Futures studies offer a framework of ideas and guidelines that allow us to develop more productive images of the future and ways of working with it. Despite several efforts to translate this approach to different educational contexts, it is still a field under development. The main objective of this article is to present and discuss the latest international academic developments and contributions of futures studies to education. For this purpose, we conducted a systematic review of the literature using the Web of Science and Scopus databases. We considered articles published between 2012 and 2022. We started with 437 articles and after the application of the exclusion criteria, this number was reduced to 50 articles that were directly related to educational issues. The findings show that the literature included specific educational methodologies, a balance between theoretical and empirical publications, a focus on specialised journals and countries and that multidisciplinarity in education was not common with subjects outside social sciences. Moreover, we found that the predictive approach and negative perspectives were not present. We conclude that futures literacy is a key element to bringing together ideas related to futures studies in education, that futures studies contribute to changing the way of working with and conceptualising the future in education, and that they promote transformative movements.

Objetivo. Analizar la existencia y actualización de las listas de medicamentos nacionales (LMN) y guías de práctica clínica (GPC) para el tratamiento de la diabetes en América Latina y el Caribe (ALC). Comparar los fármacos incluidos en las listas y guías de cada país, entre sí y con los de la Organización Mundial de la Salud (OMS). Métodos. Estudio de corte transversal. Se identificaron las LMN y GPC para diabetes en los sitios web de la Organización Panamericana de la Salud y de las autoridades sanitarias nacionales. Se relevaron los fármacos y se analizaron por grupo farmacológico según el cuarto nivel de la nomenclatura ATC. Se utilizó el puntaje F1 para evaluar la proximidad de las LMN con la lista modelo de medicamentos esenciales (LMME) de la OMS. Resultados. Del total de países, 87,2% cuentan con LMN, y 91% con GPC (78% y 45% actualizadas en los últimos 5 años, respectivamente). En comparación con los 6 grupos de hipoglucemiantes de la LMME, las LMN tenían una mediana (rango) de 6 (4-13) y un puntaje F1 de 0,80; esto indica una consonancia adecuada. Las GPC tenían una mediana (rango) de 12 (1-12) hipoglucemiantes frente a los 8 de las guías de la OMS. Las GPC tuvieron una mediana de 15 fármacos más que las respectivas LMN. Conclusiones. Si bien la mayoría de los países de ALC cuentan con LMN y GPC para diabetes, la falta de concordancia entre ellas limita su eficacia. Es necesario alinear los procesos y criterios de elaboración de estas dos herramientas de la política de medicamentos.

El presente artículo indaga la conflictiva relación entre los lineamientos programáticos de la intelligentsia revolucionaria y las aspiraciones de las masas populares en el marco del proceso revolucionario ruso de 1917. Los primeros abogaban por una ruptura radical con el pasado autocrático y una redefinición de los fundamentos de la sociedad futura a partir de un poder centralizado. Se trataba de un denominador común para concepciones tan disímiles como el anarco-biocosmismo y el socialismo bolchevique. Las bases movilizadas, en cambio, pretendieron operar una redefinición revolucionaria de la lógica inmanente al viejo sistema, antes que su total destrucción. Argumentaremos que es posible comprender tanto el trasfondo ideológico que unificaba la perspectiva emancipatoria de anarquistas-biocosmistas y bolcheviques, como la divergencia entre estas visiones y las aspiraciones de los restantes sectores subalternos, dado el análisis de la dinámica propia de la estructura estamental de la Rusia zarista tardía. Destacaremos que el posicionamiento externo que respecto de dicha estructura asumió la intelectualidad revolucionaria, en contraste con la modalidad de integración que en ella adoptaron las bases trabajadoras, puede brindar una clave interpretativa en el momento de analizar la contraposición de perspectivas entre ambas fracciones del movimiento revolucionario.

Calculus courses have been attracting the attention of mathematics education researchers over the last decades. Recent publications and special issues dedicated to calculus highlight the diverse roles of calculus courses in the pathways for STEM studies within and across educational levels, as well as issues related to the academic preparation of future STEM professionals, including mathematicians, non-mathematics professionals (NMPs) and teachers. In this paper, we review recent literature, mostly since 2015, to identify and characterize explicit references to such diverse roles of calculus courses. The review highlights an intrinsic tension between two institutional roles of calculus: "scaffolding" and "filtering." We find nuanced yet substantial variation in how the dual role of calculus is experienced and managed across different groups of students and stakeholders. With regard studies on calculus for mathematics students, recent studies attend to changes in the rules underpinning calculus notions and processes, and highlight the scaffolding potential of calculus courses towards abstraction and reasoning. In contrast, studies on calculus for NMPs report that such courses often promote filtering rather than scaffolding and question transferability and relevance of those courses for NMPs. Finally, studies challenge the perception that traditional tertiary calculus courses scaffold school teaching and underline the need for empirical research that would explain the nature of this scaffolding and how it can be realized in practice. We conclude that further empirical research, in particular theory development, is needed to address the diverse roles of calculus at the intersection of institutions, disciplines and communities.

Of the many disciplines that rely on calculus, physics is among those with the strongest connections to this branch of mathematics. For instance, the derivative--one of the key notions of calculus--is used to describe velocity and acceleration, which play a central role in mechanics. In post-secondary education, in particular at the college level, it is not unusual for students to enroll in calculus and mechanics courses in the same year, and even the same term. In mathematics education, however, there is scant research focusing on students' construction of the notion of derivative in a mechanics context, and existing studies offer contradictory views on the effectiveness of using mechanics to teach derivatives. To shed light on the use of derivatives in mechanics and calculus courses, our study focuses on practices involving the use of derivatives to study motion in both courses. We first conducted a praxeological analysis of five differential calculus textbooks and five mechanics textbooks to pinpoint their use of derivatives in the study of motion. This analysis was complemented by interviews with four mathematics teachers and three mechanics teachers, to compare their praxeologies with those of the textbooks. We then identified consistencies and inconsistencies between practices employed in both courses, which may have an impact on students' learning, and formulated recommendations for teaching the notion of derivative in kinematics.

BackgroundStudies have suggested that children are less likely than adults to develop COVID-19; however, with the emergence of SARS-CoV-2 variants, hospitalization and death due to this cause have increased among the youngest ones.MethodsRetrospective, descriptive analytical study of the COVID-19 cases, hospitalizations and deaths occurred in children under five years who attended in Child Day-Care Centers (Centros de Atención Infantil-CAIs) of the Mexican Social Security Institute (IMSS) from 20th July 2020 to 31st March 2023. Results were compared with Mexico's and the US's national-level data. Incidence, attack (children and workers) and mortality rates were estimated. The risks of getting sick, being hospitalized and dying due to COVID-19 were calculated by year.ResultsThere were 4,369 COVID-19 cases among children from IMSS CAIs; 67 (1.5%) required hospitalization and only two deaths were reported (0.04%). Both at IMSS CAIs and at a national level in Mexico and the US, the highest incidences of COVID-19 among children under five years occurred during Omicron prevalence. The attack rate among workers (32.93%) was higher than children (4.99%). Hospitalization and mortality rates in the US decreased since the anti-COVID 19 vaccine was introduced in children older than six months, unlike the rates in Mexico, where the vaccine for this age group was not available. By the year 2020, the children that attended the IMSS CAIs were 77.3% less likely to be hospitalized; 80.9% in 2021, 93.2% in 2022, and 77.7% by March 2023, compared to same age children in Mexico. In 2021, the children that attended IMSS CAIs were 90.6% less likely to die due to COVID-19, and by March 2023, this likelihood was 34.3% lower than the rest of children in this age group in Mexico.ConclusionsChildren that attended IMSS CAIs had a smaller risk of hospitalization and death due to COVID-19. However, the high rates of hospitalization and death due to SARS-CoV-2 in children under five years in our country point to the need and urgency of vaccination against this virus in this age group, as well as of the adherence to strict detection and medical referral protocols.

Abstract As a result of human activities and natural dispersal, exotic species can be brought to new areas, where they become established and spread, becoming invaders. These species are responsible for the loss of biodiversity and cause ecosystemic harm throughout the world. In this paper, we report the rapid, broad geographic expansion of the invasive fly Drosophila nasuta in Brazil. An 84% increase was found in its area of occupation in the country compared to previous studies. The present data reveal its arrival to the Pantanal wetlands in a location more than one thousand kilometers from the closest previous record in the Cerrado biome. We present the first record of D. nasuta in the Atlantic Forest in the states of Paraíba and Bahia. We report its introduction in the Amazon Forest in the state of Amazonas approximately 700 kilometers from previous records. The relative abundance of D. nasuta in this biome increased fivefold in comparison to a previous study. In the first decade of invasion in Brazil, D. nasuta has already colonized more than half of the country. The present data reveal its invasive potential and underscore the importance of following up the possible negative effects of this biological invasion.

Assessing the impact of climate change is essential for developing water resource management plans, especially in areas facing severe issues regarding ecosystem service degradation. This study assessed the effects of climate change on the hydrological balance using the SWAT (Soil and Water Assessment Tool) hydrological model in the Mixteco River Basin (MRB), Oaxaca, Mexico. Temperature and precipitation were predicted with the projections of global climate models (GCMs) from the Coupled Model Intercomparison Project Phase 6 (CMIP6); the bias was corrected using CMhyd software, and then the best performing GCM was selected for use in the SWAT model. According to the GCM MPI-ESM1-2-LR, precipitation might decrease by between 83.71 mm and 225.83 mm, while temperature might increase by between 2.57 °C and 4.77 °C, causing a greater atmospheric evaporation demand that might modify the hydrological balance of the MRB. Water yield might decrease by 47.40% and 61.01% under the climate scenarios SP245 and SSP585, respectively. Therefore, adaptation and mitigation measures are needed to offset the adverse impact of climate change in the MRB.

Calculus is a required course in most engineering programmes and is intended to provide students with tools they will use throughout the rest of their training. However, research seems to indicate that calculus is not very prevalent in the engineering workplace or in university engineering courses. To shed some light on how calculus is actually used in engineering programmes, we analysed two courses (Strength of Materials and Electricity and Magnetism) to examine their use of integrals. We first conducted a praxeological analysis examining the introduction of two topics (bending moments and electric potential) in the courses' textbooks before interviewing the teachers of each course to compare their praxeologies with those of the books. Our results show that integrals are used to introduce engineering notions in both courses, with praxeologies that combine elements from mathematics and engineering but that do not call upon calculus techniques to any great extent. Moreover, integrals do not factor highly in students' assessments in either course, which implies that students may pass these courses without any knowledge of integrals as taught in their calculus courses.

Introduction- The knowledge of the weeds present in the agroecosystems and their populations allows to project in a more accurate way the management programs of these. Objective-. Characterize the diversity of weed species and its coverage in 120 small farms of small farmers in the municipalities of Boyacá. Methodology-. The investigation was carried out in 15 farms in the municipalities of the Department: Chitaraque, Gachantivá, La Capilla, Nuevo Colón, Maripí, Santa Maria, Zetraquira and Tuta, in each of 0.5 ha plots where the landmarks were determined. of 1m2 the weeds present and the percentage of coverage. Results-. It was observed the presence of 255 species of weeds located in 167 genera and in 60 botanical families, being the most representative families Asteraceae and Poaceae, followed by Cyperacea, Fabaceae and Polygonaceae. The municipalities characterized by a higher relative temperature Chitaraque, Santa María and La Capilla present higher specific richness. The species with the highest frequency, present in all the municipalities was P aquilinum, in 75% of the municipalities were D. ciliata, and S. rhombifolia and in 62.5% Anthoxanthum odoratum, Bidens pilosa, Desmodium incanum, Hypochaeris radicata and Verbena litoralis. Conclusions-. From the monocotyledons, several species of Poaceas stood out with greater coverage, among them; C. clandestinum, three from the Brachiaria genus, three from Cynodon, within the Cyperaceae the species Dichromena ciliata, and one fern from the Dennstaedtiaceae family, P. aquilinum, which generally constitute important weeds of economic crops.

In a globalized and media society with unprecedented technological development, institutions of higher education are adapting their training models to face this new challenge. This study aimed to determine students' self-perception of their media competence and the differential influence of an ecosystemic model of training that is being implemented experimentally. The research methodology is mixed, as both a quantitative (descriptive and inferential analysis) as well as a qualitative analysis (are made of the contents of the open reports). A total of 808 university students enrolled in the 2015-16 course in different university centres and countries (Faculty of Teacher Training and Education, and Faculty of Economics-Business of University of Oviedo (Spain) and Technological Institute of Mexico), completed a questionnaire about media competence and wrote open reports about their experience with ecosystemic models. The results showed that university students have a favorable self-perception of their level of media competence, and they consider it important to develop by means of transversal training and ecosystemic training models. Significant differences between the students of the different degrees also emerged depending on whether or not an ecosystemic approach was used to develop the subjects. In conclusion, the study shows that these models favor teaching-learning processes in the university by adapting the technology to the users and improving their media competence.
