This article analyzes and develops a method to solve fractional ordinary differential equations using the Monte Carlo Method. A numerical simulation is performed for some differential equations, comparing the results with what exists in the mathematical literature. The Python language is used to create computational models., Comment: Text in portuguese. Accepted for publication in Trends in Computational and Applied Mathematics

Mental health is an essential component for students' overall development and for creating a healthy and productive school environment. This paper reviews the literature on mental health in schools, highlighting the importance of psychopedagogical interventions. Key risk and protective factors are discussed, along with intervention strategies that can be implemented in the school context. It is concluded that an integrated approach, involving collaboration among educators, psychopedagogues, families, and the community, is fundamental for promoting mental health and academic success for students.

Toxic behavior is one of the problems most associated with the gaming community. Reports of hate speech and anti-gaming behavior are common in many online multiplayer games. Many studies address this area, focusing on players and, principally, on the content and its negative impact on the community. However, it is possible that other factors influence the toxicity. In this article, we investigate how game design elements influence toxic behavior, using toxic disinhibition factors as a basis for the analysis. For this, four of the main games of the MOBA genre were analyzed with the support of the MDA Framework and a questionnaire with players. The results show that most players suffered offenses and offended other people in the game, in addition to recognizing MOBA as the genre that generates the most impatience among them. Furthermore, we raise and discuss different elements and mechanics in games that impact the well-being of the community through the individualization of the player, elimination of solidarities, and affirmation of indifference towards toxic behavior. With this, we hope to help game developers and communities to promote integration dynamics., Comment: 10 pages, 11 Figures Proceedings of the XIX Brazilian Symposium on Games and Digital Entertainment Recife, Brazil.

Quantum information processing has been one of the pillars of the new information age. In this sense, the control and processing of quantum information plays a fundamental role, and computers capable of manipulating such information have become a reality. In this article we didactically present basic elements of the latest version of IBM's quantum computer and its main tools. We also present in detail the Deutsch-Jozsa algorithm used to differentiate constant functions from balanced functions, also, including a discussion of its efficiency against classical algorithms for the same task. The experimental implementation of the algorithm in a 4-qbit system is presented. Our article paves the way for a series of didactic investigations into the IBM system as well as the best known quantum algorithms., Comment: in Portuguese

Whereas the world relies on computer systems for providing public services, there is a lack of academic work that systematically assess the security of government systems. To partially fill this gap, we conducted a security evaluation of publicly available systems from public institutions. We revisited OWASP top-10 and identified multiple vulnerabilities in deployed services by scanning public government networks. Overall, the unprotected services found have inadequate security level, which must be properly discussed and addressed., Comment: in Portuguese

This note discusses some aspects of interpretations of the theory of optimal taxation presented in recent works on the Brazilian tax system., Comment: in Portuguese

The 2022 Commitment to Reducing Inequality (CRI) Index is the first detailed analysis published looking at governments’ policies and actions to fight inequality during the first two years of the pandemic. This fourth edition of the CRI Index reviews the spending, tax and labour policies and actions of 161 governments during 2020–2022., COVID-19 has increased inequality worldwide, as the poorest people were hit hardest by both the disease and its profound economic impacts. Yet the CRI 2022 Index shows clearly that most of the world’s governments failed to mitigate this dangerous rise in inequality. Despite the biggest global health emergency in a century, half of low-and lower-middle-income countries saw the share of health spending fall during the pandemic, half of the countries tracked by the CRI Index cut the share of social protection spending, 70% cut the share of education spending, while two-thirds of countries failed to increase their minimum wage in line with gross domestic product (GDP). Ninety-five percent of countries failed to increase taxation of the richest people and corporations. At the same time, a small group of governments from across the world bucked this trend, taking clear actions to combat inequality, putting the rest of the world to shame., See also the CRI Index website: www.inequalityindex.orgThe Index has been audited by the European Commission's Joint Research Centre.

Cette analyse passe en revue les politiques et actions de 161 gouvernements en matière de dépenses, de fiscalité et de travail sur la période 2020-2022., La COVID-19 a creusé les inégalités dans le monde entier, les plus pauvres étant les plus durement touché·es par la maladie et ses profondes répercussions économiques. Pourtant, l’indice ERI 2022 montre clairement que la plupart des gouvernements du monde n’ont pas réussi à atténuer cette dangereuse augmentation des inégalités. Alors qu’il s’agit de la pire urgence sanitaire que le monde ait connue depuis un siècle, la moitié des pays à revenu faible et intermédiaire de la tranche inférieure ont vu la part des dépenses de santé diminuer pendant la pandémie. La moitié des pays suivis par l’indice ERI ont réduit la part des dépenses de protection sociale, 70 % ont revu à la baisse la part des dépenses d’éducation, tandis que deux tiers des pays n’ont pas augmenté leur salaire minimum en fonction du produit intérieur brut (PIB). 95 % des pays n’ont pas augmenté l’imposition des personnes et des sociétés les plus riches. Dans le même temps, quelques gouvernements dans différentes parties du monde se sont démarqués de cette tendance en prenant des mesures claires pour lutter contre les inégalités, couvrant de honte le reste du monde.

The Transformative Leadership for Women’s Rights working group of Oxfam International is proud to present a new Global Program Framework. The Framework was developed to help us deliver our strategic ambition on Transformative Leadership for Women’s Rights (TLWR). This Framework has been developed both to support colleagues wanting to integrate TLWR principles and approaches into programs and campaigns, as well as those developing stand-alone Gender Justice programs in support of TLWR. It is not intended to be the ‘rulebook’ for how Oxfam designs programs but rather what we hope will be a valuable guide and practical prompt for colleagues and partners seeking to start out or mature their program approach in this important area.
