ABSTRACT Objective: To recognize and address Patau’s syndrome, despite its rarity and associated low life expectancy, through the presentation of a case study of a 2-year-old patient receiving Home Care services. Case description: We present a female patient who defied the odds with a prolonged survival, possible due to Home Care. She was delivered via cesarean section at 31 weeks + 4 days due to restricted uterine growth. The mother, aged 36, had received proper prenatal care and was in good health. The diagnosis of Patau’s syndrome was confirmed through karyotyping after birth. Despite the severe clinical nature of the case, the patient, now with two years old, receives specialized home-based care, supported by a tracheostomy and gastrostomy. A dedicated 24-hour nursing technician ensures continuous monitoring, and the patient benefits from regular medical check-ups, physiotherapy five times a week, weekly speech therapy sessions, monthly consultations with a nutritionist, and ongoing psychological support for her family members. Comments: This multidisciplinary approach has resulted in a slight motor response, highlighting the positive impact of comprehensive care on her overall well-being. The existence of a robust support network for families facing similar challenges is crucial, and a multidisciplinary care can effectively prevent complications associated with this impactful syndrome.

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

Abstract The methodological progress of Political Science in the last three decades has generated important epistemological changes, the effects of which affect the scope of consolidated theories. Among these changes, I argue that the causal assessment of the impact of institutions on political behavior faces challenges that have been disregarded when focusing on singular cases. This arises from the incompatibility of the causal structures underlying the theoretical formulation used and the case study. To highlight this situation, I consider the methodological dimension present in the emergence of the concept of coalition presidentialism. The present debate still carries an imprecise epistemological conception concerning the theoretical use that predicted the institutional impasse caused by the 1988 Constitution. This analysis proves to be relevant both because this finding is absent in part of current research, as well as for highlighting the affinity between methodological production and theoretical formulation in Political Science, and also for its effects on research designs. changes theories cases study situation presidentialism 198 Constitution designs 19 1

Résumé Les progrès méthodologiques de la science politique au cours des trois dernières décennies ont généré d’importants changements épistémologiques, dont les effets affectent la portée des théories consolidées. Parmi ces changements, je soutiens que l’évaluation causale de l’impact des institutions sur le comportement politique se heurte à des défis qui ont été négligés lorsqu’on s’est concentré sur des cas singuliers. Cela résulte de l’incompatibilité des structures causales qui sous-tendent la formulation théorique utilisée et l’étude de cas. Pour mettre en évidence cette situation, je considère la dimension méthodologique présente dans l’émergence du concept de présidentialisme de coalition. Le débat actuel porte encore une conception épistémologique imprécise quant à l’usage théorique qui prédisait l’impasse institutionnelle provoquée par la Constitution de 1988. Cette analyse s’avère pertinente à la fois parce que ce constat est absent d’une partie des recherches actuelles, mais aussi pour mettre en évidence l’affinité entre production méthodologique et formulation théorique en Science Politique, mais aussi pour ses effets sur la conception des recherches. dimportants d importants épistémologiques consolidées lévaluation l évaluation limpact impact lorsquon lorsqu on sest s singuliers lincompatibilité incompatibilité soustendent sous tendent létude étude situation lémergence émergence coalition lusage usage limpasse impasse 1988 savère avère dune actuelles laffinité affinité Politique 198 19 1

This article discusses guidance published on official websites regarding the response of the Brazilian National Health System (SUS) psychosocial care networks (RAPS) to the public health emergency caused by Covid-19. The discussion draws on the analysis of online materials published between 06/02/20 and 31/08/21 at state and federal level across all the country’s state capitals. We compare the results of the document analysis with guidance published by international organizations to reflect on the challenges, successes, mistakes and omissions in the guidance given to the RAPS at the beginning of the pandemic. It is concluded that, despite being formal, the guidance was poorly coordinated and integrated into the networks and with other sectors and pre-existing challenges, as recommended by the international community.

ABSTRACT The ‘RD6’ glutinous rice (Oryza sativa L.), developed from the popular aromatic rice ‘KDML105’ through gamma irradiation, is a key economic cultivar widely consumed in Thailand and exported throughout Asia. However, cultivation of the ‘RD6’ faces challenges due to its low grain yield and growth performance. The objective of this study was to use biostimulant chitosan and brassinosteroids to promote growth performance, nutrition, and yield of the ‘RD6’ rice. Chitosan (2.5, 5.0, 7.5, and 10.0 mg L-1) and brassinosteroids (0.00005, 0.0005, 0.001, and 0.002 mg L-1) were sprayed twice at 40- and 75-d-old rice plants in paddy fields. The results demonstrated that foliar spraying with 7.5 mg L-1 chitosan can promote leaf growth of ‘RD6’ and improve grain yield by 24% as compared with the control. More pronounced effects were observed with 0.002 mg L-1 brassinosteroid, improving not only growth but also ‘RD6’ yield by 41.8% compared to the control. Moreover, 0.002 mg L-1 brassinosteroids can enhance antioxidant capacities (total phenolic contents), elemental K and Ca contents, and the aroma compound 2-acetyl-1-pyrroline (2AP) contents in the rice grains. Furthermore, the use of 0.002 mg L-1 brassinosteroids proved to be a financially sound investment, yielding superior net returns and an advantageous benefit-cost ratio compared with 7.5 mg L-1 chitosan. Therefore, the use of exogenous brassinosteroids on glutinous rice in this study offers promising advantages for promoting the growth and physiological performance of rice plants.

Abstract The improper disposal of this waste poses environmental challenges, which can be addressed through effective reuse strategies. This study aims to explore the potential of utilizing marine shell waste as partial substitutes for aggregates in concrete. The research involves investigating the physical characteristics of the recycled aggregate using Atomic Force Microscopy (AFM) and Scanning Electron Microscopy (SEM) techniques to elucidate the contact surface with the paste. Additionally, chemical and mineralogical characteristics are analyzed through X-ray fluorescence and X-ray diffraction tests. The compressive strength test is conducted on concrete samples to assess the performance of these materials as both aggregate (shell type A) and filler (shell type B). The findings indicate that replacing up to 20% of marine shells as coarse aggregate and 10% as filler demonstrates feasibility for applications in structural concrete. Furthermore, up to 30% replacement can be directed towards non-structural concrete, providing a comprehensive understanding of the potential applications of marine shell residues in concrete production. challenges strategies AFM (AFM SEM (SEM paste Additionally Xray X ray tests A B.

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.
