Many retail companies had to go online before their Enterprise Resource Planning (ERP)-type systems were ready to fulfill all business requirements. Their overall daily operation still heavily depends on these highly customized systems often mandatory because of legal obligations, which frequently come without e-commerce “off the shelf” integration. This paper identifies main challenges derived out of the architectural and integration requirements from a case study at an e-tailer company that operates via two sales channels: online store and third-party marketplaces. These challenges led to the definition of a system architecture and implementation considerations for this common integration scenario, which was validated through its implementation. Our proposed approach allows ERP-dependent organizations to start selling online with open-source technologies, avoiding extra ERP licensing and hidden maintenance costs.

As relações familiares podem influenciar o desenvolvimento da anorexia nervosa, precipitando-a. Também é reconhecido o papel mantenedor e resiliente da família sobre o transtorno. Este artigo teórico tem o objetivo de discutir a influência do relacionamento familiar sobre o desenvolvimento da anorexia nervosa. Foi realizada uma pesquisa bibliográfica sobre o respectivo tema, utilizando as bases de dados Scielo Brasil e Periódicos Capes para compor a maior parte do corpus deste trabalho. A influência familiar negativa sofrida pelo membro, que pode favorecer o surgimento e manutenção da anorexia, alude às falhas na comunicação; a rigidez nos padrões interacionais; o pouco recebimento de afeto; a liberdade para expressar afetos, sentimentos e emoções; a cristalização e não resolução de conflitos; e as dificuldades para lidar com determinados sentimentos e emoções.

The Covid-19 pandemic has the entire world in agony, and Brazil is one of the countries being hit the hardest. This article analyzes a pandemic-related decision made by the Brazilian Ministry of Health in August 2020, when it rejected Pfizer’s proposal to acquire 70 million doses of the Pfizer/BioNTech vaccine. The question we ask is this: of the Brazilians aged 80 or older who died of Covid-19 in Brazil in March 2021, how many would still be alive if the Ministry of Health had acquired the 70 million doses of the Pfizer/BioNTech vaccine in August 2020?

The Covid-19 pandemic has the entire world in agony, and Brazil is one of the countries being hit the hardest. This is the S econd Article in the series that analyzes a pandemic-related decision made by the Brazilian Ministry of Health in August 2020, when it rejected Pfizer’s proposal to acquire 70 million doses of the Pfizer/BioNTech vaccine. The question we ask is this: of the Brazilians aged 70 or older who die d of Covid-19 in Brazil in April 2021, how many would still be alive if the Ministry of Health had acquired the 70 million doses of the Pfizer/BioNTech vaccine in August 2020?

This article analyses the dilemas faced by the Cuban revolution, as the commodification of social relations clashes with a relative consensus around the preservation of social accomplishments and national sovereignty associated to the revolution.

Abstract Belo Horizonte, capital of Minas Gerais state, is a highly urbanized city located in the third largest metropolitan area of Brazil, being one of the most important cities in the country. There are several potential air pollutant emission sources in the studied area, such as industry and the vehicular fleet (1,669,884 vehicles in 2015). These can affect the air quality, which can have an impact on population health. Despite this critical scenario, few studies have been developed with the objective of evaluating the air quality in this city, especially regarding the identification of pollutant emission sources. Thus, the aim of this study was to identify and quantify atmospheric emissions by stationary sources of significant environmental impact in Belo Horizonte. The quantification of emissions was preferably performed based on chimneys monitoring data. However, in the absence of these data, estimates were made based on AP-42 guidelines. As a result, 75 chimneys were identified, belonging to 28 companies. Pollutant emission rates of 305, 235, 234, 224, 206, 180 and 63 t year-1 were observed for NOX, CO, TSP, PM10, PM2.5, SO2 and VOC, respectively. The results obtained can contribute to the diagnosis, modeling and management of air quality in Belo Horizonte.

This article examines the dual nature of the impact of Artificial Intelligence on higher education, seeking to understand whether it enhances or undermines student development. On the one hand, AI offers added value by streamlining tasks and promoting critical thinking through personalised support. However, according to Carr (2010), there is a real risk of ‘cognitive substitution’ and dependency if intellectual effort is neglected, undermining academic integrity and autonomy, a risk exacerbated by the ‘hallucinations’ (Ji et al, 2023). It can be concluded that the impact of AI is not solely about the technology itself, but rather how students use it. The key to the effective use of these tools lies in changing assessment methods, focusing on critical and ethical reflection, to ensure that the student’s education and development are not compromised as a future professional.  

Numa wordnet, conceitos são representados através de grupos de palavras, vulgarmente chamados de synsets, e cada pertença de uma palavra a um synset representa um diferente sentido dessa mesma palavra. Mas como os sentidos são entidades complexas, sem fronteiras bem definidas, para lidar com eles de forma menos artificial, sugerimos que synsets sejam tratados como conjuntos difusos, em que cada palavra tem um grau de pertença, associado à confiança que existe na utilização de cada palavra para transmitir o conceito que emerge do synset. Propomos então uma abordagem automática para descobrir um conjunto de synsets difusos a partir de uma rede de sinónimos, idealmente redundante, por ser extraída a partir de várias fontes, e o mais abrangentes possível. Um dos princípios é que, em quantos mais recursos duas palavras forem consideradas sinónimos, maior confiança haverá na equivalência de pelo menos um dos seus sentidos. A abordagem proposta foi aplicada a uma rede extraída a partir de três dicionários do português e resultou num novo conjunto de synsets para esta língua, em que as palavras têm pertenças difusas, ou seja, fuzzy synsets. Para além de apresentar a abordagem e a ilustrar com alguns resultados obtidos, baseamo-nos em três avaliações -- comparação com um tesauro criado manualmente para o português; comparação com uma abordagem anterior com o mesmo objetivo; e avaliação manual -- para confirmar que os resultados são positivos, e poderão no futuro ser expandidos através da exploração de outras fontes de sinónimos.
