Simbologia de Marielle Franco nas guerras culturais do Brasil polarizado: uma análise discursiva
Authors: Medeiros Priscila , Flores Natália
Published: December 2021

O assassinato de Marielle Franco ganhou centralidade nos debates políticos no Brasil a ponto de a vereadora ser alvo constante de campanhas desinformativas após sua morte. Neste artigo, exploramos a razão de Marielle ter se transformado em um símbolo que incomoda tanto determinado espectro político brasileiro, a partir da análise de discurso. Analisamos os movimentos interdiscursivos de um corpus composto por 38 discursos proferidos pela ex-vereadora na Câmara Legislativa do Rio de Janeiro entre os anos de 2017 e 2018 e 36 textos de notícias falsas divulgadas nas redes sociais após a sua morte. Além de entendermos que, para o campo discursivo rival, a imagem de Marielle se transformou em uma metonímia da própria esquerda, concluímos que, ao questionar o abuso e violência policial nas favelas, o discurso da vereadora tensionava o esquema discursivo binário do conservadorismo punitivo. A sua morte pelas mãos de ex-policiais era uma narrativa que, por ameaçar tal coerência discursiva, foi recontada através de fake news.
Da manosphere à machosfera
Authors: Vilaça Gracila , D'Andréa Carlos
Published: December 2021

Neste artigo, focamos em um conjunto multiplataforma de comunidades online que é autodenominado "manosphere" e que se vale de estratégias de inversão de opressões relacionadas a gêneros, raças, sexualidades e classes para construir suas masculinidades. Buscando compreender a dinâmica transnacional da manosphere e as encruzilhadas contextuais da "machosfera" brasileira, discutimos suas articulações com as Novas Direitas, sua sobreposição com alt-right e sua participação nas guerras culturais online, assim como os entrelaçamentos entre as práticas de homossocialidade e as plataformas baseadas no anonimato, como o Reddit. Introduzimos ainda a "filosofia" da Pílula Vermelha e sua relação com práticas (sub)culturais masculinistas de assédio. Na seção final do trabalho, apontamos chaves de observação que, em pesquisas futuras, podem nos ajudar a desvendar a machosfera brasileira, como a fluidez das masculinidades e posição contextual do Brasil no cenário transnacional de plataformas.Palavras-chave: manosphere – machosfera – guerras culturais online – plataformas anonimizadas – masculinidades
Ressentimento e guerra cultural no populismo de extrema direita:
Authors: Lage Leandro Rodrigues , Saraiva Luiziane Silva
Published: December 2021

O artigo busca reivindicar a relevância dos afetos políticos para a compreensão do bolsonarismo, tomado como fenômeno populista de extrema direita. Parte-se da premissa de que o governo de Jair Bolsonaro institui uma política do ressentimento fortemente articulada a uma guerra cultural. Nesse sentido, investiga-se alguns traços fundamentais do populismo, define-se a ideia de política do ressentimento e discute-se algumas das tensões morais e condições de emergência da política ressentida praticada por Bolsonaro. Por fim, observa-se a práxis discursiva dessa atuação no perfil do presidente da República no Twitter, uma das principais plataformas de visibilidade do chefe do Executivo.
A campanha difamatória contra a exposição Queermuseu
Authors: Miguel Jorge Luiz , Jaremtchuk Dária Gorete
Published: December 2021

Este artigo procura reconstituir a campanha difamatória contra a exposição Queermuseu — cartografias da diferença na arte brasileira, que levou a seu fechamento antecipado em setembro de 2017. Analisando os acontecimentos, observa-se a propagação de pânico moral em relação ao conteúdo de algumas poucas obras expostas, que serviriam como exemplos para difundir a crença de que artistas estariam ligados a uma agenda política de esquerda interessada em corromper moralmente o público, ameaçar crianças e ofender a fé cristã. Pelo poder de manipulação e de influência sobre setores da sociedade, esse caso de censura tornou-se um capítulo significativo da história das chamadas “guerras culturais” no Brasil.

Published: December 2021

Objective: To assess the frequency and association of symptoms of hearing loss among traffic police wardens. Study Design: Observational (Cross-sectional) study. Setting: Karachi, Pakistan. Period: January to June 2019. Material & Methods: Non-probability purposive sampling technique was used to employ 181 traffic police wardens. A self-administered questionnaire translated into Urdu language was used. Written informed consent was taken from the participants. IBM SPSS Statistics version 22 was used for the data entry and analysis. Frequencies were determined of socio-demographic data. Multivariable logistic regression analysis was done to assess the factors associated with tinnitus. Results: Most of the traffic police wardens were young (mean age: 29.96 years), non-smokers (95%) and having a matriculate degree (49.7%). Around 97.8% documented working in noisy places; 98.3% of the wardens did not use any hearing protection devices during work, while 98.9% stated that they never had a hearing test. Multivariable logistic regression showed strong inverse associations of tinnitus with higher education levels, longer duration of work, working in a noisy area, and experiencing sudden noise exposures in their lifetime. Conclusion: Traffic police wardens are exposed to loud noise during work, exhibiting the deleterious health impacts of occupational exposure. This workforce needs to be educated regarding the adverse health impacts of occupational noise pollution, the importance and use of personal protective equipment. Further research is warranted using more quantitative assessment
Hydro-environmental Characteristics of Seawater around Boubyan Island, Kuwait Using Annual Variations of Seawater Temperature, Salinity and Tide Fluctuations
Authors: Subramaniam Neelamani , Al-Osairi Yousef
Published: December 2021

The temporal and spatial variations of seawater temperature, salinity, and tidal fluctuations are important parameters for understanding the hydrodynamic, water quality, and marine biological activity in the seawater. It is also important to study and understand the probability and statistical aspects of these parameters for the planning and implementation of different types of marine projects. These parameters were measured at five different locations around Boubyan Island, Kuwait, for a span of almost one year during 2015-16. Based on the analysis of the measured data, it is found that the seawater salinity has varied from 34.14 to 48.31 ppt. The seawater temperature is also found to vary from 10.83 oC to 35.67 oC.  The seawater level has varied from -2.694 m to 2.378 m with respect to the mean sea level. It is found that the peak of the probability density of seawater level is flat valued, whereas the probability density of salinity and seawater temperature is multimodal.  A comparison of present and past measured seawater temperatures revealed that in Khor Al-Sabiya, the seawater temperature is increasing at the rate of 0.034 oC/year, which clearly indicates the effect of global warming. A similar study reveals that the annual average increase in salinity at Khor Al-Sabiya is 0.38 ppt, which clearly indicates a significant reduction of freshwater flow from Shatt Al-Arab into the Arabian Gulf.  Since Kuwait is investing in many projects around the Boubyan Island, the results of this study will be useful for the integrated and sustainable development of Boubyan and Failaka Islands in Kuwait.

Craniopharyngioma is a rare benign epithelial tumor, originating in the pituitary stem or pituitary gland and developing in the sellar and / or suprasellar region. Of embryonic origin, craniopharyngiomas are considered to develop from epithelial remains of Rathke's pouch. It affects children as well as adults. All ages combined, craniopharyngiomas represent between 3 to 4% of intracranial tumors worldwide, or 0.5 to 2 new cases per year and per million inhabitants. In children, they represent 10% of all intracranial tumors with a peak frequency between 7 and 13 years and a predominance of men. Although benign, this tumor remains a serious pathology because of the frequent visual, endocrine, neuro-intellectual sequelae and the risk of recurrence that it entails, involving the visual and vital functional.The management of this pathology is multidisciplinary and involves several modalities such as surgery, radiotherapy and medical treatment of hormonal deficits very often associated. We report in this article three cases of boys aged 9, 10 and 12; treated for symptomatic craniopharyngiomas with a favorable clinical and radiological outcome after partial surgical excision and adjuvant external radiotherapy. The aim of this article is to review the epidemiological, diagnostic, therapeutic and evolutionary aspects of these benign tumors of the sellar and / or suprasellar region, with an emphasis on the interest of radiotherapeutic treatment.

Published: December 2021

Infrastruktur jalan di Indonesia saat ini sering kali dijumpai kondisi perkerasan jalan yang sering rusak. Salah satu penyebab kerusakan adalah kegagalan daya dukung tanah dasar. Daya dukung yang rendah dan potensi pengembangan yang tinggi yang sering terjadi pada tanah ekspansif. Tanah ekspansif adalah tanah yang memiliki kembang susut yang besar. Bila suatu konstruksi dibangun diatas tanah ekspansif maka akan terjadi kerusakan antara lain retakan pada perkerasan jalan. Salah satu cara yang digunakan untuk mengatasi permasalahan tersebut adalah menstabilkan tanah dengan meningkatkan daya dukung tanah asli. Stabilisasi yang digunakan pada penelitian ini berupa penambahan vermikulit dan lumpur bledug kuwu. Sifat vermikulit yang dapat menyerap air dan  lumpur Bledug Kuwu  yang memiliki bahan penyusun kimia hampir sama dengan fly ash, serta mengandung CaO seperti kapur, maka perlu dilakukan penelitian untuk mengetahui pengaruh penambahan vermikulit dan lumpur Bledug Kuwu terhadap nilai kuat tekan bebas pada tanah lempung ekspansif. Vermikulit yang digunakan sebesar 4% untuk seluruh benda uji, dan variasi dari persentase lumpur Bledug Kuwu sebesar 5%, 10%, 15%. Dari hasil yang didapatkan terjadi kenaikan kuat tekan bebas pada tanah yang telah distabilisasi. Campuran optimum dengan nilai kuat tekan bebas tertinggi dihasilkan dari varian 3 yaitu 4% vermikulit dan 15% lumpur Bledug Kuwu.

The creation of a transportation system that ensures the movement of people, vehicles, and or goods smoothly, safely, quickly, cheaply, comfortably, and by the environment is already a development goal in the transportation sector. The target functional level of the road network will be determined by the level of traffic flow through the road network. Based on data from the Central Bureau of Statistics in 2017, Dumai City has national roads with a total length of 72 km, and provincial roads with a total length of 140 km. Every day nearly thousands of vehicles pass through that road. The trip that is carried out can cause quite a lot of displacement at the same time and has the potential to cause high travel generation. This activity certainly can result in jams. As a national road, Jalan Soekarno-Hatta must meet the requirements of comfort and safety so that traffic on this road can run well. Therefore, it is necessary to evaluate the road performance. The purpose of research is to find out the value of the degree of saturation and the value of the level of service on that road. The evaluation on the research by using PKJI 2014. Of the evaluations carried out, it is known that the Soekarno-Hatta road segment will experience congestion on Saturdays and Sundays. The highest peak hour is on Sunday at 14:00-15:00 WIB with a volume of vehicle 2300 vehicles/hour. Soekarno-Hatta's service level on Monday and Tuesday is in class D, while on Saturday and Sunday, the level of road service is in class F. Thus it can be concluded that the performance of the Soekarno-Hatta road section is classified as poor, so that action is needed for the future.
