Imagem do rádio
Authors: Antonio Argolo Silva Neto  
Published: July 2023

Pesquisa publicada no livro “Imagem do Rádio”. Aborda a audição radiofônica como um campo privilegiado, que ao saturar apenas um órgão do sentido (o ouvir) potencializa o homem em sua amplitude simbólica. A necessidade do ouvir aproximou a audiência brasileira ao mundo à custa da “radiodifusão internacional” via Ondas Curtas. Estava no ar a Guerra Fria transmitindo no rádio, em português, as questões políticas, ideológicas e culturais polarizadas nos esforços do conflito. Este objeto de análise inicia com o fluxo das emissões políticas, décadas de 70 e 80. À frente o universo se amplia com o sinal de outras rádios internacionais que não atuaram do discurso de combate, permitindo o contraponto das informações. No Brasil há uma audiência segmentada nesse tipo de escuta por questões culturais e afetivas. Ao delimitar esse conjunto de ouvintes o livro pontua o sentido da audiência e faz uma análise iconográfica dos cartões QSLs recebidos. As imagens permitem identificar as emissoras sintonizadas, a sua radiografia, suas pautas, formas de propagandas e construções simbólicas entre emissor/receptor. Esse quadro radiofônico apresenta percepções das formas culturais elementares ao homo symbolicus.

Published: July 2023

Este artigo discute sobre a criação de novas faculdades de medicina no país e em quais condições: se apenas onde haveria carências desses profissionais ou se em qualquer lugar do país. Trata-se de um processo que estava em suspenso desde 2018, e que objetivou controlar a quantidade de cursos de graduação em medicina instalados no Brasil. Observou-se que todas as iniciativas aqui descritas objetivam minimizar a falta de acesso da população a uma assistência médica de qualidade, principalmente nas regiões onde há extrema pobreza e escassez de assistência médica e social.
Eigenvalue estimates for 3-Sasaki structures
Authors: Nagy Paul-Andi , Semmelmann Uwe 
Published: July 2023

Abstract
We obtain new lower bounds for the first non-zero eigenvalue of the scalar sub-Laplacian for 3-Sasaki metrics, improving
the Lichnerowicz–Obata-type estimates by Ivanov, Petkov and Vassilev (2013, 2014). The limiting eigenspace is fully described in terms of the automorphism algebra.
Our results can be thought of as an analogue of the Lichnerowicz–Matsushima estimate for Kähler–Einstein metrics. In dimension 7, if the automorphism algebra is non-vanishing, we also compute the second eigenvalue for the sub-Laplacian and construct explicit eigenfunctions. In addition, for all metrics in the canonical variation of the 3-Sasaki metric we give a lower bound for the spectrum of the Riemannian Laplace operator, depending only on scalar curvature and dimension. We also strengthen a result pertaining to the growth rate of harmonic functions, due to Conlon, Hein and Sun (2013, 2017), in the case of hyperkähler cones. In this setup we also describe the space of holomorphic functions.

Reverse time migration for imaging periodic obstacles with electromagnetic plane wave
Authors: Cai Lide , Chen Junqing 
Published: July 2023

Abstract
We propose novel reverse time migration (RTM) methods for the imaging of periodic obstacles using only measurements from the lower or upper side of the obstacle arrays at a fixed frequency.
We analyze the resolution of the lower side and upper side RTM methods in terms of propagating modes of the Rayleigh expansion, Helmholtz–Kirchhoff equation and the distance of the measurement surface to the obstacle arrays, where the periodic structure leads to novel analysis.
We give some numerical experiments to justify the competitive efficiency of our imaging functionals and the robustness against noises.
Further, numerical experiments show sharp images especially for the vertical part of the periodic obstacle in the lower-RTM case, which is not shared by results for imaging bounded compactly supported obstacles.

Published: July 2023

This study aims to determine the effect of applying active learning model type index card match on students’ higher order thinking skills. The type of this study is quasi-experimental research. The quasi-experimental design used was a nonequivalent control group design. The population in this study were all Class XI Social Sciences students at Public High School 2 Tilatang Kamang for the 2021/2022 academic year. Sampling in this study used simple random sampling technique of 52 respondents. The data analysis technique used Two-Way ANOVA with the SPSS version 22 program. The data collection method used test, questionnaires, and observation sheet. Based on the results of the research and data analysis, it can be concluded that the higher order thinking skills of students who are taught with the index card match learning model are significantly higher than those taught using the conventional learning model, the higher order thinking skills of students who have high learning activities is significantly higher than students who have low learning activities, and the index card match learning model and learning activities do not interact with each other in influencing students’ higher order thinking skills, which means that the two factors do not simultaneously exert their influence.
The Strategies of Sufi Discourse in Fostering Communal Immunity: The Sufi as a Nomadic Subject
Authors: Bouchoir Tayeb 
Published: July 2023

This paper examines the strategies that Sufis adopted during covid-19 crisis which are journey and seclusion: two strategies that characterize Sufi’s behaviour. Using qualitative research, this paper argues that though the policies enacted in the time of covid-19 has led humanity into herd immunity in which bodies have been subjected to a set of improvised political decisions, Sufi bodies are immune bodies by nature, as they are characterized by an inner immunity that makes of them either in a state of journey or in a state of seclusion. Drawing from Rosi Braidotti (2011) ’s poststructuralist notion of nomadic subjectivity, this paper also states that the Sufi can be seen as a ‘nomadic subject’ able to experience not only physical journey shaping the move from one territory to another but also a kind of non-physical journey pertaining to spiritual ascension shaping the path to God. As a result, Sufi discourse is a site for fostering communal immunity where individuals are provided with strategies to transcend not only the pandemic as a temporary disaster but also the problems of life as well as the challenges menacing humankind.

Published: July 2023

Background: Pre-eclampsia (PE) is a hypertensive disorder in pregnancy and a significant cause of maternal and perinatal mortality and morbidity. Failure of spiral artery remodeling due to abnormal apoptosis, triggers disturbances in the mother and the baby’s growth. This study aimed to identify the profile of apoptotic marker genes and histopathological features of the placenta in pregnancies with pre-eclampsia.Methods: This study had used case-control method. Samples were taken from normal pregnancies (n25) and pregnant women with pre-eclampsia (n25) using a purposive sampling method from several hospitals in Jambi. qRT-PCR was used to examine apoptotic gene expression from placental tissue and hematoxyline eosin staining to view the placenta’s microscopic appearance. The targeted genes were BCL2-associated X (BAX) and B-cell lymphoma 2 (BCL-2). Histopathological changes of the placenta observed were syncytial node, cytotrophoblast, villous edema, hypervascularization, fibrosis stroma, atherosis, infarction, and thrombosis.Results: Relative BAX genes expression were increased once in placenta pre-eclampsia compared to controls, but not statistically significant (p-value>0.05). There was no difference between the decline of BCL-2 gene expression in pre-eclampsia placenta compared to the control (p-value>0.05). Histopathological changes in the placenta were syncytial node and cytotrophoblast (100%), villous edema (77.3%), hypervascularization (95.4%), fibrosis stroma (86.4%), atherosis (45.5%), infarction (77.3%) and thrombosis (95.4%).Conclusion: The expression of BAX genes in pre-eclampsia tends to increase compared to normal pregnancy, and the expression of BCL-2 decreases. The histopathological features of pre-eclampsia pregnancy placenta are mostly syncytial nodes, cytotrophoblasts, stromal fibrosis, and thrombosis.

Published: July 2023

Background: Dengue infection is endemic in more than 100 countries; 70% of cases occur in Asia. One of dengue infection complication is hepatic dysfunction. The COVID-19 pandemic may cause a delay in seeking treatment and affect severe case of dengue infection when admitted to the hospital. This study aimed to analyze the liver function profile in dengue pediatric patients during the COVID-19 pandemic.Methods: All patients under 18 with confirmed dengue serology (NS-1 immunochromatography or IgM anti-Dengue (ELISA) test and IgG anti-Dengue (ELISA) test) in Dr. Hasan Sadikin General Hospital from 2021–2022 were included in this retrospective study. The patients were categorized based on the modified WHO classification of 2009. Data were processed with SPSS® ver. 25 and analyzed using Chi-Square and One Way-ANOVA.Result: In total, 85 patients were tested for the liver function; most severe dengue patients had abnormal SGOT and SGPT levels (100% vs. 64%). The SGOT and SGPT levels during the initial admission were higher in the severe dengue group (634 U/l and 271 U/l) and significantly different among groups (p=0.001 and p=0.032). The elevated SGOT (1,339 U/l vs. 203 U/l vs. 87.3 U/l; p=0.014) and SGPT (438 U/l vs. 100 U/l vs. 42.8 U/l; p=0.005) levels were higher in the severe dengue group.Conclusion: The severity of dengue is in line with the increase in SGOT and SGPT levels. During the COVID-19 pandemic, the liver dysfunction persists and may be interfered with by delays in dengue treatment. Early recognition and prompt treatment are needed to decrease morbidity and mortality.

Published: July 2023

A arrecadação tributária é a base sustentável para a função social do Estado e torna-se principal mecanismo para fornecer o bem-estar coletivo. Os fatores determinantes que motivam o cidadão ao recolhimento de impostos são a punição, a moral e a transparência com os gastos. O programa Nota Fiscal Gaúcha foi instituído por meio do decreto nº 49.479/2012 e possui como objetivo fomentar a cidadania fiscal e aumentar a arrecadação, mediante estímulo à emissão de notas fiscais e à participação dos cidadãos na definição da destinação de recursos. O objetivo deste artigo é avaliar o impacto do Programa Nota Fiscal Gaúcha sobre a arrecadação do ICMS do Estado do Rio Grande do Sul. O trabalho utilizou um modelo de diferenças-em-diferenças considerando o período de entrada da política. Os resultados observados apontaram um efeito positivo e significativo do programa sobre a arrecadação geral na arrecadação do ICMS em 4% ao mês no âmbito de todos os setores analisados. Para o setor terciário (serviços) representou um acréscimo de 5% ao mês. As evidências sugerem que programa também produziu efeitos sobre os setores secundário, primário, no petróleo, contudo não significantes sobre o setor de energia. Conclui-se, então, que o impacto do Programa parece ter sido positivo, porém limitado ao desagregar os resultados para diferentes setores.
Navigating multiple languages: The use and effect of code-switching in children from mixed marriage families
Authors: Rahmadani Annisa 
Published: July 2023

The phenomenon of code-switching manifests as the practice of seamlessly oscillating between two or more distinct languages or language variations within the confines of a singular exchange, be it a sentence or a conversation. Children reared in environments rich with linguistic diversity frequently acquire the ability to proficiently maneuver between languages as a mechanism to convey meaning to varied interlocutors or within disparate situational contexts. This study presents a qualitative case study of two children from mixed marriage parents, one of whom is an Indonesian native speaker and the other is an English native speaker. The aim of the study is to explore the use of code-switching and its impact on the language development and proficiency of children from mixed-marriage families. Interviews were conducted with the parents, while observations were made of the children's language use at home. The results suggest that code-switching facilitates the development of children's language skills in different contexts; however, it also hinders their ability to separate and utilize different languages effectively. Furthermore, code-switching enables children to maintain a connection to their cultural heritage and fosters a sense of comfort in multicultural environments.

Published: July 2023

Criticism tends to be a face-threatening speech act that can endanger social relationships if not managed using appropriate strategies, especially in the intercultural context. This study aims to compare and contrast the politeness of criticism speech acts used in Japanese and Minangkabau languages as depicted in film series. The data on criticism speech acts in this study were collected from eleven Japanese film series with a total duration of 538 minutes and eight Minangkabau films with a total duration of 535 minutes. The collected data were formed into a set of data cards, classified based on the criticism speech acts strategies by Nguyen (2005), and analyzed based on Brown and Levinson’s (1987) politeness theory. The data classification in Japanese and Minangkabau was validated through the expert judgment process. The findings indicated that the Japanese and Minangkabau languages employed the same set of criticism speech act strategies but have different tendencies. In Japanese, speakers tend to use indirect strategies as their main criticism speech act strategy by ‘asking/presupposing,’ ‘correction,’ and ‘advice for change.’ Meanwhile, in Minangkabau, speakers tend to use direct strategies by using ‘negative evaluation,’ ‘expression of contradiction,’ and ‘disagreement’ strategies. Regarding the politeness strategy, off-record politeness strategies are more dominantly used among Japanese speakers. In contrast, Minangkabau speakers use bald on-record politeness strategies in criticism speech acts, reflecting their communication culture. The findings of this study provide a deeper understanding of criticism speech act and politeness strategies. The study is expected to contribute to the area of research on intercultural communication and Sociolinguistics.

Published: July 2023

Teacher feedback on students’ writing is critical in developing students’ writing performance which is evident from the abundant research on this area. However, little is known about students’ engagement with teacher feedback in an online EFL writing class. Therefore, applying a survey research design, this study aimed to depict how students engaged in an online EFL writing class. It also examined the students’ perceptions on the teacher feedback provision. This study involved 24 Indonesian students taking Paragraph Writing course offered at a university level. The student’s online EFL writing class activities were observed to know their engagement with teacher feedback on their written work. They were also asked to fill in the questionnaire and interviewed to know their perceptions on the feedback. The results showed that students engaged actively in an online EFL classroom. Besides, teacher feedback was seen as a positive practice that was useful to the process the students undergo in EFL writing, leading to improving their writing performance. The findings imply the need for teachers to use an online class as a new setting for teaching writing and in providing feedback on the students’ drafts. The provision of feedback in the online class should take cognitive and affective dimensions into account to cater to knowledge diversity and lower anxiety.

Bloodstream infections by bacterial pathogens are major cause of morbidity and mortality in developing countries. The aim of this study was to identify the bacterial pathogens causing bloodstream infections in certain areas of Dhaka, Bangladesh and determine their antibiotic susceptibility pattern according to age group.: A total of 6095 blood samples were collected from patients attending at Ad-din Women’s Medical College & Hospital from July 2019 to December 2020. All the blood samples were processed for culture using a BACT/Alert blood culture machine. Further identification & antimicrobial susceptibility tests were performed using standard microbiological procedures. Overall, 10.6% of the cultured blood samples were growth positive. Out of them, Gram-negative bacilli were predominant. Blood stream infection rate is highest among neonates, followed by the age group of 1-15 years, adult patients, with minimum rate observed among the age group of 1 month- 1 Year. was the most frequently isolated among the Growth positive samples, followed by Coagulase negative (CONS), , , species. The most frequently isolated pathogens among Neonates were Coagulase negative Spp, and Spp; whereas was most commonly isolated pathogen among pediatrics and adult age group (p=&#60;.001). However, we observe a decreasing trend in the isolation & the percentage of multi drug resistance amongst spp. in the study period than studies conducted over previous years. A remarkable increase of susceptibility against chloramphenicol & cotrimoxazole has been observed in this study. However, Gram positive organisms show high sensitivity to imepenem, vancomycin and linezolid. This study identified the bacterial pathogens involved with BSI in our hospital among different age groups and their antibiotic susceptibility patterns, so that, healthcare professionals can make proper decisions and provide better care for their patients.

Bloodstream infections (BSIs) may cause significant adverse clinical outcomes among patients affected by Coronavirus disease 2019 (COVID-19). This study was conducted with the objective to characterize the bacterial isolates and their susceptibility pattern and to document the patient outcome as well as skin disinfection measures followed during the venepuncture for the blood collection procedure.All blood cultures received from COVID-19 patients admitted in various COVID care wards and ICUs for a period of two years from June 2020 to May 2022 were included in the study. An automated BacT/ALERT system was used for blood culture. The microbial identification and antimicrobial susceptibility testing were done by standard methods. Patient demographic and treatment details and infection control and prevention practices followed during the blood specimen collection were documented.Out of 172 COVID-19-positive patients blood samples were sent for blood culture with clinical suspicion of sepsis. Out of these, 4.2% were positive. The median age of COVID-19 patients with positive blood cultures was 55 years and about 67% of patients had associated comorbidities. About 31% of patients were admitted to ICUs for their management. The blood culture positivity was documented more among patients with ICU admission, underlying comorbidities, and the presence of an indwelling device. Gram-positive bacterial isolation was more than gram-negative bacteria. About 54% showed clinical improvement at the time of discharge and death was recorded in 19% of patients. There was a lack of strict adherence to the aseptic techniques during the venepuncture for blood collection.The incidence of bloodstream infections documented was low for COVID-19 patients. Hence, empirical antimicrobial agents should be used with care and prompt discontinuation should be done on clinical improvement and based on the microbiology culture report.

However, there was a still a debates whether colonization and/or infection with , increases morbidity and mortality independently of the effect of other risk factors.Aim of the study was to isolate among ICU patients, to detect carbapenem resistant among ICU patients with infections and to determine specific risk factors and outcome of the infections due to CRAB isolates. : A retrospective study was carried out at Vydehi Institute of Medical Sciences and RC in Bangalore, in the ICU department from June 2021 to May 2022.Among all the patients carbapenem resistance was detected more in patients above 60 years of age, males were predominant than females, most of the patients were on ventilation and in sepsis and mortality rate was high with the increased duration of ICU stays. is a highly prevalent microorganism among ICU patients, while its potential to acquire resistance toward commonly used antibiotics represents it as a grave threat to the health care industry. Therefore, signifying the need for its regular monitoring in the health care setups. VAP due to CRAB and excess use of intravascular devices are the most important risk factors for CRAB bacteremia in our ICU. Early implementation of appropriate antimicrobial therapy, particularly in critically ill ICU patients with Carbapenem resistant infections, with two or more co morbidities, can be crucial for survival.
