Abstract The end of World War II marks a set of major transformations in Brazilian social thought. Racial and eugenic theories rapidly lose ground to interpretations of cultural and economic nature. This article examines part of these transformations through the perspectives on Japanese immigration to Brazil by two intellectuals with important parliamentary roles: the psychiatrist-eugenicist Pacheco e Silva and the sociologist Gilberto Freyre. Japanese immigration was the subject of intense debate in the 1930s and 1940s, even prompting restrictive or prohibitive amendments in the 1934 and 1946 constitutions. This study analyzes the parliamentary activities of both intellectuals over this period and demonstrates the influence of their respective social thoughts on their political endeavors. This article also examines the transformations that took place in the 1950s, including shifts in Pacheco e Silva’s thinking, a greater influence of Freyre’s ideas, and a reconfiguration of the role of Japanese immigration in parliamentary discourse. thought nature roles psychiatristeugenicist psychiatrist eugenicist Freyre s 1940s 193 194 constitutions endeavors 1950s Silvas thinking Freyres ideas discourse 19 1

In the Amazon, Euterpe oleracea Mart. (açaí), is part of the identity of traditional communities, and the fruit is integrated into their everyday sociocultural dynamics. Hydrolysis and pyrolysis of residual biomass can be alternatives to yield sugars, ethanol, biochar and bio-oil. The açaí seeds subjected to oxidative pretreatment followed by acid hydrolysis increased cellulose to fermentable sugars (reaching 23.5%) and second-generation ethanol production (17.441 L t−1). Açaí oil (ca. 30%) was extracted using a Soxhlet apparatus (using hexane as solvent) and detected through gas chromatography coupled to mass spectrometry (GC-MS), where acids accounted for 82.43% of the total composition, while alcohols comprised only 13.15%. For pyrolysis, temperatures (500 and 550 °C), time (20 and 30 min), and activation temperature (750 and 800 °C) were evaluated, resulting in yields of ca. 22% for biochar and 30% for bio-oil. For the bio-oil, the main compounds detected by GC-MS were acids (16.3%), aldehydes (13.08%), amides (12.19%), alcohols (6.72%), and phenols (4.64%). The obtained biochar displayed surface area values of 553.7 m2 g−1 and 10% crystallinity, indicating its more amorphous nature.

This study offers a comprehensive analysis of how governance capacities in developing countries respond to the challenges that COVID-19 posed. We established a theoretical framework to delve into the multifaceted nature of governance capacities, exploring two distinct aspects of governance: the Weberian one, which focuses on material and organizational capacities, and the Tocquevillian one, which focuses on coordination and associational capacities. We examined these four governance dimensions to illustrate how these distinct skills influence the effectiveness of governance. Our analysis quantifies the impact of the COVID-19 pandemic using such metrics as confirmed cases and deaths. We employ standard and dynamic panel data methodologies to mitigate potential omitted variable bias. Our research findings indicate that countries with robust governance capacities, as assessed by the Bertelsmann Stiftung's Transformation Governance Index, are better equipped to respond effectively to pandemic crises. By applying several models and rigorous robustness tests, we demonstrate efficient resource utilization, the ability to guide and prioritize decision-making within the government, and commitment to cooperation and coordination with other nations and international organizations are the primary drivers of improved outcomes. Our findings remain robust even when controlling for relevant variables and employing estimation techniques that account for potential biases arising from unobservable confounding factors.

This paper elucidates the inseparable connection between the pursuit of a more ecologically sustainable society and the quest for socioeconomic justice. It also demonstrates why Unconditional Basic Income (UBI) is an effective policy to act on both fronts. First, the corresponding theory on environmental and socioeconomic oppression sheds light on the argument that both types of domination stem from the same historical process and are inherently interconnected. Addressing one without considering the other is essentially flawed; they are both features and consequences of present society. Acknowledging the historical debt owed to vulnerable economic classes and developing countries is imperative. Green republicanism could potentially establish a theoretical foundation for social-ecological thinking. Defining freedom as non-domination and applying this concept to nature are essential prerequisites for overcoming socioeconomic and environmental oppression. UBI is presented and discussed theoretically as a strong solution to address these two challenges. It serves not only as a means to facilitate the transition to a post-productivist society, transforming labor relations, but also as a catalyst for the development of circular economies and more sustainable occupations. Additionally, the basic income policy implemented in the city of Maricá, Brazil, is cited as empirical evidence showcasing the environmental and socioeconomic values of UBI. justice (UBI fronts First interconnected flawed imperative socialecological social ecological thinking nondomination non challenges postproductivist post productivist relations occupations Additionally Maricá Brazil

The antifouling booster biocides are frequently studied for toxic effects on the aquatic ecosystems. The present investigation proposes passive silicone rubber samplers as a collection method for biocides, once these methods can concentrate substances in aqueous matrices at very low levels. Through the passive sampler-water partition coefficient (Ksw) and the analyte chemical nature, we can optimize their extraction from the membrane to apply in the sample medium. We used the co-solvent method to determine the Ksw of three third-generation antifouling biocides, chlorothalonil, dichlofluanid, and dichlorooctylisothiazolinone (DCOIT), with log Ksw = 2.24, 4.01, and 2.38, respectively. Improving extraction also led to a recovery range higher than 70%, determinations were carried out by gas chromatography with an electron capture detector. Biocides concentration in seawater samples from Itaqui port (São Marcos Bay, northern Brazil) ranged from 0.058 to 0.72 µg L-1 for chlorothalonil, 0.001 to 0.008 µg L-1 for dichlofluanid, and 0.018 to 0.64 µg L-1 for DCOIT. ecosystems levels samplerwater sampler water (Ksw nature medium cosolvent co solvent thirdgeneration third generation chlorothalonil dichlofluanid DCOIT, DCOIT , (DCOIT) 224 2 24 2.24 401 4 01 4.01 238 38 2.38 respectively 70 70% detector São Bay Brazil 0058 0 058 0.05 072 72 0.7 L1 L 1 L- 0001 001 0.00 0008 008 0018 018 0.01 064 64 0.6 (DCOIT 22 2.2 40 4.0 23 3 2.3 7 005 05 0.0 07 0. 000 00 06 6 2. 4.

Coumarin derivatives possess diverse biological activities, encompassing antibacterial, antifungal, anticancer, antidiabetic, anti-inflammatory, and antioxidant effects. This study concentrates on the synthesis of two new coumarins: the first derived from rhizomes of Luvunga scandens and the second from 7-(diethylamino)-4-methyl-2H-chromen-2-one via bromination facilitated by NBS (N-bromosuccinimide) reagent. Their antibacterial and anticancer properties were evaluated in vitro, alongside in silico docking targeting the chromen-2-one group. Bromination of compound 1 yielded novel compound 2, while compound 4 was efficiently synthesized from 7-(diethylamino)-4-methyl-2H-chromen-2-one (3) using NBS. Testing on lung, breast, and liver cancer cell lines indicated that compound 2 effectively inhibited Staphylococcus aureus and Bacillus cereus at concentrations of 13.20 and 6.6 µM, respectively. It also demonstrated significant inhibition against MCF-7 breast cancer cells with a half-maximal inhibitory concentration (IC50) value of 50.37 ± 3.70 µM. Molecular docking revealed compound 2’s interaction with 2VF5 enzyme, elucidating its bacterial inhibition mechanism, with Gibbs energy and inhibition constant values of -7.42 kcal mol-1 and 3.62 µM, respectively. Additionally, compound 2 exhibited anticancer activity via alignment with topoisomerase 1 (3TOP): 1T8I, supported by molecular dynamics simulations illustrating strong ligand interactions.

Abstract The text explores the relevance of counterfactual history in the academic field, highlighting its usefulness in historical interpretation. Quentin Deluermoz and Pierre Singaravélou, in their work A Past of Possibilities: A History of What Could Have Been (2016), argue that this approach, far from being mere speculation, offers a moral and political dimension by enabling reflection on what might have been. Counterfactual history is taken as an exercise in imagination and experimentation which is crucial for understanding the past. As exemplified in literature and media, this perspective invites consideration of alternative futures, thus enriching the historical narrative. This orientation challenges the traditional perception of history, emphasizing its contingent nature and broadening the understanding of past events.

Resumen El texto explora la relevancia de la historia contrafactual en el ámbito académico, destacando su utilidad en la interpretación histórica. Quentin Deluermoz y Pierre Singaravélou, en su obra A Past of Possibilities: A History of What Could Have Been (2016), argumentan que este enfoque, lejos de ser mera especulación, ofrece una dimensión moral y política al permitir reflexionar sobre lo que pudo haber sido. La historia contrafactual se entiende como un ejercicio de imaginación y experimentación vital para comprender el pasado. Ejemplificada en la literatura y medios, esta perspectiva invita a considerar futuros alternativos, enriqueciendo así la narrativa histórica. Esta orientación desafía la percepción tradicional de la historia, subrayando su naturaleza contingente y ampliando la comprensión de los eventos pasados.

RESUMEN En este trabajo busco aproximarme a una historia in-finita de la naturaleza en el pensamiento-en-imagen de Paul Klee a partir de una interpretación de los parágrafos 76 y 77 de la Crítica de la facultad de Juzgar de Kant. Para su lectura, propongo considerar como contrapunto uno de los principios del entendimiento puro que Kant considera en la Crítica de la razón pura, este es: el principio de las anticipaciones de la percepción. A saber, el principio que explica la condición de toda sensación. Para preguntar por una historia in-finita de la naturaleza es fundamental atender a la diferencia implicada en la relación entre naturaleza y arte que advierte Klee. Dicha diferencia conlleva considerar el origen de esta historia como fractura por la atención puesta hacia lo que la diferencia, lo cual exige pensar en lo que denomino un cambio de percepción.

ABSTRACT To approach an un-ending history of nature in Paul Klee's thought-in-images , I focus this work on an interpretation of paragraphs 76 and 77 of Kant's Critique of the faculty of Judgment. For its reading, I think that is necessary a counterpoint. This is, the principle of the anticipation of perception, one of the principles of pure understanding that Kant considers in the Critique of Pure Reason. Furthermore, in the in-between of that interpretation of paragraphs 76 and 77 of the Critique of the faculty of Judgment, in a genetical and genealogical manner, it seems fundamental to attend to the difference implied in the relationship between nature and art, which will entail to consider a break in the origin of an un-ending history of nature. This break requires to think what I name as a change of perception.

RESUMEN La modificación de la dialéctica que propone el planteamiento de Adorno despliega una crítica inmanente del principio identificatorio que emerge del conflicto entre componente somático y concepto, entre lo idéntico y lo no idéntico. Ello resulta fundamental para comprender la dominación como segunda naturaleza en las formaciones económico-sociales modernas/coloniales. En este trabajo proponemos, en primer lugar, examinar críticamente las relaciones de alteridad que estructuran la experiencia de lo político al interior de la modernidad/colonialidad, y la configuración de la subjetividad en términos sociohistóricos. En segundo lugar, se explora, desde un abordaje decolonial del horizonte analítico de Adorno, la constelación de mecanismos ideológicos vinculados al principio identitario que se condensa en la alteridad colonial, y que, como exponemos en este análisis, convergen finalmente en una metafísica del exterminio, en donde lo particular resulta subsumido por lo universal, y, que se efectualiza como una matriz de dominación en la que se articulan la experiencia de lo abyecto y los procesos de estereotipia que vertebran la construcción simbólica y racial de América.

ABSTRACT The modification of dialectics proposed by Adorno's approach displays an immanent critique of the identifying principle that emerges from the conflict between the somatic component and the concept, between identity and non-identity. This is essential to understand domination as second nature in modern/colonial social economic formations. In this paper, we propose, first of all, to critically examine the relationships of alterity that structure the experience of the political within modernity/ coloniality, and the sociohistorical configuration of subjectivity. Secondly, from a decolonial approach to Adorno's analytical horizon, we explore the constellation of ideological mechanisms linked to the identity principle that are condensed in colonial alterity, and, that, as we expose in this analysis, finally converge in a metaphysics of extermination, where the particular is subsumed by the universal, which is carried out as a matrix of domination in which the experience of the abject and the stereotyping processes that structure the symbolic and racial construction of America are articulated.

Abstract: The municipality of Cuautlancingo used to agricultural production was interfered by the insertion of new urban areas causing land use speculation resulting in the reconfiguration of public spaces such as streets and avenues. The objective is to illustrate how urban expansion, through changes in land use, has interfered with the socio-spatial valuation among the inhabitants of the neighborhood of San Juan and the new housing areas, leading to conflicts in the use, access, and appropriation of public space, exemplified by Morelos Avenue. The methodology used is of a mixed nature, using GIS for the spatial analysis of urban growth. Among the main findings, it is presented how the changes in land use in the last three decades and the appearance of new housing complexes affected the sociocultural valuation of the neighborhood of San Juan Cuautlancingo.

Resumen: El municipio de Cuautlancingo habituado a la producción agrícola fue interferido por la inserción de nuevas zonas urbanas provocando la especulación del uso de suelo, de modo que los espacios públicos como las calles y avenidas se han ido reconfigurando. El objetivo es mostrar cómo la expansión urbana por el cambio de uso de suelo ha ido interfiriendo en la valoración socioespacial entre los habitantes del barrio de San Juan y de las nuevas zonas habitacionales que chocan con el uso, acceso y apropiación del espacio público por sus diversas expresiones socioculturales y religiosas como es el caso de la Avenida Morelos. La metodología utilizada es de carácter mixto, utilizando los SIG para el análisis espacial del crecimiento urbano. Entre los principales hallazgos se presenta cómo los cambios de uso de suelo de las tres últimas décadas y la aparición de nuevos complejos habitacionales fueron afectando la valoración sociocultural del barrio de San Juan Cuautlancingo.

ABSTRACT The use of bioactive compounds from macroalgae in agricultural formulations is an emerging technology with great potential to reduce dependence on synthetic agrochemicals. Currently, seaweed extracts are considered a sustainable resource due to their biodegradable nature. This review discusses their potential to replace or reduce a variety of synthetic molecules in economically important crops, such as synthetic nitrogen and phosphate fertilisers, synthetic hormone growth regulators, and organochlorine and organophosphate pesticides. Due to the presence of a wide range of bioactive substances already reported in certain algae, they are foreseen as good candidates for the production of plant bioformulations. In this sense, the commercial and biotechnological exploitation of macroalgae could benefit the local economy. However, despite the potential of algae, there is very little information on their total metabolomic or chemical content. This literature review summarises information proposing the use of the macroalgae Kappaphycus alvarezii, Acanthophora spicifera and Hypnea spinella in the Ecuadorian agricultural sector as an alternative for pesticide reduction.

RESUMEN El empleo de compuestos bioactivos extraídos de macroalgas en forma de formulaciones agrícolas representa una tecnología emergente con gran potencial para reducir la dependencia de agroquímicos sintéticos. Al presente, los extractos de algas marinas se consideran un recurso sostenible debido a su carácter biodegradable. En esta revisión se discute su potencial para reemplazar o reducir a una variedad de moléculas sintéticas en cultivos económicamente importantes, tales como fertilizantes sintéticos nitrogenados y fosfatados, reguladores del crecimiento hormonales sintéticos y plaguicidas organoclorados y organofosforados. Por la presencia de una extensa gama de sustancias bioactivas ya registradas en ciertas algas se prevén como buenos candidatos para la producción de bioformulaciones vegetales. En este sentido, el aprovechamiento comercial y biotecnológico de las macroalgas podría beneficiar la economía local. Sin embargo, pese a todo el potencial de las algas existe muy poca información de su contenido metabolómico o químico total. Esta revisión bibliográfica resume información que propone el uso de las macroalgas Kappaphycus. alvarezii, Acanthophora spicifera e Hypnea spinella dentro del sector agrícola ecuatoriano como alternativa para la reducción de pesticidas.

RESUMEN El objetivo general fue analizar el mecanismo a través del cual la academia puede contribuir al logro de los Objetivos de Desarrollo Sostenible (ODS) en Paraguay. Ante la necesidad de visibilizar esta contribución por parte de la academia, se remarca el propósito del estudio, intercambiar experiencias de cómo puede la academia colaborar al logro de los ODS, la importancia de difundir informaciones relacionadas a los ODS y, sobre todo, indagar el grado de conocimiento de los ODS de personas clave de organizaciones o instituciones de las distintas comunidades de la zona de influencia de la sede Central y las Filiales de la FCE-UNA. El estudio analítico-descriptivo, está basado esencialmente en un trabajo de campo, con relevamiento de datos definida como población objetivo a líderes comunitarios. Los resultados obtenidos permiten afirmar que la visión de los líderes sobre el rol de las universidades para el logro de los ODS en Paraguay, refieren a que su rol es fundamental para el logro de los ODS y también mencionan que su rol es ser nexo con la sociedad para el logro de los ODS. Se concluye que el mecanismo óptimo a través del cual la academia/universidad puede contribuir al logro de los ODS en Paraguay, seria preferentemente incluir el tema de los ODS en el currículo de las facultades y brindar cursos sobre los ODS; otro, además sería elaborar e implementar proyectos en línea de los ODS, al que se agregan, el asesorar a las instituciones responsables del cumplimiento de los ODS.

ABSTRACT The overarching objective was to examine the manner in which academic institutions can contribute to the attainment of the Sustainable Development Goals (SDGs) in Paraguay. In light of the necessity to make this contribution by academia visible, the objective of the study is to facilitate an exchange of experiences on how academia can collaborate to achieve the Sustainable Development Goals (SDGs), the importance of disseminating information related to the SDGs, and, most importantly, to investigate the degree of knowledge of the SDGs among key individuals from organizations or institutions in various communities within the area of influence of the Central Headquarters and the Branches of FCE-UNA. The study is primarily analytical and descriptive in nature, with a particular focus on fieldwork and the collection of data from community leaders. The findings indicate that the leaders perceive the role of universities in achieving the SDGs in Paraguay to be of paramount importance. Furthermore, they assert that their role is to serve as a conduit between society and the achievement of the SDGs. It is thus concluded that the most effective mechanism through which academia/ universities can contribute to the achievement of the SDGs in Paraguay would be to integrate the topic of the SDGs into the curricula of the faculties and to offer courses on the SDGs. Additionally, another avenue for contribution would be the development and implementation of SDG-aligned projects, in collaboration with institutions responsible for achieving the SDGs

ABSTRACT "We are the trash, but the most important thing." The expression of a chambermaid sums up the fundamental tension of the so-called "care crisis", between the subordination of its protagonists due to the intersection of gender, class and foreign inequalities and the essential nature of this work for the sustain-ability of social life. This research adopts this perspective to offer proposals for improving the socio-legal methodology for analysing care-related rights. It does so based on the sector of chambermaids in tourist establishments in Spain and in particular through the experience of the Seville Union of Chambermaids (Kellys). Their experience allows us to reformulate the legal approach to their social rights. To this end, we present (1) the main violations of rights they identify; (2) the political-legal analysis these workers carry out on the inequalities that underlie these discriminations, as well as some reform proposals; and (3) the strategies for protection and self-protection of rights that they implement, both individually and collectively.

RESUMEN "Somos la basurilla, pero lo más importante." La expresión de una camarera de piso resume la tensión fundamental de la llamada "crisis de los cuidados", entre la subordinación de sus protagonistas por la intersección de las desigualdades de género, clase y extranjería y el carácter esencial de esa labor para la sostenibilidad de la vida social. Esta investigación adopta dicha perspectiva para ofrecer propuestas para mejorar la metodología socio-jurídica de análisis de los derechos relacionados con el cuidado. Lo hace a partir del sector de camareras de piso de establecimientos turísticos en España y en particular a través de la experiencia del Sindicato de Camareras de Piso (Kellys) de Sevilla. Su experiencia permite reformular el abordaje jurídico de sus derechos sociales. Para ello se exponen (1) las principales vulneraciones de derechos que identifican; (2) el análisis político-jurídico que las trabajadoras realizan sobre las desigualdades que subyacen a esas discriminaciones, así como algunas propuestas de reforma; y (3) las estrategias de tutela y autotutela de derechos que implementan, tanto individuales como colectivas.

Abstract: Coseriu’s three-dimensional conception of varieties does not take into account all the existing varieties: some do not fit into the established categories and the status of others is diffuse; given the multifactorial nature of the varieties, the diffusion can be attributed to several dimensions. His conception ignores the dynamic character of the social status ot the varieties in the course of evolution. This paper offers a deconstructivist analysis of essential points in Koch and Oesterreicher’s “variational chain”, a theory that postulates a fixed orientation between the varieties of the diasystem. Cristicism is levelled at the mechanical character of its conception and at the rigidity of its orientation. A different vision (inspired by the energeia of Humboldt, including the role of the speaker) is proposed that considers varieties as a device that must be analyzed as a contact between varieties.

Resumen: La concepción tridimensional de variedades de Coseriu no considera todas las variedades de lengua que existen; además, algunas no caben en las categorías establecidas y el estatus de otras es difuso, lo que -por su carácter multifactorial- puede atribuirse a varias dimensiones. Tal concepción ignora el carácter dinámico de su naturaleza social a lo largo de la evolución. Mediante un análisis deconstruccionista, en este trabajo se cuestionan puntos esenciales de la “cadena variacional” (Koch y Oesterreicher) que postula una orientación fija entre las variedades del diasistema; se critica el carácter mecánico de esta concepción y la rigidez de la orientación; por último, se propone otra visión (inspirada en la energeia de Humboldt, incluido el papel del hablante) que considera las variedades un dispositivo que debe analizarse como contacto entre variedades.
