições do autor para o debate. Os objetivos do trabalho são analisar cada um dos objetos propostos com o escopo de averiguar sua origem, estrutura e desenvolvimento, bem como analisar comparativamente os escritos rawlsianos com a referida bibliografia selecionada. O método escolhido foi o comparativo, valendo-se da técnica documental por meio da revisão bibliográfica. Os resultados alcançados foram que a liberdade de expressão pode ser entendida como um direito social, ao passo que o discurso odioso deve ser mitigado pelo Poder Público por instrumentos efetivos, sem reprimir o direito de se expressar. Nesse sentido, a teoria rawlsiana contribui com um sistema de prevenção e repressão do ódio envolvendo instituições e sociedade civil. Conclui-se que os escritos rawlsianos oferecem com uma nova perspectiva sobre a discussão, podendo contribuir para avanços em políticas públicas.
As gerações de grupos organizados de torcedores no Brasil
Authors: Araripe Pacheco de Souza Eduardo
Published: November 2020

Estudos sobre torcedores de futebol no Brasil, principalmente os que se organizam em grupos (geralmente denominados “torcedores organizados” ou “torcedores uniformizados”), começaram a despertar interesse de pesquisadores sociais a partir da década de 1990, relacionados a temas como a violência nos esportes, comportamento juvenil, grupos urbanos, sociabilidades, entre outros de interesse das ciências sociais. Verdade é que os torcedores redimensionaram a relação torcida/futebol profissional e, especialmente, a relação espectador/espetáculo de futebol, através da mobilização coletiva nos estádios e aparição permanente na mídia. O presente estudo foi desenvolvido através de uma etnografia que pretende a compreensão sobre a organização, comportamento, perfil social e características associativas desses grupos; um processo muito maior, complexo e dinâmico que mudou a forma de pensar o assunto e alicerçou a interpretação sobre a formação das alianças entre torcidas de estados diferentes. A construção do vínculo social (Aliança) entre grupos de cidades diferentes, portanto, é interpretada como uma escolha determinante entre o protagonismo ou a invisibilidade, no contexto do futebol de espetáculo.
Esporte e ideologia no periódico on-line El País Brasil
Authors: Mezzaroba Cristiano , Gonçalves Bitencourt Fernando
Published: November 2020

Resumo: Neste estudo documental, de abordagem qualitativa e exploratória, identificamos e analisamos 103 reportagens no periódico online El País Brasil, produzidas e veiculadas entre janeiro/2019 e fevereiro/2020. A escolha pelo referido jornal ocorreu pela percepção costumeira em relação ao seu posicionamento progressista quando comparado à maioria dos grandes jornais brasileiros. Utilizando-se da análise crítica da ideologia de Thompson (2011), observamos que no conjunto das reportagens coletadas puderam ser elaborados 5 agrupamentos temáticos, os quais foram analisados separadamente, embora consideramos um grau de interdependência entre todos eles: (1) machismo – 39 reportagens que abordaram naturalização do comportamento machista de jogadores e a discussão de ineditismos quanto aos direitos das mulheres no esporte/sociedade; (2) política e fascismo – 20 reportagens que evidenciaram as relações políticas com esporte, bem como, questões envolvendo fascismo e contextos históricos; (3) racismo – 16 matérias que trataram quanto a questões racistas envolvendo o campo esportivo; (4) mercadorização e tecnologias – 16 reportagens em que se explicitam as relações entre esporte, mercado e tecnologias; e, (5) homofobia e preconceitos/assédio sexual – 12 reportagens que explicitaram casos de homofobia e preconceitos sexuais diversos. Concluímos que o esforço do periódico em pautar temas importantes da política contemporânea é limitado pela sua estrutura conservadora, tanto na ordem do discurso quanto no dos interesses econômicos, e propriamente ideológico, pois que sob a aparência progressista junta-se aos esforços de manutenção da ordem do poder.

Propomos neste texto pensar sobre “práticas esportivas dissonantes”, ou seja, aquelas que rompem com a normatividade instituída de esporte, segundo sugere Wagner Camargo, a partir de reportagens veiculadas online sobre a equipe de futsal de homens trans Meninos Bons de Bola (MBB). A emergência de sujeitos trans na prática esportiva a transforma e levanta questões como a ocupação do espaço público de lazer por corpos dissonantes. O potencial disruptivo do futsal do MBB suscita possibilidades outras de prática esportiva, levando-nos a pensar a necessidade de novos modelos de esporte e ampliando a noção do que faz um corpo.

Published: November 2020

Este artículo compara notas sobre diferentes y nuevos conceptos de “lo Humano”, desarrollados ambos hacia el interior de la investigación científica académica, tanto disciplinaria como interdisciplinaria, y en las prácticas sociales más amplias. El foco principal está en la relación cambiante entre las “dos culturas” de las humanidades y la ciencia a la luz de los desarrollos contemporáneos, como las sofisticadas formas de investigación interdisciplinaria que han emergido en los campos de la biotecnología, las ciencias neurales, investigación ambiental y del cambio climático y tecnologías de la Información y la Comunicación. Estos rápidos cambios afectan las vastas definiciones de lo humano y la evolución humana. La pregunta es cómo y en qué grado tienen un impacto en la práctica de las humanidades y sobre su auto-representación. ¿El humanismo se encuentra desafiado o fortalecido por estos desarrollos? ¿A qué grado el antropocentrismo es llamado a la tarea por la que se está volviendo conocido como teoría posthumana?

Three basic economic activities are production, distribution, and consumption. Economic growth can be realized quickly, by maximizing one of the three. Economic growth that can create prosperity can be done in two ways: growth in production factors, both labor, and capital. Economic activities are concentrated in businesses in the form of production, partnerships, sales. The results of this study are there are several roles of the Indonesian Tobacco Farmers Association that were found, in the form of mediator, facilitator, advocacy. And there are also findings in the form of increased taxes and the distribution of tobacco excise revenue sharing funds that are not evenly distributed. There are also several findings, they are: the occurrence of economic activities in the form of partnerships carried out by tobacco farmers and entrepreneurs. The difference lies in the end that there is a transaction of buying and selling witnesses between tobacco farmers and entrepreneurs. So when partnering, the agreement must sell farmers' crops to partners, namely tobacco entrepreneurs. Of course, the transaction has met the provisions of Sharia Economic Law, when the conditions have been fulfilled, the transaction will be considered valid.

Crotalaria retusa e Tephrosia cinerea estão entre as principais plantas causadoras de lesões hepáticas em ruminantes e equinos. O objetivo desse trabalho foi comparar os aspectos epidemiológicos, clínicos e anatomopatológicos de ovinos intoxicados por essas duas plantas. Os principais achados nos ovinos intoxicados por T. cinerea foram ascite, fígado com superfície irregular e reduzido de tamanho e fibrose centrolobular à microscopia. As principais alterações observadas nos animais intoxicados por C. retusa foram distensão abdominal, icterícia, acentuação do padrão lobular e espessamento da cápsula do fígado, além de degeneração, necrose e hemorragia centrolobular e megalocitose de hepatócitos à microscopia. O conhecimento dos aspectos epidemiológicos clínicos e anatomopatológicos das plantas hepatotóxicas são fundamentais para o diagnóstico, favorecendo a adoção de medidas de controle e profilaxia reduzindo as perdas econômicas.

Colangiocarcinoma é um neoplasma maligno oriundo do epitélio de ductos biliares comum em animais de companhia. Descreve-se um caso de colangiocarcinoma em um cão diagnosticado no Hospital Veterinário Universitário da Universidade Federal de Campina Grande, Patos, Paraíba. A cadela de seis anos de idade apresentou discreta icterícia e foi positiva no teste rápido para leishmaniose. O animal foi entanasiado e na necropsia observou-se fígado aumentado de volume com múltiplos nódulos branco-amarelados que se aprofundavam ao parênquima. Baço e linfonodos aumentados de tamanho com nódulos semelhantes aos descritos no fígado. Pulmões não colapsados com múltiplos nódulos brancacentos. Microscopicamente os nódulos observados no fígado, baço, linfonodos e pulmões eram compostos por células neoplásicas com origem de ductos biliares, caracterizando um quadro de colangiocarcinoma com metástase para órgãos da cavidade abdominal e torácica. O colangiocarcinoma metastático deve ser considerado em cães com insuficiência hepática associada à massas no parênquima hepático e em outros órgãos.
The Weight of Harm: A Response to “Editor’s Note: Societal changes and expression of concern about Rekers and Lovaas’ (1974) Behavioral Treatment of Deviant Sex-Role Behaviors in a Male Child”
Authors: Johnson Austin H
Published: November 2020

In 1974, Rekers and Lovaas published an article in the Journal of Applied Behavior Analysis (JABA) wherein the authors coached a 4 year old child’s parents to ignore and physically abuse him when he engaged in behaviors that were identified by the authors as inappropriate for a child whose sex assigned at birth was male. In October 2020, a Statement of Concern regarding Rekers and Lovaas (1974) was published in JABA (SEAB & LeBlanc, 2020) which described concerns regarding the paper and then provided justification for the journal’s decision to not retract this paper. In this current response, I provide a counterpoint to the Statement of Concern, arguing that (a) the available evidence strongly suggests that the original study was unethical and misaligned with the principles of ABA, and (b) the evidence presented to support its contemporaneous ethicality is insufficient. I end with an argument that Rekers and Lovaas (1974) should be retracted and discuss the critical role of ethics and social significance for the field of ABA.

As atividades práticas são ferramentas didáticas de suma importância no processo de ensino-aprendizagem, pois despertam no educando o interesse pelo ensino, além de proporcionarem uma melhor assimilação dos conteúdos ministrados na disciplina de Ciências. O presente trabalho, de cunho quantitativo, teve como objetivos analisar os tipos de atividades práticas desenvolvidas por professores de Ciências, verificar a frequência com que ocorrem no cotidiano da escola, identificar as dificuldades dos professores para sua realização e conhecer como os docentes percebem a importância das atividades práticas, como recurso pedagógico facilitador do processo de ensino-aprendizagem. Primeiramente realizou-se uma revisão bibliográfica, posteriormente aplicou-se um questionário semiestruturado com 12 professores que lecionam a matéria de Ciências no Ensino Fundamental II da Rede Pública Municipal de Guanambi/BA. O resultado da pesquisa revelou que as professoras utilizam as atividades práticas no processo de ensino para estimular a construção do conhecimento e motivar os alunos. Contudo, relataram as dificuldades na realização de atividades práticas, pontuando: a ausência de um local adequado para a realização das ações, a pequena quantidade de material disponível e o elevado número de estudantes por sala de aula. As professoras apontam o quanto é importante a realização de atividades práticas no Ensino de Ciências, pois proporcionam um aprendizado mais prazeroso, se comparadas às aulas meramente expositivas.
 
Abstract
Practical activities are didactic tools of paramount importance in the teaching-learning process, as they arouse students’ interest in learning, in addition to providing a better assimilation of the contents taught in Science. The present work has a quantitative nature. It aimed at analyzing the types of practical activities developed by Science teachers, verifying the frequency they occur in the school, identifying teachers’ difficulties to carry them out and to know how teachers perceive the importance of practical activities, as a pedagogical resource that facilitates the teaching-learning process. First, a bibliographic review was carried out, then a semi-structured questionnaire was applied with 12 teachers who teach Science in Elementary School II of the Municipal Public Network of Guanambi/BA. The result of the research revealed that teachers use practical activities in the teaching process to stimulate knowledge construction and motivate students. However, they reported the difficulties in carrying out practical activities, pointing out: the absence of an adequate place to carry out the actions, the small amount of available material and the high number of students per classroom. The teachers point out how important it is to carry out practical activities in Science Teaching, as they provide a more pleasurable learning, when compared to merely expository classes.

Okoubaka aubrevillei is an indigenous and sacred tropical tree in Africa. It is rare with allelopathic properties and has relatively little information available in terms of what is responsible for its usage for medicinal and traditional usage. The phytochemical screening and quantitative analysis of the compounds in the barks and leaves of Okoubaka aubrevillei was determined to ascertain and establish its earlier claimed usage as traditional and modern medicine. The most important classes of secondary metabolites (phytochemical compounds) specifically alkaloids, flavonoids, tannins, saponins, anthraquinnes, mucilages, oses, holosides, coumarin and glycosides were detected in both, the leaves and barks of the tree. Quantitative determination of the phytochemical compounds found in the barks and leaves of the tree revealed that the leaves of O. aubreville tree had significantly higher values of alkaloids, flavonoids and glycosides than barks. Saponins and anthraquinnes were found to be significantly more in barks than in leaves. However, there was no significant difference found in the values of tannins, mucilages, oses and holosides and coumarin in barks and leaves of O. aubreville trees.
