Telejornalismo contemporâneo no Brasil. Uma análise da cobertura da posse de Jair Bolsonaro e do papel desempenhado pelos telejornais ao informar
Authors: Novais Falcão Luiz Felipe
Published: September 2023

O artigo busca verificar, a partir de reportagens de TV sobre a política, como o universo do poder executivo é tratado por três diferentes emissoras brasileiras. Procura identificar a maneira como o telejornalismo brasileiro se comporta nesse tipo de cobertura e que pistas ele deixa emergir sobre sua autopercepção ao informar. A metodologia é Análise da Materialidade Audiovisual, desenvolvida pelo Núcleo de Jornalismo e Audiovisual/UFJF e que compreende o audiovisual sem a fragmentação (áudio + vídeo + edição). Ela entende a produção de sentido e sua relação com os públicos a partir da experimentação do audiovisual integral. Aplicamos a ficha de análise proposta pelo método nas reportagens que criam narrativas sobre a posse de Jair Bolsonaro nos principais telejornais das três emissoras (JN, RB e JR), cruzamos as informações extraídas para perceber, para além das diferentes linhas editoriais, a ontologia pro-fissional comum as emissoras. O resultado aponta para adaptações do “modo de fazer” telejornalístico e ainda para pistas da relação ruidosa entre o governo e os veículos de comunicação no período.
Radios comunitarias, alternativas y populares en la Provincia de San Luis, Argentina: condiciones, trayectorias y estrategias
Authors: Estrella María Belén
Published: September 2023

Este trabajo busca indagar características y prácticas comunicacionales particulares de radios comunitarias, alternativas y populares en la provincia de San Luis, Argentina, en el período 2010-2020 de acuerdo a la normativa vigente desde la sanción de la Ley 26.522. En San Luis se pueden reconocer tres: La Bulla, Radio Masi y Radio Rebelde, todas ellas surgieron después de la sanción de la ley. La metodología es cualitativa e incluye consulta de registros, relevamientos previos, publicaciones académicas, entrevistas y conversaciones informales con miembros de los medios. Se propone analizar de qué manera cada uno de ellos a través de esas prácticas, buscan - y consiguen o no- construir sostenibilidad. También se considera el tipo de vínculos que establece con otros actores sociales relevantes - el Estado en sus tres niveles y otras organizaciones de la sociedad civil, en un ecosistema de medios marcado por la concentración y centralización que refleja las mismas características del poder político provincial. Las radios comunitarias de San Luis sintieron las repercusiones de los cambios de gestión a nivel nacional, y la parálisis en las políticas de comunicación de la provincia, pero aún así continúan al aire. Sin embargo, la falta de nuevas experiencias de comunicación comunitaria invitan a reflexionar sobre las condiciones sociopolíticas que contribuyen a perpetuar su marginalidad en el sistema infocomunicacional de la provincia.

Correlation of the Neutrophil-to-Lymphocytes Ratio with Serum Urea and Creatinine Levels in Leptospirosis Patients
Authors: Retnoningrum Dwi , Dharmawan Teddy
Published: September 2023

Background: Leptospirosis is a zoonosis that is still a problem in Indonesia. The kidneys are often the target organs in leptospirosis. The outer membrane of Leptospira Sp contains antigenic components and toxins that stimulate the inflammatory process in the kidneys. The neutrophil-to-lymphocyte ratio (NLR) is used as a marker of the inflammatory process, while urea creatinine is a sign of kidney damage. Objective: To prove the correlation between NLR and serum urea and creatinine levels in leptospirosis patients. Methods: This study was carried out retrospectively on the medical records of patients with confirmed leptospirosis by Microscopic Agglutination Test (MAT) at Dr. Kariadi Semarang between January 2020 and July 2022. NLR examination was obtained by dividing the number of neutrophils by the number of lymphocytes in the leukocyte count, urea, and creatinine levels from the patient's medical record. Statistical analysis using the Spearman correlation test, with a significance level of p <0.05. Results: From 33 samples, the median NLR was 10.75 (2.19-47,5), the median urea level was 131.0 mg/dL (15–467 mg/dL) creatinine 2.0 mg/dL (0.7-11.9 mg/dL). The correlation between NLR with urea (p=0.001 and r=0.561) and creatinine (p=0.003 and r=0.501). Increased NLR, urea, and creatinine were found in leptospirosis patients. Conclusion: There is a moderate positive correlation between NLR and urea and creatinine. An increase in NLR is a sign of an inflammatory process from leptospirosis. An increase in NLR correlates with an increase in urea and creatinine

Published: September 2023

Background: Tuberculosis (TB) is a global health problem. It poses a significant burden worldwide, requiring urgent control measures and research for effective reduction especially in Indonesia.Objective: Investigating the effects of literacy, population density, and access to improved sanitation on TB incidence can provide insights into the relationship between these factors.Methods: This study was conducted in Jakarta, Indonesia from June to July 2023, using secondary data from 2005 to 2021. It employed a quantitative cross-sectional design to examine the relationship between variables. Data were collected from the ASEAN database and analyzed using descriptive and path analysis techniques to determine variable effects and significance. The study found that the incidence of tuberculosis in Indonesia initially decreased from 2005 to 2020 but significantly increased in 2021.Results: Population density, adult literacy rate, and access to improved sanitation all showed positive trends. Significant direct effects were observed among most variables, and indirect effects of population density on tuberculosis incidence were also identified through literacy and sanitation. The final model showed that higher population density correlated with increased access to sanitation and literacy rate, while access to improved sanitation was associated with reduced tuberculosis incidence. Overall, the model had a very good fit based on the indicators.Conclusion: Priority investments in sanitation infrastructure, especially in densely populated areas, along with improved access to sanitation facilities, combined with targeted health education campaigns and collaboration across defense, health, and education sectors, are recommended to enhance tuberculosis prevention and control

Published: September 2023

The aim of this study is to construct an artificial neural network (ANN) based on bioinformatic analysis to enable early diagnosis of peri-implantitis (PI). PI-related datasets were retrieved from the Gene Expression Omnibus database. Differentially expressed genes (DEGs) and functional enrichment analyses were performed between PI and the control group. Furthermore, the infiltration of 22 immune cells in PI was analyzed using CIBERSORT. Hub genes were identified with random forest (RF) classification. The ANN model was then constructed for early diagnosis of PI. A total of 1,380 DEGs were identified. Enrichment analysis revealed the involvement of neutrophil-mediated immunity and the NF-kappa B signaling pathway in PI. Additionally, higher proportion of naive B cells, activated memory CD4 T cells, activated NK cells, M0 macrophages, M1 macrophages, and neutrophils were observed in the soft tissues surrounding PI. From the RF analysis, 13 hub genes (ST6GALNAC4, MTMR11, SKAP2, AKR1B1, PTGS2, CHP2, CPEB2, SYT17, GRIP1, IL10, RAB8B, ABHD5, and IGSF6) were selected. Subsequently, the ANN model for early diagnosis of PI was constructed with high performance. We identified 13 hub genes and developed an ANN model that accurately enables early diagnosis of PI.
Domestication of Russian Cuisine in the United States: Wanda L Frolov’s Katish: Our Russian Cook (1947)
Authors: Razor Sasha
Published: September 2023

This article examines Wanda L Frolov’s cookbook, Katish: Our Russian Cook (1947) as a transitional text that navigates the food diplomacy of World War II and the Cold War “Red Scare.” The book narrates the story of two women from different parts of the world and walks of life – an American widow and a refugee widow from Russia – who lived together in Southern California during Prohibition. The plot is presented through the point-of-view of one of the characters, Sis, as she recounts her childhood memories, while recipes come in clusters triggered by specific vignettes. Using irony, exoticisms, and literary and cultural allusions, the cookbook embodies the journey of the Russian character from her home country to the United States through American recipes. In Katish: Our Russian Cook, Frolov created an original character who asserts herself in the female space of the kitchen while adjusting to a new country. This adjustment is reflected in the hybrid Russian–American menu, which represents a radical departure from the three decades worth of auto-ethnographic cookbooks produced by the white émigrés in the United States. Frolov’s mode of representation of the Russian identity is fused with consumer potential as a positive force, while the child’s eye view of the story obfuscates the refugee trauma narrative. Released before the advent of television cooking shows and food editor conferences, Katish: Our Russian Cook mapped the local Los Angeles culinary scene in the 1920s and contributed to the development of the culinary memoir writing genre. Published first during the Cold War and republished by Ruth Reichl in 2001, it serves as a pertinent example of American integration and domestication of Russianness.
Show Me the Money: Tracking Consumer Spending with Daily Card Transaction Data During the Pandemic
Authors: Cevik Serhan
Published: September 2023

The COVID-19 pandemic has been an unprecedented shock to economic activity with abrupt and unexpected changes in household consumption behavior. This paper investigates how the spread of the pandemic and government interventions have affected consumer spending using daily card transaction data in the Baltics. The analysis shows significant effects on the amount and composition of debit and credit card transactions. First, the number of new COVID-19 infections or deaths has a strongly negative effect. Second, while public health measures designed to contain the spread of the pandemic has a negative effect, economic support measures designed to assist businesses and households have a stimulative effect. Third, there is heterogeneity across spending categories, but the drop is mostly concentrated in sectors that are restricted by lockdowns and the risk of infection. Fourth, the impact of government interventions, especially in terms of stimulating consumer spending, appears to be more pronounced on goods than services.
Assessment of GNSS observations and positioning performance from non-flagship Android smartphones

Published: September 2023

Android smartphone has gained attention in precise positioning applications since it can collect raw observable GNSS (Global Navigation Satellite System) data. Some studies have reported that the positioning accuracy may reach the sub-decimeter level. However, these studies mostly rely on a flagship Android smartphone that is made with better internal hardware, while the use of a non-flagship Android smartphone is not reported for this field. In this study, therefore, we explore non-flagship Android smartphones for positioning applications. We assessed the observable data quality and positioning performance of two non-flagship Android GNSS smartphones of a Samsung M21 and a Redmi Note 7. The data quality assessment includes satellite tracking and carrier-to-noise density ratio analysis. Also, the positioning performance was assessed for Single Point Positioning (SPP) and relative positioning methods in static and open-sky conditions. In addition, the residual properties of GNSS measurements were also evaluated. The results were further compared to the high-grade GNSS device. We found that the observable pseudorange and carrier phase measurements from Android smartphones were about 70 % and 36 % of what high-grade GNSS obtained. Furthermore, within a span of 1 h of observations, a considerable amount of cycle slips, amounting to as many as 518 instances, were noted in the observations from Android GNSS devices. While for the carrier-to-noise density ratio in Android smartphones, it was estimated to be about 15 dB-Hz lower than in high-grade GNSS devices. The spread of the residuals for pseudorange and carrier phase from Android smartphones was estimated to be about ±15 and ±6 m, respectively. The 3D positioning error for SPP was estimated to be about 4.7 m, with a position spread reaching tens of meters. At the same time, the 3D positioning error was calculated to be 4.6 m with the estimated standard error at the centimeter level when using the relative positioning method. To improve the positioning performance, applying a C/N0mask to the observations become the best solution. The 3D positioning error for the relative positioning method reduces to 2.7 m when applying a C/N0mask of 30 dB-Hz. The observable data quality of non-flagship Android GNSS devices possibly causes relatively poor performance of positioning applications.

Authors: Guo Ran , Li Xuan , Niu Weilong , Feng Jianbo
Published: September 2023

Electrohydrodynamic-jet (E-jet) printing is an on-demand additive manufacturing method that allows various functional materials to be directly deposited on the target substrate. Many theoretical and experimental results indicate that E-jet has scale effect, and reducing the inner diameter of the nozzle can effectively improve printing resolution. Herein, a method for fabricating SU-8 polymer micro/nanoscale nozzle by oxygen plasma assisted room temperature bonding was proposed. It can prevent channel deformation and blockage caused by excessive bonding temperature. The surface modification parameters of silicon nano-mold were optimized, the influence of hot embossing parameters on the replication precision of nano patterns was investigated, the effect of UV lithography parameters on the micro and nanochannel was analyzed, the relationship between the oxygen plasma treatment parameters on the contact angle of SU-8 was revealed, the influence of bonding pressure on the morphology of the nanochannel was discussed, and the bonding principle at room temperature was deeply analyzed. This method can fabricate SU-8 polymer micro/nanoscale nozzle with low cost and high precision, and provide a new idea for the realization of room temperature bonding to manufacture SU-8 polymer nozzle.

Published: September 2023

Engineered cementitious composites (ECC) exhibit behaviors of multiple cracking and strain-hardening compared to ordinary concrete. However, the use of ultrafine silica sand (S) to produce ECC results in increased cost and environmental overload. This study was to develop an eco-friendly and cheaper ECC by incorporating different replacement ratios of industrial byproduct molybdenum tailings (MT). The mechanical properties of ECC with MT were evaluated. Based on industrial computer technology, nuclear magnetic resonance, and scanning electron microscope techniques, the three-dimensional spatial distribution and fluid distribution of pores and the microstructure of the ECC were investigated, respectively. The mechanical properties of stirrup-confined ECC stub columns were also investigated. Results indicated that the ECC incorporating 25% MT exhibited the best mechanical properties, in which the tensile strength (f
t) increased by 32.16% and exhibited well strain-hardening behaviors. Under a 25% MT replacement ratio, ECC had the lowest porosity and good interfacial transition zone, and bonding interface between polyvinyl alcohol (PVA) fiber (PF) and matrix. Moreover, the stirrup-confined ECC stub column with 25% MT can ensure better both the peak stress (f
cc) and peak strain (ε
cc). The assessment of environmental impact and cost further indicated that the incorporation of MT to prepare ECC is a promising method.
La variación ter que, haber (de/que) y deber y sus valores modales en el gallego oral contemporáneo: una aproximación basada en el uso
Authors: Amarelo Daniel
Published: September 2023

Desde un enfoque basado en el uso y en los estudios sobre gramaticalización, este trabajo pretende estudiar sincrónicamente la variación entre los verbos modales ter que, haber (de/que) y deber (de) en gallego. Analizaremos cuantitativamente un corpus de más de trescientos enunciados reales de carácter oral extraídos del CORILGA (Corpus Oral Informatizado da Lingua Galega) e interpretaremos los resultados de acuerdo con aquellos factores significativos en la selección – registro, voz, polaridad y valor semántico. Ya que no existen análisis variacionistas y cuantitativos de esta cuestión en gallego, esta aproximación pretende abrir el campo de investigación en dicha dirección. En definitiva, postulamos cuál es su distribución aproximada en términos modales y qué cambios podrían estar en marcha, en comparación con otras variedades lingüísticas y a la luz de aproximaciones previas a este tema. La contribución más relevante se halla en la ampliación de usos de ter que a territorios epistémicos (0a) y en la especialización de haber (de) (0b) como forma epistémica fuerte con poca evidencialidad.

(0a) “pois ten que estar deprimidísima, supoño”

Context-specific use and ideology: perception of appropriate domains for dar + gerund
Authors: Guerra Kathleen S.
Published: September 2023

This investigation explores the perception and use of dar ‘give’ + gerund, i.e., dame pasando ‘pass me’, as a request in Ecuadorian Andean Spanish. Previous research has focused on origins and uses of dar + gerund, often classifying it as an attenuated request form that arose, in part, from sustained contact with Ecuadorian Kichwa. This paper demonstrates that a simple definition of politeness insufficiently captures the requester’s complex calculation of social relationship, perceived imposition, indirectness and politeness when making a request with dar + gerund. Furthermore, dar + gerund tends to be perceived as most appropriate in equal social/functional relationships, breaking with previous research that positions more attenuated requests with deference and formality. By examining the perception of appropriate use through an online questionnaire, observations and sociolinguistic interviews, this investigation shows how this dialectal construction encodes a range of social meaning in a particular context.

Koźlenia, D, and Domaradzki, J. Postsubmaximal isometric full squat jump potentiation in trained men. J Strength Cond Res 38(3): 459–464, 2024—This study investigated the effects of postsubmaximal isometric full squats on jump height (JH). The study included 45 men aged 20–27 years with at least 6 years of resistance training experience that had been continuous for at least 2 years and a minimum relative strength of 120% of body mass in the full-back squat. They were randomly divided into an experimental group (EG) and a control group (CG). After a standard warm-up, subjects performed a countermovement jump (CMJ) to ascertain a baseline value. A conditioning activity (CA) introduced in the EG involved three 4-second sets of a high bar isometric full-back squat at 70% repetition maximum, with a 1-minute break. Five CMJs were performed in the following 9 minutes. Statistical significance was set at α = 0.05. A 2-way analysis of covariance (ANCOVA) (group-time), with baseline CMJ as a covariable, revealed statistically significant differences between groups ( p < 0.0001). The Bonferroni post hoc tests revealed higher results in the EG at the third, fifth, seventh, and ninth minutes ( p < 0.05). A 1-way repeated-measures analysis of variance (ANOVA) showed that time was statistically significant within groups ( p < 0.0001). The post hoc tests indicated JH improvement after 3 minutes compared with the baseline, and the trend persisted in the following 6 minutes ( p < 0.05) in the EG. The postactivation performance enhancement (PAPE) protocol based on a submaximal isometric full squat enhanced JH in the third minute after CA, which persisted for at least 6 minutes. These results indicate a requirement to evoke performance enhancement in response to an isometric CA.

Abstract: On the road network in the Republic of Serbia, is establish monitoring of parameters at certain points of road network for the needs of the organization that deals with road maintenance and implementation of PBMC (Performance based Maintenance Contract), which has a need for mass collection of data from roads and road facilities. One of the parameter is the temperature, whose measurement on the bridge structure over the Danube near Kovin/Smederevo will be the primary focus of this paper. New technology Lo Ra sensors were used to collect temperature data. This type of sensor has low energy consumption so it does not require a specially implemented power supply. The service life of such sensors is estimated at a minimum of 5 years in environmental conditions. Communication is achieved using Lo Ra WAN technology that requires an access communication point at a distance of up to 8 km from the sensor with a bandwidth capacity of 3 kbps to 50 kbps. This sensor allows the measurement and collection of temperature data as a primary function and is also able to measure local acceleration in three axes on the structural element on which it is mounted. This way of collecting data using wireless sensors with low power consumption significantly improves efficiency and economy in the field of road maintenance and monitoring.

In malaria-endemic regions, infection with the malaria parasite Plasmodium during pregnancy has been identified as a key modifiable factor in preterm birth, the delivery of low-birthweight infants, and stillbirth. Compared with their nonpregnant peers, pregnant persons are at higher risk for malaria infection. Malaria infection can occur at any time during pregnancy, with negative effects for the pregnant person and the fetus, depending on the trimester in which the infection is contracted. Pregnant patients who are younger, in their first or second pregnancy, and those coinfected with human immunodeficiency virus are at increased risk for malaria. Common infection prevention measures during pregnancy include the use of insecticide-treated bed nets and the use of intermittent preventive treatment with monthly doses of antimalarials, beginning in the second trimester in pregnant patients in endemic areas. In all trimesters, artemisinin-combination therapies are the first-line treatment for uncomplicated falciparum malaria, similar to treatment in nonpregnant adults. The World Health Organization recently revised its recommendations, now listing the specific medication artemether-lumefantrine as first-line treatment for uncomplicated malaria in the first trimester. While strong prevention and detection methods exist, use of these techniques remains below global targets. Ongoing work on approaches to treatment and prevention of malaria during pregnancy remains at the forefront of global maternal child health research.

The diagnosis of acute proctitis requires understanding who is at risk, being aware of symptoms, and leveraging a thorough sexual history with appropriate risk stratification to make the diagnosis. Cases have been concentrated in adolescents (ages 15–19 years), young adults (ages 20–24 years), men and transgender women who have sex with men, and those with a history of human immunodeficiency virus infection. Black adolescents experience a disproportionately high number of cases of proctitis due to an intersection of concentrated cases in sexual networks and delayed screening/diagnosis due to health care access barriers. Signs and symptoms include purulent discharge, bleeding, pain, tenesmus, pruritus, diarrhea or constipation, weight loss, or fever. Multisite sexually transmitted infection testing should be offered based on risk stratification (eg, history of condomless anal sex, oral intercourse, number of sex partners). Further management includes promotion of barrier protection and preexposure prophylaxis, routine surveillance, partner notification, and routine access to preventive immunizations.

Transmissive viral proventriculitis (TVP) is a new avian disease, the etiology and pathogenesis and diagnostics of which remain unidentified, being therefore a subject of an active ongoing discussion among researchers and veterinary doctors. Cases of the disease have been reported and registered in many countries of the world. On poultry farms of Ukraine, this disease started to be diagnosed in 2019, according to the characteristic pathognomic changes. The article presents the results of pathoanatomical, histological and electronic-microscopical studies of the glandular part of the stomach of 62 ill broiler chickens aged 24-28 days and 7 clinical healthy broiler chickens of the same age. The samples of the proventriculus from the infected and clinically healthy chickens were fixated in 10% aqueous solution of neutral formalin and in 1.5% solution of glutaraldehyde in 0.2 molar cacodylate buffer (рН 7.2). Pathoanatomic necropsy of the infected broiler chickens revealed overall anemia, decrease in the volume of the spleen, thymus and fecal sac. In the glandular part of the stomach, the wall was slightly thickened, non-homogenously stained on the section, the mucous membrane being swollen, covered by dense whitish mucous. According to the histological study, the proventriculus of the broiler chickens had lymphocytic necrotizing proventriculitis. In the tubular-alveolar structures of the mucous membrane, there prevailed alteration of the secretory epithelium, with its transformation into ductal epithelium, combined with lymphocytic infiltration of the interstitium. Intensive necrosis of most glandular (oxynticopeptic) cells was accompanied by their exfoliation from the basal membrane of the secretory parts, with desquamated cells accumulating in enlarged lumens of alveoli and excretory ducts. Further, necrotized oxynticopeptic cells in the tubular-alveolar glands were actively replaced by cylindrical ductal cells, and also their hyperplasia and hypertrophy occurred. Diffusive and multifocal interalveolar round-cell infiltrates were mostly presented by lymphocytes, among which there occurred plasmocytes, macrophages, and heterophils. Ultrastructural studies of secretory cells revealed presence of pathogen virions in nucleus and cytoplasm. Based on the morphological changes in the birds’ proventriculus, we diagnosed transmissive viral proventriculitis, which had not been recorded in Ukraine before.

Diseases of the mammary gland in cows are of multi-factor nature, which significantly complicates their control and treatment. One of the factors influencing development of mastitis is bacterial microflora. Because of limited use of antibiotics, development of novel alternative antmicrobial drugs is of great relevance. Therefore, the objective of the study was identifying the effect of an ethyl-thiosulfanilate-based liposomal drug on the hematological and biochemical parameters of blood of the cows suffering catarrhal mastitis. The animals were three times intramuscularly injected with the liposomal drug in the dose of 0.04 mL/kg of body weight. Blood from the cows was taken from the jugular vein on the day prior to administration of the drug, and also on the 3rd and 7th days after its application. During the bacterial study of the secretion of udder of sick cows, we collected 51 bacterial isolates, in which dominated Staphylococcus aureus (27.5%) and Streptococcus spp. (21.6%). In blood of the sick cows, we found higher number of leukocytes, increases in the concentrations of circulating immune complexes, lipid hydroperoxides, and ketone derivatives of oxidative modification of proteins. At the same time, we observed decreases in the number of lymphocytes and concentration of protein and the bactericidal activity of blood serum. Administration of the complex liposomal drug had a normalizing effect on the analyzed parameters of the cows. This was evidenced by 9.4% decrease in the total number of leukocytes, 18.5% decrease in the content of circulating immune complexes, 9.3% increase in lymphocytes, and 13.6% increase in the level of total protein. In the sick cows, the drug enhanced the bactericidal (by 35.4%) and lysozymic (by 36.3%) activities of blood serum, glutathione peroxidase activity, and increased the content of reduced glutathione. On the seventh day after injecting the drug into blood of the cows, we saw decrease in the level of intermediate and end products of lipid peroxidation and derivatives of oxidative modification of proteins. Therefore, the complex ethyl-thiosulfanilate-based liposomal drug promoted reduction of metabolic homeostasis of the organism, had positive effect on the activity of natural defense mechanisms in the organism and can be recommended for the treatment of cows with catarrhal mastitis.
