This spring we are facing a real weather rollercoaster and the geopolitical situation still triggers many concerns. I hope that lecture of the new issue of Archives of Psychiatry and Psychotherapy will feed our brains with new research update and bring some quality-relaxing time. In difficult times, we need to strenghten our skills to reinforce our general and mental health. The health- and resilience- oriented perspectives are investigated by Magdalena Gawrych et al. who draw our attention to the role of connectedness and coping strategies in the mental health model. In cases when traumatizing events appear, it is crucial to evoke one’s potential towards recovery and use evidence based treatments in case of negative health outcomes such as posttraumatic stress disorder (PTSD). Dialectical Behavior Therapy (DBT) has been established as one of the methods that can be successfully used in PTSD cases, also with co-occuring borderline personality disorder – for more information read the recent paper by Michałowska and Chęć.

Offline Planning and Online Learning Under Recovering Rewards
Authors: Simchi-Levi David , Zheng Zeyu , Zhu Feng
Published: April 2024

Motivated by emerging applications, such as live-streaming e-commerce, promotions, and recommendations, we introduce and solve a general class of nonstationary multi-armed bandit problems that have the following two features: (i) the decision maker can pull and collect rewards from up to [Formula: see text] out of N different arms in each time period and (ii) the expected reward of an arm immediately drops after it is pulled and then nonparametrically recovers as the arm’s idle time increases. With the objective of maximizing the expected cumulative reward over T time periods, we design a class of purely periodic policies that jointly set a period to pull each arm. For the proposed policies, we prove performance guarantees for both the offline and the online problems. For the offline problem when all model parameters are known, the proposed periodic policy obtains a long-run approximation ratio that is at the order of [Formula: see text], which is asymptotically optimal when K grows to infinity. For the online problem when the model parameters are unknown and need to be dynamically learned, we integrate the offline periodic policy with the upper confidence bound procedure to construct on online policy. The proposed online policy is proved to approximately have [Formula: see text] regret against the offline benchmark. Our framework and policy design may shed light on broader offline planning and online learning applications with nonstationary and recovering rewards.

Published: April 2024

Objective: This study aimed to determine the frequency of true wheat allergy among pediatric patients with wheat sensitivity detected by skin prick test (SPT) in our center and to evaluate the clinical features and prognosis of the patients.

Material and Methods: This study was conducted with 63 patients who were found to have wheat sensitivity on skin prick test (SPT) between January 2017 and May 2023 in the Pediatric Allergy and Immunology Clinic of our hospital.Demographic and clinical characteristics, oral provocation tests (OPT) and prognosis of these patients were analyzed.

Results: In 9432 food SPTs, wheat positivity was detected in 63 patients and the wheat sensitivity rate was found to be 0.6%. Sixty-one point nine percent of these patients were girls. In patients with wheat atopy, 55.5% were infants between 0-6 months of age. Out of 63 patients, six (9.5%) presented with a history suggestive of IgE-mediated reaction, while 57 (90.5%) presented with a history suggestive of atopic dermatitis. Among these patients with a history of atopic dermatitis, 34 (59.6%) were found to have cow’s milk and egg atopy in addition to wheat sensitivity. Eczema exacerbation was observed in three patients on OPT performed after 2-4 weeks of short term elimination. These patients were able to consume wheat without any reaction after 6-12 months of elimination diet.

Conclusion: Wheat sensitivity not confirmed by oral provocation tests leads to unnecessary elimination of wheat, an essential nutrient. This shows the importance of OPT in patients with wheat atopy.

This text  serves as ‘vehicular medium’  or thought projection towards the existence of an ephemeral Ice memorial on a stretch of intermittently frozen sea ice in the Bering Strait at 168° 58’ 37” W. This ‘work’ is offered as a memorialisation to the consequences of collectively imagined fear—in this case the (first) Cold War. Through this text, I seek to demonstrate that this location’s historical, political and aesthetic significance can be augmented through the imagination. In short, this text is an invitation to project our thoughts towards a small but significant stretch of water in the North Pacific Ocean.
Blood Real Estate
Authors: Dadfar Farnaz
Published: April 2024

This project titled Blood Real Estate aims to emphasise notions of wounded landscapes. The images in this series are created by applying digital manipulation techniques to images sourced from photographs I have taken of various places in so-called Australia over the last five years. Through the juxtaposition of a stark monochrome aesthetic and red filters, the Australian landscape is observed as if it were a bodily skin being metaphorically scratched at, as if it were a wound about to bleed. In stressing certain interpretations of construction and the ‘dream home’, I attempt to open a space for critical reflection on the availability of land for sale, as published daily on Australian Real Estate websites. By employing dark and dystopian futuristic lenses, I intend to examine the connotation of blood and the commodification of Indigenous lands within a postcolonial era.

Optimized dielectric mirror coating designs for quasi-harmonic cavity resonance
Authors: Wei Li-Wei , Hollis Harold , Willke Benno , Spector Aaron D. , Mueller Guido
Published: April 2024

High-finesse optical cavities have a wide range of applications, some of which are bichromatic. The successful operation of high-finesse bichromatic cavities can demand careful control on the temperature dependence of the wavelength-dependent reflection phase from the dielectric mirror coatings that constitute the optical cavity. We present dielectric coating designs that are optimized for minimal differential change in the reflection phase between a quasi-second-harmonic field and its fundamental field under temperature changes. These designs guarantee cavity resonance at a wavelength of interest via the control of its quasi-harmonic field. The proposed coating designs are additionally examined for their sensitivity to manufacturing errors in the coating layer thickness with promising results.

Published: April 2024

Surface-enhanced Raman spectroscopy (SERS) has shown its ability to characterize a biological substance down to a single-molecule level without a specific biorecognition mechanism. Various nanofabrication technologies enable SERS substrate prototyping and mass manufacturing. In this study, SERS substrate simulation, fabrication, and prototyping based on two-photon polymerization (2PP) are discussed. The developed substrates showed up to 10^6 Raman signal enhancements, comparable to those of commercial substrates. Moreover, the rapid prototyping of SERS substrates based on 2PP takes less than a minute to 2 hours, depending on the fabrication approach and aspect ratio requirements. The process is well-controlled and reproducible for achieving a uniform distribution of nanostructure arrays. The developed SERS substrates can be used for a broad range of applications and the characterization of different molecules.
Child sexual abuse and its determinants among children in Addis Ababa Ethiopia: Systematic review and meta-analysis
Authors: Mekonnen Birye Dessalegn , Tsega Sintayehu Simie
Published: April 2024

Child sexual abuse is a significant public health concern and a breach of basic human rights affecting millions of children each year globally. It is typically not reported by victims, hence it remains usually concealed. Except for single studies with varying reports, there is no national studies conducted on child sexual abuse in Ethiopia. Therefore, this review determined the pooled magnitude and determinants of sexual abuse among children in Ethiopia. Potential articles were searched from PubMed, Science Direct, Scopus, and Web of science using relevant searching key terms. The Joanna Briggs Institute (JBI) critical appraisal checklist was used to evaluate the quality of all selected articles. Data were analyzed using STATA Version 14 software. Publication bias was checked using Egger’s test and funnel plot. Cochran’s chi-squared test and I2 values were used to assess heterogeneity. A random-effects model was applied during meta-analysis. The pooled prevalence of sexual abuse among 5,979 children in Ethiopia was 41.15% (95% CI: 24.44, 57.86). Sex of children (OR: 2.14, 95%CI: 1.12, 4.06), smoking (OR: 4.48, 95%CI: 1.26, 76.79), khat chewing (OR: 3.68, 95%CI: 1.62, 21.93), and alcohol use (OR: 4.77, 95%CI: 2.22, 10.25) were the determinants of child sexual abuse. The main perpetrators of sexual abuse against children were neighbors, boy/girlfriends, family members, school teachers, and stranger person. Child sexual abuse commonly took place in the victim’s or perpetrator’s home, school, and neighbor’s home. This review revealed that the magnitude of child sexual abuse in Ethiopia was relatively high and multiple factors determined the likelihood of sexual violence against children. Thus, policy-makers and concerned stakeholders should strengthen comprehensive sexual and reproductive health education to reduce the magnitude and consequences of child sexual abuse. Moreover, support with special attention should be given to children with mental illness and physical disabilities.
A quantitative assay for the assessment of cutaneous human papillomaviruses and polyomaviruses over time: A proof-of-concept in two patients with atopic dermatitis and psoriasis

Published: April 2024

The human skin virome, unlike commensal bacteria, is an under investigated component of the human skin microbiome. We developed a sensitive, quantitative assay to detect cutaneous human resident papillomaviruses (HPV) and polyomaviruses (HPyV) and we first used it to describe these viral populations at the skin surface of two patients with atopic dermatitis (AD) and psoriasis (PSO). We performed skin swabs on lesional and non-lesional skin in one AD and one PSO patient at M0, M1 and M3. After extraction, DNA was amplified using an original multiplex PCR technique before high throughput sequencing (HTS) of the amplicons (named AmpliSeq-HTS). Quantitative results were ultimately compared with monoplex quantitative PCRs (qPCRs) for previously detected viruses and were significantly correlated (R2 = 0.95, ρ = 0.75). Fifteen and 13 HPV types (mainly gamma and beta-HPVs) or HPyV species (mainly Merkel Cell Polyomavirus (MCPyV)) were detected on the skin of the AD and PSO patients, respectively. In both patients, the composition of the viral flora was variable across body sites but remained stable over time in non-lesional skin samples, mostly colonized with gamma-papillomaviruses. In lesional skin samples, beta-papillomaviruses and MCPyV were the major components of a viral flora more prone to vary over time especially with treatment and subsequent clinical improvement. We believe this method might be further used in extensive studies to further enhance the concept of an individual cutaneous viral fingerprint and the putative role of its alterations through various skin diseases and their treatments.

Published: April 2024

The unprecedented impact of the pandemic on both activities and profit of actors draws out the various areas of the value chain that need to be strengthened to ensure resilience in the face of global shock. This study fills the gap by assessing the extent at which COVID-19 impacted the profit of mango value chain actors in southern Ghana. It also analyzed the governance structure and the existing linkages in the dissemination of market information in relation to the profit of the actors. A two-year panel survey on 240 respondents was conducted in 2020 through a multi-stage sampling technique in Greater Accra, Eastern and Volta regions of Ghana. Net Farm Income, Social Network Analysis and Difference-in-Difference models were used in analyzing the data. Findings revealed that mango processors have more bargaining power and make the most profit while producers receive more information than other actors. Farmer-based organizations were found to be the prominent node and influential in the dissemination of market information within the value chain. The outbreak of COVID-19 negatively impacted the profit of mango producers and distributors; however, processors had a positive impact on their profit. The study therefore demonstrated that producers and distributors were vulnerable to the effect of the COVID-19 shock, whilst processors were robust to the shocks. Thus, reformed policies by all stakeholders for emergency preparedness should be targeted especially at those vulnerable actors in the chain. Additionally, FBOs, retailers and other key stakeholders should be considered in policy development to enhance market information dissemination.
Earnings management and readability of CSR report: Evidence from China
Authors: Ren Bangqi , Yao Sheng
Published: April 2024

The literature has confirmed that when managers increase profits through earnings management, the readability of annual reports may be reduced Lo (2017), Ye (2018). Whether this conclusion is suitable for Chinese corporate social responsibility (CSR) reports, however, is still unclear. Based on the panel data of 5083 Chinese non-financial listed companies from 2010 to 2019, this paper adopts multiple linear regression to investigate the impact of earnings management on the readability of Chinese CSR reports. The results show that: (1) There is a significant negative correlation between earnings management and the readability of Chinese CSR reports, with the readability of Chinese annual reports as a mediating variable. (2) The negative effect is more significant when companies are not punished for violations, when the internal control index is low, when companies lack ISO14001 certification and when companies do not have independent third-party authentication for Chinese CSR reports. (3) When earnings management just exceeds zero, the readability of Chinese CSR reports decreases. (4) The economic consequences of reducing the readability of Chinese CSR reports are that financing costs are increased and environmental performance is decreased. To improve the quality of information disclosure of listed companies, the recommendations are as follows: First, the government should issue CSR reporting standards to reduce the manipulation of Chinese CSR reports. Second, Chinese CSR reports disclosed by listed companies must be audited by independent third parties to enhance the credibility of the information. Third, the company needs to strengthen its external and internal supervision to reduce the manipulation space for the readability of Chinese CSR reports. This study extends the negative relationship between earnings management and the readability from annual reports to Chinese CSR reports. To prevent investors from detecting earnings management, the readability of Chinese CSR reports may be reduced. At the same time, the study has definitely added value to the existing literature in the domain of CSR.
Understanding megasporogenesis through model plants: contemporary evidence and future insights
Authors: Kaur Inderdeep , Kathpalia Renu , Koul Monika
Published: April 2024

The megasporangium serves as a model system for understanding the concept of individual cell identity, and cell-to-cell communication in angiosperms. As development of the ovule progresses, three distinct layers, the epidermal (L1), the subepidermal or the hypodermal (L2) and the innermost layers (L3) are formed along the MMC (megaspore mother cell). The MMC, which is the primary female germline cell, is initiated as a single subepidermal cell amongst several somatic cells. MMC development is governed by various regulatory pathways involving intercellular signaling, small RNAs and DNA methylation. The programming and reprograming of a single nucellar cell to enter meiosis is governed by ‘permissive’ interacting processes and factors. Concomitantly, several nucellar sister cells are prevented from germline fate also by a set of ‘repressive’ factors. However, in certain angiosperms, anomalies in development of the female gametophyte have been observed. The sporophytic tissue surrounding the female gametophyte affects the gametophyte in multiple ways. The role of genes and transcription factors in the development of the MMC and in the regulation of various processes studied in selected model plants such as Arabidopsis is explained in detail in this paper. However, as angiosperms display enormous diversity, it is important to investigate early stages of megasporogenesis in other plant systems as well. Such studies provide valuable insights in understanding the regulation of megasporogenesis and the evolution of the female gametophyte from gymnosperms to flowering plants.
Governança, relações federativas e políticas públicas
Authors: Colombo Luciléia Aparecida , Rocha Neto João Mendes da
Published: April 2024

Frequentemente, deparamo-nos com um conceito que ainda está em construção, mas presente no desenho das políticas públicas: a governança. A maioria dos programas sociais contém esta espécie de ingrediente para o bom funcionamento das políticas, o qual funciona praticamente como um diagnóstico de boas práticas, impulsionando os governos como um modelo ideal a ser perseguido. A modernização do Estado Brasileiro, realizada de forma tortuosa, propiciou o surgimento da governança como uma maneira para estabelecer novos contornos para o relacionamento entre Estado, Sociedade e agora também o mercado, uma vez que admitimos que o alcance do Estado é limitado em algumas pautas, sendo que os agentes privados podem agir para o financiamento e execução de algumas destas políticas, através das parcerias público-privadas.
Diferentes padrões de coordenação estadual
Authors: Segatto Catarina Ianni , Lima-Silva Fernanda , Silva André Luis Nogueira da
Published: April 2024

O fortalecimento da coordenação nacional, que ocorreu nas últimas décadas no Brasil, resultou na indução à implementação de diversas políticas públicas por governos subnacionais, incluindo aquelas cuja execução envolvia a coordenação entre estados e municípios. No entanto, isso variou entre as políticas. Naquelas com maior coordenação nacional, os governos estaduais assumiram um papel de coordenação regional junto a seus municípios, mas, naquelas com menor indução nacional, prevaleceu uma maior heterogeneidade. Este estudo aprofundará a compreensão sobre a coordenação dos governos estaduais em três políticas - Educação, Saúde e Proteção e Defesa Civil - a partir da análise da influência da coordenação nacional e de fatores dos contextos e dinâmicas subnacionais no desenvolvimento de padrões distintos de coordenação estadual. Os casos escolhidos - Educação (alfabetização) no Ceará, Saúde (AIDS) em São Paulo e Proteção e Defesa Civil (gestão de risco de desastres) no Acre - representam políticas com diferentes graus de coordenação federativa e padrões de coordenação estadual. A análise exploratória e qualitativa de estudos já realizados, de documentos e de entrevistas semi-estruturadas mostra que os padrões de coordenação estadual resultaram das capacidades e legados prévios e da atuação de determinados atores. No entanto, a coordenação nacional foi relevante no caso de São Paulo para a continuidade dessa política ao longo do tempo.
Positivismo reconsiderado

Published: April 2024

Como a filosofia positivista contribuiu para a consolidação da disciplina de Relações Internacionais, especificamente no que tange ao modelo de explicação dos fenômenos internacionais? Nesse artigo, recuperamos a história do positivismo, focando no Círculo de Viena, os princípios da filosofia positivista e o modelo explicativo dedutivo-nomológico. Utilizamos essa abordagem filosófica para analisar as contribuições do positivismo para as RI, nomeadamente no que tange à produção de explicações. Argumentamos que a consolidação da disciplina enquanto ciência dos fenômenos internacionais se deve em larga medida ao positivismo e aos seus princípios filosóficos para a construção do conhecimento.

Qual o efeito do plano municipal de resíduos sólidos sobre a recuperação de lixo urbano, entre outros objetivos a serem atendidos através da Política Nacional de Resíduos Sólidos (PNRS)? Este trabalho testa a hipótese de que a presença de um Plano Municipal de Gestão Integrada dos Resíduos Sólidos (PMGIRS) não é suficiente para promover a gestão adequada dos resíduos sólidos. Fazemos uso dos dados disponibilizados pelo Sistema Nacional de Informações Sobre Saneamento (SNIS) e o Índice de Sustentabilidade da Limpeza Urbana (ISLU) durante os anos 2014 a 2020 para os municípios brasileiros. Metodologicamente, empregamos o modelo de Diff-in-Diff tradicional e também com tendências paralelas para estimar o efeito do PMGIRS na gestão dos resíduos sólidos urbanos, utilizando o ISLU e suas dimensões, como proxy de adesão aos objetivos da PNRS. Nossos resultados indicam que a criação do PMGIRS promove um aumento na adesão da Política Nacional de Resíduos Sólidos, como também no tratamento de resíduos sólidos do município.

Boas políticas demandam expertise para serem elaboradas. Nosso objetivo é demonstrar que há especialistas nas comissões brasileiras que se dedicam majoritariamente às principais jurisdições do Legislativo. Analisamos o tempo de legislatura que cada deputado permaneceu na mesma comissão entre 1995 e 2014. Os dados são oriundos do Banco de Dados Legislativos do CEBRAP e da Secretaria-Geral da Mesa da Câmara dos Deputados. As análises foram feitas tanto de forma descritiva, quanto a partir de regressão linear multivariada. Nossos resultados demonstram que, embora haja rotatividade, há também um grupo considerável de parlamentares que permanecem boa parte da legislatura nas mesmas comissões. Isso ocorre majoritariamente nas comissões com mais membros do Legislativo, isto é, as mais ambicionadas, demonstrando uma atenção especial dos atores legislativos a essas jurisdições e indicando uma coordenação partidária do sistema de comissões.

Identification of Hand Tremor Levels in Shooting Activities Under Different Shooting Positions Using a Low Cost and Portable System
Authors: Saputra Jeki , Santoso Didik Rahadi , Dharmawan Hari Arief , Hasanah Rini Nur
Published: April 2024

The accuracy level is important in shooting activities and depends on many factors, such as hand tremors as body vibration and shooting position. Achieving high accuracy in different shooters is challenging, especially in the case of different shooting positions. However, there is a lack of information about the influence of shooting positions and experiences on a shooter’s body vibration and accuracy levels. Thus, this study aims to develop a portable and low-cost hand tremor measurement device (as a function of body vibration) to identify the influence of hand movement on shooting accuracy. For this purpose, low-cost accelerometer sensors and a microcontroller were used as the measurement kit. Three different shooting positions (squatting, standing, and prone) were analyzed. The shooters were classified into novice and expert groups. Each group had five participants with standard fire guns and accelerometer kits. These participants were asked to shoot the target to get their best accuracy. Besides, the hand tremor level data from the self-developed kit were recorded to investigate the hand tremors. The results show that the novice participants have more hand tremors in all shooting positions. There are significant differences between the squatting, standing, and prone positions in hand tremors for novice and expert participants. In the expert group, the prone and squatting positions have the least vibration level, indicated by the least acceleration (0.01 - 0.04 m/s2 for the expert group and 0.02 - 0.11 m/s2 for the novice group). The best accuracy for all positions is also obtained from expert shooters. It can be concluded that different shooting positions are related to the body vibrations. The expert shooters have a lower body vibration than the novice participants. The hand tremor levels may influence the accuracy level since different shooting positions and experiences have different vibration and accuracy levels
Effect of Thermodiffusion on Non Premixed Flame in MILD Regime Using a Modified Reacting Solver
Authors: Srinivasarao Muddada , Reddy Vanteru Mahendra
Published: April 2024

Numerical simulations for moderate and intense low oxygen dilution (MILD) combustion with essential solvers and detailed mechanisms involve more complications and computational time. Various advanced combustion modeling techniques have recently been developed to study MILD combustion characteristics. However, every combustion model has specific issues predicting the temperature and emissions of the MILD combustion flames. The diffusive nature of the MILD flame is considered, and individual Lewis numbers are investigated on a non-premixed flame. The current study analyzes the methane/hydrogen flame propagation with different Lewis number combinations in a hot co-flow environment.Individual Lewis numbers for methane and hydrogen are investigated from stochiometric to ultra-rich mixtures in non-premixed flames. Several numerical simulations are performed in the OpenFOAM9 environment using a modified EDC model with tuned turbulence and combustion model constants. The numerical simulation results with hydrogen and methane Lewis numbers of 0.4 and 0.9, respectively, show promising agreement with the experimental findings of Dally et al. [1]. Various combustion parameters are studied with different CH4 and H2 Lewis number combinations. In addition, the unity Lewis number case is simulated and compared to the situations that are taken into consideration.
Numerical Estimation of Convective Heat Transfer Coefficient and Heat Flux for a Supersonic Rocket Nozzle
Authors: Makhija Amit , Bodi Kowsik , Chakraborty Debasis
Published: April 2024

Rocket nozzles are often cooled by passing liquid propellants through channels in the nozzle walls. Estimating heat transfer to the wall from the hot gases in the nozzle is essential in deciding on the coolant flow requirements. The present work examines the computational estimation of convection heat transfer to the nozzle walls for compressible turbulent flows. Computations were performed using the rhoPimpleFoam solver in OpenFOAM® with two different turbulence models. We simulate the supersonic flow over a flat plate and validate the heat flux calculation method and turbulence model characteristics. We compare two methods of calculating convection heat transfer in the context of the nozzle flow case presented by Back & Massier. We find that the realizablek-ε turbulence model works well in estimating the heat transfer coefficient.

Published: April 2024

Ammonia is becoming increasingly popular as a carbon-neutral fuel with zero carbon dioxide emissions. However, a significant hurdle lies in its combustion, which leads to substantial emissions of NOx. The current research involves conducting a chemical kinetic investigation to examine the characteristics of Intense Low oxygen Dilution (MILD) or Moderate combustion in ammonia (NH3)/air flames. This study is carried out under specific conditions, such as oxygen concentrations ranging from 11to 23%, premixed reactant temperatures between 1300 and 1700 K, and a pressure of one atmosphere. The study focuses on investigating the combustion characteristics of MILD using dilution with H2O and N2.With the rise in the inlet temperature of the premixed reactant, the peak temperature of the flame also rises. Moreover, flames diluted with H2O exhibit lower peak temperatures compared to flames diluted with N2.Flames diluted with H2O result in lower NOx emissions compared to flames diluted with N2. Additionally, for N2diluted flames, the exit NOx emissions rise as the oxygen concentration increases.Despite this, NOx emissions from H2Odiluted flames demonstrate non-monotonic behaviour.This means that the exit NOx increases initially as the oxygen concentration reaches 21%, but then begins to decrease. In contrast to N2and H2Odiluted flames exhibits a wider regime of no-ignition.Moreover, the rise in peak temperature in H2Odiluted flames is less apparent than in N2diluted flames, corresponding to broader ranges MILD combustion ranges.Furthermore, to attain MILD combustion in H2O diluted flames at a specific O2 concentration, the temperature of reactant needs to be higher than that required for N2diluted flames.

Attempts to accurately reconstruct events that occurred during the final phases of the 1845 Franklin Northwest Passage expedition face a key challenge: how to address inconsistencies and, in some cases, contradictions between historical descriptions of sites and the archaeological evidence they contain. This paper examines the case of site NcLa-1 at Kungearkbeearu, on the Simpson Strait coast of King William Island, for which the Inuit oral history seems incompatible with archaeological interpretations. New archaeological data from the site provide an enhanced framework within which to evaluate both the oral history and archaeology of NcLa-1.

Os antimicrobianos são substâncias naturais ou sintéticas capazes de eliminar ou impedir a multiplicação de bactérias. O uso inadequado tornou-se um grave problema de saúde pública, ocasionando a resistência bacteriana. As causas abrangem desde a realização incompleta do tratamento, erro no horário da administração, da dosagem sugerida até mesmo o uso do fármaco incorreto para a situação clínica. O objetivo do trabalho foi realizar uma revisão integrativa sobre a automedicação de antibacterianos em nível nacional, demonstrando os impactos para a saúde. Os trabalhos selecionados foram lidos integralmente, avaliando a relevância no questionamento abordado e a contribuição nessa temática. Dados como autor, ano, estado, município, objetivo, metodologia e resultados foram extraídos e organizados em um quadro, dessa forma visualizando as respectivas propostas abordadas. A ideia central de cada artigo foi sintetizada e abordada com trabalhos adjacentes, contextualizando as informações e enriquecendo a discussão. Dos 195 artigos, apenas 7 foram selecionados conforme o protocolo de pesquisa. Os estados envolvidos nos trabalhos são Amazonas [4], Goiás [2] e Minas Gerais [1]. Portanto, o uso inapropriado de antimicrobianos sem a prescrição adequada contribui para o aumento de cepas resistentes, sendo necessária uma fiscalização contundente em todos os ambientes de distribuição, em especial nas farmácias comerciais.

Published: April 2024

Becoming an effective language teacher does not only depend on how well the teacher knows the language but also on how the teacher can deal with the complex situations that emerge in the profession. Therefore, it is crucial to provide novice teachers with opportunities to share with others these complications during their teaching training programs. This document has the purpose of presenting the results of a research which aims to explore how novice language teachers mediate their discussions while they reflect on the emerging conflicts that they have faced during their initiating teaching practice. The study has a twofold purpose: to inquire about the main hardships these teachers deal with and the implications of mediation in their solution.  Twelve English language teachers were involved as participants who were grouped in four groups of three each to discuss during 6 sessions. The study used a mixed method research approach that involved discourse analysis of the transcribed discussions, the teachers’ diaries and open observations by the researchers.  The results show that socializing conflicts leads to cognitive, social and affective dimensions of mediation; in such a way that mediation reinforces teacher’s self-efficacy and decision making to solve their problems.
Política educativa y apropiación de la dimensión intercultural

Published: April 2024

En 2017, el Ministerio de Educación de Colombia emitió la Resolución 18583, la cual establece los criterios de calidad de los programas de formación docente o licenciaturas. A través de una investigación cualitativa exploratoria y descriptiva, se indagó sobre cómo las licenciaturas abordaron la política y, en particular, cómo se apropió la dimensión intercultural en 27 licenciaturas de distintas ciudades del país. Las fuentes de datos incluyeron proyectos educativos, microcurrículos y entrevistas a directivos y profesores. Los resultados indican que las estrategias de apropiación de la política incluyeron la conformación de comités para discutir las implicaciones de la directriz, cambios a nivel curricular que implicaron la transversalización de las perspectivas interculturales y la inclusión de nuevos cursos en la malla curricular. La interculturalidad se apropió como un eje misional, tanto desde lo teórico como desde lo práctico, basándose en visiones mayoritariamente constructivistas. Mientras tanto, la comprensión de la política, en términos generales, se vio limitada debido a la ausencia de un enfoque intertextual por parte de los agentes implicados en su interpretación. Como conclusión, se argumenta que un mayor diálogo entre los diferentes miembros de la comunidad académica podría generar procesos de comprensión y apropiación de la política más efectivos.
Variación interlingüística en la conciencia léxico-semántica de dos perfiles bilingües disímiles
Authors: Aguirre Garzón Julián David
Published: April 2024

El objetivo de este artículo fue diferenciar los factores de metalengua, de asertividad y discriminación semántico-lexical en una traducción en estudiantes de una licenciatura en idiomas que contempla dos rutas de aprendizaje diferentes en una universidad estatal. El enfoque mixto inductivo-deductivo que se implementó permitió clasificar los resultados de ejecución de la muestra de manera más amplia y a detalle con respecto a la frecuencia, duración, comportamiento, recursividad y usos de la L1 y la L2, frente a la traducción de un extracto narrativo. La población estuvo constituida por 10 sujetos entre los 21 y 35 años, que se encuentran en su último semestre. Los instrumentos de recolección y análisis de datos fueron: Translog 2.0, una encuesta diagnóstica, la Traducción y Re-Traducción (revisión de traductores expertos en textos especializados), el diccionario-corpus Linguee y una lista de cotejo. La investigación permitió romper con las asociaciones referentes a las comunidades bilingües y el bilingüismo, en vista de ciertos rasgos como las competencias traductoras y lingüísticas diversas. Se concluye que los estudiantes de traducción manejan un rango de vocabulario ampliamente más especializado, incurren menos en la literalidad de un itinerario de expresiones, menos indicadores de hipercorrección y mayor empleo de figuras literarias.
