Este ensayo reflexiona sobre la representación de la figura del inmigrante subsahariano y del tránsito migratorio entre África y España en el imaginario colectivo español de la última década. Se analiza desde una perspectiva crítica la película Adú (Salvador Calvo, 2020) como ejemplo de contribución cultural que se enmarca en el discurso hegemónico de la representación de la otredad en el contexto español. En contraposición, se propone un estudio comparativo con relatos testimoniales que sirven de contraargumentación al discurso hegemónico: el texto Partir para contar: un clandestino africano rumbo a Europa (Pepitas de Calabaza, 2014) y el documental Samba, un nombre borrado (Mariano Agudo, 2017), ambos vinculados a la experiencia de Mahmud Traoré, un joven senegalés que llegó a Europa en 2005 tras saltar la valla de Ceuta. Estos relatos, ofrecen una representación alternativa de la experiencia migratoria que cuestiona el discurso oficial y se configuran como un caso paradigmático que rechaza el mensaje disuasorio predominante en los medios de comunicación y en los productos culturales para el público de masas, revirtiendo los códigos de representación basados en la victimización de los migrantes.

El autor recuerda que sus primeras experiencias radiofónicas tuvieron lugar en la emisora universitaria que inauguró la radiofonía de esa matriz. Desde siempre la radio académica de la UNLP tuvo el propósito de ampliar el repertorio que muchas estaciones, incluso hoy, anclan al rito totalizador y excluyente de la actualidad rabiosa. El artículo reivindica el espacio de los medios universitarios ofrecen para escudriñar el pasado, observar el presente e imaginar el porvenir desde una miríada de perspectivas que involucran tanto a las ciencias duras, como a las sociales; a las humanidades y a una variedad de disciplinas artísticas. Sobre todo en circunstancias como las que vive hoy la Argentina ese aporte es necesario para que los futuros posibles puedan llegar a ser futuros deseables. Con ese propósito es imprescindible concebir un estatuto productivo que favorezca el desarrollo cognitivo, emocional y creativo de las audiencias.

Los desplazamientos forzosos provocados por causas medioambientales se están incrementando en los últimos años. Muchas de las personas que migran por estas razones son expulsadas de sus tierras por el cambio climático lo que conlleva efectos sociopolíticos que provocan a su vez conflictos armados. Esto genera un grupo cada vez más numeroso de migrantes que puede provocar la próxima “crisis de personas refugiadas”. Ante esta situación, será fundamental brindarles asistencia y protección. ¿Qué marco teórico podría fundamentar la aplicación de la legislación internacional y de las políticas migratorias europeas a la protección de las personas desplazadas forzosamente por causas medioambientales? La respuesta podría estar en la mirada del enfoque interseccional en relación con la dinámica de nexos formulada por ACNUR, ambas generan nuevos diálogos que deben avanzar hacia futuras regulaciones de movilidad humana en el siglo XXI.

The transformation process that the educational system in Mozambique is undergoing is aimed at complying with the sustainable development goals declared at a universal level. The human and social progress achieved highlights the challenge that educational attention to diversity implies in the context of the inclusive school. The actions developed led to the analysis of the foundations that support the objective of proposing a pedagogical conception for intersectoral work in educational attention to school diversity in Mozambique. The research methods used followed a descriptive-explanatory approach, supported by theoretical level methods, including historical-logical, analysis and synthesis, induction and deduction, structural-functional systemic and modeling; in addition to methods of the empirical level, such as documentary analysis, observation, interview, evaluation by expert criteria and the methodological triangulation technique, as well as the procedures of descriptive statistics based on the calculation of the index and inferential statistics for performing hypothesis tests; those that allowed to analyze, interpret and process the information related to the object of investigation, highlighting the role of intersectorality in the educational field as a social need. The pedagogical conception, with an intersectoral approach, reveals the participation of various government agencies and institutions in achieving quality educational care. The results obtained confirmed the need to treat aspects related to intersectorality.

The business world is constantly changing and managers have had to face various challenges to adapt to a new reality. Among these: managing research and development for tangible and intangible products, complying with strict biosafety standards, digitalizing processes, reordering interrelationships, retaining personnel, formulating commercial strategies and adapting to new market variables. But it is strange that they have not committed themselves to the transformation from the reconstruction of their axiological burdens. Since the axiological component is present in people as they are the ones who give life to organizations, human values are the moderators of managerial praxis to create competence. Therefore, the objective of this paper is to offer a descriptive review of a selection of major challenges to be assumed by the manager, in nominal categorical terms of ontological, axiological, autopoietic and complex processes, in order to formulate strategies focused on being and doing. The methodology starts from the neodialectical approach, considering an exegetic, free and reflexive criterion of argumentative construction, to unveil within these general spheres of interest the main reflection in which, the increase of people's competence in turbulent and highly uncertain business environments, has its most solid teleology in the corporate axiopoietic.

Man, by his very nature, seeks different means of social interaction throughout his life. Recently, the growing number of users of the TikTok application has not gone unnoticed by the Church, which sees everything as an opportunity to evangelize. For each new generation it is the mission of the Church to transmit the gospel to new people who come into this world. In the current context, younger generations are increasingly connected on social networks and, after the 2020 pandemic, many young people joined the use of the TikTok app as a means of personal entertainment and social interaction to alleviate the tensions generated by the atypical situation of widespread isolation. Although TikTok was not created as a means of evangelization, but as a means of entertainment, it is up to the Church to overcome this real challenge and manage with its fruitful creativity to transmit its message in these new places where people are, needing to know better their potential and limitations, as well as avoiding possible dangers that new technologies may present. To this end, certain principles and guidelines already addressed in the Medellín document can help provide clues to this new social communication medium called TikTok. [ABSTRACT FROM AUTHOR]

O engajamento entre grandes empresas e startups, intitulado Corporate Startup Engagement (CSE), é cada vez mais utilizado como estratégia corporativa em processos de inovação aberta. No intuito de contribuir para que o relacionamento entre grandes empresas e startups seja mais assertivo e colaborativo, o artigo visa apresentar parte do trabalho de pesquisa realizado no Programa de Mestrado Profnit, que teve como objetivo o desenvolvimento de uma ferramenta visual para a sistematização de desafios corporativos em interações de baixa maturidade com startups. Acredita-se que a sistematização das principais informações que devem estar disponíveis num desafio corporativo, tanto para compartilhá-lo com o ambiente externo – startup, programas, editais etc. – como no ambiente interno, é importante para a melhoria das interações. Utilizou-se a metodologia do Duplo Diamante, com a aplicação de métodos e ferramentas de gestão e design, para elaborar a ferramenta visual que foi testada e validada em um workshop. Concluiu-se que abordagens que possibilitem o levantamento e o registro sistematizado de desafios corporativos, utilizando-se de ferramentas visuais, podem colaborar para ampliar as taxas de sucesso no engajamento entre grandes empresas e startups.

The social, economic and cultural changes in recent years have caused new demands and readjustments in people's lives and behaviors, bringing as consequences negative reactions such as prolonged stress and rumination that facilitates getting hooked on issues and mistakes made. For all this, having instruments that operationalize these variables will give way to having current, reliable and accurate measurements. We worked with a convenience sampling made up of 388 people, aged between 17 and 62 years. As a result, the confirmatory factor analysis showed a total Alpha of .823 with two factors (Control and Uncontrol) for the Stress scale. For the Rumination scale, a total Alpha of .914 was found with two factors as well (Discomfort and Obsessive reflection). Regarding the correlations, associations were found between the factors of Stress with Rumination. Similarly, it was possible to develop two valid and reliable scales to evaluate the exposed scales.

Las tareas matemáticas de alta demanda cognitiva implican ejercer habilidades para analizar, inferir, relacionar y reflexionar sobre la información aritmética, geométrica y estadística. En su desarrollo, el compromiso del estudiantado es crucial para superar situaciones cada vez más complejas en el proceso de aprendizaje del sistema escolar peruano. Estas variables son de vital importancia, debido a que el estudiantado necesita evitar influencias negativas que provoquen el fracaso o la deserción académica, por lo que es valioso vivir experiencias de mejora motivacional de su conducta matemática para llegar al éxito permanente en esta área. En esta propuesta, el objetivo fue comprobar, con base en la teoría de Flow (fluencia), si los efectos de una experiencia de provocación por desafíos optimizaban el abordaje de tareas matemáticas con determinada demanda cognitiva. El diseño fue de tipo cuantitativo preexperimental. Se incluyó una muestra de 76 estudiantes. El instrumento fue la prueba de problemas aritméticos con demanda cognitiva múltiple. Los resultados permitieron concluir que el programa estimuló la solución de tareas memorísticas y problemas con información no conectiva, pero su efecto fue menor y más lento en el abordaje de tareas de alta demanda cognitiva. El estudio contribuyó a comprobar las bondades del andamiaje basado en estrategias de fluencia (Flow), de acuerdo con los desafíos y retos que estimulan la independencia cognitiva del estudiantado que aprende a abordar tareas cognitivas, en concordancia con la experticia y compromiso obtenidos mediante la interacción con el personal docente o mediador.

Investigating voter preferences has been a challenge for those studying the politics of fracking. Recent scholarship has assessed local fracking bans in Texas, Ohio, Colorado, and Pennsylvania. These findings suggest the importance of political ideology and voters' experience. This project continues to develop an understanding of local defiance and "fracking" attitudes, by extending this inquiry to California. Utilizing a novel dataset of over 400 voting precincts across three California counties, we find that political ideology, the presence of nearby spills, and education shape voters support for local bans on fracking.

La pedagogía para la Cultura de Paz, Ciudadanía y Derechos Humanos apelando a la Memoria y la Justicia requiere una educación que apunte a la comprensión de los acontecimientos pasados y presentes, al desarrollo del pensamiento crítico, a la adquisición de nuevos métodos de reflexión intelectual y al fortalecimiento de prácticas de acción concreta sobre la realidad. La aplicación de métodos no violentos, una plena participación ciudadana y el reconocimiento a la diversidad y multiculturalidad en el proceso educativo aseguran una construcción armoniosa de aprendizajes que se tornarán duraderos en la vida y la consciencia de todos sus actores. Este artículo intenta demostrar que la educación basada en estos fundamentos se compromete con principios pedagógico-democráticos tendientes a una paulatina transformación social y política de la población y de sus gobiernos. Estamos hablando, por lo tanto, de una educación que desafia las propuestas pedagógicas tradicionales, proponiendo um aprendizaje para la construcción de sociedades más justas, equitativas y solidarisa en el contexto actual del continente latino-americano.

El presente artículo pretende, bajo una concepción bibliográfica y aportes personales, abordar la tensión que existe por parte de los docentes, al momento evaluar los aprendizajes y como se torna este momento en un gran desafío considerando el contexto de la escuela básica en el siglo XXI”. A su vez, realzar la importancia de concebir la enseñanza y el aprendizaje como una práctica reflexiva compartida, en la que todos acaban aprendiendo en una relación de mutuo beneficio.

Esta propuesta didáctica responde a la añeja interrogante ¿cómo educar? Su oferta parte de reconocer la importancia del conflicto en el aula. Lo caracteriza como desafío e incidente crítico. Educar se forja, precisamente, al dialogar, confrontar y convenir sobre lo que es motivo de desasosiego docente. Para orientar el diálogo sobre divergencias, dificultades o desafíos, inicialmente, se enuncian elementos de modelos didácticos: tradicional, escuela nueva, tecnología educativa, escuela crítica, métodos inductivos y constructivistas. Luego, para comprender al desafío al educar, se ofrecen bases metodológicas y otras que argumentan qué entender por sentido común, buen sentido, ciencia, filosofía, sabiduría (Sophía), prudencia (Phrónesis), arte (Techné). Sobre la base de ese racimo de argumentos ofrece pistas para confrontar desafiando ideas, sentimientos y prácticas que permitan llegar al acuerdo, a lo conveniente.

Regarding scenic art, the Portuguese censorship of the XVIII century was divorced from the possible authors and the public, trying to promote a form of spectacle and morals unintelligible to the eyes of both parties. This, when an idea was already certain — the usefulness of dramatic art as a mean of instruction and reaching the theater as a space of expression for a large popular audience. Between the most fragile of the social scale, only the most affluent, with average resources and even those obliged to make specific sacrifices, had the opportunity to attend a performance.

Scientific and medical developments, added to our reality in Colombia, demand the training of professionals consistent with ethical principles and clear theoretical concepts on current regulations that are aimed at respect for human life. The country's current constitutional situation poses a challenge to any professional, beyond the legal or health fields, since fundamental rights such as life and freedom of conscience are being questioned. This paper demonstrates the need and importance of promoting and accessing conscientious objection as a response to the legal landscape of the protection of life in Colombia, which may be an example for other countries in Latin America.

The article is devoted to analysis of hardiness and its components (commitment, control, challenge) among student-athletes and students who do not go in for sports (Russia). The purpose of this study is to explore the peculiarities of the level and structure of the hardiness of student-athletes in comparison with students who are not involved in sports. We hypothesized that students-athletes are hardier, and the structure of their hardiness is different from student-non-athletes. The study involved 152 participants (62 male and 90 female). The sample consisted of subjects aged from 18 to 27 years (average age was 21.8 ± 4.1 years). Maddy's "Hardiness Scale" (adapted by Leontiev and Rasskazova, 2006) and structured interview were used. Mathematical data processing was carried out with nonparametric (φ test) and parametric statistics (t-test). Method of Principle Components (Varimax Normalized) was applied in addition. All students have a high level of hardiness. While, the hardiness is higher in student-athletes due to the components of commitment and control. Factor analysis confirmed the presence of a more distinctly differentiated structure of hardiness in student-athletes. Male student-athletes have the highest level of hardiness. Girls who do not engage in sports have the lowest indicates of hardiness. Female student-athletes and young men who do not engage in sports have the same level of hardiness. [ABSTRACT FROM AUTHOR]

Agroecology-based aquaculture emerges as a particularly interesting production alternative for rural family farmers. In such systems, it is desirable to use means for enhancing the zootechnical performance and improving fish immune responses from natural products. Thus, the present study aimed to evaluate the effect of organic diet supplementation with oregano essential oil, Origanum vulgare, on zootechnical performance, hematological parameters, and resistance to the ectoparasite Ichthyophthirius multifiliis (ich) in silver catfish juveniles, Rhamdia sp. A completely randomized design with five treatments (concentrations 0, 0.5, 1.0, 1.5, and 2.0 g oregano essential oil kg-1 diet) and four replicates was adopted. Groups of 20 silver catfish juveniles (initial weight 12.5 ± 0.5g) were stocked in 20 polyethylene tanks (54 L usable volume) connected to a water recirculation system with individual aeration. The diets were prepared with certified organic ingredients and offered for 89 days in two meals a day. At the end of the experimental period, survival, zootechnical performance, hematological parameters, and fish body composition were evaluated. After the final biometry, an experimental challenge with ich infection was performed. Dietary concentrations of oregano essential oil had no effects on growth, hematology, and body composition of silver catfish juveniles (p > 0.05). Neither was there any influence on the level of infection and accumulated mortality of the fish under challenge with ich. Supplementation with oregano essential oil did not prove to be an effective dietary additive in improving the performance or increasing resistance against ich in silver catfish juveniles. However, in view of the importance of the topic, further studies should be carried out to increase knowledge about the effect of this and other natural additives in silver catfish, including at other stages of development.

Introdução: a criptococose é uma micose sistêmica que possui como agente etiológico o fungo Criptococcus neoformans, nas variedades neoformans (o agente etiológico principal) e gatti. A infecção primária ocorre nos pulmões a partir da inalação do patógeno (via de transmissão inalatória), acometendo principalmente indivíduos imunodeprimidos, podendo se apresentar de maneira assintomática ou sob a forma meningoencefálica (apresentação mais comum) e com acometimento pulmonar (segunda forma mais comum). Relato de caso: o paciente apresentou, inicialmente, queixas neurológicas associadas a um achado incidental de formação cística pulmonar, culminando com posterior achado de calcificação nodular cerebral e suspeita diagnóstica de neoplasia cerebral metastatizada em sítios pulmonares. A suspeita foi descartada após a realização da citologia de líquido biológico e exame anátomo patológico de um nódulo pulmonar que confirmaram o diagnóstico de criptococose. O tratamento foi realizado com Fluconazol por seis meses havendo melhora do quadro radiológico e sintomatológico da doença. Discussão: há relação comprovada entre a criptococose e os excrementos de aves ricos em nitrogênio, principalmente de pombos, que atuam como vetor principal do fungo, e o paciente descrito relata que um mês antes do início das manifestações da doença, esteve em contatos íntimos com as aves. Conclusão: o relato de caso ilustra a incidência da criptococose na população de menor prevalência da doença e revela a importância do diagnóstico clínico correto nesses pacientes, pois ela pode se revelar como um desafio diagnóstico, o que incentiva posteriores estudos para sua melhor compreensão. Palavras chave: criptococose, neoplasia, diagnóstico, desafio. ABSTRACT Introduction: cryptococcosis is a systemic mycosis that has the etiological agent Cryptococcus neoformans, in the varieties neoformans (the main etiological agent) and gatti. Primary infection occurs in the lungs from the inhalation of the pathogen (inhalation transmission route), affecting mainly immunocompromised individuals and may present asymptomatic or meningoencephalic (most common presentation) and pulmonary involvement (second most common form). Case report: the patient initially presented neurological complaints associated with an incidental finding of pulmonary cystic formation, culminating with later finding of cerebral nodular calcification and suspected diagnosis of metastatic cerebral neoplasm in lung sites. The suspicion was discarded after performing the cytology of biological fluid and anatomical pathological examination of a pulmonary nodule that confirmed the diagnosis of cryptococcosis. The treatment was performed with Fluconazole for six months, with an improvement in the radiological and symptomatic picture of the disease. Discussion: there is a proven relationship between cryptococcosis and excrements of birds rich in nitrogen, mainly pigeons, which act as the main vector of the fungus, and the described patient reports that one month before the onset of the disease, he was in intimate contact with the birds. Conclusion: the case report illustrates the incidence of cryptococcosis in the population with the lowest prevalence of the disease and reveals the importance of the correct clinical diagnosis in these patients, because it can be a diagnostic challenge, which encourages further studies for better understanding.
