The Cuban cooperative movement and its foundation in the ideological legacy of Fidel Castro Ruz
type: item
description: To carry out the socialist transformation of Cuban agriculture and to fulfill one of the issues raised in the Moncada Program, Commander in Chief Fidel Castro granted peasants a portion of the lands confiscated from large landowners and, years later, invited them to join the agricultural cooperatives that were established to further integrate them into the process of building socialism and strengthening the worker-peasant alliance. This article aims to reflect on the development of the Cuban cooperative movement across its different stages, using Fidelist thought as the guiding thread. For this purpose, the universal dialectical materialist theoretical method and its specific methods were used: the unity of the logical and the historical, analysis and synthesis, as well as scientific abstractions. These methods were employed to analyze, in a periodized manner, the development of the cooperative process in Cuba and to understand that, under the leadership of Fidel Castro, the Cuban Revolution found in agricultural cooperativism a key model of cooperation, effective for modernizing crop production and for the collective use of land.

The use of financial software in economic analysis and business decision-making
type: item
description: The use of technological tools in financial management has become a determining factor in improving the efficiency of economic analysis and the quality of business decisions in competitive environments. The objective of this article is to analyze the influence of financial software on economic analysis and business decision-making, considering its impact on the objectivity, precision, and sustainability of organizational management. The research was conducted using a mixed-methods approach, and the data were processed using descriptive statistics and correlation analysis techniques, which allowed for the identification of a significant relationship between the level of financial software use and the quality of business decisions. The results showed that organizations that systematically use these tools exhibit a higher level of efficiency in economic evaluation, a reduction in financial risk, and more well-founded decision-making compared to those that rely on traditional methods. Additionally, limitations associated with staff training and resistance to organizational change were identified, which affect the full utilization of these technologies. It is concluded that financial software constitutes an indispensable strategic support for economic analysis and business decision-making, provided it is integrated with sound managerial judgment and appropriate organizational processes.

The convergence of economic cycles in Latin America: a critical review of the scientific literature
type: item
description: The article analyzed the current state of research on the convergence of economic cycles in Latin America through a critical review of the relevant literature. The objective was to determine whether economic cycles in the region have tended to synchronize over time and what factors drive such synchronization. To this end, a systematic review methodology was applied, using academic search platforms, databases, and directories. Inclusion criteria were established: publication from 2020 onward, availability in Spanish or English, scientific article format, empirical focus, and thematic relevance; and exclusion criteria: length under four pages, thesis or book format, and duplicates. The analysis shows that evidence of a common economic cycle in Latin America is scarce. Although episodes of subregional convergence are observed, synchronization varies between countries and depends heavily on international trade. Trade flows carry more weight than financial ones in short-term cyclical comovements, and the region maintains a strong dependence on external shocks, especially since the 2008 crisis. In conclusion, there is no clear or consistent trend towards cyclical convergence across the entire region.

Pedagogical communication as a tool for the teacher
type: item
description: The study of communication is extremely important for all those who are going to develop an educational task. This is so because, throughout their pedagogical activity, teachers establish constant communication with students. The purpose of this article is to reflect on communication as a tool that teachers can use successfully in their professional performance. To this end, philosophical, sociological, psychological and pedagogical foundations were taken into consideration, as well as theoretical (analysis-synthesis, induction-deduction and historical-logical) and empirical methods, such as the critical analysis of documents. The research was important because it made possible the analysis of communication through its functions, styles, mechanisms and skills, considering it as an essential element to exert a positive influence between teachers and students, which resulted in the successful management of the teaching-educational process.

Anxiety and temporomandibular disorders: a brief approach to their study for a better quality of life
type: item
description: Anxiety and depression are closely related to the appearance and evolution of temporomandibular disorders. In particular, dental anxiety nowadays constitutes a psychopathological problem of high prevalence in Latin American and Caribbean countries, with importance in the dental area, particularly with temporomandibular disorders. The article analyzed the relationship between anxiety and temporomandibular disorders in order to promote strategies that contribute to achieve a better quality of life in people. Theoretical methods (analysis-synthesis and induction-deduction) and empirical methods (analysis and critique of sources as well as scientific observation) were used. Emphasis was placed on a group of psychological references for the diagnosis and treatment of temporomandibular disorders, as well as on the need to promote strategies for the prevention and management of anxiety. As a result, it was obtained that the bidirectional interaction anxiety-temporomandibular treatment generates a negative cycle if the treatment is not systematic; that the early identification of anxiety symptoms and their preventive treatment reduce the risk of developing temporomandibular disorders in predisposed individuals, which improves the quality of life and reduces the burden of oral and psychological disorders; the implementation of strategies for the treatment of anxiety associated with temporomandibular disorders requires the systemic integration of the multidisciplinary team for the diagnosis, orientation, treatment and evolution of patients.

Strategy for the socio-humanistic training of medical students at the Military Hospital of Holguín
type: item
description: Education in the socio-humanistic field for medical students is considered an urgent need in view of the current challenges of building a more equitable and inclusive society. The objective of this article is to propose a strategy that contributes to the socio-humanist education of medical students of the Military Hospital of the Army Dr. Fermín Valdés Domínguez, Cuba. A qualitative research was carried out, based on theoretical (historical-logical, analysis-synthesis and induction-deduction) and empirical (documentary analysis) methods. The choice of these methods allowed for a qualitative analysis and interpretation of the content presented, in addition to facilitating the application of the laws and principles of dialectical materialism, including the systemic structural-functional approach. In spite of the fact that the curricula of the medical career in Cuba have integrated in a transversal way socio-humanistic elements, the research shows that there are still deficiencies in their effective implementation. As a proposal to address this situation, a strategy was designed to strengthen socio-humanistic training in medical students, not only as a curricular requirement, but as an integral and formative process that influences all aspects of their professional and personal development

Workplace well-being in human talent productivity from the perspective of organizational psychology
type: item
description: Workplace well-being has gained increasing relevance as a determining factor in employee performance, especially from the perspective of organizational psychology. This study analyzed how the psychosocial conditions of the work environment directly influenced the productivity of human talent within private companies. The main objective was to analyze the impact of well-being at work on the productivity of human talent from the perspective of organizational psychology. A quantitative approach with a non-experimental, correlational design was applied through surveys based on the Likert scale to a representative sample of employees in companies in Quevedo, Ecuador. The results showed that high levels of well-being at work are positively associated with greater efficiency, commitment and individual performance. In addition, the influence of organizational practices oriented to the emotional care of personnel in strengthening productivity was highlighted. It was concluded that an adequate management of labor welfare contributes significantly to the development of human talent, and it was therefore suggested that sustainable welfare strategies be integrated into corporate policies.

Training of professional interests in the students of annex 1 of Technical Vocational Education
type: item
description: Professional orientation is a process that needs to be strengthened in vocational students of Technical and Professional Education, with special interest in those trades that society demands with greater emphasis. In view of this imperative, the article presents a proposal of orientation workshops for the development of professional interests in trade students of Annex 1, belonging to the educational institution Enrique Rosa Pérez Polytechnic Center. Theoretical (analytical-synthetic, modeling), empirical (observation, interview, documentary analysis) and statistical (descriptive and inferential statistics) methods were used. The proposal was a concrete response to the contradiction between the direction of the professional orientation process and the demands of the students' work performance. Likewise, it contributed to the psycho-pedagogical preparation of the educators to positively influence the development of the professional interests of the students, in order to guarantee the obtaining of the necessary information about the different trades to carry out a successful work activity. The use of field experimentation made it possible to demonstrate the feasibility and effectiveness of the proposed workshops and made their application advisable.

Case report of critical aortic coarctation
type: item
description: Aortic coarctation is a potentially critical congenital heart disease, in which there is a narrowing of the lumen of the descending aorta. This condition causes, depending on its severity, inadequate blood flow to the systemic circulation so that, on certain occasions, the flow to the portions irrigated by the descending aorta is determined by the presence of the ductus arteriosus. The aim of this article is to describe the clinical presentation of a newborn with a diagnosis of critical aortic coarctation from the current medical position. For this purpose, the clinical case of a patient treated in the perinatal intensive care unit of the Fe del Valle Ramos Hospital in Manzanillo, Granma, was presented. The clinical, echographic and electrical diagnosis of a critical heart disease was made in secondary health care and his subsequent optimal referral to the William Soler Pediatric Cardiocenter in Havana, where corrective surgery was performed to restore cardiovascular functionality. For discussion, a review of the literature was carried out using search engines, meta-search engines and databases (Google Scholar, PubMed, Science Direct and Scopus). The relevance and novelty of approaches in the diagnostic and therapeutic approach to aortic coarctation as a sufficiently developed area in the knowledge of medical sciences is confirmed from a literature review based on an information search strategy.

Financial control tools in Quevedo's commercial sector: level of application and challenges
type: item
description: Financial control is essential for business sustainability, especially in highly competitive environments. The article analyzes the level of application of financial control tools in the commercial sector of Quevedo and the challenges faced by companies in their implementation. The research was conducted using a mixed-method approach, applying surveys to 300 commercial enterprises of various sizes and interviews with managers and accountants. Data were processed using statistical techniques and qualitative analysis. The results show that the application of tools such as budgets, cash flow statements, and internal audits is high in medium-sized enterprises but limited in micro-enterprises. Digitalization shows progress, with a predominant use of spreadsheets in small businesses and ERP systems in medium-sized ones. Among the main challenges identified were a lack of training, high implementation costs, and limited financial literacy. It is concluded that company size is a determining factor in the adoption of control mechanisms, and that it is necessary to strengthen training programs and incentives to promote financial modernization in Quevedo's commercial sector.

Didactic strategy for the teaching and learning of chemical reactions: experiential research
type: item
description: The article addresses the issue of deficiencies in the teaching-learning process of the Chemistry subject at the pre-university level. The study was conducted through experimentation-reflection with 30 10th-grade students from the Roberto Ramírez Delgado Pre-University Institute in the municipality of Niquero, during the 2024-2025 academic year. The objective was to propose a didactic strategy to enhance the learning of exothermic and endothermic chemical reactions among the 10th-grade students at the studied pre-university institute. Research methods from the following levels were employed: theoretical (analytic-synthetic, inductive-deductive, and the systemic-structural-functional approach); empirical (observation, survey, interview, and pedagogical test); and mathematical-statistical (descriptive statistics and percentage calculation). The implementation of the strategy contributed to enabling students to visualize abstract concepts through experimental practice and, in turn, develop aptitudes and skills in the laboratory. Furthermore, it helped develop critical thinking, consideration of different viewpoints, as well as promote self-assessment; all of this fostered students' motivation in studying chemistry and the content of chemical reactions. The main results obtained showed that, once the didactic strategy was applied, the students successfully solved problems, and at the cognitive level, results were higher than those initially presented.

The technological convergence in the organizational communication management of the Majibacoa Municipal University Center
type: item
description: Technological convergence in the organizational communication management of the Majibacoa Municipal University Center is presented as a key strategy for modernizing internal and external communication processes, through optimal interaction among teachers, students, administrative staff, and the community. This approach integrates digital tools such as collaborative platforms, websites, social media, and content management systems, enabling greater efficiency in the dissemination of information and in decision-making. Furthermore, it strengthens institutional positioning and engagement with the local environment. However, its implementation faces challenges such as the digital divide, the need for training, and secure data management. The article analyzes how technological convergence can transform organizational communication in the university context by implementing actions to overcome its challenges and maximize impact. For this, the research process utilizes theoretical-level methods such as analytical-synthetic and inductive-deductive, as well as empirical-level methods, such as the analysis and critique of sources and observation. It is confirmed that the adoption of these technologies not only improves institutional management but also contributes to local development by promoting a more connected, innovative higher education aligned with the demands of today's digital society. The study offers a reference framework for similar institutions seeking to integrate technology into their communication processes.

type: item
description: To evaluate the response of the cowpea variety Vigna Yarey from the Tropics to the compounds Fitomás E, mycorrhizae, and Codafol, the research was conducted in the self-provisioning area of Cerca Blanca, Bayamo municipality, Granma province. Four treatments were established, each with an area of 28,8 m²: T1 (NPK: 7,5-7-12 at 1 t/ha⁻¹), representing the control treatment; T2 (Codafol: 1,5 l/ha⁻¹); T3 (Fitomás E: 2,0 l/ha⁻¹) and T4 (mycorrhizae: 1 kg/46 kg of seeds). The planting distance used was 0,80 m x 0,10 m, and a completely randomized experimental design was implemented. Plant height, number of pods and grains per plant, 100-seed mass (g), and yield (t/ha⁻¹) were evaluated. The data were processed using the statistical package InfoStat 2017, and Tukey's test was performed for p≤ 0,05. The best results in productive and economic indicators were found with the use of treatment T4 (mycorrhizae: 1 kg/46 kg of seeds), which achieved a yield of 3,22 t ha⁻¹ and a profit that exceeded the control (NPK) by 39,49 %.

Use of Moringa oleifera flour for the development of herbivorous carp fingerlings
type: item
description: The study was conducted at the Base Business Unit Acuipaso, in the municipality of Bartolomé Masó, Granma, with the aim of evaluating the inclusion and productive impact of Moringa oleifera leaf meal on the bioproductive indicators of herbivorous carp (Ctenopharyngodon idella) fingerlings under the conditions of this province. A completely randomized design was used, consisting of 12 floating cages (0.15 m³ each), with 10 fish per cage, four treatments: 0 %, 4 %, 7 %, and 10 %, and three repetitions each. The ration was adjusted weekly based on 4 % of body weight per day, with a frequency of 3 times a day (at 8:00 a.m., 12:00 p.m., and 4:00 p.m.). Data were analyzed using one-way ANOVA and Tukey's test (p<0.05); data normality was checked using the Kolmogorov-Smirnov test, and homogeneity of variance between treatments was evaluated using Bartlett's test. It was concluded that Moringa oleifera leaf meal, due to its chemical composition and low content of secondary metabolites, represents a viable alternative feed for inclusion in fingerling diets. Optimal values were achieved up to 4% in the formulation, where it showed excellent results and demonstrated the best productive contributions. From an economic standpoint, it was also confirmed that its use up to 10 %, as an alternative feed, reduced production costs but resulted in low productive performance during this fingerling stage.

Fascioliasis in cattle of the Basic Cooperative Production Units in the Bayamo municipality (2021-2023)
type: item
description: Fascioliasis is a parasitic disease with significant economic and zoonotic impact. The objective of this article is to analyze its epizootiological situation and effects in the cattle Basic Cooperative Production Units of the Bayamo municipality during the years 2021, 2022, and January-August 2023. For this purpose, Benedek sedimentation coprology was performed from June to August 2023 on representative samples from the selected populations. Prevalence, focality, and lethality were analyzed among the cooperatives by comparing proportions. Losses were estimated at an 8 % reduction in weight for sick animals, 0.5 kg of milk daily per milking cow, and $82,14 pesos per kilogram of condemned livers, according to authoritative references. The prevalence was 24,46 %; focality 67,56 %; and lethality 8,71 %, respectively. In the Manuel Espinosa, Manuel Pedreira, Roberto Elías, and Camilo Cienfuegos Basic Cooperative Production Units, prevalences were significantly higher than in Francisco Suárez Soa and Batalla de Peralejo (P≤0.01). The differences between totally and partially condemned livers (37,61 % vs. 8,52 %) suggest a high infestation intensity. It was concluded that fasciolosis is a real problem that caused million-dollar losses in the studied livestock sector; this disease was conditioned by edaphoclimatic factors, as well as by deficiencies and violations in management, feeding, water supply, diagnostic management and level, veterinary assistance, and irregularities in the Fasciolosis Control Program. Its solution requires immediate, coordinated, and effective actions by the competent authorities.

Cost-benefit impact on investment decision-making in commercial companies in Quevedo
type: item
description: Investment decision-making is a crucial aspect of business management, as it determines the efficiency of resource allocation and the sustainability of organizations. This article aimed to analyze the impact of cost-benefit analysis on the investment decisions of commercial companies in Quevedo, by identifying its influence on profitability and business competitiveness. The research was conducted using a mixed-methods approach, with a descriptive and correlational design, utilizing structured surveys applied to a representative sample of 120 companies and interviews with managers to complement the interpretation of the data. Statistical analysis identified a significant relationship between the systematic application of cost-benefit analysis and financial results, showing that organizations that use profitability indicators such as the internal rate of return and net present value achieve higher levels of success compared to those that base their decisions on intuition. Likewise, it was evidenced that medium and large companies apply these tools more frequently compared to micro and small enterprises, where limitations related to financial training and the estimation of indirect costs persist. It is concluded that the use of cost-benefit analysis is a key factor for sustainability and business competitiveness in the local context, which is why it is recommended to strengthen technical training and the incorporation of new technologies that enhance the accuracy of evaluations.
