This study explores the effectiveness of social media among adults aged eight-een and above, focusing on its impact across four domains: communication and well-being, information sharing and dissemination, professional development and networking, and activism and civic engagement. This research uses a mixed-methods approach, integrating both quantitative surveys and qualitative interviews to explore social media usage patterns, benefits, and challenges. Findings indicate that social media increases communication through connection making and emotional support, despite the fact that some users suffer from negative effects such as anxiety and dependency. Social media are essential for information sharing, disseminating information fast and acquiring diverse per-spectives; however, miscommunication is a significant issue. Platforms like LinkedIn are important tools for professional networking and advancement in career; however, privacy issues limit participation. Social media also enables civic engagement and activism, giving users a voice to mobilize for social causes, though algorithmic biases and echo chambers constrain diverse participation. Social media offers both opportunities and challenges for personal and societal growth. Risks, of course, must be mitigated, but the recommendations do include fostering digital literacy, algorithmic transparency, better privacy protections, and responsible platform use. These insights are foundational in understanding social media's place in the modern adult's life and will form the basis of future research and policymaking.

Introduces and developed a novel computational approach for efficiently calculating the navigation of infinite multi-dimensional spaces using a improved algorithm named Bellande Step function within a infinite multi-dimensional model-integrated framework. By optimizing and advancing the step function, the method addresses challenges in infinite-dimensional random point generation and nearest node calculation in in an existing tree while moving from the nearest node towards a random point by a step size collision free, allowing movement towards target nodes within defined distance constraints to be added as node to the tree. Leveraging this type of approach, efficiently compute the next step towards a target node for infinite-dimensions, ensuring accurate movement while reducing collisions with adhering to specified distance limits set by the user. The integration of infinite dimensional space modeling enhances the process of the step function while increasing the capabilities, accuracy, adaptability, effectiveness and computational efficiency. The results underscore the robustness and scalability of this approach, showcasing its potential applications in robotics and other fields related to robotics, and complex systems modeling. This integration of the Bellande Step function with model-integrated infinite dimensional space represents a significant advancement in the computational efficiency, precision, accuracy of Infinite multi-dimensional node calculations.

In this article, fundamental aspects of geology and soil science will be studied through the development of a practical workshop aimed at applying the knowledge acquired in the course. This exercise seeks to have students consult, analyze, and integrate information from various reliable sources, thereby strengthening their research skills and understanding of the geological and edaphological environment of the Colombian territory. The content of the work is structured into five sections. First, the main rock dating methods will be addressed, which are essential for establishing the relative and absolute age of geological formations. Second, a mind map of the Geoportal of the Colombian Geological Service (SGC) will be presented, summarizing the key information offered by this institutional platform. Subsequently, the characteristics and distribution of two important soil types in Colombia—Andisols and Inceptisols—will be described, detailing their physical and chemical properties, as well as the regions of the country where they are predominantly found. Finally, a conceptual scheme based on the CORINE Land Cover methodology adapted for Colombia will be developed, showing the relationships among different land cover types present in the national territory. This academic exercise aims to reinforce critical analysis, the use of cartographic tools, and an integral understanding of the physical environment, which is essential for training in disciplines such as geology, civil engineering, and territorial planning.

Hemos desarrollado un enfoque combinatorio fundamentado en el Triángulo de Pascal para abordar el problema clásico de las sumas de potencias de números naturales. Este método se basa en tres secuencias clave derivadas del triángulo: los coeficientes binomiales, los números de Narayana y una variante de los coeficientes binomiales. A través de estas secuencias, hemos formulado tres estrategias sistemáticas: el Método Directo (M.D), el Método de Coeficientes (M.C) y el Análisis de Coeficientes (A.C), las cuales potencian tanto la aritmética como el reconocimiento de patrones numéricos, alcanzando resultados equivalentes a los obtenidos mediante enfoques puramente algebraicos, como las sumas telescópicas.

The rapid shift to hybrid work accelerated by the COVID-19 pandemic has fundamentally transformed organizational dynamics highlighting the need for innovation leadership in distributed environments. This paper addresses the evolving challenges of managing innovation in hybrid settings where traditional frameworks often fall short due to their reliance on co-located teams. The objective is to critically evaluate existing innovation frameworks and leadership models, identifying their limitations in hybrid contexts and propose a new hybrid-optimized innovation leadership framework. Through secondary research and a comprehensive literature review, this study synthesizes relevant academic and industry insights including perspectives on transformational, servant and digital leadership as well as innovation models such as Doblin’s Ten Types of Innovation and Open Innovation. The Hybrid Innovation Alignment Model (HIAM) is introduced, focusing on six guiding principles trust-based autonomy, digital inclusion, asynchronous collaboration, psychological safety, purpose-driven connectivity, and adaptive leadership. Key findings indicate that a hybrid-specific framework can foster innovation by integrating digital tools and adaptive leadership styles, while supporting asynchronous workflows and remote collaboration. This paper contributes both theoretically and practically by offering a flexible framework for hybrid teams, enhancing innovation processes and leadership effectiveness in increasingly distributed work environments.

ABSTRACT: INTRODUCTION: Communicating bad news is challenging in everyday clinical practice; the incorporation of artificial intelligence (AI) offers opportunities for ethical and effective optimization but raises ethical concerns about preserving empathy and humanization in the physician–patient relationship.METHODS: A scoping review was conducted according to PRISMA-ScR (2018–2024) in the PubMed/MEDLINE, SciELO, and BVS databases, with no language restrictions. Four search strategies retrieved fifteen unique records; eleven studies were selected after dual independent screening of titles, abstracts, and full texts. RESULTS: The narrative analysis identified five main strands: Symptom checkers that enhance autonomy in initial triage but lead to unnecessary referrals. Large language models used in radiology reporting and patient messaging, which speed up report drafting but function as “black boxes,” requiring human review to maintain an empathetic tone. Scientific writing tools that improve manuscript fluency without replacing subject-matter experts. Hybrid protocols (SPIKES AI) that show promise but have been little tested in real-world settings. Ethical challenges such as embedded biases, model “hallucinations,” and lack of transparency. CONCLUSION: AI can alleviate the technical workload of delivering bad news but cannot replace empathetic human interaction. We recommend developing conducting randomized trials to assess impacts on empathy, satisfaction, and patient outcomes in both the short and long term.
