Limite e além: obra de arte, acontecer poético e cidade
Authors: Lira André
Published: February 2025

Que quer dizer e onde está o limite? Proporemos um caminho de pensar tais questões desde um pensar poético, que procura encontrar modos de manifestar concretamente o limite como presença. Discutiremos como limite não é simplesmente imposição de uma regra, mas também a própria eclosão do ser sendo, sem que se possa distinguir limite e limitado. Apontaremos, hermeneuticamente, para a instância originária que a obra de arte instaura como não só o que torna os limites visíveis, mas o que possibilita seu atravessamento. Pensaremos, por fim, a relação entre artista, obra de arte e cidade desde o poético.
Que tens, Caralho?: aspectos cômicos e rebeldes em O elixir do pajé, de Bernardo Guimarães
Authors: Feitosa George Antonio Correia , Martins Edson Soares
Published: February 2025

Bernardo Guimarães, em O elixir do pajé, traça na imagem do corpo masculino um projeto poético que, segundo Candido, assumiu uma atitude ao mesmo tempo rebelde e militante. Soma-se a essa atitude uma naturalização vocabular que coincide com a visão utópica defendida por Bakhtin em seu estudo acerca da comicidade popular. As imagens do falo personificado e do indígena eremita ferem a lógica romântica tradicional, que antes servira a uma dimensão erudita. Propomo-nos aqui a examinar a forma do poema em busca de identificar em sua estrutura as formas que lhe conferem os elementos que agridem e rebaixam os valores literários tradicionais.
Detecting Subtle Shifts: Comparing SME Performance Drivers Pre and During the Covid-19 Pandemic
Authors: Simango Soza , Zhou Helper
Published: February 2025

Small and Medium Enterprises (SMEs), especially those in the South African tourism sector, were significantly impacted by the Covid-19 pandemic. Many experienced a decline in performance due to decreased consumer demand resulting from travel restrictions. Understanding these enterprises’ performance pre and post the pandemic will provide insights into how enterprise development practitioners and policy makers could best respond to crises such as this. The study harnessed the Resource-Based View theory to unveil subtle shifts in SMEs’ performance drivers due to the impact of the pandemic. This is important as pre-Covid-19, tourism SMEs with sufficient resources and capabilities were likely to enjoy a competitive advantage and better performance than those lacking such. However, the pandemic disrupted many of these resources and capabilities as travel restrictions and decreased demand made it difficult for SMEs to maintain their customer base or invest in new markets. The Difference in Difference (DID) technique was employed due to its ability to isolate the impact of the pandemic on firm performance by comparing pre- and post-Covid-19 features. As expected, the results showed that the pandemic negatively impacted South African tourism SMEs. This was evident in decreased total asset value, sales volumes, revenue and the number of product offerings. Surprisingly, it was found that having a business plan in place negatively impacted performance before Covid-19. However, post-pandemic, business planning was a crucial positive driver of SME performance. Company age negatively impacted performance post the pandemic, indicating organisational rigidities among tourism SMEs during crises. Despite being home to the popular Garden Route, the Western Cape province suffered more negative effects than other provinces. Lastly, entrepreneur experience and business incubation positively impacted SME performance during the pandemic. Based on these findings, it is recommended that key stakeholders take the evolving performance drivers in the SME sector into account in order to craft support measures that lead to increased, sustainable business performance.

Modeling of polymer processing of thermoplastic polymers: application to the injection molding process
Authors: Speranza Vito , Liparoti Sara , Titomanlio Giuseppe , Pantani Roberto
Published: February 2025

In the transformation operations of polymeric materials, there is a complex interplay between transport phenomena and crystallization. In particular, the polymer in the molten state is a viscoelastic fluid with rheological parameters depending on temperature, pressure, crystallinity, and molecular stretch. The molecular stretch is a tensor variable with values determined by the history of the flow, temperature, and pressure fields. During polymer processing operations, several phenomena proceed simultaneously by interacting with each other. The combination and interplay of the models that describe each of the phenomena mentioned above provides the evolution of all the relevant quantities and, therefore, also the overall model that describes the evolution of the solidification that generally proceeds starting from the walls (where the temperature is lower and furthermore the shear is higher). This work presents an overall model of the behavior of an isotactic polypropylene during the injection molding process. The model includes the kinetics of spherulitic and fibrillar crystallization and their dependence on the level of molecular stretch; the modeling is carried out up to the prediction of molecular stretch and morphology distributions along the molded part thickness. The model predictions satisfactorily describe the evolution of temperature and pressure during the process and the fundamental aspects of the morphology distribution inside the part.
Production of a starch-based polymeric coating with incorporation of bioactive principles from chemical synthesis to extend the shelf life of cavendish banana

Published: February 2025

Crown rot is a severe postharvest disease affecting tropical and subtropical fruits like mango, avocado, papaya, and banana. It is caused by fungal pathogens that penetrate the fruit, reducing its pulp and leading to premature ripening. Systemic fungicides have been used to control these fungi, typically applied to seeds, leaves, or fruits to prevent disease spread. However, traditional fungicides can pose toxicity risks to the environment and human health. Essential oils are chemical substances that can be found in plants and have antifungal capacity. Essential oils are being investigated as an alternative to traditional fungicides since they are less toxic to the environment and human health; however, they are more expensive and less efficient than traditional fungicides. Accordingly, chemically synthesizing the chemical compounds that are the active antifungal agent inside essential oils can be an ecological and effective approach to produce a new generation of antifungals. In this study, modified starch was investigated as a carrier for thymol (active antifungal agent in thyme oil) incorporation using four distinct methods. Emulsions of starch and thymol were prepared and spray dried to obtain a soluble powder that was used to produce coatings. The most effective method for thymol incorporation yields a retention of approximately 40% according to gas chromatography analysis. In-vitro results indicated that thymol incorporated into the matrix exhibited antifungal effects against key fungi responsible for crown rot disease in Cavendish bananas at concentrations greater than 6% w/w relative to the coating matrix.
Modelling hydrolytic, thermal, and mechanical degradation of PLA during single-screw extrusion
Authors: Velghe Ineke , Buffel Bart , Vandeginste Veerle , Thielemans Wim , Desplentere Frederik
Published: February 2025

Since melt processing causes degradation of poly(lactic acid) or PLA, it is crucial to understand the effect of extrusion conditions on the molecular weight reduction. Kinetic models found in literature are promising tools to describe hydrolytic, thermal, and mechanical degradation during extrusion. In order to use these models, extrusion parameters (that are equipment dependent) should be translated into the four fundamental parameters that determine degradation: moisture content in PLA, residence time, shear stress history and temperature history. This work presents a methodology to use numerical simulations to translate extrusion parameters into fundamental parameters. The results show that numerical simulations can be used successfully to describe the extrusion process based on residence time, shear stress history, and temperature history.

As a partner school, SMAN 3 Kupang Tmur, which is located in Kupang Regency, NTT Province, has several problems experienced by teachers and students for chemistry subjects, namely limited and inadequate laboratory equipment, the need for very minimal and insufficient practical materials so that activities Practicums are very rarely carried out due to the very expensive cost of materials, the unavailability of good and clear practicum guides, limited time availability from teachers due to the absence of laboratory assistants, and also insufficient laboratory space. Seeing these obstacles, in this activity teachers and students need to be provided with introductory chemistry practical activities because through practical activities they can increase students' knowledge and can provide illustrations or introduce important concepts of chemistry, train students to improve their reasoning, imagination and thinking skills. rational in seeking the truth, training students to apply scientific attitudes such as curiosity, perseverance, thoroughness, caution, objectivity, in dealing with all problems so that they do not easily believe in something that is not certain to be true, and making students more active in thinking and acting in their efforts search for truth or evidence of a theory being studied. Seeing the problems above and remembering how important practicum activities are in learning chemistry, practicum activities in schools will continue. The result of this activity is an increase in laboratory management skills and process skills by the students of SMAN 3 East Kupang.
High-Dose Bupropion for Depression
Authors: CDA-AMC
Published: February 2025

What Is the Issue?

Bupropion is a drug used in the treatment of depression. Bupropion is 1 of many treatment options available for depression and is associated with several side effects as well as the potential for misuse. The risk of side effects may be increased with higher daily doses of bupropion; therefore, it is important to determine the appropriate dosing for bupropion for the treatment of depression.

What Did We Do?

To help determine the appropriate dosing of bupropion for the treatment of major depressive disorder and treatment-resistant depression in adults, we sought to identify and summarize studies of the clinical efficacy and safety of high-dose (301 mg per day to 450 mg per day) versus standard-dose (≤ 300 mg per day) bupropion. We also sought to identify and summarize recommendations on the use of high-dose bupropion for the treatment of depression in evidence-based guidelines.
We searched key resources, including journal citation databases, and conducted a focused internet search for relevant evidence, published since 2014. One reviewer screened articles for inclusion, based on predefined criteria.

What Did We Find?

We did not identify any studies that evaluated the clinical efficacy and safety of high-dose versus standard-dose bupropion for the treatment of depression, which met our criteria for this review.
We did not identify any evidence-based guidelines that included recommendations on the use of high-dose bupropion in adults with depression that met our criteria for this review.

What Does it Mean?

We cannot draw conclusions on the use of high-dose bupropion for the treatment of major depressive disorder or treatment-resistant depression in adults due to the lack of identified studies or evidence-based guidelines that met our criteria for this review. Future studies that compare high-dose and standard-dose bupropion for the treatment of depression could aid decision-making around the subject area of appropriate bupropion dosing.

Published: February 2025

O presente artigo científico tem como foco analisar, a partir de relatos de docentes, os principais desafios, dificuldades e oportunidades encontrados em relação à educação remota e a inclusão da tecnologia no cotidiano do ambiente profissional. A tecnologia não deve ser tratada como um empecilho para o professor ensinar, mas sim como uma ferramenta pedagógica inovadora e dinâmica para um ensino contextualizado. Diante de tal perspectiva, abandonar o tradicionalismo no ensino é necessário para compreender que a aprendizagem não acontece somente mediante o uso do livro didático ou falas do professor, mas também na interação, seja ela virtual ou não. No cenário Pós-Pandemia é de suma importância que o professor reinvente-se e supere o medo de inovar em sua prática docente, principalmente diante do avanço das tecnologias que, mais do que nunca, estão presentes no dia a dia dos discentes. Ensinar exige mais do que transmitir conteúdo, é necessário entrar no mundo virtual, onde o educador também pode agir pedagogicamente.

Published: February 2025

Abstract. Ozone (O3) pollution is posing significant challenges to urban air quality improvement in China. The formation of surface O3 is intricately linked to chemical reactions which are influenced by both meteorological conditions and local emissions of precursors (i.e., NOx and volatile organic compounds, VOCs). When meteorological conditions deteriorate, the atmosphere's capacity to cleanse pollutants decreases, leading to the accumulation of air pollutants. Although a series of emission reduction measures have been implemented in urban areas, the effectiveness of O3 pollution control proves inadequate. Primarily due to adverse changes in meteorological conditions, the effects of emission reduction are masked. In this study, we integrated a machine learning model, an observation-based model, and a positive matrix factorization model based on 4 years of continuous observation data from a typical urban site. We found that transport and dispersion impact the distribution of O3 concentration. During the warm season, positive contributions of dispersion and transport to O3 concentration ranged from 12.9 % to 24.0 %. After meteorological normalization, the sensitivity of O3 formation and the source apportionment of VOCs changed. The sensitivity of O3 formation shifted towards the transition regime between VOC- and NOx-limited regimes during the O3 pollution event. Vehicle exhaust became the primary source of VOC emissions after “removing” the effect of dispersion, contributing 41.8 % to VOCs during the pollution periods. On the contrary, the contribution of combustion to VOCs decreased from 33.7 % to 25.1 %. Our results provided new recommendations and insights for implementing O3 pollution control measures and evaluating the effectiveness of emission reduction in urban areas.
Combined effects of topography, soil moisture, and snow cover regimes on growth responses of grasslands in a low- mountain range (Vosges, France)
Authors: Herrault Pierre-Alexis , Ullmann Albin , Ertlen Damien
Published: February 2025

Abstract. Growth responses of low-mountain grasslands to climate warming are poorly understood despite very large surfaces being covered in central Europe. These grasslands are characterized by still-present agricultural exploitation and complex topographical features that limit species migration and increase differences in snow regimes. This study examined MODIS surface reflectances between 2000 and 2020 across the Vosges mountain grasslands to investigate trends and drivers of spatial patterns in the annual maximum NDVI (normalized difference vegetation index). We found that a majority of grasslands indicate no significant trends, which possibly reveals several environmental and ecological compensatory effects in response to warming in the Vosges Mountains. We also noted hotspots of browning grasslands (a decrease in annual maximum NDVI), largely overrepresented compared to the greening ones (an increase in annual maximum of NDVI), a pattern which contradicts most productivity signals highlighted in European high-mountain grasslands. Spatial patterns of browning are enhanced on north-facing slopes and at low elevations (<1100 m), where high-producing grasslands with dominant herbaceous communities prevail. A low soil water recharge also appears to be pivotal in explaining the probability of browning at the study site. Through the use of winter habitat indices, we noted high responsiveness of low-mountain grasslands to differences in intra-seasonal snow regimes, partly modulated by topographic features. Prolonged and time-continuous snow cover promotes higher peak productivity and shortened green-up periods. A high number of frost events results in lower peak productivity and prolonged green-up periods. We hypothesize that observed growth responses in the Vosges Mountains are indicative of long-term future responses to climate warming in high-mountain ranges. With shorter and more discontinuous snow cover, we expect higher diversity of growth responses in European low-mountain grasslands due to strong contextual effects and high terrain complexity.
WRF-Chem simulations of snow nitrate and other physicochemical properties in northern China

Published: February 2025

Abstract. Snow is a key component of the cryosphere and has significant impacts on surface energy balance, hydrology, atmospheric circulation, etc. In addition, numerous studies have indicated that snow impurities, especially nitrate, are sensitive to sunlight and can be photolyzed to emit reactive species including NO2 and HONO, which serve as precursors of O3 and radicals and disturb the overlying atmospheric chemistry. This makes snow a reservoir of reactive species, and this reservoir is particularly important in remote and pristine regions with limited anthropogenic emissions. The magnitude of snow chemical emissions is also influenced by snow physical properties, including snow depth, density, and concentrations of light-absorbing impurities (e.g., black carbon (BC) and dust). Exploring and elucidating the emissions and atmospheric consequences of the snow-sourced reactive species require a global or regional model with a snow module. Here, we parameterized atmospheric nitrate deposition and its distributions in snow using a regional chemical transport model, i.e., WRF-Chem (Weather Research and Forecasting Model coupled with Chemistry), and evaluated the performance of WRF-Chem in simulating snow cover; snow depth; and BC, dust, and nitrate concentrations with field observations in northern China, which is one of the regions with a dense and prolonged snow cover. In general, the model-simulated spatial variability in nitrate mass concentrations in the top snow layer (hereafter NITS) is consistent with observations. Simulated NITS values in northeast China from December 2017 to March 2018 had a maximum range of 7.11–16.58 µg g−1, minimum range of 0.06–0.21 µg g−1, and 4-month average of 2.72 ± 1.34 µg g−1. In comparison, observed values showed a maximum range of 9.35–33.43 µg g−1, minimum range of 0.09–0.51 µg g−1, and average of 3.74 ± 5.42 µg g−1. The model results show an underestimation especially in regions closes to large cities in northeastern China, most likely due to the underestimation of NOx emissions in these regions. Additionally, nitrate deposition, snowpack accumulation processes, and challenges in capturing fine-scale emission variability may also contribute to the bias. These results illustrate the ability of WRF-Chem to simulate snow properties including concentrations of reservoir species in northern China, and in the future, we will incorporate snow nitrate photolysis in the model, exploring the emissions of snow NOx from nitrate photolysis and the impacts on local and regional atmospheric chemistry and air pollutant transformations.

Published: February 2025

Objetivo. A catalogação, um dos alicerces da Biblioteconomia, é a ação de representar um item através da descrição. O bibliotecário, através desta atividade, organiza o conhecimento por meio da classificação e estabelece relacionamentos através dos assuntos indexados. Em bibliotecas universitárias, este processo técnico passa por atualizações, visto que o avanço das tecnologias influencia diretamente no trabalho do bibliotecário. O objetivo deste estudo é analisar o uso da ferramenta ChatGPT versão 3.5 para o processamento técnico (catalogação, indexação e classificação) de materiais no Setor de Tratamento da Informação da Biblioteca Central Irmão José Otão da PUCRS. A revisão da literatura trata sobre a representação da informação, modalidades de Inteligência Artificial (IA), origem e características do ChatGPT, possibilidade de uso do chatbot no processamento técnico e questões éticas da ferramenta.
Método. Estudo exploratório que apresenta um levantamento bibliográfico de referencial teórico que contempla as temáticas de IA, catalogação e bibliotecas e um relato de experiência dos testes realizados pelo Setor de Tratamento da Informação da Biblioteca da PUCRS. O relato de experiência dos testes realizados mostra as análises do uso do ChatGPT na catalogação, indexação e classificação.
Resultados. A partir dos testes realizados, percebe-se a possibilidade de uso do ChatGPT para apoio às atividades relacionadas ao processamento técnico, como indexação e classificação. Na descrição dos dados, embora a ferramenta possa ser útil para bibliotecas que utilizem o AACR2 como código de catalogação, a descrição em RDA precisa ser aprimorada através de treinamento do chatbot com campos MARC21 para RDA.
Conclusões. Com mais desenvolvimento e aprimoramento, o ChatGPT tem o potencial de auxiliar os profissionais da informação e facilitar a descoberta das coleções das bibliotecas. No entanto, é essencial estar atento às fraquezas e armadilhas que a ferramenta pode apresentar. A avaliação crítica por parte dos profissionais habilitados será fundamental para interpretar as informações geradas pela ferramenta.

Published: February 2025

Artificial Intelligence (AI) has seen a significant rise in public use since the release of ChatGPT in November of 2022. Higher education institutions (HEI) have struggled to negotiate how best to manage AI technologies within their academic communities, acknowledging both positive and negative impacts of AI on education. Focused primarily on large language model (LLM) technologies, such as ChatGPT, HEIs are working to build policies and guidelines to regulate their use. However, within these policies, few HEIs have considered AI meeting assistants, even though these applications bring their own set of benefits and risks. This article examines the public websites of 135 CPED universities, eight of which mention AI meeting assistants in their policies. The article analyzes the risks, benefits, and use guidance provided by these policies and suggests next steps for HEIs to address the ethical, legal, and pedagogical implications of AI meeting assistants.

La condición digital ha modificado no solo el estatuto de la creación fotográfica sino también el de aquellas fotografías previas a su llegada que, con fines de preservación o archivo, se han visto sometidas a digitalización. Entre otras consecuencias derivadas, la conversión de estas fotografías en meras imágenes ha comportado la obliteración de ciertos rasgos materiales, como las marcas e inscripciones al dorso, de especial importancia para su adecuada caracterización. Tomando como caso paradigmático la producción amateur del contingente alemán en la Segunda Guerra Mundial, la investigación plantea cómo el estudio de estos signos físicos permite no solo contextualizar y datar las fotografías sino obtener informaciones acerca de su intención original, su valor de uso o las circunstancias concurrentes en su circulación, aspectos todos ellos de enorme relevancia en este caso particular. A fin de ensayar la pertinencia de este tipo de análisis, el artículo analiza de manera directa un corpus de fotografías originales e inéditas hasta la fecha y fija su atención en ciertas tipologías particularmente significativas.

The application of artificial intelligence (AI) in a variety of fields is examined in this article, with a particular focus on its potential in the treatment of depression. AI applications such as smart assistants like Siri, Google Translate, and Amazon Alexa, as well as Tesla cars, are examples that enhance daily life and increase efficiency. Generative AI models like ChatGPT, which use natural language processing (NLP) technologies, in many different fields., including text generation, translation, customer service. Artificial Intelligence's role in diagnosing and treating depression is also significant; NLP tools, emotion recognition technologies, and AI-supported digital therapies have been developed to detect depression symptoms. AI-based mobile apps and wearable devices help with early detection of depression symptoms and ease the adaptation to treatment. However, ethical concerns and data security issues are important factors to consider in the use of AI. The role of AI in depression treatment will have a significant impact on shaping future therapeutic approaches.

Measuring the Cultural and Socio-economic Effects of STEMAC R & D Activities
Authors: Pozzo Riccardo
Published: February 2025

Measuring impact is fundamental to improving the social acceptability of public investment in social and cultural infrastructures, as it can provide a basis for aligning research and innovation with society's values, needs and expectations. Looking at the potential of social and cultural innovation, a specific innovation in the cultural and creative industries is increasingly the result of a complex co-creation process involving knowledge flows throughout the economic and social environment. It has therefore become increasingly clear that co-creation plays a central role within the open innovation of STEMAC R&D. However, an accepted methodology for impact assessment is still lacking. The aim of this paper is to develop and test a methodology to measure the impact of technology transfer from basic research and development to industrial application and its cultural and socio-economic effects.

Authors: Wahyuni Amelia Putri , Katminingsih Yuni , Widodo Suryo
Published: February 2025

This study aims to determine whether or not there is an effect of the problem-based learning model on students' mathematics learning outcomes and the difference in the amount of influence based on level. Due to the variety of research results on this topic, a meta-analysis research was conducted to evaluate as a whole. This research analyzed 14 data studies consisting of articles and theses at the junior high school and high school levels, with the help of Ms Exel and JASP software. The results of this study indicate that the problem-based learning model has an effect on students' mathematics learning outcomes, as evidenced by the p-value <0.001 with a significant level of 0.05. In addition, the combined effect size value is 1.46 which means the impact is very large based on Cohen's scale. Meanwhile, when viewed from the perspective of the level of education, there is a big difference in the effect between junior high school and senior high school. With an average effect size value of junior high school of 1.194 while high school is 2.008. If the two are compared, the effect is greater at the senior high school level than junior high school. Therefore, based on this research, the problem-based learning model is considered an effective learning model to improve students' mathematics learning outcomes compared to conventional learning models.

Keywords: problem-based learning model, math learning outcomes, and meta-analysis.
Resource-based view theory and its applications in supply chain management: A systematic literature review
Authors: Komakech Robert Agwot , Ombati Thomas Ogoro , Kikwatha Reuben Wambua , Wainaina Michael Githii
Published: February 2025

This systematic literature review critically examines the application of the Resource-Based View (RBV) theory within Supply Chain Management (SCM) across various industries. Developed by Jay B. Barney in 1991, RBV posits that a firm's sustained competitive advantage is driven by its unique resources and capabilities that are valuable, rare, inimitable, and non-substitutable. RBV suggests that a company’s long-term competitive advantage stems from its distinct resources and capabilities, which are valuable, rare, difficult to imitate, and not easily substitutable. Despite extensive utilization in strategic management, the direct application of RBV in SCM has been less explored, particularly in understanding how specific internal resources enhance SCM capabilities and outcomes. The review adopts a systematic approach, analyzing 97 peer-reviewed articles from diverse journals. This method includes a comprehensive search and evaluation process, ensuring the inclusion of significant studies that discuss the application of RBV in SCM across various industries. The articles were sourced from Scopus databases, with keywords related to RBV and SCM to ensure thorough topic coverage. The findings indicate a pronounced increase in related publications since 2010, reflecting a growing scholarly and practical interest in RBV’s application to SCM. The findings revealed that emerging trends like integrating advanced technologies like Blockchain, Artificial Intelligence and the Internet of Things are identified as strategic resources that redefine competitive landscapes by enhancing transparency, responsiveness and responsiveness within supply chains. The review also highlights the increasing importance of sustainability practices within SCM, aligning with RBV to potentially offer a sustainable competitive advantage. Conclusively, this review contributes to both academic knowledge and guides practitioners toward leveraging internal resources strategically to navigate contemporary challenges, setting a foundation for future inquiries into global supply chain resilience and dynamic capabilities.
