Abstract This article investigates the institutional grammar of data protection and privacy in Brazil. By adopting the analytical lens of the Institutional Grammar Tool (IGT), it deconstructs the institutional statements within the regulatory decrees of the General Data Protection Law (LGPD) in Brazilian states, classifying the different grammatical elements that inform state-level strategies for data protection and governance. It examines how the concepts of data protection, data governance, and privacy are formulated, as well as the institutional construction of data protection in Brazil. By taking an empirical approach, it aims to address the following questions: What is the institutional design of the strategies adopted by Brazilian states, within the federation, to protect personal data and citizens’ privacy? What are the implications of this design on how effective data protection is in Brazil? The article concludes that the data protection strategies formulated by the states lean more toward bureaucratic control of data processing than the actual realization of emerging citizenship rights.

Abstract This article proposes an indicator that describes each Brazilian municipality’s learning level of its elementary school students, as well as learning inequalities among groups of students defined by socioeconomic status, race, and sex. This indicator is necessary because learning inequalities are growing and are not observed by the country’s main educational indicator, the Basic Education Development Index (IDEB). This study initially conceptualizes justice in education, positioning itself in the debate on theories of justice. Then, it presents the methodological aspects of the indicator and the results obtained. The main finding is that the subjects and school grades in which the highest number of municipalities increased their learning levels are also those in which there was a strong increase in inequalities. municipalitys municipality s status race sex countrys country IDEB.

Analysis of variance (ANOVA)-simultaneous component analysis (ASCA) is a method of choice for factorial design studies of environmental impacts on plant metabolomes and can be used to quantitatively carry out this comparative analysis. The impacts of seven mixture design extractor systems made up of ethanol, dichloromethane, and hexane and their 1:1 binary and 1:1:1 ternary solvents for several replicate experiments (n = 3, 4, 5) were assessed using ASCA models determined from Fourier-transform infrared (FTIR), near-infrared (NIR), and UV-Vis spectroscopic measurements on yerba mate leaf extracts. This analysis considered two-factor effects: secondary sexual dimorphism (male and female plants) and cultivation systems (monoculture and agroforestry), as well as their interaction effect. The three binary solvents were found to be more efficient extractor systems for all four detectors as they found 83 main and interaction effects significant at or above the 95% confidence level compared with only 47 for the pure solvent extracts. Binary solvent extracts resulted in averages between 44.04 and 86.61% for the ASCA total effect variances compared with 40.62 to 71.07% for pure extractors. Of the 60 significant effects found for experiments with 5 repetitions 53 or 88% were obtained with only triplicate determinations. The choice of spectroscopic technique and solvent system have large impacts on metabolomic analysis results.

Seeking a viable alternative to fossil fuels as the primary energy source, bioethanol has emerged as a promising second-generation fuel derived from lignocellulosic biomass. With Brazil ranking pineapple as the third most produced fruit in temporary crops, this study aims to assess the impact of chemical pretreatment techniques, specifically organosolv and diluted acid, on the residual biomass of Pérola pineapple peel to enhance bioethanol production. Employing an experimental design that incorporates temperature, reaction time, and varying concentrations of organic solvent, the study examines their effects on the susceptibility of the substrate to saccharification for future bioethanol generation. Factors such as alphacellulose, hemicellulose, and lignin were evaluated in triplicate and subjected to statistical analysis using the Tukey test with a confidence level of 95%. Upon application of the pretreatment methods, it was observed that the organosolv solvent approach (utilizing water and ethanol) with sulfuric acid exhibited superior sugar conversion, yielding the highest concentration of xylose at 9.13 g L-1. Additionally, the pretreated biomass contained 1.38 g L 1 of cellobiose, 3.11 g L-1 of arabinose, and 3.76 g L-1 of glucose. This technique demonstrates promising potential for obtaining fermentable sugars crucial for bioethanol production. source secondgeneration second generation crops techniques production temperature time alphacellulose hemicellulose 95 95% methods utilizing ethanol conversion 913 9 13 9.1 L1.

ABSTRACT Purpose: This study investigated the relationship between blood pressure and intraocular pressure in treatmentnaive, non-glaucoma patients with different blood pressure statuses, focusing on the 24-h ocular volume and nocturnal blood pressure decline. Methods: Treatment-naive, non-glaucoma patients undergoing hypertension evaluation were enrolled as study participants. Simultaneous 24-h ambulatory blood pressure measurement and 24-h ocular volume recording with a contact lens sensor. We also compared ocular volume curve parameters between normotensive and hypertensive patients, as well as between those with and without nocturnal blood pressure decline. Results: A total of 21 patients, including 7 normotensive and 14 treatment-naive hypertensive individuals, were included in the study. of them, 11 were dippers and 10 were non-dippers. No significant difference in the 24-h ocular volume slope was observed between the hypertensive and normotensive patients (p=0.284). However, dippers had a significantly higher 24-h ocular volume slope (p=0.004) and nocturnal contact lens sensor output (p=0.041) than non-dippers. Conclusion: Nocturnal blood pressure decline, rather than the blood pressure level, is associated with the increased 24-h ocular volume slope and nocturnal ocular volume. Further studies are required to determine whether the acceleration of glaucoma progression in dippers is primarily due to low blood pressure, high intraocular pressure, or a combination of both.

Even though ammonia is a natural component of aquatic environments, elevated concentrations indicate pollution and environmental degradation. Consequently, efficient analytical methods for monitoring ammonia levels are crucial for preserving water quality. Voltammetry offers a sustainable approach for NH3 quantification, combining good analytical performance with low sample and reagent consumption, minimizing waste generation. However, despite these advantages, the voltammetric determination of ammonia remains relatively unexplored. Therefore, this study investigated the electrochemical behavior of NH3 in alkaline solutions using a non-modified Pt electrode and evaluated the performance of differential pulse voltammetry (DPV) and square wave voltammetry (SWV) for NH3 determination. DPV provided superior performance, with limits of detection and quantification of 0.79 µmol L-1 (0.011 ppmN) and 2.6 µmol L-1 (0.036 ppmN), respectively, which comply with the maximum allowable ammonia concentration in natural waters according to Brazilian and European regulations. The voltammetric method successfully quantified ammonia in tap and river water samples, providing results concordant with the established Berthelot spectrophotometric method, at a 95% confidence level. Additionally, it is simple and fully accessible to non-electrochemist since no sophisticated procedures for electrode modification are needed. Finally, the high analytical performance of the proposed method makes it valuable for pollution monitoring in aquatic environments. environments degradation Consequently quality NH consumption generation However advantages unexplored Therefore nonmodified non modified (DPV SWV (SWV 079 0 79 0.7 L1 L 1 L- 0.011 0011 011 (0.01 ppmN 26 2 6 2. 0.036 0036 036 (0.03 ppmN, , respectively regulations samples 95 level Additionally nonelectrochemist electrochemist needed Finally 07 7 0. 0.01 001 01 (0.0 0.03 003 03 9 0.0 00 (0.

ABSTRACT Purpose: The epithelial–mesenchymal transition of human lens epithelial cells plays a role in posterior capsule opacification, a fibrotic process that leads to a common type of cataract. Hyaluronic acid has been implicated in this fibrosis. Studies have investigated the role of transforming growth factor (TGF)-β2 in epithelial–mesenchymal transition. However, the role of TGF-β2 in hyaluronic acid-mediated fibrosis of lens epithelial cell remains unknown. We here examined the role of TGF-β2 in the hyaluronic acid-mediated epithelial–mesenchymal transition of lens epithelial cells. Methods: Cultured human lens epithelial cells (HLEB3) were infected with CD44-siRNA by using the Lipofectamine 3000 transfection reagent. The CCK-8 kit was used to measure cell viability, and the scratch assay was used to determine cell migration. Cell oxidative stress was analyzed in a dichloro-dihydro-fluorescein diacetate assay and by using a flow cytometer. The TGF-β2 level in HLEB3 cells was examined through immunohistochemical staining. The TGF-β2 protein level was determined through western blotting. mRNA expression levels were determined through quantitative real-time polymerase chain reaction. Results: Treatment with hyaluronic acid (1.0 μM, 24 h) increased the epithelial–mesenchymal transition of HLEB3 cells. The increase in TGF-β2 levels corresponded to an increase in CD44 levels in the culture medium. However, blocking the CD44 function significantly reduced the TGF-β2-mediated epithelial–mesenchymal transition response of HLEB3 cells. Conclusions: Our study showed that both CD44 and TGF-β2 are critical contributors to the hyaluronic acid-mediated epithelial-mesenchymal transition of lens epithelial cells, and that TGF-β2 in epithelial-mesenchymal transition is regulated by CD44. These results suggest that CD44 could be used as a target for preventing hyaluronic acid-induced posterior capsule opacification. Our findings suggest that CD44/TGF-β2 is crucial for the hyaluronic acid-induced epithelial-mesenchymal transition of lens epithelial cells.

RESUMO Objetivo: Examinar a associação entre vitimização por bullying e comportamentos de risco à saúde em adolescentes. Métodos: Uma amostra representativa de 1.020 adolescentes participou do estudo. As variáveis bullying, comportamentos de risco à saúde (tabaco, drogas, álcool, comportamento sedentário, uso de smartphone, nível de atividade física, sono) e situação econômica foram avaliadas por meio de questionários autorreportados. Razões de chance com intervalos de confiança de 95% (IC95%) foram obtidas por meio de regressão logística binária e regressão logística ordinal, bruta e ajustada (p<0,05). Resultados: As vítimas de bullying apresentaram maior probabilidade de fumar (OR 1,75; IC95% 1,28–2,40), consumir álcool (OR 1,43; IC95% 1,05–1,94), ter pior qualidade de sono (OR 1,94; IC95% 1,28–2,91) e apresentar mais comportamento sedentário (OR 1,43; IC95% 1,08–1,89) do que aqueles que não sofreram bullying. No entanto, as vítimas eram mais propensas a ter níveis elevados de atividade física do que os seus pares não vítimas de bullying (OR 1,66; IC95% 1,22–2,27). Conclusões: A vitimização por bullying esteve associada ao aumento da predisposição para a adoção de comportamentos de risco à saúde. Curiosamente, as vítimas também eram mais propensas a participar de atividades físicas.

ABSTRACT Objective: The aim of this study was to examine the association between bullying victimization and health risk behaviors in adolescents. Methods: A representative sample of 1020 adolescents participated in the study. The variables such as bullying, health risk behaviors (tobacco, drugs, alcohol, sedentary behavior, smartphone use, level of physical activity, and sleep), and economic status were assessed using self-reported questionnaires. Odds ratios with 95% confidence intervals (95%CI) were obtained using binary logistic regression and ordinal, gross, and adjusted logistic regression (p<0.05). Results: Victims of bullying were more likely to smoke (OR 1.75; 95%CI 1.28–2.40), consume alcohol (OR1.43; 95%CI 1.05–1.94), have worse sleep quality (OR 1.94; 95%CI 1.28–2.91), and more sedentary behavior (OR 1.43; 95%CI 1.08–1.89) than those who were not bullied. However, victims were more likely to have high levels of physical activity than their non-bullied peers (OR 1.66; 95%CI 1.22–2.27). Conclusions: Bullying victimization was associated with an increased predisposition for the adoption of health risk behaviors. Interestingly, victims were also more prone to participate in physical activity.

RESUMO Objetivo: Analisar a associação entre a participação em exercícios físicos relacionados ao fitness (EFRF) e a insatisfação com a imagem corporal (IIC) em adolescentes e avaliar a interação entre os exercícios físicos e o estado nutricional nesta associação. Métodos: Estudo transversal realizado em 2015 com 799 adolescentes (10 a 16 anos) de 14 escolas públicas de Curitiba (PR), Brasil. A IIC foi avaliada por meio do Body Shape Questionnaire e da Escala de Silhuetas. A participação em EFRF foi avaliada pelo Questionário de Atividade Física para Adolescentes e classificada em “não pratica”, “pratica ≤300 minutos/semana” e “pratica >300 minutos/semana”. As regressões de Poisson e logística multinomial, ajustadas por sexo, maturação sexual e estado nutricional, analisaram a associação entre EFRF e IIC. Resultados: A prevalência de IIC foi de 28,3%; 52,4% dos adolescentes queriam reduzir a silhueta e 48,7% não praticavam a EFRF. Adolescentes que praticavam EFRF >300 minutos/semana tiveram prevalência 28% maior para algum nível de IIC (razão de prevalência — RP 1,28; intervalo de confiança de 95% — IC95% 1,08–1,52) e chance 46% menor de querer reduzir silhuetas (OR 0,54; 95IC% 0,35–0,82), comparados aos não praticantes. Não houve interação entre os EFRF e o estado nutricional na associação com IIC. Conclusões: Os adolescentes que praticam EFRF >300 minutos/semana estão mais propensos a apresentar algum nível de IIC e têm menores chances de reportar o desejo de aumentar silhuetas, independentemente do estado nutricional.

ABSTRACT Objective: The aim of this study was to analyze the association between participation in fitness-related exercises (FRE) and body image dissatisfaction (BID) in adolescents and evaluate the interaction between physical exercise and nutritional status in this association. Methods: A cross-sectional study was conducted in 2015 involving 799 adolescents (10–16 years old) from 14 public schools in Curitiba (PR), Brazil. BID was assessed using the Body Shape Questionnaire and the Silhouette Scale. The FRE was classified as “does not practice,” “practices ≤300 min/week,” and “practices >300 min/week” by the Physical Activity Questionnaire for Adolescents. Poisson and multinomial logistic regressions, adjusted for sex, sexual maturation, and nutritional status analyzed the association of FRE and BID. Results: The BID prevalence was 28.3%; 52.4% of the adolescents wanted to reduce their silhouettes; and 48.7% did not practice FRE. Adolescents who practiced FRE >300 min/week had a 28% higher prevalence for some level of BID (PR 1.28; 95%CI 1.08–1.52) and a 46% lower chance of wanting to reduce silhouettes (OR 0.54; 95%CI 0.35–0.82), compared to nonpractitioners. There was no interaction between FRE and nutritional status in association with BID.

A new alkaloid, named brazoide Ε (6), three known steroids (campesterol, β-sitosterol, stigmasterol), two glucosides (3-O-β-D-glucopyranosylsitosterol and 3-O-β-D-glucopyranosyl stigmasterol) and sucrose were isolated from the leaves and stems of Justicia wasshauseniana. Their structures were characterized using high-resolution electrospray ionization mass spectrometry (HRESIMS), nuclear magnetic resonance (1D and 2D NMR), and infrared (IR) spectroscopy. To reinforce the structural proposal, an acetylated derivative (6a) was obtained and its data compared to 6. Moreover, circular dichroism spectroscopy (CD) analysis was performed to determine the absolute stereochemistry, time-dependent density functional theory (TD-DFT) at the wB97X-D/def2-TZVP level, adopting functionals M06-2X and wB97X-D and base aug-cc-pVDZ, was employed to confirm the CD analysis. alkaloid 6, 6 , (6) campesterol, campesterol (campesterol βsitosterol, βsitosterol β sitosterol, sitosterol β-sitosterol stigmasterol, stigmasterol 3OβDglucopyranosylsitosterol OβDglucopyranosylsitosterol 3 O D glucopyranosylsitosterol 3OβDglucopyranosyl OβDglucopyranosyl glucopyranosyl wasshauseniana highresolution high resolution HRESIMS, HRESIMS (HRESIMS) 1D NMR, NMR NMR) IR (IR proposal 6a a (6a Moreover (CD stereochemistry timedependent time dependent TDDFT TD DFT (TD-DFT wB97XD/def2TZVP wB97XDdef2TZVP wBXDdefTZVP wB97X D/def2 TZVP def2 wB X def level M062X MX M06 2X M wB97XD wBXD augccpVDZ, augccpVDZ aug cc pVDZ, pVDZ aug-cc-pVDZ (6 (HRESIMS def2TZVP XD XDdef wBX Ddef2 Ddef D/def M0 ( defTZVP

Asphaltenes are complex molecules with a tendency to aggregate. This property can be an issue for the oil industry due to CO2 reinjection into reservoirs to mitigate these gas emissions. The present theoretical study aimed to study the CO2 interaction with no-substitute and substituted coronene as an asphaltene model compound at CAM-B3LYP-D3/6-311G(d,p) level. The electronic properties were evaluated using harmonic oscillator model of aromaticity (HOMA), quantum theory of atoms in molecules (QTAIM), and reduced density gradient (RDG) methods. The results showed that the coronene’s functionalization by a sulfur atom changes the coronene’s electronic structure. However, functionalization does not change the type of interactions between the monomers, as they remain predominantly van der Waals interactions. CO2 interaction with substituted coronene barely changed due to the presence of sulfur atoms. However, in dimers, the position of the heteroatom directly influences the interaction with CO2, although it is insufficient to change the interaction’s magnitude. For this reason, our results indicate that the sulfur heteroatom in asphaltenes should be addressed. However, new studies must be conducted by increasing the number of substituents, CO2 numbers, and the model size. aggregate CO emissions nosubstitute no substitute CAMB3LYPD3/6311Gd,p CAMB3LYPD36311Gdp CAMBLYPDGdp CAM B3LYP D3/6 311G d,p D3 6 d p B LYP D G CAM-B3LYP-D3/6-311G(d,p level HOMA, HOMA , (HOMA) QTAIM, QTAIM (QTAIM) RDG (RDG methods coronenes s structure However monomers dimers magnitude reason addressed substituents numbers size CAMB3LYPD3 6311Gd CAMB LYPD Gd Gdp BLYP D36 D3/ dp (HOMA (QTAIM CAMBLYPD CAMB3LYPD

RESUMO: Objetivou-se avaliar a eficácia do sulfato de magnésio e cetamina em reduzir o requerimento de propofol, remifentanil e o resgate analgésico pós-operatório de gatas submetidas à ovariohisterectomia eletiva. Trinta gatas foram pré-medicadas com acepromazina (0,05 mg/kg) e morfina (0,3 mg/kg), intramuscular, e induzidas a inconsciência com propofol para intubação orotraqueal. As infusões contínuas (IC) de propofol e remifentanil foram iniciadas e os animais foram aleatoriamente alocados em três grupos: grupo sulfato de magnésio (MG) que recebeu bolus (50 mg/kg) e IC (80 mg/kg) de sulfato de magnésio; grupo cetamina (KG) que recebeu bolus (0,5 mg/kg) e IC (1,8 mg/kg/h) de cetamina; grupo controle (CG) que recebeu bolus e IC de solução salina 0,9%. As funções cardiovasculares e respiratórias, o tempo de extubação e a pontuação de resgate pós-operatório foram registrados e descritos com nível de significância de 95% (P < 0.05). O tempo de infusão dos tratamentos foi de 21,5 ± 3,4 e 21,0 ± 2,4 minutos no KG e MG, respectivamente (P = 0.194). As taxas de infusões de remifentanil (P = 0.336) e propofol (P = 0.716) foram similares entre grupos. Na análise de dor pós-operatória as escalas não demonstraram diferenças entre grupos quanto a número de resgates, pontuação de resgate ou tempo para o primeiro resgate. Em conclusão, os protocolos propostos foram seguros e efetivos. Contudo, o sulfato de magnésio e cetamina não demonstraram analgesia pós-operatória adicional ou efeitos adjuvantes anestésicos significativos.

ABSTRACT: This study assessed the efficacy of magnesium sulfate and ketamine hydrochloride in reducing the demand for propofol, remifentanil, and postoperative rescue analgesia in cats undergoing elective ovariohysterectomy. Thirty cats were premedicated with acepromazine (0.05 mg/kg) and morphine (0.3 mg/kg) intramuscularly and induced to unconsciousness with propofol for orotracheal intubation. The continuous infusion (CI) of propofol and remifentanil were started and animals and were randomly allocated into three groups: the magnesium sulfate group (MG) received one bolus (50 mg/kg) and CI (80 mg/kg/h) of magnesium sulfate; the ketamine group (KG) received bolus (0.5 mg/kg) and CI (1.8 mg/kg/h) of ketamine hydrochloride; the control group (CG) received bolus and CI of 0.9% saline solution. Cardiovascular and respiratory functions, extubation time, and rescue postoperative scores were assessed and data were described with a significance level of 95% (P < 0.05). The infusion period of treatments was 21.5 ± 3.4 and 21.0 ± 2.4 minutes in the KG and MG, respectively (P = 0.194). The infusion rates of remifentanil (P = 0.336) and propofol (P = 0.716) were similar between groups. Analysis of the postoperative pain scales revealed no significant intergroup differences in rescue frequency, rescue score, and time to the first rescue analgesia. In conclusion, the proposed protocols were safe and effective, yet it is noteworthy that both magnesium sulfate and ketamine failed to demonstrate significant additional postoperative analgesic or adjuvant anesthetic effects.

RESUMO Objetivo: Avaliar a funcionalidade e fatores associados em crianças e adolescentes com osteogênese imperfeita (OI). Métodos: Estudo transversal com 30 crianças e adolescentes com OI. Foram avaliados prontuários médicos, uso de bisfosfonatos, características socioeconômicas, dinamometria de preensão palmar, equilíbrio, hipermobilidade articular, nível de deambulação e escores do Pediatric Evaluation of Disability Inventory - Computer Adaptative Test (PEDI-CAT). Os dados foram apresentados em média e desvio padrão e comparados por teste t por Mann-Whitney, enquanto os categóricos foram apresentados em frequência e comparados pelo teste exato de Fisher. Análises intragrupos foram realizadas por análise de covariância (ANCOVA) ou Teste de Wilcoxon para postos sinalizados. O teste Tau-b de Kendall foi usado para correlações. Resultados: A idade variou de 6 a 18 anos. A amostra foi dividida em dois grupos de acordo com a gravidade da doença. Casos moderados/graves (n=10) apresentaram menor estatura e força muscular comparadas às dos leves (n=20). Fraqueza muscular foi observada em todos os casos de OI quando comparados à população normal. Não houve diferença nos domínios do PEDI-CAT com exceção do domínio mobilidade. Houve correlação entre o número de fraturas, tipo de OI, peso e equilíbrio e o domínio mobilidade; e entre os domínios Atividades Diárias e Mobilidade e Responsabilidade e Social/cognitivo do PEDI-CAT. Conclusões: Nossos achados sugerem que crianças com OI moderada/severa podem atingir o mesmo nível de funcionalidade que crianças com a forma leve. Fraturas podem ter grande influência no nível de funcionalidade e o tratamento deve enfocar a prevenção e a reabilitação desses eventos. Objetivo .

ABSTRACT Objective: The aim of this study was to evaluate the functioning and associated factors in children and adolescents with osteogenesis imperfecta (OI). Methods: This is a cross-sectional study conducted on 30 children and adolescents with OI. Medical records, use of bisphosphonates, socioeconomic status, handgrip strength, balance, joint hypermobility, ambulatory level, and the Pediatric Evaluation of Disability Inventory—Computer Adaptative Test (PEDI-CAT) scores were assessed. Data is presented as mean and standard deviation and Student’s t-test or Mann–Whitney U test. Categorical data is presented as frequency and analyzed using Fisher’s exact test. Within-group analyses were conducted using ANCOVA or Wilcoxon signed-rank test. Correlations used Kendall’s Tau-b test. Results: The participants involved in this study were 6–18 years old. The sample was separated into two groups according to disease severity. The moderate/severe OI group (n=10) presented a lower height and muscular strength than the mild group (n=20). Muscle weakness was observed in all participants with OI when compared with the normal population. No differences were observed between the groups in the PEDI-CAT scores except for the mobility domain. There were correlations between the PEDI-CAT mobility domain and the number of fractures, OI type, weight, and balance; there was also a correlation between the PEDI-CAT daily activities, mobility, responsibility, and social/cognitive domains. Conclusions: The findings suggest that children with moderate/severe forms of OI can achieve the same function levels as children with mild OI. Fractures can have a major influence on the functional level, and treatment should focus on the prevention and rehabilitation of these events when they occur. Objective .

RESUMO Objetivo: Examinar a associação entre o tempo de tela autorreportado e os sintomas de estresse, ansiedade e depressão em adolescentes. Métodos: Foi realizado estudo com delineamento transversal com 982 adolescentes entre 12-15 anos, matriculados na rede pública de ensino da cidade de Jacarezinho (PR). Para mensurar o tempo de tela, os adolescentes responderam à pergunta: “Considerando um dia típico, quanto tempo você passa assistindo TV, jogando videogame, usando computador ou smartphone?”. O questionário DASS-21 (versão curta) foi utilizado para avaliar os sintomas de depressão, ansiedade e estresse. Análises brutas e ajustadas (idade, sexo e nível de escolaridade materna) entre tempo de tela e indicadores de saúde mental foram realizadas por meio do modelo de regressão linear generalizado, com distribuição de Poisson, adotando a significância de p<0,05. Resultados: Maiores sintomas depressivos foram observados em adolescentes com tempo de tela de 4–6 horas/dia (RP 1,35, IC95% 1,13–1,61) e ≥6 horas/dia (RP 1,88, IC95% 1,62–2,19) quando comparados com seus pares com ≤2 horas/dia. O mesmo foi observado para os sintomas de ansiedade com tempo de tela de 4–6 horas/dia (RP 1,23, IC95% 1,04–1,46) e ≥6 horas/dia (RP 1,50, IC95% 1,28–1,77); e estresse, com 4–6 horas/dia (RP 1,25, IC95% 1,08–1,44) e ≥6 horas/dia (RP 1,49, IC95% 1,30–1,71), também comparados com seus pares com ≤2 horas/dia. Conclusões: O tempo de tela foi associado positivamente com os sintomas de depressão, ansiedade e estresse em adolescentes. Atenção especial deve ser dada àqueles que passam mais de quatro horas por dia em frente a uma tela. Objetivo Métodos 98 1215 12 15 12-1 anos PR. PR .

ABSTRACT Objective: To examine the associations between self-reported screen time and symptoms of stress, anxiety, and depression in adolescents. Methods: A cross-sectional study was conducted with 982 adolescents aged between 12 and 15 years, enrolled in public schools in Jacarezinho (PR), Brazil. Screen time was assessed by the question “Considering a typical day, how much time do you spend watching TV, playing videogame, using computer or smartphone?” The DASS-21 questionnaire (short form) was used to assess symptoms of depression, anxiety, and stress. Crude and adjusted analyses (age, sex, and maternal level of education) between screen time and mental disorders symptoms were performed using general linear regression models, with Poisson distribution, with significance level at p<0.05. Results: Higher depressive symptoms were observed in adolescents who reported screen time of 4–6 hours/day (PR 1.35, 95%CI 1.13–1.61) and ≥6 hours/day (PR 1.88, 95%CI 1.62–2.19), compared with their pairs with <2 hours/day. The same was observed for anxiety symptoms with screen time of 4–6 hours/day (PR 1.23, 95%CI 1.04–1.46) and ≥6 hours/day (PR 1.50, 95%CI 1.28–1.77); and stress, with 4–6 hours/day (PR 1.25, 95%CI 1.08–1.44) and ≥6 hours/day (PR 1.49, 95%CI 1.30–1.71), also compared with their pairs with <2 hours/day. Conclusions: Screen time was positively associated with depressive, anxiety, and stress symptoms in adolescents. Special attention should be given to those who spend more than four hours a day in front of a screen.

ABSTRACT: Based on the data of China’s overseas arable land investment in 47 countries along the “Belt and Road”, the Tobit model is used to analyze the effects of cultural distance and friendship cities on the production rates of contracted arable land in China’s overseas arable land investment. This study provided theoretical basis and empirical support for promoting China’s agricultural “going abroad” and improving the production rates of contracted arable land in China’s overseas arable land investment. The results show that differences in cultural distance, power distance and the degree of uncertainty avoidance have significant positive effects on the production rates of contracted arable land in China’s overseas arable land investment, and differences in individualism have a significant negative effect on the production rates. Friendship city has a positive but insignificant effect on the production rates, meanwhile, it also weaken the positive impact of cultural distance on production rates of contracted arable land in China’s overseas arable land investment. The proportion of joint ventures with host country, the economic level and institutional environment of the host country will all have an impact on the production rates. Finally, recommendations are proposed to promote the production rates of contracted arable land, such as focusing on the positive role of cultural distance, establishing friendship cities, and investing host countries with high potential precisely.

RESUMO: Com base nos dados do investimento da China em terras aráveis no exterior em 47 países ao longo do “Cinturão e Rota”, o modelo Tobit é utilizado para analisar os efeitos da distância cultural e das cidades amigas nas taxas de produção de terras aráveis contratadas no investimento da China em terras aráveis no exterior. Os resultados mostram que as diferenças na distância cultural, na distância de poder e no grau de prevenção de incertezas têm efeitos positivos significativos sobre as taxas de produção de terras aráveis contratadas no investimento em terras aráveis no exterior da China, e as diferenças no individualismo têm um efeito negativo significativo sobre as taxas de produção. As cidades amigas têm um efeito positivo, mas insignificante, sobre as taxas de produção, enquanto estas podem enfraquecer o impacto positivo da distância cultural sobre as taxas de produção de terras aráveis contratadas no investimento em terras aráveis no exterior da China. A proporção de investimento cooperativo entre a China e o país anfitrião, o nível econômico e o ambiente institucional do país anfitrião terão um impacto sobre as taxas de produção. Por fim, são propostas recomendações para promover as taxas de produção das terras aráveis contratadas, tais como a concentração no papel positivo da distância cultural, a criação de cidades da amizade e o investimento em países de acolhimento com elevado potencial.
