The research analyzes the tax reforms implemented during this period and their impact on the national economy. These reforms included modifications in direct and indirect taxes, such as the Value Added Tax (VAT) and the Income Tax, aimed at increasing tax collection and stabilizing public finances after the economic crisis of the late 1990s. The study evaluates how these measures affected the productive and commercial sectors, highlighting both their benefits and limitations. On the one hand, greater tax revenues were achieved, but, on the other, significant challenges were identified for small and medium-sized businesses, such as the growing tax burden and economic informality. The analysis concludes that, while the reforms contributed to fiscal sustainability, a more balanced approach is necessary to promote economic growth and business competitiveness.

Introduction: Digital convergence has driven the immediate dissemination of information, but this affects and promotes challenges in conventional journalism such as the lack of verification and context. AI emerges as a key tool to improve the process of creating journalistic content in a precise and efficient way. Objectives: analysis of a case study, which exemplifies the implementation of AI in the journalistic field, allowing to evaluate its impact on quality, effectiveness, as well as the ethical aspect in the production of news content. Methodology: qualitative approach through the case analysis of the media outlet "Channel 1", founded in 2023. The use of artificial intelligence for the creation and dissemination of content on digital platforms was evaluated, considering consumption trends in social networks and the analysis of the algorithms used for the automatic generation of news and their impact on journalism. Results: the analysis conducted on "Channel 1", a media outlet founded in 2023 that uses AI to create content adapted for instant consumption on social networks. Its objective is to offer accurate information through algorithms that analyze trends. AI automates the writing of news stories, distributed across multiple platforms. Prioritize visual content and feedback with the audience for reliability and creativity. Conclusions: Traditional journalism prioritizes objectivity, the search for truth, but faces challenges in the digital environment. Digital journalism, on the other hand, is characterized by hyper textuality, multimodality, and interactivity, adapting to new forms of consumption. General area of study: communication. Specific area of study: journalism. Type of article: Bibliographic review-case study.

Introduction: The presumption of the time of conception established in article 62 of the Ecuadorian Civil Code expressly establishes that conception precedes birth in ranges of one hundred and eighty days to three hundred days, a notion that constitutes a presumption of law, that is, it does not admit contradictions, having the main objective to establish filiation, however, currently due to the multiple scientific and technological advances there are methods that allow determining filiation with greater precision, for which said presumption is obsolete not only because of its rigidity in the range it establishes to determine conception but also because of the fact that it does not admit evidence against it even when thanks to technology it has been possible to evidence the deficiencies of this, to the point of even violating fundamental rights. Objective: To analyze the presumption of the time of conception, its legal implications, and challenges in determining filiation in the Ecuadorian Civil Code, to protect the rights derived from it. Methodology: The research will use analytical and analogical methods to address the shortcomings of the presumption of the time of conception in parental filiation and argue the need to adopt modern technologies based on the analysis of foreign legislation. Conclusions: Given this problem, the need to modify article 62 is highlighted, so that the presumption "of law" becomes simply legal, which would allow the admission of contrary evidence, and would better adjust to the current state and scientific reality. It is worth mentioning that Ecuadorian law, being of a progressive nature, must adapt the laws and prevent violations from occurring. General study area: Law and administration of justice. Specific study area: Family civil law. Type of study: Systematic bibliographic review.

Introduction: The main purpose of the research article entitled "Evaluation of the effectiveness of anti-doping legislation in Ecuador: Analysis of legal gaps, implementation challenges and international comparison" is to analyze the legal regulation of Sports Law in Ecuador with respect to doping. To this end, the effectiveness of the current regulations, compliance with international standards and the criteria applied to determine the corresponding sanctions are examined. Objectives:  the general objective encompasses the evaluation of the effectiveness of anti-doping legislation in Ecuador to identify legal gaps and challenges in its implementation, in terms of the specific ones that are three, analyze the current regulatory provisions and alignment with international standards, analyze the performance of sports authorities, anti-doping controls and sanctions,  Finally, to analyze the anti-doping legislation in Ecuador and other countries   Methodology: it was carried out taking into consideration the exploratory and explanatory methodology, covering the analytical level. For the collection of information, the bibliographic review technique was applied, and an analysis was conducted in the related national and international legislation, as well as the possible existing legal gaps. Results: The analysis has determined that although Ecuadorian regulations are linked to both national and international steps and procedures designed to combat doping in sport, they present certain legal gaps, highlighting aspects such as the definition of doping, its characteristics, control methods and mechanisms, the dissemination of its consequences through information campaigns,  the applicable sanctions and the delimitation of the competences of the administrative and judicial bodies responsible for judging these cases. These gaps could be filled through a reform of Title XII "Anti-Doping Control" of the Law on Sports, Physical Education and Recreation, which would strengthen the processes of prevention, control, and sanction of sports doping. Conclusions: The research identifies regulatory gaps and challenges in the implementation of anti-doping legislation such as lack of control, sanction, and education. Recommending reform of regulations, allocating resources, and promoting education and awareness. General area of study: Law. Specific area of study: sports law, anti-doping legislation.
